[0008] The upper end of the main body part one is externally provided with a rotating locking mechanism one, and the main body part two is provided with a rotating locking mechanism two which is shaped to match the rotating locking mechanism one; the rotating locking mechanism one is a sheet-shaped structure which is arranged perpendicularly to the axial direction of the main body part one, and the sheet-shaped structure is provided with at least two sheets which are evenly distributed horizontally; the edge of the sheet-shaped structure which is parallel to the outer surface of the main body part one is provided with a groove;

[0009] The rotating locking mechanism two is provided with a magnetic push locking device which is provided with a locking piece, two magnetic push devices, two limiting pieces and two fixing pieces; the two magnetic push devices are arranged perpendicularly to the axial direction of the working head and are each provided with a magnetic component one and a magnetic component two, the opposite ends of the magnetic component one and two have the same magnetic pole, the magnetic component one is arranged close to the inner side, the two ends of the locking piece are fixed on one magnetic component one respectively, and the locking piece is applied with a pushing force through the repulsion between the magnetic components with the same magnetic pole; the magnetic component one and the magnetic component two are provided with a gap therebetween to facilitate the movement of the locking piece. The limiting pieces are arranged on the two sides of the magnetic push device to prevent the magnetic component one and the magnetic component two of each magnetic push device from being laterally dislocated due to the repulsion between the magnetic poles. The locking piece is a rod-shaped piece which is arranged perpendicularly to the sheet-shaped structure of the working head, and the locking piece is movable along the axial direction of the limiting piece; the diameter of the locking piece is the same as the size of the groove of the sheet-shaped structure.

[0010] Preferably, the groove is provided with a smooth transition arc at the joint with the edge of the sheet-shaped structure, and the two arcs have different curvatures; the curvature of the arc along the horizontal rotation direction of the working head body is smaller than the curvature of the other arc.

[0011] Since the curvature of the arc along the horizontal rotation direction of the working head body is smaller than the curvature of the other arc, on the one hand, the locking piece is facilitated to be clamped into the groove when the working head body is horizontally rotated, and on the other hand, the locking piece is prevented from passing over the groove.

[0012] Preferably, the sheet-shaped structure is integrally formed with the main body part one.

[0013] Preferably, the cross-sectional area of the main body part one is larger than that of the docking mechanism one, the upper part of the main body part one is a planar structure, the center of the planar structure is connected with the bottom of the docking mechanism one, and the central axis of the planar structure is coincident with the central axis of the docking mechanism one.

[0014] Preferably, the main body part one is a massage head, the edge of the upper end of the massage head is provided with an inwardly-retracted step three, a sealing ring three is sleeved on the step three, and the sheet-shaped structure is arranged on the vertical wall of the step three and below the sealing ring.

The locking member works with the magnetic push device to realize the change of the working position of the locking member.

[0018] After the working head body is inserted into the hand tool body and rotated horizontally, the locking element remains in the groove, thereby limiting the horizontal rotation of the working head body; at the same time, the receiving groove limits the vertical direction of the working head body. Thus, the working head is securely installed through the combined action of the locking element and the receiving groove.

[0035] The present application will now be further described with reference to the accompanying drawings and specific embodiments.

[0036] Please see Figure 1 and Figure 2 A beauty hand tool with good working head rotation magnetic push locking performance, comprising a working head body and a beauty hand tool body.

[0037] The working head body has a docking mechanism 14 located at the top and a main body part 1 located at the bottom and integrally formed with the docking mechanism 1.

[0038] The lower end of the beauty hand tool body has a second docking mechanism 19 that is adapted to the shape of the first docking mechanism and a second main body part 18 that is adapted to the shape of the first main body part.

[0039] The cross-sectional area of ​​the main body part 1 is larger than the cross-sectional area of ​​the docking mechanism 14. The upper part of the main body part 1 is a planar structure. The center of the planar structure is connected to the bottom of the docking mechanism 1, and the central axis of the planar structure coincides with the central axis of the docking mechanism 1.

[0040] Please see Figure 5 and Figure 6 The end edge of docking mechanism one has an inwardly recessed step two T2, and a sealing ring two Q2 is installed on step two T2. The sealing ring two Q2 is used for sealing when docking mechanism one is connected to docking mechanism two 19.

[0041] A rotary locking mechanism 1 is provided on the upper exterior of the main body part 1, and a rotary locking mechanism 2 is provided on the main body part 2, which is adapted to the shape of the rotary locking mechanism 1; the rotary locking mechanism 1 is a plate-like structure 15 arranged perpendicular to the axial direction of the main body part 1 (see [link]). Figure 5 and Figure 6 The sheet-like structures are at least two and are evenly distributed horizontally; the edges of the sheet-like structures parallel to an outer surface of the main body have grooves 16.

[0042] The groove and the edge of the sheet structure have a smooth transition arc, and the curvature of the two arcs is different; the structure of each sheet structure is the same.

[0043] Preferably, the arc of the groove 16 along the horizontal rotation direction of the working head body is smaller than the arc of the other side.

[0044] When installing the working head, the first rotating locking mechanism is inserted into the second rotating locking mechanism, and then the working head body is fixedly installed on the beauty tool body by horizontal rotation (see [link]). Figure 4 ).

[0045] like Figure 3 As shown, the rotary locking mechanism two has a magnetic push locking device.

[0046] like Figure 3 As shown, the magnetic push locking device has a locking member 15-2, two magnetic push devices, two limiting members 15-6, and a fixing member 15-4 for mounting the magnetic push devices. The two magnetic push devices are respectively arranged perpendicular to the axial direction of the working head and each has a magnetic component 15-51 and a magnetic component 15-52. The magnetic poles at opposite ends of magnetic components 1 and 2 are the same. Magnetic component 1 is located close to the inner side of the handpiece body. The two ends of the locking member are respectively fixed to one of magnetic components 1, and a pushing force is applied to the locking member by the repulsive force between the same magnetic poles. There is a gap between magnetic components 1 and 2 to facilitate the movement of the locking member. The limiting members are located on both sides of the magnetic push devices to prevent lateral misalignment of magnetic components 1 and 2 due to the repulsive force between their magnetic poles. The locking member is a rod-shaped piece with a plate-like structure perpendicular to the working head, and the locking member can move along the axial direction of the limiting members. The diameter of the locking member is the same as the size of the groove in the plate-like structure.

[0047] The fasteners 15-4 are located at the two outer ends of each magnetic push device. The main body part 2 has mounting holes (not shown) corresponding to the positions of the fasteners for mounting the fasteners 15-4, thereby fixing the magnetic push locking device.

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, the second main body has a through groove 15-1 corresponding to the sheet-like structure, so that the first main body can be inserted into the interior of the second main body.

[0049] like Figure 4 As shown, a receiving groove 15-3 is provided at the top of the through groove in the direction of horizontal rotation. The function of the receiving groove is to adapt to the plate structure after the working head is inserted into the hand tool and rotated horizontally. A locking member 15-2 that is adapted to the size of the groove is provided on the side of the receiving groove near the rotating locking mechanism and corresponding to the groove of the plate structure. The locking member works with the elastic member to realize the change of its working position.

[0050] like Figure 5As shown, since the arc of the groove along the horizontal rotation direction of the working head body is smaller than the arc of the other side, it is convenient for the locking part to be inserted into the groove when the working head body rotates horizontally, and it can also prevent the locking part from going over the groove.

[0051] The working head can be quickly installed and removed by using a magnetic locking device in conjunction with a groove.

[0052] After the working head body is inserted into the hand tool body and rotated horizontally, the locking element remains in the groove, thereby limiting the horizontal rotation of the working head body; at the same time, the receiving groove limits the vertical direction of the working head body. Thus, the working head is securely installed through the combined action of the locking element and the receiving groove.

[0053] Preferably, the main body part one is a massage head 11. The upper end edge of the massage head has an inwardly recessed step three T3, and a sealing ring three Q3 is provided on the step three; the massage head is connected to the main body part two 18. A sheet-like structure is provided on the vertical wall of the step three and located below the sealing ring.

[0054] Alternatively, preferably, the main body part one consists of a massage head 11 located at the lower part and a structural member 12 located at the upper part of the massage head. The structural member 12 is connected to the main body part two 18. The upper end surface of the structural member 12 is a planar structure of the upper part of the main body part one. The center of the structural member is connected to the bottom of the docking mechanism one, and the central axis of the planar structure coincides with the central axis of the docking mechanism one. The edge of the upper end of the structural member 12 has an inwardly recessed step three T3. A sealing ring three Q3 is provided on the step three T3. A sheet-like structure is provided on the vertical wall of the step three and located below the sealing ring. The sealing ring three Q3 is used for sealing when the structural member 12 is connected to the main body part two 18. Figure 5 and Figure 6 As shown, the working head body also has a chip contact 1-1, an assembly screw 3, and an RF contact 5, which are respectively mounted on the structural component 12.

[0055] The chip is embedded inside the structural component 12, and the lower end of the chip contact 1-1 is connected to the chip. The assembly screw 3 is set on the step surface of step three T3 for assembly connection between the structural component 12 and the massage head 11.

[0056] Preferably, the docking mechanism is hollow inside to form a vacuum channel 9, and the main body is also hollow inside to form a vacuum channel 13, thereby forming a vacuum tube 1 inside the working head body, which is suitable for beauty hand tools and beauty instruments with vacuum function (i.e. negative pressure function).

[0057] Preferably, a second vacuum tube (not shown) is provided in the middle of the handpiece body and is sealed and connected to the first vacuum tube.

[0058] This application also provides a beauty device using the beauty hand tool.

[0059] This application provides a rotating locking mechanism 1 on the upper exterior of the main body of the working head and a corresponding rotating locking mechanism 2 with a magnetic locking device in the main body 2 inside the handpiece body. This enables the working head to be securely installed, quickly disassembled, and replaced on the beauty handpiece body, thereby not only improving customer satisfaction with the beauty device experience but also preventing safety accidents such as electric shock caused by instability or falling of the working head.
