[0027] In some embodiments, this application provides a wireless thermometer for brewing, comprising: a wireless thermometer body 10, a battery assembly 20, and a wireless charging assembly 30. The wireless thermometer body 10 is used to acquire the temperature of the koji material, and the battery assembly 20 is electrically connected to the wireless thermometer body 10. The wireless charging assembly 30 is disposed on and electrically connected to the battery assembly 20. The wireless charging assembly 30 includes a receiving coil 32 and a charging module 33 electrically connected to the receiving coil 32. The receiving coil 32 receives and couples the magnetic energy of the transmitting coil into an AC signal to the charging module 33. The charging module 33 converts the AC signal into DC power and charges the battery assembly 20.

[0028] The aforementioned wireless thermometer for brewing incorporates a wireless charging component 30 on the battery assembly 20. A receiving coil 32 receives the magnetic energy from the transmitting coil and couples it to the charging module 33. The charging module 33 then converts the AC signal into DC power and supplies it to the battery assembly 20 for charging. This eliminates the need for a charging cable, making the wireless thermometer more flexible and convenient to use, reducing operational complexity and safety hazards. Furthermore, the wireless charging component 30 enables wireless charging of the thermometer body 10, preventing damage to the charging interface caused by frequent plugging and unplugging, thus improving the durability and reliability of the wireless thermometer.

[0029] It should be noted that during the charging process, the transmitting coil generates magnetic field energy after being energized; the receiving coil 32 receives the magnetic field energy and couples it into an AC signal. After receiving the AC signal, the charging module 33 converts it into DC power and delivers it to the battery assembly 20 to achieve wireless charging.

[0030] The transmitting coil generates magnetic field energy when energized. When the receiving coil 32 is near or placed on the transmitting coil, it receives the magnetic field energy and couples it into an AC signal. The charging module 33 converts the AC signal into DC power to charge the battery assembly 20.

[0031] Battery assembly 20 refers to a device with energy storage and charging functions, which may be, but is not limited to, lithium battery 21, sodium battery 21, etc. When monitoring temperature, battery assembly 20 can power the wireless thermometer body 10. When the battery assembly 20 is low on power, the wireless thermometer can be automatically or manually placed above the transmitting coil for wireless charging. The wireless thermometer body 10 can sense and acquire the temperature of the material in a non-contact manner, which may be, but is not limited to, thermocouple sensing, infrared sensing, etc.

[0032] In some specific examples, the wireless thermometer body 10 includes a sensor and a temperature measuring rod, with the sensor located inside the temperature measuring rod.

[0033] Furthermore, in this embodiment, the wireless charging component 30 is fixed to the battery component 20, facilitating a high degree of integration between the wireless charging component 30 and the wireless thermometer body 10. This high integration not only reduces the overall size but also improves the reliability and durability of the device. In addition, this design makes it easier for users to carry and use, enhancing the user experience.

[0034] Furthermore, the charging module 33 includes an energy conversion board 331, a power supply board 332, and a main control board 334 connected in sequence. The energy conversion board 331 is electrically connected to the receiving coil 32, and the main control board 334 is electrically connected to the battery assembly 20. Therefore, when the receiving coil 32 transmits an AC signal to the energy conversion board 331, the energy conversion board 331 converts the AC signal into DC power, which can then be transmitted to the battery assembly 20 via the power supply board 332 and the main control board 334.

[0035] It should be noted that, in some embodiments, the energy conversion board 331 may include rectification, filtering, voltage regulation, voltage stabilization circuits, echo circuits, power control circuits, protection circuits, and indicator light circuits, which are used to convert the coupled AC signal into 5V DC power and transmit it to the power supply board 332. The energy conversion board 331 may support the WPC2.0 (Wireless Power Consortium 2.0) wireless charging protocol and support 5V, 9V, and 12V transmission signals.

[0036] Meanwhile, the power supply board 332 may include a charging management circuit, a boost circuit, and a buck circuit, etc., for charging management of the lithium battery 21, generating various power signals of 5V, 3.3V, and 2.5V for use by the main control board 334. In charging management, a built-in management circuit can be incorporated to monitor the charging status in real time, including key parameters such as charging current, voltage, and battery 21 temperature, ensuring the safety and stability of the charging process. Furthermore, this management circuit can automatically adjust the charging power according to the battery 21's status, extending the battery 21's lifespan.

[0037] The main control board 334 may include a battery 21 power acquisition circuit, a multi-channel temperature acquisition circuit, a wireless communication circuit, a USB (Universal Serial Bus) interface circuit, a main control MCU (Microcontroller Unit) circuit, a button circuit, an indicator light circuit, a watchdog circuit, etc. It should be noted that the energy conversion board 331, the power supply board 332, and the main control board 334 can all be existing components, and their connection circuits can be directly referenced from existing literature or products.

[0038] In addition, the circuit structure introduced in this application, such as the energy conversion board 331, the power supply board 332, and the main control board 334, facilitates the rapid conversion of the existing wired charging method of wireless thermometers to wireless charging method, thereby improving the efficiency of equipment modification.

[0039] In some embodiments, the main control board 334 includes a first board portion 33a and a second board portion 33b, which are arranged perpendicularly. The first board portion 33a is electrically connected to the power board 332, and the second board portion 33b is electrically connected to the battery assembly 20. It can be seen that designing the main control board 334 as two parts, with these two parts distributed perpendicularly to each other, not only enables effective control of wireless charging but also reduces the space occupied by the main control board 334, facilitating a reduction in the overall size of the wireless thermometer.

[0040] It should be noted that the main control board 334 can be a circuit board. During assembly, the main control board 334 can be divided into two parts: a first board portion 33a and a second board portion 33b, which are perpendicularly distributed and form a T-shape. In some specific examples, the surface of the first board portion 33a is parallel to the axis of the battery assembly 20, and the surface of the second board portion 33b is perpendicular to the axis of the battery assembly 20.

[0041] In addition, the near-T-shaped structure makes it more symmetrical on the left and right, and the center of gravity is more central and closer to the surface of the object being tested, so that the object being tested will not be damaged by tilting due to an unstable center of gravity or a high center of gravity.

[0042] In some embodiments, the charging module 33 further includes an adapter port 333, which is located between the energy conversion board 331 and the power board 332, and is electrically connected to both the energy conversion board 331 and the power board 332. It is understood that the energy conversion board 331 and the power board 332 are connected via the adapter port 333, thereby facilitating the connection between the energy conversion board 331 and the power board 332 and improving assembly efficiency.

[0043] It should be noted that the 333 adapter port can have various structures, such as, but not limited to, a Type-C interface or a USB interface.

[0044] In some embodiments, the wireless charging component 30 is disposed at one end of the battery component 20 along its own axis, and the receiving coil 32 is located on the side of the charging module 33 facing away from the battery component 20. It is understood that the receiving coil 32 being positioned away from the battery component 20 reduces electrical interference between the receiving coil 32 and the battery component 20, ensuring stable charging. Simultaneously, it also facilitates the receiving coil 32 contacting or approaching the transmitting coil, thereby better acquiring magnetic field energy.

[0045] In some embodiments, the wireless charging assembly 30 further includes an end cap 31 with an opening 311. The receiving coil 32 and the charging module 33 are both disposed within the end cap 31, and one end of the end cap 31 with the opening 311 is sleeved onto one end of the battery assembly 20. Thus, the end cap 31 stably fixes the wireless charging assembly 30 to the battery assembly 20, improving structural stability. Simultaneously, by placing the receiving coil 32 and the charging module 33 within the end cap 31, the receiving coil 32 and the charging module 33 are effectively protected, thereby achieving better waterproof and dustproof effects.

[0046] It should be noted that one end of the end cap 31 is an opening 311, allowing one end of the end cap 31 to be fitted onto one end of the battery assembly 20, ensuring that the wireless charging assembly 30 is stably fixed to the battery assembly 20. The connection between the end cap 31 and the battery assembly 20 can be achieved in various ways, such as, but not limited to, snap-fit ​​or screw-fit.

[0047] Meanwhile, the end cap 31 can also have various shapes, such as, but not limited to, cylindrical, quadrangular prism, spherical, etc.

[0048] Furthermore, one end of the battery assembly 20 is provided with a connecting ring 23, and the end of the end cap 31 with an opening 311 is fitted onto the connecting ring 23. Therefore, during assembly, the end of the end cap 31 with an opening 311 can be fitted onto the outside of the connecting ring 23, so that the end cap 31 is stably attached to the connecting ring 23, thereby improving the connection stability between the battery assembly 20 and the end cap 31.

[0049] The connection method between the connecting ring 23 and the battery module 20 can be, but is not limited to, bolt connection, snap-fit, riveting, welding, or bonding. Alternatively, the connecting ring 23 can be an integral part of the battery module 20's housing, for example, by injection molding, die casting, or extrusion.

[0050] In some embodiments, the wireless charging assembly 30 further includes a first sealing ring 233 and a second sealing ring 234. The connecting ring 23 has an external thread 232. The first sealing ring 233 and the second sealing ring 234 are respectively sleeved on the outside of the connecting ring 23 and located on opposite sides of the external thread 232. The end cap 31 has an internal thread 312 on its inner wall. The end cap 31 is sleeved on the outside of the connecting ring 23, and the internal thread 312 is screwed into the external thread 232. Thus, the engagement of the external thread 232 and the internal thread 312 allows the end cap 31 to be quickly and stably fixed onto the connecting ring 23. Simultaneously, the first sealing ring 233 and the second sealing ring 234, respectively located on opposite sides of the external thread 232, ensure that while the end cap 31 is screwed onto the connecting ring 23, the first sealing ring 233 and the second sealing ring 234 seal between the inner wall of the end cap 31 and the connecting ring 23, improving the sealing performance between the end cap 31 and the connecting ring 23, which is beneficial for improving the sealing performance of the wireless thermometer.

[0051] It should be noted that, to ensure the first sealing ring 233 and the second sealing ring 234 are stably mounted on the connecting ring 23, two annular grooves 231 located on both sides of the external thread 232 can be provided on the connecting ring 23. The first sealing ring 233 and the second sealing ring 234 are respectively disposed in the two annular grooves 231. The materials of the first sealing ring 233 and the second sealing ring 234 can be, but are not limited to, glue, rubber, etc.

[0052] In some embodiments, the battery assembly 20 includes a battery 21 and a housing 22, with the battery 21 disposed within the housing 22, and the wireless charging assembly 30 and the wireless thermometer body 10 both disposed within the housing 22. Thus, the housing 22 provides protection for the battery 21, ensuring its stable operation.

[0053] It should be noted that there are various ways to connect the housing 22 and the wireless charging component 30, such as, but not limited to, threaded connection, snap-fit, riveting, welding, bolt connection, and bonding.

[0054] In some specific examples, the housing 22 has a connecting ring 23 at one end along its own axis, and the end cap 31 of the wireless charging component 30 is sleeved on the connecting ring 23.

[0055] In some embodiments, a temperature detection system includes: a transmitter including a transmitting coil; and a wireless thermometer for brewing, such as any of the above, wherein a receiving coil 32 is matched with the transmitting coil.

[0056] The aforementioned temperature detection system employs the wireless thermometer used in brewing. A wireless charging component 30 is integrated into the battery assembly 20. A receiving coil 32 receives the magnetic energy from the transmitting coil and couples it to the charging module 33. The charging module 33 then converts the AC signal into DC power and supplies this power to the battery assembly 20 for charging. This eliminates the need for a charging cable, making the wireless thermometer more flexible and convenient to use, reducing operational complexity and safety hazards. Furthermore, the wireless charging component 30 enables wireless charging of the thermometer body 10, preventing damage to the charging interface caused by frequent plugging and unplugging, thus improving the durability and reliability of the wireless thermometer.

[0057] It should be noted that a transmitter is a device capable of generating magnetic field energy. Besides a transmitting coil, it may also include control circuits such as an MCU circuit, an H-bridge circuit, a code transmission circuit, and a decoding circuit. During charging, the transmitting coil generates an alternating magnetic field through the control circuit. When the wireless charging component 30 is placed on the transmitter, this magnetic field induces a current in the receiving coil 32, thereby achieving wireless power transmission. The control circuit is responsible for adjusting the transmission power to ensure the safety and efficiency of the charging process. Specifically, the control circuit ensures that the transmitter and the wireless charging component 30 can communicate normally, match the charging protocol, and achieve power transmission.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
