Title: NATURAL WATER PRESSURE-BASED WATER PURIFICATION BOTTLE
Abstract:
A natural water pressure-based water purification bottle, comprising a body (1) and a cap (2); the body (1) is provided with a filter cartridge (10) at a position close to the cap (2); a recessed cavity (20) is provided inside the cap (2); both the sidewall and the bottom of the recessed cavity (20) are provided with a plurality of water inlets (200) for water inflow; the outer surface of the cap (2) is provided with a metallic hanging loop (21); a metal cord (22) is provided on the hanging loop (21); the outer surface of the body (1) is wrapped with an elastic buffer shell (11). When used, the natural water pressure-based water purification bottle sinks deeply into natural water by means of the metal cord (22), and performs pressure filtration by using natural water pressure, so that a great amount of purified water can be obtained each time, and the number of devices needing to be carried and the load are reduced, thereby improving the filtration efficiency. The size of the water inlets (200) can be changed for primary filtration of large impurities, so as to improve the water purification efficiency. When water purification is not required, the natural water pressure-based water purification bottle can be used as a common water bottle by taking out the filter cartridge (10).
