By means of the arrangement of the curved transition, mixed gases can be guided into the flow guide cavity (130) and the gas supply cavity (140), such that a gas path inside the gas burner is unobstructed.
A gas valve (100) and a cooktop, the gas valve (100) comprising: an outer casing (10), a mounting hole (101) being provided on the outer casing (10), and a limiting structure (15) being provided around the outer end of the mounting hole (101); a valve core (20), which is rotatably provided in the outer casing (10) so as to adjust an opening degree; a valve stem (30), which is connected to the outer casing (10) in such a manner of being rotatable in the circumferential direction and movable in the axial direction, a handle portion of the valve stem (30) extending out of the outer casing (10) from the outer end of the mounting hole (101) and being provided with a positioning member (37), and the positioning member (37) being adapted to be limited by the limiting structure (15) so as to limit the rotation angle of the valve stem (30); and a positioning block (40), wherein the positioning block (40) is provided in the outer casing (10), the positioning block (40) has a locked position and an unlocked position in the axial direction, the positioning block (40) is locked in the locked position, can rotate in the unlocked position, and is adapted to drive the valve core (20), and the positioning block (40) is fixed at a relative position in the circumferential direction with respect to the valve stem (30) and is adapted to be driven by the valve stem (30).

A gas valve and a hob, the gas valve comprising: a housing (10), a valve core (20), a valve stem (30), and a positioning block (40). The valve core (20) is rotatably arranged in the housing (10) to adjust the degree of opening. The valve stem (30) is rotatably connected to the housing (10) in the circumferential direction and is movably connected to the housing (10) in the axial direction, and the valve stem (30) is adapted to trigger a gas valve body (70). The positioning block (40) has a locking position and an unlocking position in the axial direction; at the locking position, the positioning block (40) is locked, and at the unlocking position, the positioning block can rotate and is adapted to drive the valve core (20); the positioning block (40) and the valve stem (30) can move relatively in the axial direction, and are fixed relatively in the circumferential direction; the positioning block (40) is adapted to be driven by the valve stem (30). According to the gas valve, the driving structure of the gas valve body is separated from the driving structure of the valve core, thereby avoiding flameout after the valve stem is loosened.
