The end of the connecting groove 4 away from the air inlet pipe 2 is provided. Sealing gaskets 6 are installed on the side of the two heating boxes 1 that are close to each other. When the two heating boxes 1 are fixed, the two sealing gaskets 6 are tightly pressed together, and the two connecting grooves 4 are connected. Heating baffles 5 are installed equidistantly inside the heating box 1. Two adjacent heating baffles 5 are fixedly connected to the inner top wall and inner bottom wall of the heating box 1, respectively, so that the multiple heating baffles 5 form an S-shaped flow channel inside the heating box 1. A snap-fit ​​assembly 7 is installed between the air intake pipe 2 and the exhaust pipe 3. A tensioning assembly 8 is installed between them. Sound-absorbing cotton is installed on the inner wall of the heating box 1. A heating coil is installed inside the heating baffle 5. The heating baffles 5 arranged in an alternating manner inside the heating box 1 divide the interior of the heating box 1 into an S-shape, extending the flow length and improving the heating effect. During the flow, the generated sound waves are absorbed, scattered, or interfered by the multiple heating baffles 5, thereby reducing the sound energy and achieving the purpose of noise reduction. At the same time, the sound-absorbing cotton installed on the inner wall of the heating box 1 improves the noise reduction effect.

[0025] The snap-fit ​​assembly 7 includes a first fixed box 702 fixedly installed at the end of the upper heating box 1 away from the air intake pipe 2. A connecting rod 704 is movably installed inside the first fixed box 702. One end of the connecting rod 704 extends to the outside of the first fixed box 702. An mounting plate 705 is installed at one end of the connecting rod 704. A locking rod 706 is installed on the mounting plate 705. The locking rod 706 is snapped into the inside of the locking groove 701. The locking groove 701 is symmetrically opened at the end of the lower heating box 1 away from the exhaust pipe 3.

[0026] The tensioning assembly 8 includes two second fixed boxes 801 respectively installed on the side of the intake pipe 2 and the exhaust pipe 3 close to each other. A second movable plate 802 is movably installed inside the second fixed box 801. A fixed rod 803 is installed on the side of the two second movable plates 802 close to each other. A magnetic block 804 is installed at the end of the fixed rod 803. A second spring 805 is symmetrically installed on the side of the second movable plate 802 away from the fixed rod 803. One end of the second spring 805 is fixedly connected to the inner wall of the end of the second fixed box 801. The two magnetic blocks 804 have opposite magnetic properties. The two heating boxes 1 are connected by a locking rod 706 and a locking slot 701, which is convenient for disassembly and assembly and convenient for maintenance of the inside of the heating box 1. At the same time, the magnetic blocks 804 on the side of the intake pipe 2 and the exhaust pipe 3 close to each other attract each other, improving the installation stability. The spring force of the second spring 805 presses the two heating boxes 1 together, improving the air circulation and sealing.

[0027] Working principle: During operation, when the two heating boxes 1 are brought into contact, the two sealing gaskets 6 are pressed tightly together, and the two connecting grooves 4 are connected. A fan is installed at one end of the air inlet pipe 2, and one end of the exhaust pipe 3 is connected to the air conditioner outlet. During installation, the mounting plate 705 is pulled outward. After the two heating boxes 1 are assembled, the clamping rod 706 is inserted into the clamping groove 701 to clamp and fix the two heating boxes 1. At the same time, two fixing rods 803 on the side of the air inlet pipe 2 and the exhaust pipe 3 that are close to each other are equipped with magnetic blocks 804 with opposite magnetic properties. After the two magnetic blocks 804 attract each other, the two heating boxes 1 are further fixed. At the same time, the second movable plate 802 moves to stretch the second spring 805. Under the elastic force of the second spring 805, the installation tightness of the two heating boxes 1 is improved.

[0028] Turn on the fan to draw outside air into the upper heating chamber 1. The staggered heating baffles 5 inside the heating chamber 1 divide the inner cavity of the heating chamber 1 into an S-shape. The heating baffles 5 heat the air, extending the airflow heating length and improving the heating effect. At the same time, when the air flows inside the heating chamber 1, the sound waves are absorbed, scattered, or interfered by the heating baffles 5, thereby reducing the sound energy and achieving the purpose of noise reduction. In addition, sound-absorbing cotton is installed on the inner wall of the heating chamber 1 to improve the noise reduction effect.
