4 is a perspective view showing a connection portion of an electric toothbrush head according to an embodiment of the present invention.

Referring to FIG. 4, the third type bristle portion 1140 may be a portion in which bristles for cleaning the front and rear surfaces of the tooth are implanted. The third type parent part 1140 may be connected to the second type parent part 1130 through the connection part 1150. The connecting portion 1150 extends to both sides of the second type parent portion 1130 and may have a curved shape. The connecting portion may be formed of an elastic material of rubber or other synthetic resin. The protrusion 1150a is formed at one end of the connecting portion 1150, and the groove 1130a is formed at the side of the second parental portion 1130, and thus may be coupled in a press-fitting manner. Due to this structure, the second type parent part 1130 may be separated from the connection part 1150. In addition, the third type parent part 1140 may be detachably coupled to the connection part 1150 by a tilting part 1150b, which will be described later. Thus, when the bristles worn on the second hair part 1130 and the third hair part 1140 are worn, the second hair part 1130 and the third hair part 1140 are separated from the connection part 1150. Can be replaced. Meanwhile, the structure in which the second type parent part 1130 and the third type parent part 1140 are detachably coupled to the connection part 1150 is described in addition to the above-described structure, as well as the second type parent part 1130 and the third type parent part 1140. Any configuration is possible as long as it can be detachably coupled with the connection portion 1150.

In addition, the shape of the second type parent part 1130 and the third type parent part 1140 may be the same. Therefore, when the second type parent part 1130 and the third type parent part 1140 are replaced, the parts having the same structure need not be distinguished from each other, so compatibility is possible.

The third type parent part 1140 may not be disposed on the side of the first type parent part 1120. As a result, the first bristles 1120, which will be described later, may not interfere with the rotation of the bristles brushed on the third bristle 1140. In addition, since the third hair part 1140 is not disposed on the side of the first hair part 1120, the volume of the distal end of the electric toothbrush 1000 inserted deeply into the oral cavity becomes small, so that there is a feeling of heterogeneity and brushing in the oral cavity. It can reduce discomfort.

Meanwhile, brushing can be performed in various ways. Among the methods, the method of sweeping the front and rear of the teeth by rotating in the direction of the occlusal surface by being located parallel to the deep gingival toothbrush is called a rotation method. The rotation method is recognized as one of the most effective brushing methods at present, as it removes the germ layer and protects the gums.

The electric toothbrush 1000 may have a structure in which the third type parent part 1140 is capable of reciprocating tilting motion with respect to the connection part 1150 in order to implement a brushing form by the rotation method. Specifically, grooves 1141a are formed at end portions disposed at both ends along the longitudinal direction of the third type parent portion 1140, and a tilting portion 1150b that is rotatable may be disposed at the connection portion 1150. The tilting portion 1150b of the connecting portion 1150 may be inserted into the groove 1141a of the third type parenting portion 1140, and the tilting portion 1150b acts as a rotating shaft, and thus, the third type parenting portion 1140 Can be tilted relative to the connecting portion 1150. In this case, the rotation of the tilting unit 1150b may be performed by the rotating motor 1151. The rotating motor 1151 may change the direction of application of the current according to a predetermined time, and the rotation direction may be repeatedly changed. The rotating motor 1151 may be supplied with power through a battery. For example, since the connection protrusion 1150a is made of a conductor and current flows, current transmitted from the battery may be supplied to the rotating motor 1151. The power of the rotating motor 1151 is connected to a shaft (not shown) connected to both sides through a gearbox 1152 including various gears to rotate the shaft. The rotational movement of the shaft is transmitted to the rotating shaft 1154 coupled to the tilting portion 1150b through a shaft and a gearbox 1153 coupled to one end thereof, and the tilting portion 1150b reciprocates relative to the connecting portion 1150 It can be a tilting exercise. Therefore, the third type parent part 1140 coupled to the tilting part 1150b may be a reciprocating tilting motion with respect to the connection part 1150. The tilting portion 1150b has a flat plate shape, and extends the torque of the rotating shaft in the radial direction to transmit it to the third type mother portion 1140, so that the rotational motion of the third type mother portion 1140 can be facilitated.

Hereinafter, the effect of the electric toothbrush 1000 according to the embodiment of the present invention will be described.

The electric toothbrush 1000 according to the embodiment of the present invention includes a first parenteral part 1120 and a second parenteral part 1130, and as the brushing is performed, the first parenteral part 1120 and the second parenteral part (1130) can be brushed secondary to the occlusal surface of the tooth in the same position, there is an effect that can be effective and hygienic brushing.

In addition, the electric toothbrush 1000 includes a third-type parent part 1140, and while the first-type parent part 1120 and the second-type parent part 1130 clean the occlusal surface of the tooth, the third-type parent part 1140 ) Since the front and rear surfaces of the teeth are cleaned, a sufficiently hygienic brushing may be possible even if the electric toothbrush 1000 is moved less.

In addition, the electric toothbrush 1000 includes a notification unit 1210, and the notification unit 1210 may generate a notification in an appropriate washing time unit of the same tooth to induce correct brushing of the electric toothbrush 1000 user.

In addition, the electric toothbrush 1000, since the first parenteral part 1120 can rotate with respect to the base 1110, the third parenteral part 1140 is not disposed on the side of the first parenteral part 1120, The bristles that have been planted in the third parent part 1140 may not interfere with the rotational movement of the first parent part 1120.

In addition, since the electric toothbrush 1000 is brushed while the second-type parent part 1130 and the third-type parent part 1140 vibrate in the ultrasonic frequency band, the motion of water and toothpaste molecules flowing between the teeth is activated. , Hygienic brushing can be performed.

In addition, since the electric toothbrush 1000 is capable of reciprocating tilting motion with respect to the connecting portion 1150, the third type parent part 1140 can realize a brushing form by the rotation method, which is an efficient brushing method.

In addition, the second type 1130 and the third type 1140 of the electric toothbrush 1000 are substantially the same in shape, and can be separated from the base 1110 and / or the connection 1150, respectively. When the bristles worn on the 2nd bristle part 1130 and the 3rd bristle part 1140 are worn, it is easily replaceable.

In addition, since the shape of the second parenteral part 1130 and the third parenteral part 1140 of the electric toothbrush 1000 is formed with concave portions at both ends extending along the longitudinal direction, the second parenteral part 1130 Balanced arrangement is possible with the circular first type parent part 1120, and the third type parent part 1140 has a convex part disposed on both sides of the concave part complementary to the shape of the connection part 1150, brushing. It can be firmly combined so as not to separate in the middle.
