Background

Chinese patent application 201811655197.7 discloses a vertical insertion type water passing control device for water purifier waterway control and a water purifier thereof. A insert formula of crossing water controlling means vertically for water purifier waterway control has following advantage: the structure is simple, the occupied area is obviously reduced, the assembly quality is stable, water leakage is not easy to happen, and the efficiency is high; the disassembly and the assembly are easy and labor-saving; the electric control water path switching device which is simple, practical and small in size can be combined to form the electric control water path base structure through the arranged water path electric control valve, the electric control water path switching device is simple, convenient, time-saving and labor-saving to operate, can be operated by pressing keys at any time, can be automatically completed at preset intervals, and can be used for remotely controlling the backflushing cleaning function of each backflushing filter container by a manufacturer with the help of Internet WIFI. The problem that a manual waterway switcher does not have 'dead water' is solved, and the problems that the control backflushing filter containers are few (1-2), the backflushing effect is invisible, the number of connecting pipelines is large and messy, the loading and unloading are complex, the workload is large, the efficiency is low, the water risk is large, and the size is large and the device is not suitable for medium and small models (the size of the machine is small, the device is influenced by the design problems of five structures which are mutually interwoven, and the proper placement position is lacked) due to the lack of an integrated design are solved. However, it is a theoretical concept to change the horizontal water inlet and outlet pipes of the water channel base structure of the traditional water passing control device into vertical pipes which are vertically downward, thereby forming a water channel base structure of the vertical insertion type water passing control device, and to realize some specific functions of the water channel control of the water purifier on this basis, the technical scheme of forming the integrated water channel base structure of the water channel electric control valve by combining the water channel base structures of a plurality of vertical insertion type water passing control devices is adopted. The waterway base of the existing water passing control device is formed by vertically demoulding from top to bottom and then matching with injection molding of a transverse core pulling. On the premise of keeping the structure of the control end of the waterway base, after a horizontal water inlet pipeline and a horizontal water outlet pipeline are changed into vertical downward pipelines, the waterway base including a transverse water channel is manufactured, and the problems of lower cost and higher efficiency of the manufacturing mode are solved. Neither Chinese patent application 201811655197.7 nor the prior art provides specific techniques for manufacturing a total of ten million water control devices on a production scale. The above drawbacks and disadvantages make it difficult to widely popularize the vertically inserted water control device for controlling the water path of the water purifier and the water purifier.

Selecting a related water passing control device to control related water passing pipelines in the filtering channel of the base; the water passing control device is at least one of a waterway electric control valve, a water pressure control switch, a flow sensing device or a concentrated water discharge flow control device, wherein:

the water inlet electric control valve, the water discharge electric control valve, the water return electric control valve and the overflow electric control valve which are one of the waterway electric control valves are all used for controlling the on-off of water passing of the water purifier pipeline.

The high-low water pressure control switch is used as one of the water pressure control switches and is used for controlling a circuit switch through pipeline water pressure change, wherein the low-pressure control switch is provided with a pipeline interface; the high-voltage control switch is provided with an inlet pipeline interface and an outlet pipeline interface.

The flow sensing device is used for driving the related circuit to output a control signal through the flow of the water and accumulating the flow of the water; in the scheme, the flow sensing device also comprises a flow switch which drives the related circuit to output on and off signals only by whether water flows.

And the concentrated water discharge flow control device controls the water discharge flow of a concentrated water discharge port of the reverse osmosis membrane filter liner or the nanofiltration membrane filter liner. The concentrated water discharge flow control device is at least one flow control device of six of a combined electric control valve, an automatic flushing combined valve, an automatic flushing valve, an accumulative flushing valve, an intelligent flushing valve and a waste water proportioner (waste water ratio).

The water flow control components are conventional in the prior art, and it is not described that all of the water flow control components are necessarily adopted in the present application. As to which water passing control components need to be configured in the water purifier provided with the microfiltration membrane, the ultrafiltration membrane, the reverse osmosis membrane filter liner or the nanofiltration membrane filter liner, the water passing control components need to be configured according to the specific needs of various types of machines and connected with corresponding water passing pipelines, and the water passing control components belong to the common knowledge in the field. The function and principle of the common water control part and the connected water pipeline are not explained in the scheme.

The present disclosure describes various embodiments with reference to figures 1-5:
