When the driving member 61 drives the shielding member 62 to abut against the inner wall of the exhaust passage 50 opposite to the opening, at this time, the sectional area of the exhaust passage 50 shielded by the shielding member 62 is maximum, the flow rate of the steam flowing in the exhaust passage 50 is minimum, and when the driving member 61 drives the shielding member 62 to move away from the inner wall of the exhaust passage 50 opposite to the opening along the opening, the sectional area of the exhaust passage 50 shielded by the shielding member 62 is gradually reduced, the flow rate of the steam flowing in the exhaust passage 50 is gradually increased until the shielding member 62 is flush with the inner wall of the exhaust passage 50 on the side where the opening is located, at this time, the exhaust passage 50 is not shielded by the shielding member 62 at all, and the flow rate of the steam flowing in the exhaust passage 50 is maximum. Therefore, by controlling the position of the driving member 61 for driving the shielding member 62 to move along the axial direction of the opening, the sectional area of the exhaust passage 50 can be precisely controlled, so that the steam flow can be adjusted to adapt to the requirements of different recipes and different pressures.

In some embodiments, the diameter of the aperture is greater than the diameter of the vent passageway 50, the outer perimeter of the shield 62 sealingly engages the perimeter side wall of the aperture such that the shield 62 is able to completely shield the vent passageway 50 when the shield 62 is moved axially along the aperture into abutment with the inner wall of the vent passageway 50 opposite the aperture, the vent passageway 50 is completely truncated, the vapor flow is zero, the cross-sectional area of the vent passageway 50 shielded is progressively smaller and the flow of vapor through the vent passageway 50 is progressively greater when the shield 62 is moved away from the inner wall of the vent passageway 50 opposite the aperture.

The shielding member 62 is arranged through the transfer pipe 53, the second end of the first branch pipe 51 and the second end of the second branch pipe 52 are respectively positioned at two opposite sides of the shielding member 62, the driving member 61 drives the shielding member 62 to move along the axial direction of the transfer pipe 53 so that the shielding member 62 is close to or far away from the inner wall of the first end of the transfer pipe 53, when the shielding member 62 is close to the inner wall of the first end of the transfer pipe 53, the space of the transfer pipe 53 which is not shielded is smaller, namely the larger the cross section area of the exhaust passage 50 which is shielded by the shielding member 62 is, the smaller the steam flow is, and vice versa. In this case, the diameter of the opening may be equal to or smaller than the diameter of the exhaust passage 50, that is, the diameter of the switching pipe 53 may be equal to or smaller than the diameters of the first branch pipe 51 and the second branch pipe 52, and the flow rate of the communication between the first branch pipe 51 and the second branch pipe 52 may be adjusted by the movement of the shutter 62.

In this embodiment, the first end of the first connecting pipe 54 and the first end of the second connecting pipe 55 are coaxially disposed, so that when the shielding member 62 moves axially along the adapting pipe 53 to a position where the first end of the first connecting pipe 54 and the first end of the second connecting pipe 55 are not shielded, steam can flow from the first end of the first connecting pipe 54 directly to the first end of the second connecting pipe 55, the steam flowing path is shortest, and the flowing efficiency is higher.

In order to fix the first connecting pipe 54, the second connecting pipe 55 and the switching pipe 53 conveniently, the exhaust pipe 5 further comprises a fixing ring 56 fixed on the box 1, the fixing ring 56 is of an annular structure, through holes for the first connecting pipe 54 and the second connecting pipe 55 to pass through are formed in the periphery of the fixing ring 56, the switching pipe 53 is coaxially fixed in the fixing ring 56, first ends of the first connecting pipe 54 and the second connecting pipe 55 respectively pass through corresponding through holes and are connected with the peripheral wall of the switching pipe 53 positioned in the fixing ring 56, the fixing ring 56 plays a limiting and fixing role on the first connecting pipe 54 and the second connecting pipe 55, and meanwhile the first connecting pipe 54, the second connecting pipe 55 and the switching pipe 53 are connected into a whole.

Of course, the first connection pipe 54, the second connection pipe 55, the adapter pipe 53 and the fixing ring 56 may be manufactured separately and finally assembled as a whole.

Further, one axial end of the fixing ring 56 is closed to form a bottom wall 561, and the first end of the adapter tube 53 is integrally formed on the bottom wall 561 of the fixing ring 56, so as to close the first end of the adapter tube 53 and fix the adapter tube 53 on the fixing ring 56, thereby having a more compact structure.
