[0036] The air outlet interface 121 is provided with an internal thread and is bolted to the first threaded column 125, and a platform 1211 is provided at the lower end of the air outlet interface 121. After being fastened to the first threaded column 125, a channel is formed between the platform 1211 and the back of the fan 123. The length of the channel is slightly smaller than the thickness of the box body 220 plate, so that the contact area can be increased to stabilize the connection during the fastening process.

[0037] The power supply interface 122 is provided with a converter 126 and a mounting hole 1221. Two mounting holes 1221 may be provided. The two mounting holes 1221 are far from each other and symmetrically arranged. The converter 126 is clamped between the mounting holes 1221. Of course, three or more mounting holes 1221 may also be provided. The plurality of mounting holes 1221 may be evenly distributed in the power supply interface 122. The converter 126 is clamped in the space surrounded by the plurality of mounting holes 1221.

[0038] The power supply interface 122 can be connected to an external power source. After being connected to the power supply interface 122, power is supplied to the fan 123. The converter 126 is used for filtering and ballasting the power to play a role in stabilizing the power supply.

[0039] Among them, the exhaust fan assembly 120 includes a fan 123, a first threaded column 125 and a screw column 124. The first threaded column 125 and the screw column 124 are arranged on the back side of the fan 123. The first threaded column 125 is used to connect and fix with the air outlet interface 121, and the screw column 124 is fixed in the mounting hole.

[0040] like Figure 10-12 As shown, in order to increase the stability of the box body 220 during operation, another embodiment provided by the present application is provided with a fixed mounting block 1231 on the back side of the fan 123, a cavity is provided in the mounting block 1231, and fixing studs 1235 are provided around the cavity, a first fixing sleeve 1232 is provided at the upper end, a downward through hole is opened in the middle of the first fixing sleeve 1232, a thread is provided in the through hole, a connecting column 1234 is provided on the outer side of the through hole, a thread is provided at the lower part of the air outlet nozzle 1233, and the air outlet nozzle 1233 is threadedly connected with the first fixing sleeve 1232 for fixing, the first fixing sleeve 1232 is inserted into the fixed mounting block 1231, the connecting column 1234 is fastened with the fixing stud 1235, and then fixed with screws to increase stability.

[0041] In another embodiment of the air inlet assembly 1110, a second fixing sleeve 1111 and a first base 1112 are provided, the first base 1112 is embedded in the first through hole 1201 from the inside of the box body 220, and the second fixing sleeve 1111 is inserted into the first through hole 1201 from the outside of the box body 220. After the second fixing sleeve 1111 and the first base 1112 are inserted and fixed, they are threadedly fixed by a second stud provided on the outside, and then the air inlet interface 111 is threadedly fixed in the second fixing sleeve 1111. It can be understood that a threaded through hole is provided in the second fixing sleeve 1111, and a thread is provided at the lower end of the air inlet interface 111. The fixed distance between the second fixing sleeve 1111 and the first base 1112 is the thickness of the box body 220. This can increase the stability of the air inlet.

[0042] In actual use, ice cubes or coolants are placed inside the box 220. When cold air is needed, air enters from the air inlet, is cooled by ice cubes or coolants, and the internal space is cooled down and then discharged from the air outlet. According to different needs, the power of the exhaust fan is adjustable. When high-power exhaust is used, the outlet or air inlet device is prone to shaking. In order to increase stability, a stabilizing member is added, thereby making the entire cold air box more stable when working. It is understandable that the fan 123 can be a blower, exhaust fan or exhaust fan to extract the cold air in the box 220, and is used in an environment where it is needed. It has a simple structure, good cooling effect, and saves costs, which is much lower than the cost of air conditioners or refrigerators.

[0043] The box cover 110 includes a cover plate 1102 and a card base 1101 fixed on the inner side of the cover plate 1102. The card base 1101 has the same size as the opening of the box body 220. When the box cover 110 is closed on the box body 220, the edge of the cover plate 1102 is flush with the edge of the box body 220.
