Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.

In describing embodiments of the present invention, the terms "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and other terms are used in an orientation or positional relationship shown in the associated drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Fig. 1 is a structural view schematically showing a filter device according to an embodiment of the present invention. As shown in fig. 1, the filtering device of the present invention includes a housing 1, a middle shaft 2 and a spiral structure 3. The housing 1 is substantially in the form of a lying cylinder provided with an inlet 11 and an outlet 12. The central shaft 2 is a hollow cylinder, and one end of the central shaft is connected to the shell 1 and communicated with the water outlet 12, and the other end of the central shaft is provided with an opening. The utility model discloses in, 2 whole sizes of axis should be shorter than casing 1, and the one end that delivery port 12 was kept away from to axis 2 promptly possesses certain space with casing 1 inner wall to make water can flow in hollow axis 2 from this space. The helical structure 3 is arranged on the middle shaft 2, extends along the length direction of the middle shaft 2 and penetrates through the whole middle shaft 2. The utility model discloses a filter equipment mainly utilizes the active carbon to accomplish and filters, therefore 1 inside packing of casing has graininess filtrations A. In the present embodiment, the filter is activated carbon particles, but other granular adsorbents such as polyacrylamide and zeolite can be used as the filter according to actual needs. And due to the presence of the helical structure 3, these activated carbon particles are located in the interstices between the helices. Therefore, water enters through the water inlet 11, enters the central shaft 2 from the opening at the other end of the central shaft 2 after being filtered by the active carbon, and finally flows out of the filtering device from the water outlet 12. It follows that the water stream, after passing through the activated carbon, inevitably carries with it fine activated carbon powder. In order to prevent the powder from flowing out of the device and affecting subsequent water use, the hollow central shaft 2 can be filled with fiber materials for secondary filtration, so that the activated carbon powder and other substances can be filtered. In the present invention, the fiber material may be polypropylene (pp material) or other materials with this function.

The utility model discloses in, set up helical structure 3's aim at extension water flow distance to realize better water purification effect with shorter active carbon post, save space and raise the efficiency. And the impact of water flow on the activated carbon can be weakened, and the generation of activated carbon fragments is reduced. And for making the flow distance of water longest, the utility model discloses all set up water inlet 11 and delivery port 12 at the same one end of casing 1 (left end in fig. 1 promptly), and axis 2's opening is located the right-hand member this moment, the position farthest away from water inlet 11 promptly. And, the water outlet 12 is located at the center of the left end of the housing 1, so that it can be ensured that the middle shaft 2 and the spiral structure 3 are also located at the center of the housing 1. In addition, in order to further avoid the production of active carbon powder, in the utility model, axis 2 and helical structure 3 all fix the setting, and axis 2 left end fixed connection is in casing 1 left side promptly, and helical structure 3 also fixes the setting on axis 2. Therefore, in the water flowing process, the middle shaft 2 and the spiral structure 3 can not rotate, and the powder generated by friction between activated carbon particles is avoided, so that the blockage is reduced, the water outlet efficiency is improved, and the influence of the activated carbon powder on the subsequent water use is reduced. And the service life of the filter device (filter element) is prolonged to a certain extent by avoiding the pulverization of the activated carbon.

The utility model discloses in, the right side of casing 1 is equipped with detachable lid 13 to be convenient for add the active carbon granule or pour the change with the active carbon in casing 1. The cover 13 and the housing 1 may be connected by a screw or a snap, as long as the cover can be removed. As can be seen from the above, the activated carbon particles added to the casing 1 are finally distributed in the gaps between the individual helices of the helical structure 3. Therefore, activated carbon with different functions or particle sizes can be added into each gap, so that segmented filtration is realized, and the filtration effect is improved. In order to facilitate observation of the adding condition of the activated carbon, the shell 1 can be made of a transparent material, so that the whole shell 1 is transparent, and whether the activated carbon in each gap is filled up or not can be clearly observed. According to the conception, the whole shell 1 can be made opaque, only a transparent observation window is arranged on the shell, and the observation window can extend along the length direction of the shell 1, so that the adding condition of each section of activated carbon can be clearly observed, and the activated carbon is uniformly added.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
