DETAILED DESCRIPTION

[0032] The following are preferred implementations of the present application. It should be noted that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.

[0033] Before introducing the technical solutions of the present application, the technical problems in the related technologies are introduced in detail.

[0034] The main floor cleaning solutions include vacuum cleaners and floor scrubbers, each with its own advantages and disadvantages. Vacuum cleaners require a high-power suction motor, which is accompanied by loud noise and cannot clean wet floors. Related-art floor scrubbers, an evolution of vacuum cleaners, also suffer from the drawbacks of high power and noise. Furthermore, most related-art floor scrubbers lack the ability to self-clean their cleaning media or cleaning heads, requiring manual cleaning or return to a dedicated base station for cleaning.

[0035] In the related art, when there is large garbage on the ground during cleaning, if a vacuum cleaner is used to remove the large garbage on the ground, it is difficult to clean the stubborn dirt on the ground because the vacuum cleaner does not have clean water to soften the ground; if a floor scrubber is used to remove the large garbage on the ground, although the floor scrubber can spray water to soften the stubborn dirt on the ground, it cannot self-clean its own cleaning medium (for example, a cleaning roller) from time to time, and needs to be manually taken out or returned to a specific base station for cleaning, which is troublesome, time-consuming and labor-intensive; if the sewage generated by the cleaning roller when cleaning the ground is mixed with the impurities on the ground and sucked out, it is easy to cause the pipes of the cleaning device to be blocked, thereby causing the cleaning device to be unable to effectively clean the impurities or stubborn dirt on the ground.

[0036] Please refer to Figure 1-Figure 3This embodiment provides a cleaning device 10, which includes a housing 11, a cleaning roller 12, a seal 13, and a dust collection system. The cleaning roller 12 is disposed within the housing 11 and is rotatable relative to the housing 11. The cleaning roller 12 is configured to abut against the surface 2 to be cleaned. The seal 13 is convexly disposed on the housing 11, and the end of the seal 13 facing away from the housing 11 is configured to abut against the surface 2 to be cleaned. The dust collection system has a dust collection port 141, which is disposed between the seal 13 and the cleaning roller 12.

[0037] In which, the side of the cleaning roller 12 facing away from the seal 13 forms a cleaning area 10a, and a suction area 10b is formed between the seal 13 and the cleaning roller 12. When the cleaning device 10 moves along the cleaning direction, the cleaning roller 12 is first used to transfer impurities located in the cleaning area 10a and placed on the surface to be cleaned 2 to the suction area 10b, and the dust collection system then removes the impurities located in the suction area 10b through the dust collection port 141.

[0038] The cleaning device 10 is a device and apparatus used for cleaning floors. It primarily comprises a housing 11, a cleaning roller 12, a seal 13, and a dust collection system. The housing 11 primarily houses and protects the various components of the cleaning device 10. The cleaning roller 12 is used to clean floor stains. At least a portion of the cleaning roller 12 is located within the housing 11 of the cleaning device 10 and is capable of rotating relative to the housing 11.

[0039] For example, the cleaning device 10 further includes a motor disposed within the housing 11. The cleaning roller 12 is rotatably connected to the motor, and the motor is used to drive the cleaning roller 12 to rotate. When the motor drives the cleaning roller 12 to operate, the cleaning roller 12 rotates relative to the housing 11, thereby allowing the cleaning roller 12 to clean the floor. During the cleaning process, the cleaning surface of the cleaning roller 12 and the surface to be cleaned 2 generate relative motion, thereby achieving the cleaning effect of the cleaning device 10 on the floor.

[0040] The seal 13 is flexible. The end of the seal 13 facing away from the surface to be cleaned 2 is connected to the housing 11. The connection between the seal 13 and the housing 11 can be a snap-fit connection, an adhesive connection, a threaded connection, etc., which is not limited in this embodiment. The end of the seal 13 facing the surface to be cleaned 2 is used to abut against the surface to be cleaned 2. The seal 13 is in close contact with the surface to be cleaned 2, forming a flexible seal. The seal 13 cooperates with the cleaning roller 12 abutting against the surface to be cleaned 2, forming a suction area 10b between the seal 13 and the cleaning roller 12, thereby reducing the instantaneous cross-section of the dust suction port 141.

[0041] The dust collection system is used to absorb and collect garbage from the surface to be cleaned 2. The dust collection system is provided in the cleaning device 10. The dust collection device has a dust collection port 141, which is provided on the housing 11 and faces the suction area 10b. The dust collection port 141 is located between the seal 13 and the cleaning roller 12, and is provided facing the dust collection area.

[0042] Specifically, when the cleaning device 10 moves along the cleaning direction, the cleaning direction is as follows: Figure 2 As shown in the middle direction D1, the cleaning device 10 moves horizontally on the surface to be cleaned 2. The cleaning roller 12 first sweeps at least a portion of the impurities in the cleaning area 10a to the suction area 10b. For example, the adhesion technology of the cleaning roller 12 sweeps the garbage on the ground from the cleaning area 10a to the suction area 10b. Then, the dust suction port 141 sucks the impurities in the suction area 10b, thereby separating the impurities from the wastewater generated by the cleaning roller 12 when cleaning the ground, avoiding blockage of the pipeline of the cleaning device 10, facilitating the removal of impurities, and enabling the cleaning device 10 to effectively clean ground impurities or stubborn dirt. The sealing member 13 and the cleaning roller 12 are in close contact with the surface to be cleaned 2 to form a flexible seal, reducing the instantaneous cross-section of the dust inlet. A relatively sealed suction area 10b is formed between the sealing member 13 and the cleaning roller 12. Under the condition of constant suction force, the dust collection system can use lower power to absorb impurities, reducing energy consumption of the cleaning device 10, reducing the noise of the cleaning device 10 during operation, and improving the user experience.

[0043] In addition, the dust collection system absorbs impurities and cooperates with the cleaning roller 12 to clean the surface to be cleaned 2, which can effectively clean ground impurities or stubborn dirt and improve the cleaning effect of the cleaning device 10.

[0044] Please refer to Figure 1-Figure 3 In one embodiment, the dust collection system includes a suction piece 142 and a storage chamber 143 provided in the shell 11. One side of the storage chamber 143 is connected to the dust collection port 141, and the other side is connected to the suction piece 142. The storage chamber 143 is used to store impurities sucked away from the suction area 10b.

[0045] The dust collection system further includes a partition 144 disposed in the storage cavity 143 . The partition 144 is disposed between the dust collection port 141 and the suction member 142 . The partition 144 is configured to allow the gas in the storage cavity 143 to flow in a preset direction.

[0046] The suction member 142 is disposed within the housing 11. The suction member 142 may be a suction tube, a suction pump, or the like. The suction pump may also be understood as a suction fan. For example, the suction member 142 may be a suction tube, one end of which is connected to the storage chamber 143, and the other end of which is connected to the suction pump. The suction pump extracts gas from the suction tube and the storage chamber 143, thereby drawing impurities from the suction area 10b into the storage chamber 143. For another example, the suction member 142 may be a suction pump, which is directly connected to the storage chamber 143. The suction pump extracts gas from the storage chamber 143, thereby drawing impurities from the suction area 10b into the storage chamber 143.

[0047] The shell 11 is provided with a storage chamber 143, and impurities can be temporarily stored in the storage chamber 143. Optionally, the storage chamber 143 is detachably connected to the shell 11 to facilitate cleaning of impurities in the storage chamber 143. The storage chamber 143 is connected to the dust suction port 141. In addition, a partition 144 is provided on the inner wall of the storage chamber 143, and there is at least one partition 144. The partition 144 can divide the storage chamber 143 into a plurality of interconnected sub-chambers, so that the gas in the storage chamber 143 flows along a preset direction when the suction member 142 sucks, and the sucked impurities move along the preset direction in the storage chamber 143, thereby improving the suction effect of the dust suction system. The flow direction of the gas is as follows: Figure 3 As shown in the direction D3.

[0048] Optionally, the partition 144 includes a first partition sub-member and a second partition sub-member, the first partition sub-member being disposed on the bottom cavity wall of the storage cavity 143, and the second partition sub-member being disposed on the top cavity wall of the storage cavity 143, with the first partition sub-member being closer to the dust suction port 141 than the second partition sub-member. By providing the first and second partition sub-members to divide the storage cavity 143 into an S-shaped, or nearly S-shaped, cavity, the probability of impurities falling back from the storage cavity 143 into the outside is reduced, thereby improving the suction effect of the dust collection system.

[0049] In summary, this embodiment provides a dust collection system consisting of a suction piece 142, a storage chamber 143, and a partition 144, which not only enables the dust collection port 141 to absorb impurities into the storage chamber 143, but also reduces the probability of impurities falling back from the storage chamber 143 to the outside, thereby improving the suction effect of the dust collection system.

[0050] Please refer to Figure 1-Figure 3 In one embodiment, the dust collection system further includes a filter element 145 disposed between the storage chamber 143 and the suction element 142, and the filter element 145 is used to block impurities disposed in the storage chamber 143 and to allow gas to flow.

[0051] Filter 145 is used to filter impurities, preventing larger debris from migrating to suction element 142 and preventing clogging of suction element 142. Filter 145 is disposed within housing 11 and may be a filter sponge, a filter screen, or the like. Filter 145 has multiple vents through which air can flow, allowing suction element 142 to draw air from storage chamber 143.

[0052] In summary, this embodiment can prevent impurities from clogging the suction member 142 by disposing the filter member 145 between the storage chamber 143 and the suction member 142, thereby improving the reliability of the dust collection system and thus improving the reliability of the cleaning device 10.

[0053] Please refer to Figure 1-Figure 3 In one embodiment, along the cleaning direction of the cleaning device 10 , the suction member 142 , the storage chamber 143 , and the cleaning roller 12 are arranged in sequence; and the sealing member 13 is provided corresponding to the storage chamber 143 .

[0054] The cleaning direction of the cleaning device 10 can also be understood as the moving direction of the cleaning device 10 relative to the surface 2 to be cleaned. Figure 2 As shown, the cleaning direction of the cleaning device 10 is Figure 2 In the horizontal direction of the cleaning device 10, the suction member 142, the storage chamber 143, and the cleaning roller 12 are sequentially arranged in the horizontal direction of the cleaning device 10, and can also be arranged in a three-dimensional manner along the space. In addition, the sealing member 13 and the storage chamber 143 are arranged correspondingly, that is, the sealing member 13 and the storage chamber 143 are arranged in the vertical direction of the cleaning device 10. It can also be understood that the suction member 142, the sealing member 13, and the cleaning roller 12 are sequentially arranged in the horizontal direction of the cleaning device 10, so that the suction area 10b and the cleaning area are sequentially arranged in the horizontal direction of the cleaning device 10, and the suction area 10b and the cleaning area are sequentially arranged in the cleaning direction of the cleaning device 10.

[0055] In summary, this embodiment limits the positions of the suction piece 142, the storage cavity 143, the cleaning roller 12, and the sealing piece 13, so that the cleaning device 10 forms a suction area 10b and a cleaning area arranged in sequence along the cleaning direction of the cleaning device 10, so that the cleaning roller 12 first transfers the impurities from the cleaning area 10a to the suction area 10b, and then sucks the impurities into the storage cavity 143 through the suction port, performing the operation of sweeping first and then sucking, thereby optimizing the structural layout and facilitating user use.

[0056] Please refer to Figure 1-Figure 3 In one embodiment, the sealing member 13 is a flexible member; and / or, along the arrangement direction from the shell 11 to the surface to be cleaned 2, the height of the sealing member 13 can be self-adjusted to adapt to the surface to be cleaned 2.

[0057] The seal 13 is a flexible member made of a flexible material. For example, the material of the seal 13 is rubber, plastic, or the like. By defining the seal 13 as a flexible member, this embodiment allows the seal 13 to better conform to the surface 2 to be cleaned, even on uneven surfaces 2 to be cleaned, thereby enhancing the sealing effect of the seal 13 on the surface 2 to be cleaned.

[0058] like Figure 3 As shown, the arrangement direction from the housing 11 to the surface to be cleaned 2 is as follows Figure 3 In the direction from top to bottom, the height of the seal 13 can be self-adjusted according to the ground conditions of the surface to be cleaned 2, thereby realizing the flexible sealing of the seal 13 on the surface to be cleaned 2, so as to improve the sealing effect of the seal 13 on the flexible sealing of the surface to be cleaned 2.

[0059] Alternatively, as Figure 3 As shown, the arrangement direction from the housing 11 to the surface to be cleaned 2 is as follows Figure 3 The width of the seal 13 gradually decreases from top to bottom. Alternatively, the seal 13 may be understood as being in the shape of an inverted trapezoid, or a quasi-inverted trapezoid. In other words, the width of the end of the seal 13 closest to the surface 2 to be cleaned is smaller than the width of the end of the seal 13 further from the surface 2 to be cleaned. By limiting the size of the seal 13 in this embodiment, the end of the seal 13 closest to the surface 2 to be cleaned is more easily bent, thereby better conforming the seal 13 to the surface 2 to be cleaned and improving the sealing effect of the seal 13 on the surface 2 to be cleaned.

[0060] Please refer to Figures 1-4 In one embodiment, the shell 11 corresponding to the suction area 10b is provided with a groove 111, and the groove 111 connects the suction area 10b with the outside world. Impurities outside the suction area 10b can enter the suction area 10b through the groove 111 and be removed.

[0061] The groove 111 extends through the sidewall of the housing 11, connecting the suction area 10b with the outside world. Alternatively, the sidewall of the housing 11 may be understood as having an opening connecting the suction area 10b with the outside world. This embodiment provides the housing 11 with the groove 111, allowing the user to remove impurities outside the suction area 10b through the groove 111, thereby improving the cleaning performance of the vacuum system and, consequently, the cleaning performance of the cleaning device 10.

[0062] Please refer to Figures 1-6 In one embodiment, the cleaning device 10 further includes an extrusion member 15 disposed in the shell 11, the extrusion member 15 abuts against the cleaning roller 12, and a receiving cavity 151 is provided on the side of the extrusion member 15 facing the cleaning roller 12, and the extrusion member 15 is used to squeeze the cleaning roller 12.

[0063] When the cleaning roller 12 cleans the surface to be cleaned 2 , sewage is disposed in the cleaning roller 12 . The extruding member 15 squeezes the cleaning roller 12 and allows the sewage to flow into the accommodating chamber 151 .

[0064] The extrusion member 15 is used to clean the cleaning roller 12. The extrusion member 15 is arranged inside the housing 11. The connection between the extrusion member 15 and the housing 11 can be a snap connection, an adhesive connection, a threaded connection, or a combination thereof, etc., which is not limited in this embodiment. The extrusion member 15 is arranged on one side of the cleaning roller 12, and one end of the extrusion member 15 presses against the cleaning roller 12 to squeeze the cleaning roller 12, and the sewage from the cleaning roller 12 is squeezed out by applying pressure to the surface of the cleaning roller 12. Among them, since the cleaning roller 12 is cleaning the surface to be cleaned, that is, in the process of cleaning the ground, the clean water in the cleaning roller 12 will be contaminated by impurities on the ground, and thus the clean water in the cleaning roller 12 is converted into sewage.

[0065] In addition, the extrusion member 15 is provided with a accommodating chamber 151, which is mainly used to collect sewage generated by the extrusion of the extrusion member 15 and store the sewage in the accommodating chamber 151 or transport the sewage through the accommodating chamber 151 to a sewage tank 163 connected to the extrusion member 15. The accommodating chamber 151 is surrounded by the extrusion member 15 and the cleaning roller 12. The contact surface between the extrusion member 15 and the cleaning roller 12 is a sealing surface. In other words, the extrusion member 15 and the cleaning roller 12 form a relatively sealed space, which can prevent sewage from flowing out from the contact surface between the extrusion member 15 and the cleaning roller 12.

[0066] In summary, this embodiment, by providing the extrusion member 15, enables the cleaning roller 12 to self-clean during operation, eliminating the need for manual removal of the cleaning roller 12 for cleaning, thereby reducing the cleaning cost of the cleaning device 10 and improving the user experience. Furthermore, because the cleaning roller 12 can maintain a relatively clean state with the cooperation of the extrusion member 15, the cleaning effect of the cleaning device 10 is further improved.

[0067] Please refer to Figures 1-6 In one embodiment, the extrusion member 15 includes a connecting portion 152, a first extrusion portion 153 and a second extrusion portion 154 provided on opposite sides of the connecting portion 152, the first extrusion portion 153, the connecting portion 152, the second extrusion portion 154, and the cleaning roller 12 surround the accommodating cavity 151, the first extrusion portion 153 and the second extrusion portion 154 support the cleaning roller 12, the first extrusion portion 153 is farther away from the sealing member 13 than the second extrusion portion 154, and the height of the first extrusion portion 153 is greater than the height of the second extrusion portion 154.

[0068] The first extrusion portion 153 and the second extrusion portion 154 are disposed opposite each other, and both extend toward the cleaning roller 12. The cross-sectional shape of the extrusion member 15 can be understood as a U-shape, a quasi-U-shape, etc. The ends of the first extrusion portion 153 and the second extrusion portion 154 away from the connecting portion 152 both abut against the cleaning roller 12.

[0069] Specifically, when the cleaning device 10 moves along the cleaning direction, the cleaning roller 12 rotates relative to the housing 11. The rotation direction of the cleaning roller 12 is as follows: Figure 2 As shown in the middle direction D2, the cleaning roller 12 moves along Figure 2 As the cleaning roller 12 rotates clockwise in the direction of rotation, the surface of the cleaning roller 12 passes through the second pressing portion 154 and the first pressing portion 153 in sequence. Furthermore, the height of the first pressing portion 153 is greater than the height of the second pressing portion 154. Therefore, the pressure exerted by the first pressing portion 153 on the cleaning roller 12 is greater than the pressure exerted by the second pressing portion 154 on the cleaning roller 12. This prevents the sewage from being retained outside the accommodating chamber 151, causing the sewage to flow freely on the surface of the cleaning roller 12 and thus preventing the sewage from being collected.

[0070] In summary, this embodiment forms a receiving chamber 151 for collecting sewage by the first extrusion portion 153, the connecting portion 152, the second extrusion portion 154, and the cleaning roller 12, and further improves the reliability of the cleaning device 10 by limiting the height of the first extrusion portion 153 to be greater than the height of the second extrusion portion 154, thereby preventing sewage from being disposed outside the receiving chamber 151.

[0071] Please refer to Figure 1-Figure 7 In one embodiment, the shell 11 has an outlet pipe 161 and an inlet pipe 162 arranged perpendicular to the extension direction of the extrusion member 15, the outlet pipe 161 is connected to one end of the accommodating chamber 151, and the inlet pipe 162 is connected to the other end of the accommodating chamber 151. The outlet pipe 161 is used to discharge the sewage, and the inlet pipe 162 is used to input clean water.

[0072] The water outlet pipe 161 and the water inlet pipe 162 are respectively disposed on opposite side walls of the housing 11. For example, a water outlet may be provided on a side wall or bottom wall of the accommodating chamber 151, and the water outlet may be connected to the water outlet pipe 161. For another example, a water inlet may be provided on a side wall or bottom wall of the accommodating chamber 151, and the water inlet may be connected to the water inlet pipe 162.

[0073] Optionally, the cleaning device 10 also includes a clean water tank 164 for storing clean water and a sewage tank 163 for storing sewage. One end of the water inlet pipe 162 is connected to the accommodating chamber 151, and the other end is connected to the clean water tank 164. The clean water in the clean water tank 164 can flow into the accommodating chamber 151 through the water inlet pipe 162, and then flow to the cleaning roller 12, so that the cleaning roller 12 can clean the surface 2 to be cleaned; one end of the water outlet pipe 161 is connected to the accommodating chamber 151, and the other end is connected to the sewage tank 163. The sewage in the accommodating chamber 151 can flow into the sewage tank 163 through the water outlet pipe 161. The user can remove the sewage generated by the cleaning roller 12 by cleaning the sewage tank 163. The operation is simple and convenient.

[0074] Specifically, the clean water in the clean water tank 164 is pumped by the water pump 165 to one end of the accommodating chamber 151 and the cleaning roller 12, and the cleaning roller 12 absorbs the clean water to clean the cleaning roller 12. The sewage generated by the cleaning roller 12 is squeezed into the accommodating chamber 151 by the extruder 15, and the cycle continues. Finally, the sewage from the cleaning roller 12 flows into the other end of the accommodating chamber 151, enters the water outlet pipe 161, and is then collected in the sewage tank 163, thereby achieving real-time self-cleaning of the cleaning roller 12. The flow direction of clean water and sewage is as follows: Figure 7 As shown in the direction D4.

[0075] In the cleaning device 10 provided in this embodiment, impurities enter the storage chamber 143 through the suction port 141, while sewage enters the accommodating chamber 151 and the water outlet pipe 161 in sequence, and then flows into the sewage tank 163, thereby achieving solid-liquid separation, making it easier for users to clean without clogging the pipe.

[0076] In summary, this embodiment achieves self-cleaning of the cleaning roller 12 by providing the water outlet pipe 161 and the water inlet pipe 162, thereby further reducing the cleaning cost of the cleaning device 10 and further improving the user experience. In addition, because the cleaning roller 12 can maintain a relatively clean state with the cooperation of the extrusion member 15, the cleaning effect of the cleaning device 10 is further improved.

[0077] Please refer to Figure 1-Figure 7 The present application also provides a cleaning machine 1 , which includes a device body 20 and a cleaning device 10 as provided above in the present application, wherein the cleaning device 10 is arranged on the device body 20 .

[0078] The cleaning machine 1 provided in this embodiment adopts the cleaning device 10 provided above in this application. When the cleaning device 10 cleans impurities, the cleaning roller 12 first sweeps at least part of the impurities located in the cleaning area 10a to the suction area 10b, and then the dust suction port 141 absorbs the impurities located in the suction area 10b, thereby separating the impurities from the sewage generated by the cleaning roller 12 when cleaning the ground, avoiding blockage of the pipeline of the cleaning device 10, facilitating the cleaning of impurities, and enabling the cleaning device 10 to effectively clean ground impurities or stubborn dirt. In addition, a relatively sealed suction area 10b is formed between the seal 13 and the cleaning roller 12. The dust suction system can use lower power to absorb impurities, reduce the energy loss of the cleaning device 10, reduce the noise of the cleaning device 10 during operation, and improve the user experience.

[0079] In addition, the dust collection system absorbs impurities and cooperates with the cleaning roller 12 to clean the surface to be cleaned 2, which can effectively clean ground impurities or stubborn dirt and improve the cleaning effect of the cleaning device 10.
