Device for removing by suction drill dust when drilling holes into walls

1. A device for removing drill dust when drilling a hole into a wall, wherein the device comprises:

a base member;

at least one vacuum chamber provided in the base member;

at least one suction site;

a connecting socket connected to the base member and adapted to connect a vacuum unit that removes by suction at the suction site the drill dust produced by drilling;

wherein the at least one suction site and the at least one vacuum chamber are spatially separated from one another;

wherein the at least one vacuum chamber has at least one opening connecting fluidically the at least one vacuum chamber to the connecting socket;

wherein the connecting socket has a partition dividing the connecting socket and defining a vacuum passage in which drill dust is conveyed, wherein the partition separates the at least one opening from the vacuum passage;

wherein the at least one vacuum chamber has a chamber wall provided with at least one relief opening connecting the vacuum chamber to the ambient;

a guide bushing for a drill bit, wherein the at least one suction site is delimited by the guide bushing.

2. The device according to claim 1 , further comprising a suction sleeve, wherein the guide bushing is inserted into the suction sleeve.

3. The device according to claim 2 , wherein the guide bushing is fixedly secured in the suction sleeve.

4. The device according to claim 2 , wherein the suction sleeve and the guide bushing are exchangeable for accommodating differently sized drill bits.

5. The device according to claim 2 , wherein the connecting socket adjoins the suction sleeve.

6. The device according to claim 5 , wherein the connecting socket is positioned at an acute angle relative to an axis of the suction sleeve.

7. The device according to claim 5 , wherein the guide bushing and the suction sleeve have a through opening connecting the suction site with the connecting socket.

8. The device according to claim 7 , wherein the through opening extends in a circumferential direction of the guide bushing and the suction sleeve.

9. The device according to claim 5 , further comprising a coupling member connected to the connecting socket.

10. The device according to claim 9 , wherein the coupling member is an angle member.

11. The device according to claim 10 , wherein the angle member is rotatably arranged in the connecting socket.

12. The device according to claim 9 , wherein the angle member has a first part and a second part and wherein axes of the first and second parts intersect at a point of intersection, wherein the point of intersection is spaced, when viewed in a plan view onto the device, from a rearward end of the base member located opposite the suction site.

13. The device according to claim 9 , wherein the angle member has a first part and a second part and wherein axes of the first and second parts intersect at a point of intersection, wherein the point of intersection has no spacing, when viewed in a plan view onto the device, relative to a rearward end of the base member located opposite the suction site.

14. The device according to claim 5 , wherein a wall of the a least one vacuum chamber, the suction sleeve, and the connecting socket together form a monolithic part.
