It should be understood that such data may be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0025] Referring to the accompanying drawings of the specification, an anti-soaking filter element includes a housing 10 for placing a filter material 100 inside. One end of the housing is provided with an opening 11, and a pressing plate 20 is arranged inside the other end of the housing. An elastic body 21 is arranged between the pressing plate and the other end of the housing. A filter material is placed between the pressing plate and the opening. In the present invention, the elastic body can be a spring, which mainly maintains the compactness of the filter material and ensures its stability when mixed with water. A first sealing ring 22 is arranged between the outer peripheral wall of the pressing plate and the inner peripheral wall of the housing, so as to prevent the filter material from running into the space between the pressing plate and the following end cap.

[0026] Further, the housing includes a cooperating cylinder 12 and an end cap 13. One end of the cylinder has an opening, and the opening is arranged at the other end of the cylinder. The end cap is located at the other end of the housing and is connected to one end of the cylinder. A first convex ring 14 is arranged on the end face of the end cap facing the pressing plate, and a second convex ring 23 is arranged on the end face of the pressing plate facing the end cap. An elastic body is arranged between the first convex ring and the second convex ring. As described above, the elastic body is a spring, so that both ends of the spring are respectively sleeved on the outer periphery of the first convex ring and the second convex ring.

[0027] Specifically: A rotatable handle 15 is provided on the other end face of the end cap, which facilitates the installation of the entire filter element in the later stage. After installation, the handle is rotated and folded to reduce the occupied space. An annular protrusion 16 is provided on one end face of the end cap and is located outside the first convex ring. The inner circumference of the annular protrusion is fitted and connected to the outer circumference of one end of the cylinder body. During use, after the cylinder body and the cover body are fitted, glue is used for sealing. Of course, a threaded connection method can also be used to connect the end cap and the cylinder body. At the same time, a clamping block 71 can be provided on the outer circumference of the cylinder body, and a clamping interface 72 matching the clamping block is provided on the annular protrusion.

[0028] In an embodiment of the present invention, a connecting ring 30 is provided inside the housing at the opening. A connecting plate 31 is provided in the middle of the connecting ring. A water passing hole 32 is provided on the connecting plate. A second sealing ring 33 is provided between the outer peripheral wall of the connecting ring and the inner peripheral wall of the housing. The connecting ring is located between the filter material and the opening. A filter screen 40 located between the filter material and the connecting plate is provided inside the connecting ring. In one embodiment, the filter screen is a high-density filter screen, and a mixing area 50 is formed between the connecting plate and the opening. The aperture of the opening is 0.3 - 0.7 mm. Preferably, the aperture of the opening can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm.

[0029] More specifically: The housing further includes a connector 18, which is connected to one end of the cylinder body. The connector is provided with a water inlet channel 181 and a water outlet channel 182 that are fitted and connected to the opening. In the present invention, water enters from the water inlet channel, a part of it flows into the opening, then mixes with the filter material and then flows out of the opening and mixes with another part and then flows out from the water outlet channel.

[0030] In a preferred embodiment of the present invention, a soft rubber plug 60 that can be installed in the water inlet channel is further included. The soft rubber plug includes a body 61. A convex block 62 that can block the opening is provided at one end of the body. The outer peripheral wall of the body is fitted and connected to the inner peripheral wall of the water inlet channel. A handle 63 is provided at the other end of the body. If the filter element needs to be used, pull the handle with hand to pull out the soft rubber plug from the water inlet channel. A chute 64 is provided on the body, and a rib 19 that matches the chute is provided in the water inlet channel. More specifically: The water inlet channel is vertically provided in the connector, and the water outlet channel is horizontally provided in the connector. A convex platform 65 that can be embedded in the water outlet channel is provided on the outer periphery of the body. A guiding inclined surface 66 is provided at the upper end of the convex platform, which facilitates the installation of the soft rubber plug into the water inlet channel. A stepped surface 67 is provided at the lower end of the convex platform, so that when the soft rubber plug is placed in the water inlet channel, it can be clamped in the water inlet channel. The opening at the filter element is blocked by a soft rubber plug to prevent the filter material from contacting the air, greatly improving the storage life of the filter element.

[0031] In the present invention: during the water use process, the filter material at the bottom (preferably VC filter material) is continuously consumed, and the pressing plate is continuously compressed downward under the elastic force of the elastomer (the pressing plate is similar to a piston), so that the contact area between the filter material at the bottom and the water is constant, ensuring the stability of the residual chlorine removal effect; when the user does not use the faucet for a long time, under the elastic force of the elastomer, water will not be able to directly enter the cavity where the filter material is located, greatly reducing the problem of the filter element being soaked in water. In the mixing zone: water enters the mixing zone after passing through tiny openings, diluting and mixing the filter material through the filter screen (the high-density filter screen will prevent the filter material from directly entering the water). The external flowing water and the filter material mixed water continuously interact, so that the filter material achieves a continuous and stable slow-release effect.

[0032] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
