Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 4, the novel efficient detachable funnel of the present invention comprises an upper body, a lower body disposed below the upper body, a filter disc 3, and a fixing clip 4. The upper body is a first vertical tube 102 with a first skirt 101 at the lower end, and the lower body comprises an inverted cone-shaped tube 202 with a second skirt 201 at the upper end and a second vertical tube 203 extending downwards, wherein the first skirt 101 and the second skirt 201 can completely coincide. A filter disc 3 for placing filter materials is arranged between the liquid outlet of the upper part body and the inlet of the lower part body. Still the centre gripping is connected with fixation clamp 4 between the upper portion body and the lower part body, can be fixed the upper portion body with the combination of lower part body under the effect of fixation clamp 4 promptly, and the internal filtrations of upper portion filter the backward down-flow and flow into back taper body 202 through the filtering material on filtering disc 3 in, flow into to holding the container of filtrating through the vertical body 203 of second again to accomplish filtering operation.

The upper body and the lower body are made of glass, ceramic, metal or plastic, and are simple to manufacture, low in cost, very durable and high in practicability. In order to improve the connection sealing performance between the liquid outlet of the upper part body and the inflow inlet of the lower part body, the contact surfaces of the upper part body and the lower part body are both provided with frosted surfaces. The operation is simple and the sealing performance is good.

The inflow opening of the lower body has a ring-shaped support plate 5 therein, and the filter disc 3 is mounted in a filter disc mounting opening 6 in the ring-shaped support plate 5 in an embedded manner. Wherein the filter disc 3 can be detached, and the diameter of the filter disc 3 is smaller than the inner diameter of the upper part. The filter disc 3 can meet the filter requirements of filter objects with different characteristics only by replacing the filter disc 3 under the condition of not replacing the funnel, the filter disc 3 is convenient to install and replace, and the filter disc 3 is convenient to clean at the same time.

The filtering disc 3 is a disc with holes for placing filtering materials, the filtering materials are placed between the upper part body and the lower part body, the diameter of each filtering material is larger than the inner diameter of the upper part body, the filtering materials are favorably and quickly padded on the filtering disc 3, and meanwhile the filtering materials are conveniently transferred. Wherein the filter disc 3 can be a sand core, a perforated plate or other forms of filter layers. Wherein the perforated plate in the filter disc 3 is made of ceramics, glass, plastics and metal; other forms of filter layers in the filter disc 3 are metal meshes, plastic meshes, gauze meshes or other net structures. The reason is that the filter is simple to manufacture, low in cost, very durable, suitable for enterprise production and obvious in filtering effect.

The periphery of the filtering disc 3 is provided with a closed rubber ring. When the filtering disc 3 is installed on the annular supporting plate 5 in an embedded mode, the sealed rubber rings on the periphery of the filtering disc can be completely attached to the inner wall of the lower body, so that the purpose of sealing the lower body is achieved, liquid leakage can be avoided, and the filtering effect is improved.

The fixing clip 4 is a metal or plastic clip that fixes the upper body and the lower body in combination. When the first skirt edge 101 of the upper body and the second skirt edge 201 of the lower body are completely overlapped, the first skirt edge 101 and the second skirt edge 201 can be clamped by the fixing clamp 4, so that the upper body and the lower body are fixed in combination.

The upper surface of the second skirt edge 201 of the lower part body is provided with a placing groove (not shown in the figure), the placing groove is of a circular structure, the filtering material is placed on the filtering disc and extends and is laid in the placing groove, and the lower surface of the first skirt edge 101 of the upper part body is provided with a protrusion (not shown in the figure) which vertically extends downwards. When the first skirt edge 101 of the upper body and the second skirt edge 201 of the lower body form an integral structure under the action of the fixing clamp 44, the protrusions and the placing grooves are in inserted fit to fix the filtering material.

The fixing clamp 4 comprises a fixing clamping arm 401 integrally arranged on the upper body and a movable clamping arm 402 hinged with the fixing clamping arm 401, and an elastic part 403 is connected between the movable clamping arm 402 and the fixing clamping arm 401. The elastic member 403 is a torsion spring, and the fixed clip arm 401 and the movable clip arm 402 are abutted against each other under the action of the torsion spring. On fixed arm lock 401 an organic whole was arranged in the first shirt rim department 101 of the upper portion body, fixed arm lock 401 all inclined downwards with activity arm lock 402 and is set up, and the inclination of activity arm lock 402 is greater than the inclination of fixed arm lock 401 to operating personnel separates fixed arm lock 401 and activity arm lock 402. In order to facilitate the operator to hold the fixing clip arm 401, a recess 404 for the operator to press with his thumb is formed on the fixing clip arm 401.

The utility model relates to an ingenious, first shirt rim 101 and second shirt rim 201 are cliied to fixation clamp 4 and make upper portion body and lower part body combination fixed. Filter disc 3 and install in annular support plate 5 on filter disc installing port 6 through the form of inlaying, wherein filter disc 3 can dismantle for under the condition of not changing the funnel, only need to change filter disc 3 and just can satisfy the filtration requirement of different characteristic filter, the installation of being convenient for filter disc 3 is changed, also conveniently washs filter disc 3 simultaneously. In addition, the filtering material on the filtering disc 3 is fixed through the fixing clamp 4, so that the filtering effect is guaranteed, meanwhile, the filtering material such as the filtering paper can be quickly filled in the filtering disc 3, the operation of a user is convenient, the applicability is wide, and the filtering effect is good.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
