Detailed Description

As shown in fig. 1-3, the flushing device for ophthalmic care comprises a cold water pipe 1, a hot water pipe 2, a water mixing valve 3, a Y-shaped pipe 4 and a nozzle 5, wherein the cold water pipe 1 and the hot water pipe 2 are communicated with the water mixing valve 3, and the water mixing valve 3 is also communicated with the lower end of the Y-shaped pipe 4. The mixing valve 3 is a common pipe element, and functions to mix liquids entering from different pipes in a cavity of the mixing valve 3 to meet requirements. In the present embodiment, the function of the mixing valve 3 is to mix cold water and hot water to a suitable temperature. In order to facilitate observation of the temperature of the mixed water, a liquid temperature display 6 is installed outside the mixing valve 3 for detecting the temperature of the water in the mixing valve 3. A temperature sensor 7 is also arranged between the water mixing valve 3 and the Y-shaped pipe 4. The temperature sensor 7 is in signal connection with the liquid temperature display 6, and the temperature sensor 7 can select a single temperature sensor to be in signal connection with the liquid temperature display 6 or select an existing product with the temperature sensor 7 and the liquid temperature display 6 integrated. The water mixing valve 3 is a switch which can control the water inlet proportion and can mix the water inlet temperature. The water mixing valve 3 is common in life, such as a water faucet for controlling shower temperature, and when the opening degree of the water faucet is different, the temperature of outlet water is also different.

And two water outlet holes at the upper end of the Y-shaped pipe 4 are respectively provided with a spray head 5, and the spray head 5 comprises a rotating ball 50 and a spray pipe 51. The nozzle tube 51 is fixed to the rotary ball 50, and a first water outlet passage 52 is provided inside the rotary ball 50, and the first water outlet passage 52 is communicated with the nozzle tube 51. A spherical space is arranged at the top of the nozzle 5, and an opening 54 is arranged on the spherical space, and the opening 54 forms an included angle with the central axis of the nozzle 5. In the present embodiment, the angle between the opening 54 and the central axis of the nozzle head 5 is 60 °. The spray head 5 is provided with a second water outlet channel 53 communicated with the spherical space, and the first water outlet channel 52 is communicated with the second water outlet channel 53. The rotating ball 50 is tightly matched in the annular space, and the tight fit means that the rotating ball 50 can rotate in the spherical space according to a certain range and can ensure that the rotating ball 50 and the annular space can be sealed, so that the phenomenon of liquid leakage cannot be caused. The rotary ball 50 and the spray head 5 may be selected from copper metal or other materials that are not easily rusted, considering that the rotary ball 50 and the spray head 5 have a problem of rusting.

A stop ring 8 is further disposed at the opening 54, and the stop ring 8 is used for limiting the rotation angle of the rotating ball 50 and preventing the rotating ball 50 from falling out of the spherical space due to an excessively large rotation angle and causing damage. Preferably, the stop ring 8 is riveted to the opening 54.

The spray pipe 51 is in a funnel shape, one end of the spray pipe 51 with a small cross section is communicated with the first water outlet channel 52, the other end of the spray pipe 51 is fixed with the silica gel ring 9, and the silica gel ring 9 is in a ring shape and can cover the edge of the spray pipe 51. Preferably, the silicone ring 9 is detachable and replaceable. The effect of silica gel circle 9 prevents that the user from damaging the eye when using this device.

A fixing column 55 is further screwed below the spray head 5, a third water outlet channel 551 is arranged in the fixing column 55, threads are arranged at the upper end and the lower end of the fixing column 55, the upper end of the fixing column 55 is screwed with the spray head 5, and the lower end of the fixing column 55 is screwed with a water outlet hole at the upper end of the Y-shaped pipe 4. The third water outlet passage 551 communicates with the first water outlet passage 52 to keep the water flow smooth.

In the using process, the cold water pipe 1 and the hot water pipe 2 are respectively connected with a water source, cold water and hot water are mixed in the water mixing valve 3, the temperature of the mixed liquid is displayed through the temperature sensor 7 and the liquid temperature display 6, when the temperature does not meet the requirement, the water inlet speed of the cold water and the hot water can be adjusted through the water mixing valve 3, and when the temperature displayed by the liquid temperature display 6 meets the requirement, the mixed liquid can sequentially flow through the third water outlet channel 551, the second water outlet channel 53, the first water outlet channel 52 and the spray pipe 51. After a certain amount of mixed liquid is stored in the nozzle 51, the user sticks eyes to the silica gel ring 9. When the people of difference use this device, can adjust through angle and the range of adjusting the roating sphere 50 at spherical space internal rotation, the different users of adaptation that this device can be better, the distance between two shower nozzles 5 of adjustment satisfies the requirement of patient eye interval and promotes patient's use impression. In addition, the funnel-shaped spray pipe 51 can be used for quickly accumulating a certain amount of liquid at the bottom of the spray pipe 51, so that the speed of the liquid during gushing is relieved, and the liquid is prevented from exceeding the liquid level during gushing to hurt eyes.

The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
