[0006] However, the conductive part on the grip side and the conductive part on the head side need to be in contact when the head is assembled to the grip, and in a separated state (non-contact state) when the head is removed from the grip, so both conductive parts are provided with contact points. Therefore, the structure of the conductive part becomes complicated, and there is a possibility that operation failure may occur due to poor contact of the contact points. Utility Model Content

[0007] Therefore, an object of the present disclosure is to provide a beauty instrument, in which the structure of the conductive part provided from the grip part to the head part is simple and good, and poor contact will not occur.

[0008] From one aspect, the utility model provides the following solution.

[0010] (2) In the structure of the above (1), the head portion is detachably mounted on the grip portion.

[0011] (3) In the configuration of (2) above, the electrode is press-fitted into the contact point portion of the conductive portion.

[0012] (4) In the structure of (2) above, the electrodes are of two types: positive electrodes and negative electrodes.

[0013] (5) In the structure of the above (2), it further includes a brush portion detachably mounted to the head portion.

[0014] (6) In the configuration of (5) above, the electrode is provided on a side of the head portion opposite to the brush portion.

[0015] (7) In the structure of the above (5), the brush part can be detached by being pressed into a brush pressing part of the head and being pulled out from the brush pressing part.

[0016] (8) In any one of the structures of (5) to (7) above, the head outputs electrical stimulation from the oral cavity so that the electrical stimulation can act on at least one of the orbicularis oris muscle, zygomaticus major muscle, zygomaticus minor muscle, smile muscle and buccinator muscle.

[0017] The effects of the utility model are as follows.

[0025] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

[0026] like Figures 1 to 5As shown, a toothbrush 1 as an example of a beauty instrument disclosed in the utility model includes: a grip 2 held by a user; and a head 3 equipped with electrodes 10, 11 and a brush part 12. The entire or most of the grip 2 is formed as a pairing electrode corresponding to the electrodes 10, 11 of the head 3. The grip 2 is equipped with a power switch (not shown) and the like for controlling the on and off of the power. A battery (not shown), an AC generator (not shown) and the like are installed in the grip 2. The battery can be charged regardless of contact or non-contact. The frequency of the AC generator can be any, as long as it is between 1Hz and 3000Hz, but it is preferably set in a suitable range for stimulating muscles, that is, between 1Hz and 300Hz or between 1000Hz and 3000Hz. The output current value of the AC generator is set within a range that ensures the safety of the galvanic current (Galvani current) passing through the oral cavity and the safety of the tongue electrical stimulation (GST).

[0027] A conductive portion 4 extending directly from the front end of the gripping portion 2 is protrudingly provided on the gripping portion 2. Two contact point portions 4a, 4b are provided on the front end side of the conductive portion 4 at the longitudinal displacement position of the conductive portion 4. The two contact point portions 4a, 4b and the base side (ground) of the conductive portion 4 are insulated from each other by two insulating portions 4c. Each contact point portion 4a, 4b protrudes in two directions orthogonal to the straight line shape of the conductive portion, and each protruding shape is a pressed blade shape with a pointed end. Each contact point portion is arranged in each electrode assembly groove 33 described below (see Figure 4 (a)).

[0028] The conductive portion 4 at the front end of the grip portion 2 is provided with a press-fit convex portion 2a (see Figure 2 ).

[0029] As described below, the head 3 is detachably arranged on the gripping portion 2. The head 3 has a conductive portion receiving hole 31 extending longitudinally therein (see Figure 3 The conductive portion receiving hole 31 is opened on the assembly side of the grip portion 2. The head portion 3 is assembled to the grip portion 2 by pressing the press-in protrusion 2a of the grip portion 2 into the conductive portion receiving hole 31, and the detachable setting is achieved by a structure that allows the press-in protrusion 2a to be pulled out from the conductive portion receiving hole 31.

[0030] The conductive portion receiving hole 31 is connected to each electrode mounting groove 33 described below at the front end side of the head 3. The front end side of the head 3 is provided with a partition portion 32 (see FIG. Figure 5 ) is bounded by two electrode assembly grooves 33 (see Figure 4 (a)), and the other side is provided with a brush pressing groove 34 as a brush pressing portion (see Figure 5 ).

[0031] The two electrodes 10 and 11 are respectively assembled in the electrode assembly grooves 33 of the head 3 by insertion. During the insertion process, the two electrodes 10 and 11 are pressed into the contact points 4a and 4b of the conductive part 4. Accordingly, the electrodes 10 and 11 are respectively electrically connected to the contact points 4a and 4b of the conductive part 4. Of the two electrodes 10 and 11, one is a positive electrode 10 and the other is a negative electrode 11. The electrodes 10 and 11 are preferably made of titanium material, stainless steel material, conductive silicon, conductive rubber or metal plating.

[0032] The surface side of each electrode 10, 11 is from the electrode mounting groove 33 (see Figure 4 The surface side of each electrode 10, 11 protrudes the most at the center of the width direction of the head 3, and forms an arc-shaped curved surface relative to the width direction of the head 3 (see Figure 4 (a)).

[0033] The brush portion 12 has: a base 12a (see Figure 2 ); and raised bristles 12b erected from the base 12a. The brush portion 12 is detachably mounted in the brush pressing groove 34 of the head portion 3. The base 12a of the brush portion 12 is pressed into the brush pressing groove 34, and can be pulled out by applying an external force in the opposite direction of the pressing direction to the brush portion 12 installed in the brush pressing groove 34.

[0034] The brush part 12 and the two electrodes 10 and 11 thus mounted on the head 3 are located on opposite sides of the head 3. In addition, when the brush part 12 and the two electrodes 10 and 11 are mounted on the head 3, waterproofness is ensured so that water does not penetrate from the outside of the head 3 to the inside.

[0035] Next, a method of using the toothbrush 1 will be described. The user holds the grip 2 of the toothbrush 1 and turns on a power switch (not shown).

[0036] The front end of the head 3 is placed in the oral cavity to brush the teeth. At this time, the stains on the teeth can be removed by the friction between the brush part 12 and the teeth and the interference between the brush part 12 and foreign objects. On the other hand, the two electrodes 10 and 11 mainly move by touching the tongue and other parts when the brush part 12 is used to brush the inner side (inner side) of the teeth, and mainly press the skin in the oral cavity when the brush part 12 is used to brush the surface (outer side) of the teeth.

[0037] Here, when brushing teeth, saliva, tissue fluid and other liquids in the oral cavity will almost fill the area around each electrode 10, 11, so the positive electrode 10 and the negative electrode 11 and the grip 2 will be energized through the human body. Accordingly, the cheek muscles can be stimulated by ultrasound in the oral cavity, or the muscles can be contracted by EMS (electromyostimulation) in the oral cavity. In this way, facial muscles can be cared for while brushing teeth, and lifting and eliminating nasolabial folds can be expected. Since the distance to the cheek muscles is closer when current stimulation is given from the inside of the oral cavity compared to the EMS effect of applying alternating current stimulation from the front of the face, stronger muscle stimulation and higher EMS effect can be expected. In particular, it can be expected to have an effective stimulation effect on the orbicularis oris, the major buccal muscle, the minor buccal muscle, the risorius muscle, the buccinator muscle, etc. In addition, the cleaning effect induced by electrophoresis can be exerted to achieve oral cleaning.

[0038] Even when not brushing teeth, the toothbrush 1 can be inserted into the oral cavity to perform facial muscle care by massaging the skin, etc., through the same action as described above.

[0039] In addition, weakness of the muscles around the mouth can lead to sagging of the mouth, sagging of the corners of the mouth, nasolabial folds, and marionette lines. Since the mouth muscles are connected to a variety of expression muscles such as the buccinator, risorius, and buccinator muscles, exercise can not only affect the mouth but also the cheeks and lift them.

[0040] In this regard, according to the present embodiment, due to the above-mentioned effects, it is possible to promote the lifting of the cheeks and mouth, the lifting of the corners of the mouth (the effect of tightly lifting the corners of the mouth by tightening the mouth), the increase of blood flow (promoting blood circulation, expelling waste from hardened muscles, and improving swelling), and the enrichment of facial expressions (due to being connected to many expression muscles, the expressions are enriched), etc.

[0041] In addition, in the elderly population, the weakening or hardening of the muscles around the mouth can lead to a narrowing of the range of motion of the mandibular joint or tongue, resulting in reduced saliva secretion or decreased chewing power and swallowing function.

[0042] In this regard, according to this embodiment, due to the above-mentioned effects, it is possible to promote the effects of pronunciation improvement (clearer pronunciation), gum approximation (effect of applying microcurrent to the gums), blood flow increase (promoting blood circulation and relaxing hardened muscles), oral environment improvement (increasing saliva volume), etc. In addition, the improvement of the oral environment can also promote the prevention of tooth decay and periodontal disease, prevent bad breath, and improve swallowing function.

[0043] As described above, the toothbrush 1 includes: a grip 2 having a conductive portion 4 protruding from the front end; a head 3 detachably mounted on the grip 2 in a state where the conductive portion 4 is stored; electrodes 10, 11 mounted on the head 3 and electrically connected to contact points 4a, 4b provided on the conductive portion 4; and a brush portion 12 detachably mounted on the head 3. Thus, since there is no need to provide a contact point structure in the conductive portion 4 spanning from the grip 2 to the head 3, the structure of the conductive portion 4 becomes simple and good, and since there is no need to provide a contact point structure, there is no problem of poor contact. In addition, as a method of using the toothbrush 1, it is possible to select from a method of using only the brush portion 12, or a method of using the head 3 relative to the grip 2 and replacing the brush portion 12 and the electrodes 10, 11 according to each user.

[0044] Figure 4 (b) is a diagram showing electrodes 10 and 11 of a modified example. In the modified example, multiple protrusions 10a and 11a are arranged uniformly and without gaps on the surface of the electrodes 10 and 11. When brushing teeth, these multiple protrusions 10a and 11a contact the tongue surface, the skin in the oral cavity, etc. when moving, so bacteria can be effectively removed. In addition, since the stimulation of the cheek muscles can also be enhanced, it is also effective in lifting and removing nasolabial folds.

[0045] In addition, the electrodes 10 and 11 are preferably made of titanium or stainless steel. Furthermore, conductive silicone may also be preferably used as the electrode. Conductive silicone is a material that naturally generates silver nanoparticles by mixing silver sheets, fluororubber, fluorine surfactant, and organic solvent. The silver nanoparticles give it conductivity. Conductive silicone will not have any negative effects on the human body even if it is placed in the mouth, and because of its shrinkage, it feels good on the skin. In addition, conductive silicone has high physical stability and is not easy to deteriorate over time.

[0046] In the above embodiment, the head 3 is detachably mounted on the grip 2 by a structure capable of being pressed in and pulled out, but the head 3 may be detachably mounted by a structure other than being pressed in, and the detachable structure is not limited.

[0047] In the above embodiment, the brush portion 12 is detachably mounted in the brush pressing groove 34 of the head portion 3 by a structure capable of being pressed in and out, but it may also be detachably constructed by means other than pressing in, such as threaded fixing or twisting fixing, and its detachable structure is not limited.

[0048] The electrodes 10 and 11 are provided with a positive electrode 10 and a negative electrode 11, but the number of electrodes is not limited. In addition, the arrangement positions of the electrodes 10 and 11 are also not limited.

[0049] Although each embodiment has been described in detail above, the present invention is not limited to a specific embodiment, and various deformations and modifications can be made within the scope of the claims of the present invention. In addition, all or multiple components of the above embodiments can also be combined.

[0050] For example, in the above-mentioned embodiment, other forms of output parts without a brush function may be used instead of the brush part 12 .
