Description
Technical field
The utility model relates to the pressure cooker field, refers in particular to the pressure cooker that a kind of user of convenience carries out quick exhaust pressure relief.
Background technology
Relief valve is an important components of pressure cooker, has the function of pressure limiting and exhaust.During normal the culinary art, relief valve is in closed condition, and when inner tube of pressure cooker reached pressure limiting pressure, relief valve was wanted outside exhaust pressure relief, guarantees that pressure cooker is no more than the safe pressure of permission; In addition, because the folding of pressure cooker lid safety requirements, in interior pressure during greater than 12KPa, pot cover can not be become flexible, during greater than 4KPa, pot cover can not be opened in interior pressure, so when opening pot cover, need first pressure release,, normally the bonnet of relief valve is mentioned or rotate bonnet and make it to be in opening for quick exhaust pressure relief, steam is discharged from blast pipe, exhaust pressure relief in this way, because operator's hand will contact relief valve, operating process is scalded by steam easily.For addressing this problem, the effect that utilizes lever is arranged in the prior art, make the bonnet jack-up of an end of lever by button with relief valve, when hand leaves button, lever resets immediately, and relief valve stops exhaust, the weak point of this solution is exactly when the artificial exhaust of needs, hand must be pinned the exhaust button always and can not unclamp, and operation is trouble comparatively, as Chinese patent CN01209620.2.Also have and adopt the switch drive lever of controlling oneself, hand leaves switch lever and does not also reset, relief valve keeps exhaust condition, it is relatively convenient to operate, but the weak point that this scheme exists is, when venting finishes, needing manually to carry out switch again resets, if the user has forgotten reset operation, then when cooking next time, just can't utilize pressure normally to cook, in addition because blast pipe is the elongated tubular structure, so when cooking spoon meat, also stop up blast pipe easily, make relief valve when hypertonia, normally pressure limiting exhaust, have potential safety hazard, and the operation also have inconvenient part, as Chinese patent CN00240315.3.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of quick exhaust pressure relief safety pressure cooker simple to operation again, and steam is scalded human body in the time of both can avoiding exhaust, in the time of can avoiding user's operate miss again, and the potential safety hazard that causes relief valve to stop up.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of pressure cooker, comprise pot cover and pot body, revolving type connects between pot cover and the pot body, described pot cover is provided with quick exhaust starting drive, relief valve, the pot cover self-locking mechanism, described relief valve comprises bonnet and blast pipe, described quick exhaust starting drive comprises key switch and leverage, described key switch can drive the bonnet of leverage jack-up relief valve and realize quick exhaust pressure relief, described pot cover self-locking mechanism comprises the bullet pin, locking plate, between described key switch and the pot cover self-locking mechanism interlock is set, key switch is pressed the back and is pinned by interlock and keep the relief valve exhaust pressure relief; When action of uncapping of carrying out pot cover, the pot cover self-locking structure drives interlock throws off, and discharges key switch, and key switch resets, and relief valve cuts out.
The utility model mainly contains following useful technique effect owing to be provided with interlock between key switch and pot cover self-locking mechanism:
After key switch is pressed, bonnet by leverage jack-up relief valve, relief valve is opened, carry out quick exhaust pressure relief, it is sealed with interlock that key switch is pressed the back simultaneously, keep key switch to be in the exhaust pressure relief position, make the relief valve can the continuous exhaust pneumatic wallop pressure release, make the user simple to operation, convenient, when the pot cover folding, the pot cover self-locking mechanism drives the interlock release, discharge key switch, relief valve resets, and has solved the security hidden trouble of the blast pipe obstruction that causes because of user misoperation, operates comparatively simple and convenient.Simultaneously, key switch is far away apart from relief valve, the danger that can avoid the steam that is ejected to scald when the user operates.The utility model pressure cooker is issued to above-mentioned effect, compact overall structure in the situation that does not increase other devices.
