Description of the invention (1) Background of the invention (please read the notes on the back before filling this page) This case is the US Patent Application No. 09/3 82,745 filed on August 25, 999 Partial serial case, the latter is the application serial number 09 / 236,794 filed on January 25, 1999, and the latter is the application serial number 09 1 63 62, filed on September 30, 998 No. 1 was announced on December 14, 1999 as part of a serial case of US Patent No. 6,000,983. The invention relates to an electric toothbrush. More specifically, the present invention relates to a novel battery-powered toothbrush. The benefits of using an electric toothbrush to brush your teeth are well known, and the electric movement of a toothbrush has been the subject of many recent technological innovations and design activities. And, in recent years, many different types of electric toothbrushes have been introduced into the commercial market. Examining existing technologies, however, has shown a tendency towards increasingly complex, expensive, and non-commercially feasible methods to achieve electric movement of the bristles and head of a toothbrush to assist in more effective cleaning of teeth. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The commercial market has been divided into two price markets. At the higher end are some more sophisticated electric toothbrushes that provide a variety of different movements to the bristles and toothbrush head. The lower end of the market becomes a very simple range of electric toothbrushes that vibrates only by using an offset weight attached to the motor shaft, and its use provides very little real additional cleaning benefit because there is no Powerful movement is transmitted to the clean surface of the toothbrush. Vibrations are also very uncomfortable for the hands and become a hindrance to brushing the toothbrush for an appropriate period of time. Many electric toothbrushes have been developed over the years. Some known devices are shown in U.S. Patent No. 5,070,567 and U.S. Patent No. 5, 1 86,627. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 1-4-495359 A7 B7 V. Invention Explanation (2) (Please read the notes on the back before filling this page), US Patent No. 5,274,870, US Patent No. 5,341,534, US Patent No. 5,378,153, and US Patent No. 5,732,433 No. The present invention intends to provide a low-cost, effective, ergonomically correct electric toothbrush, wherein the toothbrush includes a moving circular toothbrush portion and a fixed toothbrush portion. Therefore, it has been considered desirable to develop innovative electric toothbrushes that can overcome the above and other problems while providing better and more favorable overall results. The invention relates to an electric toothbrush. More specifically, this electric toothbrush uses electric movement. It is used for personal hygiene to clean teeth and gums. In a first preferred embodiment, the electric toothbrush includes an elongated body portion, a toothbrush head attached to a first end portion of the elongated body portion, and a handle attached to a second end portion of the elongated body portion. And an oblique axis between the toothbrush head and the handle. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The toothbrush head contains a longitudinal axis, a circular or moving part, and a static part. The moving part rotates, rotates, orbits, swings, or reciprocates about an axis perpendicular to the longitudinal axis of the toothbrush head, and is incorporated into the larger toothbrush head. The static part contains static bristles on the opposite side of the moving part. The hard bristles of the moving part can be slightly recessed in height from the height of the static bristles. This particular configuration allows the stationary, static bristles to be typically composed of softer bristles so as not to damage the gums, and the moving part contains hard bristles that facilitate deep cleaning and pathogen removal. Static This paper size applies the Chinese National Standard (CNS) A4 specification (21 × 297 mm) -5- 495359 A7 B7 V. Description of the invention (3) The part and the moving part can also include the massage tip with the bristles. (Please read the precautions on the back before filling this page.) The toothbrush head has a larger traditional head shape, which allows the user to clean the electric moving part of the toothbrush head more effectively. Brush your teeth up and down. The design of the toothbrush head allows it to be manufactured cheaply and brings an effective electric toothbrush within the economic capabilities of most of the population. The oblique axis provides ergonomic benefits that are not used in electric toothbrush on. The well-known ergonomic benefit of this angle is to allow easier access to the rear recess of the oral cavity while still touching the surface of the teeth. The elongated body portion includes a hollow portion. The toothbrush additionally contains a motor in a hollow portion of the elongated body portion. The motor is operatively connected to the moving part of the toothbrush head, and is used to rotate, swing, or reciprocate the movable bristles on the head. The motor has a longitudinal axis that is coaxial with the longitudinal axis of the elongated body portion. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The hollow section additionally contains a simplified gear assembly. The gear assembly may include any one of several embodiments. In one embodiment, the gear assembly includes a worm gear, two step gears, and a shaft. The motor is operatively connected to the worm gear. The step gear is operatively connected to the worm gear and is connected to each other. The gear assembly delivers sufficient torque and speed while maintaining battery life. The first stepping gear allows the second meshing stepping gear to be offset with respect to the longitudinal axis of the elongated body portion and placed at a desired angle, so that the shaft itself can still be straight and therefore not subject to additional friction by the flexible shaft And lose any power or torque. The shaft is operatively connected to the offset stepping gear at the first end and operatively connected to the moving portion of the toothbrush head at the second end. This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 mm) -6-495359 A7 _B7__ V. Description of the invention (4) (Please read the precautions on the back before filling this page) The operation of the unit also includes permissible units A switch. The switch includes an actuator button and a metal contact. The switch is manually depressed by pressing a molded actuator button, wherein the molded actuator button is pressed against a metal contact, thereby completing the circuit, as in a conventional momentary switch. The switch is designed with a bevel to allow continuous operation by pressing the actuator button down and sliding forward, as in a conventional continuous switch. The forward movement combined with the moulded-in-place ramp causes the actuator button to move down, pressing against the metal contacts, thus completing the circuit. By combining these two functions in one switch, a consumer can try out this unit to see its operation before purchasing, and still be able to operate continuously after taking it out of the package. This electric toothbrush may additionally include a battery located in a hollow portion of the elongated body portion. A slidable snap cover is depressed and then released from the end of the handle, thereby opening to expose the hollow portion. The battery is then inserted and the cover is slid in and snaps into place. Printed by the Ministry of Economic Affairs Intellectual Property ¾ Employee Consumer Cooperative In a second preferred embodiment, the electric toothbrush includes an elongated body portion, a toothbrush head attached to the first end of the elongated body portion, attached to the elongated body A handle at the second end of the portion, and an oblique axis between the toothbrush head and the handle. The toothbrush head includes a longitudinal axis, a circular or moving portion, a static portion, a first end portion, and a second end portion. The position of the first end portion of the head is adjacent to the first end portion of the elongated body portion, and the position of the second end portion is opposite to the first end portion. The static part is located at the first end or the second end of the head. The moving part is located at the opposite end of the head. The moving part can be rotated and rotated about an axis substantially perpendicular to the longitudinal axis of the toothbrush head.
