Description

  The present invention relates to a toothbrush, and more specifically, the contact area and frictional force between the tooth and the brush while the flocked body in which the brush is implanted elastically moves up and down or left and right in the head of the toothbrush according to the shape of the tooth. The present invention relates to a toothbrush that is further increased to maximize the effect of removing plaque and food residues by brushing and to be useful for oral hygiene.

  Usually, the used toothbrushes have a brush head brushed at a fixed interval on a flat head, which increases the adhesion according to the curved surface of the teeth and maximizes the effect of the brushing. In practice, various measures are taken such as adjusting the height so that the lengths of the brushes are different from each other, increasing or decreasing the diameter, or arranging the brushes in various shapes.

  However, in the conventional toothbrush, the brush is planted on the flat head, so the brush does not adhere to the shape of the tooth when brushing, and the contact area is small, so the frictional force is also reduced, and thus when brushing. Further, since the frictional force of the brush does not act uniformly on the tooth surface, the brushing effect has only been halved. Therefore, the present invention seeks to provide a toothbrush that can eliminate the problems of such conventional toothbrushes.

  In particular, in the invention already filed by the present inventor (Korean Patent Application No. 10-2010-0025447), the independently implanted flocked body is bonded to the lower elastic member by various methods in the head of the toothbrush. The brush is increased in frictional force by a method in which the flocked body is elastically actuated up and down, left and right, front and rear by an elastic member in the head at the time of brushing. However, in the present invention, basically, it is possible to reduce the manufacturing cost by enabling the injection of the toothbrush by integrating the flocked body and the head of the toothbrush with one single material without separating them. By making it possible to manufacture a toothbrush that can be elastically operated more easily than existing methods, the contact area of the brush of the toothbrush can be made uniform regardless of the shape of the tooth during brushing. , Increase the frictional force between the brush and the tooth can maximize the plaque removal effect, simplify the manufacturing process and reduce the price of the toothbrush, It is intended to provide a toothbrush that can be used for the health of the oral cavity of mankind by purchasing a sex toothbrush so that it can be used effectively to improve the health of teeth and gums.

  The toothbrush of the present invention is provided with a through-hole penetrating in the vertical direction in the head of the toothbrush, and at least one portion of the flocked body in which the brush is planted inside the through-hole is connected to the head and the front and rear in the head of the toothbrush. Or at least two portions of the flocked body are partially connected to the head at the upper or lower side of the left and right sides, or at least two portions of the flocked body are connected to the front, rear, left and right sides. By connecting at the top or bottom, the brushed body can move elastically up and down or left and right within the head of the toothbrush during brushing, maximizing the contact area while the brush moves elastically according to the tooth shape Thus, it is possible to maximize the effect of the brushing by increasing the frictional force.

  In the toothbrush of the present invention, a flocked body in which a brush is planted is installed in a through-hole penetrating the head of the toothbrush in the vertical direction. A toothbrush having a flocking body and a handle portion that are partially connected at each other, partially connected at the upper and lower sides of the left or right, or partially connected at the front, rear, left, and right and capable of functionally elastic operation. Can also be injected at a time, so that the manufacturing cost can be reduced. In addition, this toothbrush can maximize the contact effect between the teeth and the brush when removing plaque by maximizing the contact area between the tooth and the brush when removing the plaque by allowing the flock to move up and down or left and right at the time of brushing. It is an invention that has great expected effects, such as being useful for oral hygiene.

It is a left sectional view showing the operation state for explaining the elastic movement of the toothbrush according to the present invention in the vertical and horizontal directions.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  That is, as shown in FIG. 1, the toothbrush 1 of the present invention penetrates the through hole 3 in the vertical direction of the head 2 of the toothbrush, and the through hole 3 is at least one between the flocked body 5 and the head 2. The flocked body 5 is inserted in the through hole 3 so that the flocked body 5 in which the brush 4 is planted and the head 2 of the toothbrush are integrally connected to each other. The upper part or the lower part of the side can be partly connected by at least one connecting part 6 having various forms of line, face or bar shape. Explaining this in detail, the through-hole 3 of the head 2 is penetrated into at least one portion as much as necessary or length around the front, back, left and right of the hair transplant body 5 inside the head 2. At this time, the through hole 3 is penetrated by leaving at least one part of the connecting part 6 having a line, surface or bar shape so that the flocked body 5 and the head 2 are integrated without being separated from each other. Depending on the position, shape or number of the connecting portions 6, the brushed body 5 is elastically operated in various directions inside the head 2 during the brushing operation, and the contact area between the teeth and the brush 4 and the frictional force are further increased. It is characterized in that it can enhance the plaque removal effect and can be further used for oral hygiene. By configuring the toothbrush in this way, the brush 4 is moved first according to the form of the tooth by the forces in various directions received on the wrist at the time of brushing. Therefore, the brush 4 is secondarily planted. The flocked body 5 is subjected to force. As a result, the connecting portion 6 is primarily distorted by the force, and at the same time, the force condenses on the connecting portion 6 and acts as an elastic restoring force to instantaneously restore the original shape, thereby flocking the hair. While the body 5 is elastically operated vertically and horizontally, the contact area between the teeth and the brush 4 and the frictional force can be further increased to increase the effect of removing plaque and food residues, which can be further used for oral hygiene. It is characterized by doing so.

  For this reason, in this invention, the through-hole 3 provided in the head 2 is wider than the circumference | surroundings of the flocked body 5 in which the brush 4 is planted, and the said flocked body 5 isolate | separates from the head 2 in the through-hole of the head 2 of a toothbrush. Connection parts with various shapes such as various thicknesses, lines, surfaces, bars, etc. in the upper or lower part of the front / rear side, the upper part or lower part of the left / right side, or the upper part or lower part of the front / rear left / right side. The hair transplant body 5 and the head 2 are connected by at least one part by 6 and various methods such as a double injection method or high frequency bonding are used for elastic operation of the hair transplant body 5 in the same manner as the existing method. In addition, there are many advantages of using a single injection method when manufacturing the toothbrush, which can save working time and reduce mold and material costs. Moreover, when injecting a toothbrush, the head 2 and the flocked body 5 provided in the through-hole 3 of the head 2 can be made simultaneously.

  As one embodiment, in the embodiment of FIG. 2, the connecting portion 6 is positioned in the front-rear direction between the head 2 and the flocked body 5, and in the embodiment of FIG. 3, the connecting portion 6 is the head 2 and the flocked body 5. 4, the flocked body 5 is divided into two parts in the embodiment of FIG. 4, and in the embodiment of FIG. 5, only a necessary part in the flocked body 5 is cut and partial flocking is performed. Although the body 9 is made, the partial flocking body 9 can be made in a rectangular shape, a square shape, or various shapes. In the embodiment of FIG. 6, the connecting portion 6 is positioned at a front portion between the head 2 and the flocking body 5. In order to limit the width of movement of the flocked body 5 when necessary, the head 2 is provided with a convex protrusion 10 and the flocked body 5 is provided with a concave groove 11 corresponding to the convex protrusion. Many methods can be applied as necessary as described above.

  As shown in the sectional views of the embodiment of FIGS. 7 and 8, the connecting portion 6 is partially connected to the head 2 at the upper or lower part of the front and rear of the flocking body. In the illustration of FIG. In the toothbrush head 2, any one of various methods such as double injection and high-frequency bonding through an elastic connecting member 8 made of one material selected from soft synthetic resin, silicone and synthetic rubber. This indicates that the elastic force of the flocked body 5 that moves in the head 2 at the time of brushing is further strengthened. FIG. 10 shows a perspective view of the lower part of the toothbrush 1 when the elastic connecting member 8 is applied. Such an elastic connecting member 8 is similar to that shown in FIG. 2, 3, 4, 5, 11, 12, and 13 can be applied, and various applications of the elastic connecting member 8 to the portion of the flock 5 that needs elasticity. Is possible.

  In the example of FIG. 11, when the case of the four rows is taken as a reference, the flocked body 5 is divided into four individual flocked bodies 13 a to 13 d and separated laterally for elastic operation. If necessary, they can be separated separately in the vertical direction. Therefore, as can be seen from the above example, if necessary, whether the elastic operation is performed only on both side parts by dividing into three parts by dividing into two rows in one side and two rows in the center. It is possible to separate only the central two rows and perform elastic operation only on the central row portion while leaving both side portions as they are, and perform elastic operation on two rows by dividing the two rows on both sides into two parts. It can also be done. In addition, when a vertical segment is required, it can be elastically operated by performing various vertical segments as required, as used in the horizontal segment. It is also possible to segment only the central part into a quadrangular shape and move only that part. As described above, as illustrated in FIG. 11 of the present invention, the case where the brushes are implanted in four horizontal rows is described as an example, and each individual flocked body 13 segmented into four parts is a toothbrush. The individual flocked body 13 is thinly partially connected to the head 2 at the top, bottom, top, or bottom in the through-hole of the head 2 in the form of lines or surfaces of various forms at the front and rear. The toothbrush head 2 is elastically operated left and right. Further, here, segmenting or separating the flocked body 5 does not mean complete cutting without connection between the flocked body 5 and the head 2 in view of the flow of this specification. It is clearly intended to mean that it is connected to the head 2 by one or more connecting parts 6.

  If necessary, several elastic connecting members 8 having a pin shape may be partially fixed between the individual flocked bodies 13a to 13d by a method such as rubber injection or high-frequency bonding. You can also.

  Of course, as shown in the drawing, the head 2 can be implemented in various shapes such as a rectangle or an ellipse in plan view. When the head 2 is an ellipse, the through hole 3 and the flocked body 5 are also oblong. Can be made to form.

  In FIG. 12, the individual flocked body 13 is further cut into individual partial flocked bodies 12 having one or more necessary flocks, and the individual partial flocked bodies are separated from each other on the front, rear, left, and right sides of the individual partial flocked body 12. By connecting with two or more connecting portions 6, many individual partial hair transplant bodies 12 can be formed in a lattice shape within the head 2 and can be elastically operated within the head 2. More specifically, the individual flocked body 13 is cut into a plurality of individual partial flocked bodies 12 having one or more flocked holes, and one or more planted objects are formed in the through holes 3 provided in the head 2. The individual partial flocked bodies 12 having pores are connected to each other by one or more connecting parts 6 on the front, rear, left and right sides of each individual partial flocked body 12, and in particular, the individual flocked body 13a and the individual flocked body 13d are individually separated. The partial flocked body 12 can be connected to the head 2 by a connecting portion 6 at the side as shown in the figure. Therefore, the individual partial flocks 12 divided into a large number are connected to each other like a net in the head 2 of the toothbrush so that they can be elastically operated.

  13 illustrates that the reinforcing member 7 is used to further strengthen the elastic force of the head 2 and the flocked body 5, and various reinforcing members 7 are illustrated in the example of FIG. In order to further strengthen the elastic force of the flocked body 5 that moves in the head 2 at the time of wiping, various materials and kinds of reinforcing members 7 that are harmless to the human body can be used before the injection. For example, a rectangular or flat plate spring, a hairpin type double wire, a twisted wire, a coil spring or the like is used to horizontally or vertically mold the top or bottom where the head 2 and the flocked body 5 are connected. The toothbrush is ejected while being fixed inside, or one of the reinforcing members 7 is selected after the toothbrush is ejected and fitted into the head 2 and the flocked body 5, so that the elasticity of the flocked body 5 is further increased during the cleaning. It can also be configured to ensure the operation. In the illustration of FIG. 6, the flocked body 5 connected to the head 2 by one connecting portion 6 in front or rear in the head 2 is shown in a cross-sectional view in a left-right direction.

  When brushing is performed using the toothbrush 1 of the present invention that can be configured as described above, the brush 4 and the tooth 4 are moved while the flocked body 5 on which the brush 4 is planted elastically moves up and down or left and right according to the form of the tooth. As a result, the more effective brushing can be performed. This is because the flocked body 5 in which the brush 4 is planted is fixed to the head 2, and the flocked body 5 has a shorter horizontal and vertical width than the through-hole 3 of the head 2. In addition, it is possible to secure a clearance of the flocked body 5 that is elastically actuated up and down or left and right within the head 2, and the flocked body 5 moves elastically during brushing, and the brush 4 moves according to the form of the teeth. However, the contact area and the frictional force can be increased to double the effect of the brushing.

  The present invention is based on a bath method useful for patients with periodontal disease by adjusting the pressure applied to the teeth by the user of the toothbrush to minimize tooth wear and periodontal tissue damage due to brushing. The cleaning can be made easier to use to help with gingival cleanliness and periodontal tissue health.
