[0033] like Figures 1 to 5 As shown, a heating element installation structure includes a base 1;

[0034] A heating element 2, which is arranged on the base 1, and the heating element 2 is used for heating after being powered on;

[0035] Fans 3, a plurality of fans 3 are disposed on the base 1, and the fans 3 face the heating element 2, so that the air from the fans 3 passes through the heating element 2 and blows out warm air to the outside;

[0036] The air guiding channel 13 is disposed on the base 1 , and the air guiding channel 13 is used to guide the air output of the fan 3 to the heating element 2 .

[0037] The present solution provides a novel installation structure for a heating element, which integrates a traditional PTC heating element 2 installation bracket and a fan installation base into an integrated design, that is, the heating element 2 and the fan 3 are installed on the same base 1. The overall structure is relatively simpler, and an air guide channel 13 is also provided on the base 1 corresponding to the fan 3, so that the air outlet is smoother and more concentrated, and the noise when the structure is used can be effectively reduced.

[0038] Furthermore, the base 1 is provided with a mounting groove 11, and the heating element 2 is arranged in the mounting groove 11;

[0039] The base 1 is also provided with a plurality of air inlet channels 12, each of which is interconnected with the mounting slot 11, and the fan 3 is arranged at the rear side of the air inlet channel 12, so that the air discharged by the fan 3 is blown toward the air inlet channel 12 and the heating element 2 in sequence;

[0040] The air guide channel 13 is disposed between the air inlet channel 12 and the mounting groove 11 , and the inner diameter of the air guide channel 13 gradually decreases from an end close to the fan 3 to an end far from the fan 3 .

[0041] The interior of the base 1 is a hollow structure, and the mounting groove 11 is approximately rectangular in shape. The heating element 2 is located in the mounting groove 11. The rear side of the mounting groove 11 is provided with an air guide channel 13 and an air inlet channel 12 in sequence. Two fans 3 are installed on the base 1 at intervals. Correspondingly, two air inlet channels 12 are arranged on the base 1 at intervals, and the air outlet of the fan 3 faces the air inlet channel 12. The air outlet of the fan 3 can be blown toward the heating element 2 through the air inlet channel 12 and the air guide channel 13, and then the warm air is blown out to the outside. From the end close to the fan 3 to the end close to the heating element 2, the inner diameter of the air guide channel 13 of this embodiment gradually decreases, that is, the air outlet of the fan 3 is more concentrated, and the warm air outlet effect is better.

[0042] Furthermore, along the length direction of the base 1, the bottom end of the air inlet channel 12 extends obliquely from top to bottom to form two air guiding curved surfaces 131, and the air guiding channel 13 is formed between the air guiding curved surfaces 131. In this embodiment, at the lower end of each air inlet channel 12, only two sides form the air guiding curved surfaces 131 (specifically, the sides in the long side direction of the base 1 / mounting slot 11), the upper end of the air guiding curved surface 131 is connected to the air inlet channel 12, and the lower end is connected to the mounting slot 11, and the other two sides of the air inlet channel 12 are directly connected to the mounting slot 11. The lower end is not provided with the air guiding curved surface 131, and the heating element 2 is not provided at the end of the mounting slot 11, that is, there is still a certain distance between the heating element 2 and the air inlet channel 12 and the air guiding channel 13. In this way, the guiding curved surface not only plays a role in guiding the air, but also can gather the air outlet of the fan 3 in the same mounting slot 11 for uniform heating.

[0043] Furthermore, the heating element 2 is a PTC heating element 2; the lower surface of the base 1 is recessed upward to form the mounting groove 11, and openings 111 are provided on both sides of the mounting groove 11. The two ends of the heating element 2 extend to the outside of the mounting groove 11 through the openings 111, and the base 1 is provided with a removable end cover of the heating element 2, and the two ends of the heating element 2 are respectively clamped on the two end covers of the heating element 2.

[0044] In order to better fix the heating element 2 on the base 1, an end cover of the heating element 2 is provided on the base 1, and the mounting groove 11 is recessed upward so that the base 1 protrudes upward in an approximately cylindrical shape. Both ends of the heating element 2 extend from the opening 111 and are fixed by the end cover of the heating element 2. The end cover of the heating element 2 is fixed to the upper surface of the bottom cover by bolts, which is convenient for disassembly and replacement of parts.

[0045] Furthermore, a temperature limiter 4 is included for limiting the heating element 2 from exceeding a preset temperature. The temperature limiter 4 is arranged on the base 1 and is electrically connected to the heating element 2. The temperature limiter 4 can ensure that the heating element 2 will not overheat and prevent the hot air with too high a temperature from being blown outward, which is safer.

[0046] Furthermore, the base 1 is provided with a first fixing groove 14 and a mounting cover 15, the temperature limiter 4 is arranged in the first fixing groove 14, and the mounting cover 15 is arranged above the first fixing groove 14 to clamp the temperature limiter 4 in the first fixing groove 14;

[0047] The base 1 is also provided with a limiting portion 16 for preventing the temperature limiter 4 from shifting. The limiting portion 16 is arranged at the rear side of the temperature limiter 4 , and one end of the mounting cover 15 is detachably connected to the top end of the limiting portion 16 .

[0048] The temperature limiter 4 is installed in the first fixing groove 14. The first fixing groove 14 has a plurality of plug-in positions. The extended part of the temperature limiter 4 itself can be inserted in the above-mentioned plug-in positions. A mounting cover 15 is provided above the temperature limiter 4 to fix it. One end of the mounting cover 15 abuts against the base 1, and the other end is fixed to the top of the limiting portion 16 by screws. The rear side of the temperature limiter 4 is blocked by the limiting portion 16 to prevent the temperature limiter 4 from falling out from the rear and is stably fixed in the first fixing groove 14.

[0049] Furthermore, it also includes a fuse 5 for generating heat and melting when the current exceeds a preset threshold value. The fuse 5 is electrically connected to the heating element 2.

A fastener 171 is detachably connected to the base 1, and the lower end of the fastener 171 is embedded in the second fixing groove 17 and abuts against the outer wall of the fuse 5.

[0050] The base 1 in the present installation structure is also provided with an installation position for the fuse 5. The fuse 5 is a safety device for protecting the heater circuit. It can automatically cut off the power supply when the current is too large to prevent fire and other safety problems caused by circuit overload. The base 1 is provided with a corresponding second fixing groove 17, which is located on one side of the outer wall of the air inlet channel 12. The fuse 5 is partially stuck in the second fixing groove 17. The base 1 is fixed with a fastener 171 which is removed and fixed by screws. The fastener 171 clamps the fuse 5 in the second fixing groove 17 to prevent the fuse 5 from shifting.
