[0002] In modern gardening technology, it has become a common phenomenon to infuse trees. When trees are infested with insect pests, some anti-disease and insecticide liquid or nutrient solution needs to be infused to save the trees. Existing infusion devices often require a series of liquid bottles and PVC pipes, switches, plugs, and needles to cooperate with each other as a set for infusion. However, the existing infusion devices are relatively complicated when infusing and spraying trees, and the infusion devices are troublesome to carry and assemble. At the same time, the infusion devices often have gas and liquid loss in the liquid bottles due to inadequate sealing, and the existing PVC pipes are unusable due to temperature changes, resulting in the infusion and spraying of medicines being unable to proceed normally. The PVC pipes often need to be replaced to continue, which is costly and has low infusion efficiency. Summary of the invention
