Abstract

The utility model relates to a modified safe alcohol lamp used for a teaching experiment. The modified safe alcohol lamp used for the teaching experiment comprises a lamp body. A lamp port is arranged on the lamp body, and the lamp port is provided with a rubber plug in sealed mode. A core pipe is disposed in the rubber plug, and a wind-fire shield is arranged at the upper end of the core pipe. An air pipe is arranged between a wick and the core pipe. A lead-made base is arranged at the bottom end of the lamp body, and the lamp body is fixedly provided with an article placing frame. The arrangement of the rubber plug and the air pipe can prevent alcohol from volatilization and enables the alcohol lamp to be filled with alcohol; the arrangement of the wind-fire shield enables the lamp port of the alcohol lamp to be free from being heated, so the technical problem of easy explosion of the lamp port of the lamp body due to uneven heating is resolved; the arrangement of the lead-made base enables the gravity center of the alcohol lamp to be lower than the maximum cross section of the alcohol lamp, and when the alcohol lamp inclines due to the action of external forces, the alcohol lamp self can return to an upright state due to the action of gravity and is not easy to tip over; and due to the arrangement of the article placing frame, and articles can be directly placed on the article placing frame to be heated, so the modified safe alcohol lamp used for the teaching experiment is simple, safe and convenient to use.

Description

Improved 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 improved 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: improved 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; The bottom of said lamp body and said base are formed the shape of falling the billiard table, and said lamp body is installed with the article rack.

The utility model is taked above technical scheme, has the following advantages: improved 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; The bottom of said lamp body and said base are formed the shape of falling the billiard table, and said lamp body is installed with the article rack; 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, not prone to tip over, and the setting of article rack voluntarily; Heated directly is placed on the article rack gets final product, use simple, safety, convenience.

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

The specific embodiment

Embodiment: improved 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, and said lamp body 2 is installed with article rack 9.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, not prone to tip over, and the setting of article rack 9 voluntarily; Heated directly is placed on the article rack 9 gets final product, use simple, safety, convenience.
