2. Description of the Related Art As a conventional breathing apparatus of this type, there are, for example, a scuba diving (diving) regulator device, a medical or life-saving oxygen mask device, a gas mask and the like.

[0003]

The above-mentioned conventional breathing apparatus has a problem that drinking water cannot be drunk when the breathing apparatus is worn on the human body.
For example, in scuba diving, it is dangerous and almost impossible to remove the mouthpiece of the regulator from the mouth and drink drinking water underwater. On the other hand, the compressed air contained in the breathing air tank used for scuba diving is dry,
When using it for underwater work, it is easy to get thirsty,
It is desired to make drinking water available in the water.

Similarly, in a medical or life-saving breathing apparatus, it is desirable that the user can drink the beverage while wearing it. The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to provide a breathing apparatus including a beverage supply means that allows a beverage to be drunk while being worn on a human body.

[0005]

In order to solve the above-mentioned problems, the present invention provides a breathing apparatus for supplying breathing gas to an air supply port of a mouthpiece, wherein a tip portion is provided at a part of the mouthpiece. Penetrating from the inside of the mouthpiece to the base end of the liquid injection pipe facing the air supply port, and connecting the base end of the liquid injection pipe to a beverage container via a valve arranged outside the mouthpiece. It is characterized by having done. Instead of the mouthpiece, a mask to which breathing gas is supplied, a mask including an intake purification means, or the like may be used.

[0006]

[Function] By applying the mouthpiece or mask to the mouth and opening the valve with the injection pipe held in the mouth,
With the breathing apparatus attached to the human body, the beverage in the beverage container can be drunk.
