Abstract

The present disclosure relates to a cleaner improving the cleaning efficiency. The cleaner includes a main body, a suction device configured to suck foreign substances on a surface to be cleaned, and an extension member positioned in the rear of the suction device to connect the main body and the suction device, wherein the suction device includes a suction head including a suction port, a connection member connecting the suction head and the extension member, and a weight accommodated in the suction device and disposed between the suction port and the extension member such that the suction port is prevented from being lifted from the surface to be cleaned when the suction device moves along the surface to be cleaned.

First claim

The invention claimed is:

1. A cleaner comprising:
a main body;
a suction device configured to suck foreign substances on a surface to be cleaned; and
an extension member connecting the main body and the suction device, to be positioned in the rear of the suction device,
wherein the suction device includes
a suction head including a suction port,
a connection member connecting the suction head and the extension member, and
a weight accommodated in the suction device and disposed between the suction port and the extension member at the rear of the suction port such that the suction port is prevented from being lifted from the surface to be cleaned when the suction device moves along the surface to be cleaned and wherein the connection member includes: a first connection member connected to the suction head, a second connection member connected to the extension member, and a first rotation shaft configured to rotatably connect the first connection member and the second connection member.

2. The cleaner according to claim 1 , wherein the weight is disposed between the suction port and the first rotation shaft.

3. The cleaner according to claim 1 ,
wherein the first connection member includes a second rotation shaft configured to rotatably connect the first connection member and the suction head, and
wherein the weight is disposed between the suction port and the second rotation shaft.

4. The cleaner according to claim 1 ,
wherein the suction head includes a lower case provided with the suction port and an upper case coupled to an upper portion of the lower case, and
wherein the weight is disposed in an inner space formed by the lower case and the upper case.

5. The cleaner according to claim 4 ,
wherein the suction head further includes a frame provided between the upper case and the lower case, and
wherein the weight is disposed between the frame and the lower case.

6. The cleaner according to claim 1 , wherein the weight includes a cylindrical shape.

7. The cleaner according to claim 1 , wherein the transverse length of the weight is greater than half the transverse length of the suction head.

8. The cleaner according to claim 1 , wherein the weight is disposed to form bilateral symmetry inside the suction device.

9. The cleaner according to claim 5 , wherein the suction device further includes a fixing member configured to fix the weight.

10. The cleaner according to claim 9 , wherein the fixing member includes a first fixing member disposed to prevent the movement of the weight in the left and right directions, and a second fixing member disposed to prevent the movement of the weight in the up and down directions.

11. The cleaner according to claim 10 , wherein the fixing member further includes a third fixing member disposed to prevent the movement of the weight in the front and rear directions.

12. The cleaner according to claim 11 ,
wherein the frame includes a frame body, and a holder configured at a lower portion of the frame body to fix a friction member for floating foreign substances on the surface to be cleaned, and
wherein the first fixing member and the third fixing member are configured in the lower case.

13. The cleaner according to claim 12 , wherein the second fixing member is configured in the holder.

14. The cleaner according to claim 12 , wherein the weight is disposed between the holder and the lower case.
