Description

A kind of washing machine water strainer

Technical field

The utility model relates to the washing machine water strainer of the water strainer that is used for water conditioning, particularly a kind of conveniently replaced filter core.

Background technology

At present, in China many places, particularly large-and-medium size cities; since densely populated, the environment protection deficiency, and severe contamination is suffered in the location, water source for a long time; the corrosion of running water pipe is arranged again, and the roof water tank does not in time clean, and all directly influences the quality of resident's daily life water.To this, people take corresponding way, after adopting methods such as water purifier and water-purifying machine that water is carried out corresponding filtration, purification processing, as Drinking Water, but for the water of washing clothes of daily life because condition restriction, generally not making filtration, purification handles, though, the inlet end of existing washing machine all is provided with the layer of metal filtering net, the impurity of larger particles in the energy filtering water, but can't filter out the tiny iron rust in the water, silt, heavy metal ion etc. are to washing machine and the prejudicial impurity of clothes, the chemicals and the carcinogenic substance that exist in more can't filtering water, and these materials the easiest garment surface that rests on after clothes is washed by human body skin is absorbed, influences the health of people's health.

The utility model content

The purpose of this utility model is the problem that exists at prior art and provide a kind of simple in structure, easy accessibility, cost low, is applicable to the supporting use of washing machine, and the water strainer of conveniently replaced filter core.

The technical scheme in the invention for solving the above technical problem is: a kind of washing machine water strainer, comprise upper housing, filter core, lower housing, and upper housing and lower housing are threaded mutually, in the groove of connection section bottom the housing seal circle are housed; Upper end at upper housing is provided with male connection, and its center has through hole and is communicated with the housing inner chamber, is provided with female adapter in the lower end of lower housing, and the joint endoporus is communicated with the housing inner chamber; Described filter core is arranged in upper housing and the lower housing hollow cavity that the back forms that is threaded mutually, it is characterized in that filter core comprises the cotton filter core of crossing of the molten spray of the multilayer that is tubular structure PP, glued joint at its two ends last set casing and following set casing, between the cotton splicing face of crossing filter core of following set casing and PP, go back liner and glued joint the non-woven fabrics interlayer is arranged, be filled with gac in the hollow cavity above the interlayer; Be provided with a socket cap that has a through hole in following set casing lower end, it is connected with the through hole top of female adapter on the lower housing, and socket cap cylindrical joint face is provided with groove, is embedded with two filter core sealing-rings in the groove.

The joint sealing circle is equipped with at the omoplate place of the screw thread bottom endoporus of described female adapter.

Water strainer of the present utility model is in the supporting use with washing machine, because filter core is designed to an one-piece construction, its connection with body skin is fixing by the elasticity close-fitting joint of filter core sealing-ring, so, clean and more during renew cartridge, as long as open lower housing, from lower housing, extract filter core or plug filter core and get final product, and convenient; Simultaneously, can be spirally connected with washing machine inflow port and water inlet pipe polyphone easily in use; And, the outer multilayer PP cotton fibre that adopts of filter core is crossed filter core, and internal layer adopts gac, and both combinations are the filtering detrimental impurity such as solids in the water, throw out, colloidal particle of doing washing effectively, and chemicals and carcinogenic substance in the adsorbable removal water, guarantee the cleaning of laundry water.
