[0024] The rainproof component 300 includes a placement box 310 installed on the rainproof top cover 200. Two placement boxes 310 are arranged in the placement box 310. The two placement boxes 310 are symmetrically arranged on the rainproof top cover 200. A rotating rod 320 is arranged in the placement box 310. A rainproof cover 321 is sleeved on the rotating rod 320 in one placement box 310, and a pull rope 322 for pulling the rainproof cover 321 is sleeved on the rotating rod 320 in the other placement box 310. One end of the pull rope 322 is fixedly sleeved on the rotating rod 320, and the other end of the pull rope 322 is fixedly connected to the front end of the rainproof cover 321.

[0025] The rainproof assembly 300 further includes a motor 330 installed in the exhaust cabinet body 100, a driving gear 331 is installed at the output end of the motor 330, a driving rod 340 is arranged on the side of the driving gear 331, bevel gears 341 are installed at both ends of the driving rod 340, the bevel gear 341 at the bottom of the driving rod 340 is meshed with the driving gear 331, a driving gear 323 is fixedly installed at the end of the rotating rod 320, and the driving gear 323 is meshed with the bevel gear 341 at the top of the driving rod 340. A through slot 240 is provided in the rainproof top cover 200, the through slot 240 is connected with the cavity 220 and the exhaust cabinet body 100, the driving rod 340 is inserted in the through slot 240, and a partition 130 is installed in the exhaust cabinet body 100, and the partition 130 is located on the side of the driving rod 340.

[0026] A rain deflector 250 is installed on the rainproof top cover 200. The rain deflector 250 is set as an arc-shaped plate, which helps to guide rainwater to the side of the exhaust cabinet to prevent rainwater from directly entering the exhaust hole, thereby affecting the normal operation of the exhaust cabinet. A second exhaust hole 261 begins to be provided in the exhaust shell 260. The second exhaust hole 261 is connected to the cavity 220, and a plurality of air deflectors 262 are installed in the exhaust hole. A filter net 263 is installed in the first exhaust hole 210 and the second exhaust hole 261, and a plurality of filter holes 264 are provided in the filter net 263. It is used to filter dust and impurities in the exhausted air to protect the environment and the cleanliness of the exhaust system. The air deflector 262 helps to guide the air flow, increase the exhaust efficiency, and reduce noise and wind resistance.

[0027] In normal sunny days, the exhaust fan 230 exhausts hot air and pollutants through the first exhaust hole 210. The rain cover 321 is in a closed state and placed in the placement box 310, which does not affect the exhaust function.

[0028] When it rains, the motor 330 is started manually. The start of the motor 330 causes the rainproof assembly 300 to start working. The motor 330 drives the driving gear 331 to rotate, and the driving gear 331 meshes with the bevel gear 341 at the bottom of the driving rod 340, thereby driving the driving rod 340 to rotate. As the driving rod 340 rotates, the bevel gear 341 at the top of the driving rod 340 meshes with the driving gear 323, driving the rotating rod 320 to rotate. The rotation of the rotating rod 320 pulls the pull rope 322, so that the rainproof cover 321 is unfolded from the placement box 310 and covers the first exhaust hole 210.

[0029] At this time, since the first exhaust hole 210 is covered by the rain cover 321, the hot air cannot be discharged from the first exhaust hole 210, but is discharged through the second exhaust hole 261. In this way, the ventilation and exhaust function inside the exhaust cabinet can still operate normally, while preventing rainwater from entering the exhaust cabinet. Not only can it meet the exhaust needs in rainy weather, but it can also automatically switch the working mode, reduce manual intervention, and improve the reliability and efficiency of the equipment.

[0030] In the present embodiment: through the design of the rainproof top cover 200 and the rainproof assembly 300, the fume hood can automatically unfold the rainproof cover 321 when it rains, covering the exhaust holes, effectively preventing rainwater from entering the exhaust system, and protecting the equipment from the influence of humid and rainy environment. At the same time, the fume hood can also intelligently switch the working mode between sunny and rainy days to ensure normal operation under various weather conditions, reduce the need for manual intervention, and improve the reliability and utilization efficiency of the equipment.

[0031] Embodiment 2: This embodiment is intended to solve the problem that a large amount of heat is generated during the use of the exhaust cabinet. The heat dissipation effect of the heat sink 111 may not be sufficient to meet the heat dissipation requirements inside the exhaust cabinet, resulting in equipment overheating. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 4 .

[0032] A heat sink 111 is installed on the cabinet door 110, and a plurality of heat dissipation holes 112 are provided in the heat sink 111. A groove 113 is provided on the heat sink 111, and an observation window 114 is installed in the groove 113. The observation window 114 is set as a glass window. The operator can clearly see the situation inside the exhaust cabinet, including the working status, through the observation window 114, so as to adjust the operation or monitor the equipment status in time.

[0033] The cabinet door 110 is provided with a handle 115 for convenient opening and closing of the cabinet door 110 , and the handle 115 is provided with an insulating sleeve 116 , which not only facilitates the operator to open and close the cabinet door 110 , but also ensures that there is no risk of electric shock during operation, thereby improving the safety of use.

[0034] In this embodiment, a heat sink 111 is installed on the cabinet door 110 of the exhaust cabinet, and a plurality of heat dissipation holes 112 are opened inside the cabinet, so that when a large amount of heat is generated inside the exhaust cabinet, the heat sink 111 conducts the heat to the outside by contacting the air, and discharges the hot air out of the exhaust cabinet through the heat dissipation holes 112, so as to achieve the purpose of heat dissipation.
