The microprocessor and wireless transceiver module 5 is electrically connected with the vibration sensor 7 and the triaxial acceleration sensor 8 respectively to realize signal transmission and execution control. The button cell 9 adopts a disposable lithium button cell, and the normal service life is 3-4 years. The circuit board 2 is fixed in the first installation cavity of the shell body 1, and the knob top cover 3 is buckled with the shell body 1 and fixed by screws to seal the circuit board 2 in the first installation cavity of the shell body 1. Because the shaft diameter of a switch of a cooker does not have a unified standard at present, and multiple sizes coexist, the intelligent knob device provides a second mounting cavity 11 for mounting the replaceable switch shaft sleeves 4 with different inner diameters, and the intelligent knob is matched with the shaft diameters of the switch of knob switches of different cookers or different devices by replacing the switch shaft sleeves 4 with different inner diameters.

As shown in figure 1, the included angle 14 between the direction of the stove switch axis 13 and the horizontal direction is less than +/-70 degrees, and the stove is suitable for adopting the scheme of the patent. After a user takes down an original knob switch head of the stove, a switch shaft sleeve 4 with a proper aperture is selected according to the size of a switch shaft 12 of the stove and is clamped on the switch shaft 12. A metal reed is arranged in a third mounting cavity 43 in the switch shaft sleeve 4 to press the switch shaft 12 to prevent loosening and slipping. A buckle 10 is arranged on the mounting port of the second mounting cavity 11 of the shell main body 1; the switch shaft sleeve 4 comprises a bulge 42 embedded in the second mounting cavity 11 and a base 41 which is integrated with the bulge 42 and used for limiting the embedding depth of the bulge 42; the base 41 is provided with a limiting groove 44 which is matched with the buckle 10 for use and is used for limiting the rotation and the displacement of the switch shaft sleeve 4 relative to the shell body 1, the bulge 42 is embedded into the second mounting cavity 11 of the shell body 1, and then the buckle 10 is buckled in the limiting groove 44 on the base 41, so that the switch shaft sleeve 4 can be embedded and firmly clamped and fixed. At the moment, the intelligent knob can replace the switch function of the original knob of the cooker.

Due to the special limitations of knob size and application, the circuit can only be powered by a small battery with low capacity. In addition for it is convenient to change the battery, the intelligence knob of this embodiment still includes knob top cap 3, is provided with the screw through-hole on shell main part 1 and the circuit board 2, and the screw through-hole uses with the screw is supporting for will be fixed with the circuit board 2 of sealed first installation intracavity with knob top cap 3 and the 1 lock of shell main part. A microprocessor and wireless transceiver module 5, a giant magnetoresistance angle sensor 6, a vibration sensor 7 and a triaxial acceleration sensor 8 are fixedly mounted on a first side surface (i.e. a side far away from a first mounting cavity opening) of the circuit board 2; the giant magnetoresistance angle sensor 6 is arranged at the position of the axial lead of the first mounting cavity of the knob and is positioned within an effective distance capable of sensing and positioning the magnetic field of the magnet, and the XY axis is perpendicular to the switch axial line 13. The three-axis acceleration sensor 7 is mounted in the vicinity of the giant magnetoresistive angle-sensor configuration 6, likewise with the XY-axis perpendicular to the switch axis 13 and the Z-axis parallel to the switch axis 13. Microprocessor passes through circuit board 2 respectively with wireless transceiver module 5, giant magnetoresistance angle sensor 6, vibration sensor 7 and triaxial acceleration sensor 8 electrical connection, and the second side (be close the one side of first installation cavity accent promptly) fixed mounting of circuit board 2 has power module (button cell 9 promptly), just can change the battery through dismantling knob top cap 3.

The cross sections of the switch shaft sleeve 4 and the second mounting cavity 11 are square. The square switch shaft sleeve 4 can adapt to switch shafts 12 with different trimming designs, so that the compatibility of the switch shaft sleeve 4 is improved.

In order to prolong the service life of the battery to more than 3-4 years to the maximum extent, the microprocessor and the wireless transceiver 8 are in a dormant state at ordinary times, are awakened by the vibration sensor 7 when in use, and then control the button battery 9 to supply power to the relevant angle measurement sensors (namely the giant magnetoresistance angle sensor 6 and/or the triaxial acceleration sensor 8). The vibration sensor 7 is a high-sensitivity and ultra-low power consumption micromechanical vibration sensor. When the knob is rotated, the vibration sensor 7 is triggered to wake up the microprocessor and wireless transceiver 5, which are normally in a dormant state. The microprocessor and the wireless transceiver 5 utilize the gravity acceleration components in the three-axis directions measured by the three-axis acceleration sensor 8 to obtain the rotation angle 14 of the knob through a triangular projection algorithm, and further calculate whether the stove switch is opened or not and the degree of fire power opening.

In a preferred scheme, as shown in fig. 4, the plane of the cooker switch panel is parallel to the horizontal plane, so that the axial direction of the switch shaft 12 is almost completely coincident with the gravity line (perpendicular to the horizontal plane), the gravity component induced by the three-shaft acceleration sensor 8 on the X, Y shaft is too small to be used for calculating the rotation angle 14, and the cooker needs to be provided with a positioning magnet. After a user takes down an original knob of the stove, two positioning magnets are arranged on two sides of a switch shaft 12 on the surface of the stove and are opposite to the lower part of the knob, and magnetic poles of the two magnets facing the knob are opposite to each other. The installation positions of the two magnets do not need to be accurately positioned, and the intelligent knob with the angle zero clearing function can automatically set the rotation angle 14 when the switch is turned off to be a zero angle.

The intelligent knob is provided with 10 switch shaft sleeves 4, and referring to fig. 3, the switch shaft sleeves are respectively C1, C2, D2, D2S, D3, D4, D5, D6, P2 and P2S. The 10 switch shaft sleeves 4 are respectively used for adapting the switch shafts 12 of different types of stoves on the market, such as D2S, a small part D1 is inserted into a hole of D2, and P2S, a small part P1 is inserted into a hole of P2. The D2S holes are shallower in length to accommodate cookers with furnace axes suitable for D2 but shorter, and the P2S holes are shallower in length to accommodate cookers with furnace axes suitable for P2 but shorter.
