Description

Technical Field

[0001] This utility model relates to personal care equipment, and more particularly to a massage device. Background Technology

[0002] Most massage chairs on the market today typically offer basic massage functions for areas such as the head, neck, waist, back, and calves. More high-end chairs may also include separate massage mechanisms for the arms and thighs, allowing for more targeted massage of these areas. However, these arm and thigh massage mechanisms usually operate independently, leading to a more complex structure and increased size. This often results in the use of airbags, which, while more compact, limits the massage effect.

[0003] For example, a massage chair disclosed in Chinese invention patent (CN100396268C) has a massage device on the armrests. This massage device uses airbags to knead and massage the user's arms.

[0004] The massage chair structure shown in the aforementioned patent uses an airbag-type massage mechanism, which can only perform grasping and kneading massage, and cannot perform massage movements similar to kneading, thus resulting in a poor massage effect. Furthermore, the massage device shown in this patent can only massage the arms and cannot simultaneously massage the user's buttocks.

[0005] For example, some existing massage devices are not stable enough and may deform after prolonged use. Furthermore, after extended use, the massage mechanisms on both sides may become out of sync, affecting the massage experience. Utility Model Content

[0052] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0053] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0054] Example 1

[0055] This embodiment provides a massage device, specifically a massage chair. A massage component 1 is installed on each of the two armrests of the massage chair, and each massage component 1 is used to massage one of the user's arms and one side of the buttocks. Thus, the two massage components 1 can simultaneously massage both of the user's arms and both sides of the buttocks. The structure of the remaining parts of the massage chair is widely existing in the prior art and is not the focus of this embodiment; therefore, it will not be elaborated upon further.

[0056] Figure 1 and Figure 2 The massage process of the massage component 1 described above is depicted from a top-down perspective. Figure 3 and Figure 4 The massage process of the massage component 1 described above is depicted from a frontal view. It can be seen that the massage component 1 includes a hand massage section 11 located on the armrest of the massage chair, and a buttock massage section 12 located on the inner side of the armrest, as shown... Figure 5 As shown. The hand massage unit 11 uses a kneading motion to massage the arm area, therefore the hand massage unit 11 has a first kneading massage area 13 for the user to place their arm, as shown. Figure 6 As shown. By periodically or non-periodically changing the width of the first kneading massage area 13, a kneading massage effect can be achieved on the user's arms. The buttock massage parts 12 of the two massage components 1 are respectively located on one side of the two armrests facing each other. The massage elements of the two buttock massage parts 12 (described later) are arranged facing each other, and a second kneading massage area 14 for placing the user's buttocks and thighs is formed between the left and right buttock massage parts 12. By periodically or non-periodically changing the width of this second kneading massage area 14, a kneading massage effect can be achieved on the user's buttocks.

[0057] Since the two massage components 1 on the massage chair have the same structure, the following description will focus on the structure of either one of the massage components 1. It should be noted that the massage component 1 in this embodiment is used to massage the hands and buttocks. However, as a simple alternative to this embodiment, if the massage component 1 is placed on a massage device other than the massage chair, it can be used for other types of massage devices. For example, the two massage components 1 can be placed on a separate buttocks and arm massage device, allowing the user to massage their arms and buttocks by mounting it on any place with a seat. Furthermore, the massage component 1 can be used to massage other parts of the body, such as a leg massage device, where the massage component simultaneously massages the thighs and calves, or the calves and soles of the feet, etc. Alternatively, it can be a shoulder and neck massage device, where the massage component simultaneously massages the shoulders and neck. Therefore, the structure of the massage component 1 is not limited to the hand massage component 11 and the buttocks massage component 12. Therefore, in the following description of the structure of the massage component 1, the first massage component 15 and the second massage component 16 will be used instead of the hand massage component 11 and the buttocks massage component 12 mentioned above.

[0058] refer to Figure 7 , Figure 8 , Figure 17 and Figure 18The massage component 1 in this embodiment includes: a first massage part 15, a second massage part 16, a rotating shaft 17, and a drive part 18; the rotating shaft 17 is arranged along the width direction of the first massage part 15. If the side of the first massage part 15 that acts on the user's body is considered the front, and the side away from the user's body is considered the back, then the width direction is from the front to the back (e.g., Figure 17 and 18 (The direction indicated by the arrow in the image). The pivot 17 is located on the side of the massage chair along the width of the armrest.

[0059] In this embodiment, as Figure 3 and Figure 8 As shown, the width of the first massage unit 15 is aligned with the left-right direction of the massage chair. The first massage unit 15 is positioned on the side of the massage chair, spanning the armrest of the massage chair via a pivot 17. The drive unit 18 is located on the side of the massage chair, in the area between the two massage arms 151 (described later) of the first massage unit 15. The space formed by the two massage arms 151 clamping each other above the drive unit 18 becomes a space that can accommodate a massage part of the human body, such as the forearm, i.e., the first kneading massage area 13 (described later). The middle part of the pivot 17 is connected to the drive unit 18 and is driven to rotate by the drive unit 18. One end of the pivot 17 passes through one side massage arm 151 of the first massage unit 15 and connects to the second massage unit 16, while the other end passes through the other side massage arm 151 of the first massage unit 15. The first massage unit 15 and the second massage unit 16 can act on different parts of the human body respectively. The drive unit 18 drives the rotating shaft 17 to rotate, causing the first massage unit 15 and the second massage unit 16, which are eccentrically connected to the rotating shaft 17, to reciprocate along with the rotating shaft 17. Thus, by using one drive unit 18 and one rotating shaft 17 to simultaneously drive two massage units to reciprocate, two massage units can simultaneously massage different areas, allowing for an increase in the number of massage areas without increasing the number of drive units, thereby reducing costs. Furthermore, since the rotating shaft 17 is positioned along the width direction of the first massage unit 15, which coincides with the width direction of the massage chair and also with the left-right direction of the person sitting on the massage chair, the first massage unit 15 and the second massage unit 16, sequentially positioned on the rotating shaft 17, are also positioned along the left-right direction of the human body. When the first massage part 15 and the second massage part 16 act on the arms and thighs of a person sitting on a massage chair, for example, the arrangement direction and sequence of the first massage part 15 and the second massage part 16 are consistent with the arrangement direction and sequence of their corresponding massage parts. This not only conforms to ergonomics, but also greatly reduces the length of the rotating shaft 17, making the structure of the massage assembly 1 more compact and occupying less space. Moreover, the shorter rotating shaft 17 is not easily deformed. Even if it is subjected to radial force from both the first massage part 15 and the second massage part 16 at the same time during the massage, the rotating shaft 17 is not easily bent, and the performance of the massage assembly 1 is more stable.

[0060] Further reference Figure 9 and Figure 10 As described above, the first massage unit 15 in this embodiment includes two symmetrically arranged massage arms 151, which are symmetrically arranged with respect to the drive unit 18 disposed therebetween. The axis of symmetry may coincide with the drive axis of the drive unit 18, or it may be preset as an imaginary axis suitable for constructing the massage area between the two massage arms 151. The two massage arms 151 may also not be strictly symmetrically arranged, but may be arranged relative to each other in a manner that constitutes the massage area between them.

[0061] The drive unit 18 drives the rotating shaft 17 to rotate, thereby causing the two opposing massage arms 151 to reciprocate in a direction that moves closer to or further away from each other; in one embodiment, they can reciprocate in a direction that moves closer to or further away from the axis of symmetry. During the reciprocating swing, the two massage arms 151 of the first massage unit 15 move closer to or further away from each other in the width direction. When the two massage arms 151 move closer to each other, they can squeeze the massage area located between them. When the two massage arms 151 move further away from each other, they can release the squeeze on the massage area located between them, and the massage area, such as an arm, can be easily withdrawn from between the two massage arms. That is, during the massage process, the two massage arms have a maximum position and a minimum position, the minimum position being the minimum position of the first kneading massage area 13 described later between the two massage arms 151, such as... Figure 11 , Figure 13 The largest position is the largest position of the first kneading massage area 13, which will be described later, between the two massage arms 151. Figure 12 , Figure 14 Additionally, the second massage unit 16 includes a massage arm 161, and the drive unit 18 drives the massage arm 161 of the second massage unit 16 to reciprocate along the length direction of the shaft 17 via the rotating shaft 17. Similarly, the massage arms 161 of the two second massage units 16 also have a maximum position and a minimum position during the reciprocating swing. The maximum position is the maximum position of the second kneading massage area 14 (described later) between the two massage arms 161. Figure 12 The smallest position is the smallest position of the second kneading massage area 14, which will be described later, between the two massage arms 161. Figure 11 .

[0062] refer to Figure 9 and Figure 10The massage arms 151 and 161 of the first massage part 15 and the second massage part 16 respectively include massage elements 1511 and 1611 and fitting parts 1512 and 1612; the first kneading massage area 13 is formed between the massage elements 1511 and 1511 of the first massage part 15 which are arranged opposite each other on the left and right sides of the armrest of the massage chair; the massage elements 1611 of the second massage part 16 of the two massage components 1 are respectively located on the left and right sides of the massage chair, so that they are arranged opposite each other from the left and right sides of the massage chair, and the second kneading massage area 14 is formed between the massage elements 1611 on the left and right sides.

[0063] like Figure 17 and 18 The fitting portions 1512 and 1612 of the massage arms 151 and 161 are respectively obliquely fitted onto the rotating shaft 17 via sway wheels 19. The sway wheels 19 of the first massage part 15 and the second massage part 16 have different inclination angles. The radial slope angle between the sway wheels 19 of the first massage part 15 and the rotating shaft 17 is smaller than that between the sway wheels 19 of the second massage part 16 and the rotating shaft 17. In this embodiment, the radial slope angle between the sway wheels 19 of the first massage part 15 and the rotating shaft 17 is 5-7°, and the radial slope angle between the sway wheels 19 of the second massage part 16 and the rotating shaft 17 is 8-10°. As a result, the massage trajectory of the massage arm 151 of the first massage part 15 can be close to the extension curve of the arm, and the massage trajectory of the massage arm 161 of the second massage part 16 can be close to the physiological curve of the buttocks, while ensuring that the massage components 1511 and 1611 achieve kneading massage effects suitable for the arms and buttocks, respectively.

[0064] There is a height difference between the massage members 1511 and 1611 of the first massage unit 15 and the second massage unit 16. The massage member 1511 of the massage arm 151 of the first massage unit 15 is arranged on the upper side of the rotating shaft 17 along the height direction, and the massage member 1611 of the massage arm 161 of the second massage unit 16 is arranged on the lower side of the rotating shaft 17 along the height direction. Thus, when the first massage unit 15 and the second massage unit 16 massage the arm and buttock respectively, a height difference adapted to the arm and buttock can be formed between the first massage unit 15 and the second massage unit 16.

[0065] refer to Figure 9In this embodiment, the drive unit 18 is disposed between the two mating portions 1512 of the first massage unit 15. The width direction of the drive unit 18 is consistent with the width direction of the first massage unit 15, thereby ensuring a more compact placement space for the first massage unit 15. In this embodiment, the rotating shaft 17 extends along the width direction of the drive unit 18, with its two ends located on both sides of the drive unit 18. The rotating shaft 17 located on one side of the drive unit 18 is connected to one of the mating portions 1512 of the first massage unit 15, while the rotating shaft 17 on the other side is connected to the other mating portion 1512 of the first massage unit 15 and the mating portion 1612 of the second massage unit 16. Thus, the first massage unit 15 and the second massage unit 16 can be driven simultaneously by one drive unit 18 and one rotating shaft 17. The drive unit 18 in this embodiment includes a motor 181 and a reduction gearbox 182. The output shaft of the motor is perpendicular to the rotating shaft 17. The reduction gearbox 182 is used to convert the rotation of the motor output shaft into the rotation of the rotating shaft 17, thereby driving the first massage unit 15 and the second massage unit 16 to move periodically. The drive unit 18 also includes a fixing plate 183, on which the reduction gearbox 182 is fixed. The fixing plate 183 is fixed to the armrest of the massage chair.

[0066] like Figure 1 , Figure 9 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, massage components 1511 and 1611 are arranged along the left-right direction of the massage chair (the width direction of the first massage part). The left-right direction of the massage chair is the thickness direction of massage components 1511 and 1611. The front-back direction intersecting the left-right direction of the massage chair ( Figure 15 The top and bottom directions of the paper; Figure 17 The depth direction of the middle paper), which is the length direction of massage components 1511 and 1611. The vertical direction of the massage chair intersects the left and right directions of the massage chair ( Figure 1 The top and bottom directions of the paper; and Figure 15 The depth direction of the paper surface; Figure 17The width direction of massage components 1511 and 1611 is shown in the vertical direction of the paper. Massage arms 151 and 161 extend in both the vertical and horizontal directions of the massage chair, and are elongated strips longer in the horizontal direction than in the vertical direction. Along the length of the massage arms 151 and 161, a rotating shaft 17 is positioned at the middle of the massage arms 151 and 161 via fitting portions 1512 and 1612 and an eccentric wheel 19. The eccentric wheel 19 is an eccentric wheel with an inclined surface tilted relative to the axis of the rotating shaft 17. When the eccentric wheel 19 rotates eccentrically under the drive of the rotating shaft 17, the massage components 1511 and 1611 rotate eccentrically along with the eccentric wheel 19 via fitting portions 1512 and 1612. During the eccentric rotation of the two elongated massage components 1511 of the first massage section 15 along with their respective eccentric wheels 19, the spatial size of the first kneading massage area 13 between them is adjusted. During the oscillation process, the different parts of the massage element 1511 follow different trajectories. For simplicity, taking the outer edge of the massage element 1511 as an example, the running trajectory of the massage element 1511 during the process of adjusting the spatial size of the first kneading massage area 13 is explained. In the process of forming the minimum position of the first kneading massage area 13, after one end of the two massage elements 1511 approaches each other, from that end to the other end, the respective opposite parts of the two massage elements 1511 in their length direction (in this embodiment, the front-to-back direction of the massage chair) sequentially approach each other until the other ends of the two massage elements 1511 approach each other, so that both ends of the two massage elements 1511 are close to each other and the upper edges of the two massage elements 1511 are parallel, reaching the minimum position of the first kneading massage area 13 (e.g., ...). Figure 11 , Figure 13 During the formation of the maximum position of the first kneading massage area 13, after one end of the two massage pieces 1511 moves away from each other (e.g., starting from the minimum position of the first kneading massage area 13), from that one end to the other end, the respective opposite portions of the two massage pieces 1511 in their length direction move away from each other sequentially until the other ends of the two massage pieces 1511 move away from each other, so that both ends of the two massage pieces 1511 are away from each other and the upper edges of the two massage pieces 1511 are parallel to each other, reaching the maximum position of the first kneading massage area 13 (e.g., starting from the minimum position of the first kneading massage area 13). Figure 12 , Figure 14 The distance between the two massage pieces 1511 is greater at the maximum position of the first kneading massage area 13 than at the minimum position. The above example illustrates the formation process of the maximum and minimum positions, but is not limited to this. For example, the maximum and minimum positions are not limited to the two massage pieces being parallel to each other.

[0067] refer to Figure 13 and Figure 14This embodiment also includes a guide unit 20, comprising a guide plate 201 and a guide post 202. The guide plate 201 is fixed relative to the drive unit 18, for example, both are fixed to the support frame of the massage assembly 1 (not shown). A guide groove 2011 is provided on the guide plate 201 along the axial direction of the rotating shaft 17. The fitting parts 1512 and 1612 are provided with guide posts 202, which extend downward and are placed within the guide groove 2011. The depth of the guide groove 2011 is greater than the length of the guide post 202 entering the guide groove 2011, and the guide post 202 reciprocates along the guide groove 2011. Thus, when the massage members 1511 and 1611 rotate eccentrically with the eccentric wheel 19, the guide post 202 is restricted by the guide groove 2011 and can only reciprocate within the guide groove 2011. Through the interaction between the eccentric wheel 19 and the guide unit 20, the reciprocating oscillation of the massage member 1511 of the first massage unit 15 in the width direction is realized. The two massage members 1511 of the first massage unit 15 simultaneously reciprocate in the width direction, achieving a massage effect on the human body parts in the massage area. As described above, when the left and right massage arms 151, left and right swing wheels 19, left and right guide pillars 202, and left and right guide grooves 2011 of the first massage unit 15 are all arranged opposite each other, the two massage members 1511 can reciprocate in directions that simultaneously move closer to or further away from each other. The same applies to the two massage arms 161 respectively arranged on the left and right sides of the massage chair, and the description is omitted.

[0068] The first massage unit 15 has two guide posts 202 that limit the swing of the two massage members 1511 respectively, and the second massage unit 16 has one guide post 202 that limits the swing of the massage member 1611. Guide grooves 2011 are required to correspond to the three guide posts 202. The setting of the guide grooves 2011 will be explained below.

[0069] In this embodiment, as Figure 9 , Figure 13 and Figure 14 , Figure 17As shown, two guide grooves 2011 are provided. The rotating shaft 17 extends along the width direction of the first massage part 15 and the second massage part 16, that is, the two fitting parts 1512 of the first massage part 15 and the fitting part 1612 of the second massage part 16 are arranged sequentially along the axial direction of the rotating shaft 17. One fitting part 1512 of the first massage part 15 is close to the fitting part 1612 of the second massage part 16. The guide post 202 of both the fitting part 1512 and the fitting part 1612 protrude downwards from the fitting part. The guide groove 2011 is provided along the axial direction of the rotating shaft 17 on the guide plate 201 below the rotating shaft 17. One fitting part 1512 of the first massage part 15 and the fitting part 1612 of the second massage part 16, which is located close to it, share the guide groove 2011, and their guide posts 202 are placed in the same guide groove 2011. In this embodiment, the tilting directions of the tilting surfaces of the first massage unit 15's tilting wheel 19 and the second massage unit's tilting wheel 19 are in the same direction. During the eccentric rotation of the first massage unit 15 and the second massage unit 16 with the rotating shaft 17, the two guide posts 202 move in the same direction. This avoids interference between the two guide posts 202 during their reciprocating motion. The shared structure of the two guide posts 202 using the same guide groove 2011 makes the entire massage assembly 1 more compact. As a variation, the two fitting parts 1512 in the first massage unit 15 and the fitting part 1612 in the second massage unit 16 can also share the same guide groove 2011, that is, the three guide posts 202 are placed in the same guide groove 2011 extending axially along the rotating shaft 17. Furthermore, this embodiment uses a guide plate 201 as an example; in actual design, it is not limited to the plate shape, as long as there is space to set the guide groove 2011. As another variation, guide grooves 2011 corresponding to the guide posts 202 of the fitting portion 1612 can be provided above the fitting portion 1612, and guide grooves 2011 corresponding to the guide posts 202 of the fitting portion 1512 can be provided below the two fitting portions 1512 respectively, thereby providing three separate guide grooves 2011. Massage assembly

[0070] Furthermore, refer to Figure 17 and Figure 18In the vertical direction, the fitting portions of the massage arms 1511 and 1611 of the first massage unit 15 and the second massage unit 16 are both fitted onto the same rotating shaft 17. The massage arm 1511 of the first massage unit 15 extends obliquely upward from the rotating shaft 17, and the massage arm 1611 of the second massage unit 16 extends obliquely downward from the rotating shaft 17. The massage arm 1511 of the first massage unit 15 is positioned higher than the massage arm 1611 of the second massage unit 16. The guide plate 201 is located below the rotating shaft 17. The guide plate 201 is also located below each fitting portion 1512 and 1612. The guide post 202 on the first massage unit 15 is located on the side of the fitting portion 1512 away from the massage member 1511; the guide post 202 on the second massage unit 16 is located on the side of the fitting portion 1612 closer to the massage member 1611. Therefore, the guide posts 202 of the first massage unit 15 and the second massage unit 16 both extend downward from their respective fitting portions 1512 and 1612, and can be inserted into the guide grooves 2011 of the guide plate 201 as described above. As a simple alternative to this embodiment, the guide posts 202 on the first massage unit 15 can also be positioned on the side of the fitting portion 1512 closer to the massage member 1511; and the guide posts 202 on the second massage unit 16 can be positioned on the side of the fitting portion 1612 away from the massage member 1611, that is, the guide posts 202 on the first massage unit 15 and the second massage unit 16 extend in the same direction. Accordingly, the guide plate 201 can be placed above the fitting portion 1612. The guide posts 202 on the first massage unit 15 and the second massage unit 16 can also extend in different directions, and accordingly, the positions of their respective guide grooves 2011 need to be adjusted.

[0071] In addition, refer to Figure 15 and Figure 16 In this embodiment, the massage member 1511 of the first massage part 15 gradually increases in thickness from one end to the other along the length of the first kneading massage area 13. Specifically, it is thicker on the side closer to the user's palm and thinner on the side closer to the user's elbow. This allows the kneading massage area to adapt to the physiological curves of the user's arm with different thicknesses, enabling the massage parts of the first massage members 1511 and 1611 to wrap around the user's arm and increase the massage area. Furthermore, the pressing template surfaces on the opposing sides of the massage members 1511 and 1611 of the first massage part 15 are elastic, for example, made of soft rubber. Thus, within the aforementioned massage area, it can accommodate arms of different thicknesses and achieve a massage effect for arms of different thicknesses.

[0072] The massage chair of this application is equipped with a pair of massage components 1 (one massage component on each side is shown in the attached figure). During the massage, the two massage components 1 need to cooperate with each other to achieve coordinated massage movements. In this embodiment, the synchronous movement of the two massage components 1 is used as an example. If the movements of the two massage components 1 are not synchronized, for example, if the second massage part 16 for massaging the left buttock does not move in sync with the second massage part 16 for massaging the right buttock, then it is impossible for the second massage parts 16 on both sides to open and close simultaneously to massage the buttocks, nor is it possible for the second massage parts on both sides to move to the left or right simultaneously to massage.

[0073] Therefore, it is necessary to ensure that the two massage components 1 are always in the required coordinated state, such as in a synchronized state, during the massage process. This requires monitoring the movement state of the massage components 1 to determine whether the two massage components 1 are synchronized, and also requires adjusting them to a synchronized state through software program when the two massage components 1 are out of sync.

[0074] To monitor the motion state of the massage component 1, a sensor (i.e., a sensing component) needs to be added to the massage component 1 to monitor the swing position and swing speed of the first massage part 15 and the second massage part 16 on the massage component.

[0075] In this embodiment, the sensing component includes a movable sensing element that moves with the first massage unit 15 or the second massage unit 16, and a fixed sensing element. The swing position and swing speed of the first massage unit 15 and the second massage unit 16 are monitored by the relative position change between the movable sensing element and the fixed sensing element. Specifically, a Hall sensor can be selected, wherein the movable sensing element is a magnet and the fixed sensing element is a Hall switch. When the magnet passes the position of the Hall switch, the Hall switch will conduct and send a signal. Therefore, such a sensing element can monitor the swing position and swing speed of the massage component 1. In this embodiment, the movable sensing element is disposed on the tilting wheel 19, and the fixed sensing element is disposed on the fixed plate 183.

[0076] The specific procedure is as follows: Rotate the oscillating wheel 19 to the position where the moving sensing element aligns with the fixed sensing element, setting this as the initial position of the massage component 1. At this point, the Hall switch is in the on state. When the massage component 1 moves to the position where the Hall switch is on, it is determined that the massage component 1 is in the initial position, thus facilitating the reset of the massage component 1. This ensures that both massage components 1 start massaging from the same position; otherwise, even if the rotation speeds of the two massage components 1 are the same, if their starting positions are different, a synchronized massage effect cannot be achieved. Monitoring the oscillation speed can be done by monitoring the time interval between two Hall switch activations. Since the time interval between two Hall switch activations can be considered as the time it takes for the massage component 1 to complete one full massage cycle, the time required for the massage component 1 to complete one complete massage action can be collected. If the times are inconsistent, it can be determined that the two massage components 1 are not operating synchronously. Alternatively, the synchronization can be determined by monitoring the time taken for multiple consecutive complete massage actions and comparing the average time taken for each massage action of the two massage components 1, thus reducing the occurrence of errors.

[0077] Example 2

[0078] refer to Figure 19 The difference between this embodiment and Embodiment 1 is that the massage component 1611 in Embodiment 1 uses a massage plate + massage protrusions, while Embodiment 2 uses a massage plate + airbag. The same kneading massage effect can be achieved. The rest is the same as in Embodiment 1 and will not be described again.
