Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners, and in particular relates to a cleaning device with the functions of dust suction, self-cleaning and dust collection. Background Art

[0002] Vacuum cleaners are often used in daily life. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, creating negative air pressure in the sealed shell to absorb dust. Existing handheld vacuum cleaners often fill up easily due to their small dust cups. Therefore, the dust cup needs to be opened and emptied after each use, which is very inconvenient to clean. For this reason, a matching vacuum cleaner base station has emerged. The vacuum cleaner base station can be used to collect, store and process dust and debris generated by the vacuum cleaner, greatly reducing the vacuum cleaner cleaning cycle and cleaning the filter, thereby reducing the cleaning burden on the user. Most existing vacuum cleaner base stations require motors, which are complex in structure and high in cost.

[0003] Upon investigation, the Chinese patent application number CN202310651739.8, "A Vacuum Cleaner and Cleaning Device," includes a body assembly, a dust cup assembly, and a fan assembly. The dust cup assembly includes a filter assembly. The fan assembly is rotatably connected to the body assembly, and at least two independent air ducts are formed between the fan assembly and the dust cup assembly. The vacuum cleaner is provided with a push assembly that is triggered when it is placed on the base station to drive the fan assembly to rotate to achieve air duct switching. After the fan assembly is pushed by the push assembly to achieve air duct switching, it blows air into the dust cup assembly through the switched air duct to connect the dust cup body and the base station and perform the self-cleaning operation of the filter assembly and the dust cup body, as well as the self-dust collection operation of introducing the dust in the dust cup body and the filter assembly into the base station. The base station of this structure adopts positive pressure self-cleaning, and does not require a suction device, which reduces costs. However, there are two push assemblies to achieve air duct switching, which is relatively complex in structure, high in cost, and cumbersome to assemble. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a cleaning device with simple and reasonable structure, convenient operation and the functions of dust suction, self-cleaning and dust collection in response to the above technical status quo.

[0014] It is characterized in that: the air duct switching mechanism has:

[0015] An air inlet plate is provided at the lower end of the main unit and has a circular cavity in the middle which is connected to the inlet of the dust cup;

[0016] A return air inlet pipe is arranged on the side of the air inlet disk, communicates with the circular cavity, and is plugged into the dust collection return air duct;

When the vacuum cleaner is placed in the base station, the paddle moves downward along the slide groove and rotates to realize the switching of the air duct.

[0019] Furthermore, the slide member is vertically arranged at the upper end of the insertion cavity corresponding to the position of the paddle, and is integrated with the dust collection return air duct into an integral part.

[0020] Furthermore, the inner surface of the rim of the insertion cavity gradually shrinks inwards downwards, cooperating with the dust cover opening button on the side of the lower end of the dust cup.

[0021] Furthermore, the dust collecting return air duct is in an inverted L shape, the lower part of the dust collecting return air duct is connected to the base, and the upper part is plug-connected to the outer opening of the return air inlet duct of the air inlet disk.

[0025] Furthermore, the inner side surface of the return air inlet duct is also an arc surface that is adapted to the size of the circular cavity.

[0026] Finally, the dust collecting container adopts a dust collecting hopper or a dust collecting bag.

[0027] Compared with the existing technology, the advantages of this utility model are: the air duct switching member uses a rotating method to switch between the dust collection and dust collection air ducts. The rotation is achieved by the paddle and the slide member. That is, when the vacuum cleaner is installed in the base station, it switches from dust collection mode to dust collection mode, and when the vacuum cleaner leaves the base station, it switches back to dust collection mode, which is very convenient to operate. The utility model has a reasonable structural design and is easy to operate. At the same time, the base station does not need to be equipped with a motor, which effectively reduces costs and facilitates dust removal and cleaning of the vacuum cleaner, making it practical and convenient.

[0038] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1 to 10 As shown, a cleaning device with dust suction, self-cleaning and dust collection functions includes:

[0040] A vacuum cleaner A, comprising:

[0041] A main unit 2, having a motor and a fan blade capable of sucking air, capable of sucking or blowing away dust;

[0042] A dust cup 3, a separation component 8 with a separation function such as a filter, a dust collecting cup body and a cup cover 31 that are sleeved outside the separation component 8;

[0043] A dust suction pipe 4, used to suck the dusty air from the outside;

[0044] A dust collection base station 1, comprising:

[0045] A base 11, the upper portion of which is an insertion cavity 111 for inserting the vacuum cleaner A, and the lower portion of which is a dust collection cavity 112, which is connected to the insertion cavity 111; and a door cover that can be opened;

[0046] a dust collecting container 9, disposed in the dust collecting cavity 112;

[0047] A dust collection return air duct 12 is arranged on the base 11 and is connected to the main unit 2 through plugging; the vacuum cleaner A has a dust collection air duct, and can be connected to form a dust blowing air duct 20 through the dust cup 3, the insertion cavity 111 of the base 11, the dust collection cavity 112, the dust collection return air duct 12 and the air duct switching mechanism B in the main unit 2.

[0048] The air duct switching mechanism B includes an air inlet plate 6 and an air duct switching member 7. The air inlet plate 6 is disposed at the lower end of the main unit 2 and has a circular cavity 62 in the middle that communicates with the inlet of the dust cup 3. A return air inlet duct 61 is disposed on the side of the air inlet plate 6, communicating with the circular cavity 62 and allowing the dust collection return air duct 12 to plug in. The inner surface of the return air inlet duct 61 is also an arc-shaped surface that matches the size of the circular cavity 62. The air duct switching member 7 is rotatably disposed in the circular cavity 62 and selectively connects with the inner opening of the return air inlet duct 61 or isolates it from the circular cavity 62 and connects it to the circular cavity 62. The air duct switching member 7 is provided with a paddle 70 that extends through the air inlet plate 6 and out of the housing of the main unit 2. The base 11 is provided with a slide member 13, which is vertically positioned at the upper end of the insertion cavity 111, corresponding to the position of the paddle 70. It can also be integrated with the dust collection return air duct 12 into a single piece, facilitating design. The inner surface of the slide member 13 has a slide 131 that cooperates with the paddle 70. The slide 131 is tilted downward. When the vacuum cleaner A is placed in the base 1, the paddle 70 moves downward along the slide 131 and rotates, thereby driving the air duct switching member 7 to rotate and switch the air duct. The inner surface 113 of the rim of the insertion cavity 111 gradually contracts inward, cooperating with the dust cover opening button 30 on the lower side of the dust cup 3, so that the dust cup cover 31 automatically opens after the vacuum cleaner A is placed in place. The dust collection return air duct 12 is in an inverted L-shape, with the lower portion of the dust collection return air duct 12 connected to the base 11 and the upper portion plugging into the outer opening of the return air inlet duct 61 of the air inlet disk 6. The air inlet plate 6 is provided with a fan-shaped, inwardly concave limiting sliding groove 63 on the side of the return air inlet pipe 61. The side of the limiting sliding groove 63 is open for the paddle 70 to pass through.

[0049] The air duct switching member 7 is a hollow disc-shaped structure with a hollow portion 76. The top surface of the air duct switching member 7 is provided with an opening that is connected to the circular cavity 62 of the air inlet disk 6. The top surface opening of the air duct switching member 7 extends upward and is provided with a folded circular ring buckle 73 that is buckled with the upper end opening of the circular cavity 62 of the air inlet disk 6 and can rotate; the side of the air duct switching member 7 has an outward extension portion 74, and the extension portion 74 has an extended air duct 75 that connects the switching air outlet 71 on the arc-shaped side of the extension portion with the hollow portion 76 of the air duct switching member 7, and the extension portion 74 has an arc-shaped connecting portion 72 to the left side for connecting the paddle 70, and the left part of the connecting portion 72 has a sealing member 77, which cooperates with the side opening of the limiting slide groove 63 to seal.

[0050] The dust collecting container 9 adopts a dust collecting hopper or a dust collecting bag.

[0051] The main unit 2 of the vacuum cleaner A is provided with a motor 5 and a filter. The working principle of the vacuum cleaner A is consistent with the prior art.

[0052] Here’s how it works:

[0053] When the vacuum cleaner A is vacuuming, the position of the paddle 70 is as follows: Figure 8 As shown in (b), the air duct switching member 7 closes the return air inlet duct 61, and the dust-laden air enters from the dust suction pipe 4 of the vacuum cleaner A, passes through the dust suction air duct 10, and is filtered by the filter. The clean air enters the circular cavity 62 of the air inlet disk 6, enters the motor cover through the switching air port 71 of the air duct switching member 7, and is finally discharged from the air outlet. The dust falls into the dust cup 3, as shown in FIG. Figure 10 shown.

[0054] When the vacuum cleaner A has finished vacuuming and needs to empty the dust, the vacuum cleaner A is installed in the base station 1, wherein the dust cup 3 is aligned with the insertion cavity 111 of the base 11 and inserted, and the paddle 70 is inserted into the slide groove 131 and moved down along the slide groove. After being assembled in place, the position of the paddle 70 is as shown in FIG. Figure 8 As shown in (a), the switching air port 71 of the air duct switching member 7 is connected to the return air inlet duct 61, the dust collecting air duct 20 is opened, and at the same time, the dust suction air duct 10 is closed, and the dust cover opening button 30 is pressed against the inner wall of the insertion cavity 111 to open, as shown in FIG. Figure 7 The motor drives the fan blades, and the airflow passes through the dust cup 3, sucking the garbage in the dust cup 3 into the bottom dust bag 9, and then returns to the main unit 2 through the insertion cavity 111 of the base 11, the dust collection cavity 112, and the dust collection return duct 12, passes through the motor cover, and is finally discharged from the air outlet. Figure 5 .

[0055] In this way, the paddle 70 cooperates with the chute 131 to drive the air duct switching member 7 to rotate, and the air duct switching member 7 rotates to switch between dust collection and dust collection. That is, when the vacuum cleaner A is installed in the base station 1, it switches from dust collection mode to dust collection mode, and when the vacuum cleaner A leaves the base station 1, it switches back to dust collection mode. This is very convenient operation, and there is no need to install a motor in the base station 1. Only the motor 5 of the vacuum cleaner A can suck the garbage from the dust cup 3 into the dust bag 9.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
