Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
The first embodiment is as follows:
as shown in fig. 1-2, an automatic exhaust dropping funnel comprises a dropping funnel body 1, an exhaust valve 2, an exhaust valve protective cap 3 and a dropping funnel cover 4, wherein the exhaust valve 2 is located at the bottom of the dropping funnel body 1, and the dropping funnel cover 4 is located at the top of the dropping funnel body 1.
Be equipped with a first exhaust groove that extends along vertical direction at least on the side of exhaust post 5, the periphery of discharge valve 2 is located to discharge valve helmet 3 bonding cover, and has the exhaust clearance between the inner wall of discharge valve helmet 3 and the outer wall of exhaust post 5, be equipped with a second exhaust groove 7 that extends along vertical direction at least on the lateral wall of discharge valve helmet 3. Meanwhile, the first exhaust grooves and the second exhaust grooves 7 are arranged in a staggered mode, and the width of the second exhaust grooves 7 is larger than that of the first exhaust grooves. In this embodiment, the width of first exhaust groove is 0.30-0.70mm, the width of second exhaust groove 7 is 1.70mm, the quantity of first exhaust groove and second exhaust groove 7 equals, and both are three and equipartition.
