[0029] Handheld vacuum cleaner is a small, portable dust collector, compared with the traditional vacuum cleaner, handheld vacuum cleaner has the advantages of small and portable, low noise, but because of its small structure, resulting in its dust collection bin capacity is small, in the process of long time dusting, dust collection bin is easy to be filled with dust and debris, users need to remove the dust collection bin several times to clean the dust in it, which brings inconvenience to the use.

[0030] In the scheme, the movable shell 4 and the fixed shell 2 form a closed space, the user starts the power supply inside the dust collector main body 1 to drive the impeller to rotate at high speed, which can generate negative pressure in the inside of the connecting plate 21 and the movable shell 4, and then the dust is sucked into the inside of the fixed shell 2 and the movable shell 4 through the dust collection pipe 3 for collection, the horizontal plate 41 and the vertical plate 42 are both made of transparent material, which is convenient for the user to observe the dust collection amount, during the dust collection process, once the dust is full, the user can rotate the annular knob 5 to make it gradually separate from the threaded rod 24, and then drive the movable shell 4 to move, so that the limiting block 43 slides in the limiting groove 25, with the vertical plate 42 away from the second side plate 23, the dust located between the pair of horizontal plates 41 will be intercepted by the second side plate 23, when the edge position of the lower horizontal plate 41 slides below the second side plate 23, the user gently shakes the dust collector main body 1 to make the dust intercepted by the second side plate 23 fall from the lower side of the fixed shell 2, so that the user can quickly remove the collected dust by simply pulling the movable shell 4, without complicated installation and removal work.

[0031] As shown in Figure 4 , 6 and 7, the inner wall of the limiting groove 25 is covered with a first sealing gasket 26, the first sealing gasket 26 is in close contact with the outer surface of the limiting block 43, one end of the pair of horizontal plates 41 away from the vertical plate 42 is covered with a third sealing gasket 44, the upper and lower sides of the inner end of the first side plate 22 are provided with a butt joint groove 28 matched with the horizontal plate 41 and the limiting block 43, the upper and lower ends of the second side plate 23 are covered with a second sealing gasket 27, and one end of the pair of horizontal plates 41 is in close contact with the pair of second sealing gaskets 27.

[0032] The third sealing gasket 44, the first sealing gasket 26 and the second sealing gasket 27 can be made of rubber, and are arranged to fill the gaps between the movable shell 4 and the fixed shell 2 after the movable shell 4 and the fixed shell 2 are combined, thereby improving the sealing of the movable shell 4 and the fixed shell 2 and enhancing the dust collection effect. The transverse plate 41 and the limiting block 43 can be embedded in the butt joint groove 28, so that the third sealing gasket 44 tightly abuts against the inner wall of the butt joint groove 28, and the tighter the ring-shaped knob 5 is screwed, the more tightly the movable shell 4 and the fixed shell 2 are combined.

[0033] As shown in Figure 5 , a filter screen 7 is arranged between the pair of connecting plates 21, and the second side plate 23 and the inner end of the threaded rod 24 are integrally formed with a positioning block 8 near the side of the dust collector main body 1. The two ends of the filter screen 7 are respectively clamped with a pair of positioning blocks 8, and the filter screen 7 covers the through hole.

[0034] In the present scheme, the filter screen 7 can effectively trap dust entering the inside of the fixed shell 2 and the movable shell 4, prevent it from entering the inside of the dust collector main body 1, and at the same time, will not hinder the passage of air flow. When the user opens the movable shell 4, the filter screen 7 can be distinguished from the pair of positioning blocks 8, so as to clean it at any time.

[0035] As shown in Figure 8 , the outer end of the connecting plate 21 near the dust collection pipe 3 is integrally formed with a connecting ring 6, the connecting ring 6 penetrates the connecting plate 21, and the dust collection pipe 3 is threadedly connected with the connecting ring 6.

[0036] In the present scheme, the user can rotate the dust collection pipe 3 to dismount it from the connecting ring 6, so as to clean the inside of the dust collection pipe 3 regularly.

[0037] Working principle:

[0038] When the dust collection work is carried out, the user starts the power inside the dust collector main body 1 to drive the impeller to rotate at high speed, that is, the connecting plate 21 and the inside of the movable shell 4 can generate negative pressure, and then the dust is sucked into the inside of the fixed shell 2 and the movable shell 4 through the dust collection pipe 3 to collect, once the dust is full, the user rotates the annular knob 5 to make it gradually separate from the threaded rod 24, and then drives the movable shell 4 to move, so that the limiting block 43 slides in the limiting groove 25, with the longitudinal plate 42 away from the second side plate 23, the dust between the pair of transverse plates 41 will be intercepted by the second side plate 23, when the edge position of the lower transverse plate 41 slides below the second side plate 23, the user shakes the dust collector main body 1 gently, so that the dust intercepted by the second side plate 23 falls from the lower side of the fixed shell 2, then the user pushes the movable shell 4 back, so that the threaded rod 24 passes into the annular knob 5 again, and the annular knob 5 is tightened, so that the fixed shell 2 and the movable shell 4 are closed again.

[0039] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
