Description

Technical Field

[0001] The present invention relates to the technical field of intelligent household appliances, and particularly to a cleaning device and its base. Background Art

[0002] With the progress of technology and the development of society, cleaning devices for indoor floor cleaning (such as floor washers, vacuum cleaners, etc.) have gradually entered people's lives. Traditional cleaning devices generally include a body and a base. A rolling brush is provided on the body. When the cleaning device is in the cleaning state, the body is separated from the base, and the water-carrying rolling brush walks on the surface to be cleaned and performs a cleaning operation on the surface to be cleaned; when the cleaning device is in the drying state, the body is connected to the base, and the rolling brush is connected outside the base, and the base can perform a drying operation on the rolling brush. The traditional base cannot quickly dry the rolling brush, resulting in a low drying efficiency of the rolling brush. Summary of the Invention

[0003] Based on this, in view of the problem of the low drying rate of the rolling brush, it is necessary to provide a cleaning device and its base that can improve the drying efficiency of the rolling brush.

[0004] A base for performing a drying operation on a rolling brush, the base comprising:

[0005] A base body;

[0006] An air-drying component, connected to the base body; and

[0007] A heating element, connected to the base body;

[0008] When the base performs the drying operation, the air-drying component is used to provide an air-drying airflow to the rolling brush, and the heating element is used to provide heat energy to the rolling brush.

[0009] In one embodiment, the air-drying component provides an air-drying airflow to a first area of the rolling brush, and the heating element synchronously provides heat energy to a second area of the rolling brush;

[0010] Wherein, the first area and the second area overlap at most partially.

[0011] In one embodiment, the first area and the second area do not overlap at all.

[0012] In one embodiment, a receiving cavity is formed in the base body, and the heating element is located in the receiving cavity; the base body has a bearing surface facing away from the receiving cavity and for bearing the rolling brush;

[0013] When the base performs the drying operation, the rolling brush is borne on the bearing surface of the base body, and the heating element provides heat energy to the rolling brush through the base body.

[0014] In one embodiment, the air-drying component is configured to provide a hot air flow for air-drying to the roller brush.

[0015] In one embodiment, the air-drying component includes a heating element and an air-drying element. A drying channel for accommodating the heating element is formed in the seat body, and an air outlet hole communicating with the drying channel is formed in the seat body.

[0016] When the base performs the drying operation, the air-drying element is configured to drive the air-drying air flow to blow towards the roller brush through the drying channel and the air outlet hole in sequence. The heating element is located on the flow path of the air-drying air flow in the drying channel and is used for heating the air-drying air flow.

[0017] In one embodiment, a water-blocking component is further included and is configured to be connected to the seat body. The water-blocking component is configured to close the air outlet hole when the base does not perform the drying operation, and is configured to open the air outlet hole when the base performs the drying operation.

[0018] In one embodiment, the water-blocking component includes an elastic element and a water-blocking element. The water-blocking element is movably arranged on the seat body along a first direction, and the elastic element is deformably connected between the water-blocking element and the seat body along the first direction.

[0019] In one embodiment, the water-blocking component includes a driving element and a water-blocking element. The water-blocking element is movably arranged on the seat body along a first direction. The driving element is in transmission connection with the water-blocking element, and the driving element is configured to drive the water-blocking element to open the air outlet hole when the base performs the drying operation.

[0020] In one embodiment, the driving element includes a driving main body and a pushing block. The driving main body is arranged on the seat body. The pushing block is in transmission connection with the driving main body and moves relative to the seat body along a second direction intersecting with the first direction.

[0021] Wherein, during the process of the pushing block moving along the second direction, the water-blocking element descends relative to the seat body under the drive of the pushing block along the first direction, and the air outlet hole is opened.

[0022] In one embodiment, the pushing block has a first guiding surface facing the water-blocking element, and there is a height difference of the first guiding surface in the first direction. The water-blocking element rises and falls relative to the seat body under the drive of the first guiding surface along the first direction, and opens or closes the air outlet hole.

[0023] In one embodiment, the first guiding surface is an inclined surface that slopes downward along the descending direction of the water-blocking element.

[0024] In one embodiment, the water baffle has a second guiding surface that cooperates with the first guiding surface, and the second guiding surface is an inclined surface that fits the first guiding surface.

[0025] In one embodiment, the water baffle assembly further includes a reset member, which is deformably connected between the push block and the water baffle and is used to provide a reset force for resetting the push block.

[0026] A cleaning device includes a base as described in any one of the above embodiments.

[0027] In the above cleaning device and its roller brush, during the drying operation of the base, the air drying assembly can provide an air drying flow to the roller brush.

Further, the heating element provides heat energy to the roller brush, so as to further accelerate the evaporation of the water, and finally makes the roller brush have a higher drying efficiency.

[0042] Please refer to Figure 1 and Figure 2, this application provides a cleaning device 1, which can be a floor washer, a vacuum cleaner, etc. The cleaning device 1 includes a base 100 and a body 200. The body 200 includes a main body 210, a nozzle 230 and a roller brush 250. The nozzle 230 and the roller brush 250 are both connected to the main body 210. The nozzle 230 is used to spray water on the roller brush 250. When the cleaning device 1 is in the cleaning state, the body 200 is separated from the base 100, and the body 200 moves on the surface to be cleaned, so that the roller brush 250 connected to the main body 210 can perform a cleaning operation on the surface to be cleaned. When the cleaning device 1 is in the drying state, the body 200 is connected to the base 100, the roller brush 250 is connected outside the base 100, and the base 100 performs a drying operation on the roller brush 250. When the cleaning device 1 is in the self-cleaning state, the body 200 is connected to the base 100, the roller brush 250 is connected outside the base 100 and rotates relative to the base 100, and the nozzle 230 sprays water on the roller brush 250 to clean the roller brush 250.

[0043] Specifically, the base 100 includes a seat body 10, an air drying component and a heating element 23. The air drying component and the heating element 23 are both connected to the seat body 10. When the base 100 performs a drying operation, the roller brush 250 is placed on the base 100 and rotates relative to the base 100 around the central axis of the roller brush 250 itself. Both the air drying component and the heating element 23 work. The air drying component is used to provide an air drying flow to the roller brush 250, and the heating element 23 is used to provide heat energy to the roller brush 250 to heat the roller brush 250. Optionally, the heating element 23 can be other heating structures such as a heating film, a heating tube, a heating wire, etc. Preferably, the heating element 23 is a heating film.

[0044] By setting the air drying component and the heating element 23, the air drying component provides an air drying flow to the roller brush 250. The air drying flow can drive the air to flow and accelerate the evaporation of the water in the roller brush 250, so that the rapid drying of the roller brush 250 can be realized. Further, the heating element 23 provides heat energy to the roller brush 250 so that the roller brush 250 can quickly heat up, thereby further accelerating the evaporation of water, and finally enabling the roller brush 250 to have a higher drying efficiency. It is worth mentioning that to prevent the heating element 23 from burning out the roller brush 250 and the seat body 10 due to overheating, a controller can be set to be electrically connected to the heating element 23, and the controller controls the temperature of the heating element 23 within the range of 50° to 60°.

[0045] In addition, during the process of the base 100 performing a drying operation, since the roller brush 250 is rotating, the air drying component can provide an air drying flow to the roller brush 250 along the circumferential direction of the roller brush 250, and the heating element 23 can also provide heat energy to the roller brush 250 along the circumferential direction of the roller brush 250, so as to facilitate the overall drying of the roller brush 250.

[0046] Further, the air-drying component provides an air-drying airflow to the first area of the roller brush 250, and the heating element 23 synchronously provides heat energy to the second area of the roller brush 250; wherein, the first area and the second area overlap at most partially. That is to say, at the same time point, the areas where the air-drying component and the heating element 23 work on the roller brush 250 overlap at most partially. It can be understood that when the heating element 23 is in direct contact with the roller brush 250, the second area is the area on the roller brush 250 that can be in direct contact with the heating element 23. When the heating element 23 is in indirect contact with the roller brush 250, the second area is the area on the roller brush 250 that can be in indirect contact with the heating element 23. At the same time point, the first area and the second area are different, but at different time points, due to the rotation of the roller brush 250, the first area and the second area may be the same. Moreover, the first area and the second area are not fixed areas. As the roller brush 250 rotates, at any two adjacent time points, the first area corresponding to the previous unit time is different from the first area corresponding to the next unit time, and the second area corresponding to the previous time is different from the second area corresponding to the next unit time.

[0047] It can be understood that under the action of the air-drying component, the air convection speed increases, and some heat on the roller brush 250 is also easily carried away by the airflow. If at the same time point, the first area and the second area overlap, and some heat on the second area will be carried away by the airflow. Furthermore, the drying speed of the second area will also decrease accordingly. In this application, since the first area and the second area overlap at most partially, the air-drying component and the heating element 23 can act on different areas of the roller brush 250 at the same time point, so that less heat is lost on the roller brush 250. Furthermore, the first area and the second area can be dried under the action of the air-drying component and the heating element 23 respectively. Then, as the roller brush 250 rotates, the first area and the second area are interchanged, so that the roller brush 250 can be dried comprehensively.

[0048] Furthermore, the first area and the second area do not overlap at all. Therefore, when the base 100 performs the drying operation, the air-drying component and the heating element 23 can simultaneously dry the first area and the second area of the roller brush 250 that do not overlap at all. During the drying process, less heat is lost on the roller brush 250, so that the drying efficiency of the roller brush 250 can be further improved.

[0049] Specifically, a receiving cavity 113 is formed inside the seat body 10, and the heating element 23 is located inside the receiving cavity 113; the seat body 10 has a bearing surface 111 facing away from the receiving cavity 113 and used for bearing the roller brush 250; when the base 100 performs the drying operation, the roller brush 250 is borne on the bearing surface 111 of the seat body 10, and the heating element 23 provides heat energy to the roller brush 250 through the seat body 10. That is to say, the heating element 23 indirectly provides heat energy to the roller brush 250 through the seat body 10. By providing the receiving cavity 113, the heating element 23 can be hidden inside the seat body 10. On the one hand, it can prevent the heating element 23 from contacting external water vapor, resulting in short circuit and electric leakage of the heating element 23. On the other hand, it can also effectively improve the aesthetics of the base 100.

[0050] Of course, the installation method of the heating element 23 is not limited to the above one. In some other embodiments, the heating element 23 can also be fixedly arranged on the bearing surface 111 and contact the roller brush 250 when the base 100 performs the drying operation. That is to say, in this embodiment, the heating element 23 directly contacts the roller brush 250 and provides heat energy to the roller brush 250. Therefore, the heat energy provided by the heating element 23 can be quickly conducted to the roller brush 250 and the roller brush 250 can be dried.

[0051] Preferably, the bearing surface 111 on the seat body 10 has a concave surface area 112, and the concave arc of the concave surface area 112 matches the outer peripheral surface arc of the roller brush 250. The heating element 23 is laid on the inner wall of the seat body 10 facing away from the concave surface area 112 and is indirectly in contact with the roller brush 250. In this way, the indirect contact area between the roller brush 250 and the heating element 23 can be further increased.

[0052] Further, when the base 100 performs the drying operation, the projection of the roller brush 250 on the bearing surface 111 completely falls within the projection range of the heating element 23 on the bearing surface 111. Therefore, after the roller brush 250 rotates one week, the heating element 23 can be in full indirect contact with the outer peripheral surface of the roller brush 250, so as to realize the full drying of the roller brush 250.

[0053] Please also refer to Figure 3 and Figure 6 , further, the air drying assembly is configured to provide an air drying hot air flow to the roller brush 250. In this way, the drying speed of the roller brush 250 can be further accelerated, so that the roller brush 250 has a high drying efficiency. In addition, the air drying hot air flow can also disinfect and sterilize the roller brush 250, thereby improving the cleanliness of the roller brush 250.

[0054] Specifically, the air-drying component includes a heating element 214 and an air-drying element 212. A drying channel 115 for accommodating the heating element 214 is formed in the base 10, and an air outlet 114 communicating with the drying channel 115 is provided on the base 10. When the base 100 performs the drying operation, the air-drying element 212 is configured to drive the air-drying air flow to blow towards the roller brush 250 through the drying channel 115 and the air outlet 114 in sequence (the air-drying air flow flows along the Figure 1 path shown by the arrow a-b-c-d in the figure), and the heating element 214 is located on the flow path of the air-drying air flow in the drying channel 115 and is used to heat the air-drying air flow to form a hot air-drying flow.

[0055] Optionally, the heating element 214 can be a variable-temperature electric heating wire or a PTC constant-temperature heating device. Preferably, the heating element 214 is a PTC constant-temperature heating device. In this way, the stability of the heat during the heating process can be maintained, and the energy consumption can also be reduced. Specifically, when the heating element 214 is working, the temperature on the surface of the heating element 214 can be maintained at about 150°.

[0056] The base 10 includes a base main body 11 and an air duct forming body 13. A receiving cavity 113 is formed in the base main body 11, and the air duct forming body 13 is disposed in the receiving cavity 113 and jointly defines the drying channel 115 with the inner wall of the receiving cavity 113. The air-drying element 212 is disposed in the receiving cavity 113 and is located in the middle of the base main body 11, and the air-drying element 212 is used to supply the air-drying air flow to the drying channel 115. The heating element 214 is disposed in the air outlet section of the drying channel 115 and is located on the flow path of the air-drying air flow in the drying channel 115.

[0057] Specifically, the base main body 11 includes an upper base 117 and a lower base 118. The upper base 117 and the lower base 118 jointly enclose to form the receiving cavity 113, and the bearing surface 111 is formed on the surface of the upper base 117 facing away from the lower base 118. The drying channel 115 has an air inlet section and an air outlet section. The air-drying element 212 inputs the air-drying air flow into the air inlet section of the drying channel 115, and the heating element 214 is disposed in the air outlet section of the drying channel 115. When the air-drying component works, the air flow flows into the drying channel 115 from the air inlet section and flows out from the air outlet of the drying channel 115. In the traditional cleaning device 1, the air-drying element 212 and the roller brush 250 are respectively disposed at opposite ends of the base main body 11 along the length direction of the base 10 (such as Figure 1 the direction shown by the arrow M in the figure). In this way, the drying channel 115 needs to span the entire length of the base main body 11 so that the air flow can blow towards the roller brush 250. However, in the present application, since the air-drying element 212 is located in the middle of the base main body 11, the length of the drying channel 115 can be adaptively shortened. Furthermore, the air loss of the air-drying air flow during the process of flowing through the drying channel 115 is also smaller, so that the air-drying air flow can blow towards the roller brush 250 at a high speed, thereby effectively improving the drying efficiency of the roller brush 250.

[0058] Furthermore, since the heating element 214 is provided in the air outlet section of the drying channel 115 and is located on the flow path of the air drying flow, the air drying flow can directly blow onto the roller brush 250 after being heated in the air outlet section of the drying channel 115. Compared with the heating element 214 being provided in the air inlet section of the drying channel 115, or the heating element 214 being provided between the air drying member 212 and the drying channel 115, when the heating element 214 is provided on the air outlet section of the drying channel 115, the flow length of the heated air drying flow can be reduced. Furthermore, the heat loss of the air drying flow during the flowing process is reduced, so it still has a relatively high temperature when blowing onto the roller brush 250, thereby enabling rapid drying of the roller brush 250.

[0059] Please refer to Figure 5 simultaneously. Specifically, the air inlet section of the drying channel 115 includes a flow expansion section 1152. The air drying member 212 is provided in the accommodation cavity 113 and is located outside the drying channel 115. The air drying member 212 is configured to input the air drying flow into the flow expansion section 1152 of the drying channel 115. The air outlet of the air drying member 212 has a first air drying diameter in a first radial direction (the width direction of the base 10, such as Figure 2 the direction indicated by the arrow E in the figure), and the flow expansion section 1152 has a first flow expansion diameter in the first radial direction. The first air drying diameter is the same as the first flow expansion diameter of the air inlet of the flow expansion section 1152. Among them, the first flow expansion diameter of the flow expansion section 1152 gradually increases along the flow direction of the air drying flow.

[0060] Specifically, air outlet holes 114 are formed in the seat main body 11. The air outlet holes 114 are communicated with the drying channel 115. When the base 100 performs the drying operation, the air drying member 212 is started, and the air drying flow flows out through the flow expansion section 1152, the air outlet section of the drying channel 115, and the air outlet holes 114 in sequence. To ensure that the air drying flow ejected from the air outlet holes 114 can blow onto the roller brush 250 along the axial direction of the roller brush 250, generally, the first output diameter of the air outlet holes 114 in the first radial direction is set to be approximately the same as the length of the roller brush 250 (the length direction of the roller brush 250 is the width direction of the base 10). To reduce the space occupied by the air drying member 212, generally, the air drying member 212 is set to have a relatively small volume, and the first air drying diameter is smaller than the first output diameter of the air outlet holes 114. Therefore, it is necessary to set the first flow expansion diameter of the flow expansion section 1152 to gradually increase along the flow direction of the air drying flow to increase the flow width of the air drying flow, so that the flow width of the air drying flow blown out through the drying channel 115 can finally match the first output diameter of the air outlet holes 114.

[0061] Since the first air-drying aperture is the same as the first diffuser aperture of the air inlet of the diffuser section 1152, the air outlet of the air-drying member 212 can be preferably transitioned to the air inlet of the diffuser section 1152. Therefore, when the air-drying air flow flows from the air-drying member 212 to the diffuser section 1152, the generation of eddy currents can be reduced, thereby effectively reducing the air loss, so that the air flow flowing out from the air outlet hole 114 finally has a relatively high flow rate. The air-drying air flow with a relatively high flow rate can quickly and comprehensively dry the roller brush 250, so that the roller brush 250 has a better drying effect.

[0062] In addition, to reduce the generation of eddy currents, the air outlet section of the drying channel 115 has a first air outlet aperture in the first radial direction. In the flowing direction of the air-drying air flow in the drying channel 115, the first air outlet aperture of the air outlet section of the drying channel 115 remains unchanged and is equal to the first diffuser aperture of the air outlet of the diffuser section 1152. In addition, the first output aperture of the air outlet hole 114 can be set to be equal to the first air outlet aperture of the air outlet section of the drying channel 115 to reduce the generation of eddy currents.

[0063] It is worth mentioning that the air outlet hole 114 also has a second output aperture in a second radial direction intersecting with the first radial direction (such as Figure 1 the direction indicated by the arrow N in the figure, that is, the height direction of the base body 10), and the drying channel 115 has a drying aperture in the second radial direction, and the second output aperture is smaller than the drying aperture. Specifically, when the flow rate remains unchanged, the smaller the aperture, the greater the flow rate. Therefore, by setting the second output aperture to be smaller than the drying aperture, after the air flow flows into the air outlet hole 114 through the diffuser section 1152 and the air outlet section of the drying channel 115, the air flow can be accelerated in the air outlet hole 114, so that the air flow can be ejected at a high speed.

[0064] Furthermore, the air inlet section of the drying channel 115 further includes a straight section 1154, and the straight section 1154 is connected between the air outlet of the air-drying member 212 and the air inlet of the diffuser section 1152. The straight section 1154 has a first straight aperture in the first radial direction. In the flowing direction of the air-drying air flow in the drying channel 115, the first straight aperture of the straight section 1154 remains unchanged and is equal to the first diffuser aperture of the air inlet of the diffuser section 1152. The straight section 1154 is used to transition the air-drying assembly and the diffuser section 1152. Under the action of the air-drying member 212, the air-drying member 212 can flow into the diffuser section 1152 through the straight section 1154.

[0065] Furthermore, the air inlet section of the drying channel 115 further includes a transition section 1156. The transition section 1156 is connected between the air outlet of the flow expansion section 1152 and the air outlet section of the drying channel 115. The transition section 1156 has a first transition diameter in a first radial direction. In the flowing direction of the air drying flow in the drying channel 115, the first transition diameter of the transition section 1156 remains unchanged and is equal to the first flow expansion diameter of the air outlet of the flow expansion section 1152. The transition section 1156 is used to transition between the flow expansion section 1152 and the air outlet section of the drying channel 115. Under the action of the air drying member 212, the air drying flow can sequentially pass through the straight section 1154, the flow expansion section 1152, the transition section 1156, and the air outlet holes 114 and spray onto the roller brush 250.

[0066] Specifically, compared with the flow expansion section 1152, since the first straight diameter of the straight section 1154 and the first transition diameter of the transition section 1156 both remain unchanged, the air loss in the straight section 1154 and the transition section 1156 is smaller than that in the flow expansion section 1152. It can be seen therefrom that by providing the straight section 1154 and / or the transition section 1156, the air loss during the flowing process of the air drying flow in the drying channel 115 can be reduced, so that the base 100 has a better drying effect.

[0067] Please refer to Figure 4 specifically, the air duct forming body 13 includes a first wind blocking rib 131 and a second wind blocking rib 133. The first wind blocking rib 131 and the second wind blocking rib 133 are arranged at intervals and jointly define the air inlet section of the drying channel 115 with the inner bottom wall and the inner top wall of the seat main body 11. Specifically, the first wind blocking rib 131 and the second wind blocking rib 133 are arranged at intervals along the width direction of the seat body 10, and the inner bottom wall and the inner top wall of the seat main body 11 are arranged at intervals along the height direction of the seat body 10. The first wind blocking rib 131, the second wind blocking rib 133, the inner bottom wall and the inner top wall of the seat main body 11 jointly enclose to form the air inlet section of the drying channel 115. The first wind blocking rib 131 and the second wind blocking rib 133 have a blocking effect on the air drying flow. By providing the first wind blocking rib 131 and the second wind blocking rib 133, the air drying flow can be guided to flow aggregately along the air inlet section of the drying channel 115 under the guidance of the first wind blocking rib 131 and the second wind blocking rib 133, so as to prevent the air drying flow from diffusing everywhere in the receiving cavity 113.

[0068] Further, both the first wind deflector rib 131 and the second wind deflector rib 133 are in close contact with the inner bottom wall and the inner top wall of the seat main body 11. In this way, it is possible to prevent the air drying flow located in the air inlet section of the drying channel 115 from diffusing into the remaining space in the receiving cavity 113 through the gaps between the first wind deflector rib 131 and the inner bottom wall of the seat main body 11, and / or between the first wind deflector rib 131 and the inner top wall of the seat main body 11, and / or between the second wind deflector rib 133 and the inner bottom wall of the seat main body 11, and / or between the second wind deflector rib 133 and the inner top wall of the seat main body 11. Furthermore, the air drying flow has a high degree of aggregation, so that the air drying flow can quickly dry the roller brush 250.

[0069] Optionally, the first wind deflector rib 131 can be in close contact with the inner bottom wall of the seat main body 11 and the inner top wall of the seat body 10 respectively by means of an elastic seal, or integral molding, or welding. Similarly, the second wind deflector rib 133 can also be in close contact with the inner bottom wall of the seat main body 11 and the inner top wall of the seat main body 11 respectively by means of an elastic seal, or integral molding, or welding.

[0070] Furthermore, the first wind deflector rib 131 includes a first straight portion 1312, a first flow expansion portion 1314, and a first transition portion 1316 that are sequentially arranged and connected along the flowing direction of the air drying flow in the drying channel 115, and the second wind deflector rib 133 includes a second straight portion 1332, a second flow expansion portion 1334, and a second transition portion 1336 that are sequentially arranged and connected along the flowing direction of the air drying flow in the drying channel 115. The first straight portion 1312 and the second straight portion 1332 are arranged at intervals in the width direction of the seat body 10, and together with the inner bottom wall and the inner top wall of the seat main body 11, they define a straight section 1154. The first flow expansion portion 1314 and the second flow expansion portion 1334 are arranged at intervals in the width direction of the seat body 10, and together with the inner bottom wall and the inner top wall of the seat main body 11, they define a flow expansion section 1152. The first transition portion 1316 and the second transition portion 1336 are arranged at intervals in the width direction of the seat body 10, and together with the inner bottom wall and the inner top wall of the seat main body 11, they define a transition section 1156.

[0071] In the air flow direction within the drying channel 115, the distance between the first straight portion 1312 and the second straight portion 1332, and the distance between the first transition portion 1316 and the second transition portion 1336 remain unchanged, while the distance between the first diffuser portion 1314 and the second diffuser portion 1334 gradually increases. It can be understood that the distance value between the first straight portion 1312 and the second straight portion 1332 is the first straight aperture of the straight section 1154, the distance value between the first transition portion 1316 and the second transition portion 1336 is the first transition aperture of the transition section 1156, the distance value between the connection of the first diffuser portion 1314 and the first straight portion 1312 and the connection of the second diffuser portion 1334 and the second straight portion 1332 is the first diffuser aperture of the air inlet of the diffuser section 1152, and the distance value between the connection of the first diffuser portion 1314 and the first transition portion 1316 and the connection of the second diffuser portion 1334 and the second transition portion 1336 is the first diffuser aperture of the air outlet of the diffuser section 1152.

[0072] Furthermore, the included angle between the first diffuser portion 1314 and the second diffuser portion 1334 is in the range of 130° to 150°. Specifically, if the included angle between the first diffuser portion 1314 and the second diffuser portion 1334 is too large, most of the air-drying airflow will only flow in the middle area of the diffuser section 1152, and the remaining part of the air-drying airflow will flow back from the gaps between the most of the air-drying airflow and the first diffuser portion 1314 and between the most of the air-drying airflow and the second diffuser portion 1334. In this way, the air-drying airflow flowing out from the air outlet holes 114 will decrease, and the drying efficiency of the roller brush 250 will also decrease accordingly. If the included angle between the first diffuser portion 1314 and the second diffuser portion 1334 is too small, to ensure that the first diffuser aperture of the air outlet of the diffuser section 1152 can match the first output aperture of the air outlet holes 114, the lengths of the first diffuser portion 1314 and the second diffuser portion 1334 should be increased adaptively. In this way, the length of the diffuser section 1152 will increase. Correspondingly, the length of the air inlet section of the drying channel 115 will also increase, and further, the wind loss will increase. In this way, the velocity of the air-drying airflow flowing out from the air outlet holes 114 is small, which is also not conducive to drying the roller brush 250. In the present application, since the included angle between the first diffuser portion 1314 and the second diffuser portion 1334 is in the range of 130° to 150°, the wind loss can be reduced on the premise of making the length of the diffuser section 1152 appropriate.

[0073] Furthermore, the ratio of the length of the diffuser section 1152 to the first diffuser aperture of the air outlet of the diffuser section 1152 is in the range of 0.7 to 0.9. At this ratio, the length of the diffuser section 1152 is appropriate and the first diffuser aperture of the air outlet of the diffuser section 1152 can match the first output aperture of the air outlet holes 114, thus having a smaller wind loss.

[0074] Please refer to again Figure 1 , and at the same time refer to Figure 6 , the air duct forming body 13 further includes a heating cover 135, the heating cover 135 has a heating cavity 1351, an input port 1352 and an output port 1353 are formed on the heating cover 135, and the input port 1352, the heating cavity 1351 and the output port 1353 are sequentially communicated to form the air outlet section of the drying channel 115, and the heating element 214 is arranged in the heating cavity 1351. Specifically, when the base 100 performs the drying operation, the air-drying air flow flows into the heating cover 135 from the air inlet section of the drying channel 115 through the input port 1352 and is ejected through the air outlet holes 114. By arranging the heating cover 135, the air-drying air flow can be gathered in the heating cover 135 and heated under the action of the heating element 214, so that the heat can be prevented from diffusing to other space parts in the accommodation cavity 113, and thus has a high heating efficiency.

[0075] Specifically, the heating cover 135 includes a cover body 1354 and a cover 1355, an installation port is formed on the cover body 1354, and both the input port 1352 and the output port 1353 are installed on the side walls of the cover body 1354 different from the installation port. The cover 1355 is detachably covered at the installation port and jointly defines the heating cavity 1351 with the cover body 1354. By disassembling the cover 1355, the heating element 214 can be conveniently loaded and unloaded from the installation port. Optionally, both the cover body 1354 and the cover 1355 can be made of high-temperature resistant PBT (polybutylene terephthalate) material.

[0076] Furthermore, the heating element 214 is arranged in the heating cavity 1351, and the projection of the heating element 214 in the plane where the input port 1352 is located completely covers the input port 1352. Therefore, it can be ensured that the air-drying air flow flowing in from the input port 1352 can flow through the heating element 214 and be heated.

[0077] Furthermore, the input port 1352 and the output port 1353 are arranged on the same side wall of the heating cover 135, and both the input port 1352 and the heating element 214 are located below the output port 1353. Then, in the process of the air-drying air flow flowing out from the output port 1353, the heating element 214 does not block the air-drying air flow, so that the air outlet holes 114 have a large air output.

[0078] Please refer to again at the same time Figure 3 , Figure 4 and Figure 5, the base 100 further includes a water blocking component 30 coupled to the base body 10. The water blocking component 30 is configured to close the air outlet hole 114 when the base 100 does not perform the drying operation, so as to prevent external water vapor, debris, etc. from entering the drying channel 115 and causing failures of the drying component. The water blocking component 30 is also used to open the air outlet hole 114 when the base 100 performs the drying operation, so that the air drying flow can be sprayed toward the roller brush 250 through the air outlet hole 114 and perform the drying operation on the roller brush 250. It can be understood that when the base 100 does not perform the drying operation, the cleaning device 1 may be in the cleaning state or the self-cleaning state.

[0079] Optionally, the water blocking component 30 can be located inside the receiving cavity 113 or outside the base body 11. Preferably, the water blocking component 30 is coupled to the receiving cavity 113 of the base body 11. Therefore, the base body 11 can protect the water blocking component 30 to prevent the water blocking component 30 from being damaged.

[0080] Furthermore, the water blocking component 30 includes an elastic member 32 and a water blocking member 34. The water blocking member 34 is movably disposed on the base body 10 along a first direction. The elastic member 32 is deformably connected between the water blocking member 34 and the base body 10 along the first direction. Specifically, the elastic member 32 is used to provide an elastic force for the water blocking member 34. The water blocking member 34 always has a tendency to close the air outlet hole 114 under the drive of the elastic force. Specifically, when the base 100 performs the drying operation, the water blocking member 34 opens the air outlet hole 114 under the action of other external forces besides the elastic force (for example, opened under the action of the roller brush 250 or human force). When the base 100 does not perform the drying operation, the external force is released, and then the water blocking member 34 can re-close the air outlet hole 114 under the action of the elastic force. Thus, by providing the elastic member 32, the water blocking member 34 can be automatically reset, making the closing operation of the air outlet hole 114 simpler.

[0081] Optionally, the elastic member 32 can be one or more. Preferably, the elastic member 32 is multiple. The multiple elastic members 32 act on different positions of the water blocking member 34. In this way, the movement stability of the water blocking member 34 can be effectively improved.

[0082] A positioning post 345 is further provided on the bottom surface of the water blocking member 34. A positioning groove 116 is further protrudingly provided on the inner bottom wall of the base body 11. The elastic member 32 is a compression spring. One end of the elastic member 32 is sleeved on the positioning post 345, and the other end extends into the positioning groove 116 and abuts against the bottom of the positioning groove 116 to improve the telescopic stability of the elastic member 32.

[0083] Optionally, the first direction can intersect with the height direction of the base body 10 or coincide with the height direction of the base body 10. The following embodiments are described by taking the first direction as the height direction of the base body 10 as an example.

[0084] Further, the water blocking assembly 30 includes a driving member 36 and a water blocking member 34. The water blocking member 34 is movably disposed on the base 10 in the first direction. The driving member 36 is in transmission connection with the water blocking member 34, and the driving member 36 is configured to drive the water blocking member 34 to open the air outlet 114 when the base 100 performs a drying operation.

[0085] It can be understood that the water blocking member 34 can open or close the air outlet 114 under the action of the driving member 36, or can open the air outlet 114 under the action of the driving member 36 and close the air outlet 114 under the action of the elastic member 32. By providing the driving member 36, the trouble of manual setting can be reduced, so that the water blocking assembly 30 can automatically open or close the air outlet 114.

[0086] Further, please refer to Figure 6 simultaneously. The driving member 36 includes a driving body 361 and a pushing block 363. The driving body 361 is disposed on the base 10. The pushing block 363 is in transmission connection with the driving body 361 and moves relative to the base 10 in a second direction intersecting the first direction. Wherein, during the movement of the pushing block 363 in the second direction, the water blocking member 34 descends relative to the base 10 in the first direction under the drive of the pushing block 363 and opens the air outlet 114. Specifically, the second direction can intersect with the width direction of the base 10 or can coincide with the width direction of the base 10. The following embodiments will be described by taking the second direction as the width direction of the base 10 as an example.

[0087] Compared with the way that the pushing block 363 moves in the first direction and drives the water blocking member 34 to move in the first direction, the movement mode provided by this embodiment can improve the rationality and compactness of the internal space layout of the base 10, so that the internal space of the base 10 has better space utilization.

[0088] Further, the pushing block 363 has a first guiding surface 3632 facing the water blocking member 34, and there is a height difference in the first direction on the first guiding surface 3632. The water blocking member 34 descends relative to the base 10 in the first direction under the drive of the first guiding surface 3632 and opens the air outlet 114.

[0089] By providing the first guiding surface 3632, the cooperation between the first guiding surface 3632 and the water blocking member 34 can convert the movement of the pushing block 363 in the second direction into the movement of the water blocking member 34 in the first direction. In this way, the rationality and compactness of the internal space layout of the base 10 can be further improved.

[0090] Of course, the way the pushing block 363 drives the water baffle 34 is not limited to the above one. In some other embodiments, a first guiding surface 3632 may also be provided on the water baffle 34. Optionally, the driving body 361 may be a solenoid valve, a telescopic cylinder or other structures, which are not specifically defined here. The driving body 361 is electrically connected to the controller. When the controller sends a drying signal to the driving body 361, the driving body 361 drives the pushing block 363 to slide in the second direction so that the first guiding surface 3632 can abut against the water baffle 34. Furthermore, the pushing block 363 pushes the water baffle 34 to slide. When the controller sends a drying end signal to the driving body 361, the driving body 361 drives the pushing block 363 to slide in the reverse direction so that the pushing block 363 can be separated from the water baffle 34. Optionally, the first guiding surface 3632 may be a curved surface, an inclined surface or other surface structures. Preferably, the first guiding surface 3632 is an inclined surface that slopes downward along the descending direction of the water baffle 34. The inclined surface has a simpler setting direction compared to the curved surface, and when the inclined surface drives the water baffle 34 to descend, the movement of the water baffle 34 can be made more stable.

[0091] Furthermore, the water baffle 34 has a second guiding surface 347 that cooperates with the first guiding surface 3632, and the second guiding surface 347 is an inclined surface that fits the first guiding surface 3632. In this way, the contact area between the water baffle 34 and the pushing block 363 can be increased, so that the water baffle 34 can descend stably under the action of the pushing block 363.

[0092] Specifically, the water baffle 34 includes a water baffle main body 341 and a water baffle accessory part 343 connected to the water baffle main body 341. The water baffle main body 341 is plate-shaped and extends along the second direction. The elastic member 32 abuts between the inner bottom wall of the seat main body 11 and the bottom surface of the water baffle main body 341 and is used to always provide an upward elastic force for the water baffle main body 341. The second guiding surface 347 is formed on the water baffle accessory part 343.

[0093] When the base 100 does not perform the drying operation, the pushing block 363 is separated from the water baffle accessory part 343, and the water baffle main body 341 closes the air outlet 114 under the action of the elastic member 32. When the base 100 needs to perform the drying operation, the driving body 361 drives the pushing block 363 to slide in the second direction so that the first guiding surface 3632 of the pushing block 363 can abut against the second guiding surface 347 on the water baffle accessory part 343. Then, as the pushing block 363 continues to move in the original direction, under the action of the pushing block 363, the water baffle main body 341 descends and opens the air outlet 114. When the drying operation of the base 100 ends, the driving body 361 drives the pushing block 363 to slide in the reverse direction until the pushing block 363 is separated from the water baffle main body 341, and the water baffle 34 rises under the action of the elastic member 32 and closes the air outlet 114.

[0094] The water blocking assembly 30 further includes a reset member 38. The reset member 38 is deformably connected between the push block 363 and the water blocking member 34 and is used to provide a reset force for resetting the push block 363. Under the action of the reset force, after the base 100 finishes the drying operation, the push block 363 can slide reversely under the combined action of the reset member 38 and the driving body 361, so that the push block 363 can be separated from the water blocking main body 341.

[0095] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0096] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
