CN2280275Y - Apparatus for producing color flame - Google Patents

Abstract

The utility model relates to an apparatus for producing color flame, which is characterized in that a color former solution feed mechanism is arranged under a fuel gas mixing chamber which is communicated with the negative pressure zone of a fuel gas nozzle through a capillary pipette of the color former solution. The utility model can generate various colorful color flames seen clearly and obviously under the condition of daylight as the combustion of the fuel gas. The utility model is suitable for making an athlete hand-held color flame torch or a fixed color flame torch for a large sport meeting place or a birthday candle type miniature color torch.

Description

A kind of device that produces colored flames

The utility model belongs to the daily necessities category that sets off red-letter day or celebrating atmosphere by contrast, relates in particular to a kind of device that can produce colored flames with fuel gas buring.

Can be used to make the series products of athletic meeting with colored flames torch or gas type new type colorful flame birthday torch.

In the prior art, CN91203336.3 and CN91101567 provide a kind of gas burning torch, and it is made up of burner, pressure-reducing valve, igniter and housing, and wherein igniter is flame-out automatic resume combustion pulse igniter.Fuel cartridge places bottom in the housing during use, tightens the housing bottom, and fuel cartridge is up, and the tank deck check valve is backed down, and fuel gas flows into burner through decompression venting valve, igniter action simultaneously, torch burning; Otherwise combustion gas is closed, and igniter extinguishes.

The deficiency of prior art is that the flame tone is single, is that orchid is slightly yellow substantially, seems not eye-catching daytime.

The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, imagination is improved the structure of gas burning torch, utilize the power at gas nozzle place, when being entrained in burning, the capillary syring suction produces the metallic salt solution of flame reaction, make its mixed combustion, produce under the condition on daytime clear eye-catching red, green, purplish red, fat is red, multiple gorgeous colorful colored flames such as dark red.

The inventive concept of this device is implemented by following technical solution:

Utilize the principle of prior art, this device comprises the fuel gas supply part of bottom, the combustion chamber on top, middle mixing chamber makes upper and lower connection by controlling organization, there are automatic igniting and flame-out resume combustion mechanism in combustion chamber place, it is characterized in that the toner solutions feed mechanism is arranged below mixing chamber, communicate with the gas nozzle negative pressuren zone via the capillary syring that promotes toner solutions.

Above-mentioned toner solutions feed mechanism comprises solution bunker 9, the lower end is immersed under bunker 9 liquid levels, capillary syring 17 and the lower end of upper end open in gas nozzle 15 negative pressuren zones of atomizing mixing chamber 12 is communicated with bunker 9, and upper end open is in the return duct 16 of atomizing mixing chamber 12 bottoms.

Below in conjunction with drawings and Examples this device is further elaborated:

Fig. 1 is the color fireworks torch of embodiment hand-held of this a device structural representation;

Fig. 2 is annular fuel gas nozzle and a plurality of toner solutions combining structure schematic diagram of the huge colorful fixed torch of another embodiment park;

Fig. 3 is the little Torch structure schematic diagram of the color flame of miniature " cured candle of birthday " formula.

Among the figure: the 1st, handle, the 2nd, torch body, the 3rd, flare tip, the 4th, fuel cartridge, the commercially available lighter that fills gets final product with little fuel cartridge, the 5th, the fuel cartridge positioning supporting frame, the 6th, top-pressure mechanism, by screw handle end " ", can make position fuel cartridge thereon up easily, otherwise then effect is opposite, the 7th, be fixed on the control assembly of the plaing of torch body inwall " switch " effect, middle circular hole and fuel cartridge 4 top air outlet valve profiles are coincide and are mated, the 8th, ignition mechanism, piezoelectric ceramics igniting pin or pulsed igniter on the conventional gas-cooker all can, the key takeaway fire is convenient, flame-out automatic resume combustion, the 9th, the toner solutions bunker, preserve lithium as required, potassium, copper, sodium, calcium etc. can produce the salting liquid of flame reaction, concentration gets final product in the PPM level, the 10th, the liquid level indication of above-mentioned solution bunker, the 11st, above-mentioned solution hand-hole and double as ventilation balance pipe, the 12nd, the atomizing mixing chamber, can make the gas-liquid two-phase mixing that fully atomizes, big droplets fall is refluxed, the 13rd, the biphase gas and liquid flow distributing damper, the 14th, the burner fire hole, the 15th, gas nozzle, it can be single hole, annular aperture or porous, the 16th, unnecessary toner solutions return duct, the 17th, the toner solutions capillary syring, the 18th, the Pressure-stabilizing pressure reducing valve, conventional spring diaphragm type gets final product, its entrance point communicates with the fuel cartridge gas circuit, and its port of export communicates with the gas nozzle gas circuit.

Embodiment one: make the color fireworks torch of the hand-held formula of sportsman, structure as shown in Figure 1, except that the toner solutions feed mechanism, all the other can be similar with the combustion gas fire generation of prior art.

Embodiment two: make the fixed torch in megaevent meeting-place, as shown in Figure 2, can there be a plurality of toner solutions bunkers to adorn metal salt solution not of the same race respectively, control its capillary syring with controlling organization and communicate with the gas nozzle negative pressuren zone successively, then can make color fireworks torch send the plurality of color flame and increase festive air.

Embodiment three: the colored little torch of miniature " cured candle of the birthday " formula of making, and structure can be improved on lighter structure as shown in Figure 3, and injection molding can make birthday party increase new temperament and interest.

The utility model design innovation, rational in infrastructure, to make simple and easyly, cost almost is equal to prior art, and color flame effect is remarkable, has realized the goal of the invention of expecting, and market prospects are wide.

Claims (2)

1, a kind of device that produces colored flames, the fuel gas supply part that comprises the bottom, the combustion chamber on top, middle mixing chamber makes upper and lower connection by controlling organization, there are automatic igniting and flame-out resume combustion mechanism in combustion chamber place, it is characterized in that: the toner solutions feed mechanism is arranged below mixing chamber, communicate with the fuel nozzle negative pressuren zone via the capillary syring that promotes colour former liquid liquid.
