The present invention is intended to provide an oral care device, which will be described in more detail with the drawings below, and the accompanying drawings are only examples for easily explaining the content and scope of the technical idea of the present invention, and are limited thereto. It is not, and the terms used are also intended to specifically describe the embodiments, and are limited to the corresponding terms and should not be interpreted.

As shown in Fig. 1, the oral care device 1 of the present invention has one side of the main body 2 having a substantially rod-like shape as a transparent hard head 21, and the other side of the main body 2 It forms the gripping part 23, and consists of a bending part 22 between the head part 21 and the gripping part 23.

The bending part 22 is made of a soft material so that it can be bent at a predetermined angle when an external force is applied.

Holding the gripping part 23 by hand, inserting the head part 21 into the mouth, and when the head part 21 touches the teeth, the bending part 22 bends and the internal electronic circuit operates to operate the transparent head part 21 The light emitting part 3 inserted inside of) emits light.

The light-emitting unit 3 may be applied by selecting one or more of the filament 31 or the LED 32, and various infrared rays such as far-infrared, mid-infrared, and near-infrared rays from the filament 31 or LED 32 Is radiated.

It is configured to irradiate infrared or ultraviolet light to the teeth in the oral cavity, the gums, and the inside of the cheek (hereinafter referred to as teeth).

Therefore, it is possible to expect various effects described in the effects of the invention together with a sterilizing action by infrared rays or ultraviolet rays irradiated to the teeth.

In addition, as shown in FIG. 2, a transparent detachable head 5 having a bristles 51 may be additionally combined with the head 21 to be used in the form of a toothbrush.

When used in the form of a toothbrush, the useful effect of the oral care device 1 can be naturally taken just by applying toothpaste to the bristles 51 and brushing teeth regularly.

The configuration can be viewed in detail as shown in FIG. 3.

The illustrated main body 2 is arbitrarily cut and expressed to express the internal configuration, and there may be various ways of assembling according to the production process.

One side of the rod-shaped main body 2 is a transparent hard head part 21, the other side of the main body 2 is a gripping part 23, and between the head part 21 and the gripping part 23 is the main body ( It is a position corresponding to the neck of 2) and is composed of a soft bending portion 22 so that the body 2 is naturally bent by an external force.

The head part 21, the bending part 22, and the gripping part 23 may be manufactured in an integrated form by a multi-injection molding method using a temperature difference.

The head part 21 has a hardness that does not wear out even if it touches or rubs a tooth, and the inside of the head part 21 is formed to have a hollow part 211 to form a space so that the light emitting part 3 can be inserted inside. Do it.

When the light emitting unit 3 is turned on, since infrared or ultraviolet light must pass through the head unit 21 and be exposed to the outside, the head unit 21 must be formed of a transparent material.

A wire (W) to supply power to the light-emitting part (3) is formed by being connected to the light-emitting part (3) behind the light-emitting part (3), and the wire (W) is covered so that the anode and the cathode are not short-circuited with each other. One end of the wires is coupled to the fixed terminal 41, and the other end of the wire is coupled to the variable terminal 42.

The electric wire (W) is inserted into a plurality of wire fixing grooves 223 formed on the inside of the main body (2), so that the position of the electric wire (W) is deviated from the position of the wire (W) even when the oral care device (1) shakes or bends.

The fixed terminal 41 and the variable terminal 42 are formed coupled to the fixed terminal groove 221 and the variable terminal groove 222 formed on the inner side of the main body 2, respectively, but no external force is applied to the main body 2 In the state, the fixed terminal 41 and the variable terminal 42 are formed to be slightly spaced apart, so that the oral care device 1 is configured to be short-circuited normally.

The fixed terminal groove 221 is located close to the center of the bending part, and the variable terminal groove 222 is located inclined to one side from the center of the bending part.

The end of the variable terminal 42 may be properly bent so that the variable terminal 42 does not come out of the main body 2 to be used as the inner power terminal 43. Of course, the electric wire W may be coupled to the end of the variable terminal 42 again so that the electric wire W may be connected to the separate inner power terminal 43.

A power supply means (B) is inserted into the holding portion (23) of the main body (2).

The power supply means (B) is portable by using a replacement alkaline battery, a rechargeable lithium-ion battery, or a NiMH (nickel metal hydride) battery that is replaced for charging. You can increase it.

Regardless of which power supply means (B) is used, since there are positive and negative electrodes, one of the positive and negative electrodes is contacted to the inner power terminal 43.

The rest of the pole is the inner power protruding inside the sealing cap 24 that seals the main body 2 to the opening 231 so that the power supply means B can be inserted and removed from the rear of the gripping part 23 It is configured to be in contact with the terminal 43.

The coupling method of the sealing cap 24 to the insertion part 231 may be various, but male and female screwing may be generally used. In this case, the outer power terminal 44 connected to the inner power terminal 43 is formed. Is formed so as to be exposed to one side of the cap so as to provide a contact means such as a cap terminal 45 at the end of the wire W extended from the light emitting part 3 but not connected to the fixed terminal 41 to be connected.

The head portion 21 of the main body 2 is formed of a solid and transparent material.

When the gripping part 23 of the main body 2 is formed of a soft material, the power supply means B and the inner and outer power terminals 43 and 44 may be short-circuited by an external force, and the gap between the sealing cap 24 Since water or foreign substances may penetrate into the interior of the main body 2 due to low waterproof and dustproof properties, the gripping portion is also formed of a solid material as possible.

The bending part 22 corresponding to the neck of the main body 2 must be appropriately bent by an external force according to an action to be described later, so it is formed of a soft material so that it is easily bent with a small external force and is not broken by a strong external force.

A detachable head 5 having a bristle 51 may be coupled to the head 21.

The detachable head 5 is formed with a plurality of bristles 51 coupled upwardly on the upper surface, and the lower portion of the detachable head 5 has a space in which the head 21 can be inserted.

When the oral care device (1) is used as a toothbrush, when rubbing the bristles (51) on the teeth, unlike the intention of the user, so as not to fall out or turn away, the locking jaw (52) in the space formed on the lower inner side of the detachable head (5) To form the coupling protrusion 53.

The locking jaw 52 is formed so as to surround the head 21 from the front and back to correspond to the direction of the force received when brushing teeth left and right, and the coupling protrusion 53 is a detachable head 5 when brushing teeth vertically. It is formed to protrude inward in the longitudinal direction so as not to turn away from the head part 21, and coupling grooves 212 corresponding to the coupling protrusions 53 are internally formed on both sides of the head part 21.

Therefore, when the detachable head 5 is coupled to the head part 21, the locking protrusions 52 of the detachable head 5 are in close contact with the front and rear of the upper surface of the head part 21, and at the same time, on the side of the head part 21 The coupling protrusion 53 of the detachable head 5 is internally coupled to the formed coupling groove 212 to have a rigid fixation.

As another coupling method of the detachable head 5, a rotation preventing surface 214 is formed on one surface of the head portion 21 of the main body 2, as shown in FIG. 4, and attached and detached to correspond to the rotation preventing surface 214. The coupling surface 54 is formed on the inside of the head 5, so that the combined detachable head 5 may not rotate unintentionally.

Looking briefly at the action, as shown in Fig. 5A, when no external force is applied when not in use, the bending part 22 of the main body 2 is not bent and is in a straight state, and thus the fixed terminal 41 and the variable terminal 42 is separated from each other and kept in a short-circuited state, so that the light emitting part 3 is not lit, and the power of the power supply means B is also maintained.

When the user uses the oral care device 1 as shown in FIG. 5(B), the gripping part 23 is held by hand, and the head part 21 or the detachable head 5 mounted on the head part 21 When pressed in close contact with the teeth in the mouth, the soft bending portion 22 is bent.

The gripping part 23 rotates in the opposite direction to which the force is applied based on the head part 21 in close contact with the tooth, and the soft banding part 22 becomes a rotating shaft and bends, so the internal space of the bending part 22 As this narrowly narrows, at the same time, the variable terminal 42 installed to one side away from the center of the bending portion 22 is a variable terminal coupled to the variable terminal groove 222 according to the bending of the bending portion 22 ( As one end of 42) rotates, the other end of the variable terminal 42 makes a circular motion and touches the fixed terminal 41 so that the internal circuit of the oral care device 1 is energized. The power supply means (B) supplies power to the light-emitting part 3 so that the light-emitting part 3 is turned on, so that the user's dental health can be improved by irradiating light to the teeth.

After using the oral care device (1), if the head part (21) is separated from the teeth, it returns to the shape of (A) in Fig. 5 by the elastic restoring force of the bending part (22), so the variable terminal (42) is again a fixed terminal. Since the power is disconnected from the 41, the light emitting part 3 is turned off.

As shown in FIG. 6, the length of the variable terminal 42 may be shortened, and the bending part 22 may be formed closer to the gripping part 23 than the head part 21.

When configured as described above, in addition to pressing the head portion 21 to the detachable head 5 to the teeth, the light emitting portion 3 may be turned on by easily energizing the gripped thumb.

As shown in (A) or (B) of FIG. 7, arbitrary partition walls are erected on both sides of the variable terminal 42 so that the variable terminal 42 can be configured to be bent while having an elastic force so that it is upward or downward. When the variable terminal 42 is configured as described above, regardless of whether the head portion 21 or the detachable head 5 is pressed against the teeth, the flexible bending portion 22 is pressed with a finger and the variable terminal 42 is bent. By arbitrarily adjusting the direction upward or downward, lighting of the light emitting unit 3 can be controlled.

When the variable terminal 42 is raised by pressing the bending part 22 from the lower side, the internal circuit is energized and the light emitting part 3 is turned on. On the contrary, if the variable terminal 42 is lowered from the upper side, the internal circuit Is cut off, and the light emitting part 3 is turned off.

As shown in FIG. 8, by protruding into the bending part 22 to narrow the vertical gap of the empty space, the variable terminal 42 is formed in an inward shape, and the variable terminal 42 is inwardly formed on the other side of the inside. By forming, a pair of variable terminals 42 are formed to face each other but slightly spaced apart.

In this case, as well as the operation according to the presence or absence of tooth pressure of the head part 21 or the detachable head 5, the pair of variable terminals 42 come into contact with each other even by the small grip of the gripped hand, so that the light-emitting part ( 3) can be turned on.

9 to 10, it is possible to use the LED 32 instead of the filament 31. In the case of FIG. 9, a hemispherical high-brightness LED to a UV (infrared) LED are applied, and in the case of FIG. 10, a chip-type high-brightness LED to a UV LED is applied. In order to facilitate assembly of several LEDs 32, the LED 32 is used in a form coupled to a separate LED substrate 33, and the LED substrate 33 is fixed inside the head unit 21. It may be coupled by forming a substrate coupling groove 213 in the inside of the head portion 21 so as to correspond to the side of the LED substrate 33 so as to increase.

In the case of a visible light LED, since different wavelengths of light according to various colors have different effects on the human body, various colors may be arbitrarily combined in one light-emitting unit 3.

In the case of UV LED, it is already applied in various fields with excellent sterilization effect, so the efficacy of LED is omitted.

Therefore, if the oral care device 1 having a combination of various configurations as described above is used, bacteria in the oral cavity can be easily sterilized, and a number of additional useful effects can be obtained.

As described above, the most preferred embodiments of the present invention have been described in the detailed description of the present invention, but various modifications are possible within the scope not departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention is not limited to the above embodiments, but the scope of protection should be recognized from the techniques of the claims to be described later and equivalent technical means from these techniques.
