Description

  The present invention relates to a vehicle-mounted air compressor, and in particular, includes a case with a built-in air compressor, and an intake end pipe of a lid of a repair container can that contains an adhesive liquid is coupled to an exhaust manifold of the air compressor In the intake end pipe, a first flexible wire extending to the top end of the pipe connected to the inner wall of the lid is arranged, and a series-connected flexible pipe is coupled to the adhesive liquid take-out pipe of the lid A second flexible wire extending to the valve base is disposed in the adhesive liquid take-out tube, and a plug provided at the upper end of the tube is pushed open by the first flexible wire through the exhaust manifold. When the second flexible wire is pushed by the series-connected flexible pipe, the valve ring is discharged directly downward through the pipe body without passing through the adhesive liquid and presses the upper surface of the adhesive liquid. Is pushed open, adhesive liquid take-out pipe and series connection flexi The Le tube, is adhered liquid injected into the punctured valve of the tire, safety and efficient vehicle air compressor or to inject air into the tire or repairing a punctured tire.

  A conventional air compressor that repairs tire puncture or injects air into the tire has a built-in air compressor that compresses air, an independent repair container can that contains adhesive liquid, Two series-connected flexible tubes.

The intake end pipe 31 of the lid 3 is locked to the exhaust manifold 15 of the air compressor 13, and the first adapter 71 of the series-connected flexible pipe 7 is locked to the adhesive liquid extraction pipe 32 of the lid 3, When repairing a tire puncture or injecting air into the tire, the second adapter 72 of the series-connected flexible tube 7 is screwed into the tire valve 8 to supply power to the case 1 from an automobile or other DC power source. Then, the adhesive liquid 20 accommodated in the repair container can 2 is pressed by the air supplied from the air compressor 13 and injected into the punctured tire 81 through the series connection flexible tube 7. The puncture can be repaired or air can be injected into the tire 81.

  Reference is made to FIGS. As shown in FIGS. 4 to 8, the repair container can 2 of the on-vehicle air compressor of this embodiment has a hollow shape and a chamber 23 that accommodates the adhesive liquid 20 and has an open end 21. The open end 21 has a neck chamber 24 formed on the inner diameter wall, and the lid 3 is screwed to the outer diameter. The lid 3 is provided with a tube 6 having a long passage 65 on the inner wall. An open end 61 provided at the other end of the tube body 6 is sealed with a plug 60. A valve base 62 of an annular groove 621 is provided on the inner wall of the lid provided on the outer periphery of the bottom end of the tube body 6, and a passage 64 is provided in the annular groove 621. A valve ring 63 made of a rubber material is installed on the annular groove 621 of the valve base 62, and the passage 64 of the annular groove 621 is sealed by the valve ring 63. An intake end pipe 31 and an adhesive liquid take-out pipe 32 are provided outside the lid 3. The intake end pipe 31 has an inner passage 310 and communicates with the long passage 65 of the pipe body 6 described above. The first flexible wire 4 (see FIG. 5) having an appropriate length has a first tip head 41 and a second tip head 42. The first tip head portion 41 includes a front protruding end 410, a plurality of bumps 411 that are spaced apart from each other, and a flow groove 412 that is recessed between the two bumps 411. The first flexible wire 4 is disposed so as to extend into the inner passage 310 of the intake end pipe 31 and the long passage 65 of the pipe body 6. The second tip head portion 42 may be a plug 60 that seals the end portion of the tube body 6. The first tip head 41 is provided at the inlet 311 of the intake end pipe 31. The adhesive liquid take-out pipe 32 has an inner passage 320, communicates with the passage 64 of the annular concave groove 621 provided in the valve base 62, and the second flexible wire 5 is provided in the adhesive liquid take-out pipe 32. (See FIG. 6). The second flexible wire 5 has a first tip head 51 and a second tip head 52. The second tip head 52 is brought into contact with a valve ring 63 provided in the annular groove 621. The first tip head 51 has an outer ring 512. The inner ring portion of the outer ring 512 is provided with pillars 510 connected to each other and a plurality of bumps 511 arranged at intervals. A flow groove 513 is formed between the bumps 511 arranged at intervals. When the lid 3 and the repair container can 2 are joined, the lid 3 is screwed into the opening end 21 of the repair container can 2 by the packing ring 33, and high stability and sealing performance can be obtained.

  The front end port of the exhaust manifold 15 of the air compressor 13 has a firing needle 151. When the exhaust manifold 15 is coupled to the intake end pipe 31 of the lid body 3, the front protrusion end 410 provided on the first tip head portion 41 of the first flexible wire body 4 described above becomes air The plug 13 on the open end 61 of the tube body 6 is removed by the second tip head portion 42 of the first flexible wire 4 by being pushed and moved by the firing needle 151 of the exhaust manifold 15 of the compressor 13. (See FIG. 7), compressed air enters through the flow groove 412, flows through the inner passage 310 and the long passage 65 of the tube body 6, and enters the clearance space M 0 of the repair container can 2 from the open end 61 of the tube body 6. Supplied. In this process, since the output compressed air acts directly on the upper surface of the adhesive liquid 20 without passing through the adhesive liquid 20 in the repair container can 2, there is almost no resistance.

  When repairing the puncture of the tire 81, the first adapter 71 of the serial connection flexible pipe 7 is coupled to the adhesive liquid take-out pipe 35 of the lid 3, and the first adapter 71 of the series connection flexible pipe 7 is connected to the adhesive liquid take-out pipe. 35, the first tip head portion 51 of the second flexible wire body 5 in the inside 35 is pushed and moved so that the valve ring 63 is annularly recessed by the second tip head portion 52 of the second flexible wire body 5. The adhesive liquid 20 is pushed out of the groove 621 and enters the valve 8 through the passage 64, the inner passage 320 and the passage 73 of the series-connected flexible pipe 7.

  The adhesive liquid 20 used for repairing the punctured tire 81 is stored in the chamber 23 of the repair container can 2 described above. The initial storage height of the repair container can 2 in which the adhesive liquid 20 is stored is L0 (see FIG. 8). The repair container can 2 has an open end 21 provided at the bottom and a bottom wall 22 provided at the top. In use, a slight space is left between the initial accommodation height L0 of the adhesive liquid 20 and the bottom wall 22 (hereinafter referred to as “gap space M0”). One of the main features of the present invention is that the height L1 of the tube body 6 in the chamber 23 is higher than the initial accommodation height L0 of the adhesive liquid 20 in the chamber 23. With such a configuration, the compressed air of the air compressor 13 directly enters the gap space M0 occupied by the adhesive liquid 20 in the above-described repair container can 2 through the long passage 65 of the tube body 6, and the air When the upper surface of the adhesive liquid 20 is pressed by the pressure, the adhesive liquid 20 flows out from the adhesive liquid take-out pipe 32.

  Thus, the system of the present invention is different from the prior art. In the prior art, since the pressure of the air is directed upward from the bottom of the adhesive liquid 20, exits the upper surface of the adhesive liquid 20, presses the adhesive liquid 20, and is discharged from the adhesive liquid take-out pipe 32. It is necessary to overcome the extra resistance. Further, when the viscosity of the adhesive liquid 20 is high or when used in an extremely cold region, it may take a long time for the air to pass through the adhesive liquid 20, but the present invention repairs tire punctures. The time required to inject air into the tire can be greatly reduced, and the convenience of operation can be improved.

  Please refer to FIG. 7 and FIG. As shown in FIGS. 7 and 8, the repair container can 2 uses the connection relationship between the intake end pipe 31 of the lid 3 and the exhaust manifold 15 of the air compressor 13, or is connected in series with the adhesive liquid take-out pipe 32. The connection relationship between the connection flexible tube 7 and the first adapter 71 may be used. When repairing punctures by injecting adhesive liquid into the tire or injecting air into the tire, air generated in the air compressor 13 enters the inner passage 310 of the intake end pipe 31 of the lid 3 from the exhaust manifold 15. When the inner passage 310 and the long passage 65 of the tubular body 6 are in communication with each other and the plug 60 on the open end 61 of the tubular body 6 is pushed by the first flexible wire body 4 and removed, it enters the gap space M0. Pressure is directly applied to the upper surface of the adhesive liquid 20 by the air, and the adhesive liquid 20 passes through the neck chamber 24 of the open end 21 and is connected to the first adapter of the series-connected flexible pipe 7 by the second flexible wire 5. 71 is pushed open and is brought into contact with the valve ring 63 on the passage 64 of the valve base 62, and the valve ring 63 is pressed against the neck chamber 24. At this time, the adhesive liquid 20 flows out from the gap formed between the valve ring 63 and the neck chamber 24, and flows from the inner passage 320 of the adhesive liquid take-out pipe 32 into the first adapter 71 of the serial connection flexible pipe 7. (See FIGS. 7 and 8). Then, the adhesive liquid 20 enters the series-connected flexible tube 7 from the first adapter 71, and then enters the tire 81 via the second adapter 72 (see FIG. 2).

  Please refer to FIGS. As shown in FIGS. 9 to 11, an in-vehicle air compressor according to another embodiment of the present invention is provided with an adhesive liquid take-out pipe 35 on the outer ring side of the lid 3. An intake end pipe 34 is provided on the top wall of the lid 3 perpendicular to the adhesive liquid take-out pipe 35. The inner passage 340 of the intake end pipe 34 and the long passage 65 of the pipe body 6 are linear, and the first flexible wire 4 provided in the intake end pipe 34 is connected to the long passage 65 of the pipe body 6. Therefore, when the present invention is commercialized and manufactured, the manufacturer can change the direction in which the product is installed as necessary.

  As can be seen from the above, the structure of the present invention is not only different from the conventional apparatus, but also has novelty, and the pressure of the air generated by the air compressor 13 causes the adhesive liquid 20 in the repair container can 2 to flow. By making the pipe body 6 higher than the water level, it is not necessary to overcome the resistance force that is generated when the air pressure passes upward from the inside of the adhesive liquid 20, and the repair container can directly passes through the pipe body 6. The operation time can be greatly shortened because it reaches the gap space M0. Further, the exhaust manifold 15 of the air compressor 13 directly pushes off the plug 60 on the open end 61 of the tube body 6 via the first flexible wire body 4, and the second flexible wire body 5. Accordingly, when the first adapter 71 of the series-connected flexible pipe 7 is directly pushed open and brought into contact with the valve ring 63 on the passage 64 of the valve base 62, the adhesive liquid 20 is allowed to flow between the valve ring 63 and the neck chamber 24. In this case, the present invention has an inventive step and satisfies the patent requirement because it flows into the punctured tire 81 after flowing from the inner passage 320 of the adhesive liquid take-out pipe 32 to the series-connected flexible pipe 7. Is obvious.

  While the preferred embodiments of the present invention have been disclosed above, as may be appreciated by those skilled in the art, they are not intended to limit the invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
