Abstract
The utility model provides a non-bubbling funnel, which comprises an open funnel top for pouring liquid and an internal thread arranged on the inner peripheral surface of the bottom end of the funnel top; the outer peripheral surface of the top part is provided with a funnel bottom part of an external thread which can be in threaded connection with the internal thread, and the top part of the funnel bottom part is also in threaded connection with a nut which prevents the funnel bottom part from being completely separated from the funnel top part; a spiral groove formed on the outer peripheral surface of the bottom of the funnel and used for discharging air; a plurality of vent holes for better ventilating the bottom of the funnel are also arranged on the top of the funnel in a penetrating way; the ventilation effect of the funnel bottom can be better through penetrating through the vent holes arranged on the funnel bottom, namely, even if the end face of the funnel bottom is submerged by the liquid level and liquid injection is continuously carried out, no air bubble can occur, because air can be discharged out of the funnel bottom through the vent holes.
Description
Technical Field
The utility model relates to a funnel, especially a funnel that does not bubble.
Background
Funnel, like a kind of refueling exhaust funnel of national patent publication No. CN204369554U, funnel (1) outer wall has spiral recess (2), spiral recess (2) extend to the upper portion export of funnel (1) from funnel (1) end opening. The funnel is characterized in that a vent pipe (3) is arranged on the inner wall of the funnel (1), and the vent pipe (3) is communicated to the top of the funnel (1) from the bottom of the funnel (1). Breather pipe (3) are the rubber tube, the rubber tube bonds in funnel (1) inner wall, and the funnel (1) upper shed is stretched out to the upper end of rubber tube, and the lower extreme and the funnel (1) end opening of rubber tube flush. The spiral groove (2) extends from the lower opening of the funnel (1) to the top of the funnel (1). The spiral grooves (2) are arranged at equal intervals;
in the funnel, because the funnel is designed integrally, the top and the bottom of the funnel are fixed, the funnel cannot be adjusted according to the height of the bottle body and the liquid level of the liquid, if the liquid level is close to the bottom of the funnel, the outer wall of the funnel can be wetted, and the funnel cannot be taken subsequently;
in particular, it should be noted that the above-mentioned funnel has a drawback that when the liquid level completely passes the end of the bottom of the funnel, if the filling action is continued, bubbles still appear, because the space in the funnel extending into the bottle needs to be filled at this time, so that the gas in this part of the space needs to be discharged, and the above-mentioned spiral groove (2) is arranged on the outer peripheral surface of the funnel, so that the normal air exhausting function is not performed in this case, and thus an adjustable non-bubbling funnel is provided.
Disclosure of Invention
The design objective of the utility model is, in view of the above-mentioned problem, provide an adjustable funnel overall height does not bubble funnel.
The technical proposal for solving the technical problem comprises that,
the inner circumferential surface of the top of the funnel and the bottom of the top of the funnel which are used for pouring liquid and are arranged in an open mode is provided with internal threads;
the outer peripheral surface of the top part is provided with a funnel bottom part of an external thread which can be in threaded connection with the internal thread, and the top part of the funnel bottom part is also in threaded connection with a nut which prevents the funnel bottom part from being completely separated from the funnel top part;
a spiral groove formed on the outer peripheral surface of the bottom of the funnel and used for discharging air;
a plurality of vent holes for better ventilating the bottom of the funnel are also arranged on the top of the funnel in a penetrating way;
the inner circumferential surface of the bottom of the funnel is also fixedly provided with a vent pipe, one end of the vent pipe is positioned at the side of the bottom end part of the bottom of the funnel, and the other end of the vent pipe is positioned above the top of the funnel.
Preferably, the total length of the external thread on the bottom of the funnel accounts for one third of the total length of the bottom of the funnel.
Preferably, the total length of the spiral grooves on the bottom of the funnel accounts for two thirds of the total length of the bottom of the funnel;
the cross section of the spiral groove is rectangular.
Preferably, the vent holes are arranged on the top of the funnel and beside the spiral groove, and the distance between two adjacent vent holes is the same.
The beneficial technical effect of this application: the assembled funnel, namely the funnel bottom and the funnel top which are connected by screw threads and have adjustable overall length can ensure that the funnel bottom is far away from the liquid level as far as possible when in use, thereby facilitating the taking of the funnel by a user; the ventilation effect of the funnel bottom can be better through penetrating through the vent holes arranged on the funnel bottom, namely, even if the end face of the funnel bottom is submerged by the liquid level and liquid injection is continuously carried out, no air bubble can occur, because air can be discharged out of the funnel bottom through the vent holes.
Drawings
FIG. 1 is a schematic view of the structure of the present invention;
fig. 2 is another schematic structural diagram of the present invention in use.
Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings so as to facilitate the further understanding of the present invention by those skilled in the art, and do not limit the right thereto.
Example 1, referring to fig. 1-2, a non-bubbling funnel, comprising,
the inner circumferential surfaces of the top 1 of the funnel and the bottom end of the top 1 of the funnel which are used for pouring liquid and are arranged in an open mode are provided with internal threads;
the periphery of the top of the funnel is provided with a funnel bottom 3 of an external thread 2 which can be in threaded connection with the internal thread, and the top of the funnel bottom 3 is also in threaded connection with a nut 4 which prevents the funnel bottom 3 from being completely separated from the funnel top 1;
a spiral groove 5 formed on the outer circumferential surface of the funnel bottom 3 for discharging air;
a plurality of vent holes 6 for better ventilating the bottom 3 of the funnel are also arranged on the top 1 of the funnel in a penetrating way;
a vent pipe 7 is fixedly arranged on the inner circumferential surface of the bottom part 3 of the funnel, one end of the vent pipe 7 is positioned at the side of the bottom end part of the bottom part 3 of the funnel, and the other end is positioned above the top part 1 of the funnel. The cross section of the funnel top 1 is arranged in a circular ring shape; the funnel top 1 is in an open arrangement, i.e. open at the top and open at the bottom.
Example 2, a non-bubbling funnel as described in example 1, wherein the total length of the external thread 2 on the bottom 3 of the funnel is one third of the total length of the bottom 3 of the funnel.
Example 3, a non-bubbling funnel as described in example 2, wherein the overall length of the spiral grooves 5 on the bottom 3 of the funnel is two thirds of the total length of the bottom 3 of the funnel;
the cross section of the spiral groove 5 is rectangular.
When the non-bubbling funnel is used, the whole length of the funnel is controlled by the design of the external thread 2 and the internal thread, namely the bottom 3 of the funnel is rotated according to the depth of a bottle mouth or the liquid level position of liquid to be poured in a bottle body, and the bottom 3 of the funnel is placed in the bottle after adjustment, during which, when the liquid level completely submerges the end surface of the bottom 3 of the funnel, the liquid is continuously poured;
it should be noted that, because the funnel bottom 3 stretches into the bottleneck, so the bottle does not fill completely at this moment and needs to annotate the liquid action continuously, and the gaseous when annotating the liquid reaches spiral groove 5 department through air vent 6 and discharges the bottle this moment and can reach the whole technological effect that does not bubble, and the design among the prior art is more reliable, practical.
