[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The heating and ventilation fan with convenient internal cleaning provided in the embodiment of the present application is now described.

[0024] Example

[0025] like Figure 1 As shown, a heating and ventilation fan convenient for internal cleaning comprises a guide tube 1 and a fan 2, wherein the guide tube 1 is provided with an air inlet 11, a connection part 12 and an air outlet 13 in sequence, and the fan 2 is arranged in the connection part 12; an air inlet 111 is arranged at the outer end of the air inlet 11, and an air outlet 131 is arranged at the outer end of the air outlet 13; a cleaning valve 14 is arranged in the connection part 12, and the cleaning valve 14 is arranged at the front end of the fan 2. The cleaning valve 14 is a butterfly valve.

[0026] The fan 2 is provided with a motor 21 and an impeller 22, and the impeller 22 is linked with the rotor of the motor 21; the impeller 22 rotates forward to generate warm air; the impeller 22 rotates reversely to drive the airflow inside the guide tube 1 to flow in the reverse direction.

[0027] A radiator 15 is also provided in the connecting portion 12 , and the radiator 15 is provided between the cleaning valve 14 and the fan 2 .

[0028] The connecting portion 12 is in a columnar shape, which can ensure the sealing of the cleaning valve 14 and ensure that the airflow fully contacts the radiator 15 to form warm air, thereby ensuring the heating effect of the heater.

[0029] A dustproof net 16 is detachably installed in the air inlet portion 11 , and a ventilation hole 161 is provided on the dustproof net 16 .

[0030] The air inlet 11 is in a cone shape, and the inner diameter of the air inlet 11 gradually increases from the inside to the outside. Driven by the fan 2, the airflow flowing through the air inlet 11 is gradually squeezed, and the pressure of the airflow gradually increases, which can further ensure the heating effect of the heater.

[0031] A cleaning mechanism 3 is also provided. The cleaning mechanism 3 is provided with a cleaning nozzle 31 and a cleaning valve 32 . The cleaning valve 32 is used to control whether water is supplied to the cleaning nozzle 31 .

[0032] The cleaning mechanism 3 is provided with a supporting seat 33 and a rotating seat 34. The supporting seat 33 is provided with a liquid cavity 331 connected to the water source, and the rotating seat 34 is rotatably arranged in the liquid cavity 331; the cleaning nozzle 31 is linked with the rotating seat 34, and the front end of the cleaning nozzle 31 is inclined, and under the drive of water pressure, the rotating seat 34 can be driven to rotate actively.

[0033] The air outlet 13 is in a cone shape, the inner end of the air outlet 13 is smoothly and sealedly connected to the connecting portion 12 , and the inner diameter of the air outlet 13 gradually increases from the inside to the outside, so that the warm air flow is output smoothly; the fan 2 is close to the air outlet 13 .

[0034] like Figure 2 and Figure 3 As shown, the impeller 22 can be selected with 3 blades or 4 blades according to actual needs.

[0035] Working principle: For the HVAC fan, close the cleaning valve 14, open the cleaning valve 32, and the high-pressure cleaning liquid in the liquid chamber 331 is sprayed toward the dustproof net 16 through the cleaning nozzle 31, which can clean the dust in the air inlet 11 well and clean the inside of the guide tube 1. The cleaning valve 14 can protect the radiator 15 and the fan 2 from the impact of the cleaning liquid; then turn on the fan 2, and the impeller 22 rotates forward to generate warm air. At this time, the humidity in the cleaned air inlet 11 is moderate, which prevents the person's skin from drying out and lacking moisture, and protects the person's health; the impeller 22 reverses, driving the airflow inside the guide tube 1 to flow in the opposite direction, and the hot air flow passes through the guide tube 1 in the opposite direction, and can also take away some of the dust inside the guide tube 1.

[0036] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
