Description

Technical Field

[0001] This utility model relates to the field of stove head assembly technology, and in particular to a stove head assembly with adjustable air intake. Background Technology

[0002] Gas burners are commonly used cooking devices in kitchens. Existing gas burners all have a main gas pipe and an air inlet pipe. The main gas pipe carries gas, and the air inlet pipe carries air. The two work together to ensure stable combustion of gas. However, the gas intake volume and the air intake volume need to have a reasonable ratio to achieve stable combustion of gas.

[0003] Among them, utility model application CN202322257835.2 discloses a combustion furnace head, relating to the field of combustion furnace technology, including a furnace head body. A side ring is fixedly connected to the bottom surface of the furnace head body, and a connecting button is fixedly connected to the surface of the side ring. An inner central ring is fixedly connected to the top surface of the furnace head body. An inner air outlet fixedly connected to the left side of the inner central ring facilitates the outward flow of internal contaminants and aids combustion. An outer air outlet fixedly connected to the surface of the outer side ring facilitates combustion and the outward discharge of water stains and fallen debris, improving hygiene. A bottom slope fixedly connected to the bottom of the outer air outlet further facilitates the outward discharge of contaminants and wastewater. A drainage groove fixedly connected to the inner side of the outer side ring and located at the bottom of the furnace head body provides secondary internal contaminant drainage. A drop hole fixedly connected to the surface of the drainage groove and located at the bottom of the furnace head body facilitates the outward discharge of internal contaminants.

[0004] Existing gas burners directly input air into low-pressure gas fuel pipelines at corresponding pressures for air and gas fuel premixing. The air intake is not easy to adjust, which makes the flame easy to go out and affects the efficiency of food preparation in the kitchen. Utility Model Content

[0005] The purpose of this invention is to provide a burner assembly with adjustable air intake to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An adjustable air intake burner assembly includes a burner structure and an air valve structure. The burner structure includes a burner body and a main air inlet and a ignition air inlet formed on the burner body. A bottom air inlet is formed at the bottom of the burner body.

[0008] The air valve structure includes an air duct, with a main air inlet at one end and an air valve outlet at the other end that communicates with the bottom air inlet; an air guide cavity is formed inside the air duct, and a first air outlet is formed in the air guide cavity, which is connected to the ignition air inlet; a first air guide plate is provided in the air guide cavity to guide a portion of the air force to the first air outlet; and an air valve plate that can swing longitudinally to adjust the amount of air passing through is provided in the air guide cavity.

[0009] Furthermore, the burner structure also includes a gas valve, which is equipped with a main gas port, a first gas outlet and a second gas outlet. The first gas outlet is connected to a first gas inlet pipe, and the second gas outlet is connected to a second gas inlet pipe. The first gas inlet pipe is connected to the main gas inlet, and the second gas inlet pipe is connected to the ignition gas inlet.

[0010] Furthermore: the second air intake pipe is connected to a T-junction at its end, one end of which is connected to the ignition air intake, and the other end of which is connected to the first air outlet.

[0011] Furthermore: The first air outlet is equipped with a first regulating valve for adjusting the air volume.

[0012] Furthermore: the air guide cavity is equipped with a main adjusting component for adjusting the swing angle of the air valve plate. The main adjusting component includes a main rotating shaft that is transversely inserted into the air guide cavity. The air valve plate is connected to the main rotating shaft, and one end of the main rotating shaft extends outward.

[0013] Furthermore, the air guide cavity is also equipped with a second air guide plate, which has an air guide opening. The air guide opening is equipped with an adjustment plate, which can rotate to adjust the size of the air guide opening.

[0014] Furthermore, the second air guide plate is also provided with a fine-tuning hole for airflow, and the fine-tuning hole is equipped with a fine-tuning structure to control the amount of airflow passing through the fine-tuning hole.

[0015] Furthermore, the fine-tuning structure includes a fine-tuning rod arranged along the axial direction of the fine-tuning hole and capable of axial movement, with a baffle installed at the end of the fine-tuning rod to block the fine-tuning hole.

[0016] Furthermore: the main air inlet of the air duct is connected to the first air guide pipe, and the first air guide pipe is connected to the fan.

[0017] Furthermore: the air duct has an L-shaped structure, and a second air guide pipe is installed between the bottom air inlet and the air outlet of the air valve at the bottom of the air duct.

[0018] The beneficial effects of this utility model are as follows: The burner structure, through the cooperation of the main air inlet and the ignition air inlet, enables the adjustment of the gas flame intensity. The ignition air inlet ensures that the burner structure will not go out. The cooperation between the air duct and the bottom air inlet of the burner structure increases the flame intensity. In addition, the air guide valve plate inside the air duct can be swung to adjust the air volume of the bottom air inlet and thus the flame intensity. A portion of the air volume is mixed with oxygen through the first air inlet and the ignition air inlet. When the main air inlet is turned off, it ensures that the ignition flame in the ignition air inlet will not go out, thus enabling arbitrary adjustment of the burner's flame intensity.

[0035] The present invention will now be described in detail with reference to the accompanying drawings.

[0036] like Figure 1-4 As shown, an adjustable air intake burner assembly includes a burner structure 1 and an air valve structure 2. The burner structure 1 includes a burner body 11 and a main air inlet 12 and a ignition air inlet 13 formed on the burner body 11. A bottom air inlet 14 is formed at the bottom of the burner body 11.

[0037] The air valve structure 2 includes an air duct 21. One end of the air duct 21 is provided with a main air inlet 23. The main air inlet 23 of the air duct 21 is connected to a first air guide pipe 24. The first air guide pipe 24 is connected to a fan 25. The air volume generated by the fan 25 is introduced into the air duct 21 through the first air guide pipe 24.

[0038] The other end of the air duct 21 is provided with an air valve outlet 26 that is connected to the bottom air inlet 14; the air duct 21 has an L-shaped structure, and a second air guide pipe 27 is provided between the bottom air inlet 14 at the bottom of the air duct 21 and the air valve outlet 26 of the air duct 21. The air duct 21 can be connected to the furnace head structure 1 through the air valve outlet 26 and the second air guide pipe 27.

[0039] The air duct 21 has an air guide cavity 22 formed inside, and the air guide cavity 22 has a first air outlet 3 formed inside. The first air outlet 3 is connected to the ignition air inlet 13. The air guide cavity 22 is provided with a first air guide plate 31 that directs a portion of the air force to the first air outlet 3. The air guide cavity 22 is provided with a wind valve plate 33 that can swing longitudinally and adjust the amount of air passing through.

[0040] The burner structure 1, through the cooperation of the main air inlet 12 and the ignition inlet 13, enables the adjustment of the gas flame intensity. The ignition inlet 13 ensures that the burner structure 1 will not go out. The flame intensity of the burner structure 1 is increased by cooperating with the bottom air inlet 14 of the air duct 21. In addition, the air guide valve plate 33 inside the swingable air duct 21 allows the air volume of the bottom air inlet to be adjusted, and the flame intensity can be adjusted. A portion of the air volume is mixed with oxygen through the first air inlet and the ignition inlet 13. When the main air inlet 12 is turned off, it ensures that the flame in the ignition inlet 13 will not go out, thus enabling arbitrary adjustment of the burner's flame intensity.

[0041] Specifically, the burner structure 1 also includes a gas valve 15, which is provided with a main gas port 16, a first gas outlet 17 and a second gas outlet 18. The first gas outlet 17 is connected to a first air inlet pipe 191 and the second gas outlet 18 is connected to a second air inlet pipe 192. The first air inlet pipe 191 is connected to the main air inlet 12 and the second air inlet pipe 192 is connected to the ignition inlet 13. Gas enters through the main gas port 16 of the gas valve 15 and is then split through the first gas outlet 17 and the second gas outlet 18. Part of the gas is introduced into the main air inlet 12 through the first air inlet pipe 191 and part of the gas is introduced into the ignition inlet 13 through the second air inlet pipe 192.

[0042] Preferably, the second air intake pipe 192 is connected to a three-way connector 19 at its end. One end of the three-way connector 19 is connected to the ignition inlet 13, and the other end of the three-way connector 19 is connected to the first air outlet 3. With the cooperation of the three-way connector 19, air and gas are mixed at the three-way connector 19 and then introduced into the ignition inlet 13, increasing the stability of the flame, reducing the probability of the ignition inlet 13 going out, and ensuring the stability of combustion.

[0043] Preferably, the first air outlet 3 is equipped with a first regulating valve 32 for adjusting the air volume. The air volume entering the three-way interface 19 can be adjusted by the first regulating valve 32 to prevent the excessive air volume from blowing out the flame of the ignition inlet 13, thereby further stabilizing the flame combustion stability of the ignition inlet 13.

[0044] The air guide cavity 22 is provided with a main adjusting component 34 for adjusting the swing angle of the damper plate 33. The main adjusting component 34 includes a main rotating shaft 35 that is transversely inserted into the air guide cavity 22. The damper plate 33 is connected to the main rotating shaft 35, and one end of the main rotating shaft 35 extends outward. By rotating the damper plate 33, the passage area of ​​the air guide cavity 22 can be adjusted, that is, the air volume will change, thereby adjusting the air volume. Specifically, during adjustment, the main rotating shaft 35 is turned, and the damper plate 33 installed on the main rotating shaft 35 swings longitudinally accordingly to adjust the air volume.

[0045] Since the air valve plate 33 of the air guide cavity 22 has relatively low accuracy in adjusting the air volume and cannot meet the requirements for precise air volume control, the air guide cavity 22 is also provided with a second air guide plate 36. The second air guide plate 36 has an air guide port 37, and an adjustment plate 38 is installed on the air guide port 37. The adjustment plate 38 can rotate to adjust the size of the air guide port 37. The second air guide plate 36 also has a fine adjustment hole 39 for air to pass through. The fine adjustment hole 39 is equipped with a fine adjustment structure to control the amount of air passing through the fine adjustment hole 39. The fine adjustment structure includes a fine adjustment rod 40 arranged axially along the fine adjustment hole 39 and capable of axial movement. A baffle 41 that can block the fine adjustment hole 39 is installed at the end of the fine adjustment rod 40. By rotating the fine-tuning rod 40, the fine-tuning rod 40 can move axially along the fine-tuning hole 39. The baffle 41 installed at the end of the fine-tuning rod 40 can move closer to or further away from the fine-tuning hole 39, so that the air volume passing through the fine-tuning hole 39 can be adjusted. Since the aperture of the fine-tuning hole 39 is small, the air volume can be finely adjusted, and the required air volume can be adjusted to match the firepower of the burner structure 1.

[0046] Preferably, the air guide cavity 22 is provided with a threaded sleeve 42 that is threadedly engaged with the fine-tuning rod 40. When the fine-tuning rod 40 is rotated, the fine-tuning rod 40 and the threaded sleeve 42 are threadedly engaged, and the fine-tuning rod 40 achieves axial sliding engagement with the fine-tuning hole 39 to finely adjust the air intake volume.

[0047] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0048] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
