Description

Field of the invention

[0001] The invention relates to the technical field of massage devices, in particular a gear-driven massage device. State of the art

[0002] As is well known, massagers are a new generation of health devices developed based on physics, bionics, bioelectricity, Chinese medicine, and many years of clinical practice. In daily life, household appliances that use mechanical vibration to stimulate localized parts of the human body use at least one independent soft massage head to relax muscles, soothe nerves, promote blood circulation, strengthen cell metabolism, and increase skin elasticity. They can relieve fatigue, significantly reduce various chronic pains, acute pain, and muscle soreness, relax the body, reduce stress, and reduce skin wrinkles, among other things.

[0003] Currently, most existing massagers only have a single vibration massage function. Structurally, vibration massage is realized by the internal vibration motor, and the massage can only affect one point. You can't massage multiple areas simultaneously. When using the massager, it's difficult to find the right massage point on the human body. In addition, it takes longer to relax the entire body, resulting in low massage efficiency. Object of the invention

[0004] Due to the technical deficiencies in the prior art, the object of the invention is to provide a gear-driven massage device.

[0005] To achieve the above object, the technical solution of the invention is as follows: A gear-driven massage device comprising a housing and a soft cover enclosing the housing, the soft cover forming outwardly projecting massage balls. A mounting plate is provided inside the housing, with at least one main wheel arranged on the mounting plate. A movement space is formed between the mounting plate and the inner wall of the housing. Massage rods are provided in the movement space. The housing is provided with through-holes, the number of which corresponds to the number of massage rods. The heads of the massage rods extend from the through-holes and engage the massage balls. The massage rods are each provided with an elongated hole. The main wheel has an eccentric rod, the eccentric rod being inserted into the elongated hole. A main circuit board and a drive motor electrically connected to the main circuit board are provided in the housing.wherein the rotary shaft of the drive motor is fixedly connected to an output gear, wherein the output gear is connected to the main gear via a first driven gear and the main gear rotates, whereby the massage rods move back and forth in the movement space to massage the human body.

[0006] Preferably, when the number of massage rods is two or more than two, the number of the main gear corresponds to the number of massage rods, the main gears being connected via second driven gears.

[0007] Preferably, the slot runs in a horizontal or vertical direction.

[0008] Preferably, if the elongated hole extends in the horizontal direction, the housing is provided with a limiting hole at each of the through-holes, wherein the shaft of the massage stick is located in the limiting hole, so that the massage stick can only perform back-and-forth tapping movements in one direction.

[0009] Preferably, when the elongated hole extends in the vertical direction, a part of the massage stick is hingedly attached between the mounting plate and the housing so that the massage stick performs reciprocating pivoting movements within a fixed range.

[0010] Preferably, the end of the massage stick is provided with a fixing head, wherein the diameter of the fixing head is larger than the diameter of the massage stick, wherein the fixing head has a cylindrical, spherical, trapezoidal or special shape or a combination thereof, wherein the number of fixing heads is at least one, wherein the fixing head is press-fitted inside the massage ball so that the fixing head does not detach from the massage ball during the massage process, thereby better transmitting the force to the massage ball, reducing the force loss and improving the massage experience.

[0011] Preferably, the soft cover forms a deformation portion around the massage balls, wherein the thickness of the deformation portion is smaller than the thickness of the main body of the soft cover, and wherein the deformation portion is water-wave-shaped, wavy or wrinkled to increase the elongation and elasticity of the massage balls.

[0012] Preferably, each massage stick is asymmetrical on one side or symmetrical on both sides.

[0013] Preferably, at least one vibration motor is provided in the housing, wherein the vibration motor is located at the edge of the housing, wherein the vibration motor is electrically connected to the main board, wherein a battery and a push button on the main board are provided in the housing, wherein the battery is electrically connected to the main board, and wherein the push section of the push button is in contact with the inner wall of the soft shell.

[0014] Preferably, the battery is a rechargeable battery, wherein the housing is provided with a charging contact, and wherein the soft cover is provided with a feed-through opening at the location of the charging contact.

[0015] In the above-mentioned solution, the invention uses the drive motor to drive the gears. The gears drive the encentric rods, creating rapid and continuous tapping or oscillating movements that can quickly relieve muscle fatigue. Furthermore, the invention features multi-point massage and can massage multiple body parts simultaneously, expanding the massage area. It is easier for users to target multiple massage points at once. The transmission connection between the gears can control the force distribution, ensuring the uniformity and continuity of the massage movements, thus avoiding local overstimulation. Therefore, this invention not only increases the efficiency and range of the massage but also the comfort of the massage.

[0016] The invention particularly relates to a gear-driven massage device comprising a housing (1) and a soft cover (2) enclosing the housing (1), wherein the soft cover (2) forms outwardly projecting massage balls (3), wherein a fastening plate (4) is provided inside the housing (1), wherein at least one main wheel (5) is arranged on the fastening plate (4), wherein a movement space is formed between the fastening plate (4) and the inner wall of the housing (1), wherein massage rods (6) are provided in the movement space, wherein the housing (1) is provided with through-holes (7), the number of which corresponds to the number of massage rods (6), wherein the heads of the massage rods (6) extend from the through-holes (7) and engage in the massage balls (3), wherein the massage rods (6) are each provided with an elongated hole (8), wherein the main wheel (5) has an eccentric rod (9), wherein the eccentric rod (9) engages in the elongated hole (8) is used,The housing (1) contains a main board (10) and a drive motor (11) electrically connected to the main board (10), the rotary shaft of the drive motor (11) being fixedly connected to an output gear (12). The invention allows the user to target multiple massage points at once, thereby increasing not only the efficiency and scope of the massage, but also the comfort of the massage.

Description of the preferred embodiments

[0017] To further clarify the purpose, technical solutions, and advantages of the present invention, the invention will be described in more detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein serve only to illustrate the present invention and are not intended to limit the present invention.

[0018] As in Fig. 1 to 6, this embodiment provides a gear-driven massager comprising a housing 1 and a soft shell 2 enclosing the housing 1. The soft shell 2 forms outwardly projecting massage balls 3. A mounting plate 4 is provided inside the housing 1. At least one main wheel 5 is arranged on the mounting plate 4. A movement space is formed between the mounting plate 4 and the inner wall of the housing 1. Massage rods 6 are provided in the movement space. The housing 1 is provided with through-holes 7, the number of which corresponds to the number of massage rods 6. The heads of the massage rods 6 extend from the through-holes 7 and engage with the massage balls 3. The massage rods 6 are each provided with an elongated hole 8. The main wheel 5 has an eccentric rod 9. The eccentric rod 9 is inserted into the elongated hole 8.The housing 1 contains a main board 10 and a drive motor 11 electrically connected to the main board 10. The rotating shaft of the drive motor 11 is fixedly connected to an output gear 12. The output gear 12 is connected to the main gear 5 via a first driven gear 13. When the drive motor 11 is turned on, the driven gear 12 rotates the first driven gear 13 synchronously, thereby transmitting the rotating power to the main gear 5. After the main gear 5 is rotated, the eccentric rod 9 arranged eccentrically on the main gear 5 moves along a circular path. Since the eccentric rod 9 is located in the elongated hole 8, the massage rod 6 is forced to move, such as beating back and forth or swinging left and right. In combination with the deformation of the soft cover 2, the user can place the massager on the skin to massage the human body, thereby expanding the massage position and massage range.

[0019] Furthermore, if the number of massage rods 6 is two or more, the number of main gear 5 corresponds to the number of massage rods 6. The main gears 5 are connected via second output gears 14. In this way, a single drive motor 11 can drive all massage rods 6 to move.

[0020] In addition, this embodiment provides two types of massage movements: a tapping massage and a swing and pressure massage. To realize these two types of massage, separate structural designs are required. Specifically, the elongated hole 8 extends horizontally or vertically. If the elongated hole 8 extends horizontally, the housing 1 is provided with a limiting hole 15 at each of the through-holes 7. The shaft of the massage rod 6 is located in the limiting hole 15, so that the massage rod 6 can only perform reciprocating tapping movements in one direction. If the elongated hole 8 extends vertically, as shown in Fig. 5, a part of the massage stick 6 is hingedly attached between the mounting plate 4 and the housing 1, so that the massage stick 6 performs back and forth swinging movements within a fixed range.

[0021] Furthermore, to enhance the tapping effect, the end of the massage rod 6 in this embodiment is provided with a fixing head 16. The diameter of the fixing head 16 is larger than the diameter of the massage rod 6. The fixing head 16 has a cylindrical, spherical, trapezoidal, or special shape, or a combination thereof. The number of fixing heads 16 is at least one. The fixing head 16 is press-fitted inside the massage ball 3, so that the fixing head 16 will not detach from the massage ball 3 during the massage process. It can better transmit the force to the massage ball 3, reduce force loss, and enhance the massage experience.

[0022] Furthermore, to enable better deformation of the soft cover 2 on the massage balls 3, the soft cover 2 in this embodiment forms a deformation section 17 around the massage balls 3. The thickness of the deformation section 17 is smaller than the thickness of the main body of the soft cover 2. The deformation section 17 is water-wave-shaped, wavy, or wrinkled to increase the elongation and elasticity of the massage balls.

[0023] In addition, the design of each massage stick 6 can be changed. Each massage stick 6 can be unilaterally asymmetrical or bilaterally symmetrical. Bilateral symmetry means that the upper and lower ends each have a head, while unilateral asymmetry, as in Fig. 6 means that only one end has a head.

[0024] Furthermore, to provide the user with multiple massage options, this embodiment provides at least one vibration motor 18 in the housing 1. The vibration motor 18 is located on the edge of the housing 1. The vibration motor 18 is electrically connected to the main board 10. Therefore, the user can select a tapping massage or a vibration massage as needed.

[0025] Furthermore, the housing 1 of this embodiment includes a battery 19 and a push button 10 provided on the main board 10 for the internal power system. The battery 19 is electrically connected to the main board 20. The push portion of the push button 20 is in contact with the inner wall of the soft case 2. The battery 19 is a rechargeable battery. The housing 1 is provided with a charging contact 21. The soft case 2 is provided with a through hole at the location of the charging contact 21. The massager can be held by hand to perform the massage. Combined with the charging function, it can be used repeatedly. The charging contact 21 can ensure a waterproof function.

[0026] The above-mentioned embodiments are merely preferred embodiments of the present invention, which do not limit the scope of the present invention. Any equivalent structure or equivalent process conversion made using the description and drawings of the present invention, or used directly or indirectly in other related fields, are all included within the scope of the present invention.
