Description

Technical Field

[0001] This utility model belongs to the field of indoor planting technology, specifically relating to an indoor planting device based on aeroponic technology. Background Technology

[0002] In the 1950s, the United States began using hydroponics in greenhouses to produce vegetables, becoming the first country to commercialize hydroponics. Before the 1990s, research on hydroponics technology in China mainly focused on importing, absorbing, and assimilating existing technologies. After the 1990s, China began to independently develop hydroponics technologies suitable for its environmental resources. Currently, hydroponics technology in China is widely used in vegetables, flowers, fruit trees, and medicinal herbs. However, many problems remain to be solved in substrate cultivation and hydroponics, such as scientific irrigation and low dissolved oxygen content in the water.

[0003] For example, current traditional soil cultivation techniques use large containers, resulting in significant space waste. Furthermore, the soil is prone to microbial growth, posing hygiene risks. Daily manual watering and fertilization are also required, which is time-consuming. Regular testing of the nutrient solution is also necessary, leading to high maintenance costs.

[0004] The problems mentioned above are less common in aeroponics. The concept of aeroponics was proposed in 1968. This technology uses a spraying device to spray a mist of nutrient solution onto the roots of crops, solving problems such as the adsorption of mineral nutrients by the substrate, the accumulation of nitrite in the nutrient solution, and root hypoxia. It is considered to be the cultivation method with the best water, fertilizer, and air coordination among soilless cultivation techniques.

[0005] However, the static structure of existing aeroponic devices leads to uneven light exposure for plants, affecting photosynthetic efficiency, and the lack of modular design means that planting units cannot be flexibly added or removed. Summary of the Invention

[0006] To address the aforementioned problems in existing technologies, this utility model provides an indoor planting device based on aeroponic technology. This solves the problem that existing soilless cultivation technologies cannot balance space utilization, intelligent control, and ease of maintenance, making it difficult to meet the needs of modern urban families for efficient, clean, and easy-to-operate home planting.

[0007] The purpose of this utility model can be achieved through the following technical solution: an indoor planting device based on aeroponic technology, including a base, a transfer wheel cylinder and a feeding module. The transfer wheel cylinder is rotatably connected to the top surface of the base. The transfer wheel cylinder has a hollow cylindrical structure. The feeding module is installed inside the transfer wheel cylinder. The inner side wall of the transfer wheel cylinder is provided with several cultivation areas. The transfer wheel cylinder continuously rotates on the top surface of the base.

[0008] As a preferred technical solution of this utility model, the inner side wall of the transfer wheel cylinder is provided with several slots, and a breeding template is quickly installed in the slots.

[0009] As a preferred technical solution of this utility model, the feeding module includes a hollow mounting column, a lighting module and a nutrient module. The mounting column is a polygonal column and corresponds one-to-one with the number of breeding areas. The lighting module is installed on each outer side of the mounting column, and the nutrient module is installed between two adjacent lighting modules. The lighting module and the nutrient module are used to control the light intensity and nutrient supply in the breeding area.

[0010] As a preferred technical solution of this utility model, the aeroponic module includes a photosensitive sensor, a light-emitting lamp group, and a main control module. The photosensitive sensor and the light-emitting lamp group are both communicatively connected to the main control module. The photosensitive sensor detects the spectral changes in the aquaculture area in real time, and the main control module dynamically adjusts the output power of the light-emitting lamp group according to the detection results of the photosensitive sensor and the preset program.

[0011] As a preferred embodiment of this utility model, the nutrient module is composed of an ultrasonic atomizer, which sprays nutrients into the breeding area.

[0012] In a preferred embodiment of this invention, the transfer wheel is driven to rotate by a stepper motor and a gearbox.

[0013] The beneficial effects of this invention are as follows: the uniform rotation of the transfer wheel, in conjunction with the aeroponic module, ensures that the plants in each cultivation area receive equal amounts of light and nutrients. This guarantees uniform plant growth and prevents significant differences in light intensity among different plant areas, thus ensuring the photosynthetic efficiency of each plant area. Furthermore, the transfer wheel cultivation method avoids the problem of large planting container area and wasted space. This solves the problem that existing soilless cultivation technologies cannot balance space utilization, intelligent control, and ease of maintenance, making it difficult to meet the needs of modern urban families for efficient, clean, and easy-to-operate home gardening.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Please see Figure 1-2 This embodiment provides an indoor planting device based on aeroponic technology, including a base 1, a transfer wheel cylinder 2, and a feeding module. The transfer wheel cylinder 2 is installed on the top surface of the base 1. The transfer wheel cylinder 2 has a hollow cylindrical structure, and several cultivation zones 3 are provided on the inner side wall of the cylinder. The feeding module is installed inside the transfer wheel cylinder 2 and located on the central axis. During the cultivation process, the plants to be planted are planted in the cultivation zones. At the same time, the feeding module provides the plants with the necessary nutrients. Since the feeding module uses aeroponic technology for supplementation, no additional hydroponic or soil-based materials are needed in the cultivation zones 3 to provide nutrients. To ensure uniform plant growth in each cultivation zone 3 and prevent uneven nutrient distribution, the transfer wheel 2 rotates at a constant speed during cultivation. This, in conjunction with the aeroponic module, ensures that the plants in each cultivation zone 3 receive equal amounts of light and nutrients. This guarantees uniform plant growth and prevents significant differences in light intensity between plant zones, thus ensuring photosynthetic efficiency in each zone. Furthermore, the transfer wheel 2 cultivation method avoids the problem of large planting containers and wasted space, thereby solving the issues of low space utilization, uneven light distribution, and uneven nutrient supply in traditional cultivation techniques.

[0021] To better improve planting space while accommodating more plants of different sizes, in this embodiment, several slots 5 are provided on the inner side wall of the transfer wheel cylinder 2. At the same time, a cultivation template is quickly installed in the slot 5. Different sizes of cultivation templates are assembled by quick-release buckle connection, thereby achieving a dense structure to reduce gaps. Only the necessary support frame and rotation transmission structure are retained to save space. Plants of different specifications can be planted by assembling the cultivation templates, thereby optimizing the three-dimensional planting space and improving the space utilization efficiency.

[0022] To ensure consistent light intensity and stable growth for plants in each cultivation area 3 during the cultivation process, in one embodiment, the feeding module includes a hollow mounting column 4, a light module 6, and a nutrient module 7. The mounting column 4 is a polygonal column corresponding to the number of cultivation areas 3. The light modules 6 are installed on the outer surfaces of the mounting columns 4. The light modules 6 and nutrient modules 7 are used to control the light intensity and nutrient supply in the cultivation areas 3. By aligning the shape of the mounting column 4 with the preset cultivation areas 3, it is ensured that the cultivation areas 3 are evenly illuminated by the light modules 6, thus preventing uneven light distribution and ensuring good plant growth. Meanwhile, the nutrient modules 7 are installed between adjacent light modules 6. The continuously rotating transfer wheel 2 ensures that the nutrients sprayed by the nutrient modules 7 are evenly absorbed by the plants in each cultivation area 3, thereby maximizing space utilization while ensuring more uniform light and nutrient distribution to the plants.

[0023] Because plants require different light intensities at different stages of growth—more precisely, plants need specific light intensities for photosynthesis—plants primarily absorb red and blue light (chlorophyll absorption peaks) for photosynthesis. Other wavelengths (such as green light) are absorbed less or reflected (which is why leaves appear green). Furthermore, different growth stages (such as germination, leaf growth, flowering, and fruiting) have different requirements for the red / blue light ratio, far-red light, and even ultraviolet light. In other words, the type of light received needs to be controlled at different growth stages. Therefore, to better adapt to the needs of different plant growth stages, in one embodiment, the lighting module includes a photosensor, a light-emitting lamp assembly, and a main controller. The module, photosensitive sensor, and light-emitting lamp assembly are all connected to the main control module. The photosensitive sensor detects the spectral changes within the cultivation area 3 in real time. Based on the type of plant being cultivated, the main control module presets the different light requirements for each stage of plant growth. Then, the main control module dynamically adjusts the output power of the light-emitting lamp assembly according to the detection results of the photosensitive sensor and the preset program. The light-emitting lamp assembly consists of at least 3 sets of LED chips. Previously, each set of LED chips had different colored LEDs to meet the needs of plant growth. The main control module precisely adjusts the light-emitting lamp assembly to emit light of specific wavelengths and intensities, so that its spectral composition meets the optimal needs of the plant at the current growth stage.

[0024] To better provide nutrients to the plants in the cultivation area 3, in one embodiment, the nutrient module 7 is composed of an ultrasonic atomizer. The ultrasonic atomizer sprays nutrients into the cultivation area 3. By using the ultrasonic atomizer (frequency 1.7MHz), the nutrient solution is atomized into adjustable droplets of 10-50μm. The droplets are then vertically delivered to the planting unit by a pneumatic pump, causing the nutrients to float to the surface. This, combined with the rotating structure, provides nutrients to the plants by covering the root system with highly permeable aerosol, thus ensuring the plants' growth needs.

[0025] In order to ensure that the rotating drum can rotate at a uniform speed to ensure that each breeding area 3 receives light and nutrients more evenly, in one embodiment, the rotating drum 2 is driven to rotate by a stepper motor and a gearbox. The stepper motor receives a high-frequency pulse signal from the main control module. Each pulse triggers the motor rotor to rotate by a fixed angle. The gearbox then increases the motor torque to avoid insufficient starting torque, thereby ensuring that each breeding unit receives equal light and nutrient distribution.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
