The utility model relates to the technical field of eye washer equipment, specifically a kind of spray eye washer that can self-control alarm. Background technology
Eye washer is when poisonous and harmful substance (such as chemical liquid etc.) splashes to staff body, face, eye or breaks out of fire and causes staff’s clothing to catch fire, is used in case of emergency, temporarily slows down harmful substance to health. Further violations, further treatment and treatment need to follow the doctor’s guidance to avoid or reduce unnecessary accidents.
Eyewash and shower equipment are emergency rescue facilities used under toxic, harmful and dangerous working environment. When the eyes or body of on-site operators are exposed to toxic, harmful and other corrosive chemicals, the eyewash device can use these devices to flush or rinse the eyes and body urgently, mainly to avoid further damage to the human body caused by chemicals.
And can find when using this equipment, usually when needing to use the eyewasher all run into emergencies such as chemical leakage etc., therefore need to carry out to the outside world simultaneously when relevant personnel cleans self by eyewasher The warning achieves the effect of reducing losses, but the equipment with this function on the market is still relatively lacking, and the existing existing equipment uses electric alarm bells, which not only require personnel to perform additional operations on them, but also affect their own cleaning. In addition, due to The frequency of use of the eyewash is low. To ensure that the electric alarm bell is in a standby state, it is necessary to maintain power consumption at all times, which wastes resources.

 (2) The nozzle and the shower between the angle of 40 ~ 90 °, personnel in the cleaning, standing between the nozzle and the shower, when switching the use of the shower and the spray head without changing their position can be used, more convenient and convenient.
 (3) The utility model in the nozzle is provided with two, two nozzles work simultaneously to clean the user’s eyes, greatly improving the cleaning efficiency.
Description of the drawings
 FIG. 1 is the structure of the present utility model is not intended;
 FIG. 2 is a schematic view of the impeller structure.
 The following will be combined with the accompanying drawings in the embodiment of the present invention, the technical solution in the embodiment of the present invention is clearly and completely described, obviously, the described embodiment is only a part of the embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without performing creative labor fall within the scope of the protection of the present invention.
 Referring to FIG. 1, the present invention provides a technical solution: a self-controlled alarm spray eyewash, the main body is an eyewash, the eyewash includes an inlet pipe 1, a three-way valve 2, an eyewash basin 3, a nozzle 4, a shower 5 and an alarm bell 6, one end of the inlet pipe I is conducted with an external water source, the other end is connected to the inlet of the three-way valve 2, the other two outlets of the three-way valve 2 are connected to the nozzle 4 and the shower 5, the eyewash basin 3 is provided directly below the nozzle 4, and the shower head 4 is provided with a shower 5 above, The three-way valve 2 is provided with a control valve 7 and an adjustment knob 8, and the inlet of the three-way valve 2 is provided with an impeller 9, and the impeller 9 is connected with an alarm bell 6 fixed on the side wall of the three-way valve 2. Its structure is simple, improved on the basis of the structure of the traditional eyewash, can accompany the eyewash to work, through the water flow to drive the impeller 9 way to control the alarm bell ringing to achieve alarm, personnel in their own cleaning at the same time do not need to operate the alarm device, for their own cleaning time at the same time can quickly notify the surrounding personnel, play a warning role, has a high practical value. And in use, when routine monitoring of the equipment is required, the alarm bell can be adjusted to the outside for water discharge test.
 wherein the nozzle 4 and the shower 5 between the angle of 40 ~ 90 °. When the personnel are cleaning, standing between the nozzle 4 and the shower 5, when switching the use state of the shower 4 and the shower head 5, they can use it without changing their position, which is more convenient and convenient.
