Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a tire repair solution can, particularly to one usable to be stand normally or inversely, with its repair solution to be pumped into a tire by means of an air compressor, possible to save time and labor as well. In addition, a spare one-way air valve and its tool are stored on a cap for convenience of operation.

2. Description of the Prior Art

A conventional automatic tire repair solution is applied to various types of vehicle tires, having a function of preventive and automatic tire repair. However, in using a spray-mode tire repair solution, a nozzle of a solution can is connected to the air valve of a tire, and then the solution is pumped into the tire to be repaired by compressing repeatedly the nozzle. But in compressing with a finger, its manual force is not strong, so the solution to be pumped into the tire may not be enough for repairing, far from achieving actual repair to the tire. Moreover, the solution can is commonly impossible to be inverted in use, so if the air valve is not properly situated, it is impossible to perform repair.

SUMMARY OF THE INVENTION

The purpose of the invention is to offer a tire repair solution can usable in a normal position and an inverted position, in conjunction with an air compressor for forcefully pushing tire repair solution into a tire to be repaired with time and labor saved largely.

Another purpose of the invention is to offer a tire repair solution can having a spare one-way air valve and its tool for taking place a one-way air valve fitted in an intake of a can body in case of out of order.

The feature of the invention is a body provided with a hole and a cap combined with the hole. The cap is provided with an intake, an outlet, a guide tube extending from the underside into an interior of the body. Further a suction tube is connected with a lower end of the guide tube in the body, and an exterior tube is connected to the intake and an air compressor at the same time. The intake has a one-way air valve fitted in, and the guided tube has a hole in its wall and closed by a slide block fitted on the hole. The outlet has a back-pressure valve fitted in. Thus, the air compressor can forcefully push compressed air through the intake and then into the body so that tire repair solution in the body may be forced to flow through an air valve of a tire by the compressed air for repairing the tire. Further the slide block is possible to slide down to open the through hole for the repair solution to flow through and then out of the outlet to finally into a tire to be repaired in case the tire repair solution can is inverted for use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A tire repair solution can in the present invention, as shown in FIGS. 1, 2 and 3, includes a body 1, and cap 2 as main components.

The body 1 is provided with a hole in an upper side for combining with the cap 2.

The cap 2 is provided with an intake 20 at the front end, an outlet 21 formed at a rear end, a guide tube 22 extending down from an intermediate portion into the interior of the body 1. Then an exterior tube 3 is connected with the intake 20 at one end and also connected with an air compressor at the other end so that compressed air may be forced to flow into the body 1. An inlet air passage 200 is formed to communicate with both the intake 20 and the interior of the body 1, having its outer end connected with a one-way air valve 23 and its inner end provided with a stop block 24. The guide tube 22 has a guide passageway 220 and a hole 221 formed in an intermediate wall and closed up by a slide block 26 fitted closely thereon. Further, a back-pressure valve 210 is tightly fitted in the outlet 21, with a valve cap 211 covered on the outer surface of the back-pressure valve 210. The valve cap 211 has a flow hole 212 to be connected with a connect tube 4, which has its end assembled with a joint 41. Then the joint 41 can be connected to an air valve of a tire so that the tire repair solution in the body 1 may flow into a tire to be repaired by means of the air compressor.

Moreover, the cap 2 is provided with a recess 27 in the upper surface for receiving a spare one-way air valve 5, and an upper cap 270 is covered on the recess 27 with the one-way air valve 5. Further, an air valve tool 6 is attached at one side of the cap 2 for releasing the one-way air valve 23 in case of out of order, and a stop plate 28 is fixed at a side of the cap 2 for the connect tube 4 to be positioned after the connect tube 4 is wound around the cap 2.

In using, referring to FIG. 4, when a tire is found to leak, the exterior tube 3 connected with the inlet 20 of the cap 2 is connected with an air compressor, and then the connect tube 4 connected to the outlet 21 is connected to the air valve of the tire. Then the air compressor is started to send compressed air into the body 1, and the compressed air flows through the inlet 20 and the one-way air valve 23 into the inlet air passageway 200, forcing open the stop block 24 to move into the interior of the body 1. Then the air repair solution (B) in the body 1 gives rise to foaming and flows through the suction tube 25 into guide tube 22, pushing open the back-pressure valve 210 to flow through the flow hole 212 of the outlet 21 into the connect tube 4 and then into the tire to block up the leak point of the tire.

In addition, FIG. 5 shows the tire repair solution can is used in the inversed condition, with the slide block 26 sliding down along the guide tube 22 to let the hole 221 not closed by the slide block 26, so the tire repair solution (B) may flow through the hole 221 into the flow passageway 220, and finally into the tire.

As to the air valve tool 6, it is used for taking off the one-way air valve 23 from the intake 20 with easiness, and the spare one-way air valve 5 can take place of the one-way air valve 23 in case of out of order.

The tire repair solution can in the invention has the following advantages as can be seen from the foresaid description.

1. The can body 1 can be positioned normally or inversely. In the normal position, the repair solution flows through the guide tube 22 into a tire, while in the inverted position, it flow from the hole 221 into the flow passageway 220 and then into the tire, by means of an air compressor forcefully pushing the repair solution (B) into a tire with the time and labor saved largely.

2. A spare one-way air valve 5 and its tool 6 are attached with the cap 2 for replacing the one-way air valve 23 when the one-way air valve 23 is lost or destroyed.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall into the spirit and scope of the invention.
