Description

[Technical field]

[0001] The present disclosure relates to a toothbrush and a toothbrush set that are provided with an attention-focusing member that can generate interest in tooth brushing and can easily guide young children in their tooth brushing habits. [Background technology]

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

[0004] For this reason, most toothbrushes are simply designed with various decorations on the handle, but in toothbrushes with decorations like the above, 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 sees the decorations and starts brushing their teeth out of curiosity, they soon feel disgusted because they cannot see the decorations while brushing their teeth, which makes it difficult to brush their teeth faithfully.

[0005] Even when grasping the handle so that the ornament could be seen, the child had difficulty easily focusing on the ornament because he or she had to force their eyes to look down.

[0006] And when a parent brushes their child's teeth, the child must open their mouth as wide as possible so that the parent can see the inside of the molars, but over time the open mouth may close naturally, or the child may become bored while brushing their teeth and intentionally change the shape of the mouth to interrupt the brushing. Therefore, while the child is brushing their teeth, constant attention and motivation are required to maintain the proper mouth shape such as "A" or "B". However, decorations drawn or attached to the handle are difficult to use as a reminder during brushing.

[0007] In addition, the decorations attached to the handle cannot be replaced until the toothbrush reaches the end of its life, which causes a problem in that the interest-inducing effect of the decorations decreases over time.

[0008] Meanwhile, in the case of family members including infants or children, toothbrushes of family members are usually stored together in a toothbrush holder installed in a toilet hand washing basin or the like, and used. However, since the heads of most of the toothbrush bristles are located in the storage space of the toothbrush holder, when multiple toothbrushes are stored, there is a possibility 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 are provided with a detachable attention-focusing member that stimulates the curiosity of an infant and can be easily and continuously seen with the naked eye even during tooth brushing, and can induce the infant to develop good tooth brushing habits.

[0010] To provide a toothbrush and a toothbrush set capable of inducing a tooth brushing habit of a child continuously by periodically replacing attention-gathering members with various characters capable of arousing the interest of the child.

[0011] To provide a toothbrush and a toothbrush set which are easily identifiable, 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 concentration 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 provided on the mounting portion of the coupling member so as to be detachable 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, 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 a 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 attachment / detachment 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 on the inside of 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 may be formed at the detachable portion of the attention concentration member to detachably couple to the coupling groove, or a coupling groove may be formed at the detachable portion of the attention concentration member, and a coupling protrusion may be formed at the other end of the toothbrush handle to detachably couple to the coupling groove.

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

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

[0025] The toothbrush of the present embodiment may further include a light-emitting unit provided on the attention concentration 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 part having a plurality of toothbrush bristles; a toothbrush handle having one end connected to the toothbrush head; a connecting member having a support part having one end extending from the other end of the toothbrush handle in a direction toward the toothbrush head and fixed to the inside of the toothbrush handle, and an attachment part provided at the other end of the support part and fixed to the other end of the toothbrush handle; a toothbrush including a detachable part detachably provided on the attachment part of the connecting member via magnetic force and an image part extending from the detachable part and embodying a character; and a toothbrush holder provided on a wall or mirror in a space in which the toothbrush is used, and having the detachable part of the attention concentration member detachably provided on the attachment part of the connecting member via magnetic force. Effect of the Invention

[0027] The removable attention-focusing member has the advantage of stimulating the child's interest and naturally inducing the child to develop a tooth-brushing habit.

[0028] The removable member rises significantly above the tip of the toothbrush, is positioned at a child's eye level, and can be rotated 360 degrees, providing the advantage that the member can be easily viewed with the naked eye while the child is brushing their teeth.

[0029] Taking advantage of the feature that allows parents to see the corresponding parts with the naked eye while brushing their children's teeth, parents can role-play as the corresponding character with their child or have a virtual conversation with the child, stimulating their child's imagination and guiding them to make the appropriate 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 allows maximum identification of individual toothbrushes, and has the advantage that toothbrushes can be easily stored in the toothbrush holder without interfering with other toothbrushes when not in use, thereby improving hygiene.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] The toothbrush includes a toothbrush head including a toothbrush part having a plurality of toothbrush bristles, a toothbrush handle having one end connected to the toothbrush head, and an attention concentration 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 belong 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." In addition, when a certain component is said to "include" 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" may be used to describe various components as used herein, 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 showing a toothbrush according to one embodiment, FIG. 2 is a perspective view showing a separable connection structure between the toothbrush handle and toothbrush head of FIG. 1, FIG. 3 is a perspective view showing a state in which a child's gaze is focused on an attention concentration member, and FIG. 4 is a perspective view 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 having one end connected 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 on 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 may extend from the other end of the toothbrush handle 120 toward the toothbrush head 110 and may be fixed to 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 inside of the toothbrush head 110.

[0043] Therefore, when the toothbrush bristles 111a formed on the toothbrush part 111 of the toothbrush head 110 become worn due to repeated 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 may be detachably connected through magnetic force, and in this case, one of the two may be formed of a magnet and the other may be formed of a metal that is detachable 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 at least one of a picture, a photograph, and a three-dimensional model of a character or a toy.

[0047] Of course, the user's name may be written alone or in addition in the image portion 142 to enhance the 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 manufacturing the toothbrush head 110 and the toothbrush handle 120 separately and connecting them to each other by the support portion 131 of the connecting member 130. However, the present invention is not limited to this, and the toothbrush head and the toothbrush handle can be integrally injection molded, or at the same time, they can be more simply manufactured by plastic injection molding in a form in which a magnet is inserted into the end of the toothbrush handle instead of the connecting member during the integral injection molding.

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

[0051] At this time, referring further to FIG. 3, when rotating the toothbrush 100 to brush the upper teeth and then the lower teeth, if the detachable part 141 of the attention concentration member 140 is attached to the mounting part 132 of the connecting member 130 and the image part 142 of the attention concentration member 140 is rotated together, 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 the present embodiment may further include a light-emitting unit that irradiates light to the outside on the attention concentration member 140 .

[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 for supplying current to the LED, and in this case, 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 in order 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 arouses the infant or child's interest by emitting light to the outside through the light-emitting unit, but also enables the infant or child to brush their teeth accurately.

[0055] Meanwhile, referring to FIG. 4, the toothbrush 100 of the present embodiment may constitute one toothbrush set 10 including a toothbrush holder 200 provided on a wall or mirror of a space in which 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 in which the toothbrush 100 is used, and the attention concentration 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 is detachable 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 formed 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] In other words, when the mounting portion 132 of the connecting member 130 is formed of metal, the toothbrush holder 200 is formed 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, when the mounting portion 132 of the connecting member 130 is formed of metal and the detachable portion 141 of the attention concentration member 140 is formed of a magnet correspondingly, 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 fixed 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 the present embodiment, a structure in which the toothbrush 100 is fixed to the toothbrush holder 200 in a horizontal direction has been disclosed, but the present invention is not limited thereto, and a structure in which the toothbrush 100 is fixed to the toothbrush holder 200 in a vertical direction may also be applied.

[0064] That is, the area of ​​the mounting 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 vertically fix and separate the toothbrush 100 to the toothbrush holder 200, 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 applied 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, a separate 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 generally showing a toothbrush according to another embodiment, Figure 6 is a cross-sectional view generally 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 generally 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 having one end connected to the toothbrush head 310, a rotating support member 330 rotatably provided on 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 part 341 detachably provided on the rotating support member 330 and an image part 342 extending from the detachable part 341 and embodying a character.

[0069] Here, the rotating support member 330 may be formed in an approximately "┫" shaped cylinder having a fastening protrusion 331 that is inserted and fastened into a fastening groove 321 formed at the other end of the toothbrush handle 320, but is not limited to this, and 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 rotating support member 330.

[0070] The rotation support member 330 may have a coupling groove 332a formed on one side of an outer circumferential surface 332 exposed to the outside when inserted and fastened to the other end of the toothbrush handle 320, into which the detachable portion 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 on the inner side of 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 be formed of the locking portion 341a-1 made 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 soft resin material, and the coupling protrusion 341a may be configured to be inserted into or separated from the coupling groove 332a by a press-fitting method.

[0075] Also, although not shown in detail, a coupling protrusion may be formed on one side of the rotating 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 rotating 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 fixing or detaching the attention concentration member 340 to or from the rotating support member 330.

[0076] The rotation support member 330 may have a coupling groove 332a formed on one side of an outer circumferential surface 332 exposed to the outside when inserted and fastened to the other end of the toothbrush handle 320, into which the detachable portion 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 rotating 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 rotating support member 330 rotates and then elastically returned to its original position.

[0080] In the end, when the rotating support member 330 rotates around the longitudinal direction connecting the toothbrush head 310 and the toothbrush handle 320 as the 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 at least one of a picture, a photograph, and a three-dimensional model, such as a character or a toy.

[0082] Of course, the user's name may be written alone or in addition in the image portion 342 to enhance the 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 his / her teeth by himself / herself or when a parent brushes his / her teeth, the toothbrush 300 of this embodiment can arouse the interest of the infant or child through the image portion 342 of the attention concentration member 340, making tooth brushing more fun and interesting.

[0085] In this case, when rotating toothbrush 300 to brush the upper teeth and then the lower teeth, by rotating rotation support member 330 with detachable part 341 of attention concentration member 340 fastened to rotation support member 330, it is possible to position image part 342 continuously within the line of sight of the infant or child being brushed.

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

[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 for supplying current to the LED, and in this case, 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 in order 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 arouses the infant or child's interest by emitting light to the outside through the light-emitting unit, but also enables the infant or child to brush their teeth accurately.

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

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

[0091] At this time, similarly to the above-described embodiment, a step portion 433a-1 may be formed on the inner side of 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, in the present embodiment, the attention concentration member 440 may be formed of the locking portion 441a-1 made of an elastic rubber material or a soft resin material so that the attention concentration member 440 can be detached 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 soft resin material, and the coupling protrusion 441a may be configured to be inserted into or separated from the coupling groove 433a by a press-fitting 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 a detachable portion of the attention concentration member, and the coupling protrusion may be detachably coupled to the coupling groove, thereby detachably providing the attention concentration member directly on 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 height for the child while brushing their teeth.

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

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

[0099] That is, the detachable portion 541 of the attention concentration member 540 may be attached or detached by a press-fitting method while surrounding the end of the toothbrush handle 520 like a cap, and conversely, the end of the toothbrush handle 520 may be attached or detached by a press-fitting 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 rotate while being press-fitted and coupled to the end of the toothbrush handle 520 .

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

[0102] Although not shown in detail here, a plurality of spaced apart fixing grooves or fixing protrusions may be formed around the end of the toothbrush handle 520, and fixing protrusions or fixing grooves corresponding to the fixing grooves or fixing protrusions may be formed on the inner surface of the corresponding attachment / detachment part 541.

[0103] This increases the bonding strength of the attention concentration member 540, and in particular, after the attachment / detachment part 541 of the attention concentration member 540 is rotated to a predetermined angle at the end of the toothbrush handle 540, the rotating state of the attention concentration member 540 can be firmly maintained due to the bonding force between the protrusion and the groove.

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

[0105] Referring to FIG. 11, a toothbrush 600 of this embodiment discloses a toothbrush handle 620 and a focus member 640 that can be combined or separated in a snap-on manner.

[0106] That is, the lower end of the detachable part 641 of the attention concentration member 640 is configured in a bent and protruding shape 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 connected or separated 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 toothbrush 600 according to the tooth brushing position, attention focusing member 640 can be rotated to match the gaze of the infant or child whose teeth are to be brushed, so that image portion 642 extending from detachable portion 641 can be continuously positioned in the gaze of the subject whose teeth are to be brushed.

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

[0110] Referring to FIG. 12, the toothbrush 700 of this embodiment discloses a toothbrush handle 720 and a focus member 740 that are connected or separated by a snap-on method, similar to the toothbrush 600 of FIG. 11 described above.

[0111] In detail, the toothbrush 700 of this embodiment has a similar fitting method to the toothbrush 600 of FIG. 11 described above, but the end of the toothbrush handle 720 may be formed with a fitting protrusion 720a instead of a fitting hole, and the attachment / detachment portion 741 of the attention concentration member 740 may be formed with a fitting hole 741a to which the fitting protrusion 720a is attached or detached by a fitting method.

[0112] Thus, with the fitting protrusion 720a of the toothbrush handle 720 fitted and coupled to 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 toothbrush 700 according to the tooth-brushing position, attention focusing member 740 can be rotated to match the gaze of the infant or child whose teeth are to be brushed, so that image portion 742 extending from detachable portion 741 can be continuously positioned in the gaze of the subject whose teeth are to be brushed.

[0114] Although the embodiments have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the following claims also fall within the scope of the present invention.
