Description

M273527 4. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is about a breathing tube structure, which can be used for snorkeling activities in shallow waters such as lakes and sea waters, or as equipment for diving training. [Prior art] In the natural state, breathing action refers to the cycle of using the nose or mouth to inhale gas to the lungs, and then exhaling exhaust gas from the nose or mouth. The difficulty of breathing has a significant relationship with the length of the path of the gas. The longer the path of the gas, the more difficult it is to breathe.

When snorkeling in shallow water, because the face is under the water, under the condition that the mouth and nose are lower than the water, you must use an appliance to perform breathing. The aforementioned assistive device is, for example, a breathing tube. Referring to the ninth figure, a general breathing tube 80 includes a long tubular body 82 and a mouthpiece 84 connected to one end of the body 82. Wherein, the tube body 82 and the mouthpiece 84 have hollow passages 822 and 8 4 2 communicating with each other. During snorkeling, the user bites the mouthpiece 8 4 with his mouth and exposes one end of the tube body 8 2 to the water surface. Although the user's face is under the water surface, he can still inhale through his mouth and The exhalation action causes the outside air to enter the human body through the channels 822 and 842 communicating with the mouthpiece 84 through the tube body 82. Conversely, the exhaust gas is also discharged to the outside through the passages 8 2 2, 8 4 2 communicating with the pipe body 82 and the mouthpiece 84.

With the above-mentioned breathing tube 80, the entry position of the gas is at the top of the coughing breathing tube 80, so for each breathing action, air must travel from the top of the tube body 8 or from the inside of the tube body 8 to the user's lungs. Compared with breathing in the natural state, the path of gas travel is longer, so use this breath

Page 6 M273527 Old and Creative Instructions (2) Suction tube 80 breathing will obviously increase the difficulty of breathing movements, and will also leave most of the exhaust gas emitted by the breathing movements inside the tube body 82. As the user continues to breathe, the amount of exhaust gas in the tube body 8 will continue to increase, and at the same time, the user will inhale the exhaust gas into the body every time he breathes. Repeatedly for a period of time, the user will feel difficulty breathing, dizziness, and evil. In addition, the user's necessary air will not be drained. It is more difficult to breathe, and the head may cause the exhalation tube that is easier to accumulate the exhaust gas. In line with the reality [new content of this creative structure, in the use of this creative structure, in the use of the upper axial air valve. The process water using the breathing tube 80 will flow into the tube body 8 2, and it is necessary to expel the water to expel the water out of the tube body 8 2, otherwise the outside will replenish the inside of the tube body 8 2. In a normal state, it is more difficult to exhale. If the user has experienced dizziness and nausea, the water will not be easily discharged, and the user will inhale the water and get water. The breathing tube described in the prior art has disadvantages such as poor ventilation effect, capacity, and difficulty in exhaling and draining water. Therefore, the invention provides a straw structure to solve the disadvantages of the prior art and meet the needs of breathing. One of the objectives is to provide a better breathing effect when using a breathing tube knot for diving. Another purpose is to provide a breathing tube knot for diving, which makes it easier to exhale and drain water. To describe the purpose and effect, this creation is to divide the ventilation pipe of the beer straw into two channels, and connect one end of the ventilation pipe with a ventilation valve with two one-way valve channels, and each valve channel is

苐 Page 7 M273527 4. Creation Instructions (3) One channel and one unidirectional valve channel, and the other channel and the other one-way channel, according to which the inspiratory and exhaling effects are achieved. A one-way water flow valve, and the air passage of the valve can be connected to each other in the passage that responds to the suction action. In this way, the combination can be used as a gas channel when inhaling. The combination of valve channels can be used as a gas channel when exhaling to achieve better ventilation. A door is only allowed in the axial direction of the ventilation valve. When water flows from the air inlet channel to the suction pipe, the water is automatically guided to the user's exhalation and drainage.

Please refer to the fourth picture, which reveals a ventilator 30. The ventilation valve

Page 9 M273527 Fourth, the creation instructions (5) 3 0 and the components described in the third picture have the same use effect. The structural difference is that a wide piece 6 9 2 is opened on the top surface of the expiratory wide channel 6 6 so that the expiratory valve channel 6 6 forms a one-way valve channel instead of the one shown in the third figure. The structure of the valve 6 7 is used. Please refer to the second figure again, the mouthpiece 40 is a component with a hollow interior and an opening 4 2 at one end. In use, the user attaches his mouth to the opening 42 position of the mouthpiece 40. Please refer to the fifth figure, after the ventilation tube 20, the ventilation valve 30, and the mouthpiece 40 are combined into a breathing tube 10, the intake channels 5 2, 5 6 and the suction channel that communicate with each other The air valve channels 62 are connected. The exhalation passages 5 4 and 5 8 are connected to the exhalation valve passage 6 6. Please refer to the sixth figure. When the user inhales through the mouthpiece 40, the inside of the mouthpiece 40 will form a negative pressure state, so that the valve plate 6 4 faces the mouthpiece 40. The internal direction is turned on. At this time, the valve 67 located in the exhalation valve passage 66 is closed. Therefore, the outside air, or the air remaining in the intake passages 5 2 and 5 6, can pass through the suction valve passage 62 of the ventilation valve 30 and enter the mouthpiece 4 0, and then the user's Mouth reaches the lungs. Please refer to the seventh figure. When the user exhales air from the mouthpiece 40, the suction valve channel 6 2 of the ventilation valve 30 will be caused by the inside of the mouthpiece 40. A positive pressure is generated and it automatically closes, thereby sealing the intake valve passage 62. In this way, the exhaust gas discharged by the user will enter the exhalation valve passage 64 and push the valve plate 69 of the valve 67. In this way, the exhaust gas enters the exhaust passages 5 8 and 5 4. It can be seen from the use state of the sixth and seventh figures that this creation can separate the channel for inhalation and the channel for exhaust during use, and the exhaust gas emitted
