[0021] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0022] Please refer to Figures 1 - 3 , the impact current generator 1 of the present invention includes a generator body 11, a capacitor 12 and a sound insulation component 13. A conductive column 121 is provided on the capacitor 12. The sound insulation component 13 includes two sound insulation boards 131 and at least two layers of sound insulation glass 132. The two sound insulation boards 131 are respectively covered on the upper and lower sides of the at least two layers of sound insulation glass 132. The generator body 11 and the capacitor 12 are both installed on the lower sound insulation board 131. The at least two layers of sound insulation glass 132 surround the generator body 11 and the capacitor 12. Accommodating grooves 1311 are formed around the surface of the sound insulation board 131 close to the sound insulation glass 132. The number of the accommodating grooves 1311 is equal to the number of the sound insulation glass 132 and the size is adapted to the size of the sound insulation glass 132. A protruding sound insulation cylinder 1312 is provided on the upper sound insulation board 131. The sound insulation cylinder 1312 is located above the conductive column 121 and is concentric with the conductive column 121.

[0023] By installing the generator body 11 and the capacitor 12 on one of the sound insulation boards 131, surrounding the at least two layers of sound insulation glass 132 around the generator body 11 and the capacitor 12, connecting the sound insulation glass 132 with the sound insulation board 131, and covering the other sound insulation board 131 on the sound insulation glass 132, the generator body 11 and the capacitor 12 can be enclosed under the joint action of the sound insulation glass 132 and the sound insulation board 131, so as to play a role in isolating noise when the impact current generator 1 works, and at the same time, it can also isolate dust and impurities in the air from falling on the conductive column 121 and affecting the normal use of the impact current generator 1.

[0024] By arranging the sound insulation cylinder 1312 on the sound insulation board 131 and making the position of the sound insulation cylinder 1312 correspond to the position of the conductive column 121, the distance between the conductive column 121 and the sound insulation board 131 is increased under the action of the sound insulation cylinder 1312. When the impulse current generator 1 works, the generated current can enter the sound insulation cylinder 1312, preventing the current from contacting the sound insulation board 131 and causing damage or breakdown to the sound insulation board 131. At the same time, under the action of the sound insulation cylinder 1312, the noise of the current can be suppressed, reducing the noise pollution of the current.

[0025] In the above embodiment, both the sound insulation board 131 and the sound insulation cylinder 1312 are made of gypsum board. The sound insulation glass 132 is provided with two layers. There are two mutually spaced receiving grooves 1311 around the sound insulation board 131. The two layers of sound insulation glass 132 are respectively located in the two receiving grooves 1311, so that the sound insulation glass 132 is assembled and connected to the sound insulation board 131, and the generator body 11 and the capacitor 12 are enclosed in the space surrounded by the sound insulation board 131 and the sound insulation glass 132, providing sound insulation and dust prevention functions for the impulse current generator 1.

[0026] In the embodiment of the present utility model, the sound insulation component 13 further includes a bent pipe 133. One end of the bent pipe 133 passes through the side wall of the sound insulation board 131, and the other end passes through the side wall between the two receiving grooves 1311 and extends into the gap between the two layers of sound insulation glass 132. After connecting the bent pipe 133 to an external air extraction device, the space between the two layers of sound insulation glass 132 can be evacuated through the bent pipe 133, so as to insulate the generator body 11 under the action of the two layers of sound insulation glass 132 and the vacuum layer, reducing the noise when the impulse current generator 1 works.

[0027] In the above embodiment, the sound insulation component 13 further includes a one-way valve. The one-way valve is arranged at one end of the bent pipe 133 passing through the side wall of the sound insulation board 131, so as to prevent air from flowing back into the two layers of sound insulation glass 132 and affecting the sound insulation effect of the sound insulation component 13 when evacuating the position between the two layers of sound insulation glass 132 through the bent pipe 133.

[0028] In the embodiment of the present utility model, a sealing strip is arranged on the inner wall of the receiving groove 1311. After the sound insulation glass 132 is inserted into the receiving groove 1311, it fits with the sealing strip, so as to increase the sealing performance between the sound insulation glass 132 and the sound insulation board 131, thereby improving the sound insulation effect of the sound insulation component 13 and reducing the noise of the impulse current generator 1.

[0029] In an embodiment of the present utility model, the sound insulation component 13 further includes a mounting frame 134 and a movable window 135. An installation hole is formed on one side of the sound insulation glass 132. The mounting frame 134 is fixed to the installation hole, and the movable window 135 is hinged to the mounting frame 134. When it is necessary to operate and debug the generator body 11, the movable window 135 can be opened from the mounting frame 134, facilitating the operator to debug the generator body 11 inside the sound insulation component 13. After the debugging is completed, by rotating the movable window 135 and covering the movable window 135 on the mounting frame 134, the generator body 11 and the capacitor 12 are enclosed within the sound insulation glass 132 and the sound insulation board 131, enabling the sound insulation component 13 to suppress the noise generated by the generator body 11, achieving the effects of noise reduction and dust prevention.

[0030] In an embodiment of the present utility model, sealing glue is provided around the mounting frame 134. The sealing glue is filled on the two layers of sound insulation glass 132 around the installation hole to seal the installation hole between the two layers of sound insulation glass 132 under the action of the sealing glue, facilitating the vacuum pumping operation on the position between the two layers of sound insulation glass 132 through the bending pipe 133, thereby improving the sound insulation effect of the sound insulation component 13. At the same time, after the mounting frame 134 is fixed to the installation hole, it can prevent a gap from being generated between the mounting frame 134 and the installation hole, resulting in a reduction in the sound insulation effect between the two layers of sound insulation glass 132.

[0031] In an embodiment of the present utility model, the outer surface of the mounting frame 134 is flush with the surface of the outer layer of sound insulation glass 132, and the inner surface of the mounting frame 134 is flush with the surface of the inner layer of sound insulation glass 132 to improve the aesthetics of the mounting frame 134 installed on the installation hole, preventing the mounting frame 134 from protruding or recessing on the sound insulation glass 132 and affecting the overall aesthetics of the sound insulation component 13. The thickness of the movable window 135 is adapted to the thickness of the mounting frame 134, so that after the movable window 135 is closed, the surface of the movable window 135 is flush with the surface of the mounting frame 134, further improving the overall aesthetics of the sound insulation component 13.

[0032] In an embodiment of the present utility model, a handle 1351 is fixed on the outer side surface of the movable window 135. When it is necessary to open or close the movable window 135, the operator can push or pull the handle 1351 to open or close the movable window 135. By pulling the handle 1351, the movable window 135 can be opened, facilitating the operator to perform debugging operations on the generator body 11. By pushing the handle 1351, the movable window 135 can be closed, enabling the sound insulation component 13 to play a role in sound insulation and noise reduction for the generator body 11.
