Description

Technical Field

[0001] The utility model relates to the technical field of handheld massage appliances, and more specifically, to a head massager. Background Art

[0002] EMS (Electric Muscle Stimulation) is a muscle electrical stimulation technology that directly stimulates motor nerves through external current, triggering muscle contraction, thereby achieving the purpose of actively moving muscles. To conduct microcurrent from the PCB to the massage head, the head massager with EMS function on the market needs to connect the conductive wire from the PCB to the massage head area.

[0003] For example, the existing Chinese patent announcement number CN216496429U discloses a head massager with EMS, which includes a housing, a soft conductive massage head, a pulse generator installed in the housing, a gear box and a beveled cam connected to the output shaft of the gear box, the beveled surface of the beveled cam is movably equipped with a twisting base, the housing or housing of the gear box is provided with a rotation stop groove, the twisting base is provided with a rotation stop block, when the beveled cam drives the twisting base to twist, the rotation stop block is movably embedded in the rotation stop groove, the twisting base is provided with a conductive member, the outer end of the conductive member extends to the inner wall of the twisting base, when the soft conductive massage head is installed in the twisting base, the soft conductive massage head abuts against the conductive member; the inner end of the conductive member is electrically connected to the pulse generator through a flexible conductive member. Combined with its specification and drawings, it can be seen that the flexible conductive member adopts a spring or a soft wire, that is, the flexible conductive member needs to occupy the space inside the massage head, and there are relevant process requirements in assembly.

[0004] However, due to the size limitation of the massager itself, its internal space is small, and the product often has a waterproof requirement. Therefore, if connecting conductive wires are inserted inside the massage head, it will lead to complex design and difficult production and assembly. Utility Model Content

[0005] The utility model provides a head massager, which forms a continuous conductive chain by arranging a first conductive member and a second conductive member that keep in contact with each other between a PCB board, a power member, a transmission member and a massage head, thereby forming a conductive loop with a human body without connecting a conductive wire.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] Provided is a head massager, including a housing, a PCB board disposed on the housing, and a massage head assembly. The massage head assembly includes a first conductive member, a power member, a second conductive member, a transmission member, and a massage head. The power member is fixed on the housing. One end of the first conductive member contacts the PCB board, and the other end penetrates into the power member. One end of the second conductive member penetrates into the power member and keeps in contact with the first conductive member, and the other end is disposed through the transmission member. The massage head is connected to the transmission member and contacts the end of the second conductive member penetrating through the transmission member.

[0008] Further, the transmission member includes a swing rod and a swing rod sleeve sleeved on the lower end of the swing rod. The second conductive member includes a first conductive connecting shaft and a second conductive connecting shaft. One end of the first conductive connecting shaft penetrates into the power member and keeps in contact with the first conductive member, and the other end is disposed in the swing rod. The second conductive connecting shaft passes through the swing rod sleeve and connects the swing rod. The end of the second conductive connecting shaft connected to the swing rod keeps in contact with the first conductive connecting shaft, and the other end is exposed on the lower end surface of the swing rod sleeve. The massage head is connected to the swing rod sleeve and contacts the second conductive connecting shaft exposed on the lower end surface of the swing rod sleeve.

[0009] Furthermore, the transmission member further includes a swing rod positioning member fixed on the housing. The upper end of the swing rod is provided with a spherical head. An accommodating cavity for accommodating the rotation of the spherical head is provided in the swing rod positioning member. One end of the first conductive connecting shaft is disposed in the swing rod, and the other end passes through the swing rod positioning member and then enters the power member and keeps in contact with the first conductive member.

[0010] As an improvement, the end of the first conductive connecting shaft in contact with the first conductive member has a spherical structure.

[0011] Preferably, conductive grease is filled at the contact between the first conductive connecting shaft and the first conductive member and at the contact between the second conductive connecting shaft and the first conductive connecting shaft.

[0016] Compared with the prior art, the head massager of the present utility model is a head massager with EMS function that does not require connecting conductive wires.

[0022] As Figures 1 to 4 shown is an embodiment of the head massager of the present utility model. As Figure 1 , Figure 2 and Figure 3As shown in the figure, the head massager of this embodiment includes a housing 1, a PCB board 10 disposed on the housing 1, and a massage head assembly 2. The massage head assembly 2 includes a first conductive member 20, a power member 30, a second conductive member 40, a transmission member 50, and a massage head 60. Among them, the power member 30 is fixed on the housing 1; one end of the first conductive member 20 contacts the PCB board 10 and the other end penetrates into the power member 30; one end of the second conductive member 40 penetrates into the power member 30 and remains in contact with the first conductive member 20, and the other end is disposed through the transmission member 50; the massage head 60 is connected to the transmission member 50, and the massage head 60 contacts the end of the second conductive member 40 that penetrates through the transmission member 50. It should be noted that in actual applications, in order to achieve a better conduction effect, the first conductive member 20 and the second conductive member 40 are usually made of stainless steel.

[0023] This head massager is a head massager with EMS function that does not need to be connected to a conductive wire. By arranging the first conductive member 20 and the second conductive member 40 that are in contact with each other between the PCB board 10, the power member 30, the transmission member 50, and the massage head 60, the PCB board 10, the first conductive member 20, and the second conductive member 40 form a coherent conductive chain, and thus there is no need to weld a conductive wire, so that the massager forms a conduction loop with the human body.

[0024] In an improved embodiment, as Figure 3 and Figure 4 shown, the transmission member 50 includes a swing rod 51 and a swing rod sleeve 52 sleeved on the lower end of the swing rod 51. The second conductive member 40 includes a first conductive connecting shaft 41 and a second conductive connecting shaft 42. It should be noted that in this embodiment, with the power member 30 being above, the transmission member 50 is below accordingly. One end of the first conductive connecting shaft 41 penetrates into the power member 30 and remains in contact with the first conductive member 20, and the other end is disposed in the swing rod 51; the second conductive connecting shaft 42 passes through the swing rod sleeve 52 and connects the swing rod 51. One end of the second conductive connecting shaft 42 connected to the swing rod 51 remains in contact with the first conductive connecting shaft 41, and the other end is exposed on the lower end surface of the swing rod sleeve 52; the massage head 60 is connected to the swing rod sleeve 52, and the massage head 60 remains in contact with the second conductive connecting shaft 42 exposed on the lower end surface of the swing rod sleeve 52. That is to say, since the first conductive connecting shaft 41 and the first conductive member 20, and the second conductive connecting shaft 42 and the first conductive connecting shaft 41 always remain in contact, after the upper end of the first conductive member 20 contacts the PCB board 10, the conductive chain is formed in sequence from the first conductive member 20, the first conductive connecting shaft 41, and the second conductive connecting shaft 42, and no additional conductive wire is required during the process.

[0025] In yet another improved embodiment, since the transmission member 50 is driven by the power member 30 to rotate, specifically, the swing rod 51 swings with the power member 30. To ensure the stability of its movement, as Figure 3 、Figure 4 As shown, the transmission member 50 further includes a swing rod positioning member 53 fixed to the housing 1. Among them, the upper end of the swing rod 51 is provided with a spherical head portion 511. An accommodating cavity 531 for accommodating the rotation of the spherical head portion 511 is provided in the swing rod positioning member 53. One end of the first conductive connecting shaft 41 is inserted into the swing rod 51, and the other end passes through the swing rod positioning member 53 and then enters the power member 30 and remains in contact with the first conductive member 20.

[0026] In a preferred embodiment, in order to ensure that the swing rod 51 does not affect the stable formation of the conductive chain during the swinging movement, the end of the first conductive connecting shaft 41 in contact with the first conductive member 20 has a spherical structure 411.

[0027] In addition, in order to further improve the overall conductive performance and form a coherent conductor, conductive grease is filled at the contact between the first conductive connecting shaft 41 and the first conductive member 20 and at the contact between the second conductive connecting shaft 42 and the first conductive connecting shaft 41, which can not only enhance the contact conductivity but also does not affect the movement of the swing rod 51; in addition, the contact points between the first conductive member 20 and the PCB board 10 are tinned on the pads.

[0028] In a preferred embodiment, as Figure 2 shown, the power member 30 includes a gear box housing member 31 and an inclined surface gear 32 provided in the gear box housing member 31. The first conductive member 20 passes through the inclined surface gear 32 and is fixed to the gear box housing member 31, and the gear box housing member 31 is fixed to the housing 1. That is, in actual use, after the gear box housing member 31 positions the first conductive member 20 and keeps it in contact with the PCB board 10, the rotation of the inclined surface gear 32 on the gear box housing member 31 can drive the swing rod 51 to make a circular swing, so that the massage head 60 also swings and rotates accordingly.

[0029] As an improvement to the above embodiment, two or more sets of massage head assemblies 2 are provided on the housing 1, and the first conductive members 20 on each set of massage head assemblies 2 are all in contact with the PCB board 10 on the housing 1 to form the above-mentioned conductive chain, so as to form a conduction loop with the human body.

[0030] In the embodiment of the present invention, the massage head 60 is a conductive silicone massage head. It can be understood that in order to achieve a better conduction effect, the first conductive member 20 and the second conductive member 40 can be made of stainless steel. Therefore, in this embodiment, the first conductive member 20 can be a steel shaft; the first conductive connecting shaft 41 is another round head steel shaft, and its round head end has a spherical structure 411 so as to remain in contact with the aforementioned steel shaft when the swing rod 51 swings; the second conductive connecting shaft 42 is a stainless steel strip-shaped screw, and the swing rod sleeve 52 and the swing rod 51 are locked by the stainless steel strip-shaped screw; the inclined surface gear 32, the swing rod 51, the swing rod positioning member 53 and the swing rod sleeve 52 can be made of one or several of PA66, POM or conductive nylon.

[0031] The head massager of the present utility model solves the design problems caused by small space and the need for waterproofing of the product, not only saving internal space, but also simplifying the structure, making production and assembly more convenient.

[0032] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
