Description
Technical field
The utility model is related to test experience Instrument technology field, particularly a kind of funnel.
Background technology
Funnel is common a kind of instrument in laboratory, common funnel in existing laboratory, and shape is generally inverted cone
Barrel of funnel is combined with the connection of thin cylinder filler tube.When being filtered, funnel is closely connected with vessel port.Filtering certain hour
Afterwards, hyperbaric environment is easily formed in container, the rate of filtration and filter efficiency is influenceed, or even liquid level is no longer declined.
Regarding to the issue above, the Chinese patent of Publication No. CN204434258U discloses a solution；
The program is specially a kind of funnel of anti-blocking, including funnel upper oral part and funnel pipe portion, and the funnel is provided with ventilation
Passage, the venting channels are included in the fin that the outside of funnel is longitudinally provided with along funnel upper oral part to funnel pipe portion, when using
During the funnel, funnel pipe portion is stretched into vessel port, and prominent rib is stuck in vessel port, and the both sides of rib can form one with vessel port respectively
Individual gas passage, the cross section of the fin is triangle, square or trapezoidal.
The funnel makes the air pressure in container be communicated with atmospheric pressure due to the setting of gas passage so that hold in filter process
The larger situation of pressure will not be produced in device, so as to avoid the occurrence of in funnel liquid without situation about being dripped in normal direction container, but should
Funnel can only be filtered with the diameter of vessel port when directly using less than the container of funnel upper oral part diameter, when the appearance of container
The diameter of device mouthful is accomplished by first being fixed funnel using support when being slightly larger than funnel upper oral part diameter again stretches funnel pipe portion
Enter vessel port to be filtered so that funnel is poor with the suitability of bearing container.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of funnel, and funnel energy basis is held
The vessel port diameter for connecing container is adjusted, the suitability of enhancing funnel and bearing container.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of funnel, including barrel of funnel and filler tube, barrel of funnel side wall top are provided with mounting cup, are cut with scissors on mounting cup
It is connected to some around the symmetrically arranged arch sheet that can be overturn in vertical direction in barrel of funnel axle center, arch sheet one end and barrel of funnel bottom
Abut, limited block is provided with the mounting cup, deployable extremely the abutting with limited block of the arch sheet is in arch sheet two ends
In same level.
Using said structure, the container port radius of the bearing container below funnel are more than the radius of filler tube and less than arch
Shape plate launch when arch sheet end away from barrel of funnel axle center apart from when, all without additionally use support, so as to enhance funnel with
The suitability of bearing container；
Simultaneously because the arch face of arch sheet is set, when the vessel port of bearing container is smaller need not launch arch sheet, will leak
Bucket is placed on when on bearing container, and arch sheet is contacted with vessel port, and such bearing container is by the sky between arch sheet and arch sheet
Gap is identical with outside atmosphere, and hyperbaric environment will not be formed in such container, does not interfere with the rate of filtration, and working as needs arch sheet
Funnel is placed on when on bearing container after expansion, same bearing container can by the space between arch sheet and arch sheet with it is outer
Portion's air is identical, so as to not interfere with filter efficiency.
It is further arranged to the barrel of funnel inwall and is provided with a circle for stopping the stop circle of filter paper around inwall.
Using said structure, when filtering filter paper is placed on barrel of funnel inwall, can be by stopping circle by filtering filter paper
Portion is blocked, so as to avoid filter paper in filter process from being moved influence filter effect.
It is further arranged to the filler tube lower end and is set to scarf.
Using said structure, filtrate flows out filler tube in compared to filler tube lower end being provided in round that funnel can be accelerated,
Strengthen filter efficiency.
It is further arranged to the barrel of funnel edge and is provided with handle.
Using said structure, the setting of handle is convenient to take to funnel.
It is further arranged to be provided with anti-slip veins on the handle.
Using said structure, the setting of anti-slip veins can strengthen the frictional force of finger and anti-slip veins, prevent funnel from falling from hand
Fall to breaking into pieces.
It is further arranged to be provided with graduation mark on the barrel of funnel.
Using said structure, the volume of solution in funnel can be judged according to graduation mark.
In sum, the utility model has the advantages that：
1. funnel is stronger with the suitability of bearing container, can use larger diameter scope in the case where support is not used
Container as funnel direct support container；
2. there is filter efficiency higher, connected state is in external pressure by making bearing container, enhance this
The filter efficiency of funnel.

Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of funnel, as Figure 1-Figure 2：Including barrel of funnel 1 and filler tube 2 that glass material is made, set on barrel of funnel 1
Graduation mark 8 is equipped with, the inwall of barrel of funnel 1 is provided with a circle for stopping the stop circle 6 of filter paper around inwall, and the edge of barrel of funnel 1 sets
Handle 7 is equipped with, anti-slip veins are provided with handle 7, the lower end of filler tube 2 is set to scarf；
The side wall top of barrel of funnel 1 is provided with the mounting cup 3 of transparent plastics material, and 3 are hinged with mounting cup 3 can be vertical
4,3 arch sheets 4 of arch sheet of direction upset are symmetrical arranged around the axle center of barrel of funnel 1, and arch sheet 4 is transparent plastics material, arch
The one end of plate 4 is abutted with the bottom of barrel of funnel 1, and limited block 5 is provided with mounting cup 3, and arch sheet 4 is deployable extremely to abut with limited block 5
The two ends of arch sheet 4 are made to be in same level.
Operation principle：Maximum gauge of the container port radius of the bearing container 0 below funnel more than the upper oral part of barrel of funnel 1
When, deployable arch sheet 4 makes arch sheet 4 be abutted with limited block 5, and just the arch sheet 4 on barrel of funnel 1 can be shelved on into undertaking holds
In the vessel port of device 0, then filter paper block just can be carried out into filter operation in stop circle 6, so enhance funnel and accept
The suitability of container 0；
Simultaneously because the arch face of arch sheet 4 is set, and when the vessel port of bearing container 0 is smaller need not launch arch sheet 4, will
Funnel is placed on when on bearing container 0, and arch sheet is contacted with 4 vessel ports, such bearing container 0 by arch sheet 4 and arch sheet 4 it
Between space it is identical with outside atmosphere, hyperbaric environment will not be formed in such bearing container 0, do not interfere with the rate of filtration, and work as
Funnel is placed on when on bearing container 0 after needing to launch arch sheet 4, same bearing container 0 can pass through arch sheet 4 and arch
Space between plate 4 is identical with outside atmosphere, so as to not interfere with filter efficiency.
This specific embodiment is only that, to explanation of the present utility model, it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected by Patent Law in right of the present utility model.
