Abstract
The utility model relates to a tap water filter. An upper cover with a purified water outlet and an air valve is fixed to a casing with a water inlet and a water outlet through a partition plate; a millipore filtration pipe is arranged in the inner cavity of the casing; spiral laminas are arranged between the casing and the millipore filtration pipe; dust on the pipe wall of the millipore filtration pipe can be removed by making use of compressed air; the cleaning can be carried out without disassembly; the utility model can respectively supply the drinking water and washing water.
Description
The utility model relates to a kind of tap water filter device, especially can supply drinking water simultaneously and the household water filter of water for cleaning.
At present, a kind of household water filter is arranged, its structure is: the loam cake that pure water inlet is installed fixes by division board and the cylindrical housings that is provided with the inlet opening, microfiltration tube places the inner chamber of housing, its microfiltration tube is often blocked because of the dust that adheres in the water, cause it to lose filtration, need in time to clean, use inconvenient.
The purpose of this utility model provides a kind of household water filter, and it not only can provide drinking-water, and water for cleaning can be provided.
The purpose of this utility model is achieved in that the loam cake that pure water inlet and valve are installed fixes by division board and the cylindrical housings that is provided with inlet opening and delivery port, inner edge at housing is provided with spiral vane, microfiltration tube places the inner chamber of helical blade, form guiding gutter between spiral vane and housing and the microfiltration tube, running water can be flowed along guiding gutter, wherein a part of running water is cleaned through microfiltration tube, by on the pure water inlet that covers flow out, edible, a part of in addition running water, wash away along the adsorbate of guiding gutter the microfiltration tube circumferential surface, flow out by the delivery port on the housing, use for cleaning, when the micropore on the microfiltration tube is stopped up by dirt, available compressed air is squeezed into the inner chamber of loam cake by valve, again through the inner chamber of microfiltration tube and the micropore on the microfiltration tube, carry out the blowback slag dumping, attachment on the microfiltration tube is blown off, washed away by the flowing water in the guiding gutter, to reach the purpose of cleaning microfiltration tube, can make microfiltration tube obtain regeneration, recycling.
Owing to adopt such scheme, can improve filter effect, it can be divided into running water drinkable water and water for cleaning, can utilize compressed air to carry out blowback to remove dust and the impurity on the micro porous filtration tube wall, do not need disassembly, cleaning, can recover the filtration of microfiltration tube, but and using water wisely.
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a structural map of the present utility model.
Among the figure 1, housing 2, microfiltration tube 3, spiral vane
4, inlet opening 5, loam cake 6, division board
7, pure water inlet 8, valve 9, delivery port
In the embodiment shown in fig. 1, the loam cake (5) of pure water inlet (7) and valve (8) is installed, fix by division board (6) and the housing (1) that is provided with inlet opening (4) and delivery port (9), microfiltration tube (2) places the inner chamber of housing (1), its delivery port communicates with the inner chamber of loam cake, spiral vane (3) can constitute one with the inner edge of microfiltration tube (2), also spiral vane (3) can be made one separately, go up an installation valve (8) at loam cake (5), its structure is with the valve inside valve.Operation principle is: at first delivery port (9) is closed, water inlet (4) is connected, running water successively through the inner chamber of the inner chamber of inlet opening (4), housing (1), spiral vane (3), microfiltration tube (2) to pure water inlet (7), edible, wherein another path is to delivery port (9), for cleaning usefulness through spiral vane (3).
