The small (palm-on) massager structure currently on the market, such as the Republic of China Patent Publication No. M446632 "Massage Device Improved Structure", is provided with an upper sleeve inside an outer casing, and the upper sleeve is provided with a coil wound around it. An electromagnetic element is formed on the peripheral side of a central catheter. A drive element group has a drive column that extends into the central catheter and is driven by electromagnetic waves. One end of the drive column is connected to a fitting piece, and the other end of the drive column can be fitted through an upper connecting rod. After a spring, it is fixed on the end of the upper link with a stopper. A transmission element has a lower sleeve connected to the upper sleeve. The lower sleeve has a central hole for accommodating the sleeve and a transmission column One end extends into the central hole to collide with the sleeve. The middle section of the transmission column is recessed with an axially extending guide groove, and on the peripheral side of the lower sleeve is provided with a convex extending into the center. The guide pin in the hole can guide the transmission column to slide by using the guide pin to extend into the guide groove. A clamp is connected to the end of the transmission column away from the sleeve, and a combined end combined with the massage head is provided on the clamp; The massage head is linked by the electromagnetic element through the drive element, the transmission element, and the clamp to generate reciprocating telescopic massage vibration.

In the actual application of the above structure, the console 33 can be used for different electrical connections. Setting adjustments, such as setting the impact force and impact frequency of the impact power modules 2, 20, so that the main circuit board 3 can be adjusted to the two impact power modules 2, 20 according to the adjustment of the console 33. The linear rhythmic impact control of force and frequency, and the operating switch 32 can control the main circuit board 31, and activate the impact power modules 2, 20 according to the function commands of the setting program module pressed by the console 33; when the impact of the present invention When the head 4 is not pressed hard against the user’s body, as shown in Figure 6, the shock-absorbing spring 222 and the buffer spring 225 are in an elastically balanced state, and the magnetic core ring 2313 on the bearing rod 231 and the inside of the adapter tube 223 The oscillating coil 2322 is in a dislocation setting state, that is, the magnetic core ring 2313 does not enter the oscillating coil 2332, so that the oscillating coil 2332 does not generate frequency current. At this time, the switch module on the main circuit board 31 (not shown in the figure, and not in this case) Technical features, so technical principles and structures will not be repeated. For example, the chip (CPU, Chip) is maintained in the power-off state, so the main circuit board 31 does not have frequency current passing through, but is in an electrical disconnection state. When it is time to operate the switch 32, the main circuit board 31 does not transmit power to the impact power modules 2, 20, and achieves a no-load protection mechanical structure that does not act when there is no load.

When the impact head 4 strongly touches the user's body, as shown in Figure 5, the shock absorber spring 222 and the cushion spring 225 are pushed by the impact head 4 to form an elastic compression state. At the same time, the magnetic force on the bearing rod 231 The core ring 2313 is moved to the position of the oscillating coil 2322 of the adapter cylinder 223, so that the oscillating coil 2322 generates a frequency current (the technology of converting magnetic energy into electrical energy is not a technical feature of this case, and there are well-known technologies such as Faraday's law, which will not be repeated here). When the switch module on the main circuit board 31 receives the frequency current generated by the oscillating coil 2322, the main circuit board 31 energizes the electromagnetic element 21, and the electromagnetic element 21 generates a magnetic field to drive the driving rod 221 to move forward, and at the same time to drive the rod 221 The sleeve 224 is pushed forward by the impact rod 223, and at the same time the sleeve 224 impacts the bearing rod 231, and the bearing rod 231 transmits the impact force to the impact joint 24 to drive the impact head 4 forward to generate impact massage force. If used continuously When the user’s body is pressed, the operation switch 32 can be continuously pressed to achieve a continuous impact massage action. Once the body is released, the magnetic core ring 2313 on the bearing rod 231 and the oscillating coil 2332 in the adapter tube 233 are misaligned In the setting state, the electromagnetic element 21 is not energized to stop the impact massage action, and the driving rod 221 is pushed back to the original position by the elastic force of the shock-absorbing spring 222 at this time. When returning to the original position, the magnetic core ring 2313 on the bearing rod 231 again moves to the same position of the oscillating coil 2332 of the adaptor barrel 233, repeats the above action, and then achieves the reciprocating movement of the impact power module 2, 20 and the impact head 4 And when the aforementioned impact power modules 2, 20 are in action, the buffer assembly 26 can absorb the impact force when the drive rod 221 is reset to achieve a shock-absorbing structure.

When the pitch adjusting cylinder 232 rotates, the external thread 2321 of the pitch adjusting cylinder 232 rotates on the internal thread 2331 of the connecting cylinder 233, and the pitch adjusting cylinder 232 is displaced back and forth on the connecting cylinder 233. The diagonal groove 2325 rotates counterclockwise to cause a constant spring 2312. Relax, the buffer spring 225 naturally springs forward, thereby increasing the distance between the bearing rod 231 and the sleeve 224. Rotating the diagonal groove 2325 clockwise causes the constant spring 2312 to contract, and its force causes the buffer spring 225 to retract naturally, thus reducing The distance between the bearing rod 231 and the sleeve 224 is further achieved to adjust the impact depth structure of the impact target area. The impact power modules 2 and 20 can adjust the distance between the sleeve portion 2314 and the sleeve 224 at the same time or separately.

During the use of the present invention, the radiator 27 will act with the temperature sensor preset on the main circuit board 31 and start to conduct when the temperature in the casing 1 is too high, driving external air to enter through the air inlet 132 of the back cover 13 In the accommodating space 121 of the case 1, the air passes through the heat dissipation holes 2122 of the heat dissipation cover 212, so that the heat generated by the electromagnetic element 21 is conducted to the outside along with the air flow, and then discharged from the air outlet 114 of the case 1, to achieve In the process, it can also have a good heat dissipation structure.

Hereinafter, an embodiment is used to illustrate the actual application of the above structure. When the present invention is applied to the symptoms of lower lumbar spine rotation to the right (as shown in Figure 8 and the same as shown in Figure 1), the dotted line R'arrow As an example; suppose that the action of the main circuit board 31 is set by the console 33, the linear rhythm impact force of the impact power module 2 is set at the "medium strong" position, and the rhythm impact frequency is set at 12 times per second Position; In addition, the linear rhythm impact force of the impact power module 20 is controlled by the console 33 via the main circuit board 31 to be set at the "weak" position, and the rhythm impact frequency is set to the position of 2 times per second; then, the impact power module The impact head 4 of 2 is placed on the left side facing the fourth section of the lumbar spine, the impact head 40 of the impact power module 20 is placed on the right side facing the fourth section of the lumbar spine, and then the operation switch 32 is pressed down, and then the two groups are activated at the same time Impact power modules 2 and 20 perform impact. After about a few seconds, touch the affected area to feel that the symptoms of right rotation have been eliminated and return to the normal position. These are the two sets of impact power modules 2, 20 that apply differential frequency and Straight-line law power path, and at the same time, looseness and the force of turning to the left as shown by the solid arrow R in Fig. 8, the force of the impact power module 2 is greater than that of the impact power module 20, which can cause it to turn left The impact power module 20 has a smaller force than the impact power module 2, which can produce a buffer protection effect that blocks the impact power module 2), and the use of the impact power module 2 to have a greater frequency than the impact power module 20 can produce a loosening effect (The frequency of impact power module 20 is less than impact power module 2 can produce the effect of balance loosening).

Furthermore; the following symptoms of lumbar rotation to the left (as shown in Figure 9 and the same as Figure 1) are shown in the direction of the dotted line L'arrow as an example, the application setting action is exactly the opposite of the above action; assuming control The station 33 sets the main circuit board 31, and sets the linear rhythm impact force of the impact power module 2 at the "weak" position, and the rhythm impact frequency is set at 2 times per second; in addition, the console 33 passes through the main circuit board 31 , The linear rhythm impact force of the control impact power module 20 is set at the "medium strong" position, and the rhythm impact frequency is set at 12 times per second; then, the impact head 4 of the impact power module 2 is placed facing the lumbar spine On the left side of the fourth section, place the impact head 40 of the impact power module 20 facing the right side of the fourth section of the lumbar spine, and then press the operation switch 32 down, and then start two sets of impact motions at the same time The force modules 2, 20 impact, and after a few seconds, as shown by the solid arrow L in Fig. 9, touch the affected area to feel that the left rotation symptom has been eliminated, and return to the right to the normal position.
