Abstract
The utility model discloses a kind of Simple heat insulation funnel, comprise headwall and lower pipe, described headwall and lower pipe are the double-decker of hollow; The top of described headwall is provided with two through holes; Described through hole communicates with the hollow layer of described headwall; The side of described headwall is provided with a closed projection; Described projection is hollow structure; The hollow layer of described projection communicates with the hollow layer of described headwall and described lower pipe; The opposite side of described headwall is provided with one and grabs ring.The utility model structure is simple, easy-to-use, has heat insulation function.
Description
Technical field
The utility model relates to a kind of experimental ware, particularly relates to a kind of hot funnel with certain heat insulation function of chemical experiment.
Background technology
At present, for the simple glass funnel of scientific research, chemical experiment, be the vessel of transfer and filter liquide, be generally individual layer headwall structure.The deficiency of this funnel is, funnel headwall is single layer structure, and the direct contact environment of headwall makes the heat in bucket between liquid and environment easily transmit; For the experimental implementation having temperature requirement, this funnel can not play the effect of insulation, is difficult to satisfied corresponding requirement of experiment.
Summary of the invention
The purpose of this utility model is to provide a kind of hot funnel with certain heat insulation function of chemical experiment.
What the utility model solved is the defect that the funnel of existing individual layer headwall structure cannot play insulation effect in experimentation.
The technical scheme that the utility model technical solution problem adopts is: a kind of Simple heat insulation funnel, comprises headwall and lower pipe, and described headwall and lower pipe are the double-decker of hollow; The top of described headwall is provided with two through holes; Described through hole communicates with the hollow layer of described headwall; The side of described headwall is provided with a closed projection; Described projection is hollow structure; The hollow layer of described projection communicates with the hollow layer of described headwall and described lower pipe; The opposite side of described headwall is provided with one and grabs ring.
Described hot funnel is copper.
Described projection is cylinder.
The beneficial effects of the utility model are: compared with prior art, and the utility model structure is simple, easy-to-use, has heat insulation function.For the experimental implementation having temperature requirement, experimentation is not by the impact of ambient temperature, and observed data is accurate, is the good experimental ware of a kind of function in scientific research, chemical experiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of Simple heat insulation funnel, comprises headwall 3 and lower pipe 4, and described headwall and lower pipe are the double-decker of hollow; The top of described headwall is provided with two through holes 1; Described through hole communicates with the hollow layer of described headwall; The side of described headwall is provided with a closed cylindrical projection 5; Described projection is hollow structure; The hollow layer of described projection communicates with the hollow layer of described headwall and described lower pipe; The opposite side of described headwall is provided with one and grabs ring 2.Described hot funnel is copper.
