To ensure that it is brought into close contact；Wick end has a bamboo fibre ball, and described bamboo fibre ball center has perforate, and wick is by wearing
Hole is brought into close contact with bamboo fibre ball.
Described lamp body is arranged to Pear-Shaped, experimenter can be facilitated to grip, and alcolhol burner is difficult to slide.Preferably, institute
Most narrow place is that it is 1 apart from the ratio of the distance of lamp body bottom apart from the distance of lamp body neck in the middle of the lamp body stated:1-4:1, it is excellent
Elect 2 as:1, the gripping safety coefficient in alcolhol burner body now is higher.
Alcolhol burner lateral opening can be used for adding alcohol, and it is big that it directly adds alcohol security relative to tradition from bottleneck
Big increase, and can keep in lamp body during alcolhol burner use that oxygen is sufficient so that the flammability of wick is more preferable.It leads to
Cross screw nut mode to connect so that the good seal performance of alcolhol burner, alcohol will not be spilt in the moving process of alcolhol burner.
Heat insulation sealing gasket below the wick holder is prepared by heat-barrier material, is primarily served both sides and is acted on, and one
It is that can isolate heat during alcolhol burner use to transmit to lamp body so that the probability that hardening cracks of the neck of lamp body is substantially reduced；
Two be the volatilization that alcohol is reduced in alcolhol burner placement process, so that the combustion efficiency of alcolhol burner is more preferable.Preferably, it is described
The thickness of heat insulation sealing gasket be not less than 0.2 centimetre.
Described bamboo fibre ball is located at the end of wick, and its main function is that it, which is located at end, can play weight ring
Effect, so that alcohol is largely immersed in cotton core end.Two be that its absorption alcohol effect is more preferable than cotton core, is prepared into ball
Shape is also easier to make mobility of the alcohol in lamp body in cotton core more preferable.Therefore, the presence of bamboo fibre ball can cause alcohol
The combustion efficiency of lamp is more preferable.Preferably, described bamboo fibre ball is not more than three points of the length of wick to the distance of wick end
One of.
The utility model compared with prior art, itself it is a technical advantage that：
1）The shape of alcolhol burner is more easy to grip in the utility model, and its security performance is more preferable during for high school chemical experiment,
The service life of alcolhol burner can be extended.
2）It is of the present utility model by between wick holder and lamp body set heat-insulating and sealing circle can not only reduce lamp body neck
Probability is hardening cracked in portion, and can reduce alcohol volatilization, more preferably saves.
3）The present invention can cause alcolhol burner using by setting bamboo fibre ball in sidewall opening and on cotton core
Oxygen supply is more preferably abundant in journey, and mobility of the alcohol in cotton core is more preferable, so as to ensure that the combustion efficiency of alcolhol burner.
