However, in the conventional technique as described above, the push button which is pushed vertically projects into the locking projection, which is as small as the projection, in the narrow space on the flat cross section of the toothbrush base. Since it is installed in a structured structure, if the user's hand has moisture, not only will it not be able to slip and apply full force, but it will also require considerable force to push, which makes it inconvenient to use. There was a disadvantage that there was.

The present invention has been made in view of such conventional problems. Even when the user has moisture, the toothpaste with the internal organs can be easily extruded by applying a small force by the user. An object of the present invention is to provide a toothbrush with a built-in toothpaste.

[0009]

In order to achieve such an object, in a toothbrush having a toothpaste according to the present invention, a pressing device and a pump assembly are provided in an upper portion of a toothpaste storage tub having the toothpaste incorporated therein. A toothbrush having a toothbrush push-out passage formed therein, which is configured to be coupled to push out the toothbrush by a pumping action, and which communicates with one side of the toothbrush base to the inside and the outside. A button mounting groove is formed, and a pressing device that is pressed in the horizontal direction is mounted and coupled with a lifting rod so as to move up and down above and below a normal toothpaste pushing passage formed inside the toothbrush base. And

More specifically, it is a toothbrush which is constructed by combining a toothbrush storage tub containing a gel-type toothpaste and a toothbrush base and is pushed out by a pumping action, in which a piston is provided inside and a hole is formed at the bottom. A bottom plug that closes the vents provided, and an upper part of the toothpaste storage tub comprising:
