Abstract

The utility model relates to a hopper with a ventilation function, wherein the outer surface of the hopper, formed into a tapered conical shape from top to bottom, is provided with a plurality of grooves, and a circular arc angle is formed at the position where the internal conical surface is adjacent to a straight hole; therefore, when the hopper is arranged in the opening of containers with different dimensions, filling and pouring operation can be successfully carried out by means of the grooves at the outer surface of the hopper under the condition that the internal pressure and the external pressure of the containers are the same, and filled and poured liquid can be smoothly output into the containers due to the circular arc angle formed at the position where the internal conical surface is adjacent to the straight hole, thus having practical function.

Description

The funnel of the ventilative effect of tool

Technical field

The utility model is the funnel of the ventilative effect of a kind of tool, be provided with the multiple tracks groove by the funnel outside face, and be arc angle at inner conical surface and straight hole adjacent position,, be able to do along ground, glibly the practical effect of filling the perfusion operation to provide when funnel places various vessel port size.

Background technology

Press, generally, form the convergent taper from top to bottom, and be bent angle A3, think for placing container B opening B1 to do to fill and pour into use at inner conical surface A1 and straight hole A2 adjacent position at the funnel A (as Fig. 1) of circulation on the market; Yet often take place behind the opening B1 that inner conical surface A1 and the straight hole A2 of funnel A go deep into container B, be to cause the space B 2 in the container B opening B1 to intercept outward with container B opening B1, though also have funnel A space A1 can with space B 2 in the container B opening B1 for communicating, when filling in after body C pours the space A1 of funnel A into, flow into toward the interior space B 2 of container B opening B1 always, the space A1 that causes funnel A also no longer with container B opening B1 in space B 2 for having communicated, space B 2 in the container B opening B1 is changed, so just form in the container B opening B1, outer air pressure overbalance, form one on the contrary and upwards push up the back-pressure power P (as Fig. 2) that dashes, therefore causing filling in body C then can't be smooth, flowed into the space B 2 in the container B opening B1 lentamente; Moreover; by present funnel A place inner conical surface A1 and straight hole A2 adjacent position mostly is bent angle A3 state; so that, but got lodged in the space A4 of funnel A when to fill in body C be to contain big particles or when being thick, just produce mobile resistance because of this bent angle A3 cause easily.

Therefore, the applicant exhausts research for many years then and develops the utility model down in view of above situation.

Summary of the invention

The purpose of this utility model is, the funnel of the ventilative effect of a kind of tool is provided, and it can be under the identical situation at the inside and outside air pressure of container, successfully does and fills the perfusion operation.

For achieving the above object, the utility model discloses the funnel of the ventilative effect of a kind of tool, it is characterized in that: forming from top to bottom when being provided with multiple tracks when funnel places various vessel port size on the funnel outside face of convergent taper can be successfully to do under the identical situation to fill the groove that perfusion is operated at the inside and outside air pressure of container.

Also disclose the funnel of the ventilative effect of a kind of tool, it is characterized in that: be provided with the pouring space in the vessel port into and do when filling the perfusion operation and form circulation status so that the inside and outside air pressure of container is successfully to do under the identical situation to fill the raised line that perfusion is operated of the slight projection of multiple tracks on the funnel outside face of convergent taper forming from top to bottom by the ventilation space that its periphery caused when filling in body.

Wherein, be arc angle in the inner conical surface and the straight hole adjacent position of funnel.

Pass through said structure, when funnel of the present utility model places various vessel port size, can be under the identical situation at the inside and outside air pressure of container all by groove on the funnel outside face or raised line, successfully realize filling the perfusion operation, and, be to be arc angle in the inner conical surface and the straight hole adjacent position of funnel; Be when funnel places various vessel port size, can export in the container more glibly.

The specific embodiment

At first, please cooperate and consult shown in Fig. 3, Fig. 4 detailed description: the funnel of the ventilative effect of a kind of tool of the utility model, on funnel 1 outside face that forms the convergent taper from top to bottom, be provided with multiple tracks groove 11, the width of its further groove 11 can be different shape (as Fig. 5-A, 5-B), and is arc angle in inner conical surface 12 and straight hole 13 adjacent positions; So be when funnel 1 places opening 21 sizes of various containers 2 (as Fig. 6, Fig. 7), when promptly inner conical surface 12 partly and straight hole 13 go deep into space 22 in container 2 openings 21, the opening 21 inside and outside air pressure of thinking container 2 by the groove 11 on funnel 1 outside face remain under the identical situation, fill in body 3 and successfully flow into space 22 in container 2 openings 21 and do and fill the perfusion operation when making, especially the back-pressure power Ps of space 22 when reducing gradually in these container 2 openings 21 follow by the groove 11 on funnel 1 outside face to arrange outward.

Simultaneously; be the arc angle cause by this funnel 1 inner conical surface 12 of the present utility model with straight hole 13 adjacent positions system again; can make and fill in body 3 is to contain big particles or all can export to glibly in the container 2 when thick, and the space that can not get lodged in funnel 1 stagnates.

In addition, also can on funnel 1 outside face, be provided with the raised line 14 (as Fig. 8) of the slight projection of multiple tracks; Think and similarly have above-described use effect, promptly pour space 22 in container 2 openings 21 into and do when filling the perfusion operation when filling in body 3, it is stream mode and arranging outward that the back-pressure power P that produces in the space 22 in these container 2 openings 21 satisfies the ventilation space that is caused by raised line 14 peripheries on funnel 1 outside face, so, making container 2 openings 21 inside and outside air pressure is under the identical situation, thinks successfully to do and fills the perfusion operation.

Certainly, no matter be that groove 11 or raised line 14 all can be made into different length and come also similarly have above-described use effect for using (as Fig. 9).

Claims
