The gas stove is widely applied to daily families as a common kitchen ware. The gas stove comprises a burner, and ventilation fire holes are formed in the burner. When the burner is in use, fuel is sprayed out through the ventilation fire holes and is in contact with the outside air for combustion.

In the related art, fuel ejected from the ventilation fire hole can only contact with surrounding air during operation of the burner. With the progress of combustion, the content of air which can be contacted with the fuel becomes small, so that the fuel can not be fully combusted, harmful gas is generated, and the air quality and the human health are affected.

Based thereon, embodiments of the present application provide a cooktop that may include a burner. As shown in fig. 1, fig. 1 is a schematic structural diagram of a burner 100 according to an embodiment of the present application, and the burner 100 may include a burner 10 and a fire cover assembly 20.

As shown in fig. 2, fig. 2 is a schematic structural diagram of a burner 10 according to an embodiment of the present application, and a gas mixing chamber 101 is formed inside the burner 10. The gas mixing chamber 101 may be used to store a mixture of gas and air. It will be appreciated that, as shown in fig. 2, the burner 10 is provided with a gas mixture inlet 11 and a gas mixture outlet 12 communicating with the above-described gas mixture chamber 101, so that the mixture gas flows in and out.

As shown in fig. 3, fig. 3 is a schematic view of the burner 100 shown in fig. 1 at another angle, and the burner 100 may further include an ejector tube 30. One end of the injection pipe 30 is communicated with a gas mixing chamber 101 (fig. 2) of the burner 10, and the other end of the injection pipe 30 can be connected with a gas pipe. The gas may enter the mixing chamber 101 (fig. 2) of the burner 10 through the injector tube 30.

With continued reference to FIG. 3, the end of the eductor 30 remote from the burner 10 may be provided with a nozzle 301. In the process that the fuel gas enters the injection pipe 30 through the nozzle 301, surrounding air can be driven to be injected into the injection pipe 30 along with the fuel gas, so that the fuel gas and primary air are mixed.

It will be appreciated that the end of the ejector tube 30 connected to the burner 10 may be provided with an opening so that the ejector tube 30 communicates with the air mixing inlet 11 of the burner 10. Thus, the mixed gas in the injection pipe 30 can enter the mixed gas chamber 101 through the mixed gas inlet 11.

As shown in fig. 4, fig. 4 is a schematic view of a part of the structure of the burner 100 according to the embodiment of the present application, where the fire cover assembly 20 is disposed on the burner 10, and a gas-dividing chamber 201 is formed. Wherein the gas separation chamber 201 communicates with the gas mixing chamber 101 (fig. 2). Thus, the mixed gas in the mixed gas chamber 101 can enter the gas separation chamber 201.

Meanwhile, as shown in fig. 1, a ventilation fire hole 202 communicating with a gas separation chamber 201 (fig. 4) may be formed in the fire cover assembly 20. The mixed gas in the gas separation chamber 201 can be sprayed out through the ventilation fire holes 202 and ignited, and the gas is combusted under the cooperation of external air after the ignition.

Wherein, fire cover assembly 20 can be rotatably connected with burner 10. In this way, the burner 100 can rotate relative to the burner 10 during the combustion of the fuel gas, and the fuel gas can better contact with the surrounding air, thereby improving the combustion efficiency of the fuel gas.

Wherein the fire cover assembly 20 can rotate relative to the burner under the action of the air flow in the ventilation fire hole 202. Therefore, in the use process of the burner 100, the fire cover assembly 20 can rotate relative to the burner 10, the mixed gas sprayed from the ventilation fire holes 202 can be fully contacted with air, the combustion is more complete, the combustion efficiency is improved, and the content of harmful gas generated in the combustion process is reduced.

In order to enable the fire cover assembly 20 and the burner 10 to rotate relatively, the line along which the ventilation fire hole 202 extends may be different from the line along which the rotation axis of the fire cover assembly 20 is located, so that the fire cover assembly 20 moves relative to the burner 10 under the driving of the airflow in the ventilation fire hole 202. In this way, the reaction force of the air flow in the ventilation fire hole 202 to the fire cover assembly 20 can be decomposed into a force pushing the fire cover assembly 20 to rotate, thereby driving the fire cover assembly 20 to rotate relative to the burner 10.

Illustratively, as shown in fig. 5, fig. 5 is a velocity exploded view of the vent fire holes applied to the fire cover assembly, L representing the axis of rotation of the fire cover assembly, and plane S representing the plane of rotation of the fire cover assembly. V0 represents the speed at which the vent fire holes are applied to the fire cover assembly.

As can be seen from fig. 5, V0 is inclined with respect to the plane S, and is not located in the plane S, V0 can be decomposed into a component velocity V1 parallel to the plane S, v1=v0×cos θ1. On the basis of V1, V1 can be decomposed into a radial velocity V2 of the rotation axis, and a circumferential velocity V3. V3=v1×cos θ2. Wherein V3 is the rotational speed that the vent fire hole imparts to the fire cover assembly.

Thus, in the burner 100 provided in the embodiment of the present application, since the gas separation chamber 201 of the fire cover assembly 20 is communicated with the gas mixing chamber 101 of the burner 10, the mixed gas of the fuel gas and the primary air can enter the gas separation chamber 201 through the gas mixing chamber 101 and be ejected from the ventilation fire hole 202 on the fire cover assembly 20 for combustion. Because the straight line of the extending direction of the ventilation fire hole 202 and the straight line of the rotation axis of the fire cover assembly 20 are different, the reaction force of the airflow in the ventilation fire hole 202 driving the fire cover assembly 20 can be decomposed into a force pushing the fire cover assembly 20 to rotate, so as to drive the fire cover assembly 20 to rotate relatively. Thus, in the use process of the burner 100, the fire cover assembly 20 can rotate relative to the burner 10, and the mixed gas sprayed from the ventilation fire holes 202 can be fully contacted with air, so that the burner is more fully combusted, the combustion efficiency is improved, and the content of harmful gas generated in the combustion process is reduced.

As shown in fig. 1, the fire cover assembly 20 may include a distributor 21 and a fire cover 24. As shown in fig. 4, the distributor 21 may be rotatably connected to the burner 10, and the distributor 21 is formed with a distribution chamber 201. A fire cover 24 (fig. 1) is provided to cover the distributor chamber 201 and is connected to the distributor 21. The fire cover 24 is provided with ventilation fire holes 202 (fig. 1) which are communicated with the gas separation chamber 201.

It can be appreciated that the straight line of the extending direction of the ventilation fire hole 202 is different from the straight line of the rotation axis of the distributor 21, so that the distributor 21 rotates relative to the burner 10 under the driving of the air flow in the ventilation fire hole 202.

Therefore, the distributor 21 and the fire cover 24 can be driven to rotate relative to the burner by the air flow in the ventilation fire hole 202 on the fire cover 24, and the mixed gas sprayed out of the ventilation fire hole 202 can be fully contacted with air, so that the combustion is more complete, the combustion efficiency is improved, and the content of harmful gas generated in the combustion process is reduced.

It will be appreciated that the burner 10 may be directly or indirectly rotatably coupled to the distributor 21. In some embodiments, as shown in FIG. 1, the combustor 100 may also include a connection assembly 40. The connection assembly 40 is located between the distributor 21 and the burner 10 and is connected to the burner 10 and the distributor 21. The burner 10 and the distributor 21 may be rotatably connected by a connection assembly 40.

Through setting up coupling assembling 40, the rotation connection between furnace end 10 and the distributor 21 can be realized through coupling assembling 40 to need not to set up rotating-structure on furnace end 10 and distributor 21, simplified the structural design of furnace end 10 and distributor 21.

Of course, in other embodiments, the burner 10 and distributor 21 may be directly rotatably coupled. In this case, the above-mentioned connection assembly 40 is not required between the burner 10 and the distributor 21, and the overall structure of the burner 100 is relatively simple.

In some embodiments, as shown in fig. 6, fig. 6 is a schematic structural diagram of a connection assembly 40 according to an embodiment of the present application, where the connection assembly 40 may include a first connection member 41, a second connection member 42, and a plurality of balls 43.

The ball 43 may be clamped between the first connector 41 and the second connector 42, and is in rolling connection with the first connector 41 and the second connector 42. Thereby, rolling connection between the first and second connection members 41 and 42 can be achieved by the balls 43, and relative rotation between the first and second connection members 41 and 42 is easier.

It will be appreciated that the number of balls 43 engaged between the first connector 41 and the second connector 42 may be set according to practical requirements. The number of balls 43 may be 6, 8, 10, for example. The above numbers are merely illustrative, and the specific number of the balls 43 is not further limited.

As shown in fig. 7, fig. 7 is a schematic view illustrating a structure of the burner 100 at another angle according to an embodiment of the present application, and the first connector 41 may be connected to the distributor 21. The second connecting member 42 is located at a side of the first connecting member 41 remote from the distributor 21, and can be connected to the burner 10.

Thus, during use of the burner 100, the reaction force applied to the fire cover assembly 20 by the air flow in the ventilation fire hole 202 drives the first connecting piece 41 to rotate relative to the second connecting piece 42, so as to realize the rotation of the distributor 21 relative to the burner 10. Meanwhile, since the second link 42 and the plurality of balls 43 are rollingly coupled between the second link 42, friction between the first link 41 and the second link 42 is smaller, and the first link 41 is easier to rotate with respect to the second link 42, thereby making the rotation of the fire cover assembly 20 easier.

In order to facilitate fixing the balls 43, as shown in fig. 8, fig. 8 is a schematic structural view of a first connecting member 41 according to an embodiment of the present application, and one side of the first connecting member 41 has a first recess 411. Meanwhile, as shown in fig. 9, fig. 9 is a schematic structural diagram of a second connecting member 42 according to an embodiment of the present application, where one side of the second connecting member 42 has a second concave portion 421.

As shown in fig. 10, fig. 10 is a cross-sectional view of the ball 43 engaged between the first connector 41 and the second connector 42, wherein the first recess 411 is formed on a side of the first connector 41 adjacent to the second connector 42, and the second recess 421 is formed on a side of the second connector 42 adjacent to the first connector 41. The balls 43 may be clamped in the first recess 411 and the second recess 421.

In this way, through the first concave portion 411 and the second concave portion 421, the ball 43 can be clamped between the first connecting piece 41 and the second connecting piece 42 and be in rolling connection with the first connecting piece 41 and the second connecting piece 42, so that the structure is simple, and the manufacturing and the production are convenient.

It is understood that the shape of the first recess 411 and the second recess 421 may be adapted to the shape of the ball 43 as shown in fig. 10. As shown in fig. 10, the profiles of the cross-sectional shapes of the first recess 411 and the second recess 421 may be circular arc-shaped so that the balls 43 can be smoothly engaged in the first recess 411 and the second recess 421.

Of course, the balls 43 may be engaged between the first connector 41 and the second connector 42 in other manners. For example, one of the first and second connection members 41 and 42 may be provided with two slide rails disposed opposite to each other, and the other may be provided with a slide groove. The balls 43 may be engaged between the first connector 41 and the second connector 42 by the cooperation of the slide rail and the slide groove, and may be connected with the first connector 41 and the second connector 42 in a rolling manner.

In order to achieve the connection of the first connector 41 with the fire cover assembly 20, as shown in fig. 6, a plurality of connection posts 412 are formed at a side of the first connector 41 remote from the second connector 42. Correspondingly, as shown in fig. 11, fig. 11 is a schematic structural diagram of a fire cover assembly 20 according to an embodiment of the present application, and a connecting hole 203 is formed on a side of the distributor 21 close to the first connecting member 41 (fig. 10).

As shown in fig. 12, fig. 12 is a cross-sectional view of the burner 100 provided in an embodiment of the present application, and a connection post 412 may be positioned in the connection hole 203 to be connected with the connection hole 203. Thus, by providing the connection post 412 and the connection hole 203, the connection hole 203 on the fire cover assembly 20 can be directly inserted into the connection post 412 in the process of assembling the burner 100, so that the connection between the fire cover assembly 20 and the first connector 41 can be realized, and the connection is more convenient.

Of course, the fire cover assembly 20 and the first connector 41 may be connected in other ways. For example, the fire cover assembly 20 may have a connection post formed thereon. Correspondingly, the first connection member 41 may be formed with a connection hole. In this way, the connection between the fire cover assembly 20 and the first connector 41 can also be achieved by the cooperation of the connection post and the connection hole.

As an example, as shown in fig. 11, a connection block 211 is formed at one side of the distributor 21, and the connection block 211 may be provided with the connection hole 203. Thus, by arranging the connecting block 211, the overall thickness of the connecting block 211 in the distributor 21 is thicker, the connecting hole 203 is provided with the connecting block 211, so that the overall strength of the distributor 21 is not easy to influence, and the overall strength of the distributor 21 is ensured.

As can be seen from fig. 2, the burner 10 is provided with a gas mixing outlet 12 communicating with a gas mixing chamber 101. Meanwhile, as shown in fig. 11, a gas distribution inlet 204 communicating with a gas distribution chamber 201 (fig. 4) is provided at a side of the distributor 21 near the burner 10 (fig. 7).

In order that the gas mixture outlet 12 of the burner 10 may communicate with the gas distribution inlet 204 of the distributor 21, in some embodiments, as shown in fig. 8 and 9, the first and second connection members 41 and 42 may each be annular. Thus, as shown in fig. 12, the end of the burner 10 provided with the gas mixture outlet 12 may pass through the first connecting member 41 and the second connecting member 42 to communicate with the gas distribution inlet 204.

Because the first connecting piece 41 and the second connecting piece 42 are annular, the burner 10 can pass through the first connecting piece 41 and the second connecting piece 42 to be communicated with the gas distribution inlet 204 of the fire cover assembly 20, and the burner is simple in structure and more convenient to connect.

In addition, the second connector 42 is annular and is sleeved outside the burner 10. To achieve the connection between the second connector 42 and the burner 10, the second connector 42 may be in an interference fit with the burner 10, so that the second connector 42 and the burner 10 can be fixed and cannot rotate back and forth.

Of course, the second connecting piece 42 and the burner 10 may be connected and fixed by other manners, and may be specifically set according to practical situations, so long as the connection and fixation between the second connecting piece 42 and the burner 10 can be achieved. For example, one of the second connector 42 and the burner 10 may be provided with a connecting shaft, and the other one with a connecting hole. Thus, the second connector 42 and the burner 10 can be relatively fixed by the engagement between the connecting shaft and the connecting hole.

In some embodiments, as shown in fig. 12, the gas-dividing inlet 204 may be sleeved outside the end of the burner 10 where the gas-mixing outlet 12 is provided. In this way, the mixed gas flowing out from the mixed gas outlet 12 is not easy to flow out from the gas separation inlet 204, so that the risk of leakage of the mixed gas is reduced, and the use safety performance of the burner 100 is improved.

In some embodiments, as shown in fig. 2, the plenum 101 may include an inner plenum 102 and an outer plenum 103 that are independent of each other.
