Description

Technical Field

[0001] The utility model relates to the technical field of electronic component dust removal, in particular to a dust removal device for cleaning electronic components. Background Art

[0002] At present, computers absorb dust in the air during use, affecting the normal heat dissipation of the computer equipment. The computer will automatically restart or shut down due to overheating protection. When the dust accumulates to a certain level, it will be adsorbed on the circuit board to form charged dust, causing a short circuit or even burning the computer equipment. Therefore, it is necessary to regularly remove dust from the computer equipment to ensure normal heat dissipation of the computer equipment so that the computer equipment can work normally.

[0003] During the cleaning process, general dust removal devices not only cannot emit air, but also the dust in the dust removal chamber easily falls from the dust suction port during the dust removal process, making it impossible to completely remove the dust. The dust removal efficiency is not good, and the installation spacing between the brushes cannot be adjusted according to the arrangement density of electronic components, and cannot meet people's usage needs well.

[0004] In order to solve the above problems, after searching the existing public patent (application number: CN201821440655.0), an electronic component dust removal device is proposed in the article. It "includes a main body shell, a micro motor and a connecting ring, a lifting handle is provided on the top of the main body shell, a fixing ring is provided inside the main body shell, a fan blade is fixed to the left end of the micro motor, a dust storage bin is provided on the right side of the fixing ring, a connecting groove is provided at the right end of the main body shell, a filter is installed inside the connecting ring, and yarn cotton and an adsorption layer are respectively provided on the right side of the connecting ring. Compared with the existing ordinary dust removal device, the electronic component dust removal device greatly improves the practical performance of the entire device while increasing the structure, and the electronic components are cleaned more comprehensively, and the cleaned dust can be collected independently. At the same time, the improved device can adjust the spacing between the brushes according to the arrangement density of the electronic components, thereby indirectly improving the working efficiency of the device and effectively meeting people's usage needs."

[0005] However, in actual use, although the dust on the electronic components can be absorbed by the brush and sucked away by the fan, some dust will still adhere to the brush and cannot be sucked away by the fan. As a result, when the dust removal continues, dust will still be attached to the brush, affecting the subsequent dust removal effect. Utility Model Content

The insertion rod 403 is located on the side close to the socket 401.

[0054] It should be noted that the length of the brush 1 needs to be smaller than the length of the front end of the handle 2. Place the brush 1 between the socket 401 and the slot 402, then insert the installation roller 406 through the socket 401 and the brush 1 and insert the installation roller 406 into the slot 402. Finally, fix the installation roller 406 through the insertion rod 403. The bottom of the brush 1 must be lower than the bottom of the handle 2 so that the brush 1 can fit the electronic components and roll the brush 1 to absorb dust.

[0055] Example 2:

[0056] On the basis of Example 1, a ventilation assembly is arranged to absorb dust on the brush 1. The ventilation assembly includes a filter 501 arranged on the handle 2 away from the brush 1 for ventilation and dust absorption.

[0057] As a preferred embodiment, the ventilation assembly also includes: a baffle 502, arranged on the side of the handle 2 away from the scraper 301, for limiting the filter 501; a groove 503, arranged above and below the filter 501 in the handle 2, for placing the filter 501; a pressure plate 504, sliding in the handle 2 and located above the filter 501, for pressing the filter 501; a bolt 505, threadedly connected to the handle 2 and the pressure plate 504 is rotatably connected to the bottom of the bolt 505, for driving the pressure plate 504 to move; a vent 506, arranged on the handle 2, for ventilation when the fan 7 is started.

[0059] It should be noted that the dust on the brush 1 is sucked into the handle 2 by the fan 7 and the air is discharged from the filter 501. At this time, the filter 501 absorbs the dust and the pressure plate 504 is driven to loosen and fix the filter 501 by rotating the bolt 505, making it convenient to remove the filter 501 for cleaning and avoid affecting the subsequent ventilation and adsorption effect.

[0060] Example 3:

[0061] On the basis of Example 1 and Example 2, a scraping assembly is arranged to scrape off dust adsorbed on the brush 1 . The scraping assembly includes a scraper 301 arranged in the handle 2 and attached to the brush 1 for scraping off dust on the brush 1 .

[0062] As a preferred embodiment, the scraping assembly also includes: a limiting rod 302, which is fixed in the handle 2 for installing the scraper 301 and the scraper 301 slides on the limiting rod 302; a reset spring 303, which is sleeved on the limiting rod 302 and is used to drive the scraper 301 to reset and always fit the brush 1.

One end of the return spring 303 is fixed inside the handle 2 , and the other end of the return spring 303 is fixed to the scraper 301 .

[0064] It should be noted that the return spring 303 pushes the scraper 301 to always fit the brush 1, so that the dust on the scrapers 301 of different sizes can be scraped off. The front end of the limiting rod 302 does not exceed the front end of the handle 2, so as to avoid the limiting rod 302 fitting into the brush 1 and affecting the scraping effect. Hold the handle 2 and pull the brush 1 to rotate for cleaning. The brush 1 needs to rotate clockwise to achieve the scraping effect.

[0065] The operation steps are as follows: the user first places the brush 1 between the socket 401 and the slot 402, and then inserts the installation roller 406 through the socket 401 and the brush 1 and into the slot 402. At this time, it is necessary to pull the handle 404 to drive the insertion rod 403 to not fit the installation roller 406. After the installation roller 406 is inserted, the slot 402 on the installation roller 406 corresponds to the position of the insertion rod 403. Then, the handle 404 is released and the insertion rod 403 is pushed into the installation roller 406 under the action of the limit spring 405 to fix the installation roller 406. At this time, The brush 1 can rotate on the mounting roller 406, then hold the handle 2 and start the fan 7 to make the brush 1 fit the electronic component, pull the brush 1 to move on the electronic component and rotate it clockwise, at this time the scraper 301 will scrape the dust of the electronic component attached to the brush 1 into the handle 2, and blow it to the filter 501 through the fan 7 for adsorption. After the cleaning is completed, turn the bolt 505 to drive the pressure plate 504 to move completely into the groove 503, then take out the filter 501 to process the dust on the filter 501, and then install it after the processing is completed.

[0066] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
