Description

Technical Field

[0001] This utility model relates to the field of circuit control, specifically to a photoelectric tilt switch circuit. Background Technology

[0002] The TDP therapy device uses a specific heater to heat a TDP radiation plate, generating specific electromagnetic waves distributed within a wavelength range of 2-25μm and an intensity range of 25-35mw / capacitance Cm2. These waves are then absorbed, transmitted, transformed, and utilized by the body, which matches the absorption spectrum of human cells, producing biological effects. These effects include enhancing microcirculation, promoting metabolism, adjusting the state of trace elements, ion concentration, and cellular levels in the body, promoting biological information metabolism, repairing human diseases, and improving the body's immunity.

[0003] However, in actual use, the existing TDP therapy device is too long and has an unstable center of gravity, making it prone to tipping over during use. If the power is not turned off when it tipps over, it can easily cause damage to electrical appliances and cause the surrounding environment to catch fire due to heat. Utility Model Content

[0004] The purpose of this invention is to provide a photoelectric tilt switch circuit to solve the problem that failure to disconnect power during tilting can easily cause damage to electrical appliances and cause the surrounding environment to catch fire due to heat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photoelectric tilt switch circuit, comprising:

[0006] Photoelectric switch module: includes photoelectric switch housing, photosensitive device, light source, 45° truncated cone and steel ball. The photoelectric switch housing is a cylindrical cavity with the light source at the bottom and the photosensitive device at the top. The 45° truncated cone is located on top of the light source and limits the steel ball so that the steel ball blocks the light path between the light source and the photosensitive device. When the photoelectric switch housing is tilted at 45°, the steel ball no longer blocks the light path between the light source and the photosensitive device, that is, the photoelectric switch is triggered at this time.

[0007] Power module: includes resistor R3, resistor R4, capacitor C1, polarized capacitor C2, Zener diode D3 and diode D4, so that resistor R3, resistor R4, capacitor C1, polarized capacitor C2, Zener diode D3 and diode D4 form a voltage regulator circuit and provide a stable DC power supply for the entire circuit.

[0008] Control module: Includes microcontroller, transistor Q1 and bidirectional thyristor Q2. Based on the response signal of the photoelectric switch module, the microcontroller controls the switching state of the bidirectional thyristor Q2 to achieve power failure protection.

[0009] Preferably, the 45° frustum is a hollow structure.

[0010] Preferably, the photosensitive device is electrically connected to the microcontroller and transmits a light source signal to the microcontroller so that the microcontroller can control the switching state of the bidirectional thyristor Q2.

[0011] Preferably, resistors R3 and R4 are used to limit current and protect the entire circuit, while capacitors C1 and C2 are used to filter and stabilize voltage, ensuring stable circuit operation.

[0012] Preferably, the Zener diode D3 and diode D4 serve a protective function throughout the circuit.

[0013] Preferably, the circuit also includes a status indicator module, which includes diode D1, resistor R1, LED1, diode D2, resistor R2, and LED2, for indicating the operating status of the circuit.

[0014] Preferably, the circuit also includes a protection module, which includes fuses F1 and F2 for overcurrent protection of the entire circuit. When the current in the circuit exceeds the rated value, the fuses blow to cut off the circuit and prevent damage.

[0015] Preferably, the power supply module further includes resistors R5, R6, R7, and R8 for voltage division to provide a stable voltage to the photoelectric switch module.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the tilt angle of the photoelectric switch housing is greater than 45°, the steel ball no longer blocks the light source emitted by the light source. At this time, the photosensitive device receives the light signal from the light source and its resistance changes. Simultaneously, the microcontroller controls the bidirectional thyristor Q2 to break the circuit based on the resistance change of the photosensitive device, thereby preventing the TDP therapy device from working after being tilted, thus avoiding damage to the TDP therapy device or the burning of other items due to baking.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a photoelectric tilt switch circuit, comprising:

[0024] The photoelectric switch module includes a photoelectric switch housing 1, a photosensitive device 2, a light source 3, a 45° truncated cone 4, and a steel ball 5. The light source 3 and the photosensitive device 2 are located at the bottom and top of the photoelectric switch housing 1, respectively. The 45° truncated cone 4 is set on top of the light source 3 and limits the steel ball 5 so that the steel ball 5 blocks the light path between the light source 3 and the photosensitive device 2. When the photoelectric switch housing 1 is tilted at 45°, the steel ball 5 no longer blocks the light path between the light source 3 and the photosensitive device 2, that is, the photoelectric switch is triggered at this time. The 45° truncated cone 4 is a hollow structure so that the steel ball 5 can move within the 45° truncated cone 4.

[0025] The power supply module includes resistors R3 and R4, capacitor C1, polarized capacitor C2, Zener diode D3, and diode D4. These components form a regulated power supply circuit to provide a stable DC power supply for the entire circuit. The power supply module also includes resistors R5, R6, R7, and R8 for voltage division to provide a stable voltage to the photoelectric switch module. Resistors R3 and R4 limit current and protect the entire circuit. Capacitors C1 and C2 filter and stabilize the voltage to ensure stable circuit operation. Zener diodes D3 and D4 provide protection throughout the circuit.

[0026] The control module includes a microcontroller, transistor Q1, and bidirectional thyristor Q2. Based on the response signal from the photoelectric switch module, the microcontroller controls the switching state of the bidirectional thyristor Q2 to achieve power-off protection. Photosensitive device 2 is electrically connected to the microcontroller and transmits optical signals to it, enabling the microcontroller to control the switching state of the bidirectional thyristor Q2. Figure 1 As shown, the circuit input also includes fuses F1 and F2 for circuit protection.

[0027] It also includes a status indicator module, which includes diode D1, resistor R1, LED1, diode D2, resistor R2 and LED2, used to indicate the operating status of the circuit.

[0028] It also includes a protection module, which includes fuses F1 and F2 for overcurrent protection of the entire circuit. When the current in the circuit exceeds the rated value, the fuses melt and disconnect the circuit to prevent damage. Diode D1, resistor R1, and LED1 are connected in series; diode D2, resistor R2, and LED2 are connected in series; and the series combination of diode D1, resistor R1, and LED1 is connected in parallel with the series combination of diode D2, resistor R2, and LED2 to detect the circuit's operating status. Resistors R3 and R4 are connected in series and in parallel with the status indicator module. Diodes D3 and D4 are connected in parallel to the output of resistor R4. Resistors R5 and R6, along with polarized capacitor C2 and transistor Q1, are connected in parallel to the output of diode D4. The photoelectric switch module is connected to the outputs of resistors R5 and R6 and transistor Q1. The input of bidirectional thyristor Q2 is electrically connected to resistors R8 and R7, respectively. The output of bidirectional thyristor Q2 is connected to the series circuit containing diode D2, resistor R2, and LED2. Once the microcontroller controls bidirectional thyristor Q2 to be in the off state, the entire circuit is disconnected.

[0029] Working Principle: When the TDP therapy device is in use, the steel ball 5 is positioned in the middle of the 45° frustum 4, completely blocking the light emitted by the light source 3. When the TDP therapy device is tilted, it will cause the photoelectric switch housing 1 to tilt as well, allowing the steel ball 5 to move within the 45° frustum 4. When the tilt angle of the photoelectric switch housing 1 is greater than 45°, the steel ball 5 moves to one side of the inner wall of the 45° frustum 4 and no longer blocks the light emitted by the light source 3. At this time, the photosensitive device 2 receives the light signal from the light source 3 and its resistance changes. Simultaneously, it transmits the changed resistance information to the microcontroller. The microcontroller controls the bidirectional thyristor Q2 to break the circuit based on the resistance change of the photosensitive device 3, thus preventing the TDP therapy device from working after tilting and avoiding damage to the TDP therapy device or the burning of other items due to heating.
