[0002] A moisture meter, also known as a moisture analyzer, quickly heats the sample to be tested through an internal heating unit, causing the moisture in the sample to be tested to completely evaporate in a short period of time. The moisture content of the sample can be determined by testing the mass of the sample before and after evaporation.

[0003] Existing moisture meter heating units typically use components that generate heat quickly, such as resistance heaters and halogen lamp heaters. However, resistance heaters have a large heat capacity, making precise temperature control difficult and potentially damaging the sample. Halogen lamp heaters, on the other hand, offer controllable temperature and rapid heating, but they generate excessive visible light, resulting in significant power losses and excessive brightness that can damage the user's eyes.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0009] In one or more embodiments of the present invention, the first straight line segment and the second straight line segment are arranged in parallel.

[0010] In one or more embodiments of the present invention, the carbon fiber heater includes a straight line segment, and a plurality of carbon fiber heaters are provided.

[0011] In one or more embodiments of the present invention, the reflector includes an integrally connected top plate and an annular side plate perpendicular to the top plate.

[0012] In one or more embodiments of the present invention, the cross-section of the annular side plate is rectangular.

[0013] The present invention also provides a moisture meter comprising a base, a weighing unit, and the aforementioned carbon fiber heating unit. The weighing unit is mounted on the top of the base, and the cover of the carbon fiber heating unit is rotatably mounted on the top of the base.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "top", "bottom", "up", "down", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0026] Reference Figures 1 to 5 As shown, a carbon fiber heating unit for a moisture meter in one embodiment of the present invention comprises a cover 1, a heat shield 2, a reflector 3, and a carbon fiber heater 4. The cover 1 defines a receiving cavity with a first opening at one end. The heat shield 2 is mounted within the receiving cavity and has a second opening at one end. The reflector 3 is mounted within the heat shield 2 and has a third opening at one end. The first, second, and third openings are oriented in the same direction. The carbon fiber heater 4 is mounted within the reflector 3.

[0027] In the above embodiment, a carbon fiber heater 4 is selected as the heating source of the moisture meter to replace the traditional resistance wire heating source and halogen heating source. Since the carbon fiber heater 4 has the characteristics of fast response, uniform heating, high temperature stability and adjustable power, it can improve the detection efficiency and accuracy of the moisture meter for the sample to be tested.

[0028] Secondly, the luminous flux of the carbon fiber heater 4 during heating is much lower than that of a metal heater, which can prevent the light generated by the carbon fiber heater 4 from affecting the user's eyes. In addition, the carbon fiber heater 4 has high electrothermal conversion efficiency and strong high temperature resistance, which can significantly improve the electrothermal conversion efficiency and service life of the moisture meter, making it more energy-efficient and environmentally friendly.

[0029] In one embodiment, the carbon fiber heater 4 can be configured as a tubular member, and its shape can be configured as any shape.

[0030] As an example, the carbon fiber heater 4 may be composed of one or more straight line segments, and the number of straight line segments may be set according to actual needs.

[0031] As another example, the carbon fiber heater 4 may be composed of one or more curved segments, and the number of curved segments may be set according to actual needs.

[0032] As another example, the carbon fiber heater 4 can be formed by a combination of straight segments and curved segments. The straight segments and curved segments can be set to one or more, and the number of straight segments and curved segments can be set according to actual needs.

[0033] Preferably, refer to Figure 5 As shown, the carbon fiber heater 4 includes a first straight segment 41 , a second straight segment 42 and an arc segment 43 that are integrally connected. The first straight segment 41 and the second straight segment 42 are respectively arranged at two ends of the arc segment 43 .

[0034] In order to further improve the heating range of the carbon fiber heater 4 and ensure that the sample to be tested in the moisture meter is heated evenly, the arc segment 43 should be set to a circular arc as much as possible, that is, the arc of the arc segment 43 should be as close to 360° as possible, so that the first straight line segment 41 and the second straight line segment 42 are as close as possible.

[0035] In one embodiment, to facilitate fixing of the carbon fiber heater 4 , the first straight segment 41 and the second straight segment 42 are arranged in parallel, so that the carbon fiber heater 4 forms a relatively regular shape, thereby facilitating installation and fixing of the carbon fiber heater 4 .

[0036] In one embodiment, in order to ensure that the carbon fiber heater 4 can uniformly heat the sample to be tested inside the moisture meter, the carbon fiber heater 4 can be composed of a relatively short straight segment, the length of which is significantly smaller than the size of the heat insulation cover 2. In this case, a plurality of carbon fiber heaters 4 can be provided and these carbon fiber heaters 4 can be evenly arranged inside the heat insulation cover 2 to ensure that the sample to be tested inside the moisture meter is heated evenly.

[0037] Reference Figure 4 As shown, the reflector 3 can be composed of a top plate 31 and an annular side plate 32, wherein the top plate 31 is integrally connected to the annular side plate 32, and the annular side plate 32 is arranged perpendicular to the top plate 31, which can achieve a better reflection effect, and the heat radiation of the carbon fiber heater 4 is more concentrated, so that the sample to be tested inside the moisture meter is heated more evenly.

[0038] Preferably, the annular side plate 32 may be composed of four integrally connected plate bodies, and the four plate bodies are arranged to form a rectangular ring structure, that is, the cross-section of the annular side plate 32 is rectangular.

[0039] In one embodiment, in order to improve the heat insulation effect of the heat insulation cover 2 and the light reflection effect of the reflective cover 3, the heat insulation cover 2 and the reflective cover 3 can be made of mirror stainless steel.

[0040] Reference Figure 1 and Figure 2 As shown, another embodiment of the present invention further provides a moisture meter, comprising a base 5, a weighing unit 6, and the above-mentioned moisture meter carbon fiber heating unit. The weighing unit 6 is mounted on the top of the base 5, and is used to carry the sample to be tested and detect the mass of the sample to be tested. The cover 1 of the moisture meter carbon fiber heating unit is rotatably mounted on the top of the base 5, and can be connected to the base 5 by a hinge structure or a pin structure. The first opening of the cover 1, the second opening of the heat insulation cover 2, and the third opening of the reflective cover 3 face the weighing unit 6, so that the carbon fiber heater 4 is located above the weighing unit 6, thereby heating the sample to be tested placed on the weighing unit 6.

[0041] In one embodiment, a groove 51 is provided at the top of the base 5, and the weighing unit 6 is installed in the groove 51. When the cover is closed, the reflector 3 at least partially extends into the groove 51 and surrounds the weighing unit 6 to form a relatively closed heating space.

[0042] Furthermore, the weighing unit 6 includes a tray 61 arranged near the top of the groove 51, and the tray 61 is used to carry the sample to be tested. When the cover is closed, the tray 61 is located in the reflective cover 3 and below the carbon fiber heater 4, and other components and parts are avoided as much as possible between the tray 61 and the carbon fiber heater 4 to reduce heat loss in the reflective cover 3.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
