Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

the first embodiment,

As shown in fig. 1 to 9, the intelligent faucet solves the problems that the intelligent faucet in the prior art only has long water outlet induction or induced water outlet induction, cannot be switched according to actual needs, and is single in control mode. The invention provides an intelligent faucet.

The intelligent faucet comprises a main body component 1, a beam component 3 which is rotatably arranged on the main body component 1, a water outlet component 2 which is provided with a fixed end 6 and a movable end 10 which are arranged on the beam component 3, a first induction component 11 which is arranged at the position of the beam component 3 close to the fixed end 6 and is used for detecting an object above the beam component 3, a second induction component 12 which is arranged at the position of the beam component 3 close to the movable end 10 and is at least used for detecting the object below the beam component 3, a valve component 4 and a control component 5. The movable end 10 is movably disposed on the beam assembly 3. The fixed end 6 is provided with a water inlet 21, and the movable end 10 is provided with a water outlet 28.

In the embodiment, the beam assembly 3 has a connecting hole 23 at one end for communicating with the main assembly 1, and a receiving hole at the other end for receiving the movable end 10. The attachment hole 23 is rotatably provided in the main body unit 1. The water outlet assembly 2 is a tubular geometry at least partly made of a flexible material or a flexible material. One end of which is provided with a water inlet 21 and the other end is provided with a water outlet 28. The end of the water outlet component 2 provided with the water inlet 21 is a fixed end 6, and the end provided with the water outlet 28 is a movable end 10. The fixing end 6 is disposed in the connecting hole 23 so that the water inlet 21 is communicated with the main body assembly 1. The movable end 10 is movably embedded in the receiving hole, so that a closed loop is formed between the water outlet assembly 2 and the beam assembly 3. The position made of the flexible material or the flexible material is deformed so that the movable end 10 can move away from the receiving hole.

Preferably, the fixing end 6 is arranged in the connection hole 23 so as not to be rotatable. I.e. the water outlet assembly 2 cannot rotate relative to the cross beam assembly 3. And the beam component 3 can drive the water outlet component 2 to rotate relative to the main component 1 when rotating. That is, when the movable end 10 is fitted in the receiving hole, the position of the water outlet 28 is adjusted by rotating the cross member assembly 3. When the movable end 10 is not inserted into the receiving hole, the position of the water outlet 28 is adjusted by twisting the water outlet assembly 2.

It can be understood that the sensing direction of the first sensing assembly 11 can be upward or obliquely upward. When upwards setting, first response subassembly 11 configuration can set up with the upper surface parallel and level of beam assembly 3 at the response window of beam assembly 3, the tap of being convenient for washs. When the beam assembly is arranged obliquely upward, an inclined surface needs to be arranged on the beam assembly 3. The sensing window of the first sensing assembly 11 is arranged on the inclined plane, so that the sensing range of the first sensing assembly 11 covers the space between the beam assembly 3 and the water outlet assembly 2 as much as possible, and the recognition rate is improved. When the user uses the device, the user does not need to carefully observe the position of the first sensing assembly 11, and only needs to naturally extend the hand to be sensed.

Specifically, the valve assembly 4 is connected to the water outlet 28 and an external water source for controlling whether the water outlet 28 is discharged. The control assembly 5 is electrically connected to the valve assembly 4, the first sensing assembly 11 and the second sensing assembly 12, and is used for controlling the valve assembly 4 to open or close according to an electric signal of the first sensing assembly 11 so as to enable the water faucet to grow water; and controlling the valve assembly 4 to open according to the electric signal of the second sensing assembly 12 so that the faucet senses the water.

The water outlet mode is as follows: the sensing turns on the faucet once and turns off the faucet again. The induction water outlet mode is as follows: and setting a condition for opening the faucet, opening when the condition is met, and closing when the condition is not met. For example: turning on the faucet when an object is sensed at a predetermined position, and turning off the faucet when no object is sensed; or, the water tap is turned on when the tap handle or the water outlet is detected to be away from the preset position, and the water tap is turned off when the tap handle or the water outlet is detected to be in the preset position.

In the embodiment of the invention, the first sensing assembly 11 senses the object above the beam assembly 3, and the second sensing assembly 12 senses the object below the beam assembly 3, so that the induction faucet has two modes of sensing water outlet and water outlet. In addition, the triggering areas of the first sensing assembly 11 and the second sensing assembly 12 are separated through the cross beam assembly 3, so that the touch screen cannot be touched by mistake in use, and the touch screen has good practical significance.

As shown in fig. 2, on the basis of the above embodiment, in an alternative embodiment of the present invention, the main body assembly 1 includes a housing for disposing the beam assembly 3, and a valve core and a handle disposed on the housing.

In this embodiment, the valve core is a multifunctional valve for switching on and off water flow and adjusting water flow temperature. The multifunctional valve is used for mixing cold water and hot water and then outputting the mixed water from a mixed water outlet, and switching on and off water flow. The valve core is provided with a cold water inlet, a hot water inlet and a mixed water outlet. The handle is arranged on the valve core and used for controlling the valve core.

Specifically, the body assembly further includes a cold water inlet pipe 18 to connect the cold water inlet and an external cold water source, a hot water inlet pipe 17 to connect the hot water inlet and an external hot water source, a mixed water outlet pipe 16 to connect the mixed water outlet and the first solenoid valve 14, and a connection pipe 15 to connect the solenoid valve and the water outlet 28. The first solenoid valve 14 is connected to the mixed water outlet and the water outlet 28 through the mixed water outlet pipe 16 and the connection pipe 15.

In other embodiments, the valve core may be a single function temperature regulating valve that can only be used to regulate temperature. Or the valve core can be an on-off valve which can only be used for on-off water, and only one water inlet pipe is needed at the moment to be used for communicating the on-off valve with an external water source.

As shown in fig. 1 to 5, in an alternative embodiment of the present invention, the beam assembly 3 includes a substantially elongated upper cover 9 and a lower cover 13 disposed on the upper cover 9. The upper cover 9 is provided with a connecting hole 23 and a receiving hole. The upper cover 9 is provided with a connecting shaft 22 extending along the axial direction of the connecting hole 23, and the connecting shaft 22 is sleeved with a sealing ring and embedded into the main body component 1, so that the upper cover 9 can be rotatably arranged on the main body component. And, the connection hole 23 is made to communicate to the inside of the body assembly. The connecting hole 23 and the receiving hole are both through holes 8.

The upper cover 9 is provided with a receiving groove and a through hole 8 opening downward between the connection hole 23 and the receiving hole. The through hole 8 substantially divides the receiving groove into a second sensing volume adjacent to the receiving hole and a first sensing volume adjacent to the connecting hole 23. The lower cover 13 is disposed on the upper cover 9 for covering the opening of the receiving groove. The second sensing cavity is communicated with the first sensing cavity, and the first sensing cavity is communicated with the connecting hole 23.

Through setting the holding tank to the structure that the opening is decurrent, can guarantee that the upper surface of upper cover 9 and the side of all directions all do not have broken face, the integration effect is stronger for upper cover 9's outward appearance is more pleasing to the eye.

In this embodiment, the faucet further includes a spray head assembly disposed at the water outlet 28, and a hose for connecting the spray head assembly and the connection pipe 15. The hose is embedded in the water outlet assembly 2 and penetrates the water inlet 21 and the water outlet 28. The use of a hose to connect the spray head assembly to the connection pipe 15 prevents water from directly contacting the water outlet assembly. Slowing down the aging effect of the water outlet assembly and ensuring the cleanness of water quality, thereby having good practical significance.

As shown in fig. 6, on the basis of the above embodiment, in an alternative embodiment of the present invention, a limiting structure is disposed between the beam assembly 3 and the main body assembly 1, so that the beam assembly 3 can rotate within a predetermined angle. Specifically, in the present embodiment, the limiting structure is a first protrusion 25 extending outward from the connecting shaft 22 and a second protrusion 26 extending from the main body assembly toward the connecting shaft 22. When the beam assembly 3 rotates to a certain angle, the first protrusion 25 abuts against the second protrusion 26, so as to restrict the beam assembly 3 from further rotating, and the beam assembly 3 cannot rotate three hundred sixty degrees relative to the main body assembly 1.

By arranging the limiting structure between the beam assembly 3 and the main body assembly 1, the connecting pipe 15 and the hose inside the main body assembly 1, and the signal wires for connecting the control assembly 5, the first sensing device 20 and the second sensing device 24 are ensured not to be excessively twisted. Thereby guaranteeing the service life of the water tap.

In another embodiment, the body assembly may not have the second protrusion 26, but a groove is provided, so that the first protrusion 25 can only rotate in the groove, and the rotation angle of the beam assembly 3 relative to the body assembly 1 can also be limited.

As shown in fig. 2 to 4, in an alternative embodiment of the present invention, the beam assembly 3 is substantially in a long strip shape, and a through hole 8 is formed in the middle. The side of the through hole 8 near the connection hole 23 is provided with an inclined side wall 7 inclined toward the inner area. The cross beam assembly 3 is configured with a first sensing volume in communication with the inclined side wall 7. The first sensing assembly 11 includes a first sensing device 20 disposed in the first sensing chamber for detecting whether an object is present in an inner region of the closed loop. Optionally, the first sensing device 20 is a TOF sensor or an infrared sensor, which is disposed obliquely upward to detect the object along the orientation of the inclined sidewall 7.

As shown in fig. 2, 3 and 4, the first sensing device 20 includes a housing, and an infrared sensor disposed in the housing. The housing has a side face adapted to the inclined side wall 7, on which side face the infrared sensor is arranged. The side and the inclined side wall 7 combine to form a plane when the housing is inserted into the first sensing chamber. While the infrared sensor is capable of detecting an object in a direction perpendicular to the inclined side. Since the infrared sensor is disposed at a position close to the connection hole 23 and the detection direction is set obliquely upward. Thus, a substantial portion of the space within the closed loop area can be detected. The user can detect the hand by simply inserting the hand into the closed loop without moving the handle to a more specific position. And because the sensing area is a closed loop area, the sensing area is not easy to be touched by mistake.

In other embodiments, a protrusion may be provided on the upper lid 9 to form the inclined side wall 7 and the first sensing volume.

As shown in fig. 5, in other embodiments, the first sensing assembly 11 may further include a second sensing device 24 disposed in the first sensing chamber, or only the second sensing device 24. The second sensing device 24 is a voice recognition device, and is disposed on the lower wall of the first sensing chamber for detecting sound.

Specifically, the voice recognition device is a microphone electrically connected to the control unit 5. The microphone is used for collecting sound information, and the control component 5 is used for identifying whether the faucet is opened or not according to the collected sound information. The voice is collected by the microphone, and the required information is identified from the voice, which is the prior art, and the invention is not described herein again. The water faucet is controlled according to the information, so that the user can control the water faucet to grow water through sound. The condition that the cross beam assembly 3 is polluted due to the falling of dirty objects when hands are not clean and the water outlet mode is opened by placing the hands above the cross beam assembly 3 is avoided.

In an alternative embodiment of the present invention, as shown in fig. 7, 8 and 9, based on the above-mentioned embodiment, the cross beam assembly 3 has a second sensing cavity adjacent to the receiving hole. The second sensing assembly 12 includes a third sensing device 27 and a fourth sensing device disposed in the second sensing volume. Specifically, the third sensing device 27 is a TOF sensor or an infrared sensor, which is disposed downward to detect the object below the receiving hole. The fourth sensing device is disposed toward the receiving hole for detecting whether the movable end 10 is located in the receiving hole.

In this embodiment, the second sensing cavity is adjacent to the receiving hole, and the third sensing device 27 is an infrared sensor. The infrared sensor is arranged downwards, and when the hand is positioned below the accommodating hole, the third sensing device 27 is triggered, so that the faucet enters a water sensing mode.

As shown in fig. 8, on the basis of the above embodiment, in an alternative embodiment of the present invention, the fourth sensing device is a magnetic control device 30. The second inductive element 12 further includes a magnetic element 29 disposed at the movable end 10. When the movable end 10 is fitted in the receiving hole, it can be detected by the magnetron device 30.

Specifically, the magnetron device 30 is a hall sensor element, which is capable of detecting a magnetic field. A magnetic member 29 is provided on a portion where the movable end 10 is inserted into the receiving hole. So that the magnetic field in the second sensing chamber is changed when the movable end 10 is inserted into and separated from the receiving hole. A hall sensing element is arranged in the second sensing cavity, so that whether the movable end 10 is embedded in the accommodating hole can be detected. The control assembly 5 is electrically connected to the hall sensor, and when sensing that the movable end 10 leaves the receiving hole, opens the solenoid valve to allow the faucet to sense water.

The magnetic control device 30 is used for detecting whether the movable end 10 is positioned or not, and holes do not need to be drilled on the beam assembly 3. Can guarantee beam assembly 3's an organic whole nature, not only pleasing to the eye, can effectually prevent moreover that inside from intaking, have fine practical meaning.

In this embodiment, the magnetic member 29 is annular, and the beam assembly 3 is provided with a metal member located in the accommodating hole, so that when the movable end 10 is embedded in the accommodating hole, a certain adsorption force is provided, which not only ensures that the movable end 10 is matched in place, but also ensures that the movable end 10 cannot be separated from the accommodating hole at will.

As shown in fig. 9, on the basis of the above embodiment, in an alternative embodiment of the present invention, the fourth sensing device is a position switch 32. The position switch 32 protrudes into the receiving hole to be triggered when the movable end 10 is inserted into the receiving hole. The position switch 32 is disposed in the second sensing cavity and has a driving rod extending toward the receiving hole. When the movable end 10 is inserted into the receiving hole, the actuating lever is pressed, thereby actuating the position switch 32. The position switch 32 can also detect whether the movable end 10 is in the receiving hole.

Preferably, the second sensing assembly 12 further comprises an oscillating member 31 hinged to the second sensing volume. In a natural state, the swing member 31 has one side protruding into the receiving hole and the other side abutting against the driving rod. When the movable end 10 is inserted into the receiving hole, the swinging member 31 is swung, thereby driving the driving rod to trigger the position switch 32. Whether the movable end 10 is accommodated in the accommodating hole is detected through the position switch 32, and the mechanical structure is adopted, so that the cost is lower.

As shown in fig. 10 and 12, on the basis of the above embodiments, in an alternative embodiment of the present invention, the control assembly 5 is electrically connected to the first sensing assembly 11, the third sensing device 27 and the fourth sensing device, respectively. In particular, the first inductive component 11, the third inductive means 27 and the fourth inductive means are electrically connected directly to the control component 5. The control unit 5 can directly receive the signals from the respective sensing devices and then control the solenoid valves. Thus, the sub-connection enables the faucet to react faster.

In other implementations, as shown in fig. 11 and 13, the control assembly 5, the first sensing assembly 11, the third sensing device 27 and the fourth sensing device are electrically connected in sequence. Specifically, the fourth sensing device is electrically connected to the third sensing device 27, the third sensing device 27 is electrically connected to the first sensing element 11, and the first sensing element 11 is electrically connected to the control element 5. The electric connection structure can effectively reduce the number of internal lines of the water faucet on the premise of transmitting signals of all the sensors to the control assembly 5. Thereby saving the space of little soil and little gold in the water faucet.

Example II,

On the basis of the first embodiment, the invention further provides a multi-sensing intelligent faucet. The principle of implementation and the technical effects produced are the same as in the first embodiment. In the following, for a brief description, the present embodiment does not refer to the corresponding contents in the first embodiment.

It is understood that the first embodiment is a more specific hardware structure of the second embodiment. Based on the technical solution disclosed in the second embodiment, those skilled in the art can easily think that the technical solution of the second embodiment is applied to (or modified into) a hardware structure different from the first embodiment, so as to solve the problem of confusion of the control logic of the existing induction faucet.

As shown in fig. 1, 2, 10 and 11, the multi-sensing intelligent faucet includes a faucet body, a first solenoid valve 14, a first sensing element 11 disposed on the faucet body for detecting a first action of a user, a second sensing element 12 disposed on the faucet body for detecting a second action of the user, and a control element 5. The first electromagnetic valve is connected with the faucet body and an external water source and used for controlling whether water is discharged from the water outlet of the faucet or not.

Specifically, the faucet body can be a main body assembly 1, a cross beam assembly 3 and a water outlet assembly 2 in the first embodiment. Other existing faucet structures are also possible, and the embodiment of the present invention is not limited in this respect. In the present embodiment, the valve assembly 4 is a single solenoid valve, i.e., the first solenoid valve 14.

The specific content of the first action depends on the specific hardware structure of the first sensing element 11. For example: when the first sensing assembly is an infrared sensor, the first action is to use an object to shield the infrared sensor; when the first sensing assembly is a voice recognition device, the first action is to make a preset sound. It is understood that the specific content of the second action is also dependent on the specific hardware structure of the second sensing assembly. For example: when the second sensing assembly is an infrared sensor, the second action is to use an object to shield the infrared sensor; when the second sensing piece is a magnetic control device or a position switch, the second action is used for enabling the water outlet to leave the preset position.

The control assembly 5 is electrically connected to the first solenoid valve 14, the first sensing assembly 11, and the second sensing assembly 12. The control component 5 can control the first electromagnetic valve 14 to open according to the electric signal of the second sensing component 12 so as to enable the faucet body to sense water, and control the first electromagnetic valve 14 to open or close according to the electric signal of the first sensing component 11 so as to enable the faucet body to discharge water for a long time. The control assembly 5 can close the second sensing assembly 12 or shorten the sensing distance of the second sensing assembly 12 when the faucet body is growing water.

In this embodiment, the first sensing component 11 will send out an electrical signal when detecting a first action of the user, and the second sensing component 12 will also send out an electrical signal when detecting a second action of the user. The control assembly 5 simultaneously controls the first solenoid valve 14 according to the electric signals of the first and second sensing assemblies 11 and 12.

Specifically, the control component 5 controls the first electromagnetic valve 14 to open or close according to the electrical signal of the first sensing component 11 so as to enable the faucet to grow water, and controls the first electromagnetic valve 14 to open according to the electrical signal of the second sensing component 12 so as to enable the faucet to sense water. When the faucet is in long water outlet, the second sensing assembly 12 used for sensing water outlet is closed or the sensing distance of the second sensing assembly 12 is shortened, so that the situation that the electromagnetic valve is closed and water is cut off due to the fact that the second sensing assembly 12 is touched by mistake in the long water outlet process can be avoided.

In other implementations, the control assembly 5 is configured to stop the sensing of the second sensing assembly 12 when the solenoid valve is opened by the first sensing assembly 11. When the solenoid valve is opened by the second sensing member 12, the sensing of the first sensing member 11 is stopped. When the solenoid valve is closed, the sensing of the first sensing assembly 11 and the second sensing assembly 12 is restored.

For example, when the tap is turned on by the first sensing assembly 11, it may be washing fruits or bowls and chopsticks. While during cleaning there are situations where the hands are leaving under the water outlet 28. In this case, the prior art would turn off the faucet, thereby causing the user to repeatedly turn on the faucet through the first sensing assembly 11, which seriously affects the user experience. And this embodiment, when opening the solenoid valve through a response subassembly, stops the response of another response subassembly, the emergence of avoiding this kind of condition that can be fine has promoted user experience greatly, has fine practical meaning.

On the basis of the above embodiments, in an alternative embodiment of the present invention, the first sensing assembly 11 includes the first sensing device 20 and/or the second sensing device 24 configured at a first predetermined position of the faucet body. The first sensing device 20 is used to detect whether there is an object within a first predetermined range. The second sensing device 24 is used for detecting sound. Optionally, the first sensing device 20 is a TOF sensor or an infrared sensor. The second sensing device 24 is a voice recognition device.

In the present embodiment, the first predetermined position is a position where the cross member assembly 3 is close to the attachment hole 23. In other embodiments, the first predetermined position may be disposed on the side of the main body assembly 1 or the upper surface of the water outlet assembly 2. In other embodiments, the faucet body is a conventional elbow faucet, and the first predetermined location may be located on an upper surface of the elbow, or the elbow may be connected to a side of the wash basin. The present invention is not limited to the specific location of the first predetermined location and the specific configuration of the faucet body.

On the basis of the above embodiments, in an alternative embodiment of the present invention, the second sensing assembly 12 includes a third sensing device 27 and/or a fourth sensing device disposed at a second predetermined position of the faucet body. The third sensing device 27 is used for detecting whether an object is in the second predetermined range. The fourth sensing device is used for detecting whether the water outlet 28 is at a preset position. Optionally, the third sensing means 27 is a TOF sensor or an infrared sensor. The fourth sensing device is a magnetic control device 30 or a position switch 32.

In the present embodiment, the second predetermined position is a position where the beam assembly 3 is close to the receiving hole. In other embodiments, the second predetermined position may also be disposed at the water outlet 28. In other embodiments, where the faucet body is a conventional elbow faucet, the second predetermined location may be located at the end of the elbow so as to detect objects in front of the nozzle 28. The invention is not limited to the specific location of the second predetermined location and the specific configuration of the faucet body.

On the basis of the above embodiment, in an alternative embodiment of the present invention, when the second sensing assembly 12 includes the third sensing device 27, the control assembly 5 can close the second sensing assembly 12 or shorten the sensing distance of the second sensing assembly 12 when the faucet body is growing water, specifically: the control assembly 5 is capable of turning off the third sensing means 27 or shortening the sensing distance of the third sensing means 27 when the faucet body is out of water.

Specifically, the third sensing device 27 is used to detect the object in front of the nozzle, which is most likely to be touched by mistake when the water is running out. Therefore, the third sensing device 27 is turned off or the sensing distance of the third sensing device 27 is shortened when the water is grown. The third sensing device 27 can be effectively prevented from being touched by mistake. Has practical significance.

On the basis of the above embodiment, in an alternative embodiment of the present invention, when the second sensing assembly 12 includes the third sensing device 27 and the fourth sensing device: the control assembly 5 is also able to close the third sensing device 27 or shorten the sensing distance of the third sensing device 27 when the solenoid valve is opened according to the electric signal of the fourth sensing device.

Specifically, the fourth sensing device is used to detect whether the water outlet is at a preset position, and the detection object is the water outlet 28 (i.e. the end of the water outlet assembly 2). Therefore, the water can not be touched by mistake in the process of water growing, only the third sensing device 27 is turned off when the water grows, and the fourth sensing device works as usual. When the fourth sensing device triggers the sensing of water, the third sensing device 27 is turned off or the sensing distance of the third sensing device 27 is shortened. It is also possible to prevent water cut-off due to the third sensing device 27 being touched by mistake.

On the basis of the above embodiment, in an optional embodiment of the present invention, the control component 5 can also control the electromagnetic valve to close when the faucet body is growing water and returns to the predetermined position after the fourth sensing device detects that the water outlet 28 leaves the predetermined position. Specifically, when the fourth sensing assembly triggers sensing water out, it means that the water outlet 28 is away from the predetermined position. This is often the case because of deliberate de-triggering by humans. Therefore, it is not always a false touch in this case. When the water outlet is detected to return to the preset position, the first electromagnetic valve is controlled, so that the water outlet can be closer to the actual situation, and the water outlet is more humanized.

In other embodiments, the control assembly may be configured to control the solenoid valve to remain open when the faucet body is extended and returns to a predetermined position after the fourth sensing device detects that the water outlet 28 leaves the predetermined position.

The control assembly 5 comprises a memory and a controller configured to execute a computer program in the memory to implement the steps of:

and S1, monitoring the first sensing assembly 11 and the third sensing device 27.

S2, when the electric signal of the first sensing assembly 11 is monitored, the first solenoid valve 14 is controlled to open, and the monitoring of the third sensing device 27 is stopped or the sensing distance of the third sensing device 27 is shortened.

S3, when the electric signal of the first sensing assembly 11 is monitored again, the first solenoid valve 14 is controlled to close, and the monitoring of the third sensing device 27 is resumed or the sensing distance of the third sensing device 27 is resumed.

On the basis of the above embodiment, an optional embodiment of the present invention further includes at least the following steps:

and S4, monitoring the fourth sensing device and judging whether the movable end 10 leaves the accommodating hole.

And S5, when the movable end 10 is judged to leave the accommodating hole, controlling the first electromagnetic valve 14 to be opened, and stopping monitoring the third sensing device 27 or shortening the sensing distance of the third sensing device 27.

And S6, when the movable end 10 is embedded in the accommodating hole, controlling the first electromagnetic valve 14 to be closed, and restoring to monitor the third sensing device 27 or restoring the sensing distance of the third sensing device 27.

In the embodiment of the present invention, the third sensing device 27 is turned off or the sensing distance of the third sensing device 27 is shortened under the condition that the first sensing assembly 11 and the fourth sensing device trigger water, so that the condition of mistaken touch is avoided more effectively.

and S7, when the opening time of the first electromagnetic valve 14 is judged to reach the preset time length, controlling the first electromagnetic valve 14 to be closed, and resuming monitoring of the third sensing device 27 or resuming sensing distance of the third sensing device 27. Wherein, the preset time period can be 3 minutes or 4 minutes, or any other time period.

Specifically, when the faucet is turned on for three minutes, the faucet is directly turned off, so that the faucet is prevented from being discharged due to the fact that the faucet touches the first sensing assembly 11 by mistake or the water outlet assembly 2 falls off the beam assembly 3 accidentally. When the opening time of the faucet reaches the preset time length, the faucet is closed, and waste of water resources can be effectively reduced.

Example III,

On the basis of the first embodiment, the invention further provides a multi-sensing faucet. The principle of implementation and the technical effects produced are the same as in the first embodiment. In the following, for a brief description, the present embodiment does not refer to the corresponding contents in the first embodiment.

It is to be understood that the first embodiment is a more specific hardware structure of the third embodiment. Based on the technical solutions disclosed in the third embodiment, those skilled in the art can easily think that the technical solutions of the third embodiment are applied to (or modified into) a hardware structure different from the first embodiment, so as to solve the problem of single control mode of the existing faucet.

As shown in fig. 3, 12 and 13, the multi-sensing faucet includes a faucet body, a first solenoid valve 14 and a second solenoid valve 19 disposed in parallel, a first sensing assembly 11 disposed in the faucet body for detecting a first action of a user, a second sensing assembly 12 disposed in the faucet body for detecting a second action of the user, and a control assembly 5.

Specifically, the faucet body can be a main body assembly 1, a cross beam assembly 3 and a water outlet assembly 2 in the first embodiment. Other existing faucet structures are also possible, and the embodiment of the present invention is not limited in this respect.

The first electromagnetic valve 14 and the second electromagnetic valve 19 are both connected to the faucet body and an external water source to control whether water is discharged from the water outlet of the faucet. The control assembly 5 is electrically connected to the first solenoid valve 14, the second solenoid valve 19, the first sensing assembly 11, and the second sensing assembly 12. The control component 5 can control the second electromagnetic valve 19 to open according to the electric signal of the second sensing component 12 so as to enable the faucet body to sense water, and control the first electromagnetic valve 14 to open or close according to the electric signal of the first sensing component 11 so as to enable the faucet body to discharge water for a long time.

In the present embodiment, the valve assembly 4 includes a first solenoid valve 14 and a second solenoid valve 19 connected in parallel. The control assembly 5 is electrically connected to the first solenoid valve 14 and the second solenoid valve 19, respectively. The control component 5 controls the first electromagnetic valve 14 according to the electric signal of the first sensing component 11 to enable the faucet to grow out, and controls the second electromagnetic valve 19 according to the electric signal of the second sensing component 12 to enable the faucet to sense the water out. The water tap is ensured not to be accidentally cut off due to the electric signal of the second sensing assembly 12 when the water tap is in long-time water outlet, and the water tap has good practical significance.

On the basis of the above embodiments, in an alternative embodiment of the present invention, the control assembly 5 can turn off the second sensing assembly 12 or shorten the sensing distance of the second sensing assembly 12 when the faucet body is growing water. Particularly, whether the second sensing assembly is triggered or not does not affect the water outlet effect even when water is grown. However, when water is discharged, the second sensing assembly 12 is turned off or the sensing distance of the second sensing assembly 12 is shortened, so that the power consumption of the multi-sensing faucet can be greatly reduced, and energy is saved. Has good practical significance.

In other implementations, the control assembly 5 is configured to stop the sensing of the second sensing assembly 12 when the solenoid valve is opened by the first sensing assembly 11. When the solenoid valve is opened by the second sensing member 12, the sensing of the first sensing member 11 is stopped. When the solenoid valve is closed, the sensing of the first sensing assembly 11 and the second sensing assembly 12 is restored. Specifically, close first response subassembly 11 when tap response goes out water, close second response subassembly 12 when tap length goes out water, under the prerequisite of guaranteeing tap normal use, great saving tap required electric energy.

In particular, the third sensing means 27 is used to detect objects in front of the nozzle, which can easily be triggered when water is coming out. Therefore, the third sensing device 27 is turned off or the sensing distance of the third sensing device 27 is shortened when the water is grown. First solenoid valve and second solenoid valve open simultaneously when can effectively avoiding long water to practice thrift the electric energy, have fine practical meaning.

On the basis of the above embodiment, in an alternative embodiment of the present invention, when the second sensing assembly 12 includes the third sensing device 27 and the fourth sensing device, the control assembly 5 can also close the third sensing device 27 or shorten the sensing distance of the third sensing device 27 when the second solenoid valve 19 is opened according to the electric signal of the fourth sensing device.

Specifically, the fourth sensing device is used to detect whether the water outlet is at a preset position, and the detection object is the water outlet 28 (i.e. the end of the water outlet assembly 2). Therefore, the water can not be touched by mistake in the process of water growing, only the third sensing device 27 is turned off when the water grows, and the fourth sensing device works as usual. When the fourth sensing device triggers the sensing of water, the third sensing device 27 is turned off or the sensing distance of the third sensing device 27 is shortened. Not only can the electric energy be saved, but also the water cut-off caused by the false touch of the third sensing device 27 can be prevented.

On the basis of the above embodiment, in an alternative embodiment of the present invention, the control assembly 5 can also control the first solenoid valve 14 and the second solenoid valve 19 to be closed when the faucet body is growing water and the fourth sensing device detects that the water outlet 28 leaves the predetermined position and then returns to the predetermined position. Specifically, when the fourth sensing assembly triggers sensing water out, it means that the water outlet 28 is away from the predetermined position. This is often the case because of deliberate de-triggering by humans. Therefore, it is not always a false touch in this case. When the water outlet is detected to return to the preset position, the first electromagnetic valve is controlled, so that the water outlet can be closer to the actual situation, and the water outlet is more humanized.

In other embodiments, the control assembly 5 may be configured to control the first solenoid valve 14 and the second solenoid valve 19 to maintain the current state when the faucet body is growing water and the fourth sensing device detects that the water outlet 28 leaves the predetermined position and then returns to the predetermined position.

On the basis of the above embodiment, in an alternative embodiment of the present invention, when the second sensing assembly 12 includes the third sensing device 27 and the fourth sensing device, the method further includes the following steps:

And S5, when the movable end 10 is judged to leave the accommodating hole, controlling the second electromagnetic valve 19 to be opened, and stopping monitoring the third sensing device 27 or shortening the sensing distance of the third sensing device 27.

And S6, when the movable end 10 is embedded in the accommodating hole, controlling the second electromagnetic valve 19 to be closed, and restoring to monitor the third sensing device 27 or restoring the sensing distance of the third sensing device 27.

In the embodiment of the present invention, when the first sensing assembly 11 and the fourth sensing device trigger the water to flow out, the third sensing device 27 is turned off or the sensing distance of the third sensing device 27 is shortened. The power consumption of the faucet can be saved, and the faucet has good practical significance.

and S7, when the opening time of the first electromagnetic valve 14 or the second electromagnetic valve 19 is judged to reach the preset time, closing the first electromagnetic valve 14 and the second electromagnetic valve 19, and resuming the monitoring of the third sensing device 27 or resuming the sensing distance of the third sensing device 27. Wherein, the preset time period can be 3 minutes or 4 minutes, or any other time period.
