[0031] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0032] See Figure 1-9The figure shows a power plug with a switch, which includes a housing 1, a PCB board 2 installed in the housing 1, and a wire 3 connected to the PCB board 2 and extending outside the housing 1. The PCB board 2 is connected to a conductor 4 for conducting electricity, and the conductor 4 extends outside the housing 1. When in use, the wire 3 is connected to an electrical appliance, the power plug with a switch is inserted into a socket, and the conductor 4 is inserted into the socket to connect with the socket to achieve power supply. At this time, power is supplied to the appliance through the power plug, enabling the appliance to operate.

[0033] The PCB board 2 is provided with a switch 20 for controlling the power plug on and off, and the housing 1 is provided with a button 5 adapted to the switch 20. Pressing the button 5 controls the operation of the switch 20. In other words, the present invention adds a switch 20 for controlling the power plug on and off, and provides a button 5 on the housing 1 to control the operation of the switch 20. When power needs to be turned off, the user can directly press the switch 20 to control the power plug to turn off the power. The user does not need to walk to the appliance connected to the present invention and then press the appliance's power switch to turn off the appliance, making the present invention extremely convenient to use.

[0034] In order to achieve a better waterproof function, the present invention also makes the following design: the button 5 is a waterproof silicone button made of silicone, which includes a silicone body 51, a button portion 52 located in the middle of the silicone body 51 and corresponding to the switch 20, and a thin-walled elastic portion 53 integrally connected between the silicone body 51 and the button portion 52 so that the button portion 52 and the silicone body 51 form a seamless connection and can generate elastic deformation, and a mounting portion 54 integrally formed on the outside of the silicone body 51. The button portion 52 can be It moves up and down, and the thin-walled elastic part 53 provides a reset force. The mounting part 54 is fixedly connected to the shell 1. The button part 52 protrudes from the silicone body 51 and the thin-walled elastic part 53, and the upper end of the button part 52 passes upward through the hole 101 at the upper end of the shell 1 to be exposed on the upper end surface of the shell 1. The silicone body 51 also forms a sealed assembly with the lower end opening of the hole 101, so that the button 5 and the shell 1 can form a sealed assembly, which can effectively prevent water or water vapor from entering from between the button 5 and the shell, thereby achieving a better waterproof function. In addition, the button portion 52 is integrally connected to the silicone body 51 through a thin-walled elastic portion 53 that can generate elastic deformation. When the button portion 52 is pressed by a finger to drive the switch 20 to work, the thin-walled elastic portion 53 is squeezed downward by the button portion 52 and deformed. When the finger is released, the thin-walled elastic portion 53 is no longer subjected to the downward force. At this time, the thin-walled elastic portion 53 automatically resets, thereby driving the button portion 52 to move upward and reset, so that the upper end of the button portion 52 passes upward through the hole 101 at the upper end of the shell 1 to be re-exposed on the upper end surface of the shell 1 to facilitate the next press.

[0035] The thin-walled elastic portion 53 is in a trumpet shape with a small top and a large bottom, so that the thin-walled elastic portion 53 has better elasticity to form a support button portion 52, and has stronger elastic deformation ability to provide elastic restoring force to the button portion 52 without an applied force.

[0036] The lower end of the button portion 52 is also provided with a downwardly protruding portion 521 adapted to the switch, which can better drive the switch. The protrusion 521 is made of silicone and is integrally molded to the lower end of the button portion 52, or the protrusion 521 is made of hard rubber and is fixed to the lower end of the button portion 52 by gluing.

[0037] The assembly structure of the button 5 and the housing 1 is as follows:

[0038] An upward-opening annular groove 511 is formed at the upper end of the silicone body 51, and a convex ring body 102 is formed on the inner wall of the upper end of the shell 1 at the lower end opening of the hole 101. The convex ring body 102 is embedded and extruded in contact with the annular groove 511 to form a sealed assembly, thereby further ensuring the waterproof effect. The button part 52 passes through the convex ring body 102 to penetrate the hole 101, and a gap is formed between the button part 52 and the convex ring body 102 to facilitate the up and down movement of the button part 52. At the same time, a gap is also formed between the button part 52 and the hole 101 to facilitate the up and down movement of the button part 52.

[0039] In addition, the inner wall of the upper end of the shell 1 is also provided with several positioning columns 103, and the positioning columns 103 are provided with screw holes 104. The mounting portion 54 is provided with positioning holes 541 adapted to the positioning columns 103. The mounting portion 54 is sleeved on the outside of the positioning columns 103 through the mounting portion 54, thereby ensuring that the button is stably installed inside.

[0040] The PCB board 2 includes an electrically connected PCB main control board 21 and a second PCB board 22. The switch 20 is arranged on the second PCB board 22, and the second PCB board 22 is provided with a first through hole 221 corresponding to the screw hole 104. The second PCB board 22 is pressed and assembled with the silicone body 51 and the mounting portion 54, and the first screw 222 passes through the first through hole 221 and is screwed to the screw hole 104 to fix the second PCB board 22 and the button 5 in the housing 1. Its assembly structure is simple and stable.

[0041] In order to prevent the thin-walled elastic portion 53 from compressing air during the downward pressing process after the button portion 52 is pressed down, the following design is made: a plurality of exhaust grooves 512 are further provided at the lower end of the silicone body 51. After the lower end of the silicone body 51 contacts the upper end of the second PCB board 22, exhaust channels are formed between the exhaust grooves 512 and the second PCB board 22. After the button portion 52 is pressed down, the thin-walled elastic portion 53 will expel air from the cavity between the silicone body 51 and the second PCB board 22 through the exhaust channels during the downward pressing process, thereby avoiding compression of the air in the cavity between the silicone body 51 and the second PCB board 22, ensuring that the button portion 52 can be pressed down smoothly, and at the same time, the thin-walled elastic portion 53 can produce stable elastic deformation, thereby preventing the problem of resistance formed due to the compression of the space by the thin-walled elastic portion 53, which makes it impossible to press the button portion 52 smoothly.

[0042] In this embodiment, the housing 1 includes a bottom shell 11 and an upper cover 12 located on the bottom shell 11. The positioning column 103 is arranged on the inner wall of the upper cover 12. The second PCB board 22 and the button 5 are fixed in the upper cover 12. The PCB main control board 21 is locked in the bottom shell 11 by a second screw 211, and the wire 3 is welded and fixed to the PCB main control board 21 to form an electrical connection. The bottom shell 11 and the upper cover 12 are fixed together by ultrasonic fusion.

[0043] The conductor 4 is a metal part, which is integrated with the bottom shell 11 through in-mold injection molding.

[0044] In summary, the present invention adds a switch 20 for controlling the on / off of the power plug, and sets a button 5 on the housing 1 for controlling the operation of the switch 20. When the power needs to be turned off, the switch 20 can be directly pressed to control the power plug to turn off the power. The user does not need to walk to the side of the electrical appliance connected to the present invention and then press the power switch of the electrical appliance to turn off the electrical appliance, making the present invention extremely convenient to use. The button 5 of the present invention is a waterproof silicone button made of silicone. The upper end of the button portion 52 in the waterproof silicone button passes upward through the hole 101 at the upper end of the housing 1 to be exposed on the upper end surface of the housing 1, and the silicone body 51 also forms a sealed assembly with the lower end opening of the hole 101, so that the button 5 and the housing 1 form a sealed assembly, which can effectively prevent water or water vapor from entering between the button 5 and the housing, thereby achieving a better waterproof function. In addition, the button portion 52 is integrally connected to the silicone body 51 through a thin-walled elastic portion 53 that can generate elastic deformation. When the button portion 52 is pressed by a finger to drive the switch 20 to work, the thin-walled elastic portion 53 will be squeezed downward by the button portion 52 and deformed. When the finger is released, the thin-walled elastic portion 53 is no longer subjected to the downward force, and at this time, the thin-walled elastic portion 53 automatically resets.

[0045] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
