Therefore, the trigger in this embodiment is a locking member for locking the cover. The trigger piece in this embodiment is driven automatically through the drive arrangement, can be automatic trigger the breather valve, realizes that the breather valve closes the bleeder vent. Compare in current cooking utensil that only has single function ventilation valve, the food preparation machine of this embodiment, degree of automation is higher, and food preparation machine can set for according to the demand, when realizing that the lid is in the lid and closing the state, through the automatic control that triggers the piece, realizes ventilation valve to the closing of bleeder vent, has promoted the function that food preparation machine can expand greatly.

For example, when the food processor of the embodiment is used for making soybean milk beverage, the air holes can be always kept in the opened state for making soybean milk. However, when pressure drinks are required to be made, the cooking cavity is required to be a fully-closed pressure cavity, at the moment, the cover body is in a cover closing state, the driving motor can drive the trigger part to lock the cover body, and the risk of scalding due to mistaken opening of a user under the pressure state is prevented. Meanwhile, under the state that the cover body is locked, the trigger piece can synchronously trigger the vent valve to close the vent hole so as to realize that the cooking cavity is a fully-closed pressure cavity. At the moment, the pulp drink in the pressure cavity is subjected to pressure boiling, so that the pressure drink can be prepared. Of course, in this embodiment, the control valve can be a steam valve communicated with the steam generating device, and when the driving motor drives the trigger piece to lock the cover body, the valve core can be synchronously driven to rotate to a state that the cooking cavity is communicated with the steam generating device, at this time, steam can be introduced into the cooking cavity through the steam generating device, and the steam pressure are utilized to boil the slurry.

For the present embodiment, the triggering member is not limited to trigger the vent valve to close the vent, but may also trigger the vent valve to open the vent. For example, as shown in fig. 8, the schematic diagram of another linkage mechanism triggering the ventilation valve is shown, and the difference between the scheme and the embodiment is that:

the ventilation valve comprises a valve body 31, a movable valve core 35 and a second return spring 36, wherein the movable valve core 35 and the second return spring 36 are mounted on the valve body 31, a sealing head 34 is arranged at the end of the movable valve core 35, the movable valve core 35 can axially move on the valve body 31 to drive the sealing head 34 to open and close the ventilation hole 20, a containing cavity 311 is formed in the valve body 31, a through hole (not marked in the figure) is formed in the bottom of the containing cavity 311, the movable valve core 35 is installed in the containing cavity 311 and extends out of the valve body 31 through the through hole, the rear end of the movable valve core 35 is hung in the containing cavity 311, a step 351 is arranged on the front portion of the movable valve core 35, one end of the second return spring 36 abuts against the outer surface of the bottom wall of the containing cavity of the valve body 31, and the other end of the second return spring abuts against the step 351 of the movable valve core 35.

Meanwhile, in the scheme, the linkage mechanism comprises a connecting rod 61 and a push rod 62, one end of the connecting rod 61 is connected with the movable valve core 35 into a whole, the other end of the connecting rod directly abuts against the rear end of the push rod 62, and the front end of the push rod 62 is inserted into the locking hole 21. When the lid is in the lid and closes the state, trigger 4 stretches into in the locking hole 21, carries out the locking to the lid, and simultaneously, trigger 4 upwards promotes the motion of ejector pin 62 to make ejector pin 62 upwards promote connecting rod 61, connecting rod 61 drives movable valve core 35 upward movement, so that movable valve core 35 and sealing head 34 open bleeder vent 20.

In this scheme, when the lid is in the lid state of closing, trigger piece can trigger the breather valve and open the bleeder vent. Of course, the linkage mechanism structure in the present embodiment may also be applied to the first embodiment. When the linkage mechanism of the scheme is applied to the embodiment, the trigger piece triggers the vent valve to open the vent hole, and when the trigger piece is withdrawn from the locking hole, at the moment, the first reset spring can be a stretching spring in a stretching state, and the first reset spring can pull the outer cylinder body and the valve body downwards so that the sealing head on the valve body closes the vent hole.

When the lid is in the closed state, trigger the spare and trigger the breather valve and open the bleeder vent, its applied scene is for example: the food processing machine is a pressure cooking appliance, before pulping, when the cover body is covered, the air vent is in a closed state, the control valve is a water inlet valve communicated with a water supply system, when the driving motor drives the valve core to be communicated with the cooking cavity, the driving motor synchronously drives the trigger piece to extend upwards into the locking hole to lock the cover body, and meanwhile, the trigger piece upwards pushes the linkage mechanism to move, so that the linkage mechanism drives the air vent valve to open the air vent, and the cooking cavity is communicated with the external atmosphere through the air vent. In this state, when the water supply system supplies water into the cooking chamber, air can be discharged to the outside through the ventilation holes, and thus, difficulty in water supply is not caused. After the water inlet is finished, the driving motor drives the trigger piece to withdraw from the locking hole, and the first reset spring on the vent valve can reset the valve body to close the vent hole.

It should be noted that, for the present embodiment, the triggering member is used for triggering the ventilation valve to open or close the ventilation hole, and also has a locking function. Of course, for the present embodiment, the trigger and the driving device for driving the trigger may also be mounted on the cover, so that the trigger does not have a locking function. It should be noted that, when the trigger is installed on the cover body, the trigger may also trigger the vent valve to open or close the vent hole through the linkage mechanism, and of course, the trigger may also directly trigger the vent valve to open or close the vent hole, and accordingly, the linkage mechanism in the middle may not be needed. Or, the trigger part does not need to be driven automatically by a driving device, and the trigger part capable of being driven manually can be arranged on the machine body as required. Similarly, when the air hole needs to be closed, a consumer can also manually operate the trigger piece, and the trigger piece triggers the air hole valve to close the air hole. Moreover, for the present embodiment, the linkage mechanism includes a connecting rod and a push rod, wherein the connecting rod and the push rod are separate pieces, and of course, the linkage mechanism can be configured as a single piece as required.

Moreover, it should be noted that even if the trigger has a function of locking the cover body, the cover body is mounted on the machine body, and the manner of screwing and mounting disclosed in this embodiment is not limited, the cover body may be directly fastened to the machine body, and the peripheral wall of the cover body is provided with a locking hole, and the machine body is provided with an upwardly protruding mounting portion, and the trigger is mounted in the mounting portion, so that when the cover body is closed, the trigger transversely extends into the locking hole to lock the cover body.

In addition, it should be noted that the scheme that the driving device drives the trigger member to move is not limited to the scheme disclosed in this embodiment, and for example, as shown in fig. 9, another schematic structural diagram that the driving device drives the trigger member to move is shown. The difference between the scheme and the first embodiment is that: the transmission member 52 is not a cam, but comprises a transmission wheel 521 and a transmission rod 522 arranged on the edge of the transmission wheel 521, wherein the transmission wheel 521 is fixed on a driving shaft (not shown in the figure), and the other end of the transmission rod 522 is connected with the trigger 4. Wherein the transmission wheel 521 and the transmission rod 522 form a link mechanism.

It should be noted that, for the present embodiment and the foregoing solutions, the transmission member and the driving shaft of the driving motor may be an integral piece or may be a separate piece. In the present embodiment, the mode in which the ventilation valve plug is attached to the attachment chamber is not limited to the mode disclosed in the present embodiment. It should be noted that, in this embodiment, the outer cylinder slides relative to the sealing ring, and the outer cylinder still maintains a sealing state with the sealing ring in the sliding process, so as to prevent the slurry and the slurry residue in the cooking cavity from leaking into the cover body when the air vent is opened, and thus the cleaning and the cleaning cannot be performed. Certainly, for this embodiment, the sealing ring may also be fixed to the inner wall of the outer cylinder, and the outer cylinder may take the sealing ring to slide relative to the surrounding rib in the floating process, and the sealing ring and the surrounding rib maintain a sealing state in the sliding process.

It should be noted that, in this embodiment, the control valve has a rotatable valve core, and the valve core can be rotationally switched between being communicated with the cooking chamber and being disconnected from the cooking chamber, wherein, the valve core and the triggering member are both driven by the same driving motor, and the triggering member can trigger the vent valve to act (open or close the vent). Therefore, in the working process of the cooking appliance in the embodiment, the vent valve and the control valve can be in linkage and matched with each other, for example, as mentioned above, the control valve is a water inlet valve, when water needs to be fed into the cooking cavity, the water inlet valve is opened, the vent valve also needs to be opened, and the outward air exhaust is realized while the water is fed. It should be noted that, in this working process, the water inlet valve and the ventilation valve perform linkage and cooperation, wherein the water inlet valve and the ventilation valve may or may not simultaneously act, that is: the valve core of the water inlet valve rotates to be communicated with the cooking cavity, and then the vent valve is triggered by the trigger piece to open the vent hole. Or the vent valve is triggered by the trigger part to open the vent hole, and then the valve core of the water inlet valve rotates to be communicated with the cooking cavity. Or when the vent valve opens the vent hole, the valve core of the water inlet valve rotates to be communicated with the cooking cavity. The ventilation valve and the control valve are in linkage fit, for example, the control valve can also be a liquid discharge valve, before liquid is discharged, the ventilation hole is opened firstly by the ventilation valve for exhausting, and then the liquid discharge valve is opened for discharging liquid. Or the control valve is a steam valve, and before steam is fed into the cooking cavity through the steam valve, the vent hole is closed by the vent valve.

It should be noted that, in this embodiment, the triggering member for triggering the vent valve to operate and the control valve are driven by the same driving device, so that the vent valve and the control valve can be well cooperated to work in the cooking process. Certainly, the trigger and the control valve may also be driven by different driving devices, for example, the trigger is driven by a first driving device, and the valve core of the control valve is driven by a second driving device, so as to achieve linkage cooperation of the vent valve and the control valve, a linkage operation design may be performed on the first driving device and the second driving device, that is, when the first driving device is controlled, the second driving device is synchronously controlled, linkage operation of the first driving device and the second driving device is achieved, and finally linkage cooperation of the vent valve and the control valve is achieved, which also can meet the requirements of designers. It should be noted that the functional function of the control valve and the manner and method of the linkage and cooperation between the vent valve and the control valve in the present embodiment are not limited to the above-mentioned solutions in the present embodiment. In the present embodiment, if the trigger has no locking function, both the trigger and the control valve may be mounted on the lid. Of course, the air vent and the air vent valve can be arranged on the machine body.
