Problems solved by technology

[0006] The shaft of the impeller passes through the wall of the water pipe. Due to the high pressure of the tap water, it is necessary to keep the shaft rotating while sealing. The manufacturing process and cost are high.
[0007] Another example is that the application number 201621373294.3 discloses the anti-channeling structure installed on the double water inlets. It is difficult to popularize the interface of domestic tap water pipes; this structure is that the double water inlets are equipped with one-way valves, and the two water inlet channels cannot be connected.

Embodiment 1

[0088] Spool 2 is in Figure 5 Position: tap water enters the water heater 14 from the tap water interface 28 and the second water pipe 19, hot water enters the first water pipe 18 from the water outlet port 25, extends through the water pipe to the first water inlet 11 of the faucet, and flows through the internal passage 41 of the body 3 to the first Water inlet outer hole 33. The water flow breaks away the sealing surface 34 of the sealing cap 4, and reaches the first water inlet 16 of the fixed part 9 of the valve core 2 along the diversion groove 35 and the diversion groove 39, and communicates with the second water inlet through the groove 8 of the rotating part 10 17. The second water inlet hole 17 is connected to the second water inlet outer hole 44, passes through the second water inlet 12 of the faucet, and then enters the second water pipe 19. The water flow flows along the hot water outlet direction, forming a water flow loop. The water flow is unidirectionally com...

Embodiment 2

[0091] Faucet 27 handle 1 is in such as Figure 4 position, when hot and cold mixed water flows out or only hot water flows out when turning the handle 1 at this position, the control circuit 24 receives the hot water signal from the Hall sensor 22, and then collects the first temperature sensor 20 and the second temperature sensor 21 water temperature signal. Turn the handle 1 as Figure 5 The groove 8 is connected to the first water inlet tank 6 and the second water inlet tank 7 at the right position, the water circuit forms a closed passage, the water pump 23 is started to work, and the water flow is driven to circulate, and the hot water in the water heater 14 enters the first water pipe 18 from the water outlet port 25 to the faucet The first water inlet 11. The water flows through the internal channel 41 of the body 3 to the first water inlet outer hole 33, enters the first water inlet hole 16 of the fixing part 9 through the one-way valve, communicates with the second...

Embodiment 3

[0095] The Hall sensor 22 starts the water pump to work when the water flow per unit time is less than the set value. Pressurizes the water stream to increase flow and improve shower comfort.

Abstract

The invention discloses a valve core structure, a water faucet and a driving system. The structure includes a rotating part, a fixing part and a bottom plate; Two water inlets and one water outlet, one of the water inlets is provided with a one-way valve; the rotating part is located on the side of the fixing part away from the bottom plate; the rotating part is formed to realize two The groove in which the water inlet is connected and the water outlet is closed; the one-way valve is used to realize the one-way communication between the two water inlets. The spring and sealing cap of the one-way valve are arranged inside the water inlet of the valve core, which is low in cost, makes the waterway flow in one direction along the hot water outlet direction, and solves the shortcoming of cold water cross flow.

Description

technical field [0001] The invention relates to the technical field of faucet valve cores, in particular to a valve core structure with a one-way channel, a water faucet including the valve core structure and a driving system including the water faucet. Background technique [0002] Existing zero-cold water external circulation systems for water heaters, such as application number 202010176653.0 spool, faucet, and circuit fluid supply system with the faucet, discloses an external zero-cold water water heater water circulation system, involving valve cores, faucets, and circuit fluid supply systems . [0003] There is a technical defect that the water circuit connected to the faucet is a two-way flow. When hot water is used at multiple hot water outlets, cold water will flow out from the hot water outlet through the internal channel of the mixed water faucet. [0004] The fluid supply device is only installed separately at the water inlet or outlet of the water heater, and c...
