Technical Field

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

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. Tea leaves are also known as tea, jiǎ, tea, and tea. Tea beverages made from tea leaves are one of the three major beverages in the world.

[0003] Tea, as a product with high economic value, needs to go through many processes in the production process, among which withering is one of the essential processes. This process makes the tea leaves wilt by spreading them out and drying them in the sun or in the shade. The withering process promotes the activity of fresh leaf enzymes, causing physical and chemical changes inside the tea leaves, thereby improving the quality of the entire tea leaves in terms of aroma, color, etc.

[0004] Due to the characteristics of traditional drying and withering, such as large space occupied and low withering efficiency, the traditional drying processing method has been replaced by withering machines. The withering machine heats the spread tea leaves by passing hot air into the equipment to achieve the withering effect.

[0005] In the above process, the tea leaves need to be monitored so that the moisture content of the tea leaves after withering is in the best state. Usually, a humidity sensor is installed inside the withering machine to monitor the humidity inside the stacked tea leaves so as to control the degree of withering. Since the temperature inside the withering machine is relatively high, the higher temperature will cause more serious wear and tear of the components inside the humidity sensor, thereby reducing the service life of the sensor. Therefore, a tea moisture detection device is proposed to solve the above-mentioned problems. Utility Model Content

[0006] Based on the above description, the utility model provides a tea moisture detection device to solve the problem that the service life of the existing humidity sensor is easily reduced due to high temperature in the withering machine.

[0012] Furthermore, the pipe clamps on the upper and lower sides are connected to each other by screws and nuts, and are respectively arranged on both sides of the gas pipeline.

[0013] Furthermore, the protective cover comprises a cover body, the outer surface of the cover body is provided with through holes, and the interior of the cover body is provided with a partition.

[0014] Furthermore, the protective cover is threadedly connected to the hollow threaded barrel and is interconnected with the hollow threaded barrel, and the humidity sensor is arranged between the partition and the hollow threaded barrel.

[0016] Furthermore, the ventilation member is arranged at both ends of the gas pipeline, and includes an outer shell, and a heat dissipation fan is arranged inside the outer shell.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. The utility model is provided with a mounting frame, an air pipeline, an air cavity block, a protective cover and other components.

[0030] Please refer to the figure Figure 1 , Figure 2 , Figure 4 and Figure 5 , a tea moisture detection device, comprising:

[0031] withering machine 1; and

[0032] The gas transmission structure includes a gas transmission pipeline 2, a gas cavity block 3, a mounting frame 7 and a ventilator 8, wherein:

[0033] The gas delivery pipeline 2 is communicated with the gas cavity block 3, and the gas delivery pipeline 2 includes a pipeline body 21. A guide groove 22 is provided on a side of the pipeline body 21 away from the withering machine 1. A sealing strip 6 is provided inside the guide groove 22. The sealing strip 6 is a T-shaped sealing strip.

[0034] The air cavity block 3 comprises a bottom block 31 and a top block 32, both ends of the bottom block 31 and the top block 32 are provided with pipe clamps 33, the top end of the top block 32 is provided with a hollow threaded tube 34, the pipe clamps 33 on the upper and lower sides are connected to each other by screws and nuts, and are respectively provided on both sides of the gas pipeline 2;

[0035] A mounting frame 7 is provided outside the gas pipeline 2, and the mounting frame 7 is an L-shaped plate, and the mounting frame 7 is in contact with two side walls of the withering machine 1;

[0036] The ventilator 8 is disposed at both ends of the gas pipeline 2, and includes a shell, and a cooling fan is disposed inside the shell;

[0037] Based on the above, the mounting frame 7 cooperates with the withering machine 1 so that the gas pipeline 2 can be stuck inside the withering machine 1, thereby realizing the fixation of the gas transmission structure, wherein the gas pipeline 2 is arranged between the top block 32 and the bottom block 31, and the top block 32 and the bottom block 31 are connected to each other by means of screws and nuts. In this process, the gas pipeline 2 is clamped by the pipe clamp 33 to realize the connection and fixation of the gas pipeline 2 and the air cavity block 3.

[0038] like Figure 2 and Figure 3 As shown, a protective cover 5 is arranged at the top of the air cavity block 3, the protective cover 5 comprises a cover body 51, the outer surface of the cover body 51 is provided with a through hole 52, a partition plate 53 is arranged inside the cover body 51, the protective cover 5 is threadedly connected with the hollow threaded cylinder 34, and is communicated with the hollow threaded cylinder 34, and the humidity sensor 4 is arranged between the partition plate 53 and the hollow threaded cylinder 34;

[0039] a humidity sensor 4, which is arranged between the protective cover 5 and the air cavity block 3;

[0040] Based on the above, the setting of the protective cover 5 has the effect of separating the tea leaves and the humidity sensor 4, so that the humidity sensor 4 will not be squeezed by the tea leaves, indirectly extending the service life. The setting of the through hole 52 allows the air inside the withering machine 1 to enter the interior of the protective cover 5 and contact the humidity sensor 4.

[0041] In actual use of this embodiment, by placing the humidity sensor 4 at the top of the hollow threaded cylinder 34, the cable of the humidity sensor 4 is extended into the interior of the air cavity block 3, and the cable is extended from the side of the air cavity block 3, and then the air cavity block 3 and the gas pipeline 2 are connected to each other by screws and nuts. The connection process makes the cable extend into the interior of the guide groove 22 and run along the guide groove 22;

[0042] The gas pipeline 2 and the air cavity block 3 are placed inside the withering machine 1 through the mounting frame 7, that is, Figure 1 In the state, the air delivery structure is closely attached to the side wall of the withering machine 1 under the action of gravity. When the tea leaves are spread inside the withering machine 1, the tea leaves are piled up, and the protective cover 5, the humidity sensor 4 and other structures are buried in the tea leaves;

[0043] When the tea leaves are withered, the humidity sensor 4 can monitor the humidity inside the tea leaves. Since the moisture in the air is precipitated from the tea leaves during withering, the moisture content of the tea leaves can be indirectly understood by detecting the humidity of the environment.

[0044] When the withering machine 1 generates heat during operation, the cooling fan inside the ventilation piece 8 is energized to allow external cold air to enter the interior of the gas pipeline 2, so as to achieve the effect of dissipating heat for the humidity sensor 4, thereby avoiding the high temperature environment from causing greater damage to the internal components of the humidity sensor 4, thereby increasing the service life of the humidity sensor 4.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
