[0045] In some embodiments, the bottom shell has at least one water replenishment channel; the cleaning unit also includes a supporting structure, the cleaning element is fixed on the supporting structure, a water outlet channel connected to the water replenishment channel is provided at a position of the supporting structure corresponding to the water replenishment channel, and a first water outlet connected to the water outlet channel is provided on a side of the supporting structure facing the cleaning element to replenish water to the cleaning element through the first water outlet.

[0046] By arranging a water replenishing channel on the bottom shell, water is replenished to the cleaning element, so that the cleaning element is kept moist and the cleaning effect is improved.

[0050] In this way, the cleaning equipment can replenish water to the cleaning parts through the clean water tank carried by itself through the water replenishment pipeline and the water replenishment channel, without providing water to the water replenishment channel from other places, thereby improving the convenience of water replenishment.

[0051] In some embodiments, the clean water tank is disposed on the bottom shell and on a side of the first connecting passage away from the second connecting passage.

[0052] In this way, the compactness of the layout of each structure in the fuselage is improved.

[0053] In some embodiments, the clean water tank and the first connecting passage are disposed adjacent to each other, and the clean water tank is disposed at an edge position close to the fuselage.

[0059] In some embodiments, a first groove is provided on the circumference of one end of the water outlet channel facing the bottom shell, and the projection of the first groove in the first direction covers the projection of the water replenishment channel.

[0060] In this way, when water from the water replenishment channel drips into the water outlet channel, the water dripping from the water replenishment channel only needs to be within the range of the first groove, thereby reducing the alignment accuracy between the water replenishment channel and the water outlet channel and reducing equipment costs.

[0061] In some embodiments, a second groove is provided in the circumference of one end of the second overflow channel facing the bottom shell, and the projection of the second groove in the first direction covers the projection of the first overflow channel.

[0062] In this way, when water from the first overflow channel drips into the second overflow channel, it is sufficient as long as the water dripping from the first overflow channel is within the range of the second groove, thereby reducing the alignment accuracy between the first overflow channel and the second overflow channel and reducing equipment costs.

[0066] In this way, the power of the driving motor is transmitted to the power transmission member through the driving member to drive the power transmission member to swing back and forth around the first rotation axis, so as to realize the twisting movement of the power transmission member around the first rotation axis in the horizontal plane, thereby increasing the vibration area of ​​the cleaning member and improving the mopping and cleaning effect of the cleaning member.

[0067] In some embodiments, the driving member includes a driving body extending along the axial direction of the output shaft, and the driving portion is connected to one end of the driving body.

[0068] In this way, the driving motor can drive the driving part to rotate eccentrically via the driving body, and the structure is simple and easy to implement.

[0069] In some embodiments, the driving body has an axial hole, and the output shaft passes through the axial hole to connect with the driving member.

[0070] In this way, by setting the driving body as a shaft hole structure matching the output shaft, the output shaft is inserted into the shaft hole to achieve the connection between the output shaft and the driving member, which has a simple structure, is easy to implement and has low cost.

[0071] In some embodiments, the driving portion is a convex column, one end of which is connected to the driving body, and the other end of which extends in a direction away from the driving body.

In the related art, the cleaning equipment includes a body, a driving component and a cleaning component, the cleaning component includes a cleaning member, the driving component is arranged in the body, and the driving component is used to drive the cleaning component to lift and vibrate so that the cleaning member performs cleaning operations. However, when the driving component drives the cleaning component to lift, the position of the cleaning component and the driving component in the lifting direction will change. In this way, when the driving component drives the cleaning component to vibrate, there will be a problem that the position between the cleaning component and the driving component changes, resulting in the inability to drive the cleaning component to vibrate, thereby causing a technical problem of poor reliability in driving the cleaning component to vibrate.

[0122] In order to solve the above problems, an embodiment of the present application provides a cleaning device, including a body, a cleaning component and a lifting component, the body including a bottom shell, the cleaning component is arranged on the lower side of the bottom shell, the cleaning component includes a driving unit and a cleaning unit, the cleaning unit includes a cleaning piece, the driving unit is used to drive the cleaning piece to move to perform a cleaning operation, and the lifting component is arranged on the upper side of the bottom shell, and the cleaning unit and the driving unit are driven by the lifting component to move synchronously along a first direction. In this way, when the lifting component drives the cleaning component to move along the first direction, the position between the cleaning unit and the driving unit will not move relative to each other, thereby improving the position reliability between the driving unit and the cleaning unit in the first direction, and further improving the reliability of the driving unit driving the cleaning piece to move to perform a cleaning operation.

[0123] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0124] The present application provides a cleaning device, which may be a wet and dry dual-purpose cleaning robot. For example, the cleaning device may be a mopping robot or a sweeping and mopping robot. The following description will be made by taking the sweeping and mopping robot as an example.

[0125] Please refer to Figure 1 and Figure 2 The cleaning device 10 provided in the embodiment of the present application includes a body 100 and a cleaning component 200 disposed on the body 100. The cleaning component 200 may be a wet cleaning component 200 for wet cleaning such as wet mopping of a surface to be cleaned. The surface to be cleaned may be, for example, the ground, a tabletop, or other surfaces to be cleaned. In the embodiment of the present application, the surface to be cleaned is described as the ground.

[0126] In addition, the cleaning device 10 may further include a roller brush assembly 150, which is used to clean the surface to be cleaned; for example, the roller brush assembly 150 is used to clean the surface to be cleaned along the forward direction of the fuselage 100 (such as along the Figure 1 ), the roller brush assembly 150 is located in front of the cleaning assembly 200; the roller brush assembly 150 cleans the surface to be cleaned; the cleaning assembly 200 wet-mops the surface to be cleaned to form a cleaning mode of sweeping first and then mopping.

[0127] In some embodiments, the roller brush assembly 150 includes a roller brush and a negative pressure generating device. A dust box for collecting garbage is provided in the body 100. For example, a dust suction port 120 connected to the dust box is provided at the bottom of the body 100. The negative pressure generating device includes but is not limited to a negative pressure fan to provide negative pressure suction to the dust suction port 120 through the negative pressure generating device. In this way, when the roller brush rolls relative to the ground, it can gather garbage on the ground to the vicinity of the dust suction port 120. The negative pressure suction force sucks the garbage and dust particles near the dust suction port 120 into the dust box to achieve the purpose of cleaning.

[0128] In some embodiments, the cleaning device 10 may further include a side brush 160, which is disposed in front of the roller brush assembly 150 along the forward direction of the body 100; when the side brush 160 moves relative to the cleaning surface (for example, the side brush 160 rotates), it gathers garbage on the ground to the inside of the cleaning device 10. In this way, the roller brush assembly 150 can collect the garbage gathered to the inside of the cleaning device 10 into the dust box in the body 100 by rolling and sucking.

[0129] Exemplarily, the side brush 160 may be located in front of the roller brush assembly 150 and close to the edge of the body 100. For example, the side brush 160 may be located at the edge of the left front or right front of the roller brush assembly, so that when the side brush 160 rotates, at least part of the side brush 160 is located outside the outline of the body 100. In this way, the side brush 160 can gather garbage outside the outline of the body 100 to the inside of the automatic cleaning device 10 to increase the cleaning range. The side brush 160 may be a rubber strip or a brush, etc., as long as it can gather garbage on the ground to the inside of the cleaning device 10, and is not limited here.

[0130] The outline of the fuselage 100 may be formed in a circular, D-shaped, rectangular, or other shape. The outline of the fuselage 100 refers to a circular outline, a D-shaped outline, or a rectangular outline of the fuselage 100. For example, Figure 1 and Figure 2 In the figure, the outline of the fuselage 100 is a circular structure; illustratively, the range of the outline of the fuselage 100 can be determined according to the projection of the fuselage 100 on the horizontal plane.

[0131] In some embodiments, the fuselage 100 includes a bottom shell 110, which provides support and installation basis for the structure arranged in the fuselage 100, wherein the bottom shell 110 can be made of metal or non-metallic material, and can be adaptively designed according to actual needs, which is not limited here.

[0132] In some embodiments, the body 100 also includes an upper shell (not shown in the figure), which is arranged on the bottom shell 110. The upper shell can be detachably connected to the bottom shell 110 by means of snap connection, threaded connection, snap connection, etc., so that the bottom shell 110 and the upper shell are jointly formed to form an installation cavity.

[0133] In some embodiments, please refer to Figures 1 to 12 As shown, the cleaning component 200 is disposed on the lower side of the bottom shell 110, wherein the lower side of the bottom shell 110 is, for example, along a direction perpendicular to the ground, the part above the bottom shell 110 is the upper side, and the side of the bottom shell 110 close to the ground is the lower side.

[0134] In some embodiments, the cleaning component 200 includes a driving unit 210 and a cleaning unit 220, wherein the cleaning unit 220 includes a cleaning piece 221, wherein the cleaning piece 221 is, for example, a cleaning cloth, so that the floor can be dry-mopped, wet-mopped, or the like by means of the cleaning piece 221; the driving unit 210 is configured to drive the cleaning piece 221 to move to perform a cleaning operation, for example, the driving unit 210 drives the cleaning piece 221 to reciprocate in a horizontal plane along the travel direction of the cleaning device 10 or the width direction of the body 100, or drives the cleaning piece 221 to swing back and forth between the travel direction and the width direction along, for example, a circular arc trajectory, so that the cleaning piece 221 is subjected to frictional force with the floor through vibration, and the area of ​​the vibration region of the cleaning piece 221 is increased to improve the cleaning effect.

[0135] In some embodiments, the cleaning device 10 also includes a lifting assembly 300, which is arranged on the upper side of the bottom shell 110, that is, the lifting assembly 300 is arranged in the installation cavity of the fuselage 100, so as to drive the cleaning assembly 200 to move along the first direction through the lifting assembly 300, so that the cleaning assembly 200 switches between a lifting position and a cleaning position, wherein the first direction has an angle with the surface to be cleaned, for example, the first direction is perpendicular or approximately perpendicular to the surface to be cleaned; the lifting position means that there is a gap between the cleaning member 221 and the ground, and the ground is not cleaned; and the cleaning position means that the cleaning member 221 is in contact with the ground, so that the ground is cleaned by the cleaning member 221, so that the user can switch the cleaning assembly 200 between the lifting position and the cleaning position according to needs, thereby improving the user's experience.

[0136] In the embodiment of the present application, when the lifting component 300 drives the cleaning component 200 to move along the first direction, it drives the cleaning unit 220 and the driving unit 210 to rise and fall synchronously. In this way, when the lifting component 300 drives the cleaning component 200 to move along the first direction, the position between the cleaning unit 220 and the driving unit 210 will not move relative to each other, thereby improving the position reliability between the driving unit 210 and the cleaning unit 220 in the first direction, and further improving the reliability of the driving unit 210 driving the cleaning member 221 to move for cleaning operations.

[0137] In order to improve the structural compactness of the cleaning device 10, in an embodiment of the present application, the driving unit 210 is arranged above the cleaning unit 220. Exemplarily, the projection of the driving unit 210 on the ground and the projection of the cleaning unit 220 on the ground at least partially overlap, so that the layout of the cleaning device 10 in the horizontal plane can be made more compact, thereby improving the space utilization of the cleaning device 10; wherein the horizontal plane is, for example, a plane perpendicular to the first direction.

[0138] Exemplarily, the driving unit 210 is connected to the cleaning unit 220 to drive the cleaning member 221 to reciprocate, etc. The lifting assembly 300 can be connected only to the cleaning unit 220, that is, the lifting assembly 300 can be not connected to the driving unit 210. The driving unit 210 is arranged above the cleaning member, so that when the lifting assembly 300 drives the cleaning unit 220 to move along the first direction, the cleaning unit 220 drives the driving unit 210 to rise and fall synchronously along the first direction. In this way, the connection relationship between the lifting assembly 300 and the driving unit 210 is simplified. At the same time, when the driving unit 210 and the cleaning unit 220 are lifted and lowered, the positions of the two in the first direction may not change, thereby improving the reliability of the relative positions of the driving unit 210 and the cleaning unit 220 in the first direction, and the stability of the connection between the driving unit and the cleaning unit, thereby improving the stability of the driving unit when driving the cleaning unit to reciprocate and reducing the generation of vibration noise.

[0139] In some embodiments, the projections of the drive unit 210 and the lifting assembly 300 in the first direction at least partially overlap, so that the structure of the cleaning device 10 in the horizontal plane can be further made more compact, so as to improve the utilization of space, optimize the internal spatial layout of the cleaning device 10, and reduce the outline size of the cleaning device 10, wherein the outline size of the cleaning device 10 refers to the area of ​​the projected outline on the ground.

[0140] In some embodiments, the bottom shell 110 is provided with a accommodating cavity 111, and the accommodating cavity 111 has an opening toward one side of the driving unit 210, and the driving unit 210 is arranged in the accommodating cavity 111. In this way, the space utilization of the cleaning device 10 in the first direction can be improved, and the thickness of the cleaning device 10 in the first direction can be reduced; in addition, the hollow structure in the accommodating cavity 111 can reduce the weight of the cleaning device 10, so that the cleaning device 10 develops in the direction of being small and light, so as to improve the user's experience.

[0141] Among them, the contour structure of the accommodating cavity 111 can match the contour structure of the driving unit 210, so that the accommodating cavity 111 has sufficient space to accommodate the driving unit 210, and there is no waste of space, so that the driving unit 210 can be accommodated in the accommodating cavity 111 and lifted and lowered along the first direction to improve the space utilization of the cleaning equipment 10.

[0142] In order to ensure that the cleaning component 200 has sufficient lifting space when moving along the first direction and to further improve the utilization of space, in an embodiment of the present application, a protrusion 112 is provided on the bottom shell 110, and the protrusion 112 is hollow inside to form a accommodating cavity 111, so that the driving unit 210 has sufficient lifting space when moving along the first direction, and the protrusion 112 protrudes toward the installation cavity of the body 100, so that the thickness dimension of the cleaning device 10 in the first direction will not be additionally increased.

[0143] In some embodiments, please refer to Figure 3 As shown, at least part of the structure of the lifting assembly 300 is located above the protrusion 112, and the projections of the lifting assembly and the protrusion 112 in the first direction at least partially overlap. In this way, the space between the protrusion 112 and the top of the installation cavity of the fuselage 100 can be further utilized, thereby improving the structural compactness of the cleaning device 10 in the horizontal direction, improving the space utilization, and reducing the overall outline size of the cleaning device 10.

[0144] In addition, a dust collection component is also provided in the body 100, and the dust collection component includes a dust box. A dust suction port 120 connected to the dust box is provided on the bottom shell 110 in the body 100. In this way, when the cleaning device 10 is in operation, the negative pressure generating device can provide negative pressure wind force into the dust box to absorb and collect garbage on the ground into the dust box through the dust suction port 120. Exemplarily, the dust suction port 120 is arranged at the bottom of the bottom shell 110 near the roller brush, so that the roller brush can roll the garbage on the ground to the dust suction port 120, and collect the garbage at the dust suction port 120 into the dust box through the negative pressure wind force.

[0145] In order to further improve the space utilization of the cleaning device 10, the dust box is arranged in the installation cavity of the body 100. For example, the length direction of the dust box is larger than the width direction, so that the length direction of the dust box is consistent with the width direction of the cleaning device 10, so that at least part of the dust box is located above the roller brush assembly 150 in the first direction, so as to optimize the spatial layout of the cleaning device 10 and ensure the space for the dust box to accommodate garbage without increasing the outline size of the cleaning device 10.

[0146] In addition, when the cleaning device 10 returns to the base station, in order to automatically remove the garbage in the dust box, in the embodiment of the present application, the dust collection component is connected to the dust box through a dust exhaust channel. When the cleaning device 10 returns to the base station, the dust exhaust channel can be connected to the negative pressure generating device in the base station. In this way, when the cleaning device 10 returns to the base station, when the negative pressure generating device is running, negative pressure adsorption wind can be provided to the dust box through the dust exhaust channel, so that the garbage in the dust box is discharged through the dust exhaust channel by the negative pressure adsorption wind, thereby achieving the purpose of automatically cleaning the dust box, without the need for manual cleaning of the dust box, thereby improving the user experience.

[0147] In order to improve the efficiency and cleaning effect of cleaning the dust box garbage, in an embodiment of the present application, the dust collection component also includes an air inlet channel, which is connected to the dust box. When the cleaning device 10 returns to the base station, the air inlet channel can be connected to the fan in the base station to provide blowing wind force to the dust box through the fan, so that the garbage in the dust box moves toward the side of the dust exhaust channel. In this way, the garbage in the dust box can be quickly discharged, thereby improving the efficiency and cleaning effect of cleaning the dust box.

[0148] In some embodiments, the body 100 is provided with a connecting channel 420 connecting the side wall of the body 100 and the dust box. The connecting channel 420 may include at least one of an air inlet channel and a dust exhaust channel. That is, at least one of the air inlet channel and the dust exhaust channel is connected between the side wall of the body 100 and the dust box, so as to facilitate further optimization and arrangement of the space of the body 100.

[0149] In some embodiments, at least the connecting section of the connecting channel 420 is higher than the driving unit 210 in the first direction. In this way, the space of the body 100 in the first direction can be further utilized, thereby improving space utilization and making the structure of the cleaning device 10 more compact.

[0150] Exemplarily, the lifting assembly 300 may be eccentrically disposed relative to the central axis S of the traveling direction of the cleaning device 10 to arrange the space in the installation cavity of the body 100 and improve the utilization of the space.

[0151] In some embodiments, please refer to Figure 3As shown, the connecting channel 420 includes a first connecting channel 421. The first connecting channel 421 and the lifting assembly 300 can be eccentrically arranged relative to the central axis S of the moving direction of the cleaning device 10, so that the first connecting channel 421 and the lifting assembly 300 are arranged according to the space of the fuselage 100 respectively. Without increasing the outline size of the cleaning device 10, the first connecting channel 421 and the lifting assembly 300 are arranged at suitable positions without affecting the performance and function of the cleaning device 10, thereby achieving the purpose of layout optimization and improving space utilization.

[0152] The first connecting channel 421 and the lifting assembly 300 may be located on the same side of the central axis S in the moving direction of the cleaning device 10 , or may be located on different sides, and the layout may be optimized according to the space of the body 100 .

[0153] Exemplarily, the first connecting passage 421 and the lifting assembly 300 are located on the same side of the central axis S in the travel direction of the cleaning device 10 to improve space utilization.

[0154] In order to further improve the layout optimization of the space, in some embodiments, the first connecting channel 421 and the lifting assembly 300 can be arranged adjacent to each other in the first direction, wherein the second direction is perpendicular to the first direction, and the second direction is, for example, the width direction of the cleaning device 10, and the width direction of the cleaning device 10 can also be perpendicular to the moving direction of the cleaning device 10, so as to further improve the structural compactness of the cleaning device 10.

[0155] It should be noted that the first connecting channel 421 can be an air inlet channel or a dust exhaust channel. When the first connecting channel 421 is an air inlet channel, the dust exhaust channel can be set on the side wall of the fuselage 100, or on the bottom wall of the bottom shell 110 of the fuselage 100. For example, the dust suction port 120 on the bottom shell 110 can also be used as a dust exhaust channel. That is, when the cleaning device 10 is cleaning the floor, the dust suction port 120 can be used to absorb garbage on the floor into the dust box through the dust suction port 120, and when the cleaning device 10 returns to the base station, the dust suction port 120 can be used as a dust exhaust channel to discharge garbage in the dust box through the dust exhaust channel. When the dust suction port 120 is used as a dust exhaust channel, since the dust suction port 120 is set at the bottom of the bottom shell 110, the garbage can be discharged faster due to the effect of gravity, thereby improving the dust exhaust efficiency.

[0156] In other embodiments, the first connecting channel 421 and the lifting assembly 300 may be located on opposite sides of the central axis S in the travel direction of the cleaning device 10, so that the spatial layout of the cleaning device 10 can be further optimized according to specific circumstances to improve space utilization.

[0157] Among them, the first connecting channel 421 can be, for example, an air inlet channel or a dust exhaust channel. Schematically, the first connecting channel 421 is, for example, a dust exhaust channel. The dust exhaust channel and the lifting component 300 are respectively arranged on the opposite sides of the central axis S in the traveling direction of the cleaning device 10, so that the garbage in the dust box can be discharged through the dust exhaust channel under the action of negative pressure wind force, without the need for manual cleaning, thereby improving the space utilization rate while improving the degree of automation of the cleaning device 10 and enhancing the user experience.

[0158] It should be noted that when the first connecting channel 421 is a dust exhaust channel, that is, at least part of the dust exhaust channel is higher than the drive unit 210 in the first direction, and the air inlet channel can be connected between the side wall of the fuselage 100 and the dust box, the air inlet channel can also be set at the bottom of the bottom shell 110 and connected to the dust box, so that the wind enters the dust box through the bottom of the dust box. In this way, the garbage deposited at the bottom of the dust box can be moved to one end of the dust exhaust channel by the wind in the air inlet channel.

[0159] In some embodiments, the connecting channel 420 may further include a second connecting channel 422, and the second connecting channel 422 and the first connecting channel 421 are located on opposite sides of the central axis S in the traveling direction of the cleaning device 10. In this way, the space utilization rate of the fuselage 100 can be improved to further improve the structural compactness of the cleaning device 10.

[0160] Exemplarily, the first connecting channel 421 is a dust exhaust channel, and the second connecting channel 422 is an air inlet channel. In this way, a blowing and sucking connecting channel 420 is formed on the side wall of the fuselage 100, and the air inlet channel is connected to one end of the dust box, and the dust exhaust channel is connected to the other end of the dust box. In this way, air is blown into the dust box through the air inlet channel, so that the garbage in the dust box moves to one end of the dust exhaust channel, so as to avoid the existence of cleaning dead corners in the dust box, thereby improving the effect of cleaning garbage.

[0161] It can be understood that the first connecting channel 421 has an air inlet connected to the dust box, for example, the first connecting channel 421 is a dust exhaust channel, and the negative pressure wind force provided by the base station to the dust box through the dust exhaust channel enters the dust box through the air inlet, so as to rely on the negative pressure wind force to discharge the garbage in the dust box; in addition, the second connecting channel 422 has an air outlet connected to the dust box, for example, the second connecting channel 422 is an air inlet channel, and the air provided by the base station to the dust box through the air inlet channel enters the dust box through the air outlet of the second connecting channel 422, so that the garbage in the dust box moves to one side of the exhaust channel, wherein the air inlet and the air outlet are arranged at opposite ends of the dust box, so that the garbage in the dust box can be blown from one end of the air inlet channel to one end of the dust exhaust channel, avoiding cleaning dead corners, thereby improving the cleaning effect.

[0162] In this way, the airflow entering the dust box through the air outlet of the second connecting channel 422 and the adsorption force entering the dust box through the air inlet of the second connecting channel 422 can simultaneously carry the garbage in the dust box and discharge it through the second connecting channel 422, so that the garbage in the dust box can be completely removed from one end to the other. The cleaning method is simple and the cleaning effect is good.

[0163] In some embodiments, the cross-sectional size of the first connecting channel 421 is larger than the cross-sectional size of the second connecting channel 422 , so that larger solid waste in the dust box can be discharged smoothly through the first connecting channel 421 .

[0164] In addition, in order to further improve space utilization, the second connecting channel 422 can be connected to one end of the dust box along the edge of the body 100, that is, the path extended by the second connecting channel 422 can avoid other structures on the bottom shell 110 as long as it can be connected to the dust box.

[0165] In other embodiments, the gaps between the structures between the side walls of the body 100 and the dust box can be formed as air inlet channels, that is, a second connecting channel 422 connected to the dust box is not separately provided, but the air intake can enter the dust box through the gaps between adjacent structures on the bottom shell 110. In this way, the space of the second connecting channel 422 can be saved to improve space utilization.

[0166] In some embodiments, the lifting assembly 300 is located between the first connecting channel 421 and the second connecting channel 422 to optimize the layout of various structures in the fuselage 100 and improve the space utilization rate in the fuselage 100 .

[0167] In addition, the cleaning device 10 also includes a negative pressure device 500, which is, for example, a negative pressure fan. The negative pressure device 500 can be arranged between the first connecting channel 421 and the lifting assembly 300. The negative pressure device 500 provides negative pressure wind force to the dust box, so that when the cleaning device 10 cleans the floor, it can collect garbage and dust particles on the floor into the dust box through the dust suction port 120, and the method of collecting garbage and dust particles is simple; in addition, by respectively arranging the first connecting channel 421 and the second connecting ventilation on both sides of the negative pressure device 500, the space layout is optimized and the space utilization rate is improved.

[0168] Exemplarily, the negative pressure device 500 is disposed on the bottom shell 110 and in an area corresponding to the cleaning component 200. For example, the negative pressure device 500 is disposed in a direction close to the central axis S in the direction of travel of the cleaning component 200, and the negative pressure device 500 is located in an area close to the rear of the body 100 (i.e., the cleaning component 200), so that when the cleaning device 10 moves forward, the negative pressure device 500 forms a negative pressure wind force that moves from the dust suction port 120 to the inside of the dust box, that is, the wind force moves into the dust box through the dust suction port 120, so that the negative pressure wind force carries garbage and dust particles into the dust box.

[0169] In some embodiments, the bottom shell 110 has at least one water replenishment channel 113; the cleaning unit 220 also includes a supporting structure, and the cleaning element 221 is fixed on the supporting structure. A water outlet channel 228 connected to the water replenishment channel 113 is arranged at a position of the supporting structure corresponding to the water replenishment channel 113, and a first water outlet connected to the water outlet channel 228 is arranged on the side of the supporting structure facing the cleaning element 221 to replenish water to the cleaning element 221 through the first water outlet. In this way, by setting the water replenishment channel 113 on the bottom shell 110 to replenish water to the cleaning element 221, the cleaning element 221 is kept moist and the cleaning effect is improved.

[0170] In some embodiments, at least two water replenishment channels 113 are provided on the bottom shell 110, and along the second direction, at least two water replenishment channels 113 are respectively provided on opposite sides of the central axis S in the traveling direction of the cleaning device 10, and water outlet channels 228 are provided at positions corresponding to each water replenishment channel 113 on the supporting structure, and a first water outlet is provided at positions corresponding to each water outlet channel 228 on the side of the supporting structure facing the cleaning element 221. By providing at least two water replenishment channels 113 and making at least two water replenishment channels 113 respectively provided on opposite sides of the central axis S in the traveling direction of the cleaning device 10, the humidity of the cleaning element 221 can be made uniform, thereby improving the cleaning effect.

[0171] In some embodiments, please refer to Figure 2 and Figure 3 As shown, it also includes a water replenishment component, which is arranged on the bottom shell 110; the water replenishment component includes a clean water tank 600 and a water replenishment pipeline. For example, the clean water tank 600 is arranged on the bottom shell 110, one end of the water replenishment pipeline is connected to the clean water tank 600, and the other end of the water replenishment pipeline is connected to the water replenishment channel 113. The clean water tank 600 is configured to provide clean water to the water replenishment channel 113 through the water replenishment pipeline. In this way, the cleaning equipment 10 can replenish the cleaning part 221 with water through the clean water tank 600 carried by itself through the water replenishment pipeline and the water replenishment channel 113, without providing water to the water replenishment channel 113 from other places, thereby improving the convenience of water replenishment.

[0172] In some embodiments, the clean water tank 600 is disposed on a side of the first connecting passage 421 away from the second connecting passage 422 to optimize the layout of the space of the fuselage 100 and improve space utilization.

[0173] In some embodiments, the clean water tank 600 is disposed on the side of the first connecting channel 421 away from the second connecting channel 422, and is adjacent to the second connecting channel 422, and the clean water tank 600 is disposed at an edge position close to the fuselage 100, and a support base is provided for the clean water tank 600 through a position close to the edge of the bottom shell 110 to improve the utilization rate of the space in the fuselage 100.

[0174] In the embodiment of the present application, the lifting assembly 300 is arranged on the upper side of the bottom shell 110, and the cleaning assembly 200 is arranged on the lower side of the bottom shell 110, and the lifting assembly 300 drives the cleaning assembly 200 to move up and down as a whole, so as to improve the working reliability of the cleaning assembly 200; in addition, along the width direction of the fuselage 100, the first connecting channel 421 and the second connecting channel 422 are respectively arranged on opposite sides of the moving direction of the cleaning device 10, and the negative pressure device 500 and the lifting assembly 300 are arranged between the first connecting channel 421 and the second connecting channel 422, for example, from the first connecting channel 421 to the side of the second connecting channel 422, and its layout is, for example, the clean water tank 600, the first connecting channel 421, the negative pressure device 500, the lifting assembly 300, and the second connecting channel 422 in sequence, wherein these structures are not located on the same straight line, but can be staggered front and back in the moving direction of the fuselage 100, so as to further optimize the layout of each structure in the fuselage 100 and improve space utilization.

[0175] In addition, the water supply pipeline and the overflow pipeline can be set as hoses, so that they can be bent and laid out according to the flexibility of the hoses to improve space utilization and improve the compactness of the overall structure of the cleaning device 10.

[0176] In some embodiments, the water replenishment component also includes an overflow pipe, and the clean water tank 600 has an overflow port 610; a first overflow channel 114 is provided on the bottom shell 110 and passes through the bottom shell 110, one end of the overflow pipe is connected to the overflow port 610, and the other end of the overflow pipe is connected to the first overflow channel 114, and a second overflow channel 229 is provided at a position corresponding to the first overflow channel 114 on the supporting structure, and a second water outlet is provided on the side of the second overflow channel 229 facing the cleaning member 221. By arranging the overflow port 610 on the clean water tank 600, when the water in the clean water tank 600 exceeds a preset height, the overflowing water can overflow through the overflow port 610 and drip onto the cleaning member 221 through the second water outlet, thereby avoiding the problem of water leakage in the clean water tank 600.

[0177] It is understandable that when the road surface on which the cleaning equipment 10 travels is uneven and has an inclined angle, the water in the clean water tank 600 may overflow from the top due to the local water level being too high, or the water in the clean water tank 600 may be too full and cause overflow. In order to avoid the water in the clean water tank 600 from overflowing, in an embodiment of the present application, an overflow port 610 is provided at a preset height position of the clean water tank 600. When the water surface reaches the overflow port 610, the water will enter the overflow pipe through the overflow port 610 and drip toward the cleaning element 221 through the second water outlet, so as to humidify the cleaning element 221 while avoiding the problem of water leakage in the clean water tank 600.

[0178] In some embodiments, the overflow pipe is arranged on one side of the bottom shell 110 close to the first connecting channel 421. In this way, the pipe distance between the overflow pipe and the clean water tank 600 can be shortened, and the water overflowing from the clean water tank 600 can be discharged in time through the overflow pipe, thereby avoiding the problem of water leakage in the clean water tank 600.

[0179] In some embodiments, a first groove is provided on the circumference of one end of the water outlet channel 228 facing the bottom shell 110, and the projection of the first groove in the first direction covers the projection of the water replenishment channel 113. For example, the projection of the first groove in the first direction is larger than the projection of the water outlet channel 228 in the first direction. In this way, when the water in the water replenishment channel 113 drips into the water outlet channel 228, as long as the water dripped from the water replenishment channel 113 is within the range of the first groove, it is sufficient, thereby reducing the alignment accuracy between the water replenishment channel 113 and the water outlet channel 228 and reducing the equipment cost.

[0180] In addition, a second groove may also be provided in the circumference of one end of the second overflow channel 229 facing the bottom shell 110, and the projection of the second groove in the first direction is larger than the projection of the first overflow channel 114. In this way, when the water from the first overflow channel 114 drips into the second overflow channel 229, as long as the water dripping from the first overflow channel 114 is within the range of the second groove, it is sufficient, thereby reducing the alignment accuracy between the first overflow channel 114 and the second overflow channel 229 and reducing the equipment cost.

[0181] In some embodiments, a first guide groove 115 and a second guide groove 116 are respectively provided on the bottom shell 110, and at least part of the water replenishment pipeline is located in the first guide groove 115 and extends to the water replenishment channel 113; at least the water replenishment of the overflow pipeline is located in the second guide groove 116 and extends to the overflow channel, so that the water replenishment pipeline and the overflow pipeline are respectively guided by the first guide groove 115 and the second guide groove 116 to optimize the spatial layout and improve space utilization.

[0182] In some embodiments, the support structure includes a power transmission member 222, a cleaning member 221 is fixed to the power transmission member 222, and the driving unit 210 is configured to drive the power transmission member 222 to reciprocate so that the cleaning member 221 cleans the surface to be cleaned. The cleaning member 221 is, for example, a cleaning cloth, so that the cleaning member 221 can be used to perform dry mopping, wet mopping, and other operations on the floor.

[0183] It can be understood that by driving the power transmission member 222 to reciprocate through the driving unit 210, friction force can be exerted between the cleaning member 221 and the ground to increase the cleaning effect.

[0184] Among them, the driving unit 210 can drive the power transmission component 222 to perform reciprocating motion within a preset motion trajectory. The reciprocating motion can be, for example, reciprocating motion along a straight line in one direction, or reciprocating swinging along an arc line in two or more directions, etc., and can be adaptively set according to actual needs.

[0185] When the cleaning device 10 moves forward, the driving unit 210 drives the power transmission component 222 to vibrate by reciprocating motion or the like, so that the cleaning component 221 is subjected to frictional force with the ground. Since the power transmission component 222 is connected to the driving unit 210 and moves relative to the body 100, the power transmission component 222 may be tilted relative to the body 100 and contact the body 100 during vibration, resulting in poor stability of the power transmission component 222 during vibration, and there is a problem that the vibration of the power transmission component 222 is transmitted to the entire cleaning device 10 and causes resonance.

[0186] Therefore, in order to improve the stability of the driving unit 210 when driving the power transmission member 222 to reciprocate and avoid the power transmission member 222 from tilting when vibrating, please refer to Figure 4 As shown, in the embodiment of the present application, the cleaning device 10 also includes a fixing part 130, which is fixed relative to the body 100, and the power transmission part 222 is movably connected to the fixing part 130, so that the driving unit 210 and the fixing part 130 are respectively connected to the power transmission part 222, that is, there is a connection point between the driving unit 210 and the power transmission part 222, and there is also a connection point between the fixing part 130 and the power transmission part 222. In this way, the two connection points can improve the support stability of the power transmission part 222, and can avoid the driving unit 210 driving the power transmission part 222 to move back and forth. When the power transmission part 222 is tilted or moved outside the motion trajectory, the movement smoothness of the power transmission part 222 is improved, and the vibration of the power transmission part 222 can be avoided. The problem of resonance of the whole machine caused by the vibration of the power transmission part 222 being transmitted to the whole machine can be avoided, and the vibration noise can be reduced, and the user's experience is improved.

[0187] In some embodiments, the power transmission member 222 may be a vibration plate, and the cleaning member 221 may be, for example, a cleaning cloth. The cleaning cloth may be fixed to the side of the vibration plate facing the surface to be cleaned by gluing or the like.

[0188] Exemplarily, the projection of the cleaning member 221 on the surface to be cleaned covers the projection of the power transmission member 222 on the surface to be cleaned, so that the cleaning efficiency is increased by increasing the area of ​​the cleaning member 221 .

[0189] In the embodiment of the present application, the vibration of the power transmission member 222 is utilized to cause the cleaning member 221 to be subjected to frictional force with the surface to be cleaned. In this way, the area of ​​the vibration region of the power transmission member 222 determines the mopping effect. The larger the vibration region of the power transmission member 222, the better the mopping effect. The driving unit 210 drives the power transmission member 222 to vibrate as a whole. Therefore, the larger the outline size of the power transmission member 222, the better the mopping effect of the power transmission member 222 and the higher the mopping efficiency.

[0190] In some embodiments, the driving unit 210 is configured to drive the power transmission member 222 to swing back and forth relative to the fixing member 130. Exemplarily, the driving unit 210 can drive the power transmission member 222 to swing back and forth along a preset arc trajectory on a horizontal plane relative to the fixing member 130, so that when the cleaning device 10 is moving forward, the power transmission member 222 swings back and forth along a preset arc trajectory on a horizontal plane relative to the fixing member 130, which can increase the cleaning range of the cleaning member 221, and the power transmission member 222 drives the cleaning member 221 to move in a reciprocating swinging manner, which can repeatedly mop the ground to improve the cleaning effect; in addition, the power transmission member 222 swings back and forth relative to the fixing member 130, and has good stability.

[0191] In some embodiments, please refer to Figure 8 As shown, the fixing member 130 defines a first rotation axis M, and the power transmission member 222 is rotationally connected to the fixing member 130 around the first rotation axis M, wherein the first rotation axis M and the surface to be cleaned have an angle; illustratively, the fixing member 130 is, for example, a rotating shaft, and the central axis of the rotating shaft forms the first rotation axis M, and the first rotation axis M and the surface to be cleaned are, for example, perpendicular to each other, so that the power transmission member 222 is rotationally connected to the fixing member 130, and the fixing member 130 supports the power transmission member 222, and under the driving force of the driving unit 210, the power transmission member 222 swings back and forth around the first rotation axis M, so that the movement of the power transmission member 222 in each direction within the range of the motion trajectory is uniform, so as to further improve the stability of the power transmission member 222 during movement.

[0192] Exemplarily, the first rotation axis M is perpendicular to the ground. Under the action of an external driving force, the power transmission member 222 swings back and forth around the first rotation axis M within a preset arc range in the horizontal plane relative to the fixed member 130, so that the movement of the power transmission member 222 in, for example, the forward direction of the fuselage 100 (for example, the X direction) and the width direction of the fuselage 100 (for example, the Y direction) is uniform, so as to improve the stability of the power transmission member 222 during reciprocating motion.

[0193] Exemplarily, the fixing member 130 is, for example, a rotating shaft, which can be fixedly connected to the body 100 by, for example, threaded connection or the like.

[0194] In addition, in order to improve the rotation smoothness between the power transmission member 222 and the fixed member 130, in the embodiment of the present application, a bearing can be arranged between the fixed member 130 and the power transmission member 222, the bearing is sleeved on the fixed member 130, and the power transmission member 222 is connected to the bearing; exemplarily, the bearing includes an inner ring, an outer ring and a rolling body, the rolling body is arranged between the inner ring and the outer ring, the inner ring is sleeved on the fixed member 130 and is fixedly connected to the fixed member 130, and the first rotation axis M of the bearing and the fixed member 130 is coaxially arranged, and the outer ring is connected to the power transmission member 222. 222 is fixedly connected, and the outer ring and the inner ring can rotate relative to each other. In this way, under the action of external driving force, the power transmission member 222 rotates around the first rotation axis M relative to the fixed member 130 through the bearing, thereby improving the smoothness of the reciprocating swing of the power transmission member 222 around the first rotation axis M, and can avoid the wear of the fixed member 130 or the power transmission member 222 due to friction between the power transmission member 222 and the fixed member 130, thereby affecting the accuracy of power transmission, and can also avoid the problem of movement jamming due to high friction between the power transmission member 222 and the fixed member 130.

[0195] In some embodiments, there is a gap between the connection point between the driving unit 210 and the power transmission component 222 and the first rotation axis M, so that the power transmission component 222 can be supported by the connection points at two positions of the driving unit 210 and the first rotation axis M respectively, thereby improving the stability of the power transmission component 222 during movement.

[0196] Exemplarily, the power transmission member 222 is a vibration plate, and the first rotation axis M is arranged at the center position of the power transmission member 222. For example, the first rotation axis M is arranged at the center position of the power transmission member 222 in the width direction and the length direction, and the driving unit 210 is eccentrically arranged relative to the first rotation axis M. In this way, the power transmission member 222 can be supported by the connection points of the driving unit 210 and the first rotation axis M respectively, so as to improve the stability of the power transmission member 222 during movement; in addition, by eccentrically arranging the driving unit 210 and the first rotation axis M at the center position of the power transmission member 222, in this way, a smaller driving force can be used to drive the power transmission member 222 to swing back and forth around the first rotation axis M, which saves time and effort, and the driving unit 210 can adopt a smaller driving power, thereby reducing driving energy consumption.

[0197] In some embodiments, please refer to Fig.11 and Fig.12 As shown, the drive unit 210 includes a drive motor 211 and a drive member 212. Exemplarily, the drive motor 211 is, for example, a brushless motor; the output shaft of the drive motor 211 is connected to the drive member 212, for example, the output shaft of the drive connection is fixedly connected to the drive member 212, so that the output shaft of the drive motor 211 can drive the drive member 212 to move, so that the drive member 212 drives the power transmission member 222 to swing back and forth around the first rotation axis M, so that the vibration frequency of the power transmission member 222 is consistent with the rotation frequency of the brushless motor to improve the cleaning effect.

[0198] It can be understood that in the embodiment of the present application, the power of the drive motor 211 is transmitted to the power transmission member 222 through the driving member 212 to drive the power transmission member 222 to swing back and forth around the first rotation axis M, so as to realize the twisting movement of the power transmission member 222 around the first rotation axis M in the horizontal plane, so as to increase the vibration area of ​​the power transmission member 222 and improve the mopping and cleaning effect of the cleaning member 221.

[0199] In some embodiments, the driving motor 211 drives the driving member 212 to rotate around the second rotation axis N, and the driving member 212 has a driving portion 2121 eccentrically arranged relative to the second rotation axis N, and the driving portion 2121 is connected to the power transmission member 222, wherein the second driving axis is spaced apart and arranged in parallel with the first rotation axis M. Exemplarily, the second rotation axis N can be, for example, the central axis of the output shaft of the driving motor 211.

[0200] It can be understood that by eccentrically arranging the driving part 2121 relative to the second rotation axis N (as shown in 12), under the driving force of the driving motor 211, the driving part 2121 rotates eccentrically relative to the second rotation axis N. Since the driving part 2121 is connected to the power transmission member 222, the power transmission member 222 is driven to swing back and forth with the fixing member 130 as a rotation support. The implementation method is simple. In addition, while the driving member 212 drives the power transmission member 222 to vibrate, the vibration stability of the power transmission member 222 is improved.

[0201] In some embodiments, the driving member 212 includes a driving body 2122 extending axially along the output shaft, and the driving portion 2121 is connected to one end of the driving body 2122. That is, the output shaft of the driving motor 211 is fixedly connected to the driving body 2122, and the driving portion 2121 is eccentrically arranged at one end of the driving body 2122, so that the driving motor 211 can drive the driving portion 2121 to rotate eccentrically through the driving body 2122, and drive the power transmission member 222 to swing back and forth through the driving portion 2121 to achieve vibration. The structure is simple and easy to implement.

[0202] In some embodiments, the driving body 2122 has an axial hole 2123, and the output shaft is passed through the axial hole 2123 to connect the driving member 212; wherein the output shaft of the driving motor 211 is relatively fixedly connected to the driving body 2122. Exemplarily, the output shaft is arranged in the axial hole 2123, and can be connected by, for example, interference fit connection, key connection, etc., wherein the key connection is, for example, a flat key connection, a spline connection, etc., as long as the driving body 2122 and the output shaft can be relatively fixed, so that the output shaft drives the driving body 2122 to move synchronously, there is no limitation here.

[0203] It can be understood that in the embodiment of the present application, by setting the driving body 2122 to an axial hole 2123 structure that matches the output shaft, the output shaft is passed through the axial hole 2123 to achieve the connection between the output shaft and the driving member 212. The structure is simple, easy to implement and low in cost.

[0204] In some embodiments, the driving portion 2121 is a convex column, one end of which is connected to the driving body 2122, and the other end extends in a direction away from the driving body 2122, so as to drive the power transmission member 222 to move through the convex column, thereby achieving power transmission and having a simple structure.

[0205] Exemplarily, the driving portion 2121 is a convex column structure with a circular cross-section. For example, the driving portion 2121 is a driving shaft, which is fixedly connected to the power transmission member 222 to drive the power transmission member 222 to vibrate. The driving portion 2121 has a simple structure, is easy to process, and has low cost.

[0206] In addition, the driving body 2122 can also be a convex column structure with a circular cross-section. For example, the driving body 2122 is a cylindrical rotating part 320. In this way, the driving part 2121 is eccentrically arranged at one end of the driving body 2122 away from the driving motor 211. The driving body 2122 is fixedly connected to the output shaft so that when the output shaft rotates, the driving part 2121 is driven to rotate eccentrically through the driving body 2122, thereby making the reciprocating motion of the power transmission part 222 to realize vibration.

[0207] In some embodiments, the driving body 2122 and the driving part 2121 can be formed into an integral structure by injection molding or casting, which can simplify the preparation process, reduce the installation process, and thus reduce costs.

[0208] In some embodiments, a connecting member 213 is further included. The connecting member 213 is fixedly connected to the driving portion 2121 . The connecting member 213 has a connecting portion 2131 eccentrically arranged relative to the driving portion 2121 . The connecting portion 2131 is fixedly connected to the power transmission member 222 .

[0209] In the embodiment of the present application, a connecting member 213 is provided between the driving part 2121 and the power transmission member 222 so as to change the connection point between the driving member 212 and the power transmission member 222 through the connecting member 213, thereby changing the torque between the driving member 212 and the power transmission member 222. In this way, the power transmission member 222 can be driven to reciprocate by a smaller driving force, so as to achieve the purpose of saving driving force, so that the power transmission member 222 can be driven to vibrate by using a smaller driving power, thereby achieving the purpose of saving driving energy consumption.

[0210] In some embodiments, the connecting member 213 includes a connecting body 2132 extending along the extension direction of the driving portion 2121, and the connecting portion 2131 is connected to one side of the connecting body 2132 so that there is an inclined angle between the connecting portion 2131 and the width direction of the cleaning device 10. In this way, the connecting body 2132 is fixedly connected to the driving portion 2121, and the connecting portion 2131 is eccentrically arranged on one side of the connecting body 2132, so that the connecting portion 2131 is fixedly connected to the power transmission member 222 to change the torque between the power transmission member 222 and the driving portion 2121, so that a smaller driving force can be used to drive the power transmission member 222 to move, thereby reducing the energy consumption of the driving motor 211.

[0211] In some embodiments, the connecting body 2132 is, for example, a sleeve, which is sleeved on the driving part 2121, wherein the sleeve can be relatively fixed with the driving part 2121 by, for example, interference fit, key connection, etc., and the connection method is simple and easy to install.

[0212] Exemplarily, the connecting portion 2131 includes a connecting arm and a connecting shaft arranged on the connecting arm, one end of the connecting arm is connected to the side wall of the sleeve, the connecting shaft is connected to the side of the connecting arm away from the sleeve, and the connecting shaft extends in a direction perpendicular to the surface of the power transmission member 222 so as to be fixedly connected to the power transmission member 222 through the connecting shaft, wherein the connecting shaft can be fixed to the power transmission member 222 by means of interference fit or threaded connection, so that the driving portion 2121 can drive the power transmission member 222 to vibrate through the connecting member 213.

[0213] In some embodiments, please refer to Figures 7 to 11 As shown, the support structure also includes a top plate 223 and a bottom plate 224, and the power transmission member 222 is movably arranged between the top plate 223 and the bottom plate 224. An avoidance opening 2241 is arranged at a position of the bottom plate 224 corresponding to the power transmission member 222, and the avoidance opening 2241 is used to avoid the movement trajectory of the power transmission member 222. Exemplarily, the avoidance opening 2241 is used to expose the power transmission member 222, and there is a gap between the mouth wall of the avoidance opening 2241 and the edge of the power transmission member 222. In addition, a cleaning member 221 can be arranged on the surface of the bottom plate 224 facing the cleaning surface and on the surface of the power transmission member 222. In this way, the area of ​​the cleaning member 221 can be increased, wherein the cleaning member 221 fixed on the bottom plate 224 and the power transmission member 222 can be independent or an integrated structure, and can be adaptively arranged according to actual needs.

[0214] In the embodiment of the present application, by setting the power transmission component 222 between the top plate 223 and the bottom plate 224, the driving unit 210 only drives the power transmission component 222 to move, the top plate 223 and the bottom plate 224 do not vibrate relative to the body 100, and the power transmission component 222 will not collide with the bottom plate 224 and the top plate 223 due to vibration, thereby reducing the vibration of the entire cleaning device 10, reducing vibration noise, and improving the user's experience; and by setting the cleaning component 221 on the bottom plate 224 and the power transmission component 222 to increase the area of ​​the cleaning component 221, the cleaning efficiency can be improved.

[0215] In some embodiments, the projection area of ​​the avoidance opening 2241 in the first direction is larger than the projection area of ​​the power transmission component 222 in the first direction; wherein the first direction is perpendicular to the surface to be cleaned. In this way, interference between the power transmission component 222 and the bottom plate 224 during vibration to avoid motion jamming or collision noise can be avoided, thereby improving the movement comfort of the vibration transmission component and reducing vibration noise.

[0216] Exemplarily, the contour shape of the avoidance opening 2241 matches the contour shape of the power transmission component 222. In this way, the aesthetics of the cleaning device 10 can be improved while increasing the area of ​​the power transmission component 222, so that the cleaning component 221 has a larger area to clean the surface to be cleaned, thereby improving the cleaning efficiency.

[0217] That is to say, the contour shape of the avoidance opening 2241 is basically the same as the contour shape of the power transmission component 222, and the projection area of ​​the avoidance opening 2241 in the first direction is larger than the projection area of ​​the power transmission component 222 in the first direction, so that the avoidance opening 2241 can avoid the movement trajectory of the power transmission component 222 while improving the aesthetics of the entire machine.

[0218] In addition, the surface of the power transmission member 222 facing the surface to be cleaned can be flush with the surface of the bottom plate 224 facing the cleaning surface. In this way, the cleaning member 221 fixed on the power transmission member 222 and the bottom plate 224 can be flat in the horizontal plane, thereby improving the cleaning effect; in addition, the bottom plate 224 and the power transmission member 222 can be attached to the cleaning member 221 by adhesives (such as Velcro), and the cleaning member 221 is, for example, a cleaning cloth. In this way, the flatness of the cleaning cloth attached to the bottom plate 224 and the vibration transmission member can be ensured, so that the vibration transmission member cleans the floor when driving the cleaning member 221 to vibrate.

[0219] While ensuring other functions and performances of the cleaning device 10, the area of ​​the power transmission member 222 is increased as much as possible to increase the vibration area of ​​the power transmission member 222 and improve the mopping effect and efficiency.

[0220] In some embodiments, a water outlet channel 228 is provided on the top plate 223 and the power transmission member 222, and the water outlet channel 228 has a first water outlet at one end facing the cleaning member 221. In this way, water or other liquids can pass through the water outlet channel 228 and drip onto the cleaning member 221 through the first water outlet to replenish water for the cleaning member 221, so that the cleaning member 221 can mop the ground in a wet or humid state to form wet cleaning and improve the cleaning effect.

[0221] In order to maintain uniform wetness of the cleaning member 221, in an embodiment of the present application, a plurality of water outlet channels 228 may be provided, and the plurality of water outlet channels 228 evenly and spacedly penetrate the top plate 223 and the power transmission member 222, wherein each water outlet channel 228 is provided with a first water outlet to make the humidity of the cleaning member 221 uniform and to improve the cleaning effect.

[0222] Exemplarily, with the central axis S in the width direction of the power transmission member 222 as the center of symmetry, a plurality of water outlet channels 228 are symmetrically arranged on opposite sides of the central axis S, so that the humidity on opposite sides of the central axis S is kept uniform.

[0223] Correspondingly, one or more water replenishment pipelines may be provided. For example, one water replenishment pipeline may be provided. In this way, the water replenishment pipeline may be respectively connected to multiple water outlet channels 228 to supply water to each water outlet channel 228, so that the water outlet channels 228 replenish water to the cleaning element 221 through each first water outlet to maintain the wetness of the cleaning element 221; or, there may be multiple water replenishment pipelines, wherein one water replenishment pipeline corresponds to one water outlet pipeline. In this way, the cleaning element 221 may be replenished with water through multiple water replenishment pipelines at the same time, or one or more of the multiple water replenishment pipelines may be opened to replenish water to a part of the cleaning element 221. The specific configuration may be adaptively performed according to actual needs.

[0224] It can be understood that each water supply pipeline has an openable and closable valve. When the valve is open, the water in the clean water tank 600 can be supplied to the water outlet channel 228 through the water supply pipeline. When the valve is closed, the water supply pipeline is blocked. In addition, the cleaning device 10 can be provided with a humidity detection sensor to detect the humidity of the cleaning part 221 through the humidity detection sensor. When the humidity of the cleaning part 221 is detected to be low, a signal can be transmitted to the controller or pan / tilt head of the cleaning device 10 to control the valve to open to replenish water to the cleaning part 221.

[0225] In addition, a second overflow channel 229 is provided on the top plate 223 and the power transmission member 222, which passes through the top plate 223 and the power transmission member 222 in sequence. The second overflow channel 229 has a second water outlet at one end facing the cleaning member 221. When the liquid level of the clean water tank 600 is higher than a preset height, the overflowing water in the clean water tank 600 can pass through the second overflow channel 229 and drip onto the clean water member through the second water outlet. In this way, the problem of overflow and leakage of the clean water tank 600 can be prevented, thereby improving the user experience.

[0226] Exemplarily, the second overflow channel 229 is arranged on a side close to the clean water tank 600, so that the length of the pipe between the overflow channel and the clean water tank 600 can be shortened, so that the water overflowing from the clean water tank 600 can be discharged through the overflow channel in time, avoiding the problem of water leakage from the water tank mouth and affecting the performance of the cleaning equipment 10.

[0227] In order to reduce the problem of vibration noise generated by vibration transmission when the power transmission member 222 vibrates, in the embodiment of the present application, the power transmission member 222 has at least two first elastic buffer members 225 arranged at intervals in the circumferential direction, and the first elastic buffer member 225 is connected between the power transmission member 222 and the top plate 223. By arranging the first elastic buffer member 225 between the circumference of the power transmission member 222 and the top plate 223, on the one hand, a corresponding gap is provided between the power transmission member 222 and the top plate 223 to avoid contact between the top plate 223 and the power transmission member 222, thereby avoiding the vibration of the power transmission member 222 being transmitted to the top plate 223 and causing vibration noise; on the other hand, the first elastic buffer member 225 can limit and reset the power transmission member 222, so that the power transmission member 222 moves along the motion trajectory, thereby improving the motion reliability of the power transmission member 222 during movement.

[0228] The first elastic buffer 225 is made of a material having elasticity and vibration absorption functions, such as silicone or rubber. In addition, the first elastic buffer 225 also has a certain strength, which is not specifically limited here.

[0229] Exemplarily, there are four first elastic buffer members 225, and the four first elastic buffer members 225 are respectively spaced apart around the power transmission member 222 and connected between the top plate 223 and the power transmission member 222. In this way, the power transmission member 222 can be further limited within the range of the motion trajectory, while improving the connection reliability between the top plate 223 and the power transmission member 222, and preventing the power transmission member 222 from transmitting vibration to the top plate 223 and causing vibration noise, thereby improving the user experience.

[0230] In some embodiments, the first elastic buffer 225 includes a first elastic fixing portion 2251, a second elastic fixing portion 2252 and an elastic connecting portion 2253. The first elastic fixing portion 2251 is fixedly connected to the top plate 223, the second elastic fixing portion 2252 is fixedly connected to the power transmission member 222, and the elastic connecting portion 2253 is connected between the first elastic fixing portion 2251 and the second elastic fixing portion 2252. In this way, the connection reliability between the first elastic buffer 225 and the top plate 223 and the power transmission member 222 is improved, while avoiding hard contact between the power transmission member 222 and the top plate 223, which can reduce the transmission of vibration and thus reduce vibration noise.

[0231] Exemplarily, the first elastic fixing portion 2251 and the second elastic fixing portion 2252 can be connected to the top plate 223 respectively through at least two threaded connectors 900, so that the connection reliability between the first elastic fixing portion 2251 and the second elastic fixing portion 2252 and the top plate 223 can be further improved.

[0232] In some embodiments, the elastic connection portion 2253 includes at least two elastic strips, at least two elastic strips are arranged at intervals, and the two ends of each elastic strip are respectively connected to the first elastic fixing portion 2251 and the second elastic fixing portion 2252. By setting the elastic connection portion 2253 as at least two elastic strips, the two ends of the elastic strip are respectively connected between the first elastic fixing portion 2251 and the second elastic fixing portion 2252. In this way, while improving the elastic buffering effect, the structure is simple, easy to implement, and low in cost.

[0233] In some embodiments, the first elastic fixing portion 2251, the second elastic fixing portion 2252 and the elastic connecting portion 2253 can be formed into an integrated structure by an injection molding process, so that the installation process can be reduced, thereby reducing the process cost.

[0234] In some embodiments, the power transmission member 222 and the base plate 224 are also provided with a second elastic buffer member 226 in the first direction to reduce the vibration transmission between the power transmission member 222 and the base plate 224 through the second elastic buffer member 226, thereby reducing vibration noise.

[0235] Exemplarily, the power transmission member 222 is provided with a plurality of second elastic buffer members 226 arranged at intervals along its circumference, wherein the circumference of the power transmission member 222 refers to the extension direction along the contour of the power transmission member 222, and a plurality of second elastic buffer members 226 are arranged at intervals outside the contour of the power transmission member 222 to avoid vibration noise caused by hard contact between the power transmission member 222 and the bottom plate 224; in addition, the second elastic buffer members 226 can also make the power transmission member 222 located in the same height plane, thereby improving the flatness of the power transmission member 222, so that the cleaning member 221 is located in the same plane to improve the cleaning effect.

[0236] In some embodiments, the second elastic buffer member 226 includes one of an elastic buffer pad and an elastic buffer block, which has a simple structure, is easy to process and manufacture, and has low cost.

[0237] Exemplarily, the second elastic buffer 226 is, for example, a long strip of buffer pad, and the second elastic buffer 226 extends along the contour extension direction of the power transmission member 222 to increase the circumferential elastic support area of ​​the power transmission member 222 and improve vibration absorption and support reliability.

[0238] In addition, the second elastic buffer 226 can also be made of a material such as silicone, rubber, etc. that has a certain elasticity and vibration absorption function, and also has a certain strength, so as to be supported between the base plate 224 and the vibration transmission component through the second elastic component to avoid contact between the vibration transmission component and the base plate 224.

[0239] In some embodiments, at least two first elastic buffer members 225 and at least two second elastic buffer members 226 are alternately arranged in sequence along the circumference of the power transmission member 222 to jointly improve the elastic support for the power transmission member 222, improve the stability of the power transmission member 222, reduce the transmission of vibration, and reduce vibration noise.

[0240] In some embodiments, please refer to Figures 2 to 6 As shown, it also includes a lifting component 300, which is arranged in the body 100. The lifting component 300 is constructed to drive the cleaning component 200 to move along a first direction, so that the cleaning component 200 can switch between a lifting position and a cleaning position. For example, when the cleaning member 221 is not needed to mop the floor, the lifting component 300 can drive the cleaning component 200 to move to the lifting position, so that there is a certain gap between the cleaning member 221 and the ground; and when the cleaning component 200 is needed to mop the floor, the lifting component 300 drives the cleaning component 200 to move to the cleaning position (for example, a mopping position), and the cleaning member 221 contacts the ground. When the driving unit 210 drives the power transmission member 222 to drive the cleaning member 221 to vibrate, friction force is applied between the cleaning member 221 and the ground to mop and clean the ground.

[0241] In the embodiment of the present application, the cleaning assembly 200 is driven to switch between the lifting position and the cleaning position by the lifting assembly 300, so that when the cleaning member 221 is not mopping the floor, there is no need for the cleaning member 221 to always be in the mopping position. In this way, the cleaning member 221 can be released from contact with the ground, thereby reducing the friction loss between the cleaning member 221 and the ground and extending the service life of the cleaning member 221.

[0242] In some embodiments, the lifting assembly 300 includes a lifting motor 310, a rotating member 320 and a traction member, the output shaft of the lifting motor 310 is connected to the rotating member 320, one end of the traction member is connected to the rotating member 320 and is at least partially wound on the rotating member 320, and the other end of the traction member is connected to the cleaning assembly 200, so that when the output shaft of the lifting motor 310 rotates, the cleaning assembly 200 is driven to move along the first direction. In this way, the driving motor 211 drives the cleaning assembly 200 to rise and fall by traction through the traction member, and the implementation method is simple and the cost is low; in addition, the lifting assembly 300 drives the cleaning unit 220 and the driving unit 210 to rise and fall synchronously, so that the positions of the cleaning unit 220 and the driving unit 210 will not change relative to each other during lifting and falling, thereby improving the reliability of the relative position between the driving unit 210 and the cleaning unit 220.

[0243] It can be understood that by lifting and lowering the traction member by means of the lifting motor 310 , the consistency of the rising and falling distances of the cleaning assembly 200 can be ensured.

[0244] Exemplarily, the traction member includes a first traction member and a second traction member, one end of the first traction member and the second traction member are both wound on the rotating member 320, and the other ends of the first traction member and the second traction member are respectively connected to the opposite ends of the cleaning component 200. In this way, the first traction member and the second traction member are respectively connected to the opposite ends of the cleaning component 200, so that the stability of the cleaning component 200 during lifting and lowering can be improved.

[0245] Among them, the rotating member 320 is, for example, a winch or a rotating shaft, and the traction member is, for example, a traction rope; in addition, the first winding area and the second winding area are respectively provided on the rotating member 320. For example, the first traction member is wound in the first winding area, and the second traction member is wound in the second winding area. In this way, when the lifting motor 310 rotates forward or reverse, the first traction member and the second traction member can drive the cleaning component 200 to rise or fall. The structure and lifting method of the lifting component 300 are simple, easy to implement, and low in cost.

[0246] In some embodiments, the output shaft of the lifting motor 310 is connected to the rotating member 320, and the central axis of the output shaft of the lifting motor 310 is coaxially arranged with the central axis of the rotating member 320, so that the output shaft of the lifting motor 310 drives the rotating member 320 to rotate forward or reverse to wind up the traction member or release the traction member, thereby lifting or lowering the cleaning component 200.

[0247] In addition, the first winding area and the second winding area can be adjacent to each other along the axial direction of the rotating member 320. Exemplarily, the first winding area and the second winding area are respectively annular areas arranged on the outer wall surface of the rotating member 320 along the circumference of the rotating member 320. For example, at least one of the first winding area and the second winding area is an annular groove or an annular pit, etc., and there is no specific limitation.

[0248] In some embodiments, in order to improve the smoothness of the lifting and lowering of the cleaning component 200 driven by the traction member, a guide roller can be provided on the body 100, and the traction member between the rotating member 320 and the cleaning component 200 is movably provided on the guide roller to guide the traction member to avoid jamming between the traction member and the body 100, thereby improving the smoothness of the lifting and lowering of the traction member.

[0249] It should be noted that in the embodiment of the present application, the lifting assembly 300 drives the cleaning assembly 200 to lift and move as a whole. In this way, during the lifting process, the position between the driving unit 210 and the cleaning unit 220 will not change due to the lifting, thereby improving the reliability of the relative position between the driving unit 210 and the cleaning unit 220, and further improving the reliability of the driving unit 210 driving the power transmission component 222.

[0250] In addition, in order to improve the accuracy of the lifting route of the lifting assembly 300 driving the cleaning assembly 200 when lifting, please refer to Figure 8 As shown, in the embodiment of the present application, at least two first guide portions 227 are provided on the top plate 223, and a second guide portion 140 matching the first guide portion 227 is provided on the body 100. When the lifting assembly 300 drives the cleaning assembly 200 to move in the first direction, the first guide portion 227 moves along the second guide portion 140 to guide the movement of the cleaning assembly 200 in the first direction. In this way, when the lifting assembly 300 drives the cleaning assembly 200 to rise and fall, the mutual guidance between the first guide portion 227 and the second guide portion 140 is used to improve the accuracy of the route of the cleaning assembly 200 during lifting and falling.

[0251] Exemplarily, the first guide portion 227 is, for example, a first guide column, on which a guide hole is provided, for example, and the second guide portion 140 is a second guide column matching the guide hole; by setting the first guide portion 227 as an axial hole 2123 structure and setting the second guide portion 140 as a guide column matching the axial hole 2123 structure, the structure is simple, the cost is low, and it is easy to implement.

[0252] Of course, a guide hole matching the first guide column can also be provided on the second guide column. When the lifting component 300 drives the cleaning component 200 to lift or lower, the first guide column can be inserted into the guide hole and move relative to the guide hole to guide the lifting or lowering of the cleaning component 200. The guide structure is simple and easy to process and realize, thereby reducing costs.

[0253] In some embodiments, there may be at least two first guide portions 227, and at least two first guide portions 227 may be spaced apart on the top plate 223. Accordingly, the fuselage 100 may have a second guide portion 140 matching the first guide portions 227, so that the lifting and lowering of the cleaning component 200 can be guided by the multiple first guide portions 227 and the second guide portions 140 to ensure the stability of the cleaning component 200 during lifting and lowering.

[0254] Exemplarily, four first guide portions 227 are symmetrically arranged on the top plate 223, and correspondingly, four second guide portions 140 are arranged at positions on the body 100 corresponding to the first guide portions 227. When the lifting assembly 300 drives the cleaning assembly 200 to lift and lower, each first guide portion 227 and its corresponding second guide portion 140 guide the cleaning assembly 200 to improve the stability of the cleaning assembly 200 when it is lifted and lowered.

[0255] In some embodiments, the projection of the lifting assembly 300 in the first direction and the projection of the driving unit 210 in the first direction at least partially overlap, so that the compactness of the overall structure of the cleaning device 10 can be improved.

[0256] In addition, a accommodating space is provided on the side of the body 100 facing the cleaning component 200 and at a position corresponding to the driving unit 210. The driving unit 210 can be arranged in the accommodating space. In this way, the structural compactness of the cleaning device 10 can be further improved, the overall thickness of the cleaning device 10 can be reduced, the overall volume of the cleaning device 10 can be reduced, and the miniaturization of the cleaning device 10 can be achieved.

[0257] In some embodiments, the axis of the output shaft of the lifting motor 310 and the axis of the rotation center of the rotating member 320 are respectively parallel to the second direction; wherein the second direction is perpendicular to the first direction, for example, the second direction is a horizontal direction, that is, the output shaft of the lifting motor 310 and the rotation center of the rotating member 320 are coaxially arranged and horizontally arranged, so that the size of the body 100 in the first direction (for example, the thickness direction of the cleaning device 10) can be reduced, thereby reducing the thickness of the cleaning device 10 in the first direction, making the overall structure more compact.

[0258] In addition, in order to improve the intelligence level of the cleaning device 10, the driving unit 210 may also include a circuit board 214, and the circuit board 214 is electrically connected to the driving motor 211. The circuit board 214 can, for example, receive a control signal to control the start and stop, forward rotation or reverse rotation of the driving motor 211 according to the received control signal; of course, the circuit board 214 can also be electrically connected to the lifting motor 310, so that the circuit board 214 controls the lifting motor 310 to drive the cleaning component 200 to rise and fall according to the received lifting signal.

[0259] In some embodiments, please refer to Fig.13 As shown, the driving motor 211 is located above the top plate 223, the circuit board 214 is arranged between the top plate 223 and the driving motor 211, and a first vibration damper 700 is arranged between the circuit board 214 and the top plate 223. It can be understood that by arranging the first vibration damper 700 between the circuit board 214 and the top plate 223, the vibration of the driving motor 211 can be avoided from being transmitted to the top plate 223 through the circuit board 214, thereby reducing vibration noise.

[0260] In some embodiments, the first vibration damping member 700 can be a vibration damping pad, which is located between the top plate 223 and the circuit board 214 and wraps the outer periphery of the circuit board 214. For example, the top plate 223 and the circuit board 214 are completely isolated by the vibration damping pad. In this way, the vibration of the drive motor 211 can be further prevented from being transmitted to the top plate 223 through the circuit board 214, thereby further reducing vibration noise.

[0261] In some embodiments, please refer to Figures 14 to 16As shown, a second vibration damper 800 is provided between the second guide column and the fuselage 100, so as to prevent the vibration of the power transmission member 222 from being transmitted to the fuselage 100 through the second guide column by providing the second vibration damper 800 between the second guide column and the fuselage 100, thereby reducing vibration noise. Exemplarily, a second vibration damper 800 is provided at the position where the second guide column is connected to the fuselage 100, so as to absorb vibration through the second vibration damper 800 and reduce vibration noise.

[0262] In some embodiments, the second guide column is connected to the body 100 through a threaded connector 900 such as a screw. In the embodiments of the present application, screws are used as an example for description.

[0263] In order to prevent the second guide column from transmitting vibration to the fuselage 100 through threaded connectors 900 such as screws and causing vibration noise, a second vibration damper 800 can be provided between the second guide column and the fuselage 100 and between the screw and the fuselage 100, so as to isolate the direct contact between the second guide column and the fuselage 100 and isolate the direct contact between the screw and the fuselage 100 through the second vibration damper 800, thereby reducing the transmission of vibration and reducing vibration noise.

[0264] Exemplarily, the second guide column is provided with a threaded hole along the axial direction, and a through hole is provided on the body 100, a screw is passed through the through hole and is threadedly connected to the threaded hole, and the second vibration damper 800 is respectively provided between the hole wall of the through hole and the outer wall of the second guide column, and the second vibration damper 800 is provided between the body 100 and the nut of the screw, so that the second vibration damper 800 can absorb the vibration transmitted to the second guide column by the power transmission component 222, and absorb the vibration between the nut and the body 100, so as to avoid transmitting the vibration to the body 100, thereby reducing the vibration of the whole cleaning device 10 and reducing the vibration noise.

[0265] In some embodiments, the second vibration damping member 800 is a vibration damping ring, which is sleeved on the second guide column. By sleeved on the second guide column, the second guide column and the fuselage 100 can be isolated, thereby reducing the vibration of the entire machine and reducing vibration noise. The structure and installation method are simple, easy to implement, and low cost.

[0266] Exemplarily, both ends of the second vibration damper 800 also have extensions that wrap around the edges of both ends of the through hole of the fuselage 100, so that the second vibration damper 800 is formed into a vibration damping ring structure with a cross-section of, for example, an "I" shape. In this way, when the second vibration damper 800 is sleeved on the end of the second guide column close to the fuselage 100, the extensions at both ends of the second vibration damper 800 both wrap around the edge of the through hole of the fuselage 100, so that the extension at one end of the second vibration damper 800 is located between the fuselage 100 and the nut, and the extension at one end of the second vibration damper 800 wraps around the hole edge at the other end of the through hole, thereby completely isolating the fuselage 100 from the second guide column and from the fuselage 100 and the nut through the second vibration damper 800, thereby avoiding the transmission of vibration and reducing vibration noise.

[0267] In some embodiments, please refer to Fig.14 and Fig.15 As shown, the second vibration damper 800 can wrap the outer wall surface of the second guide column from bottom to top, so as to reduce the vibration transmission between the second guide column and the fuselage 100 to a greater extent.

[0268] Exemplarily, the second vibration damping member 800 includes a first vibration damping ring 820 and a second vibration damping ring 830 connected in sequence, the first vibration damping ring 820 and the second vibration damping ring 830 are coaxially arranged, and the projection area of ​​the first vibration damping ring 820 in the first direction is larger than the projection area of ​​the second vibration damping ring 830, and the second vibration damping ring 830 wraps the entire outer wall surface of the second guide column. For example, the second vibration damping member 800 includes a through hole passing through the first vibration damping ring 820 and the second vibration damping ring 830 in sequence, the second guide column is penetrated in the through hole, and the first vibration damping ring 820 is located between the nut and the fuselage 100, and the second vibration damping ring 830 is located between the fuselage 100 and the second guide column, so as to reduce the transmission of vibration and reduce vibration noise.

[0269] In addition, an end of the second vibration damping ring 830 away from the first vibration damping ring 820 may be provided with an avoidance gap for avoiding the first guide column, so that the second guide column is plugged into the guide hole on the first guide column, and the avoidance gap is used to avoid the first guide column.

[0270] In order to further improve the vibration reduction effect, in the embodiment of the present application, please refer to Fig.16 As shown, a plurality of vibration-damping ribs 810 may also be provided on the outer wall surface of the second vibration-damping ring 830. The plurality of vibration-damping ribs 810 are arranged at intervals along the circumference of the second vibration-damping ring 830. Since the compression deformation effect of a single vibration-damping rib 810 is better than the compression deformation effect of the entire surface, the vibration-damping ribs 810 on the outer wall surface of the second vibration-damping ring 830 can further improve the vibration damping effect, reduce the transmission of vibration, and reduce vibration noise.

[0271] In other embodiments, please refer to Fig.17As shown, at least two vibration-damping ribs 810 are arranged on the end surface of the second vibration-damping member 800 on the side close to the fuselage 100, and the at least two vibration-damping ribs 810 are arranged at intervals in the circumferential direction of the second vibration-damping member 800. In this way, when the screw connects the second guide column and the fuselage 100, the nut of the screw directly contacts the vibration-damping rib 810 to reduce the contact area between the nut and the second vibration-damping member 800. Since the compression deformation space of a single vibration-damping rib 810 is better than the compression deformation effect of the entire surface contact, it can better achieve the vibration reduction effect.

[0272] Exemplarily, at least two vibration-damping ribs 810 may form an axial array on the end surface of the second vibration-damping member 800 close to the fuselage 100 with the central axis of the second vibration-damping member 800 to achieve a vibration-damping effect and reduce vibration noise.

[0273] The first vibration damper 700 and the second vibration damper 800 may be made of a material with elastic vibration absorption, for example, the first vibration damper 700 and the second vibration damper 800 may be made of rubber or silicone, etc., as long as the transmission of vibration can be reduced, and there is no limitation here.

[0274] In the embodiment of the present application, two-level vibration reduction is formed between the cleaning unit 220 and the body 100 by the first vibration reduction member 700 and the second vibration reduction member 800. In this way, the transmission of vibration can be reduced, and the vibration of the entire cleaning device 10 can be reduced, thereby reducing vibration noise and improving the user experience.

[0275] A second aspect of an embodiment of the present application provides a cleaning system, including: a base station and the cleaning device provided in the above embodiment.

[0276] Among them, the base station and the cleaning device are used in combination. For example, when the cleaning device is not working, it can return to the base station; or when the cleaning device needs to refill the clean water tank in the body, charge the battery, or clean the garbage in the dust box in the body, it needs to return to the base station for refilling, charging, or cleaning garbage.
