Description

Technical Field

[0001] The utility model relates to the technical field of chassis cleaning, and specifically to a computer chassis cleaning device. Background Art

[0002] The cleaning problem inside a computer chassis has always been an important part of computer maintenance. To ensure the normal operation of the computer system and the good heat dissipation of its internal components, it is essential to regularly clean the inside of the chassis. Currently, the computer chassis cleaning devices widely circulated in the market mainly rely on hair dryers to perform dust cleaning operations. This method blows out the dust inside the chassis through a strong airflow to achieve the purpose of cleaning.

[0003] However, in actual operation, this traditional cleaning method has many inconveniences and deficiencies. First of all, due to the fact that the inside of the computer chassis has not been cleaned in time for a long time, the dust often accumulates severely. When using a hair dryer for cleaning, the strong airflow will cause the dust to fly everywhere, making the cleaning site even more messy and dirty, and increasing the difficulty of subsequent cleaning work. In addition, the dust inside the chassis often adheres tightly to the surfaces of various components and parts, and simply relying on the airflow of the hair dryer cannot completely remove this dust.

[0004] The disclosure of the above background art content is only used to assist in understanding the concept and technical solution of the present utility model, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background art should not be used to evaluate the novelty and inventiveness of this application. Summary of the Utility Model

[0005] This application provides a computer chassis cleaning device, which can reduce the phenomenon of dust scattering and improve the cleaning efficiency.

[0006] To achieve the above object, this application adopts the following technical solutions:

[0007] A computer case cleaning device includes a housing, a battery, a vacuum pump, control buttons, a dust collection box, a filter screen, and a brush. The housing includes a first housing part and a second housing part. The second housing part is tubular, and a dust suction port is provided on one end surface of the second housing part in a first direction. The first direction is parallel to the central axis of the second housing part. The battery is arranged inside the first housing part. The battery and the dust suction port are arranged at intervals in the first direction. The vacuum pump is electrically connected to the battery, and the vacuum pump is arranged inside the first housing part and is located between the battery and the dust suction port. One end of the second housing part is communicated with the input end of the vacuum pump. An air discharge port is provided on the surface of the first housing part facing away from the dust suction port, and the output end of the vacuum pump is communicated with the air discharge port. The control buttons are arranged on the outer surface of the first housing part, and the control buttons are electrically connected to the battery. A dust collection port is provided on the second housing part, and the dust collection port is located between the vacuum pump and the dust suction port. The dust collection box is detachably connected to the dust collection port. The filter screen is arranged inside the second housing part and is located between the vacuum pump and the dust suction port. The brush is arranged on the surface of the second housing part where the dust suction port is provided.

[0008] In the embodiment of the present application, the user presses the control button to connect the circuit between the battery and the vacuum pump, so that the vacuum pump starts. The vacuum pump generates negative pressure by being powered by the battery. Since air always flows from the high-pressure area to the low-pressure area, external air will carry dust and enter the second housing part through the dust suction port, and flow along the internal channel of the housing to the input end of the vacuum pump, thus avoiding the dust flying around and keeping the cleaning site clean, effectively solving the problem that dust scatters everywhere when the traditional hair dryer is used to clean dust.

[0009] Before the inhaled dust enters the vacuum pump, it enters the dust collection box through the dust collection port for collection. The dust collection box is designed to be detachable, which is convenient for the user to remove and clean the collected dust after cleaning. The air that brings the dust into the housing interior finally discharges out of the device through the air discharge port via the discharge end of the vacuum pump. The air discharge port is provided on one side of the first housing part facing away from the dust suction port, which can ensure that the air can be discharged smoothly and can prevent the discharged air from acting on the interior of the computer case. In addition, the user can also use the mechanical friction of the brush to loosen the dust attached to the surface of the components, and cooperate with the suction of the vacuum pump to suck the loosened dust into the dust suction port, improving the cleaning effect.

[0010] In some possible implementation manners, the number of the filter screens is multiple, and the multiple filter screens are arranged at intervals in the first direction. In this way, different-sized dust particles are filtered hierarchically, improving the filtering effect.

[0011] In some possible embodiments, a protruding portion is provided at a position corresponding to the dust collection port on the second housing portion. A first sliding groove is formed in the protruding portion, and the first sliding groove communicates with the dust collection port. The first sliding groove penetrates through the surface of the protruding portion facing away from the brush. The dust collection box is slidably disposed in the first sliding groove in a first direction. In this way, the convenience of disassembling and installing the dust collection box is improved, facilitating user operation.

[0012] In some possible embodiments, a rubber pad is provided on the outer surface of the dust collection box. On the one hand, the friction between the dust collection box and the wall surface of the first sliding groove can be increased, making it more stable to fix; on the other hand, better sealing performance can be provided to prevent dust leakage.

[0013] In some possible embodiments, the output end of the vacuum pump is communicated with the air discharge port through a first hose, and the output end of the vacuum pump is communicated with one end of the second housing portion through a second hose. In this way, due to the flexibility and bendability of the first hose and the second hose, the angles and positions of the first hose and the second hose can be easily adjusted, facilitating the connection of the output end and the input end of the vacuum pump to the air discharge port and the second housing portion respectively.

[0014] In some possible embodiments, a plurality of friction bumps are provided on the outer surface of the housing. In this way, the friction during holding can be increased to prevent slipping. Description of the Drawings

The vacuum pump 3 generates negative pressure by being powered by the battery 2. Since air always flows from the high-pressure area to the low-pressure area, external air will carry dust and enter the second housing part 12 through the dust suction port 121 and flow along the internal channel of the second housing part 12 to the input end of the vacuum pump 3, thus avoiding the dust from flying around and keeping the cleaning site clean, effectively solving the problem that dust scatters everywhere when the traditional hair dryer cleans dust.
