New design – New patented  eyewash station

Description

A desktop double-head eyewash station for laboratories

Technical field
The utility model relates to the field of eye washers, in particular to a desktop double-eye eye washer used in laboratories.

Background technique

The eyewash station is a safety and labor protection equipment, and an emergency and protective facility for situations where there is contact with toxic and corrosive substances such as acids, alkalis, and organic substances. When the eyes or bodies of on-site workers come into contact with toxic, harmful or other corrosive chemicals, the eyewash station can provide emergency flushing or showering of the eyes and body, mainly to prevent further harm to the human body caused by chemical substances.

For example, a hand-push eyewash device is proposed. This component can be controlled to take a shower or clean the eyes individually through a three-way valve connector. It is easy to use and can be easily controlled through the first hand-push valve. The eyewash branch pipe and eyewash nozzle installed on the eyewash pipe can flush both eyes at the same time, and the rinsed water is concentrated through the eyewash basin, which is easy to use. The interior of the three-way valve connector uses a three-way ball valve, which has a simple structure, small size, and It is light in weight, tight and reliable, and has good sealing performance. The outer wall of the eyewash tube is also equipped with a second hand-push valve for control, which is convenient for control. However, when the eyewash device is in use, laboratory personnel need to manually push the first hand-push valve. It is not convenient to quickly clean the eyes later.

Description

Utility model content,

In view of the problems mentioned in the background art, the purpose of this utility model is to provide a desktop double-head eyewash station for use in laboratories to solve the problems mentioned in the background art.

The above technical objectives of the present invention are achieved through the following technical solutions:
A desktop double-head eyewash station for laboratories, including: a placement block, a collection trough is provided on the top surface of the placement block, and a fixing hole is provided on the bottom surface inside the collection trough; a water inlet pipe, the water inlet pipe is provided in Inside the fixed hole, the top end of the water inlet pipe is fixedly connected with an eyewash branch pipe; a water supply component is provided on the bottom surface of the water inlet pipe for transporting eyewash water.

By adopting the above technical solution and setting up a water supply component, the water supply component can automatically send cleaning water into the interior of the eyewash branch pipe, which facilitates quick water user eye cleaning in the future.
Preferably, the water delivery component includes: a solenoid valve, which is fixedly connected to the bottom end of the water inlet pipe; two eyewash nozzles are fixedly connected to the interior of the eyewash branch pipe; a control slot, which is located at The outer circular wall of the eyewash branch pipe and the inside of the control tank are fixedly connected with an infrared induction switch, and the infrared induction switch is electrically connected to the solenoid valve; a heating element, the heating element is arranged inside the water inlet pipe, Used to heat eyewash water.

By adopting the above technical solution and installing a heating element, when the eyewash cleaning water enters the inside of the water inlet pipe, the heating element can heat the cleaning water to prevent the temperature of the cleaning water sprayed from the eyewash nozzle from being too low.

Preferably, the heating element includes: a fixed groove, which is opened on the inner circular wall of the water inlet pipe; a heating wire is fixedly connected to the inside of the fixed groove; and a recovery pipe, which is fixedly connected to the water inlet pipe. On the inner circular wall surface of the fixed hole, the recovery pipe and the water inlet pipe are movablely sleeved together.

By adopting the above technical solution, the opening or closing of the solenoid valve is controlled by the infrared induction switch, so that the cleaning water can be sent into the interior of the eyewash branch pipe through the water inlet pipe, so that the water inside the eyewash branch pipe can be sprayed out through the eyewash nozzle, thereby facilitating infrared After the sensor switch senses the position of the user’s head, the cleaning water can be sprayed directly through the eyewash nozzle to facilitate quick cleaning of the user’s eyes later.

Working principle:

Please refer to Figures 1 to 4. During use, by setting the infrared sensor switch 9, when the experimenter aligns his eyes with the position of the eyewash nozzle 7, the infrared sensor switch 9 can sense the position of the experimenter’s head. , the opening or closing of the solenoid valve 6 is controlled by the infrared induction switch 9, so that the cleaning water can be sent into the interior of the eyewash branch pipe 5 through the water inlet pipe 4, so that the water inside the eyewash branch pipe 5 can be sprayed out through the eyewash nozzle 7, thus facilitating After the infrared sensor switch 9 senses the position of the user’s head, the cleaning water can be sprayed directly through the eyewash nozzle 7 to facilitate quick cleaning of the user’s eyes later. By setting the heating wire 11, when the cleaning water passes through When the water inlet pipe 4 enters the eyewash branch pipe 5, the heating wire 11 can heat the cleaning water to prevent the cleaning water sprayed from the eyewash nozzle 7 from being too low in temperature. By setting the support ring 14, the staff can move the support ring 14 After being placed on the laboratory desktop, bolts are used in conjunction with the threaded holes 15 to facilitate the later fixation of the support ring 14 on the laboratory desktop to fix the placement block 1. By setting the recovery pipe 12, cleaning after use Water can be collected through the recovery pipe 12.
