    • Provided is an oral cleaning device capable of ensuring a sufficient ejection pressure for a cleaning liquid while employing a small and low-cost electric air pump with a low output. An oral cleaning device is provided with an air-tightly closable cleaning liquid tank 2 which stores a cleaning liquid, a cleaning liquid supply passage 24 which has an ejection port 4a for ejecting the cleaning liquid into the oral cavity on one end and an introduction port 23a open inside the bottom part of the cleaning liquid tank 2 on the other end, and an electric air pump 44 which supplies air into the cleaning liquid tank 2 to pressurize the inside of the cleaning liquid tank 2. The cleaning liquid inside the cleaning liquid tank 2 is supplied to the ejection port 4a through the cleaning liquid supply passage 24 by air pressure inside the cleaning liquid tank 2. An air introduction hole 71 which is open on the midway part of the cleaning liquid supply passage 24 is provided and part of the air supplied to the cleaning liquid tank 2 from the air pump 44 is supplied to the cleaning liquid supply passage 24 through the air introduction hole 71 to eject the cleaning liquid in a pulsatile manner from the ejection port 4a.
