Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, specifically relating to a vacuum-sealed cookware. Background Technology

[0002] In daily life, preserving leftovers or food is a common practice. People usually use plastic wrap or food storage containers to wrap the food and then put it in the refrigerator. However, the preservation time is short and the food is prone to spoilage. As a result, appliances with vacuum pumps have emerged to extend the preservation time by vacuum sealing the food. However, the vacuum pump of such appliances is integrated with the food container, making it inflexible and difficult to use. Furthermore, if the vacuum pump malfunctions, disassembly and assembly are extremely inconvenient, and the entire appliance becomes unusable, causing great inconvenience to users. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides a vacuum-sealed cookware, aiming to solve the problem of inconvenience caused by the integrated connection of the vacuum pump and the cookware in the prior art.

[0005] (2) Technical solution

[0006] This utility model provides a vacuum-sealed cookware, including a detachably connected lid and a pot body. The lid is provided with an exhaust port, and a seal that can move up and down is installed inside the exhaust port. An air gap communicating with the interior of the pot body is provided between the seal and the peripheral wall of the exhaust port. The seal is provided with a first abutting part, which movably and sealingly abuts against the upper end face of the peripheral wall of the exhaust port.

[0007] When a vacuum pump is connected to the sealing element for evacuation, the upper end of the sealing element is under negative pressure and moves upward as a whole, causing the first contact part to separate from the upper end face of the peripheral wall of the exhaust port and form an opening communicating with the air gap. The air inside the pot is discharged to the outside through the air gap and the opening in sequence.

[0008] After the evacuation is completed, the vacuum pump is disconnected from the seal. The lower end of the seal is under negative pressure and moves downward as a whole, so that the first abutting part seals against the upper end face of the peripheral wall of the exhaust port and closes the opening, thereby blocking the air gap from communicating with the outside.

[0009] Furthermore, an inner ring is provided inside the exhaust port, and the upper end face of the inner ring is connected to the upper end face of the exhaust port, so that the upper opening diameter D1 of the exhaust port is smaller than the lower opening diameter D2, and the air gap is provided between the inner ring and the seal.

[0010] Furthermore, the sealing element is provided with a second abutting part that movably abuts against the lower end face of the inner ring, and the diameter of the second abutting part is D3, where D2 > D3 > D1.

[0011] Furthermore, the inner ring is provided with a plurality of connection ports, which are respectively connected to the air gap and the interior of the pot body.

[0012] Furthermore, the upper surface of the pot lid is provided with a groove, and the vent is located in the groove.

[0013] Furthermore, the sealing element is a silicone valve.

[0014] Furthermore, the pot lid is provided with several buckles, which are rotatably connected to the pot lid.

[0015] Furthermore, the upper surface of the pot body is provided with an arc edge extending outward in all directions, and the arc edge forms a groove with the outer wall of the pot body, the groove being adapted to the buckle.

[0016] Furthermore, an annular sealing ring is provided at the connection between the lid and the pot body.

[0017] Furthermore, a bracket is connected to the bottom of the pot body, and two pot ears are formed by extending outward from both ends of the bracket along its length.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The pot lid is equipped with an exhaust vent, and a sealing element is installed inside the exhaust vent. A vacuum pump is connected to the exhaust vent, which allows air inside the pot to be expelled through the sealing element, creating a vacuum-sealed space inside the pot, thereby extending the food's shelf life. Furthermore, the vacuum pump is separate from the pot lid, so if the vacuum pump is damaged, it does not affect the use of the pot lid and the pot body, greatly improving the convenience of food preservation. This invention features a simple structure, convenient operation, and strong practicality. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1-6 As shown, this utility model provides a vacuum-sealed cookware, including a detachably connected lid 1 and a pot body 2. The lid 1 is provided with an exhaust port 11, and the exhaust port 11 is equipped with a vertically movable sealing element 3. An air gap 4 communicating with the interior of the pot body 2 is provided between the sealing element 3 and the peripheral wall of the exhaust port 11. The sealing element 3 is provided with a first abutting part 31, which movably and sealingly abuts against the upper end face of the peripheral wall of the exhaust port 11, thereby isolating the air inside the pot body 2 from the outside. In this embodiment, the sealing element 3 is a silicone valve, which is hollow inside, saving raw materials and reducing production costs.

[0031] Specifically, the upper surface of the pot lid 1 is provided with a groove 12, and the exhaust port 11 is located in the groove 12. Therefore, when a vacuum pump is connected to the sealing member 3 for evacuation, the vacuum pump can quickly and accurately connect to the sealing member 3 under the action of the groove 12 and wrap the sealing member 3 inside. At the same time, it also restricts the movement of the vacuum pump to improve the stability of evacuation. When evacuating, the upper end of the sealing member 3 is in a negative pressure state and moves upward as a whole, so that the first abutting part 31 separates from the upper surface of the peripheral wall of the exhaust port 11 and forms an opening 5 that communicates with the air gap 4. The air in the pot body 2 is discharged to the outside through the air gap 4 and the opening 5 in sequence. The opening 5 has an annular structure.

[0032] After the vacuum pump is completed, it is disconnected from the sealing element 3. The lower end of the sealing element 3 is under negative pressure and moves downward as a whole, so that the first abutting part 31 seals against the upper end face of the peripheral wall of the exhaust port 11 and closes the opening 5, thereby blocking the air gap 4 from communicating with the outside world, so that the inside of the pot body 2 forms a vacuum seal, achieving the effect of preserving food.

[0033] Furthermore, such as Figure 3 , Figure 7 As shown, the exhaust port 11 is provided with an inner ring 6. The upper end face of the inner ring 6 is connected to the upper end face of the exhaust port 11, so that the upper opening diameter D1 of the exhaust port 11 is smaller than the lower opening diameter D2. The air gap 4 is provided between the inner ring 6 and the sealing member 3. The sealing member 3 is provided with a second abutting part 32 that movably abuts against the lower end face of the inner ring 6. The diameter of the second abutting part 32 is D3, and D2 > D3 > D1. In the natural state, the second abutting part 32 is separated from the lower end face of the inner ring 6. When the sealing member 3 moves upward as a whole under the action of the vacuum pump, the second abutting part 32 abuts against the inner ring 6 to limit the distance of movement of the sealing member 3, so that the sealing member 3 is stably installed in the exhaust port 11 in an "I" shape. The first abutting part 31 and the second abutting part 32 are both annular structures, which facilitates their adaptation to the annular opening 5 and the inner ring 6, respectively.

[0034] Furthermore, to ensure communication between the air gap 4 and the interior of the pot body 2, the inner ring 6 is provided with several connection ports 61, which are respectively connected to the air gap 4 and the interior of the pot body 2. Since D2 > D3 > D1, a gap is provided between the second abutment part 32 and the inner wall at the lower end of the exhaust port 11 to allow air to flow. When the second abutment part 32 abuts against the inner ring 6, the air in the pot body 2 will flow from the connection port 61 into the air gap 4 through the gap and be discharged from the opening 5 to achieve a vacuum seal inside the pot body 2, thereby preserving the food.

[0035] Preferably, such as Figure 8 As shown, the pot lid 1 is provided with a plurality of buckles 13, which are rotatably connected to the pot lid 1. The upper surface of the pot body 2 is provided with an arc edge 21 extending outward in all directions. The arc edge 21 and the outer wall of the pot body 2 form a groove 22. The groove 22 is adapted to the buckles 13 so as to fix the pot lid 1 and the pot body 2 by the buckles 13.

[0036] Furthermore, when the pot body 2 is in a vacuum state, in order to improve the sealing effect between the pot lid 1 and the pot body 2, an annular sealing ring 14 is also provided at the connection between the pot lid 1 and the pot body 2 to ensure that the air in the outer periphery will not enter from the gap at the connection.

[0037] Preferably, the bottom of the pot body 2 is connected to a bracket 23, and the two ends of the bracket 23 extend outward along its length to form two pot handles 231. When hot food is placed in the pot body 2, the user can lift and move it at any time by holding the two pot handles 231, which is more convenient and safer to use. Moreover, when placed on the table, there is a certain gap between the pot body 2 and the table under the action of the bracket 23, so there is no need to worry about the temperature of the pot body 2 being transferred to the table and causing the table to be burned by high temperature, making the user more at ease.

[0038] The working principle of this utility model is explained in detail below:

[0039] When in use, place the vacuum pump on the pot lid 1 with the connection end facing the groove 12 of the pot lid 1, and completely cover the sealing member 3. Then start the vacuum pump. At this time, the upper end of the sealing member 3 is under negative pressure and moves upward as a whole, so that the first abutting part 31 separates from the upper end surface of the peripheral wall of the exhaust port 11 and forms an opening 5 that communicates with the air gap 4. The air in the pot body 2 is discharged to the outside through the air gap 4 and the opening 5 in sequence.

[0040] After the air extraction is completed, the vacuum pump is disconnected from the sealing element 3. The lower end of the sealing element 3 is under negative pressure and moves downward as a whole, so that the first abutting part 31 seals against the upper end face of the peripheral wall of the exhaust port 11 and closes the opening 5, thereby blocking the communication between the air gap 4 and the outside world, and achieving the effect of preserving food.

[0041] The innovation of this utility model lies in the fact that the pot lid is equipped with an exhaust port, and the exhaust port is equipped with a sealing element. By connecting a vacuum pump to the exhaust port, the air inside the pot can be discharged through the sealing element, so that a vacuum sealing space is formed inside the pot, thereby extending the food preservation time. Moreover, the vacuum pump is separate from the pot lid, so when the vacuum pump is damaged, it does not affect the use of the pot lid and the pot body, which greatly improves the convenience of food preservation. This utility model has the characteristics of simple structure, convenient operation and strong practicality.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
