Description

A kind of linear actuator, mouth-rinsing device and its control method

Technical field

The invention belongs to household appliance technical fields, especially personal oral hygiene equipment, and in particular to a kind of linear actuator And mouth-rinsing device.

Background technique

Personal mouth washes tool is intended to electronization and intelligence, and the products such as electric toothbrush and water dental floss are more and more People received, the power inside this kind of product is mostly from common direct current generator and electromagnetic high-frequency oscillator etc..

For electronic tooth brush cleaning device, no matter hairbrush is linear reciprocating motion, vibration or rotary motion, required The movement of input and strength are that linear motion and impulsive force need to use crank connecting link if movement is derived from direct current generator Rotary motion is converted linear motion by mechanism；If movement is derived from high-frequency electromagnetic oscillation device, due to the linearity of power output It can be all restricted with the amplitude of movement.

For waterpower crimping cleaning device, the pulse of water jet is generated by plunger pump, and plunger pump is it is desirable that straight line is transported Dynamic and impulsive force mode input, if movement is originated from dc rotating machine, also needing a crank link mechanism will rotate Conversion of motion is linear motion.

Linear motion is converted by rotary motion by crank link mechanism, in addition to because there are nonequilibrium inertia force to lead It causes outside vibration beastly, also generates biggish noise, affect the commodity usability of product.In addition, crank connecting link machine Structure can only export fixed movement travel, and requirement of the user to cleaning often both needs to adjust the frequency of movement in actually using Rate, it is also desirable to adjust the intensity of impulsive force, therefore it is variable can stroke be an important technical indicator, and DC motor structure is very Difficulty reaches this technical indicator.

It is solved the above problems with being difficult appropriate benefit with existing general technology, such as United States Patent (USP) " TUNULAR LINEAR MOTOR " patent No. US9379599B2, it is similar with other general linear motors, provide the circulation of the asynchronous driving of multi-coil Phase high-precision motion scheme, number of coils and number of magnetic poles onrelevant, it is limited with the linear actuator quarter-phase to be executed Trip objective has larger difference.

Problem above is needed by proposing that new technical solution is resolved.

Summary of the invention

The present invention in view of the above-mentioned problems, be designed to provide a kind of linear actuator and a variety of mouth-rinsing device technical sides Case, the actuator can directly provide linear motion, while can adjust motion frequency and amplitude by software, so as to A variety of different mouth washes technical solutions are derived, have the characteristics that small and low noise is moved in damping.

The above problem is solved by the technical solution of following three aspects.

In a first aspect, i.e. a kind of linear actuator, can provide the shaped stator of transverse magnetic field including one, one includes line The armature of circle, the coil encircling stator and the cleavable magnetic line of force simultaneously lead to armature longitudinal movement, a force transmitters, shaped stator It is limited at armature among closed actuator body plenum, force transmitters pass through actuator ontology and electricity in a sealing manner It is pivoted and connects, and linear movement output and impulsive force under the driving of armature；

Wherein, shaped stator includes the permanent magnet longitudinally to magnetize or the iron core of longitudinal excitation, can be in its magnetic pole neighborhood Transverse magnetic field is provided；The coil of armature is arranged in around the magnetic pole, when electric current passes through coil, according to Lorentz (LORENTZ) right-hand rule can generate the longitudinal force for leading to armature movement；

Armature and shaped stator clearance fit, can be in longitudinal a certain range with sliding almost without the formal freedom of mechanical resistance It is dynamic, lubricant grease or other polymeric lubricants can be put into the fit clearance；

Sealing can at least be accomplished by the following way between force transmitters and actuator ontology but do not influence mechanical movement Connection, a kind of preferential mode are as follows: including a diaphragm with inside and outside two closed sides, inner edge connects power transmission in a sealing fashion Device, outside connect actuator ontology in a sealing fashion, with realize the leakproofness of actuator body interior space and exterior space every From the diaphragm can be made of high molecular materials such as rubber；
