Description

Valve core and water outlet device

Technical Field

The invention relates to the technical field of faucet valve cores, in particular to a valve core and a water outlet device.

Background

The conventional induction tap is generally characterized in that an infrared sensor and the like are additionally arranged outside a conventional valve core, and a mechanical switch is required to control the on-off of water supply of a main water path, so that a control box, a water pipe and other parts are required to be arranged under a counter basin, and the structure is relatively complex; and when the circuit goes wrong, the faucet can not manually discharge water.

The existing manual and automatic dual-purpose faucet simultaneously comprises two functions of controlling water outlet (namely manual water outlet) and sensing water outlet (namely automatic water outlet) by a mechanical switch, and can realize the adjustment of the mixing ratio of cold water and hot water (hereinafter referred to as water temperature) of manual water outlet and automatic water outlet by one mechanical switch (namely a handle): when the handle swings to a closed state, the water path for manual water outlet is cut off, and the water temperature for automatic water outlet can be adjusted by rotating the handle; when the handle swings to an open state, the manual water outlet waterway is opened, and the water temperature of the manual water outlet can be adjusted by rotating the handle.

The following structure has problems in that: the rotation of the handle actually controls the mixing ratio of cold water and hot water at the water inlet end of the valve core, namely the water temperature of manual and automatic water outlet is adjusted together and is not independent. For example, in a certain scene, after the habitual water temperature is adjusted when the user uses the automatic water outlet, if the water temperature is adjusted after the user manually discharges water before the user uses the automatic water outlet for the next time, the water temperature needs to be adjusted again when the user uses the automatic water outlet for the next time, and the user experience is poor; in addition, after the water temperature is adjusted, the handle needs to be kept at the existing rotation angle, the water temperature of automatic water outlet cannot be influenced, the handle cannot be reset to the middle position, and the use habit of some users is not met.

the middle part of the deflector rod 4 is coaxially connected with the bracket 3 and can swing relatively, and one end of the deflector rod is in transmission connection with the moving plate group;

when the deflector rod 4 swings to an opening state, the first limiting mechanism and the second limiting mechanism are in an unlocking state, the first inlet 112 and the second inlet 113 are communicated with the first outlet 114 and are not communicated with the second outlet 115, the deflector rod 4 is rotated to adjust the relative positions of the first moving plate 5 and the fixed plate 2, and further the water mixing proportion of the first inlet 112, the second inlet 113 and the first outlet 114 is adjusted;

when the deflector rod 4 swings to the closing state, the first limiting mechanism and the second limiting mechanism are in the locking state, and the first inlet 112 and the second inlet 113 are communicated with the second outlet 115 and are not communicated with the first outlet 114; the shift lever 4 is rotated to adjust the relative angle between the second movable plate 6 and the first movable plate 5, so as to adjust the water mixing ratio of the first inlet 112, the second inlet 113 and the second outlet 115.

Referring to fig. 1-3, a specific embodiment of the present invention is shown.

The housing 1 includes a body 11 and a cover 12; the body 11 is provided with the installation cavity 111, and one end of the installation cavity is provided with the first inlet 112, the second inlet 113, the first outlet 114 and the second outlet 115; the cover 12 is snap-fitted to the other end of the body 11 and is provided with a mounting hole 121 for the bracket 3 to fit.

The stator 2, the first moving plate 5 and the second moving plate 6 are all ceramic plates, and have the advantages of high wear resistance and sealing performance, long service life and the like.

The first limiting mechanism comprises a convex column 122 arranged in the mounting cavity 111 (i.e. the inner side surface of the cover body 12), and a guide groove 71 arranged on the surface of the first dial 7, wherein the guide groove 71 is arranged along the radial direction of the first dial 7; the convex column 122 is movably matched between two ends of the guide groove 71 when the shift lever 4 swings; when the shift lever 4 swings to the open state, the convex column 122 is located at the outer end of the guide groove 71, and the shift lever 4 is rotated to swing the movable blade set along the radial direction of the housing 1 with the convex column 122 as a fulcrum, so as to adjust the relative positions of the first movable blade 5 and the fixed blade 2, thereby adjusting the water mixing ratio of the first inlet 112, the second inlet 113 and the first outlet 114. When the shift lever 4 swings to the closed state, the protruding column 122 is located at the inner end of the guiding slot 71, and when the shift lever 4 is rotated, the first driving plate 7 and the first rotating plate 5 do not rotate, that is, when the shift lever 4 is in the closed state, the first rotating plate 5 cannot be adjusted, and only the second rotating plate 6 can be adjusted.

Furthermore, a first protrusion 123 is further disposed in the mounting cavity 111, and the protruding pillar 122 is disposed on the first protrusion 123; the bracket 3 is provided with a first notch 31; the first protrusion 123 is movably engaged with the first notch 31 along with the rotation of the bracket 3, and the protruding pillar 122 is disposed through the first notch 31 and engaged with the guiding slot 71. Since the position of the first protrusion 123 is fixed, the rotation range of the bracket 3 is limited by the cooperation of the first protrusion 123 and the first notch 31, so as to limit the angle range of the user when rotating the lever 4 (i.e. the handle of the water outlet device).

The first dial 7 is provided with a movable cavity 72 for movably matching the second moving plate 6 and the second dial 8, and the movable cavity 72 is provided with a through hole 73; the second dial 8 is provided with a boss 81 matched with the through hole 73, and the boss 81 is arranged through the through hole 73; the second limiting mechanism comprises a second lug 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 lug 32; when the shift lever 4 swings to the open state, the second bump 32 is separated from the circumferential path of the second notch 82; when the shift lever 4 swings to the closed state, the second protruding block 32 is located in the second notch 82, and the shift lever 4 drives the bracket 3 to rotate synchronously, so that the second protruding block 32 abuts against the end of the second notch 82 to drive the second driving plate 8 and the second moving plate 6 to rotate relative to the first moving plate 5, thereby adjusting the water mixing ratio of the first inlet 112, the second inlet 113 and the second outlet 115. The second notch 82 with the arc length larger than the width of the second protrusion 32 is arranged on the boss 81, so that when the shift lever 4 is reset to the center position, the second notch 82 provides a moving space for the second protrusion 32, the second protrusion 32 is not moved to push the second dial plate 8 to reset any more, 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.

Furthermore, one end of the shift lever 4 is a ball 41, the second dial 8 is provided with a movable groove 83 for movably matching the ball 41, and the second notch 82 is arranged on the side wall of the end part of the movable groove 83. Then, along with the swing of the shift lever 4, the ball 41 rotates in the movable slot 83 and pushes the second dial 8, and because the second dial 8 and the second moving plate 6 are both located between the first dial 7 and the first moving plate 5, the shift lever 4 can drive the entire moving plate set to move along the radial plane of the housing 1 when swinging, so as to change the relative position of the first moving plate 5 and the fixed plate 2.

A first limiting groove 21 is formed in the edge of the stator 2, a first limiting block 116 is arranged on the side wall of the mounting cavity 111, and the first limiting block 116 is embedded in the first limiting groove 21 so as to realize the relative fixation of the stator 2 and the mounting cavity 111; a second limit block 74 and a second limit groove 51 are arranged at the edge of the matching surface of the first driving plate 7 and the first moving plate 5, and the second limit block 74 is embedded in the second limit groove 51 to realize the coaxial connection of the first driving plate 7 and the first moving plate 5; the edge of the matching surface of the second driving plate 8 and the second moving plate 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 of the second driving plate 8 and the second moving plate 6.

as shown in fig. 4 and 5, when the shift lever 4 swings to the closed state, the shift lever 4 drives the moving plate set to move integrally, so that the relative position of the first moving plate 5 and the fixed plate 2 is changed, and the fourth water passing hole 52, the second water passing groove 62, the fifth water passing hole 54 and the third water passing hole 24 are communicated, so that 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, and is controlled by the electromagnetic valve 30 and the sensor 40; when the shift lever 4 rotates to the center position, the areas of the two fourth water through holes 52 blocked by the stopper 63 are the same, and the ratio of the hot water to the cold water is 1: 1, and after the deflector rod 4 is rotated again, the second movable piece 6 is driven to rotate through the bracket 3, and then the relative position of the second movable piece 6 and the first movable piece 5 is adjusted, so that the water passing sectional areas of the two fourth water passing holes 52 are changed, and the cold-hot water mixing ratio in the automatic water outlet state is adjusted.

As shown in fig. 6 and 7, when the shift lever 4 swings to the open state and is located at the center position, the shift lever 4 drives the moving plate set to move integrally, so that the relative position of the first moving plate 5 and the fixed plate 2 is changed, the first water passing groove 53 is communicated with the first water passing hole 22 and the second water passing hole 23, and then the first outlet 114 discharges water, the second outlet 115 does not discharge water, that is, the product is located in a manual water discharge state, and is controlled by the shift lever 4 (that is, the handle of the water discharge device); at this time, because the deflector rod 4 is in the center position, the hot and cold water is mixed in a ratio of 1: 1, mixing in proportion; as shown in fig. 8, when the lever 4 swings to the open state and rotates to a limit angle at one side, the first water passing hole 22 corresponding to the first inlet 112 is completely open, and the first water passing hole 22 corresponding to the second inlet 113 is completely closed, so as to realize the fully-cooled water outlet; as shown in fig. 9, when the lever 4 is moved to the open state and rotated to the other limit 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 opened, so as to realize the fully-cooled water outlet.

Through the scheme, the static piece 2, the first moving piece 5 and the second moving piece 6 are arranged in the shell 1 and used as a water path switching mechanism, the first limiting mechanism is arranged between the first driving plate 7 and the shell 1, the second limiting mechanism is arranged between the second driving plate 8 and the support 3, and the limiting mechanisms are locked or unlocked through different actions of the driving lever 4, so that different adjustment on the static piece 2 and the moving piece group can be realized under different actions of the driving lever 4, the on-off of the first inlet 112, the second inlet 113 and the first outlet 114/the second outlet 115 is realized, and the mutual independence of the adjustment on the water mixing proportion is realized, and the manual and automatic water outlet temperature adjusting operations of the water outlet device are not interfered.
