[0060] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0061] The utility model provides a gas cooker, which includes a burner and a gas valve 100. The outer ring gas channel and the inner ring burner channel of the burner are respectively connected to the gas valve 100, so that the user can adjust the gas flow rate delivered to the inner ring gas channel and the outer ring gas channel by rotating the knob of the gas valve 100, thereby achieving the purpose of adjusting the firepower.

[0062] like Figure 1, which is a schematic diagram of the structure of the gas valve 100 in this embodiment. As can be seen from the figure, the first gas outlet 101 and the second gas outlet 102 of the gas valve 100 are used to connect to the inner ring gas channel and the outer ring gas channel of the burner, respectively. The user rotates the gas knob located on the top of the gas valve 100 to adjust the gas flow rate delivered to the burner.

[0063] Specifically, such as Figure 2 As shown, in order to achieve the purpose of adjusting the gas flow of the first gas outlet 101 and the second gas outlet 102 respectively, in this embodiment, the gas valve 100 includes a first gas knob 1, a second gas knob 2, a first valve stem 3, a second valve stem 4, a first closure 5 and a second closure 6 which are coaxially arranged, wherein the first closure 5 is arranged above the second closure 6, the first valve stem 3 is sleeved on the outer circumference of the second valve stem 4, the lower end of the first valve stem 3 is connected to the first closure 5, the lower end of the second valve stem 4 passes through the first closure 5 and is connected to the second closure 6, the first gas knob 1 is connected to the upper end of the first valve stem 3 and is used to drive the first closure 5 to rotate (see Figure 3 ), to achieve the purpose of adjusting the gas flow of the first gas outlet 101. The second gas knob 2 is connected to the upper end of the second valve stem 4 and is used to drive the second valve 6 to rotate (see Figure 4 ), to achieve the purpose of adjusting the gas flow of the first gas outlet 101.

[0064] The gas valve 100 is provided with a first gas knob 1, a second gas knob 2, a first valve stem 3, a second valve stem 4, a first closer 5 and a second closer 6. The first gas knob 1 drives the first closer 5 to rotate through the first valve stem 3, and the second gas knob 2 drives the second closer 6 to rotate through the second valve stem 4. The two knobs respectively control the rotation of the two closers, thereby providing more gas distribution solutions, so that more fire power combinations of burners connected to the gas valve 100 can be achieved, meeting the increasingly diverse cooking needs of users.

[0065] At the same time, the first valve stem 3 and the second valve stem 4 are arranged coaxially, and the first shutter 5 and the second shutter 6 are arranged up and down, so that the space occupied by the two shutters and the positions of the two gas knobs are the same as those of the single-shut gas valve 100 of the current prior art. Therefore, the space occupied by the structural improvement can be reduced, and the compatibility is higher.

[0066] Specifically, such as Figure 2 and Figure 3 As shown, a first connecting rod 31 is provided at the lower end of the first valve stem 3. The first connecting rod 31 extends outward along the horizontal direction A and is connected to the upper end of the first closure 5. By arranging the first connecting rod 31 at the lower end of the first valve stem 3 to extend horizontally outward and connect the upper end of the first closure 5, a reliable connection between the first valve stem 3 and the first closure 5 is achieved.

[0067] like Figure 2 As shown, the gas valve 100 further includes a valve body 71 and a valve body cover plate 72. The valve body cover plate 72 covers the upper surface of the valve body 71 and is used to accommodate the first closure 5 and the second closure 6. Figure 5 and Figure 6 As shown, a first shift plate 81 is provided on the lower surface of the valve body cover plate 72. The upper surface of the first connecting rod 31 is configured to engage with a shift groove on the upper surface of the first shift plate 81, thereby enabling the first gas knob 1 to have a shift function, facilitating precise flame adjustment for the user. Therefore, by engaging the first connecting rod 31 on the first valve stem 3, which is used to connect to the first closer 5, with the shift groove on the first shift plate 81, and utilizing the first connecting rod 31 of the first valve stem 3 to implement the shift function, the structure of the first valve stem 3 and the first closer 5 can be made more compact.

[0068] like Figure 2 and Figure 4 As shown, in this embodiment, the first gas knob 1 is positioned above the second gas knob 2, and the upper end of the first valve stem 3 passes through the second gas knob 2 and connects to the first gas knob 1. In this structural layout, to allow the second gas knob 2, located below, to connect with the second valve stem 4, which is sleeved within the first valve stem 3, a hollow portion 32 is provided on the side of the first valve stem 3 adjacent to the second gas knob 2. This allows the second gas knob 2 to connect to the upper end of the second valve stem 4 through the hollow portion. By providing a hollow portion on the first valve stem 3 for connecting the second gas knob 2 to the second valve stem 4, the second gas knob 2 can connect to the second valve stem 4 within the first valve stem 3 even when positioned below the first gas knob 1, allowing the second gas knob 2 to be positioned below the first gas knob 1. Specifically, since the rotation angle of the second gas knob 2 is generally greater than or equal to 180° and less than 360°, a fan-shaped hollow portion 32 is provided on the surface of the first valve stem 3 so as to be greater than the rotation angle of the second gas knob 2 , so that the connection between the second gas knob 2 and the second valve stem 4 is not hindered by the second gas knob 2 .

[0069] Specifically, such as Figure 4 As shown, the lower end of the second gas knob 2 has a second connecting rod 21, which extends horizontally along a direction A into the hollow portion and connects to the upper end of the second valve stem 4. The gas valve 100 also includes a second shift plate 82, which is horizontally positioned below the hollow portion. The lower surface of the second connecting rod 21 is designed to engage with a shift groove on the upper surface of the second shift plate 82. This structural arrangement allows the second connecting rod 21 of the second gas knob 2 to achieve a shift function when the user presses the knob to disengage the child lock. This is achieved by engaging the lower surface of the second connecting rod 21 on the second gas knob 2, which is used to connect to the second valve stem 4, with the shift groove on the second shift plate 82. This makes the structure of the second valve stem 4 and the second closer 6 more compact.

[0070] The gas valve 100 also includes a connecting mechanism, which is positioned between the first and second gas knobs 1 and 2 and can switch between a first and second state. Specifically, when the connecting mechanism is in the first state, the first and second gas knobs 1 and 2 rotate synchronously; when the connecting mechanism is in the second state, the first and second gas knobs 1 and 2 rotate independently. By providing a connecting mechanism that allows the first and second gas knobs 1 and 2 to rotate synchronously or independently, the user is provided with more operating options to meet their diverse operational needs.

[0071] like Figure 7a and Figure 7b As shown, in this embodiment, a relatively simple and compact linkage scheme for the first gas knob 1 and the second gas knob 2 is provided. The connection mechanism specifically includes: a protrusion 91 formed on the upper surface of the second gas knob 2, and a recess 92 formed on the lower surface of the first gas knob 1. The position and shape of the protrusion 91 match the position and shape of the recess 92. In addition, the portion of the first gas knob 1 can move up and down relative to the second gas knob 2 along the vertical direction B (see FIG. Figure 2 When this portion of the first gas knob 1 moves upward, the protrusion 91 and the recess 92 disengage from each other, allowing the first gas knob 1 and the second gas knob 2 to rotate independently. When this portion of the first gas knob 1 moves downward, the protrusion 91 and the recess 92 engage with each other, allowing the first gas knob 1 and the second gas knob 2 to rotate synchronously.

[0072] In this embodiment, the first gas knob 1 is an outer ring gas knob, the first closer 5 is used to control the gas flow of the first gas outlet 101, the second gas knob 2 is an inner ring gas knob, and the second closer 6 is used to control the gas flow of the second gas outlet 102. By setting the first gas knob 1, located at the top, as an outer ring gas knob and the second gas knob 2, located at the bottom, as an inner ring gas knob, the user's operating habits are matched.

[0073] In this layout, the diameter of the first gas knob 1 is smaller than that of the second gas knob 2 , so that the first gas knob 1 located above does not hinder the user from operating the second gas knob 2 below.

[0074] In addition, in this embodiment, the first closure 5 and the second closure 6 both adopt a double closure structure, which can reduce the difficulty of processing while improving the structural accuracy of each closure, meeting the demand for precise control of gas.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
