Problems solved by technology

[0003] However, only filtering through the filter material such as Hypa will greatly reduce the service life of the filter material such as Hypa, because the dust will quickly cover the filter material such as Hypa, which will greatly reduce the filtering effect of the filter material, so frequent replacement is required The filter material is used to ensure the filtering effect, resulting in a higher replacement of the filter material

Embodiment 1

[0025] see Figure 1 to Figure 4 , this embodiment provides a dust cup separation structure for dust and gas, the dust cup body 1 is provided with an air inlet 11 and an air outlet 12, and the feature is that the first filter member 2 is detachably installed on the air outlet 12 , the second filter component 3 and the third filter component 4, the first cavity 13 is formed between the first filter component 2 and the dust cup body 1, and the second cavity 13 is formed between the second filter component 3 and the first filter component 2 21. The third cavity 31 is formed between the third filter component 4 and the second filter component 3, and the fourth cavity 41 is formed inside the third filter component 4, and the air mixed with dust passes through the air inlet 11, the first The cavity 13, the second cavity 21, the third cavity 31, and the fourth cavity 41 leave from the air outlet 12. The second filter component 3 is provided with a second filter passage 32, and the th...

Embodiment 2

[0032] see Figure 1 to Figure 4 , the figure shows a dust-gas separation structure of a dust cup provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements: Embodiment 1 The third filter channel 42 is located at 7 millimeters below the second filter channel 32, part of the air with dust will settle after passing through the second filter channel 32, and a part will be blocked on the outer wall of the third filter member 4, And some will enter the third filter channel 42 in the process of settling, and the filtering effect is not ideal enough.

[0033] In view of the above problems, the third filter channel 42 is arranged above the second filter channel 32, so that the settled dust cannot enter the third filter channel 42, which further improves the filtering effect.

Embodiment 3

[0035] see Figure 1 to Figure 4 , the figure shows a dust-gas separation structure of a dust cup provided by the third embodiment of the present invention. This embodiment has further made the following technical solutions as improvements on the basis of the above-mentioned embodiments: the first filtering The component 2 is provided with a first filter channel 22, the air in the first cavity 13 enters the second cavity 21 through the first filter channel 22, the first filter channel 22 is located below the second filter channel 32, and the second filter component 3 is provided with a dust isolation surface 33 that is bent inward, and the dust isolation surface 33 is located between the first filter channel 22 and the second filter channel 32. In the first embodiment, the dust isolation surface 33 is explained. The dust isolation surface 33 plays the role of blocking dust. In fact, if the dust isolation surface 33 is a smooth surface, it is difficult to retain dust, and some ...

Abstract

The invention provides a dust-air separation structure of a dust cup. According to the invention, a dust cup body is provided with an air inlet and an air outlet, the dust-air separation structure is characterized in that a first filtering part, a second filtering part and a third filtering part are detachably mounted on the air outlet; a first cavity is formed between the first filtering part and the dust cup body; a second cavity is formed between the second filtering part and the first filtering part; a third cavity is formed between the third filtering part and the second filtering part; a fourth cavity is formed in the third filtering part; air mixed with dust leaves from the air outlet after sequentially passing through the air inlet, the first cavity, the second cavity, the third cavity and the fourth cavity; the second filtering part is provided with a second filtering channel; the third filtering part is provided with a third filtering channel; and the third filtering channel is located below the second filtering channel. Compared with the prior art, the dust-air separation structure of the invention has the advantages that separation efficiency of dust in the air is improved, the adhesion rate of the dust on HEPA filter paper is reduced, the filtering effect of the HEPA filter paper is improved, and the service life of the HEPA filter paper is prolonged.

Description

technical field [0001] The invention relates to a dust cup, in particular to a dust-gas separation structure of the dust cup. Background technique [0002] The dust cup filter is to separate garbage and gas through the high-speed rotating vacuum airflow of the motor. Using the different density of air and dust, under the action of centrifugal force, the dust is thrown into the dust collection bucket, and the clean air is discharged, and then passes through filter materials such as Haipa. Purify the air to avoid secondary pollution. [0003] However, only filtering through the filter material such as Hypa will greatly reduce the service life of the filter material such as Hypa, because the dust will quickly cover the filter material such as Hypa, which will greatly reduce the filtering effect of the filter material, so frequent replacement is required The filter material is used to ensure the filtering effect, resulting in a higher replacement of the filter material.
