By setting two sets of spring connection structures, the stable on-off function of the push switch 5 can be achieved, and the output switching is quiet and silent, which improves the use performance.

[0032] The external structure of the foot switch structure 100 is made of metal parts, so that different surface treatments can be used to meet the structural strength requirements and the customer's high-end surface treatment requirements. Specifically, the pedal 1 and the lower cover 2 are both metal parts, preferably formed by machining of aluminum parts, and the pedal 1 and the lower cover 2 are subjected to anodized surface treatment. A compression space 11 is formed between the pedal 1 and the lower cover 2, and the connecting member 41 passes through the lower cover 2 and the compression space 11 from the inside of the lower cover 2 to connect with the pedal 1, and the first spring 42 is accommodated in the compression space 11. In this embodiment, the connecting member 41 and the first spring 42 are respectively provided with four groups, and the connecting member 41 is evenly arranged in the compression space 11, so that when the pedal 1 is stepped on, the force on the first spring 42 is uniform.

[0033] like Figure 3-Figure 5 As shown, the top of the lower cover 2 is provided with a through hole 22 communicating with the receiving cavity 21, and the second spring 6 extends out from the through hole 22. The inner side of the top of the pedal 1 is provided with an abutment portion 12 extending toward the through hole 22, and the second spring 6 contacts the abutment portion 12. The abutment portion 12 is provided with a groove 121 on the side facing the second spring 6, and the second spring 6 extends into the groove 121. The groove 121 further limits the position of the second spring 6, and the second spring 6 will not be offset when compressed. When the pedal 1 is stepped on, the second spring 6 is compressed, and the abutment portion 12 extends from the through hole 22 into the receiving cavity 21 and presses the push switch 5.

[0034] The top of the lower cover 2 is also provided with a plurality of through holes 23 located outside the through opening 22, and the plurality of through holes 23 are evenly distributed around the outside of the through opening 22.

A stopper 411 is provided at one end of the connecting member 41 away from the pedal 1, and the stopper 411 is accommodated in the lower cover 2. When the pedal 1 is stepped on, the first spring 42 is compressed, and the connecting member 41 moves downward along the through hole 23. When the pedal 1 is released, under the action of the first spring 42, the connecting member 41 moves upward along the through hole 23 until the stopper 411 abuts against the inside of the lower cover 2. At this time, the pedal 1 returns to its original position and is separated from the push switch 5.

[0035] like Figure 6-Figure 7 As shown, the foot switch structure 100 further includes a plug 7, the plug 7 is connected with a wire 71, the wire 71 is electrically connected to the push switch 5, the wire 71 is connected to the push switch 5 when the push switch 5 is pressed, and the wire 71 is disconnected from the push switch 5 when the push switch 5 is pressed again.

[0036] The bottom cover 3 is mounted on the end of the lower cover 2 away from the pedal 1. The bottom cover 3 is snap-connected with the lower cover 2 to make the appearance of the foot switch structure 100 more complete. A limiting portion 31 is provided on the side of the bottom cover 3 facing the lower cover 2 to limit the main body 51 to be installed on the bottom cover 3. Preferably, the main body 51 is snap-connected in the limiting portion 31. The limiting portion 31 is located in the center of the bottom cover 3 to facilitate the connection between the wire 71 and the main body 51. A limiting hole 32 for the wire 71 to pass through is also provided on the outer peripheral wall of the bottom cover 3. A plurality of limiting members 33 are also provided on the side of the bottom cover 3 facing the lower cover 2 to limit the wire 71 in the bottom cover 3. A through groove 24 aligned with the limiting hole 32 is also provided on the outer peripheral wall of the lower cover 2 to expose both ends of the wire 71 to the lower cover 2. The outer peripheral wall of the bottom cover 3 is provided with a cantilever 34 extending toward the lower cover 2 and a hook 35 protruding outward from the end of the cantilever 34, and the inner wall of the lower cover 2 is correspondingly provided with a receiving groove 25 for receiving the hook 35, so as to realize the assembly connection between the bottom cover 3 and the lower cover 2.

[0037] Specifically, the foot switch structure 100 is to first pass the connecting member 41 through the through hole 23, then sleeve the first spring 42 on the connecting member 41, and then insert the connecting member 41 into the mounting groove 13 to realize the assembly connection between the pedal 1 and the lower cover 2, then pass the wire 71 through the limiting hole 32, and then insert the wire 71 into the jack of the push switch 5, then insert the push switch 5 into the bottom cover 3, and then sleeve the second spring 6 on the push switch 5, and finally snap-connect the bottom cover 3 and the lower cover 2, and the foot switch structure 100 is assembled. When the pedal 1 is stepped on, the pedal 1 moves toward the side of the lower cover 2, and the first spring 42 and the second spring 6 are compressed until the pedal 1 squeezes the push switch 5, so that the push switch 5 is triggered. When the pedal 1 is released, under the action of the first spring 42 and the second spring 6, the pedal 1 moves away from the lower cover 2 and the pedal 1 returns to its original position; when the pedal 1 is stepped on again, the push switch 5 is disconnected, thereby realizing the on-off function of the foot switch structure 100.

[0038] In summary, the utility model connects the pedal 1 and the lower cover 2 through a connecting member 41, and a first spring 42 is sleeved on the connecting member 41, so that one end of the first spring 42 contacts the inner wall surface of the pedal 1 and the other end contacts the upper surface of the lower cover 2; at the same time, the second spring 6 is sleeved on the push switch 5 and extends out of the lower cover 2 to contact the inner wall surface of the pedal 1; when the pedal 1 is stepped on, the pedal 1 moves toward the side of the lower cover 2, and the first spring 42 and the second spring 6 are compressed until the pedal 1 squeezes the push switch 5, so that the push switch 5 is triggered. Compared with the prior art, the utility model can not only realize the stable on-off function of the foot switch, but also is silent when the output is switched, thereby improving the performance. In addition, by setting the pedal 1 and the lower cover 2 as metal parts, the utility model can meet the requirements of structural strength, and at the same time, it can also meet the needs of customers for high-end surface treatment by performing different surface treatments on the pedal 1 and the lower cover 2.
