Therefore, the upper limit tooth dropping of the massage machine core can be avoided, the occurrence of collision of the massage swing arm and the machine shell is avoided, the reliability of the massage machine core is ensured, a user can not perceive the collision of the upper limit tooth dropping, the normal massage work can be stabilized, the user experience is further improved, and the motor damage can be reduced. Specifically, as shown in fig. 5, the position states of the strong and weak ejecting gear 41, the sector gear 42 and the code wheel 43 when the upper limit is tooth disengagement are schematically illustrated.
Further, as another executable aspect, the method further comprises:

Therefore, lower limit tooth dislocation of the massage machine core can be avoided, collision of the massage swing arm and the machine shell is avoided, reliability of the massage machine core is guaranteed, a user cannot perceive the collision of the lower limit tooth, normal massage work can be stabilized, user experience is further improved, and meanwhile damage to the motor can be reduced. Specifically, fig. 6 is a schematic view showing the position states of the strong and weak ejecting gear 41, the sector gear 42, and the code wheel 43 when the lower limit is tooth disengagement.
Specifically, in one example, the determining whether the strong and weak ejection motor rushes out the upper stroke limit value according to the current stroke detection value specifically includes:
step B1: and detecting and storing the current movement direction of the strong and weak ejection motor.
Step B2: when the strong and weak ejection motor rotates forwards and the stroke sensor detects that the current stroke detection value is an uplink stroke limit value, the strong and weak ejection motor is determined to eject the uplink stroke limit value.
Similarly, the step of judging whether the strong and weak ejection motor rushes out the lower stroke limit value according to the current stroke detection value specifically includes:

Step C2: and when the strong and weak ejection motor rotates reversely and the stroke sensor detects that the current stroke detection value is a down stroke limit value, determining that the strong and weak ejection motor rushes out the down stroke limit value.
Specifically, as shown in fig. 4, as an example, for explaining the detection of the abnormal region, when the strong and weak ejection motor rotates forward, and the stroke sensor detects that the current stroke detection value is the upper stroke limit value Z1, the stroke sensor detects any stroke detection value at this time, which indicates that the strong and weak ejection motor rushes out the upper stroke limit, and the massage swing arm is subjected to limit tooth stripping; or, if the strong and weak ejection motor rotates reversely, and the stroke sensor detects that the current stroke detection value is the lower stroke limit value Z2, the detected current arbitrary value of the stroke sensor indicates that the strong and weak ejection motor drives out the lower stroke limit, and the lower limit of the massage swing arm is disengaged, the strong and weak ejection motor performs reverse control to avoid collision between the massage swing arm and the machine shell.
In order to ensure the normal movement of the massage method, after reversing the direction of movement of the strong and weak ejection motor, the method comprises:
and when the strong and weak ejection motor moves to a normal stroke range, clearing the ejection record.
Since the strong and weak ejection motor rushes out to an abnormal area, the flushing record is cleared, which is more beneficial to the smooth operation of the massage method. Meanwhile, the occupation of the memory can be reduced, and the operation efficiency is higher.

or when the stroke sensor detects that the current stroke detection value is the lower stroke limit value Z2 and the strong and weak ejection motor rotates forwards, determining that the strong and weak ejection motor does not eject the lower stroke limit value and is in the normal stroke range.
Therefore, the strong and weak ejection motor rotates in a normal stroke range, so that the massage swing arm moves in a normal range, and the strong and weak ejection motor does not need to be controlled reversely. Specifically, fig. 7 is a schematic diagram showing the position states of the strong and weak ejection gear 41, the sector gear 42 and the code wheel 43 in the normal stroke range. The above operation flows can be seen in the overall operation flow chart shown in fig. 3.
Further, as an executable scheme, the method further comprises:
setting an upper stroke punching value Z3 on a code disc of the ejection mechanism in advance, wherein the upper stroke punching value is arranged close to one end of the ejection mechanism and is separated from the upper stroke limit value by a preset distance, namely the preset distance from the upper stroke limit value Z1 to the upper stroke punching value Z3 is an upper abnormal area;
and detecting the motion of the code wheel in real time by using a stroke sensor to obtain a current stroke detection value of the stroke sensor, judging whether the strong and weak ejection motor rushes out an upper stroke rushing-out value Z3 according to the current stroke detection value, and if so, stopping the strong and weak ejection motor when the stroke sensor passes through the uplink abnormal area.
Correspondingly, the method further comprises the following steps:
a down stroke rush-out value Z4 is preset on a code disc of the ejection mechanism, one end of the down stroke rush-out value Z4 close to the ejection mechanism is arranged and is separated from a down stroke limit value Z2 by a preset distance, namely the preset distance from the down stroke limit value Z2 to the down stroke rush-out value Z4 is a down abnormal area;
and detecting the motion of the code wheel in real time by using a stroke sensor to obtain a current stroke detection value of the stroke sensor, judging whether the strong and weak ejection motor rushes out a downlink stroke rushing-out value Z4 according to the current stroke detection value, and if so, stopping the strong and weak ejection motor when the stroke sensor passes through a downlink abnormal area.
It should be noted that, when the stroke rush-out value is detected, it means that the abnormal region is passed through, the region after passing through the abnormal region may be temporarily set as a fault region, at this time, the strong and weak ejection motor is stopped, and the stroke rush-out value is detected only when the stroke rush-out value is in a very special case.
Specifically, as shown in fig. 4, for an example, the fault area detection is described, when the strong and weak ejection motor rotates forward, and the stroke sensor detects that the current stroke detection value is the upper stroke punching value Z3, the stroke sensor detects any stroke detection value at this time, which indicates that the strong and weak ejection motor punches out an abnormal area, and enters the upper fault area; or, if the strong and weak ejection motor rotates reversely, and the stroke sensor detects that the current stroke detection value is the downlink stroke rushing-out value Z4, the detected current arbitrary value of the stroke sensor indicates that the strong and weak ejection motor rushes out an abnormal region, and enters a lower fault region, the strong and weak ejection motor is stopped, so that major faults of the massage machine core are avoided.
