[0022] In order to enable the user to measure the weight of the user through the cleaning robot 1, in this embodiment, preferably, the weighing zone 7 measures the weight of the weighed person through the pressure sensor 9, and the measurement result is displayed on the display screen 6.

[0023] In order to enable the cleaning robot 1 to obtain sufficient power, in this embodiment, preferably, two driving wheels 24 are provided, and the two driving wheels 24 are both installed on the lower surface of the cleaning robot 1.

[0024] In order to enable the driving wheel 24 to rotate better, in this embodiment, preferably, the driving wheel 24 and the driving motor 26 are rotatably connected through the driving shaft 25, and the driving wheel 24 drives the universal wheel 14 to rotate to control the cleaning robot 1 move.

[0025] In order to enable the roller brush 22 to better clean the dust on the ground, in this embodiment, preferably, the roller brush 22 and the roller brush motor 23 are rotatably connected through the rotating shaft 21, and the dust cleaned by the roller brush 22 is vacuumed. The port 18 is adsorbed and stored in the ash storage tank 20.

[0026] In order to enable the elastic sleeve 31 to reduce the wear of the cleaning robot 1 after a collision, in this embodiment, preferably, two elastic sleeves 31 are provided, and the two elastic sleeves 31 are both installed on the outer frame 2, and the elastic sleeve The bouncing ball 30 inside 31 will impact the spring 33 after the cleaning robot 1 collides with a hard object.

[0027] In order to enable the dusting brush 28 to gather the dust on both sides of the cleaning circuit on the inside of the chassis 10 of the cleaning robot 1, so that the roller brush 22 can collect the dust. In this embodiment, preferably, there are two dusting brushes 28. , And two dust-removing brushes 28 are installed on the lower surface of the cleaning robot 1. The dust-removing brush 28 can disperse dirt on the ground, so that the roller brush 22 can clean the dust.

[0028] In order to enable the distance sensor 11 to move according to a set route, in this embodiment, preferably, there are two distance sensors 11 in total, and the two distance sensors 11 are both installed on the lower surface of the cleaning robot 1.

[0029] In order to enable the cleaning robot 1 to withstand the impact caused by the impact and reduce the damage to the cleaning robot 1 caused by the impact, in this embodiment, preferably, the cleaning robot 1 and the outer frame 2 are fixedly connected by bolts, and the inside of the outer frame 2 A plurality of elastic balls 30 are provided on the ball storage ring 29.

[0030] The distance sensor in the present invention converts the mechanical displacement into a resistance or voltage output in a linear or arbitrary function relationship with the potentiometer element. The displacement of the object causes the resistance of the moving end of the distance sensor to change, and the change in resistance value reflects the displacement The increase or decrease of the resistance value indicates the direction of displacement. Usually, the power supply voltage is applied to the distance sensor to convert the resistance change into a voltage output.

[0031] The working principle and application process of the present invention: After the present invention is installed, the start switch 4 is turned on, the cleaning robot 1 cleans on a preset route, the cleaning robot 1 detects the path through the distance sensor 11, and the drive motor 36 passes through the drive shaft 25 Drive the driving wheel 24 to rotate to provide the power required for the movement of the cleaning robot 1. The driving wheel 24 cooperates with the universal wheel 14 to complete the movement of the cleaning robot 1, and the ash-raising brush 28 collects dust and dirt on the cleaning path when the cleaning robot 1 moves. Under the chassis 10, the rolling brush motor drives the rolling brush 22 to rotate through the rotating shaft 21 to clean dust and dirt. The cleaned dust is collected inside the ash storage tank 20 through the vacuum suction port 18. When the cleaning robot 1 is moving, it is received In an external impact, the elastic sleeve 31 on the outer frame 2 initially buffers the impact force brought about by the impact. The impact force after the buffering drives the elastic ball 30 to move in the ball storage ring 29, and most of the impact force is transmitted to the outside world. The impact force is eliminated under the contraction of the damping pad 32 and the spring 33, which reduces the impact of the impact on the cleaning robot 1, improves the operation stability of the cleaning robot 1, and increases the service life of the cleaning robot 1. The user stands in the weighing area The weight can be measured by the pressure sensor 9 on the 7 and the measured value is displayed on the display 6. After use, turn off the start switch 4, clean the dust in the ash storage tank 20, and use the charging patch 15 to control the battery tank 16 The battery inside is charged.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
