In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0059] Combine the following Figure 1-Figure 10 The burner of the present application is described. It is understood that a gas stove refers to a kitchen appliance that uses gas fuels such as liquefied petroleum gas, artificial coal gas, and natural gas for direct fire heating. The gas stove mainly includes a burner, a valve body, a stove rack, a knob, a liquid tray, a stove foot, an air inlet pipe, and a pulse igniter, wherein the burner includes a burner head and a fire cover, the gas is ignited at the burner, and the flame is ejected from the fire cover for heating.

[0060] See also Figure 1 and Figure 2 As shown, the burner 100 according to the embodiment of the present application includes a base 110 , a mounting base 120 , a fire cover 130 and an ejector 140 .

[0061] Specifically, the ejector 140 is connected to the base 110, and the ejector 140 is used to pressurize the mixed gas to overcome the resistance loss of the delivery channel, so that the gas can obtain a certain speed at the combustion point to ensure the stability of the combustion flame. The mounting base 120 is connected to the base 110, and one side of the mounting base 120 and the base 110 together define a buffer chamber, and one side of the mounting base 120 and at least one of the base 110 form a groove structure, and the mounting base 120 and the base 110 are connected so that the groove structure is closed to form a buffer chamber. The buffer chamber is connected and communicated with the ejector 140, and the inner wall of the buffer chamber can be connected to the output port of the ejector 140, or the inner wall of the buffer chamber and the ejector 140 can be indirectly connected through a connecting structure. The gas is transported to the buffer chamber through the ejector 140, and the buffer chamber can reduce the pressure on the gas and mix the gas evenly. Figure 2 As shown, a groove-shaped structure is provided on the top of the base 110 , and the mounting seat 120 is covered on the top of the base 110 . The groove-shaped structure and the bottom surface of the mounting seat 120 define a buffer cavity.

[0062] The fire cover 130 is disposed on the other side of the mounting base 120. The fire cover 130 and the mounting base 120 define a gas channel together. The gas channel is connected to the buffer cavity. The bottom of the gas channel is connected to the top of the buffer cavity. Alternatively, the gas channel and the buffer cavity may be connected through a connecting channel. Figure 2 As shown, the fire cover 130 is suitable for covering the top of the mounting base 120. The top of the mounting base 120 may be provided with a groove structure, and the groove structure and the fire cover 130 together define a gas channel. The fire cover 130 is provided with a plurality of fire outlet holes, which are through holes to connect the gas channel with the outside. The gas in the gas channel is ejected from the fire outlet holes and ignited, and the flame is ejected from the fire outlet holes. Figure 5 and Figure 6 As shown, the ejector 140 inputs the gas into the buffer cavity, and the gas flows into the gas channel after being decompressed and diffused in the buffer cavity, and is ignited at the ignition hole of the fire cover 130. The buffer cavity is defined by the connection between the base 110 and the mounting seat 120, and the gas channel is defined by the connection between the mounting seat 120 and the fire cover 130. The base 110 and the mounting seat 120 are assembled in the form of multiple components, and the base 110 and the mounting seat 120 are processed separately during manufacturing to reduce the manufacturing difficulty.

[0063] It is understandable that the pressure of the gas outputted by the ejector 140 is relatively high. If the gas is directly outputted from the ejector 140 to the gas channel, the gas diffusion in the gas channel causes a flow velocity loss, so that the gas flow velocity near the ejector 140 is high, and the gas flow velocity far from the ejector 140 is low. As a result, the flame length near the ejector 140 on the fire cover 130 is too long, and the flame is uneven, and the heating object is heated unevenly. By setting a buffer cavity, the gas outputted by the ejector 140 is decompressed and diffused in the buffer cavity, which can make the gas speed more uniform and the flow velocity more consistent, thereby ensuring that the gas flow rate and flow velocity are uniform when it is ejected from the fire cover 130 through the gas channel, improving the gas combustion efficiency, and producing a uniform flame.

[0064] According to the burner 100 of the embodiment of the utility model, a buffer chamber is provided so that the gas output by the ejector 140 is decompressed and diffused in the buffer chamber, which can make the speed of the gas more uniform and the flow rate more consistent, thereby ensuring that the flow rate and flow rate of the gas when it is ejected from the fire cover 130 through the gas channel are uniform, thereby improving the gas combustion efficiency and producing a uniform flame.

[0065] See also Figure 2 and Figure 3As shown, according to some embodiments of the utility model, the buffer cavity and the gas channel are both annular, and the buffer cavity and the gas channel can be stacked to facilitate the diffusion of gas from the buffer cavity into the gas channel, so that the gas in the gas channel is evenly distributed. The buffer cavity extends along the gas channel, and the shape of the buffer cavity is similar to that of the gas channel. The buffer cavity and the gas channel are arranged opposite to each other, so that the cross-sectional area of ​​the gas channel and the buffer cavity can be increased, and the speed of the gas diffusion from the buffer cavity to the gas channel can be increased, so that the gas flow rate ejected from the fire cover 130 is uniform.

[0066] According to some embodiments of the present invention, the mounting base 120 includes a bottom plate 121 and an extension body. The bottom plate 121 is connected to the base 110, and one side of the bottom plate 121 and the base 110 define a buffer cavity.

The extension body can extend in a direction perpendicular to the plate body or can extend obliquely. The fire cover 130 is covered on the extension body. The fire cover 130 is connected to the extension body to define a gas channel. For example, a groove structure can be provided on the extension body. The fire cover 130 is covered on the groove structure and forms a gas channel. The fire cover 130 and the extension body can be buckled or connected by threads. There is a connecting channel in the extension body. The connecting channel is used to connect the buffer cavity and the gas channel. The ejector 140 injects the gas into the buffer cavity. After the gas is decompressed and mixed evenly in the buffer cavity, it flows into the gas channel from the connecting channel. The gas in the gas channel is ejected from the fire outlet on the fire cover 130 and ignited.

[0077] According to some embodiments of the present invention, the hollow structure inside the second extension body 123 defines a second connecting channel 127, one end of the second connecting channel 127 is connected to the second gas channel 125, and at least part of the other end of the second connecting channel 127 is connected to the second buffer chamber 117. Figure 6 and Fig.10 As shown, one end of the second extension body 123 is connected to the bottom plate 121, and the second extension body 123 has an inner cylinder and an outer cylinder, both of which are annular. The outer cylinder surrounds the inner cylinder and the two are spaced apart. The outer cylinder and the inner cylinder together define a second connecting channel 127. The upper end of the second connecting channel 127 (such as Figure 6 The lower end of the second connecting channel 127 is connected to the second gas channel 125 (as shown in the direction of FIG. Figure 6 In some embodiments, the bottom wall of the second connecting channel 127 is complete, and a hollow structure is provided on the bottom wall to connect with the second buffer cavity 117, that is, the portion of the bottom plate 121 between the inner cylinder and the outer cylinder is provided with a hollow structure to connect with the second buffer cavity 117.

[0078] like Figure 6 and Figure 7As shown, the second buffer cavity 117 is constructed on the base 110 as a first connecting rib 111, and the second extension 123 is constructed as a second connecting rib 1231. The second connecting channel 127 is connected to the second buffer cavity 117 at the second connecting rib 1231. Figure 6 The second connecting rib 1231 is constructed in the direction shown in the figure, the lower end of the inner cylinder of the second extension body 123 is constructed with the second connecting rib 1231, the first connecting rib 111 and the second connecting rib 1231 are adapted to each other, and the first connecting rib 111 and the second connecting rib 1231 are connected. The second connecting rib 1231 is sealed with the first connecting rib 111 to improve the sealing of the second buffer cavity 117 and the second connecting channel 127. For example, the first connecting rib 111 and the second connecting rib 1231 can be connected by a sealant.

[0079] In order to facilitate understanding of the structure of the burner 100 of the present application, a working process of an embodiment is provided below:

[0080] like Figure 5 As shown, the mixed gas is injected into the first air inlet cavity 114 from the first ejector pipe 141. The inclined surface in the first air inlet cavity 114 initially decelerates the gas and guides the gas to flow into the first buffer cavity 116. After the gas enters the annular first buffer cavity 116, it flows and diffuses in the first buffer cavity 116, so that the gas is mixed evenly and the gas flow speed in the first buffer cavity 116 tends to be consistent. The gas in the first buffer cavity 116 flows upward (as shown in FIG. Figure 5 The gas flows in the direction shown in the figure, and along the multiple first connecting channels 126 arranged in the circumferential direction of the first gas channel 124, the gas flows into the first gas channel 124 through the multiple first connecting channels 126. In this way, the first gas channel 124 can be evenly filled with gas, so that the flow rate and flow velocity of the gas sprayed from the multiple fire holes of the outer ring fire cover 131 are uniform, which reduces the difference in the flow rate and flow velocity of the gas, improves the gas combustion efficiency, and makes the generated flame more uniform, so that the pot body is evenly heated and the probability of sticking to the pot is reduced.

[0081] See also Figure 6 As shown, the mixed gas is injected into the second air inlet chamber 115 from the second ejector pipe 142. The inclined surface in the second air inlet chamber 115 initially decelerates the gas and guides the gas to flow into the second buffer chamber 117. After the gas enters the second buffer chamber 117, it flows and diffuses in the second buffer chamber 117, so that the gas is evenly mixed and the gas flow speed in the second buffer chamber 117 tends to be consistent. The gas in the second buffer chamber 116 flows upward (as shown in FIG. Figure 6In this way, the second gas channel 125 can be evenly filled with gas, so that the flow rate and flow velocity of the gas sprayed from the multiple fire holes of the central fire cover 132 are uniform, the difference in the flow rate and flow velocity of the gas is reduced, the gas combustion efficiency is improved, and the generated flame is more uniform, so that the pot body is evenly heated and the probability of sticking is reduced.

[0082] It is understandable that in the burner 100, the gas flowing to the outer ring fire cover 131 and the gas flowing to the center fire cover 132 are not mixed. When the gas is burning, air can flow from the gas supply channel 128 and the gas supply hole 1281 to between the first extension body 122 and the second extension body 123 to provide sufficient oxygen to ensure full combustion of the gas.

[0083] According to the gas stove of the embodiment of the utility model, the burner 100 as described above is included. By setting a buffer cavity, the gas outputted by the ejector 140 is decompressed and diffused in the buffer cavity, so that the speed of the gas can be more uniform and the flow rate can be more consistent, thereby ensuring that the flow rate and flow rate of the gas when it is ejected from the fire cover 130 through the gas channel are uniform, improving the gas combustion efficiency, generating a uniform flame, ensuring uniform heating, and reducing the probability of sticking to the pan.

[0084] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not deviate from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the present invention.
