Description

Technical Field

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

[0002] A wireless temperature probe is a device that combines wireless and temperature measurement technologies for temperature detection. As an advanced temperature measurement device, it offers advantages such as real-time monitoring, remote monitoring, temperature alarms, accuracy, reliability, convenience, and efficiency. Its wide range of applications and broad development prospects make wireless temperature probes an indispensable part of modern industrial production and technological development.

[0003] Utility model patent publication number CN220122100U discloses a novel Bluetooth temperature probe, including a needle tube, a handle, a first temperature sensor, a PCB board, and an antenna. The handle and needle tube are fixedly connected, and both the handle and needle tube have internal receiving cavities. The first temperature sensor, PCB board, and antenna are all disposed within the receiving cavities and are electrically connected to the PCB board. The antenna is a hard-base antenna, including a hard substrate and an antenna metal layer disposed on the hard substrate, with the rear end of the antenna metal layer extending into the handle. This application uses a hard-base antenna instead of the original FPC antenna. The hard-base antenna uses a hard substrate, which results in less deformation or less deformation under high-temperature environments. However, under high pressure or liquid environments, gas or liquid can easily seep into the connection between the needle tube and the handle of the temperature probe, leading to damage to the temperature probe and hindering its normal use in harsh environments. Summary of the Invention

[0004] To address the problem that gas or liquid can easily seep into the connection between the probe tube and the handle of a temperature probe, making it unusable in harsh environments, this application provides a wireless temperature probe.

[0005] The wireless temperature probe provided in this application adopts the following technical solution. A wireless temperature probe includes: syringe; The first thermistor and the battery are located inside the needle tube, with the first thermistor connected to the battery. Handle, connected to the syringe; A wireless charging coil is located inside the handle and connected to the battery; A connecting clamp is located between the needle tube and the handle. The connecting clamp is welded to the needle tube, and a glass ring is provided between the connecting clamp and the handle. The glass ring is welded to the connecting clamp and the handle respectively to seal the wireless temperature probe.

[0006] By adopting the above technical solution, the needle and handle are connected by a connecting clamp, which facilitates sealing the connection between the needle and handle. Because the needle and handle are made of different materials and vary in size, they are usually difficult to weld and can only be connected using mechanical structures such as threads. However, mechanical connections cannot achieve a high degree of sealing, and leakage is likely to occur under high pressure or liquid immersion. Adding a connecting clamp allows it to be welded to needles and handles of different sizes and materials, improving the seal between them. The glass ring fills the gap between the handle and the connecting clamp, and welding them together integrates the connecting clamp, glass ring, and handle, further enhancing the sealing effect. The first thermistor is connected to the battery, enabling it to receive power for temperature detection. The battery is connected to the wireless charging coil, allowing it to be recharged and ensuring the normal operation of the temperature probe.

[0007] Optionally, it may also include a control mechanism, which includes a circuit board and an antenna. The antenna is connected to the circuit board, which is located inside the needle tube, and the antenna is located inside the handle.

[0008] By adopting the above technical solution, the circuit board can control the working mode of the first thermistor and the battery, and collect the temperature measurement data of the first thermistor. It can also connect to external devices through an antenna, enabling operators to wirelessly control the temperature probe and obtain temperature measurement data, thereby improving the applicability of the temperature probe.

[0009] Optionally, a second thermistor may also be included, which is located inside the handle.

[0010] By adopting the above technical solution, the second thermistor is placed inside the handle away from the first thermistor, enabling the second thermistor to measure the external ambient temperature relative to the measurement environment of the first thermistor, thereby forming a comparison with the measurement of the first thermistor, which is beneficial to the measurement diversity and accuracy of the temperature probe.

[0011] Optionally, it also includes a connection mechanism, which includes a main line and branch lines. The main line is connected to the first thermistor, the battery and the circuit board respectively. The main line is connected to multiple branch lines, each of which is connected to the wireless charging coil, the antenna and the second thermistor.

[0012] By adopting the above technical solution, since the first thermistor, battery and circuit board are all installed in a needle tube with a small inner diameter, they are all connected by the main line, which facilitates the control of the temperature probe. The main line connects to multiple branch lines for connecting the components located in the handle. Since the handle has a large space, it is difficult for a single main line to complete all the connections. Therefore, branch lines are provided to ensure the connection of each component.

[0013] Optionally, the needle tube is connected to a protective sheath that covers the outside of the branch line.

[0014] By adopting the above technical solution, the protective conduit can fix the branch line and ensure that the branch line will not be greatly damaged under impact.

[0015] Optionally, the handle includes a fixture with a wireless charging coil surrounding its outer side and a branch wire passing through its interior to connect an antenna and a second thermistor.

[0016] By adopting the above technical solution, the fixing component is located inside the handle to fix the various parts inside the handle, similar to that of other countries.

[0017] Optionally, the connecting clamp has a retaining ring through which the portion of the sheath protruding from the needle tube passes.

[0018] By adopting the above technical solution to fix the various components inside the handle, it is beneficial to the normal operation of components such as the wireless charging coil and antenna.

[0019] Optionally, the glass ring is a borosilicate glass ring.

[0020] By adopting the above technical solution, high borosilicate glass as a welding material has the advantages of high processing precision, small heat-affected zone, not easy to break, high connection strength, good heat resistance and high chemical stability, which can ensure a tight connection between the syringe and the handle.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By adding a connecting clamp, the connecting clamp can be welded to syringes and handles of different sizes and materials, improving the sealing between the syringe and handle; the glass ring can fill the gap between the handle and the connecting clamp, and by welding the two together, the connecting clamp, glass ring and handle are integrated, improving the sealing effect; 2. The circuit board can control the working mode of the first thermistor and the battery, and collect the temperature measurement data of the first thermistor. It can also connect to external devices through an antenna, enabling operators to wirelessly control the temperature probe and obtain temperature measurement data, thereby improving the applicability of the temperature probe. 3. The second thermistor is located inside the handle away from the first thermistor, so that the second thermistor can measure the external ambient temperature relative to the measurement environment of the first thermistor, thereby forming a comparison with the measurement of the first thermistor, which is beneficial to the measurement diversity and accuracy of the temperature probe.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] A wireless temperature probe, reference Figure 1 and Figure 3 The device includes a needle tube 1, a handle 4, and a connecting clamp 6. The needle tube 1 and handle 4 are of different thicknesses. The connecting clamp 6, a trumpet-shaped structure, connects the needle tube 1 and handle 4, which are of different thicknesses. The narrower end of the connecting clamp 6 is laser-welded to the needle tube 1. One end of the handle 4 has a smaller connecting portion, and the thicker end of the connecting clamp 6 fits over the connecting portion of the handle 4. A glass ring 61 is also provided between the connecting portion of the handle 4 and the connecting clamp 6. The glass ring 61 is made of high borosilicate glass and can be integrally formed with the connecting clamp 6 and handle 4 after high-temperature processing, thereby achieving a sealed fixation between the connecting clamp 6 and handle 4. By sealing the needle tube 1 and handle 4 with the connecting clamp 6, the temperature probe can perform temperature detection in high-pressure or liquid environments.

[0026] Reference Figure 1 and Figure 2 The probe includes a needle tube 1 containing a first thermistor 2 and a battery 3, and a handle 4 containing a wireless charging coil 5 and a second thermistor 8. The temperature probe also includes a control mechanism 7 and a connection mechanism 9. The control mechanism 7 includes a circuit board 71 and an antenna 72, and the connection mechanism 9 includes a main line 91 and branch lines 92. The circuit board 71 and the main line 91 are located inside the needle tube 1, and the first thermistor 2 and the battery 3 are both connected to the main line 91. The circuit board 71 is connected to both sides of the main line 91, used to receive external signals through the antenna 72 and control the working state of the battery 3 and the first thermistor 2, or to collect the detection data of the first thermistor 2 and transmit it to the outside through the antenna 72. The antenna 72 is spirally arranged inside the handle 4, capable of receiving or transmitting external signals. Furthermore, a second thermistor 8 is also located inside the spiral antenna 72, used to detect the ambient temperature outside the handle 4, thus providing a comparison with the detection data of the first thermistor 2 and improving the detection diversity of the temperature probe. The branch line 92 connects to the main line 91, which extends from the needle tube 1 into the handle 4, and connects to the wireless charging coil 5, the second thermistor 8, and the antenna 72 inside the handle 4, thereby completing the connection of the components in the temperature probe.

[0027] Reference Figure 1 and Figure 3 The needle tube 1 is connected to a protective tube 11, which passes through the control mechanism 7 and enters the handle 4. There are three protective tubes 11, which are used to protect and fix three branch lines 92, respectively. The three branch lines 92 are connected to the wireless charging coil 5, the antenna 72, and the second thermistor 8. The connecting clamp 6 is also provided with a fixing ring 62. The protective tube 11 passes through the fixing ring 62, which can fix the protective tube 11 on the outside of the needle tube 1, thereby ensuring the stability of the protective tube 11 on the outside of the needle tube 1. The handle 4 is provided with a fixing member 41. The wireless charging coil 5 is installed between the fixing member 41 and the side wall of the handle 4. Two branch lines 92 pass through the fixing member 41. The antenna 72 and the second thermistor 8 are installed on the side of the fixing member 41 away from the needle tube 1. The two branch lines 92 are connected to the antenna 72 and the second thermistor 8, respectively. The components inside the handle 4 are installed through the fixing member 41, making the internal structure of the temperature measuring probe more stable.

[0028] The implementation principle of this embodiment is as follows: Battery 3 provides power to drive the various power-consuming components of the temperature probe. The first thermistor 2 and the second thermistor 8 can detect the ambient temperature and send the detection data to the circuit board 71 for processing. The data is then transmitted to the outside world through the antenna 72, which can also receive external signals. The circuit board 71 adjusts the operating status of each component. The wireless charging coil 5 provides power to the battery 3, enabling the temperature probe to be used continuously for a long time. The connecting clamp 6 connects the needle tube 1 and the handle 4, forming a sealed structure to effectively prevent gas and liquid penetration, ensuring the stability and safety of the wireless temperature probe.

[0029] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
