The flexible connector 20 is adapted to allow the first insulation board 1a and the second insulation board 1b to switch between a retracted state and an unfolded state through flexible deformation.

[0063] The thermal insulation appliance 10 of this utility model includes at least two thermal insulation boards, namely a first thermal insulation board 1a and a second thermal insulation board 1b. To facilitate storage, in this embodiment, the first thermal insulation board 1a and the second thermal insulation board 1b are connected by a flexible connector 20. To ensure stable connection between the first thermal insulation board 1a and the second thermal insulation board 1b and the flexible connector 20, in this embodiment, a first mating portion 10a and a second mating portion 10b are respectively provided on one side of the first thermal insulation board 1a and one side of the second thermal insulation board 1b, spaced apart along the thickness direction of the thermal insulation appliance 10.

Then, other methods are used to fix the two together. This setting makes it easier and more accurate to install the fixing member 12 onto the bottom shell 111, and also prevents the two from shifting after the subsequent installation is completed.

[0072] In one embodiment, such as Figure 5As shown, the fixing member 12 is provided with the positioning part 122, the first enclosure plate 1112 is provided with the first positioning groove 1112a, the snap-fit ​​section 22 is provided with the second positioning groove 223, the positioning part 122 is snapped into the first positioning groove 1112a and the second positioning groove 223, the second positioning groove 223 and the first positioning groove 1112a are arranged along the width direction of the heat insulation body 11, a part of the positioning part 122 is snapped into the first positioning groove 1112a, and a part of the positioning part 122 is snapped into the second positioning groove 223; and / or, the fixing member 12 is provided with a support platform 123, the support platform 123 is provided with a mounting hole 124, the heat insulation appliance 10 includes a locking member 13, the locking member 13 passes through the mounting hole 124 and is connected to the second enclosure plate 1113, and the support platform 123 abuts against the second enclosure plate 1113. In this embodiment, a positioning part 122 is provided on the fixing member 12, a first positioning groove 1112a is provided on the first surrounding plate 1112 of the bottom shell 111, and a second positioning groove 223 corresponding to the positioning part 122 is provided on the snap-fit ​​section 22 of the flexible connector 20. When the fixing member 12 is provided on the bottom shell 111, a part of the positioning part 122 is snapped into the first positioning groove 1112a, and the other part is snapped into the second positioning groove 223. In this embodiment, the first positioning groove 1112a and the second positioning groove 223 are arranged along the width direction of the heat insulation body 11, and the positioning part 122 extends along the width direction of the heat insulation body 11. With this arrangement, not only can the position of the fixing member 12 relative to the bottom shell 111 be prevented, but the position of the flexible connector 20 can also be prevented from being affected by external forces. In this embodiment, a support platform 123 is also provided on the surface of the fixing member 12, which resembles the second enclosure 1113. An installation hole 124 is provided on the support platform 123. The fixing member 12 can be connected to the bottom shell 111 through the installation hole 124 via a locking member 13. The support platform 123 can abut against the second enclosure 1113 when the fixing member 12 is installed on the bottom shell 111. This arrangement prevents the fixing member 12 from getting too close to the second enclosure 1113 and damaging the flexible connector 20 located between them, thus significantly increasing the service life of the flexible connector 20. In other embodiments, to further enhance the above effects, multiple positioning parts 122, first positioning grooves 1112a, and second positioning grooves 223 are provided, with each of these multiple positioning parts 122, first positioning grooves 1112a, and second positioning grooves 223 spaced apart along the length of the insulation appliance 10.

[0073] In one embodiment, such as Figure 5As shown, the flexible connector 20 is provided with a first wire-passing hole 23, which passes through the snap-fit ​​sections 22 on both sides of the connecting section 21 along the width direction of the flexible connector 20. The heat insulation body 11 is provided with a second wire-passing hole 1112b corresponding to the first wire-passing hole 23. The first wire-passing hole 23 and the second wire-passing hole 1112b are used for the wire to pass through in sequence; and / or, the fixing member 12 is elongated and extends along the length direction of the heat insulation body 11. In this embodiment, the heat preservation device 10 includes a first heat preservation plate 1a and a second heat preservation plate 1b, and each heat preservation plate is provided with a heating element 113. The operation of the heating element 113 requires electrical energy. In this embodiment, a first wire passage hole 23 is provided in the flexible connector 20, which passes through both sides of the connecting section 21 along the width direction of the flexible connector 20. A second wire passage hole 1112b corresponding to the first wire passage hole 23 is provided in the heat preservation body 11. In this embodiment, the second wire passage hole 1112b... 12b is set on the bottom plate 1111 of the groove forming the mounting groove 10d of the insulation body 11. Due to the setting of the first wire hole 23 and the second wire hole 1112b, the heating element 113 in the first insulation plate 1a and the second insulation plate 1b can be electrically connected by passing the wire through the first wire hole 23 and the second wire hole 1112b respectively. With this setting, the controller 30 can better control the heating element 113 in the first insulation plate 1a and the second insulation plate 1b at the same time, and the wire is laid more neatly.

[0074] In one embodiment, such as Figure 7As shown, the projections of the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 along the thickness direction of the heat insulation appliance 10 at least partially overlap; and / or, the connecting segment 21 and the snap-fit ​​segments 22 disposed on both sides of the connecting segment 21 are integral structures. In order to enable the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 to be better shaped, or to enable the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 to better offset external forces, in this embodiment, the projections of the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 along the thickness direction of the heat insulation appliance 10 overlap, so that the snap-fit ​​segment 22 and the connecting segment 21 form a "T"-shaped structure, so that the snap-fit ​​segment 22 has a better snap-fit ​​effect with the first mating portion 10a and the second mating portion 10b. In this embodiment, the connecting segment 21 of the flexible connector 20 and the snap-fit ​​segments 22 disposed on both sides of the connecting segment 21 are integral structures. The connecting segment 21 and the snap-fit ​​segments 22 can be integrally injection molded. Furthermore, the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 in the snap-fit ​​segment 22 can be arranged in an alternating manner along the thickness direction of the insulation appliance 10, or they can be arranged in a corresponding manner. There are no specific limitations on the molding method of the flexible connector 20 and the arrangement of the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 in the snap-fit ​​segment 22 along the insulation appliance 10.

[0075] In one embodiment, such as Figure 7 As shown, the flexible connector 20 includes at least two snap-fit ​​sections 22 on both sides. The two snap-fit ​​sections 22 located on the same side of the flexible connector 20 are spaced apart along the width direction of the insulation appliance 10. The two snap-fit ​​sections 22 on both sides of the flexible connector 20 are respectively snapped into the first insulation plate 1a and the second insulation plate 1b. In this embodiment, at least two snap-fit ​​sections 22 are provided on both sides of the flexible connector 20. That is, at least two snap-fit ​​sections 22 are provided on one side of the flexible connector 20. The two snap-fit ​​sections 22 are spaced apart along the width direction of the insulation appliance 10. In this embodiment, the two snap-fit ​​sections 22 on both sides of the flexible connector 20 are respectively snapped into the first insulation plate 1a and the second insulation plate 1b. The snap-fit ​​effect between the two snap-fit ​​sections 22 and the first mating part 10a and the second mating part 10b on the first insulation plate 1a and the second insulation plate 1b is more stable. The first snap-fit ​​part 221 and the second snap-fit ​​part 222 in each snap-fit ​​section 22 can be arranged in an alternating manner along the thickness direction of the insulation appliance 10, or they can be arranged in a corresponding manner. There is no specific limitation on this.

[0076] In one embodiment, such as Figure 7As shown, the projections of the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222 of each snap-fit ​​segment 22 along the thickness direction of the insulation appliance 10 at least partially overlap. To ensure that the two snap-fit ​​segments 22 respectively provided on both sides of the flexible connector 20 have the same effect as in the single embodiment described above, in this embodiment, the first snap-fit ​​portion 221 and the second snap-fit ​​segment 22 of the two snap-fit ​​segments 22 located on the same side of the flexible connector 20 both overlap along the thickness direction of the insulation appliance 10. Thus, the two snap-fit ​​segments 22 can form an "I"-shaped structure on one side of the flexible connector 20. The two snap-fit ​​segments 22 arranged in this way can better engage with the first mating portion 10a and the second mating portion 10b provided on the first insulation plate 1a or the second insulation plate 1b, making the connection between the two more stable.

[0077] In one embodiment, the flexible connector 20 further includes a connecting portion, through which two snap-fit ​​segments 22 located on the same side of the flexible connector 20 are connected; and / or, at least two snap-fit ​​segments 22, the connecting portion, and the connecting segment 21 located on both sides of the flexible connector 20 are integrally formed. In this embodiment, the flexible connector 20 further includes a connecting portion, wherein two snap-fit ​​segments 22 located on the same side of the flexible connector 20 are connected through the connecting portion. In this embodiment, the two snap-fit ​​segments 22 located on both sides, the connecting portion of the two snap-fit ​​segments 22 located on the same side, and the connecting segment 21 in the flexible connector 20 are integrally formed by injection molding.

[0078] In one embodiment, both the first insulation board 1a and the second insulation board 1b include an upper shell (not shown in the figure) and a lower shell (not shown in the figure), the upper shell covers the lower shell, the first mating part 10a is disposed on the upper shell, the second mating part 10b is disposed on the lower shell, and the snap-fit ​​section 22 is disposed between the upper shell and the lower shell; and / or, the insulation appliance 10 is an insulation cutting board. In this embodiment, both the first insulation plate 1a and the second insulation plate 1b are composed of an upper shell and a lower shell, wherein the upper shell covers the lower shell, and a receiving cavity 10c, identical to that described above, is formed between the upper shell and the lower shell. This receiving cavity 10c is used to house the heating element 113. In this embodiment, the first mating part 10a is located on the side of the upper shell facing the lower shell, and the second mating part 10b is located on the side of the lower shell facing the upper shell. The flexible connector 20 is located between the upper shell and the lower shell, that is, between the first mating part 10a and the second mating part 10b. The flexible connector 20 is still engaged with the first mating part 10a and the second mating part 10b through the first engaging part 221 and the second engaging part 222 in the engaging sections 22 on both sides, thereby achieving the same effect as described above. In this embodiment, the heat preservation appliance 10 is a heat preservation cutting board, which can be used to keep food warm or heat it when the temperature is low.

[0079] In one embodiment, in the unfolded state, the length of the connecting segment 21 exposed between the first insulation board 1a and the second insulation board 1b is D1, the insulation appliance 10 has a bearing surface and a supporting surface, the distance from the connecting segment 21 to the bearing surface is D2, and D1 > D2; and / or, the distance from the connecting segment 21 to the supporting surface is D3, and D1 > D3. To ensure that the first insulation board 1a and the second insulation board 1b are not affected by the folding direction when folded and stored, in this embodiment, the length between the exposed connecting segment 21 of the flexible connector 20 and the first insulation board 1a and the second insulation board 1b is defined as D1. In this embodiment, the insulation appliance 10 has a bearing surface and a supporting surface, that is, both the first insulation board 1a and the second insulation board 1b have a bearing surface and a supporting surface, wherein the bearing surface is located above the supporting surface. The supporting surface is used to support the table or the ground, while the bearing surface is used to place food. In this embodiment, the distance of the connecting segment 21 from the bearing surface is defined as D2, wherein D1 is set to be greater than D2. This setting allows the first insulation board 1a and the second insulation board 1b to be easily folded by fitting the two bearing surfaces together. In another embodiment, the distance of the connecting segment 21 from the supporting surface is defined as D3, wherein D1 is set to be greater than D3. This setting allows the first insulation board 1a and the second insulation board 1b to be easily folded by fitting the two supporting surfaces together. In other embodiments, D1 in the above data is set to be greater than D2 and D3, which allows the first insulation plate 1a and the second insulation plate 1b to be easily folded regardless of their orientation.

[0080] In one embodiment, such as Figure 7 As shown, the first mating part 10a includes two first protrusions 1115, which are spaced apart along the width direction of the heat insulation appliance 10, and the first snap-fit ​​part 221 is disposed between the two first protrusions 1115; and / or, the second mating part 10b includes two second protrusions 121, which are spaced apart, and the second snap-fit ​​part 222 is disposed between the two second protrusions 121. In this embodiment, the first mating part 10a includes two first protrusions 1115, which are disposed on the outer side of the bottom shell 111 and extend downward along the thickness direction of the heat insulation appliance 10. The two first protrusions 1115 are spaced apart along the width direction of the heat insulation appliance 10 to form a snap-fit ​​groove, and the first snap-fit ​​part 221 of the snap-fit ​​section 22 in the flexible connector 20 snaps between the two first protrusions 1115. In another embodiment, the second mating part 10b includes two second protrusions 121, which are disposed on the outer side of the bottom shell 111 and extend upward along the thickness direction of the insulation appliance 10. Two first protrusions 1115 are spaced apart along the width direction of the insulation appliance 10 to form another snap-fit ​​groove. The second snap-fit ​​portion 222 of the snap-fit ​​section 22 in the flexible connector 20 snaps into the two second protrusions 121. In other embodiments, the above two methods are combined into the same scheme, wherein the first mating part 10a and the second mating part 10b are respectively provided correspondingly.

[0081] In one embodiment, such as Figure 7As shown, the first mating part 10a and / or the second mating part 10b have a first protrusion 10e on the surface facing the flexible connector 20. The first protrusion 10e abuts against the snap-fit ​​section 22, causing the snap-fit ​​section 22 to undergo elastic deformation. And / or, the first snap-fit ​​part 221 and / or the second snap-fit ​​part 222 have a second protrusion 224 on the surface facing the heat preservation appliance 10. The second protrusion 224 abuts against the heat preservation appliance 10 and undergoes elastic deformation. To prevent the broth from spilling out when food is placed above the heat preservation appliance 10 for heat preservation or heating, and from entering the mounting groove 10d through the gap between the flexible connector 20 and the first heat preservation plate 1a and the second heat preservation plate 1b, which would make cleaning inconvenient due to the small space in the mounting groove 10d, this design is designed to avoid this problem. In this embodiment, a first protrusion 10e is provided on the surface of the first mating part 10a facing the connecting section 21 of the flexible connector 20 to seal the surface between the first mating part 10a and the connecting section 21; or, a first protrusion 10e is also provided on the other surface of the second mating part 10b facing the connecting section 21 of the flexible connector 20 to seal the other surface between the first mating part 10a and the connecting section 21; or, both of the above methods are used simultaneously to seal the upper and lower surfaces of the first mating part 10a and the flexible connector 20 along the thickness direction of the insulation appliance 10. In this embodiment, the first protrusion 10e can cause the flexible connector 20 to deform when it contacts the flexible connector 20, thereby achieving a seal. In another embodiment, a second protrusion 224 is provided on the surface of the first snap-fit ​​portion 221 facing the heat preservation device 10, so that when the first snap-fit ​​portion 221 abuts against the first mating portion 10a, the gap between the two is sealed to prevent external liquid from entering; or, a second protrusion 224 is also provided on the other surface of the second snap-fit ​​portion 222 facing the heat preservation device 10, so that when the second snap-fit ​​portion 222 abuts against the second mating portion 10b, the gap between the two is sealed to prevent external liquid from entering; or, both of the above methods are used at the same time to seal the flexible connector 20 and both the first mating portion 10a and the second mating portion 10b. This arrangement can effectively prevent external liquid from penetrating through the gap between the flexible connector 20 and the first mating portion 10a or the second mating portion 10b, which would make it difficult to clean later.

The connection can be achieved by threading through a screw, or by clamping with an external component to achieve the connection with the second mating part 10b. No specific limitation is made in this regard. In this embodiment, the flexible connector 20 is used to connect the first insulation board 1a and the second insulation board 1b, so that the first insulation board 1a and the second insulation board 1b can be folded and stored through the flexible characteristics of the flexible connector 20.
