Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea preservation equipment, in particular to a tea cabinet. Background Art
[0002] People have loved drinking tea since ancient times, and tea has become an indispensable part of many people's lives. Whether at home or in the company, people always need tea leaves when drinking tea, and different types of tea require different temperature and humidity conditions for storage. In particular, the high temperature and high humidity environment in the south is not easy to manage and is prone to mold, while the dry weather in the north in winter makes it difficult to store tea leaves.
[0003] The traditional method is to store tea leaves in a household refrigerator or freezer. The storage environment of the refrigerator or freezer cannot control the temperature and humidity, so it cannot store tea leaves of different types. In addition, for merchants selling tea, tea leaves are the link between merchants and customers. How to preserve the quality of tea leaves and design a tea cabinet that can create a storage environment for different types of tea leaves can become a link between merchants and customers, increase the viscosity between merchants and customers, and facilitate the sales of tea leaves. It can also form a fixed customer base and facilitate sales. Utility Model Content

[0074] The tea cabinet in this design is different from the traditional freezer (which uses a freezer to store tea). An ecological environment suitable for teas with different storage conditions is established in the tea cabinet. For example, the storage conditions of some teas are as follows:
[0075] (1) Raw Pu'er tea: temperature 20-30℃, humidity 45-65%.
[0076] (2) Pu'er Ripe Tea: temperature 25-35℃, humidity 50-70%.
[0077] (3) Fuding White Tea: temperature 18-28℃, humidity 40-65%.
[0078] (4) Black tea, oolong tea: temperature 10-25℃, humidity 30-50%.
[0079] Therefore, in the present design, grille windows 1061 are provided on both sides of the rear surface of the partition 106; a back panel 104 is provided at the rear of the storage cavity 101, and a gap compartment 10 is left between the back panel 104 and the rear surface of the tea cabinet 1, and a plasma generator 12 is installed in the middle of the gap compartment 10, and the plasma generator 12 is connected to a first nozzle 13 installed in the middle of the surface of the back panel 104. A circuit board is arranged at the top of the gap bin; a main control unit is arranged on the circuit board, one end of the main control unit is respectively connected to the AC-DC conversion unit, the DC-DC conversion unit, and the cooling and heating unit, and the other end of the main control unit is connected to the MAX485 control unit and the output drive IO unit; the MAX485 control unit is respectively connected to the screen interface, the output interface, the serial port interface, the plasma generator interface, the negative oxygen ion sensor interface, and several reserved interfaces; the main control unit is a PLC controller 17, the screen interface is connected to the display screen 3, the plasma generator interface is connected to the plasma generator 12, the negative oxygen ion sensor interface is connected to the negative oxygen ion sensor 15, and several reserved interfaces are respectively connected to the PM2.5 sensing module 16, the seven-in-one air quality sensor 18, and the fresh air module 19.
[0080] The PLC controller 17 is used to control the negative oxygen ion sensor 15, the PM2.5 sensor module 16, the seven-in-one air quality sensor 18, and the fresh air module 19. Among them, the plasma generator 12 generates negative oxygen ions, and the negative oxygen ion sensor 15 can sense the number of negative oxygen ions, so as to better monitor the level of negative oxygen ions; in addition, the PM2.5 sensor module can detect the PM2.5 particle status in the tea cabinet in real time, and the seven-in-one air quality sensor 18 can detect the temperature and humidity in real time, and the PLC controller is used to control the compressor 9 to achieve heating or cooling. The water tank 7 and the wet film humidification device installed in the water tank 7 are used to achieve wet film humidification.
[0081] Thereby humidity control is realized. In addition, a water level sensor 8 is installed on one side of the water tank 7, which mainly prevents the problem of low water level in the water tank 7.
[0082] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
