It should be noted that, the container is disposed below the connector body 100, and the container is a hot water container, and of course, the container may also be a cold water container, and the check valve 220 needs to be reversely installed at this time, that is, the water inlet end of the check valve 220 is communicated with the first hot water connection port, and the water outlet end of the check valve 220 is communicated with the first cold water inlet 110.

In the embodiment of the present invention, the connector body 100 is further formed with a first faucet intake 112, the first faucet intake 112 and the first cold water inlet 110 are both located on a first side of the connector body 100, and the first hot water connection port is located on a second side of the connector body 100. The first cold water inlet 110 is used for being connected with a first water outlet pipe of the cold water container, the first hot water connection port is used for being connected with a water inlet pipe of the hot water container, and the first water tap water intake 112 is used for being connected with a warm water tap.

In the embodiment of the present invention, fig. 3 illustrates a schematic cross-sectional structure of the water storage device provided in the embodiment of the present invention, and fig. 4 illustrates a schematic side view of the water storage device provided in the embodiment of the present invention, as shown in fig. 3 and 4, the check valve 220 includes a valve body 221 and a valve core 223, a valve body flow channel is formed inside the valve body 221, two ends of the valve body flow channel form a water inlet end and a water outlet end respectively, that is, a lower end of the valve body flow channel forms a water inlet end, and an upper end of the valve body flow channel forms a water outlet end. The inner wall of the valve body flow passage is formed with a first sealing surface 222, and the first sealing surface 222 is horizontally arranged and positioned below the valve core 223. The valve core 223 is arranged in the valve body flow passage, the valve core 223 is made of silica gel, a second sealing surface 224 is formed at the bottom of the valve core 223, and the valve core 223 is suitable for being switched between a closed position and an open position; in the closed position, the first sealing surface 222 is in contact with the second sealing surface 224, the valve body flow passage is blocked, and in the open position, the second sealing surface 224 is separated from the first sealing surface 222, and the valve body flow passage is open.

Fig. 6 illustrates a third schematic side view of the check valve according to the embodiment of the present invention, as shown in fig. 6, the cold water container is located above the connector body 100, the hot water container is located below the connector body 100, water sequentially passes through the cold water container and the first cold water inlet 110 to enter the valve body flow channel under the action of gravity, at this time, the pressure of the cold water is greater than that of the hot water, the water flows upward in the valve body flow channel, the water pushes the valve core 223 to move from the closed position to the open position against the gravity, and since there is no sealing surface above the valve core 223 in sealing fit with the valve core, the cold water continuously flows into the first hot water connection port through the valve body flow channel, and finally enters the hot water container.

Fig. 5 illustrates a second schematic side sectional structure of the check valve according to the embodiment of the present invention, as shown in fig. 5, when hot water is heated, expanded and reflowed, the pressure of cold water is smaller than that of hot water, water flows downwards in the valve body flow channel, and the water presses the valve core 223 downwards, so that the second sealing surface 224 at the bottom of the valve core 223 is attached to the first sealing surface 222, and the valve core 223 blocks the valve body flow channel. And the greater the pressure exerted by the water on the spool 223, the tighter the second sealing surface 224 will be against the first sealing surface 222, the better the tightness. Because the valve core 223 blocks the valve body flow passage, hot water cannot enter the cold water container through the valve body flow passage, so that the temperature of cold water and hot water is prevented from being mixed, the energy consumption is reduced, and the user experience is improved.

Here, the material of the valve body 221 is not limited to silica gel, and may be rubber or other flexible materials.

In the embodiment of the invention, the valve core 223 is a cylinder, the cross section of the valve body flow channel is circular, and a certain gap is arranged between the valve core 223 and the inner wall of the valve body flow channel so as to ensure that the valve core 223 can freely move in the valve body flow channel.

In the embodiment of the present invention, the first sealing surface 222 is an annular plane, the first sealing surface 222 is horizontally disposed, the second sealing surface 224 is a circular plane, the second sealing surface 224 is horizontally disposed, and the outer diameter of the first sealing surface 222 is larger than the diameter of the second sealing surface 224. By having the outer diameter of the first sealing surface 222 greater than the diameter of the second sealing surface 224, in the closed position, even if the position of the spool 223 is displaced by a certain amount, no leakage occurs between the first sealing surface 222 and the second sealing surface 224, reducing the machining precision requirements of the spool 223 and the valve body 221, and reducing the production cost.

In one embodiment of the present invention, fig. 7 illustrates a third schematic side sectional structure of the check valve provided in the embodiment of the present invention, as shown in fig. 7, the second sealing surface 224 is a conical surface, the first sealing surface 222 is an inclined annular surface, and by setting the second sealing surface 224 to be a conical surface, when the valve core 223 is subjected to a larger downward pressure, the second sealing surface 224 is more tightly attached to the first sealing surface 222, and the tightness is better.

In the embodiment of the invention, the concave part 225 is arranged on one side of the valve core 223, which is away from the first sealing surface 222, and the concave part 225 is arranged to enable the interior of the valve core 223 to be hollow, so that the weight of the valve core 223 is reduced, and the buoyancy of the valve core 223 is increased. The upward movement of water requires only a small amount of thrust to the spool 223 to push the spool 223 away from the closed position.

In the embodiment of the invention, a plurality of limiting parts 226 are arranged on the inner wall of the valve body flow passage at intervals, and the limiting parts 226 are positioned on one side of the valve core 223, which is away from the first sealing surface 222, namely, the limiting parts 226 are positioned above the valve core 223. In the open position, a side of the spool 223 facing away from the first sealing surface 222 abuts the stopper 226. Because of the gap between the adjacent two limiting portions 226, water can flow through the gap, and the valve core 223 cannot block the valve body flow passage.

Here, the number of the limiting portions 226 may be two or three or more, and the distances between two adjacent limiting portions 226 may be equal or unequal.

In the embodiment of the present invention, as shown in fig. 1, 3 and 4, the waterway connector further includes a trap 200, a first diversion section 210 and a second diversion section 211 are formed inside the trap 200, a first end of the first diversion section 210 is communicated with the first cold water inlet 110, a second end of the first diversion section 210 is communicated with the water inlet, a first end of the second diversion section 211 is communicated with the first hot water connection port, a second end of the second diversion section 211 is communicated with the water outlet, and the first diversion section 210, the second diversion section 211 and the valve body flow passage together form a U-shaped flow passage. Because the trap 200 is disposed up and down, after the hot water enters the second diversion section 211, the hot water in the second diversion section 211 is under the upper cold water according to the heat conduction principle, so that heat conduction and convection between the cold water and the hot water can be further reduced, and the problem of temperature cross between the cold water and the hot water is solved.

It should be noted that, the first end of the first diversion section 210 is the first end 212 of the water trap, and the first end of the second diversion section 211 is the second end 213 of the water trap.

The volume of the trap 200 should be greater than the product of the volume of the hot water reservoir and the coefficient of expansion of water heating, assuming the volume of the third flow path is Q1, the volume of the hot water reservoir is Q2, and the coefficient of expansion of water heating is K. (as known from physical phenomena, when water is heated to more than 90 degrees, the expansion coefficient of hot water is about 5-10%), so that the capacity Q1 of the third flow channel is larger than or equal to Q2, and of course, in the case of space design, the larger Q1 is, the better, and the preference is that Q1 is larger than or equal to 2, and Q2, K.

The temperature-preventing effect is also related to the shape of the third flow passage, which may be V-shaped, U-shaped or other shapes, preferably a vertically arranged U-shaped flow passage, and in the case that the capacity of water in the hot water container is 1L, the capacity of water in the third flow passage is 80ml, the water temperature in the hot water container is 95 °, and the water inlet temperature is 25 °, as shown in fig. 12, since the trap 200 is not provided in the pipeline, that is, the third flow passage is not present, the water inlet pipe is in a horizontal state at this time, and since the temperature-preventing structure is not provided, the temperature-preventing effect is poor, and the detected water inlet temperature is 53 °. As shown in fig. 13, when the third flow channel may be V-shaped, the first end of the second flow guiding section 211 has an included angle of 45 ° with the vertical direction, and the detected inlet water temperature is 35 °. As shown in fig. 14, when the third flow channel may be U-shaped, the first end of the second flow guiding section 211 is in a vertical state, and the detected inlet water temperature is 26 °. Therefore, when the third flow passage is U-shaped, the trap 200 has the best effect of preventing the cold and hot water from flowing.

In the embodiment of the present invention, as shown in fig. 4, the second end of the first diversion section 210 is connected with the water inlet end in a plugging manner, the second end of the second diversion section 211 is connected with the water outlet end in a plugging manner, and the valve body 221 is connected with the trap 200 through a screw. In order to improve the tightness, the outer peripheral surface of the water inlet end and the outer peripheral surface of the water outlet end are both provided with sealing rings.

The connection between the valve body 221 and the trap 200 is not limited to screw connection, and the valve body 221 and the trap 200 may be integrally formed by snap connection.

It should be noted that, when the connector body 100 is horizontally disposed above the hot water container, the trap 200 is disposed vertically on the side of the connector body 100 near the first faucet intake 112, so that the installation of the connector body 100 is not affected by the trap 200. Of course, the installation position of the trap 200 is not limited to this, and may be provided at other positions of the connector body 100.
