The supporting seat 400 protrudes out of the outer surface of the supporting frame 100, a plurality of supporting seats 400 are arranged at intervals along the circumference of the supporting frame 100, the supporting seat 400 has a first end 410 and a second end 420 opposite to the first end 410, and the air flow flows from the first end 410 to the second end 420. The heating wire 300 is wound around the support seat 400 to form a plurality of windings 310 and a plurality of extensions 320, thereby increasing a contact area of the heating wire 300 with air, so that the heating wire 300 can sufficiently exchange heat with air. The winding portion 310 abuts against the first end 410 of the support base 400 or the second end 420 of the support base 400, so that the heater wire 300 can be fixed to the support base 400, and the heater wire 300 is prevented from being separated from the support base 400 when the support frame 100 inclines or shakes. The two ends of the extension part 320 are respectively connected with the winding part 310 at the first end 410 and the winding part 310 at the second end 420, heat generated by heating the heating wire 300 is dissipated to the space between the adjacent supporting seats 400, air flow flows through the adjacent supporting seats 400 and takes away the heat generated by the heating wire 300, and because the extension direction of the extension part 320 is the same as or opposite to the flow direction of the air flow, the resistance of the air flow flowing through the extension part 320 is small, the noise of the turbulent flow and the wind is reduced, the loss of the flow speed of the air flow is small, the heat generated by the heating wire 300 can be fully taken away, and therefore the heating efficiency is improved.

In some embodiments, the end of the support seat 400 connected to the support frame 100 is a bottom portion, and the extension portion 320 is used for winding around the adjacent support seat 400, and the end is connected to the winding portion 310 wound around the bottom portion of the first end 410 of the support seat 400, and the other end is connected to the winding portion 310 of the abutting portion of the second end 420 of the adjacent support seat 400. The extending direction of the extending portion 320 for winding the adjacent support seat 400 is not parallel to the flow direction of the air current, and the extending portion 320 of the heater wire 300 connects the winding portions 310 at the bottom of the first end 410 of the support seat 400 and the second end 420 of the support seat 400, thereby maximally reducing the influence on the air current due to the proximity to the support seat 400 and avoiding the increase of the wind resistance.

Referring to fig. 1 to 3, in some embodiments, the supporting base 400 includes two mounting portions 200 spaced apart from each other, one mounting portion 200 is disposed at the first end 410, and the other mounting portion is disposed at the second end 420. The heating wire 300 is wound around the two mounting parts 200, so that the part of the extension part 320 between the two mounting parts 200 is suspended, and the air flow can have a larger contact area with the extension part 320 when flowing through the extension part 320, thereby preventing the extension part 320 from being too close to the support seat 400 and being incapable of fully contacting with the air flow, and further having a better heat exchange effect.

Referring to fig. 1 to 4, a plurality of protrusions 210 are protruded from an outer surface of the mounting part 200, the protrusions 210 are spaced apart from each other in a protruding direction of the mounting part 200 with respect to the supporting stand 100, the heater wire 300 is wound around the protrusions 210, and the winding part 310 abuts against the protrusions 210. The heater wire 300 can be wound in a substantially S-shape along the plurality of protrusions 210 provided on the two mounting parts 200 of the same support 400, and the length of the wound heater wire 300 can be increased in a limited mounting space, thereby increasing heating efficiency.

The extension part 320 of the heating wire 300 is connected to the protrusion 210 of the first end 410 of the support seat 400 and the second end 420 of the support seat 400 and the winding part 310 at the bottom thereof, so that the influence on the air flow can be reduced to the maximum extent due to the proximity to the support seat 400, and the increase of the wind resistance can be avoided.

Referring to fig. 1 to 4, in some embodiments, one end of the mounting part 200 away from the supporting frame 100 is a top part, and both sides of the mounting part 200 are provided with protrusions 210, so that both sides of the mounting part 200 can be wound with the heating wire 300, and the length of the heating wire 300 wound around the protrusions 210 can be increased. The extending part 320 for winding the protruding parts 210 of the two mounting parts 200 in the same supporting seat has one end connected to the winding part 310 wound on one side of one of the mounting parts 200 and located on the protruding part 210 at the top, and the other end connected to the winding part 310 wound on the other side of the other mounting part 200 and located on the protruding part 210 at the top. The extension parts 320 for winding the protruding parts 210 of the two mounting parts 200 in the same support seat are connected to the winding parts 310 on the protruding parts 210 at the top at both sides, so that the included angle between the extension parts 320 and the horizontal plane is small, thereby reducing the influence on the air flow.

Referring to fig. 1 to 4, further, a guide groove 220 is defined between two adjacent protrusions 210, in the same support seat 400, the protrusion 210 of one mount 200 corresponds to the guide groove 220 of the other mount 200, the extension 320 of the heater wire 300 abuts against the facing surfaces of the two mounts 200, the extension 320 extends in the same direction or in the opposite direction to the airflow direction, and the extensions 320 are parallel to each other to reduce the resistance of the heater wire 300 against the airflow.

Referring to fig. 1 to 4, in some embodiments, the end of the protrusion 210 is provided with a mounting groove 211, and the winding part 310 is snapped into the mounting groove 211, so that the relative position of the winding part 310 and the protrusion 210 can be maintained, and thus the heating wire 300 and the protrusion 210 are stably connected to avoid deviation. The plurality of mounting grooves 211 form a groove group 230 along the arrangement direction of the protrusions 210, and the groove group 230 is provided in plurality along the protrusion direction of the protrusions 210. The heating wires 300 are wound around the groove groups 230, and the heating wires 300 wound around the groove groups 230 are parallel to each other with gaps left therebetween, so that the length of the heating wires 300 and the contact area with the air flow can be further increased on the premise of not increasing the wind resistance, thereby improving the heating efficiency.

The air flow can flow through the gaps between the respective heating wires 300 to generate sufficient heat exchange with the heating wires 300, thereby improving the heating efficiency. In addition, each of the heating wires 300 can be heated separately without affecting the state of the remaining heating wires 300, for example, when the heating module 1000 is applied to electric blowing, the power supply applies different voltages to different heating wires 300 corresponding to different temperatures when the air flows out of the second end 420. Preferably, the protrusion 210 is provided with two groove groups 230, and two heating wires 300 are wound around the two groove groups 230, respectively.
