[0067] In the embodiment of the present disclosure, the massage device 100 includes a shell 10, a massage mechanism 30 and a drive mechanism 20. As shown in Figures 1 to 3 and Figure 8, the shell 10 is provided with a cavity 10A, the massage mechanism 30 and the drive mechanism 20 are arranged in the cavity 10A, the drive mechanism 20 is connected to the massage mechanism 30, and the drive mechanism 20 is configured to drive at least part of the massage mechanism 30 to drive the shell 10 to perform telescopic movement.

[0068] The massage device 100 of the technical solution disclosed in the present invention includes a shell 10 having a cavity 10A and a massage mechanism 30 and a drive mechanism 20 arranged in the cavity 10A. The massage mechanism 30 is connected to the drive mechanism 20. The drive mechanism 20 is configured to drive at least a part of the massage mechanism 30 to move to drive the shell 10 to perform telescopic movement, so that the relative length of the massage device 100 and the shell 10 can be changed. The telescopic change of the length is configured to dynamically stimulate acupuncture points and improve the comfort of massage.

[0069] It should be noted that when the movable part 50 moves relative to the track groove 50A, one end of the massage mechanism 30 is stationary relative to the shell 10, and the other end is movably connected to the driving mechanism 20. The output shaft of the driving mechanism 20 is connected to the other movable end of the massage mechanism 30. The driving mechanism 20 drives the other movable end along the Z axis to move relatively closer to or away from the stationary end to achieve the telescopic effect of the massage mechanism 30. The external state during the telescopic process can be shown in Figures 9 and 10.

[0070] 1 , 2 and 8 , optionally, the housing 10 is made of a flexible material, such as, for example, a silicone member, a rubber member, a plastic member, etc., and the middle section of the housing 10 is configured as a telescopic section 11 .

[0071] In this embodiment, the massage device 100 of the present application can be configured as a standard massage device or a miniature massage device, particularly a compact, lightweight, and portable massage device. The housing 10 is made of a flexible silicone material, for example. The flexible silicone material is both elastic and non-toxic, and will not harm the human body. The drive device and massage mechanism 30 provide an automatic retractable impact function. The automatic change in retractable length allows for dynamic and continuous contact with or separation from acupoints, thereby stimulating the acupoints and achieving a more physiologically effective massage effect.

[0072] As shown in Figure 8, the housing 10 includes a stationary section 12 and a push section 13 at each end, and a telescopic section 11 in the middle. The stationary section 12 is relatively stationary, while the push section 13 is pushed by the telescopic movement of the massage mechanism 30. The telescopic section 11 is an elastic pleated area, configured to extend and follow the movement of the push section 13 when it is pushed. When the push section 13 retracts, the telescopic section 11 returns to the pleated area.

[0073] As shown in Figure 8, the cavity 10A in the shell 10 includes a first cavity 101A, a second cavity 102A and a telescopic cavity 103A that are connected to each other. The movable connection part of the massage mechanism 30 is located in the telescopic cavity 103A covered by the telescopic section 11, and the corresponding static section 12 is accommodated in the first cavity 101A, and the push section 13 is accommodated in the second cavity 102A, so that the push section 13 can move with the massage mechanism 30 when one end of the massage mechanism 30 performs telescopic movement, thereby avoiding the length of the telescopic movement from causing tearing to the shell 10 or avoiding the shell 10 limiting the telescopic movement stroke, thereby improving the reliability of the telescopic movement.

[0074] The extension and retraction direction of the massage mechanism 30 is defined as the Z-axis direction. The main body of the massage mechanism 30 is detachable in half, and the disassembly direction is set as the X-axis direction. The direction perpendicular to the Z-axis and the X-axis is the Y-axis. The intersection of the X-axis, Y-axis and Z-axis is the origin O, and the three axes and the origin O together form a spatial rectangular coordinate system O-XYZ. The following description of each embodiment will use this coordinate system as the orientation standard, and the orientation reference is specifically shown in Figures 3 to 6.

[0075] 2 and 3 , the massage mechanism 30 optionally includes a fixed member 40 and a movable member 50, with the drive mechanism 20 mounted on the fixed member 40. The movable member 50 is provided with a movable chamber 50B, into which at least a portion of the fixed member 40 and the drive mechanism 20 movably extend, and the output shaft of the drive mechanism 20 is movably connected. The drive mechanism 20 drives the movable member 50 to cause the housing 10 to extend and retract relative to the fixed member 40.

[0076] In this embodiment, the massage mechanism 30 includes a fixed member 40 and a movable member 50 that are relatively movably connected. The fixed member 40 and the movable member 50 slide relative to each other along the Z-axis to achieve the telescopic function. Specifically, the fixed member 40 is disposed within the first cavity 101A and is stationary relative to the stationary section 12 of the housing 10. The movable member 50 is disposed within the second cavity 102A and abuts the push section 13 of the housing 10, performing synchronous telescopic movement.

[0077] 6 , the drive mechanism 20 optionally includes a drive member 21 and a transmission member 22 . The drive member 21 is mounted on the fixed member 40 . The transmission member 22 is connected to the output shaft and is located in the movable chamber 50B. The transmission member 22 has at least one transmission portion 221 .

[0078] Optionally, the transmission member 22 has two transmission parts 221 ; the two transmission parts 221 are symmetrically protruded on the outer peripheral side of the transmission member 22 with respect to the extension direction of the movable member 50 ; the extension direction of each transmission part 221 is perpendicular to the extension direction of the movable member 50 .

[0079] In this embodiment, the drive mechanism 20 includes a fixed drive member 21 and a movable transmission member 22. The drive member 21 is mounted on and restrained by the fixed member 40. The output shaft of the drive member 21 is disposed through an opening in the fixed member. One end of the transmission member 22 is connected to the output shaft of the drive member 21, and the other end is movably connected to the movable member 50. Specifically, the end of the transmission member 22 and the fixed member 40 adjacent to the movable member 50 extends into the movable chamber 50B of the movable member 50, and the transmission member 22 is movably connected to the inner wall of the movable chamber 50B.

[0080] Driven by the driver 21, the transmission member 22 moves, and this movement causes the movable member 50 to move relative to the fixed member 40 along the Z-axis. The driver 21 can be a stepper motor or a servo motor with adjustable speed. The motor's axis of rotation is parallel to the Z-axis. The transmission member 22 rotates in the same direction as the motor's output shaft, that is, the transmission member 22 rotates within the O-XY plane. The rotation of the transmission member 22 causes the movable member 50 to reciprocate up and down along the Z-axis relative to the transmission member 22 and the fixed member 40. As a result, the movable member 50 drives the push section 13 of the housing 10 toward or away from the stationary section 12 along the Z-axis, thereby achieving the telescopic function of the massage device 100.

[0081] Optionally, the massage mechanism 30 is a hard structural component.

[0082] In this embodiment, the massage mechanism 30 is a hard structural component, that is, the movable component 50 and the fixed component 40 are hard structural components. The hard structure makes the movable component 50 and the fixed component 40 of the massage mechanism 30 rigid, facilitates relative movement, and the movement trajectory is smooth and reliable.

[0083] It is understandable that the movable part 50 and the fixed part 40 of the massage mechanism 30 can be plastic parts, hard silicone parts or rubber parts, or other hard structures such as polymer resins, and their materials are not limited here.

[0084] 4 to 6 , optionally, a first guide portion 53 is formed on the inner wall of the movable bin 50B; a second guide portion 43 is provided on the outer periphery of the portion of the fixing member 40 extending into the movable bin 50B, and the first guide portion 53 is slidably connected to the second guide portion 43 along the telescopic direction.

[0085] In this embodiment, the movable member 50 is provided with a first guide portion 53 extending along the Z-axis. The portion of the fixed member 40 that extends into the movable compartment 50B is provided with a second guide portion 43. The second guide portion 43 corresponds to the first guide portion 53 and extends along the Z-axis. The first guide portion 53 and the second guide portion 43 slidably cooperate to limit the relative displacement of the movable member 50 and the fixed member 40 along the Z-axis, thereby achieving telescopic function along the Z-axis.

[0086] Furthermore, the first guide portion 53 and the second guide portion 43 can be set as a sliding cooperation mode of a guide groove and a guide rail, or can be set as a cooperation mode of a slider and a slide rail, or can be set as at least two guide strips respectively, and the guide strips of the first guide portion 53 and the second guide portion 43 are respectively staggered, so that when the movable part 50 contacts the fixed part 40, the two adjacent guide strips of the first guide portion 53 can limit one of the guide strips of the second guide portion 43, preventing the movable part 50 and the fixed part 40 from relative movement or rotation along the O-XY plane, thereby improving the reliability of the effective movement of the driving mechanism 20 as a telescopic movement.

[0087] It is understood that the massage device 100 can achieve the telescopic function by the drive member 21 extending and retracting along the Z-axis direction and driving the movable member 50 to move. In addition, the telescopic function of the massage device 100 can also be achieved by the drive member 21 directly driving the movable member 50 to move.

[0088] In the embodiment, the telescopic function is achieved by the movement of the driving member 21 driving the movable member 50. The driving member 21 is a linear motor, and the output shaft of the driving member 21 can move up and down along the Z-axis relative to the body of the driving member 21, that is, the moving part when the linear motor is driven is the output shaft, and the output shaft moves linearly. Specifically, the output shaft of the driving member 21 is fixedly connected to the movable member 50, so that the positional relationship between the movable member 50 and the output shaft is relatively static. The linear motor drives the output shaft to move up and down along the Z-axis, and the movable member 50 is driven by the driving shaft to move synchronously and in the same direction, thereby realizing the up and down telescopic movement of the movable member 50 along the Z-axis.

[0089] The telescopic function is achieved by the movement of the driving member 21 driving the movable member 50 to move.

[0090] The driving member 21 is configured as a servo motor, the transmission member 22 is configured as a screw, and the movable member 50 is threadedly connected to the screw. The motor output rotation causes the screw to rotate, and the rotation of the screw drives the movable member 50 to move up and down along the Z axis relative to the screw. During this movement, the servo motor connected to the screw needs to frequently rotate forward and reverse to enable the movable member 50 to drive the push section 13 of the shell 10 to reciprocate along the Z axis.

[0091] Optionally, the inner wall of the movable bin 50B is provided with a track groove 50A, and the structure of the track groove 50A is shown in Figures 4, 5 and 7; the output shaft of the driving mechanism 20 is provided with a transmission part 221, and the transmission part 221 is movably connected to the track groove 50A. The driving mechanism 20 drives the transmission part 221 to move along the track groove 50A to drive the movable part 50 to slide back and forth and extend relative to the fixed part 40.

[0092] In this embodiment, a track groove 50A is defined in the movable member 50, and the transmission member 22 of the drive mechanism 20 is connected to the track groove 50A of the movable member 50 via a transmission portion 221. The transmission member 22 is configured as a transmission disc, and the transmission portion 221 is disposed radially outwardly of the transmission disc. The transmission disc extends into the movable compartment 50B of the movable member 50 and is movably connected to the movable member 50.

[0093] The track groove 50A has a predetermined track, and the transmission part 221 extends into the track groove 50A. The transmission disc drives the transmission part 221 to move relative to the track groove 50A, so that the movable part 50 moves relative to the transmission part 221 through the track groove 50A. The transmission part 221 is arranged perpendicular to the Z axis and extends into the track groove 50A in a direction perpendicular to the Z axis. The driving member 21 drives the transmission disc to rotate in the O-XY plane. The relative height position of the transmission disc and the driving member 21 along the Z axis remains unchanged, so that the transmission disc does not need to move up and down relative to the driving member 21 in the Z axis, thereby improving the driving stability. In addition, because the first guide part 53 and the second guide part 43 are extended in the Z axis direction, the movable part 50 and the fixed part 40 cannot have a rotation function along the O-XY plane, and can only move relatively close to or away from each other along the Z axis to achieve a relative telescopic function.

[0094] The external state of the movable member 50 during its movement relative to the track groove 50A is shown in Figures 9 and 10 . Specifically, when the transmission disc rotates, the transmission portion 221 rotates with the transmission disc within the O-XY plane. When the transmission disc does not change height along the Z axis, the transmission portion 221 moves relative to the groove wall within the track groove 50A, causing the movable member 50 to move relative to the fixed member 40 along a predetermined trajectory. Based on the guidance provided by the first guide portion 53 on the inner wall of the movable chamber 50B of the movable member 50 and the second guide portion 43 on the outer periphery of the fixed member 40, the movable member 50 reciprocates up and down along the Z axis relative to the fixed member 40, thereby achieving the telescopic function of the movable member 50. This provides a simple driving structure and a stable driving process.

[0095] The track groove 50A forms a predetermined track, which improves the orderliness of the relative movement of the movable part 50 with the driving mechanism 20. At the same time, the setting of the predetermined track and the two guide parts makes the telescopic movement of the movable part 50 orderly and reliable, so as to realize the function of stimulating acupoints through the telescopic movement, thereby improving the reliability of contact with physiological acupoints and the comfort of massage.

[0096] Optionally, the track groove 50A is an annular groove.

[0097] In this embodiment, the track groove 50A provided on the cavity wall of the movable bin 50B of the movable part 50 is an annular groove, and the annular surface of the annular groove is arranged perpendicular to the Z axis. The transmission disk rotates around the Z axis, and the movable part 50 performs telescopic movement along the Z axis through the relative movement between the transmission part 221 and the track groove 50A. The setting of the annular groove allows the extension or retraction of the telescopic part to be achieved under the condition of driving in one direction. For example, the annular track groove 50A is connected end to end, so that the driving direction can be in one direction, such as the driving part 21 rotates clockwise to drive the transmission disk to rotate clockwise. During the entire telescopic movement, there is no need for the driving part 21 to change the driving direction. It can be understood that there is no need to change to clockwise drive, which improves the driving smoothness of the driving part 21 and the continuity of the telescopic drive, and can also extend the service life of the motor in disguise.

[0098] Optionally, the track groove 50A is arranged in a wave shape, and the wave-shaped track groove 50A has at least one wave crest 501 and at least one wave trough 502 , and a wave crest 501 and a wave trough 502 are connected at the end.

[0099] In the embodiment, as shown in Figures 4, 5, and 7, the track groove 50A moves relative to the transmission member 22 as the transmission member 22 rotates, causing the movable member 50 to move relative to the movable member 50 along the predetermined trajectory of the track groove 50A. The track groove 50A is arranged in a wavy shape, and the wavy track grooves 50A are connected end to end on the movable member 50 to form a circumferentially distributed wavy annular groove, which is the predetermined trajectory.

[0100] The wavy track groove 50A has at least one crest 501 and at least one trough 502, with each crest 501 and trough 502 converging and extending upward and downward along the Z-axis. The ends of the crest 501 extend downward, while the ends of the trough 502 extend upward, forming a closed annular track groove 50A. When the driver 21 rotates, the transmission portion 221 of the transmission member 22 repeatedly passes through the crests 501 and troughs 502. The driver 21 does not need to change its driving direction to achieve repeated up and down motion of the movable member 50 along the Z-axis, resulting in a simple structure and stable drive.

[0101] In the embodiment, the track groove 50A is arranged in a wave shape, and the wave-shaped track groove 50A has at least two wave crests 501 and at least two wave troughs 502 , and a wave crest 501 and a wave trough 502 are arranged alternately.

[0102] Specifically, the wavy track groove 50A has at least two crests 501 and at least two troughs 502, alternating between a crest 501 and a trough 502. The crests 501 and troughs 502 extend toward the Z-axis. The crest 501, trough 502, and crest 501, 502, are distributed along the circumference of the movable member 50. This allows the transmission portion 221 of the transmission member 22 to repeatedly pass through the crests 501 and troughs 502 during rotation of the driving member 21. This allows the movable member 50 to achieve repeated up and down motion along the Z-axis without changing the driving direction of the driving member 21, resulting in a simple structure and stable drive.

[0103] It can be understood that the driving member 21 is configured as a servo motor with adjustable speed, which drives the transmission disk to rotate in the O-XY plane, so that the movable member 50 performs a reciprocating telescopic motion up and down along the wave trajectory of the wave ring groove in the Z axis.

[0104] In one structural form of the track groove 50A, the wave-shaped track groove 50A has at least one wave crest 501 and at least one wave trough 502 .

[0105] The sinusoidal curve composition of the rectangular coordinate system can be referred to, and the middle position is defined as the initial position. A wave crest 501 and a wave trough 502 are connected end to end to form a closed annular track groove 50A, which can enable the movable part 50 to achieve an up and down reciprocating motion in one circular rotation of the transmission disk.

[0106] When the driving member 21 rotates in a circular direction once, it can realize a reciprocating extension and contraction process of the movable member 50 of "middle-up-middle-down-middle". The continuous driving rotation of the driving member 21 provides a complete repeated extension and contraction function, providing extension and contraction stimulation to the acupuncture points to achieve a massage effect.

[0107] In another structural form of the track groove 50A, the wave ring groove is provided with at least two wave crests 501 and wave troughs 502, which can enable the movable part 50 to realize two up and down reciprocating motions in one circular rotation of the transmission disk. The number of circumferential rotations is reduced while the number of reciprocating telescopic movements is doubled, thereby improving the telescopic drive efficiency.

[0108] 7 , optionally, a limiting platform 50C is formed on the inner wall of the movable bin 50B, and the limiting platform 50C is spaced apart from the track groove 50A; a limiting ring 45 is provided at the end of the fixing member 40 extending into the movable bin 50B, as shown in FIG3 and FIG6 , the limiting ring 45 is movable along the telescopic direction and limited to the limiting platform 50C.

[0109] In this embodiment, the track groove 50A is provided on the inner wall of the movable bin 50B, the relative positions of the fixing member 40 and the driving member 21 are fixed, and the relative height position of the transmission disk along the Z axis is also fixed. The rotation of the transmission disk drives the movable member 50 to perform an up and down reciprocating telescopic movement along the Z axis through the relative movement between the transmission part 221 and the track.

[0110] The movable bin 50B is sealed at one end and open at the other. One end of the fixed member 40 extends into the movable bin 50B through the opening. The inner wall of the movable bin 50B is provided with the aforementioned track groove 50A. A stopper 50C is also provided, spaced from the track groove 50A. The stopper 50C is positioned adjacent to the open end. A transmission disc extends into the movable bin 50B simultaneously with one end of the fixed member 40. A stopper ring 45 is provided at the end of the fixed member 40 adjacent to the transmission disc. The stopper ring 45 protrudes from the outer periphery of the end, allowing the stopper ring 45 to be constrained along the Z-axis within the space of the movable bin 50B on the side of the stopper 50C facing away from the opening of the movable bin 50B. The provision of the stopper ring 45 prevents the fixed member 40 from slipping out of the movable bin 50B during the relative telescopic motion with the movable member 50, thereby improving the stability and reliability of the telescopic motion.

[0111] It is understandable that the limiting ring 45 can be an annular protrusion provided at one end of the fixing member 40, and the fixing member 40 is an integrated structure including a fiber ring. The limiting ring 45 can also be an annular structure sleeved on one end of the fixing member 40, and the limiting ring 45 and the fixing member 40 are detachably sleeved. The present disclosure is preferably a fixing member 40 with an integrated structure. The circumference of the limiting ring 45 is parallel to the O-XY plane, and the first guide portion 53 and the second guide portion 43 are arranged parallel to the Z axis. One end of the second guide portion 43 extends to the annular surface of the limiting ring 45, so that the telescopic movement of the end of the fixing member 40 extending into the movable bin 50B can be fully guided by the second guide portion 43 on the Z axis, so that the telescopic movement is stable and sustainable.

[0112] 6 , optionally, the fixing member 40 is provided with a limiting bin 41A for accommodating the driving mechanism 20, and a locking groove 41B is recessed on the inner wall of the limiting bin 41A; a locking portion 211 is formed on the outer periphery of the driving mechanism 20, and the locking portion 211 is locked and limited in the locking groove 41B along the telescopic direction.

[0113] In this embodiment, the driving member 21 of the drive mechanism 20 is fixed relative to the fixed member 40, and the output shaft of the driving member 21 is connected to the transmission member 22. The fixed member 40 is provided with a limiting chamber 41A, which is configured to accommodate and limit the driving member 21. The inner wall of the limiting chamber 41A is recessed with a retaining groove 41B. The outer shell of the driving member 21 is formed with a retaining portion 211, which is retained and engaged in the retaining groove 41B to spatially limit the driving member 21 along the X-axis, Y-axis, and Z-axis. This ensures that the driving member 21 is immobilized relative to the fixed member 40, improving the driving stability of the driving member 21.

[0114] It is understood that the retaining groove 41B is recessed into the inner wall of the retaining chamber 41A in the form of an irregular polygonal groove, or a regular V-shaped groove, a convex groove, a rectangular groove, or other polygonal groove, to restrict its rotation within the O-XY plane. The retaining chamber 41A has a through-hole on the end facing the movable member 50, which is located inside the retaining ring. The output shaft of the driver 21 extends from the through-hole and connects to the transmission disk. The driver 21 is restrained along the Z-axis by the upper surface of the retaining groove 41B or by the retaining ring 45, thus ensuring a stable structural arrangement of the driver 21.

[0115] 3 and 6 , the fixing member 40 optionally includes a limiting segment 41 and a mounting segment 42. The limiting segment 41 extends into the movable chamber 50B. A limiting chamber 41A having a through opening is disposed within the limiting segment 41. One end of the driving mechanism 20 is disposed within the limiting chamber 41A, and the other end extends from the through opening to connect to the transmission portion 221. The mounting segment 42 is disposed at the end of the limiting segment 41 away from the movable member 50. The mounting segment 42 is located at one end of the cavity 10A and is detachably connected to the housing 10.

[0116] In this embodiment, the fixing member 40 includes a limiting section 41 and a mounting section 42. The limiting section 41 extends into the movable chamber 50B and moves relative to the movable member 50 along the Z-axis direction within the movable chamber 50B. A limiting chamber 41A is provided in the limiting section 41, and the output shaft of the driving member 21 extends from the opening of the limiting chamber 41A to connect to the transmission member 22. A limiting ring 45 is provided protrudingly at one end of the limiting section 41 away from the mounting section 42, and a second guide portion 43 is provided on the outer peripheral wall of the limiting section 41 along the Z-axis direction. The mounting section 42 is provided at one end of the limiting section 41 away from the movable member 50, and the mounting section 42 is detachably connected to the housing 10 to secure the fixing member 40 to the stationary section 12 of the housing 10. One end of the movable part 50 away from the fixed part 40 is detachably fixed to the push section 13 of the shell 10, so that the relative expansion and contraction of the movable part 50 and the fixed part 40 drives the stationary section 12 and the push section 13 of the shell 10 to move closer to or away from each other, causing the expansion and contraction section 11 to stretch or contract, thereby realizing the expansion and contraction function of the entire massage device 100.

[0117] It is understood that the limiting section 41 is a hollow cylindrical structure with an opening at one end, the hollow portion of the cylinder forming the limiting chamber 41A, and the mounting section 42 is a hollow spherical structure. The mounting section 42 may be integrally formed with the limiting section 41 or detachably connected to the limiting section 41. A limiting ring 45 protrudes from the end of the cylindrical limiting section 41 away from the mounting section 42. The limiting ring 45 may be integrally formed with the limiting section 41, such as by injection molding; the mounting section 42 may also be detachably assembled with the limiting section 41.

[0118] Furthermore, the outer periphery of the driving member 21 of the driving mechanism 20 is provided with a retaining portion 211. The outer periphery of the retaining portion 211 is configured as a non-circular structure. For example, the outer contour of the retaining portion 211 is configured as a rectangular structure. The corresponding wall of the limiting chamber 41A is concavely configured to match the shape of the retaining portion 211, thereby limiting the vertical movement of the driving member 21 along the Z axis and the rotation along the O-XY plane, thereby ensuring the stability of the configuration of the driving member 21. The output shaft of the driving member 21 extends out of the limiting chamber 41A through the opening and is detachably connected to the transmission member 22 located at the outer end of the limiting chamber 41A. The transmission portion 221 of the transmission member 22 is movably disposed within the track groove 50A, which is a wavy annular groove. Under the guidance of the first guide portion 53 and the second guide portion 43, the driving member 21 drives the transmission portion 221 on the transmission disk to drive the movable member 50 to move up and down along the predetermined trajectory of the track groove 50A.

[0120] In this embodiment, the power supply assembly 70 can be independently housed within the cavity 10A or integrated with the massage mechanism 30, optimizing the structural footprint and making the miniature massage device 100 even smaller. The power supply assembly 70 includes a battery 71 and a main control board. The main control board and the drive mechanism 20 are electrically connected to the battery 71, and the drive mechanism 20 is electrically and signal-connected to the main control board.

The troughs 502 of the left half shell 51 and the right half shell 52 are also arranged opposite each other. A trough 501 and a trough 502 are alternately arranged to form a complete wavy track groove 50A to support the movable part 50 to realize two reciprocating telescopic operations in one circular drive of the driving part 21.
