Abstract

The utility model relates to a funnel, which is suitable for leading fluid of liquid, colloid, etc. to containers with small entry caliber after fluid transferring. The utility model is mainly composed of a cup body (1), an educing pipe (2), and an exhausting pipe (3); or is composed of a cup body (1), an educing pipe (2), and an exhausting pipe (7). The utility model has the advantages of simple structure, convenient and safe use, anti-flooding, and no splashing, and which can improve efficiency and avoids losses.

Description

Funnel

The utility model belongs to the instrument that pours into aqueous material.

Existing commercially available funnel generally is made up of cup and delivery line, as fluids such as liquid and colloid being input to the intermediary utensil of inlet mouth in less container.In use, delivery line is inserted container entrance, inject certain fluid through funnel, original gas pressurized in the container is also discharged through delivery line simultaneously, and produces bubble, hinders the injection of fluid.The fluid that injects in cup more also can splash or overflow, if what inject is strong acid, agricultural chemicals etc., also can spills and hurt sb.'s feelings or decrease dirty clothing and cause waste.

The purpose of this utility model is to provide a kind of funnel that special exhaust passage is arranged, have service efficiency height and safe ready.

In order to achieve the above object, the designed structure of the utility model is that a kind of funnel is made up of cup (1) and delivery line (2).Cup (1) is widely different the turning of hollow thin-wall that open topped, bottom have outlet, and delivery line (2) is the Taper Pipe shape, and the outlet of its big end and cup (1) bottom is connected, and it is characterized in that being provided with the exhaust passage inside and outside the tube wall of delivery line (2).

For the less funnel of delivery line (2) internal diameter, generally the outside face at delivery line (2) is provided with exhausr port (3), its shape is spill, being provided with the another kind of structure of exhausr port (3) along delivery line (2) outside face is to overlap the solid pipe exhaust ring (4) of a ring-type at the outside face of delivery line (2), this circle surface distribution has a muscle (5) of projection, and two adjacent grooves that prop up between the muscle (5) are exhausr port (3).

The bigger funnel of internal diameter for delivery line (2), need particularly to prevent that some fluid is when the outside face of delivery line (2) and the hole between container overflow, can on the lower end tube wall of delivery line (2), open side opening (6), one end of freeing pipe (7) is linked to each other with side opening (6), the other end is by in the cup (1), and the mouth of pipe communicates with the external world.

Be described further below in conjunction with drawings and Examples:

Fig. 1 is the structural representation that has the funnel of exhausr port;

Fig. 2 is the A-A section-drawing of Fig. 1;

Fig. 3 is the structural representation that has the funnel of solid pipe exhaust ring;

Fig. 4 is the B-B cutaway view of Fig. 3;

Fig. 5 is the structural representation that has the funnel of freeing pipe.

Funnel shown in Fig. 1 and Fig. 2 mainly is made up of cup (1), delivery line (2) and exhausr port (3).Cup (1) is widely different the turning of hollow thin-wall that open topped, bottom have outlet, can be the garden tubular, can be taper also, or taper etc. under the upper prop.Be provided with handle (9) on wall of cup, delivery line (2) is the Taper Pipe shape, and the outlet of its big end and cup (1) bottom is connected, and the two can be whole, and its material can be plastics, glass, also can be metal etc.At the exhausr port that circumferentially is distributed with spill (3) of delivery line (2) outside face, can be the groove of one group of shirt rim of delivery line (2) outside face, also can be along the groove between the rib of one group of projection of the axial distribution of delivery line (2) outside face.Exhausr port (3) and the gap of inserting between the container entrance of delivery line (2) are enough to make the gas in the container to be discharged effectively, and simultaneously, the small end aperture that can not make delivery line (2) reduces and influences the fluid input speed.

Can fix a line on handle (9), the other end of this line connects the choke plug (8) of frustum, and the small end external diameter of choke plug (8) is slightly less than the internal diameter of delivery line (2) upper end.Choke plug (8) also can be hollow or cap shape, can be by rubber, and plastic or other material is made, and can also establish the gripping hole on it.Line can be plastics, cotton thread or metallic bond etc.Clog delivery line (2) with stifled stream plug (8) and can block up stream.Can not establish choke plug (8) generally speaking.

Funnel shown in Fig. 3 and Fig. 4 is a kind of convenient form of considering on the basis of the above, can be at the solid pipe exhaust ring (4) of the ring-type of outside face cover of the delivery line (2) of the funnel in the existing commercially available or such scheme, a muscle (5) of establishing projection at inner ring surface and (perhaps) axial two ends (perhaps arbitrary end) of this circle.The shape of muscle (5) projection and be distributed with the fixing and exhaust that is beneficial to delivery line (2) and get final product, as be half garden cylindricality etc.Exhausr port (3) is two grooves between adjacent muscle (5), i.e. delivery line (2) and manage between the exhaust ring (4) admittedly and manage gap between exhaust ring (4) and the container entrance admittedly.

Funnel shown in Fig. 5 is to have side opening (6) on the tube wall of above-mentioned delivery line (2) lower end, and the tracheae (7) that runs in thereon, the other end of freeing pipe (7) stretches out in delivery line (2) and cup (1), and the interior sky that is injected into the container of certain fluid is connected with extraneous.Freeing pipe (7) can be plastics, also can be metallic material etc., and it does not hold the mouth of pipe should be higher than the top actinal surface of cup (1).

Outside face at freeing pipe (7) also can overlap a porose choke plug (8), is used for stifled stream in case of necessity.

The utility model is owing to the appearance at delivery line (2) is circumferentially with exhausr port (3) or manages exhaust ring (4) admittedly, perhaps in its tube chamber, be provided with freeing pipe (7), make the interior original gas of the container that is injected into fluid have dedicated channel to discharge, avoid and inject fluid and in same catwalk, drive in the wrong direction, improved service efficiency, and reached and prevent such as outer effect of spattering with overflow such as oil, wine or agricultural chemicals.

The utility model is the effective intermediary utensil that is used to transfer general liquid fluid, is applicable in daily life, production service and the experiment above-mentioned fluid is input to the inlet mouth in less container.
