Description

Technical Field

[0001] The present invention relates to the technical field of faucets, and in particular, to a water-saving multifunctional faucet and its assembly process. Background Art

[0002] At present, faucets on the market are divided into two types: manual and automatic. The automatic faucet, that is, the infrared induction faucet, has been widely used due to its good water-saving effect.

[0003] However, the current induction faucets still have deficiencies. Since the water output is automatic and constant, for some induction faucets in office buildings or shopping malls, the most frequent use is for handwashing, and the water output requirement for handwashing is not high. If the water output is large, not only is it easy to splash water, causing water accumulation and waste around the washbasin, but also most of the water flow cannot be fully utilized, greatly reducing its own water-saving effect.

[0004] In view of the above defects existing in the prior art, it is necessary to further improve it to make it more practical to meet the actual use situation. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0016] A sealing rubber ring is fixedly adhered to the outer wall of the piston ring, and it is hermetically fitted with the inner wall of the water outlet pipe through the sealing rubber ring;

[0017] The distance between the centers of the water outlet hole and the sealing plate is greater than the diameter of the water guide pipe.

[0018] Further, a guide rod slidably connected to it penetrates through the partition plate. The guide rods are distributed in a rectangle. One end of the guide rod is welded to the movable plate, and the other end is sleeved with a mounting ring welded to it;

[0019] The center of the side of the movable plate not connected to the guide rod is welded to a first magnet block through a connecting rod. The diameter of the movable plate is greater than the inner diameter of the through hole, and the two share the same axis;

[0020] A second elastic spring is sleeved on the guide rod between the mounting ring and the partition plate. Both ends of the second elastic spring are welded to the mounting ring and the partition plate, and the second elastic spring is made of stainless steel.

[0021] Further, the first magnet block and the second magnet block are horizontally aligned, and through grooves are provided on the side walls of the first mounting box opposite to the two ends horizontally. Glass plates are hermetically adhered in the through grooves, and the side lengths of the glass plates are greater than the diameters of the first magnet block and the second magnet block.

[0022] Further, a damping cylinder is fixedly adhered to the inner wall of the fixed cylinder, and the movable rod passes through the damping cylinder and fits with the inner wall of the damping cylinder. The damping cylinder is made of butyl rubber.

[0023] Further, a third elastic spring is sleeved on the movable rod, and both ends of the third elastic spring are welded to the second magnet block and the second mounting box, and the elastic force of the third elastic spring is less than the magnetic force between the second magnet block and the first magnet block.

[0025] Further, the inner diameters of the third threaded connector and the through hole are the same, the inner diameters of the first threaded connector and the second threaded connector are the same, and the cross-sectional area of the third threaded connector is half of the cross-sectional area of the first threaded connector.

[0026] Further, the first mounting box and the second mounting box are fixedly connected by bolts, and a fixing gasket welded to it is sleeved on the outer wall of the top end of the first mounting box, and fixing holes are provided on the fixing gasket;

[0027] One side of the second mounting box that fits the first mounting box is open.

[0028] A water-saving multifunctional faucet assembly process includes the following steps:

[0029] 1. Install the faucet body, the first control box and the first mounting box on the washbasin or the wall.

[0030] 2. Connect the first threaded connector on the first mounting box to the water inlet end of the faucet body through the first connecting pipe, and connect the second threaded connector on the first mounting box to the water outlet end of the first control box through the second connecting pipe;

[0031] 3. Connect the water inlet end and the water outlet end of the second control box to the third threaded connector and the fourth threaded connector respectively;

[0032] 4. Then bolt-fix the second mounting box to the first mounting box, and connect the water inlet end of the first control box to the external water network;

[0033] 5. Finally, connect the first infrared sensor and the second infrared sensor to the external power grid and power on for operation.

[0034] Through the water-saving multifunctional faucet and its assembly process of the present invention, the beneficial effects are as follows:

[0035] The present invention is provided with two groups of infrared control systems, namely the first infrared sensor and the first control box, and the second infrared sensor and the second control box. At the same time, a first mounting box is also provided. When in normal use, the first infrared sensor detects that a person is approaching, and through the first control box, the water flow is introduced into the inner wall of the first mounting box, and finally the water flows out through the water outlet end;

[0036] At the same time, since the inner part of the first water guide cavity in the first installation box is divided into a first water guide cavity and a second water guide cavity, after it is opened, the water flow can only be first introduced into the first water guide cavity, and then enters the second water guide cavity through the flow limiting of the through hole. In this way, the water output is reduced to half of the normal water output. Furthermore, the water flow flowing out through the water outlet end is relatively small. When washing hands with this water flow, the water utilization rate is high, and the water will not splash out, greatly improving the overall water-saving function;

[0037] After the water has flowed out for a period of time, a part of the water flow in the first water guide cavity will be introduced into the second water guide cavity through the second control box. In this way, all the water flow in the first water guide cavity will be gathered in the second water guide cavity, and the normal water output can be restored. At this time, the water output flow returns to normal, and operations such as filling a kettle with water can be carried out;

[0038] After this faucet is opened, it can achieve low-water-output for several seconds. During this period, operations with low requirements for water output such as washing hands can be carried out. After several seconds, the water flow returns to normal, which is convenient for operations with high requirements for water output such as filling water. Through this setting, the defect of the constant water output of the current induction faucet can be improved;

[0039] The water outlet end part is a water outlet pipe and a water outlet head. When the faucet stops discharging water, a sealed structure is formed between the water outlet pipe and the water outlet head, thereby avoiding the dripping of the remaining water inside after the faucet is closed, further improving the water-saving effect and enhancing the overall functionality of the faucet; BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0049] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0050] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0051] Please refer to Figure 1-7 , the present invention provides a technical solution: a water-saving and multifunctional faucet, including a faucet body 1, on which a water outlet end and a first infrared sensor are provided. The first infrared sensor and the first control box 3 are electrically connected. The top wall, bottom and two outer walls of the first installation box 4 are respectively welded and connected with a first threaded connector 6, a second threaded connector 7, a third threaded connector 20 and a fourth threaded connector 21;

[0052] It further includes a first installation box 4 and a second installation box 5. The second infrared sensor 32 and the second control box 19 are bolt-fixed on the inner wall of the second installation box 5. The second control box 19 and the second infrared sensor 32 are electrically connected;

[0053] Such as Figure 1 and Figure 2As shown, during installation, the faucet body 1, the first control box 3, and the first installation box 4 can be installed on the washbasin or the wall first. Then, the water outlet end of the second control box 19 is thread-sealedly connected to the third threaded connector 20 through the third connecting pipe 22, and its water inlet end is thread-sealedly connected to the fourth threaded connector 21 through the fourth connecting pipe 23. After the above is completed, the second installation box 5 is fixed on the first installation box 4;

[0054] Next, the first threaded connector 6 is thread-sealedly connected to the water inlet end of the faucet body 1 through the first connecting pipe 8, and the second threaded connector 7 is thread-sealedly connected to the water outlet end of the first control box 3 through the second connecting pipe 9. Finally, the water inlet end of the first control box 3 is docked with the external water network, and at the same time, the first control box 3 and the second control box 19 are connected to the power grid, thus completing the overall assembly operation;

[0055] As Figure 2 shown; a partition 10 is welded and connected to the inner wall of the first installation box 4. The partition 10 divides the interior of the first installation box 4 into two sealed cavities, namely the first water guide cavity 11 and the second water guide cavity 12. And a through hole 13 is opened on the partition 10. When the first infrared sensor detects a human body, it will transmit a signal to the first control box 3. After receiving the signal, the first control box 3 opens the solenoid valve according to the specified instruction. In this way, the water flow in the water network can pass through the first control box 3, and then flow into the first water guide cavity 11 inside the first installation box 4 through the second connecting pipe 9. Then, it enters the second water guide cavity 12 through the through hole 13, and finally flows into the faucet body 1 through the first connecting pipe 8 and flows out from the water outlet end, thus completing the entire water outlet operation;

[0056] The inner diameters of the third threaded connector 20 and the through hole 13 are the same, and the inner diameters of the first threaded connector 6 and the second threaded connector 7 are the same. Moreover, the cross-sectional area of the third threaded connector 20 is half of the cross-sectional area of the first threaded connector 6. The inner diameters of the third threaded connector 20 and the through hole 13 are set such that when the water flow in the first water guide cavity 11 enters the second water guide cavity 12 through the through hole 13, due to the sudden reduction of the water inlet channel, the flow rate of the water flow is reduced by half. In this way, the water output flowing out from the water outlet end is only half of the normal water output. Therefore, when the faucet body 1 is opened, a low-water-output water outlet operation will be carried out first. At this time, when performing operations such as washing hands, not only will there be no splashing phenomenon, but also the utilization rate of the water flow will be improved, which is beneficial to improving the overall energy saving;

[0057] As Figure 2 、 Figure 4 shown, a guide rod 17 that is slidably connected to it penetrates through the partition 10. The guide rods 17 are distributed in a rectangular shape. One end of it is welded and connected to the movable plate 14, and the other end is sleeved with an installation ring that is welded and connected to it;

[0058] At the center of the side of the movable plate 14 that is not connected to the guide rod 17, it is welded and connected to the first magnet block 16 through the connecting rod 15. The diameter of the movable plate 14 is larger than the inner diameter of the through hole 13, and the two share the same central axis;

[0059] A second elastic spring 18 is sleeved on the guide rod 17 between the mounting ring and the partition plate 10. Both ends of the second elastic spring 18 are welded and connected to the mounting ring and the partition plate 10, and the second elastic spring 18 is made of stainless steel. During the process that the water flow in the first water guide cavity 11 enters the second water guide cavity 12 through the through hole 13, since the movable plate 14 blocks the through hole 13 at this time, the water flow pressure inside the first water guide cavity 11 will gradually increase and can push the movable plate 14 open. The movable plate 14 moves horizontally on the partition plate 10 through the guide rod 17, and can drive the first magnet block 16 to move synchronously through the connecting rod 15. The mounting ring can move synchronously with the guide rod 17, so that the second elastic spring 18 can be compressed during the movement. When the first control box 3 is disconnected from the external water network, the water flow pressure inside the first water guide cavity 11 decreases. At this time, under the elastic force of the second elastic spring 18, it can drive the movable plate 14 to reset and block the through hole 13 again;

[0060] As Figure 2 、 Figure 3 and Figure 5 shown, a fixed cylinder 26 welded to the side wall of the second installation box 5 penetrates through. A second magnet block 29 slidably connected to it is arranged inside the fixed cylinder 26. The second magnet block 29 and the first magnet block 16 are of the same name magnetic poles. A damping cylinder 27 is fixedly adhered to the inner wall of the fixed cylinder 26, and the movable rod 28 passes through the damping cylinder 27 and fits with the inner wall of the damping cylinder 27. The damping cylinder 27 is made of butyl rubber. A third elastic spring 31 is sleeved on the movable rod 28. Both ends of the third elastic spring 31 are welded and connected to the second magnet block 29 and the second installation box 5, and the elastic force of the third elastic spring 31 is less than the magnetic force between the second magnet block 29 and the first magnet block 16;

[0061] The first magnet block 16 and the second magnet block 29 are horizontally aligned, and through slots 24 are formed on the side walls of the first mounting box 4 that are horizontally opposite to both ends. A glass plate 25 is hermetically bonded in the through slots 24. The side lengths of the glass plate 25 are both greater than the diameters of the first magnet block 16 and the second magnet block 29. The second magnet block 29 is in contact with the glass plate 25. When the first magnet block 16 moves horizontally and approaches the glass plate 25, since the glass plate 25 does not block the magnetic force, a repulsive force will be generated between the first magnet block 16 and the second magnet block 29. Under the action of the repulsive force, the second magnet block 29 will be pushed to move horizontally. The second magnet block 29 can drive the movable rod 28 to move quickly in the fixed cylinder 26. The setting of the damping cylinder 27 can cause a frictional force to be generated between the movable rod 28 and the damping cylinder 27 when the movable rod 28 moves horizontally. As a result, the movement of the movable rod 28 is hindered, forcing the quickly moving movable rod 28 to change into a slow movement. In this way, the second magnet block 29 can also move slowly. By changing the length of the damping cylinder 27, the frictional force between the damping cylinder 27 and the movable rod 28 can be adjusted to ensure that the movable rod 28 can move slowly without stopping due to excessive frictional force. The time for the second magnet block 29 to move slowly is the time for the faucet body 1 to discharge water with a low water volume. By changing the frictional force, the length of the low water volume discharge time can be controlled, and the time can be controlled within about 5S. In this way, simple operations such as washing hands can be completed within this time without affecting normal use. When the handwashing operation is completed within 5S, the faucet body 1 will close, and thus normal water volume discharge will not occur, thereby improving the water-saving effect;

[0062] When the movable rod 28 moves, it will compress the third elastic spring 31 through the second magnet block 29. After the first magnet block 16 and the second magnet block 29 are separated, the movable rod 28 can slowly reset and drive the second magnet block 29 to contact the glass plate 25 again, facilitating the next operation;

[0063] A horizontal plate 30 is fixedly bonded to the side wall of the second magnet block 29. The horizontal plate 30 and the second infrared sensor 32 are in the same vertical plane, and the distance between them is less than the working range of the second infrared sensor 32. And the working range of the second infrared sensor 32 is less than the distance between it and the top of the second installation box 5. The working range of the second infrared sensor 32 is designed so that it will not sense the second installation box 5. Thus, when there is no object approaching, the second infrared sensor 32 will not work. When the second magnet block 29 moves, it will drive the horizontal plate 30 on its side to move synchronously. In this way, when the horizontal plate 30 moves directly above the second infrared sensor 32, the second infrared sensor 32 will receive a signal and transmit the signal to the second control box 19. After receiving the signal, the second control box 19 opens the solenoid valve according to the specified instruction. At this time, part of the water flow in the first water guide cavity 11 enters the second control box 19 through the fourth connecting pipe 23, and then enters the second water guide cavity 12 through the third connecting pipe 22. Thus, part of the water flow in the first water guide cavity 11 enters the second water guide cavity 12 through the through hole 13, and part enters the second water guide cavity 12 through the second control box 19. After the two water flows converge, the normal water output flow rate can be restored and flows out through the faucet body 1. In this way, after the faucet body 1 has a short period of low water output, it can immediately restore the normal water output volume, which is convenient for operations such as filling water;

[0064] As Figure 6 and Figure 7 shown, the water outlet end includes a water outlet pipe 101 and a water outlet head 102. A sealing plate 111 and a limiting ring 113 are welded to the inner wall of the water outlet pipe 101, and the sealing plate 111 is provided with water outlet holes 112 distributed in a ring shape;

[0065] One end of the water outlet head 102 facing the water outlet pipe 101 is welded and connected to one end of the water guide pipe 122 and is in communication. And the other end of the water guide pipe 122 is inserted into the water outlet pipe 101 and is welded and connected to the piston ring 121 and is in communication,

[0066] The outer diameter of the water conduit 122 is consistent with the inner diameter of the limit ring 113, and the outer wall of the water conduit 122 is in contact with the limit ring 113 without being fixed; the piston ring 121 is welded to the limit ring 113 through the first elastic spring 114. When the water outlet of the faucet body 1 occurs, the water flow pressure inside the water outlet end will increase, and the water flow can push the piston ring 121 to move through the water outlet holes 112. The piston ring 121 drives the water outlet head 102 to move synchronously through the water conduit 122. At this time, the piston ring 121 is separated from the sealing plate 111, and the water flow can flow out from the water outlet head 102 through the water conduit 122 to realize the water outlet operation. During this process, the movement of the piston ring 121 will compress the first elastic spring 114. When the water outlet of the faucet body 1 stops, the water flow pressure inside the water outlet end disappears. Under the elastic force of the first elastic spring 114, it can drive the piston ring 121 to fit with the sealing plate 111 again, which can disconnect the water outlet pipe 101 and the water outlet head 102 and prevent the remaining water droplets in the water outlet pipe 101 from dripping out;

[0067] A sealing rubber ring is fixedly bonded to the outer wall of the piston ring 121, and it is in sealed contact with the inner wall of the water outlet pipe 101 through the sealing rubber ring; the distance between the centers of the water outlet holes 112 and the sealing plate 111 is greater than the diameter of the water conduit 122. The piston ring 121 can form a sealing structure with the water outlet pipe 101 through the sealing rubber ring, so that the water flow pressure can all act on it and it can be quickly pushed; at the same time, after the piston ring 121 is in contact with the sealing plate 111, the piston ring 121 will block the water outlet holes 112, so that the two form a sealing structure, which can disconnect the water outlet pipe 101 and the water outlet head 102.

[0068] The first mounting box 4 and the second mounting box 5 are bolted together, and a fixing gasket 33 welded to it is sleeved on the outer wall of the top of the first mounting box 4, and fixing holes are provided on the fixing gasket 33; the surface of the second mounting box 5 in contact with the first mounting box 4 is open. The open design of the second mounting box 5 facilitates the docking of the second control box 19 with the third connecting pipe 22 and the fourth connecting pipe 23. The design of the fixing gasket 33 facilitates the installation and fixation of the first mounting box 4;

[0069] The circuit connection relationship and the internal structure between the first infrared sensor and the first control box 3, the second control box 19 and the second infrared sensor 32 are all prior arts. For example, for the induction faucet of the brand: Di, it is a mature technical product on the market, so the applicant will not elaborate too much.
