Abstract
Description
Technical Field
[0001] This utility model relates to the field of swirl flow fan technology, specifically a counter-swirl flow fan. Background Technology
[0002] Axial flow fans, with a wide range of applications, are a type of fan where the airflow direction is the same as the axis of the fan blades. Examples include electric fans and air conditioner outdoor unit fans. They are called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure. An axial flow fan is fixed in position and moves air.
[0003] Existing vortex fans typically have their base fixed to a connecting plate, with legs fixed to the bottom of the connecting plate. These legs are then fixed at the mounting point, resulting in a fixed airflow direction for the vortex fan, which cannot be adjusted to the required angle. Utility Model Content

[0006] By adopting the above technical solution, the main body of the blower is supported by the base plate and fixed to the fixed frame with screws. When the operator needs to adjust the blower body up and down, the operator pulls the rotating column outward. The rotating column drives the limiting rod to move, causing the limiting rod to disconnect from the limiting port. Then, the operator rotates the rotating column, which drives the sliding rod and the rotating rod to rotate. The rotating rod drives the gear to rotate, and the rotating gear drives the gear plate to move up and down. The gear plate drives the blower body up and down. When the blower body is moved to the use position, the operator pushes the rotating column to move. The rotating column drives the limiting rod to insert into the limiting port, limiting the gear plate. The other end of the blower body rotates via the rotating seat and the rotating plate.

[0008] By adopting the above technical solution, the base plate supports the main body of the convection fan, and the rotating seat and rotating plate assist the main body of the convection fan in rotating.
[0009] Optionally, the fixing frame is threaded with screws, and the fan body has a connection port, which is threadedly connected to the screws.
[0010] By adopting the above technical solution, screws are connected to the connector, so that the main body of the fan is fixedly connected to the frame.
[0011] Optionally, the lower end of the mobile platform is fixedly connected with multiple sliding wheels.
[0012] By adopting the above technical solution, multiple sliding wheels enable the whole unit to move.
[0013] Optionally, there are multiple limiting ports, and the multiple limiting ports are arranged in a ring with the limiting plate as the center.
[0014] By adopting the above technical solution, multiple limit ports limit the limit rod.
[0015] Optionally, the rotating rod is provided with an anti-slip layer.
[0016] By adopting the above technical solution, slippage during the rotation of the rotating rod can be avoided.
[0017] Optionally, the size of the sliding rod is adapted to the size of the sliding opening.
[0018] By adopting the above technical solution, the discrepancy between the size of the sliding rod and the size of the sliding opening can be avoided, which would cause wobbling.
[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0020] The technical solution of this application uses an adjustment component to drive the main body of the fan to adjust its height, so that the main body of the fan can be used in multiple directions, and the sliding wheels drive the moving platform and the main body of the fan to move.

[0028] In the above technical solution, the main body 8 of the blower is supported by the base plate 6 and fixed to the fixed frame 5 by screws 7. When the operator needs to adjust the blower body 8 up and down, the operator pulls the rotating column 907 outward. The rotating column 907 drives the limiting rod 9010 to move, so that the limiting rod 9010 is disconnected from the limiting port 906. Then the operator rotates the rotating column 907, which drives the sliding rod 909 and the rotating rod 903 to rotate. The rotating rod 903 drives the gear 904 to rotate, and the rotating gear 904 drives the gear plate 905 to move up and down. The gear plate 905 drives the blower body 8 up and down. When the blower body 8 is moved to the use position, the operator pushes the rotating column 907 to move. The rotating column 907 drives the limiting rod 9010 to insert into the limiting port 906, limiting the gear plate 905. The other end of the blower body 8 rotates through the rotating seat 3 and the rotating plate 4.
[0029] In the technical solution of this utility model, such as Figure 3 As shown, a support frame 2 is fixedly connected to the upper end of the mobile platform 1, a rotating seat 3 is fixedly connected to the upper end of the support frame 2, a rotating plate 4 is rotatably connected to the rotating seat 3, a fixed frame 5 is fixedly connected to the rotating plate 4, a base plate 6 is fixedly connected to the upper end of the fixed frame 5, the base plate 6 abuts against the main body 8 of the blower, the fixed frame 5 is fixedly connected to the gear plate 905, the base plate 6 supports the main body 8 of the blower, and the rotating seat 3 and the rotating plate 4 assist the main body 8 of the blower to rotate.

The connection port 11 is threaded onto the screw 7, and the screw 7 is connected to the connection port 11, so that the fan body 8 and the fixed frame 5 are fixedly connected.
[0031] In the technical solution of this utility model, such as Figure 1 As shown, multiple sliding wheels 10 are fixedly connected to the lower end of the mobile platform 1, which enables the entire unit to move.
[0032] In the technical solution of this utility model, such as Figure 2 As shown, there are multiple limit ports 906, which are arranged in a ring around the limit plate 902. The multiple limit ports 906 limit the limit rod 9010.
[0033] In the technical solution of this utility model, such as Figure 4 As shown, the rotating rod 903 is provided with an anti-slip layer to prevent the rotating rod 903 from sliding during rotation.
[0034] In the technical solution of this utility model, such as Figure 1As shown, the dimensions of the sliding rod 909 are matched with the dimensions of the sliding opening 908 to avoid mismatch between the dimensions of the sliding rod 909 and the sliding opening 908, which could cause wobbling.
[0035] In use, the main body 8 of the blower is supported by the base plate 6 and fixed to the fixed frame 5 by screws 7. When the operator needs to adjust the blower body 8 up and down, the operator pulls the rotating column 907 outward. The rotating column 907 drives the limiting rod 9010 to move, so that the limiting rod 9010 is disconnected from the limiting port 906. Then the operator rotates the rotating column 907, which drives the sliding rod 909 and the rotating rod 903 to rotate. The rotating rod 903 drives the gear 904 to rotate, and the rotating gear 904 drives the gear plate 905 to move up and down. The gear plate 905 drives the blower body 8 up and down. When the blower body 8 is moved to the use position, the operator pushes the rotating column 907 to move.
