Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] It should be noted that the terms "first", "second", etc. in the description, claims and the above-mentioned drawings of the present utility model are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0041] An embodiment of the present utility model provides a gas stove, Figure 1 which is a schematic structural diagram of a gas stove provided by an embodiment of the present utility model, Figure 2 which is a schematic structural diagram of another gas stove provided by an embodiment of the present utility model. Refer to Figure 1 or Figure 2 , the gas stove includes: a burner 1, an air suction and contraction pipe 2, and a primary air adjustment structure 3; the gas inlet 21 of the air suction and contraction pipe 2 is connected to a gas nozzle 4, and the outlet 22 of the air suction and contraction pipe 2 is connected to the burner 1; the side wall of the air suction and contraction pipe 2 includes a through hole 21; one end of the primary air adjustment structure 3 can extend into the air suction and contraction pipe 2 through the through hole 21, and the length of the primary air adjustment structure 3 extending into the air suction and contraction pipe 2 is adjustable.

[0042] Exemplarily, the burner 1 may include: a burner head 11, a copper seat 12, and a burner body 13; one end of the burner head 11 is connected to the outlet of the air suction and contraction pipe 2, and the other end of the burner head 11 faces the fire outlet direction of the burner 1; along the fire outlet direction of the burner 1, the copper seat 12 is arranged on the burner head 11, and the burner body 13 is arranged on the copper seat 12. Gas and air enter the burner head 11 through the air suction and contraction pipe 2, and enter the burner body 13 through the burner head 11 and the copper seat 12 for mixed combustion.

[0043] Specifically, by setting the gas inlet 21 of the air suction and contraction pipe 2 to be connected to the gas nozzle 4, the gas ejected from the gas nozzle 4 can enter the air suction and contraction pipe 2 at a certain speed. The outlet 22 of the air suction and contraction pipe 2 is connected to the burner 1, so that the gas can flow to the burner 1 through the air suction and contraction pipe 2. Among them, the air suction and contraction pipe 2 may also be provided with an air inlet 23, and the air inlet 23 may be on the same side of the air suction and contraction pipe 2 as the gas inlet 21. Natural air can be entrained into the air suction and contraction pipe 2 through the air inlet 23, so that the air can enter the burner 1 through the air suction and contraction pipe 2, thereby enabling the gas and air to be mixed and burned.

[0044] At least a part of the primary air conditioning structure 3 is movable or telescopic. A through hole H0 can be provided on the side wall of the air suction and contraction pipe 2, and the size of the through hole H0 can be adapted to the movable or telescopic end of the primary air conditioning structure 3, so that the movable or telescopic end of the primary air conditioning structure 3 can pass through the through hole H0 and extend into the air suction and contraction pipe 2. After the primary air conditioning structure 3 extends into the air suction and contraction pipe 2 through the through hole H0, the extending direction of the part extending into the air suction and contraction pipe 2 is perpendicular to the extending direction of the air suction and contraction pipe 2, that is, perpendicular to the flowing direction of air and gas, so that the part of the primary air conditioning structure 3 extending into the air suction and contraction pipe 2 has a blocking effect on the gas and air flowing to the burner 1. And since the length of the primary air conditioning structure 3 extending into the air suction and contraction pipe 2 is adjustable, the blocking degree of the primary air conditioning structure 3 on the gas and air flowing to the burner 1 is adjustable. Therefore, by adjusting the length of the primary air conditioning structure 3 extending into the air suction and contraction pipe 2, the gas amount and air amount provided to the burner 1 can be adjusted, and the flame size can be adjusted. It can be understood that when one end of the primary air conditioning structure 3 extending into the air suction and contraction pipe 2 through the through hole H0 abuts against the side wall of the air suction and contraction pipe 2 (as Figure 2 shown), the blocking degree on the gas and air flowing to the burner 1 is the largest, so that the energy loss of the gas jet is the largest, and the primary air intake is the least. And when the primary air conditioning structure 3 does not extend into the air suction and contraction pipe 2 at the position of the through hole H0, or when the primary air conditioning structure 3 is outside the air suction and contraction pipe 2 (as Figure 1 shown), there is no blocking effect on the gas and air flowing to the burner 1, so that the energy loss of the gas jet is the smallest, and the primary air intake is the largest.

[0045] The gas stove provided by the embodiment of the present utility model realizes the adjustment of the flame size of the burner by providing that the side wall of the air suction and contraction pipe includes a through hole, so that the primary air conditioning structure can extend into the air suction and contraction pipe through the through hole, and by setting that the length of the primary air conditioning structure extending into the air suction and contraction pipe is adjustable, so that the energy loss degree of the gas jet is adjustable, and the intake amount of the primary air is adjustable, and the gas amount and air amount provided to the burner can be adjusted by adjusting the length of the primary air conditioning structure extending into the air suction and contraction pipe.

[0046] Optionally, Figure 3 is a schematic structural diagram of a primary air conditioning structure provided by an embodiment of the present utility model, as Figure 3As shown, the primary air conditioning structure 3 includes a drive motor 31 and a blocking structure 32; one end of the blocking structure 32 can extend into the suction contraction tube 2 through the through hole H0; the other end of the blocking structure 32 is in transmission connection with the drive motor 31; the blocking structure 32 moves along the first direction X or the second direction Y under the drive of the drive motor 31; the first direction X is the direction in which the blocking structure 32 faces the through hole H0, and the second direction Y is opposite to the first direction X.

[0047] Specifically, the drive motor 31 can serve as a power source for driving the movement of the blocking structure 32. When it rotates, it drives the blocking structure 32 to move along the first direction X or the second direction Y through the transmission shaft 311. In one embodiment, it can be set that when the drive motor 31 rotates forward, it drives the blocking structure 32 to move along the first direction X, and when the drive motor 31 rotates in reverse, it drives the blocking structure 32 to move along the second direction Y.

[0048] Optionally, referring to Figure 3 , the blocking structure 32 includes a driving member 321 and a plug 322; one end of the plug 322 is fixedly arranged on the driving member 321, and the other end of the plug 322 faces the through hole H0; the driving member 321 is also in transmission connection with the drive motor 31; the driving member 321 moves along the first direction X or the second direction Y under the drive of the drive motor 31.

[0049] Specifically, the blocking structure 32 can include two parts, a driving member 321 and a blocking structure 322. The driving member 321 and the plug 322 are fixed into an integral structure, so that on the one hand, the driving member 321 can play a role in supporting the plug 322, and on the other hand, it can drive the plug 322 to move under the drive of the drive motor 31.

[0050] Exemplarily, in one embodiment, the plug 322 is a cylindrical steel bar. Its diameter can be less than or equal to the diameter of the through hole H0 on the suction contraction tube 2, so that the plug 322 can pass through the through hole H0. It can be understood that the extending direction of the plug 322 is parallel to the first direction X and the second direction Y in which it can move, so that the plug 322 moves along its extending direction, so that the length of its extension into the suction contraction tube 2 is adjustable.

[0051] In one embodiment, the driving member 321 is a rectangular steel bar. Preferably, the diameter of the inscribed circle of the rectangular surface where the rectangular steel bar is fixedly connected to the plug 322 is greater than or equal to the diameter of the plug 322, so that the driving member 321 can stably carry the plug 322 and ensure the stability of the blocking structure 32.

[0052] In one embodiment, the driving member 321 includes a first side wall A1 extending along the first direction X; the first side wall A1 includes adjusting teeth B1; the transmission shaft 311 of the driving motor 31 includes driving teeth B2 arranged along the circumferential direction; the driving teeth B2 and the adjusting teeth B1 mesh with each other.

[0053] Specifically, setting the first side wall A1 can be understood as the side wall of the driving member 321 adjacent to the side surface where the plug is provided. When the driving member 321 is a rectangular steel bar, it can be understood that the driving member 321 includes four first side walls A1. At least one first side wall can be provided with adjusting teeth B1, and driving teeth B2 arranged along the circumferential direction are provided on the transmission shaft 311 of the driving motor 31. By setting the driving teeth B2 and the adjusting teeth B1 to mesh with each other, the transmission connection between the driving member 321 and the driving motor 31 can be realized, that is, the transmission connection between the blocking structure 32 and the driving motor 31 is realized. When the driving motor 31 rotates, its transmission shaft 311 rotates synchronously. Through the meshing driving teeth B2 and adjusting teeth B1, the angular displacement can be converted into a linear displacement, so that the driving member 321 can drive the plug 322 to move along the first direction X or the second direction Y, and the length of the plug 322 extending into the suction contraction tube 2 can be adjusted.

[0054] Exemplarily, only one first side wall A1 of the driving member 321 is shown with adjusting teeth B1 in the figure. It can be understood that in other feasible embodiments of the present invention, the other three first side walls A1 can be provided with adjusting teeth B1, which is convenient for the transmission installation between the blocking structure 32 and the driving motor 31. Or two of the first side walls A1 can be provided with adjusting teeth B1, or three of the first side walls A1 can be provided with adjusting teeth B1. The present invention does not make specific limitations on this.

[0055] In one embodiment, the tooth grooves of the adjusting teeth B1 extend along the axial direction of the transmission shaft 311 and are arranged in the first direction X; the tooth grooves of the driving teeth B2 extend along the axial direction of the transmission shaft 311 and are arranged along the circumferential direction of the transmission shaft 311; the axial direction of the transmission shaft 311 is perpendicular to the first direction X. With such a setting, during the rotation of the transmission shaft 311, at least one tooth of the adjusting teeth B1 is always inserted into the tooth groove of the driving teeth B2, and at least one tooth of the driving teeth B2 is always inserted into the tooth groove of the adjusting teeth B1, realizing the mutual meshing of the driving teeth B2 and the adjusting teeth B1.

[0056] Exemplarily, the axial direction of the transmission shaft 311 is perpendicular to the first direction X. In this way, during the rotation of the transmission shaft 311, the angular displacement can be converted into a linear displacement along the first direction X or the second direction Y, and the driving member 321 can be driven to move along the first direction X or the second direction Y.

[0057] In one embodiment, the diameter of the through hole H0 is smaller than the diameter of the air suction contraction tube 2. In this way, the diameter of the part of the primary air conditioning structure 3 extending into the air suction contraction tube 2 (i.e., the diameter of the plug 322) is smaller than the diameter of the air suction contraction tube 2. When the plug 322 of the primary air conditioning structure 3 extends into the air suction contraction tube 2 and abuts against the inner wall on one side of the air suction contraction tube 2 (the inner wall opposite to the through hole H0), there is a space between the plug 322 and the inner walls on both sides of the air suction contraction tube 2, and the passage in the air suction contraction tube 2 will not be completely blocked, ensuring that air can always enter. In this way, the air demand during the small fire of the burner 1 can be ensured, and it is also beneficial for air to enter when the gas stove is turned off, so that the residual gas inside can escape by inhaling air.

[0058] The above specific embodiments do not limit the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
