Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A cooker 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 14.

As shown in fig. 1, a pot 100 according to an embodiment of the present invention includes: outer courage 2, inner bag 1 and heat conduction piece 4.

Specifically, the inner bag 1 is established in outer courage 2 inboardly, inject thermal-insulated chamber 3 between inner bag 1 and the outer courage 2, and thermal-insulated chamber 3 can completely cut off the heat transfer between outer courage 2 and the inner bag 1, avoids outer courage 2's heat transfer to give inner bag 1. The heat conducting block 4 is a good heat conducting object, for example, the heat conducting block 4 may be metal or carbon, the heat conducting block 4 is disposed in the heat insulating chamber 3, and the heat conducting block 4 is convertible between a first state (for example, the state of the heat conducting block 4 shown in fig. 1) and a second state (for example, the state of the heat conducting block 4 shown in fig. 3).

When heat conduction piece 4 is when first state, heat conduction piece 4 links to each other with inner bag 1 and outer courage 2, and heat conduction piece 4 is used for conducting heat between inner bag 1 and outer courage 2, and at this moment, the heat of outer courage 2 can transmit for inner bag 1 through heat conduction piece 4 to realize heating inner bag 1. When heat conduction piece 4 is when the second state, heat conduction piece 4 and at least one separation in inner bag 1 and the outer courage 2, for example, heat conduction piece 4 can only separate with inner bag 1, heat conduction piece 4 also can only separate with outer courage 2, or heat conduction piece 4 and inner bag 1 and outer courage 2 all separate, at this moment, heat conduction piece 4 can not be with outer courage 2 heat transfer to inner bag 1, thereby avoid inner bag 1 temperature-rise too high, ensure that the temperature of inner bag 1 is in suitable culinary art temperature, and then avoid appearing food overburning and lead to nutrition loss or even food scorching etc..

For example, when the pot 100 is in the process of cooking, the outer container 2 can transmit heat to the inner container 1 through the heat conduction block 4, so as to realize rapid heating of the inner container 1 to cook food, and when the temperature of the outer container 2 reaches a certain preset temperature, the heat conduction block 4 is switched from the first state to the second state to cut off the heat transmission between the inner container 1 and the outer container 2, so as to ensure that the temperature of the inner container 1 is always at a certain limited temperature, and further ensure the cooking quality of the pot 100.

According to the cooker 100 provided by the embodiment of the invention, the heat conducting block 4 is arranged, the heat conducting block 4 is switched between the first state of conducting heat between the inner container 1 and the outer container 2 and the second state of not conducting heat between the inner container 1 and the outer container 2, and the first state and the second state of the heat conducting block 4 are switched, so that the cooking temperature of the inner container 1 can be maintained within a limited temperature, the cooking quality of the cooker 100 is improved, and nutrition loss is avoided.

In an embodiment of the present invention, the pot 100 may further include a thermal deformation member 5, the thermal deformation member 5 may be configured to drive the heat conduction block 4 to switch between the first state and the second state, and the thermal deformation member 5 is adapted to drive at least a portion of the outer container 2 away from the inner container 1 when the temperature is higher than a predetermined temperature, so as to switch the heat conduction block 4 to the second state, where the heat conduction block 4 does not conduct heat.

In some embodiments, the predetermined temperature may be in the range of 120 ℃ to 300 ℃, which ensures that the food in the inner container 1 can be cooked normally without scorching. Of course, the range of the predetermined temperature is not limited thereto, the predetermined temperature may be less than 120 ℃ or more than 300 ℃, and the user may set an appropriate predetermined temperature according to the cooking requirement, for example, the predetermined temperature may be 100 ℃, 150 ℃, 200 ℃, 250 ℃, 280 ℃, 320 ℃ or the like.

In some embodiments, the thermal deformation member 5 may include: the heat insulation structure comprises a body part 51 and a heat insulation layer 52, wherein the body part 51 is made of shape memory titanium-nickel alloy; by using the shape memory titanium-nickel alloy as a driving material, the operation procedure of mechanical parts can be simplified, and the execution efficiency of equipment can be improved. However, since the shape memory titanium-nickel alloy is limited by the material properties and the processing process, the martensite transformation starting temperature (Ms) of the titanium-nickel alloy is difficult to break through 100 ℃, therefore, it is preferable that the thermal insulation layer 52 is provided on the outer surface of the main body 51 for thermal insulation to prevent the temperature rise of the shape memory titanium-nickel alloy of the main body 51 from being too high, so as to ensure that the shape memory titanium-nickel alloy of the main body 51 is deformed when the temperature of the outer liner 2 reaches a predetermined temperature, and the outer liner 2 stops heating the inner liner 1 through the heat conduction block 4. The insulating layer 52 may be made of ceramic or insulating material.

Here, it should be noted that the heat insulating effect of the heat insulating layer 52 may be determined according to the set predetermined temperature value, that is, the heat insulating effect of the heat insulating layer 52 may be converted into the actually required predetermined temperature value.

In addition, the body part of the thermal deformation piece of the embodiment of the invention can be in a spring strip shape, so that the deformation amount of the thermal deformation piece can be enhanced, and the sensitivity of the thermal deformation piece for limiting the temperature of the inner pot is further enhanced.

In some embodiments, the heat conducting block 4 can be connected to at most one of the outer container 2 and the inner container 1 in a relatively fixed manner, so that only when the heat conducting block 4 is in the second state, it can be separated from at least one of the inner container 1 and the outer container 2. For example, when the heat conduction block 4 is fixedly connected with the outer container 2, the heat conduction block 4 is separated from the inner container 1 in the second state; when the heat-conducting block 4 is relatively and fixedly connected with the inner container 1, the heat-conducting block 4 is separated from the outer container 2 in the second state.

In some embodiments, the inner container 1 and the outer container 2 may have a shape with an open top, so that the inner container 1 may be conveniently disposed inside the outer container 2, and food may be conveniently cooked in the inner container 1.

Further, the inner container 1 can move up and down relative to the outer container 2, so that the heat conducting block 4 between the inner container 1 and the outer container 2 can be switched between a first heat conducting state and a second non-heat conducting state conveniently. For example, when the diapire activity of inner bag 1 downward orientation outer courage 2, can be convenient for heat conduction piece 4 links to each other with inner bag 1 and outer courage 2 respectively and realizes the heat conduction, when the diapire activity of outer courage 2 is upwards kept away from to inner bag 1, the interval increase between the diapire of inner bag 1 and the diapire of outer courage 2 to be convenient for heat conduction piece 4 to switch into the second state, do not conduct heat.

Advantageously, the upper peripheral edge of the inner container 1 can be hermetically connected with the upper peripheral edge of the outer container 2, and when the heat insulation cavity 3 is a vacuum cavity, the inner container 1 and the outer container 2 are hermetically connected, so that the vacuum degree of the heat insulation cavity 3 can be ensured, and the heat insulation performance of the heat insulation cavity 3 can be ensured.

Specifically, inner bag 1 can include inner bag body 11 and first pot edge 12, the top of inner bag body 11 is opened, first pot edge 12 is established at the last week edge of inner bag body 11, and first pot edge 12 outwards extends, and outer courage 2 can include outer courage body 21 and second pot edge 22, the top of outer courage body 21 is opened, the last week edge at outer courage body 21 is established along 22 to the second pot, and the outside extension of second pot edge 22, wherein, inner bag body 11 is established in the inboard of outer courage body 21, and inner bag body 11 and outer courage body 21 are spaced apart, only can realize the heat transfer through heat conduction piece 4 between inner bag body 11 and the outer courage body 21. .

Further, a second rim 22 is attached to the first rim 12. The first pot edge 12 and the second pot edge 22 are connected in a sealing way along the circumferential direction.

In some embodiments, the thermal insulation chamber 3 may be a vacuum, that is, the thermal insulation chamber 3 is a vacuum chamber, so that thermal insulation between the inner container 1 and the outer container 2 can be achieved (the inner container 1 and the outer container 2 can only transfer heat through the heat conduction block 4). Wherein, when the heat insulation chamber 3 is a vacuum chamber, the vacuum degree of the vacuum chamber is 1.0 × 10^-2Pa to 1.0X 10^-3In the Pa range.

When the inner container 1 and the outer container 2 are made of stainless steel, titanium alloy or copper alloy, the thickness of the inner container 1 and the outer container 2 is not less than 1.5 mm. When the inner container 1 and the outer container 2 are made of aluminum, the thickness of the inner container 1 and the outer container 2 is not less than 2 mm. To prevent deformation of the pot 100.

Of course, in other embodiments, the insulating cavity 3 may be filled with an insulating medium to achieve insulation. The heat insulation cavity 3 has the heat insulation effect and can insulate the heat transfer between the inner container and the outer container.

In some embodiments, the heat conducting block 4 may be a good heat conducting object such as metal or carbon.

The thermal deformation member 5 in the pot 100 of the present invention may be an independent component disposed between the inner container 1 and the outer container 2, the thermal deformation member 5 may also be a thermal deformation member 5 formed by a part of the inner container 1 and/or the outer container 2, the thermal deformation member 5 may also be a heat conduction block 4, etc., the pot 100 in some embodiments of the present invention will be described below with respect to various modes, such as the thermal deformation member 5 being an independent component, the thermal deformation member 5 being a part of the inner container 1 and/or the outer container 2, and the thermal deformation member 5 being a heat conduction block 4, respectively, and the pot 100 may have all or part of the technical features described above.

The first embodiment is as follows: the thermally deformable member 5 being a separate part

As shown in fig. 1 to 4, a pot 100 according to an embodiment of the present invention includes an inner container 1, an outer container 2, a heat conduction block 4, and a thermal deformation member 5, wherein the inner container 1 is disposed inside the outer container 2, a sealed thermal insulation cavity 3 is defined between the inner container 1 and the outer container 2, and the thermal insulation cavity 3 is a vacuum cavity.

Advantageously, the thermally deformable member 5 and the heat-conducting block 4 are both arranged between the bottom wall of the inner container 1 and the bottom wall of the outer container 2. That is, the heat conduction block 4 may be provided between the bottom wall of the inner container 1 and the bottom wall of the outer container 2, and the thermal deformation member 5 may be provided between the bottom wall of the inner container 1 and the bottom wall of the outer container 2. Therefore, the structure of the cooker 100 can be more compact and reasonable.

When the temperature is lower than the preset temperature, the heat conducting block 4 is in a first state, and the heat conducting block 4 is respectively connected with the bottom wall of the inner container 1 and the bottom wall of the outer container 2 so as to realize heat transfer. When the temperature is higher than the predetermined temperature, thermal deformation piece 5 can take place deformation, promotes the diapire of outer courage 2 and keeps away from the diapire of inner bag 1 for heat conduction block 4 is spaced apart with the diapire of inner bag 1 and/or the diapire of outer courage 2, and at this moment, heat conduction block 4 is the second state can not give inner bag 1 with the heat transfer of outer courage 2.

Further, the thermal deformation member 5 may include only one, and certainly, the thermal deformation member 5 may also include a plurality of members arranged along the circumferential direction of the heat conduction block 4, so that when the thermal deformation member 5 drives the outer liner 2 to be away from the inner liner 1, the uniformity of the stress on the outer liner 2 and/or the inner liner 1 may be improved, and the stability of the outer liner 2 and/or the inner liner 1 during the movement process may be enhanced.

Advantageously, the thermal deformation member 5 can be disposed outside the heat conduction block 4, so that the thermal deformation member 5 can be prevented from interfering with the heat conduction block 4, and the structure of the heat conduction block 4 can be simplified, thereby improving the production and processing efficiency.

Alternatively, the thermal deformation member 5 may be relatively fixedly connected with one of the inner bladder 1 and the outer bladder 2. Therefore, the structure of the cooker 100 can be simplified, and the thermal deformation piece 5 can be conveniently installed. When the thermal deformation piece 5 is fixedly connected with the inner container 1 relatively, the thermal deformation piece 5 can drive the inner container 1 to be far away from the outer container 2 when the temperature is higher than the preset temperature; when the thermal deformation piece 5 is fixedly connected with the outer liner 2 relatively, the thermal deformation piece 5 can drive the outer liner 2 to be far away from the inner liner 1 when the temperature is higher than the preset temperature.

Preferably, the thermal deformation member 5 may be configured to elongate 0.5 mm to 2.0 mm when the temperature rises to a predetermined temperature, and thus, at least one of the outer bladder 2 and the inner bladder 1 may be effectively spaced apart from the heat conduction block 4, thereby preventing heat transfer between the outer bladder 2 and the inner bladder 1 such that the temperature of the inner bladder 1 is maintained within a predetermined temperature range.

Advantageously, the inner container 1 can move up and down relative to the outer container 2, and the pot 100 can further include a easily deformable section 6, as shown in fig. 1, the easily deformable section 6 can be an arc-shaped easily deformable section 6. The easy deformation section 6 can link to each other with the last week edge of inner bag 1 and the last week edge of outer courage 2 respectively, can take place deformation when easy deformation section 6, can make the last week edge of inner bag 1 and the last week edge of outer courage 2 link to each other all the time.

Further, the easily-deformable section 6 connects the outer peripheral edge of the first rim 12 and the outer peripheral edge of the second rim 22, so that the inner container 1 and the outer container 2 can be connected into a whole.

According to the pot 100 of the embodiment of the invention, when the temperature does not reach the preset temperature, the deformation memory titanium-nickel alloy does not generate martensite phase transformation, the inner container 1 and the outer container 2 are in close contact with each other through the heat conduction block 4 to conduct heat, when a predetermined temperature (e.g., 150 deg.C, 250 deg.C, 300 deg.C) is reached, the thermally deformable member 5 undergoes a deformation elongation of 0.5 mm to 2 mm, so that the heat-conducting block 4 is separated from the inner container 1, and the arc-shaped easy-deformation section 6 is elastically deformed, because the inner container 1 and the outer container 2 are in vacuum state, when the cooker 100 reaches the designated temperature, the heat of the outer container 2 can not be transferred to the inner container 1, thus, the temperature of the inner container 1 is always ensured to be at a certain limited temperature, but when the temperature of the outer container 2 is reduced, the shape memory alloy recovers the length before phase change, namely, the original state is recovered, and at the moment, the outer container 2 can heat the inner container 1 through the heat conduction block 4.

Example two: the thermal deformation piece 5 is a part of the peripheral wall of the inner container 1 and/or the peripheral wall of the outer container 2

As shown in fig. 5 to 8, the pot 100 according to the embodiment of the present invention includes an inner pot 1, an outer pot 2, and a heat conduction block 4, wherein the inner pot 1 and the outer pot 2 are both in a shape with an open top, an upper peripheral edge of the inner pot 1 is connected to an upper peripheral edge of the outer pot 2, and further, an upper peripheral edge of the inner pot 1 is hermetically connected to an upper peripheral edge of the outer pot 2.

The heat conduction block 4 is arranged between the bottom wall of the inner container 1 and the bottom wall of the outer container 2. Preferably, the heat-conducting block 4 is fixedly connected with at most one of the outer container 2 and the inner container 1.

At least one of the inner container 1 and the outer container 2 comprises an upper container body and a lower container body, that is, only the inner container 1 comprises the upper container body and the lower container body, only the outer container 2 comprises the upper container body and the lower container body, and both the inner container 1 and the outer container 2 comprise the upper container body and the lower container body. And a thermal deformation piece 5 is connected between the upper liner body and the lower liner body.

Specifically, as shown in fig. 7 and 8, when the liner 1 includes the first upper liner body 13 and the first lower liner body 14, the first thermal deformation member 5a may be connected between the first upper liner body 13 and the first lower liner body 14, and the first thermal deformation member 5a is a thermal deformation member that is shortened by heat, that is, when the first thermal deformation member 5a is heated, the first thermal deformation member 5a is shortened.

Preferably, the first thermal deformation member 5a may be configured to be shortened by 0.5 mm to 2.0 mm when the temperature is increased to a predetermined temperature. Thus, when the temperature reaches the predetermined temperature, since the first thermal deformation member 5a is shortened by 0.5 mm to 2.0 mm, the bottom wall of the inner container 1 moves upward by 0.5 mm to 2.0 mm, so that the heat conduction block 4 is separated from at least one of the bottom wall of the inner container 1 and the bottom wall of the outer container 2, and at this time, the heat conduction block 4 is converted into the second state and does not conduct heat. On the contrary, when the temperature is lower than the preset temperature, the first thermal deformation piece 5a recovers deformation, and the heat conduction block 4 is tightly attached to the inner container 1 and the outer container 2 again and conducts heat.

As shown in fig. 5 and 6, when the outer bladder 2 includes the second upper bladder body 23 and the second lower bladder body 24, the second thermal deformation member 5b may be connected between the second upper bladder body 23 and the second lower bladder body 24, and the second thermal deformation member 5b may be a thermal deformation member that is elongated by heat, that is, when the second thermal deformation member 5b is heated, the second thermal deformation member 5b may be elongated.

Preferably, the second thermal deformation member 5b may be configured to elongate by 0.5 mm to 2.0 mm when the temperature is raised to a predetermined temperature. Thus, when the temperature reaches the preset temperature, the bottom wall of the outer container 2 moves downwards by 0.5 mm to 2.0 mm due to the fact that the second thermal deformation piece 5b is heated to extend by 0.5 mm to 2.0 mm, so that the heat conduction block 4 is separated from at least one of the bottom wall of the inner container 1 and the bottom wall of the outer container 2, and the heat conduction block 4 is converted into the second state and does not conduct heat. On the contrary, when the temperature is lower than the preset temperature, the second thermal deformation piece 5b recovers deformation, and the heat conduction block 4 is tightly attached to the inner container 1 and the outer container 2 again and conducts heat.

According to the cooker 100 of the embodiment of the invention, when the outer liner 2 is heated, heat is transferred to the inner liner 1 through the heat conduction block 4 at the bottom, when the temperature of the inner liner 1 (the outer liner 2) reaches a preset temperature, the first thermal deformation piece 5a (the second thermal deformation piece 5b) deforms and shortens (extends), at this time, the inner liner 1 is separated from the heat conduction block 4, the inner liner 1 cannot be well heated, the temperature is reduced, when the temperature is reduced to a certain value, the first thermal deformation piece 5a (the second thermal deformation piece 5b) recovers deformation, at this time, the inner liner 1 is connected with the heat conduction block 4, the inner liner 1 obtains heat again, and the steps are repeated, so that a conditioning object can be maintained at the temperature of a certain curie point.

Example three: the thermal deformation member 5 is a part of the bottom wall of the inner container 1 and/or the bottom wall of the outer container 2

As shown in fig. 9 and 10, in the pot 100 according to the embodiment of the present invention, the heat conduction block 4 is provided between the bottom wall of the inner pot 1 and the bottom wall of the outer pot 2, at least a part of the bottom wall of the outer pot 2 is the thermally deformable member 5 which is elongated by heat, the heat conduction block 4 is provided between the thermally deformable member 5 and the inner pot 1, and further, the heat conduction block 4 is provided on the thermally deformable member 5. The thermally deformable member 5 is adapted to deform in a direction away from the liner 1 (e.g., downward as viewed in fig. 10) when the temperature is above a predetermined temperature.

Advantageously, the hot deformable member 5 is configured to elongate 0.5 mm to 2.0 mm when the temperature is raised to a predetermined temperature.

When the temperature is higher than the preset temperature, the thermal deformation piece 5 deforms and extends downwards by 0.5 mm to 2.0 mm, the thermal deformation piece 5 drives the heat conduction block 4 to move downwards by 0.5 mm to 2.0 mm, so that the heat conduction block 4 is separated from the bottom wall of the liner 1, and the heat conduction block 4 is converted into the second state and does not conduct heat. On the contrary, when the temperature is lower than the preset temperature, the thermal deformation piece 5 recovers the deformation, and the heat conduction block 4 is tightly attached to the inner container 1 and the outer container 2 again and conducts heat.

It should be noted that the shape of the thermal deformation member 5 in the embodiment of the present invention may be any shape when the temperature is lower than the predetermined temperature and higher than the predetermined temperature, as long as the shape can satisfy the requirement that the thermal deformation member 5 supports the heat conduction block 4 when the temperature is lower than the predetermined temperature, so that the heat conduction block 4 is in good contact with the bottom wall of the inner container 1 to realize heat transfer, and when the temperature is higher than the predetermined temperature, the heat conduction block 4 can be separated from the bottom wall of the inner container 1, and heat is not conducted.

Example four: the heat-conducting block 4 is a thermal deformation member 5

As shown in fig. 11 and 12, the pot 100 according to the embodiment of the present invention includes an inner container 1, an outer container 2, and a heat conduction block 4, wherein the heat conduction block 4 is disposed between the bottom wall of the inner container 1 and the bottom wall of the outer container 2, and the heat conduction block 4 is a thermal deformation member. When the heat conduction block 4 is in the first state, the heat conduction block 4 is connected with the bottom wall of the inner container 1 and the bottom wall of the outer container 2 so as to realize heat conduction.

Further, the heat conducting block 4 can be supported on the bottom wall of the outer container 2, and the heat conducting block 4 is separated from the bottom wall of the inner container 1 in the second state and does not conduct heat. Of course, in other embodiments, the heat conduction block 4 may be fixedly connected with the bottom wall of the inner container 1, and the heat conduction block 4 is separated from the bottom wall of the outer container 2 in the second state. That is, it is sufficient if the heat conduction block 4 is separated from at least one of the bottom wall of the inner bag 1 and the bottom wall of the outer bag 2 in the second state.

Advantageously, the heat-conducting block 4 may be one or more. Therefore, the number of the heat conducting blocks 4 can be set according to actual conditions, and the applicability of the pot 100 is improved.

Preferably, the thermally deformable member (the heat conductive block 4) is configured to be shortened by 0.1mm to 2.0 mm when the temperature rises to a predetermined temperature. Further, the thermally deformable member (heat conduction block 4) is configured to be shortened by 0.5 mm to 2.0 mm when the temperature rises to a predetermined temperature. When the temperature is higher than the predetermined temperature, the thermally deformable member (the thermally conductive block 4) deforms.

On the contrary, when the temperature is lower than the preset temperature, the thermal deformation piece (the heat conduction block 4) restores to deform, and the heat conduction block 4 is tightly attached to the inner container 1 and the outer container 2 again and conducts heat.

The thermal deformation assembly is used for driving the heat conduction block 4 to be switched between the first state and the second state, and the thermal deformation assembly is suitable for enabling the heat conduction block 4 to be switched to the second state when the temperature is higher than the preset temperature. That is, when the temperature of the outer container 2 is higher than a predetermined temperature, the thermal deformation assembly drives the heat conduction block 4 to be separated from the inner container 1, and the heat conduction block 4 does not conduct heat.

On the contrary, when the temperature is lower than the preset temperature, the thermal deformation component drives the heat conduction block 4 to contact the inner container 1 again, and the heat conduction block 4 conducts heat between the inner container 1 and the outer container 2 again.

According to the cooker 100 provided by the embodiment of the invention, the heating temperature of the inner container 1 can be limited by switching the heat-conducting block 4 between the first state and the second state, so that the cooking quality is improved.

The cooker 100 of the fifth embodiment further has the following additional technical features.

In some embodiments, the thermal deformation assembly may include: sealing assembly and heat altered shape piece 5, sealing assembly establish in thermal-insulated chamber 3, sealing assembly's lower edge and outer courage 2's internal surface sealing connection, and inject holding tank 8 between sealing assembly and the internal surface of outer courage 2, and holding tank 8's volume is adjustable. The upper edge of the holding tank 8 is not lower than the bottom surface of the liner 1 at any position, that is, the upper edge of the holding tank 8 is completely attached to the bottom surface of the liner 1. When the heat-conducting block 4 is in the first state, the receiving groove has a first volume (e.g., the volume of the receiving groove shown in fig. 13) to accommodate the solid heat-conducting block 4 contacting the outer container 2 and the inner container 1 for heat transfer. When the heat conduction block 4 is in the second state, the accommodating groove has a second volume (for example, the volume of the accommodating groove shown in fig. 14) so as to be suitable for separating the liquid heat conduction block 4 from the liner 1, the heat conduction block 4 does not conduct heat, and the first volume is smaller than the second volume; a thermally deformable member 5 is associated with the sealing assembly, the thermally deformable member 5 being used to vary the volume of the receiving groove 8.

Further, the sealing assembly may include a plurality of sealing blocks 7, the plurality of sealing blocks 7 cooperate with the inner container 1 and the outer container 2 to define a receiving groove 8, the plurality of sealing blocks 7 may include at least one movable sealing block 7 adapted to change a volume of the receiving groove, that is, the plurality of sealing blocks 7 may include only one movable sealing block 7, only one movable sealing block 7 is used to change the volume of the receiving groove 8 by moving, the plurality of sealing blocks may also include two, three, or four or more movable sealing blocks 7, and the volume of the receiving groove 8 can be changed by moving two, three, four or more movable sealing blocks 7. The thermal deformation member 5 may be connected to the movable sealing block 7, and the thermal deformation member 5 is used to drive the movable sealing block 7 to move to change the volume of the receiving groove 8.

Referring to fig. 13 and 14, when the heat conducting block 4 is in the first state, the heat conducting block 4 is solid, and the heat conducting block 4 completely fills the first volume of the accommodating groove 8, and the heat conducting block 4 is in contact with the inner container 1 and the outer container 2 respectively to realize heat transfer. When the temperature reaches the predetermined temperature, heat conduction piece 4 melts to liquid, because the second volume that holds liquid heat conduction piece 4 is greater than the first volume that holds solid-state heat conduction piece 4, consequently, liquid heat conduction piece 4 can not be full of the holding tank that has the second volume completely, and like this, liquid heat conduction piece 4 then can not contact with the diapire of inner bag 1, can not realize heat transfer.

Advantageously, as shown in fig. 13, the sealing assembly may comprise two sealing blocks 7, the two sealing blocks 7 being arranged opposite each other, and the two sealing blocks 7 being movable in a direction towards each other (for example in a direction towards the central axis of the inner and outer liners 1, 2) and away from each other (for example in a direction radially outwards of the inner or outer liners 1, 2), the thermo-deformable member 5 being associated with at least one sealing block 7, that is to say the thermo-deformable member 5 may be associated with only one sealing block 7, and the thermo-deformable member 5 may also be associated with two sealing blocks 7. When the thermal deformation member 5 deforms, the thermal deformation member 5 can drive the sealing blocks 7 to move closer to or away from each other, thereby switching the accommodation groove 8 between the first volume and the second volume.

Further, in some embodiments, the thermal deformation member 5 may be provided between the two sealing blocks 7, the thermal deformation member 5 may be connected to the two sealing blocks 7, respectively, and the thermal deformation member 5 is configured to push the two sealing blocks 7 away from each other when the temperature is higher than a predetermined temperature. That is to say, when the temperature is higher than the predetermined temperature, heat conduction block 4 melts from solid to liquid, and simultaneously, thermal deformation piece 5 takes place to warp, promotes two sealed pieces 7 and keeps away from each other for holding tank 8 increases to the second volume from first volume, and liquid heat conduction block 4 separates with the inner bag, does not conduct heat.

Preferably, the thermally deformable member 5 may be configured to elongate not less than 0.1mm when the temperature is raised to a predetermined temperature, in other words, the thermally deformable member 5 elongate at least 0.1mm when the temperature is raised to a predetermined temperature, whereby the thermally deformable member 5 may push the two seal blocks 7 away from each other by at least 0.1mm, thereby increasing the first volume of the accommodation groove 8 to the second volume.

In other embodiments, the thermal deformation member 5 may also be disposed outside the two sealing blocks 7, one end of the thermal deformation member 5 is connected to the sealing block 7, and the other end of the thermal deformation member 5 is connected to the outer bladder 2 or the inner bladder 1, and the thermal deformation member 5 may be configured to pull the two sealing blocks 7 away from each other when the temperature is higher than a predetermined temperature. Further, the thermally deformable member 5 may be configured to shorten by not less than 0.1mm when the temperature rises to a predetermined temperature.

Specifically, when the temperature rises to predetermined temperature, heat conduction piece 4 melts from solid state to liquid, and thermal deformation piece 5 takes place the deformation simultaneously, shortens at least 0.1 millimeter, and at this moment, thermal deformation piece 5 can pull two sealing members and keep away from each other at least 0.2 millimeter to make the holding tank have the bigger second volume of volume, make liquid heat conduction piece 4 and inner bag 1 separation, do not conduct heat.

In some embodiments, a plurality of sealing blocks 7 may be disposed between the bottom wall of the inner container 1 and the bottom wall of the outer container 2, and a flexible section (not shown) is connected between the plurality of sealing blocks 7. When 5 pulling at least one sealed piece 7 of thermal deformation spare remove, deformation can take place for yielding to guarantee that a plurality of sealed pieces 7 link to each other all the time, from this, a plurality of sealed pieces 7 can inject the holding tank of volume adjustable jointly with inner bag 1 and outer courage 2, break with avoiding between sealed piece 7 and the sealed piece 7, or avoid can not resume deformation between sealed piece 7 and the sealed piece 7, avoid liquid heat conduction piece 4 to leak.

In some embodiments, the spacing between the two sealing blocks 7 when the thermal conduction block 4 is in the first state is at least 0.1mm less than the spacing between the two sealing blocks 7 when the thermal conduction block 4 is in the second state. Therefore, when the heat conduction block 4 is switched from the first state to the second state and the solid state is melted into liquid state, the heat conduction block 4 and the inner container 1 are effectively spaced, and heat is not conducted between the heat conduction block 4 and the inner container 1.

Alternatively, the thermally deformable member may include one or more.

Since the heat conductive block 4 changes from a solid to a liquid when the heat conductive block 4 is switched from the first state to the second state, however, the predetermined temperature of the embodiment of the present invention is in the range of 120 ℃ to 300 ℃, it is preferable that the heat conductive block 4 is a low melting point heat conductive block 4, and specifically, the heat conductive block 4 may be a heat conductive block 4 having a melting point between 120 ℃ and 300 ℃. The heat-conducting block 4 may be, for example, a heat-conducting metal block of low melting point.

before the shape memory titanium-nickel alloy spring does not generate martensite phase transformation, the inner container 1, the outer container 2 and the heat conducting block 4 are in close contact for heat transfer. Wherein, the contact part is composed of three parts: a low-melting-point metal heat conducting block 4, a sealing block 7 and a shape memory titanium-nickel alloy (a thermal deformation piece 5). Wherein, at any set temperature of 120-300 ℃, the shape of the shape memory titanium-nickel alloy spring can deform and contract, and the sealing block 7 is pulled to move towards the side wall of the pot, so that the sealing space is enlarged, the low-melting-point metal heat conducting block 4 is separated from the bottom of the inner container after being melted, and the separation distance is more than 0.1 mm; the distance between the inner container and the outer container is 2-10mm, when the temperature is reduced, the diameter of the semicircular heat conducting block returns to the original shape, the semicircular sealing block 7 is pushed to return to the original state, and the heat conducting low-melting-point metal is re-solidified into a block which is in good contact with the bottom of the inner container, so that a good heat conducting effect is generated.
