Description

Technical Field

[0001] This utility model relates to the field of DC brushless electric drills, specifically to a dustproof and waterproof DC brushless electric drill. Background Technology

[0002] Electric drills are the most commonly used power tools. They are convenient, inexpensive, and portable, and are highly praised by workers in the hardware and decoration industries. Workers can use electric drills to drill holes in various materials such as wood, metal, and cement walls, with wall drilling being the most common.

[0003] When drilling holes in a wall with an electric drill, the drill bit pulverizes the cement. The pulverized cement splashes as the drill bit rotates, and the splashing dust quickly fills the workspace, causing breathing difficulties for workers. Long-term inhalation of such dust can cause serious lung damage. At the same time, during the operation of the electric drill, particulate matter mixed in the dust may enter the worker's eyes, affecting their work and potentially causing more serious accidents.

[0007] To achieve dustproof installation, the dustproof installation assembly includes a dustproof installation fixing plate, which is connected to the main body of the DC brushless electric drill. The dustproof installation fixing plate has a sliding groove inside, and the dustproof installation fixing plate slides through the sliding groove to engage with a limit sliding rod. One end of the limit sliding rod is connected to a limit plate, and the end of the limit sliding rod away from the limit plate is connected to a moving ring. A dustproof cover is connected between the moving ring and the dustproof installation fixing plate, and a return spring is provided around the limit sliding rod.

[0008] Furthermore, the two ends of the return spring are connected to the dustproof mounting plate and the moving ring, respectively.

[0009] Furthermore, in order to achieve the function of dust filtration, the dust filtration assembly includes a suction pipe connected to a dustproof mounting plate. A dust filter box is provided on one side of the suction pipe, and a dust filter screen is installed inside the dust filter box. A sealing plate is sealed and attached to the top of the dust filter box, and a mounting plate is symmetrically connected to the outside of the dust filter box.

[0010] Furthermore, the sealing plate and the fixed mounting plate are connected by fixing bolts.

[0011] Furthermore, in order to achieve the function of vacuuming drive, the vacuuming drive assembly includes a vacuuming drive tube, one end of which is connected to a vacuuming fan, which is connected to the main body of the DC brushless electric drill, and the output end of the vacuuming fan is connected to an exhaust pipe.

[0012] Furthermore, the vacuum cleaner fan is electrically connected to an external power source via a switch.
