Convenient water control base for faucet

Abstract

The convenient water control seat of the faucet includes a seat body, a handle box, a lifting frame, an inclined plane lifting device, a button, and a blocking card group. An operating bar, an inclined plane lifting device, and an inclined block are installed inside the handle box. The outer end of the operating bar is connected to the button, and the inner end is integrally connected to the inclined block. The button is installed on the side of the handle box. The blocking card group is installed inside the seat body. There is a blocking block in the blocking card group that can limit the rotation angle of the water control seat to thus limit the water flow rate of each gear. The pry block connected to the blocking block is in contact with the pry block connected to the lever handle. When a button is pressed, the operating bar pushes the inclined block to pass through below the inclined panel in the inclined plane lifting device to thus lift the inclined panel, causing the lower end of the inclined plane lifting device to pull the outer end of the lever handle, and the lever handle then causes the blocking block to rotate by a set angle through the pry block. When the handle box is pulled outwards, the water control seat is blocked and stops, and the water flow of the selected gear is discharged. When the faucet is opened, it is fast and convenient, and the gears are clearly separated from each other and cannot cross the boundary. It has good use and water-saving effects, and can reduce the splashing phenomenon.

Description

Technical Field

[0001] The present invention belongs to the field of faucets, and particularly to a convenient water control seat for faucets. Background Art

[0002] Most of the existing faucet switches are handle-type toggle switches. When the switch is toggled open, water flows out, and when toggled back in the reverse direction, the water shuts off. The problem is that when the switch is toggled open, the water flow is often very large. When trying to turn the water flow down, one often has to repeatedly toggle the switch to a large flow and then back to a small flow to test the water flow, which is inconvenient to operate. Often, when small water flow is needed, large or medium water flow is released instead, resulting in a waste of water resources.

[0003] For a long time, there have been many water-saving solutions and quite a few water-saving products have emerged. For example, the patent application number of "A stepped valve" is 201922130715.x, and the patent application number of "A faucet with adjustable water output" is 201921168042.0. These types of patented technical solutions are all resistance stepped switches composed of grooves or pits, marbles or ball heads, and springs. That is, some resistance is set at each step. When the wrench passes a certain step, the resistance is greater, and after passing the resistance, the wrench returns to the normal hand-operated resistance. This "ball head resistance" structure is very suitable for some single products, such as umbrellas. However, when used in a wrench or faucet switch, there are these problems: 1. For a handle-type faucet switch, the angle from the static state to the maximum water flow position is very small when toggled open. Several resistance points are set in this small angle range and are very close to each other. The recoil area, that is, the stable area, between each resistance point is very small. When operating, when the hand toggles the handle, it is very easy to cross the boundary between adjacent resistance points. Especially when people are busy, they often toggle the handle relatively quickly, and it is most likely to cross the boundary between gears. 2. This type of resistance switch cannot strictly define the steps. After the user toggles the handle to the position, the handle cannot automatically stop and depends on the user's perception to stop the rotation of the handle. When toggling the handle through several resistance points, it entirely depends on the user's hand feeling to determine the large and small steps. Since people are used to the operation habit of toggling open to release water, as long as they are not careful or their attention is not on perceiving the switch, it is most likely to cross the boundary and pass the step. After using these types of products, people find them inconvenient and no longer use them. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing water-saving switches and provide a convenient water control seat for faucets, hereinafter referred to as the water control seat.

[0005] The present invention is implemented as follows: the convenient water control seat of the faucet includes a seat body, a handle box, a lifting frame, an inclined lifting device, a button, and a blocking card group. The button is composed of a key head and an outer end of a push bar connected together. The inclined lifting device is composed of an inclined panel, a flat panel, and an inclined block. The inclined block is arranged at the inner end of the push bar. The inclined panel and the flat panel are fixed on the lifting frame. The inclined panel and the flat panel are connected as a whole. The push bar is installed vertically with the lifting frame. A return spring is installed on the push bar. The push bar, the return spring, and the lifting frame are all installed in the handle box. The inclined panel and the flat panel are arranged at the inclined block position at the rear end of the push bar corresponding to each pair of buttons on the lifting frame. The blocking card group includes a blocking pry block and a lever pry block. The blocking pry block is composed of a blocking block and a pry block A made into one body. The lever pry block is composed of a lever and a pry block B made into one body. When the button is pressed, the push bar pushes the inclined block to move a set distance from the bottom of the inclined panel, even if the lifting frame is raised by a set distance. When the upper plane of the push bar connected to the upper surface of the inclined block enters the lower surface of the flat plate connected to the lower end of the corresponding inclined plate on the lifting rack, the lifting rack is temporarily locked and cannot move down. The lower end of the lifting rack is movably connected to the rear end of the trigger. When the button is released, the push bar moves in the direction of the button together with the inclined block under the action of the return spring, and the lifting rack is no longer locked and can move down. When the button of a gear is pressed to the right position, the lifting rack pulls the trigger to rotate upward by an angle, so that the block rotates a corresponding angle to limit the size of the water flow. The operation method is to use the thumb to face the selected gear button position, and the other fingers are on the other side of the handle box. The fingers on both sides are pinched relative to each other, that is, the button is pressed to the right position, and the handle box is pulled outward without letting go. When it is in place, it stops, and the selected gear water flow is released. The button is installed on the side of the handle box. When you want to turn off the faucet, push the handle box inward to the right position to turn off the water. The handle box is connected to the seat body. When no button is pressed, the user can directly pull the handle box to use it as an existing faucet. The outer end of the handle extends out of the bottom plate of the seat body and is hinged to the lower end of the lifting frame.

[0006] The advantages of the present invention are: 1. Each gear position is strictly controlled. As long as the selected gear position button is pressed, the water flow size of the gear position is clearly limited, and the gear positions cannot cross the boundary. 2. The button is set on the side of the faucet handle box. When you want to release water, just press one thumb on the button, and the other fingers are on the other side of the handle box. The fingers on both sides pinch inward to press the selected gear position button, and then pull the handle box outward to release the selected gear water flow. Let go and it's done. This is the same as the existing process of opening the faucet, which is also three consecutive actions. Pinch the handle, that is, press the button, pull it outward, and let go, which are also three actions. When turning off the faucet, push the handle box inward to turn off the water. 3. It is easy to use and you will know it at a glance. 4. The present invention is used for both cold and hot water two-way switches, and can also be used for unidirectional liquid switch throttling that releases water when the handle is pulled outward.

Embodiment

[0019] Figure 1 In this figure, it is the installation diagram of the water control seat on the existing faucet. The water control seat is also called the handle seat. Figure 1 In this figure, on the right is the water control seat, which includes a seat body 2, a handle box 6, a lifting frame 8, an inclined plane lifting device, a button 7, and a retaining card group. In the cross-sectional view of the water control seat, a retaining block 4 and a lever handle 9 are installed inside, and the lifting frame 8 is movably connected to the right end of the lever handle 9. The button 7 is installed on the upper side of the handle box 6. Figure 1 On the left in this figure is the existing cold and hot water faucet, which includes a water outlet pipe 1, a valve body 5, and a 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, that is, installing the water control seat on the existing faucet.

[0020] Figure 2 In this figure, it is the structure of the existing faucet. On the right in Figure A is the structure of the handle seat of the existing faucet, and on the left is the position structure of the valve handle 3 connecting the valve body 5 on the right side. There are various appearance styles of the existing cold and hot water faucets. For the convenience of description here, the appearance structure of the handle seat shown in the figure is selected as an example. Figure 2 In this figure, there is a water outlet pipe 1 above the pipe body 11. The pipe body 11 is connected to the valve body 5. A ring mouth 13 is installed on the right side of the valve body 5, and a valve handle 3 is installed in the ring mouth 13. A valve handle seat 12 is installed outside the valve handle 3. There is a handle shaft pin 10 on the left side of the valve handle. For the convenience of observation, the handle shaft pin installed inside is drawn outside here. The valve handle 3 can rotate up and down around the handle shaft pin 10. On the right in Figure A is the existing handle seat, which is composed of a seat shell 15, a handle 14, a taper screw 16, and a handle sleeve 17. The valve handle 3 is a square body. The middle of the handle sleeve 17 is a square hole matching the valve handle 3.

[0021] In Figure B, the handle seat in Figure A is moved to the left, the handle sleeve 17 is sleeved on the valve handle 3, and the taper screw 16 installed above the handle sleeve 17 is screwed into the corresponding conical pit above the valve handle 3, so that the handle seat is connected to the faucet. Pulling the handle 14 to the right in the figure opens the faucet to release water, and turning the handle to the left in the figure reduces the water flow until it is completely closed. The faucet in Figure B is in the closed state.

[0022] Figure 3 In this figure, it is the diagram of the existing faucet handle seat being opened at different angles. When opening the existing faucet handle seat to release water, it is to pull the handle outward, that is, to the right in the figure, so that the handle seat rotates downward at different angles to control the water flow size.

[0023] In Figure A, the handle base is in the state where it is not pulled outwards, i.e., the closed state. The ring opening 13 is a circular housing that is slightly constricted inwards and open to the right. The ring opening plane 18 refers to the plane where the right end of the circular ring opening 13 is located in the figure. Hereinafter, all the angles at which the handle base is pulled outwards are observed and described with reference to the ring opening plane 18. In Figure A, the handle base is not pulled outwards, and the included angle between the left port plane of the upper housing of the handle base and the ring opening plane is zero degrees. For the convenience of narration and observation, the part of the left side of the housing of the handle base that extends beyond the ring opening plane in the figure has been cut off. The lower part of the housing of the handle base is made to contract towards the right. The housing is in the shape of a hollow cylinder.

[0024] In Figure B, the handle base has been pulled to rotate the housing 15 downwards by a small angle. A smaller included angle has appeared between the upper shell opening plane of the housing 15 at the left end of the handle base and the left ring opening plane. At this time, the water flow discharged from the faucet is small, and it is set as a small water flow gear.

[0025] In Figure C, the handle base is pulled and rotated downwards until there is a larger included angle between the upper left end face of the housing and the ring opening plane than in Figure B. At this time, the water flow discharged from the faucet is set as a medium water flow gear.

[0026] In Figure D, the handle base is pulled and rotated downwards until there is a larger included angle between the upper left end face of the housing and the ring opening plane than in Figure C. At this time, the water flow discharged from the faucet is set as a large water flow gear.

[0027] According to the above method, multiple gears for controlling the water flow size can be set. Hereinafter, only the four gears of maximum, large, medium, and small are described.

[0028] Pull the handle of the existing faucet outwards and rotate it, which will drive the handle base to also rotate outwards by a fixed set angle when it was originally factory-produced and then be blocked and stop. Here, the position where the handle base starts to rotate outwards, i.e., zero degree, is called the starting point, and the position where the handle base rotates to the position where it is blocked by the originally fixed setting and stops is called the end point. In the rotation of the existing faucet in the present invention, three blocking points are set within the rotation angle from the starting point to the end point, i.e., three buttons, three pressing bars, and the corresponding lifting frames, inclined planes, and inclined blocks are set. The three buttons are the small gear button, the medium gear button, and the large gear button respectively. There is still a smaller angle between the large gear button and the stopping position at the end of the rotation of the handle base. The end position of the rotation of the handle base is called the maximum gear. Because there is already a fixed blocking object for the maximum gear of the existing faucet itself, there is no need to set a button for the maximum gear. As long as none of the three buttons are pressed in, directly pull the handle to rotate the handle base outwards and downwards to the end point and the natural blocked position, i.e., discharge the maximum water flow, which is the same as the operation method of the existing faucet. The following mainly describes the relevant structures, working principles, and operation methods of the three buttons.

[0029] Figure 4In the figure, it is the installation structure diagram in which the water control seat of the present invention replaces the existing faucet handle seat. On the left side of Figure A is the existing faucet structure. Inside the valve handle seat 12 within the right circular opening 13 on the left side of Figure A, a valve handle 3 is installed in the middle. On the right side of Figure A is the water control seat of the present invention. The handle sleeve 17 inside the water control seat faces the valve handle 3 on the left. First, the tapered screw 16 on the handle sleeve is unscrewed counterclockwise and withdrawn from the space inside the handle sleeve 17.

[0030] In Figure B, the faucet and the water control seat on the left and right sides in Figure A are brought closer together, and the handle sleeve 17 in the water control seat has been sleeved on the valve handle 3 on the left. There is an appropriate fitting clearance between the square inner hole of the handle sleeve 17 and the square body handle surface of the valve handle 3. The tapered screw 16 is turned to the proper position. The water control seat has then been installed and fixed on the paired faucet. Below the inner side of the seat shell 15 of the water control seat, a blocking group is installed. The blocking group includes a blocking lever block and a levering block. The blocking lever block is integrally formed by a blocking block 4 and a levering block A 24. The levering block is integrally formed by a lever handle 9 and a levering block B 23. The right end of the lever handle 9 is movably connected to the lower end of the lifting frame 8. Both the levering block and the blocking lever block are installed in two clamping plates at the lower side position on the side of the handle sleeve inside the seat body. The two installation clamping plates are Figure 6 described in Figure 4 and are not drawn in Figure 7 and Figure 8 The seat shell 15 is provided with a handle sleeve 17, and the structural dimensions of the handle sleeve 17 are the same as those of the handle sleeve of the handle seat on the corresponding existing faucet.

[0031] Figure 5 In the figure, it is the diagram of the situation where the handle box of this water control seat is turned to several gears to change the water flow rate. In Figures A and B, it is the process of controlling the small water flow rate. In Figures C and D, it is the process of controlling the medium water flow rate. In Figures E and F, it is the process of controlling the large water flow rate. In the figure, the blocking block, the lever handle, the levering block A, and the levering block B are all installed in two clamping plates on the lower side of the side of the handle sleeve. For the sake of clarity of the drawing, the clamping plates are not drawn.

[0032] The blocking block 4 and the levering block A 24 are integrally formed to form the blocking lever block. Both the blocking block and the levering block A can rotate around the same pivot pin 22. The lever handle 9 and the levering block B 23 form the levering block. Both the lever handle and the levering block B can rotate around the same pivot pin 22. An appropriately torqued torsion spring 57 is installed on the blocking lever block, which can make the blocking block rotate counterclockwise to return to its position, and the levering block A always presses against the levering block B, which can make the lever handle 9 rotate clockwise, that is, the right end of the lever handle rotates downward to the proper position. When the inclined block at the right end of the pressing bar of the button inside the handle box makes the lifting frame 8 move upward to different distances, the lifting frame pulls the right end of the lever handle to rotate upward by a corresponding angle. Then, the lever handle 9 acts on the levering block B 23, and the levering block B 23 acts on the levering block A 24, which will cause the blocking block 4 to rotate to the left in the figure by different angles.

[0033] In Figure A, the faucet is in the closed state. When the small gear button on the side of the handle box is pressed in place, the stop block 4 rotates to the position shown in the figure. Hereinafter, the position of the stop block at this time is called the preset position.

[0034] In Figure B, after the small gear button is pressed in Figure A, when the handle box 6 is pulled to the right, the stop block 4 leans against the lower edge of the left ring opening 13 and is blocked. At this time, the lifting frame 8 fixedly pulls the lever handle 9, and the lever handle cannot rotate downward anymore, and the stop block cannot retreat. The water flow discharged at this time is the small gear water flow.

[0035] In Figure C, the faucet is in the closed state. When the medium gear button is pressed, at this time, the inclined block in the handle box causes the lifting frame 8 to pull the lever handle 9 to rotate upward. At this time, the distance that the lifting frame pulls upward is reduced by a set distance compared to Figure A, so that the leftward swing of the stop block 4 in Figure C is reduced to a set angle. This is the preset angle of the medium gear water flow.

[0036] In Figure D, according to the above method, when the handle box 6 is rotated downward, the stop block 4 leans against the lower edge of the ring opening 13, and the water control seat is blocked and stops rotating, and the faucet discharges water. The water flow at this time is called the medium gear water flow. It can be clearly seen at this time that the included angle between the port plane on the left above the seat shell in Figure D and the marked ring opening plane 18 on the left is larger than that in Figure B.

[0037] Similarly, in Figure E, the faucet is also in the closed state. At this time, the distance that the lifting frame pulls upward is shorter than that in Figure C, so the angle of the leftward swing of the stop block is smaller. This is the preset position of the large gear water flow. Similarly, in Figure F, when the water control seat is rotated downward, the stop block leans against the lower edge of the left ring opening, and the seat body cannot continue to rotate and stops. So the discharged water is the large gear water flow. At this time, the included angle between the port plane above the seat shell in Figure F and the marked ring opening plane on the left is the largest among the above three gears, because the angle of the downward rotation of the seat body is the largest at this time.

[0038] Figure 6In the figure, it shows the situation where the blocking lever block and the prying lever block are installed between two clamping plates in the water control seat and the rotation angle situation of the blocking block. Figure B is the A-A cross-sectional view of Figure A. In Figure A, the valve handle 3 passes through the square hole of the handle sleeve 17. Two clamping plates 29 are connected to the lower side of the handle sleeve 17. Both ends of the axle pins of the blocking lever block and the prying lever block pass through the two clamping plates and are fixed. There is an appropriate gap between the clamping plates and the blocking lever block and the prying lever block. In order to facilitate the installation of the blocking lever block and the prying lever block, the right end of the handle sleeve 17 and the two clamping plates 29 can be fixed on a disc plate 26 to form a removable structure, as shown in Figure A. The bottom shell surface of the seat shell 15 is made into an annular plate 28 that matches the disc plate, which acts as a flange. Connect the disc plate 26 and the annular plate 28 together at the positions shown in the figure with three screws 27, and then the blocking lever block and the prying lever block can be installed outside and then connected to the annular plate 28 on the right side of the seat shell 15. Subsequently, the outer end of the lever handle 9 is connected to the lower end of the lifting frame 8. The cover shell 20 has been removed during installation. The bottom plate 19 can be made integrally with the annular plate or can be welded and then polished smoothly.

[0039] In Figure C, the structure of the disc plate and the annular plate in Figure A is omitted, and it intuitively shows the process of the blocking block controlling the large, medium, and small water flows. It is Figure 5 In Figure F, the blocking block 4 in the figure has blocked on the lower edge of the ring opening 13, which means the seat body has been turned to the large water flow position and the faucet is in the water discharging state. Here, in order to centrally display the comparison of the positions of the blocking block 4 at the small, medium, and large water levels, the dotted line positions of the blocking block at the medium and small water levels are drawn successively to the left of the solid line position of the blocking block. It can be directly seen that when the blocking block swings leftward from the solid line position to the dotted line position of the medium water flow, the water flow becomes the medium water flow. When the blocking block moves leftward from the dotted line position of the medium water flow to the dotted line position of the small water flow, the water flow becomes the small water flow. Conversely, when the blocking block moves from the dotted line position of the small water flow on the left to the dotted line position of the medium water flow in the middle, and then to the solid line position in the figure, the water flow changes from the small water flow to the medium water flow, and similarly, it can change to the large water flow position.

[0040] Figure 7 In the figure, it shows the installation structure diagram of each component in the front direction inside the handle box. In the figure, the cover shell is cut away in the front direction of the handle box, and the figure is described by taking the three-stage water flow as an example. The button one 36, the button two 38, the button three 40, and the lifting frame 8 are all installed between the bottom plate 19 and the cover shell 20 of the handle box.

[0041] Figure 8 In the figure, it is Figure 7 The working process diagram of the inclined plane lifting device in the figure. The following is described in combination with Figure 7 、 Figure 8 together.

[0042] The button includes a key head 49 and a key bar 33. The key head and the key bar are collectively called the button. The key bar 33 is made into a square bar. The left end of the key bar is connected to the key head. The right end of the key bar is made into an inclined block 47. Figure 7A pair of lifting frames 8 are vertically installed on the middle right. Rollers 32 are installed on the upper and lower parts of each pressing bar. The function of rollers 32 is to make the friction of the pressing bar 33 very small when it moves left and right, reducing resistance. Figure 8 In the middle, a return spring 37 and a spring stopper 43 are installed on the top. The spring stopper 43 is fixed on the bottom plate 19 of the handle box. A core shaft 42 is fixedly connected to the spring stopper 43. The return spring 37 passes through the core shaft 42. A compression spring block 41 is connected to the top of the push bar 33. A through hole is opened in the compression spring block 41, and the core shaft 42 passes through the through hole of the compression spring block. Three square openings are opened on the left side shell 39 of the handle box, and the push bar 33 is installed in the square opening of the side shell 39. Figure 8 In the first figure, the lower part of the pressing bar is connected to a limited block 34. The left side of the limited block 34 is blocked by the limited pier 35 on the bottom plate. At this time, the pressing bar has moved to the left in the figure under the action of the return spring 37 and stretched out to the position, that is, the button is naturally released.

[0043] Figure 7 In the embodiment, the lifting frame 8 is divided into an upper lifting frame and a lower lifting frame. The lower end of the lower lifting frame is hingedly connected with the end of the trigger 9 installed in the seat body extending out of the bottom plate. Figure 7 The position of the connector 21 is marked in the figure. The upper and lower lifting frames are collectively referred to as lifting frames 8. Rollers 32 are also installed on both sides of the lifting frame 8 to guide the two sides of the lifting frame so that the resistance during the lifting and lowering process is very small. The axle pins of the rollers are inserted into the corresponding axle pin holes on the bottom plate of the handle box and the cover shell and fixed. Guide frames 44 are installed at the upper and lower middle positions of the lifting frame to enable the lifting frame to maintain appropriate sliding space with the bottom plate. The pressing bar 33 and the lifting frame 8 are installed vertically. The position of the inclined block 47 at the right end of each pressing bar on the lifting frame 8 is provided with an inclined panel 45 and a flat panel 46. Figure 7 The middle figure is an enlarged view of the D direction in the figure A, which is used to show the structure and installation of the inclined panel and the flat panel. The inclined panel is made into one piece with the flat panel and the bracket, and can be formed by one-step molding of engineering plastics or cast with aluminum alloy. The angle between the inclined block at the right end of the push bar on the buttons 1, 2, and 3 and the upper surface of each push bar, that is, the inclination with the horizontal plane, is the same as the inclination of the inclined panel 45 on the bracket, which is hereinafter referred to as the matching angle. However, the matching angles of the inclined block 47 at the end of the push bar of the buttons 1, 2, and 3 and the corresponding inclined panel on the bracket, that is, the three matching angles, are different. Figure 7 As can be seen, the matching angle corresponding to button 3 is the largest, which is called small-speed water flow. The matching angle corresponding to the middle button 2 is smaller than that of button 3, which is called medium-speed water flow. The matching angle corresponding to the bottom button 1 is the smallest, which is called large-speed water flow. Figure 7In the figure, Button 1, Button 2, and Button 3 are all in the released state, and each pressing bar is in the state of being blocked and returned to the left position as shown in the figure. The inclined blocks on the right side of each pressing bar are also in the state of being returned to the left position. At this time, the lifting frame has descended to the end position under the action of the return torsion spring 57 of the stopper in the seat body through the lever handle. At this time, the inclined plane of the inclined block at the right end of each pressing bar has just come into contact with the inclined plane on the corresponding inclined panel that has descended and has not yet been pushed to the right.

[0044] Figure 8 In Figure B, when the button is pressed, the pressing bar 33 makes the inclined block 47 move horizontally to the right below the corresponding inclined panel 45. Thus, the upward component force generated by the inclined block acting on the inclined panel causes the inclined panel and the lifting frame to rise by a set height. When the inclined block moves to the right until the upper plane at the right end of the pressing bar is just below the corresponding flat panel, the lifting frame is then held by the upper plane at the right end of the pressing bar. At the moment when the finger of the user pressing the button has not been released, the lifting frame is temporarily locked and cannot descend at this time. In the figure, when the button is pressed to the end and has not been released yet, the compression spring block 41 on the pressing bar compresses the return spring 37 and compresses to the right. The bottom plate and the cover of the handle box are connected by a cover screw 31, one on the upper and lower sides respectively. A notch is provided on the side shell where the pressing bar extends out of the left side of the handle box. The method of buckling the cover and the bottom plate is the prior art and will not be described here.

[0045] Figure 9 It is a diagram of the operation method of the button and the handle box.

[0046] Figure 9 In Figure A and Figure B, it is a diagram of how to press the button. In Figure A, it is the side of the handle box 6 where the button is located, facing away from the paper surface, that is, the front shell of the handle box cannot be seen. In Figure B, it is possible to see both the side of the handle box where the button is located and the front of the handle box. The button is pressed as shown in the figure: When pressing the middle button on the handle box, that is, the medium-grade button ( Figure 7 Button 2 38 marked in the figure), place the thumb 50 on the position of the medium-grade button, and at the same time, place the other fingers on the other side of the handle box. Then pinch both sides of the fingers towards the middle at the same time, that is, press the medium-grade button to the end. This operation method avoids the problem that when pressing the button, the handle box 6 deflects towards the other side when pressing from one side of the handle box. In Figure A and Figure B, the water control seat is still in the closed state.

[0047] In Figure C, when you want to turn on the faucet, pinch the handle box 6 and then gently pull the handle box outward, i.e., to the right in the figure. The handle box will then rotate outward until it reaches the stopping position. At this time, the faucet will release medium - flow water. You can then release your hand. The handle box will remain in the skewed - to - the - right position in the figure and continue to release water. When you want to change from medium - flow water to high - flow water, simply keep the position in Figure C unchanged, press the high - flow key again, i.e., key 1 - 36, and then gently pull the handle box to the right again until it is blocked and then release your hand. At this time, high - flow water will be released.

[0048] For existing cold - and - hot water faucets, people are used to the fact that turning the handle to the left is for hot water and turning the handle to the right is for cold water. Users can turn the handle box to the left or right in Figures A and B according to the cold or hot water they choose, or turn the handle box to the left or right in the position of Figure C. When the water release is complete and you want to turn off the faucet, simply push the front of the handle box inward to turn off the faucet. This is the same as the traditional usage method. After people use it several times, when pressing the button, their fingers will quickly press the button on the handle box and the other side of the handle box at the same time, and they can complete the operation with just a reach of their hand. The button can be set on either of the two side surfaces of the handle box.

[0049] Figure 10 In [diagram], it is the working principle diagram of each component inside the handle box when controlling water flow at each gear.

[0050] Figure 10 In Figure A of [diagram], it is the low - flow control process diagram. In Figure B, it is the medium - flow control process diagram. In Figure C, it is the high - flow control process diagram. The following is an explanation in combination with Figure 5 and Figure 7 for illustration.

[0051] Figure 10 In Figure A of [diagram], it is the low - flow, i.e., third - gear, control process. At this time, the low - flow key, i.e., key 3 - 40, has been pressed and not released yet. The inclined block 47 at the right end of the pressing bar of key 3 - 40 has already acted on the corresponding inclined plane 45 and flat plane 46 on the lifting frame, and the lifting frame has been raised by a set height. At this time, the upper plane at the right end of the pressing bar is already below the flat plane, and the lifting frame cannot move downward. This is exactly the same as what is shown in Figure 8 Figure B. The operation of pressing key 3 is the same as the operation method of pressing key 2 in Figure 9 Figure A. When pressing key 3, the lifting frame will pull the lever 9 to rotate upward by an angle corresponding to the low - flow gear. The stop block will be simultaneously controlled to rotate to the low - flow angle. As shown in Figure 5 Figure A in [diagram], the lever rotates from the dotted - line position to the solid - line position, i.e., the preset position of the low - flow gear.

[0052] After the user presses the button in place, immediately and smoothly pull the handle box backward, as shown in Figure 9 Figure C in [diagram]. This will cause the seat body to rotate downward. During the downward rotation of the seat body, Figure 5The stopper shown in the figure immediately leans against the lower edge of the ring opening and cannot rotate further. Then, a small amount of water is released. The user can immediately release the finger. The action of pulling the handle box outwards is the same as the usage method of the traditional cold and hot water switch.

[0053] Similarly, when it is necessary to open the second gear, that is, the medium gear water flow, as shown in Figure 10 Figure B of. The user presses the button two 38 in place. Without releasing the hand, the user smoothly pulls the handle box outwards in place and then can release the hand. The second gear water flow is released. In this short moment, the control process, the preset process of the stopper, and the process of the seat body rotating downwards and being blocked and stopped are all the same as Figure 10 the process of opening the third gear and discharging water in Figure A of.

[0054] Similarly, Figure 10 as shown in Figure C of, the operation process, control, preset gear, and the process of the seat body rotating downwards and being blocked and stopped when pressing the button one 36 to open the first gear, that is, the large gear water flow, are also the same as Figure 10 the process of opening the third gear, that is, the small gear and discharging water in Figure A of.

[0055] Because the inclined surface angles of the inclined blocks at the inner ends of the pressing strips of the first, second, and third gear buttons and the corresponding inclined panels on the lifting frame are different, when pressing the first, second, and third gear buttons, although the rightward travel of each gear pressing strip is the same, the height of the lifting frame lifted is different. From Figure 10 Figures A, B, and C of, and Figure 8 , Figure 7 it can be seen that the lifting heights of the lifting frames of each gear are different during the process of opening the third gear, second gear, and first gear and discharging water. The lifting frame of the third gear rises the highest, the lifting frame of the second gear rises less than that of the third gear, and the lifting frame of the first gear rises the least. Since when pressing the buttons of each gear, the different lifting heights of the lifting frame are controlled, the rotation angle of the lever is also controlled, that is, the different rotation angles of the stopper are controlled, and the different rotation angles of the water control seat turning outwards during water discharge are also controlled, so as to achieve the purpose of controlling different water flow sizes.

[0056] Figure 11 In, it is another embodiment diagram using a roller to replace the inclined block at the inner end of the pressing strip and the guiding device of the pressing strip. In Figures A and B, the return spring of the pressing strip selects a torsion spring 57, which has the same structure as the widely used torsion spring at present. The wire winding of the torsion spring is fixed on the bottom plate 19 with a pin 54. An inclined opening 52 is opened from top to bottom in the middle of the pressing strip. One end of the torsion spring wire is blocked by the blocking nail 55 fixed on the bottom plate, and the other end of the torsion spring wire passes through the inclined opening on the pressing strip. The tension of the torsion spring always makes the pressing strip move towards the left arrow direction. In Figure A, it is the state before the button is pressed. The pressing strip has already returned to the left under the action of the torsion spring, and the left side of the torsion spring is blocked and limited by the blocking pier 53. In Figures A and B, the up and down guiding of the pressing strip still adopts the roller guiding method, which is the same as Figure 7 , Figure 8The structures in the middle are the same. In Figures A and B, a roller 56 is installed at the right end of the bar 33 to replace Figure 7 , Figure 8 , Figure 10 the inclined block 47 in. In Figure A, it is the state where the button has not been pressed in. The outer wheel surface on the upper right side of the roller 56 is exactly stopped at the upper left position of the corresponding inclined panel on the lifting frame.

[0057] In Figure B, it is the state where the button has been pressed in place and not released yet. At this time, under the action of the button being pressed in, the right side surface above the wheel of the roller presses against the inclined panel on the right side, and the roller moves and rotates while moving to the right. In this way, it is less than the frictional resistance in Figure 7 , Figure 8 where the inclined block forces the inclined panel to move upward. It also makes the force required to press the button smaller than when using the inclined block. In Figure B, the roller has rolled over the inclined surface of the inclined panel, and the upper vertex of the roller has abutted against the lower surface of the flat panel. At this time, at the moment when the button has not been released, the lifting frame 8 cannot descend, which is the same as the situation shown in Figure B in Figure 8 .

[0058] Figure 11 In Figure C, the right end of the bar still uses the inclined block structure, but the guiding device of the bar uses the structure of a square sliding shell 58. The sliding shell 58 is fixed on the bottom plate 19 of the handle box, and the torsion spring 57 is still used as the return spring of the bar 33. The structure and installation method of the torsion spring are the same as those of the torsion spring installation structure in Figures A and B, except that notches 25 are opened at the corresponding positions on the upper and lower shell plates of the sliding shell 58. Pass the torsion spring wire through the notch opened on the upper surface of the sliding shell and then insert it into the corresponding inclined notch 52 of the bar. When the button is pressed, the bar pushes the torsion spring wire to swing to the right, and the inclined block at the right end of the bar acts on the inclined panel to lift the lifting frame by a certain height to the right. This is the same as the process in Figure B in Figure 8 .

[0059] In Figure D, it is an enlarged view in the D direction of Figure C, and it is another manufacturing structure diagram of the inclined panel, flat panel, and lifting frame. In the figure, the inclined panel and the flat panel are replaced by corresponding Figure 7 , Figure 8 notches with inclined surfaces 59 and flats 60 opened at the positions of each inclined panel and flat panel, which is equivalent to widening the part of the lifting frame 8 without the inclined panel 45 and flat panel 46 in Figure 7 , Figure 8 and leaving an opening 61 for the inclined block to pass through below each group of inclined surfaces and flats. When the lifting frame is made of plastic, the thick part can be made into a shell structure.

[0060] When the user does not press any button, the water control seat can be used as an existing handle seat. Pull the handle box out to the end to open the faucet at the maximum water flow, and push the handle box inward to reduce the water flow or turn off the faucet switch.

[0061] For users, it is necessary to determine how many gears of the switch should be turned on first to let out water, which should be determined according to the water pressure conditions in different regions and different floors of high-rise buildings. For families and work units, for a long time, the water pressure has been relatively stable in the vast majority of cases. In this case, after using it several times, users will be familiar with the water flow of each gear. So in the future, when letting out water, they will reach out and turn on the appropriate gear, and in most cases, the water let out will be appropriate at once. Occasionally, when the water pressure changes greatly temporarily, they will shift gears to let out water. Some users are used to using water to wash hands, fruits, vegetables, especially tableware such as bowls and basins. For items of different sizes, they can determine which gear of water flow should be directly turned on according to experience, and can turn on the switch appropriately at once.
