Referring to fig. 1-3, a first embodiment of the present invention provides a filter element 1 of a water purifier, which includes a P cotton filter element 11, a hollow ultrafiltration membrane bundle 12, and a hollow base 13 fixedly connected to two ends of the hollow ultrafiltration membrane bundle 12; the inner part of the P P cotton filter element 11 is hollow to form an accommodating cavity 111, the accommodating cavity 111 is matched with the hollow ultrafiltration membrane wire bundle 12, and at least part of the inner wall of the hollow base 13 is in interference fit with the outer wall of the P cotton filter element 11; when the P P cotton filter element 11 is embedded into the hollow base 13, the accommodating cavity 111 accommodates the hollow ultrafiltration membrane wire bundle 12, and the two end ports of the hollow ultrafiltration membrane wire bundle 12 are flush with one end of the hollow base 13, which is far away from the P cotton filter element 11.

As can be understood, the hollow ultrafiltration membrane wire bundle 12 includes a plurality of hollow ultrafiltration membrane wires, each hollow ultrafiltration membrane wire is hollow inside to form a flow channel 121, and liquid can permeate from the outer surface of the hollow ultrafiltration membrane wire, enter the flow channel 121, and flow out from the two end ports of the hollow ultrafiltration membrane wire to complete filtration.

Specifically, 12 both ends fixed connection's cavity base 13 are tied in a bundle to the cavity ultrafiltration membrane silk, and cavity ultrafiltration membrane silk both ends port and cavity base 13 keep away from the one end of the cotton filter core of P P11 when neat, and the both ends of many cavity ultrafiltration membrane silks are fixed connection cavity base 13 also, and many cavity ultrafiltration membrane silk both ends port also flushes with the one end that the cotton filter core of P11 was kept away from to cavity base 13.

Understandably, when the P cotton filter element 11 is embedded into the hollow base 13, the hollow ultrafiltration membrane wire bundle 12 is located in the containing cavity 111 of the P cotton filter element 11, so that when filtering, to-be-filtered water firstly permeates from the outer surface of the P cotton filter element 11 and enters the containing cavity 111 inside, so as to perform primary filtering, and effectively remove various particle impurities in the to-be-filtered water. The water to be filtered which enters the accommodating cavity 111 and is subjected to primary filtering can permeate from the outer surfaces of the hollow ultrafiltration membrane filaments in the hollow ultrafiltration membrane filament bundle 12, enter the circulation channel 121 of the hollow ultrafiltration membrane filaments and flow out from the two end ports of the hollow ultrafiltration membrane filaments fixed on the hollow base 13, so that secondary filtering is completed. That is, the water filtered by the hollow ultrafiltration membrane wire bundle 12 is filtered by the P P P cotton filter element 11, so that the problems of blockage and pollution of various particle impurities in the water to be filtered by the ultrafiltration membrane wire bundle are effectively prevented, and the service life of the hollow ultrafiltration membrane wire bundle 12 is prolonged. In addition, the water after twice filtration is cleaner.

It can be understood that the inner wall of the hollow base 13 is at least partially in interference fit with the outer wall of the P cotton filter element 11, so as to prevent the P cotton filter element 11 from moving, and to achieve the sealing effect there, so as to prevent the water to be filtered from entering there and affecting the filtering quality.

It is understood that the hollow base 13 and the cotton filter element 11 may be detachably connected. The P P cotton filter element 11 has low cost, and after the filter element 1 of the water purifier is used for filtering for a period of time, the P cotton filter element 11 can be replaced for secondary filtering, thereby reducing the cost.

Further, the water purifier filter element 1 also comprises a flexible binding net, the flexible binding net is sleeved with a hollow ultrafiltration membrane wire bundle 12, and one end of the flexible binding net is fixedly connected with a hollow base 13; when the P P cotton filter element 11 is embedded into the hollow base 13, the accommodating cavity 111 accommodates and is sleeved with the flexible binding net far away from the outer side surface of the hollow ultrafiltration membrane wire bundle 12; the P P cotton filter element 11, the flexible binding net and the hollow ultrafiltration membrane wire bundle 12 are sequentially attached from outside to inside.

It will be appreciated that the flexible restraining net is made of a flexible material. The size of the flexible binding net is matched with the size of the hollow ultrafiltration membrane wire bundle 12, so that when the hollow ultrafiltration membrane wire bundle 12 is sleeved with the flexible binding net, the hollow ultrafiltration membrane wire bundle 12 can be bound, the hollow ultrafiltration membrane wire bundle 12 with two fixed ends is prevented from being scattered, and the P cotton filter element 11 is favorably embedded into the hollow base 13. The size and the shape of the meshes of the flexible binding net are not limited, and the requirement that water to be filtered after being filtered by the P P cotton filter element 11 can permeate from the outer surface of the hollow ultrafiltration membrane wire bundle 12 is met.

It can be understood that the hollow base 13 can be injected with resin glue 14, so that the resin glue 14 wraps and adheres to the hollow ultrafiltration membrane wire bundle 12 and to the inner side wall of the hollow base 13, to complete the fixed connection between the two ends of the hollow ultrafiltration membrane wire bundle 12 and the hollow base 13, and the two end ports of the hollow ultrafiltration membrane wire bundle 12 are flush with the end of the resin glue 14 far from the P cotton filter element 11. That is, the resin adhesive 14 only wraps and adheres to the outer surfaces of the two ends of the hollow ultrafiltration membrane filaments in the hollow ultrafiltration membrane filament bundle 12 when wrapping and adhering the hollow ultrafiltration membrane filament bundle 12, and does not wrap and adhere the two ends of the hollow ultrafiltration membrane filaments, so that the water to be filtered, which permeates through the outer surfaces of the hollow ultrafiltration membrane filaments, can still flow out from the two ends.

It is understood that the positions of the ports at the two ends of the hollow ultrafiltration membrane filaments in the hollow ultrafiltration membrane filament bundle 12 are not limited, and may be set according to specific situations. Optionally, the arrangement can be performed according to a preset array, so that water filtered by the hollow ultrafiltration membrane filaments flows out more uniformly.

Understandably, the inner wall of the P cotton filter element 11 can be provided with a reinforcing trace 113, that is, the wall of the accommodating cavity 111 of the P cotton filter element 11 is provided with the reinforcing trace 113, the reinforcing trace 113 can be embedded into the hollow base 13 in the P cotton filter element 11, and when the accommodating cavity 111 accommodates the hollow ultrafiltration membrane wire bundle 12, the reinforcing trace 113 can abut against the hollow ultrafiltration membrane wire bundle 12, so that the hollow ultrafiltration membrane wire bundle 12 is more compact and stable.

It can be understood that when the hollow ultrafiltration membrane wire bundle 12 is sleeved with the flexible binding net, the reinforcing traces 113 abut against the flexible binding net and then abut against the hollow ultrafiltration membrane wire bundle 12.

Further, the cotton filter core 11 of P P includes that at least two-layer can tear the cotton P of drawing, and the inner wall diameter of cavity base 13 increases in proper order along the opposite direction of the cotton filter core 11's of P embedding direction.

It is understood that the cotton P filter element 11 may include at least two layers of tearable P cotton, and after using the water purifier filter element 1 for a period of time, a user may tear off the outermost layer of tearable P cotton to prevent the influence of the filtered particle impurities left on the surface of the outermost layer of tearable P cotton on the filtering, and in addition, the cost can be reduced. And the diameter of the inner wall of the hollow base 13 is sequentially increased along the opposite direction of the embedding direction of the cotton filter element of P P11, so that the diameter corresponding to the position where the cotton filter element of P11 is embedded into the hollow base 13 is larger than the diameter corresponding to the position where the cotton filter element of P11 is embedded into the hollow base 13 after a layer of the cotton filter element of P11 is torn off. After tearing off a layer of tearable cotton pp, the cotton pp filter element 11 can still be embedded into the hollow base 13, and the embedding is more stable.
