Technical field

The utility model relates to a kind of water treatment plant, particularly a kind of water treatment plant that is used to be installed in tap, has two filter cartridge constructions.

Background technology

General tap connects the running water that draws and contains impurity such as fine sand, bacterium, algae, heavy metal, inorganic matter.If untreated or filtration supervisor then easily because of the unclean water of long-term drinking, and causes harmful effect to the health of human body.

Therefore, developed a kind of water treatment plant, it mainly comprises housing, filter core and adapter, described housing has water inlet and delivery port, and its inside is formed with the cavity volume of hollow, and described filter core is installed with the described cavity volume inside at described housing, and adapter then is connected on the water inlet of housing.End with adapter during use is connected in the outlet of tap, the water that the connects the diversion tap described water treatment plant of can flowing through earlier, and filter aforesaid impurity by its filter core, drink and make the user can obtain clean and safe water.

Yet, though known water treatment plant has the effect of impurity screening, but still have following problems: because the filtering material of filter core inside is running stores basic the use, and current are when pipeline is delivered in the family, can be entrained with on the way that the pipeline inner edge peels off or the fine sand of water head site etc. than the impurity of macroparticle, though can be subjected to the filtration of filtering material, but the deposition of too many big molecular impurity can cause the filtering material of filter core inside can not re-use soon, thereby significantly reduced the service time of filter core, and filtering material is the core of water treatment plant, it also is one of the most expensive consumptive material, therefore how prolonging the service time of filtering material, then is the most important problem that the utility model will be studied.

The utility model content

A purpose of the present utility model is, a kind of water treatment plant with two filter cartridge constructions is provided, and it can be by the filtration in advance of second filter core than the impurity of macroparticle by the separation setting of each filter core, effectively reduce the deposition of the macroparticle on first filter core, and then prolong the service time of first filter core.

Another purpose of the present utility model is, a kind of water treatment plant with two filter cartridge constructions is provided, it utilizes the differing heights setting of each filter core, and second filter core repeatedly is connected on first filter core top, after using a period of time, can change second filter core, and then significantly reduce whole use cost.

In order to achieve the above object, the utility model provides a kind of water treatment plant with two filter cartridge constructions, in the outlet that is installed in tap; Described water treatment plant comprises housing, first filter core and second filter core, wherein said housing comprises base and is connected in the cover cap of described base, be formed with the cavity volume of hollow in described cover cap and base inside, on described base, be formed with the water inlet and the delivery port that communicate with described cavity volume; Described first filter core comprises body, involution is at two lids of described body both sides and first filtering material that fills in described body inside respectively, on each described lid, be respectively equipped with a plurality of perforation, one end of described first filter core is contained in described base inside, and the other end then extends into described cover cap inside; The height of described second filter core is less than the height of described first filter core, and described second filter core repeatedly is connected on described first filter core, and is located in the cover cap inside of described housing.

Compared with prior art, the beneficial effects of the utility model are, by adopting the structure setting of two filter cores, can make current be subjected to the filtration of different filtering materials successively, and progressively remove impurity of different nature, further increase its filtration and cleaning effect to water; In addition, because the second filter core height repeatedly connects setting mutually less than the first filter core height and the two, therefore after using a period of time, can change, thereby significantly reduce whole use cost second filter core.
