Abstract
Description
Technical Field
[0001] This invention belongs to the field of faucets, and in particular to the water control seat of a faucet. Background Technology
[0002] Most existing faucet switches are lever-operated. Flipping the lever opens the water flow, and flipping it back closes it to turn off the water. The problem is that when the lever is turned on, the water flow is often very strong. Adjusting the flow requires repeatedly turning the lever on and off to test the flow, which is inconvenient. Often, when a small flow should be used, a large or medium flow is used, resulting in a waste of water resources.
[0003] For a long time, many water-saving solutions and products have emerged. For example, patent applications for "a type of valve" (201922130715.x) and "an adjustable water flow faucet" (201921168042.0) all employ resistance-based switches composed of grooves or recesses, balls or balls, and springs. Each position has resistance; the resistance increases as the lever is turned, and returns to normal hand-operated resistance after passing a certain position. This "ball-head resistance" structure is suitable for certain single products, such as umbrellas. However, its application in lever-type faucet switches presents several problems: 1. Lever-type faucet switches have a very small angle from a standstill to the maximum water flow position. Within this small angle range, several closely spaced resistance points are set. The backlash zone, or smooth flow zone, between each resistance point is very small. 1. During operation, when the handle is turned, it's easy to exceed the limit between adjacent resistance points, especially when people are busy and tend to turn the handle quickly, making it easy to exceed the limit. 2. This type of resistance switch cannot strictly define the resistance level. After the user turns the handle to the desired position, the handle does not stop automatically; the user must rely on their sense of touch to stop the rotation. When turning the handle through several resistance points, the user must rely entirely on their feel to determine the appropriate resistance level. People are accustomed to the habit of releasing water as soon as they turn the handle, and if they are not careful or their attention is not on the sensor switch, it is easy to exceed the limit. Users find this type of product inconvenient and stop using it. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing water-saving switches and provide a water control base for faucets, hereinafter referred to as the water control base.
[0005] This invention is implemented as follows: A faucet with a throttle control base includes a base body, a handle box, a lifting plate, a lifting plate lifting device, an unlocking plate, an unlocking plate lifting device, a button part, and a stop block assembly. The button part includes a button and a button bar. The button has a lockable button and an unlocking button. The outer end of the button bar is connected to the button. The inner end of the button bar connected to the lockable button is connected to a latching block locking structure. The stop block assembly includes a pry block and a lever pry block. The pry block is integrally formed by a stop block and a lever block A; the lever pry block is integrally formed by a lever handle and a lever block B. The outer end of the lever handle extends outside the bottom plate of the base body and is hinged to the lower end of the lifting plate. The lifting plate, the lifting plate lifting device, the unlocking plate, the unlocking plate lifting device, and the button bar are installed in the handle box, and the stop block assembly is installed in the base body. The lifting plate lifting device includes a push-lifting clip, a button bar, and a throttle block. The throttle block is connected to the side of the lifting plate opposite to the push-lifting clip. The push-lifting clip is integrally formed by a push block and a lifting block intersecting and connecting. The lower end of the push block is inserted into the corresponding slot on the button bar. When the lockable button is pressed, the button bar pushes the push block to rotate and causes the lifting block to rotate synchronously. The lifting block then raises the lifting stop block and the lifting plate by a set distance. The release lifting block above the inner end of the button bar connected to the unlock button only raises the unlocking plate. A connecting block is connected below the lifting block corresponding to the button bar above the lockable button. A release locking clip is installed on the connecting block. A release stop block is connected to the side of the unlocking plate opposite to the release locking clip, and a locking block is connected to the same side of the unlocking plate opposite to the inner end of the button bar. The lifting plate, the upper and lower parts of the unlocking plate are all mounted on a plate base, and there is a set interval between the lifting plate and the unlocking plate. When the lockable button is pressed, the lifting block raises the lifting plate by a set distance, and the release locking clip raises the unlocking plate by a set distance simultaneously. When the lower end of the locking block connected to the unlocking plate is higher than the upper end of the latch block, the latch block below the rear end of the button bar moves with the button bar and immediately enters the locking space. When the locking block falls, it locks the latch block, and the button bar is locked and cannot return to its original position. When one of the lockable buttons is pressed, the strip connected to the previously pressed lockable button is unlocked, and the strip of the newly pressed lockable button is locked. When the unlock button is pressed, the locked strip is unlocked. To operate, place your thumb on the selected speed button, and the other fingers on the opposite side of the handle box. Pinch the buttons together to press them into place, then simultaneously pull the handle box outwards. Release the handle to release the selected water flow. The buttons are located on the side of the handle box. To turn off the faucet, push the handle box inwards to turn off the water. The handle box is connected to the base. The lifting plate consists of an upper and lower section, which are hinged together. When all buttons are not pressed, the user can directly operate the handle box as a regular faucet.
[0006] The advantages of this invention are: 1. Strict control over each speed setting. Pressing the selected speed setting button precisely limits the water flow at that setting, preventing any deviation from the specified limits. 2. A locking device is included. When a speed setting button is pressed, the previously locked button bar is automatically unlocked and returned to its original position, while the last pressed button bar is automatically locked. This allows users to easily see which button setting is currently dispensing water. If the flow is unsuitable, the setting can be adjusted immediately. If the flow is suitable, the setting can be retained so that the appropriate flow can be dispensed directly by opening the handle box next time, providing convenience. 3. The button is located on the side of the faucet handle box. To dispense water, simply place one thumb on the button and the other fingers on the other side of the handle box, pinching inwards to press the selected speed setting button. Then, pull the handle box outwards to dispense the selected water flow. Releasing the hand completes the process. This is the same as the existing process of turning on a faucet, involving three consecutive actions: squeezing the handle (pressing the button), pulling it outwards, and releasing. To turn off the faucet, simply push the handle box inwards to shut off the water. 4. Easy to use; intuitive and intuitive. 5. This invention can be used for both hot and cold water switching, as well as for one-way liquid switching and throttling where pulling the handle outwards releases water. Attached Figure Description

[0021] Figure 1 The image shows the installation diagram of the water control seat on an existing faucet. The water control seat is also called a handle seat. Figure 1 In the middle, on the right is the water control base, which includes a base body 2, a handle box 6, a lifting plate 8, a lifting plate lifting device, an unlocking plate, an unlocking plate lifting device, a button section, and a stop block assembly. In the cross-sectional view of the water control base, a stop block 4 and a lever 9 are installed internally, and the lifting plate 8 is movably connected to the right end of the lever 9. A button 7 is installed on the upper side of the handle box 6. Figure 1 On the left is the existing hot and cold water faucet, including the water outlet pipe 1, valve body 5, and valve handle 3. The right side of the valve handle 3 extends into the handle sleeve inside the water control seat, connecting the water control seat together, so that the water control seat is installed on the existing faucet.
[0022] Figure 2The diagram shows the existing faucet structure. The right side of Figure A shows the existing faucet handle base structure, and the left side shows the structure of the valve body 5 and the valve handle 3 connected to it on the right. Existing hot and cold water faucets come in various appearances; for ease of description, the handle base structure shown in the diagram is used as an example. Figure 2 In the diagram, a water outlet pipe 1 is located above the pipe body 11. The pipe body 11 is connected to the valve body 5. A ring 13 is installed on the right side of the valve body 5, and a valve handle 3 is installed in the ring 13. A valve handle seat 12 is installed on the outside of the valve handle 3. There is a handle pin 10 on the left side of the valve handle. For ease of observation, the handle pin installed inside is shown on the outside. The valve handle 3 can rotate up and down around the handle pin 10. On the right side of Figure A is the existing handle seat, which consists of a seat shell 15, a handle 14, a tapered screw 16, and a handle sleeve 17. The valve handle 3 is a square body. The handle sleeve 17 has a square hole in the middle that matches the valve handle 3.
[0023] In Figure B, the handle seat from Figure A is moved to the left, allowing the handle sleeve 17 to be fitted onto the valve handle 3. The tapered screw 16 mounted on the upper part of the handle sleeve 17 is then screwed into the corresponding tapered recess on the upper part of the valve handle 3, connecting the handle seat to the faucet. Turning the handle 14 to the right in the figure turns the faucet on, and turning it to the left turns the water flow down until it is completely shut off. The faucet in Figure B is in the closed position.
[0024] Figure 3 The diagram shows the different angles at which the handle of an existing faucet is opened. When opening the handle to release water, the water flow is controlled by pulling the handle outwards (to the right of the diagram) to rotate the handle downwards at different angles.
[0025] In Figure A, the handle base is in the closed state, not opened outwards. The ring 13 is a circular shell that slightly contracts inwards and opens to the right. The ring plane 18 refers to the plane containing the right end of the circular ring 13 in the figure. All subsequent observations and explanations regarding the outward opening angle of the handle base will be based on the ring plane 18. In Figure A, the handle base is not opened outwards, and the angle between the plane of the left end of the upper shell and the ring plane is zero degrees. For ease of description and observation, the portion of the handle base shell extending beyond the ring plane on the left side has been cut off in the figure. The lower part of the handle base shell is made into a shape that contracts to the right. The shell is a hollow cylinder.
[0026] In Figure B, the handle seat has been pulled, causing the housing 15 to rotate downwards slightly by an angle. A small angle has appeared between the plane of the housing opening on the upper left end of the handle seat and the plane of the left ring opening. At this time, the water flow from the faucet is small, set to the low water flow setting.
[0027] In Figure C, the handle seat is rotated downwards until there is a larger angle between the upper left end face of the seat and the plane of the bezel than in Figure B. At this point, the faucet is set to a medium water flow.
[0028] In diagram D, the handle seat is rotated downwards until the upper left end face of the seat and the plane of the bezel form a larger angle than in diagram C. At this point, the faucet dispenses water at the high flow rate.
[0029] Using the method described above, multiple settings can be set to control the water flow. The following explanation only covers the four settings: maximum, large, medium, and small.
[0030] Turning the handle of an existing faucet outward causes the handle seat to rotate outward by a pre-set angle, where it stops. The starting point (zero degrees) and the ending point (where the handle seat stops at the pre-set angle) are called the starting point and ending point, respectively. This invention incorporates three stopping points within the rotation angle from the starting point to the ending point in the existing faucet: three buttons, three push-buttons, and corresponding lifting plates, lifting plate devices, unlocking plates, and unlocking plate lifting devices. The three buttons are for low, medium, and high speeds. There is a small angle between the high speed button and the ending point of the handle seat rotation; this ending point is called the maximum speed. Because the maximum speed of an existing faucet is already limited by a fixed obstruction, there is no need for a dedicated button. Simply turning the handle downward and outward causes the handle seat to rotate to the ending point, where it is naturally stopped, releasing the maximum water flow—the same as the existing faucet operation. The following mainly describes the structure, working principle, and operation method of the buttons for the three gear positions.
[0031] Figure 4 The diagram shows the installation structure of the water control seat of this invention replacing the existing faucet handle seat. The left side of Figure A shows the existing faucet structure. A valve handle 3 is installed in the center of the valve handle seat 12 within the right-hand ring 13 on the left side of Figure A. The right side of Figure A shows the water control seat described in this invention. The handle sleeve 17 inside the water control seat is directly opposite the valve handle 3 on the left. First, the tapered screw 16 on the handle sleeve is reversed and moved upwards to exit the space inside the handle sleeve 17.
[0032] Figure B shows the left and right faucets and control seats brought together as shown in Figure A. The handle sleeve 17 in the control seat is already fitted onto the left valve handle 3. There is a suitable fitting clearance between the square inner hole of the handle sleeve 17 and the square handle surface of the valve handle 3. Tighten the tapered screw 16 to the lower position. The control seat is then installed and fixed on the matched faucet. A retaining assembly is installed inside the lower part of the control seat housing 15. The retaining assembly includes a retaining pry block and a lever pry block. The retaining pry block is integrally formed by retaining block 4 and pry block A 24. The lever pry block is integrally formed by lever handle 9 and pry block B 23. The right end of lever handle 9 is movably connected to the lower end of lifting plate 8. Both the lever pry block and the retaining pry block are installed in two clamping plates located below the side of the handle sleeve inside the control seat. The two mounting clamping plates are located in... Figure 6 The narrative in the text, Figure 4The middle plate is not shown. The base plate 19 of the handle box 6 is integrally connected to the right end of the base shell 15. The shell of the handle box 6 consists of the base plate 19 and the cover shell 20. The handle box 6 contains a lifting plate, a lifting plate lifting device, an unlocking plate, an unlocking plate lifting device, and a button bar for the button part. The various components inside the handle box will be... Figure 7 and Figure 8 The description continues. A handle sleeve 17 is provided within the housing 15, and the structural dimensions of the handle sleeve 17 are the same as those of the handle sleeve on a corresponding existing faucet. The buttons include a lockable button and an unlockable button. The lockable button controls the water flow level, and the unlockable button is used to release the lock on the handle. Figure 4 Three of the four buttons shown are for locking gears, and the other is for unlocking.
[0033] Figure 5 The image in the middle shows how the water flow is changed by moving the handle of this water control base to different positions. (Corresponding...) Figure 3 The process of controlling water flow by turning the existing faucet to three positions is explained in the text, and this water control base is also explained using the three positions to control water flow.
[0034] Figures A and B illustrate the process of controlling the small-amplitude water flow. Figures C and D illustrate the process of controlling the medium-amplitude water flow. Figures E and F illustrate the process of controlling the large-amplitude water flow. In the figures, the stop block, handle, pry bar A, and pry bar B are all installed in the two clamps on the lower side of the handle sleeve; these clamps are not shown for clarity.
[0035] The stop block 4 and the pry bar A 24 are integrated to form a stop pry block, both of which can rotate around the same pivot pin 22. The handle 9 and the pry bar B 23 form a lever pry block, both of which can rotate around the same pivot pin 22. A torsion spring 26 with appropriate torque is installed on the stop pry block, which can make the stop block rotate counterclockwise to return to its original position. The pry bar A always presses against the pry bar B, which can make the handle 9 rotate clockwise, that is, the right end of the handle rotates downward to its original position. For ease of observation, only the torsion spring is shown in Figure A; the torsion springs are not shown in the other figures. When the button bar inside the handle box is pressed inward, it drives the lifting plate lifting device to move the lifting plate 8 upward to different distances. The lifting plate pulls the right end of the handle to rotate upward by the corresponding angle. Then, the handle 9 acts on the pry bar B 23, and the pry bar B 23 acts on the pry bar A 24, which will cause the stop block 4 to rotate to the left in the figure by different angles.
[0036] In Figure A, the faucet is in the off position. When the small stop button on the side of the handle box is pressed to the correct position, the stop block 4 rotates to the position shown in the figure. This position of the stop block at this time will be called the preset position.
[0037] In Figure B, after pressing the low-speed button as shown in Figure A, when the handle box 6 is moved to the right, the stop block 4 is blocked by the lower edge of the left ring 13. At this time, the lifting plate 8 is fixed and pulls the lever 9, and the lever cannot be turned downwards anymore, so the stop block cannot move backwards. The water flow released at this time is the low-speed water flow.
[0038] In Figure C, the faucet is in the closed position. Pressing the medium speed button causes the lifting device in the handle box to rotate the lifting plate 8 and the lever 9 upwards. The upward distance of the lifting plate is reduced by the set distance compared to Figure A, thus reducing the leftward tilt of the stop block 4 in Figure C to the set angle. This is the preset angle of the medium speed water flow.
[0039] In Figure D, following the above method, when the handle box 6 is turned downwards, the stop block 4 rests against the lower edge of the ring 13, the water control seat is stopped from rotating, and the faucet releases water. This water flow is called the medium-speed water flow. It can be clearly seen that the angle between the port plane on the upper left side of the seat shell in Figure D and the ring plane 18 marked on the left is larger than the angle in Figure B.
[0040] Similarly, in diagram E, the faucet is also closed. At this point, the upward distance the lever is pulled is shorter than in diagram C, resulting in a smaller angle at which the stop block deflects to the left. This is the preset position for the high-flow rate. Likewise, in diagram F, when the water control seat is rotated downwards, the stop block rests against the lower edge of the left-hand ring, preventing further rotation of the seat. Thus, the high-flow rate is released. At this point, the angle between the port plane above the seat and the ring plane marked on the left in diagram F is the largest because this is the largest downward rotation angle of the seat.
[0041] Figure 6 Figure A shows the installation of the pry bar and lever pry bar between the two clamping plates in the water control seat, and the rotation angle of the pry bar. Figure B is a cross-sectional view of Figure A. In Figure A, the valve handle 3 passes through the square hole in the handle sleeve 17. The two clamping plates 30 are connected to the lower side of the handle sleeve 17. The two ends of the shaft pins 22 of the pry bar and lever pry bar pass through the two clamping plates and are fixed. There is an appropriate gap between the clamping plates and the pry bar and lever pry bar. To facilitate the installation of the pry bar and lever pry bar, the handle sleeve 17 and the right end of the two clamping plates 30 can be fixed to a disc plate 27, making it a removable structure, as shown in Figure A. The bottom shell surface of the seat housing 15 is made into a circular ring plate 29 that mates with the disc plate, which is equivalent to a flange. The disc plate 27 and the circular ring plate 29 are connected together with three screws 28 as shown in the figure. After the pry bar and lever pry bar are installed from the outside, they can be connected to the circular ring plate 29 on the right side of the seat housing 15. Subsequently, the outer end of the handle 9 is connected to the lower end of the lifting plate 8, and the cover 20 has already been removed during installation. The base plate 19 can be made as one piece with the ring plate, or it can be welded together and then polished smooth.
[0042] Figure C omits the disc and ring plate structures shown in Figure A, visually illustrating the process of the baffle controlling the large, medium, and small water flow. Figure 5 In the diagram, block 4 is positioned below the edge of ring 13, indicating the seat is in the high-power position and the faucet is running. To clearly show the comparison of block 4's position at low, medium, and high water levels, dashed lines are drawn to the left of the solid line indicating the low and medium water levels. It can be visually seen that when the block moves left from the solid line to the dashed line for medium, the water flow becomes medium. Moving the block further left from the dashed line for medium to the dashed line for low, the water flow becomes low. Conversely, moving the block from the dashed line for low to the dashed line for medium, and then back to the solid line, changes the water flow from low to medium, and similarly, it can also become high.
[0043] Figure 7 The diagram shows the assembly structure of the components inside the handle box. The cover 20 is cut off from the front of the handle box. The component structure for controlling the speed settings is illustrated using a three-speed water flow as an example. Controlling the speed settings involves two aspects: controlling the lifting distance of the lifting plate and controlling the locking and unlocking of the buttons connected to each lockable speed setting.
[0044] The right side of the diagram shows a lifting plate 8 and an unlocking plate 46. The lifting plate 8 and the unlocking plate 46 are installed overlappingly using the same plate holder 45. The plate holder 45 is fixed to the bottom plate 19 of the handle box.
[0045] On the left side of the diagram are buttons 1 (36), 2 (37), 3 (40), and 4 (41). Each button is connected to a button strip (35). The button strip (35) is installed in a button strip housing (34). The button strip housing (34) is fixed to the base plate (19). Both the button strip and the button strip housing are rectangular, and the button strip can slide freely.
[0046] The buttons are divided into lockable buttons and unlockable buttons. Buttons 2 (37), 3 (40), and 4 (41) are lockable buttons. Button 1 (36) is the unlockable button. The buttons 1, 2, 3, and 4, installed from bottom to top in the diagram, represent the four water flow levels: maximum, medium, and low, respectively.
[0047] In the diagram, a locking block similar in structure to the upper part of the button strip 35 of button one 36 is installed on the upper right end of the button strip. This locking block consists of a push block 38 and a release block 52 connected as one unit, and is also fixed to the base plate by a pivot pin 22. The push block is also inserted into the slot of the button strip. The right end of the release block 52 is below the release block 47. Pressing the button will only lift the unlocking plate 46, not the lifting plate. Button one has a simple structure and its function is only to lift the unlocking plate, so it is drawn smaller than the buttons above in the attached diagram.
[0048] Each of the buttons connected to buttons two, three, and four has a push-lift clip, which is a push block and a lift block connected as one unit, installed above the button strip. The push-lift clip is fixed to the base plate 19 by a pivot pin 22. The push block 38 and the lift block 39 can rotate freely at the same time. A lifting block 44 is connected to the lift plate 8 at the position of the lift block 39. A connecting block 43 is connected below the lift block 39. A release clip 48 is installed on the connecting block 43 by a pivot pin 22. A release block 47 is connected to the upper end of each release clip 48 by the unlocking plate 46. The lower part of each push block passes through the slot opened on the top of the button strip shell 34 and is inserted into the slot opened on the button strip 35. A push block 49 is set on the upper right side of the button strip 35 at the lower section of the release clip 48. A buckle block 51 is connected to the lower right end of the button strip. A locking block 50 is connected to the unlocking plate 46 at the position of the buckle block 51.
[0049] The lifting plate 8 is divided into an upper section and a lower section, which are hinged together. The lower end of the lower section of the lifting plate is movably connected to the handle 9. The upper and lower sections of the lifting plate are collectively referred to as the lifting plate.
[0050] Figure 8 In the middle, is Figure 7 The lifting plate, unlocking plate, and mounting strip structure are shown in the diagram. Figure 7 , Figure 8 In the middle, button three is pressed, but the back end of the button bar is locked. Figure A shows the situation... Figure 7 The same figures are used for ease of annotation and comparison. Figure B is an enlarged view of Figure A from direction D. Figure C is an enlarged view of Figure A from direction C. Figure D is an enlarged sectional view of Figure A from direction AA. The lifting block 44 and the unloading block 47 are not significantly different in horizontal height. However, the horizontal distance between the lifting block 44 and the unloading block 47 is drawn larger in the figure so that the lifting block 39 and the lifting block 44 are not obscured by the unloading block 48 and the unloading block 47. Figures 7 to 10 That's how they're all drawn.
[0051] The lifting plate 8 and the unlocking plate 46 are mounted overlappingly in two plate holders 45. There is one plate holder 45 at the top and one at the bottom. The plate holders are fixed to the base plate with screws 28, as shown in Figure B. A partition 54 separates the lifting plate 8 and the unlocking plate 46 by a set distance. The lifting plate 8 is in the inner rectangular hole, and the unlocking plate 46 is in the outer rectangular hole. Both the lifting plate and the unlocking plate can slide freely up and down.
[0052] Figure C shows the installation structure of the release clip. Connecting block 43 and lifting block 39 are connected as one unit. The release clip 48 has a pin hole in the middle. The pin passes through the countersunk hole on the release clip and the fixing hole on the connecting block, fixing the pin to the connecting block. The release clip can rotate freely. Alternatively, a structure of two clamping plates can be made below the connecting block. Both clamping plates are thinner than the upper section of the connecting block. Pin holes as shown in the figure are also made on the two clamping plates. The release clip is clamped between the two clamping plates, allowing it to rotate freely. This is a common method in the existing machinery industry, not shown in the figure, but only illustrated using one connection method shown. The release clip head 55 at the upper end of the release clip 48 is shaped as shown in Figure A, used to quickly clamp under the release block 47 for easy lifting of the release block. The release clip is also equipped with a spring, the spring force always causing the release clip head to deflect towards the release plate. Installing springs is a common existing technology with various methods; for clarity, the spring is not shown in the figure. A stop pin 33 is fixed on the bottom left side of the release card. As shown in Figure A, when the upper and lower buttons are not pressed, the release card heads corresponding to the respective button strips 35 are all under the release block 47. At this time, the lower left side of the release card is blocked and limited by the stop pin 33. When the middle button 3 40 in Figure A is pressed, the push block 49 on the right side of the button strip pushes the lower left side of the release card 48, so the upper part of the release card swings to the left, and the release card head 55 retracts from under the release block 47. At this time, the unlocking plate 46 immediately moves down under the action of the return spring 64 and is blocked on the plate base by the limit block 67 connected below.
[0053] Figure D is an enlarged view of Figure A (AA). In Figure A, because the press bar is surrounded by a press bar shell, the distance between the press bar shell, the press bar's groove, and the base plate is larger than the thickness of the push block and lifting block. Therefore, the lower part of the push block 38 is made as shown in Figure D. The lower section 57 of the push block is folded outward so that it is not in the same plane as the push block 38 and the lifting block 39. Grooves 25 are provided on the press bar shell and at corresponding positions on the press bar. The lower section 57 of the push block passes through the groove on the press bar shell and inserts into the groove 25 on the press bar. The pin 22 fixes the push block 38 and the lifting block 39 to the base plate 19.
[0054] A lifting block 44 is connected to the lifting plate 8 at the end of each lifting block 39. A release block 47 is connected to the unlocking plate 46 at the head of each release card 48. A locking block 50 is connected to the unlocking plate 46 at the buckle block 51 below the inner end of each push bar.
[0055] The lower part of the unlocking plate 46 is slightly shorter than the lifting plate 8. A limiting block 67 is connected to one side of the lower section of the unlocking plate near the plate base 45 to limit the height of the unlocking plate's descent. A return spring 64 is installed on the lower section of the unlocking plate.
[0056] The lifting end 56 is used to lift the lifting plate 8, and the unlocking end 55 is used to lift the unlocking plate 46. The upper and lower parts of the unlocking plate and the lifting plate do not interfere with each other.
[0057] A torsion spring 26 is installed on the push-lift plate. The spring force of the torsion spring always acts on the push block in the direction of the button. The torsion spring installed on the push-lift plate is also the spring that returns the button bar to its original position after it is pressed, and it also allows the lift block and connecting block to reverse and return to their original positions simultaneously. The return spring force of the lift plate is... Figure 5 The torsion spring mounted on the stop shown provides elasticity. Figure 5 The spring force installed on the middle stop block always causes the handle to rotate clockwise around the pivot pin, so that the handle is downward and the end of the handle is always pulled downward by the lifting plate.
[0058] Figure 9 The middle section is a comparison chart showing the different heights the lifting plate rises when buttons two, three, and four are pressed. Figure 9 In the diagram, the unlocking plate and release card have been removed, and the lifting height of the lifting plate at each position is displayed separately. In the diagram, all three buttons are shown in an unpressed state. The push blocks at the three positions, under the action of springs, push the three push bars into place towards the button heads, with the push bars blocked by the stop pins 33 connected below them. At this time, all three lifting blocks are angled downwards.
[0059] Button 41 and its connected bar 35 are in the leftward return position. The push block, lift block, and connecting block are all solid line figures. At this time, the end 56 of the lift block is resting against the bottom of the lifting block 44 connected to the lifting plate. At this time, draw a parallel line from below the lifting block to the outside of the right-hand figure; this solid line is called the lifting block starting point line 59. When button 4 is pressed, the bar pushes the push block to rotate to the right, and simultaneously the end of the connected lift block rotates upward, causing the upper lifting block to rise and reach its position. Thus, the lift block is lifted into position. See the solid line position at the start of the upward rotation of the lift block and the dashed line position when the lifting block is lifted into position. At this time, draw a parallel line from below the dashed lifting block to the outside of the right-hand figure; this line is called the lifting block highest point line 58. The distance between the two lines is called the lifting height 60. According to... Figure 5 The water flow varies at each setting. The rotation angle of the stop and lever, and the lifting height of the baffle connected to the outer end of the lever, determine the water flow of the faucet. Ultimately, the goal is to change the lifting height of the baffle to three different heights for the three button settings. However, the travel of the three buttons is the same, and the rotation angle of the three baffles is also the same, which are difficult to change. Therefore, [the following is omitted as the original text is incomplete and cannot be translated]. Figure 7The line extending from the bottom of the dashed line at the highest point of the lifting block corresponding to button four is used as the comparison line. The connection and fixed position of the lifting blocks on the lifting plate are changed by altering the lifting block positions corresponding to buttons two and three. Specifically, first, press buttons two and three to their designated positions. Record the height reached by rotating the corresponding lifting block ends upwards as the highest point line 58 to be reached by the lifting block in each gear, i.e., the comparison line. Next, measure the lifting height dimension of each gear downwards from the comparison line on the lifting plate according to the set lifting height dimension. This serves as the fixed position of the lifting block. Thus, the fixed position of the lifting block 44 corresponding to the lifting block ends of buttons two and three on the lifting plate, i.e., the solid line position, is shown in the figure. By drawing the lifting heights of buttons two and three using the same method as button four, it is clear and intuitive that the lifting height corresponding to button four is the largest.
[0060] The lifting block corresponding to button four begins to move upwards as soon as it starts rotating upwards. However, the lifting block corresponding to button three is still some distance from its corresponding lifting block when it begins to rotate upwards. Similarly, there is also a distance between the lifting block corresponding to button two and its corresponding lifting block.
[0061] The distance corresponding to button four is greater than that corresponding to button two. It can be seen that button four corresponds to the largest lift, button two to the smallest lift, and button three to a medium lift, falling between button four and button two. According to... Figure 5 As illustrated in the diagram and explanation, the greater the lifting height, the smaller the downward angle of the water control seat, resulting in a smaller water flow. Conversely, the smaller the lifting height, the larger the downward angle of the water control seat, resulting in a larger water flow. Therefore, button two is for high water flow, button three for medium water flow, and button four for low water flow. Since the travel of the buttons is the same, the turning angles of the push and lift blocks corresponding to each setting are also the same. Therefore, after pressing their respective buttons, the lift block ends corresponding to buttons three and two must rotate freely for a certain angle before contacting their respective upper lift blocks and moving upwards together.
[0062] Figure 10 The diagram below shows the working principle of the locking device. Only button four is shown in the diagram, and we will use button four as an example for explanation. Diagram A shows the button bar not pressed. Diagram B shows the button already pressed and about to be fully engaged. Diagram C is an enlarged view (M) of diagram B. Diagram D shows the button fully engaged and the button bar locked. Diagrams E and F are enlarged views (N) of diagram D.
[0063] In Figure A, when the button is not pressed, push block 38 pushes the button bar to the left under spring force, causing it to return to its original position. During the return process, push block 38, lifting block, and connecting block rotate clockwise together. Connecting block 43 causes release clip 48 to rotate downwards and to the left by a set angle. At this time, release clip 48 moves downwards the most and to the right the least. However, under the return spring force, the release clip head is always biased to the right. At this time, the release clip head is still resting against the release block 47. The latch block 51 at the right end of the button bar is at a set distance from the locking block 50.
[0064] In Figure B, when the button in Figure A is pressed to the right, the latch 51 at the right end of the button bar moves to the right from its position in Figure A. Simultaneously, the pusher 49 at the rear of the button bar pushes the release card 48 to the left below. The release card rotates counter-clockwise and moves upward with the latch, lifting the release block and causing the unlocking plate to rise. The rising unlocking plate then raises the locking block 50 on the unlocking plate. At this time, the latch is passing under the locking block to the right, with the lower end of the locking block higher than the upper end of the latch by a set distance to allow the latch to pass smoothly under the locking block and be pressed into place smoothly to the right. At this time, the release card head at the upper end of the release card swings to the left, almost completely retracting from under the release block. The button is not yet fully pressed in. As the release card rotates counter-clockwise, the tip of the release card head moves to the left in the figure, retracting from under the release block 47, and is about to disengage from the release block. At this point, the latch block 51 on the right end of the latch has moved below the locking block 50 and is about to enter the right-side locking zone 63, as shown in Figure C. At this time, the bottom of the locking block is already significantly higher than the top of the latch block. This difference in height will increase further during the process of the release clip separating from the release block.
[0065] In Figure D, the button in Figure A is not yet fully pressed. As the button is pressed further, the button bar moves the latch block to the right, fully entering the space below and to the right of the locking block 50. At this moment, the pusher 49 at the rear of the button pushes the lower section of the release lever into place, and the release lever head at the upper end of the release lever 48 completely disengages from the release block 47. The unlocking plate 46 then falls downwards under the force of the return spring. The locking block 50 falls with the unlocking plate 46, landing to the left of the latch block 51, thus blocking it. Just before the user releases the button, the button bar moves slightly to the right, and the latch block also moves slightly to the right, as shown in Figure E. After release, the button bar immediately moves to the left under the force of the return spring, but by then the locking block 50 has already fallen and is blocking the left side of the latch block 51, thus blocking the latch block, as shown in Figure F. Therefore, the latch block and the button bar are locked. At this point, the button is already pressed into place. The release card head at the top of the release card has now retracted from under the release block and is about to swing slightly towards the release block again. As shown by the dotted line at the top of the release card in Figure D, the release card quickly swings slightly to the right. Since the unlocking plate has already fallen into place, the release card head is now above the release block, as shown by the solid line at the release card head in Figure D.
[0066] Figure C is an enlarged view of M in Figure B. At this point, the unlocking plate has been raised by the release mechanism to a height above the upper limit of the latch block, above the set height of the latch block. The right side shows the latch block as a dotted line, and the left side as a solid line. There are two possible processes for this: First, when the button is pressed, the latch block moves to the right into the locking zone 63, passing under the raised lock block, as shown in the figure where the latch block moves from the solid line to the dotted line. Second, when another button is pressed, and the release mechanism of that button raises the unlocking plate to a height above the upper limit of the latch block, the locked latch block in Figure D immediately moves back to its original position to the left along with the button bar. In this case, the latch block also passes under the lock block, as shown in Figure C where the latch block moves from the dotted line to the solid line.
[0067] The situation shown in Figure C illustrates two points: First, regardless of whether the latch block passes under the locking block from left to right or right to left, it must be prevented from landing on the latch block when it falls. Second, if the locking block lands on the latch block, it should not impede the latch block's left or right passage.
[0068] To address the issue of the lower end of the locking block landing on the upper surface of the buckle block during its descent, the horizontal width of the locking zone in the diagram is appropriately widened to be greater than the horizontal width of the buckle block. Based on the structure and working principle of each control component of the water control base, the lifting of the unlocking plate and the pressing of the button to move the push bar and buckle block to the right are synchronized. During product design and manufacturing, the buckle block begins to enter the lower end of the locking block when the lower end of the locking block is just above the upper end of the buckle block, as shown in Figure B. As the locking block continues to rise, the buckle block has passed the lower end of the locking block and entered the locking zone, as shown in Figure E. At this point, the buckle block continues to move a set distance to the right within the locking zone as the button is pressed further, stopping when the button is fully pressed. At this point, the locking block falls to the left of the buckle block, still a set distance away. When the user releases the button, the push bar and buckle block immediately move back to their original positions to the left, thus the buckle block is blocked by the locking block, and the push bar is locked, as shown in Figure F. There is no situation where the locking block falls on the upper surface of the buckle block during button pressing. Second, the return spring force on the push block should be stronger than that of the unlocking plate. When the latch returns from the locking zone, the lower end of the locking block is just above the upper end of the latch, and the latch quickly passes under the locking block to the left, much faster than manually pressing the button. At this point, the latch has already passed under the locking block, while the locking block continues to rise. Many existing mechanical structures and devices exist that allow the locked object to pop out instantly upon releasing the locking mechanism, much faster than manual operation. There is no issue of the locking block falling onto the latch when the button is pressed to return.
[0069] Even if a locking block accidentally lands on the upper surface of the latch block during its descent, it will not prevent the latch block from moving left or right beneath the latch block. This is because: 1) the pressure applied by the hand while pressing the button is much stronger than the spring force of the unlocking plate; during pressing, the upper surface of the latch block slides past the lower surface of the latch block, completing the latch block's entry into the locking zone. 2) when the latch block returns to its left position, the upper surface of the latch block similarly slides past the lower surface of the latch block, returning to its normal position.
[0070] Figure 11 The diagram below illustrates the working principle of unlocking the previously pressed button by pressing a new button. In the diagram, the dotted line at the center of button 3 (40) represents the previously pressed button. The dotted line at the rear of button 3's button bar indicates the position of the latch block locked by the locking block. The push block behind the button bar is also located at the dotted line position, consistent with the previous attached diagrams and explanations.
[0071] When button 41 is pressed, the distance from the dotted line to the solid line indicates that button 4 is not yet fully depressed. This is similar to... Figure 10As shown in Figure B, the locking block is raised to its lower end, a certain distance above the latch block, and the latch block moves to the right, passing through the shape below the locking block. Because the unlocking plate corresponding to button four raises the locking block synchronously to its lower end, above the latch block, the latch block at the rear of the previously locked button three quickly moves to the left, passing under the locking block. The button bar, along with button three, immediately returns to its solid line position to the left. The button bar of button three is thus unlocked.
[0072] When button four is pressed down to its final position, the latch at the rear of the button bar enters the locking zone, the locking block drops, and locks the latch, thus locking the button bar of button four. This is consistent with... Figure 10 The same applies to the diagram. Pressing any button unlocks the bar associated with the last pressed button and locks the bar associated with itself.
[0073] Figure 12 The middle section is a diagram illustrating the working principle of the unlock button. Figure 12 The diagram below shows the working principle of button one. Button one (36) can only raise the unlocking plate (46), not the lifting plate (8). The water control base contains corresponding stops (4) for buttons two, three, and four, as shown in the diagram. Figure 5 , Figure 6 The image shows an obstruction in the existing water control seat (handle seat) that limits the rotation of the water control seat to three angles. When the existing water control seat is opened outwards to release water, a fixed obstruction prevents further rotation when it reaches its maximum angle. Therefore, the water control seat of this invention eliminates the obstruction for the maximum position (first position) button. Thus, pressing button four does not require lifting the lifting plate. Button one is specifically designed to unlock any of the locked buttons two, three, or four, effectively removing obstructions from the water control seat's rotation angle from minimum to maximum, clearing obstacles until the maximum rotation angle is reached.
[0074] In Figure A, button 3 (40) has been pressed, and its button bar is locked. Buttons 1, 2, and 4 are all in the return position. The right end of the release block 52 corresponding to button 1 is below the release block 47.
[0075] In Figure B, pressing button one causes the pusher block 38 to rotate to the right, which in turn rotates the lifting block 52 upwards, raising the unlocking plate to a set height. This immediately unlocks button three and causes it to return to its left position. At this point, buttons two, three, and four are in their returned positions, while button one is still pressed. Releasing the button immediately causes it to return to its left position. At this point, the lifting plate and unlocking plate are in their returned positions. The user can stop by pulling the handle outwards until it reaches the maximum water flow.
[0076] Figure 13 The middle section is a diagram illustrating how to operate the water control seat. Figure 13Figures A and B illustrate how to press the button. Figure A shows the side of the handle housing 6 containing the button, facing away from the paper, meaning the front of the handle housing is not visible. Figure B shows both the side of the handle housing containing the button and the front of the handle housing. The button pressing method is as follows: To press the large-position button (button 2, 37) on the handle housing, place your thumb 66 on the large-position button while simultaneously placing the other fingers on the other side of the handle housing. Then, pinch both fingers together to press the large-position button into place. This method avoids the problem of the handle housing 6 tilting to the other side when pressed from one side. In both Figures A and B, the water control base remains closed.
[0077] In Figure C, as shown in Figures A and B, pinch handle box 6 and gently pull it outwards (to the right in the figure). The handle box will then rotate outwards to its designated position and stop rotating. At this point, the faucet will release a high flow of water. Release your grip. After releasing your grip, the handle box will continue to release water while still tilted to the right as shown in the figure. To switch from a high flow to a low flow, turn the handle back to the position shown in Figure A, press the low flow button (button 41), and then gently pull the handle box to the right again until it stops rotating. Release your grip; this time, a low flow of water will be released.
[0078] For existing hot and cold water faucets, people are accustomed to turning the handle to the left for hot water and to the right for cold water. Depending on the selected hot or cold water temperature, users can turn the handle to the left or right in Figures A and B, or in Figure C, to either position. To turn off the faucet after dispensing water, simply push the handle inwards. This is the same as the traditional method of use. After a few uses, users will quickly press the button on one side of the handle and the other side simultaneously, allowing for easy operation. The button can be located on either side of the handle.
[0079] The instruction manual uses a faucet with four buttons as an example to explain its structure and working principle. The number of buttons should be determined based on the faucet's operating environment, the valve core and pipe opening size, and the water pressure. Generally, three buttons are sufficient for most household faucets: high (maximum), medium, and low.
