Description

Technical Field

[0001] The invention relates to the technical field of tire repair, in particular to a soft cavity device with the function of automatically repairing tires. Background Art

[0002] With the development of economy and the increase of people's income, more and more families start to buy cars. When a car is driving, sharp objects may puncture the tire when it encounters a road with bad road conditions. Especially when a nail punctures the tire, it will leak air, which will affect the safe driving of the car. Especially when driving at high speed, the tire suddenly punctures and leaks air, which is easy to cause safety accidents. If the tire needs to be repaired, the conventional tire repair operation needs to be repaired in a professional auto repair shop, which is time-consuming and easily affects the user's journey.

[0003] In order to solve the above problems, we propose a soft cavity device with automatic tire repair function to solve the above problems. Summary of the invention

[0004] In order to solve the problems in the background technology, the present invention provides a soft cavity device with the function of automatically repairing tires.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A soft cavity device with automatic tire repair function includes an annular cavity and internal liquid glue, wherein the liquid glue contains a soft sheet-like film, the outside of the annular cavity is arranged as a sticky glue coating area, the inner cavity of the annular cavity forms a sealed space, the liquid glue is filled in the sealed space, and the annular cavity is made of a soft film.

[0006] Preferably, the mixing ratio of the liquid glue and the soft sheet film is 3:1, and the soft sheet film will flow along with the flow of the liquid glue and play a role in filling and blocking the gaps to prevent the liquid glue from quickly flowing out of the device.

[0007] Preferably, the outer surface of the viscous rubber coating area is covered with a protective film, and the protective film plays a role in protecting the viscosity of the viscous rubber coating area; when in use, the protective film is removed and the annular cavity is tightly bonded to the inner wall of the tire.

[0008] Preferably, the liquid glue solidifies rapidly when encountering air.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the annular cavity device for automatically repairing tires is placed in the inner cavity of the tire, and the sticky glue coating area is tightly bonded to the outer side of the inner wall of the tire. When a nail pierces the tire, it will penetrate into the annular cavity. Due to the effect of the high-pressure air pressure inside the tire, the liquid glue in the annular cavity will drive the soft sheet-like film to flow to the gap created by the nail piercing the tire. At this time, the soft sheet-like film will block the gap, and the liquid glue that flows out will quickly solidify when it encounters air, thereby realizing automatic repair of the tire, providing protection for safe driving, increasing the safety of the car during driving, and reducing the occurrence of accidents. In addition, there is no need to send the tire to a professional repair shop for repair, reducing economic losses and not affecting the user's itinerary. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The embodiment of the present application provides a soft cavity device with an automatic tire repair function, and its main technology is: by tightly bonding the device of the present invention to the inner wall of the tire 7, when the nail pierces the tire 7, it will pierce into the annular cavity 1. Due to the pressure of the high-pressure air inside the tire 7, the liquid glue 2 in the annular cavity 1 will drive the soft sheet film 3 to flow to the gap created by the nail piercing the tire 7. At this time, the soft sheet film 3 will block the gap, and the liquid glue 2 that flows out will quickly solidify when it encounters air, thereby achieving rapid repair of the gap in the tire 7, so that the present invention has an automatic repair function, provides protection for safe driving, increases safety during vehicle driving, and reduces accidents.

[0013] Example: Refer to Figure 1 - Figure 4 As shown, a soft cavity device with an automatic tire repair function of this embodiment includes an annular cavity 1 and an internal liquid glue 2, the liquid glue 2 contains a soft sheet film 3, the outside of the annular cavity 1 is set as a sticky glue coating area 4, the inner cavity of the annular cavity 1 forms a sealed space 5, the liquid glue 2 is filled in the sealed space 5, and the annular cavity 1 is made of a soft film.

[0014] The mixing ratio of the liquid glue 2 and the soft sheet film 3 is 3:1. The soft sheet film 3 will flow along with the liquid glue 2 and fill and block the gaps to prevent the liquid glue 2 from quickly flowing out of the device.

[0015] In addition, a protective film 6 is covered on the outer surface of the viscous rubber coating area 4, and the protective film 6 plays a role in protecting the viscosity of the viscous rubber coating area 4; when in use, only the protective film 6 needs to be removed, and the annular cavity 1 can be tightly bonded to the inner wall of the tire 7 for use.

[0016] In some examples, the liquid glue 2 solidifies quickly when it encounters air.

[0017] The working principle of the present invention is: During use, by removing the protective film 6, the annular cavity 1 can be tightly bonded to the inner wall of the tire 7 for use. When a nail pierces the tire 7, the nail will penetrate into the annular cavity 1 with the pressure. At this time, under the pressure of the high-pressure air inside the tire 7, the liquid glue 2 in the annular cavity 1 will drive the soft sheet film 3 to flow to the gap created by the nail piercing the tire 7. Among them, the soft sheet film 3 will be stuck in the gap, playing a blocking role, which can prevent more liquid glue 2 from leaking out, and the leaked liquid glue 2 will solidify when it comes into contact with the external air; thereby, the gap between the nail and the tire 7 is blocked and repaired, thereby effectively preventing the internal high-pressure gas from leaking; through the above steps, when the nail is pulled out, the gap can also be automatically repaired to prevent leakage, without sending it to a professional repair shop for repair, reducing economic losses, and at the same time will not affect the user's itinerary.

[0018] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
