Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a handheld vacuum cleaner with an integrated filter component. Background Art

[0002] A handheld vacuum cleaner is small in size, very convenient to carry and use. It is a household cleaning product between an ordinary household vacuum cleaner and a portable vacuum cleaner, and is more suitable for cleaning small spaces. The handheld vacuum cleaner can remove dust mainly because an electric blower is installed at its "head". There is a wind impeller on the rotating shaft of the blower. After being powered on, the blower will generate suction and pressure at a speed of 500 revolutions per second. Under the action of suction and pressure, air is discharged at high speed, and the air at the dust suction part in the front end of the blower continuously supplements the air in the blower, resulting in an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure with the external atmospheric pressure. The air enters the dust filter bag through the negative pressure brush, long connecting pipe, elbow pipe, hose and hose joint. Dust and other sundries are retained in the dust filter bag. After the air is purified by the filter element, it is discharged from the tail of the machine body. The handheld vacuum cleaner can be equipped with different components to complete different cleaning tasks. For example, when equipped with a floor brush, it can clean the ground; when equipped with a flat brush, it can clean the sofa surface, bed sheets, curtains, etc.; when equipped with a small suction nozzle, it can remove dust in small corners and dirt in some household appliances.

[0003] The existing handheld vacuum cleaners have the following disadvantages. Its filter component is installed inside the vacuum cleaner main body, so it is inconvenient to remove the filter component. And it is easy to inhale hair inside the vacuum cleaner. The hair is extremely easy to block the mesh holes of the filter net, and the hair is easy to entangle with sundries to form large particle sundries, thus more easily blocking the mesh holes, thereby affecting the dust suction effect of the vacuum cleaner.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0024] The present utility model provides a hand-held vacuum cleaner with an integrated filter component. Please refer to Figures 1-4, including a vacuum cleaner main body 1, a handheld handle 4 is installed at the rear end of the vacuum cleaner main body 1, and rollers 3 are installed at both ends of the vacuum cleaner main body 1. It also includes a filtering structure installed at the dust inlet of the vacuum cleaner main body 1; the filtering structure includes a filtering housing 103 installed at the dust inlet of the vacuum cleaner main body 1, a filter net is installed inside the filtering housing 103, and a hair adhesion assembly 100 is installed on the filtering housing 103.

[0025] Pin shafts 2 are fixedly installed at both ends of the vacuum cleaner main body 1, and the pin shafts 2 are rotatably connected to the rollers 3 through bearings.

[0026] A male snap 107 is provided on the filtering housing 103, a female snap 5 is provided on the vacuum cleaner main body 1, and the male snap 107 and the female snap 5 are snap-connected.

[0027] A sealing ring 6 is provided between the filtering housing 103 and the dust inlet of the vacuum cleaner main body 1. When the male snap 107 and the female snap 5 are snap-connected, the sealing ring 6 is in a compressed state.

[0028] The filter net includes a frame 110, a filter screen 111 is arranged inside the frame 110, and a U-shaped sealing strip 109 is bonded to the frame 110.

[0029] The filtering housing 103 is a hollow structure with openings at both ends, and a through hole 1031 is opened at one end of the filtering housing 103. A groove 1032 is opened on the inner cavity bottom wall of the filtering housing 103. The filter net is inserted into the filtering housing 103 through the through hole 1031, and the through hole 1031 and the inner wall of the filtering housing 103 are in elastic contact with the U-shaped sealing strip 109; thus, large particle debris that is likely to cause blockage will be blocked by the filter net and prevented from entering the vacuum cleaner main body 1. And because the filtering housing 103 has openings at both ends, it is convenient to clean the debris on the filter screen 111; at the same time, the filter net can be quickly pulled out for cleaning.

[0030] The hair adhesion assembly includes a support rod 102 fixedly installed on the filtering housing 103. A plug pin 105 is slidably connected to the support rod 102. A spring 104 is sleeved on the plug pin 105. A sticky paper roller 101 is sleeved on the plug pin 105. There are sticky paper rollers with 100 sheets and 60 sheets on the market, which are used according to needs. A limiting disc 106 is welded to one end of the plug pin 105, and both ends of the spring 104 are welded to the support rod 102 and the limiting disc 106 respectively; when in use, the end of the sticky paper on the sticky paper roller 101 is pulled out and adhered to the edge of the filtering housing 103 (the top edge of the filtering housing 103, so as to prevent the opening of the filtering housing 103 from being blocked). Thus, when vacuuming, when the hair passes through the sticky paper, the hair will be adsorbed on the sticky paper, so as to prevent the hair from entering the filtering housing 103 and blocking the mesh holes of the filter screen 111, and thus prevent the hair from entering the vacuum cleaner main body 1.

[0031] During specific use:

[0032] Pull the bolt 105 outwards, place the adhesive paper roller 101 between the two bolts 105, and under the elastic force of the spring, the bolt 105 is inserted into the hole of the sticker roller 101;

[0033] Pull out the end of the adhesive paper on the adhesive paper roller 101 and bond it to the edge of the filter housing 103. Thus, when vacuuming, when the hair passes through the adhesive paper, the hair will be adsorbed on the adhesive paper, thereby preventing the hair from entering the filter housing 103 and clogging the mesh holes of the filter screen 111, and thus preventing the hair from entering the vacuum cleaner main body 1;

[0034] Under the barrier of the filter screen, large particle debris that is likely to cause blockage will be blocked by the filter screen and prevented from entering the vacuum cleaner main body 1.

[0035] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
