[0002] Bathrooms, as spaces where moisture and odors easily accumulate, often feature exhaust fans combined with LED lights, serving both ventilation and lighting functions. However, existing bathroom exhaust fans with integrated LED lights commonly suffer from inconvenient installation and subsequent maintenance / replacement. Traditional exhaust fans often use bolts or complex snap-fit structures to fix the main body and mounting frame, as well as the LED light components and the exhaust fan body. Disassembly and assembly require tools like screwdrivers, making the process cumbersome. This not only increases the workload for installers but also greatly inconveniences users during later maintenance (such as replacing damaged LED lights or cleaning the inside of the exhaust fan). Furthermore, repeated disassembly and assembly can lead to wear and tear on the connecting structures, affecting the overall stability of the device. Therefore, there is an urgent need for a bathroom exhaust fan with integrated LED lights that allows for quick disassembly and assembly without additional tools and is easy to operate, thus overcoming the shortcomings of existing technology.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Please see Figures 1-8 This utility model provides a technical solution: a bathroom exhaust fan with LED lights, including a housing 1, a fan assembly 6 fixedly installed inside the housing 1, an air outlet 7 installed on the front of the housing 1, the air outlet end of the fan assembly 6 communicating with the inside of the air outlet 7, and an LED assembly 4 installed at the bottom of the housing 1. The LED assembly 4 is detachably mounted to the fan assembly 6 via an elastic buckle assembly 5, which fixes the core component fan assembly 6 inside the housing 1 to prevent the fan assembly 6 from loosening due to vibration during operation. The use of the elastic buckle assembly 5 to connect the LED assembly 4 and the fan assembly 6 allows the user to disassemble the LED assembly 4 without tools, making the operation convenient and simple. The elastic buckle assembly 5 includes a metal elastic sheet 501, a spring structure 502, a connecting post 503, and a limiting stop 504. The connecting post 503 and the limiting stop 504 are both fixedly installed on the LED assembly 4. One end of the metal elastic sheet 501 is fixedly connected to the connecting post 503 by bolts, and the other end is inserted into the limiting stop 504. The spring structure 502 is movably sleeved on the metal elastic sheet 501. Both ends of the spring structure 502 are inserted into the housing extension protrusion 601 on the outer wall of the fan assembly 6. The connecting post 503 and the limiting stop 504 are provided for installing the metal elastic sheet 501. By sleeved on the metal elastic sheet 501, it is convenient to assemble and replace the spring structure 502. The connection between the LED assembly 4 and the fan assembly 6 is achieved by using the end of the spring structure 502 to be inserted into the housing extension protrusion 601. The spring structure 502 is divided into three parts: a spring helical section 5021, a spring extension section 5022, and a spring snap-fit end 5023. The spring extension section 5022 is located between the spring helical section 5021 and the spring snap-fit end 5023. The spring helical section 5021 is movably sleeved on the metal elastic sheet 501. The spring snap-fit end 5023 is engaged in the housing extension protrusion 601. When installing the LED assembly 4, the two spring extension sections 5022 can be pinched by hand to bring the two spring snap-fit ends 5023 closer together, so that the two spring snap-fit ends 5023 can be engaged in the housing extension protrusion 601. When the spring extension section 5022 is released, the spring snap-fit end 5023 is still engaged in the housing extension protrusion 601. Inside, push the LED assembly 4 upward to push the spring clip end 5023 further into the housing extension protrusion 601, making the clip connection less likely to fall off. When it is necessary to remove the LED assembly 4, simply pull down the LED assembly 4 to make the spring structure 502 bear force. The force of the spring structure 502 is transmitted to the metal elastic sheet 501, causing one end of the metal elastic sheet 501 that is inserted into the limit stop 504 to lift up, thereby allowing the spring structure 502 to slide out from the metal elastic sheet 501, and the LED assembly 4 can be removed. Then pinch the spring extension section 5022 and pull down the spring clip end 5023 to remove the spring structure 502. Then install the spring structure 502 on the metal elastic sheet 501. The outer wall of the housing 1 is provided with a mounting groove 8, and the air outlet 7 extends out from the mounting groove 8. The end of the air outlet 7 located inside the housing 1 is provided with an integrally formed skirt 701. An external protrusion 702 is fixedly provided on the outer wall of the air outlet 7. The inner diameter of the mounting groove 8 is larger than the maximum point of the air outlet 7 and smaller than the skirt 701. The skirt 701 is located inside the housing 1, and the external protrusion 702 is located outside the housing 1. Because the maximum point of the air outlet 7 is smaller than the inner diameter of the mounting groove 8, when assembling the air outlet 7, the air outlet 7 can be tilted through the mounting groove 8 so that the external protrusion 702 on the air outlet 7 can pass through the mounting groove 8. After the air outlet 7 is aligned, the skirt 701 and the external protrusion 702 can block the inner and outer walls of the housing 1. Then, the fan assembly 6 is installed inside the housing 1. At this time, the air outlet end of the fan assembly 6 abuts against the air outlet 7 so that the air outlet 7 will not fall off from the mounting groove 8. LED assembly 4 includes LED panel frame 401 and ventilation connecting bracket 402. Ventilation connecting bracket 402 is set on the top of LED panel frame 401 and is fixedly connected to LED panel frame 401 by screws. A light-transmitting panel 403 is set at the bottom of LED panel frame 401. Ventilation connecting bracket 402 is set to leave an air intake channel between the bottom of housing 1 and LED panel frame 401 to ensure that fan assembly 6 can draw air out of the bathroom. LED panel frame 401 serves as a mounting bracket for LED lights. Light-transmitting panel 403 is used to transmit light and protect the LED lights at the bottom of LED panel frame 401. Mounting bracket 1 2 is fixedly installed on the back of the box 1 with screws, and mounting bracket 2 3 is fixedly installed on the front of the box 1. Mounting bracket 1 2 and mounting bracket 2 3 are used to connect the box 1 to the wall or ceiling. A one-way valve is installed inside the air outlet 7. The air inlet end of the fan assembly 6 faces the LED assembly 4. The one-way valve is installed to prevent external garbage and other objects from entering the fan assembly 6 in reverse. The air inlet end of the fan assembly 6 faces the LED assembly 4 so that it is directed towards the air inlet channel on the ventilation connecting frame 402 to ensure air extraction efficiency. A speed control switch 9 is fixedly installed inside the housing 1. An operation window 10 is provided on the front of the housing 1. The operating end of the speed control switch 9 extends into the operation window 10. The speed control switch 9 is used to adjust the speed of the fan assembly 6, thereby adjusting the ventilation power. The operation window 10 is provided to facilitate the user to operate the speed control switch 9 from outside the housing 1.
[0017] Working principle: In use, first tilt the air outlet 7 so that it passes obliquely through the mounting groove 8. Then straighten the air outlet 7, and the skirt 701 and the external protrusion 702 will block the inner and outer walls of the housing 1. Then install the fan assembly 6 inside the housing 1. At this time, the air outlet end of the fan assembly 6 abuts against the air outlet 7, so that the air outlet 7 will not fall out of the mounting groove 8. Invert the housing 1, and then pinch the spring extension section 5022 to bring the two spring clip ends 5023 closer together so that the two spring clip ends 5023 can be engaged. When the spring extension section 5022 is released into the housing extension protrusion 601, the spring clip end 5023 remains locked inside the housing extension protrusion 601. Then, push the LED component 4 upward to push the spring clip end 5023 further into the housing extension protrusion 601, making the clip connection less likely to fall off, thus completing the installation of the LED component 4. Place the box 1 in the exhaust area of the bathroom, and use mounting bracket 1 2 and mounting bracket 2 3 to fix the box 1 to the wall or ceiling, thus completing the assembly and installation of the bathroom exhaust fan.
[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
