Referring to fig. 1, in the present embodiment, a composite filter element assembly 1 is provided, which includes at least two filter elements stacked one on another. In this embodiment, the composite cartridge assembly 1 comprises two cartridges stacked. Thus, as shown in fig. 1, in the present embodiment, the composite filter element assembly 1 comprises: a filter flask 20, an end cap 40, a first filter element 60, and a second filter element 80. Since the composite filter element assembly 1 of the present embodiment includes the first filter element 60 and the second filter element 80 which are stacked, in the present embodiment, the composite filter element assembly 1 includes two raw water inlets and two purified water outlets, which correspond to and are fluidly connected to the first filter element 60 and the second filter element 80, respectively.
Hereinafter, the filter flask 20 of the present embodiment will be described in detail with reference to fig. 2 and 3. Wherein the arrows in figure 3 represent the direction of the water flow.
As shown in fig. 2 and 3, the filter flask 20 has an interior chamber 210, and the interior chamber 210 is configured to receive the stacked first and second cartridges 60, 80. As shown in fig. 3, the filter flask 20 is formed with a first raw water inlet 232, a second raw water inlet 234, a first purified water outlet 236 and a second purified water outlet 238. Accordingly, the inner chamber 210 is formed with a first raw water path 212 corresponding to the first raw water inlet 232, a second raw water path 214 corresponding to the second raw water inlet 234, a first purified water path 216 corresponding to the first purified water outlet 236, and a second purified water path 218 corresponding to the second purified water outlet 238. That is, in the composite filter element assembly 1 of the present embodiment, simultaneous filtration can be achieved through a plurality of raw water inlets (232, 234) and a plurality of purified water outlets (236, 238).
As shown in fig. 2 and 3, the bottom of the filter flask 20 is open and a sealing assembly 250 is provided to seal the filter flask 20. Preferably, the sealing assembly 250 is removable to open and close the bottom opening.
Hereinafter, the assembly structure of the stacked filter cartridges will be described in detail with reference to fig. 3 and 4. Wherein the arrows in fig. 3 and 4 represent the water flow direction.
Referring to fig. 4, fig. 4 is a schematic view of an assembly of the end cap 40, the first filter element 60 and the second filter element. As shown in fig. 4, the end cap 40 has an inner space 410, and the inner space 410 is matched with the first filter element 60 for receiving the first filter element 60.
The first filter element 60 has a configuration known in the art, for example, the first filter element 60 has a filter element inlet 610, a filter element outlet 630, a filter element housing 650, and a first filter 670 disposed within the filter element housing 650. The raw water flows into the filter element housing 650 through the filter material after passing through the filter inlet 610, and the purified water flows out of the first filter element 60 through the filter element outlet 630 having a central axis.
As shown in fig. 3 and 4, the first filter element 60 is fluidly connected to the first raw water inlet 232 and the first purified water outlet 236. Of course, for sealing purposes, it will be understood by those skilled in the art that sealing contact between the cartridge outlet 630 of the first cartridge 60 and the first purified water circuit 216 may be achieved, such as by providing a sealing ring therebetween. Such connection and sealing means are conventional structures known in the art and will not be described herein.
As shown in fig. 4, the second filter element 80 is disposed below the first filter element with their central axes coincident, thereby defining a stack of the first filter element 60 and the second filter element.
As shown in fig. 4, the second filter element 80 also has a structure known in the art, for example, the second filter element 80 has an upper end cap 810, a lower end cap 830, and a filter 850 disposed between the upper end cap 810 and the lower end cap 830. In this embodiment, the upper end cap 810 acts as a spacer. As shown in fig. 4, the upper end cap 810 is in contact with the first filter element 60, and a portion of the upper end cap 810 enters the interior space 410 of the end cap 40, such that the upper end cap 810 and the end cap 40 form an enclosed space. For sealing purposes, it will be understood by those skilled in the art that a sealing ring 812 is disposed between the upper end cap 810 and the surface of the interior space 410 such that a sealed interior waterway 814 is formed between the interior space 410 of the end cap 40 and the cartridge housing 650 of the first cartridge 60 by the upper end cap 810 of the second cartridge 80.
As shown in fig. 3 and 4, a gap 220 is formed between an outer circumferential surface of the end cap 40 and a surface of the inner chamber 210, the second raw water inlet 234 is fluidly connected to the gap 220 through the second raw water path 214, and the second purified water outlet 238 is fluidly connected to the inner water path 814 through the second purified water path 218. In addition, as shown in fig. 3 and 4, the filter material 850 of the second filter element 80 is at least partially exposed to the interior of the filter bottle. That is, at least a portion of the outer surface of the filter medium 850 of the second filter element 80 is directly exposed to the inner cavity 210 of the filter bottle 20, so that the raw water introduced from the second raw water inlet 234 passes through the second raw water path 214 and the gap 220 and then directly passes through the filter medium 850 to complete the filtration, as shown in fig. 4. Then, the filtered purified water flows out from the second purified water outlet 238 through the internal water path 814 and the second purified water path 218, thereby completing the filtering process of the second filter element 80.
Therefore, in the composite filter element assembly 1 of the present invention, the end cover 40 is disposed at the position of the first filter element 60 and the second filter element 80, so that the first filter element 60 and the second filter element 80 respectively have mutually independent filtering water paths, and the first filter element 60 and the second filter element 80 can be synchronously and independently filtered.
Of course, those skilled in the art can understand that, in the present invention, 3 stacked filter elements may be disposed in the filter bottle 20, and of course, a raw water inlet and a purified water outlet may also be correspondingly added, and the structure is similar to the above-mentioned embodiment, and will not be described herein again.
Compound filter element group spare pass through the position setting between end cover and the filter core for each filter core has mutually independent filtration water route, can realize the synchronous independent filtration of a plurality of filter cores.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
