A swing fulcrum of the swing rod <NUM> can be two opposite edges (such as a first edge and an opposite second edge) of the swing rod <NUM> or a middle position of the swing rod <NUM>. The rotary motor <NUM> is powered by the battery <NUM> and controlled to be started or stopped by the circuit board <NUM>.

Referring to <FIG>, a massage protrusion <NUM> is arranged at one end of the swing rod <NUM> away from the reversing member <NUM>, and protrudes outwardly from a surface 1a of the housing <NUM> to swing back and forth with the swing rod <NUM>. The rotary motor <NUM> starts to rotate, due to provide the reversing member <NUM>, the rotation motion of the rotary motor <NUM> is output to the swing rod <NUM> and then converted into a linear reciprocating movement by the swing rod <NUM>, such as up and down reciprocating, or left and right reciprocating, or back and forth reciprocating, etc, thus, the swing rod <NUM> swings back and forth around the swing fulcrum thereof, to further drive the massage protrusion <NUM> that has been arranged on the swing rod <NUM> to swing back and forth, so as to swing and touch the human body. Compared with the reciprocating beating massage of the rotation mechanism in the related art, the swing member <NUM> of the present disclosure can't be jammed, and can be stably and reliably operated. At the same time, the reciprocating swing of the massage protrusion <NUM> has a better massage effect than the vibration massage of a single motor, so that user's experiences are improved.

In an embodiment of the present disclosure, the hard shell <NUM> includes a first hard shell <NUM> and a second hard shell <NUM>, one end that the first hard shell <NUM> is connected with the second hard shell <NUM> is provided with an opening <NUM>, the swing rod <NUM> extends outside from the opening <NUM>, and the massage protrusion <NUM> is arranged on an extending part of the swing rod <NUM> that has been extended out of the opening <NUM>. The opening <NUM> is arranged so that the swing rod <NUM> that is received in the opening <NUM> extends therefrom to connect with the massage protrusion <NUM> for driving further the massage protrusion <NUM> to swing.

In an embodiment of the present disclosure, the massage protrusion <NUM> and the soft shell <NUM> are integrated with each other for sealing the extending part of the swing rod <NUM> that has been extended from the opening <NUM> of the hard shell <NUM>.

Furthermore, the massage protrusion <NUM> of the first embodiment is a tongue-shaped configuration, it can be understood that the massage protrusion <NUM> can also be a finger-shaped configuration, which can simulate a tongue or fingers of the human body to swing and touch massage the human body.

As an implementation, referring to <FIG> and <FIG>, the reversing member <NUM> is an eccentric shaft <NUM>, and the swing rod <NUM> is a nozzle member <NUM>. The nozzle member <NUM> includes a rotation fulcrum <NUM> rotationally connected with the housing <NUM> and a mouth structure <NUM> located on a first edge 51a of the rotation fulcrum <NUM>, the massage protrusion <NUM> arranged on an opposite second edge 51b of the rotation fulcrum <NUM>. A first portion 40a of the eccentric shaft <NUM> is connected with the rotary motor <NUM>, an opposite second portion 40b of the eccentric shaft <NUM> extends into the mouth structure <NUM>, the eccentric shaft <NUM> rotates to drive the mouth structure <NUM> to move linearly back and forth, so that the whole nozzle member <NUM> swings around the rotation fulcrum <NUM>.

That is, in the first embodiment of the present disclosure, the eccentric shaft <NUM> and the nozzle rod <NUM> are matched with each other to cooperatively convert the rotary motion of the rotary motor <NUM> into the reciprocating swing, and the eccentric shaft <NUM> rotates with the rotary motor <NUM>, and an eccentric part of the eccentric shaft <NUM>, that is, the part of the eccentric shaft <NUM> extending into the mouth structure <NUM>, also rotates with the rotary motor <NUM>. In the rotation process, the eccentric part of the eccentric shaft <NUM> touches upper and lower inner walls or left and right inner walls of the mouth structure <NUM> back and forth, so that the nozzle member <NUM> swings back and forth around the rotation fulcrum <NUM>.

Specifically, referring to <FIG>, the mouth structure <NUM> includes a first rod <NUM> and an opposite second rod <NUM> arranged on the nozzle member <NUM>, and a movable cavity <NUM> formed between the first rod <NUM> and the second rod <NUM>, the eccentric shaft <NUM> extending into the movable cavity <NUM> and in contact with the first rod <NUM> and the second rod <NUM> back and forth during the rotation process thereof, so that the mouth structure <NUM> moves linearly back and forth. The part of the eccentric shaft <NUM> extending into the movable cavity <NUM> is movable rather than being fixed in the movable cavity <NUM>. During rotation, the part contacts the first rod <NUM> and the second rod <NUM> back and forth, so as to drive the mouth structure <NUM> to move linearly up and down or left and right, and then due to set the rotation fulcrum <NUM>, the linear movement of the mouth structure <NUM> drives the whole nozzle member <NUM> to swing.

Furthermore, referring to <FIG>, the eccentric shaft <NUM> includes a first shaft <NUM> and a second shaft <NUM> eccentrically arranged on the first shaft <NUM>, the first shaft <NUM> connected with the rotary motor <NUM>, and the second shaft <NUM> extending into the movable cavity <NUM> of the mouth structure <NUM>. The first shaft <NUM> and the rotary motor <NUM> can be connected through a pin shaft or a key, the rotary motor <NUM> rotates to drive the first shaft <NUM> to follow rotating, and then to further drive the eccentric second shaft <NUM> to rotate. Because the part of the second shaft <NUM> extending into the movable cavity <NUM> of the mouth structure <NUM> is movable, when the second shaft <NUM> rotates, the part of the second shaft <NUM> extending into the movable cavity <NUM> can repeatedly contact the first rod <NUM> and the second rod <NUM> of the mouth structure <NUM>, for example, when the second shaft <NUM> rotates in an upper half circle, the part of the second shaft <NUM> extending into the movable cavity <NUM> contacts the first rod <NUM> and then pushes the first rod <NUM> from a middle position to the highest position, so that the whole nozzle member <NUM> completely up-swings; when the second shaft <NUM> rotates in a lower half circle, the part of the second shaft <NUM> extending into the movable cavity <NUM> contacts the second rod <NUM> and then pushes the second rod <NUM> from the middle position to the lowest position, so that the whole nozzle member <NUM> completely low-swings. In this way, the reciprocating swing of the whole nozzle member <NUM> is completed, so that the massage protrusion <NUM> arranged on the nozzle member <NUM> is driven to follow the reciprocating swing.
