Description

Technical Field

[0001] This utility model relates to the technical field of robot vacuum cleaner accessories, specifically a quick-change structure for the side brush of a robot vacuum cleaner. Background Technology

[0002] A robotic vacuum cleaner, also known as a lazy person's vacuum cleaner, is a smart home appliance that can automatically vacuum the floor. Because it can detect factors such as room size, furniture placement, and floor cleanliness, and rely on its built-in program to plan a reasonable cleaning route, it has a certain degree of intelligence, hence the name "robot".

[0003] Robotic vacuum cleaners are equipped with side brush motors, and the side brushes are mounted on the motor's shaft. The side brushes are located at the bottom of the robot vacuum cleaner, near the outer edge, and have bristles. These bristles are consumable parts and need to be replaced after a period of use due to severe wear. Currently, the bristles and side brush are integrated, and the side brush is typically fixed to the motor's shaft with screws. This means that replacing the side brush requires first removing the screws with tools, which is cumbersome and hinders quick replacement.

[0004] Therefore, we propose a quick-change structure for the side brushes of robotic vacuum cleaners. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0018] 1. This utility model, by setting a connecting hole, a positioning hole, a positioning block, a slider, a spring, a button, a groove, a guide groove, and a guide block, allows for easy installation of the side brush assembly. First, press the button to move the slider upwards within the connector head. Simultaneously, the spring is compressed. With the cooperation of the guide groove and the guide block, the slider causes the positioning block to retract into the groove. Then, simply place the connecting plate onto the connector head from the lower end of the side brush motor shaft and release the button. When the connector head is fully inserted into the connecting hole, the spring automatically extends, pushing the slider downwards within the connector head. With the cooperation of the guide groove and the guide block, the slider causes the positioning block to insert into the positioning hole, thus fixing the connecting plate to the connector head.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1-4The robotic vacuum cleaner has a quick-change side brush structure, which includes a side brush motor shaft 1 and a side brush assembly 2. The end of the side brush motor shaft 1 is fixedly connected to a connector 11. The side brush assembly 2 includes a connecting plate 21 that fits into the connector 11 and multiple bristles 22 that are detachably connected around the connecting plate 21. By setting the side brush assembly 2, the side brush motor shaft 1 can be started to drive the connector 11 to rotate, which in turn drives the connecting plate 21 to rotate, and the connecting plate 21 drives the bristles 22 to perform cleaning.

[0030] Specifically, the connecting plate 21 has a connecting hole 23 in the middle that matches the connector 11. Multiple annularly distributed positioning holes 24 are formed on the inner wall of the connecting hole 23. Multiple annularly distributed positioning blocks 12 are slidably mounted on the outer wall of the connector 11. A slider 13 is slidably mounted inside the connector 11. A spring 14 abuts against the upper end of the slider 13, and a button 15 is fixedly connected to the lower end of the slider 13. Grooves 16 are formed on both sides of the slider 13, and guide grooves 17 are formed on the inner wall of the grooves 16. A guide block 18 that slides and engages with the guide groove 17 is fixedly connected to one end of each positioning block 12. By setting up the connecting hole 23, positioning holes 24, positioning blocks 12, slider 13, spring 14, button 15, grooves 16, guide grooves 17, and guide blocks 18, when installing the side brush assembly 2, the button 15 is pressed first, causing the button 15 to move the slider... Block 13 slides upward within connector 11, while spring 14 is compressed. Under the cooperation of guide groove 17 and guide block 18, slider 13 will drive positioning block 12 to retract into groove 16. Then, simply place connecting plate 21 from the lower end of side brush motor shaft 1 onto connector 11 and release button 15. When connector 11 is fully inserted into connecting hole 23, spring 14 will automatically extend, pushing slider 13 to slide downward within connector 11. Under the cooperation of guide groove 17 and guide block 18, slider 13 will drive positioning block 12 to insert into positioning hole 24, thus fixing connecting plate 21 to connector 11. When the side brush needs to be replaced, simply press button 15 to retract positioning block 12 into groove 16, and connecting plate 21 can be removed from connector 11 without the need for screws, facilitating quick replacement of side brushes.

[0031] The connector 11 has a guide block 19 on its outer wall and a guide groove 25 that matches the guide block 19 on the inner wall of the connection hole 23. By setting the guide block 19 and the guide groove 25, the connector 11 can be correctly guided when it is inserted into the connection hole 23, thus increasing the ease of installation.

[0032] Among them, a limiting protrusion ring 110 is provided on the outer wall of the connector 11 near the side brush motor shaft 1, and a limiting groove 26 adapted to the limiting protrusion ring 110 is provided at one end of the connecting hole 23. By setting the limiting protrusion ring 110 and the limiting groove 26, when the connector 11 is fully inserted into the connecting hole 23, the limiting protrusion ring 110 will be inserted into the limiting groove 26 to limit the connecting plate 21.

[0033] The connector 11 has a receiving groove 111 at its bottom, and the button 15 is embedded in the receiving groove 111. By setting the receiving groove 111, the button 15 can be accommodated and prevented from protruding to the outside and being bumped.

[0034] Furthermore, the bristles 22 are fixedly connected to the rod body 221. One end of the rod body 221 is provided with a T-shaped block 222. A T-shaped groove 27 adapted to the T-shaped block 222 is opened around the connecting plate 21. The positioning hole 24 passes through the T-shaped groove 27. A positioning groove 223 adapted to the positioning block 12 is opened on one side of the T-shaped block 222. By setting the T-shaped groove 27, the T-shaped block 222 and the positioning groove 223, when the side brush assembly 2 is removed from the side brush motor shaft 1, the T-shaped block 222 can slide out from the top of the T-shaped groove 27, so that a bristle 22 can be replaced individually, reducing maintenance costs. When the connecting plate 21 is connected to the connector 11, the positioning block 12 will pass through the positioning hole 24 and insert into the positioning groove 223, which can fix the rod body 221 at the same time, making it convenient for the bristles 22 to be disassembled and assembled.

[0035] The positioning block 12 is provided with an angle facing the opening of the T-slot 27. By providing the angle, when the T-block 222 slides into the T-slot 27, the angle of the positioning block 12 will automatically retract into the groove 16 after contacting the T-block 222, so that the T-block 222 can be inserted into the T-slot 27.

[0036] In practical use, the working principle of this utility model is as follows:

[0037] First, when installing the side brush assembly 2, press and hold button 15 to make button 15 drive slider 13 to slide upward in connector 11. At the same time, spring 14 is compressed. Under the cooperation of guide groove 17 and guide block 18, slider 13 will drive positioning block 12 to retract into groove 16. Then, simply put connecting plate 21 from the lower end of side brush motor shaft 1 onto connector 11 and release button 15. When connector 11 is fully inserted into connecting hole 23, spring 14 will automatically extend and push slider 13 to slide downward in connector 11. Under the cooperation of guide groove 17 and guide block 18, slider 13 will drive positioning block 12 to insert into positioning hole 24, thus fixing connecting plate 21 to connector 11. When connecting plate 21 is connected to connector 11, positioning block 12 will pass through positioning hole 24 and insert into positioning groove 223, which can simultaneously fix rod 221.

[0038] When the side brush needs to be replaced, simply press button 15 to retract the positioning block 12 into the groove 16, and the connecting plate 21 can be removed from the connector 11 without the need for screws, making it easy to quickly replace the side brush.

[0039] After the side brush assembly 2 is removed from the side brush motor shaft 1, the sliding T-block 222 slides out from the top of the T-slot 27, allowing individual brush bristles 22 to be replaced.

[0040] In summary, the quick-change structure for the side brush of this robotic vacuum cleaner, through the use of connector 11, eliminates the need for screws, facilitating the rapid replacement of the side brush.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
