Description
Technical field
This utility model is related to heater circuit field, and in particular to a kind of heater circuit gating switch.
Background technology
In real life, the design for being related to heater circuit all has a demand for manually selecting heating power, such as electric blanket,
Space heater etc. is both provided with temperature-adjusting device, and temperature adjustment essence is exactly the regulation to heating power, different to produce
Heat.
The mode of power selection realized by switch common at present, substantially has push button to adjust and knob regulation, existing
The defect for adjusting switch is that switching knob shift in position or button are pressed because of maloperation sometimes, bring to user
Trouble.If user does not find that switch is misused, and have selected the high gear of heating power, when causing high-temperature heating in time
Between long, potential safety hazard just occurs.
Utility model content
The purpose of this utility model is to provide a kind of heater circuit gating switch, simple to operate, it is to avoid maloperation, prevents
Potential safety hazard.
For reaching above-mentioned purpose, base case of the present utility model is as follows：
Heater circuit gating switch, including switch knob, heater circuit, shell and sleeve, the heater circuit and sleeve
The inside the shell is encapsulated in, and the switch knob upper surface is provided with graduation mark, and rotating shaft, institute is fixed with below the switch knob
State shell and be provided with the through hole passed through for rotating shaft, at the switch knob lower surface, be provided with conducting block, the conducting block and quarter
The position of degree line is corresponding, and the rotating shaft is socketed in sleeve, and the surface circle of the rotating shaft is wound with extension spring, the two ends point of the extension spring
It is not fixed on the switch knob and the sleeve, the upper end of the sleeve is fixed with three collets, and the collets are equal
Two conductive copper wires are covered with, two conductive copper wires are connected with the heater circuit, the width of the conducting block and institute
The spacing that states between two conductive copper wires is identical.
The operation principle of this utility model base case：When adjusting heating power, the conducting block is located at three
Between one of gap of individual collets, by observing the graduation mark, user can understand conducting block place at any time
Position, now, extension spring produces inside pulling force all the time, because sleeve is fixed, switch knob is because the elastic force of extension spring is acted on
It is subject to downward pulling force；When needing to adjust heating power, first pulling up switch knob makes which overcome the pulling force of extension spring to move upwards
Dynamic so that the conducting block leaves the gap between collets, then rotating switch handle, makes conducting block move into one
Between two conductive copper wires of collets, corresponding heater circuit is connected, the regulation of heating power is realized, now, described
Conducting block produces inside pulling force because extension spring will recover elastic force deformation so that the conducting block on switch knob is stuck in institute
State between two conductive copper wires；Because the rotation of switch knob could be rotated after needing to pull up, it is not in imprudence
Encounter switch knob and maloperation occurs, prevent potential safety hazard.
Preferred version one：Based on scheme preferred version, be provided with three on the outer surface of outer cover around the through hole
Individual regulation identifies, and the position of the regulation mark and the collets corresponds so that people can be according to the accurate tune of mark
The different power of section.
Preferred version two：Preferably one preferred version, the switch knob are knob switch, make regulation work(
Rate simple to operation and more accurate,.
Preferred version three：Preferably two preferred version, the switch knob are made up of insulant, anti-leak-stopping
Electricity, it is ensured that the safety of user.
