Abstract

The present invention relates to the technical field of manufacturing of small appliances, and relates to a glass-wiping robot. The glass-wiping robot comprises a robot main body, a power cord and a safety buckle. The power cord is connected to the robot main body, and winds onto the safety buckle. The safety buckle is provided thereon with a suction cup. The safety buckle sucks on a glass via the suction cup. The glass-wiping robot of the present invention provides double protection and improved safety effects when the robot main body inadvertently falls off the window, allows for convenient fixing or moving of the safety buckle, and is convenient to carry.

First claim

What is claimed is:

1. A glass-wiping robot comprising:
a robot main body,
a power cord connected to the robot main body and
a safety buckle wound by the power cord,
wherein:
the safety buckle is provided with a suction cup thereon for sucking the safety buckle onto a glass;
the safety buckle includes a first end face and a second end face connected by a central pillar; and
a stuck section is formed between the first end face and the second end face; and

wherein when the suction cup fails, the stuck section is stuck between the glass and a frame.

2. The glass-wiping robot of claim 1 , wherein at least one of the first face and the second end face is provided with a first threading hole and a second threading hole.

3. The glass-wiping robot of claim 2 , wherein the suction cup is provided at the first end face, and the power cord threads into the first threading hole of the second end face, and winds on the central pillar, and then threads out the second threading hole of the second end face.

4. The glass-wiping robot of claim 2 , wherein the suction cup is provided at the second end face, and the power cord threads into the first threading hole of the first end face, and winds on the central pillar, and then threads out the second threading hole of the first end face.

5. The glass-wiping robot of claim 2 , wherein the first threading hole and the second threading hole are axisymmetrically provided with respect to the central pillar.

6. The glass-wiping robot of claim 1 , wherein a through hole is provided at the center of the central pillar.

7. The glass-wiping robot of claim 1 , wherein in a glass cleaning, the robot main body is disposed at a first side of the glass, and the suction cup sucks on a second side of the glass; and wherein the first side of the glass is opposite to the second side of the glass.

8. The glass-wiping robot of claim 7 , wherein the first side of the glass is an outer side of the glass and the second side of the glass is an inner side of the glass.

9. A glass cleaning system, comprising,
a glass-wiping robot, and
a glass;
wherein:
the glass-wiping robot includes:
a robot main body,
a power cord connected to the robot main body, and
a safety buckle wound by the power cord,

the safety buckle is provided with a suction cup thereon for sucking the safety buckle onto a glass;
the safety buckle includes a first end face and a second end face connected by a central pillar;
a stuck section is formed between the first end face and the second end face, and
when the suction cup fails, the stuck section is stuck between the glass and a frame.

10. A glass cleaning method, wherein a glass-wiping robot includes a robot main body, a power cord connected to the robot main body and a safety buckle wound by the power cord, and wherein the safety buckle is provided with a suction cup thereon for sucking the safety buckle onto a glass,
the method comprising:
disposing the robot main body at a first side of the glass; and
sucking the suction cup on a second side of the glass;

wherein
the first side of the glass is opposite to the second side of the glass, such that the glass is prevented from being pushed open when the robot main body accidentally falls off the glass; and
when the suction cup fails, a stuck section formed between a first end face of the safety buckle and a second end face of the safety buckle is stuck between the glass of a frame, such that the glass-wiping robot is prevented from being damaged when the robot main body accidentally falls.
