Description

Technical Field

[0001] This invention relates to the field of computer equipment protection technology, and specifically to a dust protection device for computer equipment. Background Technology

[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. The computer's main unit is like its brain, containing components such as the motherboard, power supply, and memory. During operation, it generates considerable heat. Current computer main units typically use cooling fans for heat dissipation, with dust filters installed at the fan's inlet and outlet to prevent dust from entering and damaging the components. However, after prolonged use, dust can clog the filters, hindering heat dissipation and affecting computer performance, requiring regular manual cleaning. While some computer cases now automatically clean their dust filters, this process often breaks up dust particles, which are then sucked into the case, resulting in poor dust protection. Therefore, a dust protection device for computer equipment is needed to address these issues. Summary of the Invention

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-8 The present invention provides a technical solution:

[0025] A dustproof protection device for computer equipment includes a protective housing 1, a dust filter 2, and a fan box 3. The dust filter 2 is disposed on the front and rear end faces of the protective housing 1. The fan box 3 is connected to the inner wall of the protective housing 1, and the opening of the fan box 3 faces the dust filter 2. A cooling fan 4 is slidably connected inside the fan box 3. A power conversion component 5 for supplying power to the cooling fan 4 is installed on the fan box 3. The power conversion component 5 includes a terminal block 51 and power contacts 52. The terminal block 51 is installed on the side of the fan box 3. The terminal block 51 is provided with three power contacts 52. The power contacts 52 on both sides are arranged with opposite polarities to the power contacts 52 in the middle position. The power contacts 52 can be connected to the conductive posts provided on the cooling fan 4. The power conversion component 5 can switch the direction of the cooling fan 4 after it slides, so that the cooling fan 4 can meet the heat dissipation and dust removal requirements.

[0026] The air box 3 is also equipped with a cleaning component 6 for cleaning the dust filter 2. The cleaning component 6 includes a cleaning brush 61, a driven crown gear 62, and a driving crown gear 63. The cleaning brush 61 is rotatably connected to the air box 3 via a shaft. The driven crown gear 62 is keyed to the rotating shaft of the cleaning brush 61. The fan blades of the cooling fan 4 are fixedly connected to the driving crown gear 63, which can mesh with the driven crown gear 62. The cleaning component 6 can clean the dust on the dust filter 2.

[0027] The protective housing 1 is equipped with a switching assembly 7 for driving the cooling fan 4 to slide. The switching assembly 7 includes a switching frame 71, a rack 72, and a motor bracket 73. The switching frame 71 is slidably connected to the bottom of the protective housing 1, and its two ends are respectively connected to the cooling fans 4 arranged on both sides of the protective housing 1. The rack 72 is fixedly connected to the switching frame 71. A drive motor 74 is connected to the protective housing 1 through the motor bracket 73. The output end of the drive motor 74 is keyed to a switching gear 75 that meshes with the rack 72. The switching frame 71 has a U-shaped structure, which avoids wasting the internal space of the protective housing 1. The switching assembly 7 can drive the cooling fan 4 to slide in the air box 3, thereby enabling the switching of the direction of the cooling fan 4 and switching the driving state of the cleaning assembly 6.

[0028] The protective housing 1 is equipped with a mounting assembly 8 for shock absorption and protection of the motherboard. The mounting assembly 8 includes a fixing plate 81, a support frame 82, and a guide rod 83. The fixing plate 81 is connected to the side wall of the protective housing 1, and the support frame 82 is connected to the fixing plate 81. The guide rod 83 is connected inside the support frame 82, and a slider 84 is slidably connected to the guide rod 83. A buffer spring 85 for buffering the slider 84 is connected to the guide rod 83. A mounting plate 86 for mounting the motherboard is fixedly connected to the slider 84. The mounting plate 86 is provided with heat dissipation grooves, which can improve the heat dissipation efficiency of the motherboard. The mounting assembly 8 can provide shock absorption for the motherboard, thereby effectively protecting the motherboard when the host is impacted.

[0029] The working process of this invention is as follows:

[0030] When the computer host is started, the cooling fan 4 on the front side of the protective housing 1 draws air into the protective housing 1, and the cooling fan 4 on the rear side of the protective housing 1 exhausts air out of the protective housing 1, thus forming an air circulation to achieve heat dissipation for the electrical components inside the protective housing 1; at the same time, the driving crown gear 63 on the cooling fan 4 on the rear side of the protective housing 1 meshes with its corresponding driven crown gear 62, and the cooling fan 4 drives the cleaning brush 61 to rotate to clean the dust filter 2 on the rear side of the protective housing 1, while the cleaning brush 61 on the front side of the protective housing 1 does not rotate at this time.

[0031] When a large amount of dust accumulates on the dust filter 2 on the front side of the protective housing 1, the drive motor 74 rotates, driving the switching gear 75 to rotate. The switching gear 75 drives the switching frame 71 to slide on the protective housing 1 via the rack 72. This causes the switching frame 71 to move the cooling fans 4 on both the front and rear sides of the protective housing 1 to the front side simultaneously. The conductive posts on the cooling fans 4 and the power conversion component 5 move relative to each other, causing the polarity of the power supply on the cooling fans 4 to change. The cooling fans 4 begin to rotate in opposite directions, that is, the cooling fans 4 on the front side of the protective housing 1 exhaust air to the outside, while the cooling fans 4 on the rear side of the protective housing 1 draw air into the protective housing 1. At this time, the cleaning component 6 on the rear side of the protective housing 1 stops rotating, while the cleaning component 6 on the front side of the protective housing 1 begins to rotate to clean the dust filter 2, ensuring that the dust filter 2 is always cleaned during the exhaust process, preventing smaller particles broken up during cleaning from being sucked into the protective housing 1. The rotation of the drive motor 74 can switch the heat dissipation direction again.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
