Abstract

The utility model provides a high-pressure cleaner which can automatically add cleaning agent in the process of cleaning. The high-pressure cleaner comprises a booster pump and a squirt gun; wherein, an ejecting channel is arranged between the water outlet of the booster pump and the water inlet of the squirt gun; the middle of the ejecting channel is connected with a liquid storage bucket by a connecting tube; and the connecting tube is provided with an one-way valve. When the squirt gun ejects low-pressure water, the negative pressure can be generated because of the sudden change of the sectional area of the middle of the ejecting channel, and the negative pressure can overcome the closing pressure of the one-way valve to open the one-way valve, so that the cleaning agent can be automatically mixed with the low-pressure water ejected by the squirt gun according to a certain proportion to clean the surface of an object to be cleaned. When the squirt gun ejects high-pressure water, the water in the ejecting channel can close the one-way valve to prevent the cleaning agent from entering into the squirt gun, and the cleaning effect can be achieved by high pressure.
