DETAILED DESCRIPTION

[0047] The present application is further described in detail below in conjunction with the accompanying drawings.

[0048] In one embodiment, if Figure 1-Figure 8 As shown, the present application discloses a wireless temperature probe charging system, which specifically includes the following steps:

[0049] A wireless temperature probe charging system includes a probe body 1 and a charging relay box 2 detachably connected to the probe body 1. The probe body 1 is provided with a first wireless charging component 3 and a sealing structure for sealing the first wireless charging component 3. The charging relay box 2 is provided with a second wireless charging component 4 that establishes a near-field communication path with the first wireless charging component 3, a power supply module 6 and a control module 5. The control module 5 is used to control the power supply module 6 to adaptively supply power to the probe body 1 through the near-field communication path.

[0050] In this embodiment, the wireless temperature probe, i.e., the probe body 1, is charged by means of a wireless near-field connection. The wireless charging method solves the problem of poor contact in existing charging methods and is more stable for long-term use. The charging coil of the wireless temperature probe, i.e., the first wireless charging component 3, can be used as a Bluetooth antenna, and there is no need to design other antennas. According to the sealing structure design of the new probe, it can be coupled with the charging relay box 2 in a variety of ways to perform wireless charging and communication data interaction. The key innovation of this application is to use a near-field wireless charging solution to replace the existing shrapnel contact charging solution. It is no longer necessary to form a charging circuit through physical contact, and isolated non-contact charging can be achieved, thereby perfectly solving the problems of the existing shrapnel contact charging solution, saving the shrapnel holder, and optimizing the structure. The temperature measuring probe can be completely sealed, thereby effectively solving the sealing problem, and can be completely waterproof and oil-proof. The temperature measuring probe can be completely sealed, thereby isolating the static electricity introduction channel, which can effectively solve the problem of static electricity interference.

[0051] Preferably, the near-field wireless charging solution can be NFC wireless charging technology, which uses a radio frequency of 13.56MHz to perform close-range communication and power transmission between the relay box and the probe. The charging relay box 2 serves as the NFC power transmitter (i.e., WLC-P), and the probe body 1 serves as the power receiver (i.e., WLC-L). The basic principle of power transmission between the two is near-field magnetic induction; and some models of NFC wireless charging chips can be: 1) NXP's transmitter chip CTN730, and the receiving chip CRN120; 2) ST's transmitter chip ST25R3916B, and the receiving chip ST25DV04KC; 3) Rohm's transmitter chip ML7631 / ML7671, and the receiving chip ML7630 / ML7670; 4) Renesas's transmitter chip PTX130W, and the receiving chip PTX30W.

[0052] Preferably, the near-field magnetic induction technology shows its unique advantages in the case of the above-mentioned probe body 1 and the charging relay box 2. First, it can achieve efficient energy transmission. Since a strong magnetic field is established between the coil in the charging relay box 2 and the coil on the probe body 1, the energy loss during the transmission process is reduced to a minimum, thereby ensuring the high efficiency of the charging process. Secondly, the near-field magnetic induction technology has excellent safety. It does not generate any electromagnetic radiation and does not pose any potential health risks to the human body or the surrounding environment. In addition, due to the high intensity of the magnetic field and the limited range of action, energy transmission will only occur when the probe body 1 is very close to the charging relay box 2, so interference with other equipment or personnel can be effectively avoided. Finally, the near-field magnetic induction technology also has excellent stability and reliability, can adapt to various complex usage environments, and ensure the continuous and stable power supply of the probe body 1.

[0053] In summary, the present application charges by means of a wireless near-field connection. The wireless charging method solves the problem of poor contact in existing charging methods and is more stable for long-term use. The traditional wired charging method requires the charger to be physically connected to the device, which may cause poor contact due to loose interfaces, oxidation or other reasons, thereby affecting the charging effect. The wireless charging solution replaces the existing spring contact charging solution, and there is no longer a need to form a charging circuit by physical contact. The near-field wireless charging solution can be an NFC wireless charging solution, which can achieve isolated contactless charging and prevent poor contact due to wear. In addition, the sealing structure of the probe body 1 that seals the first wireless charging component 3 can effectively solve the problem of poor sealing of traditional charging devices, and can be completely waterproof and oil-proof. At the same time, it also isolates the static electricity introduction channel, which can effectively solve the problem of static electricity interference.

[0054] In one embodiment, in addition to the NFC wireless charging solution, the near-field wireless charging solution may also include magnetic induction wireless charging (such as the Qi standard) and magnetic resonance wireless charging. These solutions use electromagnetic fields to transmit energy over a short distance to achieve contactless charging between devices. Magnetic induction technology is usually used for small devices such as mobile phones and smart watches, while magnetic resonance technology can charge over a relatively large distance and support charging multiple devices at the same time.

[0055] Further, such as Figure 1 , Figure 3 As shown, the charging relay box 2 includes a first upper shell 211 and a first lower shell 212, and a receiving cavity is provided in the first upper shell 211 and the first lower shell 212. The first upper shell 211 is provided with a first through hole 214 connected to the receiving cavity, and a probe sleeve 213 is provided in the receiving cavity. The pipe mouth of the probe sleeve 213 is arranged corresponding to the first through hole 214 so that the probe sleeve 213 can be movably sleeved and matched with the probe body 1. The second wireless charging component 4 includes a second charging coil 41 sleeved on the probe sleeve 213.

[0056] In this embodiment, the charging relay box 2 is composed of a first upper shell 211 and a first lower shell 212, and a receiving chamber is provided inside for receiving the probe body 1 and related electronic components. A through hole is provided on the first upper shell 211, which is connected to the receiving chamber for inserting and removing the probe body 1. A probe sleeve 213 is provided in the receiving chamber, and the nozzle of the probe sleeve 213 is arranged corresponding to the first through hole 214, so that the probe body 1 can be movably sleeved on the probe sleeve 213, thereby realizing the detachable connection between the probe body 1 and the charging relay box 2. The second wireless charging component 4 includes a second charging coil 41, which is sleeved on the probe sleeve 213 and corresponds to the wireless charging component on the probe body 1. When the probe body 1 is inserted into the charging relay box 2, the wireless charging component on the probe body 1 is opposite to the second charging coil 41, and wireless charging is realized through the principle of near-field magnetic induction. The wireless charging component on the probe body 1 converts electrical energy into a magnetic field, and the second charging coil 41 converts the magnetic field into electrical energy, thereby charging the probe body 1. During the whole process, there is no direct physical contact between the probe body 1 and the charging relay box 2, thus avoiding problems such as poor contact and improving the stability and reliability of charging.

[0057] Preferably, the ceramic handle and metal needle tube of the wireless temperature probe are connected into a whole by glass sintering (or brazing), so that the waterproof sealing will be better. After the inner parts are installed, the middle of the metal needle tube is welded together by laser welding. The weld position is the laser welding ring safety line 8 position of the temperature probe; the charging box is designed with a battery (lithium battery or dry battery) to charge the temperature probe through the above-mentioned wireless charging method.

The first handle 111 includes a first handle 1111 which is sleeved with the probe sleeve 213, and a first sealing part 1112 which is smaller in diameter than the first handle 1111. The first sealing ring 112 is sleeved on the first sealing part 1112. On the sealing part 1112, the tail of the first needle tube 113 is sleeved on the first sealing ring 112, and a recessed hole 1113 is provided on the inner side of the first handle 1111, and the recessed hole 1113 penetrates the first sealing part 1112 in the direction close to the first sealing part 1112, so that the tail of the first internal component 114 and the first charging coil 31 are inserted into the recessed hole 1113, and a sealing structure for sealing the first wireless charging component 3 is formed between the first handle 111, the first sealing ring 112 and the first needle tube 113 by a glass sintering process or a metal brazing process.

[0059] In this embodiment, the probe body 1 is composed of a plurality of structural parts, including a first handle 111, a first sealing ring 112, a first needle tube 113 and a first internal component 114. Among them, the first handle 111 is used to hold the probe body 1, and has a first handle 1111 and a first sealing part 1112. The first handle 1111 cooperates with the probe sleeve 213 to realize the connection between the probe body 1 and the charging relay box 2. The diameter of the first sealing part 1112 is smaller than that of the first handle 1111, which is used to improve the sealing performance of the probe body 1. The first sealing ring 112 is sleeved on the first sealing part 1112 to further enhance the sealing performance of the probe body 1. The tail of the first needle tube 113 is sleeved on the first sealing ring 112 to fix the position of the first sealing ring 112. The first internal component 114 includes a first charging coil 31, which is sleeved on the tail of the first internal component 114 and corresponds to the second charging coil 41. The head of the first internal component 114 is inserted into the first needle tube 113 to fix the position of the first internal component 114. A recessed hole 1113 is provided on the inner side of the first handle 1111, and the recessed hole 1113 penetrates the first sealing part 1112, so that the tail of the first internal component 114 and the first charging coil 31 can be inserted into the recessed hole 1113. When the probe body 1 is inserted into the charging relay box 2, the first handle 1111 cooperates with the probe sleeve 213 to realize the connection between the probe body 1 and the charging relay box 2. At the same time, the first sealing part 1112, the first sealing ring 112 and the first needle tube 113 work together to form a sealing structure to prevent external liquid or gas from entering the interior of the probe body 1. The tail of the first internal component 114 and the first charging coil 31 are inserted into the recessed hole 1113, corresponding to the second charging coil 41, and wireless charging is realized through the principle of near-field magnetic induction. The electric energy is transmitted from the charging relay box 2 to the probe body 1, and the electronic components inside the probe body 1 are powered to realize the functions of the probe body 1. During the whole process, there is no direct physical contact between the probe body 1 and the charging relay box 2, which improves the stability of charging.

The second wireless charging component 4 includes a fourth charging coil 42, which is laid flat on the control module 5 and is used for magnetic induction coupling with the wireless charging component on the probe body 1. The magnetic field generated by the fourth charging coil 42 can penetrate the probe body 1 and interact with the wireless charging component inside it, thereby realizing wireless charging. Next to the fourth charging coil 42, a through hole is provided on the control module 5, which is used to make way for the first limiting groove 224. The first limiting groove 224 extends from the second upper shell 221 toward the through hole, and is used to limit the movement range of the probe body 1 in the charging relay box 2. When the probe body 1 is inserted into the charging relay box 2, its tail will contact the first limiting groove 224, thereby being restricted to a specific position. Through the linkage of these structural parts, the charging relay box 2 can stably fix the probe body 1 and perform efficient wireless charging with the wireless charging components inside it. At the same time, the presence of the first limiting groove 224 ensures that the probe body 1 will not move excessively or be misplaced during the charging process, thereby improving the reliability and accuracy of charging.

Through this connection method, the LDO unit converts the unstable voltage provided by the lithium battery unit into a stable operating voltage for use by the control module 5.

[0074] A dc-dc boost unit is provided between the wireless transmitter module 702 and the lithium battery unit. The model of the dc-dc boost unit is AP3012KTR-E1. AP3012KTR-E1 is a small and efficient DC-DC boost converter used to convert low voltage input such as lithium battery cells into the required higher voltage output.

[0075] In addition, the control module 5 is also connected to a TFT module and a 4-way touch button, and the control module 5 expands its functions by connecting the TFT module and the 4-way touch button. The TFT module, model MSP0963, also known as a thin film transistor liquid crystal display, is a common display device for displaying images and texts. It is usually composed of a liquid crystal panel and a drive circuit, wherein the liquid crystal panel is responsible for displaying images, and the drive circuit is responsible for controlling parameters such as brightness, contrast and color of the liquid crystal panel.

[0076] When an external 5V adapter is connected, the 5VUSB module supplies power to the entire charging relay box 2. When there is no external adapter, the 3.7V lithium battery supplies power to the entire charging relay box 2. The above situation is completed by the 5VUSB and 3.7V lithium battery power supply switching module 701.

[0077] In summary, the technical solution realizes adaptive power supply, wireless charging and data communication functions for the probe body 1 by setting a power switching module 701, a wireless transmission module 702 and a Bluetooth module 703 on the charging relay box 2 and the probe body 1, and setting a wireless receiving module 704 and a probe battery module 705 on the probe body 1, thereby improving the intelligence and reliability of the system.

[0078] like Fig.10 As shown, a charging method for a wireless temperature probe charging system is applied to a wireless temperature probe charging system, and the charging method includes:

[0079] S10, detect whether the probe body 1 is in place, if not, do not start wireless power transmission; in the present embodiment, whether the probe body 1 is in place refers to whether the probe body 1 is correctly inserted or placed in the charging relay box 2, so as to establish an effective wireless connection with the wireless charging component in the charging relay box 2. Not starting wireless power transmission means that if the probe body 1 is not correctly inserted or placed in the charging relay box 2, resulting in an inability to establish an effective wireless connection, then the charging relay box 2 will not start transmitting wireless power to the probe body 1, so as to avoid unnecessary energy loss and potential safety risks. In the above case, when the probe body 1 is inserted into the charging relay box 2, the system will first detect whether the probe body 1 is in place. If the probe body 1 is not correctly inserted or placed, resulting in an inability to establish an effective wireless connection with the wireless charging component in the charging relay box 2, then the system will not start wireless power transmission. This is because in the absence of an effective connection, wireless power transmission may result in a waste of energy and may even pose a safety risk to the device or user. Therefore, only after the probe body 1 is correctly inserted or placed in the charging relay box 2 and an effective wireless connection is established, the system will start wireless power transmission to ensure the safety, efficiency and reliability of the charging process.

[0080] S20, if so, then obtain the power information of the probe body 1, and determine whether to start charging according to the power information; in this embodiment, the power information refers to the current battery power status of the probe body 1, including the percentage of battery power, voltage value, etc., which is used to evaluate whether the probe body 1 needs to be charged and the urgency of charging. Starting charging means judging whether its battery power is lower than a preset threshold or is in a state of needing charging according to the power information of the probe body 1. If the conditions are met, the charging operation is started to ensure that the probe body 1 can work normally. In the above case, when the probe body 1 is correctly inserted into the charging relay box 2 and an effective connection is established, the system will obtain the power information of the probe body 1. According to the power information, the system will judge whether the probe body 1 needs to be charged. If the battery power of the probe body 1 is lower than the preset charging threshold or is in a state of needing charging, the system will decide to start charging. After starting charging, the system will control the wireless charging component in the charging relay box 2 to start transmitting wireless power to the probe body 1. At the same time, the system will also intelligently adjust the charging parameters, such as charging current and charging voltage, according to the power information and charging requirements of the probe body 1 to ensure the safety, efficiency and reliability of the charging process. In this way, the probe body 1 can obtain the required electrical energy in time and maintain a good working state.

[0081] S30. If the charging mode needs to be started, the charging mode is determined, and the charging mode includes a negotiated charging mode and a static charging mode. In this embodiment, the charging mode refers to the charging method or strategy selected by the system according to the power information and charging requirements of the probe body 1. It includes two types: a negotiated charging mode and a static charging mode. In the above case, when the system determines that the probe body 1 needs to be charged, it will select a suitable charging mode according to the specific situation. If the negotiated charging mode is selected, the system will communicate with the probe body 1 to obtain its current power information, charging requirements and other related parameters. Then, the system will intelligently adjust the charging parameters, such as charging current and charging voltage, based on this information to achieve efficient and safe charging. If the static charging mode is selected, the system will charge according to the preset charging parameters without communicating with the probe body 1 or adjusting the charging parameters. Regardless of which charging mode is selected, the goal of the system is to ensure that the probe body 1 can obtain the required power in a timely manner and maintain a good working condition. By intelligently selecting and adjusting the charging mode, the system can improve charging efficiency, extend battery life, and provide a better user experience.

[0082] S40, if it is determined that the charging mode is a static charging mode, wireless power transmission is performed according to the power level within the standard range; in this embodiment, the static charging mode refers to a charging mode in which the system charges according to preset charging parameters, and does not dynamically adjust according to the real-time power information or charging demand of the probe body 1. In the above case, if the system determines that the charging mode is a static charging mode, it will perform wireless power transmission according to the power level within the preset standard range. This means that the system will charge the probe body 1 with a fixed charging current and charging voltage, and will not adjust according to its current power state or charging demand. This charging method is suitable for situations where charging efficiency is not required or fast charging is required. However, the static charging mode also has some disadvantages. Since it does not consider the real-time power information or charging demand of the probe body 1, it may result in low charging efficiency or unnecessary pressure on the battery. Therefore, in actual applications, the system usually selects a suitable charging mode according to the specific situation to achieve efficient and safe charging. In short, in the static charging mode, the system will perform wireless power transmission according to the preset power level to provide the probe body 1 with fixed current and voltage charging. This charging method is simple and direct, but may not achieve the best charging effect.

[0083] S50. If the charging mode is determined to be the negotiated charging mode, the wireless power transmission parameters are determined according to the data transmission between the probe body 1 and the control module 5. The wireless power transmission parameters include power level parameters and charging duration parameters. The wireless power transmission parameters are used to perform the wireless charging operation between the probe body 1 and the control module 5. In this embodiment, the power level parameter refers to the parameter used to control the power size during the wireless power transmission process, which determines the charging current and charging speed during the charging process. The charging duration parameter refers to the parameter used to control the duration of the charging process, which determines the end time of the charging process. The wireless charging operation refers to the process of transmitting electrical energy from the charging relay box 2 to the probe body 1 by wireless means. In this process, the wireless charging component in the charging relay box 2 generates a magnetic field and interacts with the wireless charging component on the probe body 1, thereby realizing the wireless transmission of electrical energy. In the above case, if the system determines that the charging mode is the negotiated charging mode, it will determine the wireless power transmission parameters according to the data transmission between the probe body 1 and the control module 5. Specifically, the probe body 1 will send its current power information and charging requirements to the control module 5, and the control module 5 will calculate the appropriate power level parameters and charging duration parameters based on this information to ensure the safety, efficiency and reliability of the charging process. Then, the control module 5 will send these parameters to the charging relay box 2 to guide the wireless charging operation. During the wireless charging operation, the wireless charging component in the charging relay box 2 will generate a corresponding magnetic field according to the power level parameters, and interact with the wireless charging component on the probe body 1 to transfer electrical energy to the battery of the probe body 1. At the same time, the system will control the duration of the charging process according to the charging duration parameters to ensure that the probe body 1 can obtain enough electrical energy but will not be overcharged. By negotiating the charging mode and intelligently adjusting the wireless power transmission parameters, the system can achieve efficient and safe charging and maximize the battery life of the probe body 1.

[0084] Step S50 may include the following steps: obtaining the body temperature change information in real time, and determining the charging adjustment parameters according to the body temperature change information; and monitoring the temperature change of the probe body 1 in real time by integrating a temperature sensor on the probe body 1. Temperature is one of the important factors affecting the charging efficiency and life of the battery, so the charging parameters need to be adjusted according to the temperature change;

[0085] Preferably, when the temperature of the probe body 1 is high, the following measures can be taken to adjust the charging parameters: Reduce the charging current: The increase in temperature will cause the chemical reaction rate inside the battery to accelerate. If a higher charging current is continued, the battery temperature may be further increased, and even the risk of overheating may be caused. Therefore, the charging current can be appropriately reduced to slow down the charging speed and avoid further temperature increase. Extend the charging time: Since the charging current is reduced, the charging time will be correspondingly extended. However, this can better control the battery temperature and avoid the risk of overheating, and it is also beneficial to extend the battery life. Increase the cooling time: During the charging process, the cooling time can be increased to allow the battery enough time to dissipate heat. For example, a cooling time interval can be inserted during the charging process, or the cooling operation can be continued after the charging is completed. Adjust the charging voltage: According to the change in temperature, the charging voltage can be appropriately adjusted. For example, when the temperature is high, the charging voltage can be appropriately reduced to reduce the chemical reaction rate inside the battery, thereby reducing the temperature. Use a temperature compensation algorithm: According to the change in temperature, a temperature compensation algorithm is used to automatically adjust the charging parameters. For example, when the temperature rises, the algorithm automatically reduces the charging current or extends the charging time to control the battery temperature. Through these measures, the charging parameters can be dynamically adjusted according to the temperature change of the probe body 1, so as to achieve efficient and safe charging and extend the battery life.

[0086] Obtain environmental monitoring information, and determine charging adjustment parameters based on the environmental monitoring information: Obtain the use environment information of the probe body 1, such as humidity, air pressure, etc., through external sensors or user input. These environmental factors will also affect the charging efficiency and life of the battery, so it is necessary to adjust the charging parameters according to changes in the environment; in the wireless temperature probe charging system, the acquisition of environmental monitoring information is crucial to optimizing the charging process. By real-time monitoring of parameters such as ambient temperature, humidity, air pressure, and light intensity, the system can determine the charging adjustment parameters based on this information to ensure the safety, efficiency, and reliability of the charging process. For example, when the ambient temperature is high, the system can automatically reduce the charging current to avoid overheating of the battery; when the ambient humidity is high, the system can automatically reduce the charging voltage to ensure the safety of the charging process; when the ambient air pressure is low, the system can automatically increase the charging current to speed up the charging speed; when the ambient light intensity is high, the system can automatically reduce the charging current to ensure the safety and efficiency of the charging process. Through this adaptive charging adjustment strategy, the system can maximize the charging efficiency, extend the battery life, and provide a better user experience.

[0087] Obtain charging history data, compare the charging history data with the wireless power transmission parameters, and determine the charging strategy; record environmental monitoring information during the charging process, and determine charging adjustment parameters based on the environmental monitoring information to achieve a more intelligent and efficient charging strategy; record the parameter settings, charging process, and charging results of each charging, and analyze and summarize them. Based on the analysis results, optimize the adjustment strategy of charging parameters to improve charging efficiency and extend battery life.

[0088] In this embodiment, in the wireless temperature probe charging system, obtaining charging history data is an important step in optimizing the charging strategy. By recording the wireless power transmission parameters during each charging process, such as charging current, charging voltage, charging time, etc., the system can establish a charging history database. Then, the system can compare and analyze the current wireless power transmission parameters with the charging history data regularly or when switching the charging mode.

[0089] For example, if the system finds that reducing the charging current in a high temperature environment can effectively prevent the battery from overheating, then the next time you charge, if the ambient temperature is high, the system can automatically adjust the charging current to avoid the risk of overheating. Similarly, if the system finds that increasing the charging voltage in a low temperature environment can speed up the charging speed, then the next time you charge, if the ambient temperature is low, the system can automatically adjust the charging voltage to shorten the charging time. By comparing and analyzing the charging history data and the current wireless power transmission parameters, the system can continuously learn and improve the charging strategy, improve the charging efficiency, extend the battery life, and provide a better user experience. At the same time, this also helps the system to achieve efficient and safe charging in different charging scenarios, such as high temperature, low temperature, high humidity and other environments. Through the above steps, a negotiated charging mode that is adaptively adjusted according to factors such as the temperature of the probe body 1 and the use environment can be realized, thereby improving the charging efficiency, extending the battery life, and ensuring the safety and reliability of the charging process.

[0090] In summary, the relay box will continuously monitor whether the probe is in place, and will not start wireless power transmission if the probe is not detected. After the relay box detects the probe, the wireless charging control phase begins, and the two devices negotiate the power level and charging duration requested for transmission. Once the information is agreed upon and the information exchange is completed, the wireless power transmission begins. The relay box transfers the agreed amount of power to the probe within the agreed duration. During this process, once it is detected that the probe is taken away or a foreign object is placed, the wireless power transmission will be stopped, and the foreign object detection (FOD) process will be performed during the entire power transmission duration. After the battery is fully charged, the probe will notify the relay box to stop the wireless power transmission. The relay box can perform repeated charging processes based on the voltage information fed back by the probe, and each charging process is a cycle. The charging method realizes intelligent and efficient charging of the probe body 1 by detecting whether the probe body 1 is in place, obtaining power information, determining the charging mode, and performing corresponding wireless power transmission operations according to different charging modes, thereby improving the accuracy and reliability of charging.

[0091] Further, such as Fig.11 As shown, during the wireless power transmission, an abnormal state detection step is performed simultaneously, and the abnormal state detection step includes:

[0092] S601, real-time detection of foreign body interference information, if detected, the charging relay box 2 is controlled to stop charging the probe body, if not detected, the detection is continued; in this embodiment, foreign body interference information refers to abnormal conditions that may affect the charging effect or safety during the charging process, such as metal objects approaching the charging relay box 2 or the probe body 1, the charging relay box 2 or the probe body 1 is blocked, etc. In the above case, the system will detect in real time whether there is foreign body interference information during the charging process. If foreign body interference information is detected, such as a metal object approaching the charging relay box 2 or the probe body 1, the system will immediately control the charging relay box 2 to stop charging the probe body 1 to avoid safety risks such as short circuit or overheating caused by contact between the metal object and the charging relay box 2 or the probe body 1. If no foreign body interference information is detected, the system will continue the charging operation and continue to monitor whether there are abnormal conditions during the charging process. By detecting foreign body interference information in real time and taking corresponding control measures in a timely manner, the system can effectively avoid safety risks during the charging process and ensure the safety and reliability of the charging process. At the same time, this also helps to extend the service life of the charging relay box 2 and the probe body 1, and improve the stability and durability of the entire wireless temperature probe charging system.

[0093] S602, real-time detection of whether the probe body is continuously in place, if so, continuous detection, if not, control the charging relay box 2 to stop charging the probe body. In this embodiment, whether the probe is continuously in place refers to whether the probe has been in the correct position and connection state during the charging process to ensure that the charging relay box 2 can normally transmit power to the probe. In the above case, the system will detect in real time whether the probe body is continuously in place. If the probe has been in the correct position and connection state during the charging process, the system will continue to perform charging operations and monitor whether other abnormal conditions occur during the charging process. If the probe is displaced, loosened, or loses connection with the charging relay box 2 during the charging process, the system will immediately control the charging relay box 2 to stop charging the probe to avoid the charging relay box 2 transmitting power to the wrong position or unconnected probe, thereby causing power waste or safety risks. By detecting whether the probe body is continuously in place in real time and taking corresponding control measures in time, the system can ensure the safety and reliability of the charging process, avoid power waste and potential safety risks. At the same time, this also helps to extend the service life of the charging relay box 2 and the probe, and improve the stability and efficiency of the entire wireless temperature probe charging system.
