[0002] A hot air curtain is a powerful airflow generated by a high-speed motor driving a cross-flow or centrifugal fan, forming an invisible curtain. Therefore, it is also called an air curtain machine, air barrier, or air door. It serves to block the alternation of hot and cold air and to block dust. An electric hot air curtain is an air curtain machine that uses electric heating. Hot air curtains are high-power electrical devices that convert electrical energy into heat energy. Due to their large heat release and safety, they have a wide range of applications and are highly favored by the market.

[0003] Existing hot air curtains do not have an air filtration structure, and dust particles will enter the hot air curtain as it operates. The longer it is used, the more dust particles will affect the stability of the fan and the service life of the heater. In addition, most electric hot air curtains only heat the air through electric heating elements, which consumes a lot of energy and is not conducive to the environmentally friendly use of hot air curtains. Utility Model Content

This solves the problem mentioned in the background art that the existing hot air curtain does not have an air filtration structure, and dust particles will enter the hot air curtain as it is working. The longer it is used, the more the dust particles will affect the stability of the fan and the service life of the heater. In addition, most electric hot air curtains only heat the air through electric heating elements, which consumes a lot of energy and is not conducive to the environmentally friendly use of hot air curtains.

[0013] Compared with the prior art, this utility model provides an environmentally friendly heat curtain with the following advantages:

[0014] 1. This utility model uses a coarse filter to intercept large particles of dust, hair, etc. in the air; the filter plate can filter out most of the fine particulate matter, and the activated carbon plate can adsorb odors and harmful gases, such as formaldehyde and benzene, improving air quality, preventing dust particles from affecting the air curtain, and extending the service life of the air curtain. Furthermore, the filter frame is quickly installed on one side of the air curtain machine housing via a limiting frame and connecting plate, making the connection simple and facilitating disassembly of the filter frame and internal maintenance of the air curtain machine housing. Both the filter plate and the activated carbon plate can be disassembled independently, facilitating component maintenance.

[0015] 2. This utility model introduces water into and drains water into the heater's internal pipes through an inlet pipe and an outlet pipe, respectively. The input hot water raises the surface temperature of the heater, thereby heating the airflow passing through the gaps inside the heater. The hot air is discharged from the outlet, creating a hot air curtain. There are multiple sources of hot water, which can be directly supplied to the factory for production, thus saving electricity and reducing dependence on traditional energy sources. When the heat is insufficient, the air is heated by an electric heating element, improving energy efficiency.
