Description

Technical Field

[0001] The utility model relates to the technical field of sweeping robots, in particular to an anti-collision sweeping robot. Background Art

[0002] A robot vacuum, also known as a lazy sweeper, is a smart home appliance that automatically vacuums the floor. It's called a robot because it can detect factors like room size, furniture placement, and floor cleanliness, and uses built-in programming to develop a reasonable cleaning route. This intelligence gives it the name "robot."

[0003] When traditional sweeping robots moved in the past, because the front end was not equipped with an anti-collision silicone pad, when the top colliding with an obstacle, although there was contact detection and avoidance, the plastic shell of the sweeping robot would still cause abrasions or scratches on the leather or paint of the furniture, affecting the appearance of the leather or paint of the swept furniture or the sweeping robot, reducing the service life and increasing the subsequent maintenance costs. In addition, the sweeping robot will rub against the ground during the cleaning process, which is prone to generate static electricity. This static electricity not only affects the normal operation of the machine, but may also cause dust to be adsorbed on the body, affecting the cleaning effect, and there is also the risk of damage to internal electronic components. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides an anti-collision sweeping robot, which has advantages such as anti-collision and solves the problems raised in the background art.

[0005] To achieve the above-mentioned anti-collision purpose, the present invention provides the following technical solution: an anti-collision sweeping robot, comprising a sweeping robot body, a dust sweeping opening provided at the middle of the bottom end of the sweeping robot body, two sweeping wheels provided inside the dust sweeping opening, and four rollers provided outside the bottom end of the sweeping robot body;

[0006] A silicone pad is provided on the upper part of the front end wall of the sweeping robot body. The inner layer material of the silicone pad is a silicone layer. The outer layer of the silicone layer is provided with an elastic layer. Multiple groups of rubber balls are distributed inside the elastic layer. The outer layer of the elastic layer is provided with an anti-scratch film. The anti-scratch film, elastic layer and silicone layer are connected in sequence by mucus.

[0007] As a further solution of the present invention: the anti-scratch film is made of a high-strength polyethylene film, which can improve the strength of the surface of the sweeping robot body and avoid scratches.

[0008] As a further solution of the present invention: an anti-static film is provided at the bottom of the sweeping robot body. The anti-static film at the bottom of the sweeping robot body prevents the generation and accumulation of static electricity, thereby reducing dust adsorption on the body and improving the cleaning effect, while protecting the internal electronic components of the sweeping robot body and extending the life of the equipment.

[0009] As a further solution of the present invention: a plurality of recesses are provided on the front upper end of the sweeping robot body and the upper part of the front end wall, and there are seven recesses in total. Seven protrusions are provided on the inner side wall of the silicone pad, and the protrusions are arranged at corresponding positions with the recesses. By pulling the protrusions out of the recesses, the silicone pad can be disassembled for easy cleaning and replacement.

[0010] As a further solution of the present invention: a plurality of anti-skid particles are provided on the surface of the roller, which increases the friction between the roller and the ground, prevents the sweeping robot body from slipping when moving, and improves stability.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, the front part of the robot vacuum cleaner body is protected by a silicone pad to prevent the plastic shell of the robot vacuum cleaner from contacting the leather or paint of the furniture, which may cause abrasions or scratches on the contact surface, affecting the leather or paint of the furniture or the appearance of the robot vacuum cleaner; the anti-scratch film is made of high-strength polyethylene film, which can improve the strength and smoothness of the surface of the robot vacuum cleaner body and reduce the scratches on the contact surface. The elastic layer will be squeezed when the silicone pad is squeezed, and the rubber ball will produce elastic deformation, thereby providing buffering. The protrusion will be pulled out of the recess, and the silicone pad can be disassembled for easy cleaning and replacement, avoiding damage to internal components caused by collision, thereby increasing service life and reducing later maintenance costs.

[0013] 2. In the present invention, the antistatic film at the bottom of the robot vacuum cleaner body prevents the generation and accumulation of static electricity, which can not only reduce the adsorption of dust on the body and improve the cleaning effect, but also protect the internal electronic components of the robot vacuum cleaner body and extend the life of the equipment.
