DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0035] like Figures 1-16 As shown: This invention includes a microprocessor component 1, an ambient temperature and humidity sensor 2, a power supply 3, a cooling system 4, a water storage tank 6, a temperature control component, a soil moisture detector 12, a forced irrigation pump 16, a water distribution pipeline 18, and a needle-shaped water-saving drip irrigation device 19. The power output terminal of the power supply 3 is connected to the power input terminals of the microprocessor component 1, the cooling system 4, the temperature control component, and the forced irrigation pump 16, respectively. The signal output terminals of the ambient temperature and humidity sensor 2 and the soil moisture detector 12 are connected to the signal input terminal of the microprocessor component 1. The control signal output terminal of the microprocessor component 1 is electrically connected to the temperature control component and the forced irrigation pump 16. The drain terminal of the cooling system 4 is connected to the inlet terminal of the water storage tank 6. The temperature control component is disposed inside the water storage tank 6. The drain terminal of the water storage tank 6 is connected to the needle-shaped water-saving drip irrigation device 19 in sequence through the forced irrigation pump 16 and the water distribution pipeline 18.

[0036] According to botanical research, when plants are irrigated with cold water, they may mistakenly perceive a change in season, leading to slowed or even stopped growth. When the water temperature is close to the ambient temperature, plants can grow normally according to seasonal changes. However, because the condensate water temperature is too low for normal plant growth, it must be heated to meet the temperature requirements for plant growth. Therefore, this device employs the following methods to increase the condensate water temperature:

[0037] The refrigeration system 4 includes a compressor 4-1, a shaped turbine fan 4-2, an evaporator 4-3, a condenser 4-4, a condensation fin 4-5, and a water collection coil 4-6. The compressor 4-1 is connected to the evaporator 4-3 and the condenser 4-4. The condensation fin 4-5 is disposed on the evaporator 4-3. The water collection coil 4-6 is disposed below the condensation fin 4-5. The drain end of the water collection coil 4-6 is connected to the inlet end of the water storage tank 6. The evaporator 4-3 is located on the air inlet side of the condenser 4-4. The air inlet side of the shaped turbine fan 4-2 is located on the air outlet side of the condenser 4-4. An air inlet 27 is provided on the outer casing of the air inlet side of the evaporator 4-3.

[0038] When the refrigeration system 4 is powered on, the compressor 4-1 starts to work, and the shaped turbine fan 4-2 works at the same time. Air enters the device through the device air inlet 27 and passes through the evaporator 4-3 in the direction of the arrow in the figure. The low-temperature evaporator condenses the water vapor in the air into water droplets. The condensed water droplets drip along the evaporator fins into the water collection coil 4-6 and flow into the water storage tank 6.Figure 2 In the process, air is condensed by evaporator 4-3 and becomes a low-temperature dry gas. Under the action of turbine fan 4-2, the dry and cold air enters the heat dissipation fins of condenser 4-4 in the direction indicated by the arrow in the figure, taking away the heat of the high-temperature refrigerant in the condenser and turning the refrigerant into a liquid state, thus providing conditions for the next round of refrigeration.

[0039] The water storage tank 6 is provided with a water storage tank heating air duct 5. The irregularly shaped turbine fan 4-2 is provided with a first air outlet 4-21 and a second air outlet 4-22. The second air outlet 4-22 is connected to the first air inlet 5-1 and the second air inlet 5-2 of the water storage tank heating air duct 5 through a hot air duct 26. The water storage tank heating air duct 5 is located inside the water storage tank 6. The first air inlet 5-1 and the second air inlet 5-2 are located at the upper end of the water storage tank 6. The first air outlet 5-3 and the second air outlet 5-4 of the water storage tank heating air duct 5 are located on the lower outer side of the water storage tank 6.

[0040] like Figure 3 As shown, the special feature of the irregularly shaped turbine fan 4-2 is that it has two air outlets, 4-21 and 4-22, both located tangentially to the outer edge of the fan. Based on aerodynamic principles and experimental verification, when the irregularly shaped turbine fan rotates at high speed, air enters the irregularly shaped turbine fan 4-2 in the direction indicated by the arrow and, under the action of centrifugal force, is discharged along the two air outlets, the upper outer tangent 4-21 and the lower outer tangent 4-22. After passing through the condenser 4-4's heat dissipation fins, the air temperature rises, and then it enters the irregularly shaped turbine fan 4-2. Following the working principle of the irregularly shaped turbine fan 4-2 described above, refer to... Figure 3 As shown, a portion of the hot air is discharged upwards along the tangent 4-21 of the irregular turbine fan 4-2, while another portion of the hot air is discharged upwards along the lower outer tangent 4-22 in the air guide pipe 26. Figure 5 Guided by ), it enters the upper heating duct 5 of the water storage tank. Figure 4 The two inlets 5-1 and 5-2 pass through the water storage tank 6 and heat the condensate in the water storage tank. Then, the condensate is discharged from the device through the two outlets 5-3 and 5-4 of the water storage tank heating duct 5. Figure 4 When hot air passes through the air inlets 5-1 and 5-2 of the hollow heating duct 5 in the water storage tank, it can heat the condensate in the water storage tank 6 to raise the temperature of the condensate in the water storage tank to a level suitable for plant growth. Figure 5In the middle, the air inlet 26-1 is connected to the lower outer tangent air outlet 4-22 of the turbine fan 4-2, receiving the hot air from the lower outer tangent air outlet 4-22 of the turbine fan 4-2. 26-2 and 26-3 are the two air outlets of the air guide pipe 26. The hot air from the turbine fan 4-2 is guided by the air guide pipe 26 and enters the corresponding air inlets 5-1 and 5-2 of the ventilation pipe on the upper ventilation duct of the water storage tank heating air duct through the two air outlets 26-2 and 26-3 respectively. After passing through the water storage tank 6, the hot air is discharged outside the device through the lower heating air duct outlets 5-3 and 5-4 of the water storage tank 6.

[0041] The temperature control component includes a water level sensor 7, a water temperature sensor 8, a heating wire 9, a water tank contact module 10, and a device end contact module 11. The water level sensor 7 and the water temperature sensor 8 are both located inside the water tank 6. The signal output terminals of the water level sensor 7 and the water temperature sensor 8 are connected to the signal input terminal of the microprocessor component 1. The heating wire 9 is located at the bottom of the water tank 6. The power output terminal of the heating wire 9 is connected to the water tank contact module 10. The power input terminal of the water tank contact module 10 is connected to the power supply 3 through the device end contact module 11. The control signal terminal of the device end contact module 11 is electrically connected to the control signal output terminal of the microprocessor component 1.

[0042] Figure 6 (For ease of drawing and to avoid visual interference, the heating duct 5 of the water tank is omitted in the figure; the left part of the figure is a schematic diagram of the lower part of the main body of the device related to the water tank, and the right part is the water tank and its bottom structure.) When the set watering time is reached, the system issues instructions according to a pre-set program based on the collected temperature data. When the set watering time is reached, the water temperature sensor 8 detects the water temperature in real time. When the water temperature in the water tank provided by the water temperature sensor 8 is lower than the ambient temperature, and the temperature difference exceeds the set threshold (5 degrees Celsius), the microprocessor component 1, according to the pre-set program, instructs the power supply 3 to provide power to the heating wire 9. The heating wire 9 is energized and heats up, heating the water in the water tank. When the water temperature rises and the difference between the water temperature and the ambient temperature is less than the set value (5 degrees Celsius), the microprocessor component 1, according to the pre-set program, instructs the power supply 3 to stop providing power to the heating wire 9, and the heating wire stops working. Furthermore, Figure 6 The heating wire 9 can be integrated into a heating module (i.e., heating tube) and installed at the bottom of the water tank 6 to avoid increasing the difficulty in actual manufacturing. However, for the sake of convenience, the heating wire 9 is used to represent it in the drawings of this instruction manual.

[0043] Through the above structure and working mechanism, the temperature of the condensate in the water storage tank can be increased to meet the optimal water temperature required for plant growth, thus completely solving the biggest obstacle to using condensate to irrigate flowers and plants.

In the diagram, the water storage tank contact module 10 is recessed inside the tank body of the water storage tank 6.

The protruding part of the contact module 11 on the main body of the device corresponds to the position of the water storage tank contact module 10. When the water storage tank 6 is placed in place on the main body of the device, the lower surface of the water storage tank contact module 10 and the upper surface of the contact module 11 on the main body of the device are aligned. When the components are aligned, the water level sensor device end contact 11-1, water temperature sensor device end contact 11-2, and heating wire power cord device end contact 11-3 on the upper surface of the device main body end contact module 11 respectively contact the water level sensor contact 10-1, water temperature sensor contact 10-2, and heating wire power cord contact 10-3 arranged sequentially on the lower surface of the water storage tank contact module 10, thereby making the water level sensor 7, water temperature sensor 8, and heating wire 9 at the bottom of the water storage tank connected to the microprocessor component 1 and power system 3 on the device main body respectively.

The passive check valve 15 is a transverse tubular structure, wherein 15-4 is the outer filter screen of the passive check valve, and after the water passes through the filter screen 15-4, impurities in the water can be filtered out to avoid clogging of the irrigation system.

[0049] Figure 9 As shown in FIG. 6-1, 15-5 is the internal spring of the passive check valve 15, one end of the spring is fixed to the bottom of the passive check valve, and the other end is fixed with a piston sheet 15-6, and 15-7 is the outlet pipe orifice of the passive check valve, the diameter of the outlet pipe orifice 15-7 of the passive check valve is smaller than the diameter of the piston sheet 15-6. Under normal circumstances, the piston sheet 15-6 tightly presses against and completely covers the outlet pipe orifice 15-7 of the passive check valve under the action of the spring 15-5, so as to avoid leakage of the water in the water storage tank, but if Figure 9 As shown in FIG. 6-1, under the action of external force, the piston sheet 15-6 can move backward (right) in the tubular cavity after overcoming the elastic force of the spring 15-5, so that the outlet pipe orifice 15-7 of the passive check valve is forced to open, and the water can flow out.

[0050] Figure 9 As shown in FIG. 6-1, 15-8 is the inner wall rubber layer of the passive check valve outlet pipe, 16-1 is the hollow cylindrical pipe head at the front end of the forced irrigation water pump 16, the front part of the hollow cylindrical pipe head 16-1 has a protruding part 16-3, the diameter of the protruding part 16-3 is slightly larger than the inner diameter of the passive check valve outlet pipe rubber layer 15-8, and the diameter of the remaining part of the hollow cylindrical pipe head 16-1 is slightly smaller than the inner diameter of the passive check valve outlet pipe inner wall rubber layer 15-8. When the hollow cylindrical pipe head 16-1 is inserted into the passive check valve outlet pipe 15-7, the protruding part 16-3 is in close contact with the elastic rubber layer 15-8 of the passive check valve outlet pipe inner wall, thereby avoiding leakage of the water to the outside of the hollow cylindrical pipe head 16-1.

[0051] Since the hollow cylindrical pipe head 16-1 is connected with the forced irrigation water pump 16, and the forced irrigation water pump 16 is fixed on the device main body. Under the above structure, when the water storage tank 6 is removed from the device, the hollow cylindrical pipe head 16-1 will be pulled out of the passive check valve outlet pipe 15-7, at this time the spring 15-5 pushes the piston sheet 15-6 to immediately block the passive check valve outlet pipe orifice 15-7, thereby avoiding leakage of the water.

[0052] When the water storage tank is placed back to the device, the hollow cylindrical pipe head 16-1 is inserted into the passive one-way valve outlet pipe rubber layer 15-8, the hollow cylindrical pipe head 16-1 overcomes the force of the spring 15-5, and the piston sheet 15-6 no longer blocks the one-way valve water outlet. The water in the water storage tank 6 flows into the hollow cylindrical pipe head 16-1 through the front small hole 16-2 of the hollow cylindrical pipe head 16-1, flows through the forced irrigation water pump and the electromagnetic valve, and finally is used for irrigating flowers and plants under the guidance of the irrigation pipeline system. Figure 10 The forced irrigation water pump 16 is a centrifugal pump, which has a large gap between the pump blade and the pump wall. In the case of stopping working, water can flow through the pump core 16-4 in the direction of the arrow 16-1 (i.e. the hollow cylindrical pipe head 16-1 in the figure), and flows out of the pump body along 16-5. Therefore, the forced irrigation water pump 16 does not affect the water flow after stopping working. Figure 9

[0053] When the installation height of the device is higher than the height of the flowerpot, the flowers and plants can be irrigated by the self-flowing mode. In the self-flowing irrigation mode, the forced irrigation water pump 16 stops working. Since the forced irrigation water pump 16 does not affect the water flow after stopping working, the water flow can flow through the forced irrigation water pump 16 and smoothly flow into the flowerpot. In the case that the device is lower than the height of the flowerpot, the “forced irrigation” mode is selected. The forced irrigation water pump 16 starts working with the working of the electromagnetic valve 17, pressurizes the water body in the direction of the arrow, and irrigates the flowers and plants at a high place.

[0054] In the figure, 15 is a passive one-way valve, 16 is a forced irrigation water pump, 17-1 and 17-2 are electromagnetic valves, and 17-11 and 17-21 are water outlet pipes of the electromagnetic valves 17-1 and 17-2, respectively. The forced irrigation water pump 16 is connected with the hollow cylindrical pipe head 16-1, and both are fixed on the device body. The water in the hollow cylindrical pipe head 16-1 can flow into the forced irrigation water pump 16, is pressurized by the forced irrigation water pump 16, and is used for forced irrigation of the flowers and plants with a relative height higher than the device. In the case that the forced irrigation water pump 16 stops working, the water flows through the pump core and self-irrigates the flowers and plants.

[0055] The electromagnetic valves 17-1 and 17-2 are connected to the water outlet pipes of the forced irrigation water pump 16, and are in a parallel state between them. Since the two electromagnetic valves are in a parallel state, when one of the electromagnetic valves 17-1 and 17-2 is in a closed state, it does not affect the normal working of the other. The electromagnetic valves 17-1 and 17-2 are respectively controlled by the power supply system 3. When the power is on, the electromagnetic valves 17-1 and 17-2 are opened, the water flow passes through, and when the power is off, the electromagnetic valves 17-1 and 17-2 are closed, and the water flow is prevented from passing through.

[0056] ​The water distribution pipeline water inlet 18-1 and 18-2 are communicated with the two water outlet pipes 17-11 and 17-21 of the electromagnetic valves 17-1 and 17-2 respectively, and the water from the electromagnetic valves is guided to the adjustable water volume needle water-saving drip emitter 19 at the end of the system.

The drip speed observation hole 19-6 can directly observe the drip irrigation speed of the water flow, and then the water quantity adjusting knob 19-52 is manually adjusted to control the drip irrigation speed. The drip speed of the flowerpot with more soil can be faster, and the drip speed of the flowerpot with less soil can be slower. In this way, different flowerpots can be fully irrigated in the same drip irrigation time, and the situation that the flowerpot with more soil is not sufficiently irrigated and the flowerpot with less soil is excessively irrigated can be avoided. 19-7 is a needle water-saving drip irrigation device 19 end small hole, the water body dripped in is infiltrated to the soil near the roots of flowers and plants through the small hole to provide water for the growth of flowers and plants.

In initial use, the water storage tank 6 is filled with water by hand, the drip irrigation speed of each flowerpot is observed and adjusted through the drip speed observation hole according to the method described in the specification, and uniform irrigation of flowers and plants can be realized.

[0060] In the figure, 19-5 is a cylindrical water amount adjusting rod, the water amount adjusting rod 19-5 is installed in the water amount adjusting rod installation hole 19-34 on the side of the sealing cavity 19-3.

The circular hole 19-53 in the middle of the water amount adjusting rod corresponds to the bottom central circular hole 19-33 of the sealing cavity 19-3 below and corresponds to the middle circular hole 19-43 of the gasket 19-4 above. When the three are completely consistent in direction, the water can flow in full amount, when the adjusting knob 19-52 is twisted to make 19-53 partially correspond to the other two circular holes 19-33 and 19-43, the water flows in a small amount, thereby adjusting the drip irrigation speed.

[0062] Figure 7The structure diagram of the device in the semiconductor refrigeration mode is shown in the figure. The refrigeration system 4 includes a special-shaped turbine fan 4-2, a water collecting pipe 4-6, a semiconductor refrigerator 23, a semiconductor refrigeration fin heat dissipation fin 24, and a cold end dewing fin 25.

In the figure, air enters the device under the action of the special-shaped turbine fan 4-2 along the arrow direction, first passes through the cold end dewing fin 25 to condense water vapor in the air into dew, and then enters the water storage tank 6 through the water collecting pipe 4-6. After passing through the cold end dewing fin 25, the air becomes dry and cold air, and under the action of the special-shaped turbine fan 4-2, the air enters the heat dissipation fin 24 along the arrow direction in the figure to heat the semiconductor refrigeration fin heat dissipation end. After passing through the heat dissipation fin 24, the temperature of the air rises, and under the action of the special-shaped turbine fan 4-2, the air is divided into two parts.

[0063] Figure 16As shown: the microprocessor assembly 1 includes a first microprocessor 1-1, a second microprocessor 1-2, a third microprocessor 1-3, a fourth microprocessor 1-4, a fifth microprocessor 1-5, a sixth microprocessor 1-6, wherein the first microprocessor 1-1 is responsible for the refrigeration system 4 according to the pre-set program instruction, the second microprocessor 1-2 is responsible for calculating the water temperature difference between the water temperature and the ambient temperature, and the calculation result is transmitted to the third microprocessor 1-3, the fourth microprocessor 1-4, the fifth microprocessor 1-5 and the sixth microprocessor 1-6 in real time, the third microprocessor 1-3 is responsible for the work of the heating wire 9 according to the calculation result of the second microprocessor 1-2, the fourth microprocessor 1-4 is responsible for the instruction of the electromagnetic valve group 17 according to the pre-set program under the control of the timer 21 according to the collected water temperature and water level data, and the fourth microprocessor 1-4 is responsible for the instruction of the electromagnetic valve group 17 according to the pre-set program under the control of the timer 21 according to the collected water temperature and water level data. The fifth microprocessor 1-5 is responsible for controlling the opening and closing of the electromagnetic valve group 17 by using the detection result of the soil humidity detector, and the sixth microprocessor 1-6 is responsible for the opening and closing of the external water source electromagnetic valve 29 in the external water source mode. The first microprocessor 1-1 also instructs the prompt lamp 20 to display according to the water level signal, the prompt lamp 20 includes a full water indication lamp 20-1 and a water shortage and manual water adding prompt lamp 20-2, and the timer 22 records the watering time. When the watering time reaches, the corresponding unit of the fourth microprocessor 1-4 instructs the power supply 3 to close the corresponding electromagnetic valve to stop watering.

[0064] The water storage tank 6 is also provided with a water storage tank manual water adding and soluble fertilizer adding port 13, a micro air pump 28, an external water source control mode switch 30, a bubble generator 31, an air pipe 32 and an external water source connector 33. The water storage tank manual water adding and soluble fertilizer adding port 13 is arranged at the upper end of the water storage tank 6. The external water source connector 33 is connected with the water storage tank manual water adding and soluble fertilizer adding port 13 through the external water source electromagnetic valve 29. The micro air pump 28 is connected with the bubble generator 31 through the air pipe 32. The bubble generator 31 is located at the bottom of the water storage tank 6. The external water source electromagnetic valve 29 is connected with the control signal output end of the microprocessor assembly 1 through the external water source control mode switch 30. The upper end of the household automatic flower watering device shell body is provided with a top mounting connector 14. The top mounting connector 14 can install the device on the ceiling top to meet the needs in special cases when it cannot be installed on the wall.

[0065] The first microprocessor 1-1 is used to instruct the refrigeration system 4 to work in time. The specific logical relationship is that when the water storage tank 6 is installed in place, the contact module 10 on the side of the water storage tank 6 is communicated with the device end contact module 11, the total power supply is turned on, and the device start total switch is pressed. Various sensors in the device start to detect and real-time data transmission to the microprocessor assembly 1. When the water level sensor 7 detects that the water level of the water storage tank is not full, the environmental temperature and humidity sensor 2 detects that the environmental temperature is higher than the set temperature (usually more than 5 degrees Celsius), the air humidity data is higher than the set value (usually more than 30%), and the three data conditions are met at the same time, the central microprocessor first microprocessor 1-1 according to the pre-set program, sends instructions to the power supply system 3, and the power supply system 3 provides power to the refrigeration system 4, and the refrigeration system 4 starts to work and provides condensed water to the water storage tank.

[0066] When the refrigeration system 4 works for a period of time, the water level of the water storage tank 6 gradually rises, and the water level sensor 7 installed at the bottom of the water storage tank 6 real-time water level data to the central microprocessor first microprocessor 1-1, when the water level sensor 7 transmits the water level value to the central microprocessor first microprocessor 1-1 reaches the pre-set water full data, according to the pre-set program, the central microprocessor first microprocessor 1-1 sends working instruction to the power supply system 3, all three conditions cannot be met at the same time, the central microprocessor first microprocessor 1-1 no longer sends power-on instruction to the power supply system 3, the power supply system stops power supply to the refrigeration system, and the refrigeration system stops dewing.

[0067] When the water level sensor 7 senses the water level value reaches the pre-set water full data, the central microprocessor first microprocessor 1-1 sends instructions to the power supply system 3 at the same time, and the power supply system 3 provides power to the water full indicator lamp 20-1, and the water full indicator lamp 20-1 is lighted, prompting that the water storage tank is in the water full state.

[0068] The second microprocessor 1-2 is responsible for real-time calculation of the difference between water temperature and environmental temperature, and real-time transmission to the related processor. The environmental temperature sensor 2 sensing data and water temperature sensor 8 sensing data are provided to the central microprocessor second microprocessor 1-2 at the same time, and the central microprocessor second microprocessor 1-2 subtracts the water temperature sensor 8 sensing data from the collected environmental temperature sensor 2 sensing data, and obtains a data value. This value represents the difference between the water temperature and the environmental temperature. When the value is less than 5, it indicates that the water temperature difference with the environmental temperature is less than 5 degrees Celsius, and the water temperature is suitable for watering flowers; when the data value is greater than 5, it indicates that the water temperature of the water storage tank is lower than the environmental temperature, and the temperature difference exceeds 5 degrees Celsius, and the water temperature is too low to be suitable for watering flowers. The central microprocessor second microprocessor 1-2 real-time transmits the temperature difference data to the related processor including the central microprocessor third microprocessor 1-3.

[0069] The third microprocessor 1-3 is responsible for instructing the power supply system to supply or cut off power to the heating wire 9 in time, and moderately increasing the water temperature in the water storage tank. When the refrigeration system of the device starts to produce dew, under the action of the special-shaped turbine fan 4-2, hot air enters the water storage tank heating duct 5 through the air guide pipe 26 to heat the condensate water in the water storage tank 6, so that the temperature of the condensate water is greatly increased, but the water temperature in the water storage tank may still not reach the optimal temperature required for watering flowers. At this time, the third microprocessor 1-3 is responsible for instructing the heating wire (tube) 9 to work in time. When the water level sensor 7 senses data indicating that the water storage tank is in a full state, the watering time set by the timer 21 has also arrived, and the temperature difference between the water temperature and the environment is greater than 5 degrees Celsius, the three conditions are met at the same time, the third microprocessor 1-3 immediately instructs the power supply system 3 to provide power to the heating wire (tube) 9 according to the pre-set program, the heating wire generates heat and gradually increases the water temperature in the tank. The water temperature sensor 8 dynamically transmits the temperature difference data to the second microprocessor 1-2 in real time. When the temperature difference data transmitted by the second microprocessor 1-2 in real time is less than 5, it indicates that the water temperature has met the conditions for watering flowers, and the conditions for continuing to supply power to the heating wire 9 are no longer met at the same time. The second microprocessor 1-2 transmits the temperature difference data to the third microprocessor 1-3 in real time. When the third microprocessor 1-3 receives data from the second microprocessor 1-2 less than 5 degrees Celsius, it indicates that the temperature difference between the water temperature and the environment is less than 5 degrees Celsius. The third microprocessor 1-3 stops the power supply system 3 from providing power to the heating wire 9 according to the pre-set program.

[0070] The fourth microprocessor 1-4 is responsible for instructing the electromagnetic valve 17 to open and close according to the pre-set program, so as to water flowers in time. Figure 16 When the watering time data set by the timer 21 has arrived, the water temperature data sent by the second microprocessor 1-2 to the fourth microprocessor 1-4 also meets the watering conditions, and the water level value sent by the water level sensor 7 to the fourth microprocessor 1-4 reaches the pre-set water level data, the above three conditions are met at the same time, the fourth microprocessor 1-4 receives the above data, and according to the pre-set program, the power supply system 3 provides power to the electromagnetic valve 17, and at the same time, the timer 22 starts to count the watering time. The electromagnetic valve 17 opens the water source for watering flowers at the same time, and the water in the water storage tank 6 is watered through the electromagnetic valve 17 and the water distribution pipeline. At the same time, the timer 22 starts to count, and when the watering time set by the timer 22 arrives, it indicates that the flowers have been fully and thoroughly watered, and the timer 22 sends a signal to the fourth microprocessor 1-4, and the fourth microprocessor 1-4 instructs the power supply system 3 to stop providing power to the electromagnetic valve 17. The electromagnetic valve 17 is immediately closed and stops providing water to the flowers.

[0071] When the electromagnetic valve 17 is closed and the power supply stops working, the central microprocessor first microprocessor 1-1 restarts to determine whether to start the refrigeration system 4 to refrigerate and take water according to the data provided by the water level sensor 7 and the ambient temperature sensor 2 according to the pre-set program, and the process is repeated.

[0072] Some residents have a variety of flowers, both herbs and woody plants, and the number is large. The irrigation cycle of different varieties of flowers and plants is quite different. The electromagnetic valve of the device can be divided into two groups, i.e. electromagnetic valves 17-1 and 17-2 (it can also be increased to more than two, and this specification takes two as an example. The control principle of more than two electromagnetic valves is the same as that of two). They correspond to different irrigation cycles of flowers and plants, respectively. Electromagnetic valves 17-1 and 17-2 correspond to instructions from different units in the fourth microprocessor 1-4, i.e. the fourth microprocessor 1-4-1 and the fourth microprocessor 1-4-2, respectively, and are controlled by timers 21-1 and 21-2, respectively. The length of time that the electromagnetic valve is open to water the flowers is recorded by the timer 22. When the watering time reaches, it indicates that the flowers have been thoroughly irrigated. To save water and avoid over-irrigation of flowers, when the watering time recorded by the timer 22 reaches, the corresponding unit of the fourth microprocessor 1-4 instructs the power supply system 3 to close the corresponding electromagnetic valve to stop further irrigation.

[0073] Special case one, when the height of the flowerpot is higher than the height of the device, and the water body cannot be self-flowing to water the flowers, the user presses the "forced irrigation mode" button on the device to start the forced irrigation mode. After pressing the forced irrigation mode button, Figure 16 The power supply switch 16-6 is closed, the forced irrigation water pump 16 and the electromagnetic valve 17 are connected in parallel in the same circuit, and the forced irrigation water pump 16 works with the electromagnetic valve 17 power on and stops working with the electromagnetic valve 17 power off. When the forced irrigation mode is cancelled, the power supply switch 16-6 is opened, and the forced irrigation water pump 16 is disconnected from the parallel circuit of the electromagnetic valve 17 power supply. When the user presses the "forced irrigation mode" button 16-6 on the device, the forced irrigation water pump 16 and the electromagnetic valve 17 can be connected in parallel in the same circuit. Its working principle belongs to the method of simple circuit connection and disconnection, that is, the ordinary power switch. This specification will not be described again.

[0074] When the user selects to start the forced irrigation mode, the central microprocessor CPU I-4 instructs the power supply system 3 to supply power to the electromagnetic valve 17 at the same time, and the forced irrigation pump 16 gets power and starts at the same time with the electromagnetic valve 17. Conversely, when the central microprocessor fourth microprocessor 1-4 instructs the power supply system 3 to stop supplying power to the electromagnetic valve 17, the power supply system 3 stops supplying power to the forced irrigation pump 16.

[0075] Special case two, when using an external soil humidity detector mode and controlling the watering rule according to the data detected by the soil humidity detector,Figure 16 As shown in the switching module B, when the plug is inserted, under the action of the plug, the fourth microprocessor 1-4 is disconnected with the communication line of the power system 3, the fifth microprocessor 1-5 is connected with the line of the power system 3, the switch of the electromagnetic valve 17 is controlled by the fifth microprocessor 1-5, and the fourth microprocessor 1-4 no longer controls the switch of the electromagnetic valve 17. The fifth microprocessor 1-5 receives the soil humidity data from the soil humidity detector 12-1, receives the water level sensor and water temperature sensor data, and receives the time length control of the timer 22. When the water temperature and water level data collected by the central microprocessor fifth microprocessor 1-5 meet the conditions, and the soil humidity data detected by the soil humidity detector 12 is less than the set value, it indicates that the flowerpot soil is dry and needs to be irrigated. When the above three data conditions are met, the central microprocessor fifth microprocessor 1-5 provides power to the timer 22 and the electromagnetic valve 17 according to the pre-set program instruction, the timer 22 starts timing, the electromagnetic valve 17 is opened at the same time, and the water in the water tank 6 is irrigated to the flowers and plants through the electromagnetic valve and the water distribution pipeline. At the same time, the timer 22 starts timing, and when the set irrigation time of the timer 22 reaches, it indicates that the flowers and plants have been fully irrigated, and the timer 22 sends a signal to the central microprocessor fifth microprocessor 1-5, and the central microprocessor fifth microprocessor 1-5 instructs the power system 3 to stop providing power to the electromagnetic valve 17, and the electromagnetic valve 17 is immediately closed and stops providing water to the flowers and plants.

[0076] In a special case three, due to different types of flowers and plants, the irrigation cycle requirements are different, some flowers and plants need frequent irrigation, and some flowers and plants have a long irrigation interval. Therefore, the device is provided with two electromagnetic valves, namely electromagnetic valve 17-1 and electromagnetic valve 17-2, which are connected in parallel with the water outlet of the forced irrigation water pump 16. The irrigation cycle of the electromagnetic valve 17-1 and 17-2 is controlled by the timer 21-1 and 21-2 respectively, and is set by the user on the panel respectively. The user inserts the drip irrigation plug corresponding to the electromagnetic valve with short irrigation cycle into the flowerpot with short irrigation cycle, and inserts the drip irrigation plug corresponding to the electromagnetic valve with long irrigation cycle into the flowerpot with long irrigation cycle, so as to realize irrigation according to the required cycle.

[0077] The present application has the function of external water source to solve the water source. Generally, only in extremely cold weather conditions, the dew system cannot generate dew, and at this time the plants are in a dormant state, the water consumption is very small, and usually no irrigation is needed, but individual flower growers have greenhouse flower sheds, and still need to irrigate the flowers and plants in extremely cold weather conditions. In order to meet the needs of individual flower growers, an external water source interface can be reserved on the device and matched with the corresponding function. In the case of external water source, the user should first press the switching button in the external water source switching module A to switch the water source mode to the external water source mode.

[0078] When the switching button 30 is pressed in the switching module A, under the action of the top head, the fourth microprocessor 1-4 and the fifth microprocessor 1-5 are disconnected from the power supply system, and no longer control the opening and closing of the electromagnetic valve 17, at the same time, the sixth microprocessor 1-6 is connected to the power supply system, and the opening and closing of the electromagnetic valve 17 and the micro air pump 28 are controlled by the sixth microprocessor 1-6. In the external water source mode, when the water level sensor 7 senses that the water level does not reach the set water level, the sixth microprocessor 1-6 instructs the electromagnetic valve 29 to open, and the external water source enters the water storage tank until the water storage tank is full, at which time the sixth microprocessor 1-6 instructs the electromagnetic valve 29 to close, and the external water source stops supplying water to the water storage tank.

[0079] When the watering time comes, the sixth microprocessor 1-6 receives the information of the timer 21, instructs the power supply system to supply power to the micro air pump 28 to work, and the air bubble generator 31 at the bottom of the water storage tank communicates with the micro air pump 28 to continuously generate air bubbles to carry away the fluorine chloride compounds in the water until the set air bubble generator working time reaches, the micro air pump stops working, and then the sixth microprocessor 1-6 instructs the electromagnetic valve 17 to open to water the flowers and plants.

[0080] Special case four: when the environmental temperature and humidity sensor 2 senses that the outdoor temperature and humidity is lower than the set temperature, indicating that the environmental temperature is too low, the dew sheet cannot produce dew, and the water level of the water storage tank 6 is lower than the set water level, the central microprocessor CPU 1 instructs the power supply system 3 to supply power to the LED water shortage prompt lamp 20-2 according to the pre-set program, prompting the user to manually add water through the manual water inlet 13 of the water storage tank 6 to avoid water shortage and unable to water the flowers and plants. When the water storage tank 6 is full or the temperature rises, the above conditions are no longer met, the central microprocessor CPU 1 instructs the power supply system 3 to stop providing power to the LED water shortage prompt lamp 20-2 according to the pre-set program, and the LED water shortage prompt lamp 20-2 is extinguished.

[0081] Special case five: when the semiconductor refrigeration system is used to produce dew, in actual use, the semiconductor refrigerator 23, the heat dissipation fin 24 and the cold end dew fin 25 linked with the power supply are first subjected to the action of the special-shaped turbine fan 4-2, and the air is subjected to dew and cooling by the cold end dew fin 25, and then the heat is taken away by the heat dissipation fin 24, and the dew water is collected in the water collecting pipe 4-6 and flows into the water storage tank 6.

[0082] Further, the soluble plant growth fertilizer effervescent tablets, particles and other additives can be added through the manual water inlet 13.

[0083] The technical scheme of the present application is not limited to the above specific embodiments, and any technical modification made according to the technical scheme of the present application falls within the protection scope of the present application.
