Detailed Description
In order to make the technical field person understand the scheme of the present invention better, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical scheme in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of some, and not necessarily all, embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by the skilled person without creative work belong to the protection scope of the present invention.
The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an embodiment of the present invention provides a flushing control device 100, and the flushing control device 100 may be applied to flushing apparatuses such as a toilet, a squatting pan, a urinal, and a shower, and is used to implement a flushing function of the flushing apparatuses.
The flushing control device 100 comprises a solenoid valve 10, a pressure sensor 30 and a controller 50, wherein the controller 50 is electrically connected with the solenoid valve 10 and the pressure sensor 30 respectively so as to facilitate signal transmission between the controller 50 and the solenoid valve 10 and the pressure sensor 30.
The electromagnetic valve 10 is provided with a water inlet channel 111 and a water outlet channel 113, wherein the water inlet channel 111 is used for being communicated with a water inlet source, and the water outlet channel 113 is used for being communicated with a water outlet device of the flushing device. The solenoid valve 10 may include a valve seat 11 and a valve head 13, and the water inlet passage 111 and the water outlet passage 113 of the solenoid valve 10 are both opened to the valve seat 11. The valve head 13 is mounted on the valve seat 11 and is located between the water inlet passage 111 and the water outlet passage 113.
The solenoid valve 10 may be a pulsed solenoid valve such that the solenoid valve 10 may perform a corresponding action according to the received pulse signal. The pulse signals may include an open valve pulse signal and a close valve pulse signal. For example, the electromagnetic valve 10 communicates the water inlet channel 111 with the water outlet channel 113 according to the received valve opening pulse signal and is in a valve opening state, and the valve head 13 in the valve opening state communicates the water inlet channel 111 with the water outlet channel 113; the solenoid valve 10 blocks the water inlet channel 111 and the water outlet channel 113 according to the received valve closing pulse signal and is in a valve closing state, and the valve head 13 in the valve closing state blocks the water inlet channel 111 and the water outlet channel 113.
The pressure sensor 30 is mounted to the solenoid valve 10 and is located in the outlet passage 113, for example, the pressure sensor 30 is mounted to the valve seat 11 and spaced from the valve head 13. The pressure sensor 30 outputs the outlet pressure signal according to the detected water pressure of the outlet channel 113, for example, when the electromagnetic valve 10 is in a valve closing state, because the outlet channel 113 of the inlet channel 111 is blocked, water does not flow into the outlet channel 113, and the pressure sensor 30 located in the outlet channel 113 does not detect the corresponding water pressure, at this time, the pressure sensor 30 may not output the outlet pressure signal, and may also output the outlet pressure signal corresponding to the water pressure value of 0. For example, when the solenoid valve 10 is in the open state, the water inlet channel 111 communicates with the water outlet channel 113, so that water flows into the water outlet channel 113 through the water inlet channel 111, and the pressure sensor 30 located in the water outlet channel 113 can detect a corresponding water pressure and output a water outlet pressure signal. In the present embodiment, the pressure sensor 30 is disposed in the water outlet channel 113, which is more helpful for the pressure sensor 30 to detect the change of the outlet water pressure of the water outlet channel 113, and is helpful for improving the response accuracy of the flushing control device 100.
The controller 50 can receive the water outlet pressure signal sent by the pressure sensor 30, and can execute the next step or not according to the water outlet pressure signal; the controller 50 may also send out a valve opening pulse signal to control the solenoid valve 10 to be in a valve opening state according to the received related control signal, and may also send out a valve closing pulse signal to control the solenoid valve 10 to be in a valve closing state. The related control signals can be obtained by sensors, for example, the flushing control device 100 can further include a human body sensor 70, the human body sensor 70 is electrically connected to the controller 50, and the human body sensor 70 and the controller 50 can be mounted on the same supporting substrate. The human body sensor 70 outputs a sensing signal to the controller 50 according to the detected human body, so that the controller 50 can output a valve-opening pulse signal or a valve-closing pulse signal to the solenoid valve 10 according to the sensing signal to control the opening or closing of the solenoid valve 10. The human body sensor 70 may be an infrared ray sensor.
The controller 50 outputs a valve opening pulse signal to the solenoid valve 10 according to the solenoid valve opening signal until the outlet water pressure signal received by the controller 50 exceeds the outlet water pressure threshold, which indicates that the valve opening pulse signal output by the controller 50 changes the solenoid valve 10 from the valve closing state to the valve opening state, and at this time, the continuous output of the valve opening pulse signal can be stopped, so that the electric quantity is saved as much as possible under the condition that the solenoid valve 10 is ensured to be opened, and the actual power consumption of the flushing control device 100 is also reduced. The controller 50 also outputs a valve-closing pulse signal to the solenoid valve 10 according to the solenoid valve-closing signal.
Different functional modules may be disposed in the controller 50, so that the controller 50 may implement corresponding control functions through cooperation of the different functional modules.
The controller 50 may include a water pressure module 51 and a pulse module 53, wherein the water pressure module 51 may receive the output water pressure signal from the pressure sensor 30 and process the output water pressure signal, the pulse module 53 is electrically connected to the water pressure module 51, and the pulse module 53 may receive the output signal from the water pressure module 51 and process the output signal. The controller 50 may further include a control module 55, and the control module 55 may receive the sensing signal from the human body sensor 70 and process the sensing signal. The control module 55 is electrically connected to the pulse module 53 such that the pulse module 53 can receive the signal output by the control module 55 and process the signal.
When the control module 55 receives the sensing signal, which indicates that the human body is using the flushing device, the control module 55 may send a solenoid opening signal to the pulse module 53, so that the pulse module 53 performs the next processing. When the control module 55 does not receive the sensing signal, which indicates that the human body does not use the flushing device or leaves the flushing device, the control module 55 may send a solenoid valve closing signal to the pulse module 53, so that the pulse module 53 performs the next processing.
The water pressure module 51 can output a water pressure comparison result to the pulse module 53 according to the outlet water pressure signal and the outlet water pressure threshold value, so that the pulse module 53 can perform the next processing. The water pressure comparison result comprises two results, wherein the first result is that the water outlet pressure signal exceeds the water outlet pressure threshold value, and the second result is that the water outlet pressure signal does not exceed the water outlet pressure threshold value. In the present embodiment, the outlet water pressure threshold may be 0, and when the outlet water pressure signal exceeds 0, it indicates that the electromagnetic valve 10 is in an open state; when the water outlet pressure signal does not exceed 0, that is, the water outlet pressure signal is 0, it indicates that the electromagnetic valve 10 is in a valve-closing state. When the positive and negative connection directions of the pressure sensor 30 are adjusted, if the outlet water pressure signal output by the pressure sensor 30 is a negative value, the water pressure module 51 outputs a comparison result that the outlet water pressure signal exceeds 0.
The pulse module 53 may output an open-valve pulse signal to the solenoid valve 10 according to the received solenoid valve open signal, and may also output a close-valve pulse signal to the solenoid valve 10 according to the solenoid valve close signal. Whether the electromagnetic valve 10 can be opened or closed smoothly after receiving the valve opening pulse signal or the valve closing pulse signal is influenced by water pressure of water in different areas, so that the waste of electric quantity is further reduced, a mode of adopting a minimum pulse signal and gradually increasing the width of the pulse signal can be adopted for testing, and a proper valve opening pulse signal can be obtained.
For example, the pulse module 53 outputs a first valve-opening pulse signal as a valve-opening pulse signal to the solenoid valve 10 according to the solenoid valve opening signal. The first valve-opening pulse signal may be a minimum value for opening the solenoid valve 10 in a normal pressure state.
After the pulse module 53 outputs the first valve opening pulse signal, the water pressure module 51 outputs a water pressure comparison result according to the received outlet water pressure signal, and the pulse module 53 adjusts the pulse width of the valve opening pulse signal output to the solenoid valve 10 according to the water pressure comparison result. For example, the pulse module 53 may indicate that the first valve opening pulse signal causes the solenoid valve 10 to be in the valve opening state according to the water pressure comparison result that the outlet water pressure signal exceeds the outlet water pressure threshold, and at this time, the pulse module 53 may stop outputting the valve opening pulse signal, so that the flushing control device 100 may open the solenoid valve 10 with the pulse signal with smaller energy, which is beneficial to saving electric power.
For example, the pulse module 53 may output a second valve opening pulse signal as the valve opening pulse signal to the solenoid valve 10 based on the water pressure comparison result that the discharge water pressure signal does not exceed the discharge water pressure threshold, wherein the pulse width of the second valve opening pulse signal is larger than the pulse width of the first valve opening pulse signal, and the larger the pulse width of the pulse signal is, the larger the energy of the second valve opening pulse signal received by the solenoid valve 10 is, the larger the energy of the first valve opening pulse signal is.
After the pulse module 53 outputs the second valve opening pulse signal, if the water pressure module 51 outputs the water pressure comparison result that the outlet water pressure signal is greater than the outlet water pressure threshold value according to the received outlet water pressure signal, it indicates that the second valve opening pulse signal causes the solenoid valve 10 to be in the valve opening state, at this time, the pulse module 53 may stop outputting the valve opening pulse signal, which helps the solenoid valve 10 to be opened without outputting the maximum valve opening pulse signal of the pulse signal, and thus the electric quantity is saved.
After the pulse module 53 outputs the second valve opening pulse signal, if the water pressure module 51 outputs the water pressure comparison result that the outlet water pressure signal is less than or equal to the outlet water pressure threshold according to the received outlet water pressure signal, it indicates that the second valve opening pulse signal is insufficient to open the solenoid valve 10, at this time, the pulse module 53 may output a third valve opening pulse signal having a pulse width greater than the second valve opening pulse signal as the valve opening pulse signal to the solenoid valve 10, after the pulse module 53 outputs the third valve opening pulse signal, the water pressure module 51 outputs the water pressure comparison result, and the pulse module 53 and the water pressure module 51 are repeatedly operated until the outlet water pressure signal received by the controller 50 is greater than the outlet water pressure threshold.
In addition, the water pressure module 51 is configured to store the optimized outlet water pressure, and the water pressure module 51 may record and store the outlet water pressure corresponding to the outlet water pressure signal received each time the electromagnetic valve 10 is successfully opened, and form the optimized outlet water pressure by using a plurality of outlet water pressures. For example, the water pressure module 51 may use a binary number of the outlet water pressures corresponding to the plurality of outlet water pressure signals as the optimized outlet water pressure. The pulse module 53 can store the optimized valve opening pulse signal corresponding to the optimized outlet water pressure, so that the pulse module 53 outputs the optimized valve opening pulse signal to the solenoid valve 10 according to the received solenoid valve opening signal, which is helpful for shortening the process of repeatedly determining the optimal pulse width, further saving electric quantity, and reducing unnecessary power consumption.
The flush control device 100 may also include a filter 90, the filter 90 being located in the water inlet passage 111. The filter 90 can not only filter impurities in water, but also prevent excessive impurities from entering the water outlet channel 113 of the electromagnetic valve 10, so that the impurities can be prevented from accumulating on the pressure sensor 30 located in the water outlet channel 113, the interference to the pressure sensor 30 can be reduced, and the accuracy of detection of the pressure sensor 30 can be improved.
The flush control device 100 may further include a flow control valve 80, the flow control valve 80 is mounted on the valve seat 11 and located in the water inlet channel 111, and the flow control valve 80 can adjust the water flow rate, so as to adjust different water outlet amounts. The filter 90 may be attached to the flow rate adjustment valve 80, which helps to reduce the amount of space occupied by the filter 90 in the solenoid valve 10, and helps to facilitate miniaturization of the flush control device.
Referring to fig. 2, the flushing control device 100 may further include a battery 70, and the battery 70 may be electrically connected to the controller 50 through a wire, so that the battery 70 may supply power to the controller 50. Since the controller 50 is also electrically connected to the solenoid valve 10, the pressure sensor 30, and the like, respectively, the electric power output from the battery 70 can be transmitted to the solenoid valve 10, the pressure sensor 30, respectively, through the controller 50. Wherein the battery 70 may be a secondary battery, a dry cell battery, a lithium battery, or the like. Because the controller 50 outputs the valve opening pulse signal to the solenoid valve 10 according to the solenoid valve opening signal until the outlet water pressure signal received by the controller 50 exceeds the outlet water pressure threshold value, the service life of the battery 70 is prolonged, and the frequency of replacing the battery 70 is reduced.

The embodiment of the utility model provides an among the flushing device, solenoid valve 10 communicates inlet channel 111 and exhalant canal 113 and is in the open valve state according to the valve pulse signal that opens that receives to and close valve pulse signal according to receiving and block inlet channel 111 and exhalant canal 113 and be in the valve state of closing, and pressure sensor 30 exports out water pressure signal according to the water pressure of the exhalant canal 113 that detects. Because the controller 50 outputs the valve opening pulse signal to the solenoid valve 10 according to the solenoid valve opening signal until the outlet water pressure signal received by the controller 50 exceeds the outlet water pressure threshold, the valve opening pulse signal output by the controller 50 indicates that the solenoid valve 10 is changed from the valve closing state to the valve opening state, the electric quantity is saved as much as possible under the condition that the solenoid valve 10 is ensured to be opened, the actual power consumption of the flushing control device 100 is also reduced, the service life of a battery for supplying power to the flushing control device 100 is prolonged, and the frequency of battery replacement is reduced. In addition, by disposing the pressure sensor 30 in the water outlet channel 113, the pressure sensor 30 can detect the pressure change of the channel, which is more beneficial than the position of the water inlet channel 111, and the response accuracy of the flushing control device 100 can be improved.
