Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, with reference to the drawings, a massage unit 100 for a massage apparatus 1000 according to an embodiment of the first aspect of the present invention is described. It should be noted that the specific type of the massage apparatus 1000 applied to the massage unit 100 is not limited, and may be, for example, an eye massage apparatus, a neck massage apparatus, a waist massage apparatus, a handheld massage apparatus, and the like.

As shown in fig. 1, the massage apparatus 1000 includes a body 200 and at least one massage unit 100, and in conjunction with fig. 2 and 3, the massage unit 100 includes: the unit comprises a unit shell 1 and a vibration part 2, wherein the unit shell 1 is suitable for being connected with the machine body 200, the vibration part 2 is arranged in the unit shell 1 and comprises a vibration component 21, and therefore when the vibration component 21 works, the vibration massage can be carried out on the human body through the contact of the unit shell 1 and the human body. It should be noted that "connection" in "the unit case 1 is adapted to be connected to the machine body 200" is to be understood in a broad sense, and may be a separate member and assembled to be connected, or may be an integral member. For example, when being a separate piece and assembled to be connected, the unit case 1 is assembled to be connected with a corresponding portion of the body 200. For example, when the unit housing 1 is formed as a single piece, at least a portion of the unit housing and a corresponding portion of the machine body 200 may be formed as a single piece, and may be formed by injection molding of a single material, or by secondary injection molding, for example, as long as the two pieces are not detachable.

The body 200 has an electric pulse generating device therein, and with reference to fig. 3 and 4, the massage unit 100 further includes a conductive member 3, the unit housing 1 includes a conductive shell 11, the conductive member 3 is welded to the conductive shell 11 to form an electrical connection, the conductive member 3 is adapted to be electrically connected to the electric pulse generating device, so that the electric pulse generating device is electrically connected to the conductive shell 11 through the conductive member 3, and thus when the electric pulse generating device works, the electric pulse generating device can be electrically conducted to the human body through the conductive shell 11, so as to perform an electric stimulation massage on the human body. Accordingly, the electric pulse generating device having a large volume is installed in the body 200, not integrated in the massage unit 100, so that the volume of the massage unit 100 can be simply and effectively reduced, and a larger number of massage units 100 can be installed in the same installation area of the body 200, thereby improving a massage effect.

In short, the massage unit 100 according to the embodiment of the present invention at least has the dual functions of vibration massage and electrical stimulation massage, and has a rich function, and the electrical pulse generator is disposed in the body 200 and electrically connected to the conductive shell 11 through the conductive member 3, so that the volume of the massage unit 100 with more functions can be ensured to be smaller. It should be noted that the conductive shell 11 is not limited to be electrically conducted with the human body, for example, the conductive shell 11 may be directly contacted with the human body to realize direct electrical conduction between the conductive shell 11 and the human body, or a conductive layer, such as a conductive gel, may be disposed on the conductive shell 11, and the conductive shell 11 may be directly contacted with the human body through the conductive layer to realize indirect electrical conduction between the conductive shell 11 and the human body.

Referring to fig. 3 to 6, the conductive case 11 includes an end cover portion 111 and a side wall portion 112, the end cover portion 111 is located at the end of the unit case 1 facing away from the machine body 200, the side wall portion 112 is connected to the end cover portion 111, a side of the side wall portion 112 facing away from the end cover portion 111 defines a mounting opening 114, the vibration member 2 is adapted to be mounted into the conductive case 11 through the mounting opening 114, so that the vibration member 2 is located inside the side wall portion 112, that is, the side wall portion 112 is disposed around an outer circumferential surface of the vibration member 2, and the vibration member 2 is located in a space defined by the end cover portion 111 and the side wall portion 112. Thus, by providing the mounting opening 114 on the side of the side wall portion 112 away from the end cover portion 111, the vibration member 2 is adapted to be mounted into the conductive shell 11 through the mounting opening 114, so that the structure of the conductive shell 11 can be simplified and the mounting of the vibration member 2 can be facilitated.

As shown in fig. 6, the side wall part 112 includes an extension part extending to a side of the vibration member 2 facing away from the end cover part 111, at least a part of the extension part is bent inward relative to the side wall part 112 to form a bent part 113, and the bent portion 113 is used for stopping the vibration member 2 from passing over the bent portion 113 in a direction away from the end cover portion 111, that is, the bent portion 113 is bent toward the central axis 20 of the vibration member 2 with respect to the side wall portion 112, so as to be on the back side in the axial direction of the vibration member 2 and opposite to the vibration member 2 in the axial direction of the vibration member 2 (as the bent portion 113 is located at the region Z1 shown in fig. 7), therefore, when the vibration member 2 moves in the direction away from the end cover part 111, when the vibration member 2 contacts the bending part 113, the vibration member 2 is stopped by the bending part 113 and can not move in the direction away from the end cover part 111, so that the vibration member 2 can be prevented from coming out of the conductive shell 11 from the mounting opening 114 toward the direction away from the end cover part 111.

It can be understood that, since the bent portion 113 is bent inward, as long as the bent portion 113 is opposed to the vibration member 2 in the axial direction of the vibration member 2, the vibration member 2 can be stopped from passing over the bent portion 113 in the direction away from the end cap portion 111, and therefore, whether or not the bent portion 113 is in contact with the vibration member 2 is not required. For example, the bending portion 113 may not contact the vibration member 2, so that although the vibration member 2 moves a certain distance in a direction away from the end cap portion 111, the vibration member is stopped by the bending portion 113 after contacting the bending portion 113, so as to avoid the mounting opening 114 from coming out of the conductive shell 11. In addition, when the bending portion 113 is not in contact with the vibration member 2, the gap between the bending portion 113 and the vibration member 2 may be limited to 10mm or less, for example, 10mm, 9mm, 8mm, 7mm, 6mm, 5mm, 4mm, 3mm, 2mm, 1mm, and the like, so that the amount of movement activity of the vibration member 2 in the conductive case 11 may be reduced, and the mounting stability of the vibration member 2 may be improved to some extent.

For example, the bent portion 113 may be in contact with the vibration member 2, and at this time, the vibration member 2 is always stopped by the bent portion 113 and does not move in a direction away from the end cap portion 111, so that the mounting stability of the vibration member 2 can be improved. That is, the bending portion 113 after bending can also press and fix the vibration component 2, so that the vibration component 2 can be more firmly mounted, and the working reliability of the vibration component 2 is improved.

It is understood that, as shown in fig. 6 to 7, the side of the vibration member 2 facing the end cap section 111 is the axial front side (the region Z4 on the left side of the line Y3 and the line Y4 shown in fig. 7 is the axial front side), the side facing away from the end cap section 111 is the axial back side (the region Z1, the region Z2, and the region Z3 on the right side of the line Y1 and the line Y2 shown in fig. 7 are the axial back sides), and the side of the vibration member 2 facing the circumferential wall surface of the unit case 1 is the circumferential side (the region Z5 and the region Z6 between the line Y1-Y2 and the line Y3-Y4 shown in fig. 7 are the circumferential side). The "side of the vibration member 2 facing away from the end cap section 111" is to be understood in a broad sense, and the region Z1, the region Z2, and the region Z3 on the right side of the line Y1-Y2 shown in fig. 7 all belong to the side of the vibration member 2 facing away from the end cap section 111.

As shown in fig. 6, the conductive member 3 is located on the side of the vibrating member 2 facing away from the end cap portion 111, and the conductive member 3 is welded to the bent portion 113 to form a welding point 30, so that the electric pulse generating device is electrically connected to the conductive shell 11 through the conductive member 3. Thus, since the side wall portion 112 includes an extended portion extending to a side of the vibration member 2 facing away from the end cover portion 111, at least a portion of the extended portion is bent inward relative to the side wall portion 112 to form the bent portion 113 and is welded to the conductive member 3, thereby avoiding welding in a small space between the end cover portion 111 and the axial front side surface of the vibration member 2 and in a small space between the side wall portion 112 and the circumferential side surface of the vibration member 2, ensuring sufficient welding space, and facilitating the welding operation.

Or stated differently, it is possible to ensure that the space between the end cover portion 111 and the axial front side surface of the vibration member 2 is small and the space between the side wall portion 112 and the circumferential side surface of the vibration member 2 is small, thereby improving the structural compactness of the massage unit 100 and reducing the movement margin of the vibration member 2 within the unit case 1. Moreover, the end cap portion 111 and the axial positive side surface of the vibration component 2 can be prevented from jointly pressing the welding point 30, and the side wall portion 112 and the circumferential side surface of the vibration component 2 can be prevented from jointly pressing the welding point 30, so that the electrical connection stability of the welding point 30 can be ensured, the electrical connection reliability of the conductive shell 11 and the electric pulse generating device can be improved, and the effectiveness and reliability of the electric stimulation massage can be further ensured.

In addition, because the portion 113 of bending is bent at the axial dorsal part of vibrating part 2 and towards the direction that is close to the central axis 20 of vibrating part 2, thereby can have great space and weld, convenient welding operation, and welding point 30 can comparatively keep away from the lateral wall of unit shell 1, in the in-process of vibrating part 2 work, reduce the collision that the lateral wall of unit shell 1 caused to welding point 30, arouse that welding point 30 damages or electric connection is bad scheduling problem, and then can guarantee the electric connection stability of welding point 30, improve the electric connection reliability of electrically conductive shell 11 and electric pulse generating device, guarantee the validity and the reliability of electric stimulation massage. In addition, the shapes of the side wall portion 112 and the bending portion 113 can better adapt to the shape of the vibrating component 2, and the structure compactness of the conductive shell 11 is improved, so that the structure of the massage unit 100 is more compact and smaller.

Further, in some cases, since the welding point 30 does not occupy a small space between the end cover portion 111 and the axial direction positive side surface of the vibration member 2, it is possible to avoid an influence on the arrangement of other parts (such as the heat generating portion 40 hereinafter) in the small space. In addition, in some cases, since the welding points 30 do not occupy a small space between the side wall portion 112 and the circumferential side surface of the vibration member 2, it is possible to avoid affecting the assembly of the side wall portion 112 (e.g., the assembly of the conductive shell 11 and the connection shell 12 described later) or the assembly of the side wall portion 112 and the vibration member 2, and the like.

In short, the bent portion 113 can be used to limit the vibration component 2 from coming out of the mounting opening 114, and can be welded to the conductive member 3 to form the welding point 30, so that the mounting stability of the vibration component 2 can be improved, the welding can be facilitated, and the electrical connection reliability of the welding point can be improved. Optionally, when the side wall portion 112 includes an extension portion extending to a side of the vibrating component 2 facing away from the end cap portion 111, and at least a portion of the extension portion is bent inward relative to the side wall portion 112 to form a bent portion 113, a side of the bent portion 113 facing away from the vibrating component 2 may be welded to the conductive member 3, so as to facilitate the welding operation, and since the welding point 30 may be located at a side of the bent portion 113 facing away from the vibrating component 2, a collision of vibration of the vibrating component 2 to the welding point 30 may be reduced, which may cause a problem of damage or poor electrical connection of the welding point 30, and thus may ensure electrical connection stability of the welding point 30, improve electrical connection reliability of the conductive shell 11 and the electrical pulse generating device, and ensure effectiveness and reliability of the electrical stimulation massage.

When the side of the side wall portion 112 facing away from the end cover portion 111 defines the mounting opening 114, the bent portion 113 is located at the mounting opening 114, that is, the bent portion 113 may be flush with the mounting opening 114, or close to the mounting opening 114 and located at the inner side of the mounting opening 114 close to the end cover portion 111, or close to the mounting opening 114 and located at the outer side of the mounting opening 114 facing away from the end cover portion 111, and so on. Therefore, welding in a small space inside the conductive shell 11 can be avoided, so that a welding operable space is ensured, and since the welding point 30 is located at the mounting opening 114 and is not between the vibration component 2 and the conductive shell 11, the problem of poor electrical connection caused by the welding point 30 falling off due to friction between the vibration component 21 and the conductive shell 11 or the vibration component 2 during vibration is avoided. It is noted that the vibration member 2 is mounted inside the conductive shell 11, and in order to improve the compactness, the space between the conductive shell 11 and the vibration member 2 is insufficient, the welding operation is not easy, and the welding point 30 formed inside the conductive shell 11 is easily pressed by the vibration member 2.

Thus, since the side wall portion 112 includes the plurality of sub-wall sections 1121 arranged at intervals in the circumferential direction, the side wall portion 112 is easily deformed, so that the mounting of the vibration member 2 into the conductive shell 11 is facilitated, and the assembly of the conductive shell 11 with other parts (e.g., the later-described connection shell 12) and the like outside the conductive shell 11 is also facilitated by the characteristic that the side wall portion 112 is easily deformed. Moreover, since the side of the at least one sub-wall segment 1121 facing away from the end cover portion 111 has the bent portion 113, the bent portion 113 is easy to be disposed and bent, and the structure of the conductive shell 11 can be simplified.

As shown in fig. 6 and 8, in some embodiments of the present invention, the vibration member 2 may include a flexible sleeve 221, the flexible sleeve 221 is disposed in the unit housing 1, the vibration assembly 21 is disposed in the flexible sleeve 221, and the flexible sleeve 221 is interference-fitted between the conductive shell 11 and the vibration assembly 21, that is, the vibration assembly 21 and the conductive shell 11 press the flexible sleeve 221 together, or the flexible sleeve 221 has a certain elasticity, when the massage unit 100 is not installed in the unit housing 1 except for the flexible sleeve 221, the space in the unit housing 1 is insufficient to install the flexible sleeve 221 in an uncompressed state, when the vibration assembly 21 is installed in the flexible sleeve 221 and the flexible sleeve 221 is installed in the unit housing 1, the flexible sleeve 221 is interference-fitted between the unit housing 1 and the vibration assembly 21, and the flexible sleeve 221 is compressed by the co-pressing of the vibration assembly 21 and the unit housing 1 and accumulates elastic force, to improve the mounting stability and reliability of the vibration assembly 21 in the unit case 1.

Therefore, when the vibration component 21 vibrates, the vibration component 21 can stably and reliably drive the unit housing 1 to vibrate through the flexible sleeve 221, so that the unit housing 1 can form a reliable and effective vibration massage effect on a human body, namely, the reliability and the stability of the vibration massage function are improved. Also, since the flexible cover 221 is a flexible material member, it is possible to facilitate installation of the flexible cover 221 into the unit case 1 and installation of the vibration assembly 21 into the flexible cover 221.

Optionally, the welding end 115 of the bending portion 113 (i.e., the end used for forming the welding point 30) is isolated between the flexible sleeve 221 and the vibration component 21, i.e., the flexible sleeve 221 is disposed between the welding end 115 of the bending portion 113 and the vibration component 21, so that the flexible sleeve 221 can also play a role in buffering, the vibration component 21 is isolated from directly transmitting vibration to the welding point 30, the welding point 30 is prevented from being damaged or poorly connected by vibration, it is ensured that the electric connection between the conductive piece 3 and the conductive shell 11 is stable and reliable, and the reliability and stability of the electric stimulation massage function are improved.

Or alternatively, the welding end 115 of the bending part 113 (i.e., the end for forming the welding point 30) is non-contact fitted with the vibration assembly 21. For example, the vibration component 2 and the local part of the bending part 113 can be isolated by the flexible sleeve 221, so that the welding end part 115 of the bending part 113 and the vibration component 21 are suspended and have no contact, thereby effectively avoiding the welding point 30 from being damaged by vibration or being badly connected, ensuring that the electric connection between the conductive piece 3 and the conductive shell 11 is stable and reliable, and improving the reliability and stability of the electric stimulation massage function.

Accordingly, the positioning engagement between the first positioning groove 11221 and the first projection 2213 improves the positioning reliability between the peripheral buffering portion 2212 and the conductive shell 11, and further improves the mounting stability of the vibration member 2. In addition, during the process of installing the vibration component 2 into the installation opening 114, the first protrusion 2213 is matched with the first positioning groove 11221, so that the matching of the first protrusion 2213 and the first positioning groove 11221 can play a role of guiding and positioning, so that the flexible sleeve 221 can be quickly and accurately assembled in the conductive shell 11.

In addition, when the side wall portion 112 includes a plurality of sub-wall sections 1121 arranged at intervals in the circumferential direction, and a spacing groove 1122 penetrating to the mounting opening 114 is formed between two adjacent sub-wall sections 1121, the side wall portion 112 is easily deformed, and interference insertion of the side wall portion 112 into the connecting shell 12 is facilitated.

It should be noted that the connection housing 12 may be a separate component and assembled to be connected, or may be an integral component. For example, when being a separate piece and assembled together, the coupling housing 12 is assembled with the corresponding portion of the body 200. For example, when the connecting shell 12 is a single piece, at least a portion of the connecting shell and a corresponding portion of the housing 200 are a single piece, and may be formed by injection molding of a single material, or by secondary injection molding, for example, as long as the connecting shell is not detachable.

Alternatively, when the side wall portion 112 is inserted into the connection shell 12, the welding point 30 may be located in a space defined by the conductive shell 11 and the connection shell 12, that is, the welding point 30 is located in the unit housing 1, so that the problems of damage and poor connection caused by the welding point 30 being exposed outside the unit housing 1 may be avoided, thereby ensuring the reliability of the electrical connection between the conductive shell 11 and the electric pulse generating device, and thus ensuring the effectiveness and reliability of the electric stimulation massage.

In addition, when lateral wall portion 112 and connection shell 12 are the joint cooperation, utilize the cooperation location of second arch 1212 and second constant head tank 11222 for lateral wall portion 112 is accurate with the joint counterpoint of connection shell 12, can realize the joint smoothly, reduces the assembly degree of difficulty. Alternatively, the first positioning groove 11221 and the second positioning groove 11222 may be different spacing grooves 1122, so as to ensure that the functions of the first positioning groove 11221 and the second positioning groove 11222 do not interfere with each other or affect each other, and can effectively perform their functions.

It should be noted that the specific structure of the single outer case is not limited, and for example, the unit outer case 1 according to some specific embodiments of the present invention will be described below.

In some embodiments of the present invention, as shown in fig. 3, the unit case 1 may further include a connection case 12 in addition to the conductive case 11, the connection case 12 is adapted to be connected to the machine body 200, the connection case 12 is a separate member from the conductive case 11, and the vibration member 2 is adapted to be fitted into the conductive case 11 and/or the connection case 12 before the connection case 12 is assembled with the conductive case 11. Thereby, the ease of assembly of the vibration member 2 can be improved. In addition, it should be noted that "connection" in "the connection housing 12 is adapted to be connected to the machine body 200" is to be understood in a broad sense, and may be a separate member and assembled to be connected, or may be an integral member. For example, when being a separate piece and assembled together, the coupling housing 12 is assembled with the corresponding portion of the body 200. For example, when the connecting shell 12 is a single piece, at least a portion of the connecting shell and a corresponding portion of the housing 200 are a single piece, and may be formed by injection molding of a single material, or by secondary injection molding, for example, as long as the connecting shell is not detachable.

In some embodiments of the present invention, as shown in fig. 3, a side of the side wall part 112 facing away from the end cover part 111 defines a mounting opening 114, the vibration member 2 is adapted to be fitted in the conductive shell 11 through the mounting opening 114, the connecting shell 12 is connected to the conductive shell 11 to close the mounting opening 114, and the bent part 113 is located at the mounting opening 114. Therefore, the installation of the vibration component 2 is convenient, and the installation of the vibration component 2 is simple and reliable. Moreover, the bending portion 113 is located at the mounting opening 114, so that welding in a small space inside the conductive shell 11 is avoided, and a welding operable space is ensured, and the welding point 30 can also be located at the mounting opening 114 and is not located between the vibrating component 2 and the conductive shell 11, so that the problem of poor electrical connection caused by the fact that the welding point 30 falls off due to friction between the vibrating component 21 and the conductive shell 11 or the vibrating component 2 during vibration is avoided. It should be noted that, the vibrating component 2 is to be installed inside the conductive shell 11, in order to improve the structural compactness, the space between the conductive shell 11 and the vibrating component 2 is not enough, and the welding operation is not easy, and the welding point 30 formed inside the conductive shell 11 is easily extruded by the vibrating component 2, and the welding affects the installation of the vibrating component 21 at the top, and the welding affects the connection between the conductive shell 11 and the connecting shell 12 at the side, such as plugging, clamping or bonding.

For example, optionally, the vibration component 2 is interference-fitted in the conductive shell 11, so that the installation stability of the vibration component 2 can be improved, and the positioning and the limiting of the vibration component 2 can be simplified, for example, the vibration component 2 may include a buffer 22, such as a buffer sleeve, a buffer pad, etc., disposed between the conductive shell 11 and the vibration assembly 21, and the interference fit between the vibration component 2 and the conductive shell 11 is achieved by compression of the buffer 22.

Alternatively, when the connection shell 12 is connected to the conductive shell 11 to close the mounting opening 114, when the conductive shell 11 and the connection shell 12 are assembled in place, the welding point 30 may be located in a space defined by the conductive shell 11 and the connection shell 12, that is, the welding point 30 is located in the unit case 1, so that the problems of damage and poor connection due to the welding point 30 being exposed outside the unit case 1 may be avoided, thereby ensuring the reliability of the electrical connection between the conductive shell 11 and the electric pulse generating device, and thus ensuring the effectiveness and reliability of the electric stimulation massage.

In some embodiments of the present invention, as shown in fig. 3, the connecting shell 12 may include a hard mounting section 121, the hard mounting section 121 has a hollow cylindrical shape (may be, but is not limited to, a hollow cylindrical shape), and the sidewall portion 112 is inserted into the hard mounting section 121. Therefore, the assembly is convenient, the connection is reliable, the structure of the conductive shell 11 is simple, the processing is convenient, and the connection with the connecting shell 12 and the welding with the conductive piece 3 are not influenced.

Optionally, the side wall portion 112 is in interference fit and snap fit with the hard mounting segment 121. Thereby, a reliable connection of the connection shell 12 and the conductive shell 11 can be simply and efficiently achieved.

For example, as shown in fig. 4, 10 and 11, when the side wall portion 112 is engaged with the hard mounting segment 121, the hard mounting segment 121 may have a snap 1211 formed on an inner cylindrical surface thereof, the side wall portion 112 may have a snap hole 11210 formed thereon, and when the side wall portion 112 is inserted into the hard mounting segment 121, the snap 1211 is engaged with the snap hole 11210. Therefore, the side wall part 112 and the hard mounting section 121 can be inserted and clamped, so that the connecting shell 12 and the conductive shell 11 can be reliably connected, and the clamping is simple and reliable in implementation mode and convenient to process and produce.

For example, as shown in fig. 3 and 4, when the side wall portion 112 is inserted into the hard mounting section 121 with interference, the side wall portion 112 may include a plurality of sub-wall sections 1121 arranged at intervals along the circumferential direction, a spacing groove 1122 is formed between two adjacent sub-wall sections 1121, and a fastening hole 11210 is formed on the sub-wall section 1121. Therefore, since the side wall portion 112 includes the plurality of sub-wall sections 1121 arranged at intervals in the circumferential direction, the side wall portion 112 is easily deformed, interference insertion of the side wall portion 112 and the hard mounting section 121 is conveniently achieved, and the fastening holes 11210 are arranged on the sub-wall sections 1121, so that fastening of the fasteners 1211 and the fastening holes 11210 can be conveniently achieved in the insertion process, thereby improving the assembly efficiency and the assembly convenience, and further, the connection reliability and the connection stability of the vibration member 2 and the unit housing 1 can be improved by interference fit of the side wall portion 112 and the vibration member 2.

Further, as shown in fig. 4, 9 and 11, the spacing slot 1122 may penetrate the mounting opening 114 and include a second positioning slot 11222, so that the second positioning slot 11222 also penetrates the mounting opening 114, a second protrusion 1212 is formed on the inner surface of the hard mounting segment 121, and the second protrusion 1212 is fitted in the second positioning slot 11222, so that the second protrusion 1212 is smoothly fitted in the second positioning slot 11222 during the insertion of the side wall portion 112 into the hard mounting segment 121, so that the fitting of the second protrusion 1212 in the second positioning slot 11222 may serve as a guiding positioning, so that the side wall portion 112 can be quickly and accurately fitted in the hard mounting segment 121, and the positioning reliability of the conductive shell 11 and the connecting shell 12 is improved, and the mounting stability of the connecting shell 12 and the conductive shell 11 is further improved.

In other embodiments of the present invention, as shown in fig. 14-18, the connecting shell 12 may include a flexible mounting section 124, the flexible mounting section 124 includes an outer ring section 1242 and an inner ring section 1243, the inner ring section 1243 is disposed in the outer ring section 1242 and defines a plug-fit slot 1241 with the outer ring section 1242, the side wall portion 112 is plug-fit in the plug-fit slot 1241, and an avoiding notch 126 for avoiding the extending portion is formed on the inner ring section 1243. Therefore, through the insertion fit of the side wall part 112 and the insertion and distribution groove 1241, the connection shell 12 and the conductive shell 11 can be relatively limited, so that the connection reliability can be improved, the problem of assembly limitation is solved, and damage caused by excessive insertion is avoided. Alternatively, the sidewall 112 is adhered to the slot 1241, for example, glue may be injected through the slot 1241, and when the sidewall 112 is inserted into the slot 1241, adhesion may be achieved, so that the operation is easy and the connection is reliable.

In some embodiments of the present invention, as shown in fig. 4 and 10, and fig. 18, the conductive shell 11 may further include a side wall portion 112, the side wall portion 112 being connected to a side of the end cover portion 111 facing the machine body 200 and being disposed around an outer circumferential surface of the vibration member 2 and defining the mounting opening 114, the side wall portion 112 including an outer wall section 1123 and an inner wall section 1124 connected in sequence in a direction away from the end cover portion 111, a cross-sectional area S1 of the outer wall section 1123 being greater than a cross-sectional area S2 of the inner wall section 1124, the inner wall section 1124 being inserted and fitted into the connection shell 12, the outer wall section 1123 being located outside the connection shell 12 and an outer circumferential surface of the outer wall section 1123 being flush with an outer circumferential surface of the connection shell 12. Therefore, the cross section change of the outer wall section 1123 and the inner wall section 1124 can be utilized to play a role of inserting and limiting, and the appearance surface of the joint of the connecting shell 12 and the conductive shell 11 can be ensured to be smooth, so that the sealing performance of the inserting and matching position of the connecting shell 12 and the conductive shell 11 is improved. Optionally, the inner wall section 1124 is comprised of a plurality of sub-wall sections 1121.

In some embodiments of the present invention, as shown in fig. 13 and 16, the connection housing 12 may include a mounting section 1202 and a connection section 122, the mounting section 1202 being connected with the conductive housing 11, the connection section 122 being adapted to be connected between the body 200 and the mounting section 1202. For example, the mounting segment 1202 may be the rigid mounting segment 121 or the flexible mounting segment 124, which will not be described herein.

Alternatively, as shown in fig. 11 and 13, the connection section 122 is hard and is adapted to be a separate piece from the machine body 200, whereby the movement of the connection section 122 relative to the machine body 200 is easily achieved to ensure that the massage unit 100 can reliably perform the vibration massage function. For example, the connecting section 122 can be attached to a mounting surface of the inner housing of the housing 200, for example, by clamping the inner housing of the housing 200 together with the connecting section 122 by a clip. Furthermore, when the mounting section 1202 is the rigid mounting section 121 described above, in some alternative examples, the rigid mounting section 121 may be integral with the rigid connecting section 122 to simplify machining, or may be a separate piece.

Or alternatively, as shown in fig. 16 and 18, the connecting section 122 is of a flexible material and is adapted to be integral with the mounting plate 201 of the machine body 200. Thereby, the assembly steps can be reduced, and the flexibility of the connection section 122 can be utilized to ensure that the massage unit 100 can reliably perform the vibration massage function. In addition, a corrugated structure may be further provided at the junction of the coupling case 12 and the mounting plate 201, thereby performing a vibration damping function and facilitating vibration of the massage unit 100.

In addition, when the mounting section 1202 is the above-mentioned rigid mounting section 121, in some alternative examples, the rigid mounting section 121 and the flexible connecting section 122 may be a single piece or may be separate pieces. When the mounting section 1202 is the flexible mounting section 124, the flexible mounting section 124 and the flexible connecting section 122 may be a single piece or separate pieces.

In some embodiments, as shown in fig. 18, the connection housing 12 may be made of a flexible material and is adapted to be integrated with the mounting plate 201 of the machine body 200, so that the assembly steps can be reduced, and the flexibility of the connection section 122 can be utilized to ensure that the massage unit 100 can reliably perform the vibration massage function. For example, the connecting shell 12 and the mounting plate 201 can both be made of soft silica gel, so that the deformation is better, and the damping effect is better. When the connecting shell 12 is made of soft silica gel, the conductive shell 11 and the connecting shell 12 can be bonded and fixed, and reliable connection can be realized.

In some embodiments of the present invention, the connecting shell 12 is made of a non-conductive material, so as to improve the safety of use, and on the other hand, the connecting shell 12 can be made of a non-conductive material suitable for being connected with the machine body 200, for example, a material such as plastic or silicon gel is used to process the connecting shell 12, so as to meet the requirement of connecting the connecting shell 12 with the machine body 200.

In some embodiments of the present invention, the conductive shell 11 is a metal shell, that is, the conductive shell 11 is made of metal material, so as to facilitate processing of the conductive shell 11 on the one hand, and ensure a large conductive area on the other hand, and ensure that the conductive shell 11 can electrically stimulate and massage the human body no matter which part of the conductive shell 11 the human body contacts. Of course, the present invention is not limited thereto, and the conductive shell 11 may be partially made of a metal material, and the welding points 30 may be provided on the metal material, so that the metal material may be in contact with the human body to perform the electrical stimulation massage.

In some embodiments of the present invention, the connection housing 12 may include a stopper portion 1201 that stops at a side of the vibration member 2 facing away from the end cover portion 111. It should be noted that the "stop" described herein is not limited to a direct or indirect contact stop, and may also be a non-contact stop, for example, in which case the vibration member 2 may be stopped after moving a certain distance in a direction away from the end cover portion 111. Thus, the stopper portion 1201 can be used to limit and support the vibration member 2 to a certain extent, thereby improving the mounting stability and operational reliability of the vibration member 2.

The relative position and configuration of the stopper portion 1201 and the conductive case 11 are not limited. For example, in some alternative embodiments, as shown in fig. 6, the stopping portion 1201 may be located outside the conductive shell 11, so that the stopping portion 1201 may be prevented from occupying the space inside the conductive shell 11, so that the conductive shell 11 may be miniaturized.

For example, in the specific example shown in fig. 6 and 13, the connecting shell 12 may include a mounting section 1202 and a connecting section 122, the mounting section 1202 is connected to the conductive shell 11, the connecting section 122 is adapted to be connected between the machine body 200 and the mounting section 1202, the connecting section 122 and the mounting section 1202 are both hollow cylindrical, and the cross-sectional area S3 of the connecting section 122 is smaller than the cross-sectional area S4 of the mounting section 1202, so that the connecting portion of the mounting section 1202 and the connecting section 122 forms a step surface 123, and the step surface 123 serves as a stopper 1201 to stop against the vibration component 2. Therefore, the step surface 123 can be used for limiting and supporting the vibration part 2 to a certain extent, the mounting stability and the working reliability of the vibration part 2 are improved, and the connecting shell 12 is simple in structure and convenient to process and demold. Moreover, the stopper portion 1201 can be easily and effectively ensured to be located outside the conductive shell 11. Of course, the utility model is not limited to this, and the connecting shell 12 may be formed in other forms, for example, the connecting shell 12 may be a cylinder with a non-variable cross section, and the cylinder has an annular rib inside, and the annular rib is located outside the conductive shell 11 and stops the vibration member 2.

For example, in some alternative embodiments, as shown in fig. 16 and 18, the stopping portion 1201 may also extend into the conductive shell 11, thereby improving the compactness, making the stopping portion 1201 more accessible to the vibration member 2, and implementing a limit stop for the vibration member 2. For example, in the specific example shown in fig. 6, the connecting shell 12 includes an outer ring section 1242 and an inner ring section 1243, the inner ring section 1243 is disposed in the outer ring section 1242 and defines a plug-fit groove 1241 with the outer ring section 1242, the sidewall portion 112 is plug-fitted in the plug-fit groove 1241, and the inner ring section 1243 serves as a stopper portion 1201 to stop the vibration member 2.

From this, can utilize itself to participate in and inject the interior ring section 1243 of joining in marriage groove 1241 and form spacing and support to vibration part 2 to a certain extent to simplify and connect 12 structures of shell, need not additionally to process other structures, just can improve vibration part 2's installation stability and operational reliability. Moreover, the stopper portion 1201 can be easily and effectively ensured to be located in the conductive case 11. Of course, the utility model is not limited to this, and the connecting shell 12 may be formed in other forms, for example, the connecting shell 12 may be a cylinder with a non-variable cross section, and the cylinder has an annular rib inside, and the annular rib extends into the conductive shell 11 and stops the vibration component 2.

In some embodiments of the present invention, as shown in fig. 6, 12-13, the end of the unit housing 1 facing the machine body 200 has a through hole 125, one end of the conductive element 3 is located in the conductive shell 11 and welded to the conductive shell 11, and the other end of the conductive element 3 penetrates out of the unit housing 1 through the through hole 125 to be suitable for connecting the electric pulse generating device. Thus, it is not necessary to connect the conductive member 3 to a lead wire for connecting an electric pulse generating device in a narrow space inside the unit case 1, thereby improving operability. Moreover, since the conductive member 3 penetrates through the through hole 125 at the end of the unit case 1 facing the body 200, the distance between the conductive member 3 and the body 200 can be shortened, the conductive member 3 can be conveniently connected to the electric pulse generating device in the body 200, the appearance neatness can be improved, and the problems of electric leakage, damage and the like caused by the leakage of the conductive member 3 can be avoided.

In some embodiments of the present invention, as shown in fig. 3 and 6, the massage unit 100 may further include: the heat generating member 4 includes a heat generating portion 40 located between the vibration member 2 and the end cover portion 111, and the heat generating portion 40 can transfer heat to the end cover portion 111. That is, at least part of the heating member is disposed between the vibration member 2 and the end cover part 111 of the conductive case 11 to transfer heat to the end cover part 111, so that the end cover part 111 can perform a hot compress massage on the human body, thereby enriching the function of the massage unit 100. Since the welding point 30 is located on the side of the vibration member 2 away from the end cover portion 111, the installation of the heat generating portion 40 is not affected, and the heat generating portion 40 transfers heat to the end cover portion 111, so that the heat transfer efficiency is higher.
