The present invention relates to sanitary product technology, and in particular to a multi-mode manipulated water outlet device.
Existing faucets can be divided into ordinary mechanically-manipulated faucets, inductively-manipulated faucets and others according to their manipulation modes. In a case where people want to manipulate the mechanically-manipulated faucet through induction to conveniently and quickly open or close the flow path, or the inductively-manipulated faucet fails to work when powered off, the faucet cannot be used. It is, therefore, highly desirable to provide a faucet with an integration of the two manipulation modes to meet user requirements.
In order to solve the above-mentioned problems, the present invention provides a multi-mode manipulated water outlet device.

As shown in
The first temperature control valve group 12 includes the first valve core 121 fixedly disposed on the main body 11 and the first switch 122 sleeved on the first valve core 121 to control the first valve core 121. In the present embodiment, the first valve core 121 is a mixing valve, and the first switch 122 is inserted into the mixing valve. The mixing valve is opened or closed by lifting up or pressing down the handle 1221 of the first switch 122, and the hot-water and cold-water output ratio of the mixing valve is adjusted by rotating the first switch 122 to the left and right. The first water inlet unit includes three hoses. One end of each of two hoses communicates with the first valve core 121, one end of the remaining hose is directly in communication with the first water outlet unit 13, and the other end of each of the three hoses has an interface. The three interfaces are the hot-water inlet 15, the cold-water inlet 16 and the mixed-water inlet 17, respectively. The first water outlet unit 13 is movably and fixedly disposed on the main body 11 or integrally disposed with the main body 11, and communicates with the first valve core 121. The water flows into the first valve core 121 from the hot-water inlet 15, the cold-water inlet 16 and the mixed-water inlet 17, respectively, and then flows out from the first water outlet unit 13.
The second temperature control valve group 23 includes the valve seat 231 fixedly disposed in the cavity, the second valve core 232 disposed in the valve seat 231, and the second switch 233 sleeved on the second valve core 232 to control the second valve core 232. The valve seat 231 has a valve cavity for receiving the second valve core 232, and the hot-water passing port 235, the cold-water passing port 236 and the mixed-water passing port 237 communicating with the valve cavity. The second valve core 232 adopts a mixing valve or a thermostatic valve. In the present embodiment, the second valve core 232 adopts a thermostatic valve, and the second switch 233 adopts a knob and is inserted into a connecting rod of the thermostatic valve. The outlet water temperature of the thermostatic valve can be set by rotating the knob. The outlet water temperature is set according to the user's requirements when leaving the factory, and can be adjusted as needed after manually opening the upper cover 22. After the outlet water temperature has been adjusted, the upper cover 22 is closed and fastened. The second water outlet unit includes the first water outlet hole 252, the cold-water outlet hole 262 and the mixed-water outlet hole 272. The second water inlet unit includes the hot-water inlet hole 251 and the cold-water inlet hole 261. The hot-water inlet hole 251 and the first water outlet hole 252 are disposed in the hot-water pipe 25. The cold-water inlet hole 261 and the cold-water outlet hole 262 are disposed in the cold-water pipe 26. The mixed-water outlet hole 272 is disposed in the mixed-water pipe 27. The hot-water pipe 25 is further provided with the hot-water passing hole 253. The cold-water pipe 26 is further provided with the cold-water passing hole 263. The mixed-water pipe 27 is further provided with the mixed-water passing hole 271. The hot-water passing port 235 communicates with the hot-water passing hole 253. The cold-water passing port 236 communicates with the cold-water passing hole 263. The mixed-water passing port 237 communicates with the mixed-water passing hole 271. The first water outlet hole 252 communicates with the hot-water inlet 15. The cold-water outlet hole 262 communicates with the cold-water inlet 16. The mixed-water outlet hole 272 communicates with the mixed-water inlet 17. The mixed-water inlet 17 communicates with the first water outlet unit 13. The water flows in from the hot-water inlet hole 251 and the cold-water inlet hole 261, and then flows to the hot-water inlet 15 and the cold-water inlet 16 from the first water outlet hole 252 and the cold-water outlet hole 262. Alternatively, the water flows in from the hot-water inlet hole 251 and the cold-water inlet hole 261, then flows to the hot-water passing port 235 and the cold-water passing port 236 from the hot-water passing hole 253 and the cold-water passing hole 263, and then flows to the mixed-water passing port 237 via the second valve core 232 to flow to the mixed-water passing hole 271, so as to flow to the mixed-water inlet 17 from the mixed-water outlet hole 272.
Further, the solenoid valve 24 and the chip set 28 are fixedly provided in the cavity. The solenoid valve 24 is connected to the flow path between the mixed-water passing hole 271 and the second valve core 232. The chip set 28 is electrically connected to the solenoid valve 24. The chip set 28 further includes the induction interface 282 and the power interface 281. The induction interface 282 is electrically connected to the second induction unit 14, and the power interface 281 is connected to an external power supply to enable the chip set 28 to work while supplying power to the second induction unit 14 and the solenoid valve 24 to enable them to work. In the present embodiment, the second induction unit 14 adopts an infrared induction structure, To open the flow path, the user only needs to put his/her hand in a position close to the infrared induction structure, so that the second induction unit 14 receives a flow path opening instruction to trigger the second induction unit 14 to control the chip set 28 to work, that is, transmit the instruction to the chip set 28 to enable the chip set 28 to control the solenoid valve 24 to be opened to open the flow path. After the water flows for a period of time, the solenoid valve 24 stops working to close the flow path, and the water passage work duration of the solenoid valve 24 can be preset according to the user's requirement. When the solenoid valve 24 starts to work, the water flows into the second valve core 232 respectively from the hot-water inlet hole 251 and the cold-water inlet hole 261 for mixing. The second valve core 232 can preset the water temperature according to the user's requirement. After being mixed in the second valve core 232, the water flows to the mixed-water passing hole 271 via the solenoid valve 24 to flow to the mixed-water passing port 237, and then flows to the mixed-water inlet 17 to enter the faucet body 1 and flows out from the first water outlet unit 13 for use. It is also feasible to directly put one hand proximate the infrared induction structure, so that the second induction unit 14 triggers a flow path closing instruction and transmits the water closing instruction to the chip set 28 to close the solenoid valve 24 to close the flow path.
In this way, the water outlet device can not only work in a mode in which the first switch 122 controls the first valve core 121 to mechanically open the flow path, but also can work in another mode in which the second induction unit 14 controls the solenoid valve 24 to enable the second valve core 232 to inductively open the flow path. However, a mistake in the mode in which the flow path is mechanically opened and closed may cause the second induction unit 14 to receive an induction signal to trigger the chip set 28 so as to make the solenoid valve 24 work to open the inductively opened and closed flow path. In this case, it is easy to cause a control disorder to increase the burden of the user during use, and also increase the work burden of the components to reduce the service life. In this regard, the main body 11 is further provided with the first induction unit 18 adjacent to the first temperature control valve group 12. The first induction unit 18 is triggered to turn off the trigger signal of the second induction unit 14, so as to ensure that the second induction unit 14 will not generate the induction signal to open the inductively opened and closed flow path. The first induction unit 18 adopts a contact switch, a Hall switch, a travel switch, or other known suitable switch. In the present embodiment, the first induction unit 18 adopts the contact switch, and the first induction unit 18 is disposed at one end of the first switch 122 adjacent to the gland 1211 of the first valve core 121. When the handle 1221 of the first switch 122 is lifted up, one end of the first switch 122 away from the handle 1221 is pressed down and contacts the first induction unit 18, and the first induction unit 18 senses that the first switch 122 turns on and off the work of the second induction unit 14. The first induction unit 18 can also be disposed inside the handle 1221 of the first switch 122. When a user operates the first switch 122, the user's hand contacts the first induction unit 18 to trigger the first induction unit 18 to turn off the work of the second induction unit 14. Any position where the first induction unit 18 can receive the work of the first switch 122 shall fall within the scope of protection of the position where the first induction unit 18 is disposed. The first induction unit 18 is electrically connected to the second induction unit 14.
The working principle of the present invention is briefly described as follows.
During normal use, the second switch 233 is turned on to open the second valve core 232, and the first induction unit 18 is triggered so that the second induction unit 14 is turned off and thus fails to transmit the signal to the chip set 28 for working. The hot water flows in from the hot-water inlet hole 251 and flow to the hot-water inlet 15 from the first water outlet hole 252. The cold water flows in from the cold-water inlet hole 261 and flows to the cold-water inlet 16 from the cold-water outlet hole 262. The hot water and the cold water are mixed through the first valve core 121, and then flow out from the first water outlet unit 13 for use. The second switch 233 is turned off to turn off the work of the second valve core 232 to close and disconnect the flow path.
When the second switch 233 does not open the second valve core 232 to work, the second induction unit 14 is used to receive the induction signal and transmit the signal to the chip set 28 so that the chip set 28 controls the solenoid valve 24 to be opened to open the flow path. In this way, the hot water flows in from the hot-water inlet hole 251, flows to the hot-water passing port 235 from the hot-water passing hole 253 to flow to the second valve core 232. The cold water flows in from the cold-water inlet hole 261 and flows to the cold-water passing port 236 from the cold-water passing hole 263 to flow to the second valve core 232. After being mixed through the second valve core 232, the hot water and the cold water flow to the solenoid valve 24 from the mixed-water passing hole 271 to flow to the mixed-water passing port 237, then flow to the mixed-water inlet 17 from the mixed-water outlet hole 272, and then flow to the first water outlet unit 13 for use. After working for a set time, the solenoid valve 24 is closed to close and disconnect the flow path. Alternatively, the second induction unit 14 receives a closing induction signal and transmits the signal to the chip set 28 to control the solenoid valve 24 to be closed to close and disconnect the flow path.
In the present invention, the second induction unit 14, the first temperature control valve group 12, the first water inlet unit and the first water outlet unit are disposed on the faucet body 1. The second temperature control valve group 23, the second water inlet unit and the second water outlet unit are disposed on the control box 2. The first water inlet unit communicates with the second water outlet unit. In this arrangement, by opening and closing the first temperature control valve group 12, the water flows into the second water outlet unit from the second water inlet unit, then flows to the first water inlet unit and then flows to the first water outlet unit via the first temperature control valve group 12 to provide a flow path manipulation mode. The second induction unit 14 is triggered to open and close the flow path, so that the water flows into the second water outlet unit from the second water inlet unit, then flows to the second temperature control valve group 23, and then flows to the first water outlet unit via the first water inlet unit to provide another flow path manipulation mode. In this way, two manipulated water outlet modes are provided in one water outlet device to not only facilitate quickly manipulating the mechanically-manipulated faucet, but also enable the inductively-manipulated faucet to continue to keep working when it is powered off, thereby providing various operating conveniences for users. The first induction unit 18 is configured to control the second induction unit 14 to be turned off to avoid the situation where the flow path is mistakenly opened by triggering the second induction unit 14 in a mechanical manipulation mode, while reducing the workload of components to prolong the service life
