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, the contact of microswitch 1
12 lower ends being positioned at seesaw 2, seesaw 2 by lift or pressure makes contact 12 switch between Guan Bi disconnecting 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 along cylinder 6 inwall to close
When the direction of outer magnetic piece 3 is moved, the magnetic force between itself and outer magnetic piece 3 is incremented by.When interior magnetic piece 4 moves between itself and outer magnetic piece 3
Magnetic force 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 edge
When cylinder 6 inwall moves 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,
It is and is relatively fixed.
The contact of the microswitch i.e. 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 connection boss C8, is provided with and boss C8 position in the B62 of chamber
Corresponding boss D9, 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.
Summary this utility model installation on water dispenser and operation principle: as it is shown on figure 3, the water side of water inlet pipe 101
Connecting with the inlet 63 of cylinder 6, the liquid outlet of cylinder 6 64 is communicated to heating cabinet 103 by drain pipe 102, microswitch 1 with
Electric heater 104 in heating cabinet electrically connects, for controlling power-off or the energising of electric heater 104.
In the case of having water and hydraulic pressure to reach predetermined value in water inlet pipe 101, water is passed through the chamber of cylinder 6 by water inlet pipe 101
A61, the hydraulic pressure that interior magnetic piece 4 is subject to is more than the elastic force of flexible member 5, and interior magnetic piece 4 moves to the direction near outer magnetic piece 3, inside and outside
Repulsion between magnetic piece is gradually increased, and seesaw is pressed for 2 times under repulsion effect by outer magnetic piece 3, and the contact 12 of microswitch 1 is switched
To closure state (as shown in Figure 2), electric heater 104 is energized.Meanwhile, the mistake moved to the direction near outer magnetic piece 3 at interior magnetic piece 4
Cheng Zhong, 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 by going out liquid
Mouth 64 is discharged in the heating cabinet 103 of water dispenser.
In the case of in water inlet pipe 101, anhydrous or hydraulic pressure is not enough, interior magnetic piece 4 does not moves or moves on a small quantity, inside and outside magnetic piece it
Between distant, repulsion between the two is not enough to press seesaw for 2 times, and the contact of microswitch 1 also keeps initial disconnection
State, electric heater 104 is in power-off.
