[0032] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] Refer to Figures 1-6, a dust-proof cooling fan 100, comprising: a fan housing 101, a protective frame 102, a motor 103, a connecting disc, a fan blade, a mounting frame 104, a dust-proof net 105, and a fixing component for fixing the dust-proof net 105 to the fan housing 101. The protective frame 102 is fixedly connected to the fan housing 101. The motor 103 is fixedly connected to the protective frame 102. The connecting disc is fixedly connected to the drive shaft of the motor 103, and the fan blade is fixedly connected to the connecting disc. The mounting frame 104 is inserted into the fan housing 101. The dust-proof net 105 is located within the mounting frame 104 and is fixedly connected to the mounting frame 104. The mounting frame 104 includes a mounting block 104a, and the fan housing 101 includes a mounting groove 101a for inserting the mounting block 104a.

[0034] The fixing component is used to fix the dust-proof net 105 to the fan housing 101, and includes: a limiting post 106, a connecting block 107, a first spring 108, and a driving member for driving the connecting block 107 to move. The limiting post 106 is radially slidably connected to the fan housing 101. Specifically, the fan housing 101 includes a guiding hole 101b, and a part of the limiting post 106 is located within the guiding hole 101b and moves along the axial direction of the guiding hole 101b. The connecting block 107 is fixedly connected to the limiting post 106. The first spring 108 is sleeved on the limiting post 106, and both ends are fixedly connected to the fan housing 101 and the connecting block 107 respectively. Among them, the mounting frame 104 includes a limiting hole 104b for inserting the limiting post 106.

[0035] The driving member is used to drive the movement of the connecting block 107, and includes: a pushing ring 109, a driving block 110, and a transmission block 112. The pushing ring 109 is horizontally slidably connected to the fan housing 101. Specifically, the fan housing 101 is provided with a first sliding groove extending along the axial direction of the fan housing 101, and the pushing ring 109 moves along the first sliding groove. The driving block 110 is fixedly connected to the pushing ring 109. The transmission block 112 is fixedly connected to the connecting block 107. The driving block 110 includes a driving inclined surface 110a, and the transmission block 112 includes a transmission inclined surface 112a, and the driving inclined surface 110a and the transmission inclined surface 112a are in contact. There are multiple limiting posts 106, connecting blocks 107, driving blocks 110, and transmission blocks 112, which are evenly distributed along the circumferential direction of the fan housing 101. By pushing the pushing ring 109, the movement of the pushing ring 109 drives the movement of the driving block 110. The driving inclined surface 110a of the driving block 110 drives the transmission block 112 to move through the transmission inclined surface 112a. The movement of the transmission block 112 drives the movement of the connecting block 107, and the movement of the connecting block 107 drives the movement of the limiting post 106, so that the limiting post 106 is disengaged from the limiting hole 104b, and the mounting frame 104 can be taken out. Therefore, the disassembly of the dust-proof net 105 is more convenient.

[0036] Workflow: When in use, the fan housing 101 is fixed to the device by screws. The motor 103 drives the connection disk to rotate, and the rotation of the connection disk drives the fan blades to rotate, thereby ventilating the interior of the device. In order to prevent dust from entering the device, a dust-proof net 105 is provided at the air outlet position of the fan housing 101. Prolonged use will cause dust to adhere to the dust-proof net 105, resulting in a reduced ventilation effect. Therefore, it is necessary to replace the new dust-proof net 105. Just push the push ring 109, the movement of the push ring 109 drives the drive block 110 to move, and the drive inclined surface 110a of the drive block 110 drives the transmission block 112 to move through the transmission inclined surface 112a. The movement of the transmission block 112 drives the connection block 107 to move, and the movement of the connection block 107 drives the limit post 106 to move, so that the limit post 106 disengages from the limit hole 104b, and then the mounting frame 104 can be taken out. Therefore, the disassembly of the dust-proof net 105 is more convenient, and the new dust-proof net 105 can be replaced.

[0037] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
