Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-2, the filter element for a water purifier of the present invention comprises a core cylinder 241 and a filter material 242 disposed inside the core cylinder 241, wherein openings are disposed at two ends of the core cylinder 241, the openings at the two ends are respectively communicated with a water inlet 23 and a water outlet 22 of the water purifier, and a raw water through hole 243 is disposed on a side wall of the core cylinder 241.

The filter element for the faucet water purifier based on the technical characteristics is characterized in that a water outlet cavity is formed between the installed rear core cylinder 241 and the water purifier shell, the water outlet cavity is communicated with the raw water outlet 12 of the water purifier, when pure water is not needed, a pure water path is closed, tap water flows to the filter material 242 through the water inlet, and due to the fact that no pressure difference exists, the tap water cannot penetrate into the filter material 242 after entering, only can flow on the surface of the filter material 242, then flows into the water outlet cavity from the raw water through hole 243, and finally flows out from the raw water outlet 12, when the raw water flows out from the surface of the filter material 242, impurities attached to the surface of the filter material 242 can be taken away, and therefore the filter element.

Referring to fig. 3-4, in the present embodiment, in order to facilitate installation of the filter element 24, a filter base 244 is disposed at a lower end of the filter cylinder 241, a water purifying through hole 245 communicating with the water outlet 22 is disposed on the filter base 244, and the filter base 244 is directly installed in the water outlet 22 during installation. Specifically, the filter base 244 includes a clamping groove 2441 and an installation column 2442, the cartridge 241 is inserted into the clamping groove 1441, the installation column 1442 is inserted into the water outlet 22, and the water purifying through hole 245 is disposed on the installation column 2442. Meanwhile, in order to ensure the sealing performance, sealing rings are arranged between the clamping groove 2441 and the core barrel 241 and between the mounting column 2442 and the water outlet.

In addition, in order to ensure the structural strength of the core barrel 241, the outer wall of the core barrel 241 is provided with reinforcing ribs 246, and the reinforcing ribs 246 are distributed along the circumferential direction of the core barrel 241. Preferably, there are two reinforcing ribs 246, and the two reinforcing ribs 246 are respectively disposed at the upper and lower portions of the core barrel 241.

In this embodiment, the raw water passing holes 243 are plural, and the total area of the raw water passing holes 243 is larger than or equal to the total area of the water inlet 23, so that the raw water can be smoothly discharged, and the impurities washed from the filter medium 242 can be completely discharged, thereby preventing the water purifier from being blocked. Preferably, there are two raw water through holes 243, and the two raw water through holes 243 are disposed opposite to each other.

The following description will be made of the installation and use process of the filter element of the present application, taking a specific faucet water purifier as an example:

referring to fig. 3-4, the faucet water purifier of the present embodiment includes a conversion component 1 and a filter component 2, a purified water outlet 11 and a raw water outlet 12 are disposed at a lower end of the conversion component 1, the raw water outlets 12 are multiple, and the raw water outlets 12 are annularly and uniformly distributed at an outer side of the purified water outlet 11. The upper end of the conversion assembly 1 is rotatably connected to the lower end of the filter assembly 2, so that the purified water outlet 11 or the raw water outlet 12 is communicated with the filter assembly 2;

the filter assembly 2 includes the shell 21, the lower extreme of shell 21 be equipped with the delivery port 22 that the outlet for purified water 11 is linked together, the upper end of shell 21 is equipped with water inlet 23, the inside of shell 21 is equipped with filter core 24, filter core 24 includes a core section of thick bamboo 241 and sets up the inside filter media 242 of a core section of thick bamboo 241, the both ends of a core section of thick bamboo 241 respectively with water inlet 23 reaches delivery port 22 is linked together, a core section of thick bamboo 241 with form out the water cavity between the inner wall of shell 21, go out the water cavity with raw water outlet 12 is linked together, the lateral wall of filter core 24 be equipped with the raw water that goes out the water cavity and is linked together crosses water.

Set up raw water outlet 12 through the lower extreme at conversion subassembly 1, and raw water outlet 12 crosses the inside in water hole 243 and core tube 241 through going out the water cavity and raw water and is linked together, when not needing the pure water, the pure water route is sealed, the running water passes through water inlet flow direction filter media 242, because there is not pressure differential, can not permeate filter media 242 after the running water gets into, only can flow through on filter media 242 surface, then cross water hole 243 inflow play the water cavity from the raw water, flow out from raw water outlet 12 at last, the raw water is when flowing through from filter media 242 surface, can take away the impurity that attaches on filter media 242 surface, thereby play the effect of washing, the water purifier jam has been avoided, the life of water.

The tap water purifier of this embodiment can realize the switching between pure water and the raw water, and realizes the washing to the filter media at the in-process of outflow raw water, and its specific working process is:

(1) purified water: when the gear of the water purifier is adjusted to pure water, the raw water path is closed, the pure water path is conducted, tap water is opened to enter, water flows to the filter material 242, water molecules permeate into the filter material 242 under the action of pressure difference, and become pure water after being collected at the filter material base 244, impurities are attached to the surface of the filter material, and the collected pure water flows out from the outlet of the filter material base 244 and finally flows out from the pure water outlet 11 (the water flow direction please refer to the arrow direction in fig. 3);

(2) raw water: when the raw water was transferred to the water purifier gear, the pure water route was sealed, and the raw water route switches on, opens tap running water and gets into, and rivers flow to filter media 242, because there is not pressure differential, can not permeate filter media 242 after the running water gets into, only can flow through on the filter media 242 surface, then flows out from the raw water hole 243 of filter media 242, passes through in proper order again go out water cavity, conversion component 1, follow at last raw water outlet 12 flows out. Meanwhile, the raw water carries away impurities attached to the surface of the filter medium 242 when flowing over the surface of the filter medium 242, thereby performing a flushing function (see the direction of the arrow in fig. 4).

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
