The utility model is composed of a temperature sensing driving component fixed on an insulating base and a power supply control component, wherein, a temperature sensing element in the temperature sensing driving component is composed of shape memory alloys, the extending action controls the turnover of an instantaneous acting piece in the power supply control component under the action temperature, the power supply is cut, and thereby, the protecting purpose can be achieved. The utility model can be integrated with a heating tube and a power plug, the operation is convenient, and the control is reliable. The utility model provides the reliable technical means for the liquid electric heating device, so that the liquid electric heating device can come up to the stander.
Description
The utility model relates to a kind of overheated safety guard of liquid electric heater, relates to particularly that to adopt the marmem with memory function be the above-mentioned protective device of temperature-sensing element.
Existing liquid electric heater tool, as insulating pot, electric heater etc., the liquid that is heated in container reduces or dryouies, thereby when making electric heating tube be in the abnormal work situation, tend to cause the damage of utensil, even produce the accident that jeopardizes environment and human body safety.Therefore no matter be the strictness of requirement international standard or national standard all have to(for) the abnormal operating state of utensil.Existing utensil or unprotect device or adopt bimetal leaf to make temperature-sensing element, but the same device response speed of bimetal leaf temperature-sensing element is slow, movement range is little, stability, uniformity are poor, the packaging technology complexity.
The purpose of this utility model is that a kind of marmem that adopts of proposition is the overheated safety guard that temperature is subjected to the liquid electric heater tool of moved power element; because the marmem response speed is fast; good stability; high conformity; movement range and great efforts; packaging technology is also simpler, and the technological approaches preferably that provides up to standard of utensil is provided.
The utility model is design like this.Described safety guard is formed by moving assembly of propagated sensation and power-supply control unit two parts by temperature, this two partial fixing is on an insulating base frame.
It is that temperature when utensil surpasses normal value and when reaching a certain unsafe temperature that temperature is subjected to the effect of the moving assembly of propagated sensation, temperature-sensing element refresh memory and obviously elongation and this signal output made the power supply disconnection, thus play a protective role.It comprises heat conduction cover 5, places the temperature detecting element 2 of heat conduction cover 5, top rod 4 and adjusting nut 3.Heat conduction cover 5 adopts thin metallic tubd to make, and endcapped is a blind hole.The temperature detecting element adopts the marmem that still is in the Application and Development stage at present both at home and abroad, makes certain shape and also forms through " training ".Top rod 4 is used for transmitting the elongation action that is produced when temperature-sensing element recovers " memory ", and the relative position between top rod 4 and the temperature-sensing element 2 is regulated by adjusting nut 3.
Power-supply control unit comprises the wink moving plate 10 that is fixed on that the elastomeric material on the pedestal 17 makes, center stalklet 6, fixed contact 14 and SR 13.Described center stalklet 6 is aimed at the outstanding 10d of ligule on the wink moving plate, passes to the wink moving plate with the motion that will push up rod 4, makes it upset.The effect of this assembly is to come deenergization with the action that temperature-sensing element is exported, thereby utensil is played a protective role, and after fault is got rid of, can manually reset again and rework simultaneously.
Response speed of the present utility model is fast, movement range and great efforts, and high conformity, technology is simple.Guarantee the safety of liquid electric heater tool, had bigger social benefit and economic benefit.
Be further elaborated below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structure chart according to the protective device that the utility model proposes;
Fig. 2 is a wink moving plate schematic diagram.
Wherein: 1. electrothermal tube; 2. marmem spring; 3. adjusting nut; 4. the top is excellent; 5. heat conduction cover; 6. center stalklet; 7. earth stud; 8. grounding nut; 9. flange cover; Wink moving plate; 10a wink moving plate seat; 10b. fixing hole; 10c. movable contact; 10d. ligule is outstanding; 10e. Ω projection; 11. grounding pin; 12. one of power pin; 13. SR; 13a. guide tang; 13b. clubfoot; 14. fixed contact; 15. big nut; 16. container; 17. pedestal.
Present embodiment is one to be used for the protective device of insulating pot, and protective device and electrothermal tube and attaching plug are designed to one, use very convenient.The end of heat conduction cover 5 is made blind hole, and folder is welded between the two parallel exit tube walls of electrothermal tube 1, two pipe ends of the other end and electrothermal tube and flange overlap 9 be tightly connected in aggregates.Pedestal 17 places flange cover 9.Be processed with screw thread on the outer ring of flange cover, can with a big nut 15 whole device be fixed on the container 16 easily.Marmem spring 2, adjusting nut 3, top rod 4 places heat conduction cover 5 successively, constitutes temperature and is subjected to propagated sensation to move assembly.
Marmem spring is that the temperature that adopts copper base, iron-based or Nitinol to have " memory " function after special process is smelted and trained is subjected to move the power element, when temperature just often, the heat of electrothermal tube is absorbed by liquid, temperature is lower than the operating temperature that marmem spring is set, attonity output.In case liquid reduces or dryouies in the container 16, the temperature of electrothermal tube sharply rises, the very fast recovery of marmem spring " memory " of 5 afterbodys is overlapped in heat conduction---and elongation also promotes adjusting nut 3, top rod 4, be delivered to actuating signal in the power-supply control unit fast, push wink moving plate 10, cut off the electricity supply.
Power-supply control unit comprises pedestal 17, wink moving plate 10, center stalklet 6, fixed contact 14 is with SR 13.Wink moving plate 10 be an elasticity make be similar to leg-of-mutton thin slice and bar 10a forms, except that leaving the hollow out of the outstanding 10d of a ligule, leg-of-mutton base bends to the protruding 10e of Ω shape, and links to each other with bar 10a in the middle of the triangle.The place's riveting of triangle drift angle has movable contact 10c, whole wink moving plate be fixed on the leading-out terminal of electrothermal tube by the hole 10b on the bar 10a.Center stalklet 6 is aimed at two sides that the ligule on the wink moving plate is given prominence to 10d respectively with the clubfoot 13b of SR 13.When ligule when outstanding of center stalklet from moving plate of moving wink of a thruster, wink moving plate moving upset of wink takes place, the movable contact 10c on the sheet flashes with fixed contact 14 on being fixed on pedestal and separates, and cuts off the electricity supply.After fault was eliminated, when pressing button 13, the guide tang 13a on the button moved along the pilot hole on the pedestal 17, made the clubfoot 13b on the button outstanding from opposite side promotion ligule, and moving plate generation wink in wink is moved and resets, and movable contact contacts with fixed contact, connects power supply.
The outside of pedestal 17 is a plug special, 12 electric connections an of power pin of one of two leading-out terminals of electrothermal tube 1 and plug, the electric connection of another power pin (not marking among the figure) of fixed contact 14 and plug, earth stud 7 is welded on the flange cover 9, and with 11 electric connections of grounding leg of plug.
