Portable water purifier

Abstract

The invention relates to a portable water purifier, comprising a machine shell, a filtering and purifying device and a bailing device; the invention is characterized in that: the bailing device comprises a pump body, a membrane, a swing body, a speed-increasing box, an eccentric wheel and a rocking handle; the pump body and the machine shell are fixed relatively, an upper concave part of a water inlet pore is opened on the pump body, the upper concave part is internally fixed with flexible septulum, water outlet pores are opened on the pump body, and the lower end face of the pump body is fixed with flexible macromesenterium; the membrane is fixed at the upper part of the pump body, the middle of the membrane is provided with a flexibly movable part which can telescope and deform relative to the upper concave part; the swing body is arranged at the upper part of the membrane and can swing relative to the machine shell, the lower part of the swing body is provided with a swing head fixed with the flexibly movable part; the speed-increasing box is fixed at the upper part of the machine shell, an input shaft of the speed-increasing box is connected with the rocking handle, an output shaft thereof is connected with the eccentric wheel, and the eccentric wheel is arranged in a concave cavity of the upper part of the swing body by a bearing. The water purifier can bail by rocking the rocking handle, thus ensuring the operation to be more convenient with the labor saved.

Description

technical field [0001] The invention relates to a water purifier, in particular to a portable water purifier suitable for field use. Background technique [0002] Common household water purification devices all have the disadvantages of being relatively large and inconvenient to carry. Aiming at the defects of ordinary household water purifiers, some people have invented various portable water purifiers that are easy to carry. If it is low, it will take a long time for the water to pass through the ultrafiltration filter device, making the whole filtration process slow and affecting the filtration efficiency. For this reason, someone invented a portable water purifier that increases the filtration pressure, such as a patent No. ZL200620014406.6 (The announcement number is CN200948411Y) Chinese utility model patent "desktop pressurized high-purity water purifier" has just disclosed such a kind of pressurized water purifier, comprises: machine base, water storage tank and cle...

Problems solved by technology

[0004] There are the following disadvantages in pressurizing and pumping water similar to the method of pumping air with an inflator. ①. During operation, the piston rod needs to be pushed up and down to drive the piston to reciprocate. The action stroke is large and the operation is inconvenient; ②. In order to increase the filtration speed, it is necessary to quickly reciprocate the movement of the piston, so the operation is quite laborious. Generally, users with poor physical strength cannot quickly reciprocate the movement of the piston, so the filtration speed is still slow, which cannot satisfy people's high efficiency for outdoor portable water purifiers. filtering needs

[0005] In addition, looking at the existing portable water purifiers, most of them have low filtration clarity and peculiar smell, especially the water purifiers that simply use activated carbon adsorption and iodine resin to kill bacteria cannot effectively remove toxic and harmful substances in outdoor water sources. Moreover, iodine is easy to pollute water, and the taste of water is even worse.
