Abstract
A temp-lowering device for oxygen respirator is composed of left and right end openings, protecting sleeve, internal and external tanks, coolant, supporter, side end opening and plug.
Description
The utility model is the suction temperature that is used for reducing oxygen breathing apparatus work, makes the wearer feel more comfortable device.
Four hours oxygen breathing apparatus heat sinks of existing domestic production are cylindrical, inside and outside jar forms interlayer and becomes gas channel, passage is shorter, be unfavorable for that gas fully cools off and volume is less, needed to change primary coolant after working 2 hours, cooling agent adopts ice cube, and suction temperature is below 38 ℃ when normal temperature medium work intensity.All do not establish reservoir in the oxygen breathing apparatus heat sink both domestic and external, cooling water is entered breathe the storehouse, increased respiratory resistance.
The purpose of this utility model provides a kind of good cooling effect, a kind of oxygen breathing apparatus heat sink that inspiratory resistance is little, simple in structure, easy to operate.
The purpose of this utility model is achieved in that side ports (7) is connected with the breathing storehouse, left port (1) is connected with inhaling hose, in become the passage of air-flow between jar (3) and outer jar (4) by support (6) supporting and shape forming cavity, cooling agent (5) directly from right output port (8) add be stored in in the jar.
Cooling agent adopts blue ice (adding primary coolant when only dispatching from the factory) suction temperature to be no more than 35 ℃.
At the right-hand member of heat sink, constitute a bigger space reservoir by interior jar, outer jar, right output port.
The utlity model has simple in structure, easy to operate, good cooling effect, advantage that inspiratory resistance is low.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the heat sink structure chart.
1, left port 2, protective sleeve 3, interior jar 4, outer jar 5, cooling agent 6, support 7, side ports 8, right output port 9, plug 10, reservoir
Side ports 7 is connected with the breathing storehouse, left port 1 is connected with inhaling hose, in jars 3 with outer jar 4 between support the shape forming cavity and become the passage of air-flow by support 6, cooling agent 5 directly is stored in interior jar from right output port 8 addings, at the right-hand member of falling unit by interior jar, outer jar, right output port constitutes a bigger empty same reservoir, cooling agent adopts blue ice, no matter the wearer is at normal temperature or in hot environment work, suction temperature all is no more than 35 ℃, arrow is represented gas flow direction among the figure, enter heat sink from breathing the high-temperature gas of coming in the storehouse by side ports, gas is through the heat sink passage, the agent that is cooled of a large amount of heats absorbs, gas is cooled, thereby reduced suction temperature, because the carbon dioxide generation chemical reaction that carbon-dioxide absorbent and human body are breathed out, not only can produce a large amount of heats, also can produce a part of water, the gas chance is cold during gas process heat sink passage also can produce a part of water, be stored in the reservoir of heat sink, its maximum pondage is 180ml, makes to breathe in the storehouse no longer storage of water, thereby reduced respiratory resistance, made the wearer feel more comfortable.
Claims (3)
1, a kind of oxygen breathing apparatus heat sink, it is characterized in that side ports (7) is connected with the breathing storehouse, left port (1) is connected with inhaling hose, in become the passage of air-flow between jar (3) and outer jar (4) by support (6) supporting and shape forming cavity, cooling agent (5) directly from right output port (8) add be stored in in the jar.
2,, it is characterized in that cooling agent adopts blue ice according to the described oxygen breathing apparatus heat sink of claim 1.
3, according to the described oxygen breathing apparatus heat sink of claim 1, it is characterized in that right-hand member, constitute a bigger space reservoir by interior jar, outer jar, right output port at heat sink.
