In the present embodiment, gear assembly includes first rotating shaft 410, and eccentric wheel 300 is socketed in outside first rotating shaft 410, and first
Shaft 410, which protrudes into limiting slot 22 and limits with limiting slot 22, to be cooperated.
In the present embodiment, 30 length L of block piece and 22 length ratio of limiting slot are 1:2.3-4.That is, 22 length of limiting slot
It is identical as the total stroke length of block piece 30.
In the present embodiment, massager further includes third shaft 430 and the axle sleeve being fixedly connected with third shaft 430 440, and
Three shafts 430 and axle sleeve 440 are to be arranged vertically, and the rotation of axle sleeve 440 is socketed in lower case 520, and third shaft 430 passes through fluting 23
20 top of driving member is stretched out, massage head 200 is socketed in 430 upper end of third shaft, and driving member 20 passes through when moving left and right
Axle sleeve 440 drives third shaft 430 to move along fluting 23, finally massage head 200 is driven to move left and right.It needs to illustrate
It is that the term of the application indicating position or positional relationship is to be based on the orientation or positional relationship shown in the drawings, is merely for convenience of
Description, rather than the equipment of indication or suggestion meaning or element must have a particular orientation, constructed and grasped with specific orientation
Make, therefore should not be understood as the limitation to the application.
In the present embodiment, massager further includes rotating-massage-head 600, and gear assembly further includes the second shaft 420, and rotation is pressed
It rubs and first 600 is mounted in the second shaft 420 and is rotated with the rotation of the second shaft 420.The specific structure of gear assembly is existing
There is technology, repeats no more.
In the present embodiment, optical beam generating device 10 is located at 30 top of block piece, the light beam 11 that optical beam generating device 10 generates
The medium position of 11 face block piece 30 of light beam when being blocked.
Controller is connected with optical beam generating device 10, motor 100, controller detection block piece 30 do not block light beam 11 when
Between with judge block piece 30 be located at the left or right side towards light beam 11 so that control massage head 200 reset or positioning.
In the present embodiment, as shown in fig. 6, block piece 30 is located at the right side of light beam 11 when massage head 200 resets；Such as figure
Shown in 7, block piece is located at the left side of light beam 11 when massage head 200 positions.
Block piece 30 turn left end motion when since block piece 30 block 11 state of light beam to counting not blocking 11 state of light beam
When, arrive that block piece 30 back moves the duration T1 for blocking light beam 11 again and block piece 30 is turned right and hidden when moving from block piece 30 again
Gear beam state starts timing, arrives block piece 30 again and back move and block the duration T2 of light beam again and deposit to not blocking beam state
In difference, that is, T1 is less than T2, and reduced value T3 of the access value between T1 and T2, controller is by detecting from block piece 30
It blocks beam state and starts timing, arrives block piece 30 again and back move and block the duration T of light beam again to not blocking beam state
And compare T and T3, if T is greater than T3, judge that block piece 30 is located at 11 right end of light beam, if T is less than T3, judgement is blocked
Part 30 is located at light beam left end.
When light beam 11 is blocked, the optocoupler signal that photoelectrical coupler generates is high level；When light beam 11 is not blocked, photoelectricity
Coupler generate optocoupler signal be low level, as a result, its working principle is that:
When massager resets, massage head 200 is in right end position as shown in FIG. 6；
It is needed to be reset when massager just powers on, when controller detects that optocoupler signal is low level, indicates block piece
30 leave light beam 11, start timing at this time, and when block piece, which back moves, blocks light beam 11 again, optocoupler signal becomes high electricity
It is flat, terminate timing at this time, detection time T, controller compares detection time T and reduced value T3, and T3 value is 700
Millisecond；
1) when indicating rigid start recording detection time T when T is greater than or equal to 700 milliseconds, block piece 30 is located at light
The right end of beam 11, detection time T are T2, then when needing in next operational process not to be blocked for second of light beam 11,
Controller control motor 100 stops operating immediately, realizes reset function, and the position that massage head 200 stops at this time is multiple
Position position, as shown in Figure 6；
2) when indicating rigid start recording detection time T when T is less than 700 milliseconds, block piece 30 is located at light beam 11
Left end, detection time T are T1, then, the light beam 11 in next operational process are needed to control when not being blocked next time
Device control motor 100 stops operating immediately, and the position that massage head 200 stops at this time is reset position.
The optical grating construction is also able to cooperate massage head and realizes massage manipulation function, as massage head 200 is simulated
Need to be located adjacent to 600 side of rotating-massage-head before massage movement, as shown in Figure 7.
During massager massage, massage program are as follows:
The first step, 100 revolving speed of motor changes from low to high at 1-10 seconds, and massage head revolving speed is gradually accelerated at this time；
Second step, 100 revolving speed of motor changes from high to low at 11-20 seconds, and 200 revolving speed of massage head gradually subtracts at this time
Slowly；
Third step, motor reversal changes from low to high, then from high to low at 21-40 seconds；
At 41 seconds, massage head 200 is positioned for 4th step, and then motor 100 is turned 0.5 second with high speed, is paused 0.3 second,
It is repeated 3 times, can be realized and simulate intermittent massage manipulation；
5th step, motor 100 inverts again after intermittent massage, equally positions massage head 200, again mould
Intend intermittent massage manipulation；
6th step repeats above the first to five step.
The above are a massage periods, are required to position on massage head 200 in the 4th step and five steps.
Its working principle is similar to above-mentioned reset principle, are as follows:
When controller detects that optocoupler signal is low level, indicates that block piece 30 leaves light beam 11, starts timing at this time,
When block piece, which back moves, blocks light beam 11 again, optocoupler signal becomes high level, terminates timing at this time, detection time T,
Controller compares detection time T and reduced value T3, and T3 value is 700 milliseconds；
1) when indicating rigid start recording detection time T when T is greater than or equal to 700 milliseconds, block piece 30 is located at light
The right end of beam 11, detection time T are T2, then the light beam 11 in next operational process is needed not to be blocked next time
When, controller control motor 100 stops operating immediately, realizes positioning function, and the position that massage head 200 stops at this time is
Position location, as shown in Figure 7；
2) when indicating rigid start recording detection time T when T is less than 700 milliseconds, block piece 30 is located at light beam 11
Left end, detection time T are that T1 then needs the light beam 11 in next operational process not next being blocked for the second time
When, controller control motor 100 stops operating immediately, and the position that massage head 200 stops at this time is position location.
Since this kind of optical grating construction is not only able to achieve reset function, but also it is able to achieve positioning function, cost can be greatly saved, reduced
Massager size, market prospects are extensive.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model
For.
