[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0029] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0030] See attached Figure 1-6The present embodiment discloses an insulation bowl, comprising an outer shell 10 and an inner liner 20. The outer shell 10 is sleeved on the outside of the inner liner 20 and an interlayer 30 is formed between the outer shell 10 and the inner liner 20. The outer shell 10 and the inner liner 20 are two independent components, which are assembled into one body when in use. Among them, the inner liner 20 can be made of food-grade stainless steel, so that the inner liner 20 has good thermal conductivity, which is convenient for cold water or hot water injected into the interlayer 30 to cool or keep warm the food in the inner liner 20. The outer shell 10 can be made of plastic material, so that the outer shell 10 is not easy to conduct heat, which not only helps to avoid heat loss in the interlayer 30, but also can avoid scalding the user when hot water is injected into the interlayer 30. In this embodiment, a sealing member 40 for sealing the interlayer 30 is provided between the inner liner 20 and the outer shell 10. By providing the sealing member 40 between the outer shell 10 and the inner liner 20, the heat loss of the liquid in the interlayer 30 can be reduced and the outflow of the liquid in the interlayer 30 can be avoided, and the traditional threaded sealing structure is abandoned. After hot water is injected into the interlayer 30, the inner liner 20 may be lifted up under the air pressure of the hot water, causing the seal to loosen. By providing a movable locking member 11 on the outer shell 10, the locking member 11 can be set as a plastic member or a metal member during design. Driving the locking member 11 to move can lock the inner liner 20 on the outer shell 10. The locking member 11 can not only limit the position of the inner liner 20, but also apply a certain extrusion force to the sealing member 40 through the inner liner 20 to ensure the safety of use and the sealing effect. When disassembly is required or the water temperature in the interlayer 30 is reduced, the user can control the locking member 11 to move and disengage from the position of the inner liner 20 to release the lock of the inner liner 20.

[0031] When the thermal insulation bowl of the present invention is in use, the inner liner 20 is first taken out of the outer shell 10, and then cold water or hot water is added into the outer shell 10. Then the inner liner 20 is placed into the outer shell 10, and the bottom of the inner liner 20 is immersed in the cold water or hot water in the interlayer 30. Food can be placed inside the inner liner 20. The seal 40 is squeezed by pressing the inner liner 20 under the action of the gravity of the inner liner 20 and the food therein, and the seal 40 is deformed. At the same time, the position of the inner liner 20 is fixed by the interaction force. The position of the inner liner 20 is secondarily limited by setting the locking member 11 to ensure the stability of the inner liner 20 and the sealing effect of the interlayer 30.

[0032] See attached Figure 4 , 6The locking member 11 of one embodiment of the utility model includes a locking portion 111 and a connecting portion 112, wherein the connecting portion 112 is connected to the outer shell, and the locking portion 111 is constructed as a buckle protruding from a side wall of the connecting portion. In this embodiment, the inner liner 20 is locked by a buckle structure, which makes the operation more convenient and improves the user experience. Of course, in actual settings, the cooperation between the locking member 11 and the inner liner 20 is not limited to a buckle fit, and can also be set to a press fit (one end of the locking member 11 is pressed against the side wall or end face of the inner liner 20 to lock the inner liner 20), a plug-in fit (a plug-in hole is opened on the inner liner 20, and one end of the locking member 11 is removed into the plug-in hole) or other easily conceivable matching structures.

[0033] When the locking member 11 is used in conjunction with the inner container 20, see the attached Figure 1 , 2 3. The outer wall of the inner liner 20 is generally formed with a protruding curling edge 21, which is located below the opening end of the inner liner 20. When the insulation bowl is installed, the curling edge 21 of the inner liner 20 is stuck at the upper edge of the outer shell 10 and protrudes from the opening edge of the outer shell 10. The locking position of the locking member 11 is lower than the opening of the inner liner 20. By designing the size of the locking member 11, the locking part 111 is buckled on the curling edge 21 to lock the inner liner 20. Under the premise of ensuring the strength of the locking member 11, the top of the locking member 11 is made lower than the upper opening of the inner liner 20, so that the locking member 11 can be prevented from protruding from the opening end of the inner liner 20 when the insulation bowl is used, thereby improving the user experience.

[0034] The inner liner 20 of the utility model is sleeved in the outer shell 10, and the curling edge 21 cooperates with the upper opening edge of the outer shell 10. When installing, the user can press the inner liner 20 to apply a certain pre-pressure to the inner liner 20, and then snap the locking part 111 of the locking member 11 at the curling edge 21 position of the inner liner 20. As the user removes the pressing force, the elastic member between the inner liner 20 and the outer shell 10 will produce elastic deformation, and the air pressure of the hot water in the interlayer 30 will cause the inner liner 20 to have an upward movement trend. Due to the design of the locking member 11, the inner liner 20 can be prevented from moving upward, so that the sealing member 40 can be kept in a compressed state, thereby improving the sealing effect. Of course, it is conceivable that in order to ensure that the locking member 11 can be smoothly snapped on the upper end or upper part of the curling edge 21, a smooth transition groove can be opened at the end of the locking member 111 to play a guiding effect. Of course, in some cases, the locking member 111 can also be set as an adjustable structure so that it can adapt to the locking requirements of different positions of the inner liner 20 and can adjust the locking force.

[0035] It can be imagined that in order to improve the locking effect, a slot can be provided on the upper end surface of the locking edge of the inner liner 20, and a hook structure that cooperates with the slot can be provided at the end position of the locking portion 111 of the locking piece 11. In this way, when the locking piece 11 is buckled on the inner liner 20, the hook head is extended into the slot. This can improve the stability of the locking piece 11 when locking, and avoid the problem of the locking piece 11 being separated from the inner liner 20 and unable to lock due to shaking during use. It should be noted that the cooperation between the hook head and the slot here will not affect the user's active release of the lock of the locking piece 11 and the inner liner 20.

[0036] In one embodiment of the present invention, the locking member 11 is rotatably connected to the housing 10 via the connecting portion 112. The user manipulates the locking member 11 to rotate so that it switches between a locked state (a position for locking the inner liner 20) and an unlocked state (a position for unlocking the inner liner 20). Of course, it is conceivable that in actual settings, the locking member 11 can also be set as a sliding structure or a combination of sliding and rotating structures.

[0037] See attached Figure 3 , 4 The sealing ring in the utility model can be a food-grade silicone sealing ring with elasticity. There are two forms of the setting position of the sealing member 40: first, the sealing member 40 is set on the inner liner 20, in which case the sealing member 40 can be set at the lower end of the curling edge 21 of the inner liner 20, and specifically, a mounting groove for mounting the sealing member 40 can be opened at the lower end of the curling edge 21 of the inner liner 20, and then the sealing member 40 is embedded in the mounting groove; second, the sealing member 40 is set on the outer shell 10, in which case the sealing member 40 can be installed at the upper end opening of the outer shell 10, and specifically, a mounting groove can be set at the opening edge of the outer shell 10, and the sealing member 40 is embedded in the mounting groove, or the sealing member 40 is directly fixed at the opening near the outer shell 10 by bonding or clamping.

[0038] In order to improve the stability of the insulation bowl during use, see the attached Figure 1 , 2 The outer wall of the shell 10 of the utility model is provided with symmetrically arranged handles 12, and each handle 12 is provided with a locking member 11. The present embodiment is provided with two symmetrically arranged locking members 11. When in use, the two locking members 11 simultaneously lock the inner liner 20, and can apply symmetrical locking forces to the inner liner 20, so that the locking forces on the inner liner 20 are balanced, thereby improving stability. It is conceivable that the number of handles 12 is not limited to two, and can also be set to three, four or more circumferential distributions. In addition, it is conceivable that the handle 12 and the shell 10 can be set as an integrally formed structure, or can be set as a structure assembled to each other.

[0039] In addition, it should be noted that the locking member 11 is arranged on the handle 12 is only a preferred embodiment of the present invention. In actual setting, the locking member 11 can be directly arranged on the housing 10. Specifically, the locking member 11 can be arranged in the interval area between the two handles 12.

[0040] See attached Figure 3 , 4 5. In order to improve the user experience, the handle 12 of the utility model is provided with a recessed mounting portion 121, and the locking member 11 is installed on the mounting portion 121. The rotation of the locking member 11 can make the locking portion 111 extend out of or retract into the mounting portion 121. In the non-locking state, the locking member 11 can be kept in the mounting portion 121. When the inner liner 20 needs to be locked, the locking member 11 can be rotated at this time to make the locking portion 111 of the locking member 11 extend out of the mounting portion 121. When not in use, the locking member 11 can be stored in the mounting portion 121, and a hidden design is performed to improve the overall appearance. Among them, in the specific design, the mounting portion 121 can be set as a through hole or groove that passes through the handle 12, preferably a through hole structure, so that impurities can be reduced in the mounting portion 121. In addition, the thickness of the locking member 11 is designed to be less than the thickness of the handle 12 or the depth of the groove, so that the locking member 11 can be completely placed in the mounting portion 121.

[0041] Of course, it is conceivable that the specific position of the locking member 11 on the handle 12 can be set according to actual conditions, and can be set on the front side of the handle 12, or on the side of the handle 12, or even on the bottom side of the handle 12. In some embodiments, the handle 12 can also be set as a movable structure, so that it can be used as the locking member 11 or as the handle 12, further simplifying the overall structure.

[0042] In order to improve the stability of the locking member 11 during the activity and to provide the user with a better operating feel, the locking member 11 of the utility model is rotatably connected to the inner wall of the mounting portion 121 through a pin 13, and the pin 13 is arranged on one of the locking member 11 or the handle 12, and is connected to the damping shaft of the other. In this way, when the locking member 11 is manipulated to move, it is convenient to control the position of the locking member 11 so that it can be stably maintained at the position after the activity, so that when the locking member 11 is stored, the shaking of the locking member 11 caused during the movement can be avoided. Of course, it is conceivable that a magnetically adsorbed component can also be arranged on the locking member 11 and the handle 12 to fix the locking member 11. In addition, a torsion spring or a spring can be arranged at the connection position of the pin 13, so that the locking member 11 can automatically remain at a certain position in the non-locking state by relying on the elasticity of the torsion spring or the spring. Of course, in actual design, the position of the locking member 11 may not be fixed.

[0043] During the use of the insulation bowl, as the water temperature decreases, negative pressure may exist between the outer shell 10 and the inner liner 20, making it difficult to disassemble and open. The utility model provides a pressure relief hole connected to the interlayer 30 on the outer shell 10, and a relief valve 14 is provided in the pressure relief hole. The relief valve 14 can close the pressure relief hole when the air pressure in the interlayer 30 is greater than the external air pressure; the relief valve 14 can also open the pressure relief hole when the air pressure in the interlayer 30 is lower than the external air pressure. In actual settings, by setting the structure of the relief valve 14, the relief valve 14 and the pressure relief hole of the utility model can automatically exhaust the interlayer 30 without manual operation by the user, so that when the insulation bowl is in use, the liquid in the interlayer 30 will not generate negative pressure after cooling, which facilitates the disassembly of the inner liner 20 and the outer shell 10.

[0044] See attached Figure 1 The insulation bowl of the present invention also includes a cover body 50 and a detachable suction cup 60. The cover body 50 is buckled on the open end of the inner liner 20. A sealing ring can also be provided on the cover body 50 to keep the inner liner 20 warm. In addition, an air hole 51 is provided on the cover body 50 and a valve body is provided in the air hole 51, which plays the role of the above-mentioned pressure relief valve and pressure relief hole, avoiding the problem of being unable to open the cover body 50 due to negative pressure. The detachable suction cup 60 of the present invention is arranged at the bottom of the outer shell 10 and can adsorb and fix the outer shell 10, thereby improving the stability of the insulation bowl during use.

[0045] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
