Shoulder and neck massage instrument

Abstract

According to the shoulder and neck massage instrument, the air bag of the massage assembly drives the first massage piece and the second massage piece to move at the same time in an inflation expansion mode, and the first massage piece and the second massage piece are suitable for moving along with deflation contraction of the air bag. Therefore, the first massage head and the second massage head are close to each other or far away from each other to achieve kneading massage. The time period that the first massage head and the second massage head get close to each other and then get away from each other to complete one-time reciprocating motion is a massage period, and the maximum inflation volumes of the air inflated into the air bag in at least two massage periods are different. Therefore, the minimum distances between the first massage head and the second massage head are different when the first massage head and the second massage head get close to each other in at least two massage periods. Thus, the movement range of the first massage piece and the second massage piece can be adjusted by adjusting the maximum inflation volume of the air bag, the minimum distance between the first massage head and the second massage head can be adjusted so as to adjust the clamping and pinching strength, and the massage manipulation of the shoulder and neck massage instrument can be enriched.

Technical Field

[0001] This application relates to the technical field of massage instruments, and particularly to a neck and shoulder massager. Background Art

[0002] Currently, consumers widely use neck and shoulder massagers to massage the neck and shoulders to relieve fatigue in these areas. The neck and shoulder massagers in related technologies can imitate the kneading massage of human hands, but their pinching force is fixed and cannot meet the usage requirements of people who need different pinching forces. Summary of the Utility Model

[0003] Embodiments of the present utility model propose a neck and shoulder massager to improve at least one of the above technical problems.

[0004] Embodiments of the present utility model achieve the above object through the following technical solutions.

[0005] Embodiments of the present utility model provide a neck and shoulder massager, which includes a massage component and an airbag. The massage component includes a first massage member having a first massage head and a second massage member having a second massage head. The airbag drives the first massage member and the second massage member to move simultaneously by inflating and expanding. The first massage member and the second massage member are adapted to move as the airbag deflates and contracts, so that when the airbag inflates and expands or deflates and contracts, the first massage head and the second massage head approach or move away from each other to achieve kneading massage; the time period when the first massage head and the second massage head approach each other and then move away from each other to complete a reciprocating motion is defined as a massage cycle. The maximum inflation volume of the airbag filled with gas is different in at least two massage cycles, so that the minimum distance between the first massage head and the second massage head when they approach each other is different in at least two massage cycles.

[0006] In some embodiments, a plurality of sequentially performed massage cycles constitute a massage technique. In a massage technique, the maximum inflation volume of the airbag filled with gas is different in at least two massage cycles.

[0007] In some embodiments, in a massage technique, two massage cycles are defined as the first massage cycle and the second massage cycle respectively. The first massage cycle is performed before the second massage cycle, and the maximum inflation volume of the airbag filled with gas in the first massage cycle is less than that in the second massage cycle.

[0008] In some embodiments, in a massage technique, as a plurality of massage cycles are sequentially performed, the maximum inflation volume of the airbag filled with gas in the plurality of massage cycles gradually increases.

[0009] In some embodiments, in a massage technique, there is a maximum inflation volume among the maximum inflation volumes of the airbag being inflated with gas within multiple massage cycles; the neck and shoulder massager has multiple massage techniques, and the maximum inflation volumes of the airbag in at least two massage techniques are different.

[0010] In some embodiments, the neck and shoulder massager includes an air pump, and the air pump is connected to the airbag to be adapted to inflate the airbag with gas.

[0011] In some embodiments, the neck and shoulder massager includes a controller connected to the air pump, and the controller is configured to receive user instructions to control the air pump to inflate the airbag with a set amount of gas.

[0012] In some embodiments, the controller is configured to control the air pump to inflate the airbag with a set amount of gas based on the degree of muscle fatigue.

[0013] In some embodiments, the neck and shoulder massager includes a transmission member connected between a first massage member and a second massage member. The first massage member is adapted to reciprocally rotate about a first axis, and the transmission member reciprocally rotates about a second axis in a direction consistent with the rotation direction of the first massage member under the drive of the first massage member, and the second massage member reciprocally yaws under the drive of the transmission member.

[0014] In some embodiments, the airbag has a non-inflated state in which the internal gas is completely released and an inflated state in which the internal inflation volume reaches the maximum. When the airbag changes from the non-inflated state to the inflated state, the angle of rotation of the first massage member about the first axis is a1, where 0 < a1 ≤ 80°.

[0015] In some embodiments, the airbag has a non-inflated state in which the internal gas is completely released and an inflated state in which the internal inflation volume reaches the maximum. When the airbag changes from the non-inflated state to the inflated state, the angle of rotation of the transmission member about the second axis under the drive of the first massage member is a2, where 0 < a2 ≤ 360°, and the transmission member drives the second massage member to swing at least from the position where the second massage head is farthest from the first massage head to the position where the second massage head is closest to the first massage head.

[0016] In some embodiments, the airbag has a non-inflated state in which the internal gas is completely released and an inflated state in which the internal inflation volume reaches the maximum. When the airbag changes from the non-inflated state to the inflated state, the angle of rotation of the first massage member about the first axis is a1, and the angle of rotation of the transmission member about the second axis under the drive of the first massage member is a2, then a1 < a2.

[0017] In some embodiments, the neck and shoulder massager includes a gear set, and the first massage member drives the transmission member to rotate through the gear set; the gear set includes a first gear and a second gear. The diameter of the second gear is smaller than that of the first gear, and the second gear meshes with the first gear directly or indirectly. The first gear is connected to the first massage member, and the second gear is connected to the transmission member.

[0018] In some embodiments, the gear ratio of the gear set is i, i>1.

[0019] In some embodiments, the first gear rotates around the first axis, the second gear rotates around the second axis, the teeth of the first gear are arranged around the second axis, and mesh with the second gear on the side of the second axis away from the first axis.

[0020] In some embodiments, the first massage member is provided with an avoidance opening, and the second shaft is passed through the avoidance opening.

[0021] In some embodiments, the groove wall of the avoidance passage is provided with saw teeth to form a first gear, and the second gear is at least partially in the avoidance passage to mesh with the first gear.

[0022] In some embodiments, a mounting groove is provided on the outer wall surface of the transmission member and extends in a direction surrounding the second axis, and the extension direction of the mounting groove defines an extension plane, which is inclined relative to the first axis; the second massage member is sleeved on the transmission member in the mounting groove, and the portion of the second massage member accommodated in the mounting groove matches the mounting groove, and can rotate relative to the transmission member along the extension direction of the mounting groove as the transmission member rotates around the second axis.

[0023] In some embodiments, the shoulder and neck massager includes a base, a first massage element is rotatably mounted on the base around a first axis, and a second massage element is slidably connected to the base along an extension direction of a second axis.

[0024] The shoulder and neck massager provided by the utility model embodiment has an airbag that drives the first massage piece and the second massage piece to move at the same time by means of inflation and expansion, and the first massage piece and the second massage piece are suitable for moving with the deflation and contraction of the airbag, so that when the airbag is inflated or deflated, the first massage head and the second massage head are close to or away from each other to achieve kneading massage. In this way, the airbag can output a driving force by means of inflation and expansion so that both the first massage piece and the second massage piece can move, and the first massage piece and the second massage piece are suitable for moving with the deflation and contraction of the airbag, so that when the airbag is inflated or deflated, the first massage piece and the second massage piece can move, so that the first massage head and the second massage head can act on the massage part to achieve kneading massage. The first massage head and the second massage head can also cooperate to clamp the massage part together when approaching each other to achieve a pinching massage imitating human hands, which helps to improve the user experience. Since the airbag has a certain elasticity, the first massage head and the second massage head can rebound adaptively when performing pinching massage, which helps to achieve soft massage instead of hard massage.

[0025] The time period for the first massage head and the second massage head to approach and then move away from each other to complete a reciprocating motion is one massage cycle. The maximum inflation volume of the airbag when it is inflated is different in at least two massage cycles, so that the minimum distance between the first massage head and the second massage head when they approach each other is different in at least two massage cycles. In this way, by adjusting the maximum inflation volume of the airbag, the movement amplitude of the first massage member and the second massage member can be adjusted, which helps to adjust the minimum distance between the first massage head and the second massage head to regulate the pinching force, helps to enrich the massage techniques of the shoulder and neck massager, helps to improve the applicability of the shoulder and neck massager to people who need different pinching forces, and also helps to improve the user experience.

These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0038] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific situations.

[0039] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0041] As certain terms are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not distinguish components by the difference in names, but by the difference in functions of the components. As used throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to"; "substantially" means that those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0042] Please refer to Figure 1 , an embodiment of the present utility model provides a neck and shoulder massager 100, which includes a massage component 11 and an airbag 12. The massage component 11 includes a first massage member 111 having a first massage head 1111 and a second massage member 112 having a second massage head 1121. Then, the neck and shoulder massager 100 can perform massage through the first massage member 111 and the second massage member 112, which helps to meet the massage needs of users.

[0043] In some embodiments, the airbag 12 drives the first massage member 111 and the second massage member 112 to move simultaneously by inflating and expanding. The first massage member 111 and the second massage member 112 are adapted to move as the airbag 12 deflates and contracts, so that when the airbag 12 inflates and expands or deflates and contracts, the first massage head 1111 and the second massage head 1121 approach or move away from each other to achieve kneading massage.

[0044] In this way, the airbag 12 can output a driving force by inflating and expanding so that both the first massage member 111 and the second massage member 112 can move. The first massage member 111 and the second massage member 112 move as the airbag 12 deflates and contracts. Thus, when the airbag 12 inflates and expands or deflates and contracts, both the first massage member 111 and the second massage member 112 can move, enabling the first massage head 1111 and the second massage head 1121 to act on the massage part respectively to achieve kneading massage. The first massage head 1111 and the second massage head 1121 can also cooperate with each other to clamp the massage part when approaching each other to achieve manual-like pinching massage, which helps to improve the user experience. Since the airbag 12 has a certain elasticity, the first massage head 1111 and the second massage head 1121 can adaptively rebound during pinching massage, which helps to achieve soft massage rather than hard massage.

[0045] In addition, the airbag 12 is light in weight, which helps to reduce the overall weight of the neck and shoulder massager 100, making the neck and shoulder massager 100 more portable and providing a better user experience for users.

[0046] Among them, the first massage member 111 and the second massage member 112 are adapted to move as the airbag 12 deflates and contracts. This may mean that the first massage member 111 is connected to the airbag 12 through a transfer structure such as a reset member, a telescopic rod, etc., so that when the airbag 12 deflates and contracts, the first massage member 111 can move with the deflation and contraction of the airbag 12 through the transfer structure, and then drive the second massage member 112 to move.

[0047] Exemplarily, the airbag 12 drives the first massage member 111 and the second massage member 112 to move simultaneously by inflating and expanding, so that the first massage head 1111 and the second massage head 1121 approach each other to press the massage part. The first massage member 111 and the second massage member 112 move with the deflation and contraction of the airbag 12 through the transfer structure, so that the first massage head 1111 and the second massage head 1121 move away from each other to release the massage part. In this way, the first massage head 1111 and the second massage head 1121 approach or move away from each other to achieve kneading massage.

[0048] Among them, the airbag 12 drives the first massage member 111 and the second massage member 112 to move simultaneously by inflating and expanding. This may mean that the first massage member 111 is connected to the second massage member 112 through a transmission structure. The airbag 12 outputs a driving force by inflating and expanding to drive the first massage member 111 to move and drives the second massage member 112 to move through the transmission structure, so that the airbag 12 drives the first massage member 111 and the second massage member 112 to move simultaneously. Or, the number of airbags 12 is two, and the two airbags 12 are respectively connected to the first massage member 111 and the second massage member 112, and output driving forces by inflating and expanding to drive the first massage member 111 and the second massage member 112 to move respectively, so that the two airbags 12 drive the first massage member 111 and the second massage member 112 to move simultaneously. Specifically, it can be set according to the actual situation. The following takes the first massage member 111 being connected to the second massage member 112 through a transmission structure, and the airbag 12 outputting a driving force by inflating and expanding to drive the first massage member 111 to move and driving the second massage member 112 to move through the transmission structure as an example for illustration.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments, the neck and shoulder massager 100 may include a transmission member 13 connected between the first massage member 111 and the second massage member 112. The first massage member 111 is adapted to reciprocally rotate about a first axis 14. The transmission member 13 reciprocally rotates about a second axis 15 in a direction consistent with the rotation direction of the first massage member 111 under the drive of the first massage member 111, and the second massage member 112 reciprocally yaws under the drive of the transmission member 13.

[0050] In this way, when the first massage member 111 moves, it can drive the second massage member 112 to move through the transmission member 13, thereby realizing the linkage between the first massage member 111 and the second massage member 112. The first massage member 111 can reciprocally rotate within the deformation stroke range of the airbag 12, and further drive the second massage member 112 to reciprocally move around the second axis 15 through the transmission of the transmission member 13, thereby realizing the reciprocating manual imitation pinching massage between the first massage member 111 and the second massage member 112.

[0051] In addition, the neck and shoulder massager 100 does not need to be provided with an additional driving mechanism to drive the second massage member 112 to act, which helps to reduce the structural complexity and weight of the neck and shoulder massager 100, helps to reduce the difficulty of the movement cooperation between the first massage member 111 and the second massage member 112, and also helps to reduce the manufacturing cost of the neck and shoulder massager 100, facilitating manufacturing.

[0052] Wherein, the transmission member 13 can be an eccentric wheel. When the airbag 12 drives the first massage member 111 to move, the first massage member 111 can drive the second massage member 112 to perform a yawing motion through the eccentric wheel, so that the first massage member 111 and the second massage member 112 can approach or move away from each other, thereby realizing the reciprocating movement between the first massage member 111 and the second massage member 112 to achieve the manual imitation pinching massage between the first massage member 111 and the second massage member 112.

[0053] In some embodiments, the time period for the first massage head 1111 and the second massage head 1121 to approach and then move away from each other to complete a reciprocating movement is one massage cycle. The maximum inflation amount of the airbag 12 is different at least in two massage cycles, so that the minimum distance between the first massage head 1111 and the second massage head 1121 when they approach each other is different at least in two massage cycles.

[0054] In this way, by adjusting the maximum inflation amount of the airbag 12, the movement amplitude of the first massage member 111 and the second massage member 112 can be adjusted, which helps to adjust the minimum distance between the first massage head 1111 and the second massage head 1121 to adjust the pinching force, helps to enrich the massage techniques of the neck and shoulder massager 100, helps to improve the applicability of the neck and shoulder massager 100 to suit people who need different pinching forces, and also helps to improve the user experience.

[0055] In some embodiments, a plurality of sequentially performed massage cycles constitute a massage technique. For example, massage cycles of two, three, four, five, six, seven or other numbers sequentially performed constitute a massage technique, which can be specifically set according to the actual situation.

[0056] In a massage technique, if the maximum inflation volume of the airbag 12 when it is inflated with gas is different in at least two massage cycles, the minimum distance between the first massage head 1111 and the second massage head 1121 can be adjusted by making the airbag 12 in a state with different maximum inflation volumes.

[0057] In this way, in a massage technique, there are at least two different minimum distances between the first massage head 1111 and the second massage head 1121, so that different pinching distances can be formed between the first massage head 1111 and the second massage head 1121 to form different pinching forces, which helps to achieve different degrees of massage on the massage part.

[0058] Exemplarily, the maximum inflation volume of the airbag 12 when it is inflated with gas can be different in two, three, four, five, six, seven or other numbers of massage cycles, and can be specifically set according to the actual situation. In this way, there are multiple different minimum distances between the first massage head 1111 and the second massage head 1121, so that different pinching distances can be formed between the first massage head 1111 and the second massage head 1121 to better form different pinching forces, which helps to achieve different degrees of massage on the massage part.

[0059] In some embodiments, in a massage technique, two massage cycles are defined as the first massage cycle and the second massage cycle respectively, the first massage cycle is carried out before the second massage cycle, and the maximum inflation volume of the airbag 12 when it is inflated with gas in the first massage cycle is less than the maximum inflation volume of the airbag 12 when it is inflated with gas in the second massage cycle.

[0060] In this way, in a massage technique, the pinching force of the neck and shoulder massager 100 in the first massage cycle is smaller, which helps to reduce the relatively large massage force of the neck and shoulder massager 100 on the user in the first massage cycle, so that the user can have an adaptation stage at the initial stage of the massage. The pinching force of the neck and shoulder massager 100 in the second massage cycle is greater than the pinching force of the neck and shoulder massager 100 in the first massage cycle, so that the pinching force in the second massage cycle is relatively large, which helps to ensure the relatively large massage force of the neck and shoulder massager 100 on the user in the second massage cycle, thus helping to ensure the massage effect of the user in the later stage of the massage. In this way, the neck and shoulder massager 100 can transition from a relatively small massage force in the first massage cycle to a relatively large massage force in the second massage cycle, so that the entire massage process of the neck and shoulder massager 100 is not too rigid, which helps to improve the user experience.

[0061] In some embodiments, in a massage technique, as multiple massage cycles are carried out in sequence, the maximum inflation volume of the airbag 12 when it is inflated with gas in multiple massage cycles gradually increases.

[0062] Thus, in a massage technique, the pinching force of the shoulder and neck massager 100 can be gradually increased, making the entire massage process of the shoulder and neck massager 100 gradual, thereby effectively relaxing the massage area and also helping to better improve the user experience.

[0063] Exemplarily, three sequentially performed massage cycles constitute a massage technique. Define the three massage cycles as the first massage cycle, the second massage cycle, and the third massage cycle. The first massage cycle is performed before the second massage cycle, and the second massage cycle is performed before the third massage cycle. In a massage technique, as the first massage cycle, the second massage cycle, and the third massage cycle are sequentially performed, the maximum inflation volume of the airbag 12 filled with gas in the first massage cycle, the second massage cycle, and the third massage cycle gradually increases.

[0064] Thus, in a massage technique, the pinching force of the shoulder and neck massager 100 can gradually increase from the first massage cycle to the second massage cycle, and the pinching force of the shoulder and neck massager 100 can gradually increase from the second massage cycle to the third massage cycle, making the entire massage process of the shoulder and neck massager 100 gradual to better improve the user experience.

[0065] In some embodiments, in a massage technique, there is a maximum inflation volume among the maximum inflation volumes of the airbag 12 filled with gas in multiple massage cycles. The shoulder and neck massager 100 has multiple massage techniques, and the maximum inflation volumes of the airbag 12 in at least two massage techniques are different.

[0066] Thus, in a massage technique, when the airbag 12 reaches the maximum inflation volume, it corresponds to the maximum pinching force of this massage technique. By making the maximum pinching forces of at least two massage techniques among multiple massage techniques different, it helps to better enrich the massage techniques of the shoulder and neck massager 100, so that the user can choose a massage technique suitable for their own tolerance or fatigue level according to their own needs for massage, to better meet the user's usage requirements.

[0067] Please refer to Figure 1 and Figure 3 , in some embodiments, the shoulder and neck massager 100 may include an air pump 19. The air pump 19 is connected to the airbag 12 to be adapted to fill the airbag 12 with gas.

[0068] Thus, the air pump 19 can inflate the airbag 12 so that the airbag 12 can be inflated and expanded or deflated and contracted through the air pump 19, thereby helping to ensure the normal operation of the airbag 12.

[0069] Among them, the air pump 19 can be configured such that the maximum inflation volume of the airbag 12 is different at least twice when inflating the airbag 12, so that the minimum distance between the first massage head 1111 and the second massage head 1121 is different at least twice when they approach each other.

[0070] In this way, the maximum inflation volume of the airbag 12 can be adjusted by the air pump 19, so that the movement range of the first massage member 111 and the second massage member 112 can be adjusted, so that the minimum distance between the first massage head 1111 and the second massage head 1121 can be adjusted, and thus the purpose of adjusting the kneading strength can be achieved. It also enables the neck and shoulder massager 100 to provide a relatively rich variety of massage techniques, which is more adaptable to people who require different kneading strengths, thereby helping to improve the user experience.

[0071] In some embodiments, the neck and shoulder massager 100 may include a controller 20 connected to the air pump 19, and the controller 20 is configured to receive a user instruction to control the air pump 19 to inflate the airbag 12 with a set amount of gas.

[0072] In this way, it helps to improve the adjustability of the massage of the neck and shoulder massager 100. The user can, according to their own needs, such as their pain tolerance or fatigue level, control the amount of gas filled into the airbag 12 by the air pump 19 by operating the controller 20, so as to adjust the state of the airbag 12 to adjust the distance between the first massage member 111 and the second massage member 112 to adjust the kneading strength, so as to better massage the massage area and help better meet the user's usage needs.

[0073] Exemplarily, when the user needs the neck and shoulder massager 100 to provide a greater kneading strength, the user can control the air pump 19 to fill a larger amount of gas into the airbag 12 within the inflation stroke range of the airbag 12 through the controller 20, so as to adjust the state of the airbag 12 to reduce the distance between the first massage member 111 and the second massage member 112 to increase the kneading strength to meet the user's needs. For another example, when the user needs the neck and shoulder massager 100 to provide a smaller kneading strength, the user can control the air pump 19 to fill a smaller amount of gas into the airbag 12 within the inflation stroke range of the airbag 12 through the controller 20, so as to adjust the state of the airbag 12 to increase the distance between the first massage member 111 and the second massage member 112 to reduce the kneading strength to meet the user's needs.

[0074] In some embodiments, the controller 20 is configured to control the air pump 19 to inflate the airbag 12 with a set amount of gas based on the degree of muscle fatigue.

[0075] In this way, the controller 20 can adjust the pinching force of the neck and shoulder massager 100 according to the muscle fatigue degree of the human body, so that the pinching force of the neck and shoulder massager 100 can adapt to the corresponding muscle fatigue degree of the user, thereby performing selective massage on the user and making the whole massage process more anthropomorphic.

[0076] Please refer to Figure 2 and Figure 4 In some embodiments, the airbag 12 has a non-inflated state in which the internal gas is completely released and an inflated state in which the internal inflation amount reaches the maximum. When the airbag 12 changes from the non-inflated state to the inflated state, the angle of rotation of the first massage member 111 around the first axis 14 is a1, where 0 < a1 ≤ 80°. In this way, the first massage member 111 can reciprocally rotate within a certain angle range, which helps to ensure that the first massage member 111 can rotate around the first axis 14 by an appropriate angle, thereby helping to ensure that there is an appropriate distance between the first massage head 1111 and the second massage head 1121 to have an appropriate pinching force.

[0077] Exemplarily, the angle a1 of rotation of the first massage member 111 around the first axis 14 can be 1°, 10°, 15°, 20°, 30°, 45°, 50°, 60°, 70°, 80° or any angle greater than 0° and less than or equal to 80°, and can be specifically set according to the actual situation.

[0078] In this way, the first massage member 111 can reciprocally rotate around the first axis 14 at an appropriate angle, which helps to reduce the situation where the angle a1 of rotation of the first massage member 111 around the first axis 14 is too large, and thus helps to reduce the situation where the distance between the first massage head 1111 and the second massage head 1121 is too small, resulting in too large a pinching force.

[0079] In some embodiments, when the airbag 12 changes from the non-inflated state to the inflated state, the transmission member 13 rotates around the second axis 15 by an angle a2 under the drive of the first massage member 111, where 0 < a2 ≤ 360°, and the transmission member 13 drives the second massage member 112 to swing at least from the position where the second massage head 1121 is farthest from the first massage head 1111 to the position where the second massage head 1121 is closest to the first massage head 1111.

[0080] In this way, the transmission member 13 can reciprocally rotate around the second shaft 15 within an angular range of less than or equal to 360° under the drive of the first massage member 111, such that the transmission member 13 can reciprocally rotate one full circle or an angle less than one full circle, thereby enabling the rotation of the transmission member 13 to be converted into a relatively large-amplitude yaw of the second massage member 112. The transmission member 13 drives the second massage member 112 to swing at least from the position where the second massage head 1121 is farthest from the first massage head 1111 to the position where the second massage head 1121 is closest to the first massage head 1111, enabling the second massage head 1121 to complete at least one kneading action, thereby contributing to ensuring the kneading massage of the neck and shoulder massager 100.

[0081] Exemplarily, the angle a2 by which the transmission member 13 rotates around the second shaft 15 under the drive of the first massage member 111 can be 50°, 90°, 120°, 160°, 200°, 250°, 300°, 360° or any angle greater than 0° and less than or equal to 360°, and can be specifically set according to actual circumstances.

[0082] Among them, the transmission member 13 can achieve non-continuous multi-turn rotation, such that after the airbag 12 is inflated, the transmission member 13 rotates a relatively small stroke, that is, it can relatively quickly achieve a relatively large-amplitude yaw of the second massage member 112 under the condition of a certain inflation speed, thereby realizing the kneading massage of the second massage member 112 and the first massage member 111 on the human body.

[0083] In some embodiments, when the airbag 12 changes from a non-inflated state to an inflated state, the angle by which the first massage member 111 rotates around the first shaft 14 is a1, and the angle by which the transmission member 13 rotates around the second shaft 15 under the drive of the first massage member 111 is a2, then a1 < a2.

[0084] In this way, a small-angle rotation of the first massage member 111 can achieve a large-angle rotation of the transmission member 13, thereby contributing to reducing the expansion stroke of the airbag 12.

[0085] Exemplarily, the angle a1 by which the first massage member 111 rotates around the first shaft 14 can be 1°, 10°, 15°, 20°, 30°, 45°, 50°, 60°, 70°, 80° or any angle greater than 0° and less than or equal to 80°, and the angle a2 by which the transmission member 13 rotates around the second shaft 15 under the drive of the first massage member 111 can be any angle greater than a1 and less than or equal to 360°, and can be specifically set according to actual circumstances.

[0086] In this way, the first massage member 111 and the transmission member 13 can rotate at appropriate angles respectively, which helps to ensure that a small-angle rotation of the first massage member 111 can achieve a large-angle rotation of the transmission member 13, thereby contributing to reducing the expansion stroke of the airbag 12.

[0087] In some embodiments, the first axis 14 is coincident with or parallel to the second axis 15. This helps to achieve a smooth transmission of the force between the first massage member 111 and the transmission member 13, helps to improve the stability of the rotation between the first massage member 111 and the transmission member 13, and also helps to reduce the rotation deviation of the first massage member 111.

[0088] Please also read Figures 4 to 7 In some embodiments, the shoulder and neck massager 100 may include a gear set 16, and the first massage member 111 drives the transmission member 13 to rotate through the gear set 16. The gear set 16 includes a first gear 161 and a second gear 162, the diameter of the second gear 162 is smaller than the diameter of the first gear 161, and the second gear 162 is directly or indirectly meshed with the first gear 161, the first gear 161 is connected to the first massage member 111, and the second gear 162 is connected to the transmission member 13.

[0089] In this way, the gear set 16 helps to cooperate with the transmission member 13 to realize the transmission of the driving force from the first massage member 111 to the second massage member 112, thereby helping to improve the transmission efficiency of the first massage member 111 and the second massage member 112. The gear set 16 also helps to meet the setting requirements of the relative position change of the first shaft 14 and the second shaft 15 in space, and also helps to provide the required transmission ratio to meet the design requirements of the rotation angle between the first massage member 111 and the transmission member 13.

[0090] In some embodiments, the transmission ratio of the gear set 16 is i, i> 1. Thus, by making the transmission ratio greater than, when the first massage member 111 rotates at a smaller angle, the transmission member 13 can achieve a larger angle of rotation driven by the gear set 16, which helps to reduce the expansion stroke of the airbag 12.

[0091] In some embodiments, the first gear 161 rotates around the first shaft 14 , and the second gear 162 rotates around the second shaft 15 . The teeth of the first gear 161 are arranged around the second shaft 15 and mesh with the second gear 162 on the side of the second shaft 15 away from the first shaft 14 .

[0092] In this way, when the first massage member 111 rotates around the first axis 14, the first massage member 111 can use the first axis 14 as a fulcrum and more powerfully drive the transmission member 13 to rotate around the second axis 15 through the second gear 162, which helps to increase the massage force of the second massage member 112, thereby helping to improve the massage effect of the second massage member 112 on the massage area.

[0093] In some embodiments, the first massage member 111 is provided with an avoidance through-hole 1113, and the second shaft 15 passes through the avoidance through-hole 1113. In this way, the first massage member 111 can avoid the second shaft 15 through the avoidance through-hole 1113, which helps to reduce the interference of the second shaft 15 on the rotation path of the first massage member 111, thereby helping to ensure the normal rotation of the first massage member 111, and also helping to improve the compactness of the structures of the first massage member 111 and the second shaft 15, and helping to save the space of the neck and shoulder massager 100 occupied by the first massage member 111 and the second shaft 15.

[0094] In addition, the avoidance through-hole 1113 helps to reduce the weight of the first massage member 111, thereby helping to reduce the weight of the neck and shoulder massager 100, so that the neck and shoulder massager 100 can be made lightweight while ensuring the massage work.

[0095] In some embodiments, the groove wall 1112 of the avoidance through-hole 1113 is provided with saw teeth to form a first gear 161, and the second gear 162 is at least partially located in the avoidance through-hole 1113 to mesh with the first gear 161.

[0096] In this way, by making the first gear 161 and the second gear 162 cooperate within the avoidance through-hole 1113, it helps to make full use of the space within the avoidance through-hole 1113, and also helps to reduce the occupation of the assembly space in the extending direction of the second shaft 15 when the first gear 161 and the second gear 162 cooperate outside the avoidance through-hole 1113, making the overall structure more compact, and helping to save the space of the neck and shoulder massager 100 occupied by the first gear 161 and the second gear 162.

[0097] In some embodiments, an installation groove 131 is formed on the outer wall surface 132 of the transmission member 13 extending along the direction surrounding the second shaft 15. The extending direction of the installation groove 131 defines an extending plane 1311, and the extending plane 1311 is inclined relative to the first shaft 14; the second massage member 112 is sleeved on the transmission member 13 within the installation groove 131, and the part of the second massage member 112 received within the installation groove 131 matches the installation groove 131 and can rotate relative to the transmission member 13 along the extending direction of the installation groove 131 as the transmission member 13 rotates around the second shaft 15.

[0098] In this way, it helps to ensure that the transmission member 13 can drive the second massage member 112 to achieve yaw, thereby helping to ensure the kneading massage of the second massage member 112 on the human body, and also helping to improve the compactness of the structures of the second massage member 112 and the transmission member 13, and helping to save the space of the neck and shoulder massager 100 occupied by the second massage member 112 and the transmission member 13.

[0099] Please refer to Figure 7 and Figure 8, in some embodiments, the minimum distance between the first shaft 14 and the second shaft 15 is D, the diameter of the second gear 162 is d, and D≥d.

[0100] In this way, it helps to ensure an appropriate distance between the first shaft 14 and the second shaft 15, helps to ensure that the second gear 162 has enough space to rotate, and thus helps to ensure the normal rotation of the second gear 162. It also helps the gear set 16 to select a second gear 162 with a moderately increased diameter, so that more teeth can be provided on the outer circumference of the second gear 162 to adjust the rotation speed of the transmission member 13.

[0101] Please refer to Figure 3 and Figure 9 , in some embodiments, the neck and shoulder massager 100 may include a base 18. The first massage member 111 is rotatably mounted on the base 18 around the first shaft 14, and the second massage member 112 is slidably connected to the base 18 along the extending direction of the second shaft 15.

[0102] In this way, the neck and shoulder massager 100 can connect multiple components through the base 18, making the connection of multiple components of the neck and shoulder massager 100 relatively compact, and thus helping to improve the structural compactness of the neck and shoulder massager 100.

[0103] In some embodiments, the airbag 12 may have a working surface 121 acting on the first massage member 111. The neck and shoulder massager 100 may further include a reset member 17, and the reset member 17 acts on the first massage member 111 and the base 18 to make the first massage member 111 abut against the working surface 121.

[0104] In this way, during the inflation process of the airbag 12, the reset member 17 can apply a force to the first massage member 111 so that the first massage member 111 can abut against the working surface 121 of the airbag 12, which helps to reduce the situation that the first massage member 111 deviates from the working surface 121 of the airbag 12 during rotation, and thus helps to ensure that the airbag 12 can effectively apply a force to the first massage member 111. During the deflation process of the airbag 12, the reset member 17 can also act on the first massage member 111 to make the first massage member 111 rotate in the reverse direction to keep close to the working surface 121 of the airbag 12, so that the first massage member 111 and the second massage member 112 can move with the deflation and inflation of the airbag through the reset member 17, and also makes the reset member 17 cooperate closely with the airbag 12, which helps to achieve the smooth reset of the first massage member 111.

[0105] In some embodiments, the reset member 17 is a torsion spring wound around the first shaft 14. In this way, the torsion spring can generate an elastic force through torsional deformation to apply a force to the first massage member 111, which helps to ensure the normal operation of the first massage member 111.

[0106] In addition, since the torsion spring has the characteristics of uniform force and stable quality, it helps to better achieve the smooth reset of the first massage member 111.

[0107] In some embodiments, the neck and shoulder massager 100 has a working state and a non-working state opposite to the working state. In the non-working state, the airbag 12 is in a non-inflated state.

[0108] In this way, before starting the neck and shoulder massager 100, the non-inflated state of the airbag 12 helps to protect the airbag 12, helps to reduce the situation where the airbag 12 is compressed when the neck and shoulder massager 100 is in the non-working state and the airbag 12 is in the inflated state, and thus helps to reduce the damage of the airbag 12.

[0109] In some embodiments, in the non-working state, a wearing gap suitable for the massage part to enter is formed between the first massage head 1111 and the second massage head 1121.

[0110] In this way, before starting the neck and shoulder massager 100, the wearing gap can be suitable for the human massage part to enter, which helps to facilitate the user's wearing and thus helps to improve the wearing efficiency of the neck and shoulder massager 100.

[0111] In summary, for the neck and shoulder massager 100 provided by the embodiment of the present utility model, the airbag 12 of the neck and shoulder massager 100 drives the first massage member 111 and the second massage member 112 to move simultaneously by inflating and expanding. The first massage member 111 and the second massage member 112 are adapted to move with the deflation and contraction of the airbag 12, so that when the airbag 12 inflates and expands or deflates and contracts, the first massage head 1111 and the second massage head 1121 approach or move away from each other to achieve kneading massage. In this way, the airbag 12 can output a driving force by inflating and expanding to enable both the first massage member 111 and the second massage member 112 to move. The first massage member 111 and the second massage member 112 are adapted to move with the deflation and contraction of the airbag 12, so that when the airbag 12 inflates and expands or deflates and contracts, both the first massage member 111 and the second massage member 112 can move, enabling the first massage head 1111 and the second massage head 1121 to act on the massage part respectively to achieve kneading massage. The first massage head 1111 and the second massage head 1121 can also cooperate with each other to clamp the massage part when approaching each other to achieve manual clamping massage, which helps to improve the user experience. Since the airbag 12 has a certain elasticity, the first massage head 1111 and the second massage head 1121 can adaptively rebound during the clamping massage, which helps to achieve soft massage rather than hard massage.

[0112] The time period for the first massage head 1111 and the second massage head 1121 to approach and then move away from each other to complete a reciprocating motion is one massage cycle. The maximum inflation volume of the airbag 12 when inflated is different in at least two massage cycles, so that the minimum distance between the first massage head 1111 and the second massage head 1121 when approaching each other is different in at least two massage cycles. In this way, by adjusting the maximum inflation volume of the airbag 12, the movement amplitude of the first massage member 111 and the second massage member 112 can be adjusted, which helps to adjust the minimum distance between the first massage head 1111 and the second massage head 1121 to adjust the pinching force, helps to enrich the massage techniques of the neck and shoulder massager 100, helps to improve the applicability of the neck and shoulder massager 100 to suit people who need different pinching forces, and also helps to improve the user experience.
