The present invention relates to a portable hygienic toothbrush which has a toothpaste function having a toothpaste extruding function of a structure that is configured to be opened and closed by folding the handle of the toothbrush to extrude and replace the toothpaste in the handle of the toothbrush. The main focus is to make it easy to carry and use by combining the toothbrush and toothpaste in the same body so that the toothpaste can be extruded in the handle of the toothbrush.

Conventionally, the structure in which toothpaste is stored and extruded in the toothbrush body is extruded in the form of a piston, which is complicated in structure, and the movement range of the piston is large when used, which makes the handling inconvenient. There was a flaw, and the toothpaste extrusion hole drilled in the toothbrush extruded part was always open, so foreign substances such as dust were buryed and there was a defect such as unsanitary.

The present invention is configured so that the handle is divided into two lengths to the toothbrush body in order to reduce the overall drawbacks of the prior art by storing the toothpaste therein to easily extrude the toothpaste in the state of binding the handle so that it can be used sanitarily. If this is described in detail by the accompanying drawings as follows.

An extrusion passage 3 of the toothpaste 10 was formed in the toothbrush stand 1 to communicate with the toothpaste outlet 5 formed in the center of the toothbrush portion 2 in which the toothbrush 4 was placed. The toothpaste outlet 5 formed the guide groove 7 in the toothbrush part 2 by making the inner peripheral wall into the inclined circumferential wall 6 which was inclined downward. In the guide groove (7), the opening and closing plate (8) which is installed on the sloped circumferential circumferential wall (6) is pushed down.

Extrusion port of toothpaste 10 having a male thread formed at the distal end of the toothpaste tube 9 by forming a female screw on the toothpaste 10 injection port 3a side of the extrusion passage 3 located at the distal end surface of the toothbrush bar 1 ( 9a) was made to bind.

The flat cover 11 and the bottom cover 12 with the semicircle screw rod 12a installed on the flat part and the bottom of the toothbrush holder 1 having the toothpaste inlet 3a formed thereon are hinged ( 13) 13a (13a) to form a handle 14 by folding so as to fold material, the shape of the handle 14 is the upper and lower parts installed in the rear end by joining the semi-circular upper cover 11 and the lower cover 12 The upper and lower lids are joined by a cylindrical handle 14 to screw the support cap 15 into the joints of the semi-circular threaded rods 11a and 12a of the semicircular threaded rods 11a and 12a. (11) (12) formed on both sides of the upper cutting portion (16) (16a) and the lower cutting portion (17) (17a) to form both side guideways (18) (18a), but the lower cover (12) The gear rails 19 and 19a were formed in the lower cutting part 17 and 17a which were formed in the lower part.

In addition, in the center of the upper surface of the upper cover 11 was installed through a working hole 20 penetrated in the longitudinal direction.

In the cylindrical handle 14 formed as described above, the toothpaste extruded hole 9a formed at the distal end of the toothpaste tube 9 is bound to the inlet 3a formed at the distal end surface of the extrusion passage 3, and the toothpaste tube 9 is formed. Has implied.

In the state in which the toothpaste tube 9 is installed in this manner, the toothpaste extrusion hole 21 formed separately in a spherical shape is installed at the rear end of the toothpaste tube 9, but the mounting wheel 22 is formed at the center of the hole 21. ) And the gear rods 23 and 23a protrude from both sides to be geared to the gear rails 19 and 19a formed on the side guide paths 18 and 18a.

The present invention as shown in FIG. 1 is separated from the support cap 15, which binds the handle 14 in the state in which the handle 14 is cylindrically attached as shown in Figure 1, the upper and lower parts as shown in Figure 2 The cover (11) (12) is unfolded and the extruded port (9a) of the toothpaste tube (9) is coupled to the toothpaste inlet (3a) of the extrusion passage (3) to support it, and then the roll (21) to the toothpaste tube (9) The gear rods 23 and 23a protruding to both sides of the rolling hole 21 while being positioned inside the upper and lower cover 11 and 12 so as to be located at the rear end of the lower guide 11 are engaged with the gear rails 19 and 19a. When the upper and lower covers 11 and 12 are positioned at 18 and 18a, the upper and lower covers 11 and 12 are easily folded by the hinges 13 and 13a, and the upper and lower covers 11 and 12 are folded as the cylindrical handles 14. The mounting wheels 22 of the rolling holes 21 are attached to the upper cover 11 by binding the semicircle threaded rods 11a and 12a which are protruded and joined to the rear end of the support hole 15. It is to be installed so as to project slightly into the action hole 20 through the central portion.

In use, an opening and closing plate which is formed by inclined circumferential wall 6 in the toothpaste outlet 5 formed to penetrate through the extrusion passage 3 at the central portion of the toothbrush 4 in advance to reach the guide groove 7. 8) to push the rear opening the toothpaste outlet (5), and then pushes the mounting wheel 22 of the rolling hole (21) protruding into the action hole (20) of the handle (14) and the rolling hole (21) Gear rods 23 (23a) protruding to both sides of the tooth) are toothed to the gear rails (19) (19a) installed on the lower cutting portions (17) (17a) of the lower cover (12), and the toothpaste tube (9) While pressing the rear end of the toothpaste 10 is sent to the extrusion port (9a) is to be extruded to the toothpaste outlet 5 along the extrusion passage (3).

As such, according to the user's needs, an appropriate amount of toothpaste 10 is extruded, and then the opening and closing plate 8 is pushed in and the toothpaste outlet 5 is sealed and then brushed.

When the toothpaste 10 in the toothpaste tube 9 is completely consumed while being used in this manner, the upper and lower lids 11 and 12 that form the handle 14 in the reverse order of coupling the handle 14 are opened to the inside. Replace the empty toothpaste tube (9).

The present invention as described above is combined with a flat bottom cover formed in a semi-circular shape to accommodate the toothpaste tube in the cylindrical handle for easy replacement and to push the toothpaste in the toothpaste tube to easily push out, and the toothpaste is extruded The toothpaste outlet can be easily used to open and close the toothpaste outlet, so that the toothpaste can be used hygienically without being buried with foreign substances such as dust.
