Rotary and reciprocating electronic toothbrush

Abstract

The invention belongs to the technical field of articles for daily use, and relates to a rotary reciprocating electronic toothbrush. The whole toothbrush comprises a protective cap, a toothbrush head, a handle and a base, wherein the bottom end of the handle is inserted in the base in a detachable manner; the upper end of the handle is in detachable sealed butt joint with the toothbrush head; the outside of the toothbrush head is sleeved by the protective cover in a buckling manner; the outside upper and the lower ends of an outer guide ring on the top of the toothbrush head are sleeved by the protective plates; an inner guide ring which is in butt joint with a transmission shaft and a cylindrical rotating brush head are arranged inside the outer guide ring; a sliding clip is fixedly arranged at the inner side of each protective plate; the upper and lower ends of the inner guide ring are sleeved by upper and lower brush heads; a guide rib position is respectively fixedly arranged outside the upper and lower brush heads; the transmission shaft is controlled by a motor to rotate, so that the brush heads are driven to rotate, and the upper and lower brush heads are driven to reciprocate up and down. The electronic toothbrush has the advantages of novel structure, scientific design, high automatic degree, strong tooth cleaning performance, small gum injury, electric and energy saving and environmental friendliness and is convenient to use, and users feel comfortable.

Description

Technical field: [0001] The invention belongs to the technical field of daily necessities, and relates to a rotary and reciprocating electric toothbrush, which is designed according to the shape of human teeth, can clean teeth in all directions without dead ends, and maintain oral hygiene, and is widely applicable to various groups of people. Background technique: [0002] Toothbrush is an inseparable oral hygiene tool in our daily life. The traditional ordinary toothbrush is generally divided into two parts: the handle and the brush head. The shape of the brush head is roughly divided into square and diamond shapes. Or elastic handles, etc. With the development of society, modern toothbrushes generally include three categories: ordinary toothbrushes, electric toothbrushes and ultrasonic toothbrushes.

[0002] Toothbrush is an inseparable oral hygiene tool in our daily life. The traditional ordinary toothbrush is generally divided into two parts: the handle and the brush head. The shape of the brush head is roughly divided into square and diamond shapes. Or elastic handles, etc. With the development of society, modern toothbrushes generally include three categories: ordinary toothbrushes, electric toothbrushes and ultrasonic toothbrushes. Among them, ordinary toothbrushes have a small contact area with the teeth each time when brushing teeth, and the brushing time is relatively long. The large molars in the toothbrush are not easy to clean, and it is easy to cause gum bleeding and other problems when brushing horizontally, and it is not suitable for disabled people, children or mentally handicapped people with inflexible hands; the new ultrasonic toothbrush uses the cavitation effect of ultrasonic energy in the periodontal, In order to remove periodontal bacteria and unclean objects, its cleaning range can cover all parts of the periodontal period, and at the same time, the ultrasonic energy can further penetrate into the inside of the gums by touching the bristles of the gums, which can inhibit gum inflammation and gum bleeding, and prevent gum recession. However, this type of toothbrush is precise in design, complex in structure, and high in cost, and is not suitable for general use by the general public, and it is easy to damage the gums if the frequency is too high if used improperly; Decompose the toothpaste into fine foams to clean the gaps between the teeth deeply. At the same time, the vibration of the bristles can promote the blood circulation in the oral cavity to achieve the effect of massaging the gum tissue. Since its speed and frequency can be adjusted, the speed frequency can be set according to the user's needs to reduce the gums. damage, bring comfort, and have good cleaning ability, and are affirmed by dental experts and favored by consumers

[0003] The brush heads of electric toothbrushes currently on the market have three types of motion: reciprocating linear motion, rotary motion, and both linear and rotary motions. The brush heads of most rotary motion toothbrushes are designed as motor-driven circular single-sided brush heads. Doing high-speed rotary motion, and the bristles are single-head in-line. Under high-frequency vibration, the actual effect of brushing teeth is not much different from that of the reciprocating linear motion brush head. It also cannot clean the molars and teeth deep in the mouth. Gap, for example Chinese patent CN03217031.9 discloses a kind of rotary electric toothbrush, and Chinese patent CN01811858.5 discloses a kind of electric toothbrush with three-dimensional rotating brush head movement, and transmission shaft drives toothbrush end to carry out circular motion, makes bristle carrier Three-dimensional movement; Chinese patent CN97241114.3 discloses a two-way rotary electric toothbrush, the brush head is a cylindrical rotary structure, and has an integrated single-sided shield; the electric toothbrushes disclosed in the above-mentioned patented technologies are all single-head The brush head and single-row bristles have problems such as small cleaning area, low brushing efficiency, and inconvenient use. When using the rotating head, it performs a horizontal brush or rotating friction movement on the tooth surface, which is easy to cause wear and tear on the teeth, and in severe cases, periodontal damage may occur. Therefore, the present invention researches and designs a new type of electric toothbrush with reciprocating upper and lower heads and rotating movement of the central brush head, which can clean all surfaces of teeth at the same time and comprehensively protect oral health.
