[0002] In the field of power tools, especially in outdoor working environments such as construction, garden maintenance, and road sweeping, the equipment often encounters severe challenges of high dust, high humidity, and strong vibration. However, in such environments, dust and particles often penetrate the power tool housing and come into contact with the switch, which can easily lead to poor contact, shortened life, or even functional failure, posing serious challenges to the reliable operation of the equipment.

[0003] Although traditional switches have certain dust-proof designs, they often only rely on simple sealing structures and cannot effectively deal with continuously accumulated dust pollution. After long-term use, they need to be disassembled and cleaned regularly, which increases maintenance costs and equipment downtime.

DETAILED DESCRIPTION

[0028] like Figures 1 to 6 As shown, a dustproof brushless switch comprises a housing 1, an electrical component 2, a pressing assembly 3, a corrugated sleeve 4, a spring 5, a mounting plate 6 and a rapping assembly 7.

[0029] The material of the corrugated sleeve 4 is elastic rubber material.

[0030] Furthermore, the shell 1 includes a first shell 101 and a second shell 102. The first shell 101 and the second shell 102 are connected by countersunk screws. A sealing gasket 103 is provided between the first shell 101 and the second shell 102. By installing the sealing gasket 103, the gap between the first shell 101 and the second shell 102 is sealed to prevent dust from entering the interior of both.

[0031] Furthermore, a through groove is formed on the first shell 101 , a first ring 104 is fixedly formed on the first shell 101 , and a mounting groove is formed inside the first shell 101 .

[0032] Furthermore, the electrical component 2 is connected to a pressing component 3 , and a switch action inside the electrical component 2 is triggered by the pressing component 3 .

[0033] Furthermore, the pressing assembly 3 includes a pressing block 301, on which a second ring 302 and a transmission block 303 are installed. The transmission block 303 is slidably arranged in the through groove, and a rubber block 304 is installed at the bottom of the transmission block 303. The rubber block 304 absorbs vibrations and impacts transmitted to the switch body or the mounting panel during the pressing operation, and is also used to absorb the vibrations generated by the rapping assembly 7 to prevent the vibrations generated by it from causing damage to the electrical components 2.

[0034] Furthermore, one end of the bellows 4 is mounted on the first ring 104, and the other end is mounted on the second ring 302. One end of the spring 5 is mounted on the pressing block 301, and the other end is mounted on the first shell 101, which serves as a seal between the transmission block 303 and the first shell 101 to prevent dust from entering through the gap between the two.

[0035] Furthermore, the spring 5 is located inside the bellows sleeve 4 , one end of which is mounted on the pressing block 301 , and the other end of which is mounted on the first housing 101 , and is used for resetting the pressing assembly 3 and stretching the bellows sleeve 4 .

[0036] Furthermore, the rapping assembly 7 includes a gear 701, a rack 702, a cam 703 and a rapping plate 704. The rack 702 is mounted on the transmission block 303 and meshes with the gear 701. A connecting rod 705 is installed at the axis of the gear 701. Positioning blocks 706 are rotatably provided at both ends of the connecting rod 705. The positioning blocks 706 are installed in the first shell 101. The cam 703 is installed on the connecting rod 705. The rapping plate 704 is installed in the first shell 101, and the movement of the pressing block 301 is linked to rap the shell 1 to clean the dust attached to the outside of the shell 1.

[0037] Specifically, there are two rapping plates 704 , which are distributed above and below the cam 703 and are symmetrically installed on the connecting rod 705 . There are several cams 703 , which are distributed on the connecting rod 705 in an array.

[0038] Furthermore, a vibration isolation pad 601 is installed on the mounting plate 6, and the vibration isolation pad 601 is connected to the electrical component 2. A clamping block 602 is fixedly provided at the bottom of the mounting plate 6, and the clamping block 602 is clamped in the mounting groove. The clamping connection between the clamping block 602 and the mounting groove facilitates the disassembly and assembly of the mounting plate 6. The mounting plate 6 is further fixed by installing the first shell 101 and the second shell 102. The electrical component 2 is isolated from vibration by installing the vibration isolation pad 601.

[0039] A dustproof brushless switch, the working principle is as follows:

[0040] When in use, the pressing block 301 is operated to drive the transmission block 303 to move, and the movement of the transmission block 303 drives the rubber block 304 to press the electrical component 2 to open or close it;

[0041] When the pressing block 301 moves, it squeezes the spring 5. When the transmission block 303 moves, it drives the rack 702 to move, driving the gear 701 meshing with it to rotate. The gear 701 drives the connecting rod 705 to rotate under the limit of the positioning block 706. The connecting rod 705 synchronously drives the cam 703 to move, so that the cam 703 contacts the rapping plate 704 for rapping. When the pressing block 301 is released, under the reaction force of the spring 5, the pressing block 301 is driven to reset, driving the pressing block 301 to reset, driving the gear 701 to reverse, driving the cam 703 to contact another rapping plate 704, and rapping is performed again.
