Abstract

A dust removal device includes: an upper cover, a base, a support body, and a dust collector. The support body couples with the upper cover and the base. The dust collector includes: a first connecting member, a second connecting member, and a dust collecting body. The dust collecting body is coupled with the first connecting member and the second connecting member and has a folded structure. When an external force enables a shape of the first dust collecting body to be changed, a distance between the first connecting member and the second connecting member is also changed. In a cleaning mode, the dust collecting body is stretched and compressed in a reciprocating manner by using a structure of the dust collecting body.

First claim

What is claimed is:

1. A dust collector, comprising:
a first connecting member;
a second connecting member;
a first dust collecting body, coupled with the first connecting member and the second connecting member, and having a folded structure, wherein when an external force enables a shape of the first dust collecting body to be changed, a distance between the first connecting member and the second connecting member is also changed; and
a transmission unit coupled with one of the first connecting member and the second connecting member, and used to provide the external force, wherein when the transmission unit drives one of the first connecting member and the second connecting member so as to change the distance between the first connecting member and the second connecting member, the external force from the transmission unit also enables the shape of the first dust collecting body to be changed.

2. The dust collector of claim 1 , wherein at least one of the first connecting member and the second connecting member is a plate shape.

3. The dust collector of claim 1 , wherein the first dust collecting body is provided with at least one opening at two ends thereof.

4. The dust collector of claim 1 , wherein the folded structure comprises at least one traverse pleat vertical to a direction from the first connecting member to the second connecting member.

5. The dust collector of claim 4 , wherein the folded structure further comprises at least one non-traverse pleat used to absorb or release a stress change of a structural change of the first dust collecting body.

6. The dust collector of claim 4 , wherein the traverse pleat is coupled to a support frame, so as to retain a shape of the traverse pleat of the first dust collecting body.

7. The dust collector of claim 1 , wherein the first dust collecting body is a hollow structure.

8. The dust collector of claim 1 , wherein the first dust collecting body is selected from the group consisting of metal mesh, non-woven fabric, filter cloth, polytetrafluoroethylene, polypropylene fiber, polyester fiber, glass fiber, carbon fiber, activated carbon polyester fiber, and a combination thereof.

9. The dust collector of claim 1 , further comprising: a second dust collecting body coupled with the first dust collecting body.

10. The dust collector of claim 9 , further comprising: a third dust collecting body coupled with the first dust collecting body and the second dust collecting body.

11. A dust collector cleaning method, comprising the following steps of:
providing a dust collector, wherein the dust collector comprises:
a first connecting member;
a second connecting member; and
a first dust collecting body, coupled with the first connecting member and the second connecting member, and having a folded structure, wherein when an external force enables a shape of the first dust collecting body to be changed, a distance between the first connecting member and the second connecting member is also changed; and
entering a cleaning mode, wherein the folded structure is used to change the shape of the first dust collecting body, so as to clean dust adhered to the first dust collecting body.

12. The dust collector cleaning method of claim 11 , wherein the first dust collecting body is vibrated by changing the distance between the first connecting member and the second connecting member.

13. The dust collector cleaning method of claim 11 , wherein the first dust collecting body is vibrated by using a transmission unit.

14. The dust collector cleaning method of claim 11 , wherein at least one of a brush, an ultrasound source, a beating mechanism, pulse air stream, and water spray is used to assist to clean the dust adhered to the first dust collecting body.

15. A dust removal device, comprising:
an upper cover;
a base;
a support body, wherein the support body couples with the upper cover and the base; and
a dust collector, located between the upper cover and the base, and used to extract dust in air, wherein the dust collector comprises:
a first connecting member;
a second connecting member; and
a first dust collecting body, coupled with the first connecting member and the second connecting member, and having a folded structure, wherein when an external force enables a shape of the first dust collecting body to be changed, a distance between the first connecting member and the second connecting member is also changed;
wherein the dust removal device is applied to a dust collecting chamber, the dust collecting chamber comprises a dust collecting compartment and a sweeping element, and when the dust removal device enters the cleaning mode, the sweeping element sweeps the dust in the first dust collecting body to the dust collecting compartment, so as to collect the dust.
