[0032] In a first aspect, the present application provides a nozzle 10 for a gas stove. Figure 1 This is a structural diagram of an embodiment of the nozzle 10 of the gas stove provided by the present application. Figure 2 yes Figure 1 A top view of the nozzle 10 of the gas stove, Figure 3 yes Figure 1 A bottom view of the nozzle 10 of the gas stove, Figure 4 yes Figure 2 A cross-sectional view of the nozzle 10 of the gas stove along the section line AA, Figure 5 yes Figure 2 A cross-sectional view of the nozzle of the gas stove along the section line BB.

[0033] Combine Figure 1-Figure 5 The nozzle 10 of the gas stove includes a main body 11. The main body 11 is hollow to form a gas channel 111. The gas channel 111 is used to pass gas.

[0034] Specifically, the main body 11 of the nozzle 10 of the gas stove is used to introduce and discharge gas, and the gas channel 111 forms openings at the top and bottom ends of the main body 11 respectively. The gas enters the gas channel 111 from the opening at the bottom end of the main body 11 and is discharged from the opening at the top end of the main body 11. At this time, the top end of the main body 11 is also the gas outlet end of the main body 11.

[0035] The nozzle 10 of the gas stove includes a vent groove 112, which is provided at the gas outlet end of the main body 11. At this time, the vent groove 112 can be regarded as a downward depression of the end surface of the gas outlet end of the main body 11, thereby forming a groove structure with an opening located at the end surface of the gas outlet end and a closed bottom.

[0036] Specifically, the vent groove 112 is isolated from the gas passage 111 and forms a vent 1121 at the gas outlet end of the main body 11. The vent groove 112 is isolated from the gas passage 111, preventing the gas in the gas passage 111 from entering the vent groove 112. In this case, the vent groove 112 communicates with the outside world only through the vent 1121 and not with the gas passage 111. In conjunction with the provision of the vent 1121, the provision of the vent groove 112 at the gas outlet end of the main body 11 refers to the provision of the vent 1121 at the end surface of the vent groove 112 at the gas outlet end.

[0037] The nozzle 10 of the gas stove also includes a ventilation channel 113 , a first end of which is connected to the ventilation groove 112 , a second end of which passes through the side wall of the main body 11 and is connected to the outside, and the ventilation channel 113 is isolated from the gas channel 111 .

[0038] Specifically, the ventilation channel 113 is a sealed channel with openings only at both ends. External air can enter the ventilation channel 113 through the opening at the second end of the ventilation channel 113. The air entering the ventilation channel 113 can enter the ventilation groove 112 through the first end of the ventilation channel 113, thereby providing air to the ventilation groove 112 through the ventilation channel 113. The ventilation channel 113 is isolated from the gas channel 111, so that the air in the ventilation channel 113 does not enter the gas channel 111. In other words, the air in the ventilation channel 113 only enters the ventilation groove 112 and does not enter the gas channel 111.

[0039] The nozzle 10 of the gas stove also includes an air outlet 114, which is provided at the outlet end of the main body 11. The air outlet 114 is located around the vent 1121 and communicates with the gas passage 111. The gas in the gas passage 111 is discharged through the air outlet 114 and mixed with the air at the vent 1121. In combination with the arrangement of the ventilation groove 112 and the ventilation passage 113, the air outlet 114 is isolated from the ventilation groove 112, and the air outlet 114 is isolated from the ventilation passage 113.

[0040] Specifically, the gas outlet end of the main body 11 is a closed end to seal one end of the gas channel 111. However, this closed gas outlet end is provided with a gas outlet hole 114, which connects the gas channel 111 with the outside world, thereby allowing the gas in the gas channel 111 to be introduced to the outside world through the gas outlet hole 113. Air introduced from the outside into the ventilation groove 112 can be introduced to the outside world through the vent 1121. Because the gas outlet hole 114 is located around the vent 1121, the gas discharged from the gas outlet hole 114 can mix with the air discharged from the vent 1121.

[0041] In the field of gas stoves, the gas discharged from the nozzle must be fully mixed with air to achieve good combustion. The ratio of the amount of air mixed with the gas at the nozzle to the amount of air required to fully discharge the gas from the nozzle is the nozzle's primary air injection coefficient. To ensure sufficient combustion of the gas, a high primary air injection coefficient should be maintained.

[0042] The gas in the nozzle 10 of the gas stove provided in the present application can be introduced into the outside through the gas channel 111 and the air outlet 114. The gas introduced into the outside through the air outlet 114 can be mixed with the air discharged from the air port 1121 of the ventilation groove 112, thereby improving the primary air injection coefficient of the nozzle 10 of the gas stove and improving the combustion effect of the gas stove.

[0043] Combine Figure 1 as well as Figure 2 In some specific embodiments, there are multiple air outlet holes 114 , and the multiple air outlet holes 114 are arranged around the circumference of the vent 1121 , and two adjacent air outlet holes 114 are arranged at intervals around the circumference of the vent 1121 .

[0044] It should be understood that the peripheral side of the vent 1121 can be the peripheral portion of the outlet hole 114 located outside the vent 1121 and within the end surface of the outlet end. Two adjacent outlet holes 114 are arranged by spacing to ensure that the gas discharged from each outlet hole 114 can be fully mixed with the surrounding air.

[0045] This embodiment provides multiple gas outlet holes 114. The gas delivery rate from these multiple outlet holes 114 can be the same as that from a conventional nozzle having a single outlet hole. This allows the gas to be delivered through multiple outlet holes 114, ensuring thorough mixing of the gas while maintaining the same delivery rate. Furthermore, because the outlet holes 114 are positioned around the vent 1121, the gas delivered from these multiple outlet holes 114 can be mixed with the air at the vent 1121, further improving the primary air entrainment coefficient.

[0046] Figure 6 yes Figure 1A schematic structural diagram of the nozzle 10 of the gas stove in another perspective, Figure 7 yes Figure 6 sectional view of the nozzle 10 of the gas stove along the section line CC.

[0047] Combine Figure 6 as well as Figure 7 In some specific embodiments, there are multiple ventilation channels 113, and the first ends of the multiple ventilation channels 113 are arranged circumferentially on the inner wall of the ventilation groove 112, and the second ends of the multiple ventilation channels 113 are arranged circumferentially on the outer wall of the main body 11.

[0048] Specifically, the number of ventilation channels 113 is greater than or equal to two, and the first end of the ventilation channel 113 passes through the side wall of the ventilation groove 112, so that the first end of the ventilation channel 112 is arranged circumferentially on the inner wall of the ventilation groove 112, and the second end of the ventilation channel 113 passes through the side wall of the gas channel 111, so that the second end of the ventilation channel 113 is arranged circumferentially on the outer wall of the main body 11.

[0049] The first ends of the plurality of ventilation channels 113 can be arranged at the same height relative to the bottom end of the main body. Of course, the first ends of the plurality of ventilation channels 113 can also be arranged at intervals along the height direction of the main body 11, without specific limitation. Similarly, the arrangement of the second ends of the corresponding ventilation channels 113 can refer to the arrangement of the first ends of the ventilation channels 113.

[0050] By providing multiple ventilation channels 113, air can be introduced into the ventilation groove 112 from different positions of the main body 11, thereby ensuring that there is sufficient air in the ventilation groove 112. In addition, the multiple ventilation channels 113 are arranged at intervals around the circumference of the ventilation groove 112, so that each position around the vent 1121 of the ventilation groove 112 has relatively sufficient air, thereby providing sufficient air to the air outlet holes 114 provided around the vent 1121.

[0051] Continue to combine Figure 6 as well as Figure 7 In some specific embodiments, the second end of the ventilation channel 113 forms an air intake side hole 1131 on the main body 11. The air intake side holes 1131 are arranged at intervals in the circumferential direction of the main body 11, and the air intake side holes 1131 extend in the axial direction of the main body 11.

[0052] Specifically, the air inlet side hole 1131 is a strip-shaped hole, and the length direction of the air inlet side hole 1131 is the axial direction of the main body 11. By setting the air inlet side hole 1131 as a strip-shaped hole extending along the axial direction of the main body 11, air can be evenly and fully inlet in the height direction of the ventilation groove 112, thereby ensuring sufficient air intake.

[0053] In some specific embodiments, the top of the air inlet side hole 1131 can be set on the end face of the air outlet end of the main body 11 to ensure that the distance between the air inlet side hole 1131 and the air vent 1121 of the ventilation groove 112 is close, so that the air entering the air inlet side hole 1131 can be easily mixed with the gas discharged from the air outlet hole 114.

[0054] Combine Figure 2 as well as Figure 3 In some specific embodiments, the vent 1121 is arranged in a circular shape, and the multiple air outlet holes 114 are located on the same arc with the center of the vent 1121 as the center of the circle, and the distance between the air outlet holes 114 and the vent 1121 is less than the preset distance.

[0055] It should be understood that the air outlet 114 extends in the axial direction of the main body 11, so that the air outlet 114 is cylindrical in shape as a whole. In this embodiment, the air outlet 114 is located on the same arc, which means that the ends of the air outlet 114 at the outlet end are located on the same arc, and the distance between the air outlet 114 and the vent 1121 is the distance between the end of the air outlet 114 at the outlet end and the edge of the vent 1121.

[0056] By setting the distance between the air outlet 114 and the vent 1121 to be less than a preset distance, it is possible to ensure that the air at the vent 1121 can be easily mixed with the gas discharged from the air outlet 114. The preset distance can be determined based on multiple experiments. At this preset distance, the air discharged from the vent 1121 can be easily mixed with the gas discharged from the air outlet 114.

[0057] Figure 8 yes Figure 1 A schematic structural diagram of an embodiment of a nozzle 10 of a gas stove, Figure 9 yes Figure 8 A cross-sectional view of the nozzle 10 of the gas stove along the section line DD, Figure 10 yes Figure 8 sectional view of the nozzle 10 of the gas stove along the section line EE.

[0058] Combine Figure 4 、 Figure 5 、 Figure 9 as well as Figure 10 In some specific embodiments, a portion of the air outlet end of the main body 11 is recessed toward the gas channel 111 to form a vent pipe 12 , the outer wall of the vent pipe 12 is spaced from the inner wall of the gas channel 111 , the vent pipe 12 is hollow and the bottom end is closed to form a vent groove 112 .

[0059] Specifically, the lower end of the vent tube 12 is closed and hollow, forming a vent groove 112. The upper end of the vent tube 12 is formed with an opening to form a vent opening 1121 of the vent groove 112. The outer wall of the vent tube 12 is spaced apart from the inner wall of the gas channel 111. In some specific embodiments, the vent tube 12 can be positioned at the center of the gas channel 111. In this case, the distance between the outer wall of the vent tube 12 and the inner wall of the gas channel 111 can be equal at all locations.

[0060] Combine Figure 7 、 Figure 9 as well as Figure 10 In some specific embodiments, the nozzle 10 of the gas stove includes a connecting portion 13 , the two ends of which are respectively arranged on the inner wall of the gas channel 111 and the outer wall of the ventilation pipe 12 , and the connecting portion 13 is hollow to form a partial ventilation channel 113 .

[0061] Specifically, the connecting portion 13 is a tubular structure, and the length of the connecting portion 13 extends radially along the gas channel 111, thereby arranging the connecting portion 13 in the radial direction of the gas channel 111. A through hole is provided on the wall of the ventilation pipe 12, and a section of the connecting portion 13 is connected to the ventilation groove 112 through the through hole. In this case, the opening on the wall of the ventilation pipe 12 is also part of the ventilation channel 113. A through hole is also provided on the side wall of the main body 11, and one end of the connecting portion 13 is connected to the outside world through the through hole. In combination with the content of the above embodiment, the through hole on the side wall of the main body 11 can be the air inlet side hole 1131.

[0062] It should be understood that when both ends of the connecting portion 13 are connected to the outer wall of the vent pipe 12 or the inner wall of the gas channel 111 , there is no connection gap between the two connections to ensure that the gas in the gas channel 111 will not leak through the vent channel 113 .

[0063] Combine Figure 3 as well as Figure 7 A ventilation gap 131 is formed between two adjacent connecting parts 13 , and the gas outlet 114 is connected to the gas channel 111 through the ventilation gap 131 .

[0064] Specifically, the top of the connecting portion 13 can be arranged in contact with the bottom of the gas outlet end of the main body 11, and the side of the connecting portion 13 can be arranged in contact with the inner wall of the gas channel 111, thereby forming a ventilation gap 131 between two adjacent connecting portions 13, and the gas outlet hole 114 is arranged at one end of the ventilation gap 131.

[0065] In this embodiment, the ventilation gap 131 is not part of the gas channel 111. In other embodiments, the ventilation gap 131 may be part of the gas channel 111, which is not specifically limited here.

[0066] In this embodiment, the air outlet 114 is disposed within the ventilation gap 131, which does not affect the arrangement of the connection portion 13, facilitates the arrangement of the connection portion 13, and effectively utilizes the space within the main body 11. Furthermore, the gas within the gas passage 111 can be effectively introduced into the air outlet 114 through the ventilation gap 131. Furthermore, because the inner diameter of the ventilation gap 131 is smaller than that of the gas passage 111, the gas flow rate can be increased after it is introduced from the gas passage 111 into the ventilation gap 131, thereby increasing the flow rate of the gas discharged from the air outlet 114. Therefore, the present invention can be applied to certain application scenarios where a faster flow rate of the gas discharged from the air outlet 114 is required, thereby expanding the application range of the gas stove nozzle 10.

[0067] In combination with the above, the connection parts 13 can be arranged at equal intervals along the radial direction of the gas channel 111, thereby forming a plurality of ventilation gaps 131 arranged at equal intervals, so that the air outlet holes 114 arranged in the plurality of ventilation gaps 131 can be arranged at equal intervals.

[0068] Combine Figure 4 、 Figure 5 、 Figure 9 as well as Figure 10 In some specific embodiments, the end surface of the connecting portion 13 away from the gas outlet end is an arcuate surface 132, and the arcuate surface 132 is convex in the direction away from the gas outlet end. The arcuate surface 132 is used to guide the gas in the gas channel 111 to the ventilation gap 131.

[0069] Specifically, the bottom of the connecting portion 13 is convexly arranged to form an arcuate surface 132. The bottom of the arcuate surface 132 is relatively lowest on the main body 11, while the arcuate surface 132, the inner wall of the gas passage 111, and the two sides forming the ventilation gap 131 are relatively highest on the main body 11. When the airflow in the gas passage 111 flows toward the arcuate surface, the arcuate surface 132, due to its arcuate structure, can divert the airflow, significantly reducing the impact of the connecting portion 13 on the airflow velocity, ensuring that the gas entering the ventilation gap 131 has a higher flow rate, thus meeting the requirements of a higher gas flow rate in certain scenarios.

[0070] Another function of the setting of the arc surface 132 is that, due to the specific setting position of the arc surface 132, the gas flowing to the position of the arc surface 132 can be guided through the arc surface 132, so as to guide the gas at the arc surface 132 to the ventilation gap 131, so that the gas can be discharged from the outlet hole 114.

[0071] In combination with the arrangement of the plurality of ventilation channels 113 , a plurality of connection portions 13 are provided. Each of the plurality of connection portions 13 may be provided with an arcuate surface 132 , and the shape and curvature of the arcuate surfaces 132 of the plurality of connection portions 13 are the same.

[0072] Combine Figure 10 In some specific embodiments, the vent pipe 12 includes a straight cylindrical portion 121 and a conical portion 122. The conical portion is arranged at an end of the straight cylindrical portion away from the vent. The vent channel is connected to the inner cavity of the straight cylindrical portion. The conical portion is used to guide the gas in the gas channel from the circumferential side of the conical portion to the outlet.

[0073] Specifically, the straight cylindrical portion 121 and the conical portion 122 of the vent tube 12 can be integrally formed to ensure structural stability. Both the straight cylindrical portion 121 and the conical portion 122 can be hollow structures, in which case the vent groove 112 is formed by the inner cavities of the straight cylindrical portion 121 and the conical portion 122. Of course, in other embodiments, only the straight cylindrical portion 121 can be hollow to form the vent groove 112, while the conical portion 122 is solid.

[0074] Combined with the arrangement of the vent groove 112 , the vent opening 1121 of the vent groove 112 is formed by the upper end of the straight tube portion 121 , and the air in the vent groove 112 passes through the straight tube portion 121 and is discharged from the vent opening 1121 .

[0075] In combination with the above-mentioned setting of the connecting portion 13, one end of the connecting portion 13 is connected to the straight tube portion 121. At this time, a through hole is opened on the side wall of the straight tube portion 121, and the connecting portion 13 is connected to the inner cavity of the straight tube portion 121 through the through hole opened on the straight tube portion 121, that is, connected to the ventilation groove 112. Figure 9 , the bottom of the connecting portion 13 is located on the straight tube portion 121 , and at this time, the length of the connecting portion 13 is smaller than the length of the straight tube portion 121 .

[0076] The conical portion 122 allows the gas flow in the gas passage 111 to flow onto the conical portion 122. The conical surface of the conical portion 122 guides the flow, preventing the vent pipe 12 from significantly affecting the gas flow rate. This configuration prevents the vent pipe 12 from significantly affecting the gas flow rate, meeting the requirements for higher gas flow rates in some applications, thereby expanding the application range of the gas stove nozzle 10.

[0077] Another function of the conical portion 122 is to guide the gas flowing onto the conical portion 122 toward the periphery of the conical portion 122, thereby causing the gas to flow toward the periphery of the conical portion 122. Combined with the configuration of the ventilation gap 131 and the gas outlet 114, the conical portion 122 can guide the gas flow into the surrounding ventilation gap 131, and then discharge it to the outside through the ventilation gap 131 and the gas outlet 114.

[0078] In some embodiments, to ensure good flow guidance of the conical portion 122, the angle between the generatrix of the conical portion 122 and the horizontal axis can be set to a range of 15 degrees to 30 degrees. For example, the angle between the generatrix of the conical portion 122 and the horizontal axis can be set to 20 degrees to ensure good flow guidance.

[0079] Of course, in other embodiments, the angle between the generatrix of the conical portion 122 and the horizontal axis may not be within the range of 15 to 30 degrees, as long as it can provide a certain flow guidance effect. In such embodiments, the conical portion 122 can be configured according to specific application scenarios and application requirements, thereby expanding the application range of the gas stove nozzle 10.

[0080] To sum up the above:

[0081] The nozzle 10 of the gas stove provided in the present application is provided with a ventilation groove 112. The gas in the nozzle can be introduced into the outside through the gas channel 111 and the air outlet 114. The gas introduced into the outside through the air outlet 114 can be mixed with the air discharged from the air port 1121 of the ventilation groove 112, thereby improving the primary air injection coefficient of the nozzle 10 of the gas stove and improving the combustion effect of the gas stove.

[0082] In some embodiments, the provision of multiple air outlets 114 can, on the one hand, achieve better air mixing, thereby further increasing the primary air injection coefficient. On the other hand, while maintaining the same amount of stove gas output, gas can be discharged through multiple air outlets 114, thereby reducing noise generated by the gas being discharged from the air outlets.

[0083] In some embodiments, the provision of multiple ventilation channels 113 ensures that sufficient air can flow into the ventilation groove 112 to ensure good air mixing. Furthermore, the air inlet side holes 1131 of the ventilation channels 113 are arranged along the axial direction of the main body 11 and near the air outlet end, facilitating mixing of the gas with the air discharged from the vent 1121. Furthermore, the bottom of the connecting portion 13 is formed with an arcuate surface 132, which, on the one hand, reduces the impact of the connecting portion 13 on the flow rate of the gas, and, on the other hand, guides the gas into the ventilation gap 131, allowing the gas to be discharged from the air outlet 114 within the ventilation gap 131.

[0084] In some embodiments, the provision of the conical portion 122 can, on the one hand, reduce the effect of the connecting pipe 12 on the flow velocity of the gas flow, and on the other hand, guide the gas flow in the gas channel 111 to the ventilation gap 131 to facilitate the discharge of the gas.

[0085] In summary, the nozzle 10 of the gas stove provided in the present application has multiple beneficial effects such as achieving good mixing between gas and air, reducing noise, ensuring a high flow rate, and good gas extraction.

[0086] A second aspect of the present application provides a gas stove 20, Figure 11 This is a structural diagram of an embodiment of a gas stove 20 provided in this application. Figure 12 yes Figure 11 A schematic diagram of the enlarged structure of the gas stove 20 area A.

[0087] Combine Figure 11 as well as Figure 12 The gas stove 20 includes a burner 21 and an ejector tube 22. The ejector tube 22 is connected to the burner 21. The ejector tube 22 is used to pass gas into the burner 21 for combustion. The flame burning in the burner 21 can heat the pot on the burner.

[0088] More specifically, the gas stove 20 also includes a nozzle 10 of a gas stove as in any of the above embodiments. The nozzle 10 of the gas stove is arranged on the side of the ejector tube 22 away from the burner head 21. The nozzle 10 is used to introduce gas into the ejector tube 22 so that the ejector tube 22 introduces a mixture of gas and air into the burner head 21 for combustion.

[0089] The gas stove 20 further includes a gas source assembly 23. The gas stove nozzle 10 is disposed between the gas source assembly 23 and the ejector tube 22. The gas source assembly 23 directs the gas into the gas stove nozzle 10 and performs preliminary air mixing at the gas stove nozzle 10. There may be multiple ejector tubes 22, and multiple gas stove nozzles 10 may be correspondingly disposed between the ejector tubes 22 and the gas source assembly 23, thereby fully mixing the gas introduced into the ejector tubes 22.
