AI Technical Summary

Technical Problem

Existing water purifier products lack water storage functions, and increasing the pressure resistance of the water storage tank would lead to increased material costs, making existing pressure reduction methods uneconomical.

Method used

It adopts a combination structure of inlet shut-off valve and two-way venting one-way check valve. By controlling the flow of water and air, it achieves pressure balance inside and outside the water storage tank, reduces the pressure inside the water storage tank, and realizes automatic water storage and discharge functions by combining the connection structure of detachable filter cartridge and water storage tank.

Benefits of technology

It achieves automatic water storage without increasing the amount and quality of materials in the water storage tank, reduces the pressure inside the tank, reduces equipment costs, and offers flexible filter element combinations to adapt to different water quality requirements, allowing for rapid water release and protecting the pressure resistance requirements of subsequent water-using equipment.

Abstract

This utility model provides an economical automatic water purification and storage device with a pressure-reducing structure, including a filter cartridge assembly, a water storage tank, a purified water delivery pipe, an inlet shut-off valve, a two-way venting one-way check valve, and a faucet. The filter cartridge assembly and the water storage tank are connected through the purified water delivery pipe. The top of the water storage tank is equipped with an inlet shut-off valve and a two-way venting one-way check valve. A faucet is located on the lower part of the side wall of the water storage tank. The inlet end of the filter cartridge assembly is connected to an external water source pipe, and the outlet end of the filter cartridge assembly is connected to one end of the purified water delivery pipe. The other end of the purified water delivery pipe is connected to the inlet end of the inlet shut-off valve. The beneficial effects of this utility model are: by combining the inlet shut-off valve's positional shut-off with the two-way venting one-way check valve's venting and pressure reduction, the pressure on the tank when increasing water storage is effectively reduced, the pressure resistance requirement of the water storage tank is lowered, the purpose of unattended automatic water storage is achieved, and the cost is reduced. It also improves the anti-freezing and cracking ability, and the combination is flexible and versatile. Each level of filter cartridge can be freely combined and used according to needs to ensure water quality.
