The pumping motor is connected (for the prior art, not to be described in detail), the body 7 is provided with a chamber 74 inside, and a weight 73 is provided in the chamber 74, the weight 73 is a sphere, and the chamber 74 is divided into a first A space 75 and a second space 76, the first space 75 is equipped with a micro switch 77, the micro switch 77 is electrically connected with the electric wire 71, and the micro switch 77 is provided with a reed inside, and The micro switch 77 is linked with a push piece 78 . The pushing member 78 is pressed by the weight 73 rolling in the two spaces to control the opening and closing of the micro switch 77 .

When the pool is full of water, the main body 7 floats in a nearly upright shape, so that the weight 73 rolls to the first space 75 to press the pusher 78 to move, so that the micro switch 77 is turned off, and then the pumping motor stops. If the water level drops, the main body 7 becomes nearly upside down, so that the weight 73 rolls to the second space 76 under the influence of gravity, so the micro switch 77 is bounced off by the action of the reed, and then the micro switch is turned on. 77 to make the water pumping motor operation water supply by switching on the power supply.

Because the weight 73 utilizes the design of the sphere and its own weight to roll back and forth to suppress or release the microswitch 77, so it is an unstable state between the weight 73 and the microswitch 77, especially the The micro switch 77 is provided with a reed, if the weight 73 does not really suppress the pusher 78, the micro switch 77 will jump off. Therefore, once the water level rises and falls too fast, or when the water level fluctuates due to external force, the body 7 will sway, and the weight 73 will not be able to press the pusher 78 of the micro switch 77, resulting in the micro switch 77 repeated opening and closing. In this way, not only the waste of electric power is caused, but also the service life of the micro switch 77 and the pumping motor is reduced, and the water level control is unstable.

Please refer to Fig. 1 to Fig. 3, shown in the figure is the selected embodiment structure of the utility model.

This embodiment includes a hollow body 1, the body 1 is divided into an air chamber 12 and an accommodating chamber 13 by a partition plate 11 inside, the air chamber 12 is provided with a compartment 121, and a compartment 121 is slidingly provided with a The weight 2 , in this embodiment, the weight 2 is a cylinder to facilitate sliding in the compartment 121 . And this accommodating chamber 13 is provided with a switch 4, and this switch 4 is connected with an electric wire 5, and this electric wire 5 one end passes through this body 1 and is fixed in a fixed position and then is connected with pumping motor, and this heavy hammer 2 is with a movable The opening and closing of the switch 4 is linked by the rod 3 .

One end of the above-mentioned movable rod 3 is fixedly connected with the weight 2, and the other end penetrates the partition plate 11 and extends into the switch 4. In this embodiment, the movable rod 3 includes a first movable part 31 and a first movable part 31 which are pivotally connected to each other. A second movable part 32, and the weight 2 is fixedly connected to one end of the first movable part 31 opposite to the pivot connection, and one end of the second movable part 32 to the relative pivot connection extends into the switch 4, and a The first stopper 321 and a second stopper 322 form an interval 323 between the first stopper 321 and the second stopper 322, and the second stopper 322 can prevent the second movable part 32 from breaking away from the switch 4.

The above-mentioned switch 4 is provided with a first contact pin 42, a second contact pin 43 and a third contact pin 44 for electrically connecting with the electric wire 5, and the end of the first contact pin 42 opposite to the electric wire 5 has a pivot The contact point 421 is used for pivotally connecting the middle section of a rocker arm 41 . One end of the rocker arm 41 is provided with a first electrical contact 411, and the other end extends into the interval 323 formed between the first block 321 and the second block 322 of the movable rod 3, and is sleeved with an elastic component 45. one end. The other end of the elastic component 45 is embedded in the groove 46 of the inner wall of the switch 4, so that the rocker arm 41 is located in the section 323 and is sleeved with one end of the elastic component 45 to form a movable joint 412, and the space in the section 323 greater than the width of the joint 412 . The second contact pin 43 has a second electrical contact 431 opposite to the end connected to the electric wire 5, and the second electrical contact 431 is on the side corresponding to the first electrical contact 411 of the rocker arm 41, and is supplied to the first electrical contact 411. An electric contact 411 contacts to form a loop. And the third contact pin 44 has a third electrical contact 441 opposite to the end connected to the electric wire 5, and the third electrical contact 441 is corresponding to the first electrical contact 411 of the rocker 41 opposite to the second electrical contact. The other side of the contact 431 is in contact with the first electrical contact 411 to form another loop.

Thereby, when the utility model is used for water supply, its electric wire connects the first contact pin 42 and the second contact pin 43 of this switch 4 respectively, so when the liquid level of the pool drops, as shown in Figure 2, due to connecting the One end of the electric wire 5 of the main body 1 is fixed so that the main body 1 is in an upside-down shape, and the weight 2 is guided by the compartment 121 to move away from the partition plate 11 due to gravity, so as to move the moving rod 3 in conjunction with the displacement, and The first block 321 pushes the joint 412 where the rocker arm 41 is sleeved on the elastic component 45 to move. Since the middle section of the rocker arm 41 is pivotally connected to the pivot joint 421 of the first contact pin 42, the first electrical contact 411 of the rocker arm 41 moves in the opposite direction to contact the second electrical contact 431 of the second contact pin 43. A loop is formed, and the pumping motor is started to run and supply water.

And when the liquid level rises to the fixed position, as shown in Figure 3, the body 1 is upright due to the buoyancy of the air chamber 12, and the weight 2 is also guided by the space 121 to the partition plate 11 under the action of gravity. close to move the movable rod 3, the second block 322 will push the joint 412 where the rocker arm 41 is socketed on the elastic component 45 to move, so that the first electrical contact 411 of the rocker arm 41 is in the opposite direction.

Since the rocker arm 41 is located in the section 323 and is sleeved on one end of the elastic component 45 to form a movable joint 412, once the joint 412 is pushed, it will be pivoted due to the elasticity of the elastic component 45 and the middle section of the rocker arm 41. relationship, the first electrical contact 411 of the rocker arm 41 is positioned in contact with the second electrical contact 431 of the second contact pin 43 or the third electrical contact 441 of the third contact pin 44 until the movable rod 3 Push the joint 412 again to make the rocker 41 move. Because the space of the section 323 is greater than the width of the joint 412, a margin is reserved between the two, so when the main body 1 is subject to water fluctuations and the movement of the weight 2 is smaller than the reserved margin, the movable The rod 3 does not affect the change of the joint 412, so that the first electrical contact 411 of the rocker arm 41 is still in good position to contact the second electrical contact 431 of the second contact pin 43 or the second electrical contact 431 of the third contact pin 44. The three-electric contact 441 prevents the pumping motor from being turned on and off sometimes.

Furthermore, when the weight 2 is vibrated from the water surface, the movement of the rocker arm 4 can be reduced by the pivot connection between the first movable part 31 and the second movable part 32, and the rocker arm 4 can be reduced. The joint 412 of the arm 4 leaves a certain margin in the section 323 formed by the first block 321 and the second block 322, so that the movement of the movable rod 3 to the rocker 4 can be buffered, so that the movement of the movable rod 3 to the rocker arm 4 will not be caused by the Repeated contact between the first electrical contact 411 of the rocker arm 41 and the second electrical contact 431 of the second contact pin 43 or the third electrical contact 441 of the third contact pin 44 causes repeated opening and closing of the circuit, and The utility model makes the power control more effective in implementation and greatly reduces unnecessary power waste and equipment renewal.
