In this embodiment, the booster pump 12 is the power element of the purification flow path 1. When the booster pump 12 is working, the raw water passes through the composite filter element assembly 11, the booster pump 12 and the reverse osmosis assembly 13 in sequence, wherein the composite filter element assembly 11 adopts Filtration and purification, while the reverse osmosis component 13 uses pure water for purification, and the raw water can be prepared as drinking water after being purified by the composite filter element component 11 and the reverse osmosis component 13 in turn. Thinning composite filter element assembly 11, which includes a first composite filter element 111 and a second composite filter element 112, the first composite filter element 111 is connected to the water inlet of the purification flow path 1, the second composite filter element 112 is connected to the booster pump 12, and A solenoid valve 14 is provided on the flow path between the first composite filter element 111 and the second composite filter element 112 . In this embodiment, the composite filter element assembly 11 is two sets of filter elements, and the first composite filter element 111 and the second composite filter element 112 are connected in series, which can effectively ensure the filtration accuracy of the composite filter element assembly 11, while the solenoid valve 14 is a purification system. The water purification switch, its opening and closing state is the same as the working state of the booster pump 12, when the booster pump 12 works, the solenoid valve 14 is opened, and when the booster pump 12 is not working, the solenoid valve 14 is closed. And because each composite filter core has at least two-stage filter structure, thereby making the whole purification flow path 1 form a multi-stage filter form, can effectively guarantee the purification quality of the purification system, and because the first composite filter core 111 and the second composite filter core 112 Both are composite structures, which can save the volume space occupied by the entire purification flow path 1 .
优化上述实施例，第一复合滤芯111与第二复合滤芯112均包括环形滤料外层以及内置于环形滤料外层内的滤料内层，而滤料可以采用PP棉与活性炭，具体地，第一复合滤芯111包括环形PP棉以及内置于环形PP棉内的活性炭，第二复合滤芯112包括环形活性炭以及内置于环形活性炭内的PP棉，在环形滤料外层与对应的滤料内层之间通过密封结构连接，滤料内层贴合于环形滤料外层的内壁上，且在两者的端面位置处采用密封结构密封，密封结构可以采用密封胶等，进而可以避免环形滤料外层与对应的滤料内层之间产生串水，影响过滤后的水质。采用这种结构的复合滤芯，可以有效节省产品空间；复合滤芯采用环筒状结构，可以使得滤料充分利用，节约资源(普通的单级滤芯在实际使用中，往往外层滤料使用过度导致滤芯堵塞，即使中心滤料还很干净也不能继续使用，只能更换新滤芯)，且相对等量滤料来说，采用环状复合结构相比单级滤芯的柱状结构，大大增加了与水的接触面，可以明显提升过滤效率；两级双层的复合滤芯相当于有了四级过滤，相比普通的前置PP棉滤芯、活性炭滤芯、后置PP棉滤芯三级过滤结构，能增强过滤效果。Optimizing the above embodiment, the first composite filter element 111 and the second composite filter element 112 both include an outer layer of annular filter material and an inner layer of filter material built in the outer layer of annular filter material, and the filter material can be PP cotton and activated carbon, specifically , the first composite filter element 111 includes annular PP cotton and activated carbon built in the annular PP cotton, the second composite filter element 112 includes annular activated carbon and PP cotton embedded in the annular activated carbon, and the outer layer of the annular filter material and the corresponding filter material The layers are connected by a sealing structure. The inner layer of the filter material is attached to the inner wall of the outer layer of the annular filter material, and the sealing structure is used to seal the end faces of the two. The sealing structure can use sealant, etc., so as to avoid the ring filter Water flow occurs between the outer layer of the filter material and the corresponding inner layer of the filter material, which affects the filtered water quality. The composite filter element with this structure can effectively save product space; the composite filter element adopts a ring-shaped structure, which can make full use of the filter material and save resources (in the actual use of ordinary single-stage filter elements, the excessive use of the outer filter material often leads to If the filter element is clogged, even if the central filter material is still clean, it cannot continue to be used, and the filter element can only be replaced with a new filter element), and compared with the same amount of filter material, the use of a ring composite structure greatly increases the capacity of the filter element compared with the columnar structure of a single-stage filter element. The contact surface can significantly improve the filtration efficiency; the two-stage and double-layer composite filter element is equivalent to four-stage filtration, compared with the ordinary three-stage filter structure of front PP cotton filter, activated carbon filter, and rear PP cotton filter. filter effect.

When it is detected that the water inlet pressure is low or the water is cut off, a signal can be sent to the control system , it is convenient to control and turn off components such as the solenoid valve 14 and the booster pump 12 to prevent idling operation. A wastewater ratio control structure 131 can be connected to the concentrated water outlet of the reverse osmosis module 13 to control the wastewater ratio of the concentrated water discharged from the reverse osmosis module 13. In order to ensure the drinking water flow at the water outlet valve 232, a 400G reverse permeable membrane, and the waste water ratio of the waste water ratio control structure 131 can be 1000CC. Of course, a concentrated water discharge pipe 132 can be connected to the concentrated water outlet of the reverse osmosis module 13, that is, the concentrated water produced during the reverse osmosis process of the reverse osmosis module 13 can be discharged from the concentrated water discharge pipe 132, then the above-mentioned waste water ratio control structure 131 should be installed on the concentrated water discharge pipe 132. The purification system can also be provided with a concentrated water collection structure.

In this embodiment, the purification system is additionally equipped with a rear activated carbon filter element 16, and the drinking water prepared by the reverse osmosis module 13 first enters the rear activated carbon filter element 16 for filtration, and then is discharged from the purification flow path 1 by the rear activated carbon filter element 16 for drinking by the user. It improves the taste of drinking water. Generally, a water outlet valve or a water storage container is connected to the water outlet of the purification flow path 1, and the drinking water filtered by the rear activated carbon filter element 16 is discharged from the water outlet valve or stored in the water storage container, and the water outlet valve can be a faucet.
