[0007] Preferably, the buckle limiting plate, the buckle positioning mechanism, and the bottom surface of the transition groove form a receiving cavity for accommodating the buckle. After the buckle is inserted into the slide, the first transition part and the second transition part rotate relative to each other, so that the buckle enters the receiving cavity.

[0008] Preferably, the second adapter includes a positioning ring and a positioning post extending along the axial direction of the positioning ring, the fastener is disposed on the side wall of the positioning post, and the adapter groove is adapted to the positioning post.

[0009] Preferably, the positioning ring, the positioning post, and the first adapter are coaxial.

[0010] Preferably, the positioning ring is provided with a damping hole, and the first adapter is provided with a positioning hole at the upper edge of the adapter groove. The damping element is placed in the damping hole or the positioning hole. When the buckle abuts against the buckling mechanism, the damping element is simultaneously located in the damping hole and the positioning hole.

[0011] Preferably, the damping element is a steel ball.

[0012] Preferably, the first adapter portion is provided with at least one circuit connection hole, and the PIN pin of the male connector assembly for connecting the internal circuit extends through the circuit connection hole into the adapter groove; the second adapter portion includes a copper pillar for connecting the internal circuit of the female connector assembly, the copper pillar passes through the second adapter portion and is flush with the end face of the second adapter portion, and when the latching member abuts against the latching mechanism, the PIN pin connects to the copper pillar.

[0015] The present invention has the following advantages: In the adapter device of the present invention, after the buckle is inserted into the adapter groove, the first adapter part and the second adapter part rotate relative to each other. During the rotation, the buckle locking mechanism and the buckle are interference-fitted until the buckle abuts against the buckle positioning mechanism. The buckle locking mechanism falls into the locking groove and restricts the buckle from disengaging, thereby making the male and female connectors securely connected together. Compared with the current magnetic connection method, the adapter device of the present invention has a more stable connection, stronger impact resistance, and higher reliability during use.

[0016] In the above embodiments, the aromatherapy earphone case and the corresponding adapter embodiment belong to the same concept and thus have the same technical effect as the corresponding adapter embodiment, which will not be described again here.

[0027] like Figures 1 to 5 As shown, the adapter device of this embodiment includes a first adapter portion 100 disposed on the end face of the male connector assembly 10 and a second adapter portion 200 disposed on the end of the female connector assembly 20. The first adapter portion 100 includes an adapter groove 110 adapted to the second adapter portion 200. The side wall of the second adapter portion 200 is provided with at least two fasteners 210. The side wall of the fasteners 210 is provided with a locking groove 211. The side wall of the adapter groove 110 is provided with a fastening limiting plate 120 that restricts the axial movement of the fasteners 210. One end of the fastening limiting plate 120 is provided with a fastening positioning mechanism 130. Below the fastening limiting plate 120, there is a fastening locking mechanism 140 that connects to the side wall of the adapter groove 110. After the fasteners 210 are inserted into the adapter groove 110, they rotate until the fasteners 210 abut against the fastening positioning mechanism 130, and the fastening locking mechanism 140 falls into the locking groove 211.

[0028] The adapter in this embodiment can be used for various small household appliances that need to be disassembled. This embodiment takes the aromatherapy headphone charging case in CN222940894U as an example for illustration. It should be noted that the aromatherapy headphone charging case is only used for illustration in this embodiment and should not be construed as a limitation of this application. In other embodiments, any number of components can be connected to the adapter in this embodiment.

[0029] The first adapter 100 includes an adapter plane and an adapter groove 110 recessed from the adapter plane. The adapter plane is flush with the end face of the male connector assembly 10. The bottom of the adapter groove 110 of the first adapter 100 is provided with a threaded through hole. The first adapter 100 is fixed to the male connector assembly 10 by bolts.

[0030] The latching member 210 is a protrusion extending radially along the second adapter 200. Two, three or more can be provided on the second adapter 200 according to actual needs. In this embodiment, two latching members 210 are used as an example. The side of the latching member 210 is provided with a locking groove 211 adapted to the latching locking mechanism 140. When the latching locking mechanism 140 falls into the locking groove 211, the latching locking mechanism 140 locks the latching member 210 in the locking groove 211, restricting the latching member 210 from continuing to rotate.

[0031] When the second adapter 200 is inserted into the adapter groove 110 until its end face abuts the bottom of the adapter groove 110, the first adapter 100 or the second adapter 200 is rotated, causing the first adapter 100 and the second adapter 200 to rotate relative to each other. The latching member 210 rotates below the latching limiting plate 12, and the outer wall of the latching member 210 is press-fitted with the latching locking mechanism 140 until the latching member 210 abuts against the latching positioning mechanism 130, which then restricts the latching. As the fastener 210 continues to rotate, the latching locking mechanism 140 falls into the locking groove 211, restricting the fastener 210 from continuing to rotate. At the same time, the latching limiting plate 12 restricts the axial movement of the fastener 210, thereby locking the fastener 210 and preventing it from moving. The male connector assembly 10 and the female connector assembly 20 are connected. When disassembly is required, a force is applied that can separate the locking groove 211 from the latching locking mechanism 140, and the second adapter 200 can be pulled out after rotating in the opposite direction.

[0032] Compared to the current magnetic connection method, the adapter device in this embodiment connects the male and female connectors, which can withstand a 1.7-meter drop, high-intensity impact, and rolling test without falling apart. It can also be disassembled 8,000 to 10,000 times without significant changes. It has the advantages of more stable connection, stronger impact resistance, and higher reliability during use, making it suitable for occasions with requirements for strength and reliability.

[0033] In some possible embodiments, such as Figure 3As shown, the end of the buckle limiting plate 120 away from the buckle positioning mechanism 130 forms a slide 150 with the adjacent buckle positioning mechanism 130, and the buckle member 210 is inserted into the adapter groove 110 along the slide 150.

[0034] It is understood that the latching mechanism 130 is directly connected to the latching limiting part 120. Since both the latching mechanism 130 and the latching limiting part 120 can restrict the latching part 210, the latching part 210 can only slide in through the slide rail 150, thereby allowing the second adapter part 200 to be positioned and inserted into the adapter groove 110.

[0035] In some possible embodiments, such as Figure 3 As shown, the buckle limiting plate 120, the buckle positioning mechanism 130 and the bottom surface of the adapter groove 110 form a receiving cavity 160 for accommodating the buckle 210. After the buckle 210 is inserted into the slide 150, the first adapter 100 and the second adapter 200 rotate relative to each other, so that the buckle 210 enters the receiving cavity 160.

[0036] The opening of the receiving cavity 160 is directly opposite the slide 150. When the fastening member 210 slides into the slide 150, when the end face of the second transition part 200 abuts the bottom of the transition groove 110, the second transition part 200 will no longer be able to move axially. At this time, the first transition part 100 and the second transition part 200 are rotated relative to each other, and the fastening member 210 will enter the receiving cavity 160 until the fastening member 210 abuts the fastening positioning mechanism 130.

[0037] In some possible embodiments, such as Figure 5 As shown, the second adapter 200 includes a positioning ring 220 and a positioning post 230 extending along the axial direction of the positioning ring 220. A fastener 210 is provided on the side wall of the positioning post 230, and the adapter groove 110 is adapted to the positioning post 230.

[0038] Specifically, the positioning ring 220, the positioning post 230, and the first adapter 100 are coaxial. The positioning ring 220 is fixed to the end of the female connector assembly 20. When the positioning post 230 is inserted into the adapter groove 110 until the end face of the positioning post 230 abuts against the bottom surface of the adapter groove 110, the positioning ring 220 will abut against the upper edge of the adapter groove 110. When the first adapter 100 and the second adapter 200 rotate relative to each other, the first adapter 100 and the second adapter 200 rotate coaxially, thereby ensuring that the end face of the male connector assembly 10 always completely covers the end face of the female connector assembly 20.

[0039] In some possible embodiments, such as Figure 4 and Figure 5As shown, the positioning ring 220 is provided with a damping hole 221, and the first adapter 100 is provided with a positioning hole 170 at the upper edge of the adapter groove 110. The damping element is placed in the damping hole 221 or the positioning hole 170. When the buckle 210 abuts against the buckling mechanism 130, the damping element is simultaneously located in the damping hole 221 and the positioning hole 170.

[0040] In this embodiment, the damping element is specifically a steel ball, which is placed in the damping hole 221 or the positioning hole 170. When the positioning pin 230 is inserted into the adapter groove 110 until the end face of the positioning pin 230 abuts against the bottom surface of the adapter groove 110, the steel ball will have an interference fit with the positioning ring and / or the upper edge of the adapter groove 110. At this time, when the first adapter part 100 and the second adapter part 200 rotate relative to each other, the steel ball will generate friction, thereby improving the rotation feel. At the same time, when the rotation reaches the snap fastener 210 abutting and snapping into place... When mechanism 130 is in operation, damping hole 221 and positioning hole 170 will be coaxial, and steel ball will be located in both damping hole 221 and positioning hole 170. Steel ball will no longer be interference-fitted with the upper edge of positioning ring and / or adapter groove 110, resulting in a clear feel for stopping rotation and limiting reverse rotation to a certain extent. This enhances the connection between male connector assembly 10 and female connector assembly 20. In this embodiment, the rotation of the first adapter part 100 and the second adapter part 200 will be smooth and have a clear feel for stopping rotation when they rotate relative to each other, thus improving the user experience.

[0041] In some possible embodiments, such as Figure 4 and Figure 5 As shown, the first adapter 100 is provided with at least one circuit connection hole 180. The PIN pin 11 of the male connector 10 for connecting the internal circuit extends through the circuit connection hole 180 into the adapter groove 110. The second adapter 200 includes a copper pillar 21 for connecting the internal circuit of the female connector 20. The copper pillar 21 passes through the second adapter 200 and is flush with the end face of the second adapter 200. When the latching member 210 abuts against the latching mechanism 130, the PIN pin 11 connects to the copper pillar 21.

[0042] When connecting components with different functions, it is sometimes necessary to make electrical connections between different components. For example, in the aromatherapy headphone charging case of this embodiment, the aromatherapy component and the charging component need to be electrically connected. Therefore, in this embodiment, a circuit connection hole 180 is provided on the first adapter 100. The PIN pin 11 of the male connector 10, which is used to connect the internal circuit, extends through the circuit connection hole 180 into the adapter groove 110. Since the PIN pin 11 has a stroke compression function, when the positioning post 230 is inserted into the adapter groove 110 until the end face of the positioning post 230 abuts against the bottom surface of the adapter groove 110, the end face of the positioning post 230 will compress the PIN pin 11. After rotation, when the latching member 210 abuts against the latching mechanism 130, the PIN pin 11 connects to the copper post 21. At this time, because the stroke of the PIN pin 11 is compressed, its elastic potential energy will cause the PIN pin 11 to press tightly against the copper post 21, so that the PIN pin 11 and the copper post 21 are electrically connected, thereby making the internal circuit of the male connector 10 and the internal circuit of the female connector 20 electrically connected.

[0043] In some possible embodiments, there are three circuit connection holes 180, and the three circuit connection holes 180 are arranged in a 120-degree ring. There are also three copper pillars 21, which are also arranged in a 120-degree ring.

[0044] With three power supply paths arranged in a 120-degree ring, the circuit can be locked by rotating clockwise to prevent fooling. Power can only be supplied after the circuit is in position, preventing reverse or incorrect connection and damage to the circuit.

[0045] The stator core provided in the above embodiments of this application has at least the following characteristics:

[0046] 1. The locking groove 211 locks with the buckle locking mechanism 140, so that the male head assembly 10 and the female head assembly 20 are stably connected, and the male head assembly 10 does not fall apart after a 1.7-meter drop, high-intensity impact and rolling test. It can be repeatedly disassembled 8,000 to 10,000 times without significant wear, which is significantly better than the traditional magnetic / buckle structure.

[0047] 2. Placing the steel ball in the damping hole 221 or the positioning hole 170 improves the rotation feel when the first adapter 100 and the second adapter 200 rotate relative to each other, and also improves the stopping feel. It can also play a certain role in preventing reverse rotation after the rotation is in place.

[0048] 3. With three power supply paths arranged in a 120-degree ring, the circuit can be locked by rotating clockwise to prevent fooling. Power can only be supplied after the circuit is in position, preventing reverse or incorrect connection and damage to the circuit.

[0049] This utility model embodiment also provides an aromatherapy headphone case, including an aromatherapy component as a male connector component 10, a charging component as a female connector component 20, and the adapter device in the above embodiment. The aromatherapy component and the charging component can be detachably connected via the adapter device.

[0050] The aromatherapy earphone case connected by the adapter in the above embodiment has the advantages of more stable connection, strong impact resistance, and less tendency to fall apart. At the same time, it has a good rotation feel and a clear stopping feel during the adapter process, resulting in a better user experience. It can also achieve stable power supply between the aromatherapy component and the charging component.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
