Modern people often have teeth discolored to yellow or black brown due to external factors such as coffee or smoking or internal factors such as diseases. This is called tooth discoloration, and tooth discoloration is a problem for many people in modern society where the importance of appearance as well as health problems of teeth is increasing. In fact, according to these concerns, the technology related to tooth whitening is gradually developing, and the market size related to tooth whitening is also increasing.

Tooth whitening refers to a procedure for whitening discolored teeth by simplifying the structure of a colorant formed on the teeth by using an oxidizing action such as high concentration of hydrogen peroxide.

Teeth whitening includes a dental procedure using a relatively high concentration of hydrogen peroxide and a self-whitening method using a whitening toothpaste, a whitening agent, a whitening gel, and a whitening patch containing a relatively low concentration of hydrogen peroxide.

Among these, dental procedures are excellent in their effectiveness, but they are cumbersome and costly because they have to visit the dentist directly. . Among them, the method of using a tooth whitening gel, toothpaste, and whitening agent is widely used as a general whitening method. do. Therefore, in order to promote the oxidation reaction, a process of polishing the teeth with the applied whitening agent or the like is required.

However, devices such as brushes have been developed to allow the whitening agent to be applied to the tooth surface, but the currently released or developed whitening agent application device uses a whitening agent directly on a brush, etc. and rubs as if brushing or brushing. There is a limit in terms of convenience and efficiency because it has to be applied, and the polishing process also has to be directly rubbed by holding a tool such as a brush. That is, because of this point, there are many cases where the whitening agent is not applied to the entire tooth surface depending on the user's behavior of using the appliance, and the part where the interdental or brush does not reach well, such as the teeth deep inside the mouth, or the back of the teeth There are cases where the whitening agent is not applied to the skin. Even if the whitening agent is evenly applied, there is a problem in that efficient whitening is difficult because a sufficient polishing step is not performed.

In addition, a general whitening brush has a straight neck, which causes inconvenience to use. In addition, although abrasion of the brush and the like occurs well, a mechanism to replace it has not been developed, so there is a burden of newly purchasing the entire application mechanism.

Accordingly, it is possible to further activate the action of the whitening agent through the polishing step, beyond the efficient application of the whitening agent to the entire tooth surface. There is a demand for the development of a possible electric whitening brush.

In more detail, the electric whitening brush capable of replacing the head according to the present invention is divided into a first neck part 111 and a second neck part 112 because a part of the length of the neck 11 is bent, and the The brush member 12 is inserted into the front end, and the second neck portion 112 extends in the longitudinal direction, the head portion 1 having a hollow 16 formed at the end thereof, and the hollow ( 16) a lower case portion coupled to the other side of the body portion 2 and the body portion 2 provided with a vibration module 4 having an insertion member 21 inserted into the one side and generating vibration therein ( 3) can be included.

The head part 1 has a configuration in which the brush member 12 in direct contact with the teeth is inserted. As shown in FIG. 3 , the head part 1 includes an extended neck 11 , and the neck 11 is partially bent in length to form a first neck part 111 and a second neck part 112 . can be distinguished. At this time, the neck 11 is preferably bent vertically, but is not limited thereto, and may be bent at an angle of 70 to 120 degrees. The first neck portion 111 is an upper portion of the neck 11 in which the brush insertion hole is formed so that the brush member 12 can be directly inserted. The second neck part 112 is formed to form an angle with the first neck part 111 and to extend downward. When the user's electric whitening brush is used, the distance between the hand and the oral cavity is maintained, and the force applied by the user's hand is applied to the brush. It is a configuration that can be transmitted to

The first neck part 111 and the second neck part 112 are formed to form an angle, and as shown in FIG. 4 , the brush member 12 is inserted in parallel with the first neck part 111 so that the user can use the electric whitening brush. The gripping portion and the brush member 12 are maintained at an angle. Accordingly, the user can more freely manipulate or use the electric whitening brush compared to the case where it is formed in a straight line like a general brush or brush, so that the brush can contact the entire tooth.

As will be described later, the overall external shape of the electric whitening brush with a replaceable head according to the present invention may have a shape similar to that of a general toothbrush or one-tuft toothbrush. Therefore, if necessary, the electric whitening brush according to the present invention can be used not only for applying and polishing a whitening agent, but also for brushing teeth like a general electric toothbrush, and can also be used for the purpose of applying other medicines or nutrients. It is natural to have Accordingly, the whitening agent referred to herein may be various, such as a whitening agent, a whitening gel, a whitening toothpaste, a general toothpaste, a medicine for gums or teeth, a nutritional supplement, and the like.

However, the whitening agent and the like are not necessarily applied only through the electric whitening brush that can replace the head according to the present invention, but may also be applied by other devices. In this case, the function of the present invention can be concentrated on efficiently polishing the teeth so that the applied whitening agent or the like can properly perform the function. In addition, due to vibration generated during polishing, a function of evenly applying a whitening agent, etc. to a part that has not been applied, such as a tooth located deep in the interdental space or the oral cavity, may additionally be performed. That is, after applying a whitening agent to the teeth using another instrument or hand, the present invention can be used to spread evenly over the entire area of the teeth and simultaneously polish the teeth.

As shown in FIG. 4 , the brush member 12 may include a filament and a locking protrusion 121 for preventing separation from the tip of the first neck part 111 . At this time, the locking jaw 121 may be formed by fusion of the lower end of the filament. In this case, the lower end of the fused filament is preferably formed in the same shape as a disk having a larger diameter than the filament bundle.

A plurality of filaments may be implanted in a configuration to become a hair having a thin thickness to form a respective bundle. At this time, the bundle formed by the filament is also referred to as a tuft. For example, a toothbrush formed by inserting one tuft is classified as a one-tuft or single-tuft type toothbrush.

The electric whitening brush capable of replacing the head according to the present invention may be formed by implanting at least one tuft. At this time, when the one-tuft method is adopted, miniaturization and high density of the brush member are possible, and the brush, that is, the filament, can be in contact between teeth or deep inside the oral cavity, for example, up to the back of wisdom teeth or molars. do. On the other hand, when a plurality of tufts are employed, the filaments can three-dimensionally contact the teeth. Accordingly, there is an advantage in that a whitening agent can be applied over the entire tooth even with a small movement, and an efficient polishing function is performed. That is, the number of tufts is not necessarily limited to one, and a plurality of tufts may be employed as necessary.

In the case of manufacturing a one-tuft type brush member, a plurality of filaments may be densely inserted and implanted to form a bundle at the tip of the first neck portion 111 . In this case, the filament may be made of ultrafine hair, normal hair, silicone hair, rubber hair, nonwoven fabric, and the like.

It may be made to further include. The separation preventing member 13 may have a hole in the center through which a brush, that is, a filament communicates through it, and is inserted into the brush insertion hole of the first neck portion 111 in a state where the filament is inserted to pass through the separation preventing member ( 13) is inserted to prevent separation of the brush member 12 .

In addition, the brush member 12 may be inserted using an ultrasonic coupling method using a head plate. That is, after cutting the bottom surface in a state where the filament is inserted into the head plate and fixed, the lower hair can be fusion-fixed to the inside of the first neck part 111 using ultrasonic waves.

Alternatively, the filament may be injected while being inserted into the tip of the first neck part 111 through the in-mold injection method, and the filament is fixed to metal or plastic such as a brush or a makeup brush and then forcibly fixed to form a double bond structure. you might be able to do it

A method for inserting and fixing the brush member 12 to the first neck portion 111 is not limited to the above-described method, and any method capable of firmly fixing the brush member 12 may be employed without limitation. .

The brush member 12 may have any one shape selected from among a flat surface, a concave-convex shape, and a concave shape on a surface in contact with the teeth. That is, the filament may be formed to form a shape such as a cone, a truncated cone, a branch, etc. so that the entire outer shape protrudes convexly in the state in which the plurality of filaments are concentrated. That is, the one-tuft brush member 12 may be formed to have a silicon brush shape or a cup-shaped trim or an inclined trim when viewed in cross section as a whole.

Meanwhile, the head unit 1 may further include a discharge port for discharging water or a whitening agent through the tip of the first neck unit 111 . The discharge port may be formed separately between the filaments, or may be formed to pass through the filaments as necessary. As such, by including the discharge port, the whitening agent, etc. can be discharged intermittently or continuously through the head unit 1 while using the electric whitening brush, as well as applying the whitening agent after squeezing it to the brush, thereby increasing convenience. .

The hollow 16 formed in the head 1 may have a circular cross section, and on the inner surface of the hollow 16 there is a head engaging groove 18 and a head guide groove 17 formed by being engraved along a part of the inner circumference. can be formed. In addition, the insertion member 21 formed in the body portion 2 may also be formed in a cylindrical shape having a circular cross section to correspond to the hollow 16 , and inserted into the head guide groove 17 and the head locking groove 18 . A head fixing protrusion 211 to be formed may be formed.

Looking at the coupling method of the head part 1 and the body part 2 in more detail, as shown in FIG. 5 , the head fixing protrusion 211 is drawn in from the lower side to the upper side along the head guide groove 17 , It is fitted into the head locking groove 18 through the subsequent rotation.

Since the head part 1 and the body part 2 are combined in this way, it can be easily replaced when the life of the head part 1 becomes loose or the brush member 12 is worn out, etc., and the head part 1 ), the rest of the configuration can be used semi-permanently.

As shown in FIG. 3 , the head 1 may have a neck 11 formed toward the body 2 from the portion where the brush is implanted. At this time, the neck 11 may be divided into a first neck portion 111 and a second neck portion 112 by bending a portion of the length. As described above, the first neck portion 111 has a configuration in which the brush member 12 is inserted into the tip, and the second neck portion 112 is configured to extend downward from the bent portion.

The mounting surface 14 may be continuously cut to a portion where the diameter is widened so as to be coupled with the body portion 2 along the second neck portion 112 to have a curved surface with an inclination. By forming the mounting surface 14 in this way, the user can properly place his or her thumb while applying or polishing a whitening agent, thereby providing convenience.

In addition, the lowermost end of the neck 11 has a circular cross-section, the neck extension member 15 is formed at the lower end, and a hollow 16 is formed inside it, so that the insert member 21 can be firmly fitted. have. In this case, the neck extension member 15 may have a length of 5 to 20 mm, and preferably may be formed to have a length of 8 to 12 mm. That is, the length from the lowermost end of the mounting surface 14 to the interface between the head portion 1 and the body portion 2 may be 8 to 12 mm. In addition, the neck extension member 15 may have a diameter of 10 to 25 mm, preferably, may have a diameter of 12 to 18 mm. This may correspond to a diameter of the body portion 2 and the lower case portion 3 having a diameter of 10 to 25 mm, preferably having a diameter of 12 to 18 mm. By adopting such a configuration, it is possible to prevent shaking or loosening of the coupling due to the force applied by the user during application or polishing of the whitening agent, etc., and the user's applied force can be stably transmitted to the toothbrush, Alternatively, a feeling of pressure applied when the brush member 12 presses the teeth during abrasive action can be delivered as it is. In addition, since the neck extension member 15 is formed in this way, not only the neck 11 part is replaced, but a part included in a part of the body is replaced. can be done easily. In addition, since the interface between the head part 1 and the body part 2 is formed on the lower side compared to the relatively thin part of the neck 11, penetration of whitening agents, toothpaste drugs, etc. can also be prevented or reduced.

In addition, as shown in FIG. 3 , the neck 11 may be positioned so that the second neck part 112 is parallel to one side when viewed from above. Preferably, in a state in which the second neck part 112 is biased to one side, the second neck part 112, the neck extension member 15, The passing surface 14 may be formed naturally. In addition, through this, the second neck portion 112 has a naturally curved shape, which enables the user to apply or polish the tooth surface at various angles in response to the curved shape. By adopting this configuration, the present invention can make a user feel similar to a real manual toothbrush when using the electric whitening brush, and has a similar appearance to an existing manual toothbrush, so that the user does not feel awkward in using the present invention, and the application action Alternatively, the bearing capacity may increase during abrasive action.
