Lift plate 16 is connected to baffle 6 via connecting rod 4, thereby driving baffle 6 to move. The movement of baffle 6 partially or completely blocks air inlet holes 20 on the surface of air inlet cover 7, enabling adjustment of the air intake volume and further precise control of ventilation effect. Example 2
[0018] See also Figure 1 and Figure 2 , provides the following technical solutions, specifically disclosed: the bottom of the outer side of the frame 3 is fixedly connected to the battery box 13 by bolts, the inner cavity of the battery box 13 is fixedly connected to the battery 14 by bolts, and a charging port 15 is provided at the middle end of one side of the battery box 13, and the output end of the charging port 15 is electrically connected to the input end of the battery 14 in one direction, a sliding rod 12 is fixedly connected to one side of the frame 3, and the surface of the sliding rod 12 is slidably connected to one side of the inner cavity of the lifting plate 16, a heat dissipation pipe 9 is fixedly connected to the right side of the fan body 8, and a dustproof net 10 is fixedly connected to the surface of the heat dissipation pipe 9 by bolts, and an air filter 18 is fixedly connected to the middle end of the lifting plate 16 by bolts, and a filter hole 19 is provided on the surface of the air filter 18, and a timing controller 2 is fixedly connected to the outer side of the frame 3 by bolts, and the output end of the timing controller 2 is electrically connected to the input end of the fan body 8 in one direction, and mounting holes are provided around the bottom plate 1, and the mounting holes are circular structures; During actual use, the air filter 18 installed at the middle end of the lifting plate 16 and the filter holes 19 on the surface are used to filter the air before it enters the fan body 8, removing dust, impurities, etc. in the air, ensuring the quality of the air entering the fan, reducing dust accumulation inside the fan, and extending the service life of the fan. Through the one-way electrical connection between the timing controller 2 and the fan body 8, the user can set the ventilation time of the fan according to actual needs, realize automatic ventilation control, meet the ventilation requirements in different scenarios, and improve energy utilization efficiency. The heat dissipation pipe 9 on the right side of the fan body 8 helps to dissipate the heat generated during the operation of the fan and ensure the normal operating temperature of the fan. The dustproof net 10 on the surface of the heat dissipation pipe 9 can prevent dust and other impurities from entering the heat dissipation pipe 9 and affecting the heat dissipation effect.
[0019] During use: the output end of the charging port 15 is electrically connected to the input end of the battery 14 in a one-way manner, and the electric energy of the external power supply can be transmitted to the battery 14 for charging through the charging port 15. The battery 14 provides power support for electrical equipment such as the motor 5 and the fan body 8. The user sets the operating time of the fan body 8 by operating the timing controller 2. The output end of the timing controller 2 is electrically connected to the input end of the fan body 8 in a one-way manner. When the set time is reached, the timing controller 2 controls the fan body 8 to stop running, realizes the adjustment of the ventilation time, starts the motor 5, and the output end of the motor 5 drives the threaded rod 17 to rotate. Since the lifting plate 16 is threadedly connected to the threaded rod 17, and one side of the inner cavity of the lifting plate 16 is slidably connected to the slide rod 12, the rotation of the threaded rod 17 will cause the lifting plate 16 to move up and down along the slide rod 12. Lifting plate 16 drives baffle 6 via connecting rod 4. During this movement, baffle 6 partially or completely blocks air inlet holes 20 on the surface of air inlet hood 7, thereby regulating the amount of air entering fan body 8. When air enters air inlet hood 7 through air inlet holes 20, it first passes through air filter 18. Filter holes 19 filter out dust and impurities in the air. The filtered air then enters fan body 8. Heat generated during operation of fan body 8 is dissipated through heat pipe 9. Dust screen 10 prevents dust from entering heat pipe 9 and affecting the heat dissipation effect.
