Abstract

A cleaning apparatus is provided. The cleaning apparatus includes a housing assembly having an exterior housing connected with a vacuum intake unit and an interior housing fixed to the exterior housing at a preset interval from an interior surface of the exterior housing. A brush assembly is disposed within the interior housing and is configured to rotate by a drive motor to contact a surface of a cleaning target. An air intake member has an air intake passageway that is connected with a cavity between the exterior housing and the interior housing and is slidably coupled to the housing assembly. A shock absorbing spring is mounted on the housing assembly and is configured to elastically supports the air intake member.

First claim

What is claimed is:

1. A cleaning apparatus, comprising:
a housing assembly having an exterior housing coupled to a vacuum intake unit, and an interior housing fixed to the exterior housing at a preset interval from an interior surface of the exterior housing;
a brush assembly disposed within the interior housing, and configured to rotate by a drive motor and contact a surface of a cleaning target;
an air intake member having an air intake passageway connected with a cavity between the exterior housing and the interior housing and slidably coupled to the housing assembly; and
a shock absorbing spring mounted on the housing assembly and configured to elastically support the air intake member.

2. The cleaning apparatus of claim 1 , wherein the exterior housing and the interior housing are fixed by a bolt and a nut.

3. The cleaning apparatus of claim 1 , wherein the brush assembly partially protrudes to the exterior of an air intake end of the air intake member.

4. The cleaning apparatus of claim 1 , wherein the shock absorbing spring is mounted at an outer circumference of the exterior housing.

5. The cleaning apparatus of claim 1 , wherein the exterior housing includes
a first portion which has an upper end that is opened and connected with the vacuum intake unit; and
a second portion integrally connected with a lower portion of the first portion, has an interior diameter greater than the first portion, and is opened at a lower end.

6. The cleaning apparatus of claim 5 , wherein the interior housing has a closed upper end and an opened lower end, and is disposed within the second portion through a lower end of the second portion.

7. The cleaning apparatus of claim 1 , wherein the drive motor is fixedly mounted within the interior housing by a mounting bracket.

8. The cleaning apparatus of claim 1 , wherein the brush assembly includes:
a brush body coupled to a driving shaft of the drive motor; and
brush bristles fixed to the brush body and partially protrude to the to the exterior of the air intake end of the air intake member.

9. The cleaning apparatus of claim 1 , wherein the air intake member includes:
an interior body is slidably coupled to the interior housing at an outer periphery of the brush assembly; and
an exterior body connected with the interior body, slidably coupled to the exterior housing, and having the air intake passageway formed between the exterior body and the interior body.

10. The cleaning apparatus of claim 9 , wherein the air intake passageway is a ring shape between the interior body and the exterior body.

11. The cleaning apparatus of claim 9 , wherein a plurality of stopping protrusions protrude upward from an upper end of the exterior body in an outer circumferential direction of the exterior housing, and the stopping protrusions are configured to be captured by a ring shaped stopper disposed on an outer circumferential surface of the exterior housing.

12. The cleaning apparatus of claim 11 , wherein the stopping protrusions penetrate the stopper, and a hook protrusion formed at an upper end of the stopping protrusion is configured to be captured by the stopper.

13. The cleaning apparatus of claim 9 , wherein a guide flange, is configured to guide intake air to the air intake passageway, and is formed at a lower end edge of the exterior body.

14. The cleaning apparatus of claim 13 , wherein the shock absorbing spring is mounted at an outer circumference of the exterior body and configured to elastically support the guide flange.

15. The cleaning apparatus of claim 11 , wherein a guide flange, is configured to guide intake air to the air intake passageway, and is formed at a lower end edge of the exterior body, wherein the shock absorbing spring is configured to support the stopper and the guide flange and is disposed at an outer circumference of the exterior body.

16. The cleaning apparatus of claim 1 , wherein a duct member, through which an electric wire connected to the drive motor is extended external to the exterior housing and external air as cooling air is introduced into the interior housing, is disposed in the interior housing.

17. The cleaning apparatus of claim 16 , wherein an air discharge aperture is formed in the interior housing, is connected with an interior of the exterior housing and discharges the cooling air.
