[0041] The electric heating component 40 is used to heat the air entering the housing 10, and the air is blown out from the air outlet 12 after being heated and raised in temperature, so that a hot air curtain is blown out. The specific structure of the electric heating component 40 can be designed according to actual needs. For example, in some alternative embodiments, the electric heating component 40 includes a left PTC heating element module 41 and a right PTC heating element module 42. The left PTC heating element module 41 and the right PTC heating element module 42 are respectively arranged on both sides of the middle bracket 31 and are both connected to the middle bracket 31 and the housing 10. The left PTC heating element module 41 and the right PTC heating element module 42 are respectively arranged corresponding to the left wind wheel module 21 and the right wind wheel module 25.

The electric heating assembly 40 is connected to the safety net 17, so that the electric heating assembly 40 is simultaneously connected to the intermediate bracket 31, the mounting plate 13, and the safety net 17, enabling the electric heating assembly 40 to obtain sufficient supporting force and avoiding a single structure providing support for the electric heating assembly 40, making the force more stable. And the intermediate bracket 31 is also simultaneously connected to the mounting plate 13, the electric heating assembly 40, the left motor bracket 22, and the right motor bracket 24, making the front plate 14, the left side plate 15, the side plate, the safety net 17, the intermediate bracket 31, the mounting plate 13, the electric heating assembly 40, the left motor bracket 22, and the right motor bracket closely related to each other and the force between them more stable, making the intermediate bracket 31 not easily deformed and capable of better supporting the electronic component assembly 30, the left motor bracket 22, and the right motor bracket 24.

[0045] The safety net 17 plays a safety protection role to prevent the user's hand from reaching into the air outlet 12 and being scalded by the electric heating assembly 40. The safety net 17 is an integrated safety net 17, which is beneficial to reducing parts and having a simple appearance.

[0046] Please refer to Figure 5 , in some alternative embodiments, a wall hanging plate 18 is detachably provided at the rear side of the housing 10. The wall hanging plate 18 is used to hang the hot air curtain machine on a wall or a bracket and other positions to achieve installation and fixation.

[0047] In some alternative embodiments, the rear side of the housing 10 is provided with a hanging hole 131 and a connecting strip 132 located below the hanging hole 131.

The lower end of the wall hanging plate 18 is formed with an abutting portion 182 that abuts against the lower side of the connecting strip 132, and the abutting portion 182 and the connecting strip 132 are detachably connected through a snap structure or a threaded structure, etc. In this embodiment, during installation, first install the wall hanging plate 18 at a position such as a wall or a bracket, then extend the hanging ear portion 181 into the hanging hole 131 to achieve pre-hanging, and then lock the abutting portion 182 and the connecting strip 132 with screws to complete the installation.

[0048] In some alternative embodiments, a safety net 17 is detachably provided at the air outlet 12. A part of the safety net 17 extends to the rear side of the housing 10, and the connecting strip 132 is provided at the rear side of the safety net 17.

Moreover, the gravity of the fan assembly 20 is dispersed to the mounting plate 13 and also to the safety net 17 through the intermediate bracket 31 and the electric heating assembly 40. Both the mounting plate 13 and the safety net 17 are connected to the wall hanging plate 18, and the mounting plate 13 is also connected to the safety net 17 through the left side plate 15 and the right side plate 16. The gravity of the fan assembly 20 can be evenly dispersed to the mounting plate 13 and the safety net 17. Therefore, when the fan assembly 20 is running, the wall hanging plate 18 can provide stable support for the whole housing 10 to reduce the vibration of the fan assembly 20 and improve the structural stability.
