This composite eyewasher with a voltage-stabilizing nozzle provides a full-function composite eyewasher combination, achieving relatively stable eyewash water output under unstable industrial water pressure, and at the same time having bathing, showering functions and stable pipelines. However, for this composite eyewasher with a voltage-stabilizing nozzle, the adjustment of water pressure is passive and cannot be actively adjusted, and the pipeline is not provided with a stable support structure, and the water pressure will cause the eyewasher to shake, affecting the stability of use.

The front end of the first connecting pipe is fixedly connected to a voltage stabilizing assembly. The front end of the voltage stabilizing assembly is fixedly connected to a second connecting pipe. An electronic pressure gauge is arranged outside the second connecting pipe. The voltage stabilizing assembly includes a fixed seat, a water outlet pipe, an inclined surface, a water inlet pipe, a sliding sleeve, a connecting rod, a plug column, a moving block, an adjusting seat, a lead screw, and a second motor.

[0007] Through the above technical solution, a voltage stabilizing assembly is provided, which cooperates with the water tank to stabilize the water flow input into the nozzle body. During use, the water tank is filled with clean water through the water delivery pipe. When in use, the water injection is stopped and the delivery pump is started to pump the clean water in the water tank out.

At this time, the cut-off area of the voltage-stabilizing component is the largest. When it is necessary to reduce the water flow pressure, the second motor is started to drive the screw rod to rotate, driving the moving block connected by threads to move forward along the adjusting seat. The sliding sleeve slides forward, driving the plug column to insert into the water outlet pipe. During this process, the plug column gradually approaches the inclined surface, and the cut-off area of the voltage-stabilizing component gradually decreases. The water flow velocity increases.

When in use, the water tank 3 is filled with clean water through the water delivery pipe 4. When in use, the water injection is stopped and the delivery pump 22 is started to pump out the clean water in the water tank 3. The water pressure is not related to the water pressure of the external pipeline, achieving the effect of voltage stabilization.

[0031] Specifically, the sliding sleeve 2405 is slidably connected to both the water outlet pipe 2402 and the water inlet pipe 2404, and the front end of the plug column 2407 is adapted to the inclined surface 2403.

When the sliding sleeve 2405 is in close contact with the water inlet pipe 2404, clear water enters from the water inlet pipe 2404, passes through the space between the plug column 2407 and the sliding sleeve 2405, and then is discharged from the water outlet pipe 2402 and input into the spray pipe 8 and the eyewash connecting pipe 11.

The advantages are that the driving mode of the screw rod 2410 has the characteristics of self-locking and anti-return, which is convenient for controlling the water flow pressure.

[0033] Embodiment 2: As Figures 2-5 shown, as an improvement to the previous embodiment.

[0034] Specifically, the lower end of the support 1 is fixedly connected with a support leg 2, the upper end of the water tank 3 is fixedly connected with a water delivery pipe 4, the rear end of the water tank 3 is fixedly connected with a drain pipe 5, the front end of the second connecting pipe 25 is fixedly connected with the rear port of the three-way solenoid valve 10, and the waterproof controller 17 is electrically connected to the three-way solenoid valve 10, the first motor 21 and the delivery pump 22.

The advantages are that the screw rod 19 and the support frame 15 are provided. When the user needs to wash the eyes with the eyewash nozzle pipe 13, according to the user's height, the first motor 21 is started to drive the screw rod 19 to rotate, driving the support frame 15 to move up or down along the sliding column 20 until the water tank 14 and the eyewash nozzle pipe 13 reach a height matching the user's height. The hose 12 is provided and can be bent without affecting the mobility of the eyewash nozzle pipe 13.

[0036] Specifically, the electronic pressure gauge 26 and the second motor 2411 are both electrically connected to an external cloud control terminal. The advantage is that the electronic pressure gauge 26 is provided. The electronic pressure gauge 26 monitors the water flow pressure in the second connecting pipe 25 in real time and transmits the pressure data to the cloud control terminal. The user sets a preset pressure value at the cloud control terminal. When the pressure data is greater than the preset pressure value, the second motor 2411 is started to stabilize the water pressure.

[0037] Working principle: During use, the water tank 3 is filled with clean water through the water delivery pipe 4. When washing the eyes, the water injection is stopped and the three-way solenoid valve 10 is controlled by the waterproof controller 17 to control the water flow direction to the spray pipe 8. The waterproof controller 17 starts the delivery pump 22 to pump the clean water in the water tank 3 out. The electronic pressure gauge 26 monitors the water flow pressure in the second connecting pipe 25 in real time and transmits the pressure data to the cloud control terminal. The user sets a preset pressure value at the cloud control terminal. When the pressure data is greater than the preset pressure value, the second motor 2411 is started to drive the screw rod 2410 to rotate, driving the moving block 2408 connected by threads to move forward along the adjusting seat 2409. The sliding sleeve 2405 slides forward, driving the plug column 2407 to insert into the water outlet pipe 2402. During this process, the plug column 2407 gradually approaches the inclined surface 2403, and the cross-sectional area of the voltage stabilizing component 24 gradually decreases, and the water flow velocity increases. According to Bernoulli's principle, the kinetic energy of the water flow increases and the pressure will decrease. The stable water flow sprays out from the nozzle body 9. When the user needs to wash the eyes with the eye wash nozzle pipe 13, according to the user's height, the first motor 21 is started to drive the screw rod 19 to rotate, driving the support frame 15 to move up or down along the sliding column 20 until the water tank 14 and the eye wash nozzle pipe 13 reach a height matching the user's height for easy use. The clean water in the water tank 3 is transported by the delivery pump 22, and the water pressure is not related to the water pressure of the external pipeline, achieving the effect of stabilizing the pressure.
