Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a kind of novel alcohol torch is characterized in that: comprise lamp pot 1, alcohol lamp cap 2, nozzle tube 3, oil tin 4, ignition bowl 5, air conditioner 6 and fire spray tube 7; The pot 1 is provided with a connecting ring 8, the connecting ring 8 is connected with the pot neck 9, and the top of the pot neck 9 is provided with a shrinking external thread portion 10; A wick hole 12 is provided on the top end surface of the alcohol lamp cap 2; the nozzle tube 3 is set on the alcohol lamp cap 2 and the pot neck 9, and is connected with the connecting ring 8; the upper end of the nozzle tube 3 is provided with a spout 13; Heat conduction oil 21 is provided, the top of the oil tank 4 is connected to the ignition bowl 5, and the upper port of the ignition bowl 5 is provided with a card slot 14 and a slide rail 15; the air conditioner 6 includes an inner cover 6-1 and an outer cover 6-2, the The inner cover 6-1 is provided with a wind hole 16, the top of the inner cover 6-1 is connected with the fire pipe 7, and the bottom end of the inner cover 6-1 is provided with a buckle 17 matched with the ignition bowl slot 14. The outer cover 6-2 is connected with a handle 18, and the outer cover 6-2 is provided with an air hole two 19 corresponding to the air hole one 16, and the top of the outer cover 6-2 is provided with an opening 20, and is put through the fire pipe 7 and the inner cover 6-1 fold.

When in use, the lamp pot 1 and the alcohol lamp cap 2 are sealed and connected by threads to form the main part of the alcohol lamp. Alcohol is injected through the neck of the lamp pot 1, and several strands of wick extend into the lamp pot 1 through the wick hole 12 at the upper end of the lamp cap of the alcohol lamp; the nozzle The tube 3 replaces the cap of the alcohol lamp; thus the alcohol lamp is formed and used.

The nozzle pipe 3 is fixed on the pot neck 9 of the lamp pot 1 by being connected with the connecting ring 8, and implements the purpose of spraying gaseous alcohol from the nozzle of the blowtorch. The upper end of the alcohol lamp cap 2 and the lower end of the nozzle tube 3 form an inner cavity to store gaseous alcohol, forming a spray pressure.
