Rotary-vibration electric nursing device

Abstract

The invention discloses a rotary-vibration electric nursing device. The rotary-vibration electric nursing device comprises a handle and a nursing head, wherein the handle is provided with a hollow cavity; the nursing head is inserted in one end of the handle; an eccentric bearing and a double flexible swinging arm rotary mechanism are driven through a motor; the double flexible swinging arm rotary mechanism is connected with a nursing head revolving shaft; the nursing head revolving shaft extends out of the handle; the nursing head is connected with a tail end of the nursing head revolving shaft. The rotary-vibration electric nursing device is driven by a high-frequency motor, and the motor is used for inputting and outputting the same high-frequency rotation and double-frequency vibration in a way of rotating by 360 degrees; the rotary-vibration electric nursing device has the advantages of small amplitude, low noise, large transmission ratio, high strength, and realization of effective cleaning, massaging and health care on the teeth and face of a user; moreover, the rotary-vibration electric nursing device has the advantages of less accessories, easiness in assembling, and lower manufacturing and production cost.

Description

technical field [0001] The invention relates to the technical fields of tooth cleaning, beauty care and health care, in particular to a high-frequency micro-amplitude flexible constant force rotary vibration electric care device. Background technique [0002] At present, electric toothbrushes have the function of automatically cleaning teeth and have a good cleaning effect, and are more and more popular among consumers; however, current electric toothbrushes generally include a handle with a hollow cavity and a handle inserted at one end of the handle. The brush head, the battery and the high-frequency vibration device electrically connected to the battery are installed in the hollow cavity. The high-frequency vibration device drives the brush head to brush teeth. It is called a sonic toothbrush.

Problems solved by technology

[0002] At present, electric toothbrushes have the function of automatically cleaning teeth and have a good cleaning effect, and are more and more favored by consumers; however, current electric toothbrushes generally include a handle with a hollow cavity and a handle inserted at one end of the handle. The brush head is equipped with a battery and a high-frequency vibration device electrically connected to the battery in the hollow cavity. The high-frequency vibration device drives the brush head to brush teeth, which is called a sonic toothbrush. However, although a sonic toothbrush has a high frequency, its amplitude is small , the power is weak, the speed of the bristles drops sharply after brushing the teeth, and the teeth cannot be cleaned well; the battery and the low-frequency rotating device connected to the battery are installed in the hollow cavity, and the brush head is driven by the low-frequency rotating device to brush teeth. Rotary Electric Toothbrush

Although the rotary electric toothbrush has a large rotation range, the frequency is low and the force is weak. After brushing the teeth, the speed of the bristles drops sharply.
