Description
Technical field
The utility model relates to a kind of electric control switch, especially a kind ofly is used to prevent the totally enclosed type anti-dumping switch that shields when electrical equipment is toppled over.
Background technology
Be generally used for the anti-dumping switch that shields when household electrical appliance such as various warm-air driers, electric fan and electric heating installation using oil as medium and other electrical equipment are toppled over; its a kind of structure is the spring-piece type anti-dumping switch; the switching and relevant circuit turn-on at two shell fragments of switch external exposed in dependence, realizes the protection that electrical equipment is toppled over.But do not replaced by the ball-type anti-dumping switch because its job security is high.The ball-type anti-dumping switch is that a steel ball is set in housing, and going to the bottom at housing is provided with a bellmouth, and going to the bottom of bellmouth is embedded with the pair of metal contact, and when steel ball was positioned at the centre position, steel ball contacted with the metal contact, with relevant circuit turn-on.By the change in location of steel ball, with the conducting of metal contact, disconnect to realize electrical equipment toppled over and protect.And the anti-dumping switch of above-mentioned two kinds of structures, its action component is that shell fragment or steel ball and metal contact all are not arranged in the housing of sealing, action component and exterior, corrosion at gases such as the difference that is subjected to the each department air humidity and airborne acid, alkali, cause the corrosion of action component easily, make the wink of switch move decreased performance, influence dependability, and also shortened the useful life of switch.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of can maintained switch wink moving property, safe and reliable totally enclosed type anti-dumping switch.
The technical scheme that the utility model solves the problems of the technologies described above is: a kind of totally enclosed type anti-dumping switch, the housing that comprises the case formation of two connections, be arranged on sensitive switch and carriage mechanism in the housing, described housing has sealing and the bottom is upper cavity and the lower chamber and the cavity between upper cavity and lower chamber of bowl-type, spheroid is housed in the upper cavity, sensitive switch is housed in the lower chamber; Described carriage mechanism is made of pallet, compressing tablet and back-moving spring, its two sides of compressing tablet that supporting is connected in the lower chamber join with the contact of back-moving spring and sensitive switch respectively, the other end of compressing tablet is equipped with its two sides of supporting spring and joins with the contact of back-moving spring and sensitive switch respectively, the other end of compressing tablet is equipped with pallet, and pallet is arranged in the cavity, spheroid falls into and depresses pallet in the cavity, and compressing tablet is depressed the contact of sensitive switch and connected circuit.
Operation principle of the present utility model is: when main frame just often, the spheroid in the anti-dumping switch falls in the cavity and depresses pallet under action of gravity, then pallet moves down compressing tablet to depress the contact of sensitive switch, anti-dumping switch moment energized or circuit.When main frame tilted and falls, with the housing tilt displacement, then pallet was owing to the disengaging of spheroid sets back compressing tablet to the spheroid in the anti-dumping switch under the effect of its gravity, and sensitive switch moment disconnection reaches and cuts off the electricity supply or the purpose of circuit.
After the utility model is implemented technique scheme, utilized the sensitive switch of mature technology, by the variation of spheroid with the main frame position, spheroid is fallen in the cavity of housing depress pallet, or the cavity of spheroid disengaging housing makes pallet be in free state, realize controlling the switching work of sensitive switch and power supply and circuit by compressing tablet, it employs angle is comprehensive.Because housing of the present utility model is connected and composed by two cases, the lower chamber of housing is equipped with sensitive switch, and the spheroid of the action component on top, pallet and compressing tablet are arranged in the upper cavity of sealing, therefore can not be subjected to the influence of external environment factors such as the corrosion of gases such as airborne acid, alkali and air humidity again, guarantee the moving property of wink of switch motion, safe and reliable, as to improve switch useful life.Anti-dumping switch of the present utility model can be widely used in household electrical appliance and other electrical equipment such as warm-air drier, electric fan and electric heating installation using oil as medium.
