Abstract
The utility model relates to an alarm device for high-pressure cookers. A spring type alarm clock is arranged on the upper end of a spring of a high-pressure cooker which is provided with a spring type safety device, a piston metal sheet is arranged on the lower end and the mouth part is provided with a metal casing. The utility model can give an alarm in advance when the pressure in the cooker reaches a certain limit, and explosion accidents caused by overhigh pressure in the cooker can be prevented.
Description
The utility model relates to a kind of pressure cooker pressure warning unit.
Since pressure cooker built-in pressure ratio external pressure height, under the pressure cooker normal condition, without any danger, but when its internal pressure is excessive, the phenomenon of then can blasting.For avoiding the generation of explosion accident, now designed some safety devices, as commercially available a kind of pressure cooker, it is when pot inner pressure is excessive with the spring safeties, top spring atmospherically, opening is emitted a part of gas, to reduce the pressure in the pot.The device of many safety valves and so on is also arranged in addition, and its characteristics as above.Adopt said apparatus, can not in time get rid of, can produce explosion accident equally as crossing anticyclonic gas.
The purpose of this utility model aims to provide a kind of pressure cooker warning device, and this device can be reported to the police when the pressure cooker pot inner pressure arrives certain limit in advance, and reminds people is taked certain precautionary measures, avoids the generation of explosion accident.
The purpose of this utility model realizes in the following manner, and the pressure cooker warning device has the hole 4 of shock mount formula safeties on pot cover 1.On the hole wall of spring upper end, a Mainspring type quarter-bell 3 is housed, the lower end connect one with the sheet metal 6 of spring hole wall sealing, there is the metal shell 2 that closely links to each other with pot cover 4 walls upper end in hole.
Accompanying drawing is the utility model structural representation.
With reference to accompanying drawing, the utility model is that the pressure cooker to existing band spring safeties is improved, dress Mainspring type quarter-bell 3 on the hole wall of spring upper end.Sheet metal 6 when pot inner pressure spring lower end, top during to certain limit, on the gases at high pressure triggers quarter-bell by spring and sounds the alarm, and reminds the user to take measures on customs clearance at once, avoids a pot internal gas pressure to raise again, stops the generation of explosion accident with this.
The metal shell 2 of 4 walls upper end, hole can be fixed or revolving.When being fixed, quarter-bell clockwork spring switch is contained on the metal shell.As when being rotary, the quarter-bell clockwork spring directly links to each other with shell, and rotational shell promptly tightens clockwork spring.
The utility model is simple in structure, can be reported to the police during to certain value in the pressure cooker internal pressure, promptly takes measures, and stops pot generation of body explosion accident.
