Personal care device with high pressure indicator

A personal care device configured to generate a feedback signal in response to excessive pressure applied by a user, the device comprising:

• a body portion comprising a first interacting portion and a drivetrain;
• and
• a transmission shaft comprising a second interacting portion;
• wherein at least a portion of the body portion is flexible relative to the transmission shaft to allow the first interacting portion to move, in response to a force applied by the user, from a first position in which the first interacting portion does not physically interact with the second interacting portion, to a second position in which the first interacting portion physically interacts with the second interacting portion;
• and
• wherein the physical interaction between the first interacting portion and the second interacting portion generates a feedback signal to the user,
• wherein the drivetrain is configured to oscillate the transmission shaft, and wherein the feedback signal is responsive to a change in the oscillation of the transmission shaft as a result of the physical interaction between the first interacting portion and the second interacting portion, said change in oscillation indicating that excessive pressure is being applied by the user.

A personal care device configured to generate a feedback signal in response to excessive pressure applied by a user, the device comprising:

• a body portion comprising a first interacting portion, and further comprising a drivetrain;
• and
• a transmission shaft comprising a second interacting portion, wherein the drivetrain is configured to oscillate the transmission shaft at a first frequency during use of the personal care device;
• wherein at least a portion of the drivetrain is flexible to allow the first interacting portion to move, in response to a force applied by the user, from a first position in which the first interacting portion does not physically impact the second interacting portion, to a second position in which the first interacting portion physically interacts with the second interacting portion at each oscillation of the transmission shaft;
• and
• wherein each physical interaction between the first interacting portion and the second interacting portion generates a feedback signal to the user applied,
• wherein the drivetrain is configured to oscillate the transmission shaft, and wherein the feedback signal is responsive to a change in the oscillation of the transmission shaft as a result of the physical interaction between the first interacting portion and the second interacting portion, said change in oscillation indicating that excessive pressure is being applied by the user.
