However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0033] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , an energy-saving gas stove head with more drainage, comprising an upper tube 1 with gas combustion and a lower tube 2 with gas fully mixed, the upper tube 1 is integrally formed at the upper end of the lower tube 2, a main combustion chamber 11 is opened inside the upper tube 1, an independent sinking fire combustion chamber 12 is arranged in the main combustion chamber 11, an ignition needle tube 3 (the ignition needle tube 3 contains an ignition needle, the ignition needle tube 3 is also called a fire protection needle tube) and a fire (long-light) tube 4 are arranged in the independent sinking fire combustion chamber 12, the ignition needle tube 3 passes through the lower tube 2, an air inlet pipe 5 and a main gas joint 6 are arranged on the lower tube 2, and a paired drainage pipe 7 is arranged in the independent sinking fire combustion chamber 12, and the lower end of the paired drainage pipe 7 is located at the lower tube 2, which is conducive to draining the water or oil accumulated in the independent sinking fire combustion chamber 12 into the lower pipe 2, and the paired drainage pipes 7 are symmetrically distributed on the independent sinking fire combustion chamber 12, which will improve the balance, and a straight drainage pipe 8 is provided on the main combustion chamber 11, the straight drainage pipe 8 passes through the lower pipe 2, and an introduction hole 81 is provided on the side wall of the straight drainage pipe 8 close to the lower end surface of the lower pipe 2. This arrangement is not only conducive to the straight drainage pipe 8 to directly discharge the water or oil accumulated on the main combustion chamber 11, but also the introduction hole 81 can discharge the water or oil discharged into the lower pipe 2 by the paired drainage pipes 7 through the introduction hole 81 and then be discharged through the straight drainage pipe 8.

[0034] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the introduction hole 81 faces the side of the air inlet pipe 5, which is not only conducive to drainage and sewage discharge, but also can play a role in air replenishment. When the fire (long-burning) pipe 4 in the independent sinking fire combustion chamber 12 is burning, since there is no drainage and sewage discharge, the air inlet pipe 5 can transport the incoming air upward through the introduction hole 81. This kind of wind is lower than the temperature in the upper pipe 1, which is conducive to a certain cooling effect on the temperature in the upper pipe 1. It is to be noted that the number of straight drainage pipes 8 can be determined according to actual conditions, and in this embodiment, there is only one straight drainage pipe 8, which is conducive to reducing production costs.

[0035] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8As shown, the lower end of the fire starter (long-burning) tube 4 is located in the lower tube 2, and an air intake connector 41 is provided on the fire starter (long-burning) tube 4. The air intake connector 41 is located on the side wall of the lower tube 2, and the external gas is connected through the air intake connector 41, which is conducive to providing gas. At the same time, since the lower end of the fire starter (long-burning) tube 4 is located in the lower tube 2, the lower end of the fire starter (long-burning) tube 4 can be conducive to air intake, which is conducive to mixing the gas at the upper part of the fire starter (long-burning) tube 4, which is more conducive to full combustion. It is worth noting that the lower end face of the fire starter (long-burning) tube 4 is horizontal, and this setting is more reasonable and more conducive to meeting the use requirements. It is also worth noting that the air intake connector 41 is located at the lower part of the lower tube 2. This setting is reasonable, not only convenient for production and manufacturing, but also convenient for users' use requirements.

[0036] When the utility model is ignited, since the air intake joint 41 is connected to the external gas, the air intake pipe 5 is opened due to the cooperation with the fan, and the lower end of the fire starter (long-burning) pipe 4 is located in the lower pipe 2, so that the fan will make the wind enter the upper part of the fire starter pipe 4 from the lower end of the fire starter pipe 4 and mix with the gas. Next, since the ignition needle tube 3 (extinguishing needle) is opened, the mixed gas coming out of the upper end of the fire starter (long-burning) pipe 4 is ignited by the ignition needle tube 3 (extinguishing needle). The independent sinking fire starter combustion chamber 12 is beneficial to reducing the interference of the main combustion chamber 11 with the fire starter. When it is necessary to increase the fire, the main gas joint 6 can be connected, and the gas in the air intake pipe 5 is mixed for the first time in the lower pipe 2 through the fan, and then enters the upper pipe 1 for the second mixing, and finally enters the main combustion chamber 11. After the flame coming out of the independent sinking fire starter combustion chamber 12 is ignited, it is more conducive to full combustion, a large fire can be carried out, and the use can better meet the use needs, and it also makes energy saving and environmental protection, and meets the modern pursuit of development concepts.

[0037] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 3 , Figure 5 and Figure 6As shown, the lower tube 2 includes an outer tube 21 and an inner tube 22 arranged on the lower end of the upper tube 1, both ends of the outer tube 21 and the inner tube 22 are closed, the inner tube 22 is located inside the outer tube 21, and the outer tube 21 and the inner tube 22 are coaxially distributed, the fire tube 4 passes through the inner tube 22 to the outer tube 21, and the paired drainage pipes 7 pass through the inner tube 22 to the outer tube 21, and a wind inlet 221 is provided on one side of the inner tube 22. When drainage and sewage are required, water or oil entering the independent sinking fire combustion chamber 12 is discharged through the paired drainage pipes 7. It is discharged into the outer tube 21, and then enters the straight drain pipe 8 through the introduction hole 81 for discharge. When drainage and sewage are not needed, gas can be introduced from the lower end of the paired drain pipe 7 and the introduction hole 81 respectively, and then the drain pipe 7 exhausts to the independent sinking fire combustion chamber 12, and the introduction hole 81 exhausts to the main combustion chamber 11 through the straight drain pipe 8, which is conducive to better oxygen supply, full mixing, more complete combustion, and also conducive to cooling the main combustion chamber 11 and the independent sinking fire combustion chamber 12, which is more conducive to meeting the use requirements. It should be noted that the air inlet 221 is located on one side of the main gas joint 6, and the main gas joint 6 is provided with an air outlet guide hole 61, through which the gas can be discharged, and then enter the inner tube 22 through the gas outlet guide hole 61, which is conducive to the transportation of the mixed gas.

[0038] like Figure 3 , Figure 5 and Figure 6 As shown, the straight drain pipe 8 is located in the outer pipe 21, and the straight drain pipe 8 passes through the outer pipe 21. Since the straight drain pipe 8 does not pass through the inner pipe 22, this arrangement is beneficial to draining water and sewage in the main combustion chamber 11, and is also beneficial for replenishing wind and air, which is more conducive to meeting usage requirements.

[0039] In the utility model, the air inlet pipe 5 is opened due to cooperation with the fan, wherein the main gas connector 6 is connected to the external main gas. When the two are in an open state, the gas outlet guide hole 61 on the main gas connector 6 can discharge gas, and at the same time, the gas in the air inlet pipe 5 is mixed for the first time in the outer tube 21 through the fan, and then enters the inner tube 22 through the air inlet port 221 for the second mixing, and then enters the upper tube 1 for the third mixing, and finally enters the main combustion chamber 11 for full combustion, so that it can become a high fire for cooking, etc., which is conducive to meeting the user's use needs. This method can be more fully mixed, the combustion flame is bluer, the calorific value is higher, the combustion temperature is as high as 1200 degrees, and gas can be saved by up to 20%, saving gas and time, making the combustion more complete, reducing the emission of pollutants in the flue gas, being more environmentally friendly, and meeting the modern pursuit of development concepts.

[0040] Embodiment 5: It can be described on the basis of embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4, and also includes a cap for covering the independent sinking fire combustion chamber 12. The setting of the cap has been disclosed in the Chinese invention patent application publication number CN117515547A, an energy-saving gas burner head, and will not be described in detail here.

[0041] Embodiment 6: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4 or Embodiment 5, such as Figure 6 and Figure 7 As shown, an air guide port 31 is provided on the ignition needle tube 3 corresponding to the position of the air inlet pipe 5 (a pipe head for the position of the air inlet pipe 5 may also be used). When the utility model ignites, the air inlet pipe 5 is opened due to cooperation with the fan, the ignition needle tube 3 (extinguishing needle) is opened, and the incoming air enters the ignition needle tube 3 through the air guide port 31, which is beneficial for air replenishment and cooling, and is more beneficial for meeting the use requirements.

[0042] The utility model provides paired drainage pipes 7 in the independent sinking fire starter combustion chamber 12, and the lower ends of the paired drainage pipes 7 are located in the lower tube 2. The two drainage pipes 7 used in this embodiment are reasonably arranged and convenient to install. The water or oil in the independent sinking fire starter combustion chamber 12 can be quickly discharged into the outer tube 21, and then discharged through the inlet hole 81 on the straight drainage pipe 8. When there is water or oil in the main combustion chamber 11, it can be directly discharged through the straight drainage pipe 8. In this way, the water or oil in the main combustion chamber 11 in the upper tube 1 and the independent sinking fire starter combustion chamber 12 can be discharged in time, so as to avoid water or oil from entering the fire starter (long-bright) tube 4, which is not conducive to ignition, and is also conducive to avoiding accumulated corrosion, greatly improving the service life, and is also conducive to better ignition and combustion.

[0043] The air intake joint 41 in the utility model is connected to the external gas, and the air intake pipe 5 is opened due to its cooperation with the fan. Since the lower end of the fire starter (long-burning) pipe 4 is located in the lower pipe 2, the fan will allow the wind to enter the upper part of the fire starter pipe 4 from the lower end and mix with the gas. At the same time, since the lower ends of the paired drain pipes 7 are located in the lower pipe 2, the fan will allow the wind to be discharged from the lower end of the drain pipe 7 to the upper end to the independent sinking fire starter combustion chamber 12. The gas touched by the fire starter pipe 4 and the wind (air) blown out of the drain pipe 7 are premixed again, which can make the mixing more complete, the combustion more complete and stable and thorough, so that there is no tail gas, and the carbon monoxide emission will not feel irritating to the eyes. The wind (air) blowing up can play a role in combustion, making it not easy to extinguish; secondly, the fan will cause the wind to be discharged from the lower end of the drain pipe 7 to the upper end to the independent sinking fire starter combustion chamber 12, which is conducive to the replenishment of air to reduce the temperature of the cap, the cap can be cooled quickly, and the durability of the cap is improved.

[0044] In the utility model, a straight drainage pipe 8 is arranged on the main combustion chamber 11, and the straight drainage pipe 8 passes through the lower tube 2, and an inlet hole 81 is arranged on the side wall of the straight drainage pipe 8 close to the lower end surface of the lower tube 2, and the inlet hole 81 faces the side of the air inlet pipe 5, which is not only conducive to drainage and sewage discharge, but also can play a role in air replenishment. When the fire (long-burning) tube 4 in the independent sinking fire combustion chamber 12 is burning, since no drainage and sewage are being discharged, the air inlet pipe 5 can transport the incoming air upward through the inlet hole 81, which plays a role in air replenishment. This kind of wind is lower than the temperature in the upper tube 1, which is beneficial to a certain cooling effect on the temperature in the upper tube 1.

[0045] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0046] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
