Description

  The present invention relates to an automatic advance / retreat toothbrush, and more particularly to an automatic advance / retreat toothbrush of a type in which bristles automatically advance and retract in the longitudinal direction.

  While research on the treatment of diseases such as gingivitis and periodontitis, preservation of teeth, prevention of dental diseases, etc., bath methods, flossing methods, methods combining them, massage methods by hands etc. are prosperous It has been studied and clinically tested. The Journal of Oral Hygiene Journal of Dental Health 47, 158-163 (1977) should be able to prevent and treat gingivitis and periodontitis by brushing. It is reported that it is said that it is due to two effects that brush bacteria can be removed by brushing, and that gingiva is mechanically massaged, keratinization of gingival epithelium is promoted, and gingival resistance is increased. Has been. In addition, the bath method is widely used as a brushing method for periodontal disease patients, but dental floss is used as an auxiliary brush for cleaning the interproximal portion where it is difficult to remove plaque. On the other hand, we developed an original brushing method called “toothpick method” and compared this with the bath method and flossing method in combination with the effect on periodontitis, especially the massage effect. Clinical and cytologically superior to the combined use of the method and flossing method. Such a point has been announced.

  In any case, brushing teeth is a task that is quite tiring because it is necessary to repeat the treatment for a long time each time. Above all, the “toothpick method” applies a wide brush surface to the teeth and presses the whole so that each of the hairs that make up the brush surface hits the tooth surface and pushes and bends between the teeth all at once. This is a difficult work requiring a strong force because the work to be performed is repeatedly performed by the piston motion.

On the other hand, an automatic advance / retreat toothbrush that advances and retracts in the longitudinal direction of the bristles using a brush or a bristles bundle is known (see, for example, Patent Documents 1 to 3). In such a toothbrush, the bristles automatically advance and retreat in the longitudinal direction, so that the bristle bundle enters well into the gingival sulcus around the roots of each tooth as well as between the teeth, and removes plaque and foreign substances over the details. Can be massaged and the "toothpick method" can be realized easily.

  However, in order to advance or retract the bristle bundle in the length direction, the bristle bundle is located in the direction that intersects it at the tip of the toothbrush, and also requires space for it to advance and retreat. There is no problem, but it is cramped and difficult to work by inserting the tip of the toothbrush between the tooth and the cheek with close contact with it and moving the bristles forward and backward in the length direction. Also, from the toothbrush side, a strong load is applied to the portion where the bristle bundle is advanced and retracted in the length direction, and if it does, the movement will weaken or stop and the effect will decrease, causing damage and failure.

  In view of this, it is conceivable to provide a guard on the back of the forward / backward portion of the bristle bundle to protect it from external forces due to the cheeks, and to ensure a space for the bristle bundle to advance / retreat even between the teeth and cheeks. However, this requires more space for the guard on the back of the bristle bundle advancing and retreating space, increasing the size of the toothbrush tip, making it difficult to insert between teeth and cheeks, Since the bristle bundle works on the teeth and gums while largely pushing the cheek away from the teeth by the guard, the work is still not easy.

  An object of the present invention is to provide an automatic advance / retreat toothbrush that secures advancement / retraction of the bristle bundle and is easy to work outside the teeth and gums.

  In order to achieve the above object, an automatic advance / retreat toothbrush of the present invention comprises a main body part and a bristle bundle oriented in a direction intersecting the axis of the main body part at a tip part extending from one end side of the main body part to the tip thereof. A swinging member that reciprocally swings to move the bristle bundle back and forth in its length direction, a driving means that reciprocally swings the swinging member by a drive source provided in the main body, and a back portion of the swinging member One feature is that a back guard for guarding the side from the other side is provided, and a window for retracting the tip side of the swing member is provided in the back guard.

  In such a configuration, the bristle bundle is driven to move back and forth in its own length direction by the swinging mechanism of the swinging member driving mechanism that holds the bristle bundle in the direction intersecting the axis at the tip of the main body. If you put the bristle bundle part at the tip of the main body part in the mouth and put it on the teeth, gums, interdental, periodontal groove, the hair tip advanced or retreated against them will repeatedly hit or enter, The so-called “toothpick method” can be automatically performed at high speed. Unlike the conventional method in which the brush surface is slowly pressed against the end in this case, a stimulating massage with a beat action according to the bundling form and its size is automatically performed at high speed, so the conventional The massage effect for one bristle bundle is higher than the method. Moreover, even when the bristle bundle is acted on the teeth and gums from the outside, the back guard located on the back of the rocking member protects the rocking member and the bristle bundle from pressure by the cheeks and ensures its forward and backward movement. This is realized by saving space by retracting the back guard on the front end side of the swinging member into the window when the bundle is retracted. However, the window is also effective as a recess that does not penetrate.

  The automatic advancing / retracting toothbrush of the present invention is detachably attached to the main body part and one end side of the main body part, and intersects the axis of the main body part at the tip part extending from one end side of the main body part to the tip thereof. A brush holder that supports a bristle bundle that faces the bristle bundle so as to advance and retreat in the length direction of the bristle bundle, and a rocking member that is oscillated by a drive source provided in the main body. A driving means that comes in contact with and disengages with attachment and detachment, and a back guard that extends from the brush holder to the back portion of the swinging member and guards the swinging member from the other side on the back side, are retracted from the tip side of the swinging member. Another feature is the provision of windows to enter.

  In such a configuration, in addition to the case of the one feature described above, the brush holder can be handled separately by removing it from the main body without interfering with the driving means.

In a further configuration, the bristle bundle is an advancing and retracting brush body that is mounted so as to be detachable from the swinging member.
Replacement due to deterioration or damage of the bristle bundle can be exchanged with the smallest advancing / retreating brush unit having only the bristle bundle.

  The drive means has a reciprocating / retreating portion facing one end of the main body, and a motion converting portion for converting the reciprocating movement of the reciprocating / retreating portion into the swinging of the swinging member between the reciprocating / retreating portion and the swinging member. It can be provided on the swinging member side, and a cam can be employed as the motion converting portion.

  A brush that is attached to one end of the main body so that the base can be attached and detached, can rotate around the axis intersecting the axis of the main body at the tip, and supports the rotating brush body so as to be reciprocated by a predetermined angle by the driving means. In a further configuration provided with a combination of holders, the brush holder provided with the rotating brush is replaced with a brush holder provided with a rocking member for advancing and retracting the bristles bundle, and the rotating brush is driven by attaching it to the main body. Can be used by reciprocating rotation.

    In this case, the drive means has a reciprocating / retreating portion facing one end of the main body, and a motion for converting the reciprocating motion of the reciprocating / retreating portion into the reciprocating rotation of the rotating brush body between the reciprocating / retreating portion and the rotating brush body. The conversion unit may be provided on the rotating brush body side.

  Further objects and features of the present invention will become apparent from the following detailed description and the accompanying drawings. Each feature of the present invention can be used alone or in combination in various combinations within a possible range.

  According to one aspect of the present invention, the bristles repeatedly abut against or enter the teeth, gums, interdental, and periodontal grooves as the bristles advance and retreat, and are stimulated by the brushing and beating action of the “toothpick method”. The automatic movement of the bristle bundle is ensured by the separation of the back of the rocking member and bristle bundle from the cheek by the back guard, while the bristle bundle moves backward in the back guard window at the tip of the rocking member. The space saving by retreating into can be avoided and problems such as enlargement and bulkiness of the tip of the toothbrush and a decrease in workability due thereto can be avoided.

  According to another feature of the present invention, in addition to the case according to one feature, the brush holder can be handled independently without the restriction of handling by the main body portion serving as the electric equipment portion, and the bristle bundle and the detail portion around the swing member can be handled. It can be washed and maintenance such as bristle bundle replacement can be easily performed.

  Hereinafter, an automatic advance / retreat toothbrush according to an embodiment of the present invention will be described in detail with reference to the drawings to provide an understanding of the present invention. However, the following description is a specific example of the present invention and does not limit the contents described in the claims.

  As shown in FIGS. 1 (a), 2 (a) and 2 (b), the present embodiment has a bristle bundle 1, a body portion 2, and a tip portion extending from one end side of the body portion 2 to the tip thereof. A swinging member 3 that supports the bristle bundle 1 in a direction intersecting with the axis 11 of the main body part, reciprocates and moves the bristle bundle 1 back and forth in its length direction, and a drive source provided in the main body part 2 4 is provided with a drive means 5 for reciprocally swinging the swinging member 3 and a back guard 6 for guarding the back side of the swinging member 3 from the other. A window 7 is provided that is shown by a solid line in (a), shown in phantom lines in FIG. 2 (b), shown in phantom lines in FIG. 1 (a), and retracted as shown by solid lines in FIG. 2 (b). Yes. As a result, the solid bundle shown in FIGS. 1 (a) and 2 (b) by the driving means 5 of the swinging member 3 that supports the bristle bundle 1 in the direction that intersects the axis 11 at the tip of the main body portion 2 and It is driven back and forth in the length direction of itself by swinging with the virtual line. As a result, when the portion of the bristle bundle 1 at the end of the main body 2 is held in the oral cavity and applied to the teeth, gums, interdental teeth, and periodontal grooves, the hair ends that are advanced and retracted with respect to them. Repeatedly hit or enter. This is a so-called “toothpick” method, which can be automatically performed at high speed.

  Unlike the conventional method in which the brush surface is slowly pressed against the end in this case, a stimulating massage with a beat action according to the bundling form and its size is automatically performed at high speed, so the conventional The massage effect by the bristle bundle 1 is higher than the method. Moreover, in order to allow the bristle bundle 1 to act on the teeth and gums from the outside, the back guard 6 positioned at the back of the rocking member 3 protects the rocking member 3 and the bristle bundle 1 from pressure by the cheeks and ensures their forward and backward movement. In addition, this can be realized by saving space by retreating the back guard 6 on the distal end side of the swinging member 3 into the window 7 when the bristle bundle 1 is retracted.

Therefore, the back guard on the back of the swinging member 3 and the bristle bundle 1 can automatically perform high-speed stimulating massage by the "toothpick method" by the advance and retreat of the bristle bundle 1 in the longitudinal direction and the beat action. 6 is secured by separation from the cheek, while the back movement of the bristle bundle 1 is reduced in space by retreating the back guard 6 on the distal end side of the swinging member 3 into the window 7, thereby increasing the size and bulk of the toothbrush tip. It is possible to avoid the problem that the workability is lowered due to the tension.
However, the window 7 is also effective as a recess that does not extend through.

  Here, it is unquestioned whether the body part 2 to the back guard 6 are integrated, or where the swing fulcrum 12 of the swing member 3 is provided from the body part 2 to the back guard 6. The type of the drive source 4 and the configuration of the drive means 5 using the drive source 4 are not particularly questioned. However, in the present embodiment, the drive source 4 can be driven by power supply from the secondary battery 14 built in the main body 2 using the electric motor 13, and a switch provided on a part of the trunk of the main body 2. The key 15 can be turned on and off. As a result, the switch key 15 can be gripped and handled by the main body 2 and operated with the thumb of the user's hand. The secondary battery 14 is charged at the other end of the main body 2 through the charging port 16. Such charging is performed, for example, by connecting the charging port 16 to the power feeding port 18 of the charging stand 17 as shown in FIG.

  In the present embodiment, it is divided into a resin body portion 2 and a resin brush holder 21 that can be attached to and detached from the resin body portion 2 so as to distribute and hold necessary equipment portions so that it is convenient for molding and maintenance. Yes. Specifically, since the brush holder 21 is a tip side member extending from one end of the main body 2 to the tip, the resin swing member 3 that supports the bristle bundle 1 serving as the tip side equipment member of the toothbrush. In addition, the back guard 6 is provided, and the main body 2 is provided with the secondary battery 14, the drive source 4, and the drive means 5 thereby or most of the drive means 5. For this purpose, the brush holder 21 is formed in a cylindrical shape so that the base portion can be attached and detached at a screw fitting portion 22 with one end side of the main body portion 2. The swinging member 3 is supported so as to be able to swing around the swinging fulcrum 12 so as to be separable from the driving means 5 and the tip of the swinging member 3 supporting the bristle bundle 1 is moved forward. It protrudes and can be inserted into the oral cavity, and the bristle bundle 1 is supported in a direction crossing the axis 11. Further, the back guard 6 protrudes integrally from the tip end portion of the brush holder 21 and is positioned on the back portion of the swinging member 3 so as to exert the guard action. Thereby, by removing the brush holder 21 from the main body 2, the bristle bundle 1 and the swinging member 3 can be handled by handling the brush holder 21 alone without the restriction of the presence of the main body 2 and its handling as an electric equipment. The details of the surroundings can be washed, and maintenance such as replacement of the bristle bundle 1 can be easily performed.

  The screw fitting portion 22 includes a male screw 22a provided on the outer periphery of the plug portion 2a on one end face of the main body 2 shown in FIG. 2A and a female screw provided on the inner periphery of the base of the brush holder 21 shown in FIG. 22b, and can be mounted and removed in a predetermined direction by a rotation of approximately 45 °. As shown in FIG. 2 (a), the driving means 5 has a reciprocating / retreating portion 31 facing one end side of the main body 2, specifically, the tip of the plug portion 2a. Can be separated from each other as the brush holder 21 is attached to and detached from the main body 2 and is related to each other by mounting. Are provided with a motion conversion part 32 on the side of the swinging member 3 for converting the forward / backward movement of the reciprocating forward / backward part 31 into swinging of the swinging member 3. As shown in FIG. 2 (b), the motion converting portion 32 having such a function has a simple configuration when the cam is inclined with respect to the advancing / retreating direction of the reciprocating / retreating portion 31, specifically, the direction of the axis 11. There is also an advantage that the operation can be transmitted reliably. However, the present invention is not limited to this, and various motion conversion methods can be employed. The motion converting portion 32 of the present embodiment is provided with the cam form as a part of the inner periphery of a trumpet-shaped base portion 3 a that receives the reciprocating advance / retreat portion 31. The part 31 keeps fitting with the trumpet-shaped base part 3a so as to work reliably on the motion converting part 32. Further, the motion converting portion 32 is driven to be brought into pressure contact with the reciprocating / retreating portion 31 simultaneously with the attachment of the brush holder 21 to the main body portion 2 by the bias of the spring 33 that is acted between the swing member 3 and the brush holder 21. I have to. The selection of the interlocking mechanism that allows the drive side and the driven side to be separated from each other using such a spring 33 is free.

  The drive means 5 is made of metal, and a frame-type cam follower 31a is integrally formed at the end in the main body portion 2 of the reciprocating advance / retreat portion 31 penetrating so that the front end side of the main body portion 2 can be reciprocated. The eccentric cam 35 connected via the bevel gear pair 34 is fitted, the electric motor 13 is turned on, and the eccentric cam 35 rotates, whereby the reciprocating / retreating portion 31 reciprocates and reciprocates the swinging member 3 via the motion converting portion 32. Repeatedly swing back and forth.

By the way, the bristle bundle 1 is worn, deteriorated or damaged by frequent brushing action or beat action. For this reason, it is necessary to replace it in a timely manner. In order to facilitate this, in the present embodiment, the bristle bundle 1 is implanted in a small block-like brush base 36 made of resin or the like as shown in FIG. The moving member 3 is detachably fitted in a support hole 3b provided on the surface facing the tooth at the tip of the moving member 3 so that it can be replaced as necessary. For such fitting, press fitting is sufficient. This is because the bristle bundle 1 is mainly subjected to a buckling load and receives almost no force in the pulling direction even when it enters between the teeth and returns, and is formed in a state where the brush stand 36 is connected in a predetermined number of units. In addition, it is easy to press-fitting by pushing the support hole 3b formed in accordance with the brush stand 36 by using the connected shreds that remain when planting and separating them one by one. can get. However, if necessary, an inadvertent detachment fitting structure such as screw alignment can be employed. In addition, as shown in FIG. 2 (f), such a detachment prevention fitting structure swings the support groove 3c in the form of a dovetail that narrows and opens toward the surface facing the teeth of the swing member 3. A brush base 36 formed in a state of being cut from the distal end side or side surface of the moving member 3 and fitted to the support groove 3c is slid and inserted from the mounting opening 3c1 opened on the distal end side or side surface. If it does so, it will be easy to prevent that the attachment / detachment direction through the attachment port 3c1 becomes a direction orthogonal to the advancing / retreating direction of the bristle bundle 1, and inadvertently dropping out during use. In particular, the mounting opening 3c1 of the support groove 3c prevents the brush base 36 from being inadvertently removed due to the frame portion 21a around the window 7 in the back guard 6 being in the immediate vicinity while the bristle bundle 1 is advanced or retracted. Since many timings for the state are obtained, the effect of preventing the brush stand 36 from falling off is further enhanced. In the example shown in FIGS. 2G and 2H, the support groove 3c has a C-shaped channel shape. If the brush base 36 is press-fitted from the distal end side of the swinging member 3, the support groove 3c is wrapped by both side flanges 3c2. It becomes harder to come off. In relation to this, the rear end wall of the support groove 3c of the swing member 3 is provided with a removal hole 3d for facilitating removal by pushing out the bristle bundle 1 from behind with a toothpick or the like. A rotating brush body 42 is attached to one end side of 2 so as to be detachable, can be rotated around an axis 41 intersecting the axis 11 of the main body 2 at the tip, and is reciprocated by a predetermined angle by the driving means 5. The brush holder 43 supporting the above is provided in combination. Thus, the brush holder 43 provided with the rotating brush body 42 is attached to the main body 2 as shown in FIG. 1B instead of the brush holder 21 provided with the swinging member 3 for moving the bristle bundle 1 forward and backward. The rotating brush body 42 in which the necessary number of bristle bundles 1 are implanted can be used by being reciprocally rotated by the driving means 5. As a result, it is possible to perform the cleaning by rotating the rotary brush body 42 in a reciprocating manner using the main body 2 as needed.

  Corresponding to having the reciprocating advance / retreat portion 31 facing the one end side of the main body 2 described above, the driving means 5 is provided between the reciprocating advance / retreat portion 31 and the rotating brush body 42. It is assumed that a motion conversion unit 44 for converting the advance / retreat operation into the reciprocating rotation of the rotating brush body 42 is provided on the rotating brush body 42 side. As shown in FIGS. 2C and 2D, the motion converting portion 44 having such a function includes a passive portion 45a fitted in the advancing / retreating direction of the reciprocating advance / retreat portion 31, specifically, the direction of the axis 11 as a base. The tip of the link 45 is connected to a crankpin 47 linked to the rotating brush body 42, and the crankpin 47 is provided on a rotating plate 46 directly connected to the rotating brush body 42. The passive portion 45a is formed in a trumpet shape so that when the brush holder 43 is attached to the main body portion 2, the reciprocating advance / retreat portion 31 keeps fitting with the trumpet-shaped passive portion 45a and works reliably. It is. Further, the motion converting portion 44 is driven to be brought into pressure contact with the reciprocating advance / retreat portion 31 simultaneously with the attachment of the brush holder 43 to the main body portion 2 by the bias of the spring 147 operated between the link 45 and the brush holder 43. Yes. The selection of the interlocking mechanism that allows the drive side and the driven side to be separated from each other using such a spring 147 is free.

  As shown in FIG. 3, the charging stand 17 has brush holder storage portions 17 a and 17 b on the left and right sides of the power supply port 18, and the brush holders 21 and 43 removed from the main body portion 2 as shown in a slightly pulled-out state. It is accommodated individually and closed with lids 17c and 17d.

  Here, the bristle bundle 1 has a thickness of 0.1 to 0.2 mm in order to satisfy an appropriate buffering due to elastic buckling against the gums and periodontal pockets while securing a brushing action and a beat action. It is preferable that the bristles have a bundling shape with a diameter of approximately 1 to 3 mm in terms of a circle, and more preferably as a bunch of about 100 bristles having a thickness of 0.13 mm. Further, if the length of the bristle leg exceeds 11 mm even at 1 mm, the waist becomes too weak and the buffering action is reduced, so it is preferable that the length is less than 11 mm. In addition, the bristle bundle 1 has an advancing and retreating distance of about 4 to 6 mm, so that the beat effect is high, and subtle elasticity and waist strength that do not cause excessive stimulation can be obtained.

  In addition, in the case of a hair leg length of 11 mm, setting the advancing / retreating stroke of the bristle bundle 1 to about 4 mm is preferable because there is no excessive stimulation while realizing the scouring effect and the beat effect. However, even if the advancing / retreating stroke is about 3 mm and the stimulation is further reduced, the scouring effect and the beat effect can be obtained, and even if the squeezing effect and the beat effect are further enhanced by increasing the stroke to about 6 mm, the stimulation can withstand therapeutically. Fits in. Therefore, it is useful for adults with classification.

  The bristle bundle 1 employs a material of nylon or polyester. According to this, it is suitable for obtaining a delicate elasticity and waist strength that have a high beat effect and do not cause excessive stimulation. However, it is not limited to this.

  The present invention can be applied to an automatic advance / retreat toothbrush and is easy to use without being bulky by ensuring the advancement / retraction of the bristles.
