Description

Technical Field

[0001] This application relates to the field of tobacco box temperature and humidity detection technology, and in particular to a low-power wireless sensor monitoring system for tobacco box temperature and humidity. Background Technology

[0002] Moisture content detection in tobacco warehouses is a key parameter for controlling the temperature and humidity environment during tobacco storage. At this stage, the moisture content of the tobacco leaves needs to be maintained within a stable "safe range," typically 12%-15%. Environmental factors primarily affect the following: in high humidity environments, tobacco leaves absorb moisture from the air, increasing their moisture content. When the moisture content exceeds 15%, mold will multiply rapidly, causing the tobacco leaves to rot, produce a musty smell, and become completely unusable. Excessive fermentation leads to excessively dark coloring or even carbonization. A damp environment also easily breeds pests such as tobacco beetles.

[0003] In low-humidity environments, tobacco leaves release moisture into the dry air. When the moisture content is below 10%, the leaves become brittle, lose their elasticity, and are easily broken during handling and processing, resulting in a significant decrease in yield. Excessive dryness causes the loss of volatile aroma compounds. High temperatures accelerate the process of moisture absorption or release, while also accelerating changes in chemical composition and the activity of insects and molds.

[0004] Therefore, tobacco leaves need to be tested for temperature and humidity regularly during storage. The existing technology mainly uses air intake holes to test temperature and humidity, but this method cannot be used to test different locations of the tobacco leaves, which leads to deviations in the test results.

[0025] Terminology explanation: such as Figures 1 to 6As shown, a low-power wireless sensor monitoring system for temperature and humidity in a cigarette box includes a housing 1. Squeezing cylinders 4 are installed on both sides inside the housing 1. Squeezing plates 15 are slidably connected inside the squeezing cylinders 4. Electric push rods 3 are installed on both sides outside the housing 1. The movable ends of the electric push rods 3 pass through the housing 1 and connect to the squeezing plates 15. A sealing plate 16 is installed on the side of the squeezing cylinders 4 away from the squeezing plates 15. Multiple suction cylinders 6 are arranged concentrically and slide in contact with each other on the side of the sealing plate 16 away from the squeezing plates 15. The outermost suction cylinder 6 is slidably connected to the annular inner surface of the squeezing cylinder 4, with the suction cylinder 6 facing the sealing plate 16. Multiple circular grooves 24 are provided. A connecting cylinder 17 is slidably connected in the circular grooves 24 inside the air intake cylinder 6. The space formed by the connecting cylinder 17, the extrusion plate 15, and the sealing plate 16 is in communication. A sealing ring 23 is installed on the side of the annular surface of the connecting cylinder 17 away from the sealing plate 16. The sealing ring 23 is slidably connected in the circular grooves 24. A horizontal tube 25 is installed on the annular inner surface of the air intake cylinder 6. One end of the horizontal tube 25 is in communication with the circular grooves 24. The end of the horizontal tube 25 away from the circular grooves 24 is in communication with the adjacent connecting cylinder 17 inside the air intake cylinder 6. A support ring 22 is installed on the annular inner surface of the air intake cylinder 6. The upper surface of the support ring 22 is connected to the connecting cylinder 17 set on the inner side.

[0026] An exhaust pipe 9 is installed at the top inside the housing 1. Multiple exhaust holes 10 are opened on the annular surface of the side of the exhaust pipe 9 facing the inside of the housing 1. A connecting pipe 7 is installed at the end of the exhaust pipe 9. A temperature and humidity sensor is installed inside the connecting pipe 7. A second one-way valve 8 is installed inside the connecting pipe 7. The end of the connecting pipe 7 away from the exhaust pipe 9 is connected to the space on the side of the extrusion plate 15 away from the sealing plate 16. A storage battery 2 is installed on the outside of the housing 1. The storage battery 2 provides power to the temperature and humidity sensor and the electric push rod 3.

[0027] By setting multiple suction cylinders 6 on the side of the sealing plate 16 away from the extrusion plate 15, when the extrusion plate 15 moves toward the sealing plate 16, it squeezes the air between the sealing plate 16 and the extrusion plate 15, thereby pushing the multiple suction cylinders 6 out of the extrusion cylinder 4 in sequence. This allows the multiple suction cylinders 6 to draw air from different positions inside the chamber 1, thereby uniformly drawing air from the chamber 1 and improving the accuracy of detecting the air temperature and humidity inside the chamber 1.

[0028] Both the sealing plate 16 and the extrusion plate 15 have a circular hole 21 on their opposite sides. A connecting pipe 11 is installed in the circular hole 21 in the sealing plate 16. A third one-way valve 20 is installed in the connecting pipe 11. The end of the connecting pipe 11 away from the sealing plate 16 is slidably connected to the circular hole 21 on the extrusion plate 15. An installation block 19 is installed in the connecting hole. A spiral rod 14 is rotatably connected to the side of the installation block 19 away from the third one-way valve 20. A rotating blade 18 is installed on the side of the spiral rod 14 close to the installation block 19. A spiral block 13 is spirally connected to the end of the spiral rod 14 away from the installation block 19. A connecting rod 12 is installed on the side of the spiral block 13 facing the extrusion plate 15. The end of the connecting rod 12 away from the spiral block 13 is connected to the extrusion plate 15.

[0029] By installing a connecting pipe 11 between the extrusion plate 15 and the sealing plate 16, and installing an air intake structure consisting of an installation block 19, a spiral rod 14, a rotating blade 18 and a connecting rod 12 inside the connecting pipe 11, air is drawn in from the suction cylinder 6 towards the side of the extrusion plate 15 away from the sealing plate 16 when the extrusion plate 15 moves toward the sealing plate 16. This increases the amount of air entering the exhaust cylinder 9 and further increases the accuracy of detecting the air temperature and humidity inside the housing 1.

[0030] Working principle: When the electric drive is started, the electric drive moves the extrusion plate 15 closer to the sealing plate 16. At this time, the space between the extrusion plate and the sealing plate 16 is reduced, so that the air that was originally between the extrusion plate 15 and the sealing plate 16 enters the circular groove 24 in the outermost air intake 6 through the connecting cylinder 17. At the same time, the outermost air intake 6 moves out of the extrusion cylinder 4, and air is drawn into multiple air intakes 6 through the first one-way valve 5.

[0031] When the circular groove 24 inside the outermost suction cylinder 6 is connected to the horizontal pipe 25, the air that enters the outermost suction cylinder 6 through the outermost connecting cylinder 17 then enters the circular groove 24 on the inner suction cylinder 6 through the horizontal pipe 25, pushing the suction cylinder 6 to continue moving outward. This pushes inward until all the suction cylinders 6 can no longer move. After all the suction cylinders 6 have sucked in air, the movable end of the electric push rod 3 is restarted to retract, and the extrusion plate 15 is moved away from the sealing plate 16. This causes the suction cylinders 6 to move back towards the sealing plate 16, and the air sucked in by the suction cylinders 6 enters the extrusion plate 15 away from the sealing plate 16 through the connecting pipe 11, then enters the exhaust pipe 9 through the connecting pipe 7, and is then discharged back into the housing 1. The air passes through the temperature and humidity sensor and is detected by the temperature and humidity sensor.

[0032] When the extrusion plate 15 moves toward the sealing plate 16, the extrusion plate 15 drives the spiral block 13 to move through the connecting rod 12. The movement of the spiral block 13 drives the spiral rod 14 to rotate. The rotation of the spiral rod 14 drives the rotating blade 18 to rotate and draw in air from multiple air intake cylinders 6, thereby increasing the amount of air entering the exhaust cylinder 9 and further increasing the accuracy of the detection of air temperature and humidity inside the housing 1.

[0033] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
