Description

Technical Field

[0001] This utility model relates to a float control structure for a drain valve, which is applicable to the drain fittings of a water tank. Background Technology

[0002] One type of existing dual-flush drain valve has a rocker arm positioned above the float assembly. In the first position, the rocker arm pushes against the float assembly, causing it to float upwards. In the second position, the rocker arm moves away from the float assembly, allowing it to float. The rocker arm has a rotation axis perpendicular to the direction of movement of the float assembly (the rocker arm is arranged longitudinally). Therefore, when the float assembly pushes against the rocker arm, it generates a rotational torque. The position of the contact area directly affects the magnitude and direction of the rotational torque applied by the float assembly. This mechanism is highly sensitive to the position of the contact area. If the perpendicular distance between the contact area and the rocker arm axis is short, or if the contact area is located on the side of the rocker arm axis closer to the swing direction, the float assembly risks pushing the rocker arm away. However, the internal space of the drain valve is limited, and the contact area cannot usually be positioned far from the axis. Furthermore, this arrangement of the rocker arm significantly occupies space in the direction of float movement, making this structure difficult to implement in low-profile drain valves. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a float control structure for a drain valve.

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

[0005] A float control structure for a drain valve includes a cooperating body and a float assembly, the float assembly being capable of vertical movement relative to the body. It also includes a button that is movable relative to the body; and a rocker arm that rotates relative to the float assembly, one end of which abuts against the float assembly to limit its upward movement. The button controls the rotation of the rocker arm. The direction of movement of the button and / or the axis of rotation of the rocker arm are parallel to the direction of movement of the float assembly.

[0006] In this embodiment of the utility model, the swing arm can be located above the float assembly, and the lower end of the swing arm is provided with an abutment surface, which can abut and cooperate with the float assembly.

[0007] In this embodiment of the utility model, a partition is provided inside the main body, the middle part of the swing rod can be hinged to the partition, one end of the swing rod can cooperate with a button, pressing the button can drive the swing rod to rotate, and the float assembly can abut against the other end of the swing rod.

[0008] In this embodiment of the utility model, the partition is provided with an opening, the button includes a connecting piece that can pass through the opening from top to bottom, one side of the connecting piece is provided with an inclined surface, one end of the swing rod is provided with a guide block that can cooperate with the inclined surface, and when the button is pressed, the cooperation between the guide block and the inclined surface can drive the swing rod to rotate.

[0009] In this embodiment of the utility model, a connecting hole is provided in the middle of the swing rod, and a connecting screw is provided in the connecting hole. The connecting screw can be engaged with the lower end face of the partition to connect the swing rod to the partition; it also includes a first elastic element, which can be engaged with the swing rod.

[0010] In this embodiment of the utility model, a stop block is provided on the connecting piece located below the partition, and the stop block can abut against the partition on the side of the opening. A second elastic element is provided above the partition and between it and the button.

[0011] This utility model discloses a float control structure for a drain valve, which has the following advantages: 1. The force applied by the float assembly to the rocker arm will not drive the rocker arm to rotate around the rotation axis, meaning the contact surface of the rocker arm can be set at any position without the risk of the float assembly pushing the rocker arm open; 2. The rocker arm is arranged laterally, which basically does not occupy the space in the height direction of the drain valve, meaning this mechanism can also be used on low-profile drain valves. In summary, the structure of this utility model avoids the risk of the rocker arm being pushed open, has fewer restrictions on the shape and arrangement of the rocker arm during product design, and has better versatility, allowing this structure to be used for drain valves of various sizes and heights.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] Referring to the accompanying drawings, a float control structure for a drain valve includes a cooperating body 10 and a float assembly 20. The float assembly can move up and down relative to the body, or in other words, move vertically. It also includes a button 30, which can move relative to the body and can be connected to the body; the button can also be pressed vertically. Furthermore, it includes a rocker arm 40, which is horizontally positioned within the body and rotates relative to the float assembly, i.e., rotates horizontally. One end of the rocker arm abuts against the float assembly to limit its upward movement. In one embodiment, the uppermost end of the float assembly abuts against the lower end of the rocker arm, preventing further upward movement. The button controls the rotation of the rocker arm. The movement direction F1 of the button and / or the axis X of the rocker arm's rotation are parallel to the movement direction F2 of the float assembly. In other words, the directions of movement of the float assembly, the button, and the rocker arm are perpendicular. Furthermore, the abutting relationship between the float assembly and the rocker arm prevents the float assembly from driving the rocker arm to rotate, thus avoiding the rocker arm being pushed open.

[0024] Preferably, the swing arm can be located above the float assembly, and the lower end of the swing arm is provided with an abutment surface 41, which can abut and cooperate with the float assembly. Under normal conditions, the float assembly is kept below the swing arm, thereby limiting the rising position of the float assembly and controlling the drainage.

[0025] Furthermore, a partition 50 is provided inside the main body. The middle part of the swing rod can be hinged to the partition. One end of the swing rod can cooperate with a button. Pressing the button can drive the swing rod to rotate. The float assembly can abut against the other end of the swing rod. In other words, the partition divides the main body into upper and lower parts. The button is located in the direction of the partition. The float assembly is normally located below the partition. When the button is pressed to drive the swing rod to rotate, the swing rod releases the restriction on the float assembly. The float assembly rises under the action of buoyancy to realize the drainage of the water tank.

[0026] Furthermore, the partition is provided with an opening 51, and the button includes a connecting piece 31 that can pass through the opening from top to bottom. One side of the connecting piece is provided with an inclined surface 32, and one end of the swing rod is provided with a guide block 42 that can cooperate with the inclined surface. When the button is pressed, the cooperation between the guide block and the inclined surface can drive the swing rod to rotate, which can release the restriction on the float assembly and start the water tank to drain water. At the same time, another clearance opening 52 can be opened on the partition to allow the float assembly to rise.

[0027] Preferably, the swing arm has a connecting hole 43 in the middle, and a connecting screw 60 is provided in the connecting hole. Of course, a nut or a pin can also be used. The main purpose is to enable the swing arm to rotate relative to the body. The connecting screw can be connected to the lower end face of the partition to connect the swing arm to the partition. It also includes a first elastic element 71, which can be connected to the swing arm. The first elastic element can be a torsion spring. When the button is pressed to reset and rise, the torsion spring can drive the swing arm to reset, so that when the water level in the water tank rises, the float assembly can abut against the bottom of the swing arm. Meanwhile, a stop 33 is provided on the connecting piece located below the partition. The stop can abut against the partition on the side of the opening. A second elastic element 72 is provided between the partition and the button. The second elastic element can be a spring, so that the button can be reset when the force is released. In this way, under the guidance of the inclined surface and the action of the torsion spring, the swing arm is reset. At the same time, the connecting piece on the inclined surface can always contact and cooperate with the swing arm, limiting the swing distance (angle) of the swing arm. Under normal conditions, the swing arm is in the same position and can abut against the float assembly. At the same time, the stop can limit the upward stroke of the button.

[0028] The purpose of this utility model is to provide a control mechanism for a drain valve float, including a float assembly and a rocker arm. The rocker arm has a rotation axis, which is parallel to the direction of movement of the float assembly. When the rocker arm is in a first position, it abuts against the float assembly and floats upward. When the rocker arm is in a second position, it avoids the float assembly, and the float assembly floats upward. The rocker arm moves from the first position to the second position by a button, and returns to the first position from the second position by an elastic element. The rocker arm has an abutting part. When the rocker arm is in the first position, the float assembly abuts against the abutting part of the rocker arm. The abutting part of the rocker arm is a plane, and this plane is perpendicular to the rotation axis of the rocker arm.

[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.
