Description

Technical field

[0001] The present invention relates to the field of sex toys, in particular to a massage stick structure with internal suction function. State of the art

[0002] Existing massage wands primarily aim to locally stimulate women's sensitive points to achieve predictable mental pleasure. However, existing massagers generally use a single vibration motor for stimulation, making the stimulation relatively one-sided. After a period of use, the novelty is lost, which impairs the user experience.

[0003] Of course, there are also some sex toys that simulate a tongue by vibrating to stimulate sensitive spots. However, these primarily target the sensitive spots on the outside of the vagina and cannot penetrate the inside of the vagina, which impairs the user experience. Contents of the present invention

[0004] The objective of this invention is to propose a massage wand structure with an internal suction function, aiming to improve the structure of the massage wand so that it can be inserted into the vagina and also act on the vaginal opening. The internal suction structure achieves multi-layered stimulation of the sensitive points of the vagina, thereby enhancing the user experience.

[0005] To achieve the above-mentioned object, the invention proposes a massage stick structure with internal suction function, comprising: - a hard case provided with an interior space having at least one recess penetrating the side wall of the hard case; - a flexible wall, wherein the flexible wall envelops the peripheral wall of the hard case, the flexible wall covers the recess and forms an elastic part, a closed cavity is formed between the elastic part and the hard case; - a drive device, wherein the drive device is arranged in the hard housing, wherein a lithium battery, a circuit board connected to the lithium battery and a control unit connected to the circuit board are arranged in the hard housing, the drive device is connected to the circuit board, the control unit is designed to control the working state of the drive device; - wherein the drive device is designed to control the volume change of the closed cavity and to adjust the gas pressure in the closed cavity, - whereby the elastic part can deform between an expanded position and a contracted position when the gas pressure changes.

[0006] In actual design, the massager includes a hard casing and a flexible wall that encloses the hard casing. Therefore, the massager is preferably rod-shaped (e.g., elongated cylindrical structure, elliptical cylindrical structure, or spherical); the massager can be inserted into the vagina or positioned at the opening of the vagina. During use, the drive device can control the air pressure in the closed cavity, thus exerting predetermined stimulation on the vaginal opening (e.g., the clitoris) or the vaginal wall. The stimulation can be either the elastic feeling of the elastic part on the skin or the feeling of negative pressure (comparable to suction), which can stimulate different sensitive points in different locations and achieve different experiences. At the same time, the massager can simulate the feeling of an erect penis.

[0010] As in the Fig. 1 to 6, the massage stick structure with internal suction function includes: - a hard housing 1, the hard housing 1 is provided with an interior space 10, the interior space 10 is provided with at least one recess 2 penetrating the side wall of the hard housing 1; - a flexible wall 3, the flexible wall 3 envelops the peripheral wall of the hard case 1, the flexible wall 3 covers the recess 2 and forms an elastic part 30, the elastic part 30 and the hard case 1 together form a closed cavity 3a; - a drive device 4, the drive device 4 is arranged in the hard housing 1, a lithium battery 41, a circuit board 42 connected to the lithium battery 41 and a control unit 43 connected to the circuit board 42 are arranged in the hard housing 1, the drive device 4 is connected to the circuit board 42, the control unit 43 is designed to control the working state of the drive device 4; - The drive device 4 is designed to control the volume change of the closed cavity 3a and to adjust the gas pressure in the closed cavity; - wherein the elastic part 30 can deform between an expanded position and a contracted position when the gas pressure changes.

[0011] In the actual design, the massage stick comprises a hard casing 1 and a flexible wall 3 that encloses the hard casing 1. Therefore, the massage stick is preferably rod-shaped (e.g., elongated cylindrical structure, elliptical cylindrical structure, or spherical); the massage stick can be inserted into the vagina or positioned at the opening of the vagina. During use, the drive device 4 can control the air pressure in the inner space 10 and thus exert a predetermined stimulation on the vaginal opening (e.g., the clitoris) or the vaginal wall. The stimulus can be perceived by the elastic part 30 as an elastic skin sensation or a negative pressure suction sensation (comparable to suction), thereby stimulating various sensitive points in different locations and achieving different experiences. At the same time, the massager can simulate the feeling of an erect penis.

[0012] In terms of design, the interaction of the hard housing 1 and the flexible wall 3 allows the interior of the massage stick to form a closed cavity. The drive device 4 varies the air pressure in the closed cavity 3a. In a preferred embodiment, the hard housing 1 is provided with a first air inlet 300, which is controlled by a third valve to allow opening or closing, thereby achieving the expansion of the elastic part 30.

[0013] The recess 2 is a through-hole penetrating the side wall of the hard case 1. In this case, the deformation of the elastic part 30 and its manufacturing are relatively simple and inexpensive.

[0014] The recess 2 extends arcuately from the hard housing 1 toward the axis and forms an arcuate fixed wall 2b. The recess 2 is provided with a hole position 2d connected to the drive device 4. The closed cavity 3a can be located between the fixed wall 2b and the elastic part 30 or within the closed cavity 3a.

[0015] The drive device 4, the lithium battery 41, the circuit board 42 and the control unit 43 can be mounted in the interior 10 or at a location of the hard case 1 remote from the interior 10 (e.g., outer wall, floor, etc.) to fix them.

[0016] Of course, the closed cavity 3a can also be arranged between the elastic part 30 and the outer wall of the recess 2, wherein the closed cavity 3a is directly driven by the drive device 4.

[0017] As in Fig. 3, the interior space 10 and the elastic part 30 form the closed cavity 3a, ie the interior space 10 is the closed cavity 3a.

[0018] As in Fig. 4, the second chamber 12 is the closed cavity 3a.

[0019] As in Fig. 7, the driving device 4 controls the volume of the closed cavity 3a directly through the bore position 2d when the fixed wall 2b and the elastic part 30 form the closed cavity 3a.

[0020] In another embodiment, the interior space 10 can be divided by the partition wall 1c into a first chamber 11 and a second chamber 12, which are relatively independent of each other, thereby achieving a separate pressure change in the second chamber 12. If the second chamber 12 is a separate closed cavity 3a, the air inlet opening 51a and the air exchange port 51b are located in the second chamber 12.

[0021] Of course, the elastic part 30 can also be designed as a plate structure arranged separately in the recess 2 to achieve the deformation of the elastic part 30. In this case, however, the tightness and softness of the elastic part 30 are compromised.

[0022] In particular, the outer wall extends arcuately in both directions at the position of the recess 2. It can be understood that the height h is greater, thereby also increasing the deformation range of the elastic part 30. This increases the stimulation of the woman's sensitive areas, thus also increasing the suction amplitude.

[0023] The main reason for this is that the vaginal wall can come into contact with the elastic part 30. When the elastic part 30 is pressed inward, a negative pressure is created that sucks in the vaginal wall, thus increasing stimulation.

[0024] In particular, the cross-section of the recess 2 has a concave arc shape 2a.

[0025] In particular, the recess 2 is designed as a continuous through-hole 2c. Of course, the recess 2 can also be designed as a continuous through-hole 2c, which also has corresponding tactile and stimulating effects, but with less deformation and thus less sensory stimulation.

[0026] In particular, the recess 2 has a block-like, strip-like, or dot-like structure. Of course, the recess 2 can be designed in various shapes depending on actual needs, which also changes the degree of deformation. In this application, a block-like structure with an elliptical shape is used.

[0027] In particular, the hard case 1 is manufactured by one-piece injection molding of plastic, including the partition wall 1c and the recess 2, thereby improving its integrity.

[0028] In particular, two recesses 2 are provided, but three may also be provided in order to achieve different suction effects.

[0029] In particular, the two recesses 2 are arranged symmetrically on the peripheral wall of the hard housing 1.

[0030] In particular, the drive device 4 comprises an air pump 5 and a three-way solenoid valve 6, wherein the air pump 5 has a first fluid channel 51 and a second fluid channel 52. The three-way solenoid valve 6 is equipped with a first air valve 61, a second air valve 62, and a third air valve 63. The first fluid channel 51 includes a second air inlet opening 51a and an air exchange port 51b.

[0031] The air exchange connection 51b is connected to the interior 10.

[0032] The second air inlet opening 51a is connected to the second air valve 62, the first air valve 61 is connected to the outside of the hard case 1, the third air valve 63 is connected to the second fluid channel 52.

[0033] In actual use, the air pump 5 supplies the intended liquid into the internal space 10 through the first air valve 61, thereby deforming the elastic part 30 into the expanded position, then the first air valve 61 closes, then the air pump 5 pumps the liquid from the air exchange port 51b through the second fluid channel 52 to the third air valve 63 (at this time, the elastic part 30 is in a contracted state) and back into the internal space 10 through the three-way solenoid valve 6, at this time it is in an expanded state;

[0034] This realizes the pressure change between positive and negative pressure, whereby the volume of the closed cavity 3a is switched.

[0035] In particular, at the upper end of the flexible wall 3, a solid body part 7 extends, which has a third cavity 71 in which a vibration motor 72 is installed.

[0036] The upper wall of the hard case 1 is provided with a through-hole 73, through which a cable is connected to the circuit board 42 after passing through the through-hole 73 along the side wall of the interior 10. The vibration motor 72 can generate a different stimulation sensation in the sensitive area, thereby enhancing the user experience.

[0037] In particular, the hard housing 1 comprises a first side housing and a second side housing 1b that cooperate with each other. The first side housing 1a and the second side housing 1b are each provided with a first half-channel 10a and a second half-channel 10b. The inner walls of the first side housing 1a and the second side housing 1b are each provided with a first partition section 10c and a second partition section 11c.

[0038] The first partition portion 10c and the second partition portion 11c together form the partition wall 1c, which divides the interior of the hard case 1 into a first chamber 11 and a second chamber 12, thereby achieving the separation of the first chamber 11 and the second chamber 12.

[0039] In particular, the partition wall 1c is provided with a restricting hole 8 into which the first liquid channel 51 and the second liquid channel 52 of the air pump 5 protrude. It is preferable that the restricting hole 8 and the air pump 5 are arranged in an airtight manner.

[0040] In particular, the vibration motor 72 is arranged horizontally or vertically depending on the product, thereby changing the placement direction of the vibration motor.

[0041] Specifically, the lower peripheral wall of the hard case 1 is provided with at least one restricting groove 91, the flexible wall 3 is provided with a restricting part 92 that fits with the restricting groove 91, thereby ensuring the stable installation of the flexible wall 3 and ensuring the connection and tightness.

[0042] In particular, the flexible wall 3 is a one-piece injection-molded silicone layer, of course, the specific flexible wall 3 can also be a condom.

[0043] In particular, the lower part of the hard case 1 is the handle area 100, which facilitates the use of the massage stick.

[0044] In particular, the outer wall of the elastic part is provided with massage patterns 200 which are designed as recessed or raised structures.

[0045] In particular, the massage patterns are arranged in dots, stripes or patterns, which enables the detection and use of sensitive points and increases the stimulation of these points.

[0046] In particular, the hard housing 1 is designed in an elongated structure or consists of two connected spherical parts.

[0047] The elastic part 30 is provided with a plurality of annular sections 310 which are recessed into the outer wall of the elastic part 30, which provides a predetermined deformation direction and a deformation range which can be understood as a folding point, whereby the deformation becomes controllable.

[0048] The above is only a preferred embodiment of the present invention and does not limit the scope of the utility model of the present invention. Any equivalent structural changes made within the spirit of the present invention or directly / indirectly applied in other related technical fields are included within the scope of the utility model of the present invention.
