[0034] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] It should be noted that the "base width direction" in this application text is an appendix. Figure 1 The x-axis direction is indicated by the "base length direction". Figure 1 The direction of the y-axis. The terminology used in this specification is for the purpose of describing specific embodiments only and is not intended to be limiting of the invention.

[0038] During the measurement of product moisture content, it is inevitable that some test material will fall into the heating tray. This fallen material forms dirt in the heating tray, which can affect the product test results and the customer's user experience. Therefore, it is necessary to clean this dirt. However, because the heating tray and base of existing moisture meters are designed as a single unit, the entire machine needs to be tilted for cleaning, which makes the cleaning operation difficult and may damage the moisture meter during the process. Therefore, the applicant proposes a base structure for a moisture meter to solve the above problems.

[0039] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0040] Reference Figure 1 , Figure 2 As shown, the base structure of the moisture measuring instrument in this embodiment includes a base 1, an air duct cover 2, and a heating tray 3; the base 1 is recessed with a receiving groove 11, the air duct cover 2 is detachably installed in the receiving groove 11, the heating tray 3 is detachably installed on the air duct cover 2 and disposed on the base 1, and the heating tray 3 is partially received in the receiving groove 11.

[0041] By incorporating a portable and detachable heating tray 3, when a user spills a test sample onto the heating tray 3, the contaminated tray 3 can be directly removed and cleaned before being reinstalled. Compared to the base structure of existing moisture meters, the base structure of the moisture meter in this embodiment does not require operation of the entire unit; only the heating tray 3 needs to be removed for quick and convenient cleaning, reducing the disassembly and assembly work required for cleaning the entire unit.

[0042] Reference Figure 2 As shown, the heating tray 3 in this embodiment includes a plate 31 and a groove 32 recessed in the plate 31. The plate 31 abuts against the base 1, and the groove 32 is received in the receiving groove 11. For example, the groove 32 in this application is located in the middle of the plate 31, that is, the groove 32 is connected to the plate 31 on all four sides. It should be noted that the moisture meter in this embodiment also includes a top cover, which is rotatably mounted on the base 1. When the top cover is closed on the base 1, the top cover and the heating tray 3 form a heating chamber, which is located above the groove 32. Therefore, during the user's moisture content test, the test material may fall into the groove 32, thereby contaminating the heating tray 3.

[0043] Of course, this application is not limited to this. In other embodiments, the groove 32 may be connected to the plate 31 on both sides along the width direction of the base 1, while the groove 32 may not be provided with the plate 31 on both sides along the length direction of the base 1; or, the groove 32 may be connected to the plate 31 on both sides along the length direction of the base 1, while the groove 32 may not be provided with the plate 31 on both sides along the width direction of the base 1.

[0044] The groove 32 of the heating tray 3 adopts a box-shaped structure, which ensures the strength of the heating tray 3 and extends its service life.

[0045] To facilitate the placement of the heating tray 3 on the base 1, refer to... Figure 1 , Figure 2 As shown, in this embodiment, the base 1 is also provided with an assembly slot 12 located above the receiving slot 11 and connected to the receiving slot 11, and the plate 31 is installed in the assembly slot 12.

[0046] Specifically, refer to Figure 2As shown, in this embodiment, the plate 31 includes a main body 311 and two bent portions 312 disposed opposite to each other on both sides of the main body 311 along the width direction of the base 1. The mounting groove 12 includes a first groove 121 that mates with the main body 311 and two second grooves 122 that mate with the two bent portions 312 respectively. When the heating tray 3 is placed on the base 1, the two sides of the plate 31 along the length direction of the base 1 in this embodiment abut against the groove walls of the first groove 121, and the bottom surface of the bent portion 312 abuts against the groove walls of the second groove 122. Through the matching design of the plate 31 and the mounting groove 12, the heating tray 3 can be accurately positioned and can be quickly and stably installed on the air duct cover 2.

[0047] Optional, refer to Figure 1 As shown, in this embodiment, the main body 311 is flush with the upper surface of the base 1, and the bent portion 312 has a groove. Compared with the scheme where the main body 311 and the bent portion 312 protrude or are recessed into the base 1, the design in this embodiment makes the outer surface of the entire moisture meter base structure smooth, reducing the cleaning dead angle range of the instrument surface.

[0048] Preferably, refer to Figure 2 As shown, the bent portion 312 in this embodiment has a recessed portion 300. The user can insert their hand or an auxiliary structure into the recessed portion 300 to assemble or disassemble the heating tray 3.

[0049] Furthermore, to prevent burns to the hands from excessively high temperatures on the heating tray 3, refer to... Figures 2-5 As shown, in this embodiment, the heating tray 3 is larger in width direction than the air duct cover 2. An air outlet 4 is formed between the bent portion 312 and the base 1. An air inlet 13 is provided on the base 1, and a gas flow channel is formed between the air inlet 13 and the air outlet 4. A ventilation opening 5 is formed between the air duct cover 2 and the base 1, located in the gas flow channel. The air outlet 4 can be formed by directly inserting the recessed portion 300 through the bent portion 312 to form a groove. The bent portion 312 abuts against the base 1 to form the air outlet 4.

[0050] It should be noted that the base 1 of the moisture meter's base structure is equipped with an air outlet structure. This air outlet structure allows external gas to be introduced into the base 1 through the air inlet 13, flow through the gas flow channel, and finally exit the base 1 and heating tray 3 through the air outlet 4. Based on this design, some of the heat from the heating tray 3 can be carried away. Of course, this air outlet structure can also be located externally, as long as it can introduce external gas into the base 1 and drive the gas to flow from the air inlet 13 to the air outlet 4 in the gas flow channel.

[0051] During the measurement of product moisture content, debris may occasionally fall into the air duct. To facilitate quick and easy cleaning of the air duct, the air duct cover 2 in this embodiment is detachably installed in the receiving groove 11. The air duct cover 2 and the base 1 together form the air duct. By removing the air duct cover 2, the inside of the air duct can be cleaned conveniently and quickly.

[0052] Among them, reference Figure 2 As shown, the duct cover 2 in this embodiment includes a base plate 21, two end plates 22 disposed opposite to each other on both sides of the base plate 21 along the width direction of the base 1, and a connecting plate 23 that connects the two end plates 22 and the base plate 21 respectively. The connecting plate 23 indirectly abuts against the groove 32.

[0053] Specifically, refer to Figure 2 , Figure 3 As shown, in this embodiment, multiple guide structures 231 are spaced apart along the length of the base 1 on the connecting plate 23. The guide structures 231 directly abut against the groove 32, meaning the connecting plate 23 indirectly abuts against the groove 32 through the guide structures 231. For example, two guide structures 231 are provided. It should be noted that when the heating tray 3 does not match the duct cover 2 and cannot be accommodated in the receiving groove 11, the guide structure 231 can be ground to reduce its size, thus facilitating adjustment so that the groove 32 of the heating tray 3 abuts against the guide structure 231, ultimately reliably and stably installing the heating tray 3 onto the duct cover 2. Compared to a solution without guide structures 231, the design in this embodiment reduces the need for further processing of the duct cover 2, avoids grinding the entire connecting plate 23 to install the heating tray 3, and improves the speed of installing the heating tray 3.

[0054] Preferably, in this embodiment, the width of the guide structure 231 gradually decreases from bottom to top. This design facilitates the smooth installation of the guide structure 231 into the air duct cover 2.

[0055] Of course, in other embodiments, the guide structure 231 can also be configured with three, four, or more than or equal to three. Compared to the configuration of guide structures 231 with more than or equal to three, configuring guide structures 231 with two can not only achieve the effect of reliably and stably installing the heating tray 3 on the air duct cover plate 2, but also reduce the amount of grinding work.

[0056] To reduce the possibility of gas flowing into the air duct cover 2 and the heating tray 3, refer to Figure 4 As shown, in this embodiment, the upper surface of the end plate 22 abuts against the lower surface of the plate 31.

[0057] Of course, this application is not limited to this. In other embodiments, the connecting plate 23 and the groove 32 directly abut against each other. In order to facilitate the smooth installation of the guide structure 231 in the air duct cover plate 2, the distance between the two connecting plates 23 gradually increases from bottom to top.

[0058] As can be seen from the above technical solutions, this utility model has the following beneficial effects:

[0059] This utility model provides a base structure for a moisture meter. By setting a detachable heating tray and air duct cover, the contaminated heating tray and the inside of the receiving tank can be cleaned directly, effectively, quickly and conveniently, making it convenient for users. This reduces the workload of cleaning the whole machine while improving the overall reliability of the machine.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0061] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
