Description

Technical Field

[0001] The present invention relates to the technical field of massagers, and in particular to a cervical massager. Background Art

[0002] The cervical vertebra refers to the part located below the head and above the thoracic vertebrae that enables the human neck to move flexibly. As the human body ages, the lower cervical vertebrae used to connect to the thoracic vertebrae are prone to degenerative changes, which leads to the narrowing of the intervertebral space and the reduction of the intervertebral foramen. At the same time, bone spurs are prone to grow on the edges of the vertebrae, compressing the roots of the spinal nerves and causing cervical spondylosis. In order to relieve cervical spondylosis, a large number of neck massagers have appeared on the market, mainly by setting a massage head on the inner side of the wearing bracket of the neck massager. When the user puts the neck massager on the neck, the massage head can contact the user's neck to achieve a neck massage for the user. However, the massage head of the current neck massager is usually used to massage the neck muscle groups on both sides of the human cervical spine, which cannot meet the user's massage needs for the cervical spine.

[0052] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0053] Embodiment 1

[0054] Please also read Figures 1 to 3The present invention discloses a cervical massager 100, comprising a wearing bracket 11 and a middle massage head 12. The wearing bracket 11 is configured to have a C-shape and a forward opening 111, so as to be worn on the human neck. The middle massage head 12 comprises a fixing seat 12a and a massage sheet 12b, wherein the fixing seat 12a is connected to the inner side 110 of the wearing bracket 11 and is located in the middle of the C-shape, and the massage sheet 12b is arranged on the side of the fixing seat 12a away from the wearing bracket 11, and along the width direction of the wearing bracket 11, the massage sheet 12b is in an arc shape with the middle part convex inward and the two sides bent outward (such as Figure 3 As shown by the bold curved lines in Figure 3 In the figure, the middle part of the massage sheet 12b is blocked by the wearing bracket 11, so it is shown with a bold arc dotted line) to fit the cervical vertebra of the human body.

[0055] The wearing bracket 11 is C-shaped, and its length direction is the direction from the starting end to the end of the C-shape, and the width direction of the wearing bracket 11 is the direction between the inner side 110 of the wearing bracket 11 and the outer side 112 of the wearing bracket 11. Specifically, the inner side 110 of the wearing bracket 11 refers to the side of the wearing bracket 11 facing the human neck, that is, the inner side of the arc of the C-shape, and the outer side 112 of the wearing bracket 11 is the side away from the human neck, that is, the side outside the opening 111.

[0056] For example, Figure 1 For ease of description, Figure 1 The up-down and left-right directions of the cervical massager 100 are shown in FIG. Figure 1 The up-down and left-right directions in the figure are all paper directions. Figure 1 The direction from left to right on the paper is the length direction of the wearing bracket, and Figure 1 The direction from top to bottom on the paper is the width direction of the wearing bracket. Figure 1 Projecting from top to bottom, we get Figure 2 ,Depend on Figure 1 Projecting from right to left, we get Figure 3 .

[0057] It can be understood that the massage sheet 12b is in an arc shape along the width direction of the wearing bracket 11, with the middle part convex inward and the two sides bent outward. The direction of the inward convexity is the same as the inner direction of the wearing bracket, and the direction of the outward bending is the same as the outer direction of the wearing bracket.

[0058] Since the human neck is not an absolute cylindrical shape, but a shape in which the diameter decreases first and then increases from top to bottom, the embodiment of the present invention adopts a middle massage head 12 set on the wearing bracket 11, and the length direction of the middle massage head 12 is along the width direction of the wearing bracket 11, and the projection of the massage sheet 12b of the middle massage head 12 along the width direction of the wearing bracket 11 is an arc shape with the middle part convex inward and the two sides bent outward, which can effectively adapt to the shape of the human cervical spine, better fit, and effectively improve the massage effect. At the same time, the outward bending on both sides can also make way for the muscles of the head, neck and shoulders located around the cervical spine, effectively preventing the situation in which the user may press against the middle massage head 12 when raising his head during the use of the cervical massager 100, thereby improving the practical comfort of the user, and also filling the gap of the defect of not setting a special massage head for the user's cervical spine in the related art.

[0059] Furthermore, in the projection along the length direction of the wearing bracket 11, the massage sheet 12b is in an arc shape with the middle portion concave outward and the two sides bent inward (such as Figure 2 The shape design is based on the following: since the outer contour surface of the human neck is approximately a cylindrical side surface, the concave design of the massage sheet 12b can be adapted to the outer contour surface of the user's neck when the user uses it, so as to better fit the outer contour surface of the user's neck skin and enhance the massage effect.

[0060] The outward concave middle portion refers to being concave toward the outer side of the wearing bracket, and the inward curvature of the two sides refers to being curved inward along the inner side of the wearing bracket.

[0061] It can be seen from this that the present invention designs the shape of the massage sheet 12b of the middle massage head 12 so that its projection shape in the length direction of the wearing bracket 11 is concave in the middle and curved outward on both sides, while its projection shape in the width direction of the wearing bracket is an arc with a convex middle and curved outward on both sides, thereby effectively matching the shape of the user's cervical spine and ensuring that the massage sheet 12b can fit the user's cervical spine skin, thereby transmitting massage to the user's cervical spine.

[0062] In some embodiments, the wearing bracket 11 includes an intermediate bracket 1a and two handles 1b and 1c, the two handles 1b and 1c are connected to the two ends of the intermediate bracket 1a in the length direction, and the intermediate massage head 12 is arranged on the side of the intermediate bracket 1a facing the human neck, that is, the intermediate massage head 12 is arranged on the inner side 110 of the intermediate bracket 1a. The two handles 1b and 1c are used to bear against the user's shoulders when the user wears the neck massager 100, so as to position the intermediate bracket 1a across the user's neck.

[0063] In some embodiments, the middle bracket 1a may include a first surface 113 along the width direction of the wearing bracket 11 and a second surface 114 opposite to the first surface 113, and both sides of the middle massage head 12 in the length direction extend out of the first surface 113 and the second surface 114. Specifically, both sides of the fixing seat 12a and the massage sheet 12b in the length direction extend out of the first surface 113 and the second surface 114.

[0064] The design adopts that the first surface 113 and the second surface 114 extend out from both sides of the fixed base 12a and the massage sheet 12b in the length direction respectively. When the cervical massager 100 is placed or stored on a plane, one end of the massage sheet 12b extending out from the first surface 113 or the second surface 114 contacts the plane on which it is placed, thereby preventing the wearing bracket 11 from being placed directly on the plane, which is beneficial to keeping the surface of the wearing bracket 11 clean and reducing the surface wear of the wearing bracket 11, thereby extending the service life of the wearing bracket 11.

[0065] Combination Figure 4 As shown, further, in order to effectively support the wearing bracket 11 when the cervical massager 100 is placed on a plane, and prevent the cervical massager 100 from shaking when placed, the fixing seat 12a may have a supporting surface 120, and the supporting surface 120 may be a plane (such as Figure 4 ), and the support surface 120 can be flush with the upper surface or lower surface of other positions of the wearing bracket 11 (such as the handle), which can increase the contact area of ​​the neck massager with the plane on which it is placed, thereby improving the stability of the neck massager 100 when placed.

[0066] Among them, the support surface 120 is a side surface of the fixing seat 12a extending from the second surface 114, or a side surface extending from the first surface 113, or, a side surface of the fixing seat 12a extending from the second surface 114 and a side surface of the fixing seat 12a extending from the first surface 113 are both the support surface 120.

[0067] In this way, no matter the user places the cervical massager 100 from top to bottom or from bottom to top, the support surface 120 can be used to effectively support the wearing bracket 11, avoiding the wearing bracket 11 from directly contacting the placement plane and effectively preventing the wearing bracket 11 from shaking.

[0068] Optionally, the length of the massage sheet 12b may be H, wherein 30 mm ≤ H ≤ 60 mm, that is, H may be 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm or 60 mm, etc.

[0069] Considering that if the massage sheet 12b is too long, although it can increase the contact surface area with the user, when the user straightens his neck normally, the massage sheet 12b may hit the user's neck skin or muscles located at the upper and lower parts of the cervical spine, causing pain to the user and restricting the movement of the user's neck. If the massage sheet 12b is too short, although it can avoid the above-mentioned problem of hitting the user's neck skin or muscles, it cannot guarantee the contact area between the massage sheet 12b and the user's massage part, and cannot meet the user's massage needs. Therefore, based on the above considerations, when setting the massage sheet 12b, the length H of the massage sheet 12b is set to the above value, which can not only ensure the fitting area between the massage sheet 12b and the user's cervical spine, but also will not hit the user's neck skin or muscles when the user straightens his neck normally, effectively avoiding the situation of causing pain to the user and restricting the normal movement of the user's neck, conforming to the ergonomic design, and more comfortable for users to wear and use.

[0070] Please also read Figures 5 to 8 , further, the fixing seat 12a of the middle massage head 12 includes a shell 121 and a support plate 122, the massage sheet 12b is connected to the shell 121 and forms a receiving cavity 121a with the shell 121, and the support plate 122 is arranged in the shell 121 and is located in the receiving cavity 121a. Optionally, the massage sheet 12b can be connected to the shell 121 by threaded connection, bonding or snap connection. In this embodiment, the massage sheet 12b can be connected to the shell 121 by snap connection, specifically: an installation gap 121b is defined between the outer peripheral edge of the support plate 122 and the outer peripheral edge of the shell 121, and a flange 123 extends from the side surface of the massage sheet 12b facing the shell 121, and the flange 123 can be snapped in the installation gap 121b.

[0071] More specifically, the installation gap 121b can be an annular gap around the outer circumference of the support plate 122, and the flange 123 on the massage sheet 12b can be an annular flange. The flange 123 is clamped in the annular gap to facilitate the quick connection between the massage sheet 12b and the housing 121.

[0072] In order to further enhance the connection reliability and tightness between the massage sheet 12b and the shell 121 and prevent the massage sheet 12b from being separated from the shell 121 and the support plate 122 during use, one or more notches 122a with the opening 111 facing outward are provided on the outer peripheral edge of the support plate 122. Correspondingly, one or more folding pieces 123a are protruding upward on the flange 123 of the massage sheet 12b. The folding pieces 123a can be arranged corresponding to the notches 122a, and the folding pieces 123a can be bent downward from the flange 123 of the massage sheet 12b to be located in the notch 122a corresponding thereto.

[0073] Specifically, the notch 122 a may extend from the outer periphery of the support plate 122 to the middle of the support plate 122 , and the notch 122 a is located on a surface of the support plate 122 facing the housing 121 .

[0074] With such a setting, when the flange 123 of the massage sheet 12b is stuck in the installation gap 121b, the folded piece 123a can be bent into the notch 122a on the support plate 122, so that the connection between the support plate 122 and the shell 121 can be utilized, so that the folded piece 123a can be firmly fixed between the support plate 122 and the shell 121, thereby effectively preventing the flange 123 from falling out of the installation gap 121b, and effectively improving the installation firmness and reliability of the massage sheet 12b, the shell 121, and the support plate 122.

[0075] Optionally, the number of the notches 122a may be at least two, such as two, three, four or more. When the number of the notches 122a is two, the two notches 122a may be arranged on different sides of the outer circumference of the support plate 122. Similarly, the number of the flaps 123a may also be at least two, which may be arranged corresponding to the positions of the notches 122a.

[0076] Please also read Figure 5 , Figure 6 , Fig. 9 and Fig.10 In this embodiment, the middle massage head 12 can be a heating massage head, which can play a role of hot compress massage. The middle massage head 12 also includes a heating component 12c, which can be set on the support plate 122 and abut against the massage sheet 12b, so that the heating component 12c can be used to heat the massage sheet 12b, and the massage sheet 12b is used to transfer heat to the user's cervical spine to achieve a hot compress massage effect. Specifically, the heating component 12c can be a heating wire, a heating tube or a heating sheet, etc. The heating component 12c can be fixed on the support plate 122 by bonding, and abut against the massage sheet 12b, so that heat can be directly transferred to the massage sheet 12b.

[0077] Furthermore, in order to effectively transfer heat and reduce heat loss, the massage sheet 12b can be made of a heat conductive sheet, that is, its material can be made of metal, heat conductive silicone, etc.

[0078] Furthermore, in order to effectively ensure the abutting force between the heating component 12c and the massage sheet 12b, an elastic component 122b can be provided on the support plate 122, and the heating component 12c is provided on the elastic component 122b, so that the elastic component 122b can provide a longitudinal extrusion force to the heating component 12c to keep the heating component 12c in an abutting state with the massage sheet 12b.

[0079] Optionally, the elastic component 122b can be made of elastic materials such as silicone, rubber or foam.

[0080] As an optional embodiment, a silicone pad can be used for the elastic component 122b. Thus, on the one hand, the silicone pad has good heat insulation performance and can reduce the heat transfer of the heating component 12c downward (i.e., toward the support plate 122 and the shell 121); on the other hand, the silicone pad has good elastic deformation performance and can firmly press the heating component 12c against the massage sheet 12b, thereby making the abutment between the heating component 12c and the massage sheet 12b tighter and the heat transfer more direct.

[0081] As another optional embodiment, the elastic component 122b can also be made of foam, so that the foam can always be in a compressed state to ensure the effective surface-to-surface contact between the heating component 12c and the massage sheet 12b, which facilitates the heat transfer from the heating component 12c to the massage sheet 12b. In addition, the foam also has good thermal insulation performance, which can effectively keep warm, reduce heat loss, and improve heat utilization. Moreover, the foam can also effectively insulate and reduce the heat transfer downward (i.e., toward the support plate 122 and the housing 121), thereby effectively avoiding the overall overheating of the middle massage head 12.

[0082] It is understandable that, in other embodiments, the elastic component 122b may also be made of other materials with elastic properties, such as sponge, pearl cotton, etc.

[0083] Optionally, the elastic component 122b can be configured in an H-shape, a Z-shape, or an N-shape, so as to facilitate the routing design of the heating component 12c. Specifically, when the elastic component 122b is configured in an H-shape or an N-shape, notches can be formed on its upper and lower sides for routing the heating component 12c. When the elastic component 122b is configured in a Z-shape, notches can be formed on its left and right sides for routing the heating component 12c.

[0084] It is understandable that, in other embodiments, the elastic component 122b may not be limited to the above structure, for example, it may be S-shaped, W-shaped, etc., and may be specifically set according to the designed routing position, which is not specifically limited in this embodiment.

[0085] In addition, in order to facilitate the routing of the heating component 12c, the shape of the heating component 12c can match the shape of the elastic component 122b, that is, when the elastic component 122b is configured into an H shape, a Z shape, or an N shape, the heating component 12c is also configured into an H shape, a Z shape, or an N shape.

[0086] Furthermore, the middle massage head 12 may also include an expansion sheet 12d, which is provided with medicine and / or aromatherapy agents. The expansion sheet 12d is detachably connected to the massage sheet 12b, so that the massage sheet 12b can transfer heat to the expansion sheet 12d to heat the medicine and / or aromatherapy agents.

[0087] The expansion sheet 12d refers to a sheet that can be installed on the massage sheet 12b and is used to contact the user's cervical spine. With the design of the expansion sheet 12d, the massage sheet 12b with different physiotherapy functions can be replaced according to the different usage requirements of the user.

[0088] As an optional embodiment, only medicine can be set on the expansion piece 12d, and the medicine can be a medicine with therapeutic effect set according to different user needs, such as certain Chinese herbal powders (such as mugwort, cassia seed, etc.), ointments or patch-type medicines.

[0089] Optionally, the medicine can be in the form of a medicine package, that is, one or more Chinese herbal medicines are ground into powder and then packed in a packaging bag to form a medicine package. When the medicine is arranged on the expansion sheet 12d, the medicine package can be arranged inside the expansion sheet 12d.

[0090] Optionally, the drug may also be a paste-like drug. If a paste-like drug is used, the drug can be directly applied to the expansion sheet 12d.

[0091] Optionally, the drug may also be a patch-type drug. When a patch-type drug is used, the drug may be directly pasted on the expansion sheet 12d.

[0092] As another optional implementation, an aromatherapy agent may be provided on the expansion sheet 12d, wherein the aromatherapy agent, an aromatherapy patch or an aromatherapy bag may be selected.

[0093] Optionally, the aromatherapy may be an aromatherapy agent. When arranged on the expansion sheet 12d, a cavity may be formed inside the expansion sheet 12d, and then the aromatherapy agent may be arranged in the cavity of the expansion sheet 12d.

[0094] Optionally, the aromatherapy may use an aromatherapy patch, and during setting, the aromatherapy patch may be placed on the expansion sheet 12d.

[0095] Optionally, the aromatherapy may also use an aromatherapy bag, and during setting, the aromatherapy bag may be set in the expansion piece 12d.

[0096] As another optional implementation, medicine and aromatherapy may also be provided on the expansion piece 12d at the same time.

[0097] By adopting the method of setting medicine and / or aromatherapy on the expansion sheet 12d, when the expansion sheet 12d is installed on the massage sheet 12b, on the one hand, it replaces the traditional method of directly sticking, applying or smearing medicine and / or aromatherapy on the user's skin, and solves the problems of medicine residue on the user's skin and medicine easily falling off the user's skin when sweating. On the other hand, the massage sheet 12b can transfer the heat of the heating component 12c to heat the expansion sheet 12d, which can heat the medicine and / or aromatherapy on the expansion sheet 12d, accelerate the volatilization of the medicine and / or aromatherapy, and enhance the drug treatment and aromatherapy effects.

[0098] From the above, it can be seen that the massage sheet 12b is used to match the user's cervical spine position. Therefore, in the length direction of the middle bracket 1a, the massage sheet 12b is in the shape of an arc with a middle portion concave inward and two sides bent outward. At the same time, in the width direction of the middle bracket 1a, the massage sheet 12b is in the shape of an arc with a middle portion convex outward and two sides bent inward. Therefore, in order for the expansion sheet 12d to be able to adapt to the user's cervical spine position, the shape of the expansion sheet 12d should be consistent with the shape of the massage sheet 12b, that is, in the length direction of the middle bracket 1a, the expansion sheet 12d is in the shape of an arc with a middle portion concave inward and two sides bent outward. At the same time, in the width direction of the middle bracket 1a, the expansion sheet 12d is in the shape of an arc with a middle portion convex outward and two sides bent inward.

[0099] Optionally, the detachable connection between the expansion sheet 12d and the massage sheet 12b may include a combination of one or more connection methods including a snap connection, a nested connection, a connection through a peelable adhesive, or a magnetic connection.

[0100] Specifically, the massage sheet 12b has a first surface 124, and the first surface 124 is a surface of the massage sheet 12b facing away from the fixing seat 12a.

[0101] As an optional embodiment, the expansion sheet 12d can be attached to the first surface 124 of the massage sheet 12b by means of a peelable adhesive. That is, one side of the expansion sheet 12d is attached to the first surface 124 of the massage sheet 12b by means of an adhesive.

[0102] As another optional embodiment, the expansion sheet 12d can be magnetically attached to the massage sheet 12b. Specifically, a first magnetic member 125 with a first polarity can be provided on the expansion sheet 12d, and a second magnetic member 126 with a second polarity can be correspondingly provided on the massage sheet 12b. The magnetic attraction forces of the first magnetic member 125 and the second magnetic member 126 can be used to achieve a detachable connection between the expansion sheet 12d and the massage sheet 12b.

[0103] In the specific setting, in order to save space, the second magnetic component 126 can be set in the accommodating cavity 121a, and specifically can be set on both sides of the elastic component 122b. In this way, as long as the expansion piece 12d is close to the massage piece 12b, the expansion piece 12d can be adsorbed on the massage piece 12b due to the magnetic force of the first magnetic component 125 and the second magnetic component 126.

[0104] As another optional embodiment, the expansion sheet 12d can be connected to the massage sheet 12b by snapping. Specifically, a mounting groove 127 can be provided on the first surface 124 of the massage sheet 12b, and the expansion sheet 12d is snapped into the mounting groove 127 to achieve the connection between the expansion sheet 12d and the massage sheet 12b.

[0105] Specifically, the first surface 124 of the massage sheet 12 b may be recessed to form a mounting groove 127 that matches the shape of the expansion sheet 12 d , so that the expansion sheet 12 d may be installed in the mounting groove 127 .

[0106] In this way, since the expansion piece 12d is installed in the installation groove 127 formed by the depression of the massage piece 12b, the expansion piece 12d does not increase the overall thickness of the middle massage head 12, so that the middle massage head 12 can maintain a light and thin design.

[0107] As another optional embodiment, the expansion sheet 12d can be directly sleeved on the first surface 124 of the massage sheet 12b. Specifically, a nesting edge can be extended and provided on the outer periphery of the expansion sheet 12d, and the nesting edge and the expansion sheet 12d itself form a receiving groove (not shown) with an opening 111, and the opening 111 of the receiving groove is aligned with the massage sheet 12b so that the massage sheet 12b can be just stuck in the receiving groove, that is, the expansion sheet 12d is sleeved on the first surface 124 of the massage sheet 12b through the nesting edge. More specifically, in order to facilitate installation and replacement, the nesting edge can be made of an elastic material, such as silicone, rubber, etc.

[0108] The design in which the expansion piece 12d is directly nested in the massage piece 12b is adopted. On the one hand, it is convenient for disassembly and assembly, and on the other hand, it can ensure that when the middle massage head 12 is in use, the expansion piece 12d has sufficient contact area with the user's massaged part to ensure the massage effect.

[0109] In this embodiment, the expansion piece 12d is preferably installed in the installation groove 127 of the massage piece 12b, and the first magnetic component 125 and the second magnetic component 126 are magnetically connected to each other to effectively ensure the connection reliability between the expansion piece 12d and the massage piece 12b, thereby avoiding the expansion piece 12d from falling off during the massage process.

[0110] Please also read Figures 11 to 13Optionally, the middle bracket 1a may include an elastic bracket 11a and a plastic bracket 11b, both of which are configured in a C shape, and the plastic bracket 11b may be connected to the elastic bracket 11a to form a hollow space between the two to accommodate a circuit board and other functional devices. The middle massage head 12 may be fixed to the inner side 110 of the elastic bracket 11a. That is, the inner side 110 of the elastic bracket 11a forms the inner side 110 of the wearing bracket 11, and the outer side 112 of the plastic bracket 11b forms the outer side 112 of the wearing bracket 11.

[0111] Optionally, the elastic bracket 11a may be made of rubber, silicone or other materials.

[0112] Furthermore, when the middle massage head 12 is mounted on the elastic bracket 11a, the connection can be achieved through the elastic connecting column 110a provided on the elastic bracket 11a. Specifically, an elastic connecting column 110a is convexly provided on the inner side 110 of the elastic bracket 11a facing the direction of the C-shaped opening 111, and the elastic connecting column 110a can be made of silicone. The elastic connecting column 110a can be formed into a hollow column, and the fixing seat 12a of the middle massage head 12 can be fixed to the elastic connecting column 110a, so that the middle massage head 12 is fixed on the inner side 110 of the elastic bracket 11a. Specifically, a clamping member 1101 can be provided in the hollow part of the elastic connecting column 110a, and a protruding fixing portion 1211 can be provided on the housing 121 of the fixing seat 12a corresponding to the clamping member 1101, and the fixing portion 1211 can extend into the hollow part of the elastic connecting column 110a and be fixedly connected with the clamping member 1101.

[0113] Furthermore, the inner wall surface and / or the outer wall surface of the elastic connecting column 110a may be recessed inward to form an annular recess 1102, thereby reducing the inner wall thickness of the elastic connecting column 110a, so that the deformation capacity of the elastic connecting column 110a can be improved. When the user wears the cervical massager 100, the middle massage head 12 abuts against the user's cervical vertebra, and the user's cervical vertebra pressure is applied to transmit the pressure to the elastic connecting column 110a, so that the elastic connecting column 110a can be elastically deformed to achieve the floating of the middle massage head 12, thereby improving the fitting ability of the middle massage head 12, so that the middle massage head 12 is always firmly fitted to the user's cervical vertebra, and the fit is high. In addition, since the bracket where the elastic connecting column 110a is located is an elastic bracket 11a, it can also be elastically deformed to further improve the ability of the middle massage head 12 to follow the deformation of the user's cervical vertebra shape.

[0114] In an optional implementation, one or more annular recesses 1102 may be provided on the inner wall surface of the elastic connecting column 110a, so as to reduce the thickness of the inner wall surface of the elastic connecting column 110a and increase its elastic deformation capacity.

[0115] In another optional implementation, one or more annular recesses 1102 may be provided on the outer wall surface of the elastic connecting column 110a, so as to reduce the thickness of the outer wall surface of the elastic connecting column 110a and increase its elastic deformation capacity.

[0116] As another optional embodiment, one or more annular recesses 1102 are provided on both the inner wall and the outer wall of the elastic connecting column 110a. It is understandable that the positions of the annular recesses 1102 formed on the inner wall of the elastic connecting column 110a and the annular recesses 1102 formed on the outer wall of the elastic connecting column 110a can be arranged relative to each other or staggered. In order to ensure the structural strength of the elastic connecting column 110a and meet the bearing strength of the middle massage head 12, the positions of the annular recesses 1102 formed on the inner wall of the elastic connecting column 110a and the annular recesses 1102 formed on the outer wall of the elastic connecting column 110a can be staggered.

[0117] Furthermore, when the annular depression 1102 is formed on the elastic connecting column 110a, the thinnest thickness of the elastic connecting column 110a after the annular depression 1102 is formed should be not less than 0.5 mm. If the thinnest thickness of the elastic connecting column 110a after the annular depression 1102 is formed is less than 0.5 mm, the thickness at that location is very small, and the elastic deformation capacity is small, and the deformation capacity of the floating of the middle massage head 12 cannot be effectively provided. In addition, since the annular depression 1102 formed on the elastic connecting column 110a is mainly formed in one piece when the elastic connecting column 110a is formed, due to the poor fluidity of the silicone during molding, a certain distance is required to ensure that the elastic connecting column 110a will not be partially short of material. Therefore, based on the above considerations, the thinnest thickness of the elastic connecting column 110a after the annular depression 1102 is formed should be not less than 0.5 mm. Optionally, the thinnest thickness of the elastic connecting column 110a after the annular recess 1102 is formed may be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0118] Furthermore, the elastic connection column 110a may be in a table shape with a width gradually increasing from the end connected to the fixing seat 12a to the end close to the inner side 110 surface of the elastic bracket 11a. The table-shaped design of the elastic connection column 110a can increase the structural strength of the connection between it and the elastic bracket 11a, so that after the cervical massager 100 is used for a long time, the connection between the elastic connection column 110a and the elastic bracket 11a is still not prone to fatigue damage.

[0119] The cervical massager 100 disclosed in the first embodiment of the present invention can effectively adapt to the shape of the human cervical spine, better fit, and effectively improve the massage effect by arranging a middle massage head 12 on the wearing bracket 11, and the massage piece 12b of the middle massage head 12 is in an arc shape along the width direction of the wearing bracket 11 with the middle part convex inward and the two sides bent outward.

[0120] In addition, the middle massage head 12 is a heating massage head, in which a heating component 12c is arranged inside. At the same time, an expansion sheet 12d is detachably arranged on the massage sheet 12b. The heating component 12c can be used to heat the medicine and / or aromatherapy agent on the expansion sheet 12d to accelerate volatilization, thereby effectively improving the massage and soothing effect.

[0121] Embodiment 2

[0122] Please also read Figure 14 to Figure 15 , is a schematic diagram of the structure of a cervical massager disclosed in Embodiment 2 of the present invention. The difference between the cervical massager 200 disclosed in Embodiment 2 of the present invention and the cervical massager 100 in Embodiment 1 is:

[0123] The cervical massager 200 of the present invention may further include a first massage head 21 and a second massage head 22, both of which are arranged on the inner side 110 of the wearing bracket 11 and are respectively located on both sides of the middle massage head 12. Specifically, in the actual arrangement, the first massage head 21, the middle massage head 12 and the third massage head are arranged in sequence from left to right along the length direction of the wearing bracket 11. In this way, when the user wears and uses the cervical massager 200, the first massage head 21 can massage the muscles on the left side of the user's neck, the middle massage head 12 can massage the user's cervical spine, and the second massage head 22 can massage the muscles on the right side of the user's neck, thereby realizing that a cervical massager 200 can massage different neck positions at the same time, meet the user's massage needs for different neck positions, and improve the user experience.

[0124] Furthermore, the first massage head 21, the middle massage head 12 and the second massage head 22 are arranged in sequence along the arc direction of the C shape. The extension length direction of the first massage head 21 and the second massage head 22 is along the length direction of the wearing bracket 11, and the length direction of the middle massage head 12 is along the width direction of the wearing bracket 11.

[0125] By adopting the above method, when the size of the wearing bracket 11 is certain, on the one hand, the sum of the massage surface areas of the three massage heads can be made larger, the massage area can be increased, and the massage effect can be improved; on the other hand, it can effectively avoid crowding or interference between the massage heads.

[0126] Furthermore, the middle massage head 12 can be arranged in the middle of the C-shape, and the center of the middle massage head 12 coincides with the center of the C-shape, while the first massage head 21 and the second massage head 22 can be arranged symmetrically about the middle of the C-shape, so that the distance from the first massage head 21 to the middle massage head 12 is equal to the distance from the second massage head 22 to the middle massage head 12. In this way, the weight of the left and right sides of the cervical massager 200 can be kept balanced, so that the center can be located on the central axis of the cervical massager 200, thereby avoiding the imbalance when the user wears it and the situation that it is not securely worn and easy to loosen due to leaning to one side, thereby avoiding the discomfort of wearing, and effectively ensuring the wearing comfort and reliability of the user.

[0127] Optionally, the distance between the first massage head 21 and the middle massage head 12 is H1, and the distance between the second massage head 22 and the middle massage head 12 is H2, then 2mm≤H1=H2≤10mm, preferably 5≤H1=H2≤8mm. That is, H1 and H2 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm, etc.

[0128] The distance refers to the distance from the first massage head 21 to the middle massage head 12 and the distance from the second massage head 22 to the middle massage head 12 along the length direction of the wearing bracket 11 .

[0129] The above distances H1 and H2 are in this range based on: considering that the size of the wearing bracket 11 is certain, in order to ensure that the positions of the three massage heads can match the different neck positions of the user to achieve massage, and at the same time the three massage heads cannot touch each other to avoid interference. Therefore, by adopting the above range, it can be ensured that the three massage heads will not touch each other during wearing, and the distance between them will not be too large, avoiding the situation where the first massage head 21 and the second massage head 22 on the left and right sides may be aligned with the arteries on both sides of the human neck, effectively ensuring the safety of the cervical massager 200.

[0130] Furthermore, the first massage head 21 has a first massage surface 210, the middle massage head 12 has a middle massage surface 1200, and the second massage head 22 has a second massage surface 220. In the projection in the length direction of the wearing bracket, the projections of the first massage surface 210, the middle massage surface 1200 and the second massage surface 220 are approximately located on the same arc 300 (e.g. Fig.15 The arc 300 is approximately coincident with the outer contour of the human neck. The first massage surface 210, the middle massage surface 1200 and the second massage surface 220 are the surfaces for contacting the user's neck. The arc 300 may be a circular arc, the center of which may coincide with the center of the C-shape.

[0131] With such a setting, when worn, it can ensure that the massage surfaces of the first massage head 21, the middle massage head 12 and the second massage head 22 can all contact and fit completely with the user's neck, avoiding the situation where the massage surface of one of the massage heads does not fit tightly or does not fit the user's neck, causing pain or ineffective massage, thereby improving the massage effect and further improving the user experience.

[0132] In some embodiments, considering that the first massage head 21 and the second massage head 22 are used to massage the left side and the right side of the user's neck respectively, that is, the first massage head 21 and the second massage head 22 are both used to massage the user's neck muscles, and the middle massage head 12 is used to massage the cervical vertebrae, therefore, the first massage head 21 and / or the second massage head 22 can be a pulse massage head, and the middle massage head 12 can be a heating massage head. Optionally, in actual design, the first massage head 21 can be a pulse massage head, and the second massage head 22 can also be a heating massage head, or the first massage head 21 can be a heating massage head, and the second massage head 22 can be a pulse massage head. Alternatively, the first massage head 21 and the second massage head 22 are both pulse electrode heads.

[0133] Considering that the first massage head 21 and the second massage head 22 are used to massage the left side and the right side of the user's neck respectively, that is, the first massage head 21 and the second massage head 22 are both used to massage the user's neck muscles, and the middle massage head 12 is used to massage the cervical vertebrae, therefore, the first massage head 21 and the second massage head 22 can be set as pulse massage heads, and the middle massage head 12 can be a heating massage head. In this way, on the one hand, the first massage head 21 and the second massage head 22 use pulse electrotherapy massage to just stick to the muscles on both sides of the user's neck and cervical vertebrae, which is the part that needs electric massage to relieve fatigue, and the middle massage head 12 can just heat the spine (i.e., the cervical vertebrae), which is based on the fact that the human cervical vertebrae are mostly bones, and the use of pulse electrotherapy stimulation is easy to cause tingling and discomfort, so the middle massage head 12 is set as a heating massage head, which can just apply heat to the spine to achieve a soothing effect. In addition, the length of the massage sheet of the first massage head 21 and the second massage head 22 extends along the length direction of the wearing bracket 11, which can cover the muscles around the neck to a large extent, and the length of the massage sheet of the middle massage head 12 located in the middle extends along the width direction of the wearing bracket, and the middle massage head 12 is arranged on the middle bracket 1a in a vertical direction toward the user's neck side, so that heating can be performed along the extension direction of the human spine (extending from the head to the neck), which is more effective and safe. In addition, different massage heads use different massage functions, which can also allow users to use a massager to obtain different massage methods. The coordinated use of multiple different massage methods corresponding to different parts can also obtain better massage effects and enhance the user experience.

[0134] It can be understood that since the middle massage head 12 is a heating massage head, it is located between the first massage head 21 and the second massage head 22 of the pulse massage head. If the middle massage head 12 touches the first massage head 21 or the second massage head 22 during wearing, it will not cause a short circuit, effectively ensuring the normal operation and use of the cervical massager 200.

[0135] The cervical massager 200 disclosed in the second embodiment of the present invention is further provided with a first massage head 21 and a second massage head 22 which are respectively located on both sides of the middle massage head 12. The first massage head 21 and the second massage head 22 are pulse massage heads respectively, and the middle massage head 12 is a heating massage head. Thus, one instrument can not only massage different neck positions of the user respectively, but also realize different massage functions, thereby meeting the different usage requirements of the user and improving the user experience.

[0136] The cervical massager disclosed in the embodiment of the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the cervical massager of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
