Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection sensors, in particular to a wireless temperature and moisture detection sensor. Background Art
[0002] my country is a major tobacco producer, with an annual inventory of nearly 100 million dan. Tobacco leaves are threshed and re-baked to form tobacco sheets, which need to be aged before they can be used in cigarette manufacturing. The factors that affect the aging are mainly humidity and temperature, which also have a certain impact on the moisture content of tobacco leaves. Jiangsu is located in the middle and lower reaches of the Yangtze River, and the natural environment is humid, especially in high temperature and high humidity seasons. Tobacco leaf moisture control is the main way to ensure the quality of tobacco leaves, reduce the loss of tobacco leaves due to excessive moisture and mildew, and reduce tobacco leaf losses. In particular, the four links of moisture resorption after baking, storage by tobacco farmers, purchase, and storage and maintenance of tobacco leaves in warehouses are particularly critical. If these links are not handled well, the appearance and internal quality of tobacco leaves will be seriously affected. Every year, due to inadequate control of tobacco leaf moisture, tobacco leaves will exceed the limit of moisture, mildew and natural loss, which will cause great economic losses. The moisture control problem has become a "bottleneck" in the purchase and allocation of tobacco leaves. It is urgent to control the moisture content of tobacco leaves, and the moisture content must be controlled between 14% and 15% during the aging process. Careful storage and maintenance of tobacco leaves during storage and strict control of moisture can effectively improve the quality and efficiency of raw material storage and maintenance and ensure the quality of raw materials in storage. Therefore, a wireless temperature and moisture detection sensor is needed, and the sensor will send the collected data to the repeater through wireless technology. Due to the large distribution area of the sensors, a repeater is added for data transfer. The repeater then sends the received data to the serial network converter, and the serial network converter sends the collected data to the server through the network. Finally, the terminal device (mobile phone, platform, computer) can access the server to perform data query and other tasks.
[0003] Existing wireless temperature and moisture detection sensors are usually of fixed length. Therefore, when the sensor is inserted into tobacco for detection, the insertion depth is usually shallow, resulting in failure to detect the innermost tobacco, which in turn easily affects the detection structure.

[0008] Preferably, a motor is provided inside the metal die-casting, and the top of the screw penetrates the protrusion and is embedded in the metal die-casting to be fixedly connected to the output end of the motor.

[0010] Preferably, a limiting ring is sleeved and fixed on the surface of the spiral tube near the top end, and the surface of the limiting ring is slidably connected to the seamless tube.
[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. In the utility model, the motor drives the screw to rotate, the screw rotation drives the spiral tube to move inside the seamless tube, and the movement of the spiral tube drives the moving part to move, which can increase the length of the temperature detector, thereby increasing the detection depth of the temperature sensor, and further improving the detection accuracy.
