Embodiment 1

[0040] The decompression breathing device described in the following text and drawings is used to decompress high-pressure gas into a gas that the user can breathe normally, and can be used in equipment related to underwater breathing devices. figure 1 A schematic diagram of the explosive structure of the decompression breathing apparatus provided by the present invention, figure 2 For the top view of the decompression breathing apparatus provided by the present invention, image 3 for figure 2 A-A sectional view in, Figure 4 For the structural schematic diagram of the main valve body of the decompression breathing apparatus provided by the present invention, please refer to Figure 1-Figure 4 , the decompression breathing apparatus provided by the present invention comprises a main valve body 1, and a decompression valve 11 arranged on the main valve body 1, an inflation valve 12, a low pressure chamber 13, a breathing hole 24 and an exhaust hole 14, and the main valve b...

Embodiment 2

[0054] The present invention provides a portable diving respirator, including the decompression breathing device as described in Embodiment 1, and a high-pressure gas cylinder detachably connected to the decompression valve 11 breathing device. Generally, high-pressure gas storage aluminum cylinders can be used.

[0055] Specifically, a connector 21 is provided at the bottom of the main valve body 1, and two vent holes 14 are provided on both sides of the connector 21 respectively. An annular silicone gasket 22 is arranged outside the vent hole 14, and a high-pressure gas cylinder The connecting head 21 is screwed to the main valve body 1 and the silicone gasket 22 is fixed.

[0056] In the portable diving respirator provided by the invention, the user can breathe underwater by biting the breathing mouthpiece, and adopts a small high-pressure aluminum bottle for storing gas, which is not tied to the user and is easy to carry. The buoyancy effect offsets most of the gravity of...

Abstract

The present invention relates to an underwater breathing device, detailed description of the preferred embodiments relates to a decompression breathe apparatus and a portable diving respirator, A low-pressure breathe apparatus includes a main valve body, and a pressure relief valve arranged on the main valve body, Inflation valves, low pressure chambers, Breathing holes and vent holes, A main airpassage is arrange in that main valve body, decompression and inflation channels, The pressure-reducing and breathing device of the invention integrates each airway in the main valve body, and realizes the functions of inflating the gas cylinder and decompressing the gas through the main valve body. The device has the advantages of simple and smart structure, low cost, miniaturization and portability of the submersible respirator by cooperating with the small high-pressure gas storage cylinder, and is convenient for the user to sneak freely under water.

Description

【Technical field】 [0001] The invention relates to an underwater breathing device, in particular to a decompression breathing device and a portable diving respirator. 【Background technique】 [0002] Existing underwater breathing equipment mainly includes strap-type scuba, floating-type scuba, and mermaid bionic gill-type scuba. The strap-type scuba requires the user to carry a pre-compressed air bottle on the back Diving underwater, this kind of air bottle is heavy, and the user looks cumbersome underwater, and it is troublesome to carry; the air bottle of the floating scuba floats on the water surface, and the user bites the breathing hose for diving. This kind of underwater breathing apparatus is relatively light in weight, but the equipment is relatively restrictive, and it is difficult for the user to dive freely underwater; the oxygen preparation effect of the mermaid bionic gill type underwater breathing apparatus needs to be considered, and the structure is complex, in...
