Description

Portable bionic massager structure

Technical Field

The invention relates to a massage health-care product, in particular to an internal transmission mechanism of the massage health-care product.

Background

The massage is gradually summarized, recognized and developed by people working in our country in the long-term struggle with diseases, the pursuit of people for natural therapy is obviously increased along with the high-speed development of the society and the transformation of medical modes, and the development of the massage appliance industry is rapid. In the 80 s of the last century, the massage apparatus has developed into a huge industrial chain integrating design, production, sale and service in China through decades of development, and China has reached the international leading level in the aspect of the massage apparatus.

Among the massage apparatuses, the portable massage apparatus occupies a large proportion of the market. The portable massage instruments have different sizes, and are small and medium; the power sources of the products are all motors, the power supply modes are different, and an undetachable lithium battery, a No. 5 rechargeable battery, alternating current direct supply and the like are mainstream modes; the massage head position contacting with human body has single head, double head, three head and four head designs. Although the portable massage instruments are various in appearance, the essence of the portable massage instruments is that power is transmitted to the massage head part through a direct current brush motor and a transmission device, most of the existing portable massage instruments on the market realize the massage function through the vibration of the massage head, the vibration mode is caused by an eccentric wheel, and a plane rotating reciprocating mechanism enables the massage head to rotate in a plane in a certain rule.

The portable massage instruments on the market at present have the following problems due to the limitations of transmission performance and working principle. The eccentric wheel vibration type power transmission system achieves the effect of massage maintenance by causing the vibration of the massage head through the high-speed rotation of the eccentric wheel, but the design takes the integral vibration as output, so the noise and the vibration of the whole machine are large, the user experience is poor, in addition, the long-term high-frequency vibration also has great influence on the strength of the product parts, but because the strength of the massage head is strong, a plurality of portable massage instruments still use the design; the plane reciprocating mechanism type products mostly adopt double-head or four-head massage heads, the scheme is relatively stable in operation compared with an eccentric wheel vibration scheme, and noise is reduced, but the massage heads have low motion frequency in a horizontal or vertical plane, and massage force hardly achieves expected effects, and the expected effects of relieving pain, promoting blood circulation to remove blood stasis and the like cannot be achieved.

Aiming at the problems of user operation experience and use effect, a portable bionic massager structure is disclosed.

As a further improvement of the invention, the two cams are arranged oppositely, the farthest point and the nearest point of the two cams are arranged oppositely, and the two independent massage head bases realize the opposite movement.

As a further improvement of the invention, the number of the reset springs is four, the number of the massage head bases is two, and the number of the massage heads is four.

As a further improvement of the invention, the motor also comprises a battery which provides power for the motor.

As a further improvement of the invention, the battery is a rechargeable battery.

The invention has the beneficial effects that:

compared with the original eccentric vibration scheme, the novel transmission mode is adopted, high-frequency vibration is avoided, noise and vibration are obviously improved, and active use experience of a user is improved;

compared with the traditional reciprocating structure, the power transmission is more direct, the touch feeling is stronger, and the massage effect is improved;

acceleration, maintenance and slowing of the impact process can be realized through the outer contour of the cam, four-head double-row cyclic impact is innovated, and bionic massage is further realized;

the whole machine has small volume and convenient carrying, storage and use.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

A portable bionic massage instrument structure comprises a shell 1, a return spring 2, a battery 3, a cam shaft 4, a cam 5, a massage head base 6, a massage head 7, a driven gear 8, a driving gear 9, a gear shaft 10, a coupler 11 and a motor 12.

The motor 12 drives the driving gear 9 through the coupler 11 and the gear shaft 10, the driving gear 9 drives the driven gear 8 to rotate in a vertical plane, the driven gear 8 is sleeved on the camshaft 4, the driven gear 8 drives the camshaft 4 to rotate, and the cam 5 is sleeved on the camshaft 4 and rotates together with the camshaft 4;

one end of a reset spring 2 is connected with the shell 1, the other end of the reset spring is connected with a massage head base 6, a cam 5 is contacted with the massage head base 6, the cam 5 rotates to drive the massage head base 6 to move, a massage head 7 is connected with the massage head base 6, the massage head 7 moves along with the massage head base 6, and the reset spring 2 enables the massage head base 6 to reset smoothly after reaching the lowest point.

This portable bionic massage appearance of this section uses battery 3 as the power source, and battery 3 preferred is rechargeable battery. The power is output by the motor 12, and the power transmission direction is changed through the gear transmission set, namely, the power transmission direction is changed through the coupler 11, the gear shaft 10, the driving gear 9 and the driven gear 8. The power is transmitted to the cam shaft 4 to drive the cam 5 to rotate, the farthest point and the nearest point of the two cams are reversely arranged, and the power is transmitted to the massage head base 6 through the cam to drive the massage head 7 to work, so that the human body is massaged.
