Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to an air duct structure, cleaning equipment and a cleaning system. Background Art

[0002] Cleaning equipment (such as vacuum cleaners) uses an electric motor to drive the blades to rotate at high speed, creating negative air pressure in the sealed shell, which in turn sucks external dust into the dust cup.

[0003] In the existing technology, a self-dust collection base station can be equipped. After the vacuum cleaner is used, in order to prevent bacteria from growing inside the dust cup, the dust cup needs to be placed on the self-dust collection base station, and the dust in the dust cup is collected into the dust bag of the self-dust collection base station through the suction motor on the self-dust collection base station.

[0004] However, the above-mentioned self-dust collection base station needs to be equipped with a suction motor, which is relatively expensive. Utility Model Content

[0095] The following exemplary embodiments are described in detail, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0096] In the prior art, after the vacuum cleaner has cleaned the floor, the dust is collected in the dust cup. If the dust in the dust cup is not dumped out in time, bacteria will grow inside the dust cup. To facilitate the cleaning of the dust cup, the vacuum cleaner is usually equipped with a self-dust collection base station. After using the vacuum cleaner, the dust cup needs to be placed on the self-dust collection base station, and the dust cup is opened by the self-dust collection base station. After that, the suction motor on the self-dust collection base station is turned on, and the dust in the dust cup is sucked into the dust bag of the self-dust collection base station through the suction motor, and then the dust in the dust cup can be cleaned. However, the above-mentioned self-dust collection base station itself is also equivalent to a vacuum cleaner, and must be equipped with a suction motor. Only under the action of the suction motor can the dust be sucked into the dust bag, but the cost of the suction motor is relatively high, which leads to a high cost of setting up the above-mentioned base station.

[0097] Based on this, an embodiment of the present application provides an air duct structure. When the rotating member rotates to a first state relative to the supporting member, the dust cup assembly and the motor assembly of the cleaning equipment are connected through the first air duct and the second air duct, and then the external dust can be sucked into the dust cup assembly through the motor assembly. When the rotating member rotates to a second state relative to the supporting member, the motor assembly is connected to the base station through the third channel, and the dust cup assembly is also connected to the base station, so that the dust in the dust cup assembly can be collected to the base station through the motor assembly. In this way, the base station does not need to be equipped with a motor, which reduces the cost of setting up the base station.

[0098] The specific implementation of the floor brush structure and cleaning device provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0099] Reference Figures 1 to 19 The air duct structure 100 provided in the present application is used for cleaning equipment. The air duct structure 100 includes: a support member 200 and a rotating member 300. The support member 200 is provided with a first air duct 211 for communicating with the dust cup assembly 800 of the cleaning equipment. The rotating member 300 is connected to the support member 200, and the rotating member 300 is provided with a second air duct 311 and a third air duct 321 that are connected.

[0100] The rotating member 300 is configured to rotate relative to the supporting member 200 to switch between a first state and a second state. In the first state, the second air duct 311 is connected to the first air duct 211, and the third air duct 321 is closed to connect the dust cup assembly 800 and the motor assembly 700 of the cleaning device; in the second state, the second air duct 311 and the first air duct 211 are closed to connect the motor assembly 700 and the third air duct 321. The third air duct 321 is used to connect to the dust cup assembly 800 through the base station 10 when connected to the motor assembly 700, so as to suck the dust in the dust cup assembly 800 into the base station 10 through the motor assembly 700.

[0101] In the present application, the motor assembly 700, the rotating member 300, the support member 200, and the dust cup assembly 800 are arranged in sequence. The cleaning device also includes a mounting base 900, on which the motor assembly 700, the support member 200, and the dust cup assembly 800 are all arranged.

[0102] For example, in order to facilitate the rotation of the rotating member 300 relative to the supporting member 200 , a rotating bearing 250 may be provided between the rotating member 300 and the supporting member 200 , and the rotating member 300 is connected to the supporting member 200 via the rotating bearing 250 .

[0103] In a specific implementation, the dust cup assembly 800 has an air inlet 810, and the motor assembly 700 has an air outlet. In the first state, the air inlet 810 is sequentially connected to the interior of the dust cup assembly 800, the first air duct 211, the second air duct 311, and the air outlet, so that dust is sucked into the dust cup assembly 800 through the motor assembly 700. In the second state, the air inlet 810 is sequentially connected to the interior of the dust cup assembly 800, the base station 10, the third air duct 321, and the air outlet, so that dust inside the dust cup assembly 800 is sucked into the base station 10 through the motor assembly 700, and the dust inside the dust cup assembly 800 is collected in the base station 10.

[0104] The air duct structure 100 provided in the present application is such that when the rotating member 300 rotates to a first state relative to the support member 200, the dust cup assembly 800 and the motor assembly 700 of the cleaning device are connected through the first air duct 211 and the second air duct 311, and then the external dust and debris can be sucked into the dust cup assembly 800 through the motor assembly 700. When the rotating member 300 rotates to a second state relative to the support member 200, the motor assembly 700 is connected to the base station 10 through the third channel, and the dust cup assembly 800 is also connected to the base station 10, so that the dust and debris in the dust cup assembly 800 can be collected to the base station 10 through the motor assembly 700. In this way, the base station 10 does not need to be equipped with a motor, which reduces the installation cost of the base station 10.

[0105] Reference Figure 2 and Figure 3 As shown, the air duct structure 100 provided in the present application includes a rotating member 300 comprising a rotating member body 310 and a first retaining ring 320. The rotating member body 310 is provided with a first connecting portion 312, which is rotatably connected to the support member 200. The second air duct 311 is provided on the rotating member body 310; the first retaining ring 320 is provided on the rotating member body 310, and the third air duct 321 is provided on the first retaining ring 320.

[0106] For example, the first connection portion 312 can be a hole or a shaft provided in the middle region of the rotating member body 310. The first connection portion 312 is plugged into the support member 200, thereby allowing the rotating member 300 to rotate relative to the support member 200. Alternatively, the first retaining ring 320 can be inserted into the support member 200 as the first connection portion 312.

[0107] Thus, by providing the first connecting portion 312, the first connecting portion 312 is rotatably connected to the support member 200, so that the rotating member 300 can rotate relative to the support member 200. By providing the first retaining ring 320 and disposing the third air duct 321 on the first retaining ring 320, the motor assembly 700 can communicate with the outside world through the third air duct 321.

[0108] Reference Figure 3 As shown, in the air duct structure 100 provided in the present application, the first retaining ring 320 and the rotating member body 310 are jointly arranged to form an air duct cavity 330 , and the second air duct 311 and the third air duct 321 are connected through the air duct cavity 330 .

[0109] The first retaining ring 320 is disposed around the circumference of the rotating member body 310 to form an air duct cavity 330 together with the rotating member body 310 .

[0110] In this way, by providing the air duct cavity 330 , the motor assembly 700 can communicate with the second air duct 311 or the third air duct 321 through the air duct cavity 330 .

[0111] Reference Figure 2 As shown, the air duct structure 100 provided in the present application includes a support member 200 comprising: a support member body 210 and a second retaining ring 220. The support member body 210 is provided with a second connecting portion 212, which is rotatably connected to the rotating member 300. The first air duct 211 is provided on the support member body 210; the second retaining ring 220 is provided on the support member body 210, and the second retaining ring 220 is used to connect to the dust cup assembly 800.

[0112] For example, the first connection portion 312 can be a hole or a shaft provided in the middle region of the rotating member body 310. The first connection portion 312 is plugged into the support member 200, thereby allowing the first connection portion 312 to rotate relative to the support member 200. Alternatively, the first connection portion 312 can be a support portion 240 sleeved on the first retaining ring 320.

[0113] Specifically, the support member body 210 is opposite to the rotating member body 310 so as to facilitate communication between the first air duct 211 and the second air duct 311. The second retaining ring 220 is disposed around the circumference of the support member 210 body.

[0114] In some embodiments, the support body 210 is connected to the motor assembly 700 by screws or bolts to fix the rotating member 300 between the support body 210 and the motor assembly 700 .

[0115] In this way, by providing the second connecting portion 212, the second connecting portion 212 is rotatably connected to the rotating member 300, so that the rotating member 300 can rotate relative to the support member 200. By providing the second retaining ring 220, the support member 200 is connected to the dust cup assembly 800.

[0116] Reference Figure 2 As shown, the air duct structure 100 provided in the present application has a plurality of second air ducts 311 , and the second air ducts 311 are evenly spaced around the rotation axis of the rotating member 300 .

[0117] There are multiple first air ducts 211 . In the first state, the second air ducts 311 and the first air ducts 211 are connected in a one-to-one correspondence; in the second state, the second air ducts 311 and the first air ducts 211 are staggered.

[0118] It can be understood that the first air duct 211 is a through hole provided on the support member body 210 , and the second air duct 311 is a through hole provided on the rotating member body 310 .

[0119] For example, the second air duct 311 may be fan-shaped, with the inner and outer centers of the second air duct 311 both located on the rotation axis of the rotating member 300. The shape and number of the first air duct 211 may be the same as those of the second air duct 311.

[0120] In the present application, in the first state, the first air duct 211 and the second air duct 311 are opposite to each other, so that the first air duct 211 is connected to the second air duct 311. In the second state, the second air duct 311 is located between two adjacent first air ducts 211, so that the second air duct 311 is staggered with the first air duct 211, thereby closing the first air duct 211.

[0121] In this way, by rotating the rotating member 300 relative to the supporting member 200, the first air duct 211 and the second air duct 311 can be connected or staggered correspondingly, and the operation is relatively simple and convenient.

[0122] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 7 As shown, referring to the figure, the air duct structure 100 provided in the present application also includes a driving member 410, which is connected to the rotating member 300 to drive the rotating member 300 to rotate relative to the supporting member 200, so that the rotating member 300 switches from the first state to the second state.

[0123] In one possible embodiment, the driving member 410 is a driving rod disposed on one side of the third air duct 321. By rotating the driving member 410 relative to the support member 200, the rotating member 300 is driven to rotate relative to the support member 200, thereby enabling the support member 200 to block the third air duct 321 or to not block the third air duct 321. Specifically, the support member 200 blocks the third air duct 321, thereby sealing the third air duct 321. When the support member 200 does not block the third air duct 321, the third air duct 321 is connected to the outside world.

[0124] In this way, by providing the driving member 410 , the rotating member 300 can be switched from the first state to the second state more conveniently.

When the base station 10 is connected to the cleaning device, the dust bag assembly 11 is located below the dust cup assembly 800, and the lower cover of the dust cup assembly 800 is opened and communicated with the interior of the dust bag assembly 11. The connecting piece 12 connects the dust bag assembly 11 with the third air duct 321. Thus, in the second state, the air inlet 810, the interior of the dust cup assembly 800, the interior of the dust bag assembly 11, the connecting piece 12, the third air duct 321 and the air outlet of the motor assembly 700 can be communicated. At this time, the air flow enters the dust cup assembly 800 from the air inlet 810 and, under the action of the motor assembly 700, flows along the third air duct 321. Figure 19The dust flows along the path indicated by the dotted arrow, and the dust in the dust cup assembly 800 can be collected in the dust bag assembly 11 under the action of the motor assembly 700. Therefore, the cleaning system provided by the embodiment of the present application can collect the dust in the dust cup assembly 800 through the base station 10 without installing a motor on the base station 10, thereby reducing the installation cost of the base station 10.
