Technical Field
[0001] This application relates to the field of air-drying device technology, and more particularly to a mobile rotary side fan. Background Technology
[0002] A related technology (Announcement No.: CN216232140U) discloses a low-power, low-noise stainless steel fan unit structure for car wash equipment, including two sets of tilting noise-reducing stainless steel fans, four sets of fixed noise-reducing stainless steel fans, and two sets of fixed noise-reducing stainless steel side fans. The two sets of tilting noise-reducing stainless steel fans are mounted on a tilting fan crossbeam, and each end of the tilting fan crossbeam is equipped with a fan unit column for support. A tilting cylinder for driving the tilting fan crossbeam to deflect is installed on the surface of the fan unit column. The four sets of fixed noise-reducing stainless steel fans are mounted on a fixed fan crossbeam, and both ends of the fixed fan crossbeam are fixedly connected to the fan unit columns and distributed on one side of the tilting fan crossbeam. The two sets of fixed noise-reducing stainless steel side fans are respectively mounted on the fan unit columns, and each of the two sets of fixed noise-reducing stainless steel side fans is equipped with a stainless steel air outlet.
[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:
[0004] This car wash equipment features a low-power, low-noise stainless steel fan unit structure. Through a tilting cylinder design, the airflow direction of the two tilting, noise-reducing stainless steel fans can be adjusted, thereby improving the drying effect on the car's roof. However, the airflow direction of the two fixed, noise-reducing stainless steel side fans cannot be adjusted. During the drying of the car's sides, they can only blow directly, leaving blind spots, especially in the front and rear areas.

[0039] Combination Figures 1 to 7As shown, this embodiment of the present disclosure provides a mobile rotary side fan, including a housing 1, a rotating shaft 2, a turntable 3, a support rod 4, a first bracket 5, a fan 6, a second bracket 7, a pin 8, and a cylinder 9. The housing 1 includes an arc-shaped hole on its bottom wall and a rectangular hole on its side wall, the arc-shaped hole and the rectangular hole being used for the support rod 4 and the cylinder 9, respectively. The rotating shaft 2 is rotatably inserted through the bottom wall of the housing 1 along its height direction, and can rotate relative to the bottom wall of the housing 1. The turntable 3 is mounted on the rotating shaft 2 and located inside the housing 1, and can rotate around the axis of the rotating shaft 2 under the support of the rotating shaft 2. The support rod 4 is mounted on the turntable 3 along the height direction of the housing 1 and passes through the arc-shaped hole, and moves along the extension direction of the arc-shaped hole under the drive of the turntable 3. The first bracket 5 is mounted on the support rod 4 and located outside the housing 1, moves under the drive of the support rod 4, and supports the fan 6. A blower 6 is mounted on the first bracket 5 for blowing air to dry the sides of the car. A second bracket 7 is mounted on the outer wall of the housing 1, and a pin 8 is mounted on the turntable 3 along the height of the housing 1. The second bracket 7 and the turntable 3 together support a rotatable cylinder 9. The cylinder 9 is rotatably mounted between the second bracket 7 and the pin 8, and passes through a rectangular hole, allowing it to rotate relative to both the second bracket 7 and the pin 8. Driven by the cylinder 9, the support rod 4 moves along the extension direction of the arc-shaped hole.
[0040] This embodiment of the invention provides a mobile rotary side fan. In use, after connecting the housing 1 to the frame of a car wash machine, it can move back and forth under the drive of the car wash machine frame, thereby drying the entire side of the car. Furthermore, by controlling the operation of the cylinder 9, the extension or retraction of the moving end of the cylinder 9, and with the support of the rotating shaft 2, pushes or pulls the turntable 3 to rotate reciprocally. This, in turn, drives the support rod 4 to move reciprocally along the extension direction of the arc-shaped hole, and then drives the first support to swing reciprocally. Ultimately, this drives the fan 6 to swing reciprocally, continuously adjusting the blowing direction of the fan 6. It can blow directly or obliquely onto the side of the vehicle, thereby reducing blind spots and improving the drying effect.
[0041] Optionally, combined Figure 1 , Figure 2 and Figure 7 As shown, the fan 6 includes a motor, an annular plate, a casing, and an impeller. The motor is mounted on the first bracket 5 to provide driving force for rotational motion. The annular plate is mounted on the motor's flange to support the casing.

The inlet is opposite to the rotating end of the motor to facilitate drawing air into the casing. The impeller is mounted on the rotating end of the motor and located inside the casing. It forces the air drawn in between the blades to rotate, generating centrifugal force to expel the air, thereby increasing the air velocity and pressure.
[0042] In this embodiment of the disclosure, controlling the motor to work can drive the impeller to rotate, thereby drawing outside air into the space between the blades through the air inlet, and then forcing it to rotate, generating centrifugal force and expelling it from the air outlet. The air flow and pressure can then dry the sides of the vehicle.
