As shown in fig. 2, the filter cartridge assembly 201 includes a filter bottle 1 and a filter cartridge 2. The filter flask 1 is provided with a water inlet 114 and a water outlet 115. The filter element 2 is arranged in the filter flask 1 and forms a filtering flow channel together with the filter flask 1, and the filtering flow channel is respectively communicated with the water inlet 114 and the water outlet 115. The filtering flow passage comprises a water inlet flow passage, a water outlet flow passage and a plurality of filtering pores arranged on the circumferential side wall of the filter element 2, and the filtering pores are communicated with the water inlet flow passage and the water outlet flow passage. Raw water enters the water inlet flow channel from the water inlet 114, enters the water outlet flow channel through the filtering pores on the surface of the filter element 2, and is filtered, so that the water in the water outlet flow channel carries strontium element and is discharged from the water outlet 115.

Specifically, to achieve the release of the strontium element, the filter element 2 includes a columnar mineralized filter element main body 21, and the mineralized filter element main body 21 can release the strontium element into water. An outlet flow channel is formed in the mineralization filter element main body 21, one end of the outlet flow channel is communicated with the water outlet 115, and the other end is closed. In the embodiment, the mineralized filter element main body 21 is adopted to release the strontium element into water so as to meet the requirement of human body on the intake of the strontium element. In addition, the mineralization filter element body 21 can change water into weakly alkaline water, for example, change the pH of the water to 7.5-8.0.

In order to increase the contact area between the main body 21 of the mineralization filter element and water, the main body 21 of the mineralization filter element is made of granular filter materials so as to form filter pores on the circumferential side wall of the main body 21 of the mineralization filter element, so that water can pass through the main body 21 of the mineralization filter element from the water inlet flow passage and enter the water outlet flow passage.

Maifanitum is a natural silicate mineral, and mainly contains inorganic aluminosilicate mineral which is nontoxic and harmless to living beings. The medical stone also contains alumina which is used as a neutral oxide, and reacts with alkali in an aqueous solution to reduce the pH value and reacts with acid to increase the pH value, so that the medical stone has the function of adjusting the pH value of water in two directions. Besides, the medical stone can release nearly twenty trace elements such as strontium, boron, zinc and the like, can improve water quality, and is beneficial to human health.

The zeolite has good removal effect on the amlodipine, the removal rate is more than 95%, the zeolite has strong pollutant interception capability, good removal capability on the turbidity of water, and the average removal rate on the turbidity is 65%. In addition, the zeolite is also beneficial to loosening and making the main body 21 of the mineralization filter element porous, increasing the adsorbability of the main body 21 of the mineralization filter element to macromolecular colloidal organic matters and improving the filtering performance of the main body 21 of the mineralization filter element.

In order to balance the performances of various granular filter materials in the mineralization filter element main body 21, the mass ratio of the activated carbon, the dolomite, the anorthite, the medical stone and the zeolite in the filter material is (100-: (6-8): (3-5): (1-2): (1-2), for example, it may specifically be 110: 6: 3: 2: 2.

The valve body 31 includes a core body 311 and a stopper portion 312 at an end of the core body 311. Core 311 slidably extends through inlet 114 and is spaced from the inner wall of inlet 114; the stopper 312 is located inside the filter flask 1. When the filter cartridge assembly 201 is assembled, the core 311 moves toward the interior of the bottle 11. The elastic member 32 is pressed, and the blocking portion 312 is separated from the inner wall of the filter flask 1 to conduct the water inlet 114, so that the raw water enters the filter flask 1 through the gap between the core body 311 and the water inlet 114. When the filter element assembly 201 is detached, the elastic element 32 is released, and the core body 311 is driven to move towards the outside of the bottle body 11, so that the core body 311 drives the blocking part 312 to abut against the inner wall of the filter bottle 1, and further the water inlet 114 is blocked.

In order to enable the blocking portion 312 to block the water inlet 114, the maximum outer diameter of the blocking portion 312 is larger than the diameter of the water inlet 114, and the projection of the blocking portion 312 along the vertical direction completely covers the water inlet 114, so as to ensure that the blocking portion 312 can completely block the water inlet 114.

In order to prevent the core 311 from being separated from the water inlet 114, a limiting portion 313 is further disposed at one end of the core 311, which is located outside the water inlet flow passage, and the maximum outer diameter of the limiting portion 313 is greater than the diameter of the water inlet 114, so that the limiting portion 313 can abut against the filter flask 1 to limit the core 311 to continue to move into the filter flask 1.

Further, the elastic member 32 may be a spring, which is beneficial for reducing the cost of the filter element assembly 201. The spring cover is established outside core 311 to for the deformation of spring provides the guide effect, avoid the spring crooked core 311 card pause. Specifically, one end of the spring abuts or is connected to the filter flask 1, and the other end of the spring abuts or is connected to the stopper portion 313.

To further enhance the sealing effect of the sealing portion 312 on the water inlet 114, the sealing portion 312 is made of an elastic material so that the sealing portion 312 can deform to further seal the water inlet 114 when contacting the inner wall of the filter flask 1.

To facilitate the assembly of the valve element 31 with the filter flask 1, the blocking portion 312 may have a conical structure. Correspondingly, the water inlet 114 is configured as a tapered hole, the aperture of the tapered hole is gradually reduced from the outside of the filter flask 1 to the inside of the filter flask 1, and the large-diameter end of the tapered hole is the outer end of the water inlet 114. When the valve core 31 and the filter flask 1 are assembled, the blocking part 312 is deformed to enter the filter flask 1 through the water inlet 114 by external force. The stopper 312 is deformed and restored after entering the filter flask 1 so that the stopper 312 can abut against the inner wall of the filter flask 1 to block the water inlet 114.

In addition, the water inlet 114 is configured as a tapered hole, which can increase the aperture of the outer end of the water inlet 114, and can increase the gap between the core 311 and the inner wall of the water inlet 114 on the basis that the diameter of the core 311 is not changed, so as to improve the inflow rate.

In this embodiment, at least two water inlets 114 are provided, one water outlet 115 is provided, and at least two water inlets 114 are disposed around the circumference of the water outlet 115, so as to uniformly introduce raw water into the annular water inlet flow channel. Specifically, the bottle 11 includes a bottom plate 111 and a body 112. The water inlet 114 and the water outlet 115 are both disposed on the bottom plate 111.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the utility model. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
