Description

Technical Field

[0001] The utility model belongs to the technical field of cups and pots, and particularly relates to a cup and pot airbag threadless vertical opening structure. Background Art

[0002] At present, a heat-insulating cup is generally a water-containing container made of ceramic or stainless steel materials plus a vacuum layer, with a lid on the top, tightly sealed, and the vacuum heat-insulating layer can delay the heat dissipation of liquids such as water contained inside to achieve the purpose of heat preservation. When most heat-insulating cups are capped, generally a threaded structure is arranged at the opening of the heat-insulating outer shell, and then the lid body is screwed tightly with the heat-insulating outer shell to cover and insulate the two.

[0003] For example, a heat-insulating pot with a pressure-limiting valve with the application number CN117918691A. The present invention includes a pot lid and a pot body. The pot lid is arranged above the pot body. A pressure-limiting valve communicating with the inside of the pot body is arranged at the upper part of the pot body. A pressure-relief switch device capable of opening or closing the pressure-limiting valve is connected to the pressure-limiting valve. The pressure-relief switch device includes a housing with an opening on one side, a pressure-relief switch rotating shaft, a pressure-relief lever rotating shaft, a pressure-relief switch and a pressure-relief lever; the housing is arranged on the pot body. One end of the piston of the pressure-limiting valve extends into the housing. The pressure-relief switch is arranged on the side of the opening of the housing, with the upper end connected to the inner top of the housing through the pressure-relief switch rotating shaft, the lower end connected to the bottom end of the pressure-relief lever, the pressure-relief lever connected to the middle part of the housing through the pressure-relief lever rotating shaft, and the top end connected to the piston. The present invention has the advantages of pressure-relief switch control for the steam generated inside, self-heating function, and convenient use.

[0004] The above heat-insulating pot realizes heat insulation by screwing the outer shell thread and the cup lid tightly. However, in this way, when the user caps the heat-insulating cup, the lid body needs to be rotated multiple times. During the rotation, the hot air inside the heat-insulating cup is likely to escape, resulting in a poor heat-insulating effect of the heat-insulating cup, and the process of opening and closing the heat-insulating cup also requires multiple turns of screwing, which is rather cumbersome. Therefore, it is necessary to improve and design a new opening and closing method for cups and pots. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cup and pot airbag threadless vertical opening structure, aiming to solve the technical problems that the switch method of screwing the outer shell thread tightly or the two-handed switch cover method in the above-mentioned prior art is rather troublesome and the hot air is likely to escape during the switch.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0036] In one embodiment of the present utility model, according to Figures 1-6 As shown, a cup kettle airbag threadless vertical open lid structure includes a cup body 100 and a lid body 200; a sealing device 300 is provided on the lid body 200. Through the sealing device 300, the lid body 200 can be sealingly arranged on the cup body 100. The sealing device 300 includes a base 310 and a deformable elastic airbag 320 sleeved on the base 310 and having a groove on the base. A pulling shaft 210 is provided on the base 310 that is completely and tightly wrapped. A lock switch 220 is provided on the lid body 200. The lock switch 220 is connected to the pulling shaft 210 through a rotating member 230. A guiding surface 240 is provided inside the lid body 200. The rotating member 230 abuts and rotates with the guiding surface 240. An opening 241 is provided in the middle of the guiding surface 240. One end of the pulling shaft 210 passes through the opening 241 and is connected to the rotating member 230. The other end of the pulling shaft 210 is connected to the base 310. When the lock switch 220 rotates, it drives the rotating member 230 to rotate. The rotating member 230 causes the pulling shaft 210 and the base 310 to move axially upward or downward; a limiting block 400 is also provided on the lid body 200, and the limiting block 400 can limit the flipping of the lock switch 220.

[0037] When the base 310 connected to the pulling shaft 210 moves upward, the elastic airbag 320 generates a radial expansion and bends outward to be clamped with the clamping interface 110 on the inner wall of the cup body 100, realizing the sealing of the lid body 200 and the cup body 100; when the base 310 connected to the pulling shaft 210 moves downward, the elastic airbag 320 resets and contracts to disengage from the inner wall of the cup body 100, realizing the opening of the lid body 200 and the cup body 100.

[0038] Specifically, when closing the lid, the latch switch 220 flips downward, driving the rotating member 230 to rotate on the guiding surface 240. The rotating member 230 causes the pulling shaft 210 and the base 310 to move axially upward, and the elastic airbag 320 is squeezed, generating a radial expansion and bending outward to be clamped with the clamping interface 110 on the inner wall of the cup body 100, realizing the lid closing (single - hand operation) of the lid body 200 and the cup body 100. When opening the lid, the latch switch 220 flips upward, driving the rotating member 230 to rotate on the guiding surface 240. The rotating member 230 causes the pulling shaft 210 and the base 310 to move axially downward, and the elastic airbag 320 resets and contracts to disengage from the inner wall of the cup body 100, realizing the lid opening (single - hand operation) of the lid body 200 and the cup body 100. A limiting block 400 is also provided on the lid body 200, and the limiting block 400 can move back and forth to limit the flipping of the latch switch 220.

[0039] Furthermore, the present utility model controls the opening and closing of the cup kettle by setting the latch switch 220, which is simple and convenient. At the same time, a sealing device 300 is provided, and closing can be achieved by clamping with the clamping interface 110 on the inner wall of the cup body 100, and the heat will not be dissipated due to the traditional screw - type lid closing. By setting the limiting block 400, the latch switch 220 can be simply and quickly locked, preventing accidental touch to open the latch switch 220 and causing the water in the cup kettle to flow out.

[0040] In another embodiment of the present utility model, according to Figure 4 as shown, the latch switch 220 is provided with a sliding protrusion 221, the bottom of the limiting block 400 is provided with a sliding groove 410, and a limiting auxiliary position 250 is provided on the lid body 200. The sliding protrusion 221 and the sliding groove 410 cooperate with each other, and the limiting block 400 can slide between the latch switch 220 and the limiting auxiliary position 250. When the limiting block 400 is completely located on the latch switch 220, the latch switch 220 can be flipped. When one end of the limiting block 400 is located on the latch switch 220 and the other end is located on the limiting auxiliary position 250, the flipping of the latch switch 220 is restricted.

[0041] Specifically, as Figures 2-4 shown, the lid body 200 has a cavity inside. The guiding surface 240 divides it into two parts. The rotating member 230 is located in the upper cavity, and the sealing device 300 is located in the lower cavity. The pulling shaft 210 penetrates the upper and lower cavities. When the limiting block 400 is completely located on the latch switch 220, the latch switch 220 can rotate together with the limiting block 400. When one end of the limiting block 400 is located on the latch switch 220 and the other end is located on the limiting auxiliary position 250, a block is formed at the end of the limiting auxiliary position 250, which will limit the flipping of the limiting block 400, and thus limit the flipping of the latch switch 220. At this time, the sliding protrusion 221 and the sliding groove 410 should be in an interference fit. In the case of no other limiting parts, when the sliding feeling is relatively tight, the above - mentioned function can be achieved. When the sliding feeling is relatively loose, the following limiting parts need to be cooperated.

[0042] As Figures 2-4 , an elastic first protrusion 222 is provided on the latch switch 220, and an elastic second protrusion 420 and a third protrusion 430 are provided at the bottom of the limiting block 400. During the movement of the limiting block 400, the first protrusion 222, the second protrusion 420, and the third protrusion 430 can relatively deform and change the position sequence. From Figure 2 and 3 , it can be seen that both the second protrusion 420 and the third protrusion 430 are located on the left side of the first protrusion 222. At this time, it is in the locked limit state, and the first protrusion 222 will exert a limiting effect on the third protrusion 430 to keep the limiting block 400 in a state. When the user pushes the limiting block 400 forcefully to the right, at this time, the second protrusion 420 and the third protrusion 430 are located on the right side of the first protrusion 222, and the position sequence changes. At this time, it is in the unlocked state, and the latch switch 220 can be flipped. At this time, the first protrusion 222 exerts a limiting effect on the second protrusion 420 to keep the limiting block 400 in a state.

[0043] A first blocking block 223 is provided on the pin buckle switch 220, and a second blocking block 440 is provided at the bottom of the limiting block 400. The first blocking block 223 and the second blocking block 440 cooperate with each other to prevent the limiting block 400 from slipping relative to the latch switch 220 or being touched and opened, playing a role of secondary insurance.

[0044] Ribs 251 are provided on the limiting auxiliary position 250. Specifically, the ribs 251 are used to ensure that the limiting block 400 is not detached and moves smoothly, and at the same time increase the damping feeling when pushing.

[0045] In another embodiment of the present invention, according to Figure 3 and 6 shown, the middle part of the rotating member 230 has an avoidance space 231, and one end of the pulling shaft 210 is inserted into the avoidance space 231 and connected to the rotating member 230. A through first insertion hole 232 is provided on the rotating member 230, and a through second insertion hole 211 is provided at one end of the pulling shaft 210. When one end of the pulling shaft 210 is inserted into the avoidance space 231, the first insertion hole 232 and the second insertion hole 211 are aligned with each other, and an insertion pin penetrates into the first insertion hole 232 and the second insertion hole 211 to connect the pulling shaft 210 and the rotating member 230. Specifically, the middle part of the rotating member 230 has an avoidance space 231, and one end of the pulling shaft 210 is inserted into the avoidance space 231 and connected to the rotating member 230. This connection method is relatively stable and saves space at the same time.

[0046] In another embodiment of the present invention, according to Figures 1-5As shown, the rotating member 230 is an elastic member, and the bottom side and one side of the rotating member 230 are smooth arcs. Specifically, the bottom and the sliding side being smooth arcs are beneficial for sliding with the guiding surface 240, making the rotation of the rotating member 230 smoother, and making the opening and closing of the cover body 200 smoother.

[0047] In another embodiment of the present utility model, as Figures 1-5 shown, a spring 260 is sleeved on the pulling shaft 210. One end of the spring 260 abuts against the base 310, and the other end abuts against the guiding surface 240. Specifically, the spring 260 is a design for auxiliary reset. When the pulling shaft 210 and the base 310 are axially upward, the spring 260 is compressed, generating a force to restore. When the latch switch 220 is covered, force is required, with a damping feeling. When opening the lid, it will accelerate the downward movement of the pulling shaft 210, accelerating the reset contraction of the elastic airbag 320 and separating it from the inner wall of the cup body 100. At the same time, there is a clamping connection between the latch switch 220 and the edge of the cover body 200. It can be that there is a clamping protrusion on the latch switch 220, and there is a clamping groove on the edge of the cover body 200, or there is a clamping groove on the latch switch 220,

[0048] and there is a clamping protrusion on the 220. This is a mature prior art, and this patent will not elaborate further.

[0049] In another embodiment of the present utility model, as Figure 1 shown, a filter net 270 is further provided at the bottom of the cover body 200. Specifically, the filter net 270 is used to filter tea leaves, supplements and other tea products soaked in water, realizing solid-liquid separation.

[0050] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, its structural form can be flexible and changeable, and a series of products can be derived. Just making several simple deductions or replacements should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
