In order to obtain better cleaning effect and ensure oral safety, the existing oral irrigator is generally used with oral cleaning liquid, and the product using the capsule to supplement oral cleaning liquid is convenient to use and can continuously and conveniently supplement oral cleaning liquid.

[0003] However, the oral cleaning liquid capsule of the existing oral irrigator product is usually arranged at the upper part of the product, and the user needs to press the oral cleaning liquid capsule to inject oral cleaning liquid into the water storage cavity of the oral irrigator during use.
