Abstract

In the present invention, the head portion provided with the bristles is made transparent or semitransparent so as to be detachable from the handle portion of the main body, and the LED is provided in the handle portion so that the emitted light is diffused to the head portion, And to provide a toothbrush having an LED capable of reducing costs.

Description

TOOTHBRUSH WITH LED < RTI ID = 0.0 >

The present invention relates to a toothbrush, and more particularly, to a toothbrush having an LED capable of irradiating teeth and gums while brushing an LED light source having a therapeutic effect and germicidal effect of gum disease.

[0004] Patent No. 10-1209525 (Electric Firstsol) discloses a technique relating to a powered toothbrush in which disinfection and tooth whitening treatment are performed in an oral cavity when an ELID unit is attached to the toothbrush.

FIG. 1 is a side view showing the structure of a conventional electric toothbrush. FIG. 1 shows a handle 10 having a vibrating body 20 and a bristle assembly 40 having an engaging space for engaging with the vibrating body 20 The bristle assembly 40 includes a bristle body 80, 90 provided with a brush, an LED unit 50 mounted on the bristle bodies 80, 90 for disinfection and treatment of teeth in the mouth, A first connector 60 provided inside the first solo body to connect the LED unit 50 and the driving power source 30 and a second connector 70 provided inside the vibrator 20, The brush bristle bodies 80 and 90 include a first bristle body 80 and a second bristle body 90 which are formed by a double injection molding method.

Therefore, disinfection in the oral cavity and whitening treatment of teeth can be performed by the light emitted from the LED unit 50.

However, when the bristle assembly 40 is separated from the handle 10, the connectors 60 and 70 are exposed to the outside, which is not advantageous in terms of electrical insulation. In addition, in order to replace the bristle bodies 80 and 90 There is a problem that the LED unit 50 installed in the bristle hair main bodies 80 and 90 is also replaced and wasted.

That is, the lifetime of the LED is about 30,000 to 50,000 hours, but the lifetime of the bristles is much shorter than that of the LED, so that unnecessary replacement of the LED unit 50 is costly.

Therefore, in the present invention, the head portion provided with the bristles is made transparent or semitransparent so as to be detachable from the handle portion of the main body, and the LED is provided in the handle portion so that the emitted light is diffused into the head portion, The present invention provides a toothbrush having an LED capable of reducing costs by allowing replacement.

A toothbrush having an LED of the present invention

A handle which is provided with a battery, a projection formed on the upper side with a threaded portion formed thereon, an LED protruding from an end of the projection,

And a head portion having a bristle shape formed of a transparent or semitransparent material and having an insertion groove formed at one side thereof so that the projection is inserted and fastened.

In the present invention, since only the LED is exposed from the handle, the electrical insulation is excellent, and the head portion is made of a transparent or translucent material, thereby diffusing the light emitted from the LED, so that the replacement cost is very low .

1 is a view showing a cross-sectional structure of a conventional electric toothbrush.
Fig. 2 is an exploded cross-sectional structural view of the present invention. Fig.
Fig. 3 is a joint cross-sectional structural view of the present invention. Fig.

The present invention will be described with reference to FIGS. 2 and 3 attached herewith.

2 is an exploded cross-sectional view of the present invention, and is largely composed of a grip portion 100 and a head portion 200.

The handle 110 includes a battery 110 inside and a protrusion 150 integrally protruding from an upper end of the handle 100. A threaded engagement portion 151 is formed around the protrusion 150 have.

The protrusion 150 has a structure in which the protrusion 150 is communicated with the inside of the handle 100 and the LED 160 is mounted on the end of the protrusion 150. The protrusion 150 is formed in a cylindrical shape, ) Are exposed.

At this time, the space between the outer periphery of the LED 160 and the protrusion 150 is kept air-tight so as not to generate a space, or is sealed so that water does not permeate from the outside by a packing or a sealing material.

A switch 120 is provided on the rear side of the handle 100. The switch 120 is fastened to the handle by a lower cover as described in the registration practice 20-0462094, And a terminal board is provided to selectively contact the terminal portion provided at the inner lower end of the handle 100 so as to supply and cut off power.

As another alternative, a button-shaped switch may be provided on the outer side of the handle 100.

Accordingly, when the switch 120 is turned on, power is supplied from the battery 110 to the LED 160 through the wiring.

The head part 200 is formed of transparent or semitransparent material and has bristles 210 like a normal toothbrush and an insertion groove 220 is formed on the lower side so that the protrusion 150 can be inserted inward.

In addition, a threaded engagement portion 230 is formed on the inner circumference of the insertion groove 220 to be screwed with the engagement portion 151 of the projection 150.

3, the handle 100 and the head 200 are coupled by screwing.

Therefore, light emitted from the LED 160 is diffused through the transparent or translucent head 200, and is irradiated into the oral cavity during brushing, thereby having a therapeutic effect.

In the case of the red LED, the blue LED may be irradiated with the wavelength of 600 to 650 nm to have the gum treatment effect and the regenerating effect. In the case of the blue LED, the wavelength of the red LED may be 420 to 470 nm And has a sterilizing effect.

A PCB 140 on which the vibration motor 130 is mounted is provided inside the handle 100 so that when the switch 120 is turned on, power is supplied from the battery 110 to the vibration motor 130 A vibrating force is generated. This vibrating force is transmitted to the head unit 200 to have a gum massage effect.

A guide 141 in the form of a plate having an elastic force is coupled to the upper side of the PCB 140 in order to maximize the transmission of the vibration power. The guide 141 extends to the inside of the protrusion 150, 160 are fixed.

Accordingly, the vibration force is transmitted to the head part 200 coupled to the protrusion 150 through the guide 141, thereby maximizing the therapeutic effect together with the light source from the LED 160. [
