[0001] This utility model relates to the field of bedding, specifically to a power supply circuit for a heating device that supports portable power supply and a mattress. Background Technology

[0002] Sleep quality is directly related to health, and there are many reasons for poor sleep quality. Studies have shown that ambient temperature has a significant impact on sleep quality, especially in cold winters when people often use various methods to ward off the cold and improve sleep quality. Currently, the most common heating methods include air conditioning, underfloor heating, electric blankets, and electric mattresses. Among these, electric mattresses have gained popularity due to their low power consumption, integrated design, and ease of use.

[0003] Electric mattresses are primarily used during sleep to raise the surface temperature of the mattress for warmth. They can also be used to dehumidify the mattress. Additionally, for people with rheumatism or lumbar spine problems, they can accelerate blood circulation and help alleviate these conditions. The heating effect provides a more comfortable and natural feeling. This is especially important for people who work or live outdoors, where the damp and cold environment necessitates heating to improve sleep quality and effectively remove moisture. However, due to the diverse types of power sources available outdoors, including external AC power, power banks, and generators, existing mattress heating components cannot differentiate between these types of power sources. This limits the types of power that can be used and can lead to heating device malfunctions, power overload, or excessive power consumption due to using incompatible power sources, posing safety hazards and affecting the user experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a power supply circuit and mattress for a heating device that supports portable power supply. The circuit detects the power supply voltage through a voltage detection unit and adjusts the voltage parameters of the power supply through a transformer unit. This allows the circuit board to adjust the power supply and deliver electrical energy to the heating unit in accordance with its operating requirements. This ensures the normal operation of the heating unit and also protects the heating unit, power supply, and circuit board, ensuring safety and improving the user experience.

[0005] This invention is achieved through the following method: a power supply circuit for a heating device supporting portable power supply, comprising a circuit board. The circuit board has voltage detection pins, a transformer pin group, and an output pin group. A voltage detection unit is connected to the voltage detection pins, a transformer unit is connected to the transformer pin group, and a heating unit is connected to the output pin group. The power supply unit supplies power to the voltage detection unit and the transformer unit respectively. The voltage detection unit detects the power supply voltage, and the transformer unit adjusts the power supply to a preset voltage and supplies it to the heating unit through the output pin group. By setting the voltage detection unit and the transformer unit on the circuit board, the power supply voltage is detected by the voltage detection unit, and the voltage parameters of the power supply are adjusted by the transformer unit. This allows the circuit board to adjust the power supply and supply electrical energy to the heating unit that meets its operating requirements, ensuring the normal operation of the heating unit and protecting the heating unit, power supply, and circuit board, ensuring safety and improving the user experience. The voltage detection unit is connected to the circuit board through the voltage detection pins, the transformer unit is connected to the circuit board through the transformer pin group, and the heating unit is connected to the circuit board through the output pin group, ensuring smooth transmission of power, data, and signals.

[0006] Preferably, the voltage detection unit includes a comparator. The comparator compares the voltage of the power supply unit and transmits the result to the circuit board via a voltage detection pin. The comparator compares two values ​​and determines their relationship. In use, the comparator compares the power supply voltage parameter with a preset threshold voltage parameter. The threshold voltage parameter matches the voltage required for the heating unit to operate, providing a reference for the transformer unit's operation and ensuring that the power supply voltage, after adjustment by the transformer unit, meets the operating requirements of the heating unit. The voltage detection pin connects the voltage detection unit and the circuit board, ensuring that the detection signal can be effectively received by the circuit board.

[0007] Preferably, the transformer pin assembly includes a boost pin and a buck pin, and the transformer unit includes a boost section connected between the boost pin and the power supply unit, and a buck section connected between the power supply unit and the buck pin. The boost pin and the buck pin are independently switched on and off under the drive of the circuit board. The boost pin is used to connect the circuit board and the boost section. The boost section receives electrical energy from the power supply unit and transmits it to the circuit board through the boost pin after a boost operation. The buck pin is used to connect the circuit board and the buck section. The buck section receives electrical energy from the power supply unit and transmits it to the circuit board through the buck pin after a buck operation. The voltage of the power supply from the power supply unit is regulated by the boost section or the buck section, so that the circuit board obtains electrical energy that meets the operating requirements of the heating unit.

[0008] Preferably, the circuit board is provided with low-voltage pins, to which a backup battery unit is connected. The power supply unit is connected to the backup battery unit via a low-voltage converter, allowing the circuit board to obtain the power required for operation through the low-voltage pins. The backup battery unit is connected to the circuit board via the low-voltage pins and also to the power supply unit via the low-voltage converter. The low-voltage converter steps down the power from the power supply unit to form low-voltage energy stored in the backup battery unit. The backup battery unit uses this low-voltage energy to stably power the circuit board, ensuring its long-term stable operation. Especially in the event of a power supply unit failure or power shortage, the energy stored in the backup battery unit can still power the circuit board, ensuring that the circuit board can cope with sudden situations where the power supply unit cannot provide power and can perform operations such as parameter reset and heating unit shutdown.

[0009] Preferably, the circuit board is provided with a communication pin group, which is connected to the communication unit, and the backup battery unit provides the power required for the operation of the communication unit. The communication pin group is connected to the communication unit, which is used to realize signal transmission.

[0010] Preferably, there are at least two heating units, each independently configured. The output pin group includes output pins corresponding to each heating unit, allowing each heating unit to be started, stopped, and switched independently. Each heating unit is connected to the transformer unit and receives the power required for operation. Having multiple output pins facilitates the connection of multiple heating units, enabling independent control of each unit and allowing users to adjust the number of heating units activated and their operating power as needed.

[0011] Preferably, the circuit board is provided with current detection pins, to which current detection units are connected. The current detection units are connected to each heating unit via detection ports to collect and monitor the current within each heating unit. The current detection units are connected to the circuit board via current detection pins and also to each heating unit via wires. The current detection units detect the current flowing through each heating unit and transmit the data to the circuit board, providing feedback on whether the number of operating heating units matches the preset number, thereby ensuring that the heating units operate according to the preset requirements.

[0012] Preferably, the circuit board is provided with temperature detection pins, and a temperature detection unit is connected to the temperature detection pins. The detection part of the temperature detection unit is located at the corresponding heating unit. The temperature detection unit is connected to the circuit board through the temperature detection pins. The temperature detection unit detects the temperature of the corresponding heating unit and transmits a temperature signal to the circuit board to ensure that the temperature of the heating unit reaches the preset requirements and to prevent the heating unit from posing a safety hazard due to excessive temperature.

[0013] Preferably, the power supply unit is a portable power source or a regular power source. By increasing the range of usable power sources, it is easier for users to provide power to the heating unit, thereby effectively improving ease of use.

[0014] A mattress includes a support layer and a heating layer with a control component. The heating layer covers the support layer and has a plurality of heating units. The control component includes a power supply circuit, which controls the start and stop operation of each heating unit. The support layer supports the user, and the heating layer, placed on top of the support layer, facilitates the upward transfer of heat generated by the heating layer to the user, effectively improving the heating effect. The control component includes a power supply circuit for receiving power and controlling the operation of the heating units, allowing for convenient user operation and enhancing the user experience.

[0020] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1:

[0022] This embodiment provides a power supply circuit for a heating device that supports portable power supply.

[0023] As shown in Figure 1, the power supply circuit includes a circuit board 1. The circuit board 1 has a voltage detection pin 2, a transformer pin group, and an output pin group. A voltage detection unit 3 is connected to the voltage detection pin 2, a transformer unit 6 is connected to the transformer pin group, and a heating unit 15 is connected to the output pin group. The power supply unit 11 supplies power to the voltage detection unit 3 and the transformer unit 6 respectively. The voltage detection unit 3 detects the power supply voltage, and the transformer unit 6 adjusts the power supply to a preset voltage and supplies it to the heating unit 15 through the output pin group. By setting the voltage detection unit 3 and the transformer unit 6 on the circuit board 1, the circuit board 1 can adjust the power supply and supply the heating unit 15 with electrical energy that meets its operating requirements. This ensures the normal operation of the heating unit 15, protects the heating unit 15, the power supply, and the circuit board 1, ensures safety, and improves the user experience.

[0024] In this embodiment, the circuit board 1 is configured with various pins to effectively connect with different functional units, enabling reliable transmission of power, signals, and data. These pins include voltage detection pin 2 connecting the voltage detection unit 3 and the circuit board 1, transformer pin group connecting the transformer unit 6 and the circuit board 1, output pin group connecting the heating unit 15 and the circuit board 1, low-voltage pin 9 connecting the backup battery unit 10 and the circuit board 1, communication pin group 13 connecting the communication unit 14 and the circuit board 1, current detection pin 17 connecting the current detection unit 18 and the circuit board 1, and circuit detection pin connecting the temperature detection unit 20 and the circuit board 1. The corresponding functional units are soldered to the corresponding pins for conductivity, which not only serves to fix and position the circuit board 1 and each functional unit, but also ensures that each pin can be correctly connected, preventing short circuits, overloads, and other faults between the functional units and the circuit board 1 due to incorrect connections, thus ensuring the safety of the power supply circuit.

[0025] In this embodiment, the voltage detection unit 3 is equipped with a comparator (as shown in Figure 2). The comparator compares the voltage of the power supply unit 11 and transmits the data to the circuit board 1 through the voltage detection pin 2. The comparator can compare two data points and provide a comparison result. The voltage detection unit 3 is connected to the power supply unit 11 and compares the voltage of the power supply provided by the power supply unit 11 with a preset threshold voltage parameter to determine whether the voltage of the power supply in the power supply unit 11 is high or low. Then, it controls the transformer unit 6 to perform a transformer operation on the power supply from the power supply unit 11 and finally obtains the power supply that meets the operating requirements of the heating unit 15.

[0026] In this embodiment, the power supply unit 11 is either a portable power source or a standard power source. By adapting to different types of power sources, the power supply requirements of the heating device are reduced, allowing the heating device to use various power sources. Since portable power sources and standard power sources have different voltages, it is necessary to identify the power source type and perform corresponding voltage conversion operations during use to convert the power supply voltage to a value suitable for the operation of the heating unit 15, ensuring the safe operation of the heating unit 15.

[0027] In this embodiment, the transformer pin group includes a boost pin 4 and a buck pin 5, and the transformer unit 6 includes a boost section 7 connected between the boost pin 4 and the power supply unit 11 and a buck section 8 connected between the power supply unit 11 and the buck pin 5. The boost pin 4 and the buck pin 5 are independently switched on and off under the drive of the circuit board 1. In a preferred embodiment, the operating voltage of the heating unit 15 is set to the threshold voltage parameter, thereby facilitating the transformer unit 6 to transform the power supply from the power supply unit 11. Specifically, when the power supply voltage in the power supply unit 11 is greater than the threshold voltage parameter, the transformer unit 6 performs a step-down operation on the power supply from the power supply unit 11 through the step-down section 8. When the power supply voltage in the power supply unit 11 is less than the threshold voltage parameter, the transformer unit 6 performs a step-up operation on the power supply from the power supply unit 11 through the step-up section 7. When the power supply voltage in the power supply unit 11 is equal to or close to the threshold voltage parameter, the transformer unit 6 does not perform a transformation operation on the power supply from the power supply unit 11. In this way, it is ensured that the heating unit 15 can operate under a suitable voltage, thus protecting the power supply unit 11, the circuit board 1, and the heating unit 15.

[0028] In this embodiment, the circuit board 1 is provided with a low-voltage pin 9, which is connected to a backup battery unit 10. The power supply unit 11 is connected to the backup battery unit 10 through a low-voltage transformer unit 12, so that the circuit board 1 can obtain the power required for operation through the low-voltage pin 9. The low-voltage transformer unit 12 performs a voltage reduction operation on the power supply in the power supply unit 11 and provides stored electrical energy to the backup battery unit 10. The electrical energy stored in the backup battery unit 10 is used to power the circuit board 1 for normal operation, ensuring that the circuit board 1 can still operate when the power supply fails, thereby ensuring the safety of the circuit board 1 and facilitating subsequent normal use.

[0029] In this embodiment, the circuit board 1 is provided with a communication pin group 13, which is connected to the communication unit 14. The backup battery unit 10 provides the power required for the operation of the communication unit 14. The communication unit 14 is used for human-computer interaction and data transmission with wireless devices. It ensures that the operation of the circuit board 1 is controlled by the user through human-computer interaction, and realizes data sharing through data transmission with wireless devices, thereby providing a basis for operational decisions.

[0030] In this embodiment, there are at least two heating units 15, which are independently configured. The output pin group includes output pins 16 that correspond one-to-one with each heating unit 15, so that each heating unit 15 can be started, stopped, and switched independently. The heating unit 15 is connected to the transformer unit 6 and obtains the power required for operation. Preferably, there are eight heating units 15, which are distributed to form multiple heating zones, allowing for independent operation and heating for different body parts of the user, effectively improving the user experience.

[0031] In this embodiment, the circuit board 1 is provided with a current detection pin 17, and a current detection unit 18 is connected to the current detection pin 17. The current detection unit 18 is connected to each heating unit 15 through a detection port to collect and detect the current in each heating unit 15. The current detection unit 18 is connected in series with each heating unit 15 through a wire, so that the current generated by each heating unit 15 during operation will pass through the current detection unit 18. By detecting the current flow rate, the number of operating heating units 15 is detected, which is then used to evaluate whether each heating unit 15 is effectively controlled.

[0032] In this embodiment, the circuit board 1 is provided with a temperature detection pin 19, and a temperature detection unit 20 is connected to the temperature detection pin 19. The detection part of the temperature detection unit 20 is located at the corresponding heating unit 15. The temperature detection unit 20 is used to detect the temperature of the heating unit 15, and then evaluate the operating effect of the corresponding heating unit 15. This ensures that the heating unit 15 can reach the preset temperature requirement through continuous operation, and also cuts off the power after the heating unit 15 reaches the preset temperature, ensuring that the heating unit 15 will not overheat due to continuous operation, thus ensuring safe use.

[0033] Example 2:

[0034] Compared to Embodiment 1, this embodiment provides a mattress.

[0035] As shown in Figure 3, a mattress includes a support layer 22 and a heating layer 23 with a control component 21. The heating layer 23 covers the support layer 22 and has several heating units 15. The control component 21 contains a power supply circuit, which controls the start and stop of each heating unit 15. The power supply circuit in the control component 21 receives external power and, after transformation, supplies it to each heating unit 15, ensuring that each heating unit 15 can start and stop independently, providing warmth to the user and improving comfort.

[0036] In this embodiment, the control component 21 is placed outside the heating layer 23, which will not cause any foreign body sensation to the user lying down, and will also make it convenient for the user to operate and independently control the heating unit 15.

[0037] In this embodiment, the heating layer 23 is laid on top of the support layer 22, which provides effective support for the user. The support layer 22 can be an airbag, spring pad, or sponge pad, etc., and all of these should be considered as specific implementations of this embodiment.

[0038] In this embodiment, the heating layer 23 provides the user with the heat needed for warmth. The heating layer 23 and the support...

[0039] Layer 22 is set up independently, so that heating layer 23 can be transported and used independently after disassembly.

[0040] The specific structure and function of the power supply circuit described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
