Detailed Description
In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.
In accordance with one aspect of the present invention, a composite filter element assembly 100 is provided, as shown in fig. 1-4. The composite filter element assembly 100 can be applied to a water purifier. Therefore, according to another aspect of the present invention, there is also provided a water purifier. Water purifiers include, but are not limited to, home water purifiers and central water purifiers, among others. The composite filter element assembly 100 may also be used in any other desired device, if desired. A water purifier and a composite filter element assembly 100 thereof according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 4.
In the illustrated embodiment, the first filter element 200 can be a front filter element. The front filter element comprises but is not limited to a filter screen, a PP cotton filter element, an activated carbon filter element or a composite filter element formed by compounding a plurality of the filter elements. The second filter element 300 may be a membrane filter element. Membrane cartridges include, but are not limited to, ultrafiltration membrane cartridges, reverse osmosis membrane cartridges, and the like. In other embodiments, the first filter element 200 can also be a membrane filter element, the second filter element can be a post-filter element, or any other suitable combination.
The first filter housing 220 and the second filter housing 320 may be removably coupled to each other by any suitable means, such as a threaded connection, a connector connection, and the like. When the first filter housing 220 and the second filter housing 320 are connected, the first filter cartridge 200 and the second filter cartridge 300 are in water path communication with each other inside the composite filter cartridge assembly 100 to form the integrated composite filter cartridge assembly 100. In this way, water may be filtered through multiple stages of the first filter housing 220 and the second filter housing 320 for use by a user.
The composite filter cartridge assembly 100 may have a water inlet and a water outlet. Water can enter the composite filter element assembly 100 through the water inlet of the composite filter element assembly 100, and after being filtered through the composite filter element assembly 100, the water flows out of the composite filter element assembly 100 through the water outlet so as to be used by a user. In the embodiment shown in fig. 4, the arrows schematically illustrate the direction of water flow within the composite cartridge assembly 100. The water inlet of the composite cartridge assembly 100 may be connected to the water inlet 201 of the first cartridge. Illustratively, the water inlet of composite cartridge assembly 100 may be communicated to the water inlet 201 of the first cartridge through an internal water path of composite cartridge assembly 100; or the water inlet 201 of the first filter element can be directly used as the water inlet of the composite filter element assembly 100. The water outlet 202 of the first filter element may be connected to the water inlet 301 of the second filter element. The water outlet of the second filter element 300 can be communicated to the water outlet of the composite filter element assembly 100. Illustratively, the water outlet of the second filter element 300 can be communicated to the water outlet of the composite filter element assembly 100 through an internal water channel of the composite filter element assembly 100; or the water outlet of the second filter element 300 can be directly used as the water outlet of the composite filter element assembly 100. Thus, after the primary filtration of the water through the first filter element 200, the secondary filtration can be performed again through the second filter element 300. Thus, by this arrangement, multi-stage filtration can be formed.
In other embodiments not shown in the figures, the composite cartridge assembly 100 may have various waterways therein. For example, in the embodiment where the first filter element 200 is a composite filter element including a front filter element and a rear filter element, and the second filter element 300 is a membrane filter element, the water may be filtered through the front filter element of the first filter element 200, then enter the membrane filter element, and then enter the rear filter element of the first filter element 200 again after being filtered through the membrane filter element. Depending on the first filter element 200 and the second filter element 300, the composite filter element assembly 100 may have various water paths therein as long as multi-stage filtration can be achieved. In order to prevent the filter element with high precision from being blocked, the precision of the filter element can be preferably increased from low to high along the direction of the water channel.
Through the arrangement, the composite filter element assembly 100 does not need to be provided with an external pipeline on the basis of forming multi-stage filtration, so that the structure is more compact, the occupied space is greatly reduced, the requirement on installation occasions is lower, and the applicability is stronger. This further facilitates the miniaturization of the equipment (e.g., water purifier) to which the composite filter element assembly 100 is applied. Meanwhile, since the first filter cartridge 200 and the second filter cartridge 300 are detachable, the filter cartridge to be replaced can be separately replaced. Therefore, all filter elements can be fully used, waste is avoided, and the use cost of equipment (such as a water purifier) using the composite filter element assembly 100 is reduced.
It should be noted that the present invention is not limited to the above-described embodiments, and many variations and modifications can be made in accordance with the teaching of the present invention. Illustratively, the composite cartridge assembly 100 may further include a third filter element, and the second filter housing 320 and the third filter housing of the third filter element are detachably connected to communicate the second filter element 300 and the third filter element in an internal water path of the composite cartridge assembly 100. Of course, the composite cartridge assembly 100 may also include a fourth cartridge or more. Such variations and modifications are intended to fall within the scope of the utility model as claimed.
Preferably, as shown in fig. 1 and 4, the first and second filter housings 220 and 320 are removably connected to each other at axial ends along the axial direction of the composite filter cartridge assembly 100. Through this kind of setting, can make full use of compound filter element subassembly 100's axial direction's space to reduce compound filter element subassembly 100's radial dimension, make compound filter element subassembly 100's appearance more regular, area is less. And because the water inlet and the water outlet of current filter core all set up the axial tip at straining the shell usually, connect like this and strain the shell transformation less to current filter core to reduce the cost of design and production.
Alternatively, the first filter housing 220 and the second filter housing 320 may be connected to each other by any other suitable means. Illustratively, the first and second filter housings 220 and 320 may also be connected in a radial direction of the composite filter element assembly 100, vertically, etc., as long as multi-stage filtration can be formed. However, since these approaches may result in an irregular shape of the composite cartridge assembly 100 or a greater retrofit to existing filter cartridges, one skilled in the art can select the relative positions of the first and second filter cartridges 220, 320 as desired.
Further, as shown in fig. 1-3, the first filter housing 220 may be provided with a spin-on slot 400, and the second filter housing 320 may be provided with a spin-on projection 500. In other embodiments not shown in the figures, the first and second filter housings 220 and 320 may be provided with a bayonet coupling and a bayonet coupling protrusion. The card rotating slot 400 and the card rotating protrusion 500 can be connected by rotating card. With this arrangement, the first filter housing 220 and the second filter housing 320 can be detachably coupled. The number and shape of the rotation locking grooves 400 and the rotation locking protrusions 500 are not limited. Illustratively, the number of the rotation-locking grooves 400 and the rotation-locking protrusions 500 may be only one, so that the rotation-locking grooves and the rotation-locking protrusions can realize rotation-locking connection; one or both of the rotation locking groove 400 and the rotation locking protrusion 500 may be plural, and the structure of each rotation locking groove 400 or each rotation locking protrusion 500 may be the same or different. In any case, it is sufficient that the first filter housing 220 and the second filter housing 320 can be detachably coupled by rotatably coupling the first filter housing with the rotation coupling groove 400 and the rotation coupling protrusion 500. Through the arrangement of the rotary clamping groove 400 and the rotary clamping convex block 500, the first filter shell 220 and the second filter shell 320 can be quickly and simply connected and detached, so that a user can easily complete the operation and the use experience is good.
A preferred arrangement of the rotation-locking groove 400 and rotation-locking protrusion 500 is described below in conjunction with fig. 1-3.
The rotation slot 400 may be L-shaped. The spin slot 400 may include an axial slot segment 410 and a circumferential slot segment 420. The axial slot segments 410 may extend in the axial direction of the composite cartridge assembly 100. The circumferential bayonet section 420 may extend from the axial bayonet section 410 in the circumferential direction of the composite core assembly 100. Thus, the rotation locking groove 400 can be formed in an L-shape.
The rotation-locking protrusion 500 may have an L-shape. The spin chuck tab 500 may include an axial chuck segment 510 and a circumferential chuck segment 520. The axial block section 510 may extend in the axial direction of the composite cartridge assembly 100. The circumferential block section 520 may extend from the axial block section 510 in a circumferential direction of the composite core assembly 100. Thus, the rotation locking protrusion 500 can be formed in an L-shape. The circumferential width of the axial slot segment 410 is greater than or equal to the sum of the circumferential widths of the axial and circumferential block segments 510 and 520.
The circumferential block section 520 may snap into the circumferential slot section 420. When the first filter housing 220 and the second filter housing 320 need to be connected, the rotary clamping lug 500 is aligned with the axial clamping groove section 410 along the axial direction of the composite filter element assembly 100 and inserted to the bottom, and then the first filter housing 220 and/or the second filter housing 320 are rotated to clamp the circumferential clamping block section 520 into the circumferential clamping groove section 420, so that the connection of the first filter housing 220 and the second filter housing 320 can be completed. When the circumferential block section 520 and the circumferential slot section 420 are clamped in place, the circumferential block section 520 can abut against the edge of the circumferential slot section 420 to play a limiting role. When it is desired to disassemble the first and second filter housings 220, 320, the first and second filter housings 220, 320 can be separated by first rotating the first and/or second filter housings 220, 320 to disengage the circumferential block section 520 from the circumferential groove section 420, realigning the rotational tabs 500 with the axial groove section 410 in the axial direction of the composite cartridge assembly 100, and then pulling the first and second filter housings 220, 320 in the opposite axial direction of the composite cartridge assembly 100. Through the arrangement, the structure of the rotary clamping groove 400 and the rotary clamping convex block 500 is simple, the structure is stable after connection, water leakage in the use process is avoided, and in addition, the production and the manufacturing are convenient, so that the production and the manufacturing cost of the composite filter element assembly 100 are reduced.
Further, as shown in fig. 2-3, a latch 430 may be disposed in the rotation-latching groove 400. The number and shape of the latch 430 are not limited. The rotation-locking protrusion 500 may be provided with a locking groove 530. The number and shape of the card slots 530 are not limited. When the rotation-locking protrusion 500 and the rotation-locking groove 400 are locked in place, the locking block 430 can be locked into the locking groove 530. In the embodiment shown in the figures, the latch 430 is disposed within the circumferential latch segment 420 and the latch 530 is disposed within the circumferential latch segment 520. In other embodiments not shown, the latch 430 may be disposed at any other suitable location on the snap-on slot 400. The locking slot 530 may be disposed at any other suitable location on the rotation locking protrusion 500. By providing the latch 430 and the catching groove 530, the structural strength of the connection of the first filter housing 220 and the second filter housing 320 can be increased. And the fixture block 430 and the clamping groove 530 are arranged to play a positioning role, so that the first filter shell 220 and the second filter shell 320 can be positioned accurately, the water gaps of the first filter element 200 and the second filter element 300 are ensured to be aligned accurately, the water channel between the first filter element and the second filter element is ensured to be smooth, and water leakage is avoided.
Preferably, as shown in fig. 1-3, an axial end of the first filter housing 220 (e.g., the third axial end 630 in the figures) may have a protruding mounting head 210 and an axial end of the second filter housing 320 (e.g., the second axial end 620 in the figures) may have a recessed mounting seat 310. The mounting head 210 may be mounted into the mounting seat 310. A first cartridge inlet 201 and a first cartridge outlet 202 may be provided on the mounting head 210. The spin slot 400 may be provided on an outer sidewall of the mounting head 210. The water inlet 301 of the second cartridge may be disposed within the mounting seat 310. The rotation-locking protrusion 500 may be disposed on an inner sidewall of the mounting seat 310. The mounting head 210 and the mounting base 310 may serve as guides so that the first and second filter housings 220 and 320 can be easily aligned when being coupled, thereby facilitating coupling. When installed, the outlet 202 of the first cartridge may be docked with the inlet 301 of the second cartridge.
In the preferred embodiment where the first filter element 200 is a front filter element and the second filter element 300 is a membrane filter element, both the water inlet 101 and the water outlet 102 of the composite filter element assembly can be disposed on the membrane filter element. Since the membrane filter element generally has a longer service life than the preceding filter element, that is to say the membrane filter element is replaced less frequently. Compare in the water inlet 101 with compound filter element group spare and the delivery port 102 setting of compound filter element group spare on leading filter core, set up the frequency that can reduce the water inlet 101 of compound filter element group spare and the delivery port 102 of compound filter element group spare and other parts be connected and dismantle on the membrane type filter core to reduce work load, improve and use experience.
Further, the membrane filter element may have oppositely disposed first and second axial ends 610, 620. The front cartridge can have oppositely disposed third and fourth axial ends 630, 640. The composite cartridge assembly water inlet 101 and composite cartridge water outlet 102 may both be disposed on the first axial end 610. The third axial end 630 and the second axial end 620 are removably connected. Through this kind of setting, can make full use of compound filter element subassembly 100's axial direction's space to reduce compound filter element subassembly 100's radial dimension, make compound filter element subassembly 100's appearance more regular, area is less. Because the water inlet and the delivery port of current filter core all set up the axial tip at straining the shell usually, above-mentioned structure is less to straining the seat transformation of current purifier to reduce the cost of design and production.
Preferably, as shown in fig. 4, a water passage 340 may be formed between the second filter housing 320 and the second filter 330. Referring collectively to fig. 1-4, the water inlet 101 of the composite cartridge assembly may be communicated to the water inlet 201 of the first cartridge via a water passage 340. The water inlet of the water channel 340 is communicated to the water inlet 101 of the composite filter element assembly, and the water outlet 341 (see fig. 3) of the water channel is communicated to the water inlet 201 of the first filter element. For example, in order to prevent water in the water passage 340 from directly passing through the second filter 330, a water barrier layer may be provided on the outside of the second filter 330. The water outlet 202 of the first filter element may be connected to the water inlet 301 of the second filter element. The outlet (not shown) of the second cartridge 300 may be connected to the outlet 102 of the composite cartridge assembly. As shown, water can enter the composite filter element assembly 100 through the water inlet 101 of the composite filter element assembly and then enter the first filter element 200 through the water passage 340 and the water inlet 201 of the first filter element in sequence for primary filtration. The water primarily filtered by the first filter element 200 can sequentially pass through the water outlet 202 of the first filter element and the water inlet 301 of the second filter element to enter the second filter element 300 for secondary filtration. The water after the secondary filtration by the second filter element 300 can flow out through the water outlet 102 of the composite filter element assembly for the user to use. With this arrangement, the modification of the internal structure of the second filter element 300 (i.e., the membrane filter element) is small, and the modification of the internal structure of the first filter element 200 (i.e., the pre-filter element) is not required, so that the composite filter element assembly 100 has low design and production costs.
