Description
Technical field
The utility model is related to a kind of experimental article field more particularly to a kind of new funnels.
Background technology
Funnel is common a kind of instrument in laboratory, and when experiment needs circular filter paper being folded into and funnel sizes kissing
The inverted conical of conjunction, is put into funnel and is filtered, since filter paper is close to inner wall of hopper completely, because being pushed on funnel and funnel
The influence that inner wall hinders is oozed under filtrate slowly, and the rate of filtration is very slow, in addition the processing to filter paper, generally requires more than ten even
Dozens of minutes could complete the filtration step in experiment.
Utility model content
The technical issues of the utility model solves, which is to overcome, above-mentioned to be existed in the prior art deficiency and provides a kind of new
Funnel.
A kind of new funnel, including funnel body, filter cloth and the filler cap arranged on described funnel body one end；It is described
Funnel body outer wall is equipped with compress groove and the press strip mutually agreed with the compress groove, and the compress groove is used to accommodate
The junction portion of the filter cloth, the press strip are used to the filter cloth being pressed on the funnel body；The filler cap
Push rod and piston including cap tube, in cap tube, pushing and pressing part and the push rod phase of the piston by described push rod one end
Connection；The funnel body is detachably connected with the filler cap.
As further improved, the funnel body outer wall is provided with external screw thread, and the filler cap connects with funnel body
The position connect is correspondingly arranged on internal thread, and the funnel body is connected through a screw thread with filler cap.
As further improved, the funnel body outer wall is provided with card nose, and the filler cap is connected with funnel body
Position be correspondingly arranged on card slot, the funnel body is connected by a snap with filler cap.
As further improved, the thickness of filter cloth is defined as D, and the depth of the compress groove is 1.5D-2.5D.
As further improved, the thickness of filter cloth is defined as D, and the depth of the compress groove is 1.8D-2.2D.
As further improved, the compress groove is annular groove.
As further improved, the press strip is the sealing ring mutually agreed with the compress groove.
The utility model compared with prior art, the advantage is that：First, the utility model passes through press strip and compress groove
Cooperation, make filter cloth without folding, so as to fulfill the effect of filtering is accelerated；Second, the utility model is simple in structure, make
With convenient, and improve conventional efficient；Third, the utility model, with pressure principle, is accelerated filtrate and accelerates speed by push rod
Degree；It fourth, the utility model replaces filter paper with filter cloth, can try out repeatedly, save experiment material.

Fig. 2 is the partial enlarged view that the funnel body of the utility model embodiment and filler cap are threadedly coupled；
Fig. 3 is the partial enlarged view that the funnel body of the utility model embodiment and filler cap snap connection；
Fig. 4 is the filler cap structure diagram of the utility model embodiment；
Fig. 5 is the pusher structure schematic diagram of the utility model embodiment.
Specific embodiment
Further details of elaboration is done to the utility model below in conjunction with attached drawing.
A kind of new funnel of the utility model as illustrated in the accompanying drawings from 1 to 3, (is not marked including funnel body 1, filter cloth in figure
Show) and filler cap 2 arranged on described 1 one end of funnel body；1 outer wall of funnel body be equipped with compress groove 3 and with institute
The press strip 4 that compress groove mutually agrees with is stated, the compress groove 3 is used to accommodate the junction portion of the filter cloth, and the press strip 4 is used
In the filter cloth is pressed on the funnel body 1；The filler cap 2 includes cap tube 21, the push rod in cap tube 21
22 and piston 23, the piston 23 be connected by the pushing and pressing part 24 of described 21 one end of push rod with the push rod 21；The funnel
Body 1 is detachably connected with the filler cap 2.
In other implementations, 1 outer wall of funnel body is provided with external screw thread 11, and the filler cap 2 connects with funnel body 1
The position connect is correspondingly arranged on internal thread 25, and the funnel body 1 is connected through a screw thread with filler cap 2.
In other implementations, 1 outer wall of funnel body is provided with card nose 12, and the filler cap 2 is connected with funnel body 1
Position be correspondingly arranged on card slot 26, the funnel body 1 is connected by a snap with filler cap 2.
In general, the thickness of filter cloth is about 0.5 μm, the depth of the compress groove 3 is about 0.75 μm -1.25 μm,
Preferably, the depth of the compress groove 3 is about 0.9 μm -1.1 μm, so as to preferably accommodate filter cloth.
In other implementations, the compress groove 3 is annular groove, and the press strip 4 is to agree with 3 phase of compress groove
Sealing ring (not indicated in figure), directly agreeing with room filter cloth by sealing ring and annular groove can preferably stablize in institute
It states on funnel body 1.
When being filtered, by filter cloth place funnel body 1 in, by compress groove 3 with press strip 4 connecing filter cloth
Head portion compresses are on funnel body 1, then pour into experimental liquid, are then connected filler cap 2 with funnel body 1, while to mistake
Filter cloth plays pressuring action again, promotes push rod 22, by pushing and pressing part 24 piston 23 is promoted to move up and down, utilizes funnel body 1
Interior pressure principle accelerates filtrate infiltration rate, saves experimental period.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
The spirit of utility model and any modification, equivalent substitution, improvement and etc. within principle, done, should be included in the utility model
Within the scope of protection.
