Instant self-cleaning hair comb

Abstract

An instant self-cleaning hair comb includes a lower shell and an upper shell. A spring and a push button are sequentially arranged between the lower shell and the upper shell, and a comb and a push plate are sequentially arranged outside the lower shell and the upper shell. The comb is configured to comb out the hair. The push plate is configured to push out the hair twined on the comb. The lower shell is configured to fix the comb and compress the spring. The spring is configured to be connected with the push button and the lower shell. The push button is configured to adjust the spring and the lower shell. The upper shell is configured to be connected with the lower shell and fix the push button and the spring. The efficiency of cleaning the hair comb is increased to shorten the cleaning time.
