The technical solution of the present application will be further described with reference to the following embodiments and accompanying drawings.

The embodiment of the application discloses a massage head, which is used for being installed on a massage instrument with a host machine so as to massage the part to be massaged of a user. The massage apparatus with the main machine may be, for example, a neck massage apparatus, a shoulder massage apparatus, a waist massage apparatus, a leg massage apparatus, or the like.

Referring to fig. 1 to 6, a massage head 100 according to an embodiment of the present application is shown, including:

the mounting seat 1 is a flexible mounting seat, namely the mounting seat 1 is made of flexible materials, the mounting seat 1 is provided with an annular groove 11, and an electronic component (not shown) is arranged in the mounting seat 1 and is positioned on the inner side of the annular groove 11;

metal electrode slice 2, metal electrode slice include working face 21 and the back 22 that sets up back to back, and working face 21 is for keeping away from the one side of ring channel 11, and back 22 is the one side towards ring channel 11, has annular grafting portion 23 on the back 22 (the back has annular grafting portion 23 up in fig. 4 promptly), and annular grafting portion 23 is fixed to be inserted and is established in ring channel 11, makes ring channel 11 parcel annular grafting portion 23.

In the embodiment of the application, the mounting seat 1 itself is made of a flexible material, the mounting seat 1 is recessed towards the inside of the mounting seat 1 (that is, the mounting seat 1 is recessed upwards in fig. 3) to form the annular insertion portion 11, the back surface 22 of the metal electrode plate 2 is provided with the annular insertion portion 23, and the annular insertion portion 23 is matched with the annular insertion portion 11 in a fixed insertion manner, so that the annular insertion portion 23 is wrapped around the periphery of the annular insertion portion 11 by the annular insertion portion 11 made of the flexible material. So set up, because the ring channel 11 is flexible material, when utilizing ring channel 11 parcel metal electrode slice 2's annular grafting portion 23, can effectively reduce the clearance between ring channel 11 and the annular grafting portion 23 to because of the parcel setting of ring channel 11, and messenger massage head 100 has good waterproof sealing performance. The sealing performance can well prevent liquid from permeating into the mounting seat, and for the electronic elements which are arranged in the mounting seat 1 and positioned at the inner side of the annular groove 11, the electronic elements can be prevented from being short-circuited and failed due to the liquid permeation, and the service life of the massage head can be prolonged.

It should be noted that, in the embodiment of the present application, the flexible material refers to a material that is relatively flexible and has a certain structural strength and can be used as a base structure, for example, a material such as silicone rubber, and TPE, where the TPE is a Thermoplastic Elastomer (TPE). Particularly in the present embodiment, a silicone seat may be preferably used as the mounting seat.

The electronic components in the mounting base 1 may be one or more of EMS electrical connecting wires, heating elements or thermosensitive components, and these electronic components are used in cooperation with the metal electrode plates, so that the metal electrode plates can realize the massage functions of EMS (electrical Muscle Stimulation) massage, hot compress and the like. Specifically, when the electronic element comprises an EMS electric connecting wire, at least one part of the EMS electric connecting wire is positioned at the inner side of the annular groove and is welded with the metal electrode plate 2, the metal electrode plate 2 can provide EMS (electrical muscle stimulation) massage, and pulse current is applied to the part to be massaged, so that the blood circulation of the muscle of the part to be massaged is accelerated, and the muscle is effectively relieved.

As an alternative embodiment, the annular insertion part 23 may be fixedly inserted into the annular groove 11 by various fixing connection methods. For example, after the annular insertion portion is inserted into the annular groove, the fixed connection relationship between the annular insertion portion and the annular groove may be further fixed by additionally arranging a stud and nut fit or a snap fit of a snap fastener between the annular insertion portion and the annular groove. In particular in the present embodiment, the annular plug part is preferably fixed and glued by gluing. The annular insertion part 23 is fixedly bonded in the annular groove 11 in an adhesive manner, so that on one hand, the sealing and waterproof effects between the annular insertion part 23 and the annular groove 11 can be enhanced, and the wrapping effect of the annular groove 11 on the annular insertion part 23 is enhanced; on the other hand, the installation relation between the metal electrode plate 2 and the installation seat 1 is more stable and firm, the gluing and fixing operation difficulty is low, and the assembly operation between the metal electrode plate 2 and the installation seat 1 is facilitated to be simplified under the condition that other fixing structures are not required to be introduced.

Referring to fig. 3 and 4, in the embodiment of the present application, the annular groove 11 is disposed at the periphery of the mounting seat 1, and the annular insertion portion 23 is located inside the back surface 22 of the metal electrode sheet 2 and extends from an edge close to the back surface 22 toward the mounting seat 1. As another alternative, the annular insertion portion may also be a flange provided in the direction of the metal electrode plate toward the annular groove.

By adopting the structure, the annular groove 11 is arranged on the periphery of the mounting seat 1 as much as possible, correspondingly, the annular insertion part 23 is also arranged on the edge or the vicinity of the edge of the metal electrode plate 2 as much as possible, so that when the annular insertion part 23 is inserted and assembled with the annular groove 11, the whole structure is more stable.

In addition, when the annular insertion-connection part 23 is configured as shown in fig. 4, and the annular insertion-connection part 23 is disposed on the inner side of the back surface 2 and is disposed close to the edge of the metal electrode plate 2, a circle of outer frame 24 is further formed between the annular insertion-connection part 23 and the edge of the metal electrode plate 2. When the annular insertion portion 23 is fixedly inserted into the annular groove 11, as shown in fig. 1 and 2, the ring of outer rim 24 forms a blocking rim for preventing liquid from penetrating into the annular groove 11, thereby further enhancing the waterproof effect of the massage head 100. Specifically, when liquid is applied to the metal electrode plate 2, the liquid does not directly contact the annular groove 11, but flows through the outer frame 24 and then flows into the annular groove 11, and the liquid flows through the annular groove 11 more difficultly after being blocked by the outer frame 23, so that the waterproof effect of the massage head is enhanced. Especially when the outer frame 24 is adhesively fixed to the mounting base 1, it is more difficult for liquid to penetrate from the outer frame 24 into the annular groove 11.

When the annular insertion part is a flanging of the metal electrode plate, the flanging is wrapped in the annular groove formed by the flexible material. Because the flanging in the metal electrode plate is possibly sharp-edged, the flanging is wrapped in the flexible annular groove, namely the sharp edge is wrapped, so that the risk that the sharp edge scratches the body part of a user can be avoided.

Furthermore, the metal electrode plate also comprises a transition part connected between the flanging and the working surface of the metal electrode plate, and the transition part is used for transiting the working surfaces of the flanging and the metal electrode plate, so that the risk of scratching the body parts of a user due to the sharp structure part of the metal electrode plate can be further reduced. As some optional embodiments, the outer surface of the transition portion may be provided with a cambered surface or an inclined surface, so as to achieve a better protection effect and avoid scratching a user. In addition, through the setting with turn-ups parcel in the ring channel, still make the edge of metal electrode piece be located the inboard of mount pad, also be less than the edge of mount pad in the edge of metal electrode piece, the user uses massage head in-process like this, when contacting the mount pad that is located the outside, massage seats such as silica gel seat are because of having soft characteristics of texture, so the user contacts the mount pad and also can not produce and press against hard the sense, can improve the user and use the comfort of massage head.

As other alternative embodiments, the annular groove may not be disposed on the periphery of the mounting seat, but rather may be disposed closer to the center of the mounting seat, and similarly, the annular insertion portion may also be disposed closer to the center of the metal electrode sheet, and still achieve the insertion fit between the annular insertion portion and the annular groove.

Referring to fig. 5 and 6, in order to further improve the stability of the assembly relationship between the metal electrode plate and the mounting seat, in the embodiment of the present application, the annular groove 11 is configured as an inclined groove, the bottom of the annular groove 11 is disposed near the central axis of the mounting seat 1, and the notch of the annular groove 11 is disposed far away from the central axis of the mounting seat 1. The central axis of the mounting seat 1 is an axis located in the middle of the mounting seat 1 and perpendicular to the mounting surface of the mounting seat 1, that is, an axis located in the middle of the mounting seat 1 in fig. 5 and extending in an approximately oblique up-down direction. By adopting the chute, namely, the inclined direction of the annular groove 11 is gradually contracted inwards from the notch to the groove bottom, the chute design is favorable for increasing the fixed connection area between the annular insertion part 23 and the annular groove 11 on one hand, and particularly is favorable for increasing the bonding area between the annular insertion part 23 and the annular groove 11 when the annular insertion part 23 and the annular groove 11 are fixedly bonded by adhesion, so that the bonding and the fixation of the annular insertion part 23 and the annular groove are firmer, and the assembly relation between the metal electrode plate 2 and the mounting seat 1 is more stable; on the other hand, the annular insertion part 23 of the metal electrode plate 2 can be inserted into the annular groove 11 in an interference manner, and a joint surface which is inclined inwards gradually is formed between the annular insertion part and the annular groove, which is also beneficial to improving the stability of the connection relationship between the annular insertion part and the annular groove.

As some optional embodiments, the shape of the annular groove in the embodiment of the present application may be set such that the sectional shape of the annular groove in the axial direction is substantially rectangular as shown in fig. 5 and 6; the cross section of the annular groove along the axial direction is in a wave shape of the inner groove wall and the outer groove wall, correspondingly, the annular insertion part of the metal electrode plate is also in a wave shape, the annular insertion part can be smoothly inserted into the annular groove by adopting the shape, and the contact area between the annular insertion part and the annular groove is larger by adopting the shape, so that the stability and the firmness of the assembly connection between the annular insertion part and the annular groove are better facilitated.

It should be noted that, in the embodiment of the present application, the axis of the mounting seat refers to an axis perpendicular to the mounting surface of the mounting seat, the central axis of the mounting seat is an axis located in the middle of the mounting seat, and the mounting surface of the mounting seat is a surface provided with an annular groove, that is, a surface of the mounting seat in the radial direction.

Referring back to fig. 3, the mounting base 1 has a certain thickness L along the axis direction thereof, and L is greater than or equal to 3mm and less than or equal to 7 mm. In the embodiment of the present application, the thickness of the mount 1 in the axial direction is also the thickness of the mount 1 in the vertical direction in fig. N. In the thickness range, the mounting seat 1 made of flexible materials can keep a certain structural shape, has certain structural strength and can play a role in structural support of the metal electrode plate. If the thickness L is less than 3mm, the mounting seat 1 is easily torn; if the thickness L is more than 3mm, on one hand, the production cost is increased, and on the other hand, the flexible deformation amount of the mounting seat per se is weakened, and the adjustment capability of the mounting seat on massage vibration is reduced when the mounting seat is used for massage. As an alternative embodiment, the thickness L may be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm or 7 mm.

In the embodiment of the application, the working surface of the metal electrode plate 2 is flush with the end surface of the annular groove 11; or the working surface of the metal electrode plate 2 protrudes out of the end surface of the annular groove 11, and the protruding height range is 0.3mm-2.5 mm. The working surface of the metal electrode plate 2 is set to be not lower than the end surface of the annular groove 11, so that when a user uses the massage head 100, the part of the body to be massaged can effectively contact with the metal electrode plate 2 and be attached to the metal electrode plate 2. The embodiment of the application preferably adopts a mode that the working surface of the metal electrode plate 2 protrudes out of the end surface of the annular groove 11, so that the protruding height is in the range of 0.3mm-2.5 mm. If the projection height range is greater than 2.5mm, the large projection height may affect the assembling effect between the metal electrode tab 2 and the internal structure of the mount 1 in consideration of the limited thickness of the metal electrode tab 2. As an alternative embodiment, the height of the protrusion may be 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 1.8mm, 2.0mm, 2.3mm or 2.5 mm.

In the embodiment of the present application, the outer surface of the mounting base 1 close to the metal electrode sheet 2 is set to be in a rounded shape, please refer to fig. 6, the outer surface of the mounting base 1 close to the metal electrode sheet 2 also corresponds to the outer groove 111 of the annular groove 11, so that the outer surface of the mounting base 1 is smoother and smoother, and has no sharp edges, so that when the part of the user to be massaged contacts the mounting base, the touch feeling is better, and no hard feeling is generated.

Referring to fig. 3 to 8, in order to further improve the assembly stability between the metal electrode plate and the mounting seat, a boss 12 protruding toward the metal electrode plate 2 (i.e., the mounting seat 1 protrudes outward from the paper surface in fig. 8) is formed inside the mounting seat 1, the boss 12 is abutted against and adhesively fixed to the back surface 22 of the metal electrode plate 2, and the outer side wall of the boss 12 is formed as the inner side groove wall of the annular groove 11. In the embodiment of the present application, the boss 12 abuts against the back surface 22 of the metal electrode plate 2 and is bonded and fixed, so that the bonding area between the metal electrode plate 2 and the mounting seat 1 can be further increased, and the improvement of the stability of the fixed connection between the metal electrode plate 2 and the mounting seat 1 is facilitated. Especially, the outer side wall of the boss 12 forms the inner side groove wall of the annular groove 11, that is to say, the boss 12 is arranged adjacent to the annular groove 11, so that the annular insertion part is fixedly inserted into the annular groove, the back surface of the metal electrode plate is abutted and adhered to the surface of the boss, the assembly stability between the metal electrode plate and the mounting seat can be improved under the combined action, and especially, when the annular insertion part is also fixed to the annular groove through glue, the assembly between the metal electrode plate and the annular groove is convenient, and the assembly stability of the metal electrode plate and the annular groove can be ensured.

In the embodiment of the application, in the radial direction of the mounting seat 1, the width of the boss 12 in the radial direction of the mounting seat 1 is D, D is greater than or equal to 1mm and less than or equal to 3mm, and the width is maintained, so that the boss 12 can provide sufficient support strength for the annular insertion part 23. If D is smaller than 1mm, the width of the boss 12 in the radial direction is too small, the structural strength of the boss is not enough to form powerful support for the annular insertion part 23, and the metal electrode plate 2 is easy to loosen and separate from the annular groove 11; if D is larger than 3mm, it is not favorable to hollowing out the avoidance space capable of accommodating other structures in the middle of the boss 12. As an alternative embodiment, the width D of the boss 12 in the radial direction of the mount 1 may be 1mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm or 3 mm.

In the embodiment of the present application, the surface of the annular insertion part 23 and the annular groove 11, or the surface of the metal electrode plate 2 and the boss 12, which are oppositely arranged, are fixedly connected by gluing, so that the metal electrode plate 2 and the mounting seat 1 are conveniently and stably assembled. However, the use of adhesive fixation means that an excessive amount of adhesive is used at the position to be bonded, and for example, the annular insertion part 23 and the annular groove 11 are fixed by adhesive, an excessive amount of adhesive needs to be coated at the annular groove 11, so as to ensure a good bonding effect between the annular insertion part 23 and the annular groove 11. The bonding of the metal electrode sheet 2 to the opposite surface of the boss 12 also requires the application of an excessive amount of adhesive. In order to avoid the problems of uneven thickness of the adhesive on the bonding surface, uneven surface of the metal electrode plate after being attached and the like caused by the non-local accommodation of the excessive glue, the embodiment of the application also provides an adhesive overflowing structure, and provides a certain extrusion release space for the excessive adhesive.

As an alternative embodiment, referring to fig. 9, an inner groove wall 112 of the annular groove 11 protrudes outward along a radial direction of the mounting seat 1 to form a step body 41, and when the annular insertion portion 23 is fixedly inserted into the annular groove 11 by gluing, the step body 41 is used to provide a containing space for excess adhesive. In this application embodiment, form this step body 41 in the notch department of installation tank wagon 11, owing to provide more accommodation spaces on the basis of ring channel 11, so metal electrode piece 2 bonds when in ring channel 11, and excessive gluing agent can be extruded this step body 41 on, makes step body 41 provide certain excessive glue accommodation space, prevents from scribbling inhomogeneous problem after the unevenness that leads to the electrode piece laminating because of glue thickness from this, reduces assembly error.

In addition, the step body 41 can also serve as a guide for mounting the metal electrode sheet 2. The root of the inner side surface of the annular insertion part 23 is arranged in an arc shape with a round angle, so that when the boss 12 is required to be arranged in the mounting seat 1, four corner parts of the boss 12 are required to be arranged into the round angles matched with the annular insertion part 23, otherwise, the assembly of the metal electrode plate 2 in the annular groove 11 is difficult. However, the step body 41 is formed on the inner groove wall 112 of the annular groove 11, that is, the step body 41 is formed on the outer wall surface of the boss 12, and due to the arrangement of the step body 41, a certain distance is provided between the metal electrode plate 2 and the boss 12, and at this time, no matter four corners of the boss 12 are arranged to be round corners or right angles, no interference is generated on the assembly of the metal electrode plate 2 in the annular groove 11, so that the structural design requirement on the boss 12 can be reduced, and the assembly error of the metal electrode plate 2 can also be reduced.

As another alternative, the boss may also be recessed inward to form an overflow groove (not shown); when the annular insertion part is fixedly inserted into the annular groove through gluing, the glue overflowing groove is used for providing a containing space for excessive glue. This application embodiment, through set up special excessive gluey groove on the boss, can insert to the ring channel in annular insertion part, when the relative surface of metal electrode piece and boss bonds, spill over excessive gluing agent from the ring channel to excessive gluey groove and carry out the holding. Because overflow gluey groove can provide the extrusion release space of reserving for excessive gluing agent, so can prevent to paint the uneven problem of surface after the inhomogeneous results in the metal electrode piece laminating because of gluing agent thickness, and then reduce assembly error. In addition, the setting overflow gluey groove can also avoid the direct overflow of excessive gluing agent to the inside condition of mount pad to appear.

Furthermore, the glue overflowing groove is arranged close to the annular groove, so that excessive glue from the annular groove can overflow into the glue overflowing groove more conveniently. In the assembly connection of the metal electrode plate and the mounting seat, the annular insertion part and the annular groove are particularly important in bonding and fixing, so that more adhesive is arranged at the joint of the metal electrode plate and the mounting seat, the adhesive overflowing groove is arranged close to the annular groove, and the adhesive overflowing groove is favorable for quickly collecting the redundant adhesive overflowing from the annular groove.

In order to simultaneously take account of the glue overflowing effect and the structural strength between the mounting seat and the metal electrode plate, the groove body depth of the glue overflowing groove is smaller than or equal to that of the annular groove, and meanwhile, the groove body depth of the glue overflowing groove is smaller than or equal to 3 mm. If the groove body depth of the glue overflow groove is too deep, for example, the groove body depth is greater than that of the annular groove or is greater than 3mm, the boss is easily hollowed, the structural strength of one side of the boss close to the metal electrode plate is weakened, and sufficient supporting force can not be provided for the annular insertion part. In some alternative embodiments, the groove body depth of the glue overflow groove can be 3mm, 2.8mm, 2.5mm, 2.2mm, 2mm, 1.5mm, 1mm or 0.8 mm.

As another alternative, the two glue overflowing structures can be arranged at the same time, so as to provide more extrusion releasing space for the excessive glue. That is, in the embodiment of the present application, a step body is formed by protruding outward from the inner groove wall of the annular groove along the radial direction of the mounting seat, and the extra step space is used to provide the glue overflow space; the lug boss is inwards concave to form a glue overflow groove, and a groove body of the glue overflow groove is used for providing a glue overflow space.

In order to make the massage head 100 have more functions, the massage head 100 further includes a heating element 3, the heating element 3 is fixedly disposed on the back 22 of the metal electrode plate 2 (i.e. the heating element 3 is fixedly disposed on the upper surface of the metal electrode plate 3 in fig. 4), the boss 12 is recessed toward itself (i.e. the boss 12 is recessed toward the inner side of the paper surface in fig. 3) to form a space for avoiding, the heating element 3 is accommodated in the space for avoiding, and the flexible material of the mounting base 1 for forming the space for avoiding adopts a poor thermal conductor material.

In this application embodiment, through set firmly heating member 3 on metal electrode piece 2, can utilize heating member 3 to heat metal electrode piece 2, promote the massage effect. In addition, in order to improve the heating efficiency, a clearance space is formed on the boss 12 corresponding to the position where the heating element 3 is arranged, when the surface of the metal electrode plate 2 is abutted against and adhered to the surface of the boss 12, the surface of the metal electrode plate 2 abutted against the boss 12 and the clearance space together enclose to form a closed or non-closed cavity, and when the heating element 3 is accommodated in the cavity, the heat emitted by the heating element can be transmitted in a concentrated manner through the cavity. Especially, the flexible material of the mounting seat for forming the avoiding space in the embodiment of the present application adopts a thermal poor conductor material, for example, the mounting seat is a silica gel seat, and silica gel is a thermal poor conductor, so that the heat loss of the heat of the heating member 3 exchanging heat with the avoiding space is small, and more heat of the heating member 3 is transferred to the metal electrode plate 2, thereby improving the heat transfer efficiency.

The heating element 3 may be fixed on the back surface 22 of the metal electrode sheet 2, or may be mounted in other manners. For example, the heating element 3 may not be fixedly disposed on the back 22 of the metal electrode plate 2, but may be fixedly disposed on the sidewall or the bottom wall of the space, or the heating element 3 may be merely accommodated in the space, and is not fixedly connected to the back 22 of the metal electrode plate 2, nor fixedly connected to the structure of the space, so that the heating element 3 can transfer heat to the metal electrode plate 2 during heating operation as long as the heating element 3 is accommodated in the space, and thus the fixed mounting of the heating element 3 is not limited.

In the embodiment of the present application, the heating element 3 is specifically a heating wire 31 fixedly arranged on the metal electrode plate 2, the avoiding space is an accommodating groove 13 formed by an inner concave of the boss, and the heating wire 31 is accommodated in the accommodating groove 13. When the surface of the metal electrode plate 2 is abutted to and bonded with the surface of the boss 12, the surface of the metal electrode plate 2 abutted to the boss 12 and the accommodating groove 13 jointly enclose to form a closed cavity, and when the heating element 3 is accommodated in the cavity, the heat emitted by the heating element can be transmitted in a concentrated manner through the cavity. Especially, the mount pad is the silica gel seat, and holding tank 13 is the silica gel holding tank, and this silica gel holding tank heat conductivility is bad, so make the calorific loss that heater 31 sent less, can transmit to metal electrode slice 2 more concentratedly.

Referring to fig. 8, the mounting base 1 is provided with a wire passing hole 14 along the axis direction thereof, and an avoiding notch 15 communicated with the wire passing hole 14 is formed in the accommodating groove 13; the heating wire 31 includes a heating portion 311 and an electrical connection wire 312 connected to the heating portion 311, the connection ends of the heating portion 311, the heating portion 311 and the electrical connection wire 312 are accommodated in the accommodating groove 13, and the electrical connection wire 312 is inserted into the avoiding notch 15 and the wire passing hole 14. In the embodiment of the application, the wire passing hole 14 and the avoiding notch 15 are arranged to facilitate the routing of the heating wire 31, so as to realize the electrical connection between the heating wire 31 and an external structure. Meanwhile, in order to avoid the influence on the abutting joint setting effect between the metal electrode plate 2 and the boss 12 due to the unreasonable arrangement of the wiring space of the heating wire 31, specifically, an avoiding notch 15 is arranged in the accommodating groove 13, the middle part of the mounting seat is provided with the wire passing hole 14, and meanwhile, the heating part 311 of the heating wire and the connecting end of the electric connecting wire 312 are arranged in the accommodating groove 13, the structure is arranged, the avoiding space is reserved for all wiring, so that the electric connecting wire 312 and an external structure are electrically connected and wired, and the abutting joint between the metal electrode plate 2 and the boss 12 can be kept to have good flatness.

Specifically, referring to fig. 4 and 8, the massage head 100 is configured to be installed on a massage apparatus (not shown) with a host, the avoiding notch 15 includes a first avoiding notch 15a and a second avoiding notch 15b respectively communicated with the wire through hole 14, the electrical connection wire 312 includes a first electrical connection wire 312a and a second electrical connection wire 312b respectively disposed at two ends of the heat generating portion 311, the first electrical connection wire 312a is disposed in the first avoiding notch 15a and the wire through hole 14, the second electrical connection wire 312b is disposed in the second avoiding notch 15b and the wire through hole 14, and the first electrical connection wire 312a and the second electrical connection wire 312b are electrically connected to the host respectively. Two first avoidance gaps 15a and two second avoidance gaps 15b which are independent of each other are arranged on the inner wall of the accommodating groove 13, and can be used for enabling the first electric connection wire 312a and the second electric connection wire 312b of the heating wire 31 to respectively pass through and not to be in contact with each other, so that the two electric connection wires are prevented from being in contact short circuit.

In the embodiment of the present application, the heating wire 31 may be set as a round of surrounding heating wire, or may be set as a promised circle of surrounding heating wire, which may all have a good heating function, and especially has a better heating effect when set as a plurality of circles of surrounding heating wire. Further, the heating wire 31 is preferably provided near the edge of the metal electrode sheet 2. In fact, as long as the heating wire 31 is fixed on the metal electrode plate 2, the heat can be transferred to the metal electrode plate 2, but the closer the heating wire 31 is to the edge of the metal electrode plate 2, the longer the total length of the heating wire is, and the faster the heating rate of the heating wire and the faster the temperature rise speed of the metal electrode plate can be.

Referring to fig. 8, the receiving groove 13 divides the boss 12 into a first boss 121 and a second boss 122, the first boss 121 is an outer boss close to the annular groove 11, the second boss 122 is an inner boss far from the annular groove 11, and the second boss 122 is located inside the first boss 121. In the radial direction of the mounting seat 1, the width of the first boss 121 along the radial direction of the mounting seat 1 is D, and D is greater than or equal to 1mm and less than or equal to 3 mm. If D is smaller than 1mm, the width of the first lug boss in the radial direction is too small, the structural strength of the first lug boss is not enough to form powerful support for the annular insertion part 23, and the metal electrode plate 2 is easy to loosen and separate from the annular groove 11; if D is greater than 3mm, first boss is too big in radial ascending width, and this can lead to the holding tank 13 that is used for holding heater 31 to set up only more near the center of mount pad 1, and then leads to the length undersize that heater 13 can set up, influences the rate of heating of heater 13 and the rate of heating up of metal electrode slice 2, finally leads to massage head 100's hot compress function obvious time delay problem to appear. As an alternative embodiment, the width D of the first boss 121 in the radial direction of the mount 1 may be 1mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm, or 3 mm.

Referring to fig. 10 to 15, another massage head according to an embodiment of the present application is disclosed, in which the massage head 100 includes:

metal electrode slice 2, metal electrode slice include working face 21 and the back 22 that sets up back to back, and working face 21 is for keeping away from the one side of ring channel 11, and back 22 is the one side towards ring channel 11, has annular grafting portion 23 on the back 22 (the back has annular grafting portion 23 up in fig. 13 promptly), and annular grafting portion 23 is fixed to be inserted and is established in ring channel 11, makes ring channel 11 parcel annular grafting portion 23.

In the embodiment of the present application, the mounting base 1 itself is made of a flexible material, the mounting base 1 is formed with the annular insertion portion 11 toward the inner recess of the mounting base 1 (i.e., the mounting base 1 is recessed toward the direction in the paper surface in fig. 12), the back surface 22 of the metal electrode sheet 2 is provided with the annular insertion portion 23, and the annular insertion portion 23 is in fixed insertion fit with the annular insertion portion 11, so that the annular insertion portion 23 is wrapped around the periphery of the annular insertion portion 11 by the annular groove 11 made of the flexible material. So set up, because the ring channel 11 is flexible material, when utilizing ring channel 11 parcel metal electrode slice 2's annular grafting portion 23, can effectively reduce the clearance between ring channel 11 and the annular grafting portion 23 to because of the parcel setting of ring channel 11, and messenger massage head 100 has good waterproof sealing performance. The sealing performance can well prevent liquid from permeating into the mounting seat, and for the electronic elements which are arranged in the mounting seat 1 and positioned at the inner side of the annular groove 11, the electronic elements can be prevented from being short-circuited and failed due to the liquid permeation, and the service life of the massage head can be prolonged.

It should be noted that, in the embodiment of the present application, the flexible material refers to a material that is relatively flexible and has a certain structural strength, and can be used as a base structure, for example, a material such as silicone rubber, and TPE, where the TPE is a Thermoplastic Elastomer (TPE). Particularly in the present embodiment, a silicone seat may be preferably used as the mounting seat.

The electronic components in the mounting base 1 may be one or more of EMS electrical connecting wires, heating elements and thermosensitive components, and these electronic components are used in cooperation with the metal electrode plates, so that the metal electrode plates can realize the massage functions of EMS (electrical Muscle Stimulation) massage, hot compress and the like. Specifically, when the electronic element comprises an EMS electric connecting wire, at least one part of the EMS electric connecting wire is positioned at the inner side of the annular groove and is welded with the metal electrode plate 2, the metal electrode plate 2 can provide EMS (electrical muscle stimulation) massage, and pulse current is applied to the part to be massaged, so that the blood circulation of the muscle of the part to be massaged is accelerated, and the muscle is effectively relieved.

Referring to fig. 10 and 11, in the embodiment of the present application, the annular groove 11 is disposed on the periphery of the mounting seat 1, the annular insertion portion 23 is formed by extending upward from the edge of the back surface 22 of the metal electrode plate 2 toward the mounting seat 1, and the annular insertion portion 23 is a flange of the metal electrode plate 2. As other alternative embodiments, the annular insertion portion may also be located inside the rear surface and formed to extend from an edge near the rear surface toward the mounting seat.

In addition, when the annular insertion part 23 is configured as shown in fig. 11, the annular insertion part 23 is a flanged edge of the metal electrode plate 2, and the flanged edge is wrapped in the annular groove 11 made of the flexible material. Because the flanging in the metal electrode plate is possibly sharp-edged, the flanging is wrapped in the flexible annular groove 11, namely the sharp edge is wrapped, so that the risk that the sharp edge scratches the body part of a user can be avoided.

Further, the metal electrode plate 2 further comprises a transition part 25 connected between the flanging and the working surface 21 of the metal electrode plate, the transition part 25 is used for transitioning the working surface 21 of the flanging and the metal electrode plate, and the risk of scratching the body part of a user due to the sharp structure part of the metal electrode plate 2 can be further reduced. As some optional embodiments, the outer surface of the transition portion 25 may be provided with a cambered surface or an inclined surface to achieve a better protection effect and avoid scratching a user. In addition, through the setting with turn-ups parcel in the ring channel, still make the edge of metal electrode piece be located the inboard of mount pad, also be less than the edge of mount pad in the edge of metal electrode piece, the user uses massage head in-process like this, when contacting the mount pad that is located the outside, massage seats such as silica gel seat are because of having soft characteristics of texture, so the user contacts the mount pad and also can not produce and press against hard the sense, can improve the user and use the comfort of massage head.

When the annular insertion part is arranged on the inner side of the metal electrode plate but close to the edge of the metal electrode plate, a circle of outer frame is formed between the annular insertion part and the edge of the metal electrode plate. When the annular insertion part is fixedly inserted into the annular groove, the circle of outer frame can form a blocking frame for preventing liquid from permeating into the annular groove, so that the waterproof effect of the massage head is further enhanced. Specifically, when liquid is smeared on the metal electrode plate, the liquid cannot directly contact the annular groove, but flows through the outer frame and then flows to the annular groove, and the liquid flows through the annular groove difficultly after being blocked by the outer frame, so that the waterproof effect of the massage head is enhanced. Especially, when the outer frame is fixedly adhered to the mounting seat by gluing, liquid is more difficult to penetrate into the annular groove from the outer frame.

Referring to fig. 14 and 15, in order to further improve the stability of the assembly relationship between the metal electrode plate and the mounting seat, in the embodiment of the present application, the annular groove 11 is configured as an inclined groove, the bottom of the annular groove 11 is disposed close to the central axis of the mounting seat 1, and the notch of the annular groove 11 is disposed away from the central axis of the mounting seat 1. The central axis of the mounting base 1 is an axis located in the middle of the mounting base 1 and perpendicular to the mounting surface of the mounting base 1, that is, an axis located in the middle of the mounting base 1 and extending in an approximately oblique up-down direction in fig. 14. By adopting the chute, namely, the inclined direction of the annular groove 11 is gradually contracted inwards from the notch to the groove bottom, the chute design is favorable for increasing the fixed connection area between the annular insertion part 23 and the annular groove 11 on one hand, and particularly is favorable for increasing the bonding area between the annular insertion part 23 and the annular groove 11 when the annular insertion part 23 and the annular groove 11 are fixedly bonded by adhesion, so that the bonding and the fixation of the annular insertion part 23 and the annular groove are firmer, and the assembly relation between the metal electrode plate 2 and the mounting seat 1 is more stable; on the other hand, the annular insertion part 23 of the metal electrode plate 2 can be inserted into the annular groove 11 in an interference manner, and a joint surface which is inclined inwards gradually is formed between the annular insertion part and the annular groove, which is also beneficial to improving the stability of the connection relationship between the annular insertion part and the annular groove.

As some optional embodiments, the shape of the annular groove in the embodiment of the present application may be set such that the sectional shape of the annular groove in the axial direction is substantially rectangular as shown in fig. 14 and 15; the cross section of the annular groove along the axial direction is in a wave shape, correspondingly, the annular insertion part of the metal electrode plate is also in a wave shape, the annular insertion part can be smoothly inserted into the annular groove by adopting the shape, and the contact area between the annular insertion part and the annular groove is larger by adopting the shape, so that the stability and the firmness of the assembly connection between the annular insertion part and the annular groove are better facilitated.

Referring back to fig. 12, the mounting base 1 has a certain thickness L along the axis direction thereof, and L is greater than or equal to 3mm and less than or equal to 7 mm. In the embodiment of the present application, the thickness of the mount 1 in the axial direction is also the thickness of the mount 1 in the vertical direction in fig. N. In the thickness range, the mounting seat 1 made of flexible materials can keep a certain structural shape, has certain structural strength and can play a role in structural support of the metal electrode plate. If the thickness L is less than 3mm, the mounting seat 1 is easily torn; if the thickness L is more than 3mm, on one hand, the production cost is increased, and on the other hand, the flexible deformation amount of the mounting seat per se is weakened, and the adjustment capability of the mounting seat on massage vibration is reduced when the mounting seat is used for massage. As an alternative embodiment, the thickness L may be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm or 7 mm.

In the embodiment of the present application, the outer surface of the mounting base 1 close to the metal electrode sheet 2 is set to be in a rounded shape, please refer to fig. 15, the outer surface of the mounting base 1 close to the metal electrode sheet 2 also corresponds to the outer groove 111 of the annular groove 11, so that the outer surface of the mounting base 1 can be smoother and more rounded, no edge exists, and when the part to be massaged of a user contacts the mounting base, the touch feeling is better, and no hard feeling is generated.

Referring back to fig. 12, in order to further improve the assembly stability between the metal electrode tab and the mounting seat, a boss 12 protruding toward the metal electrode tab 2 (i.e., the mounting seat 1 protrudes outward from the paper surface in fig. 12) is formed inside the mounting seat 1, the boss 12 is abutted against and adhesively fixed to the back surface 22 of the metal electrode tab 2, and the outer side wall of the boss 12 is formed as the inner side groove wall of the annular groove 11. In the embodiment of the present application, the boss 12 abuts against the back surface 22 of the metal electrode plate 2 and is bonded and fixed, so that the bonding area between the metal electrode plate 2 and the mounting seat 1 can be further increased, and the improvement of the stability of the fixed connection between the metal electrode plate 2 and the mounting seat 1 is facilitated. Especially, the outer side wall of the boss 12 forms the inner side groove wall of the annular groove 11, that is to say, the boss 12 is arranged adjacent to the annular groove 11, so that the annular insertion part is fixedly inserted into the annular groove, the back surface of the metal electrode plate is abutted and adhered to the surface of the boss, the assembly stability between the metal electrode plate and the mounting seat can be improved under the combined action, and especially, when the annular insertion part is also fixed to the annular groove through glue, the assembly between the metal electrode plate and the annular groove is convenient, and the assembly stability of the metal electrode plate and the annular groove can be ensured.

In the embodiment of the application, in the radial direction of the mounting seat 1, the width of the boss 12 in the radial direction of the mounting seat 1 is D, D is greater than or equal to 1mm and less than or equal to 3mm, and the width is maintained, so that the boss 12 can provide sufficient support strength for the annular insertion part 23. If D is smaller than 1mm, the width of the boss 12 in the radial direction is too small, the structural strength of the boss is not enough to form powerful support for the annular insertion part 23, and the metal electrode plate 2 is easy to loosen and separate from the annular groove 11; if D is larger than 3mm, it is not favorable to hollowing out the avoidance space capable of accommodating other structures in the middle of the boss 12. As an alternative embodiment, the width D of the first boss 121 in the radial direction of the mount 1 may be 1mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm, or 3 mm.

In the embodiment of the present application, the surface of the annular insertion part 23 and the annular groove 11, or the surface of the metal electrode plate 2 and the boss 12, which are oppositely arranged, are fixedly connected by gluing, so that the metal electrode plate 2 and the mounting seat 1 are conveniently and stably assembled. However, the use of adhesive fixation means that an excessive amount of adhesive is used at the position to be bonded, and for example, the annular insertion part 23 and the annular groove 11 are fixed by adhesive, an excessive amount of adhesive needs to be coated at the annular groove 11, so as to ensure a good bonding effect between the annular insertion part 23 and the annular groove 11. The bonding of the metal electrode sheet 2 to the opposite surface of the boss 12 also requires the application of an excessive amount of adhesive. In order to avoid the problem that the thickness of the adhesive on the bonding surface is uneven due to the non-local accommodation of excessive glue, the surface of the metal electrode plate is uneven after the metal electrode plate is attached, the embodiment of the application further provides an adhesive overflowing structure, and a certain extrusion release space is provided for the excessive glue.

As an alternative embodiment, please refer to fig. 12, the boss 12 may be recessed inward to form an adhesive overflow groove 42, and when the annular insertion portion 23 is fixedly inserted into the annular groove 11 by gluing, the adhesive overflow groove 42 is used to provide a receiving space for the excess adhesive. In the embodiment of the application, the special glue overflowing groove 42 is formed in the boss 12, so that when the annular insertion part 12 is inserted into the annular groove 11 and the opposite surfaces of the metal electrode plate 2 and the boss 12 are bonded, excessive glue overflows from the annular groove 11 to the second overflow groove 42 for accommodating. Because the second overflow launder 42 can provide the extrusion release space of reserving for excessive gluing agent, so can prevent to scribble inhomogeneous surface unevenness problem after leading to metal electrode slice 2 to laminate because of gluing agent thickness, and then reduce assembly error. In addition, the second overflow groove 42 can prevent the excessive adhesive from directly overflowing into the mounting base 1.

Further, the glue overflow groove 42 is disposed close to the annular groove 11, so that the excessive glue from the annular groove 11 can overflow into the glue overflow groove 42 more conveniently. In the assembly connection of the metal electrode plate 2 and the mounting seat 1, the bonding fixation of the annular insertion part 23 and the annular groove 11 is particularly important, so that the adhesive arranged at the joint of the metal electrode plate and the mounting seat is also delivered, and the adhesive overflow groove 42 is arranged close to the annular groove 11, so that the excessive adhesive overflowing from the annular groove 11 can be collected quickly.

In order to simultaneously take account of the glue overflow effect and the structural strength between the mounting seat 1 and the metal electrode plate 2, the groove body depth of the glue overflow groove 42 is less than or equal to that of the annular groove 11, and meanwhile, the groove body depth of the glue overflow groove 42 is less than or equal to 3 mm. If the groove body depth of the glue overflow groove 42 is too deep, for example, greater than the groove body depth of the annular groove 42 or greater than 3mm, the boss 12 is easily hollowed out more, and at this time, the structural strength of the side of the boss 12 close to the metal electrode plate 2 becomes weak, which may not provide sufficient supporting force for the annular insertion part 23. In some alternative embodiments, the groove body depth of the glue overflow groove 42 may be 3mm, 2.8mm, 2.5mm, 2.2mm, 2mm, 1.5mm, 1mm, or 0.8 mm.

As another alternative embodiment, an inner groove wall of the annular groove (i.e., an outer side wall of the boss) protrudes outward in a radial direction of the mounting seat to form a step body, and when the annular insertion portion is fixedly inserted into the annular groove by gluing, the step body is used for providing a containing space for excess adhesive. In this application embodiment, form this step body in the notch department of ring channel, owing to provide more accommodation spaces on the basis of ring channel, so when the metal electrode piece bonds in the ring channel, excessive gluing agent can be extruded on this step body, makes the step body provide certain excessive glue accommodation space, prevents from scribbling inhomogeneous problem that leads to unevenness behind the electrode piece laminating because of glue thickness from this, reduces assembly error.

In addition, the step body can also play a guiding role in the installation of the metal electrode plate. The root of its medial surface adopts the arc setting of fillet, and when this set up the boss in the mount pad, need also set into four bights of boss and annular grafting portion assorted fillet, otherwise the assembly of metal electrode piece in the ring channel can be more difficult. However, the step body is formed on the inner side groove wall of the annular groove, namely the step body is formed on the outer wall surface of the boss, a certain distance is reserved between the metal electrode plate and the boss due to the arrangement of the step body, no matter four corners of the boss are arranged to be round corners or right angles, interference on assembly of the metal electrode plate in the annular groove can not be caused, and therefore the structural design requirement on the boss can be lowered, and the assembly error of the metal electrode plate can also be reduced.

In order to make the massage head 100 have more functions, the massage head 100 further comprises a heating element 3, the heating element 3 is fixedly arranged on the back 22 of the metal electrode plate 2, the lug boss 12 is concave inwards (to form a clearance space, the heating element 3 is accommodated in the clearance space, and the flexible material of the mounting seat 1 for forming the clearance space is made of a hot poor conductor material.

In this application embodiment, through set firmly heating member 3 on metal electrode piece 2, can utilize heating member 3 to heat metal electrode piece 2, promote the massage effect. In addition, in order to improve the heating efficiency, a clearance space is formed on the boss 12 corresponding to the position where the heating element 3 is arranged, when the surface of the metal electrode plate 2 is abutted against and adhered to the surface of the boss 12, the surface of the metal electrode plate 2 abutted against the boss 12 and the clearance space together enclose to form a closed or non-closed cavity, and when the heating element 3 is accommodated in the cavity, the heat emitted by the heating element can be transmitted in a concentrated manner through the cavity. Especially, the flexible material of the mounting seat for forming the space is made of a poor thermal conductor material, for example, the mounting seat is a silica gel seat, and silica gel is a poor thermal conductor, so that the heat loss of the heat generating member 3 in heat exchange with the space is small, and more heat of the heat generating member 3 is transferred to the metal electrode plate 2, thereby improving the heat transfer efficiency.

Referring to fig. 11, in the embodiment of the present application, the heating element 3 is a heating film 32 fixedly attached to the metal electrode sheet 2, the avoiding space is a groove formed by recessing the boss 12, the heating film 32 is disposed in the groove, and the boss 12 is disposed around the heating film 32. The heating film 32 is preferably disposed in the middle of the metal electrode sheet 2, and heats the metal electrode sheet 2 in a heat transfer manner from the middle to the periphery. Since the heating film 32 has a larger heating surface area than the heating wire 31, the heating film 32 has a good heating effect when used for heating. When the surface of the metal electrode plate 2 is abutted against and adhered to the surface of the boss 12, the heat generating film 32 is equivalently arranged in a groove space formed by the inner recess of the boss 12, and the heat emitted by the heat generating film can be well and intensively transferred to the metal electrode plate 2. Especially, the mounting seat is a silica gel seat, the groove is a silica gel groove, and the silica gel groove has poor heat conduction performance, so that the heat loss generated by the heating film 32 is small, and more heat can be transmitted to the metal electrode plate 2 in a more concentrated manner.

Referring to fig. 16, the present embodiment further provides a neck massager, wherein the neck massager includes the massage head 100 shown in fig. 1 to 9, or the neck massager includes the massage head 100 shown in fig. 10 to 15.
