JPH08103332A - Motor toothbrush with vertical motion bristle - Google Patents

Abstract

PURPOSE: To provide a motor toothbrush with vertical motion bristle easy to remove dental plaque without hurting a tooth and gingiva and with widely improved tooth-brushing efficiency, by directly or indirectly mounting bristle bundles on a wire- or band-shaped vibration transmission and amplification body, and transmitting vibration and giving vibration to an end of the amplification body by attaching them on the head part of a toothbrush handle. CONSTITUTION: A bristle bundle 3 is indirectly mounted on a wire- or band- shaped vibration transmission and amplification body 6 putting a stem 4 out. Or, direct mounting on the vibration transmission and amplification body is also preferable. The vibration transmission and amplification body 6 is mounted on the head 2 of a tooth brush to give vibration to an end 6' of the wire- or band-shaped vibration transmission and amplification body 6. As a result, the wire- or band-shaped vibration transmission and amplification body vibrates and resonates and tips of individual bundles connecting thereof are respectively moved vertically by the vibration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush that causes the tips of individual bristles of an electric toothbrush to move up and down.

[0002]

2. Description of the Related Art In conventional electric toothbrushes, the tips of individual bristle bundles do not move up and down, so that they cannot cope with unevenness on the tooth engagement surface or the tooth side surface. . (B) In order to reach the tip of the hair on the concave surface, excessive force was applied to the tip of the hair and excessive vibration was applied. For this reason, the teeth and gums were damaged, the vibration of the handle echoed on the teeth, and the discomfort was strong. (C) In order to reach the tip of the bristles on the concave surface, the conventional electric toothbrush is often inclined by 45 degrees with respect to the side surface of the tooth, and the bristles bend and wear the gingiva, so that the bristles only partially touch the teeth. Since it was not present, the polishing efficiency was significantly reduced. (D) In order to deal with the unevenness of the polished surface, the length of the bristles became longer than necessary, the tips of the bristles were bent, and the period of use of the toothbrush was short, and it was difficult to dry and was unsanitary. .

[0003]

Although many electric toothbrushes have been developed in order to improve the polishing efficiency, they have not been able to sufficiently cope with these problems. The present invention solves these problems by moving the tips of the individual hair bundles up and down, and can meet the strong demands of users.

[0004]

[Means for Solving the Problems]

(A) The bristles of the toothbrush are directly or indirectly attached to the wire-shaped or band-shaped vibration transmitting and amplifying body. (B) The head of the toothbrush handle is provided with the device configured in (a), and vibration is applied to one end of the wire-shaped or band-shaped vibration transmitting and amplifying body. The configuration is as described above.

[0005]

By applying vibration to one end of the wire-shaped or band-shaped vibration transmitting and amplifying body, the wire-shaped or band-shaped vibration transmitting and amplifying body vibrates and resonates, and the individual hair bundles connected to this vibrates and resonates. The tips of the hairs also individually move up and down due to the vibration.

[0006]

【Example】

(A) The hair bundle 3 has a wire-shaped or band-shaped vibration transmission and amplification body 6,

As shown in FIG. 1, the core rod 4 may be taken out and attached indirectly, or may be directly attached to the vibration transmitting and amplifying body. (B) As a material for the wire-shaped or strip-shaped vibration transmitting and amplifying body, metal, plastic, or rubber elastic material can be considered. (C) The vibration transmitting and amplifying body may have a linear shape,

FIG. 3

As shown in FIG. 4, it is preferable that the shape easily vibrates and that a peak of vibration is present at a specific place. (D) In addition,

As shown in FIG. 5, the root portion of the hair bundle 3 may be planted in the elastic film-like material 7 and used in place of the head cover 2'of the handle of the toothbrush, or as the head cover 2 '. The elastic film material 7 may be used together.

[0007]

【The invention's effect】

(A) The tips of the individual hair bundles conform to the irregularities of the tooth surface and are well-adapted, so that the brushing efficiency is greatly improved and plaque is easily removed. (B) Since the force applied to the tip of the hair and the strength of vibration can be greatly reduced, the handle does not cause discomfort even if it touches the teeth, and the teeth and gums are not damaged. (C) Since the toothbrush bristle length can be considerably shortened because it can deal with the unevenness of the tooth surface, the bristle tips are less likely to bend, the service life can be greatly extended, and the hair can easily dry. Hygienically improved. (D) By placing the root part of the bunch of hair on a flexible film-like material and installing it on the head of the handle of the toothbrush, the water, polishing residue, and polishing powder at the time of α toothbrushing will be elastic film-like. Since it is covered by an object and does not penetrate into the head of the handle, vibration is not disturbed and it can be kept clean forever. b Vibration is not directly transmitted to the head of the handle of the toothbrush, and there is little discomfort when the teeth hit the head of the handle. c There is no direct contact between the vibration transmitting and amplifying body with the hair bundle attached or the core rod and the head of the handle, and wear of this portion can be prevented. d In manufacturing, it is advantageous because the process can be omitted.
