Description

Technical Field

[0001] This utility model relates to the field of ventilation fan technology, and in particular to wall-mounted ventilation fans. Background Technology

[0002] Traditional exhaust fans have a relatively simple function, mainly realizing the exchange of indoor and outdoor air and only meeting basic ventilation needs. With the improvement of people's quality of life and the development of the influencer economy, users have higher requirements for the function and appearance of exhaust fans, hoping that they can not only complete the ventilation function, but also integrate lighting, audio playback and other functions, becoming a home appliance that combines practicality and decoration.

[0003] Currently, although some ventilation fan products with integrated lighting or sound systems have appeared on the market, they are lacking in terms of intelligent function control and heat dissipation of internal electronic components. On the one hand, the control of functions such as lighting and sound is independent of the control of the ventilation fan itself, lacking a unified intelligent control system, which makes it inconvenient for users to operate. On the other hand, after integrating multiple functions, the main control board, control board and other electronic components inside the ventilation fan will generate a lot of heat during operation. If the heat dissipation is not good, it will affect the performance and lifespan of the electronic components, and may even pose safety hazards. Utility Model Content

[0004] To overcome existing problems, this application provides a wall-mounted ventilation fan that integrates light strips and speaker modules, and sets up a collaborative control structure between the main control board and the control board to achieve intelligent and unified control of lighting, sound, and ventilation functions. At the same time, the air duct structure is used to dissipate heat from the main control board, solving the heat dissipation problem of electronic components and improving the stability and service life of the product.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A wall-mounted exhaust fan includes a protective shell, a panel, a cover, a horn, and a heat dissipation assembly. The protective shell protects the internal components of the exhaust fan and prevents external debris from entering. The mounting plate is used to fix the exhaust fan to the wall. The panel serves both decorative and partial protective functions.

[0007] The protective shell has a fixing plate on its outer wall with multiple mounting holes for fixing to the wall with expansion screws. The protective shell and the heat dissipation assembly are connected by snaps. The other side of the fixing plate is connected to the panel. The face shield is built into the face shield and has a light strip around its perimeter. A speaker is embedded in the face shield and a control board is located on the back of the speaker. The speaker, light strip, and control board are detachable modules. The main control board has a reserved expansion interface for connecting external sensors or smart devices. The main control board is equipped with a power management module for controlling the low-power operation of the ventilation fan in standby mode.

[0008] The heat dissipation assembly includes a housing with an air duct at its top. The inner wall of the air duct has arc-shaped guide vanes to enhance the heat dissipation effect of the airflow on the main control board. The main control board is housed inside the air duct and integrates environmental sensors, including at least one of a temperature and humidity sensor and a PM2.5 sensor. The main control board automatically adjusts the fan speed based on the detection data from the environmental sensors. The main control board is used to control the control board to regulate the operation of the light strip and the speaker. The main control board is installed inside the air duct and located in the airflow path generated by the motor. The outer wall of the main control board has a protective plate. The airflow from the air duct during fan operation cools the main control board, effectively solving the heat dissipation problem during operation and ensuring stable operation. The main control board can control the control board by sending control signals to adjust the light color and brightness of the light strip and the volume and playback mode of the speaker, thereby achieving multi-functional intelligent unified control.

[0009] Preferably, the heat dissipation component is located inside the outer casing and further includes a heat dissipation shell, in which a motor is installed.

[0010] Preferably, the light strip is an RGB light strip, and the control board is used to receive instructions from the main control board to adjust the color, brightness and flashing mode of the light strip, which can provide lighting and decorative effects and enrich the product's functionality and visual experience.

[0011] Preferably, the speaker has a built-in Bluetooth module, and the control board is used to receive instructions from the main control board to control the speaker's audio playback, pause, volume adjustment, and playback mode switching, thereby realizing audio playback function and meeting the user's entertainment needs during ventilation.

[0012] The advantages of the embodiments of this application are:

[0013] 1. It integrates lighting, audio playback and ventilation functions into one unit. Through the main control board, the control board can be operated to realize intelligent and unified control of lighting, sound and ventilation functions. It is easy to operate and meets the diverse needs of users.

[0014] 2. The main control board is located inside the air duct and is cooled by the airflow generated by the ventilation fan. At the same time, the external protective plate can prevent debris from entering and affecting the heat dissipation and normal operation of the main control board, effectively improving the heat dissipation effect of the main control board, ensuring the performance and service life of electronic components, and improving the stability and safety of the product.

[0015] 3. The light strip around the faceplate can provide a variety of lighting effects, making the exhaust fan both practical and decorative, and better able to blend into different interior decoration styles, meeting the needs of users in the influencer economy for product appearance and personalization.

It can better integrate into different interior decoration styles and meet the needs of users in the influencer economy for product appearance and personalization.

[0025] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0026] Example

[0027] This embodiment provides the specific structure of the wall-mounted ventilation fan, such as... Figure 1-5As shown, it includes a protective shell 1, a panel 3, a face shield 4, a speaker 5, and a heat dissipation assembly 6. The protective shell 1 is used to protect the various components inside the ventilation fan and prevent external debris from entering; the fixing plate 2 is used to fix the ventilation fan to the wall; the panel 3 serves a decorative and partial protective function.

[0028] The protective shell 1 has a fixing plate 2 on its outer wall. The fixing plate 2 has multiple mounting holes and is fixed to the wall by expansion screws. The protective shell 1 is connected to the heat dissipation component 6 by a buckle. The other side of the fixing plate 2 is connected to the panel 3. The face shield 4 is built into the face shield 4. The face shield 4 has a light strip 8 around its perimeter. The face shield 4 has a speaker 5 embedded inside its interior. The back of the speaker 5 has a control board 7. The speaker 5, light strip 8 and control board 7 are detachable modules. The main control board 65 has a reserved expansion interface for connecting external sensors or smart devices. The main control board 65 is equipped with a power management module for controlling the low-power operation of the ventilation fan in standby mode.

[0029] The heat dissipation component 6 includes a housing 63, with an air duct 64 at the top. The inner wall of the air duct 64 is provided with arc-shaped guide vanes to enhance the heat dissipation effect of airflow on the main control board 65. The main control board 65 is located inside the air duct 64. The main control board 65 integrates environmental sensors, including at least one of a temperature and humidity sensor and a PM2.5 sensor. The main control board 65 automatically adjusts the fan speed based on the detection data of the environmental sensors. The main control board 65 is used to control the control board 7 to adjust the operation of the light strip 8 and the speaker 5. The main control board 65 is installed inside the air duct 64 and located in the airflow path generated by the motor 61. The outer wall of the main control board 65 is provided with a protective plate. The airflow in the air duct during the operation of the fan cools the main control board 65, effectively solving the heat dissipation problem of the main control board 65 during operation and ensuring its stable operation. The main control board 65 can control the control board 7 by sending control signals to control the light color and brightness of the light strip 8 and the volume and playback mode of the speaker 5, thereby realizing multi-functional intelligent unified control.

[0030] The heat dissipation component 6 is located inside the outer casing 63 and also has a heat dissipation shell 62, in which a motor 61 is installed.

[0031] The light strip 8 is an RGB light strip. The control board 7 is used to receive instructions from the main control board 65 to adjust the color, brightness and flashing mode of the light strip 8, which can provide lighting and decorative effects, and enrich the product's functions and visual experience.

[0032] The speaker 5 has a built-in Bluetooth module, and the control board 7 is used to receive instructions from the main control board 65 to control the audio playback, pause, volume adjustment and playback mode switching of the speaker 5, so as to realize the audio playback function and meet the entertainment needs of users during ventilation.

[0033] By adopting the above technical solution:

[0034] The light strip 8 uses RGB light strips and supports 16 million color adjustment through the control board 7. Lighting effects such as "ambience mode" and "energy saving mode" can be preset through the main control board 65.

[0035] Speaker 5 is a 5W full-range speaker with a built-in Bluetooth module. Control board 7 receives commands from main control board 65 to switch music playback, pause, volume adjustment and other functions.

[0036] The air duct 64 adopts a straight cylindrical design, and the main control board 65 is horizontally installed in the middle of the air duct 64. The protective plate is a hollow metal mesh to ensure that the wind blows directly on the surface of the main control board 65.

[0037] The user sends commands to the main control board 65 via a mobile app. After parsing the commands, the main control board 65 sends corresponding signals to the control board 7.

[0038] If the instruction is "Turn on ambient lighting", adjust the light strip 8 on control panel 7 to a warm yellow gradient mode;

[0039] If the command is "play music", the control board 7 will initiate a Bluetooth connection, receive audio signals, and drive the speaker 5 to play the music.

[0040] Meanwhile, when the ventilation fan is running, the airflow in the duct 64 continuously passes through the main control board 65, carrying away heat.

[0041] The main control board integrates environmental sensors (temperature, humidity, and PM2.5 sensors) to automatically adjust the ventilation fan speed based on indoor air quality.

[0042] The light strip 8 and the speaker 5 support "scene linkage": when the indoor smoke concentration is detected to be too high, the main control board 65 controls the light strip 8 to flash red light, the speaker 5 to sound an alarm, and automatically turns on the strong wind ventilation mode.

[0043] The air duct 64 adopts a spiral airflow design, with arc-shaped airflow guide vanes set on the inner wall of the air duct 64 to enhance the heat dissipation effect of the airflow on the main control board 65.

[0044] First, fix the fixing plate 2 in a suitable position on the wall. Multiple mounting holes can be provided on the fixing plate 2, and it can be firmly connected to the wall by expansion screws and other connectors.

[0045] Install the motor 61 in a suitable position inside the heat sink 62. The motor 61 and the heat sink 62 are connected by screws and other fasteners to ensure stable operation of the motor 61.

[0046] The main control board 65 is installed inside the air duct 64, and a protective plate is installed. The protective plate is fixed to the inner wall of the air duct 64 by means of clips or screws to ensure that the main control board 65 is within the effective heat dissipation area of ​​the air duct 64 and that the protective plate can provide good protection.

[0047] A speaker 5 is installed inside the mask 4. The speaker 5 is connected to the mask 3 by means of adhesive or screws to ensure that the speaker 5 is firmly installed. A control board 7 is installed on the back of the speaker 5. The control board 7 is connected to the speaker 5 by wires to realize signal transmission and control.

[0048] Light strips 8 are installed around the mask 4. The light strips 8 are installed on the mask 4 by means of adhesive or clips. The light strips 8 are connected to the control board 7 by wires so as to receive control signals.

[0049] Finally, the protective shell 1 is installed on the outside of the entire ventilation fan. The protective shell 1 is fixedly connected to the heat dissipation component 6, panel 3, etc. by means of clips or screws, thus completing the installation of the wall-mounted ventilation fan.

[0050] When the ventilation fan is running, the motor 61 drives airflow, creating airflow within the duct 64. The main control board 65 is connected to the control board 7 via wires, sending control signals. The control board 7 then controls the lighting effects of the light strip 8 and the audio playback of the speaker 5 based on these signals. Simultaneously, the airflow within the duct 64 blows against the main control board 65, dissipating heat and ensuring stable operation. Users can send commands to the main control board 65 via remote control, mobile app, or the control panel integrated into the ventilation fan to operate and adjust various functions of the fan.

[0051] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
