Description

Technical Field

[0001] The present invention relates to the technical field of massagers, in particular to a massager. Background Art

[0002] At present, people working in offices have the characteristics of long sitting time, little exercise, slow blood flow to the limbs, and serious damage to the waist and neck. With the development of society and the increasingly accelerated pace of life, people's work pressure is also increasing. In order to complete work tasks, people often need to work overtime. Therefore, after a day of intense work, people's bodies become tired. For example: long-term keyboarding can cause stiff finger joints, and long-term sitting can cause back pain, numbness in legs and feet, and swelling of ankle joints. In order to relieve fatigue, promote blood circulation in the human body, and ensure the health of office people as much as possible, people generally use massagers to massage their bodies during work or after get off work to promote blood circulation, such as using massagers to massage fingers, waist and legs.

[0003] The Chinese patent with publication number CN211461101U discloses a peristaltic structure and a massager, including a motor, a drive shaft connected to the motor, and a plurality of peristaltic plates sleeved on the drive shaft. When the motor is powered on, the motor drives the drive shaft to rotate and the plurality of peristaltic plates reciprocate along the radial direction of the drive shaft, thereby performing intermittent massage on the human body (such as limbs, hand braces, etc.). However, the plurality of peristaltic plates of the above massager are driven by a drive shaft. When a peristaltic plate is stuck and cannot move, the load on the drive shaft is easily increased and it is easy to get stuck, thereby causing other peristaltic plates to be unable to move normally.

[0038] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment discloses a massager 100, including a flexible sheath 110, a guide rod 120 with two ends, a handle 130, a plurality of peristaltic members 140, a stop assembly 150 and a drive assembly 160, wherein the plurality of peristaltic members 140 are rotatably sleeved on the guide rod 120, the handle 130 is connected to one end of the guide rod 120, and the stop assembly 150 is connected to the other end of the guide rod 120. The flexible sheath 110 covers the guide rod 120, the handle 130, the plurality of peristaltic members 140, the stop assembly 150 and the drive assembly 160, and the outer dimensions of the guide rod 120, the handle 130, the plurality of peristaltic members 140 and the stop assembly 150 are set to be compatible (similar in size).

[0039] like Figure 3 , Figure 4 As shown, a power transmission structure is provided between the peristaltic members 140 and the peristaltic members 140, and the driving assembly 160 is located at one end of the handle 130 and can drive the adjacent peristaltic members 140 to rotate. The power transmission structure can transmit power to the adjacent peristaltic members 140 after the peristaltic members 140 rotate at a preset angle, until the plurality of peristaltic members 140 rotate within the axial range limited by the limiting assembly 150. There is a clearance fit between the peristaltic members 140 and the guide rod 120. After the driving assembly 160 starts working, it will drive the connected peristaltic members 140 to rotate on the guide rod 120, and the power between the peristaltic members 140 is transmitted in sequence, so that the plurality of peristaltic members 140 rotate in sequence from bottom to top along the guide rod 120.

[0040] Specifically, Figure 5 , Figure 6As shown, the peristaltic member 140 is provided with two abutment plates 142, an offset hole 144, an eccentric block 145 and a convex stop 146. The offset hole 144 is radially opened on the symmetry line of the peristaltic member 140. Each peristaltic member 140 is sleeved on the guide rod 120 through the offset hole 144. The lateral width of the offset hole 144 is slightly larger than the diameter of the guide rod 120 so that the peristaltic member 140 can rotate around the guide rod 120 or / and move radially relative to the guide rod 120. The radial length of the offset hole 144 is greater than twice the diameter of the guide rod 120. After the guide rod 120 passes through the offset hole 144 of the peristaltic member 140, the peristaltic member 140 can move within the range defined by the offset hole 144, so that the peristaltic member 140 has space for lateral movement when rotating. The eccentric block 145 is convexly arranged on the upper end surface of the peristaltic member 140, and the two abutting plates 142 and the convex stopper 146 are convexly arranged on the lower end surface of the peristaltic member 140. The eccentric block 145 is radially arranged along the edge of the offset hole 144, the convex stopper 146 is located at one end of the offset hole 144 and on the symmetry line of the offset hole 144, and the two abutting plates 142 are symmetrically arranged on both sides of the other end of the offset hole 144. The eccentric block 145 includes (integrally formed in this embodiment) an arc segment 1451, two connecting segments 1452 and two abutting segments 1453, the arc segment 1451 is located at one end of the offset hole 144, the two connecting segments 1452 extend from both ends of the arc segment 1451 and connect one of the two abutting segments 1453, and the two abutting segments 1453 are separately located on both sides of the offset hole 144. During the rotation of the peristaltic member 140, after the peristaltic member 140 rotates by an angle, the arc segment 1451 in the eccentric block 145 first abuts against the convex stop 146 on the adjacent peristaltic member 140, causing the adjacent peristaltic member 140 to move laterally in one direction (the guide rod 120 changes position in the offset hole 144), and then the peristaltic member 140 continues to rotate by an angle until the transition segment 1452 and / or the abutment segment 1453 in the eccentric block 145 abuts against the abutment plate 142 on the adjacent peristaltic member 140, causing the adjacent peristaltic member 140 to rotate or / and simultaneously produce a small lateral movement in another direction (since the abutment segment 1453 in this embodiment is provided with a convex arc, the convex arc abuts against the abutment plate 142, causing the peristaltic member 140 to produce a small lateral displacement), at which time the adjacent peristaltic member 140 also rotates to complete the power transmission. The eccentric block 145, the convex stopper 146 and the abutment plate 142 cooperate with each other between two adjacent peristaltic members 140, so that the plurality of peristaltic members 140 rotate and move laterally on the guide rod 120 in sequence, and finally roll in a wave-like manner, thereby achieving a massage effect. Figure 4 , Figure 7 As shown, it illustrates the positional relationship between the peristaltic members 140 when the peristaltic members 140 are in a rotating state.

[0041] like Figure 4 , Figure 8As shown, the driving assembly 160 includes a transmission sheet 162 and a motor 164, the motor 164 is arranged in the handle 130, the transmission sheet 162 is provided with a second eccentric block 1621 and a first central through hole 1622, and the second eccentric block 1621 is arranged in the same size and position as the eccentric block 145 on the peristaltic member 140. The second eccentric block 1621 is arranged on the upper end surface of the transmission sheet 162, the transmission sheet 162 is rotatably sleeved on the guide rod 120 through the first central through hole 1622, and the second eccentric block 1621 is adapted to the abutment plate 142 on the adjacent peristaltic member 140. The limiting assembly 150 includes a pressing sheet 151 and a nut 152, the pressing sheet 151 is fixedly arranged on the guide rod 120 through the nut 152, and the pressing sheet 151 abuts against the peristaltic member 140 adjacent thereto.

[0042] Since a power transmission structure is provided between the peristaltic members 140 and the peristaltic members 140, the driving assembly 160 is located at one end of the handle 130 and can drive the adjacent peristaltic members 140 to rotate. The power transmission structure can transmit power to the adjacent peristaltic members 140 after the peristaltic members 140 rotate a preset angle, until several peristaltic members 140 rotate within the range limited by the limiting assembly 150. Therefore, this embodiment adopts a scheme in which the peristaltic members 140 transmit the peristaltic members 140 in sequence. There is no rigid fixed connection relationship between the peristaltic members 140 and the peristaltic members 140. Even if some peristaltic members 140 cannot rotate due to being stuck, other peristaltic members 140 can also rotate normally, which has the advantages of strong stability and good experience effect. Specific embodiment 2

[0044] like Fig. 9 , Fig.10 , Fig.11 As shown, this embodiment discloses another structural solution of a massager 100, including a flexible sheath 110, a guide rod 120 with two ends, a handle 130, a plurality of peristaltic members 140, a stop assembly 150 and a drive assembly 160, and four peristaltic spinous processes 143 are arranged on the periphery of each peristaltic member 140. A second central through hole 147 is arranged at the center of the peristaltic member 140, and the peristaltic member 140 is rotatably sleeved on the guide rod 120 in sequence through the second central through hole 147. The handle 130 is connected to one end of the guide rod 120, and the stop assembly 150 is connected to the other end of the guide rod 120. In this embodiment, the outer dimensions of the guide rod 120, the handle 130, the plurality of peristaltic members 140, and the stop assembly 150 match each other, and the flexible sheath also covers the guide rod 120, the handle 130, the plurality of peristaltic members 140, the stop assembly 150 and the drive assembly 160.

The power transmission structure can transmit power to the adjacent peristaltic members 140 after the peristaltic members 140 rotate at a preset angle, until a plurality of peristaltic members 140 rotate within the range limited by the limiting assembly 150. There is a clearance fit between the peristaltic members 140 and the guide rod 120. After the driving assembly 160 starts working, it will drive the peristaltic members 140 to rotate on the guide rod 120 in turn, so that a plurality of peristaltic members 140 rotate in turn from bottom to top along the guide rod 120, and the peristaltic spinous processes 143 on the peristaltic members 140 form a wave-like roll to achieve a massage effect.

[0046] Specifically, Fig.11 , Fig.12 As shown, the power transmission structure includes a paddle plate 141 and an abutment plate 142, which are respectively convexly arranged on the front and back end surfaces of the peristaltic member 140, and the paddle plate 141 abuts against the abutment plate 142 on the adjacent peristaltic member 140 after rotating at an angle. A convex block 161 is convexly arranged on the upper end surface of the driving component 160, and the convex block 161 abuts against the abutment plate 142 on the adjacent peristaltic member 140 after rotating at an angle.

[0047] like Fig.11 As shown, the limiting assembly 150 includes a pressing piece 151, a first bearing 152 and a pressure cover 153. A third central through hole 1512 is provided at the center of the pressing piece 151, and the pressing piece 151 is sleeved on the guide rod 120 through the third central through hole 1512. A transmission protrusion 1511 is convexly provided on the end surface of the pressing piece 151 close to the peristaltic member 140. After the peristaltic member 140 adjacent to the pressing piece 151 rotates an angle, the shift plate 141 on the peristaltic member 140 abuts against the transmission protrusion 1511. The first bearing 152 is provided between the pressing piece 151 and the pressure cover 153 to reduce the friction between the pressing piece 151 and the pressure cover 153. In this embodiment, the pressing piece 151 and the peristaltic member 140 are both concentrically arranged, and the pressure cover 153 is fixed on the guide rod 120 to limit the axial movement of the pressing piece 151 and the peristaltic member 140.

[0048] like Fig.10 , Fig.11 , Fig.13 As shown, the driving assembly 160 in this embodiment includes a transmission piece 162, a second bearing 163, a motor 164 and a reducer 165. The transmission piece 162 is rotatably arranged on the guide rod 120 through the second bearing 163, and the transmission piece 162 is located at one end of the handle 130. The upper end surface of the transmission piece 162 is provided with a protrusion 161, and the transmission piece 162 can be connected to the adjacent peristaltic member 140 through the protrusion 161 to achieve power transmission with the adjacent peristaltic member 140.

[0049] like Fig.10As shown, the reducer 165 is connected between the transmission plate 162 and the motor 164, and the reducer 165 is selected as a gear-type multi-stage reducer. The output shaft of the motor 164 is connected to the small gear in the reducer 165, and the output shaft of the motor 164 drives the transmission plate 162 to rotate by connecting the reducer 165. The reducer 165 is fixedly arranged in the handle 130, and the second bearing 42 is arranged between the reducer 165 and the transmission plate 162. The lower port of the transmission plate 162 is provided with meshing teeth 1623, and the output gear of the reducer 165 is connected to the meshing teeth 1623 on the transmission plate 162. In other embodiments, the reducer 165 can also be selected as other types of reducers, such as a worm reducer.

[0050] In other embodiments, Fig.14 As shown, the arrangement of the drive assembly 160 can be changed to: the drive assembly 160 includes a transmission sheet 162, a second bearing 163 and a motor 164, the transmission sheet 162 is fixedly arranged on the guide rod 120, the upper end surface of the transmission sheet 162 is provided with a convex block 161, the motor 164 is arranged in the handle 130, the guide rod 120 is rotatably connected to the handle 130 through the second bearing 163, and the motor 164 can drive the guide rod 120 to rotate relative to the handle 130.

The power transmission structure can transmit power to the adjacent peristaltic members 140 after the peristaltic members 140 rotate a preset angle, until several peristaltic members 140 rotate within the range limited by the limiting assembly 150. Therefore, this embodiment adopts a scheme in which the peristaltic members 140 transmit the peristaltic members 140 in sequence. There is no rigid fixed connection relationship between the peristaltic members 140 and the peristaltic members 140. Even if some peristaltic members 140 cannot rotate due to being stuck, other peristaltic members 140 can also rotate normally, which has the advantages of strong stability and good experience effect.

[0052] According to the description of the above embodiments, those skilled in the art should know that the same type of components may have different shapes in different embodiments due to the combination, lack or slight change of functions. For example, the peristaltic member 140 has different shapes in the specific embodiment 1 and the specific embodiment 2, and the massage effects are different, but the main function is peristalsis, so the same number is used in the context of distinguishing the specific embodiments.
