First, looking at the overall configuration of the gas mask intake 10 in accordance with the present embodiment through FIGS. 1 and 2, the intake cylinder 1 is formed through the inlet hole for the inflow of beverage is the female screw portion on the lower inner peripheral surface (1a) and the engaging groove (1b) is formed on the upper outer peripheral surface of the O-ring groove (1c) and the fastening jaw (1d) is formed protruding, the inlet fixing pipe (2) that is sequentially fitted to the outside of the intake cylinder (1) ) And the inlet fixing ring 3 are formed with a locking groove 2a corresponding to the fastening jaw 1d and a locking groove 3a corresponding to the assembling protrusion 2b, respectively, for fastening. It can be stably fixed to the gas mask.

And, one side of the intake cylinder (1) is coupled to the intake straw (4) of the soft silicone rubber or synthetic rubber is to extend the inflow path of the beverage to one side inside the gas mask, the middle of the body to facilitate the intake The bent portion is bent and the intake end 5 of the intake straw 4 is inserted into the intake valve 5 for controlling the one-way flow of the fluid.

At this time, the intake valve (5) is provided with a separation prevention portion (5a) having a plurality of through-holes at one end, and is composed of a circular valve portion (5b) at the other end. The release preventing portion 5a is coupled to the seating portion 4a in the intake straw 4 to form a disc shape to prevent the separation, but a plurality of through holes are formed to secure the flow path, and the valve portion 5b is The flow path is completely closed by the line contact is made with the catching jaw (4b) protruding in the outflow end of the intake straw (4).

In addition, a screw stopper 7 is fastened to the intake cylinder 1 by a stopper band 6, and the screw stopper 7 is screwed with a female screw portion 1a of the intake cylinder 1. A portion 7a, a locking jaw 7b protrudingly provided such that an interference coupling is made to the locking groove 1b, and an o-ring groove 7c are formed.

In addition, the screw nipple (8) which is connected through the water bottle (not shown) and the connecting pipe (9) to guide the beverage also has the same configuration as the screw stopper (7), the male screw portion (8a) and the locking jaw (8b), And the o-ring groove 8c is provided.

In particular, the female screw portion (1a) and the male screw portion (7a, 8a) is provided in the form of four rows of trapezoidal screw screw screw 7 or screw nipple (8) by the rotation of the minimum angle (90 degrees) It is preferable to be able to be fastened to the water intake cylinder (1).

On the other hand, in the present invention, the position of the intake port 10 is located in the lower center of the gas mask as shown in Figure 3, on both sides of the gas mask surface purifying tank coupling portion 20 so as to selectively determine the mounting position of the purification container, respectively By providing it, it was possible to change the position of the purification container to the left and right side easily.

In the drawings, reference numerals 11 and 12 denote O-rings fitted into the corresponding O-ring grooves 1c, 7c, and 8c to maintain the airtightness of the flow path, and 21 denotes the electrical plate.

Hereinafter, the effect of using the water intake port of the present invention constituting the above configuration will be described.

The intake port 10 of the present invention is normally stored in the gas mask in a state in which the intake straw 4 is turned toward the side as shown in FIG. 3 so as not to interfere with the lips when talking or wearing the gas mask. This is to prevent inconvenience, in this case, the screw cap 7 of the four-line trapezoidal shape is coupled to the lower portion of the intake cylinder (1) to close the external connection flow path.

5 shows a step in which the screw cap 7 is coupled, and when the screw cap 7 is rotated in one direction, the male screw portion 7a is screwed with the female screw portion 1a of the intake cylinder 1. When the initial insertion is made while the screw stopper 7 is continuously rotated by 90 degrees, the locking jaw 7b portion is pressed together with the sound of "clicking" on the locking groove 1b of the intake cylinder 1. As the fitting is made, the fastening is made while maintaining the airtight state of the flow path.

Therefore, even if the user does not directly check the coupling state with his own eyes, the user can recognize that the closing of the flow path is completely made through the fastening sound.

On the other hand, when the gas mask wearer wants to take a drink through the intake port 10, as shown in Figure 6 by rotating the screw cap 7 in the opposite direction to remove the screw cap 7 from the intake cylinder (1) The screw nipple 8, to which the connecting pipe 9 is connected, is then quickly coupled to the intake cylinder 1 inlet side. At this time, the coupling process is to be made in the same manner as the coupling operation of the screw cap (7) to omit a detailed description, accordingly the screw nipple (8) can achieve a stable coupling state.

Thereafter, when the intake port 10 is rotated 90 degrees to the face side, the intake straw 4 is opposed to the wearer's mouth as shown in FIG.

At this time, since the valve portion 5b of the intake valve 5 keeps the outlet of the intake straw 4 completely sealed, it is harmful from the outside in the process of replacing the screw nipple 8 or the screw cap 7. The gas can be completely prevented from entering.

In such a state, when the wearer of the gas mask bites the outlet end of the intake straw 4 by the mouth and presses the portion indicated by the arrow in FIG. 6 with the teeth or the lips up and down, the intake straw is shown in FIG. 7. As the outlet of 4) opens to both sides, a predetermined gap d is formed at both sides of the intake valve 5.

Thus, as the outflow end is opened and the intake passage is secured, the drawing wearer can easily intake the drink by sucking the water intake straw 4 by sucking the water or drink contained in the water bottle.

When the water intake of the desired amount is completed, the intake flow passage is again closed by the intake valve 5 by releasing the compressive force on the outlet end of the intake straw 4, and then the screw nipple 8 and the screw Replace the stopper 7 again to achieve the original state.

On the other hand, the intake assembly of the present invention is separated for each part as shown. Since the coupling structure is easy to be combined, the user can separate the intake straw (4), the intake fixing tube (2) and the intake cylinder (1) after each use by using the intake device, and then clean and store the intake fixing tube (2). When the intake cylinder (1) fixed to the rotation is applied 180 degrees counterclockwise to apply a force to each other to enable separation and storage and management can be made clean.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the intake coupling structure of the present invention may be variously modified and implemented by those skilled in the art.

Therefore, such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

As described above, the intake coupling structure of the present invention is a screw system in which the coupling is made in a small angle (90 degrees) in the gas mask when the wearer combines the nipple of the connector to the intake to take water or other beverage contained in the water bottle By providing a fastening structure in which an over-fitting coupling method is performed in parallel, it is possible to confirm a stable coupling without being skewed, thereby preventing the harmful gas inflow due to external leakage of the coupling portion.

In addition, since the intake port is located in the lower center of the gas mask, it is possible to selectively combine the purifying container on either the left or the right side of the gas mask, thereby improving the compatibility of the product according to the physical characteristics of the user.

In addition, since each component is separated from each other after the use of the intake to form a prefabricated structure that can be cleaned, it shows the advantage that the product can be managed and stored.
