Abstract
The utility model relates to a suspension respirator comprising a mask 1, a breathing soft tube 2, and a floating body. The device is characterized in that the floating body consists of an air chamber 3, a water chamber 4 connected with the lower end of the air chamber 3 through the screw, and a control valve on the two sides of the upper part of the air chamber 3; therein, the air chamber 3 is communicated with the water chamber 4 through an automatic one-way valve 5; the control valve consists of the air chamber 3, a tee-joint connecting element 6 communicated with the breathing soft tube 2, an automatic spring 7 arranged on the lower part of the tee-joint connecting element 6, an automatic valve piece 8, a positioning bolt 9 of the automatic valve piece 8, a hand-held valve seat 10 arranged on the lower part of the tee-joint connecting element 6, and the hand-held hollow valve 11 arranged below the hand-held valve seat 10 and communicated with the outside. The utility model is simple in structure, easy in manufacture, convenient in carrying, and comfortable in use.
Description
Technical field
The utility model relates to a kind of diver's air feeder, particularly a kind of Suspension respirator.
Background technology
Existing diver's air feeder has high-pressure oxygen cylinder or air compressor, wherein high-pressure oxygen cylinder is made up of bottle, relief valve unit, face shield, connection hose, but the hyperbaric oxygen in the bottle is taken a breath in respiration with regard to the supplier after reducing pressure like this, but its bottle heaviness, carry inconvenience, and it must have the equipment of supporting with it fixedly can high pressure gas, and price is expensive, can not popularize; And the use of air compressor must be provided with a fixing workboat on the water surface, and by the plural people cooperation of constantly calming the anger, a complete set of equipment cost is also very expensive.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, be easy to make, Suspension respirator that cost is low.
The utility model is achieved in that a kind of Suspension respirator, comprise face shield, breathing hose, buoyancy aid, it is characterized in that: described buoyancy aid is made of air chamber, control valve body through screw thread and air chamber lower end bonded assembly hydroecium, both sides, air chamber top, and wherein air chamber is connected through automatic check valve with hydroecium; Control valve body is by the three-way connector that is communicated with air chamber, breathing hose, the fixing screw of opening spring, automatic valve block, automatic valve block certainly that the three-way connector below is provided with, the manual valve seat that the three-way connector below also is provided with, manually the manual coreless valve that can communicate with the external world of valve seat below constitutes.
It mainly is for buoyancy aid is kept perpendicular to the water surface that the utility model is provided with hydroecium, the state that air chamber makes progress, after manual coreless valve was closed in artificial turn, the breath carbon dioxide in the air chamber can so just can be supplied with the good air of human body by the water-soluble part of separating in the hydroecium as far as possible.
After the people puts on face shield, facial just can tightly cut off with extraneous, have only by breathing hose, automatic valve block be the three-way connector of opening, the manual coreless valve that communicates with the external world communicates with atmosphere and breathes; When water enters manual coreless valve, can make an end of automatic valve block come-up SELF CL three-way connector because of being subjected to the buoyancy of water effect, at this moment breathing can only be at breathing hose, valve block is between the three-way connector, air chamber of closed condition and carries out automatically; When extraordinary circumstances took place, manually manual coreless valve was closed in turn, and at this moment, buoyancy aid and ambient atmosphere are separated by, and breathed and also can only carry out between breathing hose, three-way connector, air chamber.
The utility model is simple in structure, is easy to make, and low cost of manufacture is easy to carry, and uses comfortable.
Description of drawings
The structural representation of Fig. 1, the utility model embodiment;
Fig. 2, be the structural representation of float among Fig. 1.
The specific embodiment
A kind of Suspension respirator, comprise face shield 1, breathing hose 2, buoyancy aid, it is characterized in that: described buoyancy aid is made of air chamber 3, control valve body through screw thread and air chamber 3 lower end bonded assembly hydroeciums 4, both sides, air chamber 3 top, and wherein air chamber 3 and hydroecium 4 are connected through check valve 5 automatically; Control valve body is by the three-way connector 6 that is communicated with air chamber 3, breathing hose 2, the fixing screw 9 of opening spring 7, automatic valve block 8, automatic valve block 8 certainly that three-way connector 6 belows are provided with, the manual valve seat 10 that three-way connector 6 belows also are provided with, manually the manual coreless valve that can communicate with the external world 11 of valve seat 10 belows constitutes.
