A spring 96 is provided on the outside of the fixing rod 95.

By designing the spring 96, the force of the spring 96 can act on the slider 97.

[0025] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 The outer side of the fixed rod 95 is slidably sleeved with a slider 97, and the slider 97 is slidably connected to the connecting frame 91.

[0026] The specific implementation process of this utility model is as follows: During use, the mainboard 10 houses a single-chip microcomputer and a Lin communication transceiver. The single-chip microcomputer is responsible for driving the brushless motor and processing communication signals, while the transceiver is responsible for signal reception and forwarding. When the transceiver first receives a signal, it wakes up the single-chip microcomputer and sends a signal. The single-chip microcomputer interprets the Lin signal to obtain the corresponding instruction, driving the motor and rotor 11 to rotate and produce air. If the single-chip microcomputer times out for 5 seconds without receiving any information, it automatically stops the motor and enters a dormant state.

[0027] Through the action of the connecting frame 91 and the filter 92, the fan outlet can be dustproof to avoid the entry of dust. Under the action of the flow channel 991, the air will first flow inside the flow channel 991 before being blown out.

At the same time, with the action of the sound-absorbing cotton 992, the purpose of silencing and reducing the noise of the gas can be achieved.

[0028] When the connection frame 91 needs to be disassembled, the slider 97 is pushed downward, and the slider 97 slides along the fixed rod 95 to squeeze the spring 96. At the same time, the slider 97 drives the plug block 98 to move downward so that the plug block 98 is separated from the slot 99. Then, the connection frame 91 is moved horizontally, and the connection frame 91 drives the dovetail block 93 to slide along the dovetail groove 94. The connection frame 91 can be pulled out and removed from the bottom shell 1 and the upper shell 2, thereby facilitating the maintenance and use of the filter 92 and the noise reduction components.
