Abstract: A swimming pool filter element capable of automatically dosing. The swimming pool filter element includes a folding filter element and a doser filter element. The folding filter element includes a filter membrane and end covers, the end covers each having an upper end cover and a lower end cover. A wrench cover is arranged at the upper end of the upper end cover. The doser filter element includes a doser end cover, a doser lining and a doser shell. The doser filter element is added into the folding filter element, so that a water flow needing to be filtered firstly passes through the filter membrane of the folding filter element, solid large-particle impurities are filtered out, then the water flow enters the doser filter element and makes contact with sterilization tablets placed in the doser filter element, the tablets are dissolved, and finally water with dissolved tablets is discharged into a swimming pool.

Abstract: A water purifier, including a connector assembly including a connector body and a flange portion; the connector body includes the first water inlet cavity and the first water outlet cavity; the flange portion is provided with a flange hole; a filter element assembly including an end cover, the outer wall of the end cover is provided with a flange structure accommodated in the flange hole; a filter element cover having a T-shaped water inlet channel communicated with the first water inlet cavity and a water outlet channel communicated with the first water outlet cavity; a filter element having a water purification cavity communicated with the water outlet channel; and a casing fixed on the end cover, a fourth water inlet cavity is provided between the casing and the filter element and communicated with the T-shaped water inlet channel.

Abstract: Exemplary embodiments of a filter cartridge for a coffee machine are disclosed. According to one exemplary embodiment, a coffee machine filter cartridge may include a filter body having a water inlet, a grate and a water outlet, and a lid held on the filter body. The water inlet is disposed around the water outlet. The water outlet connects to one end of the grate through a pipe. The other end of the grate is held on the inner wall of the filter body and comprises a cloth filter. A filter chamber between the pipe and the filter body has a descaling core. When filtering and descaling, the water flows sequentially through the water inlet, filter chamber, grate, cloth filter, pipe, and water outlet. The cartridge is structurally simple, convenient and accessible to users; preventing clogging of the internal parts of the coffee machine by slow dissolution of the descaling agent.

Abstract: A water filtration system is provided. The system may include a connector and a filter configured to be mounted in the connector. The connector may include a connector body, a connector inner core, a connector core baffle, a connector body water inlet of the connector body, and a connector body water outlet of the connector body. The water filtration system may have a filtering configuration and a bypass configuration. In the filtering configuration, the water filtration system may be configured to direct water through the filter. In the bypass configuration, the water filtration system may be configured to direct water out the connector body water outlet without passage through the filter. The water filtration system may be in the filtering configuration when the filter is fully mounted in the connector. The water filtration system may be in the bypass configuration when the filter is not fully mounted in the connector.

Abstract: The Invention relates to a single-stage filtration system, including a joint and a filter element, wherein the joint is mounted on the filter element, a joint body is provided thereon with a water inlet cavity I and a water outlet cavity, one end of the water inlet cavity is a water inlet joint, the water inlet joint is provided thereon with a water inlet boss, the water inlet boss is cylindrical, a water inlet hole is at the center of the water inlet boss, one end of the water outlet cavity is connected with the water outlet joint, the water outlet cavity is located at an eccentricity of the water outlet boss, one end of the water outlet cavity is connected with the water outlet joint, and the other end of the water outlet cavity is on the water outlet boss. The Invention improves the wear of a connector caused by the repeated disassembly of a filter through the setting of the single-stage filtration system, and ensures the sealing performance of the filtration system.

Abstract: The Invention relates to a novel single-stage filtration system, including a joint and a filter element, wherein the joint is mounted on the filter element, the joint includes a joint body, a water inlet sealing ring, a water inlet cover plate and a water inlet clamp, a water outlet sealing ring, a water outlet cover plate and a water outlet clamp, the joint body includes a water inlet cavity, a water outlet cavity, a water inlet joint, a water outlet joint, a connecting flange, a water inlet sealing cavity, a water outlet sealing cavity, a hanging piece and a reinforcing rib, the water inlet cavity of the joint body is an L-shaped cylindrical cavity, one end of the water inlet cavity is connected with the water inlet joint, and the other end of the water inlet cavity is in the water inlet sealing cavity, the water outlet cavity is a circular cylindrical cavity.

Abstract: The invention provides a filtration system with a rotating core driving thimble opening and closing water passage, comprising a casing, a filter and a connector, wherein the filter and the connector are connected and fixed in an inner cavity of the casing, the casing consists of an upper cover of the casing and a lower cover of the casing, which are connected via a connecting member; a connector core of the present invention has a groove and a boss thereon, the connector core, a water intake thimble and a water outtake thimble are tightly pressed by a spring, when the connector is rotated, the water intake thimble and the water outtake thimbles are raised from the position of the groove to the position of the boss, and the water passage is opened. When disassembled, the connector is lowered from the position of the boss to the position of the groove, and the water passage is closed, preventing the leakage of the connector water due to the removal of a filter element.
