[0025] The slot 1 93 is wider than the sliding block 94 , wherein a group of conductive rings 116 close to the fixed ring 111 is electrically connected to the switch of the motor 5 , and a group of conductive rings 116 away from the fixed ring 111 is electrically connected to the switch of the electromagnet 917 . When the electromagnet 917 is energized, the electromagnet 917 can push the magnetic strip 914 toward the outside of the rotating sleeve 913 .

[0026] The air inlet groove 12 connects the inner cavity of the connecting shell 2 and the air jet port of the rotating shell 91 , and the gas will blow the turbofan 118 when passing through the air inlet groove 12 .

[0027] Specifically, by cooperating with the elastic strip 113 and the inclined slider 119, under the premise of using the wind-driven rotating shell 91, the heat dissipation in the inner cavity of the chassis 1 can be more uniform, and the heat dissipation can be concentrated, and it can be applied to situations where the installation positions of heat-prone components are different.

[0028] In another embodiment provided by the present invention, the identification mechanism 11 includes a striker 101 horizontally inserted into the inner wall of the connecting shell 2, the bottom end of the striker 101 is meshedly connected with a spur gear 104, and a rotating shaft 103 is fixedly connected at the center of the spur gear 104, a reset torsion spring is fixedly connected between the outer wall of one end of the rotating shaft 103 and the connecting shell 2, a pull rope 105 is wrapped around the outer wall of the other end of the rotating shaft 103, and the other end of the pull rope 105 is fixedly connected to a fixed plate 106, a lifting rod 102 is fixedly connected to the bottom end of the fixed plate 106, and the lifting rod 102 is inserted up and down in the fixed block 8, and the bottom end of the lifting rod 102 extends between the fixing ring 2 111 and the fixing ring 1 92.

[0029] The striker bar 101 is arranged near the middle of the filter screen 7 .

[0030] Specifically, the elastic potential energy of the elastic strip 113 can be converted into kinetic energy of the impact rod 101 rushing toward the middle of the filter 7, thereby hitting the middle of the filter 7 to shake off water and reduce moisture. This prevents the filter 7 from being blocked soon after being replaced. The filter 7 in the middle has too much moisture and moves upward without having time to remove the moisture, which will cause more dust to stick to the filter 7 and increase the humidity in the inner cavity of the chassis 1, thereby reducing the service life of components.

[0031] Working principle: When using the device, start the exhaust assembly 3 and the motor 5, the exhaust assembly 3 dissipates heat to the inner cavity of the chassis 1, the gas enters from the air inlet 4, passes through the upper part of the filter 7 near the air inlet 4, then passes through the air inlet slot 12 and the through slot 97, and finally is discharged from the jet port of the rotating shell 91, and then passes through the inner cavity of the chassis 1 and is discharged from the exhaust assembly 3. When the wind passes through the turbofan 118, the turbofan 118 will drive the rotating block 117 to rotate. Due to the centrifugal force, the inclined slide block 119 moves obliquely upward. When too much dust accumulates on the upper part of the filter screen 7, the air volume sucked into the air inlet slot 12 will decrease, the rotation speed of the turbofan 118 will decrease, and the centrifugal force will decrease. The inclined slider 119 slides downward due to gravity. When the upper end of the elastic strip 113 encounters the lifting rod 102 and the second fixing ring 111, the elastic strip 113 will rotate clockwise, and the upper end of the elastic strip 113 is located in the rotating slot 112. Then the elastic strip 113 and the inclined slider 119 are located on the inner side of the second fixing ring 111. At this time, the conductive block 114 and the adjacent The conductive strip 115 of the second fixing ring 111 is in conflict, so that the two conductive rings 116 near the second fixing ring 111 are connected, the motor 5 is started, and the filter screen 7 starts to rotate, so that the upper part of the filter screen 7 is replaced. When replacing, the air intake of the upper part of the filter screen 7 will increase to the maximum, so that the air intake is increased, the turbofan 118 rotates faster, the centrifugal force increases, and the inclined slider 119 moves in the direction away from the second fixing ring 111. The upper end of the elastic strip 113 will be squeezed by the inner wall of the bottom end of the second fixing ring 111, and the elastic strip 113 cannot rotate counterclockwise, so the elastic strip 113 will be squeezed downward. When the upper part of the filter screen 7 is completely replaced with a new one, the air volume becomes the maximum. At this time, the centrifugal force increases to a critical value, and the elastic strip 113 can be removed from the second fixing ring 111. The elastic strip 113 is provided to enable the filter screen 7 to be completely replaced each time without using an unnecessary driving device and a control system, and to prevent the filter screen 7 at a certain place from being continuously used without being cleaned, thereby ensuring that the air volume is in an optimal state. When the device is at a relatively low temperature, the exhaust assembly 3 only needs to turn on the low air volume mode. When the turbofan 118 rotates, the inclined slider 119 is in the rotating rod 95. The rotation of the inclined slider 119 can drive the rotating rod 95 to rotate synchronously. Then, through the transmission of the bevel gear 99, the lever 910 can periodically shift the fixed rod 911, so that the rotating shell 91 can rotate periodically. Under the action of the fixed torsion spring 98, the rotating shell 91 can be reset. The periodic rotation of the rotating shell 91 can make the air jet reciprocate up and down, so that the heat dissipation of the inner cavity of the chassis 1 can be more uniform when the load is low. When the device is under high load and the temperature is high, the air extraction component 3 turns on the high air volume mode, the turbofan 118 rotates faster suddenly, the centrifugal force increases, the inclined slider 119 continues to move away from the fixed ring 111, the inclined slider 119 and the elastic strip 113 continue to rotate, and when the elastic strip 113 moves to the notch 96, the elastic strip 113 can move to the outside of the fixed ring 1 92, and then the notch 1 93 and the sliding block 94 quickly overlap, so that the inclined slider 119 no longer drives the rotating rod 95 to rotate; When the elastic strip 113 moves to the slot 96, the air jet of the rotating shell 91 is at the uppermost position, and the rotating shell 91 is in the conductive block 114, which connects the conductive ring 116 away from the fixed ring 111, so that the electromagnet 917 is activated, and the magnetic strip 914 moves outward. At this time, the rotating shell 91 rotates downward due to the elastic force of the fixed torsion spring 98, and the connecting block 912 will conflict with the magnetic strip 914, so that the rotating shell 91 stops rotating. The air jet of the rotating shell 91 sprays air to the area with the highest heat generation, concentrates the air volume to dissipate heat, and prevents local components from being overloaded. When the electromagnet 917 is not activated, the magnetic strip 914 moves downward due to gravity. To the rotating sleeve 913, wherein the angle of the rotating sleeve 913 and the magnetic strip 914 can be adjusted by a bolt 916. Since the air jet is always at the top when the elastic strip 113 moves to the slot 2 96, the air jet is subsequently rotated downward to reset. Therefore, if the installation position of the heat-prone components is different, the air jet can always be directed to the heat-prone components when overloaded, thereby improving the versatility of the device. Under the premise of using the wind-driven rotating shell 91, the heat dissipation in the inner cavity of the chassis 1 can be made more uniform, and the heat dissipation can be concentrated, and it can be suitable for the situation where the installation position of the heat-prone components is different; It should be noted that the elastic strip 113 is an elastic member with a large friction force. When the upper end of the elastic strip 113 is in close contact with the inner wall of the fixing ring 1 92, friction force can be generated, and the greater the centrifugal force, the greater the force of the inclined slider 119 moving upward, and the elastic strip 113 is in closer contact with the fixing ring 1 92, so that the friction force of the elastic strip 113 can prevent the rotating block 117 from rotating too fast when the air volume suddenly increases, and prevent the rotating shell 91 from rotating too fast when the elastic strip 113 is separated from the notch 2 96, and is located at the bottom; When the area at the bottom of the filter 7 is cleaned and moved to the middle, the elastic strip 113 will move out from the inner side of the fixing ring 111. When the upper end of the elastic strip 113 just moves out from the inner side of the fixing ring 111, the elastic strip 113 is in a compressed state. Then the elastic strip 113 bounces clockwise, causing the fixing ring 1 92 to suddenly move upward. Through the transmission of the fixing ring 1 92, the fixing plate 106, the pull rope 105, the rotating shaft 103, the spur gear 104 and the impact rod 101, the elastic potential energy of the elastic strip 113 can be converted into the kinetic energy of the impact rod 101 rushing towards the middle of the filter 7, and then the middle of the filter 7 can be hit to remove water and reduce moisture, so as to prevent the filter 7 from being blocked again soon after the upper part of the filter 7 is replaced. The filter 7 in the middle has too much moisture and moves upward without time to remove the moisture, which will cause more dust to stick to the filter 7 and increase the humidity in the inner cavity of the chassis 1, thereby reducing the service life of components.
