How to improve deep cleaning capabilities has become a challenge for the entire industry. Reducing noise and improving self-cleaning effects are also pain points in the industry.
[0033] The main technical problem solved by the present invention is to realize the real-time live water floor washing function on the robot and achieve deep cleaning of the ground environment.
[0034] In order to solve the above technical problems, a technical solution adopted by the present invention is: using a double-drum structure, the two drums contact the ground at the same time to improve the cleaning effect of floor scrubbing, and at the same time offset the influence of rolling friction on robot control. There is a ground spring structure above the drum bracket 2, and the weight of the drum assembly 1 is balanced by springs of different lengths to increase the pressure on the ground. Through the scraper structure with springs, dynamic pressure can be applied to the drum to enhance the self-cleaning effect of the drum. Due to the elastic characteristics of the spring, the life of the drum mop is also extended, reducing the frequency of users replacing the drum.
[0035] In the embodiments of the present application, compared with the prior art that "the drum part cannot perform deep cleaning on the ground, the force on the ground cannot be controlled, and the cleaning effect is poor", the present application provides a solution of "a spring structure on the drum bracket 2 is provided to balance the weight of the drum assembly 1 and increase the pressure on the ground through springs of different lengths", specifically: a drum assembly 1, a drum bracket 2 and a bracket spring assembly 3;
[0036] The bottom of the roller bracket 2 wraps the roller assembly 1, and the top of the roller bracket 2 is connected to the bracket spring assembly 3; the roller assembly 1 includes at least two rollers; the bottom of the roller bracket 2 is provided with a semi-cylindrical groove for wrapping the roller assembly 1; wherein, the number of the semi-cylindrical grooves is the same as the number of the rollers. The bracket spring assembly 3 solves the problem that "the roller part cannot perform deep cleaning on the ground, the force on the ground cannot be controlled, and the cleaning effect is poor". The use of a double-roller structure, the two rollers contact the ground at the same time to improve the cleaning effect of the floor washing, and at the same time offset the influence of rolling friction on the robot control. There is a ground bracket spring assembly above the roller bracket 2, and the weight of the roller assembly 1 is balanced by springs of different lengths to increase the pressure on the ground. Through the scraper structure with a spring, dynamic pressure can be applied to the roller to enhance the self-cleaning effect of the roller. Due to the elastic characteristics of the spring, the life of the roller mop is also extended, reducing the frequency of users replacing the roller.
[0037] Reference Figure 1-3 , shows a schematic structural diagram of the roller structure of the utility model, which may specifically include the following structures: a roller assembly 1, a roller bracket 2 and a bracket spring assembly 3; the bottom of the roller bracket 2 wraps the roller assembly 1, and the top of the roller bracket 2 is connected to the bracket spring assembly 3; the roller assembly 1 includes at least two rollers; a semi-cylindrical groove is provided at the bottom of the roller bracket 2 for wrapping the roller assembly 1; wherein the number of the semi-cylindrical grooves is the same as the number of the rollers.
[0038] Next, a drum structure in this exemplary embodiment will be further described.
[0039] In one embodiment of the present application, the support spring assembly 3 includes a first support spring 31 and a second support spring 32; the first support spring 31 and the second support spring 32 are symmetrically arranged; the length of the second support spring 32 is smaller than the length of the second support spring 32; the second support spring 32 is arranged close to the drum rotation motor 4, and the first support spring 31 is arranged away from the drum rotation motor 4.
[0040] In a specific embodiment, the first bracket spring 31 and the second bracket spring 32 are both used to increase the pressure of the drum on the ground when it is working, so that the drum is cleaner when cleaning; when the drum rotating motor 4 is arranged between the first bracket spring 31 and the second bracket spring 32, the first bracket spring 31 and the second bracket spring 32 have the same length. When the drum rotating motor 4 is next to the second bracket spring 32, in order to balance the weight, the length of the second bracket spring 32 is less than the length of the second bracket spring 32. The first bracket spring 31 and the second bracket spring 32 are respectively arranged above the drum bracket 2, so that the force can be evenly transmitted to the drum assembly 1. Due to the elasticity of the spring, the life of the drum mop is also extended, and the frequency of replacing the drum by the user is reduced.
[0041] In one embodiment of the present application, a drum rotating motor 4 for controlling the rotation of the drum is further provided on the top of the drum bracket 2 ; the drum rotating motor 4 is electrically connected to the drum assembly 1 .
[0042] In a specific embodiment, there is a support spring for ground pressure above the drum support 2, and both support springs are perpendicular to the ground. The weight of the drum assembly 1 is balanced by springs of different lengths. Since the gravity at the end where the drum rotating motor 4 is installed is large, the second support spring 32 is shorter than the first support spring 31.

[0048] In a specific embodiment, the bottom of the roller bracket 2 half wraps the roller assembly 1, and the semi-cylindrical groove at the bottom of the roller bracket 2 is adapted to the roller, and the size of the semi-cylindrical groove is slightly larger than the first roller 11 and the second roller 12.
[0049] In one embodiment of the present application, the roller assembly 1 includes at least two rollers; the roller assembly 1 includes a first roller 11 and a second roller 12; the first roller 11 and the second roller 12 are arranged in parallel, and the first roller 11 and the second roller 12 rotate in opposite directions.
[0050] In a specific embodiment, the first roller 11 and the second roller 12 are respectively connected to the roller bracket 2 through a middle connecting rod, so that the first roller 11 and the second roller 12 can rotate. Using a double-roller structure, the two rollers contact the ground at the same time to improve the cleaning effect of the floor scrubbing, while offsetting the influence of rolling friction on the control of the robot.
[0051] In one embodiment of the present application, the outer ring of the first drum 11 and the outer ring of the second drum 12 are both wrapped with a drum mop.
