Description

Technical Field

[0001] The invention 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 vacuum cleaners is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, and absorb dust. Existing handheld vacuum cleaners are often easily filled due to their small dust cups. Therefore, the dust cups need to be opened and emptied after each use, which is very inconvenient to clean. For this reason, matching vacuum cleaner base stations have 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 can clean the filter, thereby reducing the user's cleaning burden. Most existing vacuum cleaner base stations need to be equipped with motors, which are complex in structure and high in cost.

[0003] After investigation, the Chinese patent "A Vacuum Cleaner and Cleaning Equipment" with the existing patent application number CN202310651739.8 includes a body component, a dust cup component and a fan component. The dust cup component includes a filter component. The fan component is rotatably connected to the body component and at least two independent air ducts are formed between the fan component and the dust cup component. The vacuum cleaner is provided with a push component that is triggered to drive the fan component to rotate when it is placed on the base station to achieve air duct switching. After the fan component is pushed by the push component to achieve air duct switching, it blows air into the dust cup component through the switched air duct to connect the dust cup body and the base station and perform the self-cleaning operation of the filter component and the dust cup body and the self-dust collection operation of introducing the dust in the dust cup body and the filter component into the base station. The base station of this structure adopts positive pressure self-cleaning, and there is no need to set up a suction device, which reduces the cost, but there are two push components to achieve air duct switching, the structure is relatively complex, the cost is high, and the assembly is also relatively troublesome. Summary of the invention

[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 view of the above technical status quo.

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 groove 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 member.

[0020] Furthermore, the inner surface of the edge of the insertion cavity gradually shrinks inwards downwards and cooperates 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 portion of the dust collecting return air duct is connected to the base, and the upper portion 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 matches 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 prior art, the advantages of the present invention are: the air duct switching member adopts a rotating method to realize the switching of the dust suction and dust collection air ducts, and the rotation is achieved by cooperating with the paddle and the slide member, that is, when the vacuum cleaner is installed in the base station, it is switched from the dust suction mode to the dust collection mode, and when the vacuum cleaner leaves the base station, it is switched to the dust suction mode, which is very convenient to operate. The present invention 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 the cost, facilitates the dust removal and cleaning of the vacuum cleaner, and is practical and convenient.

[0038] The present invention is further described in detail below with reference to the accompanying drawings.

[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 host 2, having a motor and a fan blade capable of sucking air, and capable of sucking or blowing 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 which 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 collecting base station 1, comprising:

[0045] A base 11, the upper part of which is an insertion cavity 111, for inserting the vacuum cleaner A, and the lower part of which is a dust collecting cavity 112, which is connected to the insertion cavity 111; and has an openable door cover;

[0046] A dust collecting container 9 is disposed in the dust collecting cavity 112;

[0047] A dust collection return air duct 12 is arranged on the base 11 and is plugged and connected to the main unit 2; 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 disc 6 and an air duct switching member 7. The air inlet disc 6 is arranged at the lower end of the main unit 2, and has a circular cavity 62 in the middle that is connected to the inlet of the dust cup 3. A return air inlet pipe 61 is arranged on the side of the air inlet disc 6, which is connected to the circular cavity 62 and is plugged into the dust collection return air duct 12. The inner side of the return air inlet pipe 61 is also an arc surface that matches the size of the circular cavity 62. The air duct switching member 7 is rotatably arranged in the circular cavity 62, and is selectively connected to the inner opening of the return air inlet pipe 61 or isolated and connected to the circular cavity 62 by rotation, and has a paddle 70, which passes through the air inlet disc 6 and extends out of the housing of the main unit 2. A slide member 13 is provided on the base 11. The slide member 13 is vertically arranged at the upper end of the insertion cavity 111 and corresponds to the position of the paddle 70. It can also be integrated with the dust collection return air duct 12 into an integral part, which is convenient for shape design; the inner surface of the slide member 13 has a slide 131 that cooperates with the paddle 70. The slide 131 is arranged to be tilted downward. When the vacuum cleaner A is placed in the base station 1, the paddle 70 moves downward along the slide 131 and rotates, thereby driving the air duct switching member 7 to rotate and realize the switching of the air duct. The inner surface 113 of the edge of the insertion cavity 111 gradually shrinks inward downward, and cooperates with the dust cover opening button 30 on the lower side of the dust cup 3, so that after the vacuum cleaner A is put in place, the dust cup cover 31 automatically opens. The dust collection return air duct 12 is inverted L-shaped, the lower part of the dust collection return air duct 12 is connected to the base 11, and the upper part is plug-connected with the outer opening of the return air inlet pipe 61 of the air inlet disk 6. The air inlet plate 6 is provided with a fan-shaped, inwardly concave limiting slide groove 63 on the side of the return air inlet pipe 61 , and the side of the limiting slide 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 extension air duct 75 that connects the switching air outlet 71 on the arc-shaped side surface 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 that cooperates with the side opening of the limiting slide groove 63 for sealing.

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

[0051] A motor 5 and a filter are arranged inside the main body 2 of the vacuum cleaner A, and 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 dusty air enters from the dust suction pipe 4 of the vacuum cleaner A, passes through the dust suction air duct 10, is filtered by the filter, and 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, and the dust falls into the dust cup 3, as shown in FIG. Fig.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 pipe 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 air 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 slide slot 131 to drive the air duct switching member 7 to rotate, and the air duct switching between dust suction and dust collection is realized by the rotation of the air duct switching member 7, that is, the vacuum cleaner A is switched from the dust suction mode to the dust collection mode when it is installed in the base station 1, and the vacuum cleaner A is switched to the dust suction mode when it leaves the base station 1. The operation is very convenient, and there is no need to set a motor in the base station 1. Only one 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 the scope of protection of the present invention.
