Description

Technical Field

[0001] The present invention relates to the technical field of faucet valve cores, and particularly to a valve core and a water outlet device. Background Art

[0002] Conventional induction faucets generally add sensors such as infrared outside the conventional valve core and require a mechanical switch to control the on-off of the main water supply, resulting in the need to set up components such as control boxes and water pipes under the washbasin, with a relatively complex structure; and when there is a problem with the circuit, the faucet cannot be manually discharged.

[0003] Existing manual-automatic dual-purpose faucets include both mechanical switch-controlled water discharge (i.e., manual water discharge) and induction water discharge (i.e., automatic water discharge) functions, and a mechanical switch (i.e., a handle) can be used to adjust the cold and hot water mixing ratio (hereinafter referred to as water temperature) of manual water discharge and automatic water discharge: when the handle is swung to the closed state, the water path of manual water discharge is cut off, and at this time, turning the handle can adjust the water temperature of automatic water discharge; when the handle is swung to the open state, the water path of manual water discharge is opened, and at this time, turning the handle can adjust the water temperature of manual water discharge.

[0004] The problems existing in the following structure are that the rotation of the handle actually controls the cold and hot water mixing ratio at the water inlet end of the valve core, that is, the water temperatures of manual and automatic water discharges are adjusted together and are not independent. For example, in a certain scenario, when the user adjusts the water temperature to a good habit when using automatic water discharge, if the user has used manual water discharge and adjusted the water temperature before using automatic water discharge next time, the water temperature needs to be adjusted again when using automatic water discharge next time, resulting in poor user experience; and after adjusting the water temperature, the handle needs to be held at the existing rotation angle to not affect the water temperature of automatic water discharge, and cannot be reset to the center position, which does not conform to the usage habits of some users. Summary of the Invention

[0058] The present invention discloses a valve core, which includes a housing 1, a stationary plate 2, a moving plate group, a bracket 3 and a lever 4;

[0059] The housing 1 is provided with an installation cavity 111, and one end of the installation cavity 111 is provided with a first inlet 112, a second inlet 113, a first outlet 114 and a second outlet 115;

[0060] The stationary plate 2, the moving plate group and the bracket 3 are sequentially fitted in the installation cavity 111 along the direction from one end to the other end of the installation cavity 111;

[0061] The movable plate group includes a first movable plate 5, a second movable plate 6, a first dial 7 and a second dial 8; the first movable plate 5 is coaxially connected to the first dial 7, the second movable plate 6 is coaxially connected to the second dial 8 and movably fits between the first movable plate 5 and the first dial 7; a first limiting mechanism is provided between the first dial 7 and the housing 1; a second limiting mechanism is provided between the second dial 8 and the bracket 3;

[0062] The middle part of the lever 4 is coaxially connected to the bracket 3 and can swing relatively, and one end of the lever 4 is transmission-connected to the moving plate group;

[0063] When the lever 4 is swung to the open state, the first limiting mechanism and the second limiting mechanism are in the unlocked state, the first inlet 112 and the second inlet 113 are connected with the first outlet 114, and are not connected with the second outlet 115. The lever 4 is rotated to adjust the relative position of the first moving plate 5 and the static plate 2, thereby adjusting the mixed water ratio of the first inlet 112, the second inlet 113 and the first outlet 114;

[0064] When the lever 4 swings to the closed state, the first limiting mechanism and the second limiting mechanism are in a locked state, the first inlet 112, the second inlet 113 are connected to the second outlet 115, and are not connected to the first outlet 114; the lever 4 is rotated to adjust the relative angle between the second movable plate 6 and the first movable plate 5, thereby adjusting the mixed water ratio of the first inlet 112, the second inlet 113 and the second outlet 115.

[0065] refer to Figures 1 to 3 Shown is a specific embodiment of the present invention.

[0066] The shell 1 includes a main body 11 and a cover 12; the main body 11 is provided with the above-mentioned installation cavity 111, and one end thereof is provided with the above-mentioned first inlet 112, second inlet 113, first outlet 114 and second outlet 115; the cover 12 is snap-connected to the other end of the main body 11, and is provided with a mounting hole 121 for the bracket 3 to cooperate with.

[0067] The above-mentioned static plate 2, first moving plate 5 and second moving plate 6 are all ceramic plates, which have the advantages of high wear resistance, high sealing performance and long service life.

[0068] The first limiting mechanism comprises a boss 122 arranged in the mounting cavity 111 (i.e., the inner side of the cover body 12), and a guide groove 71 arranged on the surface of the first dial 7, and the guide groove 71 is arranged along the radial direction of the first dial 7; the boss 122 is movably matched between the two ends of the guide groove 71 when the lever 4 swings; when the lever 4 swings to the open state, the boss 122 is located at the outer end of the guide groove 71, and the lever 4 is rotated to make the movable plate group swing along the radial direction of the housing 1 with the boss 122 as the fulcrum, thereby adjusting the relative position of the first movable plate 5 and the static plate 2, so as to adjust the mixed water ratio of the first inlet 112, the second inlet 113 and the first outlet 114. When the lever 4 swings to the closed state, the boss 122 is located at the inner end of the guide groove 71, and when the lever 4 is rotated, the first dial 7 and the first movable plate 5 do not rotate, that is, when the lever 4 is in the closed state, the first movable plate 5 cannot be adjusted, and only the second movable plate 6 can be adjusted.

[0069] Furthermore, a first protrusion 123 is further provided in the installation cavity 111, and a boss 122 is provided on the first protrusion 123; the bracket 3 is provided with a first notch 31; the first protrusion 123 is engaged in the first notch 31 as the bracket 3 rotates, and the boss 122 is passed through the first notch 31 and engaged in the guide groove 71. Since the position of the first protrusion 123 is fixed, the rotation range of the bracket 3 is limited under the cooperation of the first protrusion 123 and the first notch 31, thereby limiting the angle range when the user rotates the lever 4 (i.e., the handle of the water outlet device).

[0070] The first dial 7 is provided with an active cavity 72 for the second movable plate 6 and the second dial 8 to movably cooperate, and the active cavity 72 is provided with a through hole 73; the second dial 8 is provided with a boss 81 matching the through hole 73, and the boss 81 is penetrated by the through hole 73; the second limiting mechanism comprises a second protrusion 32 arranged on the bracket 3, and a second notch 82 arranged on the boss 81, and the arc length of the second notch 82 is greater than the width of the second protrusion 32; when the lever 4 swings to the open state, the second protrusion 32 is separated from the circumferential path of the second notch 82; when the lever 4 swings to the closed state, the second protrusion 32 is located in the second notch 82, and the lever 4 drives the bracket 3 to rotate synchronously, so that the second protrusion 32 abuts against the end of the second notch 82 to drive the second dial 8 and the second movable plate 6 to rotate relative to the first movable plate 5, so as to adjust the mixed water ratio of the first inlet 112, the second inlet 113 and the second outlet 115. A second notch 82 having an arc length greater than the width of the second protrusion 32 is provided on the boss 81, so that when the lever 4 is reset to the center position, the second notch 82 provides movement space for the second protrusion 32, and the movement of the second protrusion 32 no longer pushes the second dial 8 to reset, that is, after the user adjusts the water temperature of the automatic water outlet, the handle of the faucet can be reset without changing the water temperature of the automatic water outlet.

[0071] Furthermore, one end of the shifting lever 4 is a ball head 41, the second dial 8 is provided with a movable groove 83 for the ball head 41 to movably cooperate with, and the second notch 82 is arranged on the end side wall of the movable groove 83. Then, as the shifting lever 4 swings, the ball head 41 rotates in the movable groove 83 and pushes the second dial 8. Also, since both the second dial 8 and the second movable piece 6 are located between the first dial 7 and the first movable piece 5, when the shifting lever 4 swings, it can drive the entire movable piece group to move along the radial plane of the housing 1, thereby changing the relative position between the first movable piece 5 and the static piece 2.

[0072] The edge of the above-mentioned static piece 2 is provided with a first limiting groove 21, and the side wall of the installation cavity 111 is provided with a first limiting block 116. The first limiting block 116 is embedded in the first limiting groove 21 to realize the relative fixation between the static piece 2 and the installation cavity 111; the edge of the mating surface of the first dial 7 and the first movable piece 5 is provided with a second limiting block 74 and a second limiting groove 51, and the second limiting block 74 is embedded in the second limiting groove 51 to realize the coaxial connection between the first dial 7 and the first movable piece 5; the edge of the mating surface of the second dial 8 and the second movable piece 6 is provided with a third limiting block 84 and a third limiting groove 61, and the third limiting block 84 is embedded in the third limiting groove 61 to realize the coaxial connection between the second dial 8 and the second movable piece 6.

[0073] The above-mentioned stationary piece 2 is provided with two first water passing holes 22, a second water passing hole 23 and a third water passing hole 24. The two first water passing holes 22 are respectively communicated with the first inlet 112 and the second inlet 113. The second water passing hole 23 is communicated with the first outlet 114, and the third water passing hole 24 is communicated with the second outlet 115. The above-mentioned first moving piece 5 is provided with two fourth water passing holes 52, a first water passing groove 53 and a fifth water passing hole 54. The two fourth water passing holes 52 are respectively arranged opposite to the two first water passing holes 22. As the first moving piece 5 moves relative to the stationary piece 2, the first water passing groove 53 conducts the first water passing hole 22 and the second water passing hole 23, or the fifth water passing hole 54 is communicated with the third water passing hole 24. The above-mentioned second moving piece 6 is provided with a second water passing groove 62. Two stoppers 63 are arranged in the second water passing groove 62. The fourth water passing hole 52 and the fifth water passing hole 54 are both communicated with the second water passing groove 62. The stoppers 63 change the water passing cross-sectional area of the corresponding fourth water passing hole 52 as the second moving piece 6 rotates relative to the first moving piece 5 to achieve temperature adjustment. Then the water path connection situation formed among the stationary piece 2, the first moving piece 5 and the second moving piece 6 is: the first inlet 112 → the first water passing hole 22 → the first water passing groove 53 → the second water passing hole 23 → the first outlet 114, and the first inlet 112 → the first water passing hole 22 → the fourth water passing hole 52 → the second water passing groove 62 → the fifth water passing hole 54 → the third water passing hole 24 → the second outlet 115. The relative movement between the stationary piece 2 and the moving piece group (i.e., the first moving piece 5) determines that the first water passing groove 53 conducts the first water passing hole 22 and the second water passing hole 23, or the fifth water passing hole 54 conducts the first water passing hole 22, the fourth water passing hole 52, the second water passing groove 62 and the third water passing hole 24, that is, it determines whether the function of manual water outlet or automatic water outlet is turned on. At the same time, the mixing ratio of the manual water outlet (i.e., the water outlet from the first outlet 114) is determined by the relative position between the first moving piece 5 and the stationary piece 2, and the mixing ratio of the automatic water outlet (i.e., the water outlet from the second outlet 115) is determined by the relative angle between the second moving piece 6 and the first moving piece 5.

[0074] Furthermore, the present invention further includes a seal 9 arranged between the end wall of the installation cavity 111 and the stationary piece 2. The seal 9 is respectively provided with a first through hole 91, a second through hole 92 and a third through hole 93 corresponding to the first water passing hole 22, the second water passing hole 23 and the third water passing hole 24 to ensure the sealing at the respective connection positions of the first water passing hole 22 and the first inlet 112 / the second inlet 113, the second water passing hole 23 and the first outlet 114, and the third water passing hole 24 and the second outlet 115.

[0075] The above-mentioned first outlet 114 is arranged at the middle position of the end of the housing 1. The first inlet 112, the second inlet 113 and the second outlet 115 are all arranged on the side of the first outlet 114, and the second outlet 115 is provided with one or more. When there are multiple second outlets 115, the limited space at the end of the housing 1 can be more reasonably utilized in the design and the water output can be ensured.

[0076] Further, the circumferential surface at one end of the above-mentioned housing 1 (i.e., on the main body 11) is provided with a circle of steps 117, and a sealing ring 10 is sleeved on the steps 117. The sealing ring 10 can be used to seal the installation position between the valve core and the water outlet device, ensuring the sealing effect. Compared with designing the seal on the end face of the housing 1 where the first inlet 112, the second inlet 113, etc. are provided, setting the sealing ring 10 on the steps 117 on the circumferential surface of the housing 1 can avoid occupying the design space of the end face of the housing 1, and thus ensure that there is enough space to design the water outlet cross-sectional area of the second outlet 115.

[0077] The above-mentioned bracket 3 is provided with a moving hole 33 for the moving rod 4 to movably cooperate with. A rotating shaft 20 passes through the middle of the moving rod 4 and is rotatably fitted on the side wall of the moving hole 33 to realize the coaxial connection between the moving rod 4 and the bracket 3. The moving rod 4 swings relative to the bracket 3 with the rotating shaft 20 as the axis to drive the moving vane group, and the moving hole 33 provides a swinging space for the moving rod 4.

[0078] The other end of the above-mentioned moving rod 4 is used to install the handle of the water outlet device.

[0079] Reference Figure 10 As shown, the present invention also discloses a water outlet device, which includes the above-mentioned valve core, as well as a solenoid valve 30, a sensor 40 and a tee joint 50; the first outlet 114 is communicated with the tee joint 50; the second outlet 115 is communicated with the tee joint 50 through the solenoid valve 30; the sensor 40 is electrically connected to the solenoid valve 30. This water outlet device only needs to replace the valve core of the present invention on the basis of an ordinary faucet to achieve transformation, realizing that the water outlet device has the multi-functions of manual and automatic water outlet, and the water temperature adjustment of the two does not interfere with each other.

[0080] The above-mentioned sensor 40 is an infrared sensor or a light sensor.

[0081] After applying the present invention to a water outlet device (such as a faucet), the first inlet 112 is communicated with the cold water inlet pipe, the second inlet 113 is communicated with the hot water inlet pipe, the first outlet 114 and the second outlet 115 are respectively communicated with the water outlet end of the faucet (such as the above-mentioned tee joint 50), and the water flowing out of the second outlet 115 passes through the solenoid valve 30; Reference Figure 4 and Figure 9 As shown, the water outlet principle of the present invention is:

[0082] Such as Figure 4 and Figure 5, when the lever 4 swings to the closed state, the lever 4 drives the entire moving blade group to move, changing the relative positions of the first moving blade 5 and the static blade 2, so that the fourth water passing hole 52, the second water passing groove 62, the fifth water passing hole 54 communicate with the third water passing hole 24. Then, the first outlet 114 does not discharge water, and the second outlet 115 discharges water, that is, the product is in the automatic water discharge state, which is controlled by the solenoid valve 30 and the inductor 40. At this time, when the lever 4 rotates to the middle position, the areas of the two fourth water passing holes 52 blocked by the stopper 63 are the same, and cold and hot water are mixed in a ratio of 1:1. After rotating the lever 4 again, the second moving blade 6 will be driven by the bracket 3 to rotate, thereby adjusting the relative position of the second moving blade 6 and the first moving blade 5, and thus changing the water passing cross-sectional areas of the two fourth water passing holes 52, that is, adjusting the cold and hot water mixing ratio in the automatic water discharge state.

[0083] As Figure 6 and Figure 7 , when the lever 4 swings to the open state and is in the middle position, the lever 4 drives the entire moving blade group to move, changing the relative positions of the first moving blade 5 and the static blade 2, so that the first water passing groove 53 conducts the first water passing hole 22 and the second water passing hole 23. Then, the first outlet 114 discharges water, and the second outlet 115 does not discharge water, that is, the product is in the manual water discharge state, which is controlled by the lever 4 (that is, the handle of the water discharge device). At this time, since the lever 4 is in the middle position, cold and hot water are mixed in a ratio of 1:1. As Figure 8 , when the lever 4 swings to the open state and rotates to one extreme angle, the first water passing hole 22 corresponding to the first inlet 112 is completely conducted, and the first water passing hole 22 corresponding to the second inlet 113 is completely closed, realizing full cold water discharge. Figure 9 , when the lever 4 changes to the open state and rotates to the other extreme angle, the first water passing hole 22 corresponding to the first inlet 112 is completely closed, and the first water passing hole 22 corresponding to the second inlet 113 is completely conducted, realizing full cold water discharge.

[0084] Through the above solution, a static blade 2, a first moving blade 5 and a second moving blade 6 are installed in the housing 1 of the present invention as a water path switching mechanism, and a first limiting mechanism is designed between the first dial 7 and the housing 1, and a second limiting mechanism is designed between the second dial 8 and the bracket 3. By different actions of the lever 4, the limiting mechanisms are locked or unlocked, so that different adjustments of the static blade 2 and the moving blade group can be realized under different actions of the lever 4, and further the on-off and mixing water ratio adjustment between the first inlet 112, the second inlet 113 and the first outlet 114 / second outlet 115 are independent of each other, so that the temperature adjustment operations of the manual and automatic water discharges of the water discharge device do not interfere with each other.

[0085] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
