BACKGROUND OF THE INVENTION
The present invention relates to a protective mask capable of drinking water while being worn.
[0002]
[Prior art]
Conventionally, a first coupler socket, which is attached in an airtight manner through the face mouth and is connected to the elbow inside the mask, a stepped tube connected to the elbow, and an inner tube fitted to the stepped tube And a protective mask watering device which introduces water in the water bottle into the mask by connecting a second coupler socket provided on the stopper of the water bottle to the first coupler socket. It is disclosed in the gazette.
[0003]
In the above-described conventional drinking apparatus, it is possible to drink water by connecting the first coupler socket on the mask side and the second coupler socket on the water bottle side and then adding a drinking mouth formed at the tip of the inner tube.
[0004]
However, the mouthpiece of the inner tube is usually arranged so that it does not touch the face even if you move the mouth during conversation, etc. It must be brought close to the mouth, the operation is troublesome, and pressing the face mouth portion creates a gap between the mask face and the face, which may destroy the airtightness of the mask.
[0005]
Further, since the first coupler socket protrudes from the face opening portion, if the first coupler socket is brought into contact with or caught on any object, a part of the mask face body is separated from the face, which may adversely affect the airtightness.
[0006]
In addition, a through hole is formed on the side of the face opening portion of the protective mask so as to pass through the outside and inside of the mask, a coupler is fitted into the lower through hole, and a pipe is placed inside the mask of the coupler. The water drinking device body is attached, and the upper through-hole is biased outward by a spring, and a push button that can protrude inside and outside the mask is attached, and by pushing the push button inward from the mask outside, Japanese Patent Application Laid-Open No. 11-206897 discloses a protective mask that presses and bends the water drinking apparatus main body and brings the mouth piece at the tip thereof to the position of the wearer's mouth.
[0007]
According to this, by connecting a tube of a water bottle outside the mask of the coupler and pushing the push button to bring the mouth piece part closer to the wearer's mouth, it is possible to drink water without pushing the face mouth part and deforming it. it can.
[0008]
However, since this is a push button type, the number of parts increases, the structure becomes complicated, and the cost increases. Moreover, the fault that a coupler socket protrudes largely in the side of a face opening part is not improved.
[0009]
Further, since the water drinking apparatus body is bent by pressing the push button, it is difficult to adjust the pressing force, and in some cases, the mask face may be distorted and the airtightness may be lost.
[0010]

The protective mask of the present invention includes a mask face body and a water guide device that penetrates the face opening portion of the mask face body in an airtight state and is rotatable. The water guiding device includes a tube arranged inside the mask face piece and a coupler socket arranged outside the mask face piece. On the outer surface of the face mouth portion of the mask face piece, a concave portion for accommodating the coupler socket in a undulating manner is formed, and when the coupler socket is tilted, the inner end portion of the tube is separated from the center portion of the face mouth portion. The inner end of the tube is connected to the tube so that the inner end of the tube approaches the central portion of the face opening when it is moved away and stood up.
[0012]
During normal operation, the coupler socket is folded down and stored in the recess of the face mouth so that it does not get in the way and the inner end of the tube extends from the center of the face mouth, that is, Keep away from the wearer's mouth.
When drinking water, rotate the water guiding device by raising the coupler socket so that the inner end of the tube is close to the center of the face mouth so that the wearer can hold it, and a water bottle is attached to the outer end of the coupler socket. Connect.
[0013]
In order to bring the inner end of the tube closer to the wearer's mouth, it is only necessary to perform a turning operation, so there is no concern that the face mouth will be deformed by the pressing force.
It is possible to cover the outer surface of the coupler socket with a cap, to make the tip portion of the cap detachable from the coupler socket in the axial direction, and to project a knob portion on the outer surface of the tip portion of the cap.
[0014]
The structure covered with the cap prevents the coupler socket from being contaminated with toxic substances in the air, and the coupler socket can be easily erected by pulling the knob portion, and at the same time, the cap can be removed.
[0015]

As shown in FIG. 4, the water guide device B has an elbow joint 2 having a first pipe portion 13 inserted through the through hole 12 of the face port portion 8 and a second pipe portion 24 along the outer surface of the face port portion 8. A tube 3 arranged inside the mask face piece A, a coupler socket 1 attached to the second pipe portion 24 of the elbow joint 2 and placed outside the mask face piece A, and a face opening of the elbow joint 2 8 and an anti-contamination cap 4 that covers the outer surface of the coupler socket 1.
[0021]
On the inner surface of the face opening 8, an E ring 7 is attached to the outer periphery of the first pipe portion 13 of the elbow joint 2, and the water guide device B is fixed so as not to fall out of the face opening 8. In addition, an O-ring 6 is attached to the outer periphery of the first pipe portion 13 on the inner peripheral surface of the through hole 12 of the face opening portion 8 so that an airtight state can be maintained even if the water guide device B rotates. ing.
[0022]
Further, the inner end portion of the first pipe portion 13 of the elbow joint 2 is a stepped portion 14, and the outer end portion of the tube 3 is fitted on the stepped portion 14.
[0023]
The tube 3 is made of a relatively soft and flexible silicon rubber or the like. The tube 3 is bent at a substantially right angle with the rotating shaft 16 extending in the inner and outer directions of the mask face A and the inner end thereof. An arm portion 17 that is connected to the inner end of the rotating shaft portion 16 and whose axis is substantially parallel to the axis of the coupler socket 1 and the other end portion of the arm portion 17 are further bent at a substantially right angle so that the arm portion The mouthpiece 18 is connected to the other end of the mouth 17, and its axis is substantially parallel to the axis of the rotary shaft 16.
[0024]
Further, the inner diameter of the tube 3 is formed to be slightly smaller than the outer diameter of the stepped portion 14, and the tube 3 is fitted to the stepped portion 14 by tightly fitting the outer end portion of the rotating shaft portion 16. It is attached so as not to come out of the 1 pipe portion 13 and to rotate integrally. And when the tube 3 is attached in this way, the arm part 17 will be arrange | positioned substantially parallel to a wearer's face, and the drinking mouth 18 will extend toward a wearer's face mouth part.
[0025]
The coupler socket 1 is integrally connected to the end portion of the second pipe portion 24 of the elbow joint 2 through a seal washer 5 so as to extend in an airtight manner and substantially in parallel with the arm portion 17. In this way, the coupler socket 1 is connected to the tube 3.
[0026]
In addition, the size of the coupler socket 1 and the portion of the elbow joint 2 that are disposed outward from the face opening 8 is formed to be slightly smaller than the recess 20 formed in the face opening 8. 1 and the outer part of the elbow joint 2 are accommodated in the recess 20 of the face opening 8 so as to be raised and lowered.
[0027]
The cap 4 is made of elastic rubber or synthetic resin, and has a base covering portion 21 that covers the outer surface of the elbow joint 2 and a tip covering portion 22 that covers the outer surface of the distal end portion of the coupler socket 1.
[0028]
Further, as shown in FIG. 1, the opposing edges of the base cover portion 21 and the tip cover portion 22 are connected at a half-circular portion located on the inner side when the coupler socket 1 is tilted, and the half-circular portion located on the outer side is connected. In addition to being spaced apart, a knob portion 23 projects from the opposite edge of the tip covering portion 22.
[0029]
Therefore, when the knob portion 23 of the cap 4 is picked and pulled outward, the coupler socket 1 rises and the water guiding device B rotates. When the coupler socket 1 comes into contact with the upper wall of the recess 20 and does not rotate any more, if the knob portion 23 is further pulled outward, the base covering portion 21 is bent in an L shape and the movement is restricted. Only the tip covering portion 22 is removed, and the tip portion of the coupler socket 1 is exposed.
[0030]
When carrying out normal work while wearing the protective mask of the present invention, as shown in FIG. 1 and FIG. 8 is housed in a recess 20 formed on the outer surface of 8.

If it does in this way, the arm part 17 of the tube 3 will be arrange | positioned along the side wall inner surface of the surface mouth part 8, and the drinking mouth 18 will move away from the center part of the surface mouth part 8, and when a wearer talks, it will become an obstacle. Don't be.
When drinking water, if the knob portion 23 of the cap 4 is picked and pulled outward, as shown in FIG. 6, the coupler socket 1 rotates along the arrow a and protrudes to the side, and the water guiding device B It rotates counterclockwise in the figure with the center of the through hole 12 of the mouth 8 (the center axis of the rotation shaft 16 of the tube 3 and the first pipe portion 13) as the center of rotation.
As a result, the arm portion 17 of the tube 3 rotates along the arrow b, and the drinking mouth 18 provided at the tip of the tube 3 approaches the center portion of the surface mouth portion 8, that is, the wearer's mouth, and is gripped. become able to.
[0032]
Further, when the coupler socket 1 comes into contact with the upper wall of the recess 20 and no longer rotates, when the knob portion 23 is further pulled outward along the arrow c, the tip covering portion 22 of the cap 4 is detached and the coupler socket The tip of 1 is exposed.
[0033]
When a plug (not shown) attached to the tip of a water supply tube extending from the water bottle is connected to the exposed tip of the coupler socket 1, water in the water bottle can be drunk by sucking the mouthpiece 18 that has been added. .
[0034]
After drinking the water, the plug of the water bottle is removed, and the tip cover portion 22 of the cap 4 is put on the tip portion of the coupler socket 1, the coupler socket 1 is tilted and stored in the recess 20, and the mouthpiece 18 is attached to the wearer. Keep away from your mouth.
[0035]
In addition, the shape of the tube is not particularly limited to that of the above-described embodiment as long as the mouthpiece formed on the inner end portion is brought into contact with and separated from the wearer's mouth by raising and lowering the coupler socket. The shape of the tube 3 is excellent because only the mouthpiece 18 is close to the wearer's mouth and the other part is difficult to contact the face.
[0036]
【The invention's effect】
According to the first aspect of the present invention, since it is possible to drink water by a simple operation of raising the coupler socket and connecting the water bottle to the coupler socket, there is no need to push the mask face body inward. When the is operated, there is no concern that the mask face body is deformed by the pressing force and the airtightness is lost.
[0037]
Also, during normal work, the coupler socket located outside the mask face piece can be tilted and stored in the recess, so that the object can be caught in the protruding coupler socket and the mask face piece will not be deformed or detached, which is highly safe. .
Furthermore, even if a large load is unexpectedly applied to the coupler socket by accidentally dropping the water bottle while drinking water, the water guide device rotates to release the stress, and the collapsed coupler socket is supported by the peripheral wall of the recess. Therefore, safety is further improved.
[0038]
In addition, since a special device such as a push button is not required to bring the inner end of the tube closer to the wearer's mouth, the structure is simple, and an increase in cost can be suppressed.
[0039]
According to the invention of claim 2, the coupler socket can be prevented from being contaminated with toxic substances in the air, and the coupler socket can be easily erected only by pulling the knob portion, and at the same time, the cap is removed. Is possible.
[0040]
According to the third aspect of the present invention, by erecting the coupler socket, the arm portion rotates substantially parallel to the wearer's face, and the drinking mouth extending from the tip toward the face is securely attached to the wearer's mouth. Since the tube has no part that approaches the face when the coupler socket is tilted, it does not get in the way.
