Description
Technical field
The utility model relates to a kind of driving assembly of reciprocating electric razor, belongs to reciprocating electric razor technical field.
Background technology
In existing electric shaver industry, driven element is one of topmost part assembly, and its Main Function is for driving cutter head and power to transmit, simple in structure, power transmits directly, all with driven element material major part, take POM, PA66 as main at present, belongs to and is rigidly connected.In shaver industry, be usually used in hilted broadsword head, two cutter heads, on the shaver of three cutter heads. at present driven element is under the rotation of motor and rotate, and the driving turning by bias realizes driven element linear reciprocating motion, driven element band dynamic cutter head linear reciprocating motion, thus reach the object of shaving except beard.But between driven element and eccentric wheel, be hard connection, because bias has centrifugal force, produce vibration, thereby cause whole shaver also to produce vibration, while shaving like this because vibration brings the bad experience of shaving to consumer.
Summary of the invention
The utility model technical issues that need to address are, existing electric shaver, and the effect due to centrifugal force between driven element and eccentric wheel produces vibration, thereby causes whole shaver also to produce vibration, to consumer, brings the bad experience of shaving.
The structure of reciprocating razor is motor driving eccentric wheel at present, changes linear reciprocating motion from rotatablely moving into, because eccentric wheel produces centrifugal force, thereby produces vibration.Eccentric wheel drives driven element, driven element band dynamic cutter head, because eccentric wheel produces vibration, driven element also can produce vibration, cutter head and also can produce vibration, in order to reduce or to eliminate body vibration, the utility model just improves the concrete structure of driven element assembly and assembly relation.
The utility model is taked following technical scheme:
A driving assembly for reciprocating electric razor, comprises motor 5, eccentric wheel 4, actuating arm 3, driven element 2, cutter head 1; The output shaft of described motor 5 makes progress and is connected with eccentric wheel 4, and described eccentric wheel 4 tops connect actuating arms 3, and described actuating arm 3 is done straight reciprocating motion with the rotation of eccentric wheel 4; Described driven element 2 is fixedly connected with actuating arm 3, and does straight reciprocating motion with actuating arm 3; Described cutter head 1 is fixedly connected with driven element 2, and does straight reciprocating motion with driven element 2; Described driven element 2 comprises body 2b and a pair of buffer arm 2a, and described buffer arm 2a adopts thermoplastic elastomer (TPE) TPE material, and with body 2b integrated through injection molding.
The utility model is mainly to the improvement that drives the structure of the driven element in assembly to carry out, the both sides of driven element body arrange buffer arm, buffer arm adopts thermoplastic elastic material, and with driven element body integrated through injection molding, because buffer arm self has certain elasticity, therefore when driven element is done linear reciprocating motion under the drive of eccentric wheel and actuating arm, buffer arm utilizes the elasticity of self material to play the effect of bumper and absorbing shock, thereby reduce the vibration of shaver integral body, improve the comfort level that user shaves and experiences.
Further, also comprise motor base station 7, described driven element 2 is fixed on motor base station 7, and described motor base station 7 is fixed on the housing of electric shaver.
Further, described driven element 2 is fixed on the housing of electric shaver.
Further, the width of described buffer arm 2a is 2-3mm.
The beneficial effects of the utility model are:
1) greatly reduce the vibration of driven element and shaver integral body, promote the comfort level that user shaves.
2) driven element adopts two parts different materials integrated through injection molding, simple for structure, and good reliability.
3) shaver vibration reduces the also lifting greatly of rear reliability.

In figure, 1. cutter head, 2. driven element, 3. actuating arm, 4. eccentric wheel, 5. motor, 6. housing, 7. motor base station, 2a. buffer arm, the body of 2b. driven element.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
Referring to Fig. 1, a kind of driving assembly of reciprocating electric razor, comprises motor 5, eccentric wheel 4, actuating arm 3, driven element 2, cutter head 1; The output shaft of described motor 5 makes progress and is connected with eccentric wheel 4, and described eccentric wheel 4 tops connect actuating arms 3, and described actuating arm 3 is done straight reciprocating motion with the rotation of eccentric wheel 4; Described driven element 2 is fixedly connected with actuating arm 3, and does straight reciprocating motion with actuating arm 3; Described cutter head 1 is fixedly connected with driven element 2, and does straight reciprocating motion with driven element 2; Described driven element 2 comprises body 2b and a pair of buffer arm 2a, and described buffer arm 2a adopts thermoplastic elastomer (TPE) TPE material, and with body 2b integrated through injection molding.
Also comprise motor base station 7, described driven element 2 is fixed on motor base station 7, and described motor base station 7 is fixed on the housing of electric shaver.
Described driven element 2 is fixed on the housing of electric shaver, and structure is more simplified.
The width of described buffer arm 2a is 2-3mm.
The present embodiment is for solving shaver vibration problem, this patent improves the structure of driven element, make full use of thermoplastic elastomer (TPE) TPE feature: a kind of high resiliency with rubber, high strength, high resilience, has again the material of feature that can injection molding, has both had the processing characteristics of thermoplastic, the physical property again with vulcanized rubber is the advantage combination of plastics and rubber advantage.Because TPE has high resiliency, high strength, the feature of high resilience, can reduce or eliminate the effect of vibration, make full use of this feature, driven element structural design is to the combination of body and buffer arm, body is that TPE material structure, buffer arm are previous thermoplastic materials (POM, PAA66) structure.Like this, be with movable eccentric wheel, eccentric wheel to drive driven element after motor starting, because current driven element is through improving structure for being partly that TPE material, part are thermoplastic, TPE partial structure will reduce or eliminate the vibration that eccentric wheel centrifugal force produces.Thereby solve above-mentioned required electric shaver vibration problem.
