Detailed Description

The present invention will be further described with reference to the accompanying drawings. An electric frying pan with micropressure function, its characterized in that: the cooker cover comprises a cooker body 1 and a cooker cover 2, wherein a mounting ring 21 is arranged at the bottom of the cooker cover 2, a sealing ring 3 is sleeved outside the mounting ring 21, the sealing ring 3 seals a gap between the mounting ring 21 and the cooker body 1, a vent groove 22 is also formed in the cooker cover 2, and a pressure relief device 4 is embedded in the vent groove 22; the pressure relief device 4 comprises a mounting seat 41, the mounting seat 41 extends into the vent groove 22, an exhaust hole 411 is arranged in the mounting seat 41 and penetrates through the body of the mounting seat, and the exhaust hole 411 conducts air inside the pot body 1 and outside air; the pressure relief device 4 further comprises a sealing cover 42 embedded in the exhaust hole 411, and the sealing cover 42 is arranged for sealing the exhaust hole 411; the bottom of the sealing cover 42 protrudes downwards to form a plurality of sealing columns 421, correspondingly, mounting holes 412 are distributed around the exhaust holes 411, and the sealing columns 421 extend into the mounting holes 412 to be connected therewith.

The outer cylindrical surface of the sealing column 421 is provided with a limiting table 422 in a protruding manner, and the limiting table 422 is clamped on the lower end surface of the mounting hole 412.

The sealing ring 3 is arranged in a V shape, and two side walls of the sealing ring 3 are respectively coated on the upper end surface and the inner side surface of the edge of the pot body 1 to form sealing.

The length of the sealing columns 421 is greater than the depth of the cross section of the mounting hole 412, and at least three sealing columns 421 are provided.

The bottom of the limit table 422 extends downwards to form a guide column 423.

The outer cylindrical surface of the limiting table 422 is inclined downwards to form a guide inclined surface.

The sealing column 421, the guiding column 423, the limiting table 422 and the sealing cover 42 are integrally formed by injection molding of rubber materials.

The working principle is as follows: in the present case, the bottom of pot cover is provided with the collar, in order to seal the clearance between the pot cover and the pot body, is equipped with the sealing ring at the collar overcoat, and the clearance between the sealing ring seal and the two, and the pot cover seals fixedly under the pressure of its dead weight with the pot body. Further, the sealing ring is arranged in a V shape, and two side walls of the sealing ring are respectively coated on the upper end face and the inner side face of the edge opening of the pot body, so that a sealing state is formed, two sealing devices are arranged, the sealing performance between the pot cover and the pot body is better, and the connection is more stable.

In order to timely process the pressure difference in the electric frying pan during the operation, a vent groove is arranged on the pan cover, and a pressure relief device is embedded in the vent groove. Wherein, pressure relief device has included the mount pad, and the mount pad extends into this air channel, runs through its body in the mount pad is inside to be provided with the exhaust hole, and the exhaust hole switches on the inside air with the outside of pot body. Pressure relief device has still included the embedded sealed lid of installing in the exhaust hole, and sealed bottom of covering is outstanding downwards and is formed with the sealed post of a plurality of, correspondingly, has distributed at the exhaust hole periphery has the mounting hole, and sealed post extends to be connected with the mount pad in this mounting hole to realize sealed lid and seal the setting to the exhaust hole.

After the electric frying pan works for a period of time, the air pressure in the pan rises and is kept higher than the atmospheric pressure, so that the quick maturity of cooked food is facilitated, and the cooking efficiency is improved. When atmospheric pressure rises to certain degree, for example 1.5kPa, pressure rises and makes sealed lid upwards displace and produce and lose heart to avoid too high atmospheric pressure to lead to incident such as explosion easily, with the within range of setting of atmospheric pressure restriction. When the pressure is released until the air pressure in the pan reaches a certain degree, such as lower than 0.5kPa, the sealing column can automatically reset and move downwards under the action of the elastic tension, the sealing cover seals the exhaust hole again, and the effective pressure release and pressure maintaining can be carried out on the air pressure in the pan in time, thereby ensuring the efficiency and the safety of the electric frying pan. In addition, in the process of pressure relief of the electric frying pan, a user does not need to perform manual pressure relief operation, so that the operation of the user is facilitated, and the use safety of the user is guaranteed.

Meanwhile, the limiting table is arranged on the outer cylindrical surface of the sealing column in a protruding mode, and after the sealing column is installed, the limiting table is clamped on the lower end face of the installation hole. The sealing device has the advantages that the air pressure is large, the sealing column moves upwards to relieve pressure, the limiting table can limit the upward moving stroke of the sealing column, the phenomenon that the sealing cover is popped out and separated due to the fact that the pressure is too large is avoided, the use safety of a user is protected, and therefore the sealing device can be widely popularized and used.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
