Description

Technical Field

[0001] This invention relates to the field of thermal insulation container technology, specifically to a cylindrical telescopic mechanism, a container, and a temperature-controlled thermal insulation container. Background Technology

[0002] Insulated containers are containers that slow down heat transfer and maintain the temperature of their contents. These include insulated cups, flasks, containers, buckets, lunch boxes, travel mugs, children's water bottles, office water bottles, and other everyday insulated products. Existing vacuum insulated cups and flasks rely on a double-layer vacuum structure to block heat convection and radiation, providing long-lasting insulation. However, they cool down very slowly after boiling water is poured in, making them unsuitable for quick drinking. Conventional fast-cooling cups often use phase change materials, switchable heat-conducting structures, and external heat dissipation devices to achieve cooling, but these methods suffer from drawbacks such as complex structures, high costs, poor reliability, short lifespan, and an inability to simultaneously provide long-lasting insulation.

[0003] Traditional single-layer insulated containers cool down quickly but lack insulation capabilities; vacuum insulated containers offer excellent insulation but cannot achieve rapid cooling. Current technology struggles to integrate passive rapid cooling, passive temperature measurement, smart mobile alerts, and long-term insulation switching functions simultaneously within a single container. This fails to meet users' needs for "rapidly changing boiling water to warm water and maintaining the temperature of warm water for an extended period." Summary of the Invention

[0004] In view of the above-mentioned prior art, the present invention provides a cylindrical telescopic mechanism, a container, and a temperature-controlled insulated container.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention first provides a cylindrical telescopic mechanism, comprising: a cylindrical body, the cylindrical body including an upper cylindrical body and a lower cylindrical body; a fastening collar, the fastening collar being sleeved on the upper cylindrical body and the lower cylindrical body, the fastening collar being connected to the upper cylindrical body by mutually fitting bosses and grooves, one of the bosses and grooves being provided on the upper cylindrical body, and the other two being provided on the fastening collar; the fastening collar being threadedly connected to the lower cylindrical body; and a circumferential limiting member, the circumferential limiting member being connected between the upper cylindrical body and the lower cylindrical body, for limiting the relative circumferential movement of the upper cylindrical body and the lower cylindrical body.

[0007] In this design, the fastening collar and the upper cylinder are connected by an annular boss and an annular groove structure. This connection method does not create circumferential constraints, allowing the fastening collar to rotate freely around the upper cylinder, while providing reliable axial limiting and support. Furthermore, the fastening collar and the lower cylinder are connected by threads. Rotating the fastening collar drives the lower cylinder to move axially relative to the upper cylinder, achieving continuous adjustment of the cylinder length. Simultaneously, circumferential limiting components restrict the relative rotation between the upper and lower cylinders, preventing the lower cylinder from rotating synchronously with the fastening collar during adjustment, thus effectively converting rotational operation into stable axial extension and retraction. In practical use, only a single operation on the fastening collar is required to complete the cylinder extension and retraction, avoiding the inconvenience of operating multiple components separately. This design is applicable to equipment structures requiring length adjustment, such as pipe connections and equipment extension components. This design is also suitable for length adjustment of a portion of a container shell.

[0008] Furthermore, in the description of this solution, the phrase "the circumferential limiting member is connected between the upper and lower cylinders" is not limited to the spatial concept of "between" the upper and lower cylinders, but rather to the logical concept of "between." For example, it can be achieved through a third component. Regardless of the position of the third component, as long as the third component remains fixed to the upper cylinder in the circumferential direction, and the third component restricts the circumferential movement of the lower cylinder, the invention's objective can be achieved. Taking the container of this patent embodiment as an example, the invention's objective can be achieved by setting a stop on the inner liner of the container to restrict the rotation of the lower cylinder.

[0009] Preferably, the upper cylinder is provided with an upper fixing ring, the boss or groove is provided on the upper fixing ring, the lower cylinder is provided with a lower fixing ring, and the lower fixing ring is provided with threads.

[0010] In this design, the lower fixing ring and the lower fixing ring can be used to easily set bosses, grooves or threads, which facilitates processing.

[0011] Preferably, the circumferential limiting member is an elastic ring, which is connected between the upper cylinder and the lower cylinder. When the fastening ring is rotated, the lower cylinder causes the elastic ring to compress or stretch.

[0012] In this design, the elastic ring is positioned "between" the upper and lower cylinders, enhancing the seal between them to some extent. Its elasticity allows it to compress or stretch as the lower cylinder moves up and down, while also applying elastic or tensile force to prevent relative swaying. The elastic ring can be a bellows ring (pipe) or a hollow sealing ring, especially a metal bellows ring, or a rigid (metal) ring. When compressed, the rigid ring bends into an arc shape.

[0013] Preferably, the upper and lower ends of the elastic ring are sealed to the upper cylinder and the lower cylinder, respectively.

[0014] In this design, the elastic ring ensures that the gap between the upper and lower cylinders is sealed, making the cylinder as a whole a sealed unit, preventing gas or fluid from leaking out.

[0015] The present invention also provides a container, including a container liner, a container shell, and a container lid, wherein the upper end of the container liner and the upper end of the container shell are connected together to form a double-layer heat-insulating structure, and the container also includes the aforementioned cylindrical telescopic mechanism, wherein the container shell has the cylindrical body.

[0016] In this design, a portion of the container's outer shell forms a cylindrical body, which is telescopic. By adjusting the fastening ring, the overall height or internal dimensions of the container can be altered, thus achieving flexible volume adjustment. Compared to fixed-structure containers, this design ensures a stable connection between the inner liner and the outer shell while allowing the container to adapt to different capacity requirements or storage conditions, improving usability. Furthermore, the telescopic structure combined with a double-layer insulation system maintains good thermal insulation performance under varying telescopic states, balancing structural adjustability with excellent insulation.

[0017] This invention also provides a temperature-controlled insulated container, including the aforementioned container. The inner liner of the container is provided with a heat-conducting protrusion structure, and the outer shell of the container is provided with a heat-conducting protrusion structure. Under normal conditions, there is a gap between the heat-conducting protrusion structure of the inner liner and the heat-conducting protrusion structure of the outer shell. When the fastening ring is rotated, the lower cylinder moves up and down, causing the heat-conducting protrusion structure of the outer shell to move up and down until the heat-conducting protrusion structure of the inner liner and the heat-conducting protrusion structure of the outer shell come into contact.

[0018] In this design, the relative positions of the outer shell and inner liner of the container are changed by extending and retracting the cylinder. This controls the contact and separation of the heat-conducting protrusions on the inner and outer shells. When in contact, a thermal bridge is formed, allowing heat to be conducted outwards, thus achieving cooling. When separated, the thermal bridge breaks, blocking heat conduction from the inside out, thereby achieving insulation. Advantageously, both the inner and outer shells are made of thermally conductive materials such as metal, resulting in even better cooling performance.

[0019] Preferably, the heat-conducting protrusion structure of the inner liner of the container is disposed on the outer side of the inner liner of the container, and the heat-conducting protrusion structure of the outer shell of the container is disposed on the inner side of the outer shell of the container, and the heat-conducting protrusion structures of the inner liner and the outer shell are staggered.

[0020] And / or,

[0021] The heat-conducting protrusion structure of the inner liner of the container is located on the bottom outer side of the inner liner of the container, and the heat-conducting protrusion structure of the outer shell of the container is located on the bottom inner side of the outer shell of the container.

[0022] This solution offers two heat conduction methods, one or a combination of side and bottom. When it is on the side, the cooling is fast due to the large heat conduction area. When it is on the bottom, the heat conduction protrusion structure inside the container can be called the heat conduction and heat dissipation seat inside the container, and the heat conduction protrusion structure outside the container can be called the heat conduction and heat dissipation seat outside the container. This method has a relatively slow cooling due to the small heat conduction area, and is suitable for users who do not need to cool down quickly.

[0023] Preferably, both the inner liner and the outer shell of the container are metal walls and have a corrugated structure, wherein the corrugated structures of the inner liner and the outer shell are staggered, and the protrusions of the corrugated structures respectively form the heat-conducting protrusion structure of the inner liner and the heat-conducting protrusion structure of the outer shell.

[0024] In this design, the structure significantly improves the sidewall stiffness through arched corrugations, enhancing its resistance to deformation and compression. The staggered arrangement avoids direct contact between the inner and outer liner, effectively blocking thermal bridges and ensuring vacuum insulation performance. At the same time, the corrugated shape increases the heat exchange area, and when the crests correspond at specific locations, it can enhance local heat conduction and dissipation, achieving accelerated cooling. The corrugated outer wall also improves the grip friction characteristics, enhancing operational stability.

[0025] Preferably, the bottom of the container shell extends downward to form the cylinder, the lower cylinder extends inward and then upward, the upward-extending part is called the heat dissipation support sleeve, and the upper end of the heat dissipation support sleeve is connected to the heat-conducting protrusion structure of the container shell; the heat-conducting protrusion structure of the container liner is set on the bottom outer side of the container liner, corresponding to the heat-conducting protrusion structure of the container shell.

[0026] This design places the cooling-insulation switching mechanism at the bottom of the container. Through the axial contact and separation of a high thermal conductivity heat sink, controllable switching between heat conduction and insulation states is achieved, ensuring a clear heat transfer path and rapid response. During the switching process, the relative positions of the inner and outer shells remain unchanged; the functional conversion is completed solely by the movement of the heat sink, resulting in high structural stability and lower processing and assembly difficulty. Furthermore, the switching action is completed within the insulation layer, which helps maintain overall sealing and insulation performance.

[0027] Preferably, a vacuum is formed between the inner liner of the container and the outer shell of the container.

[0028] The present invention also provides a temperature-controlled insulated container, comprising the above-mentioned container, wherein the bottom of the container shell is provided with a lower air inlet, and the upper part of the lower cylinder is provided with an upper air outlet and an upper air outlet sealing ring; the bottom of the container liner is provided with a container liner bottom sealing gasket, and the bottom of the container shell is provided with a container shell bottom sealing gasket corresponding to the container liner bottom sealing gasket. Under normal conditions, the container liner bottom sealing gasket and the container shell bottom sealing gasket are in contact, and the upper air outlet sealing ring seals the upper air outlet. When the fastening ring is rotated, the lower cylinder moves downward, causing the container shell bottom sealing gasket to move downward, and the lower air inlet and the upper air outlet open.

[0029] This solution achieves controllable opening and closing of the air convection channel by incorporating upper and lower air vents and their sealing structures within the insulation layer, in conjunction with a cooling-insulation switching mechanism. In cooling mode, the upper air outlet and lower air inlet form a channel, utilizing the "chimney effect" to promote natural air convection, allowing for rapid heat release from the inner liner and significantly improving cooling efficiency. In insulation mode, the sealing structure restores a relatively enclosed space, reducing convective heat transfer and maintaining basic insulation performance. Compared to the aforementioned solutions, this solution has a simplified structure, reduced reliance on vacuum, and lower manufacturing costs, while simultaneously providing both rapid cooling and a certain level of insulation capability, making it suitable for applications requiring high cooling response.

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] In this embodiment, the insulated container is not limited. It should be understood that the temperature-controlled insulated container of the present invention can be a thermos cup or other types of containers. For ease of explanation, the following detailed description will use a thermos cup as an example. The accompanying drawing of the insulated container of the present invention is a structural drawing of a thermos cup. The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] Example 1

[0063] like Figures 1 to 6 The figure shows a first embodiment of the temperature-controlled heat-insulating container of the present invention, including a container body (1), a container lid (2), a cooling-heat-insulating switching mechanism (3), a heat-conducting metal protrusion structure (401) for the container liner, a heat-conducting metal protrusion structure (402) for the container shell, a high-thermal-conductivity heat dissipation seat (403) for the container liner, and a high-thermal-conductivity heat dissipation seat (404) for the container shell; the container body (1) includes a container liner (101) and a container shell (102); the container lid (2) includes a container lid metal shell (201), a container lid threaded inner cover (202), and a silicone sealing gasket (203); the cooling-heat-insulating switching mechanism (3) is composed of an upper fixing ring (301), a fastening collar (302), an elastic ring (303), and a lower fixing ring (304); The fastening collar (302) in the cooling-insulation switching mechanism (3) has an internal thread, and the lower fixing ring (304) has an external thread. The upper boss (308) of the fastening collar (302) is engaged in the groove (309) of the upper fixing ring (301). The internal thread (305) of the fastening collar and the external thread (307) of the lower fixing ring are connected. The cooling-insulation switching mechanism (3) and the container shell (102) are welded or sealed together as an integral structure. The cooling-insulation switching mechanism (3) is installed at any position on the container shell (102). In this embodiment, it is installed at the upper part of the container shell (102) and the lower part of the container cover (2). The container shell (102), the container liner (101) and the cooling-insulation switching mechanism (3) form a vacuum insulation jacket (5). It also includes a passive temperature measuring tag (8), which is installed in the vacuum insulation interlayer (5) and fixed at any position in the inner liner (101). In this embodiment, it is installed at the bottom of the inner liner (101). The passive temperature measuring tag (8) is a battery-free RFID / NFC temperature measuring tag, fixed on the outer wall of the inner liner, and can be woken up by mobile phone radio frequency and transmit real-time temperature to the outside. Using a smartphone with NFC / RFID function and a temperature management application, when the application detects that the water temperature has dropped to the set threshold, it will automatically issue one or more of the following warnings: sound, vibration, pop-up window, and notification bar reminder.

[0064] The heat-conducting metal protrusion structure (401) on the outer wall of the container liner (101) is welded or sealed and bonded to the container liner (101) as an integral structure; the heat-conducting metal protrusion structure (402) on the inner wall of the container shell (102) is welded or sealed and bonded to the container shell (102) as an integral structure; the high thermal conductivity heat dissipation seat (403) at the bottom of the container liner (101) is welded or sealed and bonded to the container liner (101) as an integral structure; the high thermal conductivity heat dissipation seat (404) at the bottom of the container shell (102) is welded or sealed and bonded to the container shell (102) as an integral structure; the above temperature control structures (4) are all located inside the vacuum insulation interlayer (5).

[0065] The heat-conducting metal protrusion structure (401) of the inner liner and the heat-conducting metal protrusion structure (402) of the outer shell are evenly distributed around the container body (1) in a staggered arrangement with no overlap in radial projection. That is, the gap between the heat-conducting metal protrusion of the inner liner (101) and the heat-conducting metal protrusion of the outer shell (102) is the same as the gap between the heat-conducting metal protrusion of the inner liner (101). There is no contact between the heat-conducting metal protrusion structure (401) of the inner liner and the heat-conducting metal protrusion structure of the outer shell in the vacuum insulation layer (5). The high thermal conductivity heat sink (403) of the inner liner and the high thermal conductivity heat sink (404) of the outer shell have the same gap as the above protrusion structure, ensuring the vacuum state between the inner liner (101) and the outer shell (102), blocking the heat conduction from the inside to the outside, so as to achieve the heat preservation effect.

[0066] The thermally conductive metal protrusion structure and the high thermal conductivity heat sink are made of copper, aluminum alloy, or high thermal conductivity stainless steel.

[0067] When it is necessary to lower the temperature of the liquid in the insulation container, the fastening ring (302) of the cooling-insulation switching mechanism (3) can be manually or electrically driven to compress the elastic ring corrugation (306), and the lower fixing ring (304) connects to pull the outer shell of the container (102) to move upward; in the vacuum insulation jacket (5), the inner container shell (102) drives the heat-conducting metal protrusion structure (402) of the outer shell and the high heat conductivity heat sink (404) of the outer shell to move upward together; the side of the heat-conducting metal protrusion structure (402) of the outer shell and the side of the heat-conducting metal protrusion structure (401) of the inner liner of the container are close together, and at the same time, the high heat conductivity heat sink (404) of the outer shell and the high heat conductivity heat sink (403) of the inner liner of the container are also close together; at this time, the insulation container changes from a vacuum insulation state to a metal heat conduction state.

[0068] Heat inside the insulated container is quickly conducted to the outside of the insulated container through the metal, and the liquid inside the insulated container drops rapidly; when the user brings his mobile phone close to the passive temperature sensor (8), the temperature is automatically read and compared with the set threshold; when the liquid temperature reaches the user's set temperature, the mobile phone issues an alarm.

[0069] The user can stretch the elastic ring corrugation (306) by manually or electrically driving the fastening collar (302) of the cooling-insulation switching mechanism (3), and the lower fixing ring (304) connects to the traction container shell (102) to move downward; the heat-conducting metal protrusion structure (402) of the container shell and the heat-conducting metal protrusion structure (401) of the container liner gradually separate, and at the same time, the high heat conductivity heat sink (404) of the container shell and the high heat conductivity heat sink (403) of the container liner gradually separate, at which time the heat-insulating container changes from a metal heat-conducting state to a vacuum heat-insulating state.

[0070] Under the premise of ensuring a complete vacuum, the cooling-insulation switching is carried out within the vacuum insulation jacket (5), realizing a reliable switching between vacuum insulation and rapid cooling. This insulated container achieves rapid cooling of the internal high-temperature liquid while ensuring a reliable and long-lasting vacuum insulation effect through a complete vacuum insulation structure.

[0071] When using the first embodiment of the temperature-controlled insulated container of the present invention, the side of the heat-conducting metal protrusion structure (402) of the outer shell of the container and the side of the heat-conducting metal protrusion structure (401) of the inner liner of the container need to be close together to achieve the metal heat conduction state. There is no intermediate state. For some users who need to gradually cool down, such as needing the hand warming function of the insulated container, in order to meet this need, it is necessary to control the contact area of ​​the heat-conducting metal protrusion structure, thereby controlling the heat conducted from the inner liner (101) of the container to the outer liner of the container. This is how the second embodiment of the temperature-controlled insulated container of the present invention is produced.

[0072] Example 2

[0073] like Figures 7 to 8 The diagram shows a second embodiment of the temperature-controlled insulated container according to the present invention, including a container body (1), a container cover (2), a cooling-insulating switching mechanism (3), a heat-conducting metal protrusion structure (401) for the inner liner of the container, a heat-conducting metal protrusion structure (402) for the outer shell of the container, a high heat-conducting heat sink for the inner liner of the container (403) and a high heat-conducting heat sink for the outer shell of the container (404). In order to achieve the purpose of brief description, any technical features that can be applied in the first embodiment of the temperature-controlled insulated container of the present invention are described herein and need not be repeated.

[0074] The heat-conducting metal protrusions (401) of the inner liner and the heat-conducting metal protrusions (402) of the outer shell are evenly distributed around the container body (1) and are staggered. Their radial projections do not overlap. That is, the gap between the heat-conducting metal protrusions of the inner liner (101) and the heat-conducting metal protrusions of the outer shell (102) are the same as the gap between the heat-conducting metal protrusions of the outer shell (102) and the heat-conducting metal protrusions of the inner liner (101). There is no contact between the heat-conducting metal protrusions (401) of the inner liner and the heat-conducting metal protrusions of the outer shell in the vacuum insulation layer (5). The high thermal conductivity heat sink (403) of the inner liner and the high thermal conductivity heat sink (404) of the outer shell have a gap that fits completely with the above protrusions, ensuring the vacuum state between the inner liner (101) and the outer shell (102), blocking heat conduction from the inside to the outside, so as to achieve the heat preservation effect.

[0075] Unlike the first embodiment of the temperature-controlled insulated container of the present invention, the outer diameter of the inner heat-conducting metal protrusion structure (401) of the container in the second embodiment of the temperature-controlled insulated container of the present invention is smaller than the inner diameter of the outer heat-conducting metal protrusion structure (402); different gaps are designed according to the expansion coefficients of different metals to ensure that the outer heat-conducting metal protrusion structure (402) and the inner heat-conducting metal protrusion structure (401) of the container fit together freely without jamming.

[0076] When it is necessary to reduce the temperature of the liquid in the insulation container, the fastening ring (302) of the cooling-insulation switching mechanism (3) can be manually or electrically driven to compress the elastic ring corrugation (306), and the lower fixing ring (304) connects to pull the container shell (102) to move upward; in the vacuum insulation jacket (5), the inner container shell (102) drives the container shell heat-conducting metal protrusion structure (402) and the container shell high heat conductivity heat sink (404) to move upward together; the inner circumferential surface of the container shell heat-conducting metal protrusion structure (402) gradually approaches the outer circumferential surface of the container inner liner heat-conducting metal protrusion structure (401) until the two circumferential surfaces are close together, and at the same time, the container shell high heat conductivity heat sink (404) and the container inner liner high heat conductivity heat sink (403) are also close together; at this time, the insulation container changes from a vacuum insulation state to a metal heat conduction state. At the same time, during the process of the insulation container changing from a vacuum insulation state to a maximum metal heat conduction state, the heat transfer is also a continuously increasing process as the contact area increases. Users can choose to stay in any heat dissipation equilibrium state according to their personal needs or hand warming temperature.

[0077] Heat inside the insulated container is conducted to the outside of the insulated container through metal, and the water temperature inside the insulated cup drops rapidly; when the user's mobile phone is close to the passive temperature measuring tag (8), the temperature is automatically read and compared with the set threshold; when the liquid temperature reaches the user's set temperature, the mobile phone issues an alarm; the user can stretch the elastic ring corrugation (306) by manually or electrically driving the fastening ring (302) of the cooling-insulation switching mechanism (3), and the lower fixing ring (304) is connected to pull the container shell (102) to move downward; the heat-conducting metal protrusion structure (402) of the container shell and the heat-conducting metal protrusion structure (401) of the container liner gradually separate, and at the same time, the high heat conduction heat sink (404) of the container shell and the high heat conduction heat sink (403) of the container liner separate, at which time the insulated container changes from a metal heat conduction state to a vacuum heat preservation state.

[0078] Under the premise of ensuring a complete vacuum, the cooling-insulation switching is carried out within the vacuum insulation jacket (5), realizing a reliable switching between vacuum insulation and rapid cooling. This insulated container achieves rapid cooling of the internal high-temperature liquid while ensuring a reliable and long-lasting vacuum insulation effect through a complete vacuum insulation structure.

[0079] When using the first and second embodiments of the temperature-controlled insulated container of the present invention, it is necessary to add a heat-conducting metal protrusion structure (402) on the side of the container shell and a heat-conducting metal protrusion structure (401) in the container liner. Due to the coaxiality of the container shell (102) and the container liner (101) and the thickness of the vacuum layer between them, the processing is difficult and the production cost is high. In order to reduce the processing difficulty and cost and meet market demand, the third embodiment of the temperature-controlled insulated container of the present invention was developed.

[0081] like Figures 9 to 11 The following is a third embodiment of the temperature-controlled insulated container according to the present invention, including a container body (1), a container cover (2), a cooling-insulation switching mechanism (3), a container inner liner protrusion structure (405), a container outer shell protrusion structure (406), a container inner liner longitudinal reinforcing rib (407), a container outer shell longitudinal reinforcing rib (408), a container inner liner high thermal conductivity heat dissipation seat (403), and a container outer shell high thermal conductivity heat dissipation seat (404). In order to achieve the purpose of brief description, any technical features that can be applied in the above embodiments are described herein, and there is no need to repeat the same description.

[0082] In a third embodiment of the temperature-controlled insulated container of the present invention, a regular corrugated structure is extruded from the metal wall of the container liner (101) and the metal wall of the container shell (102). The shapes of the convex structures (405) of the container liner and the convex structures (406) of the container shell can be trapezoidal corrugations, circular arc corrugations, sine corrugations, and triangular corrugations, etc. The convex structures (405) of the container liner and the convex structures (406) of the container shell are evenly distributed along the circumference of the container body (1), and the two are staggered and have no overlap in radial projection, that is, the convex structures of the container liner. (405) corresponds to the gap between the outer shell protrusions (406) and the inner liner protrusions (405); there is no contact between the inner liner protrusions (405) and the outer shell protrusions (406) in the vacuum insulation jacket (5); there is a gap between the inner liner high thermal conductivity heat sink (403) and the outer shell high thermal conductivity heat sink (404) when they are fully fitted with the above protrusions, so that the thickness of the vacuum insulation jacket (5) is uniform and the inner and outer liners are not fitted together.

[0083] Under vacuum negative pressure, the inner and outer corrugations enhance the rigidity of the side walls through their arched structure, improving the cup's resistance to deformation and compression. The staggered corrugation structure effectively prevents contact between the inner and outer liner, blocking thermal bridges and ensuring vacuum insulation. Simultaneously, the corrugated structure increases the heat exchange area of ​​the inner and outer walls; when the crests of the inner and outer walls overlap, heat transfer and dissipation are accelerated, achieving rapid cooling. Furthermore, the outer liner's corrugations improve grip and anti-slip properties. In addition, the combination of double corrugations and vacuum provides 2-3 times the resistance to negative pressure and impact compared to ordinary straight-walled cups.

[0084] To prevent the inner liner protrusion structure (405) and outer shell protrusion structure (406) from connecting, a very small number of point-like or ring-shaped heat-insulating ceramic or heat-insulating material supports can be provided in the vacuum layer to ensure the vacuum gap between the inner liner protrusion structure (405) and outer shell protrusion structure (406). Although the inner liner protrusion structure (405) and outer shell protrusion structure (406) enhance the stress state that traditional straight walls are prone to inward indentation under the negative pressure of the vacuum insulation interlayer (5), the inner liner protrusion structure (405) and outer shell protrusion structure (406) are subjected to two opposite forces under axial atmospheric pressure. In order to control the deformation of the inner liner (101) and outer shell (102) after being subjected to force, longitudinal reinforcing ribs (407) of the inner liner (101) are added to the inner wall of the inner liner (101), and longitudinal reinforcing ribs (408) of the outer shell (102) are added to the outer wall of the outer shell (102). The number of the reinforcing ribs is selected to be an even number of more than 4 to consider uniform stress.

[0085] When it is necessary to lower the temperature of the liquid in the insulated container, the fastening ring (302) of the cooling-insulation switching mechanism (3) can be manually or electrically driven to compress the elastic ring corrugation (306), and the lower fixing ring (304) is connected to pull the outer shell of the container (102) to move upward; the inner circumferential surface of the inner shell protrusion structure (406) of the vacuum insulation interlayer (5) gradually approaches the outer circumferential surface of the inner liner protrusion structure (405) until the two circumferential surfaces are close together. At the same time, the high thermal conductivity heat dissipation seat (404) of the outer shell and the high thermal conductivity heat dissipation seat (403) of the inner liner are also close together; at this time, the insulated container changes from a vacuum insulation state to a metal thermal conductivity state similar to a single-layer thick-walled container. The heat inside the insulated container is conducted to the outside of the insulated container through the metal, and the water temperature inside the insulated container drops rapidly; at the same time, during the process of the insulated container changing from a vacuum insulation state to a maximum metal thermal conductivity state, the heat transfer is a continuous increasing process. The user can stay in any heat balance state according to personal needs or hand warming temperature.

[0086] To protect user safety and prevent burns, the outer shell (102) of the container is fitted with a decorative heat-resistant protective sleeve (9) made of plastic, silicone, leather, or other heat-insulating materials. The heat-resistant protective sleeve (9) has evenly spaced heat dissipation holes (10), which correspond to the recessed parts of the outer shell (102) (which are also the protruding structures of the outer shell (102) within the vacuum insulation layer (5)). A temperature-sensing strip can also be installed on the heat-resistant protective sleeve (9), which can display different colors according to the water temperature. Users can directly perceive the temperature of the liquid inside the container based on the different colors of the temperature-sensing strip.

[0087] During the process of the liquid temperature inside the insulated container decreasing, the mobile phone is brought close to the passive temperature measuring tag (8) and automatically reads the temperature and compares it with the set threshold. When the liquid temperature reaches the user's set temperature, the mobile phone issues an alarm. The user can stretch the elastic ring corrugation (306) by manually or electrically driving the fastening ring (302) of the cooling-insulation switching mechanism (3). The lower fixing ring (304) is connected to pull the container shell (102) to move downward. The heat-conducting metal protrusion structure (402) of the container shell and the heat-conducting metal protrusion structure (401) of the container liner gradually separate. At the same time, the high heat conductivity heat sink (404) of the container shell and the high heat conductivity heat sink (403) of the container liner separate. At this time, the insulated container changes from a metal heat conduction state to a vacuum heat preservation state.

[0088] The cooling-insulation switching is carried out within the vacuum insulation jacket (5), ensuring a reliable switch between vacuum insulation and rapid cooling while maintaining a complete vacuum. This insulated container achieves rapid cooling of the internal high-temperature liquid while ensuring a reliable and long-lasting vacuum insulation effect through a complete vacuum insulation structure.

[0089] When using the first to third embodiments of the temperature-controlled insulated container of the present invention, all three embodiments have a complete vacuum insulation jacket (5), and through the cooling-insulation switching mechanism (3), the container inner liner (101) and the container outer shell (102) are directly connected or indirectly connected through a high thermal conductivity material, so that the heat inside the insulated container is conducted to the outside of the insulated container through the metal, and the water temperature inside the insulated container drops rapidly. The advantages of the three embodiments are that the metal conduction area is large and the cooling is fast. The disadvantages are that the heat-conducting metal protrusion structure (401) of the container inner liner and the heat-conducting metal protrusion structure (402) of the container outer shell need to be precisely matched, and the protrusion structure (405) of the container inner liner and the protrusion structure (406) of the container outer shell also need to be precisely matched. The processing technology standards are high and the cost is high, which is suitable for the needs of the mid-to-high-end market. For users who do not need to cool down quickly, a heat dissipation structure consisting only of a high thermal conductivity heat dissipation base (403) for the inner liner of the container and a high thermal conductivity heat dissipation base (404) for the outer shell of the container can be selected. Alternatively, the bottom of the inner liner (101) of the vacuum insulation interlayer (5) and the bottom of the outer shell (102) of the container can be separated and connected for heat conduction. This results in the fourth embodiment of the temperature-controlled insulation container of the present invention.

[0090] Example 4

[0091] like Figures 12 to 13 The above describes a fourth embodiment of a temperature-controlled insulated container according to the present invention, including a container body (1), a container cover (2), a cooling-insulation switching mechanism (3), a high thermal conductivity heat dissipation base (403) for the inner liner of the container, and a high thermal conductivity heat dissipation base (404) for the outer shell of the container. For the purpose of brief description, any technical features that can be applied in the above embodiments are described herein and need not be repeated.

[0092] Unlike the first to third embodiments of the temperature-controlled insulated container of the present invention, the cooling-insulation switching mechanism (3) of this embodiment is located on the bottom side of the container shell (102). Similar to ordinary insulated containers, except that the container liner (101) and the container shell (102) are connected at the cup mouth, the container shell (102), the container liner (101) and the cooling-insulation switching mechanism (3) form a vacuum insulation interlayer (5); the passive temperature measuring tag (8) is installed in the vacuum insulation interlayer (5) and fixed at any position of the container liner (101). In this embodiment, it is located at the bottom of the container liner (101). The container inner liner (101) is welded or sealed together with the container inner liner (403) at the bottom of the container inner liner (101) as an integral structure; the container outer shell (102) is welded or sealed together with the container outer shell (102) at the bottom of the container outer shell (102) as an integral structure; the above temperature control structures (4) are all located in the vacuum insulation interlayer (5).

[0093] When it is necessary to lower the temperature of the liquid in the insulation container, the fastening ring (302) of the cooling-insulation switching mechanism (3) can be manually or electrically driven to compress the elastic ring corrugation (306), and the lower fixing ring (304) connects to the bottom of the traction container shell (102) to move upward; the high thermal conductivity heat dissipation seat (404) of the container shell and the high thermal conductivity heat dissipation seat (403) of the container liner are also close together; at this time, the insulation container changes from a vacuum insulation state to a metal thermal conductivity state, and the heat inside the insulation container is quickly conducted to the outside of the insulation container through the metal, and the liquid inside the insulation container is rapidly cooled. Low; the user brings their mobile phone close to the passive temperature measuring tag (8), automatically reads the temperature and compares it with the set threshold; when the liquid temperature reaches the user's set temperature, the mobile phone issues an alarm; the user can stretch the elastic ring corrugation (306) by manually or electrically driving the fastening ring (302) of the cooling-insulation switching mechanism (3), and the lower fixing ring (304) is connected to pull the container shell (102) to move downward; the high thermal conductivity heat sink (404) of the container shell and the high thermal conductivity heat sink (403) of the container liner separate, at which time the heat-insulating container changes from a metal thermal conductivity state to a vacuum heat-insulating state. The cooling-insulation switching is carried out in the vacuum heat-insulating jacket (5),

[0094] This insulated container achieves reliable switching between vacuum insulation and rapid cooling while ensuring a complete vacuum. It rapidly cools the internal high-temperature liquid while ensuring reliable and long-lasting vacuum insulation through a complete vacuum insulation structure.

[0095] When using the first to fourth embodiments of the temperature-controlled insulated container of the present invention, the cooling-insulation switching mechanism (3) is located on the side wall of the container shell (102). The advantage is that the metal has a large heat conduction area and cools down quickly. However, due to the vacuum state of the container, the inner thread (305) of the fastening ring and the outer thread (307) of the lower fixing ring of the cooling-insulation switching mechanism (3) are affected by the resultant force, and a certain driving force is required to rotate the fastening ring (302). The specific value is proportional to the cross-sectional area of ​​the cooling-insulation switching mechanism (3). In order to reduce the driving force of the fastening ring (302) and make it more suitable for the elderly and children, the fifth embodiment of the temperature-controlled insulated container of the present invention was produced.

[0096] Example 5

[0097] like Figures 14 to 17 The following is a fifth embodiment of the temperature-controlled heat-insulating container according to the present invention, including a container body (1), a container cover (2), a cooling-heat-insulating switching mechanism (3), a high thermal conductivity heat dissipation seat (403) for the inner liner of the container, and a high thermal conductivity heat dissipation seat (404) for the outer shell of the container; In order to achieve the purpose of brief description, any technical features that can be applied in the above embodiments are described herein, and there is no need to repeat the same description.

[0098] Unlike the first to fourth embodiments of the temperature-controlled insulated container of the present invention, the cooling-insulation switching mechanism (3) in this embodiment is located at the bottom of the container shell (102). Similar to ordinary insulated containers, except that the container liner (101) and the container shell (102) are connected at the cup mouth, the container shell (102), the container liner (101), the cooling-insulation switching mechanism (3) and the upper fixing ring sealing plate (310) form a vacuum insulation interlayer (5); the passive temperature measuring tag (8) is installed in the vacuum insulation interlayer (5) and fixed at any position of the container liner (101). In this embodiment, it is located at the bottom of the container liner (101). The container inner liner (101) and the container inner liner (101) are welded or sealed together as an integral structure; the container outer shell (102) and the container outer shell (102) are welded or sealed together as an integral structure; the container outer shell (102) and the container outer shell (102) are welded or sealed together as an integral structure; the upper fixing ring (301), the fastening ring (302), the elastic ring (303) and the lower fixing ring (304) in the cooling-heat preservation switching mechanism (3) are welded or sealed together as an integral structure. The sealing and bonding are integrated into one structure; the bottom of the lower fixing ring (304) and the container shell (102) are welded or sealed and bonded into one structure; the upper fixing ring (301) and the upper fixing ring sealing plate (310) are welded or sealed and bonded into one structure; one end of the heat dissipation seat support sleeve (311) is connected to the high thermal conductivity heat dissipation seat (404) of the container shell, and the other end is welded or sealed and bonded to the upper fixing ring sealing plate (310); the heat dissipation seat support sleeve (311) is located inside the vacuum insulation interlayer (5).

[0099] When it is necessary to lower the temperature of the liquid in the insulation container, the fastening ring (302) of the cooling-insulation switching mechanism (3) can be manually or electrically driven to compress the elastic ring corrugation (306). The upper fixing ring (301) and the upper fixing ring sealing plate (310) push the heat sink support sleeve (311) and the container shell high thermal conductivity heat sink (404) to move upward together. When the container shell high thermal conductivity heat sink (404) and the container inner liner high thermal conductivity heat sink (403) gradually come together, the insulation container changes from a vacuum insulation state to a metal thermal conductivity state. The heat inside the insulation container is quickly conducted to the outside of the insulation container through the metal, and the liquid inside the insulation container drops rapidly. The user brings the mobile phone close to the passive temperature measuring tag (8) to automatically read the temperature and compare it with the set threshold. When the liquid temperature reaches the user's set temperature, the mobile phone issues an alarm.

[0100] The user can manually or electrically drive the fastening ring (302) of the cooling-insulation switching mechanism (3) to stretch the elastic ring corrugation (306). The upper fixing ring (301) and the upper fixing ring sealing plate (310) pull the heat sink support sleeve (311) and the container shell high thermal conductivity heat sink (404) to move downward together. The container shell high thermal conductivity heat sink (404) and the container inner liner high thermal conductivity heat sink (403) gradually separate. At this time, the heat-insulating container changes from a metal thermal conductivity state to a vacuum heat-insulating state.

[0101] Under the premise of ensuring a complete vacuum, the cooling-insulation switching is carried out within the vacuum insulation jacket (5), realizing a reliable switching between vacuum insulation and rapid cooling. During the switching process of insulation and cooling, the relative positions of the outer shell (102) and the inner liner (101) of the container remain unchanged. Only the high thermal conductivity heat dissipation base (404) of the outer shell of the container moves up and down. The processing difficulty is small, the cost is low, and the driving force is small, making it more suitable for most people. This insulated container achieves rapid cooling of the internal high-temperature liquid while ensuring a reliable and long-lasting vacuum insulation effect of the entire container through a complete vacuum insulation structure.

[0102] When using the first to fifth embodiments of the temperature-controlled insulated container of the present invention, the container shell (102), the container liner (101), and the cooling-insulation switching mechanism (3) form an insulation interlayer, which is a vacuum insulation interlayer (5). When the insulation interlayer is a non-vacuum insulation interlayer (6), or when the insulation interlayer is filled with an insulation layer (7), the insulation interlayer can be a non-flowing air medium, or it can be an insulation layer (7) with extremely low thermal conductivity welded or sealed to the inner wall of the container shell (102). The insulation layer (7) is one or a combination of aerogel, glass wool, polyurethane, and vacuum insulation board. A certain gap is left between the inner wall of the insulation layer (7) and the container liner (101), which facilitates air flow during cooling and ensures that the insulated container can freely switch between cooling and insulation states. This results in the sixth embodiment of the temperature-controlled insulated container of the present invention.

[0103] Example 6

[0104] like Figures 18 to 20The following is a sixth embodiment of the temperature-controlled insulated container according to the present invention, comprising a container body (1), a container lid (2), a cooling-insulating switching mechanism (3), an upper vent (409), an upper vent sealing ring (410), a lower vent (411), a bottom sealing gasket for the container inner liner (412), and a bottom sealing gasket for the container outer shell (413); the container body (1) includes a container inner liner (101) and a container outer shell (102); the container lid (2) includes a container lid metal outer shell (201), a container lid threaded inner cap (202), and a silicone sealing gasket (203); for the purpose of brief description, any technical features applicable to the same use in any of the above embodiments are described herein, and there is no need to repeat the same description.

[0105] The cooling-heat preservation switching mechanism (3) comprises an upper fixed ring (301), a fastening collar (302), an elastic ring (303), and a lower fixed ring (304); the fastening collar (302) in the cooling-heat preservation switching mechanism (3) has an internal thread, and the lower fixed ring (304) has an external thread. The upper end of the fastening collar (302) protrudes and engages in the groove (309) of the upper fixed ring (301). The internal thread (305) of the fastening collar and the external thread (307) of the lower fixed ring are connected; the cooling-heat preservation switching mechanism (3) and the container shell ( 102) Welded or sealed and bonded into an integral structure; the cooling-insulation switching mechanism (3) is installed at any position on the container shell (102), in this embodiment it is installed at the upper part of the container shell (102) and the lower part of the container cover (2); the container shell (102), the container liner (101) and the cooling-insulation switching mechanism (3) form a non-vacuum insulation interlayer (6); the passive temperature measuring tag (8) is installed in the vacuum insulation interlayer (5) and fixed at any position on the container liner (101), in this embodiment it is installed on the side of the container liner (101).

[0106] Unlike the first to fifth embodiments of the temperature-controlled insulated container of this invention, the non-empty insulation interlayer insulation medium in this embodiment is non-flowing air, or a combined insulation medium containing an insulation layer (7) and non-flowing air.

[0107] When it is necessary to reduce the temperature of the liquid in the heat-insulating container, the tightening ring (302) of the cooling-heat-insulating switching mechanism (3) can be manually or electrically driven to stretch the elastic ring corrugation (306), and the lower fixing ring (304) is connected to pull the bottom of the container shell (102) to move downward; then the upper vent (409) gradually moves away from the upper vent sealing ring (410), and the bottom sealing gasket (413) of the container shell gradually moves away from the bottom sealing gasket (412) of the container liner. After reaching the set position, the upper vent (409) and the lower vent (411) are fully opened. The air density inside the non-vacuum insulation jacket (6) is reduced after being heated by the inner liner (101) of the container, and flows out from the upper air outlet (409); new air is replenished from the lower air inlet (411) to form a chimney effect. At this time, the insulation container is like a thin-walled ordinary container. The heat inside the insulation container is quickly conducted to the outside of the insulation container through the thin wall, and the liquid inside the insulation container drops rapidly. The user brings his mobile phone close to the passive temperature measuring tag (8) to automatically read the temperature and compare it with the set threshold. When the liquid temperature reaches the user's set temperature, the mobile phone issues an alarm.

[0108] The user can manually or electrically drive the fastening ring (302) of the cooling-insulation switching mechanism (3) to compress the elastic ring corrugation (306), and the lower fixing ring (304) connects to the traction container shell (102) to move upward; then the upper vent (409) is gradually closed by the upper vent sealing ring (410), and the bottom sealing gasket (413) of the container shell gradually approaches the bottom sealing gasket (412) of the container liner. After reaching the set position, the upper vent (409) and the lower vent (411) are completely closed. At this time, the heat-insulating container changes from a metal heat-conducting state to a heat-insulating state. In this embodiment, the heat-insulating medium is air, or a combination of air and heat-insulating layer (7). The heat-insulating effect is not as good as the previous five embodiments, but since the container liner (101) can be directly exposed to the flowing air, the internal liquid cools down faster than in the previous five embodiments.

[0109] In summary, in the implementation of the temperature-controlled insulated container of the present invention, the four structures of the container inner liner (101) and the container inner liner heat-conducting metal protrusion structure (401), the container outer shell (102) and the container outer shell heat-conducting metal protrusion structure (402) and the container inner liner protrusion structure (405), and the container outer shell protrusion structure (406) can be combined again to form two combinations: the container inner liner heat-conducting metal protrusion structure (401) and the container outer shell protrusion structure (406), or the container inner liner protrusion structure (405) and the container outer shell heat-conducting metal protrusion structure (402); or whether or not it contains a container inner liner high heat conduction heat dissipation seat (403) and a container outer shell high heat conduction heat dissipation seat (404), etc. It can also be modified into various embodiments according to different cross-sections or corrugated shapes, or connection methods, or the working mode of the cooling-heat preservation switching mechanism (3), or the working position of the cooling-heat preservation switching mechanism (3), etc.

[0110] In implementation, in the fourth to fifth embodiments of the temperature-controlled heat-insulating container of the present invention, a movable heat-conducting metal protrusion structure (402) is added to the high thermal conductivity heat dissipation base (404) of the container shell, which is welded or sealed and bonded to the high thermal conductivity heat dissipation base (404) of the container shell. This structure can move up and down together with the high thermal conductivity heat dissipation base (404) of the container shell and connect or disconnect with the corresponding heat-conducting metal protrusion structure (401) of the container liner, thereby realizing the switching of the heat-insulating container between the cooling state and the heat-insulating state.

[0111] In practice, the sixth embodiment of the temperature-controlled insulated container of the present invention can be combined into various embodiments depending on the method of sealing the upper air outlet (409) and the lower air inlet (411), or the different positions of the upper air outlet (409) and the lower air inlet (411), or the use of air insulation, air and insulation layer (7) insulation, or other methods.

[0112] In addition, this temperature-controlled insulated container can be given more features, such as continuous graduations on the upper fixing ring (301) and indicator graduations on the fastening ring (302). The indicator graduations correspond to the "0" point on the upper fixing ring (301) for the insulation state and the "10" point for the fully conductive metal state. Of course, other corresponding methods can also be adopted to make it easier for users to become familiar with the different states of the insulated container.

[0113] To prevent the inner liner protrusion structure (405) and the outer shell protrusion structure (406) from connecting, a very small number of point-like or ring-shaped heat-insulating ceramic or heat-insulating material supports can be provided in the vacuum layer to ensure the vacuum gap between the inner liner protrusion structure (405) and the outer shell protrusion structure (406). To control the axial deformation of the inner liner (101) and the outer shell (102), longitudinal reinforcing ribs (407) are added to one or both sides of the inner liner (101), and longitudinal reinforcing ribs (408) are added to one or both sides of the outer shell (102). The number of the reinforcing ribs is selected to be an even number of four or more.

[0114] To protect user safety and prevent burns, a decorative heat-resistant protective sleeve (9) made of plastic, silicone, leather, or other heat-insulating materials is provided on the outside of the container shell (102). The heat-resistant protective sleeve (9) has evenly spaced heat dissipation holes (10), which correspond to the recessed parts of the container shell (102) (which are also the protruding structures of the container shell (102) within the vacuum insulation layer (5)). A temperature-sensing strip can also be provided on the heat-resistant protective sleeve (9), which can display different colors according to the water temperature. Users can directly perceive the temperature of the liquid inside the container based on the different colors of the temperature-sensing strip.

[0115] The container body (1) can be constructed using non-metallic materials, metallic materials, or a combination of non-metallic and metallic materials. Depending on the function, role, and market demand of the inner liner (101) and outer shell (102), the same or different materials can be used, for example: ① Metallic materials, including stainless steel, aluminum and aluminum alloys, copper, tin, gold, titanium, zinc alloys, cast iron, pig iron, etc.; ② Ceramic materials, including ceramics, stoneware, purple clay, enamel, maifan stone, glass, etc.; ③ Glass materials, including ordinary soda-lime glass, borosilicate glass, tempered glass, crystal glass, quartz glass, frosted glass, double-glazed glass, etc.; ④ Plastic resin materials, including polypropylene (PP), copolyester (Trtan), polycarbonate (PC), polyethylene (PE), etc. The materials used in the temperature-controlled insulated container of this invention can be any one of the above-mentioned commonly used materials, or different species within the same category, or different species within different categories. They can be arbitrarily combined among different material types according to different functions and market demands, without restriction. Other materials include: ⑤ natural stone materials, such as maifan stone, obsidian, marble, granite, bian stone, and raw crystal; ⑥ wood / bamboo materials, such as solid wood, bamboo, carbonized bamboo, and cork; ⑦ animal-derived materials, including ox horns, ram horns, shells, and conches; ⑧ paper / plant fiber materials, including paper cups, bamboo fiber cups, pulp molding compounds, and biodegradable plant fibers; and ⑨ composite materials with special functions, including vacuum-plated copper / silver-plated insulation materials, aerogel insulation materials, ceramic-coated metal, and graphene-coated thermally conductive metal.

[0116] This invention also includes a temperature control method for insulated containers, comprising the following steps:

[0117] S1: Switch the container to cooling mode and inject high-temperature liquid;

[0118] S2: Temperature control structure (4) rapidly reduces the temperature of high-temperature liquids through solid heat conduction;

[0119] S3: Passive temperature measurement tag (8) continuously collects temperature;

[0120] S4: The phone is brought close to the tag to read the temperature and compare it with a set threshold.

[0121] S5: The phone issues a warning when the liquid temperature reaches the target level;

[0122] S6: The user can manually or electrically switch the container to the heat preservation state.

[0123] The advantages of this invention are: (1) completely passive: no electricity, no battery, no phase change material, no liquid flow; (2) rapid cooling: 100℃ boiling water is cooled to a suitable drinking temperature in 10-20 minutes; (3) accurate temperature measurement: passive NFC temperature measurement with an error of ≤±0.3℃; (4) intelligent reminder: automatic warning from mobile phone, no need to open the lid to test the temperature; (5) one-button switching: cooling-heating switching mechanism is mechanically switched, and the operation is simple; (6) safe and hygienic: no water spillage, no water mixing, no material precipitation; (7) long service life: no aging parts, and stable and reliable structure.
