It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
As shown in fig. 1, the touch faucet provided in the embodiment of the present application includes a battery 10, a faucet body 20, and a circuit board 40 disposed in a control box 30, where the circuit board 40 is provided with a control circuit 50. In some embodiments, the battery 10 may be a dry battery, a button battery, a rechargeable lithium battery, a lead-acid battery, or the like, for providing an operating power source for the touch faucet. In some embodiments, the faucet body 20 may include an electrically controlled valve, such as a solenoid valve, to which the control circuit 50 may be connected to effect control of the opening or closing of the faucet body 20.
As shown in fig. 2, control circuit 50 includes a controller 501, a main electrode 502, a monitor electrode 503, and a ground reference 504. Wherein the controller 501 is connected with the main electrode 502, the monitor electrode 503 and the reference ground 504, it can be understood that the controller 501 is connected with the faucet body 20 through the main electrode 502 and is connected with the housing of the control box 40 through the monitor electrode 503. In some embodiments, the reference ground 504 may be connected to the negative pole of the battery 10. Based on this, the controller 501 may acquire a first electrical signal between the faucet body 20 and the reference ground 504, and the controller 501 may also acquire a second electrical signal between the monitor electrode 503 and the reference ground 504.
Based on this, the controller 501 can control the faucet body 20 to open or close according to the first and second electrical signals. Specifically, the first electrical signal is affected by the reference ground, but in the prior art, when external interference occurs, the reference ground is affected, that is, the first electrical signal is affected, for example, the signal intensity of the first electrical signal is increased to a set water outlet threshold value, so that the controller sends a control command to the faucet body to control the faucet body to open, and a malfunction is caused. In the present application, the first electrical signal and the second electrical signal obtained by the controller 501 are both influenced by the reference ground 504, so the controller 501 can determine whether external interference occurs according to the first electrical signal and the second electrical signal, if so, the faucet body 20 is not controlled, and if not, the faucet body 20 is controlled to be opened or closed. Therefore, the touch faucet can solve the problem that the touch faucet generates misoperation due to external interference, and the reliability of the touch faucet is improved.
In some embodiments, as shown in fig. 2, both main electrode 502 and monitor electrode 503 are disposed within a copper-clad region of reference ground 504.
Specifically, in order to affect the first electrical signal and the second electrical signal simultaneously when external interference occurs, both the monitor electrode 503 and the main electrode 502 are disposed in the copper-clad area of the reference ground 504, based on the connection between the monitor electrode 503 and the housing of the control box 40. In this way, reference ground 504 is affected when external disturbances occur, thereby affecting main electrode 502 and monitor electrode 503 simultaneously, and thus affecting the first electrical signal and the second electrical signal simultaneously when external disturbances occur. Therefore, the controller 501 may determine whether external interference occurs according to the first electrical signal and the second electrical signal, if so, the faucet body 20 is not controlled, and if not, the faucet body 20 is controlled to be opened or closed, thereby improving reliability of the touch faucet. Note that the copper-plated region of the reference ground 504 is, for example, the region a in fig. 2, and the copper-plated region of the reference ground 504 is not directly electrically connected to the monitor electrode 503 and the main electrode 502.
In some embodiments, the controller 501 is configured to: and if the current signal intensity value of the first electric signal reaches a preset first threshold value and the current signal intensity value of the second electric signal does not reach a second threshold value, controlling the faucet body 20 to be opened or closed, wherein the first threshold value is larger than the second threshold value. The first threshold in the embodiment of the present application may be set as follows: in a normal situation, the faucet body 20 is manually touched multiple times, signal strength values of multiple first electrical signals are obtained, and a first threshold value is set according to the signal strength values, for example, the first threshold value is set according to an average value of the signal strength values. The second threshold in the embodiment of the present application may be set as follows: under multiple times of man-made external interference, signal strength values of multiple second electric signals are obtained, and a second threshold value is set according to the signal strength values, for example, the second threshold value is set according to an average value of the signal strength values.
When a person touches the faucet body 20 or an external disturbance occurs, the signal intensity value of the first electrical signal may be greater than or equal to the first threshold value, and thus, it is necessary to determine the cause of the change in the signal intensity of the first electrical signal. Specifically, since the first electrical signal and the second electrical signal are simultaneously affected when the external interference occurs, the controller 501 may determine whether the current signal strength value of the first electrical signal reaches the first threshold value and whether the current signal strength value of the second electrical signal reaches the second threshold value. In some embodiments, as shown in fig. 3, if the current signal strength value of the first electrical signal reaches the first threshold value and the current signal strength value of the second electrical signal does not reach the second threshold value, it may be determined that the reason causing the signal strength of the first electrical signal to change is that a person touches the faucet body 20, and thus the controller 501 may control the faucet body 20 to be turned on or off. In some embodiments, if the current signal intensity value of the first electrical signal reaches the first threshold value and the current signal intensity value of the second electrical signal reaches the second threshold value, it may be determined that the cause of the change in the signal intensity of the first electrical signal is external interference, and therefore, the controller 501 does not need to control the faucet body 20 to open or close. Therefore, the tap body 20 is controlled to be opened or closed according to the first electric signal and the second electric signal, so that the problem of misoperation of the touch tap due to external interference can be solved, and the reliability of the touch tap is improved. It should be noted that the controller 501 may detect the first electrical signal and the second electrical signal at the same time, or may detect the first electrical signal and the second electrical signal at different times, but the detection time intervals should be set reasonably when detecting at different times.
In some embodiments, the controller 501 is configured to: and if the current signal intensity value of the first electric signal reaches a preset first threshold value and keeps a preset first time length, controlling the faucet body to be opened or closed according to the second electric signal. In some embodiments, controlling the faucet body to open or close according to the second electrical signal comprises: and if the current signal intensity of the second electric signal does not reach a preset second threshold value, controlling the faucet body to be opened or closed.
When a human hand moves across the faucet body 20, the signal intensity value of the first electrical signal is temporarily greater than or equal to the first threshold value, and thus the touch faucet malfunctions. Therefore, in order to solve the malfunction problem of the touch faucet under such a situation, the controller 501 may determine whether the current signal intensity value of the first electrical signal reaches the first threshold value and keep the first time length, where the first time length may be reasonably set, such as 0.8 second, 1 second, and the like. In some embodiments, if the current signal strength value of the first electrical signal reaches the first threshold value but fails to maintain the first time period, the controller 501 does not need to control the faucet body 20 to open or close. In some embodiments, as shown in fig. 3, if the current signal intensity value of the first electrical signal reaches the first threshold and can be maintained for the first time period, the controller 501 needs to further determine the reason causing the signal intensity change of the first electrical signal, in other words, needs to control the faucet body to be opened or closed according to the second electrical signal.
Since the first electrical signal and the second electrical signal are simultaneously affected when the external interference occurs, the controller 501 may determine whether the current signal strength value of the second electrical signal reaches the second threshold value based on the current signal strength value of the first electrical signal reaching the first threshold value and being maintained for the first time period. In some embodiments, as shown in fig. 3, if the current signal intensity value of the second electrical signal does not reach the second threshold, it may be determined that the reason causing the signal intensity of the first electrical signal to change is that a person touches the faucet body 20, and thus the controller 501 may control the faucet body 20 to be turned on or off. In some embodiments, if the current signal intensity value of the second electrical signal reaches the second threshold, it may be determined that the cause of the change in the signal intensity of the first electrical signal is an external disturbance, and therefore the controller 501 does not need to control the faucet body 20 to open or close. Therefore, the tap body 20 is controlled to be opened or closed according to the first electric signal and the second electric signal, so that the problem of misoperation of the touch tap due to external interference can be solved, and the reliability of the touch tap is improved.
In some embodiments, the controller 501 is configured to: and sending a corresponding control command to the faucet body 20 according to the current state of the faucet body 20 so as to control the faucet body 20 to be opened or closed. In some embodiments, sending a corresponding control command to the faucet body 20 according to the current state of the faucet body 20 to control the faucet body 20 to open or close includes: if the current state of the faucet body 20 is a closing state, an opening instruction is sent to the faucet body to control the faucet body 20 to be opened; if the current state of the faucet body 20 is the open state, a close command is sent to the faucet body 20 to control the faucet body 20 to close.
Specifically, the controller 501 may send a control instruction to the faucet body 20 to control the faucet body 20. Therefore, the corresponding control command may be sent according to the current state of the faucet body 20, for example, if the current state of the faucet body 20 is the off state, the on command is sent, and if the current state is the off state, the on command is sent.
In some embodiments, the controller 501 is configured to: after the faucet body 20 is controlled to be opened, if a closing command is not sent to the faucet body 20 after a preset second time period, a closing command is sent to the faucet body 20 to control the faucet body 20 to be closed.
After the user opens the touch faucet, the user may forget to close the touch faucet for some reasons, and therefore, after controlling the faucet body 20 to be opened, if a closing instruction is not sent to the faucet body 20 within the second time period, the controller 501 sends a closing instruction to the faucet body 20, and controls the faucet body 20 to be closed.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
