Abstract

(57) [Summary] [Purpose] To provide a mouthpiece for an underwater breathing apparatus that has a simple structure, prevents water from entering beyond the mouth even when the mouth is moved, and allows safe diving. [Structure] Between the end of the short connecting tube 2 of the mouthpiece 1, which has the connecting short tube 2 and the mouth-fitting collar 4 equipped with biting protrusions 3, 3, and the mouth-fitting collar 4, A flange 6 for adsorption on the outside of the mouth is provided with a size that covers the outside of the lips 7.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is for breathing equipment used underwater by connecting to snorkels, regulators, etc. Regarding mouthpieces.

0002

[Conventional technology]

Conventionally, mouthpieces for underwater breathing devices have a connecting short tube, a flange that fits into the mouth, and a mouthpiece. It has a protrusion for insertion and an air hole, and is connected to a snorkel, regulator, etc. When wearing it, fit the tsuba that fits into your mouth between your lips and gums, and insert the biting protrusion into your teeth. The mouthpiece was fixed in the mouth by biting down.

0003

[Problem that the idea aims to solve]

However, with the above-mentioned one, the chewing protrusion is constantly chewed and the mouth is inserted into the mouth with the lips. If you do not wrap the guard, you may move your mouth when breathing, opening your ears, blowing on your mask, etc. However, water entered the mouth, and I had to blow out the mouthpiece frequently.

0004 Therefore, the present invention has a simple structure that prevents water from entering through the mouth even when the mouth is moved. Our aim is to provide a mouthpiece for underwater breathing apparatus that allows safe diving. It has been the target.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the mouthpiece for a breathing apparatus of the present invention has a connecting short tube, A mouse for underwater breathing apparatus having a collar for fitting into the mouth, a protrusion for biting, and an air hole. In the splice, a flange for adsorption outside the mouth is provided on the connecting short pipe side of the flange for fitting into the mouth. It is characterized by

[0006]

[Effect]

As a result, the external adsorption flange covers the area around the mouth and absorbs water pressure or air when inhaling. It adheres tightly to the mouth due to tensile stress and prevents water from entering from the mouth.

[0007]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0008] Mouthpiece 1 is made of synthetic resin and has an airtight connection to the regulator and snorkel at one end. The connecting short pipe 2 that is attached to the mouth is fitted into the mouth with projections 3 for biting on the other end. An air hole is formed from the connecting short pipe 2 to the flange 4 for fitting into the mouth. 5, and between the connecting short pipe 2 and the flange 4 for fitting into the mouth, there is a flange for adsorption outside the mouth. There are 6.

[0009] The flange 4 for fitting into the mouth is formed in a size that can be fitted between the lips 7 and the gums 8. , an air hole 5 is opened in the center, and two bite protrusions 3 are provided on both sides of the air hole 5. It is.

0010 The external mouth adsorption flange 6 is large enough to cover the outside of the lips 7, and has a portion that comes into contact with the lips 7. Folds 9 are provided as appropriate. The material is silicone rubber with a hardness of 30. An angle between 40° and 40° is optimal in terms of sealing performance and fit.

[0011] When using the mouthpiece 1 as described above, the flange 4 for fitting into the mouth should be connected to the lips 7. It is attached between the gums 8 and fixed by biting the biting protrusions 3, 3 with the teeth 10. On this occasion , the external mouth suction flange 6 is adsorbed around the outside of the lips 7, and when submerged underwater, it absorbs water pressure and air. It adheres tightly to the outer periphery of the lip 7 due to the tensile stress when it is worn. Also, the part that comes into contact with the lips 7 Since the pleats 9 are appropriately provided in each portion, the adhesion is further improved.

0012 This kind of mouthpiece 1 was actually used in a swimming pool at a depth of 5 m, and the ears were exposed when breathing. Even if you move your mouth when blowing or blowing your mask, there is almost no amount of water entering from your mouth. The sealing performance has been significantly improved, and the biting protrusions 3 and 3 do not have to be bitten all the time like before. Even without it, water did not get in from the mouth.

[0013] In addition, it is easy to wear, and the part that is held in the mouth has the same 4-piece collar for fitting into the mouth as before. Since there are protrusions 3 and 3 for biting, there is no discomfort, and on the contrary, the outside of the lips 7 is used for adsorption on the outside of the mouth. Since it is covered with the flange 6, there is a sense of security, and furthermore, the outside of the lips 7 is covered with the flange 6 for adsorption on the outside of the mouth. Since it is covered, it also looks great.

[0014] In this embodiment, the folds 9 are provided on the external mouth suction collar 6, but the folds 9 are not specially designed. Even if it is not provided, the adhesion force to the lips can be maintained sufficiently.

[0015]

[Effect of the idea]

As described above, the present invention provides a mouthpiece for underwater breathing apparatus with a flange for adsorption on the outside of the mouth. The structure is simple and makes it difficult for water to enter from the mouth even when you move your mouth. This improves the sealing performance of the mouthpiece, ensuring breathing underwater and safe diving. Be able to do it. In addition, the outside of the lips are covered with a flange for adhesion to the outside of the mouth. , the grotesque feeling when wearing the mouthpiece disappears.
