[0006] In some embodiments, the water box is provided with a water storage cavity. The end of the sewage suction pipe is located in the water storage cavity, and the sewage detection component is located above the water storage cavity.

[0007] In the above cleaning device, the end of the sewage suction pipe will be submerged in the collected sewage in the water storage cavity, and the rest is above the sewage, so that the sewage cannot splash onto the upper part of the sewage suction pipe to prevent sewage from adhering to the wall of the sewage suction pipe; at the same time, the sewage in the water storage cavity will not splash onto the sewage detection component and affect the work of the sewage detection component.

[0008] In some embodiments, the cleaning device includes a bracket. The sewage suction pipe includes a first part and a second part connected to each other. A part of the first part is located in the water box, the second part is arranged on the top of the bracket, and the sewage detection component is connected to the second part.

[0009] In the above-mentioned cleaning device, a part of the first part extends into the sewage collected in the water box, and the sewage can be pumped to flow through the second part to the sewage detection component, so that the sewage detection component can detect the dirt of the sewage.

[0010] In some embodiments, the second part penetrates through the sewage detection component, and a joint is provided at one end of the second part away from the sewage detection component, and the joint is used to connect to the sewage tank.

[0017] In the above-mentioned cleaning device, there is a sliding stroke space for the sewage suction pipe on the groove, which can make the sewage flow to the groove more easily for convergence, facilitating the sewage suction pipe to pump dry the sewage. At the same time, the length of the groove is related to the moving stroke of the water box. The length of the groove ensures that during the movement of the water box, at the starting point or the end point of the moving stroke, the sewage suction pipe will not abut against the side wall of the groove, so the sewage suction pipe will not hinder the movement of the water box.

Therefore, the wetting effect of the ground remains consistent to a certain extent during the process of cleaning the ground, thereby ensuring the cleaning effect.

[0024] In some embodiments, the plurality of water outlet holes are evenly arranged along the length direction of the cleaning device.

[0062] Please refer to Figures 1 to 6 , a cleaning device 100 provided by the present utility model includes a water box 13, a light-transmitting sewage suction pipe 16, and a sewage detection assembly 10. One end 29 of the sewage suction pipe 16 is located inside the water box 13, and the sewage detection assembly 10 is provided at a position on the sewage suction pipe 16 away from the end 29. The sewage detection assembly 10 is configured to emit light to the sewage suction pipe 16 and receive the light transmitted or reflected by the sewage suction pipe 16.

[0063] In the above-mentioned cleaning device 100, since the sewage detection component 10 can emit light to the sewage suction pipe 16 and receive the light reflected by the sewage suction pipe 16, the sewage detection component 10 can be used to identify the degree of sewage contamination. After the sewage is scraped into the water box 13, it will be immediately sucked away by the sewage suction pipe. The sewage detection component 10 is arranged on the sewage suction pipe 16 to detect the degree of contamination. Therefore, the degree of sewage contamination can be identified earlier, the cleanliness of the cleaning part 63 and the floor cleaning can be judged in time, the water supply of the cleaning device 200 can be adjusted, the cleaning effect of the contaminated area can be enhanced, and real-time detection of sewage and repeated mopping can be achieved.

[0064] Specifically, the cleaning device 100 can be used for the cleaning device 200, and the cleaning device 200 includes, but is not limited to, a floor sweeper, a floor washer, a vacuum cleaner, a high-pressure cleaner, etc. The cleaning device 200 includes a body 150 and a cleaning device 100. The cleaning device 100 can be a mopping device. Optionally, please combine Figure 5 , the cleaning device 100 may include a cleaning component 60, and the cleaning component 60 includes a cleaning part 63 and a rotating shaft 66. In Figure 1 , the cleaning device 100 is installed at the rear side of the bottom of the body 150 and has a mopping function. Optionally, the cleaning part 63 can be a mop or a rag. When mopping the floor, the cleaning device 200 injects clean water onto the cleaning part 63. The cleaning part 63 is sleeved outside the rotating shaft 66. Driven by the rotating shaft 66, the cleaning part 63 rotates to clean the floor; a water scraping part 54 is arranged on the outer wall of the water box 13, and the water scraping part 54 presses against the cleaning part 63 to scrape the sewage carried on the cleaning part 63 into the water box 13. The water box 13 is used to collect the sewage on the cleaning part 63, and then the sewage suction pipe 16 pumps the sewage in the water box 13 to the sewage tank through a water pump.

[0065] Optionally, in the embodiment of the present utility model, the sewage detection component 10 adopts a reflection working principle, and the transceiver is integrated, and it can be realized without opening holes on both sides of the sewage suction pipe 16. The sewage detection component 10 is arranged on the cleaning device 100. The sewage detection component 10 may include a light emitter and a light receiver. The light emitter and the light receiver can be arranged outside the sewage suction pipe 16, and the light emitter can emit light (hereinafter referred to as detection light) to the sewage suction pipe 16. Since the sewage suction pipe 16 is light-transmitting, the detection light can pass through the sewage suction pipe 16 and enter the sewage suction pipe 16. The light receiver can receive the detection light transmitted or reflected by the sewage suction pipe 16 and output the corresponding light intensity. When sewage flows through the sewage suction pipe 16, the light intensity of the detection light reflected by the sewage suction pipe 16 will change. Therefore, the degree of contamination of the water in the sewage suction pipe 16 is detected by the light intensity of the detection light reflected by the sewage suction pipe 16, so that the cleanliness of the cleaning part 63 and the floor can be judged. It can be understood that the light intensity threshold corresponding to the detection of the degree of sewage contamination can be calibrated in advance and stored in the cleaning device 200. Different light intensity thresholds correspond to different degrees of contamination.

[0066] Optionally, the light emitter may include an LED light source. The light of the LED light source may be various visible lights such as green, red, yellow, white, etc., or light in other spectral bands (such as infrared light). The light receiver may include a photosensitive element for receiving the detection light reflected back by the sewage suction pipe 16, and then amplifying and processing the reflected detection light signal through a processing circuit. Different degrees of dirtiness of the sewage result in different reflection characteristics of the detection light. Due to the presence of suspended particles, grease, impurities and other suspended substances in the sewage, the more suspended substances there are, the stronger the intensity of the reflected detection light, thus reflecting a higher turbidity of the sewage, that is, a more serious degree of dirtiness. Then, it is judged whether to re-drag the area according to the degree of dirtiness, and the water supply of the cleaning device 200 is adjusted, which can, to a certain extent, enhance the cleaning effect of the dirty area.

[0067] In the related art, currently, the floor sweeper integrates the functions of sweeping and mopping. After mopping the floor, the floor sweeper returns to the base station to clean the mop. Base stations on the market usually are equipped with a sewage detection component, which is used to judge whether the mop and the ground are cleaned by the dirtiness of the sewage after cleaning when the main machine returns to the base station. This kind of base station identifies the dirtiness of the mop and the ground relatively late, cannot timely detect the dirtiness of the mop and the ground during the working process, cannot accurately find out which small area needs to be re-dragged, and is even less able to adjust the water supply of the mop of the floor sweeper according to the degree of dirtiness and perform strong mopping and floor washing at a fixed point.

[0068] In the embodiment of the present utility model, one end portion 29 of the sewage suction pipe 16 is located in the water box 13, and the sewage detection component 10 is arranged at a position on the sewage suction pipe 16 far from the end portion 29, that is, the sewage detection component 10 will not contact the collected sewage. After the sewage is scraped into the water box 13, the sewage suction pipe 16 will immediately suck away the sewage, and the sewage detection component 10 is arranged on the sewage suction pipe 16 to detect the sewage. Therefore, the dirtiness of the sewage can be identified earlier, the cleanliness of the cleaning part 63 and the ground can be judged in time, the water supply of the cleaning device 200 can be adjusted, the cleaning effect of the dirty area can be enhanced, and real-time detection of dirtiness and re-dragging can be achieved.

[0069] In some embodiments, the water box 13 is provided with a water storage cavity 39, the end portion 29 of the sewage suction pipe 16 is located in the water storage cavity 39, and the sewage detection component 10 is located above the water storage cavity 39.

[0070] In this way, the end of the first part 28 of the sewage suction pipe 16 will be submerged in the collected sewage in the water storage cavity 39, and the rest is above the sewage, so that the sewage cannot splash onto the upper part of the sewage suction pipe 16 to prevent the sewage from adhering to the wall of the sewage suction pipe 16; at the same time, the sewage in the water storage cavity will not splash onto the sewage detection component and affect the operation of the sewage detection component.

[0071] Specifically, in Figure 4In this case, a water storage cavity 39 is provided in the water box 13, and water is stored in the water storage cavity 39. The end 29 of the sewage suction pipe 16 extends into the sewage collected in the water storage cavity 39, and the other part is located above the water storage cavity 39, that is, above the sewage, so that the sewage cannot splash onto the upper part of the sewage suction pipe 16, preventing the sewage from adhering to the wall of the sewage suction pipe 16. The sewage detection assembly 10 is provided on the sewage suction pipe 16 and is located above the water storage cavity 39. The sewage in the water storage cavity 39 will not splash onto the sewage detection assembly 10 and affect the sewage detection work of the sewage detection assembly 10.

[0072] In some embodiments, the cleaning device 100 includes a bracket 19. The sewage suction pipe 16 includes a first part 28 and a second part 31 that are connected to each other. A part of the first part 28 is located in the water box 13, the second part 31 is provided on the top of the bracket 19, and the sewage detection assembly 10 is connected to the second part 31.

[0073] In this way, a part of the first part 28 extends into the sewage collected in the water box 13, and the sewage can be pumped to flow through the second part 31 to reach the sewage detection assembly 10, and the sewage detection assembly 10 can detect the dirt of the sewage.

[0074] Specifically, please refer to Figure 4 , a first part 28 of the sewage suction pipe 16 passes through a second bracket 25 and extends into the water box 13 to collect sewage, and the second part 31 is located on the top of the first bracket 22. The sewage suction pipe 16 can pump sewage to flow through the second part 31 to reach the sewage detection assembly 10. The sewage detection assembly 10 is fixedly connected to the first bracket 22. When the cleaning device 200 performs corner cleaning, the water box 13 and the second bracket 25 can be telescoped out of the body 150 together, while the first bracket 22, the sewage suction pipe 16 and the sewage detection assembly 10 are fixed, and the telescopic movement of the water box 13 and the second bracket 25 will not interfere with the work of the sewage suction pipe 16 and the sewage detection assembly 10.

[0075] In some embodiments, the second part 31 passes through the sewage detection assembly 10, and a joint 33 is provided at one end of the second part 31 away from the sewage detection assembly 10, and the joint 33 is used to connect the sewage tank.

[0076] In this way, the sewage can be pumped to the sewage tank through the joint 33, and during the sewage pumping process, the sewage detection assembly 10 can detect the dirt of the sewage and timely judge the cleanliness of the cleaning member 63 and the floor cleaning.

[0077] Specifically, a part of the first portion 28 is located inside the water box 13 to pump the sewage collected inside the water box 13. The second portion 31 passes through the sewage detection assembly 10. The sewage flows from the first portion 28 to the second portion 31 and is sent to the sewage tank through the connector 33. The sewage detection assembly 10 detects the sewage flowing through the second portion 31. One end of the second portion 31 away from the sewage detection assembly 10 is provided with a connector 33, and the connector 33 is used to connect to the sewage tank. Optionally, the connector 33 and the sewage tank can be connected with a rubber tube. In the related art, the cleaning device needs to return to the base station to perform sewage detection. In the embodiment of the present utility model, when the sewage flows through the area between the sewage suction pipe 16 of the cleaning device 200 and the sewage tank, the sewage detection assembly 10 can perform earlier dirt detection on the sewage.

[0078] In some embodiments, the bracket 19 includes a first bracket 22 and a second bracket 25. The water box 13 is arranged on the second bracket 25, and the second bracket 25 is movably arranged on the first bracket 22. The sewage suction pipe 16 is connected to the first bracket 22.

[0079] In this way, the second bracket 25 can drive the water box 13 to move on the first bracket 22 along the moving direction of the second bracket 25, which can increase the cleaning range of the cleaning device 100, cooperate with the cleaning member 63 to clean the corners of the ground, and also enable the sewage suction pipe 16 to further pump dry the sewage in the water box 13 in cooperation with the movement of the water box 13, without affecting the dirt recognition of the sewage.

[0080] Specifically, please refer to Figures 3 to 5 , the moving direction of the second bracket 25 is the left - right direction. The cleaning device 100 includes a cleaning assembly 60, and the cleaning assembly 60 is installed on the second bracket 25 and partially located in the accommodation cavity 48. The second bracket 25 can drive the water box 13 and the cleaning assembly 60 to move on the first bracket 22 along the moving direction of the second bracket 25.

[0081] When the cleaning device 200 performs corner cleaning of the whole house, the cleaning assembly 60 can be extended out of the body 150 for corner cleaning. Thus, the second bracket 25 can drive the water box 13 and the cleaning assembly 60 to move on the first bracket 22 along the moving direction of the second bracket 25 and extend out of the body 150 (as shown in Figure 3 ) to increase the cleaning range and achieve the purpose of including but not limited to corner cleaning. The second bracket 25 can also drive the water box 13 and the cleaning assembly 60 to move on the first bracket 22 along the moving direction of the second bracket 25 and retract into the body 150 (as shown in Figure 1 and Figure 2 ).

[0082] Optionally, the water box 13 is detachably connected to the second bracket 25 to facilitate the user to detach the water box 13 to clean the sewage and install the water box 13 on the second bracket 25. The detachable connection methods include but are not limited to snap fasteners, bolts and the like.

[0083] Please refer to Figure 4 , the cleaning device 100 further includes a driving component 83. The driving component 83 is installed on the first bracket 22. The driving component 83 is configured to drive the second bracket 25 and the water box 13 to move on the first bracket 22 along the moving direction of the second bracket 25, so that the second bracket 25 and the water box 13 can be telescoped along with the movement of the cleaning component 60. During the working process of the cleaning component 60, it cooperates with the cleaning component 60 to clean the corners of the ground, and can also make the sewage suction pipe 16 cooperate with the movement of the water box 13 to further drain the sewage in the water box 13. In the embodiment of the present utility model, the driving component 83 adopts a driving method of a motor. It can be understood that in other embodiments, the driving component 83 can also adopt a hydraulic driving method or a cylinder driving method.

[0084] Optionally, the driving component 83 includes a driving member 86 and a transmission member 89. The driving member 86 includes but is not limited to a rotary motor, and the transmission member 89 includes but is not limited to a lead screw. After the driving member 86 is powered on, it performs a rotational motion, and the rotational force is transmitted to the nut fixed on the second bracket 25 through the lead screw. The nut moves along the axial direction of the lead screw, driving the second bracket 25 and the water box 13 to move on the first bracket 22 along the moving direction of the second bracket 25, so that the cleaning device 100 can perform a telescoping motion. In other embodiments, the driving member 86 can adopt a linear motor. The type of the motor of the driving component 83 can be specifically defined according to actual needs, and the present utility model does not make specific limitations on this.

[0085] In some embodiments, the second bracket 25 is provided with a through groove 36, and the sewage suction pipe 16 passes through the through groove 36. The through groove 36 extends along the moving direction of the second bracket 25, and the through groove 36 is used to define the moving stroke of the second bracket 25.

[0086] In this way, there is a sliding stroke space for the sewage suction pipe 16 on the through groove 36, and the length of the through groove 36 can define the moving stroke of the second bracket 25.

[0087] Specifically, the through slot 36 is provided on the second bracket 25. The sewage suction pipe 16 can pass through the through slot 36. The second part 31 of the sewage suction pipe 16 is located above the through slot 36. There is a sliding stroke space for the sewage suction pipe 16 on the through slot 36, and the part of the sewage suction pipe 16 passing through the through slot 36 can move within the through slot 36. The through slot 36 extends along the moving direction of the second bracket 25. The moving stroke of the second bracket 25 is related to the length of the through slot 36 along the moving direction of the second bracket 25, such that during the movement of the second bracket 25, at the starting point or the ending point of the moving stroke, the sewage suction pipe 16 will not contact the side wall of the through slot 36, so the sewage suction pipe 16 will not hinder the movement of the second bracket 25.

[0088] The length of the through slot 36 along the moving direction of the second bracket 25 can be specifically defined according to actual situations, and the present utility model does not make specific limitations thereto.

[0089] In some embodiments, a water storage cavity 39 is provided in the water box 13. An opening 42 is provided at the top of the water storage cavity 39. The sewage suction pipe 16 extends into the water storage cavity 39 through the opening 42. A groove 45 is provided at the bottom of the water storage cavity 39. The groove 45 extends along the moving direction of the second bracket 25. The end 29 of the sewage suction pipe 16 is located within the groove 45.

[0090] In this way, there is a sliding stroke space for the sewage suction pipe 16 on the groove 45, which can make the sewage flow more easily towards the groove 45 for convergence, facilitating the sewage suction pipe 16 to suck out the sewage completely. At the same time, the length of the groove 45 is related to the moving stroke of the water box 13. The length of the groove 45 ensures that during the movement of the water box 13, at the starting point or the ending point of the moving stroke, the sewage suction pipe 16 will not contact the side wall of the groove 45, so the sewage suction pipe 16 will not hinder the movement of the water box 13.

[0091] Specifically, when the cleaning device 200 performs cleaning of the corners of the whole house, the cleaning assembly 60 needs to be extended out of the body 150 for corner cleaning. During the cleaning process, the sewage suction pipe 16 is fixed, and the water box 13 moves in a telescopic manner together with the cleaning assembly 60. However, as the water box 13 extends out of the body 150 according to different cleaning distances, it is difficult for the sewage suction pipe 16 to suck out the sewage collected in the water storage cavity 39 of the water box 13 at any time.

[0092] Therefore, by providing a groove 45 at the bottom of the water storage cavity 39 and the end 29 of the sewage suction pipe 16 being located within the groove 45, when the water box 13 moves, the water box 13 can avoid the sewage suction pipe 16 through the groove 45, making the movement and sewage suction of the water box 13 not difficult.

[0093] The length of the groove 45 along the moving direction of the second bracket 25 can be specifically defined according to actual situations, and the present utility model does not make specific limitations thereto.

[0094] In some embodiments, the bracket 19 is provided with a receiving cavity 48. The water box 13 includes a first side wall 51 facing the receiving cavity 48. A water scraping portion 54 and a water inlet hole 57 are provided on the first side wall 51. The water scraping portion 54 extends into the receiving cavity 48, and the water inlet hole 57 is located above the water scraping portion 54 and communicates the receiving cavity 48 with the interior of the water box 13.

[0095] In this way, after the water scraping portion 54 scrapes off the sewage, most of the sewage will flow into the water box 13 through the water inlet hole 57. At the same time, a small part of the sewage will accumulate along the water scraping portion 54 into the water box 13, so that the water box 13 can collect most of the sewage to a certain extent, preventing the liquid from accumulating or splashing on the ground.

[0096] Specifically, the working process of the cleaning device 100 is generally as follows: The cleaning equipment 200 injects clean water onto the cleaning member 63. The cleaning member 63 is sleeved outside the rotating shaft 66. Driven by the rotating shaft 66, the cleaning member 63 rotates to clean the ground. The water scraping portion 54 extends into the receiving cavity 48, and the water scraping portion 54 that is pressed against the cleaning member 63 scrapes the sewage carried on the cleaning member 63 into the water box 13, and then the sewage suction pipe 16 sucks the sewage in the water box 13 into the sewage tank.

[0097] The water scraping portion 54 is one of the important components of the cleaning device 100. The water scraping portion 54 can squeeze out the sewage carried on the cleaning member 63, and then the sewage flows into the water box 13 through the water inlet hole 57. Optionally, the water scraping portion can be strip-shaped. In the embodiments of the present utility model, please refer to Figure 5 , the shape of the end of the water scraping portion 54 is serrated to scrape off more sewage. It can be understood that in other embodiments, the shape of the end of the water scraping portion 54 is not limited to serrated, and can also be linear or other shapes.

[0098] The present utility model does not specifically limit the material of the water scraping portion 54. In one example, the material of the water scraping portion 54 can be silicone, rubber, polyurethane, plastic and other materials. Optionally, the water scraping portion 54 and the water box 13 are connected as an integral structure.

[0099] Optionally, the water inlet hole 57 penetrates the first side wall 51 along the upper surface of the water scraping portion 54. The sewage squeezed out by the water scraping portion 54 and the cleaning member 63 can flow directly into the water inlet hole 57 along the upper surface of the water scraping portion 54, so that the sewage can be collected into the water box 13 in time.

[0100] In Figure 5Among them, the cleaning component 60 is a crawler-type cleaning component 60. The part of the cleaning member 63 in contact with the first side wall 51 is arc-shaped, and the first side wall 51 is arc-shaped and adapted to the part in contact with the cleaning member 63. Thus, the fit between the two is relatively high, and the resistance during the rotation of the cleaning member 60 can be reduced. It can be understood that in other embodiments, the cleaning component 60 can also be a rotary cleaning component 60 or a drum-type cleaning component 60.

[0101] Optionally, in Figure 5 Among them, when the cleaning member 63 is performing normal cleaning work, the rotation direction is clockwise. The wiper part 54 in contact with the cleaning member 63 is fixed on the first side wall 51. Through mechanical pressure, the wiper part 54 applies a certain pressure to the cleaning member 63, so that the cleaning member 63 and the wiper part 54 squeeze out sewage from each other. On the one hand, most of the sewage will flow into the water box 13 through the water inlet hole 57; on the other hand, the wiper part 54 will guide a small part of the sewage to accumulate in the water box 13. In this way, the water box 13 can collect most of the sewage to a certain extent, which is convenient for the sewage suction pipe 16 to suck out the sewage completely and prevent the sewage from accumulating or splashing on the ground.

[0102] Optionally, in Figure 7 Among them, the moving direction of the second bracket 25 is the left-right direction. Along the moving direction of the second bracket 25, the wiper part 54 is inclined from the two side edges of the water box 13 to the middle bottom. When the wiper part 54 scrapes off the sewage, on the one hand, most of the sewage will flow into the water box 13 through the water inlet hole 57, and a small part of the sewage will flow along the wiper part 54 to accumulate in the middle of the water box 13, and the accumulated sewage will flow into the water box 13 through the water inlet hole 57 in the middle of the water box 13. Even if there is residual sewage that does not flow into the water box 13, this residual sewage will accumulate at the position of the wiper part 54 close to the middle of the water box 13. When the cleaning device 100 or the water box 13 is tilted, the sewage (hereinafter referred to as accumulated water) at the position of the wiper part 54 close to the middle of the water box 13 needs to flow through a longer path to reach the edge of the water box 13. During the flowing process, the accumulated water will adhere to the wiper part 54 on the flowing path and will be discharged into the water box 13 through the water inlet hole 57 on the flowing path, so that the amount of accumulated water is continuously decreasing. It is possible that the accumulated water disappears before reaching the edge of the water box 13. Even if the accumulated water can flow to the edge of the water box 13, the amount of accumulated water will become relatively small. Moreover, the sewage accumulated at the position of the wiper part 54 close to the middle of the water box 13 can also be sucked away by the cleaning member 63.

[0103] The sewage at the position of the wiper part 54 close to the middle of the water box 13 needs a longer time to flow out of the edge of the water box 13 due to the longer flowing path. In this way, it is possible to allow the cleaning device 100 or the water box 13 to be tilted for a short time without the accumulated water leaking out. To sum up, the problem of water leakage when the water box 13 is tilted can be improved to a certain extent, and the user experience can be enhanced.

[0104] In some embodiments, the cleaning device 100 includes a cleaning assembly 60 and a drip prevention portion 69. The cleaning assembly 60 is disposed in the accommodation cavity 48, and the drip prevention portion 69 extends into the accommodation cavity 48 from the first side wall 51. The cleaning assembly 60 includes a cleaning member 63, and the cleaning member 63 is connected to the wiper portion 54 and the drip prevention portion 69 in an interference fit manner. The drip prevention portion 69 is located below the wiper portion 54.

[0105] In this way, the sewage scraped off by the wiper portion 54 can drip onto the drip prevention portion 69, and the sewage can be blocked above the drip prevention portion 69 and carried away by the cleaning member 63, preventing the sewage from leaking out from the bottom of the cleaning device 100 to a certain extent.

[0106] Specifically, the interference fit connection between the wiper portion 54 and the cleaning member 63 means that the wiper portion 54 and the cleaning member 63 can be mutually extruded, facilitating the wiper portion 54 to scrape off the sewage carried on the cleaning member 63. Optionally, in one embodiment, the extrusion amount between the wiper portion 54 and the cleaning member 63 is less than the thickness of the cleaning member 63, making the rotational resistance of the cleaning assembly 60 small.

[0107] When the wiper portion 54 scrapes off sewage from the cleaning member 63, some sewage may flow along the edge of the wiper portion 54 to the lower part of the wiper portion 54 and leak out from the bottom of the cleaning device 100. By providing the drip prevention portion 69 and, in the rotational direction of the cleaning assembly 60, the drip prevention portion 69 is located below the wiper portion 54, so that the sewage flowing down from the wiper portion 54 can drip onto the drip prevention portion 69, and the sewage can be blocked above the drip prevention portion 69 and carried away by the cleaning member 63. Optionally, the drip prevention portion 69 can be strip-shaped.

[0108] Optionally, in Figure 5 ..., when the cleaning member 63 performs the cleaning work, the rotational direction is the clockwise direction. In the clockwise direction, the drip prevention portion 69 is located behind the wiper portion 54, so that after the wiper portion 54 wipes water, the drip prevention portion 69 can block the sewage on the drip prevention portion 69.

[0109] Optionally, the drip prevention portion 69 can be along the length direction of the cleaning device 100, and the length of the drip prevention portion 69 is substantially the same as the length of the wiper portion 54 along the moving direction of the second bracket 25, so that the sewage scraped off by the wiper portion 54 can be timely blocked above the drip prevention portion 69.

[0110] When the sewage scraped off by the wiper portion 54 flows to the drip prevention portion 69, the sewage can be blocked above the drip prevention portion 69, making it easier for the cleaning member 63 to carry away the sewage. The present utility model does not limit the material of the drip prevention portion 69. In one example, the material of the drip prevention portion 69 can be plastic, rubber, polyurethane or the like. Optionally, the drip prevention portion 69, the wiper portion 54 and the water box 13 can be connected into an integral structure.

[0111] In some embodiments, the cleaning device 100 includes a water dividing plate 72 and a cleaning assembly 60. At least a part of the cleaning assembly 60 is located in the accommodating cavity 48. The water dividing plate 72 is provided on the surface of the bracket 19 facing the accommodating cavity 48. The water dividing plate 72 is provided with a plurality of water outlet holes, and the water dividing plate 72 is configured to supply water to the cleaning assembly 60 through the plurality of water outlet holes to wet the cleaning assembly 60.

[0112] In this way, through the water dividing plate 72, the clean water is evenly distributed onto the cleaning member 63, and the wetting effect of the cleaning member 63 remains consistent to a certain extent. Therefore, the wetting effect on the ground remains consistent to a certain extent during the process of cleaning the ground, thus ensuring the cleaning effect.

[0113] Specifically, please refer to Figure 5 , the water dividing plate 72 is disposed in a recessed area on the surface of the second bracket 25 facing the accommodating cavity 48, and the shape profile of the recessed area closely fits the shape profile of the water dividing plate 72. The recessed area provides a stable support for the water dividing plate 72, ensuring the stability of the placement of the water dividing plate 72 to a certain extent and avoiding unnecessary shaking or movement. At the same time, it also achieves a concealed effect for the water dividing plate 72, making the water dividing plate 72 almost invisible and saving the placement space. The clean water is injected onto the cleaning assembly 60 through the water outlet holes on the water dividing plate 72 to wet the cleaning member 63, so that the cleaning member 63 can clean the ground.

[0114] The present utility model does not specifically limit the material of the water dividing plate 72. In one example, the material of the water dividing plate 72 can be stainless steel, aluminum alloy, high-density polyethylene or the like.

[0115] In some embodiments, the plurality of water outlet holes are uniformly arranged along the length direction of the cleaning device 100.

[0116] In this way, the clean water can be more evenly distributed onto the cleaning member 63.

[0117] Specifically, the length direction of the cleaning device 100 is the left-right direction. Optionally, in the embodiments of the present utility model, the plurality of water outlet holes being uniformly arranged along the length direction of the cleaning device 100 may mean that they are arranged in a row along the length direction of the water dividing plate 72, and the distance between adjacent two water outlet holes is equal.

[0118] In some embodiments, the cleaning device 100 includes a water equalizing strip 78 and a second bracket 25. The second bracket 25 is provided with an accommodating cavity 48. The water equalizing strip 78 protrudes on the surface of the bracket 19 facing the accommodating cavity 48. The cleaning assembly 60 includes a cleaning member 63. The water equalizing strip 78 is connected to the cleaning member 63 in an interference fit manner, and the water equalizing strip 78 is located below the water dividing plate 72.

[0119] Thus, when the water box 13 performs self-cleaning, the water poured by the water distribution plate 72 can quickly and evenly wet the cleaning member 63. Moreover, since the water equalizing strip 78 is connected to the cleaning assembly 60 in an interference fit, the effect of quickly and evenly wetting the cleaning member 63 can be effectively improved, and the time for self-cleaning can be saved.

[0120] Specifically, when the cleaning device 100 performs self-cleaning, clean water needs to be injected onto the cleaning member 63 through the water distribution plate 72 so that the cleaning member 63 can be evenly wetted. During the self-cleaning process of the cleaning device 100, it is difficult for the water poured by the water distribution plate 72 to quickly and evenly wet the cleaning member 63. Therefore, a water equalizing strip 78 is provided behind the water distribution plate 72 in the rotation direction of the cleaning member 63. Thus, during the self-cleaning process of the cleaning device 100, the water outlet holes on the water distribution plate 72 distribute clean water and inject it into the cleaning assembly 60, and the water equalizing strip 78 evenly wets the cleaning member 63 in cooperation with the rotation of the cleaning member 63, saving the time for self-cleaning to a certain extent. This can ensure that when the cleaning member 63 contacts the ground, the entire cleaning member 63 is covered with clean water, thereby avoiding the phenomenon that the area near the water outlet hole is overly wet while the area far from the water outlet hole remains dry. Optionally, in Figure 5 the rotation direction of the cleaning member 63 is the clockwise direction. Please refer to Figure 5 and the shape of the water equalizing strip 78 is strip-shaped. It can be understood that in other embodiments, the shape of the water equalizing strip 78 can be serrated.

[0121] The present utility model does not specifically limit the material of the water equalizing strip 78. In one example, the material of the water equalizing strip 78 can be rubber, polyurethane, rust-proof latex, or the like.

[0122] The interference fit connection between the water equalizing strip 78 and the cleaning assembly 60 means that the water equalizing strip 78 can be mutually extruded with the cleaning member 63, facilitating the water equalizing strip 78 to evenly wet the cleaning member 63 with clean water. Optionally, in one embodiment, the extrusion amount of the water equalizing strip 78 and the cleaning member 63 is less than the thickness of the cleaning member 63, so that the rotational resistance of the cleaning assembly 60 is small.

[0123] A cleaning device 200 in an embodiment of the present utility model includes the cleaning device 100 of any of the above embodiments.

[0124] In the above cleaning device 200, since the sewage detection assembly 10 can emit light to the sewage suction pipe 16 and receive the light reflected by the sewage suction pipe 16, the sewage detection assembly 10 can be used to identify the degree of sewage dirtiness, timely judge the cleaning degree of the cleaning member 63 and the ground, adjust the water supply amount of the cleaning device, strengthen the cleaning effect of the dirty area, and achieve real-time detection and repeated mopping of dirt.

[0125] Specifically, the cleaning device 200 includes, but is not limited to, a floor sweeper, a floor washer, a vacuum cleaner, a high-pressure cleaner, etc. Please refer to Figure 2and Figure 3 The cleaning device includes a body 150, a base 92, drive wheels 95, and a cleaning assembly 60. In one embodiment, the cleaning device 100 can be a mopping device. The base 92 is installed at the bottom of the body 150, and the cleaning device 100 is installed at the rear of the base 92 and has a mopping function. The cleaning member 63 of the cleaning assembly 60 can be a cleaning mop or a rag. When mopping the floor, the cleaning device 200 injects clean water onto the cleaning member 63 to moisten the cleaning member 63, so that the cleaning member 63 can clean the floor. The drive wheels 95 are installed on the base 92, and when the cleaning device 200 performs floor cleaning, they drive the cleaning device 200 to move on the floor.

[0126] In some embodiments, the cleaning device 200 includes a controller, a water injection pump, and a cleaning member 63. The controller is electrically connected to the sewage detection assembly 10 and the water injection pump;

[0127] The controller is configured to:

[0128] When the cleaning device 200 starts to work, control the water injection pump to inject water into the cleaning device 100 for a first water injection duration and control the cleaning member 63 to clean the floor;

[0129] When the light intensity output by the sewage detection assembly 10 is within a first set range, control the water injection pump to keep the first water injection duration unchanged and control the cleaning member 63 to continue cleaning the floor;

[0130] When the light intensity output by the sewage detection assembly 10 is within a second set range, control the water injection pump to inject water into the cleaning device for a second water injection duration and control the cleaning member 63 to continue cleaning the floor;

[0131] When the light intensity output by the sewage detection assembly 10 is within a third set range, control the water injection pump to inject water into the cleaning device 100 for a third water injection duration and control the cleaning member 63 to continue cleaning the floor;

[0132] Among them, the values of the first set range, the second set range, and the third set range are sorted in ascending order. The third water injection duration is greater than the second water injection duration, and the second water injection duration is greater than the first water injection duration.

[0133] In this way, the degree of sewage dirtiness can be identified earlier, and to a certain extent, real-time detection of dirtiness and repeated mopping can be achieved. Then, it is judged whether to perform repeated mopping cleaning according to the corresponding dirtiness level, and the water supply is adjusted to further enhance the cleaning effect of this area.

[0134] Specifically, when the cleaning device 200 is working, the cleaning device 200 injects clear water evenly into the cleaning member 63 through the water distribution plate 72 and the water equalizing strip 78 by means of a water injection pump, so that the cleaning member 63 is evenly wetted. The cleaning member 63 is sleeved outside the rotating shaft 66. Driven by the rotating shaft 66, the cleaning member 63 rotates and can clean the ground. The sewage detection component 10 is arranged between the sewage suction pipe 16 and the sewage tank. When sewage flows through this area, the sewage detection component 10 can detect the dirt of the sewage earlier. The sewage detection component 10 feeds back the detection result to the controller, so that the controller adjusts the water supply of the water injection pump according to the detection result.

[0135] Since sewage contains suspended particles, grease, impurities and other suspended substances, the more suspended substances there are, the stronger the light intensity of the detected light transmitted or reflected, thus reflecting that the turbidity of the sewage is higher, that is, the dirtier the degree. The light intensity of the detected light is represented by the magnitude of voltage or current. The dirt level of the sewage can be judged by setting one or more different light intensity thresholds. When setting one light intensity threshold, when the light intensity of the detected light is lower than the light intensity threshold, it means that the sewage is relatively clean, indicating that the ground is relatively clean. The water injection pump maintains the original clear water injection time and no re-cleaning is required; when the light intensity of the detected light is higher than the light intensity threshold, it means that the sewage is relatively turbid, indicating that the ground is relatively dirty and re-cleaning can be carried out. When setting multiple different light intensity thresholds, the multiple light intensity thresholds can define at least three threshold ranges, and the light intensity of the detected light is in different threshold ranges, so that the dirt level can be subdivided.

[0136] Optionally, two light intensity thresholds can define three threshold ranges. In one example, the two light intensity thresholds are set as T1 and T2 respectively. The first threshold T1 is less than the second threshold T2, that is, T1 < T2, and the magnitude of the detected light intensity is I. Sorted in ascending order of the light intensity values, they are divided into the first set range, the second set range and the third set range in turn: the first set range can be expressed as this range includes all light intensity values less than or equal to the first threshold T1, that is, I ≤ T1. When the light intensity of the detected light is in the first set range, the sewage is relatively clean; the second set range can be expressed as this range includes all light intensity values greater than the first threshold T1 and less than or equal to the second threshold T2, that is, T1 < I ≤ T2. When the light intensity of the detected light is in the second set range, the sewage is level-I dirty; the third set range can be expressed as this range includes all light intensities greater than the second threshold T2, that is, I > T2. When the light intensity of the detected light is in the third range, the sewage is level-II dirty. The numerical values of T1 and T2 can be specifically defined according to the actual situation, and the present utility model does not make specific limitations on this.

[0137] In one embodiment, when the cleaning device 200 starts to work, the time when the water injection pump starts to inject clean water is set as the first water injection duration, and the controller controls the water injection pump to inject water into the cleaning device 100 according to the first water injection duration and controls the cleaning member 63 to clean the ground.

[0138] Optionally, the mapping relationship between the setting range and the water injection duration can be pre-calibrated and stored in the cleaning device 200, and the first water injection duration, the second water injection duration, and the third water injection duration can be obtained through simulation, testing, and other methods.

[0139] In one embodiment, when the light intensity output by the sewage detection component 10 is within the first setting range, the sewage detection component 10 determines that it is clean water, indicating that the area being cleaned has reached the cleanliness level and does not need to be cleaned repeatedly. At this time, the water injection pump maintains the original water injection duration unchanged, and the controller controls the water injection pump to inject water into the cleaning device 100 according to the first water injection duration so that the cleaning member 63 is wetted to clean the ground.

[0140] In one embodiment, when the light intensity output by the sewage detection component 10 is within the second setting range, the sewage detection component 10 determines that the sewage is level-I dirty. The water injection pump needs to increase the time of injecting clean water, that is, the time when the water injection pump injects clean water at level-I dirty is set as the second water injection duration. Optionally, the second water injection duration is greater than the first water injection duration. When the sewage reaches the level-I dirty level, it indicates that the area being cleaned is relatively dirty and needs to be continuously cleaned. The controller controls the water injection pump to inject water into the cleaning device 100 with the second water injection duration, that is, increases the water supply volume so that the clean water wets the cleaning member 63.

[0141] In one embodiment, when the light intensity output by the sewage detection component 10 is within the third setting range, the sewage detection component 10 determines that the sewage is level-II dirty. The water injection pump needs to increase the time of injecting clean water, that is, the time when the water injection pump injects clean water at level-II dirty is set as the third water injection duration. Optionally, the third water injection duration is greater than the second water injection duration and the first water injection duration. When the sewage reaches the level-II dirty level, it indicates that the area being cleaned is relatively dirty and needs to be cleaned multiple times. The controller controls the water injection pump to inject water into the cleaning device 100 with the third water injection duration, that is, further increases the water supply volume so that the clean water wets the cleaning member 63.

[0142] Thus, the water injection pump can determine whether to adjust the water supply volume according to the dirty level of the sewage detected by the sewage detection component 10 and perform repeated mopping cleaning.

[0143] In some embodiments, the controller is configured to:

[0144] When the cleaning device 200 starts to work, record the cleaning start position;

[0145] Determine the cleaning end position according to the second water injection duration or the third water injection duration;

[0146] Determine the cleaning area according to the cleaning start position and the cleaning end position;

[0147] After the water injection pump finishes injecting water into the cleaning device 100 for the second water injection duration and the cleaning member 63 finishes one-time cleaning of the cleaning area, control the water injection pump to inject water into the cleaning device 100 again for the second water injection duration and control the cleaning member 63 to clean the cleaning area again until the light intensity output by the sewage detection component 10 is within the first set range;

[0148] After the water injection pump finishes injecting water into the cleaning device 100 for the third water injection duration and the cleaning member 63 finishes one-time cleaning of the cleaning area, control the water injection pump to inject water into the cleaning device 100 again for the third water injection duration and control the cleaning member 63 to clean the cleaning area again until the light intensity output by the sewage detection component 10 is within the first set range.

[0149] In this way, the relatively dirty area can be cleaned repeatedly in time, further enhancing the cleaning effect of this area.

[0150] Specifically, when the cleaning device 200 starts to work, the controller can record the cleaning start position. Optionally, the cleaning start position can be a specific position on the ground set by the user, or a position on the ground automatically determined by the cleaning device 200 according to a preset program or environmental recognition. The cleaning device 200 starts to work at the cleaning start position. The cleaning device 200 moves while cleaning, and its moving speed during cleaning can be determined. For example, in one embodiment, the moving speed of the cleaning device 200 during cleaning is constant.

[0151] The position reached by the cleaning device 200 after the second water injection duration or the third water injection duration can be used as the cleaning end position.

[0152] The cleaning start position and the cleaning end position respectively mark the starting boundary and the ending boundary of the cleaning area. The area covered by the cleaning member 63 at the cleaning start position, the area covered by the cleaning member 63 at the cleaning end position, and the area covered between the cleaning start position and the cleaning end position constitute the cleaning area. The length of the cleaning area is the product of the moving speed of the cleaning device 200 and the second water injection duration or the third water injection duration. The cleaning member 63 has a specific size. Optionally, the area of the cleaning area is the product of the width of the cleaning member 63 and the length of the cleaning area.

[0153] The cleaning device 200 starts cleaning from the cleaning start position and reaches the cleaning end position after a preset second water injection duration or third water injection duration, completing one cleaning cycle. After the cleaning device 200 reaches the cleaning end position, the controller combines the cleaning start position and the cleaning end position to obtain the cleaning area, and controls the cleaning device 200 to perform at least one additional cleaning (re-mopping) on this cleaning area to improve the cleaning effect.

[0154] During the cleaning process of the cleaning device 200 on the area to be cleaned, when the dirt level corresponding to the sewage detected by the sewage detection component 10 is level I dirt, it indicates that the area being cleaned is relatively dirty and needs re-mopping cleaning. The water injection pump injects water into the cleaning device 100 for a second water injection duration to wet the cleaning part 63, and the cleaning part 63 can clean the ground. After reaching the cleaning end position, the controller controls the water injection pump to inject water into the cleaning device 100 again for a second water injection duration to wet the cleaning part 63, so that the cleaning part 63 cleans the cleaning area again until the light intensity output by the sewage detection component 10 is within the first set range and one cleaning cycle is completed and then stops, that is, the cleaning area reaches a relatively clean level, which can strengthen the cleaning effect of this area to a certain extent.

[0155] When the dirt level corresponding to the sewage detected by the sewage detection component 10 is level II dirt, it indicates that the area being cleaned is relatively dirty and needs multiple re-mopping cleanings. The water injection pump injects water into the cleaning device 100 for a third water injection duration to wet the cleaning part 63, and the cleaning part 63 can clean the ground. After reaching the cleaning end position, the controller controls the water injection pump to inject water into the cleaning device 100 again for a third water injection duration to wet the cleaning part 63, so that the cleaning part 63 cleans the cleaning area again until the light intensity output by the sewage detection component 10 is within the first set range and one cleaning cycle is completed and then stops, that is, the cleaning area reaches a relatively clean level, further strengthening the cleaning effect of this area.

[0156] In summary, when the controller adjusts the water supply volume according to the dirt level determined by the sewage detection component 10, it can timely perform re-mopping cleaning on the relatively dirty area, making this area cleaner.

[0157] In summary, the cleaning device 200 of the present utility model has at least the following technical solutions:

[0158] (1) The sewage detection component 10 is arranged inside the cleaning device 200, between the sewage suction pipe 16 and the sewage tank, and can identify the dirt level of the sewage earliest, timely judge whether the ground is clean, and achieve real-time detection of dirt and re-mopping.

[0159] (2) The sewage detection component 10 adopts a reflection working principle, and the transceiver is integrated, which can be realized without opening holes in the container.

[0160] (3) Judge the cleanliness of the rag and the ground according to the degree of sewage contamination feedback by the sewage detection component 10, adjust the water supply amount of the rag, and enhance the cleaning effect of the contaminated area.

[0161] (4) Driven by the driving member 86, the second bracket 25 and the cleaning component 60 can extend outwards synchronously. There is a reserved extension stroke on the water box 13 and the second bracket 25. During the outward extension process, the sewage suction pipe 16 and the sewage detection component 10 are fixed on the first bracket 22. Thus, the sewage suction pipe 16 can always suck sewage, and the sewage detection component 10 can detect the degree of sewage contamination in real time. In this way, while cleaning the ground corners along the edge, the degree of contamination of the corner ground can be identified in real time.
