[0002] Currently, international electrical standards are inconsistent. Electrical plugs and power sockets in most countries and regions cannot achieve a unified standard, which makes electrical appliances from one country or region unable to be used in another country or region due to the mismatch between plugs and sockets. With the need for the development of international business, culture, and other exchanges, the use of many household or portable electrical products in different regions of the world is becoming more and more common.

[0003] Although there are many styles of convertible plug structures on the market, during the long-term use of the convertible plug structure, after the plug is inserted and removed multiple times, the phenomenon of unstable electrical conductivity is likely to occur. Summary of the Utility Model

[0004] The purpose of the utility model is to improve the problem that the electrical conductivity is unstable after the existing plug structure is inserted and removed many times, and to provide a convertible plug structure and an aromatherapy machine.

[0005] The technical solutions to achieve the above purpose include the following:

A clamping groove is provided on the main body, the limiting block is arranged on the inner wall of the clamping groove, and the first conductive component is installed on the main body;

[0008] A conductive plug, the conductive plug includes a clamping block and a second conductive component. A limiting groove is provided on the circumference of the clamping block. The first end of the clamping block is matched with the clamping groove, and the limiting block is matched with the limiting groove;

[0009] The second conductive component is installed at the second end of the clamping block and is electrically connected to the first conductive component. The second conductive component has at least two first conductive heads.

[0010] In one embodiment, the first conductive component includes two second conductive heads. The two second conductive heads are installed on the main body and are arranged in the clamping groove, and the two second conductive heads are distributed along the circumference of the clamping groove;

[0011] The clamping block has two positioning grooves corresponding to the two second conductive heads. At least part of the second conductive head is accommodated in the positioning groove. The width of the positioning groove is greater than the width or outer diameter of the second conductive head, and the two second conductive heads are respectively electrically connected to the two first conductive heads.

[0012] In one embodiment, the main body includes a first base, a second base, and a conductive plate. An installation groove is formed on the first base, and the second base is snap-fitted with the installation groove.

[0013] The conductive plate is installed on the second base, and there is a first moving gap between the conductive plate and the second base. The second conductive head is installed on the conductive plate and is electrically connected to the conductive plate.

[0014] In one embodiment, the conductive base further has a dial block. A notch is provided on the outer wall of the second base. The dial block is installed at the notch, and there is a second moving gap between the dial block and the second base.

[0015] The outer surface of the dial block is higher than the outer surface of the second base.

[0016] In one embodiment, one side of the clamping block close to the clamping groove has a first avoidance groove for accommodating the dial block so that the dial block can move within the first avoidance groove.

[0017] In one embodiment, the conductive plug has a support block. The clamping block is installed at the first end of the support block, and both of the first conductive heads are installed at the second end of the support block, and at least part of the first conductive heads are disposed in the positioning groove of the clamping block.

[0018] The outer diameter of the clamping block is smaller than the outer diameter of the support block.

[0019] In one embodiment, the limiting groove includes a through groove and a sliding groove. Both the through groove and the sliding groove extend along the circumferential direction of the clamping block.

Compared with the existing clamping connection between the conductive socket and the conductive plug, after this conductive plug is clamped with the conductive socket, through rotation, after the limiting block and the limiting groove are matched, the fitting gap between the clamping block and the clamping groove is in a relatively stable state. Even if the number of plugging and unplugging operations is large, the clamping groove is enlarged by the clamping block or the clamping groove is deformed, the phenomenon that the clamping block and the clamping groove become loose can be avoided. The conductive plug and the conductive socket are arranged in a stable cooperation, so that the plug structure has stable conductive performance. Brief Description of the Drawings

[0043] The present utility model proposes a convertible plug structure 100, as Figures 1 to 4As shown in the figure, it includes: a conductive base 1 and a conductive plug 2. The conductive base 1 includes a main body 10, a first conductive component 113, and at least one limiting block 121. A card slot 123 is provided on the main body 10, and the limiting block 121 is arranged on the inner wall of the card slot 123. The first conductive component 113 is installed on the main body 10. The conductive plug 2 includes a clamping block 21 and a second conductive component 231. A limiting groove 212 is provided on the circumference of the clamping block 21. The first end of the clamping block 21 cooperates with the card slot 123, and the limiting block 121 cooperates with the limiting groove 212. The second conductive component 231 is installed at the second end of the clamping block 21 and is electrically connected to the first conductive component 113. The second conductive component 231 has at least two first conductive heads 2311. Specifically, the conductive base 1 is used for detachably clamping with the conductive plug 2. When the conductive plug 2 and the conductive base 1 are assembled, after the clamping block 21 cooperates with the card slot 123, then rotate the clamping block 21 or the main body 10 to make the limiting block 121 on the main body 10 be screwed into the limiting groove 212 of the clamping block 21, and the limiting block 121 abuts against the limiting groove 212. Compared with the existing clamping of the conductive base 1 and the conductive plug 2, after the conductive plug 2 is clamped with the conductive base 1, through the rotation method, after the limiting block 121 and the limiting groove 212 cooperate, the fitting gap between the clamping block 21 and the card slot 123 is in a relatively stable state. Even if the number of plugging and unplugging is large and the card slot 123 is enlarged by the clamping block 21 or the card slot 123 is deformed, the phenomenon that the clamping block 21 and the card slot 123 become loose can be avoided. The conductive plug 2 and the conductive base 1 are arranged in this way to have a stable cooperation, so that the plug structure 100 has a stable conductive performance.

[0044] Moreover, the second conductive component 231 has two or three first conductive heads 2311. In the adaptation of the conductive plug 2 and the conductive base 1, conductive plugs 2 with different numbers of first conductive heads 2311 can be made. The design of the conductive plug 2 can be based on the specification standards of different countries and regions. For example, two first conductive heads 2311 are suitable for two-hole sockets, and three first conductive heads 2311 are suitable for three-hole sockets; or the first conductive heads 2311 are set to be flat or cylindrical, so as to meet the electrical standards of different countries and regions and facilitate travelers to carry and use. In production and processing, only one type of conductive base 1 and multiple types of conductive plugs 2 need to be designed, and any conductive plug 2 can be respectively matched with the conductive base 1, improving the adaptability of the plug structure 100 and also improving the conductive stability of the plug structure 100.

[0045] In some embodiments, such as Figure 2As shown in the figure, the first conductive component 113 includes two second conductive heads 1131. The two second conductive heads 1131 are installed on the main body 10, arranged in the card slot 123, and the two second conductive heads 1131 are distributed along the circumferential direction of the card slot 123. The card block 21 has two positioning slots 211 corresponding to the two second conductive heads 1131. At least part of the second conductive head 1131 is accommodated in the positioning slot 211. The width of the positioning slot 211 is greater than the width or outer diameter of the second conductive head 1131, and the two second conductive heads 1131 are respectively electrically connected to the two first conductive heads 2311. Specifically, when the two second conductive heads 1131 correspond to the two positioning slots 211, when the card block 21 or the main body 10 is rotated and the limiting block 121 moves in the limiting slot 212, the second conductive head 1131 has a certain movement space in the positioning slot 211 to satisfy that the limiting block 121 abuts against the limiting slot 212 after rotation. Moreover, the positioning slot 211 is used to cooperate with the second conductive head 1311 to realize the positioning of the conductive plug 2 and the conductive seat 1 during installation, improve the assembly efficiency between the conductive plug 2 and the conductive seat 1, and improve the convenience of user use. When the conductive plug 2 and the conductive seat 1 are matched, the first conductive head 2311 is electrically connected to the second conductive head 1131, and the two first conductive heads 2311 are inserted into the socket to realize the conductive function of the plug structure 100.

[0046] Preferably, as Figure 2 and Figure 3As shown, the main body 10 includes a first base 11, a second base 12, and a conductive plate 124. An installation groove 111 is formed on the first base 11, and the second base 12 is snap-fitted with the installation groove 111; the conductive plate 124 is installed on the second base 12, and there is a first moving gap 125 between the conductive plate 124 and the second base 12. The second conductive head 1131 is installed on the conductive plate 124 and is electrically connected to the conductive plate 124. Specifically, when the second conductive head 1131 cooperates with the positioning groove 211, the second conductive head 1131 abuts against the first conductive head 2311, and the inner wall of the second conductive head 1131 or the positioning groove 211 presses the second conductive head 1131, and the second conductive head 1131 will press the conductive plate 124. Since there is a first moving gap 125 between the conductive plate 124 and the second base 12, the conductive plate 124 can generate a certain displacement after being pressed. The conductive plate 124 is generally made of conductive metal, and the conductive metal has a certain elasticity. After the conductive plate 124 is pressed, a reaction force is generated, and this reaction force acts on the second conductive head 1131, thereby further improving the contact stability between the second conductive head 1131 and the first conductive head 2311, and further improving the conductive stability between the first conductive head 2311 and the second conductive head 1131. Moreover, the first base 11 is used to support the second base 12 to improve the stability of the second base 12. There is an installation hole 114 on the first base 11, and this installation hole 114 is used for a fastener to pass through so that the first base 11 can be installed on a speaker, a charger, an aromatherapy machine 200, etc.

[0047] In some embodiments, as Figure 2 shown, the conductive base 1 further has a dial block 122. A notch is provided on the outer wall of the second base 12, and the dial block 122 is installed at the notch, and there is a second moving gap 126 between the dial block 122 and the second base 12; the outer surface of the dial block 122 is higher than the outer surface of the second base 12. Specifically, when the conductive base 1 is installed on the aromatherapy machine 200, the first base 11 is fixed to the outer shell 201 of the aromatherapy machine 200, the second base 12 is snap-fitted with the groove 203 of the outer shell 201, the second base 12 is located in the groove 203, the dial block 122 abuts against the inner wall of the groove 203, the dial block 122 is pressed, and there is a second moving gap 126 between the dial block 122 and the second base 12, and the dial block 122 can move in the notch, so that the outer surface of the dial block 122 and the outer surface of the second base 12 are on the same arc surface; when the second base 12 needs to be disassembled, push the dial block 122 to make it away from the inner wall of the groove 203, so as to pull out the second base 12 from the groove 203. The conductive base 1 arranged in this way can facilitate the replacement of the second base 12 when the second base 12 is damaged.

[0048] Preferably, as Figures 2 to 4As shown, the first avoidance groove 213 is provided on one side of the block 21 close to the slot 123. The first avoidance groove 213 is used to accommodate the shift block 122 so that the shift block 122 can move in the first avoidance groove 213. Specifically, the first seat body 11 also has a second avoidance groove 112. The first avoidance groove 213 and the second avoidance groove 112 are respectively located above and below the shift block 122. The main function of the first avoidance groove 213 and the second avoidance groove 112 is to avoid the shift block 122 so that the shift block 122 has a larger space for movement. When the conductive plug 2 is matched with the conductive seat 1, the second seat body 12 and the conductive plug 2 can be disassembled at the same time by squeezing the shift block 122. This design is mainly to replace the conductive plate 124 and the second conductive head 1131 on the second seat body 12 in time when the conductive instability occurs.

[0049] In some embodiments, Figure 4 As shown, the conductive plug 2 has a support block 22, a clamping block 21 is mounted on the first end of the support block 22, two first conductive heads 2311 are mounted on the second end of the support block 22, and the first conductive head 2311 is at least partially disposed in the positioning groove 211 of the clamping block 21; the outer diameter of the clamping block 21 is smaller than the outer diameter of the support block 22. Specifically, when the conductive plug 2 is matched with the conductive seat 1, the clamping block 21 is clamped with the clamping groove 123, the support block 22 is against the second seat body 12, and the support block 22 is used to support the first conductive head 2311, one end of the first conductive head 2311 passes through the support block 22 and the clamping block 21, and is disposed in the positioning groove 211 and against the second conductive head 1131. In the electrical standards of some regions, the conductive plug 2 can also be provided with a support seat 23, the first conductive head 2311 is cylindrical, the first conductive head 2311 is mounted on the support seat 23, and is used to adapt to the corresponding socket.

[0050] In some embodiments, Figure 4 As shown, the limiting groove 212 includes a through groove 2121 and a slide groove 2122. Both the through groove 2121 and the slide groove 2122 are extended along the circumference of the block 21. The through groove 2121 is connected to the slide groove 2122. The width of the through groove 2121 is smaller than the width of the slide groove 2122. Specifically, the width of the slide groove 2122 is greater than the width of the limit block 121. When the block 21 is engaged with the slot 123, the limit block 121 enters the slide groove 2122 through the through groove 2121. The clockwise rotation angle allows the limit block 121 to completely enter the slide groove 2122 and abut against the slide groove 2122. When the conductive plug 2 needs to be unplugged, the limit block 121 needs to be rotated counterclockwise to disengage from the slide groove 2122 so that the block 21 can be separated from the slot 123. The connection method designed in this way can further improve the connection stability between the block 21 and the main body 10, improve the conductive stability of the plug structure 100, and facilitate the disassembly of the conductive plug 2.

[0051] Preferably, Figure 2 andFigure 4 As shown, there are three limiting slots 212, and the three limiting slots 212 are distributed in the circumferential direction of the clamping block 21. The number of limiting blocks 121 corresponds to the number of limiting slots 212. Specifically, the three limiting slots 212 can be equally spaced in the circumferential direction of the clamping block 21, which can increase the connection points between the clamping block 21 and the main body 10, and further improve the stability after the conductive base 1 and the conductive plug 2 are connected.

[0052] In some embodiments, as Figure 5 and Figure 6 shown, the second conductive component 231 has three first conductive heads 2311, two of the first conductive heads 2311 are arranged in parallel, and two of the first conductive heads 2311 are respectively the zero-line connecting and live-line connecting terminals, and the remaining one first conductive head 2311 is the ground-line terminal. Specifically, the second conductive component 231 can have two first conductive heads 2311 or three first conductive heads 2311. Two first conductive heads 2311 are for two-hole plugs, and three first conductive heads 2311 are for three-hole plugs, which are used to adapt to different socket structures.

[0053] The present utility model also proposes an aromatherapy machine 200, as Figure 7 shown, including an atomization component 202, a housing 201, and the plug structure 100 as described above. The atomization component 202 is installed in the housing 201, and at least part of the plug structure 100 is installed in the housing 201 and is electrically connected to the atomization component 202. Specifically, when the plug structure 100 is applied to the aromatherapy machine 200, during the production of the aromatherapy machine 200, the aromatherapy machine 200 is equipped with a convertible plug structure 100. The conductive base 1 of the plug structure 100 is fixed to the housing 201, and the conductive plug 2 of the plug structure 100 has three different types and is packaged and sold together with the aromatherapy machine 200. In this way, when the manufacturer sells the aromatherapy machine 200 to different regions abroad, the aromatherapy machine 200 can be adapted to the sockets in that region during use, and the aromatherapy machine 200 can be used normally in different regions.

[0054] It should be noted that during the cooperation process of the conductive base 1 and the conductive plug 2 of the plug structure 100, after the clamping block 21 is clamped with the card slot 123 of the main body 10, the limiting block 121 is inserted into the limiting slot 212, and the clamping block 21 is rotated to make the limiting block 121 abut against the limiting slot 212. The clamping block 21 cannot be separated from the main body 10 without rotation, which improves the connection stability between the clamping block 21 and the main body 10, and at the same time improves the conductive stability between the conductive base 1 and the conductive plug 2. In other convertible plug electrical appliances, in order to achieve the technical effect of improving the conductive stability of the plug, the methods of clamping, rotating, and abutting two conductive components are within the protection scope of this embodiment.

[0055] When referring to the drawings, it is to explain the newly emerged features. To avoid the description being not concise enough due to repeated reference to the drawings, for the features that have been described clearly, the drawings are not cited one by one.

[0056] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solutions of the present utility model, and to completely describe the technical solutions, purposes and effects of the present utility model. The purpose is to enable the public to understand the disclosed content of the present utility model more thoroughly and comprehensively, and it does not limit the protection scope of the present utility model hereby.

[0057] The above embodiments are not exhaustive listings based on the present utility model. In addition, there may be multiple other embodiments not listed. Any substitution and improvement made on the basis of not violating the concept of the present utility model fall within the protection scope of the present utility model.
