Description

Technical Field

[0001] This utility model relates to a valve core controlled by a single button. Background Technology

[0002] Most valve cores on the market require the main body for installation. However, the depth of the installation position within the main body may vary depending on the product model. This may result in the valve core being unable to be connected to the control key after installation, requiring the use of different valve cores. If all components of the valve core need to be manufactured by creating molds, it will greatly increase production costs. In addition, existing valve cores generally have two control ends, one for flow and one for on / off. Both of these controls are performed in two different ways, and the structure is also complex. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a valve core controlled by a single button.

[0004] This utility model is achieved through the following technical solution:

[0005] A single-button controlled valve core includes a body with an inlet and an outlet. A rotating cylinder is housed within the body, and a water passage adapted to the inlet is provided on the side wall of the rotating cylinder. The overlapping portion of the water passage and the inlet changes as the rotating cylinder rotates relative to the body. A cooperating stator and rotor are also housed within the rotating cylinder. The stator and rotor are axially movable relative to the rotating cylinder, and the rotor is rotatable relative to the rotating cylinder. A first spring is provided between the rotor and the body. A connecting member capable of blocking the outlet is also provided within the body. The connecting member has a water passage hole and an outlet hole, forming a water passage cavity with the body. The water passage cavity communicates with the water passage hole and the outlet hole. A push rod is also included, one end of which is axially movable with the rotor, and the push rod can block the outlet hole.

[0006] In this embodiment of the utility model, one end of the rotating drum can be located outside the main body, a guide block is provided on the stator, and a guide groove is provided on the inner peripheral wall of the rotating drum; the stator is provided with a first ratchet, and the rotor is provided with a second ratchet that can cooperate with the first ratchet. The second ratchet can also cooperate with the guide groove. The rotating drum is also provided with a slot located next to the guide groove. The first ratchet can cause the second ratchet to rotate after disengaging from the guide groove, so that the second ratchet abuts against the slot.

[0007] In this embodiment of the utility model, a guide slope is provided on both sides of the slot and between the guide groove. The guide slope can cooperate with the second ratchet so that the second ratchet can be guided into the slot or the guide groove.

[0008] In this embodiment of the utility model, a partition is provided inside the main body, the top rod is sleeved on the partition, the water passage cavity is located below the partition, the stator and rotor are located above the partition, one end of the top rod is located above the partition, and the other end of the top rod is located below the partition. A second spring is also provided between the top of the partition and the top rod, and a third spring is provided between the bottom of the partition and the connecting piece.

[0009] In this embodiment of the invention, the first spring is disposed between the partition and the rotor, and the partition and the top rod are sealed together.

[0025] Referring to the accompanying drawings, a single-button controlled valve core includes a body 10 with an inlet 11 and an outlet 12. A rotating cylinder 20 is disposed within the body. A water passage 21, adapted to the inlet, is provided on the side wall of the rotating cylinder. The overlapping portion of the water passage and the inlet changes as the rotating cylinder rotates relative to the body. That is, rotating the rotating cylinder relative to the body changes the overlapping portion (i.e., the water passage area) of the water passage and the inlet, thereby regulating the flow rate. The water passage can be inclined at the top and straight at the bottom, with the water passage area changing through rotation. A stator 30 and a rotor 40 are also disposed within the rotating cylinder. The stator and rotor can move axially relative to the rotating cylinder, i.e., move up and down as shown in the figure. The rotor can move relative to... The rotor rotates, and the stator can continue to rotate with the rotor. A first spring 41 is provided between the rotor and the main body. The main body is also provided with a connector 50 that can block the water outlet. The connector can be a diaphragm. The connector is provided with a water passage hole 51 and a water outlet hole 52. A water passage cavity 13 is formed between the connector and the main body. The water passage cavity can communicate with the water passage hole and the water outlet hole. It also includes a push rod 60. One end of the push rod can move axially with the rotor. The push rod can block the water outlet hole. The stator can be a control button. The water flow can be adjusted by rotating the stator. By installing the stator, it can drive the rotor to move downward and fix it, realizing the opening and closing of the water flow. At the same time, the water inlet is located on the side of the main body and the water outlet is located on the top of the main body.

[0026] Preferably, one end of the rotating drum can be located outside the main body, a guide block 31 is provided on the stator, and a guide groove 22 is provided on the inner peripheral wall of the rotating drum; the stator is provided with a first ratchet 32, and the rotor is provided with a second ratchet 42 that can cooperate with the first ratchet. The second ratchet can also cooperate with the guide groove. The rotating drum is also provided with a slot 23 located beside the guide groove. The first ratchet can cause the second ratchet to rotate after disengaging from the guide groove, so that the second ratchet abuts against the slot. Guide inclined surfaces 24 are provided on both sides of the slot and between the slot and the guide groove. The guide inclined surfaces can cooperate with the second ratchet to guide the second ratchet into the slot or guide groove. When the valve core is in the water-off state, water flows into the water-passing chamber through the water-passing hole. The push rod blocks the water-passing hole, and the water pressure within the chamber forces the connector to block the outlet, thus shutting off the water flow. At this time, the second ratchet abuts against the slot, and the rotor presses against the push rod, blocking the water-passing hole. Then, by pressing the stator, the rotor passes through the slot. With the cooperation of the two ratchets, the rotor rotates. Under the action of the guide ramp, the second ratchet rotates into the guide groove and moves upward under the action of the first spring, also moving out of the water-passing hole via the push rod. When the water is turned on, the water flows from the water passage cavity and the water outlet to the water outlet. The water pressure in the water passage cavity is relieved, and the water pressure at the water inlet end of the water passage hole lifts the connector, making the water inlet and the water outlet directly connected and in the water passage state. Then, press the stator to drive the rotor to move down along the guide groove. After being pushed away from the guide groove, the two ratchet teeth cooperate to make the rotor rotate, so that the second ratchet tooth is stuck in the slot. At the same time, the push rod is also pressed down and moved, moving the connector down to the water outlet. At the same time, the push rod also blocks the water outlet, and the water flows from the water passage hole to the water passage cavity, realizing the water flow is closed.

[0027] Furthermore, a partition 14 is provided within the main body, the push rod is sleeved on the partition, the water passage cavity is located below the partition, the stator and rotor are located above the partition, one end of the push rod is located above the partition, and the other end is located below the partition. A second spring 61 is also provided between the upper part of the partition and the push rod, allowing it to move upward and disengage from the water outlet. A third spring 53 is provided between the lower part of the partition and the connecting piece. The first spring is located between the partition and the rotor, and the partition and the push rod are sealed together to prevent water from escaping. A connecting ball 70 is also provided between the push rod and the rotor, which increases the distance between the rotor and the push rod, allowing the rotating drum to be made longer. This achieves modularity within the main body, non-standard manufacturing of the rotating drum, and reduces the use of molds. The connecting ball can be a soft ball or a hard ball.

[0028] Furthermore, a stop block 25 is provided at the top of the guide groove, and the guide block can abut against the stop block. Then, the first spring holds the stator and rotor against the rotating cylinder, and the stator and rotor form a switching structure similar to a ballpoint pen. A filter screen 80 is provided on the outer periphery of the main body to cooperate with the water inlet.

[0029] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge.
