Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of massage machinery, and more specifically, the embodiments of the present application relate to a massager. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the application that are recited in the claims. No description herein is admitted to be prior art by inclusion in this section.

[0003] At present, the clamping arm and the massage part of the massager are fixed by screws or buckles to form a stable C-shaped opening device, and the clamping arm and the massage part are both unable to be adjusted, and cannot meet more requirements of users.

[0004] The main problems are: the massager is large and inconvenient to store, which does not meet the property of wearable devices that are easy to store when worn; moreover, the existing massagers cannot be adapted to different individuals due to the differences in the sizes of the massaged parts. When the size of some massaged parts is small, the massage part is loose to wear, resulting in the massage part being unable to contact the human body and having no massage effect. When the size of some massaged parts is large, the massage part is tight to wear, and long-term clamping can cause a feeling of suffocation, swelling, poor blood flow, etc.

[0005] Therefore, an improved massager is greatly needed to improve the storage performance of the massager and avoid the inconvenience of carrying; and the clamping distance can be adjusted to suit different users. Summary of the invention

[0053] The principles and spirit of the present application will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present application, and are not intended to limit the scope of the present application in any way. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0054] It should be understood herein that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction rather than having any limiting meaning. SUMMARY OF THE INVENTION

[0056] The inventors of the present application have discovered that the clamping arms and massage parts of existing cervical massagers are fixed by screws or buckles to form a stable C-shaped opening, and the clamping arms cannot rotate or extend. It is inconvenient to store and carry, and cannot be adapted due to differences in individual neck sizes. For some users with smaller necks, the massage parts cannot come into contact with the human body and have no massage effect. For some users with larger necks, the massage parts are too tight to be worn, and long-term clamping can easily lead to a feeling of suffocation.

[0057] To this end, in the embodiment of the present application, the two clamping arms 1 are rotatably connected to the connecting seat 2, so that the two clamping arms 1 can be rotated and folded; the massage mechanism 4 is connected to the clamping arm 1 or rotatably connected to the connecting seat 2, so that the massage mechanism 4 can also be rotated and folded, or the massage mechanism 4 can be rotated and folded together with the clamping arm 1; and the two clamping arms 1 are positioned by the positioning mechanism 3 when the two clamping arms 1 are in the unfolded state and the folded state, so as to better fix the massager in the unfolded state or the folded state, and avoid the phenomenon of unstable state during use. In addition, an adjustment mechanism is provided in the massager, and the adjustment mechanism can adjust the clamping distance between the two clamping arms 1. When using, the user can directly pull the two clamping arms 1 to adjust different clamping distances, so that the massager is suitable for different people.

[0058] After introducing the basic principles of the present application, various non-limiting implementation methods of the present application are described in detail below.

[0059] Application Scenario Overview

[0060] The massager of the embodiment of the present application can be a cervical massager, in which the two clamping arms 1 are clamped on the user's neck, and the massage part 41 fits the user's neck; it can also be a waist and abdomen massager, in which the two clamping arms 1 are clamped on the user's waist and abdomen, and the massage part 41 fits the user's waist and abdomen; it can also be a limb massager, in which the two clamping arms 1 are clamped on the user's limbs, and the massage part 41 fits the user's limbs; of course, it can also be a head massager, in which the two clamping arms 1 are clamped on the user's head, and the massage part 41 fits the user's head.

[0061] When the user needs to carry the massager outside, the two clamping arms 1 and the massage mechanism 4 are rotated to form a folded state, so that the massager occupies less space and is convenient to carry; and after being positioned by the positioning mechanism 3, the massager is in a more stable state and will not become scattered during the process of going out.

[0062] When different users use the massager, the users can adjust different clamping distances by simply pulling the two clamping arms 1, which is convenient for users to wear.

[0063] Exemplary Devices

[0064] Combine the following Figure 1 and Figure 2 A massage apparatus according to an exemplary embodiment of the present application will be described.

[0065] like Figure 1 and Figure 2 As shown, the massager of this embodiment may include a connecting seat 2 , a massage mechanism 4 , two clamping arms 1 and two positioning mechanisms 3 .

[0066] The following is a detailed explanation using a neck massager as an example.

[0067] In this embodiment, the two clamping arms 1 are symmetrically arranged. The clamping arm 1 may include a clamping arm body 11 and a rotating shaft 12. The clamping arm body 11 is arranged in an arc shape, and the two clamping arm bodies 11 cooperate to form an arc shape that matches the human neck. Of course, when the clamping arm body 11 is used to clamp the waist, abdomen, limbs, head, etc., correspondingly, the two clamping arm bodies 11 cooperate to form an arc shape that matches the waist, abdomen, limbs, head, etc. of the human body.

[0068] Reference Figure 3-Figure 5As shown, the clamping arm body 11 includes a first cover 111 and a second cover 112, which can be fixedly connected by screws or buckles; the first cover 111 is located on the side away from the user, and the first cover 111 is set to an arc shape that is compatible with the clamping arm body 11; the second cover 112 is located on the side close to the user, and the second cover 112 is also set to an arc shape that is compatible with the clamping arm body 11, and the second cover 112 is connected to the connecting seat 2. The clamping arm body 11 is formed into a hollow structure to reduce the weight of the entire massager and increase the elasticity of the clamping arm 1.

[0069] The side of the clamping arm body 11 away from the massage mechanism 4 is set as an arc surface, that is, the outer side of the first cover body 111 away from the human body is set as an arc surface; and the arc surface protrudes toward the side away from the massage mechanism 4. Figure 4 As shown, the height Y from the top to the bottom of the arc surface is less than or equal to 5 mm, so that the first cover body 111 of the clamping arm 1 has appropriate elasticity and can be elastically deformed and opened, making the human body comfortable to wear.

[0070] Reference Figure 5 As shown, the side of the second cover 112 that contacts the user is configured to be arc-shaped, that is, the second cover 112 is configured as an arc-shaped shell 31 as a whole, so that the contact between the second cover 112 and the user is softer, thereby improving the user experience of the user.

[0071] Reference Figure 5 As shown, a boss 16 is provided at one end of the second cover 112 connected to the connection seat 2, the boss 16 protrudes toward the massage mechanism 4, and a surface of the boss 16 connected to the connection seat 2 is set as a plane, and the boss 16 can avoid mutual interference between the clamping arm 1 and the connection seat 2 when the clamping arm 1 rotates. Of course, the boss 16 may not be provided, and in order to avoid interference, the connection seat 2 may be set as an arc shape that matches the clamping arm 1.

[0072] A first groove 13 and a second groove 14 are provided on one side of the boss 16 connected to the connecting seat 2, and the second groove 14 is provided in a circular shape, that is, the second groove 14 is provided in a circular blind hole or a through hole; the first groove 13 is provided in a long strip shape, and the extension direction of the first groove 13 is consistent with the adjustment direction of the clamping arm 1 in the unfolded state, that is, the extension direction of the first groove 13 is consistent with the direction of the clamping spacing X; part of the first groove 13 and the second groove 14 are located on the same circle centered on the rotating shaft 12 of the clamping arm 1, and the first groove 13 and the second groove 14 are correspondingly located on two mutually perpendicular diameters of the circle.

[0073] In addition, in other embodiments of the present application, two first grooves 13 may be provided so that the clamping arm 1 can be folded in two directions, which are opposite to each other; an arc-shaped running groove may be provided between the first groove 13 and the second groove 14, that is, the running groove connects the first groove 13 and the second groove 14, and the depth of the running groove is less than the depth of the first groove 13 and the second groove 14; the running groove may be a quarter of an arc. When the massager changes from a folded state to an unfolded state or from an unfolded state to a folded state, the positioning block 33 may slide in the running groove, and the running groove provides guidance for the movement of the positioning block 33, so as to avoid the positioning block 33 from being misaligned when the state changes, and the purpose of the state change cannot be achieved.

[0074] Reference Figure 5 As shown, a rotating shaft 12 is arranged on the boss 16, and the rotating shaft 12 is arranged as a hollow shaft; and a first snap ring 15 is arranged at one end of the rotating shaft 12 away from the clamping arm 1, and the first snap ring 15 has an inner ring surface and an outer ring surface, and the inner ring surface of the first snap ring 15 is coplanar with the inner wall of the rotating shaft 12, and the edge of the outer ring surface of the first snap ring 15 away from the clamping arm 1 is provided with an inclined chamfer. The rotating shaft 12 includes four arc-shaped shaft walls arranged at intervals, and the four arc-shaped shaft walls and the intervals between them surround the cylindrical rotating shaft 12. The first snap ring 15 includes four first sub-snap rings arranged at intervals, and the four sub-first sub-snap rings and the intervals between them surround the annular first snap ring 15. The first sub-snap rings are fixed one by one to the end of the arc-shaped shaft wall away from the clamping arm 1. Such a setting is to make the radial size of the first snap ring 15 adjustable, so as to facilitate the installation of the rotating shaft 12 into the connecting seat 2 through the second through hole 221.

[0075] Please continue to refer to Figure 1 and Figure 2 As shown, the connecting seat 2 may include a connecting seat body 21 and a connecting seat cover body 22, wherein the connecting seat cover body 22 covers the side of the connecting seat body 21 close to the clamping arm 1, that is, the connecting seat body 21 is located on the side close to the massage mechanism 4, and the connecting seat cover body 22 is located on the side close to the clamping arm 1.

[0076] Two first through holes 211 are provided on the connecting seat body 21, and the two connecting shafts 412 pass through the two first through holes 211 one by one; the first through hole 211 is set to be an elongated strip, for example, the first through hole 211 is a first waisted hole, and the extension direction of the first through hole 211 is consistent with the adjustment direction (the direction of the clamping spacing) of the clamping arm 1 when it is in the unfolded state, that is, the extension direction of the first through hole 211 is consistent with the extension direction of the first groove 13, providing sufficient moving space for the adjustment of the massager.

[0077] Two second through holes 221 are arranged on the connecting seat cover 22, and the two rotating shafts 12 pass through the two second through holes 221 one by one; the second through holes 221 are arranged in a long strip shape, for example, the second through hole 221 is a second oval hole, and the extension direction of the second through hole 221 is consistent with the adjustment direction (the direction of the clamping spacing) of the clamping arm 1 when it is in the unfolded state, that is, the extension direction of the second through hole 221, the extension direction of the first through hole 211 and the extension direction of the first groove 13 are all consistent, providing sufficient moving space for the adjustment of the massager. The width of the second through hole 221 is substantially equal to the diameter of the rotating shaft 12, and the width of the second through hole 221 is smaller than the outer diameter of the first clamping ring 15, so that after the rotating shaft 12 is installed in the second through hole 221, it can be engaged with the second through hole 221 in the width direction to prevent the rotating shaft 12 from shaking in the width direction; and the first clamping ring 15 can prevent the rotating shaft 12 from falling out of the second through hole 221.

[0078] In addition, the height of the rotating shaft 12 is substantially equal to the depth of the second through hole 221 , that is, the height of the rotating shaft 12 is substantially equal to the thickness of the connecting seat cover 22 , so that the first clamping ring 15 and the boss 16 can enable a tighter connection between the clamping arm body 11 and the connecting seat 2 .

[0079] Two positioning grooves are provided between the two second through holes 221 of the connecting seat cover body 22, and a positioning mechanism 3 is installed in the positioning groove. The positioning mechanism 3 may include a shell 31, a positioning elastic member 32 and a positioning block 33; the shell 31 is installed in the positioning groove, and an opening is provided at one end of the shell 31, and the opening is arranged in a gradually narrowing shape to prevent the positioning block 33 from falling out of the opening. The opening is located on the side close to the clamping arm 1. One end of the positioning elastic member 32 is fixed to the bottom wall of the shell 31, and the bottom wall is arranged opposite to the opening. The positioning block 33 is connected to the other end opposite to the positioning elastic member 32, and the positioning block 33 is arranged as a sphere, so that the side of the positioning block 33 away from the positioning elastic member 32 is a spherical surface, and the spherical part protrudes from the opening and the positioning groove 212; the positioning block 33 is located in the first groove 13 when in the unfolded state, and the positioning block 33 is located in the second groove 14 when in the folded state.

[0080] Of course, in other embodiments of the present application, the shell 31 may not be provided, and the positioning elastic member 32 may be directly fixed in the positioning groove; the positioning block 33 does not have to be provided as a sphere. For example, the positioning block 33 may be provided as a spherical structure, and the plane of the spherical segment is fixedly connected to the positioning elastic member 32, and part of the spherical surface of the spherical segment protrudes from the positioning groove; the positioning block 33 may also be provided as an ellipsoid, a semi-ellipsoid, and the like.

[0081] When the massager is in the unfolded state and needs to be folded, the user holds the two clamping arms 1 in each hand and rotates the two clamping arms 1 toward the user or away from the user. The positioning block 33 is squeezed by the groove wall of the first groove 13 and retracts into the shell 31. The positioning elastic member 32 is squeezed and shortened to generate elastic force until the positioning block 33 completely leaves the first groove 13. The two clamping arms 1 are continuously rotated. When the positioning block 33 reaches the second groove 14, the positioning block 33 is ejected and inserted into the second groove 14 under the elastic force of the positioning elastic member 32, so that the massager can be folded as shown in the figure. Figure 6 Shown in folded state.

[0082] When the massager is in the folded state and needs to be unfolded, the user holds the two clamping arms 1 in each hand, and rotates the two clamping arms 1 toward the user or away from the user. The positioning block 33 is squeezed by the groove wall of the second groove 14 and retracts into the shell 31. The positioning elastic member 32 is squeezed and shortened, generating elastic force until the positioning block 33 completely leaves the second groove 14. The two clamping arms 1 are continuously rotated. When the positioning block 33 reaches the first groove 13, the positioning block 33 is ejected and inserted into the first groove 13 under the elastic force of the positioning elastic member 32, so that the massager is unfolded as shown in the figure. Figure 7 The unfolded state is shown in the figure, and the arrow in the figure shows the rotation direction.

[0083] Please continue to refer to Figure 1 and Figure 2 As shown, the massage mechanism 4 may include two massage parts 41 , the two massage parts 41 are symmetrically arranged, and the two massage parts 41 are correspondingly connected to the two clamping arms 1 .

[0084] Specifically, the massage part 41 may include an electrode seat 411 and a connecting shaft 412; the two electrode seats 411 cooperate to form an arc that is adapted to the neck. Of course, when the massage part 41 is used to massage the waist, abdomen, limbs, head, etc., correspondingly, the two electrode seats 411 cooperate to form an arc that is adapted to the waist, abdomen, limbs, head, etc. of the human body.

[0085] An electrode sheet 413 and a heating component are provided on the electrode holder 411. The electrode sheet 413 has heating and discharging functions. The frequency and magnitude of the electric current hitting the human body are controlled by a program to simulate various massage techniques of traditional Chinese medicine, so that the massage part 41 can perform low-frequency pulse, magnetic therapy, infrared heat moxibustion, and pillow traction on the neck.

[0086] A protrusion 414 is provided on one side of the electrode holder 411 close to the connection holder 2. The protrusion 414 protrudes toward one side of the connection holder 2. The side of the protrusion 414 close to the connection holder 2 is set as a plane. One end of the connecting shaft 412 is connected to the plane of the protrusion 414. A second clamping ring 415 is provided in the middle of the connecting shaft 412. The second clamping ring 415 and the plane on the protrusion 414 clamp the connecting shaft 412 on the connection holder body 21, that is, the distance between the side of the second clamping ring 415 close to the protrusion 414 and the plane on the protrusion 414 is substantially equal to the thickness of the bottom plate of the connection holder body 21, and the distance between the side of the second clamping ring 415 close to the protrusion 414 and the plane on the protrusion 414 is substantially equal to the depth of the first groove 13.

[0087] The other end of the connecting shaft 412 is inserted into the hollow shaft of the rotating shaft 12, and the rotating shaft 12 can drive the connecting shaft 412 to rotate. Specifically, a keyway is provided on the hollow inner wall of the rotating shaft 12, and a fixed key that matches the keyway is provided on the outer wall of the connecting shaft 412. After the connecting shaft 412 is inserted into the rotating shaft 12, the fixed key is also inserted into the keyway, so that the rotating shaft 12 can drive the connecting shaft 412 to rotate. In addition, conversely, the fixed key can be provided on the rotating shaft 12, and the keyway can be provided on the connecting shaft 412.

[0088] Of course, in other embodiments of the present application, the cross-section of the connecting shaft 412 can be set to a non-circular shape, for example, an ellipse, a polygon, etc.; since the rotating shaft 12 is set to a hollow shaft, the cross-section of the rotating shaft 12 will have two inner and outer edge lines, the outer edge line is formed by the outer wall of the rotating shaft 12, and the inner edge line is formed by the inner wall of the rotating shaft 12; the inner wall of the rotating shaft 12 cooperates with the connecting shaft 412, and the inner edge line of the cross-section of the rotating shaft 12 can be set to a non-circular shape that cooperates with the connecting shaft 412, that is, the cross-section of the inner wall of the rotating shaft 12 is set to a non-circular shape that cooperates with the connecting shaft 412, corresponding to, for example, an ellipse, a polygon, etc.

[0089] The connecting shaft 412 can also be set as a hollow shaft. After the connecting shaft 412 is inserted into the rotating shaft 12, a channel is formed. The wires connecting the electrode sheet 413 and the heating component can pass through the channel formed by the connecting shaft 412 and the rotating shaft 12, which is convenient for the routing of the electrical wiring harness; and because the wiring harness is in the channel, it can be protected from being clamped off or pulled off when the clamping arm 1 is opening or rotating.

[0090] The second retaining ring 415 has an inner ring surface and an outer ring surface. The inner ring surface of the second retaining ring 415 is coplanar with the inner wall of the connecting shaft 412, and the edge of the outer ring surface of the second retaining ring 415 away from the electrode seat 411 is provided with an inclined chamfer. The connecting shaft 412 includes four arc-shaped shaft walls arranged at intervals, and the four arc-shaped shaft walls and the intervals between them surround a cylindrical connecting shaft 412. The second retaining ring 415 includes four second sub-retaining rings arranged at intervals, and the four sub-second sub-retaining rings and the intervals between them surround a circular second retaining ring 415. The second sub-retaining rings are fixed in the middle of the arc-shaped shaft wall in a one-to-one correspondence. This arrangement is to make the radial dimension of the second retaining ring 415 adjustable, so as to facilitate the installation of the connecting shaft 412 into the connecting seat 2 through the first through hole 211.

[0091] In addition, in some other embodiments of the present application, the connecting shaft 412 of the massage part 41 may not be connected to the clamping arm 1 through the connecting seat 2, but the connecting shaft 412 is directly fixedly connected to the second cover body 112 of the clamping arm 1, and when the clamping arm 1 is rotated and folded, the massage part 41 will naturally be driven to rotate and fold together; when the clamping distance between the two clamping arms 1 is enlarged, the distance between the two massage parts 41 will naturally be enlarged.

[0092] Furthermore, three, four or more massage parts 41 may be provided; at least part of the massage part 41 may be connected to the clamping arm 1 via the connecting seat 2, or at least part of the massage part 41 may be directly fixedly connected to the second cover 112 of the clamping arm 1. The connection relationship has been described in detail above, so it will not be repeated here.

[0093] The massager may further include an adjusting mechanism, which is disposed on the two clamping arms 1 and is used to adjust the clamping distance between the two clamping arms 1 .

[0094] Specifically, the adjustment mechanism may include an elastic member connected between the two connecting shafts 412. Figure 1 and Figure 2 As shown, the elastic member can be an elastic ring 5 sleeved outside the two connecting shafts 412. In addition, the elastic member can also be a tension spring connected between the two connecting shafts 412, and the stretching direction (installation direction) of the tension spring is consistent with the extension direction of the first groove 13.

[0095] Reference Figure 8The schematic diagram of the structure of the massager in the unfolded state is shown. When the user is using it, the user can hold the two clamping arms 1 with both hands respectively, and pull the two clamping arms 1 to both sides with force. The rotating shafts 12 of the two clamping arms 1 will drive the connecting shaft 412 of the massage part 41 to slide outward, and the rotating shaft 12 slides along the second through hole 221, and the connecting shaft 412 slides along the first through hole 211. The positioning block 33 will also slide outward in the first groove 13, so that the distance between the two connecting shafts 412 will increase, and the elastic ring 5 sleeved outside the two connecting shafts 412 will be expanded to generate an inward contraction force (the tension spring connected between the two connecting shafts 412 will be pulled apart to generate an inward contraction force), and the distance between the two rotating shafts 12 will also increase, so that the clamping distance between the two clamping arms 1 increases to form a shape as shown in the figure. Fig. 9 The massager is shown in the state of maximum clamping distance, and the arrow in the figure indicates the adjustment direction. After the user wears it on the neck, under the action of the contraction force of the elastic ring 5 (or tension spring), the connecting shafts 412 of the two massage parts 41 will slide inward in the first through hole 211, the rotating shafts 12 of the two clamping arms 1 will slide inward in the second through hole 221, and the positioning block 33 will also slide inward in the first groove 13, so that the distance between the two connecting shafts 412 will decrease, and the distance between the two rotating shafts 12 will also decrease until the size that matches the user's massaged part (for example, the neck, waist and abdomen, limbs, head, etc.) is reached. Since the sizes of the massaged parts of different users are different, the two clamping arms 1 are clamped on the massaged parts of the user. Therefore, the clamping distance X between the two clamping arms 1 will vary with the sizes of the massaged parts of the user to adapt to different users.

[0096] The structure of the adjustment mechanism is not limited to the above description. For example, the adjustment mechanism may include two compression springs, which are correspondingly arranged between the two connecting shafts 412 and the connecting seat body 21, that is, the compression spring and the tension spring are arranged on opposite sides of the connecting shaft 412, and the compression direction (installation direction) of the two compression springs is consistent with the extension direction of the first groove 13. When the user pulls the two clamping arms 1 apart, the compression spring is compressed to generate an outward extension force. After the user releases the two clamping arms 1, the compression spring will push the connecting shaft 412 to move inward until it reaches a size that matches the user's massaged part (e.g., neck, waist, abdomen, limbs, head, etc.).

[0097] The above describes the case where only one of the elastic ring 5, tension spring and compression spring is provided. It should be noted that the adjustment mechanism may include two or three of the elastic ring 5, tension spring and compression spring, that is, the elastic ring 5, tension spring and compression spring may be provided at the same time, or the elastic ring 5 and tension spring may be provided at the same time, or the elastic ring 5 and compression spring may be provided at the same time, or the tension spring and compression spring may be provided at the same time.

[0098] In addition, when the connecting shaft 412 is directly fixedly connected to the second cover body 112 of the clamping arm 1, the elastic ring 5 can be sleeved outside the two rotating shafts 12, the tension spring can be connected between the two connecting shafts 412, and the two compression springs are correspondingly arranged between the two rotating shafts 12 and the connecting seat body 21.

[0099] In one embodiment, when the massager is in the unfolded state, the spacing X (clamping distance) between the two clamping arms 1 is greater than or equal to 45 mm and less than or equal to 75 mm, and the spacing X (clamping distance) between the two clamping arms 1 refers to the minimum spacing between the two clamping arms 1. Of course, different clamping spacings X can be set according to different use parts of the massager.

[0100] It should be noted that when changing the massager from the unfolded state to the folded state, the two clamping arms 1 need to be pulled apart to both sides by a certain distance first to avoid mutual interference between the two clamping arms 1; and then the two clamping arms 1 are rotated with force.

[0101] In order to avoid having to pull the two clamping arms 1 apart a certain distance before changing the massager from the unfolded state to the folded state, the end of the clamping arm 1 closer to the other clamping arm 1 can be set to an arc shape with the central axis of the rotating shaft 12 as the central axis, so as to avoid mutual interference between the two clamping arms 1.

[0102] It should be noted that although several components, modules or mechanisms of the massager are mentioned in the above detailed description, such division is merely exemplary and not mandatory. In fact, according to the embodiments of the present application, the features and functions of two or more components, modules or mechanisms described above can be embodied in one component, module or mechanism. Conversely, the features and functions of one component, module or mechanism described above can be further divided into multiple components, modules or mechanisms.

[0103] Although the spirit and principle of the present application have been described with reference to several specific embodiments, it should be understood that the present application is not limited to the disclosed specific embodiments, and the division of various aspects does not mean that the features in these aspects cannot be combined to benefit, and such division is only for the convenience of expression. The present application is intended to cover various modifications and equivalent arrangements included in the spirit and scope of the attached claims.
