Description

TECHNICAL FIELD

[0002] The existing mop machine is divided into a handheld mop machine and a mop robot. The mop cloth is arranged on the handheld mop machine and the mop robot to mop the ground. The handheld mop machine is mainly manually pushed to move to clean the ground. The user needs to manually push the mop machine, which is inconvenient to use. The handheld mop machine cannot move on the ground autonomously, which is inconvenient for the user to use and consumes time and effort.

[0003] The mop robot can move on the ground, but it moves by arranging driving wheels. The driving wheels rotate to drive the mop robot to move. The driving wheels need to be arranged with multiple motors to realize rotation driving, and a transmission structure also needs to be arranged, which leads to a complex overall structure and high cost. Although the driving wheels realize stable movement, the driving wheels occupy a large part of the bottom space of the mop robot. Because the position of the driving wheels needs to be limited on the center axis of the mop robot, it is not easy to arrange the mop cloth on the bottom of the mop robot. The mop cloth cannot cover a large area when avoiding the driving wheels. The overall structure is complex and the cost is high.

[0004] The mop cloth on the existing handheld mop machine or mop robot is generally arranged with two mop cloths. However, there is a gap between the two mop cloths. At present, some mop cloths are arranged in a special shape to solve the problem of missing cleaning. However, the special structure of the mop cloth leads to difficult installation and high cost.

[0005] At the same time, the mop cloth on the existing handheld mop machine and mop robot needs to be manually disassembled for cleaning. Especially when the mop cloth is seriously dirty, the user manually disassembles the mop cloth for cleaning, which leads to a poor experience and is very inconvenient. SUMMARY

[0006] The present application aims to at least solve one of the above technical problems in the related art to some extent.

[0061] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0062] Embodiment: The cleaning machine of the present application, as shown in the drawings, is mainly used for cleaning the working surface, which can be the ground surface, such as ceramic tile ground surface, wooden floor ground surface, or glass surface, all of which can be cleaned by the cleaning machine 1 of the present application. Figures 1 to 20 As shown in the drawings, the cleaning machine 1 is mainly used for cleaning the working surface, which can be the ground surface, such as ceramic tile ground surface, wooden floor ground surface, or glass surface, all of which can be cleaned by the cleaning machine 1 of the present application.

[0063] The existing floor cleaning robot is provided with a driving wheel, and the driving wheel is used for walking of the floor cleaning robot to clean the indoor floor. Although a good walking track and a planned path can be obtained, a gear box is arranged in the driving wheel, a plurality of groups of transmission gears are arranged in the gear box, and the driving wheel is driven to rotate for walking through the gears. However, the gears are easily damaged, and lubricating oil is needed to maintain the lubricating effect, which is inconvenient to maintain. In addition, the cost of the driving wheel is high, and the structure is complex. At the same time, the driving wheel occupies part of the position of the floor cleaning robot, so that the mop cannot be easily installed at the bottom of the floor cleaning robot. At the same time, there are many technical problems and use problems in the installation of the mop, such as the inability to clean the wall edge and the corner of the wall.

[0064] The purpose of the present scheme is to provide a cleaning machine 1 which can realize large-area adhesion to the ground and large friction to clean the ground. A mop rotating assembly 101 which can rotate horizontally is arranged on the cleaning machine 1 to realize the cleaning effect, and the cleaning machine 1 is automatically displaced and walks through the mop rotating assembly 101. The driving wheel on the existing floor cleaning robot is abolished, and the overall structure is simple and the cost is lower.

[0065] The cleaning machine 1 comprises a machine body 100, a cleaning assembly for cleaning a working surface is arranged on the machine body 100, and the cleaning assembly at least comprises a mop rotating assembly 101 which is arranged in a structure capable of horizontally rotating and adhering to the working surface. The mop rotating assembly 101 is used for cleaning by horizontally rotating and adhering to the working surface. The number of the mop rotating assembly 101 can be one or more. A pressing assembly 102 is arranged on the machine body 100. When the cleaning machine 1 is located on the working surface and the mop rotating assembly 101 horizontally rotates and adheres to the working surface, at least a part of the pressing assembly 102 contacts the mop rotating assembly 101, so that the bottom surface of the mop rotating assembly 101 has an unbalanced pressure relative to the working surface, and the cleaning machine 1 is displaced. The pressing assembly 102 contacts the mop rotating assembly 101 to form an unbalanced pressure of the bottom surface of the mop rotating assembly 101 relative to the working surface when the bottom surface of the mop rotating assembly 101 adheres to the working surface. The unbalanced pressure can make the cleaning machine 1 walk and displace on the working surface.

[0066] At least a part of the pressing assembly 102 presses a part of the mop rotating assembly 101 to form an unbalanced pressure of the bottom surface of the mop rotating assembly 101 relative to the working surface, so that the cleaning machine 1 can displace under the unbalanced pressure instead of remaining at the original position without displacement. The mop rotating assembly 101 has the functions of cleaning the floor and driving the rotation and walking.

[0067] Specifically, the structure part of the crimping assembly 102 for applying pressure to the crimping of the rotating and dragging assembly 101 is provided, the crimping assembly 102 contacts the rotating and dragging assembly 101 and forms a crimping area 1013 on the rotating and dragging assembly 101, and at least part of the area of the rotating and dragging assembly 101 contacting the working surface outside the crimping area 1013 is a cleaning area 1014. At least part of the crimping area 1013 and part of the cleaning area 1014 contact the working surface, so that the rotating and dragging assembly 101 adheres to the working surface to form at least two areas on the bottom surface of the rotating and dragging assembly 101, one of which is the crimping area 1013 and the other is the cleaning area 1014. The cleaning area 1014 and the crimping area 1013 form an uneven pressure of the bottom surface of the rotating and dragging assembly 101 relative to the working surface, thereby realizing the automatic displacement of the cleaning machine 1.

[0068] Among them, the cleaning area 1014 and the crimping area 1013 are mainly formed on the bottom surface of the rotating and dragging assembly 101, so that the bottom surface of the rotating and dragging assembly 101 forms the two areas.

[0069] The scheme sets the crimping assembly 102 to apply pressure to the rotating and dragging assembly 101 through the crimping assembly 102, so that an uneven pressure is formed between the bottom surface of the rotating and dragging assembly 101 and the working surface, thereby realizing the automatic walking of the rotating and dragging assembly 101 under the condition of uneven force, and automatically displacing along the force direction. Walking, which cancels the need to set a driving wheel for walking of the existing robot, has a simple structure, low cost, and high reliability.

[0070] In detail, when the crimping assembly 102 contacts the rotating and dragging assembly 101, the maximum pressure in the crimping area 1013 relative to the working surface is greater than the minimum pressure in the cleaning area 1014 relative to the working surface. The pressure is the ratio of the pressure and the force area. In the case of the cleaning area 1014 and the crimping area 1013 in the scheme, it is only necessary to ensure that the maximum pressure existing in the crimping area 1013 is greater than the minimum pressure in the cleaning area 1014 to ensure that the bottom surface of the rotating and dragging assembly 101 has an uneven pressure relative to the working surface. The area of the cleaning area 1014 on the rotating and dragging assembly 101 is greater than the area of the crimping area 1013. The cleaning area 1014 is mainly used for large-area contact with the working surface for cleaning, and the crimping area 1013 has greater pressure relative to the cleaning area 1014 while cleaning the working surface. This makes the crimping area 1013 also have the effect of realizing the autonomous displacement of the cleaning machine 1.

[0071] Optionally, the pressure in the entire area of the cleaning area 1014 can be uneven, the pressure of the entire area of the pressing area 1013 received by the pressing assembly 102 can be uneven, but it is ensured that the maximum pressure of at least a part of the area in the entire area of the pressing area 1013 relative to the working surface is greater than the minimum pressure of at least a part of the area in the entire area of the cleaning area 1014 relative to the working surface, that is, the rotating and dragging assembly 101 has uneven pressure to realize that the rotating and dragging assembly 101 can drive the cleaning machine 1 to automatically displace and walk.

[0072] Optionally, the average pressure of the entire area of the pressing area 1013 can be greater than the average pressure of the entire area of the cleaning area 1014, and at this time, the pressing area 1013 and the cleaning area 1014 can form the bottom surface of the rotating and dragging assembly 101 to have an uneven pressure effect.

[0073] In detail, when the rotating and dragging assembly 101 is horizontally rotated to fit the working surface, the maximum unit area friction between the pressing area 1013 and the working surface is greater than the minimum unit area friction between the cleaning area 1014 and the working surface, so that the cleaning machine 1 is displaced on the working surface, the pressing assembly 102 applies pressure to the rotating and dragging assembly 101, and the rotating and dragging assembly 101 also receives the gravity of the cleaning machine 1 itself, so that the rotating and dragging assembly 101 generates friction with the working surface when it is horizontally rotated to fit the working surface. The bottom surface of the rotating and dragging assembly 101 of the present scheme fits the working surface, and the maximum unit area friction between the pressing area 1013 and the working surface is greater than the minimum unit area friction between the cleaning area 1014 and the working surface, so that there is uneven friction between at least a part of the cleaning area 1014 and at least a part of the pressing area 1013. Through the uneven friction, the rotating and dragging assembly 101 can displace and walk during horizontal rotation due to the uneven effect of the friction, and further realize the displacement of the cleaning machine 1 by the rotating and dragging assembly 101.

[0074] The cleaning assembly in the scheme includes at least two rotary mop assemblies 101. When the cleaning assembly includes two rotary mop assemblies 101, the two rotary mop assemblies 101 are arranged in a parallel distribution structure, and the horizontal rotation directions of the two rotary mop assemblies 101 are at least opposite. By arranging two rotary mop assemblies 101 in a parallel distribution on the machine body 100 and arranging the horizontal rotation directions of the two rotary mop assemblies 101 to be opposite, the two rotary mop assemblies 101 can be arranged in a left-right parallel distribution. The rotation directions of the two rotary mop assemblies 101 are preferably arranged to rotate from the front side of the machine body 100 to the rear side and arranged to rotate from the outer side of the machine body 100 to the inner side. The left rotary mop assembly 101 and the right rotary mop assembly 101 are both horizontally rotated toward the middle position between the two rotary mop assemblies 101, as shown in Figure 3 This is more conducive to the displacement movement of the cleaning machine 1 under the horizontal rotation of the two rotary mop assemblies 101.

[0075] Preferably, the cleaning assembly includes two rotary mop assemblies 101 arranged on the machine body 100, which is more conducive to the displacement movement of the cleaning machine 1 along the planned path.

[0076] One way to apply pressure to the structure part of the rotary mop assembly 101 by the crimping assembly 102 is that the crimping assembly 102 is located between the two rotary mop assemblies 101, and at least a part of the crimping assembly 102 contacts the two rotary mop assemblies 101 respectively and forms the crimping area 1013 on the two rotary mop assemblies 101 respectively. That is, the crimping assembly 102 is located between the two rotary mop assemblies 101, and can be located at the position with the smallest distance between the two rotary mop assemblies 101. It is only necessary to satisfy that at least a part of the crimping assembly 102 can contact the two rotary mop assemblies 101 respectively to perform crimping and form the crimping area 1013 on the two rotary mop assemblies 101 respectively. At this time, the crimping assembly 102 can not only form the crimping area 1013 by applying pressure to satisfy that the two rotary mop assemblies 101 can realize the displacement movement of the cleaning machine 1, but also realize that there is no mop gap between the two rotary mop assemblies 101, which is conducive to solving the problem of the gap caused by the minimum distance between the two rotary mops. The cleaning machine 1 can maintain a complete single cleaning effect during the cleaning of the working surface. If there is no crimping assembly 102, the minimum distance between the two rotary mop assemblies 101 cannot effectively adhere to the working surface, resulting in a mop gap. At the same time, the crimping assembly 102 can be arranged to apply pressure to the two rotary mop assemblies 101, the overall structure is relatively simple, and the consistency and synchronization of the crimping pressure are better.

[0077] Meanwhile, the pressing assembly 102 can be arranged between the two rotating mop assemblies 101, and two pressing assemblies 102 can be arranged to contact the two rotating mop assemblies 101 respectively and form the pressing areas 1013 on the two rotating mop assemblies 101 respectively. Two pressing assemblies 102 can be arranged to independently press the two rotating mop assemblies 101 respectively. For example, a left pressing assembly 102 is arranged on the left rotating mop assembly 101, and a right pressing assembly 102 is arranged on the right rotating mop assembly 101. In this way, the pressing areas 1013 can be formed on the two rotating mop assemblies 101 respectively, and the cleaning machine 1 can move and walk automatically under the horizontal rotation of the two rotating mop assemblies 101. The two pressing assemblies 102 are arranged between the two rotating mop assemblies 101, and the distance between the two rotating mop assemblies 101 is the smallest. In this way, the two pressing assemblies 102 can not only form the independent pressing areas 1013 on the two rotating mop assemblies 101 to meet the movement and walking of the cleaning machine 1, but also can realize that there is no missing area between the two rotating mop assemblies 101, which is beneficial to solve the problem of the smallest distance between the two rotating mop assemblies 101.

[0078] In another way of the structure of the pressing assembly 102 pressing the rotating mop assembly 101, two independent pressing assemblies 102 are arranged on the two rotating mop assemblies 101 respectively, and a part of the at least two pressing assemblies 102 contacts the two rotating mop assemblies 101 respectively and forms the pressing areas 1013 on the two rotating mop assemblies 101 respectively. In other words, two independent pressing assemblies 102 are arranged on the two independent rotating mop assemblies 101 respectively. One of the pressing assemblies 102 independently presses one of the rotating mop assemblies 101, and the other pressing assembly 102 independently presses the other rotating mop assembly 101. The two independent pressing assemblies 102 form independent pressing areas 1013 on the two rotating mop assemblies 101 respectively. The two independent pressing areas 1013 can realize independent and uniform or non-uniform pressure on the two rotating mop assemblies 101 respectively, and the cleaning machine 1 can move and walk under the non-uniform pressure on the two rotating mop assemblies 101.

[0079] Preferably, the two rotating mop assemblies 101 are arranged in parallel, and the two pressing assemblies 102 are arranged symmetrically in the horizontal direction or the vertical direction. In this way, the cleaning machine 1 can maintain stability and consistency during movement and walking, and can move and walk in a straight line, such as forward movement or backward movement.

[0080] Specifically, in this scheme, the linear displacement walking direction of the cleaning machine 1 can be set as the A direction, and the pressing area 1013 is located at an angle B between the plane perpendicular to the bottom surface of the rotating and dragging assembly 101 in the A direction, and B is greater than 0 degrees. That is, the A direction can be the forward direction of the linear displacement walking of the cleaning machine 1 or the backward direction of the linear displacement walking of the cleaning machine 1, and the pressing assembly 102 applies pressure to the rotating and dragging assembly 101 and makes the pressing area 1013 on the rotating and dragging assembly 101 form an angle B between the plane perpendicular to the bottom surface of the rotating and dragging assembly 101 in the A direction. That is, the pressing area 1013 is not located on the plane perpendicular to the bottom surface of the rotating and dragging assembly 101 in the A direction. At this time, the pressure or friction formed by the pressing area 1013 can form an angle between the plane perpendicular to the bottom surface of the rotating and dragging assembly 101 in the A direction, so that the cleaning machine 1 can perform linear displacement walking under the action of the pressure or friction without being in a stationary position. At this time, the corresponding two pressing areas 1013 on the two rotating and dragging assemblies 101 can form an angle B between the two planes perpendicular to the bottom surfaces of the two rotating and dragging assemblies 101 in the A direction. At this time, the cleaning machine 1 can maintain linear displacement walking in the A direction with the two rotating and dragging assemblies 101.

[0081] For the structure part of the rotating and dragging assembly 101, the rotating and dragging assembly 101 can be movably mounted on the machine body 100 in the vertical direction and in a floating structure. The rotating and dragging assembly 101 can be displaced up and down on the relatively adhered working surface by a certain distance, which is beneficial to improve the displacement walking of the rotating and dragging assembly 101 across obstacles and improve the applicability range of the rotating and dragging assembly 101, and is beneficial to the displacement walking of the cleaning machine 1.

[0082] And / or, the rotating and dragging assembly 101 is movably mounted on the machine body 100 in the horizontal direction and in a circumferential swinging structure. The rotating and dragging assembly 101 is mainly sleeved on the machine body 100, and an axial shaft gap is arranged in the sleeved structure to realize the circumferential movement of the rotating and dragging assembly 101 within the shaft circumference of the sleeved shaft part, so that the pressing assembly 102 can make the rotating and dragging assembly 101 swing or tilt within a certain range when pressing the rotating and dragging assembly 101, so as to better adhere to the working surface, and at the same time, it is more beneficial for the pressing assembly 102 to make the rotating and dragging assembly 101 better adapt to adhere to the working surface when applying pressure to the rotating and dragging assembly 101.

[0083] Specifically, the present scheme makes the rotary-drag assembly 101 in an inclined structure in the vertical direction and / or the horizontal direction when a part of the pressure assembly 102 contacts the rotary-drag assembly 101; that is, when the pressure assembly 102 exerts pressure on the rotary-drag assembly 101, it can make the rotary-drag assembly 101 move in the vertical direction to adapt to the working surface and make the rotary-drag assembly 101 move in the horizontal direction to adapt to the working surface, so as to better form the pressure contact area 1013 and the cleaning area 1014 on the bottom surface of the rotary-drag assembly 101, and at the same time, the rotary-drag assembly 101 can cross obstacles to better adapt to the working surface.

[0084] Specifically, when the pressure assembly 102 contacts the pressure contact rotary-drag assembly 101, the rotary-drag assembly 101 can be in an inclined structure relative to the working surface under the action to adapt to the working surface, so as to better form the pressure contact area 1013 and the cleaning area 1014 on the bottom surface of the rotary-drag assembly 101, and better adapt to the working surface to perform horizontal rotation and drive the cleaning machine 1 to automatically displace and walk.

[0085] Optionally, or at least a part of the rotary-drag assembly 101 is provided in a deformable structure, when a part of the pressure assembly 102 contacts the rotary-drag assembly 101, at least part of the rotary-drag assembly 101 is in a deformed structure, that is, when the pressure assembly 102 pressure contacts the rotary-drag assembly 101, because at least part of the rotary-drag assembly 101 is in a deformed structure, under the action of the pressure of the pressure contact, the part is deformed to adapt to the working surface and form the pressure contact area 1013, so that the pressure assembly 102 more easily forms the pressure contact area 1013 on the rotary-drag assembly 101, and has less effect on the horizontal rotation of the rotary-drag assembly 101; for example, when a soft structure mop is arranged on the rotary-drag assembly 101, the pressure assembly 102 can directly pressure contact on the mop to perform pressure contact to form the pressure contact area 1013 on the mop, which is more convenient for the pressure assembly 102 to contact and pressure contact.

[0086] For the structure provided with two rotating and dragging assemblies 101, the pressure of one of the pressing assemblies 102 on the pressing area 1013 of one of the rotating and dragging assemblies 101 is set as F1, and the pressure of the other pressing assembly 102 on the pressing area 1013 of the other rotating and dragging assembly 101 is set as F2. One way can be understood as follows: when the two rotating and dragging assemblies 101 are arranged side by side, the left rotating and dragging assembly 101 and the right rotating and dragging assembly 101 are provided, and the left pressing assembly 102 and the right pressing assembly 102 are correspondingly provided. The pressure of the right pressing assembly 102 on the right rotating and dragging assembly 101 is F1, and the pressure of the left pressing assembly 102 on the left rotating and dragging assembly 101 is F2. When the cleaning machine 1 moves in the direction of one of the rotating and dragging assemblies 101, F1 is greater than F2. The one rotating and dragging assembly 101 can be understood as the right rotating and dragging assembly 101. When the cleaning machine 1 moves in the direction of the other rotating and dragging assembly 101, F2 is greater than F1. The other rotating and dragging assembly 101 can be understood as the left rotating and dragging assembly 101. By adjusting the size of F1 and F2, the steering displacement walking of the cleaning machine 1 can be realized, such as left turning walking or right turning walking. That is, when the cleaning machine 1 turns right, F1 is greater than F2, and when the cleaning machine 1 turns left, F2 is greater than F1, as shown in Figure 12 , 13 When the rotating and dragging assembly 101 slips or abnormally causes the straight line to bend or deviate to be inclined, the cleaning machine 1 can be corrected to return to the straight line walking direction. A direction sensor or an angle sensor can be installed in the machine body 100 to realize the sensing of the walking direction of the cleaning machine 1. At this time, the pressing assembly can be set to be movable to press the rotating and dragging assembly 101, so as to adjust the pressing height or depth of the pressing assembly 102, and further realize the adjustment of the pressure.

[0087] For the structure provided with two rotating and dragging assemblies 101, when the cleaning machine 1 moves in the straight line in the A direction, at least F1 value is set to be equal to F2 value, as shown in Figure 11 At this time, it is beneficial for the cleaning machine 1 to keep straight line displacement. The pressing areas 1013 of the two rotating and dragging assemblies 101 can be set to be symmetrical structures in the horizontal direction or the vertical direction, which is more beneficial for the cleaning machine 1 to keep stability and consistency during displacement walking, and is beneficial for the cleaning machine 1 to move in a straight line, which can be displacement walking in a straight line forward or backward.

[0088] In the scheme, when the cleaning machine 1 moves in a straight line along the A direction, the resultant forces of the two rotating and dragging assemblies 101 relative to the working surface do not cancel each other out, that is, the resultant forces of the cleaning areas 1014 and the pressing areas 1013 of the rotating and dragging assemblies 101 relative to the bottom surface of the entire rotating and dragging assembly 101 relative to the working surface do not cancel each other out, that is, they are not equal and opposite. At this time, the cleaning machine 1 can move and walk in a straight line under the action of the resultant forces of the two rotating and dragging assemblies 101 relative to the working surface. The resultant forces of the two rotating and dragging assemblies 101 relative to the working surface can respectively push the cleaning machine 1 to walk in the A direction along the A direction, which is beneficial to maintaining straight-line displacement walking.

[0089] When the cleaning machine 1 moves in a rotating direction, such as left turn walking or right turn walking, that is, when the cleaning machine 1 moves in a rotating direction, the resultant moments of the two rotating and dragging assemblies 101 relative to the working surface do not cancel each other out, so that the two rotating and dragging assemblies 101 have their own moments, that is, rotating forces or angular forces, under the action of their own resultant moments relative to the working surface. At this time, the cleaning machine 1 can turn and move under the joint action of the resultant moments of the two rotating and dragging assemblies 101, that is, the cleaning machine 1 can realize left turn walking or right turn walking.

[0090] Alternatively, the turning walking of the cleaning machine 1 can be realized by setting the pressure values of the corresponding pressing assemblies 102 of the two rotating and dragging assemblies 101 and forming the resultant moment values of the two rotating and dragging assemblies 101 relative to the working surface. When the cleaning machine 1 moves in the direction of one of the rotating and dragging assemblies 101, the resultant moment of the one rotating and dragging assembly 101 is greater than that of the other rotating and dragging assembly 101. When the cleaning machine 1 moves in the direction of the other rotating and dragging assembly 101, the resultant moment of the other rotating and dragging assembly 101 is greater than that of the one rotating and dragging assembly 101, thereby realizing the turning displacement walking of the cleaning machine 1. Specifically, the pressure of the pressing assembly 102 on the pressing area 1013 can be adjusted. It can be understood that one of the rotating and dragging assemblies 101 is a left rotating and dragging assembly 101, and the other rotating and dragging assembly 101 is a right rotating and dragging assembly 101.

[0091] In this scheme, when the cleaning machine 1 moves in a straight line along direction A, the resultant force of the pressing area 1013 on one of the rotary dragging components 101 is equal in magnitude and symmetrical in direction along direction A with the resultant force of the pressing area 1013 on the other rotary dragging component 101. That is, the resultant force of the pressing area 1013 on one rotary dragging component 101 relative to the working surface is equal in magnitude and symmetrical in direction along direction A with the resultant force of the pressing area 1013 on the other rotary dragging component 101 relative to the working surface. This allows the cleaning machine 1 to move in a straight line under the combined action of the resultant forces of the pressing areas 1013 on the two rotary dragging components 101, and it is also beneficial to maintain the cleaning machine 1 moving in a straight line. Direction A can be the forward direction or the backward direction of the cleaning machine 1 moving in a straight line. Under the combined action of the two forces, the cleaning machine 1 can move forward or backward in a straight line stably.

[0092] When the cleaning machine 1 turns, that is, when the cleaning machine 1 turns, the turn can be a left turn or a right turn. It can also be achieved in the following way: when the cleaning machine 1 moves and turns in the direction of one of the rotary mopping components 101, the rotation direction of the other rotary mopping component 101 is switched to be the same as the rotation direction of the first rotary mopping component 101 and set to rotate in the direction of the first rotary mopping component 101. At this time, by setting the horizontal rotation direction of the two rotary mopping components 101 to the same direction, the force of the horizontal rotation of the two rotary mopping components 101 is concentrated in one direction, thereby achieving the turning of the cleaning machine 1. Specifically, the rotation direction of the two rotary mopping components 101 is a horizontal rotation in the direction in which the cleaning machine 1 needs to turn. Specifically, one rotary mopping component 101 can be understood as the left rotary mopping component 101, and the other rotary mopping component 101 as the right rotary mopping component 101. When the cleaning machine 1 needs to turn to the left, such as... Figure 15 As shown, the horizontal rotation direction of the right-side rotary mopping component 101 is switched to be consistent with the horizontal rotation direction of the left-side rotary mopping component 101. The horizontal rotation directions of both the left and right rotary mopping components 101 are set to rotate towards the left-side rotary mopping component 101, i.e., towards the left side of the cleaning machine 1. Furthermore, it is set to rotate horizontally from the front to the rear of the cleaning machine 1. This allows for better turning of the cleaning machine 1. Similarly, it can achieve right turns. When the cleaning machine 1 needs to turn to the right, such as... Figure 14As shown, the horizontal rotation direction of the left side rotating and dragging assembly 101 is switched to be consistent with the horizontal rotation direction of the right side rotating and dragging assembly 101, and the horizontal rotation directions of the left side rotating and dragging assembly 101 and the right side rotating and dragging assembly 101 are rotated towards the right side rotating and dragging assembly 101, that is, towards the right side of the cleaning machine 1, and are horizontally rotated from the front side to the rear side of the cleaning machine 1, so that the turning of the cleaning machine 1 can be better realized.

[0093] When the cleaning machine 1 turns, that is, when the cleaning machine 1 turns, the turning can be left turning or right turning, and can also be in the following manner: mainly by being arranged that when the cleaning machine 1 is displaced towards the direction of one of the rotating and dragging assemblies 101, the one rotating and dragging assembly 101 stops rotating and the other rotating and dragging assembly 101 is arranged to rotate towards the direction of the one rotating and dragging assembly 101, at this time, by arranging to stop the horizontal rotation of the one rotating and dragging assembly 101, the other rotating and dragging assembly 101 generates a rotating force during horizontal rotation to realize the turning of the cleaning machine 1 as a whole; specifically, it can be understood that one of the rotating and dragging assemblies 101 is the left side rotating and dragging assembly 101, and the other rotating and dragging assembly 101 is the right side rotating and dragging assembly 101, when the cleaning machine 1 needs to turn to the left side, as shown in Figure 17 at this time, the left side rotating and dragging assembly 101 stops horizontal rotation, the right side rotating and dragging assembly 101 is in a horizontal rotation state, the horizontal rotation direction of the right side rotating and dragging assembly 101 is rotated towards the left side of the cleaning machine 1 and is horizontally rotated from the front side to the rear side of the cleaning machine 1, so that at least under the action of the rotating force of the rotating and dragging assembly 101, the cleaning machine 1 is driven to turn, that is, left turning; similarly, when the cleaning machine 1 needs to turn to the right side, as shown in Figure 16 at this time, the right side rotating and dragging assembly 101 stops horizontal rotation, the left side rotating and dragging assembly 101 is in a horizontal rotation state, and the horizontal rotation direction of the left side rotating and dragging assembly 101 is rotated towards the right side of the cleaning machine 1 and is horizontally rotated from the front side to the rear side of the cleaning machine 1, so that at least under the action of the rotating force of the rotating and dragging assembly 101, the cleaning machine 1 is driven to turn, that is, left turning; at this time, the turning of the cleaning machine 1 can be better realized.

[0094] In the scheme, the power of the horizontal rotation structure of the rotating and dragging assembly 101 is arranged to have a driving mechanism, the driving mechanism mainly includes a motor, the motor drives the horizontal rotation of the rotating and dragging assembly 101, the motor shaft can be connected to the rotating and dragging assembly 101 through a support to rotate the horizontal rotation structure of the rotating and dragging assembly 101, or the motor shaft can be connected to a gear to drive the horizontal rotation structure of the rotating and dragging assembly 101 through the gear; the rotating speed of the rotating and dragging assembly 101 can be correspondingly configured according to the rotating speed of the motor, and the horizontal rotation direction of the rotating and dragging assembly 101 can be adjusted by forward and reverse rotation of the motor.

[0095] Among them, the control module is arranged on the cleaning machine 1 in the scheme, and the control module is electrically connected with the rotary drag assembly 101. The control module mainly controls the opening, stopping and horizontal rotation direction (such as forward rotation or reverse rotation) of the rotary drag assembly 101, which can be realized by setting control program in the control module. When two rotary drag assemblies 101 are arranged, the control module can control the independent opening, stopping and horizontal rotation direction of the two rotary drag assemblies 101. Of course, one motor can be arranged to drive the two rotary drag assemblies 101 to work synchronously, and the control module can control the motor to realize synchronous control of the two rotary drag assemblies 101.

[0096] In the above scheme of the present scheme, when the two rotary drag assemblies 101 are respectively provided with the crimping assembly 102, the two crimping assemblies 102 are arranged as independent split structures or as an integral structure. That is, one rotary drag assembly 101 is provided with an independent crimping assembly 102, and the other rotary drag assembly 101 is provided with an independent crimping assembly 102. The two independent split crimping assemblies 102 are respectively arranged on the two rotary drag assemblies 101 to realize the corresponding functions. That is, the crimping assembly 102 arranged on one rotary drag assembly 101 and the crimping assembly 102 arranged on the other rotary drag assembly 101 are arranged as an integral structure, which is convenient for installation or disassembly, convenient for later maintenance, and also conducive to maintaining the stability of the pressure of the crimping assembly 102 on the two rotary drag assemblies 101 and maintaining the synchronization of the pressure.

[0097] The structure of the crimping assembly 102 in the present scheme mainly includes a crimping piece 1021, which at least partially extends downward to contact the rotary drag assembly 101. The part of the crimping piece 1021 extending downward to contact the rotary drag assembly 101 forms the effect of applying pressure to the rotary drag assembly 101, so that the bottom surface of the rotary drag assembly 101 has different pressures in the area contacting the working surface, and different friction forces are generated during horizontal rotation, so that the automatic displacement walking effect of the cleaning machine 1 is realized by the rotary drag assembly 101.

[0098] The specific structure part of the crimping assembly 102 can also be that the crimping piece 1021 extends downward to crimp contact the rotary mop assembly 101, and the crimping piece 1021 is arranged in a movable structure, and the elastic piece 1023 is connected to the crimping piece 1021; the crimping piece 1021 is arranged in a movable structure, and can adjust the position height along with the fluctuation of the rotary mop assembly 101 under the condition that the pressure applied to the rotary mop assembly 101, i.e. the pressure applied to the crimping area 1013, is maintained, and when the rotary mop assembly 101 rotates horizontally on an uneven working surface, the rotary mop assembly 101 can be affected by the working surface and appear uneven, at this time, the elastic piece 1023 can play a buffering effect of force.

[0099] In order to realize that the pressure applied to the rotary mop assembly 101 by the crimping assembly 102 can be adjusted, i.e. the pressure applied to the crimping area 1013 can be adjusted, the crimping assembly 102 further comprises an adjusting piece 1022, which is used to adjust the downward extension distance of the crimping piece 1021; the adjusting piece 1022 can be provided with a motor, and the motor is used to drive the upward and downward movement of the adjusting piece 1022 by a certain distance, and the rotating force of the motor can be transmitted to the upward and downward movement force of the adjusting piece 1022; when it is needed to increase the pressure of the crimping assembly 102 on the rotary mop assembly 101, i.e. the pressure of the crimping area 1013 on the rotary mop assembly 101, the downward extension distance of the crimping piece 1021 to contact the rotary mop assembly 101 can be adjusted by the adjusting piece 1022 at this time, so that the crimping distance of the crimping piece 1021 on the rotary mop assembly 101 is large, i.e. the crimping is tighter, and at this time, the pressure of the crimping area 1013 on the rotary mop assembly 101 is larger, at this time, the friction force of the rotary mop assembly 101 on the working surface can be controlled by adjusting the pressure, and then the direction of the cleaning machine 1 can be adjusted by the rotary mop assembly 101, such as left turning or right turning of the cleaning machine 1, and the two crimping assemblies 102 on the two rotary mop assemblies 101 can be adjusted to have different pressures on the crimping areas 1013 of the two rotary mop assemblies 101, so as to realize the adjustment of the turning direction of the cleaning machine 1 by the two rotary mop assemblies 101, and the overall structure is simple, and the problem of adjusting the turning direction by different rotating speeds of the existing driving wheels is replaced.

[0100] In the scheme, the specific structure of the spin mop assembly 101 is that the spin mop assembly 101 comprises a spin mop disc 1011, the lower side of the spin mop disc 1011 is provided with a spin mop cloth 1012, the spin mop assembly 101 is in a columnar structure as a whole, the spin mop cloth 1012 is installed on the spin mop disc 1011 to realize the rotation of the spin mop cloth 1012 driven by the spin mop disc 1011 and the close compression of the spin mop cloth 1012 to form a bottom surface contact working surface of the spin mop cloth 1012 for cleaning, the compression assembly 102 contacts the spin mop disc 1011 or the spin mop cloth 1012 to form a compression structure; the compression assembly 102 can realize the compression of the spin mop assembly 101 by contacting and compressing the spin mop disc 1011 or the spin mop cloth 1012, and finally realize that the bottom surface of the spin mop assembly 101 is the bottom surface of the spin mop cloth 1012, which has an unbalanced pressure between the bottom surface and the working surface and an unbalanced friction force, and the spin mop cloth 1012 will displace and walk in the process of horizontal rotation instead of keeping the original position; a rotating shaft part can be arranged on the spin mop disc 1011, and a rotating shaft part driving mechanism is connected to realize the rotation of the spin mop assembly 101, that is, to realize the rotation of the spin mop cloth 1012 driven by the spin mop disc 1011, and the rotation mode is horizontal rotation.

[0101] In the scheme, the compression assembly 102 contacts and compresses the compression area 1013 and the cleaning area 1014 formed by the spin mop assembly 101 to form a compression area on the bottom surface of the spin mop assembly 101, that is, on the bottom surface of the spin mop cloth 1012, so that the bottom surface of the spin mop cloth 1012 has an unbalanced pressure.

[0102] When the compression assembly 102 directly compresses the spin mop disc 1011, a compression groove can be arranged on the spin mop disc 1011, and a part of the compression part is inserted into the compression groove, so that the part of the compression part is always located in the compression groove during the horizontal rotation of the spin mop disc 1011 to compress the spin mop disc 1011 and the spin mop cloth 1012;

[0103] Optionally, the compression part is provided with an arc-shaped sliding point, the sliding point is located in the compression groove to realize the compression effect, which is conducive to reducing the resistance of the sliding point to the spin mop disc 1011 while maintaining the pressure of the sliding point to the spin mop disc 1011 and the spin mop cloth 1012, and preventing the sliding point from affecting the horizontal rotation of the spin mop disc 1011.

[0104] The structure of the spin mop cloth 1012 is that the spin mop cloth 1012 is provided in a soft structure, the spin mop cloth 1012 can be made of cloth material or composed of a plurality of fine plastic wool strips, so that the spin mop cloth 1012 can rotate horizontally on the ground to clean the ground with a large friction force.

[0105] The structure of the rotary mop 1012 can also be set to a soft structure, and at least includes a first soft part 10121 and a second soft part 10122, and the first soft part 10121 and the second soft part 10122 have different hardness or density. The rotary mop 1012 can be made of cloth or plastic bristles, but by setting the first soft part 10121 and the second soft part 10122, the rotary mop 1012 can achieve different cleaning effects when rotating horizontally on the ground. When the first soft part 10121 and the second soft part 10122 have different hardness or density, the part with higher hardness or density can form a strong cleaning effect on the ground, which is beneficial to remove large particles of garbage and dirt adhering to the ground. The part with lower hardness or density can be more soft to the ground to clean the ground in detail, which is beneficial to adsorb small dust or dirt. The rotary mop 1012 of the present scheme can achieve better cleaning effect.

[0106] At the same time, because the first soft part 10121 and the second soft part 10122 have different hardness or density, the friction force of the two parts on the working surface will be different, which is beneficial to clean the floor and also beneficial to realize the autonomous walking of the cleaning machine 1 through the rotary mop assembly 101. The corresponding position limit and combination position limit of the first soft part 10121, the second soft part 10122, the pressure contact area 1013 and the cleaning area 1014 can be set as needed.

[0107] Optionally, the first soft part 10121 can be made of cloth, and the second soft part 10122 can be made of plastic bristles, so that the hardness of the first soft part 10121 is less than the hardness of the second soft part 10122. The first soft part 10121 can be attached to the ground to absorb dust, and the second soft part 10122 can be attached to the ground to strongly scrape and remove dirt or scrape and remove large garbage particles adhering to the ground. The cleaning effect of the rotary mop assembly 101 is better.

[0108] The cleaning machine 1 of the scheme also has a multifunctional use effect. Specifically, a docking portion 1001 is arranged on the machine body 100. The docking portion 1001 is used for docking and mounting a handle rod 1002. When the handle rod 1002 is docked and mounted on the docking portion 1001, the cleaning machine 1 can be driven by the handle rod 1002 to clean the working surface. Specifically, the docking portion 1001 is used for docking and mounting the handle rod 1002. When the handle rod 1002 is docked and mounted on the docking portion 1001, the cleaning machine 1 can be driven by the handle rod 1002 to clean the working surface, that is, a handheld floor mopping machine is formed, which is convenient for users to use. When the user does not want to participate in manual mopping, the handle rod 1002 is dismounted at this time. At this time, the cleaning machine 1 can be used to clean the components to realize automatic displacement and walking movement on the working surface by using the autonomous movement of the cleaning machine 1 to clean the working surface. When the user needs to manually participate in mopping, the handle rod 1002 is mounted on the docking portion 1001 at this time. The user can hold the handle rod 1002 to mop and clean the ground. Therefore, the cleaning machine 1 of the scheme has a multifunctional use effect.

[0109] Optionally, the docking portion 1001 is arranged in a sleeve type structure. The handle rod 1002 can be sleeved and mounted into the docking portion 1001 to be limited and mounted and docked, which is convenient for users to use.

[0110] For the cleaning machine 1 of the scheme, a corresponding cleaning seat 2 is arranged to realize cleaning of the rotary mopping assembly 101. The cleaning of the rotary mopping assembly 101 is realized by using the horizontal rotation power of the rotary mopping assembly 101 itself.

[0111] Specifically, the cleaning machine 1 also includes the cleaning seat 2. The cleaning seat 2 is arranged as an independent part relative to the cleaning machine 1. The cleaning machine 1 can be independently placed on the cleaning seat 2 or independently taken away from the cleaning seat 2. The user can participate in placing or taking away according to the cleaning requirement of the rotary mopping assembly 101. The cleaning seat 2 is provided with a cleaning area 200. The cleaning area 200 is provided with a cleaning piece 201. The rotary mopping assembly 101 is placed in the cleaning area 200 and contacts with the cleaning piece 201 to form a scraping structure. In the case of cleaning liquid on the rotary mopping assembly 101, the cleaning piece 201 can realize scraping and cleaning of the rotary mopping assembly 101. After cleaning, the rotary mopping assembly 101 can be scraped and spun to remove water.

[0112] Specifically, the cleaning assembly is arranged to be at least partially embedded in the cleaning area 200 and at least partially contact the cleaning member 201 to form a scraping structure when the cleaning machine 1 is placed on the cleaning seat 2. The cleaning assembly, i.e., the spin mop assembly 101, is embedded in the cleaning area 200 to perform horizontal rotation cleaning. The spin mop assembly 101 is provided with horizontal rotation force, and in the process of horizontal rotation, the spin mop assembly 101 contacts the cleaning member 201 to scrape and remove dirt and garbage. At this time, the spin mop assembly 101 can be supplied with cleaning liquid or directly immersed in the cleaning liquid to achieve the cleaning effect of the spin mop assembly 101.

[0113] Optionally, the cleaning member 201 is arranged to be capable of contacting the spin mop assembly 101. The cleaning member 201 can be arranged in a protruding structure, such as a protruding sheet or strip structure, or a protruding column structure. The cleaning member 201 only needs to satisfy the condition that the cleaning member 201 can contact the spin mop assembly 101 and form a scraping structure for the spin mop assembly 101 when the spin mop assembly 101 rotates.
