Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 4, fig. 1 to 3 respectively show three different perspective views of a flame arrester according to an embodiment of the utility model, and fig. 4 shows a schematic structural view of a combustion assembly according to an embodiment of the utility model. According to an embodiment of the present invention, a fire transfer device includes a fire transfer rod 10. The fire transmission rod 10 is provided with a gas transmission channel 11 which is used for transmitting gas from one end to the other end. The wall of the fire transfer rod 10 is provided with a plurality of first combustion holes 12 communicated with the gas transfer channel 11, and the first combustion holes 12 are sequentially arranged at intervals along the length direction of the fire transfer rod 10. One end of the fire transfer rod 10 is provided with an air inlet communicating with the air transfer passage 11 and is adapted to extend into the interior of the first burner 201 (the left burner 20 as viewed in fig. 4) so that the air transfer passage 11 is adapted to communicate with the gas passage of the first burner 201.

When the flame arrester is assembled in a gas oven to work, gas in the gas channel of the first burner 201 can enter the gas channel 11, and the gas in the gas channel 11 is ejected outwards through the first combustion hole 12. When the gas in the gas channel of the first burner 201 is sprayed outwards for combustion, the flame generated by the first burner 201 contacts the gas sprayed from the adjacent first combustion hole 12, so that the gas sprayed from the adjacent first combustion hole 12 is combusted, and the flame generated at the first combustion hole 12 is sequentially transmitted from one end of the flame transmitting rod 10 to the other end of the flame transmitting rod 10. When the flame of the first combustion hole 12 is transmitted to a position close to the second burner 202, the flame of the first combustion hole 12 can ignite the second burner 202 to perform a fire-transmitting function. For traditional biography fire box, because the gas passes through first burner port 12 blowout, from one of them one end of biography fire pole 10 towards the other end transmission to outside burning at biography fire pole 10, so can reduce in the gas and amass in passing gas passageway 11, guarantee to pass fire efficiency, be favorable to the gas fully to burn, thereby reduced CO's content.

Referring to fig. 4 to 6, fig. 5 is an enlarged structural view of fig. 4 at a, and fig. 6 is an enlarged structural view of fig. 4 at B. Further, the other end of the flame-transmitting rod 10 is provided with an air outlet communicating with the gas-transmitting passage 11, and is adapted to extend into the interior of the second burner 202 (the right burner 20 as shown in fig. 4) so as to communicate the gas-transmitting passage 11 with the gas passage of the second burner 202. Thus, the burners 20 arranged at one end of the fire transfer rod 10 are not only communicated with the fire transfer rod 10, but also communicated with the fire transfer rod 10, that is, the burners 20 arranged at the other end of the fire transfer rod 10 can synchronously provide gas for the fire transfer rod 10, so that enough gas in the gas transfer channel 11 of the fire transfer rod 10 can be ensured to realize that flame is transferred from the first combustion hole 12 at one end of the fire transfer rod 10 to the first combustion hole 12 at the other end of the fire transfer rod 10.

As an alternative, the other end of the fire rod 10 does not need to extend into the second burner 202, and the other end of the fire rod 10 may also be a blocked end, for example, that is, not in communication with the gas channel of the second burner 202.

Referring to fig. 1, 4 and 5, the fire transfer device further includes a limiting frame 30. The limiting frame 30 is disposed at one end of the fire-transmitting rod 10, and the limiting frame 30 is provided with a limiting opening 31 for inserting an end portion (specifically, for example, the mounting plate 214) of the first burner 201. So, the assembly back of biography firearm and first combustor 201, the tip of biography fiery pole 10 stretches into inside the gas passageway of combustor 20, and the tip of combustor 20 then inserts and locates in spacing mouthful 31 of spacing frame 30, can realize like this that the biography fiery is stably located on first combustor 201, avoids passing the firearm and rotate for first combustor 201.

Referring to fig. 1, 4 and 7, fig. 7 is an enlarged schematic view of fig. 4 at C. In one embodiment, the fire transfer device further comprises a limit plate 40 disposed between two ends of the fire transfer rod 10, for example, at a middle portion. The limit plate 40 is provided with a limit hole 41, and the limit hole 41 is used for inserting and installing an end portion (specifically, for example, the mounting plate 214) of the third burner 203. In this way, the end of the third burner 203 (the burner 20 at the middle position shown in fig. 4) can be disposed in the limit hole 41, and the limit hole 41 can limit the end of the third burner 203 to prevent the third burner 203 from moving. Further, when the flame of the first combustion hole 12 of the igniter is transmitted to the end position close to the third burner 203, it can be brought into contact with the gas jetted from the third burner 203, thereby igniting the third burner 203.

Referring to fig. 4 and 5, in one embodiment, a plurality of first combustion holes 12 are formed in a side portion of the wall of the flame transfer rod 10. A plurality of first combustion holes 12 are arranged at regular intervals on the wall of the fire transfer bar 10. In this way, the flame is generated at the side portion of the flame rod 10, so that the gas of the third burner 203 can be easily ignited, even if the flame is easily transmitted to the third burner 203. In addition, the first combustion holes 12 can ensure the flame transfer efficiency when being uniformly arranged at intervals, and are beneficial to full combustion of fuel gas, thereby reducing the content of CO.

When the combustion assembly works, the gas in the gas channel of the first combustor 201 can enter the gas transmission channel 11, and the gas in the gas transmission channel 11 is ejected outwards through the first combustion holes 12. When the gas in the gas channel of the first burner 201 is sprayed outwards for combustion, the flame generated by the first burner 201 contacts the gas sprayed from the adjacent first combustion hole 12, so that the gas sprayed from the adjacent first combustion hole 12 is combusted, and the flame generated at the first combustion hole 12 is sequentially transmitted from one end of the flame transmitting rod 10 to the other end of the flame transmitting rod 10. When the flame of the first combustion hole 12 is transmitted to a position close to the second burner 202, the flame of the first combustion hole 12 can ignite the second burner 202 to perform a fire-transmitting function. For traditional biography fire box, because the gas passes through first burner port 12 blowout, from one of them one end of biography fire pole 10 towards the other end transmission to outside burning at biography fire pole 10, so can reduce in the gas and amass in passing gas passageway 11, guarantee to pass fire efficiency, be favorable to the gas fully to burn, thereby reduced CO's content.
