Detailed description of the invention
Embodiment 1:
Water dispenser liquid gravity power control apparatus, including microswitch 1, seesaw 2, outer magnetic piece 3, interior magnetic piece 4, flexible member 5 and cylinder 6.
Seesaw 2 one end is movably arranged on the body 11 of microswitch 1, and the other end is free end, and the contact 12 of microswitch 1 is positioned at the lower end of seesaw 2, seesaw 2 by lift or pressure makes contact 12 disconnect switching between Guan Bi down.Outer magnetic piece 3 is fixed on the free end of seesaw 2 and relative with magnetic pole with interior magnetic piece 4.Interior magnetic piece 4 is movably arranged in cylinder 6, and cylinder 6 inner chamber is divided into mutual disconnected chamber A61 and chamber B62 by it.Cylinder 6 is externally provided with the inlet 63 being communicated to chamber A61.When interior magnetic piece 4 moves along the outside magnetic piece 3 of cylinder 6 inwall, the magnetic force between itself and outer magnetic piece 3 is incremented by.Flexible member 5 is arranged in the B62 of chamber, and it is compressed along with the movement of interior magnetic piece 4 or loosen.Microswitch 1 is positioned at outside cylinder 6 and is relatively fixed with cylinder 6, is relatively fixed and refers to that microswitch 1 and cylinder are each attached on housing 10.
The contact 12 i.e. on & off switch of microswitch of microswitch 1, it has disconnection and Guan Bi two states.
Preferably, it is provided with sealing ring 7 between interior magnetic piece 4 and cylinder 6 inwall.
Preferably, flexible member 5 is spring.
Preferably, interior magnetic piece 4 is positioned on the end face of B62 side, chamber and is connected to boss C8, is provided with the boss D9 corresponding with boss C8 position in the B62 of chamber, and spring one end is arranged on boss C8, and the other end is arranged on boss D9.
Sketch present invention installation on water dispenser and operation principle: as it is shown on figure 3, heating cabinet 101 lower end of water dispenser is provided with water inlet 102 and cylinder connector 103, heating cabinet 101 sidewall is provided with the outlet 104 of valve, in heating cabinet 101, is provided with electric heater 105.
As it is shown on figure 3, the inlet 63 of cylinder 6 is connected on the cylinder connector 103 of heating cabinet 101 by joint, and cylinder 6 is in vertical state.
Along with liquid level lifting in heating cabinet 101, the gravity of the water that interior magnetic piece 4 is subject to is gradually increased, the gravity of water finally overcomes the elastic force of flexible member 5, interior magnetic piece 4 is made to move down in cylinder 6, then inside and outside magnetic piece is apart from close, and the repulsion between inside and outside magnetic piece increases therewith, and seesaw is pressed for 2 times by final outer magnetic piece 3 under repulsion effect, the contact 12 of microswitch 1 is switched to connected state, and electric heater 103 is energized.
