[0019] The following further describes the present utility model in detail in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0020] The specific implementation process of the present utility model is as follows:

[0021] Such as Figures 1 to 3As shown in the figure, a magnetically controlled waterproof switch includes a waterproof housing 1, connecting pins, a magnetic iron block 2, and a magnetic ball 3. The waterproof housing 1 is used to isolate external moisture and protect the safety of internal components. The connecting pins are used to connect the product power supply. The magnetic ball 3 is arranged inside the waterproof housing 1, and the magnetic iron block 2 is arranged outside the waterproof housing 1. The magnetic iron block 2 is used to control the movement of the magnetic ball 3. The connecting pins include a first connecting pin 4 and a second connecting pin 5. Inside the waterproof housing 1, there are a metal sheet 6, a metal connector 7, and a metal contact 8. Both ends of the metal sheet 6 have bending parts 9. The magnetic ball 3 is rollingly connected above the metal sheet 6 and can roll flexibly under the control of the magnetic iron block 2. By setting the bending parts 9, the rolling range of the magnetic ball 3 is restricted to prevent the magnetic ball 3 from rolling left and right out of the metal sheet 6. The metal connector 7 is rotationally connected to the metal sheet 6 so that the metal sheet 6 can rotate left and right with the metal connector 7 as the axis. Under the push of the magnetic ball 3, the position can be adjusted flexibly. At the same time, the bottom end of the metal connector 7 is electrically connected to the second connecting pin 5, and the metal contact 8 is electrically connected to the first connecting pin 4, providing a path for the on and off of the current. Specifically, first connect the connecting pins to the product power supply, and place the magnetic iron block 2 outside the waterproof housing 1, opposite to the magnetic ball 3 inside the waterproof housing 1. By using magnetism, the magnetic iron block 2 controls the rolling of the magnetic ball 3. The rolling of the magnetic ball 3 will push the metal sheet 6 to tilt to one side. When the bending part 9 of the metal sheet 6 abuts against the metal contact 8, a closed circuit loop is formed among the first connecting pin 4, the metal connector 7, the metal sheet 6, the metal contact 8, and the second connecting pin 5, and the current can flow, achieving the purpose of turning on the switch. When the acting force of the magnetic iron block 2 changes direction and the magnetic ball 3 rolls to the other side, the metal sheet 6 will tilt in the opposite direction, and the bending part 9 of the metal sheet 6 will separate from the metal contact 8, cutting off the circuit loop, and the current cannot flow, achieving the purpose of turning off the switch. The magnetically controlled waterproof switch of the present utility model realizes precise control of the on and off of the circuit through the control of the magnetic ball 3 by the magnetic iron block 2, and at the same time adopts a waterproof design to ensure stable operation under different environmental conditions such as humidity.

[0022] In an embodiment of the present utility model, the lower side surface of the bending part 9 of the metal sheet 6 has a convex block 10, and the convex block 10 is arranged opposite to the metal contact 8. When the magnetic ball 3 rolls, the metal sheet 6 will tilt accordingly. When the convex block 10 contacts the metal contact 8, a closed circuit loop will be formed among the metal connector 7, the metal sheet 6, the metal contact 8 in the waterproof housing 1, the first connecting pin 4, and the second connecting pin 5, that is, the switch is turned on.

[0023] In an embodiment of the present utility model, the waterproof housing 1 includes a waterproof cover 11. When a fault occurs in the switch or maintenance is required, each component inside the waterproof housing 1 can be inspected by removing the waterproof cover 11 without complex disassembly steps. The waterproof cover 11 is located above the magnetic ball 3, and the magnetic iron block 2 is located above the waterproof cover 11 to ensure that the magnetic iron block 2 can effectively control the magnetic ball 3.

[0024] In an embodiment of the present utility model, the inner wall of the waterproof cover 11 has an arc-shaped groove 12, which is adapted to the magnetic ball 3. The magnetic ball 3 is connected to the arc-shaped groove 12 in a rolling manner. The groove length of the arc-shaped groove 12 is not less than the length of the metal sheet 6 to ensure that the magnetic ball 3 can roll linearly along the arc-shaped groove 12, effectively enhancing the stability during the rolling process.

[0025] In an embodiment of the present utility model, both ends of the waterproof housing 1 have lugs 13, and fixing holes 14 are provided on the lugs 13. The fixing holes 14 are used to fix the waterproof housing 1 on the product, and thus fix the waterproof switch. The position and method of the fixing holes 14 can be set according to the actual use scenario and requirements to meet the diverse needs of different users.

[0026] The above embodiments only illustrate the implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
