Abstract
The utility model discloses a diving breathing apparatus which comprises a respirator and a conduit, wherein the respirator is provided with a one-way break valve connected with the exterior and a one-way break valve connected with the conduit; a floater is connected with the lower end at the exit of the conduit. The respirator is provided with a one-way break valve connected with the exterior and a one-way break valve connected with the conduit, making the expired-out gas discharged out of the respirator without entering the conduit, so only the air is absorbed in; a floater is connected with the lower end at the exit of the conduit and the floating force of the floater is utilized to make the conduit kept above the surface of the water all the time to be communicated with the air. The utility model has simple structure, no need of an oxygen supply device, direct air absorption, deep diving depth and safe use.
Description
Technical field the utility model relates to a kind of diving breathing apparatus, belongs to the diving outfit field.Background technology is present, and diving equipment generally is the diving equipment that has the oxygen feedway of specialty, its complex structure, and the cost height should not be popularized; And the device that simply snorkels just connects a conduit on the oral type respiratory tract, and the limited length of this conduit can not realize diving truly.
Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, provides a kind of simple in structure, not aerobic air feed system, and direct aspirated air, submerged depth is dark, and action radius is big, diving breathing apparatus safe in utilization.
The technical solution of the utility model is as follows: a kind of diving breathing apparatus, comprise respirator, conduit, on respirator, be provided with the unidirectional stop valve of outside single-pass and with the unidirectional stop valve of conduit single-pass; It is cursory that the lower end, exit of conduit is connected with.Respirator be provided with the unidirectional stop valve of outside single-pass and with the unidirectional stop valve of conduit single-pass, make outside the air scavenge respirator of exhalation, do not enter conduit, and air is sucked; It is cursory that the lower end, exit of conduit is connected with, and utilizes cursory buoyancy that conduit is on the water surface all the time, with the air conducting.
Described cursory be that air bag, hollow balloon or proportion are less than 1g/m
3Material cursory.
The exit of conduit and cursory between be provided with buoyancy sealing valve.When the degree of depth of dive surpassed the length of conduit, buoyancy sealing valve blanked-off pipe mouth under the buoyancy of water effect can not enter water, air also can not enter, and the diver feels to suffocate, and the degree of depth of knowing dive surpasses the length of conduit and reduces the degree of depth of dive, cursory rising, buoyancy sealing valve is opened.
Described buoyancy sealing valve is a lever sealing valve, and this sealing valve is in the lower end, exit of conduit bonded assembly L bracket, and its tail end flexibly connects lever, and the tail end of lever is connected with ball float, and the front end of lever is provided with pressing plate.Ball float contact water both rose, and made the exit sealing.
Described buoyancy sealing valve is the sliding type sealing valve that is connected the conduit outlet place, and there is a door on the top of this sealing valve, and the duct wall under it is provided with induction opening, and conduit is sliding combined with float valve, float valve by proportion less than 1g/m
3Making of material.Float valve contact water both rose, and made the induction opening sealing.
Described buoyancy sealing valve is a piston type sealing valve, this sealing valve is to be connected the downward exit of conduit, is provided with step in the middle of the piston bush of piston type sealing valve, and the lower end of piston bush is provided with the baffle ring piston and places under the step, piston is connected with the buoyancy plate by connecting rod, the buoyancy plate by proportion less than 1g/cm
3Making of material.Buoyancy plate contact water both rose, and made piston be in closed state.
Diving breathing apparatus conduit of the present utility model has a noose, can make respirator be fixed on head, is difficult for pitching.
Of the present utility model simple in structure, not aerobic air feed system, direct aspirated air, submerged depth is dark, and is safe in utilization.
