In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0030] Example:
[0031] like Figure 1-6 As shown, this embodiment provides an artificial rime landscape device, including an appearance box, a refrigeration device, an atomization device, an electronic control device 28 and a rime tree 1, wherein the refrigeration device is used to continuously provide cold air to maintain the low temperature of the rime growth environment; the atomization device is used to provide water vapor to maintain the humidity of the rime growth environment; the rime tree 1 uses a fresh potted tree as a carrier for rime generation; the appearance box plays a role of heat preservation and moisture retention and a carrier.
[0032] The interior of the exterior box is divided into two layers by the insulation partition 2, the lower layer is the main box 3, and the upper layer is the transparent cover 4; the refrigeration device, the atomization device and the electric control device 28 electrically connected to the two are installed in the main box 3, the trunk of the rime tree 1 is located in the transparent cover 4, and the root is located in the main box 3; the refrigeration device provides low-speed cold air to the transparent cover 4 on the upper layer, and delivers windless cold air to create a "windless" low-temperature environment; the center of the insulation partition 2 is opened There is a rime tree planting hole, and a spray plate 5 with spray holes is installed on the outer circle of the rime tree planting hole; a rime tree planting carrier 6 is installed at the position corresponding to the rime tree planting hole in the main box 3, and an atomized water vapor conveying box 7 is installed on the outer circle of the rime tree planting carrier 6. The atomized water vapor conveying box 7 is fixedly connected to the bottom surface of the insulation partition 2, and the top opening of the atomized water vapor conveying box 7 corresponds to the spray plate 5 installed on the insulation partition 2, and the cold steam outlet of the atomizing device is connected to the atomized water vapor conveying box 7.
[0033] Further, such as Figure 6 As shown, the transparent cover 4 includes multiple layers of sealed glass inside and outside, the innermost layer is the inner layer of perforated glass 8; a plurality of micropores 9 are attached to the entire glass of each inner layer of perforated glass 8, each micropore 9 is opened obliquely upward in the direction close to the rime tree 1, and an air inlet 10 is opened at the bottom of the inner layer of perforated glass 8; an air vent 11 is installed on the top surface of the thermal insulation partition 2, one side of the air vent inlet is downwardly connected to the cold air outlet of the refrigeration device, and one side of the air vent outlet is inserted into the air inlet 10 at the bottom of the inner layer of perforated glass 8, and extends out from the micropores 9 at the top.
[0034] The utility model provides a plurality of micropores 9 with the same upward slope, and the micropores 9 are finally connected to the air outlet of the refrigeration device through a small passage in the middle of the glass, so as to transmit "windless" cold air to the environment where the upper layer of rime grows, thereby creating a "windless" environment.
[0035] At the same time, the wind speed of cold air provided by the refrigeration device to the transparent cover 4 is limited to 0-0.2m / s, which not only disturbs the environment for the growth of upper rime, but also does not form direct blowing of cold air, avoiding frost on the inner wall of the inner glass.
[0036] Furthermore, the main chassis 3 is a sealed square chassis, and the transparent cover 4 is a sealed quadrangular pyramid glass appearance box, which is made of three layers of sealed glass inside and outside, specifically an outer layer of glass 12, a middle layer of glass 13 and an inner layer of perforated glass 8, which can achieve a good thermal insulation effect.
[0037] Specifically, the device of the utility model uses a sealed chassis shell, and the upper shell of the product uses a sealed vacuum triple-layer glass, each layer of glass is sealed with a sealing strip and glass glue, and four triple-layer glasses are used to form a quadrangular pyramid glass cover. A plurality of upwardly inclined micropores 9 are attached to the entire glass of each inner layer of perforated glass 8, and the outer opening of the micropore 9 is small and the inner hole is large, gradually increasing from the outside to the inside, and the upper layer of the inner hole edge is made into a convex cut, which is conducive to relieving the wind speed and making the wind direction blow upward along the inner wall of the inner layer of perforated glass 8, avoiding direct blowing of cold air and frost on the inner wall of the inner layer of glass.
[0038] The refrigeration device in the utility model mainly includes a compressor 14, a condenser 15, and an evaporator 16. These three components are connected in sequence by pipes to form a closed system. There are two groups of evaporators 16, which are respectively installed on both sides of the bottom of the thermal insulation partition 2. The evaporator fan (specifically, the impeller fan 17) sends the cold air in the evaporator 16 to the cold air outlet of the evaporator 16, and the cold air outlet of the evaporator 16 is connected to the corresponding ventilation duct inlet above it. A drying filter 18 and a capillary 19 for adjusting the refrigerant flow rate and flow rate are also installed between the condenser 15 and the corresponding evaporator 16.
[0039] The atomizing device in the utility model comprises a water tank 20, a water tank water filling port 21 is provided on the upper part of the water tank 20, an atomizing pool 22 is installed below the water tank 20, an atomizing pool water level control valve 23 is installed on the connecting pipeline between the atomizing pool 22 and the water tank 20, and the electric control device 28 can adjust the water level in the atomizing pool 22 by controlling the atomizing pool water level control valve 23; an ultrasonic transducer 24 is installed inside the atomizing pool 22, and a fan 25 capable of transporting the water vapor in the atomizing pool 22 to the outside is installed outside, and an atomizing conduit 26 is connected to the top of the atomizing pool 22, and the atomizing conduit 26 extends upward and its top steam outlet is connected to the atomizing water vapor transport box 7.
[0040] At the same time, a water vapor cooling device 27 is also installed on the periphery of the top steam outlet of the atomizing duct 26. The water vapor cooling device 27 uses a small-volume evaporator. A portion of the refrigerant to be flowed into the evaporator 16 will flow into the refrigerant inlet of the water vapor cooling device 27 through a branch pipe, and then flow back to the compressor 14 from the refrigerant outlet of the water vapor cooling device 27; the water vapor cooling device 27 is used to cool the water vapor generated by the atomizing device, and control the water vapor temperature in the atomizing duct 26 to maintain at 2°C-5°C, so that the temperature of the water vapor entering the upper layer of the rime growth environment is low enough, so as not to bring additional heat to the growth environment, and the low-temperature water vapor is also easier to crystallize.
[0041] In a further specific embodiment, a temperature sensor and a humidity sensor are installed in the transparent cover 4, and the electric control device 28 is provided with a temperature controller electrically connected to the temperature sensor and a humidity controller electrically connected to the humidity sensor.
[0042] The temperature sensor is used to monitor the ambient temperature of the upper layer of rime growth in real time and transmit the signal to the temperature controller; the temperature controller is used to receive the signal of temperature change. When the internal temperature of the device is lower than or higher than the set temperature, the refrigeration device starts or stops refrigeration.
[0043] More specifically, the internal temperature of the transparent cover 4 is controlled between -10°C and -30°C. Rime is easily generated in this temperature range. More preferably, the optimal temperature for generating rime is -17°C.
[0044] The humidity sensor is used to monitor the environmental humidity of the upper layer of rime growth in real time and transmit the signal to the humidity controller; the humidity controller is used to receive the signal of humidity change. When the humidity inside the device is lower than or higher than the set humidity, the atomization device starts or stops atomizing.
[0045] More specifically, the internal humidity range is set to 45%-90%, in which rime is easily generated. The optimal humidity range for generating rime is 70%-80%, and the best humidity is 75%.
[0046] The utility model uses control and sensing technology to adjust environmental parameters for the growth of rime, such as the temperature and humidity of ambient air and the flow conditions of humid air, to simulate the low-temperature and high-humidity environment formed by artificial rime, thereby ensuring the continuation of the rime landscape.
[0047] The working principle of this utility model:
[0048] The formation of ice crystals requires a low temperature environment; in the artificial rime landscape device, a low temperature environment of -10°C to -30°C is created by a refrigeration device. When the temperature inside the device is higher than -10°C, the temperature sensor detects the ambient temperature and transmits a signal instruction to the temperature controller. The temperature controller starts the refrigeration device to maintain the low temperature of the rime growth environment. When the temperature inside the device is lower than -30°C, the temperature sensor transmits a signal instruction to the temperature controller, and the temperature controller stops the operation of the refrigeration device.
[0049] The formation of ice crystals also requires that the environment where the upper layer of rime grows has air flow, but it is not suitable to have large air flow; in the artificial rime landscape device, the air outlet speed of the refrigeration device is set to 0-0.2m / s by controlling the rotation speed of the impeller fan 17 in the evaporator 16. The vent pipe 11 is connected to the cold air outlet position of the evaporator 16, and the vent pipe 11 is inserted into the oblique micropores 9 on the inner layer of ...
[0050] The formation of ice crystals also requires that the environmental humidity for the growth of the upper layer of rime reaches the optimal humidity of 75%. In the artificial rime landscape device, water is added to the water tank 20, and the water in the water tank 20 is injected into the atomizing pool 22 through the atomizing pool water level control valve 23. When the water level is flush with the atomizing pool water level control valve 23, the water injection is stopped, and the water is converted into water vapor through the ultrasonic transducer 24. The water vapor is transported to the atomizing water vapor transport box 7 through the atomizing conduit 26, and then the water vapor is sprayed out through the upper spray plate 5. The water vapor cooling device 27 is used at the atomizing conduit 26 to cool the atomized water vapor, so that the environment for the growth of the upper layer of rime meets the humidity requirements for the formation of artificial rime. When the ambient humidity for the growth of the upper layer of rime is less than 70%, the humidity sensor detects the ambient humidity and transmits a signal command to the humidity controller, which starts the atomization device to maintain the internal humidity environment. When the ambient humidity for the growth of the upper layer of rime is greater than 80%, the humidity sensor transmits a signal command to the humidity controller, which stops the operation of the atomization device.
[0051] The rime tree 1 in the utility model uses a young and fresh potted pine tree. The fresh potted pine tree has a large amount of impurity particles, which is conducive to the generation of ice crystal nuclei. In addition, the utility model places the root of the rime tree 1 in the lower main box 3 of the device, and places the branches of the rime tree 1 in the upper transparent cover 4. The root and branches of the rime tree 1 are respectively placed in the lower and upper layers of the device, separated by a heat-insulating partition 2 in the middle, which also fully guarantees the activity of the pine tree. At the same time, the upper and lower layers of the chassis are separated by a heat-insulating board, which also fully guarantees the low temperature and high humidity environment of the upper layer of the chassis.
[0052] The main control board in the electric control device 28 of the utility model receives signal instructions from the temperature sensor and the humidity sensor, and transmits control signal instructions to the temperature controller and the humidity controller. The fan controller is used to adjust the speed of the impeller fan 17. The LED light is connected to the main control board. The temperature controller controls the start and stop of the refrigeration device, and the humidity controller controls the start and stop of the atomization device.
