[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0022] This specific implementation provides a ceiling fan, which solves the technical problem in the prior art that the existing ceiling fans generate relatively loud noise when working.

[0023] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0024] Reference Figure 1-Figure 3 The present application document provides a ceiling fan, including a shell 1, a mesh cover 2, a motor 3, a wind wheel 4, and an angle bracket 5. In order to facilitate the installation of the motor 3, the motor 3 is installed on the shell 1, and the shell 1 is used to be fixed on the wall, wherein the shell 1 is configured to be in a trumpet shape, and the trumpet mouth faces the roof, so that dust can be reduced from falling. In order to reduce the noise generated by the ceiling fan during operation, a mesh cover 2 is provided on the shell 1, and the mesh cover 2 is a cover body surrounded by a filamentary structure, so that the air flow can directly pass through the mesh cover 2, and then the motor 3 drives the wind wheel 4 to rotate, wherein the mesh cover 2 is installed on the shell 1 through the angle bracket 5, which facilitates the installation of the mesh cover 2 and reduces noise at the same time. , reducing the load of the motor 3 and increasing the working efficiency; wherein, the wind wheel 4 is installed in the space surrounded by the outer shell 1 and the mesh cover 2 to avoid the situation where the wind wheel 4 falls and is hit. wherein, when the motor 3 drives the wind wheel 4 to rotate, the air can be introduced from the lower end of the mesh cover 2 into the space surrounded by the outer shell 1 and the mesh cover 2, and then transported to the outside through the outer shell 1, which is convenient for air circulation. The present application is to draw air upward, thereby driving indoor circulation. With such a setting, under the condition of the same wind speed, the power of the fan can be reduced, thereby achieving the purpose of energy saving. At the same time, the ceiling fan has a simple structure, is convenient for people to install, is relatively small in size, and can also reduce transportation costs.

[0025] The diameter of the mesh cover 2 is 60-68 cm, which greatly reduces the volume of the ceiling fan and facilitates the transportation of the ceiling fan.

[0026] A further optimization scheme is adopted. In order to reduce the resistance to air circulation, a plurality of guide bodies 6 are arranged on one side of the outer shell 1 close to the mesh cover 2. The guide bodies 6 extend along the axial direction of the outer shell. A guide area 7 is formed between the plurality of guide bodies 6. In this way, the air can diffuse around along the guide area 7, thereby reducing the movement of air toward the roof, increasing the power of diffusion around, and accelerating the air circulation.

[0027] To further optimize the solution, according to the fluid flow conditions, the guide body 6 is set to be arc-shaped, so that the guide area 7 surrounded by the two guide bodies 6 is more convenient for air flow, reduces the resistance of air flow, and allows more air to diffuse to the surroundings.

[0028] To further optimize the solution, in order to facilitate processing, one side of the outer shell 1 is recessed inward and the other side is convex outward to form a flow guide 6. When processing, people directly inject the outer shell 1 through a mold. In this way, the flow guide 6 and the outer shell 1 are set as an integrated structure, which greatly reduces the processing time while ensuring the connection strength between the flow guide 6 and the outer shell 1.

[0029] A further optimized solution is to provide a through hole in the middle of the housing 1 for easy installation of the motor 3 , that is, a through hole for installing the housing 1 is formed when the middle of the trumpet-shaped housing 1 bulges outward, which can save space and prevent the motor 3 from being damaged.

[0030] A further optimized solution also includes a junction box 10 for the convenience of wiring. The junction box 10 is installed at one end of the motor 3 and is electrically connected to the motor 3 to facilitate the connection of the motor 3 to a power source. At the same time, a control device can be installed in the junction box 10 to facilitate the control of the motor 3 to be turned on and off.

[0031] A further optimized solution, in order to facilitate the installation of the motor 3 or the junction box 10, also includes a mounting bar 8, which is installed on the outer shell and is used to support the motor 3, that is, the motor 3 is installed on the mounting bar 8, and the junction box 10 can also be fixed on the mounting bar 8. Specifically, the motor 3 and the junction box 10 are installed on both sides of the mounting bar 8.

[0032] A further optimized solution is to facilitate the installation of the housing 1 on the wall, a hanger 9 for installation on the wall is provided on the side of the housing 1 away from the mesh cover 2, wherein the hanger 9 is provided with a mounting hole, and the fastening screws are fixed to the wall through the mounting hole.

[0033] During specific use, the ceiling fan is installed on the wall through the hanger 9. Since the mesh cover 2 is connected by a filamentary structure, it is convenient for air circulation. At the same time, the guide body 6 on the outer shell 1 facilitates the circulation of gas. The motor 3 drives the air to enter from the lower end of the mesh cover 2 to form a longitudinal airflow. The air is transported outward from the side walls of the outer shell 1 and the mesh cover 2 and along the guide area 7 to achieve the purpose of air circulation, thus forming a transverse airflow. Such an arrangement can help crop growers reduce the adverse effects of humidity on crops in a simple and efficient way. At the same time, the longitudinal and transverse airflows can provide a suitable climate environment for the growth of crops.
