[0013] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0014] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0015] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0016] See also Figures 1 to 4As shown, the magnetic connector 1 of the embodiment of the present application includes a first connector 10, and the first connector 10 includes a main body 11, a first connecting part 12 and a first magnetic part 13. The main body 11 is used to accommodate and / or fix the first connecting part 12 and the first magnetic part 13. At this time, the first connecting part 12 and the first magnetic part 13 are at least partially arranged in the main body 11, and the main body 11 is provided with a accommodating cavity 113. Since the first connecting part 12 needs to be connected to the second connecting part 22, it needs to be in a fixed state in the main body 11 to better ensure that it can be more stably connected. For the needs of aesthetics and safety, the first connecting part 12 and The first magnetic attraction portion 13 is at least partially accommodated in the main body 11, and the second connecting member 20 includes a base 21, a second connecting portion 22 and a second magnetic attraction portion 23. The first connecting member 10 and the second connecting member 20 are magnetically connected through the first magnetic attraction portion 13 and the second magnetic attraction portion 23, and the first connecting portion 12 is electrically connected to the second connecting portion 22; specifically, the first connecting portion 12 and the second connecting portion 22 can be a spring pin and a connecting plate, that is, when the first connecting portion 12 is a spring pin, the second connecting portion 22 is a connecting plate, and when the first connecting portion 12 is a connecting plate, the first connecting portion 12 is a connecting plate. The second connecting part 22 is a spring pin, which is not further defined herein. In actual design, it is set according to the needs of the specific usage scenario; the first magnetic attraction part 13 and the second magnetic attraction part 23 can both be magnets, or one can be a magnet and the other can be a metal sheet that can be attracted by a magnet. For example, when the first magnetic attraction part 13 is a magnet, the second magnetic attraction part 23 is a metal sheet that can be attracted by a magnet, or when the second magnetic attraction part 23 is a magnet, the first magnetic attraction part 13 is a metal sheet that can be attracted by a magnet, as long as the two can be attracted to each other; the base 21 includes a groove 211 adapted to the main body 11, and at this time the main body 11 is partially Wrapped in the groove 211, one is to protect the first connecting part 12 and the second connecting part 22 from being exposed to the outside when connected to cause a safety hazard, and the other is to make the first magnetic attraction part 13 on the first connecting part 10 and the second magnetic attraction part 23 on the second connecting part 20 more stable after connection and not easy to move in parallel. The groove 211 can be used as a limiting part of the main body 11 to limit the main body 11 so that it is displaced in a direction perpendicular to the first connecting part 10 and the second connecting part 20. The ratio of the depth of the groove 211 to the height of the main body 11 is not less than 0.5, and the maximum radius of the main body 11 is greater than the depth of the groove 211.The ratio of the depth of the groove 211 to the height of the main body 11 is not less than 0.5, which can better ensure that the main body 11 is not easy to fall off from the groove 211, but can also ensure that a certain force is applied to the main body 11, so that the main body 11 can be smoothly separated from the groove 211. Therefore, when the ratio of the depth of the groove 211 to the height of the main body 11 is controlled to be not less than 0.5, it can be ensured that it is not easy to fall off and can also ensure that the two are more convenient to separate. The ratio of the depth of the groove 211 to the height of the main body 11 can be 0.5, 0.6, 0.75, 0.8, 1, 1.2, etc., as long as it is not less than 0.5. A more suitable ratio can be selected according to the radius adaptability of the main body 11 to ensure that it is not easy to fall off and is easier to separate, and convenient to clean, carry or replace after separation.

[0017] In other embodiments, see Figure 4 As shown, the main body 11 includes a first shell 111 and a second shell 112, and a housing cavity 113 surrounded by the first shell 111 and the second shell 112, and the first connection part 12 and the first magnetic attraction part 13 are at least partially accommodated in the housing cavity 113. When the first connection part 12 is a spring pin, in order to enable the spring pin to be better connected to the wiring board, the height of the spring pin when it contacts the wiring board is higher than the height when the first connection part 12 and the second connection part 22 are connected, so that the spring pin can be more convenient to extend and retract, so as to better connect to the wiring board, and the first connection member 10 and the second connection member 20 will not be loosened due to insufficient contact or vibration, resulting in poor contact. Therefore, at this time, the first connection part 12 is partially accommodated in the housing cavity 113. When the first connection part 12 is a wiring board, it will be fully accommodated in the housing cavity 113 by the main body 11. As long as other methods can achieve full contact and connection between the first connection part 12 and the second connection part 22, they are also acceptable, and will not be elaborated on here.

[0018] In one embodiment, the first connection portion 12 includes a first contact 121 and a first connection line 122 connected to the first contact 121; the second connection portion 22 includes a second contact 221 and a second connection line connected to the second contact 221 (not shown in the figure, the second connection line can be collected together with the second contact 221 on the power board). The first contact 121 and the second contact 221 are in contact and connected to each other for power supply. Specifically, the first contact 121 can be a spring pin or a terminal board. Anyway, when the first contact 121 is a spring pin, the second contact 221 is a terminal board, and when the first contact 121 is a terminal board, the second contact 221 is a spring pin. There is no limitation here, and it is subject to the ability to achieve power supply. In this embodiment, the first contact member 121 is a spring pin as an example for explanation, that is, the second contact member 221 is a terminal board, that is, in order to prevent the first contact member 121 from containing multiple contact points and the contact position is inaccurate, all the contact points on the second contact member 221 are fixedly welded on a board during design, which can prevent inaccurate alignment, prevent the contact points from moving, increase the occurrence of poor contact, and better increase the stability of the connector.

[0019] Preferably, see Figure 4 As shown, when the first connecting portion 12 is a spring pin, a first notch 1111 is provided on the first shell 111, and a second notch 1121 is provided on the second shell 112. The first notch 1111 and the second notch 1121 enclose a first through-hole 1122, and the first through-hole 1122 is for the first connecting wire 121 to pass through. By respectively providing the first notch 1111 and the second notch 1112 on the first shell 111 and the second shell 112 to enclose the first through-hole 1122, the first connecting wire 121 can be better connected to the first contact member 121 during installation, and the installation is simpler and faster. In other embodiments, the first through-hole 1122 can also be provided on the first shell 111 or the second shell 112 separately to allow the first connecting wire 121 to pass through.

[0020] In another embodiment, see Figure 3 and Figure 4As shown, the base 21 is provided with a third notch 212, and the third notch 212 is partially arranged to enclose the first perforation 1122 to accommodate the first perforation 1122. Since the first perforation 1122 is arranged on the side of the first shell 111 and the second shell 112, it is necessary to arrange the third notch 212 on the groove 211 to adapt to the first perforation 1122, so as to better ensure that the first connector 10 is not easy to fall off from the second connector 20, and the first perforation 1122 is arranged on the side, which is the continuation of the first connector 10 and the second connector 20 on the side. Since the angle is the same as that of the first connector 10 and the second connector 20, the first connecting line 121 can be well protected from being easily broken. In other embodiments, in order to facilitate the separation of the first connector 10 and the second connector 20, the first perforation 1122 can also be arranged in a direction perpendicular to the first connector 10 and the second connector 20.

[0021] In other embodiments, see Figure 2 and 4 As shown, in order to fix the spring pin on the first connecting portion 12, the second housing 112 further includes a second through hole 1123, and there are multiple second through holes 1123. Since some electronic devices need to realize multiple functions, multiple lines need to be connected to realize more functions, so multiple second through holes 1123 can be set to allow multiple spring pins to pass through.

[0022] In other embodiments, a receiving groove 1124 is further provided on a surface of the second shell 112 away from the first shell 111 for receiving the first magnetic attraction portion 13 .

[0023] In other embodiments, see Figure 3 and Figure 4 As shown, the first shell 111 is further provided with a hand-held portion 1113; or, the first shell 111 is provided with a first opening 1112, and the hand-held portion 1113 is provided at the first opening 1112, for conveniently separating the first connecting member 10 and the second connecting member 20. That is, the hand-held portion 1113 can be integrally formed with the first shell 111, or can be detachably connected to the first shell 111, or can be non-integrally formed with the first shell 111 and fixedly connected with different materials, such as the hand-held portion 1113 is flexible, in order to facilitate the user's use and ensure a comfortable hand feel during use, thereby improving the user's use experience.

[0024] In other embodiments, see Figure 2 and Figure 4As shown, the base 21 is further provided with a positioning column 213, and the second connecting portion 22 is provided with a positioning hole 223 matching the positioning column 213. When the first contact member 121 on the first connecting portion 12 is a spring pin, the second contact member 221 on the second connecting portion 22 is fixedly welded on a board to form a terminal board for convenient connection. Therefore, if there are multiple second contact members 221 and multiple first contact members 121, the position of each contact member needs to be fixed, and the positioning column 213 and the positioning hole 223 can well achieve such a function. As long as the positioning column 213 is smoothly inserted into the positioning hole 223, positioning can be achieved to prevent wrong connection and displacement.

[0025] In another embodiment, see Figure 4 As shown, the base 21 is provided with a first fixing hole 214, the second connecting portion 22 is provided with a second fixing hole 224, and the second magnetic portion 23 is provided with a third fixing hole 231. The first fixing hole 214, the second fixing hole 224 and the third fixing hole 231 are aligned in the vertical direction, so that the base 21, the second connecting portion 22 and the second magnetic portion 23 can be fixed together with screws. In some other embodiments, the base 21, the second connecting portion 22 and the second magnetic portion 23 can also be fixed together on a product to reduce the exposure of the wire at the product end and facilitate the separation of the first connector 10 and the second connector 20.

[0026] The electronic equipment includes but is not limited to a hot water bag, a hand warmer, a uterus warmer, a knee warmer, a waist warmer, a massage device, a massage and heating integrated device, a warm baby, a belly warmer, a hair dryer, a humidifying device, a lighting device, a lighting and hair dryer integrated device, and a hair dryer and humidifying integrated device. When designing these devices, generally one end is only connected to the part of the magnetic suction connector without a power supply, which is convenient for cleaning, and the other end is connected to the control device and / or power supply, so this part is generally not recommended to be cleaned. Now some power-connected products on the market can also have good waterproof performance, but the more times they are cleaned, the later waterproof ability will gradually weaken, making it easier to malfunction during use, affecting the service life of electronic products. Therefore, it is not recommended to wash them frequently when it is not certain that the waterproof performance of these electronic devices is excellent enough. Therefore, using a magnetic suction connector in these electronic devices and products can better increase the service life of the product and improve safety performance. And after using the magnetic suction connector in the embodiment of the present application, its connection stability is better, it is not easy to fall off, and it will not be powered off midway, so that the use stability of the electronic equipment is better.

[0027] Specifically, Figure 5 Take this as an example to illustrate: Figure 5What is shown is a schematic diagram of the explosion of the structure of the heating device in the electronic device, where numbers 30 and 40 are the main body of the heating device, which can be made of cloth or plastic material and can be used as a protective body to protect the heating plate. The heating element is integrated with the second connecting part 22. This area is the heating area. On the market, more heating wires or heating plates are connected with wires and then connected to the heating plate or heating wire by soldering or other methods. In this application, the heating wire, the heating plate and the circuit board are integrated together, which can prevent the connection line from being broken due to violence during use, thereby causing a short circuit in the heating device, or causing a short circuit due to poor contact of the heating device. For aesthetic purposes, the second magnetic attraction part 23 is wrapped inside the main body of the heating device.

[0028] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, several deformations and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of this application shall be based on the attached claims.
