Description

Technical Field

[0001] This application relates to the technical field of temperature measuring instruments, and in particular to a wireless temperature measuring instrument. Background Technology

[0002] In fields such as food cooking and industrial processing, accurate temperature measurement is crucial for ensuring product quality, safety, and process control.

[0003] Currently, while wireless temperature probes on the market offer convenience due to their wireless connectivity, their probe tubes typically have limited temperature measurement ranges, generally not exceeding 120 degrees Celsius. This temperature range is unsuitable for measuring oil temperatures in high-temperature cooking scenarios such as frying (which can typically reach 180 degrees Celsius or even higher), severely limiting the application of these probes in high-temperature measurements.

[0004] In addition, most existing oil temperature probes capable of measuring higher temperatures are handheld probes. Although these probes can withstand higher temperatures and meet the needs of high-temperature and oil temperature measurement, they do not have wireless connectivity. This means that users must connect the probe to the display device via a wired connection during use. This is not only inconvenient to operate, but the presence of the cable also restricts the user's range of motion. In some complex cooking or processing environments, the cable may also pose safety hazards such as tangling and pulling, affecting the flexibility and efficiency of the measurement.

[0005] Regarding the aforementioned technologies, the inventors believe that existing wireless temperature probes have limitations in temperature measurement range. Oil temperature probes capable of measuring higher temperatures must be connected to the display device via a wired connection, which is inconvenient to operate. Furthermore, the presence of cables restricts the user's range of movement, affecting the flexibility and efficiency of measurement. Utility Model Content

[0045] This application discloses a wireless temperature measuring device, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The wireless temperature measuring instrument includes an oil temperature probe module 1, a wireless temperature probe module 2, and a connection module 3. The oil temperature probe module 1 includes a first housing 11, in which a temperature measuring element 12 is installed.

The power block 221 is electrically connected to the PCB board 222, and the PCB board 222 is communicatively connected to a mobile terminal.

[0046] The connecting module 3 includes a first sleeve 31 and a second sleeve 37. The first sleeve 31 is coaxially sleeved outside one end of the first housing 11. One end of the second sleeve 37 is coaxially sleeved inside the first sleeve 31, and the other end is coaxially sleeved inside the handle 21. The second housing 22 is coaxially sleeved inside the second sleeve 37. A connecting plate 33 is installed inside the first sleeve 31. One side of the connecting plate 33 is connected to the temperature sensing element 12, and the other side is provided with an elastic pin 331. A mounting base 34 is provided between the connecting plate 33 and the second sleeve 37. A connecting wire 35 is provided inside the mounting base 34. One end of the connecting wire 35 is connected to the elastic pin 331, and the other end passes through and extends out of the mounting base 34. The connecting wire 35 is communicatively connected to the PCB board 222.

[0047] In the wireless thermometer, the first housing 11 of the oil temperature probe module 1 is used to protect the temperature sensing element 12 and prevent the temperature sensing element 12 from being affected by external environmental factors. The temperature sensing element 12 is used to sense the temperature change of the object being measured, such as oil temperature, and convert the temperature change into an electrical signal.

[0048] The handle 21 in the wireless temperature probe module 2 provides a handheld part, making it convenient for users to operate and control the thermometer during temperature measurement. At the same time, it also provides a certain degree of protection for the internal components such as the second housing 22. The second housing 22 is used to house important electronic components such as the power block 221 and the PCB board 222, protecting and fixing these components to ensure their stability during operation. The power block 221 provides power support for the entire thermometer, ensuring that electronic components such as the PCB board 222 and the connecting wires 35 can work normally. The PCB board 222 integrates various circuits and electronic components, which are responsible for processing, converting and transmitting the electrical signals from the temperature measuring element 12. At the same time, it establishes a communication connection with the mobile terminal and sends the processed temperature data to the mobile terminal, so that users can view the measured temperature information in real time.

[0049] In the connection module 3, the first sleeve 31 connects the first housing 11 of the oil temperature probe module 1 to the connection module 3, which serves to position and fix the module. The second sleeve 37 connects the handle 21 to the first sleeve 31 and the second housing 22, so that the oil temperature probe module 1 and the wireless temperature probe module 2 are reliably connected together on the same axis, ensuring the relative position between the two modules is stable. At the same time, the first sleeve 31 can protect the internal connection plate 33.

[0050] The connecting plate 33 acts as a bridge for signal transmission, ensuring accurate and reliable transmission of temperature signals and preventing signal loss or interference. The electrical signal generated by the temperature sensing element 12 is transmitted to the elastic pin 331, enabling the transmission of temperature signals from the oil temperature probe module 1 to the subsequent wireless temperature probe module 2 communication link. The elastic pin 331 then transmits the signal from the temperature sensing element 12 on one side of the connecting plate 33 to the connecting wire 35. The elasticity of the elastic pin 331 allows it to adapt to a certain degree of vibration, displacement, and thermal expansion and contraction. The elastic pin 331 ensures stable signal transmission between the temperature sensing element 12 and the connecting wire 35, maintaining a good electrical connection even during operation of the thermometer under conditions of vibration or minor component displacement, preventing signal interruption or poor contact, and improving the stability and reliability of the entire temperature measurement system.

[0051] The mounting base 34 serves to fix and support the connecting wire 35, providing a stable installation position for the connecting wire 35. This ensures that the connecting wire 35 maintains the correct posture and position during the operation of the thermometer, without displacement or shaking, thus guaranteeing stable signal transmission and reception performance. The connecting wire 35 converts the temperature electrical signal transmitted from the temperature sensing element 12 through the elastic pin 331 into a radio electromagnetic wave signal and sends it out. At the same time, it can also receive wireless signals from other devices (such as mobile terminals), realizing two-way communication and achieving temperature data transmission.

[0052] Connecting wire 35 is communicatively connected to PCB board 222. PCB board 222 processes the temperature signal transmitted from connecting wire 35, converting it into a digital signal format suitable for mobile terminal reception and processing. PCB board 222 also establishes a communication connection with the mobile terminal, sending and receiving data according to a certain communication protocol. The mobile terminal receives the temperature data sent from PCB board 222 and presents it to the user in an intuitive way (such as digital display, chart display, etc.) for easy viewing and analysis of temperature information. Simultaneously, the user can set various parameters through the mobile terminal, such as temperature alarm threshold and measurement cycle, and send these commands to the PCB board to achieve remote control of the temperature measurement system.

[0053] This wireless thermometer accurately measures the temperature of the object being measured, including objects with high temperatures (above 120 degrees Celsius), such as oil. The wireless temperature probe module 2 handles data processing and wireless transmission, while the connection module 3 ensures stable connection and signal transmission for all components. The entire device can accurately measure the temperature of objects, including those at high temperatures, in real time and wirelessly transmit the data to a mobile device for convenient real-time viewing and monitoring of oil temperature. This thermometer solves the problems of limited measurement range (e.g., above 120 degrees Celsius) and inconvenient connection associated with traditional temperature probes, improving the efficiency and convenience of temperature measurement in high-temperature oil. It is suitable for various cooking and industrial processing scenarios, especially high-temperature cooking scenarios such as frying where precise oil temperature measurement is crucial.

[0054] refer to Figure 3 , Figure 4 and Figure 7 A positioning seat 32 is provided inside the first sleeve 31, and a second sleeve 37 is installed on one side of the positioning seat 32.

One end of the elastic pin 331 is installed on the connecting plate 33, and the other end passes through the through hole 321 and is connected to one end of the connecting wire 35. The positioning seat 32 provides an installation base for the connecting plate 33 and the second sleeve 37. The through hole 321 on the positioning seat 32 provides a channel for the elastic pin 331, ensuring the accuracy of the position of the elastic pin 331 on the connecting plate 33 and the connecting wire 35, so that the elastic pin 331 can accurately connect the connecting plate 33 and the connecting wire 35, thus establishing a reliable path for signal transmission.

[0055] refer to Figure 5 An insulating block 341 is provided at one end of the mounting base 34 near the positioning base 32. The insulating block 341 has a first mounting hole 3411. The connecting wire 35 is installed in the first mounting hole 3411. The insulating block 341 serves as electrical isolation, preventing the connecting wire 35 from making electrical contact with potentially live components, thus avoiding short circuits and other faults. It also ensures that the signal transmitted by the connecting wire 35 is not subject to other electrical interference. Furthermore, the first mounting hole 3411 on the insulating block 341 provides a precise installation position for the connecting wire 35. The insulating block 341 ensures the stability and reliability of the connecting wire 35's operation, improves the quality of signal transmission, and prevents temperature data transmission errors or malfunctions of the wireless thermometer due to electrical problems.

[0056] An insulating block 341 has a second mounting hole 3412, and a mounting plate 36 is disposed within the second mounting hole 3412. One end of the mounting plate 36 is connected to an antenna plate 361, and a connecting wire 35 is disposed on the antenna plate 361. One end of a PCB board 222 is connected to the antenna plate 361, and the other end is connected to a power supply block 221, which is located at the end of the second housing 22. The second mounting hole 3412 provides a mounting position for the mounting plate 36, determining its specific position on the insulating block 341. One end of the mounting plate 36 is connected to the antenna plate 361, serving to connect and support the antenna plate 361, stably fixing the antenna plate 361 to the insulating block 341, and also providing a support structure for the connecting wire 35 on the antenna plate 361. 361 is used to install the connecting wire 35, providing a stable installation platform for the connecting wire 35 and ensuring the stability of the connecting wire 35 during use. The antenna board 361 is connected to one end of the PCB board 222 to further position the PCB board 222 and ensure smooth signal transmission. The antenna board 361 is equipped with an antenna, which is a key component for signal transmission and is connected to the PCB board 222. The temperature electrical signal processed by the PCB board 222 is converted into a radio electromagnetic wave signal. It can also receive wireless signals sent from the mobile terminal, thereby enabling wireless transmission and remote control. This realizes communication between the temperature signal transmitted by the connecting wire 35 and the PCB board 222, and transmits the temperature information to the mobile terminal, improving the reliability of temperature data transmission.

[0057] refer to Figure 6 and Figure 8 The PCB board 222 has a first connecting groove 2221 at one end, and the end of the antenna board 361 is installed in the first connecting groove 2221. The PCB board 222 has second connecting grooves 2222 on both sides. The second connecting grooves 2222 are fitted with clamping members 223 to fix the PCB board 222 in the second housing 22. The first connecting groove 2221 is used to accommodate the end of the antenna board 361, providing a precise docking position for the antenna board 361 and the PCB board 222, realizing a tight connection between the two, and ensuring that the signal received by the connecting wire 35 can be stably transmitted to the PCB board.

[0058] The second connecting groove 2222 provides installation space for the clamping member 223. By cooperating with the clamping member 223, the PCB board 222 is fixed inside the second housing 22, preventing displacement or shaking of the PCB board 222 during the operation of the wireless temperature measuring instrument. The clamping member 223 applies pressure to the PCB board 222 within the second connecting groove 2222, ensuring it fits tightly against the inner wall of the second housing 22, thereby fixing the PCB board 222 in a predetermined position. This effectively prevents the PCB board 222 from shaking or shifting within the second housing 22, ensuring stable circuit connections on the PCB board 222, guaranteeing its normal processing of temperature signals and wireless communication, and preventing malfunctions of the wireless temperature measuring instrument due to a loose PCB board 222.

[0059] A control component is mounted on the PCB board 222. This component communicates with the mobile device and processes the temperature signal transmitted from the temperature sensing element 12 via the connecting wire 35, converting it into a format recognizable by the mobile device. Furthermore, it maintains a bidirectional communication connection with the mobile device, receiving control commands such as calibration and measurement mode switching commands. Simultaneously, it sends the processed temperature data to the mobile device in real time. This control component enables intelligent processing of temperature data and remote control of the mobile device. Users can conveniently obtain temperature data via the mobile device and flexibly adjust the device's operating mode according to actual needs, greatly improving the practicality and user experience of the wireless thermometer.

[0060] In addition, a first sleeve 38 is fitted onto one end of the second sleeve 37, and a second sleeve 39 is fitted onto the other end. A mounting base 34 is installed inside one end of the first sleeve 38, and the second sleeve 37 is coaxially installed on the other end of the mounting base 34. The first sleeve 38 is fitted inside the first sleeve 31, and one end of the second sleeve 39 is fitted outside the second sleeve 37, and the other end is fitted outside the second housing 22. The first sleeve 38 provides an installation position for the mounting base 34, which is installed inside one end. The first sleeve 38 connects the second sleeve 37 and the first sleeve 31, enhancing the tightness and stability of the connection between the two, and also providing a certain degree of protection and fixation for the mounting base 34.

[0061] The second connector 39 tightly connects the second sleeve 37 to the second housing 22, further enhancing the connection stability between the wireless temperature probe module 2 and the connection module 3. It also protects and positions the internal components, strengthens the structural stability of the entire wireless thermometer, ensures that the relative positions between the wireless temperature probe module 2 and the connection module 3 are fixed, and prevents the components from loosening or shifting due to vibration, collision or other factors during use, thus ensuring the reliability of the collaborative work of all components.

[0062] refer to Figure 9 The handle 21 is provided with a first placement cavity 211 for installing the second housing 22 and a second placement cavity 212 for installing the second sleeve 37 and the second connector 39. The first placement cavity 211 and the second placement cavity 212 are connected. The second housing 22 is coaxially sleeved in the second sleeve 37. The first placement cavity 211 is used to install the second housing 22, providing a precise installation space for the second housing 22 and determining its position in the handle 21. At the same time, it plays a role in protecting the power block 221 and PCB board 222 and other electronic components inside the second housing 22, and aligning the wireless temperature measuring instrument for stable operation.

[0063] The second placement cavity 212 provides an installation position for the second sleeve 37 and the second connector 39, allowing them to form a tight connection with the handle 21. The communication between the first placement cavity 211 and the second placement cavity 212 ensures a smooth connection between the second sleeve 37 and the second housing 22, thereby ensuring the coordinated operation of the entire wireless temperature probe module 2 and the connection module 3, and preventing the transmission of temperature signals and the overall performance of the wireless thermometer from being affected by loose components.

[0064] The implementation principle of a wireless thermometer according to an embodiment of this application is as follows: When the wireless thermometer is used to measure the temperature of an object (such as oil), the temperature sensing element 12 inside the first housing 11 can sensitively sense the temperature change of the object (such as oil) and convert this temperature change into a corresponding electrical signal. These electrical signals are transmitted to the elastic pin 331 through the connecting plate 33. Since the connecting plate 33 is installed inside the positioning seat 32, the positioning seat 32 provides a precise installation position and connection reference for each component, ensuring the stability of the signal transmission path. The elastic pin 331 transmits the signal to the metal contact of the connecting wire 35 installed in the first mounting hole 3411 of the insulating block 341. The insulating block 341 plays an electrical isolation role, preventing signal interference and ensuring that the connecting wire 35 can stably receive signals.

[0065] After receiving the signal, the connecting wire 35 transmits it to the PCB board 222. The control component on the PCB board 222 processes the received signal and converts it into a temperature data format that can be recognized by the mobile terminal. The processed temperature data is transmitted in real time to the user's mobile device through the communication connection established between the control component, the antenna of the antenna board 361, and the mobile terminal. The user can conveniently view the data of the measured object (such as oil temperature) on the mobile terminal, and can also adjust the working mode of the device through the control component according to actual needs to complete the accurate measurement and real-time monitoring of the measured object.

[0066] This wireless thermometer can accurately measure objects, including those at high temperatures, solving the problems of limited measurement range (above 120 degrees Celsius) and inconvenient connection of traditional temperature probes. It improves the efficiency and convenience of temperature measurement in high-temperature oil probes and is suitable for various cooking and industrial processing scenarios, especially high-temperature cooking scenarios such as frying where oil temperature measurement is critical.

[0067] During this process, the power supply block 221 provides stable power support for the entire wireless temperature measuring instrument, ensuring that all components work normally.
