[0035] Referring to Figure 2 And Figure 4 Cooling assembly 9 includes fan 91, and fan 91 bottom is fixedly connected in the top of installation box 2, and fan 91 is inhaled external air and is sent to cooling box 96 by air.The input end of fan 91 is fixedly connected with ventilation cover 92, and ventilation cover 92 is threadedly connected with connecting cover 94 away from fan 91 end, when fan 91 works, external air enters through ventilation cover 92, and filter screen 95 can filter dust, impurities and the like in air, to prevent these pollutants from entering cooling air flow, to avoid pollution tea in turn.

[0036] Fan 91 output end is fixedly connected with cooling box 96, to ensure that the air blown by fan 91 can smoothly enter cooling box 96 and be cooled.Processing.Cooling box 96 is fixedly connected with adapter pipe 97 away from fan 91 side, and adapter pipe 97 is fixedly connected in the top of installation box 2 away from cooling box 96 end, so that the air after cooling can enter installation box 2 through adapter pipe 97 and cool tea.Ventilation cover 92 one end is provided with screw groove 93, and connecting cover 94 is connected in the outside of screw groove 93 by screwing, and filter screen 95 is installed outside connecting cover 94.

[0037] Referring to Figure 1 And Figure 2The installation box 2 is internally fixedly connected with a separation net plate 6 for separating and guiding air flow. The one-way air outlet pipe 53 and the one-way air inlet pipe 54 are fixedly connected on the two sides of the separation net plate 6, and the presence of the separation net plate 6 ensures that the air flow will not be disturbed during the process that the hot air from the installation box 2 enters the circulating box 51 through the one-way air outlet pipe 53.
