Description

Improved device of impact type massager

Technical Field

The present invention relates to an impact massage device, and more particularly to an improved impact massage device with rear cushion and idle protection.

Background

The common action mode of the small-sized massager mostly adopts the eccentric transmission of a motor to generate high-speed (more than 60 times per second) rotary action so as to achieve the vibration massage effect, or utilizes the high-speed (60 times per second) oscillation mode of an electromagnetic field to generate telescopic action so as to achieve the vibration massage effect, and the action can only generate massage and relieving effects on the surface of the sore part of the body or the superficial layer muscle group; however, in practical application, the deep parts of local muscle groups at meridian points of the body, or parts such as the spine, joints, soft tissues and the like, need to be massaged by low-speed rhythmic impact for 2-12 times per second to achieve the effect of eliminating the ache.

A small-sized (hand-held) massager structure on the market, such as the improved structure of massager No. M446632 in Taiwan patent publication, wherein an upper sleeve is arranged in an outer shell, an electromagnetic component formed by winding a coil around a central conduit is arranged in the upper sleeve, a driving component group is provided with a driving column which extends into the central conduit and is driven by electromagnetism, one end of the driving column is connected with a sleeving component, the other end of the driving column can be sleeved with a spring through an upper connecting rod and then is fixed at the end part of the upper connecting rod through a stopping sheet, a driving component is provided with a lower sleeve connected with the upper sleeve, the lower sleeve is provided with a central hole for accommodating the sleeving component, a driving column is arranged in the central hole to be abutted against the sleeving component through one end, an axially extending guide groove is concavely arranged in the middle section of the driving column, a protruding pin is transversely arranged on the periphery of the lower sleeve, the driving column can be guided to slide by the protruding pin into the guide groove, a clamp is combined with one end of the transmission column far away from the sleeving piece, and a combined end combined with the massage head is arranged on the clamp; the electromagnetic component is used to drive the massage head through the driving component, the transmission component and the clamp, so as to generate reciprocating and telescopic massage vibration.

The above patents and other similar structures cannot be set to simultaneously generate low-speed linear rhythmic impact massage actions with different force channels and frequencies, so that it is still difficult to satisfy the requirements of low-speed rhythmic impact massage on meridian points, deep local muscle groups, or parts such as vertebrae, joints, soft tissues in practical applications.

Further, as the taiwan patent publication No. I494100 of differential frequency type impact massage device, an accommodating space is arranged in the machine shell, one end of the accommodating space is communicated with the outside through two openings, two impact power modules are arranged in the accommodating space, the two impact power modules respectively protrude and extend outside the machine shell through the two openings partially, and respectively combined with a massage head, a control component is formed by connecting a main circuit board, a three-section type operation switch, a control panel and the two impact power modules, a plurality of adjusting units are arranged on the control panel, each adjusting unit is respectively linked with a plurality of adjusting knobs arranged outside the machine shell, and a handle part is extended from the side of the casing, a three-section type operating switch capable of controlling starting is arranged on the handle part, and the adjusting knobs are linked with the adjusting units to form different control adjustments, so that the main circuit board can respectively control the two impact power modules to generate linear dynamic impact effects with different force channels and frequencies.

Although the above patent can generate low-speed linear rhythmic impact massage actions with different force and frequency at the same time, there are still disadvantages to be improved in practical use:

the impact power module has no-load protection in the impact process and no additional buffer mechanism, so that when the impact power module is reset backwards, the impact power module can generate strong vibration by the generated impact force, the whole machine tool is easy to strongly shake, and even mechanical components are abraded and damaged; meanwhile, when the massage head does not contact with a human body, if the switch is pressed carelessly, the impact power module can generate continuous impact, and the massage head is not subjected to reverse thrust force, so that the impact power module can be maintained in the current state all the time, and in the state, an electromagnetic coil in the impact power module can be damaged due to overheating or even cause injury to the body of a user.

In view of the above-mentioned shortcomings, the inventors of the present invention have developed the present invention by studying and improving the shortcomings.

impact power modules

2 and 20 according to the adjustment of the control panel 33, and the operation switch 32 can control the main circuit board 31 to start the

impact power modules

2 and 20 according to the function command of the program module pressed and set by the control panel 33; when the impact head 4 of the present invention is not pressed against the body of the user, as shown in fig. 6, the suspension spring 222 and the buffer spring 225 are elastically balanced, the magnetic core ring 2313 of the support rod 231 and the oscillating coil 2322 of the engaging cylinder 223 are in a dislocated state, that is, the core ring 2313 does not enter the oscillation coil 2332, so that the oscillation coil 2332 does not generate a frequency current, and at this time, the switch module (not shown in the figures, and not a technical feature of the present invention, so that the technical principle and structure are not described in detail), such as the Chip (CPU, Chip) is maintained in the power-off state, therefore, the main circuit board 31 is in an electrically open state without passing a frequency current, and if the switch 32 is operated by mistake, the main circuit board 31 does not transmit power to the

impact power modules

2, 20, and a no-load protection mechanism that does not operate during no-load operation is achieved.

When the impact head 4 is pressed against the body of the user by force, as shown in fig. 5, the shock absorbing spring 222 and the buffer spring 225 are elastically compressed by the inward-contracting thrust of the impact head 4, and at the same time, the magnetic core ring 2313 on the carrier bar 231 moves to the position of the oscillating coil 2322 of the engagement cylinder 223, so that the oscillating coil 2322 generates a frequency current (a technology of converting magnetic energy into electric energy, which is not a technical characteristic of the present case, and has a known technology such as faraday's law, which is not described herein), at this time, the switch module on the main circuit board 31 acts after receiving the frequency current generated by the oscillating coil 2322, the main circuit board 31 energizes the electromagnetic assembly 21, the electromagnetic assembly 21 generates a magnetic field to drive the driving bar 221 to move forward, and at the same time, the driving bar 221 impacts the sleeve 224 via the impact bar 223 to move forward, and at the same time, the sleeve 224 impacts the carrier bar 231, and then the impact force is transmitted to, generating impact massage force. If the user's body is continuously pressed, the switch 32 can be continuously pressed to achieve continuous massage, once the body is released, the magnetic core ring 2313 on the carrying rod 231 and the oscillating coil 2332 in the engaging cylinder 233 are in a staggered arrangement, so that the electromagnetic assembly 21 is not energized to stop the massage, and the driving rod 221 is pushed back to the original position by the elastic force of the shock absorbing spring 222. When the position returns to the original position, the magnetic core ring 2313 on the carrying rod 231 moves to the same position as the oscillating coil 2332 of the engaging cylinder 233 again, and the above actions are repeated, so as to achieve the reciprocating motion of the

impact power modules

2 and 20 and the impact head 4; when the

impact power modules

2 and 20 are operated, the buffer assembly 26 can absorb the impact force generated when the driving rod 221 is reset, thereby achieving a shock-absorbing structure.

When the distance adjusting cylinder 232 rotates, the external thread 2321 of the distance adjusting cylinder 232 rotates on the internal thread 2331 of the engaging cylinder 233, the distance adjusting cylinder 232 generates forward and backward displacement on the engaging cylinder 233, the inclined groove 2325 rotates in the opposite direction to loosen the constant spring 2312, the buffer spring 225 naturally springs forward to enlarge the distance between the bearing rod 231 and the sleeve 224, the inclined groove 2325 rotates in the clockwise direction to contract the constant spring 2312, the force of the inclined groove 2325 enables the buffer spring 225 to naturally retract backward, the distance between the bearing rod 231 and the sleeve 224 is reduced, and therefore the impact depth structure of the impact target area can be adjusted, and the

impact power modules

2 and 20 can adjust the distance between the sleeve 2314 and the sleeve 224 simultaneously or respectively.

In the use process of the present invention, the heat sink 27 receives the over-high temperature starting conduction in the casing 1 along with the preset temperature sensor of the main circuit board 31 to operate, and drives the external air to enter the accommodating space 121 of the casing 1 from the air inlet 132 of the back cover 13, and the air passes through the heat dissipation holes 2122 of the heat dissipation cover 212, so that the heat energy generated when the electromagnetic component 21 operates is conducted outwards along with the air flow, and then is discharged from the air outlet 114 of the casing 1, thereby achieving a good heat dissipation structure in the use process.

The practical application of the above structure will be described below with an embodiment, in which the direction of the arrow of the dotted line R' is taken as an example when the present invention is applied to the symptom of right-rotation of the lower lumbar vertebra (as shown in fig. 8 and also refer to fig. 1); assuming that the control panel 33 sets the motion of the main circuit board 31, the linear rhythm impact force of the impact power module 2 is set at the position of "medium intensity", and the rhythm impact frequency is set at the position of 12 times per second; the control panel 33 controls the linear rhythm impact force of the impact power module 20 to be set at a 'weak' position through the main circuit board 31, and the rhythm impact frequency is set at a position of 2 times per second; then, the impact head 4 of the impact power module 2 is placed at the left side facing the fourth section of the lumbar, the impact head 40 of the impact power module 20 is placed at the right side facing the fourth section of the lumbar, the operation switch 32 is pressed down, then the two groups of impact power modules 2 and 20 are started simultaneously to impact, after about several seconds, the affected part is touched to feel that the right rotation symptom is eliminated and returns to the horizontal normal position, which means that the two groups of impact power modules 2 and 20 respectively apply differential frequency and linear rhythm power paths, and simultaneously generate looseness and a force path returning to the left direction as shown by an arrow R in a solid line in fig. 8, the force path of the impact power module 2 is greater than that of the impact power module 20, so that the impact power module can generate the left direction turning effect (the force path of the impact power module 20 is less than that of the impact power module 2, so that the buffer protection effect of blocking the impact power module 2 can be generated), and the frequency of the impact power module 2 is greater than that of the impact power module 20, so that the The frequency of the force module 20 is less than that of the impact power module 2 to generate the effect of balance loosening).

Thirdly, performing the operation; for the lower lumbar left rotation symptom (as shown in fig. 9 and also fig. 1), the direction of the arrow of the dashed line L' is taken as an example, and the setting operation is applied to generate the reverse function just like the above-mentioned operation; assuming that the control panel 33 sets the main circuit board 31, the linear rhythm impact force of the impact power module 2 is set at a 'weak' position, and the rhythm impact frequency is set at a position of 2 times per second; in addition, the control panel 33 controls the linear rhythm impact force of the impact power module 20 to be set at the position of 'medium intensity' through the main circuit board 31, and the rhythm impact frequency is set at the position of 12 times per second; then, the impact head 4 of the impact power module 2 is placed at the left side facing the fourth lumbar vertebra, the impact head 40 of the impact power module 20 is placed at the right side facing the fourth lumbar vertebra, the operation switch 32 is pressed down, then the two groups of impact power modules 2 and 20 are started simultaneously to impact, and after about several seconds, as shown by a solid arrow L in fig. 9, the affected part is touched to feel that the left rotation symptom is eliminated, and the affected part returns to the right at the horizontal normal position.
