Description

Technical Field

[0001] This invention relates to the field of drain valve technology, and more specifically to a cylindrical drain valve drive and control device. Background Technology

[0002] Existing dual-stage drainage valves typically achieve two drainage volumes through two drive mechanisms. This is achieved by creating a stroke difference on the buttons. During full drainage, applying force to the full drainage button causes the rocker arm to rotate downwards, pulling the water-stopping mechanism upwards. During this process, water continuously drains from the tank, completing the full drainage. During partial drainage, applying force to the partial drainage button results in a smaller stroke, which only drives the partial drainage mechanism and not the full drainage, thus completing the partial drainage. However, the two sets of button mechanisms with stroke differences require two sets of molds for molding, resulting in a complex structure and high product cost. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a device that locks the half-row counterweight barrel, so that the half-row counterweight barrel only functions as a counterweight when the half-row button is pressed, and does not operate when the full-row button is pressed. This allows for the driving and control of a cylindrical drain valve that can perform both full-row and half-row operations using two sets of buttons with the same structure.

[0004] The solution adopted by the present invention to solve the technical problem is: a cylindrical drain valve drive and control device, including a full drain button, a half drain button, a button bracket and an inner sleeve. The full drain button and the half drain button are both mounted on the button bracket. The button bracket is provided with a rotating swing ring located below the full drain button and the half drain button. A half drain counterweight barrel located below the rotating swing ring is movably mounted on the inner sleeve. A locking mechanism is provided between the rotating swing ring and the half drain counterweight barrel for hooking the half drain counterweight barrel and locking it to prevent it from falling. The rotating swing ring is rotatably mounted on the button bracket so that when the half drain button is pressed down, it drives the rotating swing ring to rotate and release the locking of the half drain counterweight barrel.

[0005] Furthermore, to ensure that the half-row counterweight barrel remains locked and does not fall when the full-row button is pressed, the half-row counterweight barrel only disengages and falls when the half-row button is pressed, thereby increasing the float counterweight and shortening the drainage time to achieve half-row drainage; the locking mechanism includes a swing hook on the rotating swing ring and a hook plate on the half-row counterweight barrel. The swing hook is located on the side of the rotating swing ring near the full-row button, so that the rotating swing ring is tilted upwards on the side near the half-row button, thereby ensuring that when the half-row button is pressed down, it drives the rotating swing ring to rotate and release the lock of the swing hook on the hook plate.

[0006] Furthermore, in order to ensure that the rotating pendulum ring firmly hooks the half-row counterweight barrel, there are two hook plates, which extend outward from both sides of the half-row counterweight barrel. There are two corresponding swing hooks, which extend downward from both sides of the rotating pendulum ring. The swing hooks have openings facing the half-row button side for engaging the hook plates.

[0007] Furthermore, in order to store water to increase the weight of the inner sleeve and shorten the drainage time, the half-row counterweight barrel is provided with a water storage cavity with an upward opening for holding water to increase the weight of the half-row counterweight barrel, and the half-row counterweight barrel is also provided with a buoyancy cavity with a downward opening for driving the half-row counterweight barrel to float back to its original position when the water tank is refilled.

[0008] Furthermore, in order to reduce mold opening costs, full-row buttons and half-row buttons with the same structure are used; the full-row buttons and half-row buttons are formed by the same mold, the full-row buttons are marked with a full-row mark, and the half-row buttons are marked with a half-row mark. The full-row buttons and half-row buttons are centrally symmetrically arranged in the button bracket, and elastic elements for resetting the full-row buttons and half-row buttons are respectively provided below the full-row buttons and half-row buttons in the button bracket.

[0009] Furthermore, to reduce mold opening costs, full-row swing arms and half-row swing arms with the same structure are used; the cylindrical drain valve drive and control device also includes a swing arm assembly for driving the inner sleeve to move upward. The swing arm assembly includes a full-row swing arm and a half-row swing arm made using the same mold. The full-row swing arm and the half-row swing arm are centrally symmetrically mounted in the button bracket. One end of the full-row swing arm and the half-row swing arm are respectively located below the full-row button and the half-row button, and the other end of the full-row swing arm and the half-row swing arm are rotatably connected to the inner sleeve.

[0010] Furthermore, in order to rotatably mount the full-row swing arm and the half-row swing arm on the button bracket; each of the full-row swing arm and the half-row swing arm includes a swing arm seat, a pressing arm for pressing and engaging with the full-row button and the half-row button, and a connecting arm for rotatably connecting with the inner sleeve. The swing arm seat has a U-shaped structure, with the opening of the swing arm seat facing the inner sleeve. The two sides of the swing arm seat are provided with outwardly protruding rotating shaft heads for rotatably mounting on the button bracket. The button bracket is provided with shaft holes for inserting the rotating shaft heads. The pressing arm extends outward from one side of the swing arm seat, and the connecting arm extends outward from the other side of the swing arm seat.

[0011] Furthermore, in order to form a pressing engagement structure for the full row of buttons and the full row of swing arms, and for the half row of buttons and the half row of swing arms, the pressing arms are two in number, extending outward from both sides of the swing arm base. The full row of buttons and the half row of buttons are each provided with pressing steps for pressing engagement with the pressing arms. The full row of buttons and the half row of buttons are each provided with two pressing steps, which are formed by the inner walls on both sides of the full row of buttons and the half row of buttons protruding inward.

[0012] Furthermore, in order to rotatably connect the full-row swing arm and the half-row swing arm to the inner sleeve, there are two connecting arms, which extend outward from both sides of the swing arm seat. The inner sleeve is provided with an extension arm for rotatably connecting with the connecting arms. There are two extension arms corresponding to the full-row swing arm and the half-row swing arm. The extension arms extend radially outward from both sides of the inner sleeve. A rotating shaft is provided on the outer side of the extension arm. The end of the connecting arm is provided with a rotating hole for inserting the rotating shaft.

[0013] Furthermore, to prevent the half-row counterweight barrel from impacting the float and to achieve adjustable drainage volume, a water-stopping component for sealing the drain outlet of the drain valve and a float located above the water-stopping component to delay the descent of the inner sleeve are installed on the lower side of the inner sleeve. A counterweight support is also fixedly installed on the inner sleeve. The counterweight support is located between the half-row counterweight barrel and the float to catch the half-row counterweight barrel when it falls. Both the float and the counterweight support can be adjusted up and down on the inner sleeve to adjust the drainage volume of the water tank.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure and is easy to use. It uses a rotating pendulum ring to fix the half-row counterweight barrel. Because the rotating pendulum ring is tilted upward on the side near the half-row button, when the full-row button is pressed, the full-row button cannot touch the rotating pendulum ring, and the rotating pendulum ring does not move. When the half-row button is pressed, the half-row button touches the rotating pendulum ring, driving the rotating pendulum ring to rotate, causing the pendulum hook to disengage, and the half-row counterweight barrel will fall down, increasing the counterweight of the float, thereby shortening the drainage time and realizing half-drainage. Furthermore, because the present invention uses a rotating pendulum ring, there is no need to make structural differences between the full-row button and the half-row button. The full-row button and the half-row button with the same structure can be formed using a single mold. In addition, the full-row swing arm and the half-row swing arm can also be manufactured using only one mold, which greatly reduces the mold opening cost. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0024] Specific implementation examples: such as Figure 1-6 As shown, this embodiment provides a cylindrical drain valve drive and control device, including a full drain button 1, a half drain button 2, a button bracket 3, and an inner sleeve 4. The full drain button 1 and the half drain button 2 are both mounted on the button bracket 3. The button bracket 3 is provided with a rotating swing ring 5 located below the full drain button 1 and the half drain button 2. The inner sleeve 4 is movably fitted with a half drain counterweight 6 located below the rotating swing ring 5. A locking mechanism is provided between the rotating swing ring 5 and the half drain counterweight 6 to hook the half drain counterweight 6 and lock it to prevent it from falling. The rotating swing ring 5 is rotatably mounted on the button bracket 3 so that when the half drain button 2 is pressed down, the rotating swing ring 5 rotates to release the locking of the half drain counterweight 6.

[0025] In this embodiment, to ensure that the half-row counterweight 6 remains locked and does not fall when the full-row button 1 is pressed, the half-row counterweight 6 only disengages and falls when the half-row button 2 is pressed. This increases the counterweight of the float 13, thereby shortening the drainage time and achieving half-row drainage. The locking mechanism includes a swing hook 501 on the rotating swing ring 5 and a hook plate 601 on the half-row counterweight 6. The swing hook 501 is located on the side of the rotating swing ring 5 near the full-row button 1, so that the center of gravity of the rotating swing ring 5 is close to the side of the full-row button 1, forming a state in which the rotating swing ring 5 is tilted upwards near the side of the half-row button 2, thereby ensuring that when the half-row button 2 is pressed down, it drives the rotating swing ring 5 to rotate and release the lock of the swing hook 501 on the hook plate 601.

[0026] In this embodiment, in order to ensure that the rotating pendulum ring 5 firmly hooks the half-row counterweight barrel 6, there are two hook plates 601, which extend outward from both sides of the half-row counterweight barrel 6 respectively. There are two corresponding pendulum hooks 501, which extend downward from both sides of the rotating pendulum ring 5 respectively. The pendulum hooks 501 have openings facing the half-row button 2 side for engaging the hook plates.

[0027] In this embodiment, in order to store water to increase the weight of the inner sleeve 4 and shorten the drainage time, the half-row counterweight 6 is provided with a water storage cavity 602 with an upward opening for holding water to increase the weight of the half-row counterweight 6. The half-row counterweight 6 is also provided with a buoyancy cavity with a downward opening for driving the half-row counterweight 6 to float back to its original position when the water tank is refilled. The buoyancy cavity is arranged around the outer periphery of the water storage cavity 602.

[0028] In this embodiment, to reduce mold opening costs, full-row buttons 1 and half-row buttons 2 with the same structure are used. The full-row buttons 1 and half-row buttons 2 are formed by the same mold. The full-row buttons 1 are marked with a full-row mark, and the half-row buttons 2 are marked with a half-row mark. The full-row buttons 1 and half-row buttons 2 are centrally symmetrically arranged in the button bracket 3. The button bracket 3 is provided with elastic elements 16 for resetting the full-row buttons 1 and half-row buttons 2 respectively below the full-row buttons 1 and half-row buttons 2.

[0029] In this embodiment, to reduce mold opening costs, full-row swing arms 10 and half-row swing arms 11 with the same structure are used; the cylindrical drain valve drive and control device also includes a swing arm assembly for driving the inner sleeve 4 to move upward. The swing arm assembly includes full-row swing arms 10 and half-row swing arms 11 made by the same mold. The full-row swing arms 10 and half-row swing arms 11 are centrally symmetrically mounted in the button bracket 3. One end of the full-row swing arms 10 and half-row swing arms 11 is located below the full-row button 1 and half-row button 2, respectively, and the other end of the full-row swing arms 10 and half-row swing arms 11 is rotatably connected to the inner sleeve 4.

[0030] In this embodiment, in order to rotatably mount the full-row swing arm 10 and the half-row swing arm 11 on the button bracket 3, both the full-row swing arm 10 and the half-row swing arm 11 include a swing arm seat 7, a pressing arm 8 for pressing and engaging with the full-row button 1 and the half-row button 2, and a connecting arm 9 for rotatably connecting with the inner sleeve 4. The swing arm seat 7 has a U-shaped structure, with the opening of the swing arm seat 7 facing the inner sleeve 4. The two sides of the swing arm seat 7 are provided with outwardly protruding rotating shaft 402 heads for rotatably mounting on the button bracket 3. The button bracket 3 is provided with shaft holes for inserting the rotating shaft 402 heads. The pressing arm 8 extends outward from one side of the swing arm seat 7, and the connecting arm 9 extends outward from the other side of the swing arm seat 7.

[0031] In this embodiment, in order to form a pressing engagement structure between the full row of buttons 1 and the full row of swing arms 10, and between the half row of buttons 2 and the half row of swing arms 11, there are two pressing arms 8. The two pressing arms 8 extend outward from both sides of the swing arm seat 7. The full row of buttons 1 and the half row of buttons 2 are respectively provided with pressing steps 12 for pressing engagement with the pressing arms 8. There are two pressing steps 12 on the full row of buttons 1 and the half row of buttons 2 respectively. The two pressing steps 12 are formed by the inner walls on both sides of the full row of buttons 1 and the half row of buttons 2 protruding inward.

[0032] In this embodiment, in order to rotatably connect the full-row swing arm 10 and the half-row swing arm 11 to the inner sleeve 4, there are two connecting arms 9, which extend outward from both sides of the swing arm seat 7. The inner sleeve 4 is provided with extension arms 401 for rotatably connecting with the connecting arms 9. There are two extension arms 401 to correspond to the full-row swing arm 10 and the half-row swing arm 11. The extension arms 401 extend radially outward from both sides of the inner sleeve 4. The outer side of the extension arm 401 is provided with a rotating shaft 402. The end of the connecting arm 9 is provided with a rotating hole 901 for inserting the rotating shaft 402.

[0033] In this embodiment, to prevent the half-row counterweight 6 from impacting the float 13 and to achieve adjustable drainage volume, a water-stopping component 15 for sealing the drain outlet of the drain valve and a float 13 located above the water-stopping component 15 for delaying the descent of the inner sleeve 4 are installed on the lower side of the inner sleeve 4. A counterweight support 14 is also fixedly installed on the inner sleeve 4. The counterweight support 14 is located between the half-row counterweight 6 and the float 13 to catch the half-row counterweight 6 when it falls. Both the float 13 and the counterweight support 14 can be adjusted up and down on the inner sleeve 4 to adjust the drainage volume of the water tank.

[0034] This invention features a simple structure and convenient use. A rotating pendulum ring 5 is used to fix the half-row counterweight barrel 6. Because the rotating pendulum ring 5 is tilted upwards on the side near the half-row button 2, when the full-row button 1 is pressed, it cannot touch the rotating pendulum ring 5, and the rotating pendulum ring 5 remains stationary. When the half-row button 2 is pressed, it touches the rotating pendulum ring 5, driving it to rotate and causing the hook 501 to disengage, allowing the half-row counterweight barrel 6 to fall down. This increases the counterweight of the float 13, thereby shortening the drainage time and achieving partial drainage. Furthermore, because this invention uses a rotating pendulum ring 5, there is no need to differentiate the full-row button 1 and the half-row button 2 structurally. A single mold can be used to produce full-row buttons 1 and half-row buttons 2 with identical structures. Additionally, the full-row swing arm 10 and the half-row swing arm 11 can also be manufactured using only one mold, significantly reducing mold-making costs.

[0035] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection of the invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
