Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 It is a structural schematic diagram of a funnel with a normal curved surface in the present invention, which is composed of a funnel body 1 with a normal curved surface and an outlet conduit 2 connected. The outlet conduit 2 is a tapered pipe with a wide top and a narrow bottom. The funnel body 1 is a bivariate normal surface, and the shape of the funnel body satisfies the bivariate normal surface equation established by rotating the normal distribution curve along the fluid depth downwards as the positive direction of the symmetric axis z-axis:

[0012]

[0013] Among them, x is the first variable in the horizontal direction, y is the second variable in the horizontal direction, σ is the standard deviation in the x and y directions, and k is the correction coefficient.

[0014] Based on this, the entrance of the fluid passing through th...

Abstract

The invention discloses a normal curved surface funnel and belongs to the field of daily tools. The normal curved surface funnel is formed by connecting a normal curved surface funnel body with an outlet guide pipe; the funnel body is a bivariate normal curved surface; the appearance of the funnel body meets a bivariate normal curved surface equation which is established by taking a fluid depth downward direction as a forward direction of symmetry axis z to rotate a normal distribution curve; and a fluid outlet is a conical pipeline and is of a structure with a wide upper part and a narrow lower part. The normal curved surface funnel has the advantages that smoothness characteristics are everywhere, the design is simple, the resistance of fluid passing through the funnel is small, the funnel can be effectively prevented from being blocked when the fluid, powder and granules are guided, and the guide efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of daily tools, and in particular relates to a funnel with a normal curved surface. Background technique [0002] Funnel or funnel-shaped devices are widely used in production and life, and can be used to inject liquid, powder and granular objects into containers or pipes with smaller inlets. The current common funnel is mainly composed of two parts: a conical funnel body and an outlet conduit. The design of the funnel body usually only considers the volume and ignores the guiding efficiency. Therefore, during the actual use of the funnel, blockage and overflow often occur, causing inconvenience in use. Contents of the invention [0003] The purpose of the present invention is to provide a funnel with normal curved surface aiming at the problems of the prior art. [0004] The purpose of the present invention adopts the following technical solutions: a normal curved surface funnel, which is composed of a ...
