The front and rear orientation of the present invention is defined as follows: in the case where the air compressor supplies air into the tire repair glue bottle, the orientation of the air compressor is the rear, and the orientation of the glue bottle is the front.

As shown in FIG. 1-8C, the pneumatic pressure-filling glue bottle of the present invention comprises a bottle body 1 for accommodating glue, the bottle body 1 is provided with a glue opening 11 and an air inlet hole 4, and the bottle opening 11 is provided with a bottle cap. 2. The intake port 12 is connected to a straight pipe member 5 which is inserted into the bottle body 1 and transmits air to the bottle body 1. The gas inlet pipe 6 for transferring air to the straight pipe member 5 is connected to the intake end of the straight pipe member 5. The gas hose 6 is provided with an explosion-proof member 7 for preventing the explosion of the bottle body 1. A capping tube is disposed in the cap 2; the capping tube includes a first tube segment 21 disposed along the axial direction of the bottle body 1 and a second tube segment 22 disposed perpendicular to the first tube segment 21. The tail section 222 of the second pipe section 22 communicates with the glue throat 3 to direct the glue in the bottle to the tire. A first step 25 is provided at the inlet 211 of the first pipe section 21, and a pipe wall between the inlet 211 of the first pipe section 21 and the inlet 221 of the second pipe section 22 is provided with a second step 26, in the first pipe section A rubber plug 24 is disposed between the inlet 211 of the 21st and the second step 26; the communication between the second pipe section 22 and the first pipe section 21 is between the second step 26 and the trailing end 212 of the first pipe section 21.

Through the above structure, under the action of the air generated by the air compressor, the gas throat pipe 6, the straight pipe component 5, the bottle cap 2 (especially the rubber hose tube in the bottle cap 2) and the glue throat pipe 3 form a passage, in the bottle body 1 The glue flows out to the tire through the bottle cap 2 and the glue throat pipe 3, and at the same time, after the glue is used up, the tire can be supplemented with a certain amount of air; in addition, when the pressure in the bottle body 1 is too large, the gas The explosion-proof member 7 in the throat 6 can automatically communicate with the atmosphere to lower the high pressure in the bottle 1.

Referring to Figure 3, the straight tube member 5 of the present invention includes a straight tube connector 52, a first straight tube 53 and a second straight tube 54 which are sequentially connected; the straight tube connector 52 is the inlet end of the straight tube member 5; The tube gasket 51 is located at the open end of the second straight tube 54, i.e., the outlet end of the straight tube member 5. In order to ensure the airtightness of the straight pipe member 5, the straight pipe air ring 55 may be fixed between the screwed straight pipe joint 52 and the first straight pipe 53, and at the same time, the first straight pipe 53 and the second straight pipe 54 A straight pipe gasket 51 for preventing leakage of glue in the bottle body 1 is provided at the joint. Here, the straight tube gasket 51 and the straight tube sealing ring 55 are both O-rings. Further, in another embodiment, a straight tube sponge 56 is provided in the first straight tube 53. When the air generated by the air compressor enters the straight pipe member 5, the air first passes through the straight pipe sponge 56 and then enters the second straight pipe 54, and the straight pipe sponge 56 can prevent the glue from flowing to the gas throat when the pneumatic tire filler bottle is inverted. In the tube.

The explosion-proof member 7 provided in the gas pipe 6 is a key structure for ensuring the safety of the tire-filled glue bottle of the present invention. In FIG. 4-5B, the explosion-proof member 7 includes a rear housing 71, a front housing 72 coupled to the rear housing 71, and a tapered piston 73 movably coupled to the rear housing 71. The rear housing 71 is provided with a gas release at the end. The hole 711 is provided with a spring 74 in the front housing 72. One end of the spring 74 is placed in the cavity of the front housing 72 matching the shape of the spring 74, and the other end is sleeved with the end cylinder 731 on the tapered piston 73. A lock washer 76 is fixedly mounted between the housing 71 and the front housing 72, and the lock washer 76 has an exhaust groove 761. Wherein, the lock washer 76 is integrally formed with the rear case 71. In addition, the lock washer 76 is provided with an annular groove, and an O-ring 762 is disposed in the annular groove. When the explosion-proof member 7 is assembled, a sealing gasket 77 is further disposed between the front housing 72 and the lock washer 76 to seal the front housing 72 and the lock washer 76; The gap of the groove 761 is subsequently used to release the gas. The process of inflating and exhausting the explosion-proof member 7 is as follows: when the compressor is in operation, the cone-shaped piston 73 compresses the spring 74 under the action of air pressure, and the tapered piston 73 moves to the front housing 72, so that the gas release hole 711 is thus tapered. The piston 73 is blocked, and the air can thus enter the pressure reducing valve from the rear casing 71 through the groove on the surface of the tapered piston 73 and finally enter the bottle body 1 at this time, only a trace amount of gas is discharged from the gas release hole; When the pressure in the body 1 is too large, the spring 74 moves against the tapered piston 73 in the direction of the rear housing 71 until the gas release hole 711 is no longer blocked, and the air can pass through the gas release hole 711 through the exhaust gas on the lock washer 76. The tank 761 is discharged.

The position of the explosion-proof member 7 in the gas hose 6 is not limited, and its installation position does not affect its implementation effect. In another embodiment, the explosion-proof member 7 is adjacent to the gas hose 6 and the inlet end of the straight tube member. The connection portion; the explosion-proof member 7 can also be located in the middle of the gas pipe 6. The working process of the explosion-proof member 7 at different positions is the same as the working principle, and will not be repeated here.

In the present invention, the rubber plug 24 can be moved within the first pipe section 21 according to the pressure change in the bottle body 1 to block or allow the glue port to be opened as needed. As shown in FIG. 8A, in the normal temperature and normal pressure state, the rubber plug 24 is located between the inlet 211 of the first pipe section 21 and the second step 26, that is, the position a. At this time, the rubber plug 24 blocks the glue outlet, and the glue in the bottle body 1 cannot flow out. As shown in FIG. 8C, when the compressor is in operation, the pressure inside the bottle body 1 suddenly increases, and the rubber plug 24 moves between the communication between the second pipe section 22 and the first pipe section 21 and the end end 212 of the first pipe section 21 ( At position c), the first pipe section 21 and the second pipe section 22 form a passage, and the glue can flow from the bottle body 1 through the glue pipe through the glue pipe 3 to the tire damage. In this way, the glue supply to the damaged portion of the tire can be realized by changing the air pressure in the bottle body 1 to perform tire repair. The operation process is simple and convenient, and is convenient for promotion and implementation.

In addition to this, a first step 25 and a second step 26 are provided in the first pipe section 21 between the inlet 211 and the inlet 211 of the second pipe section 22, respectively. When the ambient environment changes and the temperature inside the bottle 1 rises and the glue expands, the rubber plug 24 can move within the first pipe segment 21, but is ultimately limited by the setting of the second step 26, and the maximum moving distance is from The inlet 211 of the first pipe section 21 moves to the second step 26 (at position b) and eventually to the second step 26 (as shown in Figure 8B). When the ambient environment changes and the temperature inside the bottle 1 decreases and the bottle body 1 contracts, the rubber plug 24 is caught at the first step 25 without being moved into the bottle body due to external pressure, causing the glue to leak. Therefore, the arrangement of the first step 25 and the second step 26 ensures that when the glue bottle containing the glue is stored under extreme environmental conditions, the glue bottle is not leaked and other damage due to changes in ambient temperature.

Further, as shown in FIGS. 2 and 7, a neck tube 12 is provided at the opening of the bottle body 1, and an external thread is provided on the neck tube 12. A receiving chamber 27 is provided on the bottle cap 2, and an inner thread adapted to the external thread is provided on the inner wall of the receiving chamber 27. The first pipe section 21 of the rubber hose is disposed in the accommodating cavity 27, the gasket 23 is disposed between the neck pipe 12 and the top surface of the accommodating cavity 27, and the end of the neck pipe 12 is pressed against the gasket 23; thus, during operation, it can be prevented The glue flows out from the connection gap between the bottle body 1 and the bottle cap 2. The first end 21 of the first tube section 21 extends to the top of the receiving chamber 27, and the second section 22 is embedded in the top 271 of the receiving chamber 27. Here, the top surface and the top portion refer to the portion of the accommodating chamber 27 corresponding to the top of the bottle cap 2.

As described above, the working principle of the pneumatic pressure-filled glue bottle of the present invention is as follows: State 1: Before the tire repair, the pneumatic tire filler bottle is installed upside down in the air compressor, and the air compressor is not working; at this time, the straight pipe gasket 51 at the outlet end of the straight pipe member 5 is blocked to ensure the glue in the bottle body 1. The rubber plug 24 disposed in the cap is located at the opening of the first pipe section 21, so that the glue in the bottle body 1 does not flow out into the glue pipe 3 through the cap; State 2: During the normal tire repair process, the glue throat pipe 3 is connected with the tire valve core to be repaired, the air compressor starts to work, the gas release hole 711 of the explosion-proof member 7 is blocked, and the air generated by the air compressor passes through the gas. The throat pipe 6 enters the straight pipe member 5 and punches the straight pipe gasket 51 at the outlet end of the straight pipe member 5; at this time, the pressure inside the bottle body 1 increases, and the pressure is continuously increased to move the rubber plug 24 in the bottle cap 2 to At the end of the first pipe section 21, the glue in the bottle body 1 thus flows through the rubber hose of the bottle cap 2 and through the glue pipe 3 into the tire, while inflating the tire to a certain pressure through the above passage; State 3: If an abnormal condition occurs during the tire repairing process, specifically, when the tire spool is clogged or cannot open the rubber plug 24 in the cap, the air generated by the air compressor continues to enter the bottle body 1, resulting in the bottle body The pressure in 1 is too large; at this time, the gas release hole 711 of the explosion-proof member 7 is no longer blocked, and the gas can be discharged through the gas release hole 711 through the exhaust groove 761 on the lock washer 76, thereby reducing the excessive inside of the bottle body 1. pressure; State 4: After the tire repair is completed (or after the tire is interrupted due to abnormal conditions), the glue hose 3 is detached from the tire valve core, and the tire repair operation is terminated or interrupted.

In the third state, there may be another abnormal condition, that is, after the air compressor starts working, the generated air cannot punch the straight pipe gasket 51 at the outlet end of the straight pipe member; at this time, the pressure in the bottle body 1 is not affected. The high pressure of the straight pipe element and the gas pipe 6 will cause the gas release hole 711 of the explosion-proof member 7 to be no longer blocked, and the gas can be discharged through the gas release hole 711 through the exhaust groove 761 on the lock washer 76, which can also be avoided. The danger of a high pressure in the straight pipe element and the gas pipe 6 may be caused.

Since the present invention is a pneumatic pressure-filled glue bottle, the airtightness of the entire device is required to be high, and the present invention has the following structure for improving the airtightness of the device: (1) the straight pipe connector 52 is stuck in the air inlet hole After 4, the sealant is filled in the gap between the two; (2) the straight pipe joint 52 is screwed with the gas pipe 6, and a gasket is arranged between the two; (3) the straight pipe joint 52 and A straight tube sealing ring 55 is disposed between the first straight tubes 53.

On the other hand, since the pneumatic pressure-filled glue bottle of the present invention is installed upside down in the air compressor, it is necessary to ensure the sealing property of the cap 2 of the inverted glue bottle, specifically including the following structure: (1) the neck tube 12 and the accommodation A gasket 23 is disposed between the top surfaces of the chambers 27; (2) a rubber plug 24 is used to enhance the sealing of the guide tubes in the caps 2.

In addition, a locking ring 28 is provided at the junction of the rubber hose and the glue hose 3, and one end of the glue hose 3 is snapped into the locking ring 28 to be fixedly connected to the bottle cap 2. The design of the locking ring 28 helps to enhance the tightness of the connection between the cap 2 and the glue throat 3, preventing the glue from leaking out of the gap between the two. The other end of the glue throat 3 (i.e., the end at which the cap 2 is attached) is provided with a tire mouth 31 to be connected to the tire to be repaired.

In summary, the pneumatic pressure-filled glue bottle of the present invention can make the glue flow into the tire under the action of air on the one hand, and complete the tire repair; on the other hand, when the pressure inside the glue bottle is too large, Explosion-proof parts can communicate with the atmosphere, effectively reducing the high pressure in the bottle and ensuring the safety of the glue bottle. Further, the sealing property of the present invention is good, and there is no problem that the tire sealing efficiency is low due to leakage of glue or air leakage.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalents, and improvements made within the spirit and scope of the present invention are intended to be included in the scope of the present invention.
