Description

Technical Field

[0002] Display cabinets are protective stands for displaying merchandise. Colors can be chosen to suit your store's decor. With their sturdy structure, easy assembly and disassembly, and convenient transportation, display cabinets are widely used in company showrooms, exhibitions, department stores, and advertising spaces. They are also widely used in industries such as handicrafts, gifts, jewelry, mobile phones, eyewear, watches, tobacco, alcohol, and cosmetics.

[0003] Currently, tobacco display cabinets are commonly used in shopping malls to store tobacco. Because large amounts of tobacco need to be stored for long periods of time, tobacco easily absorbs moisture from the air, causing it to deteriorate and affecting its quality for sale. The air temperature and humidity vary at various locations within the tobacco display cabinet. Therefore, the detection results of a single, fixed, independent thermometer and hygrometer are inaccurate, and the environment inside the tobacco display cabinet cannot be effectively monitored. This results in inadequate temperature and humidity management within the tobacco display cabinet, which can easily cause tobacco to deteriorate. To overcome these problems, we propose a thermometer and hygrometer for tobacco display cabinets that monitors temperature and humidity, allowing for timely adjustment to prevent tobacco deterioration.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0023] See also Figures 1 to 6The utility model relates to a thermometer and hygrometer for a tobacco display cabinet, comprising several auxiliary thermometers and hygrometers 2 evenly distributed inside a tobacco display cabinet body 3, and a main thermometer and hygrometer 1 wirelessly connected to each of the auxiliary thermometers and hygrometers 2 by electrical signals. The main thermometer and hygrometer 1 comprises a bottom cover 11, a surface cover 12, a control component 13, a first temperature sensor 14, and a first humidity sensor 15. The surface cover and the bottom cover are connected by a snap fastener. The surface cover is provided with an opening, and the opening is provided with a control component 13. The surface cover is also provided with a control button for operating the control component 13. The first temperature sensor 14 and the first humidity sensor 15 are provided below the control button, and a power supply compartment is provided on the bottom cover; the auxiliary thermometers and hygrometers 2 are provided with a second temperature sensor 21 and a second humidity sensor 22; several of the auxiliary thermometers and hygrometers 2 are distributed at the bottom corner position, top corner position or center position of the inner side wall of the tobacco display cabinet body 3.

[0024] When in use, first divide the 9 auxiliary thermometers and hygrometers 2 into three groups, with 3 auxiliary thermometers and hygrometers 2 in each group, and distribute them in the upper, middle and lower parts of the tobacco display cabinet body 3 according to the bottom corner position, the top corner position or the center position, so as to fully cover the interior of the tobacco display cabinet body 3. The temperature and humidity data detected by each auxiliary thermometer and hygrometer 2 are uniformly transmitted to the main thermometer and hygrometer 1 for processing and display, so as to improve the temperature and humidity detection results, and effectively grasp the environment inside the tobacco display cabinet, so that the temperature and humidity management inside the tobacco display cabinet is in place, and tobacco deterioration due to lack of management and investigation is avoided. Specific embodiment 1

[0025] The optimal temperature range for tobacco storage is around 25°C. Temperatures detected by the auxiliary thermo-hygrometers 2 that are too high or too low can affect the quality of the cigarettes, causing them to become damp and mold to grow, or drying out, affecting their taste and burning properties. Specifically, the control component 13 controls the required temperature, monitoring the appropriate storage temperature at 22-26°C through the auxiliary thermo-hygrometers 2. This maintains a stable storage temperature, maintaining high tobacco quality and facilitating long-term storage and use at various tobacco retailers' counters. Specific embodiment 2

[0026] The relative humidity of tobacco storage should be controlled at around 60%. If the humidity data detected by each auxiliary thermo-hygrometer 2 is too high, it means that the cigarettes are easily damp, so dehumidification is required in a timely manner. If the humidity data detected by each auxiliary thermo-hygrometer 2 is too low, it means that the tobacco may become dry, so humidification is required in a timely manner. The control component 13 controls the required corresponding humidity control. The appropriate humidity range monitored by each auxiliary thermo-hygrometer 2 is 55%-65%. At this time, the storage humidity of the tobacco can be kept stable, maintaining the high quality of the tobacco, and facilitating long-term storage and use at the retail counters of various tobacco retailers.

[0027] Furthermore, the control component 13 includes a main control chip, an MCU control circuit and an LED display screen, wherein the MCU control circuit includes an MCU chip CX32L003 and its peripheral circuits, so as to efficiently process temperature and humidity detection data and improve data detection accuracy.

[0028] Furthermore, a power supply is provided in the power supply compartment, and the power supply includes two dry batteries, lithium batteries or nickel-hydrogen batteries, a positive electrode sheet, a positive and negative connecting sheet and a negative electrode sheet arranged at the positive and negative poles of the two batteries. The two dry batteries output a 4.5V voltage to power the circuit, or the two lithium batteries output a 5V voltage to power the circuit, or the two nickel-hydrogen batteries output a 5V voltage to power the circuit.

[0029] Furthermore, the first temperature sensor 14 and the second temperature sensor 21 are selected from the group consisting of a platinum resistance temperature sensor, a thermocouple temperature sensor, and a thermistor temperature sensor. These temperature sensors have the advantages of high precision, good stability, fast response speed, ease of use, and simple maintenance.

[0030] Furthermore, the first humidity sensor 15 and the second humidity sensor 22 are selected from the group consisting of a capacitive humidity sensor, a thermocouple humidity sensor, and a capacitive humidity sensor. These humidity sensors have the advantages of high precision, automatic calibration, and ease of installation and maintenance.

[0031] Specifically, a transparent cabinet door 31 is installed on the upper part of the front shell of the tobacco display cabinet body 3, a manual recording board 32 is movably connected to the side area adjacent to the transparent cabinet door 31, and a cabinet door handle 33 is fixed at the edge of the transparent cabinet door 31.

[0032] More specifically, the manual recording board 32 is a flat board for repeated writing, and can be used to record the amount of tobacco stored.

[0033] The utility model adopts an omnidirectionally arranged thermometer and hygrometer structure to replace a single fixed thermometer and hygrometer, thereby expanding the effective range of detecting the temperature and humidity inside the tobacco display cabinet, making the detection of temperature and humidity more sufficient and effectively improving the detection accuracy of temperature and humidity.
