[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] Example 1: This utility model provides a segmented controllable encapsulation heating system, including a probe assembly 1, which includes a probe rod 101 and an atomic probe 102. The probe rod 101 is fixedly installed on the operating arm of the detection equipment, and the atomic probe 102 is fixedly installed at the bottom of the probe rod 101. It also includes a heating assembly, which consists of a switching mechanism 2 and an encapsulation mechanism 3.

[0026] The switching mechanism 2 includes a drive motor 201, a positioning rod 202, and a retainer 203. The drive motor 201 is fixedly installed on the top of the probe rod 101, and the positioning rod 202 is rotatably connected to the top of the probe rod 101. The shaft of the drive motor 201 is connected to one end of the positioning rod 202, and the retainer 203 is inserted into the top of the probe rod 101. The covering mechanism 3 includes a covering heating cover and a linkage rod 302. The covering heating cover is composed of three semi-conical heating sleeves 301 fixedly connected end to end, and the top heating sleeve 301 is rotatably connected to the side of the probe rod 101. The linkage rod 302 is inserted into the shaft of the top heating sleeve 301, and one end of the linkage rod 302 is fixedly installed on the side of the retainer 203.

[0027] In this embodiment, the coating mechanism 3 is provided in two sets, and the two sets of coating mechanisms 3 are symmetrically arranged on both sides of the retainer 203. The heating sleeves 301 are arranged along the axial direction of the atomic probe 102, and the heating temperature of each heating sleeve 301 can be independently controlled. In use, the coating mechanism 3 has two usage states: heating state and detection state. When the atomic probe 102 needs to be heated, the coating mechanism 3 is in the heating state. At this time, the heating cover is wrapped around the atomic probe 102, so that the atomic probe 102 is heated by the segmented heating sleeves 301. Each segment of the heating sleeve 301 can be independently powered and its temperature can be adjusted to achieve precise temperature control and heating to meet different detection needs. When the atomic probe 102 is used for detection, the coating mechanism 3 is in the detection state. At this time, the heating cover can be flipped up to separate from and move away from the atomic probe 102, so that the atomic probe 102 can be used for detection independently and the detection accuracy is improved.

[0028] In this embodiment, the positioning rod 202 has threads on its outer surface and is screwed into the cage 203 via these threads. During use, the heating and detection states of the covering mechanism 3 can be switched via the switching mechanism 2, making operation convenient and flexible. When the drive motor 201 rotates, it drives the positioning rod 202 to rotate. The rotation of the positioning rod 202 drives the cage 203 to move via its threads. The movement of the cage 203 drives the linkage rod 302 to move synchronously. The linkage rod 302 has a spiral-shaped linkage groove 30 on its outer surface. 21, and the outer side of the rotating shaft of the top heating sleeve 301 is provided with a linkage protrusion 3011. The linkage protrusion 3011 is inserted into the inside of the linkage groove 3021. When the linkage rod 302 moves, the linkage groove 3021 can drive the heating cover to rotate through the linkage protrusion 3011. When the covering mechanism 3 is in the heating state, the switching mechanism 2 flips the heating cover down to the outside of the atomic probe 102 for heating. When the covering mechanism 3 is in the detection state, the switching mechanism 2 flips the heating cover up so that it is separated from the atomic probe 102 and moves away from it. The switching is quick and convenient.

[0029] In this embodiment, the heating jacket 301 is made of a high thermal conductivity, low resistivity alloy material, such as a platinum-rhodium alloy, to improve heating efficiency and temperature uniformity. Furthermore, each heating jacket 301 has a miniature temperature sensor embedded inside for convenient temperature control operation.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this invention, the covering mechanism 3 has two operating states: a heating state and a detection state. When the atomic probe 102 needs to be heated, the covering mechanism 3 is in the heating state, where the heating cover is wrapped around the atomic probe 102. The segmented heating sleeves 301 heat the atomic probe 102, and each segment can be independently powered and its temperature adjusted, achieving precise temperature control to meet different detection needs. When the atomic probe 102 is being used for detection, the covering mechanism 3 is in the detection state. In this state, the heating cover can be flipped up to separate from and move away from the atomic probe 102, facilitating independent detection of the atomic probe 102. The heating and detection states of the covering mechanism 3 are described. The switching mechanism 2 can be used to switch between different states, making operation convenient and flexible. When the drive motor 201 rotates, it can drive the positioning rod 202 to rotate. When the positioning rod 202 rotates, it can drive the retainer 203 to move through the rod thread. When the retainer 203 moves, it can drive the linkage rod 302 to move synchronously. Thus, when the linkage rod 302 moves, the linkage groove 3021 can drive the heating cover to rotate through the linkage protrusion 3011. When the covering mechanism 3 is in the heating state, the switching mechanism 2 flips the heating cover down to the outside of the atomic probe 102 for heating. When the covering mechanism 3 is in the detection state, the switching mechanism 2 flips the heating cover up so that it is separated from the atomic probe 102 and moved away from it. The switching is quick and convenient.
