Abstract

The utility model relates to a household water purifier. Wherein, a shell body consists of two parts of a lower shell body with a water intake and a water outlet and an upper shell body covering on the lower shell body, the upper shell body is connected and matched with the lower shell body by a screw thread, a filter core in the shell body comprises a tubular PP filtration membrane and active carbon positioned therein; and a combined two-phase valve for selecting original water and clean water is mounted on the water intake. The utility model can effectively intercept the impurities such as solid matters, flocculate and colloid particles in the water, as well as conveniently dismantling the upper shell body for cleaning the filter core; and the utility model has advantages of small size, convenient use and low cost, and can be directly nested on the water faucet of a common family.

Description

The family expenses water strainer

This reality has novel a kind of treatment device for water that relates to, and particularly is applicable to home-use water strainer.

At present, family expenses water strainer device has two classes, and a class is not to be with the water purifier of back-purge system, and another kind of is the water purifier that has back-purge system; Former structure is simple, but after repeatedly using, the dirt that is deposited on the filter thing needs to clean, folding dress trouble; The latter is not although need demolition to clean filter thing, complex structure, cost height.

It is a kind of simple in structure that the purpose of the utility model is to provide, and the folding dress is convenient, the family expenses water strainer that cost is low.Its technical scheme is such: it mainly is divided into housing brings the lower housing of the mouth of a river, water outlet chewing into and covers upper housing two portions on lower housing, and filter core is by the PP filter membrane that is tubular structure and place the activated carbon fiber in the PP fiter membrance cylinder to constitute; Water-in is positioned at the side of lower housing, and the bottom that is positioned at lower housing relative reactivity carbon fiber filtering layer is chewed in water outlet.Like this, on the one hand can dismantle housing easily, to absorption, be deposited on the intravital filter core of shell and clean; On the other hand, because filter core adopts the PP filter membranous layer and the activated carbon structure of filtering layer of 5 micron pore size, so can hold back impurity such as solids in the water quality, throw out, colloidal particle effectively, and a large amount of chemicals of adsorbable removal with separate all kinds of biologies, carcinogenic substance and smell flavor, reach the purpose of purifying drinking water.

Another purpose of the present utility model is after loading onto this water strainer, still can select to use filtered water or former water easily, it mainly is equipped with built-up type two-phase valve on the technique scheme water-in, this built-up type two-phase valve is made up of two single-phase valves, is provided with raw water inlet, the water supply connector that is connected with water strainer and former water water outlet and chews He Yuanshui, drainage switch handle.When stirring former taps handle, the tap water on the water pipe is directly chewed flowing water from former water water outlet; When stirring the water purification switch handle, outflow is chewed in the water outlet of purifying waste water from water strainer.

Obviously, the utility model uses and to wash or change filter material all quite convenient, and it is little to have a volume, and advantage such as cost is low, and is easy to use can directly be sleeved on the general family water tap.

Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.

Fig. 1 is a kind of example structure synoptic diagram of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Referring to Fig. 1, the family expenses water strainer is by housing and be contained in the intravital filter core of shell and form.Water-in 5b, water outlet chew the lower housing 5 of 5a to housing and the upper housing 1 that covers on lower housing 5 is formed by having, and are threaded between lower housing 5 and the upper housing 1, and rubber seal 8 is equipped with in its junction.Filter core is made of PP filter membrane 3 and activated carbon fiber 4, and PP filter membrane 5 is tubular structure, and is coaxial with the housing medullary ray, and activated carbon fiber 4 places in 5 of the PP filter membranes, and it is plugged with capping plug 2 and following capping plug 6 up and down, and last capping plug 2 employing plastics are made, and are sealed state; Be reticulated structure in the middle of the following capping plug 6, make that the 5a discharge is chewed in the water inflow water outlet in the activated carbon fiber 4.Gapped between PP fiter membrance cylinder outer side wall and the inner walls, the water of water-in enters PP filter membrane 3 through this gap, then, enters water outlet by activated carbon fiber 4 filtrations and chews 5a.

For the utility model in use is allowed a choice, at water-in 5b built-up type two-phase valve 7 is housed, this valve 7 is provided with a water-in 7b, 7c and a water supply connector that is connected with the water strainer water-in and former taps handle 7a, drainage switch handle 7d are chewed in a former water water outlet.Water-in 7b is connected with tap water pipe line.During use, stir former taps handle 7a, drainage switch handle 7d as required.

Claims

1, a kind of family expenses water strainer, by housing, be contained in the intravital filter core of shell and form, it is characterized in that: water-in (5b), water outlet are chewed the lower housing (5) of (5a) to housing and the upper housing (1) that covers on lower housing (5) is formed by having, filter core is by being tubular structure PP filter membrane (3) and placing the activated carbon fiber (4) in it to constitute, and the bottom that (5a) is positioned at lower housing (5) relative reactivity carbon fiber (4) filtering layer is chewed in water outlet.

2, according to the described family expenses water strainer of claim 1, it is characterized in that: gapped between described PP filter membrane (3) and the housing sidewall.
