Embodiment 1
[0025] Such as figure 1 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a filter includes a filter body 6, and the filter body 6 is composed of a connecting part 1, a bottle body 2, a filter cartridge 3, a sewage valve 4, and a polymetallic water treatment filter material 5.
[0026] The bottom end of the connecting part 1 is provided with two concentric bottle interface 10 and filter cartridge interface 11, and the top of the connecting part 1 is provided with an installation opening 12, and a rotation control rod 13 is arranged in the installation opening 12. The outer end of the rotation control rod 13 is fixedly connected with a hand wheel 14 , and its inner end stretches toward the bottom of the filter cartridge 3 , and the rotation control rod 13 is provided with a plurality of stirring paddles 17 .
[0027] The upper end of the bottle body 2 and the bottle body interface 10 are fixed by threaded connection; the filter...
Embodiment 2
[0035] Such as figure 2 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, an electric actuator 7 is fixedly connected to the outer end of the rotation control rod 13 .
[0036] Others are the same as in Embodiment 1, and will not be repeated here.
Embodiment 3
[0038] Such as image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a composite pre-filter includes a pre-filter 8 and the filter body 6, which is characterized in that the pre-filter 8 and the filter body 6 are connected in series side by side in sequence, i.e. The pre-filter 8 is provided with the same connecting portion 1 as the filter body 6, and the two connecting portions 1 are integrated, wherein the water outlet of the pre-filter 8 is connected to the water inlet of the filter body 6 and as one.
[0039] In this embodiment, the detailed structure of the filter body 6 is the same as that in Embodiment 1, and will not be repeated here.

Abstract
A traditional prefilter in the current marker can generally and roughly filter impurities singly but cannot filter heavy metal elements which have great maximum hazard to a human body and are invisible as well as residual chloride in water. In view of the problems of the prefilters with various types, the invention provides a filter and a composite prefilter, and provides a brand new technology ofthe prefilter for solving the technical problems; and a water treatmentfilter material, in particular to a KDF multi-metalwater treatmentfilter material, is applied to the prefilter, so that the composite prefilter can remove impurities, 90 percent or above of residual chloride and heavy metal elements in the water.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a filter and a composite pre-filter technology. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people began to have higher requirements for water and dietary health in daily life. Due to secondary pollution such as rust and sediment in the water supply of the city, the water quality of household water deteriorates and the control of water equipment fails, and the life of other household appliances involving water is shortened, and even a huge safety hazard is generated. Therefore, From the perspective of the general environment, every household needs to install a pre-filter to improve water quality and protect household water equipment. The pre-filter is the nemesis of secondary pollution and a reliable impurity filtering device. [0003] At present, the pre-filters in the market can only si...
