Referring to fig. 1, the household water filtering device easy to replace according to an embodiment of the present utility model includes an outer tub 100, the outer tub 100 having a first end and a second end, a water inlet 110 being provided on a sidewall of the first end of the outer tub 100, the second end being sealed, a top cover 120 being provided on an end cover of the first end of the outer tub 100, and a water outlet 121 being provided on the top cover 120;
the inner cylinder 200 is coaxially arranged in the outer cylinder 100, a space is reserved between the outer wall of the inner cylinder 200 and the inner wall of the outer cylinder 100, a supporting component 300 is arranged between the inner cylinder 200 and the bottom of the second end of the outer cylinder 100, the inner cylinder 200 is in abutting connection with the surface of the top cover 120 to form a seal, and the filter material 400 is filled in the inner cylinder 200;
wherein, the outer cylinder 100 and the inner cylinder 200 together form a flow channel, and the path of the flow channel sequentially comprises a water inlet 110, a space between the outer wall of the inner cylinder 200 and the inner wall of the outer cylinder 100, the inside of the inner cylinder 200 and a water outlet 121.
The water inlet 110, the space between the outer wall of the inner cylinder 200 and the inner wall of the outer cylinder 100, the inner space of the inner cylinder 200, and the water outlet 121 together constitute a flow path of water flow. When filtering water, pressurized water enters from the water inlet 110, flows from the space between the outer wall of the inner cylinder 200 and the inner wall of the outer cylinder 100 to the end of the inner cylinder 200, and then enters the inside of the inner cylinder 200. When the water flows through the inner space of the inner cylinder 200, the filled filter material 400 filters the water to obtain purer water, and the filtered water flows to the top cover 120 and then flows out of the water outlet 121.
When the filter material 400 needs to be replaced for a long period of time, the filter material 400 in the inner barrel 200 can be poured and then refilled by only opening the top cover 120 and taking the inner barrel 200 out of the outer barrel 100, and the whole water filtering device does not need to be disassembled. And after the filter material 400 is replaced, the inner cylinder 200 is replaced in the outer cylinder 100, the top cover 120 is closed to be reused, the process of replacing the filter material 400 is simple, and the consumed time is short.
Referring to fig. 2, it can be understood that the support assembly 300 includes a first ring 310, a second ring 320, and a plurality of struts 330, the diameter of the first ring 310 is greater than that of the second ring 320, the first ring 310 is disposed at the bottom of the second end of the outer cylinder 100, the second ring 320 is disposed coaxially with the first ring 310, the second ring 320 is not in the same plane with the first ring 310, the first ring 310 and the second ring 320 are connected by the plurality of struts 330, and the struts 330 are uniformly distributed along the circumferential direction, so that the first ring 310, the second ring 320, and the plurality of struts 330 together form a circular truncated cone structure, and the end of the inner cylinder 200 is abutted on the struts 330.
The diameter of the first ring 310 is larger than the diameter of the second ring 320 so that the first ring 310 can be fitted with the inner diameter of the outer cylinder 100 and the second ring 320 can be fitted with the inner diameter of the inner cylinder 200. When the inner barrel 200 is placed on the support assembly 300, the second ring 320 can extend into the interior of the inner barrel 200 such that the sidewall end surfaces of the inner barrel 200 can contact the struts 330 to support the inner barrel 200. When the water flows from the space between the outer wall of the inner tube 200 and the inner wall of the outer tube 100, the water flows into the inner side of the inner tube 200 through the space between the struts 330.
It will be appreciated that the filter 400 comprises a plurality of filter layers, and that the filter layers are arranged in an axial direction of the inner cartridge 200, with the porosity of the different filter layers progressively decreasing in a direction closer to the water outlet 121.
The multiple filter material layers can gradually filter impurities with different sizes in the water flow so as to improve the filtering effect. For example, when a single filter material layer is used, the porosity is generally set smaller for better final water quality, so that the front end of the water flow is easy to be blocked, the service time of the filter material 400 is short, and the water pressure loss is larger. After being divided into a plurality of filter layers, impurities with different sizes can be filtered out in the filter layers with different porosities, and the using time of the filter 400 is prolonged. The porosity refers to the percentage of the void volume to the total volume in a certain volume, namely, the lower the porosity is, the smaller the size of impurities capable of being filtered is, and the better the filtering effect is.
It will be appreciated that filter 400 comprises a first filter material filled in the interior of inner barrel 200 and located on a side of inner barrel 200 remote from top cap 120, a second filter material filled in the interior of inner barrel 200 and located on a side of inner barrel 200 near top cap 120, and a third filter material filled between the first filter material and the third filter material, the porosity of the first filter material, the second filter material, and the third filter material gradually decreasing.
The water flow first reaches the side of the inner barrel 200 remote from the top cover 120, i.e., the side where the support assembly 300 is located. The water flow enters the inner cylinder 200 through the support assembly 300, first contacts the first filter material for preliminary filtration, then performs fine filtration at the second filter material, and finally performs ultra-fine filtration at the third filter material.
It is understood that, preferably, the filter plates 500 are respectively disposed between the first filter material and the second filter material, between the second filter material and the third filter material, and between the third filter material and the top cover 120, the plate surface of the filter plates 500 has a plurality of first filter holes, and the diameters of the first filter holes on the filter plates 500 are smaller than the particle diameters of the filter materials 400. The filter plate 500 is able to avoid particle streaming between different filter material layers.
Referring to fig. 3, it can be understood that the inner cylinder 200 is provided with a coarse filter cartridge 210, a fine filter cartridge 220 and a super fine filter cartridge 230, one ends of the coarse filter cartridge 210, the fine filter cartridge 220 and the super fine filter cartridge 230 are all opened, the other ends are all provided with a bottom plate, a plurality of second filter holes are arranged on the bottom plate, the coarse filter cartridge 210 is positioned at one end of the inner cylinder 200 far from the top cover 120, the super fine filter cartridge 230 is positioned at one end of the inner cylinder 200 near the top cover 120, the fine filter cartridge 220 is positioned between the coarse filter cartridge 210 and the super fine filter cartridge 230, the first filter material is filled in the coarse filter cartridge 210, the second filter material is filled in the fine filter cartridge 220, and the third filter material is filled in the super fine filter cartridge 230.
When the filter material 400 is replaced, the coarse filter cartridge 210, the fine filter cartridge 220 and the ultra-fine filter cartridge 230 are taken out respectively, and the first filter material, the second filter material and the third filter material can be poured simultaneously and filled simultaneously, and only the coarse filter cartridge 210, the fine filter cartridge 220 and the ultra-fine filter cartridge 230 need to be put back to the inner cylinder 200 in sequence finally. The synchronous operation can shorten the replacement time of the filter material 400 without the need to fill the first filter material, the second filter material, and the third filter material back into the inner tub 200 layer by layer.
It will be appreciated that the open end of the ultrafiltration cartridge 230 is covered with a cover plate 240, and the cover plate 240 is provided with a plurality of third filter holes.
The cover plate 240 is disposed to cover the open end of the ultrafiltration cartridge 230, thereby preventing the third filter material from escaping from the ultrafiltration cartridge 230. Typically, both the outer cartridge 100 and the inner cartridge 200 are vertically placed, and the third filter material does not escape from the open end of the superfinishing cartridge 230 under the force of gravity, but the installation posture of the outer cartridge 100 and the inner cartridge 200 is limited. In certain circumstances, the outer cartridge 100 and the inner cartridge 200 need to be disposed obliquely, so that the cover plate 240 can effectively avoid the escape of the third filter material.
Referring to fig. 4, it can be understood that an outer rim 250 is provided at an end of the inner tube 200 abutting against the top cover 120, the outer rim 250 extends outward in a radial direction of the inner tube 200, and an elastic spacer 260 is further provided between the outer rim 250 and the top cover 120.
The contact area between the outer edge 250 and the top cover 120 can be increased, and after the elastic gasket 260 is provided, the pressing force of the contact surface can be adjusted more easily, so as to obtain a better sealing effect, and prevent water flow from directly flowing from the water inlet 110 to the water outlet 121.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
