Abstract

The invention provides a drainage funnel with an internal filtering structure, which is characterized in that the internal filtering structure is provided with a spiral filtering structure, and the spiral filtering structure comprises a hollow-out spiral surface. The hollow-out type spiral surface is inclined to the bottom of the launching funnel to form a certain angle or is parallel to the bottom of the launching funnel. According to the drainage funnel, the spiral filtering structure is additionally arranged in the drainage funnel, so that residues are prevented from seeping through the drainage funnel and flowing into a drainage pipeline, the drainage funnel is convenient to clean, and the problem of blockage of the drainage funnel and even the drainage pipeline is effectively solved.

Description

Drainage funnel with internal filtering structure

Technical Field

The invention relates to the field of household articles for daily use, in particular to a drainage funnel with an internal filtering structure.

Background

The sewage funnel is indispensable in our daily life, and can prevent the blockage caused by the fact that the waste residues are injected into the sewage pipeline along with running water when we use water in daily life. A launching funnel is generally arranged in the vegetable washing basin. The existing launching funnel is generally a single-layer mesh type which is adapted to the opening of a sewer pipe, and is generally of a U-shaped structure. When the water discharging funnel is used, some fine food residues still pass through the water discharging funnel along with water flow, and the water discharging funnel and even a water discharging pipeline are easily blocked after long-term accumulation. Therefore, the filtering structure and the filtering effect of the launching funnel directly influence the use experience of the launching funnel.

Disclosure of Invention

The invention aims to provide a drainage funnel with an internal filtering structure, which further enhances the filtering function by improving the internal structure, avoids the problem that food residues flow into a drainage pipeline, has better filtering residue effect, more fully prevents the food residues from entering the drainage funnel and the drainage pipeline and prevents blockage.

The key point of the drain funnel with the internal filtering structure is that the internal filtering structure is provided with a spiral filtering structure, and the spiral filtering structure comprises a hollow-out spiral surface. The hollow-out type spiral surface is inclined to the bottom of the launching funnel to form a certain angle or is parallel to the bottom of the launching funnel. The hollow-out type can be directly set into a net surface. The hollow helicoid is equivalent to that a layer of filter mesh is added in the inner part of the launching funnel, so that the effect of filter residue is better and the anti-blocking function is enhanced while water flow is not influenced.

Further, the spiral filtering structure is a slide type spiral structure or a staggered spiral structure. The spiral structure can form a complete second filtering layer corresponding to the bottom of the launching funnel, and meanwhile, filtered residues are poured out conveniently when the launching funnel is cleaned.

Further, slide formula helical structure still includes the support column, fretwork formula helicoid encircles the support column from top to bottom inclines to drive to launching hopper's bottom.

Further, the support column is vertically arranged along the bottom midpoint of the launching funnel.

Furthermore, the hollow-out type spiral surface of the staggered spiral structure is a plurality of spiral stepped semi-circular surfaces or circular arc surfaces. The filter screens with a plurality of semicircular surfaces or arc surfaces are arranged in a spiral stepped mode from top to bottom, each semicircular surface or arc surface forms partial filtration on the layer surface, and a plurality of filter layers which are arranged in an up-and-down staggered mode can form a complete second filter layer surface corresponding to the bottom of the launching funnel.

In order to facilitate cleaning after filtering residues, the staggered spiral structure can be arranged into two semicircular surfaces which are staggered up and down or three circular arc surfaces which are staggered up and down.

Further, the sizes of the semicircular surfaces or the circular arc surfaces are consistent.

According to the drainage funnel, the spiral filtering structure is additionally arranged in the drainage funnel, so that residues are prevented from seeping through the drainage funnel and flowing into a drainage pipeline, the drainage funnel is convenient to clean, and the drainage funnel and even the drainage pipeline are more effectively prevented from being blocked.

Drawings

Fig. 2 is a perspective view of the internal structure of embodiment 2 of the present invention.

The figures are numbered:

1. a launching funnel; 2. a hollow-out type helicoid; 3. and (4) a support column.

Detailed Description

The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.

Example 1:

as shown in fig. 1, the key point of the drain funnel 1 with the internal filtering structure of the present invention is that the internal filtering structure is provided with a spiral filtering structure, the spiral filtering structure is a slide-type spiral structure, and comprises a hollow-out spiral surface 2 and a supporting column 3, the hollow-out spiral surface 2 surrounds the supporting column 3 and is obliquely driven to the bottom of the drain funnel 1 from top to bottom, and the supporting column 3 is vertically arranged along the bottom midpoint of the drain funnel 1.

Slide formula helical structure's fretwork formula helicoid 2 inclines to the bottom of launching funnel 1 and becomes certain angle, and the fretwork formula can directly set to the wire side, and then fretwork formula helicoid 2 has set up the one deck in launching funnel 1's inside in other words and has filtered the mesh, when not influencing rivers, the effect of filter residue is better, prevents stifled function reinforcing. Meanwhile, the filtered residues are convenient to dump out when the drainage funnel 1 is cleaned.

Example 2:

as shown in fig. 2, the key point of the drain funnel 1 with internal filtering structure of the present invention is that its internal has a spiral filtering structure, which is a staggered spiral structure and includes a hollowed-out spiral surface 2. The hollow-out type helicoids 2 of the staggered spiral structure are three arc surfaces which are staggered up and down and are in a spiral step type. Each arc surface is parallel to the bottom of the launching funnel 1.

In the above, the up-down staggering means that the circle center parts of the arc surfaces are partially overlapped with the edges of the projection in the longitudinal direction. The three circular arc surface filter screen sets up with the cascaded from top to bottom of spiral, and every circular arc surface forms the part on its aspect and filters, and the crisscross setting can form and filter the aspect with the corresponding complete second in launching funnel 1 bottom about three, when not influencing rivers, the effect of filter residue is better, prevents stifled function reinforcing.

In the specific design, the hollowed-out spiral surface 2 can also be arranged into two semicircular surfaces which are staggered up and down.

The basic idea and the basic principle of the invention have been explained above by way of an introduction to the embodiments listed. The invention is in no way limited to the embodiments listed above. All equivalent changes, improvements, deliberate deteriorations and the like based on the technical scheme of the invention shall fall within the protection scope of the invention.
