[0037] In the description of the embodiments of the present application, it should be noted that the directions or positional relationships indicated by the terms "first direction", "second direction" and the like are based on the attached Figure 1 The directions or positional relationships shown in the figure, and the directions or positional relationships indicated by the terms "third direction" and the like are based on the attached Fig. 9 The orientation or positional relationship shown, these orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0038] The present application embodiment provides a beauty instrument, see Figures 1 to 9 The beauty instrument includes a transducer 20 and a multi-directional adjustment mechanism 10.

[0039] The beauty instrument described in the present application may be a home beauty instrument or a medical beauty instrument.

[0040] The beauty instrument can be an integrated type, that is, all the parts of the beauty instrument are assembled into an integral structure that can be held in hand. The beauty instrument can also be a split type, that is, the beauty instrument is provided with a probe and a main body, and the probe is connected to the main body through an external cable, and the user holds the probe to operate. For the split type beauty instrument, the transducer 20 and the multi-directional adjustment mechanism 10 are arranged on the probe.

[0041] Transducer 20 is a device that is capable of converting one form of energy into another form of energy.

[0042] For example, Figure 1 The beauty instrument shown is an ultrasonic beauty instrument, and the transducer 20 of the ultrasonic beauty instrument can convert electrical energy into ultrasonic energy, so as to perform physical therapy or beauty treatment on a person's body, face, etc. through ultrasonic energy.

[0043] It should be noted that the beauty instrument described in the present application is not limited to an ultrasonic beauty instrument, and the beauty instrument may also be any other beauty instrument provided with a transducer 20 .

[0044] See also Figures 1 to 9 The multi-directional adjustment mechanism 10 of the embodiment of the present application includes a transducer bracket 11, a first transmission assembly 12, a second transmission assembly 13 and a driving device 14.

[0045] The transducer holder 11 has a plurality of first teeth 11 a. The transducer 20 is disposed on the transducer holder 11 .

[0046] Figure 7 The first teeth 11a shown are directly formed on the transducer bracket 11. In other embodiments, the transducer bracket 11 may also be provided with a bracket body and a connecting member having a plurality of first teeth 11a, and the connecting member is installed on the bracket body. That is to say, the connecting member can be manufactured separately and then installed on the bracket body.

[0047] See also Figures 1 to 7 The first transmission assembly 12 includes a screw rod 121 and a screw rod support 122 threadedly connected to the screw rod 121 .

[0048] The first transmission assembly 12 is a transmission assembly that converts rotational motion into linear reciprocating motion. Specifically, the screw rod 121 is threadedly connected to the screw rod support 122, so that the screw rod support 122 can reciprocate along the screw rod 121 during the rotation of the screw rod 121.

[0049] Figure 7 The screw support 122 shown is provided with a frame body 1221 and a connecting nut 1222 , and the connecting nut 1222 is threadedly connected to the screw 121 , that is, the screw support 122 is threadedly connected to the screw 121 through the connecting nut 1222 .

[0050] In some other embodiments, the connecting nut 1222 may not be provided. For example, the frame body 1221 may be provided with a threaded hole, and the frame body 1221 is threadedly connected to the screw rod 121 through the threaded hole.

[0051] The transducer support 11 is movably arranged on the screw support 122, that is, the transducer support 11 can move on the screw support 122. The screw 121 rotates so that the screw support 122 drives the transducer support 11 to reciprocate linearly along the first direction.

[0052] It should be noted that the linear reciprocating motion described in the present application refers to movement in one direction along a straight line, or movement in a direction opposite to the straight line. The linear reciprocating motion may be a periodic motion. For example, taking the transducer bracket 11 as an example, the transducer bracket 11 may move back and forth in a first direction within the same time interval. The linear reciprocating motion may also be a non-periodic motion. For example, the transducer bracket 11 may move in only one direction within a period of time, and not in the opposite direction.

[0053] The first transmission assembly 12 may only include the screw rod 121 , that is, the first transmission assembly 12 may only realize transmission through the screw rod 121 .

[0054] The first transmission assembly 12 may also be provided with other transmission parts in addition to the screw rod 121 , that is, the first transmission assembly 12 may realize transmission through a combination of the screw rod 121 and other transmission parts.

[0055] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 The second transmission assembly 13 includes a meshing gear rod 131 having a plurality of second teeth 131a.

[0056] The second teeth 131a of the meshing gear rod 131 mesh with the first teeth 11a of the transducer holder 11, so that the meshing gear rod 131 drives the transducer holder 11 to reciprocate linearly along a second direction intersecting the first direction through rotation.

[0057] The second transmission assembly 13 may only have the meshing gear rod 131 , that is, the second transmission assembly 13 may only realize transmission by meshing the gear rod 131 .

[0058] The second transmission assembly 13 may also be provided with other transmission parts in addition to the meshing gear rod 131 , that is, the second transmission assembly 13 may realize transmission through the combination of the meshing gear rod 131 and other transmission parts.

[0059] Please continue reading Figure 1 , Figure 2 and Fig. 9 The meshing gear rod 131 and the screw rod 121 are arranged side by side along a third direction, and the third direction is perpendicular to the first direction and the second direction respectively.

[0060] The meshing gear rod 131 and the screw rod 121 are arranged side by side along the third direction, which means that on a projection plane perpendicular to the third direction, the projection of the meshing gear rod 131 and the projection of the screw rod 121 at least partially overlap, rather than being completely offset.

[0061] Figure 2 The transducer holder 11 and the screw rod 121 are shown to be located at opposite sides of the meshing gear rod 131 along the third direction. In other embodiments, the transducer holder 11 and the screw rod 121 may also be located at the same side of the meshing gear rod 131 along the third direction.

[0062] The purpose of arranging the meshing gear rod 131 and the screw rod 121 side by side along the third direction is to save the installation space occupied by the meshing gear rod 131 and the screw rod 121 in the second direction, so that the overall structure of the multi-directional adjustment mechanism 10 can be relatively compact.

[0063] Please continue reading Figures 1 to 5 The driving device 14 is respectively connected to the screw rod 121 and the meshing gear rod 131 to drive the screw rod 121 and the meshing gear rod 131 to rotate.

[0064] That is, the driving device 14 drives the screw 121 to rotate, so that the screw support 122 drives the transducer support 11 to reciprocate linearly in the first direction, and the driving device 14 drives the meshing gear rod 131 to rotate, so that the meshing gear rod 131 drives the transducer support 11 to reciprocate linearly in the second direction. It is equivalent to that under the drive of the driving device 14, the first transmission assembly 12 and the second transmission assembly 13 can respectively drive the transducer support 11 to reciprocate linearly in two different directions, so that the transducer 20 arranged on the transducer support 11 can also reciprocate linearly in two different directions under the drive of the transducer support 11.

[0065] The first direction may be perpendicular to the second direction, or may be oblique to the second direction. However, in order to facilitate the control of the movement direction of the transducer support 11, it is preferred that the first direction is perpendicular to the second direction.

[0066] The first direction and the second direction may be two translation directions of the transducer holder 11. The translation direction refers to the direction in which the transducer holder 11 can drive the transducer 20 to translate on the surface of the human skin. That is, when the first direction and the second direction are the two translation directions of the transducer holder 11, the transducer holder 11 can drive the transducer 20 to translate along two different directions on the surface of the human skin, for example, Figure 1The first direction and the second direction of the transducer support 11 shown are two translation directions.

[0067] In other embodiments, one of the first direction and the second direction may be the translation direction of the transducer holder 11, and the other may be the telescopic direction of the transducer holder 11, that is, if the first direction is the translation direction, the second direction is the telescopic direction, and if the second direction is the translation direction, the first direction is the telescopic direction. The telescopic direction refers to the direction in which the transducer holder 11 can be extended and retracted, that is, the transducer holder 11 can drive the transducer 20 to move in a direction close to the human skin by extending, and the transducer holder 11 can drive the transducer 20 to move in a direction away from the human skin by retracting.

[0068] According to different control requirements, the driving device 14 can only drive the screw rod 121 to rotate, but not drive the meshing gear rod 131 to rotate, that is, the transducer 20 is driven by the transducer bracket 11 to reciprocate linearly only in the first direction, but not in the second direction; the driving device 14 can also only drive the meshing gear rod 131 to rotate, but not drive the screw rod 121 to rotate, that is, the transducer 20 is driven by the transducer bracket 11 to reciprocate linearly only in the second direction, but not in the first direction; the driving device 14 can also drive both the screw rod 121 and the meshing gear rod 131 to rotate, that is, the transducer 20 can be driven by the transducer bracket 11. Can reciprocate linearly in the first direction and the second direction at the same time.

[0069] The multi-directional adjustment mechanism 10 of the embodiment of the present application can make the first transmission assembly 12, the second transmission assembly 13 and the transducer bracket 11, so that the first transmission assembly 12 and the second transmission assembly 13 can be driven by the driving device 14 to drive the transducer bracket 11 to reciprocate linearly in the first direction and the second direction respectively, so that the transducer 20 arranged on the transducer bracket 11 can reciprocate linearly in two different directions to achieve multi-row energy output, thereby improving the operating efficiency of the beauty instrument. The meshing gear rod 131 and the screw rod 121 are arranged side by side along the third direction, which can save the installation space occupied by the meshing gear rod 131 and the screw rod 121 in the second direction, so that the overall structure of the multi-directional adjustment mechanism 10 can be relatively compact, and the overall structure of the beauty instrument can be relatively compact, which is conducive to the miniaturization of the beauty instrument. In other words, the multi-directional adjustment mechanism 10 of the embodiment of the present application can not only improve the operating efficiency of the beauty instrument, but also make the overall structure of the beauty instrument relatively compact.

[0070] In one embodiment, please refer to Figures 1 to 5The driving device 14 can be provided with a first driving motor 141 having a first driving shaft 141a and a second driving motor 142 having a second driving shaft 142a. The first driving motor 141 is drivingly connected to the screw rod 121 via the first driving shaft 141a, and the second driving motor 142 is drivingly connected to the meshing gear rod 131 via the second driving shaft 142a. That is to say, two driving motors can be provided to respectively drive the screw rod 121 and the meshing gear rod 131 to rotate.

[0071] See also Figures 1 to 5 , Fig. 9 The first drive motor 141 and the second drive motor 142 can be arranged side by side along the second direction, and the setting position of the first drive shaft 141a and the setting position of the second drive shaft 142a are respectively staggered with the screw rod 121 and the meshing gear rod 131 in the third direction.

[0072] That is to say, on the projection plane perpendicular to the second direction, the projection of the first drive motor 141 and the projection of the second drive motor 142 at least partially overlap, but are not completely staggered. At the same time, on the projection plane perpendicular to the third direction, the projection of the first drive shaft 141a does not overlap with the projection of the screw rod 121, that is, the projection of the first drive shaft 141a and the projection of the screw rod 121 are completely staggered, and the projection of the first drive shaft 141a and the projection of the meshing gear rod 131 do not overlap, that is, the projection of the first drive shaft 141a and the projection of the meshing gear rod 131 are completely staggered. Similarly, on the projection plane perpendicular to the third direction, the projection of the second drive shaft 142a does not overlap with the projection of the screw rod 121, that is, the projection of the second drive shaft 142a and the projection of the screw rod 121 are completely staggered, and the projection of the second drive shaft 142a and the projection of the meshing gear rod 131 do not overlap, that is, the projection of the second drive shaft 142a and the projection of the meshing gear rod 131 are completely staggered.

[0073] It can be understood that after the setting position of the first drive shaft 141a and the setting position of the second drive shaft 142a are respectively staggered with the screw rod 121 and the meshing gear rod 131 in the third direction, the first transmission component 12 can be transmitted by a combination of the screw rod 121 and other transmission parts (such as transmission gears, pulleys, etc.), and the second transmission component 13 can be transmitted by a combination of the meshing gear rod 131 and other transmission parts (such as transmission gears, pulleys, etc.).

[0074] By staggering the setting position of the first drive shaft 141a and the setting position of the second drive shaft 142a with respect to the screw rod 121 and the meshing gear rod 131 in the third direction, the spacing between the screw rod 121 and the meshing gear rod 131 in the third direction can be adjusted. For example, the screw rod 121 and the meshing gear rod 131 can be as close as possible in the third direction, which is equivalent to that the spacing between the screw rod 121 and the meshing gear rod 131 in the third direction can be configured according to the minimum spacing, thereby reducing the installation space occupied by the screw rod 121 and the meshing gear rod 131 in the third direction, thereby making the overall structure of the multi-directional adjustment mechanism 10 more compact.

[0075] In one embodiment, please refer to Figure 5 , Figure 6 , Figure 8 and Fig. 9 The first transmission assembly 12 can be provided with a first transmission gear 123 and a screw gear 124. The screw gear 124 is sleeved on the screw 121 and meshes with the first transmission gear 123. The first driving motor 141 drives the first transmission gear 123 to rotate, so that the screw gear 124 drives the screw 121 to rotate.

[0076] That is to say, the first drive motor 141 can drive the first transmission gear 123 to rotate, so that the first transmission gear 123 drives the screw gear 124 to rotate, which is equivalent to the first drive motor 141 driving the first transmission gear 123 to rotate to indirectly drive the screw gear 124 to rotate, thereby allowing the screw 121 to rotate together with the screw gear 124.

[0077] Please continue reading Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 The driving device 14 may further include a first output gear 143 , which is sleeved on the first driving shaft 141 a and meshes with the first transmission gear 123 .

[0078] That is, the first output gear 143 may rotate together with the first driving shaft 141 a of the first driving motor 141 to drive the first transmission gear 123 to rotate.

[0079] The first output gear 143 is provided to facilitate the first drive motor 141 to drive the first transmission gear 123 to rotate, and to facilitate the arrangement of the lead screw 121 and the first drive motor 141 in a limited space of the beauty instrument.

[0080] In other embodiments, the driving device 14 may not be provided with the first output gear 143. For example, the first transmission gear 123 may be mounted on the first driving shaft 141a of the first driving motor 141, which means that the first transmission gear 123 can rotate directly driven by the first driving shaft 141a.

[0081] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 The second transmission assembly 13 may be provided with a second transmission gear 132, a mounting rod 133 and a third transmission gear 134. The meshing gear rod 131 and the third transmission gear 134 are both sleeved on the mounting rod 133, and the third transmission gear 134 is meshed with the second transmission gear 132. The second driving motor 142 drives the second transmission gear 132 to rotate, thereby driving the meshing gear rod 131 to rotate.

[0082] That is to say, the second transmission gear 132 rotates under the drive of the second drive motor 142 to drive the third transmission gear 134 to rotate. At the same time, since the meshing gear rod 131 and the third transmission gear 134 are both mounted on the mounting rod 133, during the rotation of the third transmission gear 134, the meshing gear rod 131 will also rotate with the third transmission gear 134.

[0083] In some other embodiments, see Fig.10 The second transmission gear 132 may also be meshed with the meshing gear rod 131 , and the second driving motor 142 drives the second transmission gear 132 to rotate, thereby driving the meshing gear rod 131 to rotate.

[0084] Please continue reading Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 The driving device 14 may further include a second output gear 144 , which is sleeved on the second driving shaft 142 a and meshes with the second transmission gear 132 .

[0085] That is, the second output gear 144 can rotate together with the second driving shaft 142 a of the second driving motor 142 to drive the second transmission gear 132 to rotate.

[0086] The second output gear 144 is provided to facilitate the second drive motor 142 to drive the second transmission gear 132 to rotate, and to facilitate the arrangement of the meshing gear rod 131 and the second drive motor 142 in a limited space of the beauty instrument.

[0087] In other embodiments, the second transmission component 13 may not be provided with the second output gear 144. For example, the second transmission gear 132 may be mounted on the second drive shaft 142a of the second drive motor 142, which is equivalent to the second transmission gear 132 being able to rotate directly driven by the second drive shaft 142a. Alternatively, the second transmission component 13 may also be provided with other transmission mechanisms, and the second drive motor 142 drives the second transmission gear 132 to rotate via other transmission mechanisms.

[0088] In other embodiments, the second transmission assembly 13 may not be provided with the second transmission gear 132. For example, for the second transmission assembly 13 provided with the third transmission gear 134, the third transmission gear 134 can be sleeved on the second drive shaft 142a of the second drive motor 142. For the second transmission assembly 13 not provided with the third transmission gear 134, the meshing gear rod 131 can be sleeved on the second drive shaft 142a of the second drive motor 142.

[0089] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Fig. 9 , the second teeth 131a can extend along the first direction and guide and cooperate with the first teeth 11a. That is to say, the meshing gear rod 131 has a relatively long length dimension in the first direction. When the transducer holder 11 linearly reciprocates along the first direction, the transducer holder 11 actually also linearly reciprocates along the extending direction of the second teeth 131a on the meshing gear rod 131. At this time, the second teeth 131a guide the first teeth 11a, so that the transducer holder 11 can be better guided to linearly reciprocate along the first direction.

[0090] In other embodiments, the driving device 14 can also drive the first transmission component 12 and the second transmission component 13 respectively by setting a driving motor. For example, the driving motor can have two driving shafts, one driving shaft is connected to the screw rod 121, and the other driving shaft is connected to the meshing gear rod 131.

[0091] In one embodiment, the transducer holder 11 can be slidably connected to the screw holder 122, that is, the transducer holder 11 can slide on the screw holder 122 along the second direction, thereby providing a better guide for the linear reciprocating motion of the transducer holder 11 along the second direction.

[0092] The manner in which the transducer support 11 and the screw support 122 are slidably connected is not limited. For example, see Figure 3 , Figure 7 and Fig. 9The transducer bracket 11 may be provided with a first guide rod 1223 on the bracket body 1221 , and the first guide rod 1223 extends along the second direction, that is, the axis of the first guide rod 1223 is parallel to the second direction, and the transducer bracket 11 is slidably connected to the first guide rod 1223 .

[0093] In some other embodiments, the transducer bracket 11 may also be provided with a slide rail extending along the second direction on the bracket body 1221 , and the transducer bracket 11 is slidably connected to the slide rail.

[0094] In one embodiment, please refer to Figure 1 The beauty instrument may be provided with a guide member 40 extending along the first direction in the housing 30. Figure 1 The guide member 40 shown is a second guide rod. In other embodiments, the guide member 40 may also be a guide structure such as a guide rail.
