Detailed description of the invention
Embodiment 1:
As shown in Figure 1, 2, the water-shortage protection device of water dispenser, 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.
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 liquid outlet 64 and is communicated to the inlet 63 of chamber A61.When interior magnetic piece 4 moves along cylinder 6 inwall to the direction near outer magnetic piece 3, the magnetic force between itself and outer magnetic piece 3 is incremented by.When interior magnetic piece 4 move to the magnetic force between itself and outer magnetic piece 3 maximum time, the liquid outlet 64 of cylinder 6 is communicated to chamber A61.
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.When interior magnetic piece 4 moves along cylinder 6 inwall to the direction near outer magnetic piece 3, flexible member 5 is gradually compressed.
Microswitch 1 is positioned at outside cylinder 6 and is relatively fixed with cylinder 6, and microswitch and cylinder are each attached on housing 10, are and are relatively fixed.
The contact of microswitch and the switch of microswitch, 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 flexible member 5 one end is arranged on boss C8, and the other end is arranged on boss D9.
In the present embodiment, cylinder 6, boss C8 and boss D9 are working of plastics.
Sketch present invention installation on water dispenser and operation principle: as shown in Figure 3, the water side of water inlet pipe 101 connects with the inlet 63 of cylinder 6, the liquid outlet 64 of cylinder 6 is communicated to heating cabinet 103 by drain pipe 102, microswitch 1 electrically connects with the electric heater 104 in heating cabinet, for controlling power-off or the energising of electric heater 104.
When water inlet pipe 101 having water and hydraulic pressure reach predetermined value, water passes into the chamber A61 of cylinder 6 by water inlet pipe 101, the hydraulic pressure that interior magnetic piece 4 is subject to is more than the elastic force of flexible member 5, interior magnetic piece 4 moves to the direction near outer magnetic piece 3, repulsion between inside and outside magnetic piece is gradually increased, seesaw is pressed for 2 times by outer magnetic piece 3 under repulsion effect, and the contact 12 of microswitch 1 is switched to closure state (as shown in Figure 2), and electric heater 104 is energized.Meanwhile, in the process that interior magnetic piece 4 moves to the direction near outer magnetic piece 3, chamber A61 volume is gradually increased, and the liquid outlet 64 of cylinder 6 is communicated to chamber A61, and the aquiform stool in such chamber A61 can be passed through liquid outlet 64 and be discharged in the heating cabinet 103 of water dispenser.
In water inlet pipe 101 anhydrous or when hydraulic pressure is not enough, interior magnetic piece 4 does not move or moves on a small quantity, distant between inside and outside magnetic piece, and repulsion between the two is not enough to press seesaw for 2 times, the contact of microswitch 1 also keeps initial off-state, and electric heater 104 is in power-off.
