[0041] The specific structure of a heating device provided by an embodiment of the utility model and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0042] In this embodiment, the first direction is direction a, the second direction is direction b, and the third direction is direction c.

[0043] Please refer to Figure 1-Figure 6 A heating device provided by an embodiment of the utility model includes a mounting frame 100 , a corrugated heating belt 310 and a plurality of limiting plates 200 .

[0044] The mounting frame 100 includes two first plate bodies 110 and a plurality of mounting plates, wherein the two first plate bodies 110 are arranged at intervals along a first direction, and the plurality of mounting plates are arranged at intervals along a second direction, and both ends of the mounting plates are respectively connected to the two first plate bodies 110, and both ends of at least one mounting plate among the plurality of mounting plates are respectively detachably connected to the two first plate bodies 110. In the present embodiment, both ends of each mounting plate are respectively detachably connected to the two first plate bodies 110.

[0045] The mounting plate is located between the two first plates 110 , and any two adjacent mounting plates and the two first plates 110 form an accommodating cavity 131 .

[0046] Optionally, in order to ensure the assembly stability of the corrugated heating belt 310 located in the accommodating cavity 131, the crests and troughs of the corrugated heating belt 310 may respectively abut against two adjacently arranged mounting plates.

[0047] It should be noted that, in this embodiment, a plurality can be understood as a number of two or more than two.

[0048] Each accommodating cavity 131 is provided with a limiting plate 200, and both ends of the limiting plate 200 are detachably connected to the two first plate bodies 110 respectively. The limiting plate 200 is used to fix the corrugated heating belt 310. It can be understood that the limiting plate 200 can prevent the corrugated heating belt 310 located in the accommodating cavity 131 from shifting during the heating process.

[0049] Each accommodating cavity 131 has a corrugated heating belt 310, and the corrugation density of the corrugated heating belt 310 is 2-5 mm. It can be understood that the corrugation density can be understood as the distance between any two adjacent wave peaks on the corrugated heating belt 310. It can be understood that for the corrugated heating belt 310, increasing the corrugation density can improve the heating efficiency of the corrugated heating belt 310.

[0050] Optionally, in some embodiments, the corrugation density may be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm.

[0051] Of course, in the accommodating cavity 131, the corrugation density cannot be too small or too large, that is, the spacing between two adjacent wave peaks does not have to be less than 2 mm, so as to ensure that there is enough gap between adjacent wave peaks for external air to pass through, so as to ensure the heat dissipation efficiency with the external air. In this embodiment, the corrugation density is within the range of 2 to 5 mm, which can ensure that the heating device 1 has a higher thermal efficiency.

[0052] Optionally, the thickness of the corrugated heating belt 310 is in the range of 0.08 to 0.3 mm. It is understandable that when the thickness of the corrugated heating belt 310 is relatively small, the heat dissipation efficiency of the corrugated heating belt can be ensured, thereby ensuring the thermal efficiency during the heating process.

[0053] Optionally, in the present embodiment, the thickness of the corrugated heating belt 310 is 0.1 mm. Of course, in other optional embodiments, the thickness of the corrugated heating belt 310 may also be 0.08 mm, 0.09 mm, 0.11 mm, 0.12 mm, 0.13 mm, ... or 0.3 mm.

[0054] Optionally, the width of the corrugated heating belt 310 is in the range of 2 to 15 mm. The width of the corrugated heating belt 310 can be understood as the size of the corrugated heating belt 310 in the third direction. In this embodiment, the width of the corrugated heating belt 310 is 9 mm. Of course, in other optional embodiments, the width of the corrugated heating belt 310 can also be 2 mm, 3, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or 15 mm.

[0055] When the thickness of the corrugated heating belt 310 is 0.1 mm, the width is 9 mm, and the corrugation density is 2 mm, 3 mm, 4 mm, or 5 mm, please refer to the following Table 1 for the air outlet temperature data of the heating device.

[0056] Table 1

[0057] Thickness(mm) 0.1 0.1 0.1 0.1 Width(mm) 9 9 9 9 Corrugation density (mm / wave) 2 3 4 5 Air outlet temperature (℃) 50.3 54.4 56.5 53.6

[0058] When the width of the corrugated heating belt 310 is 9 mm, the corrugation density is 4 mm, and the thickness is 0.06 mm, 0.08 mm, 0.1 mm, 0.15 mm, or 0.2 mm, please refer to Table 2 below for the air outlet temperature of the heating device.

[0059] Table 2

[0060] Width(mm) 9 9 9 9 9 Corrugation density (mm / wave) 4 4 4 4 4 Thickness(mm) 0.06 0.08 0.1 0.15 0.2 Air outlet temperature (℃) 49.3 51.2 56.5 54.1 53.2

[0061] When the thickness of the corrugated heating belt 310 is 0.1 mm, the corrugation density is 4 mm, and the width is 3 mm, 7 mm, 9 mm, 13 mm, or 15 mm, please refer to Table 3 below for the air outlet temperature of the heating device.

[0062] Table 3

[0063] Thickness(mm) 0.1 0.1 0.1 0.1 0.1 Corrugation density (mm / wave) 4 4 4 4 4 Width(mm) 3 7 9 13 15 Air outlet temperature (℃) 48.3 52.3 56.5 56.2 55.5

[0064] It can be seen from the above table that when the thickness of the corrugated heating belt is 0.1, the corrugation density is 4mm, and the width is 9mm, the air outlet temperature is better.

[0065] Optionally, the thickness of the corrugated heating belt 310 is in the range of 0.06 to 0.18 mm. It is understandable that when the thickness of the corrugated heating belt 310 is smaller, the heat dissipation efficiency of the corrugated heating belt can be ensured, thereby ensuring the thermal efficiency during the heating process.

[0066] Optionally, in the present embodiment, the thickness of the corrugated heating belt 310 is 0.1 mm. Of course, in other optional embodiments, the thickness of the corrugated heating belt 310 may also be 0.08 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.15... or 0.18 mm.

[0067] It can be understood that, limited by the size of the mounting frame 100, in some other embodiments, the width of the corrugated heating belt 310 is in the range of 3 to 4.8 mm. The width of the corrugated heating belt 310 can be understood as the size of the corrugated heating belt 310 in the third direction. In this embodiment, the width of the corrugated heating belt 310 is 4.8 mm. Of course, in other optional embodiments, the width of the corrugated heating belt 310 can also be 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm, 4 mm, 4.2 mm, 4.4 mm, 4.5 mm or 4.6 mm.

[0068] The first direction and the second direction form an angle. Specifically, in this embodiment, the first direction and the second direction are perpendicular to each other.

[0069] It should be noted that the above-mentioned mounting plate, mounting frame 100 and limiting plate 200 are all made of insulating materials.

[0070] It can be understood that in this embodiment, the corrugated heating belt 310 is located in the accommodating cavity 131. During the heating process, the corrugated heating belt 310 can directly exchange heat with the external air without having to transfer heat through other additional structures, thereby reducing heat loss during the heating process and further improving the thermal efficiency of the heating device during the heating process.

[0071] Furthermore, both ends of each mounting plate are detachably connected to the two first plates 110 , and both ends of the limiting plate 200 are also detachably connected to the two first plates 110 , so that the mounting plate, the first plate 110 or the limiting plate 200 can be easily replaced.

[0072] For details, please refer to Figure 1-Figure 4 The limiting plate 200 includes a plurality of mounting grooves 210 spaced apart along a first direction, and the corrugated heating belt 310 has a plurality of unit belts 311 sequentially connected in the first direction, and each unit belt 311 is arranged in a mounting groove 210. That is to say, the stability of the corrugated heating belt 310 in the accommodating cavity 131 can be ensured by the mounting groove 210.

[0073] Specifically, a plurality of mounting grooves 210 spaced apart along the first direction are provided on one side of the limiting plate 200 in the third direction. The mounting grooves 210 are oriented parallel to the third direction, and the third direction, the second direction and the first direction are perpendicular to each other.

[0074] Optionally, the mounting groove 210 has a first inner wall (not shown in the figure), a second inner wall (not shown in the figure) and a third inner wall (not shown in the figure) connected in sequence at an angle, the first inner wall and the third inner wall are arranged in the first direction, the first inner wall and the third inner wall are used to limit the movement of the unit belt 311 in the first direction, and the second inner wall is used to limit the movement of the unit belt 311 in the third direction.

[0075] Of course, in some other embodiments, the number of limit plates 200 in each accommodating cavity 131 can be two, and the two limit plates 200 are arranged at intervals along the third direction in one accommodating cavity 131, and the two limit plates 200 are respectively located on both sides of the two corrugated heating belts 310 in the third direction, and the unit belts 311 of each corrugated heating belt 310 are respectively located in the installation grooves 210 of the two limit plates 200 on both sides in the third direction, so that the corrugated heating belt can be stably installed in the accommodating cavity 131.

[0076] That is, for each unit belt 311 of the corrugated heating belt 310, the corrugated heating belt 310 can approach the mounting groove 210 from the direction opposite to the direction of the mounting groove 210, so that each unit belt 311 is inserted into the plurality of mounting grooves 210 in a one-to-one correspondence. This can prevent the unit belts 311 from contacting each other, and also prevent the corrugated heating belt 310 from moving in the first direction.

[0077] Of course, in some other embodiments, the limiting plate 200 may further be provided with a plurality of mounting holes spaced apart along the first direction, and each unit belt 311 may be provided with a mounting hole, which can also limit the displacement of each unit belt 311 in the first direction.

[0078] Optionally, both ends of the mounting plate are respectively snap-fitted with the two first plate bodies 110 . It can be understood that since both ends of the mounting plate are respectively snap-fitted with the two first plate bodies 110 , the efficiency of assembly and disassembly of the mounting plate and the two first plate bodies 110 can be improved.

[0079] Of course, in some other embodiments, both ends of the mounting plate may also be connected to the two first plate bodies 110 respectively through threaded fasteners.

[0080] In detail, in the present embodiment, the plurality of mounting plates include two second plate bodies 122 and a plurality of partition plates 121, a receiving cavity 131 is formed between any two adjacent partition plates 121, and a receiving cavity 131 is also formed between the second plate body 122 and the partition plate 121 close to the second plate body 122, both ends of the partition plates 121 have second plug-in protrusions 1211, the first plate body 110 is provided with a plurality of plug-in holes 114 arranged at intervals along the second direction, the second plug-in protrusions 1211 are plugged into the plug-in holes 114, that is, the second plug-in protrusions 1211 at both ends of the partition plates 121 in the first direction are respectively plugged into and matched with the plug-in holes 114 of the two first plate bodies 110, which can limit the movement of the partition plates 121 in the first direction, thereby ensuring the stability of the entire mounting frame 100.

[0081] Among them, the two ends of the limiting plate 200 have a first plug-in protrusion 220, and the first plug-in protrusion 220 is plugged into the plug-in hole 114, that is, the two ends of the limiting plate 200 are also respectively plugged and matched with the plug-in holes 114 on the two first plate bodies 110, that is, the multiple plug-in holes 114 on the first plate body 110 can be matched with the first plug-in protrusion 220 of the limiting plate 200, and can also be matched with the second plug-in protrusion 1211 on the partition plate 121, and since a limiting plate 200 is arranged in each accommodating cavity 131, the plug-in holes 114 on the first plate body 110 that cooperate with the first plug-in protrusion 220 and the plug-in holes 114 that cooperate with the second plug-in protrusion 1211 are alternately arranged.

[0082] It should be noted that the plug-in hole 114 that cooperates with the first plug-in protrusion 220 and the plug-in hole 114 that cooperates with the second plug-in protrusion 1211 can be the same hole or different holes, which mainly adapt to the shapes of the first plug-in protrusion 220 and the second plug-in protrusion 1211 respectively.

[0083] The two second plates 122 are arranged at intervals along the second direction, and the multiple partition plates 121 are located between the two second plates 122. The two first plates 110 and the two second plates 122 jointly define an installation cavity 130, and an accommodating cavity 131 is also formed between the second plate 122 and the partition plate 121 close to the second plate 122. Both ends of the second plate 122 in the first direction are provided with a clamping portion 1221, and both ends of the first plate 110 in the second direction are provided with a matching portion 113 that is clamped and matched with the clamping portion 1221. It can be understood that through the setting of the second plate 122, the movement of the two first plates 110 in the first direction can be restricted. After restricting the movement of the two first plates 110 in the first direction, the movement of the installation plate arranged in the installation cavity 130 in the first direction can also be restricted, thereby effectively ensuring the stability of the installation frame 100 and avoiding the installation frame 100 from being scattered.

[0084] Optionally, the clamping portion 1221 is a clamping hole, and the matching portion 113 is an elastic clamping portion, which extends out of the clamping hole and abuts against the second plate body 122. It can be understood that during the installation of the second plate body 122 and the first plate body 110, that is, during the process of the elastic clamping portion inserting into the clamping hole, the elastic clamping portion will undergo elastic deformation until the elastic clamping portion extends out of the clamping hole, and then the elastic clamping portion will abut against the second plate body 122. Therefore, in other words, through the cooperation between the elastic clamping portion and the clamping hole, not only the movement of the first plate body 110 and the second plate body 122 in the first direction can be restricted, but also the movement of the first plate body 110 and the second plate body 122 in the second direction can be restricted.

[0085] Of course, in some other embodiments, the matching portion 113 may also be a clamping column, and the clamping column is clamped with the clamping hole.

[0086] Optionally, in order to increase the distance between the second plate body 122 and the partition plate 121 , flanges 111 are provided at both ends of the first plate body 110 in the second direction, the flanges 111 extend along the first direction, the mating portion 113 protrudes from the flanges 111 , and the second plate body 122 overlaps the flanges 111 .

[0087] To prevent the flange 111 from extending into the accommodating cavity 131 , the flange 111 of each first plate body 110 is oriented away from the other first plate body 110 .

[0088] The partition plate 121 has first notches 1212 at both ends in the first direction for the corrugated heating belt 310 to pass through, and the limiting plate 200 has second notches 230 at both ends in the first direction for the corrugated heating belt 310 to pass through. The first notches 1212 on the partition plate 121 and the second notches 230 on the limiting plate 200 are arranged in a one-to-one correspondence.

[0089] The corrugated heating belts 310 in multiple accommodating cavities 131 form a corrugated integrated resistance belt 300. It can be understood that the corrugated heating belt 310 in each accommodating cavity 131 has a first end and a second end in the first direction. For any three adjacent accommodating cavities 131, the first end of the corrugated heating belt 310 in the outermost accommodating cavity 131 of the three accommodating cavities 131 passes through the adjacent second notch 230 and the first notch 1212 in sequence and is connected to the first end in the accommodating cavity 131 at the middle position, and the second end of the corrugated heating belt 310 in the accommodating cavity 131 at the middle position passes through the adjacent second notch 230 and the first notch 1212 in sequence and is connected to the corrugated heating belt 310 in the last accommodating cavity 131.

[0090] Both ends of the integrated resistance band 300 are connected to the wire 500 through the riveted terminal 400. The maximum area of ​​the riveted terminal 400 is in contact with the resistance band.
