A perforation 123 is provided on the periphery of the convex piece 121, and the periphery of the advance valve 12 is adhered and fixed in the advance valve chamber 111. The fitting lid 124 in which the air hole 125 is provided at the center can control the opening and closing of the air hole 125 by the leakproof convex body 122.

The pump 13 is a plastic hollow body that automatically recovers its original state. The cover pipe 131 is extended to the side and the air pipe 113 of the main body 10 is connected. The air supply valve 14 is a plastic thin plate that extends the convex piece 141 toward the center at the inner edge of the annular plate, and a leak-proof convex body 142 is provided on the convex piece 141. A perforation 143 is provided on the periphery of the convex piece 141, and the periphery of the air supply valve 14 is adhered and fixed in the air supply valve chamber 112. A fitting cover 144 extending the convex piece 145 toward the center at the inner edge of the annular plate can control the flow of the gas in the pump 13 to the air supply valve chamber 112 by the leakproof convex body 142.

[0005] The air vent valve 15 is a plastic thin plate extending the convex piece 151 toward the center at the inner edge of the annular plate, and a leak-proof convex body 152 is provided on the convex piece 151. A perforation 153 is provided on the periphery of the convex piece 151, and the periphery of the air release valve 15 is adhered and fixed in the air release valve chamber 115.

[Problems to be Solved by the Invention] However, since the above-mentioned conventional air tube charging device performs charging by a pressing method, it cannot be charged by a method of blowing directly from a mouth, which is convenient for use. Is low. In addition, many component parts are adhered and many fixing operations are performed, so that the assembling work is complicated, the working time is lengthened, and the cost is inevitably increased. In addition, since the convex body 152 of the air release valve 15 protrudes outside the air tube bag 16, if it is inadvertently pressed during use, air may escape. In addition, it is necessary to overcome the elastic design of the protrusions 142 and 152 of the air supply valve 14 or the air release valve 15 when advancing or bleeding air. If the elasticity is too large, the above operation cannot be achieved, and If it is too small, the sealing function cannot be achieved.

In order to solve the above-mentioned drawbacks of the conventional structure, an object of the present invention is to provide an air tube charging device described below. It can be directly inflated by blowing air into the mouth, which is convenient for use.

In addition, it has excellent practicality by using a combination of two types, a pressing type and a mouth blowing type.

In addition, it eliminates the danger of inadvertent air leakage, with the arc-shaped pressing piece for air bleeding hidden in the body and aligned with the body end face. Furthermore, it is easy and smooth for both the inhalation and the air bleeding operation, and the sealing effect can be surely ensured.

The length of the penetrating fitting portion 82 is larger than the length of the penetrating fitting hole 4311 of the main body 40, and the extension portion 84 is connected to the end of the engaging coupling portion 83.

The pump 90 is a plastic hollow body that automatically recovers its original state, and has a cover pipe 91 extending on one side. Next, as shown in FIGS. 18 and 19, when assembled, the extended portion 74 of the air supply valve 70 penetrates the penetration fitting hole 4211 of the isolation plate 421 of the main body 40, and the extended portion 74 is appropriately pulled. With this, the engagement portion 73 of the air supply valve 70 is stopped. The engagement coupling portion 73 adjusts its own elasticity to the distal conical shape, and forcibly passes through the penetration fitting hole 421 1 of the isolation plate 421, and at the same time, the penetration fitting portion 72 of the air supply valve 70 connects the isolation plate 421. Is inserted into the through-hole 4211 to exhibit a movable state. Subsequently, the stretched portion 74 is cut.

The extension portion 64 of the air advance valve 60 penetrates and fits into the penetration fitting hole 511 of the isolation plate 51 of the cover lid 50, and stops the extension portion 64 appropriately. As a result, the engagement coupling portion 63 of the advance valve 60 adjusts its own elasticity to the end cone, forcibly passes through the penetration fitting hole 511 of the isolation plate 521, and at the same time, The penetration fitting portion 62 penetrates and fits in the penetration fitting hole 511 of the isolation plate 51, and exhibits a movable state. Subsequently, the extending portion 64 is cut.

The cover lid 50 is adhesively bonded at a large or middle diameter of the inner edge of the three-stage hollow circular cover 42 of the main body 40. Further, the extension portion 84 of the check valve 80 penetrates the penetration fitting hole 4311 and the circular tank 4313 of the main body 40 and stops the extension portion 84 appropriately. As a result, the engagement portion 83 of the check ring 80 adjusts its own elasticity to the end cone shape, forcibly passes through the through-fitting hole 4311 of the isolation plate 431, and is inserted into the tank 4311 of the isolation plate 431. Installed in At the same time, the penetration fitting portion 82 of the check ring 80 penetrates and fits in the penetration fitting hole 4311 of the isolation plate 431, and exhibits a movable state. Subsequently, the extending portion 84 is cut, and the cover pipe 91 of the pump 90 and the air pipe 422 of the main body 40 are connected to complete the combination.

As shown in FIGS. 20 and 21, at the time of use, the air charging device is brought into close contact with the outer peripheral surface of the air tube A, and is fixed using high frequency. Further, the pump 90 is pushed by a manual method, and the air in the pump 90 pushes the sealing thin film 61 of the inhalation valve 60 to close the inhalation hole 512 of the cover lid 50. On the other hand, the air-permeable hole 4212 of the isolation plate 421 pushes the sealing thin film 71 of the air supply valve 70, and the air flows into the air tube A to expand the air tube A.

At the same time, the air inside the air tube A pushes the check valve 80. As a result, the sealing thin film 81 of the check ring 80 closes the U-shaped aeration hole 4315 of the isolation plate 431. Further, as shown in FIG. 22, the pump 90 generates a negative pressure due to the restoring force of the material itself, and the sealing thin film 71 of the air supply valve 70 closes the air holes 4212 of the isolation plate 421, and Open 60. Thus, the air outside the air tube bag A flows from the air vent 512 of the isolation plate 51 through the three-stage hollow circular cover 42 of the main body 40 and the air pipe 422, and finally flows in until the pump 90 recovers its original state.

At this time, due to the air pressure inside the air tube A, the sealing thin films 71 and 81 of the air supply valve 70 and the backflow prevention valve 80 reliably seal the aeration holes 4212 and 4315 of the isolation plates 421 and 431. Further, as shown in FIG. 23, when the air in the air tube A is exhausted, the arc-shaped pressing piece 4314 of the main body 40 is pressed using a finger. As a result, the localization convex block 4312 forms an inclined shape in conjunction with the check ring 80, and the sealing thin film 81 of the check ring 80 is separated from the close contact of the isolation plate 431 with the U-shaped advance hole 4315. Thus, the air in the air tube A is smoothly discharged from the U-shaped advance hole 4315, and the size of the air tube A can be adjusted. If you want to accelerate the exhaust, press the air tube A accordingly.

Further, when performing the air charging operation by the mouth in the air tube, the air is directly blown into the cylindrical hollow circular cover 43 of the main body 40 by blowing the air (when the air is filled, the port is brought into contact with the main body 40). Whether or not to do so is selected as necessary (see FIG. 24). As a result, the air pushes open the sealing thin film 81 in the U-shaped aeration hole 4315 of the main body 40, enters the air tube A, and inflates the air tube A.
