Micro facial massager
View Patent ↗A micro facial massager includes a housing, a circuit board, a driving motor, an eccentric wheel arranged on an output shaft of the driving motor, a massage piece, batteries received by a battery box which is positioned in a placed groove. A through hole is defined in a bottom of the placed groove. The battery box is dismountable and is insertable into the housing. The micro facial massager further includes two metal connectors, where the two metal connectors are corresponding fixed in the housing and are connected with the circuit board. When the battery box is inserted into the housing, the two metal connectors press an anode and a cathode of the battery, respectively. Thus, it is convenient to only open the battery box to replace the batteries.
1. A micro facial massager, comprising:
a housing;
a circuit board;
a driving motor;
an eccentric wheel arranged on an output shaft of the driving motor;
a massage piece;
at least one battery positioned in a placed groove of a battery box;
two metal connectors; and
wherein a through hole is defined in a bottom of the placed groove; the battery box is dismountable and is insertable into the housing; the two metal connectors are corresponding fixed in the housing and are connected with the circuit board; the two metal connectors press an anode and a cathode of the at least one battery when the battery box is inserted into the housing, respectively;
two supporting structures are formed on a first side of the housing to hold up the battery box, and two sliding structures are formed on two sides of the battery box to engage with the two supporting structures, respectively; a clamp is formed on a top end of each of the two sliding structures, a stuck column is formed on a front end of each of the two supporting structures to engage with the clamp.
2. The micro facial massager of claim 1 , wherein the two supporting structures are symmetrical.
3. The micro facial massager of claim 1 , wherein thickness of the clamp gradually increases from a top of the clamp until the thickness of the clamp has no change and the stuck column is a circular structure.
4. The micro facial massager of claim 1 , wherein an opening is arranged between the two sliding structures.
5. The micro facial massager of claim 4 , wherein the placed groove is formed by a convex edge of the battery box, and the convex edge is an arc-shaped structure; a plurality of reinforcing ribs are uniformly arranged in a middle part of the convex edge; a height at connecting end of the reinforcing ribs is equal to a height of the convex edge, and gradually decreases toward an opposite end of each of the reinforcing ribs.
6. The micro facial massager of claim 1 , wherein a contact part of the metal connector contacted with the battery is an arched structure: a folded-over is arranged in a front end of the contact part metal connector.
7. The micro facial massager of claim 6 , wherein a first end of the metal connector defines a hot-melt hole, the housing includes a hot-melt column, and a connecting end is formed in the first end of the metal connector.
8. The micro facial massager of claim 7 , wherein a recess is arranged on a position connecting the housing and the battery box.
