[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Reference Figures 1-8 As shown.

[0018] A massager includes: a motor 1, a transmission assembly 2, a housing 3, and a plurality of massage rods 4; The rotating shaft of the motor 1 is the first rotating shaft; The massage rod 4 is divided into a connecting section 41 and a massage section 42; The axis of the connecting segment 41 forms a second rotation axis, which is perpendicular to the first rotation axis. The length direction of the massage segment 42 forms an angle with the second rotation axis; The plurality of massage rods 4 are arranged sequentially along the first rotation axis; The motor 1 drives multiple massage rods 4 to rotate around the second rotation axis via the transmission assembly 2.

[0019] In the prior art, there is a massager with auxiliary massage heads protruding from the circumferential wall of the main body 7. These auxiliary massage heads oscillate (moving closer or further apart) to provide pinching stimulation to the area to be massaged. Another type of massager uses auxiliary massage heads on the same principle, but with larger openings and a wider swing amplitude. When oscillating, these auxiliary massage heads create a pinching motion, thus pinching the entrance to the area to be massaged. All prior art provides auxiliary massage heads that oscillate. Furthermore, there is a rotary massager where the front end of the massager can rotate, exhibiting a conical motion trajectory. This rotary massager rotates in the same direction continuously, eliminating the need for direction changes compared to the aforementioned oscillating motion. Therefore, this rotary motion is smoother, less prone to jamming, and the circular motion trajectory covers a much larger massage area than the reciprocating oscillating trajectory. However, rotary massagers are all driven by a motor directly connected to a rotating rod, thus only one rotating rod can be driven, and therefore, squeezing or pinching motions are not possible.

[0020] This application provides a novel type of massager that achieves a pinching action through rotational motion. Firstly, the rotating shaft of motor 1 serves as the first rotating shaft. This application includes multiple massage rods 4, each having a massage section 42 and a connecting section 41. The axis of the connecting section 41 serves as the second rotating shaft, which is perpendicular to the first rotating shaft. Due to the limitations of the basic shape of an in-body massager, the rotating shaft of motor 1 typically needs to be parallel to the length direction of the massager. In this application, as... Figure 3 As shown, the entire massage rod 4 can be divided into a connecting section 41 and a massage section 42. Specifically, the massage rod 4 can be understood as a rod divided into two sections: the connecting section 41 and the massage section 42. The axis of the connecting section 41 serves as the second rotation axis, which is perpendicular to the first rotation axis, allowing the massage rod 4 to rotate around the second rotation axis. The massage section 42 protrudes from the circumferential wall of the massager body 7, allowing the end of the massage section 42 to press against the side wall of the massaged area when the massager body 7 massages the area to be massaged. Furthermore, in this application, the length direction of the massage section 42 forms an angle with the second rotation axis, meaning the massage section 42 is inclined. Therefore, the massage rod 4 can be understood as a bent rod, with the bent side being the connecting section 41 and the other side being the massage section 42.

[0021] Since the first rotating axis is perpendicular to the second rotating axis, an additional transmission assembly 2 is required so that the motor 1 can drive multiple massage rods 4 to rotate through the transmission assembly 2.

[0022] The end of the massage segment 42 rotates around the second rotation axis. It is certain that the end of the massage segment 42 can rub and squeeze the area to be massaged, and the friction trajectory is circular. The friction trajectory formed by the massage segment 42 in this application and the arc trajectory formed by the swing of the massage rod 4 in the prior art are located in mutually perpendicular planes. The friction trajectory formed by the massage rod 4 in the prior art on the area to be massaged during the movement is a straight line or a rectangle. Therefore, the friction trajectory formed in the prior art is parallel to the massage direction of the massager body 7. In practice, it is only necessary to set a protrusion on the circumferential wall of the massager body 7 to achieve the same massage trajectory as the prior art. However, the massage rod 4 in the prior art is driven by the motor 1 and can swing rapidly. This swing speed is far beyond what can be achieved manually. Therefore, the massage rod 4 in the prior art performs high-frequency friction on a certain point on the inner wall of the area to be massaged.

[0023] Understandably, with massage rods 4 of the same size, the circular friction trajectory formed in this application, compared to the rectangular trajectory of the prior art, offers a larger massage range, especially in the width direction. While the difference in coverage in the length direction is not significant, it's important to note that the length direction is parallel to the movement direction of the massager body 7. Therefore, when the user uses the massager body 7, it will cause the massage rods 4 to move as well. The user's movement amplitude is much greater than the massage range of the massage rods 4, making the coverage range of the massage rods 4 in the length direction less important. Conversely, the width-direction coverage remains unchanged by the movement of the massager body 7. Only by rotating the massager body 7 can the massage range of the massage rods 4 in the width direction be increased. Understandably, rotating the massager body 7 is difficult and awkward for the human body and does not conform to the normal use of a massager. Therefore, increasing the width-direction coverage of the massage rods 4 is particularly challenging, and increasing the width-direction coverage of the massage rods 4 can significantly improve the massage experience. Furthermore, the circular motion trajectory applies different directions of force to the massaged areas, providing users with different massage experiences. In this application, multiple massage rods 4 are arranged along the direction of the first rotation axis, that is, there is at least one adjacent massage rod 4. It can be understood that setting multiple massage rods 4 can greatly increase the massage range. When the massager body 7 is not moving, the massage rods 4 can also fully cover one side wall of the part to be massaged, making it easier to cover the most sensitive points of the part to be massaged.

[0024] The massager also includes a housing 3, which is a cylindrical structure and extends along the first rotation axis for insertion into the area to be massaged. The connecting section 41 is rotatably connected to the housing 3, and the massage section 42 protrudes from the circumferential wall of the housing 3; The motor is fixedly connected to the end of the housing 3.

[0025] The housing 3 serves as the main support component in the massager. Its outer wall supports the flexible layer 5, thus forming the main body 7 of the massager. Simultaneously, the housing 3 also acts as a mounting frame for various components, determining their installation positions and connection relationships.

[0026] The connecting section 41 is rotatably connected to the housing 3, and the massage section 42 protrudes from the circumferential wall of the housing 3; that is, the massage section 42 protrudes from the circumferential wall of the massager body 7 of the massager.

[0027] like Figure 2 , Figure 3 As shown, the transmission assembly 2 specifically includes a reversing structure 21 and multiple transmission gears 22; the multiple transmission gears 22 are fixedly connected to the connecting section 41, and the multiple transmission gears 22 mesh with each other; One end of the reversing structure 21 is connected to the output shaft of the motor 1, and the other end is connected to a transmission gear 22, so that the motor 1 drives the transmission gear 22 to rotate.

[0028] First, the output direction of the motor 1 is changed by the reversing structure 21. The reversing structure 21 can use two bevel gears. One bevel gear is set in the output shaft of the motor 1 as the first bevel gear 211, and the other bevel gear is rotatably connected to the housing 3 as the second bevel gear (which can also be understood as the connecting section 41 that is fixedly connected to the massage rod 4, and the connecting section 41 is rotatably connected to the housing 3). The axis of the second bevel gear is parallel to the second rotation axis, that is, the first bevel gear 211 and the second bevel gear mesh perpendicularly to each other. The axis of the first bevel gear 211 is collinear with the first rotation axis, and the axis of the second bevel gear is perpendicular to the first rotation axis, thus forming the second rotation axis. Then, a transmission gear 22 is fixedly connected to each massage rod 4. The transmission gear 22 can be set as the most common spur gear. The spur gears set in adjacent massage rods 4 mesh with each other. If there is interference between adjacent massage rods 4, a massage rod 4 can be spaced between adjacent transmission gears 22. That is, a transmission gear 22 without a massage rod 4 can be set between adjacent massage rods 4, thereby increasing the spacing between the massage rods 4 and avoiding interference when the massage section 42 rotates.

[0029] Furthermore, the opening directions of the included angle formed by adjacent massage rods 4 are different.

[0030] The most preferred structure is that the opening directions of the included angles in adjacent massage rods 4 are opposite.

[0031] During rotation, the ends of two adjacent massage segments 42 will approach each other and compress, achieving a pinching massage effect. Specifically, the ends of the massage segments 42 compress the inner wall of the area to be massaged, causing deformation of the inner wall. However, the deformation of the inner wall around the ends of the massage segments 42 is smaller. When the included angles of the adjacent massage segments 42 are different, the two massage segments 42 will inevitably meet during rotation. At this time, the inner walls of the area to be massaged around the ends of the two massage segments 42 will overlap. This overlapping area is squeezed by the ends of the two massage segments 42, thus creating a pinching massage effect.

[0032] Furthermore, the massage segment 42 has a rotating part 421 to allow the massage segment 42 to roll and rub against the flexible layer 5.

[0033] In the massager of this application, the massage segment 42 continuously rotates around the second rotation axis. However, the flexible layer 5 covers the entire massager, and the flexible layer 5 obviously cannot rotate around the second rotation axis. During the rotation of the massage segment 42, there is a certain sliding friction resistance between the massage segment 42 and the inner wall of the flexible layer 5. The power provided by the motor 1 of the massager is not large to begin with. At this time, driving multiple massage segments 42 to rotate requires overcoming the resistance between these massage segments 42 and the flexible layer 5, which greatly increases the load on the motor 1, resulting in a decrease in the rotation speed of the massage segment 42 and a decrease in the battery life of the massager.

[0034] In this embodiment, a rotating part 421 is provided in the massage section 42. The rotating part 421 is in direct contact with the flexible part, thereby enabling rolling friction between the massage section 42 and the flexible layer 5, which greatly reduces frictional resistance. The rotating part 421 can be configured as a bearing, or simply a plastic ring can be rotatably connected in the massage section 42.

[0035] Furthermore, a vibration module 6 can be provided at the end of the massager body 7, so that the massager body 7 has a vibration effect, thereby providing vibration massage to the user. The vibration module 6 can be directly wrapped by the flexible layer 5.

[0036] Furthermore, the motor 1 is a geared motor 1, connected to a gearbox 11. This reduces the speed of the motor 1 to obtain greater torque.

[0037] Example 2 Reference Figures 1-6 As shown.

[0038] The massage rod 4 has two massage sections 42, which are located at both ends of the connecting section 41 respectively; the two massage sections 42 protrude from the side wall of the massager body 7 toward both ends of the second rotating shaft.

[0039] In existing massagers, the circumferential wall of the massager body 7 has numerous protrusions that massage the area to be massaged. The massage rod 4 of this application can provide high-frequency massage to the area to be massaged, so the massage effect is obviously much stronger than that of the protrusions. However, due to size limitations, the area to be massaged cannot completely cover the circumferential wall of the massager body 7. Therefore, this embodiment provides a massage rod 4 structure that can simultaneously massage both sides of the inner wall of the area to be massaged, without significantly altering the device's transmission structure or the product's volume.

[0040] Specifically, two massage segments 42 are provided in the massage rod 4, located at both ends of the connecting segment 41. The massage rod 4 can still be understood as a single rod, but in this embodiment, it is divided into three segments: the middle segment serves as the connecting segment 41, and the two ends serve as the massage segments 42. Both ends of the connecting segment 41 are bent, forming an angle. For the massage rod 4, only the connecting part needs to be rotated. Although the massage segments 42 are added in this embodiment, the connecting segment 41 remains unchanged. Therefore, the transmission mechanism, such as the transmission component 2, does not need any modification, and the motor 1 can still drive the massage rod 4 to rotate. This achieves massage of the wall surface in more directions on the area to be massaged with minimal changes to the massager's structure.

[0041] It should be noted that the three-section rod may not be able to be directly inserted into the hole of the housing 3. In this case, one of the massage sections 42 can be fixedly connected to the connecting section 41 by threads. First, insert the connecting section 41 into the housing 3, and then connect the massage section 42 into the connecting section 41.

[0042] Example 3 Reference Figures 1-5 as well as Figure 7 As shown, The massage rod 4 has only one massage segment 42, and the massage segments 42 of adjacent massage rods 4 protrude from the massager body 7 in different directions.

[0043] This embodiment still aims to expand the massage range of the massage rod 4. In embodiment 2, two massage segments 42 are set to achieve massage in two directions. The diameter of the massager body 7 is very limited, and the diameter of the transmission gear 22 set therein is also not very large. The distance between the massage rods 4 of adjacent transmission gears 22 is very small, but it is necessary to ensure that the movement trajectories of adjacent massage segments 42 do not interfere with each other. If the distance is not changed, then the movement trajectory of the massage segments 42 can only be reduced, that is, the angle can be reduced. However, reducing the movement trajectory of the massage segments 42 will inevitably weaken the massage effect of the massage rod 4. Therefore, it is not necessary to provide a massage rod 4 in every transmission gear 22. For example, with a first transmission gear 22, a second transmission gear 22, and a third transmission gear 22 meshing sequentially, a first massage rod 4 and a third massage rod 4 are respectively provided in the first and third transmission gears 22, with the massage segments 42 of the first and third massage rods protruding in the same direction. A second massage rod 4 is provided in the second transmission gear 22, with the massage segments 42 protruding in the opposite direction to the massage segments 42 of the first massage rod 4. A fourth, fifth, etc., can also be included.

[0044] The massage rod 4 in this structure and its arrangement are simpler than the two-section massage rod 4 structure in Embodiment 2. The structure of the massage rod 4 in this embodiment is exactly the same as that of the massage rod 4 protruding in a single direction. Only the shape of the flexible layer 5 needs to be changed, and the component structure does not need to be changed at all, so that two models of massagers can be produced, thereby gaining a wider user base without increasing costs.

[0045] Example 4 Reference Figure 8 As shown.

[0046] The reversing structure 21 includes a first cross helical gear 212 and a second bevel gear 213 and a second cross helical gear 214. The first cross helical gear 212 and the second bevel gear 213 are connected to the output shaft of the motor 1. The second cross helical gear 214 is coaxially and fixedly connected to one of the massage rods 4. The first cross helical gear 212 and the second bevel gear 213 mesh with the second cross helical gear 214.

[0047] This embodiment provides a different form of reversing structure 21. The reversing structure 21 consists of two crossed helical gears. The first crossed helical gear 212 and the second bevel gear 213 are connected to the output shaft of the motor 1. The first crossed helical gear 212 and the second bevel gear 213 are coaxially connected to the output shaft of the motor 1 and rotate with the output shaft. The second crossed helical gear 214 is connected to the massage rod 4, and the second crossed helical gear 214 and the connecting section 41 of the massage rod 4 are coaxial. The first crossed helical gear 212 and the second bevel gear 213 mesh with each other. The rotation of the output shaft of the motor 1 drives the first crossed helical gear 212 and the second bevel gear 213 to rotate. The meshing of the first crossed helical gear 212 and the second bevel gear 213 with the second crossed helical gear 214 causes the second crossed helical gear 214 to rotate, ultimately driving the massage rod 4 to rotate.

[0048] A crossed helical gear (also known as an interleaved shaft helical gear or a spiral gear pair) is a gear mechanism used for non-parallel, non-intersecting shaft transmissions. It consists of two helical gears with opposite helix angles, and their axes are spatially intersecting (usually 90°). That is, the second crossed helical gear 214 is perpendicular to the first crossed helical gear 212 and the second bevel gear 213, thus forming a second rotating shaft perpendicular to the first rotating shaft. This achieves the basic function of the reversing structure 21.
