Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment and relates to a split roller brush of a water surface cleaning robot. Background Art

[0002] The water surface cleaning robot is a cleaning tool used for swimming pools and pools. The water surface cleaning robot can slide freely on the water surface through the propeller installed at the tail. During the sliding process, the roller brush at the front end will continue to roll, collecting the garbage encountered during the sliding process into the garbage basket inside the cleaning robot, thereby achieving the function of cleaning floating objects on the water surface.

[0003] In the patent number: CN219754162U, the structure of a water surface cleaning robot is disclosed, and its working principle is the same as the above-mentioned method. In the structure of this robot, the roller brush installed at the front end adopts an integrated structure, that is, each blade extends to both sides of the robot. This increases the length of a single blade and reduces the strength of the blade structure. It is easy to deform during use, and when the blade is damaged, the entire roller brush needs to be replaced, which increases the cost of using the water surface cleaning robot. Summary of the Invention

[0004] The purpose of the utility model is to address the problems existing in the existing technology and propose a split roller brush for a water surface cleaning robot. The technical problem to be solved by the utility model is: how to improve the structural strength of the roller brush.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a split roller brush of a water surface cleaning robot, comprising a roller, one end of which is provided with a key-connected gear, the roller is provided with a plurality of key-connected small roller brushes, and the small roller brushes are provided with a plurality of fixed blades.

[0006] In this solution, the gear is engaged with the motor on the cleaning robot, and the motor drives the roller to rotate. The rotating roller transmits the torque to several small roller brushes connected by keys, so that the blades on all small roller brushes rotate synchronously, thereby realizing the function of pushing the garbage at the front end of the cleaning robot into the interior of the robot. In the above manner, multiple small roller brushes are keyed to the roller. When one or more small roller brushes are deformed and damaged, the roller can be removed from the cleaning robot, and the small roller brush that needs to be replaced can be removed. The undamaged small roller brush can continue to be used, and a new small roller brush can be inserted. This solves the problem of the existing technology that the entire roller brush needs to be removed and replaced, reducing the cost of replacing the roller brush. At the same time, since the lateral length of the blade on a single small roller brush becomes shorter, the structural strength of the blade is higher, and it is not easy to be damaged and deformed, thereby increasing the service life of the roller brush.

[0007] In the aforementioned split roller brush of the water surface cleaning robot, one end of each small roller brush is provided with several fixed buckles. A single buckle is provided on either side of a blade, with the buckle facing away from the blade. The buckle engages with the blades of adjacent small roller brushes. The buckle is provided at one end of the small roller brush, connecting adjacent small roller brushes via the buckle, enabling synchronized rotation of the blades and more stable rotation of the small roller brushes.

[0008] In the aforementioned split roller brush of the water surface cleaning robot, the roller shaft is equipped with keyed end caps at both ends. The end caps, located on the side closest to the small roller brush, have slots equal in number to the blades, into which the blades are inserted. The roller shaft can simultaneously transmit torque to the end caps, which, through the slots, assist in the rotation of the small roller brush.

[0009] In the aforementioned split roller brush of the water surface cleaning robot, the roller shaft has limit slots at both ends, each containing a snap-on rubber gasket. The gasket at one end abuts against the gear, while the gasket at the other end abuts against the end cap. The gaskets abut against both ends of the roller shaft, preventing the small roller brush on the roller shaft from shifting.

[0010] In the aforementioned split roller brush of the water surface cleaning robot, the roller has a hexagonal cross-section, and the centers of the gear, small roller brush, and end cap are each provided with a keyway corresponding to the roller structure. While this embodiment employs a hexagonal structure for key connection, other embodiments can also be used to achieve a key connection between the roller brush and the roller.

[0011] In the split roller brush of the water surface cleaning robot, hinged bearings are provided on the outer side walls of the end caps at both ends. The inner side of the bearing is hinged to the end cap and the outer side is hinged to the cleaning robot, so that the bearing can rotate inside the cleaning robot.

[0012] In the aforementioned split roller brush of the water surface cleaning robot, the roller and the small roller brush are mounted on the front end of the cleaning robot and located at the opening of the waste basket inside the cleaning robot. The small roller brush rotates on the water surface cleaning robot and pushes the garbage at the front end of the cleaning robot into the waste basket inside the robot.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. In this solution, multiple small roller brushes are connected to the roller key. When one or more small roller brushes are deformed and damaged, the roller can be removed from the cleaning robot, and the small roller brushes that need to be replaced can be removed. The undamaged small roller brushes can continue to be used, and then a new small roller brush can be inserted. This solves the problem of the existing technology that the entire roller brush needs to be removed and replaced, thereby reducing the cost of replacing the roller brush.

[0015] 2. In this solution, since the transverse length of the blades on a single small roller brush is shortened, the structural strength of the blades is higher, and they are not easily damaged or deformed, thereby increasing the service life of the roller brush.

[0016] 3. In this solution, a buckle is provided at one end of the small roller brush, and the adjacent small roller brushes are connected by the buckle, so that the blades can rotate synchronously, and the rotation of the small roller brush can also be more stable.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] Example

[0023] like Figure 1 As shown, the split roller brush of the water surface cleaning robot includes a roller 1, on which are provided a number of key-connected small roller brushes 3, on the circumference of which are provided a number of fixed blades 3a, and the small roller brushes 3 are adjacently arranged on the roller 1, and the cross-section of the roller 1 is hexagonal.

[0024] like Figure 1 Combine Figure 2 As shown, key-connected end covers 4 are provided at both ends of the roller 1, and slots 4a are provided on one side of the end cover 4. The number of the slots 4a is the same as the number of the blades 3a, and the blades 3a are inserted into the slots 4a. The end cover 4 is snap-connected with the small roller brush 3, and a key-connected gear 2 is provided at the outermost end of the roller 1. Limiting grooves 1a are provided at both ends of the roller 1, and a snap-connected rubber gasket 1a1 is provided inside the limiting groove 1a. The gasket 1a1 at one end abuts against the gear 2, and the gasket 1a1 at the other end abuts against the end cover 4. Articulated bearings 5 are provided on the outer side walls of the end covers 4 at both ends.

[0025] like Figure 3As shown, one end of the small roller brush 3 is provided with a plurality of fixed buckles 3b, and the single buckle 3b is respectively provided on both sides of the blade 3a, and the buckle 3b is facing the end away from the blade 3a. The buckle 3b is connected with the blade 3a on the adjacent small roller brush 3 by snapping. The center of the gear 2, the small roller brush 3 and the end cover 4 are all provided with a key groove 6 corresponding to the structure of the roller 1.

[0026] The working principle of this scheme is as follows: Figure 1-3 As shown, the roller 1 is hingedly mounted on the front end of the cleaning robot through the bearing 5 on the end cover 4. The motor on the cleaning robot is engaged with the gear 2, and the motor drives the gear 2 to rotate. The gear 2 drives the key-connected roller 1 to rotate. The rotating roller 1 transmits the torque to several small roller brushes 3 connected by the key, so that the blades 3a on all the small roller brushes 3 rotate synchronously, thereby pushing the garbage at the front end of the cleaning robot into the storage basket set inside the robot.

[0027] In the above method, multiple small roller brushes 3 are keyed to the roller 1. When one or more small roller brushes 3 are deformed and damaged, the roller 1 can be removed from the cleaning robot, and the small roller brush 3 that needs to be replaced can be removed. The undamaged small roller brush 3 can continue to be used, and then a new small roller brush 3 can be inserted. This solves the problem of the need to remove and replace the entire roller brush in the prior art, reducing the cost of replacing the roller brush. At the same time, since the horizontal length of the blade 3a on a single small roller brush 3 becomes shorter, the structural strength of the blade 3a is higher, and it is not easy to be damaged and deformed, thereby increasing the service life of the roller brush.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0029] Although this document frequently uses terms such as 1. roller; 1a. limit groove; 1a1. gasket; 2. gear; 3. small roller brush; 3a. blade; 3b. buckle; 4. end cap; 4a. notch; 5. bearing; 6. keyway, the use of other terms is not excluded.
