Abstract

A cleaner and a vertical cleaner are provided. The cleaner includes: a body having a connecting tube; a brush holder, with a rolling brush mounted therein; a motor cover rotatably mounted onto the brush holder around a first axis, defining an accommodating space therein, and having an opening, the connecting tube being configured to connect to the opening rotatably around a second axis different from the first axis; a motor disposed in the accommodating space for driving the rolling brush to rotate relative to the brush holder around a third axis parallel to the first axis.

First claim

What is claimed is:

1. A cleaner, comprising:
a body having a connecting tube;
a brush holder, with a rolling brush mounted therein;
a motor cover rotatably mounted onto the brush holder around a first axis, defining an accommodating space therein, and having an opening, the connecting tube being configured to connect to the opening rotatably around a second axis different from the first axis and exposed to air, wherein an opening tube is extended outwardly from the opening of the motor cover, and a lower end of the connecting tube is rotatably connected within the opening tube;
a collar removably fitted over the opening tube, and having a protrusion which is protruded inwardly on an inner surface thereof, the protrusion being passed through the opening tube and matched with an annular groove in an outer surface of the connecting tube, a depression corresponding to the protrusion being formed in an outer surface of the collar;
a motor disposed in the accommodating space and configured to drive the rolling brush to rotate relative to the brush holder around a third axis parallel to the first axis.

2. The cleaner according to claim 1 , wherein the first axis is perpendicular to the second axis.

3. The cleaner according to claim 1 , wherein the brush holder has a mounting portion at a side thereof away from the rolling brush, and a boss is provided at each of two axial ends of the motor cover and rotatably mounted in the mounting portion.

4. The cleaner according to claim 3 , wherein the mounting portion is configured as a first semicircular groove, and the boss is configured as a cylindrical boss.

5. The cleaner according to claim 4 , further comprising:
a fixing member defining two ends each having a second semicircular groove, the second semicircular groove being matched with the first semicircular groove to define a circular accommodating hole for accommodating the boss.

6. The cleaner according to claim 5 , wherein the fixing member surrounds a part of the motor cover and comprises:
a connecting plate having a length extended in an axial direction of a shaft of the motor;
two fixing plates connected to two ends of the connecting plate respectively, the second semicircular grooves being formed at free ends of the two fixing plates respectively.

7. The cleaner according to claim 5 , wherein a snap groove is formed in an upper end of the fixing member, and a snap tongue matched with the snap groove is provided on the body or the connecting tube.

8. The cleaner according to claim 1 , wherein a rotation angle of the motor cover around the first axis relative to the brush holder ranges from 0 to 90 degrees.

9. The cleaner according to claim 1 , wherein the shaft of the motor is extended out from a side of the motor cover, and drives the rolling brush to rotate via a belt.

10. The cleaner according to claim 9 , wherein the brush holder defines a chamber therein, the rolling brush and the belt are located in the chamber, and the shaft of the motor is extended into the chamber.

11. The cleaner according to claim 1 , wherein the matching between the protrusion and the annular groove is configured in such a way that the connecting tube is rotated through 0 to 180 degrees relative to the opening tube.

12. A vertical cleaner, comprising:
a body having a connecting tube at a lower end thereof, the connecting tube being exposed to air;
a brush holder located at a lower portion of the body, a rolling brush being mounted at a front end of the brush holder;
a motor cover rotatably mounted onto an end of the brush holder away from the rolling brush, and defining an accommodating space therein, an opening tube communicated with the accommodating space being provided on the motor cover, a lower end of the connecting tube being rotatably connected within the opening tube;
a collar removably fitted over the opening tube, and having a protrusion which is protruded inwardly on an inner surface thereof, the protrusion being passed through the opening tube and matched with an annular groove in an outer surface of the connecting tube, a depression corresponding to the protrusion being formed in an outer surface of the collar;
a motor disposed in the accommodating space, a shaft of the motor being extended out from a side of the motor cover and driving the rolling brush to rotate relative to the brush holder via a belt.

13. The vertical cleaner according to claim 12 , wherein the connecting tube is rotated through 0 to 180 degrees relative to the opening tube.
