One side of the valve core tube 2 is provided with an air inlet for oxygen to enter the valve core tube 2 from the one-way air inlet channel 102, and the other side of the valve core tube 2 is provided with an air outlet for exhaled air to be discharged from the one-way air outlet channel 103, so that oxygen can pass through the air inlet from the one-way air inlet channel 102 into the valve core tube 2 for inhalation by the user biting the mouthpiece 7, and the turbid air exhaled by the user can be discharged from the air outlet and the one-way air outlet channel 103.
[0024] A valve core tube drainage hole 202 is provided on one side of the valve core tube 2 between the air inlet and the handle portion 201 or on the other side of the valve core tube 2 between the air outlet and the handle portion 201, and a valve body drainage hole 104 is provided on the valve body 1. The central axis of the valve body drainage hole 104 and the central axis of the valve core tube drainage hole 202 are staggered and arranged on the same horizontal plane, so that under normal circumstances, when the valve body is used for breathing, no water will enter. When the central axis of the valve core tube drainage hole 202 coincides with the central axis of the valve body drainage hole 104 as the valve core tube 2 rotates, the one-way air inlet channel 102 and the one-way air outlet channel 103 are completely blocked by the outer wall of the valve core tube 2, so that the user who bites the mouthpiece 7 can blow air into the valve core tube 2, and then use the air pressure to discharge the water in the valve core tube 2 along the valve core tube drainage hole 202 and the valve body drainage hole 104.
[0025] Before use, the utility model can first make the valve core tube drainage hole 202 and the valve body drainage hole 104 correspondingly connected. The user bites the mouthpiece 7 and blows air into the valve body 1 first, so that the water in the valve body 1 is discharged along the valve core tube drainage hole 202 and the valve body drainage hole 104. Then, the handle 201 is immediately manipulated to rotate the valve core tube 2, so that the valve core tube drainage hole 202 and the valve body drainage hole 104 are misaligned to prevent water from entering. At this time, the air inlet is connected with the one-way air inlet channel 102, and the air outlet is connected with the one-way air outlet channel 103. When inhaling, due to the decrease in air pressure in the valve core tube 2, gas can enter the valve core tube 2 through the one-way air outlet channel 103 and the air outlet to meet the oxygen demand under water, and the turbid air exhaled by the user can be discharged along the air outlet and the one-way air outlet channel 103, so as to ensure normal oxygen supply while ensuring safety.
[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that the one-way air inlet channel 102 and the one-way air outlet channel 103 are coaxially arranged, and the common center axis of the one-way air inlet channel 102 and the one-way air outlet channel 103 is the first center axis; the air inlet and the air outlet are coaxially arranged, and the common center axis of the air inlet and the air outlet is the second center axis; when the center axis of the valve body drain hole 104 coincides with the center axis of the valve core tube drain hole 202, the first center axis and the second center axis are perpendicular to each other. Such a structural layout is simpler, while ensuring the size of the air inlet and air outlet of the one-way air inlet channel 102 and the one-way air outlet channel 103 as much as possible, it also ensures the sealing performance in the event of misalignment.
[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that a one-way water outlet valve 3 is installed in the valve core tube 2, and the one-way water outlet valve 3 is located below the drain hole 202 of the valve core tube, and the one-way water outlet valve 3 is located above the air inlet and the air outlet, and a one-way water membrane is installed on the one-way water outlet valve 3 to prevent water from flowing from above the one-way water outlet valve 3 to below the one-way water outlet valve 3 (not shown in the figure, and this design structure belongs to the prior art, therefore, no drawings are given and no further explanation is given), which can prevent water from entering the user's mouth and ensure the safety factor.
[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that a one-way air intake valve 4 is installed in the one-way air intake channel 102, and a gas one-way membrane is installed on the one-way air intake valve 4 to prevent gas from flowing from the valve body 1 through the one-way air intake channel 102 to the outside of the valve body 1, thereby preventing turbid air from flowing toward the oxygen tank when the user exhales turbid air.
[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that a one-way air outlet valve 5 is installed in the one-way air outlet channel 103, and a gas one-way membrane is installed on the one-way air outlet valve 5 to prevent gas from flowing into the valve body 1 from the outside of the valve body 1 through the one-way air outlet channel 103. This can ensure that when the user exhales turbid air, the airflow can be discharged stably, and the accumulation of turbid air in the valve core tube 2 can be avoided.
[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that a limiting ring 6 is installed at the upper end of the valve body 1 for pressing the valve core tube 2 into the valve body 1. The limiting ring 6 is connected to the valve body 1 by bolts. The valve core tube 2 is pressed by the limiting ring 6, which can ensure the stability of the valve core tube 2 and also realize loading and unloading to improve flexibility. The middle part of the limiting ring 6 is provided with an avoidance hole for facilitating the extension of the handle portion 201 to the outside of the valve body 1, without affecting the rotation of the valve core tube 2 by the handle portion 201.
[0031] As a preferred implementation scheme in this embodiment, it needs to be further explained that the avoidance hole is an arc-shaped hole. When the handle portion 201 is rotated to one end of the arc-shaped hole, the air inlet is corresponding to the one-way air inlet channel 102; when the handle portion 201 is rotated to the other end of the arc-shaped hole, the valve core tube drainage hole 202 is corresponding to the valve body drainage hole 104, so that the valve core tube 2 can be quickly and accurately adjusted into place whether it is drainage or breathing.
