[0009] In order to explain in more detail the technical means and effects for achieving the object of the invention contemplated by the present invention, with reference to the drawings and preferred embodiments, the specific implementation manners, structures, features and their working effects of the present invention will be described in detail below.
[0010] As shown in FIGS. 1 to 3, the faucet filter cartridge of the present invention includes an outer cylinder 1, an inner cylinder 2, medical stone 3, an activated carbon filter 4 and an ultrafiltration membrane 5.
[0011] The top of the outer cylinder 1 has a water supply joint 11, and in order to facilitate the faucet connection, a fitting groove 12 is formed on the outer peripheral side of the receiving port.
[0012] The inner cylinder 2 is installed inside the outer cylinder 1 and is composed of a base 22, a partition frame 25, an upper cover 27, and a top cap 28 from bottom to top. A sealing ring is arranged between the upper cover 27 and the top cap 28. An outlet joint 21 is installed at the top of the inner cylinder 2 (the outlet joint 21 is installed on the top cap 28), and a water passing hole 23 is formed at the bottom (the water passing hole is installed on the base 22). The support frame 24 divides the inside of the inner cylinder 2 into two chambers up and down.
[0013] A water passing gap 15 is formed between the outer cylinder 1 and the inner cylinder 2. The water passing gap 15 communicates the water supply joint 11 and the water passing hole 23. In order to ensure the maintenance of the water passing gap 15, the smoothness of the water flow, and the position stability of the inner cylinder 2, the following structure is adopted: An upper support protrusion 13 that presses against the outer top of the inner cylinder 2 is installed at the inner top of the outer cylinder 1. A flange 29 that contacts the inner peripheral side wall of the outer cylinder 1 is formed on the outer peripheral side of the top cap 28 (a water passing hole is installed in the flange 29). A lower support protrusion 14 that supports the bottom of the inner cylinder 2 is installed at the inner bottom of the outer cylinder 1.
[0014] Fill the water passing gap 15 with the medical stone 3. Place the ultrafiltration membrane 5 in the upper chamber and accommodate the activated carbon filter 4 in the lower chamber. The raw water from the faucet is filtered into purified water through the sequence of the water supply joint 11 → the medical stone 3 → the water passing hole 23 → the activated carbon filter 4 → the ultrafiltration membrane 5, and flows out from the water outlet joint 21.
[0015] In this embodiment, the ultrafiltration membrane 5 is a hollow fiber membrane with a pore size of 0.01 μm.
[0016] In this embodiment, a support frame 24 is installed at the position of the water passing hole 23, and through holes 26 for communicating the upper and lower two upper chambers and the lower chamber are formed in the partition frame 25.
[0017] In this embodiment, the activated carbon filter 4 is a structure formed by mixing and molding activated carbon particles and activated carbon fibers, and is provided with a hydrophilic non-woven fabric 41 to prevent the outflow of the activated carbon particles. The hydrophilic non-woven fabric 41 is formed in a cylindrical shape in a state of covering the entire activated carbon filter 4, and its lower end surface completely covers the water passing hole 23 of the base 22, and its upper end surface is arranged to cover all the through holes 26 of the partition frame 25.
[0018] In this embodiment, in order to fix the position of the cylindrical activated carbon filter 4, a lower positioning lip 22a surrounding the water passing hole 23 is provided on the upper surface of the base 22, and an upper positioning lip 25a surrounding all the through holes 26 is provided on the lower surface of the partition frame 25, and the activated carbon filter 4 is fixed and arranged between the upper and lower lower positioning lips 22a and upper positioning lips 25a.
[0019] In this device, the connection is completed by rotating the water supply joint 11 by a predetermined angle in a state where it is aligned with the fitting position of the dedicated faucet adapter, and it can immediately shift to the operating state.
[0020] The embodiments disclosed in this specification are merely exemplary embodiments for facilitating the understanding of this utility model, and do not limit the scope of the claims of this utility model registration.
