Description

Technical Field

[0001] This utility model belongs to the field of ventilator fan technology, specifically relating to an integrated ventilator fan with a high heat dissipation structure. Background Technology

[0002] The turbine fan is the core component of a ventilator used to drive airflow, and its function directly affects the normal operation of the device and the safety of the patient. The turbine fan generates high-speed airflow and provides the set pressure or flow rate to the patient through precise control.

[0003] Due to the requirements for quiet operation and dust protection, the turbine fan of ventilators typically adopts a fully enclosed shell structure. However, the heat dissipation performance of a fully enclosed shell structure is relatively poor. Under prolonged operation, high temperatures can lead to material aging, performance degradation, and increased noise in the motor components.

[0004] The conventional structure of a ventilator turbine fan consists of a motor assembly connected to a turbine housing assembly at the top. This structure lacks a heat dissipation system; the motor assembly's cooling primarily relies on airflow from the main body of the motor assembly, or on the connection between the top of the motor assembly and the turbine housing, where airflow carries away some of the heat.

[0005] Conventional ventilator turbine fans lack dedicated cooling channels, leading to high temperature buildup after prolonged operation. Therefore, this invention aims to provide an integrated ventilator fan with a superior heat dissipation structure. Utility Model Content

[0006] The purpose of this invention is to provide an integrated ventilator fan with a high heat dissipation structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An integrated ventilator fan with a high heat dissipation structure includes a motor and a turbofan housing assembly. The turbofan housing assembly includes a motor mounting housing and a fan hood housing. The upper end of the motor mounting housing is fixedly connected to the lower end of the fan hood housing. A motor mounting bracket is provided on the inner side of the motor mounting housing. The motor is embedded in the motor mounting bracket for fixation. Several connecting posts are provided between the motor mounting bracket and the motor mounting housing. The space between the motor mounting bracket and the motor mounting housing is an air intake channel.

[0009] The interior of the wind cap shell is an elliptical cavity, the top of the wind cap shell is closed, and the bottom of the wind cap shell is connected to the top of the motor mounting shell; the top of the motor is provided with a fan blade assembly, which is located inside the wind cap shell; an air outlet duct is provided at the wind cap shell.

[0010] Preferably, the fan blade assembly includes a fan blade base and a plurality of arc-shaped fan blades, wherein the plurality of arc-shaped fan blades are evenly distributed in a ring array on the lower surface of the fan blade base.

[0011] Preferably, the wind cap housing has a tapered tube inside, which is wider at the bottom than at the top. The lower edge of the tapered tube is connected to the bottom of the inner side of the wind cap housing, and the upper opening of the tapered tube is aligned with the center of the fan blade assembly.

[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 skilled in the art without creative effort are within the scope of protection of the present utility model. It should be emphasized that since the internal structure of the motor is not a key innovation point in this technical solution, and this type of motor has been widely used in ventilator products and is a conventional product, the external structural schematic diagram and cross-sectional structural schematic diagram of the motor are simplified. This is not because the technical solution is insufficiently disclosed or cannot be implemented. Those skilled in the art can understand the implementation of this technical solution after reading it.

[0023] An integrated ventilator fan with a high heat dissipation structure includes a motor 1 and a turbine housing assembly 2.

[0024] The turbofan housing assembly 2 includes a motor mounting housing 3 and a fan housing 4, with the bottom of the fan housing 4 connected to the top of the motor mounting housing 3. Inside the motor mounting housing 3, a motor mounting bracket 5 is provided, and several connecting posts 6 are provided between the motor mounting bracket 5 and the motor mounting housing 3. The motor mounting bracket 5 is fixed by the connecting posts 6. The motor 1 is embedded in the motor mounting bracket 5 for fixation. An air inlet channel 7 is located between the motor mounting bracket 5 and the motor mounting housing 3, through which external air is introduced into the fan housing 4. The top of the fan housing 4 is closed, and an air outlet duct 8 is provided at the fan housing 4, through which the airflow entering the fan housing 4 is discharged.

[0025] The interior of the wind turbine housing 4 is an elliptical cavity. The fan blade assembly 9, located on top of the motor, is situated inside the wind turbine housing 4. The fan blade assembly 9 includes a fan blade base 10 and several arc-shaped fan blades 11. These arc-shaped fan blades 11 are evenly distributed in a circular array on the lower surface of the fan blade base 10, with the arc-shaped fan blades 11 facing the air inlet channel 7. To enhance the airflow order inside the turbine housing assembly 2, a tapered tube 12 is provided inside the wind turbine housing 4. The tapered tube 12 is wider at the bottom than the top, with its lower edge connected to the inner bottom of the wind turbine housing 4, and its upper opening aligned with the center of the fan blade assembly 9. The tapered tube 12 concentrates and directs the airflow introduced from the air inlet channel 7 towards the center of the fan blade assembly 9.

[0026] During operation, motor 1 drives fan blade assembly 9 to rotate. External air is introduced into the fan cap housing 4 through air inlet channel 7. Further, fan blade assembly 9 exhausts the air inside the fan cap housing 4 through air outlet duct 8. During airflow, the heat accumulated in motor 1 is carried away by the flowing air, thus cooling motor 1.
