Hand-operated water purifier

Abstract

The invention discloses a hand-operated water purifier, and belongs to the technical field of water purifiers. The hand-operated water purifier comprises a housing, the inner wall of the housing is connected with a support plate, the outer wall of the support plate is connected with a speed change mechanism, a rotating rod is rotatably connected in the housing through a bearing, the rotating rod is connected with the speed change mechanism, one end, far away from the speed change mechanism, of the rotating rod is connected with a rotating disc, and the outer wall of the rotating disc is in threaded connection with a handle. The output end of the speed change mechanism is connected with a pump head body, a water inlet and a water outlet are formed in the outer walls of the two sides of the pump head body respectively, the outer wall of the water inlet is connected with a water drawing pipe, the outer wall of the water drawing pipe is connected with a floating plate, and the end, away from the water inlet, of the water drawing pipe is connected with a U-shaped pipe. The water guide pipe penetrates through the supporting plate and is connected with a filtering device; according to the invention, a water source can be drawn and filtered outdoors, meanwhile, underwater sludge is prevented from being drawn in the process, smooth water drawing is ensured, and the service life of the filter is prolonged.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a hand-operated water purifier. Background technique [0002] In daily life, water is very common and can be easily obtained and used for drinking. However, for those who work in mountainous areas or in the field and at sea, it is necessary to carry out field trips, sea trips and other activities in harsh environments such as fields, deserts, and seas without power supply. For operations, outdoor surveys and explorers, water is very inconvenient to obtain and the water obtained is difficult to reach drinking water standards. [0003] Generally, household water purifiers have a minimum filtration pressure of 10 kg for the RO membrane of the membrane filter element, and a certain water inlet pressure is required during operation to ensure the best filtration effect of the internal filter membrane.

[0002] In daily life, water is very common and can be easily obtained and used for drinking. However, for those who work in mountainous areas or in the field and at sea, it is necessary to carry out field trips, sea trips and other activities in harsh environments such as fields, deserts, and seas without power supply. For operations, outdoor surveys and explorers, water is very inconvenient to obtain and the obtained water is difficult to meet drinking water standards

[0003] Generally, household water purifiers have a minimum filtration pressure of 10 kg for the RO membrane of the membrane filter element, and a certain water inlet pressure is required during operation to ensure the best filtration effect of the internal filter membrane. Generally, through a booster pump Realization, its main working principle is to drive the eccentric rocking wheel at the pump head to move through the rotating motion of the motor rotor. The diaphragm reciprocates along the axial direction, thereby reciprocatingly changing the volume of the water pump. The inlet forms a vacuum to absorb water, and the outlet forms a pressure to continuously discharge water; The suction is not high enough to draw water directly from the surface or underground, and the water cannot be effectively pressurized to the RO membrane for filtration when there is no electricity and energy mechanical power. It cannot satisfy travelers and outdoor workers to drink natural water at any time in the wild. water requirements

[0004] In the prior art, the patent application number CN201320550312.0 discloses "a portable water purifier, including a casing, a hand-operated water pump and a water filter device are installed in the casing, and the hand-operated The water pump includes a crank handle, a reduction box and a pump body that are connected in sequence, and the water inlet of the pump body is connected with a water pipe that extends out of the casing." This utility model can easily draw water in the field and perform deep filtration on the water; But there are still defects, when the water pipe is pumping surface or groundwater, if the water pipe is directly in contact with the bottom of the water, the mud at the bottom of the water will be directly extracted in the process of pumping water, which will block the water pipe, and in the filtration process due to too much sewage The mud is filtered by the filter membrane, which reduces the service life of the filter
