[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] At present, the brushes of floor scrubbers on the market generally use disc brushes or cylindrical roller brushes. Their floor scrubbing action rotates around a central axis, which can easily cause the central axis to be entangled with hair and other soft, long garbage, making it difficult to clean. In addition, during the floor scrubbing process, the floor is scrubbed on the way forward by the floor scrubber, and some stubborn stains cannot be cleaned.

[0036] In order to alleviate the above technical problems, the present invention proposes a floor scrubber, which includes a main body assembly 10 and a water tank assembly 20. The cleaning brush assembly 12 of the main body assembly 10 rubs against the ground to clean the ground. The cleaning brush body 124 can move in a first direction under the action of a driving mechanism 120. The first direction forms an angle with the moving direction of the sweeper, so that the cleaning brush body 124 moves in the first direction while moving forward, and the same position on the ground is scrubbed multiple times in multiple directions to achieve a better cleaning effect.

[0037] The floor scrubber provided in the embodiment of the present invention is now described.

[0038] Please also read Figures 1 to 4 The floor scrubber includes a main assembly 10 and a water tank assembly 20 connected to the main assembly 10. The main assembly 10 includes a base 11 and a cleaning brush assembly 12. The cleaning brush assembly 12 includes a driving mechanism 120 and a cleaning brush body 124 arranged on the base 11. The driving mechanism 120 is used to drive the cleaning brush body 124 to move in at least a first direction. The moving direction of the main assembly 10 is a second direction. The first direction and the second direction are arranged at an angle.

[0039] The host assembly 10 is the main part of the floor scrubber, which realizes the functions of moving and cleaning the floor scrubber. The host assembly 10 includes a base 11 and a cleaning brush assembly 12, and the cleaning brush assembly 12 is installed on the base 11. The base 11 is the shell part of the host assembly 10, and other electrical components of the host assembly 10 are installed on the base 11. The cleaning brush assembly 12 includes a driving mechanism 120 and a cleaning brush body 124. The driving mechanism 120 is a power mechanism that transmits power to the cleaning brush body 124, so that the cleaning brush body 124 moves at least in the first direction. One end of the cleaning brush body 124 is directly or indirectly connected to the driving mechanism 120, and the side of the cleaning brush body 124 with bristles contacts the ground, and the ground is cleaned by the relative movement between the cleaning brush body 124 and the ground. When the host assembly 10 moves along the second direction, the cleaning brush body 124 moves along the second direction, and at the same time, the driving mechanism 120 can drive the cleaning brush body 124 to move in the first direction. That is, the cleaning brush body 124 can move in the first direction and the second direction at the same time, thereby scrubbing the floor in multiple directions, so that the floor scrubber can remove floor stains more effectively.

[0040] The first direction and the second direction are arranged at an angle, the first direction is the forward direction of the floor scrubber, and both the first direction and the second direction are horizontal directions.

[0041] The water tank assembly 20 is connected to the main assembly 10. The water tank assembly 20 is mainly used to provide clean water, and cooperates with the cleaning brush body 124 to scrub the ground, which can not only clean dust, but also clean with water, and the cleaning effect is better.

[0042] The floor scrubber in the above embodiment includes a main unit assembly 10 and a water tank assembly 20. The main unit assembly 10 includes a base 11 and a cleaning brush assembly 12. The cleaning brush body 124 can move in a first direction under the driving action of the driving mechanism 120, forming an angle with the moving direction of the floor scrubber. In this way, the cleaning brush body 124 can move in the left and right directions while moving forward, and scrub the same position on the ground multiple times, thereby improving the cleaning intensity of the ground.

[0043] In some embodiments of the present invention, see Figure 3 The main engine assembly 10 further includes a plurality of rollers and a motor. The motor drives the rollers to rotate, thereby realizing the movement of the floor scrubber in the second direction, that is, realizing the forward and backward movement of the floor scrubber.

[0044] In some embodiments of the present invention, the first direction and the second direction are perpendicular to each other. The first direction is the front-to-back direction, and the second direction is the left-to-right direction. Therefore, when the floor scrubber moves forward, the cleaning brush body 124 can move left and right at the same time, so that the cleaning brush body 124 can scrub the floor more thoroughly. When the first direction and the second direction are perpendicular, the cleaning force of the cleaning brush body 124 on the left and right sides of the scrubbing area is similar, avoiding the situation where one side is not cleaned thoroughly.

[0045] In the embodiment of the present invention, the driving mechanism 120 drives the cleaning brush body 124 to reciprocate in the first direction, that is, the cleaning brush body 124 reciprocates in the positive direction and the reverse direction of the first direction. In this way, the cleaning brush body 124 can reciprocate to improve the cleaning force.

[0046] In some embodiments of the present invention, see Figure 4 The driving mechanism 120 includes a driving member 121 capable of outputting a rotational motion, a first connecting rod 122 driven to rotate by the driving member 121 , and a second connecting rod 123 rotatably connected to the first connecting rod 122 , and the second connecting rod 123 is connected to a cleaning brush body 124 .

[0047] The driving member 121 is a power component that can output rotational motion. The motion output end of the driving member 121 is fixedly connected to one end of the first connecting rod 122, and the other end of the first connecting rod 122 is rotationally connected to the second connecting rod 123, and the second connecting rod 123 is connected to the cleaning brush body 124. When the driving member 121 is working, the first connecting rod 122 and the second connecting rod 123 both rotate, and the end of the second connecting rod 123 away from the first connecting rod 122 slides back and forth in the first direction, thereby driving the cleaning brush body 124 to slide back and forth in the first direction. Specifically, the first connecting rod 122, the second connecting rod 123 and the cleaning brush body 124 are equivalent to a crank slider mechanism, and the rotation of the crank (the first connecting rod 122 and the second connecting rod 123) drives the slider (cleaning brush body 124) to slide.

[0048] The rotation of the first connecting rod 122 and the second connecting rod 123 drives the cleaning brush body 124 to reciprocate in the first direction, so that the cleaning brush body 124 repeatedly scrubs the same position of the ground, thereby improving the cleaning power of the floor scrubber.

[0049] In some embodiments, the driving member 121 includes a motor capable of outputting a rotational motion.

[0050] Optionally, the driving member 121 further includes a gear assembly, the motion input end of the gear assembly is connected to the motor, and the motion output end of the gear assembly is connected to the first connecting rod 122. The gear assembly can be used as a reducer, a transmission mechanism, etc.

[0051] In some embodiments, see Figure 4 , one end of the second connecting rod 123 away from the cleaning brush body 124 is rotatably connected to the cleaning brush body 124. The second connecting rod 123 rotates under the drive of the first connecting rod 122, and the movement of the end of the second connecting rod 123 close to the cleaning brush body 124 can be decomposed into movement in the first direction and movement in the vertical direction. In order to make the cleaning brush body 124 move only in the first direction, the cleaning brush body 124 is rotatably connected to the second connecting rod 123.

[0052] In some embodiments, bristles for contacting the ground are disposed on the lower side of the cleaning brush body 124 , and the side of the cleaning brush body 124 is rotatably connected to the second connecting rod 123 , facilitating the connection layout between the second connecting rod 123 and the cleaning brush body 124 .

[0053] In other embodiments of the present invention, the cleaning brush assembly 12 includes a cylinder capable of outputting reciprocating linear motion and a cleaning brush body 124. The cylinder drives the cleaning brush body 124 to reciprocate in a first direction.

[0054] In some embodiments of the present invention, see Figure 5 and Figure 6The cleaning brush body 124 includes a brush head 1243, a brush holder 1241 and an elastic member 1242. The brush holder 1241 is fixed to the base 11. One end of the second connecting rod 123 away from the first connecting rod 122 is rotatably connected to the brush holder 1241. The two ends of the elastic member 1242 are respectively arranged on the brush holder 1241 and the brush head 1243, and the extension direction of the elastic member 1242 is the vertical direction.

[0055] The brush head 1243 has bristles for contacting the ground. The brush holder 1241 is fixed to the base 11, and an elastic member 1242 is provided between the brush holder 1241 and the brush head 1243. Among them, one end of the second connecting rod 123 away from the first connecting rod 122 is rotatably connected to the brush holder 1241, thereby driving the entire cleaning brush body 124 to move. Since the elastic member 1242 can be extended and retracted in the vertical direction, the pressure between the brush head 1243 and the ground can be adjusted. During the forward movement of the floor scrubber, or during the movement of the cleaning brush body 124 in the first direction, the pressure between the brush head 1243 and the ground can be adjusted by the extension and retraction of the elastic member 1242.

[0056] The brush head 1243 is not fixedly connected to the base 11. The brush head 1243 is elastically connected to the brush holder 1241 fixed to the base 11 through the elastic member 1242. When the water inside the water tank assembly 20 increases or decreases, the height of the connection between the brush holder 1241 and the elastic member 1242 will decrease or increase, and the elastic member 1242 will be compressed or extended accordingly to adjust the pressure between the brush head 1243 and the ground. In particular, when there is more water in the water tank, the setting of the elastic member 1242 can reduce the pressure between the brush head 1243 and the ground. Compared with the solution in which the brush head 1243 is directly fixed to the base 11, the bristles on the brush head 1243 are less likely to wear. Moreover, when the first connecting rod 122 and the second connecting rod 123 rotate, the brush holder 1241 of the cleaning brush body 124 will also be subjected to a force in the vertical direction. The elastic member 1242 can buffer the impact force on the brush head 1243, so that the pressure between the brush head 1243 and the ground is in a relatively stable range, ensuring the cleaning strength. In addition, the brush holder 1241 and the brush head 1243 are two separate components, which makes it easier to disassemble and replace the brush head 1243.

[0057] In some embodiments, the cleaning brush body 124 is in an elongated shape, and the length direction of the cleaning brush body 124 is parallel to the first direction, so that a large area of ​​the floor can be scrubbed while the floor scrubber is moving forward.

[0058] In some embodiments, there are multiple elastic members 1242, and the multiple elastic members 1242 are sequentially spaced along the length of the brush head 1243. In this way, the force is evenly applied at each position of the brush head 1243, and the movement of the brush head 1243 is more stable.

[0059] In some embodiments, the elastic member 1242 is a cylindrical spring, which has a lower cost.

[0060] In some embodiments of the present invention, see Figures 4 to 7 A shaft sleeve 125 is fixed on the base 11, so that the brush holder 1241 can move in the first direction; the brush holder 1241 includes a sliding rod 12411, a rotating connection part 12412 and a frame body 12413 connected to the sliding rod 12411, the sliding rod 12411 is slidably arranged on the shaft sleeve 125 along the first direction, and the two ends of the elastic member 1242 are respectively arranged on the frame body 12413 and the brush head 1243, the rotating connection part 12412 is used to cooperate with the second connecting rod 123 for rotational connection, and the rotating connection part 12412 is connected to the sliding rod 12411 or the frame body 12413.

[0061] The brush holder 1241 includes a sliding rod 12411, a rotating connection portion 12412 and a holder body 12413. The sliding rod 12411 is slidably disposed on the shaft sleeve 125 along a first direction. It can be understood that the sliding rod 12411 is inserted into the shaft sleeve 125. When the second connecting rod 123 drives the brush holder 1241 to move along the first direction, the sliding rod 12411 slides along the first direction under the restriction of the shaft sleeve 125. The holder body 12413 is disposed opposite to the brush head 1243, and the elastic member 1242 is disposed between the clamp body and the brush head 1243.

[0062] By configuring the brush holder 1241 as a sliding rod 12411 , a holder body 12413 and a rotating connection portion 12412 , the brush holder 1241 can not only slide smoothly in the first direction, but also provide an installation space for the elastic member 1242 , and can also be conveniently rotatably connected to the second connecting rod 123 .

[0063] In some embodiments, when the floor scrubber is working normally, the sliding rod 12411 and the frame body 12413 are located at the same height, that is, the connection position of the sleeve 125 and the brush holder 1241 and the position of the frame body 12413 are arranged horizontally, which can reduce the occupation of the vertical space, reduce the height of the floor scrubber, and make the internal layout of the floor scrubber more reasonable.

[0064] In some embodiments, the rotating connection portion 12412 and the frame body 12413 are fixedly connected. It can be understood that the rotating connection portion 12412 is formed by extending the frame body 12413 toward the second connecting rod 123.

[0065] In some embodiments, the frame body 12413 and the sliding rod 12411 are fixedly connected, and the sliding rod 12411 is fixed to a portion of the frame body 12413 close to the rotating connection portion 12412 .

[0066] In some embodiments, there are multiple sleeves 125 , which are spaced apart in sequence along the length direction of the sliding rod 12411 , thereby making the movement of the cleaning brush body 124 in the first direction more stable.

[0067] In some embodiments, the length direction of the sliding rod 12411 is parallel to the length direction of the frame body 12413, so that the frame body 12413 moves along its length direction.

[0068] In some embodiments of the present invention, see Figure 4 and Figure 5 , at least part of the frame body 12413 extends below the water tank assembly 20, and a guide wheel 12414 is provided on the side of the frame body 12413 facing the water tank assembly 20. The frame body 12413 at least partly extends below the water tank assembly 20, and the brush head 1243 also extends below the water tank assembly 20, so that the water flowing out of the water tank assembly 20 can cooperate with the brush head 1243 to scrub the floor. A guide wheel 12414 is provided on the side of the frame body 12413 facing the water tank assembly 20, and the guide wheel 12414 is rotatably provided on the frame body 12413, and the guide wheel 12414 is in contact with the bottom side of the water tank assembly 20.

[0069] By providing a guide wheel 12414 on the side of the frame body 12413 facing the water tank assembly 20, the sliding friction between the frame body 12413 and the water tank assembly 20 can be converted into a rolling friction between the guide wheel 12414 and the water tank assembly 20, making the movement of the cleaning brush body 124 smoother.

[0070] In some embodiments, there are multiple guide wheels 12414 , which are spaced apart in sequence along the length direction of the frame body 12413 .

[0071] In some embodiments, the entire frame body 12413 is located below the water tank assembly 20 , or the frame body 12413 is partially located below the water tank assembly 20 .

[0072] In some embodiments of the present invention, see Figure 3 , Figure 7 and Figure 8 The base 11 extends downward to form a shaft seat 111, the shaft seat 111 has a mounting cavity, and the shaft sleeve 125 is located in the mounting cavity. The inner wall of the mounting cavity has a first circumferential positioning portion 1112, and the shaft sleeve 125 has a second circumferential positioning portion 1251 that cooperates with the first circumferential positioning portion 1112.

[0073] The shaft seat 111 is located at the bottom of the base 11, and the shaft seat 111 is used to install the shaft sleeve 125, so that the shaft sleeve 125 is located in the installation cavity of the shaft seat 111, providing a fixed position for the shaft sleeve 125. When the shaft sleeve 125 is installed inside the shaft seat 111, the outer peripheral wall of the shaft sleeve 125 and the inner wall of the installation cavity contact each other, and the first circumferential positioning portion 1112 and the second circumferential positioning portion 1251 cooperate with each other to form a circumferential positioning of the shaft sleeve 125, thereby preventing the shaft sleeve 125 from rotating circumferentially.

[0074] By arranging the shaft seat 111 on the base 11 to install the shaft sleeve 125, the shaft sleeve 125 can be more stably installed on the base 11. Moreover, the shaft sleeve 125 can be circumferentially fixed to the shaft seat 111 through the cooperation of the first circumferential positioning portion 1112 and the second circumferential positioning portion 1251.

[0075] In some embodiments, the side of the shaft seat 111 close to the ground has an opening, and the shaft sleeve 125 can be installed from the opening to enter the interior of the shaft seat 111. In other words, the shaft sleeve 125 can be installed from the bottom of the shaft seat 111 to enter the interior of the shaft seat 111. First, it is convenient to disassemble the shaft sleeve 125 and the cleaning brush body 124, and second, during the movement of the cleaning brush body 124, the shaft sleeve 125 is supported by the cleaning brush body 124 and is not easy to fall off from the shaft seat 111.

[0076] In some embodiments, the shaft seat 111 includes two spaced-apart seat units 1111, the two seat units 1111 enclose the above-mentioned installation cavity, and the sliding rod 12411 is located between the two seat units 1111. By configuring the shaft seat 111 as two spaced-apart seat units 1111, the sliding rod 12411 can penetrate the shaft seat 111 (pass through the gap between the two seat units 1111).

[0077] In some embodiments, the cleaning brush body 124 is fixed on the shaft seat 111 , and the shaft seat 111 provides a mounting position for the cleaning brush body 124 .

[0078] In some embodiments, the first circumferential positioning portion 1112 is a groove on the inner wall of the installation cavity, and the second circumferential positioning portion 1251 is a protrusion formed by radially extending outward from the outer circumferential wall of the sleeve 125. When the protrusion extends into the groove, the first circumferential positioning portion 1112 and the second circumferential positioning portion 1251 cooperate with each other to form circumferential positioning of the sleeve 125.

[0079] Optionally, the groove opening on the inner wall of the installation cavity is arranged facing the ground, so that after the protrusion of the sleeve 125 is aligned with the groove, it can be installed in the shaft seat 111 by vertical movement relative to the shaft seat 111, thereby facilitating the installation of the sleeve 125.

[0080] In some embodiments of the present invention, see Figure 3 and Fig. 9 The number of cleaning brush assemblies 12 is multiple, and the multiple cleaning brush assemblies 12 are sequentially distributed along the first direction or the second direction. The number and distribution of the cleaning brush assemblies 12 can be adaptively designed according to the bottom space layout of the floor scrubber and the cleaning requirements. In this embodiment, the number of cleaning brush assemblies 12 is at least two.

[0081] By setting the number of cleaning brush assemblies 12 to be multiple, the cleaning brush assemblies 12 can be designed in different areas, and the movement directions of the cleaning brush assemblies 12 can be different, thereby improving the cleaning effect.

[0082] In some embodiments, see Figure 3 The number of the cleaning brush assemblies 12 is two, and they are sequentially distributed along the second direction. The sliding rods 12411 of the two cleaning brush assemblies 12 are sequentially arranged in the vertical direction, so that the horizontal space occupied by the two sliding rods 12411 can be reduced, and the vertical space can be fully utilized.

[0083] Optionally, see Figure 8 The shaft sleeves 125 used to limit the two sliding rods 12411 are stacked in the vertical direction. The two adjacent shaft sleeves 125 in the vertical direction have contact surfaces. The two contact surfaces are flat and fit each other, thereby making the two cleaning brush assemblies 12 more stable in the vertical direction.

[0084] Optionally, the two cleaning brush bodies 124 move in the same direction, or the two cleaning brush bodies 124 move in opposite directions. For example, both cleaning brush bodies 124 move to the left, or one cleaning brush body 124 moves to the right and the other cleaning brush body 124 moves to the left.

[0085] In some embodiments, two cleaning brush assemblies 12 share a driving mechanism 120, which includes a driving member 121 and a gear assembly, wherein the number of the driving member 121 is one, and the gear assembly is driven by the driving member 121. The gear assembly has two motion output ends, which are respectively connected to the two cleaning brush bodies 124.

[0086] In other embodiments, the driving mechanisms 120 of the two cleaning brush assemblies 12 are independent of each other.

[0087] In some embodiments, see Fig. 9 , the number of cleaning brush assemblies 12 is two, and they are sequentially distributed along the first direction. In the two cleaning brush assemblies 12, the movement directions of the two cleaning brush bodies 124 can be the same or opposite. For example, both cleaning brush bodies 124 move to the left, or one cleaning brush body 124 moves to the right and the other cleaning brush body 124 moves to the left.

[0088] In other embodiments, see Fig.10 The number of the cleaning brush assembly 12 is one, and the cleaning brush assembly 12 can reciprocate in the first direction.

[0089] In some embodiments of the present invention, see Figures 11 to 13 The water tank assembly 20 includes a water tank shell 21 and a filter structure 23 arranged inside the water tank shell 21. The water tank shell 21 has a water outlet 213 and a water collection port 212. The water inlet of the filter structure 23 is connected to the water collection port 212, and the water outlet 213 of the filter structure 23 is connected to the water storage chamber of the water tank shell 21.

[0090] The water tank housing 21 has a water storage cavity for containing water, and the filter structure 23 is arranged inside the water storage cavity. The water outlet 213 of the water tank housing 21 is used to flow out clean water, and the clean water cooperates with the cleaning brush body 124 to scrub the floor. The water collection port 212 of the water tank housing 21 is used to collect dirty water. Specifically, in the process of the floor scrubber cleaning the floor, clean water flows out from the water outlet 213 of the water tank housing 21. After the cleaning brush body 124 scrubs the floor, the clean water becomes dirty water. The dirty water enters the filter structure 23 from the water collection port 212 of the water tank housing 21 and the water inlet of the filter structure 23, and enters the water storage cavity of the water tank housing 21 from the water outlet 213 of the filter structure 23.

[0091] By setting a filtering structure 23 inside the water tank shell 21, sewage can be recovered. After filtering, the sewage re-enters the interior of the water tank shell 21 and the water is repeatedly recycled. There is no need to frequently add clean water and dump sewage, thereby reducing the capacity and volume of the water tank assembly 20.

[0092] In some embodiments, see Fig.13 The water tank shell 21 has a sewage channel 25 inside, one end of the sewage channel 25 is connected to the water inlet of the filter structure 23, and the other end of the sewage channel 25 is connected to the water collection port 212 of the water tank shell 21, so that sewage can be quickly collected into the filter structure 23 through the sewage channel 25.

[0093] In some embodiments of the present invention, see Fig.11 The side of the water tank shell 21 facing the ground includes a first area 2111, a second area 2112 and a third area 2113 connected in sequence. The height of the first area 2111 is higher than the height of the third area 2113. The first area 2111 covers part of the base 11. The water collection port 212 is opened in the third area 2113, and a scraper bar 22 is provided at the third area 2113. The scraper bar 22 is arranged at the rear of the cleaning brush body 124. The scraper bar 22 has a water collection tank 221. The water collection port 212 is located inside the water collection tank 221.

[0094] The side of the water tank housing 21 facing the ground is the bottom side of the water tank housing 21. The first area 2111, the second area 2112 and the third area 2113 are connected in sequence, and the third area 2113 is closer to the ground than the first area 2111. The water collection port 212 is arranged in the third area 2113, which is closer to the ground, so that the sewage can be collected more effectively. The water tank housing 21 overlaps with the base 11 at the first area 2111, which can increase the contact area between the water tank assembly 20 and the main assembly 10, and facilitate the connection between the two. The scraper bar 22 is arranged behind the cleaning brush body 124. It can be understood that when the forward direction of the floor scrubber is the front-to-back direction, the scraper bar 22 is located at the rear side of the cleaning brush body 124. In this way, the scraper bar 22 can scrape the sewage forward during the forward process of the floor scrubber, and then collect the sewage into the water collection tank 221, and then the sewage enters the inside of the water collection port 212 along the water collection tank 221.

[0095] By providing the first area 2111, the second area 2112 and the third area 2113 connected in sequence, the contact area between the water tank assembly 20 and the main assembly 10 can be increased, and the connection between the two can be more stable. By providing the scraper bar 22 and providing the water collection tank 221 inside the scraper bar 22, no sewage will remain on the ground after cleaning, and the sewage can quickly enter the water collection tank 221 and quickly enter the filter structure 23 through the water collection port 212.

[0096] In some embodiments, the second region 2112 is an inclined surface or a stepped surface, which can generate a height difference between the first region 2111 and the third region 2113 .

[0097] In some embodiments of the present invention, see Figure 3 and Fig.11 The water tank assembly 20 also includes a water supply bar 13 arranged in front of the cleaning brush body 124, the water supply bar 13 has a water inlet connected to the water outlet 213 of the water tank shell 21, and a plurality of water outlet holes 131 are opened on the side of the water supply bar 13 facing the ground.

[0098] The water supply bar 13 has an inner cavity, and the water inlet of the water supply bar 13 is connected to the water storage cavity of the water tank housing 21, and can be connected through a channel or a hose formed by the housing. Specifically, when the floor scrubber is working, the clean water inside the water tank housing 21 enters the interior of the water supply bar 13, and is sprayed onto the ground from the water outlet 131 of the water supply bar 13, and cooperates with the cleaning brush body 124 to scrub the ground.

[0099] By setting the water supply bar 13, clean water can be sprayed on the ground stably, evenly and over a large area, and the water supply bar 13 is set in front of the cleaning brush body 124. When the floor scrubber moves forward, the water sprayed on the ground will contact the cleaning brush body 124 and cooperate with the cleaning brush body 124 to scrub.

[0100] In some embodiments, the water supply bar 13 is arc-shaped, and the shape of the water supply bar 13 may be similar to the structural shape of the edge of the floor scrubber, so as to more effectively utilize the bottom space of the floor scrubber.

[0101] In some embodiments of the present invention, see Fig.13 The water tank housing 21 includes a water tank seat 214 and a water tank cover 215 covering the opening of the water tank seat 214 , the water tank seat 214 is detachably connected to the base 11 , the filter structure 23 is arranged opposite to the opening, and the filter structure 23 is detachably connected to the water tank seat 214 .

[0102] The water tank seat 214 has an opening, and the water tank cover 215 is disposed at the opening of the water tank seat 214, so that a closed water storage cavity is formed inside the water tank housing 21. By making the filter structure 23 face the opening of the water tank seat 214, the filter structure 23 can be disassembled and assembled from the opening, which is convenient for disassembly and installation of the filter structure 23, that is, convenient for replacement of the filter structure 23.

[0103] In some embodiments, the filter structure 23 is fixed to the water tank seat 214 by snaps, and no other disassembly tools are required to disassemble and assemble the filter structure 23.

[0104] In some embodiments, the water tank cover 215 is fixed to the water tank seat 214 by buckles, and no other disassembly tools are required to disassemble and assemble the water tank cover 215.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
