Referring to FIGS. 1-11, an electric mop according to an exemplary embodiment of the present disclosure includes a handle 1, a mopping member 2 connected to the handle 1. The mopping member 2 includes a driving member 3 and a cleaning member 4 connected to an output of the driving member 3. The cleaning member 4 includes a first cleaning portion 41 and a second cleaning portion 42 parallel to the first cleaning portion 41. The driving member includes:

A motor 30 includes an output shaft 30a connected to a driving bevel gear 31. Control components of the motor 30 are generally installed within the handle 1 and wire passes from the handle 1 into the mopping member 2 to electrically connect to the motor 30.

A reversing gear 32 includes a driven bevel gear portion 320 and a driven cylindrical gear portion 321 coaxially fixed with each other. The driven bevel gear portion 320 is meshed with the driving bevel gear 31 so that the reversing gear 32 is formed a right-angle transmission relationship with the driving bevel gear 31. A state of the mopping member 2 attached to the ground is taken as a horizontal direction reference when the electric mop is used. The rotation of the motor 30 in a vertical plane (perpendicular to a horizontal plane) is transformed into the horizontal plane by right-angle drive and then the horizontal rotation is transmitted out by the driven cylindrical gear portion 321.

A cylindrical driving gear group 35a includes a first cylindrical gear 35 connected to the first cleaning portion 41 and a second cylindrical gear 36 connected to the second cleaning portion 42. The first and second cleaning portions 41, 42 are respectively positioned on the left side and the right side of the mopping member 2 and the two parts are horizontally farmed to each other. In this way. The overlap of both the first and second cleaning portions can ensure a large cleaning area and a single smaller cleaning portion can clean up a dead angle.

A first cylindrical gear group 33 is meshed with a side of the driven cylindrical gear portion 321, with its output meshed with the first cylindrical driving gear 35, and a second cylindrical gear group 34 is meshed with the other side of the driven cylindrical gear portion 321 with its output meshed with the second cylindrical driving gear 36. It can ensure that the cleaning member 4 is ultimately driven to rotate in a direction of the horizontal plane to realize the cleaning operation by the transmission of the first and second cylindrical gear groups 33, 34.

In the present embodiment of the disclosure,

The difference between the number of cylindrical gears of the first cylindrical gear group 33 and the second cylindrical gear group 34 is singular. Referring to FIG. 4, there is one difference in the number of cylindrical gears used for sequential transmission in the two gear groups, thereby the rotation direction of the first cleaning portion 41 and the second cleaning portion 42 is opposite. Viewed from the top, one rotation direction is clockwise and the other rotation direction is counterclockwise In this way, force respectively applied on the two cleaning portions can offset each other to a certain extent for users to keep balance and steadily control a moving direction of the electric mop.

In some exemplary embodiments of the present disclosure, each of the first cylindrical gear group 33 and the second cylindrical, gear group 34 includes a rack wheel 300 and a pinion 301 coaxially fixed with the rack wheel 300 (seen in FIG. 11). That is to say, the rack wheel 300 and the pinion 301 are in-line gears. Both the rack wheel 300 and the pinion 301 are cylindrical gears. The rack wheel 300 is acted as a transmission input, and the pinion 301 is acted as a transmission output. The in-line gears in a middle portion of the gear groups is taken as an example to describe the transmission input and the transmission output in detail: power is first transmitted from the motor 30 to the cleaning member 4, the rack wheel 300 in the middle portion of one gear group meshes with the pinion 301 of a previous in-line gear (closer to the motor 30), and the pinion 301 of the same gear group meshes with a rack wheel 300 of a next in-line gear. That is, for a same in-line gear self, its rack wheel 300 is as an introduction power, and its pinion 301 is as an output power. By means of the rack wheel 300 and the pinion 301 of a same in-line gear misaligned in height, it is possible to reduce an area occupied and avoid the mopping member 2 being too large.

In some exemplary embodiments of the present disclosure, the mopping member 2 includes a housing 2a which includes an oval cover 20, an oval base 21 clasped with the cover 20 and a receiving chamber 200 formed between the cover 20 and the base 21. The receiving chamber 200 includes a box 202 for receiving the driving member 3 therein. The box 202 includes an upper plate 302 formed on the top thereof and a lower plate 303 formed opposite to the upper plate 302. The motor 30 is horizontally received in a middle portion of the box 202 along the Y-axis direction, and both the cover 20 and the base 21 are curved outward at an installation of the motor 30 in the box 202, thereby a partial arch can allow the motor 30 be smoothly installed and avoid the increase of the overall thickness of the housing 2a. The first and second cylindrical gear groups 33, 34 are respectively positioned on the left side and the right side of the reversing gear 32 along the X-axis direction. The first cylindrical driving gear 35 is coordinated with the first cleaning portion 41 via a polygonal shaft lever 37 to engage with a shaft sleeve 43 of the first cleaning portion 41, and the second cylindrical driving gear 36 is also coordinated with the second cleaning portion 42 via another polygonal shaft lever 37 to engage with another shaft sleeve 43 of the second cleaning portion 42. The polygonal shaft lever 37 and a corresponding shaft sleeve 43 are locked with each other by bolts (not shown). Referring to FIG. 2 and FIG. 3, a cross sectional of each of the polygonal shaft lever 37 and the shaft sleeve 43 is hexagonal. The shaft lever 37 passes through the lower plate 303 and a through-hole 210 of the base 21 and then inserts into a sleeve so that the rotation of the cylindrical driving gear group 35a can be transmitted to the cleaning member 4 via the engagement of the polygonal structure, and then a bolt (not shown is used to screw the shaft lever 37 from the inside of the shaft sleeve 43 into a screw hole 370 of the shaft lever 37 to fix the two parts together. A bearing 305 is arranged on the shaft lever 37 at a position corresponding to the lower plate 303. The lower plate 303 includes a stepped subsidence slot (not labeled) for the bearing 305 sleeving on the shaft lever 37 and then being received in the stepped subsidence slot. In this way, the bearing 305 is provided for reducing the friction between the shaft lever 37 and the box 202 when rotation of the shaft lever 37, and also ensuring the rotation stability of the shaft lever 37.

In some exemplary embodiments of the present disclosure, referring to FIGS. 4-6, each of the first and second cylindrical driving gears 35, 36 includes a first horizontal ring 38 extending upward from a corresponding upper surface 350, 360 thereof, with an equal-altitude gap 304 formed between the first horizontal ring 38 and the upper plate 302. A second horizontal ring 39 is extended downward from a middle portion of the upper plate 302 and corresponding to the first and second cylindrical driving gears 35, 36, with a same equal-altitude gap 304 formed between the second horizontal ring 39 and the corresponding upper surface 350, 360 of the first and second cylindrical driving gears 35, 36. A center of the first horizontal ring 38 corresponds to that of the second horizontal ring 39, but the radius of the first and second horizontal rings 38, 39 is different to avoid hedging therebetween.

During operation of the electric mop, the cylindrical driving gear group 35a can produce a fluctuation along the Z axis under a centrifugal force, such kind of fluctuation can affect the attachment of the cleaning member 4 and the ground so that the electric mop can't thoroughly clean the ground. The first and second horizontal rings 38, 39 are provided for effectively reducing an influence of the centrifugal force on the cylindrical driving gear group 35a. The cylindrical driving gear group 35a is kept in a horizontal position by the first horizontal ring 38 and the second horizontal ring 39 respectively matching with the upper plate 302, the upper surfaces 350, 360 of the first and second cylindrical driving gears 35, 36 to ensure the cleaning member 4 closely attached to the ground, respectively. It is taken the first horizontal ring 38 as an example, the equal-altitude gap 304 is provided for preventing the first horizontal ring 38 from interfering with the rotation of the second cylindrical drive gear 36. It can be noted that the term “equal height” means that the height between a top edge of the first horizontal ring 38 and the upper plate 302 is equal, thereby the fluctuation of the second cylindrical driving gear 36 can be controlled within an approximate horizontal range. When the fluctuation of the second cylindrical driving gear 36 in the direction of the Z axis reaches to a certain extent, the top edge of the first horizontal ring 38 can be touched on the upper plate 302 to avoid further fluctuation.

Referring to FIGS. 9-10, in some exemplary embodiments of the present disclosure, a handle bottom portion 1a of the handle 1 is movably connected to the mopping member 2 and includes a pair of clamping portions 6 horizontally opposite to each other. A groove (not labeled) is formed between the pair of clamping portions 6. A ballhead 5 is formed in the groove and rotatable connected to the pair of clamping portions 6 by a horizontal shaft 60 of the clamping portion 6 inserted into a corresponding horizontal shaft hole 63 of the ballhead 5. The mopping member 2 includes a pair of supporting portions 7 longitudinally opposite to each other. The pair of supporting portions 7 is rotatably connected to the ballhead 5 by a longitudinal shaft 70 of the supporting portion 7 inserted into a corresponding longitudinal shaft hole 73. Specifically, the horizontal shaft 60 includes a first shaft body 61 and the longitudinal shaft 70 includes a second shaft body 71. The first shaft body 61 is inserted into the horizontal shaft hole 63 and includes a first annular flange 62 at a distal end thereof, and the second shaft body 71 is inserted into the longitudinal shaft hole 73 and includes a second annular flange 72 at a distal end thereof. The first and second annular flanges 62, 72 are provided for avoiding the first shaft body 61 from separating from the horizontal shaft hole 63 and the second shaft body 71 from separating from the longitudinal shaft hole 73. In this way, a horizontal rotation and a longitudinal rotation between the handle 1 and the flopping member 2 is obtained so that users can flexibly operate the electric mop in the usage process.

Referring to FIGS. 7-8, in some exemplary embodiments of the present disclosure, the handle 1 is a telescopic structure and includes a fixing post 10 and a moving post 11 sleeved onto the fixing post 10 from a top 10a of the fixing post 10. The top 10a of the fixing post 10 includes a locking member 100 for controlling a movable position of the moving post 11. When the locking member 100 is opened, the moving post 11 can move along an axis of the fixing post 10 to adjust a proper length of the handle 1. The locking member 100 is closed to limit the position of the moving post 11 after its adjustment is completed. In general, common clasps, bolts, etc., may be used to accomplish the above function, but it is inconvenient to operate the electric mop, so the following solution is preferred:

The locking member 100 includes:

An inner sleeve 12 is sleeved onto the top 10a of the fixing post 10 and positioned between the moving post 11 and the fixing post 10. The inner sleeve 12 includes a slot 17 and a limiting member 14 movably formed on the slot 17.

A plurality of adjusting recesses 110 is arranged along an axial direction of an outer surface of the moving post 11 and combined with the slot 17 to form a receiving room 110a for receiving the limiting member 14 therein.

A pushing plate 15 is installed between the inner sleeve 12 and the fixing post 10, and a cavity 13 is formed between the inner sleeve 12 and the fixing post 10 for the pushing plate 15 axially sliding in the cavity 13 to realize engagement or disengagement of the pushing plate 15 and the slot 17. In a misalignment state, the limiting member 14 is driven by the moving post 11 to pass through the slot 17 and slide into the cavity 13. While in a closed state, the limiting member 14 is driven by the pushing plate 15 to pass through the slot 17 and then fall into the receiving room 110a. In order to facilitate applying force, the pushing plate 15 includes an operating key 150 exposed out of the handle 1. The operating key 150 is curved upward at a middle portion thereof so that both its front end surface (not labeled) and its back end surface (not labeled) are inclined. Force is applied on the pushing plate 15 until it is staggered from the slot 17, thereby the locking member 100 is opened. Which is an accidental operation, but a normal state of the locking member 100 is closed. In order to maintain the pushing plate 15 in a normal position closed with the slot 17, a spring 16, as a resetting member, is provided. One end of the spring 16 is abutted against the pushing plate 15 and the other end of the spring 16 is resisted against a wall surface (not labeled) of the fixing post 10. The spring 16 is temporarily compressed when the locking member 100 is opened, while the pushing plate 15 is kept in a position of closing the slot 17 by an elastic action of the spring 16 after the operation is completed.

The operation principle of the locking member 1110 is shown the following:

At an opening step, the pushing plate 15 is operated to stagger from the slot 17 and then the mooring post 11 is operated to begin telescoping. In this process, the limiting member 14 is separated from a corresponding adjusting recess 110 by passing through the slot 17 and finally enters the cavity 13. The moving post 11 can be freely telescoped without the interference of the limiting member 14.

At a closed step, the moving post 11 is adjusted to reach a proper position and the pushing plate 15 is reset to move in the cavity 13. At this time, the limiting member 14 is again pushed into the receiving room 110a under the pushing plate 15 resetting in the cavity 13, thereby the moving post 11 is limited under the interference of limiting member 14.

In order to smoothly complete to operate the limiting member 14, the following optimized settings are made: the limiting member 14 is a cylindrical bar, and the adjusting recess 110 includes a bottom wall 111 and a pair of sidewall 112 respectively connected to two opposite ends of the bottom wall 111. An obtuse angle is formed between the bottom wall 111 and each sidewall 112, and a slant surface 15b is formed at a distal end 15a of the pushing plate 15 and gradually inclined downward from the distal end 15a of the pushing plate 15. Resistance applied on the limiting member 14 is reduced hen it is disengaged or engaged with the slot 17 under a guide of the slant surface 15b and the cylindrical structure of the limiting member 14.
