Abstract

The invention relates to a detection device for the original water tank liquid level of an RO water purification machine. The detection device comprises an original water tank (1), a filter element assembly (2), a booster pump (4), a reverse osmosis RO film (6) and a water purification tank (6) which are connected in sequence through pipelines, a signal amplifier (7) and a control panel (8). A liquid level meter (9) is mounted inside the water purification tank, the input end of the signal amplifier is connected with the booster pump, the output end of the signal amplifier is connected with the control panel, the booster pump is connected with the control panel through a current signal line, and the liquid level meter is connected with the control panel through a liquid level meter signal line (11). The invention also provides a detection method of the detection device, the liquid level of the original water tank is judged by detecting the current magnitude of the booster pump, and the liquid level meter does not need to be mounted in the original water tank any longer, so that the structure of the original water tank is optimized, the risk of accidents caused by the failure of a traditional liquid level meter is avoided, and the cost of the whole machine is reduced.

Description

technical field [0001] The invention relates to a detection device for the liquid level of a raw water tank of an RO pure water machine, belonging to the technical field of drinking water treatment equipment. Background technique [0002] The reverse osmosis pure water machine is a device that integrates microfiltration, adsorption, ultrafiltration, reverse osmosis, ultraviolet sterilization, ultra-purification and other technologies to directly convert tap water into ultra-pure water. The RO pure water machine is a water purifier that uses the principle of reverse osmosis technology to filter water. Its principle is that under a certain pressure, water molecules can pass through the RO membrane, while impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, and viruses in the source water cannot pass through the RO membrane, so that part of the water passes through the RO membrane. The membrane is separated, and the non-permeated water form...
