The invention discloses an outdoor convenient
ultrafiltration water purifier, and relates to the field of water purifiers, the outdoor convenient
ultrafiltration water purifier comprises a shell, a first cavity and a second cavity are arranged in the shell, a
piston is arranged in the first cavity, a water inlet communicated with the first cavity is formed in the side wall of the shell, and the outdoor convenient
ultrafiltration water purifier further comprises a first one-way valve, a second one-way valve and a water outlet, the filter screen ring is arranged in the shell and rotatably arranged around the first cavity, and a part of the filter screen ring is arranged between the water inlet and the first one-way valve in a spaced mode; and the linkage
assembly is used for linking the filter screen ring to rotate when the
piston descends in the first cavity. When the
piston descends to drain water, the first one-way valve limits the water inlet not to pass through
water flow, and meanwhile, the linkage
assembly links the filter screen ring to rotate so as to switch the other part of the filter screen ring to be blocked between the first one-way valve and the water inlet for next water absorption, so that the filtering function is ensured, and the problem of easy blockage is also avoided.
