[0025] The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0026] This embodiment relates to a circuit board dust removal device. In terms of the overall structure, as Figure 1 shown, it includes a protective cover 1, a handle 2, a driving mechanism 3, and a dust removal mechanism 4.

[0027] Among them, a support plate 101 is provided on one side of the bottom of the protective cover 1. The handle 2 is fixedly arranged on the top of the side of the protective cover 1 away from the support plate 101. The driving mechanism 3 is fixedly arranged inside the protective cover 1. The dust removal mechanism 4 is fixedly arranged at the bottom of the protective cover 1. The dust removal mechanism 4 includes an air extraction pump 401 fixedly arranged on the side of the support plate 101 away from the handle 2, a dust removal box 402 fixedly arranged at the bottom of the air extraction pump 401, and a cylinder body 403 fixedly arranged on the side of the support plate 101 close to the handle 2. The cylinder body 403 is connected to the air extraction pump 401 through a connecting pipe 404.

[0028] It is worth mentioning that the protective cover 1 adopts a square structure, which plays a role in protecting the driving mechanism 3. The support plate 101 is located on one side of the bottom of the protective cover 1 and is perpendicular to the protective cover 1, providing support for the installation of the dust removal device. The handle 2 is installed on the side of the protective cover 1 away from the support plate 101. The operator operates the dust removal device by holding the handle 2, making the dust removal device more convenient and flexible to use. The driving mechanism 3 is installed inside the protective cover 1. The air extraction pump 401 is installed on the side of the support plate 101 away from the handle 2. The cylinder body 403 is installed on the side of the support plate 101 close to the handle 2. The top of the air extraction pump 401 is communicated with the top of the cylinder body 403 through the connecting pipe 404. The air extraction pump 401 extracts the gas and dust in the cylinder body 403 through the connecting pipe 404, and makes the pressure inside the cylinder body 403 lower than the pressure outside the cylinder body 403. Under the action of the air extraction pump 401, the bottom of the cylinder body 403 is opened to communicate with the outside. The dust removal box 402 is connected and installed at the bottom of the air extraction pump 401. The air extraction pump 401 transports the gas extracted from the cylinder body 403 to the dust removal box 402, so as to clean the dust absorbed at the bottom of the cylinder body 403.

[0029] As an option, still as Figure 1 shown, in this embodiment, the driving mechanism 3 includes a carrier plate 301 fixedly arranged at the middle position of the protective cover 1, a motor 302 fixedly arranged on the carrier plate 301, and a speed reducer 303 fixedly arranged at the bottom of the motor 302. A rotating shaft 304 is rotatably arranged at the bottom of the speed reducer 303, and a brush 305 is fixedly arranged at the bottom of the rotating shaft 304.

[0030] It should be noted that the carrier plate 301 is fixedly arranged inside the protective cover 1, providing support for the installation of the motor 302 and the speed reducer 303. The motor 302 is installed on the top of the carrier plate 301, providing power for the driving mechanism 3. The speed reducer 303 is installed at the bottom of the carrier plate 301 and is connected to the motor 302. The rotating shaft 304 is rotatably installed at the bottom of the speed reducer 303. The speed reducer 303 transmits the high-frequency rotation provided by the motor 302 after speed reduction to the rotating shaft 304, making the rotation speed of the rotating shaft 304 easier to control. The brush 305 is installed at the bottom of the rotating shaft 304 and rotates with the rotating shaft 304, so that the brush 305 cleans the dust on the circuit board.

[0031] Preferably, as Figure 2 and Figure 3 shown, in this embodiment, a cylindrical through groove 4031 is provided through the bottom and top of the cylinder body 403. The inside of the cylinder body 403 is a hollow structure. A circular through groove 4032 is provided at the bottom of the cylinder body 403. A pressing mechanism 405 is fixedly provided at the inner bottom of the cylinder body 403. Four sliding grooves 4033 are equidistantly arranged on the side wall of the inner bottom of the cylinder body 403.

[0032] Specifically, the cylindrical through groove 4031 is opened on the central axis of the cylinder body 403. The cylinder body 403 is a hollow structure. A circular through groove 4032 is opened at the bottom of the cylinder body 403 to communicate the inside of the cylinder body 403 with the outside of the cylinder body 403. The pressing mechanism 405 is arranged inside the cylinder body 403 and is located at the top of the circular through groove 4032. When the dust removal device is in an unoperated state, the pressing mechanism 405 presses and seals the circular through groove 4032 to make the cylinder body 403 in a sealed state, preventing dust and other impurities from entering the cylinder body 403 and causing problems such as blockage. Four sliding grooves 4033 are opened on the side wall of the inner bottom of the cylinder body 403 to make the pressing mechanism 405 move more smoothly on the sliding grooves 4033.

[0033] Preferably, still as Figure 3 shown, in this embodiment, the pressing mechanism 405 includes a fixing plate 4051 fixedly provided at the bottom of the cylinder body 403, a limiting groove 4052 opened at the bottom of the fixing plate 4051, and a limiting column 4053 slidably arranged on the limiting groove 4052. A circular sealing plate 4054 is fixedly provided at the bottom of the limiting column 4053. A compression spring 4055 is arranged on the limiting column 4053. The two ends of the compression spring 4055 are respectively fixedly connected to the fixing plate 4051 and the circular sealing plate 4054. Four sliders 4056 are symmetrically arranged at equal intervals on the outer side of the circular sealing plate 4054. The circular sealing plate 4054 is arranged on the sliding grooves 4033 inside the cylinder body 403 through the sliders 4056. The circular sealing plate 4054 is arranged on the circular through groove 4032.

[0034] Specifically, there are four fixing plates 4051 on the pressing mechanism 405, which are arranged at equal intervals inside the cylinder body 403. The fixing plates 4051 are fixedly installed at the bottom inside the cylinder body 403, providing support for the movement of other components in the pressing mechanism 405 inside the cylinder body 403. A limiting groove 4052 is formed at the bottom of the fixing plate 4051, and the top of the limiting post 4053 is installed in the limiting groove 4052. The limiting post 4053 can move up and down in the limiting groove 4052. The annular sealing plate 4054 is fixedly installed at the bottom of the limiting post 4053 and is located on the annular through groove 4032 inside the cylinder body 403. The compression spring 4055 is installed around the limiting post 4053 to avoid deformation problems when the compression spring 4055 is compressed by an external force. The top and bottom of the compression spring 4055 are respectively connected to the bottom of the fixing plate 4051 and the top of the annular sealing plate 4054. Four sliders 4056 are arranged at equal intervals on the outer circumferential surface of the annular sealing plate 4054. The sliders 4056 are arranged on the sliding groove 4033 inside the cylinder body 403. When the dust removal device is working, under the action of the air extraction pump 401, the pressure inside the cylinder body 403 is much lower than the pressure outside the cylinder body 403. Under the action of the pressure difference, the air outside the cylinder body 403 pushes the annular sealing plate 4054 upward. At this time, the sliders 4056 on the annular sealing plate 4054 slide upward on the sliding groove 4033, making the inside of the cylinder body 403 communicate with the outside of the cylinder body 403. Since the pressure inside the cylinder body 403 is relatively low, the gas and dust at the bottom outside the cylinder body 403 are sucked into the cylinder body 403. And when the annular sealing plate 4054 moves upward, the limiting post 4053 moves upward in the limiting groove 4052. At the same time, the compression spring 4055 between the annular sealing plate 4054 and the fixing plate 4051 is compressed. When the dust removal device stops working, under the action of the compression spring 4055, the annular sealing plate 4054 moves downward to press and seal the annular through groove 4032 at the bottom of the cylinder body 403.

[0035] Preferably, still as Figure 2 shown, in this embodiment, the rotating shaft 304 is arranged through the cylindrical through groove 4031 of the cylinder body 403, and the brush 305 is arranged at the bottom of the cylinder body 403. Specifically, the rotating shaft 304 is installed through the cylindrical through groove 4031 inside the cylinder body 403, and the diameter of the rotating shaft 304 is smaller than the diameter of the cylindrical through groove 4031, reducing the friction between the rotating shaft 304 and the cylinder body 403 during rotation. The brush 305 is installed at the bottom of the rotating shaft 304 and is located at the bottom of the cylinder body 403. When performing dust removal work, while the brush 305 cleans the dust, the bottom of the cylinder body 403 sucks the dust into the cylinder body 403 through the annular through groove 4032, avoiding the dust flying everywhere when cleaning the circuit board and affecting the environment and the health of the staff.

[0036] Preferably, still as Figure 1As shown in the figure, in this embodiment, a fixing clip 5 is provided on the side of the support plate 101 close to the handle 2, and the cylinder body 403 is installed on the support plate 101 through the fixing clip 5. Specifically, the fixing clip 5 is installed on the support plate 101 and is divided into upper and lower parts to clamp and fix the cylinder body 403, ensuring the stability of the cylinder body 403 when the dust removal device is in use.

[0037] For the circuit board dust removal device of the present utility model, through the setting of the handle 2, it is ensured that the dust removal device is easier to operate. Through the combined setting of the driving mechanism 3 and the dust removal mechanism 4, it is ensured that while the dust on the surface of the circuit board is cleaned, the dust can be adsorbed and transferred to the dust removal box 402 through the dust removal mechanism 4, avoiding the problem of dust flying when the circuit board is being cleaned.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
