in addition, the technical features described below in the different embodiments of the present application may be combined with each other as long as they do not conflict with each other.

as shown in fig. 1 and 2, the present application provides a filter cartridge for a water purifier, comprising:

The number of the housings 1 is such that,

A filter element material 2 located inside the housing;

The water flow channels 3 and 4 are arranged at the end parts of the shell, and self-sealing mechanisms are arranged in the water flow channels 3 and 4.

In general, the water flow passages 3,4 of the water purifier cartridge include water inlet passages 3, respectively, for supplying water to the water purifier cartridge from the outside; and a water outlet passage 4 for delivering the water treated by the purifier cartridge to the outside.

in the present application, the self-sealing mechanism is the key to the filter element of the water purifier of the present application, and is described in detail below. As shown in fig. 2-3, the self-sealing mechanism of the present application includes:

positioning posts 51;

A spring 52 sleeved on the positioning column 51,

a sealing plug 53 disposed in the water flow passage 3,4 of the water purifier filter element, one end of the sealing plug 53 abutting against one end of the spring 51, and an opening of the water flow passage 3,4 of the water purifier filter element being opened and/or closed by displacement of the sealing plug 53 in the water flow passage 3, 4.

in the present application, one end of the spring 52 abuts against an end of the positioning post 51, and the length of the positioning post 51 is smaller than that of the spring 52, which can make the other end of the spring 52 protrude out of the positioning post 51. In one embodiment, the length of the positioning post 51 is smaller than the length of the water flow channel (inlet channel 3 and/or outlet channel 4), and the length of the spring 52 is substantially equal to the length of the water flow channel (inlet channel 3 and/or outlet channel 4), so that one end of the spring extends out of the positioning post with one end of the spring 52 abutting against the end of the positioning post 51.

Be provided with sealing plug 53 in the self sealss mechanism of this application, this sealing plug 53 can be closed under spring 52's effect the opening of the rivers passageway (inhalant canal 3 and/or exhalant canal 4) of water purifier filter core, and can compress under the exogenic action spring 52 and then to thereby the reference column 51 displacement is opened the opening of the rivers passageway (inhalant canal 3 and/or exhalant canal 4) of water purifier filter core. This can be achieved as follows: one end of the sealing plug 53 abuts against one end of the spring 51, so that the sealing plug 53 can compress the spring 52 to displace towards the positioning column 51 under the action of external force so as to open the opening of the water flow channel (the water inlet channel 3 and/or the water outlet channel 4) of the filter element of the water purifier; and, after the external force is removed, the sealing plug 53 can be displaced away from the positioning column 51 under the action of the spring 52, so as to close the opening of the water flow passage (the water inlet passage 3 and/or the water outlet passage 4) of the water purifier filter element. The length of the positioning post 51 determines the displacement distance of the sealing plug 53 in the water flow channel (inlet channel 3 and/or outlet channel 4).

in one embodiment of the application, one end of the sealing plug 53 is concave, and one end of the spring 51 abuts against the concave. This makes it possible to keep the contact position of the spring 52 with the sealing plug 53 constant when the sealing plug 53 is displaced in the water flow passage (the water inlet passage 3 and/or the water outlet passage 4) by the spring 52. Of course, the structure of the sealing plug may be arranged in other ways to achieve the same effect.

In one embodiment, the self-sealing mechanism of the present application further includes a sealing ring 54. The sealing ring 54 is located near the opening of the water flow passage (water inlet passage 3 and/or water outlet passage 4) of the filter element of the water purifier, and the opening of the water flow passage (water inlet passage 3 and/or water outlet passage 4) is closed by the tight contact between the sealing plug 53 and the sealing ring 54. In this embodiment, the sealing plug 53 can be tightly contacted with the sealing ring 54 under the action of the spring 52 so as to close the opening of the water flow passage (the water inlet passage 3 and/or the water outlet passage 4) of the water purifier filter element; meanwhile, the sealing plug 53 can compress the spring 52 under the action of external force to displace towards the positioning column 51, so that the sealing plug 53 is separated from the sealing ring 54, and the opening of the water flow channel (the water inlet channel 3 and/or the water outlet channel 4) of the filter element of the water purifier is opened. In one embodiment, as shown in fig. 2 and 4, a groove is provided near the opening of the inlet channel 3 and/or the outlet channel 4 for receiving the sealing ring 54.

In one embodiment, the self-sealing mechanism of the present application further comprises a position-limiting post 55 located at the periphery of the positioning post 51, and the gap between the position-limiting post 55 and the positioning post 51 is sufficient to allow the spring 52 and the sealing plug 53 to move in the axial direction of the positioning post 51. The positioning of the limiting column 55 can limit the displacement track of the sealing plug in the water flow channel (the water inlet channel 3 and/or the water outlet channel 4), so that the sealing plug can only displace in the gap between the limiting column 55 and the positioning column 51. In one embodiment, the positioning post 51 has a cross-shaped cross-section. In this case, four of the limiting posts 55 are respectively located on the four branches of the cross.

To preferred embodiment, the self sealss mechanism of this application can make the rivers passageway self sealss of filter core to make this filter core rely on the elasticity of spring to make the sealing plug sticiss the opening (can be the sealing washer in an embodiment) of rivers passageway when initial condition, make the filter core isolated inside and outside, avoid the inside external pollution that receives of filter core. When the filter element is connected to the water purifier, the spring can be compressed, and the sealing plug is displaced towards the positioning column, so that the water flow channel is opened, and water flows through; moreover, in the embodiment with the limiting column, the limiting column and the positioning column enable the spring and the sealing plug to move according to the limited track, and the phenomena of blocking and falling cannot occur. When the filter element needs to be replaced and removed from the water purifier, the elastic force of the spring enables the sealing plug to tightly press the opening (which can be a sealing ring in one embodiment) of the water flow channel, so that water in the filter element cannot leak out. The flow channel structure of the filter element can ensure that the flow of the position of the limiting column meets the overall flow requirement of the water purifier while limiting the motion trail of the sealing plug.
