Description

Technical Field

[0001] This disclosure relates to the field of thermal insulation container technology, and in particular to a mechanically thermally controllable thermal insulation container and its lid. Background Technology

[0002] Currently, traditional insulated containers typically rely on hollow layers, vacuum layers, or insulation layers to block the heat transfer path (referred to as the "thermal path"), thereby prolonging the time it takes for the contents to approach the ambient temperature and thus achieving an insulation effect. However, this type of passive insulation structure has significant limitations. When users need to reduce or decrease the insulation efficiency and increase the rate of heat exchange between the inside and outside of the insulated container to allow the contents to reach a suitable temperature in a timely manner, they often have to rely on natural cooling, which is time-consuming. If the container lid is directly opened to accelerate the heat exchange between the inside and outside of the insulated container, it can easily lead to leakage or contamination of the contents.

[0003] To address this issue, invention patent application number 202122249467.8 discloses a thermos cup with rapid cooling. This solution incorporates spiral guide vanes within the temperature control zone between the inner and outer containers and utilizes an external blower for forced convection cooling. While this solution achieves rapid cooling, it requires an internal power supply and electrical components (such as a motor and fan), resulting in a complex structure, increased sealing difficulty, high cost, and a high failure rate.

[0004] In addition, invention patent application number 201420422854.4 discloses a rapid cooling cup, which uses liquid metal as a heat-conducting medium by filling a container made of double-layered glass. Although it utilizes the high heat absorption and thermal conductivity of liquid metal, it requires a separate sealed container to hold the liquid metal, which not only increases the weight of the container but also occupies the effective volume. Furthermore, the sealing safety requirements for the liquid metal are extremely high.

[0005] Therefore, there is an urgent need for a thermal insulation container that is simple in structure, requires no external power supply, is highly reliable, and can effectively control the thermal insulation performance. Summary of the Invention

[0006] The purpose of this disclosure is to provide a mechanically thermally controllable insulated container and its lid, which solves the problems of existing insulated containers that, without opening the lid, cannot quickly cool or heat the contents as needed and maintain the temperature after reaching the appropriate temperature, and that opening the lid can easily lead to spillage and contamination of the contents when the internal and external heat exchange is accelerated.

[0007] To achieve the above objectives, this solution proposes a mechanically controllable thermal insulation container and its lid, comprising an outer shell and an inner liner, wherein at least one mechanically controllable thermal path is constructed between the inner liner and the outer shell, the mechanically controllable thermal path comprising: A thermally conductive communication mechanism includes a mechanical resistance switch disposed between the inner liner and the outer shell, so as to form a thermal path connecting the inner liner and the outer shell through the mechanical resistance switch, wherein the change in thermal resistance of the thermal path is controlled by the mechanical resistance switch; A control mechanism, located on the outer shell, is used to regulate the heat exchange rate between the inside and outside of the insulation container by manipulating the change in the thermal resistance value of the mechanical resistance switch, thereby switching the insulation state of the insulation container.

[0008] Furthermore, the control mechanism employs a mechanical transmission structure to control the opening and closing of the thermal circuit and the change in thermal resistance; A control mechanism is provided on the heat-conducting outer shell to control the closing and opening of the contacts and the change of the contact area. By driving the active contact to move, the active contact is connected to the passive contact and the contact area is changed, thereby controlling the opening and closing of the thermal path and the change of the thermal resistance.

[0009] Furthermore, the mechanical resistance switch is a ferromagnetic reed structure; The control mechanism includes a movable permanent magnet component disposed outside the outer shell. When the permanent magnet component moves to a position corresponding to the suspended end of the ferromagnetic tongue reed corresponding to the outer shell, it controls the opening and closing of the controllable thermal circuit. The controllable thermal path controlled by the permanent magnet component can be configured as multiple paths, and multiple permanent magnet components can be configured accordingly.

[0010] Furthermore, the heat-conducting communication mechanism adopts a ferromagnetic tongue spring matching and embedded combined support frame structure, and prefabricated a single independent support frame with a ferromagnetic tongue spring. The single independent support frame can be matched and embedded in the space between the outer shell and the inner liner. The single independent support frame can be composed of multiple arrays; a movable control mechanism is provided on the outside of the outer shell corresponding to the position of the ferromagnetic tongue reed, and the control mechanism can drive the permanent magnet component to approach or move away from the ferromagnetic tongue reed to control the opening and closing of the thermal circuit.

[0011] Furthermore, the prefabricated support frame with ferromagnetic tongue reeds consists of a thermal circuit switch array support frame module composed of multiple ferromagnetic tongue reeds; after the switch array support frame module is matched and embedded in the space between the inner liner and the outer shell, it together with the control mechanism with matching and distributed permanent magnet components to form a magnetic mechanical controllable thermal circuit between the inner liner and the outer shell.

[0012] Furthermore, the controllable mechanical thermal circuit is equipped with a temperature control switch device and a controllable component for adjusting the contact spacing, thereby constructing a temperature-controlled controllable mechanical thermal circuit. The contact spacing is adjusted by the controllable component to set the temperature for the thermal circuit to be on or off.

[0013] Furthermore, the mechanically controllable thermal circuit includes an insulation component, an insulation sealing plate, and a control mechanism; the insulation component with through holes is disposed between the inner liner and the outer shell, and the opening of the insulation sealing plate covering the through holes can be adjusted by manipulating the control and transmission components, thereby regulating the flow rate of the through holes of the insulation component and changing the heat exchange efficiency of the channel-type thermal circuit.

[0014] Furthermore, a magnetic transmission structure can be adopted, such as permanent magnet component-permanent magnet component or permanent magnet component-ferromagnetic component, to drive the control mechanism components inside and outside the shell to move synchronously with magnetic force.

[0015] Furthermore, the ferromagnetic tongue reed can also be constructed by mounting a permanent magnet component on the suspended end of a non-ferromagnetic ordinary tongue reed.

[0016] Furthermore, when the inner liner or outer shell of the insulated container or its lid is made of high thermal resistance materials such as glass or plastic, a thermal path can be constructed by adding heat-conducting fins and heat dissipation windows.

[0017] Furthermore, a thermometer is installed on the insulated container or its lid to display the temperature of the contents.

[0018] Taking hot beverages as an example of the contents of an insulated container: By adopting the above technical solution, a controllable thermal path is formed by a heat-conducting connection structure and a control structure between the outer shell and the inner liner of the insulated container. When rapid heat dissipation of hot beverages or hot water inside the insulated container is required, the control structure can control the heat-conducting connection structure to connect the inner liner and the outer shell, thus forming a thermal path between them. This allows heat dissipated onto the inner liner to be dissipated to the outer shell through the heat-conducting connection structure and exchanged with the outside environment, enabling rapid heat exchange between the hot beverage inside the inner liner and the outside environment, achieving a rapid cooling effect. Simultaneously, after the temperature of the hot beverage drops to a specified temperature, the control structure can relatively disconnect the heat-conducting connection structure, thus relatively breaking the thermal path and preventing heat exchange through this path, thereby continuing to keep the contents of the container warm. This allows for rapid cooling of hot water in the insulated container, such as while driving, avoiding spillage, and offers high heat dissipation efficiency, quickly bringing the hot beverage in the insulated container to the user's desired temperature, thus meeting more user needs.

[0019] Furthermore, the products based on the above-mentioned technical solutions can also regulate the rate at which the temperature of contents such as food and medicine rises and falls by controlling the heat exchange inside and outside the insulated container.

[0020] Other features and advantages of this disclosure will be further described in the following detailed description section. Attached Figure Description

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure. Example 1

[0025] This disclosure provides a mechanically thermally controllable insulated container and its lid, such as... Figure 1-3 As shown, the aforementioned mechanically controlled thermal insulated container and its lid include an outer shell 1 and an inner liner 2. At least one mechanically controlled thermal path is constructed between the outer shell 1 and the inner liner 2 to regulate the heat exchange efficiency between them, thereby altering the rate of temperature rise and fall of the contents. This mechanically controlled thermal path includes a thermally conductive connection structure 4 and a control structure. The thermally conductive connection structure 4 is disposed between the inner liner 2 and the outer shell 1. This thermally conductive connection structure 4, through a mechanical resistance switch, forms a controllable thermal path connecting the inner liner 2 and the outer shell 1. The change in the thermal resistance of this thermal path is controlled by the mechanical resistance switch.

[0026] The control structure is located on the outer shell 1 and is used to control the change of thermal resistance value of the thermal circuit by operating the mechanical resistance switch, thereby regulating the heat exchange rate inside and outside the insulation container and switching the insulation state of the insulation container.

[0027] The controllable thermal path formed by the thermally conductive connection structure 4 and the control structure allows for rapid heating or cooling of hot drinks or other contents within the insulated container. The control structure connects the inner liner 2 and the outer shell 1, creating a thermal path that accelerates heat exchange between the contents of the inner liner 2 and the external environment. Conversely, once the contents reach the desired temperature, the control mechanism disconnects the thermally conductive connection structure 4 and the thermal path, preventing heat exchange and allowing the insulated container to resume its insulation state. This enables manual switching of the insulated container's insulation status.

[0028] The aforementioned control mechanism uses a mechanical transmission structure to control the opening and closing of the thermal circuit and the change of thermal resistance. A control mechanism is provided on the heat-conducting shell 1 to control the closing and opening of the contacts and the change of the contact area. By driving the active contact to move, the active contact and the passive contact are connected or disconnected, and the contact area changes, thereby controlling the opening and closing of the thermal circuit and the change of the thermal circuit resistance.

[0029] like Figure 3 As shown, a mechanically controlled thermal insulation container and its container lid 3 include an upper cover plate 31, an inner heat-conducting plate 32 and an outer heat-conducting plate 34. The outer heat-conducting plate 34 is movably connected to the upper cover plate 31, which serves as a fixing frame, and multiple active contact plates 35 are spaced apart on the edge of the outer heat-conducting plate 34. The inner heat-conducting plate 32 is connected to the outer wall of the inner liner 2, or the inner heat-conducting plate 32 is integrated with the inner liner 2, and multiple passive contact plates 33 are spaced apart on the edge of the inner heat-conducting plate 32. Additionally, a rotating shaft 36 is rotatably mounted on the upper cover plate 31. One end of the rotating shaft 36 passes through the upper cover plate 31 and is connected to the outer heat-conducting plate 34 to drive the outer heat-conducting plate 34 to rotate, thereby making each active contact piece 35 contact and each passive contact piece 33, or changing the contact area between them, to form a controllable heat-conducting communication mechanism, i.e., a mechanically controllable heat circuit. The upper cover plate 31 has one or more through holes, or directly adopts a fixing frame structure with through holes, to facilitate heat exchange between the outer heat-conducting plate 34 and the outside. The position, shape, and gap of each passive contact piece 33 and each active contact piece 35 are matched.

[0030] By providing the aforementioned structure on the container lid 3, when the container lid 3 is installed on the insulated container, and when it is necessary to accelerate the heat exchange between the contents inside the insulated container and the outside environment, the outer heat-conducting plate 34 can be rotated relative to the rotating shaft 36. This causes each active contact plate 35 and each passive contact plate 33 to come into contact, and the contact area is adjusted to change the thermal resistance value of the thermal path. This allows the contents to change the rate of heat exchange with the outside environment through the inner liner 2, the inner heat-conducting plate 32, and the outer heat-conducting plate 34, so that the contents reach a suitable temperature within a set time. Correspondingly, when heat preservation is required, the outer heat-conducting plate 34 can be driven to rotate in the opposite direction, causing the contact area between the active contact plate 35 and the passive contact plate 33 to decrease or relatively separate, increasing the thermal resistance of the heat dissipation path until it is disconnected, thereby achieving the heat preservation effect.

[0031] In terms of control and transmission, this technical solution can also be implemented by using other mechanical on / off switches, mechanical resistance switches, and other direct mechanical transmission methods to control the on / off state of the active and passive contacts, as well as adjust the contact area, control the on / off state of the thermal circuit, and control resistance changes, thereby constructing a controllable heat-conducting connection mechanism; or by adding permanent magnet component-permanent magnet component, permanent magnet component-ferromagnetic block magnetic control mechanism inside and outside the shell, and using magnetic force to control the action of the mechanical resistance switch; this technical solution is not limited to the container lid, but can also be applied to the body of the insulated container.

[0032] like Figure 12 As shown, the mechanically controllable thermal circuit can also construct a controllable thermal circuit between the inner liner and the outer shell through the insulation component 71 with through holes, the insulation sealing plate 73, and the control mechanism. By controlling the transmission component, the opening of the through hole covered by the insulation sealing plate 71 can be adjusted, the flow rate of the through hole of the insulation component 71 can be regulated, and the heat exchange efficiency of the channel-type thermal circuit can be changed.

[0033] The insulated container and its lid disclosed herein can be in the shape of a box, can, etc., and can be made into a water cup, lunch box, insulated box, etc., and can be used for keeping cold or hot, and are not limited herein. Example 2

[0034] like Figure 1 and Figure 2 As shown, the control mechanism uses a mechanical transmission structure to control the opening and closing of the thermal circuit and the change of thermal resistance. A control mechanism is provided on the outer casing 1 to control the closing and opening of the contacts and the change of the contact area. By driving the active contact to move, the active contact is connected and disconnected from the passive contact, thereby controlling the opening and closing of the thermal circuit.

[0035] like Figure 1 and Figure 2As shown, the aforementioned mechanical resistance switch is a ferromagnetic reed structure. The control mechanism includes a movable permanent magnet component disposed outside the housing 1. When the permanent magnet component moves to the position corresponding to the suspended end of the ferromagnetic reed corresponding to the housing 1, it controls the opening and closing of the controllable thermal circuit. The controllable thermal circuit controlled by the permanent magnet component can be configured as multiple circuits, and multiple permanent magnet components are correspondingly provided.

[0036] Among them, such as Figure 1 and Figure 2 As shown, the thermal conductive connection mechanism 4 includes a first ferromagnetic tongue spring 41, which is disposed at the bottom of the inner liner 2. One end of the first ferromagnetic tongue spring 41 is connected to the inner liner 2, and the other end faces the outer shell 1 and is suspended. The permanent magnet component can be a first permanent magnet component 42, which is movably disposed at the bottom of the outer shell 1. When the first permanent magnet component 42 moves to the outer shell 1 corresponding to the suspended end of the first ferromagnetic tongue spring 41, the suspended end of the first ferromagnetic tongue spring 41 shifts and abuts against the outer shell 1.

[0037] By utilizing the first ferromagnetic reed 41 and the first permanent magnet component 42, when it is necessary to open the thermal path to accelerate heat exchange between the inside and outside of the container, the position of the first permanent magnet component 42 can be moved relative to the position of the relatively suspended end of the first ferromagnetic reed 41. Due to the attraction of the first permanent magnet component 42, the first ferromagnetic reed 41 can be bent relative to it, causing its suspended end to abut against the bottom of the outer shell 1, thereby achieving thermal path connection between the inner liner 2 and the outer shell 1 and accelerating heat exchange between the inside and outside of the insulated container. When heat preservation is required, the first permanent magnet component 42 can be moved back to its original position. At this time, the first ferromagnetic reed 41 will not be attracted by the magnet and will return to its original state, thus disconnecting the thermal path between the inner liner 2 and the outer shell 1 and achieving heat preservation.

[0038] The first permanent magnet component 42 is slidably disposed at the bottom of the outer shell 1. Specifically, a horizontally movable guide rail 43 can be fixedly disposed at the bottom of the outer shell 1, with one end of the guide rail 43 corresponding to the position of the suspended end of the first ferromagnetic tongue reed 41. Then, the first permanent magnet component 42 is configured as a slider adapted to the guide rail 43, so that the first permanent magnet component 42 is directly slidably disposed on the guide rail 43. In this way, when the first permanent magnet component 42 is slid to the end of the guide rail 43 corresponding to the suspended end of the first ferromagnetic tongue reed 41, the thermal circuit can be made conductive. When it is moved to a position away from the suspended end of the first ferromagnetic tongue reed 41, the thermal circuit is disconnected accordingly.

[0039] Furthermore, limiting iron blocks can be respectively set at both ends of the guide rail 43, so that after the iron blocks move to both ends of the guide rail 43, the first permanent magnet component 42 can be relatively fixed so that it will not be displaced, thus avoiding the first permanent magnet component 42 from shifting due to vibration or other reasons, so that the thermal circuit is not controlled according to the user's needs.

[0040] It should be noted that other structures can also be provided at both ends of the guide rail 43 to limit the position of the first permanent magnet component 42, such as Velcro for limiting and fixing at both ends of the first permanent magnet component 42 and the guide rail 43, or a snap-fit ​​structure for limiting. This disclosure does not limit the structure for regulating its movement stroke. This technical solution is not limited to normally open switch thermal circuits, but also includes normally closed switch thermal circuits. For example, one end of the first ferromagnetic tongue reed 41 is fixedly thermally connected to the bottom of the outer shell 1, and its suspended end is thermally connected to the outer wall of the inner liner 2, so that the thermal circuit is open. When the first permanent magnet component 42 approaches the first ferromagnetic tongue reed 41, under the action of magnetic force, the suspended end of the first ferromagnetic tongue reed 41 disengages from the outer wall of the inner liner 2, and the thermal circuit is broken. The controllable thermal circuit controlled by the permanent magnet component can be set to multiple circuits, and multiple permanent magnet components are set accordingly.

[0041] It should also be noted that the permanent magnet component refers to a component made of permanent magnet material that can generate magnetic force, and its shape is not limited; the ferromagnetic tongue reed refers to a component made of ferromagnetic material that can generate magnetic force with the permanent magnet component and has elasticity, as well as a component with a permanent magnet component at its suspended end and having elasticity; the route of the first permanent magnet component 42 approaching the first ferromagnetic tongue reed 41 can take various forms and is not limited. For ease of assembly, the ferromagnetic tongue reed can also be prefabricated into a heat-conducting communication mechanism component by combining it with a positioning and fixing frame and a support frame that fits the bottom space of the cup, which facilitates positioning and installation and enhances load-bearing and pressure resistance; this solution can also be applied to other parts of the insulated container and its lid, or multiple thermally controllable heat-conducting communication mechanisms can be constructed, using multi-thermal-path control.

[0042] Alternatively, the aforementioned ferromagnetic reed structure can also be constructed by mounting a permanent magnet component on the suspended end of a non-ferromagnetic ordinary reed. This structure can also achieve the aforementioned heat conduction function, thus enabling the opening and closing of the thermal path. Example 3

[0043] like Figure 4As shown, the heat-conducting communication mechanism includes a second ferromagnetic reed 51 and corresponding heat-conducting and fixing components. One end of the second ferromagnetic reed 51 is connected to the outer wall of the inner liner 2, and the other end is suspended and facing the inner wall of the outer shell 1, without contacting the inner wall of the outer shell 1, forming a normally open heat path; or one end of the second ferromagnetic reed 51 is thermally connected to the inner wall of the outer shell 1, and the other suspended end is thermally connected to the outer wall of the inner liner 2, thus conducting the heat path and forming a normally closed heat path. The control mechanism includes a second permanent magnet component 52 disposed on the outer wall of the outer shell 1. The second permanent magnet component 52 is movably disposed on the outer wall of the outer shell 1. When the permanent magnet component 52 moves to the position where the end of the ferromagnetic reed 51 corresponds to the position of the outer shell 1, the end of the second ferromagnetic reed 51 abuts against the inner wall of the outer shell 1, and the normally open heat path is opened; similarly, the normally closed heat path is opened, thus realizing the switching of the heat path being open and closed.

[0044] By utilizing the second ferromagnetic tongue reed 51 and the second permanent magnet component 52, the speed of heat exchange between the contents and the outside can be adjusted by moving the second permanent magnet component 52 relative to the position of the suspended end of the second ferromagnetic tongue reed 51, thereby achieving the switching of the heat preservation state.

[0045] Furthermore, such as Figure 4 and Figure 5 as well as Figure 13 As shown, a movable annular control structure 53 is provided on the outer wall of the outer shell 1, and the second permanent magnet component 52 is fixedly disposed on the annular control structure 53.

[0046] The technical solution of using the circular control structure 53 can fix the second permanent magnet component 52. At the same time, by controlling the movement of the circular control structure 53, the movement of the second permanent magnet component 52 can be controlled, so that the second permanent magnet component 52 can move closer to or further away from the suspended end of the second ferromagnetic tongue reed 51.

[0047] The first permanent magnet component 42 and the second permanent magnet component 52 mentioned above can be made of magnet blocks or other magnetic structures, and this disclosure does not limit them. Example 4

[0048] Combination Figure 5 and Figure 6 As shown, the above-mentioned heat conduction communication mechanism adopts a ferromagnetic tongue spring matching and embedded combined support frame structure. It is prefabricated as a single independent support frame with a ferromagnetic tongue spring. The single independent support frame can be matched and embedded in the space between the outer shell and the inner liner. Multiple single independent support frames can be arranged in an array. A movable control mechanism with a permanent magnet component is provided on the outside of the outer shell corresponding to the position of the ferromagnetic tongue spring. The control mechanism can control the opening and closing of the heat path by driving the permanent magnet component to approach or move away from the ferromagnetic tongue spring.

[0049] An independent support frame device is fabricated by matching and embedding ferromagnetic tongue reeds, forming a modular heat-conducting and connecting mechanism. Figure 6 An independent support frame for a normally open thermal circuit switch with a ferromagnetic reed is provided. When the permanent magnet component is far away from the ferromagnetic reed 51, the thermal circuit remains open. The transverse support rod or plate 543 is made of thermal insulation material. Figure 7 An independent support frame for a normally closed thermal circuit switch with a ferromagnetic reed is provided. When the permanent magnet component is far away from the ferromagnetic reed 51, the thermal circuit remains closed. The transverse support rod or plate 543 is made of thermal insulation material. Figure 8 This is a schematic diagram of a prefabricated circular support structure for embedding and installing within the insulation layer of an insulated container; such as... Figure 6-8 As shown, the support frame is composed of multiple radial support rods 543, axial support rods 544, inner ring plates 541, and outer ring plates 542. Its characteristic is that after being installed between the outer shell and the inner liner, it ensures that the support frame body is thermally insulated. The opening and closing of the thermal circuit is completely controlled by the action of the ferromagnetic tongue spring. The shape and size of the support frame fit the space between the inner liner 2 and the outer shell 1, and can be fitted and installed in the space between the inner liner 2 and the outer shell 1, so as to play a stable supporting role for the overall structure.

[0050] like Figure 6-8 As shown, to ensure a firm connection and reliable thermal circuit, inner ring plates 541 and outer ring plates 542 can be made of low thermal resistance thermally conductive materials at the contact surfaces of the support frame with the outer shell 1 and the inner liner 2, respectively, forming a controllable thermal circuit thermal connection mechanism. During assembly, the thermally conductive inner ring plates 541 and outer ring plates 542 of the 1-N support frames are thermally connected to the inner liner 2 and the outer shell 1, respectively, so that the support frame provides stable support while constructing one or more controllable thermal circuits. A movable control mechanism with a permanent magnet component is provided on the outside of the outer shell 1 corresponding to the position of the ferromagnetic tongue reed. The control mechanism with the permanent magnet component drives the permanent magnet component to approach or move away from the ferromagnetic tongue reed, controlling the opening and closing of the thermal circuit. As needed, slots, protrusions, and other structures can be provided on the outer shell 1 and the inner liner 2 to facilitate the positioning and fixing of the support frame. A modular manufacturing method using prefabricated independent support frames with ferromagnetic tongue reeds is adopted to prepare independent controllable thermal conduction and connection mechanism components, which is beneficial to the standardization and quality control of workpieces and also facilitates assembly and production.

[0051] Thus, the inner ring plate 541 is fixedly connected to the inner wall of the inner liner 2, and the outer ring plate 542 is fixedly connected to the inner wall of the outer shell 1. Multiple radial support rods 543 are provided, evenly distributed circumferentially between the inner ring plate 541 and the outer ring plate 542. One end of the aforementioned ferromagnetic tongue spring 51 is fixed to the heat-conducting inner ring plate 541. This ensures the stability between the inner liner and the outer shell. The radial support rod 543 is made of a high thermal resistance material. Example 5

[0052] like Figure 4 and Figure 5 As shown, the prefabricated support frame with magnetically controlled switches consists of a second ferromagnetic reed 51, an inner ring 541, an outer ring 542, a radial support rod 543, and an axial support rod 544, forming a ring-shaped support frame heat-conducting communication mechanism. The radial support rod 543 is made of a high thermal resistance material, while the inner ring 541, outer ring 542, and axial support rod 544 can be made of a low thermal resistance material. Multiple normally open or normally closed thermal circuit switches composed of ferromagnetic reeds 51 are matched and embedded to form a thermal circuit switch array support frame type heat-conducting communication mechanism module. After the ring-shaped support frame type heat-conducting communication mechanism module is matched and embedded in the space between the inner liner and the outer shell, it, together with the control mechanism with permanently magnet components distributed outside the outer shell, forms a magnetomechanical controllable thermal circuit between the inner liner and the outer shell. Additional inner and outer heat-conducting sheets can be added as needed. The magnetically controlled switch support frame type heat conduction and connection mechanism module with multiple ferromagnetic reeds can also be made into various shapes such as square and strip as needed to form a thermal circuit magnetically controlled switch array module, which together with the corresponding fixed embedded permanent magnet component control mechanism forms a multi-path magnetic mechanical controllable thermal circuit.

[0053] The controllable thermal circuit of the annular control structure 53 equipped with permanent magnet components can also adopt other schemes for controlling the opening and closing actions of ferromagnetic reeds in terms of its movement mode and structural design. In this embodiment, combined with Figure 9 As shown, an annular protrusion 531 can be provided on the outer wall of the outer shell 1. Correspondingly, an annular groove 532 is provided on the side of the annular control structure 53 that fits into the outer shell 1, so that the annular protrusion 531 and the groove 532 cooperate with each other. In this way, the rotation of the annular control structure 53 on the outer shell 1 can be realized.

[0054] By utilizing the arrangement of multiple ferromagnetic reeds 51, in heat exchange control, each ferromagnetic reed 51 can be controlled to synchronously contact or move away from the inner wall of the outer shell 1, thereby constructing multiple controllable heat paths between the inner liner 2 and the outer shell 1 through multiple heat-conducting communication mechanisms, which can improve the efficiency of heat exchange.

[0055] It should be noted that a limiting structure can be provided between the aforementioned annular control structure 53 and the outer casing 1 to limit the arbitrary rotation of the annular control structure 53 and to limit the position of the annular control structure 53 after rotating to a certain position. For example, a vertically sliding stop bar can be provided on the outer casing 1. Correspondingly, two locking holes are provided at intervals on the upper end face of the annular control mechanism 53. When the annular control mechanism 53 rotates so that the permanent magnet component 52 is positioned corresponding to the suspended end of the ferromagnetic tongue reed 51, moving the stop bar downwards allows it to be inserted into one of the locking holes. When the permanent magnet component 52 is moved away from the suspended end of the ferromagnetic tongue reed 51, moving the stop bar downwards allows it to be inserted into the other locking hole. This effectively limits the position of the annular control structure 53, preventing the annular control structure 53 from rotating or shifting due to vibration or other reasons. Example 6

[0056] A temperature-controlled switch device and a regulating component for adjusting the contact spacing are provided on the controllable mechanical thermal circuit. The temperature-controlled mechanical controllable thermal circuit is constructed by a temperature-controlled heat-conducting connection mechanism. The contact spacing is adjusted by the regulating component to set the temperature for the thermal circuit to be on or off.

[0057] like Figure 10 As shown, taking the construction of a temperature-controlled mechanical controllable thermal circuit in a container lid as an example, the container lid 3 includes an inner heat-conducting sheet 61 and an outer upper plate 62. A heat-insulating space 63 is formed between the inner heat-conducting sheet 61 and the outer upper plate 62 of the container lid 3. A temperature-controlled switch device 64 is installed in the heat-insulating space 63. The temperature-controlled switch device 64 is thermally connected to the inner heat-conducting sheet 61, forming a heat-conducting communication mechanism. The temperature-controlled switch device 64 can deform according to temperature changes. The inner heat-conducting sheet 61 can be directly composed of a heat-conducting inner liner, or it can be composed of an inner liner and a heat-conducting sheet. The outer upper plate 62 can be directly composed of a heat-conducting outer shell, or it can be composed of a heat-conducting outer shell and an upper plate with heat dissipation holes.

[0058] A heat-conducting connecting member 65 with contacts is provided on the upper end plate 62 of the container lid 3 at the position corresponding to the temperature control switch device 64. The heat-conducting connecting member 65 is provided corresponding to the temperature control switch device 64. When the temperature control switch device 64 expands and deforms as the temperature rises, the temperature control switch device 64 comes into contact with the heat-conducting connecting member 65.

[0059] With the above-described structure, the temperature for switching the insulation performance of the insulation container can be set by adjusting the position of the heat-conducting connecting member 65. Specifically, the temperature control device 64 deforms with temperature changes, thereby changing the position of the heat-conducting connecting member 65 relative to the temperature control switch device 64. When the temperature drops to the corresponding temperature, the temperature control switch device 64 can contract as the temperature decreases, so that the temperature control switch device 64 does not come into contact with the heat-conducting connecting member 65, thus breaking the thermal path and preventing further heat transfer. When the temperature is higher than the corresponding temperature, the temperature control switch device 64 extends, so that the temperature control device 64 continues to be in contact with the heat-conducting connecting member 65 to achieve heat conduction.

[0060] It should be noted that the temperature control switch device 64 mentioned above can be a memory metal temperature controller, a phase change material temperature controller, a bimetallic strip temperature controller, a diaphragm temperature controller, or other mechanical temperature controllers; the temperature control type controllable mechanical thermal circuit mentioned above can also be constructed on the insulated container body.

[0061] Furthermore, such as Figure 10 As shown, an adjustment mechanism 66 is also provided on the container lid 3. The adjustment mechanism 66 is located outside the container lid 3 and passes through the container lid 3 to connect with the heat-conducting communication member 65, so as to drive and adjust the distance between the contacts of the heat-conducting communication member 65 and the contacts of the temperature control device 64.

[0062] By using the control mechanism 66, the gap between the heat-conducting connecting component 65 and the temperature control device 64 can be controlled, setting the temperature switching between acceleration and deceleration of heat exchange between the insulation container and the outside environment. For example, if the ambient temperature is 25℃ and the initial temperature of the contents of the insulation container is 97℃, and the user needs to keep the contents warm for a long time, the control mechanism 66 adjusts the gap between the heat-conducting connecting component 65 and the temperature control device 64 to its maximum, keeping their contact points open and minimizing the heat exchange rate between the contents and the outside environment, thus maintaining the insulation container in a long-term heat-preservation state. If the user needs the contents to quickly reach 80℃ and maintain this near-temperature for a long time, the control mechanism 66 reduces the gap between the heat-conducting connecting component 65 and the temperature control device 64, ensuring that the contact points remain open when the contents are above 80℃. When the contents of the insulated container come into contact with the outside, the heat exchange rate between the contents and the outside increases. When the contents reach 80°C or below, the contact point between the two breaks, and the heat exchange rate between the contents and the outside of the insulated container decreases to a minimum, and the insulated container is in a long-term heat preservation state. When the user needs the contents to quickly reach 56°C and maintain this close temperature for a long time, the distance between the heat-conducting connecting component 65 and the temperature control device 64 is further reduced by the regulating mechanism 66. When the contents of the insulated container are above 56°C, the thermal path is open, and the heat exchange rate increases. When the contents reach 56°C or below, the insulated container switches to a long-term heat preservation state. Assuming the ambient temperature is 25℃ and the contents are -10℃, the user needs the contents to quickly reach 0℃ and remain in the 0-5℃ range for a relatively long time. The user adjusts the distance between the shape memory metal and the adjustable contacts to an appropriate position, sets the insulation state to 0℃, closes the contacts, conducts the thermal circuit, and accelerates heat exchange. When the temperature of the contents reaches 0℃ or higher, the shape memory metal deforms, the contacts separate, the thermal circuit is broken, the heat exchange rate slows down, and the insulation container enters the insulation state.

[0063] Among them, such as Figure 10 As shown, the control mechanism 66 can be a drive bolt, which passes through the upper end plate 62 and is rotatably connected to the heat-conducting connecting member 65. Thus, rotating the drive bolt controls the up-and-down movement of the heat-conducting connecting member 65. This structure is relatively simple and easy to operate. Furthermore, a rotatable annular permanent magnet component can be added to the control mechanism, and a threaded annular permanent magnet component can be matched to the nut-type contact. Alternatively, a magnetic coupling can be formed through the permanent magnet component and the ferromagnet, controlling the rotation of the annular permanent magnet component added to the control mechanism. This drives the nut-type contact to move up and down along the threaded track, moving away from or closer to the temperature controller contact, changing the contact spacing, and constructing a magnetically controlled temperature-controlled mechanical thermal circuit. The magnetically controlled temperature-controlled mechanical thermal circuit can also use a sliding groove structure control mechanism, adjusting the contact spacing through magnetic coupling, etc., using magnetic control methods. This disclosure does not limit the scope of the invention.

[0064] The above technical solution can be extended to construct a multi-channel temperature-controlled controllable mechanical thermal circuit array on the insulated container body and its lid.

[0065] In another implementation, such as Figure 11 As shown, the temperature control switch device 64 can be a bimetallic strip temperature control switch, thus allowing adjustment of the distance between the passive contact and the bimetallic strip temperature control switch. Assuming the bimetallic strip bends as the temperature increases, and the initial temperature of the contents is 95 degrees Celsius, when the distance between the passive contact and the bimetallic strip temperature control switch is adjusted to its maximum (assuming 10 mm): even if the bimetallic strip is completely bent, it will not contact the passive contact, and the insulated container will always remain in a heat-preserving state. When the distance between the passive contact and the bimetallic strip temperature control switch is reduced to (assuming 6 mm): when the temperature of the contents is above 80 degrees Celsius, the bimetallic strip maintains contact with the passive contact, the thermal path is open, and sufficient heat exchange occurs between the inside and outside. When the temperature of the contents falls below 80 degrees Celsius... When the bimetallic strip is adjusted to close the contact with the passive contact, the bimetallic strip remains in contact with the passive contact when the temperature of the contents is above 60 degrees Celsius, the thermal path is open, and sufficient heat exchange occurs between the inside and outside. When the temperature of the contents is below 60 degrees Celsius, the bimetallic strip closes the contact with the passive contact. When the temperature of the contents is adjusted to close the contact with the passive contact, the bimetallic strip remains in contact with the passive contact even when the bimetallic strip is fully extended, and the insulated container is always in a non-insulated state. Example 7

[0066] like Figure 12 As shown, the mechanically controllable thermal circuit may include a heat-insulating component 71 with through holes, a heat-insulating sealing plate 73, and a control mechanism. The heat-insulating component 71 with through holes is disposed between the inner liner and the outer shell. The opening of the heat-insulating sealing plate covering the through holes can be adjusted by controlling the transmission component, thereby regulating the flow rate of the through holes of the heat-insulating component 71 and changing the heat exchange efficiency of the channel-type thermal circuit.

[0067] like Figure 12As shown, taking container lid 3 as an example, a heat-insulating component 71 is provided between the outer shell 31 and the inner liner 32. The heat-insulating component 71 is provided with a through hole opening 72. A movable built-in permanent magnet heat-insulating sealing plate 73 is provided at the through hole opening 72. A movable built-in magnet control component 74 is provided outside the outer shell 31. A slide 76 and a limiting component 75 are provided outside the heat-insulating component 71 and the outer shell 31 to regulate the movement stroke of the heat-insulating sealing plate 73 and the control mechanism 74. The heat-insulating sealing plate 73 and the magnet in the control component 74 are attracted to each other. Alternatively, the magnet can be attracted to a ferromagnet to form a magnetically controlled mechanical heat-conducting communication mechanism to control the change in the thermal resistance value. The movable control component 74 can drive the heat-insulating sealing plate 73 to move synchronously through magnetic force, thereby adjusting the coverage opening of the through hole opening 72 and the heat exchange ventilation, thereby changing the heat exchange efficiency of the channel-type heat path. The thermal insulation sealing plate 73 and the control component 74 can also be made without the permanent magnet component and directly fixedly connected through a connector that penetrates the outer shell. The manual control component 74 directly and mechanically links the thermal insulation sealing plate to adjust the opening degree and flow rate. The aforementioned thermal insulation sealing plate 73 can adopt a lifting opening and closing structure or a hinge flipping structure, as well as other flow control structures, which are not limited in this disclosure.

[0068] Using this structure, when it is necessary to adjust the insulation performance, the insulation sealing plate can be opened to a corresponding degree to increase the heat exchange flow. After reaching a certain temperature, the insulation sealing plate can be closed to reduce the heat exchange rate. The aforementioned channel-type mechanically controllable thermal circuit can construct multiple thermal circuits on the insulated container and its lid to improve the efficiency of heat exchange through the controllable thermal circuits.

[0069] Among them, such as Figure 12 As shown, the sliding component can be a positioning slider on the insulation component 71 and a strip-shaped sliding groove structure on the insulation sealing plate 73, so that the strip-shaped sliding groove cooperates with the positioning slider. In this way, when the insulation sealing plate 73 is moved, it can move along the direction of the strip-shaped sliding groove, preventing it from deviating. After the limiting component is set on the other side of the insulation component 71 opposite to the insulation sealing plate 73, after the insulation sealing plate 73 abuts against the limiting component 75, the insulation sealing plate 73 completely closes the through hole opening 72. Example 8

[0070] like Figure 13 As shown, for ease of observation and control, a thermometer 37 can be installed on the insulated container or its lid to display the temperature of the contents.

[0071] The thermometer 37 can be either a commonly used bimetallic thermometer or a liquid crystal thermometer, to measure the temperature inside the container.
