Description

Tap water purifier and control valve for tap water purifier
Technical Field
The invention relates to a tap water purifier, in particular to a tap water purifier which can carry out two-stage purification on raw water (or tap water) and can utilize primary purified water to wash a secondary filter element (such as an ultrafiltration filter element). The invention further relates to a control valve for a tap water purifier.
Background
With the increasing enhancement of the living standard and the increasing importance of health, the quality requirements of people on living water are also higher. On the other hand, however, many countries, especially developing countries, are increasingly more and more subject to water pollution as industry and agriculture continue to develop, which inevitably results in tap water sources that are also affected by either light or heavy weight. In addition, the quality of tap water is affected by the external environment and the water supply pipeline. For example, the increase in sand content of the water source of tap water may result in deterioration of the quality of tap water. The lack of cleaning, pipe network aging and the like of the tap water supply pipe network for a long time can also influence the quality of tap water. Therefore, tap water is not suitable for direct drinking in many cases. In order to solve the above-mentioned problems of tap water, various household water purifying apparatuses such as ultrafiltration water purifier, RO membrane water purifier, tap water purifier, etc. are commercially available to purify tap water. Among these water purifying apparatuses, the faucet water purifier is favored by many consumers because of its small size, convenience in installation and removal, capability of automatically purifying tap water under tap water pressure without electric power, and the like. However, existing faucet purifiers also have several drawbacks. First, most existing tap water purifiers utilize a single purification cartridge, for example, only ceramic, activated carbon, or ultrafiltration cartridges, to purify tap water. The tap water purifier using a single ceramic filter element or an activated carbon filter element is not thorough in purification of tap water because of the large aperture of the ceramic filter element or the activated carbon filter element, and the obtained purified water is not suitable for direct drinking. The tap water purifier which utilizes a single ultrafiltration filter element to purify tap water is easy to be blocked and can not be used quickly due to the small aperture of the ultrafiltration filter element. Particularly, under the condition of poor water quality, the ultrafiltration filter element is easy to be blocked.
The Chinese patent application of application No. 201811199228.2 discloses a tap water purifier for purifying tap water by utilizing microfiltration ceramics, activated carbon and ultrafiltration ceramics, wherein when the tap water purifier is used for treating tap water, the microfiltration ceramics are used for carrying out microfiltration on the tap water, then the activated carbon is used for carrying out activated carbon filtration on purified water generated by the microfiltration ceramics, and then the purified water generated by the activated carbon is further filtered by the ultrafiltration ceramics and ultrafiltration purified water is generated. However, the lack of a flushing mechanism for the faucet water purifier disclosed in this patent, and in particular, a mechanism for flushing the ultrafiltration membrane, will result in a significant amount of impurities and microorganisms accumulating on the surface of the ultrafiltration membrane and clogging the ultrafiltration membrane in a short period of time. Even a large number of microorganisms accumulate, which may cause the faucet mounted water purifier provided by the present utility model to become odorous after a short period of use.
The Chinese patent application with the application number of 201220080023.4 discloses a tap water purifier which utilizes ceramics and an ultrafiltration filter core to carry out two-stage purification treatment on tap water, wherein the first-stage filter core of the tap water purifier can carry out primary purification on tap water, and the second-stage filter core of the tap water purifier further purifies purified water generated by the first-stage filter core. However, the faucet water purifier provided by the patent application also lacks a mechanism for cleaning (or flushing) the secondary filter element, resulting in the faucet water purifier provided by the patent application also running off in a short period of time.

Referring to fig. 1 to 13F of the drawings of the specification, a tap water purifier according to an embodiment of the present invention is illustrated, wherein the tap water purifier of the present invention includes a control valve 10 and a filtering device 20, wherein the control valve 10 is provided for controlling the flow of water, such as controlling the supply of raw water (or tap water) to the filtering device 20 and controlling the supply of purified water generated or produced by the treatment of raw water by the filtering device 20.
As shown in fig. 1 to 13F of the drawings, the filtering apparatus 20 of the tap water purifier according to the embodiment of the present invention includes a housing 21, a primary filter element 22 and a secondary filter element 23, wherein the housing 21 forms a first receiving chamber 210, the primary filter element 22 forms a second receiving chamber 220, wherein the primary filter element 22 is disposed in the first receiving chamber 210 of the housing 21, the secondary filter element 23 is disposed in the second receiving chamber 220 of the primary filter element 22, and the housing 21 and the primary filter element 22 form a raw water channel 2101 therebetween, the primary filter element 22 and the secondary filter element 23 form a purified water channel 2201 therebetween (the purified water channel 2201 may be regarded as a part of the second receiving chamber 220), and the secondary filter element 23 has a purified water outlet 2301. Accordingly, since the secondary filter element 23 is disposed in the second receiving chamber 220 of the primary filter element 22, when raw water flows in from the raw water channel 2101 and is treated by the primary filter element 22 under the action of water pressure, purified water generated by the primary filter element 22 can flow to the secondary filter element 23 under the action of water pressure and be treated by the secondary filter element 23 and obtain cleaner secondary purified water, which flows out from the purified water outlet 2301 under the action of water pressure to be supplied. Preferably, the primary filter element 22 is a ceramic filter element, and the secondary filter element 23 is an external pressure type ultrafiltration filter element, wherein an ultrafiltration membrane wire 231 of the secondary filter element 23 is disposed in the second accommodation chamber 220 of the primary filter element 22 such that the water purification passage 2201 is formed between the ultrafiltration membrane wire 231 of the secondary filter element 23 and the primary filter element 22. Thus, the purified water produced by the primary filter element 22 can be further ultrafiltered by the secondary filter element 23 under the influence of the water pressure, thereby obtaining cleaner purified water (or ultrafiltered water). It will be appreciated that the primary filter element may also be a filter element made of other materials, or a composite filter element made of multiple materials, for example, a composite filter element composed of any two or more of ceramic, carbon fiber, PP cotton, and activated carbon particles.
As shown in fig. 1 to 13F of the drawings, the filter device 20 of the tap water purifier according to the embodiment of the present invention has a first communication opening 201, a second communication opening 202 and a third communication opening 203, wherein the first communication opening 201 of the filter device 20 communicates with the raw water channel 2101 of the filter device 20 so that the control valve 10 can supply raw water to the filter device 20 through the first communication opening 201, the second communication opening 202 of the filter device 20 communicates with the purified water channel 2201 so that purified water generated by the treatment of raw water by the primary filter element 22 can flow to a second water outlet 200 of the tap water purifier of the present invention and be supplied to a user under the control of the control valve 10, the third communication opening 203 of the filter device 20 communicates with the purified water outlet 1 of the secondary filter element 23 so that purified water generated by the secondary filter element 23 can flow out through the third communication opening 203 and be supplied to the user 100 through a first water outlet of the tap water purifier of the present invention under the control of the control valve 10. Preferably, the secondary filter element 23 of the filtering device 20 of the tap water purifier of the present invention is an external pressure type ultrafiltration filter element. Accordingly, each ultrafiltration membrane wire 231 of the secondary filter element 23 forms a membrane wire channel 2310, and the membrane wire channels 2310 of the ultrafiltration membrane wires 231 are all communicated with the purified water outlet 2301 of the secondary filter element 23, so that purified water generated by each ultrafiltration membrane wire 231 of the secondary filter element 23 can flow to the third communication opening 203 of the filter device 20 under the action of water pressure.
As shown in fig. 1 to 13F of the drawings, accordingly, when the filter device 20 of the tap water purifier according to the embodiment of the present invention is used for treating raw water, a user can control raw water flowing to the first communication opening 201 of the filter device 20 through the control valve 10, raw water flowing to the raw water channel 2101 of the filter device 20 under the action of water pressure, purified water generated after raw water is treated by the primary filter element 22 under the action of water pressure flows to the purified water channel 2201, at this time, if purified water in the purified water channel 2201 is free to flow through the second communication opening 202 of the filter device 20 under the control of the control valve 10, and purified water generated by the secondary filter element 23 cannot freely flow to the third communication opening 203, purified water generated by the primary filter element 22 will flow out from the second communication opening 202 and be supplied under the action of water pressure. Accordingly, the tap water purifier according to the embodiment of the invention is in a filtering working state. On the other hand, if the purified water in the purified water channel 2201 is not free to flow through the second communication opening 202 of the filter device 20 under the control of the control valve 10, and the purified water generated by the secondary filter element 23 is free to flow to the third communication opening 203, the purified water generated by the primary filter element 22 will be further purified by the secondary filter element 23 under the action of the water pressure, and the purified water generated by the secondary filter element 23 will flow out from the third communication opening 203 and be supplied. Correspondingly, the tap water purifier according to the embodiment of the invention is in an ultrafiltration working state. As shown in fig. 1 to 13F of the drawings, further, the tap water purifier according to the embodiment of the present invention has a raw water supply operation state in which a user can control raw water to directly flow to a raw water outlet through the control valve 10 to be supplied without passing through the filtering device 20 and being purified by the same when the tap water purifier of the present invention is in the raw water supply operation state.
It should be noted that, when the second filter element 23 of the filtering device 20 of the faucet water purifier of the present invention is an external pressure type ultrafiltration filter element, and the purified water generated by the first filter element 22 can freely flow out from the second communication opening 202 of the filtering device 20, the purified water generated by the first filter element 22 flows through the ultrafiltration membrane wire 231 of the second filter element 23 when the purified water generated by the first filter element 22 flows out through the second communication opening 202 of the filtering device 20, so that the ultrafiltration membrane wire 231 of the second filter element 23 is rinsed by the purified water generated by the first filter element 22. In other words, at this time, the filtering device 20 of the faucet water purifier of the present invention allows the purified water generated by the primary filter element 22 to be supplied while further washing the ultrafiltration membrane wire 231 of the secondary filter element 23 with the purified water generated by the primary filter element 22. Those skilled in the art will appreciate that the faucet mounted directly to a tap water faucet is relatively small due to the limited space available for use. When the tap water purifier utilizes an ultrafiltration filter element, particularly an ultrafiltration filter element which takes an ultrafiltration membrane wire as a main filter element, the ultrafiltration filter element is easy to be smelly and can not be used continuously because of the aggregation of tap water impurities, such as microorganisms, attached to the surface of the ultrafiltration membrane wire. The filtering device 20 of the tap water purifier of the present invention allows the purified water generated by the primary filter element 22 to be supplied while further using the purified water generated by the primary filter element 22 to clean the surface of the ultrafiltration membrane wire 231 of the secondary filter element 23, thereby preventing the accumulation of microorganisms and the like in tap water on the secondary filter element 23 and preventing the odor thereof from being generated and thus being unable to be used continuously. In other words, the smart structural design of the filtering device 20 of the tap water purifier solves the problem that the conventional tap water purifier is easy to generate impurity aggregation and can not be discharged in time to cause odor when the water is filtered by using the ultrafiltration filter element (or ultrafiltration membrane wire), so that the ultrafiltration membrane wire 231 of the secondary filter element 23 has better filtering effect and the service life of the secondary filter element 23 is prolonged. More importantly, due to the small volume of the tap water purifier, with the structure of the traditional tap water purifier, when the tap water purifier is used for treating raw water such as tap water by using an ultrafiltration filter element, blockage can occur in a short time. The invention obviously improves the problem that the impurity aggregation can not be discharged in time when the traditional tap water purifier filters water by using the ultrafiltration filter element (or the ultrafiltration membrane wire) when the ultrafiltration membrane wire 231 of the second-stage filter element 23 is used for washing the purified water generated by the first-stage filter element 22, thereby enabling the tap water purifier to filter the water by using the ultrafiltration filter element. The faucet water purifier has the great significance that consumers can get rid of the traditional table-type water purifier with large volume and high price. In addition, since the primary filter element 22 of the faucet water purifier of the present invention is preferably a ceramic filter element, purified water produced by filtration is primarily filtered and purified from raw water, although not suitable for direct drinking, and can be used for washing dishes, washing mouths, etc.

Accordingly, the first partition 242D is disposed between the first water chamber 2401D and the second water chamber 2402D, thereby partitioning the first water chamber 2401D and the second water chamber 2402D.
As shown in fig. 20A to 21E of the drawings, accordingly, when the filtering device 20D of the tap water purifier according to the embodiment of the present invention is used to treat raw water, a user can control raw water to flow to the first communication opening 201 of the filtering device 20D through the control valve 10, at this time, if raw water can freely flow through the second communication opening 202 of the filtering device 20D under the control of the control valve 10, and purified water generated by the primary filter element 22D cannot freely flow to the third communication opening 203, raw water will flow in from the first end 2211D of the ultrafiltration membrane wire 221D, flow out from the second end 2212D of the ultrafiltration membrane wire 221D, and then flow out from the second communication opening 202 and be supplied.

Preferably, the filter device 20 of the faucet mounted water purifier of the present invention employs an external pressure type ultrafiltration cartridge. In other embodiments, the filter assembly 20 of the faucet mounted water purifier of the present invention employs an internal pressure ultrafiltration cartridge. Because the membrane surface area of the receivable internal pressure type ultrafiltration membrane filaments is small at the same ultrafiltration cartridge volume, resulting in a relatively small water flow rate generated by the internal pressure type ultrafiltration cartridge, when the internal pressure type ultrafiltration cartridge is employed, it is required that the ultrafiltration cartridge has a larger outer diameter or is coarser. This results in a larger volume of the internal pressure ultrafiltration cartridge for the same purge water flow.
