Description

Technical Field

[0001] The invention relates to the technical field of tire repair equipment, and in particular to a vehicle tire repair system. Background Art

[0002] With the development of economy and the increase of people's income, more and more families own private cars, which leads to an increasing number of cars on the road and an increasing number of car failures. For example, when a car is driving, it is inevitable that the tire will be punctured. Especially when such an accident occurs on the highway, how to quickly repair the tire is particularly important.

[0003] Existing automobile tire repair usually adopts the method of installing a tire sealant bottle on an air pump, and outputting the tire sealant into the tire through the air pump. For example, a Chinese utility model patent with publication number CN221462481U discloses an air pump, a tire sealant bottle, and an integrated inflation and tire repair device. The integrated inflation and tire repair device includes an air pump and a tire sealant bottle. The air pump includes a housing and an air source generator, a valved air nozzle and a three-way valve arranged in the housing. The tire sealant bottle includes a bottle body, a liquid outlet device and a liquid outlet pipeline. The tire sealant bottle in the embodiment of the utility model is installed on the air pump by mutually snapping the liquid outlet device with the mounting part of the air pump housing. The three-way valve in the air pump housing is connected to the first air inlet of the liquid outlet device of the tire sealant bottle. The gas generated by the air source generator in the air pump enters the tire sealant bottle through the three-way valve and the first air inlet of the liquid outlet device. The tire sealant in the tire sealant bottle flows out from the liquid outlet and reaches the tire through the liquid outlet pipeline. The tire sealant bottle can be directly inserted into the air pump for inflation and tire repair, which simplifies and facilitates the connection between the tire sealant bottle and the air pump.

[0004] The above solution has the following problems: ① If the air pump stops suddenly, the pressure in the tire sealant bottle will push the sealant back into the air pump, damaging it.

[0005] ② If the user is negligent or uses it improperly and starts the air pump before the liquid outlet is connected to the tire, the tire sealant will be accidentally discharged and splash onto the tread. The lumps formed after the tire sealant solidifies may cause vehicle instability when driving at high speeds, and even require the tire to be disassembled for cleaning, which is extremely troublesome.

[0006] ③. The tire sealant bottle cannot be placed directly on a flat surface. It is usually inverted and mounted on the air pump through the bottle cap for tire repair. In this way, the vibration generated by the air pump is directly transmitted to the bottle body, causing the tire sealant inside to continue to shake, affecting the delivery efficiency of the tire sealant. Summary of the invention

[0007] In order to solve the above problems, the purpose of the present invention is to provide a vehicle tire repair system, in which a first one-way valve is arranged in the air intake pipe or the air intake channel, so as to prevent the liquid inside the bottle from flowing back into the air pump when the air pump suddenly stops, thereby damaging the air pump. A second one-way valve is arranged at the end of the liquid outlet pipe, and when it is not connected to the tire air nozzle, the second one-way valve normally closes the liquid pipe; when it is connected to the tire air nozzle, the liquid pipe is opened under the action of the ejector pin of the tire air nozzle, and the tire repair liquid is guided into the tire, which is very convenient and safe. In addition, the bottle cap in the system can be inverted and erected on the ground through a support frame, so that the tire repair liquid bottle and the air pump can be used separately, reducing the influence of the vibration generated when the air pump is working on the infusion of the tire repair liquid bottle, thereby improving the efficiency of tire repair.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: A vehicle tire repair system includes an air pump and a tire repair liquid bottle, the tire repair liquid bottle includes a bottle cap and a bottle body, the bottle cap is provided with an air inlet nozzle connected to the air pump through an air inlet pipe, and a liquid outlet nozzle connected to the tire through a liquid outlet pipe, the air inlet nozzle is communicated with the inside of the bottle body through an air inlet channel, and the liquid outlet nozzle is communicated with the inside of the bottle body through a liquid outlet channel, and is characterized in that: The air inlet pipe or the air inlet passage is provided with a first one-way valve, which is suitable for the air inlet pipe to one-wayly inlet air into the bottle body; A second one-way valve is inserted at the end of the liquid outlet pipe, which is suitable for preventing liquid from flowing out of the liquid outlet pipe when the liquid outlet pipe is not connected to the tire.

[0009] In the above technical scheme, the tire repair system includes an air pump and a tire repair liquid bottle connected to each other. The liquid outlet pipe of the tire repair liquid bottle is connected to the tire. When the air pump is started, air is input into the bottle body through the air inlet pipe and the air inlet channel. The air presses the liquid into the liquid outlet channel and comes out from the liquid outlet nozzle into the liquid outlet pipe, and finally fills the tire. A first one-way valve is provided in the air inlet pipe or the air inlet channel, which is suitable for the one-way air intake of the air inlet pipe into the bottle body, so as to prevent the pressure in the tire repair liquid bottle from pressing the tire repair liquid back into the air pump when the air pump suddenly stops, thereby damaging the air pump. A second one-way valve is provided at the end of the liquid outlet pipe, which is suitable for preventing the liquid outlet pipe from discharging liquid when the liquid outlet pipe is not connected to the tire, thereby preventing the user from starting the air pump first when the liquid outlet is not connected to the tire due to negligence or improper use, which will cause the tire repair liquid to be accidentally discharged and splashed onto the tread, making it difficult to clean.

[0010] Preferably, the first one-way valve is arranged in the air inlet channel, and comprises a first valve core and a sealing ball. A flow channel is formed in the first valve core. The air inlet channel comprises a wide channel and a narrow channel arranged from outside to inside. A step is formed between the wide channel and the narrow channel. The step is provided with a plurality of support columns extending circumferentially into the wide channel. A medium groove communicating with the narrow channel and the wide channel is formed between adjacent support columns. The first valve core is arranged in the wide channel. The sealing ball is arranged in the accommodating cavity between the wide channel and the narrow channel, and the diameter of the sealing ball is larger than the inner diameter of the narrow channel. When the air inlet channel takes in air, the sealing ball is pushed open to make it abut against a plurality of support columns, and air enters the bottle body along the medium groove through the flow channel; when the air inlet channel discharges liquid, the sealing ball blocks the flow channel, and the flow channel is not connected to the medium groove.

[0011] In the above technical solution, the air inlet and outlet passages are configured to be wide outside and narrow inside, and a plurality of medium grooves are formed on the steps between the wide channel and the narrow channel. When air is taken in, the airflow enters the wide channel, pushes the sealing ball open through the flow channel in the first valve core, and enters the bottle cap through the medium groove, pressing the liquid in the bottle into the liquid outlet passage. When the air pump stops working unexpectedly, the liquid in the bottle enters the narrow channel under the action of pressure, pushes the sealing ball to the front end of the first valve core to seal the flow channel, thereby preventing the liquid in the bottle from flowing back into the air pump and damaging the air pump.

[0012] Preferably, the first valve core includes a main body that fits tightly with the inner wall of the wide channel and a convex portion formed on the main body and extending toward the narrow channel, a gap is formed between the convex portion and the inner wall of the wide channel; the side wall of the main body is provided with an external thread that fits tightly with the inner wall of the wide channel. In this technical solution, a gap is formed between the convex portion and the inner wall of the pipeline, making it easier to install the first valve core into the pipeline during installation, thereby improving installation efficiency. In addition, the external thread on the side wall of the main body can achieve a better sealing effect.

[0013] Preferably, the outer side of the main body is provided with a screwing opening adapted to a screwdriver bit. In this technical solution, the screwing opening on the main body of the valve core can facilitate users to use a screwdriver for screwing, which is more convenient.

[0014] Preferably, the second one-way valve comprises a connecting nozzle inserted into the outlet of the liquid outlet pipe and a connecting sleeve partially sleeved on the connecting nozzle, and a connecting channel is formed on the inner side of another part of the connecting sleeve; a liquid conducting channel communicating with the liquid outlet pipe and the connecting channel is formed in the connecting nozzle, and a second valve core is arranged in the liquid conducting channel, and the second valve core comprises an inner nozzle positioned in the liquid conducting channel and a switch assembly installed on the inner nozzle, and a medium channel is formed on the inner side of the inner nozzle communicating with the liquid conducting channel and the connecting channel; the switch assembly comprises at least a sealing member for closing the medium channel, and an output member connected to the sealing member and with an outer end portion extending into the connecting channel; the output member can move inward under external action to push the sealing member open to open the medium channel, or move outward under the action of an elastic reset force to drive the sealing member to close the medium channel.

[0015] In the above technical solution, a second one-way valve is arranged at the end of the liquid outlet pipe, the connecting nozzle of the one-way valve is plugged into the liquid outlet pipe, the outer side of the connecting nozzle is sleeved with a connecting sleeve, the outer inner side of the connecting sleeve forms a connecting channel connected to the tire air nozzle, a second valve core is arranged in the connecting nozzle, the second valve core includes an inner nozzle and a switch assembly arranged on the inner nozzle, a medium channel is formed in the inner nozzle to connect the liquid outlet pipe and the external channel, the switch assembly includes an output member and a sealing member, the sealing member is used to close the medium channel, the output member can move toward the liquid outlet pipe under the action of an external force to open the medium channel, and the output member can move to the outside under the action of an external force to close the medium channel. Therefore, when connected to the tire air nozzle, the air needle presses against the output member to open the medium channel to introduce the liquid into the tire, and when not connected to the tire air nozzle, the internal force restores the sealing member to close the medium channel, thereby effectively preventing the situation where the inflation pump is started first when the bottle body is not connected to the tire, and the tire repairing liquid is accidentally discharged, causing trouble for cleaning.

[0016] Preferably, the sealing member is a plug, and the output member is a push rod, the push rod is axially inserted into the inner nozzle, the plug is formed at the end of the push rod and is closed on the inner end of the inner nozzle, the outer end of the push rod extends into the connecting channel, a spring is provided on the push rod and is sleeved inside the inner nozzle, a retaining wall cooperating with the spring is provided on the side of the medium channel close to the plug, and two protrusions cooperating with the other end of the spring are provided on the push rod. When the connecting channel is connected to the outside, the push rod moves toward the liquid outlet pipe under the action of external force, the spring is compressed, and a gap is formed between the inner end of the plug extending out of the inner nozzle and the inner nozzle to connect the liquid guide channel and the medium channel.

[0017] In the above technical solution, the switch assembly is composed of a push rod, a plug and a spring. When the connecting sleeve is connected to the outside (tire nozzle), the push rod is pushed to move toward the liquid outlet pipe, the spring is compressed between the protrusion and the retaining wall, and a gap is formed between the inner end of the plug extending out of the inner nozzle and the inner nozzle to conduct the liquid channel and the medium channel, and the tire repair liquid can flow into the tire nozzle through the medium channel; when the connecting sleeve is not connected to the tire nozzle, the elastic force of the spring acts on the push rod, the push rod moves outward, the plug is reset to press against the end of the inner nozzle to close the medium channel, and the liquid can be prevented from being accidentally discharged. The protrusion can effectively compress the spring on the push rod and improve the structural strength of the push rod.

[0018] Preferably, a reinforcement block is formed on the push rod between the protrusion and the plug, and the reinforcement block is located on the inner side of the spring; a stopper is formed outwardly at the outer end of the inner nozzle, and a round block is formed on the outer side of the push rod, and a through hole is constructed in the middle of the stopper on both sides of which abut against the protrusion and the round block, and outlets communicating with the medium channel are provided on both sides of the stopper.

[0019] In the above technical solution, the setting of the reinforcing block improves the structural strength of the push rod, and at the same time, it plays a certain guiding role when the spring moves, preventing the spring from moving out of position. At the same time, the stopper cooperates with the round block to limit the push rod inward, preventing the end of the push rod from being pushed into the medium channel and unable to recover; the stopper cooperates with the protrusion to limit the push rod outward; the outlet facilitates the medium to be connected.

[0020] Preferably, a gasket is formed on the outer side of the stopper, and a stopper matched with the gasket is provided on the inner wall of the connecting channel; an inclined wall is provided in the inner circumferential direction of the liquid guiding channel, and an elastic wall matched with the inclined wall is provided in the circumferential direction on the side wall of the inner nozzle.

The cooperation between the inclined wall and the elastic wall can prevent the inner nozzle from moving toward the inside of the connecting nozzle to a certain extent, playing an axial limiting role, and the provision of the elastic wall is convenient for installation.

[0021] Preferably, a plurality of support frames are symmetrically arranged on the side wall of the bottle cap, and the upper end faces of the plurality of support frames are flush and not lower than the upper end face of the bottle cap. In this technical solution, a plurality of support frames are symmetrically arranged on the side wall of the bottle cap, and the upper end faces of the support frames are flush or exceed the upper end face of the bottle cap. When in use, the tire repair liquid bottle connected to the base-type bottle cap can be stably inverted on the ground through the support frame of the bottle cap, so that the tire repair liquid bottle and the air pump can be used separately without being mounted on the air pump, thereby reducing the influence of the vibration generated when the air pump is working on the infusion of the tire repair liquid bottle and improving the tire repair efficiency.

[0024] The support frame is a fan-shaped frame with the center of the cover body as the center of the circle, with a large support area and a stable structure, which can provide a good support effect on the cover body. In addition, the setting of the retaining edge can not only improve the strength of the support frame, but also can be used to clamp the liquid outlet pipe, reduce the packaging storage space, and improve the space utilization rate.

[0025] At the same time, the angle between the two side walls of the support frame and the center of the cover body is 120°, and the support frame has a large opening angle, so that the cover body can be more stably inverted on the ground.

[0051] In the above technical scheme, the tire repair system includes an air pump and a tire repair liquid bottle connected to each other. The liquid outlet pipe of the tire repair liquid bottle is connected to the tire. When the air pump is started, air is input into the bottle body through the air inlet pipe and the air inlet channel. The air presses the liquid into the liquid outlet channel and comes out from the liquid outlet nozzle into the liquid outlet pipe, and finally fills the tire. A first one-way valve is provided in the air inlet pipe or the air inlet channel, which is suitable for the one-way air intake of the air inlet pipe into the bottle body, so as to prevent the pressure in the tire repair liquid bottle from pressing the tire repair liquid back into the air pump when the air pump suddenly stops, thereby damaging the air pump. A second one-way valve is provided at the end of the liquid outlet pipe, which is suitable for preventing the liquid outlet pipe from discharging liquid when the liquid outlet pipe is not connected to the tire, thereby preventing the user from starting the air pump first when the liquid outlet is not connected to the tire due to negligence or improper use, which will cause the tire repair liquid to be accidentally discharged and splashed onto the tread, making it difficult to clean.

[0052] like Figures 1 to 7 As shown, the first one-way valve 10 is arranged in the air inlet channel 8, including a first valve core 12 and a sealing ball 13, a flow channel 18 is formed in the first valve core 12, the air inlet channel 8 includes a wide channel 14 and a narrow channel 15 arranged from outside to inside, a step is formed between the wide channel 14 and the narrow channel 15, the step is circumferentially extended into the wide channel 14 with a plurality of support columns 16, and a medium groove 17 communicating with the narrow channel 15 and the wide channel 14 is formed between adjacent support columns 16; the first valve core 12 is arranged in the wide channel 14, the sealing ball 13 is arranged in the accommodating cavity between the wide channel 14 and the narrow channel 15, and the diameter of the sealing ball 13 is greater than the inner diameter of the narrow channel 15; When the air inlet channel 8 takes in air, the sealing ball 13 is pushed open to make it abut against a plurality of support columns 16, and the air enters the bottle body 9 along the flow channel 18 and the medium groove 17; when the air inlet channel 8 discharges liquid, the sealing ball 13 blocks the flow channel 18, and the flow channel 18 is not connected to the medium groove 17.

[0053] In the above technical solution, the air inlet and outlet passages are configured to be wide outside and narrow inside, and a plurality of medium grooves are formed on the steps between the wide channel and the narrow channel. When air is taken in, the airflow enters the wide channel, pushes the sealing ball open through the flow channel in the first valve core, and enters the bottle cap through the medium groove, pressing the liquid in the bottle into the liquid outlet passage. When the air pump stops working unexpectedly, the liquid in the bottle enters the narrow channel under the action of pressure, pushes the sealing ball to the front end of the first valve core to seal the flow channel, thereby preventing the liquid in the bottle from flowing back into the air pump and damaging the air pump.

[0054] Furthermore, the first valve core 12 includes a main body 19 tightly matched with the inner wall of the wide channel 14 and a convex part 20 formed on the main body 19 and extending toward the narrow channel 15, and a gap is formed between the convex part 20 and the inner wall of the wide channel 14; the side wall of the main body 19 is provided with an external thread 21 tightly matched with the inner wall of the wide channel 14. In this technical solution, a gap is formed between the convex part and the inner wall of the pipeline, so that the first valve core is easier to install in the pipeline during installation, thereby improving installation efficiency. In addition, the external thread on the side wall of the main body can achieve a better sealing effect.

[0055] Furthermore, a screw-in opening 22 adapted to a screwdriver bit is provided on the outer side of the main body 19. In this technical solution, the screw-in opening on the main body of the valve core can facilitate users to use a screwdriver for screwing, which is more convenient.

[0056] like Figures 8 to 16 As shown, the second one-way valve 11 includes a connecting nozzle 23 inserted into the outlet of the liquid outlet pipe 6 and a connecting sleeve 24 partially sleeved on the connecting nozzle 23, and the other part of the connecting sleeve 24 forms a connecting channel 25 on the inner side; a liquid conducting channel 26 communicating with the liquid outlet pipe 6 and the connecting channel 25 is formed in the connecting nozzle 23, and a second valve core 27 is provided in the liquid conducting channel 26, and the second valve core 27 includes an inner nozzle 28 positioned in the liquid conducting channel 26 and a switch assembly installed on the inner nozzle 28, and a medium channel 29 is formed on the inner side of the inner nozzle 28 communicating with the liquid conducting channel 26 and the connecting channel 25; the switch assembly at least includes a sealing member for closing the medium channel 29, and an output member connected to the sealing member and having an outer end extending into the connecting channel 25; the output member can move inwards under external action to push the sealing member open to open the medium channel 29, or move outwards under the action of an elastic reset force to drive the sealing member to close the medium channel 29.

[0057] In the above technical solution, a second one-way valve is arranged at the end of the liquid outlet pipe, the connecting nozzle of the one-way valve is plugged into the liquid outlet pipe, the outer side of the connecting nozzle is sleeved with a connecting sleeve, the outer inner side of the connecting sleeve forms a connecting channel connected to the tire air nozzle, a second valve core is arranged in the connecting nozzle, the second valve core includes an inner nozzle and a switch assembly arranged on the inner nozzle, a medium channel is formed in the inner nozzle to connect the liquid outlet pipe and the external channel, the switch assembly includes an output member and a sealing member, the sealing member is used to close the medium channel, the output member can move toward the liquid outlet pipe under the action of an external force to open the medium channel, and the output member can move to the outside under the action of an external force to close the medium channel. Therefore, when connected to the tire air nozzle, the air needle presses against the output member to open the medium channel to introduce the liquid into the tire, and when not connected to the tire air nozzle, the internal force restores the sealing member to close the medium channel, thereby effectively preventing the situation where the inflation pump is started first when the bottle body is not connected to the tire, and the tire repairing liquid is accidentally discharged, causing trouble for cleaning.

[0058] Furthermore, the sealing member is a plug 30, and the output member is a push rod 31. The push rod 31 is axially penetrated on the inner nozzle 28. The plug 30 is formed at the end of the push rod 31 and is closed on the inner end of the inner nozzle 28. The outer end of the push rod 31 extends into the connecting channel 25. A spring 32 is sleeved on the push rod 31 in the inner nozzle 28. A retaining wall 33 cooperating with the spring 32 is provided on the side of the medium channel 29 close to the plug 30. Two protrusions 34 cooperating with the other end of the spring 32 are provided on the push rod 31. When the connecting channel 25 is connected to the outside, the push rod 31 moves toward the liquid outlet pipe 6 under the action of external force, the spring 32 is compressed, and a gap is formed between the inner end of the plug 30 extending out of the inner nozzle 28 and the inner nozzle 28 to conduct the liquid channel 26 and the medium channel 29.

[0059] In the above technical solution, the switch assembly is composed of a push rod, a plug and a spring. When the connecting sleeve is connected to the outside (tire nozzle), the push rod is pushed to move toward the liquid outlet pipe, the spring is compressed between the protrusion and the retaining wall, and a gap is formed between the inner end of the plug extending out of the inner nozzle and the inner nozzle to conduct the liquid channel and the medium channel, and the tire repair liquid can flow into the tire nozzle through the medium channel; when the connecting sleeve is not connected to the tire nozzle, the elastic force of the spring acts on the push rod, the push rod moves outward, the plug is reset to press against the end of the inner nozzle to close the medium channel, and the liquid can be prevented from being accidentally discharged. The protrusion can effectively compress the spring on the push rod and improve the structural strength of the push rod.

[0060] Furthermore, a reinforcing block 35 is formed on the push rod 31 between the protrusion 34 and the plug 30, and the reinforcing block 35 is located on the inner side of the spring 32; a stopper 36 is formed outwardly at the outer end of the inner nozzle 28, and a round block 37 is formed on the outer side of the push rod 31, and a through hole 38 is constructed in the middle of the stopper 36, which is abutted against the protrusion 34 and the round block 37 on both sides, and outlets communicating with the medium channel 29 are provided on both sides of the stopper 36.

[0061] In the above technical solution, the setting of the reinforcing block improves the structural strength of the push rod, and at the same time, it plays a certain guiding role when the spring moves, preventing the spring from moving out of position. At the same time, the stopper cooperates with the round block to limit the push rod inward, preventing the end of the push rod from being pushed into the medium channel and unable to recover; the stopper cooperates with the protrusion to limit the push rod outward; the outlet facilitates the medium to be connected.

[0062] Furthermore, a gasket 39 is formed on the outer side of the stopper 36, and a stopper 40 that cooperates with the gasket 39 is provided on the inner wall of the connecting channel 25; the liquid guiding channel 26 is provided with an inclined wall 41 in the circumferential direction, and an elastic wall 42 that cooperates with the inclined wall 41 is provided on the side wall of the inner nozzle 28 in the circumferential direction. In this technical solution, the setting of the gasket enables the outer end of the inner nozzle to better cooperate with the stopper to play an axial limiting role, while improving the structural strength of the stopper. The cooperation of the inclined wall and the elastic wall can prevent the inner nozzle from moving toward the inside of the connecting nozzle to a certain extent, playing an axial limiting role, and the setting and installation of the elastic wall are convenient.

[0063] like Figure 1 , Figure 3 as well as Figures 17 to 19 , a plurality of support frames 43 are symmetrically arranged on the side wall of the bottle cap 3, and the upper end faces of the plurality of support frames 43 are flush and not lower than the upper end face of the bottle cap. In this technical solution, a plurality of support frames are symmetrically arranged on the side wall of the bottle cap, and the upper end faces of the support frames are flush or exceed the upper end face of the bottle cap. When in use, the tire repair liquid bottle connected to the base-type bottle cap can be stably inverted on the ground through the support frame of the bottle cap, so that the tire repair liquid bottle and the air pump can be used separately without being clamped on the air pump, which reduces the influence of the vibration generated when the air pump is working on the infusion of the tire repair liquid bottle and improves the tire repair efficiency.

[0064] Further, two support frames 43 are symmetrically provided; the support frame 43 is a fan-shaped frame with the center of the bottle cap 3 as the center; the outer edge of the lower end of the support frame 43 is downwardly formed with a retaining edge 44, and the liquid outlet pipe 6 can be arranged between the retaining edges 44 on both sides; the angle formed by the side walls of the support frame 43 and the center of the bottle cap 3 is 120°; The inner side of the bottle cap 3 is provided with a pressing ring 45 that cooperates with the bottle mouth of the bottle body 9, and a groove 46 corresponding to the bottle mouth is formed in the pressing ring 45. The groove 46 is connected to the air inlet channel 8 and the liquid outlet channel 47. An opening column 48 extending out of the groove 46 is provided on the bottom surface of the groove 46, and the lower end surface of the opening column 48 is a beveled surface.

[0065] In the above technical solution, two support frames are symmetrically provided, which can not only meet the support effect for the cover body, but also reduce material costs.

[0066] The support frame is a fan-shaped frame with the center of the cover body as the center of the circle, with a large support area and a stable structure, which can provide a good support effect on the cover body. In addition, the setting of the retaining edge can not only improve the strength of the support frame, but also can be used to clamp the liquid outlet pipe, reduce the packaging storage space, and improve the space utilization rate.

[0067] At the same time, the angle between the two side walls of the support frame and the center of the cover body is 120°, and the support frame has a large opening angle, so that the cover body can be more stably inverted on the ground. The perforated column is convenient for piercing the aluminum foil seal of the bottle body, and the aluminum foil seal of the bottle body can improve the sealing of the tire repair liquid, and the bottle cap and the bottle body can be stored separately, which is more convenient.

[0068] It is also necessary to explain here that The support frame is provided with fan-shaped holes 50 to reduce material cost.

[0069] A sealing gasket 51 is provided between the pressing ring and the inner wall of the cover body, and the sealing gasket plays a sealing role between the bottle cap and the bottle body to prevent liquid leakage.

[0070] The inner wall of the bottle cap is threadably connected to the bottle mouth.

[0071] The air inlet nozzle and the liquid outlet nozzle are symmetrically arranged on the side wall of the cap body, and an indicator groove 52 is formed on the upper end of the bottle cap, and an indicator arrow 53 is arranged in the indicator groove 52, and the arrow end of the indicator arrow 53 faces the liquid outlet nozzle, and the side walls of the air inlet nozzle and the liquid outlet nozzle are provided with connecting threads 54. Since the two nozzles have the same appearance, but the terminal diameter of the air inlet channel is small, and the initial port diameter of the liquid outlet channel is relatively large, it is very convenient to identify the air inlet nozzle and the liquid outlet nozzle by setting the indicator arrow; and the threads on the air inlet nozzle and the liquid outlet nozzle are used to be tightly matched with the threads of the air inlet pipe and the liquid outlet pipe respectively.

[0072] The outer wall of the connecting sleeve is provided with a plurality of anti-skid rings 55. The provision of the anti-skid rings makes the one-way valve more convenient to install and is not easy to slip.

[0073] The front part of the inner mouth is sleeved with a sealing ring 56, and the plug abuts against the sealing ring when it is closed at the front end of the inner mouth 6. Since the plug and the inner mouth are detachable, the sealing ring at the front end of the inner mouth improves the sealing effect and prevents liquid from leaking.

[0074] The front part of the connecting nozzle is formed with a plurality of connecting steps 57 and is tensionedly arranged in the liquid pipe. The front part of the connecting nozzle is formed with a plurality of connecting steps and is tensionedly arranged in the liquid pipe, so that the connection is more firm, not easy to be disengaged and has good sealing performance.

[0075] In this specific embodiment, there are problems with the use of the existing air pump and tire repair liquid bottle: ① If the air pump stops suddenly, the pressure in the tire sealant bottle will push the sealant back into the air pump, damaging it.

[0076] ② If the user is negligent or uses it improperly and starts the air pump before the liquid outlet is connected to the tire, the tire sealant will be accidentally discharged and splash onto the tread. The lumps formed after the tire sealant solidifies may cause vehicle instability when driving at high speeds, and even require the tire to be disassembled for cleaning, which is extremely troublesome.

[0077] ③. The tire sealant bottle cannot be placed directly on a flat surface. It is usually inverted and mounted on the air pump through the bottle cap for tire repair. In this way, the vibration generated by the air pump is directly transmitted to the bottle body, causing the tire sealant inside to continue to shake, affecting the delivery efficiency of the tire sealant.

[0078] The above scheme prevents the tire repair fluid from flowing back into the air pump and damaging the air pump by setting a first one-way valve in the air inlet channel of the bottle cap. A second one-way valve is set at the end of the liquid outlet pipe to prevent the liquid from accidentally spraying out when it is not connected to the tire. At the same time, a support frame is formed on the bottle cap so that the bottle cap can be inverted and stand upright on the ground and used separately from the air pump, which reduces the impact of the vibration generated by the air pump when working on the infusion of the tire repair fluid bottle and improves the tire repair efficiency.
