Description

[0001] This application claims the priority of a Chinese patent application with the application number 202410969555.0 and the application title "A Gas Stove", which was filed with the National Intellectual Property Administration on July 18, 2024, and the entire content of which is incorporated herein by reference. Technical Field

[0002] The utility model relates to the technical field of cooking stoves, and particularly to a gas stove. Background Art

[0003] A gas stove refers to a kitchen appliance that uses gases such as liquefied petroleum gas, artificial gas, and natural gas as fuel for heating.

[0004] The main components of the most important combustion system in a gas stove include an ejector pipe, a spraying device, a burner head, and a burner cap. Fuel is sprayed into the ejector pipe through the spraying device. During the process of fuel being sprayed into the ejector pipe, the high-speed flowing fuel will entrain primary air, and the primary air and fuel enter the ejector pipe and mix. The primary air can provide oxygen for fuel combustion. However, the ability of the gas to naturally entrain primary air is limited, and when the primary air is insufficient, it will affect the thermal efficiency of the gas stove.

[0005] 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 primary air and fuel during natural entrainment. Therefore, the mixing effect of primary air and fuel is poor. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a gas stove, aiming to solve the problem of poor mixing effect of air and fuel when the blower device provides primary air.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The utility model provides a gas stove, which includes a burner head, an ejector pipe, a nozzle, and a air supply device. Among them, one end of the ejector pipe is connected to the burner head, and the nozzle is arranged at the other end of the ejector pipe.

[0009] The air supply device includes an air supply component, a blower, and a nozzle mounting part. Among them, the air supply component is arranged at the other end of the ejector pipe. An air duct is formed inside the air supply component, and an air inlet and an air outlet communicated with the air duct are provided. The air outlet is communicated with the inside of the ejector pipe. The blower is arranged at the air inlet and is connected to the air supply component. The nozzle is connected to the nozzle mounting part.

[0010] In this way, the blower can blow air into the air duct through the air inlet, and then the air in the air duct enters the inside of the ejector pipe communicated with it through the air outlet, realizing the supplement of primary air.

[0011] On this basis, the air supply component forms an avoidance channel with openings at both ends, and the interior of the avoidance channel is independent of the air duct. The above nozzle mounting member is arranged in the avoidance channel and is spaced from the inner wall of the avoidance channel to form a natural induction air inlet, and the natural induction air inlet is communicated with the interior of the induction pipe.

[0012] In this way, when the fan works to blow air into the air duct, then the air flows along the air duct and flows into the interior of the induction pipe from the air outlet to supplement the primary air. At the same time, the nozzle is arranged in the avoidance channel through the nozzle mounting member and is coaxially arranged with the air outlet. When the nozzle sprays fuel into the interior of the induction pipe, air can also be induced through the natural induction air inlet formed between the nozzle mounting member and the inner wall of the avoidance channel. During the process of the gas jet inducing air through the natural induction air inlet, the fuel can contact and mix with the air, thus making up for the lack of the mixing process in the natural induction process when the fan directly blows air into the induction pipe. Thereby, the problem of poor mixing effect of fuel and air when blowing air into the induction pipe through the air blowing device is solved.

[0013] In some embodiments, the air supply component includes a housing and a wind guiding ring. Among them, the interior of the housing forms an air duct, and an avoidance hole and an air outlet are formed on the housing. The wind guiding ring is located in the air duct, and the wind guiding ring encloses an avoidance channel. One end of the wind guiding ring is arranged around the periphery of the avoidance hole for one week and is connected to the inner wall of the housing; the other end of the wind guiding ring is located inside the air outlet and is spaced from the inner wall of the air outlet.

[0014] In some embodiments, the housing includes a front plate, a rear plate and a surrounding plate. Among them, the front plate covers the other end of the induction pipe, and an air outlet is formed on the front plate, and the air outlet is arranged opposite to the other end of the induction pipe. The rear plate is located on the side of the front plate away from the induction pipe, and an avoidance hole is formed on the rear plate, and the avoidance hole is arranged opposite to the air outlet, and an air inlet is formed on the rear plate. The wind guiding ring is located on the side of the rear plate close to the front plate, and one end of the wind guiding ring is arranged around the periphery of the avoidance hole for one week, and the wind guiding ring is connected to the rear plate. The surrounding plate is located between the front plate and the rear plate, and the surrounding plate is connected to the front plate and the surrounding plate is connected to the rear plate. The front plate, the rear plate and the surrounding plate enclose the air duct.

[0015] In some embodiments, the gas stove further includes a connecting rib. The connecting rib is located in the avoidance channel, one end of the connecting rib is connected to the inner wall of the avoidance channel, and the other end of the connecting rib is connected to the nozzle mounting member.

[0016] In some embodiments, the number of the connecting ribs can be multiple, and the multiple connecting ribs are arranged at intervals along the circumferential direction of the nozzle mounting member.

[0017] In some embodiments, along the axis of the wind guiding ring, in the direction of the rear plate pointing to the front plate, the outer diameter of the wind guiding ring gradually decreases.

[0018] In some embodiments, a first positioning ring is formed on a surface of the front plate close to the ejector tube. The first positioning ring can extend into the interior of the ejector tube and abut against the inner wall of the ejector tube. The air outlet is located inside the first positioning ring.

[0019] In some embodiments, a second positioning ring is formed on a surface of the rear plate close to the front plate. The second positioning ring is arranged along the circumferential direction of the rear plate, and the second positioning ring can abut against the surrounding plate.

[0020] In some embodiments, a wind guiding portion is formed on a surface of the front plate close to the ejector tube. The wind guiding portion is arranged around the air outlet for one week. Along the axis of the ejector tube, in the direction from the rear plate to the front plate, compared with one end of the nozzle close to the ejector tube, one ends of the wind guiding portion and the wind guiding ring close to the ejector tube are closer to the burner head.

[0021] In some embodiments, the air supply device further includes a fan connecting member. One end of the fan connecting member is connected to the air inlet, and the other end is communicated with the fan. The fan is communicated with the air inlet through the fan connecting member. A connecting channel is formed inside the fan connecting member. One end of the connecting channel is communicated with the fan, and the other end is communicated with the air duct.

[0055] When selecting a gas stove, high efficiency and energy conservation are important factors of concern. Therefore, the continuous breakthrough of high efficiency of gas stoves is an important topic in the industry. To improve the thermal efficiency of a gas stove, a heat collecting plate can be used to reduce heat dissipation; or the height of the combustion flame can be reduced to make the distance between the bottom of the pot and the burner closer, reducing the space for heat dissipation, thereby reducing heat loss and improving energy efficiency. The air used for gas combustion in a gas stove is generally provided in two parts. One part is mixed with the gas before combustion and is called primary air. After the mixture of gas and primary air is ejected from the flame holes of the burner cap, it is further mixed with the air in the environment and then burns. The air in the environment participating in combustion is called secondary air. The primary air determines the flame height. The more primary air there is, the lower the flame height. Therefore, to reduce the flame height, the content of primary air needs to be increased.

[0056] Specifically, the main components of the combustion system in a gas stove include an ejector pipe, a spraying device, a burner head and a burner cap. The fuel is sprayed into the ejector pipe through the spraying device. During the process of the fuel being sprayed into the ejector pipe, the fuel flowing at high speed will eject the primary air. The primary air and the fuel enter the ejector pipe and are mixed, and the primary air can provide oxygen for fuel combustion. However, the ability of the gas to naturally eject the primary air is limited, and insufficient primary air will affect the thermal efficiency of the gas stove. In the conventional structure, the kinetic energy of the gas itself during spraying is relied on to eject the primary air, and the amount of the ejected primary air is limited.

[0057] To solve the problem of insufficient primary air, in the related art, it is proposed to blow primary air into the ejector tube through a blower device. However, in the related art, blowing primary air into the ejector tube through a blower device lacks the mixing process when the gas naturally ejects primary air, and the air directly blown into the ejector tube by the blower device easily affects the gas ejected from the nozzle. Based on these problems existing in the related art, the structure of a gas stove with a blower device of the present application will be introduced next.

[0058] Figure 1 Schematic diagram of a gas stove 100 provided by the present application.

[0059] The present application provides a gas stove, as Figure 1 shown, the gas stove 100 includes a housing 11, and the housing 11 forms an installation cavity 10 with an opening.

[0060] The opening is communicated with the installation cavity 10 so that other related components of the gas stove 100 can be installed in the installation cavity 10 of the housing 11.

[0061] The housing 11 can provide support for the related components installed in its installation cavity 10 and a certain degree of protection to prevent other related components of the gas stove 100 from being damaged.

[0062] As Figure 1 shown, the gas stove 100 provided by the present application further includes a burner head 21, and the burner head 21 is arranged in the installation cavity 10 of the housing 11. The burner head 21 forms an annular cavity with an opening, and through the burner head 21, the fuel and the primary air can be mixed in a certain way.

[0063] Continuing to refer to Figure 1 , the gas stove 100 provided by the present application further includes a panel 12, and the panel 12 can cover the opening of the housing 11, and the panel 12 is used to seal the installation cavity 10 of the housing 11. In this way, the panel 12 can prevent sundries or food residues dropped during cooking from falling into the installation cavity 10 of the housing 11, thereby ensuring that other components arranged in the installation cavity 10 are not damaged or polluted, and further ensuring that the gas stove 100 can work properly.

[0064] In this case, as Figure 1 shown, an avoidance opening 120 is further provided on the above-mentioned panel 12. The burner head 21 is arranged opposite to the avoidance opening 120 provided on the panel 12, so that the burner head 21 can be located within the opening range of the avoidance opening 120 of the panel 12. In this way, when the burner head 21 burns fuel to generate a flame, the panel 12 will not block the flame generated by the burner head 21 burning fuel, ensuring that the burner head 212 can work properly, enabling the flame to heat the bottom of the cookware, so that the user can cook.

[0065] As described above, a gas stove 100 provided by an embodiment of the present application includes a housing 11, a panel 12, and a burner head 21. Among them, the burner 2 can be installed in the installation cavity 10 of the housing 11, and then the installation cavity 10 of the housing 11 is covered by the panel 12 to protect other components arranged in the installation cavity 10, ensuring that the burner head 21 and other components are not damaged, so as to ensure that the gas stove 100 can work properly.

[0066] In some embodiments, the gas stove 100 provided by the present application may further include a burner cap assembly, and the burner cap assembly is covered on the burner head 21. A burner hole is formed on the burner cap assembly, and the burner hole communicates with the annular cavity of the burner head 21. In this way, the primary air and fuel that are mixed in the burner head 21 can flow out from the burner holes of the burner cap assembly covered on the burner head 21, and then be ignited to form a flame, and the flame heats the bottom of the cookware for the user to cook.

[0067] As Figure 2 shown, in certain embodiments, the gas stove 100 provided by the present application includes an ejector tube 22, and one end of the ejector tube 22 is connected to the burner head 21. The fuel and the primary air can enter the burner head 21 through the ejector tube 22 and continue to be mixed in the burner head 21.

[0068] In order to enable the fuel to enter the ejector tube 22 and then enter the burner head 21 through the ejector tube 22. In certain embodiments of the present application, as Figure 3 shown, the gas stove 100 provided by the present application includes a nozzle 23, and the nozzle 23 is arranged at the other end of the ejector tube 22.

[0069] In this way, the gas supply pipeline is connected to the other end of the nozzle 23 (that is, the end of the nozzle 23 away from the ejector tube 22), and the fuel can be ejected through the nozzle 23. The gas jet ejected from the nozzle 23 can enter the ejector tube, and at the same time the gas jet can entrain the air near the nozzle 23, and the entrained air serves as the primary air and enters the ejector tube 22 together with the fuel, and the primary air and the fuel can be mixed in the ejector tube 22.

[0070] The process of the above-mentioned gas jet ejecting into the ejector tube 22 and entraining the primary air is called natural entrainment. When the gas is ejected from the nozzle 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 gas jet, thereby attracting the nearby air, so that the nearby air enters the ejector tube together with the gas jet.

[0071] It should be noted that the amount of primary air affects the height of the flame at the flame outlet. When the content of primary air is relatively large compared to the case where the content of primary air is relatively small, the height of the flame at the flame outlet is smaller when the content of primary air is relatively large than when the content of primary air is relatively small. In the case where insufficient primary air leads to an increase in the flame height, in order to ensure complete combustion of the fuel and qualified flue gas indicators, it is necessary to increase the distance between the bottom of the cookware and the burner cap, which will increase the loss of flame heat, thereby resulting in a decrease in the thermal efficiency of the gas stove.

[0072] 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 loss of the flame. However, the natural entrainment ability of the gas jet is limited. When the gas naturally entrains primary air to the limit and the primary air still cannot enable complete combustion of the gas, in order to achieve complete combustion of the gas and ensure qualified flue gas indicators, it is necessary to increase the distance between the cookware and the burner cap, and thus the above problem of reduced thermal efficiency of the gas stove will occur.

[0073] In some embodiments of the present application, as Figure 4 shown, the gas stove provided by the present application includes an air supply device, and the air supply device includes a air supply component 31.

[0074] The air supply component 31 is arranged at the other end of the ejector tube 22. As Figure 5 shown, an air duct 30 is formed inside the air supply component 31.

[0075] As Figure 6 shown, the air supply component 31 is provided with an air inlet 311 and an air outlet 312 that communicate with the air duct 30, and both the air inlet 311 and the air outlet 312 communicate with the air duct 30.

[0076] Among them, the air outlet 312 communicates with the inside of the ejector tube 22, so that the air in the air duct 30 can enter the ejector tube 22 through the air outlet 312 to achieve the purpose of supplementing primary air.

[0077] On this basis, as Figure 7 shown, the air supply device provided by the present application further includes a blower 32.

[0078] The blower 32 is arranged at the air inlet 311 of the air supply component 31, and the blower 32 is connected to the air supply component 31.

[0079] Next, in combination with the accompanying drawings, the air supply component 31 will be further described. As Figure 8 shown, the air supply component 31 forms an avoidance channel 400 with openings at both ends. The inside of the avoidance channel 400 is independent of the air duct 30, and the avoidance channel 400 communicates with the inside of the ejector tube 22.

[0080] On this basis, asFigure 9 As shown, the air supply component 31 provided in the present application further includes a nozzle mounting member 33, and the nozzle 23 is connected to the nozzle mounting member 33. The nozzle mounting member 33 is disposed in the avoidance passage 400. In this way, the nozzle 23 can be arranged at the other end of the ejector tube 22 through the nozzle mounting member 33, so that the nozzle 23 can inject fuel into the ejector tube 22.

[0081] It should be noted that threaded holes can be formed in the above-mentioned nozzle mounting member 33, and the threaded holes are coaxial with the ejector tube 22. In this way, the nozzle 23 can be connected to the nozzle mounting member 33 by being threadedly connected to the threaded holes of the nozzle mounting member.

[0082] See Figure 10 , the above-mentioned nozzle mounting member 33 is spaced from the inner wall of the avoidance passage to form a natural induction air inlet 500, and the natural induction air inlet 500 is communicated with the inside of the ejector tube 22.

[0083] In this way, when the nozzle 23 injects fuel, the negative pressure area formed near the gas jet can suck the air near the nozzle 23 into the ejector tube 22 through the natural induction air inlet 500 and enter the ejector tube 22 together with the fuel. And in this process, the fuel and the air can come into contact and mix, thus solving the problem that the fuel and the air are not sufficiently mixed when the air blowing device directly blows air into the ejector tube 22.

[0084] In addition, the natural induction air inlet 500 formed by the spaced arrangement between the nozzle mounting member 33 and the inner wall of the avoidance passage 400 is annular, which can better equalize the pressure of the naturally induced primary air and at the same time disperse the air flow around the nozzle 23, which is more conducive to the mixing of the naturally induced primary air and the gas.

[0085] As Figure 11 shown, in some embodiments of the present application, an induction hole 230 is further formed in the nozzle 23. When the nozzle 23 injects fuel into the ejector tube 22, the fuel flowing at a high speed in the nozzle 23 can also induce the air near the nozzle 23 through the induction hole 230 formed in the nozzle 23. Further, it serves the purpose of supplementing the primary air.

[0086] As can be seen from the above, the gas stove provided in the present application includes an air supply device. The air supply device can enable the gas stove to blow air into the ejector tube 22 through the air supply component 31, the blower 32 and the nozzle mounting member 33 to supplement the primary air, and at the same time can also use the natural induction of air by fuel as the primary air, improving the mixing efficiency of the fuel and the primary air during the natural induction process, and thus solving the problem that the air supply device mixes poorly with the fuel in the related art.

[0087] Next, the air supply component 31 will be further described with reference to the accompanying drawings. As Figure 12 shown, the air supply component 31 includes a housing 310. A duct 30 is formed inside the housing 310, and an avoidance hole 4000 and an air outlet 312 are formed in the housing 310. In some embodiments, the avoidance hole 4000 and the air outlet 312 may be oppositely arranged.

[0088] On this basis, as Figure 13 shown, the air supply component 31 further includes a wind guide ring 3100.

[0089] The wind guide ring 3100 is located in the duct, and the wind guide ring 3100 encloses an avoidance passage 400. Based on this, one end of the wind guide ring 3100 is arranged around the periphery of the avoidance hole 4000 for one week and is connected to the inner wall of the housing 310. As Figure 14 shown, the other end of the wind guide ring 3100 is located inside the air outlet 312 and is spaced from the inner wall of the air outlet 312.

[0090] In this way, the wind guide ring 3100 is located inside the air outlet 312 and is spaced from the inner wall of the air outlet 312. In this way, an annular air outlet communicating with the duct 30 is formed between the air outlet 312 and the wind guide ring 3100. And this annular air outlet is formed around the nozzle 23. In this way, when the fuel is ejected from the nozzle 23, to a certain extent, it can also eject the air flowing out from the annular air outlet and mix with it, further improving the mixing effect of the fuel and the air.

[0091] As Figure 12 shown, the above-mentioned housing 310 includes a front plate 3101. The front plate 3101 covers the other end of the injection pipe 22, and an air outlet 312 is formed in the front plate 3101. The air outlet 312 is oppositely arranged with the other end of the injection pipe 22. In this way, the air in the duct 30 can smoothly enter the inside of the injection pipe 22 through the air outlet 312 to achieve the purpose of supplementing the primary air.

[0092] As Figure 12 shown, the above-mentioned housing 310 further includes a rear plate 3102. The rear plate 3102 is located on the side of the front plate 3101 away from the injection pipe 22. An avoidance hole 4000 is formed in the rear plate 3102, and the avoidance hole 4000 is oppositely arranged with the air outlet 312. In some embodiments, the avoidance hole 4000 and the air outlet 312 may be coaxially arranged. In addition, it should be noted that an air inlet 311 is formed in the rear plate 3102.

[0093] As Figure 15As shown in the figure, the air supply device provided by the present application further includes a fan connecting member 320. One end of the fan connecting member 320 is connected to the air inlet 311, and the other end is connected to the fan 32. The fan 32 is communicated with the air inlet 311 through the fan connecting member 320. And a connecting channel 3200 is formed inside the fan connecting member 320. One end of the connecting channel 3200 is communicated with the fan 32, and the other end is communicated with the air duct 30, so that the fan 32 can input air into the air duct 30 through the connecting channel 3200 of the connecting member 320.

[0094] As Figure 16 shown, in some embodiments of the present application, the connection part between the fan connecting member 320 and the fan 32 is overlapped. The overlapping distance ≥ 3mm. For example, the overlapping distance can be 3mm, 4mm or 5mm, etc.

[0095] In this way, the sealing effect of the connection position between the fan connecting member 320 and the fan 32 can be ensured. In addition, in the air outlet direction of the fan 32, the channel area of the connecting channel 3200 of the fan connecting member 320 is smaller than the channel area of the air duct 30. In this way, the air blown into the fan 32 first enters the connecting channel 3200 with a relatively small channel area, and then flows into the air duct 30 with a larger channel area. The flow rate of the air flow will decrease, and the air flow can be more evenly distributed in the air duct 30, so that it can flow out more evenly from the air outlet 312, and the air flow can flow more evenly into the interior of the injection pipe 22, which is beneficial to the mixing of air and fuel.

[0096] Continue to refer to Figure 13 , the air guiding ring 3100 is located on the side of the rear plate 3102 close to the front plate 3101. One end of the air guiding ring 3100 is arranged around the periphery of the avoidance hole 4000, and the air guiding ring 3100 is connected to the rear plate 3102.

[0097] On this basis, as Figure 12 shown, the housing 310 further includes a surrounding plate 3103. The surrounding plate 3103 is located between the front plate 3101 and the rear plate 3102. And the surrounding plate 3103 is connected to the front plate 3101, and the surrounding plate 3103 is also connected to the rear plate 3102. Based on this, the front plate 3101, the rear plate 3102 and the surrounding plate 3103 enclose the air duct 30.

[0098] The above-mentioned front plate 3101, rear plate 3102 and surrounding plate 3103 can be formed by casting. Among them, the surrounding plate 3103 can be integrally formed with the front plate 3101, or in some other embodiments, the surrounding plate 3103 can be integrally formed with the rear plate 3102.

[0099] As Figure 17As shown, in some embodiments of the present application, a wind guiding portion 7 is formed on a surface of the front plate 3101 close to the ejector tube 22, and the wind guiding portion 7 is arranged around the air outlet 312 for one week.

[0100] In this way, when the air in the air duct 30 flows out from the air outlet 312, the air flow can continue to flow along the inner wall of the wind guiding portion 7 for a certain distance, so as to comb the air flow flowing out from the air outlet 312.

[0101] In addition, along the axis of the ejector tube 22, in the direction from the rear plate 3102 to the front plate 3101, the end of the nozzle 23 close to the ejector tube 22 is closer to the burner head 21 than the end of the wind guiding portion 7 close to the ejector tube 22 and the end of the wind guiding ring 3100 close to the ejector tube 22. That is, on the axis of the ejector tube 22, the ejector tube 22 can extend along the direction close to the ejector tube 22 and expose outside the wind guiding portion 7 and the wind guiding ring 3100.

[0102] In some embodiments, the nozzle 23 can also be located behind the wind guiding portion 7 and the wind guiding ring 3100, that is, the nozzle 23 does not extend out of the wind guiding portion 7 and the wind guiding ring 3100.

[0103] In this way, the air flowing out between the wind guiding ring 3100 and the air outlet 312 has the least influence on the gas flow ejected by the nozzle 23, and is convenient for the mixing of air and gas flow.

[0104] In some embodiments, along the axis of the ejector tube 22, in the direction from the rear plate 3102 to the front plate 3101, the wind guiding portion 7 is flush with the wind guiding ring 3100, and the nozzle 23 slightly protrudes from the wind guiding portion 7 and the wind guiding ring 3100, which is more conducive to the mixing of gas jet and air.

[0105] As Figure 13 shown, in some embodiments of the present application, the gas stove 100 further includes a connecting rib 5. The connecting rib 5 is located in the avoidance channel 400, and one end of the connecting rib 5 is connected to the inner wall of the avoidance channel 400, and the other end of the connecting rib 5 is connected to the nozzle mounting member 33.

[0106] In this way, the nozzle mounting member 33 is arranged in the avoidance channel 400 through the above-mentioned connecting rib 5, connected to the avoidance channel 400 and arranged at intervals. The connecting rib 5 plays a role in supporting the nozzle mounting member 33.

[0107] The above-mentioned connecting rib 5 can be integrally formed by die casting with the nozzle mounting member 33 and the air supply component 31, or can be separately formed and then connected into one body by welding.

[0108] In some embodiments of the present application, the number of the above-mentioned connecting ribs 5 can also be multiple, and the multiple connecting ribs 5 are arranged at intervals along the circumferential direction of the nozzle mounting member 33. For example, the number of the connecting ribs 5 can be four (seeFigure 12 ) Four connecting ribs 5 are arranged at circumferential intervals along the nozzle mounting member 33.

[0109] It should be noted that the above-mentioned multiple connecting ribs 5 can be arranged at equal intervals or at unequal intervals.

[0110] In this way, by arranging multiple connecting ribs 5 at circumferential intervals along the nozzle mounting member 33, the multiple connecting ribs 5 can simultaneously support and fix the nozzle mounting member 33, and the multiple connecting ribs 5 can better support the nozzle mounting member 33.

[0111] On the other hand, when the primary air entrained by the gas jet flows from the natural air inlet 500 formed between the nozzle mounting member 33 and the avoidance channel 400 into the entrainment pipe 22, the air entrained by the gas jet will flow through the multiple connecting ribs 5 provided between the nozzle mounting member 33 and the avoidance channel 400. The air flowing through the multiple connecting ribs 5 will come into contact with the surface of the connecting ribs 5 and flow along the surface of the connecting ribs 5. Based on this, the multiple connecting ribs 5 can guide the air, and the multiple connecting ribs 5 can play a role in combing the air flow direction, making the air flow to be introduced into the entrainment pipe 22 more stable and reducing its influence on the gas jet.

[0112] As Figure 18 shown, in some embodiments of the present application, along the axis of the air guiding ring 3100, in the direction in which the rear plate 3102 points to the front plate 3101, the outer diameter of the air guiding ring 3100 gradually decreases.

[0113] In this way, the air guiding ring 3100 has a combing and guiding effect on the air flow flowing through its surface, and can make the air flow flow along the periphery of the nozzle 23, and the flow direction is the same as the direction of the gas jet ejected from the nozzle 23. And the air guiding ring 3100 can guide the air flow flowing through its surface to concentrate in the axial direction, which is beneficial to the gas air flow and the air air flow entering the interior of the entrainment pipe 22 more quickly.

[0114] For example, when the fan 32 works to blow air into the air duct 30 of the air supply assembly 31, when the air in the air duct 30 flows out from the annular air outlet formed between the nozzle air guiding ring 3100 and the air outlet 312, the air will flow along the surface of the air guiding ring 3100 and the inner ring surface of the air guiding portion 7, so as to achieve the purpose of combing the air flow direction. On this basis, the outer diameter of the air guiding ring 3100 gradually decreases in the direction in which the rear plate 3102 points to the front plate 3101. Furthermore, in the direction in which the rear plate 3102 points to the front plate 3101, the distance between the surface of the air guiding ring 3100 and the axis of the air guiding ring 3100 becomes smaller and smaller. It can be understood that when the air guiding ring 3100 is coaxially arranged with the entrainment pipe 22, the distance between the surface of the air guiding ring 3100 and the axis of the entrainment pipe 22 also becomes smaller and smaller.

[0115] Therefore, the air flow flowing along the surface of the air guide ring 3100 is concentrated in the direction close to the axis of the ejector tube 22 under the guiding action of the air guide ring 3100 and the air guiding part 7. In this way, it can reduce the contact between the air flow and the tube wall at the inlet of the ejector tube 22, but directly flow into the throat of the ejector tube 22, thereby reducing the loss of air flow velocity and enabling the air flow to enter the interior of the ejector tube 22 more quickly.

[0116] In some embodiments of the present application, along the axis of the air guide ring 3100, in the direction where the rear plate 3102 points to the front plate 3101, the inner diameter of the air guiding part 7 gradually decreases, and the air guiding part 7 is conical. In this way, the inner diameters of the air guiding part 7 and the air guide ring 3100 both gradually decrease in the same direction, and the two can cooperate better to play a role in guiding the air flow.

[0117] In some embodiments, the above-mentioned air guide ring 3100 can also be a hollow cylindrical shape, that is, along the axis of the air guide ring 3100, in the direction where the rear plate 3102 points to the front plate 3101, the inner diameter of the air guide ring 3100 remains unchanged. In this case, the surface of the air guide ring 3100 can also play a role in combing and guiding the air flow passing through its surface.

[0118] Based on this, the air guiding part 7 can also be cylindrical. Similarly, along the axis of the air guide ring 3100, in the direction where the rear plate 3102 points to the front plate 3101, the inner diameter of the air guiding part 7 remains unchanged.

[0119] As Figure 6 shown, a first positioning ring 61 is formed on the surface of the front plate 3101 close to the ejector tube 22. The first positioning ring 61 can extend into the interior of the ejector tube 22 and abut against the inner wall of the ejector tube 22.

[0120] In this way, during the process of covering the front plate 3101 on the ejector tube 22, or when assembling the air supply component 31 with the ejector tube 22. The first positioning ring 61 can play a guiding role, ensuring that the front plate 3101 and the ejector tube 22 are assembled in place, and ensuring that the air outlet 312 opened on the front plate 3101 and the air guide ring 3100 or other components arranged in the air outlet 312 are coaxially arranged with the ejector tube 22, ensuring that it can achieve the best effect.

[0121] In addition, the abutment of the first positioning ring 61 against the inside of the ejector tube 22 (see Figure 4 ) can also play a role in strengthening the sealing effect between the front plate 3101 and the ejector tube 22 to a certain extent. And the air outlet 312 is located inside the first positioning ring 61 to ensure that when the first positioning ring 61 abuts against the inside of the ejector tube 22, it can effectively play a role in improving the sealing effect.

[0122] As Figure 13 and Figure 14 shown, in some embodiments of the present application, a second positioning ring 62 is formed on a surface of the rear plate 3102 close to the front plate 3101. The second positioning ring 62 is arranged along the circumferential direction of the rear plate 3102, and the second positioning ring 62 can abut against the surrounding plate 3103.

[0123] In this way, during the assembly process of the air supply assembly 31, when the rear plate 3102 and the front plate 3101 are assembled, the second positioning ring 62 can ensure that the rear plate 3102 and the front plate 3101 are assembled in place through the guiding and positioning function of the second positioning ring 62. And the second positioning ring 62 can abut against the surrounding plate 3103. In this way, a sealing effect can be achieved, ensuring that the air duct 30 surrounded by the front plate 3101, the rear plate 3102, and the surrounding plate 3103 can have better sealing performance, preventing the air blown into the air duct 30 by the fan 32 from leaking, and ensuring that the air blown into the air duct 30 by the fan 32 can enter the inside of the injection pipe 22.
