The present invention relates to a new concept of technology for freely spraying a scalp cosmetic liquid for scalp care or a paint for kraffiti (spray painting) while eliminating clogging of a sprayer.

In general, human scalp is covered with a lot of hair except for severe hair loss, so unlike other skins, a large amount of various waste products including oxidized fat are deposited on the surface and pores of the scalp. .

The deposition of such wastes clogs pores or infects bacteria and adversely affects not only the scalp, but also the hair roots and hair shafts, leading to a great obstacle to hair growth and growth.

In addition, along with harmful components of the dye, environmental pollution, stress, etc. cause damage to scalp cells, skin rashes, swelling, itchy scalp, and various scalp diseases such as inflammation.

Accordingly, consumers' interest in the scalp essence for improving the scalp is increasing, and in the past, it was a method of absorbing the scalp essence by directly applying the scalp essence to the scalp and then rubbing it.

However, the conventional method has a cumbersome problem of washing hands every time, and it is difficult to evenly apply the scalp essence to the scalp as a whole.

As a prior art for solving the above problems, "Patent Registration No. 1397594, name/scalp and skin care device with an intuitive display installed and improved spraying efficiency of a spray device" has been disclosed.
