Description

[Technical Field]

[0001] The present disclosure relates to a toothbrush and toothbrush set that includes an attention-focusing element that can generate interest in tooth brushing and can easily guide young children's tooth brushing habits. [Background technology]

[0002] Generally, a toothbrush is an oral hygiene tool used to brush teeth using toothpaste for oral hygiene and dental health. It has a long rod-shaped handle with a head with toothbrush bristles attached at one end, and the user inserts the head into the oral cavity to brush their teeth.

[0003] However, if the toothbrush user is an ordinary infant or child, they dislike brushing their teeth and find it boring, so there is a need to stimulate their curiosity, help them concentrate, and guide them in brushing their teeth.

[0004] For this reason, most toothbrushes simply have various decorations on the handle, but with toothbrushes with such decorations, the decorations are hidden by the hand and cannot be seen with the naked eye while brushing teeth. In other words, even if a person begins brushing their teeth out of curiosity after seeing the decorations, they soon become discouraged because they cannot see the decorations while brushing their teeth, which makes it difficult to brush their teeth faithfully.

[0005] Even if the child grasped the handle so that they could see the ornament, they had difficulty focusing their attention on the ornament simply because they had to force their eyes to look down.

[0006] Furthermore, when a parent brushes a child's teeth, the child must open their mouth as wide as possible so that the parent can see the inside of their molars. However, over time, the mouth may close naturally, or the child may become bored and intentionally change the shape of their mouth to interrupt the brushing. Therefore, constant reminders and motivation are necessary to ensure that the child maintains the proper mouth shape, such as "A" or "B," while brushing their teeth. However, decorations drawn or attached to the handle are not useful for attracting attention during brushing.

[0007] Furthermore, the decoration attached to the handle cannot be replaced until the end of the toothbrush's lifespan, which poses a problem in that the interest-inducing effect of the decoration decreases over time.

[0008] Meanwhile, for family members including infants or children, toothbrushes of family members are usually stored together in a toothbrush holder installed in a toilet washbasin or the like, and used together. However, since the heads containing most of the toothbrush bristles are located in the storage space of the toothbrush holder, when multiple toothbrushes are stored, there is a risk that the bristles of each toothbrush may come into contact with each other, which is unhygienic. Summary of the Invention [Problem to be solved by the invention]

[0009] To provide a toothbrush and a toothbrush set which can induce tooth brushing habits in young children by detachably providing an attention-focusing member which stimulates the curiosity of young children and can be easily seen with the naked eye continuously even during tooth brushing.

[0010] To provide a toothbrush and a toothbrush set that can induce a child's tooth brushing habit continuously by periodically replacing attention-gathering members with various characters that can arouse the child's interest.

[0011] To provide a toothbrush and a toothbrush set that are easy to distinguish, can be easily stored in a toothbrush holder without interfering with other toothbrushes when not in use, and are hygienic. [Means for solving the problem]

[0012] According to one embodiment, a toothbrush is provided that includes: a toothbrush head including a toothbrush portion having a plurality of toothbrush bristles; a toothbrush handle connected at one end to the toothbrush head; and an attention-focusing member having a detachable portion detachably provided at the other end of the toothbrush handle and an image portion extending from the detachable portion and embodying a character.

[0013] Here, the toothbrush of this embodiment may include a support part having one end extending from the other end of the toothbrush handle along the toothbrush head direction and fixed inside the toothbrush handle, and a connecting member having an attachment part provided at the other end of the support part and fixed to the other end of the toothbrush handle.

[0014] In this case, the detachable portion of the attention concentration member may be detachably provided on the mounting portion of the coupling member through magnetic force.

[0015] The toothbrush handle may be detachably coupled to the toothbrush head, and when coupled, the support portion of the coupling member may extend from one end of the toothbrush handle and be inserted into the inside of the toothbrush head.

[0016] In this case, either one of the attachment portion of the connecting member and the detachable portion of the attention concentration member may be formed of a magnet, and the other may be formed of a metal that is attached and detached through the magnetic force of the magnet, or both the attachment portion of the connecting member and the detachable portion of the attention concentration member may be formed of a magnet that is attached and detached through magnetic force.

[0017] Meanwhile, instead of a detachable structure using magnetic force including the connecting member, the toothbrush of this embodiment may include a rotating support member that is rotatably mounted on the other end of the toothbrush handle with the longitudinal direction connecting the toothbrush head and the toothbrush handle as the rotation axis, and the detachable portion of the attention concentration member may be detachably mounted on the rotating support member.

[0018] Here, a coupling groove may be formed in the rotation support member, and the detachable portion of the attention concentration member may be formed as a coupling protrusion inserted into the coupling groove.

[0019] At this time, a step portion may be formed inside the coupling groove, and a locking portion that is locked to the step portion when inserted may be formed on the coupling protrusion.

[0020] Therefore, the coupling protrusion may be inserted into the coupling groove along the rotation axis direction of the rotation support member, or may be inserted into the coupling groove along a direction perpendicular to the rotation axis direction.

[0021] Meanwhile, a coupling groove may be formed at the other end of the toothbrush handle, and a coupling protrusion that detachably couples to the coupling groove may be formed at the detachable portion of the attention concentration member, or a coupling groove may be formed at the detachable portion of the attention concentration member, and a coupling protrusion that detachably couples to the coupling groove may be formed at the other end of the toothbrush handle.

[0022] The detachable portion of the attention concentration member may have a cap shape that wraps around the other end of the toothbrush handle and is detachably connected to it, or the other end of the toothbrush handle may be configured to have a cap shape that wraps around the detachable portion of the attention concentration member and is detachably connected to it.

[0023] Meanwhile, the image portion of the attention concentration member may be at least one of a picture, a photograph, or a three-dimensional model of a character or toy.

[0024] At this time, the image portion can be manufactured using a lenticular printing technique.

[0025] The toothbrush of this embodiment may further include a light-emitting unit provided in the attention-focusing member for emitting light to the outside.

[0026] According to another embodiment, there is provided a toothbrush set including: a toothbrush head including a toothbrush portion having a plurality of toothbrush bristles; a toothbrush handle connected at one end to the toothbrush head; a connecting member having a support portion whose one end extends from the other end of the toothbrush handle in the direction of the toothbrush head and is fixed inside the toothbrush handle; and an attachment portion provided at the other end of the support portion and fixed to the other end of the toothbrush handle; an attention concentration member having a detachable portion detachably provided at the attachment portion of the connecting member via magnetic force and an image portion extending from the detachable portion and embodying a character; and a toothbrush holder attached to a wall or mirror in a space where the toothbrush is used, and having the detachable portion of the attention concentration member detachably provided thereon via magnetic force. [Effects of the Invention]

[0027] The removable attention-focusing member has the advantage of stimulating the interest of young children and naturally guiding them to develop good tooth brushing habits.

[0028] The detachable part rises considerably above the tip of the toothbrush, is positioned at a child's eye level, and can be rotated 360 degrees, which has the advantage that the part can be easily seen with the naked eye while the child is brushing their teeth.

[0029] Taking advantage of the feature that allows parents to see the relevant parts with the naked eye while brushing their children's teeth, parents can become the relevant characters and role-play with their children, or have a virtual conversation with them, stimulating their children's imagination and guiding them to make the right mouth shape.

[0030] The attention-focusing parts with various characters can be replaced at any time, which has the advantage of encouraging children to brush their teeth continuously without getting bored.

[0031] The attention-focusing member maximizes the distinctiveness of each toothbrush, and when not in use, it can be easily stored in the toothbrush holder without interfering with other toothbrushes, which has the advantage of improving hygiene. [Brief explanation of the drawings]

[0034] The toothbrush includes a toothbrush head including a toothbrush part having a plurality of toothbrush bristles; a toothbrush handle connected at one end to the toothbrush head; and an attention-focusing member having a detachable part detachably provided at the other end of the toothbrush handle and an image part extending from the detachable part and embodying a character.

[0035] Hereinafter, various embodiments will be described in detail with reference to the drawings. The embodiments described below can be implemented in various different forms. In order to more clearly describe the features of the embodiments, detailed descriptions of matters that are well known to those skilled in the art to which the following embodiments pertain will be omitted.

[0036] On the other hand, in this specification, when a certain component is "connected" to another component, this includes not only the case where the component is "directly connected" but also the case where the component is "connected via another component in between." Furthermore, when a certain component "includes" another component, this does not mean that the other component is excluded, but that the other component may be further included, unless otherwise specified.

[0037] Additionally, terms including ordinal numbers such as "first" or "second" used herein may be used to describe various components, but the components should not be limited by the terms. The terms are used only to distinguish one component from another.

[0038] FIG. 1 is a perspective view schematically showing a toothbrush according to one embodiment, FIG. 2 is a perspective view schematically showing a separable connection structure between the toothbrush handle and toothbrush head of FIG. 1, FIG. 3 is a perspective view schematically showing a state in which a child's gaze is focused on an attention concentration member, and FIG. 4 is a perspective view schematically showing a state in which the toothbrush of FIG. 1 is separably attached to a toothbrush holder through magnetic force.

[0039] Referring to FIG. 1, a toothbrush 100 according to one embodiment may be configured to include a toothbrush head 110 including a toothbrush portion 111 having a plurality of toothbrush bristles 111a; a toothbrush handle 120 connected at one end to the toothbrush head 110; a connecting member 130 having a support portion 131 extending and fixed inside the toothbrush handle 120 and an attachment portion 132 provided at the other end of the support portion 131 and fixed to the other end of the toothbrush handle 120; and an attention concentration member 140 having a detachable portion 141 provided at the attachment portion 132 of the connecting member 130 via magnetic force and an image portion 142 extending from the detachable portion 141 and embodying a character.

[0040] Here, the support part 131 of the connecting member 130 can be fixed by extending one end from the other end of the toothbrush handle 120 along the direction of the toothbrush head 110, and can be provided on the toothbrush handle 120 by a double injection manufacturing method.

[0041] With further reference now to FIG. 2, the toothbrush handle 120 may be releasably coupled to the toothbrush head 110 .

[0042] That is, the toothbrush handle 120 may be manufactured separately from the toothbrush head 110, and when connected to each other, the support portion 131 of the connecting member 130 may extend from one end of the toothbrush handle 120 and be inserted into the toothbrush head 110.

[0043] Therefore, when the toothbrush bristles 111a formed on the toothbrush part 111 of the toothbrush head 110 are worn out due to repeated tooth brushing, only the toothbrush head 110 can be easily replaced and used in combination with the toothbrush handle 120.

[0044] Meanwhile, the mounting portion 132 of the connecting member 130 and the detachable portion 141 of the attention concentration member 140 can be detachably connected through magnetic force, and in this case, one of the two can be formed of a magnet, and the other can be formed of a metal that can be attached and detached through the magnetic force of the magnet.

[0045] Of course, the mounting part 132 of the coupling member 130 and the detachable part 141 of the attention concentration member 140 may be formed of a magnet that is attached and detached by magnetic force.

[0046] The image portion 142 of the attention concentration member 140 may be composed of at least one of a picture, a photograph, or a three-dimensional model of a character or toy.

[0047] Of course, the image portion 142 may include the user's name alone or in addition to the name to enhance the user's identification.

[0048] At this time, the image portion 142 is manufactured using a lenticular printing technique to enhance the visual effect.

[0049] Meanwhile, in this embodiment, the toothbrush 100 is disclosed as being formed by separately manufacturing the toothbrush head 110 and the toothbrush handle 120 and connecting them to each other using the support portion 131 of the connecting member 130. However, this is not limited to this, and the toothbrush head and toothbrush handle can be integrally injection molded, or at the same time, they can be more easily manufactured by plastic injection molding with a magnet inserted into the end of the toothbrush handle instead of the connecting member during integral injection molding.

[0050] In conclusion, when an infant or child brushes their teeth by themselves or when a parent brushes their teeth, the toothbrush 100 of this embodiment can arouse the interest of the infant or child through the image unit 142 of the attention concentration member 140, making tooth brushing more fun and interesting.

[0051] Referring further to FIG. 3, when rotating the toothbrush 100 to brush the upper teeth and then the lower teeth, if the image part 142 of the attention concentration member 140 is rotated together with the detachable part 141 of the attention concentration member 140 attached to the mounting part 132 of the connecting member 130, the gaze of the infant or child being brushed can be continuously focused on the image part 142.

[0052] Meanwhile, although not shown in detail, the toothbrush 100 of this embodiment may further include a light-emitting unit on the attention-concentrating member 140 for emitting light to the outside.

[0053] Here, the light emitting unit may include an LED (Light Emitting Diode) accommodated inside the image part 142 of the attention concentration member 140 and a dry cell battery for supplying current to the LED, and the image part 142 may be made of a transparent material so that light emitted through the LED can be irradiated to the outside. In this case, the attention concentration member 140 may have a structure in which the image part 142 can be separated from the detachable part 141 to conveniently attach or replace the LED.

[0054] Therefore, when an infant or child brushes their teeth in a dark environment, the toothbrush 100 of this embodiment not only attracts more interest from the infant or child by emitting light to the outside using the light-emitting unit, but also allows the infant or child to brush their teeth accurately.

[0055] Meanwhile, referring to FIG. 4, the toothbrush 100 of this embodiment may constitute one toothbrush set 10 including a toothbrush holder 200 provided on a wall or mirror in a space where the toothbrush 100 is used.

[0056] More specifically, the toothbrush holder 200 can be detachably fixed to a wall or mirror in a bathroom, for example, as an example of a space where the toothbrush 100 is used, and the attention-focusing member 140 of the toothbrush 100, i.e., the detachable part 141, can be detachably fixed to one side of the toothbrush holder 200 through magnetic force.

[0057] Here, when the detachable part 142 of the attention concentration member 140 is formed of a magnet, the detachable part 142 may be made of a metal that can be attached and detached through magnetic force, and when the detachable part 142 of the attention concentration member 140 is formed of a metal, the toothbrush holder 200 may be made of a magnet.

[0058] As a result, the toothbrush 100 can be detachably fixed to the toothbrush holder 200 by attaching the mounting portion 132 of the connecting member 130 to the detachable portion 142 through magnetic force while the attention concentration member 140 is fixed to the toothbrush holder 200 by the detachable portion 141.

[0059] Of course, the toothbrush 100 can be detachably fixed to the toothbrush holder 200 directly by the mounting portion 132 .

[0060] That is, when the mounting portion 132 of the connecting member 130 is made of metal, the toothbrush holder 200 is made of a magnet, and the mounting portion 132 is attached to one side of the toothbrush holder 200 through magnetic force, so that the toothbrush 100 can be directly and detachably fixed to the toothbrush holder 200 without the need for the attention concentration member 140.

[0061] In this case, if the mounting portion 132 of the connecting member 130 is formed of metal and the corresponding detachable portion 141 of the attention concentration member 140 is formed of a magnet, it is preferable that the toothbrush holder 200 is formed of a magnet that is attached and detached to the detachable portion 141 through magnetic force.

[0062] Therefore, according to the toothbrush set 10 of this embodiment, the toothbrush 100 can be easily attached to and detached from the toothbrush holder 200, and at this time, the toothbrush head 110 can be maintained in a state of floating independently in the front space of the toothbrush holder 200 without external interference or contact, allowing the toothbrush bristles 111a to dry quickly and improving hygiene.

[0063] In this embodiment, a structure in which the toothbrush 100 is fixed horizontally to the toothbrush holder 200 is disclosed, but this is not limited thereto, and a structure in which the toothbrush 100 is fixed vertically to the toothbrush holder 200 can also be applied.

[0064] That is, the area of ​​the attachment portion 132 of the connecting member 130 or the detachable portion 141 of the attention concentration member 140 is increased along the longitudinal direction of the toothbrush handle 120, and the increased area can fix and separate the toothbrush 100 to the toothbrush holder 200 in the vertical direction, and in this case, a detachable structure using a magnet and metal can be applied to the increased area and the toothbrush holder 200.

[0065] In another method, the toothbrush holder 200 may be fixed to a mirror or wall in the form of a horizontal plate, or may be fixed to a mirror or wall in a bent form consisting of a vertical plate and a horizontal plate, and the toothbrush 100 may be fixed or separated vertically by fixing the mounting portion 132 of the connecting member 130 or the detachable portion 141 of the attention concentration member 140 to the upper or lower surface of the horizontal plate. In this case, a detachable structure using a magnet and metal may be used for the fixation or separation.

[0066] Of course, apart from the mounting portion 132 of the connecting member 130 or the detachable portion 141 of the attention focusing member 140, another magnet or metal can be provided on one side of the toothbrush handle 120, and the toothbrush 100 can be fixed or separated vertically to the toothbrush holder 200 by the magnet and metal.

[0067] Figure 5 is a perspective view schematically showing a toothbrush according to another embodiment, Figure 6 is a cross-sectional view schematically showing key parts along the longitudinal direction connecting the toothbrush handle and toothbrush head of Figure 5, Figure 7 is a cross-sectional view along line I-I' of Figure 6, Figure 8 is a perspective view schematically showing key parts of another embodiment of the rotating support member and attention concentration member of Figure 6, and Figure 9 is a cross-sectional view along line II-II' of Figure 8.

[0068] Referring to FIG. 5, a toothbrush 300 according to another embodiment may be configured to include a toothbrush head 310 including a toothbrush unit 311 having a plurality of toothbrush bristles 311a, a toothbrush handle 320 connected at one end to the toothbrush head 310, a rotating support member 330 rotatably provided at the other end of the toothbrush handle 320 with the longitudinal direction connecting the toothbrush head 310 and the toothbrush handle 320 as a rotation axis, and an attention concentration member 340 having a detachable portion 341 detachably provided on the rotating support member 330 and an image portion 342 extending from the detachable portion 341 and embodying a character.

[0069] Here, the rotation support member 330 may be formed in a cylindrical shape having a fastening protrusion 331 that is inserted into and fastened to a fastening groove 321 formed at the other end of the toothbrush handle 320, but is not limited to this. A fastening protrusion may be formed on the toothbrush handle 320, and a fastening groove into which the fastening protrusion is inserted and fastened may be formed on the rotation support member 330.

[0070] The rotation support member 330 may have a coupling groove 332a formed on one side of its outer surface 332, which is exposed to the outside when inserted and fastened to the other end of the toothbrush handle 320, into which the detachable part 341 of the attention concentration member 340 is detachably inserted.

[0071] Therefore, the detachable part 341 of the attention concentration member 340 may be formed of a coupling protrusion 341a inserted into the coupling groove 332a. That is, the coupling protrusion 341a forming the detachable part 341 may be inserted into the coupling groove 332a along a direction substantially perpendicular to the rotation axis direction of the rotation support member 330.

[0072] At this time, a step portion 332a-1 may be formed inside the coupling groove 332a, and a locking portion 341a-1 to be locked to the step portion 332a-1 may be formed on the coupling protrusion 341a.

[0073] In addition, the attention concentration member 340 may have the locking portion 341a-1 formed of an elastic rubber material or a soft resin material so that the attention concentration member 340 can be detached from the rotation support member 330 in a replaceable manner.

[0074] Of course, instead of forming the locking portion 341a-1, the coupling protrusion 341a may be formed of an elastic rubber material or a flexible resin material, and configured so that the coupling protrusion 341a is inserted into or separated from the coupling groove 332a by a press-fit method.

[0075] Also, although not shown in detail, a coupling protrusion may be formed on one side of the rotation support member 330 instead of the coupling groove 332a, and a coupling groove corresponding to the coupling protrusion may be formed on the attachment / detachment part 341 of the attention concentration member 340. Thus, the coupling protrusion of the rotation support member 330 may be inserted into or separated from the coupling groove formed on the attachment / detachment part 341 of the attention concentration member 340, thereby allowing the attention concentration member 340 to be fixed to or detached from the rotation support member 330.

[0076] The rotation support member 330 may have a coupling groove 332a formed on one side of its outer surface 332, which is exposed to the outside when inserted and fastened to the other end of the toothbrush handle 320, into which the detachable part 341 of the attention concentration member 340 is detachably inserted.

[0077] Therefore, the detachable part 341 of the attention concentration member 340 may be formed of a coupling protrusion 341a inserted into the coupling groove 332a. That is, the coupling protrusion 341a forming the detachable part 341 may be inserted into the coupling groove 332a along a direction substantially perpendicular to the rotation axis direction of the rotation support member 330.

[0078] Meanwhile, referring further to Figures 6 and 7, the rotating support member 330 may have at least one fixing protrusion 331a formed along the circumferential direction on the outer peripheral surface of the fastening protrusion 331, and therefore, a plurality of fixing grooves 321a corresponding to the at least one fixing protrusion 331a may be formed along the circumferential direction on the inner peripheral surface of the fastening groove 121 of the toothbrush handle 320.

[0079] At this time, the at least one fixing protrusion 331a may be coupled to and separated from the plurality of fixing grooves 321a in a forced press-fit manner while the rotation support member 330 is rotated, but is not limited thereto. The at least one fixing protrusion 331a may be configured to be coupled to and separated from the plurality of fixing grooves 321a in an elastically compressed state when the rotation support member 330 is rotated, and then elastically returned to its original position.

[0080] In conclusion, when the rotation support member 330 rotates around the longitudinal direction connecting the toothbrush head 310 and the toothbrush handle 320 as a rotation axis with the fastening protrusion 331 inserted and fastened into the fastening groove 321, the at least one fixing protrusion 331a can be arbitrarily fixed at a position where it is engaged with any one of the multiple fixing grooves 321a.

[0081] Meanwhile, the image portion 342 of the attention concentration member 340 may be composed of at least one of a picture, a photograph, or a three-dimensional model of a character or toy.

[0082] Of course, the image portion 342 may include the user's name alone or in addition to the name to enhance the user's identification.

[0083] At this time, the image portion 342 is manufactured using a lenticular printing technique to enhance the visual effect.

[0084] In conclusion, when an infant or child brushes their teeth by themselves or when a parent brushes their teeth, the toothbrush 300 of this embodiment can arouse the interest of the infant or child through the image unit 342 of the attention concentration member 340, making tooth brushing more fun and enjoyable.

[0085] In this case, when rotating the toothbrush 300 to brush the upper teeth and then the lower teeth, by rotating the rotation support member 330 with the detachable part 341 of the attention concentration member 340 fastened to the rotation support member 330, the image part 342 can be continuously positioned in the line of sight of the infant or child whose teeth are to be brushed.

[0086] Meanwhile, although not shown in detail, the toothbrush 300 of this embodiment may further include a light-emitting unit on the attention-focusing member 340 for emitting light to the outside.

[0087] Here, the light emitting unit may include an LED (Light Emitting Diode) accommodated inside the image part 342 of the attention concentration member 340 and a dry cell battery for supplying current to the LED, and the image part 342 may be made of a transparent material so that light emitted by the LED can be irradiated to the outside. In this case, the attention concentration member 340 may have a structure in which the image part 342 can be separated from the detachable part 341 to conveniently attach or replace the LED.

[0088] As a result, when an infant or child is brushing their teeth in a dark environment, the toothbrush 300 of this embodiment not only attracts more interest from the infant or child by emitting light to the outside using the light-emitting unit, but also allows the infant or child to brush their teeth more accurately.

[0089] On the other hand, as shown in Figures 8 and 9, in the toothbrush of this embodiment, instead of forming a coupling groove on the outer peripheral surface of the aforementioned rotating support member, a coupling groove 433a may be formed in the center of the end face 433 that contacts the outer peripheral surface 432 of the rotating support member 430, and therefore the detachable portion 441 of the attention concentration member 440 may consist of a coupling protrusion 441a that protrudes in a lateral direction that is approximately perpendicular to the longitudinal direction of the attention concentration member 440.

[0090] That is, in this embodiment, the coupling protrusion 441a forming the detachable part 441 can be inserted into the coupling groove 433a along the rotation axis direction of the rotation support member 430.

[0091] In this case, similar to the above-described embodiment, a step portion 433a-1 may be formed inside the coupling groove 433a, and a locking portion 441a-1 that is locked to the step portion 433a-1 may be formed on the coupling protrusion 441a.

[0092] In addition, the attention concentration member 440 of this embodiment may have the locking portion 441a-1 formed of an elastic rubber material or a soft resin material so that it can be separated from the rotation support member 430 in a replaceable manner.

[0093] Of course, instead of forming the locking portion 441a-1, the coupling protrusion 441a may be formed of an elastic rubber material or a flexible resin material, and configured so that the coupling protrusion 441a is inserted into or separated from the coupling groove 433a by a press-fit method.

[0094] On the other hand, although not shown in detail, instead of providing a rotating support member at the other end of the toothbrush handle, a coupling groove may be formed at the other end of the toothbrush handle, a coupling protrusion corresponding to the coupling groove may be formed on the detachable portion of the attention concentration member, and the coupling protrusion may be detachably coupled to the coupling groove, thereby allowing the attention concentration member to be detachably provided directly at the other end of the toothbrush handle.

[0095] Of course, a coupling groove may be formed in the detachable portion of the attention concentration member, and a coupling protrusion corresponding to the coupling groove may be formed on the other end of the toothbrush handle, so that the coupling protrusion can be detachably coupled to the coupling groove.

[0096] In either case, the coupling protrusion may be configured to rotate while inserted into the coupling groove, thereby allowing the attention concentration member to be rotated 360 degrees based on the toothbrush handle, and positioning the attention concentration member at eye level for the child while brushing their teeth.

[0097] FIG. 10 is a perspective view schematically showing a toothbrush according to still another embodiment.

[0098] Referring to FIG. 10, a toothbrush 500 according to another embodiment is disclosed in which a toothbrush handle 520 and a focus member 540 are configured to be coupled or separated by a press fit.

[0099] That is, the detachable portion 541 of the attention concentration member 540 can be attached or detached by a press-fit method while surrounding the end of the toothbrush handle 520 like a cap, and conversely, the end of the toothbrush handle 520 can be attached or detached by a press-fit method while wrapping the detachable portion 541 of the attention concentration member 540 like a cap.

[0100] The detachable part 541 of the attention concentration member 540 can be rotated while being press-fitted into the end of the toothbrush handle 520 .

[0101] Therefore, when rotating the toothbrush 500 according to the tooth brushing position, the detachable part 541 can be rotated to match the line of sight of the infant or child being brushed, thereby allowing the image part 542 extending from the detachable part 541 to be continuously positioned in the line of sight of the child being brushed.

[0103] This increases the bonding strength of the attention concentration member 540, and in particular, after the detachable part 541 of the attention concentration member 540 is rotated to a predetermined angle at the end of the toothbrush handle 540, the bonding strength of the protrusion and groove can firmly maintain the rotated state of the attention concentration member 540.

[0104] FIG. 11 is a perspective view schematically showing a toothbrush according to still another embodiment.

[0105] Referring to FIG. 11, a toothbrush 600 of this embodiment discloses a toothbrush handle 620 and an attention-focusing member 640 that can be connected or separated by a snap-in method.

[0106] That is, the lower end of the detachable part 641 of the attention concentration member 640 is bent and protruded to form an insertion protrusion 641a, and an insertion hole 620a may be formed at the end of the toothbrush handle 620 to which the insertion protrusion 641a is attached or detached in an insertion manner.

[0107] Therefore, the attention concentration member 640 can rotate around the fitting hole 620a while being fitted and coupled to the fitting hole 620a of the toothbrush handle 620 by the fitting protrusion 641a.

[0108] Therefore, when rotating the toothbrush 600 according to the tooth brushing position, the attention concentrating member 640 can be rotated to match the line of sight of the infant or child being brushed, thereby allowing the image part 642 extending from the detachable part 641 to be continuously positioned in the line of sight of the subject being brushed.

[0109] FIG. 12 is a perspective view schematically showing a toothbrush according to still another embodiment.

[0110] Referring to FIG. 12, the toothbrush 700 of this embodiment discloses a toothbrush handle 720 and an attention-focusing member 740 that are connected or separated in a snap-in manner, similar to the toothbrush 600 of FIG. 11 described above.

[0111] In detail, the toothbrush 700 of this embodiment has the same fitting method as the toothbrush 600 of Figure 11 described above, but the end of the toothbrush handle 720 may have a fitting protrusion 720a instead of a fitting hole, and the attachment / detachment part 741 of the attention concentration member 740 may have a fitting hole 741a to which the fitting protrusion 720a can be attached or detached in a fitting manner.

[0112] Thus, with the fitting protrusion 720a of the toothbrush handle 720 fitted into the fitting hole 741a of the attention concentration member 740, the attention concentration member 740 can rotate around the fitting hole 741a.

[0113] Therefore, when rotating the toothbrush 700 according to the tooth brushing position, the attention concentration member 740 can be rotated to match the line of sight of the infant or child being brushed, thereby allowing the image part 742 extending from the detachable part 741 to be continuously positioned in the line of sight of the subject being brushed.
