[0024] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0025] like Figure 1-7 As shown, this embodiment of a radio signal transmission type cotton candy machine furnace head includes a furnace body 10, a furnace top 11, a heating cavity disposed on the furnace top 11, a heating wire 12 disposed in the heating cavity, and a first power supply module for supplying power to the heating wire 12; it also includes a temperature acquisition module 2, a temperature control module 3, and a second power supply module for supplying power to the temperature acquisition module 2; the temperature acquisition module 2 includes a temperature sensor 21, a thermocouple digital converter, a first main controller 22, and a transmitting antenna unit; the temperature sensor 21 is installed in the heating cavity and is used to detect the temperature in the heating cavity; the temperature sensor 21 is electrically connected to the first main controller 22 through the thermocouple digital converter; the transmitting antenna unit is electrically connected to the first main controller 22; the temperature control module 3 includes a second main controller 31 and a receiving antenna unit; the receiving antenna unit is used to receive data from the transmitting antenna unit; the second main controller 31 is electrically connected to the first power supply module and is used to control the output power of the first power supply module.

[0026] After the second power supply module provides positive DC power to the temperature acquisition module 2, the temperature sensor 21 collects the temperature inside the heating cavity. The weak signal collected is amplified by a thermocouple-to-digital converter. Finally, the amplified signal is converted into precise temperature data by the first main controller 22. The transmitting antenna unit modulates the temperature data and transmits it wirelessly via electromagnetic waves (usually using a 2.4GHz signal). This signal is received by the antenna in the receiving antenna unit of the temperature control module 3. The transceiver chip in the receiving antenna unit demodulates the signal, restores the temperature data, and then the MAX485 transceiver chip sends the data to the second main controller 31 (PLC), ultimately achieving long-distance wireless data transmission and reception. The above setup enables precise temperature control during the heating process and also achieves efficient data transmission and processing through radio signal transmission, improving reliability and flexibility. This ensures that the cotton candy machine operates within the optimal temperature range.

[0027] like Figure 1-7 As shown in this embodiment, a radio signal transmission type cotton candy machine burner head, the second power supply module includes a transmitting coil 4, a wireless transmitting circuit, a receiving coil 5, and a wireless receiving circuit; the wireless transmitting circuit is used to drive the transmitting coil 4 to power the receiving coil 5; the wireless receiving circuit is used to convert the induced voltage from the receiving coil 5 into a DC voltage and power the temperature acquisition module 2.

[0028] Specifically, the first interface 6 provides operating voltage to the charging transmitter chip U1. The charging transmitter chip U1 converts the input DC power into alternating current. When the alternating current passes through the transmitting coil 4, it generates an alternating magnetic field around the transmitting coil 4. At this time, the receiving coil 5 is in the alternating magnetic field generated at the transmitting end. According to Faraday's law of electromagnetic induction, an induced electromotive force, i.e., an induced voltage, is generated in the receiving coil 5. The induced voltage is AC power, which needs to be rectified and filtered by a rectifier and filter circuit composed of diode D1, capacitor C10, and capacitor C11 to convert it into smooth DC power, providing a stable power supply to the load (temperature acquisition module 2) to achieve the power supply purpose.

[0029] like Figure 1As shown in this embodiment, a wireless signal transmission type cotton candy machine burner head includes a wireless transmission circuit comprising a rechargeable transmitter chip U1 and a first interface 6 for supplying power to the rechargeable transmitter chip U1; the positive terminal of the first interface 6 is electrically connected to the first pin of the rechargeable transmitter chip U1; the negative terminal of the first interface 6 is grounded; the ground terminal of the rechargeable transmitter chip U1 is grounded; one end of the transmitting coil 4 is electrically connected to the positive terminal of the first interface 6; the other end of the transmitting coil 4 is electrically connected to the third pin of the rechargeable transmitter chip U1; a capacitor C2 is connected in parallel across the two ends of the transmitting coil 4; the first pin of the rechargeable transmitter chip U1 is also grounded through a capacitor C1; the positive terminal of the first interface 6 is electrically connected to the eighth pin of the rechargeable transmitter chip U1 through a resistor R3; a resistor R1 is electrically connected between the eighth and seventh pins of the rechargeable transmitter chip U1; the positive terminal of the first interface 6 is also electrically connected to the sixth pin of the rechargeable transmitter chip U1 through a resistor R4.

[0030] Among them, the first pin of the charging transmitter chip U1 is VDD, the third pin is the power output terminal, the fourth pin is the ground terminal, the sixth pin is the function adjustment terminal, the seventh pin is the voltage detection terminal, and the eighth pin is the detection terminal; the first interface 6 introduces a 5-12V bias voltage from the outside to enable the charging transmitter chip U1 to work normally, and the resistors R1 and R3 are the start-up resistors.

[0031] like Figure 2 As shown in this embodiment, a wireless signal transmission type cotton candy machine burner head includes a wireless receiving circuit comprising a charging receiving chip U2 and a second interface 7 connected to the temperature acquisition module 2. The second interface 7 is used to power the temperature acquisition module 2. One end of the receiving coil 5 is electrically connected to the second pin of the charging receiving chip U2 through a diode D1. The other end of the receiving coil 5 is grounded. A capacitor C10 is connected in parallel across the two ends of the receiving coil 5. The second pin of the charging receiving chip U2 is also electrically connected to the seventh pin of the charging receiving chip U2 through a resistor R78. The third pin of the charging receiving chip U2 is electrically connected to the positive terminal of the second interface 7 through an inductor L5. The third pin of the charging receiving chip U2 is also grounded through a reverse-mounted diode D2. The positive terminal of the second interface 7 is also grounded through a capacitor C12. The positive terminal of the second interface 7 is connected to ground in sequence through resistors R79 and R80. The fifth pin of the charging receiving chip U2 is electrically connected between resistors R79 and R80.

[0032] In this circuit, pin 1 of the charging receiver chip U2 is the output voltage adjustment sampling terminal, pin 3 is the ground pin, pin 4 is the voltage regulated output terminal, pin 5 is the voltage input pin, and pin 7 is the enable pin. A rectifier and filter circuit is formed by diode D1, capacitor C10, and capacitor C11. Furthermore, to address the issue of significant energy loss in the transmitting coil 4, resonance is introduced in the peripheral circuits of both the charging transmitter chip U1 and the charging receiver chip U2, utilizing the complementary characteristics of inductors and capacitors. This ensures that both the transmitter and receiver operate at the same resonant frequency, greatly improving energy transfer efficiency.

[0033] like Figure 1 As shown in this embodiment, the charging transmitter chip U1 is model XKT-510, which is a radio signal transmission type cotton candy machine burner head.

[0034] like Figure 2 As shown in this embodiment, the charging receiver chip U2 is model T3168, which is a radio signal transmission type cotton candy machine burner.

[0035] like Figure 3 As shown in this embodiment, a radio signal transmission type cotton candy machine burner head, wherein the temperature sensor 21 adopts a K-type thermocouple; the thermocouple digital converter is model MAX31885.

[0036] A type K thermocouple is based on the Seebeck effect to collect thermal signals. It consists of two different metals forming a closed circuit. When the two junctions are at different temperatures, a thermoelectric potential, i.e., a voltage, is generated in the circuit that is proportional to the temperature difference.

[0037] The MAX31885 is a thermocouple-to-digital converter that automatically compensates for the thermoelectric potential generated by a K-type thermocouple based on the measured cold junction temperature. This ensures the accuracy of the measurement results regardless of changes in ambient temperature. Furthermore, since the thermoelectric potential signal output by a K-type thermocouple is very weak, the MAX31885 internally amplifies this weak signal for subsequent processing.

[0038] like Figure 5-7 As shown in this embodiment, a radio signal transmission type cotton candy machine burner head further includes a rotating shaft 13, a transmission component 14, and a motor 15; the motor 15 is connected to the furnace body 10 through a mounting plate 16; the transmission component 14 is mounted on the mounting plate 16; the output end of the motor 15 causes the rotating shaft 13 to rotate through the transmission component 14; the furnace top 11 is mounted on the top of the rotating shaft 13.

[0039] During operation, the furnace body 10 remains stationary. The motor 15 drives the rotating shaft 13 to rotate via the transmission component 14 (which may be a belt), thereby causing the furnace top 11 at the top of the rotating shaft 13 to rotate within the furnace body 10. Simultaneously, the first power supply module drives the heating wire 12 to operate, causing the temperature inside the heating chamber to rise. The above configuration makes the overall layout of the cotton candy machine compact.

[0040] like Figure 5-7 As shown in this embodiment, a radio signal transmission type cotton candy machine burner head further includes a fixed plate 17, a first coil slot for accommodating the transmitting coil 4, and a second coil slot for accommodating the receiving coil 5; the first coil slot and the second coil slot are both arranged around the rotating shaft 13; the wireless receiving circuit is mounted on the fixed plate 17; the fixed plate 17 and the second coil slot are both fixedly connected to the rotating shaft 13; the transmitting coil 4 is connected to the mounting plate 16 through a fixed base 18; the wireless transmitting circuit is mounted on the fixed base 18.

[0041] Specifically, during operation, the rotating shaft 13 drives the wireless receiving circuit on the fixed plate 17 to rotate simultaneously, while the wireless transmitting circuit is mounted on the mounting plate 16 via the fixed base 18. This configuration not only enables the rotation of the furnace top 11 via the motor 15 and transmission components 14, but also provides stable wireless power supply via the transmitting coil 4 and receiving coil 5 arranged around the rotating shaft 13. While maintaining a compact structure, it ensures efficient wireless power supply even during complex mechanical movements.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
