Description

[0001] Priority information: This application claims priority to Chinese patent application No. 202310946396.8 filed on July 31, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The utility model relates to a health care device, in particular to a massage head and a throat massager. Background Art

[0003] In the medical industry, some people suffer from swallowing and articulation disorders due to certain diseases or injuries caused by non-mechanical reasons, and need to be evaluated, treated and trained for swallowing and articulation disorders caused by these injuries to the larynx. Currently, electrodes are attached to the corresponding parts of the larynx to stimulate the nerve muscles through electrical stimulation. Through muscle retraining and functional stimulation of the laryngeal muscles, the normal contraction of the pharyngeal muscles is achieved, so that the patient's laryngeal swallowing function is improved.

[0004] Electrode therapy devices require electric shock treatment, which is quite harmful to the human body. Mild cases may cause local tingling and numbness, while severe cases may cause skin burns and muscle necrosis, and some injuries are irreversible.

[0005] At present, there are also some physical therapy devices that use vibration massage to relieve and improve patients' dysphagia. For example, the Chinese invention patent application with publication number CN109077916A discloses a laryngohyoidal muscle massager. The vibration of the vibrator drives the massage ball to vibrate. The massage ball rolls back and forth and vibrates on the surface of the laryngohyoidal muscle to stimulate the muscle activity of the throat, promote the movement of lifting the larynx, and improve the swallowing function.

[0006] The massager of the above structure needs to hold the handle to apply pressure to the throat, and then the massage balls drive the vibration, which is inconvenient to use. There are also some neck-worn throat massage devices. For example, the Chinese utility model patent with publication number CN204521505U discloses a throat massager, which uses a strap to fix the bracket with massage beads to the neck, without the need for the user to hold it continuously, making it more convenient to use. For another example, the Chinese utility model patent with publication number CN207545444U discloses a throat reliever, which is provided with a support frame that can be mounted on the neck of the human body, so that the throat reliever can be mounted on the neck and used without being held by hand.

[0007] The inventors have found that the throat massage device of the above structure still has certain defects. For example, when the throat massager is in use, the pressure of the throat massager on the skin cannot be detected. Too much or too little pressure is not conducive to ensuring the comfort and effect of use.

[0008] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Utility Model Content

[0062] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0063] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0064] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0065] like Figures 1 to 3 As shown, a throat massager corresponding to a preferred embodiment of the utility model includes a neck-mounted bracket 1, two massage heads 2, a first pressure sensor 3, a sheet 4 and a position adjustment device 5.

[0066] The neck-mounted support 1 is used to be mounted on the human neck, and the whole is in a curved arc shape. When the throat massager is worn on the neck, the middle part of the neck-mounted support 1 corresponds to the back side of the human neck (i.e. the neck), and its two ends 12 extend to the front side of the neck.

[0067] The neck-worn bracket 1 is elastic, and its two ends 12 are spaced apart and can be easily pulled apart to be worn on the neck. As a preferred embodiment, the neck-worn bracket 1 includes an elastic metal wire 10 and a silicone layer 11 coated on the outside of the elastic metal wire 10. The elastic metal wire 10 can be, for example, a titanium wire, which can be elastically deformed after being subjected to force and return to its original shape when the force is lost, so that the throat massager can be conveniently worn on the neck.

[0068] The two massage heads 2 are respectively arranged at the two ends of the neck-mounted bracket 1, and the massage heads 2 include a working head 20 for contacting the skin and a vibration device 21 for driving the working head 20 to vibrate. After the vibration device 21 vibrates, it drives the working head 20 to vibrate, and the working head 20 contacts the human skin, and can apply the vibration to the human body, thereby playing a massage or treatment role. Usually, after wearing, the two working heads 20 are respectively attached to the left and right sides near the front of the neck.

[0069] The first pressure sensor 3 is used to detect the pressure of the massage head 2 on the skin. Through the pressure value detected by the first pressure sensor 3, it can be conveniently determined whether the pressure of the massage head 2 on the human body is within a suitable range.

[0070] The sheet body 4 is movably connected to the neck-mounted bracket 1 and is used to support the back of the human neck.

[0071] The position adjustment device 5 is connected to the sheet 4 and is used to move the sheet 4 to adjust the distance between the sheet 4 and the working head 20. In this way, the throat massager can adapt to people with different neck thicknesses and has better adaptability. Moreover, since the width of the sheet 4 can be made larger, the fitting area on the neck is larger and it is more comfortable to wear.

[0072] It is understandable that when the distance between the sheet body 4 and the working head 20 is reduced, the pressure of the massage head 2 on the skin will also increase. Conversely, when the distance between the sheet body 4 and the working head 20 is increased, the pressure of the working head 20 on the skin will decrease. Therefore, the position of the sheet body 4 can be adjusted by the position adjustment device 5 to adjust the pressure of the working head 20 on the skin, so that the massage of the human body by the working head 20 is more comfortable. Usually, in a certain suitable pressure range, the vibration of the working head 20 has the best soothing or therapeutic effect. Therefore, by adjusting the pressure of the working head 20 and detecting whether the pressure value is appropriate through the first pressure sensor 3, it can be ensured that the working head 20 is in a suitable pressure range, and the use effect of the throat massager is more stable, the work is more efficient, and it is not easy to cause discomfort to the user due to excessive pressure, or even cause damage to the human body.

[0073] The position of the first pressure sensor 3 is not limited, as long as it can accurately detect the pressure of the working head 20 on the skin.

[0074] In some embodiments, Figure 4 As shown, the first pressure sensor 3 is disposed in the working head 20. It can be understood that Figure 4 The portion of the working head 20 in contact with the human body is in the shape of a plate. In other embodiments, the portion of the working head 20 in contact with the human body may also be in other shapes, for example, the surface of the working head 20 in contact with the human body is set as an arc surface, and a convexity or a concave is set on the surface. The first pressure sensor 3 is preferably a sheet-like thin film sensor, such as a piezoelectric film sensor.

[0075] In some embodiments, Figure 3 As shown, the massage head 2 includes a first housing component 22 and a second housing component 23. The first housing component 22 is connected to the working head 20 and includes a first housing 220 with an opening at one end and a first pressure cover 221 connected to the opening end of the first housing 220. A cavity for accommodating the vibration device 21 is formed between the first housing 220 and the first pressure cover 221. The second housing component 23 includes a second housing 230 with an opening at one end and a second pressure cover 231 connected to the opening end of the second housing 230. A cavity for accommodating the first housing component 22 is formed between the second housing 230 and the second pressure cover 231. The first pressure sensor 3 and the first housing component 22 are arranged along the vibration direction of the working head 20 and clamped between the first housing component 22 and the second housing component 23. Figure 3 In the embodiment, the first pressure sensor 3 is clamped between the first bottom plate 2200 of the first housing 220 and the second bottom plate 2300 of the second housing 230. When the working head 20 is pressurized, the force exerted by the skin on the working head 20 is transmitted to the first housing component 22 through the vibration device 21, and then transmitted to the first pressure sensor 3 by the first housing component 22, so that the first pressure sensor 3 detects the pressure value. The first pressure sensor 3 is preferably a sheet-like thin film sensor, such as a piezoelectric film sensor.

[0076] In some embodiments, a first pressure sensor 3 is provided in the working head 20 and in the second housing component 23 , and the pressure of the working head 20 on the skin is comprehensively judged by the pressure values ​​detected by the two first pressure sensors 3 .

[0077] like Figures 3 to 7As shown, the vibration device 21 includes an outer bracket 210 disposed in the first housing component 22 and a stator component 211 and a vibration component 212 both disposed in the outer bracket 210. The outer bracket 210 is fixedly connected to the first housing component 22. Preferably, it is clamped and fixed between the first housing 220 and the first gland 221. The vibration component 212 is movably disposed in the outer bracket 210 and can vibrate along the vibration axis under the drive of the stator component 211. The direction of the vibration axis is the vibration direction A. The connecting member 24 is slidably matched with the first housing component 22. Specifically, a guide hole 2210 is provided on the first gland 221. The connecting member 24 is penetrated in the guide hole 2210 and adapted to the guide hole 2210, so that it can make a linear motion along the guide hole 2210. The connecting member 24 is connected between the vibration component 212 and the working head 20. After the vibration component 212 vibrates, the working head 20 can be driven to make a linear vibration along the vibration direction A through the connecting member 24.

[0078] The working head 20 and the connecting member 24 are preferably detachably connected, such as Figure 3 , Figure 8 and Fig. 9 As shown, the working head 20 is provided with a plate-shaped body 200 and a connecting portion 201 protruding from the body 200, and a mounting hole 240 is provided on the end surface of the connecting member 24 facing the working head 20, and the connecting portion 201 is tightly matched with the mounting hole 240 and can be pulled out of the mounting hole 240 under the action of an external force. The connecting portion 201 can be made of, for example, an elastic material or an elastic layer can be provided on the outside, and the elastic material and the elastic layer can be made of, for example, silicone, rubber, etc.

[0079] As a preferred embodiment, the vibration component 212 is connected to the outer bracket 210 through the spring piece 213 and can be reset under the elastic force of the spring piece 213. Figure 5 and Figure 6 As shown, in some embodiments, the two ends of the outer bracket 210 are open, and the vibration device 21 includes two springs 213 respectively connected to the two open ends of the outer bracket 210, and the springs 213 include an outer ring body 2130 connected to the outer bracket 210, an inner plate 2131 arranged in the outer ring body 2130, and an elastic arm 2132 connected between the outer ring body 2130 and the inner plate 2131. The two ends of the vibration component 212 are respectively connected to the inner plates 2131 of the two springs 213. When the vibration component 212 vibrates, the inner plate 2131 vibrates with the vibration component 212, and the elastic arm 2132 is elastically deformed, thereby generating an elastic force that drives the vibration component 212 to reset. By providing two springs 213 located at the two ends of the vibration component 212, the force of the vibration component 212 can be made more stable. In other embodiments, the vibration component 212 can also be provided with a spring 213 at only one end.

[0080] The first gland 221 is provided with a first abutment 2211 protruding toward the vibration device 21, the first bottom plate 2200 of the first housing 220 is provided with a second abutment 2201 protruding, and both ends of the vibration device 21 along the vibration direction are clamped between the first abutment 2211 and the second abutment 2201. Figure 3 , Figure 7 and Fig.10 As shown, the first abutment 2211 and the second abutment 2201 abut against the outer ring bodies 2130 of the two spring sheets 213, respectively. Preferably, the first abutment 2211 and the second abutment 2201 do not contact the elastic arms 2132 to avoid interfering with the deformation of the elastic arms 2132. The shapes of the first abutment 2211 and the second abutment 2201 are not limited, for example, they can be block-shaped or ring-shaped.

[0081] The vibration component 212 and the inner plate 2131 of the spring 213 may be directly connected or indirectly connected via the spacer 2122. Figure 6 As shown, in this embodiment, both ends of the vibration component 212 are connected to the inner plate 2131 through a spacer 2122. The spacer 2122 is preferably arranged not to be opposite to the elastic arm 2132. In this way, there is a larger spacing space between the vibration component 212 and the elastic arm 2132, which can prevent the vibration component 212 from colliding or contacting the elastic arm 2132.

[0082] As a preferred embodiment, the vibration component 212 includes two magnetic conductive plates 2120 arranged along the vibration direction A and a first magnet 2121 connected between the two magnetic conductive plates 2120, and the first magnet 2121 is magnetized along the vibration direction A. The stator component 211 includes a coil 2110 surrounding the outside of the magnetic conductive plate 2120, and the coil 2110 is fixedly connected to the outer bracket 210. The stator component 211 may include only one coil 2110, which surrounds the outside of one of the two magnetic conductive plates 2120, or may include two coils 2110, which surround the outer periphery of the two magnetic conductive plates 2120, respectively, and the axial direction of the coil 2110 is parallel to the vibration direction A. Further preferably, the vibration component 212 also includes two second magnets 2123, and the two second magnets 2123 are respectively connected to the outer surfaces of the two magnetic conductive plates 2120 away from the first magnet 2121. The second magnet 2123 and the first magnet 2121 are arranged opposite to each other with the same poles, which can increase the magnetic flux lines penetrating from the magnetic plate 2120 into the coil 2110, thereby increasing the driving force. When an alternating current is passed through the coil 2110, a changing magnetic force is generated between it and the vibration component 212, thereby driving the vibration component 212 to vibrate.

[0083] It is understandable that the structures of the vibration component 212 and the stator component 211 are not limited to the above structures, for example, they may also be a moving coil structure or other structures.

[0084] like Figure 1 As shown, the position adjustment device 5 includes two stoppers 50 and two sets of sliding components 51 respectively connected to the two stoppers 50 in a sliding manner. The two stoppers 50 are connected to the neck-worn bracket 1, and the two stoppers 50 are arranged at intervals. A rear bracket 52 is arranged between the two stoppers 50. The position of the sliding component 51 on the stoppers 50 is adjustable, and the two ends of the sheet body 4 are respectively connected to the two sets of sliding components 51 and are arranged on the inner side of the neck-worn bracket 1.

[0085] When the sliding assembly 51 changes position on the limiter 50, the sheet 4 is also driven to move, so that the distance between the sheet 4 and the working head 20 of the neck bracket 1 changes, and the area enclosed by the throat massager also changes. In this way, the throat massager can be adapted to users with different neck sizes by moving the sheet 4. At the same time, adjusting the sliding assembly 51 does not affect the size change of the neck bracket 1, so it will not affect the cables set in the neck bracket 1. Further, since the sheet 4 and the working head 20 can be clamped on the front and back sides of the neck, after the distance between the sheet 4 and the working head 20 is reduced, the clamping force of the sheet 4 and the working head 20 on the neck will increase. Conversely, after the distance between the sheet 4 and the working head 20 is increased, the clamping force of the sheet 4 and the working head 20 on the neck will decrease. Therefore, the pressure of the working head 20 on the skin can be adjusted by adjusting the position of the sheet 4.

[0086] like Fig.11 and Fig.12 As shown, as a preferred embodiment, the sliding assembly 51 includes a sliding sleeve 510 slidably matched with the limiting member 50, and a button 511 rotatably connected to the sliding sleeve 510. The button 511 is configured to have a first position engaged with the limiting member 50 and a second position disengaged from the limiting member 50. When the button 511 is in the second position, the sliding sleeve 510 can move relative to the limiting member 50, and the position of the sheet body 4 can be adjusted by adjusting the position of the sliding sleeve 510 on the sliding assembly 51; when the button 511 is switched to the first position, the sliding sleeve 510 is engaged and fixed with the limiting member 50 by the button 511, which can prevent the sliding assembly 51 from moving, thereby ensuring the stability of the throat massager when worn.

[0087] like Fig.11 and Fig.12As shown, the outer surface of the limiter 50 is provided with a plurality of grooves 500 arranged at intervals. Preferably, the intervals between two adjacent grooves 500 are equal, that is, the grooves 500 are arranged at equal intervals. The button 511 is provided with a clamping portion 5110 protruding toward the side where the groove 500 is located. When the button 511 is in the first position, the button 511 is inserted into the groove 500 through the clamping portion 5110 to achieve clamping with the limiter 50. The clamping portion 5110 is limited by the groove 500 to prevent the sliding sleeve 510 from moving along the limiter 50. Preferably, when the clamping portion 5110 cooperates with the groove 500, both sides of the clamping portion 5110 along the thickness direction abut against the groove wall of the groove 400 to more comprehensively limit the freedom of the button 511 along the circumferential direction of the limiter 50.

[0088] like Fig.11 and Fig.12 As shown, in some embodiments, the sliding assembly 51 includes a rotating shaft 512 connected between the sliding sleeve 510 and the button 511 and a first elastic member 513 elastically abutting between the sliding sleeve 510 and the button 511. When the button 511 is not subjected to an external force (such as the pressing force of a finger), the button 511 is kept in the first position under the elastic force of the first elastic member 513. When the button 511 is subjected to an external force, the button 511 rotates with the rotating shaft 512 as a fulcrum, so that the end of the clamping portion 5110 of the button 511 is tilted, and the clamping portion 5110 leaves the groove 500 of the limiting member 50 and switches to the second position. At this time, the sliding sleeve 510 can move along the limiting member 50, thereby adjusting the position of the sheet 4. The first elastic member 513 is preferably a spring. It is understandable that the first elastic member 513 and the clamping portion 5110 can be respectively arranged on both sides of the rotating shaft 512, or can be arranged on the same side of the rotating shaft 512. When they are on the same side, the first elastic member 513 applies a pulling force to the button 511 toward the side where the limiting member 50 is located.

[0089] In some embodiments, Fig.11 and Fig.12 As shown, the outer peripheral surface 501 of the limiter 50 is provided with a plurality of protrusions 502 arranged at intervals, and the groove 500 is formed between two adjacent protrusions 502. Preferably, each protrusion 502 is arranged at equal intervals. The outer peripheral surface 501 is the surface of the limiter 50 away from the neck. The limiter 50 is sleeved on the neck-mounted bracket 1 and is relatively fixed to the neck-mounted bracket 1. The two limiters 50 are respectively arranged on both sides of the neck-mounted bracket 1; the sliding sleeve 510 is sleeved on the limiter 50 and can slide along the limiter 50. The button 511 is arranged relative to the outer peripheral surface 501 of the limiter 50. The button 511 is arranged on the outer peripheral surface 501 of the limiter 50, which is more convenient for the user to operate the button.

[0090] In some embodiments, Fig.13As shown, the groove 500 can also be configured to be formed by being recessed from the outer peripheral surface 501 of the limiting member 50 .

[0091] As a preferred embodiment, the sheet 4 is entirely or partially made of elastic material to adaptively extend or shorten when the position of the sliding sleeve 510 changes. Preferably, the elastic material is an elastic band. Fig.14 , the sheet 4 is made entirely of elastic bands. Fig.15 The sheet 4 includes a first portion 41 located in the middle and second portions 42 located on both sides. The first portion 41 is made of elastic material (such as elastic band), and the second portion 42 is made of other materials (such as leather).

[0092] As a preferred embodiment, the sheet body 4 is detachably connected to the sliding assembly 51, so that the sheet body 4 can be easily replaced and cleaned. Fig.11 and Fig.14 As shown, in some embodiments, the sliding assembly 51 further includes a first rod 515 connected to the sliding sleeve 510 and a first protrusion 514 connected to the first rod 515, the first rod 515 is connected to the surface of the sliding sleeve 510 facing the neck side, and is penetrated on the sheet 4, and the first protrusion 514 is located on the side of the sheet 4 facing away from the sliding sleeve 510, and is used to prevent the sheet 4 from being separated from the first rod 515. For example, a hole 40 with a diameter smaller than the first protrusion 514 can be opened on the sheet 4, and the first protrusion 514 passes through the hole 40, so that the first protrusion 514 can limit the sheet 4 from being separated from the first rod 515, but under a certain external force, the hole 40 can be elastically deformed and separated from the first protrusion 514, so as to achieve disassembly. For another example, a slit can be opened on the sheet 4, and the position of the sheet 4 can be limited by inserting the first protrusion 514 into the slit.

[0093] As a preferred embodiment, the throat massager also includes an angle adjustment device connected between the massage head and the neck bracket 1, the angle adjustment device includes an angle adjustment component 6, the angle adjustment component 6 is used to adjust the angle of the massage head 2, the angle adjustment component 6 has a rotation axis 6a, and the massage head 2 can rotate around the rotation axis 6a to adjust the massage position of the massage head 2 on the human body and improve the accuracy of the massage. It can be understood that by adjusting the position of the massage head 2, the massage head 2 can massage the required position, thereby improving the comfort and effect of use.

[0094] In some embodiments, Figure 1 and 16As shown, the angle adjustment device includes an angle adjustment component 6, the rotation axis 6a of the angle adjustment component 6 is horizontally arranged, and the massage head 2 can rotate around the rotation axis 6a in the vertical direction. The horizontal arrangement of the rotation axis 6a refers to the state of the rotation axis 6a when the neck-mounted bracket 1 is in a horizontal state. It can be seen from the figure that when the neck-mounted bracket 1 is in a horizontal state, its width direction B is perpendicular to the horizontal plane, and the rotation axis 6a is perpendicular to the width direction B of the neck-mounted bracket 1.

[0095] In some embodiments, the angle adjustment device includes two angle adjustment components 6, wherein the rotation axis 6a of one angle adjustment component 6 is arranged horizontally, and the rotation axis 6a of the other angle adjustment component 6 is arranged vertically. Fig.17 As shown, Fig.17 In the illustrated embodiment, the rotation axis 6a of the angle adjustment assembly 6 relatively close to the massage head 2 is horizontally arranged, and the rotation axis 6a is perpendicular to the width direction B of the neck-mounted bracket 1. The rotation axis 6a of the angle adjustment assembly 6 relatively far from the massage head 2 is vertically arranged, and the rotation axis 6a is parallel to the width direction B of the neck-mounted bracket 1. In this way, the massage head 2 can rotate both along the horizontal axis and around the vertical axis, and its position change is more diverse, which is more conducive to adjusting to a suitable working position. At the same time, the position of the massage head 2 will affect its pressure on the skin. Therefore, by adjusting the angle of the massage head 2, the pressure of the working head 20 on the skin can also be adjusted. Similarly, the state of the rotation axis 6a (the present embodiment refers to the horizontal setting and the vertical setting) refers to the state of the rotation axis 6a when the neck-mounted bracket 1 is in a horizontal state. It can be understood that by coordinating the two methods of rotating the working head 20 and adjusting the position of the sheet 4, the working head 20 can apply appropriate pressing force at the appropriate position. For example, when the working head 20 is rotated toward the side where the neck is located, the pressure on the skin will increase. At this time, the sheet 4 can be moved back appropriately to reduce the pressure of the working head 20 on the skin.

[0096] It is understandable that the angle adjustment device may further include more angle adjustment components 6, and the rotation axis 6a of the angle adjustment component 6 does not necessarily have to be arranged horizontally or vertically, for example, it may also be arranged inclined to the horizontal plane or the vertical plane. Preferably, the angle adjustment device includes two angle adjustment components 6, and the rotation axes 6a of the two angle adjustment components 6 are perpendicular to each other.

[0097] As a preferred embodiment, the angle adjustment assembly 6 includes a first shell 60 , a second shell 61 , a locking member 62 , a pressing member 63 and a second elastic member 64 .

[0098] The first housing 60 has a first opening end 600. Figures 18 to 21As shown, it includes a first plate body 602 and a first annular side plate 603 extending from the outer edge of the plate body 602 to one side, and the first opening end 600 and the first plate body 602 are located at both ends of the first shell 60. The first shell 60 also includes a first inner gear ring 601 provided on the inner surface of the first annular side plate 603. It can be understood that the first inner gear ring 601 includes a plurality of teeth arranged at intervals.

[0099] The second housing 61 is disposed at the first open end 600. The second housing 61 includes a base plate 611 and a second annular side plate 612 surrounding the outside of the base plate 611. The end of the second annular side plate 612 facing the first housing 60 is the second open end 613 of the second housing 61. The second open end 613 is butted against the first open end 600. Preferably, the end faces of the two are in contact. The second housing 61 also includes a second inner gear ring 610 disposed on the inner surface of the second annular side plate 612. It can be understood that the second inner gear ring 610 includes a plurality of teeth arranged at intervals. Preferably, the teeth of the second inner gear ring 610 have the same cross-sectional shape as the teeth of the first inner gear ring 601.

[0100] The second housing 61 is rotatably connected to the first housing 60. As a preferred embodiment, Fig.16 and Fig.21 As shown, the angle adjustment assembly 6 includes a second rod portion 650 connected to the first housing 60 and a second protrusion 651 provided on the second rod portion 650. The second rod portion 650 is preferably detachably connected to the first housing 60, for example, it can be a threaded connection. The base plate 611 is slidably matched with the second rod portion 650. Specifically, the second rod portion 650 is penetrated on the base plate 611 so that the base plate 611 can move along the second rod portion 650. The second protrusion 651 protrudes outward from the side of the second rod portion 650, and is located on the side of the base plate 611 facing away from the first housing 60, and is used to prevent the base plate 611 from being separated from the second rod portion 650. The second rod portion 650 and the second protrusion 651 are preferably integrally formed, and the whole formed by the second rod portion 650 and the second protrusion 651 can be, for example, a bolt, or the second rod portion 650 and the second protrusion 651 are preferably part of a bolt.

[0101] like Fig.16 and Fig. 22 As shown, the locking member 62 is slidably connected between the first housing 60 and the second housing 61, and its outer surface is provided with an outer gear ring 622 that meshes with the first inner gear ring 601 and the second inner gear ring 610, and the outer gear ring 622 is provided with at least one tooth that matches the first inner gear ring 601 and the second inner gear ring 610. The locking member 62 is sleeved on the second rod portion 650 and can slide along the second rod portion 650 to change its position on the first inner gear ring 601 and the second inner gear ring 610. For example, the locking member 62 has a locking position that meshes with the first inner gear ring 601 and the second inner gear ring 610 at the same time (refer to Fig.23) and completely moved to the disengagement position on the first inner gear ring 601 and not in contact with the second inner gear ring 610 (reference Fig.24 ). In the locked position, since the locking member 62 is meshed with the first inner gear ring 601 and the second inner gear ring 610 at the same time, the first housing 60 and the second housing 61 cannot rotate around the axis of the second rod 650 (i.e., the rotation axis 6a), while in the disengaged position, the first housing 60 and the second housing 61 are not limited by the locking member 62, so they can rotate around the second rod 650 to adjust the position. After the angle adjustment is completed, the locking member 62 is switched to the locked position to maintain the angle between the first housing 60 and the second housing 61.

[0102] Obviously, when one of the first shell 60 and the second shell 61 is connected to the massage head 2 and the other is connected to the neck-mounted bracket 1, the angle of the massage head 2 relative to the neck-mounted bracket 1 can be adjusted by adjusting the angles of the two shells.

[0103] Preferably, the locking position is the initial position of the locking member 62, which is maintained by the second elastic member 64, and after the locking member 62 is out of the initial position, the second elastic member 64 can provide elastic force to drive the locking member 62 back to the initial position. Fig.23 The second elastic member 64 elastically abuts between the locking member 62 and the first shell 60. Specifically, the second elastic member 64 is a spring, which surrounds the outside of the second rod portion 650, one end of which abuts against the first plate body 602 of the first shell 60, and the other end abuts against the locking member 62. The elastic member 62 is in a compressed state, and the locking member 62 is kept in a locked position by elastic force.

[0104] The pressing member 63 is used to drive the locking member 62 to move to the disengaged position under the action of external force. Fig.24 As shown, the pressing member 63 is slidably engaged with the second housing 61. Specifically, the pressing member 63 includes a connecting arm 620 that passes through the base plate 611 and abuts against the locking member 62. The connecting arm 620 is provided with a hook portion 621 that protrudes outward along its side. The hook portion 621 can be provided on the outer surface of the connecting arm 620 that faces away from the second rod portion 650, or on the inner surface of the connecting arm 620 that faces the second rod portion 650. The hook portion 621 can abut against the surface of the base plate 611 that faces the first housing 60 to prevent the pressing member 63 from being separated from the base plate 611. A guide hole 6110 is provided on the base plate 611 for the connecting arm 620 to pass through. The pressing member 63 is slidably engaged with the second housing 61 through the engagement of the connecting arm 620 with the guide hole 6110.

[0105] Pressing the pressing member 63 can drive the locking member 62 to move toward the side where the first housing 60 is located, so that the locking member 62 is disengaged from the second inner gear ring 610 and completely moves to the first inner gear ring 601, that is, moves to the disengaged position. After releasing the pressing member 63, the pressing member 63 returns to the locked position under the elastic force of the second elastic member 64, and the relative position of the first housing 60 and the second housing 61 is automatically locked, making the use of the throat massager more convenient.

[0106] like Figure 1 and Fig.16 As shown, when the angle adjustment device includes only one angle adjustment component, the angle adjustment device also includes a first connecting element 66 connected between the second shell 230 and the first shell 60 and a second connecting element 67 connected between the end 12 of the neck-mounted bracket 1 and the second shell 61. Preferably, the second shell 230, the first connecting element 66 and the first shell 60 are integrally formed, and the second shell 61 and the second connecting element 67 are integrally formed.

[0107] like Fig.17 As shown, when the angle adjustment device includes two angle adjustment components 6, the above-mentioned second connecting element 67 is connected between the second shells 61 of the two angle adjustment components 6, and a third connecting element 68 is arranged on the first shell 60 of the angle adjustment component 6 which is relatively far away from the massage head 2, and the third connecting element 68 is connected to the end 12 of the neck-mounted bracket 1.

[0108] It can be understood that the structure of the above-mentioned angle adjustment component 6 is only an example, and the structure of the angle adjustment component 6 is not limited thereto. Any structure used to adjust the angle in the prior art can be applied here as long as there is no conflict.

[0109] In some embodiments, Fig.25As shown, the laryngeal massager includes a controller 8, which is electrically connected to the first pressure sensor 3 and the vibration device 21, and can control the vibration of the vibration device 21. The control method can be, for example, key control, voice control, touch control, etc. The controller 8 can control the parameters such as the frequency and amplitude of the vibration device 21. The signal detected by the first pressure sensor 3 can be transmitted to the controller 8, which is analyzed and processed by the controller 8. A suitable pressure range can be pre-stored in the controller 8. The pressure range can be, for example, the most comfortable pressure range obtained by the user after use, or the most effective pressure range for treating or relieving laryngeal discomfort obtained after clinical testing. When the pressure value detected is within the pressure range, it indicates that the pressure is appropriate, and the laryngeal massager can work normally at this time. When the pressure value detected is too large or too small, it indicates that the pressure of the working head 20 on the skin is too large or too small. At this time, the controller 8 can issue a warning to remind the user to adjust the pressure. For example, a warning can be issued in the form of sound and / or light (for example, a speaker and LED light are installed), or the vibration device 21 can be controlled to stop vibrating to allow the user to check.

[0110] In some embodiments, the angle adjustment assembly 6 can also be electric, using the motor 69 as a power source to drive the first shell 60 and the second shell 61 to rotate relative to each other, thereby adjusting the angle of the massage head 2. Fig.26 The angle adjustment assembly 6 includes a first shell 60 connected to the massage head 2, a second shell 61 rotatably connected to the first shell 60, and a motor 69 connected between the first shell 60 and the second shell 61. One of the motor body 690 and the motor shaft 691 of the motor 69 is connected to the first shell 60, and the other is connected to the second shell 61. In this way, when the motor shaft 691 rotates, the first shell 60 and the second shell 61 can rotate relative to each other. The second shell 61 is connected to the neck bracket 1, which can be directly connected or indirectly connected through other components. Fig. 27 As shown, the motor 69 is electrically connected to the controller 8, and the angle can be adjusted by controlling the motor to rotate forward and reversely through the controller 8. The optimal working position of the massage head 2 can be preset in the controller 8. When the user wears the throat massager, the throat massager can automatically adjust the massage head 2 to the corresponding angle according to the preset parameters. Furthermore, different users can store different optimal working position parameters accordingly. When using, they can select the parameters corresponding to their own identity information for massage, which is more convenient to use.

[0111] In some embodiments, the position of the sheet 4 can be adjusted without manual adjustment, for example, by moving the sheet 4 pneumatically or electrically. Fig.28As shown, the position adjustment device 5 includes an airbag 53 connected to a rear bracket 52 located in the middle of the neck-mounted bracket 1 and an air pump 54 connected to the airbag 53. The airbag 53 is located in the middle of the neck-mounted bracket 1 on the side facing the human body. The sheet 4 can be a part of the airbag 53 (for example, the part of the airbag 53 that contacts the human body is the sheet 4), or it can be an independent part connected to the airbag 53 (for example, the sheet 4 is attached to the surface of the airbag 53 facing the human body). The air pump 54 is used to inflate and deflate the airbag 53. Fig.29 , which is electrically connected to the controller 8. When the airbag 53 is inflated, the sheet 4 moves toward the side where the working head 20 is located. Conversely, when the airbag 53 is deflated, the sheet 4 moves away from the working head 20, thereby realizing automatic adjustment of the position of the sheet 4. By setting the sheet 4 in a form that can automatically adjust the position, the controller 8 can automatically control the inflation and deflation of the airbag 53 according to the pressure value detected by the first pressure sensor 3, so that the pressure value reaches a suitable range.

[0112] In some embodiments, the sheet 4 and the airbag 53 are independently arranged and not connected, the sheet 4 is located on the side of the airbag 53 facing the working head 20, and the airbag 53 and the structure of manually adjusting the sheet 4 described above can exist at the same time to improve the support force of the sheet 4 on the neck. For example, after the sheet 4 is adjusted to a suitable size by the sliding component 51, at this time, if the sheet 4 is in a suspended state, it is easy to be deformed by force, and may become loose during use. By inflating the airbag 53 to make it press against the sheet 4, the support force of the sheet 4 on the neck can be improved, and the stability and comfort of wearing can be improved.

[0113] In some embodiments, the throat massager further includes a second pressure sensor 7, which is disposed on a part of the throat massager that contacts the human body when the throat massager is worn, for example, attached to the inner surface or outer surface of the part, and is used to detect the pressure value of the part, thereby obtaining the clamping force of the throat massager on the human body, and the comfort of the throat massager when worn can be determined based on the clamping force. It is understandable that the second pressure sensor 7 detects a different position from the first pressure sensor 3, and is not used to detect the pressure of the working head 20 on the skin.

[0114] Optionally, the second pressure sensor 7 is arranged at a position corresponding to the side of the human neck when the throat massager is worn, preferably at the front half of the throat massager, so as to more reliably judge the clamping force of the throat massager on the human body. The front half refers to the part of the throat massager located on the side of the midpoint 1a of the neck-worn bracket 1 close to the massage head 2. The outer end points of the two end parts 12 of the neck-worn bracket 1 in the natural state have an end connection line 1b, and a midline 1c is formed between the outer midpoint of the rear end of the neck-worn bracket 1 and the midpoint of the end connection line 1b. The midpoint 1a passes through the midpoint of the midline 1c and is perpendicular to the midline 1c.

[0115] Fig.28 In the illustrated embodiment, the second pressure sensor 7 is disposed on the surface of the third connecting element 68 facing the human body, and is capable of detecting the squeezing force of the third connecting element 68 on the human body. Optionally, the third connecting element 68 is completely located in the front half of the throat massager. In other embodiments, the second pressure sensor 7 may also be disposed in other locations. Preferably, it is disposed at the location where the neck bracket 1 and / or the angle adjustment device contacts the human body when worn, and is less affected by the vibration of the vibration device 21. Fig.29 The second pressure sensor 7 is also electrically connected to the controller 8. The controller 8 can also pre-store a suitable pressure range corresponding to the second pressure sensor 7. When it exceeds the range, it can automatically (for example, control the rotation of the motor, control the inflation and deflation of the airbag) or remind the user to manually adjust the sheet 4 and / or the angle adjustment device to adjust the value to a suitable range, thereby improving the use effect and comfort of the throat massager.

[0116] It can be understood that the clamping force of the neck mount bracket 1 on the neck can be adjusted by adjusting the position of the sheet 4 by adjusting the sliding assembly 51. When the sheet 4 moves toward the side where the massage head 2 is located, the sheet 4 is pulled apart and will apply a pulling force to both sides of the neck mount bracket 1, thereby causing the throat massager to clamp the human body. Conversely, when the sheet 4 moves away from the massage head 2, the clamping force of the throat massager on the neck will gradually decrease.

[0117] The above are only specific implementations of the present invention, and any improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
