Description

[0001] The utility model relates to the technical field of toilet bowl, especially a closing cover flushing system and intelligent closestool. BACKGROUND

[0002] With the improvement of people's living standards, intelligent closestools are widely used due to their convenience and hygiene. Intelligent closestools are usually equipped with multiple functions, such as automatic flushing, drying, seat heating, etc. These functions mostly rely on mains power supply. However, in some special situations, such as power failure or environments without mains power supply, users still need to use the flushing function of the closestool, which requires battery power supply to realize the flushing function without mains power supply.

[0003] Currently, the existing intelligent closestools usually use touch buttons to control the flushing function in the state without mains power supply. This design has some problems: in the state without mains power supply, the battery needs to continuously supply power to the touch button panel, so that the touch button is in a continuous standby state. This not only increases the static power consumption, but also significantly shortens the available life of the battery. For example, some intelligent closestools using touch buttons may have a standby time of only a few days or even shorter in the state without mains power supply, which greatly limits the convenience of using the intelligent closestool in the environment without mains power supply.

[0037] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0038] Reference Figure 1 A lid closing flushing system, comprising an energy storage module, a first switch module, a trigger module, a second switch module, and a master control module.

[0039] The energy storage module is used for storing electric energy and providing a power source, such as a dry battery, a storage battery, or a super capacitor.

[0040] The first switch module is connected with the energy storage module, and when the first switch module is turned on, the energy storage module can discharge externally.

[0041] The trigger module is connected with the control end of the first switch module, and the trigger module is used for rotating to a preset angle when the lid body is closed, sending a first control signal to the first switch module, controlling the first switch module to be turned on, and enabling the energy storage module to discharge through the first switch module. That is, only the rotating process of the closed lid body can trigger the energy storage module to discharge, and it is not necessary to continuously supply power to the trigger module to keep it in standby, so that the use time and service life of the energy storage module (such as a battery) can be greatly improved.

[0042] The second switch module is connected with the output end of the first switch module and the energy storage module respectively, the first switch module is used for controlling the on-off of the second switch module, and the energy storage module discharges externally through the second switch module. In the embodiment, during the closing process, the first switch module is turned on, so that the energy storage module and the control end of the second switch module are turned on, the second switch module is controlled to be turned on, and the energy storage module is controlled to output electric energy externally through the second switch module.

[0043] The main control module is connected with the control end of the second switch module and the output end of the second switch module, and the flushing execution assembly is connected with the output end of the second switch module and the main control module. When the second switch module is turned on, the energy storage module supplies power to the main control module and the flushing execution assembly through the second switch module. The main control module completes initialization before the first switch module is turned off. The main control module controls the second switch module to be continuously turned on and controls the flushing execution assembly to perform flushing action. The main control module controls the second switch module to be turned off after T time (after flushing is completed), and the whole machine is powered off. Each module does not need to standby or sleep, and the use time of the energy storage module can be effectively prolonged.

[0044] It is worth noting that the main control module is powered on and initialized after the second switch module is turned on. The main control module outputs a control signal (such as a high-level signal) to the control end of the second switch module, so that the second switch module can continue to be turned on after the cover is closed and rotated to a preset angle and the first switch module is turned off. After T time, the main control module outputs another control signal (such as a low-level signal) to control the second switch module to be turned off, so that the whole machine is powered off. The control technology of the main control module outputting a control signal for T time and then outputting another control signal is a conventional technology in the field of automatic control.

[0045] The time T can be realized by a clock component of the main control module. For example, when the main control module is initialized, the main control module sets the counting period to T. When the counting reaches the set value, an interrupt or a flag is triggered. After the main control module detects the interrupt signal, the main control module switches the control signal to the second switch module. Of course, the time T can also be realized by other technical means, such as a 555 timer, a software delay function, an external crystal oscillator or a clock module. These are all prior art, and will not be described here.

[0046] Referring to Figure 2 The cover-closed flushing system further comprises a commercial power module and a third switch module. The commercial power module is connected to commercial power and outputs a power supply. The power supply output by the commercial power module can be one or more power supplies with different voltage values, which can be realized by an ACDC chip and one or more DCDC chips, and can meet the power supply requirement. The third switch module is connected with the output end of the commercial power module and the common end of the first switch module and the second switch module, that is, the control end of the second switch module. When there is commercial power, the third switch module controls the second switch module to be turned off, thereby avoiding the energy storage module from supplying power to the main control module and the execution assembly and reducing the consumption of the energy storage module. The commercial power module is connected with the first switch module, the main control module and the execution assembly to supply power to them. When there is no commercial power, the third switch module is not connected to the circuit, and does not affect the working state of the second switch module.

[0047] The common end of the commercial power module and the first switch module is connected with the master control module. When the trigger module sends a first control signal to the first switch to make the first switch module conductive, the electrical signal of the line between the commercial power module and the first switch module changes, and the master control module collects the electrical signal to determine whether there is a closing cover action, and then controls the execution assembly to act. Thus, when the commercial power is connected to the closing cover flushing system, the closing cover flushing function can be realized.

[0048] Referring to Figure 3 The embodiment provides a circuit principle capable of realizing the closing cover flushing function.

[0049] The trigger module 20 comprises a mechanical switch J2 associated with the cover rotating shaft. One end 1 of the mechanical switch J2 is connected with the control end of the first switch module 30, and the other end 2 of the mechanical switch J2 is grounded. When the cover is closed to a preset angle, the mechanical switch J2 is closed, the 1 end and the 2 end of the mechanical switch J2 are conductive, the 1 end of the mechanical switch J2 is grounded, and the control end of the first switch module 30 is pulled down.

[0050] The first switch module 30 comprises a first switch tube Q1. In the embodiment, the first switch tube Q1 is a PNP triode. The base of the first switch tube Q1 is connected with the 1 end of the mechanical switch J2, and the trigger module is connected. The emitter of the first switch tube Q1 is connected with the energy storage module 10, and the collector of the first switch tube Q1 is connected with the control end of the second switch module 40. When the first switch tube Q1 is closed, the first switch tube Q1 is conductive, and the energy storage module 10 and the control end of the second switch module are conductive. The base of the first switch tube Q1 and the energy storage module 10 are further connected in series with a resistor R11.

[0051] The second switch module 40 comprises a second switch tube Q2 and a third switch tube Q3. In the embodiment, the second switch tube Q2 is an NPN triode, and the third switch tube Q3 is a PMOS tube. The base of the second switch tube Q2 is connected with the first switch tube Q1, the emitter of the second switch tube Q2 is grounded, and the collector is connected with the gate of the third switch tube Q3. The source of the third switch tube Q3 is connected with the energy storage module 10, the drain of the third switch tube Q3 is connected with the execution assembly and the master control module 50, and the gate of the third switch tube Q3 and the collector of the second switch tube Q2 are connected with the energy storage module 10 through the first resistor R1.

[0052] When the first switch tube Q1 is closed, the energy storage module 10 inputs a high level to the base of the second switch tube Q2, the second switch tube Q2 is conductive, the gate voltage of the third switch tube Q3 is pulled down, the third switch tube Q3 is conductive, and thus the energy storage module 10 outputs a power supply Vin to supply power to the execution assembly and the master control module 10, and the master control module 50 completes initialization.

[0053] When the cover rotates beyond the preset angle, mechanical switch J2 is disconnected, the first switch Q1 is disconnected, and after the main control module 50 completes initialization, it continuously sends a high-level signal to the base of the second switch Q2 for a duration T, causing the second switch Q2 to conduct continuously, which in turn causes the third switch to conduct continuously. The energy storage module 10 continues to output power Vin to power the execution components and the main control module 50. After the duration T is reached (the flushing action is completed), the main control module 50 switches the control signal to send a low-level signal to the base of the second switch Q2, causing the second switch Q2 to disconnect. The gate voltage of the third switch Q3 is pulled high, causing the third switch Q3 to disconnect, the external power supply circuit of the energy storage module is disconnected, and the entire machine is powered off. It can be understood that the duration T can be set according to specific circumstances.

[0054] The third switching module 70 includes a fourth switching transistor Q4, which is an NPN transistor. The base of the fourth switching transistor Q4 is connected to the mains module 60, the emitter of the fourth switching transistor Q4 is grounded, and the collector is connected to the base of the second switching transistor Q2. When mains power is available, the base of the fourth switching transistor Q4 is at a high level, and the fourth switching transistor Q4 is turned on, pulling down the base voltage of the second switching transistor Q2. The second switching transistor Q2 remains in the off state when mains power is available. Even if the cover is closed, causing the first switching transistor Q1 to conduct and output a high level, the second switching transistor Q2 cannot be turned on, thus preventing the energy storage module 10 from supplying power to the outside when mains power is available.

[0055] See Figure 4 This embodiment provides a structure for triggering by a closed cover.

[0056] The trigger module includes a mechanical switch 1 linked to the cover's rotating shaft, a transmission component 2, a reset component 3, a rotating shaft 4, a driving component 5, a first spring sleeved on the transmission component 2, and a second spring sleeved on the reset component 3. The driving component 5 is directly or indirectly connected to the cover's rotating shaft; when the cover rotates, it drives the driving component 5 to rotate. When the cover is closed, the driving component 5 rotates clockwise, driving the rotating shaft 4 to rotate counterclockwise. The rotating shaft presses the transmission component 2 towards the mechanical switch 1, causing the transmission component 2 to contact the contacts of the mechanical switch 1, thus activating the mechanical switch 1. Continuing to rotate the cover, the driving component 5 flips over the upper end of the rotating shaft 4, the pressing force of the rotating shaft 4 towards the transmission component 2 disappears, and the transmission component 2 resets under the action of the first spring 6, disconnecting from the contacts of the mechanical switch 1. The mechanical switch 1 disengages, and the rotating shaft 4 also resets. This ensures that when the cover rotates to a certain angle range during the closing process, the mechanical switch 1 closes. Figure 3 Mechanical switch J2 is closed.

[0057] Similarly, if the cover is flipped, the driving member 5 is counterclockwise rotated, and the rotating shaft is rotated towards the direction away from the driving member 2, which does not affect the mechanical switch 1, and the rotating shaft 4 presses the reset member. When the rotating member 5 flips over the end of the rotating shaft 4, the second spring 7 restores the deformation, and the reset member 3 moves towards the rotating shaft 4, thereby resetting the rotating shaft 4. In the embodiment, the first spring 6 and the second spring 7 are compression springs.

[0058] In an embodiment, the closed lid flushing system further comprises a seat sensing assembly connected to the main control module. The seat sensing signal is detected by the main control module, and the seat is determined to be valid after a certain time T, and flushing is performed after the seat is left.

[0059] Alternatively, the closed lid flushing system further comprises a wireless module connected to the main control module. The flushing command is sent to the main control module by the remote control, and the main control module controls the execution assembly to execute flushing.

[0060] Alternatively, the closed lid flushing system further comprises a key assembly connected to the main control module. The flushing signal is sent to the main control module by pressing the key assembly.

[0061] Further, the closed lid flushing system comprises a foot sensing detection assembly connected to the main control module. The foot sensing detection assembly is used to detect the action or position of the human foot, for example, by emitting and receiving infrared rays to detect the presence and position of an object. When the user's foot enters the detection range of the sensor, the sensor will detect the reflected infrared signal, thereby determining the position of the user. For example, a pressure sensor is used to determine whether the user steps on a specified position by detecting the change in pressure applied thereto. When the user places his foot on the sensor, the sensor will detect the change in pressure and trigger the flushing function. In addition, ultrasonic sensors, magnetic induction sensors, pedals and other methods can be used to achieve foot sensing detection.

[0062] The embodiment also provides an intelligent toilet comprising the closed lid flushing system described above.

It should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments.
