[0026] A cleaning mechanism is provided above the extraction component 2. The cleaning mechanism includes a cleaning box 3 slidably fitted on the cabinet body 1. A cleaning cylinder 18 is slidably arranged inside the cleaning box 3. Cleaning holes are formed in the cleaning cylinder 18, and the cleaning cylinder 18 is a hollow structure. A top plate 21 is slidably arranged at one inner end of the cleaning box 3. A top shaft 22 is arranged on the top plate 21. The top shaft 22 cooperates with the cleaning holes on the cleaning cylinder 18 for dredging; the cleaning mechanism further includes two lead screws 16 rotatably installed on both sides inside the cleaning box 3, and lead screw motors 15 fixedly arranged on both sides outside the cleaning box 3. The lead screw motors 15 are used to drive the lead screws 16; a first sliding seat 17 and a second sliding seat 26 are respectively fitted with the two lead screws 16 in a screw pair. The first sliding seat 17 and the second sliding seat 26 are respectively slidably arranged on both sides inside the cleaning box 3; the cleaning cylinder 18 is rotatably installed between the first sliding seat 17 and the second sliding seat 26; a cleaning motor 19 is fixedly arranged on the second sliding seat 26.

The connecting cylinder 24 is rotatably connected and communicated with the end of the cleaning cylinder 18 facing the first sliding seat 17; a collection box 23 is arranged on the cleaning box 3. The collection box 23 is communicated with the connecting cylinder 24 through a collection transmission pipe 25; a top-out electric cylinder 20 is arranged on the cleaning box 3. The top-out electric cylinder 20 is used to control the movement of the top plate 21 and the top shaft 22.

[0027] The working principle of implementing the present invention: The extraction component 2 is placed inside the cabinet body 1 and fixed. Specifically, the extraction component 2 is supported by the support bottom plate 4. The fastening seat 9 is fastened to the fastening portion 12, and the fastening spring 13 is compressed. Moreover, the ejection plate 7 contacts the outer side of the extraction component 2 and supports the extraction component 2. At this time, the ejection spring 8 is compressed and stores elastic potential energy.

[0028] The coolant is circulated and transported through two circulating cooling boxes 5 to perform heat dissipation and cooling. Specifically, the coolant is circulated and transported through the cooling transmission pipe 6, and the cooling transmission pipe 6 surrounds the outside and bottom of the extraction component 2, which is conducive to taking away more heat.

[0029] The inside of the pull-out component 2 is dust-removed by means of a cleaning mechanism. Specifically, the screw motor 15 operates, the screw 16 rotates, the slide 17 and the slide 2 26 slide, so as to drive the cleaning cylinder 18 to slide above the pull-out component 2. The cleaning cylinder 18 is driven by the cleaning motor 19 to rotate, and the collecting box 23 operates to adsorb the dust inside the pull-out component 2. The dust enters the inside of the cleaning cylinder 18 through the cleaning hole on the cleaning cylinder 18, and is transmitted to the collecting box 23 through the connecting cylinder 24 and the collecting and transmitting pipe 25 for collection. The cleaning box 3 can be subsequently pulled out from the cabinet 1 for maintenance.

[0030] Furthermore, the cleaning cylinder 18 can be periodically cleared to avoid clogging of the cleaning hole, which would affect the cleaning operation. Specifically, the cleaning cylinder 18 is controlled to move below the top plate 21, and the top plate 21 and the top shaft 22 are controlled to move by the ejection electric cylinder 20. The top shaft 22 cooperates with the cleaning hole on the cleaning cylinder 18 to push the blockage out of the cleaning hole.

[0031] In the event of an emergency, that is, a fire occurs in the pull-out assembly 2 located inside the cabinet 1, and a fire is detected, the control system issues a command to adsorb the adsorption portion 14 through the electromagnetic adsorption shaft 11, so that the adsorption portion 14 and the release slide bar 10 move, and then the snap-fit portion 12 is offset from the snap-fit seat 9, and under the elastic force of the ejection spring 8, the ejection plate 7 quickly pushes the pull-out assembly 2, and the pull-out assembly 2 that is about to catch fire is pushed out of the cabinet 1 to avoid causing greater damage.
