Along with the continuous improvement of the quality of life of human beings, the functional requirement of people to the tap is also continuously improved, and induction tap is more and more popularized in people's life, especially in public place, and current induction tap performance is single, only utilizes the inductor control solenoid valve to impel the water route break-make. The induction tap is inconvenient to use because the water yield cannot be controlled in the using process and the induction tap needs to be used for a long time for water discharging.

There has also been a technology of combining an induction part with a mechanical faucet, and when people use a manual mode for a long time, an automatic mode is also normally operated at the same time, which also causes unnecessary interference to users. When the water yield is adjusted, the condition that the flow of the flow regulating valve is directly regulated to zero easily occurs, so that the faucet can not discharge water when the induction control is used again, the flow regulating valve is required to be operated again to discharge water, and the operation is inconvenient. And for the unknowns, the illusion that the sensing faucet has been damaged is given. Chinese patent CN101749456A discloses an integrated temperature-adjusting double-control induction faucet, which has two water paths for manual operation and induction control, but the structure of the faucet is very complicated.

For this reason, how to more intelligently control the electronic faucet using a simple structure is a problem that remains to be solved by those skilled in the art.

Detailed Description

The invention is described in further detail below with reference to the figures and specific examples.

As shown in fig. 1-3, a water outlet device includes: temperature regulation assembly 10, flow regulation assembly 20, water circuit electronic switch 30, electronic sensing assembly and control assembly 50. The control component 50 is in communication connection with the water channel electronic switch 30 and the electronic sensing component respectively, wherein the electronic sensing component is used for sensing a water using signal and sending the signal to the control component 50, the flow regulating component 20 is used for regulating the water outlet flow, the temperature regulating component 10 is used for regulating the water outlet temperature, the water channel electronic switch 30 is used for opening or closing a water channel under the control of the signal, and the control component 50 controls the water channel electronic switch 30 according to the signal sent by the electronic sensing component.

The flow regulating assembly 20 has a closed position with zero flow, a fully open position with maximum flow, and a first position therebetween (in which flow is greater than zero). The water outlet device also has a sensing assembly 60 for sensing the flow regulating position of the flow regulating assembly 20, the sensing assembly 60 being in communication with the control assembly 50. When the detecting component 60 detects that the flow rate adjusting component 20 reduces the flow rate to the first position (the flow rate adjusting component 20 changes from the position where the flow rate is larger than the flow rate corresponding to the first position), the detecting component 60 sends a signal to the control component 50, and the control component 50 closes the waterway electronic switch 30 according to the signal; when the detecting component 60 detects that the flow rate of the flow rate adjusting component 20 increases by a first position (the flow rate of the flow rate adjusting component 20 changes from the first position to a position where the flow rate is greater than the flow rate corresponding to the first position), the detecting component 60 sends a signal to the control component 50, and the control component 50 opens the waterway electronic switch 30 according to the signal.

The control method of the water outlet device in the embodiment comprises the following steps:

the control component 50 turns on the waterway electronic switch 30 according to the received water use signal;

the detection component 60 detects that an effective closing signal is sent to the control component 50, the control component 50 closes the electronic waterway switch 30, and the effective closing signal is that the detection component 60 detects that the flow rate of the flow rate regulating component 20 is reduced to a first position (the flow rate regulating component 20 is changed to the first position from a position where the flow rate is greater than the flow rate corresponding to the first position), and the flow rate corresponding to the first position is greater than zero.

In this embodiment, as shown in fig. 4, the flow regulating assembly 20 is a flow regulating mechanical valve controlled by a knob, and the flow of the effluent is changed by rotating the knob to change the opening of the flow regulating mechanical valve. The knob is rotatable between a closed position a and a fully open position C with a first position B therebetween. The flow increases when the knob is rotated counterclockwise and decreases when the knob is rotated clockwise. Correspondingly, the detecting component 60 may be an angle sensor for detecting the rotation angle of the knob. But not limited to this, the flow adjusting assembly 20 can also be used in other manners, such as controlling the flow of discharged water by the rotation of a motor.

The electronic sensing assembly described herein functions to sense a water usage signal and send the signal to the control assembly 50 to control the electronic waterway switch 30. The electronic sensing component may include one or more of a sensing module 41 for sensing a proximity signal, a touch module 42 for sensing a touch signal, a wireless remote control module, a gesture control module, and the like. Thus, the water use signal may be a contact or non-contact signal, including but not limited to: the detecting component 60 detects that the flow rate adjusting component 20 moves to a position where the flow rate is greater than the flow rate corresponding to the first position through the first position, the sensing module 41 senses the proximity signal, and the touch module 42 senses the touch signal, and the corresponding actions are represented as rotating a knob, approaching a human body or an object, touching a related element, and the like.

In this embodiment, the electronic sensing assembly includes a sensing module 41 for sensing a proximity signal and a touch module 42 for sensing a touch signal. Specifically, when a human body or an object enters the sensing area of the sensing module 41, the sensing module 41 sends a signal to the control component 50, and the control component 50 turns on the waterway electronic switch 30; when a human body or an object leaves the sensing area of the sensing module 41, the sensing module 41 sends a signal to the control component 50, and the control component 50 turns off the electronic waterway switch 30. When the touch module 42 is touched, the touch module 42 sends a signal to the control unit 50, and the control unit 50 turns on or off the waterway electronic switch 30.

Therefore, in the present embodiment, the touch module 42, the sensing module 41 and the detecting element 60 can all send signals to the control element 50, and the control element 50 controls the water path electronic switch 30 according to the signals. For the signal control of the waterway electronic switch 30, the priority order is: the detection element 60 is equal to the touch module 42 and has priority over the sensing module 41, and the sensing operation is only effective when the waterway electronic switch 30 is turned off.

Referring to fig. 3, the control logic of the water outlet device of the present embodiment is:

1. when the waterway electronic switch 30 is turned off, the knob rotates counterclockwise to increase the flow rate through the first position, the detection component 60 detects an effective opening signal, the control component 50 turns on the waterway electronic switch 30, at this time, the sensing module 41 does not act, and the waterway electronic switch 30 can be turned off only when the waterway electronic switch is touched (i.e., the sensing module 42 senses the effective closing signal) or the knob rotates clockwise to the first position (i.e., the detection component 60 detects the effective closing signal).

2. When the waterway electronic switch 30 is turned off, the touch module 42 senses an effective turn-on signal, the control component 50 turns on the waterway electronic switch 30, the sensing module 41 does not act, and the waterway electronic switch 30 can be turned off only when the waterway electronic switch is turned on again (i.e., the touch module 42 senses an effective turn-off signal) or the knob is clockwise rotated to the first position (i.e., the detection component 60 detects an effective turn-off signal).

3. When the waterway electronic switch 30 is turned off, a human body or an object enters the sensing area, the sensing module 41 senses an effective turn-on signal, the control component 50 turns on the waterway electronic switch 30, and if the human body or the object leaves the sensing area (i.e., the sensing module senses an effective turn-off signal), touches (i.e., the touch module 42 senses an effective turn-off signal) or the knob rotates clockwise to a first position (i.e., the detection component 60 senses an effective turn-off signal), the waterway electronic switch 30 is turned off; after the switch is turned off, the water path electronic switch 30 is turned on only when the switch leaves the sensing area and then enters the sensing area again.

The temperature adjusting component 10 referred to in this application may be a thermostatic valve, and the waterway electronic switch 30 may be an electromagnetic valve, that is, cold water and hot water enter the thermostatic valve, flow to the flow adjusting component 20 after temperature adjustment, flow to the electromagnetic valve after adjustment, and finally flow out from the water outlet portion 70 of the water outlet device.

Preferably, the first position may also be a flow regulation interval with a flow greater than zero, i.e. the first position is not a fixed point but an interval with a minimum flow (not zero) and a maximum flow. When the detecting component 60 detects that the flow regulating component 20 changes from the position where the flow is larger than the maximum flow in the flow regulating interval to the first position, the detecting component 60 sends a signal to the control component 50, and the control component 50 closes the waterway electronic switch 30 according to the signal; when the detecting component 60 detects that the flow rate adjusting component 20 is changed from the first position to a position where the flow rate is greater than the maximum flow rate in the flow rate adjusting interval, the detecting component 60 sends a signal to the control component 50, and the control component 50 turns on the waterway electronic switch 30 according to the signal.

Preferably, in the present embodiment, the flow rate adjustment assembly 20 is provided with a physical blocking member, so that when the flow rate adjustment assembly 20 reduces the flow rate to the first position (to which the flow rate adjustment assembly 20 moves from a position where the flow rate is greater than the flow rate corresponding to the first position), the flow rate cannot directly move to the closed position due to the influence of the physical blocking member. In particular, in the present embodiment, when the knob is rotated from the fully open position C in the direction of the first position B, the knob cannot be directly rotated to the closed position a across the first position B due to the presence of the physical blocking member. Wherein the physical blocking member may be arranged such that the mechanical resistance overcome by the knob on movement from the first position B to the closed position a is substantially greater than the mechanical resistance overcome on movement from a position to the first position B where the flow rate is greater than the flow rate corresponding to the first position. The physical blocking member may also be provided such that the flow control assembly 20 may be rotated between the first position B and the fully open position C by rotating the knob at will, but the flow control assembly 20 must be moved from the first position B to the closed position a by pressing the knob and rotating it at the same time. Specific implementations of the physical barrier are not sequentially limited.

Of course, the flow regulating assembly 20 may not be set to the closed position with zero flow, i.e., flow can only be regulated between the first position and the fully open position. When the detecting component 60 detects that the flow regulating component 20 is moved to the first position, the detecting component 60 sends a signal to the control component 50, and the control component 50 closes the electronic waterway switch 30 according to the signal; when the detecting component 60 detects that the flow regulating component 20 moves from the first position to another position, the detecting component 60 sends a signal to the control component 50, and the control component 50 opens the electronic waterway switch 30 according to the signal.
