Description

TECHNICAL FIELD

[0001] The present application relates to the field of cleaning equipment, in particular to a water tank and a sweeping robot. BACKGROUND

[0002] With the progress of the times, users have more and more functional requirements for sweeping robots, such as adding a mop structure to a traditional sweeping robot to realize the function of sweeping and washing the floor. In order to improve the effect of sweeping and washing, a driving mechanism is arranged to drive the movement of the mop structure, so as to realize the active movement of the mop mechanism relative to the ground and improve the effect of sweeping and washing. However, the stability of the movement of the existing mop mechanism is low, resulting in poor effect of sweeping and washing. SUMMARY

[0003] The purpose of the present application is to provide a water tank and a sweeping robot, which aims to solve the problem of poor sweeping and washing effect of the sweeping robot in the prior art.

[0004] To achieve this purpose, the embodiments of the present application adopt the following technical solutions:

[0005] The water tank comprises a shell, at least one sliding guide block detachably connected to the bottom of the shell, a mop support assembly movably installed between the shell and the sliding guide block, and a driving assembly for driving the movement of the mop support assembly; the sliding guide hole is provided on the sliding guide block for installing the sliding guide hole, and the inner wall of the sliding guide hole is provided with a limiting table, the sliding guide block comprises a limiting portion abutting against the side of the limiting table away from the shell, and a connecting portion connected with the limiting portion; one end of the connecting portion away from the limiting portion penetrates the sliding guide hole and is connected with the shell. Since the limiting portion abuts against the limiting table and is located in the sliding limiting hole, the limiting portion, that is, the sliding guide block, can limit the movement of the mop support assembly within a certain range by contacting the inner wall of the sliding guide hole. Therefore, when the mop support assembly installed on the sliding guide block is driven to move by the driving assembly, it can only move within a certain range along the preset path. Therefore, the cooperation of the sliding guide block and the sliding guide hole makes the mop support assembly move only according to the preset path, and completes the stable and regular sweeping and washing action on the ground, which can ensure the good sweeping and washing cleaning effect of the sweeping robot with the water tank.

[0006] In one embodiment, the bottom of the shell is provided with a fixed column corresponding to the sliding guide block, and the sliding guide block is detachably connected with the fixed column through the connecting portion. That is, the sliding guide block is connected with the shell through the fixed column, which can avoid directly connecting the sliding guide block with the shell through a hole in the shell, thereby ensuring the strength of the shell. Moreover, the fixed column has a certain height, and the connection of the sliding guide block and the fixed column is more convenient, and the disassembly and assembly of the mop support assembly are also more convenient.

[0007] In one embodiment, the number of sliding guide blocks is three or more, and the number of fixed columns is three or more and corresponds to the sliding guide blocks one by one. Three or more sliding guide blocks are provided, and are connected to the shell through the fixed columns respectively, so that at least three connection points between the shell and the mop support assembly are achieved. Taking three connection points as an example, the three points form a triangle and determine a fixed plane, so as to limit the movement of the mop support assembly in the plane, ensure the stability of the movement of the mop support assembly, and further ensure the cleaning effect of the mop.

[0008] In one embodiment, each of the fixed columns is integrally formed with the shell, so as to ensure the consistency of the height of the three or more fixed columns protruding from the surface of the bottom shell. The plane determined by the three connection points or three or more connection points tends to be horizontal, so that the mop support assembly tends to be located on a horizontal plane, and can be in close contact with the ground during cleaning, so that there are no gaps, the cleaning force is good, and the consistency of the effect in each place is strong.

[0009] In one embodiment, the fixed column is provided with a fixed hole, the sliding guide block is provided with a connecting through hole, a connecting screw is arranged between the fixed column and the sliding guide block, and the connecting screw penetrates through the connecting through hole and is screwed with the fixed hole. During installation of the mop support assembly, the sliding guide hole on the mop support assembly is first aligned with the fixed column, the mop support is placed on the shell, the sliding guide block is inserted into the sliding guide hole from the side of the mop support assembly away from the shell, and finally the connecting screw is tightened to connect the sliding guide block and the fixed column, and at the same time, the mop support assembly is installed between the shell and the sliding guide block. Therefore, the installation of the mop support assembly is simple and convenient.

[0010] In one embodiment, the connecting portion is provided with a positioning groove, the fixed column is inserted into the positioning groove, and the connecting through hole is arranged at the bottom of the positioning groove.

[0011] In one embodiment, the housing is provided with a contact protrusion assembly at each of the fixing columns, the contact protrusion assembly comprising two abutting protrusions arranged opposite and spaced apart, the fixing column and the two abutting protrusions each having a gap therebetween, the thickness of the fixing column being greater than the thickness of the abutting protrusions, and the connecting portion being located between the two abutting protrusions. The mop support assembly is in contact with the two abutting protrusions to achieve line contact instead of surface contact with the surface of the housing. The line contact formed by two points not only achieves stable contact, but also does not have a large friction force due to the large contact area. Therefore, when the driving assembly drives the mop support assembly to move to complete the operation of mopping and washing the floor, the mop support assembly can move more smoothly and complete the reciprocating motion quickly, and the effect of mopping and washing is not easily affected by the large friction force. The fixing column and the two abutting protrusions each have a gap therebetween, and the connecting portion is located between the two abutting protrusions, i.e. the abutting protrusions also limit the connecting portion, further improving the stability of the connection between the sliding guide block and the fixing column, and the sliding guide block is not easily loosened under the impact of the reciprocating motion of the mop support assembly.

[0012] In one embodiment, the sliding guide hole is a waist-shaped hole, the limiting portion is disc-shaped, and the length direction of the waist-shaped hole is perpendicular to the length direction of the housing. When the sliding guide block is used as a guide and limiting part, the movement of the mop support assembly is reciprocating motion in the length direction of the waist-shaped hole to complete the mopping and washing operation, and the forward and backward movement of the sweeper, the mop support assembly can complete the mopping and washing operation in the front and back directions and the left and right directions, further improving the mopping and washing ability of the sweeper when the water tank is applied to the sweeper. At the same time, the limiting portion is disc-shaped, which can realize the tangency of the limiting portion and the inner wall of the sliding guide hole, and further realize line contact, reduce the contact area, reduce the friction loss, improve the frequency of the movement of the mop support assembly, and ensure the mopping and washing ability.

[0013] In one embodiment, the driving assembly comprises a driving motor arranged in the housing, a driving connecting piece connected with an output shaft of the driving motor, and a circular driving piece rotatably arranged on the driving connecting piece; a gap is formed between an axis of the circular driving piece and an axis of the output shaft of the driving motor; a transmission groove is arranged on the mop support assembly, the circular driving piece is located in the transmission groove, the transmission groove is a waist-shaped groove, and a length direction of the transmission groove is the same as a length direction of the housing. The circular driving piece is eccentrically arranged on the driving motor and located in the transmission groove, and can synchronously rotate with the driving motor to drive the driving connecting piece to rotate; and in the transmission groove, the circular driving piece can move along the length direction of the transmission groove as one of the partial movements. Since the width direction (the direction with a smaller distance between the opposite inner walls) of the transmission groove is relatively narrow, the circular driving piece exerts force on the inner walls at both ends of the transmission groove in sequence when the circular driving piece moves in a circular manner, and drives the mop support assembly to move in the width direction of the transmission groove, that is, to move left and right (left-right movement) in the width direction of the housing and the sweeper. In combination with the forward and backward movement of the sweeper, the front and rear and left and right wiping and washing operations can be completed, and the wiping and washing cleaning capacity of the sweeper when the water tank is applied to the sweeper is further improved. In the embodiments of the present application, the eccentric circular driving piece is matched with the waist-shaped transmission groove, and the sliding guide hole on the mop support assembly is matched with the sliding guide block, so that the mop support assembly can be accurately and stably driven to move left and right. Since at least two left-right guide and limiting actions are provided, high-precision left-right movement can be achieved, and deviation in other directions is less likely to occur, so that the sweeper with the water tank can stably move left and right, and better wiping and washing cleaning effect is achieved.

[0014] In one embodiment, the housing is provided with a transmission ring, the transmission ring and the surface of the housing form the transmission groove, the outer periphery of the transmission ring is provided with a reinforcing rib, and the circular driving piece is a bearing. The outer periphery of the transmission ring is provided with a reinforcing rib, which improves the strength of the transmission ring and prevents deformation under external force, ensures the accuracy of transmission, and further ensures the accuracy of driving the mop support assembly to move. Optionally, the circular driving piece is a bearing, which has good rotation performance and can smoothly rotate in the transmission groove, thereby reducing the friction between the inner wall of the transmission groove and the circular driving piece and smoothly driving the mop support assembly to move left and right.

[0015] In one embodiment, the shell has a first water storage cavity and a second water storage cavity, and a communication passage is arranged between the first water storage cavity and the second water storage cavity; the shell comprises a bottom shell assembly and a shower cover sealingly connected to the bottom shell assembly; a gap between the shower cover and the bottom shell assembly forms the communication passage; the bottom shell assembly is provided with a sealing groove, the shower cover is provided with a sealing protrusion, the sealing protrusion is inserted into the sealing groove, and a sealing glue is arranged between the inner surface of the sealing groove and the sealing protrusion. Optionally, the above-mentioned fixing column can be arranged at a position coinciding with the shower cover, and a corresponding through hole is arranged on the shower cover to allow the fixing column to pass through and be connected to the sliding guide block. At the same time, a sealing groove surrounding the fixing column is arranged around the fixing column to achieve the sealing connection between the shower cover and the shell at this position. The shower cover is provided with a water outlet, and the mop support assembly is provided with a corresponding water outlet hole, which is a waist-shaped hole, facilitating smooth water outlet when the mop support assembly slides.

[0016] The sweeping machine comprises the water tank described in any one of the above embodiments.

[0017] The beneficial effects of the embodiments of the present application are as follows: since the limiting portion in the water tank of the sweeping machine abuts against the limiting table and is located in the sliding limiting hole, the limiting portion, i.e., the sliding guide block, can limit the movement of the mop support assembly within a certain range by contacting the inner wall of the sliding guide hole, so that when the mop support assembly mounted on the sliding guide block is driven to move by the driving assembly, it can only move along the preset path within a certain range. Therefore, the cooperation of the sliding guide block and the sliding guide hole makes the mop support assembly move only according to the preset path to complete stable and regular mopping and washing actions on the ground, which can ensure better mopping and washing cleaning effect of the sweeping machine with the water tank.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0032] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an indicated number of technical features. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0033] The implementation of the present application is described in detail below in conjunction with specific embodiments.

[0034] As shown in Figures 1-3 The water tank according to the embodiments of the present application is installed on a sweeper and used to drip water to the ground for cleaning. The water tank comprises a shell 1, at least one sliding guide block 2 detachably connected to the bottom of the shell 1, a mop support assembly 3 movably installed between the shell 1 and the sliding guide block 2, and a driving assembly 4 for driving the mop support assembly 3 to move. The driving assembly 4 is used to drive the mop support assembly 3 to move as a whole between the shell 1 and the sliding guide block 2, thereby completing the work of mopping the ground.

[0035] The mop support has a sliding guide hole 301 for mounting the sliding guide block 2, and the inner wall of the sliding guide hole 301 is provided with a limiting table 3011 which is protruded from the inner wall of the sliding guide hole 301 to the center of the hole, so as to avoid the sliding guide block 2 from being separated from the mop support assembly 3. The sliding guide block 2 comprises a limiting portion 201 which abuts against the side of the limiting table 3011 away from the shell 1, and a connecting portion 202 connected to the limiting portion 201; the end of the connecting portion 202 away from the limiting portion 201 penetrates through the sliding guide hole 301 and is connected to the shell 1. Therefore, after the sliding guide block 2 penetrates through the sliding guide hole 301 and is connected to the bottom of the shell 1, the limiting portion 201 is used to limit the mop support, so that the mop support is movably installed on the shell 1 and will not be separated from the shell 1.

[0036] In the embodiments of the present application, since the limiting portion 201 abuts against the limiting table 3011 and is located in the sliding limiting hole, the limiting portion 201, i.e. the sliding guide block 2, can limit the mop support assembly 3 to move within a certain range by contacting the inner wall of the sliding guide hole 301. Therefore, when the mop support assembly 3 mounted on the sliding guide block 2 is driven to move by the driving assembly 4, it can only move within a certain range along the preset path. Therefore, the cooperation of the sliding guide block 2 and the sliding guide hole 301 makes the mop support assembly 3 move only according to the preset path, so as to complete the stable and regular mopping action on the ground, which can ensure the better mopping and cleaning effect of the sweeper with the water tank.

[0037] Please refer to Figure 2 and Figure 6As another specific embodiment of the water tank provided in the present application, the bottom of the shell 1 is provided with fixed columns 101 corresponding to the sliding guide blocks 2, and the sliding guide blocks 2 are detachably connected with the fixed columns 101 through the connecting portions 202. That is, the sliding guide blocks 2 are connected with the shell 1 through the fixed columns 101, which can avoid directly opening holes in the shell 1 to connect with the sliding guide blocks 2, thereby ensuring the strength of the shell 1. In addition, the fixed columns 101 have a certain height, and when the sliding guide blocks 2 are connected with the fixed columns 101, the operation is more convenient, and the disassembly and assembly of the mop support assembly 3 are relatively convenient.

[0038] Please refer to Figures 1-2 As another specific embodiment of the water tank provided in the present application, the number of the sliding guide blocks 2 is three or more, and the number of the fixed columns 101 is three or more and is arranged one by one corresponding to the sliding guide blocks 2. By arranging three or more sliding guide blocks 2 and connecting them with the shell 1 through the fixed columns 101 respectively, at least three connection points between the sliding guide blocks 2 and the shell 1 are realized. Taking three connection points as an example, the three points form a triangle, and a fixed plane is determined, thereby limiting the movement of the mop support assembly 3 in the plane, ensuring the stability of the movement of the mop support assembly 3, and further ensuring the cleaning and washing effect.

[0039] Optionally, when the number of the sliding guide blocks 2 is three, the three fixed columns 101 can form an isosceles triangle, so as to further form a stable plane.

[0040] Please refer to Figures 1-3 As another specific embodiment of the water tank provided in the present application, each fixed column 101 is integrally formed with the shell 1, thereby ensuring the consistency of the height of the three or more fixed columns 101 protruding from the surface of the bottom shell. The plane determined by the three connection points or three or more connection points tends to be horizontal, thereby making the mop support assembly 3 tend to be located on a horizontal plane, and the mop support assembly 3 can be in close contact with the ground everywhere during cleaning, so that there is no gap, and the cleaning force is good and the consistency of the effect everywhere is strong.

[0041] Please refer to Figure 6As another specific embodiment of the water tank provided by the present application, a fixing column 101 is provided with a fixing hole 1011, a sliding guide block 2 is provided with a connecting through hole 203, and a connecting screw 5 is arranged between the fixing column 101 and the sliding guide block 2, penetrates through the connecting through hole 203 and is screwed with the fixing hole 1011 (the fixing column is generally a plastic part, the fixing hole 1011 can be a light hole with an inner diameter slightly smaller than the outer diameter of the connecting screw 5, and the connecting screw 5 can be a self-tapping screw screwed with the inner wall of the fixing hole 1011; of course, in other embodiments, if the fixing column 101 is made of other materials or is harder, the fixing hole 1011 can also be a threaded hole to facilitate threaded connection with the connecting screw 5). When installing the mop holder assembly 3, the sliding guide hole 301 on the mop holder assembly 3 can be aligned with the fixing column 101, the mop holder is placed on the shell 1, the sliding guide block 2 is inserted into the sliding guide hole 301 from the side of the mop holder assembly 3 away from the shell 1, and finally the connecting screw 5 is tightened to connect the sliding guide block 2 with the fixing column 101, and at the same time the mop holder assembly 3 is installed between the shell 1 and the sliding guide block 2, so that the installation of the mop holder assembly 3 is relatively simple and convenient.

[0042] Similarly, when the mop holder assembly 3 needs to be replaced or cleaned, the connecting screw 5 only needs to be loosened to release the connection between the sliding guide block 2 and the fixing column 101, so that the mop holder assembly 3 can be removed from the shell 1 at the same time, realizing the convenient disassembly operation of the mop holder assembly 3.

[0043] Of course, in other embodiments, the detachable connection between the sliding guide block 2 and the fixing column 101 can also be achieved by using a clamping connection or other connection methods to install the mop holder assembly 3 between the shell 1 and the sliding guide block 2.

[0044] Please refer to Figure 6 As another specific embodiment of the water tank provided by the present application, the connecting portion 202 is provided with a positioning groove 2021, and the fixing column 101 is inserted into the positioning groove 2021, which improves the stability of the connection between the sliding guide block 2 and the fixing column 101 and ensures the connection strength, so that the connection is not easy to loosen under the impact of the mop holder assembly 3. The connecting through hole 203 is arranged at the bottom of the positioning groove 2021, and the connecting screw 5 can be connected with the fixing column 101 after penetrating through the connecting through hole 203, realizing the compactness of the structure at the connection between the sliding guide block 2 and the fixing column 101.

[0045] Please refer to Figure 2 and Figure 6As another specific embodiment of the water tank provided in the present application, the housing 1 is provided with a contact protrusion assembly 102 at each fixing column 101, the contact protrusion assembly 102 comprises two abutting protrusions 1021 arranged oppositely and spaced apart, and the thickness of the fixing column 101 is greater than the thickness of the abutting protrusion 1021. Therefore, when the mop support assembly 3 is installed between the housing 1 and the sliding guide block 2, the mop support assembly 3 is in contact with the two abutting protrusions 1021, realizing line contact instead of surface contact with the surface of the housing 1 as a whole. The line contact formed by two points not only realizes stable contact, but also does not have a large friction force due to a large contact area. Therefore, when the driving assembly 4 drives the mop support assembly 3 to move to complete the operation of mopping and washing the floor, the mop support assembly 3 can move more smoothly and complete the reciprocating motion quickly, and the effect of mopping and washing is not easily affected by a large friction force.

[0046] The fixing column 101 and the two abutting protrusions 1021 have gaps therebetween, and the connecting portion 202 is located between the two abutting protrusions 1021, that is, the abutting protrusions 1021 and the fixing column 101 also limit the connecting portion 202, further improving the stability of the connection between the sliding guide block 2 and the fixing column 101, and the sliding guide block 2 is not easy to loosen under the impact of the reciprocating motion of the mop support assembly 3.

[0047] Please refer to Figures 1-3 As another specific embodiment of the water tank provided in the present application, the sliding guide hole 301 is a waist-shaped hole, and the limiting portion 201 is disc-shaped. The length direction of the waist-shaped hole (the direction with a larger distance between the opposite inner walls, that is, the direction in which the sliding guide block 2 can move) is perpendicular to the length direction of the housing 1 (the front-to-back direction of the housing 1, that is, the direction in which the sweeping machine moves forward and backward).

[0048] Therefore, the movement of the mop support assembly 3 guided by the sliding guide block 2 as the limiting portion 201 is reciprocating motion in the length direction of the waist-shaped hole, which completes the mopping and washing operation, and cooperates with the forward and backward movement of the sweeping machine to complete the mopping and washing operation in the front-to-back direction and the left-to-right direction, further improving the mopping and washing ability of the sweeping machine when the water tank is applied to the sweeping machine.

[0049] Meanwhile, the limiting portion 201 is disc-shaped, which can realize tangency between the limiting portion 201 and the inner wall of the sliding guide hole 301, further realizing line contact, reducing the contact area, reducing the friction loss, improving the frequency of the movement of the mop support assembly 3, and ensuring the mopping and washing ability.

[0050] Please refer to Figures 3-4 and Figures 7-8As another specific embodiment of the water tank provided in the present application, the driving assembly 4 comprises a driving motor 401 arranged in the shell 1, a driving connecting piece 402 connected with the output shaft of the driving motor 401, and a circular driving piece 403 rotatably arranged on the driving connecting piece 402; the driving motor 401 drives the driving connecting piece 402 to rotate, and further drives the circular driving piece 403 on the driving connecting piece 402 to rotate.

[0051] The axis of the circular driving piece 403 and the axis of the output shaft of the driving motor 401 form a gap, that is, the circular driving piece 403 is arranged eccentrically; the mop support assembly 3 is provided with a transmission groove 302, and the circular driving piece 403 is located in the transmission groove 302. The transmission groove 302 is a waist-shaped groove, and the length direction (the direction with a larger distance between the opposite inner walls, that is, the direction in which the circular driving piece 403 can move) of the transmission groove 302 is the same as the length direction (the front-rear direction of the shell 1, that is, the direction in which the sweeper machine moves forward or backward) of the shell 1. Therefore, the circular driving piece 403 connected with the driving motor 401 and located in the transmission groove 302 can rotate synchronously with the driving motor 401 driving the driving connecting piece 402 to rotate; and in the transmission groove 302, it can move along the length direction of the transmission groove 302 as one of the partial movements. Since the width direction (the direction with a smaller distance between the opposite inner walls) of the transmission groove 302 is relatively narrow, the circular driving piece 403 will sequentially apply force to the inner walls at both ends of the width direction of the transmission groove 302 when it moves in a circular manner, and drive the mop support assembly 3 to move in the width direction of the transmission groove 302, that is, drive the mop support assembly 3 to move in the width direction (left-right movement) of the shell 1 and the sweeper machine. In combination with the forward and backward movement of the sweeper machine, the front and rear and left and right movements can be completed, and the cleaning ability of the sweeper machine when the water tank is applied to the sweeper machine is further improved.

[0052] In the embodiments of the present application, the eccentrically arranged circular driving piece 403 cooperates with the waist-shaped transmission groove 302, and the sliding guide hole 301 on the mop support assembly 3 cooperates with the sliding guide block 2, to accurately and stably drive the mop support assembly 3 to move left and right. Since at least two left-right guide and limiting actions are provided, high-precision left-right movement can be achieved, and deviation in other directions is less likely to occur, so that the sweeper machine with the water tank can stably move left and right, and further achieve good mopping and cleaning effect.

[0053] Please refer to Figure 7As another specific embodiment of the water tank provided in the present application, the shell 1 is provided with a transmission ring 303, and the transmission ring 303 and the surface of the shell 1 enclose a transmission groove 302, instead of being provided with a groove on the shell 1, so as to ensure the strength of the shell 1. The outer circumferential surface of the transmission ring 303 is provided with a reinforcing rib 304, so as to improve the strength of the transmission ring 303, and the transmission ring 303 is not easy to be deformed after being subjected to external force, so as to ensure the transmission precision, and further ensure the precision of driving the mop support assembly 3 to move.

[0054] Optionally, the circular driving member 403 is a bearing, has good rotation performance, can rotate smoothly in the transmission groove 302, and further reduces the friction between the circular driving member 403 and the inner wall of the transmission groove 302, so as to smoothly drive the mop support assembly 3 to move left and right.

[0055] Please refer to Figures 3-6 As another specific embodiment of the water tank provided in the present application, the shell 1 has a first water storage cavity 103 and a second water storage cavity 104, and a communication passage 107 is arranged between the first water storage cavity 103 and the second water storage cavity 104. The shell 1 comprises a bottom shell assembly 105 and a shower cover 106 which is in sealed connection with the bottom shell assembly 105. The gap between the shower cover 106 and the bottom shell assembly 105 forms the communication passage 107. The bottom shell assembly 105 is provided with a sealing groove 1051, and the shower cover 106 is provided with a sealing protrusion 1061 which is inserted into the sealing groove 1051, and a sealing glue is arranged between the inner surface of the sealing groove 1051 and the sealing protrusion 1061.

[0056] The embodiment of the present application also provides a sweeping machine comprising the water tank in any one of the above embodiments. The sweeping machine with the water tank in the above embodiment is provided with a sliding guide hole 301 for mounting the sliding guide block 2 on the mop support, and the inner wall of the sliding guide hole 301 is provided with a limiting table 3011 which is protruded from the inner wall of the sliding guide hole 301 to the hole center, so as to avoid the sliding guide block 2 from being separated from the mop support assembly 3. The sliding guide block 2 comprises a limiting portion 201 which is in abutment with the side of the limiting table 3011 away from the shell 1, and a connecting portion 202 which is connected with the limiting portion 201. The end of the connecting portion 202 away from the limiting portion 201 penetrates through the sliding guide hole 301 and is connected with the shell 1. Therefore, after the sliding guide block 2 penetrates through the sliding guide hole 301 and is connected with the bottom of the shell 1, the limiting portion 201 is used to limit the mop support, so that the mop support is movably mounted on the shell 1 and will not be separated from the shell 1.

[0057] Since the limiting portion 201 abuts against the limiting table 3011 and is located in the sliding limiting hole, the limiting portion 201, that is, the sliding guide block 2, can limit the mop support assembly 3 to move within a certain range through the contact with the inner wall of the sliding guide hole 301. Therefore, when the mop support assembly 3 installed on the sliding guide block 2 is driven to move by the driving assembly 4, the mop support assembly 3 can only move along the preset path within a certain range. Therefore, the cooperation of the sliding guide block 2 and the sliding guide hole 301 makes the mop support assembly 3 move along the preset path, completes the stable and regular mopping action on the ground, and can ensure a better mopping and cleaning effect.

[0058] Please refer to Figure 2 and Figure 6 In one embodiment, the housing 1 is provided with a contact protrusion assembly 102 at each fixed column 101, the contact protrusion assembly 102 includes two abutting protrusions 1021 arranged oppositely and spaced apart, and the thickness of the fixed column 101 is greater than the thickness of the abutting protrusion 1021. Therefore, when the mop support assembly 3 is installed between the housing 1 and the sliding guide block 2, the mop support assembly 3 contacts the two abutting protrusions 1021 to achieve line contact instead of surface contact with the surface of the housing 1. The line contact formed by two points not only achieves stable contact, but also does not have a large friction force due to the large contact area. Therefore, when the driving assembly 4 drives the mop support assembly 3 to move to complete the mopping operation on the ground, the mop support assembly 3 can move more smoothly and complete the reciprocating motion quickly, and it is not easy to affect the mopping and cleaning effect due to the large friction force.

[0059] The fixed column 101 and the two abutting protrusions 1021 have gaps therebetween, and the connecting portion 202 is located between the two abutting protrusions 1021, that is, the abutting protrusions 1021 and the fixed column 101 also limit the connecting portion 202, further improving the stability of the connection between the sliding guide block 2 and the fixed column 101, and the sliding guide block 2 is not easy to loosen under the impact of the reciprocating motion of the mop support assembly 3.

[0060] Please refer to Figures 3-4 and Figures 7-8 In one embodiment, the driving assembly 4 includes a driving motor 401 arranged in the housing 1, a driving connecting piece 402 connected with the output shaft of the driving motor 401, and a circular driving piece 403 rotatably installed on the driving connecting piece 402; the driving motor 401 drives the driving connecting piece 402 to rotate, and in turn drives the circular driving piece 403 on the driving connecting piece 402 to rotate.

[0061] The axis of the circular driving member 403 is spaced apart from the axis of the output shaft of the driving motor 401, that is, the circular driving member 403 is eccentrically arranged; the mop support assembly 3 is provided with a transmission groove 302, and the circular driving member 403 is located in the transmission groove 302. The transmission groove 302 is a waist-shaped groove, and the length direction (the direction with a relatively large distance between the opposite inner walls, that is, the direction in which the circular driving member 403 moves) of the transmission groove 302 is the same as the length direction (the front-rear direction of the shell 1, that is, the direction in which the sweeper machine moves forward or backward) of the shell 1. Therefore, the circular driving member 403, which is connected to the driving motor 401 and located in the transmission groove 302, can rotate synchronously with the driving motor 401; and in the transmission groove 302, the circular driving member 403 can move along the length direction of the transmission groove 302 as one of the partial movements. Since the width direction (the direction with a relatively small distance between the opposite inner walls) of the transmission groove 302 is relatively narrow, the circular driving member 403 will sequentially apply force to the inner walls at both ends of the width direction of the transmission groove 302 when moving in a circular manner, and drive the mop support assembly 3 to move in the width direction of the transmission groove 302, that is, drive the mop support assembly 3 to move in the width direction (left-right movement) of the shell 1 and the sweeper machine. In combination with the forward and backward movement of the sweeper machine, the front and rear and left and right wiping operations can be completed, and the wiping and cleaning ability of the sweeper machine with the water tank is further improved.

[0062] In the embodiments of the present application, the eccentrically arranged circular driving member 403 cooperates with the waist-shaped transmission groove 302, and the sliding guide hole 301 on the mop support assembly 3 cooperates with the sliding guide block 2, to accurately and stably drive the mop support assembly 3 to move left and right. Since at least two left-right guide and limiting actions are provided, the left-right movement can be achieved with high precision, and deviation in other directions is less likely to occur, so that the sweeper machine with the water tank can move left and right stably, and better wiping and cleaning effect can be achieved.

[0063] Meanwhile, the sweeper machine provided in the embodiments of the present application also has other technical effects of the water tank in the above embodiments, which will not be described here.

[0064] It can be understood that the scheme in another specific embodiment can be an implementable embodiment further improved on the basis of other embodiments.

[0065] Obviously, the above embodiments of the present application are only examples for clear illustration of the present application, and are not intended to limit the embodiments of the present application. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
