An abdominal massager with vibrating contact points

Abstract

This utility model relates to a vibrating abdominal massager, comprising a front cover, a housing, and a massage disc protruding from the surface of the housing. The massage disc is rotated by a drive mechanism installed inside the housing. Specifically, an acupressure head, higher than the surface of the massage disc, is provided on the housing outside the massage disc. The height of the acupressure head is compressible, and a vibration motor is installed inside the acupressure head. Both the vibration motor and the drive mechanism are controlled by an electronic control board inside the housing. This utility model adds a vibrating acupressure head to the massage disc, which can not only contact the human body surface with adaptive pressure but also generate high-frequency vibration through the built-in vibration motor, enhancing the acupressure effect and overcoming the shortcomings of traditional simple rotational abdominal massage, thus enriching the massage experience. In particular, the use of a highly compressible acupressure head design is unique in concept, simple in structure, and incorporates contact vibration.

Description

Technical fields:

[0001] This utility model belongs to the field of massage equipment technology, and specifically relates to an abdominal massager with vibrating contact points. Background technology:

[0002] Most existing abdominal massagers consist of a massage disc with rolling balls or fixed ball heads protruding from its surface. These balls or ball heads contact the soft tissues of the body to massage the abdomen. Some models also incorporate a vibration motor inside the casing, causing the entire device to vibrate at high frequency; these are commonly found in waist belts with fat-burning functions.

[0003] CN202420705669.X discloses an abdominal massager, including a front cover, a housing, and a turntable protruding from the surface of the housing and driven to rotate by a drive mechanism. The turntable has axial protrusions and recessed concave areas spaced apart on its circumference. A shaft hole is formed in the center of the recessed concave area. A first massage head is fitted onto the axial protrusion, and a second massage head is positioned on the shaft hole. The second massage head abuts against the housing, causing it to rotate. The drive mechanism includes a motor, a worm gear box, a battery, and a controller. The battery provides power to the motor and controller, and the controller controls the motor's operation. After the motor is speed-changed by the worm gear box, the output shaft of the worm gear box drives the turntable to rotate. In this structure, two sets of massage heads are arranged on the turntable. The second massage head rotates along with the turntable and also rotates on its own axis, generating different motion trajectories, thus expanding the massage area and increasing efficiency. However, due to the limited rotation range of the massage turntable, the rotation of the second massage head is often not noticeable.

[0004] How to improve the shortcomings of this type of abdominal massage device is the subject of this invention. Summary of the Invention:

[0005] The purpose of this invention is to design a vibrating abdominal massager with massage contacts added to the periphery of the massage disc.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A vibrating abdominal massager includes a front cover, a housing, and a massage disc protruding from the surface of the housing. The massage disc is driven to rotate by a drive mechanism installed inside the housing. The feature is that an acupressure head higher than the surface of the massage disc is provided on the housing outside the massage disc. The height of the acupressure head can be compressed, and a vibration motor is provided inside the acupressure head. The vibration motor and the drive mechanism are both controlled by an electronic control board inside the housing.

[0008] The finger pressure head includes an elastic sleeve and a vibration box. The vibration box, which is equipped with a vibration motor, is embedded in the top of the elastic sleeve. The flange edge at the bottom of the elastic sleeve is clamped and locked to the inner surface of the housing by a pressure ring.

[0009] The elastic sleeve is a corrugated tube or a soft rubber sleeve.

[0010] The acupressure heads are a pair, distributed on the shells on both sides of the massage disc.

[0011] In a preferred embodiment, the massage disc includes an inner disc and an outer disc, both of which have massage heads protruding from their circumferential surfaces; the inner disc is driven to rotate by a central gear, and the outer disc is driven to rotate by an internal gear ring; the drive mechanism includes a dual-output shaft motor and worm gears meshing with worms at the two output shaft ends, and the double gears of the two worm gears mesh with the central gear and the internal gear ring respectively, driving the inner disc and the outer disc to rotate in opposite directions.

[0012] Furthermore, the motor and the two worm gears are constrained between the upper and lower supports, which are locked together on the housing. A central shaft is formed in the middle of the upper support, and the central gear is mounted on the central shaft and is rotatably positioned by a cover locked to the upper support. The cover also positions the double gear shaft of the two worm gears. The inner turntable is locked to the central gear, and the outer turntable is locked to the inner gear ring, which is rotatably positioned on the upper surface of the cover.

[0013] The pressure cap is formed with a collar facing upwards. Screw seats are evenly distributed on the inner side of the collar, and ball pits are evenly distributed on the outer side. The internal gear ring has a round hole that mates with the collar and an annular groove corresponding to the ball pits. The internal gear ring is fitted onto the collar through the round hole. Rolling balls are placed in the ball pits and can abut against one side of the annular groove to form rolling support. The pressure cap is locked with a flanged screw on the screw seat. The flange blocks the upper edge of the internal gear ring and restricts the axial displacement of the internal gear ring.

[0014] The pressure cap is also fixed with an electrode ring having at least two electrodes inside the collar. The bottom of the inner turntable is locked with a photoelectric plate. The photoelectric plate has electrodes corresponding to the electrode rings arranged downwards and supplies power to the photoelectric plate. The photoelectric plate has at least one infrared light-emitting tube mounted on it.

[0015] The inner turntable also has a drug cavity formed in the center and is equipped with a hollow cover.

[0016] The massage heads on both the inner and outer rotating discs are hemispherical heads. The inner rotating disc has two to three hemispherical heads evenly distributed, while the outer rotating disc has three to six groups evenly distributed, each group consisting of three hemispherical heads, one large in the middle and one small on both sides.

[0017] This invention adds a vibrating acupressure head to the outside of the massage disc. It can not only contact the surface of the human body with adaptive pressure, but also generate high-frequency vibration with the help of the built-in vibration motor to enhance the acupressure effect, thus overcoming the shortcomings of the traditional simple rotation and abdominal kneading and enriching the massage experience. In particular, the acupressure head is designed to be highly compressible, which is unique in concept, simple in structure and has the added feature of contact vibration. Attached image description:

[0032] Reference Figures 1 to 4The abdominal massager with vibrating contact points includes a front cover 1, a housing 2, and a massage disc 3 protruding from the surface of the housing 2. The massage disc 3 is driven to rotate by a drive mechanism 4 installed inside the housing 2. Acupressure heads 5 are provided on the housing 2 outside the massage disc 3, generally two or more symmetrically distributed on the left and right sides or top and bottom sides of the massage disc 3. The former is particularly suitable for abdominal massagers with a single massage disc 3, as is the case in this example; the latter is suitable for abdominal massagers with two massage discs 3. Depending on the actual design and the size of the massage disc 3, three or more acupressure heads 5 can also be distributed symmetrically on the housing 2. For example, with three, one can be symmetrically placed on each side of a single massage disc 3 structure, and another can be placed in the upper or lower center; with four acupressure heads 5, one can be placed on each side and top and bottom. In other words, the design can place acupressure heads 5 at any position on the outer shell 2 of the massage disc, with symmetry for aesthetic purposes.

[0033] The acupressure head 5 is higher than the surface of the massage disc 3 and its height can be compressed. A vibration motor 51 is installed inside the acupressure head 5. Both the vibration motor 51 and the drive mechanism 4 are controlled by an electronic control board 6 inside the housing 2. The electronic control board 6 has control buttons 61 protruding from the surface of the housing 2, preferably located on the top side for easy operation. A battery 62 is also installed inside the housing 2, which supplies power to the motor 41 in the drive mechanism 4, the vibration motor 51 in the acupressure head, and the photoelectric plate 71 via the electronic control board 6, and controls functions such as switching between fast and slow motion.

[0034] More specifically, the acupressure head 5 includes a vibration motor 51, a vibration box 52, and an elastic sleeve 53. The vibration box 52, which houses the vibration motor 51, is embedded in the top of the elastic sleeve 53. The flange at the bottom of the elastic sleeve 53 is clamped and locked to the inner surface of the housing 2 by a pressure ring 54. The elastic sleeve 53 is a bellows or a soft rubber sleeve; in this example, it is a soft rubber sleeve, such as a rubber sleeve or a latex sleeve. To increase the resistance, a spring can also be added to the bellows or soft rubber sleeve, thereby increasing the resistance without affecting the compressibility.

[0035] As a preferred embodiment, the massage disc 3 includes an inner disc 31 and an outer disc 32, both of which have massage heads 33 protruding from their circumferential surfaces. The massage heads 33 on both the inner and outer discs 31 are hemispherical heads, and can be combined as follows: the inner disc 31 has two to three hemispherical heads evenly distributed, while the outer disc 32 has three to six groups evenly distributed, each group consisting of three hemispherical heads, one large in the middle and one small on the sides. Because the outer disc 32 has a longer circumference, more massage heads 33 can be provided, and combinations of sizes can be used, with a smoother curve to avoid abrupt changes; a wave-like design can also be used instead of hemispherical head groups. The massage heads 33 on the inner disc 31 can be positioned higher. This is only one preferred combination; for more detailed design, the massage heads 33 can also be designed as rolling ball bearings or rotatable hemispherical heads, allowing the massage heads 33 to rotate.

[0036] The massage disc 3 rotates in opposite directions, with the inner disc 31 driven by the central gear 45 and the outer disc 32 driven by the internal gear ring 46, creating a kneading sensation. The drive mechanism 4 includes a dual-shaft motor 41 and worm gears 43 meshing with the worms 42 at the two shaft ends. The double gears 44 of the two worm gears 43 mesh with the central gear 45 and the internal gear ring 46 respectively, driving the inner disc 31 and outer disc 32 to rotate in opposite directions. Using a dual-shaft motor 41 allows for a more rational spatial layout and more flexible design. To save costs, the two worm gears 43 and the double gears 44 can use the same specification plastic parts, or different sizes of worm gears or double gears can be used to adjust the speed ratios of the inner disc 31 and outer disc 32.

[0037] The structure of the drive mechanism 4 is such that the motor 41 and the two worm gears 43 are constrained between the upper bracket 47 and the lower bracket 48, and the upper bracket 47 and the lower bracket 48 are locked together on the housing 2; the upper bracket 47 also has a central shaft position 471 formed in the middle, the central gear 45 is mounted on the central shaft position 471, and is rotatably positioned by a cover 49 locked on the upper bracket 47. The cover 49 also positions the double gear 44 shaft of the two worm gears 43 to form a transmission chain; the inner turntable 31 is locked on the central gear 45, and the outer turntable 32 is locked on the inner gear ring 46. The inner gear ring 46 is rotatably positioned on the upper surface of the cover 49, and the cover 49 plays the role of connecting the upper and lower parts.

[0038] More specifically, the pressure cap 49 has an upward-facing collar 491. Screw seats 492 are evenly distributed on the inner side of the collar 491, and bead recesses 493 are evenly distributed on the outer side. The internal gear ring 46 has a circular hole 461 that mates with the collar 491 and an annular groove 462 corresponding to the bead recesses 493. The internal gear ring 46 is fitted onto the collar 491 via the circular hole 461, forming a rotational fit. Rolling balls 494 are placed in the bead recesses 493 of the pressure cap, and the rolling balls 494 abut against one side of the annular groove 462 of the internal gear ring, forming rolling support. Alternatively, standard bearings can be used. The pressure cap 49 has a flanged screw 495 locked onto the screw seat 492. The flange blocks the upper edge of the internal gear ring 46, constraining the axial displacement of the internal gear ring 46, simplifying the design of the rotatable positioning structure of the internal gear ring 46, and also simplifying assembly.

[0039] Furthermore, the pressure cap 49 is fixed with an electrode ring 7 having at least two electrodes inside the collar 491. A photoelectric plate 71 is locked at the bottom of the inner turntable 31. The photoelectric plate 71 has corresponding electrodes 72 positioned downwards to power the photoelectric plate 71. The photoelectric plate 71 has at least one infrared light-emitting tube mounted on it. Infrared light passes through the massage turntable 3 and irradiates the human body, forming phototherapy and enhancing the sensory experience, providing a warm, non-cold sensation. A drug cavity 311 is also formed in the center of the inner turntable 31 and is equipped with a perforated cover 312. If necessary, an electric heating element can be added to the drug cavity 311 to heat and fumigate the drug, accelerating the release of active ingredients.
