Abstract

Embodiments of the present disclosure disclose a sexual stimulation device. The sexual stimulation device includes a body, a drive member disposed within the body, a sexual stimulator having a spiral structure rotatably coupled to the drive member, and a covering member adapted to wrap the spiral structure. The spiral structure wrapped by the covering member is adapted to be inserted into erogenous zones of a user's body. The rotational movement of the spiral structure relative to the covering member forms an undulation on at least a portion of the covering member without ripping the covering member, thereby providing undulating stimulation to the erogenous zone of the human body.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Chinese Patent Application No. 202421242692.6, filed on Jun. 3, 2024 before the China National Intellectual Property Administration, the disclosure of which is incorporated herein by reference in entirety. TECHNICAL FIELD The present disclosure relates to sexual aid devices and, more particularly relates, to a sexual stimulation device for engaging and sexually stimulating the user's body, particularly the female genitals. BACKGROUND Massage stimulation devices mimic various human massage techniques to target specific areas of the user's body. These devices are typically used in electronic toys, medical equipment, massage tools, and other applications. Current massage devices use reciprocal telescoping, rotating, or pressing movements to provide massage or sexual stimulation to erogenous zones of a user's body. One such massage device 100, as shown in FIG. 1, mainly includes a handle, a drive member disposed within the handle, and a reciprocating motion structure. The reciprocating motion structure has a spindle 102, a guide shaft 104, one or more action beads 106, and a suspension support structure. A plurality of inclined and closed-loop construction of track ring grooves 108 are spaced apart along a circumferential wall surface of the spindle 102 along an axial direction. The guide shaft 104 is positioned on one side of the spindle 102, in a state parallel to the spindle 102. The one or more action beads 106 are mounted to the guide shaft 104 and adapted to be engaged with track ring grooves 108 through sliding or rolling contact. As the spindle rotates using the drive member, the one or more action beads 106 reciprocate along the axial direction of the guide shaft 104. The suspension support structure, which is slidingly positioned, facilitates this movement. The suspension support structure is positioned slidably between the one or more action beads 106 and the guide shaft 104. It applies an elastic force to the guide shaft 104, thereby keeping the one or more action beads 106 suspended against the circumferential wall of the guide shaft 104. Additionally, the spindle 102 of the reciprocating motion structure is connected to the drive member's driving end. The massage device further includes a case and a silicone sleeve. The case is attached to the handle houses the reciprocating motion structure. It features an opening through which the one or more action beads 106 are exposed. A silicone sleeve is fitted within the case and comes into contact with the one or more action beads 106. Unlike previous designs where the entire movement experienced sliding friction with the silicone sleeve, the structure disclosed in FIG. 1 reduces the friction area between the one or more action beads 106 and the silicone sleeve. This reduction in friction lowers heat generation, thereby extending the service life of the silicone sleeve. However, this design requires additional space for the guide shaft 104, faces issues in installing the one or more action beads 106, and complicates the assembly process. Furthermore, as the one or more action beads 106 move only vertically along the spindle due to the track ring grooves, the massage effect is limited, leading to a suboptimal user experience. Therefore, there exists a need for a massage stimulation device with an improved mechanism of movement to enhance sexual arousal on the user's body.

In an embodiment, a sexual stimulation device is disclosed. The sexual stimulation device includes a body, a drive member disposed within the body, a sexual stimulator having a spiral structure adapted to be operably coupled to the drive member to allow a rotational movement thereof, and a covering member adapted to wrap the spiral structure. The spiral structure wrapped by the covering member is adapted to be inserted into erogenous zones of a user's body. The rotational movement of the spiral structure relative to the covering member forms an undulation on at least a portion of the covering member, without ripping the covering member, thereby providing undulating stimulation to the erogenous zone of the human body. In another embodiment, a sexual stimulation device is disclosed. The sexual stimulation device includes a body, a drive member disposed within the body, a sexual stimulator having a spiral structure adapted to be operably coupled to the drive member to allow a rotational movement thereof, and a covering member.
