Description

The present invention relates to a cylindrical electric toothbrush, a cylindrical water injection toothbrush, and a manufacturing method thereof.

All of the commercially available cylindrical toothbrushes are manually brushed, and there are products with the following brush structure.
First, a desk-shaped ultra-thin brush and a donut-shaped resin material called a spacer are alternately laminated to form a brush part, and a desk-shaped ultra-thin brush welding side is provided with a convex part in advance to form a brush part. There are products that alternately stack desk-like ultrathin brushes and rubber-molded brushes.

  There are no products currently available on the market for cylindrical electric toothbrushes, but there are several documents in the JPO publication that consider the removal of plaque by mechanically rotating the cylindrical toothbrush portion.

  Regarding the water injection toothbrushes, two documents were found in the JPO publications for the purpose of effectively removing plaque by injecting water from the root of the implanted flat toothbrush and assisting care or brushing. . Further, there is a product in the form of Patent Document 1 in a dental tooth cleaning device with a wide range.

  The water injection type oral cleaner currently on the market is a type of product that discharges flowing water from the tip of the curved nozzle hole that has been sold for a long time, and drops plaque on the interdental and tooth surfaces by the flow rate. is there.

Problems to be solved by the inventor

  The feature of the cylindrical toothbrush is that it is easy to brush and can effectively remove plaque. In particular, we want to provide more efficient brushing by making the most of the characteristics of cylindrical toothbrushes to children, people who have some kind of handicap, that is, people who are not good at brushing, and people who finish brushing in a short time. was there.

  Next, for those who have physical disabilities and are unable to brush themselves, it is important in terms of health and devotion to keep the oral cavity clean and clean. For the purpose of reducing this stress, we considered to clean the oral cavity and keep it clean. Conventional cylindrical toothbrushes are products that are suitable for brushing by caregivers because of their shape characteristics. The aim was to develop a product that fully utilizes this form, and obtains a more effective plaque removal effect and exhilaration in the oral cavity.

Means for solving the problem

  For children or people who are not good at brushing, the problem is that the oral cavity can be easily and efficiently cleaned in a short time and plaque can be removed, and the brush portion is mechanically vibrated. In addition, as a means to further improve the plaque removal efficiency of the cylindrical electric toothbrush, there is also a problem of efficiently washing away the plaque cleaned by the brush portion by injecting an appropriate amount of liquid such as water from the inside of the brush. It was considered as one of the means to solve the problem.

  For those who need nursing care, a manual cylinder that supplies water, such as water, to the main body tank part, passes a soft small-diameter water pipe from the main body motor part, and advances brushing while injecting an appropriate amount of liquid, such as water, from the inner surface of the cylindrical brush. A mold watering toothbrush was manufactured. This toothbrush has a structure that allows the caregiver to easily adjust the amount of water and turn it on and off, and manufactured a one-point brush type and a small-diameter rubber-molded cylindrical brush shape according to the shape of the oral cavity and teeth.

The invention's effect

  A vibration type electric toothbrush was developed by paying attention to the number of brushes, which is the biggest feature of cylindrical toothbrushes. The electric toothbrush with the maximum frequency currently on the market is about 31,000 times per minute by ultrasonic vibration. However, the number of brushes that transmit the vibration to the tooth surface and remove plaque is about 1,000 because of the flat planting type, and the number of times that the plaque is simply scraped by vibration is about 31,000,000 per minute. . On the other hand, the number of brushes in a cylindrical toothbrush is about 10,000, and if the same frequency is used, plaque removal can be performed almost 10 times more efficiently than a conventional plain plant type electric toothbrush. Further, even if the vibration source is changed from an ultrasonic wave to a motor, the vibration frequency is increased by several steps compared to the electric toothbrushes currently on the market. The numerical value is about 9,000 per minute. When the number of brushes is about 10,000, the numerical value is about 90,000,000, and an electric toothbrush with low price and high plaque removal efficiency can be provided.

  In addition, since it is cylindrical and electrically powered, it can be easily used by children and people who are not good at brushing, and can remove plaque efficiently. In addition, brushing on the back side of the tooth surface is easier than conventional manual cylindrical toothbrushes.

  The type of brush that injects water from the brush inner surface in the electric vibration type tooth cleaning device is a technique that is used only for a dental handpiece, and the cleaning efficiency between the tooth surface and the teeth is high. By applying this technology to commonly used electric toothbrushes, the ability to remove plaque was significantly higher.

  When brushing care recipients, face the upper body in a lying position, and proceed with brushing with the water receptacle placed under the face and the mouth open. In this case, in order to prevent accidental ingestion, it is possible to proceed safely by reducing the amount of water injected from the inside of the brush to a minute amount (about 200 milliliters by brushing for 5 minutes). In addition, the caregiver can change and use the brush with a single touch according to the shape of the oral cavity, and the amount of water injection can be easily changed at hand, improving work efficiency.

  Next, the best mode for carrying out the invention will be described with reference to the drawings. FIG. 1 shows the entire cylindrical electric toothbrush. The structure includes a cylindrical brush 1, a neck 2, a neck replacement portion 2 a, a main body portion 3, and a switch 4. The most important brush 1 has a shape made of one solid and the following four methods.

  First, there is a method shown in FIG. The cylindrical brush 1 is manufactured by laminating an appropriate amount of a round brush element small hole 1c located at the center of the round brush element welding part 1b in the round brush element 1a in the round brush element insertion part 2b located at the tip of the neck 2.

  Next, the method of manufacturing the cylindrical brush 1 by inserting the spacer 2c between the round brush elements 1a in FIG. 3 is shown in FIG. 4, and the rubber molded brush element 5 in the center of the round brush element 1a in FIG. The cylindrical brush 1 was manufactured by inserting the rubber molding brush element small holes 5a positioned therein. In addition, there is also a method for producing a cylindrical brush 1 having a space by providing a convex portion on the side surface of the round brush element welded portion 1b in the round brush element 1a.

  In the cylindrical electric toothbrush shown in FIG. 1, a cylindrical electric water injection toothbrush structure capable of simultaneously injecting water will be described with reference to FIG. In addition to the cylindrical electric toothbrushes 1 to 4 shown in FIG. 1, the internal structure is such that a vibration generating motor 6 and a motor shaft 6a coupled thereto are provided near the center of the main body 3 and a power source 7 is provided at the rear thereof. The water pipe 8 for water injection passes through the inside of the main body 3 and the outside and the inside of the round brush element insertion portion 2b in the cylindrical brush 1 is hollow, and an appropriate amount is injected from the water pipe water injection hole 8a. The size and number of the water pipe injection holes 8a vary depending on the purpose of use, but the diameter is about 0.3 to 0.6 mm, and the number is considered to be about 10 to 30 between the brush lengths of 16 mm. For general use, the amount of water used should be approximately 400 milliliters for 5 minutes of brushing and 200 milliliters for nursing care. In addition, the water pipe 8 is connected to the water tank main body 12 by a joint 9 at the rear end of the main body 3 to pour water.
