Description

Technical Field

[0001] The invention relates to the technical field of bathroom equipment, and in particular to a valve core structure for a double-control multi-purpose faucet. Background Art

[0002] Faucet is a popular name for water valve, which is used to control the size of water flow and has the effect of saving water. The replacement speed of faucets is very fast, from the old cast iron process to the electroplated knob type, and then to the stainless steel single temperature single control faucet, stainless steel double temperature double control faucet, and kitchen semi-automatic faucet. Now, more and more consumers will consider the material, function, shape and other aspects when purchasing faucets.

[0003] The valve core is a valve part used in a faucet to realize the basic functions of direction control, pressure control or flow control. It is used to control the on and off of the water path in the faucet. The valve core disclosed in the existing invention patent 2020101766530 forms a loop inside the faucet but can only control one water outlet. The solution provided by 2020106206554 is that a valve core controls two water outlets, but it can only control one water outlet when forming a loop function inside the faucet. In order to solve the above problems, in the patent of a dual-control multi-purpose faucet with application number 202010809359.9, since the faucet valve core has two water outlets and a hot and cold water connecting loop, the "zero cold water" function can be realized. However, since the third through hole, the fourth through hole position, the third fan-shaped groove, and the fourth arc groove of the faucet are respectively located within the range of 45 degrees above and below the vertical axis or the horizontal axis, the hole position in the valve core of the same standard specification is reduced, and the flow is insufficient.

[0040] A limiting column 21 is disposed inside the valve core housing 19, and the limiting column 21 is used to limit the movement position of the paddle 10;

[0041] Among them, when the limiting column 21 is located outside the circumference of the end of the movement axis of the paddle 10, the fourth arc-shaped groove 8 of the rotating part 11 covers the first arc-shaped groove 5 and the second arc-shaped groove 6 of the fixed part 12 to form a loop; when the limiting column 21 is located on the left side of the movement axis of the paddle 10, the third fan-shaped groove 7 of the rotating part 11 covers the third through hole 3, the first arc-shaped groove 5, and the second arc-shaped groove 6 to control the opening and closing of the cold and hot mixed water flow of the first water outlet.

[0042] When the limiting column 21 is located outside the circumference of the end of the moving axis of the paddle 10 , the fifth arc-shaped groove 9 of the rotating member 11 covers the first arc-shaped groove 5 and the second arc-shaped groove 6 of the fixing member 12 to form a loop.

[0043] When the limiting column 21 is located on the right side of the movement axis of the paddle 10, the third sector-shaped groove 7 of the rotating member covers the fourth through hole 4, the first arc-shaped groove 5, and the second arc-shaped groove 6 to control the opening and closing of the hot and cold mixed water flow of the second water outlet.

[0044] The paddle 10 is provided with limiting platforms on both sides along the axis of the swing arm 13, and the step surfaces of the limiting platforms (22, 23) correspond to the height of the limiting columns.

[0045] The front side of the fixing member 12 is provided with a first through hole 1 and a second through hole 2 through the vertical axis of the center of the circle, and a third through hole 3 and a fourth through hole 4 are provided through the horizontal axis of the center of the circle, the third through hole 3 is located on the left side of the center of the circle, the fourth through hole 4 is located on the right side of the center of the circle and do not intersect with each other, the first through hole 1 is located above the third through hole 3 and the fourth through hole 4, the second through hole 2 is located below the third through hole 3 and the fourth through hole 4 and do not intersect with each other; the back side of the fixing member 12 is provided with a first arc-shaped groove 5 connecting the first through hole 1 and a second arc-shaped groove 6 connecting the second through hole 2, the outer edges of the first arc-shaped groove 5 and the second arc-shaped groove 6 are located within the circumference of the coverage range of any displacement of the rotating member, the first arc-shaped groove 5 and the second arc-shaped groove 6 are located above and below the vertical axis and do not intersect with each other; the third through hole 3 and the fourth through hole 4 are located on the inner side of the first arc-shaped groove 5 and the second arc-shaped groove 6.

[0046] The rotating member 11 is provided with a third fan-shaped groove 7, and the rotating member 11 is attached to the back side of the fixed member 12. When the circumference of the proximal end of the third fan-shaped groove 7 of the rotating member 11 is tangent to the circumference on the left side of the horizontal axis of the fixed member 12, the third fan-shaped groove 7 covers the third through hole 3, the first arc-shaped groove 5, and the second arc-shaped groove 6; the rotating member 11 is provided with a fourth arc-shaped groove 8, and the rotating member 11 is attached to the back side of the fixed member 12 and the circumference of the distal end of the third fan-shaped groove 7 of the rotating member is tangent to the circumference below the vertical axis of the fixed member, the fourth arc-shaped groove 8 covers the first arc-shaped groove 5 and the second arc-shaped groove 6.

[0047] The rotating member 11 is provided with a fifth arc groove 9. When the rotating member 11 is in contact with the back of the fixed member and the circumference of one side of the far end of the third fan-shaped groove 7 of the rotating member is tangent to the circumference below the vertical axis of the fixed member 12, the fifth arc groove 9 covers the first arc groove 5 and the second arc groove 6.

[0048] The fourth arc groove 8 and the fifth arc groove 9 are located on both sides of the third sector groove 7 and cover the first arc groove and the second arc groove respectively when the limiting column 21 is located outside the circumference of the end of the movement axis of the paddle 10 .

[0049] When the rotating part is in the initial "closed" position of the valve core, the limit column is located outside the circumference of the end of the paddle movement axis; when the rotating part rotates to the "open" position of the valve core, the limit column is located at the inner edge of the limit platform on the side of the paddle movement axis, and the height of the limit column corresponds to the step surface of the limit platform.

When the limit column is at the limit platform on the right side of the paddle, the third fan-shaped groove of the rotating part fits into the fourth through hole, the first arc-shaped groove, and the second arc-shaped groove of the fixed part to move up, down, left and right.

[0053] It should be understood that the “horizontal axis, vertical axis, and motion axis” are virtual axes, and “open” and “close” are relative movements of the parts.

[0054] Figure 1 Schematic diagram of the location of faucet components shown.

[0055] Figure 2 The diagram shows the positions of the first through hole 1, the second through hole 2, the third through hole 3, and the fourth through hole 4 of the valve core.

[0056] FIG. 3(A-1) is a schematic diagram of the hole positions on the back side of the fixing member 12 , and FIG. 3(A-2) is a schematic diagram of the groove positions on the fitting surface of the rotating member 11 .

[0057] Figure 4 A schematic diagram of the left and right limit grooves of the paddle 10 is shown.

[0058] Figure 5 The position diagram of the limiting column 21 of the valve core housing 19 is shown.

[0059] Figure 6 Valve core assembly parts diagram shown.

[0060] Figure 7 As shown in the cross-sectional view of the valve core, when the paddle 10 is in the initial "closed" position of the valve core, the limit post 21 is outside the circumference of the end of the moving axis of the paddle 10. The valve core swing arm 13 can drive the axial rotating member 14 to orbit to this position in the "closed" state. The paddle 10 drives the rotating member 11 in this position. Fig.10 As shown, the third sector groove 7 of the rotating member 11 covers the fixed member 12. The far end circumference of the third sector groove 7 is tangent to the circumference below the vertical axis of the fixed member 12. The third sector groove 7 covers the third through hole 3 and the fourth through hole 4, and the third sector groove 7 does not cover the first arc groove 5; the fourth arc groove 8 and the fifth arc groove 9 cover the first arc groove 5 and the second arc groove 6. The cold water in the first arc groove 5 and the hot water in the second arc groove 6 are connected to form a loop.

[0061] In view of the situation that the distal end circumference of the third sector groove 7 of the rotating member 11 is tangent to the circumference below the vertical axis of the fixing member 12, the third sector groove 7 covers the third through hole 3 and the fourth through hole 4, and the third sector groove 7 does not cover the first arc groove 5, the present invention provides another design scheme with the same principle: Fig.11 The proximal circumference of the third sector groove 7 of the rotating member 11 is tangent to the circumference below the vertical axis of the fixing member 12, and the third sector groove 7 covers the second arc groove 6, and the third sector groove 7 does not cover the third through hole 3 and the fourth through hole 4. The limiting column 21 is provided to limit the paddle 10 to only connect the cold water of the first arc groove 5 and the hot water of the second arc groove 6 in an "open" state to form a circuit.

[0062] The limiting column 21 restricts the paddle 10 to move at this angle only in an "open" or "closed" state so that the positions of the third through hole 3, the fourth through hole 4, the first arc-shaped groove 5, the second arc-shaped groove 6, and the third fan-shaped groove 7 are not limited to the range of 45 degrees with the center of the circle.

[0063] Figure 8 As shown in the initial "closed" position, the swing arm 13 rotates clockwise to drive the paddle 10 to rotate 90 degrees, and the limit column 21 is located at the inner edge of the limit platform 23 on the left side of the paddle movement axis, and the height of the limit column 21 corresponds to the step surface of the limit platform 23. Fig. 9 The third sector groove 7 of the rotating member 11 shown in the figure fits the third through hole 3, the first arc groove 5, and the second arc groove 6 of the fixed member 12 to make up-down and left-right displacements to "open" and "close" the third through hole 3. The proximal circumference of the third sector groove 7 of the rotating member 11 is tangent to the circumference on the left side of the horizontal axis of the fixed member 12, and the third sector groove 7 covers the third through hole 3, the first arc groove 5, and the second arc groove 6. The water from the tap is connected to the first through hole 1 of the valve core through the first water inlet 15 of the faucet, and the first through hole 1 is connected to the first arc groove 5; the hot water from the water heater is connected to the second through hole 2 of the valve core through the second water inlet 16 of the faucet, and the second through hole 2 is connected to the second arc groove 6, and is gathered and redirected into the third through hole 3 through the third sector groove 7, and the third through hole 3 is connected to the first water outlet 17 of the faucet. The hot and cold mixed water flows out from the first water outlet 17. At this time, the fourth arc groove 8 covers the first through hole 1.

[0064] In the initial "closed" position, the swing arm 13 rotates counterclockwise to drive the paddle 10 to rotate 90 degrees, and the limit column 21 is located at the inner edge of the limit platform 22 on the right side of the paddle movement axis. The fourth through hole 4 is "opened" or "closed" in the same principle as above and will not be explained.

[0065] In view of the fact that the paddle is provided with limit platforms on both sides of the swing arm's tossing motion axis, the present invention provides another design scheme with the same principle: Fig.12As shown, the step surface of the limit platform is removed so that the width on both sides of the movement axis of the paddle 10 is smaller than the width at both ends of the movement axis, and the edge of the paddle 10 is tangent to the limit column 21 to control the movement position of the rotating member 11.

[0066] It will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these designs without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

[0067] Those skilled in the art can make corresponding adjustments to the reasonable gaps reserved for "tangent" and "limiting column corresponding to limiting platform step". Using only the fourth arc groove to connect the first arc groove and the second arc groove is within the scope of this technology.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
