Description
Technical Field
[0001] The utility model relates to the technical field of water treatment equipment, in particular to a quick filter element replacement device for a spring water direct drinking machine. Background Art
[0002] A direct drinking machine is an appliance that purifies municipal tap water into direct drinking water, and at the same time heats, cools and distributes the purified water by consuming electrical energy. A direct drinking machine is a water purification machine that filters and purifies municipal raw water to produce direct drinking water for people. It is also called terminal water purification equipment. It mainly removes pollutants in the water through filter elements, such as rust, colloids, odors and bad smells, and produces water that can be directly drunk.
[0003] A filtering device for a direct drinking machine disclosed in Chinese patent CN219815564U includes a filter cartridge and a filter element arranged in the filter cartridge, wherein the two ends of the filter cartridge are respectively provided with a first end cap and a second end cap, wherein the first end cap and the second end cap are provided with a plurality of mounting grooves, wherein a clamping plate is rotatably provided in the mounting groove, and both sides of the outside of the filter cartridge are fixedly connected with fixing rings, wherein the fixing rings are provided with a plurality of sockets, and a limiting rod is rotatably provided on the outside of the clamping plate. This patent enables the first end cap and the second end cap to be quickly disassembled and assembled at the ends of the filter cartridge by providing the clamping plate, without the need for tools to operate, and the stability of the clamping member can be ensured by plugging and installing the limiting rod and the socket.
[0004] However, while solving the problem, this patent also requires the installation of magnets to block and support the limit rod, and the installation and disassembly are relatively complicated. The magnetic force of the magnet may be affected by environmental factors such as temperature and humidity, resulting in weakened or unstable magnetic force. If the magnetic force of the magnet is not enough to stably block the limit rod, then under the action of vibration or external force, the limit rod may accidentally fall off, thereby affecting the stability of the entire device.
