Additionally, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously.

[0032] See Figures 1 to 3 The massager 10 of this utility model includes a housing 100, a drive mechanism 200 disposed inside the housing 100, and a ball bearing portion 120 disposed on the housing 100.

[0033] like Figure 1-3 As shown, the housing 100 includes a main body 110, which is generally elongated and rod-shaped. A first massage part 112 is formed at the front end of the main body 110, and a handheld part 116 is formed at the rear end. In use, the user holds the handheld part 116 to deliver the first massage part 112 to the area requiring massage, such as the face or arm. In this embodiment, the first massage part 112 is equipped with a vibration motor 113, which can be single or multiple, stimulating the massaged area through high-frequency vibration.

[0034] In this application, the housing 100 also includes a second massage portion 118, which extends obliquely from the middle of the main body 110 toward the side where the first massage portion 112 is located, such that the second massage portion 118 and the main body 110 form an angle, preferably between 45° and 85°. The second massage portion 118 and the first massage portion 112 are offset by a certain distance both laterally and longitudinally, so that they can act on two different parts of the human body simultaneously, such as the face and neck respectively.

[0035] like Figure 2-3As shown, the ball bearing section 120 is installed on the second massage section 118, and includes an annular guide and a plurality of balls 122 arranged circumferentially along the guide.

[0036] In the illustrated embodiment, the second massage portion 118 is in the shape of a short rod and has an annular groove 119 extending to the free end of the second massage portion 118 (i.e., the end away from the main body portion 110). Specifically, the second massage portion 118 forms a first sidewall 119a and a second sidewall 119b on opposite sides of the annular groove 119. Ball bearings 122 are embedded in the annular groove 119, with most of the ball bearings 122 partially extending out of the annular groove 119 to massage the body parts that are in contact with the second massage portion 118, such as the face and neck.

[0037] Preferably, the surface of the ball bearing 122 is smooth and its shape is regular; it can be a sphere, ellipsoid, cylinder, etc. When the ball bearing 122 slides on the second massage part 118, it sequentially acts on the massaged areas of the human body, producing a massage effect. The ball bearing 122 can also be any other irregular shape; this application does not impose any limitations on this.

[0038] like Figure 3-4 As shown, in this embodiment, the guide member is a guide ring 123 in which several balls 122 are connected in series. The balls 122 are slidably connected to the guide ring 123, and under the action of the drive assembly 200, the balls 122 slide along the guide ring 123. Specifically, each ball 122 is provided with a through hole, and the guide ring 123 passes through the through holes of several balls 122 in sequence to connect all the balls 122. Preferably, the size of the through hole is slightly larger than the cross-sectional size of the guide ring 123, so that the balls 122 can slide and rotate freely relative to the guide ring 123.

[0039] like Figure 2 and 4 As shown, the first sidewall 119a of the second massage part 118 forms an annular first ball bearing seat 124a, and the second sidewall 119b forms an annular second ball bearing seat 124b. A plurality of balls 122 are sandwiched between the first ball bearing seat 124a and the second ball bearing seat 124b. An annular groove 119 is formed between the ball bearing seats 124a and 124b. Preferably, the groove wall of the annular groove 119, that is, the sidewalls of the ball bearing seats 124a and 124b facing each other, are all concave surfaces. This adapts to the shape of the balls 122 while making the distance between the inner and outer edges of the two ball bearing seats 124a and 124b smaller than the distance at other positions. This allows the balls 122 to be held between them without automatically detaching. At the same time, the balls 122 can also protrude from the outer edge of the ball bearing seats 124a and 124b to act on the massaged part of the human body.

[0040] In the illustrated embodiment, the guide ring 123 connects the ball bearings 122 in series, facilitating the assembly of the ball bearings 122 and guiding their sliding within the annular groove 119. In some embodiments, the guide ring 123 can be omitted, and several ball bearings 122 can be directly arranged sequentially in the annular groove 119. In this case, the annular groove 119 can be considered as a guide element. By setting the dimensions of the annular groove 119, the ball bearings 122 can slide within the annular groove 119 without detaching from it. The guide element, whether a guide ring or an annular groove, allows each ball bearing 122 to sequentially act on the massaged area of ​​the human body, producing continuous massage stimulation.

[0041] In the illustrated embodiment, the central axis of the ball bearing portion 120 is substantially perpendicular to the direction in which the second massage portion 118 extends obliquely from the main body portion 110. When the ball bearing portion 120 is driven, each ball bearing 122 moves sequentially toward the free end of the second massage portion 118.

[0042] In other embodiments, the ball bearing portion 120 may also be fitted onto the outer peripheral surface of the second massage portion 118, such that its central axis is substantially consistent with the direction in which the second massage portion 118 extends obliquely from the main body portion 110.

[0043] In other embodiments, the ball bearing 120 may also be provided on the first massage portion 112; or, the ball bearing 120 may be provided on both the first massage portion 112 and the second massage portion 118.

[0044] like Figure 4 As shown, the drive mechanism 200 includes a drive motor 210 and a transmission assembly 220. The transmission assembly 220 is connected between the drive motor 210 and the balls 122 of the ball bearing section 120, and is used to transmit the torque generated by the drive motor 210 to the balls 122 of the ball bearing section 120 to drive the balls 122 to rotate.

[0045] A reduction gear set 230 is also included between the drive motor 210 and the transmission assembly 220. The reduction gear set 230 not only enables the reduction transmission of power between the drive motor 210 and the transmission assembly 220, but also allows the direction of power transmission to be adjusted as needed.

[0046] like Figure 3-4As shown, specifically, the gear set 230 includes multiple gears, such as a first gear 231, a second gear 232, a third gear 233, a fourth gear 234, a fifth gear 235, and a sixth gear 236 that mesh with each other. The first gear 231 is connected to the output shaft 211 of the drive motor 210, and the transmission assembly 220 is connected to the sixth gear 236. At least two of the gears, such as the first gear 231 and the second gear 232, are helical gears, while the other gears can be spur gears. Through the engagement of the two helical gears 231 and 232, the rotation axis of the transmission assembly 220 is made perpendicular to the output shaft 211 of the drive motor 210, achieving a 90-degree change of direction.

[0047] It should be understood that the number, structure, size, etc. of the gears in the gear set 230 can be adjusted as needed, and are not limited to the illustrated embodiments.

[0048] like Figure 4-5 As shown, the transmission assembly 220 includes a driving wheel 222, a belt 224, and a driven wheel 226. In a specific embodiment, the driving wheel 222 includes a cylindrical first body 227a, on which a first circumferential groove 228a adapted to the size of the belt 224 is formed; similarly, the driven wheel 226 also includes a cylindrical second body 227b, on which a second circumferential groove 228b adapted to the size of the belt 224 is formed. The belt 224 is sleeved on the driving wheel 222 and the driven wheel 226 and embedded in the circumferential grooves 228a and 228b. The first body 227a of the driving wheel 222 is fixedly connected to the sixth gear 236, preferably coaxially arranged. When the driving wheel 222 rotates under the drive of the sixth gear 236, it drives the driven wheel 226 to rotate via the belt 224.

[0049] A plurality of first paddles 229a are provided on the outer peripheral surface of the first body 227a of the drive wheel 222. The first paddles 229a are preferably integrally formed from the outer peripheral surface of the first body 227a, and the plurality of first paddles 229a are evenly spaced along the circumference of the first body 227a. The free ends of some of the first paddles 229a extend into the space between two adjacent balls 122, and the rotation of the first paddles 229a drives the balls 122 to slide along the guide.

[0050] The bodies 227a and 227b of the driving wheel 222 and the driven wheel 226 are inserted into the first ball bearing seat 124a and the second ball bearing seat 124b, respectively, and are spaced apart. The first body 227a of the driving wheel 222 has a first shaft 261 at its center, with its two ends extending outward and respectively connected to the first side wall 119a and the second side wall 119b of the second massage part 118, thus pivotally connecting the driving wheel 222 to the second massage part 118. Similarly, the second body 227b of the driven wheel 226 has a second shaft 262 at its center, with its two ends extending outward and respectively connected to the first side wall 119a and the second side wall 119b of the second massage part 118, thus pivotally connecting the driven wheel 226 to the second massage part 118.

[0051] When the driving wheel 222 and the driven wheel 226 rotate, the first paddle 229a inserted between the adjacent balls generates a thrust on the ball 122, thereby enabling the ball 122 to slide along the guide.

[0052] Preferably, a plurality of second paddles 229b are provided on the outer peripheral surface of the second body 227b of the driven wheel 226. The second paddles 229b are preferably integrally formed from the outer peripheral surface of the second body 227b, and the plurality of second paddles 229b are evenly spaced along the circumference of the second body 227b. The free ends of some of the second paddles 229b extend into the space between two adjacent balls 122, which can further push the balls 122 to slide along the guide member.

[0053] The first and second paddles 229a and 229b are preferably wedge-shaped, with their thickness gradually decreasing outward from the bodies 227a and 227b. The number of the first and second paddles 229a and 229b can be six, eight, or similar, specifically adapted to the size of the ball bearing 122. Preferably, the first and second paddles 229a and 229b are the same size and equal in number.

[0054] In this embodiment, the second gear 232 and the third gear 233 are coaxially arranged, and preferably they are an integral structure; the drive wheel 222 and the sixth gear 236 are coaxially arranged, and preferably they are an integral structure, thereby simplifying the structure and assembly process. Of course, the above structure can also be formed separately and then assembled with the corresponding components.

[0055] In some embodiments, the drive wheel 222 can drive the ball bearing 120 to rotate independently. In this case, the ball bearing 120 can be annular and directly fitted onto the drive wheel 222, omitting the belt 224 and the driven wheel 226.

[0056] In some embodiments, there may be other transmission methods between the driving wheel 222 and the driven wheel 226, such as sprocket drive.

[0057] The implementation of the transmission component 220 is not limited to the above embodiments. It can be any form, such as a worm gear, a gear set, or a combination of multiple transmission structures, as long as it can drive the ball part 120 to move along the guide member. It is not limited to the belt pulley transmission shown in the figure.

[0058] like Figure 3 As shown, according to one embodiment of this application, the housing 100 includes a rigid inner shell 130 and a flexible soft shell 140 sleeved outside the rigid inner shell 130. The rigid inner shell 130 can be a rigid material such as plastic or alloy, and has a certain supporting function. The drive mechanism 200 is disposed inside the rigid inner shell 130. The flexible soft shell 140 can be a flexible and skin-friendly material such as silicone or rubber. The flexible soft shell 140 is the direct surface layer of massage contact, providing a soft touch and cushioning effect when applied to the human body, which can improve the comfort of massage and enhance the user experience.

[0059] like Figure 1 As shown, in some embodiments of this application, the balls 122 of the ball bearing portion 120 can be made of a rigid material, and each ball 122 is covered with a flexible material. When the balls 122 move, some of the balls 122 protrude from the annular groove 119 and directly act on the area of ​​the body being massaged. For example... Figure 6-7 As shown, in some other embodiments of this application, the balls 122 of the ball bearing portion 120 are made of a rigid material. In this case, the outer surface of the balls 122 is not covered with a flexible material, and some balls 122 protrude from the annular groove 119 and are enclosed within the flexible shell 140. When the balls 122 move, they move relative to the flexible shell 140, and some balls 122 act on the massaged area of ​​the human body through the flexible shell 140. This ensures that the rigid balls 122 can produce the required stimulation effect when rotating, while providing a soft touch and appropriate cushioning to the massaged area.

[0060] The massager of this application may also include a battery 310, a circuit board 320, and a button 330. The battery 310 is preferably a rechargeable battery, serving as the power source for the massager 10 and supplying power to the drive motor 210 and the vibration motor 113. The circuit board 320 electrically connects the battery 310, the drive motor 210, and the vibration motor 113 to form a control circuit, used to control the operation of the drive motor 210 and the vibration motor 113, such as controlling the rotational speed of the drive motor 210 and the vibration frequency of the vibration motor 113. The button 330 is connected to the circuit board 320, allowing the user to input commands via the button 330 to control the drive motor 210 and the vibration motor 113 to operate individually or simultaneously, thereby controlling the vibration of the first massage section 112 and the sliding of the ball bearings 112 of the second massage section 118. Preferably, the battery 310, circuit board 320, etc., are disposed in the handheld part 116, and the button 330 is disposed on the corresponding housing 100 of the handheld part 116.

[0061] The above embodiments are merely descriptions of preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
