Spraying device for garden

Abstract

The invention discloses a spraying device for a garden. The device comprises a spray head, a first pumping mechanism and a second pumping mechanism, wherein a mixing chamber is formed in the spray head; the first pumping mechanism is used for delivering water to the mixing chamber at a certain pressure; the second pumping mechanism is used for delivering a growth liquid to the mixing chamber at acertain pressure; the growth liquid and the water are mixed in the mixing chamber and then ejected through the spray head. The growth liquid (insoluble in water) is sprayed out immediately after mixedwith the water, the growth liquid is ejected together with the water without enough time to be separated from the water, so that the growth liquid and the water are more uniformly mixed, and the growth liquid is more uniformly sprayed on a lawn.

Description

technical field [0001] The invention relates to the technical field of garden maintenance, in particular to a garden spraying device for spraying liquid to lawns. Background technique [0002] In order to maintain the lawn, the lawn is usually sprayed with water so that the lawn can grow in a humid environment. Usually, the device for spraying water to the lawn includes a spray head and a pumping mechanism, which absorbs water into the container to Water is delivered at a certain pressure to the sprinkler head, and then the sprinkler head sprays the water at a certain pressure and speed on the lawn. [0003] In some cases, the lawn needs to grow the liquid medicine (such as liquid fertilizer or liquid medicine) to make the lawn grow better. For the convenience and sufficient supply of the medicine liquid to the lawn, the above-mentioned spraying device is usually used. The specific method is : The growth liquid is poured into a container filled with water in a predetermined...

AI Technical Summary

Problems solved by technology

[0005] When the growth liquid is insoluble in water and the density is smaller than water, the growth liquid poured into the container will eventually float on the liquid surface even after being stirred, so that the concentration of the growth liquid sprayed at different time intervals is different (for example, The water sprayed at the beginning has only a very small concentration of growth medicine, and the water sprayed at the end has a very high concentration of growth medicine, resulting in uneven spraying of the growth medicine)
