[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0045] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a heat preservation container, which includes a container body 1 and a heating plug 2. The top of the container body 1 is provided with a container mouth 11, so that the user can store and take out articles; the heating plug 2 is used to convert electrical energy into thermal energy, thereby releasing heat into the container body 1, increasing the internal temperature of the container body 1, and playing a role in heat preservation or heating the articles in the container body 1; the heating plug 2 passes through the container mouth 11 and is installed in the container body 1, so that the heating plug 2 releases heat inside the container body 1 to reduce heat loss. The heating plug 2 can slide along the axial direction of the container body 1, and the user can adjust the position of the heating plug 2 in the container body 1 according to the amount of articles contained in the container body 1, so as to reduce the interval between the articles and the heating plug 2, so that the heating plug 2 can be heated as close to the articles as possible, and improve the heat preservation and heating effect. In addition, as the articles or gas in the container body 1 expand and contract, the heating plug 2 can also automatically slide in the container body 1, so as to adjust the size of the space between the heating plug 2 and the container body 1, balance the internal and external air pressure, and prevent the pressure in the container body 1 from being too high and causing danger.

[0046] Specifically, the cross section of the heating plug 2 is not larger than the cross section of the container mouth 11, so that the heating plug 2 can completely pass through the container mouth 11 and be accommodated in the interior of the container body 1. Within the sliding stroke of the heating plug 2, the cross section of the heating plug 2 is not larger than the cross section of the interior of the container body 1, so that the heating plug 2 can slide freely in the interior of the container body 1.

[0047] In one embodiment, when the heating plug 2 is at the highest position of the sliding stroke, the top of the heating plug 2 can be higher than the top of the container body 1. At this time, a portion of the heating plug 2 extends out of the container mouth 11 to reduce the space occupied by the heating plug 2 in the container body 1 and increase the maximum available volume of the container body 1.

[0048] In another embodiment, when the heating plug 2 is at the highest position of the sliding stroke, the top of the heating plug 2 is not higher than the top of the container body 1. At this time, the heating plug 2 is completely located inside the container body 1 to ensure the matching length between the heating plug 2 and the container body 1, thereby ensuring that the heating plug 2 is reliably installed in the container body 1 and preventing the heating plug 2 from falling from the container mouth 11 due to external collision or internal steam pressure.

[0049] Furthermore, the interior of the container body 1 includes a uniform cross-sectional segment 12, which extends axially along the container body 1. The cross-sectional area (including shape and size, etc.) of the uniform cross-sectional segment 12 remains unchanged. The heating plug 2 is installed on the uniform cross-sectional segment 12 and slides along the uniform cross-sectional segment 12. The uniform cross-sectional segment 12 guides the heating plug 2 to ensure that the matching state of the heating plug 2 and the container body 1 remains unchanged within the movement range of the heating plug 2, thereby preventing the heating plug 2 from shifting or tilting unexpectedly, which would cause heat loss in the container body 1.

[0050] Further, the top of the uniform cross-sectional section 12 is aligned with the top of the container body 1, that is, the uniform cross-sectional section 12 extends downward from the container mouth 11, and the cross section of the uniform cross-sectional section 12 is the same as the cross section of the container mouth 11, so as to reduce the length requirement of the heating plug 2 extending into the container body 1, and increase the highest position of the bottom of the heating plug 2 as much as possible, thereby reducing the space occupied by the heating plug 2 in the container body 1, and thus increasing the maximum available volume of the container body 1. It can be understood that in other embodiments, the top of the uniform cross-sectional section 12 can also be lower than the top of the container body 1, that is, there is a gap between the uniform cross-sectional section 12 and the container mouth 11, so as to increase the length of the heating plug 2 extending into the container body 1 and prevent the heating plug 2 from falling from the container mouth 11.

[0051] Furthermore, the heat-insulating container further comprises a protective cover 3, which is detachably connected to the top of the container body 1. For example, the protective cover 3 and the container body 1 can be connected to each other by means of a threaded structure or a snap-fit ​​structure. The heating plug 2 is located in the space enclosed by the protective cover 3 and the container body 1, which can not only play an axial limiting role for the heating plug 2, limiting the highest sliding position of the heating plug 2 in the container body 1, effectively preventing the heating plug 2 from falling out of the container body 1 during use, but also play a protective role around the circumference of the heating plug 2, preventing the heating plug 2 from being tilted or shifted by external forces during use, thereby affecting the heat preservation and heating effect of the heat-insulating container.

[0052] Specifically, the protective cover 3 includes a side portion and an end portion connected to each other. The side portion extends along the axial direction of the container body 1 and is used to connect the side wall of the container body 1, so as to achieve the installation and fixation of the protective cover 3; at least a part of the end portion extends to the top of the heating plug 2, so as to play a role of stopping and limiting above the heating plug 2.

[0053] In one embodiment, the side and the end form a closed cavity structure with an opening facing downward, that is, the protective cover 3 completely closes the container opening 11, which can not only increase the appearance of the thermal insulation container, but also play a role in dust prevention and heat insulation, thereby further improving the user experience of the thermal insulation container. Of course, in other embodiments, the side and the end can also form a frame structure or a mesh structure, that is, the protective cover 3 blocks a part of the container opening 11, as long as it can play an axial limiting role on the heating plug 2.

[0054] Furthermore, a sealing ring 4 is sleeved on the outer periphery of the heating plug 2, and the sealing ring 4 elastically presses against the inner wall of the container body 1. On the one hand, a sealing fit is formed between the heating plug 2 and the container body 1, and convection exchange between the hot air in the container body 1 and the cold air outside is avoided, thereby reducing the heat loss in the container body 1 and improving the heat preservation effect; on the other hand, the sealing ring 4 plays a damping role between the heating plug 2 and the container body 1, increasing the sliding resistance of the heating plug 2, so that the heating plug 2 can stay stably at a predetermined position, reducing the movement or shaking of the heating plug 2 during use, thereby ensuring reliable heat preservation and heating effects.

[0055] Furthermore, a gripping portion 214 is provided on the top of the heating plug 2 to facilitate the user to lift the heating plug 2 and put the heating plug 2 into or take it out of the container body 1. The gripping portion 214 can be configured as any appropriate protruding structure, such as a columnar, strip-shaped, block-shaped or hook-shaped structure, as long as it can be conveniently pinched by the user's fingers.

[0056] Furthermore, the gripping portion 214 is configured as a strip-shaped structure extending along the surface of the heating plug 2. On the one hand, the area of ​​the gripping portion 214 can be increased within a limited operating space, thereby increasing the stability of the user in lifting the heating plug 2; on the other hand, it can prevent the heating plug 2 from slipping off due to the rotation of the user's fingers when the user lifts the heating plug 2. In addition, the strip-shaped structure provided on the top of the heating plug 2 can also play a reinforcing role, increase the overall structural strength of the heating plug 2, and reduce the risk of deformation or damage of the heating plug 2.

[0057] Furthermore, a groove 215 is provided on the top of the heating plug 2, and the gripping portion 214 is protruded in the groove 215. Without increasing the overall height of the heating plug 2, the effective height of the gripping portion 214 is increased, thereby increasing the stability of the user in lifting the heating plug 2 and preventing the heating plug 2 from accidentally slipping off.

[0058] Furthermore, the heating plug 2 includes a shell 21 and an electric heating element 22. The shell 21 is slidably matched with the container body 1, and the shell 21 has an installation cavity 213 inside, and the electric heating element 22 is arranged in the installation cavity 213. The electric heating element 22 is used to convert electrical energy into thermal energy, and the shell 21 plays a protective role to prevent the internal electric heating element 22 and other components from being damaged. The shell 21 can adopt an integral molding structure, or a structure in which at least two parts are connected to each other.

[0059] Furthermore, the housing 21 includes a heat-insulating shell 211 and a heat-conducting shell 212 connected to each other, the heat-conducting shell 212 is sealed and connected to the bottom of the heat-insulating shell 211, and a mounting cavity 213 is formed between the heat-conducting shell 212 and the heat-insulating shell 211. The heat of the electric heating element 22 is transferred and released into the container body 1 through the lower heat-conducting shell 212 to increase the heat dissipation area and improve the heating effect; the upper heat-insulating shell 211 plays a role of heat insulation, preventing the heat of the electric heating element 22 from being transferred upward and released to the external air, thereby improving the utilization rate of heat.

[0060] Furthermore, the heating plug 2 also includes a control module 23 (for example, a PCB board, etc.), the control module 23 is arranged in the installation cavity 213, the control module 23 is electrically connected to the electric heating element 22, and the control module 23 is used to control the electric heating element 22 to start heating or stop heating, which can not only improve the heat utilization rate and extend the insulation time of the insulation container, but also improve the safety of the use of the insulation container, and prevent the temperature in the container body 1 from being too high, resulting in scalding the user or easy damage to the insulation.

[0061] Furthermore, the control module 23 and the heat-conducting shell 212 can be interconnected through a thermoelectric conversion module, etc. The control module 23 is used to control the electric heating element 22 to start or stop heating according to the temperature feedback of the heat-conducting shell 212. That is to say, the heat-conducting shell 212 detects the temperature inside the container body 1 and feeds back the temperature information to the control module 23. There is no need to set a separate temperature sensing probe on the heating plug 2, which can simplify the overall structure and reduce production costs, and can also improve the appearance and integrity of the heating plug 2.

[0062] Furthermore, the heating plug 2 also includes a power module 24, which is arranged in the installation cavity 213. The power module 24 has a power storage function. The control module 23 is used to control the power on and off of the power module 24. The power module 24 is used to provide electrical energy to the electric heating element 22, so that the heating plug 2 does not need to be connected to an external power supply. It can independently realize the heating function, thereby improving the convenience of using the thermal insulation container.

[0063] Furthermore, the power module 24 includes a rechargeable battery, and the housing 21 is provided with a charging port 25 (for example, a USB port or a type-C port, etc.), and the charging port 25 is electrically connected to the power module 24, so that the power of the power module 24 can be supplemented by an external power source to achieve the recycling of the heating plug 2. It can be understood that the power module 24 can also include a non-rechargeable battery, and the heating plug 2 can be recycled by replacing the battery.

[0064] Furthermore, the heating plug 2 also includes an operating module 26 (for example, a touch screen or a button, etc.), at least a portion of the operating module 26 is exposed outside the shell 21, the operating module 26 is electrically connected to the control module 23, and the operating module 26 is used to set the heating mode to meet the user's different heating and insulation requirements.

[0065] Furthermore, the control module may include a timing module, and the heating mode includes a timing heating mode, so that the user can accurately control the heating time. The timing heating mode may specifically include: the user sets the start heating time point and the heating duration; when the timing reaches the set start heating time point, the heating plug 2 starts heating; and the heating plug 2 stops heating after heating for a predetermined heating duration.

[0066] The control module may include a constant temperature module, and the heating mode includes a constant temperature heating mode, so that the user can accurately control the heating temperature. The constant temperature heating module may specifically include: the user sets the upper temperature limit and the lower temperature limit; the heat-conducting shell 212 of the heating plug 2 detects the temperature in the container body 1; when the temperature in the container body 1 is lower than the lower temperature limit, the heating plug 2 starts heating; when the temperature in the container body 1 is higher than the upper temperature limit, the heating plug 2 stops heating.

[0067] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
