This creation is about an improved automatic gas shut-off device for stoves, especially a kind of simple setting, easy operation and use, convenient and fast, which can make the shut-off device installed on the stove without direction, so as to achieve multi-dimensionality of installation and use. The gas automatic shut-off device for stoves has the effect of expanding the scope of use, and is in line with practical applicability, ideality and progress.

Press, in the process of cooking, it is often heard that the cooker forgets to turn off the fire, which leads to empty burning, dry burning of the container or cooking utensils, and then causes a fire to cause heavy casualties and losses of life and property. For this reason, the applicant A variety of safety protection devices for stoves that can automatically shut off gas have been provided, such as application No. 107216888, No. 109204768, etc., hoping to effectively improve the aforementioned danger caused by forgetting to turn off the fire; the structure of these products is mainly related to the safety The closing device of the protective device is installed behind the ignition shaft of the stove. By turning the knob of the closing device, actions such as igniting the stove, adjusting the firepower or closing the fire can be implemented, and the cooking food is forgotten to turn off the fire for some reason (such as Boiling water or cooking soup...), so that when the cooking time exceeds the fire off time set by the closer, the clutch motor of the closer will automatically start to drive the knob to turn in the opposite direction to turn off the fire. According to this, The operation of the stove for cooking food can effectively prevent fire accidents caused by forgetting to turn off the stove, and achieve the effect of improving the safety of use. In fact, after these products were launched on the market, they were widely welcomed and used by consumers, and they were repeatedly valued and encouraged by various awards issued by the government and foreign units. Zuoren dare not or forget to further refine and improve this product, hoping to exert greater benefits and provide users with simpler, more convenient and faster use effects.

That is to say, before the creator created the closer of the stove safety protection device that can automatically turn off the gas, since the display screen is set on the structure, it can display the time numbers for cooking and preparing to turn off the gas, so watch the time according to Based on the relationship between the angle of the numbers and the corresponding knob, as shown in Figure 1 and Figure 2, the form of the closer 1 of the safety protection device must be designed to be horizontal and vertically corresponding to the display screen 11 and the rotary handle 12. Form closer 1, or as shown in Figure 3 and Figure 4, the display screen 11 and the rotary handle 12 must be designed to be parallel to each other and correspond to the straight form closer 1, accordingly, as shown in Figure 5 and Figure 6 , the user can choose to install the horizontal closer 1 (as shown in Figure 5) or choose to install the straight closer 1 (as shown in Figure 6) according to the form of the stove 2, so as to achieve the desired effect.
