Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: an anti-overflow alcohol lamp fuel adding device comprises an alcohol lamp body 1, wherein a feeding structure 2 is assembled at the left end of the alcohol lamp body 1, a sealing structure 3 is assembled at the left end of the alcohol lamp body 1, and the sealing structure 3 is positioned above the feeding structure 2;

through reinforced structure 2 reinforced to alcohol burner body 1 in, avoid alcohol burner body 1 in the experimentation, improve the experimental effect, seal up reinforced structure 2 through seal structure 3, avoid alcohol to volatilize.

The feeding structure 2 comprises an L-shaped pipe 21 penetrating through the left side wall surface of the alcohol lamp body 1, a funnel 22 is assembled at the upper end of the L-shaped pipe 21, a pressure relief hole 23 is formed in the vertical end of the L-shaped pipe 21, and a pressure relief piece 24 is assembled on the pressure relief hole 23.

When feeding in to alcohol burner body 1, pour into funnel 22 with alcohol at the uniform velocity in, alcohol flows in to alcohol burner body 1 along L type pipe 21, and when the alcohol that leads to in the funnel is too much because the hand is trembled, the pressure increase in the L type pipe 21 carries out the slow-pressing through slow-pressing piece 24, avoids alcohol to spill over from funnel 22.

The sealing structure 3 comprises a rotating rod 31 which runs through the left side wall surface of the alcohol lamp body 1 in a rotating mode, the rotating rod 31 is located at the inner end of the alcohol lamp body 1 and is assembled with a sealing plate 32, the rotating rod 31 is located at the outer end of the alcohol lamp body 1 and is assembled with a rotating disc 33, and the sealing plate 32 is close to the left side wall surface side of the inner cavity of the alcohol lamp body 1 and is in contact connection with the left side wall surface.
