Therefore, the valve opening adjustment screw 45 is configured to be able to move downward or upward by rotating the head 61. The operation of the faucet opening/closing device 23 according to this embodiment will be explained below. In this case, the valve 19 closes the water inlet 14 as shown in FIG. A description will be given starting from a state in which the tap 11 of the water supply lO is blocked. That is, as shown in FIG. 1, when the valve 19 closes the inlet 14, the valve opening/closing rod 44 is in the upper position, the arm 42 is also in the upper position, and the second The cam 3 provided on the driven gear 34 of
8 is in the upper position and is in contact with the lever part 40 that controls the contact part 84, and the protrusion 37 is in the lower position. When discharging water from the faucet 11 of the water supply 10 using the faucet opening/closing device 23 configured as described above, the user must first check the sensor hole 53 formed on the side surface of the faucet outer mounting portion 22. A hand or the like is placed near , and the photosensor 49 detects the hand. When the photosensor 49 detects the user's hand, etc., the photosensor 49 sends a predetermined signal to the control board 27, and the control board 27 supplies power from the battery 25.25 to the drive motor 28.
supply to In this way, if power is supplied to the drive motor 28 from the battery 25.25. The drive motor 28 operates to rotate the output shaft 29 and the driving gear 31 provided at the lower end of the output shaft 29 . When this driving gear 31 rotates, the first driven gear 32 that meshes with the driving gear 31 also rotates, and the transmission gear 33 attached to the shaft portion 35 of this first driven gear 32 also rotates. This causes the second driven gear 34 that meshes with the transmission gear 33 to rotate. When this second driven gear 34 rotates,
The cam 38 eccentrically attached and fixed to the shaft portion 36 of the second driven gear 34 also rotates downward in FIG. The arm 42 that is in pressure contact is gradually pushed down. And in this case. A protrusion 37 provided at a position opposite to the cam in the diametrical direction of the second driven gear 43 gradually rotates upward in the opposite direction to the cam 38 . Thereafter, when the cam 38 reaches the lowermost position as shown in FIG.
0 and presses the lever 40 upward. In this case, the lever 40 bends upward and presses the contact body 83 projecting below the limit switch 39 upward. This upward movement of the contact body 83 activates the limit switch 39, which cuts off the power supply from the battery 25, 25 to the drive motor 28. As a result, the first driven gear 32. Transmission gear 33 and second
The driven gear 34 stops rotating, and the cam 38 stops at the lowest position. Therefore, the arm 42 also stops at the lowest position, and as the arm 42 rotates downward about the shaft 43, it gradually moves downward against the biasing force of the spring 58. The valve opening/closing rod 44 also stops at its lowermost position. Therefore, the valve 19 provided at the lower end of the valve opening/closing rod 44 completely opens the inlet 14, and the water stored in the supply side water passage 12 is drained from the faucet opening/closing valve seat. 13 into the faucet inner insertion part 2o from the inlet 14, and flows through the flow path 18 to the outlet 17.
Flows out from the faucet inner insertion part to the outside of the faucet side water passage 16.
Water is discharged outward from the spout 62 of the water supply 10 through the water supply. Next, a case will be described in which the faucet 11 of the water supply 10 is closed using the faucet opening/closing device 23 according to this embodiment. When the user wants to block the water flowing out from the faucet 11 of the water supply 10, the user re-inserts the sensor into the sensor hole 53 provided in the faucet outer attachment part 22 in the same way as when the water is flowing out.
approach. In this case, similarly to the case described above, the photosensor 49 operates to supply power from the battery 25.25 to the drive motor 28. When power is supplied to the drive motor 28 and the battery 25.25, the output shaft 29 and the driving gear 31 rotate in the same manner as described above, and the first driven gear 32 and the transmission gear 33 that are interlocked with the driving gear 31 rotate. And the second driven gear 34 rotates. As a result, the cam 38 attached to the second driven gear 34 and currently located at the lowest position gradually begins to rotate about the shaft portion 36 as the second driven gear 34 rotates. , starts to rise gradually. Further, in this case, the protrusion 37 attached to the second driven gear 34 at a diametrically opposite portion begins to rotate and descend from the uppermost position, contrary to the cam 38. As the cam 38 rises, the arm 42, which is always in pressure contact with the circumferential surface of the cam 38, gradually begins to rotate upward about the shaft 43, and comes into pressure contact with the lower surface of the arm 42. The valve rod 44 also begins to rise gradually. Therefore, the valve 19 fixedly attached to the lower end of the valve rod 44 also gradually begins to close the inlet 14, and due to the rotation of the second driven gear 34, the cam 38
reaches the uppermost position, the peripheral surface of the cam 38 comes into contact with the lever part 40 that constitutes the contact part 84 provided at the lower part of the limit switch 39, and the lever part 40 bends and presses the contact body 83 upward. In this case, limit switch 39
is activated to stop supplying power from the batteries 25, 25 to the drive motor 28. In this way, when the power supply to the drive motor 28 is stopped, the operation of the drive motor 28 is stopped and the first driven gear 32. As a result of the rotation of the transmission gear 33 and the second driven gear 34 also stopping, the cam 38 stops moving at the uppermost position. In this case, the protrusion 37 is at the lowest position on the opposite side to the cam 38, but as shown in FIG.
is formed shorter than the cam 38, and the second driven gear 3
4. Since the amount of protrusion toward the rear surface is small, the arm 42 will not be pushed down without interfering with the arm 42. Therefore, as shown in FIG.
When the arm 42 reaches the uppermost position, the arm 42 reaches the uppermost position and stops moving, the valve opening/closing rod 44 reaches the uppermost position, and the valve provided at the lower end of the valve opening/closing rod 44 stops moving. 19 completely closes the inlet 14. By completely blocking the inlet 14 with this valve 19,
The inflow of water from the supply side passageway 12 to the water outlet side passageway 16 is stopped, and the outflow of water from the faucet 11 of the water supply lO is stopped. In addition, in the faucet opening/closing device 23 according to the present embodiment, if the battery 25, 25 or the like is exhausted and the faucet 11 cannot be opened/closed using the automatic valve opening/closing means 21, as shown in FIG. The user can open and close the faucet 11 using the manual valve opening/closing means 75. That is, in this embodiment, the manual valve opening/closing means 75
When opening and closing the faucet 11 using the faucet opening/closing device 23, the user places his/her hand on the rotating portion 51 formed in a hemispherical dome shape and is attached above the faucet opening/closing device 23, and rotates the faucet 11. That is, as shown in FIG. 4, the rotating part 51 is rotated so that the highest part 87 of the end cam 47 provided on the back side of the rotating part 51 formed in a hemispherical dome shape comes into contact with the driven rod 48. Rotate. When the user rotates the rotating portion 51 in this manner and the driven rod 48 follows the slope portion 89 of the end cam 47 and is located at the highest portion 87 of the end cam 47, the driven rod 48 The driven rod 48 is pressed downward while reaching from the lowest portion 88 to the highest portion 87, and by reaching the highest portion 87, the driven rod 48 is located at the lowest position. In this case, the lower end of the driven rod 48 is connected to the shaft portion 4 of the arm 42.
3, the arm 42 is pressed by the driven rod 48 and rotates downward about the shaft portion 43. In this case, since the upper end of the valve opening/closing rod 44 is in contact with the lower surface of the arm 42, as the arm 42 rotates downward about the shaft 43, The valve opening/closing rod 44 is pressed downward,
A valve 19 provided at the lower end of this valve opening/closing rod 44 opens the inlet 14 . Contrary to the above, if the user wants to close the water faucet 11 using the manual valve opening/closing means 70 and stop discharging water, the user rotates the rotating part 51 once and the driven rod 48 is rotated until it comes into contact with the lowest part 88 of the end cam 47 provided on the back side of the rotating part 51. In this way, when the user rotates the rotating part 51 until the driven rod 48 comes into contact with the lowest part 88, the driven rod 48 is inserted into the faucet inner insertion part 20. Since the coil spring 58 is pressed upward by the biasing force of the coil spring 58, the driven rod 48 moves upward due to the biasing force of the coil spring 58. The arm 42, which the lower end of is in contact with, also rotates upward about the shaft portion 43. Therefore, the valve opening/closing rod 44 whose upper end is in pressure contact with the lower surface of the arm 42 also has a coil spring 5.
The valve 19, which is provided at the lower end of the valve opening/closing rod 44, is moved upward by the urging force of the valve 8.
It will rise and block the inlet 14. Therefore, the inflow of water from the inflow port 14 is stopped, and the outflow of water from the spout 62 of the faucet 11 is stopped. Further, when the valve 19 is opened using the automatic valve opening/closing means 21 or the manual valve opening/closing means 75, the opening degree of the valve 19 is adjusted by operating the valve opening adjustment screw 45. and inlet 1
The inflow amount of water from 4 can be adjusted. In other words, when the valve opening degree is set to m nodes, the user:
The rotating part 51 attached to the upper part of the faucet outer attachment part 22 is removed to expose the head 61 of the valve opening adjustment screw 45. When it is desired to increase the amount of water flowing in from the inlet 14 by increasing the opening degree of the valve 19, the valve opening adjustment screw 45 is rotated using an appropriate tool such as a screwdriver, and the faucet is turned off. Advance the switchgear downward. In this way, when the valve opening mm screw 45 advances downward by rotating the head 61,
As described above, the lower end of the shaft portion 86 of the valve opening adjustment screw 45 is in contact with the upper surface of the gear case 41, so that the gear case 41 is As it advances downward, the shaft portion 35
It rotates downward around the center. When the gear case 41 rotates downward around the shaft portion 35 in this way, as shown in FIG. 5, the shaft portion 36 attached to the gear case 41 moves downward. The rotational position of the second driven gear 34 attached to the portion 36 is also displaced downward, and as a result, the cam 38 provided on the back side of the second driven gear 34 also operates further downward. becomes. Therefore, the arm 42 that is always in pressure contact with the cam 38 and forms the swinging cam device 78 also
As a result, the valve opening/closing rod 44 is pressed further downward than normal, and the valve 19 provided at the lower end of the valve opening/closing rod 44 is rotated further downward about the shaft portion 43. will be located lower than the normal position. Therefore, the distance between the upper slope portion 70 of the valve 19 and the peripheral edge of the inlet 14 is further increased, and the amount of water flowing from the inlet 14 is increased. Therefore, the amount of water flowing from the supply side passageway 12 to the spout side passageway 16 via the inlet 14 increases, and the amount of water flowing out from the spout 62 of the faucet 11 increases.

Therefore, in the faucet opening/closing device 23 according to the present embodiment, the faucet inner insertion portion is inserted into the water passage 12.16 provided in the faucet 11 and can control the water flow in the water passage. 20 and a faucet outer mounting part 22 in which a valve opening/closing means capable of opening and closing a valve for controlling the water flow are installed separately. Since the mounting part 22 is tightly sealed with a backing 56 as a sealing member, the faucet outer mounting part 22 is equipped with a valve opening/closing means 21.75.
Water in the water passages 12, 16 will not flow into the tank, and there will be no risk of failure even if it is used for a long period of time. In addition, when the faucet opening/closing device 23 according to this embodiment is attached to the water faucet 11, as shown in FIG. By loosening the backing nut 65 of the opening/closing handle 63, the faucet 11 is opened.
Since the faucet is configured so that it can be installed by removing it from the hole 69 and inserting the faucet inner insertion part 20 into the opened hole 69, it is a faucet that is generally widely used in homes and the like. It is not necessary to modify the structure of 11, and it can be easily installed in a wide range of general faucets. Therefore, since it is possible to use the structure of water faucets that have been widely used in the past as is, it is possible to automatically open and close the water faucets at low cost. In this embodiment, an example has been described in which both the automatic valve opening/closing means 21 and the manual valve opening/closing means 75 are installed as the valve opening/closing means, but the invention is not limited to the above embodiment. The automatic valve opening/closing means 21 may not be provided with the means 75, and the technical configuration of the automatic valve opening/closing means 21 is not limited to the above embodiment. An example has been described in which the configuration is such that the amount of water discharged from the tap 11 of the water supply lO can be adjusted. You can. [Effects of the Invention] Since the faucet opening/closing device according to the present invention has one or more configurations, it can be easily installed without changing the structure of faucets that have conventionally been widely used in homes. It can be quickly attached to the faucet, and it is simple and inexpensive! The closing operation can be automated, and the user can open and close the faucet without touching the faucet directly.
