Description

Technical Field

[0001] The invention belongs to the technical field of planting boxes, and in particular relates to a mobile hanging planting facility for a building. Background Art

[0002] With the development of economy and the advancement of science and technology, more and more people are moving to cities to live. As the area of ​​urban housing is small, it is very inconvenient for some people who want to raise various animals and plants. People usually place planting boxes indoors to raise some animals and plants, but placing planting boxes indoors still occupies living area and affects people's lives.

[0003] Animals also produce a lot of feces every day, which not only affects the indoor odor, but also requires people to spend a lot of time cleaning the feces every day. At the same time, plants also need to absorb sufficient sunlight every day. Placing plants indoors is not conducive to photosynthesis and hinders plant growth. Plant growth also requires some fertilizers. Most of the existing fertilizers will affect the soil quality. Long-term fertilization will damage the soil and is not conducive to the sustainable growth of plants.

[0004] If the planting box is hung on the wall and placed outdoors, it will not be conducive to people feeding the animals every day. In addition, there are many insects outdoors that will bite animals and plants, which is not conducive to their growth and may even cause their death. Summary of the invention
