[0030] like Figure 1-4 As shown, the utility model provides a low-temperature cooling circulation pump, which has a circulation pump body 1, wherein a heat sink 2 connected to the inside of the circulation pump body 1 is fixedly installed on the left and right side walls of the circulation pump body 1, and a dustproof net 20 is provided at one end of the heat sink 2 away from the circulation pump body 1, and a plurality of obliquely arranged dustproof blades 21 are fixedly installed at an equal distance at one end of the heat sink 2 close to the dustproof net 20;

[0031] A dust removal plate 22 is slidably connected in the heat dissipation box 2. The dust removal plate 22 is sleeved on the outer wall of the dust-proof blade 21. A plurality of cleaning grooves 23 are evenly spaced on the dust removal plate 22. The cleaning grooves 23 correspond to the dust-proof blades 21 one by one and are slidably connected thereto.

[0032] A guide hole 24 is provided in the middle of the dust removal plate 22, and a screw rod 25 is longitudinally rotatably connected to the heat dissipation box 2, and the screw rod 25 is threadedly connected to the guide hole 24;

[0033] The side of the dust removal plate 22 close to the dustproof net 20 is a complete planar structure, and a plurality of bristles are evenly distributed on the planar structure, and the bristles abut against the dustproof net 20.

[0034] Optionally, in the above technical solution, a receiving cavity 41 is provided on the inner top wall and the inner bottom wall of the heat dissipation box 2 , and an adjustment hole 42 is provided on the outer top wall and the outer bottom wall of the heat dissipation box 2 , and the receiving cavity 41 is connected to the adjustment hole 42 .

[0035] Optionally, in the above technical solution, a clamping block 5 is slidably connected in the accommodating cavity 41 , and the left and right side walls of the dustproof net 20 are respectively abutted against the left and right inner walls of the clamping block 5 .

[0036] Optionally, in the above technical solution, a screw rod 43 is connected to the inner thread of the adjustment hole 42 , one end of the screw rod 43 is fixedly connected to the clamping block 5 , and a knob 44 is fixedly mounted on the other end of the screw rod 43 .

[0037] Optionally, in the above technical solution, a support plate 31 is fixedly installed in the heat dissipation box 2, and an internal drive motor 32 is fixedly installed on one side of the support plate 31 close to the circulating pump body 1, and the output shaft of the internal drive motor 32 extends toward the dustproof net 20 and passes through the support plate 31.

[0038] Optionally, in the above technical solution, the output shaft of the inner driving motor 32 is rotatably connected to the support plate 31 and a rotating column 33 is fixedly installed at the end, and a plurality of fan blades 34 are fixedly installed at equal intervals on the outer peripheral surface of the rotating column 33 .

[0039] The left and right ends of the heat dissipation box 2 are both arranged without end covers, which facilitates the heat dissipation of the circulation pump body 1.

[0040] Among them, an external drive motor 6 is fixedly installed on the rear wall of the heat dissipation box 2 at a position corresponding to the dust removal plate 22, and the output shaft of the external drive motor 6 extends forward and passes through the rear wall of the heat dissipation box 2. The output shaft of the external drive motor 6 is rotatably connected to the rear wall of the heat dissipation box 2 and is fixedly connected to the rear end of the screw rod 25, so as to drive the screw rod 25 to rotate.

[0041] Working principle:

[0042] In the initial state, the dust removal plate 22 is close to the rear wall or the front wall of the heat sink 2. When dust needs to be cleaned, the external drive motor 6 is started to drive the screw 25 to rotate in situ, so that the screw 25 drives the dust removal plate 22 to move forward or backward, that is, the cleaning groove 23 moves along the outer wall of the dust-proof blade 21 to scrape off the dust accumulated on the dust-proof blade 21, and at the same time, the bristles follow the movement of the dust removal plate 22 to clean the dust on the dust-proof net 20;

[0043] When there is too much dust on the dustproof net 20, the reverse rotation knob 44 drives the clamping block 5 on the screw 43 to move into the accommodating cavity 41, so that the clamping block 5 does not abut against the dustproof net 20, that is, the clamping block 5 does not limit the dustproof net 20. At this time, the dustproof net 20 is removed for replacement.

[0044] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
