Description
Technical field
The utility model relates to a kind of feeding water filtering device for water pump.
Background technology
Water pump often can suck hairs a large amount of in the water, bathing foreign material or other floating things simultaneously when the recirculated water that extraction bathing pool, swimming pool etc. are located.Therefore, need to be installed into water filtering device between drinking-water pipe and the water pump, it comprises housing, is suspended at filter core and the removable top cover that is installed on the housing in the housing, the top of housing is provided with water inlet, the bottom of housing is provided with delivery port, water inlet is connected with drinking-water pipe, and delivery port is connected with water pump, is evenly distributed with several filter openings on the filter core.Water is being carried a large amount of foreign material secretly and is being entered in the filter core by water inlet, water passes filter opening and flows into delivery port, in the arrival water pump, foreign material can't pass filter opening and stay in the filter core, realize the isolated by filtration function of foreign material, avoiding foreign material to stop up the water inlet of water pump, or be wrapped on the impeller after entering water pump, affect its running.
Laterally be provided with a cross bar in the housing of existing feeding water filtering device for water pump, cross bar is provided with connecting rod down, and the lower end of connecting rod is connected with filter core, realizes filter core suspending in housing with this.This mounting structure is very complicated, and filter core also easily rocks in housing during use, and the placement of filter core is not steady, and filter core and housing all damage because rocking bump easily; And after long-term the use, the foreign material accumulation in the filter core is too much, needs in time cleaning, and the user must pull down first cross bar, brings out filter core by cross bar again, then pulls down connecting rod, could thoroughly clear up filter core, troublesome poeration, cleaning inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and can a kind of filter core suspend simple in structure, steady is provided, and filter core is taken and is used for easily the feeding water filtering device of water pump.
For this reason, the technical solution adopted in the utility model is as follows: a kind of feeding water filtering device for water pump is provided, it comprises housing, be suspended at filter core and the removable top cover that is installed on the housing in the housing, the top of housing is provided with water inlet, the bottom of housing is provided with delivery port, be evenly distributed with several filter openings on the filter core, its technical characterictic is, the inner diameter on the top of described housing is greater than the inner diameter of the bottom of housing, form limited step, the upper end of filter core is provided with the spacing ring that is used with limited step, and the height of the housing parts that limited step is following is greater than the height of filter core; Also be provided with at least one lift-pull handle on the described filter core.
Adopt the feeding water filtering device that is used for water pump of above structure compared with prior art, have the following advantages: the mounting structure of filter core in housing is simple, and filter core directly is placed on the interior limited step of housing, and contact area increases, and places steadily; When needing cleaning, take out filter core by lift-pull handle, easy to operate.
As improvement, described lift-pull handle is two, and is symmetricly set on the filter core.This setting so that when needing the cleaning filter core, can divide indescribably two lift-pull handles with two hands, the user firmly evenly, the taking-up of filter core is more steady.
As improvement, described filter core is that engineering plastics are made.This setting is so that the lighter weight of filter core.
The beneficial effects of the utility model are mainly reflected in: that filter core suspends is simple in structure, filter core is more steady during operation, and it is light to take.
