An airflow-driven flexible-patting massage rod structure, comprising:
- a rigid housing, wherein the rigid housing is provided with an inner cavity, an upper portion of the rigid housing is provided with a flow diversion pipe, the rigid housing is provided with at least one recess, wherein the at least one recess is provided with a flow diversion port, and the flow diversion pipe is in communication with the flow diversion port;
- a flexible sleeve, wherein the flexible sleeve covers a peripheral wall of the rigid housing, the flexible sleeve covers the at least one recess and forms an elastic portion, and the elastic portion and the rigid housing enclose a flow diversion cavity;
- a driving device, wherein the driving device is disposed on the rigid housing, the rigid housing is provided with a lithium battery, a Printed Circuit Board (PCB) connected to the lithium battery, and a control device connected to the PCB, the driving device is connected to the PCB, and the control device is configured to control an operating state of the driving device;
- wherein the driving device comprises a rotating device, a driving seat, a guiding seat, a telescopic seat, and a sealing seat;
- wherein the rotating device is provided with a driving shaft, the rotating device is provided with a positioning shell extending upward, the positioning shell is fixed to the rigid housing, the positioning shell extends upward from a wall surface of the rotating device, the positioning shell is located on an outer wall of the rotating device, and the positioning shell and an upper wall of the rotating device enclose a positioning cavity;
- wherein the guiding seat is fixedly mounted between the positioning shell and the rotating device, the guiding seat is provided with the inner cavity, the driving seat is disposed in the inner cavity, and the guiding seat is provided with a first guiding slot extending along a height direction of the guide seat;
- wherein the telescopic seat is provided with a lower chamber, the guiding seat is disposed in the lower chamber, the telescopic seat is provided with a pivotally disposed swing pin in the lower chamber, an end portion of the swing pin passes through the first guiding slot and then engages within an arc-shaped slot, and an upper wall of the telescopic seat is further provided with an upper chamber;
- wherein the sealing seat is fixedly disposed at a rear end of the flow diversion pipe, such that the flow diversion cavity is in communication with a sealing cavity;
- wherein when the rotating device rotates, the arc-shaped slot drives the swing pin to slide along a height direction of the first guiding slot;
- the sliding of the swing pin drives the telescopic seat to move vertically between a position close to the sealing seat and a position away from the sealing seat;
- the vertical movement of the telescopic seat causes a gas pressure between the upper chamber and the sealing cavity to switch between compression and release and adjusts a gas pressure of the flow diversion cavity;
- and
- when the gas pressure of the flow diversion cavity changes, the elastic portion deforms between an expanded position and a retracted position.
