Description

Technical Field

[0001] The present invention relates to the field of sex toys, and particularly to an internal suction massage rod structure.

Background Art

[0002] Existing massage rods mainly provide local stimulation to the sensitive points of women to obtain a certain mental pleasure. However, existing massage rods mainly use a single vibration motor for stimulation, and their stimulation methods are relatively single. Moreover, after using them for a while, the novelty is lost, which affects the user experience.

[0003] Of course, there are also sex toys that use a vibrating simulated tongue to stimulate sensitive points. At that time, they mainly act on the sensitive points around the vagina and cannot be inserted into the vagina, which affects the user experience.

Summary of the Invention

[0004] The present invention aims to improve the structure of the massage rod so that it can be inserted into the vagina or act on the opening of the vagina, and proposes an internal suction massage rod structure that realizes multi-layer stimulation of sensitive points on the vagina by an internal suction structure, thereby further improving the user experience.

[0005] To achieve the above object, the present invention includes a rigid housing provided with a lumen and at least one recess on the side wall, a flexible wall covering the outer peripheral wall of the rigid housing, shielding the recess to form an elastic part, and surrounding a closed cavity between the elastic part and the rigid housing, and a driving device provided on the rigid housing and connected to a PCB board. The rigid housing is provided with a lithium battery, a PCB board connected to the lithium battery, and a control device connected to the PCB board. The control device controls the operating state of the driving device, and the driving device controls the volume change of the closed cavity and adjusts the gas pressure therein. When the gas pressure changes, the elastic part can deform between a position where it expands and a position where it contracts, and proposes an internal suction massage rod structure.

[0006] In the actual design, since the massage rod includes a rigid housing and a flexible wall covering the rigid housing, preferably, the massage rod is in an elongated shape "for example, an elongated columnar structure, an elliptical columnar structure, or a spherical shape", and the massage rod may be inserted into the vagina or arranged at the opening position of the vagina. During use, the driving device controls the air pressure change in the closed cavity, and further applies a predetermined stimulus to the opening of the vagina "for example, the clitoris" or the vaginal wall. Among them, the stimulus may be an elastic feeling against the skin of the elastic part, or a negative pressure adsorption feeling "which can be understood as inhalation", and further stimulates sensitive points at different positions, and further different experiences can be obtained. At the same time, experiencing the massage rod can simulate the feeling of the penis swelling.

[0012] As shown in FIGS. 1 to 6, the internal suction massage rod structure includes a rigid housing 1 provided with a lumen 10 and at least one recess on the side wall, a flexible wall covering the outer peripheral wall of the rigid housing, shielding the recess to form an elastic part 30, and enclosing a closed chamber 3a between the elastic part 30 and the rigid housing 1, and a driving device provided on the rigid housing 1 and connected to a PCB board. The rigid housing is provided with a lithium battery, a PCB board connected to the lithium battery, and a control device connected to the PCB board. The control device controls the operating state of the driving device. The driving device controls the volume change of the closed chamber 3a and adjusts the gas pressure therein. When the gas pressure changes, the elastic part 30 can deform between the position where it expands and the position where it contracts.

[0013] In the actual design, since the massage rod includes a rigid housing 1 and a flexible wall 3 covering the rigid housing 1, preferably, the massage rod has a striped shape "for example, a long columnar structure, an elliptical columnar structure, or a spherical shape", and the massage rod may be inserted into the vagina or arranged at the opening position of the vagina. During use, the driving device 4 controls the air pressure change in the inner cavity 1012, and further applies a predetermined stimulus to the opening of the vagina "for example, the clitoris" or the vaginal wall. Among them, the stimulus may be the elastic feeling of the elastic part 30 against the skin, or the negative pressure adsorption feeling "which can be understood as inhalation", and further stimulate sensitive points at different positions to obtain different experiences. At the same time, the massage rod can be experienced to simulate the feeling of the penis swelling.

[0014] In the design, by fitting the rigid housing and the flexible wall, the inside of the massage rod can be made into a closed cavity, and the driving device can realize the air pressure change in the closed cavity 3a. In a preferred embodiment, the rigid housing is controlled to open and close by a third valve, and an air intake port 300 that enables the expansion of the elastic part 30 is provided.

[0015] The recess is a through hole, and the through hole penetrates the side wall of the rigid housing. In this case, the degree of deformation and manufacturing of the elastic part are convenient, and the production cost is low.

[0016] The recess extends in an arc shape along the axial direction from the rigid housing, the recess forms an arc-shaped solid wall, and a hole position communicating with the driving device is provided in the recess. At this time, the closed cavity 3a may be located between the deformed wall and the elastic layer, or may be located in the closed cavity 3a.

[0017] Here, the driving device, the lithium battery, the PCB plate, and the control device may be provided in the inner cavity, or the rigid housing may be provided at a position away from the inner cavity "for example, the outer wall, the bottom, etc.", and it may be realized to fix it.

[0018] Of course, the closed cavity 3a is provided between the elastic part and the outer wall of the recess, and the driving device can also directly drive the closed cavity 3a.

[0019] For example, as shown in FIG. 3, the inner cavity and the elastic wall surround the closed cavity 3a, that is, the inner cavity is the closed cavity 3a.

[0020] For example, as shown in FIG. 4, the second chamber is the closed cavity 3a.

[0021] For example, as shown in FIG. 7, when the solid wall 2b and the elastic wall surround the closed cavity 3a, the driving device directly controls the volume change of the closed cavity 3a according to the hole position.

[0022] In other embodiments, the inner cavity 10 can be divided into a relatively independent first chamber 11 and a second chamber by a partition plate, and further, the air pressure change in the second chamber can be individually controlled. When the second chamber is the independent closed cavity 3a, the intake port and the exchange air port are located in the second chamber.

[0023] Of course, even if the elastic part is a sheet-like structure individually provided in the recess, the deformation of the elastic part can be realized, and the sealing property and the use flexibility at that time are affected.

[0024] Specifically, the outer wall at the position of the recess 2 extends in an arc shape in both side directions. When the height h becomes larger, the deformation section of the corresponding elastic part 30 also becomes larger. Further, it can be understood that when the stimulation to the female sensitive area increases, the suction width also becomes larger.

[0025] The main reason is that when the vaginal wall can be attached to the elastic part 30, when the elastic part 30 is recessed inward, negative pressure is generated on the vaginal wall, further adsorbing the vaginal wall and further enhancing the stimulating effect.

[0026] Specifically, the cross section of the recess 2 forms a concave arc 2a.

[0027] Specifically, the recess 2 is a through hole provided through. Of course, the specific recess 2 may also be a through hole provided through, and may exhibit the corresponding touch and stimulation, but the deformation width is small and the sensory stimulation is also small.

[0028] Specifically, the concave portion 2 exhibits a block structure, a stripe structure, or a dot structure. Of course, in a specific design, the concave portion 2 can be set to different shapes according to actual needs, and accordingly its degree of deformation changes. In this application, a block structure is adopted and it exhibits an elliptical shape.

[0029] Specifically, since the hard housing 1 is integrally injection-molded from plastic including the partition plate 1c and the concave portion 2, its integrity is better.

[0030] Specifically, two of the concave portions 2 are provided. Of course, specifically, three may also be provided, and different adsorption effects can be formed.

[0031] Specifically, the two concave portions 2 are symmetrically provided on the outer peripheral wall of the hard housing 1.

[0032] Specifically, the drive device 4 includes an air pump 5 and a three-way solenoid valve 6. The air pump 5 is provided with a first fluid passage 51 and a second fluid passage 52. The three-way solenoid valve 6 is provided with a first air valve 61, a second air valve 62, and a third air valve 63. The first fluid passage 51 includes an intake port 51a and an exchange air port 51b.

[0033] The exchange air port 51b communicates with the inner cavity 10.

[0034] The intake port 51a communicates with the second air valve 62. The first air valve 61 communicates with the outside of the hard housing 1. The third air valve 63 and the second fluid passage 52 communicate with each other.

[0035] During actual use, the air pump 5 sends a predetermined fluid into the inner cavity 10 through the first air valve 61, further deforms the elastic part 30 to an inflated position, and then closes the first air valve 61. After that, the air pump 5 sends fluid from the exchange air port 51b through the second fluid passage 52 to the third air valve 63 "at this time, the elastic part 30 is in a retracted state", and then sends it back into the inner cavity 10 through the three-way solenoid valve 6, and at this time it is in an inflated state.

[0036] Furthermore, the air pressure switching between the positive air pressure and the negative air pressure is realized, and furthermore, the volume switching of the closed cavity 3a is realized.

[0037] Specifically, a solid part 7 extends at the upper end of the flexible wall 3, a third chamber 71 is provided in the solid part 7, and a vibration motor 72 is provided in the third chamber 71.

[0038] A through hole 73 is provided in the top wall of the rigid housing 1. After the cable passes through the through hole 73, it is connected to the PCB board 42 along the side wall of the inner cavity 10. The vibration motor can provide different stimulation sensations in the sensitive area and improve the user experience.

[0039] Specifically, the rigid housing 1 includes a first side housing and a second side housing 1b that fit together. The first side housing 1a and the second side housing 1b are respectively provided with a first semi-circular groove and a second semi-circular groove. First partition parts and second partition parts are respectively provided on the inner walls of the first side housing 1a and the second side housing 1b.

[0040] The first partition part and the second partition part surround the partition plate 1c. The partition plate 1c divides the inside of the rigid housing 1 into a first chamber 11 and a second chamber 12, and further realizes the division of the first chamber 11 and the second chamber 12.

[0041] Specifically, the partition plate 1c is provided with a stopper hole 8 for accommodating the first fluid passage 51 and the second fluid passage 52 of the air pump 5. Preferably, the space between the stopper hole 8 and the air pump 5 is provided airtightly.

[0042] Specifically, the vibration motor is arranged in the horizontal or vertical direction, and for some products, the arrangement direction of the vibration motor is further changed.

[0043] Specifically, at least one stopper groove 91 is recessed in the outer peripheral wall of the lower part of the rigid housing 1, and the flexible wall 3 is provided with a stopper portion 92 fitted into the stopper groove 91, further ensuring the stable attachment of the flexible wall 3 and guaranteeing the bonding degree and sealing property.

[0044] Specifically, the flexible wall 3 is an integrally injection-molded silica gel layer. Of course, the specific flexible wall 3 may also be a condom.

[0045] Specifically, the lower part of the rigid housing 1 is a gripping part 100, which is further convenient for using the massage rod.

[0046] Specifically, a massage pattern 200 is provided on the outer wall of the elastic wall, and the massage pattern is a recessed structure or a protruding structure.

[0047] Specifically, the massage pattern is installed in a dot shape, a stripe shape, or a pattern shape, further realizing the identification and use of sensitive points and enhancing the stimulation to sensitive points.

[0048] Specifically, the rigid housing 1 has a long-shaped structure or consists of two connected spherical bodies.

[0049] The elastic part consists of a plurality of annular parts provided at intervals. The annular parts are recessed in the outer wall of the elastic part, further providing a predetermined deformation direction and deformation interval, that is, it can be understood as a folding bit, and thus the deformation can be controlled.

[0050] The above is only a preferred embodiment of the present invention, and therefore does not limit the patent scope of the present invention. Under the concept of the present invention, equivalent structural conversions made using the content of the specification and drawings of the present invention, or direct / indirect applications to other related technical fields are all included in the patent protection scope of the present invention.
