[0024] Example
[0025] See also Figure 1-Figure 6 A constant temperature heating mechanism for a trace moisture meter comprises an instrument body 1, a detection tank 2 and a heating mechanism, wherein the heating mechanism comprises two heating barrels 3, wherein one heating barrel 3 is fixedly connected to the top of the instrument body 1, and the other is slidably arranged at the top of the instrument body 1 through a limiting structure, a card and structure are arranged between the two heating barrels 3, an infusion tube 4 is arranged at the top of the heating barrel 3, and a sealing cap 5 is screwed on the top of the infusion tube 4, a plurality of heating rods 6 are installed inside the heating barrel 3, a temperature sensor 7 is embedded on the outer wall of the heating barrel 3, and the heating rod 6 and the temperature sensor 7 are electrically connected to the instrument body 1.
[0026] It is convenient to adjust the liquid for heating to the inside of the heating barrel 3 through the infusion tube 4, and then the heating rod 6 can be energized to heat the liquid inside the heating barrel 3, so that the heating barrel 3 heats the detection tank 2, and the detection tank 2 is heated evenly, which is beneficial to improve the accuracy of the detection result and is more conducive to practical use. Since the heating rod 6 and the temperature sensor 7 are electrically connected to the instrument body 1, it is convenient to control the heating temperature through the instrument body 1. The setting method, installation method and electrical connection method thereof are only required to be debugged according to the requirements of the instruction manual for technicians in this field, and will not be described in detail here.
[0027] See also Figure 1 and Figure 5The limiting structure includes a fixed groove 8, which is fixedly connected to the top of the instrument body 1. A slider 9 is slidably arranged inside the fixed groove 8. The slider 9 is fixedly connected to the slidable heating barrel 3. A fixing rod 10 is fixedly connected to the top of the slider 9. A fixing structure is arranged on the side wall of the fixed groove 8.
[0028] By setting the fixing groove 8 and the slider 9, a limiting effect can be played on the heating barrel 3 fixedly connected to the slider 9, so that the heating barrel 3 can only slide, which is beneficial to improving the stability of the heating barrel 3. At the same time, by pushing the fixing rod 10, the heating barrel 3 can slide, which makes it convenient for the heating barrel 3 and another heating barrel 3 to support the detection tank 2, so that it can play a normal heating effect.
[0029] See also Figure 5 The fixed structure includes a shell 11, which is fixedly connected to the outer wall of the fixing groove 8. A slider 12 is slidably arranged inside the shell 11. A spring 13 is arranged between the slider 12 and the inner wall of the shell 11. A limit rod 14 is fixedly connected to the side wall of the slider 12. The limit rod 14 is plugged into the slider 1 9. A pull rod 15 is fixedly connected to the side wall of the other end of the slider 12.
[0030] By pulling the pull rod 15, the limit rod 14 moves under the connection action of the slider 2 12, so as to facilitate the normal sliding of the heating barrel 3. At the same time, when the heating barrel 3 is fitted with the outer wall of the detection tank 2, by loosening the pull rod 15, the slider 2 12 drives the limit rod 14 to be inserted into the slider 1 9 under the action of the spring 13, so that the position of the slider 1 9 can be fixed, and the position of the heating barrel 3 is fixed, so that the two heating barrels 3 can support the detection tank 2, which is beneficial to improve the heating effect.

[0033] See also Figure 1 and Figure 4 A heat-insulating layer 19 is provided on the outer wall of the heating barrel 3 .
[0034] The provision of the heat-insulating layer 19 can reduce the heat loss of the heating barrel 3, making the device more energy-efficient.
[0035] In summary, the working principle and working process of the constant temperature heating mechanism for the trace moisture meter are as follows: when in use, the constant temperature heating mechanism for the trace moisture meter is first placed at the desired location, and then the detection tank 2 is placed on the top of the instrument body 1, the pull rod 15 is pulled, and then the fixing rod 10 is pushed, so that the two heating barrels 3 support the detection tank 2, and then the pull rod 15 can be loosened, so that the limit rod 14 is inserted into the interior of the slider 9 to fix the bottom end of the heating barrel 3, and then the clamping block 18 is clamped to the interior of the fixing block 16 to fix the top end of the heating barrel 3, and the sealing cap 5 is opened, and the liquid for heating is added to the interior of the heating barrel 3 through the infusion tube 4, and then the sealing cap 5 is covered, and then the heating temperature is set through the instrument body 1, and the instrument body 1 can be started, so that the heating rod 6 heats the liquid inside the heating barrel 3, and the constant temperature heating mechanism of the trace moisture meter can achieve the effect of uniform heating of the detection tank 2, which can improve the accuracy of the detection result, has high practicality, and is simple in actual operation, which is conducive to popularization and application.
