Abstract
Description
Technical Field
[0001] The utility model relates to a bidirectionally opened valve core component. Background Art
[0002] Showers have become an indispensable part of modern homes, and their functionality and convenience directly affect the user's daily experience. Traditional showers typically include a shower head and a lower faucet. In this type of device, the way the water outlet is switched mainly relies on changes in water pressure. When the user turns on the water outlet switch, water first flows out of the lower faucet. At this time, the faucet is usually equipped with a pin puller. By manually pulling it up, the water flow from the lower faucet will stop, and the upper shower head will start to flow water. Although this design basically meets the needs of users, in actual use, there are problems with the switching process being cumbersome and the user experience being poor.
[0003] To address this issue, a bidirectional valve core has been introduced. This valve core can control the opening and closing of the upper and lower water outlets by rotating in two different directions, simplifying the process of switching between outlets. In a shower device using this valve core, the user simply rotates the valve core to switch the water flow between the head shower and the lower faucet, eliminating the tedious operation of pulling a pin in traditional devices and greatly improving user convenience.
[0004] However, this bidirectional valve core also has some shortcomings in practical application. First, during installation, the upper and lower outlet temperature limits must be adjusted. This adjustment is achieved by installing two thermostatic rings on the valve shaft. These rings abut against fixed blocks on the valve core, controlling the valve core's temperature limits in both directions. Due to the friction between the two thermostatic rings, this friction can cause slight shifts in their relative position during use, affecting the performance of the entire device.

DETAILED DESCRIPTION
[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] See Figure 1-Figure 7 , a two-way opening valve core assembly, the valve core assembly includes a valve core, a first temperature regulating component 2 and a second temperature regulating component 3.
[0030] The valve core includes a valve core body 11, a thermostatic valve shaft 12, a first water outlet and a second water outlet. The thermostatic valve shaft 12 can rotate relative to the valve core body 11 from an initial position along a first rotation direction to adjust the water temperature of the first water outlet. The regulating valve shaft can rotate relative to the valve core body 11 from the initial position along a second rotation direction to adjust the water temperature of the second water outlet. The first rotation direction and the second rotation direction are opposite.
[0031] The valve core body 11 is cylindrical, and the thermostatic valve shaft 12 is rotatably mounted on the upper end of the valve core body 11. The lower end of the valve core body 11 includes a cold water inlet, a hot water inlet, a first water outlet, and a second water outlet. The cold water inlet is used to receive cold water, the hot water inlet is used to receive hot water, and the first water outlet and the second water outlet are connected to a head shower and a hand shower, respectively.
[0032] In this embodiment, the valve core is mounted perpendicularly to the wall, and the thermostatic valve shaft 12 extends directly out of the wall to connect to a thermostatic handle. The thermostatic handle can rotate in a first direction (counterclockwise in this embodiment) or a second direction (clockwise in this embodiment) from the initial position. The two rotation directions correspond to adjusting the outlet water temperature of the first and second outlets, respectively.
[0033] The valve core body 11 includes a circular boss 111, from which the thermostatic valve shaft 12 extends. A fixed block 112 is also fixed to the upper end of the boss 111, extending axially along the valve core. A metal ring 121 is fixedly attached to the outer surface of the thermostatic valve shaft 12, with a movable block 122 formed on the outer side of the metal ring 121.
[0034] The first temperature regulating component 2 includes a first temperature regulating block 21, and the first temperature regulating component 2 is arranged on the temperature regulating valve shaft 12 at an adjustable angle through a first spline structure to adjust the position of the first temperature regulating block 21 relative to the fixed block 112. When the regulating valve shaft rotates along the first rotation direction, the first temperature regulating block 21 can abut against the fixed block 112. Specifically, the first spline structure includes a first external spline 221 provided on the outside of the thermostatic valve shaft 12 and a first internal spline 222 provided on the inner circumferential wall of the first thermostatic member 12. The first thermostatic member 2 is in the shape of a cover, and the inner circumferential wall of the first thermostatic member 2 includes the first internal spline 222. When the first thermostatic member 2 is sleeved on the outside of the first external spline 221, the position of the first thermostatic member 2 relative to the thermostatic valve shaft 12 is fixed. When the position of the first thermostatic member 2 relative to the thermostatic valve shaft 12 needs to be adjusted, the first thermostatic member 2 can be pulled out axially, rotated a certain angle relative to the thermostatic valve shaft 12, and then installed. At this time, the position of the first thermostatic block 21 relative to the fixed block 112 can be adjusted. In this embodiment, when the thermostatic valve shaft 12 rotates counterclockwise, it can drive the first thermostatic block 21 to move closer to or farther away from the fixed block 112. In the initial position, the closer the position of the first temperature regulating block 21 is adjusted to the fixed block 112 , the lower the limit temperature of the water temperature at the first water outlet (because the amplitude of the counterclockwise rotation is smaller).
[0035] The second temperature regulating component 3 includes a second temperature regulating block 31, which is arranged on the valve core body 11 at an adjustable angle through a second spline structure to adjust the position of the second temperature regulating block 31 relative to the movable block 122. When the regulating valve shaft rotates along the second rotation direction, the movable block 122 can abut against the second temperature regulating block 31. Specifically, the second spline structure includes a second external spline 321 disposed outside the circular boss 111 and a second internal spline 322 disposed on the inner circumferential wall of the second thermostat 3. The second thermostat 3 is in the shape of a cover, and the inner circumferential wall of the second thermostat 3 includes the second internal spline 322. When the second thermostat 3 is sleeved outside the second external spline 321, the position of the second thermostat 3 relative to the circular boss 111 is fixed. When the position of the second thermostat 3 relative to the circular boss 111 needs to be adjusted, the second thermostat 3 can be axially pulled out, rotated a certain angle relative to the circular boss 111, and then installed. At this time, the position of the second thermostat block 31 relative to the movable block 122 in the initial position can be adjusted. In this embodiment, when the thermostat valve shaft 12 rotates clockwise, it can drive the movable block 122 closer to or farther away from the second thermostat block 31. In the initial position, the closer the second temperature regulating block 31 is adjusted to the movable block 122 in the initial position, the lower the limit temperature of the water temperature at the second water outlet (because the amplitude of the clockwise rotation is smaller).
[0036] In this embodiment, when in the initial position, the space between the movable block 122 and the fixed block 112 along the first rotational direction forms a first travel space, and the first temperature adjustment block 21 is located in the first travel space. When in the initial position, the space between the movable block 122 and the fixed block 112 along the second rotational direction forms a second travel space, and the second temperature adjustment block 31 is located in the second travel space. The two do not interfere with each other.
[0037] In this embodiment, the outer peripheral wall of the first thermostat 2 is fixedly mounted with the first thermostat block 21. A first limiting block 123 is provided on the thermostat valve shaft 12, and the first thermostat 2 is provided with an arcuate limiting groove 11323 extending along the circumference. The first limiting block 123 is located within the arcuate limiting groove 11323. Therefore, the relative position of the first thermostat 2 to the thermostat valve shaft 12 has two extreme positions. In the initial position, the first thermostat block 21 can correspond to the movable block 122 or to a position halfway between the first formed spaces.
[0038] In this embodiment, the inner circumferential wall of the second thermostat 3 is fixedly mounted with a second thermostat block 31. A second stopper 33 is disposed at the lower end of the second thermostat 3. The valve core body 11 is provided with a circumferentially extending stopper groove 113. In this embodiment, the stopper groove 113 is located below the circular protrusion.
[0039] The first thermostat 2 is sleeved on the thermostat valve shaft 12, and the second thermostat 3 is sleeved on the valve core body 11. The second thermostat 3 includes a central through-hole 34, through which the thermostat valve shaft 12 extends. The first thermostat 2 can be sleeved on the thermostat valve shaft 12 through the central through-hole 34. Therefore, the two thermostats do not interfere with each other when adjusting their positions.
[0040] During adjustment, when in the initial position, the space between the movable block 122 and the fixed block 112 along the first rotation direction forms a first travel space, and the first thermostatic block 21 is located in the first travel space. When in the initial position, the space between the movable block 122 and the fixed block 112 along the second rotation direction forms a second travel space, and the second thermostatic block 31 is located in the second travel space. The first thermostatic block 21 can be adjusted to be located in the first travel space, and when the first thermostatic block 21 rotates counterclockwise with the thermostatic valve shaft 12, the first thermostatic block 21 abuts against the fixed block 112. The second thermostatic block 31 can be adjusted to be located in the second travel space, and when the movable block 122 rotates clockwise with the thermostatic valve shaft 12, the movable block 122 abuts against the second thermostatic block 31.
[0041] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the 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 protection scope of the present invention.
