Description
Technical field
Cooking apparatus field is the utility model is related to, more specifically, is related to a kind of pot cover component, and there is the pot cover group
The pressure cooking appliance of part.
Background technology
After pressure cooking appliance has cooked food, if pot inner pressure exceedes safe range, when uncapping, the height of ejection in pot
Injury can be produced to user by warming steam.Whether it is reduced in this safe range for pressure in detection pot, pressure cooking device
Tool can install a float-controlled valve in upper cover part, after valve element is jacked up by pressure in pot, that is, represent hypertonia in product,
Product is unable to safe opening.On the contrary, when valve element is in non-jack-up state, that is, represent that pressure has been lowered to safe model in pot
Enclose, now product can safe opening.
Old product design is designed with air-core inductance above the valve element of float-controlled valve, and valve element upper end has one section and led
Magnetic material bodies, valve element are jacked up by pot inner pressure, permeability magnetic material body insertion air-core inductance center, make air-core inductance inductance
The change of inductance value is converted into electric signal by amount increase, detection circuit, and product carries further according to the electric signal output photoelectricity or sound
Awake user can not open pot cover；Pot inner pressure drops in safe range, and valve element lands automatically, and permeability magnetic material body departs from hollow electricity
Feel hub of a spool, air-core inductance inductance value is reduced, and detection circuit converts a signal into electric signal, and defeated according to the electric signal
Pot cover can be opened safely by going out photoelectricity or sound prompting user.
In this scheme, when valve element is not jacked up, air-core inductance is above valve element, when valve element is jacked up, float top
Portion is just extend into inside air-core inductance.Because air-core inductance must be designed with certain altitude, and inductance coil must pacify
Inside pot cover, so pot cover thickness needs to be designed to larger in this scheme, cause small product size excessive, so can not only increase
Add product material cost, and influence product appearance.And the length of valve element can not design long (if valve element mistake in float-controlled valve
It is long, valve element preponderance can be caused, occur so that pot inner pressure exceeds the problem of safe range valve element can not still be jacked up, influence
Product safety performance), so after valve element is jacked up in this scheme, the top of valve element can not stretch out pot cover, and user can not directly see
To valve element, if the photoelectricity of product, sound prompting break down, user can not then judge that valve element is no and be in by jack-up state, also
It can not judge to uncap under product current state whether safely, so old scheme has larger room for improvement.
Utility model content
The utility model aims to solve the problem that at least one technical problem present in prior art.
Therefore, a purpose of the present utility model is, there is provided a kind of cost is low and the pot cover group of uncapping safe
