An air plug structure is designed, including an observation channel and a deformation member. The deformation member protrudes upward or depression downward when the air pressure changes. The air flow state inside the valve is determined by the deformation state, providing a prompt function.
It realizes the determination of the internal airflow state of the air valve based on the deformation state of the deformation part, provides an intuitive state prompt function, and solves the problem that the state cannot be judged intuitively in the prior art.

Abstract
Description
Technical Field
[0001] The utility model relates to an air plug structure and a vacuum air valve structure. Background Art
[0002] Prior art, such as Chinese utility model patent document with publication number CN219447825U, discloses a vacuum bag which can be automatically sealed after evacuation, comprising a vacuum bag and a bag mouth arranged on the vacuum bag, a sealing air valve which can be sealed on the bag mouth, and a first sealing cover which can be covered on the bag mouth, an exhaust port which is connected to the bag mouth is provided on the upper surface of the first sealing cover, a sealing plug is provided at the exhaust port, an exhaust channel is left between the sealing plug and the inner side wall of the exhaust port, an elastic sealing structure which can block the exhaust channel is provided on the sealing plug, and when the air pressure in the vacuum bag is greater than the air pressure on one side of the upper surface of the first sealing cover, the elastic sealing structure will be pushed open to make the exhaust channel conductive.
[0003] Based on the above, in the prior art, the switching between the closed state and the conductive state is achieved by moving the sealing plug up and down. Although it can achieve sealing and air sealing or conductive exhaust, it does not have a prompt function, that is, when the sealing plug is in the closed state or the conductive state, it cannot serve as a status prompt, resulting in the user being unable to intuitively judge whether it has entered the closed state or the conductive state, and further improvement is needed. Utility Model Content
[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an air plug structure and a vacuum air valve structure.
[0005] An air plug structure designed for this purpose, the air plug, an observation channel is arranged inside the air plug, one end of the observation channel is connected to the interior of the air valve, and the other end of the observation channel is provided with a deformable part for closing the observation channel, and the deformable part will produce an upward convex or downward concave deformation when the air pressure inside the air valve changes.
[0006] Compared with the existing technology, the utility model has the following advantages: when the gas plug is in the exhaust state, the gas inside the gas valve communicates with the external gas, and the deformable member is affected by the airflow and deforms to bulge upward. When the gas plug is in the closed and airtight state, the inside of the gas valve is in a vacuum negative pressure state, and the deformable member is affected by the negative pressure and deforms to sag downward. Therefore, the airflow state inside the gas valve can be judged according to the deformation state of the deformable member, which has a prompting function. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] See also Figure 1-Figure 5 , an air plug structure, the air plug 20, the air plug 20 is provided with an observation channel 210, one end of the observation channel 210 is connected to the inside of the air valve 10, and the other end of the observation channel 210 is provided with a deformable member 30 for closing the observation channel 210, and the deformable member 30 is deformed to bulge upward or sink downward when the air pressure inside the air valve 10 changes. Compared with the existing technology, when the air plug is in the exhaust state, the gas inside the air valve is interconnected with the external gas, and at this time, the deformable member is affected by the airflow and deforms to bulge upward. When the air plug is in the closed and sealed state, the inside of the air valve is in a vacuum negative pressure state, and at this time, the deformable member is affected by the negative pressure to deform and sink downward. Thereby, it is possible to judge the airflow state inside the air valve according to the deformation state of the deformable member, and it has a prompt function.
[0014] See also Figure 3 The observation channel 210 is composed of an air intake section 211 and an observation section 212 which are connected to each other. The air intake section 211 is connected to the inside of the air valve 10. The observation section 212 is arranged on the upper part of the air plug 20. The deformation member 30 is arranged in the observation section 212. In actual use, the airflow inside the air valve 10 is connected to the airflow inside the air intake section 211. When the airflow of the air valve 10 changes, it affects the airflow inside the air intake section 211, thereby affecting the deformation member 30 and causing it to deform. The setting of the observation section 212 can facilitate the user to quickly observe the specific shape of the deformation member 30, thereby determining the airflow state inside the air valve 10.
[0015] See also Figure 3 The observation section 212 is in the shape of a tapered hole that is larger at the top and smaller at the bottom. The tapered setting allows the user to quickly observe the state of the deformable member 30 from top to bottom.
[0016] See also Figures 1 to 5A vacuum air valve structure, wherein an inner cavity 130 and an outer cavity 120 are arranged in the air valve 10, an air hole 110 is arranged between the inner cavity 130 and the outer cavity 120, an air plug 20 is arranged in the air hole 110, an observation channel 210 of the air plug 20 is communicated with the inner cavity 130, a limiting member 220 and an air sealing member 230 are arranged on the air plug 20, an exhaust hole 221 is arranged on the limiting member 220, and the limiting member 220 can be fitted with the inner top surface of the inner cavity 130 when the air plug 20 moves upward, at this time, the air flow inside the air valve 10 can be discharged outward through the exhaust hole 221 upward through the air hole 110 and the air plug 20, as shown in FIG. Figure 1 As shown, in this state, the deformable member is affected by the airflow and deforms to bulge upward. When negative pressure is generated, the air sealing member 230 fits with the inner bottom surface of the outer cavity 120, as shown in FIG. Figure 2 As shown, in this state, the airflow in the inner cavity and the airflow in the outer cavity cannot communicate with each other, and the negative pressure causes the deformable member to deform and sink downward.
