The working process of the example is as follows:
initially, referring to fig. 2, 3 and 4, when the motor 1 is started in use, the temperature of the motor 1 does not change, the motor 1 rotates clockwise (from the top view in fig. 2), and the motor shaft 101 drives the fixing disc 8 to rotate clockwise. Because the volumes of the alcohol in the telescopic cylinder outer cylinder 9 and the telescopic cylinder inner cylinder 10 are not changed, the telescopic cylinder inner cylinder rotating block 1001 of the telescopic cylinder inner cylinder 10 is clamped below the second clamping block 903 of the telescopic cylinder rotating block positioning groove 901 of the telescopic cylinder outer cylinder 9, the fixed disk 8, the telescopic cylinder inner cylinder 10 and the connecting rod 6 are relatively fixed, at the moment, the connecting rod main rod 602 is inclined by a certain angle, and at the moment, the spiral angle of the fan blade 3 cannot be changed. In the initial state, the fixed disk 8 drives the fan blades 3 to rotate clockwise through the connecting rods 6. When the motor shaft 101 rotates clockwise, the torsion spring drives the rotating frame 2 to rotate clockwise, and due to the action of inertia, the torsion spring is compressed, the rotating frame rotates with respect to the motor shaft in a lagging manner, when the motor 1 reaches a rated rotating speed, the torsion spring releases certain elasticity, the rotating frame 2 rotates synchronously with the fan blades 3, the reversing exhaust fan draws air upwards, outside air is forced to enter the evaporative condenser 41 from the air inlet 27, and saturated hot and humid air in the evaporative condenser 41 is exhausted to the surrounding atmosphere through the air outlet 42.
Since the hot and humid air passes through the telescopic cylinder, the alcohol in the telescopic cylinder is gradually evaporated after being heated, but the telescopic cylinder inner cylinder rotating block 1001 is limited by the second clamping block 903 in the rotating block positioning groove 901 at the initial stage of evaporation, and cannot move upwards. Along with the increase of temperature, the alcohol evaporation capacity in the telescopic cylinder is bigger and bigger, and pressure intensity is constantly increased, and when pressure intensity was big enough, the rotatory piece 1001 of telescopic cylinder inner tube overcome elastic force and surpassed second clamp block 903 rebound earlier, when contacting first clamp block 902, because the inboard angle of first clamp block 902 is less for the rotatory piece 1001 of telescopic cylinder inner tube can pass first clamp block 902 smoothly, and the card is in the rear side of first clamp block 902. In the process that the telescopic cylinder inner cylinder 10 moves upwards, the rotating disc 7 is driven to gradually approach the fixed disc 8, the inclination angle of the connecting rod main rod 602 is larger and larger, the second rotating rod 5 moves upwards, the first rotating rod 4 moves downwards, and the rotating direction of the fan blades 3 is smaller and smaller; in the process of changing the connecting rod main rod 602, there is an intermediate transition state, as shown in fig. 5 and 6, in this state, the connecting line of the heads of the first rotating rod 4 and the second rotating rod 5 of the two connecting rods 6 corresponding end to end is parallel to the horizontal plane, and at this time, the rotation direction of the fan blade 3 tends to be horizontal; when the main connecting rod 602 is tilted further, the second rotating rod 5 moves further upwards and the first rotating rod 4 moves further downwards, so that the rotation direction of the fan blades changes to the opposite direction.
The reversing exhaust fan 32 blows air downwards to cool the motor 1 and the telescopic cylinder, but the telescopic cylinder inner cylinder rotating block 1001 is limited by the first clamping block 902 in the rotating block positioning groove 901 at the initial cooling stage, and cannot move downwards. Along with the decline of temperature, the alcohol evaporation capacity in the telescoping cylinder is littleer and more, and pressure intensity constantly reduces, and when pressure intensity was little enough, the rotatory piece 1001 of telescoping cylinder inner tube overcome the elastic force and surpass first clamp block 902 restriction and move down earlier, when contacting second clamp block 903, because the inboard angle of second clamp block 903 is less for the rotatory piece 1001 of telescoping cylinder inner tube can pass second clamp block 903 smoothly, and the card is in the rear side of second clamp block 903. In the process that the telescopic cylinder inner cylinder 10 moves downwards, the rotating disc 7 is driven to gradually approach the fixed disc 8, the inclination angle of the connecting rod main rod 602 is smaller and smaller, the second rotating rod 5 moves downwards, the first rotating rod 4 moves upwards, and the rotating direction of the fan blades 3 is smaller and smaller; in the process of changing the connecting rod main rod 602, there is an intermediate transition state, as shown in fig. 5 and 6, in this state, the connecting line of the heads of the first rotating rod 4 and the second rotating rod 5 of the two connecting rods 6 corresponding end to end is parallel to the horizontal plane, and at this time, the rotation direction of the fan blade 3 tends to be horizontal; when the inclination angle of the connecting rod main rod 602 is continuously decreased, the second rotating rod 5 is continuously moved downwards, and the first rotating rod 4 is continuously moved upwards, so that the rotating direction of the fan blade 3 is changed to the direction of the initial position, and the reversing exhaust fan 32 exhausts air upwards. The above working process is repeated until the motor 1 is turned off after the work is finished.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
