Description

Technical Field

[0001] The utility model relates to the technical field of medicine spraying devices, in particular to a water delivery pipe with adjustable length. Background Art

[0002] In the garden, regular pruning, fertilization and insecticide spraying are required. The insecticide spray is used to kill small insects that are harmful to garden plants. Workers need to use a spray device to kill insects. The trees in the garden are of different heights. For short shrubs, a spray device can be used to directly spray the liquid for insecticide, but it is more difficult to spray insects on taller trees.

[0003] In order to spray the medicine liquid farther, an air pump can be connected to the side wall of the spraying pipe. When spraying, the air pump introduces fast-flowing gas into the pipe, and then the gas is sprayed out of the pipe with the medicine liquid. In this way, the medicine liquid can be sprayed farther. When the gas is sprayed out of the pipe, the gas flow speed will decrease rapidly. Therefore, using this method can only increase the spraying distance of the medicine liquid to a certain extent.

[0004] Therefore, we propose a water pipe with adjustable length to solve the above problems. Utility Model Content
