Description

  The present invention relates to a portable oral care device, and more particularly to a portable oral care device capable of extending a handle.

  Ordinary toothbrushes are about 15 cm long and some are as small as 8 cm, which are convenient to carry, but the handle is too short to hold. In the “toothbrush with folding tongue coating” of Patent Document 1, the tongue coating brush is attached to the handle with a hinge. Although it is conceivable to extend the handle with such a hinge, it is difficult to use because the handle is bent at the hinge portion during use.

  Japanese Patent Application Laid-Open No. H10-228707 discloses a “stomach-in-mouth cleaning sponge brush” that wipes off dirt adhering to the mouth with a sponge. It is desirable to shorten the handle so that it is convenient for carrying. However, if the handle is shortened, it is suitable for carrying. However, it is difficult to hold the handle because it is short.

The mating protrusion 4 is engaged. The annular groove 5a can engage the engaging protrusion 4 with the annular groove 5a even when the first handle 2a rotates and shakes when the brush portion 1 is pulled out. In the engaged state, the wall of the annular groove 5a abuts on the engaging protrusion 4, so that the first handle 2a is retained and the state can be maintained. The engaging protrusion 4 can be engaged with the annular groove 5a and can be retained. However, when the force protrusion is applied and pulled out, the first handle 2a is detached from the storage hole 3.
