As shown in fig. 1, fig. 1 schematically illustrates a block diagram of a shower control device 100 according to an embodiment of the present application. The shower control device 100 may be powered by a power supply 10. In the embodiment of the present application, the power source 10 may be, but is not limited to, a lithium battery, a dry battery, a button battery, etc. The shower control device 100 includes a key unit 110, a switch unit 120, a power-off auxiliary unit 130, and a control unit 140. The switch unit 120 is connected between the control unit 140 and the power source 10, the switch unit 120 is connected to the key unit 110, and the power-off assisting unit 130 is connected between the key unit 110 and the power-off assisting unit 130. In this embodiment, the switch unit 120 is controlled by the key unit 110 for powering on the control unit 140; the power-off assisting unit 130 is used for detecting a key change state of the key unit 110; the control unit 140 is configured to determine whether the key state of the key unit 110 is an off state according to the key change state and a preset change state, and control the switch unit 120 to power off the control unit 140 when the key state is off.

In this embodiment, the key states of the key unit 110 may include an on state and an off state. When the key unit 110 is in the on state, the key unit 110 may control the switch unit 120 to turn on the connection between the control unit 140 and the power source 10, so that the control unit 140 is powered on. When the key unit 110 is in the off state, the power-off assisting unit 130 may detect a key change state of the key unit 110, and determine whether the key change state matches a preset change state through the control unit 140, and if so, may determine that the key state of the key unit 110 is in the off state, and at this time, the control unit 140 may control the switch unit 120 to disconnect the connection between the control unit 140 and the power supply 10. For example, when the key unit 110 is triggered, the key unit 110 is in an on state, and at this time, the key unit 110 can control the switch unit 120 to conduct the connection between the control unit 140 and the power source 10, so that the control unit 140 is powered on.

It can be understood that when the key unit 110 is in the on state, the shower head is in the use state; when the key unit 110 is in the off state, it indicates that the shower head is in the non-use state. Therefore, the shower control device 100 provided by the embodiment of the application can enable the shower to be powered off when not in use without consuming the electric quantity of the battery, thereby improving the cruising ability of the shower. Simultaneously, can make the gondola water faucet need not frequently to change the battery or frequently charge to improve the life of gondola water faucet.

Specifically, as shown in fig. 2, the key unit 110 may be a button (the button may be a tact switch, a mechanical switch, a magnetic tunnel switch, a hall switch, or the like), and the control unit 140 includes a power supply terminal, a power supply control terminal, and a state detection terminal. The switch unit 120 includes a power switch circuit 121 and a power-on auxiliary circuit 122, wherein the power switch circuit 121 is connected between the power source 10 and a power source end and is controlled by a button to turn on the connection between the power source 10 and the power source end; the power-on auxiliary circuit 122 is connected between the power switch circuit 121 and the power control end; the control unit 140 is further configured to output a power-on maintaining signal to the power-on auxiliary circuit 122 when the power supply is powered on, and the power-on auxiliary circuit 122 is configured to control the power switch circuit 121 to maintain the connection with the power source terminal according to the power-on maintaining signal.

In this embodiment, when the button is pressed, the switch unit 120 is turned on, so that the power supply 10 is connected to the power end of the control unit 140, and the control unit 140 is powered on; when the control unit 140 is powered on, the control unit 140 immediately outputs a power-on maintaining signal to the power-on auxiliary circuit 122, and the power-on auxiliary circuit 122 receives the power-on maintaining signal and then continuously turns on the switch unit 120, so that when the button is released, the power supply 10 and the control unit 140 can be kept connected, and the control unit 140 is kept in a power-on state.

Further, the power-off auxiliary unit 130 is configured to detect a key change state of the button to output a state detection signal to the state detection terminal; the control unit 140 is further configured to determine whether the key state of the button is the off state according to the level change of the state detection terminal and the preset level change, and output a power-off signal to the power-on auxiliary circuit 122 when the key state is the off state, so that the power-on auxiliary circuit 122 controls the power switch circuit 121 to disconnect the power supply 10 from the power supply terminal.

In this embodiment, the power-off assisting unit 130 may assist the control unit 140 to power off by detecting a key change state of the button. Specifically, the button change state of the button includes a pressed state and a released state, and when the button is operated once, the button change state of the button is a released state, a pressed state and a released state, at this time, the power-off assisting unit 130 may detect the button change state of the button and output a state detection signal to the state detection terminal of the control unit 140, so that the level of the state detection terminal is changed accordingly, and the level change is also the preset level change in the present embodiment. When the user powers on the control unit 140 by operating the button to use the shower head, the control unit 140 detects that the level change of the state detection state corresponds to the preset level change, and the button state of the button can be determined as the on state. When the button of the button is in the on state, if the control unit 140 detects that the level change of the state detection end matches the preset level change again, that is, it indicates that the button is operated again and turned off, the control unit 140 may determine the button of the button to be in the off state, and output a power-off signal to the power-on auxiliary circuit 122, and the power-on auxiliary circuit 122, after receiving the power-off signal, turns off the switch unit 120, and further turns off the connection between the power supply 10 and the control unit 140, so as to turn off the power of the control unit 140. Therefore, when the shower head is not in a use state, the electric quantity of the battery is not required to be continuously consumed, and the cruising ability of the shower head is further improved.

Specifically, the power-on assist circuit 122 further includes a resistor R4; the collector of the triode Q2 is connected between the resistor R2 and the key unit 110, the emitter is grounded, the base is connected with one end of the resistor R4, and the other end of the resistor R4 is connected with the pin B of the MCU; the pull-down resistor R3 is connected between the base and emitter of transistor Q2.

The key unit 110 is a button S0. In this embodiment, the shower control device 100 further includes a protection circuit 150. The protection circuit 150 includes a first diode D1, a second diode D2, a resistor R5, and a resistor R6. The anode of the first diode D1 is connected to the base of the first transistor Q1 through a resistor R2, the cathode of the first diode D1 is connected to the cathode of the second diode D2, the anode of the second diode D2 is connected in series to a resistor R5 and a resistor R6, and the other end of the resistor R6 is connected to the power-off assisting unit 130.

In this embodiment, if the shower head is controlled to operate, when the button S0 is pressed to make the button S0 in a pressed state, the base of the transistor Q1 is grounded, the base voltage of the transistor Q1 is reduced to turn on the transistor Q1, and the pin a of the MCU is connected to the battery BAT. At this time, the MCU outputs a high level signal to the transistor Q2 through the pin B, turning on the transistor Q2. The conduction of transistor Q2 causes the base of transistor Q1 to remain connected to ground, so that when the button S0 is released, transistor Q1 remains on and the battery BAT continues to provide power 10 to the MCU. It should be noted that, at this time, the shower head is in the working state, and the button state of the button S0 is the on state.

Further, in the process of operating the button once, when the button S0 is pressed to make the button S0 in a pressed state, the voltage at the base of the transistor Q3 is changed from high to low, so that the transistor Q3 is turned on, and the level state of the pin C of the MCU is changed from low to high. When the button S0 is released, the voltage at the base of the transistor Q3 goes from low to high, so that the transistor Q3 is turned off, and the level state of the pin C of the MCU changes from high to low. Therefore, when the button is operated once, the level change state of pin C of the MCU is low-high-low. In this embodiment, the preset level change state of the pin C is low-high-low.

In this embodiment, when the control unit 140 is powered on, if the level change state of the pin C meets the above-mentioned low-high-low, the variable may be defined as 1, that is, the key state of the button S0 is determined to be the on state; on this basis, if it is detected again that the level change state of the pin C is consistent with the low-high-low state, the variable 0 may be defined, that is, the key state of the button S0 may be determined to be the off state, which indicates that the user operates the button S0 again to turn off the shower head, so that the control unit 140 outputs a low level signal to the transistor Q2 through the pin B, so as to turn off the transistor Q2, and further turn off the transistor Q1 from the low to the high voltage of the base of the transistor Q1, thereby disconnecting the MCU from the battery BAT. From this, can improve the duration of a journey ability of gondola water faucet, can reduce the number of times of changing the battery or the number of times that the battery charges simultaneously, improve the life of gondola water faucet.

Specifically, the key unit 110 may include a plurality of buttons, and the user may control the shower to be turned on and off through any one of the buttons.

The control unit 140 of fig. 5 is different from the control unit 140 of fig. 3 in that the control unit 140 of fig. 5 includes two state detection terminals including a state detection terminal C1 and a state detection terminal C2. The state detection terminal C1 is connected to the first state detection circuit 131, and the control unit 140 can determine the key state of the button S1 through the level change of the state detection terminal C1; the state detection terminal C2 is connected to the second state detection circuit 132, and the control unit 140 can determine the key state of the button S2 through the level change of the state detection terminal C2.

Specifically, the first state detecting circuit 131 makes the control unit 140 know the key state of the button S1 by detecting the key change state of the button S1, and likewise, the second state detecting circuit 132 makes the control unit 140 know the key state of the button S2 by detecting the key change state of the button S2. When at least one of the buttons S1 and S2 is turned on, the power switch circuit 121 can turn on the power source 10 and the control unit 140, so that the control unit 140 is powered on and outputs a power-on maintaining signal to the power-on auxiliary circuit 122 to maintain the power-on state of the control unit 140. When the button states of the button S1 and the button S2 are both off states, the control unit 140 outputs a power-off signal to the power-on auxiliary circuit 122 to power off the control unit 140. Further, the preset logic rules may specifically refer to table 1 below. Wherein, the button "1" represents that the button is in an on state, and the button "0" represents that the button is in an off state; the variable "1" indicates that the control unit 140 does not output the power-down signal but maintains the power-on state, and the variable "0" indicates that the control unit 140 outputs the power-down signal but powers down.
