DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 1 and FIG. 2. It can be clearly seen from the figures that an aeroponic system with uninterrupted operation and energy saving of the invention comprises the following.

A first nutrient solution storage tank 1, a nutrient solution inlet 11 is disposed on the first nutrient solution storage tank 1, the nutrient solution inlet 11 is connected with a recovery pipeline 111, the first nutrient solution storage tank 1 is provided with a feeding pipeline 113, the feeding pipeline 113 is provided with a feeding valve 14 thereon; a second nutrient solution storage tank 2 connected to the feeding pipeline 113, an air inlet valve 21 and a liquid outlet pipeline 22 are provided on the second nutrient solution storage tank 2, a control valve 221 is disposed on the liquid outlet pipeline 22; a gas storage tank 3 connected to the air inlet valve 21 of the second nutrient solution storage tank 2; an air compressor 4 connected to the gas storage tanks 3; and a planting module 5 connected to the recovery pipeline 111 of the first nutrient solution storage tank 1 and the liquid outlet pipeline 22 of the second nutrient solution storage tank 2, wherein the second nutrient solution storage tank 2 can be a pressure container, such as a high-pressure tank, etc., which stores a high-pressure gas G and a nutrient solution L, the control valve 221 can be a general mechanical valve or an electronic valve. When the planting module 5 needs the nutrient solution L, the control valve 221 is opened, the high-pressure gas G in the second nutrient solution storage tank 2 pushes the nutrient solution L through the liquid outlet pipeline 22 to the planting module 5. Therefore, the invention relies on gas pressure to deliver the nutrient solution L and is different from the prior art which mainly drives a motor or a pump by electricity, and the invention is capable of saving energy. In addition, after the nutrient solution L is used, the excess nutrient solution L of the planting module 5 can be recovered to the first nutrient solution storage tank 1 through the recovery pipeline 111, so that the nutrient solution L can be recycled and reused to reduce a waste of the nutrient solution L.

In addition, the gas storage tank 3 can be a pressure container for storing the high-pressure gas G compressed by the air compressor 4. When air pressure in the second nutrient solution storage tank 2 is insufficient, the nutrient solution L cannot be pushed to the planting module 5, at this time, the high-pressure gas G of the gas storage tank 3 can be supplemented to the second nutrient solution storage tank 2 by opening the air inlet valve 21, so that the high-pressure gas G in the second nutrient solution storage tank 2 can maintain a high-pressure state. In a state of provided with power supply, the air compressor 4 can be used to store a large amount of the high-pressure gas G in the gas storage tank 3. When power is turned off, the high-pressure gas G stored in the gas storage tank 3 in advance can be used to maintain operation of the system in order to keep supplying the nutrient solution L uninterruptedly and to avoid slow growth or death of plants.

Please refer to FIG. 1, FIG. 2 and FIG. 3. A filter 112 is further provided at the nutrient solution inlet 11 of the first nutrient solution storage tank 1, and a liquid level detector 12 and an acid-base sensor 13 are further disposed on the first nutrient solution storage tank 1. A disposing position of the first nutrient solution storage tank 1 is higher than a disposing position of the second nutrient solution storage tank 2. A pressure relief valve 23 is further provided on the second nutrient solution storage tank 2. When the gas storage tank 3 and the air inlet valve 21 of the second nutrient solution storage tank 2 are connected to each other, an air pressure detector 31 is further provided, wherein the nutrient solution L can be added or the nutrient solution L can be recovered to the first nutrient solution storage tank 1 through the nutrient solution inlet 11 of the first nutrient solution storage tank 1, when the nutrient solution L of the second nutrient solution storage tank 2 decreases, the pressure relief valve 23 on the second nutrient solution storage tank 2 can be opened to release a pressure in the second nutrient solution storage tank 2, and then the feeding valve 14 is opened, at this moment, the nutrient solution L will be replenished from the first nutrient solution storage tank 1 to the second nutrient solution storage tank 2 through the feeding pipeline 113 to complete replenishment of the nutrient solution L. Further, with a disposing position of the first nutrient solution storage tank 1 being higher than a disposing position of the second nutrient solution storage tank 2, the nutrient solution L can be transported to the second nutrient solution storage tank 2 by a pressure difference generated by a difference in height, and therefore other power-consuming equipment such as motors and pumps are not required to assist transportation to achieve an efficacy saving energy. In addition, the air pressure detector 31 installed between the gas storage tank 3 and the air inlet valve 21 of the second nutrient solution storage tank 2 is mainly used to detect an air pressure in the second nutrient solution storage tank 2, if the air pressure is insufficient, the air compressor 4 is activated to drive air into the high-pressure gas G in the gas storage tank 3.

In addition, the liquid level detector 12 and the acid-base sensor 13 are further disposed on the first nutrient solution storage tank 1. The acid-base sensor 13 is used to monitor a pH value of the nutrient solution L, thereby adjusting an acid-base concentration of the nutrient solution L timely to ensure that the nutrient solution L is not deteriorated. The liquid level detector 12 is used to detect a stored amount of the nutrient solution L in the first nutrient solution storage tank 1. When a stored amount of the nutrient solution L is insufficient, the nutrient solution L is added to ensure that the first nutrient solution storage tank 1 has enough nutrient solution L to supply to the second nutrient solution storage tank 2, and a stored amount of the nutrient solution L in the second nutrient solution storage tank 2 can be roughly known by an amount of the nutrient solution L stored in the first nutrient solution storage tank 1. Finally, when the newly added nutrient solution L or the recovered nutrient solution L enters the first nutrient solution storage tank 1, impurities in the nutrient solution L can be filtered through the filter 112 to maintain a quality of the nutrient solution L.

After spraying by the sprinkler 53, the excess or dripped nutrient solution L will fall to the receiving body 52 disposed below the rack body 51, and the nutrient solution L is recovered to the first nutrient solution storage tank 1 through the recovery pipeline 111 connected with the receiving body 52, thereby effectively reducing a waste of the nutrient solution L.

Please refer to FIG. 4, FIG. 5 and FIG. 6, the receiving body 52 is made of waterproof and flexible material, such as waterproof canvas, etc., and the receiving body 52 can be inclined so that a height of one end of the receiving body 52 close to the liquid outlet pipeline 22 is lower than a height of another end of the receiving body 52 away from the liquid outlet pipeline 22, thereby it is more conducive for the nutrient solution L to flow toward the recovery pipeline 111 for recovery. Furthermore, the at least one through hole 541 is respectively provided on the planting pots 54 of the planting module 5, which is mainly used to enable a plant to be inserted into the through hole 54 after being placed on a sponge, so that roots of the plant are located under the planting pot 54, and the nutrient solution L sprayed by the sprinkler 53 can be sprayed to reach the roots of the plants. A spraying angle of the sprinkler 53 can also be adjusted according to growth conditions of the plant roots to make spraying more precise.

In addition, the at least one shielding body 521 is further disposed on sides of the rack body 51, in addition to being mainly used to block the sprinkler 53 from spraying the nutrient solution L outside of the rack body 51 to avoid waste, the shielding body 521 can also be used to shield light from irradiating the roots of the plants. The receiving body 52 and the shielding body 521 are designed to be assembled on and disassembled from the rack body 51. For example, at least one quick-release component 511 can be provided on the rack body 51, at least one lower corresponding component 523 and at least one upper corresponding component 522 can be provided on the receiving body 52 and the shielding body 521 respectively, the quick-release component 511, the upper corresponding component 522 and the lower corresponding component 523 can be components that are easy to disassemble such as double-sided tape, Velcro, hook and hanging hole, etc., thereby the receiving body 52 and the shielding body 521 can be easily removed in order to clean, repair or replace the liquid outlet pipeline 22, the rack body 51, the sprinkler 53, the receiving body 52, and the shielding body 521.

Wherein the rack body 51 is further provided with at least one carbon dioxide supplier 55, at least one lighting device 56, at least one air intake and exhaust device 57, and at least one temperature and humidity sensor 58, wherein the carbon dioxide supplier 55 and the lighting device 56 supply carbon dioxide and light required by the plants, the temperature and humidity sensor 58 senses a current ambient temperature, and the air intake and exhaust device 57 can be a fan or an air conditioner to control air flow and to adjust temperature.

In addition, as shown in FIG. 7, which is a further embodied mode of the invention, since the air compressor 4 does not need to maintain operation of continuously supplying air pressure, the single air compressor 4 can be used to provide the high-pressure gas G required by the gas storage tanks 3.

In summary, compared with the prior art using related equipment for automatically performing watering and fertilization which causes various drawbacks and problems that cannot be solved, through the special design of the first nutrient solution storage tank 1, the second nutrient solution storage tank 2, the gas storage tank 3, the air compressor 4 and the planting module 5 in the invention, the air compressor 4 is required to operate only when an air pressure of the gas storage tank 3 is insufficient, which greatly reduces the cost of power consumption. Furthermore, with the high-pressure gas G being stored in the gas storage tank 3, the aeroponic system with uninterrupted operation and energy saving of the invention is capable of operating without interruption. Finally, through the recovery and circulation mechanism of the sprayed nutrient solution L provided by the first nutrient solution storage tank 1 and the second nutrient solution storage tank 2 for the planting module 5, waste of the nutrient solution L can be effectively reduced.
