Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and particularly relates to an underwater cleaner. Background Art

[0002] Underwater cleaners are used to replace manual labor to clean various pools. For example, pool robots can clean the bottom and side walls of the pool and filter the water in the pool. During the working process, such underwater cleaners are driven by motors to move, enabling the underwater cleaners to move on various surfaces of the pool. Pollutants on the pool surface are further cleaned by a rotary brush, and the water in the pool is filtered by sucking in water, filtering the water, and then discharging the water.

[0003] Most of the current underwater cleaners achieve the effect of cleaning while moving by meshing the motor and the rotary brush with the inside of the traveling mechanism respectively. However, this structure has high requirements for processing accuracy and installation, and it is also not convenient to adjust the position of the rotary brush. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome these disadvantages and provide an underwater cleaner for cleaning immersed surfaces (such as swimming pools, reservoirs, landscape pools, etc.). The underwater cleaner has a cleaning device, especially a cleaning rotary brush, which has the advantages of adjustable position and adjustable speed.

[0005] The utility model provides such an underwater cleaner, comprising:

[0006] A main body, including a water inlet and a water outlet;

[0007] A pumping device configured to guide water flow from the water inlet to the water outlet;

[0008] Wheels configured to be rotatable and having internal gear rings;

[0009] A cleaning device, including a brush roller for cleaning and a rotary brush gear;

[0010] An intermediate gear set for connecting the rotary brush gear and the internal gear ring, so that the wheels rotate in a first direction and drive the rotary brush gear and the brush roller to also rotate in the first direction.

[0011] The beneficial effect of the utility model lies in that: the underwater cleaner provided by the utility model indirectly realizes the transmission between the rotary brush gear and the internal teeth of the belt wheel through an intermediate gear, which is convenient to adjust the position of the cleaning device through the rotary brush gear, and the number of teeth of the intermediate gear set can be adjusted according to actual needs to achieve different transmission ratios, so as to adapt to different application scenarios.
