The present invention discloses a vacuum suction type rejuvenation instrument with a drainage function, which comprises a casing, a top end of the casing is formed with a head, a transparent suction nozzle is embedded in the head, and a vacuum pump is arranged in the casing. The control board and the drain pipe, the air inlet and the suction nozzle of the vacuum pump are connected through the air pipe, the gas nozzle seat is formed at the rear end of the air inlet nozzle, and the blue LED light source is arranged adjacent to the gas nozzle seat, and the vacuum pump and the blue LED light source respectively Electrically connected to the control board, the vacuum pump is controlled by the control panel to generate a negative pressure and the blue LED light source is controlled to light. The housing comprises a front shell and a rear shell, the head is located on the front shell, and the front shell is provided with a drainage hole. The inner side of the front shell is provided with a column joint, and the column joint is connected with the drain hole, one end of the drain pipe is sleeved on the column joint, and the other end of the drain pipe is connected to the exhaust port of the vacuum pump. This creation enhances the effects of blue light therapy, prevents glare from spreading, and increases the lifespan.本創作公開了一種具有排水功能的負壓吸附式煥膚儀，其包括有殼體，殼體的上端形成有頭部，頭部上嵌設有透明的吸氣嘴，殼體內設有真空泵、控制板和排水管，真空泵的進氣口和吸氣嘴通過氣管連通，吸氣嘴的後端形成有氣嘴座，氣嘴座的相鄰處設有藍光LED光源，真空泵和藍光LED光源分別電性連接於控制板，藉由控制板而控制真空泵產生負壓以及控制藍光LED光源點亮，殼體包括有前殼和後殼，頭部位於前殼上，前殼上開設有排水孔，前殼的內側設有柱狀接頭，且柱狀接頭與排水孔相連通，排水管的一端套接於柱狀接頭，排水管的另一端連通於真空泵的排氣口。本創作可提高藍光理療效果、能防止眩光擴散以及提高使用壽命。
