The dumping protective switch has the beneficial effects that: the dumping protective switch can meet the needs of all-around dumping protection of household appliances, the switch has simple structure, small volume and low manufacturing cost; in addition, as the conductor of the switch is sealed in the shell wholly, short circuit can not happen under the water condition, so as to realize reliable safety protection.
Description
Technical field
The conduction that the utility model relates between two current-carrying parts directly contact connects, and particularly relates to rolling element and exerts pressure and finish the Protection switch of toppling over that electrically contacts.
Background technology
Household electrical appliance, especially the inner household electrical appliances that water tank or heat generating member are housed, when toppling over like accident as air cooler, humidifier, electric heater, the as easy as rolling off a log electric shock, stop up the high temperature air outlet, damage electrical equipment even fire incident, thus these type of household electrical appliance must dumping switch be installed in inside, in case such household electrical appliances accident is toppled over, just cut off electricity immediately automatically and quit work, prevent that contingency from taking place.
For realizing this purpose, the prior art dumping switch has multiple patterns such as pendulum, roller, ball-type.Pendulum can only be swung in single plane around plane hinge because of pendulum, therefore can only be implemented in the protection of toppling in this plane; Equally, the roller of roller also can only roll in single plane, also can only be implemented in the protection of toppling over of single plane; Yet the ball of ball-type but can roll in any direction, satisfy the comprehensive protection of toppling over of household electrical appliances, be 200410047123.7 and be called the patent of invention of " mechanical type dumping switch " as application number, comprise that housing, sensitive switch, heavy ball (ball), connecting rod, support bar constitute, it can comprehensively move, but structure is complicated, and volume is also big, cost is higher, adopts the household electrical appliance of this switch will cut down the market competitiveness on price.In addition, sensitive switch is difficult to sealing, and dress is toppled over back water with its electrical equipment and may be entered in the switch, causes short circuit or electric shock accidents.
Summary of the invention
The technical problems to be solved in the utility model be to avoid above-mentioned the deficiencies in the prior art part and design a kind ofly topple over Protection switch, this volume of switch is little, cost is low, good seal performance, can effectively prevent to use under the situation of water and the phenomenon that is short-circuited.
The utility model is to solve the problems of the technologies described above the technical scheme that proposes to be, a kind ofly topple over Protection switch, comprise housing and spin, described housing comprises epicoele and cavity of resorption again, there is opening in the laminate central authorities of especially separating described epicoele and cavity of resorption, the up big and down small infundibulate that is of this opening; Described spin freely is placed on the top of laminate; Be equipped with in the cavity of resorption below opening and comprise the upper and lower conductive reed that has a pair of electrical pickoff at least, described upper and lower conductive reed root is fixed in the sidewall of the nearly bottom surface of housing, draws the housing place in circuit with insulated electric conductor.
When described housing of toppling over Protection switch was in the normal position of level, described ball fell into the opening of described laminate just, will go up conductive reed and press to down conductive reed, made that the electrical pickoff on the upper and lower conductive reed contacts with each other, thereby connected circuit; Otherwise when described housing tilted, described ball was rolled to the lower side in position along the inclined-plane of the opening of laminate, and upper and lower conductive reed is returned to free state, and electrical pickoff separates, thereby cut off circuit.
The diameter of described ball is greater than the diameter of the maximum disc of described laminate opening; Described ball comprises steel ball, copper pearl, lead sweat, alloy pearl, glass marble or Ceramic Balls; Described ball is as additive and the resin balls of mold pressing form or injection molded with silica flour.
The funnel inner face upper angled face of described laminate opening is milder, and ball can freely roll thereon.
Described inboard of going up conductive reed has elastomeric steel disc to assist, to improve antifatigue and the anti-yield limit that goes up conductive reed; Upper and lower conductive reed material comprises copper alloy; Electrical pickoff is copper alloy or silver.
Compare with prior art, the beneficial effects of the utility model are: can satisfy the omnibearing needs of toppling over protection of household electrical appliance, construction of switch is simple, and volume is little, low cost of manufacture.In addition, because the electric conductor of switch all is sealed in the housing,, realized reliable safeguard protection even also can not be short-circuited having to use under the situation of water.
Description of drawings
Fig. 1 is that the utility model is toppled over the cross-sectional schematic that Protection switch is in normal operating conditions;
Fig. 2 is the cross-sectional schematic that described Protection switch is in heeling condition;
Embodiment
