Abstract

A cleaning device includes a bristle bundle and a handle. The handle has a tubular structure and includes a straight part and a bent part, and the bent part is located at the end of the straight part. The bristle bundle is detachably placed in the tubular structure of the handle, and one end of the bristle bundle extends out of the bent part.

First claim

What is claimed is:

1. A cleaning device, comprising a bristle bundle and a handle, wherein:
the handle has a tubular structure and comprises a straight part and a bent part, and the bent part is located at an end of the straight part; and
the bristle bundle is detachably placed in the tubular structure of the handle, and one end of the bristle bundle extends out of the bent part, wherein weak areas are arranged on the bristle bundle at a predetermined length, a bristle section is formed between adjacent weak areas, and a diameter of the weak areas is smaller than a diameter of the bristle section in a non-weak area, wherein a periphery of the bristle bundle is covered with an outer thin film, wherein a plurality of holes are arranged in positions, corresponding to the weak areas, on the outer thin film, wherein a plurality of spherical limiting protrusions are arranged on an outer wall of the outer thin film.

2. The cleaning device according to claim 1 , wherein:
the cleaning device further comprises a gelatinous cleaner; and
the gelatinous cleaner is placed in a cavity formed by an inner thin film and the bristle section, wherein the bristle bundle has a hollow tubular structure, and the inner thin film perpendicular to the bristle bundle is arranged corresponding to the weak areas in the hollow tubular structure of the bristle bundle.

3. The cleaning device according to claim 1 , wherein a plurality of one-way limiting buckles are arranged on an inner wall of the handle, and a direction to pass the one-way limiting buckles is from the straight part to the bent part.

4. The cleaning device according to claim 3 , wherein a cross sectional shape of the one-way limiting buckle is a right triangle, one right-angle side of the right triangle is on an inner wall of the handle, and the other right-angle side of the right triangle is closer to a tube orifice of the bent part than a hypotenuse of the right triangle.

5. The cleaning device according to claim 1 , wherein a strip-shaped opening is formed in a tube wall of the straight part at an end thereof opposite the bent part and which enables a force to be applied to an end of the bristle bundle.

6. The cleaning device according to claim 5 , wherein a number of the strip-shaped openings exist and the number is 2.

7. A method of manufacturing a cleaning device, comprising:
providing a bristle bundle and a handle for the cleaning device;
providing a tubular structure for the handle, wherein the tubular structure comprises a straight part and a bent part, and the bent part is located at an end of the straight part;
detachably placing the bristle bundle in the tubular structure of the handle, wherein one end of the bristle bundle extends out of the bent part;
providing weak areas that are arranged on the bristle bundle at a predetermined length; and forming a bristle section between adjacent weak areas, wherein a diameter of the weak areas is smaller than a diameter of the bristle section in a non-weak area; and
covering a periphery of the bristle bundle with an outer thin film, wherein a plurality of holes are arranged in positions, corresponding to the weak areas, on the outer thin film, wherein a plurality of spherical limiting protrusions are arranged on an outer wall of the outer thin film.

8. The method according to claim 7 , further comprising:
providing a gelatinous cleaner for the cleaning device, wherein the gelatinous cleaner is placed in a cavity formed by an inner thin film and the bristle section, wherein the bristle bundle has a hollow tubular structure, and the inner thin film perpendicular to the bristle bundle is arranged corresponding to the weak areas in the hollow tubular structure of the bristle bundle.

9. The method according to claim 7 , further comprising:
arranging a plurality of one-way limiting buckles on an inner wall of the handle, wherein a direction to pass the one-way limiting buckles is from the straight part to the bent part.

10. A cleaning device, comprising:
a bristle bundle and
a handle, wherein:
the handle has a tubular structure and comprises a straight part and a bent part, and the bent part is located at an end of the straight part; and
the bristle bundle is detachably placed in the tubular structure of the handle, and one end of the bristle bundle extends out of the bent part,
wherein a strip-shaped opening is formed in a tube wall of the straight part at an end thereof opposite the bent part and which enables a force to be applied to an end of the bristle bundle.

11. The cleaning device according to claim 10 , wherein weak areas are arranged on the bristle bundle at a predetermined length, a bristle section is formed between adjacent weak areas, and a diameter of the weak areas is smaller than a diameter of the bristle section in a non-weak area.

12. The cleaning device according to claim 11 , wherein:
the cleaning device further comprises a gelatinous cleaner; and
the gelatinous cleaner is placed in a cavity formed by an inner thin film and the bristle section, wherein the bristle bundle has a hollow tubular structure, and the inner thin film perpendicular to the bristle bundle is arranged corresponding to the weak areas in the hollow tubular structure of the bristle bundle.

13. The cleaning device according to claim 11 , wherein:
a periphery of the bristle bundle is covered with an outer thin film; and
a plurality of holes are arranged in positions, corresponding to the weak areas, on the outer thin film.

14. The cleaning device according to claim 13 , wherein a plurality of spherical limiting protrusions are arranged on an outer wall of the outer thin film.

15. The cleaning device according to claim 14 , wherein a plurality of one-way limiting buckles are arranged on an inner wall of the handle, and a direction to pass the one-way limiting buckles is from the straight part to the bent part.

16. The cleaning device according to claim 15 , wherein a cross sectional shape of the one-way limiting buckle is a right triangle, one right-angle side of the right triangle is on an inner wall of the handle, and the other right-angle side of the right triangle is closer to a tube orifice of the bent part than a hypotenuse of the right triangle.

17. The cleaning device according to claim 10 , wherein a number of the strip-shaped openings exist and the number is 2.

18. A method of manufacturing a cleaning device as defined in claim 10 , comprising:
providing a bristle bundle and a handle for the cleaning device;
providing a tubular structure for the handle, wherein the tubular structure comprises a straight part and a bent part, and the bent part is located at an end of the straight part;
detachably placing the bristle bundle in the tubular structure of the handle, wherein one end of the bristle bundle extends out of the bent part, and
forming a strip-shaped opening in a tube wall of the straight part at an end thereof opposite the bent part and which enables a force to be applied to an end of the bristle bundle.
