The PPC cartridge is commonly referred to as a Pressure differential cartridge (Pressure DIFFERENTIAL CARTRIDGE). The filter cartridge is a device for filtering liquids or gases that is effective in removing impurities, particulates and other contaminants, ensuring that the liquid or gas flowing therethrough is relatively clean.

RO cartridge refers to a reverse osmosis cartridge (Reverse Osmos IS CARTRIDGE) commonly used in reverse osmosis water treatment systems. Reverse osmosis is a technique for filtering water through a semipermeable membrane, and an RO cartridge is one of the core components in this system. The RO cartridge filters water through a semipermeable membrane to remove ions, microorganisms, organic substances, heavy metals and other dissolved substances from the water, thereby producing high purity water. The technology can effectively remove a plurality of solid particles and dissolved matters dissolved in water, so that the water is clearer and cleaner, and is suitable for various fields including drinking water, industrial water, medical water and the like.

The C filter cartridge, i.e., the carbon filter cartridge, is a common filter cartridge type that uses activated carbon as the filter medium. The filter element can effectively remove peculiar smell, chlorine, organic compounds and other pollutants in water. The activated carbon has strong adsorption performance and can adsorb and capture a plurality of harmful substances in water, so that the activated carbon is widely applied to water treatment and air purification.

The miniature water pump is a miniature water pump 21 for supplying water to the instant heating module and discharging boiled water and hot water with various temperature and water temperature. The instant heating module 20 adopts an anhydrous box combination, the pressure of the inlet of the module is reduced by a pressure reducing valve 22, and water is pumped into the instant heating module 20 by a miniature water pump 21 to output boiled water and hot water with various temperature and water temperature.
