Further, the gas stove further comprises a control board connected with the gas valve and a display module or a sound module connected with the control board, wherein a detection circuit is arranged in the control board, two ends of the detection circuit are respectively connected with the first conductive sheet and the second conductive sheet, at least one of the first conductive sheet and the second conductive sheet is in a non-contact conduction state with the positioning needle, the control board sends out a signal, and the display module and the sound module are triggered. The gas valve is started when the detection circuit is switched on, the outer ring fire cover is detected to be not put in place, the display module and the sound module are started, and a user is prompted that the fire cover is not put in place.
Further, the outer end surface of the first conductive sheet is curved to have elasticity.
The insulating sleeve and the positioning needle are preferably assembled as follows: the lower end of the insulating sleeve is provided with an assembly groove, and the upper end of the positioning needle is inserted into the assembly groove.
Preferably, the lower end of the positioning needle is pointed.
Further, the fire cover comprises an outer ring fire cover and a central fire cover, and the insulating sleeve is arranged on the inner side of the outer ring fire cover.
Compared with the prior art, the invention has the advantages that: when the fire cover is not put in place, the positioning needle does not connect the first conducting strip and the second conducting strip to form an open circuit, and when the valve body is pressed down to perform ignition action, the ignition needle does not ignite, so that safety problems of fire cover burning deformation, deflagration and the like caused by the fact that the fire cover is not put in place and a stove is used by a user can be avoided.
