[0022] In view of the technical problems described in the background art, as shown in the figure, a tire repair device is provided, comprising: a bottle body 1, wherein the bottle body 1 has a receiving space and stores tire repair fluid, and the bottle body 1 has a bottle opening at the top; a bottle cap 2, wherein the bottle cap 2 is threadedly connected to the bottle opening of the bottle body 1, the bottle cap 2 has an air inlet 3 for compressed gas to enter, and the upper inner wall of the bottle cap 2 has a vent groove 4 at a circumferential position, the vent groove 4 communicating with the air inlet 3, and the upper inner wall of the bottle cap 2 has a connecting pipe opening 5 at the center; a first sealing gasket 6, wherein the first sealing gasket 6 has a hole 7 at its center, the center hole 7 having circumferentially distributed slits 8; the first sealing gasket 6 passes through the hole 7 and the connecting pipe opening 5, and is installed on the upper inner wall of the bottle cap 2; and a pipe 9, wherein the first end of the pipe 9... The second end of the pipe 9 extends into the bottle body 1 in conjunction with the connecting port 5; a one-way component 10 includes an upper support 11, a lower support 12, and a second sealing gasket 13. The upper support 11 is connected to the second end of the pipe 9, the lower support 12 is connected to the upper support 11, and the second sealing gasket 13 is disposed inside the upper support 11 and the lower support 12. The center of the second sealing gasket 13 has circumferentially distributed slits 8; a glue dispensing tube 14 is connected to the bottle cap 2 and is connected to the connecting port 5; wherein, external compressed gas enters through the air inlet 3, passes through the first sealing gasket 6, and enters the bottle body 1. The tire sealant in the bottle body 1 is discharged through the one-way component 10 and then through the glue dispensing tube 14.

[0023] This tire repair device mainly consists of a bottle body 1, a bottle cap 2, a first sealing gasket 6, a pipe 9, a one-way component 10, a glue dispensing tube 14, and a protective cap 15. These components work together to achieve functions such as tire sealant storage, compressed gas introduction, and tire sealant output, allowing tire repair operations to be completed without inverting the bottle body 1.

[0024] Bottle 1 is the main structure of the entire device, and its interior has a storage space for storing tire sealant. Bottle 1 has an opening at the top, which serves as a connection to the cap 2 and a channel for the tire sealant and gas to enter and exit.

[0025] The bottle cap 2 is threaded to the bottle opening of the bottle body 1, facilitating disassembly and installation and allowing for the addition of tire sealant to the bottle body 1. The bottle cap 2 has an air inlet 3 for compressed gas, the diameter of which can be designed to meet the required gas flow rate. The air inlet 3 is used to connect to an external compressed gas source, such as an air pump. A venting groove 4 is located on the circumference of the upper inner wall of the bottle cap 2. The venting groove 4 communicates with the air inlet 3 but not with the connecting pipe 5, guiding compressed gas into the bottle body 1. A connecting pipe 5 is located at the center of the upper inner wall of the bottle cap 2. The connecting pipe 5 connects to the pipe 9 and the dispensing hose 14, enabling gas conduction and tire sealant output. The inner diameter of the connecting pipe 5 is matched to the outer diameter of the pipe 9 and the dispensing hose 14 to ensure a tight connection.

[0026] The first sealing gasket 6 is installed on the inner wall of the bottle cap 2, with a central hole 7 and circumferentially distributed slits 8 at the hole 7. These slits 8 are closed when not under pressure, effectively preventing the tire sealant from leaking out of the bottle 1. When compressed gas enters from the air inlet 3, the gas pressure causes the slits 8 to open, allowing gas to enter the bottle 1 smoothly. The first sealing gasket 6 passes through the hole 7 and the connecting pipe 5, and is installed on the inner wall of the bottle cap 2. During installation, it is necessary to ensure that the sealing gasket and the bottle cap 2 fit tightly to prevent gas leakage.

[0027] The first end of pipe 9 mates with the connecting port 5, using either an interference fit or a threaded connection to ensure a secure and airtight connection. The second end of pipe 9 extends into the bottle body 1, its length designed according to the height of the bottle body 1 to ensure smooth extraction of the tire sealant from the bottom of the bottle body 1. The inner diameter of pipe 9 can be selected based on the required flow rate of the tire sealant. Pipe 9 can be made of plastic or metal, chosen based on the actual usage environment and cost factors.

[0028] One-way component 10 is supplied with tire sealant flowing out from the dispensing tube 14 after passing through it. One-way component 10 includes an upper bracket 11, a lower bracket 12, and a second sealing gasket 13. The upper bracket 11 is connected to the second end of the pipe 9, and the lower bracket 12 is connected to the upper bracket 11 to form a closed space for installing the second sealing gasket 13.

[0029] The second sealing gasket 13 is disposed inside the upper support 11 and the lower support 12, and its center also has circumferentially distributed slits 8. When the tire sealant in the bottle 1 flows upward under the action of compressed gas, the liquid pressure causes the slits 8 of the second sealing gasket 13 to open, allowing the tire sealant to pass smoothly; when the tire sealant stops flowing or there is reverse pressure, the slits 8 will automatically close to prevent the tire sealant from flowing back into the bottle 1, ensuring that the tire sealant can be continuously and stably output. The material of the second sealing gasket 13 can also be an elastic sealing material such as silicone rubber.

[0030] The dispensing tube 14 is connected to the connecting port 5 and is used to discharge the tire sealant through the one-way component 10 into the tire. The dispensing position of the dispensing tube 14 is provided with a threaded structure, which can be used to connect the tire valve or other corresponding connectors, facilitating the connection between the dispensing tube 14 and the tire. The length and inner diameter of the dispensing tube 14 can be designed according to actual usage requirements.

[0031] The specific working process is as follows: When tire repair is required, an external compressed gas source (such as an air pump or air compressor) is connected to the air inlet 3. The compressed gas enters the venting groove 4 of the bottle cap 2 through the air inlet 3, and then enters the bottle body 1 through the gap 8 of the first sealing gasket 6. As the gas pressure inside the bottle body 1 increases, the tire sealant flows upward under pressure and enters the one-way component 10 through the pipe 9. In the one-way component 10, the tire sealant overcomes the resistance of the gap 8 of the second sealing gasket 13, causing the gap 8 to open. The tire sealant then smoothly passes through the one-way component 10 and enters the dispensing tube 14, and finally is discharged into the tire through the dispensing tube 14, completing the tire repair operation. When the input of compressed gas stops, the gap 8 of the second sealing gasket 13 automatically closes to prevent the tire sealant from flowing back into the bottle body 1.

[0032] In the above solution, the user only needs to connect the device appropriately to the tire, and through a simple operation, allow external compressed gas to enter the bottle 1, which can quickly deliver the tire sealant into the tire for tire repair, greatly shortening the repair time. It is especially suitable for quickly repairing tires in emergency situations such as outdoors, providing great convenience for users' travel. No inverted use is required. Through the special design of the first sealing gasket 6 and the second sealing gasket 13 in the one-way component 10, the first sealing gasket 6 has a circumferentially arrayed array of slits 8 in its central hole 7, and the second sealing gasket 13 also has a circumferentially arrayed array of slits 8 in its center. This structure ensures that compressed gas and tire sealant can pass smoothly while effectively preventing gas and liquid leakage, simplifying the structure and reducing production costs.

[0033] Preferably, the present invention includes a protective cap 15, which is threadedly connected to the air inlet 3. The protective cap 15 is threadedly connected to the air inlet 3 to protect the air inlet 3 and prevent dust, debris, etc. from entering the air inlet 3, thus affecting the entry of compressed gas and the normal use of the device.

[0034] As an feasible technical solution, the upper support 11 has a first barb structure 16 on its outer circumferential wall, which is fitted and connected to the inner wall of the pipe 9. This connection method enhances the connection strength between the upper support 11 and the pipe 9, preventing the one-way component 10 from detaching during use. The shape of the first barb structure 16 can be triangular or trapezoidal.

[0035] As an feasible technical solution, a second barb structure 17 is provided at the connection position between the bottle cap 2 and the dispensing tube 14. The second barb structure 17 is fitted into the inner wall of the dispensing tube 14. The dispensing tube 14 is connected to the bottle cap 2, and the second barb structure 17 at the connection position, fitted into the inner wall of the dispensing tube 14, ensures a secure connection between the dispensing tube 14 and the bottle cap 2, preventing the dispensing tube 14 from falling off during use. The design of the second barb structure 17 is similar to that of the first barb structure 16.

[0036] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
