Leakage prevention device when the liquid feeding port falls

BRIEF DESCRIPTION OF THE DRAWINGS The principal part sectional drawing in the case of implementing this invention on an airport.

2 and 3 are cross-sectional views of intermediate plugs used in the leakage preventing device of the present invention, respectively.

The present invention is conducted in a liquid-type port such as an air port which causes the liquid in the bottle to flow out by a motor driving pump, or an air port which causes the liquid in the bottle to flow out by a so-called light pump or a manual air pump. It is about leak prevention device in case of).

In such a liquid feeding port, since the inside and the outside of the bottle are in communication with each other by a tube, when the pot is accidentally inverted, the liquid in the bottle easily flows out, soaking the floor or calories. Accidents such as burns occur.

Conventionally, there are some examples in which the stopper is equipped with a movable valve such as a ball valve to prevent leakage during port conduction, called an automatic stopper. However, in the conventional automatic stopper, the port may be in a normal position. Even at this time, the actuating valve was to close the water passage in the plug, so that a liquid leak-proof port that would have to be opened at the normal position of the port could not adopt a leak-proof structure in a conventional automatic stopper. .

For this reason, it has not been found that currently available electric ports or airports are equipped with an effective leakage preventing device that can prevent leakage when the port is turned over.

An object of the present invention is to provide a leakage preventing device effectively preventing an outflow of a liquid solution even when conduction is conducted in an electric port or an air port.

Referring to the present invention by the drawings, the air port 1 shown in FIG. 1 is equipped with an air pump 14 in the upper lid 17 connected by the pin 4 with respect to the lower member 5, by pressing the lid 15 Although the pressing operation is carried out, these members are not directly related to the gist of the present invention, and thus, detailed descriptions of the structure and the effect are omitted, and only the following scheme will be described.

When the air pump 14 is pressed, the pressurized air is blown into the inner bottle 2 after passing through the outlet 26 and the middle magnificent hollow 11, and the bottled liquid 16 pressed by the liquid surface by the pressurized air is supplied from the inlet 10 to the feed tube 8. It flows through the outlet pipe 12 (figure 2) and flows out of the bottle.

In the figure, reference numeral 9 denotes a 0 ring for maintaining airtightness between the intermediate plug 7 and the stopper hole 13, 21 is an intake valve for opening and closing the inlet 20 of the air pump, and 27 is a safety to prevent an incorrect operation of the push lid 15. It is a cover and the open state is indicated by the reference sign 27 '. Reference numeral 32 denotes a flange for positioning the intermediate plug 7 at a constant depth within the plug hole 13.

The internal structure of the intermediate plug 6 in the airport of FIG. 1 is demonstrated.

Referring to FIG. 2, the inside of the intermediate plug 7 is divided into the intermediate plug hollow 11 and the water passage 29, which serve as pressurized air passages. The liquid feed pipe 8 is attached to the lower stage opening of the channel 29, and the connection cap 33 of the outlet pipe 12 is fitted through the packing 30 with a hole in the upper opening. The liquid feeding pipe 8, the plug four channel 29, the hole 35 of the packing 30, and the outflow pipe 12 form a continuous liquid path and guide the liquid in the inner bottle to the outside.

In place of the stopper channel 29, a valve holder 36 for accommodating the ball-type movable valve 31 is formed. The movable valve 31 is accommodated in the valve holder 36 when the port is in the normal position. However, when the port is inverted, the packing hole 35 is closed as indicated by the symbol 31 'so that the liquid in the inner bottle flows in the direction of the outlet pipe 12. Outflow is prevented. When the conducted port is returned to the normal position, the movable valve 31 is naturally returned to the valve holder 36 by gravity.

FIG. 3 shows another embodiment of the valve holder, and unlike the method of forming the valve holder 36 on the shelf in the intermediate plug channel 29 as in the embodiment of FIG. Valve holder 76). Also in the embodiment of Fig. 3, when the port is in the normal position, since the ball-shaped movable valve is accommodated in the valve holder 76, the liquid in the bottle flows freely in the direction of the outlet pipe 52 during the pump operation. As in the case of Fig. 2, the movable valve 71 closes the packing hole 75, as indicated by the symbol 71 'by the action of gravity, so that the outflow of the liquid in the inner bottle is supported.

As is clear from the above, the leak prevention device of the present invention can simply and effectively prevent leakage when the liquid feeding port is turned over by the gravity action of the movable valve accommodated in the intermediate plug channel. It is rich in practical value that can prevent accidents such as burns at the time of port conduction, which has been a problem in the liquid feeding port up to this point. In addition, according to the present invention, when the movable valve port is in a normal position, it is in a position which does not inhibit the flow of water flowing in the intermediate plug channel, and is held in the valve holder, so that the liquid feeding action by the pump is extremely The effect is made smoothly.

Claims (1)

In a normal feed port, the pump 14 mounted inside the port allows the liquid 16 in the bottle 2 to flow out of the bottle through the feed tube 8, the intermediate conduit 29 and the outlet 12; The valve holder 36 is formed in the furnace 29. When the port is in the normal position, the valve holder 36 does not block the liquid flowing through the inner channel 29 in the intermediate holder. A device for preventing leakage during port conduction characterized in that the valve 31 moves from the valve holder 36 to close the inlet of the outlet pipe 12.
