Description

Technical Field

[0001] The present disclosure relates to a sexual stimulation device, and more specifically, to a reciprocating sexual stimulation device.

Background Art

[0002] Sexual stimulation devices, also known as sex toys or adult toys, are designed to produce various different movements such as vibration, rotation, and thrusting. The thrusting movement is generated by a reciprocating action in which an element moves back and forth on a straight line. Since such devices generally use an electric motor capable of generating a rotational movement, the reciprocating action is generated by a mechanical element such as a cam that converts the rotational movement of the motor into a reciprocating movement, or by a push rod attached to a rotating disk or wheel, and the rotating disk or wheel is driven to push and pull the rod along the reciprocating direction.

[0003] However, such existing approaches for providing a reciprocating action may not be suitable for application to sexual stimulation devices due to low power efficiency, being forced into an ungainly device shape to accommodate the necessary mechanical elements, limited stroke length, insufficient driving force in a portable configuration, and asymmetric rising and falling stroke forces.

Best Mode for Carrying Out the Invention

[0009] Certain terms are used for clarity in describing exemplary embodiments of the present disclosure shown in the drawings. However, it should be understood that the present disclosure is not intended to be limited to any specific term selected, and that each specific element includes all technical equivalents that operate in a similar manner.

[0010] An exemplary embodiment of the present invention provides a sexual stimulation device. This sexual stimulation device utilizes various screw-nut configurations to generate reciprocating motion from the unidirectional rotational motion of an electric motor, thereby providing a desired stimulation vector in a compact and portable form factor and enabling efficient use of battery power.

[0011] For example, a sexual stimulation device includes a base assembly, a top assembly, and an expandable tube connecting the base and top assemblies. A threaded screw is fixed to a rotary motor in the base assembly, thereby connecting the threaded screw to the base assembly and driving it to rotate by the motor. The threaded screw extends into the top assembly, but it is not connected to the top assembly. The top assembly includes a threaded nut or guide pin fixedly connected to the top assembly, and the threaded nut or guide pin engages with the threaded screw. Thus, as the motor rotates the screw, the top assembly is driven up and down by the nut / guide pin, and the expandable tube has the function of maintaining the top assembly connected to the base assembly. In this way, reciprocating motion is established.

[0012] The exterior of the top assembly includes a stimulating shape, thereby allowing the user of the device to receive stimulation from the reciprocating motion of the top assembly relative to the base assembly. The base assembly includes mounting means for detachably attaching it to a stationary object.

[0013] The direction of the reciprocating motion is alternately switched between expansion and contraction by one of several different means. For example, the direction of the reciprocating motion is alternately switched by reversing the rotation of the motor. Alternatively, a threaded screw is threaded with a double helix groove (including an upward groove and a downward groove, the upward groove being for driving the top assembly away from the base assembly, and the downward groove being for driving the top assembly toward the base assembly), so that the guide pin is lifted (away from the base assembly) by the rotation of the screw set in the upward groove, and when the guide pin reaches the top of the screw the upward groove transitions to the downward groove, pushing the guide pin downward (towards the base assembly) by the rotation of the screw. When the guide pin reaches the bottom of the screw the downward groove transitions to the upward groove, pushing the guide pin upward again. Since the guide pin is fixedly coupled to the top assembly, the top assembly exhibits reciprocating motion when the guide pin is driven to move toward or away from the base assembly. Various other components may be included to facilitate the reciprocating motion or to add a stimulating function to the device. Many of these components and their operation will be described in detail below. However, it should be understood that any combination of these various other components can be used in relation to the basic operating mechanisms described above.

[0014] In various drawings, many of the same elements are shown in multiple drawings, but they are not described again in every drawing in which they appear. Therefore, if an element is not described in one drawing, it should be assumed to be similar to the corresponding element shown and described in at least another drawing. The same reference number may represent the same element throughout the specification and drawings.

[0015] Figure 1 is a cross-sectional view of a reciprocating stimulation device 100 according to an exemplary embodiment of the present invention. The top assembly described above includes a stimulation body 102, and the base assembly described above includes a handle portion 108. The top assembly further includes a stimulation component 101 capable of providing vibrational force, which is done by including a vibration motor that can be powered from the base component via a conductive subassembly 104, the conductive subassembly 104 may include wires.

[0016] The base assembly, for example, includes a rotary motor 107 and a controller 109 within the handle portion 108, the rotary motor 107 being driven by a battery or other power source 110, and the controller 109 regulating the operation of the rotary motor 107, the operation of the stimulation component 101, and the charging of the battery 110, and may also provide various other functions. The controller 109 may include logic circuits and may also include a microprocessor, system-on-a-chip, etc.

[0017] The controller can be programmed to allow the user to operate the device 100 using one or more buttons located on it, and to control various operating modes, such as the activation of the stimulation component 101 and the initiation of reciprocating motion. The controller can also utilize various elements of network hardware to enable control of the device 100's operation via a short-range wireless connection (e.g., Bluetooth) or the internet.

[0018] The expandable tube 106 connects the outside of the stimulator body 102 to the outside of the handle portion 108. The expandable tube 106 allows the stimulator body 102 to move closer to or further away from the handle portion 108, while also preventing the inside of the device 100 from being exposed and preventing the user from being pinched by the device 100.

[0019] The rotary motor 107 rotates under the control of the controller 109 and drives the linear reciprocating mechanism 105. The linear reciprocating mechanism 105 may utilize one or more screws, such as a screw pair, a nut and / or guide pin, an electromagnetic reciprocating mechanism, a crank reciprocating mechanism, a reciprocating swashplate mechanism, etc., to move the stimulator body 102 closer to or further away from the handle portion 108, as described above. Inside the stimulator body 102 is a load member 103 driven by the linear reciprocating mechanism 105. Since the load member 103 is fixedly coupled to the stimulator body 102, the reciprocating motion of the load member 103 is transmitted to the stimulator body 102.

[0020] Figure 2 is a perspective view of a reciprocating stimulation device 100 according to an exemplary embodiment of the present invention. As shown in this figure, the stimulation body 102 may include various external elements such as recessed channels and raised ribs to provide stimulation to the user. The expandable tube 106 may include a ribbed elastic membrane for expansion and contraction. For example, the expandable tube 106 may include silicone or a flexible bellows. The expandable tube 106 may be formed of a single continuous membrane that encloses both the stimulation body 102 and the handle portion 108, providing a continuous, impermeable outer shell around the device 100. The stimulation body 102, the expandable tube 106, and the handle portion 108 may each be substantially cylindrical, and these three elements are arranged concentrically. These three elements may all have a common diameter, or their diameters may be 6 mm or less from each other. Alternatively, each of these three elements may have its own diameter, and these diameters may differ from each other by 6 mm or more.

[0021] The exterior of the handle portion 108 may include various control elements, such as a first button 111A for controlling the vibration of the stimulation component 101 and a second button 111B for controlling the reciprocating motion. The first button 111A may be used, for example, to switch vibration modes, and the second button 111B may be used, for example, to start / stop the reciprocating motion. The second button 111B may also be used to fully extend or contract the load member 103.

[0022] The control unit 112, as shown in the figure, is also located outside the handle unit 108 and may provide additional inputs / outputs. The control unit 112 may include, for example, a touchscreen, buttons, knobs, controls, etc.

[0023] The detachable base 113 is configured to fit onto the handle portion 108, so that the device 100 can be attached to a fixed structure during use. The detachable base 113 has a threaded post for screwing into a threaded cavity of the handle portion 108, and the opposite end of the detachable base 113 may be a suction cup or some other mounting means.

[0024] Figure 3 is an exploded view of a reciprocating stimulation device 100 according to an exemplary embodiment of the present invention. The figure shows that the base assembly includes a removable shell 117 that engages with a stationary shell 119, for example, by a screw. The removable shell 117 can be removed to expose a battery 110, a rotary motor 107, and various other components. The device 100 may further include a charging port 120, the first and second buttons 111A / B described above, and a printed circuit board (PCB) 118.

[0025] The trunking 114 may be included behind the removable shell 117 as a protected passage for wiring and / or other conductive elements to extend from the rotary motor 107 to the PCB 118. These wiring and / or other conductive elements may pass through an opening 115 located behind the removable shell 117.

[0026] The stimulation body 102 (not shown) houses the load member 103 and the stimulation component 101.

[0027] Figure 4 is a cross-sectional view of a reciprocating stimulation device 100 according to an exemplary embodiment of the present invention. While Figure 1 shows the use of a linear reciprocating mechanism 105, which can be a general mechanism for providing reciprocating motion, the configuration in Figure 4 shows a specific approach to achieving reciprocating motion. Here, the handle portion 108 is again shown as including a battery / power supply 110, a controller 109, and a rotary motor 107. The stimulation body 102 is again shown as being connected to the handle portion 108 by an expandable tube 106. However, the load member 103 is shown as including a nut 122 fixedly coupled to the load member 103 by, for example, a longitudinal force bearing structure (e.g., a crossbar). The nut is threaded to fit into a helical groove of a screw 124, and as the screw is rotated by the rotary motor 107, the nut 122 is pushed to carry the load member 103 together, toward and away from the handle portion 108. The guide member 123 has the function of stabilizing the nut 122, and by extension the stimulator body 102, on the handle portion 108, thereby minimizing lateral shaking and instability. This can be achieved by a first post fixed to the nut 122, a second post fixed inside the handle portion 108, and a sliding configuration for slidably positioning the first and second posts relative to each other. A conductive subassembly 104 may extend from the controller 109 and / or battery 110 to the stimulator component 101, and the stimulator component 101 may include a vibration motor to supply power to and drive the stimulator component 101. With this configuration, the direction of reciprocating motion can be controlled by the controller 109 controlling the rotation direction of the rotary motor 107. By periodically and alternately switching the rotation direction of the rotary motor 107, the desired reciprocating motion can be achieved.

[0028] As described above, according to another approach, the desired reciprocating motion is achieved without the need to periodically reverse the direction of rotation of the rotary motor 107. According to this approach, a screw 124 having a double helix groove is employed. Figure 5 is an exploded view of a reciprocating stimulation device 100 utilizing a double helix groove screw 124 according to an exemplary embodiment of the present invention. Here, an internal sleeve 136 is placed on the rotary motor 107. The internal sleeve 136 includes a linear guide hole 134. The screw 124 is also placed inside the internal sleeve 136. The screw 124 is fitted onto the rotary motor 107 so that the rotary motor 107 rotates the screw 124. The screw 124 has a double helix groove 131 on its surface, including an ascending helix groove and a descending helix groove (e.g., a left-turning helix groove and a right-turning helix groove). The two helix grooves intersect each other, and their ends are connected at both the top and bottom of the screw 124.

[0029] The nut is formed when the lower cover 133 and the upper cover 129 are joined together by a guide pin 132. The guide pin 132 protrudes from a straight guide hole 134 in the internal sleeve 136. Thus, as the rotary motor 107 rotates, the nut formed by the lower cover 133 and the upper cover 129 moves up and down, depending on which helical groove the guide pin 132 is currently positioned in, as the rotation of the nut is prevented by the arrangement of bumps in the straight guide hole 134. As described above, the direction of movement of the nut changes when the guide pin 132 reaches either the top or bottom of the screw 124, and then moves to the other groove.

[0030] It should be understood that the nut configuration may include one or more guide pins 132. For example, the nut configuration may include a pair of bumps located on the opposite side of the nut, each of which is housed in a different linear guide hole 134 of the internal sleeve 136, so that there may be two linear guide holes 134 on the opposite side of the internal sleeve 136. This may provide additional stability than embodiments in which only one bump is used.

[0031] The outer sleeve 126 is coupled to a nut formed by the lower cover 133 and the upper cover 129 by the arrangement of one or more mounts 128A and 128B. Thus, as the nut moves up and down, it carries the outer sleeve 126 up and down with it. The support 127 is coupled to the outer sleeve 126, and the case 125 is coupled to the support 127, so that the case 125 of the device 100 can achieve the desired reciprocating motion.

[0032] Power can be supplied from the base to the top of the device, for example, by a pair of conductive strips 135A and 135B arranged around the internal sleeve 136, thereby powering a vibration motor or other stimulation component located inside it. Each of the conductive strips 135A and 135B is electrically connected at its bottom to wiring that connects to the power supply and at its top to wiring that connects to the vibration motor or other stimulation component. By using conductive strips in this way, friction between the internal sleeve 136, which remains stationary relative to the base, and the external sleeve 126, which moves up and down relative to the base, can be reduced because using wiring between these two sleeves would likely interfere with the reciprocating motion.

[0033] Figure 6 is a cross-sectional view of the reciprocating stimulation device 100 shown in Figure 5. Here, the device 100 is shown in a fully retracted state, with the outer sleeve 126 positioned around the inner sleeve 136. Here, the handle portion 108 surrounds the shell 117, the power supply / battery 110, the rotary motor 107, and the PCB 118 on which the controller is located. The charging port 120 and buttons 111A / 111B may protrude from the shell 117 and the handle portion 108.

[0034] The handle portion 108 is externally reconnected to the stimulator body 102 by an expandable tube 106. Inside the internal sleeve 136, a screw 124 with a double helix groove is coupled to the rotary motor 107. The lower cover 133, together with the upper cover 129, forms a nut that engages with the groove 131 of the screw 124 (for example, with the guide pin 132). A pair of mounts 128A and 128B secure the nut assembly, including the lower cover 133, the upper cover 129, and the guide pin 132, to the external sleeve 126. The external sleeve 126 is coupled to the stimulator body 102, and above the external sleeve 126 and inside the stimulator body 102 is a support 127. A chamber 139 extends through the support 127, and wiring can pass through the chamber 139 and through a first hole 138 in the case 125 to power the vibration motor 137 located inside the top of the stimulator body 102.

[0035] Figure 7 is a series of perspective views of the screw 124 with the nut assembly positioned, as shown in Figures 5 and 6. The nut assembly, including the lower cover 133, upper cover 129, guide pin 132, and a pair of mounts 128A and 128B, is shown together in a transparent contour form to allow for a clearer visualization of the engagement of the nut assembly around the rotating screw 124. As the screw 124 rotates in one direction, the nut assembly moves up and down along the screw 124 to complete one full cycle, and then continues to provide the reciprocating motion described above.

[0036] Figure 8 is a cross-sectional view of a reciprocating stimulation device 100A according to an exemplary embodiment of the present invention. Any one or more elements of the device not described in detail with respect to this figure should be assumed to be analogous to the corresponding elements described elsewhere in this disclosure.

[0037] Here, the screw 124 may have a double helical groove configuration as described above. In this configuration as well, the battery / power supply 110, the rotary motor 107, and the controller 109 are located within the handle portion 108, but here the nut 122 is stationary within the handle portion because it is fixed inside the handle portion 108 using a retaining ring. A torque receiving structure may be used to couple the rotary motor 107 to the screw 124 in order to rotate the screw 124 by the rotation of the motor 107. However, here the nut 122 is stationary relative to the handle portion 108, so the screw 124 is pulled up and down within the stationary nut 122 as it rotates. Therefore, the torque receiving structure is configured to transmit rotational force to the screw 124 while the screw 124 moves freely up and down.

[0038] The conductive subassembly 104 carries power from the battery / power supply 110 to the conductive subassembly 143, from which power is carried to the stimulating component 101. The retractable tube 106 again connects the outside of the handle portion 108 to the outside of the stimulating body 102. The screw 124 is fitted into a ball bearing 142, and the ball bearing 142 is fitted into a load member 103, so that the screw 124 can push and pull the load member 103 up and down without the load member 103 having to rotate with the rotation of the screw 124. In this way, the reciprocating motion of the screw 124 can be transmitted to the load member 103 without the rotational motion of the screw 124 affecting the load member 103. Again, the load member 103 is fitted into the stimulating body 102, so that the stimulating body 102 exhibits reciprocating motion.

[0039] Figure 9 is an exploded view of the components of the reciprocating stimulation device 100A shown in Figure 8. Here, the rotary motor 107 is connected to the torque receiving structure 150. (For example, a shaft or prism)The cylinder rotates, thereby transmitting rotational force to the screw 124. The cylinder 149, which has a hollow interior, is held in place by a ring-shaped base 151, and these elements together are fixed to the handle. A pair of conductive scrapers 147A and 147B are fitted into the cylinder 147 and can carry power from the battery. Each of the conductive scrapers 147A and 147B includes an arched contact 146 at its upper end. The arched contact 146 establishes an electrical connection with the corresponding conductive strips 135A and 135B, which are part of the reciprocating structure, so that the arched contact 146 of the conductive scrapers 147A and 147B slides along the conductive strips 135A and 135B as the conductive strips 135A and 135B exhibit reciprocating motion, thereby maintaining the electrical connection, carrying power to the device 100A, and supplying power to the stimulating component 101. The conductive scrapers 147A and 147B and the conductive strips 135A and 135B may each be formed from a graphite brush (e.g., a carbon brush).

[0040] The nut assembly includes a cylinder 149, mounts 128A and 128B, a guide pin 132, an upper cover 129 / fixing ring 145 that secures the guide pin 132 to the cylinder 149 in place, and a ring-shaped base 151 that secures the cylinder 149 to the handle portion 108 in place so that the nut assembly does not move relative to the handle portion 108.

[0041] Screw 124 has a torque receiving structure 150 (For example, a shaft or prism) The screw 124 is rotated by the rotary motor 107 via the ball bearing 142, allowing it to move freely up and down while rotating. The screw 124 is fitted to the load member 103 via the ball bearing 142, and the screw can transmit reciprocating motion to the load member 103 without the screw transmitting its rotational motion to the load member 103.

[0042] The load member 103 includes an inner sleeve and an outer sleeve, the inner sleeve having an opening 156 and the outer sleeve having a corresponding straight guide groove 144, the straight guide groove 144 engaging with a guide ridge 148 of a nut to provide additional stability to the load member 103 when it is pulled up or down. A pair of conductive strips 135A and 135B are arranged along the outer surface of the inner sleeve, and a pair of conductive scrapers 147A and 147B may protrude between the inner and outer sleeves of the load member 103. The nested nature of the inner sleeve within the outer sleeve may help to press the conductive scrapers 147A and 147B against the conductive strips 135A and 135B to make good electrical connections.

[0043] Figure 10 is a cross-sectional view showing the reciprocating stimulation device 100A of Figures 8 and 9. As shown in this figure, the handle portion 108 includes a battery 110, a PCB 118, a shell 119, a charging port 120, buttons 111A and 111B, and a rotary motor 107. Torque receiving structure 150 (For example, a shaft or prism) The motor 107 transmits rotational force to the screw 124 and allows the screw 124 to move freely up and down. The screw has a double helical groove 131. The retractable tube 106 connects the outside of the handle 108 to the outside of the stimulator body 102. The cylinder 149 holds the guide pin 132 in place, and the nut includes a pair of mounts 128A and 128B. The upper cover 129 fits the guide pin 132 into the cylinder 149. The load member includes an inner sleeve 136 and an outer sleeve 126. The ball bearing 142 fits the screw 124 into the load member including the sleeves 126 and 136, allowing the screw 124 to rotate freely. The support 127 fits into the load member and includes a chamber 139 for wiring from the conductive subassembly to the vibration motor 137 to pass through the first hole 138 of the case 125.

[0044] Figure 11 is another cross-sectional view showing the reciprocating stimulator 100A of Figures 8, 9, and 10. As shown in this figure, there is a cross-section "A" which is enlarged in Figure 12. Thus, Figure 12 is an enlarged view of what is shown in cross-section "A" of Figure 11. According to this figure, an outer sleeve 126 is visible inside the stimulator body 102. Between the outer sleeve 126 and the inner sleeve 136, the arched contact 146 of the conductive scraper 147B is pressed against the conductive strip 135B to make electrical contact. The upper cover 129 is fixed to the cylinder 149 and this pair does not move. The screw 124 is shown as having a double helical groove 131.

[0045] Figure 13 is a cross-sectional view of a reciprocating stimulation device 100B according to an exemplary embodiment of the present invention. In this configuration, the top of the screw 124 is directly coupled to the load member 103, so that the screw moves up and down but does not rotate. Instead, the nut 122 is held in place within the handle portion 108 in the vertical direction, but can rotate freely. The rotational force of the motor 107 is transmitted to the torque receiving structure 150. (For example, a shaft or prism) A device is used to rotate the nut 122, and the rotation of the nut 122 pushes the screw 124 up or down without rotating the screw 124. Any one or more elements of the device not described in detail with respect to this figure or other figures should be assumed to be analogous to the corresponding elements described elsewhere in this disclosure.

[0046] Figure 14 is an exploded view of the reciprocating stimulation device 100B shown in Figure 13. Here, the screw 124 is located within an external sleeve 126. Therefore, in this configuration, the screw 124 does not rotate; rather, the nut assembly rotates, allowing the screw 124 to move up and down. The nut assembly includes a guide pin 132 that engages with the double helical groove 131 of the screw 124. The container 152 engages with the guide pin 132, so that when the container 152 rotates, the guide pin 132 rotates, and therefore, as the guide pin 132 rotates within the groove of the screw, the guide pin 132 pushes the screw 124 up and down. A retaining ring 145 secures the guide pin 132 to the container 152. Therefore, when the container 152 rotates around the screw 124, the guide pin 132 rotates, causing the screw to exhibit reciprocating motion. Torque receiving structure 150 (For example, a shaft or prism) The motor 107 transmits its rotational motion to the container 152. The inner sleeve 136 encloses the container 152, but does not rotate as it is fixed to the stationary casing of the motor 107. The outer sleeve 126 is positioned around the inner sleeve 136, and as the conductive strips 135A and 135B carry power, the outer sleeve 126 is raised and lowered away from the inner sleeve 136. One or more raised guide lines 148 of the outer sleeve 126 engage with corresponding straight guide grooves 144 (see, for example, Figure 9) of the inner sleeve 136 to provide stability as the outer sleeve 126 rises and falls relative to the inner sleeve 136. The container 152 has the shape of an outer cylindrical shell and an inner cylinder (e.g., a “limited post” 155) concentric with it. The outer cylindrical shell encloses the screw 124, and the limited post 155 is located inside the limited chamber 153 of the screw. The outer shell of the container 152 and the limited post 155 are torque receiving structure 150 (For example, a shaft or prism) The containers 152, each containing a polygonal opening, are connected to each other by a bottom cap. In this way, the rotational force of the motor 107 rotates the containers 152.

[0047] The limited chamber 153 is located inside the screw and is shaped to receive the limited post 155, allowing the vessel 152 to rotate freely around the screw 124.

[0048] The bottom cap of the container 152 may include, for example, a hexagonal opening. As described above, the torque receiving structure 150 (For example, a shaft or prism) The screw 124 is positioned within the opening of the bottom cap of the container 152 and rotates the container 152 around the screw. As the container 152 rotates around the screw, the screw 124 moves up and down by the guide pin 132 which is rotated by the container 152. The bottom cap of the container 152 may include one or more vents to allow air to freely enter and exit the space between the container 152 and the screw 124.

[0049] Figure 15 is an exploded view of the reciprocating stimulation device 100B shown in Figures 13 and 14. Here, we can see that the motor 107 is bonded to the internal sleeve 136, and the support 127 surrounds the internal sleeve 136. The spring-shaped pipeline 154 is electrically connected to the conductive strips 135A and 135B, from which it receives power, transfers the power through wiring running through the support 127, and is connected to the vibration motor 137 in the case 125 through the aforementioned first hole.

[0050] Figure 16 is a cross-sectional view of the reciprocating stimulation device 100B shown in Figures 13, 14, and 15. Here, the engagement of the container 152 around the screw 124 can be clearly seen. The method of electrical connection from the conductive strip 135B to the spring-shaped pipeline 154 is also visible.

[0051] Figure 17 is an exploded view of a reciprocating stimulation device 100B according to an exemplary embodiment of the present disclosure. This configuration may be similar to the configurations shown in Figures 13-16, except for the configuration of the conductive subassemblies. Therefore, where the description of one or more elements in this figure or other figures is omitted, it can be understood that it is similar to the corresponding elements described in detail with respect to at least the other figures.

[0052] Here, a pair of conductive scrapers, represented by at least 147B, contact a corresponding pair of conductive strips 135A and 135B, thereby supplying power to the vibration motor 137 in the stimulation component 101 via wiring that may extend from the vibration motor to the conductive scrapers. Again, the conductive scrapers can maintain electrical contact with the conductive strips between the internal and external sleeves, even when the conductive scrapers are attracted to the conductive strips, moving away from and towards them. Electrical contact can be made using one or more raised contacts on the conductive scrapers. The conductive strips can be made to have a more definite connection with the conductive scrapers using permanent magnets made of rubidium or the like. The conductive strips can be connected to a battery / power supply by additional wiring.

[0053] Figure 18 is another cross-sectional view showing the reciprocating stimulator 100B of Figures 13-17. As shown in this figure, there is a cross-section "B" which is enlarged in Figure 19. Thus, Figure 19 is an enlarged view of what is shown in cross-section "B" of Figure 18. In this figure, the interior of the screw 124 (e.g., the limited chamber) is visible, with the limited post 155 located inside it. The container 152 is shown with the retaining ring 145 engaged with the top of the container 152. The inner sleeve 136 is shown around the container, and the outer sleeve 126 is shown around the inner sleeve 136. Between the inner sleeve 136 and the outer sleeve 126 is shown a conductive strip 135B that contacts the conductive scraper 147B. All these components are located inside the stimulator body 102.

[0054] Figure 29 is an exploded view of the components of the reciprocating stimulation device shown in Figures 13-19. In Figure 29, the configuration of the outer sleeve 126 can be seen more clearly. The outer sleeve 126 fits around the inner sleeve 136, and the guide pin 132 engages with the groove of the screw 124. The screw 124 is coupled to the outer sleeve 126 via the inner sleeve 136, and as the screw 124 rotates, the outer sleeve 126 exhibits reciprocating motion, which is transmitted to the support 127 and the stimulation component 101. Figure 20 is a cross-sectional view of the reciprocating stimulation device 100C according to an exemplary embodiment of the present invention. Similar to the configuration in Figure 13, the top of the screw 124 is directly coupled to the load member 103, so that the screw moves up and down but does not rotate. Instead, the nut 122 is held in place relative to the motor 107 in the vertical direction, but can rotate freely. The rotational force of the motor 107 is used to rotate the nut 122, and the rotation of the nut 122 pushes the screw 124 up or down without rotating the screw 124. Any element of a device not described in detail in this or other figures should be assumed to be similar to a corresponding element described elsewhere in this disclosure. Conductive subassembly 104 may be omitted in this configuration.

[0055] Figure 21 is a cross-sectional view of a reciprocating stimulation device 100D according to an exemplary embodiment of the present invention. According to this approach, the rotary motor 107 is located in the top section of the device 100D, for example, in the stimulation body 102 and close to the stimulation component 101. The power supply / battery 110 is still located in the handle portion 108, and the first conductive subassembly 104A is used to carry power from the battery 110 to the rotary motor 107. The second conductive subassembly 104B is still used to carry power from the battery to the stimulation component 101. The rotary motor 107 can rotate the screw 124 from the top, rather than from the bottom as shown in other configurations. The nut 122 is fixed to the handle portion 108 of the device 100D, and in this configuration, the nut 122 is fixed in place so as not to rotate. Thus, as the screw 124 rotates within the stationary nut 122, the screw is pushed and pulled against the nut, creating a reciprocating motion. The moving screw 124 pushes the rotary motor 107 inside the stimulator body 102, so that the device 100D extends and retracts. A guide member 123 extending between the nut 122 and the retaining ring inside the stimulator body 102 is used to add stability as the device 100D exhibits reciprocating motion. Again, the nut 124 may be threaded with a double helical groove that meets at the top and bottom, so that the movement can be bidirectional while the rotary motor 107 rotates in only one direction.

[0056] Figure 22 is a cross-sectional view of a reciprocating stimulation device 100E according to an exemplary embodiment of the present invention. According to this approach, the handle portion 108 may be substantially similar to that shown in Figure 20, having a rotating nut 122 driven by a rotary motor 107. The rotating nut 122 moves the screw 124 up and down, thereby causing the load member 103 to reciprocate. The stimulation body 102 here has a cup shape including an elongated channel 158 with an open end. According to this approach, the expandable tube 106 may be omitted. A guide member 123 may also be used here, as shown, to add stability to the screw 124 and load member 103. Again, the nut 124 may be threaded with a double helical groove that meets at the top and bottom, so that movement can be bidirectional while the rotary motor 107 rotates in only one direction.

[0057] Figure 23 is a perspective view showing the container 152 described above (see, for example, Figure 14). As can be understood from the above, the container 152 includes an outer cylindrical shell with a limited post 155 and a container groove 160 at its center. The top opening of the container 152 can be screwed in by a screw 124. A vent hole 161 is visible in its bottom cap.

[0058] Figures 24, 25, 26, and 29 show exemplary embodiments of the reciprocating stimulation device of Figure 21. In these figures, Figure 24 is a perspective view, Figure 25 is an exploded view of the components, and Figure 26 is a cross-sectional view. Figure 29 is an exploded view of the components. As can be seen from Figure 24, the reciprocating stimulation device includes a stimulation body 102 connected to a handle portion 108 by an expandable tube 106. The handle portion 108 includes a charging port 120 and a button 111. As can be seen from Figure 25, the shell 117 encloses a battery 110 and together a rotary motor 107 and a vibrating motor 137. A screw 124 is coupled to the rotary motor 107, and in one embodiment, the rotary motor 107 is a bidirectional motor (For example, a dual-shaft motor)The outer sleeve 126 is held on the screw 124 by a fixing member 145. A guide pin 132 engages with a double helical groove 131 of the screw 124. The inner sleeve 136 is positioned on the screw 124, and as the screw 124 is rotated by the rotary motor 107, the guide pin 132 moves in a reciprocating manner, thereby pushing the stimulator body 102 toward and away from the outer sleeve 126 together with the handle 108.

[0059] The guide pin 132 may be part of a guide member assembly that includes a straight guide hole having a corresponding protrusion, thereby enabling the guide pin 132 to be held in the correct position.

[0060] This mechanism can be fully understood from Figure 26. In Figure 26, the conductive assembly 104 is connected to the button 111 and the charging port 120, and the rotary motor 107 is located inside the stimulator body 102. (For example, a dual-shaft motor) Further details are visible, including the establishment of electrical connections to various electrical components such as the vibration motor 137 and the battery 110. In other respects, the configurations in these figures may be similar to those shown in at least Figure 21. As can be understood from Figure 26, the bidirectional motor 107 or vibration motor 137 is located within the stimulator body 102. The stimulator body 102 is configured to be inserted into various parts of the human body, such as the vagina or anus. When the stimulator body 102 is inserted into the human body with the reciprocating stimulator device, the rotation of the screw 124 and the fixation of the external sleeve 126 by the grip of the hand or muscles cause the stimulator body 102 to move continuously back and forth within the human body while providing vibration stimulation under the action of an eccentric wheel.

[0061] Figure 28 is an exploded view of the components of the reciprocating stimulation device of Figure 21, in an alternative configuration of Figures 24-26. As can be clearly seen from this figure, the guide pin 132 extends through an opening in the internal sleeve 136 and engages with a groove in the screw 124, and the guide pin is held in place relative to the internal sleeve 136 by a guide member 123. In this way, the rotation of the screw 124 causes the guide pin 132 to move in a reciprocating manner, as the rotation of the guide pin 132 is prevented by the guide member 132, and the external sleeve 126 is pushed and pulled by the reciprocating motion of the pin 132. The external sleeve 126 is fixed to a handle portion 108, which is not shown in this figure for the sake of simplified explanation.

[0062] Figure 27 is a cross-sectional view of another configuration of the reciprocating stimulation device of Figure 22. According to this approach, the stimulation body 102, which includes the elongated channel 158, does not need to be coaxial with the handle portion 108, but can instead extend parallel to it. The load member 103 can transmit the reciprocating motion from the screw 124 to the stimulation body 102. In other respects, the configuration of this figure may be similar to at least that shown in Figure 22. The exemplary embodiments described herein are exemplary, and many modifications can be introduced without departing from the spirit of the disclosure or the claims. For example, elements and / or features of different exemplary embodiments can be combined and / or substituted for each other within the scope of this disclosure and claims.
