Description
Technical field
The present invention relates to Protection Product technical field, particularly relate to a kind of Cooling vest.
Background technology
In the high temperature or field work situation of the much equipment that can not install an air-conditioner, serious heat stress makes the functions such as the body heat regulation especially of the physiological function of people, water-electrolyte metabolism, blood circulation all can occur abnormal change, light then reduce operating efficiency, affect judgment, serious meeting causes heatstroke, even threat to life safety.For solving the problem, Cooling vest arises at the historic moment.
The Cooling vest of existing employing cooling water circulation, what adopt is that cooling tube is wrapped in Cooling vest, or film is set and is wrapped in waist, and pipeline is set in film to realize cooling water circulation, this Cooling vest, have poor air permeability, cooling area distribution uneven, simultaneously heavy, wear uncomfortable, rely on the shortcomings such as water source simultaneously.
The mode of adding low-temperature receiver in vest is separately had to realize cooling.This Cooling vest can freely be carried with, and is applicable to wearing next to the skin, and cold distributes evenly, recycle by adding low-temperature receiver, volume is little, lightweight, without worry of bearing a heavy burden, but this Cooling vest cooling efficiency is low, especially in higher temperature environment, low-temperature receiver can be consumed, and the cooling-down effect duration is shorter, especially in the wild, low-temperature receiver cannot long-time storage and short time recovery.
Therefore the individual temp .-lowering heatstroke vest needed badly as hot operation personnel, field man provide a kind of lightweight, safety and health temp effect good.
Summary of the invention
The object of the invention is hot operation personnel, field man provide a kind of lightweight, individual temp .-lowering heatstroke vest that safety and health temp effect is good, concrete summary of the invention is as follows:
A kind of Cooling vest, it is characterized in that comprising vest body, holding vessel and mozzle, described vest body is connected by mozzle with holding vessel, and described holding vessel is provided with holding vessel switch, and stores low-temperature receiver; The tank body perforate of described holding vessel, described tapping is provided with pressure relief device.Design like this, when human body feels sweltering heat, opens holding vessel switch, and pressure reduces, and part low-temperature receiver enters vest body and health carries out heat exchange, plays the effect reducing human body temperature., when can avoid working under the high temperature conditions, there is the excessive danger causing tank body to explode of pressure in tank body in the setting of pressure relief device.
Further, described pressure relief device comprises elastic device and sealing device; Described sealing device and tank body tapping hole wall are tightly connected; Described elastic device comprises elastomer and Connection Block, and described Connection Block is fixedly connected with storage tank body; Described elastomer one end is connected with Connection Block, and one end is connected with sealing device., when can avoid working under the high temperature conditions, there is the excessive danger causing tank body to explode of pressure in tank body in setting like this.When pressure is higher than elastomeric pulling force, sealing device is under the influence of air pressure along tank skin outwards movement, until finally depart from tank skin completely, release gas carries out pressure release, avoids blast.When sealing device and tank body tapping depart from completely, the pulling force of spring is less than and the limiting pressure of exploding close to tank body.
Further, described pressure relief device comprises body, elastic device and sealing device; Described body is cavity body structure, and described elastic device and sealing device are installed in body, and described sealing device is connected with body inner wall sealing; Described elastic device comprises elastomer and Connection Block, and described Connection Block is fixedly connected on body; Described elastomer one end is connected with Connection Block, and one end is connected with sealing device; Described body and holding vessel pass through detachably, are tightly connected., when can avoid working under the high temperature conditions, there is the excessive danger causing tank body to explode of pressure in tank body in setting like this.Elastomer can owing to making elastic force change by the impact of low temperature for a long time, and elastomeric degradation then means that holding vessel can not re-use.Setting like this, just can increase the service life of holding vessel, during replacing, only needs to change elastomer and sealing device, changes pressure relief device at most.As mentioned above, during now pressure release, elastomeric pulling force is less than and the limiting pressure of exploding close to tank body.
Further, described low-temperature receiver is liquid carbon dioxide.Liquid carbon dioxide is a kind of cold-producing medium, can absorb a large amount of heat during evaporation, and its heat of vaporization is 578kJ/kg.Carbon dioxide is nontoxic, and discharge does not pollute the environment, simultaneously liquid carbon dioxide low price.
Further, described holding vessel is provided with pressure-reducing valve, and described pressure-reducing valve is connected by attaching nut with holding vessel.
