Description

Interdental brush assembly

The present invention relates to an interdental toothbrush assembly, and more particularly, to an interdental toothbrush assembly in which the brush is easy to take out, which is easily handled by the elderly, and the number of parts is reduced to improve the assembly.

An example interdental toothbrush for removing foreign matter between teeth is disclosed in Utility Model Registration No. 2000-0013032, an example of which is shown in FIG.

This interdental toothbrush has a brush 16 comprising a brush rod 10 and a swivel 11, a handle 12 and a cap 13. The brush rod 10 and the swivel 11 of the brush 16 are combined in a structure that can be disassembled and combined using the respective tapered protrusions 20 and the recesses 21, and the swivel 11 is the handle 12. It is inserted into the swivel seating groove 14 in the head portion of the head to be rotated at a predetermined angle around both pins 15 as a central axis, the rear end of the swivel 11 and the swivel ( 11 is provided with a support jaw 18 to selectively support the hanger 17 at the rear end of the 11 is a structure that can be firmly fixed to the bent state and the standing state of the entire brush (16).

The interdental toothbrush of this structure allows the brush 16 to be rotatable so that it can be used for removing foreign matter between the molar teeth located inside the mouth and removing foreign matter between the incisors, while the brush 16 is centered around the pin 15 during use. It is rotated and cannot use smoothly.

In addition, since the interdental toothbrush as described above is made of a brush 16, a swivel 11, a handle 12 and a cap 13, the number of parts is large, it is inconvenient to increase the manufacturing cost and to manage.

In addition, for storage when the brush 16 is not used, the brush stand 10 is taken out from the groove 21 to be inserted into the hollow of the handle 12, and then the cap 13 is disposed at the end of the handle 12. This storage work is inconvenient to store by binding to.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an interdental toothbrush assembly whose structure is improved to simplify the removal and storage of the brush with a simple structure.

The interdental toothbrush assembly of the present invention to achieve the above object is a hollow handle combined protective casing formed with a slit portion connected to the assembly hole is formed at the front end and the assembly hole is formed at the rear end and the longitudinal direction on the outer peripheral surface;

A brush holder having a neck portion coupled to one end of the brush in and out of the access hole and slidably coupled to the slit portion on an outer circumferential surface of the other end thereof, and a push rod extending from the neck portion and protruding to the outside of the protective handle combined with the handle. It characterized in that it was provided with.

The slit part may include a fixed slit part having a fixed jaw formed at the edge thereof to maintain a position where the brush protrudes into the access hole and limit movement of the neck part at an edge thereof;

A central slit portion extending from the fixed slit portion and moving the neck portion while the brush enters and exits the access hole;

It is characterized in that formed from the separation prevention slit portion extending from the central slit portion and in communication with the assembly hole and the first and second release prevention jaw to prevent the separation of the neck portion.

According to the above features of the present invention, the interdental toothbrush assembly of the present invention allows the brush to be easily taken out and used by slidingly coupling the brush holder to a protective handle combined with a handle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2 and FIG. 3 and FIG. 4 showing the interdental toothbrush assembly of the present invention in an exploded perspective view, the interdental toothbrush assembly has a brush access hole 37 formed at a front end thereof and an assembly hole ( A hollow handle combined protection barrel 30 having a slit portion 31, 32, 33 formed on the outer circumferential surface thereof and extending from the assembly hole 38 on the outer circumferential surface thereof;

The neck portion 42 which is coupled to the brush 50 which enters and exits the entrance hole 37 at one end and is slidably coupled to the slit portions 31, 32, and 33 on the outer circumferential surface of the other end, and the neck portion ( And a brush holder 40 extending from 42 to form a push rod 41 protruding to the outside of the handle combined protection container 30.

The slit portions 31, 32, and 33 are provided with fixing jaw 34 for maintaining the position where the brush 50 protrudes in the access hole 37 and restricting movement of the neck portion 42 at the edge thereof. A fixed slit portion 32, a central slit portion 31 extending from the fixed slit portion 32 and the neck portion 42 being moved while the brush 37 enters and exits the entrance hole 37; The separation preventing slit part 33 extending from the center slit part 31 and communicating with the assembly hole 38 and having first and second release preventing jaws 35 and 36 for preventing the neck part 42 from being separated. Is formed.

The handle combined protective barrel 30 around the access hole 37 has a truncated cone shape, and the brush 50 is formed in a cone shape so as to smoothly enter and exit the access hole 50.

This conical brush 50 facilitates entry and exit between teeth.

As shown in FIG. 3, when the push rod 41 is pushed in the left direction, the neck portion 42 passes over the first release prevention jaw 35 and passes through the central slit portion 31. And the neck portion 42 is fixed to the fixed slit portion 32 beyond the fixing jaw 34. At this time, the brush 50 is protruded into the entrance hole 37, and in this state to hold the handle combined protection barrel 30 by hand and remove foreign substances or tartar while reciprocating the brush 50 between the teeth.

In addition, when not in use, the pusher 41 is pushed in the right direction, as shown in FIG. 4, so that the neck portion 42 is positioned between the first and second release preventing projections 35 and 36. ) To enter the entrance 37. In this case, when the brush 50 is not used, the brush 50 is prevented from being contaminated from external foreign matters by entering the combined protective container 30.

The present invention as described above is not limited to the above embodiments without departing from the spirit and scope of the present application can be carried out by adding a number of modifications.

The interdental toothbrush assembly of the present invention as described above allows the brush holder to be easily taken out and used by slidingly coupling the brush holder to the protective handle for both handles and to carry easily.
