Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, and more specifically to a piezoelectric plug valve. Background Art

[0002] In stoves or cookers that use gas as energy, piezoelectric plug valves are the most widely used valve body structure. The general structure of this type of plug valve includes a plug valve body, a plug valve stem and a plug valve core. For example, Chinese patent publication number CN117628261A discloses a plug valve and a stove, which relates to the field of gas stoves. The plug valve includes a pressure rod, an adjustment ring, a pressure plate, a child lock piece and an elastic member. The pressure plate has a first limit block and a second limit block. The pressure rod drives the child lock piece to rotate. The child lock piece has a first limit surface and a second limit surface. The plug valve has two states. In the first state, the first limit surface of the child lock piece abuts against the first limit block of the pressure plate, and the second limit surface abuts against the second limit block to achieve limit. In the second state, the first limit surface of the child lock piece abuts against the second limit block to achieve limit. The two states can be freely switched by pressing and rotating the pressure rod, and both can be locked. When rotating to the second state, the second limit block abuts against the first limit surface, so that the pressure rod can no longer be rotated, thereby giving the user a prompt that the plug valve has been rotated into the second state, so that it is convenient for the user to accurately control the adjustment of a specific firepower. However, the disadvantage is that the plug valve can only be ignited once per rotation of the button, and it is easy to fail to ignite or deflagration. For this reason, it is necessary to further improve the existing technology. Summary of the invention
