Description

Electric sprayer with replaceable nozzle tip

The present invention relates to an electric sprayer equipped with a replaceable nozzle tip that sprays water or a cleaning solution to a place requiring cleaning, such as a car or a window.

In general, when a car or windshield becomes dirty with contaminants such as dust, a method of wiping with a mop is used to clean it. Wipe it off with a rag to finish.

At this time, for washing, it is necessary to put water in a container or draw water from the outside using a hose, so it is not only inconvenient to use, but also has a problem that space restrictions follow, and it is difficult to control the amount of water used. There was a problem of wasted water.

Alternatively, in order to clean the car body or windshield more neatly, the user directly rubs the cleaning solution with a rag to make foam, or a separate device for generating foam is provided and the cleaning power is improved by spraying it on the car or the windshield.

As such, recently, portable sprayers that can be easily carried and used by users have been proposed. However, products that can be washed with water are bulky, so they are difficult to carry and are often used in an installation type, so their utility is low.

As disclosed in Republic of Korea Patent Publication No. 10-1761842 'Electric Car Wash', portable electric car washes currently on the market are equipped with a hand device so that the user can lift it up easily in a soft water bag into which water is injected. It protruded and took up space, and it was difficult to hold the hand device and work due to the large size of the soft water bag.

In addition, the conventional electric car wash can be used while connected to the vehicle cigar jack, and has a long hose several meters long that can be sprayed around the car. spray

Although the electric car wash with this structure is portable, it can only be used when it is connected to a vehicle cigar jack for power supply. There was a tangible problem.

In addition, in the prior art, a device for spraying foam in various forms according to the washing purpose had to be separately provided, and there were many components to be prepared for car washing, which made it difficult to carry. In addition, there was a cost burden to provide each spraying device according to the use, and a problem occurred that the cleaning power was lowered because a foam of a suitable form could not be used for cleaning.
