[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a drilling dust collection device, comprising a collecting box 1, an inlet 7 is opened at the center position of one end of the collecting box 1, a fixing pipe 4 is fixedly arranged at the center position of the other end of the collecting box 1, a handle 5 is screwed on the bottom end of the collecting box 1, a cavity is arranged inside the handle 5, a dustproof net 9 is fixedly arranged at the bottom of the cavity, a fan 10 is fixedly arranged at the bottom of the dustproof net 9, the cavity is connected with the interior of the collecting box 1 through the fan 10 and the dustproof net 9, the top end of the dustproof net 9 is in a conical shape, which is convenient for collecting dust and debris into the interior of the handle 5 and preventing the debris from causing harm to the user; the conical dustproof net 9 is convenient for concentrating the dust to both sides, thereby facilitating the discharge of air inside the cavity.

[0022] In this embodiment, a rubber ring 2 is fixedly provided on the outer wall of the collection box 1 corresponding to the outer side of the inlet 7, and a circular air hole 6 is opened inside the inner wall of the rubber ring 2, and the air hole 6 is connected with the inlet 7. A fixing plate 8 is fixedly installed between the other end of the fixing tube 4 and the top wall of the collection box 1, and the fixing plate 8 is fixedly provided inside the collection box 1. The central axes of the fixing tube 4 and the inlet 7 are on the same straight line, and the inner wall of the fixing tube 4 is a smooth inner wall. The collection box 1 is fitted with the wall or plate through the rubber ring 2 to avoid scratching the wall and plate, and air can enter the inside of the collection box 1 and the handle 5 through the air hole 6, so as to facilitate the collection of dust and debris generated by drilling; the fixing tube 4 can limit the drill bit to ensure the stability of the drill bit during drilling.

[0023] In this embodiment, an external thread 12 is provided on the outer side of the top end of the handle 5, and an internal thread 11 is provided on the inner wall of the bottom end of the collection box 1. The external thread 12 and the internal thread 11 are screwed together, and the handle 5 is convenient to disassemble through the internal thread 11 and the external thread 12, thereby facilitating the cleaning of dust and debris inside the handle 5.

[0024] In this embodiment, a battery box 3 is fixedly provided on the top of the collection box 1, and a battery is provided inside the battery box 3. The battery is electrically connected to the fan 10 through wires. The battery can power the fan 10, thereby facilitating the subsequent collection of dust and debris.

[0025] When using the drilling dust collection device, a switch is installed on the wire between the battery and the fan 10, and the fan 10 is started and stopped by the switch. The handle 5 is screwed and installed on the bottom of the collection box 1 through the external thread 12 and the internal thread 11. The fan 10 is powered by the battery. The drill bit of the drilling tool is inserted into the interior of the fixed tube 4 and passes through the inlet 7 and the inside of the rubber ring 2, and one end of the drill bit is brought into contact with the drilling position. The device is moved so that it contacts the wall or the plate through the rubber ring 2. The drill bit can be limited by the fixed tube 4 to prevent the drill bit from tilting. The fan 10 is started by the switch. When the fan 10 is working, the air in the cavity and the collection box 1 can be blown out from the handle 5. The bottom is discharged, so that negative pressure is generated inside the collection box 1 and the cavity. Since the air hole 6 is arranged inside the rubber ring 2, the outside air can enter the interior of the collection box 1 through the rubber ring 2 and the air hole 6. The debris generated by the drill bit drilling enters the collection box 1 and the interior of the cavity under the action of the airflow, and is blocked in the cavity by the dustproof net 9, so that the dust and debris generated by the drilling can be completely collected by the collection box 1 and the handle 5, avoiding the dust and debris from splashing around, and preventing the debris from causing harm to the user, which is highly practical. After the drilling is completed, the handle 5 is rotated and the handle 5 is disassembled through the external thread 12 and the internal thread 11, so that the dust and debris inside the handle 5 can be cleaned conveniently.
