Abstract

The invention discloses a diving breathing device, which adopts the scheme that two air pipes are fixedly installed in the middle part of a main float; float chambers are arranged at two sides of the main float; float valves are movably arranged in the float chambers; one-way valves are respectively connected with the lower ends of the two air pipes; the two one-way valves are installed in opposite directions; the two one-way valves are connected with a tee joint; the tee joint is connected with a flexible pipe; the flexible pipe is connected with a respirator; the respirator comprises a nose cup around which a seal membrane is arranged; the seal membrane is connected with a fixed line; the cone tip of each float valve points to the pipe orifice of each air pipe; a plurality of through holes are arranged at the lower parts of the float chambers; the air pipe at the left side of the main float is an air suction pipe; the air pipe at the right side is an air expiration pipe; and the main float floats on the water. The diving breathing device overcomes the defect of high expense and inconvenient carrying when a high-pressure oxygen cylinder is used and potential safety hazard in swimming, and is suitable for wide swimming and diving fans to use.

Description

Diving breathing apparatus

Technical field

The present invention relates to a kind of diving breathing apparatus.

Background technology

At present, people's breathing is all through carrying and use high-pressure oxygen cylinder to realize during underwater swimming, and this mode not only expense is high and carry inconvenience.Moreover; Like the people who swims a lot of now, wherein the people of learn swim is quite a few, and these swimming fan lacks special-purpose breathing equipment; In the process of motion, all there is potential safety hazard to a certain degree; And present diving gear complex structure, use cost and operating costs are high, and common swimming and diving fan are hung back.

Summary of the invention

To above-mentioned situation, it is a kind of simple for structure that the present invention provides, and safe reliability is high, and cost is low, is fit to the diving breathing apparatus that vast swimming and diving fan use.

For realizing above-mentioned purpose, a kind of diving breathing apparatus comprises that main float middle part installs two tracheaes; Main float both sides are provided with float bowl, and float valve is placed in the float indoor activity, and the lower end of two tracheaes connects check valve respectively; The installation direction of two check valves is opposite; Two check valves connect threeway, the threeway connection hose, and flexible pipe connects respirator; Said respirator is provided with diaphragm seal around comprising nose cup, and diaphragm seal connects static line.

In order to realize result optimizing, improve, improve Combination property of the present invention, further step is:

The awl point of said float valve is over against the mouth of pipe of tracheae.

The bottom of said float bowl is provided with several through holes.

The tracheae in said main float left side is an aspirate tube, and the tracheae on right side is an exhaust tube.

Said main buoys float is on the water surface.

The present invention adopts main float middle part to install two tracheaes, and main float both sides are provided with float bowl, and float valve is placed in the float indoor activity; The lower end of two tracheaes connects check valve respectively, and the installation direction of two check valves is opposite, and two check valves connect threeway; The threeway connection hose, flexible pipe connects respirator, and respirator is provided with diaphragm seal around comprising nose cup; Diaphragm seal connects static line; The awl point of float valve is over against the mouth of pipe of tracheae, and the bottom of float bowl is provided with several through holes, and the tracheae in main float left side is an aspirate tube; The tracheae on right side is the scheme of exhaust tube master buoys float on the water surface, uses high-pressure oxygen cylinder expense high and defective of carrying and the potential safety hazard of swimming and existing when having overcome diving.

The present invention compares the beneficial effect that prior art produces:

1, simple and practical, cost is low, is fit to vast swimming and diving fan use.

2, the float valve that adopts is the SELF CL gas tube orifice when main float sinking, makes user's water of can not choking.

3, adopt two check valves oppositely to install, make expiration and air-breathing, make swimming and diving fan can be drawn onto fresh air all the time in order from two tracheal ventilation.

4, accuracy of manufacture is low, and is easily manufactured, good in economic efficiency.

The present invention is applicable to that vast swimming and diving fan use.

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain.

Description of drawings

Fig. 1 is a constructional drawing of the present invention.

Fig. 2 is the front view of respirator.

Fig. 3 is the left view of respirator.

Among the figure: 1, main float, 2, float bowl, 3, through hole, 4, tracheae, 5, float valve, 6, check valve, 7, threeway, 8, flexible pipe, 9, respirator, 10, nose cup, 11, diaphragm seal, 12, static line.

The specific embodiment

By accompanying drawing Fig. 1, Fig. 2, shown in Figure 3; A kind of diving breathing apparatus comprises that main float 1 middle part installs two tracheaes 4, and main float 1 both sides are provided with float bowl 2; The movable float valve 5 of placing in the float bowl 2, the awl point of float valve 5 is over against the mouth of pipe of tracheae 4, and the lower end of two tracheaes 4 connects check valve 6 respectively; The installation direction of two check valves 6 is opposite, and two check valves 6 connect threeway 7, threeway 7 connection hoses 8; Flexible pipe 8 connects respirator 9, and respirator 9 is provided with diaphragm seal 11 around comprising nose cup 10, and diaphragm seal 11 connects static line 12; The bottom of float bowl 2 is provided with several through holes 3; The tracheae 4 in main float 1 left side is an aspirate tube, and the tracheae 4 on right side is an exhaust tube.

During use, respirator 9 is worn on user's the nose, is fixed on the head with static line 12, or flexible pipe 8 is kept in the mouth, when user's swimming and diving, main float 1 swims on the water surface.When air-breathing, fresh air gets into from the admission port of main float 1 left side tracheae 4, and air-flow is opened the check valve 6 on the left side, closes the check valve 6 on the right simultaneously, and fresh air gets into human body through threeway 7 and flexible pipe 8; During expiration, waste gas is discharged from mouth or in the nostril, and the check valve 6 that air-flow is closed the left side through flexible pipe 8 and threeway 7 is opened the check valve 6 on the right simultaneously, and waste gas is discharged through the tracheae 4 on the right.When user's submerged depth exceeded hose length, the main float 1 that floats on the surface was pulled to the underwater, absorbed water for preventing the user; The awl point that is provided with two float valves 5 at admission port and air extractor duct is over against admission port and air extractor duct, and when main float 1 sank, water got into from a plurality of through holes of float bowl 2 bottoms; Float valve 5 floats, and the awl point inserts admission port and air extractor duct, closes admission port and air extractor duct; Remind user's come-up, main float 1 can emerge automatically, and the water in the float bowl 2 releases automatically; Float valve 5 descends, and admission port and air extractor duct are ventilated again, and the user can proceed swimming and diving.
