The utility model has the advantages that:

the utility model provides a when the weight is placed on the blast pipe with correct gesture, the blast pipe can be sealed to the weight, and can the relative blast pipe rotation lift, and when the weight dislocation was placed on the blast pipe, because the lateral wall of cavity still is equipped with prevents slow-witted portion, and prevent that slow-witted portion can take place to interfere with the weight of misplacing, consequently when making the unable sealed blast pipe of weight, still the part that the weight that can significantly reduce is located the cavity, the part in the cavity outside has been increased promptly, the assembler sees the part that the weight is located the cavity outside more after, alright know the weight dislocation and place, correct the gesture of placing of weight afterwards, make the weight install in place can, avoid appearing because of the weight dislocation place the unable condition of pushing up in the culinary art intracavity when leading to cooking takes place, cooking utensil's culinary art efficiency and culinary art effect have been guaranteed.

The guide structure includes guide way and protruding muscle, and the peripheral side local recess of weight forms the guide way, and the guide way has the open socket down, and the protruding muscle is located on the lateral wall of cavity and through the vertical guide way that inserts of socket, and the guide way is including the oblique wall of direction, goes up and down with relative blast pipe through the oblique wall of direction and the cooperation of protruding muscle when the weight is rotatory. By the design, the side wall of the concave cavity is enhanced, and meanwhile, the guide groove can be exposed out of the outer periphery of the heavy hammer, so that the guide groove can be conveniently cleaned in the later period; in addition, when the weight is rotated, because the position of the convex rib is unchanged, the weight can realize the lifting motion through the sliding fit of the guide inclined wall and the convex rib, so that the guide structure is simpler, and the processing and forming of the weight and the exhaust seat are facilitated.

The fool-proof part comprises a convex rib, and when the heavy hammer is placed in a staggered mode, the convex rib and the bottom surface of the heavy hammer outside the guide groove are in interference. Compared with the placing posture of the convex rib inserted into the guide groove, the convex rib is interfered with the bottom surface of the heavy hammer outside the guide groove, so that the mounting height of the heavy hammer can be raised, more parts of the heavy hammer exposed outside the concave cavity are formed, and an assembler can know the misplacement of the heavy hammer; in addition, the fool-proof part is formed by the convex ribs, so that the dual-purpose effect of one object can be realized, and the structure of the exhaust seat is simplified.

The periphery side of weight still is equipped with shifting block and the dog that the symmetry set up, the bottom surface of shifting block is less than the dog bottom surface, the lateral wall of cavity is equipped with dark breach and shallow breach, the shifting block is rotatory elevating movement in dark breach, one side backstop shifting block of dark breach is with the last rotation angle of restriction weight, the dog is rotatory elevating movement in shallow breach, one side backstop dog of shallow breach is with the angle of screwing down of restriction weight, prevent that slow-witted portion still includes shallow breach, when the weight misplaces, shallow breach and shifting block are interfered. By the design, the limit on the upward rotation angle and the downward rotation angle of the heavy hammer can be realized, so that the limit on the lifting distance of the heavy hammer is realized through the limit on the rotation angle, and the control on the steam discharge amount is further realized; in addition, because shifting block and dog symmetry set up, easily exist the dislocation and place and lead to shifting block and the cooperation of shallow breach, and dog and deep breach complex assembly methods, because the shallow breach can take place to interfere with the shifting block this moment, the mounting height of weight is raised to consequently accessible shallow breach for the weight exposes in the part in the cavity outside more, so that the assembler knows the weight dislocation and places.

The pot cover further comprises an electric push rod which pushes the shifting block to move so as to enable the heavy hammer to rotate. By the design, the heavy hammer can be manually pushed away by a user to open the exhaust pipe, so that the risk that the user is scalded is avoided.

The pot cover still includes releasable connection's lining lid and inner cup, and exhaust apparatus installs and covers including and run through the lining lid, and the lining is covered and is equipped with the sealed apron of detaining and put in the exhaust apparatus outside, and the distance between the roof of weight top and apron is H when the blast pipe is closed to the weight, and when the weight misplaced, the weight highly was H1 in the cavity outside was revealed, satisfied H1 > H. So design, when the assembler did not find the weight dislocation and place on the blast pipe and continue to assemble the pot cover, the apron can take place to interfere with the weight and lead to exhaust apparatus can't pack into in the space that the apron injectd the formation, and then reminds the assembler the weight mistake dress, makes the assembler can correct the posture of placing of weight and makes its installation target in place.

The exhaust device also comprises a float valve arranged on the exhaust seat, and the side wall of the exhaust seat is provided with an exhaust port. Because the float valve and the exhaust pipe are arranged through the inner cover, the float valve is arranged on the exhaust seat, so that the float valve and the exhaust pipe are matched to realize two-point positioning of the exhaust seat, and the exhaust seat is prevented from deviating relative to the inner cover, thereby facilitating the assembly of the exhaust seat and the inner cover; secondly, a part of steam discharged by the float valve and the exhaust pipe can recoil to enter the exhaust seat after meeting the cover plate, and the arrangement of the exhaust port avoids steam water from being accumulated in the exhaust seat.

The bottom surface of the exhaust seat is provided with a plurality of bulges arranged at intervals, and the bulges are supported on the inner cover. By the design, the contact area between the exhaust seat and the inner cover can be reduced, so that the heat directly transferred to the exhaust seat by the inner cover is reduced, and the problem of deformation caused by overhigh temperature of the exhaust seat is avoided.

The periphery of the heavy hammer is provided with a balance rib which is in sliding fit with the inner side surface of the concave cavity. By the design, the heavy hammer can keep balance during rotating and lifting, and the problem that the heavy hammer turns on one side in the rotating and lifting process is solved.

The top of the weight is provided with a first indicating arrow, the wall of the cavity is provided with a second indicating arrow, and when the weight is installed in place, the first indicating arrow corresponds to the second indicating arrow. By the design, the heavy punch can be further prevented from being placed by an assembler in a staggered mode.

These features and advantages of the present invention will be disclosed in more detail in the following detailed description and the accompanying drawings.
