Description

Technical Field

[0001] The present invention relates to the technical field related to faucet valve cores, and particularly to a valve core structure of an electric water heater faucet. Background Art

[0002] A valve core is a valve part that enables a valve body to achieve basic functions such as direction control, pressure control, or flow control through its movement. An electric water heater faucet achieves cold and hot water switching by adjusting the state of the valve core.

[0003] When existing electric water heater faucets are in use, they usually adopt a diaphragm chamber water pressure switch structure. The water flow pressure is used to make electrical contacts connect, thereby starting the water flow heating mechanism. As a result, some water needs to be released before the water flow is heated. Moreover, when the faucet is closed, the water pressure in the diaphragm chamber is likely to remain, leading to overheating. In addition, existing valve core structures usually use a spring assembly to press the static and dynamic valve plates, but the force exerted by the spring assembly is too concentrated, causing impurities in some water flows to enter between the valve plates, affecting the tightness of the combination of the valve plates and resulting in water leakage problems. Summary of the Invention

[0004] In order to fill the market gap, the present invention provides a valve core structure of an electric water heater faucet.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Detailed implementation manner one: Please refer to Figure 1-14 , the present invention provides a technical solution: A valve core structure of an electric water faucet, including:

[0043] The valve handle 1, the lower end of the valve handle 1 extends into the top seat 4, the bottom of the valve handle 1 is movably connected with the dial 5, and the pin shaft 11 is inserted through the valve handle 1;

[0044] The outer housing 2, the bottom end of the outer housing 2 is clamped together with the base 3, and the moving valve plate 6 is screwed and fixed in the middle of the inner wall of the outer housing 2;

[0045] Base 3, on which there are a hot water inlet 31, a cold water inlet 32 and a water outlet 33, and a first clamping block 34 is provided at the top edge of the base 3;

[0046] Top seat 4, which is placed on the dial 5. A limiting groove 41 is provided on the top seat 4, and the top seat 4 is connected to the valve handle 1 through a pin shaft 11;

[0047] Dial 5, on the top surface of which there is an eccentric ring 52, on the bottom surface of which there is a second clamping block 51 connected, and on the circumferential surface of which there is an electrode block 53 welded;

[0048] Moving valve plate 6, on the upper and lower surfaces of which there are respectively a second clamping groove 61 and a water passing groove 62, and on the side wall of which there is an inserted post 63 inserted. The front end of the inserted post 63 is bent to form an inner ring 65 and an outer ring 66;

[0049] Static valve plate 7, on which there are a hot water hole 71, a cold water hole 72 and a water outlet hole 73, and the static valve plate 7 is clamped on the base 3, and a first clamping groove 74 is provided at the edge of the static valve plate 7;

[0050] Limiting ring 8, on the top surface of which there is a sliding groove 81, on the inner and outer circumferential surfaces of which there are power connection rails 82 provided, and in the sliding groove 81 there is a power connection post 86 inserted, and the top end of the power connection post 86 is inserted into the sliding block 83.

[0051] When using the spool structure of this electric water faucet, turn the valve handle 1 to move the dial 5 and the movable valve piece 6. The electrode block 53 is clamped between the sliding blocks 83. At this time, the electric connection pieces 87 on the two sliding blocks 83 are connected to the current through the electrode block 53, starting the heating device installed in the faucet to heat the flowing water. Rotate the valve handle 1 to drive the movable valve piece 6 to rotate accordingly. The position of the water passing groove 62 at the bottom of the movable valve piece 6 changes. When the water passing groove 62 communicates with the hot water hole 71 and the water outlet hole 73, hot water flows into the water passing groove 62 through the hot water inlet 31 and the hot water hole 71, and then flows out of the faucet through the water outlet hole 73 and the water outlet 33. When the water passing groove 62 communicates with the cold water hole 72 and the water outlet hole 73, cold water flows into the water passing groove 62 through the cold water inlet 32 and the cold water hole 72, and then flows out of the faucet through the water outlet hole 73 and the water outlet 33. When the water passing groove 62 communicates with the hot water hole 71, the cold water hole 72 and the water outlet hole 73, the hot water and cold water are mixed in the water passing groove 62 and then flow to the water outlet hole 73, causing the faucet to discharge warm water. Adjust the rotation angle of the valve handle 1 to change the overlapping area between the water passing groove 62 and the hot water hole 71 and the cold water hole 72, achieving the effect of adjusting the water temperature. During the rotation of the valve handle 1, the sliding block 83 moves along the sliding groove 81. When the electrical connection post 86 contacts the electrical connection rail 82, the movable valve piece 6 is in the mixed water or hot water state, and the heating device starts. When the electrical connection post 86 does not contact the electrical connection rail 82, the movable valve piece 6 is in the cold water state, and the heating device is turned off. When the valve handle 1 is turned to make the electrode block 53 withdraw from the sliding block 83, the heating device will also be turned off.

[0052] Specific Embodiment 2: This embodiment is a further limitation of Specific Embodiment 1. As Figure 1 , and Figure 2 shown, the bottom end of the valve handle 1 is clamped into the eccentric ring 52, the top end of the valve handle 1 passes through the limiting groove 41, the pin shaft 11 passes through the valve handle 1 and the top seat 4, the top seat 4 is nested on the top of the outer housing 2, and the top seat 4 abuts between the outer housing 2 and the dial 5. The top seat 4 rotates with the valve handle 1 to make the internal components closely connected.

[0053] Specific Embodiment 3: This embodiment is a further limitation of Specific Embodiment 1. As Figure 3 and Figure 4 shown, the hot water inlet 31, the cold water inlet 32 and the water outlet 33 respectively correspond to the hot water hole 71, the cold water hole 72 and the water outlet hole 73. The first clamping block 34 is clamped with the first clamping groove 74. The radius dimension of the base 3 is larger than the radius dimension of the static valve piece 7. The outer side wall of the static valve piece 7 is in contact with the inner wall of the outer housing 2. The static valve piece 7 is fixed on the base 3. Under the action of the clamping block, the static valve piece 7 and the outer housing 2 remain stationary.

[0054] Specific Embodiment 4: This embodiment is a further limitation of Specific Embodiment 1. The dial 5 and the movable valve plate 6 are clamped together. The second clamping block 51 is adapted to the second clamping groove 61. The radius dimensions of the dial 5 and the movable valve plate 6 are smaller than the radius dimension of the static valve plate 7. The eccentric ring 52 extends into the limiting groove 41. The electrode block 53 is inserted between the sliding blocks 83. The second clamping block 51 and the eccentric ring 52 on the dial 5 are of an integral structure. After the dial 5 moves, the center of the eccentric ring 52 is on the axis of the valve core, which is convenient for restricting the movement track of the electrode block 53.

[0055] Specific Embodiment 5: This embodiment is a further limitation of Specific Embodiment 4. As Figure 5 and Figure 6 shown, insertion slots 64 are symmetrically formed on both sides of the movable valve plate 6. Plug posts 63 are inserted into the insertion slots 64. The front end of the plug post 63 is divided into two parts to form an inner ring 65 and an outer ring 66 respectively. A limiting buckle 67 is fixed at the junction of the plug post 63 and the inner ring 65 and the outer ring 66.

[0056] Specific Embodiment 6: This embodiment is a further limitation of Specific Embodiment 5. The outer ring 66 surrounds the inner ring 65. The tops of the inner ring 65 and the outer ring 66 abut against the bottom surface of the limiting ring 8. A spring is sleeved on the plug post 63 inserted into the insertion slot 64. The inner ring 65 and the outer ring 66 are kept in contact with the outer housing 2 during the movement of the movable valve plate 6 by adjusting the curvature, so that the connection between the valve plates is tight.

[0057] Specific Embodiment 7: This embodiment is a further limitation of Specific Embodiment 1. The arc length of the sliding groove 81 is greater than the arc length of the power connection rail 82. The sliding block 83 has an isosceles triangle structure. A through hole 85 is formed at the tip of the sliding block 83. A connecting rod 84 is welded between the sliding block 83 and the bottom edge of the sliding block 83. A power connection post 86 is fixed on the bottom surface of the sliding block 83. The connecting rod 84 is embedded in the outer housing 2. The shorter power connection rail 82 makes the valve core structure in a disconnected state when releasing cold water, avoiding continuous heating of the heating device and effectively reducing energy consumption.

[0058] Specific Embodiment 8: This embodiment is a further limitation of Specific Embodiment 1. As Figure 8 、 Figure 9 and Figure 10 shown, the width of the electrode block 53 is the same as the width of the gap between the sliding blocks 83. Electric connection pieces 87 are embedded on the opposite surfaces of the two sliding blocks 83. The electric connection pieces 87 are connected through the electrode block 53. The sliding blocks 83 are located above the limiting ring 8, and the electric connection pieces 87 are arranged on the sides of the sliding blocks 83, reducing the probability of the electric connection pieces 87 contacting water in extreme cases.

[0059] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
