[0048] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings.

[0049] When users use existing moisture meters to measure the moisture content of products, they sometimes use the handle and sometimes do not use the handle, which makes it impossible to form standardized measurement operation specifications, which easily leads to inconsistent measurement states and ultimately affects the accuracy of the test results. In addition, since the handle is not provided with a structure that matches the heating tray, it is easy for the handle to deform, be placed in the wrong position, or interfere with the heating tray when using it, affecting user use. Therefore, the applicant proposed a handle and a moisture meter to solve the above problems.

[0050] Embodiment 1:

[0051] Reference Figure 1 to Figure 3As shown, the handle in this embodiment is applied to a moisture meter, which includes a heating tray 2, on which a groove 21 is recessed, and the handle is accommodated in the groove 21; the handle includes a ring plate 31 and a limiting structure 32 arranged on the outer wall of the ring plate 31 at intervals along the circumferential direction, and the outer wall of the limiting structure 32 abuts against the inner wall of the groove 21. By providing the limiting structure 32 matched with the groove 21 of the heating tray 2, the handle can be accurately and stably placed at a specific position of the heating tray 2, avoiding the problems of deformation of the handle, improper placement, or interference with the heating tray 2.

[0052] Reference Figure 3 As shown, the handle in this embodiment also includes a plurality of placement plates 33 arranged on the inner wall of the ring plate 31 at intervals along the circumferential direction and a handle body 34 connected to the outer wall of the ring plate 31. The handle body 34 can be directly or indirectly connected to the outer wall of the ring plate 31. The placement plate 33 is used to place the material tray, and the handle body 34 can be held by a person. Through the design of the handle, it is more convenient to shake the material evenly so that the material is spread flat in the material tray.

[0053] Specifically, refer to Figure 4 As shown, the placement plate 33 in this embodiment includes a placement portion 331, a first abutting portion 332 connected to the inner wall, a second abutting portion 333 connected to the placement portion 331, and a connecting portion 334 connecting the first abutting portion 332 and the second abutting portion 333. The material tray is placed on the placement portion 331, and the outer side wall of the material tray can abut against the second abutting portion 333, thereby preventing the material tray from being displaced in the handle. Further, the connecting portion 334 in this embodiment connects the upper end of the first abutting portion 332 with the upper end of the second abutting portion 333 to prevent the material from falling into the placement plate 33.

[0054] Preferably, in the process of placing the handle in the groove 21 of the heating tray 2, in order to prevent the placement plate 33 from abutting against the heating tray 2, refer to Figure 4 As shown, the lower surface of the placement plate 33 of this embodiment is higher than the lower surface of the ring plate 31.

[0055] As the outer diameter of the material tray increases gradually from bottom to top, refer to Figure 4 As shown, the second abutment portion 333 in this embodiment gradually approaches the first abutment portion 332 from bottom to top. According to this design, the outer wall of the material tray can fit with the second abutment portion 333, so that the material tray can be placed on the placement plate 33 quickly and stably.

[0056] Optionally, when the handle body 34 is indirectly connected to the outer wall of the ring plate 31 , the handle body 34 in this embodiment is connected to the outer wall of the ring plate 31 through one of the limiting structures 32 .

[0057] For example, refer to Figure 1 Combined with Figure 3 As shown, since the tank body 21 of the heating tray 2 in this embodiment is a box-shaped design, the tank body 21 has four side walls. Therefore, the outer wall of the ring plate 31 in this embodiment is provided with four limiting structures 32 at intervals along the circumferential direction, and each limiting structure 32 abuts against the corresponding side wall of the tank body 21. It should be noted that, see Figure 5 As shown, the moisture meter includes a base 1 and an upper cover 4, and the heating tray 2 is mounted on the base 1. The upper cover 4 is rotatably mounted on the base 1 through a rotating shaft, and the handle body 34 is connected to a limiting structure 32 arranged away from the rotating shaft. Of course, the number of limiting structures 32 in the present application is not limited to four. If the tank body 21 of the heating tray 2 is cylindrical or polygonal, the limiting structures 32 only need to be greater than or equal to 3, so that the handle can be stably and reliably placed in the tank body 21.

[0058] Reference Figure 1 Combined with Figure 4 As shown, the handle body 34 in this embodiment includes a hand-held portion 341 extending in a direction away from the rotation axis and a bent portion 342 connecting the hand-held portion 341 and the limiting structure 32. The hand-held portion 341 can extend to the outside of the upper cover 4 to prevent the handle from being affected by the heating chamber 6 (see Figure 7 ) due to the heating structure inside, which causes the temperature to be too high and has the effect of preventing burns.

[0059] Reference Figure 1 , Figure 2 As shown, during the process of measuring the moisture content of the product, the upper cover 4 needs to be closed, and a heating chamber 6 is formed between the upper cover 4 and the heating tray 2, and then the material placed in the material tray is heated, that is, the heating chamber 6 is heated. Due to the expansion and contraction of the gas after heating, part of the hot gas will flow upward out of the heating chamber 6. In order to balance the air pressure, the external gas will be replenished into the heating chamber 6 from the gap 9 between the upper cover 4 and the heating tray 2. During the gas replenishment process, in order to prevent the gas from directly impacting the material tray and affecting the measurement result, refer to Figure 3 , Figure 4 As shown, the handle in this embodiment also includes a wind shield 35 arranged on the inner wall of the ring plate 31 and located in the heating chamber 6. The wind shield 35 is integrated with the handle to reduce the cost of production; at the same time, the design of the wind shield 35 ensures the relative stability of the airflow in the material tray area, thereby improving the test accuracy of the moisture meter.

[0060] Reference Figure 3 As shown, an operating port 351 is provided on the wind shield 35 in this embodiment. Through the design of the operating port 351, when the material tray is not placed in a specific position, the user can fine-tune the position of the material tray through the operating port 351, thereby adjusting the material tray to the specified position.

[0061] Embodiment 2:

[0062] Reference Figure 5 to Figure 7 As shown, the moisture meter in this embodiment includes: a base 1, a heating tray 2, an upper cover 4, a bracket 5, and the handle as described in the first embodiment.

[0063] Among them, the heating tray 2 is arranged on the base 1, and a groove body 21 is recessed on the heating tray 2; the upper cover 4 is rotatably installed on the base 1 through a rotating shaft, and the upper cover 4 and the heating tray 2 enclose a heating bin 6; the bracket 5 passes through the heating tray 2 and the base 1, and the bracket 5 is partially located in the heating bin 6; the inner wall of the ring plate 31 of the handle is arranged inside the heating bin 6, and the outer wall of the ring plate 31 of the handle is arranged outside the heating bin 6, and the handle is used to transfer the material tray to the bracket 5.

[0064] By providing a standardized handle in the moisture meter, the material tray can be reliably and stably transferred to the designated position on the bracket 5; at the same time, the user can be guided to measure the moisture content of the product in the moisture meter with a standardized handle, forming a standardized measurement operation specification, and avoiding inconsistent measurement status and inaccurate test results caused by non-standard operation.

[0065] Specifically, refer to Figure 5 , Figure 6 As shown, the support 5 in this embodiment includes a rod 51 that penetrates the heating tray 2 and the base 1 and support members 52 that are spaced apart along the circumference and located in the heating chamber 6, and a placement plate 33 is provided between two adjacent support members 52. When the material tray is transferred to the support 5 using the handle, interference between the placement plate 33 and the support 5 can be avoided.

[0066] Further, refer to Figure 6 As shown, the first end of the support member 52 in this embodiment is connected to the rod body 51, and a stop plate 521 is provided on the second end of the support member 52. The distance between the stop plate 521 and the axis of the rod body 51 is greater than the outer diameter of the material tray. According to this design, the material tray can be reliably and stably placed on the bracket, and when the material tray is placed on the support member 52, the stop plate 521 can prevent the material tray from being displaced on the support member 52.

[0067] Preferably, in order to prevent the material tray from contacting the placement plate 33 after being transferred to the support member 52, refer to Figure 5 As shown, the upper surface of the support member 52 in this embodiment is higher than the upper surface of the placement portion 331 of the placement plate 33 .

[0068] Furthermore, the height difference between the upper surface of the wind shield 35 and the upper surface of the support 52 in this embodiment is greater than or equal to the height of the material tray. After the handle transfers the material tray to the bracket 5, the material tray is placed on the support 52, and the upper surface of the material tray is lower than the upper surface of the wind shield 35, so as to minimize the direct impact of the gas on the material tray.

[0069] Optionally, in order to facilitate the gas to flow out of or out of the heating chamber 6, refer to Figure 7 Combined with Figure 2 As shown, in this embodiment, an air inlet 7 is formed between the upper cover 4 and the heating tray 2, an air outlet 41 is provided on the upper cover 4, an air flow channel is formed between the air inlet 7 and the air outlet 41, and a vent 8 located in the air flow channel is formed between the upper cover 4 and the handle.

[0070] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0071] The utility model provides a handle and a moisture meter. By setting a limit structure, the handle can be accurately and stably placed at a specific position of a heating tray, so that the material tray can be accurately placed on a bracket, avoiding problems such as handle deformation, improper placement, or interference with the heating tray; and can guide users to measure the moisture content of products in the moisture meter with a standardized handle, form standardized measurement operation specifications, stabilize the test state, and improve the stability of product test results.
