The specific embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As Fig. 1, Fig. 2, shown in Figure 4, automatically outage safty of drinking water machine comprises water dispenser body 1, bucket 3, be provided with heater circuit in the water dispenser body, water dispenser body upper end is provided with pressure switch 2, this pressure switch comprises housing 201, movable contact piece 4 alive, compression spring, the 5 fixing parts 6 that touch, case top and bucket face joint and the position of bearing bucket pressure are provided with through hole 202, and case top is provided with the bucket mouth 203 that bucket is installed.Movable contact piece alive top is insulating knockout pin 401, and the middle part is insulation limited block 402, and the bottom is conduction push rod 403.The fixing part that touches is provided with insulated spring seat 601, insulated spring seat middle part is provided with conductive contact blade 602, and the movable contact piece of living, fixing touching between the part are provided with compression spring, and compression spring one end is placed in the insulated spring seat, the other end is placed in the conduction push rod, and offsets with described insulation limited block.Said fixing is touched part and is fixed in the housing inner bottom part, and the live insulating knockout pin of movable contact piece and the through hole that case top is provided with are slidingly matched.The conductive contact blade of the conduction push rod of movable contact piece alive, fixing tactile part inserts in the loop of the inner heater circuits of water dispenser as two pins of pressure switch.Under the original state, live movable contact piece under the compression spring effect, the insulating knockout pin of the movable contact piece of living stretches out through hole, and the conduction push rod does not contact with conductive contact blade; In the time of in insulating knockout pin stretches into housing, the conduction push rod contacts with conductive contact blade.According to the said structure feature, in order to improve reliability of structure, above-mentioned compression spring adopts volute spring, and the fixing insulated spring seat that touches part arranges tapered.Simultaneously, for the ease of maintenance, replacing, pressure switch is set to split-type structural with the drinking-water body.And in order to improve the reliability of control, two groups or more movable contact piece alive, compression spring, the fixing part that touches are set in pressure switch, and are set to shown in Figure 2 being electrically connected in series between each group, can improve control accuracy, reduce maloperation.
In conjunction with said structure, the operation principle of pressure switch is further described.As shown in Figure 3, when the bucket of filling water was positioned on the pressure switch of water dispenser body upper end, end face will the live insulating knockout pin of movable contact piece in bucket water side was pressed in the housing of pressure switch.At this moment, compression spring is compressed, and the conduction push rod of the movable contact piece of living offsets with the fixing conductive contact blade that touches part, i.e. the heating circuit that conducting conduction push rod, conductive contact blade connect, and can open heating this moment.When the water yield was used up in the bucket, the pressure that bucket produces the conduction push rod of the movable contact piece of living was during less than the elastic force of compression spring, and the push rod that then conducts electricity separates with conductive contact blade in the compression spring effect, and bucket is slightly upspring, and can't open heating operation this moment.Above process is the principle process of the utility model pressure switch control water dispenser heater circuit.
