[0030] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem in the prior art that the filter mechanism needs to be cleaned manually and regularly, which wastes manpower and increases the workload of the staff, and when it is not cleaned for a period of time, it is easy to cause dust accumulation, which is easy to affect its use effect, the following scheme is disclosed, including a cabinet 1, and a cabinet door 2 is hinged on the front side of the cabinet 1; and further comprising: a heat dissipation fan 3 is arranged inside the upper surface of the cabinet 1, and a main shaft 4 is fixed in the middle of the heat dissipation fan 3, and the lower end of the main shaft 4 is connected to the cabinet 1 bearing, and the upper end of the main shaft 4 passes through the dustproof net 6 and is connected to the cleaning rod 7, and a brush 8 is fixed on the lower surface of the cleaning rod 7;

[0032] By connecting the heat dissipation fan 3 with the external motor, the external motor can drive the heat dissipation fan 3 to rotate, so that the heat dissipation fan 3 can achieve the effect of heat dissipation, and while the heat dissipation fan 3 rotates, it will also drive the main shaft 4 to rotate together, and through the rotation of the main shaft 4, it can be engaged with the limit block 11 and the card slot 10, thereby driving the cleaning rod 7 to rotate together, and through the rotation of the cleaning rod 7, it can drive the brush 8 to clean the dust attached to the dustproof net 6, thereby achieving the effect of automatic cleaning, so that there is no need for manual cleaning, saving labor and reducing the workload of the staff, avoiding dust and the like from attaching and affecting the air entry, thereby ensuring the heat dissipation effect of the heat dissipation fan 3;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the removal of the cleaning rod 7 for cleaning and replacement. Figure 4-Figure 7 The right side of the main shaft 4 is slidably engaged with a limited block 11, and a pressure spring 12 is fixed to the left side of the limited block 11, and the left end of the pressure spring 12 is fixed to the main shaft 4, and a clamping connection is formed between the limited block 11 and the card slot 10, the card slot 10 is opened inside the cleaning rod 7, and the surface of the cleaning rod 7 is slidably connected with a push rod 9, and the push rod 9 is arranged in an "L" shape. The outer side surface of the main shaft 4 is welded and fixed with a limited block 13, and the upper end surface of the limited block 13 is in contact with the lower surface of the cleaning rod 7;

[0034] After the cleaning is completed, the cleaning rod 7 can be sleeved on the main shaft 4, and the cleaning rod 7 can be sleeved on the main shaft 4 by pressing the cleaning rod 7 downward, so that the lower end of the cleaning rod 7 can contact the limiting block 11, and the inclined structure of the upper surface of the limiting block 11 can be set, so that the limiting block 11 can slide to the left side. When the lower side surface of the cleaning rod 7 moves to contact the limiting block 13, the slot 10 has moved to be parallel to the limiting block 11. At this time, the elastic force of the pressure spring 12 drives the limiting block 11 to engage with the slot 10 again, thereby realizing the installation of the cleaning rod 7;

[0035] Embodiment 3: Different from Embodiment 2, this embodiment facilitates the removal of the dust cover 5 for replacement. Figure 1-Figure 3 The upper surface of the cabinet 1 is provided with a dust cover 5, and the inner wall of the dust cover 5 is fixed with a dust net 6, and the lower end surface of the dust cover 5 is bonded with a sealing ring 14, and the sealing ring 14 fits with the cabinet 1, and the outer side of the dust cover 5 is fixed with an insert block 15, and the insert block 15 is arranged in a "7" shape, and the lower end of the insert block 15 fits with the cabinet 1, and the inside of the insert block 15 is clamped with a clamp rod 16, and the outer end of the clamp rod 16 is fixed to the trapezoidal block 17, and the trapezoidal block 17 is fixed to the cabinet 1 is formed in a sliding connection, and a first return spring 18 is sleeved on the outer side of the clamping rod 16, and one end of the first return spring 18 is fixed to the cabinet 1, and the other end of the first return spring 18 is fixed to the trapezoidal block 17, and a pressure rod 19 is slidably connected to the upper surface of the cabinet 1, and a second return spring 20 is sleeved on the outer side of the pressure rod 19, and the upper end of the second return spring 20 is fixed to the pressure rod 19, and the lower end of the second return spring 20 is fixed to the upper surface of the cabinet 1;

[0036] Moreover, a sealing ring 14 is bonded to the lower end of the dust cover 5, and the sealing ring 14 fits with the upper surface of the cabinet 1 to achieve a sealing effect, and by pulling the pressure rod 19 upward, the lower end of the pressure rod 19 does not contact the trapezoidal block 17. At this time, the elastic force of the first reset spring 18 drives the trapezoidal block 17 to reset, so that the trapezoidal block 17 drives the clamping rod 16 to reset together, so that the inner end of the clamping rod 16 is separated from the plug block 15, thereby releasing the limit of the plug block 15, and the dust cover 5 can be removed at this time. The dust cover 5 and the dust net 6 can be replaced by manually pressing the limit block 11, and the limit block 11 will not block the dust cover 5 and the dust net 6. Then, the new dust cover 5 and the dust net 6 need to be installed, and then the pressure rod 19 is released. At this time, the second return spring 20 is used to drive the pressure rod 19 downward. At this time, the lower end of the pressure rod 19 will squeeze the trapezoidal block 17, so that the trapezoidal block 17 drives the card rod 16 to slide inward, so that the card rod 16 is engaged with the plug block 15 again, thereby realizing the installation and fixation of the dust cover 5.
