Abstract

The utility model discloses an aqualung breathing apparatus for underwater swimming. Double-pipe control does not affect oxygen content when the air is sucked by a user. An air inlet has the function that the air inlet can be automatically closed under emergency condition, so the aqualung breathing apparatus for underwater swimming is safe, reliable and can not cause water-chocking phenomenon, is particularly suitable for safe protection for a swimming beginner and a swimmer who knows swimming lesson, and can be applied to waterborne life saving at the same time. The utility model is composed of a scavenging valve, a seal valve, a float and double guide air pipes. The utility model is characterized in that the scavenging valve is respectively connected with the two air-guiding pipes by two back-stop combination valves, the back-stop directions of which are opposite. The scavenging valve is connected with the sealed air admission valve on the float. One sealed float has a sealing plug 2 which is arranged at the lower side of the air inlet of the sealed ingress sucking valve and is just corresponding to the air inlet.

Description

Diving breathing apparatus

The utility model belongs to the device in respiration, and a kind of specifically mouth of using is in respiration, and don't the safety of the water of being choked is breathed apparatus.

At present, the kind of submersible is a lot of in the world, and very advanced on performance, successful Application is at deepwater work.And more easy submersible is to adopt single tube, one end keeps in the mouth, the other end surfaces, because individual tubes is used for simultaneously exhaling and is air-breathing, that breathes out is trapped in carbon dioxide in the pipe, influences the oxygen content when air-breathing, cause breathe more and more difficult, and diving depth is limited, poor practicability in the use.

The utility model purpose is to disclose a kind of diving breathing apparatus; it is simple in structure, dependable performance, cheap; Double tube; do not influence oxygen content when air-breathing; admission port has emergent automatic closing function, can not cause the water of choking, and is safe and reliable; be specially adapted to the beginning swimmer and swim underwater people's safety guard-safeguard of the study that has been able to swim, can be applicable to surface lifesaving simultaneously.

The utility model is by scavenge valve, seal valve, cursory and two ventilation flues form, it is characterized in that scavenge valve 7 has a breathing mouth 16 that can keep in the mouth, connect two ventilation flues respectively by two opposite check combine valves of check direction, link to each other with the seal valve on cursory, described seal valve seat drops on cursory 4, it has two ventilation flues that port direction is downward, join with two ventilation flues respectively, a sealing cursory 3 is below the vent of seal valve type 1, make by light material, go here and there up and down along conduit, a sealing plug 2 is respectively being arranged over against the air inlet/outlet place.

It is that described scavenge valve mainly is divided into discharge chamber 9, inlet chamber 14, respiratory cavity 15 by Y type dividing plate with valve body that the utility model more improves embodiment, respiratory cavity 15 joins with breathing mouth 16, on the dividing plate of respiratory cavity 15 and discharge chamber 9, a blow off valve film 10 is arranged, dividing plate at respiratory cavity 15 and inlet chamber 14 has an air inlet valve film 13, and a horn-like deflecting plate 17 is arranged in respiratory cavity 15.

It below is the utility model embodiment accompanying drawing.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model birds-eye view.

Fig. 3 is the utility model scavenge valve cutaway view.

Fig. 4 is sealed into the air valve cutaway view for the utility model.

Fig. 5 is the utility model running condition figure.

Among the figure 1 be sealed valve body, 2 for sealing plug, 3 cursory, 4 cursory for the water surface for sealing, 5 for intake guide, 6 for exhaust guide, 7 for scavenge valve, 8 for nasal obstruction, 9 for discharge chamber, 10 for the blow off valve film, 11 for deflation hole, 12 for induction opening, 13 for the air inlet valve film, 14 for inlet chamber, 15 for respiratory cavity, 16 breathe mouths, 17 for deflecting plate, 18 for induction opening, 19 for deflation hole, 20 for guide rod, 21 for breathing nasal obstruction.

The utility model is provided with breathing nasal obstruction 21 for being bad at the mouth breather, containing scavenge valve with mouth, breathe through two ventilation flues,, enter in the water in case be difficult for the water inlet water surface cursory 4 because port is downward, then seal cursory 3 come-ups, then the sealed plug 2 of port blocks, and port can not cause the water of choking, and the air-breathing check combine valve that passes through of exhaling is through intake guide 5, exhaust guide 6 ventilation, Double tube do not influence oxygen content when air-breathing.
