[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide an easy-tear cover that is vented and moisture-proof. The easy-tear cover is intended to solve the technical problem that the easy-tear cover in the existing technology is usually unable to regain its original sealing state after opening. This means that once the package is opened, external air, moisture and other possible contaminants may enter the interior of the package, thereby affecting the freshness, safety and shelf life of food or medicine.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides an easy-tear cover with air exhaust and moisture-proof function, which includes an easy-tear cover body, a sealing film and a pull ring. The surface of the easy-tear cover body is connected to the sealing film, the surface of the sealing film is connected to the pull ring, and a sealing plate is provided on the bottom side of the easy-tear cover body. A rotating hole is opened on the surface of the sealing plate, and a rotating shaft passes through the interior of the rotating hole. The rotating shaft is connected to the bottom side of the easy-tear cover body, the upper surface of the sealing plate is connected to a first rubber ring, and the side surface of the sealing plate is connected to a handle.

[0009] When the easy-tear cover of the present technical solution is used, pulling the handle can generate a force on the sealing plate. The sealing plate can drive the rotating hole to rotate on the surface of the rotating shaft under the force. When the sealing plate rotates, it can drive the first rubber ring to rotate. When the sealing plate drives the first rubber ring to rotate to cover the opening of the easy-tear cover body, the easy-tear cover body can be sealed.

[0010] Preferably, the sealing plate forms a rotating structure between the rotating hole and the rotating shaft. The handle is pulled to generate a force on the sealing plate, and the sealing plate is driven by the force to drive the rotating hole to rotate on the surface of the rotating shaft.

[0011] Furthermore, the first rubber ring forms a sealing structure between the easy-tear cover body and the sealing plate. When the sealing plate drives the first rubber ring to rotate to cover the opening of the easy-tear cover body, the easy-tear cover body can be sealed.

[0012] Furthermore, the surface of the sealing plate is connected to the exhaust pipe, a tube core is inserted into the interior of the exhaust pipe, a through hole is opened on the surface of the tube core, a second rubber ring is connected to the surface of the tube core, a spring bar is connected between the tube core and the exhaust pipe, and a fourth rubber ring is connected to the upper surface of the tube core.

[0013] Furthermore, the cylinder core and the exhaust pipe are in sliding connection, and the cylinder core can move downward inside the exhaust pipe when squeezed. When the cylinder core drives the second rubber ring to move downward to the bottom position of the exhaust pipe, air can be extracted.

[0014] Furthermore, the second rubber ring forms a sealing structure between the cylinder core and the exhaust cylinder, and the second rubber ring can prevent air from penetrating through the gap between the cylinder core and the exhaust cylinder.

[0015] Furthermore, the tube core and the spring strip form an elastic telescopic structure. The downward movement of the tube core can compress the spring strip. After the force disappears, the spring strip drives the tube core to reset through its own elastic force. After the tube core is reset, it can drive the fourth rubber ring into the interior of the exhaust pipe.

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In the utility model, pulling the handle can generate a force on the sealing plate. The sealing plate can drive the rotating hole to rotate on the surface of the rotating shaft under the force. When the sealing plate rotates, the first rubber ring can be driven to rotate. When the sealing plate drives the first rubber ring to rotate to cover the opening of the easy-tear cover body, the easy-tear cover body can be sealed, thereby preventing moisture from entering the interior of the cylinder connected to the easy-tear cover, achieving a moisture-proof effect.

[0019] The utility model is that a syringe is inserted into the through hole and squeezes the cylinder core downwards. The cylinder core is squeezed and can move downwards inside the exhaust cylinder and compress the spring strip. When the cylinder core drives the second rubber ring to move downwards to the bottom position of the exhaust cylinder, air is evacuated from the cylinder body connected to the easy-tear cover through the syringe. After the syringe is pulled out, the spring strip drives the fourth rubber ring into the interior of the exhaust cylinder through the cylinder core. The fourth rubber ring can seal the exhaust cylinder and the cylinder core. After exhaust, the development and growth of aerobic bacteria and molds can be effectively prevented. These microorganisms are easy to reproduce in an aerobic environment, thereby affecting the shelf life and safety of food. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] This embodiment is an easy-tear cover that is vented and moisture-proof. The structural diagram is shown in FIG. Figure 1-7As shown, the easy-tear cover includes an easy-tear cover body 1, a sealing film 2 and a pull ring 3. The surface of the easy-tear cover body 1 is connected to the sealing film 2, and the surface of the sealing film 2 is connected to the pull ring 3. A sealing plate 4 is provided on the bottom side of the easy-tear cover body 1, and a rotating hole 5 is opened on the surface of the sealing plate 4. A rotating shaft 6 passes through the interior of the rotating hole 5, and the rotating shaft 6 is connected to the bottom side of the easy-tear cover body 1. A first rubber ring 7 is connected to the upper surface of the sealing plate 4, and a handle 8 is connected to the side surface of the sealing plate 4.

[0029] The sealing plate 4 forms a rotating structure through the rotating hole 5 and the rotating shaft 6 , and the first rubber ring 7 forms a sealing structure between the easy-tear cover body 1 and the sealing plate 4 .

[0030] In addition, the surface of the sealing plate 4 is connected to the exhaust tube 9, and the interior of the exhaust tube 9 is inserted with a tube core 10. A through hole 11 is opened on the surface of the tube core 10, and a second rubber ring 12 is connected to the surface of the tube core 10. A spring bar 13 is connected between the tube core 10 and the exhaust tube 9. The upper surface of the tube core 10 is connected to a fourth rubber ring 14. The tube core 10 and the exhaust tube 9 are slidingly connected. The second rubber ring 12 constitutes a sealing structure between the tube core 10 and the exhaust tube 9, and the tube core 10 and the spring bar 13 constitute an elastic telescopic structure.

[0031] Working principle: When using the device of the present technical solution, the easy-tear cover is first used by pulling the pull ring 3. The sealing film 2 can be torn off from the surface of the easy-tear cover body 1 through the pull ring 3. After the sealing film 2 is torn off, the items can be taken out. After the items are taken out, the handle 8 can be pulled. The pull force of the handle 8 can generate a force on the sealing plate 4. The sealing plate 4 can drive the rotating hole 5 to rotate on the surface of the rotating shaft 6 when the force is applied. When the sealing plate 4 rotates, it can drive the first rubber ring 7 to rotate. When the sealing plate 4 drives the first rubber ring 7 to rotate to cover the opening of the easy-tear cover body 1, the easy-tear cover body 1 can be sealed, thereby achieving a moisture-proof effect.

[0032] When pumping air, insert the end of the syringe into the inside of the through hole 11, and then the core 10 can be squeezed downward by the syringe. At this time, the fourth rubber ring 14 is used to seal between the syringe and the core 10. At the same time, the core 10 is squeezed and can move downward inside the exhaust tube 9. The downward movement of the core 10 can compress the spring strip 13. When the core 10 drives the second rubber ring 12 to move downward to the bottom position of the exhaust tube 9, the inside of the cylinder connected to the easy-to-tear cover is pumped out by the syringe. After the pumping is completed, the syringe is pulled out. During this process, the spring strip 13 drives the core 10 to reset by its own elastic force. After the core 10 is reset, it can drive the fourth rubber ring 14 to enter the interior of the exhaust tube 9. The fourth rubber ring 14 can be used to seal between the exhaust tube 9 and the core 10.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
