when the pushing member 24 is in use, namely the fan blade 222 starts to rotate, the waste heat gas flows towards the direction of the air outlet part 213, the incomplete gear 241 then follows the fan blade 222 to rotate synchronously, when the teeth on the incomplete gear 241 rotate to be just meshed with the teeth on the rack 244, the rack 244 can be driven to start moving, the rack 244 synchronously moves horizontally under the limiting action of the limiting rod 243 and extrudes the reset spring 245 to shrink, the pushing plate 242 then synchronously starts sliding along with the rack 244, when the pushing plate 242 slides, the waste heat gas at the moving direction position can be pushed forwards, so that the flow speed of the waste heat gas is accelerated, when the incomplete gear 241 continues to rotate, the teeth on the incomplete gear 241 are not meshed with the rack 244 any more, the rack 244 can be driven to slide horizontally under the elastic action of the reset spring 245, the pushing plate 242 also follows reset, the teeth on the incomplete gear 241 rotate to be meshed with the rack 244, the rack 244 slides again, the pushing plate 242 can reciprocate horizontally, the pushing plate 242 can continuously pushes the gas in the moving direction, the waste heat gas can be pushed forwards, the moving direction of the pushing plate 242 can be pushed along with the moving direction, and the negative pressure can be kept to be a certain extent, when the sliding plate 242 is required to be pushed to slide along with the opposite side walls, and the sliding plate 21 can be pushed, and the negative pressure can be normally, and the problem can be prevented from being pushed to slide along with the sliding plate can be caused by the sliding plate 21;
through setting up this pushing component 24, mainly used further quickens waste heat gas flow rate, wherein, through setting up incomplete gear, rack 244, pushing plate 242, reset spring 245 and gag lever post 243 cooperation use, can make incomplete gear 241 synchronous drive pushing plate 242 reciprocating motion in sealed cowling body 21 when rotating motor 221 drive flabellum 222, and utilize the reciprocating motion of pushing plate 242 can promote the waste heat gas who keeps away from flabellum 222 position, thereby quicken waste heat gas's flow rate, be favorable to promoting waste heat gas to flow to the portion 213 position fast, in order to reach the purpose that further promotes waste heat gas flow rate.
As an embodiment of the present invention, in the above technical solution, since a certain gap is left between the two ends of the pushing plate 242 and the inner side wall of the sealing cover 21, when the pushing plate 242 pushes the waste heat gas, the pushing force generated by the air flow is weakened, so in order to solve the problem, the improvement is specifically: the two ends of the pushing plate 242 closely slide with two sides of the inner side wall of the sealing cover body 21, one side of the pushing plate 242 close to the fan blade 222 is provided with a passing component 25, the passing component 25 is in a conical structure, the tip end of the passing component 25 faces the direction of the fan blade 222, the passing component 25 comprises a plurality of elastic plectrum groups 251 and a plurality of passing holes 252, the end parts of the plectrum in the plectrum groups 251 are fixedly connected with one side of the pushing plate 242, the passing holes 252 are communicated with one side of the pushing plate 242, the plectrum groups 251 are in one-to-one correspondence with the passing holes 252, and the plectrum can be a plastic sheet;
in the process that the pushing plate 242 approaches to the fan blade 222, the generated air flow is opposite to the tip of the passing component 25, so that the pulling piece is not enabled to move, the pulling piece is in a closed state at the moment, the passing hole 252 is blocked, two ends of the pushing plate 242 are tightly and slidably attached to the inner side wall of the sealing cover body 21, in the process that the pushing plate 242 slides, the air passing through the pushing plate 242 can be greatly reduced, further the pushing plate 242 generates a larger pushing force on the waste heat air in the moving direction, the flowing speed of the hot air is accelerated, and when the pushing plate 242 slides and resets, because the generated air flow is opposite to the opening of the passing component 25 at this time, the air flow can enter the inner side of the passing component 25, and because the poking plate is an elastic sheet and has lighter weight, the passing component 25 is finally in an opened state when the air flow passes, so that the air flow can smoothly pass through the pushing plate 242, the problem that the pushing plate 242 compresses the air is avoided, the pushing plate 242 can smoothly reset, and after the pushing plate 242 reaches the initial position, the poking plate is finally reset by means of self elastic force due to no air flow effect, so that the passing component 25 is in a closed state;
the through part 25 is arranged on the pushing plate 242 and is mainly used for increasing the pushing force of the pushing plate 242, and the through hole 252 and the poking piece are used in a matched mode, so that when the pushing plate 242 pushes waste heat gas to approach to the direction of the fan blade 222, the waste heat gas is in a closed state, the problem that the pushing force is weakened due to the fact that the gas passes through the pushing plate 242 is solved, the pushing effect of the pushing plate 242 pushing the waste heat gas is further improved, and the waste heat gas is enabled to flow towards the direction of the air outlet part 213 rapidly; meanwhile, when the pushing plate 242 is reset, the passing component 25 is opened under the action of the air flow, so that the air can smoothly pass through the pushing plate 242, and the problem of negative pressure caused by compressed air when the pushing plate 242 is reset is avoided.
