The vagus nerve is involved in human inflammation, emotion and pain regulation, and research shows that the vagus nerve is stimulated to regulate brain, heart and gastrointestinal functions, and has therapeutic effects on epilepsy, depression and the like. Of course, besides the medical effect, the simple massage stimulation of the external ear (comprising auricles and external auditory meatus) can also play a good role in relaxing body and mind and relieving fatigue, so that the ear picking service industry is more and more popular in recent years.

At present, the service of massaging and stimulating the ears is completed manually, for example, the ear picking massage service industry has the defects of nonstandard and uneven service techniques, and the user experience is good and bad. Therefore, a new ear-stimulating technical scheme is needed to meet the use requirements of users, standardize and normalize the stimulating actions, and ensure the experience quality of the stimulating actions.

In view of this, the present utility model proposes an ear device, referring to fig. 1 to 3, which in one embodiment of the utility model comprises:

a housing 10;

the driving assembly 20 is arranged on the shell 10, the driving assembly 20 comprises a first driving piece 21 and a transmission flexible shaft 22, and the first driving piece 21 is used for driving the transmission flexible shaft 22 to rotate; and

the ear canal massage part 30 is drivingly connected to the transmission flexible shaft 22, and the ear canal massage part 30 is configured to extend into the external auditory canal of the user and rotationally contact the external auditory canal.

In the technical scheme of the utility model, the first driving piece 21 is used for driving the transmission flexible shaft 22 to rotate, so that the ear canal massage piece 30 connected with the transmission flexible shaft 22 is driven to rotate, and the ear canal massage piece 30 contacts and stimulates the epidermis of the external auditory canal in the movement process, thereby realizing the stimulation of the vagus nerve on the external auditory canal, and enabling a user to enjoy the effects of relaxing body and mind and relieving fatigue simply and conveniently. Specifically, the first driving member 21 may be one of a servo motor, a stepping motor, a hydraulic motor, or a pneumatic motor. Because the ear device is produced and manufactured by an industrial production line in a unified way, the stimulation mode of the ear device can be standardized and normalized, namely, the quality of the stimulation action is unified and controlled at the source, so that the experience quality of the stimulation action can be ensured. Secondly, the advantage that the transmission flexible shaft can extend along a curve is utilized, so that the arrangement space in the casing 10 can be planned better, the arrangement of the first driving piece 21 and other internal parts is more compact, and the miniaturized design of the ear device is facilitated.

In addition, referring to fig. 1, the housing includes a proximal ear (referring to the support arm 120 in fig. 1) and a distal ear (referring to the wearing part 110 in fig. 1), the ear canal massage device 30 is disposed at the proximal ear, and the first driving device is disposed at the distal ear. Therefore, under the support of the transmission flexible shaft 22, the first driving piece 21 is far away from the ear canal massage piece 30, so that the working noise transmitted to the ear canal massage piece 30 when the first driving piece operates is reduced, and the perception degree of the working noise of the first driving piece by a user can be reduced, so that the user experience is improved.

It can be appreciated that the ear device according to the technical solution of the present utility model can be mounted on other equipment or facilities, such as a massage armchair, a bed or furniture, so as to provide better and richer use functions for the user in combination with the basic functions of the other equipment or facilities; can also be arranged as a wearable device, thereby improving the convenience of use of the ear device. Of course, the ear device may also be provided as a wearable device and be detachably mounted with other devices or facilities. It should be noted that the wearable device refers to a portable device that is directly worn on the body or integrated into the clothing or accessories of the user, such as an ear-hanging earphone, a headphone, a neck-hanging earphone, or VR/MR/AR glasses, etc. In this embodiment, the ear device is configured as a wearable structure.

Referring to fig. 1 and 2, in an embodiment, the ear device further includes a wearing portion 110, a supporting arm 120 connected to the wearing portion 110, and an in-ear earplug 12 disposed on the supporting arm 120, the wearing portion 110 is used to be worn on a neck of a user, the in-ear earplug 12 is used to be worn on an exit of an external auditory canal, the in-ear earplug 12 is provided with an avoidance hole (not shown in the drawings), the first driving member 21 is disposed on the wearing portion 110, the transmission flexible shaft 22 is disposed through the wearing portion 110 and the supporting arm up to the in-ear earplug 12, and the ear canal massage member 30 can be disposed through the avoidance hole and connected with the transmission flexible shaft 22. In this way, the wearing portion 110 can obtain a supporting force from the neck of the user, so that the pressing force of the in-ear earplug 12 to the ear is reduced, and the ear device is more comfortable to wear. In addition, the in-ear type earplug 12 can effectively block external noise from entering the external auditory meatus, and the external noise comprises noise generated when the first driving member 21 operates, so that the perception degree of the external noise by a user is reduced, and the user experience is improved.

In one embodiment, the ear canal massage 30 includes a hair-like portion for contacting the external auditory canal. Specifically, the hair-shaped part can be configured into natural fibers or chemical fibers or elastic materials, namely, the hair-shaped monomers are prepared by using raw materials such as the natural fibers or the chemical fibers or the elastic materials, and a plurality of hair-shaped monomers can be combined into a bundle or a ball according to the requirement so as to form structures similar to feathers or silica gel soft brushes or hair brushes or cotton swabs; of course, only one hair-like monomer, for example, one horsetail hair, may be used as the hair-like portion. The natural fibers include plant fibers including cotton, hemp, flax, and the like, and animal fibers including animal hair such as horsetail, pig hair, goat hair, or feathers; the chemical fibers comprise artificial fibers and synthetic fibers, wherein the artificial fibers comprise artificial protein fibers, viscose fibers, acetate fibers, cuprammonium fibers and the like, and the synthetic fibers comprise terylene, chinlon, acrylic fibers and the like; the elastic material comprises silica gel, rubber, elastic PVC (Polyvinyl chloride) and the like. Thus, the natural fiber, the chemical fiber or the elastic material is easy to obtain or prepare, and the related industrial production technology is mature, so that the manufacturing cost of the wool part can be effectively reduced. In addition, the hair-like portion made of these natural fibers or chemical fibers can be made into a hair-like shape, and the individual body is slim and soft, so that a good feeling stimulation effect can be achieved. Of course, in other embodiments, the bristles may be configured from other materials that can be made into a soft bristle shape, or from materials that can be made into a flexible or elastomeric body, such as a foam sponge, or the like.

Referring to fig. 1, in order to make the extension of the ear canal massage part 30 adjustable relative to the casing 10, in an embodiment, the casing 10 is provided with a telescopic cavity (not shown in the drawing) for the transmission flexible shaft 22 to movably pass through, and a telescopic opening 10b communicating with the telescopic cavity and disposed towards the ear canal massage part 30, and the ear device further comprises a depth adjusting part 40, wherein the depth adjusting part 40 is used for driving the transmission flexible shaft 22 to make a telescopic movement close to or far from the telescopic opening 10 b. That is, the depth adjusting member 40 can drive the protruding length of the ear canal massage member 30 on the transmission flexible shaft 22 with respect to the casing 10, thereby adjusting the depth of the ear canal massage member 30 protruding into the external auditory canal. In this way, the ear device can be adapted to different users and different usage situations, wherein when the users change the ear canal massage 30 with different forms, the proper telescopic position of the transmission flexible shaft 22 can be selected according to the form of the ear canal massage 30, so that better product experience is obtained.

Specifically, the depth adjusting member 40 has a plurality of forms, for example, referring to fig. 1, 2 and 3, in one embodiment, the depth adjusting member 40 is connected to the flexible shaft 22, and the length of the flexible shaft 22 is greater than the length of the telescopic cavity. Specifically, the length of the flexible shaft 22 in the telescopic cavity is rich, and it can be seen that the flexible shaft 22 has a portion bent into a zigzag shape in fig. 2 or 3, and the bent portion can be straightened by the depth adjusting member 40 so that one end of the flexible shaft 22 can approach or extend out of the telescopic opening 10b toward the telescopic opening 10b, and when the bent portion is bent again, one end of the flexible shaft 22 is retracted. Therefore, the extending length of the ear canal massage part 30 can be realized by only independently driving the transmission flexible shaft 22 to extend and retract, the structure is simple, and the extension and retraction of the transmission flexible shaft 22 are smooth and stable.

For another example, referring to fig. 4, fig. 4 is a schematic structural view of a driving assembly, a depth adjusting member and a casing in another embodiment of the ear device. Referring to fig. 1 and 5 together, in another embodiment, the depth adjusting member 40 is connected to the transmission flexible shaft 22, and the first driving member 21 is slidably connected to the casing 10 along a direction approaching or separating from the telescopic opening 10 b. It should be noted that, in this embodiment, the length of the transmission flexible shaft 22 is less than or equal to the length of the telescopic cavity, that is, the length of the transmission flexible shaft 22 in the telescopic cavity is not excessive, and when the transmission flexible shaft 22 stretches in the telescopic cavity, the first driving member 21 is driven to do sliding motion. Specifically, the housing 10 is provided with a chute 10c, and the first driving member 21 is provided with a slider 211 protruding corresponding to the chute 10c, and the slider 211 is slidably connected to the chute 10 c. Of course, in other embodiments, the casing 10 may be provided with a guide rod, and the first driving member 21 may be provided with a slip ring, which is sleeved and slidably connected to the guide rod.

Of course, the mounting structure of the depth adjusting member 40 may be other types, for example, please refer to fig. 6, and fig. 6 is a schematic structural diagram of the driving assembly, the depth adjusting member and the casing in still another embodiment of the ear device. Referring to fig. 1 together, in a further embodiment, the first driving member 21 is slidably connected to the casing 10 along a direction approaching or separating from the telescopic opening 10b, and the depth adjusting member 40 is connected to the first driving member 21. In this way, the depth adjusting member 40 directly drives the first driving member 21 to slide on the casing 10, and the transmission flexible shaft 22 on the first driving member 21 can also generate telescopic motion relative to the telescopic cavity, so as to adjust the extension length of the ear canal massage member 30. Specifically, the depth adjusting member 40 is configured to be rotatably connected to the second rotating wheel 42 of the casing 10, the second rotating wheel 42 is provided with a third engaging tooth portion 421, and the first driving member 21 is provided with a fourth engaging tooth portion 212 for engaging and connecting the third engaging tooth portion 421. In this way, by using the engagement transmission method of the third engagement tooth 421 and the fourth engagement tooth 212, the transmission can be smoother and more stable, and the sliding of the first driving member 21 can be smoother and more stable. Of course, in other embodiments, the depth adjusting member 40 may be a pushing slider or a push-pull rod slidably connected to the casing 10, and the pushing slider or the push-pull rod is further connected to the first driving member 21.

Of course, in addition to the above-described manual adjustment of the depth adjustment member 40 to achieve the adjustment of the protruding length of the ear canal massage member 30, an electric adjustment may be implemented. Specifically, referring to fig. 7, fig. 7 is a schematic structural diagram of a driving assembly and a casing of a further embodiment of the ear device. Referring to fig. 1, the casing 10 is provided with a telescopic cavity through which the transmission flexible shaft 22 movably passes, and a telescopic opening 10b which is communicated with the telescopic cavity and is arranged towards the ear canal massage part 30, and the first driving part 21 is connected to the casing 10 in a sliding manner along a direction approaching or separating from the telescopic opening 10 b; the driving assembly 20 further comprises a driving and reversing shaft 23 connected to the first driving member 21, and a driving and reversing wheel 24 connected to the driving and reversing shaft 23, wherein the driving and reversing wheel 24 is also connected to the casing 10 in a rolling manner and is used for driving the first driving member 21 to slide relative to the casing 10. In this way, the first driving member 21 drives the transmission flexible shaft 22 to rotate and drives the advancing and retreating wheel 24 to roll relative to the casing 10, and is influenced by the reaction force of the casing 10 to the advancing and retreating wheel 24 in the rolling process, and the first driving member 21 can slide in the direction approaching or separating from the telescopic opening 10b, so that the extending length of the ear canal massage member 30 is adjusted. That is, an electric adjustment function is provided to the user so that the protruding length of the ear canal massage 30 can be controlled to be adjusted in place by the first driving member 2121, thereby improving the convenience of use of the ear device.

Specifically, in yet another embodiment, the casing 10 is provided with the driving and reversing rack 11 corresponding to the driving and reversing wheel 24, the extending direction of the driving and reversing rack 11 is parallel to the sliding direction of the first driving member 21, at least one convex tooth 241 is provided on the outer periphery of the driving and reversing wheel 24, and the convex tooth 241 is movably engaged with the driving and reversing rack 11. Parallel refers to parallel and near parallel. In this way, the first driving member 21 can slide smoothly and stably relative to the chute 10c by the engagement transmission between the teeth 241 on the advance and retreat wheel 24 and the advance and retreat rack 11. Of course, in other embodiments, the driving wheel 24 may be configured as an eccentric cam, and the casing 10 is provided with a rubber strip corresponding to the driving wheel 24, and the eccentric cam can at least partially push against the rubber strip during rotation, and slide the first driving member 21 along the chute 10c by virtue of friction force between the eccentric cam and the rubber strip.

Of course, the technical solution of the further embodiment may also be combined into another embodiment, thereby providing the user with both the manual adjustment function and the electric adjustment function. Thus, the depth adjusting member 40 and the advancing and retreating wheel 24 provide two operation modes for adjusting the extending length of the ear canal massage member 30 for the user to select according to the user's requirement, for example, the first driving member 21 can be selected and controlled to drive the advancing and retreating wheel 24 to perform coarse adjustment, and then the manual operation of the depth adjusting member 40 is selected to perform fine adjustment; alternatively, only an electric adjustment function or only a manual adjustment function is used.

Specifically, the first driving member is used to drive the transmission flexible shaft 22 and the driving wheel and reversing wheel in various manners, for example, in another embodiment, the driving assembly 20 further includes a reducer 25, the reducer 25 has an input shaft (not shown in the drawing), a first output shaft (not shown in the drawing), and a second output shaft (not shown in the drawing), the input shaft is in driving connection with the first driving member 21, the transmission flexible shaft 22 is in driving connection with the first output shaft, and the driving and reversing shaft 23 is in driving connection with the second output shaft. Thus, the first driving member 21 can drive the transmission flexible shaft 22 to rotate and drive the advancing and retreating wheel 24 to roll, so that the structure of the driving assembly 20 is simplified, the miniaturized design of the ear device is facilitated, and the manufacturing cost of the ear device can be reduced. Of course, in other embodiments, two first driving members 21 may be provided, the driving and reversing shaft 23 is connected to one of the first driving members 21 in a driving manner, and the transmission flexible shaft 22 is connected to the other first driving member 21 in a driving manner. That is, the driving flexible shaft 22 and the advancing and retreating wheel 24 are independently controlled by the two first driving parts 21, which is beneficial to make the operation logic of the ear device more rich and variable.

In still another embodiment, the first driving member may further include a speed reducer, the speed reducer includes an input shaft, a first output shaft and a second output shaft, the input shaft is in driving connection with the first shaft, two transmission flexible shafts are provided, the two transmission flexible shafts are respectively in driving connection with the first output shaft and the second output shaft, and the advancing and retreating shaft is in driving connection with the second shaft. Therefore, the first driving piece drives the two transmission flexible shafts and the driving wheel simultaneously, the structure of the driving assembly can be obviously simplified, the miniaturized design of the ear device is facilitated, and the manufacturing cost of the ear device can be reduced.

Referring to fig. 4, in another embodiment, the driving assembly 20 further includes a first reduction gear 26 and a second reduction gear 27, the first reduction gear 26 is drivingly connected to the driving and reversing shaft 23, the second reduction gear 27 is meshed with the first reduction gear 26 and is relatively fixedly mounted on the driving and reversing wheel 24, and an axis of the second reduction gear 27 is parallel to an axis of the driving and reversing wheel 24; the outer periphery of the advance and retreat wheel 24 is provided with a convex tooth 241, and the convex tooth 241 is close to the advance and retreat rack 11 and is not meshed with the advance and retreat rack 11. In this way, the central angles through which the driving and reversing wheel 24 and the transmission flexible shaft 22 rotate can be made inconsistent, and different control modes can be implemented on the driving and reversing wheel 24 in the working state and the shutdown state of the ear device. Specifically, assuming that the rotation ratio of the first output shaft to the second output shaft is 1 and the transmission ratio of the first reduction gear 26 to the second reduction gear 27 is less than one sixth, it is possible to set the ear device in an operating state, in which the first output shaft rotates in a manner of alternating between 6 forward rotations and 6 reverse rotations, so that the teeth 241 on the advancing and retreating wheel 24 fail to rotate one full rotation when the transmission flexible shaft 22 rotates, that is, the advancing and retreating wheel 24 is not engaged with the advancing and retreating rack 11 all the time, that is, is not affected by the reaction force of the advancing and retreating rack 11, so that the first driving member 21 does not slip with respect to the casing 10 (the advancing and retreating rack 11). Then, the ear device is set in the off state, and the second output shaft rotates according to the preset rotation direction until the convex teeth 241 on the advancing and retreating wheel 24 are meshed with the advancing and retreating rack 11, and the first driving piece 21 is driven to reset to the initial position. The preset rotational direction refers to a rotational direction in which the driving and reversing wheel 24 rotates when the second output shaft rotates to displace the driving and reversing wheel in a direction approaching the initial position. In this way, the driving and reversing wheel 24 can be made to function only to drive the first driving member 21 to return, that is, the driving and reversing wheel 24 is made to function not in the ear device operating state but only in the ear device off state. It should be noted that, in the off state, the user selects to cut off the working power supply of the ear device through the control key, but at this time, the working power supply of the ear device is still not stopped, and the first driving member 21 is continuously driven to rotate, and after the driving wheel 24 is reset to the initial position, the working power supply is cut off formally. Of course, the first reduction gear 26 and the second reduction gear 27 may be replaced with a first pulley, a second pulley, and a belt connected between the first pulley and the second pulley, or replaced with a first gear, a second gear, and a chain connected between the first gear and the second gear; that is, the structure for achieving the deceleration is not limited to the gear engagement structure, and any structure may be used as long as the structure can achieve the deceleration. In addition, the gear ratio of the first reduction gear 26 and the second reduction gear 27 is in the above range, and may be other value ranges, for example, the gear ratio is set to one third, one fourth, one seventh, one tenth, one twentieth, or the like.

Referring to fig. 1 to 3, in order to improve the smoothness of the depth adjustment member 40 driving the driving flexible shaft 22 to extend and retract, in an embodiment, the depth adjustment member 40 is configured to rotate the first rotating wheel 41 connected to the housing 10, the first rotating wheel 41 is provided with a first engaging tooth 411, and the driving flexible shaft 22 is provided with a second engaging tooth 221 for engaging and connecting with the first engaging tooth 411. In this way, by using the engagement transmission manner of the first engagement tooth 411 and the second engagement tooth 221, the transmission can be smoother and more stable, so that the telescopic movement of the transmission flexible shaft 22 in the telescopic cavity can be smoother and more stable. Of course, in other embodiments, the depth adjusting member 40 may be slidably connected to a pushing slider or a push-pull rod of the casing 10, where the pushing slider or the push-pull rod is further connected to the transmission flexible shaft 22.

Referring to fig. 3, in an embodiment, the first engaging tooth 411 extends along the circumferential direction of the first rotating wheel 41, and the second engaging tooth 221 is at least partially surrounded on the outer periphery of the first engaging tooth 411. In this way, the effective engagement length between the first engagement tooth 411 and the second engagement tooth 221 can be increased, so that the engagement transmission is smoother and more stable, and the smoothness of the extension and retraction of the transmission flexible shaft 22 in the extension and retraction cavity is improved. Of course, in other embodiments, the second engaging tooth 221 may also be provided to extend linearly.

Referring to fig. 3, in an embodiment, the driving assembly 20 further includes a reducer 25 drivingly connected to the first driving member 21, and the transmission flexible shaft 22 is connected to the reducer 25. In general, when feathers, horsehair, or the like are used as the material of the hair-like portion, the hair-like portion gently moves in the external auditory meatus, and a better massage stimulation effect can be achieved. Therefore, the rotation frequency of the ear canal massage 30 can be brought to a retarded state by the decelerator 25, thereby improving the massage stimulation effect. Of course, in other embodiments, it is also possible to not provide the decelerator 25, but to connect the first driving member 21 directly with the transmission flexible shaft 22.

In one embodiment, the first driving member 21 has a first shaft, and the transmission flexible shaft 22 is in driving connection with the first shaft, so that the first driving member 21 can drive the first shaft to rotate in a forward direction or a reverse direction. In this way, forward and reverse rotation of the transmission flexible shaft 22 and the ear canal massage part 30 thereon can be realized by forward and reverse rotation of the first driving part 21, and the forward and reverse rotation is stopped for a while during switching, thereby enriching the stimulation modes and improving the stimulation effect.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
