Description

TECHNICAL FIELD

[0001] The present utility model belongs to the technical field of massage and relates to a technology for improving the massage effect and rehabilitation effect. In particular, it concerns a massage module and a device for internal massage. TECHNICAL BACKGROUND

[0002] Women often experience various complications after childbirth, one common consequence being pelvic floor muscle relaxation. As we all know, pregnancy and childbirth can lead to pelvic floor muscle relaxation in women, which can cause symptoms such as vaginal wall protrusion, urine leakage, and pelvic floor organ prolapse. Therefore, women should undergo timely rehabilitation and treatment of pelvic floor muscles after childbirth. Currently, there are two types of postnatal rehabilitation tools: One involves stimulating the vaginal muscles by vibrating the insulating rod; The other is a vaginal mucosa repair model, in which the massage ball shrinks and expands through pneumatic pressure to achieve massage stimulation of the massage elements in the body; however, the massage stimulation points formed by this massage ball are relatively tight and concentrated, which reduces the massage effect. CONTENT OF THIS APPLICATION

[0003] In order to solve the above-mentioned technical problems, the present utility model provides a massage module and a device for massaging inside the body.

[0004] To achieve the above-mentioned purpose, the technical solution of the present utility model is: A massage module comprising at least the following: a main body part having a columnar body and a groove portion provided on the columnar body, wherein the main body part can be fully inserted into a hole-shaped part to be massaged; wherein the columnar body is a structure that fits the inner cavity of the hole-shaped part to be massaged; wherein the groove portion is formed by being recessed inwardly from the peripheral walls of one side or opposite sides of the columnar body, thereby forming an opening in at least one side of the columnar body; and a massage member having at least one massage projection, the massage projection being provided in the groove portion and projecting from the opening on the outer peripheral surface of the columnar body, the massage projection being freely movable in the groove portion.

[0005] The beneficial effects of the massage module and the device for internal massage of the present utility model are reflected in: First, the main body part can carry the massage element into the hole-shaped part to be massaged, so as to form a massage area in the inner cavity of the hole-shaped part to be massaged, which ensures more pronounced stimulation of the body and enables effective massage of the part to be rehabilitated; Secondly, the massage elements placed in the groove area have a larger range of motion and allow the tissue of the inner cavity to settle in the groove area to wrap around the massage element, so that it can bring a more intense massage stimulation effect to the inner cavity on the basis of not producing massage pain, and the radiated massage area is larger to ensure that the degree of sensation of the body is further improved. Third, the massage element consists of at least two small spheres. By pinching and kneading, sliding in one direction, or moving closer or further away from each other in both directions, the small spherical massage elements can achieve significant stimulation and a better massage effect on the human body cavity. Furthermore, the small spheres are installed in the groove area, so their degree of freedom in the radial direction of the main body part is enhanced, enabling multi-directional massage actions to enhance the massage effect and stimulate the body's sense of well-being.

DETAILED DESCRIPTION

[0007] Hereinafter, the technical solutions in the embodiments of the present utility model will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present utility model and not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments that general technical personnel can obtain without creative effort fall within the scope of the present utility model.

[0008] In the following, the specific embodiments of the massage module and the device for massaging inside the body of the present utility model are described with reference to Fig. 1 to 7 are described in detail. [Example 1]

[0009] As in Fig. 1 and Fig. 2, Fig. 3 and Fig. 4, the massage module provided by the first embodiment of the present utility model includes a main body part 1 and a massage element 3. The main body part 1 can be fully inserted into a hole-shaped part 2 to be massaged. The main body part 1 has a columnar body 10 and a groove portion 5 provided on the columnar body 10. An end of the main body part 1 provided with the groove portion 5 is generally arcuate and inclined upward. The groove portion 5 is formed by an inwardly directed recess from an outer wall of one side of the main body part 1, and the massage element 3 is arranged in the groove portion 5. In this embodiment, since the groove portion 5 is provided only on one side of the main body part 1, the main body part 1 has only one opening 103.

[0010] The columnar body 10 is a structure that fits the internal cavity of the hole-shaped part 2 to be massaged. It should be understood that this portion is an approximately cylindrical structure that corresponds to the internal cavity of the hole-shaped part 2 to be massaged, such as a cylindrical shape, a cylinder-like shape, or a square cylindrical shape with chamfered corners. The columnar body 10 can be fully inserted into a hole-shaped part 2 to be massaged, while simultaneously inserting the groove portion 5 into the aforementioned portion. Among them, the columnar body 10 has a front portion, a middle portion, and a rear portion. The groove portion 5 can be arranged in any portion, preferably near the rear portion, and another set of massage modules can be arranged within the front portion.For example, the front section can be arranged as an electric telescopic structure or an electric vibration structure.

[0011] The massage element 3 comprises a rod portion 31 and at least one massage projection 33 (also called a massage head) located on the upper side of the rod portion 31. The rod portion 31 protrudes outward from the opening 103 to support the massage projection 33 and drive the massage projection 33 to oscillate in the grooved area 5. The massage projection 33 has at least one massage surface 301 that can act on the inner cavity of the hole-shaped part 2 to be massaged (its peripheral wall forms the massage surface). During the movement of the massage element 3, the massage surface 301 acts on the inner cavity of the hole-shaped part 2 to be massaged. Furthermore, the massage projection 33 of the present utility model can produce a touching and pressing massage effect in point-like areas, thus creating a stronger stimulation sensation compared to a large-area massage.

[0012] The massage surface 301 is a curved surface that directly or indirectly acts on the hole-shaped part 2 to be massaged. When the massage protrusion 33 is in direct contact with the inner wall surface of the hole-shaped part 2 to be massaged, the peripheral wall surface of the massage protrusion 33 serves as a massage surface for massaging and stimulating the hole-shaped part 2 to be massaged. Specifically, the massage protrusion 33 can be rigid, soft, or soft-wrapped in a rigid form. The material of the massage protrusion 33 can be selected as needed. In this case, since there is no insulation between the massage protrusion 33 and the hole-shaped part 2 to be massaged, the skin or tissue of the hole-shaped part 2 to be massaged can be wrapped or partially wrapped around the massage protrusion 33.During the massage process, the massage area directly generated by the massage protrusion 33 is larger, and the stimulation felt by the human body is stronger, which is beneficial for the rehabilitation of the hole-shaped part 2 to be massaged. Furthermore, the massage surface and the hole-shaped part 2 to be massaged can move relative to each other. That is, during the movement of the massage protrusion 33, relative sliding friction occurs between its peripheral wall surface and the inner wall surface of the hole-shaped part 2 to be massaged, thereby achieving a massage or stimulation effect.

[0013] Alternatively, the massage protrusion 33 may indirectly contact the inner wall surface of the hole-shaped part 2 to be massaged, that is, the massage protrusion 33 may be covered by a flexible layer 101. This flexible layer 101 may be a flexible layer that completely wraps around the peripheral wall surface of the main body part 1, or may be a flexible layer that covers the groove portion 5. The flexible layer 101 forms an action region 1011, and the massage protrusion 33 promotes the deformation of the action region 1011 of the flexible layer 101 in the groove portion 5. When the massage protrusion 33 performs a massage action, the wall surface of the flexible layer is caused to deform, thereby producing a massage stimulation effect. Among other things, the massage protrusion 33 may have some traces in its initial state, such as the formation of a small bulge or bulge on the flexible layer 101.At this time, the flexible layer 101 exerts a certain flexible binding force on the massage protrusion 33, thereby weakening the amplitude of the massage action to a certain extent; when the massage protrusion 33 performs a massage action, some of its traces become more visible, that is, the degree of deformation of the flexible layer 101 is gradually increased, thereby achieving the massage stimulation effect.

[0014] In this form, there is no relative sliding between the massage surface and the hole-shaped part 2 to be massaged, and the massage and stimulation action is carried out only by the massage projection 33, which drives the deformation of the flexible layer to achieve a relatively gentle massage stimulation and avoid secondary damage to the wound.

[0015] In cases with a more severe degree of injury, the massage protrusion 33 can be covered by the flexible layer 101, leaving traces visible or even invisible. The massage stimulation effect of these two methods is gentler and causes less secondary damage to the wound. In addition, the massage effect of the massage protrusion 33 is restricted by the flexible layer 101, which can avoid the problem of secondary wound tearing due to excessive massage amplitude. In cases with a lesser degree of injury, the massage protrusion 33 can be fully exposed. This shape has a better massage effect, and the massage protrusion 33 is not restricted and its movement amplitude is relatively large, which can bring greater stimulation.

[0016] Based on the above, the massage protrusion 33 has a visible state, a partially visible state, or an invisible state at least in the rest state. Among them, the visible state is that the massage protrusion 33 is completely exposed. In the visible view, the massage protrusion 33 is obviously independent of the main body part 1 or the groove portion 5 and there is no obstacle around it; the partially visible state is that the massage protrusion 33 is covered by the flexible layer 101 and partially has traces, and the invisible state is that the massage protrusion 33 is completely covered by the flexible layer 101 and is not exposed.

[0017] Preferably, the maximum radius of curvature R of the curved surface of the massage surface 30 is 15 to 10 mm. The range of the swing angle α when performing the swinging motion en by the massage projection 33 is 30° to 60°. By limiting the radius of curvature of the massage projection 33 within this range, it is possible to prevent the massage effect from being blocked due to an excessively large force-receiving area, and to prevent massage pain from increasing and comfort from decreasing due to the force-receiving area being excessively small. On the other hand, by optimizing the swing angle of the massage projection 33, it is possible to prevent a reduction in massage concentration and intensity due to an excessively large swing angle, and at the same time, it is also possible to prevent a reduction in the massage area due to an excessively small swing angle.The groove portion 5 is formed by recessing inwardly from one side or opposite side walls of the columnar body 10, and an opening 103 is formed on at least one side of the columnar body 10. Preferably, the groove portion 5 is integrally formed without changing the original radial dimensions of the main body part 1.

[0018] The massage protrusion 33 is provided in the grooved portion 5 and protrudes from the outer peripheral surface of the columnar body 10 through the opening 103. The massage protrusion 33 has an appropriate degree of freedom in the grooved portion 5. This degree of freedom allows the massage protrusion 33 to perform a gentle and moderately strong massage action. In this embodiment, the massage movement is a counter-rotating swinging movement or an up-and-down reciprocating movement.

[0019] In this embodiment, the massage element 3 can be driven by two types of drive. This means that the massage element 3 has two types of movement: The first is the oscillating motion. The massage element 3 has a certain degree of freedom in the grooved portion 5, which allows the massage elements 3 to oscillate toward each other along the longitudinal direction of the grooved portion 5. Specifically, the heads of the two massage protrusions 33 oscillate toward or away from each other, thereby achieving a clip-on massage effect. When multiple massage protrusions 33 oscillate, the massage area radiated by each massage protrusion 33 is the same as or similar to the body sensation stimulation felt when using a single massage protrusion 33. The difference is that a third massage area is formed between adjacent massage protrusions 33, and the massaged body located in the third massage area is kneaded by the adjacent massage protrusions 33, further increasing the stimulation.

[0020] In this oscillation mode, the oscillation drive assembly 40, as shown in Fig. 10, a swing motor 41 and a swing arm 43 connected to the swing motor 41. The swing arm 43 is connected to the massage protrusion 33. The swing arm 43 is pivotally connected to the inside of the main body part 1, and the swing arm 43 is driven to swing by the swing motor 41 to drive the massage protrusion 33 to swing (the opposite swing is a pinching motion). Since the swing mechanism is relatively mature in the prior art, it will not be described in detail here.

[0021] The second type is the reciprocating motion. Specifically, the massage protrusions 33 continuously exert force along the width direction of the main body part 1 on the hole-shaped part 2 to be massaged, thus providing a relatively strong stimulating body sensation.

[0022] In this movement mode, a lifting drive assembly (not shown) is provided in the main body part 1. The lifting drive assembly includes a lifting motor, a cam connected to the lifting motor, and a lifting arm abutting the cam. The lifting arm is connected to the massage projection. The lifting motor drives the cam to rotate, thereby intermittently lifting the lifting arm, thereby realizing the lifting action of the massage projection 33. Since there are many mechanisms for providing the lifting action in the prior art, they will not be described in detail here.

[0023] When the massage protrusion 33 performs a massage action, a certain action space is provided for the massage protrusion 33 because the grooved portion 5 is recessed to a certain depth M along the radial direction of the main body part 1. The increased action space means that the massage protrusion 33 has a higher degree of freedom. When the massage protrusion 33 performs massage stimulation in the grooved portion 5, it is found to have the following advantages: First, part of the structure of the massage protrusion 33 (part or all of the shaft of the massage protrusion 33) is hidden in the groove portion 5. When the length of the massage protrusion 33 is fixed, the massage protrusion 33 mounted in the groove portion 5 (hereinafter referred to as the former) is compared with the massage protrusion 33 mounted on the peripheral wall of the main body part 1 (hereinafter referred to as the latter): The former bulges the female hole-shaped part 2 to be massaged to a lesser extent, that is, the degree of deformation when the female hole-shaped part 2 to be massaged is smaller. This means that during the period when the main body part 1 enters the female hole-shaped part 2 to be massaged and in the massage period after entry, the damage to the female hole-shaped part 2 to be massaged is less, thus avoiding secondary damage to the female hole-shaped part 2 to be massaged. The latter bulges the female hole-shaped part 2 to be massaged to a greater extent, resulting in severe damage to the inner wall of the female hole-shaped part 2 to be massaged during the entry and massage period of the main body part 1, which is not conducive to the rehabilitation of the female after childbirth. Second, when the massage protrusion 33 can curve the female hole-shaped part 2 to be massaged to a certain extent, the length of the massage protrusion 33 installed in the groove section 5 (hereinafter referred to as the former) is compared with the massage protrusion 33 mounted on the peripheral wall of the main body part 1 (hereinafter referred to as the latter). The length of the former can be set to be longer. When the massage protrusion 33 performs a massage action, especially when performing a swinging massage action, it can perform massage actions in multiple directions and radiate a larger massage area to strengthen the massage effect and stimulation. Therefore, since the latter is relatively short, when performing massage movements, especially swinging movements, the radiated massage area is smaller and the massage effect is weaker. [Example 2]

[0024] In the following, the solution of the second embodiment of the present utility model is described with reference to Fig. 5. In the following description, elements having the same structure and function as those in the first embodiment are denoted by the same reference numerals, and a detailed description thereof is omitted.

[0025] The massage module 100a of this embodiment includes a main body portion 1a, two groove portions 5a recessed inward from both opposite side walls of the main body portion 1a, and a massage element 3a disposed in the groove portion 5a. In this embodiment, the two groove portions 5a are arranged to penetrate each other, thereby forming an opening 103a on both sides of the main body portion 1a. In this embodiment, the massage element 3a includes two massage columns 30a, each protruding outward from the openings 103a on both sides of the main body portion 1a. Each massage column 30a has small spherical massage protrusions 33a at both ends. That is, the massage element 3a includes four small spherical massage protrusions 33a disposed on opposite sides of the main body portion 1a.

[0026] In this embodiment, the two massage columns 30a slide back and forth along the longitudinal direction of the groove area 5a (see Fig. 5) or away from each other (see Fig. 6). At this time, the massage protrusions 33a at both ends exert sliding massage and stimulation effects on the walls of the human body cavity. Likewise, the massage protrusions 33a located on both sides of the main body part 1a may be covered by a flexible layer 101. The flexible layer 101 may be a flexible layer that completely wraps around the peripheral wall surface of the main body part 1, or may be a flexible layer that covers the opening 103a of the groove portion 5a. The flexible layer 101 forms an action region 1011, and the massage protrusion 33a promotes the deformation of the action region 1011 of the flexible layer in the groove portion 5a. When the massage protrusion 33a exerts a massage action, the wall surface of the flexible layer is caused to deform, thereby producing a massage stimulation effect.

[0027] In this bidirectional sliding movement, as in Fig. 11, a slide drive assembly 50 is provided in the main body part 1a. The slide drive assembly 50 may include a telescopic motor 51, a threaded rod (transmission rod) 53 connected to the telescopic motor 51, and a threaded sleeve 55 screwed onto the threaded rod 53. The two massage columns 30a are connected to the threaded sleeve 55 (a through groove is provided on the bottom surface of the groove portion 5a for connection between the two), and the telescopic motor 51 drives the threaded rod 53 to rotate.In this embodiment, since the threaded rod 53 includes a first threaded rod and a second threaded rod, the spiral directions of the thread grooves (not shown) formed by the outer surfaces of the first threaded rod and the second threaded rod are opposite; the first threaded rod passes through one of the massage columns 30a, and the second threaded rod passes through the other massage column 30a; the telescopic motor 51 can rotate intermittently clockwise or counterclockwise and drive the threaded rod 53 to rotate synchronously.

[0028] When the telescopic motor 51 rotates clockwise, the two massage columns 30a, each mounted on the first threaded rod and the second threaded rod, move toward each other; when the telescopic motor 51 rotates counterclockwise, the two massage columns 30a, each mounted on the first threaded rod and the second threaded rod, move away from each other. Therefore, the massager using the massage module 100a of this embodiment can achieve a better massage effect for users. [Example 3]

[0029] In the following, the solution of the third embodiment of the present utility model will be described with reference to Fig. 7 and Fig. 8. In the following description, elements having the same structure and function as those in the first embodiment are denoted by the same reference numerals, and a detailed description thereof will be omitted.

[0030] The massage module 100b in the third embodiment of the present invention includes a main body portion 1b, two groove portions 5b recessed inward from both opposite side walls of the main body portion 1a, and a massage element 3b disposed in the groove portion 5b. In this embodiment, the two groove portions 5b are arranged to penetrate each other, forming an opening 103b on each side of the main body portion 1b. The massage element 3b includes only one massage column 30b. The two ends of the massage column 30b protrude from the openings 103b on each side of the main body portion 1b, and small spherical massage protrusions 33b are formed at their ends. Similarly, in this embodiment, the massage protrusions 33b located on each side of the main body portion 1b may be covered by a flexible layer 101.This flexible layer 101 may be a flexible layer completely wrapped around the peripheral wall surface of the main body part 1, or may be a flexible layer covering the opening 103b of the groove portion 5b. The flexible layer 101 forms an action region 1011, and the massage protrusion 33b promotes the deformation of the action region 1011 of the flexible layer in the groove portion 5b. When the massage protrusion 33b performs a massage action, the wall surface of the flexible layer 101 is caused to deform, thereby producing a massage stimulation effect.

[0031] In this embodiment, the massage column 30b performs a linear reciprocating movement along the longitudinal direction of the main body part 1b in two mutually penetrating groove areas 5b. The massage projections 33b at both ends exert sliding massage and stimulation effects on the walls of the human body cavity.

[0032] In this one-way sliding movement mode, the main body 1b is equipped with a sliding drive assembly 50 similar to the sliding drive assembly described in the second embodiment. The only difference is that the spiral direction of the threaded groove (not shown) formed on the outer surface of the threaded rod 53 is the same. One massage column 30b is connected to the threaded sleeve 55. In this embodiment, the telescopic motor 51 drives the threaded rod 53 to rotate, whereby the threaded sleeve 55 drives the massage projection 33 to perform a linear reciprocating movement. Of course, this structure is only one of the specific structures provided in this embodiment. Since there are many linear reciprocating movement mechanisms in the prior art, it will not be described in detail here.

[0033] The movement process of the above-mentioned embodiments 1 to 3 results in a variety of action modes for the massage projections 33, 33a, and 33b. Regardless of the action mode selected, however, the groove portions 5, 5a, and 5b can provide a certain degree of freedom for the massage projections 33, 33a, and 33b, thereby reducing the binding force on the massage projections 33, 33a, and 33b to cause them to perform the massage action more intensively.

[0034] It is understood that in the above-mentioned first to third embodiments, the massage protrusions 33 can be formed into small balls, hemispheres, rounded blocks, columns, tongue-shaped bodies, etc., and their shapes are not limited as long as they do not damage the user's cavity during the massage operation.

[0035] It is understood that the groove portions 5, 5a, and 5b may have regular shapes, such as a rectangle, a circle, or an oval, or irregular shapes, which are not specifically limited here. As long as they are structures with grooves on the peripheral walls of the main body portions 1, 1a, and 1b, they all fall within the scope of this application.

[0036] Furthermore, it is understood that the massage columns 30a and 30b of the massage modules 100a and 100b relating to the above-mentioned second and third embodiments can also realize a linear reciprocating movement along the width direction of the groove portions 5a and 5b by the lifting motor and the lifting arm as described in the first embodiment, thereby again applying hole-shaped touch massage effects to the inner cavity walls of the hole-shaped parts 2 to be massaged on both sides.

[0037] It is understood that the size of the groove area determines the area of ​​action of the massage protrusion to some extent. Although the area of ​​action correlates positively with the stimulation of body sensation, the following two points must be considered: Firstly, as the area of ​​action increases, the massage area radiated by the massage protrusions also increases, which increases the risk of the massage protrusions touching the wound. Secondly, although the groove area improves the degree of freedom of the massage protrusion to a certain extent, if the degree of freedom is too high, it will lead to excessive stimulation of the internal cavity and thus massage pain.

[0038] Based on this, the depth M of the groove portions 5, 5a, and 5b is preferably in the range of 8 to 20 mm; the angle between the inner wall surface and the bottom surface of the groove portions 5, 5a, and 5b is in the range of 90° to 135°.

[0039] Within this value range, the degree of freedom that the grooved portion can exert on the massage protrusion is within the expected range, so its action space is limited; when the massage protrusion is retracted to the outermost position, the grooved portion provides a certain degree of restraint, which limits the massage area radiated by the massage protrusion to a certain extent, thereby reducing the risk of secondary injury caused by too large a massage area and making the stimulation effect of the massage protrusion more concentrated to ensure the degree of stimulation of the body feeling.

[0040] As in Fig. 5, the internal body massage device 200 using the massage module 100 shown in the first embodiment includes at least one massage body 20. The massage body 20 may be curved, straight, or wave-shaped, etc. In this embodiment, the massage body 20 has a curved shape with a raised front end.

[0041] The massage module 100 is located at the front end of the massage body 20 and represents the body entry end 21 of the massage body 20, which can be fully inserted into the hole-shaped part to be massaged. A handheld end 23 of the massage body 20 is formed away from the body entry end 21 for holding by the user.

[0042] As in Fig. 12 and Fig. 13 shown, shows Fig. 12 a schematic diagram of the Fig. 5, when massaging a human body; Fig. 13 shows a schematic diagram of the device for massaging inside the body 300 in a use state using the device shown in Fig. 5 and Fig. 6. By using different massage modules, the resulting internal body massage device can exert different massage effects on the human body and meet the needs of different groups of people.

[0043] The internal body massage device in the present utility model has all the beneficial effects of the aforementioned massage module 100, 100a, or 100b, which are not described in detail here. Furthermore, with regard to the internal drive principle of the internal body massage device 200, reference can be made to the principle of the oscillating mechanism or sliding mechanism of the massage module in question in the prior art, which is not described in detail here.

[0044] In describing embodiments of the present utility model, specific features, structures, materials, or properties may be combined in any suitable manner in one or more embodiments or examples.

[0045] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
