Embodiment 1

[0051] like Figure 5 As shown in the open state, the fixed part and the rotating part are covered figure 1 :

[0052] The rotating handle 1 drives the rotating connecting part 2 and the rotating part 3 to rotate: the outer side of the diversion groove 14 covers the first water inlet hole 7, the second water inlet hole 8, and the center of the diversion groove 14 covers the water outlet hole 9. Hot water state, at this time the communication groove 15 is far away from the first water inlet hole 7 and the second water inlet hole 8 .

[0053] The hot water inlet of the faucet is connected to the first water inlet 10 of the front piece of the valve core, and the first water inlet 10 is connected to the first water inlet hole 7; the cold water inlet is connected to the second water inlet 11 of the front piece of the valve core, and the second water inlet 11 is connected to the second water inlet The water hole 8 and the water flow converge in the diversion groove 14 and then flo...

Embodiment 2

[0055] like Image 6 As shown, the schematic diagram of the cover of the fixed part and the rotating part in the closed state:

[0056] The rotating handle 1 drives the rotating connecting piece 2 and the rotating piece 3 to rotate to: the outer side of the connecting groove 15 covers the first water inlet hole 7 and the second water inlet hole 8. At this time, the center of the diversion groove 14 covers the water outlet hole 9, and the diversion groove 14 The outer side is away from the first water inlet hole 7 and the second water inlet hole 8, and the faucet is in a closed state.

[0057] The hot water inlet of the faucet is connected to the first water inlet 10 of the front piece of the valve core, and the first water inlet 10 is connected to the first water inlet hole 7; the cold water inlet is connected to the second water inlet 11 of the front piece of the valve core, and the second water inlet 11 is connected to the second water inlet In the water hole 8, the water f...

Embodiment 3

[0059] like Figure 7 As shown in the open state, the fixed part and the rotating part are covered figure 2 :

[0060] The rotating handle 1 drives the rotating connecting part 2 and the rotating part 3 to rotate: the outer side of the diversion groove 14 covers the first water inlet hole 7, the center of the diversion groove 14 covers the water outlet hole 9, and the faucet is in the hot water state. At this time, the connecting groove 15 It is away from the first water inlet hole 7 and covers the second water inlet hole 8 .

[0061] The hot water inlet of the faucet is connected to the first water inlet 10 of the front plate of the valve core, and the first water inlet 10 is connected to the first water inlet 7. Hot water passes through the diversion groove 14 and then flows out of the faucet outlet from the water outlet 9 and the water outlet 12.

Abstract

The invention discloses a valve element and a faucet. The valve element comprises a fixing piece and a rotating part; a water outlet hole is formed in the circle center of the back face of the fixing piece, and a first water inlet hole and a second water inlet hole are formed in the positions close to the circumference of the fixing piece; the rotating part forms a flow guide groove corresponding to the water outlet hole, one side of the flow guide groove extends to cover the water inlet hole, the other side, close to the flow guide groove, of the rotating part forms an independent communication groove. According to the valve element and the faucet, a one-way valve is arranged in the water inlet of the valve element, cost is low, a water path unidirectionally flows in the hot water outlet direction, and the defect of cold water series flow is overcome. When the flow guide groove of the valve element is far away from the first water inlet hole and the second water inlet hole, the communication groove of the valve element covers the first water inlet hole and the second water inlet hole, a cold water and hot water communication channel is formed in the valve element when the faucet is closed, a cold water pipe and a hot water pipe are communicated to form a closed loop, on the basis that the water control function of an original faucet is not changed, a water way communicating function is added.

Description

technical field [0001] The invention relates to the technical field of faucet valve cores, in particular to a valve core and a water faucet capable of controlling the water outlet by rotating a handle and connecting to a waterway in a closed state. Background technique [0002] With the development of science and technology and the improvement of people's living standards, there is an increasing demand for zero cold water in water heaters. In the prior art, there are various kinds of zero-cooled water external circulation systems for water heaters. For example, the patent application No. 2020111442400 discloses a faucet, the valve core of which has a one-way channel communicating with the waterway when it is closed. The faucet handle "pulls up" and "presses down" to control the opening and closing of the waterway through the up and down movement of the valve core swing arm. This type of faucet is not suitable for faucets that control the water outlet by rotating the handle...
