The analyzer body has an open slot on its left side, a tilted display screen at the upper rear end of the slot, and flush control keys at the bottom of the slot. A weighing pan is mounted on the top of the analyzer body, a base plate is located at the bottom right end of the analyzer body, and a top plate is mounted on the upper right side of the analyzer body, with the base plate and top plate aligned vertically. This invention integrates the weighing pan and concentration detector into a single structure, allowing the analyzer to perform multiple data analyses on materials without requiring multiple instruments, thus improving work efficiency and data analysis accuracy.

The fan blades 25 are fixed to the fixing plate 21. The plates 21 are rotatably connected. The nozzles 28 are fixed to the inner wall of the humidification tank 26 through the through groove 27.

[0020] In this embodiment, the accuracy and stability of the constant temperature and humidity environment are improved.

Compared with traditional equipment, it has significant advantages in terms of environmental uniformity, ease of operation and long-term operational stability.
[0021] Example 2: As Figure 1 , Figure 2 , Figure 4 As shown, a limiting plate 44 is provided at the top of the base 1, a limiting block 46 is provided inside the limiting plate 44, a sliding rod 47 is fixedly installed in the middle of the limiting block 46, a cleaning plate 48 is fixedly installed at the bottom of the sliding rod 47, and a pinching plate 49 is fixedly installed at the top of the sliding rod 47.

The limiting block 46 is slidably connected to the limiting plate 44 through the limiting groove 45, the sliding rod 47 is slidably connected to the limiting plate 44, and the cleaning plate 48 is slidably connected to the display screen 3.
[0022] In this embodiment, the practicality and maintenance efficiency of the equipment are effectively improved by adding a symmetrical limiting plate 44 and a linkage cleaning mechanism. The limiting plate 44 with a double-end symmetrical layout, together with the sliding limiting block 46, forms a stable guiding constraint system to ensure operational accuracy. The innovatively designed sliding rod 47 synchronously drives the cleaning plate 48, which can achieve convenient dust removal of the display screen 3 area without disassembling the main structure, avoiding dust accumulation from affecting observation. The integrated design of the pinch plate 49 and the sliding rod 47 simplifies the operation process and makes the cleaning action more labor-saving and efficient. Each sliding pair adopts a precision fit design, which not only ensures smooth movement but also reduces the risk of wear, improves the maintainability and long-term operational reliability of the equipment, and optimizes the human-machine interaction experience.
[0023] The working principle of this embodiment is as follows: First, place the base 1 in the desired position, ensuring the support pad 2 firmly supports it. Then, pinch the handle 13 and pull upwards, causing the handle 13 to slide the cover plate 11 upwards. The cover plate 11 slides upwards in the middle of the outer shell 6, and the locking plate 10 slides upwards inside the outer shell 6 via the locking groove 9. The sample can then be placed on the top of the platform 5. After closing the cover plate 11, the display screen 3 is activated via the switch 4, and use can begin. During use, the heating tank 16 and humidifying tank 26, separated by the partition 15, can humidify the interior of the outer shell 6. For heating or humidification, when heating is needed, the heating grid 18 of the heating tank 16 inside the cabinet 14 can be activated, and then the motor 23 on the right side of the fixing plate 21 can be activated, causing the motor 23 to drive the rotating block 24 to rotate through the rotating groove 22. At this time, the fan blade 25 rotates on the left side of the fixing plate 21 through the rotating block 24, thereby blowing air through the fixing rod 19 and the fixing ring 20 towards the outer shell 6, and blowing the hot air emitted by the heating grid 18 into the interior of the outer shell 6 through the groove 17. At this time, the air can dissipate heat through the heat dissipation vent 37 on the cover 36. When humidification is needed, the water pump of the humidification tank 26 inside the cabinet 14 can be activated. 32. The water pump 32 pours a small amount of water from inside the water tank 33 into the conduit 29 through the hose 31, and then completely pours it into the nozzle 28 through the connecting pipe 30. The nozzle 28 then sprays water into the inside of the outer casing 6 through the through groove 27. After prolonged use, when water needs to be added or the motor 23 needs maintenance, first squeeze the handle 43 to turn it, causing the threaded rod 42 to rotate outward through the threaded groove 41 inside the housing 14. Once the threaded rod 42 has completely rotated out of the housing 14 through the threaded groove 41, it can be removed from the fixing block 39 through the fixing groove 40. Then, squeeze the side plate 38 and pull it backward, causing the cover 36 to pass through the hinge 3. 5. The machine rotates backward inside the housing 14 so that the staff can add water to the water tank 33 through the water inlet 34 and maintain the motor 23. During use, the staff can observe the sample through the transparent plate 8 inside the top plate 7 and the transparent glass 12 inside the cover plate 11. When it is necessary to clean the display screen 3, the sliding rod 47 slides in the middle of the limiting plate 44 by pushing and pulling the pinch plate 49. At this time, the limiting block 46 slides inside the limiting plate 44 through the limiting groove 45, so that the sliding rod 47 drives the cleaning plate 48 to move together. At this time, the cleaning plate 48 can clean the surface of the display screen 3.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
