As shown in FIG. 1 to FIG. 42, one embodiment of the present application discloses water divider structure. The water divider structure includes a pressure source 1300, a water divider 1400, and a first unidirectional valve 1430. The pressure source 1300 is used to connect a water supply tank 1200, and the water divider 1400 includes a first distribution channel 1410 and a second distribution channel 1420, both of which are connected to the pressure source 1300. The first unidirectional valve 1430 is connected between the pressure source 1300 and the water divider 1400. The first unidirectional valve 1430 is able to connect the pressure source 1300 and the water divider 1400 under the pressure formed when the pressure source 1300 is activated.

The pressure source 1300 can be applied by a water pump. When the pressure source 1300 is turned on, the water of the water supply tank 1200 can be supplied to the water divider 1400, thereby generating a larger water pressure. Only then can a sufficient water pressure value be generated to open (turn on) the first unidirectional valve 1430. When the pressure source 1300 is turned off, the water in the water supply tank 1200 cannot generate enough water pressure, and then the first unidirectional valve 1430 cannot be flushed, so that when a main body is shut down or stops working, the water in the water supply tank 1200 cannot pass through the first unidirectional valve 1430.

When there is residual water in the channel between the first unidirectional valve 1430 and the water divider 1400, the first unidirectional valve 1430 prevents the water in the water supply tank 1200 from being transported downstream. At this time, one end of the water channel downstream of the first unidirectional valve 1430 is closed, and one end of the water divider 1400 is connected to the air. Under the action of atmospheric pressure, the sealing effect of the first unidirectional valve 1430 prevents the water in the channel between the first unidirectional valve 1430 and the water divider 1400 from flowing out of the main body, solving the problem of water leakage and ensuring the cleanliness of the ground.

In one embodiment, the first distribution channel 1410 and/or the second distribution channel 1420 is provided with a second unidirectional valve 1440. The second unidirectional valve 1440 can open (turn on) the first distribution channel 1410 and/or the second distribution channel 1420 at a pressure formed when the pressure source 1300 is activated. The second unidirectional valve 1440 can close one end of the first distribution channel 1410 or the second distribution channel 1420 and open the other end of the first distribution channel 1410 or the second distribution channel 1420 when the first unidirectional valve 1430 is closed (turned off). Under the action of atmospheric pressure, no matter how the height and horizontal inclination of the first distribution channel 1410 or the second distribution channel 1420 change, that is, no matter how the main body shakes, the water remaining in the main body does not flow out along the first distribution channel 1410 or the second distribution channel 1420. It avoids the problem of water leakage after the main body is stopped or the pressure source 1300 stops working.

The design principle is that when both ends of a water pipe with water are open, as long as the heights of the two ends of the water pipe are different, the water in the water pipe will leak out, but if one end of the water pipe is blocked, no matter how the water pipe is placed, no matter whether the water pipe is vertical or horizontal, even if there is a height difference between the two ends of the water pipe, the water in the water pipe still does not leak out of the water pipe if the two endsare not at the same height.

It should be noted that, the first unidirectional valve 1430 or the second unidirectional valve 1440 can be selected from a soft unidirectional valve, a mechanical spring valve, an electronic valve, etc. For example, when a soft unidirectional valve is used, the first unidirectional valve 1430 or the second unidirectional valve 1440 may include a main pipe section 1431 and a flexible pipe section 1432. The inner cavity of the flexible pipe section 1432 is in communication with the inner cavity of the main pipe section 1431, and the inner pipe walls of the opposite sides of the flexible pipe section 1432 are fitted and closed with each other. The inner pipe walls on opposite sides of the flexible pipe section 1432 can be separated at the pressure levels formed when the pressure source 1300 is activated. Therefore, only the hydraulic pressure formed when the pressure source 1300 is activated can cause the soft unidirectional valve to open. Alternatively, for example, when a mechanical spring valve is used, the liquid can flow out of the mechanical spring valve only when the hydraulic pressure is greater than the elastic force of the spring in the mechanical spring valve. Or, for example, when an electronic valve is used, the first unidirectional valve 1430 or the second unidirectional valve 1440 can be automatically controlled to close when the main body is turned off or the water pump is not working.

In one embodiment, a water tank structure, including a water supply tank 1200, water outlet pipe 1370, and the water divider structure, is provided. The water supply tank 1200 has a tank top section 1310 and a tank bottom section 1320,and the tank bottom section 1320 of the water supply tank 1200 is provided with a water outlet 1360 and an air inlet 1341. The water supply tank 1200 has a water storage cavity, and the water storage cavity of the water supply tank 1200 is divided into at least two inner cavity sections 1330 from a direction of thetank top section 1310 of the water supply tank 1200 to the tank bottom section 1320 of the water supply tank 1200. The cross-sectional area of a plurality of the inner cavity sections 1330 is gradually reduced, and the cross-sectional area is perpendicular to the direction from thetank top section 1310 of the water supply tank 1200 to the tank bottom section 1320 of the water supply tank 1200. One end of the water outlet pipe 1370 is connected to the water outlet, and the pressure source 1300 of the water divider is connected to the other end of the water outlet pipe 1370.

The gradual reduction of the cross-sectional areas of the plurality of inner cavity sections 1330 of the water supply tank 1200 can specifically be expressed as the gradual reduction of the widths of different inner cavity sections 1330. That is, the width of the plurality of inner cavity sections 1330 of the water supply tank 1200 gradually decreases in the direction from the tank top section 1310 to the tank bottom section 1320. When the water supply tank 1200 is installed in the main body, comparing with adesign that keeps the overall cross-sectional area of the water supply tank 1200 the same, the design of the different cross-sectional areas in the plurality of inner cavity sections 1330 is advantageous because the water flow rate in inner cavity section 1330 with smaller cross-sectional area is faster so that it can still ensure that the water outlet speed of the water supply tank 1200 remains relatively constant even after the water level drops. The above design will not cause the water flow in the water supply tank 1200 to be significantly reduced due to the reduction of the water volume so as to improve the water outlet efficiency of the water supply tank 1200 and reduce the impact on the water outlet speed. Thereby, the water outlet speed of the water supply tank 1200 is made more uniform and stable, and the cleaning efficiency of the cleaning equipment is improved.

In one embodiment, a water outlet structure is provided on the water supply tank 1200. More precisely, the water outlet structure is provided at the tank bottom section 1320. The water outlet structure includes a blocking member 1350, a water outlet 1360, and an air inlet 1341. Thewater outlet 1360 and the air inlet 1341 both communicate with the water storage cavity. The blocking member 1350 is used to elastically block the water outlet 1360, thereby, when the water supply tank 1200 is separated from the main body, the blocking member 1350 can block the water outlet 1360 by using elastic force, so that the water inside the water supply tank 1200 cannot flow out from the water outlet 1360. When the water supply tank 1200 is assembled with the main body, a corresponding structure can be provided to overcome the elastic force of the blocking member 1350, so that the blocking member 1350 can release the blocking of the water outlet 1360. Then, the water in the water supply tank 1200 can flow out through the water outlet 1360 and be supplied to the outside of the roller brush or the main body under the driving action of the pressure source 1300.

In one embodiment, the water tank structure includes a tank cover 1340, the water outlet 1360 is opened on the tank bottom section 1320, and the tank cover 1340 is configured on the water outlet 1360. The tank cover 1340 is provided with an external port 1343 that communicates with the water outlet 1360, and the blocking member 1350 is configured on the tank cover 1340. The blocking member 1350 is used to elastically block the external port 1343, thereby blocking the water outlet 1360 further. The air inlet 1341 is opened on the tankcover 1340, and the main body is provided with a top-opening portion. The water supply tank 1200 is installed on the main body, and the top-opening portion is in abutment with the blocking member 1350 for pushing up the blocking member 1350 to open the water outlet 1360. At this time, as a structure for overcoming the elastic force of the blocking member 1350, the top opening portion can be mutually matched with the structure of the blocking member 1350, which can be structures such as pillars or bumps.

The tank cover 1340 can be assembled on the water outlet 1360 of the water supply tank 1200 through a screwed structure and be configured as the blocking member 1350 on the tank cover 1340. After screwing off the tank cover 1340, the water outlet 1360 of the water supply tank 1200 can also be used as a water inlet for replenishing water into the water storage cavity of the water supply tank 1200, so as to facilitate the water supply of the water supply tank 1200. Furthermore, there is no need to open a separate water inlet on the water supply tank 1200. Alternatively, the blocking member 1350 elastically assembled on the tank cover 1340 can also be directly designed at the position of the water outlet 1360 of the water supply tank 1200, so that the tank cover 1340 is removed, and an independent water outlet 1360 is designed in accordingly. Those skilled in the art can select a corresponding design structure according to requirements, which is not limited here.

In one embodiment, a limiting stage 1351 is provided in an external port 1343, and a limiting portion 1352 is provided on the blocking member 1350. The blocking member 1350 is elastically assembled in the external port 1343 through an elastic member. The limiting portion 1352 of the blocking member 1350 is in elastic contact with the limiting stage 1351 through the elastic force exerted by the elastic member. The limiting portion 1352 and the limiting stage 1351 elastically contact each other to block the external port 1343.

The mutually abutting surfaces of the limiting stage 1351 and the limiting portion 1352 can be planes that cooperate with each other or can be inclined surfaces that cooperate with each other. When the limiting stage 1351 and the limiting portion 1352 are in contact with each other, and the surface of the limiting stage 1351 and the surface of and the limiting portion 1352 are in contact with each other as well, the external port 1343 is well blocked, and then, in sequence, the water outlet 1360 can be blocked by blocking the external port 1343. It prevents the water in the water supply tank 1200 from flowing out through the water outlet 1360. Only when the elastic force exerted by the elastic member is overcomewill the limiting portion 1352 of the blocking member 1350 and the limiting stage 1351 be separated. The surface of the limiting stage 1351 and the surface of the limiting portion 1352 are separated from each other further so that the external port 1343 is opened. Then, the water outlet 1360 is opened, so that the water in the water supply tank 1200 flows out from the water outlet 1360.

In one embodiment, the water tank structure includes a unidirectional air valve 1342, and the unidirectional air valve 1342 is configured on the air inlet 1341. The unidirectional air valve 1342 allows air to enter the water storage cavity along the air inlet 1341. The unidirectional air valve 1342 can ensure that the air outside the water supply tank 1200 can enter the water storage cavity of the water supply tank 1200, and the water in the water storage cavity will not flow out of the water supply tank 1200 through the air inlet 1341. The unidirectional air valve 1342 can be tubular, and the bottom of the unidirectional air valve 1342 can form a V-shape. The inner pipe walls on the opposite sides of the V-shaped pipe section are closed to each other in a normal state and can be separated under the pressure formed when the pressure source 1300 is activated. Therefore, when the pressure source 1300 is continuously pumping water, the negative pressure in the water supply tank 1200 is continuously increased. When the air pressure outside the water supply tank 1200 to the unidirectional air valve 1342 is greater than the water pressure inside the water supply tank 1200 to the unidirectional air valve 1342, the outside air of the water supply tank 1200 can enter the water supply tank 1200 through the unidirectional air valve 1342 along the air inlet 1341 to supplement the air (intake) of the water supply tank 1200. When the air pressure in the water supply tank 1200 is balanced with the air pressure outside the water supply tank 1200, the unidirectional air valve 1342 can be closed under the pressure of the water pressure in the water supply tank 1200. That is, the inner pipe walls on the opposite sides of the V-shaped pipe section are closed to each other, so that the unidirectional gate valve can be closed to prevent the water in the water supply tank 1200 from flowing out of the water supply tank 1200 through the air inlet 1341.

In one embodiment, the water tank structure includes a first filter element, and the first filter element is configured at the water outlet 1360. Therefore, the water in the water supply tank 1200 can be filtered and then flow out through the water outlet 1360 to prevent the solid matter in the water supply tank 1200 from clogging the water outlet 1360 and downstream channel.

In one embodiment, the water tank structure includes an elastic snap structure 1390, and the elastic snap structure 1390 is arranged on the water supply tank 1200. The water supply tank 1200 is configured to be detachably mounted on the main body of the cleaning equipment through the elastic snap structure 1390. The elastic snap structure 1390 can more firmly connect the water supply tank 1200 and the main body when the water supply tank 1200 is assembled on the main body. In addition, the elastic snap structure 1390 generates a sound when the water supply tank 1200 is connected to the main body, and the sound can remind the user that the water supply tank 1200 has been installed on the main body, which improves user experience.

A cleaning equipment, including the main body, a wastewater tank 1100, and the water tank structure, is provided in one embodiment. The main body includes a machine body and a base, and the base is located at the bottom of the machine body. An accommodation cavity is defined by the base, and a roller brush is disposed in the accommodation cavity. A driver is provided on the main body, and the driver is connected with the roller brush. A wastewater tank 1100, configured on the main body, connects through the accommodation cavity 2300 of the base 2000, and an air outlet of the wastewater tank 1100 is also provided with a filter assembly. A suction source is configured on the main body, and the suction source generates negative pressure for sucking the dirt in the accommodation cavity 2300 into the wastewater tank 1100. For the water tank structure, the water supply tank 1200 of the water tank structure is assembled on the main body. A first distribution channel 1410 communicates with the accommodation cavity 2300 of the base, and a second distribution channel 1420 is diverting flow to the outside of the main body.

In one embodiment, the accommodation cavity 2300 is provided with a spray port 2310 connecting with the first distribution channel 1410. An included angle between an injection direction of the spray port 2310 and a radial centerline of the roller brush is an acute angle. The radial centerline is perpendicular to the central axis of the roller brush, and both ends of the roller brush are symmetrical relative to the radial centerline. At this time, the spray direction and the radial center line are at an acute angle, which can expand the spray area and make the water spray more evenly on the roller brush. If the spraying direction does not form an acute angle with the radial centerline, for example, when the spraying direction is parallel to the radial centerline, the spraying port 2310 can only spray to one point on the rolling brush when spraying along the radial centerline of the rolling brush. After the roller brush is rotated, it can only form a circle area at most, and it cannot be sprayed evenly at first.

In one embodiment, a roller brush cover 2400 is provided. The roller brush cover 2400 is assembled on the base 2000, and the roller brush cover 2400 and the base 2000 form the accommodation cavity 2300. The inner wall of the roller brush cover 2400 fits with at least a part of the bristles of the rolling brush. The bristles of the roller brush can be made of fluff or soft fiber materials. The abutment of the roller brush cover 2400 with at least a part of the bristles of the roller brush can be represented as the direct contact between the roller brush cover 2400 and the bristles of the roller brush, or expressed as a distance of 0 mm-5 mm between the roller brush cover 2400 and the bristles of the roller brush.

After the roller brush cover 2400 is attached to the bristles of the roller brush, friction and squeezing force will be formed among the roller brush, the roller brush cover 2400, and the water. The surface of the roller brush and the roller brush cover 2400 can be cleaned by the frictional pressing force among the three, so that the cleaning equipment can always keep the roller brush and the roller brush cover 2400 clean during the operation of the equipment. If the roller brush and the roller brush cover 2400 are not designed to fit together, it is difficult to keep the roller brush or the roller brush cover 2400 clean during the working process of the cleaning equipment and after the machine is self-cleaning.

In one embodiment, the cleaning equipment includes a water leakage channel 1380, and the water leakage channel 1380 communicates with the water storage cavity. The inlet of the water leakage channel 1380 is located at the lowest position of the water storage cavity. Therefore, the water remaining in the water storage cavity of the water supply tank 1200 can be discharged through the water leakage channel 1380. At this time, a matching water tank can be set on the main body, and the water discharged from the water leakage channel 1380 can be collected through the water tank.

In one of the embodiments, the cleaning equipment includes a second filter element disposed at the air outlet of the wastewater tank 1100. Therefore, the second filter element can filter the airflow in the wastewater tank 1100 and then discharge the airflowto the outside of the main body of the cleaning equipment.

In one embodiment, the cleaning equipment includes a base station 3000, a power supply 3100, and a control panel. The base 2000 and the base station 3000 are detachably assembled. The base station 3000 is provided with a first charging contact 3200, and the first charging contact 3200 is configured to connect to an external power supply. The power supply 3100 is provided on the main body, and the power supply 3100 can be a rechargeable power supply 3100. The base 2000 is provided with a second charging contact 3300, and the second charging contact 3300 is electrically connected to the power supply 3100. The first charging contact 3200 and the second charging contact 3300 are configured to be able to be electrically connected in a state in which the base 2000 is assembled to the base station 3000, so as to charge the power supply 3100 with the external power supply. The control panel is at least electrically connected to the power supply 3100, the second suction source, and the pressure source 1300. The control panel has a self-cleaning function button, and the self-cleaning function button is electrically connected to the control panel. The self-cleaning function button is configured to start the self-cleaning working mode. The self-cleaning function button starts the self-cleaning working mode, and controls the pressure source 1300 to start in the self-cleaning working mode to add water to the water supply tank 1200 and the roller brush. The rolling brush rotates to evenly disperse the water on the surface of the rolling brush, and the suction source is controlled to be activated to suck the sewage on the surface of the rolling brush into the wastewater tank 1100.

When the base 2000 of the cleaning equipment is placed on the base station 3000, the user can press the self-cleaning function button. The control panel can control the cleaning equipment to start the self-cleaning working mode through the corresponding control system. In the self-cleaning working mode of the cleaning device, the power supply 3100 can energize the second suction source, drive motor, the pressure source 1300, etc. The pressure source 1300 can control the clean water in the water supply tank 1200 to be transported to the roller brush through the water outlet pipe1370, and the driving motor drives the roller brush to rotate to execute self-cleaning of the roller brush. After the second suction source is activated, the suction of the second suction source can suck the remaining stains on the roller brush or cleaning equipment into the wastewater tank 1100. The control panel also has an interactive display module, and the interactive display module can display the charging state or other working mode states when the cleaning equipment is being charged and remind the user of the actual working condition of the current cleaning equipment.

In addition, during the charging period of the cleaning equipment, the cleaning equipment can simultaneously start the self-cleaning working mode to perform the self-cleaning operation of the roller brush. Of course, the charging function can also be selectively disabled in the self-cleaning working mode of the cleaning equipment. At the same time, when the cleaning equipment is not placed on the base station 3000, the self-cleaning working mode can also be activated to perform the self-cleaning operation of the roller brush. Whether the base 2000 and the base station 3000 are docked can be determined by detecting whether the first charging contact 3200 and the second charging contact 3300 are electrically docked, or it can be detected whether the main body and the base station 3000 are docked through a distance sensor, an infrared sensor, etc. The implemented detection manner may also be other detection manners, which will not be repeated here.

In one of the embodiments, the cleaning equipment includes a rotating device 2500 and a locking mechanism 2510. The main body includes a machine body 1000 and the base 2000. An accommodation cavity is defined by the base 2000, and a roller brush is disposed in the accommodation cavity. A driver is provided on the main body, and the driver is connected with the roller brush. The rotating device 2500 is rotatably assembled on the base 2000. The machine body 1000 is connected to the base 2000 through the rotating device 2500. The locking mechanism 2510 is provided on the rotating device 2500 and/or the base 2000. The locking mechanism 2510 is configured to lock the rotating device 2500 at a preset rotation angle.

Since the rotating device 2500 can rotate relative to the base 2000, the machine body 1000 can be indirectly rotated relative to the base 2000 through the rotation of the rotating device 2500, so that the machine body 1000 can swing forward or backward relative to the base 2000 to adjust the rotation angle of the machine body 1000 to the base 2000. The adjustment of the rotation angle of the machine body 1000 can facilitate the extension of the base 2000 into a narrow space for cleaning operations and improve the cleaning efficiency of the narrow space.

The rotating device 2500 can form a fixed axis of rotation through a structure such as a rotating shaft, so that the main body can be rotated and assembled on the base 2000 through the rotating device 2500. When the main body rotates with the rotating device 2500, the main body can be urged to achieve the effect of forward swing or backward swing. In one embodiment, a rotating groove 2520 is defined on the base 2000, and the rotating device 2500 is rotatably assembled in the rotating groove 2520 through the rotation shaft.

During the rotation of the rotating device 2500 along the rotating shaft, the locking mechanism 2510 can lock the rotating device 2500 when the rotating device 2500 rotates to the preset rotation angle. It makes the rotating device 2500 unable to continue to rotate at this rotation angle, so that the main body can be fixed relative to the base 2000 at this rotation angle. In one of the embodiments, the rotating device 2500 includes a latching member 2511 and a latching position 2512 respectively disposed between the base 2000 and the rotating device 2500. The latching member 2511 is engaged with the latching position 2512, and the locking of the rotating device 2500 at the preset rotation angle can be achieved by the mutual engaging of the latching member 2511 and the latching position 2512. The latching member 2511 can be an elastic component or indirectly assembled through the elastic component, so that the latching member 2511 can be elastically clipped and matched with the latching position 2512. The latching position 2512 can be a corresponding matching structure such as a groove, a protrusion, etc., as long as it can form an elastic limit latching connection with the elastically assembled latching member 2511.

In one embodiment, the latching position 2512 is provided on the rotating device 2500. The latching member 2511 is elastically assembled in the rotating groove 2520 through an elastic retractable member 2513. The latching member 2511 is elastically latched with the latching position 2512 through the elastic retractable member 2513. Therefore, when the rotating device 2500 is assembled and rotated in the rotating groove 2520, the rotating device 2500 can be locked by the locking mechanism 2510 at the preset rotation angle.

In one embodiment, the number of the latching members 2511 and the number of the latching positions 2512 is one. The latching member 2511 is located on the front or bottom groove wall of the rotating groove 2520, and the latching position 2512 is located at the front or bottom of the rotating device 2500. Or, the number of the latching members 2511 and the number of the latching positions 2512 is two. The two latching members 2511 are symmetrically arranged on two opposite side groove walls of the rotating groove 2520. Two of the latching positions 2512 are symmetrically arranged on two opposite sides of the rotating device 2500. In addition, the number and positions of the latching member 2511 and the latching position 2512 can be set according to requirements, which are not limited herein.

In one embodiment, the rotating mechanism 2530 is disposed between the rotating device 2500 and the main body, and the main body rotates relative to the rotating device 2500 through the rotating mechanism 2530 in a fixed axis. For example, the rotation axis of the rotating mechanism 2530 and the rotation axis of the rotating device 2500 are perpendicular to each other. At this time, the rotation of the rotating device 2500 can be responsible for driving the main body to achieve forward and backward swing motions relative to the base 2000, and the rotating mechanism 2530 can be responsible for driving the body to rotate left and right relative to the base 2000.

The rotating mechanism 2530 may adopt various structural forms. In one embodiment, the rotating mechanism 2530 includes an annular groove 2531 and an annular protrusion 2532 respectively provided on the rotating device 2500 and the main body. The annular groove 2531 and the annular protrusion 2532 are slidably assembled. The main body rotates with fixed axis relative to the rotating device 2500 through the sliding assembly of the annular groove 2531 and the annular protrusion 2532. The user can hold the main body and exert a control force on the main body, so that the annular protrusion 2532 can rotate relative to the annular groove 2531 in the circumferential direction. When the annular protrusion 2532 is circumferentially slid relative to the annular groove 2531, the main body can rotate relative to the rotating device 2500, defined as turning left and right. It is thus indirectly rotated relative to the base 2000, i.e. left and right.

In one of the embodiments, the bottom of the main body is provided with a detachable bottom cover 2533. The bottom cover 2533 and the bottom of the main body are respectively provided with a part of the annular groove 2531 or a part of the annular protrusion 2532. The bottom cover 2533 and the bottom of the main body are assembled to form the annular groove 2531 or the annular protrusion 2532. The separation of the bottom cover 2533 relative to the main body can crack the annular groove 2531 or the annular protrusion 2532. The splicing of the bottom cover 2533 relative to the main body can form a complete annular groove 2531 or an annular protrusion 2532. Therefore, when the bottom cover 2533 is separated from the main body, the assembly of the main body and the annular groove 2531 and the annular protrusion 2532 on the rotating device 2500 can be facilitated.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, all should be regarded as the scope described in this specification.
