[0029] In order to make the technical problems, technical schemes and beneficial effects solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0030] In the description of the utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0031] As shown in Figure 1 and Figure 2 The utility model embodiment provides a heating bag 10, which comprises a clamping assembly 1 and a heating assembly 2; the clamping assembly 1 clamps the heating assembly 2 to fix the heating assembly 2; the heating assembly 2 can heat when powered on to heat the target object.

[0032] As shown in Figure 3 The clamping assembly 1 comprises a first clamping part 11, a second clamping part 12 and a connecting part 13; the first clamping part 11 and the second clamping part 12 are respectively connected to both ends of the connecting part 13 in the height direction and are used to clamp the heating assembly 2; in addition, the connecting part 13 can be elastically deformed in the height direction of the connecting part 13.

[0033] In Figure 3 The height direction of the connecting part 13 can be parallel to the Z axis in the direction shown.

[0034] In this embodiment, after assembly, the heating assembly 2 is located between the first clamping part 11 and the second clamping part 12 in the height direction of the connecting part 13 and abuts against the first clamping part 11 and the second clamping part 12 respectively. That is, the heating assembly 2 clamped by the clamping assembly 1 is actually clamped by the first clamping part 11 and the second clamping part 12.

[0035] Since the connecting part 13 can be elastically deformed, the spacing between the first clamping part 11 and the second clamping part 12 can be changed to compensate for the error generated during production, so that it can be adapted to clamp heating assemblies 2 of different thicknesses. The thickness of the heating assembly 2 refers to its size in the Z axis direction.

[0036] Meanwhile, when the heating bag 10 is installed into the installation groove 201 of the shell 20, if the width of the installation groove 201 has a machining error, the error can be compensated by the elastic deformation of the connecting portion 13. That is, the present embodiment can be adapted to installation grooves 201 of different widths. The width of the installation groove 201 refers to the dimension of the installation groove 201 in the Z-axis direction.

[0037] As shown in FIG. 1, in an embodiment, the connecting portion 13 comprises a pleat structure 131, so that the connecting portion 13 can be elastically deformed in the height direction of the connecting portion 13. That is, in the present embodiment, the connecting portion 13 has better elastic properties in the height direction thereof by virtue of the pleat structure 131, thereby improving the compensation effect of the clamping assembly 1 on production errors. Figure 3

[0038] In an embodiment, the pleat structure 131 is a structure formed by bending deformation of the connecting portion 13. For example, the connecting portion 13 can be bent in different directions by bending to form the pleat structure 131.

[0039] As shown in FIG. 2, in an embodiment, the pleat structure 131 has a first recess 132 and a second recess 133, the first recess 132 and the second recess 133 are respectively located on both sides in the thickness direction of the connecting portion 13 and are arranged in sequence in the height direction of the connecting portion 13. In the embodiment, the thickness direction of the connecting portion 13 is parallel to the X-axis. Figure 3 Figure 3

[0040] In addition, when the number of the first recesses 132 is a plurality and / or the number of the second recesses 133 is a plurality, the first recesses 132 and the second recesses 133 are alternately arranged in sequence in the height direction of the connecting portion 13. Here, "a plurality" means more than or equal to two, and the meaning of the term "a plurality" is the same in each embodiment, which will not be described hereinafter.

[0041] At this time, the number of the first recesses 132 is one more than the number of the second recesses 133, or the number of the second recesses 133 is one more than the number of the first recesses 132, or the number of the first recesses 132 is the same as the number of the second recesses 133.

[0042] When the number of the first recesses 132 is one, if the number of the second recesses 133 is a plurality, the actual number of the second recesses 133 is two, and at this time, in the height direction of the connecting portion 13, the first recess 132 is located between the two second recesses 133. When the number of the second recesses 133 is one, if the number of the first recesses 132 is a plurality, the actual number of the first recesses 132 is two, and at this time, in the height direction of the connecting portion 13, the second recess 133 is located between the two first recesses 132.

[0043] ​​​In addition, both the first recess 132 and the second recess 133 can be formed by bending and deforming the connecting portion 13.

[0044] In one embodiment, at least a portion of the pleated structure 131 is an S-shaped structure, in which case the first recess 132 and the second recess 133 are both arc-shaped grooves. In actual products, the connecting portion 13 may have one S-shaped structure or multiple S-shaped structures. One S-shaped structure includes a first recess 132 and a second recess 133.

[0045] Of course, the first recess 132 and the second recess 133 can also be other shapes. For example, in other embodiments, at least a portion of the pleated structure 131 is a Z-shaped structure, in which case the first recess 132 and the second recess 133 are both V-shaped grooves.

[0046] like Figure 3 As shown, in one embodiment, in the thickness direction of the connecting portion 13 (i.e., in the X-axis direction), the first clamping portion 11 and the second clamping portion 12 are both located on the same side of the connecting portion 13 to clamp the heating component 2 located between the first clamping portion 11 and the second clamping portion 12.

[0047] In one embodiment, the first clamping part 11, the second clamping part 12, and the connecting part 13 are an integral structure, which facilitates the production and manufacturing of the clamping assembly 1. The clamping assembly 1 can be formed from a sheet metal through a bending operation. Of course, in other embodiments, the first clamping part 11, the second clamping part 12, and the connecting part 13 can also be separate structures, assembled together by welding or by connecting them with corresponding parts.

[0048] like Figure 3 As shown, in one embodiment, along the direction from the first clamping portion 11 to the connecting portion 13 (i.e. Figure 3 (in the opposite direction of the X-axis arrow), the maximum dimension of the first clamping part 11 in the height direction (i.e., the Z-axis direction) of the connecting part 13 gradually decreases; and along the direction from the second clamping part 12 to the connecting part 13 (i.e., in the opposite direction of the X-axis arrow), the maximum dimension of the first clamping part 11 gradually decreases; and along the direction from the second clamping part 12 to the connecting part 13 (i. Figure 3 (In the opposite direction of the X-axis arrow), the maximum dimension of the second clamping part 12 gradually decreases in the height direction of the connecting part 13. After the heating pack 10 is assembled, the closer it is to the connecting part 13, the smaller its dimension in the Z-axis direction. When the heating pack 10 is installed in the mounting groove 201, the end where the connecting part 13 is located is installed into the mounting groove 201 first. As the heating pack 10 continues to penetrate deeper into the mounting groove 201, the heating pack 10 is increasingly gripped by the groove wall of the mounting groove 201. This can improve the heat transfer effect between the heating pack 10 and the housing 20, so that the heat generated by the heating pack 10 can be transferred to the housing 20 in a timely manner.

[0049] In an embodiment, in the Z-axis direction, the surface of the first clamping part 11 close to the second clamping part 12 and the surface of the first clamping part 11 away from the second clamping part 12 are both planes, and both are parallel to the Y-axis. The distance between the surface of the first clamping part 11 close to the second clamping part 12 and the surface of the first clamping part 11 away from the second clamping part 12 is the size of the first clamping part 11 in the Z-axis direction. In addition, the width direction of the connecting part 2 is parallel to the Y-axis, and the X-axis, the Y-axis and the Z-axis are perpendicular to each other.

[0050] In an embodiment, in the Z-axis direction, the surface of the second clamping part 12 close to the first clamping part 11 and the surface of the second clamping part 12 away from the first clamping part 11 are both planes, and both are parallel to the Y-axis. The distance between the surface of the second clamping part 12 close to the first clamping part 11 and the surface of the second clamping part 12 away from the first clamping part 11 is the size of the second clamping part 12 in the Z-axis direction.

[0051] As shown in FIGS. 1, 2 and 3, in an embodiment, the heating assembly 2 further comprises a first clamping part 11 and a second clamping part 12. Figure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, in an embodiment, the heating assembly 2 further comprises a first clamping part 11 and a second clamping part 12.

[0052] When the first clamping part 11 is a metal part, the heat transfer efficiency between the first clamping part 11 and the shell 20 is high, thereby improving the heat transfer efficiency between the clamping assembly 1 and the shell 20, and effectively avoiding the problem of dry burning of the heating assembly 2. Similarly, when the first clamping part 11 and the connecting part 13 are metal parts, the heat transfer efficiency between the clamping assembly 1 and the shell 20 can also be improved.

[0053] It should be noted that during work, the heat generated by the heating assembly 2 can be transmitted to the clamping assembly 1 through the insulating part 3.

[0054] Preferably, the first clamping part 11, the second clamping part 12 and the connecting part 13 are metal parts.

[0055] The insulating part 3 between the first clamping part 11 and the heating assembly 2, the insulating part 3 between the second clamping part 12 and the heating assembly 2, and the insulating part 3 between the connecting part 13 and the heating assembly 2 can be one part. At this time, the insulating part 3 can be a U-shaped structure, and the first clamping part 11, the second clamping part 12 and the connecting part 13 all have part of the structure of the insulating part 3.

[0056] Alternatively, the insulating part 3 between the first clamping part 11 and the heating component 2, the insulating part 3 between the second clamping part 12 and the heating component 2, and the insulating part 3 between the connecting part 13 and the heating component 2 are all independent parts.

[0057] Of course, in other embodiments, only one or two of the first clamping part 11, the second clamping part 12, and the connecting part 13 may be metal parts.

[0058] In one embodiment, the insulating member 3 is elastic to fill the gap between the heating component 2 and the clamping component 1, thereby improving the heat transfer efficiency between them. Specifically, the insulating member 3 may be a silicone pad, etc.

[0059] like Figure 2 As shown, in one embodiment, the heating component 2 includes a PTC heating core 21. PTC is short for Positive Temperature Coefficient. This embodiment's design prevents the heating component 2 from generating excessively high temperatures and also reduces the heat generated by the heating component 2 when the ambient temperature is too high.

[0062] In one embodiment, in the Z-axis direction, the first electrode plate 22 and the second electrode plate 23 are respectively disposed on both sides of the PTC heating core 21.

[0063] In addition, the PTC heating core 21 has a sheet-like structure, with the first electrode sheet 22 and the second electrode sheet 23 both attached to the PTC heating core 21.

Simultaneously, the first electrode plate 22 and the second electrode plate 23 are both connected to the first positioning block 24 and the second positioning block 25; that is, both ends of the first electrode plate 22 are connected to the first positioning block 24 and the second positioning block 25, and both ends of the second electrode plate 23 are connected to the first positioning block 24 and the second positioning block 25.

[0065] As shown in Figure 2 The first positioning block 24 and the second positioning block 25 are spaced apart along the X axis, the first positioning block 24 is provided with a first positioning structure 241 for cooperating with and positioning one end of the PTC heating core 21, and the second positioning block 25 is provided with a second positioning structure 251 for cooperating with and positioning the other end of the PTC heating core 21.

[0066] Specifically, the first positioning structure 241 is a first positioning groove provided on the surface of the first positioning block 24 close to the second positioning block 25, wherein the first positioning groove 241 penetrates the first positioning block 24 along the Z axis; the second positioning structure 251 is a second positioning groove provided on the surface of the second positioning block 25 close to the first positioning block 24, wherein the second positioning groove 251 penetrates the second positioning block 25 along the Z axis; and the two ends of the PTC heating core 21 are arranged in the first positioning groove 241 and the second positioning groove 251 respectively.

[0067] Meanwhile, in the Y axis direction, the two side walls of the first positioning groove 241 can abut against the PTC heating core 21, and the two side walls of the second positioning groove 251 can abut against the PTC heating core 21.

[0068] In addition, the first positioning block 24 and the second positioning block 25 can be provided with structures for positioning the first electrode sheet 22 and the second electrode sheet 23, so as to limit the positions of the first electrode sheet 22 and the second electrode sheet 23 relative to the PTC heating core 21 in the X axis and Y axis directions.

[0069] It should be understood that the PTC heating core 21 described above can also be replaced by other elements capable of generating heat by being electrified.
