[0002] Combustion analysis instruments are a class of precision analytical devices used to determine the content of specific elements (especially carbon, hydrogen, nitrogen, sulfur, oxygen, etc.) in substances (mainly solid or liquid samples). Their core principle is: under high temperature and a specific gaseous atmosphere (usually oxygen or an inert carrier gas), the sample is completely combusted (oxidized or pyrolyzed), and then the gaseous products of combustion are separated and accurately measured to calculate the content of the target element in the sample.

[0003] A search revealed Chinese patent CN119555740A, which discloses a rapid combustion device and a multifunctional combustion analyzer. This device uses laser ignition and includes an internal stirring device, enabling rapid testing, fast temperature conduction, and uniform temperature at the measurement points. Furthermore, it incorporates a constant temperature chamber to ensure it is unaffected by external ambient temperature, improving measurement accuracy and precision. However, after use, the sample burns inside the crucible, leaving ash and coke residue that requires cleaning. Since the crucible is located inside the combustion chamber, cleaning is inconvenient. Therefore, a combustion analysis instrument that is easy to clean is proposed to solve this problem. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 This utility model provides a technical solution for a combustion analysis instrument that is easy to clean:

[0026] A combustion analysis instrument that is easy to clean includes a combustion unit 1 and an analysis unit. The combustion unit 1 is used to burn the combustible material to be analyzed, converting specific elements or energy in the sample into measurable gaseous forms. The analysis unit is used to analyze the composition of the gas produced by combustion. The gas produced by sample combustion enters the analysis component, which is existing technology. Its principle is to remove interfering components such as water and impurity gases from the combustion gas, and convert the specific gas into a detectable form. Then, physical separation is achieved using a gas chromatography column, and finally, a thermal conductivity detector and a non-dispersive X-ray diffraction (NDT) detector are used. The combustion unit 1 includes an outer casing 11, an insulation shell 12 fixedly connected inside the outer casing 11, a crucible 13 inside the insulation shell 12 for holding combustible samples, a lifting seat 14 on the top of the outer casing 11 that can be raised and lowered vertically, a support part 15 fixedly connected to the bottom of the lifting seat 14, the crucible 13 being placed on the support part 15, and a connector 16 on the top of the crucible 13, which fixes the crucible 13 to the support part 15 to maintain the stability of the crucible 13 during sample combustion.

[0027] Specifically, by moving the lifting seat 14 upward, the support part 15 and the crucible 13 are moved upward and removed from the insulation shell 12, making it convenient for the user to operate the crucible 13. By setting the connecting piece 16, it is convenient to disassemble the crucible 13 and the support part 15 so that the user can remove the crucible 13 for cleaning, thus making the easy-to-clean combustion analysis instrument easy to clean.

[0028] The support part 15 includes a connecting rod 151 fixedly connected to the bottom of the lifting seat 14. The end of the connecting rod 151 is fixedly connected to a support seat 152. The support seat 152 is ring-shaped. The support seat 152 is fixed to the bottom of the lifting seat 14 by the connecting rod 151, so that it can move synchronously with the lifting seat 14. The ring-shaped support seat 152 facilitates the placement of the crucible 13.

[0029] The top of the crucible 13 has an annular wall 131, the bottom of which fits against the top of the support 152 for cooperating with the support 152 to support the crucible 13. The outer diameter of the crucible 13 matches the inner diameter of the support 152. The surface of the annular wall 131 is fixedly connected with a lug 134 to reduce the shaking of the crucible 13 and improve its stability.

[0030] The top of the annular wall 131 is provided with a through hole 132, the connector 16 is a threaded rod, the threaded rod is located inside the through hole 132, the top of the support 152 is provided with a threaded hole, and the threaded rod is threadedly connected to the inner wall of the threaded hole.

[0031] The top of the connector 16 is fixedly connected to a strip-shaped knob seat 161. The top of the annular wall 131 has a through-hole 133 that matches the knob seat 161. By rotating the knob seat 161, the threaded rod is rotated, so that the knob seat 161 presses against the top of the annular wall 131, connecting the crucible 13 to the support seat 152. When disassembly is required, the knob seat 161 is rotated in the opposite direction so that the knob seat 161 corresponds to the through-hole 133, and the crucible 13 can be removed using the lifting lug 134.

[0032] The top of the outer casing 11 is fixedly connected to the cover 111, the top of the insulation shell 12 is fixedly connected to the bottom of the cover 111, and the top of the cover 111 has an opening 112 corresponding to the opening of the insulation shell 12.

[0033] A boss 141 is formed on the top of the lifting seat 14, and a rubber ring 142 is fixedly connected to the bottom of the boss 141. An electric slide 2 is fixedly connected to the back of the outer box 11. A transmission rod 3 is fixedly connected to the output end of the electric slide 2. One end of the transmission rod 3 is fixedly connected to the surface of the boss 141. The transmission rod 3 is driven to move upward through the output end of the electric slide 2, which in turn drives the boss and the lifting seat 14 to move upward, and in turn drives the support part 15 and the crucible 13 to move upward.

[0034] The bottom of the lifting seat 14 is fixedly connected to an igniter 4 corresponding to the crucible 13, and the combustible sample is ignited by the igniter 4.

[0035] Working principle: When this easy-to-clean combustion analysis instrument needs cleaning, the user first activates the electric push rod. The output end of the electric slide 2 drives the transmission rod 3 to move upward. The transmission rod 3 drives the protrusion and the lifting seat 14 to move upward. The lifting seat 14 drives the connecting rod 151 to move. The connecting rod 151 drives the support part 15 and the crucible 13 to move upward, so that the crucible 13 is removed from the heat preservation shell 12, making it convenient for the user to operate the crucible 13. Then, the knob seat 161 is rotated. The knob seat 161 drives the threaded rod to rotate in the loosening direction until the knob seat 161 corresponds to the through hole 133. The crucible 13 can then be removed using the lifting lug 134. The crucible 13 can then be cleaned, thus making this easy-to-clean combustion analysis instrument easy to clean.
