[0029] It can be understood that the description of the present application is only used to explain the present application, and cannot be understood as a limitation of the present application. Figures 1 to 4The utility model discloses an exhaust fan with lighting function, including the mechanism of drawing wind 100, deflector 200 and light 300, the mechanism of drawing wind 100 includes the support cylinder 110, motor 120 and fan blade 130, motor 120 fixedly connected in the support cylinder 110, fan blade 130 is connected in the output of motor 120, and motor 120 is used for driving fan blade 130 rotation, deflector 200 fixedly connected in the lower end of support cylinder 110, and deflector 200 and support cylinder 110 are interval arrangement, and the side of deflector 200 close to support cylinder 110 protrudes and is provided with the convex part 210, and the convex part 210 is set with the mounting hole 211, light 300 is set in the mounting hole 211, and light 300 and support cylinder 110 are detachably connected.

[0030] Motor 120 is fixedly connected in the support cylinder 110, and fan blade 130 is fixedly connected in the output of motor 120, and deflector 200 is fixedly connected in the lower end of support cylinder 110, and deflector 200 and support cylinder 110 are interval arrangement, and through motor 120 drive fan blade 130 rotation, make fan blade 130 can drive airflow from the clearance between deflector 200 and support cylinder 110 and flow into the support cylinder 110, to extract water vapor. The convex part 210 of deflector 200 protrudes to the direction close to support cylinder 110, and light 300 is set in the mounting hole 211 of convex part 210, so that when water vapor condenses into water droplets on the support cylinder 110, the water droplets can be received by the deflector 200, and the convex part 210 on the deflector 200 can block the water droplets from flowing on the deflector 200, thereby reducing the possibility of water entering the light 300, and the light 300 and the support cylinder 110 are detachably connected, which facilitates the disassembly and assembly of the light 300, facilitates the maintenance of the light 300, and improves the reliability.

[0031] It should be noted that the motor 120 drives the fan blade 130 to rotate, so that the airflow can flow into the support cylinder 110 from between the support cylinder 110 and the deflector 200, so that the water vapor is easily condensed into water droplets on the support cylinder 110, and the water droplets are easily dropped on the deflector 200. By protruding the convex part 210 on the side of the deflector 200 close to the support cylinder 110, the flow of water droplets on the deflector 200 is blocked, thereby reducing the possibility of water droplets flowing into the mounting hole 211 and reducing the possibility of water entering the light 300, thereby improving the reliability.

[0032] In addition, the deflector 200 is connected to the lower end of the support cylinder 110 to guide the airflow to flow into the support cylinder 110 radially from the support cylinder 110, reduce the contact between the airflow and the light 300, and reduce the possibility of water vapor condensing on the light 300, thereby reducing the risk of water entering the light 300 and improving the reliability.

[0033] It can be understood that, with reference to Figure 3 andFigure 4 The side of the flow guide plate 200 away from the support cylinder 110 is provided with a recess 220, the recess 220 is arranged around the mounting hole 211, and the side wall of the recess 220 is arranged in an inclined manner.

[0034] It should be noted that the convex part 210 and the recess 220 are integrally formed, so that the thickness of the flow guide plate 200 is uniform, and the structural strength of the flow guide plate 200 is improved. The flow guide plate 200 can be formed by stamping, injection molding or the like, which reduces the manufacturing difficulty and cost of the flow guide plate 200.

[0035] It can be understood that, with reference to Figure 3 The cross-sectional shape of the flow guide plate 200 is arranged in an arc shape, and the flow guide plate 200 protrudes away from the support cylinder 110. By arranging the cross-sectional shape of the flow guide plate 200 in an arc shape, and the flow guide plate 200 protrudes away from the support cylinder 110, so that the flow guide plate 200 can better receive the water droplets dropped by the support cylinder 110, so that the water droplets can be stabilized on the flow guide plate 200, reducing the influence of airflow on the water droplets, reducing the possibility of water droplets being blown away by the airflow, thereby reducing the risk of water entering the lighting lamp 300.

[0036] In addition, the arc-shaped flow guide plate 200 can better guide the flow of airflow, so that the airflow is smoother when passing between the flow guide plate 200 and the support cylinder 110, reducing the resistance and vortex phenomenon of the airflow, thereby improving the air extraction efficiency of the exhaust fan.

[0037] Specifically, with reference to Figure 2 and Figure 3 The flow guide plate 200 is provided with a water blocking edge 230, which is arranged along the circumference of the flow guide plate 200. By arranging the water blocking edge 230 on the upper end of the flow guide plate 200, the flow of water droplets on the flow guide plate 200 is blocked, avoiding the water droplets flowing to the lighting lamp 300 over the edge of the flow guide plate 200, thereby reducing the possibility of water droplets accumulating around the lighting lamp 300, reducing the possibility of water entering the lighting lamp 300, and improving reliability.

[0038] It should be noted that the deflector 200 is protrudingly arranged away from the support cylinder 110, so that the water droplets are easy to flow along the lower end surface of the deflector 200 towards the lighting lamp 300, and the water droplets on the upper end of the deflector 200 are blocked by the water-blocking edge 230, avoiding the water droplets from flowing over the edge of the deflector 200, so as to reduce the possibility of water droplets flowing to the lighting lamp 300, and improve the reliability.

The opening or closing of the support cylinder 110 is facilitated by the baffles 141, the unidirectional flow of air is realized, the backflow of air is avoided, and the stability of use is improved.

[0041] When the motor 120 drives the fan blade 130 to rotate, the air flow moves along the axial direction of the support cylinder 110 towards the direction close to the baffle 141, so that the air flow can push away the baffle 141 and smoothly exhaust the air flow;

[0042] When the external air flow blows into the support cylinder 110, the air flow can push the baffle 141 to rotate and abut and press on the connecting ring 140, so as to close the support cylinder 110 and avoid the backflow of air.

[0043] It should be noted that the connecting ring 140 and the support cylinder 110 can be connected by buckling or fasteners, which are not limited here.
