[0058] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0059] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0060] See also Figure 1 , this embodiment provides an intelligent control device 1 for a stove, which is connected to a stove body 2 to achieve remote shutdown and status monitoring of the stove. The stove body 2 refers to the remaining structure after the stove operation knob is removed. The intelligent control device 1 of this embodiment is connected to the original rotary rod of the stove (its structure can be seen in reference numeral 21) to achieve a rapid upgrade from an ordinary stove to an intelligent stove without changing the original stove structure. It is worth noting that in other embodiments, the stove operation knob may not be removed, and the intelligent control device 1 may be directly fixedly connected to the stove switch knob.

[0061] See also Figures 2 to 4 In this embodiment, the intelligent control device 1 is mainly composed of a rotating member 11, a driving device 12 and a transmission mechanism 13.

[0062] The rotating member 11 has a first rotating shaft portion 111, and the first rotating shaft portion 111 is sleeved on the rotating rod and rotates together with the rotating rod. Figure 4The first rotating shaft 111 has an elastic cushion 112 disposed inside the sleeve along the direction of the rotating rod insertion. The elastic cushion 112 is arranged to facilitate the adaptation and fastening of the first rotating shaft 111 to rotating rods of different thicknesses. When the intelligent control device 1 is in the power-off state, the first rotating shaft 111 serves as the operating part for rotating the rotating rod. The user can adjust the fire to the required flame scale by manually pressing and twisting the operating part. At this time, there is no difference in the method of use and user experience between manually using the intelligent control device 1 to turn on and off the stove and the stove without the intelligent control device 1 installed.

[0063] The driving device 12 specifically includes a motor 121 and a driven second rotating shaft portion 122, that is, an output shaft of the motor 121. It is worth noting that in other embodiments, the second rotating shaft portion 122 can also be another rotating shaft connected to the output shaft and driven by the motor 121. The motor 121 includes but is not limited to a brushless DC motor, a stepper motor, a brushless pan / tilt motor, a servo motor, a steering gear, etc.

[0064] The transmission mechanism 13 specifically includes a first gear 131 and a second gear 132. The types of the first gear 131 and the second gear 132 include, but are not limited to, flat gears, bevel / cone gears, end gears, spur gears, etc. The first gear 131 is fixedly sleeved on the first rotating shaft portion 111, and the second gear 132 is circumferentially fixedly arranged on the second rotating shaft portion 122. The first gear 131 and the second gear 132 are in a meshing state to realize the transmission connection between the rotating member 11 and the driving device 12. In this embodiment, the first gear 131 and the second gear 132 are always meshed. When the second gear 132 is not driven by the driving device 12, when the user manually twists the rotating member 11 to turn on the stove, the transmission mechanism 13 will drive the second rotating shaft portion 122 to rotate a certain stroke, that is, to reach the required flame size. When the driving device 12 is driving in the opposite direction of the rotation stroke, the transmission mechanism 13 will drive the first rotating shaft portion 111 to rotate accordingly, so as to drive the rotating rod to move to the closing gear position of the stove.

[0065] In another embodiment, if Figure 5 and Figure 6As shown, the intelligent control device 1 further includes a moving member 14 connected to the second gear 132. In this embodiment, the first gear 131 and the second gear 132 are not always engaged, but are engaged and separated driven by the moving member 14 moving forward and backward. Specifically, the moving member 14 is composed of a bearing 141, a connecting member 141-1, a moving rod 142 and a push-pull device 143, wherein the bearing 141 can be selected from carbon steel bearings, DryLin bearings, etc., which are sleeved on the second rotating shaft portion 122 and sleeved on the second gear 132 to achieve a fixed connection with the second gear 132, and the bearing 141 can be rotatably sleeved in the connecting member 141-1 to ensure that the connecting member 141-1, the moving rod 142 and the push-pull device 143 will not rotate with the rotation of the second gear 132; one end of the connecting member 141-1 is sleeved on the outside of the bearing 141, and the other end is connected to one end of the moving rod 142; the other end of the moving rod 142 is connected to the push-pull device 143. The push-pull device 143 is used to apply a thrust or a pull to the moving rod 142. Under the action of the thrust, the moving rod 142 drives the connecting member 141-1 to move forward, and then drives the bearing 141 to move forward, thereby the bearing 141 applies force to the second gear 132 to push it to a position where it engages with the first gear 131; under the action of the pull, the moving rod 142 drives the connecting member 141-1 to move backward, and then drives the bearing 141 to move backward, thereby the bearing 141 drives the second gear 132 to move backward to pull it to a position separated from the first gear 131. The clutch design of this embodiment ensures that the user experience can still be maintained in a good state when the motor damping is too large. It is worth noting that in other embodiments, the push-pull device 143 may not be provided, and the user may manually push and pull one end of the moving rod 142 to achieve the engagement and separation of the first gear 131 and the second gear 132, and it is not limited to electric drive.

[0067] The chassis 15 is used to fit the surface of the stove to fix the intelligent control device 1 to the stove. A through hole is provided on the chassis 15, and the through hole is used to expose the rotating rod of the stove when the chassis 15 fits the surface of the stove. The bottom surface of the chassis 15 can be provided with adhesive tape or magnets to fix it to the stove by gluing or magnetic attraction.

[0068] The housing 16 includes a top cover 161 and a shell 162. The top cover 161, the shell 162 and the bottom plate 15 can be connected by means of a card and the like.
