An emergency eye wash and face wash nozzle

Abstract

The invention provides an emergency spray head for cleaning eyes and faces. The spray head comprises a spray head base, a nozzle, a dust-proof turning cover, an automatic inlet flow adjusting device and an outlet flow velocity buffer, wherein the spray head base is provided with a liquid inlet and a liquid outlet; the nozzle comprises a plurality of first spraying holes and is connected with the spray head base; the dust-proof turning cover is connected with the nozzle; the automatic inlet flow adjusting device is arranged at one end of the liquid inlet of the spray head base and used for adjusting the flow of a cleaning fluid flowing from the liquid inlet into the spray head base; and the outlet flow velocity buffer is arranged at one end of the liquid outlet of the spray head base and used for buffering the flow velocity of the cleaning fluid, which is adjusted by the automatic inlet flow adjusting device, in the spray head base. Compared with the prior art, the emergency spray head for cleaning the eyes and the faces has the advantages that the automatic inlet flow adjusting device and the outlet flow velocity buffer are equipped, so that the flow velocity of the fluid at the spray head outlet is quite gentle, the eyes of persons are not hurt, and cleaning effects of the faces and the eyes can still be guaranteed when the pressure and the flow of the spray head inlet are changed as follows.

Description

technical field [0001] The invention relates to a nozzle, in particular to an emergency eye-washing and face-washing nozzle. Background technique [0002] The cleaning coverage of the existing eyewash and face wash nozzles is very small. In fact, they can only wash the eyes, and cannot really clean the eyes and face at the same time. [0003] The water flow rate of the outlet of the existing eyewash and face wash nozzles is very fast, which may damage people's eyes. When the pressure and flow at the nozzle inlet change as follows, the following phenomena may occur: [0004] a. If the nozzle is used alone, if the inlet pressure of the eyewash device fluctuates within the operating pressure range, it will inevitably lead to obvious changes in the flow rate at the outlet of the nozzle, which will affect the effect of eyewashing and facewashing. [0005] b. When the shower nozzle and the eye wash nozzle are used at the same time, the water flow of the existing eye wash and fac...

Problems solved by technology

[0004] a. If the nozzle is used alone, if the inlet pressure of the eyewash device fluctuates within the operating pressure range, it will inevitably lead to obvious changes in the flow rate at the outlet of the nozzle, which will affect the effect of eyewashing and facewashing

[0005] b. When the shower nozzle and the eye wash nozzle are used at the same time, the water flow of the existing eye wash and face wash nozzle will inevitably be greatly diverted by the use of the shower nozzle, resulting in the outlet flow rate of the eye wash and face wash nozzle being too slow, unable to effectively clean people face
