Description

Toothbrush with enhanced cleaning {TOOTHBRUSH WITH ENHANCED CLEANING}

TECHNICAL FIELD The present invention relates to a powered toothbrush, and more particularly, to a toothbrush having a head with two unique moving parts that provide oral dryness benefits to a user.

Toothbrushes offer numerous oral hygiene benefits. For example, toothbrushes remove plaque and food debris, thus avoiding tooth wear and disease.

The powered toothbrush can be used several times. Electric toothbrushes have the advantage of giving movement to the bristles at a much faster rate than manual operation compared to manual (non-electric) toothbrushes. These powered toothbrushes give different movements and different directions of movement. This exercise, which is typically combined with manual movement of the toothbrush by the user, provides a significantly better cleaning force than manual toothbrushes. Typically, powered toothbrushes are powered by disposable batteries or rechargeable batteries that power the electric motor that drives the toothbrush head.

Known powered toothbrushes include a brush head with bristle carrier portions that rotate, swing or vibrate in various ways to clean the teeth. The bristles, typically including bristle tufts, are formed uniformly at one end fixed to the bristle carrier portion and freely contact the tooth surface during brushing at the other end. The free ends of the various tufts provide a surface enclosure that can be slightly deformed when the bristles are bent. When in contact with the surface to be brushed, the bristles deform so that the surface envelope coincides with the complex tooth surface. Generally, the teeth of the human body form a “C” shape in the upper and lower jaws, and each row of teeth has a convex outer curve and a concave inner curve. Each tooth has a very complex surface and has flat, concave or convex areas. The finer the match between the bristles and the tooth surface, the more effective the cleaning, whitening and / or irritation is.

Known powered toothbrushes generally align the bristles in a compact conical or cylindrical pattern on a circular disk bristle carrier. The powered toothbrush heads typically have a compact oval shape and are produced in a flat trimmed bristle pattern. Optionally, other head shapes and bristle patterns can also be used.

Another embodiment of a powered toothbrush is disclosed in US Pat. No. 5,525.916, which is incorporated herein by reference and patented to Macdowgirl. The toothbrush disclosed in this patent has a disc shaped bristle carrier. The bristle carrier and bristle are oscillating or oscillating. This type of toothbrush will be described with reference to FIGS. 1A-1C. The toothbrush 5 includes a handle portion 10 at the central end of the toothbrush 5 and a head 11 at the distal end of the toothbrush 5. The handle portion 10 includes a partition wall for accommodating the electric motor 14 and the batteries 15 and 16. The head 11 generally comprises a circular bristle holder (carrier) 13. The rotatable shaft 12 extends from the motor 14 to the head 11. The shaft coupling 17 is arranged along the shaft 12 and takes the form of the shaft 12 being separated at the point between the motor 14 and the head 11. Thereby, the shaft can be removed from the toothbrush 5, for example for cleaning, repair or replacement.

The head 11 includes a post 18 that provides a pivoting axis of rotation for the bristle holder 13 in which the bristle tufts 19 are embedded. The distal end of the shaft 12 has a journal or offset portion 20 which is radially displaced from the longitudinal axis of the shaft 12 integrally formed therewith. The bristle holder 13 includes a slot 22 for receiving the offset portion 20. The offset 20 and slot 22 take the form of being able to be oriented towards the insertion axis of the shaft 12 and the longitudinal axis of the post 18. When the motor 14 rotates the shaft 12, the movement of the offset portion 20 forms a circle around the axis 12 of the shaft 12, with the bristle holder 13 through the angle of rotation A to post 18. Is operatively coupled with the slot 22 to vibrate or oscillate about the axis of the axis. The rotation angle A is defined by the displacement of the offset portion 20 from the axis of the shaft 12 with respect to the diameter of the bristle holder 13.

Although powered toothbrushes as described above offer advantages over manual toothbrushes, such powered toothbrushes are subject to various limitations. Rotating or rocking the bristle holder (carrier) generally results in a rectangular or elliptical toothbrush head limiting the size of the movable bristle holder, thereby limiting the area of the bristles required for tooth cleaning. Further, when the bristles are arranged to contact the teeth during brushing, the bristles in contact with adjacent areas such as the gums become less. Thus, this compact bristle pattern provides cleaning while minimizing whitening and irritation.

Attempts to overcome the limitations associated with small powered bristles are disclosed in US Pat. No. 6.000.083 to Blochstein et al. The toothbrush disclosed in US Pat. No. 6.000.083 has a bristle area and pattern similar to a manual toothbrush, but the area of the bristle can be easily replaced with a powered bristle portion. As a result, the head has a powered or movable bristle and a stationary bristle portion. U.S. Patent No. 6.000.083 has the limitation that the stationary bristles are not as good at cleaning, whitening or irritation as compared to manual toothbrushes.

The International Bureau of Patent Application PCT / EP01 / 07615 to Blauman Gembeha discloses a powered toothbrush with two separate bristle sections that are movable. Each bristle portion may have a different range and / or shape of movement. However, only one bristle portion is powered. Another non-driven bristle portion is moved due to the resonance effect imparted by the moving frequency of the first bristle portion.

This free resonance is very difficult. Firstly, because the contact between the bristle portions slows or cancels the resonance of the non-electric gingham portion, the non-electric bristle portion is "floated" away from the powered bristle portion. This requires a gap or gap between them. This gap exposes the inner workings of the head to external debris such as water, saliva, toothpaste, and particulates. These foreign debris will interfere with the operation of the non-driven bristle head. For example, the non-electric bristle portion is subjected to an elastic load to assist its resonance. The foreign matter may accumulate around or in the spring and interfere with the function of the spring. In addition, since food may be present in the head, it may act as a host or host a potentially harmful but undesirable microorganism when induced directly into the oral cavity.

Another constraint of this design is that when the powered portion is moved from the resonant frequency, the non-powered bristle portion may be weakened or reduced by contact with the tooth. This can be caused by the pressure exerted on the powered bristles by the teeth or gums during brushing. Finally, the energy imparted by the non-driven bristles portion is only part of the energy input to the powered portion. Thus, the non-driven bristle portion has less cleaning effect than the powered portion, thereby limiting the efficiency of the overall toothbrush.

Accordingly, there is a need in the art for high-efficiency powered toothbrushes that can increase efficiency through a wider range of powered or driven bristles or otherwise movable bristles. There is also a demand for toothbrushes with increased whitening and / or stimulating effects over known toothbrushes. Along with this, there is a need for an improved toothbrush in which manufacturing and purchasing costs can be comparable to known electric toothbrushes.

Other features and advantages of the invention will be apparent from the foregoing description with reference to the accompanying drawings.

Thus, the present invention encompasses an apparatus employing various steps, one or more relationships of these steps to other steps, and a combination and configuration of components and elements used to carry out these steps; The scope of the present invention will be disclosed in the claims as disclosed in the following detailed description.

In order to fully understand the present invention, it will be described with reference to the accompanying drawings.

2, an exemplary powered toothbrush according to the first embodiment is shown at 100. In FIG. The toothbrush 100 has a handle 102 that forms an inner partition (not shown) for receiving various toothbrush components at its central end and a neck 106 that terminates at the head 120 at the distal end of the toothbrush 100. It comprises a brush portion 104 formed by. The handle 102 includes a free central end 108 and an opposite end 110. The neck 106 extends from the first end 112 to the second end 114, the first end 112 being disposed at the end 110 of the handle 102, and the second end 114. Is disposed on the head 120. In other words, the neck 106 is part of the toothbrush 100 extending between the handle 102 and the head 120. The neck 106 forms an inner partition (not shown) for receiving various actuating components of the toothbrush 100. The head 120 is generally aligned with the longitudinal axis of the toothbrush 100.

According to one embodiment, the neck 106 and the handle 102 are composed of an integral member by forming the neck 106 integrally with the handle 102 at the end 110 of the handle 102. In another embodiment, the neck 106 may be detachable from the handle 102 at the end 110. According to this detachable embodiment, the combined neck 106 and head 120 are adapted to exchange, service, and clean the handle 1012 or the combined neck 106 and head 120 (brush portion 104). To allow, it can be removed from the handle 102. In addition, the brush portion 104 may be detachably connected to the handle 102 in a position along the toothbrush. Those skilled in the art will recognize that various methods may be used to achieve this, for example, frictional insertion, helical connection, interlocking or bayonet insertion. For example, when the neck 106 is formed to be detachable from the handle 102, the first neck end 112 may have a connector link (not shown) that is removably connected to the handle 102 using conventional techniques. Include. It will be appreciated that the desorption point may be between the head 120 and the neck 106 such that the head 120 may have a refill head shape.

In addition, the shapes of the handle 102, the neck 106 and the brush 104 are merely exemplary; Handle 102 and neck 106 and / or brush 104 may be formed in a variety of forms. The shape of the handle 102, the brush 104 and the neck 106 can be formed in an aesthetic and / or ergonomic design so that the toothbrush 100 can be easily and comfortably gripped and operated by the user. The handle 102 includes slightly concave fingers 118a and 1178b formed on opposite sides of the handle 102. The concave finger portion 118a is generally formed to receive the thumb of the hand, while the remaining finger portion 118b is formed to accommodate one or more other fingers of the same hand, so that the toothbrush 100 is held by the user in the user's hand. Helps ensure proper gripping and safe gripping. One or more concave fingers 118 may include ribs or other rough surfaces to assist gripping by the user. Such surfaces with acceptable frictional properties, such as, for example, rubber, are generally known in the art.

Toothbrushes according to various embodiments to be described may be made from a number of materials suitable for use in oral care products. For example, the numerous components included in the toothbrush 100 are preferably formed of a plastic material. Thus, the handle 102, the brush portion 104 and / or the head 120 are molded from polyolefins such as polypropylene and polyethylene, polyamides such as nylon, and polyesters such as polyethylene terephthalate. Other suitable materials include polymethylmethacrylate, styrene acroylnitrate and cellulose esters such as cellulose propionate, natural rubber, and synthetic rubber and other materials known in the art.

3 to 5 show another embodiment of a powered toothbrush brush. The head 120 of the toothbrush 100 includes a head base 160 that at least partially forms the inner partition wall 121. The head base 160 is formed such that the distal end of the toothbrush 100 is generally rounded for comfort of the user while brushing.

The head 120 includes a first movable bristle carrier 180, which carrier is disposed at or near the outermost end of the head 120 as shown. Optionally, the first bristle carrier 180 may be disposed at any position on the head 120.

The first bristle carrier 180 is preferably formed to be able to rotate at least partially around the axis. In this embodiment, the first bristle carrier 180 moves in an oscillating or oscillating rotational manner. For example, the first bristle carrier 180 has the same or similar configuration as the bristle holder 13 shown in FIGS. 1A-1C. In this embodiment, the first movable bristle carrier 180 is a circular disk. The first movable bristle carrier 180 is not limited to a disc shape, and may have, for example, an elliptical, regular or irregular shape as long as the first bristle carrier 180 oscillates rotationally or vibratingly. . The circular disk shape is preferable because the circular disk shape requires the smallest gap amount for accommodating rocking motion.

The plurality of tooth protection elements 152 extend outwardly from the first movable bristle carrier 180 in a direction perpendicular to the plane formed by the surface of the first movable bristle carrier 180. The "teeth protection element" is a structure suitable for providing oral health benefits (e.g., tooth cleaning, tooth polishing, tooth whitening, etc.) by the form commonly used or by direct contact with the tooth surface and the surrounding area. Include form. Such tooth protection devices include tufts of bristles that can be formed to have many different shapes and sizes, and / or various elastomeric members (FIG. 17) that can be formed to have many different shapes and sizes, or combinations thereof. However, it is not limited to this. While bristle tufts aligned on the first bristle carrier 180 take only one exemplary form, it should be appreciated that other bristle forms (eg, staples, IMT, etc.) may also be used. The bristle tufts can all be formed of the same or different bristle materials (nylon bristle, spiral bristle, rubber bristle, etc.). In addition, the tooth protector may generally be aligned to be perpendicular to the surface of the first bristle carrier 180 (as described above), and some or all of the tooth protector may be aligned with respect to the first bristle carrier 180 as needed. Can be inclined at various angles. When the first bristle carrier 180 comprises a bristle tuft, it is particularly intended, as it forms a lot of motion from the moving tuft head to provide additional oral health benefits such as cleaning, teeth polishing and / or teeth whitening, etc. To achieve one result, a combination of bristle form, bristle length, bristle material and bristle direction can be selected.

The first bristle carrier 180 is limited to a movable bristle carrier 180, but the first movable bristle carrier 180 is not limited to having only a bristle tuft as part thereof. Instead, the first movable carrier 180 is broadly considered to be a carrier for various combinations of the appropriate number of dental guards 152 or different types of dental guards 152. For example, the first movable carrier 180 may include a plurality of elastomeric members to provide the desired oral health benefits. The elastomeric member is attached to the first movable carrier 180 using conventional techniques, that is, by forming the elastomeric member integrally with the top surface of the carrier 180. Accordingly, the tooth protection element 152 provided as part of the first movable carrier 180 may be formed in one form (eg, bristle tufts or elastomeric members) or in a mixed state.

For example, the first bristle carrier 180 includes a plurality of first bristles extending outward from the first bristle carrier 180 as the tooth protection element 152. The term "brush head" or "brush heads" may be in a form suitable for providing oral health benefits (e.g., tooth cleaning, tooth polishing, tooth whitening, massage, irritation, etc.) during contact with teeth and gum surfaces. Include a structure. Since the bristles have a degree of curvature that can be bent during brushing, the bristles can be matched to the shape and surface of the teeth and gums, thereby increasing the bristle contact with the teeth and gums to improve efficiency.

The bristles can be composed of a variety of materials, including non-elastomeric or elastomeric materials. The term "elastomer" refers to a material that is very stretchable under tensile or stress, and the term "non-elastomer" refers to a material that is relatively stretchable under tensile or stress. Suitable examples of non-elastomeric materials generally include, but are not limited to, polyamides such as nylon or polyesters such as polybutylene terephthalate. In general, suitable examples of elastomeric materials include block copolymers such as rubber (synthetic or natural) and styrene (eg styrene ethylene butadiene styrene or styrene butadiene styrene), polyolefins (eg polypropylene 'ethylene propylene diamine modifications). Systems (ie synthetic rubbers)], polyamides [eg polyamides (2 or polyamides 6)], polyesters (eg polyester esters or polyether esters), polyurethanes (eg Polyesterurethane, polyetherurethane or polyesteretherurethane), but is not limited thereto. In non-elastomeric or elastomeric bristles, these materials are preferably formed in such a way that they become non-plastic and can be returned to their original shape and size after the force of brushing is removed.

The non-elastomeric bristles are connected to the head 120, for example to the first bristle carrier 180 in the form of a tuft. The bristles and / or tufts are connected to the head 120 by various means such as stapling and IMT during manufacture or by other known means. Elastomeric bristles are manufactured by known processes such as molding and the like and are connected to the head by known means.

As shown, the tooth protection element 152 has a particular size, shape, amount, length, form, material and / or combination thereof, which is merely exemplary; The tooth protection element, for example bristles, can take any form, amount, length, form, substance, and / or combination thereof that is oral hygiene suitable to achieve a particular result or the operating characteristics of the bristles. Must be aware of For example, the bristles can have different (non-uniform) lengths to form specific surface envelopes to improve efficiency. For example, the first movable carrier 180 may include bristle tufts having a first height as well as bristle tufts having different heights. This is done to accommodate differences between toothbrush users, including oral size, tooth shape and shape, tooth and gum sensitivity, eating and other oral behaviors (eg, smoking), and personal preferences.

One desirable property of such elastomeric tooth protector 152 is its ability to be manufactured in a variety of shapes. 13-17 illustrate various exemplary elastomeric members that can be used as the tooth protection element 152. Fig. 13 shows the elastomeric tooth protection element in the form of a thin spike, Fig. 14 shows the elastomeric tooth protection element in the form of a barrel spike, and Fig. 15 shows the elastomeric tooth protection element in the form of a rubber mop. Shows an elastomeric tooth protector in the form of an angle point, and FIG. 17 shows an elastomeric tooth protector in the form of an elastomeric wall portion. The elastomeric wall of Figure 17 may be formed in a linear, flat, zigzag, serpentine shape, or the like. In one embodiment, the elastomeric tooth protector, for example bristles, may be formed to have a soft texture, or may have a rough surface. Further, the wall portion of the elastomeric protective element is formed in a straight line in the vertical direction; One end may be formed to be inclined inward, or may be formed to extend toward one end. The upper portion of the elastomeric tooth protection wall may be formed in the form of a flat surface or a protrusion. While the foregoing describes various forms of elastomeric bristles as part thereof, one skilled in the art will recognize that any form of vertical may be possible.

Although the first movable carrier 180 is shown to include a set number of bristle tufts, the first movable carrier 180 may be formed completely or partially of an elastomeric member.

The first movable bristle carrier 180 is configured to be pivotally rotatable about its center point, such that the surface is disposed perpendicularly to or from the first movable bristle carrier 180 or in the direction of rotation of the first movable bristle carrier 180. Movement of the bristle tufts and / or elastomeric members extending outwardly from the plane defined by < RTI ID = 0.0 > The motion of the first movable bristle carrier 180 is a rocking motion when the first movable bristle carrier 180 is pivoted around the post at its center point (see FIG. 1). The first movable bristle carrier 180 is formed with a slot or opening (not shown). This slot is the same as or similar to slot 22 of FIGS. 1A-1C. The slot 22 is formed at a peripheral edge of the first movable bristle carrier 180 and extends along a substantial height of the first movable bristle carrier 180. For example, the slot 22 does not extend to the upper surface of the first movable bristle carrier 180 in which the tooth protection element is formed. Instead, the slot 22 has a closed top that prevents foreign debris, such as saliva, toothpaste, foreign particles, etc. from entering the slot 22 when the operator brushes. Opposite ends of the slots 22 disposed in the inner partition of the head 120 may be open.

The toothbrush 100 comprises a drive mechanism for performing the movement of the various parts of the toothbrush 100, in particular for the movement of at least the first movable bristle carrier 180. Suitable drive mechanisms are disclosed in U. S. Patent No. 5.525.916, incorporated herein by reference and patented by Macdowgirl, which drive mechanism extends through at least the neck 106 (ie, its inner bulkhead). The drive shaft 200 is included. As mentioned above, such a mechanism is used to impart motion to the first bristle carrier. However, one of ordinary skill in the art will recognize that the illustrated apparatus may be modified in various ways as long as it can perform the intended function. The drive shaft 200 is configured the same as or similar to the drive shaft 12 shown in Figs. 1A to 1C.

The drive shaft 200 has one end (not shown) operably connected to a drive member (not shown) in the form of all or other drive mechanisms to impart motion to the first movable bristle carrier 180. The drive shaft 200 includes opposite ends (not shown) that are bent such that the ends are not axially aligned with the longitudinal axis of the drive shaft 200. The distal end may be formed in a shape similar to that of the end 20 of FIGS. 1A to 1C, or may be formed in another shape as long as the intended function can be performed. In other words, the end is an overlapping crank end of the drive shaft 200 and is formed to be received in the slot 22; The 360 ° rotational movement of the shaft 200 is transmitted to the rocking and forward and backward rotational motion of the first movable bristle carrier 180.

The drive mechanism of the electric toothbrush 100 can, for example, perform rotational drive, oscillation drive, eccentric drive, non-equilibrium drive, drive with one or more gear mechanisms, or any other form of implementation of the intended function. It is a drive mechanism. The drive mechanism may be realized as an electric motor or other type of motor, and the motion generated by the drive is imparted to one or more portions of the head 120 or other elements disposed in the brush portion 104. The exercise is given directly or indirectly. Those skilled in the art will recognize many suitable apparatus. The motion may be imparted directly through a drive shaft, such as the drive shaft 200, or through a drive post attached to the drive shaft. When the toothbrush 100 includes a swinging drive mechanism that is the same or similar to the example drive mechanism shown in FIGS. 1A-1C, the inner partition of the handle 102 includes a motor operably connected to the drive shaft 200, and It houses a drive source that drives the motor as one or more batteries.

When the drive mechanism is actuated and the drive shaft 200 rotates, the movement of the crank end is at an angle of about 10 ° to about 120 °, preferably at an angle of about 10 ° to about 30 °, most preferably about 10 At an angle of between about 15 degrees and about 15 degrees, the oscillating back and forth motion of the first movable bristle carrier 180 is imparted.

In FIG. 3, the toothbrush 100 further includes a second movable bristle carrier 210 operatively connected to the head 120. The second movable bristle carrier 210 is formed of an elastomeric material and is generally formed in the form of a head portion having a range of motion when a force is applied during normal brushing and / or during normal use of the toothbrush 100. The elastomeric second bristle carrier 210 has a first end disposed in close contact with the first bristle carrier 180 and an opposing second end disposed at or near the central end of the head 120. 214). The elastomeric second bristle carrier 210 has a first side 216 having a recess 220 formed between the first and second ends 212 and 214 and the first and second sides 218 and 220. And a second side 218. The recess 220 forms a concave partition wall having a floor 222.

According to one embodiment, the elastomeric second bristle carrier 210 is supported only at the first side 216 and the second side 218 by the head base 160; The malleable elastomeric second bristle carrier 210 extends across the inner septum 121 of the head 120 and is formed of a substantially “floating” elastomeric platform. Attachment of the elastomeric second bristle carrier 210 to the head base 160 may be accomplished using conventional techniques such as using an adhesive or integrally attaching two members during mechanical bonding or molding. In one embodiment, sidewalls of the head base 160 are formed with cutouts (ie, U-shaped in the illustrated embodiment) that receive the first and second sides 216, 218, which are detailed in FIG. 4. As shown, it is formed as a sidewall received in the cutout of the head base 160.

Since the first bristle carrier 180 is formed in the shape of a disc, the first end 212 is formed in an arcuate shape to accommodate the oscillating back and forth rotational motion of the first bristle carrier 180. The second end 214 may also be formed arcuate or otherwise formed as shown. The second end 214 forms a joint joint with the distal end of the neck 106, or the second end 214 slightly to the distal end of the neck 106 if additional support of the second end 214 is needed. It may be extended. The elastomeric second bristle carrier 210 has a lower surface 215 extending across the inner partition 121 of the head 120. Since the lower surface 215 is connected to the upper edge of the side wall of the head base 160 in the region of the head 120, the shaft 200 is lowered into the slot of the first carrier 180 through the inner partition wall 121. Extends down the face 215.

The bristle holder 230 is firmly disposed in the recess 220 formed by the elastomeric second bristle carrier 210; It is designed to support a number of tooth protection elements 152, such as bristle tufts, elastomeric members, or a combination thereof. Thus, the shape of the bristle holder 230 and the recess 220 should be complementary to each other. In the illustrated embodiment, each bristle holder 230 and recess 220 take the form of an annulus, but each of them is of regular or irregular shape (eg, oval, diamond, square, etc.). You can also take The bristle holder 230 supports one or more, preferably multiple, dental protection elements 230 extending outward from a surface parallel to the surface thereof. The bristle holder 230 can support a plurality of different types of tooth protection elements; It should be appreciated that the elastomeric member is equally supported by or formed as part of the bristle holder 230, and is not limited to simply supporting the bristle tufts. The bristle holder 230 is formed of a suitable material, such as plastic, and is preferably a very rigid member that can provide the desired structural properties. However, according to another embodiment, the bristle holder 230 may be formed to have a hardness greater than, equal to or less than the hardness of the elastomeric material forming the elastomeric second bristle carrier 210.

The elastomeric second bristle carrier 210 including the bristle holder 230 may be formed using a conventional manufacturing method. In one embodiment, the elastomeric second bristle carrier 210 is formed around the bristle holder 230 in a conventional molding process; The bristle holder 230 is first properly disposed in the mold and then the elastomeric material is injected around the bristle holder 230 to form an elastomeric portion of the bristle carrier 210 around the bristle holder 230.

The elastomeric second bristle carrier 210 is preferably formed such that the bristle holder 230 lies on a plane above the head base 160, preferably above the top surface of the neck 106. Accordingly, the elastomeric second bristle carrier 210 forms an accumulation portion (rising portion) 225 leading to the upper surface 231 of the bristle holder 230 on the upper surface of the neck portion 106. In an exemplary embodiment, the accumulator includes a radial shoulder 237 extending around the bristle holder 230. Thus, the elastomeric second bristle carrier 210 runs downward toward the first bristle carrier 180. The recess 220 is formed by the riser 225.

The elastomeric second bristle carrier 210 also defines a cavity or hollow channel (eg, a through hole) extending from the first side 216 to the second side 218. As shown in detail in the side cross-sectional view of FIG. 4 and the cross-sectional view of FIG. 5, a cavity 240 is formed behind the bristle holder 230, the upper boundary of the cavity being adjacent to the bottom surface of the bristle holder 230. Formed by the disposed elastomeric material. The cavity 240 is preferably disposed over the sidewall of the head base 160 so that it can be free from all obstructions and the operator can clearly see through the cavity 240. In other embodiments, the cavity 240 does not have an open end, but its shaft may be formed with a pocket enclosed at the bottom of the bristle holder 230, or may be formed so that only one end is open. Optionally (as shown in FIGS. 2 and 3), the second hollow or hollow channel (eg, through hole) 240 is longitudinally extending from the first end 212 to the second end 214. Is extended. In this embodiment, the two channels intersect at the center of the second bristle carrier 210. It should be appreciated that the cavity 240 does not extend completely through the second bristle carrier 210. The cavity 240 acts as a shock absorbing pocket and allows the elastomeric second bristle carrier 210 to move vertically (up and down) when a force is applied to the elastomeric second bristle carrier 210. In particular, when a force is applied to the top surface (eg, top surface 231) of the carrier 210, the elastomeric second bristle carrier 210 is deformed or part of the carrier 210 around the cavity 240. Compresses downward due to the decay.

Due to its elastic properties, the second bristle carrier 210 returns to its relaxed state when the applied force moves. In other words, once the applied force is removed, the cavity 240 assumes its initial shape to impart shock absorbing properties to the second bristle carrier 210. It should be appreciated that by varying the dimensions of the cavity 240, the impact absorbing properties of the second bristle carrier 210 can be changed. For example, when the dimension of cavity 240 is increased, carrier 210 will be more easily deformed by the application of force. This is because when the user of the toothbrush 100 brushes his teeth and the tooth protector (brush head and / or elastomeric member) extending from the bristle holder 230 is in contact with the tooth and the surrounding area, the elastomeric second bristles In addition to the vertical movement of the carrier 210 is converted. Conventional brushing operations will impart numerous forces at different angles to the elastomeric second bristle carrier 210.

In addition, the elastomeric properties of the second bristle carrier 210 are further modified by the deformation of one or more openings 250 of the second bristle carrier 210 by the bristle holder 230. The opening acts to increase the elasticity of the second bristle carrier 210, since the confinement of the opening 250 results in removal of the elastomeric material.

In another embodiment, the top of the second bristle carrier 210 forms a hollow deformable domed structure. The bristle holder 230 forms the top surface of the domed structure, and forms at least one opening to allow air to enter and exit the cavity formed by the bristle holder 20. Thus, when a force is applied to the bristle holder 230 during brushing, the domed structure collapses at least partially when air in the cavity is discharged through at least one opening.

The elastic action of the elastomeric second bristle carrier 210 is enhanced cleaning, tooth polishing and / or because the second bristle carrier 210 has a plurality of tooth protection elements extending therefrom for contact with the gum face during brushing. It provides additional oral health benefits such as tooth cleaning. It should be appreciated that the tooth protection element may be disposed in an area other than the bristle holder 230. For example, some tooth protection elements may be attached to extend upward from the top surface of the carrier 210 surrounding the bristle holder 230.

6-12 show an elastomeric second bristle carrier 300 in accordance with another embodiment of the present invention. According to this embodiment, the elastomeric second bristle carrier 300 does not include a bristle holder (such as bristle holder 230, etc. of FIG. 5). Rather, the elastomeric second bristle carrier 300 is formed as a generally " floating " head portion having a range of motion in normal operation and / or when a force is applied thereto in normal use of the toothbrush 100. FIG. The elastomeric second bristle carrier 300 has a first end 302 disposed in close contact with the first bristle carrier 180, and an opposing second end disposed near or near the central end of the head 120. End 304. The elastomeric second bristle carrier 300 further includes a first side 306, an opposing second side 308, and an upper surface 310 and a lower surface 312 facing the inner partition 121. do. Top surface 310 is not a flat surface, but rather an arcuate surface (eg, a convex surface).

According to one embodiment, the elastomeric second bristle carrier 300 is supported only at the first side 306 and the second side 308 by the head base 160, so that the elastomeric second bristle carrier 300 is transverse. , Thereby forming an upper limit of the inner partition 121 of the head 120, thus forming as a "floating" elastomeric platform. Attaching the elastomeric second bristle carrier 300 to the head base 160 may be accomplished using conventional techniques, such as adhesives that integrally attach the two members or provide mechanical bonding during the molding operation. Since the first bristle carrier 180 is formed in the shape of a disc, the first end 302 is preferably arcuate to accommodate oscillating back and forth rotational motion of the first bristle carrier 180. The second end 304 may also be formed in an arc shape as shown, or may be formed in other forms. The second end 304 forms a joint with the distal end of the neck 306, or the second end 304 is the distal end of the neck 106 when additional support of the second end 304 is required. May extend slightly up. Accordingly, the bottom surface 312 is connected to the upper edge of the side wall of the head base 160 in this area of the head 100, so that the shaft 300 is in the inner partition 121 at the bottom of the bottom surface 312. It extends through the slot of the first bristle carrier 180 through.

The second bristle carrier 300 forms an enlarged cavity, hollow channel (eg, through hole) or pocket 320 extending only from the first side 306 to the second side 308, but the first It may be formed to extend from the end 302 to the second end 304. The cavity 320 is formed over the upper side edge of the head base 160 which serves as a point of attachment between the head 120 and the second bristle carrier 300. The second bristle carrier 300 is formed in a state in which the soft portion is joined to promote movement of the second bristle carrier 300 when a force is applied to the upper surface 310. For example, a longitudinal or transverse groove (ie, score) 330 is formed in the surface 317 and at least one top surface 310 that define the upper limit of the cavity 320. In the embodiment shown, a single groove 330 is formed across the surface 317. The groove 330 forms a soft portion in the longitudinal direction in the second bristle carrier 300 (so-called "living hinge"). It should be appreciated that the grooves 330 may be formed equally in the longitudinal direction from the first end 302 to the second end 304.

9 shows the second bristle carrier 300 in a relaxed state prior to applying a force to the upper surface 310. 10 to 12 illustrate the second bristle carrier 300 in a deformed state after a force is applied to the upper surface 310. When a force is applied to the upper surface 310, the upper surface 310 is deformed around a living hinge formed by one or more grooves 330. This results in the top surface 310 at least partially collapsed along the living hinge. The tooth protection elements 310 formed on the upper surface 310 are bent inward toward each other as shown in FIG. 10 by this deformation. Thus, the elastomeric second bristle carrier 300 may be considered a hinged block having shock absorbing properties. When the applied force is removed, the second bristle carrier 300 is returned to its relaxed state by the elastomeric properties.

The tooth protection element 340 extending upward from the upper surface 310 is a plurality of elastomeric members (shown in FIGS. 13-17) integrally formed with the elastomeric second bristle carrier 300. For example, the tooth protection element 340 may be formed by the same molding process of forming the elastomeric second bristle carrier 300. Thus, although the elastomeric second bristle carrier 300 is described as a bristle carrier, it should be appreciated that the carrier 300 does not necessarily include any bristle tufts.

In the above-described embodiment, it should be appreciated that the tooth head may comprise a plurality of stationary tooth protection elements disposed in different directions.

In another embodiment, FIGS. 21A-21C, the toothbrush 100 (and head 140) includes a head base 161 that partially forms the inner partition 125 of the head 140, and the head 140. FIG. A second movable bristle carrier 132 operatively mounted to the head). The second movable bristle carrier 132 includes a platform 134 having a first end 136 and a second end 138, a first end midpoint 141, and a second end midpoint 1412. And a midpoint 144 and a bottom 146. The protrusion 148 extends outward from the platform 134 at the first end 136 and is accommodated in the recess 130 of the first movable bristle carrier 181, so that the first carrier 181 and the second carrier are oriented. Provide a link between 132. In a preferred embodiment, features such as at least one leg 150 are integrally formed with the platform 134 and received by the head base 161 to support the platform 134. The at least one leg 150 may include a plurality of wide members of different shapes, and a member that can act as a support member is used to connect the platform 134 to the head base 161.

In various parts of the present invention, when changed in accordance with various embodiments of the present invention, the range of motion and shape of the first movable bristle carrier 181 and the second movable bristle carrier 132 will vary. The motion of the first movable bristle carrier 181 is as described above, and can be changed by changing transmission or driving of the driving unit to the first movable bristle carrier. Such modifications are well known in the art.

Since the movement of the first movable bristle carrier 181 imparts movement directly to the platform 134, a change to the movement of the first movable bristle carrier 181 changes the movement of the second movable bristle carrier 132. I will. In addition, fixation and structural changes of the second movable bristle carrier will change the movement well. Various embodiments have been designed such that the protrusion 148 of the platform 134 is tightly received in the recess 130 or the protrusion 148 frictionally accommodates the recess 130.

Other changes to the second movable bristle carrier include the legs 150 and the platform 134 being formed of a rigid or elastomeric material. Different combinations of rigid legs or elastomeric legs 150 and platform 134 will provide for a variety of forms and ranges of motion of platform 134. Another factor influencing the shape and extent of motion of the platform 134 is the placement and number of legs 150. The preferred embodiment of the present invention shown in FIGS. 21A-21C includes one leg 150 formed integrally with the platform 134 around the second end midpoint 142. The movement of the first movable bristle carrier 181 imparts a torsional movement on the leg 150 as shown by arrow B, and the first movement of the second movable bristle carrier 132 parallel to the first end 136. Not only does it impart lateral movement of the first end 136, but also rotates the platform 134.

In another embodiment of the present invention, as shown in Figures 18 to 20, the first leg 150 is formed integrally with the platform 134 at the first end intermediate point 141, the second leg 150 ) Is integrally formed with the platform 134 at the second end intermediate point 142. The legs 150 may be combined with other legs 150 as shown in FIGS. 22-25, or may be formed integrally with the platform 134 at the midpoint 144 alone.

18-25 illustrate different variations and combinations of tooth protector 152 including bristles and elastomeric tooth protectors. 18-20 illustrate a second movable bristle carrier with a short elastomeric wall of varying size and placement. Figure 22 shows a second movable bristle carrier 132 formed with a short elastomeric wall with a cuffed top surface. Figure 23 shows a second movable bristle carrier 132 formed with a short elastomeric wall with protrusions. Figure 24 shows a second movable bristle carrier 132 with short elastomeric walls that are tilted or bent to one side without being all parallel to each other. Figure 25 shows a second movable bristle carrier 132 in which a short elastomeric wall and a hump and lower bristle portion are combined. This variant is for illustration only and can be realized by a combination of tooth protection elements.

26 to 28 show yet another embodiment of the present invention using a head structure. The handle 102, the neck 106, the drive, and the head base 161 are formed similarly to those described above. However, according to this embodiment of the present invention, the first movable bristle carrier 181 is formed with one or more protrusions 202 directed towards the platform 134 of the second movable bristle carrier 132. The platform 134 is formed as described above and further includes one or more protrusion contact points 204. Movement of the first movable bristle carrier 181 imparts movement of the platform through contact of the protrusion contact point 204 and the protrusion 202. In addition, the materials of legs 150 and platform 134 will change the range and shape of motion of the second movable bristle carrier 132 as well as the placement of legs 150. 28A-28C illustrate embodiments in which movement of the first movable bristle carrier 181 is imparted on the platform 134. As the first movable bristle carrier 181 rotates along the arrow C, the platform 134 is moved to the first end 136 parallel to the first end 136, as in the direction of rotational movement of the arrow C. FIG. Give lateral movement. 26-28 show protrusions 202 not connected to platform 134, it should be considered that the protrusions 202 may be connected to platform 134 at protruding contact points 204.

29 to 31 show yet another embodiment for generating various movements. FIG. 29 illustrates the motion of the platform 134 when the leg 150 is placed alone at the midpoint 144 of the platform 134. Thus, the platform 134 will rotate along the arrow D, giving greater motion to the second end 138 of the platform. 30 illustrates an embodiment in which legs 150 are pivotally connected to base 161. This embodiment also allows for greater movement of the second end 138. The above-described movement will occur regardless of how movement from the first movable bristle carrier 181 is imparted to the platform 134. 31A to 31C show various positions generated during the movement of the structure shown in Figs. 29 and 30. Figs. These structures allow the second end of the platform 134 to rotate about an intermediate point 144, as shown by arrow E, when the first movable bristle carrier 181 oscillates across arrow F. As shown in FIG. And a second movable bristle carrier to increase the lateral movement of 138. 32 illustrates another exemplary head embodiment. The handle 102, the neck 106, the drive unit, and the head base 161 are the same as described above. The second movable bristle carrier 232 is operably connected to a second drive mechanism for moving the second movable bristle carrier 232 in a third direction. The second drive feature is in selective contact with the second movable bristle carrier 232 of the platform 234, perpendicular to the first movable bristle carrier 180 in the preferred embodiment (the direction shown by arrow G). At least one cam surface 400 for causing the movement.

FIG. 33 illustrates another embodiment spanning from the second end 138 to the first end 136 of the platform 134. Due to this positioning of the leg 150, the platform 134 can be "locked" back and forth across the longitudinal axis of the tooth 100 in the direction of the arrow H. The leg 150 is attached to the second movable bristle carrier 132 through the receiving groove 410.

36 and 37 show another embodiment in which the first bristle carrier 183 performs a rotational or circular motion of the bristles 185 by pivotally rotating around an axis. In various embodiments, the first bristle carrier 183 can rotate around the post 190, and any suitable form that allows this movement can be used. Since the movement of the first bristle carrier 183 is a rocking motion or a vibration motion, the first bristle carrier 183 is first pivoted around the post 190 in one direction through the movement range, and then in the opposite direction through the movement range. It is pivoted around the post 190.

In one embodiment, the toothbrush 100 further comprises a second movable bristle carrier 133 formed of suitable material (s), such as, for example, elastomer and / or non-elastomeric as described above. The second bristle carrier 133 may include a first pivot part 205 pivotally connected to the first bristle carrier 183 at the first pivot mounting part 207, and a brush part at the second pivot mounting part 211. And a second pivot portion 209 pivotally connected to 104. The second bristle carrier 133 may be freely moved from the brush 104, rather than the first pivot portion 205 and the second pivot portion 209. By oscillation of the first bristle carrier 183, the second bristle carrier 133 also swings, and the second bristle carrier 133 pivots about the first pivot portion 205 relative to the first bristle carrier 183. And pivots about the second pivot portion 209 relative to the brush portion 104. In this way, the second bristle carrier 133 is moved in a range of motion similar to the range of motion of the first bristle carrier 183. The center of rotation of the second bristle carrier is the second pivot portion 209, and the second bristle carrier 133 is moved in a fan shape.

Since the second bristle carrier 133 is seated on the curved portion 217 formed in the brush part 104, the second bristle carrier 133 is generally formed of the brush part 104 and / or the first bristle carrier 183. Equal to or extend outward from the surface. In this embodiment, the second bristle carrier 133 and the brush part 104 take the form that the second bristle carrier 133 does not impact the brush part 104 during swinging.

In the embodiment shown in Figure 34, the first and second pivot mounts 207, 211 include notches in the first bristle carrier 183 and brush holder 104, respectively. The first and second pivot parts 205 and 209 are provided with a first and second pivot mounting part 207 and 211 in a sufficiently rigid manner so that the second bristle carrier 133 is not easily separated from the toothbrush 100 during brushing. Combined in. This can be done in a variety of ways, for example, by pressing, rubbing, snapping and the like. In the illustrated embodiment, although pivots 205 and 209 are inserted into notches 207 and 211, it should be appreciated that the pivot and pivot mounts may take other engagement forms. For example, the pivot portion may be connected to the pivot mount by means such as a pin (not shown).

The pivots 205 and 209 are formed such that the second bristle carrier 133 pivots with respect to the first bristle carrier 183 and the brush part 104. This can be accomplished by various configurations. For example, the pivot portions 205, 209 have sufficient flexibility, such as, for example, elastomeric materials or flexible non-elastomeric materials, so that they can be bent or flexed relative to the first bristle carrier 180 and the brush portion 104. have. In this embodiment, each pivot portion acts as a "living hinge".

In another embodiment, the pivot portion itself does not need to be bent when the pivot portion rotates with respect to each pivot mount in the form of "ball and socket". In another embodiment, the pivot portion may be mounted to the pivot mount via a pin as described above. Those skilled in the art will appreciate that other forms may be used to achieve the intended function.

The second bristle carrier 133 includes a plurality of second bristle 186. The bristles 186 can have various sizes, shapes, amounts, lengths, shapes, materials, and combinations thereof, as described for the plurality of first bristles 185. Therefore, what is described with respect to the plurality of first bristles 185 may also be applied to the plurality of second bristles 186.

The fan swing of the second bristle carrier 133 moves the plurality of second bristles 186 into corresponding fan swings. This rocking, in conjunction with the rocking of the plurality of first bristles 185, provides additional powered bristle area and movement to provide cleaning, whitening and / or massage. In addition, as will be appreciated by those skilled in the art, in various embodiments, the movement of the plurality of second bristles 186 is different from the movement of the plurality of first bristles 185, and thus, through a combination of exercises. The efficiency of the toothbrush 100 can be enhanced.

It should be appreciated that the bristles may be associated with the second bristle carrier 133 in a variety of ways, regardless of the material forming the second bristle carrier 133. For example, if the second bristle carrier 133 is formed of an elastomeric material, the elastomeric bristles may be associated during molding. However, by including one or more inserts (not shown) having the same bristles as described above, the non-elastomeric bristles can be inserted. The insert includes, for example, a plastic insert with a tuft to which non-elastomeric bristles are attached.

Alternatively, if the second bristle carrier 133 is formed of a non-elastomeric material such as plastic, the non-elastomeric bristles may be attached as described above. However, by including one or more inserts with elastomeric bristles in the second bristle carrier 133, the elastomeric bristles can be associated. Thus, the second bristle carrier 133 can include elastomeric bristles, non-elastomeric bristles, or a combination thereof. Those skilled in the art will appreciate that many bristle combinations and forms may be possible.

In other embodiments shown in FIGS. 37-39, the second bristle carrier 133 may generally move in the vertical direction, ie radially inwards and outwards relative to the longitudinal axis of the toothbrush. A drive shaft 330 similar to that shown in FIGS. 1A-1C includes at least one cam, curved portion, generally journal or offset portion 340, which is longitudinally aligned with and integrally formed with the second bristle carrier. . Since the offset part 340 extends in the radial direction from the longitudinal axis of the drive shaft 330, the offset part 340 may contact the second bristle carrier 133 during the rotation of the drive shaft 330. The contact between the offset portion 340 and the second bristle carrier 133 exerts a radial force on it, thereby moving the second bristle carrier 133 vertically or radially.

As the drive shaft 330 continues to rotate, the offset portion 340 stops contact with the second bristle carrier 133 and returns the second bristle carrier 133 to its original position. In this way, the second bristle carrier 133 swings vertically during the rolling operation of the toothbrush.

The vertical swing size of the second bristle carrier depends on the radial distance from which the offset portion 340 extends from the longitudinal axis of the drive shaft 330. In another embodiment, the second bristle carrier 133 includes a lobe or tab 350 extending radially inward from the second bristle carrier 133. In this embodiment, the vertical size of the second bristle carrier 133 is incidentally dependent on the distance that the tab 350 extends inwardly from the second bristle carrier 133.

Since the second bristle carrier 133 includes sufficient flexibility, it will move vertically when actuated by the offset portion 340 and will return to its original position when the vertical force is removed. This can be accomplished by using generally an elastomeric second bristle carrier 133 or a non-elastomeric (plastic) second bristle carrier having sufficient flexibility as described above. This may also be achieved if the pivot portions 207, 211 of the second bristle carrier 133 are of sufficient flexibility, for example elastomeric. Since the pivots 207 and 211 have sufficient flexibility, the vertical movement of the second bristle carrier does not impose unnecessary vertical force or shear force on the first bristle carrier 183 and the It does not interfere with the fan movement and does not interfere with other parts of the toothbrush 100. In addition, since the driving shaft 330 and the offset portion 340 have sufficient hardness with respect to the second bristle carrier 133, when the driving shaft 330 and the offset portion 340 are in contact with the second bristle carrier 133. Do not deflect unnecessarily.

Vertical rocking of the second bristle carrier 133 imparts additional bristle movement to the teeth and / or gums. This further enhances the brushing and massage effect of the bristles.

37 to 39 show one cam or offset portion. Therefore, the second bristle carrier 133 receives one vertical swing every one rotation of the drive shaft 330. Optionally, the second bristle carrier 133 may receive additional swings per revolution of the drive shaft 330 by providing additional cams (not shown) to the drive shaft 330. Those skilled in the art may recognize that multiple cams may be arranged on the drive shaft 330 to obtain the required number of swings per revolution of the drive shaft and how the teeth are formed to achieve this function. .

The vertical movement of the second bristle carrier 133 can be varied by providing a non-uniform pitch around the outer periphery of the drive shaft 330 and / or by modifying the radial offset of the cam from the longitudinal axis of the drive shaft 330. . For example, if the cams were equally spaced apart, the second bristle carrier 133 would swing at a constant frequency. However, if the cams were not equally spaced apart, the second bristle carrier 133 would not rock at a constant frequency but would rather rock in a complex manner. Likewise, if the radial offsets of the cams were changed from one another, the magnitude of the vertical motion of the second bristle carrier 133 would change from one swing to another. Changing the vertical movement of the second bristle carrier 133 will continue to change the movement of the bristles relative to the teeth and gums.

40 and 42 illustrate a second bristle carrier suspended from the brush part 104 to form a gap 360 between the second bristle carrier 133 and the brush part 104. 133). This may be accomplished by including a curved portion 217 that is deeper than the thickness of the second bristle carrier 133. Those skilled in the art will also recognize other ways in which toothbrush components are applied to achieve this function. Suspension of the second bristle carrier 133 from the brush portion 104 reduces friction between these two members, thereby increasing the softness of the toothbrush operation, reducing the wear of the parts, and reducing the power consumption, thereby reducing battery life. And / or make it possible to use small and inexpensive driving components.

To prevent debris, food, toothpaste, saliva, and other substances from entering the gap 360, the toothbrush 100 extends from the brush portion 104 to the second bristle carrier 133 a curtain or wall 370. By further including, a seal is formed on the gap 360. The curtain 370 may optionally be attached to the second bristle carrier 133. The curtain 370 is sufficiently flexible to bend in a sectoral motion of the second bristle carrier 133 and does not excessively interfere with the motion. The curtain 370 is made of an elastomeric material or a non-elastomeric material.
