[0032] The following embodiments are used to illustrate the utility model, but the utility model is not limited by these embodiments. The specific embodiments of the utility model are modified or some technical features are replaced equivalently without departing from the spirit of the utility model scheme, which should be covered in the technical scheme range claimed by the utility model.

[0033] Please refer to Figures 1-7 , the utility model provides a knob valve, including knob valve cover 1, valve stem 2 and valve core structure. Valve stem 2 upper end and knob valve cover 1 fixed connection. Valve core structure includes valve seat 3 and the valve core of setting on valve seat 3, and the lower end of valve stem 2 is inserted with valve core.

[0034] The knob valve provided by the utility model, by the upper end of valve stem 2 is set as with knob valve cover 1 fixed connection, the lower end of valve stem 2 is inserted with valve core, so that when knob valve cover 1 is pulled out, valve stem 2 can also be pulled out from valve core, compared with the upper end of valve stem 2 in the knob valve of prior art is set as with knob valve cover 1 insertion mode, so that the upper end of valve stem 2 still protrudes from the upper of panel 52 of gas stove even after knob valve cover 1 is pulled out, the user is still difficult to clean the dirt around valve stem 2 mode, the valve stem 2 in the embodiment can be pulled out with knob valve cover 1, will not protrude in the upper of panel 52, it is beneficial to the user to clean panel 52 completely, and the structure is simple, without the substantial modification of original knob valve cover 1, valve stem 2 and valve core, and the cost is lower.

[0035] Optionally, it also includes a seal 4, which is sleeved on the valve stem 2 and disposed between the knob valve cover 1 and the valve core structure. When the knob valve is installed on the gas stove, the seal 4 is located between the valve stem 2 and the panel 52 of the gas stove, and is used to seal the gap between the valve stem 2 and the panel 52, reducing the amount of dirt that falls into the bottom shell 51 of the gas stove through the gap between the valve stem 2 and the panel 52.

[0036] Optionally, a first through hole 40 is provided in the middle of the seal 4, and the valve stem 2 passes through the first through hole 40. A sealing membrane 41 is provided in the first through hole 40, and a cross opening 410 is provided on the sealing membrane 41. The valve stem 2 can open the cross opening 410 so that the sealing membrane 41 is close to the outer periphery of the valve stem 2. On the one hand, it can achieve further sealing between the valve stem 2 and the panel 52. On the other hand, when the valve stem 2 is pulled out from the valve core, the sealing membrane 41 can automatically recover to block the first through hole 40, reducing the amount of dirt entering the bottom shell 51 through the first through hole 40 after the valve stem 2 is pulled out.

[0037] Optionally, the upper end of the seal 4 is provided with an outwardly extending upper flange 42, and the lower end of the seal 4 is provided with an outwardly extending lower flange 43. When the knob valve is installed on the gas stove, the upper flange 42 is located on the upper side of the panel 52 and abuts against the upper side of the panel 52, and the lower flange 43 is located on the lower side of the panel 52 and abuts against the lower side of the panel 52. This allows the seal 4 to be installed on the panel 52 and improves the sealing effect.

[0038] Optionally, the valve seat 3 includes a valve seat body 31 and a limiting member 32 disposed within the valve seat body 31. The valve seat body 31 has a second through hole 310, and the limiting member 32 has a limiting through hole 320. The lower end of the valve stem 2 is provided with a limiting block 21 corresponding to the limiting through hole 320. The valve stem 2 passes through the second through hole 310, and the limiting block 21 passes through the limiting through hole 320 and is inserted into the valve core. By setting the limiting through hole 320 and the limiting block 21 for insertion, the insertion position of the limiting block 21 is limited, thereby achieving the effect of preventing the valve stem 2 from being fooled into insertion or removal.

[0039] Optionally, both the limiting through hole 320 and the limiting block 21 are in the shape of a straight line, which is simple in structure.

[0040] Optionally, the upper end of the valve stem 2 is fixedly connected to the knob valve cover 1 by threads, ensuring a reliable connection.

[0041] Another aspect of this utility model provides a gas stove, including a bottom shell 51 and a panel 52 disposed on the upper side of the bottom shell 51. The bottom shell 51 and the panel 52 form a receiving cavity 100. The stove also includes the aforementioned rotary valve, with the valve core structure installed in the receiving cavity 100 and the upper end of the valve stem 2 extending above the panel 52.

[0042] The above merely describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are all within the protection scope of the present application.
