Description

Technical Field

[0001] The invention relates to the field of massagers, and in particular to a massager with a flexible swing structure and a control method thereof. Background Art

[0002] The massager mainly simulates the human body's hand movements through predetermined mechanical movements, and then massages the predetermined meridians or skin to achieve a soothing effect.

[0003] However, the existing massagers are generally rigidly struck, that is, the driving mechanism is directly connected to the massage head using a cam, thereby directly striking the massage area, thereby achieving a massage effect.

[0004] For example, in the existing fascia gun product, Chinese patent CN202322093925.2, the massage head and the driving mechanism are directly connected to achieve the predetermined action.

[0005] Of course, there are also massagers that use flexible massage, such as Chinese patent CN202322685712.9, which achieves the effect of flexible massage by setting an elastic base.

[0006] However, both of the above structures cannot achieve the effect of flexible tapping massage. In a better massage technique, the hand needs to tap with the hand joint as a fulcrum, but the arm as a whole cannot move, so as to achieve a flexible tapping massage technique, thereby effectively relieving the meridians. Summary of the invention

[0007] The main purpose of the present invention is to propose a massager with a flexible swing structure and a control method thereof, aiming to improve the existing massager structure, thereby simulating the technique of flexible massage, and then simulating the massage effect of the human body with the hand joints as the fulcrum.

[0008] To achieve the above object, the present invention provides a massager with a flexible swing structure, comprising:

[0009] A rotating device, wherein the rotating device is provided with a driving shaft, wherein the driving shaft is provided with a driving portion with an eccentric axis, and the driving portion can rotate along the periphery of the axis;

[0010] A flexible arm, wherein the flexible arm is provided with a limiting structure, wherein the limiting structure is used to limit the end of the flexible arm from swinging in a single direction, and the lower end of the flexible arm is connected to the driving part;

[0011] A covering layer, wherein the covering layer covers the flexible arm, and the covering portion is located at an end of the flexible arm and is provided with a massage head;

[0012] When the driving part rotates, the flexible arm can be driven to swing, and the massage head is forced to swing in a single direction.

[0013] In the actual design, the flexible arm can be swung in a single direction through the limiting structure of the flexible arm, thereby converting the rotation stroke of the driving part into a swing stroke in a single direction, so that the massage head can swing back and forth with the rear end of the flexible arm as the fulcrum, thereby achieving the effect of flexible massage and kneading;

[0014] It has the following advantages:

[0015] 1. By using a simple flexible arm in a single direction as a limiting structure, the rotation stroke is converted into a swing in a single direction, thereby realizing the flexible tapping of the massage head;

[0016] 2. Through the setting of the flexible arm, flexible percussion massage is realized, which effectively simulates the massage of the human hand, while avoiding the strain of meridians caused by rigid percussion, improving the experience of mechanical massage. At the same time, the structure is simple and does not require special cam structures;

[0017] 3. Through the setting of flexible arms (reducing abnormal noise caused by mechanical engagement or impact), the structure has lower noise, more stable transmission, and improved user experience.

[0018] A massager control method, characterized in that it includes the above-mentioned massager with a flexible swing structure, and the working steps include:

[0019] S1: When the rotating device rotates, the driving shaft rotates with the smooth section of the flexible arm as the fulcrum;

[0020] S2: When the driving part is located in the swinging interval of the plane wall, the rotational potential energy of the driving part is converted into the swinging potential energy of the flexible arm, and the upper section of the flexible arm swings with the smooth section as a fulcrum, and the first deformation groove and the second deformation groove switch between the mutually squeezed position or the mutually distant position;

[0021] S3: When the driving part is located in the swinging range of the circular wall and the flexible arm is in the smooth section, the driving part rotates to a position where it cannot rotate or is restricted, and its rotational potential energy is absorbed by the deformation channel and squeezes the upper end of the transitionally swinging flexible arm to swing.

[0022] The control method also includes a connection process, that is, when the driving part rotates to the circular wall, the first deformation groove and the second deformation groove are deformed according to the pressure value, thereby avoiding the generation of torsion force, thereby realizing the conversion of the rotation stroke into a swing stroke in a single direction.

[0037] like Figures 1 to 4As shown, a massager with a flexible swing structure and a control method thereof include:

[0038] A rotating device 1, wherein the rotating device 1 is provided with a driving shaft 10, wherein the driving shaft 10 is provided with a driving portion 5 with an eccentric axis, and the driving portion 5 can rotate along the periphery of the axis;

[0039] A flexible arm 2, wherein the flexible arm 2 is provided with a limiting structure, wherein the limiting structure is used to limit the end of the flexible arm 2 from swinging in a single direction, and the lower end of the flexible arm 2 is connected to the driving part 5;

[0040] A covering layer 3, wherein the covering layer 3 covers the flexible arm 2, and a massage head 30 is provided at an end of the covering portion of the flexible arm 2;

[0041] When the driving part 5 rotates, the flexible arm 2 can be driven to swing, and the massage head 30 can be forced to swing in a single direction.

[0042] In the actual design, the flexible arm 2 can be swung in a single direction through the limiting structure of the flexible arm 2, thereby converting the rotation stroke of the driving part 5 into a swing stroke in a single direction, so that the massage head 30 can swing back and forth with the rear end of the flexible arm 2 as the fulcrum, thereby achieving the effect of flexible massage and kneading;

[0043] It has the following advantages:

[0044] 1. By using a simple single-direction flexible arm 2 as a limiting structure, the rotation stroke is converted into a single-direction swing, thereby realizing the flexible tapping of the massage head 30;

[0045] 2. Through the setting of the flexible arm 2, a flexible percussion massage is realized, which effectively simulates the massage of the human hand, while avoiding the strain of meridians caused by rigid percussion, improving the experience of mechanical massage, and the structure is simple, and no special cam structure is required;

[0046] 3. Through the setting of the flexible arm 2 (reducing abnormal noise caused by mechanical engagement or impact), the noise of the structure is smaller, the transmission is more stable, and the user experience is improved.

[0047] Specifically, the flexible arm 2 is in the shape of an elongated strip and a non-circular structure, thereby achieving swing in a single direction.

[0048] In the embodiment of the present invention, the left and right sides of the flexible arm 2 are circular walls 21, and the upper and lower sides of the flexible arm 2 are plane walls 22, thereby achieving swing in a predetermined direction. Therefore, the flexible arm 2 is also required to have a certain supporting force to prevent the upper end of the flexible arm 2 from rotating under the action of the rotation stroke.

[0049] Specifically, the flexible arm 2 is in a flat structure and has a predetermined support degree, thereby preventing the flexible arm 2 from swinging in a non-flat direction due to the rotation stroke exceeding a predetermined pressure value.

[0050] In the embodiment of the present invention, the limiting structure includes a first deformation groove 201 provided on the lower plane wall 22 of the flexible arm 2, and the driving shaft 10 extends into the first deformation groove 201;

[0051] The limiting structure further includes a second deformation groove 202 provided on the outer peripheral wall of the upper section of the flexible arm 2, a smooth section 203 is provided between the second deformation groove 202 and the first deformation groove 201, and the driving part 5 is provided at the position of the smooth section 203;

[0052] The massage head 30 reciprocates with the smooth section 203 as a fulcrum.

[0053] By disposing the first deformation groove 201, the second deformation groove 202 and the smooth section 203, and coordinating the position of the driving part 5, the rotation stroke is converted into a swing stroke in a single direction.

[0054] Specifically, the first deformation grooves 201 are provided with three groups, and the second deformation grooves 202 are provided with two groups. According to the number of the provided deformation grooves and the depth of the deformation grooves on both sides, the swing amplitude and deformation direction of the massage head 30 are limited.

[0055] For example, if the depth of the rear plane wall 22 is greater than the depth of the front plane wall 22 , the deformation degree of the front side will be greater than the deformation degree of the rear side.

[0056] In the embodiment of the present invention, the cross-sections of the first deformation groove 201 and the second deformation groove 202 are trapezoidal surfaces, and the trapezoidal surfaces are gradually reduced in diameter from the outside to the inside. When the inner side wall of the trapezoidal surface of the corresponding flexible arm 2 is reduced to a predetermined angle, outward pressure is generated, thereby causing the massage head 30 to deform in the direction of the expansion of the deformation groove, thereby achieving reciprocating swing.

[0057] Specifically, the lower section of the flexible arm 2 is provided with a slot 4, the driving part 5 extends into the slot 4, and the slot 4 extends along the length of the flexible arm 2; the upper section of the slot 4 is a deformation channel 40;

[0058] The driving part 5 includes a shaft part 51 integrally extending from the driving part 5 or the shaft part 51 installed on the driving part 5 and an eccentric part 51 obliquely extending from the upper end of the shaft part 51, and a circular limiting part is provided at the upper end of the eccentric part, and the limiting part is located at the position of the smooth section 203, thereby facilitating the matching and installation between the driving part 5 and the slot 4, such as fixing with glue;

[0059] The slot 4 runs through the length direction of the flexible arm 2 , so the upper section of the slot 4 is a deformation channel 40 , which can absorb the kinetic energy of the driving part 5 in a single direction.

[0060] Specifically, a hollow cavity 6 is provided at the upper end of the flexible arm 2, and a vibration motor 61 is provided in the hollow cavity 6. The massage head is in a hammer-shaped structure, wherein the vibration motor can improve the massage effect, and the contoured structure can make the force more concentrated.

[0061] The rotating device 1 is a rotating motor or a rotating motor matched with a gear box, and the flexible arm 2 is made of rubber material.

[0062] A massager control method includes the above-mentioned massager with a flexible swing structure, and the working steps include:

[0063] S1: When the rotating device 1 rotates, the driving shaft 10 rotates with the smooth section 203 of the flexible arm 2 as a fulcrum;

[0064] S2: When the driving part 5 is located in the swinging range of the plane wall 22, the rotational potential energy of the driving part 5 is converted into the swinging potential energy of the flexible arm 2, and the upper section of the flexible arm 2 swings with the smooth section 203 as a fulcrum, and the first deformation groove 201 and the second deformation groove 202 are switched between mutually squeezed positions or mutually distant positions;

[0065] S3: When the driving part 5 is located in the swinging range of the circular wall 21, and the flexible arm 2 is in the position of the smooth section 203, the driving part 5 rotates to a position where it cannot rotate or is restricted, and its rotational potential energy is absorbed by the deformation channel 40 and squeezes the upper end of the transitionally swinging flexible arm 2 to swing.

[0066] The control method also includes a connection process, that is, when the driving part 5 rotates to the circular wall 21, the first deformation groove 201 and the second deformation groove 202 are deformed according to the pressure value, thereby avoiding the generation of torsion force, thereby realizing the conversion of the rotation stroke into a swing stroke in a single direction.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
