The flushing function of smart toilets is achieved by controlling the opening and closing of the flush valve. The flush valve can achieve upper flushing and lower flushing, so it needs to receive two control signals to achieve it.
[0003] It is now found that general controllers generally use integrated circuits to achieve such control, such as integrated chips and microprocessors. This solution has high requirements for microprocessors and the cost of microprocessors is also high.

As a result, the defects of this integrated circuit are high cost and difficulty in subsequent maintenance.
[0004] Therefore, a set of analog control circuits needs to be designed separately. Utility Model Content

The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0023] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings.
[0024] Example:
[0025] The present application embodiment discloses an analog control circuit applied to a smart toilet, referring to Figure 1 As shown, it includes a voltage source, a flush button 300, a diode D10, a capacitor C5, a transistor switch circuit five, a transistor switch circuit two, a transistor switch circuit ten, and a voltage stabilizing circuit. The voltage source is VCC12V, indicating that the power supply voltage is 12V. The transistor switch circuit five includes a resistor R17, a resistor R18 and a transistor Q5, and the transistor Q5 is a PNP transistor. It is an existing means for the transistor switch circuit to realize the switch on and off function through a resistor device, which will not be repeated here. It should be noted here that, with respect to the transistor switch circuit five, the control end is the base end of the transistor, the first execution end is the collector of the transistor, and the second execution end is the emitter of the transistor, which are represented in sequence, mainly for the convenience of explaining the principle. By controlling the high and low levels of the base, the transistor can be turned on or off, that is, the first execution end and the second execution end are controlled to be connected or cut off (turned off). From this, it can be deduced by analogy, and other transistor switch circuits can be better and easier to understand.
[0026] The voltage source is connected to one end of the flush button 300, one end of the transistor switch circuit 2, and one end of the transistor switch circuit 10. The other end of the flush button 300 is connected to the anode of the diode D10 and the control end of the transistor switch circuit 5. The first execution end of the transistor switch circuit 5 is connected to the control end of the transistor switch circuit 2. The second execution end of the transistor switch circuit 5 is grounded. The cathode of the diode D10 is connected to one end of the capacitor C5 and the control end of the transistor switch circuit 2. The other end of the capacitor C5 is grounded. The second execution end of the transistor switch circuit 2 is grounded. The first execution end of the transistor switch circuit 2 is connected to the control end of the transistor switch circuit 10. The second execution end of the transistor switch circuit 10 serves as the first output end. The first output end is connected to the voltage stabilizing circuit.
[0027] When the flush button 300 is pressed, the current passes through the diode D10 to store energy in the capacitor C5. After the capacitor C5 stores energy, it maintains a high voltage state at one end. The transistor switch circuit 5 is turned on, so that the transistor switch circuit 2 is turned off. The flush button 300 is reset, the transistor switch circuit 5 is turned off, and the capacitor C5 releases energy to drive the transistor switch circuit 2 to turn on. The transistor switch circuit 10 is turned on to achieve the output of the first output terminal signal. When the capacitor C5 finishes releasing energy, the transistor switch circuit 10 is turned off, and the first signal 500 of the first output terminal stops. Here, the first signal 500 is also represented as OUT1 in the figure.
[0028] exist Figure 1 The voltage stabilizing circuit is also shown, and the voltage stabilizing circuit here includes a capacitor C1 and a diode D2, which are connected in parallel. The anode of the diode D2 is grounded, and the cathode of the diode D2 is connected to the first output terminal. Through this voltage stabilizing circuit, the output signal, the first signal 500, has a more stable voltage.
[0029] refer to Figure 2 As shown, it also includes a secondary control circuit 100, which includes a diode D5, a diode D7, a capacitor C6, a transistor switch circuit three, a transistor switch circuit eleven, a capacitor C10 and a transistor switch circuit eight; the input end of the secondary control circuit 100 is connected to the first output end, the anode of the diode D5 serves as the input end of the secondary control circuit 100, the cathode of the diode D5 is connected to the anode of the diode D5, the first end of the capacitor C10 and the control end of the transistor switch circuit eight, the second execution end of the transistor switch circuit eight is grounded, the first execution end of the transistor switch circuit eight is connected to the control end of the transistor switch circuit eight, the cathode of the diode D7 is connected to one end of the capacitor C6 and the control end of the transistor switch circuit three, the other end of the capacitor C6 and the second execution end of the transistor switch circuit three are grounded, the first execution end of the transistor switch circuit three is connected to the control end of the transistor switch circuit eleven, the first execution end of the transistor switch circuit eleven is connected to the voltage source, the second execution end of the transistor switch circuit eleven serves as the third output end, and the third output end is used to output the third signal 600.
[0030] It can be seen from the above connection structure that when the secondary control circuit 100 receives the first signal 500, capacitors C6 and C10 store energy, transistor switch circuit eight is turned on, and transistor switch circuit three is turned off. After the first signal 500 is turned off, capacitor C10 discharges with a delay, and capacitor C6 discharges to drive transistor switch circuit three to turn on, and transistor switch circuit eleven to turn on, thereby outputting the third signal 600. When the discharge of capacitor C6 is completed, transistor switch circuit three is turned off, and transistor switch circuit eleven is also turned off, so that the third signal 600 is stopped.
[0031] You can also continue to refer to Figure 3 As shown, the three-level control circuit 200 is also included. The three-level control circuit 200 has the same components and connection structure as the two-level control circuit 100. The input end of the triode control circuit is connected to the output end of the third signal 600, and the output end of the three-level control circuit 200 is used to output the first signal 500. The three-level control circuit 200 is briefly described. Since the circuit structure is the same, there are some differences in connection and use. The third signal 600 is received and the first signal 500 is output.
[0032] The first signal 500 is used to control a flush valve, which is an upward flushing flush valve.
[0033] The second signal is used to control a flush valve for a downspout flush.
[0034] After the above circuits are combined as a whole, different flushing operations can be achieved according to actual triggering conditions.
[0035] Finally, you can also refer to Figure 1 As shown, the off-seat flushing circuit is also included. The off-seat flushing circuit includes a seat button 400, a diode D9, a capacitor C1, a transistor switch circuit nine, a capacitor C7, and a transistor switch circuit one, the voltage source is connected to one end of the seat button 400, the other end of the seat button 400 is connected to the anode of the diode D9, one end of the capacitor C11 and the control end of the transistor switch circuit nine, the second execution end of the transistor switch circuit nine is grounded, the first execution end of the transistor switch circuit nine is connected to the control end of the transistor switch circuit one, the cathode of the diode D9 is connected to one end of the capacitor C7 and the control end of the transistor switch circuit one, the other end of the capacitor C7 and the second execution end of the transistor switch circuit one are grounded, and the first execution end of the transistor switch circuit one is connected to the control end of the transistor switch circuit ten.
[0036] When a person sits down, the seat button 400 is closed, capacitors C11 and C7 start to store energy, and transistor Q9 is turned on to prevent Q1 from being turned on; after the person leaves, C11 starts to discharge, and when C11 is fully discharged (here, to achieve delayed flushing when the person leaves), Q9 is turned off, causing Q1 to start to be turned on, thereby causing Q10 to be turned on to control the output of the first signal 500 (the flush valve OU1 is turned on), thereby turning on the upper spray flush of the toilet. After the energy storage and discharge of C7 is completed, Q1 is turned off, causing Q10 to be turned off to control the first signal 500 to be turned off (the flush valve OUT1 is turned off), thereby turning off the long spray flush of the toilet; thereafter, a complete flush is the same as a button flush.
[0037] The transistor switch circuit includes an NMOS device. A triode or the like can also be used in the transistor switch circuit.
[0038] Embodiment 2:
[0039] Based on the first embodiment, a smart toilet is further provided, comprising the above-mentioned analog control circuit applied to the smart toilet.
[0040] From the above, we can see that: the analog circuit is used to realize signal output to cooperate with the control of the flush valve. There is no need for a single-chip microcomputer or microprocessor to connect the control, which reduces costs and does not require program control. The circuit operation is more reliable and there is no program failure. The control is simple and efficient, the response is sensitive, and the action is quick.
[0041] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
