Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring now to fig. 1-4, a water purification cartridge 100 according to an embodiment of the present invention is described, wherein the water purification cartridge 100 may be a PP cotton cartridge, a carbon rod cartridge, or an RO cartridge.

The water purification cartridge 100 includes: a filter flask 10, a water separation sleeve 20 and a filter material 50.

Specifically, the filter flask 10 defines a filter chamber 11 having an inlet 111 and an outlet 112, a water distribution sleeve 20 is disposed within the filter chamber 11, the water distribution sleeve 20 having first and second ends in communication with each other and a water passage hole 21 extending through the wall thickness of the water distribution sleeve 20. In other words, the water diversion cover 20 is a cylindrical structure with two open ends. Wherein, the filter material 50 is placed in the water dividing sleeve 20.

In which water flows through the filter material 50 from the outside to the inside. Thus, a water flow channel is formed between the inner wall of the filter bottle 10 and the outer wall of the water diversion sleeve 20, and water flow enters the filter material 50 under the action of water pressure for filtration. After water flow enters from the inlet 111 of the filter flask 10, the water diversion sleeve 20 guides the water flow into the water flow passage and disperses the water flow to different areas of the filter material 50 through the water through holes 21, so that the filter material 50 in different areas can obtain enough water, and the filter material 50 can be fully and effectively used.

Of course, the water flow may penetrate from the inside to the outside of the filter medium 50. In this case, the water distribution sleeve 20 indirectly regulates the amount of the filtered water flowing out of the filter medium 50 by regulating the flow resistance of the filtered water, thereby indirectly regulating the amount of the filtered water flowing into different regions of the filter medium 50.

The shape of the water passage hole 21 may be one or more of a circle, an oval, a square, a diamond, and a polygon.

From this, according to the utility model discloses water purification filter core 100 is through setting up the cover 20 that divides that is used for dispersion rivers in filter flask 10 to make rivers get into the different regions of filter media 50 more evenly, improve the whole rate of utilization of filter media 50, and then improve water purification filter core 100's life.

In some embodiments of the present disclosure, the flow aperture 21 is smaller per unit of flow adjacent the inlet 111 of the filter flask 10 than the flow aperture 21 remote from the inlet 111 of the filter flask 10. It is understood that the water pressure is large near the inlet 111 of the filter flask 10, and therefore, the unit flow rate of the water passage hole 21 near the inlet 111 is set small; since the water pressure at the inlet 111 far from the filter flask 10 is small, the unit flow rate of the water passage hole 21 far from the inlet 111 is set to be large. Therefore, water flow can enter different areas of the filter material 50 under different water pressures and different unit throughputs, so that the water flow of the different areas of the filter material 50 is approximately the same, and the service life of the filter material 50 is integrally prolonged. Here, the "unit flow rate" refers to the amount of water flowing through the water passage hole 21 per unit time, and the form of the water passage hole 21 is not limited.

In an alternative embodiment, as shown in fig. 1 and 2, the water passage holes 21 include a plurality of layers distributed along the circumferential direction, the water passage holes 21 in the same layer have the same size, and the adjacent water passage holes 21 in the same layer have the same pitch. Since the water distribution jacket 20 is wound around the outer periphery of the filter medium 50, the size of the water passage holes 21 in the same layer and the pitch between adjacent water passage holes 21 are set to be the same, and the same amount of water can be absorbed by the filter medium 50 in the same circumferential direction.

The size and the distance between adjacent layers of the water through holes 21 can be set according to the positions of the inlet 111 and the outlet 112 of the filter flask 10.

For example, in some alternative examples, as shown in fig. 3 and 4, the inlet 111 and the outlet 112 are respectively located at the upper end and the lower end of the filter flask 10, and the axial distance between adjacent layers gradually decreases from the end adjacent to the inlet 111 of the filter flask 10 to the end away from the inlet 111 of the filter flask 10. That is, in the case where the inlet 111 is located at the upper end of the filter flask 10 and the outlet 112 is located at the lower end of the filter flask 10, the axial intervals of the water passage holes 21 in adjacent layers are gradually decreased from top to bottom. In other words, the density of the water passage holes 21 on the lower side of the jacket 20 is greater than the density of the water passage holes 21 on the upper side. Wherein the arrows in fig. 3 and 4 are the flow direction of the water flow.

In other embodiments of the present invention, as shown in fig. 1 and 2, the water passage holes 21 include a plurality of layers distributed along the circumferential direction, and the water passage holes 21 are distributed at equal intervals in the circumferential direction and the axial direction. That is, the water passing holes 21 are uniformly distributed on the water distribution sleeve 20, and in this case, the unit flow areas of the water passing holes 21 may be the same, so that the water distribution sleeve 20 is simple to manufacture and mold and has a poor water distribution effect. Therefore, in order to achieve a preferable water separation effect, the unit flow area of the water passage holes 21 may be selected to be different, for example, the unit flow area of the water passage holes 21 close to the inlet 111 is set to be small, and the unit flow area of the water passage holes 21 far from the inlet 111 is set to be large, so that the amount of water passing through different regions of the filter medium 50 is more preferably adjusted.

In an optional embodiment, the water through holes 21 are square, the length l of each water through hole ranges from 8 mm to 11 mm, the width w of each water through hole ranges from 3 mm to 5 mm, and the axial distance h between the water through holes 21 of adjacent layers ranges from 2 mm to 5 mm. The inventors have found that the size of the water passage holes 21 and the axial distance between adjacent water passage holes 21 can reduce the difference in the water passing amount of the filter medium 50 in different regions, thereby extending the service life of the filter medium 50.

In other embodiments of the present invention, the first end cap 30 and the second end cap 40 are respectively disposed at two ends of the filter material 50, and two ends of the water diversion cover 20 are respectively connected to the first end cap 30 and the second end cap 40. In this way, the displacement of the filter material 50 in the axial direction can be limited by the first end cap 30 and the second end cap 40, and the filter material 50 is wrapped in the water diversion sleeve 20, so that the filter material 50 is effectively isolated from the outside, and the filter material 50 is prevented from being polluted by the outside.

Optionally, the first end cap 30 and the water diversion cover 20 and the second end cap 40 and the water diversion cover 20 are connected by a snap-fit manner. Therefore, the first end cover 30 and the second end cover 40 can be conveniently assembled and separated from the water distribution sleeve 20, and the assembling and disassembling efficiency of the water purification filter element 100 is improved.
