Abstract
The utility model relates to an auxiliary tool for filling liquid, in particular to a funnel with an air pressure balancing mechanism. The funnel comprises a funnel main body, wherein an air pressure balance mechanism is arranged in the funnel main body; the air pressure balancing mechanism is an exhaust channel which is axially arranged on the funnel main body according to the shape of the shell wall of the funnel main body, and the exhaust channel is communicated from the top opening of the funnel main body to the bottom opening of the funnel main body up and down. The air exhaust channel is arranged in the shell wall of the funnel main body, when the funnel is used for filling liquid into the container, the air pressure inside and outside the container can be kept consistent through the air exhaust channel, so that the liquid overflow condition caused by the increase of the pressure in the container is effectively avoided, meanwhile, the funnel is suitable for containers with different calibers, and the air exhaust effect of the air exhaust channel is not influenced by the size of the container opening.
Description
Technical Field
The utility model relates to an auxiliary liquid filling tool, in particular to a funnel with an air pressure balancing mechanism.
Background
When filling a container with a small diameter, an operator generally needs to use a funnel. When the funnel is used, the container opening can be blocked by the funnel due to the concentrated addition of a large amount of liquid into the container, and the bottom opening of the funnel can be blocked by the liquid to be filled. Meanwhile, most of funnels in the market are not provided with an air pressure balance mechanism and do not have an air pressure balance function, so that the air pressure in the container can be increased in the process of filling liquid into the container, and when the air pressure in the container is increased to a certain degree, the liquid can be reversely sprayed or bubbled to overflow from the funnel. If the liquid to be filled has a certain damage to the skin of the human body, an accident can happen.
Currently, there is a funnel on the market, as shown in fig. 1, which comprises an upper conical body portion 1 and a lower cylindrical body portion 2, the side wall of the cylindrical body portion 2 being provided with axial degassing grooves 22. Such an exhaust funnel has the following drawbacks: if the caliber of the liquid container needs to be filled is large, after the funnel is inserted into the container opening, when the container opening is in contact with the position where the indicating line 11 is located, when an operator uses the funnel to fill liquid, the container opening is blocked by the funnel, the air release groove 22 cannot play a role in air release, and cannot play a role in air pressure balance, so that the air pressure inside and outside the container cannot be balanced, therefore, in the process of filling liquid into the container, the air pressure inside the container is increased, and when the air pressure is increased to a certain degree, the liquid can be reversely sprayed or bubbled and overflowed from the funnel.
Therefore, the funnels in the prior art have certain potential safety hazards, and need to be improved urgently.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to overcome the drawbacks of the prior art, and provides a funnel with an air pressure balancing mechanism to solve the above technical problems.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a from funnel of taking atmospheric pressure balance mechanism, includes the funnel main part, its characterized in that: an air pressure balance mechanism is arranged in the funnel main body; the air pressure balancing mechanism is an exhaust channel which is axially arranged on the funnel main body according to the shape of the shell wall of the funnel main body, and the exhaust channel is communicated from the top opening of the funnel main body to the bottom opening of the funnel main body up and down.
Preferably, the funnel main body sequentially comprises a top opening part, a liquid storage part and a liquid injection part from top to bottom; the top opening part is cylindrical, and the liquid storage part and the liquid injection part are inverted cones.
Preferably, an annular outer edge is arranged on the outer wall of the top opening part.
Has the advantages that: compared with the prior art, the air exhaust channel is arranged in the shell wall of the funnel main body, when the funnel is used for filling liquid into the container, the air pressure inside and outside the container can be kept consistent through the air exhaust channel, so that the liquid overflow condition caused by the increase of the pressure in the container is effectively avoided, meanwhile, the funnel is suitable for containers with different calibers, and the air exhaust function of the air exhaust channel is not influenced by the size of the container opening.
Drawings
FIG. 1 is a schematic diagram of a prior art exhaust funnel;
fig. 2 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The utility model is further described with reference to the following figures and specific embodiments.
Example (b):
referring to fig. 2, the funnel with the air pressure balancing mechanism of the present embodiment includes a funnel main body. The funnel main body sequentially comprises a top opening part 3, a liquid storage part 4 and a liquid injection part 5 from top to bottom; top mouthful of part 3 is cylindrical, stock solution part 4 and notes liquid part 5 are the back taper, it inserts the container intraoral to annotate liquid part 5 when using, also designs it for the back taper for the funnel is suitable for the scope of container bore bigger. The outer wall of the top opening part 3 is provided with an annular outer edge 6. The funnel comprises a funnel main body and is characterized in that an air pressure balance mechanism is arranged in the funnel main body, the air pressure balance mechanism is an exhaust channel 7 which is axially arranged on the funnel main body according to the shape of the shell wall of the funnel main body, and the exhaust channel 7 is communicated from the top opening of the funnel main body to the bottom opening of the funnel main body.
The air exhaust channel 7 is arranged in the shell wall of the funnel main body, when the funnel is used for filling liquid into the container, the air exhaust channel 7 can enable the air pressure inside and outside the container to be consistent, so that the liquid overflow condition caused by the increase of the pressure in the container is effectively avoided, meanwhile, the funnel is suitable for containers with different calibers, and the air exhaust effect of the air exhaust channel 7 is not influenced by the size of the container opening.
The foregoing shows and describes the fundamental principles, principal features and technical characteristics of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but various changes and modifications may be made without departing from the spirit and scope of the utility model, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the claims and their equivalents.
