Description

Technical Field

[0001] This utility model relates to the field of assembled open-hearth furnace head technology, and in particular to an assembled open-hearth furnace head. Background Technology

[0002] In practical applications of open-hearth stoves, whether for outdoor camping, field work heating, indoor cooking, or small-scale industrial heating, there are high requirements for the stove's environmental adaptability, combustion efficiency, and operational stability.

[0003] Traditional open-hearth stove heads are typically designed as a single unit, integrating the stove body and its supporting structure. This design prevents height adjustment or the formation of protective structures to suit different environments. Outdoors, in windy conditions, the lack of effective windbreaks allows strong winds to directly impact the flame, causing it to extinguish or resulting in incomplete combustion. This not only affects heating efficiency but also leads to fuel waste and safety hazards. Conversely, indoor heating requiring intense heat is hampered by a fixed supporting structure that restricts airflow, resulting in incomplete mixing of fuel and air, low combustion efficiency, and an inability to release sufficient heat to meet high-intensity heating demands. To overcome these disadvantages, this invention provides an assembled open-hearth stove head. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an assembled open-hearth furnace head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an assembled open-hearth furnace head, comprising an open-hearth furnace body, a connection port at the top of the open-hearth furnace body, a furnace head body disposed on the connection port, a fixing component disposed on the furnace head body, telescopic chambers fixedly connected to the top of the open-hearth furnace body and on both sides of the connection port, a telescopic rod slidably connected to the telescopic chamber, a support ring fixedly connected to one end of the telescopic rod, several support blocks fixedly connected to the top of the support ring, an adjustment component disposed on the telescopic chamber, a fire-concentrating hood disposed on the furnace head body, a gas supply pipe fixedly connected to the gas inlet of the furnace head body, a fan fixedly connected inside the gas supply pipe, and a filter component disposed at one end of the gas supply pipe.

[0006] Furthermore, the fixing component includes several fixing blocks that are fixedly connected to the furnace head body. A second threaded hole is provided on one side of the fixing block, and several first threaded holes are provided on the top of the open-hearth furnace body. Fixing bolts are threadedly connected to both the first and second threaded holes.

[0007] Furthermore, the adjustment assembly includes a plurality of first pin holes on one side of the telescopic chamber, and a plurality of second pin holes on one side of the telescopic rod, with pins provided on the second pin holes and the first pin holes.

[0008] Furthermore, the fire-gathering hood has a first internal thread inside, and the burner head body has a first external thread, with the fire-gathering hood and the burner head body being threadedly connected.

[0009] Furthermore, the filter assembly includes a filter plate disposed at one end of the air supply pipe, the filter plate being provided with a second external thread, and one end of the air supply pipe being provided with a second internal thread, the filter plate and one end of the air supply pipe being threadedly connected.

[0010] Furthermore, a high-temperature resistant silicone ring is fixedly connected to the burner body on the side of the first external thread.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention utilizes an adjustment assembly consisting of a telescopic chamber, telescopic rod, first pin hole, second pin hole, and pin shaft to flexibly adjust the height of the support ring. Simultaneously, a fan fixed inside the gas pipe actively supplies air, achieving adaptability to different usage environments and optimizing combustion efficiency. When encountering strong winds outdoors, the support ring height can be lowered by adjusting the pin shaft by inserting it into the first and second pin holes at different heights. The support ring and support block form an effective wind barrier, reducing wind interference with the burner flame and ensuring combustion stability. When high-heat cooking is required indoors, the support ring height can be raised, expanding the airflow space around the burner body. Combined with the actively supplied air from the fan, this increases the contact area and mixing efficiency between gas and air. The filter assembly effectively filters the air entering the burner body in outdoor use scenarios, using a filter plate to block dust, sand, weed debris, and other impurities from the outdoor air, preventing these impurities from entering the burner and causing blockage of the gas pipe or affecting gas combustion.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, an assembled open-hearth furnace head is disclosed, comprising a furnace body 1, a connection port 2 at the top of the furnace body 1, a furnace head body 11 mounted on the connection port 2, a fixing component mounted on the furnace head body 11, telescopic chambers 4 fixedly connected to the top of the furnace body 1 and on both sides of the connection port 2, telescopic rods 5 slidably connected to the telescopic chambers 4, a support ring 9 fixedly connected to one end of the telescopic rod 5, several support blocks 10 fixedly connected to the top of the support ring 9, an adjustment component mounted on the telescopic chambers 4, a fire-gathering hood 14 mounted on the furnace head body 11, a gas supply pipe 16 fixedly connected to the gas inlet of the furnace head body 11, a fan 17 fixedly connected inside the gas supply pipe 16, and a filter component mounted at one end of the gas supply pipe 16.

[0021] As shown in the figure, the fixing component includes several fixing blocks 12 that are fixedly connected to the furnace head body 11. A second threaded hole 22 is provided on one side of the fixing block 12, and several first threaded holes 3 are provided on the top of the flat furnace body 1. Fixing bolts 21 are threadedly connected to the first threaded holes 3 and the second threaded holes 22 for fixing the furnace head body 11 to the flat furnace body 1.

[0022] As shown in the figure, the adjustment assembly includes several first pin holes 6 on one side of the telescopic chamber 4 and several second pin holes 7 on one side of the telescopic rod 5. Pins 8 are provided on the second pin holes 7 and the first pin holes 6 for adjusting the height of the support ring 9 and the support block 10.

[0023] As shown in the figure, the flame-gathering cover 14 has a first internal thread 15 inside, and the burner body 11 has a first external thread 13. The flame-gathering cover 14 and the burner body 11 are connected by threads to gather the flame of the burner body 11.

[0024] As shown in the figure, the filter assembly includes a filter plate 19 disposed at one end of the air supply pipe 16. The filter plate 19 is provided with a second external thread 20, and one end of the air supply pipe 16 is provided with a second internal thread 18. The filter plate 19 and one end of the air supply pipe 16 are threadedly connected to each other for filtering the air entering the air supply pipe 16.

[0025] As shown in the figure, a high-temperature resistant silicone ring 23 is fixedly connected to the burner body 11 on one side of the first external thread 13, which is used to seal the connection between the flame-gathering cover 14 and the burner body 11.

[0026] Working principle: First, check the entire device for damage. After inspection, place the burner body 11 at the connection port 2 on the flat furnace body 1. Then, thread the fixing bolts 21 onto the first threaded hole 3 and the second threaded hole 22 to fix the burner body 11 to the connection port 2. Tighten the filter plate 19 to the second internal thread 18 at one end of the gas pipe 16 via the second external thread 20, fixing the filter plate 19 to one end of the gas pipe 16. Then, fix the fire-gathering hood 14 to the burner body 11 by tightening the first external thread 13 and the first internal thread 15. During use, connect the external gas tank. When encountering strong winds outdoors, pull out the pin 8 on the telescopic chamber 4 and the telescopic rod 5, pushing the telescopic rod 5 into the telescopic chamber 4, thereby moving the support ring 9 and the support block 10 down to a suitable height. Then, insert the pin 8 into the corresponding height. The first pin hole 6 and the second pin hole 7 are used to fix the position of the support ring 9. The lowered support ring 9 and the support block 10 are close to the flame shroud 14 to reduce the distance between the flame shroud 14 and the pot on the support block 10, and reduce the direct impact of strong wind on the burner flame. When strong heat is needed indoors, the pin shaft 8 is pulled out and the telescopic rod 5 is pulled out from the telescopic chamber 4, which drives the support ring 9 and the support block 10 to move upward, expanding the air circulation space around the burner body 11. The position of the support ring 9 is then fixed with the pin shaft 8. At this time, the fan 17 continuously and actively delivers air. Combined with the more sufficient air circulation environment brought by the upward movement of the support ring 9, the contact area and mixing efficiency of the gas and air are greatly increased, so that the gas burns more completely and releases more heat to meet the high-intensity heating needs such as high-heat cooking. Before the air enters the gas pipe 16, it is filtered by the filter plate 19.
