Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
As shown in fig. 1, a water purifying device for a water dispenser according to a preferred embodiment of the present invention includes a reverse osmosis membrane filter element 1, a post-carbon filter element 2, and a TDS reduction filter element 3, wherein the reverse osmosis membrane filter element 1 has a pure water outlet 11, a waste water outlet 12, and a raw water inlet 13 communicated with raw water, and the raw water inlet 13 is provided with a water inlet pipe for connecting with raw water; the rear carbon filter element 2 comprises a first water inlet 21 communicated with the pure water outlet 11 and a pure water outlet 22 communicated with the water tap 7; fall TDS filter core 3 and set up reverse osmosis membrane filter core 1 reaches between the rearmounted carbon filter 2, including second water inlet 31 and delivery port 32, just second water inlet 31 with 11 intercommunications in pure water outlet, delivery port 32 with first water inlet 21 intercommunication. The TDS reducing filter element 3 is a non-reverse osmosis filter element, and can adopt materials and technologies for reducing TDS, such as electrodialysis, membrane materials, activated carbon, zeolite, resin, ores, new materials and the like.
Purifier for water dispenser based on above-mentioned technical characteristic, through set up between reverse osmosis membrane filter core 1 and rearmounted carbon filter core 2 and fall TDS filter core 3, and the pure water export that will fall TDS filter core and reverse osmosis filter core and rearmounted carbon filter core's first water inlet are linked together, make the pure water after reverse osmosis membrane filter core filters once more through falling TDS filter core 3 and filtering, thereby guaranteed in the full period of drinking water equipment operation, the play water TDS value all is in a lower condition, pipeline pollution has been avoided, guarantee pure water quality of water, guarantee that the user is healthy, also need not discharge "first cup water" simultaneously, water waste has been avoided. The utility model has simple operation, simple structure, good use effect and easy popularization and use.
In this embodiment, the water purifying device for the water dispenser further comprises an electromagnetic three-way valve 4, a third water inlet 23 is arranged on the rear carbon filter element 2, and the electromagnetic three-way valve 4 is respectively communicated with the pure water outlet 11, the second water inlet 31 and the third water inlet 23. Because the problem that the TDS of the pure water end is high can be caused only after the water dispenser is stopped for a period of time, the problem can not be caused if the drinking water equipment works continuously, and the pure water from the pure water outlet 11 does not need to pass through the TDS filter element 3 for filtering, so that the service life of the TDS filter element 3 can be prolonged. By arranging the electromagnetic three-way valve 4, if the pure water needs to be filtered again, the pure water firstly enters the TDS reduction filter element 3, then enters the post-carbon filter element 2 after passing through the electromagnetic three-way valve 4; if the pure water does not need to be filtered again, the pure water directly enters the rear carbon filter element 2 through the other water outlet of the electromagnetic three-way valve 4.
In addition, for the convenience the accurate work of electromagnetic three-way valve 4, electromagnetic three-way valve 4 with be equipped with first TDS probe 5 between the pure water outlet 11, electromagnetic three-way valve 4 with be connected electrically between the first TDS probe 5. The first TDS probe 5 is arranged, so that the pure water from the pure water outlet 11 can be detected in real time, when a user opens the faucet, the first TDS probe 5 detects the TDS of the water, and if the TDS exceeds a set value, an electronic control system gives an instruction to the electromagnetic three-way valve 4, so that a water path is filtered by the TDS-reducing filter element 3; if the TDS value of the effluent is lower than or equal to a set value, the electromagnetic three-way valve 4 enables the pure water coming out of the pure water outlet 11 to directly enter the post-carbon filter element 2.
In this embodiment, a water outlet pipe 6 is arranged on the purified water outlet 22, one end of the water outlet pipe 6, which is far away from the purified water outlet 22, is used for connecting the water faucet 7, and a second TDS probe 8 is arranged on the water outlet pipe 6. An indicator light can also be arranged at the same time, and the indicator light is electrically connected with the second TDS probe 8. Through setting up second TDS probe 8 can further detect the purity of the water that end user used, if filter core filter effect descends and leads to the aquatic TDS when high on the fly, the pilot lamp can remind the user, avoids the user to drink the water of high TDS by mistake and influences healthily, has further improved the security.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
