Description

Technical Field

[0001] This utility model relates to the field of stove accessories technology, specifically to a clean fuel-efficient stove cover. Background Technology

[0002] As a core piece of cooking equipment, the stove's combustion efficiency, heat utilization efficiency, and safety directly affect the cooking experience and energy consumption. Clean fuels (such as biodiesel and alcohol-based fuels) are increasingly widely used in residential and commercial stoves due to their environmental and renewable advantages. However, fuel combustion has higher requirements for oxygen supply and airflow stability than traditional gas combustion, and existing stove hood structures are difficult to adapt to these requirements.

[0003] In practical use, existing technologies present a contradiction between wind protection and oxygen supply. The enclosed structure leads to insufficient oxygen supply, while heat is lost in a diffuse manner, resulting in low thermal energy utilization. Utility Model Content

[0004] The purpose of this invention is to provide a clean fuel-fired energy-concentrating furnace cover to solve the problems of conflict between wind protection and oxygen supply, as well as low thermal energy utilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clean fuel-fired energy-concentrating furnace hood, comprising:

[0006] The stove has a stove frame fixedly connected to its top, a support ring movably overlapped on the top of the stove frame, a heat-collecting ring fixedly connected to the surface of the support ring, and hot air holes opened on the surface of the support ring.

[0007] The surface of the furnace frame is movably connected to an inner ring, the surface of the inner ring is rotatably connected to an outer ring, and a first adjusting ring and a second adjusting ring are rotatably connected between the inner ring and the outer ring, and the first adjusting ring and the second adjusting ring are tightly fitted together.

[0008] The inner ring, outer ring, first adjusting ring, and second adjusting ring are each provided with an air inlet for air circulation.

[0009] Preferably, the top of the support ring is a horizontal structure, and the top of the heat-collecting ring is an flared structure, with the hot air holes arranged vertically.

[0010] Preferably, both the inner and outer rings have L-shaped cross-sections, and the number of heat-gathering rings is four, which are arranged in a ring on the top of the stove so that the four heat-gathering rings can position the inner ring.

[0011] Preferably, guide rings are fixedly connected to the bottom of the inner wall of the inner ring and the top of the inner wall of the outer ring, and the first adjusting ring and the second adjusting ring are rotatably connected to the inner wall of the guide ring, so that the two guide rings guide the rotation of the first adjusting ring and the second adjusting ring.

[0012] Preferably, the outer ring is located on the inner wall of the first adjusting ring, and the first adjusting ring is located on the inner wall of the second adjusting ring. The air inlets in the middle of the outer ring and the first adjusting ring are the same size, and the air inlets in the middle of the first adjusting ring and the second adjusting ring are the same size. The air inlets in the middle of the first adjusting ring and the second adjusting ring are larger than the air inlets in the middle of the outer ring and the first adjusting ring.

[0013] Preferably, a handle is rotatably connected to the middle of the second adjusting ring, and a drive frame is fixedly connected to one end of the handle corresponding to the position of the first adjusting ring. The drive frame has a C-shaped structure, and a drive groove is opened in the middle of the first adjusting ring corresponding to the position of the drive frame. The drive frame is movably connected to the inner wall of the drive groove, so that when the handle drives the drive frame to rotate, the drive frame cooperates with the drive groove to drive the first adjusting ring to rotate on the inner wall of the second adjusting ring.

[0014] Preferably, the outer ring has a movable groove in the middle corresponding to the handle position. The handle is movably connected to the inner wall of the movable groove. Guide seats are fixedly connected to both ends of the surface of the handle corresponding to the movable groove position. The two guide seats are located on the inner wall and the surface of the outer ring, respectively. The guide seats have an arc-shaped structure, and the arc center of the guide seat is located on the same numerical axis as the center of the outer ring. The height of the guide seat is greater than the height of the movable groove, so that the two guide seats cooperate with the movable groove to guide the movement of the handle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses the alternating arrangement of the first and second adjusting rings to change the amount of air passing through the air inlet, thereby reducing the wind speed. Finally, the slowed wind will supplement the top of the stove through the air inlet in the middle of the outer ring. Throughout the process, the wind will not affect the flame burning at the top of the stove, nor will it cause insufficient air supply, thus achieving the goal of windproofing and oxygen supply at the same time.

[0017] 2. This utility model also allows the drive frame to rotate when the handle is turned. When the drive frame rotates without the second adjusting ring rotating, it causes the first adjusting ring to rotate on the inner wall of the second adjusting ring in conjunction with the drive groove. This adjusts the staggered state of the air inlet holes in the middle of the first and second adjusting rings, thereby adjusting the air intake volume. When the handle moves along the inner wall of the movable groove, it simultaneously drives the first and second adjusting rings to rotate on the inner walls of the inner and outer rings. This adjusts the staggered state of the first and second adjusting rings as a whole with the air inlet holes in the middle of the inner and outer rings, reducing the wind speed and drawing the wind into the top of the stove, thus improving combustion efficiency when there is wind.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a clean fuel-fired energy-concentrating furnace hood, comprising:

[0028] The stove 1 has a stove frame 2 fixedly installed on its top. A support ring 3 is movably connected to the top of the stove frame 2. A heat-gathering ring 4 is fixedly installed on the surface of the support ring 3. Hot air holes 16 are opened on the surface of the support ring 3. The top of the support ring 3 is a horizontal structure, and the top of the heat-gathering ring 4 is an flared structure. The hot air holes 16 are set vertically.

[0029] The surface of the furnace frame 2 is movably connected to an inner ring 5, the surface of the inner ring 5 is rotatably connected to an outer ring 6, and a first adjusting ring 7 and a second adjusting ring 8 are rotatably connected between the inner ring 5 and the outer ring 6, and the first adjusting ring 7 and the second adjusting ring 8 are tightly fitted together.

[0030] The inner ring 5, outer ring 6, first adjusting ring 7 and second adjusting ring 8 are each provided with an air inlet 9 for air circulation. The cross-section of the inner ring 5 and outer ring 6 are both L-shaped. There are four heat-gathering rings 4, which are arranged in a ring on the top of the stove 1 so that the four heat-gathering rings 4 can position the inner ring 5. The outer ring 6 is located on the inner wall of the first adjusting ring 7, and the first adjusting ring 7 is located on the inner wall of the second adjusting ring 8. The air inlets 9 in the middle of the outer ring 6 and the first adjusting ring 7 are the same size, and the air inlets 9 in the middle of the first adjusting ring 7 and the second adjusting ring 8 are the same size. The air inlets 9 in the middle of the first adjusting ring 7 and the second adjusting ring 8 are larger than the air inlets 9 in the middle of the outer ring 6 and the first adjusting ring 7.

[0031] In use, the above structure, by rotating the inner ring 5, outer ring 6, first adjusting ring 7, and second adjusting ring 8, and adjusting the corresponding positions of the air inlets 9 in the middle of the inner ring 5, outer ring 6, first adjusting ring 7, and second adjusting ring 8, achieves the function of blocking and buffering wind. That is, when the outside wind blows towards the first adjusting ring 7 and second adjusting ring 8 through the air inlet 9 in the outer ring 6, the staggered arrangement of the first adjusting ring 7 and the second adjusting ring 8 changes the amount of air passing through the air inlet 9, thereby reducing the wind speed. Finally, the slowed wind will supplement the top of the stove 1 through the air inlet 9 in the middle of the outer ring 6 between the first adjusting ring 7 and the outer ring 6. Throughout the process, the wind will not affect the flame burning at the top of the stove 1, nor will it cause insufficient air supply, thus achieving the purpose of wind prevention and oxygen supply simultaneously.

[0032] Guide rings 10 are fixedly installed on the bottom of the inner wall of the inner ring 5 and the top of the inner wall of the outer ring 6. The first adjusting ring 7 and the second adjusting ring 8 are rotatably connected to the inner wall of the guide rings 10 so that the two guide rings 10 guide the rotation of the first adjusting ring 7 and the second adjusting ring 8. A handle 11 is rotatably connected to the middle of the second adjusting ring 8. A drive frame 12 is fixedly installed at one end of the handle 11 corresponding to the position of the first adjusting ring 7. The drive frame 12 has a C-shaped structure. A drive groove 13 is opened in the middle of the first adjusting ring 7 corresponding to the position of the drive frame 12, and the drive frame 12 is movably connected to the inner wall of the drive groove 13 so that the handle 11 drives the drive frame 12. When rotating, the drive frame 12, in conjunction with the drive groove 13, drives the first adjusting ring 7 to rotate on the inner wall of the second adjusting ring 8. The outer ring 6 has a movable groove 14 in the middle corresponding to the position of the handle 11. The handle 11 is movably connected to the inner wall of the movable groove 14. Guide seats 15 are fixedly installed at both ends of the surface of the handle 11 corresponding to the position of the movable groove 14. The two guide seats 15 are located on the inner wall and the surface of the outer ring 6, respectively. The guide seats 15 have an arc-shaped structure, and the arc center of the guide seat 15 and the center of the outer ring 6 are located on the same numerical axis. The height of the guide seat 15 is greater than the height of the movable groove 14, so that the two guide seats 15 cooperate with the movable groove 14 to guide the movement of the handle 11.

[0033] In use, the above structure rotates the handle 11, causing the drive frame 12 to rotate. When the drive frame 12 rotates while the second adjusting ring 8 is not rotating, the drive frame 12, in conjunction with the drive groove 13, causes the first adjusting ring 7 to rotate on the inner wall of the second adjusting ring 8. This adjusts the staggered state of the air inlet holes 9 in the middle of the first adjusting ring 7 and the second adjusting ring 8, thereby adjusting the air intake volume. When the handle 11 moves along the inner wall of the movable groove 14, it simultaneously causes the first adjusting ring 7 and the second adjusting ring 8 to rotate on the inner walls of the inner ring 5 and the outer ring 6, thereby adjusting the staggered state of the first adjusting ring 7 and the second adjusting ring 8 as a whole with the air inlet holes 9 in the middle of the inner ring 5 and the outer ring 6.

[0034] Working principle: When in use, this utility model ensures that the air inlet holes 9 in the middle of the inner ring 5, outer ring 6, first adjusting ring 7, and second adjusting ring 8 are aligned when the stove 1 is working. At this time, outside air can be directly drawn into the middle of the stove 1 through pressure to participate in the combustion of fuel. The hot air generated by the high temperature in the middle of the stove 1 will flow upward and flow upward from the vertical hot air hole 16 in the middle of the support ring 3. Finally, it will be guided by the heat-gathering ring 4 and surround the surface of the heated container, which can play a role in uniformly keeping the top of the heated container warm, so that the temperature difference between the bottom and the top of the heated container is not large. At the same time, by setting the heat-gathering ring 4, the hot air can also be prevented from directly hitting the user's face, avoiding discomfort to the user.

[0035] When used in windy conditions, rotating the inner ring 5, outer ring 6, first adjusting ring 7, and second adjusting ring 8 adjusts the corresponding positions of the air inlets 9 in the middle of the inner ring 5, outer ring 6, first adjusting ring 7, and second adjusting ring 8, thus achieving the function of blocking and buffering the wind. That is, when the outside wind blows through the air inlet 9 in the outer ring 6 towards the first adjusting ring 7 and second adjusting ring 8, the staggered arrangement of the first adjusting ring 7 and second adjusting ring 8 changes the amount of air passing through the air inlet 9, thereby reducing the wind speed. Finally, the slowed wind will supplement the top of the stove 1 through the air inlet 9 in the middle of the outer ring 6 between the first adjusting ring 7 and the outer ring 6. Throughout the process, the wind will not affect the flame burning at the top of the stove 1, nor will it cause insufficient air supply, thus achieving the purpose of wind prevention and oxygen supply at the same time.

[0036] The air inlet holes 9 in the middle of the inner ring 5, outer ring 6, first adjusting ring 7 and second adjusting ring 8 can be freely adjusted to adjust their degree of overlap as needed. The relative rotation of the first adjusting ring 7 and second adjusting ring 8 is mainly used to adjust the amount of air intake. The overall movement of the first adjusting ring 7 and second adjusting ring 8 is mainly used to achieve the overlap of the air inlet holes 9 in the middle of the inner ring 5, outer ring 6 and first adjusting ring 7 and second adjusting ring 8, so as to reduce the wind speed and avoid the wind affecting the flame burning at the top of the stove 1.

[0037] By rotating the handle 11, the drive frame 12 is driven to rotate. When the drive frame 12 rotates without the second adjusting ring 8 rotating, the drive frame 12, in conjunction with the drive groove 13, drives the first adjusting ring 7 to rotate on the inner wall of the second adjusting ring 8. This adjusts the staggered state of the air inlet holes 9 in the middle of the first adjusting ring 7 and the second adjusting ring 8, thereby adjusting the air intake volume. When the handle 11 moves along the inner wall of the movable groove 14, it simultaneously drives the first adjusting ring 7 and the second adjusting ring 8 to rotate on the inner walls of the inner ring 5 and the outer ring 6. This adjusts the staggered state of the first adjusting ring 7 and the second adjusting ring 8 with the air inlet holes 9 in the middle of the inner ring 5 and the outer ring 6, thereby reducing the wind speed and drawing the wind into the top of the stove 1, thus improving combustion efficiency when there is wind.
