Breathing lid capable of adaptively balancing air pressure

#The disclosure relates to the technical field of airbags capable of adapting to air pressure, and more specifically relates to a breathing lid capable of adaptively balancing air pressure.

#At present, a product inside a can is usually sealed with an aluminum film or tin foil. However, during actual use, especially in areas with great pressure difference and temperature difference such as aircraft transportation, or for microbial products that generate gas, such as protein powder, coffee beans, milk powder, etc., it is prone to deformation of the can or rupture of the sealing film. If the external pressure is too high, the side wall of the can will be squeezed, which will lead to concave deformation of the can. If the external pressure is too low, the inner wall of the can will swell, and the can may even burst directly, which will affect the sales of the product. The method of providing a through hole in the sealing film and arranging a thin film with a waterproof and dustproof screen in the through hole may solve the problem of air pressure, but there is gas exchange between the inside and the outside of the can, which easily leads to the deterioration of the product in the can. Therefore, there is an urgent need for an improved technology to solve this problem in the prior art.

#In order to overcome the above defect in the prior art, an embodiment of the disclosure provides a breathing lid capable of adaptively balancing air pressure so as to solve the problem proposed in the Background.

#A breathing lid capable of adaptively balancing air pressure, as shown in FIG. 1 to FIG. 5, includes a can lid 1 and an airbag body 2. The airbag body 2 is clamped in the can lid 1. The airbag body 2 includes a connecting outer ring 21, a soft connecting inner ring 22, a ventilation component 3, and a mounting seat 4. The connecting outer ring 21 is in an annular structure, and the soft connecting inner ring 22 is in a convex structure. The soft connecting inner ring 22 is arranged on an inner side of the connecting outer ring 21, and the mounting seat 4 is mounted on the inner side of the connecting outer ring 21. The mounting seat 4 is provided with the ventilation component 3. The ventilation component 3 includes a connecting column 31, a ventilation column 32, a silicone sleeve 33, an air-permeable film 34, and a limiting convex ring 35. The connecting column 31 is arranged on the mounting seat 4, and the ventilation column 32 is arranged in the connecting column 31. The silicone sleeve 33 is sleeved at a top end of the ventilation column 32, and the limiting convex ring 35 is arranged at a side end of the ventilation column 32. The air-permeable film 34 is arranged at a bottom end of the ventilation column 32.
