Description

Technical Field

[0001] This utility model relates to the field of insulated bowls, and more particularly to a water-filled insulated bowl. Background Technology

[0002] Water-filled insulated bowls are tableware that uses hot or cold water injected between the inner and outer bowl layers to keep food warm or cool. They are widely used in infant feeding, medical care, and daily family meals. Water-filled insulated bowls typically use a hollow structure between the two bowls as a water-filling cavity to enhance the heat exchange between food and liquid.

[0003] In existing technologies, to prevent burns caused by excessively high outer wall temperatures during use, some insulated bowls have an insulated chamber outside the water filling cavity to improve safety. However, the insulated chamber is usually filled with air, which has limited insulation performance. Heat can still be conducted to the outside of the bowl through the air layer, thus affecting the insulation performance. In addition, the inner and outer bowls of existing insulated bowls are generally connected by mechanical snap-fit, which is easy to assemble but has poor sealing performance and is prone to leakage at the connection, thus affecting the thermal insulation performance and reliability of the water-filled insulated bowl.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0007] The inner bowl is disposed inside the outer bowl, and the top of the inner bowl is seamlessly connected to the top of the outer bowl, so that a sealed cavity is formed between the inner bowl and the outer bowl;

[0008] The bottom of the outer bowl is provided with a through hole, and the one-way air extraction valve is located in the through hole. The one-way air extraction valve is used to evacuate the sealed cavity so that the sealed cavity forms a vacuum environment.

[0009] The top of the inner bowl has an external thread structure, the top periphery of the heat-insulating inner liner is provided with a first stop edge, and the inner top wall of the threaded locking sleeve is provided with a limiting step. The limiting step is used to press the first stop edge against the upper end face of the inner bowl when the threaded locking sleeve is threadedly connected to the external thread structure.

[0010] A water-filling cavity is formed between the insulated inner liner and the inner bowl;

[0011] The bowl lid is sealed over the opening of the insulated inner liner.

[0012] The water-filled heat-insulating bowl, which adopts the above technical solution, also includes a sealing ring, a second retaining edge is formed around the periphery of the sealing ring, and the sealing ring is provided with an upwardly protruding annular boss;

[0013] The second baffle is attached between the first baffle and the upper surface of the inner bowl. The top periphery of the heat-insulating inner liner is provided with an annular groove, and the annular boss is embedded and engaged with the annular groove.

[0014] Using the above technical solution, in the water-filled heat-insulating bowl, the bottom of the outer bowl is provided with a stepped groove, the through hole is located in the stepped groove, and the stepped groove is used to accommodate the one-way air extraction valve.

[0015] The above technical solution includes a sealing plug in the water-filled heat-insulating bowl. The sealing plug is located in the stepped groove and is used to block and isolate the one-way air extraction valve.

[0016] Using the above technical solution, the water-filled insulated bowl has a lid with a lifting lug, which is used to open the lid by applying force with a finger.

[0017] Using the above technical solution, in the water-filled heat-insulating bowl, the top of the inner bowl and the top of the outer bowl are seamlessly connected by heat fusion, adhesive coating, laser welding or ultrasonic welding.

[0019] In the above technical solution, the outer wall of the threaded locking sleeve in the water-filled heat-insulating bowl is provided with a handle.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention places the inner bowl inside the outer bowl, and the two are seamlessly connected to form a sealed cavity. The bottom of the outer bowl is equipped with a one-way vacuum valve, which can perform vacuum treatment on the sealed cavity to reduce the heat conduction efficiency of the heat-insulating bowl, thereby enhancing the heat insulation performance. The top of the inner bowl is equipped with an external thread structure, and the top of the heat-insulating inner liner is equipped with a first baffle. When the threaded locking sleeve is tightened, the limiting step on its inner top wall can press the first baffle and the sealing ring tightly against the upper end face of the inner bowl.

[0032] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 7 As shown, this utility model embodiment provides a water-filled insulated bowl, including an outer bowl 1, an inner bowl 2, an insulated inner liner 3, a threaded locking sleeve 4, a one-way air extraction valve 5, and a bowl lid 6; the inner bowl 2 is disposed inside the outer bowl 1, and the top of the inner bowl 2 is seamlessly connected to the top of the outer bowl 1 to form a sealed cavity 101 between the inner bowl 2 and the outer bowl 1; the bottom of the outer bowl 1 is provided with a through hole 10, and the one-way air extraction valve 5 is disposed in the through hole 10. The one-way air extraction valve 5 is used for... The sealed cavity 101 is evacuated to create a vacuum environment. By providing a through hole 10 at the bottom of the outer bowl 1 and installing a one-way vacuum valve 5 at the through hole 10, the sealed cavity 101 can be evacuated after product assembly, allowing the air inside to be expelled and creating a stable negative pressure environment. This effectively reduces heat conduction within the sealed cavity 101 and enhances the heat insulation performance of the insulated bowl, thus maintaining food temperature for a longer period. It should be noted that in this embodiment, both the outer bowl 1 and the inner bowl 2 are made of plastic.

[0035] The inner bowl 2 has an external thread structure 21 at its top, and the top periphery of the insulated inner liner 3 is provided with a first retaining edge 31. The inner top wall of the threaded locking sleeve 4 is provided with a limiting step 41. The limiting step 41 is used to press the first retaining edge 31 against the upper end face of the inner bowl 2 when the threaded locking sleeve 4 is threadedly connected to the external thread structure 21. A water injection cavity 102 is formed between the insulated inner liner 3 and the inner bowl 2. When the threaded locking sleeve 4 is screwed onto the external thread structure 21 at the top of the inner bowl 2, the limiting step 41 is gradually pressed down and abuts against the first retaining edge 31 of the insulated inner liner 3, thereby firmly pressing the first retaining edge 31 against the upper end face of the inner bowl 2, realizing a close contact between the insulated inner liner 3 and the inner bowl 2, thereby improving the assembly structure stability of the insulated inner liner 3 and preventing it from shaking during use.

[0036] The bowl lid 6 is sealed over the opening of the heat-insulating inner liner 3. By setting the bowl lid 6 at the opening of the heat-insulating inner liner 3, not only can the internal heat be effectively blocked from convection and conduction to the outside, but also dust and foreign objects can be effectively prevented from entering the heat-insulating inner liner 3, thereby improving the hygiene and safety of food.

[0037] like Figures 2 to 4 As shown, it further includes a sealing ring 7, the sealing ring 7 having a second retaining edge 71 formed around its periphery, and the sealing ring 7 having an upwardly protruding annular boss 72. The second retaining edge 71 is attached between the first retaining edge 31 and the upper end face of the inner bowl 2. The top periphery of the heat-insulating inner liner 3 has an annular groove 32, and the annular boss 72 and the annular groove 32 are embedded and engaged. During assembly, the second retaining edge 71 is located between the first retaining edge 31 and the upper end face of the inner bowl 2, and can form an axial pressing surface under the tightening action of the threaded locking sleeve 4, thereby effectively improving the sealing performance between the heat-insulating inner liner 3 and the inner bowl 2 and preventing liquid from leaking out through the connection interface.

[0038] like Figure 5 As shown, the outer bowl 1 is further provided with a stepped groove 11 at the bottom, and the through hole 10 is located in the stepped groove 11. The stepped groove 11 is used to accommodate the one-way air extraction valve 5, so that the one-way air extraction valve 5 is in a recessed state, preventing it from being exposed at the bottom of the bowl, thereby preventing it from being accidentally touched during use and causing vacuum failure.

[0039] like Figure 2 and Figure 5 As shown, it further includes a sealing plug 8, which is disposed in the stepped groove 11. The sealing plug 8 is used to block and isolate the one-way air extraction valve 5, thereby covering and shielding the one-way air extraction valve 5 after the air extraction is completed, achieving physical isolation and thus enhancing the overall safety of use.

[0040] like Figure 1 As shown, the bowl lid 6 is further provided with a lifting lug 61, which is used to open the bowl lid 6 by applying force with a finger. By providing a lifting lug 61 on the bowl lid 6, the user can easily open the bowl lid 6 by hooking the part with their finger, thereby improving the user experience of the product.

[0041] Furthermore, the top of the inner bowl 2 and the top of the outer bowl 1 are seamlessly connected by heat fusion, adhesive coating, laser welding or ultrasonic welding. In this embodiment, the top of the inner bowl 2 and the top of the outer bowl 1 are seamlessly connected by adhesive coating to form an integrated connection interface, avoiding the air leakage problem caused by assembly tolerance in the traditional mechanical snap-fit ​​method, and improving the sealing and heat insulation performance of the heat preservation bowl.

[0042] like Figure 6As shown, furthermore, the inner bowl 2 has several rib structures 22 on its wall surface. The rib structures 22 can not only improve the structural strength of the inner bowl 2 and prevent the inner bowl 2 from deforming due to the pressure difference or temperature change between the inside and outside during the process of water injection and heating, but also provide a certain friction force so as to fully grind food such as apples, thus expanding the use function of the insulated bowl.

[0043] like Figure 1 As shown, the outer wall of the threaded locking sleeve 4 is provided with a handle 42. This design makes it easier for the user to apply rotational force, thereby improving the convenience of assembly and disassembly.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
