The drive module includes a drive source connected to a first semiconductor element. The first switch module is used to conduct the circuit between the drive source and the first semiconductor element and a first consumable element, and a ground terminal. A first terminal of the first switch module is connected to the first consumable element, and a second terminal of the first switch module is grounded. The second switch module is used to control the circuit of the first switch module to cut off when power is available, allowing the drive source to drive the toilet seat normally.

Description

Technical Field

[0001] This application belongs to the field of smart toilet technology, and in particular relates to a smart toilet seat soft-close device. Background Technology

[0002] In existing smart toilet seat soft-close technology, motor-driven soft-close control circuits and protection circuits are widely used. When the power is off, the components connected to the motor of the smart toilet may fall rapidly due to factors such as gravity, thereby accelerating the damage to the device or posing a safety hazard.

[0003] Existing smart toilet seat soft-close technologies include two schemes. One scheme requires a power-on signal to cut off the MOSFET when the smart toilet is connected to mains power, ensuring the motor's speed control of the toilet seat / seat is not hindered when power is on. This design occupies one to two ports of the microcontroller, and the circuitry is relatively complex. The other scheme achieves a soft-close effect when the smart toilet is not connected to mains power. This scheme uses a diode connected in series with one end of the motor, passing through the MOSFET and returning to the other end of the motor to form a complete loop, creating a dynamic balance that prevents the toilet seat / seat from falling, thus allowing the toilet seat to descend slowly when power is off. However, this design requires the motor driver IC to support feedback and handle the current returning from the motor; otherwise, the IC may be damaged. It also requires more complex control logic to ensure correct energy feedback and prevent backflow problems. Therefore, this scheme places higher demands on the motor driver IC, requires more microcontroller pins, has a more complex circuit, and is more expensive. Utility Model Content

The first terminal of the second consumable element is connected to the positive terminal of the charging / discharging element, and the negative terminal of the charging / discharging element is grounded.

[0010] Optionally, the first switching module further includes a second semiconductor element connected to the positive terminal of the charging / discharging element, and the second semiconductor element is also connected to the first power source.

[0011] Optionally, the charging / discharging element is a polarized capacitor; and / or, the first consuming element, the second consuming element, and the third consuming element are all resistors; and / or, the second switching transistor is a MOSFET.

[0012] Optionally, the second switching module includes a first switching transistor, a first end of which is connected to a second power supply, a second end of which is connected to the second end of the second consumable element, the first end of the third consumable element, and the first end of the second switching transistor, respectively, and a third end of which is grounded.

[0013] Optionally, the first switching transistor is a bipolar transistor.

[0014] Secondly, one embodiment of this application provides a smart toilet seat soft-close device, comprising:

[0015] Multiple drive modules are provided, each drive module including a drive source for driving the toilet seat to lift or lower, the drive source being connected to a first semiconductor element; the first semiconductor element is also connected to a first consumable element, and the first consumable elements of two adjacent drive modules are interconnected.

[0016] A first switching module is used to turn on the circuit between the driving source and the first semiconductor element and the first consumable element and the ground terminal. The first terminal of the first switching module is connected to the first consumable element, and the second terminal of the first switching module is grounded.

[0017] The second switch module is used to control the circuit of the first switch module to be cut off when there is power, so that the drive source can drive the toilet seat to operate normally.

[0018] Optionally, the first switching module includes a charging / discharging element, a second consumable element, a third consumable element, and a second switching transistor. The third terminal of the second switching transistor is connected to the first consumable element. The second terminal of the second switching transistor and the second terminal of the third consumable element are both grounded. The first terminal of the second switching transistor is connected to the second terminal of the second consumable element and the first terminal of the third consumable element, respectively. The first terminal of the second consumable element is connected to the positive terminal of the charging / discharging element, and the negative terminal of the charging / discharging element is grounded.

[0019] Optionally, the first switching module further includes a second semiconductor element connected to the positive terminal of the charging / discharging element, and the second semiconductor element is also connected to the first power source.

[0020] Optionally, the second switching module includes a first switching transistor, a first end of which is connected to a second power supply, a second end of which is connected to the second end of the second consumable element, the first end of the third consumable element, and the first end of the second switching transistor, respectively, and a third end of which is grounded.

[0021] One embodiment of this application provides an intelligent toilet seat soft-close device, including a drive module, a first switch module, and a second switch module. The drive module includes a drive source for driving the toilet seat to open or close. The drive source is also connected to a first semiconductor element, which is also connected to a first consumable element. The first switch module is used to connect the drive source to the circuit between the first semiconductor element, the first consumable element, and a ground terminal. The first terminal of the first switch module is connected to the first consumable element, and the second terminal of the first switch module is grounded. The second switch module is used to control the circuit of the first switch module to close when there is power, allowing the drive source to drive the toilet seat normally. This intelligent toilet seat soft-close device, in the absence of mains power, uses a first switch module to conduct the current loop between the drive source and the ground terminal, hindering the toilet seat from falling and thus achieving the effect of slow descent when there is no mains power. A second switch module controls the circuit of the first switch module to be cut off, so the first switch module cannot conduct regardless of whether the toilet seat is opening or closing, thus not hindering speed control of the toilet seat when power is on. This intelligent toilet seat soft-close device has a simple circuit and low cost. It does not affect the normal opening and closing speed of the toilet seat when power is on, and also achieves a soft-close effect when there is no power, solving the problem of relatively complex and high-cost circuits in existing intelligent toilet seat soft-close technologies.

[0022] The circuit of this intelligent toilet seat soft-close device is relatively simple. When there is no power, the back electromotive force generated by the motor falling due to external force passes through the first semiconductor element, then through the first consumable element and the second switching transistor to the ground, forming a current loop. The current flowing through the motor causes the motor to generate an upward rotational force on the toilet seat, hindering its descent. The parameters of the first consumable element were selected through testing based on actual needs. This device not only achieves good soft-close and braking effects, but also protects the circuit components from damage caused by high back electromotive force, making the soft-close process more controllable. Furthermore, it can more effectively control the speed of the drive source and the falling speed when power is available. Moreover, the requirements for the drive chip IC are relatively low, resulting in a lower overall cost. Attached Figure Description

[0029] The technical solution of one embodiment of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] One embodiment of this application provides a smart toilet seat soft-close device to solve the problems of relatively complex circuits and high costs in existing smart toilet seat soft-close technologies. Example 1:

[0031] One embodiment of this application provides a smart toilet seat soft-close device; for example, please refer to [link to relevant documentation]. Figure 1 , Figure 1 A schematic diagram of the frame of a smart toilet seat soft-close device provided in one embodiment of this application. Figure 2 A circuit diagram of a smart toilet seat soft-close device provided in one embodiment of this application.

[0032] like Figure 1 and Figure 2 As shown, this utility model application provides an intelligent toilet seat soft-close device, including a drive module 10, a first switch module 20, and a second switch module 30.

[0033] like Figure 1 and Figure 2 As shown in the embodiment of the present utility model, the drive module 10 includes a drive source M, which is used to drive the toilet seat to lift or lower. The drive source M is also connected to a first semiconductor element D1; the first semiconductor element D1 is also connected to a first consumable element R1.

[0034] Furthermore, the driving source M can be a motor. The first consumable component R1 can be a resistor. The first semiconductor component D1 can be a diode. The toilet seat can be a toilet seat or a toilet rim. Figure 2 As shown, the driving module 10 also includes a driving chip U1 connected to the driving source M. Pin 8 of the driving chip U1 is connected to the anode of the first semiconductor element D1 and the first end of the driving source M, respectively. The cathode of the first semiconductor element D1 is connected to the first end of the first consumable element R1, and the second end of the first consumable element R1 is connected to the first switch module 20. Pin 6 of the driving chip U1 is connected to the second end of the driving source M. Pin 7 of the driving chip U1 is grounded. Pin 4 of the driving chip U1 is connected to the second power supply 2. In this embodiment, the driving chip U1 can be selected as a microcontroller or a microprocessor. The anode of the diode serves as the anode of the first semiconductor element D1, and the cathode of the diode serves as the cathode of the first semiconductor element D1.

[0035] like Figure 1 and Figure 2As shown in the embodiment of this utility model, the function of the first consumable element R1 is to control the magnitude of the loop current formed by the drive source M1, the first switch module 20, and the ground terminal. If the first consumable element R1 is too small, the current will be too large, and the rotation force of the drive source M1 will increase, generating a force that hinders the toilet seat from falling, resulting in a very slow descent or even failure to fall. If the first consumable element R1 is too large, the current will be too small, and the reverse current flowing through the drive source M1 will be very small, resulting in a very weak reverse rotation force, which is equivalent to almost no resistance, and thus no slow-descent effect. Therefore, the resistance and power parameters of the first consumable element R1 should be tested and selected according to actual needs.

[0036] like Figure 1 and Figure 2 As shown in the embodiment of the present utility model, the first switch module 20 is used to conduct the circuit between the first semiconductor element D1 and the first consumable element R1 and the ground terminal when there is no power. The first terminal of the first switch module 20 is connected to the first consumable element R1, and the second terminal of the first switch module 20 is grounded.

[0037] To further clarify, the first terminal of the first switch module 20 is connected to the second terminal of the first consumable element R1. When the smart toilet is without mains power (also known as without mains power), during the descent of the toilet seat, the drive source M1 of the smart toilet seat soft-close device switches to generator mode, generating a reverse electromotive force. The first semiconductor element D1 is forward-biased, the circuit of the first switch module 20 is turned on, and the current from the drive source M1 flows through the first switch module D1, then through the first consumable element R1, and then through the first switch module 20 to ground, forming a current loop. The current in this current loop flows through the drive source M1, causing the drive source M1 to generate an upward rotational force (the greater the current, the greater the rotational force), which hinders the descent of the toilet seat, thus achieving the effect of the toilet seat slowly descending when there is no mains power. Conversely, when the toilet seat is flipped up, the drive source M1 is in generator mode, and the first semiconductor element D1 is reverse-biased and not conducting, so it does not hinder the flipping up of the toilet seat when the power is off.

[0038] like Figure 1 and Figure 2 As shown in the embodiment of the present utility model, the second switch module 30 is used to control the circuit of the first switch module 20 to be cut off when there is power, so that the drive source M1 can drive the toilet seat to run normally.

[0039] To further explain, when the smart toilet is powered by mains electricity (also known as having mains power), the smart toilet seat soft-close device controls the circuit of the first switch module 20 to be cut off through the second switch module 30. The first switch module 20 cannot be turned on regardless of whether the toilet seat is flipped up or down, so it will not hinder the speed control of the toilet seat when powered on.

[0040] In the embodiments of this utility model, the intelligent toilet seat soft-close device does not affect the smooth upward and downward speed of the toilet seat when powered on, and also achieves a soft-close effect when there is no power. This intelligent toilet seat soft-close device eliminates the need for the pin ports of the driver chip U1 to control the operation of the first switch module 20 and the second switch module 30, reducing the occupation of the driver chip U1 pin ports and lowering the requirements for the driver chip IC, thus reducing costs.

[0041] An embodiment of this application provides an intelligent toilet seat soft-close device, including a drive module, a first switch module, and a second switch module. The drive module includes a drive source for driving the toilet seat to open or close. The drive source is also connected to a first semiconductor element. The first semiconductor element is also connected to a first consumable element. The first switch module is used to connect the circuit between the drive source, the first semiconductor element, the first consumable element, and a ground terminal. The first terminal of the first switch module is connected to the first consumable element, and the second terminal of the first switch module is grounded. The second switch module is used to control the circuit of the first switch module to close when there is power, so that the drive source can normally drive the toilet seat to operate. This intelligent toilet seat soft-close device, in the absence of mains power, uses a first switch module to conduct the current loop between the drive source and the ground terminal, hindering the toilet seat from falling and thus achieving the effect of slow descent when there is no mains power. A second switch module controls the circuit of the first switch module to be cut off, so the first switch module cannot conduct regardless of whether the toilet seat is opening or closing, thus not hindering speed control of the toilet seat when power is on. This intelligent toilet seat soft-close device has a simple circuit and low cost. It does not affect the normal opening and closing speed of the toilet seat when power is on, and also achieves a soft-close effect when there is no power, solving the problem of relatively complex and high-cost circuits in existing intelligent toilet seat soft-close technologies.

[0042] To further explain, the circuit of this intelligent toilet seat soft-close device is relatively simple. When there is no power, the back electromotive force generated by the motor falling due to external force passes through a first semiconductor element, then through a second switching transistor (a first consumable component) to ground. This current loop causes the current flowing through the motor to generate an upward rotational force on the toilet seat, hindering its descent. The parameters of the first consumable component were selected through testing based on actual needs. This device not only achieves good soft-close and braking effects but also protects circuit components from damage caused by high back electromotive force, making the soft-close process more controllable. Furthermore, it can more effectively control the speed of the drive source and the falling speed when power is available. Moreover, the requirements for the drive chip IC are relatively low, resulting in a lower overall cost.

[0043] like Figure 2As shown, in one embodiment of this utility model, the first switch module 20 includes a charging / discharging element C1, a second consumable element R2, a third consumable element R3, and a second switch transistor U2. The third terminal of the second switch transistor U2 is connected to the first consumable element R1. The second terminals of both the second switch transistor U2 and the third consumable element R3 are grounded. The first terminal of the second switch transistor U2 is connected to the second terminals of both the second and third consumable elements R2 and R3. The first terminal of the second consumable element R2 is connected to the positive terminal of the charging / discharging element C1, and the negative terminal of the charging / discharging element C1 is grounded. The first switch module 20 also includes a second semiconductor element D2 connected to the positive terminal of the charging / discharging element C1, and the second semiconductor element D2 is also connected to the first power supply 1.

[0044] Furthermore, the charging / discharging element C1 can be selected as a polarized capacitor; the second and third consumable elements R2 and R3 can both be selected as resistors; and the second switching transistor U2 can be selected as a MOSFET. The third terminal of the second switching transistor U2 serves as the first terminal of the first switching module 20, and the second terminal of the second switching transistor U2 serves as the second terminal of the first switching module 20. The working principle of the first switching module is as follows: when there is no mains power, during the descent of the toilet seat, the driving source M1 switches to generator mode, generating a reverse electromotive force, and the first semiconductor element D1 is forward-biased, such as... Figure 2 As shown, when power is off, the charging / discharging element C1 discharges, the second switch U2 is in the conducting state, and the current from the driving source M1 flows through the first semiconductor element D1, then through the first consumable element R1, and then through the second switch U2 to the ground terminal, forming a current loop to slow down the speed at which the driving source M drives the toilet seat to descend. During the descent of the toilet seat, the current flows through the driving source M1, causing it to generate an upward rotational force (the greater the current, the greater the rotational force), which hinders the descent of the toilet seat, thus achieving the effect of the toilet seat descending slowly when there is no mains power. Conversely, when the toilet seat is flipped up, the driving source M1 is in generator mode, the first semiconductor element D1 is reverse cut off and not conducting, so it does not hinder the flipping up of the toilet seat when power is off. In this embodiment, the gate of the MOSFET is used as the first terminal of the second switch U2. The first power supply 1 can be selected as a 5V DC power supply.

[0045] like Figure 2 As shown, in one embodiment of the present invention, the second switch module 30 includes a first switch transistor Q1. The first end of the first switch transistor Q1 is connected to the second power supply 2. The second end of the first switch transistor Q1 is connected to the second end of the second consumable element R2, the first end of the third consumable element R3, and the first end of the second switch transistor Q1, respectively. The third end of the first switch transistor Q1 is grounded.

[0046] To further clarify, the first switching transistor Q1 can be selected as a transistor, with its base serving as the first terminal, its collector as the second terminal, and its emitter as the third terminal. The second power supply 2 can be a 3.3V or 5V DC power supply. The working principle of the second switching module 30 is as follows: when there is mains power, such as... Figure 2 The second power supply 2 pulls the first terminal of the first switch tube Q1 high, so the first switch tube Q1 conducts and the voltage at the first terminal of the second switch tube U2 is pulled low. This means that when the power is on, the second switch tube U2 cannot conduct regardless of whether the toilet seat is flipped up or down, so it will not hinder the speed control of the toilet seat when the power is on. Example 2:

[0047] Another embodiment of this application provides a smart toilet seat soft-close device, exemplified by [example provided]. Figure 3 , Figure 3 A schematic diagram of the frame of a smart toilet seat soft-close device provided for another embodiment of this application. Figure 4 A circuit diagram of a smart toilet seat soft-close device provided for another embodiment of this application.

[0048] like Figure 3 and Figure 4 As shown, this utility model application provides an intelligent toilet seat soft-close device, including multiple drive modules 10, a first switch module 20, and a second switch module 30.

[0049] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, each drive module 10 includes a drive source M, which is used to drive the toilet seat to lift or lower. The drive source M is also connected to a first semiconductor element D1. The first semiconductor element D1 is also connected to a first consumable element R1, and the first consumable elements R1 of two adjacent drive modules 10 are connected to each other.

[0050] Furthermore, the driving source M can be a motor. The first consumable component R1 can be a resistor. The first semiconductor component D1 can be a diode. The toilet seat can be a toilet seat or a toilet rim. Figure 2As shown, the driving module 10 also includes a driving chip U1 connected to the driving source M. Pin 8 of the driving chip U1 is connected to the anode of the first semiconductor element D1 and the first end of the driving source M, respectively. The cathode of the first semiconductor element D1 is connected to the first end of the first consumable element R1. The second end of the first consumable element R1 is connected to the first switch module 20. Pin 6 of the driving chip U1 is connected to the second end of the driving source M. Pin 7 of the driving chip U1 is grounded. Pin 4 of the driving chip U1 is connected to the second power supply 2. In this embodiment, the driving chip U1 can be selected as a microcontroller or a microprocessor. The anode of the diode serves as the anode of the first semiconductor element D1, and the cathode of the diode serves as the cathode of the first semiconductor element D1. The first consumable elements of two adjacent driving modules 10 are denoted as R1 and R11, respectively. The second end of the first consumable element R1 is connected to the second end of the first consumable element R11.

[0051] like Figure 3 and Figure 4 As shown, in an embodiment of the present utility model, the first switch module 20 is used to connect the circuit between the first semiconductor element D1 and the first consumable element R1 of the driving source M and the ground terminal. The first end of the first switch module 20 is connected to the first consumable element R1, and the second end of the first switch module 20 is grounded.

[0052] To further clarify, the first terminal of the first switch module 20 is connected to the second terminal of the first consumable element R1. When the smart toilet is without mains power (also known as without mains power), during the descent of the toilet seat, the drive source M1 of the smart toilet seat soft-close device switches to generator mode, generating a reverse electromotive force. The first semiconductor element D1 is forward-biased, the circuit of the first switch module 20 is turned on, and the current from the drive source M1 flows through the first switch module D1, then through the first consumable element R1, and then through the first switch module 20 to the ground terminal, forming a current loop. The current in this current loop flows through the drive source M1, causing the drive source M1 to generate an upward rotational force (the greater the current, the greater the rotational force, so the first consumable element R1 needs to be selected appropriately) to hinder the descent of the toilet seat, thereby achieving the effect of the toilet seat descending slowly when there is no mains power. Conversely, when the toilet seat is flipped up, the drive source M1 is in generator mode, the first semiconductor element D1 is reverse-biased and not conducting, so it will not hinder the flipping up of the toilet seat when the power is off.

[0053] like Figure 3 and Figure 4 As shown in the embodiment of the present utility model, the second switch module 30 is used to control the circuit of the first switch module 20 to be cut off when there is power, so that the drive source M can drive the toilet seat to operate normally.

[0054] To further explain, when the smart toilet is powered by mains electricity (also known as having mains power), the smart toilet seat soft-close device controls the circuit of the first switch module 20 to be cut off through the second switch module 30. The first switch module 20 cannot be turned on regardless of whether the toilet seat is flipped up or down, so it will not hinder the speed control of the toilet seat when powered on.

[0055] In the embodiments of this utility model, the intelligent toilet seat soft-close device does not affect the smooth upward and downward speed of the toilet seat when powered on, and also achieves a soft-close effect when there is no power. This intelligent toilet seat soft-close device eliminates the need for the pin ports of the driver chip U1 to control the operation of the first switch module 20 and the second switch module 30, reducing the occupation of the driver chip U1 pin ports and lowering the requirements for the driver chip IC, thus reducing costs.

[0056] like Figure 4 As shown, in one embodiment of this utility model, the first switch module 20 includes a charging / discharging element C1, a second consumable element R2, a third consumable element R3, and a second switch transistor U2. The third terminal of the second switch transistor U2 is connected to the first consumable element R1. The second terminals of both the second switch transistor U2 and the third consumable element R3 are grounded. The first terminal of the second switch transistor U2 is connected to the second terminals of both the second and third consumable elements R2 and R3. The first terminal of the second consumable element R2 is connected to the positive terminal of the charging / discharging element C1, and the negative terminal of the charging / discharging element C1 is grounded. The first switch module 20 also includes a second semiconductor element D2 connected to the positive terminal of the charging / discharging element C1, and the second semiconductor element D2 is also connected to the first power supply 1.

[0057] Furthermore, the charging / discharging element C1 can be selected as a polarized capacitor; the second and third consumable elements R2 and R3 can both be selected as resistors; and the second switching transistor U2 can be selected as a MOSFET. The third terminal of the second switching transistor U2 serves as the first terminal of the first switching module 20, and the second terminal of the second switching transistor U2 serves as the second terminal of the first switching module 20. The working principle of the first switching module is as follows: when there is no mains power, during the descent of the toilet seat, the driving source M1 switches to generator mode, generating a reverse electromotive force, and the first semiconductor element D1 is forward-biased, such as... Figure 2As shown, when power is off, the charging / discharging element C1 discharges, the second switch U2 is in the conducting state, and the current from the driving source M1 flows through the first semiconductor element D1, then through the first consumable element R1, and then through the second switch U2 to ground, forming a current loop. The current in this loop flows through the driving source M1, causing it to generate an upward rotational force (the greater the current, the greater the rotational force), hindering the toilet seat from falling, thus achieving the effect of the toilet seat slowly lowering when there is no mains power. Conversely, when the toilet seat is flipped up, the driving source M1 is in generator mode, and the first semiconductor element D1 is reverse-biased and not conducting, so it does not hinder the toilet seat from flipping up when power is off. In this embodiment, the gate of the MOSFET serves as the first terminal of the second switch U2. The first power supply 1 can be selected as a 5V DC power supply.

[0058] like Figure 4 As shown, in one embodiment of the present invention, the second switch module 30 includes a first switch transistor Q1. The first end of the first switch transistor Q1 is connected to the second power supply 2. The second end of the first switch transistor Q1 is connected to the second end of the second consumable element R2, the first end of the third consumable element R3, and the first end of the second switch transistor Q1, respectively. The third end of the first switch transistor Q1 is grounded.

[0059] To further clarify, the first switching transistor Q1 can be selected as a transistor, with its base serving as the first terminal, its collector as the second terminal, and its emitter as the third terminal. The second power supply 2 can be a 3.3V or 5V DC power supply. The working principle of the second switching module 30 is as follows: when there is mains power, such as... Figure 2 The second power supply 2 pulls the first terminal of the first switch tube Q1 high, so the first switch tube Q1 conducts and the voltage at the first terminal of the second switch tube U2 is pulled low. This means that when the power is on, the second switch tube U2 cannot conduct regardless of whether the toilet seat is flipped up or down, so it will not hinder the speed control of the toilet seat when the power is on.

[0060] In this utility model application, the intelligent toilet seat slow-closing device of Embodiment 2 has the same basic technical solution as the intelligent toilet seat slow-closing device of Embodiment 1. The difference is that the intelligent toilet seat slow-closing device of Embodiment 2 can control multiple toilet seats at the same time.

[0061] To further clarify, if the toilet involves controlling multiple drive sources, such as the toilet seat having two or more drive sources, then...
