DETAILED DESCRIPTION OF THE EMBODIMENTS

The following are specific embodiments of the present disclosure, and further describes technical solutions of the present disclosure in conjunction with the accompanying drawings, but the present disclosure is not limited to these embodiments.

Embodiment 1

As shown in FIGS. 1 to 3, a support on a cleaning device includes trays 1 where water outlet channels 2 are provided. A height difference is formed between two sides of each of the water outlet channels 2, so that when flowing in a direction from high to low, a fluid used for cleaning in each of the trays 1 can cross the corresponding water outlet channel 2 and is kept from flowing out via the corresponding water outlet channel 2, and when the fluid in each of the trays 1 flows in a direction from low to high, the fluid can flow out via the corresponding water outlet channel 2. The height difference formed between the two sides of each of the water outlet channels 2 is used for combining washing and thorough scraping of a corresponding mop cloth of a floor mopping machine by the corresponding tray 1 with discharging of the corresponding fluid, when each of the fluids is driven by a corresponding rotary disc of the floor mopping machine to flow in the direction from high to low, it crosses the corresponding water outlet channel 2 to complete the washing of the corresponding mop cloth of the floor mopping machine while not flowing out via the corresponding water outlet channel 2, after washing is completed, each of the fluids is driven to flow from low to high and falls into the corresponding water outlet channel 2, and the corresponding mop cloth is thoroughly scraped by a high end 3 formed by the corresponding height difference.

Positions of each of the trays 1 on two sides of the corresponding water outlet channel 2 respectively serve as a high end 3 and a low end 4, and an inclined guiding surface 5 is formed at each of the high ends 3 and makes a height of each of the high ends 3 gradually increase in a direction of getting close to the corresponding water outlet channel 2. Each of the guiding surfaces 5 is a cambered surface or an inclined surface.

A water storage space can be formed in each of the guiding surfaces 5. The size of each of the water storage spaces can be controlled by setting an angle and length of the corresponding guiding surface 5. Each of the water storage spaces can also be used as a water injection opening. An effect of quantifying water required can further be achieved. Each of the guiding surfaces 5 further makes the flowing direction form an upward angle so as to make the corresponding fluid better directly flow from the corresponding high end 3 to the corresponding low end 4 across the corresponding water outlet channel 2. A scraping part rubbing against a corresponding wiper when the corresponding wiper is washed is formed at an upper end of each of the guiding surfaces 5, and a thorough scraping part capable of thoroughly scraping a corresponding wiper when the corresponding wiper is thoroughly scraped is formed on a side portion of each of the guiding surfaces. During washing, the upper end of each of the guiding surfaces scraps dirt in the corresponding wiper with the help of clear water to realize a cleaning effect. Each of the thorough scraping parts squeezes the corresponding wiper when needing to thoroughly scraping it, so as to squeeze out water in the wiper to realize thorough scraping.

A height of a side of each of the low ends 4 close to the corresponding water outlet channel 2 is greater than a height of a side of each of the low ends 4 away from the corresponding water outlet channel 2. A water storage space is also formed on one side of each of the low ends 4. Each of the low ends 4 is provided with an arc-shaped water storage surface, and each of the water storage surfaces makes the height of the side of the corresponding low end 4 close to the corresponding water outlet channel 2 greater than the height of the side of the corresponding low end 4 away from the corresponding water outlet channel 2. The arc-shaped water storage surfaces are conducive to storage of the fluids, which facilitates washing of the mop cloths. As another implementation, a side of each of the low ends 4 close to the corresponding water outlet channel 2 can further be provided with a step, and each of the steps makes a water storage space formed in the corresponding low end 4.

As shown in FIG. 3, each of the trays 1 is circular, and the corresponding water outlet channel 2 is outwards diverged from a circle center of the tray 1. Scraping-off pieces 6 are further provided in each of the trays 1. The scraping-off pieces 6 are protrusions provided on a plane of each of the trays 1 and used for being in contact with the corresponding mop cloth to scrape off dirt on the corresponding mop cloth. An axis of each of the trays 1 is further provided with a positioning base facilitating positioning of the cleaning device. The positioning bases are used for being in butt joint with the floor mopping machine. There are two trays 1, which facilitate butt joint of the double-rotary-disc floor mopping machine.

The support of the embodiment is applied to the cleaning device. The cleaning device includes a base. The support is provided in the base. A sewage cavity is provided in the base. The water outlet channels 2 communicate with the sewage cavity.

The working process of the present disclosure is as follows. When washing is needed, clear water is directly poured into the trays 1 and stays in the trays, and the guiding surfaces 5 at the high ends 3 and water storage surfaces at the low ends form water storage areas of the trays. The floor mopping machine is in butt joint with the trays 1 and is turned on, and the floor mopping machine starts to forward rotate and drives the clear water in the trays 1 to flow in the direction from high to low. Owing to existence of the height differences, the clear water crosses the water outlet channels 2 via the high ends 3 when driven by the floor mopping machine to forwards rotate, so that the clear water hardly flows out from the water outlet channels 2 when forwards rotating. Moreover, owning to the scrapping parts formed at the high ends squeezing and rubbing against the mop cloths and the scrapping-off effect of the scrapping-off pieces 6 in the trays, stains on the mop cloths are flushed, squeezed and scrapped off to complete washing of the mop cloths. After washing is completed, the floor mopping machine backwards rotates, and at this moment, sewage after washing the mop clothes in the water storage areas backwards rotates and flows in the direction from the low ends 4 to the high ends 3. Since the high ends 3 are higher than the low ends 4, the sewage flows out along the water outlet channels 2 under the blocking effect of the high ends 3. In addition, owning to the scrapping effect of the thorough scrapping parts at the high ends 3 on the mop cloths, sewage on the mop cloths can further be thoroughly scrapped, thus completing the actions of thoroughly scrapping the mop cloths and discharging the sewage.

Embodiment 2

As shown in FIG. 4, the embodiment has basically the same principle and structure as Embodiment 1, and the differences lie in that connecting pieces are provided between the high ends 3 and the low ends 4, and the water outlet channels 2 are water outlet holes provided in the connecting pieces. The connecting pieces play a role of improving the strength of the trays 1 and can be integrally molded in the molding process, without being cut to form the water outlet channels 2 and disconnect the trays 1 to reduce the strength. The water outlet holes are provided in the side portions of the connecting pieces, which facilitates outflow of the sewage and can also realize the functions of the water outlet channels 2.

Embodiment 3

As shown in FIGS. 5 to 11, the embodiment has basically the same principle and structure as Embodiment 1, and the differences lie in that a water inflow tank 7 is provided on the base and is a quantitative water inflow tank, and water from the water inflow tank 7 flows onto a tray. The quantitative water inflow tank is used for realizing quantitative water inflow, and meanwhile, cleaning solution electrolytic water and the like can further be added into the water inflow tank 7 to play a role of enhancing the cleaning effect. The water inflow tank 7 communicating with the tray 1 is provided on the base. A water tank partition 2-4 is provided in the water inflow tank 7 and separates the water inflow tank 7 into a water storage cavity 31 and a quantitative water cavity 32 that communicate with each other. The quantitative water cavity 32 is internally provided with a valve assembly 2-5 capable of closing an outlet of the quantitative water cavity 32 when the water storage cavity 31 communicates with the quantitative water cavity 32, and when the outlet of the quantitative water cavity 32 is opened, a connecting channel between the water storage cavity and the quantitative water cavity 32 is closed.

The valve assembly 2-5 includes an upper valve core 51 and a lower valve core 52. The upper valve core 51 is used for opening and closing the connecting channel between the water storage cavity 31 and the quantitative water cavity 32. An ejector core support 53 is provided on the water tank partition 2-4. An ejector core connecting rod 54 sliding up and down is provided on the ejector core support 53. The two ends of the ejector core connecting rods 54 penetrate through the ejector core support 53. The upper valve core 51 and the lower valve core 52 are located at the two ends of the ejector core connecting rod 54. When the ejector core connecting rod 54 is ejected up, the upper valve core 51 can seal a connecting opening, and when the ejector core connecting rod 54 is dropped down, the lower valve core 52 can seal a water outlet.

The lower valve core 52 is used for opening and closing the outlet of the quantitative water cavity 32. An elastic assembly 2-6 enabling the lower valve core 52 to always have the movement trend to close the outlet of the quantitative water cavity 32 is provided between the upper valve core 51 and the lower valve core 52. The elastic assembly 2-6 includes a second spring 61 provided between the ejector core connecting rod 54 and a connecting support. After washing is completed, the floor mopping machine is taken down, so that the end of a connecting rod structure 9 that downwards pressed by the floor mopping machine cocks up, and the other end falls, thus making the lower valve core 52 lose support force. Resilience force of the squeezed second spring 61 enables the lower valve core 52 to quickly return to an original position, so that the lower valve core 52 seals the water outlet to stop water from flowing out. Meanwhile, the upper valve core 51 downwards moves, and the connecting opening between the water storage cavity 31 and the quantitative water cavity 32 is opened, so that water in the water storage cavity 31 is introduced into the quantitative water cavity 32 to quantitative water store water of next washing. The second spring 61 always has certain elastic force for downwards pressing the lower valve core 52, thus improving leakproofness between a water outflow ejector core and the water outlet and preventing the water inflow tank 7 from leaking water.

A connecting rod structure 9 driving the valve assembly 2-5 to act is provided on the base. The connecting rod structure 9 includes a first connecting rod 91 provided below the tray 2, and the first connecting rod 91 is hinged to the base. One end of the first connecting rod 91 is hinged to a second connecting rod 92, and the second connecting rod 92 penetrates through the tray 2 to be connected with the valve assembly 2-5. The other end of the first connecting rod 91 is hinged to a third connecting rod 93, and the third connecting rod 93 penetrates through the tray 2 to form a control end. The first connecting rod 91 is located below the tray 2, so that only the control end is visible above tray 2, which is more attractive, and the first connecting rod 91 is hinged to the second connecting rod 92 and the third connecting rod, respectively. The second connecting rod 92 and the third connecting rod 93 can always move up and down in the direction perpendicular to the tray 2 through hinged structures, which ensures that the floor mopping machine is fixed to the same force bearing point when being downwards pressed, and can ensure that the valve assembly 2-5 periodically acts on the same force bearing point.

A hinged shaft 10 is provided on the first connecting rod 91. A hinged hole 11 of the second connecting rod 92 sleeves the hinged shaft 10. The inner diameter of the hinged hole 11 is greater than the outer diameter of the hinged shaft 10. Swing of the first connecting rod 91 makes the end of the first connecting rod 91 to move in an arc shape, thus forming displacements in an up-down direction and a left-right direction. However, the second connecting rod 92 only has the trend to move on the tray 2 in the up-down direction, and thus after a clearance is formed between the hinged hole 11 and the hinged shaft 10, the displacement in the left-right direction can be offset by the clearance. Similarly, a hinged relationship between the first connecting rod 91 and the third connecting rod 93 also forms clearance fit, so that the third connecting rod 93 only acts in the up-down direction when the first connecting rod 91 swings.

A shock-proof module is provided at the control end of the third connecting rod 93 and includes a buffer block 12. The floor mopping machine can generate vibration in the washing process. Since the valve assembly 2-5 is controlled by pressing the connecting rod structure 9 through the floor mopping machine, the vibration of the floor mopping machine can be transferred to the valve assembly 2-5 through the connecting rod structure 9. However, the provision of the shock-proof module can reduce the vibration to prevent looseness of the valve assembly 2-5 or the influence on the control precision of the valve assembly 2-5, thereby preventing water leakage of the valve assembly 2-5.

The buffer block 12 is detachably connected to the control end, and is flexible glue or silica gel or rubber.

A cleaning solution storing cavity 2-7 is further provided in the water inflow tank 7. A cleaning solution outlet 13 communicating with the quantitative water cavity 32 is provided below the cleaning solution storing cavity 2-7. A cleaning solution valve 8 is provided at the cleaning solution outlet 13 and synchronously acts with the valve assembly 2-5, and when the outlet of the quantitative water cavity 32 is opened, the cleaning solution valve 8 is synchronously opened.

The cleaning solution valve 8 includes a valve core mounting rack 81, a cleaning solution valve core 82 and a cleaning solution valve rod 83. The cleaning solution valve rod 83 is provided on the valve core mounting rack 81 and slides up and down on the valve core mounting rack 81. The cleaning solution valve core 82 is provided at the bottom end of the cleaning solution valve rod 83, and used for closing the cleaning solution outlet 13. A first spring 84 is provided between the valve core mounting rack 81 and the valve core, and makes the cleaning solution valve 8 always have the trend to be closed. The first spring 84 making the cleaning solution valve 8 always have the trend to be closed enables leakproofness between the cleaning solution valve core 82 and the cleaning solution outlet 13 to be improved, so as to prevent a cleaning solution in the cleaning solution storing cavity 2-7 from leaking into the quantitative water cavity 32.

A connecting piece 14 is provided between the cleaning solution valve 8 and the valve assembly 2-5, and the cleaning solution valve 8 and the valve assembly 2-5 synchronously move after connected through the connecting piece 14. In the embodiment, the connecting piece 14 can be a connecting rod. The two ends of the connecting rod are respectively connected with the upper valve core 51 and the cleaning solution valve core 82 and used for driving the upper valve core 51 and the cleaning solution valve core 82 to synchronously move. In the washing process, when the valve assembly 2-5 is pressed by the connecting rod structure 9, the valve assembly 2-5 is opened. The connecting piece 14 enables the cleaning solution valve 8 to be opened while the valve assembly 2-5 is opened. The cleaning solution in a cleaning solution containing cavity is introduced into the quantitative water cavity 32, thus improving the effect of washing the floor mopping machine.

The working principle is as follows. When washing is conducted, the floor mopping machine is placed on the tray 2, and downwards presses the third connecting rod 93 through its own weight, so that the second connecting rod 92 at the other end upwards moves. When the lower valve core 52 is ejected up, the ejector core connecting rod 54 upwards moves to drive the upper valve core 51 to upwards move till the upper valve core 51 completely seals the connecting opening between the water storage cavity 31 and the quantitative water cavity 32, and at this time, the connecting channel between the quantitative water cavity 32 and the cleaning solution storing cavity 2-7 and the water outlet of the quantitative water cavity 32 are simultaneously opened, so that the cleaning solution flows into the quantitative water cavity 32 and water in the quantitative water cavity 32 flows into the tray 2 to wash the floor mopping machine. After washing is completed, the floor mopping machine is taken down, so that one end of the third connecting rod 93 cocks up, and the second connecting rod falls, thus making the lower valve core 52 lose support force. Resilience force of the squeezed second spring 61 enables the lower valve core 52 to quickly return to the original position, so that the lower valve core 52 closes the water outlet. Meanwhile, the connecting piece 14 drives the cleaning solution valve core 82 to close the connecting channel between the quantitative water cavity 32 and the cleaning solution storing cavity. Meanwhile, the upper valve core 51 upwards moves, and the connecting opening between the water storage cavity 31 and the quantitative water cavity 32 is opened, so that water in the water storage cavity is introduced into the quantitative water cavity for quantitative water storage of next washing.

According to the present disclosure, by providing the water storage cavity 31, the quantitative water cavity 32 and the valve assembly 2-5, when the floor mopping machine is washed, the valve assembly 2-5 can open the outlet of the quantitative water cavity 32 and close the connecting channel between the water storage cavity and the quantitative water cavity 32, so that the floor mopping machine can only use the water in the quantitative water cavity 32 when washed, thus quantifying the washing water, reducing waste of water resources and saving water. After washing is completed, the valve assembly 2-5 can close the outlet of the quantitative water cavity 32 and open the connecting channel between the water storage cavity and the quantitative water cavity 32, so that the water in the water storage cavity 31 flows into the quantitative water cavity 32 for quantitative water storage of next washing.

Embodiment 4

Embodiment 5

As shown in FIG. 7, in the embodiment, the trays 1 are each in a plate shape. Water outlet channels 2 are provided on the trays 1. A height difference is formed between two sides of each of the water outlet channels 2, so that when flowing in a direction from high to low, a fluid used for cleaning in each of the trays 1 can cross the corresponding water outlet channel 2 and is kept from flowing out via the corresponding water outlet channel 2, and when the fluid in each of the trays 1 flows in a direction from low to high, the fluid can flow out via the corresponding water outlet channel 2. The height difference formed between the two sides of each of the water outlet channels 2 is used for combining washing and thorough scraping of a corresponding mop cloth of a floor mopping machine by the corresponding tray 1 with discharging of the corresponding fluid, when each of the fluids is driven by a corresponding rotary disc of the floor mopping machine to flow in the direction from high to low, it crosses the corresponding water outlet channel 2 to complete the washing of the corresponding mop cloth of the floor mopping machine while not flowing out via the corresponding water outlet channel 2, after washing is completed, each of the fluids is driven to flow from low to high and falls into the corresponding water outlet channel 2, and the corresponding mop cloth is thoroughly scraped by a high end 3 formed by the corresponding height difference.

Positions of each of the trays 1 on two sides of the corresponding water outlet channel 2 respectively serve as a high end 3 and a low end 4. During washing, when sliding from the corresponding high end to the corresponding low end, each of the mop cloths can drive the corresponding fluid to flow from the corresponding high end to the corresponding low end across the corresponding water outlet channel to be washed, and a scrapping part at the corresponding high end is used for scrapping off dirt. When thoroughly scrapped, each of the mop cloths slides from the corresponding low end to the corresponding high end and can drive the corresponding fluid to flow out along the corresponding water outlet channel, and a thorough scrapping part at the corresponding high end is used for thoroughly scrapping the sewage on the corresponding mop cloth.

The specific embodiments described herein merely illustrate the spirit of the present disclosure. A person skilled in the technical field to which the present disclosure belongs can make various modifications or supplements on the described specific embodiments or substitute them in a similar way, without departing from the spirit of the present disclosure or exceeding the scope defined by the appended claims.
