Description

Technical fields:

[0001] This utility model relates to the field of exhaust fan lights, and more particularly to a waterproof and dustproof exhaust fan light panel. Background technology:

[0002] Traditional exhaust fans are air conditioning appliances that use an electric motor to drive the fan blades to rotate and create airflow, exchanging indoor and outdoor air. Nowadays, almost every household has an exhaust fan installed in their bathroom, along with a light fixture. Therefore, exhaust fans and panel lights are now often combined, with the panel light installed in the middle of the exhaust fan and ventilation slots around the light. However, existing exhaust fan lights installed in bathrooms use a driver to power LED lights. In bathrooms, due to the high humidity and poor sealing, the driver can easily short-circuit, affecting the operation of the exhaust fan and the light fixture. Utility Model Content:

[0003] Based on this, the present invention aims to overcome the defects of the prior art and provide a waterproof and dustproof exhaust fan light panel. The present invention aims to solve the problem that in the past, when exhaust fan lights were installed in the bathroom, the panel lights used a driver power supply to drive the LED lights. In the bathroom, due to the high humidity and poor sealing, the driver power supply was prone to short circuit, which affected the use of the exhaust fan lights.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The purpose of this utility model is to provide a waterproof and dustproof exhaust fan light panel, including an outer frame and a panel light. The outer frame has a first through hole in its middle, and the surface of the outer frame is inclined towards the first through hole in the middle. Several fixing brackets are provided at the edge of the first through hole. The panel light is fixed on the fixing brackets, and a ventilation groove is left between the panel light and the outer frame. The panel light includes a front frame, an LED light source, and a back cover. The front frame has a second through hole in its middle, and the LED light source is located on the inner side of the front frame. A light guide plate assembly is installed inside the front frame. The back cover is installed on the rear side of the front frame, and a power supply box is provided on the back cover. The power supply box is covered with a power cover, and the back cover and the power supply box are integrally injection molded. A power supply is provided inside the power supply box, and the power supply is electrically connected to the LED light source.

[0006] The aforementioned rear cover has a raised surface, and the power supply cover is located on the raised surface.

[0007] The light guide plate assembly described above includes a lampshade plate, a light guide plate, and a reflector plate, which are arranged and installed sequentially within the front frame.

[0008] The aforementioned fixing bracket is provided in four parts. Each fixing bracket includes a support plate and a connecting platform. One end of the support plate is connected to the panel light, and the other end of the support plate is connected to the connecting platform. The connecting platform is fixedly connected to the back cover.

[0009] The power supply cover described above is provided with a first wire hole.

[0010] The aforementioned rear cover is provided with a second wire hole.

[0011] A heat dissipation adhesive is provided between the LED light source and the front frame as described above.

[0012] Compared with the prior art, this utility model has the following advantages:

[0023] like Figures 1 to 5As shown, this embodiment provides a waterproof and dustproof exhaust fan light panel, including an outer frame 1 and a panel light 2. The outer frame 1 has a first through hole 101 in its center. The surface of the outer frame 1 is inclined towards the first through hole 101. Several fixing brackets 11 are provided at the edge of the first through hole 101. The panel light 2 is fixed to the fixing brackets 11, and a ventilation slot is provided between the panel light 2 and the outer frame 1. When the fan exhausts air, the air passes through the ventilation slot to the first through hole 101. The panel light 2 includes a front frame 21, an LED light source 22, and a back cover 23. A second through hole 210 is provided in the center of the front frame 21, and the LED light source 22 is disposed within the inner portion of the front frame 21. On the side, a light guide assembly 24 is installed inside the front frame 21. The LED light source 22 emits light from the side, which is then illuminated by the light guide assembly 24. The rear cover 23 is installed on the rear side of the front frame 21. A power supply box 231 is provided on the rear cover 23, and a power supply cover 232 is placed on the power supply box 231. The rear cover 23 and the power supply box 231 are integrally injection molded. A power supply is provided inside the power supply box 231. The power supply is electrically connected to the LED light source 22. The power supply cover 232 fits snugly against the light guide assembly 24. This prevents water vapor from contacting the power supply when the exhaust fan is turned on, improves the sealing performance, and provides dust and water protection, prevents short circuits in the drive, and extends the service life.

[0024] Furthermore, the rear cover 23 is provided with a raised surface 233, which can hold the light guide plate assembly 24 in place to prevent the light guide plate assembly 24 from shaking. The power cover 232 is located on the raised surface 233.

[0025] Furthermore, the light guide plate assembly 24 includes a lampshade plate 241, a light guide plate 242, and a reflector plate 243. The lampshade plate 241, the light guide plate 242, and the reflector plate 243 are arranged sequentially and installed in the front frame. The lampshade plate 241 plays the role of projecting light, the light guide plate 242 can play the role of refracting light, and the reflector plate 243 can reflect light to the direction of the lampshade plate 241 to avoid light leakage.

[0026] Furthermore, four fixing frames 11 are provided. Each fixing frame 11 includes a support plate 111 and a connecting platform 112. One end of the support plate 111 is connected to the panel light 2, and the other end of the support plate 111 is connected to the connecting platform 112. The connecting platform 112 is fixedly connected to the back cover 23. The fixing frame 11 lifts the panel light 2 to reserve the ventilation slot and also plays a fixing role.

[0027] Furthermore, the power cover 232 is provided with a first wire hole 234, and the rear cover 23 is provided with a second wire hole 235. The LED light source extension wire enters the power box 231 through the first wire hole 234, and then the other end of the first wire hole 234 comes out and extends out of the outside through the second wire hole 235 of the rear cover 23.

[0028] Furthermore, a heat-dissipating adhesive is provided between the LED light source 22 and the front frame 21. The heat-dissipating adhesive can conduct heat and transfer heat to the front frame 21, and can also serve as an adhesive.

[0029] Existing exhaust fan lights installed in bathrooms use LED lights powered by a driver. However, the high humidity and poor sealing in bathrooms can easily cause short circuits in the driver, affecting the operation of the exhaust fan lights. This paper provides a waterproof and dustproof exhaust fan light panel. A power supply box 231 is mounted on the back cover 23, and a power supply cover 232 is placed on top of the power supply box 231. The back cover 23 and the power supply box 231 are integrally injection molded. A power supply unit is located inside the power supply box 231, and this power supply unit is electrically connected to the LED light source 22. The power supply cover 232 is fitted to the light guide assembly 24, thus preventing water vapor from contacting the power supply when the exhaust fan is started, improving sealing, preventing short circuits in the driver, and extending the service life.

[0030] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
