Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In related technologies, as society develops and people's demands for living comfort increase, their requirements for the user experience of heating products also become higher. Taking electric blankets as an example, traditional electric blanket controllers are generally controlled by 220V AC power. However, for products that need to come into direct contact with the human body, the 220V output poses a significant risk, potentially causing electric shock to users.

[0020] In view of this, this application provides a low-pressure temperature control device. Figure 1 This is a schematic diagram of the structure of a low-pressure temperature control device provided in an embodiment of this application. Figure 1 The low-pressure temperature control device may include, but is not limited to: The system includes an MCU control module 100, a first heating module 200, and a second heating module 300. The MCU control module 100 is connected to the first heating module 200 and the second heating module 300 respectively, and controls the first heating module 200 and the second heating module 300. The first heating module 200 and the second heating module 300 are respectively located in different areas and configured to heat different areas at different temperatures. The first heating module 200 includes a first output control unit 210, and the second heating module 300 includes a second output control unit 310. The first output control unit 210 is used to control the first heating temperature of the first heating module 200, and the second output control unit 310 is used to control the second heating temperature of the second heating module 300. The output voltage of both the first output control unit 210 and the second output control unit 310 is not greater than 36V.

[0021] Specifically, an MCU (Microcontroller Unit) control module is a small computer system that integrates a processor core, memory, input / output interfaces, and peripheral functional modules, and can be applied to embedded systems. In this embodiment, the MCU control module 100 undertakes the most important control tasks, such as regulating the heating temperature and controlling the functions of other modules.

[0022] On the other hand, it also includes a first heating module 200 and a second heating module 300. These two modules operate independently and can heat different areas at different temperatures. For an electric blanket, this is equivalent to dividing the entire blanket into two heating zones, the temperatures of which can be independently controlled. The method of division depends on the positions of the first heating module 200 and the second heating module 300 within them, and is not limited in this embodiment. Figure 2This paper illustrates one possible method for dividing the heating zone when applied to an electric blanket, where the two zones are defined as a first heating zone and a second heating zone, respectively. In terms of circuit structure, both the first heating module 200 and the second heating module 300 are connected to the MCU control module 100. The MCU control module 100 can adjust the heating temperature of the first heating module 200 and the second heating module 300 by adjusting the duty cycle of the PWM signal.

[0023] The first heating module 200 controls its heating temperature through its internal first output control unit 210, defining the heating temperature of the first heating module 200 as the first heating temperature; the second heating module 300 controls its heating temperature through its internal second output control unit 310, defining the heating temperature of the second heating module 300 as the second heating temperature; it can be understood that the first heating temperature and the second heating temperature can be different. Both the first output control unit 210 and the second output control unit 310 are equipped with devices such as MOSFETs or relays to achieve control of heating power.

[0024] In addition, although Figure 1 As not limited by the above description, the low-pressure temperature control device in this embodiment is powered by a 220V AC power supply, and after being converted by an adapter, it powers the MCU control module 100 and other modules. Finally, it stably outputs an output voltage of no more than 36V at the first output control unit 210 and the second output control unit 310, ensuring heating under low-pressure conditions and thus reducing the risk of electric shock.

[0025] This embodiment designs a low-voltage temperature control device, including an MCU control module 100, a first heating module 200, and a second heating module 300. The MCU control module 100 is connected to and controls both the first heating module 200 and the second heating module 300. The first heating module 200 includes a first output control unit 210, and the second heating module 300 includes a second output control unit 310. Compared with traditional direct control via 220V voltage, control via the first output control unit 210 and the second output control unit 310 provides a certain degree of isolation, enabling output under low-voltage conditions and reducing the risk of electric shock for users.

[0026] On the other hand, the first heating module 200 and the second heating module 300 are respectively located in different areas, which can heat different areas at different temperatures, allowing users to flexibly choose heating solutions and improve the user experience of heating.

[0027] In some embodiments, the first heating module 200 further includes a first current detection unit 220, and the second heating module 300 further includes a second current detection unit 320; The first current detection unit 220 is used to detect the first operating current of the first heating module 200, and is configured to feed back an abnormal signal to the MCU control module 100 when an abnormality is detected in the first operating current. The second current detection unit 320 is used to detect the second operating current of the second heating module 300, and is configured to feed back an abnormal signal to the MCU control module 100 when an abnormality is detected in the second operating current.

[0028] To further enhance safety, a first current detection unit 220 is provided in the first heating module 200, and a second current detection unit 320 is provided in the second heating module 300. During heating, the first current detection unit 220 detects the operating current of the first heating module 200, defining it as the first operating current; the second current detection unit 320 detects the operating current of the second heating module 300, defining it as the second operating current. When abnormal problems such as overcurrent, short circuit, or open circuit occur in the circuit, they will be directly reflected in the first operating current and / or the second operating current. Thus, the first current detection unit 220 and the second current detection unit 320 can detect current abnormalities in a timely manner, thereby feeding back an abnormal signal to the MCU control module 100 when an abnormal problem occurs. The MCU control module 100 then performs emergency actions such as shutting down the device, improving safety during use.

[0029] In some embodiments, the first heating module 200 further includes a first temperature detection unit 230, and the second heating module 300 further includes a second temperature detection unit 330; The first temperature detection unit 230 is used to detect the first heating temperature of the first heating module 200 and is configured to send the first heating temperature to the MCU control module 100 so that the MCU control module 100 controls the first output control unit 210 according to the first heating temperature. The second temperature detection unit 330 is used to detect the second heating temperature of the second heating module 300 and is configured to send the second heating temperature to the MCU control module 100 so that the MCU control module 100 controls the second output control unit 310 according to the second heating temperature.

[0030] To further enhance the user experience, a first temperature detection unit 230 is provided in the first heating module 200, and a second temperature detection unit 330 is provided in the second heating module 300. During the heating process, the first temperature detection unit 230 can detect the first heating temperature of the first heating module 200, i.e., the first heating temperature under the control of the first output control unit 210; the second temperature detection unit 330 can detect the second heating temperature of the second heating module 300, i.e., the second heating temperature under the control of the second output control unit 310. The first and second heating temperatures are fed back to the MCU control module 100, enabling the MCU control module 100 to determine whether to continue heating, temporarily suspend heating to lower the temperature, or maintain the current temperature, thereby achieving temperature regulation and improving the heating user experience of the product.

[0031] In some embodiments, the device further includes a touch input module 400, which is connected to the MCU control module 100. The touch input module 400 is used to receive external touch input operations and send the corresponding generated touch sensing signals to the MCU control module 100.

[0032] Optionally, the device may also include a touch input module 400, which includes at least a touch panel and corresponding capacitive sensing devices. The touch panel can be equipped with multiple touch buttons according to different control functions of the product, such as turning on / off, increasing / decreasing temperature, etc. When different touch buttons are triggered by touch input operations such as clicking or swiping, different touch sensing signals will be generated. Based on this, the MCU control module 100 can receive and analyze the touch sensing signals to determine the function triggered by the user control, and then execute the corresponding operation to realize touch control and improve the convenience of product control.

[0033] In some embodiments, the device further includes a setting storage module 500 for storing a preset heating temperature. The MCU control module 100 is configured to adjust a first heating temperature and / or a second heating temperature based on the preset heating temperature. The preset heating temperature is set by an external operation input.

[0034] Optionally, the device may also include a setting storage module 500, which functions as a cache module storing the user-set heating temperature. When the product leaves the factory, the device heats according to the default factory-set heating temperature. Users can adjust the heating temperature (including a first heating temperature and a second heating temperature) according to their needs. The set heating temperature is stored in the setting storage module 500 as a preset heating temperature. Unlike existing technologies that may only allow setting the heating temperature to a fixed level, the device provided in this embodiment allows for flexible temperature adjustment. Furthermore, during subsequent use, the preset heating temperature can be read from the setting storage module 500, and the MCU control module 100 uses this preset heating temperature as a standard to regulate the first and / or second heating temperatures. This allows the product to automatically adjust to the user's preferred heating temperature after startup, improving the user experience.

[0035] In some embodiments, the device further includes an LCD display module 600, which is connected to the MCU control module 100 and is used to display a first heating temperature and a second heating temperature.

[0036] Optionally, the device may also include an LCD display module 600. Unlike digital tube displays, LCD technology provides colorful and more diverse display content. For example, by connecting to the MCU control module 100, it can acquire the first and second heating temperatures and display them on the LCD display module 600, thus visually indicating the current heating temperature to the user. Furthermore, the LCD display module 600 can also be used to display warning messages when abnormal problems such as current or temperature anomalies occur, reminding users to pay attention to product safety.

[0037] In some embodiments, the device further includes an Internet of Things (IoT) module 700, which is connected to the MCU control module 100 and is used to support communication between the MCU control module 100 and an external terminal.

[0038] Furthermore, in order to integrate the device with smart home technology, an Internet of Things (IoT) module 700 can also be installed in the device. This IoT module 700 is also connected to the MCU control module 100, enabling the MCU control module 100 to communicate with external terminals, such as the user's mobile terminal or other smart home products. This allows users to remotely control the device through an application on their mobile terminal, thereby improving the smart user experience of the product.

[0039] In some embodiments, the device further includes a remote controller 900, which is used to receive external operation commands, convert the operation commands into corresponding control signals, and wirelessly transmit the control signals to the MCU control module 100. The remote controller 900 is configured to transmit control signals based on the 433MHz frequency band.

[0040] The remote controller 900 is a physically independent module. It communicates wirelessly with the MCU control module 100 by transmitting radio frequency signals in the 433MHz band. Signals sent from the remote controller 900 to the MCU control module 100 are defined as control signals. Furthermore, the remote controller 900 has control buttons on its panel, which can be mechanical or touch-sensitive. When a user triggers a control button, the remote controller 900 determines the operation command based on its circuit configuration and then sends out the corresponding control signal.

[0041] By setting the remote control 900, the device can be remotely controlled.

[0042] In some embodiments, the device further includes a communication module 800, which is connected to the MCU control module 100 and is used to support wireless communication between the MCU control module 100 and the remote controller 900.

[0043] On the other hand, in addition to the IoT module 700 used to support smart home technology, the device can also be equipped with a communication module 800. Unlike the IoT module 700, the communication module 800 and the IoT module 700 are used to implement different communication methods. The communication module 800 is dedicated to supporting communication with devices such as the remote control 900, expanding the wireless communication methods that the device can support and improving the ease of use.
