Description

Technical Field

[0001] The utility model relates to the technical field of cooking stoves, in particular to a gas stove. Background Art

[0002] A gas stove refers to a kitchen appliance that uses gases such as liquefied petroleum gas, artificial gas, and natural gas as fuels for heating.

[0003] The main components of the most important combustion system in a gas stove include an ejector pipe, an injection device, a burner head, and a burner cap. The fuel is injected into the ejector pipe through the injection device. During the process of the fuel being injected into the ejector pipe, the high-speed flowing fuel will entrain primary air. The primary air and the fuel enter the ejector pipe and mix. The primary air can provide oxygen for the fuel combustion. However, the ability of the gas to naturally entrain primary air is limited. When the primary air is insufficient, it will affect the full combustion of the gas and the thermal efficiency of the gas stove.

[0004] In order to solve the problem of insufficient primary air, primary air can be blown into the ejector pipe through a blower device. However, compared with natural entrainment, the primary air directly blown into the ejector pipe through the blower device lacks the process of mixing of the primary air and the fuel during the natural entrainment process. Therefore, the mixing effect of the primary air and the fuel is poor. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a gas stove, aiming to solve the problems of adding a blower device and poor mixing effect of the primary air provided by the blower device.

[0055] The present application provides a gas stove, as Figure 1 shown, Figure 1 is a schematic diagram of a gas stove 100 provided by the present application. The gas stove 100 provided by the present application may include a bottom case 11, a panel 12, and a burner 2. Among them, the bottom case 11 forms an installation cavity 10 with an opening. The bottom case 11 is mainly used to install relevant components of the gas stove 100, such as, for example, the burner 2, a gas control system, and an electronic ignition assembly, etc. These components are arranged in the installation cavity 10 of the bottom case 11 of the gas stove. Among them, the burner 2 is arranged in the installation cavity 10 of the bottom case 11. The burner 2 is the core component of the gas stove 100, and through the burner 2, fuel and primary air can be mixed and burned in a certain manner.

[0056] On this basis, the above-mentioned panel 12 covers the bottom case 11, and the panel 12 is used to cover the installation cavity 10 of the bottom case 11. In this way, the panel 12 can play a protective role for the components arranged in the installation cavity 10.

[0057] In addition, an avoidance hole 120 is formed in the panel 12, and the burner 2 is disposed opposite to the avoidance hole 120. In this way, when the burner 2 burns fuel to generate a flame, the panel 12 will not block the flame generated by the burner 2 burning fuel, ensuring that the burner 2 can operate normally.

[0058] Continue to refer to Figure 1 and Figure 2 , in addition to the above main components, the gas stove 100 further includes some components that are essential for the realization of the gas stove 100. These components include a valve body 14, a knob 15, an ignition needle 16, a thermocouple 17, etc.

[0059] Among them, the valve body 14 is used to control the on-off of the gas in the burner 2 or to control the increase or decrease of the gas flow rate. The knob 15 is connected to the valve body 14, so that the user can control ignition and the size of the flame through the knob 15. When the knob 15 is rotated, fuel flows into the burner 2, and the fuel is mixed with the primary air in the burner 2 and flows out therefrom. When the knob 15 is rotated, the ignition needle 16 ignites the flowing fuel, and the fuel burns to form a flame.

[0060] When the gas stove 100 goes out, the thermocouple 17 will sense the flameout, and thus can control the valve body 14 to close through relevant operations to stop delivering gas to the burner 2. For example, the thermocouple 17 is electrically connected to the controller. After the thermocouple 17 senses the flameout, it sends an electrical signal to the controller. After receiving the electrical signal sent by the thermocouple 17, the controller controls the valve body 14 electrically connected thereto to close.

[0061] Continue to refer to Figure 1 , the gas stove 100 may further include some components to improve the gas stove 100. A knob mounting hole 150 is formed in the panel 12, and the knob 15 is mounted in the knob mounting hole 150. In this case, in order to prevent the liquid accidentally spilled from the cookware from flowing into the installation cavity 10 of the bottom case 11 through the knob mounting hole 150, the gas stove 100 may further include a knob waterproof ring 151, which is disposed at the knob mounting hole 150 to prevent the spilled liquid from flowing into the installation cavity 10 of the bottom case 11 through the knob mounting hole 150.

[0062] Similarly, the spilled liquid may also flow into the interior of the bottom case 11 from the avoidance hole 120 on the panel 12. Therefore, a liquid receiving tray 121 is provided at the avoidance hole 120, and the spilled liquid can flow into the liquid receiving tray 121. In order to further ensure that the spilled liquid will not flow into the installation cavity 10 of the bottom case 11, a liquid receiving tray waterproof ring may be further provided around the liquid receiving tray 121 for further sealing.

[0063] Next, the above burner will be further described in conjunction with the accompanying drawings, as Figure 3As shown, the burner provided by the present application includes a burner head 21, and the burner head 21 is an important component of the burner 2. A cavity 210 is formed inside the burner head 21. Fuel and primary air can be mixed in the cavity 210 formed by the burner head 21 in a certain manner, and the mixed fuel and primary air can flow out of the cavity 210 and be ignited to form a flame.

[0064] On this basis, the gas stove 100 provided by the present application further includes an ejector pipe, as Figure 3 shown, one end of the ejector pipe 22 is connected to the burner head 21. Fuel and primary air can enter the burner head 21 through the ejector pipe 22 and be mixed in the burner head 21.

[0065] Continuing to refer to Figure 3 , the gas stove 100 provided by the present application further includes a burner cap assembly 1000. The burner cap assembly 1000 is covered on the above-mentioned burner head 21, and fire holes 1001 are formed on the burner cap assembly 1000. The fire holes 1001 are communicated with the cavity 210 of the burner head 21. In this way, the mixed gas of fuel and primary air in the cavity 210 can flow out of the fire holes 1001 to the outside of the burner cap assembly 1000 and be ignited to form a flame.

[0066] Based on this, referring to Figure 4 , the gas stove 100 provided by the present application further includes a burner cap assembly 1000. The burner cap assembly 1000 is covered on the above-mentioned burner head 21, and fire holes 1001 are formed on the burner cap assembly 1000. The fire holes 1001 are communicated with the cavity 210 of the burner head 21. In this way, the mixed gas of fuel and primary air in the cavity 210 can flow out of the fire holes 1001 to the outside of the burner cap assembly 1000 and be ignited to form a flame.

[0067] The process of the above fuel jet injecting into the ejector pipe 22 and ejecting primary air is called natural ejection. When the fuel is ejected from the nozzle 23 at a certain speed and pressure, a high-speed jet will be formed. During the flow of this jet, its speed is higher than that of the surrounding air, and a local negative pressure area will be formed near the fuel jet, thereby attracting the nearby air, so that the nearby air enters the ejector pipe 22 together with the fuel jet.

[0068] It should be noted that the amount of primary air will affect the height of the flame at the fire hole. Compared with the situation where the content of primary air is less, when the content of primary air is more, the height of the flame at the fire hole will be less than that when the content of primary air is less. In the case where the insufficient primary air causes the flame height to increase, in order to ensure complete combustion of the fuel and qualified flue gas indexes, it is necessary to increase the distance between the bottom of the cookware and the burner cap, which will increase the heat loss of the flame, thereby resulting in a decrease in the thermal efficiency of the gas stove.

[0069] Based on this, it can be understood that increasing the amount of primary air can reduce the flame height, thereby solving the above problem of heat dissipation of the flame. However, the natural entrainment ability of the gas jet is limited. When the natural entrainment of primary air by the gas reaches the limit and the primary air still cannot make the gas burn sufficiently, in order to make the gas burn sufficiently and ensure that the flue gas index is qualified, it is necessary to increase the distance between the cookware and the burner cap, which will result in the above problem of reduced thermal efficiency of the gas stove.

[0070] To solve the above problem of the limited ability of the gas to naturally entrain primary air, in the related art, a blower device is provided to directly blow air into the injection pipe as primary air by using a fan. Compared with the natural entrainment of air by the gas jet as primary air, the air directly blown into the injection pipe by the fan lacks the mixing process of the gas and air during the natural entrainment. Therefore, when the air is directly blown into the injection pipe by the fan, the mixing effect of the fuel and the primary air is poor.

[0071] In this case, to solve the defect of poor mixing effect between the primary air and the fuel. As Figure 5 shown, the gas stove provided by the present application further includes an air supply device 3, and the air supply device 3 includes an air supply component 31, and the air supply component 31 covers the other end of the injection pipe 22. As Figure 6 shown, the air supply component 31 is formed with an air inlet 301 and an air outlet 302, wherein the air outlet 302 is communicated with the inside of the injection pipe 22.

[0072] See Figure 7 , an air duct 30 is formed inside the air supply component 31. The air inlet 301 and the air outlet 302 (see Figure 6 ) are communicated with the air duct 30. Among them, the air outlet 302 is communicated with the inside of the injection pipe 22.

[0073] As Figure 6 shown, the air supply device 3 provided by the present application further includes a fan mounting bracket 320. The fan mounting bracket 320 is connected to the air supply component 31, and the fan mounting bracket 320 is located on the side of the air supply component 31 close to the injection pipe 22. In this way, the fan 32 can be installed and fixed through the fan mounting bracket 320. Figure 5 )

[0074] In this way, the fan 32 can blow air into the air duct 30 of the air supply component 31 through the air inlet 301, and then blow the air into the injection pipe 22 through the air duct 30 to achieve the purpose of supplementing the primary air.

[0075] On this basis, as Figure 8 shown, the air supply device 3 provided by the present application further includes a fan mounting bracket 320. The fan mounting bracket 320 is connected to the air supply component 31, and the fan mounting bracket 320 is located on the side of the air supply component 31 close to the injection pipe 22. In this way, the fan 32 can be installed and fixed through the fan mounting bracket 320.

[0076] Exemplarily, a through hole 3200 is formed in the mounting bracket 320, a connecting portion 321 is formed on the blower 32, and a through hole 3200 is also formed on the connecting portion 321. Based on this, a bolt can be passed through the through holes 3200 formed in the connecting portion 321 and the mounting bracket 320, and then a nut is threadedly connected to the bolt, so as to fixedly mount the mounting bracket 320 on the blower bracket 320.

[0077] Based on this, in order to solve the problem of poor mixing effect of air and fuel when the blower 32 directly blows air into the ejector pipe 22. As Figure 9 shown, an installation hole 310 is formed in the air supply assembly 31 provided in the present application, and the nozzle 23 is passed through the installation hole 310.

[0078] On this basis, as Figure 10 shown, the air supply assembly 31 is further provided with a nozzle avoidance hole 311, and the nozzle avoidance hole 311 is coaxially arranged with the installation hole 310; in this way, when the nozzle 23 is passed through the installation hole 310, the nozzle 23 and the nozzle avoidance hole 311 are also coaxially arranged, ensuring the spraying effect when the nozzle 23 sprays fuel.

[0079] The above nozzle avoidance hole 311 is communicated with the air duct 30, and the nozzle avoidance hole 311 is also communicated with the inside of the ejector pipe 22. In addition, the nozzle 23 and the nozzle avoidance hole 311 are arranged at intervals. It should be noted that the nozzle 23 and the nozzle avoidance hole 311 are arranged at intervals in the radial direction of the nozzle avoidance hole 311.

[0080] Based on this, when the nozzle 23 sprays fuel into the ejector pipe 22, a part of the air in the air duct 30 can flow into the ejector pipe 22 through the air outlet 302 to achieve the purpose of supplementing primary air.

[0081] Another part of the air in the air duct 30 can also flow into the ejector pipe 22 through the nozzle avoidance hole 311 communicated with the air duct 30. Since the nozzle 23 and the nozzle avoidance hole 311 are arranged at intervals. Therefore, when the nozzle 23 sprays fuel into the ejector pipe 22, the air flowing into the ejector pipe 22 from the nozzle avoidance hole 311 can be ejected. In this way, the fuel ejected from the nozzle 23 can be mixed with at least part of the air provided by the blower 32 before entering the ejector pipe 22, thus solving the problem of insufficient mixing of the air provided by the blower and the fuel.

[0082] Moreover, the gap formed by the spaced arrangement between the nozzle 23 and the nozzle avoidance hole 311 can play a role in combing the flow direction of the air flow, so that the air flowing out between the nozzle 23 and the nozzle avoidance hole 311 can flow along the axis direction of the nozzle 23. In this way, the air flowing out from the gap between the two has the same flow direction as the axis direction of the ejector tube 22, making the air flow smoother. And it makes the air flow along the periphery of the nozzle 23, and the flow direction is the same as the flow direction of the fuel ejected from the nozzle 23. In this way, the influence of the air supplemented by the blower on the fuel ejected from the nozzle 23 is minimized, and it is beneficial for the fuel jet and the air to enter the ejector tube 22 at a faster speed.

[0083] As Figure 9 shown, in some embodiments of the present application, an oxygen-increasing air inlet 2300 is provided on the nozzle 23 provided in the present application, and the oxygen-increasing air inlet 2300 communicates with a gas flow channel 230 opened inside the nozzle 23. In this way, during the process of the nozzle 23 ejecting fuel, a part of the primary air can also be ejected through the oxygen-increasing air inlet 2300.

[0084] As Figure 11 shown, the air supply assembly 31 provided in the present application includes a connecting member 41, and one end of the connecting member 41 is connected to the blower 32. The air supply assembly 31 further includes an air supply member 42, one end of the air supply member 42 is connected to the other end of the connecting member 41, and the other end of the air supply member 42 is connected to the ejector tube 22. The air supply member 42 forms the above-mentioned air duct 30, and one end of the air duct 30 communicates with the ejector tube 22 (communicates with the ejector tube 22 through the air outlet 302, see Figure 7 ), the other end of the air duct 30 communicates with the connecting member 41, and the axes of the connecting member 41 and the air supply member 42 are perpendicular.

[0085] In this way, the blower 32 connected to the connecting member 41 can be located on one side of the ejector tube 22 (the left or right side of the ejector tube 22). When the blower 32 is arranged on the left or right side of the ejector tube 22, the space occupied by the air supply device 3 in the axis direction of the ejector tube 22 can be shortened, playing a role in reducing the overall occupied space of the air supply device 3.

[0086] As Figure 12 shown, the above-mentioned air supply member 42 includes a front plate 421, and the aforementioned mounting hole 310 is opened on the front plate 421.

[0087] On this basis, as Figure 12 shown, the air supply member 42 further includes a rear plate 422, the rear plate 422 covers the other end of the ejector tube 22, and the rear plate 422 is connected to the front plate 421. The rear plate 422 and the front plate 421 enclose the air duct 30. In addition, it should be noted that the aforementioned nozzle avoidance hole 311 is opened on the rear plate 422.

[0088] It should be noted that, as Figure 12As shown, a surrounding plate 4220 is formed on the surface of the rear plate 422 close to the front plate 421 side, and the surrounding plate 4220 is perpendicular to the rear plate 422. Based on this, the front plate 421, the rear plate 422, and the surrounding plate 4220 formed on the rear plate 422 enclose an air duct 30.

[0089] As Figure 12 shown, the air supply member 42 further includes a connecting surrounding plate 423, which is located at one end of the front plate 421 and the rear plate 422, and the connecting surrounding plate 423 is connected to one of the front plate 421 and the rear plate 422. For example, it is connected to the rear plate 422.

[0090] As Figure 13 shown, the connecting surrounding plate 423 is formed with a connecting port 4230. One end of the connecting port 4230 is communicated with the air duct 30, and the other end of the connecting port 4230 can be communicated with the connecting member 41 ( Figure 11 ).

[0091] In order to enable the front plate 421 and the rear plate 422 to be connected to enclose the air duct 30. As Figure 12 shown, a first connecting portion 4211 is formed on the front plate 421, and a second connecting portion 4221 is formed on the rear plate 422. The first connecting portion 4211 and the second connecting portion 4221 are arranged opposite to each other. A first mounting hole 42110 is formed on the first connecting portion 4211, and a second mounting hole 42210 is formed on the second connecting portion 4221. The second mounting hole 42210 and the first mounting hole 42110 are coaxially arranged. In some embodiments, the first mounting hole 42110 may be a through hole, and the second mounting hole 42210 may be a threaded hole. Based on this, a screw can be passed through the first mounting hole 42110 and the second mounting hole 42210, so that the screw is threadedly connected to the second mounting hole 42210, thereby achieving the purpose of connecting the front plate 421 and the rear plate 422.

[0092] In addition, as Figure 14 shown, a third mounting hole 51 and a fourth mounting hole 52 are respectively formed on the front plate 421 and the rear plate 422. The third mounting hole 51 penetrates the front plate 421, and the fourth mounting hole penetrates the rear plate 422. And the third mounting hole 51 and the fourth mounting hole 52 are arranged opposite to each other. Among them, the third mounting hole 51 may be a through hole, and the fourth mounting hole 52 is also a through hole. It is installed on the ejector tube, and the mounting hole 52 separates the through hole from the air duct 30. It should be noted that in order to enable the screw passing through the third mounting hole 51 and the fourth mounting hole 52 to be threadedly connected to the ejector tube 22, a threaded hole can be formed at the corresponding position of the ejector tube.

[0093] In this way, a screw (or bolt) can be passed through the third mounting hole 51 and the fourth mounting hole 52. The screw is threadedly connected to the fourth mounting hole 52, and the screw is also threadedly connected to the ejector pipe 22. Thereby, the air supply member 42 is connected to the ejector pipe 22.

[0094] In some embodiments of the present application, as Figure 13 shown, a first positioning ring 61 is formed on the front plate 421. As Figure 15 shown, the first positioning ring 61 can abut against the rear plate 422. That is, the first positioning ring 61 abuts against the surrounding plate 4220 formed on the rear plate 422, and the first positioning ring 61 abuts against the inner wall of the surrounding plate 4220.

[0095] In this way, during the assembly process of the front plate 421 and the rear plate 422, positioning can be carried out through the first positioning ring 61, so as to ensure that the assembly position between the front plate 421 and the rear plate 422 is correct. Furthermore, it is ensured that the screw can be smoothly screwed into the first connecting portion 4211 on the front plate 421 and the second mounting hole 4221 on the rear plate 422, and the connection between the front plate 421 and the rear plate 422 is achieved.

[0096] In addition, it should be noted that the above-mentioned first positioning ring 61 abuts against the surrounding plate 4220 formed on the rear plate 422, and to a certain extent, it can also play a sealing role to prevent air in the air duct 30 from leaking through the gap between the front plate 421 and the rear plate 422.

[0097] It should be noted that the above-mentioned connecting surrounding plate 423 and the front plate 421 or the rear plate 422 can be integrally formed. For example, the connecting surrounding plate 423 can be integrally formed with the front plate 421 by die-casting.

[0098] In some embodiments of the present application, the above-mentioned connecting surrounding plate can also be integrally formed with the rear plate 422.

[0099] In some embodiments of the present application, as Figure 16 shown, a guiding portion 6 is formed on the surface of the rear plate 422 close to the ejector pipe. The guiding portion 6 is arranged around the nozzle avoidance hole 311 for one week. And the guiding portion 6 extends along the axis of the nozzle avoidance hole 311 towards the direction close to the inside of the ejector pipe 22.

[0100] The air flowing out from the air duct 30 can continue to flow along the extending direction of the guiding portion 6 after being sorted through the gap formed between the nozzle 23 and the nozzle avoidance hole 311, and the guiding portion 6 can further guide the air flowing along it.

[0101] It should be noted that the length of the above-mentioned flow guiding part 6 in the direction of the rear plate 422 pointing to the inside of the ejector tube 22 does not exceed the length of the nozzle 23 in the direction of the rear plate 422 pointing to the inside of the ejector tube 22, so as to ensure that the fuel ejected from the nozzle 23 is not affected by the air flowing along the flow guiding part 6.

[0102] In some embodiments, the length of the above-mentioned flow guiding part 6 in the direction of the rear plate 422 pointing to the inside of the ejector tube 22 can also exceed the length of the nozzle 23 in the direction of the rear plate 422 pointing to the inside of the ejector tube 22, so as to achieve a better guiding effect.

[0103] In some embodiments, the length of the above-mentioned flow guiding part 6 in the direction of the rear plate 422 pointing to the inside of the ejector tube 22 can also be equal to the length of the nozzle 23 in the direction of the rear plate 422 pointing to the inside of the ejector tube 22, so as to achieve a better guiding effect.

[0104] As Figure 16 shown, in some embodiments of the present application, the number of the air outlets 302 is multiple, and the air outlets 302 are arranged at intervals around the outer circumference of the flow guiding part 6.

[0105] In some embodiments, on one side around a nozzle mounting hole, the multiple air outlets 302 are distributed equidistantly or non-equidistantly.

[0106] In some embodiments, on one side around a nozzle mounting hole, the multiple air outlets 302 are horizontally distributed, vertically distributed, or annularly distributed.

[0107] In some embodiments, the air outlets 302 are set at different air outlet angles, so that the ejected air forms a swirling forward flow field around the nozzle, becoming swirling wind, which is beneficial to better mixing of the fuel gas and the air.

[0108] In certain embodiments, along the end of the air outlet 302 close to the ejector tube 22 to the end of the air outlet 302 far from the ejector tube 22, the air outlet 302 gradually moves away from the axis of the ejector tube 22, and the opening on the side of the air outlet 302 close to the ejector tube 22 and the opening on the side of the air outlet 302 far from the ejector tube 22 are arranged at intervals along the circumferential direction of the ejector tube 22.

[0109] In this case, if the axial direction of the burner head 21 is defined as the up-down direction, then along the end of the air outlet 302 close to the ejector tube 22 to the end of the air outlet 302 far from the ejector tube 22, the air outlet 302 gradually moves away from the axis of the ejector tube 22, which can be understood as the air outlet 302 being inclined in the up-down direction. Based on this, and the opening on the side of the air outlet 302 close to the ejector tube 22 and the opening on the side of the air outlet 302 far from the ejector tube 22 are arranged at intervals along the circumferential direction of the ejector tube 22, which can be understood as the air outlet 302 being inclined in the left-right direction.

[0110] In this way, the direction of the air flowing out of the air outlet 302 can have a certain swirling direction. Based on this, the air blown out from the air outlet 302 can form a swirling forward flow field, so that the air blown out from the air outlet 302 becomes swirling air. After the swirling air enters the ejector tube 22, the swirling air will rotate and flow forward along the inner wall of the ejector tube 22. Compared with the air flow that flows straight into the ejector tube 22 along the extension direction of the ejector tube 22, the air flow that enters the ejector tube 22 in a swirling manner can flow at a faster speed. The increase in the speed of the air flow is beneficial to the mixing of the air flow and the fuel in the ejector tube 22. In this way, setting the number of the air outlets 302 to be multiple can increase the supplement amount of the primary air. And arranging the multiple air outlets 302 around the outer periphery of the diversion part 6 can avoid the influence of the air flowing out of the air outlets 302 on the fuel ejected by the nozzle 23.

[0111] Next, the above-mentioned connecting member 41 will be described with reference to the accompanying drawings. As Figure 17 shown, the above-mentioned connecting member 41 includes a first connecting member 411, and one end of the first connecting member 411 is connected to the blower 32.

[0112] The above-mentioned connecting member 41 further includes a second connecting member 412, and one end of the second connecting member 412 is connected to the other end of the first connecting member 411. The other end of the second connecting member 412 is connected to the connection port 4230 of the connection shroud. And the inner diameter of the first connecting member 411 is smaller than the inner diameter of the second connecting member 412. It should be noted that the first connecting member 411 and the second connecting member 412 can be integrally formed by die casting.

[0113] In this way, when the air flows from the first connecting member 411 into the second connecting member 412, due to the sudden increase in the inner diameter, the flow rate of the air will decrease, and its static pressure will increase. In this case, it is beneficial for the air to be more evenly distributed in the second connecting member 412 of the connecting member 41. Further, the air flow entering the air duct 30 through the second connecting member 412 is also more uniform.

[0114] In order to enable the connecting member 41 to be connected to the air supply member 42, as Figure 17 shown, a third connecting portion 4231 is formed on the connection shroud 423, and a fourth connecting portion 4121 is formed at one end of the second connecting member 412 of the connecting member 41 close to the connection shroud 423. A third mounting hole 42310 is formed in the third connecting portion 4231, and a sixth mounting hole 41210 is formed in the fourth connecting portion 4121. Among them, the third mounting hole 42310 can be a threaded hole, and the fourth mounting hole 41210 can be a through hole. In this way, the screw can be passed through the third mounting hole 42310 and the fourth mounting hole 41210, and the screw is threadedly connected to the third mounting hole 42310, so as to connect the air supply member 42 and the connecting member 41.

[0115] In some embodiments of the present application, as Figure 17 shown, a second positioning ring 62 is formed on the rear plate 422. The second positioning ring 62 can extend into the interior of the ejector tube 22, and the second positioning ring can abut against the inner wall of the ejector tube 22 (see Figure 9 ).

[0116] It should be noted that the shape of the opening contour of the second positioning ring 62 matches that of the inlet of the ejector tube 22.

[0117] In this way, during the assembly of the air supply component 31 and the ejector tube 22, the second positioning ring 62 can be aligned with the opening of the ejector tube 22 to ensure that the air supply part 42 is aligned with the ejector tube 22, so as to ensure that the air supply part 42 and the ejector tube 22 can be properly installed when assembled.

[0118] In addition, the second positioning ring 62 abuts against the inner wall of the ejector tube 22, which can play a sealing role and reduce or avoid the leakage of the air flowing from the air supply part 42 into the ejector tube 22 between the air supply part 42 and the ejector tube 22.

[0119] It should be noted that when the above-mentioned first connecting member 411 is connected to the fan 32, as Figure 18 shown, at least part of the air outlet of the fan 32 overlaps and connects with the first connecting member 411, and the overlapping distance is greater than or equal to 3 mm. For example, it can overlap and connect by 3 mm, 4 mm, 5 mm, etc. That is, at least part of the air outlet of the fan 32 extends into the interior of the first connecting member 411 and the two abut against each other. In this way, it can ensure good sealing at the connection position between the fan 32 and the first connecting member 411 and avoid or reduce the leakage of the air blown out by the fan 32 to the outside.

[0120] In some embodiments of the present application, as Figure 19 shown, the air supply part 42 provided in the present application may further include a perforated plate 43. A plurality of through holes are formed in the perforated plate 43. The through holes may be uniformly arranged or non-uniformly arranged. The perforated plate 43 may be disposed between the air supply part 42 and the connecting member 41.

[0121] Referring to Figure 17 and Figure 19 , in order to enable the perforated plate 43 to be fixedly installed between the air supply part 42 and the connecting member 41, mounting through holes 4300 may also be formed in the perforated plate 43. The mounting through holes 4300 are coaxially arranged with the fifth mounting hole 42310 and the sixth mounting hole 41210. In this way, when using screws (or bolts) to pass through the fifth mounting hole 42310 and the sixth mounting hole 41210 to install the connecting member 41 and the air supply part 42, the perforated plate 43 can be fixedly installed together.

[0122] A plurality of through holes are formed in the porous plate 43 described above, which can play a role in buffering the flow, avoiding the air flow rate blown into the air duct 30 by the fan 32 from being too fast, resulting in the flame being lifted off. In addition, the through holes arranged at intervals can make the air enter the air duct 30 more evenly.

[0123] In the description of this specification, the specific features, structures, materials or characteristics may be combined in any one or more embodiments or examples in a suitable manner.

[0124] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
