Abstract

[Challenge] Teeth brushing has a long handle, and children have become accustomed to exercise. Even if the toothbrush is short, if the handle is improved so that it can be operated with your fingertips, the range of motion of the toothbrush head will be expanded, allowing you to brush every nook and cranny. To provide a reasonable handle part for a toothbrush. [Solution] A handle part that can be handled with your fingertips enables highly accurate brushing. It is sized to fit in the palm of your hand and can be handled with three fingers (thumb, index finger, middle finger), and has a hemispherical protrusion at the back of the head, with a tube inserted from the back to form the handle. To brush the curved surfaces of teeth with different angles, use the tips of the bristles to catch the contact surface you want to brush, hold three fingers in place, and brush forward, backward, left, right, up and down. Even if you change the way you hold it with your fingertips, the elasticity of the protrusion and handle grip your fingers, making it possible for the cylindrical tube to send equal pressure to the contact surface of the bending teeth.

Description

field of technology

Since 1907, plastic has been created and has a history of scraping off excess material. Plastic waste has reached its peak, and there is debate about what to do about marine environmental pollution. Recognizing that plastic is a limited resource, a short but functional toothbrush is desirable.

Motor habits such as gripping the long handle of a toothbrush and switching hands are widely practiced. Each time the tooth moves around a 360-degree curved surface and you re-grip it and change the position of the handle, the strength of the contact surface of the teeth changes, resulting in a rough polishing method. There is a sloppyness to the action of grasping, not paying attention to the details. The long handle gets in the way of areas that are difficult to polish, resulting in areas that are not polished enough on a daily basis, making it impossible to eliminate the cause of tooth decay. In other words, it can be said that the long handle hinders smooth physical technique.

Tools are things that can be learned from the ``craftsmanship'' and are created through the functions of the fingertips (physical techniques) and training. The essence of physical techniques evolves the tools at the fingertips and evokes movement habits. The nerves to the fingertips and the tools work together to maintain (beauty), which means selecting the tools. A long handle can be said to be a useless item.

Accurate and gentle tooth brushing is essential to prevent tooth decay and periodontal disease.
To achieve this, it is necessary to operate the short handle near the mouth in order to bring the toothbrush brush into contact with all the teeth or gums in the oral cavity through 360 degrees and to move and turn the toothbrush.

An oral care toothbrush comprising a brush part (1) made of a bundle of hairs, a head part (2) having the hair bundles implanted on the tip side , and a handle part (4), the head part One or two hemispherical pieces provided on the rear end side, for holding the oral care toothbrush in a pinching manner with the thumb, index finger, and middle finger, and twisting the handle part (4) with the thumb, index finger, and middle finger as a point of emphasis. The cylindrical and elastic handle portion (4) has a protrusion (3) consisting of a protrusion , and is placed over the head portion (2) with the protrusion (3) inscribed, A toothbrush for oral care that is long enough to fit in the palm of your hand.

The handle portion is a tube made of a soft material.
The length of the handle is palm-sized.
That is, a soft material tube with a length of 3.5 to 7.5 cm is used, but a length of 5 to 6 cm is effective and preferred.
A tube is inserted and used as a handle so as to encompass the hemispherical protrusion. Steering of the handle begins with the thumb and turns using the roundness of the tube. The two fingers (index finger, middle finger) follow the thumb and assist in twisting as a handle while changing the placement of the fingers. Since the width of an adult male's two thick fingers exceeds 4 cm, the length of the handle should preferably be 5 cm or more and 6 cm.

By holding the handle with three fingers (thumb, index finger, and middle finger) and manipulating it with your fingertips, you can care for each tooth individually, and the shape has been designed to facilitate a wider range of motion. That is, there is an effect of widening the range of motion of the brush portion. Since the insertion depth of the handle can be changed, it can be used regardless of age or gender. You can apply the bristles on the brush part to the area of your teeth you want to brush, feel the contact surface with your fingertips, and brush vertically and horizontally.

The closer the distance between your fingertips and the toothbrush head, the better in order to capture all the contact surfaces of your teeth, and the brushing action is all about how you can reach the area you want the brush to reach, how much force you apply to uneven teeth, and how well it feels to be brushing cleanly. encourage. In order to widen the range of motion of the brush part within the oral cavity, it is even more effective to apply flexibility in changing the grip of the fingers and rotation of the wrist. Even if you pinch the handle with three fingers, you need to push, pull, and steer up, down, left, and right, which is equivalent to the gripping force, and a moderate amount of force is required to make contact with the irregularities or gaps of the teeth. For this reason, the round protrusion and twisting of the tube, which serve as the focal point, enable three-finger steering.

Toothbrushing involves continuous movement of the toothbrush head, which involves a wide variety of movements, front, back, left, right, up and down. The roundness and elasticity of the tube makes it possible to guide the head instantly to any angle on the tooth surface by rotating the handle with three fingers. The cylindrical elastic tube can create a flexible and delicate force on the handle that is operated with three fingers, and it has a synergistic effect with the round protrusion that is the focus point, and the soft material fits well with the two fingers other than the thumb. It has a structure that is easy to handle for the following range of motion.

The moderate bending motion of the fingers applies gentle and even force to the surfaces of the teeth and gums, allowing you to be aware of the tips of the bristles in all parts of the oral cavity, and accurately brushing each strand one by one while feeling the unevenness of the teeth with your fingertips. It can be polished to Since the short handle is operated with your fingertips near your mouth, you can attack between your teeth with pinpoint precision, greatly improving the ability to remove clogged teeth, and remembering the state of your own teeth with your fingertips to take care of weak points.

The toothbrush for oral care of the present invention is shorter than conventional products, so it saves resources, energy, and costs.It can stand on its own, saving space, and if it is separated, it can be easily carried. Reduce plastic waste by half, contribute to SDGs, and protect the global environment in an age-free manner.

(1) Brush part (2) Head part (3) Projection part (4) Handle part

The oral care toothbrush of the present invention includes a brush part (1), a head part (2), a projection part (3), and a handle part (4). The brush portion (1) is a part that is implanted with bristles and comes into contact with the teeth. There are many types of hair bundles with distinctive shapes and materials. The head part (2) preferably has a length of 9 cm and is provided with one or two hemispherical protrusions at the rear of the head part.
The preferred length of the head part is that the hair strands of the head work deeply on the molars, and the cut end of the handle part can be avoided because it is uncomfortable to touch the lips, and contact may lead to dripping in the oral cavity. The size was determined by adjusting the insertion depth of the handle.

The protrusion (3) has one or two hemispherical protrusions and is inscribed in the handle part and plays the role of integrating the toothbrush with strong friction, thereby stably maintaining the insertion depth of the handle part. The protrusion (3) exists as a part that expands the range of motion in the oral cavity, and the fact that there are one or two protrusions plays a role in adjusting the working depth of the brush part in the oral cavity, allowing for shallow and deep tooth brushing. When you use the tube, the tube handle is lifted up by two protrusions that give you a soft, hard, soft, hard, soft feel on the abdomen of your fingertips, and it gently rests on your fingers. Even those who are weak with three fingers can easily carry it around because there is a lot of contact surface between the fingertips. Even if there is only one protrusion, a clue as to whether it is soft, hard, or soft can be obtained from the abdomen of the fingertip. The width of the two protrusions is 22 mm, which is enough to fit one finger.
Therefore, considering the insertion depth of the handle, the length of the head is preferably 9 cm.

The handle part (4) refers to the end of the tube from the brush part side to the opposite end, and has a length of 5 to 6 centimeters with one or two hemispherical protrusions inscribed inside the palm. It is sized to fit in. A resilient tube is inserted from the rear end of the head and functions as a handle. Steering of the handle begins with the thumb and turns using the roundness of the tube. The two fingers (index finger, middle finger) follow the thumb and assist in twisting as a handle while changing the placement of the fingers.
Since the width of the two thick fingers of an adult male exceeds 4 cm, the length of the handle was set to 5 cm or more and 6 cm. By adjusting the insertion depth of the handle, you can choose the position that suits you. The cylindrical handle has just the right amount of elasticity to hold your fingers and does not interfere with the delicate work of your fingertips.

The tube at the handle part has a round shape that projects outward, and the "play" of the air inside the tube due to external pressure can be said to promote twisting, making the handle logical for the toothbrush head to work in all directions and rotate. This is the structure of the department.

In the example, it is made of silicone rubber with an inner diameter of 10 mm and an outer diameter of 13 mm, but it can be expected that new effects will be created by changing the thickness of the tube (2 to 2.5 mm).
