As shown in fig. 4, the regulator valve 1 may include a valve body 9 and a valve stem 2. Illustratively, the valve stem 2 may include a valve stem body and a protrusion. Referring to fig. 6, the projection 8 of the valve stem 2 is shown. Alternatively, the valve stem body may be a cylinder. The valve stem body may be divided into a first portion and a second portion. After the regulating valve 1 is fixed on the body of the hob, the first part is closer to the user with respect to the second part. The projection 8 may be fixed to the second part. Alternatively, the protrusion 8 may be formed integrally with the valve stem body, or may be formed separately.

For example, the valve stem 2 may further include a ring member, and the protrusion 8 may be provided on the ring member, and the ring member may be sleeved on the valve stem main body. It will be appreciated that the projection 8 may be secured to the valve stem body by sleeving the ring on the valve stem body.

Through setting up protruding portion 8 on the annular member, can form with valve rod main part components of a whole that can function independently, avoid improving current valve rod.

When the regulating valve 1 is fixed on the body of the stove, the second part of the valve rod main body can be positioned inside the body shell of the stove, and the first part of the valve rod main body can be positioned outside the body shell. The regulator valve 1 may further comprise a knob, which may be fixed to the first portion of the valve stem body. The user can adjust the firepower of the cooker through rotating the knob.

When the user adjusts the fire level, the projection 8 on the valve stem 2 may rotate as the valve stem body rotates. A plurality of trigger switches may be provided at a distance around the valve stem 2. Each trigger switch has a trigger area of a certain size. When the protrusion 8 is rotated, either trigger zone can be entered, thereby causing the trigger switch to transition from an un-triggered state to a triggered state.

Of course, the trigger switch may also be of other types.

Fig. 5 shows three micro switches 3, 4, 5. The microswitch may comprise a transmission element and an action spring, the end of which has a movable contact. In addition, the micro-switch also has a fixed contact, which may include a normally open contact and a normally closed contact. The transmission element may be a button, a push pin, a lever, etc. The external mechanical force can act on the action reed through the transmission element, and the action reed generates instantaneous action when moving to a critical point, so that the movable contact at the tail end of the action reed is quickly connected with or disconnected from the fixed contact. When the acting force on the transmission element is removed, the action reed generates reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the action reed, the reverse action is instantly finished. The micro switch has the advantages of small contact distance, short action stroke, small pressing power and quick on-off. Therefore, the microswitch is used as the trigger switch to sensitively respond to the touch of the protruding part, so that the accuracy of determining the fire power is improved, and the accuracy of linkage of the smoke stove is improved.

When the stove is in a fire-off state, the protrusion part 8 on the valve rod 2 can touch a transmission element on the ignition microswitch 3. When the user fires, the valve stem 2 rotates with the user's action and the protrusion 8 of the valve stem 2 will gradually move away from the ignition microswitch 3. When the protrusion part 8 on the valve rod 2 leaves the ignition microswitch 3, the ignition microswitch 3 can transmit an un-trigger signal (namely trigger information) to the controller 7 on the cooker through the connecting line 6 so as to control the range hood to open the middle wind shield. When the protrusion part 8 of the valve rod 2 touches the fire microswitch 4, the fire microswitch 4 can transmit a trigger signal (namely trigger information) to the controller 7 through the connecting line 6 so as to control the cigarette machine to open a big wind shield. When the protruding part 8 of the valve rod 2 touches the small fire microswitch 5, the small fire microswitch 5 can transmit a trigger signal (namely trigger information) to the controller 7 through the connecting line 6 so as to control the cigarette machine to open a small wind shield.
