As shown in Figs. 3, 4 and 5, a portable interdental toothbrush A according to the first embodiment of the present invention comprises: a bottle 1 of cleaning solution in the form of a bottle receiving a cleaning solution S containing fluorine; a brush assembly 2 in which a hole 21 of the assembly slots for a bottle neck portion of the cleaning solution tube 1 to be introduced and assembled, is formed at one end, and a brush 22 is fixed to the other extreme; and an elastic ball 3 which can expand and contract and is disposed at a tip of the tube 1 of the cleaning solution inside the brush assembly 2.

[0012] The cleaning solution tube 1 is made of synthetic resins to make its convenient manufacture, and comprises, as shown in Figs. 3, 4 and 5, a body 10 of the tube in which a cleaning solution S is received, an assembly projection 11 with a protruding diameter smaller than that of the body 10 of the tube, in which a discharge orifice 12, to be equivalent to a bottleneck part that extends from the body 10 of the tube with a smaller diameter than that of the body 10 of the tube and which discharges the cleaning solution S, is formed at the tip, and a part 13 of Assembly thread is formed on the outside of a lower part, and a coupling projection 14 is formed in a separate part between the body 10 of the tube and the assembly projection 11. On both sides of the body 10 of the tube, flat portions are formed to add labels or advertising. To prevent damage, a reinforcing rim 12a is formed which is thickened at the tip in which the discharge orifice 12 of the assembly projection 51 is formed, thereby reinforcing the resistance of the discharge orifice.

A plurality of projections 14a are formed in the coupling projection 14, the positions of the projections 14a are different, and their state assembled with the brush assembly 2 varies depending on the positions of the projections 14a, thus identifying the assembled state with brush set 2 easily.

In the brush assembly 2, the brush 22 is fixed to one end and the hole 21 of the assembly slots is formed at the other end. In a lower surface 23 contacting the projection 14 for coupling the hole 21 of the assembly grooves, insertion grooves 23a are formed to couple the projections 14a to one another and introduce the projections 14a.

A part 24 of negative thread, for coupling the assembly thread part 13, is formed inside the lower part of the hole 21 of the assembly groove, to be assembled with the cleaning solution tube 1.

A plurality of outlet flow slots 25a is formed in a longitudinal direction in an inner wall of a central space, which is located in the center of the hole 21 of the assembly slot and into which the elastic ball 3 is inserted, whereby the cleaning solution S discharged through the discharge orifice 12 of the cleaning solution tube 1 is discharged along the outlet flow slots 25a. The discharge of the cleaning solution S is controlled in the following manner. If the tube 1 of the cleaning solution is rotated in an opening direction, in a state in which the cleaning solution tube 1 and the brush assembly 2 are threadedly engaged, more cleaning solution is discharged through the the outlet flow slots 25a. If the tube 1 of the cleaning solution is rotated in a direction of tightening, then the elastic ball 3 is pressed and the outflow slots 25a are pressed. This prevents the cleaning solution from passing through the outflow slots 25a, thereby stopping the discharge of the cleaning solution S.

To secure the brush 22 to the brush assembly 2, a plurality of through slots 26a are formed in a longitudinal direction on an outer surface of the fixing rod 26, fixed at one end of the brush 22, and the fixing rod 26 it is inserted and fixed inside a fixing hole 27 at one end of the brush assembly 2, thereby fixing the brush 22 to the brush assembly 2. As an alternative example, a method in which a cylindrical fixing rod 26 fixing the brush 22 at one end is inserted into the interior of the fixing hole 27 of the brush, on an inner surface from which a plurality of slots are formed. step to form passage grooves, is obviously included within the scope of the present invention.

Once the brush 22 is fixed to the brush assembly 2, the cleaning solution S is supplied to the brush 22 through the discharge orifice 12 of the cleaning solution tube 1, the outflow slots 25a of the central space 25 of the brush assembly 2, and the passage slots 26a of the brush assembly 2.

The elastic ball 3 is inserted into the central space 25 of the brush assembly 2, the lower part of which is in contact with the tip in which the discharge hole 12 of the assembly projection 11 of the cleaning solution tube 1 is formed , and the lateral surface and the upper part of which are in contact with the central space of the assembly 2, which becomes an important element for controlling the discharge of the cleaning solution S. That is, the discharge control of the cleaning solution S is performed in the following manner. If the cleaning solution tube 1 is rotated in an opening direction in a state in which the cleaning solution tube 1, the elastic ball 3, and the brush assembly 2 are threadedly engaged, more solution is discharged cleaning through the outflow slots 25a of the central space 25, since the elastic ball 3 and the central space 25 are not pressed (See Figs 7a and 7b). If the cleaning solution tube 1 is rotated in a tightening direction, then the tip, in which the discharge orifice 12 of the assembly projection 11 of the cleaning solution tube 1 is formed, acts to press the ball 3. elastically and subsequently press the outlet flow slots 25a of the central space 25 to close said outflow slots 25a, which prevents the cleaning solution S from passing through the outflow slots 25a, thereby stopping the discharge of the cleaning solution S (see Figs 6a and 6b).

In the present invention, the elastic ball 3 can be used, however, it is not limited thereto. Instead, a metal ball can be inserted into the central space and moved forward and backward to open and close the passage slots 26a of the brush assembly 2 to control the discharge of the cleaning solution S. Accordingly, a metal ball may be used in place of the elastic ball 3, and the elastic ball 3 and the metal ball shall be interpreted to be identical during the interpretation of the present invention.
