The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] like Figure 1-5 As shown, a heat-insulating shell comprises an upper cover 1 and a lower cover 2, both of which are made of elastic heat-insulating material, and two or more clamping columns 3. The outer wall of the upper cover 1 is evenly distributed with at least two upper clamping parts 11 along the circumference of its opening. The upper clamping part 11 is provided with a clamping hole 12 penetrating through both sides of the top and bottom thereof. The end of the upper clamping part 11 away from the upper cover 1 is provided with a notch 13 connected to the clamping hole 12. The width of the notch 13 is smaller than the inner diameter of the clamping hole 12. The outer wall of the lower cover 2 is evenly distributed with at least two lower clamping parts along the circumference of its opening. 21, the upper cover 1 can cover the lower cover 2 with each other, and when the upper cover 1 and the lower cover 2 cover each other, the lower clamping portion 21 and the upper clamping portion 11 are symmetrical with respect to the abutting surface of the lower cover 2 and the upper cover 1, at this time, the top wall of the upper clamping portion 11 and the top wall of the lower clamping portion 21 are at a distance D, and clamping blocks 31 are provided at both ends of the clamping column 3, the diameter of the clamping block 31 is larger than the inner diameter of the clamping hole 12, the length of the clamping column 3 is D, the diameter of the clamping column 3 is larger than the width of the notch 13, and the clamping column 3 can pass through the notch 13 and be sleeved in the clamping hole 12.

[0029] Specifically, the width of the notch 13 refers to the distance between the inner walls on both sides of the notch 13; the side walls of the upper cover 1 and the lower cover 2 are both provided with avoidance openings 5 ​​for routing the heating element; the upper cover 1 and the lower cover 2 can be made of any heat-insulating and fire-proof material with a certain elasticity. In this embodiment, the material is preferably a mixture of glass fiber, aerogel, and kaolin. The side wall thickness of the upper cover 1 and the lower cover 2 is 1mm to 10mm. The upper cover 1 and the lower cover 2 made of the above material can withstand a high temperature of up to 600 degrees, and a long-term temperature resistance of about 350 degrees. They can effectively isolate the heat of common heating elements and are durable.

[0030] In the present embodiment, the contour line of the cross section of the clamping hole 12 is an arc. When the upper cover 1 and the lower cover 2 are covered with each other, they will enclose a receiving cavity for placing the heating element. When in use, the heating element is first placed on the inner side of the upper cover 1 or the lower cover 2, and then the upper cover 1 and the lower cover 2 are covered with each other, so that the heating element can be enclosed in the receiving cavity. At this time, the corresponding upper clamping portion 11 and the lower clamping portion 21 will be aligned in the opening direction of the upper cover 1, and the two clamping holes 12 are aligned and connected. The clamping column 3 can be simultaneously clamped into the inner sides of the two clamping holes 12 through the notch 13. When the clamping column 3 passes through the notch 13, it will squeeze the inner walls on both sides of the notch 13. At this time, the corresponding upper clamping portion 11 and the lower clamping portion 21 will be adaptively deformed. When the clamping column 3 passes through the notch 13 After that, the deformed parts of the upper clamping part 11 and the lower clamping part 21 will be restored, so that the inner wall of the clamping hole 12 is close to the side wall of the clamping column 3, and the inner walls on both sides of the notch 13 are used to limit the clamping column 3 from being separated from the clamping hole 12. At the same time, the clamping block 31 at one end of the clamping column 3 will abut against the top wall of the upper clamping part 11, and the clamping block 31 at the other end of the clamping column 3 will abut against the top wall of the lower clamping part 21. Therefore, the upper clamping part 11 and the lower clamping part 21 will not be able to separate from each other along the axial direction of the clamping column 3, so that the upper cover 1 and the lower cover 2 are relatively fixed by the cooperative connection of more than two groups of upper clamping parts 11, lower clamping parts 21, and clamping columns 3, avoiding the use of gluing or screwing to connect the upper cover 1 and the lower cover 2, making the connection operation between the two easier and faster.

[0031] In one embodiment, at least two positioning posts may be provided on the inner bottom wall edge of the upper cover 1, and the positioning posts are provided along the opening direction of the upper cover 1. At least two positioning holes may be provided on the lower cover 2 and the inner bottom wall edge. When the upper cover 1 covers the lower cover 2, the positioning posts may be inserted into the positioning holes one by one, thereby assisting the upper cover 1 and the lower cover 2 to be positioned and covered (not shown in the drawings).

[0032] Furthermore, a groove 15 is provided at the top end of the inner wall of the upper cover 1 along the circumference of its opening, and a convex edge 22 is provided at the top end of the inner wall of the lower cover 2 along the circumference of its opening. When the upper cover 1 and the lower cover 2 are covered with each other, the convex edge 22 will be engaged in the groove 15, thereby limiting the movement of the upper cover 1 and the lower cover 2 on the abutting surface thereof. Combined with the movement restriction of the upper cover 1 and the lower cover 2 in the vertical direction of the abutting surface thereof by the block 31, the connection between the upper cover 1 and the lower cover 2 when they are covered with each other is made more stable.

[0033] Furthermore, when the upper cover 1 and the lower cover 2 are covered with each other, the bottom wall of the upper clamping portion 11 abuts against the bottom wall of the corresponding lower clamping portion 21, thereby increasing the indirect abutment surface between the upper cover 1 and the lower cover 2, and improving the connection tightness and stability between the two.

[0034] Specifically, when the upper cover 1 and the lower cover 2 are covered with each other, the side wall of the upper clamping portion 11 facing the lower clamping portion 21 is the bottom wall, and the side wall of the upper clamping portion 11 facing away from the lower clamping portion 21 is the top wall, and the same is true for the lower clamping portion 21.

[0035] Furthermore, a first inclined surface 14 is provided on the top wall of the upper clamping portion 11 at the notch 13. When the upper cover 1 and the lower cover 2 are covered with each other, since the length of the clamping column 3 and the distance between the top wall of the upper clamping portion 11 and the top wall of the lower clamping portion 21 are all D, when the clamping column 3 is clamped into the two clamping holes 12 through the two notches 13 at the same time, if the axis of the clamping column 3 is not parallel to the axis of the clamping hole 12, a side wall of the clamping block 31 close to the clamping column 3 is easily obstructed by the top wall of the upper clamping portion 11 or the lower clamping portion 21, resulting in an unsmooth clamping process of the clamping column 3. The addition of the first inclined surface 14 makes it easier for the clamping block 31 to slide along the first inclined surface 14 to the corresponding top wall of the upper clamping portion 11 or the lower clamping portion 21, thereby reducing interference during the clamping process and improving the operating experience.

[0036] Furthermore, a second inclined surface 32 is provided on the edge of a side wall of the clamping block 31 close to the clamping column 3. Similar to the above-mentioned first inclined surface 14, when the clamping column 3 is clamped into the clamping hole 12, the second inclined surface 32 of the clamping block 31 can slide relative to the outward end of the top wall of the corresponding upper clamping portion 11 or the lower clamping portion 21 until a side wall of the clamping block 31 close to the clamping column 3 abuts against the top wall of the corresponding upper clamping portion 11 or the lower clamping portion 21, thereby reducing interference during the clamping process.

[0037] Furthermore, the side wall of the card column 3 is circumferentially distributed with a plurality of anti-skid grooves 33, and the anti-skid grooves 33 are all arranged along the axial direction of the card column 3. Since the materials of the upper cover 1 and the lower cover 2 have a certain elasticity, when the card column 3 is inserted into the card hole 12, the corresponding part of the inner wall of the card hole 12 can be embedded in the anti-skid groove 33 through deformation, thereby increasing the contact area between the inner wall of the card hole 12 and the card column 3, further improving the static friction between the card column 3 and the inner wall of the card hole 12, preventing the card column 3 from easily detaching from the card hole 12, and improving the connection stability between the upper cover 1 and the lower cover 2.

[0038] Furthermore, the inner wall of the upper cover 1 is provided with a plurality of ribs 6, which are evenly distributed along the edge of the inner bottom wall of the upper cover 1, the front half of the ribs 6 are arranged on the inner side wall of the upper cover 1, and the rear half of the ribs 6 are arranged on the inner bottom wall of the upper cover 1. When the upper cover 1 and the lower cover 2 are covered with each other, the inner wall of the lower cover 2 and the inner wall of the upper cover 1 are symmetrical with respect to the abutting surface between the lower cover 2 and the upper cover 1 as the center.

[0039] Furthermore, the ribs 6 are arranged along the angle between the inner side wall and the inner bottom wall of the upper cover 1 at the location.

[0040] Specifically, when the upper cover 1 and the lower cover 2 are covered with each other and the heating element is enclosed in the accommodating cavity, the side wall of the heating element will abut against the ribs 6 in the accommodating cavity. The heating element is supported by the ribs 6, so that the inner wall of the upper cover 1 and the inner wall of the lower cover 2 are spaced from the heating element, avoiding direct contact between the heating element and the inner wall of the upper cover 1 and the inner wall of the lower cover 2, and reducing the contact area between the heating element and the inner wall of the upper cover 1 and the inner wall of the lower cover 2, thereby reducing the heat conduction efficiency between the heating element and the upper cover 1 and the lower cover 2, and further improving the heat insulation capacity of the upper cover 1 and the lower cover 2 to the heating element.

[0041] Furthermore, the upper cover 1 and the lower cover 2 are both made of a mixture of glass fiber, aerogel and kaolin.

[0042] Furthermore, the upper clamping portion 11 is integrally formed with the upper cover 1 , and the lower clamping portion 21 is integrally formed with the lower cover 2 .

[0043] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
