Description

A kind of igniter

Technical field

The utility model belongs to igniting appliance technology, and in particular to one kind is adapted to biomass (wooden) particle furnace use Igniter.

Background technique

It is also and then promoted with the continuous improvement of people's living standards, being enjoyed for life pursuit, therefore people usually can Fireplace is installed at home, heating can be opened and beautifies environment in family.But common fireplace can generate in combustion A large amount of exhaust gas, and it is larger to the difficulty of fuel ignition, although exhaust gas can be discharged outside room by chimney, still can in family There is a little residual, absorbing exhaust gas for a long time will cause healthhazard, then the life of sealed burning and included igniter Substance (wooden) particle furnace gradually popularizes market, and the particle furnace is with advantage that is convenient and efficient and will not impacting to environment in family And liked deeply by the majority of consumers.Biomass (wooden) particle furnace in prior art is led to improve the airtightness of furnace body It directly lights a fire to fuel frequently with the tubulose electrically heated rod for being installed on internal, but is often led due to ambient temperature It is inadequate to send a telegraph hot pin heating temperature, fuel could effectively be lighted by needing to open electrically heated rod for a long time.

In view of the foregoing, it is necessary to design a kind of for biomass (wooden) fuel, fast heating and combustion can be lighted The igniter of material.For this purpose, the applicant has made beneficial design, technical solution described below is in this background Lower generation.

Summary of the invention

The purpose of this utility model is to provide for a kind of igniter, helps to optimize heating rod structure and be able to fuel Pre-heat effect is played to improve heating efficiency and reduce energy consumption.

What the purpose of this utility model was performed by, a kind of igniter, including an electrically heated rod and one are set in Heating tube on the outside of electrically heated rod, the outside of the heating tube are inwardly suppressed at least two grooves along its length, and described is recessed Slot respectively evenly around around heating tube and it is opposite be clamped on the lateral surface of heating tube, the electrically heated rod and A hollow heating extended along its length is respectively formed at position between heating tube and between adjacent two groove Chamber.

In a specific embodiment of the utility model, one end of the electrically heated rod is stretched out heating tube and is constituted One firing tip.

In another specific embodiment of the utility model, the other end of the electrically heated rod stretches out heating tube simultaneously It is connected with a power socket in end, is connected with power supply line on the power socket.

In another specific embodiment of the utility model, an insulating layer is coated on the outside of the heating tube.

In another specific embodiment of the utility model, the insulating layer is asbestos material, in ceramic material One kind.

In the utility model there are one in specific embodiment, the heating chamber section of the heating tube is arc-shaped.

The utility model so that a specific embodiment in, the electrically heated rod using ceramic tube, quartz ampoule, One of stainless steel tube.

In the utility model more and in a specific embodiment, the heating tube is steel pipe.

Again and then in a specific embodiment, pass through between the heating tube and electrically heated rod in the utility model Punch forming and constituted a plurality of groove.

The utility model after adopting the above structure, have the advantages that as use steel pipe made of heating tube with Between electrically heated rod by compacting constitute fluted and heating chamber structure, thus air can be carried out heating and to fuel into Row preheating, can make fuel be rapidly achieved ignition temperature, to effectively improve the heating efficiency of igniter, reduce energy Consumption.

Detailed description of the invention

Fig. 1 is the schematic perspective view of an embodiment of the present invention.

In figure: 1. electrically heated rods, 11. firing tips；2. heating tube, 21. grooves, 22. heating chambers；3. insulating layer；4. power supply Seat, 41. power supply lines.

Specific embodiment

It elaborates by way of examples below, but is not to the utility model technology to the description of embodiment The limitation of scheme, any only formal but not substantive equivalent transformation made according to the utility model design is all It should be regarded as category of the technical solutions of the present invention.

Referring to Fig. 1, the utility model relates to a kind of igniter, including an electrically heated rod 1 and one is set in electric heating The heating tube 2 in 1 outside of stick, the outside of the heating tube 2 is inwardly suppressed at least two grooves 21, the groove along its length 21 are clamped on the lateral surface of heating tube 2 evenly around simultaneously opposite around heating tube 2 respectively, the electrically heated rod Be respectively formed at position between 1 and heating tube 2 and between adjacent two groove 21 one extend along its length it is hollow Heating chamber 22.

Further, the heating rod 1 one end stretch out heating tube 2 and constitute a firing tip 11, heating rod 1 it is another End stretches out heating tube 2 and is connected with a power socket 4 in end, is connected with power supply line 41 on the power socket 4.

Further, the outside of the heating tube 2 is coated with an insulating layer 3.The material of the insulating layer 3 not by appoint What is limited, in the present embodiment preferably one of asbestos, ceramic material.

Further, the cross sectional shape of the heating chamber 22 of the heating tube 2 is unrestricted, excellent in the present embodiment Select arc-shaped structure.

Further, the material of the electrically heated rod 1 is unrestricted, uses ceramic tube, stone in the present embodiment One of Ying Guan, stainless steel tube.
