Description

Technical Field

[0001] This application belongs to the field of massage and beauty technology, specifically providing a beauty hand tool and beauty instrument with good working head semi-thread locking performance. Background Technology

[0002] Chinese patent applications with application numbers CN202410397872X and CN2024206739904 disclose a “radio frequency therapy instrument working head and radio frequency instrument handpiece”, which is characterized by the ability to quickly change the working head of the radio frequency beauty handpiece.

[0003] The working head has a problem of not being securely fixed during actual use. That is, the working head may shift or even fall off during operation, which not only affects the customer's experience, but also poses a safety hazard because the massage handpiece contains current and high-frequency radio frequency.

[0004] Therefore, achieving both secure mounting of the working head on the massage handpiece and rapid replacement of the working head is an issue that needs improvement.

[0005] The information disclosed above, especially the technical problems, represents the inventor's creative discoveries based on their own knowledge and work experience, and after in-depth thinking and comprehensive summarization. It is not obvious. Its purpose is solely to facilitate understanding of the technical problems, solutions, and effects of this application by those skilled in the art, and should not be construed as an implication or admission in any form that the information is already publicly known to those skilled in the art. Summary of the Invention

[0006] To address the aforementioned issues, this application provides a beauty hand tool with excellent semi-threaded locking performance in its working head. The working head body has a rotating locking mechanism 1 on the outside of the main body part 1, and a rotating locking mechanism 2 with a semi-threaded locking structure is provided in the main body part 2 inside the lower end of the hand tool body. This allows for secure installation and quick disassembly of the beauty hand tool, thereby improving customer satisfaction, preventing safety accidents such as electric shock caused by working head instability or falling, and facilitating quick replacement of the working head.

[0007] The aforementioned beauty hand tool with good semi-threaded locking performance has a working head body and a beauty hand tool body. The working head body has a docking mechanism at the top and a main body part at the bottom that is integrally formed with the docking mechanism. A rotary locking mechanism is provided on the outside of the main body part.

[0008] The cross-sectional area of ​​the main body is larger than that of the docking mechanism. The upper part of the main body is a planar structure, the center of which is connected to the bottom of the docking mechanism, and the central axis of the planar structure coincides with the central axis of the docking mechanism.

[0009] The rotary locking mechanism is a sheet-like structure arranged perpendicular to the axial direction of the main body, that is, the sheet-like structure is horizontally arranged; there are at least two sheet-like structures arranged horizontally and evenly, and the sheet-like structures are integrally formed with the main body; each sheet-like structure has the same structure.

[0010] The beauty hand tool body has a docking mechanism 2 adapted to the docking mechanism 1 and a main body 2 adapted to the main body part 1; the main body part 2 is provided with a rotating locking mechanism 2 corresponding to the rotating locking mechanism 1; when the working head body is installed, the rotating locking mechanism 1 is inserted into the interior of the rotating locking mechanism 2, and then the working head body is fixedly installed on the beauty hand tool body by horizontal rotation.

[0011] The working head body is detachably connected through the cooperation of main body part one and main body part two.

[0012] The second rotary locking mechanism features a semi-threaded locking structure and a slot adapted to the plate-like structure for easy insertion into the hand tool. The semi-threaded locking structure includes a limiting member, an elastic semi-threaded member, and a stop member. The stop member is located at the tail end of the elastic semi-threaded member, and the head end of the elastic semi-threaded member is located at the slot. The elastic semi-threaded member is positioned above the limiting member, and a receiving groove is formed between the elastic semi-threaded member and the limiting member, allowing the plate-like structure of the working head to rotate horizontally, and limiting the vertical movement of the plate-like structure. The elastic semi-threaded member is arranged at an angle, with the angle causing the receiving groove between the elastic semi-threaded member and the limiting member to gradually decrease, thereby gradually increasing the pressure exerted on the plate-like structure by the elastic semi-threaded member when the working head rotates.

[0013] Preferably, the material of the elastic semi-threaded part is acrylic.

[0014] Preferably, the elastic semi-threaded part and the rotary locking mechanism are integrally formed.

[0015] When the working head rotates, the plate-like structure stops rotating after encountering the stop.

[0016] In use, after the working head is inserted into the hand tool and rotated horizontally, the plate-like structure remains in the receiving groove. A stop element limits the horizontal rotation of the working head, while the working head is fixed in position by the friction and pressure between the plate-like structure and the elastic semi-threaded component. Simultaneously, the receiving groove limits the vertical movement of the working head. After the working head is removed, the elastic semi-threaded component returns to its original position. Thus, the combined action of the stop element and the receiving groove ensures secure installation of the working head, as well as quick installation and removal.

[0017] Preferably, the docking mechanism 1 has a hollow interior forming a vacuum channel 1, and the main body 1 also has a hollow interior forming a vacuum channel 2, thereby forming a vacuum channel 1 inside the working head body, which is suitable for beauty hand tools and beauty instruments with vacuum function (i.e. negative pressure function).

[0018] Preferably, the handpiece body has a second vacuum channel in the middle that is sealed and connected to the first vacuum channel.

[0019] This application also provides a beauty device using the beauty hand tool.

[0020] This application provides a rotary locking mechanism 1 on the outside of the main body of the working head, and a rotary locking mechanism 2 with a semi-threaded locking structure that is adapted to the rotary locking mechanism 1 is provided inside the lower end of the beauty handpiece. This enables the working head to be securely installed, quickly disassembled and replaced on the beauty handpiece, 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 of the beauty device handpiece.

[0032] The present application will now be further described with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figure 1 and Figure 4 A beauty hand tool with good semi-threaded locking performance of the working head, comprising a working head body and a beauty hand tool body, wherein the working head body has a docking mechanism 14 located at the upper part and a main body part 1 located at the lower part and integrally formed with the docking mechanism 1, and a rotary locking mechanism 1 is provided on the outside of the main body part 1.

[0034] Please see Figure 4 The cross-sectional area of ​​the main body is larger than that of the docking mechanism. The upper part of the main body is a planar structure. The center of the planar structure is connected to the bottom of the docking mechanism, and the central axis of the planar structure coincides with the central axis of the docking mechanism.

[0035] Please see Figure 4 and Figure 5 The rotary locking mechanism is a sheet-like structure 15 arranged perpendicular to the axial direction of the main body. There are at least two sheet-like structures arranged horizontally and evenly, and each sheet-like structure is integrally formed with the main body; all sheet-like structures have the same structure.

[0036] Please see Figure 1 and Figure 2 The beauty hand tool body has a docking mechanism 2 19 adapted to the docking mechanism 1 and a main body part 2 18 adapted to the main body part 1; the main body part 2 is provided with a rotating locking mechanism 2 corresponding to the rotating locking mechanism 1. When the working head body is installed, the rotating locking mechanism 1 is inserted into the interior of the rotating locking mechanism 2, and then the working head body is fixedly installed on the beauty hand tool body by horizontal rotation.

[0037] The working head body is detachably connected to the main body of the beauty hand tool body via the first main body part and the second main body part.

[0038] Please see Figure 3 The rotary locking mechanism two has a semi-threaded locking structure and a slot 15-1 that adapts to the plate-like structure of the working head to facilitate the insertion of the plate-like structure into the hand tool. When the working head is inserted into the beauty hand tool, docking mechanism one and docking mechanism two are connected, and main body one and main body two are connected.

[0039] The semi-threaded locking structure has a limiting member 15-4, an elastic semi-threaded member 15-2, and a stop member 15-3. The stop member 15-3 is located at the tail end of the elastic semi-threaded member, and the head end of the elastic semi-threaded member 15-2 is located at the slot 15-1. The elastic semi-threaded member 15-2 is located above the limiting member 15-4. A receiving groove is formed between the elastic semi-threaded member and the limiting member, which allows the plate-like structure of the working head to rotate horizontally, and limits the plate-like structure in the vertical direction. The elastic semi-threaded member is arranged at an angle, and the angle causes the receiving groove between the elastic semi-threaded member and the limiting member to gradually decrease, thereby increasing the pressure on the plate-like structure from the elastic semi-threaded member when the working head rotates.

[0040] The outer surface of the slot 15-1 is flush with the outer surface of the limiting member 15-4 and is integrally formed. When the working head body is installed on the hand tool body, the outer surface of the slot 15-1 and the outer surface of the limiting member 15-4 respectively abut against the upper surface of the main body of the working head body.

[0041] When the working head is rotated and installed on the hand tool, the elastic semi-threaded component deforms under the pressure of the plate-like structure. The working head is fixed in position by the friction and pressure between the plate-like structure and the elastic semi-threaded component. After the working head is removed, the elastic semi-threaded component returns to its original position.

[0042] Preferably, the material of the elastic semi-threaded part is acrylic.

[0043] Preferably, the elastic semi-threaded part and the rotary locking mechanism are integrally formed.

[0044] When the working head rotates, the plate-like structure stops rotating after encountering the stop.

[0045] In use, after the working head is inserted into the hand tool and rotated horizontally, the plate-like structure remains in the receiving groove. A stop element limits the horizontal rotation of the working head, while the working head is fixed in position by the friction and pressure between the plate-like structure and the elastic semi-threaded component. Simultaneously, the receiving groove limits the vertical movement of the working head. Thus, the combined action of the stop element and the receiving groove ensures secure installation of the working head, as well as quick installation and removal.

[0046] Please see Figure 4 and Figure 5 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).

[0047] Preferably, a second vacuum tube (not shown) is axially provided in the middle of the handpiece body and is sealed and connected to the first vacuum tube.

[0048] Please see Figure 4 and Figure 5 Preferably, 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.

[0049] 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 T3. The sheet-like structure is located on the side wall of the vertical part of the step three and below the sealing ring three; the massage head is connected to the main body part two 18.

[0050] Please see Figure 4 and Figure 5 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 located on the side wall of the vertical part of the step three and below the sealing ring three. The sealing ring three Q3 is used for sealing when the structural member 12 is connected to the main body part two 18. Figure 5As 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. 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 and is used for the assembly connection between the structural component 12 and the massage head 11.
