In a state where the valve element 2 is located at 130 degrees with respect to the valve cavity (i.e., the valve element 2 is located at an angle "F" as shown in fig. 1), as shown in fig. 8, the central fire is a large fire, the outer ring fire is a small fire, the middle ring fire is a closed, and at this time, the outer ring fire of the burner has been reduced.
In a state where the valve element 2 is located at 165 degrees with respect to the valve chamber (i.e., the valve element 2 is located at the "G" angle position shown in fig. 1), as shown in fig. 9, the central fire is the middle fire, the outer ring fire is closed, the middle ring fire is closed, and the fire power of the burner is further reduced.
In a state where the valve element 2 is located at a position of 180 degrees with respect to the valve chamber (i.e., the valve element 2 is located at an "H" angle position shown in fig. 1), as shown in fig. 10, the central fire is a small fire, the outer ring fire is closed, and the middle ring fire is closed.
In a state that the valve core 2 is positioned at a position of 215 degrees relative to the valve cavity (i.e. the valve core 2 is positioned at an angle "I" shown in fig. 1), as shown in fig. 11, the central fire is a small fire, the outer ring fire is closed, and the middle ring fire is closed; the valve core 2 has the minimum firepower corresponding to the burner when the valve core is positioned at 180-215 degrees, and can be applied to heat preservation of foods in the cooker.
In a state that the valve core 2 is at a 245 degree position relative to the valve cavity (i.e. the valve core 2 is at a J angle position shown in fig. 1), as shown in fig. 12, the central fire is a small fire, the outer ring fire is a small fire, and at the moment, the outer ring fire of the burner is ignited again; because the middle ring fire air outlet holes are partially communicated with the middle ring fire air inlet 103, the middle ring fire spraying opening of the burner is ignited at the moment, and the middle ring fire is in a small fire state; the middle ring fire acts as a 'pressurizing fire', and in the state, the center fire, the middle ring fire and the outer ring fire are all in a small fire state, so that the effect of heating the cooker is most uniform, the food is uniformly heated, the uneven cooking degree of the food in the cooker is avoided, and the efficient cooking is facilitated. Because the combustion of the middle ring fire is arranged at the position corresponding to the rotary knob and rotated anticlockwise to the tail end position (or understood as the back position), the phenomenon that the food is burnt due to too strong fire of the burner caused by misoperation of a user is avoided.
In a state where the valve core 2 is at a 270 degree position relative to the valve cavity (i.e., where the valve core 2 is at a "K" angle position shown in fig. 1), as shown in fig. 13, the central fire is a big fire, the outer ring fire is a big fire, and the middle ring fire is a big fire.
In some embodiments, as shown in fig. 14, in the fourth height position, the valve core 2 is formed with the small central fire outlet hole 232, in other words, the small central fire outlet hole 232 belongs to the small central fire outlet hole, for example, in the fourth height position, the valve core 2 is formed with two small central fire outlet holes 232 and two large central fire outlet holes together with four central fire outlet holes, the valve core 2 is formed with concave platforms 203, each concave platform 203 correspondingly forms a cavity, the small central fire outlet holes 232 are arranged in the corresponding concave platform 203, as shown in fig. 10, by arranging the concave platforms 203, for example, because the small central fire outlet holes 232 have smaller diameters, if the corresponding concave platforms 203 are not arranged, the small central fire outlet holes 232 are only communicated with the central fire air inlet 104 in a smaller angle range, so that the fire power regulating function is inconvenient for users to operate, in order to avoid the condition that the central fire is cut off when the large central fire outlet holes are switched from the large central fire outlet holes to the small central fire outlet holes 232, as shown in fig. 8, the small central fire outlet holes are required to be arranged at the edges of the large central fire outlet holes, in other words, the small central fire outlet holes are required to be smoothly switched to have the diameters of the corresponding concave platforms 203, and the diameters of the small central fire outlet holes are smaller than the corresponding concave platforms 203, and the small fire inlets are arranged to have the diameters of the straight fire holes and have the diameters and the diameters of the corresponding concave fire outlets and are favorable to be arranged.
Further, as shown in fig. 14, a conical boss 204 is correspondingly formed at the bottom of the concave table 203, a small central gas outlet hole 232 is coaxially formed to extend through the conical boss 204, a flare 2041 is formed at the outer end of the conical boss 204, the flare 2041 can be specifically understood as a section of gradually increasing gas flow channel from inside to outside, the small central gas outlet hole 232 is coaxially connected to the corresponding flare 2041, and as shown in fig. 9, for example, by arranging the flare 2041, when the small central gas outlet hole 232 is not aligned with the central gas inlet 104, the gas flow of the combustible gas sprayed from the corresponding flare 2041 is in a diffuse shape, which is beneficial for the gas flow of the combustible gas to flow to the central gas inlet 104 easily.
In conclusion, the 90-degree three-cavity piezoelectric energy-saving valve is beneficial to enriching the firepower gear of the gas stove and facilitating smooth cooking, thereby being beneficial to saving cooking time, namely saving energy and adapting to diversified cooking processes. The number and the size of the ignition vent holes, the outer ring fire vent holes, the middle ring fire vent holes and the center fire vent holes can be correspondingly set by a person skilled in the art according to the description of the fire gear corresponding to each angle position of the valve core 2 relative to the valve cavity, and the person skilled in the art can complete the manufacture and the specific use of the scheme of the invention according to the description and the accompanying drawings; the drawings of the present invention are merely exemplary embodiments, and are not intended to limit the scope of the present invention, which is defined by the claims, as long as the equivalent structure changes made by the description of the present invention and the contents of the drawings, or the equivalent structure changes can be directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
