[0006] Preferably, the anti-backflow structure includes a switch installation port and a push-type switch, and the switch installation port is arranged on the surface of the triangular fork.
[0007] Preferably, a push-type switch is installed inside the triangular fork, and the end of the push-type switch extends to the outside of the switch installation port, and when the triangular fork is disconnected or unplugged, the push-type switch is used to immediately cut off the power to prevent current from occurring.
[0008] Preferably, the fool-proof structure is composed of an upper positioning column, a middle positioning column and a lower positioning column.

[0009] Preferably, a middle positioning post and a lower positioning post are provided on one side of the upper positioning post, and the middle positioning post and the lower positioning post are integrally injection-molded on the surface of the male head.
[0010] Preferably, the upper positioning column is asymmetrical to the middle positioning column and the lower positioning column about the center line of the male head, and when the male head is plugged in, foolproofing is achieved through the asymmetrical relationship between the upper positioning column, the middle positioning column and the lower positioning column.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the household energy storage anti-backflow plug realizes the anti-backflow function by arranging an anti-backflow structure on the male head. Specifically, by utilizing the push-type switch arranged at the male head, when the plug is suddenly disconnected or unplugged non-human or even human, the push-type switch will immediately cut off the power, because sometimes there may be a moment when current may be generated, and at this time the push-type switch can prevent the current from flowing back; at the same time, the anti-fool function is realized by arranging an anti-fool structure on the triangular fork. Specifically, since the upper positioning column and the middle positioning column and the lower positioning column are asymmetrical with respect to the center line of the male head, when the male head is plugged in, the anti-fool function can be realized by the asymmetric relationship between the upper positioning column and the middle positioning column and the lower positioning column, thereby avoiding the reverse plugging phenomenon.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present invention, unless otherwise clearly stipulated and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0018] The structure of the household energy storage anti-backflow plug provided by the utility model is as follows Figure 1 as well as Figure 3 As shown, it includes a male plug 1 and a triangular fork 2. The male plug 1 and the triangular fork 2 are electrically connected via a power cord 3. The surface of the triangular fork 2 is connected with an anti-backflow structure 4, which is used to cut off the power when the plug is disconnected or unplugged to achieve the anti-backflow function of the plug. The anti-backflow structure 4 includes a switch mounting port 41 and a push-type switch 42. The switch mounting port 41 is provided on the surface of the triangular fork 2. The push-type switch 42 is installed inside the triangular fork 2, and the end of the push-type switch 42 extends to the outside of the switch mounting port 41. When the triangular fork 2 is disconnected or unplugged, the push-type switch 42 is used to immediately cut off the power to prevent the occurrence of current.
[0019] During implementation, the anti-backflow function is achieved by providing an anti-backflow structure 4 on the male connector 1. Specifically, by utilizing the push-type switch 42 provided at the male connector 1, when the plug is suddenly disconnected or unplugged, whether by human intervention or not, the push-type switch 42 will immediately cut off the power supply. Because current may be generated for a moment sometimes, the push-type switch 42 can prevent the current from flowing back at this time.
[0020] Further, if Figure 2 as well as Figure 4As shown, the surface of the male plug 1 is provided with an anti-foolproof structure 5, which is used for anti-foolproof work when the plug is plugged in to avoid the phenomenon of reverse plugging. The anti-foolproof structure 5 is composed of an upper positioning column 51, a middle positioning column 52 and a lower positioning column 53. There are two groups of upper positioning columns 51, and the two groups of upper positioning columns 51 are integrally injection-molded on the surface of the male plug 1. A middle positioning column 52 and a lower positioning column 53 are provided on one side of the upper positioning column 51, and the middle positioning column 52 and the lower positioning column 53 are both integrally injection-molded on the surface of the male plug 1. The upper positioning column 51 and the middle positioning column 52 and the lower positioning column 53 are asymmetrical about the center line of the male plug 1, and when the male plug 1 is plugged in, the anti-foolproof work is achieved through the asymmetrical relationship between the upper positioning column 51 and the middle positioning column 52 and the lower positioning column 53.
[0021] During implementation, the anti-foolproof function is achieved by providing an anti-foolproof structure 5 on the triangular fork 2. Specifically, since the upper positioning column 51 and the middle positioning column 52 and the lower positioning column 53 are asymmetrical with respect to the center line of the male connector 1, when the male connector 1 is plugged in, the anti-foolproof function can be achieved through the asymmetrical relationship between the upper positioning column 51 and the middle positioning column 52 and the lower positioning column 53, thereby avoiding the reverse insertion phenomenon.
[0022] Working principle: When in use, the anti-backflow function is achieved by setting an anti-backflow structure 4 on the male plug 1. Specifically, the push-type switch 42 set at the male plug 1 is used. When the plug is suddenly disconnected or unplugged without human intervention or even by human intervention, the push-type switch 42 will immediately cut off the power. Because current may be generated for a moment sometimes, the push-type switch 42 can prevent the current from flowing back at this time.
[0023] At the same time, an anti-mistake function is achieved by providing an anti-mistake structure 5 on the triangular fork 2. Specifically, since the upper positioning column 51 and the middle positioning column 52 and the lower positioning column 53 are asymmetrical with respect to the center line of the male connector 1, when the male connector 1 is plugged in, the anti-mistake function can be achieved through the asymmetrical relationship between the upper positioning column 51 and the middle positioning column 52 and the lower positioning column 53, thereby avoiding the reverse insertion phenomenon.
[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
