[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0024] See also Figure 1 , Figure 1 The specific structure of the energy recovery toilet of the utility model is shown, which includes a toilet body, a kinetic energy conversion circuit 1, a battery pack 2, a DC power supply circuit 3, a power supply circuit 4, an Internet of Things power supply interface 5, and an Internet of Things module 6. The kinetic energy conversion circuit 1, the battery pack 2, the DC power supply circuit 3, the power supply circuit 4, the Internet of Things power supply interface 5, and the Internet of Things module 6 are respectively arranged on the toilet body;

[0025] The kinetic energy conversion circuit 1 is connected to the battery pack 2. The kinetic energy conversion circuit 1 is used to convert the mechanical energy generated by the toilet body into electrical energy and output the electrical energy to the battery pack 2 for storage;

[0026] The battery pack 2 is connected to the power circuit 4 and is used to provide internal power to the power circuit 4;

[0027] The DC power supply circuit 3 is connected to the power supply circuit 4 and is used to provide external power to the power supply circuit 4;

[0028] The power supply circuit 4 is connected to the Internet of Things module 6 through the Internet of Things power supply interface 5 and is used to supply power to the Internet of Things module 6.

[0029] When the user uses the energy recovery toilet, the toilet body vibrates and generates mechanical energy. At this time, the kinetic energy conversion circuit 1 can convert the mechanical energy generated by the toilet body into electrical energy, and output the electrical energy to the battery pack 2 for storage, thereby achieving the purpose of mechanical energy recovery; when the external power supply is normally powered, power can be supplied to the power supply circuit 4 through the DC power supply circuit 3, and then power can be supplied to the Internet of Things module 6 through the Internet of Things power supply interface 5 to ensure the normal use of the Internet of Things module 6; when the external power supply fails / disconnected, power can be supplied to the power supply circuit 4 through the battery pack 2, and then power can be supplied to the Internet of Things module 6 through the Internet of Things power supply interface 5 to ensure the normal use of the Internet of Things module 6.

[0030] Therefore, the utility model can effectively recycle the mechanical energy generated by the daily use of the toilet, thereby ensuring that the Internet of Things module 6 can be used normally even when the external power supply of the toilet is cut off, thereby improving the user experience.

[0031] like Figure 2 As shown, the kinetic energy conversion circuit 1 includes a detection module PZT, a first voltage-dividing resistor R32, a second voltage-dividing resistor R30, a third voltage-dividing resistor R42, a fourth voltage-dividing resistor R31 and a voltage-dividing capacitor C4; wherein, one end of the detection module PZT is connected to the battery pack 2, and the other end is grounded; one end of the first voltage-dividing resistor R32 is connected to the battery pack 2, and the other end is connected to the power supply circuit 4; one end of the second voltage-dividing resistor R30 is connected to the DC power supply circuit 3, and the other end is connected to the power supply circuit 4; one end of the third voltage-dividing resistor R42, the fourth voltage-dividing resistor R31 and the voltage-dividing capacitor C4 are respectively grounded, and the other ends are respectively connected to the power supply circuit 4.

[0032] Therefore, the electrical energy generated by the detection module PZT can be stored in the battery pack 2 through the kinetic energy conversion circuit 1. At the same time, the current output by the battery pack 2 and the DC power supply circuit 3 can be stably output to the power supply circuit 4 after being divided by the voltage-dividing elements (the first voltage-dividing resistor R32, the second voltage-dividing resistor R30, the third voltage-dividing resistor R42, the fourth voltage-dividing resistor R31 and the voltage-dividing capacitor C4).

[0033] Furthermore, the detection module PZT can be piezoelectric ceramics and / or flexible ceramics; wherein, the piezoelectric ceramics can be arranged at the connection between the bottom of the toilet body and the ground, and can effectively absorb the mechanical energy generated by the toilet body when the toilet is in use or when the floor moves slightly; and the flexible ceramics can be arranged on the seat ring of the toilet body, which can more directly absorb the mechanical energy generated when the user sits on the seat ring, and realize the effective conversion of mechanical energy and electrical energy.

[0034] It should be noted that piezoelectric ceramics are a type of information-functional ceramic material capable of converting mechanical energy into electrical energy. Piezoelectric ceramics utilize the relative displacement of internal positive and negative charge centers under mechanical stress, causing polarization. This results in bound charges of opposite signs on the surfaces of the material (i.e., the piezoelectric effect), thereby achieving the conversion of mechanical and electrical energy. Flexible ceramics also exhibit this piezoelectric effect, and their internal laminated structure effectively absorbs and disperses impact forces, facilitating their use in seat rings.

[0035] Accordingly, the DC power supply circuit 3 in the present invention can adopt an existing transformer circuit, which will not be described in detail here, as long as it can convert 220V AC mains power into 12V DC power; in addition, the Internet of Things power supply interface 5 can be a DC interface, but is not limited to this, as long as stable transmission of voltage and current can be achieved; at the same time, the Internet of Things module 6 can be a BL602 module, but is not limited to this, as long as the Internet of Things function can be achieved.

[0036] like Figure 3As shown, the power supply circuit 4 includes a detection circuit, a switching circuit 42, and a main control chip. The switching circuit 42 is connected to the detection circuit and the main control chip respectively. The detection circuit is used to obtain control signals. The switching circuit 42 is connected to the battery pack 2 to form a battery power supply circuit, and is connected to the DC power supply circuit 3 to form a DC power supply circuit. The switching circuit 42 controls the on / off status of the battery power supply circuit and the DC power supply circuit according to the control signal and feedbacks the on / off status to the main control chip. The main control chip is preferably the Renesas R5F110FE chip, but this is not a limitation and can be selected according to actual conditions.

[0037] When the external power supply is supplying power normally, the switching circuit 42 controls the battery power supply circuit to be disconnected and controls the conduction of the DC power supply circuit, thereby supplying power to the power supply circuit 4 through the DC power supply circuit 3; when the external power supply fails / is disconnected, the switching circuit 42 controls the conduction of the battery power supply circuit and controls the shutdown of the DC power supply circuit, thereby supplying power to the power supply circuit 4 through the battery pack 2, and then supplying power to the Internet of Things module 6 through the Internet of Things power supply interface 5 to ensure the normal use of the Internet of Things module 6.

[0038] During use, the user can turn off / on the battery power supply function according to actual needs; after turning off the battery power supply function, regardless of whether the DC power supply circuit 3 is supplying power normally, the power supply circuit 4 cannot be supplied by the battery pack 2; after turning on the battery power supply function, the power supply circuit 4 can control the DC power supply circuit 3 or the battery pack 2 to supply power to the power supply circuit 4 according to the detected current state of the DC power supply circuit 3.

[0039] Accordingly, the detection circuit includes a switch detection circuit 412 and / or a current detection circuit 411. The switch detection circuit 412 is used to detect the external switch state to generate a switch control signal. The current detection circuit 411 is used to detect the current state of the DC power supply circuit 3 to generate a detection control signal.

[0040] It should be noted that the user can control the switching state of the battery power supply function through an external switch, so that the switch detection circuit 412 generates a corresponding switch control signal; at the same time, the current detection circuit 411 detects the current state of the DC power supply circuit 3 in real time to generate a corresponding detection control signal.

[0041] The switching circuit 42, the switch detection circuit 412 and the current detection circuit 411 are described in detail below in conjunction with the specific circuit diagrams:

The collector of the first transistor Q3 is connected to the main control chip via the second resistor R2 and the third resistor R3, respectively. The base of the first transistor Q3 is connected to the DC power supply circuit 3 via the fourth resistor R4 and to ground via the fifth resistor R5. The emitter of the first transistor Q3 is grounded. One end of the first resistor R1 is connected to the collector of the first transistor Q3, and the other end is connected to the DC power supply circuit 3 via the first diode D1 and to the battery pack 2 via the diode group D. The source of the first switch Q1 is connected to the main control chip, the drain of the first switch Q1 is connected to the detection circuit, and the gate of the first switch Q1 is connected between the second resistor R2 and the third resistor R3.

[0044] When the current detection circuit 411 detects that the DC power supply circuit 3 is normal, the DC power supply circuit is turned on by the first switch tube Q1 and the first transistor Q3, so as to supply power to the power supply circuit 4 through the DC power supply circuit 3. When the switch detection circuit 412 detects that the battery power supply function is turned on and the current detection circuit 411 detects that the DC power supply circuit 3 is abnormal, the battery power supply circuit is turned on by the first switch tube Q1 and the first transistor Q3, so as to supply power to the power supply circuit 4 through the battery pack 2.

[0045] 2. Switch Detection Circuit 412

[0046] The switch detection circuit 412 includes a second transistor Q4, a sixth resistor R6, and a seventh resistor R7. The emitter of the second transistor Q4 is grounded. The base of the second transistor Q4 is connected to the external switch through the sixth resistor R6 and to ground through the seventh resistor R7. The base and collector of the second transistor Q4 are connected to the switching circuit 42.

[0047] When the external switch outputs an ON signal to the switch detection circuit 412 , the second transistor Q4 is turned on; when the external switch outputs an OFF signal to the switch detection circuit 412 , the second transistor Q4 is turned off, thereby generating different switch control signals.

[0048] 3. Current Detection Circuit 411

[0049] The current detection circuit 411 includes a second diode D2, a third diode D3, a first capacitor C1, a second capacitor C2, a third capacitor C3, a polarity capacitor EC1, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, and a second switching transistor Q2. The source of the second switching transistor Q2 is connected to the battery pack 2, the drain of the second switching transistor Q2 is connected to the DC power supply circuit 3 via the second diode D2, the gate of the second switching transistor Q2 is connected to the cathode of the third diode D3, the anode of the third diode D3 is connected to the switching circuit 42 via the tenth resistor R10 and to ground via the third capacitor C3, and the third diode D3 is connected in parallel with the eighth resistor R8. One end of the first capacitor C1 is connected to the battery pack 2, and the other end is connected to the cathode of the third diode D3. One end of the second capacitor C2 is connected to the drain of the second switching transistor Q2, and the other end is connected to the cathode of the third diode D3. One end of the ninth resistor R9 is connected to the battery pack 2, and the other end is connected to the anode of the third diode D3. The positive electrode of the polarity capacitor EC1 is connected to the DC power supply circuit 3, and the negative electrode is grounded.

[0050] When the DC power supply circuit 3 is normal, the second switch tube Q2 is disconnected, and power can be supplied to the switching circuit 42 through the DC power supply circuit 3; when the DC power supply circuit 3 is abnormal, the second switch tube Q2 is turned on, and power can be supplied to the switching circuit 42 through the battery pack 2.

[0051] As can be seen from the above, the present invention realizes flexible switching of the DC power supply circuit 3 and the battery power supply circuit by providing the first switch tube Q1, the first transistor Q3, the second transistor Q4 and the second switch tube Q2, thereby achieving the purpose of kinetic energy recovery and extending the battery life after power failure.

[0052] See also Figure 4 , Figure 4 The specific structure of the energy recovery system 100 of the present invention is shown, which includes a terminal 101 and an energy recovery toilet 102. The terminal 101 and the energy recovery toilet 102 are connected via the Internet of Things.

[0053] Therefore, through the present invention, in the event of an external power failure / power outage, the circuit stored in the battery pack 2 can still maintain the normal operation of the toilet for a period of time, and push reminders to the user, allowing the user to understand the status of the toilet in a timely manner.

[0054] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
