[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] In the technical solution of this utility model, Figures 1, 2, and 3 are structural schematic diagrams provided by the intelligent voice ventilation fan of this utility model. As shown in Figures 1, 2, and 3, this utility model includes:

[0021] The system comprises an opening and closing mechanism 2, an opening and closing top cover 3, a mounting base 1, and a control module 4. The length of the opening and closing top cover 3 is greater than the length of the mounting base 1. The two sides of the opening and closing top cover 3 are hinged to the two sides of the mounting base 1. An air exchange filter 31 is provided at the front end of the opening and closing top cover 3, which is used for filtration during air exchange. The rear end of the opening and closing top cover 3 covers the top of the mounting base 1. The middle part of the mounting base 1 is a ventilation area 11, and the surrounding area is a mounting area 12. A fan module 5 is provided in the ventilation area 11, and the fan module 5 is connected to the control module 4. The top end of the opening and closing mechanism 2 is connected to the opening and closing top cover 3, and the bottom end of the opening and closing mechanism 2 is installed in the mounting area 12. The opening and closing mechanism 2 is used to lift the opening and closing top cover 3. The control module 4 is installed on a mounting plate 6, which is installed at the bottom of the mounting base 1 and spaced apart from the mounting base 1. The gap between the mounting plate 6 and the mounting base 1 provides a channel for gas flow.

[0022] As shown in Figure 5, the control module 4 includes a voice recognition module 41, a microphone module 42, and a main control module 43. The voice recognition module 41 is connected to the microphone module 42, and the main control module 43 is connected to the opening / closing mechanism 2 and the fan module 5. The microphone module 42 is used to collect the user's voice. The voice recognition module 41 can recognize the voice and send it to the main control module. Specifically, the voice recognition module can use a module with a voice recognition chip, such as an LD3320. The main control module, based on the voice recognition results, can use a microcontroller to control the opening / closing mechanism 2 and the fan module 5. The voice commands specifically control functions such as turning the fan on and off, opening and closing the lid, fan acceleration / deceleration, fan suction / extraction, and turning the lights on and off.

[0023] In one embodiment of this utility model, the opening and closing mechanism 2 includes an opening and closing motor 21, an opening and closing rotating shaft 22, and an opening and closing arm 23. One end of the opening and closing arm 23 is mounted on the opening and closing rotating shaft 22, and the other end is connected to the opening and closing top cover 3. The opening and closing rotating shaft 22 is mounted in the mounting area 12 of the mounting base 1, and one end of the opening and closing rotating shaft 22 is connected to the output end of the opening and closing motor 21. The opening and closing motor 21 is connected to the main control module 43. In the closed state, the top of the side wall of the mounting base 1 is in contact with the opening and closing top cover. At this time, the area at the front end of the opening and closing top cover 3 is isolated from the interior of the mounting base 1, i.e., the exterior is isolated from the interior and is in a closed state. After the opening and closing top cover is lifted, the area at the front end of the opening and closing top cover 3 is connected to the interior of the mounting base 1, achieving ventilation. During rotation, the opening and closing mechanism forms a triangular stable space with the opening and closing top cover, thereby stably opening or closing the opening and closing top cover and providing stable support for it. Among them, the opening and closing motor 21 is a geared motor, including a motor body and a reducer. This technology is a conventional technology in this field, so it will not be described in detail here.

[0024] In one embodiment of this utility model, the fan module 5 includes a fan impeller 51 and a fan motor 52. The fan impeller 51 is located in the ventilation zone 11, and the hub of the fan impeller 51 is mounted on the motor shaft of the fan motor 52. The fan motor 52 is vertically mounted in the space between the opening and closing top cover 3 and the mounting base 1. Vertical mounting can effectively reduce the space occupied by the motor. The fan impeller includes a hub, and several blades are spaced apart on the inner circumference of the hub. Each blade is inclined at 40° on the hub and twists 20° around its stalk. The cross-section of the blade is arc-shaped, and the blade extends radially towards the center of the hub. The forward and reverse rotation of the impeller can change the airflow direction of the ventilation fan. Therefore, the ventilation fan can be used as a regular cooling fan or as a ventilation fan to ventilate the space and ensure air circulation. The method of controlling the forward and reverse rotation and speed of the motor with a microcontroller is a conventional technique in the art and will not be described in detail here.

[0025] In one embodiment of this utility model, as shown in FIG. 4, a lighting lamp 61 is mounted at the center of the mounting plate 6. The lighting lamp 61 is connected to a relay 63, and the control terminal of the relay 63 is connected to a main control module 43. The main control module 43 is connected to a switch button 48 for turning the lighting lamp 61 on / off. The input terminal of the relay is connected to a power supply. The switch button 48 can provide signals to turn the lighting lamp 61 on and off, and the main control module 43 can also control the lighting lamp according to the signals from the voice recognition module. Ventilation holes are provided around the mounting plate 6 to provide a gas flow channel.

[0026] In one embodiment of the present invention, the control module 4 further includes: a raindrop sensor 44, a temperature sensor 45, a motor control button 46 for adjusting the speed and direction of rotation of the fan module 5, and an opening / closing control knob 47 for starting / stopping the opening and closing mechanism 2. The motor control button 46, the opening / closing control knob 47, the raindrop sensor 44, and the temperature sensor 45 are connected to the main control module 43.

[0027] The rain sensor 44 can detect whether it is raining and the amount of rain, while the temperature sensor 45 is used to detect the temperature inside the vehicle. The main control module 43 reads the temperature data collected by the temperature sensor 45 and compares it with the preset temperature data. If the collected temperature data is higher than the preset temperature data, the main control module 43 controls the fan motor 52 of the fan impeller 51 to start, causing the fan impeller 51 to rotate. At the same time, it controls the opening and closing motor 21 to start, controlling the opening and closing mechanism 2 to lift, so as to open the opening and closing top cover 3.

[0028] In one embodiment of this utility model, the control module 4 further includes a signal receiving module 49, which is connected to the main control module 43 and is used to receive control signals from the remote controller. Remote control can then be achieved via the remote controller.

[0029] In one embodiment of this utility model, a decorative frame 7 is connected to the bottom of the mounting base 1. The assembled ventilation fan body is installed in the decorative frame 7, which not only serves a decorative and aesthetic purpose but also prevents the impeller 3 from touching other objects during rotation, thus providing a safety protection function.

[0030] The practical application process of this utility model is as follows: Users can open and close the top cover, ventilate, turn lights on and off, and adjust the wind speed by voice or button. The intelligent ventilation fan can also be automatically controlled by temperature sensors and raindrop sensors in conjunction with the internal program.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
