Description

Technical Field

[0001] The invention belongs to the technical field of cleaning electrical appliances, and in particular relates to a handheld vacuum cleaner for internal dust cleaning. Background Art

[0002] As a cordless vacuum cleaner, a handheld vacuum cleaner mainly includes a vacuum cleaner body, a vacuum head (floor brush), a vacuum tube connecting the vacuum head with the vacuum cleaner body, and a conductive component for connecting the circuits of the vacuum cleaner body and the vacuum head. Under the control of the vacuum cleaner body, electricity is directed to the vacuum head through the conductive component, so that the vacuum head starts working.

[0003] When most vacuum cleaners on the market are in use, air is allowed to enter the interior of the vacuum cleaner and is filtered through a filter element to filter out dust and other impurities, so that the dust and other impurities are stored in a dust bin.

[0004] As for the filter element, it is often clogged with dust during use, which affects the dust collection efficiency, so it needs to be cleaned frequently. There are generally two ways to clean the vacuum cleaner: cleaning the filter element and directly replacing the filter element. The steps for cleaning the filter element are cumbersome and the user experience is poor; replacing the filter element is prone to waste and the replacement frequency is high. Summary of the invention

[0049] The filter assembly 3 is built in the housing 11 . The filter assembly 3 is located at one end of the motor assembly 12 . A scraper 4 is provided in the filter assembly 3 , and the scraper 4 is movably connected to the filter assembly 3 .

[0050] The filter assembly 3 includes a filter support 31, a filter core 32 and a filter screen 33. The filter screen 33 is sleeved on the filter support 31. The filter core 32 is arranged in the filter support 31. The scraper 4 is movably connected to the filter core 32. In this way, the dust on the inner surface of the filter core can be scraped off by the up and down movement of the scraper, so as to achieve the purpose of cleaning the filter core and solve the problem that the filter core in the vacuum cleaner is often blocked by dust during use, which affects the dust collection efficiency.

[0051] The filter core 32 is a hollow cylinder with openings at both ends, and the scraper 4 is in close contact with the inner surface of the filter core 32. The scraping quality can be improved, and a plurality of through holes are provided on the scraper, which does not affect the circulation of airflow.

[0052] In one embodiment, Figure 4 A plurality of first springs 5 ​​are provided at one end of the scraper 4, and the first springs 5 ​​are connected to the bottom of the filter core 32. A plurality of second springs 6 are provided at the other end of the scraper 4, and the second springs 6 are connected to the top of the filter core 32. When cleaning the filter core, the scraper can be pushed up and down to facilitate cleaning of the inner surface of the filter core.

[0053] In another embodiment, Figure 5-6The motor assembly 12 includes a motor 121, a fan blade and a motor cover 122. The fan blade is arranged on the output shaft 7 of the motor 121, and the fan blade is located in the motor cover 122.

When the motor drives the extension rod to rotate, the extension rod drives the rotating column to rotate, so that the U-shaped frame can slide along the V-shaped slot, so that one V-shaped slot slides to another V-shaped slot. The U-shaped frame reciprocates along the axial direction of the rotating column, thereby driving the connecting rod to reciprocate, and then realizing the reciprocating motion of the scraper.

[0055] Working principle: By setting a scraper in the filter element, the scraper fits with the inner surface of the filter element, so that the dust on the inner surface of the filter element can be scraped off by the up and down movement of the scraper, so as to achieve the purpose of cleaning the filter element and solve the problem that the filter element in the vacuum cleaner is often blocked by dust during use, which affects the dust collection efficiency. In the present invention, the housing, the motor assembly and the air duct are arranged in parallel. When the motor assembly is working, the wind flows into the housing through the air duct, and is discharged after passing through the filter assembly and the motor assembly. The wind flows almost in a straight line, which can reduce wind loss and improve dust collection efficiency.
