Description

Technical Field

[0001] The invention relates to the field of cleaning technology, in particular to a cleaning device. Background Art

[0002] As people's quality of life improves, more and more cleaning devices are entering thousands of households, and their labor-saving and convenient operation characteristics provide great convenience for people. Common cleaning devices include dry cleaning devices and wet cleaning devices. The wet cleaning device includes a cleaning mechanism and a liquid supply mechanism. The liquid supply mechanism is used to provide cleaning liquid to the cleaning cloth of the cleaning mechanism, so that the cleaning device can wash the surface to be cleaned.

[0003] At present, in the wet cleaning devices on the market, the liquid supply mechanism provides cleaning liquid to the cleaning belt at a constant flow rate and constant duration. This implementation has some problems. If the flow rate of the liquid supply mechanism is small, the liquid supply mechanism will take a long time to soak the cleaning belt. If the flow rate of the liquid supply mechanism is large, the water content of the cleaning belt will be too high, causing the floor to be slippery. In addition, in this case, the amount of cleaning liquid used is large, and the user needs to frequently replenish the cleaning liquid, which is not a good experience. Summary of the invention

[0004] In view of this, the present invention provides a cleaning device.

[0005] The cleaning device proposed by the present invention comprises:

[0006] Main frame;

[0007] A main cleaning component, mounted on the main frame and used for cleaning the surface to be cleaned and conveying garbage;

[0008] An introduction member connected to the main cleaning member or the main frame, the introduction member is arranged in front of the main cleaning member along the moving direction of the cleaning device, and the introduction member is at least used to guide the garbage on the surface to be cleaned to the main cleaning member;

[0009] a liquid supply mechanism, comprising a liquid storage tank and a spray assembly connected to the liquid storage tank, wherein the liquid storage tank is used to store cleaning liquid, and the spray assembly is used to drive the cleaning liquid in the liquid storage tank to spray on at least one of the main cleaning member, the introduction member and the surface to be cleaned; and

[0010] A controller is electrically connected to the spray assembly, and the controller is used to:

[0011] Acquiring a cleaning signal, wherein the cleaning signal includes a cleaning device start signal;

[0012] When the cleaning device start signal is obtained, the spray component is controlled to spray the cleaning liquid to the main cleaning component, the introduction component and at least one of the surface to be cleaned at a first flow rate, until a first threshold is reached, and the spray component is controlled to spray the cleaning liquid to the main cleaning component, the introduction component and at least one of the surface to be cleaned at a second flow rate, and the first flow rate is greater than the second flow rate.

[0013] It can be seen from the above technical scheme that the cleaning device proposed in the present invention, when the controller obtains the starting signal of the cleaning device, controls the spray component to first spray the cleaning liquid to the main cleaning component, the introduction component and at least one of the surfaces to be cleaned at a larger first flow rate until the first threshold is reached, and then controls the spray component to spray the cleaning liquid to the main cleaning component, the introduction component and at least one of the surfaces to be cleaned at a smaller first flow rate. In this way, after the cleaning device is turned on, the spray component first sprays the cleaning liquid at a larger flow rate, which can quickly soak the cleaning belt, save cleaning time, and improve cleaning efficiency. When the cleaning belt is soaked, the spray component sprays the cleaning liquid at a smaller flow rate, which can avoid the situation where the cleaning belt contains too much water and the ground is slippery. Moreover, in this embodiment, the cleaning liquid can be reasonably utilized according to different cleaning stages to avoid the problem of too fast consumption of the cleaning liquid and the user's need to frequently replenish the cleaning liquid, resulting in a poor user experience.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 7 As shown, an embodiment of the present invention proposes a cleaning device 100, and the cleaning device 100 proposed includes a main frame 10, a main cleaning component 20, an introduction component 30, a liquid supply mechanism 40 and a controller 50. The main cleaning component 20 is installed on the main frame 10 for cleaning the surface to be cleaned 200 and conveying garbage. The introduction component 30 is connected to the main cleaning component 20 or the main frame 10, and the introduction component 30 is arranged in front of the main cleaning component 20 along the moving direction of the cleaning device 100. The introduction component 30 is at least used to guide the garbage on the surface to be cleaned 200 to the main cleaning component 20. The liquid supply mechanism 40 includes a liquid storage tank 41 and a spray assembly 42 connected to the liquid storage tank 41, the liquid storage tank 41 is used to store cleaning liquid, and the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200. The controller 50 is electrically connected to the spray assembly 42, and the controller 50 is used to: obtain a cleaning signal, the cleaning signal includes a cleaning device 100 start signal; when the cleaning device 100 start signal is obtained, the spray assembly 42 is controlled to spray the cleaning liquid to at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200 at a first flow rate, until a first threshold is reached, and the spray assembly 42 is controlled to spray the cleaning liquid to at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200 at a second flow rate, and the first flow rate is greater than the second flow rate.

[0039] Among them, the moving direction of the cleaning device 100 can be understood as the forward direction of the cleaning device 100. For example, if the cleaning device 100 needs to be pushed by the user to move, then the moving direction can be understood as the corresponding direction when the user pushes the cleaning device 100 forward; if the cleaning device 100 is a self-moving device, then the moving direction can be understood as the moving direction of the self-moving device, that is, the main moving direction when the cleaning device 100 cleans the surface 200 to be cleaned. Of course, the cleaning device 100 will also retreat or turn in different scenes, but in the embodiments of the present application, the moving direction of the cleaning device 100 refers to the main running direction such as the forward direction of the cleaning device 100 and the user's pushing direction.

[0040] The surface to be cleaned 200 is the floor, that is, the cleaning device 100 is used to clean the floor. Of course, in other application scenarios, the surface to be cleaned 200 may also be a wall, a window, a ceiling, a glass surface, or other surfaces to be cleaned.

[0041] The introduction member 30 is mainly used to perform actions such as sweeping in garbage or obtaining garbage, so as to facilitate the main cleaning member 20 to better remove the garbage on the surface to be cleaned 200. When the cleaning device 100 cleans the surface to be cleaned 200, the cleaning device 100 moves forward along the surface to be cleaned 200, and the introduction member 30 located in the front contacts the garbage on the surface to be cleaned 200 and guides the garbage to the main cleaning member 20. The main cleaning member 20 cleans the surface to be cleaned 200 and transfers the garbage guided by the introduction member 30 to a preset position, thereby completing the cleaning of the garbage on the surface to be cleaned 200.

[0042] The cleaning liquid stored in the liquid storage tank 41 may be clean water, or a mixture of clean water, a detergent and / or a disinfectant, and the specific amount may be determined according to actual use requirements.

[0043] The cleaning device 100 proposed in the embodiment of the present invention, when the controller 50 obtains the start signal of the cleaning device 100, controls the spray component 42 to first spray the cleaning liquid to at least one of the main cleaning component 20, the introduction component 30 and the surface 200 to be cleaned at a larger first flow rate until the first threshold is reached, and then controls the spray component 42 to spray the cleaning liquid to at least one of the main cleaning component 20, the introduction component 30 and the surface 200 to be cleaned at a smaller first flow rate. In this way, after the cleaning device 100 is turned on, the spray component 42 first sprays the cleaning liquid at a larger flow rate, which can quickly soak the cleaning belt, save cleaning time, and improve cleaning efficiency. When the cleaning belt is soaked, the spray component 42 sprays the cleaning liquid at a smaller flow rate, which can avoid the situation where the cleaning belt contains too much water and the ground is slippery. In addition, in this embodiment, the cleaning liquid can be reasonably utilized according to different cleaning stages to avoid the problem that the cleaning liquid is consumed too quickly and the user needs to frequently replenish the cleaning liquid, resulting in a poor user experience.

[0044] In one embodiment, the first threshold is a preset duration. That is, in this embodiment, after the spray assembly 42 sprays at the first flow rate for a certain period of time, it automatically switches to the second flow rate to spray the cleaning liquid. For example, after the spray assembly 42 is controlled to spray the cleaning liquid to at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200 at the first flow rate for 8 seconds, the controller 50 controls the spray assembly 42 to spray the cleaning liquid to at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200 at the second flow rate. In this embodiment, the first threshold is set to the preset duration, the control logic is simple, debugging is convenient, and no complex detection system is required, which can save manpower and material costs.

[0045] It should be noted that the first threshold is not limited to being set to the above-mentioned preset time length. For example, in another embodiment, Figure 3 As shown, the introduction component 30 includes a first annular belt 31, and the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on the first annular belt 31. The first threshold is that the wetness of the first annular belt 31 reaches a preset value.

[0046] The wetness of the first endless belt 31 can be detected by setting a humidity sensor. Of course, the wetness of the first endless belt 31 is not limited to being detected by a humidity sensor. For example, in some other embodiments, the introduction member 30 also includes a first motor for driving the first endless belt 31 to rotate, and the wetness of the first endless belt 31 can be detected by detecting the rotational resistance of the first motor. It can be understood that the more cleaning liquid is infiltrated on the first endless belt 31, the heavier the first endless belt 31 will become, and the greater the resistance of the first motor to drive the first endless belt 31 to rotate will be. Therefore, the wetness of the first endless belt 31 can be detected by detecting the rotational resistance of the first motor.

[0047] It should be noted that the first threshold is not limited to being set to the above-mentioned preset time length. For example, in another embodiment, Figure 3 As shown, the main cleaning component 20 includes a second annular belt 21, and the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on the second annular belt 21. The first threshold is that the wettability of the second annular belt 21 reaches a preset value. The wettability of the second annular belt 21 can be detected by referring to the detection method of the first annular belt 31, which will not be described in detail here.

[0048] like Figure 3As shown, in one embodiment, the introduction member 30 includes a first endless belt 31 and a first driving assembly 32 connected to the first endless belt 31, the first driving assembly 32 is used to drive the first endless belt 31 to rotate, the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on the first endless belt 31, the controller 50 is electrically connected to the first driving assembly 32, and the controller 50 is also used to: when the spray assembly 42 sprays the cleaning liquid to the first endless belt 31 at a first flow rate, control the first driving assembly 32 to drive the first endless belt 31 to rotate at a first speed; when the spray assembly 42 sprays the cleaning liquid to the first endless belt 31 at a second flow rate, control the first driving assembly 32 to drive the first endless belt 31 to rotate at a second speed; the second speed is greater than the first speed.

[0049] In this embodiment, the flow rate of the cleaning liquid sprayed by the spray assembly 42 can match the operation stage of the first endless belt 31. When the first endless belt 31 is in the first stage of infiltration, the spray assembly 42 sprays more cleaning liquid, and correspondingly, the first endless belt 31 rotates slower, which can achieve a better infiltration effect. When the first endless belt 31 is in the second stage of cleaning the surface 200 to be cleaned, the first endless belt 31 rotates faster, which can achieve a better cleaning effect on the surface 200 to be cleaned and improve the cleaning efficiency.

[0050] like Figure 3 As shown, in one embodiment, the main cleaning component 20 includes a second endless belt 21 and a second driving assembly 22 connected to the second endless belt 21, the second driving assembly 22 is used to drive the second endless belt 21 to rotate, the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on the second endless belt 21, the controller 50 is electrically connected to the second driving assembly 22, and the controller 50 is also used to: when the spray assembly 42 sprays the cleaning liquid to the second endless belt 21 at a first flow rate, control the second driving assembly 22 to drive the second endless belt 21 to rotate at a first speed; when the spray assembly 42 sprays the cleaning liquid to the second endless belt 21 at a second flow rate, control the second driving assembly 22 to drive the second endless belt 21 to rotate at a second speed; the second speed is greater than the first speed. Similarly, in this embodiment, the flow rate of the cleaning liquid sprayed by the spray assembly 42 can match the operation stage of the second endless belt 21, so that the cleaning liquid sprayed by the spray assembly 42 can better infiltrate the second endless belt 21, and improve the cleaning efficiency and effect.

[0051] like Figure 4As shown, in one embodiment, the spray assembly 42 includes a pump 421, a pipeline 422 and a spray part 423. The pump 421 is connected to the liquid storage tank 41 through the pipeline 422, and the spray part 423 is connected to the pump 421 through the pipeline 422. The controller 50 is electrically connected to the pump 421, and the controller 50 is used to control the pump 421 to control the water flow rate of the spray part 423 to switch between the first flow rate and the second flow rate. For example, the controller 50 controls the speed of the impeller of the pump 421 to switch the water flow rate of the spray part 423 between the first flow rate and the second flow rate. Specifically, when the spray part 423 needs to discharge water at the first flow rate, the speed of the impeller is controlled to be faster, and when the spray part 423 needs to discharge water at the second flow rate, the speed of the impeller is controlled to be slower.

[0052] Of course, it is not limited to the above-mentioned implementation mode. For example, in another embodiment, Figure 5 As shown, the spray assembly 42 includes a pump 421, a valve 424, a spray piece 423 and a pipeline 422. The pump 421 is connected to the liquid storage tank 41 through the pipeline 422, and the spray piece 423 is connected to the pump 421 through the pipeline 422. The valve 424 is arranged on the pipeline 422 between the liquid storage tank 41 and the pump 421 or on the pipeline 422 between the pump 421 and the spray piece 423. The pump 421 and / or the valve 424 are electrically connected to the controller 50. The controller 50 is used to control the opening of the pump 421 and / or the valve 424 to control the water outlet flow rate of the spray piece 423 to switch between the first flow rate and the second flow rate. That is, in this embodiment, the controller 50 can control the water outlet flow rate of the spray element 423 to switch between the first flow rate and the second flow rate by controlling the pump 421 alone, or can control the water outlet flow rate of the spray element 423 to switch between the first flow rate and the second flow rate by controlling the opening of the valve 424 alone, or can control the water outlet flow rate of the spray element 423 to switch between the first flow rate and the second flow rate by controlling the opening of the pump 421 and the valve 424 at the same time.

[0053] Of course, it is not limited to the above-mentioned implementation mode. For example, in another embodiment, Figure 6 As shown, the spray assembly 42 includes a valve 424, a spray part 423 and a pipeline 422. The valve 424 is arranged on the pipeline 422 between the liquid storage tank 41 and the spray part 423. The valve 424 is electrically connected to the controller 50. The controller 50 is used to control the opening of the valve 424 to control the water flow rate of the spray part 423 to switch between the first flow rate and the second flow rate. That is, in this embodiment, the spray assembly 42 allows the cleaning liquid to flow to the spray part 423 by its own gravity and then be sprayed out.

[0054] In one embodiment, the cleaning signal also includes a floor scrubbing mode signal, and the controller 50 is further used to: when the floor scrubbing mode signal is obtained, control the spray assembly 42 to spray the cleaning liquid at the first flow rate to at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200, until the first threshold is reached, and then control the spray assembly 42 to spray the cleaning liquid at the second flow rate to at least one of the main cleaning component 20, the introduction component 30 and the surface to be cleaned 200. That is, the controller 50 can be used to simultaneously obtain the power-on signal of the cleaning device 100 and the floor scrubbing mode signal. When the controller 50 obtains one of the power-on signal of the cleaning device 100 and the floor scrubbing mode signal, the spray assembly 42 is controlled to spray the cleaning liquid at the first flow rate, and after reaching the first threshold, the cleaning liquid is sprayed at the second flow rate.

[0055] In one embodiment, the cleaning device 100 includes an input component (not shown), which is installed on the main frame 10 and electrically connected to the controller 50. The user inputs a floor washing mode instruction to the cleaning device 100 through the input component, and the input component generates a floor washing mode signal according to the floor washing mode instruction input by the user. The input component can be but is not limited to a button, a voice input device, a gesture input device, or a touch screen.

[0056] In one embodiment, the cleaning signal also includes a self-cleaning mode signal, and the controller 50 is also used to: when the self-cleaning mode signal is obtained, control the spray assembly 42 to spray the cleaning liquid to the main cleaning component 20 and / or the introduction component 30 at a third flow rate, and the third flow rate is greater than the first flow rate. In this embodiment, when the cleaning device 100 enters the self-cleaning mode, the controller 50 controls the spray assembly 42 to spray the cleaning liquid to the main cleaning component 20 and / or the introduction component 30 at a third flow rate greater than the first flow rate. In this way, in the self-cleaning mode, more cleaning liquid is sprayed to the main cleaning component 20 and / or the introduction component 30, which can effectively and quickly clean the main cleaning component 20 and / or the introduction component 30, thereby improving the cleaning efficiency. The user can input the self-cleaning mode instruction to the cleaning device 100 through the above-mentioned input component.

[0057] like Figure 3As shown, in one embodiment, the introduction member 30 includes a first endless belt 31 and a first driving assembly 32 connected to the first endless belt 31, the first driving assembly 32 is used to drive the first endless belt 31 to rotate, the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on the first endless belt 31, and the controller 50 is electrically connected to the first driving assembly 32. The controller 50 is also used to: when the spray assembly 42 sprays the cleaning liquid to the first endless belt 31 at a third flow rate, control the first driving assembly 32 to drive the first endless belt 31 to rotate at a third speed, and the third speed is greater than the second speed. In this embodiment, in the self-cleaning mode, by controlling the rotation speed of the first endless belt 31 to increase, the self-cleaning time of the cleaning device 100 can be reduced and the cleaning efficiency can be improved.

[0058] like Figure 3 As shown, in one embodiment, the main cleaning component 20 includes a second endless belt 21 and a second driving assembly 22 connected to the second endless belt 21, the second driving assembly 22 is used to drive the second endless belt 21 to rotate, the spray assembly 42 is used to drive the cleaning liquid in the liquid storage tank 41 to spray on the second endless belt 21, and the controller 50 is electrically connected to the second driving assembly 22. The controller 50 is also used to: when the spray assembly 42 sprays the cleaning liquid to the second endless belt 21 at a third flow rate, control the second driving assembly 22 to drive the second endless belt 21 to rotate at a third speed, and the third speed is greater than the second speed. In this embodiment, in the self-cleaning mode, by controlling the speed of the second endless belt 21 to speed up, the self-cleaning time of the cleaning device 100 can be reduced and the cleaning efficiency can be improved.

[0059] In one embodiment, the cleaning device 100 further includes a prompting mechanism (not shown), which is electrically connected to the controller 50. The controller 50 is further configured to control the prompting mechanism to issue a prompt to the user when the first threshold is reached. In this embodiment, by providing the prompting mechanism to issue a prompt to the user, the user can understand the current operating status of the cleaning device 100.

[0060] In one embodiment, the prompt mechanism includes at least one monochrome display light, and the display light prompts the user by emitting light. Of course, the prompt mechanism is not limited to the above-mentioned embodiments. For example, in another embodiment, the prompt mechanism includes at least one multicolor display light, and the display light prompts the user by emitting lights of different colors. Of course, the prompt mechanism is not limited to the above-mentioned embodiments. For example, in another embodiment, the prompt mechanism includes a buzzer or a voice broadcast device, and the buzzer or the voice broadcast device prompts the user by emitting sound. Of course, the prompt mechanism is not limited to the above-mentioned embodiments. For example, in another embodiment, the prompt mechanism includes a display screen, and the display screen prompts the user by displaying text / patterns.

[0061] like Figure 3As shown, in one embodiment, the cleaning device 100 further includes a recovery container 60, which is arranged behind the main cleaning component 20 along the forward direction of the cleaning device 100, and the recovery container 60 is used to collect the garbage transferred from the main cleaning component 20. Specifically, during the use of the cleaning device 100, there is a garbage conveying channel between the main cleaning component 20 and the introduction component 30, and the main cleaning component 20 cooperates with the introduction component 30 to pick up the garbage and drive the garbage into the garbage conveying channel for conveying, and the garbage enters the recovery container 60 after being conveyed along the garbage conveying channel.

[0062] like Figure 3 As shown, in one embodiment, the cleaning device 100 also includes a scraper assembly 70, which is disposed at the rear end of the main cleaning component 20 and / or the rear end of the introduction component 30, and the scraper assembly 70 is used to abut the first annular belt 31 and / or the second annular belt 21. After the sticky garbage on the first annular belt 31 and / or the second annular belt 21 hits the scraper assembly 70, it detaches from the first annular belt 31 and / or the second annular belt 21 and falls into the recovery container 60.

[0063] like Figure 3 and Figure 8 As shown, in one embodiment, the main cleaning component 20 has a first side portion M1 arranged adjacent to the introduction component 30, and the introduction component 30 has a second side portion M2 adjacent to the main cleaning component 20 and arranged opposite to the first side portion M1, and the first side portion M1 and the second side portion M2 are both inclined, and the first side portion M1 and the second side portion M2 are used to cooperate in conveying garbage.

[0064] In this embodiment, by setting the first side portion M1 and the second side portion M2 for cooperating in conveying garbage, the cleaning device 100 proposed in this embodiment can remove garbage on the surface to be cleaned 200 without the drive of an exhaust fan, that is, the exhaust fan is omitted, thereby effectively reducing the noise, power consumption and cost of the cleaning device 100. In addition, by setting the first side portion M1 and the second side portion M2 to be inclined, it is conducive to the garbage being smoothly conveyed upward under the clamping of the first side portion M1 and the second side portion M2, and the garbage will not fall down, thereby improving the reliability of the first side portion M1 and the second side portion M2 in conveying garbage.

[0065] In one embodiment, the inclination angle of the first side portion M1 relative to the surface to be cleaned 200 is r, wherein 20°≤r≤70°. Optionally, the inclination angle of the first side portion M1 relative to the surface to be cleaned 200 is 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, or the inclination angle of the first side portion M1 relative to the surface to be cleaned 200 is any value between the two adjacent values ​​mentioned above. With this embodiment, not only the height of the recycling container 60 can be made larger, but also the transmission capacity of the garbage can be improved. It can be understood that the larger the inclination angle of the first side portion M1, the greater the difficulty of garbage transportation, but under the limited transportation length, the higher the height of its transportation. On the contrary, the smaller the inclination angle of the first side portion M1 is, the easier it is to transport the garbage. However, within a limited transportation length, the transportation height is lower. Therefore, setting the inclination angle of the first side portion M1 within a corresponding range can effectively increase the transportation height, which not only allows the height of the recycling container 60 to be larger, but also improves the garbage transportation capacity.

[0066] In one embodiment, the first side portion M1 extends obliquely from the position of the main cleaning member 20 close to the surface to be cleaned 200 toward the upper rear of the cleaning device 100, and the second side portion M2 extends obliquely from the position of the introduction member 30 close to the surface to be cleaned 200 toward the upper rear of the cleaning device 100. The upper rear refers to the rear area in the moving direction of the cleaning device 100 and the upper area in the height direction of the cleaning device 100. In this embodiment, the first side portion M1 is mainly used to carry and transport garbage, and the second side portion M2 is mainly used to press the garbage against the first side portion M1 and can be used to transport garbage.

[0067] In one embodiment, at least a portion of the first side portion M1 and at least a portion of the second side portion M2 are parallel to each other. In this embodiment, the first side portion M1 and the second side portion M2 can better clamp and convey garbage. Of course, in a specific application, the first side portion M1 and the second side portion M2 may not be parallel to each other.

[0068] In one embodiment, when the cleaning device 100 is cleaning garbage from the surface to be cleaned 200, the introduction member 30 can adjust the gap between the introduction member 30 and the main cleaning member 20 according to the size of the garbage. In this embodiment, the cleaning device 100 can remove garbage of different sizes.

[0069] In one embodiment, the introduction member 30 is rotatably connected to the main cleaning member 20 or the recovery container 60. When the introduction member 30 hits the garbage, the introduction member 30 rotates relative to the main cleaning member 20 or the recovery container 60, so that the gap between the introduction member 30 and the main cleaning member 20 can be adjusted. Optionally, the introduction member 30 is rotatably connected to the main cleaning member 20 or the recovery container 60 through a connecting rod mechanism.

[0070] like Fig. 9 As shown, in one embodiment, the introduction member 30 includes a first motor 35, a first roller 33, a second roller 36 and a first endless belt 31, the first endless belt 31 is wrapped around the first roller 33 and the second roller 36, the first motor 35 is connected to the first roller 33 or the second roller 36, and the first motor 35 is used to drive the first roller 33 or the second roller 36 to rotate to drive the first endless belt 31 to rotate, so as to clean the surface 200 to be cleaned.

[0071] like Fig. 9 As shown, in one embodiment, the second roller 36 is located obliquely above the first roller 33, and the first endless belt 31 includes a first extension section 311, a second extension section 312, a third extension section 313 and a fourth extension section 314 along the circumferential direction. The first extension section 311 abuts against the first roller 33, and the second extension section 312 abuts against the second roller 36. The third extension section 313 and the fourth extension section 314 are located between the first extension section 311 and the second extension section 312 and are arranged oppositely. When the first endless belt 31 rotates, the third extension section 313 moves from the second roller 36 toward the first roller 33, and the fourth extension section 314 moves from the first roller 33 toward the second roller 36. The cleaning device 100 also includes a wiper 80, which is arranged on the outer side of the first endless belt 31 and interferes with the second extension section 312. The wiper 80 is used to scrape out the sewage attached to the first endless belt 31.

[0072] In one embodiment, the outer side of the first annular belt 31 includes a fluff layer, and the interference amount between the wiper 80 and the first annular belt 31 is greater than or equal to 30% of the thickness of the fluff layer and less than or equal to 80% of the thickness of the fluff layer. It should be noted that the fluff of the fluff layer may be dry or wet, wherein the interference amount can be understood as the depth of the wiper 80 abutting against the fluff layer when the fluff is dry, or refers to the amount of intersection between the dry fluff and the fluff layer, thereby improving the cleanliness of the first annular belt 31.

[0073] like Fig. 9As shown, in one embodiment, the horizontal plane where the central axis L of the second roller 36 is located is taken as the reference plane S, the wiper 80 is located above the reference plane S, and the angle between the line from the contact point between the wiper 80 and the first endless belt 31 to the central axis L and the reference plane S is α, wherein 30°≤α≤120°, so that the dirty water scraped by the wiper 80 forms a water mass W between the wiper 80 and the first endless belt 31 for re-wetting the first endless belt 31. That is, in this embodiment, the dirty water scraped by the wiper 80 will not be directly scraped away by the wiper 80, but will be retained on the first endless belt 31 to re-wet the first endless belt 31, thereby avoiding the situation that the cleaning liquid sprayed by the spray assembly 42 on the first endless belt 31 is scraped away by the wiper 80 before it has wetted the first endless belt 31, resulting in a waste of cleaning liquid, and a better wetting effect on the first endless belt 31 can also be achieved.

[0074] In one embodiment, the angle between the line from the contact point of the wiper element 80 and the first annular belt 31 to the central axis L and the reference plane S is 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, or 120°, or the angle between the line from the contact point of the wiper element 80 and the first annular belt 31 to the central axis L and the reference plane S is any value between the above two adjacent values.

[0075] In one embodiment, the spraying member 423 is disposed opposite to the third extension section 313, and the spraying member 423 is used to spray the cleaning liquid onto the third extension section 313. The spraying member 423 sprays the cleaning liquid onto the third extension section 313, and the third extension section 313 needs to rotate a long distance before running to the wiper member 80. That is, in this embodiment, the cleaning liquid stays on the first endless belt 31 for a long time before hitting the wiper member 80, which is conducive to the cleaning liquid infiltrating the first endless belt 31.

[0076] In one embodiment, the spraying member 423 is disposed close to the wiper member 80. In this embodiment, the residence time of the cleaning liquid on the first endless belt 31 before hitting the wiper member 80 can be maximized, so that the first endless belt 31 has a better wetting effect.

[0077] like Fig.10 and Fig.11As shown, in one embodiment, the first motor 35 is located inside the first roller 33. In this embodiment, by arranging the first motor 35 inside the first roller 33, not only can the downward pressure of the first endless belt 31 be maximized, so that the first endless belt 31 can have a better cleaning effect on the ground. Moreover, the first motor 35 can be installed in a hidden manner, so that the structure of the introduction member 30 is more compact and the mechanism is more concise. In addition, the first motor 35 and the first roller 33 can be arranged as an integral module for easy assembly. In addition, since the first motor 35 needs to be arranged inside the first roller 33, the diameter of the first roller 33 needs to be set relatively large, which can improve the obstacle crossing ability of the first roller 33 and realize the cleaning of larger garbage.

[0078] like Fig.10 and Fig.11 As shown, in one embodiment, the introduction member 30 further includes a first bracket 37, the first motor 35 includes a first body 351 and a first drive shaft 352, and the first body 351 is connected to the first bracket 37. The first roller 33 includes a first shaft 331 and a first cylinder 332, the first shaft 331 includes a first end A1 and a second end opposite to the first end A1, the first end A1 of the first shaft 331 is rotatably connected to the first bracket 37, the second end of the first shaft 331 is connected to the first drive shaft 352 of the first motor 35, the first cylinder 332 is sleeved outside the first shaft 331 and the first motor 35 and connected to the first shaft 331, and the first annular belt 31 abuts against the outer wall of the first cylinder 332. That is, the first body 351 and the first bracket 37 remain relatively motionless, and during operation, the first drive shaft 352 rotates to drive the first shaft 331 to rotate, the first shaft 331 drives the first cylinder 332 to rotate, and the first cylinder 332 drives the first annular belt 31 to rotate.

[0079] It should be noted that the first motor 35 is not limited to the above connection method. For example, in some other embodiments, Fig.12 As shown, the first driving shaft 352 of the first motor 35 is connected to the first bracket 37, and the first body 351 of the first motor 35 is connected to the second end of the first rotating shaft 331, that is, when the first motor 35 is running, the first driving shaft 352 and the first bracket 37 remain stationary together, and the first body 351 rotates to drive the first rotating shaft 331 to rotate.

[0080] It should be noted that the first end and the second end of the first rotating shaft 331 are integrally formed. Of course, the configuration is not limited to the above. For example, in some other embodiments, Fig.10 and Fig.11As shown, the first end A1 and the second end A2 of the first rotating shaft 331 are separately arranged, and the first bracket 37 includes a first side plate 371 and a second side plate 372 opposite to the first side plate 371. The first end A1 of the first rotating shaft 331 is rotatably connected to the first side plate 371, the first body 351 is connected to the second side plate 372, and the second end A2 of the first rotating shaft 331 is rotatably connected to the first body 351 or the second side plate 372, which can be determined according to actual design requirements.

[0081] It should be noted that the connection between the first motor 35 and the first roller 33 is not limited to the above-mentioned method. For example, in another embodiment, Fig.10 and Fig.13 As shown, the introduction member 30 further includes a first bracket 37, the first motor 35 includes a first body 351, a first drive shaft 352 and a second drive shaft 353, the first body 351 is mounted on the first bracket 37, the first body 351 includes a first side and a second side opposite to the first side, the first drive shaft 352 is arranged on the first side of the first body 351, and the second drive shaft 353 is arranged on the second side of the first body 351. There are two first rollers 33, one of which is located on the first side of the first body 351 and connected to the first drive shaft 352, and the other first roller 33 is arranged on the second side of the first body 351 and connected to the second drive shaft 353. That is, when the first motor 35 is running, it drives the first drive shaft 352 and the second drive shaft 353 to rotate synchronously, and the first drive shaft 352 and the second drive shaft 353 respectively drive the two first rollers 33 to rotate. In this embodiment, the interaction force between the first motor 35 and the two first rollers 33 is relatively balanced, thereby avoiding the situation where a deflection force occurs on one side of the first roller 33 when the first motor 35 is started, causing the introduction member 30 to deviate to one side as a whole. This allows the introduction member 30 to operate stably, and the first annular belt 31 can better fit the surface 200 to be cleaned, thereby achieving a better cleaning effect.

[0082] It should be noted that the connection between the first motor 35 and the first roller 33 is not limited to the above-mentioned method. For example, in another embodiment, Fig.10 and Fig.14As shown, the introduction member 30 also includes a first bracket 37, and the first bracket 37 includes a first side plate 371 and a second side plate 372 opposite to the first side plate 371. The first motor 35 includes a first body 351, a first drive shaft 352 and a second drive shaft 353. The first body 351 includes a first side and a second side opposite to the first side. The first drive shaft 352 is arranged on the first side of the first body 351, and the second drive shaft 353 is arranged on the second side of the first body 351. The first drive shaft 352 is connected to the first side plate 371, and the second drive shaft 353 is connected to the second side plate 372. The first roller 33 is sleeved outside the first motor 35 and connected to the first body 351. That is, the first drive shaft 352 and the first bracket 37 remain fixed, and the second drive shaft 353 and the first bracket 37 remain fixed, and the first body 351 rotates to drive the first roller 33 to rotate. This embodiment can simplify the structure, and the overall structure of the first motor 35 and the first roller 33 is more concise, with lower cost and convenient assembly. The output torque of the first motor 35 on the first roller 33 can be relatively balanced, thereby avoiding the situation where a deflection force occurs on one side of the first roller 33 when the first motor 35 is started, thereby causing the entire introduction member 30 to deviate to one side.

[0083] It should be noted that the connection between the first motor 35 and the first roller 33 is not limited to the above-mentioned method. For example, in another embodiment, Fig.10 and Fig.15As shown, the introduction member 30 also includes a first bracket 37, and the first roller 33 includes a first end and a second end opposite to the first end. There are two first motors 35, and the two first motors 35 are respectively a first drive motor 35a and a second drive motor 35b, the first drive motor 35a includes a first body 351 and a first drive shaft 352, and the second drive motor 35b includes a second body 354 and a second drive shaft 353, the first body 351 is connected to the first bracket 37, the first drive shaft 352 is connected to the first end of the first roller 33, the second body 354 is connected to the first bracket 37, and the second drive shaft 353 is connected to the second end of the first roller 33, and the first drive motor 35a and the second drive motor 35b synchronously drive the first roller 33 to rotate. That is, the first body 351 and the first bracket 37 remain stationary, and the second body 354 and the first bracket 37 remain stationary. When running, the first drive shaft 352 and the second drive shaft 353 rotate, and the first roller 33 is synchronously driven to rotate. In this embodiment, the interaction force between the first motor 35 and the two first rollers 33 is relatively balanced, so that the introduction member 30 can run stably, and the first endless belt 31 can be better fitted with the surface to be cleaned 200, thereby achieving a better cleaning effect. In addition, the output torque force of the first motor 35 on the first roller 33 can be relatively balanced, thereby avoiding the situation where a deflection force occurs on one side of the first roller 33 when the first motor 35 is started, thereby causing the introduction member 30 to deviate to one side as a whole.

[0084] It should be noted that the connection between the first motor 35 and the first roller 33 is not limited to the above-mentioned method. For example, in another embodiment, Fig.10 and Fig.16As shown, the introduction member 30 also includes a first bracket 37, the first roller 33 includes a first rotating shaft 331 and a first cylinder 332, the first rotating shaft 331 includes a first end and a second end opposite to the first end. The number of the first motor 35 is two, the two first motors 35 are respectively a first drive motor 35a and a second drive motor 35b, the first drive motor 35a includes a first body 351 and a first drive shaft 352, the second drive motor 35b includes a second body 354 and a second drive shaft 353, the first body 351 is connected to the first bracket 37, the first drive shaft 352 is connected to the first end of the first rotating shaft 331, the second body 354 is connected to the first bracket 37, and the second drive shaft 353 is connected to the second end of the first rotating shaft 331. The first cylinder 332 is sleeved outside the first rotating shaft 331, at least part of the first body 351 and at least part of the second body 354, the first cylinder 332 is connected to the first rotating shaft 331, and the first annular belt 31 abuts against the outer side wall of the first cylinder 332. As described above, the first body 351 and the first bracket 37 remain stationary, and the second body 354 and the first bracket 37 remain stationary. During operation, the first drive shaft 352 and the second drive shaft 353 rotate, and synchronously drive the first roller 33 to rotate. In this embodiment, by arranging at least part of the first body 351 and at least part of the second body 354 in the first cylinder 332, the overall structure composed of the first drive motor 35a, the second drive motor 35b and the first roller 33 is made more concise. And the output torsional force of the first motor 35 on the first roller 33 can be relatively balanced, thereby avoiding the situation that the first roller 33 has a deflection force when the first motor 35 is started, thereby causing the entire introduction member 30 to deviate to one side.

[0085] It should be noted that the connection between the first motor 35 and the first roller 33 is not limited to the above-mentioned method. For example, in another embodiment, Fig.10 and Fig.17As shown, the introduction member 30 further includes a first bracket 37, and the first roller 33 includes a first end and a second end opposite to the first end. There are two first motors 35, and the two first motors 35 are respectively a first drive motor 35a and a second drive motor 35b, the first drive motor 35a includes a first body 351 and a first drive shaft 352, and the second drive motor 35b includes a second body 354 and a second drive shaft 353, the first body 351 is at least partially disposed in the first roller 33 and connected to the first end of the first roller 33, the first drive shaft 352 is connected to the first bracket 37, at least partially the second body 354 is disposed in the first roller 33 and connected to the second end of the first roller 33, and the second drive shaft 353 is connected to the first bracket 37. That is, the first drive shaft 352 and the first bracket 37 remain relatively stationary, and the second drive shaft 353 and the first bracket 37 remain relatively stationary. During operation, the first body 351 and the second body 354 rotate to drive the first roller 33 to rotate. Furthermore, the output torque force of the first motor 35 on the first roller 33 can be relatively balanced, thereby avoiding a deflection force on one side of the first roller 33 when the first motor 35 is started, thereby preventing the entire introduction member 30 from deflecting to one side.

[0086] like Fig.18 As shown, in one embodiment, the introduction member 30 is formed with an introduction slope 30a, which extends from the end of the introduction member 30 close to the surface to be cleaned 200 in a direction gradually away from the main cleaning member 20 and the surface to be cleaned 200. The introduction slope 30a is used to guide the garbage on the surface to be cleaned 200 to the main cleaning member 20 or the working area of ​​the main cleaning member 20.

[0087] Among them, the introduction slope 30a extends from the end of the introduction component 30 close to the surface to be cleaned 200 in a direction gradually away from the main cleaning component 20 and the surface to be cleaned 200, that is, the introduction slope 30a extends obliquely from the bottom of the introduction component 30 toward the upper front of the cleaning device 100 in a flared shape, and the end of the introduction slope 30a away from the main cleaning component 20 is the part where the distance from the introduction slope 30a to the surface to be cleaned 200 is the largest.

[0088] During the forward movement of the cleaning device 100, since the end of the introduction slope 30a away from the main cleaning component 20 is the part where the distance between the introduction slope 30a and the surface to be cleaned 200 is the largest, the end of the introduction slope 30a away from the main cleaning component 20 first contacts the garbage, so that larger garbage can enter between the introduction slope 30a and the surface to be cleaned 200, and the introduction slope 30a extends downward, which is conducive to better guiding the garbage to the main cleaning component 20 or the working area of ​​the main cleaning component 20.

[0089] In one embodiment, the introduction member 30 includes a first roller 33, a first endless belt 31 and at least one first guide component 34. The first endless belt 31 is rotatably wrapped around the first roller 33 and the first guide component 34. The first endless belt 31 is formed with an introduction slope 30a.

[0090] The first endless belt 31 is rotatably wrapped around the first roller 33 and the first guide component 34 , which means that the first endless belt 31 not only wraps around the first roller 33 and the first guide component 34 , but also can rotate relative to the first roller 33 and the first guide component 34 .

[0091] In one embodiment, the first roller 33 can rotate freely around its own central axis under the action of external force. The first roller 33 rotates under the drive of external force, thereby driving the first endless belt 31 to rotate.

[0092] In one embodiment, the first guide member 34 is at least one of a roller, a rod whose at least partial outer surface is cylindrical, or a non-circular member whose partial outer surface is arc-shaped.

[0093] In one embodiment, at least one first guide member 34 is a roller, which can rotate freely around its own central axis under the action of external force. Its specific structure can refer to the first roller 33, and will not be described in detail here. Here, the first guide member 34 is a roller, which can make the first guide member 34 not only support, tension and guide the first endless belt 31, but also reduce the resistance generated by the first guide member 34 to the first endless belt 31 during the rotation of the first endless belt 31, which is conducive to improving the smoothness of the rotation of the first endless belt 31. Of course, the arrangement of the first guide component 34 is not limited to this. For example, as an alternative embodiment, the first guide component 34 is a rod body whose outer surface is at least partially cylindrical, and the first annular belt 31 contacts the cylindrical outer surface of the first guide component 34; or, as another alternative embodiment, the first guide component 34 is a non-circular component whose outer surface is partially arc-shaped, such as a plate or a semi-cylinder or other irregularly shaped body whose outer surface is partially arc-shaped, wherein the first annular belt 31 contacts the arc-shaped outer surface of the first guide component 34.

[0094] like Fig.18As shown, in one embodiment, the introduction member 30 includes two first guide members 34, and the two first guide members 34 form an introduction slope 30a at the position of the first endless belt 31 close to the surface to be cleaned 200. With this embodiment, the first endless belt 31 can have an introduction slope 30a of a certain length, so as to facilitate the introduction member 30 to better sweep in garbage of different volumes. Of course, the number of the first guide members 34 is not limited to two, and can also be more than two, which can be determined according to actual design needs. When the number of the first guide members 34 is more than two, two of the first guide members 34 form an introduction slope 30a at the position of the first endless belt 31 close to the surface to be cleaned 200.

[0095] It should be noted that the present invention is not limited to the above-mentioned embodiment. For example, in another embodiment, the first roller 33 and at least one first guide member 34 form an introduction slope 30 a at a portion of the first endless belt 31 close to the surface 200 to be cleaned.

[0096] It should be noted that the introduction slope 30a can be as follows Fig.18 The plane shown in FIG. 1 is formed by two first guide members 34 abutting against the first endless belt 31, or by the first roller 33 and at least one first guide member 34 abutting against the first endless belt 31. Of course, the introduction slope 30a is not limited to being a plane. For example, in another embodiment, as Figure 3 As shown, the introduction slope 30a can be an arcuate surface, as long as the introduction slope 30a extends from the end of the introduction member 30 close to the surface to be cleaned 200 in a direction gradually away from the main cleaning member 20 and the surface to be cleaned 200, it is conducive to the large volume of garbage to enter between the introduction slope 30a and the surface to be cleaned 200. The specific design can be determined according to actual design needs. Optionally, in the embodiment where the introduction slope 30a is an arcuate surface, the introduction slope 30a is formed by the first roller 33 abutting the first endless belt 31.

[0097] like Fig.18 As shown, in one embodiment, a garbage conveying channel is formed between the main cleaning component 20 and the introduction component 30, and the main cleaning component 20 cooperates with the introduction component 30 to convey garbage along the garbage conveying channel without wind driving.

[0098] like Fig.18As shown, in one embodiment, the main cleaning component 20 includes a second endless belt 21, a third roller 23 and at least one second guide member 24, the third roller 23 and at least one second guide member 24 are spaced apart along the height direction of the cleaning device 100, and the second endless belt 21 is rotatably wrapped around the third roller 23 and the second guide member 24 to clean the surface to be cleaned 200. The second endless belt 21 is formed with a first plane 20a for abutting against the surface to be cleaned 200 at the bottom of the main cleaning component 20. In this embodiment, by arranging the second annular belt 21 to form a first plane 20a for abutting against the surface to be cleaned 200 at the bottom of the main cleaning component 20, the contact between the second annular belt 21 and the surface to be cleaned 200 can be made into surface contact, thereby increasing the contact area between the second annular belt 21 and the surface to be cleaned 200, which is beneficial to improving the cleaning effect and efficiency of the second annular belt 21 in cleaning the surface to be cleaned 200. In particular, for more stubborn stains on the surface to be cleaned 200 (such as coffee stains), this embodiment can quickly wipe them clean, thereby achieving the purpose of significantly improving the cleaning effect and efficiency of the cleaning device 100 in cleaning the surface to be cleaned 200.

[0099] In one embodiment, the second roller 36 can rotate freely around its own central axis under the action of external force. The second roller 36 rotates under the drive of external force, thereby driving the second endless belt 21 to rotate.

[0100] In one embodiment, the second guide member 24 is at least one of a roller, a rod whose at least partial outer surface is cylindrical, or a non-circular member whose partial outer surface is arc-shaped.

[0101] In one embodiment, at least one second guide member 24 is a roller, which can rotate freely around its own central axis under the action of an external force. Its specific structure can refer to the first roller 33, and will not be described in detail here. Here, the second guide member 24 is a roller, so that the second guide member 24 can not only support, tension, and guide the second endless belt 21, but also reduce the resistance generated by the second guide member 24 to the second endless belt 21 during the rotation of the second endless belt 21, which is conducive to improving the smoothness of the rotation of the second endless belt 21. Of course, the arrangement of the second guide component 24 is not limited to this. For example, as an alternative embodiment, the second guide component 24 is a rod body whose at least partial outer surface is cylindrical, and the second annular belt 21 contacts the cylindrical outer surface of the second guide component 24; or, as another alternative embodiment, the second guide component 24 is a non-circular component whose partial outer surface is arc-shaped, such as a plate or a semi-cylinder or other irregularly shaped body whose partial outer surface is arc-shaped, wherein the second annular belt 21 contacts the arc-shaped outer surface of the second guide component 24.

[0102] like Fig.18As shown, in one embodiment, the number of the second guide members 24 is two, and the two first guide members 34 are arranged at intervals in the horizontal direction to form the first plane 20a at a local portion of the second endless belt 21. With this embodiment, the second endless belt 21 can have a first plane 20a of a certain area, so that the main cleaning component 20 can clean the surface to be cleaned 200 more efficiently. Of course, the number of the second guide members 24 is not limited to two, and can also be more than two, which can be determined according to actual design needs. When the number of the second guide members 24 is more than two, two of the second guide members 24 form the first plane 20a at the portion of the second endless belt 21 close to the surface to be cleaned 200.

[0103] It should be noted that the present invention is not limited to the above-mentioned embodiment. For example, in another embodiment, at least one second guide member 24 and a third roller 23 are arranged at intervals in the horizontal direction to form a part of the second endless belt 21 into the first plane 20a.

[0104] like Fig.19 and Fig. 20 As shown, in another embodiment, the main cleaning component 20 includes a first cleaning auxiliary component 25 and a rolling brush component 26. The first cleaning auxiliary component 25 is arranged behind the introduction component 30 along the forward direction of the cleaning device 100. The introduction component 30 includes a third side portion M3 facing the first cleaning auxiliary component 25.
