Abstract

The utility model relates to a safe alcohol lamp for teaching experiments. The safe alcohol lamp comprises a lamp body, wherein the lamp body is provided with a lamp socket; a rubber plug is mounted at the lamp socket in a sealing manner; the rubber plug is internally provided with a core tube; the upper end of the core tube is provided with a wind-fire baffle; the core tube is internally provided with a lamp wick; a ventilation pipe is mounted between the lamp wick and the core pipe; the bottom end of the lamp body is fixedly provided with a base made of lead; the lower part of the lamp body and the base compose an inverted ball table shape; the rubber plug and the ventilation pipe are arranged to prevent volatilization of alcohol and enable the alcohol lamp to be filled up with alcohol; the wind-fire baffle is arranged to prevent the lamp socket of the alcohol lamp from being heated, thereby solving the technical problem that the lamp socket of the alcohol lamp is easy to explode due to uneven heating; the base made of lead is arranged to enable the center of gravity of the alcohol lamp to be lower than the maximum cross section of the alcohol lamp; and when the alcohol lamp inclines under the action of an outer force, the alcohol lamp can restore the upright state automatically due to the action of gravity of the base and is not easy to turn over. The safe alcohol lamp for teaching experiments, disclosed by the utility model, is simple, safe and convenient to use.

Description

Teaching test is used safe alcohol lamp

Technical field

The utility model relates to a kind of teaching aid, relates to a kind of alcolhol burner specifically.

Background technology

Make experiment alcolhol burner commonly used at present in the teaching, sealing is connected socket with core Guan Weifei, and alcohol is brought into play easily in the use; And the alcohol addition can not exceed capacity 2/3; Forbid using the mouth flame blow-off, and the socket of alcolhol burner because bursting easily, the inequality of being heated overflows alcohol; Cause the danger that burns out article, burn teachers and students, influence teachers and students' safety.

The utility model content

The problem that the utility model will solve is to above problem, provides that a kind of to have solved alcohol volatile, and the be heated teaching test of the technical problem that inequality is prone to burst of alcolhol burner socket is used safe alcohol lamp.

For addressing the above problem, the technical scheme that the utility model adopted is: teaching test is used safe alcohol lamp, comprises lamp body; Said lamp body is provided with socket, and said socket place is sealed and installed with plug, and the core pipe is installed in the said plug; Said core pipe upper end is provided with wind fire retaining, and said wind fire gear is in the outside of said socket, and said wind fire retaining is greater than said socket; In the said core pipe wick is installed; Between said wick and the said core pipe breather pipe is installed, the bottom of said lamp body is installed with plumbous system base, and the bottom of said lamp body and said base are formed the shape of falling the billiard table.

The utility model is taked above technical scheme, has the following advantages: teaching test is used safe alcohol lamp, comprises lamp body; Said lamp body is provided with socket, and said socket place is sealed and installed with plug, and the core pipe is installed in the said plug; Said core pipe upper end is provided with wind fire retaining, and said wind fire gear is in the outside of said socket, and said wind fire retaining is greater than said socket; In the said core pipe wick is installed; Between said wick and the said core pipe breather pipe is installed, the bottom of said lamp body is installed with plumbous system base, and the bottom of said lamp body and said base are formed the shape of falling the billiard table; Being provided with of plug and breather pipe can prevent the alcohol volatilization, and can make alcolhol burner fill it up with alcohol, and the setting of wind fire retaining makes the alcolhol burner socket avoid being heated; Thereby solve the alcolhol burner socket uneven technical problem that bursts easily of being heated, the setting of plumbous system base lets the center of gravity of alcolhol burner be lower than the maximum cross section of alcolhol burner; When alcolhol burner is tilted by the external force effect; Because the gravity interaction energy of base recovers erectility voluntarily, not prone to tip over uses simple, safety, convenience.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Description of drawings

Accompanying drawing is the structural representation of the utility model embodiment.

Among the figure: the 1-base; The 2-lamp body; The 3-socket; The 4-plug; 5-core pipe; 6-wind fire retaining; The 7-wick; The 8-breather pipe.

The specific embodiment

Embodiment: teaching test is used safe alcohol lamp, comprises lamp body 2, and said lamp body 2 is provided with socket 3; Said socket 3 places are sealed and installed with plug 4, in the said plug 4 core pipe 5 are installed, and said core pipe 5 upper ends are provided with wind fire retaining 6; Said wind fire retaining 6 is positioned at the outside of said socket 3; And said wind fire retaining 6 is equipped with wick 7 greater than said socket 3 in the said core pipe 5, between said wick 7 and the said core pipe 5 breather pipe 8 is installed; The bottom of said lamp body 2 is installed with plumbous system base 1, and the bottom of said lamp body 2 and said base 1 are formed the shape of falling the billiard table; The diameter of said breather pipe 8 is that 0.3mm is best.Being provided with of plug 4 and breather pipe 8 can prevent the alcohol volatilization, and can make alcolhol burner fill it up with alcohol, and the setting of wind fire retaining 6 makes alcolhol burner socket 3 avoid being heated; Thereby solve the alcolhol burner socket uneven technical problem that bursts easily of being heated, the setting of plumbous system base 1 lets the center of gravity of alcolhol burner be lower than the maximum cross section of alcolhol burner; When alcolhol burner is tilted by the external force effect; Because the gravity interaction energy of base 1 recovers erectility voluntarily, not prone to tip over uses simple, safety, convenience.
