Description

Automatic Teeth Brush {Automatic teethbrush}

The present invention relates to an automatic toothbrush used when cleaning teeth, and more particularly, to an automatic toothbrush that can use the existing toothbrush.

Teeth mechanically break or grind food when ingesting food. This action helps digestion by allowing food to mix well with digestive fluids. In addition, teeth can have a chewing sensation, which makes them feel and eat when eating. Obtaining nutrients from the outside by eating food is a basic action for human survival, so the health of teeth involved in the action has a great impact on the health of the human body.

If food remains between teeth and decays, the teeth are damaged by substances caused by food or bacteria, causing bad smell, which can cause you to feel bad and disgust others. Furthermore, if the erosion of the teeth is intensified, some of the teeth are removed or damaged as a result of the damage, and even if the gums that fix the teeth to the human body are removed by the action of bacteria, the teeth are pulled out and the nerves are irritated and painful. Negative effects on nerves can damage your health.

Therefore, human beings have developed many methods for cleaning teeth for the health of teeth since ancient times. The most common method of cleaning teeth at present is brushing teeth using a toothbrush. Toothbrush is made by installing elastic and strong bristles on the tip of the rod-shaped toothbrush rod to clean the teeth in the mouth. Brushing teeth is rubbed on the teeth and gums by applying a sterilizing or abrasive material. Done.

As a lot of systematic researches on the health of teeth, many researches on these toothbrushes have been made, and many proposals have been made on the shape of the toothbrush, the material form of the brush head, and the brushing method.

One of them is the automatic toothbrush. The automatic toothbrush does not need to brush your teeth while moving the toothbrush. If you touch the brush head to the brushed area, the brush head rotates or vibrates to clean the tooth. Therefore, the automatic toothbrush is particularly suitable as a toothbrush for infants, the elderly, or a patient toothbrush.In case of tiredness, the toothbrush is cumbersome and it may be inconvenient for the toothbrush to be damaged in the oral cavity due to the excessive force and rush to brush the teeth in busy morning hours. Can also be used conveniently.

The automatic toothbrush is mainly made of electricity as a power source, and the small toothed motor is used to rotate or mechanically reciprocate the part where the brush head is installed. Therefore, holding the automatic toothbrush by hand and brushing the part with the bristles to brush the toothbrush rotates or vibrates up and down or from side to side to wipe between the tooth surface and teeth.

In the case of the existing automatic toothbrush, the handle portion of the toothbrush rod and the brush head installed portion are prefabricated, so that when the brush head is old, it can be replaced. However, in the case of the current automatic toothbrush, it is dealing with a considerable price. In general, even when the handle part and the brush head part are prefabricated, they are connected in a close structure, close to all, so that each manufacturer and product are not compatible with each other. There was a lot of inconvenience in replacement, such as finding a dealer of the manufacturer.

In addition, the existing automatic toothbrushes are quite expensive, so when all the members of the family purchase the automatic toothbrushes, the cost is not small, and in spite of their convenience, they were often not used.

The present invention has many problems such as the automatic toothbrush has different specifications for each manufacturer or product, and it is very inconvenient to replace the toothbrush. The purpose is to provide an automatic toothbrush that can be used.

The automatic toothbrush of the present invention for achieving the above object is made with a container-type body, the toothbrush mounting portion to which the toothbrush is fitted, the driving unit to operate the toothbrush attachment portion to brush the teeth and the power supply for supplying energy to the drive unit The toothbrush attachment part may include a fixing part and an operation part contacting the driving part so as to receive the movement of the driving part so as to fix the existing rod-shaped toothbrush.

In the present invention, the toothbrush attachment portion is provided with a fixed portion of the structure that can fix the handle portion of the general rod-type toothbrush, and the operation portion in contact with the drive portion to receive the movement of the drive portion is made integrally connected. Therefore, when the operating part in contact with the drive is moved under the influence of the drive unit, the fixed part moves the toothbrush fixed state so that the brush head in contact with the teeth to brush the teeth.

Figure 1 is a schematic diagram showing the appearance of the toothbrush inserted into the present invention automatic toothbrush. A fixing screw 13 is shown on the toothbrush fixing frame 12 that is the upper part of the container-shaped body 11 of the automatic toothbrush 10 to fix the toothbrush 1 to the outside, and a speed control switch 14 is installed below the toothbrush fixing frame 12. have.

The fixing part may be manufactured in a container shape in which the toothbrush can be fitted. By the way, in the case of the container type, the toothbrush of various types and sizes should be fitted to the fixing device of the present invention, so that the container is formed to have enough space to fit all of the general toothbrush. However, in this form, it will be difficult to fix the toothbrush, so install one or more fixing screw screws through the container forming the fixing part on the outer wall of the container body, insert the toothbrush into the container, and then tighten the screw screws to fix the toothbrush rod. The toothbrush can be fixed in the form.

2 is a cross-sectional view showing the internal configuration of an embodiment of the present invention automatic toothbrush is composed of a toothbrush fixing portion 21 comprises a container including a toothbrush 1 and a toothbrush fixing screw 13 installed from the outside of the container. . The fixed part is connected to the inverted Y-shaped moving part. The driving device is an example in which the cam 25 provided on the motor 23 and the motor shaft 24 is used.

In addition to the fixing screw, a wedge may be used. In the wedge method, a slightly elastic wedge-shaped fitting is connected to the lever with a shaft, and when the lever is turned, the fitting is fitted like a wedge between the container and the toothbrush.

In addition, a variety of toothbrush fixing devices are possible by adopting many types of levers using elastic members and levers.

In the present invention, as a driving unit, a driving motor and an electric vibrator connected to the power source may be considered first. There may be various ways to move the toothbrush attachment part which fixes the toothbrush using a drive motor, but it can be considered simply how to use the cam 25 as shown in FIG. When the drive motor 23 connected to the power source rotates, the cam connected to the motor shaft 24 rotates, and when the protrusion of the cam comes into contact with the connection branch 26 formed downward from the upside down Y-shaped connection part, it is pushed outward from the center. give. Then, the connecting portion is installed to be rotated about the shaft 27, so that when the branch 26 of the connecting portion is moved outward, the central stem 28 opposite the shaft 27 comes into contact with the branch 29 of the operating portion. At this time, by the action of the shaft 27, the central stem 28 pushes the operation branch 29 to the other outward.

These operation part branches 29 are connected with the container type fixing part 21 of the toothbrush attachment part to which the toothbrush was fixed. And the central portion connected to the toothbrush attachment portion 30 to secure the toothbrush attachment portion to the fixed frame of the automatic toothbrush container type body and the toothbrush attachment portion is formed so as to be able to rotate at a certain angle around the axis. As a result, when the long radius portion of the cam 25 pushes the connection part branch 26, the connection center stem 28 moves the operation part branch 29 and moves the toothbrush 1 of the fixed part connected to the operation part.

In addition, if a spring device such as a leaf spring is installed in the moving path of the branch of the connection part or the moving part, and the convex part of the leaf spring comes into contact with the branch part, the concave leaf spring becomes convex again after the long radius of the cam passes. Will restore the original position. Since two branch parts are formed at each of the connecting part and the operating part, the toothbrush moves to the left and the right once when the cam is rotated once. To speed up the movement of the toothbrush, use a triangular cam with a long radius on the cam, a pentagonal cam, etc., or increase the rotation speed of the motor with the cam installed.

The case of using the electric vibrator is shown in FIG. The most basic form of an electric vibrator is that seen in an electric bell. As shown in Fig. 2, there is an operation part having a branch 29, and the branch part of the operating part is formed to have a slightly collected tip. The drive section includes an inverted Y-shaped connecting section, an electromagnet section 31, and an attached electric circuit. At this time, the end of the central stem 28 of the Y-shaped connecting portion is located between the branch portions collected from each other of the operation portion, the branch 26 portion of the connecting portion is a magnetic material, and each of the electromagnets on both sides of the inner wall of the main body of the automatic toothbrush The part 31 is formed. A shaft 27 is formed between the central stem 28 and the branch portion 26 of the connecting portion, similar to the shaft 30 between the container-type fixing portion 21 and the operating portion of the toothbrush attachment portion. When the electromagnet part is separated from the branch part 26 adjacent to the neighboring part by more than a certain distance, electricity flows to become an electromagnet, which pulls the branch part of the connecting part, and when touched, the electric current is cut off by a coil that applies a magnetic field to the electromagnet to lose its properties. While the power is supplied from the power supply unit, the branch 26 portion of the connection portion is separated from the neighboring electromagnet portion 31 and continues to attach. As this pattern is repeated, the branch part of the connection part continuously vibrates from side to side, and the central part of the connection part 28 pushes the branch part 29 of the operation part of the toothbrush part to the left and thus the axis 30 to which the toothbrush part is rotatably fixed. ) Move the toothbrush fixed to the container type fixing part 21 on the opposite side to the left and right. The electromagnet can then use a relay circuit in addition to the mechanical switch action associated with the connection.

The power supply unit may include an external power supply type that draws in electricity from outside and operate a driving motor or an electric vibration device, and an internal power supply type using a battery or a storage battery. The external power type may be divided into a DC power type or an AC power type, and may be installed as an internal power type using a battery or a battery to be suitable for portable use.

It may be convenient to use a regulator to control the speed of the toothbrush as necessary by increasing the number of rotations of the driving motor by increasing the amount of current in the power circuit or increasing the frequency of the vibration device. The number of reciprocating movements or the frequency of the toothbrush is suitable from 3 to 5 to 7 times a second, and the speed of the brushing is also preferably used to be divided into three times, five times, seven times through the switch. In addition, the range of movement of the brush head to clean the teeth also adjusts the position of the shaft, the length of the connection portion, the degree of opening of the body or branch of the toothbrush body, the long radius of the cap, and the vibration width of the vibrator so that the size of the upper and lower teeth is combined. And it is preferable to form so that the width can be finely adjusted.

Automatic toothbrush The toothbrush attachment part is exposed to external moisture as the toothbrush is fixed, which may cause an electric leakage to the internal electric device and in some cases, the user may receive an electric shock, so install the power supply part or the driving part to cover the gap well with waterproof material. It is preferable to form the material of the synthetic resin that does not pass through electricity because it is inevitably in contact with water.

Using the automatic toothbrush according to the present invention can save the user the trouble of brushing. In addition, the existing manual toothbrush can be used and the toothbrush can be easily replaced, so if one automatic toothbrush is provided, it can be used by many people, and the cheaper manual toothbrush can be reduced by reducing the cost and effort of replacing the existing automatic toothbrush. Can be used.

Although specific embodiments of the present invention have been mainly described above, it will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the present invention, and such modifications and modifications belong to the appended claims.
