Abstract
A massage apparatus for massaging on a user's body by a massage head moving at least linearly in a longitudinal direction of the massage head, configured so that a massaging element moves toward the massage head by way of air pressure fluctuation in an air chamber when a driving element is moved from a first position to a second position. In addition, the stroke center position of the reciprocating movement of the driving element moved between the first position and the second position is configured to be changeable.
Claims12
A massage apparatus which at least linearly drives a massage head at least linearly in a longitudinal direction of the massage head and performs a massaging operation on a user's body, comprising:
- a main housing,
- a cylinder which is arranged in the main housing and extended in the longitudinal direction of the massage head,
- a massaging element which drives linearly in the longitudinal direction of the massage head in the cylinder and interchangeably connects the massage head,
- a driving element which is slidably arranged in the cylinder and is configured to move the massaging element,
- an air chamber located inside the cylinder between the driving element and the massaging element, and
- a driving apparatus which drives the driving element,
- wherein the driving element is arranged inside the cylinder such that it reciprocally moves in the cylinder along the longitudinal axis of the cylinder between a first position at which the driving element is most remote from the massage head and a second position at which the driving element is closest to the massage head,
- when the driving element is moved from the first position to the second position, the driving element moves the massaging element toward the massage head and the massaging element interchangeably connects the massage head, and
- wherein the reciprocal movement of the driving element has a stroke center position relative to the cylinder between the first position and the second position;
- and
- wherein the driving element and driving apparatus are configured to change the stroke center position.
A massage apparatus in which a massage head drives at least linearly in a longitudinal direction of the massage head and performs a massaging operation on a user's body, comprising:
- a main housing,
- a cylinder which (1) is arranged inside the main housing and (2) has a center axis,
- a massaging element which is slidably arranged within the cylinder,
- a driving element which is slid inside the cylinder and drives the massaging element,
- a connection rod which is connected to the driving element,
- a crank mechanism which is connected to the connection rod and drives a driving element as the driving element,
- wherein:
- the driving element has a bottom dead center position in which the driving element is most remote from the massage head and a top dead center position in which the driving element is closest to the massage head,
- the connection rod has a longitudinal axis, and
- the cylinder, the driving element and the connection rod are configured such that, at some point when the driving element is between the top dead center position and the bottom dead center position, but not at the top dead center position or the bottom dead center position.
