Description

Technical Field

[0001] This utility model belongs to the field of water storage tank structure, specifically relating to a reverse osmosis water purification pressure storage tank. Background Technology

[0002] Reverse osmosis water purifiers require a pressurized water storage tank. Currently, these tanks are available in steel and plastic. The plastic tank consists of two injection-molded halves of a tank, plus a rubber bladder, all ultrasonically welded together to form an inseparable unit. The rubber bladder divides the tank into a water chamber and an air chamber. Compressed air is injected into the air chamber. Due to the compressibility of air, the water chamber expands while the air chamber decreases under pressure. When water is needed, the air pressure forces water out of the tank. This structure, with the rubber bladder welded to the tank body, cannot be replaced. Furthermore, long-term use of the water chamber can easily lead to secondary contamination, which is detrimental to safe drinking water. Also, the welded joints of the injection-molded tank are prone to bursting under internal pressure, posing a safety hazard. Summary of the Invention
