Description

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. Conventional neck and shoulder massagers mostly drive the first massage member and the second massage member to move through a driving mechanism composed of components or parts such as motors and speed reducers to imitate the kneading massage of human hands. Not only is the weight of the driving mechanism relatively large, making the entire neck and shoulder massager appear rather bulky and affecting the user experience, but also the rigid mechanical force output by the driving mechanism has a rather strong massage effect when acting on the human body via the first massage member and the second massage member, and thus cannot achieve a soft and comfortable massage experience. Content of the Utility Model

[0003] An embodiment of the utility model provides a neck and shoulder massager to improve at least one of the above technical problems.

[0004] The embodiment of the utility model realizes the above object through the following technical solutions.

[0005] The embodiment of the utility model provides a neck and shoulder massager, which includes a massage assembly and an airbag. The massage assembly includes a first massage member having a first massage head and a second massage member having a second massage head. The airbag directly drives the first massage member to move by inflating and expanding. The first massage member is adapted to move as the airbag deflates and contracts, and the first massage member is connected to the second massage member to drive the second massage member to move, so that the first massage head and the second massage head approach or move away from each other to achieve kneading massage.

[0006] In some embodiments, the neck and shoulder massager includes a transmission member connected between the first massage member and the second massage member. When the first massage member moves, the first massage member drives the second massage member to move via the transmission member.

[0007] In some embodiments, the first massage member is adapted to reciprocally rotate about a first axis. 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.

[0008] 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 amount 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°.

[0009] 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 transmission member rotates around the second axis driven by the first massage member at an angle a2, 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.

[0010] 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 a maximum. When the airbag changes from the non-inflated state to the inflated state, the angle at which the first massage part rotates around the first axis is a1, and the angle at which the transmission part rotates around the second axis driven by the first massage part is a2, then a1<a2.

[0011] In some embodiments, the first axis is coincident or parallel to the second axis.

[0012] In some embodiments, the shoulder and neck 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 the diameter of the first gear, and the second gear is directly or indirectly meshed with the first gear, the first gear is connected to the first massage member, and the second gear is connected to the transmission member.

[0013] In some embodiments, the gear ratio of the gear set is i, i>1.

[0014] 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.

[0015] In some embodiments, a minimum distance between the first shaft and the second shaft is D, a diameter of the second gear is d, and D≥d.

[0016] In some embodiments, the first massage member is provided with an avoidance opening, and the second shaft is passed through the avoidance opening.

[0017] 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 located in the avoidance passage to mesh with the first gear.

[0018] In some embodiments, the airbag has an action surface that acts on the first massage piece; the shoulder and neck massager includes a reset piece and a base, the first massage piece is connected to the base by rotating around a first axis, and the reset piece acts on the first massage piece and the base to make the first massage piece press against the action surface.

[0019] In some embodiments, the reset element is a torsion spring wound around the first shaft.

[0020] In some embodiments, an installation groove is formed on the outer wall surface of the transmission member and extends along the direction around the second axis. The extending direction of the installation groove defines an extending plane, and the extending plane is inclined relative to the first axis; the second massage member is sleeved on the transmission member in the installation groove, and the part of the second massage member received in the installation groove matches the installation groove and can rotate relative to the transmission member along the extending direction of the installation groove as the transmission member rotates around the second axis.

[0021] In some embodiments, the neck and shoulder massager includes a base. The first massage member is rotatably mounted on the base around the first axis, and the second massage member is slidably connected to the base along the extending direction of the second axis.

[0022] In some embodiments, the neck and shoulder massager has a working state and a non-working state opposite to the working state. The airbag 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. In the non-working state, the airbag is in the non-inflated state.

[0023] 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 and the second massage head.

[0024] In some embodiments, the neck and shoulder massager includes an air pump. The air pump is connected to the airbag and is configured to have at least two different maximum inflation amounts of filling gas into the airbag, so that the minimum distances when the first massage head and the second massage head approach each other at least twice are different.

[0025] In some embodiments, the neck and shoulder massager includes a controller connected to the air pump. The controller is configured to receive a user instruction to control the air pump to fill the airbag with a set amount of gas.

[0026] The neck and shoulder massager provided by the embodiment of the present utility model includes a massage component and an airbag. The massage component includes a first massage member with a first massage head and a second massage member with a second massage head. The airbag directly drives the first massage member to move by inflating and expanding. The first massage member is adapted to move as the airbag deflates and contracts. The first massage member is connected to the second massage member to drive the second massage member to move, so that the first massage head and the second massage head approach or move away from each other to achieve kneading massage. In this way, the airbag can output a driving force by inflating and expanding to enable the first massage member to drive the second massage member to move. The movement of the first massage member as the airbag deflates and contracts can drive the second massage member to move. Thus, when the airbag inflates and expands or deflates and contracts, both the first massage member and the second massage member can move, enabling the first massage head and the second massage head to act on the massage part respectively 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 imitation of human hand pinching massage, which helps to improve the user experience. Since the airbag has a certain elasticity, the first massage head and the second massage head can adaptively rebound during pinching massage, which helps to achieve soft massage rather than hard massage. In addition, the airbag is light in weight, which helps to reduce the overall weight of the neck and shoulder massager, making the neck and shoulder massager more portable and providing a better user experience for the user.

[0043] Please refer to Figure 1 , an embodiment of the present utility model provides a neck and shoulder massager 100. The neck and shoulder massager 100 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.

[0044] In some embodiments, the airbag 12 directly drives the first massage member 111 to move by inflating and expanding. The first massage member 111 is adapted to move with the deflation and contraction of the airbag 12, and the first massage member 111 is connected to the second massage member 112 to drive the second massage member 112 to move, so that the first massage head 1111 and the second massage head 1121 approach or move away from each other to achieve kneading massage.

[0045] In this way, the airbag 12 can output a driving force by inflating and expanding, so that the first massage member 111 drives the second massage member 112 to move. The movement of the first massage member 111 as the airbag 12 deflates and contracts can drive the second massage member 112 to move. 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 area 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 area when approaching each other to achieve manual-like pinching massage, which helps to improve the massage effect of the first massage head 1111 and the second massage head 1121 on the massage area. Since the airbag 12 has a certain elasticity, the first massage head 1111 and the second massage head 1121 can rebound adaptively during pinching massage, which helps to achieve soft massage rather than strong massage, thus helping to improve the user experience. 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.

[0046] Among them, the first massage member 111 is adapted to move as the airbag 12 deflates and contracts, which can 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.

[0047] Exemplarily, the airbag 12 directly drives the first massage member 111 to move by inflating and expanding. The movement of the first massage member 111 drives the second massage member 112 to move, so that the first massage head 1111 and the second massage head 1121 approach each other to achieve pressing on the massage area. The first massage member 111 can move with the deflation and contraction of the airbag 12 through a transfer structure. The movement of the first massage member 111 drives the second massage member 112 to move, so that the first massage head 1111 and the second massage head 1121 move away from each other to release the massage area. Thus, 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 first massage member 111 is connected to the second massage member 112 to drive the second massage member 112 to move, which may mean that the first massage member 111 is connected to the second massage member 112 through a transmission structure, and when the first massage member 111 moves, it drives the second massage member 112 to move through the transmission structure. 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 respectively through inflation and expansion to drive the first massage member 111 and the second massage member 112 to move, which can be specifically set according to actual situations. Hereinafter, taking the first massage member 111 being connected to the second massage member 112 through a transmission structure and the first massage member 111 driving the second massage member 112 to move through the transmission structure when the first massage member 111 moves as an example for illustration.

[0049] In some embodiments, the neck and shoulder massager 100 may include a transmission member 13, and the transmission member 13 is connected between the first massage member 111 and the second massage member 112. When the first massage member 111 moves, the first massage member 111 drives the second massage member 112 to move via the transmission member 13.

[0050] In this way, the first massage member 111 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 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, also 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 and is convenient for manufacturing.

[0051] Among them, the transmission member 13 can be an eccentric wheel. Then, when the first massage member 111 moves, the first massage member 111 can drive the second massage member 112 to perform a yawing movement 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 of the first massage member 111 and the second massage member 112 to realize the imitation of human hand pinching massage between the first massage member 111 and the second massage member 112.

[0052] Please refer to Figure 2 and Figure 3 , in some embodiments, the first massage member 111 can reciprocally rotate around the first axis 14, the transmission member 13 reciprocally rotates around the second axis 15 in the same direction as 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.

[0053] In this way, 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, so as to achieve the reciprocating manual-like pinching massage of the first massage member 111 and the second massage member 112.

[0054] Exemplarily, the first massage member 111 can reciprocally rotate around the first axis 14 when the airbag 12 inflates and expands and deflates and contracts, so as to achieve the reciprocating movement of the first massage member 111, and further achieve the reciprocating movement of the first massage member 111 and the second massage member 112, which helps to ensure the normal operation of the neck and shoulder massager 100.

[0055] 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. Then, the inflation amount inside the airbag 12 can be controlled so that the airbag 12 can be in different states. For example, by increasing the inflation amount inside the airbag 12, the airbag 12 can gradually change from the non-inflated state to the inflated state. Also, for example, by reducing the inflation amount inside the airbag 12, the airbag 12 can gradually change from the inflated state to the non-inflated state, which can be specifically set according to the actual situation.

[0056] In some embodiments, when the airbag 12 changes from the non-inflated state to the inflated state, the angle by which the first massage member 111 rotates 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, and thus helps to ensure that the first massage head 1111 and the second massage head 1121 have an appropriate distance to have an appropriate pinching force.

[0057] Exemplarily, the angle a1 by which the first massage member 111 rotates 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°, which can be specifically set according to the actual situation.

[0058] 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 by which the first massage member 111 rotates 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.

[0059] 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 shaft 15 by an angle a2 under the drive of the first massage member 111, where 0 < a2 ≤ 360°. 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.

[0060] In this way, the transmission member 13 can reciprocally rotate around the second shaft 15 within an angle range less than or equal to 360° under the drive of the first massage member 111, so 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 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, thus contributing to ensuring the kneading massage of the neck and shoulder massager 100.

[0061] 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 the actual situation.

[0062] Among them, the transmission member 13 can achieve non-continuous multi-turn rotation, so that after the airbag 12 is inflated, the transmission member 13 rotates a smaller stroke, that is, it can achieve a large-amplitude yaw of the second massage member 112 relatively quickly when the inflation speed is constant, thereby realizing the kneading massage of the second massage member 112 and the first massage member 111 on the human body.

[0063] In some embodiments, when the airbag 12 changes from the non-inflated state to the 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.

[0064] 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.

[0065] Exemplarily, the angle a1 at which the first massage member 111 rotates about the first axis 14 may be 1°, 10°, 15°, 20°, 30°, 45°, 50°, 60°, 70°, 80°, or any angle greater than 0° and less than or equal to 80°. The angle a2 at which the transmission member 13 rotates about the second axis 15 driven by the first massage member 111 may be any angle greater than a1 and less than or equal to 360°, and can be specifically set according to the actual situation.

[0066] 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 realizes a large-angle rotation of the transmission member 13, thereby helping to reduce the expansion stroke of the airbag 12.

[0067] In some embodiments, the first axis 14 coincides with or is parallel to the second axis 15. In this way, it helps to achieve the smooth transmission of the acting force between the first massage member 111 and the transmission member 13, helps to improve the smoothness of the rotation between the first massage member 111 and the transmission member 13, and also helps to reduce the situation of rotational deviation of the first massage member 111.

[0068] Please refer to Figures 4 to 7 , in some embodiments, the neck and shoulder 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 may include a first gear 161 and a second gear 162. The diameter of the second gear 162 is smaller than that of the first gear 161 and is directly or indirectly engaged 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.

[0069] In this way, the gear set 16 helps to cooperate with the transmission member 13 to achieve 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 between the first massage member 111 and the second massage member 112. The gear set 16 also helps to meet the setting requirements for the relative position change of the first axis 14 and the second axis 15 in space, and also helps to provide the required transmission ratio to meet the design requirements for the rotation angles between the first massage member 111 and the transmission member 13.

[0070] In some embodiments, the transmission ratio of the gear set 16 is i, and i > 1. In this way, by making the transmission ratio greater than 1, when the first massage member 111 rotates at a small angle, the transmission member 13 can achieve a large-angle rotation driven by the gear set 16, which helps to reduce the expansion stroke of the airbag 12.

[0071] In some embodiments, the first gear 161 rotates about the first shaft 14 as the rotation center axis, the second gear 162 rotates about the second shaft 15 as the rotation center axis, 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.

[0072] In this way, when the first massage member 111 rotates about the first shaft 14, the first massage member 111 can use the first shaft 14 as a fulcrum and drive the transmission member 13 to rotate about the second shaft 15 more powerfully through the second gear 162, which helps to increase the massage force of the second massage member 112, and thus helps to improve the massage effect of the second massage member 112 on the massage area.

[0073] 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.

[0074] 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 can have 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 an appropriately increased diameter, so that more teeth can be arranged on the outer periphery of the second gear 162 to adjust the rotation speed of the transmission member 13.

[0075] In some embodiments, the first massage member 111 may be 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, thus helping to ensure the normal rotation of the first massage member 111, and also helps to improve the compactness of the structures of the first massage member 111 and the second shaft 15, and helps to save the space of the neck and shoulder massager 100 occupied by the first massage member 111 and the second shaft 15.

[0076] In addition, the avoidance through-hole 1113 helps to reduce the weight of the first massage member 111, and thus helps to reduce the weight of the neck and shoulder massager 100, so that the neck and shoulder massager 100 can be made lighter while ensuring the massage work.

[0077] In some embodiments, the groove wall 1112 of the avoidance through-hole 1113 is provided with teeth to form the first gear 161, and at least a part of the second gear 162 is located in the avoidance through-hole 1113 to mesh with the first gear 161.

[0078] In this way, by mating the first gear 161 with the second gear 162 within the avoidance through-port 1113, it helps to make full use of the space within the avoidance through-port 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 are mated outside the avoidance through-port 1113, making the overall structure more compact and helping to save the space of the first gear 161 and the second gear 162 in the neck and shoulder massager 100.

[0079] Please also refer to Figure 1 and Figure 8 , in some embodiments, the airbag 12 has a working surface 121 acting on the first massage member 111. The neck and shoulder massager 100 may include a reset member 17 and a base 18. The first massage member 111 is rotatably connected to the base 18 around the first shaft 14, 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.

[0080] In this way, during the process of the airbag 12 inflating and expanding, 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, thereby helping to ensure that the airbag 12 can effectively apply a force to the first massage member 111. During the process of the airbag 12 deflating and contracting, the reset member 17 can also act on the first massage member 111, causing the first massage member 111 to rotate in the reverse direction to keep closely attached to the working surface 121 of the airbag 12, so that the first massage member 111 can move with the deflation and contraction of the airbag 12 and drive the second massage member 112 to move, and also makes the reset member 17 and the airbag 12 cooperate closely, which helps to achieve the smooth reset of the first massage member 111.

[0081] In some embodiments, the reset member 17 is a torsion spring 171 wound around the first shaft 14. In this way, the torsion spring 171 can generate an elastic force through torsional deformation to apply a force to the first massage member 111, thereby helping to ensure the normal operation of the first massage member 111.

[0082] In addition, since the torsion spring 171 has the characteristics of uniform force and stable quality, it helps to better achieve the smooth reset of the first massage member 111.

[0083] In some embodiments, an installation groove 131 is formed in the outer wall surface 132 of the transmission member 13 and extends along the direction around 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 in the installation groove 131, and the part of the second massage member 112 received in 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.

[0084] 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. It also helps to improve the compactness of the structure of the second massage member 112 and the transmission member 13, and helps to save the space of the neck and shoulder massager 100 occupied by the second massage member 112 and the transmission member 13.

[0085] In some embodiments, 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.

[0086] 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, thereby helping to improve the compactness of the structure of the neck and shoulder massager 100.

[0087] 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.

[0088] 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 in the non-working state, and thus helps to reduce the damage of the airbag 12.

[0089] 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.

[0090] 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.

[0091] Please refer to Figure 8 and Figure 9, in some embodiments, the neck and shoulder massager 100 may include an air pump 19. The air pump 19 is connected to the airbag 12 and is configured to have at least two different maximum inflation amounts for 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.

[0092] In this way, the maximum inflation amount 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 need different kneading strengths, thereby helping to improve the user experience.

[0093] In some embodiments, the neck and shoulder massager 100 may include a controller 20 connected to the air pump 19. The controller 20 is configured to receive user instructions to control the air pump 19 to inflate the airbag 12 with a set amount of gas.

[0094] In this way, it helps to improve the adjustability of the massage of the neck and shoulder massager 100. The user can control the amount of gas inflated into the airbag 12 by the air pump 19 according to their own needs through 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 requirements.

[0095] 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 inflate more 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 inflate less 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.

[0096] In summary, for the neck and shoulder massager 100 provided by the embodiment of the present utility model, the massage assembly 11 of the neck and shoulder massager 100 includes a first massage member 111 having a first massage head 1111 and a second massage member 112 having a second massage head 1121. The airbag 12 directly drives the movement of the first massage member 111 by inflating and expanding. The first massage member 111 is adapted to move as the airbag 12 deflates and contracts. The first massage member 111 is connected to the second massage member 112 to drive the second massage member 112 to move, so that 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 the first massage member 111 to drive the second massage member 112 to move. The movement of the first massage member 111 as the airbag 12 deflates and contracts can drive the second massage member 112 to move. Thus, when the airbag 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 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. 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.
