Description

Technical Field

[0001] The utility model relates to the technical field of moisture detection, in particular to a moisture measuring instrument. Background Art

[0002] A moisture meter is an instrument that can detect the moisture content in various organic and inorganic solids, liquids, gases and other samples. The main working principle is that the infrared heating unit and the moisture evaporation channel inside the moisture meter quickly dry the sample. During the drying process, the moisture meter continuously measures and instantly displays the moisture content lost by the sample. After the drying process is completed, the final measured moisture content value is locked and displayed. It is easy to use and has fast detection, so it is widely used. However, the applicant found in actual use that when the moisture meter is turned on, some of the residual water vapor will escape, posing a safety hazard of burns.

[0003] In the prior art, the patent document with announcement number 202020189922.2 discloses that "when the upper cover needs to be opened, the pressing plate is pressed, and the pressing plate squeezes the compression elastic part. The pressing plate drives the connecting plate to rotate around the rotating shaft through the connecting assembly. Since the movement direction of the pressing plate is opposite to the movement direction of the connecting plate, when the pressing plate is pressed downward, the connecting plate drives the upper cover to rotate upward to open the upper cover. In the process of opening the upper cover, the operator can open the upper cover without direct contact with the upper cover, thereby avoiding burns to the operator when opening the upper cover." From the technical effect point of view, the above-mentioned prior art can avoid the problem of scalding to a certain extent, but manual operation is still required during the specific operation, and the arm needs to be retracted in time to avoid burns, and there are still defects in the structure.

[0026] Working principle:

[0027] Embodiment 1

[0028] When it is necessary to turn over and open the sealing component 3, the servo motor 74 can be started.

And because the overall operation is an automated operation, it can fundamentally prevent the operator from contacting the residual steam.

[0029] Embodiment 2

[0030] When it is necessary to turn over and open the sealing component 3, the servo motor 74 can be started.

And because the overall operation is an automated operation, it can fundamentally prevent the operator from contacting the residual steam;

[0031] To ensure the accidental turning over of the turned-over sealing component 3 and the arc-shaped rack 5, the electromagnet 8 can be started. The electromagnet 8 magnetically connects to the arc-shaped rack 5, and then ensures the stability of the turned-over sealing component 3 and the arc-shaped rack 5.

[0032] Embodiment 3

[0033] When it is necessary to turn over and open the sealing component 3, the servo motor 74 can be started.
