【detailed description】

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Specific embodiment 1

As shown in FIG. 1 , the utility model provides an electrolysis water machine capable of accurately detecting the PH value of water. The electrolysis water machine comprises a filtering device 1 , an electrolytic cell 2 and a water discharging device 6 , and the filtering device 1 is connected at one end. The other end of the inlet pipe is connected to the electrolytic cell 2. A buffer tank 4 is connected between the electrolytic cell 2 and the water discharge device 6, and a PH sensor 5 is disposed in the buffer tank 4.

The function of the buffer tank 4: If the buffer tank 4 is not provided, the PH sensor 5 is disposed in the electrolytic cell 2. When electrolysis, the PH sensor 5 is affected, and the measured PH value may not be accurate enough, causing the user to drink Substandard water affects your health.

The electrolysis tank 2 of the electrolysis water machine is further provided with a heating device, which may be a heating device such as an electromagnetic induction heater, a heating tank or a quartz heating tube. The heating device heats the water to the most comfortable drinking temperature for the user to make the user more comfortable. In addition, the constant temperature of the water in a temperature range makes the PH sensor 5 test more accurate and does not drift.

The water ionizer is further provided with a control panel 7 having various functional operation keys, and the control panel further includes a display screen for displaying test results. The control panel 7 is a touch control panel, and the corresponding function operation can be realized by tapping the function menu of the finger, which is convenient and quick, and has good visibility.
