Detailed Description

The technical solution in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

The embodiment of the utility model provides a limit brush assembly devices, it can be known to refer to fig. 1 to 4, and this limit brush assembly devices cooperation limit brush subassembly 103 sets up the drain pan at cleaning machines people, and this limit brush assembly devices includes that an up end and drain pan place plane become the first screw post 105 of predetermineeing the angle, and the central pivot barrel casing of limit brush subassembly 103 can use the screw to fix its inclination state on screw post 105. Since the upper end surface of the screw post 105 forms a first predetermined angle with the plane of the bottom case, the side brush assembly 103 is assembled to the bottom case and also forms a first predetermined angle with the plane of the bottom case. Specifically, the side brush assembly 103 includes a brush cover, a brush holder of a strip-shaped brush, and bristles, the bristles are uniformly and neatly distributed around the circumference of the brush holder, and are inclined and spread in a tapered direction along the side of the brush holder after the bristles are inserted, as shown in fig. 3, the side brush bristles 101 on the left side of the bottom case and the side brush bristles 102 on the right side of the bottom case, and the brush cover is designed to be directly inserted into the bristles 101 and 102 in an inclined state.

As shown in fig. 2 and 4, in the direction from the rear end of the bottom case to the front end thereof, the central rotation shaft of the side brush assembly 103 of the sleeve on the lead screw 105 is inclined forward by a second preset angle with respect to the body center line of the cleaning robot; as shown in fig. 3, the central rotation axis of the side brush assembly 103 of the stud upper sleeve is inclined to the left and right sides of the bottom case by a third preset angle with respect to the central line of the body of the cleaning robot in the direction from the inner side of the bottom case to the left and right sides thereof, respectively. The side brush assembly mechanism is used for obliquely assembling a side brush assembly 103, as shown in fig. 3, the side brush bristles 101 on the left side of the bottom shell and the side brush bristles 102 on the right side of the bottom shell are tightly attached to the ground at one side of the part on the outer side of the bottom shell, and the part on the inner side of the bottom shell is lifted away from the ground to be cleaned. Compared with the prior art, the embodiment of the utility model provides an avoid limit brush subassembly 103 to take the rubbish of cleaning originally the dust absorption mouth position department of the main brush 104 of drain pan to the organism outside, improve and clean efficiency, reinforcing user experience.

Preferably, the first preset angle is controlled between 3 and 8 degrees, in the embodiment of the present invention, the upper end face of the screw column 105 and the inclination angle of the plane where the bottom casing is located are controlled to be about 7 degrees, so that the side brush assembly 103 also follows the inclination of 7 degrees. In the course of the work of limit brush subassembly 103, the brush hair that realizes the limit brush utilizes the unilateral power of exerting oneself of inclination to effectively clean ground, for prior art, the embodiment of the utility model provides an avoid the limit brush that does not contain the angle can only push away debris or dust, can not effectively sweep debris or dust into the dust absorption mouth of main brush 104.

Preferably, the side brush is required to achieve the best working effect, the front-back inclination angle and the left-right inclination angle of the side brush are important influencing factors, and in the case of the side brush, the front inclination angle of the side brush is 4.71 degrees and the inner inclination angle of the side brush is 5.2 degrees to achieve the best cleaning effect. As shown in fig. 2, the second preset angle is set to 4.71 degrees, and the side brush assembly 103 is inclined upwards from the rear end of the bottom shell along the direction of the front end of the bottom shell and is inclined 4.71 degrees with the central line of the machine; meanwhile, as shown in fig. 3, the third preset angle is set to 5.2 degrees, and the side brush assembly 103 is inclined downwards from the inner side of the bottom case along the directions of both sides of the bottom case and forms an inclination angle of 5.2 degrees with the center line of the machine; under the embodiment of the present invention, the bristles of the side brush assembly 103 on the outside of the machine tightly contact the ground, such as the side brush bristles 101 on the left side of the bottom case and the side brush bristles 102 on the right side of the bottom case in fig. 3, and the side brush bristles on the outside of the machine tightly contact the ground. Due to the second preset angle and the third preset angle, when the side brush assembly 103 rotates around the central rotating shaft thereof, the bristles 101 and 102 can carry the garbage outside the machine to the position of the dust suction port of the main brush 104 inside the machine during the rotation process, so that the bristles of the side brush rotating inside the machine can be lifted off the ground, the garbage swept to the middle can be prevented from being ejected again, and then the dust can be collected in the dust collection box through the rotation of the main brush 104 and the suction force formed by the fan. Thereby improving the cleaning efficiency and the cleaning effect.

It should be noted that the side brush assembling mechanisms are arranged on the left side and the right side in front of the bottom shell, so that the cleaning range is improved. The side brush assembling mechanism is also used for assembling a multi-stage gear to establish the connection relation between the side brush assembly and the driving motor. Specifically, the side brush assembling mechanism is a side brush device powered by a power source motor, and includes: the central rotating shaft of the side brush main body is arranged in the side brush lower cover, and the bearing is arranged in the side brush lower cover to ensure that the side brush main body does not rotate in an abrasion way. The side brush bristles 101 on the left side of the bottom shell and the side brush bristles 102 on the right side of the bottom shell are fixed on the side brush assembly 103 through buckles. The side brush assembly is gear driven by the side-sweeping motor teeth, the side-sweeping secondary teeth and the side-sweeping tertiary teeth. After the host computer starts, the side-sweeping motor is driven to rotate by a PCBA (printed Circuit Board Assembly) of the host computer, and the side-brushing bristles 101 on the left side of the bottom shell and the side-brushing bristles 102 on the right side of the bottom shell are driven to rotate according to the directions shown in figure 1 through gear driving, so that the overall working performance of the machine is improved.

A bottom shell is assembled with the side brush assembling mechanism, and the inclined design of the side brush assembly 103 on the left side and the inclined design of the side brush assembly 103 on the right side are used, so that the side brush bristles 101 on the left side of the bottom shell and the side brush bristles 102 on the right side of the bottom shell are tightly attached to the ground when the bottom shell is arranged on the outer side of a machine body, and are lifted off the ground when the bottom shell is rotated to the.

The utility model provides a cleaning machines people, this cleaning machines people assembles above-mentioned drain pan, makes the brush hair on the limit brush subassembly of assembly on the drain pan can not sweep out the position rubbish of sweeping the cleaning machines people centre originally, has improved and has cleaned efficiency, reinforcing user experience.
