Therefore, the trigger in this embodiment is a locking member that locks the cover. The triggering piece in the embodiment is automatically driven by the driving device, so that the ventilation valve can be automatically triggered, and the ventilation valve can close the ventilation holes. Compared with the existing cooking utensil with the ventilation valve with a single function, the food processor of the embodiment has higher automation degree, the food processor can be set according to requirements, when the cover body is in the covering state, the ventilation valve can close the ventilation holes through the automatic control of the trigger piece, and the expandable function of the food processor is greatly improved.

For example, when the food processor of the embodiment is used for making soybean milk beverage, the air holes can be always kept in an open state for pulping. However, when the pressure beverage is required to be made, the cooking cavity is required to be a fully-closed pressure cavity, at the moment, when the cover body is in a covering state, the driving motor can drive the trigger piece to lock the cover body, so that the risk of scalding caused by the fact that a user uncovers the cover by mistake in the pressure state is prevented. Meanwhile, in the state that the cover body is locked, the triggering piece synchronously triggers the ventilation valve to close the ventilation holes, so that the cooking cavity is a fully-closed pressure cavity. At this time, the slurry beverage in the pressure cavity is boiled under pressure, so that the pressure beverage can be manufactured. Of course, in this embodiment, the control valve may be a steam valve that is communicated with the steam generating device, and when the driving motor drives the trigger piece to lock the cover body, the valve core may be synchronously driven to rotate to a state of communicating the cooking chamber with the steam generating device, at this time, steam may be introduced into the cooking chamber through the steam generating device, and the slurry is boiled by using steam and steam pressure.

For the present embodiment, the triggering member is not limited to triggering the ventilation valve to close the ventilation hole, and the triggering member may also trigger the ventilation valve to open the ventilation hole. For example, as shown in fig. 10, another structure diagram of a linkage mechanism triggering ventilation valve is shown, and the difference between this scheme and this embodiment is that:

The breather valve comprises a valve body 31, a movable valve core 35 and a second reset spring 36, wherein the movable valve core 35 is arranged on the valve body 31, the end part of the movable valve core 35 is provided with a sealing head 34, the movable valve core 35 can axially move on the valve body 31 to drive the sealing head 34 to open and close the breather hole 20, wherein the valve body 31 is provided with a containing cavity 311, a through hole (not marked in the figure) is formed in the bottom of the containing cavity 311, the movable valve core 35 is filled 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 hoisted in the containing cavity 311, the front part of the movable valve core 35 is provided with a step 351, one end of the second reset spring 36 is abutted against the outer surface of the bottom wall of the containing cavity of the valve body 31, and the other end of the second reset spring is abutted against the step 351 of the movable valve core 35.

Meanwhile, in this solution, the linkage mechanism includes 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 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 cover is in the covering state, the trigger piece 4 extends into the locking hole 21 to lock the cover, and meanwhile, the trigger piece 4 pushes the ejector rod 62 upwards to move, so that the ejector rod 62 pushes the connecting rod 61 upwards, and the connecting rod 61 drives the movable valve core 35 to move upwards, so that the movable valve core 35 and the sealing head 34 open the ventilation holes 20.

In the scheme, when the cover body is in the covering state, the triggering piece can trigger the ventilation valve to open the ventilation holes. Of course, the linkage mechanism structure in this embodiment can also be applied to the first embodiment. When the linkage mechanism of this scheme is applied to the embodiment once, the trigger piece triggers the breather valve and opens the bleeder vent, and when the trigger piece is retrieved from the locking hole, at this moment, first reset spring can be the extension spring that is in under the tensile state, and first reset spring can pull down and hold urceolus body and valve body to make the sealing head on the valve body close the bleeder vent.

When the cover body is in the covering state, the trigger piece triggers the ventilation valve to open the ventilation holes, and the application scenarios include: the food processor is a pressure cooking utensil, before pulping, when the lid, the bleeder vent is in the closed condition, and the control valve is the water intaking valve with water supply system intercommunication, when driving motor drive case and cooking cavity intercommunication, driving motor synchronous drive trigger piece upwards stretches into locking Kong Nasuo and ends the lid, and simultaneously, the trigger piece upwards promotes the link gear motion to make the link gear drive the breather valve open the bleeder vent, the cooking cavity passes through bleeder vent and outside atmosphere intercommunication. In this state, when the water supply system is supplying water into the cooking chamber, the air can be discharged to the outside through the air holes, so that the difficulty of water supply is not caused. After water is fed, the driving motor drives the trigger piece to retract from the locking hole, and the first reset spring on the ventilation valve can reset the valve body to close the ventilation hole.

It should be noted that, in this embodiment, the trigger member is used to trigger 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 be mounted on the cover, so that the trigger does not have a locking function. It should be noted that, when the trigger piece is installed on the cover body, the trigger piece can also trigger the ventilation valve to open or close the ventilation hole through the linkage mechanism, and of course, the trigger piece can also directly trigger the ventilation valve to open or close the ventilation hole, and the linkage mechanism in the middle of the trigger piece is not required to be arranged correspondingly. Or the trigger piece does not need to be driven automatically by a driving device, the trigger piece which can be driven manually can be arranged on the machine body according to the requirement, and when the ventilation valve is required to be opened for exhausting, a consumer can manually operate the trigger piece, so that the trigger piece can trigger the ventilation valve to be opened. Similarly, when the ventilation holes are required to be closed, a consumer can also manually operate the trigger piece, so that the trigger piece triggers the ventilation valve to close the ventilation holes. Moreover, for the present embodiment, the linkage mechanism includes the connecting rod and the ejector rod, wherein the connecting rod and the ejector rod are separate pieces, and of course, the linkage mechanism may be provided as an integral piece as required.

Furthermore, it should be noted that, even if the trigger member has a function of locking the cover body, the cover body is mounted on the machine body, the mode of screwing mounting disclosed in this embodiment is not limited, the cover body can also be directly fastened on the machine body, the locking hole is provided on the peripheral wall of the cover body, the mounting portion protruding upward is provided on the machine body, and the trigger member is mounted in the mounting portion, so that when the cover body is covered, the trigger member transversely extends into the locking hole to lock the cover body.

In addition, it should be noted that, the scheme of driving the trigger by the driving device is not limited to the scheme disclosed in this embodiment, and for example, as shown in fig. 11, another schematic structural diagram of driving the trigger by the driving device is provided. The scheme differs from the embodiment in that: the transmission member 52 is not a cam, but includes a transmission wheel 521 and a transmission rod 522 mounted at an edge of the transmission wheel 521, the transmission wheel 521 is fixed to a driving shaft (not shown), and the other end of the transmission rod 522 is connected to the trigger member 4. Wherein the transmission wheel 521 and the transmission rod 522 form a crank-link mechanism.

It should be noted that, for the present embodiment and the foregoing embodiments, the transmission member and the driving shaft of the driving motor may be an integral member or a separate member. In addition, in this embodiment, the scheme of installing the ventilation valve spin card in the installation cavity is not limited to the scheme disclosed in this embodiment. In this embodiment, the outer cylinder slides relative to the sealing ring, and the sealing ring still maintains a sealing state during the sliding process, so as to prevent slurry and slurry residue in the cooking cavity from leaking into the cover body when the air holes are opened, and the cleaning cannot be performed. Of course, for this embodiment, the sealing ring may also be fixed on the inner wall of the outer cylinder, and the outer cylinder may slide with the sealing ring 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 switched between being in communication with the cooking chamber and being in turn off from the cooking chamber, wherein the valve core and the trigger member are driven by the same driving motor, and the trigger member can trigger the ventilation valve to act (open or close the ventilation hole). Therefore, in the working process of the cooking appliance in this embodiment, the ventilation valve and the control valve can be coordinated and matched with each other, for example, 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 ventilation valve also needs to be opened with ventilation holes, and the water is discharged outwards at the same time. 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 can act simultaneously or not, namely: the valve core of the water inlet valve rotates to be communicated with the cooking cavity, and then the ventilation valve is triggered by the trigger piece to open the ventilation holes. Or the ventilation valve is triggered by the trigger piece to open the ventilation holes, and then the valve core of the water inlet valve is rotated to be communicated with the cooking cavity. Or the ventilation valve opens the ventilation holes and simultaneously the valve core of the water inlet valve rotates to be communicated with the cooking cavity. The ventilation valve and the control valve are matched in a linkage way, for example, the control valve can also be a liquid discharge valve, before liquid discharge, the ventilation valve firstly opens the ventilation holes for air discharge, and then the liquid discharge valve opens the liquid discharge. Or the control valve is a steam valve, and the ventilation valve closes the ventilation holes before steam enters the cooking cavity through the steam valve.

It should be noted that, in this embodiment, the trigger piece for triggering the action of the ventilation valve and the control valve are driven by the same driving device, so that the linkage cooperation of the ventilation valve and the control valve can be well realized in the cooking process. Of course, the trigger piece and the control valve can also be driven by different driving devices, for example, the trigger piece is driven by the first driving device, the valve core of the control valve is driven by the second driving device, and in order to realize linkage cooperation work of the ventilation valve and the control valve, linkage operation design can be performed on the first driving device and the second driving device, namely, 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 realized, and finally linkage cooperation work of the ventilation valve and the control valve is realized, so that the requirements of a designer can be met. The functional action of the control valve of the present embodiment, and the way and method of the linkage cooperation between the ventilation valve and the control valve are not limited to the above-described embodiments. In addition, in the present embodiment, if the trigger has no locking function, both the trigger and the control valve may be mounted on the cover. Of course, the ventilation holes and the ventilation valve can be arranged on the machine body.

In addition, it should be noted that, in this embodiment, the cover is provided with the ventilation valve, the trigger piece is a locking piece for locking or unlocking the cover, and of course, for this embodiment, the cover may not be provided with the ventilation valve, and the trigger piece only has the function of the locking piece, but does not trigger the function of the ventilation valve, at this time, the control valve provided on the machine body may be the ventilation valve, where the valve cores of the locking piece and the control valve are driven by the same driving motor, and when the locking piece locks the cover, the control valve may be communicated with or turned off from the cooking chamber, so as to realize ventilation or sealing of the cooking chamber. The above-described mounting structure and modified structure are not limited to those disclosed in the present embodiment. And can be applied to other embodiments of the present invention without departing from the spirit of the present invention.

Fig. 12, 13 and 14 are schematic structural views of a second embodiment of the present invention. The first difference between this embodiment and the second embodiment is that: in this embodiment, the breather valve includes a hollow outer cylinder 33, a valve body 31 located above the outer cylinder 33, a movable valve core 35 installed on the valve body 31, and a second return spring 36, where a sealing head 34 is disposed at an end of the movable valve core 35, the movable valve core 35 can move on the valve body 31 to drive the sealing head 34 to open and close the breather hole 20, one end of the second return spring 36 abuts against the valve body 31, and the other end abuts against the movable valve core 35 to return the movable valve core 35 to drive the sealing head 34 to close the breather hole 20.

In this embodiment, the outer cylinder 33 is located in the mounting cavity 22 of the cover body, and the movable valve core 35, the sealing head 34 and the second return spring 36 are all installed in the outer cylinder 33, wherein a sealing ring 24 is arranged between the outer cylinder 33 and the surrounding rib 23, the sealing ring 24 is cylindrical and is tightly hooped on the outer wall of the surrounding rib 23, and the top of the sealing ring 24 is provided with a sealing rib 241 protruding outwards, the sealing rib 241 abuts against the inner wall of the outer cylinder 33, and the outer cylinder 33 is in sliding sealing with respect to the sealing rib 241.
