    摘要: A water hardness detection probe, sensor, detection method and water softener are provided. The sensor includes a control unit which includes a processing module and a potential detection module. The detection probe includes a first probe and a second probe. When the first and second probes are both exposed in raw water, a potential between the first and second probes is regarded as first potential. When the first probe is in the raw water and the second probe is in softened water, the potential between the first and second probes is regarded as the second potential. The potential detection module measures the potential between the first and second probes. The processing module determines the water hardness of the softened water according to a difference between the first potential and the second potential. The sensor can detect the water hardness of the water softener in real time and eliminate detection deviations.

    摘要: A water pH detection sensor and a use of a ruthenium-iridium electrode as a PH sensing material. The water pH detection sensor includes a ruthenium-iridium electrode and a reference electrode, and the pH value of a solution to be detected is obtained by means of a voltage between the ruthenium-iridium electrode and the reference electrode. The ruthenium-iridium electrode is used as the pH sensing material, the electrode potential of the material in a solution has a good linear correspondingly relationship with a hydrogen ion concentration, and the material has the features of a wide pH value response range, a high response speed, a stable response performance and repeated measurement and use, and is suitable for different practical application scenarios.

    摘要: A full-effective reverse osmosis membrane element and a water purification machine are provided. The reverse osmosis membrane element includes a reverse osmosis membrane (20) and a central tube (10) provided with several water-inlet holes (11). The reverse osmosis membrane (20) is wound around the central tube (10) and covers each water-inlet hole (11) and forms a raw water flow channel. Two sides of the reverse osmosis membrane (20) are sealed by first and second water division bands (21) (22). The first water division band (21) and the central tube (10) form a first concentrated water-outlet (211). The first water division band (21) and the reverse osmosis membrane (20) form a second concentrated water-outlet (212). The second water division band (22) and the reverse osmosis membrane (20) form a first raw water-inlet (221). The second water division band (22) and the central tube (10) form a second raw water-inlet (222).

    摘要: A full-effect reverse osmosis membrane element includes a central tube and a reverse osmosis membrane assembly wound around the central tube. The reverse osmosis membrane assembly includes a pair of reverse osmosis membranes attached at front surfaces thereof and wound around the central tube. A water feed channel has a water inlet formed at front edges of the reverse osmosis membranes and a water outlet formed at rear edges of the reverse osmosis membranes. A water division structure is arranged in the water feed channel, and includes a first water division band forming a preset space with the central tube when the reverse osmosis membranes are in an unfolded state. The first water division band divides the water feed channel into a first flow channel having a gradually decreasing cross-section and a second flow channel in communication with the first flow channel.
