Description
Technical field
The present invention relates to oxygen cabin technical fields, more particularly, to a kind of multi-orifice showerhead and hyperbaric oxygen chamber.
Background technique
Existing glass marble fire-fighting spraying head is a kind of common fire-fighting spraying head, and heat-sensitive element is glass marble, when outer
When boundary's temperature is higher than highest threshold values, glass marble is broken, opens fire-fighting spraying head, achievees the purpose that fire extinguishing.But such fire-fighting spray
Drenching head, there are the following problems:
1, it to guarantee that spray head works normally, stretches out except room furred ceiling when installation, when carrying out interior decoration or carry big part
It is careless slightly whens kinds of goods etc., it is possible to mutually to collide with spray head, so as to cause spray head crack damage, make watery in high pressure
The spray head of state occurs spraying water outside because of rupture, the indoor kinds of goods and floor etc. be drenched, to cause great economy
Loss；
2, after fire is extinguished, spray head cannot be automatically closed, and cause water resource waste and big water damage；It sprays simultaneously
It can not be reused after head rupture, new spray head need to be re-replaced, the wasting of resources is at high cost；In addition, institute after spray head rupture
The fire water of the pipeline at place is still in high pressure conditions, it is difficult to which fire-fighting need to be installed by being directly screwed to new fire-fighting spraying head by manpower
On the water supply branch pipe of spray head, so, it needs to cut off to pipe network locating for the damage fire-fighting spraying head when replacing fire-fighting spraying head
Fire water supply, and the water of pipe network locating for the damage fire-fighting spraying head is discharged, then again will by the tools such as wrench
New fire-fighting spraying head is screwed on the water supply branch pipe that need to install fire-fighting spraying head, but the pipe as locating for the fire-fighting spraying head of damage
Net larger, the draining before replacing fire-fighting spraying head will necessarily lose a large amount of water resource, and spray from draining to by new fire-fighting
Leaching head is installed to be needed to take a substantial amount of time on corresponding water supply branch pipe；
3, after shower water is opened, water sputtering is scatter by water by splash box, but due to spraying and rebounding from spray head to splashing
Water on water pond forms fixed parabola, therefore the limited area of water covering, especially for some areas immediately below spray head
Domain can not cover.
Summary of the invention
The object of the invention is that it is big to have overcome the deficiencies of the prior art and provide a kind of spray area, can reuse,
Save the cost saves the multi-orifice showerhead of water resource.To achieve the goals above, the present invention provides a kind of multi-orifice showerhead,
Including hollow housing；The multiple nozzles being equipped with along the hollow housing outer surface；The lid conjunction hollow housing has hole cap；If
