[0029] Please refer to the attached Figure 1 - Attachment Figure 2 The utility model provides an embodiment: a roof fan with a waterproof structure, including a U-shaped frame 1, the top of the U-shaped frame 1 is fixedly connected to a top plate 5, the middle of the top of the top plate 5 is fixedly connected to a U-shaped baffle 18, the front and rear sides of the U-shaped baffle 18 are rotatably connected to a ventilation rotating plate 17, the front and rear sides of the U-shaped baffle 18 are provided with long grooves 10, the tops of the front and rear sides of the U-shaped baffle 18 are fixedly connected to a fixed block 12, the bottom end of the fixed block 12 is fixedly connected to a telescopic rod 11, and the telescopic rod 11 is fixedly connected to the bottom end of the fixed block 12. The output end of 11 is fixedly connected with a moving bar 9, and the inward side of the moving bar 9 is slidably connected with the inside of the elongated groove 10. The top of the U-shaped baffle 18 is fixedly connected with a rotating shaft 18, and the middle of the outer wall of the rotating shaft 18 is rotatably connected with a telescopic rod 2 16, and the output end of the telescopic rod 2 16 is rotatably connected with a rotating shaft 2 15, and the top of the rotating shaft 2 15 is respectively fixedly connected with the corresponding rotating inclined plate 13, and the left and right sides of the top of the top plate 5 are provided with a leak-proof mechanism 2, and the inner bottom end of the U-shaped frame 1 is fixedly connected with an anti-slip pad 3;

[0030] Specifically, the top plate 5 plays a role of bearing and stabilizing in this structure, and a U-shaped baffle 18 is further fixedly connected to the middle of its top, and the design of the U-shaped baffle 18 is to provide additional support and protection. The interior of the U-shaped baffle 18 is quite delicate, and the front and rear sides are rotatably connected with ventilation rotating plates 17, and these ventilation rotating plates 17 can be rotated according to actual conditions. The structure of these fixed blocks 12 is designed to support the telescopic rod 11 below. The telescopic rod 11 is an adjustable length, considering practicality and adjustability.

[0031] Please refer to the attached Figure 3 The anti-leakage mechanism 2 includes a material storage tank 201, the bottom end of which is fixedly connected to the left and right sides of the top of the top plate 5, and a Z-shaped rotating rod 205 is rotatably connected to the middle of the rear side of the material storage tank 201. The front end of the Z-shaped rotating rod 205 passes through the rear side of the material storage tank 201 and is fixedly connected to a rotating rod 206. The outer wall of the rotating rod 206 is fixedly connected to a rotating blade 207. The outward side of the material storage tank 201 is connected to a discharge plate 204, and a baffle 203 is engaged with the middle of the top of the discharge plate 204. The left and right sides of the top plate 5 are fixedly connected to a hollow tank 6, and the bottom end of the hollow tank 6 is connected to a water outlet 7.

[0032] Specifically, a Z-shaped rotating rod 205 is installed through the middle of the rear side of the storage tank 201. The design of this Z-shaped rotating rod 205 is very clever. Its front end passes through the rear side of the storage tank 201 and is fixedly connected to the rotating rod 206. When the Z-shaped rotating rod 205 rotates, it drives the rotating rod 206 to rotate together. Rotating blades 207 are evenly fixedly connected to the outer wall of the rotating rod 206. These rotating blades 207 rotate with the rotation of the rotating rod 206, playing the role of stirring or pushing the material, so that the material can be smoothly released from the storage tank 201.

[0033] Please refer to the attached Figure 1 - Attachment Figure 2 The front middle part of the storage tank 201 is connected with a feed pipe 202, the middle part of the inner bottom end of the U-shaped baffle 18 is fixedly connected with a ventilator 14, the inner right end of the U-shaped frame 1 is fixedly connected with a controller 4, the controller 4 is electrically connected with the telescopic rod 2 16, the telescopic rod 1 11 and the ventilator 14 respectively, and the top of the rotating inclined plate 13 is fixedly connected with a protective plate 19;

[0034] Specifically, the storage tank 201 is a key component, which is designed to store and process materials. The front middle part of the storage tank 201 is specially designed to be connected to the feed pipe 202. This layout allows the material to enter the tank efficiently so that a ventilator 14 can be fixedly connected to ensure air circulation and temperature control, which is crucial for maintaining the quality of the material in the storage tank 201 and preventing the material from deteriorating. In the design of the U-shaped frame 1, a controller 4 is fixedly connected to the inner right end, and the installation position of the controller 4 is convenient for the operator to monitor and adjust.

[0035] Working principle: when the roof fan needs to be used, first install the U-shaped baffle 18 on the top middle part of the top plate 5, and then install the ventilation rotating plate 17 on the front and rear ends of the U-shaped baffle 18 respectively. At this time, when it rains in the weather, open the telescopic rod 11 fixedly connected to the fixed block 12, so that the moving bar 9 moves downward along the inside of the elongated groove 10, thereby contacting the ventilation rotating plate 17, and swing the ventilation rotating plate 17 so that the ventilation rotating plate 17 is in a vertical state, thereby performing a closing operation to effectively block rainwater. When the rainfall is heavy, the telescopic rod 2 16 fixedly connected to the rotating shaft 18 cooperates with the rotating shaft 2 15 to pull the two rotating inclined plates 13 inward respectively, so that the two rotating inclined plates 13 are The movable inclined plate 13 is triangular in shape, so rainwater flows to the top of the U-shaped baffle 18, thereby improving the waterproof performance to a certain extent. At the same time, it can be distinguished and adjusted according to the amount of rainfall to avoid the situation where the ventilation effect is not ideal, and it has good promotion properties. Subsequently, the waterproof material is placed into the inner side of the storage tank 201 through the feed pipe 202. At this time, the Z-shaped rotating rod 205 is rotated, thereby coordinating the rotation of the rotating rod 206 and the rotating blade 207 to effectively mix the waterproof material. Finally, the baffle 203 is opened and the discharge plate 204 is cooperated to evenly flow to the top outer wall of the top plate 5. Therefore, it is possible to effectively maintain the normal operation of the fan and avoid excessive water accumulation on the roof from seeping into the fan, affecting the use effect of the fan.
