Abstract

The utility model relates to a breathing device used for underwater air exchange, which belongs to the auxiliary tool in swim or dive. The utility model is mainly composed of an air chamber, an air guiding pipe and an air exchange opening. The both ends of the air guiding pipe are respectively connected with the air chamber and the air exchange opening. The connecting part is fixed and sealed. The air chamber is provided with an air hole communicated with the atmosphere. The utility model has simple structure, good water choking prevention, collapsible property and easy portability.

Description

Rebreather

The utility model is a kind of respirator of the usefulness that is used for taking a breath under water, the accessory appliances when belonging to swimming or diving.

Interim when summer of sweltering heat, people's swimming of being everlasting in beach or the swimming pool is played, and relieving summer-heat is enjoyed the cool, even in other season, and swimming a kind of mode of motion of taking exercises preferably of also can yet be regarded as.But in the swimming process,,, then hope " water " to give birth to fear especially especially for the people of first learning swim usually because of the improper water of choking that causes of respiration air exchanging method.

The purpose of this utility model is a kind of rebreather of design, and it is simple in structure, can solve the problem of swimmer's underwater breathing, prevents the water of choking.

The designed rebreather of the utility model mainly is made of air chamber, ventilation flue and scavenge port, and ventilation flue's two ends are connected with air chamber and scavenge port respectively, and the junction sealing and fixing has the pore that communicates with atmosphere on the air chamber.

The air chamber of the rebreather that the utility model is designed is made of ring seal chamber and air-exchanging chamber, and air-exchanging chamber is positioned at the centre of ring seal chamber, and the ventilation flue is communicated with air-exchanging chamber, and the upper surface of air-exchanging chamber has the pore that communicates with atmosphere.

For anti-sealing enters in the air-exchanging chamber, on the pore of the air-exchanging chamber of the designed rebreather of the utility model, have drainage layer or water deflector cover.

The port of the scavenge port of the rebreather that the utility model is designed is a circular arc, conveniently to be positioned in the mouth.

The air chamber of the rebreather that the utility model is designed, ventilation flue and scavenge port are made by non-poisonous soft material, have valve in the ring seal chamber of air chamber, can fill, exit, so that folding.

The designed rebreather of the utility model when using, earlier with the indoor inflation of the ring seal of air chamber, treat the inflation of ring seal chamber after, valve is covered.With filling fraction water in the air-exchanging chamber of air chamber, be used to prevent the air chamber overturning then, the swimmer blocks nasal cavity, in the port insertion mouth with scavenge port, can pull the plug.The swimmer is when swimming, because on air chamber is bubbled through the water column all the time, therefore people can breathe by mouth under water, end and ventilation flue from scavenge port discharges with the gas in the body, gas in the air-exchanging chamber is by the pore and the atmosphere exchange on top, fresh air in the air-exchanging chamber enters in swimmer's the body by the other end of ventilation flue and scavenge port again, reaches the purpose of underwater breathing, ventilation.

The advantage of the rebreather that the utility model is designed is:

1. simple in structure, easy to use.Owing to itself make, therefore be easy in use move, and need not emerge and to take a breath applying flexible with the swimmer by soft material.

2. prevent the water of choking preferably, very be suitable for the people of learning swim just.Just the people of learning swim can be by the rebreather study of taking a breath, elimination fear, high safety.

3. collapsible, be easy to carry about with one.

The designed rebreather of the utility model mainly is applicable to swimmer's learning swim, diving etc., is the accessory appliances of swimming instruction.

Fig. 1 is the constructional drawing of the designed rebreather of the utility model.

Fig. 2 is the structural representation of air chamber among Fig. 1.

In conjunction with specific embodiments the structure and the embodiment of the designed rebreather of the utility model is described further with reference to the accompanying drawings below.

Embodiment

Rebreather as shown in Figure 1, mainly by air chamber 1, ventilation flue 2 and scavenge port 3 constitute, air chamber 1 as shown in Figure 2, form by ring seal chamber 4 and air-exchanging chamber 5, ring seal chamber 4 is isolated with air-exchanging chamber 5, have valve 6 on the ring seal chamber 4, air-exchanging chamber 5 is positioned at the centre of ring seal chamber 4, the top of air-exchanging chamber 5 has pore 7, is threaded 10 on the pore 7, and the axis direction of screw thread 10 has the air drain 11 to central concave, water deflector cover 8 cooperates with screw thread 10, the upper end of water deflector cover 8 inside top surface and screw thread 10 has the gap, and air can enter by the gap of air drain 11 and upper end in the air-exchanging chamber 5, enters in the air-exchanging chamber 5 to prevent water.An end of ventilation flue 2 and the lower seal of air-exchanging chamber 5 are fixedly installed togather, and the other end and scavenge port 3 sealing and fixing are installed together, and air-exchanging chamber 5 is connected with scavenge port 3.Ventilation flue 2 is non-poisonous plastic whorl flexible pipe.Scavenge port 3 is commercially available scavenge port, is made by soft non-toxic material, is similar to the triple valve shape, is made of port 9, coupling end 12 and ventilation end 13, and port 9 places are circular arc, and are similar to the shape of mouth, are easy to put into mouth, and convenient carrying in water moved about; Coupling end 12 is tightly connected with an end of ventilation flue 2; Ventilation end 13 places have the patch 14 of unidirectional conducting; During exhaust, a part of gas is pushed patch 14 open and is entered in the water, and when air-breathing, patch 14 will be taken a breath and be held 13 places to block, and anti-sealing enters in the scavenge port 3.

When using, the swimmer with inflation in the ring seal chamber 4, after the inflation blocks valve 6 earlier, will put into a spot of water in the air-exchanging chamber 5 then, and the swimmer blocks nasal cavity, and port 9 is placed mouth, can pull the plug.Air chamber 1 floats on the water surface, and owing to have low amounts of water in the air-exchanging chamber 5, therefore is difficult for upset.The swimmer sucks fresh air by ventilation flue 2 in air-exchanging chamber 5 in water, hold 13 blow down gass from the ventilation of ventilation flue 2 and scavenge port 3, reaches the purpose of taking a breath in the water.This rebreather has been eliminated beginning swimmer's fear, the swimmer can be in water the long period recreation of playing, eliminate the water of choking, hidden danger such as drowned, be the protection apparatus that safety is breathed in a kind of water preferably.
