[0021] In order to explain in detail the technical content, structural features, achieved purposes and effects of the utility model, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0022] See also Figure 1 and Figure 2 , which illustrates a drying base 100 of the present application; the drying base 100 can be used for docking a surface cleaning device having a floor brush part with one or a pair of roller brushes, and while the surface cleaning device is docked on the drying base, the surface cleaning device can perform self-cleaning work on one or a pair of roller brushes, and the drying base 100 can perform drying operations on one or more roller brushes after self-cleaning.

[0023] The drying base 100 includes a base body 1 , a fan 2 arranged inside the base body 1 , a heating component 3 , and an air duct device 4 formed on the base body 1 .

[0024] The base 1 is constructed to be supported on a plane and to receive a tray portion 11 of a floor brush of a surface cleaning device, and a boss 12 located at the rear side of the tray portion 11 and protruding upward relative to the tray portion 11. Both the tray portion 11 and the boss 12 are hollow structures.

[0025] The tray portion 11 is designed to support the floor brush portion of the surface cleaning device from the bottom. A front recess 111 and a rear recess 112 are provided on the upper surface of the tray portion 11, one in front of the other. The front-to-back distance between the front recess 111 and the rear recess 112 can be designed in accordance with the front-to-back distance between a pair of roller brushes on the surface cleaning device to be docked. For a surface cleaning device with a floor brush portion having approximately the same front-to-back width, when it is configured with only a single front roller brush, the front recess 111 is adapted to accommodate the front roller brush; when it is configured with a pair of front and rear roller brushes, the front recess 111 and the rear recess 112 will be adapted to accommodate the front roller brush and the rear roller brush, respectively.

[0026] The boss 12 is designed to support the upright body portion of the surface cleaning device. The boss 12 is usually provided with a charging connection terminal (not shown in the figure) that can be coupled with a charging interface on the upright body portion of the surface cleaning device.

[0027] The number of the blower 2 can be one or more, and the blower 2 can output wind with a certain pressure when started. In this embodiment, one or more blowers will be housed inside the boss 12. The blower 2 has an air outlet 21.

[0028] The heating component 3 is also arranged inside the boss 12 and located on the lower side of the fan 12. In this example, the heating component 3 includes a metal fixing base 31 and a heating wire 32 wound around the fixing base 31. The heating wire 32 can convert electrical energy into heat energy.

[0029] The air duct device 4 is capable of guiding the air blown out from the air outlet 21 of the fan 2 to extend toward the front recess 111 and the rear recess 112 of the tray portion 11. In this example, the air duct device 4 includes a first air duct 41 extending from the air outlet 21 toward the front recess 111 and a second air duct 42 extending from the air outlet 21 toward the rear recess 112. The first air duct 41 has a front air outlet 410 located at the front recess 111. The second air duct 42 has a rear air outlet 420 located at the rear recess 112. Among them, the first air duct 41 is designed to be an air duct that is always in a through state, and the second air duct 42 is designed to be an air duct that can be selected to be through or blocked. The user can freely choose to pass through the second air duct 42 or close the second air duct 42 according to needs.

[0030] Part of the heating component 3 will be placed in the first air duct 41 , and the other part of the heating component 3 will be placed in the second air duct 42 , that is, the heating component 3 can provide heat energy to the air flows flowing through the first air duct 41 and the second air duct 42 at the same time.

[0031] Since the channel length of the first air duct 41 is significantly greater than the channel length of the second air duct 42, in order to balance the heat loss of the hot air flow through the air duct, the heating area of ​​the heating component 3 located in the first air duct 41 is preferably designed to be larger than the heating area of ​​the heating component 3 located in the second air duct 42.

[0032] The first air duct 41 includes a first upstream duct section 411 located within the boss 12 and extending in the vertical direction, and a first downstream duct section 412 located within the tray portion 11. The second air duct 42 includes a second upstream duct section 421 located within the boss 12 and extending in the vertical direction, and a second downstream duct section 422 located within the tray portion 11. The second upstream duct section 421 is located in front of the first upstream duct section 411. In this example, the second downstream duct section 422 is located above the first downstream duct section 412.

[0033] An air duct baffle 43 is installed within the tray portion 11. This baffle 43 is designed as a removable component that is assembled inside the tray portion 11 and can be removed separately. The tray portion 11 has a first mounting position and a second mounting position, and the baffle 43 can be attached to either the first or second mounting position.

[0034] like Figure 2 、 3 As shown, when the air duct partition 43 is installed at the first installation position inside the tray portion 11, the first downstream air duct section 412 and the second downstream air duct section 422 are separated from each other by the air duct partition 43. The first downstream air duct section 412 and the second downstream air duct section 422 respectively maintain fluid communication with the first upstream air duct section 411 and the second upstream air duct section 422, and the front air outlet 410 and the rear air outlet 420 can both output hot air. In this example, when the air duct partition 43 is installed at the first installation position inside the tray portion 11, the rear end of the air duct partition 43 abuts the middle position of the lower part of the heat-generating component 3. When the air duct partition 43 is installed at the first installation position, the drying base 100 is suitable for performing a roller brush drying operation on a surface cleaning device carrying a double roller brush.

[0035] like Figure 4 As shown, when the air duct baffle 43 is installed in the second installation position inside the tray portion 11, the rear end of the air duct baffle 43 is offset to one side of the heat-generating component 3, the second downstream air duct section 422 merges into the first downstream air duct section 412, and the first upstream air duct section 411 and the second upstream air duct section 422 are both fluidically connected to the merged air duct section. Only the front air outlet 410 can output heat, etc., and the rear air outlet 420 is closed. When the air duct baffle 43 is installed in the second installation position inside the tray portion 11, the drying base 100 is suitable for performing a roller brush drying operation on a surface cleaning device equipped with a single roller brush.

[0036] The rear portion of the heat-generating component 3 is located in the first upstream channel section 411, and the front portion of the heat-generating component 3 is located in the second upstream channel section 421. The first downstream duct section 412 is located downstream of the heat-generating component 3, and the second downstream duct section 422 is located downstream of the heat-generating component 3. When the duct baffle 43 is installed at the second installation position inside the tray portion 11, the rear end of the duct baffle 43 abuts the middle position of the lower portion of the heat-generating component 3.

[0037] like Figure 3As shown, the air duct partition 43 is attached at the first installation position, and the first air duct 41 and the second air duct 42 are both connected. When the floor brush portion 300 of the surface cleaning device is supported on the tray portion 41, the floor brush portion 300 carrying the front roller brush 301 and the rear roller brush 302 are received by the front recess 111 and the rear recess 112, respectively. The front air outlet 410 and the rear air outlet 420 are respectively facing the front roller brush 301 and the rear roller brush 302. When the fan 2 and the heating component 3 are activated, the hot air is divided into two streams A1 and A2 and flows into the first downstream air duct section 412 and the second downstream air duct section 422, respectively. Finally, it escapes through the front air outlet 410 and the rear air outlet 420, thereby achieving a thermal drying operation for the front roller brush 301 and the rear roller brush 302.

[0038] like Figure 4 As shown, the air duct partition 43 is attached to the second installation position, the first air duct 41 is connected, the second air duct 42 is blocked, and the rear air outlet 420 is closed by the air duct partition 43. When the floor brush portion 500 of the surface cleaning device is supported on the tray portion 41, the floor brush portion 500 carries a single front roller brush 501, which is received by the front recess 111, and the front air outlet 410 faces the front roller brush 501. The fan 2 and the heating element 3 are activated, and hot air B1 flows through the air duct formed by the merger of the first downstream air duct section 412 and the second downstream air duct section 422, and escapes through the air outlet 410, thereby achieving a thermal drying operation on the front roller brush 501.
