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.

  Hereinafter, a portable oral care device according to the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of a portable toothbrush in the portable oral care device of the present invention. The handle 2 is in a degenerated state. A portable toothbrush 50 a is taken up as the portable oral care device 50. The portable toothbrush 50a has a length of about 8 cm, and is shorter than the usual 15 cm, and is suitable as a portable toothbrush. The brush part 1 consists of a toothbrush 1a. The handle 2 includes a first handle 2a and a second handle 2b. Since the first handle 2a is stored in the storage hole 3 of the second handle 2b, the handle 2 of the portable toothbrush 50a is shortened as a whole. it can. The portable toothbrush 50a can be a disposable product.

  As shown in FIG. 1, the first handle 2a is stored in the storage hole 3 of the second handle 2b. In that case, the two engaging protrusions 4 of the first handle 2a are in contact with the inner surface of the storage hole 3 of the second handle 2b. Although there is friction, the first handle 2a can be easily pulled out.

  FIG. 2 is a front view of a portable toothbrush in the portable oral care device according to the present invention. The handle 2 is in an extended state. FIG. 3 is a plan view of a portable toothbrush in the portable oral care device according to the present invention. The handle 2 is in an extended state. As shown in FIG. 2 and FIG. 3, the first handle 2a can be pulled out from the storage hole 3 of the second handle 2b to lengthen the handle. Therefore, the handle 2 can be about 13 cm. Since the handle 2 is long, it is easy to hold the handle 2 by hand.

  As shown in FIG. 2, when the first handle 2a is pulled out from the accommodation hole 3 of the second handle 2b and extended to the maximum, the first handle 2a is engaged with the annular groove 5a on the left side of FIG. 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.

  4 is a cross-sectional view taken along line AA in FIG. As shown in FIG. 4, an engagement recess 5 is provided on the inner periphery of the accommodation hole 3 of the second handle 2 b. The engaging recess 5 is an annular groove 5a extending in the circumferential direction. In FIG. 4, the inner diameter of the annular groove 5a is slightly larger than the inner diameter of the storage hole 3. However, if the engagement protrusion 4 is to be engaged tightly with the annular groove 5a, the annular groove 5a is trimmed. Then, it can be coped with by forming the inner diameter of the annular groove 5 a smaller than the inner diameter of the storage hole 3.

  FIG. 5 is a front view of the brush portion 1 and the first handle 2a shown in FIG. As shown in FIG. 5, the first handle 2 a is provided with a plurality of engaging protrusions 4. A ball 6 containing a care agent was provided at the rear end of the brush portion 1. The care agent contains a dentifrice. Prior to brushing the teeth, the ball 6 is pressed with a finger to push the dentifrice into the toothbrush 1a. The ball 6 is sealed at the outlet and can be broken by pressure. In addition, the ball 6 can be pulled and removed after the dentifrice is pushed out. Moreover, you may arrange | position the ball | bowl 6 in the toothbrush 1a. In that case, the toothpaste is pushed out by chewing the ball 6 with teeth.

Therefore, the handle 2 of the portable toothbrush 50a can be shortened.

  FIG. 7 is a front view of a portable sponge brush in the portable oral care device according to the present invention. The handle 2 is in an extended state. The internal structure of the handle 2 is the same as that of the portable toothbrush 50a shown in FIGS. The portable sponge brush 50b removes dirt in the mouth while rotating the sponge brush 1b, but it may be easy to rotate without tightly engaging the annular groove 5a and the engagement protrusion 4. According to this, the first handle 2a can be held between the thumb and forefinger and rotated, and the second handle 2b can be held so as not to move with the ring finger and the palm. Since the sponge brush 1b and the first handle 2a can be exchangeably attached to the second handle 2b of FIG. 1, the sponge brush 1b and the first handle 2a may be attached as a set to the portable toothbrush 50a. .

  FIG. 8 is a view in which the interdental brush 7 is attached to the rear end of the second handle 2b. FIG. 9 is a view in which the toothpick 8 is attached to the rear end of the second handle 2b. FIG. 10 is a view in which a tongue coating drop plate 9 is attached to the rear end of the second handle 2b. The interdental brush 7, the toothpick 8, and the tongue coating plate 9 can be attached to the second handle 2b in a replaceable manner. The first handle 2 a may be attached to the interdental brush 7, the toothpick 8, and the tongue coating plate 9, and may be attached to the front end of the second handle 2 b in a replaceable manner.
