Abstract

A self-moving dust suction device comprises a body, at least one buffer means and a sticking means. The body includes a top cover, a base, a dust suction operation module, at least two movement wheels and at least one mounting portion. The buffer means is corresponding to the mounting portion and has an installation dock fastened to the mounting portion, a buffer element located on the installation dock to provide an action force in a direction remote from the top cover in normal conditions and a butting dock located at one end of the buffer element remote from the top cover to bear the action force. The sticking means is located at one side of the base and has a connection bracket coupled with the butting dock to receive the action force transmitted by the butting dock and a sticking roller located on the connection bracket.

Claims

1. A self-moving dust suction device, comprising:

a body including a top cover, a base coupled with the top cover to jointly form a housing space, a dust suction operation module located on the base and held in the housing space, at least two movement wheels located on the base and driven by the dust suction operation module and at least one mounting portion located at one side of the base remote from the top cover;

at least one buffer means which corresponds to the mounting portion and includes an installation dock fastened to the mounting portion, a buffer element located on the installation dock to provide an action force in normal conditions in a direction remote from the top cover, and a butting dock located at one end of the buffer element remote from the top cover to bear the action force in the normal conditions; and

a sticking means which is located at one side of the body corresponding to the base and includes a connection bracket coupled on the butting dock to receive the action force transmitted by the butting dock and a sticking roller located on the connection bracket.

2. The self-moving dust suction device of claim 1, wherein the base comprises a first assembly portion abutting the mounting portion for fastening of the installation dock.

3. The self-moving dust suction device of claim 1, wherein the installation dock includes a seat, an assembly space formed on the seat for assembly of the buffer element and a second assembly portion at one edge of the seat corresponding to the first assembly portion for installation thereof.

4. The self-moving dust suction device of claim 3, wherein the butting dock includes a baseboard corresponding to the installation dock in contact with the buffer element to receive the action force in the normal conditions and an assembly strut located on the baseboard and extended toward the installation dock to couple with the buffer element and confine the butting dock on the installation dock to be movable up and down thereof.

5. The self-moving dust suction device of claim 3, wherein the installation dock includes a track located on the seat and communicating with the assembly space, the butting dock including a rib corresponding to the track to confine movement amplitude of the butting dock.

6. The self-moving dust suction device of claim 3, wherein the connection bracket includes a rack for assembly of the sticking roller and at least one installation portion located on the rack and faced the base to couple with the installation dock.

7. The self-moving dust suction device of claim 6, wherein the rack includes a connection portion for installation of the sticking roller and a dust barrier extended from the connection portion to partially cover the sticking roller.

8. The self-moving dust suction device of claim 6, wherein the installation portion includes at least two spaced assembly walls which jointly form a buffer gap.

9. The self-moving dust suction device of claim 7, wherein the assembly space has an inner diameter, and the installation portion has an outer diameter greater than the inner diameter.

10. The self-moving dust suction device of claim 7, wherein the body is a circular disk.

11. The self-moving dust suction device of claim 1, wherein the buffer means comprises a fastener fastened to the installation dock.

12. The self-moving dust suction device of claim 11, wherein the fastener is a screw.
