[0003] With the continuous improvement of living standards, people pay more and more attention to physical and mental health, and the demand for various nutritional products and massage instruments is also increasing. Existing massage instruments generally apply massage operations to the human body through rotational motion, linear motion or vibration. Among them, the vibration amplitude of the moving parts in the vibrating massager is not large, and generally only a small eccentric motion is made around its center point or axis; and the moving parts in the rotating massager, in addition to rotating around the axis, will not shift in a straight line. Therefore, wires can be conveniently selected as conductive elements between parts in the vibrating massager and the rotating massager. However, for the linear motion or telescopic massager, because of its large movement amplitude, the wire needs to have enough free length to cooperate with the extension of the massager, but when the massager is retracted, this part of the free length of the wire will be pressed together, not only need to leave enough accommodation space for these wires inside the massager, these wires are easily damaged after repeated pulling and shrinking, and will be entangled on other components due to lack of effective positioning, causing damage to the entire massager, and even endangering the user of the massager in severe cases.

The outer sleeve fixedly connected to the reciprocating nut can drive the massage body to reciprocate relative to the base, thereby applying massage actions such as pressing and kneading to the human body.

An electric scraping member 70 is installed on the inner wall of the outer sleeve. One end of the electric scraping member is movably abutted against the conductive member, and the other end of the electric scraping member is electrically connected to the vibration motor.

[0026] The conductive structure for a reciprocating massage device, wherein a rotary motor 3 is arranged inside a base 1; the reciprocating mechanism includes a reciprocating screw 5 arranged inside an inner sleeve 9 and connected to the rotary motor 3. A reciprocating thread 51 for driving a reciprocating nut 7 to linearly reciprocate is provided on the reciprocating screw. A guiding groove 91 is formed in the wall of the inner sleeve along a direction parallel to the axis. The outer side of the reciprocating nut passes through the guiding groove and is fixedly connected to an outer sleeve 10.

The outer sleeve fixedly connected to the reciprocating nut can drive the massage body to reciprocate relative to the base, so as to apply massage actions such as pressing and rubbing to the human body; during this process, relative movement will occur between the inner and outer sleeves along the axial direction. The electric scraping member on the inner wall of the outer sleeve will continuously abut against the conductive member of the inner sleeve during movement to form an electrical connection, thereby forming a connected circuit among the battery, the conductive member, the electric scraping member, and the vibration motor. The battery can supply power to both the rotary motor and the vibration motor simultaneously to meet the working requirements of the massage device.

[0028] The conductive structure for a reciprocating massage device, sunken positioning grooves 93 are respectively provided on the outer wall of the inner sleeve 9 and the inner wall of the outer sleeve 10.

In addition, the conductive member 60 and / or the electric scraping member 70 can be a cylindrical structure or an elastic metal strip as shown in the figure, and a wavy pressing portion is provided thereon. The pressing portion abuts against the electric scraping member or the conductive member, thereby using its elasticity to ensure that the conductive member and the electric scraping member can stably abut against each other, so as to improve the stability of the electrical connection.

One end of the wire groove communicates with the wire port and the other end communicates to the outside of each conductive member respectively; the wire is embedded from the inner side of the base sleeve through the wire port into the wire groove and connected to the conductive member, thereby connecting the battery and the conductive member; due to circuit setting requirements and different design and usage requirements, two or more conductive members need to be provided in the reciprocating massage device. For the wire connecting the battery and the conductive member, one end is fixedly connected to the battery inside the base sleeve, and the other end is connected to each wire strip after passing through the wire port and the wire groove, which can improve the installation stability of the wire and make the structure between components more compact, and improve the connection strength between components.

One end of the guide pin is provided with a reciprocating strip 61 that moves along the reciprocating thread 51. The reciprocating strip moves along one of the helical grooves (assuming this helical groove is a positive helical groove) until it moves to the end of the positive helical groove and then enters the other helical groove (assuming this helical groove is a reverse helical groove), and then moves along the reverse helical groove to the other end and re-enters the positive helical groove, thereby realizing reciprocating motion; and the other end of the guide pin passes through the reciprocating nut and is connected to the outer sleeve 10, thereby driving the outer sleeve to move. In addition, a guide block 73 that moves along the guide groove 91 is provided on the reciprocating nut 7. The guide pin 6 passes through the guide block and is connected to the outer sleeve 10. This is because the guide block can be set to a larger volume compared to the guide pin, so that its cooperation with the guide groove is more accurate and stable, thereby improving the working stability; at the same time, an installation hole is provided on the outer sleeve 10 at the position opposite to the guide block 73.
