[0002] Ultrapure water machine is a water treatment equipment that uses pretreatment, reverse osmosis technology, ultrapurification treatment and post-treatment methods to almost completely remove the conductive medium in the water, and remove the non-dissociated colloids, gases and organic matter in the water to a very low level.

[0003] The existing Chinese patent with authorization announcement number CN214702418U discloses a liquid level detection device for a water tank, including a liquid level pipe, both ends of the liquid level pipe are provided with a bend pipe, the bend pipe is connected to the water tank through a water diversion pipe; the liquid level pipe and the bend pipe are connected through a pipe body connection assembly, and the bend pipe and the water diversion pipe are connected through a pipe body connection assembly. The liquid level detection device for a water tank described in the utility model is connected to a water tank through a liquid level pipe, a bend pipe, and a water diversion pipe. The water in the water tank flows into the water diversion pipe by pressure, and then flows into the liquid level pipe. The water level in the liquid level pipe is consistent with the water level in the water tank, so that the staff can know the water level in the water tank by observing the liquid level in the liquid level pipe. Infrared sensors are provided at both ends of the liquid level pipe. The infrared sensors can remind the high and low water levels to prevent the liquid level from being too high or too low.

[0004] The disadvantage of the above-mentioned prior art solution is that the manufacturing cost of the device is relatively high because the infrared sensor is provided to remind the high and low water levels, and there is still room for improvement. Utility Model Content
