Description

Technical Field

[0001] The utility model relates to the technical field of flower breeding, in particular to a soil temperature and humidity controller. Background Art

[0002] Products for constant temperature control and humidity control in flower cultivation are designed to prevent flowers from freezing to death or withering prematurely due to cold weather. At the same time, in flower cultivation, the humidity is too low or the flowers lack water, which may cause the flowers to dry up and die. Based on this, there is a need for products that can effectively provide constant temperature heating to the flower soil to ensure that the flowers grow normally within the set temperature range.

[0003] For example, the authorization announcement number "CN215180174U" is named as an agricultural planting soil temperature and humidity monitoring device. Although an internal threaded cylinder and a support device are provided, the support height of the support device is adjusted by rotating the internal threaded cylinder, and the fixing bolt is removed from the surface of the connecting rod to adjust the length of the support device, but the existing agricultural planting soil temperature and humidity monitoring device monitors the temperature and humidity of the soil planted in a large area in rural areas. Flowers are generally grown in flower pots, so it is necessary to control the temperature and humidity of a small amount of soil in the flower pots. The flower plants planted in flower pots are small, and the soil in the flower pots is also relatively shallow. Therefore, after the overly long temperature sensor and humidity sensor are inserted into a too shallow flower pot, they will often become loose and fall over due to insufficient fixation, thereby affecting the temperature and humidity control effect of the agricultural planting soil temperature and humidity monitoring device.

[0004] At the same time, the existing agricultural soil temperature and humidity monitoring device needs to heat the flowers planted in the flowerpots under a low temperature environment when controlling the temperature and humidity of the flowers, so that the growth temperature of the flowers is maintained within a certain appropriate range. However, the common heating method at this stage is to heat the soil with the temperature generated by the heating box at the bottom. Most of the heat heated by the heating box through the flowerpot will be absorbed by the flowerpot, and the soil temperature rising effect is not obvious enough. In addition, the inside of the flowerpot needs to be irrigated with water, and the excess water needs to be discharged at the bottom of the flowerpot. The discharged water will directly contact the bottom heating box, which will cause the heating box to age and be damaged over time, ultimately reducing the service life of the agricultural soil temperature and humidity monitoring device.

[0011] Preferably, a lateral heating and water-prevention structure is provided on the inner side of the base;

[0038] Irrigation waterproofing and efficient heating structure of soil temperature and humidity controller:

[0039] When the soil flower pot 2 is placed in the positioning groove 71, in order to better heat and maintain the temperature, the threaded rods 73 on both sides are manually twisted to rotate on both sides of the positioning groove 71, so that the threaded rods 73 will drive the two threaded blocks 74 connected by threads to push inward, and then the pushing plate 75 will be driven down by the threaded blocks 74 to make the heating box 76 fit on both sides of the soil flower pot 2. In this way, the heating box 76 can avoid irrigation water and can also quickly heat the upper soil from both sides, using a more efficient and rust-proof heating and insulation method to increase the service life of the soil temperature and humidity controller.

[0040] Flower soil temperature and humidity control working process:

[0041] The ideal temperature range of the soil temperature for flower cultivation is: 15℃ to 25℃. 15℃ is set as the heating start temperature, and 25℃ is designed as the heating stop temperature. The temperature and humidity controller transmits the temperature of the soil in the flowerpot to the controller MCU based on the temperature sensor 63. When the soil temperature drops to 15℃, the MCU issues a command, the heating indicator light turns on, and the output voltage is given to the heating box to make it heat up. When the soil temperature reaches 25℃, the temperature sensor 63 transmits the temperature of the soil in the flowerpot to the controller MCU. The MCU issues a command, and the output voltage turns off the voltage output of the heating box, the heating indicator light turns off, and the heating plate stops heating. In this way, the temperature is controlled between 15℃ and 25℃, and the cycle works;

[0042] The ideal humidity range of the soil for flower cultivation is 50% to 70%. Set 50% as the humidification start humidity and 70% as the humidification stop humidity. The temperature and humidity controller transmits the humidity in the soil of the flower pot to the controller MCU according to the fork humidity sensor 62. When the soil humidity drops to 50%, the MCU issues a command, the humidification indicator light turns on, and the output voltage is given to the humidifier to make it humidify. When the soil humidity reaches 70%, the fork humidity sensor 62 transmits the humidity in the soil of the flower pot to the controller MCU, and the MCU issues a command to turn off the humidifier voltage output, the humidification indicator light turns off, and the humidifier stops heating. In this way, the humidity is controlled between 50% and 70% and works in a cycle.
