Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a surface cleaning device and a cleaning system. Background Art

[0002] The window-cleaning robot mainly relies on the vacuum pump or fan device at the bottom of itself to firmly adhere to the glass, and then with the help of a certain level of artificial intelligence, it automatically detects the distance to the corners of the window, plans the window-cleaning path, and returns to its original position after cleaning to make it easier for users to remove it.

[0003] In the related art, a window-cleaning robot includes a robot body and an anti-collision plate arranged around the outer periphery of the robot body. Boundary detectors are also arranged at the corners of the window-cleaning robot. The boundary detector at least partially protrudes beyond the outer contour of the anti-collision plate and is fixedly connected to the anti-collision plate. A collision sensing component is arranged between the anti-collision plate and the robot body. In this way, when the boundary detector collides with the glass frame, the boundary detector will send a certain displacement, so that the anti-collision plate triggers the collision sensing component to detect that the window-cleaning robot has reached the frame position of the glass.

[0004] However, as the moving speed of the window cleaning robot increases, when the window cleaning robot collides with the glass frame, the glass frame has a greater impact on the anti-collision plate, and the anti-collision plate is prone to severe deformation and damage.

[0111] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme 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 part of the embodiments of the present application, rather than 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 are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0112] An embodiment of the present application provides a surface cleaning device, which includes but is not limited to a window cleaning robot for cleaning glass surfaces such as windows. The surface cleaning device will be introduced below using a window cleaning robot as an example.

[0113] Please refer to Figures 1 to 3 As shown, the surface cleaning device 100 includes a device body 110 and an adsorption component 300 disposed on the device body 110, and the adsorption component 300 is used to make the device body 110 adsorb on the surface of the glass, wherein the adsorption component 300 includes but is not limited to a vacuum pump or a negative pressure fan device, etc.

[0114] The surface cleaning device 100 further includes a base plate 112, a walking assembly 200 and a rag, wherein the rag is disposed at the bottom end of the base plate 112 (e.g., the side facing the glass surface), and the edge of the rag coincides with the edge of the base plate 112. Along the walking direction of the surface cleaning device 100, the walking assembly 200 can be disposed at the front and rear sides or the left and right sides of the base plate 112, so that the surface cleaning device 100 can walk on the glass surface through the walking assembly 200 to clean the glass surface through the rag. Exemplarily, the walking assembly 200 includes but is not limited to a crawler structure.

[0115] Please continue to refer to Figures 1 to 3 As shown, the surface cleaning device 100 also includes an anti-collision member 120. Exemplarily, the anti-collision member 120 is an anti-collision plate, which is arranged on the outer peripheral side of the device body 110, especially on the outer peripheral side of the bottom plate 112, that is, the anti-collision plate is annular in structure and is movably connected to the device body 110, so that the anti-collision member 120 can move relative to the device body 110 in a direction perpendicular to the side wall of the bottom plate device body 110. In this way, when the surface cleaning device 100 encounters an obstacle, the anti-collision member 120 will retract to one side of the device body 110, so that the anti-collision member 120 can protect the device body 110.

[0116] In addition, the surface cleaning device 100 also includes a collision sensing member 150, which is, for example, a collision sensor. The collision sensor is arranged between the anti-collision member 120 and the device body 110, and on one of the anti-collision member 120 and the device body 110. In this way, when the anti-collision member 120 encounters an obstacle, the anti-collision member 120 retracts to one side of the device body 110, and the collision sensor can be triggered to send a collision signal to the controller of the surface cleaning device 100. The controller determines that the surface cleaning device 100 has been collided based on the collision signal, and controls the surface cleaning device 100 to stop or turn.

[0117] It can be seen that if the glass has a frame, the collision sensor can be used to detect whether the surface cleaning device 100 reaches the frame of the glass; or, the collision sensor is used to detect whether the surface cleaning device 100 collides with an obstacle.

[0118] In some embodiments, please refer to Figures 1 to 5 As shown, the surface cleaning device 100 also includes a corner component 130, which is arranged at a corner position of the surface cleaning device 100. For example, the surface cleaning device 100 is a rectangular structure, and the area where two adjacent sides of the rectangle intersect and are adjacent is a corner position; at least a portion of the corner component 130 protrudes from the outer contour of the base plate 112.

[0119] Please refer to Figures 6 to 10 As shown, the corner assembly 130 includes a fixing member 131 and a boundary detection member 134, wherein the fixing member 131 is connected to the anti-collision member 120, wherein the fixing member 131 has a receiving space with an opening at the bottom, and the boundary detection member 134 is located in the receiving space and can extend out of the receiving space through the opening at the bottom or be accommodated inside the receiving space.

[0120] In addition, the corner assembly 130 also includes an elastic member 133, which includes but is not limited to a spring, and the boundary detection member 134 can be a boundary detection ball; the elastic member 133 is arranged between the top of the boundary detection member 134 and the top wall of the accommodating space, so that the boundary detection member 134 is movably arranged on the fixing member 131 through the elastic member 133, and the boundary detection member 134 can protrude from the bottom end of the bottom plate 112 under the action of the elastic member 133 and abut against the glass surface.

[0121] In some embodiments, the corner assembly 130 also includes a rotating member 132, which includes but is not limited to a roller. The roller is rotatably disposed on the fixed member 131, and at least a portion of the roller protrudes beyond the outer contour of the anti-collision member 120. When the surface cleaning device 100 moves along the edge of the glass, the roller is used to roll in contact with the glass frame to reduce friction with the glass frame.

[0122] In addition, the boundary detection member 134 is located on at least one side of the roller, or the boundary detection member 134 is located in the roller, for example, Figures 2 to 5 In the figure, the boundary detection member 134 is arranged in the roller, and under the elastic force of the elastic member 133, it protrudes from the bottom end of the roller and abuts against the glass surface, that is, the roller is arranged around the outer peripheral side of the boundary detection member 134, and the boundary detection member 134 can move up and down along the axial direction of the roller relative to the roller.

[0123] When the glass is frameless glass, if the surface cleaning device 100 moves to the point where the boundary detection member 134 is outside the glass, the boundary detection member 134 moves downward under the elastic force of the elastic member 133 to protrude from the bottom plate 112. At this time, the elastic member 133 is in a freely extended state, and the boundary detection member 134 is released from contact with the surface of the glass and is triggered, and sends a signal to the controller of the surface cleaning device 100. The controller determines the position change of the surface cleaning device 100 based on the signal to prevent the risk of the surface cleaning device 100 falling from the edge.

[0124] When the glass is framed glass, the boundary detection member 134 is always in contact with the glass surface. When the surface cleaning device 100 encounters an obstacle (such as a glass frame), the roller collides with the glass frame first. Under the action of the collision impact force, the roller drives the anti-collision member 120 to retract to the side of the device body 110, and the anti-collision member 120 triggers the collision sensor. The collision sensor is triggered and sends a collision signal to the controller of the surface cleaning device 100. The controller determines that the surface cleaning device 100 has been collided based on the collision signal to determine that the surface cleaning device 100 has reached the glass frame.

[0125] In order to reduce the friction between the boundary detection member 134 and the glass surface, the boundary detection member 134 is a boundary detection ball, which can rotate around its own axis. In this way, when the boundary detection ball abuts against the glass surface, the boundary detection ball can also rotate around its own axis, thereby reducing the friction between the boundary detection ball and the glass surface.

[0126] In order to improve the accuracy of the vertical movement path of the boundary detection member 134 in the accommodation space, in the embodiment of the present application, please refer to Figure 8 and Fig. 9As shown, the corner assembly 130 also includes a clamping member 135 and a guide member 136. The clamping member 135 is arranged on the top of the boundary detection member 134 and is used to clamp the boundary detection member 134, and the boundary detection member 134 can rotate around its own axis relative to the clamping member 135. The guide member 136 is arranged on the top of the boundary detection member 134 and is connected to the clamping member 135. The guide member 136 passes through the top wall of the accommodating space and is movably connected to the fixing member 131, so that the guide member 136 can drive the boundary detection member 134 to move up and down in the accommodating space relative to the fixing member 131, wherein the guide member One end of 136 close to the boundary detection member 134 has a limiting portion, and the elastic member 133 is located between the limiting portion and the top wall of the accommodating space, so that the elastic member 133 can drive the boundary detection member 134 to move toward the side away from the fixing member 131 through its own elastic force, so that at least part of the boundary detection member 134 extends out of the bottom end of the bottom plate 112 of the surface cleaning device 100; the boundary detection member 134 can also push the guide member 136 to move toward the side close to the fixing member 131 under the action of external force, so that at least part of the structure of the boundary detection member 134 can be retracted into the accommodating space.

[0127] Exemplarily, the guide member 136 may be connected to the fixing member 131 via a limit screw 137 , and the guide member 136 may move up and down relative to the fixing member 131 in a direction perpendicular to the glass surface via the limit screw 137 .

[0128] In addition, a trigger switch may be provided on the side wall of the boundary detection member 134. When the boundary detection member 134 moves beyond the outer contour of the frameless glass, the boundary detection member 134 moves downward under the elastic force of the elastic member 133, and the trigger switch of the boundary detection member 134 is triggered, so that the boundary detection member 134 sends a signal to the controller of the surface cleaning device 100, thereby determining that the surface cleaning device 100 moves to a position close to the edge of the glass, and the elastic member 133 is in a freely extended state at this time; when the boundary detection member 134 moves onto the glass surface with the surface cleaning device 100, the boundary detection member 134 moves upward under the push of the glass, and the boundary detection member 134 abuts against the surface of the glass, and at this time, the elastic member 133 is in a compressed state, and the trigger portion on the boundary detection member 134 is de-triggered.

[0129] In order to improve the cleaning efficiency of the surface cleaning device 100, the traveling speed of the surface cleaning device 100 is constantly increasing. However, as the traveling speed of the surface cleaning device 100 increases, when the portion of the corner assembly 130 protruding from the anti-collision component 120 collides with the frame of the glass, there is a problem of large impact force. The corner assembly 130 and the anti-collision component 120 are relatively fixed, which causes the anti-collision component 120 to be easily damaged by impact, especially the position of the anti-collision component 120 close to the corner assembly 130, which has the problem of serious deformation and damage. In addition, the anti-collision component 120 is large in size, and it is difficult to replace the anti-collision component 120 after it is damaged and the replacement cost is high.

[0130] In view of the above problems, in the embodiments of this application, please refer to Figure 4 and Figure 5 As shown, the corner component 130 is movably arranged on the anti-collision member, and at least a portion of the corner component 130 protrudes from the outer contour of the bottom plate 112, that is, at least a portion of the structure of the corner component 130 forms the outermost contour of the surface cleaning device 100; when the corner component 130 is not impacted, at least a portion of the corner component 130 protrudes from the outer edge of the anti-collision member 120; when the corner component 130 is impacted, the corner component 130 moves relative to the anti-collision member 120, and after the corner component 130 moves to contact the anti-collision member 120, it drives the anti-collision member 120 to move relative to the device body 110.

[0131] It should be noted that the state in which the corner assembly 130 is impacted refers to the state in which the corner assembly 130 starts to move relative to the anti-collision component 120 .

[0132] It can be seen that in the embodiment of the present application, the corner component 130 is movably arranged on the anti-collision component 120, so that when the corner component 130 is hit, it first moves a certain distance and then drives the anti-collision component 120 to move. Compared with the corner component 130 being fixedly connected to the anti-collision component 120 and directly driving the anti-collision component 120 to move under the impact force, the present application can buffer the impact force of the collision to reduce the impact force on the anti-collision component 120 and avoid the problem of the anti-collision component 120 being deformed or even damaged by collision.

[0133] In addition, the corner assembly 130 can be detachably connected to the anti-collision member 120, so that the corner assembly 130 can be replaced when it is damaged by an impact. Since the corner assembly 130 is smaller in size than the anti-collision member 120, it is simple and easy to replace the corner assembly 130.

[0134] In some embodiments, please refer to Figure 4 and Figure 5As shown, the anti-collision component 120 includes a first anti-collision portion 121 and a second anti-collision portion 122 connected to each other, the first anti-collision portion 121 and the second anti-collision portion 122 intersect and are adjacent to each other, a corner area 123 is formed between the first anti-collision portion 121 and the second anti-collision portion 122, and a corner component 130 is movably arranged in the corner area 123; when the corner component 130 is not impacted, at least part of the corner component 130 protrudes outward from the outer edge of the first anti-collision portion 121 and the outer edge of the second anti-collision portion 122; when the corner component 130 is impacted, the corner component 130 moves in the corner area 123; when the corner component 130 contacts the first anti-collision portion 121, the first anti-collision portion 121 is driven to move and then the second anti-collision portion 122 is driven to move; or, when the corner component 130 contacts the second anti-collision portion 122, the second anti-collision portion 122 is driven to move and then the first anti-collision portion 121 is driven to move.

[0135] It should be noted that the anti-collision member 120 includes multiple anti-collision parts. For the convenience of description, one of any two intersecting and adjacent anti-collision parts is represented by a first anti-collision part, and the other of any two intersecting and adjacent anti-collision parts is represented by a second anti-collision part, wherein "first, second..." is only for the convenience of description and has no other special meaning.

[0136] In addition, there is a notch at the bottom of each corner of the anti-collision member 120, that is, the corner of the anti-collision member 120 refers to the area where the first anti-collision portion 121 and the second anti-collision portion 122 intersect and are adjacent, and the notch is formed as a corner area 123. It can be understood that the notch is used to avoid the corner component 130, so that the corner component 130 is movably arranged at the corner area 123, so that the corner component 130 can move in the corner area 123 when the corner component is hit.

[0137] Please refer to Figure 4 and Figure 5 As shown, the end of the first anti-collision part 121 facing the notch (i.e., the corner area 123) has a first pushing part 1211, and the end of the second anti-collision part 122 facing the notch has a second pushing part 1221, and the first pushing part 1211 and the second pushing part 1221 are connected; in this way, when the corner component 130 is hit, the corner component 130 moves in the corner area, and when the corner component 130 contacts the first pushing part 1211, it drives the first anti-collision part 121 to move and then drives the second anti-collision part 122 to move; or, when the corner component 130 contacts the second pushing part 1221, it drives the second anti-collision part 122 to move and then drives the first anti-collision part 121 to move.

[0138] That is to say, when the corner component 130 moves in the corner area 123, the first anti-collision part 121 can be pushed by the first pushing part 1211 to move, so that the first anti-collision part 121 drives the second anti-collision part 122 to move; or, the corner component 130 can be pushed by the second anti-collision part 1221 to move, so that the second anti-collision part 122 drives the second anti-collision part 121 to move.

[0139] Since the first push portion 1211 is located at the end of the first anti-collision portion 121 in the length direction, and the second push portion 1221 is located at the end of the second anti-collision portion 122 in the length direction, when the corner assembly 130 is collided with the first push portion 1211 or the second push portion 1221, the deformation of the first anti-collision portion 121 or the second anti-collision portion 122 can be reduced.

[0140] In some embodiments, please refer to Figure 4 As shown, a first collision sensing member 151 is disposed on one side of the first collision prevention portion 121 close to each corner assembly 130, and a second collision sensing member is disposed on one side of the second collision prevention portion 122 close to each corner assembly 130; for example, Figure 4 In the embodiment, collision sensors are provided on both sides of the corners of each corner assembly 130, so that when any position of the surface cleaning device 100 collides with the glass frame, it can be detected by the collision sensor, thereby improving the accuracy of collision detection.

[0141] In some embodiments, please refer to Figure 4 As shown, the ratio of the minimum distance between the first collision sensing component 151 and the corner assembly 130 (represented by D1) to the length of the first anti-collision part 121 (represented by H1) is 1 / 7 to 1 / 5; preferably, the ratio of the minimum distance between the first collision sensing component 151 and the corner assembly 130 to the length of the first anti-collision part 121 is 1 / 6; the ratio of the minimum distance between the second collision sensing component and the corner assembly to the length of the second anti-collision part is 1 / 7 to 1 / 5; preferably, the ratio of the minimum distance between the second collision sensing component and the corner assembly to the length of the second anti-collision part is 1 / 6.

[0142] Exemplarily, when the length of the anti-collision member 120 is 270 mm, the distance between the collision sensor arranged on the anti-collision member 120 and the corresponding corner component 130 is about 45 mm. In this way, the problem of the collision sensor being too close to the corner component 130 and easily being triggered by mistake can be avoided, and the problem of the collision sensor being too far from the corner component 130 and resulting in poor sensitivity can also be avoided. This improves the detection sensitivity of the collision sensor and solves the problem of the collision sensor being easily triggered by mistake, thereby improving the user experience.

[0143] Please continue to refer to Figure 5As shown, the surface cleaning device 100 further includes a first restoring member 141 and a second restoring member 142. The first restoring member 141 is disposed between the corner assembly 130 and the first anti-collision portion 121. When the corner assembly 130 is impacted along the length direction of the first anti-collision portion 121, the first restoring member 141 is in a compressed state. When the impact of the corner assembly 130 in the length direction of the first anti-collision portion 121 is released, the first restoring member 141 is used to drive the corner assembly 130 to reset in the opposite direction, that is, to drive the corner assembly 130 to reset in the opposite direction. Moves to the side away from the first anti-collision part 121; the second reset member 142 is arranged between the corner assembly 130 and the second anti-collision part 122. When the corner assembly 130 is hit along the length direction of the second anti-collision part 122, the second reset member 142 is in a compressed state. When the collision of the corner assembly 130 in the length direction of the second anti-collision part 122 is released, the second reset member 142 is used to drive the corner assembly 130 to reset in the opposite direction, that is, to drive the corner assembly 130 to move to the side away from the second anti-collision part 122.

[0144] Exemplarily, the first reset member 141 and the second reset member 142 include but are not limited to springs, elastic columns, elastic pads, elastic foams, etc. As long as they can reset the corner assembly 130 by their own elastic force, no limitation is made here.

[0145] In addition, when the first reset member 141 and the second reset member 142 are elastic structures such as springs, when a collision occurs between the corner assembly 130 and the glass frame, the reset member 140 can absorb at least part of the impact force to achieve the purpose of buffering, thereby reducing the impact force transmitted to the anti-collision member 120, thereby avoiding the problem of deformation and damage of the anti-collision member 120.

[0146] In some embodiments, please refer to Figure 5 As shown, the corner assembly 130 is rotatably connected to the anti-collision member 120. For example, the anti-collision member 120 defines a rotation axis, and the fixing member 131 is rotatably connected to the anti-collision member 120. When the corner assembly 130 is subjected to an external force, the corner assembly 130 can rotate around the rotation axis relative to the anti-collision member 120, so that when the corner assembly 130 is subjected to a collision impact force, it first moves a certain distance around the rotation axis relative to the anti-collision member 120, and then drives the anti-collision member 120 to move.

[0147] In other embodiments, the corner assembly 130 is slidably connected to the anti-collision member 120. When the corner assembly 130 is subjected to an external force, the corner assembly 130 can slide relative to the anti-collision member 120 within a preset distance. In this way, the corner assembly 130 moves a first distance under the action of the collision impact force and then drives the anti-collision member 120 to move, so as to reduce the impact force on the anti-collision member 120.

[0148] Exemplarily, one of the corner component 130 and the anti-collision member 120 has a slide rail, and the other has a slide groove matching the slide rail, and the slide rail is configured to slide along the extension direction of the slide groove; for example, the fixing member 131 in the corner component 130 is provided with a slide rail, and the anti-collision member 120 has a slide groove matching the slide rail along the movement direction of the corner component 130, so that when the corner component 130 is subjected to the impact force of a collision, the corner component 130 slides along the slide groove relative to the anti-collision member 120 to improve the accuracy and smoothness of the movement route of the corner component 130.

[0149] In addition, when the corner assembly 130 drives the anti-collision component 120 to retract toward the side of the device body 110 under the action of the impact force of the collision, part of the structure of the corner assembly 130 always protrudes from the edge of the anti-collision component 120 on the side away from the device body 110, that is, regardless of whether the corner assembly 130 collides with the glass frame, part of the structure of the corner assembly 130 always protrudes from the outer contour of the anti-collision component 120, so as to avoid contact between the anti-collision component 120 and the glass frame, thereby further enhancing the protection of the anti-collision component 120.

[0150] In order to make the corner component 130 protrude beyond the outer contour of the anti-collision part 120 in any state, in the embodiment of the present application, the distance that the corner component 130 protrudes from the outer edge of the anti-collision part 120 in the length direction of the first anti-collision part 121 is greater than the maximum distance that the corner component 130 moves in the length direction of the first anti-collision part 121 in the corner area 123; the distance that the corner component 130 protrudes from the outer edge of the anti-collision part 120 in the length direction of the second anti-collision part 122 is greater than the maximum distance that the corner component 130 moves in the length direction of the second anti-collision part 122 in the corner area 123.

[0151] In this way, when the corner assembly 130 drives the anti-collision component 120 to retract toward the side of the device body 110, part of the structure of the corner assembly 130 always protrudes beyond the outer contour of the anti-collision component 120, so that there is a gap between the anti-collision component 120 and the glass frame under any circumstances, so as to avoid direct contact between the anti-collision component 120 and the glass frame, and reduce the wear and deformation of the anti-collision component 120 due to collision.

[0152] In addition, the anti-collision component 120 may be made of a material with certain strength and toughness to enhance the impact resistance and strength of the anti-collision component 120 .

[0153] In the surface cleaning device 100 provided in the embodiment of the present application, the rag is arranged at the bottom end of the bottom plate 112 in the device body 110. When the surface cleaning device 100 moves on the glass surface, the rag can clean the glass surface. However, when the glass is framed glass, the frame of the glass cannot be cleaned, thereby affecting the user's experience.

[0154] In response to the above-mentioned problems, the surface cleaning device 100 provided in the embodiment of the present application further includes a frame cleaning piece, and at least part of the structure of the frame cleaning piece protrudes outward from the contour of the side of the anti-collision piece 120 away from the device body 110, so that the frame cleaning piece forms the outermost surface of the surface cleaning device 100. In this way, when the surface cleaning device 100 moves along the glass frame, the frame cleaning piece is used to clean the glass frame.

[0155] Exemplarily, the cleaning surface of the frame cleaning piece faces the glass frame, and the portion of the frame cleaning piece that protrudes beyond the outer contour of the anti-collision piece 120 faces the glass frame, thereby improving cleaning efficiency.

[0156] In some embodiments, the frame cleaning member is disposed on the outer contour surface of the anti-collision member 120 , so that when the surface cleaning device 100 moves along the glass frame, the frame cleaning member can clean the glass frame.

[0157] In other embodiments, the frame cleaning member can be set on the rotating member 132 (i.e., the rolling surface) in the corner assembly 130. In this way, the frame cleaning member forms the outermost contour of the corner assembly 130. When the rotating member rolls along the glass frame, it drives the frame cleaning member to rotate synchronously, so that the frame cleaning member can reduce the friction between the frame cleaning member and the glass frame while cleaning the glass frame, thereby extending the life of the frame cleaning member and reducing costs.

[0158] Exemplarily, the frame cleaning member includes but is not limited to a hair-implanted member, that is, the hair-implanted member is formed as the outermost contour of the corner component, wherein the hair-implanted member can be formed on the outer surface of the rotating member by spraying, gluing, etc.

[0159] In order to reduce the friction between the fixed part and the rotating part and the smoothness of the roller rotation, in some embodiments, a bearing is arranged between the fixed part and the rotating part to realize the rotation of the rotating part; however, the rotating part realizes relative rotation with the fixed part through the bearing, which has the problems of cumbersome and complicated disassembly and assembly and high cost.

[0160] Based on the above problems, please refer to the embodiments of this application. Figures 6 to 10As shown, a first rotational matching portion 1311 is provided on the fixed member 131, and a second rotational matching portion 1321 matching the first rotational matching portion 1311 is provided on the rotating member 132. The second rotational matching portion 1321 is rotationally matched with the second rotational matching portion 1321, so that the rotating member 132 can rotate around its own axis relative to the fixed member 131 under the action of force, and the hardness of the first rotational matching portion 1311 and the second rotational matching portion 1321 are different. In this way, the rotating member 132 can rotate relative to the fixed member 131. At the same time, the friction between the first rotating fitting part 1311 and the second rotating fitting part 1321 can be reduced; illustratively, the first rotating fitting part 1311 can be one of the rotating shaft and the rotating hole, and the second rotating fitting part 1321 can be the other of the rotating shaft and the rotating hole. Compared with the rotating part 132 being rotatably connected to the fixed part 131 through a bearing, the embodiment of the present application realizes the self-rotation of the rotating part 132 through the first rotating fitting part 1311 and the second rotating fitting part 1321. At the same time, the disassembly and assembly are simple and the cost is low.

[0161] In some embodiments, please refer to Figure 8 and Fig. 9 As shown, the first rotating matching portion 1311 is a rotating shaft, and the second rotating matching portion 1321 is a rotating hole, that is, the rotating member 132 is sleeved on the fixed member 131 and can rotate relative to the fixed member 131, wherein the hardness of the rotating shaft is less than the hardness of the hole wall of the rotating hole, thereby reducing the friction between the rotating shaft and the rotating hole.

[0162] In addition, the rotating member 132 is rotatably arranged on the fixed member 131 and is detachably connected to the fixed member 131 to avoid the problem of the rotating member 132 falling off from the fixed member 131; it can be understood that after the rotating member 132 is detachably connected to the fixed member 131, the rotating member 132 can rotate around its own axis relative to the fixed member 131, that is, the detachable connection between the rotating member 132 and the fixed member 131 does not affect the self-rotation of the rotating member 132.

[0163] In some embodiments, please refer to Figures 8 to 10 As shown, the fixed member 131 has a first clamping portion 1312, and the rotating member 132 has a second clamping portion 1322 matching the first clamping portion 1312. The first clamping portion 1312 is configured to be clamped with the first clamping portion 1312, and when the rotating member 132 rotates relative to the fixed member 131 under the action of a force, the second clamping portion 1322 is configured to move relative to the first clamping portion 1312. In other words, the rotating member 132 is detachably connected to the fixed member 131 by clamping, which is simple to disassemble and assemble, has a simple structure, and is low in cost. After clamping, it does not affect the self-rotation of the rotating member 132.

[0164] Exemplarily, the first clamping portion 1312 can be one of the clamping protrusions and the clamping grooves extending along the rotation direction of the rotating member 132, and the second clamping portion 1322 can be the other of the clamping protrusions and the clamping grooves extending along the rotation direction of the rotating member 132, so that when the rotating member 132 rotates relative to the fixed member 131, the clamping protrusion moves along the extension direction of the clamping groove.

[0165] In some embodiments, the outer wall surface of the rotating shaft has one of a clamping protrusion and a clamping groove extending along the circumference of the rotating shaft, and the hole wall of the rotating hole has the other of a clamping protrusion and a clamping groove extending along the circumference of the rotating hole; when the rotating shaft is installed in the rotating hole, the clamping protrusion is located in the clamping groove, thereby improving the structural compactness of the corner assembly 130, and the structure is simple, easy to implement, and low cost.

[0166] For example, in Figures 8 to 10 In the figure, the first rotating matching part 1311 is a rotating shaft, and a clamping groove extending along the circumference of the rotating shaft is provided on the outer wall surface of the rotating shaft, and the second rotating matching part 1321 is a rotating hole, and a clamping protrusion extending along the circumference of the rotating hole is provided on the hole wall of the rotating hole. Since the rotating shaft is passed through the rotating hole and the clamping protrusion is located in the clamping groove, in order to avoid interference between the rotating shaft and the clamping protrusion when the rotating shaft is passed through the rotating hole, after the rotating shaft is passed through the rotating hole, there is a large gap between the outer wall surface of the rotating shaft and the hole wall of the rotating hole, which causes radial shaking when the rotating member 132 rotates around the fixed member 131, thereby affecting the stability of the rotating member 132 during its rotation.

[0167] Based on the above problems, in an embodiment of the present application, at least one of the first rotating matching portion 1311 and the second rotating matching portion 1321 has at least two contact portions 1323 arranged at intervals along its circumference. When the first rotating matching portion 1311 and the second rotating matching portion 1321 cooperate with each other, the contact portion 1323 is configured to make sliding contact with the other of the first rotating matching portion 1311 and the second rotating matching portion 1321, so as to reduce the radial gap between the first rotating matching portion 1311 and the second rotating matching portion 1321 through the contact portion 1323, thereby improving the problem of shaking of the rotating member 132 when rotating relative to the fixed member 131, and further improving the stability of the rotating member 132 when rotating.

[0168] For example, please refer to Fig. 9 and Fig.10As shown, the second rotating fitting portion 1321 (rotating hole) has at least two contact portions 1323, and the at least two contact portions 1323 are arranged at intervals along the circumference of the second rotating fitting portion 1321, wherein the contact portion 1323 can be a contact protrusion, so as to reduce the gap between the first rotating fitting portion 1311 and the second rotating fitting portion 1321 through the contact protrusion, so as to avoid the rotating member 132 from shaking relative to the fixed member 131 when rotating.

[0169] In some embodiments, the surface of one end of the contact protrusion facing the first rotational fitting portion 1311 may be a smooth arc surface or a spherical surface, so that the friction between the contact protrusion and the surface of the first rotational fitting portion 1311 can be reduced.

[0170] Exemplarily, the wall of the rotating hole has a snap-fitting protrusion extending along its circumference and at least two contact portions 1323 spaced apart along its circumference, and the size of the contact portion 1323 protruding from the wall of the rotating hole is smaller than the size of the snap-fitting protrusion protruding from the wall of the rotating hole. In this way, the gap between the rotating hole and the rotating shaft is reduced by the contact portion 1323, thereby improving the problem of shaking when the rotating part 132 rotates. At the same time, the problem of interference between the contact portion 1323 and the rotating shaft can be avoided.

[0171] As another example, the surface of the contact protrusion facing one end of the rotating shaft can be an arc-shaped groove matching the rotating shaft, and the material of the contact protrusion can be made of a material with a certain elasticity, so that the contact protrusion can be released from the rotating shaft to further contact the gap between the protrusion and the rotating shaft, thereby further improving the stability of the rotating member 132 during self-rotation.

[0172] Please refer back to Figures 1 to 5 As shown, since at least part of the structure of the rotating member 132 in the corner assembly 130 protrudes beyond the outer contour of the anti-collision member 120, when the surface cleaning device 100 moves along the glass frame, the rotating member 132 rolls in contact with the glass frame, and the rag is usually set at the bottom end of the bottom plate 112 in the device body 110, and the contour of the rag coincides with the contour of the bottom plate 112. Therefore, when the surface cleaning device 100 moves along the glass frame and the rotating member 132 rolls with the glass frame, there is a certain gap between the contour of the rag and the edge of the glass, thus causing the problem of missing the area close to the glass frame.

[0173] Based on the above problems, in the embodiment of the present application, the corner assembly 130 also includes a corner cleaning member 160, which is arranged on the edge detection side of the device body 110, and at least part of the structure of the corner cleaning member 160 protrudes from the outer contour of the edge detection side of the device body 110, and protrudes from the outer contour of the boundary detection member 134 in a direction perpendicular to the surface of the body to be cleaned; when the corner cleaning member 160 moves with the surface cleaning device 100 to clean the surface to be cleaned, the boundary detection member 134 abuts against the surface to be cleaned, that is, the corner cleaning member 160 will not affect the contact between the boundary detection member 134 and the glass surface in a direction perpendicular to the glass surface, thereby improving the reliability of the boundary detection member 134 detecting changes in the position of the surface cleaning device 100; and the portion of the corner cleaning member 160 that protrudes from the outer contour of the device body 110 can clean the missed wiping area of ​​the glass near the frame as the surface cleaning device 100 moves, thereby improving the user experience.

[0174] In some embodiments, the dimension of the edge cleaning member 160 protruding from the outer contour of the device body 110 is not less than the dimension of the rotating member 132 protruding from the outer contour of the device body 110. In this way, the edge cleaning member 160 can completely cover the area between the outermost contour of the rotating member 132 and the outermost contour of the device body 110, so that the edge cleaning member 160 can solve the problem of missing wiping on the glass surface when cleaning the glass surface with the surface cleaning device 100.

[0175] In order to further improve the compactness of the overall structure of the surface cleaning device 100, in some embodiments, please refer to Figure 5 , Figure 6 , Figure 7 and Fig.11 As shown, the edge cleaning member 160 is disposed on the rotating member 132, and along the axial direction of the rotating member 132, at least a portion of the edge cleaning member 160 protrudes from the bottom end of the rotating member 132, so that the edge cleaning member 160 can fully contact the glass surface, thereby improving the cleaning effect of the edge cleaning member 160 on the glass surface.

[0176] In some embodiments, when the corner cleaning member 160 is disposed on the rotating member 132, the corner cleaning member 160 is disposed on at least one side of the boundary detection member 134; and when the corner cleaning member 160 is disposed only on one side of the boundary detection member 134, the path of movement of the boundary detection member 134 may have a problem of missing wiping. Therefore, in the embodiment of the present application, if Figures 5 to 7 , Fig.11 As shown, the corner cleaning member 160 is disposed around the outer periphery of the boundary detection member 134, so that the corner cleaning member 160 can clean any path that the boundary detection member 134 travels, so as to further reduce the missed wiping area.

[0177] In some embodiments, the edge and corner cleaning member has a plurality of cleaning portions 161, which are spaced apart at the bottom end of the rotating member 132, and each cleaning portion 161 protrudes outward from the bottom end of the rotating member 132. Exemplarily, the edge and corner cleaning member can be a cleaning brush, that is, the cleaning portion 161 is a brush for cleaning, so as to clean the glass surface by the brush.

[0178] For example, Figure 5 and Figure 6 As shown, multiple cleaning parts 161 form multiple cleaning groups, that is, multiple brush groups, and the multiple cleaning groups are arranged in sequence along the radial direction of the rotating part 132 from the center of the rotating part 132 to the outer peripheral side. Each cleaning group includes at least two cleaning parts 161, and at least two cleaning parts 161 in each cleaning group are arranged at intervals along the circumference of the rotating part 132.

[0179] In order to further improve the cleaning effect and avoid the problem of missed cleaning between adjacent cleaning parts 161, please continue to refer to Figure 5 and Figure 6 As shown, the cleaning parts 161 in each cleaning group are staggered with the cleaning parts 161 in the adjacent cleaning group in the circumferential direction of the rotating member 132, so that the cleaning area can be increased, thereby improving the phenomenon of missed wiping.

[0180] In order to improve the installation reliability between the corner cleaning member 160 and the rotating member 132, in the embodiment of the present application, please refer to Fig.11 As shown, the bottom wall of the rotating member 132 has a groove sunken toward the inner side of the rotating member 132, and the corner cleaning member 160 is fixedly connected to the bottom of the groove, that is, a plurality of cleaning portions 161 are respectively arranged in the groove and fixedly connected to the bottom of the groove, and part of the cleaning portion 161 protrudes from the bottom wall of the rotating member 132, so that the cleaning portion 161 protruding from the bottom of the rotating member 132 contacts the glass surface to achieve the purpose of cleaning the glass surface.

[0181] In some embodiments, the corner cleaning piece 160 may be deformed. When the corner cleaning piece 160 is deformed due to abutment against the surface to be cleaned (glass surface), the size of the corner cleaning piece 160 protruding from the bottom contour of the device body 110 after deformation is less than or equal to the size of the boundary detection piece 134 protruding from the bottom contour of the device body 110 when it is abutted against the glass surface, so as to ensure that when the surface cleaning device 100 moves on the glass surface, the boundary detection piece 134 is always in abutment against the glass surface, so as to ensure the working reliability of the boundary detection piece 134.

[0182] For example, Figure 7 and Fig.11As shown in the figure, the corner cleaning member 160 is a cleaning brush, which is a structure that protrudes from the bottom end of the device body 110. When suspended in the air, the size of the protrusion from the bottom end of the device body 110 is 1.5mm~2mm, and when the boundary detection member 134 abuts against the glass surface, the size of the boundary detection member 134 protruding from the bottom end of the device body 110 (i.e., the bottom end of the bottom plate 112) is, for example, 1mm~1.5mm. Exemplarily, when the boundary detection member 134 abuts against the glass surface, the size of the boundary detection member 134 protruding from the bottom end of the device body 110 (i.e., the bottom end of the bottom plate 112) is equal to the size of the corner cleaning member 160 protruding from the bottom end of the device body 110 and after deformation. In this way, while ensuring that the corner cleaning member 160 cleans the glass surface, the deformation of the corner cleaning member 160 can be avoided from interfering with the corner detection member in the horizontal direction, thereby avoiding the corner cleaning member 160.

[0183] In some embodiments, the deformability of the cleaning portion 161 decreases gradually along the direction from the surface of the cleaning portion 161 facing the glass to the surface away from the glass, that is, the hardness of the cleaning portion 161 increases gradually, so that the cleaning portion 161 has sufficient strength while cleaning the glass surface, thereby preventing the cleaning portion 161 from being excessively deformed and affecting the cleaning effect.

[0184] In order to further improve the strength of the cleaning part 161 near the bottom of the groove (i.e., the root of the brush), the cleaning part 161 has a reinforcement at the end near the bottom of the groove, and the reinforcement is embedded in the cleaning part 161 near the bottom of the groove. Exemplarily, the reinforcement can be made of a material with a certain strength such as metal embedded in the cleaning part 161, and the cleaning part 161 can be a silicone rod, a rubber rod or a cleaning bristle body that can clean the glass surface.

[0185] In addition, the cross-sectional dimension of the cleaning portion 161 is less than or equal to 0.1 mm. Exemplarily, the cross-sectional dimension of the cleaning portion 161 is 0.9 mm, so that the cleaning portion 161 has a certain strength while satisfying the cleaning effect, thereby extending the life of the cleaning portion 161.

[0186] Please refer to Figure 2 and Fig.12 As shown, in the surface cleaning device 100 provided in the embodiment of the present application, the walking component 200 can be a track 210 component, and the track 210 component includes a driving wheel 220, a driven wheel 230 and a track 210, wherein the driving wheel 220 and the driven wheel 230 are arranged in parallel and at intervals along the walking direction of the surface cleaning device 100, and the track 210 is wound around the driving wheel 220 and the driven wheel 230, so that when the motor drives the driving wheel 220 to rotate, the driving wheel 220 drives the driven wheel 230 to move through the track 210, and the track 210 contacts the glass surface, so that the surface cleaning device 100 walks along the glass surface through the track 210.

[0187] When cleaning the glass surface, users usually spray water on the glass surface first, or wet the rag before cleaning; or Fig.13 As shown, the glass surface cleaning device 100 is equipped with a water tank 180. The front and rear sides of the surface cleaning device 100 are both provided with water spraying parts connected to the water tank 180. The water spraying parts are, for example, nozzles. In this way, the water in the water tank 180 can be sprayed onto the glass surface through the nozzles. When the surface cleaning device 100 moves forward, the nozzle located on the front side of the surface cleaning device 100 sprays water onto the front glass, and the surface cleaning device 100 performs wet cleaning on the glass surface during the moving forward process; on the contrary, when the surface cleaning device 100 moves backward, the nozzle located on the rear side of the surface cleaning device 100 sprays water onto the rear glass, and the surface cleaning device 100 performs wet cleaning on the glass surface during the moving backward process, thereby improving the cleaning effect on the glass surface.

[0188] However, if there are pollutants or dirty water after cleaning on the glass surface, when the track 210 contacts the glass surface and moves along the glass surface, the pollutants or dirty water on the glass surface are easy to stick to the track 210, and the track 210 will pollute other surfaces of the glass when moving along the glass surface. In addition, if the track 210 is stuck with pollutants, it will also affect the smoothness of the track 210 moving on the glass surface.

[0189] Based on the above problems, in the embodiments of this application, please refer to Fig.12 As shown, the surface cleaning device 100 also includes a scraper 170, which is arranged at least on the front side of the walking component 200 along the walking direction of the device body 110 and is detachably connected to the device body 110. Along the width of the device body 110, part of the structure of the scraper 170 protrudes from the bottom wall of the device body 110 and can be deformed when it abuts against the glass surface. The size of the scraper 170 in the width direction of the device body 110 is larger than the size of the walking component 200 in the width direction of the device body 110. When the device body 110 moves along the surface to be cleaned, the scraper 170 is sealed and abutted against the surface to be cleaned and moves along the surface to be cleaned to prevent contaminants on the surface of the body to be cleaned from contacting the walking component 200.

[0190] It can be understood that in the embodiment of the present application, by arranging the scraping member 170 at least on the front side of the traveling component 200, when the surface cleaning device 100 moves forward, the scraping member 170 first scrapes off the pollutants and sewage on the glass surface, and the scraped pollutants and sewage are isolated on the side of the scraping member 170 away from the traveling component 200, so as to avoid the pollutants or sewage on the glass surface from contacting with the traveling component 200, thereby avoiding secondary contamination of the glass surface by the traveling component 200, and further improving the cleaning effect on the glass surface.

[0191] Please continue to refer to Fig.12 As shown, the front and rear sides of the walking component 200 are both provided with scraping parts 170, so that when the surface cleaning device 100 moves forward, the scraping part 170 on the front side first scrapes off the pollutants or sewage on the surface of the glass on the front side of the walking component 200; when the surface cleaning device 100 moves backward, the scraping part 170 on the rear side first scrapes off the pollutants or sewage on the surface of the glass on the rear side of the walking component 200, so that the walking component 200 will not contact the pollutants or sewage on the glass surface whether driving the surface cleaning device 100 forward or backward, thereby further improving the isolation effect of isolating the walking component 200 and the pollutants, thereby improving the cleaning effect on the glass surface.

[0192] It is understandable that, along the traveling direction of the traveling assembly 200 , a pollutant isolation zone is formed between the two scraping members 170 . When the surface cleaning device 100 moves forward or backward, the scraping member 170 is configured to isolate pollutants outside the pollutant isolation zone to prevent pollutants or sewage from sticking to the track 210 .

[0193] In addition, along the width direction of the surface cleaning device 100, which is, for example, a direction perpendicular to the traveling direction of the surface cleaning device 100, the width of the wiping area is greater than the width of the traveling component 200, that is, the front and rear wiping members 170 completely isolate the pollutants on the front and rear sides of the traveling component 200 outside the wiping area.

[0194] Exemplarily, the wiper member 170 may be a wiper plate. For example, the wiper plate may be made of a material having a certain elasticity, such as silicone material, rubber material, etc.

[0195] Thus, when the device body 110 moves along the surface to be cleaned, the portion of the scraper 170 protruding from the bottom wall of the device body 110 bends toward the side of the moving assembly 200 under the abutment force of the surface to be cleaned (eg, Fig.14 ), and seals against the surface to be cleaned to isolate pollutants on the side of the wiper member 170 facing away from the travel assembly 200, thereby improving the isolation effect of pollutants.

[0196] In some embodiments, please refer to Fig.14As shown, the device body 110 includes an upper cover 111 and a bottom plate 112 located below the upper cover 111, the upper cover 111 and the bottom plate 112 are jointly arranged to form a receiving cavity, the bottom plate 112 is provided with an avoidance notch 113, the walking component 200 and the wiper 170 are both installed in the receiving cavity, and part of the structures of the walking component 200 and the wiper 170 protrude outward from the outside of the bottom plate 112 through the avoidance notch 113; along the walking direction of the walking component 200, there is a gap between the wiper 170 and the mouth wall of the avoidance notch 113, and the gap is used to avoid deformation of the part of the wiper 170 protruding from the bottom plate 112, so that the part of the wiper 170 protruding from the bottom plate 112 has an avoidance space, so as to prevent the bottom end of the wiper 170 from interfering with the mouth wall of the avoidance notch 113 when deformed, thereby affecting the sealing between the wiper 170 and the glass surface.

[0197] Therefore, along the moving direction of the moving component 200, the gap between the scraper 170 and the mouth wall of the avoidance gap 113 is greater than the deformation amount of the scraper 170 protruding out of the bottom plate 112, so as to provide sufficient avoidance space for the deformation of the scraper 170, thereby improving the working reliability of the scraper 170.

[0198] Due to the long-term friction between the wiper component 170 and the glass surface, the wiper component 170 needs to be replaced after a certain period of use. Therefore, in order to improve the interchangeability of the wiper component 170, in an embodiment of the present application, the wiper component 170 is detachably installed in the installation cavity to facilitate the disassembly, assembly and replacement of the wiper component 170.

[0199] Exemplarily, the top of the wiper 170 has a first fixing portion 171 , and the installation cavity has a second fixing portion, and the first fixing portion 171 is detachably connected to the second fixing portion.

[0200] like Fig.15 As shown, the first fixing portion 171 can be a snap-in end, and the mounting cavity has a snap-in groove matching the snap-in end, and the snap-in end is snap-fitted with the snap-in groove, thereby realizing the detachable connection of the scraper 170; or, the second fixing portion can also be detachably mounted in the mounting cavity by means of a threaded connection; or, a magnet is provided on the first fixing portion 171, and a magnet is also provided on the second fixing portion, so that the scraper 170 can be installed in the mounting cavity by means of magnetic mutual adsorption, wherein the friction force between the scraper 170 and the glass surface is smaller than the magnetic adsorption force between the magnets, so that the scraper 170 will not fall off due to the friction between the scraper 170 and the glass surface.

[0201] In addition, as the wiper member 170 moves away from the glass surface and approaches it, at least one of the hardness and thickness of the wiper member 170 decreases successively, and the deformability increases successively. That is to say, the hardness of the top end of the wiper member 170 is greater than the hardness of the bottom end in contact with the glass surface, and the thickness of the top end of the wiper member 170 is greater than the thickness of the bottom end, so as to facilitate the deformation of the bottom end of the wiper member 170. In this way, while ensuring the wiper effect of the wiper member 170 and the sealing when in contact with the glass surface, the strength of the wiper member 170 can also be improved, thereby improving the working reliability and service life of the wiper member 170.

[0202] Please refer to Fig.15 As shown, the wiper 170 includes a first portion 172 and a second portion 173 connected in sequence. The first portion 172 protrudes from the bottom wall of the device body 110, and the second portion 173 is located inside the device body 110. The width of the first portion 172 is smaller than the width of the second portion 173. Along the width direction of the wiper 170, the side walls on both sides of the second portion 173 are respectively connected to the side walls on both sides of the first portion 172. The anti-stress structure 174 is provided to prevent the risk of stress concentration and breakage at the corners of the first portion 172 and the second portion 173. For example, in Fig.15 In the embodiment, the anti-stress structure 174 is an arc-shaped structure, for example, the anti-stress structure 174 is an arc-shaped structure to reduce stress concentration at the edge corners of the first portion 172 and the second portion 173 , thereby extending the service life of the wiper member 170 .

[0203] Please refer to Fig.14 As shown, the surface cleaning device 100 provided in the embodiment of the present application is provided with a water tank 180, and the water tank 180 has a liquid containing cavity, in which cleaning water for cleaning the glass is stored, wherein the water in the water tank 180 can be tap water, or a solution with detergents, fragrances or additives for decomposing dirt added to the water, which are collectively referred to as water in the embodiment of the present application.

[0204] The water tank 180 is usually disposed inside the surface cleaning device 100, and a water inlet 181 for filling water into the water tank 180 is disposed at the top of the water tank 180 (eg, Figures 16 to 19 As shown in ), the user is unable to know the amount of water stored in the water tank 180, which results in the user being unable to determine when to add water, resulting in a poor user experience.

[0205] In order to facilitate the user to know the amount of water stored in the water tank 180, especially to determine whether the water tank 180 is short of water, in the embodiment of the present application, please refer to Fig. 20As shown, a visual window is provided at the top of the water tank 180, and a floating member 183 is provided in the water tank 180. The floating member 183 can float up and down in the water tank 180 as the liquid level in the water tank 180 changes. That is to say, the position of the floating member 183 in the water tank 180 indicates the height of the water level in the water tank 180. In this way, the user can observe the position of the floating member 183 through the visual window to determine whether water needs to be added to the water tank 180; for example, when the floating member 183 is close to the top of the water tank 180, it indicates that the water in the water tank 180 is full and no water needs to be added. If the floating member 183 is located at the bottom of the water tank 180, it indicates that there is a lack of water in the water tank 180 and water needs to be added.

[0206] Exemplarily, the floating member 183 may be a structure such as a floating block or a floating ball that can float on the water surface.

[0207] In order to further ensure that the floating member 183 is within the visible range of the visual window, a floating space 182 connected to the liquid containing cavity is provided in the liquid containing cavity. The cross-sectional profile of the floating space 182 matches the cross-sectional profile of the floating member 183. The floating member 183 is located in the floating space 182 and floats up and down with the change of the liquid level in the floating space 182. In this way, it can be avoided that the floating member 183 is randomly offset in the water tank 180 and affects its visibility.

[0208] In some embodiments, a visible window is disposed at a position corresponding to the floating space 182 to improve the reliability of observing the floating member 183 in the floating space 182 through the visible window. In addition, the color of the floating member 183 is different from the color of water and the water tank 180. For example, the color of the floating member 183 is a more eye-catching red, yellow, green, etc. As long as it can be observed by the user, there is no limitation here.

[0209] Since the floating space 182 is relatively small, in order to make the floating member 183 float up and down with the change of the liquid level in the floating space 182, in the embodiment of the present application, the size of the floating member 183 in the first direction is larger than the size in the second direction, wherein the first direction is consistent with the height direction of the liquid containing chamber, and the second direction has an angle with the first direction, for example, the second direction is a direction perpendicular or approximately perpendicular to the first direction, so that the floating member 183 floats on the liquid surface under the action of a smaller liquid buoyancy, thereby ensuring that the water level change in the water tank 180 can be accurately detected by the floating member 183.

[0210] Exemplarily, the size of the floating member 183 in the first direction is less than or equal to 15 mm, and the maximum width of the floating member 183 in the second direction is less than or equal to 5 mm; for example, the floating member 183 may be an elliptical floating ball.

[0211] In addition, in order to further improve the smoothness of the up and down floating of the floating member 183, in the embodiment of the present application, the size of the top of the floating space 182 in the second direction is larger than the size of the bottom of the floating space 182 in the second direction; for example, along the height direction of the floating space 182, and from the bottom end to the top end of the floating space 182, the horizontal cross-sectional size of the floating space 182 increases successively, so that the floating member 183 can be prevented from getting stuck when floating up and down.

[0212] In some embodiments, the gap between the outer contour of the floating member 183 and the side wall of the floating space 182 is 0.2mm to 0.3mm, so that the floating member 183 can float up and down smoothly in the floating space 182 with the change of liquid level without causing the lateral gap to be too large and causing random floating laterally.

[0213] It can be understood that in the embodiment of the present application, by forming the cross-sectional profile of the floating space 182 into a structure that matches the cross-sectional profile of the floating member 183, the floating space 182 can guide the up and down floating of the floating member 183, and the floating member 183 is formed into an elliptical float structure, which can further improve the smoothness of the floating member 183 floating up and down with the liquid level.

[0214] In order to further improve the stability of the floating member 183 floating on the liquid surface, in the embodiment of the present application, the surface of the floating member 183 has a hydrophobic film, and the hydrophobic film is configured to overcome the tension of the liquid on the surface of the floating member 183, thereby improving the stability and reliability of the floating member 183 floating on the liquid surface.

[0215] In addition, in order to further improve the stability and reliability of the floating member 183 floating on the liquid surface, in the embodiment of the present application, the weight of the floating member 183 is 0.2g~0.3g to avoid the floating member 183 being too heavy and affecting the stability and reliability of the floating member 183 floating on the liquid surface.

[0216] In some embodiments, the top of the water tank 180 has a water filling port 181, and the water filling port 181 is provided with an openable and closable water filling cover 190, and the water filling cover 190 is connected to the water tank 180 through a guide rod, and the guide rod can move in a vertical direction relative to the water tank 180 so that the water filling cover 190 can be buckled on the water filling port 181 or removed from the water filling port 181. When water needs to be added to the water tank 180, the water filling cover 190 is opened to fill water into the water tank 180 through the water filling port 181; when water does not need to be added to the water tank 180, the water filling port 181 is closed by the water filling cover 190.

[0217] In addition, the visible window can be arranged on the water filling cover 190, so as to facilitate the processing and manufacturing of the visible window, reduce the difficulty of preparing the visible window, and thus reduce the processing cost.
