Description

Technical Field

[0001] This utility model relates to the field of filter elements, and more particularly to a filter element with an internal and external combination. Background Technology

[0002] Existing filter cartridges use origami for filtration. Although origami has a high filtration area, when water flows evenly into various areas of the origami, it will increase the flow rate to a certain extent. However, this even water flow distribution will cause impurities to accumulate rapidly on the surface of the origami, which will aggravate the clogging of the origami and ultimately reduce its service life. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an internal and external combined filter element and a water dispenser incorporating it.

[0004] The filter element of the first aspect of this utility model includes a paper fold and an activated carbon filter material. The paper fold has a water outlet cavity inside and the outer side of the paper fold is a first water inlet surface. The activated carbon filter material is annular and is sleeved on the outside of the paper fold. The outer side of the activated carbon filter material is a second water inlet surface and the inner side of the activated carbon filter material is a water outlet surface. The water outlet surface is connected to the first water inlet surface.

[0005] Furthermore, an electrostatic filter membrane is fitted onto the outer side of the activated carbon filter material.

[0006] Furthermore, the upper end of the activated carbon filter material is higher than the upper end of the electrostatic filter membrane, and the lower end of the activated carbon filter material is lower than the lower end of the electrostatic filter membrane.

[0007] Furthermore, the distance between the upper end of the activated carbon filter material and the upper end of the electrostatic filter membrane is 15mm-30mm, and the distance between the lower end of the activated carbon filter material and the lower end of the electrostatic filter membrane is 15mm-30mm.

[0008] Furthermore, the origami is ring-shaped, and grids are provided on both the inner and outer sides of the origami.

[0009] Furthermore, an inner frame is provided inside the water outlet cavity, and the interior of the inner frame has a water outlet channel, which communicates with the water outlet cavity outside the inner frame.

[0010] Furthermore, the origami is detachably installed between the inner frame and the activated carbon filter material.

[0011] Furthermore, the origami includes a plurality of n-shaped bends and a plurality of connecting portions. The plurality of bends are spaced apart along the circumferential direction of the filter element. The openings of the bends face the center of the filter element. Each pair of adjacent bends are connected by a connecting portion.

[0012] The filter element with the inner and outer combination according to this utility model has at least the following technical effects:

[0013] 1. By placing the origami inside the activated carbon filter media, the raw water passes through the activated carbon filter media and the origami in sequence for filtration. Since the activated carbon filter media can intercept large particles in the tap water, it prevents these large particles from accumulating quickly on the origami, reducing the degree of clogging and thus extending the service life of the origami.

[0014] 2. By installing an electrostatic filtration membrane on the outer layer of the activated carbon filter material, the electrostatic filtration membrane can capture particulate matter or charged substances in the raw water, thereby increasing the filtration area.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figure 1 As shown, the filter element of the first embodiment of this utility model includes a paper fold 100 and an activated carbon filter material 200. The paper fold 100 has a water outlet cavity 110 inside, and the outer side of the paper fold 100 is a first water inlet surface 120. The activated carbon filter material 200 is annular and is sleeved on the outside of the paper fold 100. The outer side of the activated carbon filter material 200 is a second water inlet surface 210, and the inner side of the activated carbon filter material 200 is a water outlet surface 220. The water outlet surface 220 is connected to the first water inlet surface 120.

[0029] By placing the origami 100 inside the activated carbon filter material 200, the raw water passes through the activated carbon filter material 200 and the origami 100 in sequence for filtration. Since the activated carbon filter material 200 can intercept large particles in the tap water, it prevents these large particles from accumulating rapidly on the origami 100, reduces the degree of clogging of the origami 100, and thus extends the service life of the origami 100.

[0030] During operation, raw water enters the activated carbon filter material 200 from the outside through the second inlet surface 210. The activated carbon filter material 200 filters out large particles in the raw water. After preliminary filtration and purification, the raw water is discharged from the outlet surface 220. The discharged raw water then enters the folding paper 100 from the first inlet surface 120. The high-precision folding paper 100 further purifies the raw water, filtering out even finer particles. After filtration by the folding paper 100, the raw water is discharged from the outlet chamber 110.

[0031] Specifically, the activated carbon filter material 200 is made of activated carbon and carbon fiber composite molding.

[0032] Furthermore, such as Figure 1 As shown, an electrostatic filter membrane 230 is fitted on the outer side of the activated carbon filter material 200.

[0033] By providing an electrostatic filter membrane 230 on the outer layer of the activated carbon filter material 200, the electrostatic filter membrane 230 can capture particulate matter or charged substances in the raw water, thereby increasing the filtration area.

[0034] Furthermore, such as Figure 2 As shown, the upper end of the activated carbon filter material 200 is higher than the upper end of the electrostatic filter membrane 230, and the lower end of the activated carbon filter material 200 is lower than the lower end of the electrostatic filter membrane 230.

[0035] With the above configuration, the upper end of the activated carbon filter media 200 is offset from the upper end of the electrostatic filter membrane 230, and the lower end of the activated carbon filter media 200 is offset from the lower end of the electrostatic filter membrane 230. Thus, when the electrostatic filter membrane 230 becomes clogged, raw water can enter the activated carbon filter media 200 through the offset ends. This not only effectively purifies the raw water but also increases the filtration area, protects the activated carbon filter media 200, and gives it a longer lifespan.

[0036] Furthermore, the distance between the upper end of the activated carbon filter material 200 and the upper end of the electrostatic filter membrane 230 is 15mm-30mm, and the distance between the lower end of the activated carbon filter material 200 and the lower end of the electrostatic filter membrane 230 is 15mm-30mm.

[0037] By using the above numerical range, the activated carbon filter material 200 can have a longer lifespan.

[0038] Specifically, the distance between the upper end of the activated carbon filter material 200 and the upper end of the electrostatic filter membrane 230 is 20mm, and the distance between the lower end of the activated carbon filter material 200 and the lower end of the electrostatic filter membrane 230 is 20mm.

[0039] Furthermore, such as Figure 1 , 3 As shown, the origami 100 is ring-shaped, and grids 130 are provided on both the inner and outer sides of the origami 100.

[0040] The inner and outer layers of the origami 100 are equipped with grids 130, which effectively prevents the origami 100 from sticking together after prolonged water exposure, thus avoiding affecting the water inlet and outlet channels (for example, preventing the origami 100 at point A and the origami 100 at point B from sticking together), thereby ensuring sufficient water-passing area.

[0041] Specifically, grid 130 is a soft grid.

[0042] Specifically, such as Figure 1 As shown, the origami 100 includes a plurality of n-shaped bends 130 and a plurality of connecting portions 140. The plurality of bends 130 are spaced apart along the circumferential direction of the filter element. The openings of the bends 130 face the center of the filter element. Each pair of adjacent bends 130 are connected by a connecting portion 140.

[0043] Furthermore, such as Figure 1 As shown, an inner frame 300 is provided inside the water outlet cavity 110, and the interior of the inner frame 300 has a water outlet channel 310, which is connected to the water outlet cavity 110 outside the inner frame 300.

[0044] The inner frame 300 is located inside the water outlet cavity 110, and the inner frame 300 has a water outlet channel 310. Thus, the inner frame 300 can both support the origami 100 and serve as a component for discharging pure water.

[0045] During operation, the water filtered by the origami 100 enters the inner frame 300 and is discharged from the filter element through the water outlet channel 310 of the inner frame 300.

[0046] Specifically, the sidewall of the inner frame 300 has a connecting hole (not shown in the figure), and the water outlet channel 310 is connected to the water outlet cavity 110 outside the inner frame 300 through the connecting hole.

[0047] Furthermore, such as Figure 1 As shown, the origami 100 is detachably installed between the inner frame 300 and the activated carbon filter media 200, thus making the origami 100 detachable for easy replacement. It also allows other functional filter media (such as lead removal, sterilization, scale inhibition, etc.) to be installed between the inner frame 300 and the activated carbon filter media 200, thereby extending the lifespan of the filter media.

[0048] The water dispenser of the second embodiment of this utility model includes the filter element of the first embodiment. By providing the filter element of the first embodiment, the service life of the filter element is improved.

[0049] Although the technical solutions of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these technical solutions without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents.
