Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 1 to 3, the present embodiment provides an independent premixed burner 10 for a premixed gas stove, including a base 1 detachably connected to the premixed gas stove and a fire cap 2 disposed in the base 1. The base 1 is provided with an air passage 11 which is through from top to bottom, the air passage 11 is arranged on the central axis of the base 1, and the air passage 11 is used for introducing premixed gas. The fire cap 2 is buckled above the air passage 11, the upper end of the fire cap is provided with a plurality of combustion ports 21, and premixed gas enters the fire cap 2 through the air passage 11 and is suitable for being sprayed out and combusted through the combustion ports 21.

Specifically, the base 1 comprises a connecting portion 12 for connecting with a premix gas burner, a body portion 13 extending upward from the connecting portion 12 to form a first step, and a beam portion 14 extending upward from the body portion 13 to form a second step, wherein a cavity 15 is formed inside the body portion 13, and the lower end of the flame cap 2 is suitable for being installed in the cavity. The beam-shaped part 14 has an annular vertical wall 141, the plurality of combustion ports 21 are arranged on the side wall of the fire cap 2, an annular gap 141 is arranged between the side wall and the annular vertical wall, and the flame sprayed from the combustion ports 21 impacts on the annular vertical wall 141 to form upward flame, so that the effect of correcting the beam shape of the flame is achieved. Meanwhile, the annular gap can prevent redundant air from entering the periphery of the combustion port 21, and the air-fuel ratio of premixed gas sprayed from the combustion port 21 is reduced to achieve the optimal combustion condition, so that the premixed gas is combusted more fully, and the temperature of flame is increased.

How is the burner port 21 not opened directly upward since the ultimate goal is to obtain an upward flame? As is known, the kitchen waste and oil water are easy to fall from the gas stove, if the kitchen waste falls on the burner port 21, the burner port 21 is easily blocked, and the kitchen waste needs to be cleaned frequently in the past, otherwise, the burner port 21 of the gas stove is fewer and fewer, which directly affects the power of the gas stove, and the flame color generated by combustion can turn red due to the attachment, the temperature can be reduced, and the cooking effect is seriously affected. Therefore, the present embodiment provides the combustion port 21 as a flat port and uniformly distributes it on the sidewall of the upper end of the fire cap 2 along the circumferential direction. Thus, even if the vegetable residue falls on the top end of the fire cap 2, the burner port 21 is not blocked.

In addition, a plurality of water drainage holes 16 are arranged at the joint of the body part 13 and the beam-shaped part 14, and the height of the water drainage holes 16 is lower than that of the combustion port 21. When the oil and water fall to the independent premix burner head 10, the oil and water can be discharged through the drain holes 16 so as not to enter the air passage 11 or flood the burner ports 21.

In this embodiment, the fire cap 2 is cylindrical, the cavity 141 in the base 1 is also cylindrical, and the fire cap 2 and the cavity 141 are in clearance fit. Thus, when the fire cap 2 is placed in the cavity 141, the gap between the fire cap and the cavity is small, and the vegetable residue and the oil water can be prevented from entering the air channel 11 through the gap. Meanwhile, the fire cap 2 and the base 1 are of a split structure, so that the fire cap can be conveniently processed and cleaned of sundries.

Preferably, the connecting portion 12 is connected to the premixed gas burner through a screw thread, so that on one hand, the installation and the disassembly are convenient, and on the other hand, the airtightness between the premixed gas burner and the premixed burner 10 can be ensured, and the premixed gas can be prevented from leaking.

Through designing above structure, the premix burner 10 of this embodiment is simple structure not only, and processing is convenient, can prevent moreover that vegetable residue and profit from dropping and causing the jam of air flue 11 or burner port 21, simultaneously, can correct and restraint the shape to flame, makes flame upwards burn.

Referring to fig. 4, the present invention further provides a premix gas burner 100, which includes a burner 110, wherein a first burner 120 and a second burner 130 are disposed in the burner 110, and the second burner 130 can be the independent premix burner described in fig. 1 to 3.

In this embodiment, the first combustion head 120 is connected to a first air source through a first air passage 121, and the second combustion head 130 is connected to a second air source through a second air passage 131. In this way, the first combustion head 120 and the second combustion head 130 may be separately controlled to achieve independent combustion.

For example, the first burner head 120 is configured as a primary burner head to provide a high power flame for high fire cooking, and the second burner head 130 is configured as a secondary burner head to provide a low power flame for low fire cooking. Meanwhile, a side ignition device 140 is disposed beside the first combustion head 120, and the side ignition device 140 is a normally open fire for igniting the first combustion head 120 and/or the second combustion head 130. Therefore, when the cooking with big fire is needed, the main combustion head and the auxiliary combustion head can be opened, and when the cooking with small fire is needed, the main combustion head can be closed and the auxiliary combustion head is reserved, so that the independent control of the small fire and the big fire is realized.

To sum up, the utility model discloses an independent premix combustion head include the base with set up in two parts of flame cap in the base, wherein, the base is provided with the air flue that link up from top to bottom, the flame cap lock in the top of air flue is provided with a plurality of burner ports in the upper end for it passes through to mix the gas in advance the air flue gets into behind the flame cap, via a plurality of burner ports blowout and burning. The independent premixed combustion head of this kind of structure is simple structure not only, and processing is convenient, can be miniaturized independent premixed combustion head moreover, simultaneously, will independently premix combustion head and the detachable connection of premixing gas range, not only can set up a plurality of independent premixed combustion heads in premixing gas range to set for the power of premixing gas range according to the demand of difference, can simplify the structure of premixing gas range moreover, reduce the processing cost of premixing gas range.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
