Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0037] Reference Figure 1 and Figure 2 A composite water purification filter element includes a filter element body 1, a positioning roller 101 is detachably inserted inside the filter element body 1, and a filter cotton layer 102 and an ultrafiltration membrane layer 103 are sequentially sleeved on the outer side of the positioning roller 101. The filter cotton layer 102 is specifically a coarse filter cotton, and the ultrafiltration membrane layer 103 is specifically an ultrafiltration membrane. It should be noted that

[0038] The coarse filter cotton of the filter cotton layer 102 is used to filter large particles of impurities in the water, such as sand, rust, etc., to protect the subsequent filter material;

[0039] The ultrafiltration membrane of the ultrafiltration membrane layer 103 is a precision filtration membrane that can effectively remove impurities such as bacteria, viruses and microorganisms in water while retaining minerals and trace elements that are beneficial to the human body;

[0040] In addition, an activated carbon layer is provided between the filter cotton layer 102 and the ultrafiltration membrane layer 103. The activated carbon layer uses natural minerals with adsorption effects, specifically activated carbon and coconut shell activated carbon, which can effectively remove impurities such as discoloration, odor and residual chlorine in the water. Coconut shell activated carbon has a high adsorption capacity and good filtering effect, and can effectively remove organic matter, heavy metals and other harmful substances in the water;

[0041] Secondly, a mineralization layer is arranged between the ultrafiltration membrane layer 103 and the positioning roller 101. By adding specific mineral materials into the filter element, the filtered water can be mineralized to make the water quality closer to the natural state, which is beneficial to human health. It needs to be expanded that the mineral materials can be: medical stone, weak base balls, etc. Medical stone is a natural silicate mineral with porosity and a large specific surface area. It can absorb harmful substances in the water and release minerals that are beneficial to the human body, such as calcium, magnesium, potassium, etc. Weak base balls are usually made of a variety of natural minerals and special materials. They can slowly release weak alkaline substances in the water, which helps to adjust the pH value of the water and make it closer to the weak alkaline environment required by the human body.

[0042] A second threaded tube 3 is provided on one side of the filter element body 1, and the water outlet end of the second threaded tube 3 is connected to a plurality of manifolds 4, which are distributed in a circular array on the outside of the filter element body 1, and each end of the plurality of manifolds 4 that is not connected to the second threaded tube 3 is connected to the interior of the filter element body 1. Water in the water pipe enters the plurality of manifolds 4 through the second threaded tube 3, and is discharged into the filter element body 1 from the water outlet ends of the plurality of manifolds 4, so that water enters the filter element body 1 more evenly and contacts the filter material, thereby avoiding uneven filtration of water by the filter material as much as possible, which helps to improve the filtration efficiency.

[0043] A plurality of water openings 1011 are formed through the positioning roller 101, and water in the filter element body 1 passes through the multi-layer filter material and is discharged through the water openings 1011. A plug 104 is detachably inserted inside the positioning roller 101, and a plurality of water inlet holes 105 are formed through the plug 104. Water passing through the water openings 1011 enters the plug 104 through the water inlet holes 105 and is discharged through one end of the plug 104. One end of the plug 104 is connected to a first threaded tube 109, and the water in the plug 104 is discharged through the first threaded tube 109, thereby completing the water filtering operation.

[0044] Specifically, according to the above technical solution, the second threaded tube 3 transports water to multiple manifolds 4, and the water is discharged into the filter element body 1 from the water outlet ends of the multiple manifolds 4, so that the water enters the filter element body 1 more evenly and contacts the filter material. The water passes through the filter cotton layer 102, the activated carbon layer, the ultrafiltration membrane layer 103 and the mineralized layer in turn. After multiple filtrations, the water passes through the water port 1011 and then enters the insert pipe 104 through the water inlet hole 105. The water in the insert pipe 104 is then discharged through the first threaded tube 109, completing the water filtering operation. The problem that the water enters the filter element body 1 and continuously impacts the same place of the filter material, causing the filter material to be gradually blocked by impurities, thereby causing the filtration efficiency of the filter material to decrease, is solved, and the purpose of uniform contact between water and the filter material is achieved.

[0045] Reference Figure 2A fixing ring 2 is detachably mounted on one end of the filter element body 1, and an annular threaded cover 106 is mounted on one end of the insert 104. The annular threaded cover 106 is threadedly connected to the fixing ring 2. The annular threaded cover 106 is unscrewed from the fixing ring 2 to facilitate the insert 104 to be taken out from the filter element body 1;

[0046] A screw 201 is installed on the fixing ring 2, and the fixing ring 2 is connected to the filter element body 1 through the screw 201. The screw 201 facilitates the disassembly and assembly of the fixing ring 2, and facilitates the removal of the fixing ring 2 from one end of the filter element body 1, thereby facilitating the removal of the positioning roller 101 and various filter materials, such as coarse filter cotton, ultrafiltration membrane, from the filter element body 1, thereby achieving the effect of facilitating the removal and replacement of the filter material inside the filter element body 1, which helps to reduce the use cost of the water purifier.

[0047] The side of the annular threaded cover 106 away from the insertion tube 104 is connected to a rotating tube 107 , and an anti-slip sleeve 108 is provided on the outer fixed sleeve of the rotating tube 107 . By holding the anti-slip sleeve 108 and rotating the rotating tube 107 , the annular threaded cover 106 can be easily disassembled and assembled.

[0048] Reference Figure 2 The outer side of the first threaded tube 109 is threadedly connected with a first threaded ring 110, which is used to connect to the drain end of the water purifier. The water entering the first threaded tube 109 is finally discharged from the water purifier through the drain end of the water purifier; the outer side of the second threaded tube 3 is threadedly connected with a second threaded ring 301, which is used to connect to the water inlet end of the water purifier. The second threaded ring 301 is used to connect the second threaded tube 3 to the water inlet end of the water purifier, so that the water entering the water purifier can enter the second threaded tube 3, ensuring that the water enters the filter element body 1.

[0049] Reference Figure 1 , Figure 3 as well as Figure 4 , a humidity reduction structure 5 is provided on the filter element body 1, and the humidity reduction structure 5 includes an air pump 501, an air inlet pipe 502 is installed at the output end of the air pump 501, and the end of the air inlet pipe 502 away from the air pump 501 is connected to the interior of the filter element body 1, and an air outlet pipe 504 is connected to the filter element body 1, and a first solenoid valve 503 is installed on the air inlet pipe 502, and a second solenoid valve 505 is installed on the air outlet pipe 504. When the water purifier is not used for a long time, the water in the water purifier is drained, so that the water in the filter element body 1 is also drained. At this time, the air pump 501 is started, so that the wind is blown into the filter element body 1 through the air inlet pipe 502, and then discharged from the air outlet pipe 504. In this process, the moisture in the filter element body 1 is continuously taken out, thereby achieving the effect of reducing the moisture inside the filter element body 1 through rapid air flow, which helps to prevent the filter material from being soaked in water when not in use, resulting in aging, bacteria breeding in the filter element body 1, and increased nitrite content.

[0050] A dustproof shell 506 is provided on the outside of the air pump 501, and a dustproof net 507 is installed on the dustproof shell 506. The wind entering the air inlet pipe 502 is first filtered by the dustproof net 507 to avoid external dust from entering the filter element body 1 and increasing the filtering burden of the filter material in the filter element body 1.

[0051] Working principle:

[0052] In the composite water purification filter element, water is transported to multiple manifolds 4 by the second threaded tube 3, and the water is discharged into the filter element body 1 from the water outlet ends of the multiple manifolds 4, so that the water enters the filter element body 1 more evenly and contacts the filter material. The water passes through the filter cotton layer 102, the activated carbon layer, the ultrafiltration membrane layer 103 and the mineralized layer in sequence. After multiple filtrations, the water passes through the water port 1011 and then enters the insert pipe 104 through the water inlet hole 105. The water in the insert pipe 104 is then discharged through the first threaded tube 109, completing the water filtering operation. The problem that water enters the filter element body 1 and continuously impacts the same place of the filter material, causing the filter material to be gradually blocked by impurities at that place, thereby causing the filtration efficiency of the filter material to decrease, is solved, and the purpose of uniform contact between water and the filter material is achieved.

[0053] When the composite water purification filter is not used for a long time, the water in the water purifier is drained, so that the water in the filter body 1 is also drained. At this time, the air pump 501 is started to blow air into the filter body 1 through the air inlet pipe 502 and then discharged from the air outlet pipe 504. In this process, the moisture in the filter body 1 is continuously brought out, thereby achieving the effect of reducing the moisture inside the filter body 1 through rapid air flow, which helps to prevent the filter material from being soaked in water when not in use, causing aging, bacteria growth in the filter body 1, and increased nitrite content.

[0054] The composite water purification filter element utilizes screws 201 to facilitate the removal of the fixing ring 2 from one end of the filter element body 1, thereby facilitating the removal of the positioning roller 101 and a variety of filter materials from the filter element body 1, thereby achieving the effect of facilitating the removal and replacement of the filter materials inside the filter element body 1, and helping to reduce the use cost of the water purifier.
