Abstract

The utility model discloses a premix burner, which comprises a combustion head, a mixing input pipe and an air inlet device, wherein the air inlet device is arranged at the position right below the combustion head, and the air inlet device is connected with the bottom of the combustion head through the mixing input pipe; the utility model has the advantages of reasonable design, it is practical convenient, can mix gas and air in advance for the gas is changed in the ignition, also can be convenient for the gas more abundant burning simultaneously.

Description

Premixing burner

Technical Field

The utility model belongs to the technical field of the kitchen utensils and appliances and specifically relates to a premix burner is related to.

Background

Traditional combustor is when carrying out gas ignition burning, all directly igniteing through gas input pipeline and through some firearm through direct with combustor lug connection usually, because the gas ignition in-process needs to contact with the air and mixes, just can realize the ignition, consequently traditional combustor, its gas is usually just mixed with the air at a fire hole department, consequently comparatively difficult at the initial in-process of igniteing, need a lot of ignition just can succeed, and the gas is just mixed with the air at a fire hole, just also make the burning of gas not abundant enough, cause the gas extravagant easily.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem of coming, provide a premix combustor for this reason, including combustion head, mixed input tube and hot blast blowpipe apparatus, hot blast blowpipe apparatus sets up position department under the combustion head, hot blast blowpipe apparatus is connected with the combustion head bottom through mixing the input tube, be provided with a plurality of holes of putting a fire on the up end of combustion head, the central point of combustion head puts the department and is provided with the inner chamber, it has a plurality of holes of putting a fire to also set up on the inner chamber, hot blast blowpipe apparatus's bottom is provided with the fresh air inlet, be provided with the motor in the hot blast blowpipe apparatus, the upper end of motor is provided with the fan, the fan drives through the motor, mixed input tube sets to the screw thread shape structure, the diameter of mixed input tube diminishes gradually from bottom to top, the connection of one side position department of mixed input tube is provided with the intake pipe.

Preferably, an igniter is disposed at one side of the combustion head.

The utility model has the advantages that: the utility model has the advantages of reasonable design, it is practical convenient, can mix gas and air in advance for the gas is changed in the ignition, also can be convenient for the gas more abundant burning simultaneously.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic view of the overall structure of the present invention;

in the figure: 1. an air intake device; 2. a burner head; 3. a fire outlet; 4. an igniter; 5. an air inlet pipe; 6. a mixing input pipe; 7. a fan; 8. an air inlet hole; 9. a motor; 10. an inner cavity.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

A premix burner as shown in fig. 1, comprising a burner head 2, a mixing inlet pipe 6 and an air intake device 1, the air intake device 1 is arranged at the position right below the combustion head 2, the air intake device 1 is connected with the bottom of the combustion head 2 through a mixing input pipe 6, a plurality of fire outlets 3 are arranged on the upper end surface of the combustion head 2, an inner cavity 10 is arranged at the central position of the combustion head 2, the inner cavity 10 is also provided with a plurality of fire outlets 3, the bottom of the air inlet device 1 is provided with an air inlet hole 8, a motor 9 is arranged in the air intake device 1, a fan 7 is arranged at the upper end of the motor 9, the fan 7 is driven by the motor 9, the mixing input pipe 6 is arranged into a thread structure, the diameter of the mixing input pipe 6 is gradually reduced from bottom to top, and an air inlet pipe 5 is connected and arranged at one side position of the mixing input pipe 6.

An igniter 4 is arranged on one side of the combustion head 2.

In the using process, the motor 9 operates to drive the fan 7 to rotate, so that air entering through the air inlet hole 8 is conveyed into the mixing input pipe 6 through the rotation of the fan 7, meanwhile, the air inlet pipe 5 inputs fuel gas into the mixing input pipe 6, so that the air and the fuel gas are premixed in the mixing input pipe 6, then the premixed fuel gas is input into the combustion head from the mixing input pipe 6, the ignition is carried out through the igniter 4, and the mixed fuel gas is discharged from the fire outlet hole 3.

The mixing inlet pipe 6 is provided with a thread structure, which enables the air and the gas in the mixing inlet pipe 6 to be conveyed in a rotating manner, and simultaneously enables the air and the gas to be better mixed in the mixing inlet pipe 6.

The diameter of the mixing input pipe 6 is gradually reduced from bottom to top, so that the conveying of air and fuel gas can be further accelerated.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
