The connecting port can be round, the round connecting port is more matched with a conventional pipeline, and an auxiliary air channel with the round connecting port is easier to install. The diameter of the connecting port can be not smaller than 3mm, so that the influence of the too small diameter of the connecting port on the flow effect of the fuel gas in the auxiliary gas channel is avoided.
The first connecting section extends from the connecting port along the axial direction of the first connecting section to form a third connecting section, an opening for communicating the outside is formed at one end of the third connecting section away from the first connecting section, and a plug is arranged at the opening.

Illustratively, the connection port and the opening have a distance L therebetween, L being 8mm to 20mm. The distance L can prevent the plug from forming flow limitation on the auxiliary gas channel due to the fact that the distance between the connecting port and the opening is too small, and therefore the gas with enough flow in the auxiliary gas channel is ensured. And such a distance L can avoid excessive space occupation of the whole device due to excessive distance between the connection port and the opening.

An inner annular fire passage 110 may be formed between the air inlet 140 and the inner annular fire air outlet 150, and an outer annular fire passage 120 may be formed between the air inlet 140 and the outer annular fire air outlet 160. The auxiliary gas passage 130 may be communicated with the inner annular flame passage 110 and/or the outer annular flame passage 120, as shown in fig. 4, an auxiliary gas inlet 131 may be provided on the outer annular flame passage 120, an auxiliary gas outlet 132 may be provided on the inner annular flame passage 110, and the auxiliary gas passage 130 may be formed between the auxiliary gas inlet 131 and the auxiliary gas outlet 132. In other embodiments, the auxiliary gas channel 130 may be in the form of one branch provided on the inner annular fire channel 110, or may be in the form of one branch provided on the outer annular fire channel 120, for example, the auxiliary gas channel 130 is one branch provided on the inner annular fire channel 110, as shown in fig. 7, an auxiliary gas inlet 131 and an auxiliary gas outlet 132 are provided on the inner annular fire channel 110, the auxiliary gas inlet 131 is closer to the gas inlet 140 than the auxiliary gas outlet 132, and the auxiliary gas channel 130 is formed between the auxiliary gas inlet 131 and the auxiliary gas outlet 132.
The function of the auxiliary gas channel 130 is described in the embodiments shown in fig. 2, 3 and 4. In normal use of the stove, fuel gas continuously enters the connecting body 100 from the gas inlet 140, the fuel gas entering the connecting body 100 firstly enters the inner annular fire channel 110 and the outer annular fire channel 120, part of the fuel gas entering the outer annular fire channel 120 enters the auxiliary gas channel 130 through the auxiliary gas inlet 131 and then enters the inner annular fire channel 110 through the auxiliary gas outlet 132, and the gas at the gas inlet 140 can be continuously replenished and can be regarded as being full of fuel gas everywhere in the connecting body 100, so that the fuel gas in the auxiliary gas channel 130 is collected into the inner annular fire channel 110, and the replenishment of the fuel gas on the inner annular fire channel 110 is actually formed, so that the amount of the fuel gas reaching the inner annular fire gas outlet 150 on the inner annular fire channel 110 is increased, and the final gas outlet amount of the inner annular fire channel 110 is also increased.
The auxiliary gas channel 130 may be provided with a control valve 200, which control valve 200 may be manually operated or may be electronically controlled, for an electronically controlled control valve 200, the control valve 200 typically needs to be connected to an external controller. The control valve 200 may include a valve body 210 and an adjustment member 220 movable between a first position and a second position, the valve body 210 may be located outside the connection body 100, the adjustment member 220 may be movably connected to the valve body 210 and movable between the first position and the second position, wherein the auxiliary gas passage 130 may be in a closed state when the adjustment member 220 is located at the first position, and the auxiliary gas passage 130 may be in a conductive state to increase the gas outlet amount of the inner ring fire passage 110 and/or the gas outlet amount of the outer ring fire passage 120 when the adjustment member 220 is located at the second position. When the adjusting member 220 is located at the first position, the adjusting member 220 may block the auxiliary air channel 130, and when the adjusting member 220 is located at the second position, the blocking of the auxiliary air channel 130 by the adjusting member 220 may be at least partially opened. In the embodiment in which the auxiliary gas channel 130 is connected between the inner ring fire channel 110 and the outer ring fire channel 120, the plugging of the auxiliary gas channel 130 by the adjusting member 220 in the second position at least partially opens, which may result in an increase in the amount of gas output from the channel in which the auxiliary gas outlet 132 is located, for example, in the embodiment shown in fig. 4, the auxiliary gas channel 130 is in a conducting state by the adjusting member 220 in the second position, and since the auxiliary gas inlet 131 is disposed on the outer ring fire channel 120, the auxiliary gas outlet 132 is disposed on the inner ring fire channel 110, and the final amount of gas output from the inner ring fire channel 110 is increased by the auxiliary gas channel 130 in the conducting state; similar to the embodiment in which the auxiliary gas inlet 131 is provided in the inner annular flame path 110 and the auxiliary gas outlet 132 is provided in the outer annular flame path 120, a detailed description thereof will be omitted. In an embodiment in which the auxiliary gas channel 130 is a branch provided on the inner annular fire channel 110 or the outer annular fire channel 120, for example, as shown in fig. 7, the auxiliary gas inlet 131 and the auxiliary gas outlet 132 are both provided on the inner annular fire channel 110, and when the adjusting member 220 located at the second position makes the auxiliary gas channel 130 be in a conducting state, the final gas outlet amount of the inner annular fire channel 110 can be increased; the auxiliary gas inlet 131 and the auxiliary gas outlet 132 are disposed on the outer ring fire passage 120 similarly, and are not described herein. Of course, in the embodiment not shown, it is also possible to provide the auxiliary gas passages 130 in the form of one branch on each of the inner ring fire passage 110 and the outer ring fire passage 120, so that the final gas output of both the inner ring fire passage 110 and the outer ring fire passage 120 is increased when both the auxiliary gas passages 130 are in the on state.
The gas may pass through the auxiliary gas channel 130 in the conducting state, but the conducting state of the auxiliary gas channel 130 does not mean that the auxiliary gas channel 130 is not restricted to the gas, for example, when the adjusting member 220 is located in the second position, half of the cross section of the auxiliary gas channel 130 can be blocked, so that only half of the cross section of the auxiliary gas channel 130 where the adjusting member 220 is located can pass through the gas, and the other half can form a restriction to the gas, and the auxiliary gas channel 130 is also in the conducting state. In other words, the on state of the auxiliary gas channel 130 does not mean that the auxiliary gas channel 130 is defined to be in the fully opened state, and any opening degree corresponding to the auxiliary gas channel 130 in the on state is within the scope of the present utility model. In another aspect, the present utility model does not limit the control valve 200 to only control the auxiliary air channel 130 to switch between the full open state and the full closed state, and in the air intake assembly provided by the present utility model, the control valve 200 can control not only the auxiliary air channel 130 to be completely closed and in the closed state, but also the opening degree of the auxiliary air channel 130 to be in the on state. Preferably, the control valve 200 controls the auxiliary gas channel 130 to switch between a fully open conductive state and a fully closed state, i.e. when the auxiliary gas channel 130 is in the conductive state, the auxiliary gas channel 130 is in a substantially fully open state, i.e. the flow area of the fuel gas flowing in the auxiliary gas channel 130 in the conductive state, i.e. the cross-sectional area of the auxiliary gas channel 130.
The inner annular flame path 110 and the outer annular flame path 120 may lie in a first plane. It will be appreciated that since the inner and outer annular flame paths 110, 120 have a certain volume, the first plane referred to herein is not strictly a plane, and may have a certain thickness. The connection between the first position and the second position may be located on a second plane, and the second plane and the first plane may satisfy a parallel condition (where the satisfaction of the parallel condition means that the second plane and the first plane are parallel within a tolerance allowable range). It will be appreciated that the second plane may also be of a certain thickness, similar to the first plane. The first plane and the second plane satisfying the parallelism condition are actually two planes with a space therebetween, or, the first plane and the second plane are not coplanar. The connection line between the first position and the second position is located on the second plane, that is, the plane on which the movement track is located when the adjusting member 220 moves between the first position and the second position is parallel to the first plane. Typically, when the air intake assembly is mounted to a cooktop, the first plane is parallel to the horizontal plane, and the trajectory of movement of the adjustment member 220 is on a second plane parallel to the horizontal plane. Taking the example of a self-priming valve in which the adjustment member 220 is telescopic relative to the valve body 210, such a control valve 200 may in fact be considered to be transverse, with the adjustment member 220 being telescopically movable relative to the valve body 210 in a second plane parallel to the horizontal plane. The lateral control valve 200 is smaller in dimension in the height direction. Of course, such a control valve 200 is smaller in size in a direction perpendicular to the first plane and the second plane, similar to the first plane, which is not parallel to the horizontal plane.
The air inlet assembly provided by the utility model can realize strong fire stir-frying according to the needs of users by being provided with the auxiliary air channel 130 and the control valve 200. And the second plane on which the movement track of the adjusting member 220 between the first position and the second position is located is parallel to the first plane, the size of the control valve 200 in the direction perpendicular to the first plane and the second plane is smaller, the size of the whole air inlet assembly in the direction perpendicular to the first plane and the second plane is smaller, and the air inlet assembly occupies a small space in the direction perpendicular to the first plane and the second plane, and is easy to install. In the usual case of a first plane parallel to the horizontal plane, such an air intake assembly is smaller in size in the vertical direction, occupies less space in the vertical direction, is more adapted to the overall layout of a conventional kitchen, and is easier to install.
In one embodiment of the present utility model, referring to fig. 2 and 6, the connection body 100 may further include a solenoid valve 190, the valve body 210 may have a first projection 211 on a second plane, the solenoid valve 190 may have a second projection 191 on the second plane, the auxiliary air passage 130 may have a third projection 137 on the second plane, and the first projection 211 and the second projection 191 may be located at both sides of the third projection 137, respectively. In such an intake assembly, the valve main body 210 may further evade the solenoid valve 190 in the horizontal direction to prevent the control valve 200 from interfering with the solenoid valve 190. In addition, since the first projection 211 of the valve body 210 on the second plane and the second projection 191 of the solenoid valve 190 on the second plane may be located at both sides of the third projection 137 of the auxiliary air passage 130 on the second plane, which is equivalent to that the valve body 210 and the solenoid valve 190 are respectively located at both sides of the auxiliary air passage 130 in the horizontal direction, when the valve body 210 has avoided the solenoid valve 190 by a sufficient distance in the horizontal direction, in such an air intake assembly, the position of the valve body 210 may be slightly shifted upward, and such an air intake assembly may be reduced by at least 5mm in the direction perpendicular to the second plane (which may be understood as the height direction) for the solenoid valve 190 and the control valve 200 in the form of a common self-priming valve conforming to the national standard.
In one embodiment of the present utility model, referring to fig. 2, 3 and 4, an outer ring fire nozzle member 161 may be connected to one end of the outer ring fire passage 120, an outer ring fire nozzle opening 1611 may be provided at an end of the outer ring fire nozzle member 161 adjacent to the connection body 100, and an area of the outer ring fire nozzle opening 1611 passing through may be not greater than an area of the outer ring fire passage 120 passing through. As shown, an outer annular fire nozzle member 161 may be attached to one end of the outer annular fire passage 120, i.e., at the outer annular fire outlet 160. The outer ring fire nozzle 1611 has smaller flow area, the flow velocity of the fuel gas is increased after passing through the outer ring fire nozzle 1611, the fluid pressure is reduced, the fuel gas enters the outer ring fire injection pipe 440 to form negative pressure so as to facilitate the mixing of external air, and then the generated fuel gas-air mixed gas is conveyed to an external outer ring air outlet chamber, so that the fuel gas can be combusted and flame can be generated at the outer ring fire cover 420 connected with the external outer ring air outlet chamber.
In one embodiment of the present utility model, referring to fig. 2, 3 and 4, an inner ring fire nozzle member 151 may be connected to one end of the inner ring fire passage 110, and an inner ring fire nozzle port 1511 may be provided at an end of the inner ring fire nozzle member 151 remote from the connection body 100, and an area of the inner ring fire nozzle port 1511 passing through may be not greater than an area of the inner ring fire passage 110 passing through. The inner annular fire nozzle 1511 has smaller flow area, the flow velocity of the fuel gas is increased after passing through the inner annular fire nozzle 1511, the fluid pressure is reduced, and negative pressure is formed so as to facilitate mixing of external air, thereby generating fuel gas-air mixed gas. The end of the inner ring fire nozzle member 151 remote from the connection body 100 is generally connected to the outer inner ring fire injection pipe 430, and in the inner ring fire injection pipe 430, the gas flowing out of the inner ring fire nozzle port 1511 enters the inner ring fire injection pipe 430 and is mixed with air, so that the gas-air mixed gas is generated and is delivered to the outer inner ring gas outlet chamber, and thus the gas can be combusted and flame can be generated at the inner ring fire cover 410 connected with the outer inner ring gas outlet chamber. The end of the outer ring fire nozzle member 161 remote from the connection body 100 is generally connected to the outer ring fire injection pipe 440, and the outer ring fire injection pipe 440 is similar to the inner ring fire injection pipe 430, except that, since the amount of fuel gas in the outer ring fire channel 120 is generally larger than that in the inner ring fire channel 110, in order to ensure the flame combustion quality in the outer ring fire cover 420, the amount of air to be mixed with the fuel gas is larger, and therefore, the outer ring fire nozzle opening 1611 is disposed on the end of the outer ring fire nozzle member 161 close to the connection body 100, and a mixed flow hole 1612 is also disposed on the end of the outer ring fire nozzle member 161 close to the connection body 100, the fuel gas flowing out from the outer ring fire nozzle opening 1611 first enters the outer ring fire nozzle member 161, and completes the first fuel gas-air mixing through the mixed flow hole 1612, and then the mixed gas enters the outer ring fire injection pipe 440 to complete the second fuel gas-air mixing, so as to ensure that the fuel gas in the outer ring fire channel 120 reaches the outer ring fire cover 420 and participates in combustion after being fully mixed with air.
In one embodiment of the present utility model, referring to fig. 8 and 9, the valve body 210 may be coupled with a connection plate 180, the connection body 100 may include a plate portion 170, a plurality of mounting holes 171 may be provided on the plate portion 170, mounting engagement holes 181 corresponding to the plurality of mounting holes 171 one by one may be provided on the connection plate 180, and a fastener 300 fixedly connects the plate portion 170 and the connection plate 180 through the mounting holes 171 and the corresponding mounting engagement holes 181. As shown, the plate-shaped portion 170 may be provided with 4 mounting holes 171, the connection plate 180 may be provided with 4 mounting holes 181, the mounting holes 181 correspond to the mounting holes 171 one by one, and the 4 fasteners 300 penetrate the mounting holes 171 and the corresponding mounting holes 181 to fixedly connect the plate-shaped portion 170 and the connection plate 180. In other embodiments not shown, the number of mounting holes 171 and mounting mating holes 181 may be arbitrary. Connecting the plate-like portion 170 and the connection plate 180 in this way effectively ensures the overall sealability, and the plate-like portion 170 and the connection plate 180 are not only easy to produce but also very simple to install and connect, that is, by connecting the valve body 210 with the connection body 100 in such a way that the sealability of the whole device is stronger, but also easier to produce and assemble, and high productivity.
The thickness of the plate-like portion 170 may be 1.5mm to 2.5mm, for example, 1.5mm, 1.7mm, 2.0mm, 2.2mm or 2.5mm, and preferably the thickness of the plate-like portion 170 may be 2mm. Such a plate-like portion 170 is itself strong enough to provide an effective seal of the whole device, while the production process of such a plate-like portion 170 is simpler.
The thickness of the connection plate 180 may be 1.5mm to 2.5mm, for example, 1.5mm, 1.8mm, 1.9mm, 2.0mm, 2.3mm or 2.5mm, and preferably, the thickness of the connection plate 180 may be 2mm. . Such a connection plate 180 is itself strong enough to provide an effective seal for the overall device, while the manufacturing process of such a connection plate 180 is simpler.
The connection body 100 may be provided with an auxiliary gas inlet 131 and an auxiliary gas outlet 132, and the auxiliary gas channel 130 may be formed between the auxiliary gas inlet 131 and the auxiliary gas outlet 132. Referring to fig. 2, 3 and 4, an auxiliary gas inlet 131 may be provided on the outer annular fire passage 120, an auxiliary gas outlet 132 may be provided on the inner annular fire passage 110, and such an air intake assembly may be applied to a kitchen range, and may realize inner annular fire rapid-fire frying. Referring to fig. 7, an auxiliary gas inlet 131 and an auxiliary gas outlet 132 may be provided on the inner ring fire channel 110, wherein the auxiliary gas inlet 131 is closer to the gas inlet 140 than the auxiliary gas outlet 132, and such a gas inlet assembly is applied to a kitchen range, and inner ring fire rapid-fire frying may be achieved. In other embodiments, not shown, the auxiliary gas inlet 131 and the auxiliary gas outlet 132 may be provided at any positions on the connection body 100. The auxiliary air channel 130 may be provided with a connection port 133, and the connection port 133 may be a square port, a circular port, or other various communication ports. The auxiliary gas channel 130 may be divided into a first connection section 134 connected to the auxiliary gas inlet 131 and a second connection section 135 connected to the auxiliary gas outlet 132 by the connection port 133, and the fuel gas enters the auxiliary gas channel 130 through the auxiliary gas inlet 131, and the fuel gas in the auxiliary gas channel 130 enters the first connection section 134, then enters the second connection section 135 through the connection port 133, and finally flows out of the auxiliary gas channel 130 from the auxiliary gas outlet 132. The first connection section 134 and the second connection section 135 may have any suitable structure, and the first connection section 134 and the second connection section 135 may have the same structure or different structures. The first connecting section 134 and the second connecting section 135 may be integrally formed, at this time, the connection port 133 is formed naturally at the junction of the first connecting section 134 and the second connecting section 135, or the first connecting section 134 and the second connecting section 135 may be in a split structure and fixedly connected together by threaded connection, welding or other various forms, and the connection port 133 is formed at the junction. The auxiliary gas channel 130 is divided into two parts, a first connecting section 134 and a second connecting section 135, and thus the production, processing and installation of the auxiliary gas channel 130 are easier.
The second connection section 135 may be not higher than the first connection section 134. As shown in fig. 5 and 6, when the connection port 133 is flush with the auxiliary gas outlet 132 and the auxiliary gas outlet 132 is flush with the auxiliary gas inlet 131, the second connection section 135 may have a structure like a "U" shape. The second connection section 135 may be located below the first connection section 134. The control valve 200 may control the auxiliary gas channel 130 to switch between the on state and the off state by controlling the opening or closing of the second connection section 135. In this way, the control valve 200 may be disposed at the lower portion of the whole body of the connection body 100, and the control valve 200 may be practically spaced apart from other portions of the connection body 100, preventing the other portions of the connection body 100 from interfering with the control valve 200, while saving lateral space, and the overall structure of the device may be more compact. And the second connecting section 135 is located below the first connecting section 134, so that the connecting main body 100 can be prevented from being laterally provided with too many pipelines, the space utilization rate of the air inlet assembly is higher, the structure is simpler, and the implementation is easy.
In one embodiment of the present utility model, referring to fig. 5 and 6, the adjustment member 220 may be located at the second connection section 135. The adjusting member 220 is located in the second connecting section 135, and the second connecting section 135 can protect the adjusting member 220, so that the adjusting member 220 is prevented from being interfered by external factors, the movement of the adjusting member 220 between the first position and the second position is more stable, and the stability of the whole device is improved.
The first position may be located directly below the connection port 133. In such an intake assembly, when the regulator 220 blocks the second connecting section 135 such that the auxiliary air passage 130 is in the closed state, the regulator 220 effectively blocks the passage directly below the connection port 133. As shown in fig. 5 and 6, the first position is located directly below the connection port 133, so that the control valve 200 can avoid the electromagnetic valve 190, and interference with the electromagnetic valve 190 is avoided. And when the first position is located right below the connection port 133, the first position is located at a distance from both the auxiliary air inlet 131 and the auxiliary air outlet 132, so that the regulating member 220 located at the first position is prevented from being forcibly retracted into the valve body 210 by the pressure of the air flow. The overall structure of such an air intake assembly is also more compact.
In other embodiments, not shown, the first location may be directly below the auxiliary gas outlet 132. Such a regulating member 220 is located closer to the auxiliary gas outlet 132, and the operation response is quicker when switching the auxiliary gas passage 130 between the on state and the off state.
The flow area of the connection port 133 may be not larger than the flow area of either one of the first connection section 134 and the second connection section 135. On the one hand, the flow area of the connection port 133 is smaller than the flow area of the first connection section 134, that is, the flow area of the connection port 133 is smaller than the flow area of the auxiliary gas inlet 131, so that the gas flow rate of the gas flow at the connection port 133 is larger than the gas flow rate of the gas flow at the auxiliary gas inlet 131, and the gas flow pressure at the connection port 133 is smaller than the gas flow pressure at the auxiliary gas inlet 131, so that the gas can enter the first connection section 134 through the auxiliary gas inlet 131 more easily; on the other hand, the flow area of the connection port 133 is smaller than the flow area of the second connection section 135, that is, the flow area of the connection port 133 is smaller than the flow area of the auxiliary gas outlet 132, so that the gas flow rate of the gas at the connection port 133 is larger than the gas flow rate of the gas at the auxiliary gas outlet 132, and thus, in the process that the gas enters the second connection section 135 from the connection port 133 and reaches the auxiliary gas outlet 132, the gas flow rate is gradually reduced, and finally, when the gas flows out through the auxiliary gas outlet 132, the turbulence generated by the gas flow is less, and the whole gas flow is more stable. The stability of the gas flow direction can be improved by proper design, for example, the flow area of the auxiliary gas outlet 132 can be smaller than the flow area of the auxiliary gas inlet 131 on the basis of the above, so that the stability of the gas flow direction can be further improved, and the gas can be promoted to enter the auxiliary gas channel 130 from the auxiliary gas inlet 131 and flow out of the auxiliary gas channel 130 from the auxiliary gas outlet 132.
The connection port 133 may be circular with a diameter not less than 3mm, the circular connection port 133 being more adapted to a conventional pipe, and the auxiliary gas channel 130 having the circular connection port 133 being more easily installed. The diameter of the connection port 133 may be not smaller than 3mm, so that the influence of the too small diameter of the connection port 133 on the flow effect of the fuel gas in the auxiliary gas channel 130 is avoided.
In one embodiment of the present utility model, referring to fig. 3 and 4, the first connection section 134 may be extended with a third connection section 136 from the connection port 133 along an axial direction of the first connection section 134, an end of the third connection section 136 remote from the first connection section 134 may be formed with an opening 1361 communicating with the outside, and a plug 1362 may be provided at the opening 1361. Such an air intake assembly may be manufactured and installed by machining and adjusting the auxiliary air passage 130 through the opening 1361 without providing the plug 1362. After the auxiliary air channel 130 is disposed, a plug 1362 is disposed at the opening 1361, wherein the plug 1362 may be a screw, a shut-off ball or any other type, and referring specifically to fig. 4, the plug 1362 is in the form of a screw structure in the illustrated embodiment. The provision of the opening 1361 may facilitate the production, processing and installation of the integrated device, and the provision of the plug 1362 may block the opening 1361 to prevent the leakage of fuel gas while enhancing the sealability of the integrated device.
The connection port 133 and the opening 1361 may have a distance L therebetween, L may be 8mm to 20mm, for example L may be 8mm, 9mm, 12mm, 17mm or 20mm. Preferably, the distance L between the connection port 133 and the opening 1361 may be 12mm. Such a distance L may prevent the plug 1362 from restricting the flow of the auxiliary gas channel 130 due to an excessively small distance between the connection port 133 and the opening 1361, thereby ensuring a sufficient flow of the fuel gas in the auxiliary gas channel 130. And such a distance L can avoid excessive space occupation of the overall device due to excessive distance between the connection port 133 and the opening 1361.
