[0065] See also Figure 2 , Figure 21 is a schematic diagram of the structure of a car washing machine air drying device 2 according to an embodiment of the present invention. The car washing machine air drying device 2 according to this embodiment comprises a left fan 21 and a right fan 22 for drying the surface moisture of a vehicle, which are arranged at both ends of a car washing machine cross beam 11, and a fan angle adjustment mechanism 26 respectively connected to the left fan 21 and the right fan 22. An air outlet 25 is hingedly connected to the air outlet 24 of the left fan 21 and the right fan 22. The fan angle adjustment mechanism 26 is connected to the air outlet 25. The air outlet 25 can swing relative to the central axis of the end of the air outlet 24 under the drive of the fan angle adjustment mechanism 26. The left fan 21 and the right fan 22 respectively comprise a fan housing 23 and an impeller and a driving motor installed in the fan housing 23. The driving motor is connected to the impeller. The fan housing 23 is installed on the car washing machine cross beam 11. A cylindrical air outlet 24 is arranged below the fan housing 23.

[0066] Among them, the fan angle adjustment mechanism 26 includes: a swing mechanism 261, which is installed and fixed on the car washing machine beam 11; a plurality of over-the-line guide mechanisms 262, which are respectively installed and fixed on the car washing machine beam 11 corresponding to the left fan 21 and the right fan 22. In this embodiment, there are a total of 4 over-the-line guide mechanisms 262, which are symmetrically arranged on both sides of the swing mechanism 261 and at positions on both sides close to the left fan 21 and the right fan 22; and a flexible long connecting member 263, one end of which is fixedly connected to the air outlet 25 of the left fan 21, and the other end passes through the over-the-line guide mechanism 262 and is connected to the air outlet 25 of the right fan 22. The flexible long connecting member 263 is connected to the swing mechanism 261 and is tensioned between the over-the-line guide mechanism 262 and the air outlet 25. The flexible long connecting member 263 263 may be a connecting rope, which may be a rope such as a steel wire rope, a composite rope, a long fiber metal composite rope or a nylon rope, which has the required flexibility and rigidity, preferably a nylon rope, one end of which is connected to the air outlet 25 of the left fan 21, and the other end of which passes through the wire guide mechanism 262 and the swing mechanism 261 in sequence and is tensioned before being fixedly connected to the air outlet 25 of the right fan 22, thereby achieving that the left fan 21 and the right fan 22 can swing synchronously through the tensioned nylon rope under the drive of the swing mechanism 261; wherein, the air outlets 25 of the left fan 21 and the right fan 22 swing synchronously toward each other relative to the axes of the corresponding air outlets 24 of the left fan 21 and the right fan 22 respectively through the tensioned flexible long connecting member 263 under the drive of the swing mechanism 261.

[0067] See also Figure 3 , Figure 32 is a schematic diagram of the structure of a swing mechanism 261 according to an embodiment of the present invention. The swing mechanism 261 according to this embodiment includes: a fixed frame 2611, mounted on the cross beam 11 of the car washing machine; a slide rail 2612, mounted on the fixed frame 2611; a driving mechanism 2613, mounted on the fixed frame 2611, which can be preferably a motor; an eccentric wheel 2614, connected to the driving mechanism 2613, and in this embodiment, the eccentric wheel 2614 is mounted on the motor shaft; and a wire plate 2615, which is abutted against the eccentric wheel 2614 and slidably mounted on the slide rail 2612, and the flexible long connecting member 263 is fixedly connected to the wire plate 2615; wherein the driving mechanism 2613 drives the eccentric wheel 2614 to rotate, drives the wire plate 2615 to move up and down along the slide rail 2612, and drives the flexible long connecting member 263 to pull the air outlet nozzles 25 of the left fan 21 and the right fan 22 to swing back and forth synchronously. Among them, the eccentricity of the eccentric wheel 2614 is positively correlated with the swing angle of the air outlet 25. The eccentricity of the eccentric wheel 2614 is preferably 80 mm, and the stroke of the slide rail 2612 is preferably 100 mm. The eccentricity of the eccentric wheel 2614 is close to the pulling distance of the nylon rope. When the eccentricity is 80 mm, the corresponding swing angle of the air outlet 25 is 25°. The maximum swing angle corresponds to the eccentricity. The larger the eccentricity, the larger the maximum swing angle. The swing angle of the air outlet 25 is preferably 20°-30°. Usually, the best swing angle for a car below 1.5m is 20°, and the best swing angle for a car with a height of 1.7m is 30°. If the maximum swing angle cannot be adjusted automatically, the preferred swing angle is 25°.

[0068] See also Figure 4 , Figure 4 : is a schematic diagram of the structure of the wire-passing guide mechanism 262 of an embodiment of the present invention. The wire-passing guide mechanism 262 can be a lifting ring, a buckle or other structure that can allow the flexible long connecting member 263 to pass smoothly and can play a guiding role. In this embodiment, the wire-passing guide mechanism 262 includes: a fixed shaft 2621, which is installed on the cross beam 11 of the car washing machine; a bearing pulley 2622, which is installed on the fixed shaft 2621, and the outer surface of the bearing pulley 2622 is provided with a groove 2623 along its circumferential direction to accommodate the flexible long connecting member 263 to prevent it from falling out. The wire-passing guide mechanism 262 may also include a baffle 2624 to further prevent the nylon rope from falling off, and the groove 2623 corresponding to the bearing pulley 2622 is installed on the fixed shaft 2621, and the flexible long connecting member 263 passes between the baffle 2624 and the groove 2623 to prevent it from falling off.

[0069] See also Figure 5 , Figure 5Schematic diagram of the connection relationship of the air outlet nozzle 25 of an embodiment of the present invention. In this embodiment, the end of the air outlet 24 is hinged to the air outlet nozzle 25 through a rotating shaft, the rotating shaft is fixed to the end of the air outlet 24, and the air outlet nozzle 25 can rotate around the rotating shaft. The air outlet nozzle 25 is a cylindrical structure adapted to the air outlet 24. A limiting boss 251 is provided on the outer side of the air outlet nozzle 25. When the angle between the air outlet nozzle 25 and the air outlet 24 is 0°, the limiting boss 251 abuts against the outer end of the air outlet 24, so the air outlet nozzle 25 can only swing inward in one direction.

[0070] When working, the left fan 21 and the right fan 22 will apply tension to both ends of the flexible long connection member 263 during the drying operation, and the driving mechanism 2613 drives the eccentric wheel 2614 to rotate, thereby driving the wire plate 2615 to move up and down along the slide rail 2612. The up and down movement of the wire plate 2615 drives the flexible long connection member 263 to reciprocate along the bearing pulley 2622 of the wire guide mechanism 262, thereby realizing the synchronous reciprocating swing of the air outlet nozzles 25 of the left fan 21 and the right fan 22 relative to the central axis of the end of the air outlet 24.

[0071] See also Figure 6 , Figure 6 FIG. 2 is a structural diagram of a car washing machine air drying device 2 according to another embodiment of the present invention. Figure 2 The main difference between the illustrated embodiment is that the car washer air drying device 2 of the present embodiment further includes a middle fan 27. In the absence of the fan angle adjustment mechanism 26, the air outlets 24 of the left fan 21 and the right fan 22 can only blow to the door position of the vehicle 3, but after the fan angle adjustment mechanism 26 is added, since the air outlet 25 can swing, the drying range can be expanded to part of the roof, so that the left fan 21 and the right fan 22 cooperate with the middle fan 27 to achieve drying without dead angles.

[0072] The present invention can improve the drying effect of the fans without increasing the number of fans, and the control method is simple. It only needs a unidirectional motor to drive the eccentric wheel to drive the air outlet nozzles on the left and right fan outlets to swing, so as to expand the drying range. In conjunction with the middle fan, drying can be achieved without dead angles, effectively improving the drying efficiency.

[0073] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
