The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, novel structure is provided, can improves the novel microswitch structure of action accuracy.
The technical scheme that realizes the utility model purpose is: a kind of novel microswitch structure, match with the buoy in placing water tank, it comprises the sensitive switch body and is arranged on the contact of being triggered by buoy institute externally applied forces on the sensitive switch body, it is characterized in that: also be provided with flexible strip contact on the described sensitive switch body, one end of contact is fixed on the sensitive switch, one end is a free end, and described contact is positioned at the position of the inboard and close contact stiff end of contact.
Described contact is curved along bearing of trend; The arc convex surface of contact and buoy sliding contact.
The face that contacts with contact on the described buoy is a convex globoidal.
As further improvement of the utility model, described buoy is hinged on the water tank by bearing pin.The plumb line of the axis deviation buoy of described rotating shaft, and a side at the convex globoidal place that contacts with contact on the close buoy.
In the utility model, because be provided with on the sensitive switch body that an end is fixed, end arc Contact piece freely, arc Contact piece is under the effect of buoy external force, touch the contact of sensitive switch repeatedly in the mode of lever, be different from the triggering mode that link member moves up and down in the prior art, thoroughly avoided the phenomenon of link member generation clamping stagnation in the prior art.Particularly when this sensitive switch and buoy are used, the arc convex surface of contact and the convex globoidal sliding contact of buoy, the contact that also can avoid buoy and sensitive switch in the prior art adopts that the radial type syndeton is brought because the caused clamping stagnation problem of vibrations in the long-distance transport process has further ensured the sensitive switch accuracy of action.Simultaneously; because the particularity of buoy rotating shaft position; therefore when they are applied in dehumidifier, mobile air conditioner or similar band water completely on the equipment of defencive function the time; after through long-distance transport and since for the first time when powering on water tank be empty (anhydrous), the water tank buoy under the effect of gravity down-shift of working center until spacing position to water tank; under the effect of lever force; water tank buoy jacking block compresses the contact of sensitive switch, and the circuit of electric-control system is connected thereupon, and complete machine can move.Therefore, the utility model equipment that can solve dehumidifier, mobile air conditioner or similar band water tank container from another aspect improper water of appearance that powers on for the first time after through long-distance transport is completely being protected problem.
