Description

Technical Field

[0001] The invention relates to a valve core and a water outlet device. Background Art

[0002] Some faucets currently on the market have multi-functional water outlets, and are commonly equipped with sparkling water, shower water, mouthwash, etc. For example, the faucet with mouthwash outlet in the existing technical solution is equipped with a conventional single-handle mixing valve core. Since the first water outlet of the faucet is sparkling water or shower water, the use of mouthwash needs to be achieved through the switching mechanism of the water spout. This technical solution often causes inconvenience to users, wastes water resources, and has disadvantages such as complex overall structural design of the faucet. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a valve core that is easy to operate and can simplify the structure of a faucet.

[0004] In order to solve the above technical problems, the present invention provides a valve core, comprising:

[0005] The first water distribution piece;

[0006] The second water-dividing sheet;

[0007] The first water dividing plate includes a first water outlet, a first water inlet, a second water outlet and a second water inlet, and the second water dividing plate includes a first water mixing tank and a second water mixing tank;

[0008] The second water diverter plate is used to move relative to the first water diverter plate and is in an initial state, a first switching state or a second switching state;

[0009] The second water diverter rotates relative to the axis of the first water diverter to change from an initial state to a first switching state, so as to drive the first water mixing tank to connect with the first water outlet and the first water inlet;

[0010] The second water dividing plate slides relative to the first water dividing plate to change from an initial state to a second switching state, so as to drive the second water mixing tank to communicate with the second water outlet and the second water inlet.

[0011] In one embodiment, in the first switching state, the second water diverter rotates relative to the axis of the first water diverter and enables the first water mixing tank to be connected to the first water outlet and the first water inlet in sequence.

[0012] In one embodiment, the first water inlet includes a first cold water inlet and a first hot water inlet.

[0013] In one embodiment, in the first switching state, the second water diverter rotates relative to the axis of the first water diverter and connects the first water outlet, the first cold water inlet and the first hot water inlet to the first mixing tank in sequence.

[0014] In one embodiment, the first water outlet, the first cold water inlet, and the first hot water inlet are arranged at intervals along the rotation direction of the second water dividing plate in the first switching state.

[0015] In one embodiment, in the first switching state, the second water dividing plate rotates to change the overlapping area between the first water mixing tank and the first hot water inlet.

[0016] In one embodiment, the second water inlet includes a second cold water inlet and a second hot water inlet.

[0017] In one embodiment, in the second switching state, the second water dividing plate rotates to change the overlapping areas of the second water mixing tank and the second cold water inlet and the second hot water inlet respectively.

[0018] In one embodiment, the second water outlet is arranged in the middle of the first water dividing plate, and the second hot water inlet and the second cold water inlet are arranged on both sides of the second water outlet and spaced apart along the circumference of the first water dividing plate.

[0019] In one embodiment, the valve core also includes a limiting device, which is configured to limit the sliding of the second water dividing plate relative to the first water dividing plate when the second water dividing plate is in the first switching state, and the limiting device is also configured to limit the rotation range of the second water dividing plate when the second water dividing plate is in the second switching state.

[0020] In one embodiment, the limiting device includes a connecting block that moves synchronously with the second water diversion piece, and the limiting device also includes a first limiting groove and a limiting protruding wall that extend sequentially along the circumference of the second water diversion piece;

[0021] When changing from the initial state to the first switching state, the first end of the connecting block changes from the corresponding first limiting groove to the corresponding limiting protrusion to limit the sliding of the connecting block;

[0022] When changing from the initial state to the second switching state, the first end of the connecting block corresponds to and slides into the first limiting groove, and the first end of the connecting block slides against two end surfaces of the first limiting groove arranged along the circumferential direction.

The second water diverter slides relative to the first water diverter to switch from an initial state to a second switching state, thereby connecting the second water outlet and the second water inlet to the second water diverter. The user can directly rotate the second water diverter to control the connection to the first water outlet, and the user can also slide the second water diverter to connect to the second water outlet, which is convenient and quick, without making complex changes to the faucet structure.

[0029] 2. In the first switching state, the second water diverter rotates relative to the axis of the first water diverter, connecting the first water outlet, the first cold water inlet, and the first hot water inlet to the first mixing tank.

[0054] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] Certain directional terms used in the following description of the drawings, such as "upper," "lower," "left," "right," and other directional terms, are to be understood as having their normal meanings and referring to those directions when the drawings are normally viewed. Unless otherwise indicated, the directional terms used in this specification generally follow the conventional directions understood by those skilled in the art.

[0056] The terms “first”, “second” and the like used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0057] See Figures 1-13 A valve core 100 can be used in a water outlet device, such as a shower head, a shower faucet, a kitchen faucet, etc. The valve core 100 includes a first water diversion plate 10, a second water diversion plate 20, a shell 30, a base 40, and a control mechanism 50. The shell 30 is generally cylindrical and includes two upper and lower openings. The upper opening 31 is necked to define a top abutment ring surface 33 and a connecting ring body 34. The outer peripheral wall of the connecting ring body 34 is arranged with a plurality of vertical stripes 341. The vertical stripes 341 are used to connect to the faucet structure and to limit the rotation of the shell 30. The lower opening 32 of the shell 30 is connected to the base 40. The base 40 is connected to the opening of the shell 30 by a snap. In some simple modifications, the connection between the base 40 and the shell 30 can be connected by gluing. An upper sealing gasket 41 and a lower sealing gasket 42 are respectively arranged on the upper end surface and the lower end surface of the base 40. The upper sealing gasket 41 is used to connect other components of the valve core 100 and prevent water leakage. The structure of the upper sealing gasket 41 is arranged according to the direction of the water channel in the valve core 100. The lower sealing gasket 42 is used to connect other components of the faucet, such as the valve core seat of the faucet, etc., which will not be repeated here. The structure of the lower sealing gasket 42 is arranged according to the direction of the water channel outside the valve core 100.

[0058] The first water-dividing plate 10 and the second water-dividing plate 20 are arranged in the housing 30. The first water-dividing plate 10 is stacked on the base 40. The upper sealing gasket 41 is sealed between the base 40 and the first water-dividing plate 10. A plurality of positioning grooves 11 are recessed into the outer peripheral wall of the first water-dividing plate 10. A plurality of positioning walls 43 extend upward from the periphery of the upper end surface of the base 40. The first water-dividing plate 10 is stacked on the base 40 so that the plurality of positioning grooves 11 are correspondingly connected to the plurality of positioning walls 43. Specifically, there is a one-to-one correspondence between the positioning grooves 11 and the positioning walls 43, and both are four in number and are evenly spaced along the circumference of the base 40. Because the base 40 is connected to the housing 30, the arrangement of the positioning grooves 11 and the positioning walls 43 prevents the first water-dividing plate 10 from rotating relative to the base 40. Therefore, the first water-dividing plate 10 can also be called a water-dividing static plate, or, based on the material of the first water-dividing plate 10, a ceramic static plate.

[0059] The second water diverter plate 20 is stacked between the first water diverter plates 10 and can move relative to the first water diverter plate 10. A plurality of grooves 21 are arranged at intervals on the periphery of the upper end surface of the second water diverter plate 20. The control mechanism 50 links the plurality of grooves 21 and drives the second water diverter plate 20 to move relative to the first water diverter plate 10. Therefore, the second water diverter plate 20 can also be called a water diverter rotor, or, according to the material of the first water diverter plate 10, it can be named a ceramic rotor.

[0060] See Figure 3The control mechanism 50 includes, arranged from bottom to top, a dial 51, a rocker base 52, and a rocker 53. The dial 51 is plate-shaped, with a plurality of protrusions 511 extending downward from its lower end surface. These protrusions 511 are respectively connected to the plurality of grooves 21. The upper end surface of the dial 51 is provided with a connecting block 512 extending radially therefrom and a toggle groove 513 disposed at its center. The rocker base 52 includes a connecting base 521 for connecting to the dial 51 and a rotating cylinder 522 adapted to rotate on the connecting ring body 34. The lower end surface of the connecting base 521 includes a connecting guide groove 5211 corresponding to the connecting block 512. The rocker base 52 also includes a through slot 523 extending through the connecting base 521 and the rotating cylinder 522. The lower end of the rocker 53 is provided with a toggle block 531, and the rocker 53 is connected to the inner wall of the through groove 523 of the rotating cylinder 522 through a cylindrical pin 54. The toggle block 531 extends into the toggle groove 513, and the upper end of the rocker 53 extends out of the shell 30. The rocker 53 is controlled by an external force to drive the rotating cylinder 522 to rotate and drive the dial 51 to slide through the connecting block 512 and the connecting guide groove 5211. When the rotating cylinder 522 rotates, the rocker seat 52 rotates to drive the second water diversion plate 20 to rotate relative to the first water diversion plate 10 through the connecting guide groove 5211, the connecting block 512, the protrusion 511 and the groove 21. When the dial 51 slides, the dial 51 slides to drive the second water diversion plate 20 to slide relative to the first water diversion plate 10 through the protrusion 511 and the groove 21. The upper end surface of the connecting seat 521 abuts against the top abutting annular surface 33 , and an upper wear-resistant pad 55 is arranged between the two.

[0061] See Figure 5The first water divider 10 includes a first water outlet 12, a first water inlet 13, a second water outlet 14 and a second water inlet 15. The first water outlet 12, the first water inlet 13, the second water outlet 14 and the second water inlet 15 are respectively connected to the upper end face and the lower end face of the first water divider 10. The first water inlet 13 includes a first cold water inlet 131 and a first hot water inlet 132, and the second water inlet 15 includes a second cold water inlet 151 and a second hot water inlet 152. The first cold water inlet 131 and the second cold water inlet 151 are respectively connected to cold water, and the first hot water inlet 132 and the second hot water inlet 152 are respectively connected to hot water. The upper end face of the base 40 includes a hot water channel 44, a cold water channel 45 and two water outlet channels 46. The hot water channel 44 is connected to the first hot water inlet 132. and the second hot water inlet 152, the cold water channel 45 is connected to the first cold water inlet 131 and the second cold water inlet 151, the water outlet channel 46 is connected to the first water outlet 12 and the second water outlet 14 respectively, the lower end surface of the base 40 includes a hot water port 47 connected to the hot water channel 44 and connected to hot water, a cold water port 48 connected to the cold water channel 45 and connected to cold water, and two water outlet ports 49 respectively connected to the two water outlet channels 46, the water outlet port 49 can be connected to the water outlet device of the faucet, such as a shower head, a bubbler, etc.

[0062] See Figure 6 The second water diversion piece 20 includes a first mixing trough 22 and a second mixing trough 23. The second mixing trough 23 is located in the middle part of the second water diversion piece 20 and corresponds to the second water outlet 14. The second mixing trough 23 is located in the peripheral part of the second water diversion piece 20 and extends a distance along the circumference of the second water diversion piece 20.

[0063] See Figure 7 At this time, the rocker 53 is not controlled by external force, and the second water diversion plate 20 is in an initial state relative to the first water diversion plate 10. In this initial state, the first mixing water tank 22 and the second mixing water tank 23 are not correspondingly connected to the first water inlet 13 and the second water inlet 15. At this time, the valve core 100 does not discharge water, that is, the initial state is a water-stop state.

[0064] See Figure 8 , showing that the second water diversion plate 20 rotates 45 degrees counterclockwise relative to the axis of the first water diversion plate 10. At this time, one end of the first water mixing tank 22 is connected to the first water outlet 12, and the first water outlet 12 does not discharge water. Figure 9 , showing that the second water-dividing piece 20 is relative to the axis of the first water-dividing piece 10 from Figure 7From the initial state shown in FIG, the second water diverter 20 is rotated 70 degrees counterclockwise to a first switching state. In this first switching state, the second water diverter 20 can drive the first water mixing tank 22 to connect with the first water outlet 12 and the first water inlet 13. Specifically, as shown in FIG. 9 , the first water mixing tank 22 is connected to the first cold water inlet 131, and cold water enters the first water mixing tank 22 from the first cold water inlet 131 and flows out of the first water outlet 12.

[0065] See Figure 10 , showing that the second water-dividing piece 20 is relative to the axis of the first water-dividing piece 10 from Figure 7 In the initial state shown in the figure, it is rotated 90 degrees counterclockwise. At this time, the second water dividing plate 20 drives the first mixing water tank 22 to connect with the first water outlet 12, the first cold water inlet 131 and part of the first hot water inlet 132. At this time, the hot water and cold water in the first hot water inlet 132 and the first cold water inlet 131 are mixed in the first mixing water tank 22 to form warm water of appropriate temperature and flow out from the first water outlet 12.

[0066] Therefore, in the first switching state, the second water diverter 20 rotates relative to the axis of the first water diverter 10, causing the first water mixing tank 22 to sequentially connect to the first water outlet 12 and the first water inlet 13. That is, in the first switching state, the second water diverter 20 rotates relative to the axis of the first water diverter 10, causing the first water mixing tank 22 to sequentially connect to the first water outlet 12, the first cold water inlet 131, and the first hot water inlet 132. Cold water is first connected to the first water outlet 12, followed by warm water.

[0067] See Figure 5 , showing the upper end surface of the first water diverter 10, the first water outlet 12, the first cold water inlet 131, and the first hot water inlet 132 are spaced apart along the rotation direction of the second water diverter 20 in the first switching state. In this embodiment, the first water outlet 12, the first cold water inlet 131, and the first hot water inlet 132 are spaced apart along the counterclockwise rotation direction of the second water diverter 20. The second water outlet 14 is arranged in the middle of the first water diverter 10, and the second hot water inlet 152 and the second cold water inlet 151 are respectively arranged on the left and right sides of the second water outlet 14 and spaced apart along the circumference of the first water diverter 10.

[0068] Figure 9-10 In the first switching state shown, the second water diversion plate 20 rotates to change the overlapping area between the first mixing tank 22 and the first hot water inlet 132. Therefore, the temperature of the warm water flowing out of the first water outlet 12 can be controlled by rotating the angle of the second water diversion plate 20.

[0069] See Figure 11The second water-dividing sheet 20 slides relative to the first water-dividing sheet 10 to Figure 7 The initial state shown changes to a second switching state. In this second switching state, the second water diverter 20 drives the second water mixing tank 23 to connect to the second water outlet 14 and the second water inlet 15. At this time, the second water mixing tank 23 is connected to the second cold water inlet 151 and the second hot water inlet 152. The mixing ratio of the second cold water inlet 151 and the second hot water inlet 152 is the same, so warm water flows out of the second water outlet 14.

[0070] See Figure 12 The second water dividing plate 20 rotates 45 degrees clockwise from the second switching state shown in the figure. At this time, the second mixing tank 23 is only connected to the second hot water inlet 152, and the second water outlet 14 outputs hot water.

[0071] See Figure 13 The second water distribution plate 20 rotates counterclockwise by 45 from the second switching state shown in the figure. At this time, the second mixing tank 23 is only connected to the second cold water inlet 151, and the second water outlet 14 discharges cold water.

[0072] The second water-dividing sheet 20 is Figure 11-13 When rotating in the second switching state shown, i.e., in the second switching state, the second water diverter 20 rotates to change the overlapping area between the second mixing tank 23 and the second cold water inlet 151 and the second hot water inlet 152. At this time, the temperature of the water discharged from the second water outlet 14 can be changed accordingly.

[0073] It should be noted that the second water diverter 20 can also be rotated 45 degrees left and right before sliding to control the connection. During the sliding control, as long as the second mixing tank 23 is connected to the second water inlet 15, the second water diverter 20 can be regarded as entering the second switching state.

[0074] The valve core 100 further includes a limiting device configured to limit the sliding of the second water diverting piece 20 relative to the first water diverting piece 10 when the second water diverting piece 20 is in the first switching state, and further configured to limit the rotation range of the second water diverting piece 20 when the second switching state.

[0075] For example, when the second water diverter 20 is directly rotated counterclockwise by more than 45 degrees from the initial state, the limiting device restricts the second water diverter 20 from sliding further. When the second water diverter 20 slides directly from the initial state or is rotated counterclockwise or clockwise by 45 degrees from the initial state to the second switching state, the second water diverter 20 cannot be rotated counterclockwise by more than 45 degrees to return to the first switching state.

[0076] For details, see Figure 14-22The limiting device 60 includes the connecting block 512 that moves synchronously with the second water-dividing piece 20. The limiting device 60 also includes a first limiting groove 61, a limiting protrusion 62, a second limiting groove 64, and a limiting protrusion 63 that extend sequentially along the circumference of the second water-dividing piece 20. In this embodiment, the first limiting groove 61, the limiting protrusion 62, the second limiting groove 64, and the limiting protrusion 63 are respectively disposed on the inner side of the housing 30, and the connecting seat 521 rotates on the rotating circumferential wall defined by the limiting protrusion 62 and the limiting protrusion 63.

[0077] See Figure 16 , shows a cross-sectional view of the valve core 100 in its initial state. At this point, the first end 5121 of the connecting block 512 is retracted into the connecting guide groove 5211 of the rocker seat 52, while the second end 5122 of the connecting block 512 extends into the second limiting groove 64. The connecting block 512 is restrained by the two circumferential end surfaces of the second limiting groove 64 and rotates within a first rotational range. In this embodiment, the first rotational range is 135 degrees.

[0078] See Figure 17 Combine Figure 8 At this time, one end of the first mixing tank 22 is connected to the first water outlet 12 , and the first end 5121 of the connecting block 512 is about to contact the limiting protruding wall 62 .

[0079] See Figure 18 Combine Figure 9 At this time, the second water diversion plate 20 can drive the first mixing tank 22 to connect the first water outlet 12 and the first water inlet 13, and the first end 5121 of the connecting block 512 changes from the corresponding first limiting groove 61 to the corresponding limiting protrusion 62 to limit the sliding of the connecting block 512. At this time, the second end 5122 of the connecting block 512 corresponds to the bottom wall of the second limiting groove 64 to limit the sliding of the connecting block 512.

[0080] See Figure 19 Combine Figure 10 At this time, the second water diversion plate 20 drives the first mixing water tank 22 to connect with the first water outlet 12, the first cold water inlet 131 and part of the first hot water inlet 132, and the second end 5122 of the connecting block 512 also abuts against one end surface of the second limiting groove 64 to limit the maximum temperature of water that can pass through the first mixing water tank 22, that is, the second end 5121 of the connecting block 512 abuts against the side of the limiting protrusion 63.

[0081] See Figure 20 Combine Figure 11 The second water-dividing sheet 20 slides relative to the first water-dividing sheet 10 to Figure 7The initial state shown is transformed into a second switching state, in which the second water diverter 20 drives the second water mixing tank 23 to connect the second water outlet 14 and the second water inlet 15. At this time, the first end 5121 of the connecting block 512 corresponds to and slides into the first limiting groove 61, and the first end 5121 of the connecting block 512 slides against two end surfaces of the first limiting groove 61 arranged along the circumferential direction.

[0082] See Figure 21 Combine Figure 12 , the second water diversion plate 20 rotates 45 degrees clockwise from the second switching state shown in the figure. At this time, the second mixing tank 23 is only connected to the second hot water inlet 152. At this time, the second water outlet 14 discharges hot water. At this time, the first end 5121 of the connecting block 512 abuts against one end surface of the first limiting groove 61, that is, the first end 5121 of the connecting block 512 abuts against the other side edge of the limiting protrusion 63.

[0083] See Figure 22 Combine Figure 13 , the second water dividing plate 20 rotates counterclockwise by 45 from the second switching state shown in the figure. At this time, the second mixing water tank 23 is only connected to the second cold water inlet 151. At this time, the second water outlet 14 discharges cold water. At this time, the first end 5121 of the connecting block 512 abuts against the other end face of the first limiting groove 61.

[0084] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
