Description

Technical Field

[0001] This utility model relates to the field of cooling fans, specifically a cooling clothing fan, which is particularly used in cooling clothing. Background Technology

[0002] Cooling clothing fans, which are installed on clothing to blow air and cool the human body, are small and lightweight. They are mostly powered by portable power sources (such as power banks or batteries) and can achieve the purpose of blowing air and cooling the human body.

[0003] It mainly consists of a main body, motor, fan, DC mount, and grille. The DC mount is usually mounted on the central hub of the grille, while higher-end cooling fans will have a semiconductor cooling fin installed on the central hub at the air outlet to cool the blown air. The ribs on common fan grilles are mostly set parallel to the air outlet axis. When the fan rotates, the ribs of the grille obstruct the airflow, affecting the airflow speed and volume. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling clothing fan to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cooling clothing fan, comprising:

[0006] The main body has fan blades mounted inside it in a rotating manner;

[0007] Ribs are set on one side of the air outlet of the main body and are set at an angle;

[0008] The preferred inclination angle of the ribs is 0-30 degrees.

[0009] Preferably, the inclination angle of the rib is 20-30 degrees.

[0010] Preferably, it also includes a DC holder, which is fixedly mounted on the side of the main body.

[0011] Preferably, a wire is also fixedly installed at the air outlet of the main body, which is used to house wires for connecting the DC base and the motor of the fan blade.

[0012] Preferably, a buckle is also fixedly installed on the side of the main body, and the buckle is used to install external wires.

[0013] Preferably, an LED light is fixedly installed at the central hub of the fan blade.

[0014] Preferably, a semiconductor cooling chip is fixedly installed at the central hub of the fan blade.

[0015] Preferably, a switch is installed at the central hub of the fan blade.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention sets the ribs of the mesh cover to be inclined, with an inclination angle of 0-30 degrees. As the angle increases, the air volume increases when the fan blades rotate. The air volume is at its maximum when the inclination angle is 30 degrees. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 As shown, this embodiment discloses a cooling clothing fan, including:

[0024] Main body 1 is a circular structure, and a motor and fan blades are fixedly installed inside it. The output end of the motor is fixedly connected to the fan blades and is used to drive the fan blades to rotate.

[0025] Rib 2 is located on one side of the air outlet of the main body 1, such as... Figure 1-3 As shown, multiple ribs 2 are provided and distributed in a ring shape to form a circular mesh structure (i.e., a mesh cover), which is fixed to the air outlet of the main body 1 with bolts. The intersection of the ribs 2 serves as the central hub for mounting the motor. The ribs 2 are inclined on the main body 1, with the inclination direction being the same as the rotation direction of the fan blades. The inclination angle is preferably 0-30 degrees, specifically 20-30 degrees.

[0026] One of the ribs 2 is relatively thicker and has a slot for placement. This rib serves as a placement line 4 for placing the wires connecting the motor and the DC socket.

[0028] The experimental data above shows that as the angle of the rib 2 gradually increases from 0 degrees to 30 degrees, the airflow gradually increases, reaching its maximum at an angle of 30 degrees. Beyond 30 degrees, the airflow gradually decreases. The fan in this application, used on cooling or heat-dissipating clothing, blows directly onto the body for heat dissipation. The maximum angle is 30 degrees. When the angle is too large, the airflow angle is also relatively large, causing it to blow away from the body.

[0029] It also includes a DC connector 5, which is fixedly installed on the side of the main body 1. The DC connector is an interface for connecting a DC fan, such as the DC044 model available on the market. Depending on the wind pressure, other models of DC connectors can also be selected. The DC connector is located on the side, which reduces the overall height of the central hub compared to existing DC connectors located at the center hub. Furthermore, common DC connectors are mostly rectangular, with an overall width and length slightly larger than the central hub. When the DC connector 5 is installed with the central hub, it blocks the air outlet of the main body 1, affecting airflow. This application places the DC connector on the side, reducing the obstruction of the air outlet by the DC connector 5, resulting in smoother airflow and a larger airflow path.

[0030] In a further embodiment, an LED light 3 is fixedly mounted on the central hub. The wiring of the LED light 3 is connected to a DC socket to provide power to the LED light 3. The LED light can provide illumination at night, and when used at night, the light emitted by the LED light 3 also has a certain warning function to remind pedestrians or vehicles passing by.

[0031] In another embodiment, a semiconductor cooling chip (existing technology, directly purchased from the market) is fixedly installed at the central hub. When the blown air passes through the semiconductor cooling chip, it will cool the air and have a better cooling effect on the human body.

[0032] In a further embodiment, a switch 6 (a one-touch switch) is installed at the center hub. The switch 6 is connected in series in the circuit between the motor and the DC socket to control the operation of the motor.

[0033] A buckle 7 is also fixedly installed on the outside of the main body 1, such as... Figure 3 As shown, the clip 7 has an L-shaped structure and is used to clip external wires. Compared to the current cooling fan where the clip 7 is set on the mesh plate formed by the ribs 2 (the current DC socket is installed on the center hub, and its wiring must pass through the ribs, so the clip 7 needs to be set on the ribs 2), setting the clip 7 on the side to match the position of the DC socket 5 makes the wiring more reasonable, reduces the overall height, and is more convenient to use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
