Abstract
The utility model provides a safety switch which comprises a switch pedestal, a general switch and an external switch button, wherein a humidity detection device arranged in the switch pedestal comprises a humidity detector and a control module and is connected with a general power switch. The humidity detector detects whether the humidity in the switch pedestal exceeds the preset value, and the control module powers off the switch. The edge of the switch pedestal is provided with a sealing ring, and the switch button is provided with a seal cover, which improve the sealing performance and prevent the interior of the switch is wetted. Compared with a common switch, the safety switch is improved in moisture resistance. When the humidity is high, the power is off automatically, thereby improving the safety performance of using the switch.
Description
Technical field
The utility model belongs to the field of switching function expansion, relates in particular to a kind of safety switch.
Background technology
Switch refers to that one can make open circuit, makes current interruptions or make it flow to the electronic component of other circuit.Switch is one of indispensable element of household electric, and most switch is owing to being hand switch.Under normal circumstances, switch usage safety performance is relatively good, if but at moist environment, or for children, regular tap is used still potential certain risk.According to statistics, it is relevant with moist harm that the whole world has more than 1/4 industry manufacture defective products every year.Switch humidity resistance is low, not only can affect the electronic product life-span, the most important electric shock accidents that easily meets accident, and therefore how making the humidity resistance of switch be guaranteed to be one is worth the problem solving.
Summary of the invention
The utility model, in order to solve the problem that produces potential safety hazard after switch makes moist, provides a kind of safety switch.Comprise switch pedestal, master switch, external switch button, switch pedestal inside has humidity detector, and humidity detector is comprised of moisture detector and control module, and humidity detector connects battery main switch; Moisture detector detects switch pedestal interior humidity and surpasses 80%, and control module is cut off Switching Power Supply.
The switch pedestal edge of safety switch has sealing ring.When switch is installed, with metope or other contact-making surfaces, have gap to a certain extent, switch environment is humidity too, still easily makes moist for a long time.The sealing ring at dimension switch pedestal edge, stops gap after can guaranteeing to install and produces, and improves inner degree of drying.
Further technological improvement of the present utility model is: the shift knob of safety switch, and for insulation material is made.Shift knob has sealing shroud, and shift knob and switch pedestal installation connect into whole, also exist certain gap, easily invade moisture, therefore in order being that switch forms relative sealing state, on shift knob, to there is sealing shroud, can to improve the sealing property of switch integral body.
The utility model is obtained following technique effect:
Compared with prior art, the utility model is by carrying out technological improvement to regular tap, cost increases not obvious, from protection against the tide and inner two designs of damp auto-breaking of crossing of switch, can effectively prevent that Household appliance switch from undermining the note potential safety hazard that further elimination produces because of electric leakage because humidity causes electrical equipment.
Accompanying drawing explanation
Fig. 1 is the side perspective schematic diagram of a kind of safety switch of the utility model.
Embodiment
For the ease of those of ordinary skills, understand and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
Embodiment
As shown in Figure 1, the utility model discloses a kind of design of safety switch.Comprise switch pedestal 1, master switch 2, external switch button 3.Switch pedestal integral body is square, and long with wide identical with standard household switch, whole material is plastic material.Switch pedestal edge has sealing ring 4, and while installing with mounting plane, sealing ring 4 can at utmost reduce gap between the two; For switch is whole, form relative sealing state, its outside shift knob 3 has sealing shroud 5, improves overall sealing performance.Switch pedestal 1 inside has humidity detector 6, and humidity detector 6 is comprised of moisture detector 7 and control module 8, and humidity detector 6 connects battery main switch 2.When moisture detector 6 detects switch pedestal 1 interior humidity, surpass 80%, control module 8 receives this information, and control module 8 is sent instruction and cut off master switch 2 power supplys, and 3, external switch button cannot act on.When switch pedestal 1 interior humidity value is lower than 80%, control module 8 is automatically sent instruction and is recovered master switch 2 energisings, can use.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
