Problems solved by technology

When the dust cup is removed, the dust can easily enter the air intake duct, and when the air intake duct is vacuumed, the outside air enters the dust cup, which affects the dust entering the dust cup
In addition, the current vacuum cleaners often have the function of dust scraping. During the dust scraping process, defects in the existing structure are more likely to cause dust

Embodiment 1

[0031] refer to Figure 1-Figure 8 , a sealing assembly of a cleaning device, including a first sealing member 511 , a second sealing member 512 , a third sealing member 52 and an annular member 50 .

[0032] The first seal 511 is located at the edge of the inner tube 22 of the dust cup 20 to form a blocking structure that prevents outside air from entering the primary dust area 200 of the dust cup 20; when the cleaning device is working, the second seal 512 is located in the primary dust area Between 200 and the secondary dust area 300, a blocking structure of the primary dust area 200 and the secondary dust area 300 is formed.

[0033] The third sealing member 52 is located between the outer cylinder 21 of the dust cup 20 and the filter 30 to form a blocking structure that prevents outside air from entering the dust cup 20 .

[0034] Specifically, the first sealing member 511 abuts against the edge of the inner cylinder 22 of the dust cup 20 and the outer wall of the air in...

Embodiment 2

[0050] Accordingly, refer to Figure 1-Figure 4 , Figure 7-Figure 8 , The present invention also provides a cleaning device, including a dust cup 20, an air intake pipe 31, a rotating pipe 32, a filter 30, a main body 10, and a sealing assembly of the cleaning device in Embodiment 1. The dust cup 20 includes an outer cylinder 21 and an inner cylinder 22 , and a primary dust area 200 is formed between the outer cylinder 21 and the inner cylinder 22 .

[0051] The intake pipe 31 is on the same axis as the main body 10 . Dust is guided from the intake duct 31 into the cleaning device. A rotating pipe 32 is integrally formed or fixedly connected with the intake pipe 31 , preferably, the inside of the rotating pipe 32 is a spiral pipe. The intake duct 31 guides the dust air to the swirling duct 32 for swirling.

[0052] The rotating pipe 32 is provided with an inner wall and an outer wall. The inner wall is helical. External air flows into the spiral pipe formed by the inner w...

Abstract

The invention provides a sealing assembly of a cleaning device. The sealing assembly comprises a first sealing piece and a second sealing piece. The first sealing piece is located on the edge of an inner cylinder of a dust cup to form a blocking structure for preventing outside air from entering a first-stage dust area of the dust cup. When the cleaning device works, the second sealing piece is located between the first-stage dust area and the second-stage dust area to form a blocking structure of the first-stage dust area and the second-stage dust area. After the dust cup is installed, that is, the cleaning device is in a dust collection state, the first sealing piece isolates the outside from the first-stage dust area, and in the process that the air inlet pipeline guides dust, unfiltered dust gas is prevented from entering the first-stage dust area to influence the dust collection effect; when the cleaning device is in a dust collection state, the second sealing piece separates the second-stage dust area in the rotating pipeline from the first-stage dust area in the dust cup, so that unfiltered dust is prevented from entering the main body part from the second-stage dust area, and the dust collection effect is prevented from being influenced by disordered streaming of gas during dust collection. The invention further provides a cleaning device.

Description

【Technical field】 [0001] The invention relates to the technical field of cleaning devices, in particular to a sealing assembly of a cleaning device and a cleaning device. 【Background technique】 [0002] In the prior art, the vacuum cleaner uses a motor to generate negative air pressure in a sealed casing, and sucks dust-containing air under the action of the pressure difference. In common hand-held vacuum cleaners, the dust collector or dust cup is generally installed next to the air inlet. The dust collection container or dust cup can store the dust filtered by the vacuum cleaner, but most of the dust cups on the market are directly set on the air intake pipe, or are located on the side of the air intake pipe, and are directly or indirectly connected with the air intake pipe. When the dust cup is removed, dust can easily enter the air intake duct, and when the air intake duct is vacuumed, outside air enters the dust cup, which affects the entry of dust into the dust cup. ...
