As shown in fig. 1 to 3, the nozzle assembly for a gas range of the present embodiment includes a nozzle body 10 and a gas amount adjusting structure. The nozzle body 10 has a gas passage 11. The gas amount adjusting structure includes an adjusting body 20 and a driving assembly. Wherein the adjustment body 20 is rotatably arranged in the gas channel 11. The adjustment body 20 has a first nozzle hole 21 and a second nozzle hole 22 provided therethrough. The first nozzle hole 21 and the second nozzle hole 22 have different pore sizes. The center line of the first nozzle hole 21 is perpendicular to the center line of the second nozzle hole 22. The driving assembly drives the adjusting body 20 to rotate so that one of the first spray hole 21 and the second spray hole 22 is communicated with the gas channel 11, and the other of the first spray hole 21 and the second spray hole 22 is blocked by the channel wall of the gas channel 11.
When the nozzle assembly for a gas range of the present embodiment is applied and the adjusting body 20 is rotated to a position, the first nozzle hole 21 is communicated with the gas passage 11, the second nozzle hole 22 is blocked by the passage wall of the gas passage 11, and at this time, the gas is ejected through the first nozzle hole 21 and introduced into the burner. When the adjusting body 20 rotates to another position, the second spray hole 22 is communicated with the gas channel 11, the first spray hole 21 is blocked by the channel wall of the gas channel 11, and at the moment, the gas is sprayed out through the second spray hole 22 and introduced into the burner. The two positions to which the regulating body 20 is rotated may correspond to two combustion states or to two air sources, respectively.
For example, the aperture of the second spray hole 22 is larger than the aperture of the first spray hole 21, when the gas stove needs to be in a quick-frying state, the adjusting body 20 is rotated to a position where the second spray hole 22 is communicated with the gas channel 11, the gas quantity is increased, and when the gas stove needs to be in a normal combustion state, the adjusting body 20 is rotated to a position where the first spray hole 21 is communicated with the gas channel 11, and the gas quantity is reduced; or when the gas stove needs to be filled with natural gas, the adjusting body 20 is rotated to a position where the second spray hole 22 is communicated with the gas channel 11, and when the gas stove needs to be filled with liquefied gas, the adjusting body 20 is rotated to a position where the first spray hole 21 is communicated with the gas channel 11. The structure can switch the first spray hole 21 or the second spray hole 22 according to different combustion states or different gas sources, has strong adaptability and is more flexible to use, so that the gas stove has better cooking effect.
In addition, the center line of the first spray hole 21 is perpendicular to the center line of the second spray hole 22, so that when one of the first spray hole 21 and the second spray hole 22 is aligned to the gas channel 11, the other can be blocked by the channel wall of the gas channel 11, the occurrence of gas leakage is effectively prevented, and the use is safe and reliable. Meanwhile, the first spray hole 21 and the second spray hole 22 can be mutually switched by rotating the adjusting body 20 by 90 degrees, so that the operation is more convenient.
Note that, the relationship between the aperture of the second nozzle hole 22 and the aperture of the first nozzle hole 21 is not limited thereto, and in other embodiments, the aperture of the second nozzle hole may be smaller than the aperture of the first nozzle hole; in addition, the two corresponding operation modes of the gas stove when the adjusting body rotates to the two positions are not limited to the two operation modes, and in other embodiments, the two positions to which the adjusting body rotates may correspond to the two other operation modes requiring different apertures of the nozzle holes.
As shown in fig. 2, 3 and 5, in the nozzle assembly of the present embodiment, the gas passage 11 includes an intake section 111 and a gas buffer section 112. The gas buffer section 112 is located between the gas inlet section 111 and the conditioning body 20. That is, the fuel gas from the inlet of the fuel gas channel 11 sequentially passes through the gas inlet section 111 and the gas buffer section 112, reaches the adjustment body 20, and is ejected from the first nozzle 21 or the second nozzle 22 of the adjustment body 20. In the present embodiment, the first nozzle hole 21 is in communication with the gas passage 11, and the center line of the first nozzle hole 21 is collinear with the center line of the gas passage 11. The flow area of the intake section 111 gradually decreases in the flow direction of the fuel gas. During the gas passing through the inlet section 111, the gas flow is accelerated, and the velocity of the gas flow is maximized when the gas flow reaches the end of the inlet section 111, after which the gas flow enters the gas buffer section 112. Since the flow area of the gas buffer section 112 is equal to and remains unchanged from the flow area of the end of the gas inlet section 111, the gas buffer section 112 can temporarily buffer the gas flow. The amount of fuel gas buffered by the gas buffer section 112 entering the first nozzle hole 21 per unit time is reduced, so that the fuel gas can be further prevented from leaking from the second nozzle hole 22. When the second nozzle 22 is communicated with the gas channel 11, the flow process of the gas is the same as that when the first nozzle 21 is communicated with the gas channel 11, and will not be described herein. In the present embodiment, the length of the gas cushion section 112 in the flow direction of the fuel gas is 0.3mm or more. The aperture of the end of the air inlet section 111 is 4 to 6mm.
As shown in fig. 2 to 4, in the nozzle assembly of the present embodiment, the side surface of the nozzle body 10 is provided with a circle of side holes, each of which communicates with the gas passage 11 and is located downstream of the adjustment body 20. After the fuel gas is sprayed out from the first spray hole 21 or the second spray hole 22, a small amount of air is introduced from the side hole at the moment due to the high speed of the fuel gas flow, so that the proportion of air in the fuel gas can be increased to a certain extent, and the fuel gas can be fully combusted in the subsequent combustor.
As shown in fig. 1 to 6, in the nozzle assembly of the present embodiment, the driving assembly includes a rotating lever 31 and a driving disk 32. Wherein, the first end of the rotating rod 31 is inserted into the gas channel 11 from the side of the nozzle body 10 and fixedly connected with the adjusting body 20. The driving disk 32 is fixedly connected to the second end of the rotation lever 31. When the driving disc 32 rotates, the adjusting body 20 can be driven to rotate by the rotating rod 31. The driving disc 32 and the rotating rod 31 have simple structures, are convenient to process and manufacture, and are convenient to assemble. Specifically, a through hole is formed in the side surface of the nozzle body 10, the through hole penetrates into the gas channel 11, when the rotating rod 31 is inserted into the through hole, the circumferential side wall of the rotating rod 31 and the inner wall of the through hole are mutually attached, so that the real-time attachment state between the rotating rod 31 and the inner wall of the through hole in the rotating process can be ensured, and the occurrence of the gas leakage phenomenon can be prevented. In the present embodiment, the rotating lever 31 is integrally formed with the regulating body 20, which facilitates assembly. Of course, the connection manner of the rotating rod 31 and the adjusting body 20 is not limited thereto, and in other embodiments, the rotating rod and the adjusting body may be two independent parts.
As shown in fig. 2, 4 and 6, in the nozzle assembly of the present embodiment, the drive plate 32 is provided with a stopper pin 321. The side of the nozzle body 10 is provided with a limit groove 12 which is matched with the limit pin 321. The above-mentioned stop pin 321 and the stop slot 12 cooperate to define the rotation track of the driving disc 32 during the rotation of the driving disc 32, so as to improve the reliability of the movement of the driving disc 32. In this embodiment, the limiting groove 12 is arc-shaped, and the arc angle of the arc-shaped limiting groove 12 is 90 °. The above-mentioned limit slot 12 cooperates with the limit pin 321 to precisely define the rotation angle of the driving disc 32, so that the driving disc 32 rotates within a 90 ° range, and the switching between the first nozzle 21 and the second nozzle 22 is more accurate. Of course, the shape of the limiting groove 12 is not limited thereto, and in other embodiments not shown in the drawings, the limiting groove may be annular, which may only serve to improve the reliability of the movement of the driving disk.
As shown in fig. 1, 2, and 6 to 7, in the nozzle assembly of the present embodiment, the driving assembly further includes a link 33 and a driver 34. Wherein a first end of the link 33 is rotatably connected to the drive plate 32. The driver 34 has a telescopic rod 341, and the second end of the link 33 is rotatably connected to the telescopic rod 341. Specifically, the driver 34 may extend or retract the telescopic rod 341. When the telescopic rod 341 is extended, the second end of the connecting rod 33 is pushed, so that the first end of the connecting rod 33 drives the driving disc 32 to rotate anticlockwise, and after the driving disc 32 rotates in place, the first spray hole 21 is communicated with the gas channel 11. When the telescopic rod 341 is retracted, the second end of the connecting rod 33 is pulled, so that the first end of the connecting rod 33 drives the driving disc 32 to rotate clockwise, and after the driving disc 32 rotates in place, the second spray hole 22 is communicated with the gas channel 11. The driving assembly can drive the adjusting body 20 to rotate, and the motion fit is reliable. In this embodiment, the driver 34 is an electromagnetic valve, and the telescopic rod 341 can be controlled to retract or extend by the electromagnetic valve being attracted or sprung, so that the operation is convenient and the reliability is high. Of course, the specific structure of the driver 34 is not limited thereto, and in other embodiments, the driver may be a motor, a hydraulic cylinder, or the like.
As shown in fig. 1, 7 and 8, in the nozzle assembly of the present embodiment, the driving assembly further includes a support 35. The support 35 is rotatably provided at the middle of the link 33. The support 35 can form a pivot point for the rotation of the link 33, ensuring the effective movement of the driver 34, the link 33 and the driving disk 32. In the present embodiment, two long holes are provided at both ends of the link 33, a connecting hole is provided at the middle of the link 33, and the support 35 is rotatably fitted with the connecting hole. The telescopic rod 341 of the driver 34 is fitted with one elongated hole, and the upper surface of the driving plate 32 is provided with a connection pin which is fitted with the other elongated hole, thereby achieving rotatable connection of the link 33 with the driving plate 32 and rotatable connection of the link 33 with the telescopic rod 341. Of course, the connection manner of the link 33 to the driving plate 32 and the telescopic rod 341 is not limited thereto, and in other embodiments not shown in the drawings, the link may be connected to the telescopic rod and the driving plate through a rotation shaft.
It should be noted that, the structure of the driving assembly is not limited to the above structure, and in other embodiments, the driving assembly may be a motor, and a motor shaft of the motor extends into the gas channel to be in driving connection with the adjusting body; alternatively, the driving assembly only comprises a rotating rod and a driving disc, and the driving disc is manually rotated, so that the adjusting body is driven to rotate.
As shown in fig. 8, the present application further provides a gas stove, and an embodiment of the gas stove according to the present application includes a burner and a nozzle assembly disposed on the burner, where the nozzle assembly is the nozzle assembly described above.

The burner also comprises a big fire injection pipe communicated with the big fire gas mixing cavity and a small fire injection pipe communicated with the small fire gas mixing cavity. In this embodiment, the gas passage 11 of the nozzle assembly communicates with the large fire injection duct. When the regulating body 20 is rotated, the first spray hole 21 and the second spray hole 22 are selectively communicated with the gas passage 11, so that the gas-exchanging stove is in a stir-frying state or a normal combustion state. In this embodiment, the aperture of the second spray hole 22 is larger than the aperture of the first spray hole 21, when the gas stove needs to be in the quick-frying state, the adjusting body 20 is rotated to the position where the second spray hole 22 is communicated with the gas channel 11, the gas amount is increased, when the gas stove needs to be in the normal combustion state, the adjusting body 20 is rotated to the position where the first spray hole 21 is communicated with the gas channel 11, and the gas amount is reduced.
