The wired power supply mode is relatively reliable, and some household appliances are also equipped with an AC / DC adapter on their power cords. Due to the limitations of power cords, adapters, and sockets, it is difficult for household appliances to be easily moved from one place to another, resulting in low convenience in the use of household appliances. Therefore, the existing solution proposes to make household appliances tailless and adapter-free in response to the above situation, that is, to remove power cords and adapters to facilitate the movement of household appliances.
[0003] However, in the existing solution, the tailless household appliance is to add a functional interface structure to the household appliance for power supply, and then the charging cable on the functional interface structure is inserted into the power socket of the household appliance for power supply. At this time, the functional interface structure cannot be stably fixed on the household appliance, but is suspended on the household appliance by the charging cable, and the charging cable is easy to fall off from the power socket; or a fixed structure is specially set on the household appliance for fixing the functional interface structure to prevent the functional interface structure from falling off, but this will add an extra production step, resulting in low production efficiency, increased production costs and other problems.

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.
[0051] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.
[0052] In one embodiment, referring to the attached Figure 1-2 The utility model proposes a functional interface structure, including a shell 10, a battery 20 located in the shell 10 and an interface 30 located on one side of the shell 10, wherein the interface 30 is electrically connected to the battery 20 and can rotate relative to the shell 10.
[0053] The outer end of the interface 30 that rotates outward is recessed inward to form a receiving cavity 31, and the receiving cavity 31 is used to match and be inserted into the power socket 40 of the household appliance to provide power.
[0054] When the household appliance needs to be used, the interface 30 of the functional interface structure proposed in the utility model is rotated to electrically connect the interface 30 to the battery 20, and then the outer end of the interface 30 provided with the accommodating cavity 31 is correspondingly inserted into the power socket 40 of the household appliance, so that the electric energy in the battery 20 flows into the household appliance through the interface 30 and the power socket 40, so that the household appliance can operate normally.
[0055] Moreover, the functional interface structure of the present invention is inserted into the power socket 40 of the household appliance through the interface 30 and is stably placed. Compared with the solution in the prior art that the functional interface structure is suspended in the power socket of the household appliance through the charging cable, the interface 30 of the functional interface structure of the present invention can be stably inserted into the power socket 40 of the household appliance, and the interface 30 will not easily fall off from the power socket 40.
[0056] Compared with the solution of additionally setting a fixed structure on the household appliance to fix the functional interface structure, the functional interface structure of the utility model does not need to set an additional fixed structure. It only needs to insert the interface 30 into the power socket 40 of the household appliance. This will not increase the production steps of the original household appliance, and thus will not cause problems such as low production efficiency and increased production costs, so that the household appliance can maintain the original low production efficiency and production cost.
[0057] In order to enable the battery 20 to provide a power supply voltage, refer to the attached Figure 1 , the housing 10 is also provided with a positive contact sheet 11 and a negative contact sheet 12, and the positive contact sheet 11 and the negative contact sheet 12 are both electrically connected to the battery 20. Of course, the housing 10 is also provided with a charging port (not shown, the same in the whole text) corresponding to the battery 20, and the charging port is electrically connected to the battery 20. When the battery 20 is low on power, the charging port can be connected to the mains socket through a matching charging cable to charge, thereby preventing the battery 20 from being low on power.
[0058] Among them, the specific connection structure between the interface 30 and the battery 20 is: the inner end of the interface 30 away from the opening of the accommodating cavity 31 extends outward with a positive contact head 32 and a negative contact head 33, and the positive contact head 32 and the negative contact head 33 can both be electrically connected to the battery 20.
[0059] The positive electrode contact sheet 11 can be electrically connected to the positive electrode contact head 32 , and the negative electrode contact sheet 12 can be electrically connected to the negative electrode contact head 33 .
[0060] In order to make the positive contact sheet 11 better fit the positive contact head 32 and the negative contact sheet 12 better fit the negative contact head 33 , both the positive contact sheet 11 and the negative contact sheet 12 can undergo elastic deformation.
[0061] In order to reduce arcing during the process of powering on or off the interface 30, refer to the attached Figure 2 , the length of the positive contact head 32 is greater than the length of the negative contact head 33. At this time, the positive contact head 32 and the negative contact head 33 are arranged up and down, and the negative contact head 33 is closer to the battery 20 than the positive contact head 32; at the same time, the positive contact sheet 11 and the negative contact sheet 12 in the housing 10 are not in the same plane, and the negative contact sheet 12 is closer to the interface 30 than the positive contact sheet 11, and the negative contact sheet 12 is closer to the battery 20 than the positive contact sheet 11.
[0062] In this way, when the positive contact head 32 and the negative contact head 33 are connected to the corresponding positive contact sheet 11 and the negative contact sheet 12, the positive contact head 32 and the negative contact head 33 can sequentially contact the positive contact sheet 11 and the negative contact sheet 12. In this embodiment, it is preferred that the negative contact head 33 first contacts the negative contact sheet 12, and then the positive contact head 32 contacts the positive contact sheet 11. In this way, arcing can be reduced during the power-on or power-off process between the interface 30 and the battery 20, avoiding damage to the functional interface structure.
[0063] At the same time, in order to further reduce the arcing phenomenon during the process of powering on or off, the interface 30 in this embodiment is provided with a positive contact head 32 and a negative contact head 33, and the inner ends are also wrapped with an insulating layer 36, so that when the interface 30 is rotated 90°, the insulating layer 36 will first touch the negative contact piece 12, causing the negative contact piece 12 to deform, and then the negative contact head 33 will contact the negative contact piece 12, and then the positive contact head 32 will contact the positive contact piece 11.
[0064] Of course, in other embodiments, refer to the attached Figure 6 , the length of the positive contact head 32 is less than that of the negative contact head 33, and the positive contact head 32 is closer to the battery 20; at the same time, the positive contact sheet 11 and the negative contact sheet 12 in the housing 10 are not in the same plane, and the positive contact sheet 11 is closer to the interface 30 than the negative contact sheet 12, and the positive contact sheet 11 is closer to the battery 20 than the negative contact sheet 12. Then, when the positive contact head 32 and the negative contact head 33 can sequentially contact the positive contact sheet 11 and the negative contact sheet 12, the insulating layer 36 will first touch the positive contact sheet 11, and the positive contact sheet 11 will be deformed, and then the positive contact head 32 will first contact the positive contact sheet 11, and the negative contact head 33 will then contact the negative contact sheet 12, which is conducive to electrical contact and further reduces the arcing phenomenon that occurs during the process of powering on or off the interface 30 and the battery 20.
[0065] Among them, refer to the attached Figure 3 The specific connection structure of the interface 30 connected to the power socket 40 of the household appliance is as follows: the inner side wall of the accommodating cavity 31 close to the opening is provided with a first positive contact surface 34, the first positive contact surface 34 protrudes from the inner side wall of the accommodating cavity 31 and can undergo elastic deformation; the first positive contact surface 34 is electrically connected to the positive contact head 32; the outer side wall of the interface 30 is covered with a first negative contact surface 35, the first negative contact surface 35 is electrically connected to the negative contact head 33. Of course, the first positive contact surface 34 can also be located in the middle of the inner side wall of the accommodating cavity 31 or on the side away from the opening, which is not limited here.
[0066] Specifically, a metal conductor 37 is also provided in the interface 30, one end of the metal conductor 37 is connected to the first positive contact surface 34, and the other end of the metal conductor 37 is connected to the positive contact head 32, so that the first positive contact surface 34 will be electrically connected to the positive contact head 32 through the metal conductor 37.
[0067] Among them, refer to the attached Figure 2 In order to enable the interface 30 to be better and more stably connected to the power socket 40 of the household appliance, the maximum rotation angle of the interface 30 relative to the housing 10 is 90°.
[0068] Specifically, a rotary switch 38 is provided on one side of the interface 30 close to the positive contact head 32. When the interface 30 needs to be rotated, the rotary switch 38 is pressed continuously. When the interface 30 does not need to be rotated, the finger is removed and the rotary switch 38 is no longer pressed. The rotary switch 38 in this article is prior art and will not be described in detail here.
[0069] In one embodiment, the utility model further provides a household appliance, comprising the functional interface structure described above.
[0070] Among them, refer to the attached Figure 3-5 The specific connection relationship between the power socket 40 of the household appliance and the interface 30 is: the household appliance also includes a power socket 40 that is recessed inward, a connecting column 41 extends outward from the bottom wall of the power socket 40, and the connecting column 41 is located inside the power socket 40.
[0071] The surface of the connection column 41 is covered with a second positive contact surface 42 , and the inner side wall of the power socket 40 is covered with a second negative contact surface 43 .
[0072] When the interface 30 is matched and inserted into the power socket 40 and the connecting column 41 is matched and inserted into the accommodating cavity 31 , the second positive contact surface 42 is electrically connected to the first positive contact surface 34 , and the second negative contact surface 43 is electrically connected to the first negative contact surface 35 .
[0073] The utility model can realize tailless household appliances by correspondingly inserting the interface 30 of the functional interface structure into the power supply socket 40 of the household appliance, making it convenient for the household appliance to be easily moved from one place to another, and no longer subject to the length limit of the power cord and the installation limit of the socket, thus greatly improving the convenience of using the household appliance. At the same time, the battery 20 is used to supply DC power to the household appliance, and it is no longer necessary to use an adapter to convert external AC power into DC power for use by the household appliance, thus realizing the de-adaptation of the household appliance.
[0074] The usage process of the household appliance of the utility model:
[0075] When the household appliance needs to be used, the interface 30 of the functional interface structure is first rotated 90° so that the outer end of the interface 30 with the accommodating cavity 31 faces outward, and then the interface 30 rotated 90° is inserted into the power socket 40. At the same time, the positive contact head 32 and the negative contact head 33 at the inner end of the interface 30 contact the positive contact sheet 11 and the negative contact sheet 12 respectively, and the connecting column 41 is matched and inserted into the accommodating cavity 31, the second negative contact surface 43 contacts the first negative contact surface 35, and the second positive contact surface 42 contacts the first positive contact surface 34. In this way, the battery 20 starts to discharge and supply power to the household appliance, so that the household appliance can operate normally.
[0076] When the household appliance is not needed, the interface 30 is removed from the power socket 40 and then rotated 90° in the opposite direction to reset. At this time, the positive contact head 32 and the negative contact head 33 are separated from the corresponding positive contact sheet 11 and the negative contact sheet 12 respectively.
[0077] In other embodiments, refer to the attached Figure 6-8 The utility model also proposes another functional interface structure, including a shell 10, a battery 20 located in the shell 10, and an interface 30 located on one side of the shell 10, wherein the interface 30 can rotate relative to the shell 10, and the maximum rotation angle is 90°; the end of the interface 30 that rotates outward is recessed inward to form a receiving cavity 31, and the receiving cavity 31 is used to insert a power socket 40 of a household appliance and supply power; the inner end of the interface 30 away from the opening of the receiving cavity 31 extends outward with a positive contact head 32 and a negative contact head 33, and the length of the positive contact head 32 is less than the length of the negative contact head 33, and the positive contact head 32 is closer to the battery 20.
[0078] The shell 10 is also provided with a positive contact piece 11 and a negative contact piece 12 that can undergo elastic deformation. The positive contact piece 11 and the negative contact piece 12 are both electrically connected to the battery 20, and the positive contact piece 11 can be electrically connected to the positive contact head 32 accordingly, and the negative contact piece 12 can be electrically connected to the negative contact head 33 accordingly.
[0079] A first negative electrode contact surface 35 is provided on the inner wall of the accommodating cavity 31 close to the opening. The first negative electrode contact surface 35 protrudes from the inner wall of the accommodating cavity 31 and can undergo elastic deformation. The first negative electrode contact surface 35 is electrically connected to the negative electrode contact head 33 through a metal conductor 37; the outer wall of the interface 30 is covered with a first positive electrode contact surface 34, and the first positive electrode contact surface 34 is electrically connected to the positive electrode contact head 32.
[0080] The household appliance also includes an inwardly recessed power socket 40, a bottom wall of which has a connecting column 41 extending outwardly, and the connecting column 41 is located inside the power socket 40, a surface of the connecting column 41 is covered with a second negative electrode contact surface 43, and an inner side wall of the power socket 40 is covered with a second positive electrode contact surface 42.
[0081] Therefore, when the household appliance needs to be used, the interface 30 of the functional interface structure is first rotated 90 degrees, so that the outer end of the interface 30 with the accommodating cavity 31 faces outward, and at the same time, the positive contact head 32 and the negative contact head 33 at the inner end of the interface 30 contact the positive contact sheet 11 and the negative contact sheet 12 respectively, and then the interface 30 is correspondingly inserted into the power supply socket 40 of the household appliance. At this time, the connecting column 41 is matched and inserted into the accommodating cavity 31, the second negative contact surface 43 contacts the first negative contact surface 35, and the second positive contact surface 42 contacts the first positive contact surface 34, so that the battery 20 can supply power to the household appliance, so that the household appliance can operate normally, and the interface 30 of the functional interface structure can be stably connected to the power supply socket 40 of the household appliance, and the interface 30 will not easily fall off from the power supply socket 40. There is no need to add an additional fixing structure to the household appliance, so that the production steps of the original household appliance will not be increased, and thus problems such as low production efficiency and increased production costs will not occur.
[0082] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments.
