Technical Field

This utility model relates to shower eye washers, and particularly to a new type of automatic drainage shower eye washer.

Background Technology

A shower eye washer is a new type of essential safety and labor protection device, and is an essential emergency rinsing device in situations involving contact with acids, alkali, organic substances, and other toxic and corrosive substances. When on-site workers’ eyes or bodies come into contact with toxic chemical substances, causing accidental injuries, this product can quickly shower and rinse, reducing the degree of injury to the minimum.

Pada masa ini, most shower eye washers on the market use two manual ball valves to separately control the eye washing and showering functions. When the eye-washing push valve or shower valve is opened, water flows through the inlet pipe into the eye washer and is sent to the eye-washing spray head or shower head, and sprayed out through the eye-washing spray head and shower head. selepas pembersihan, the push valve or shower valve is closed, and the inlet pipe stops supplying water to the eye-washing spray head and the shower head. Walau bagaimanapun, the water that has not been sprayed out will accumulate in the internal pipeline of the eye washer. In cold places in the north, many eye washers are used at temperatures below 0 darjah, and the water accumulated in the pipe will freeze. The eye washer cannot be used normally, and if an accident occurs, the best rescue opportunity will be lost, posing a serious safety risk.

Utility Model Content

The purpose of this utility model is to provide a new type of automatic drainage shower eye washer, to solve one or more of the above-mentioned technical problems.

According to one aspect of this utility model, a new type of automatic drainage shower eye washer is provided, including an inlet pipe, a shower water pipe, an eye-washing water pipe, and a drainage pipe. The inlet pipe is separately connected to the shower water pipe and the eye-washing water pipe, and the drain pipe is separately connected to the shower water pipe and the eye-washing water pipe. The connection point of the shower water pipe and the inlet pipe has a first valve, and the connection point of the eye-washing water pipe and the inlet pipe has a second valve. A draining device is installed inside the drain pipe. The draining device includes a first shoulder, a second shoulder, a spring, and a ball. The first shoulder and the second shoulder are located on the inner wall of the drain pipe. One end of the spring is located at the first shoulder, and the other end is connected to the ball. When the spring is in its natural state, the ball is far from the second shoulder. When the spring is compressed, the ball is attached to the second shoulder to close the drain pipe.

This utility model solves the problem that ordinary eye washers cannot prevent freezing by setting up a drainage device, which can automatically drain the water accumulated in the shower eye washer, without manual operation, automatically drain it, reduce the workload of workers, and eliminate safety hazards.

In some embodiments, the drain pipe includes a shower drain pipe, an eye-washing drain pipe, and a main drain pipe. The shower drain pipe is connected to the shower water pipe, the eye-washing drain pipe is connected to the eye-washing water pipe, and the main drain pipe is connected to the shower drain pipe and the eye-washing drain pipe. This can automatically drain the water accumulated in the shower eye washer.

In some embodiments, the shower drain pipe is equipped with a drainage device, and the eye-washing drain pipe is equipped with a drainage device. This can automatically drain the water accumulated in the shower eye washer.

Specific Implementation

The following is a further detailed description of this utility model in conjunction with the attached drawings.

As shown in Figures 1-4, the new type of automatic drainage shower eye washer includes an inlet pipe 1, a shower water pipe 2, an eye-washing water pipe 3, and a drain pipe 4. Paip masuk 1 is separately connected to the shower water pipe 2 and the eye-washing water pipe 3 through a three-way pipe. The drain pipe 4 is separately connected to the shower water pipe 2 and the eye-washing water pipe 3. In this embodiment, the drain pipe 4 includes a shower drain pipe 41, an eye-washing drain pipe 42, and amain drain pipe 43. The shower drain pipe 41 is connected to the shower water pipe 2 through a three-way pipe, the eye-washing drain pipe 42 is connected to the eye-washing water pipe 3 through a three-way pipe, and one end of the main drain pipe 43 is connected to one end of the shower drain pipe 41 and the eye-washing drain pipe 42 each through a three-way pipe.

The connection point of the shower water pipe 2 and the inlet pipe 1 is threaded with a first valve 5. The first valve 5 is used to control the switch of the shower water pipe 2. The connection point of the eye-washing water pipe 3 and the inlet pipe 1 is threaded with a second valve 6. The second valve 6 is used to control the switch of the eye-washing water pipe 3. A drainage device 7 is installed inside the drain pipe 4. The drainage device 7 is used to drain the remaining water in the shower water pipe 2 and the eye-washing water pipe 3 to prevent freezing and blockage of the water pipe. In this embodiment, a drainage device 7 is installed in both the shower drain pipe 41 and the eye-washing drain pipe 42.

The drainage device 7 includes a first shoulder 71, a second shoulder 72, a spring 73, and a ball 74. The first shoulder 71 and the second shoulder 72 are both integrally formed on the inner wall of the drain pipe 4, with the first shoulder 71 being closer to the main drain pipe 43 than the second shoulder 72. One end of the spring 73 is fixedly connected to the first shoulder 71, and the other end of the spring 73 is connected to the ball 74. When the spring 73 is in its natural state, the ball 74 is far from the second shoulder 72. When the spring 73 is compressed, the ball 74 is attached to the second shoulder 72, closing the drain pipe 4.

In practical use, open the first valve 5 or the second valve 6 for showering or eye washing. The water flows through the inlet pipe 1 into the shower water pipe 2, the eye-washing water pipe 3, and the drain pipe 4. Pada masa ini, the water flowing to the drain pipe 4 presses the ball 74 and the spring 73 through water pressure. The spring 73 is compressed, and the ball 74 is attached to the second shoulder 72, closing the drain pipe 4. When the use is over, close the valve, and the water flow stops. The water pressure applied to the spring 73 and the ball 74 greatly weakens, the spring 73 returns to its normal state, and the ball is far from the second shoulder 72. The water remaining in the shower water pipe 2 and the eye-washing water pipe 3 flows out through the drain pipe 4, thereby timely draining the water in the shower water pipe 2 and the eye-washing water pipe 3 to prevent freezing in cold weather.

Secara ringkas, this utility model solves the problem that ordinary eye-washers cannot prevent freezing by setting up a drainage device, which can automatically drain the water accumulated in the shower eye-washer, without manual operation, automatically drain it, reduce the workload of workers, and eliminate safety hazards.

The above only describes the new implementation methods of this utility model. It should be pointed out that for those ordinary technical persons in this field, several similar modifications and improvements can be made without departing from the creative concept of this utility model, and these should also be regarded as within the scope of protection of this utility model.
