Abstract
The utility model relates to a liquid leak hole structure of a pressure coffee machine filtering device. The structure comprises a filtering body; multiple liquid leak holes are arranged on the filtering body; and a lead angle is arranged on each of an upper orifice and a lower orifice of each liquid leak hole respectively, or a lead angle is arranged on the upper orifice of each liquid leak hole. The liquid leak hole structure provided by the utility model has a simple structure and a good effect.
Description
[technical field]
The utility model relates to a kind of pressure coffee machine filter, relates to specifically the leaking hole structure of pressure coffee machine filter.
[background technology]
The coffee place that goes out of general pressure coffee machine all is provided with the filter of infusing coffee, and this coffee filtering device will stamp out one or more liquid-leaking nozzles, and the aperture of liquid-leaking nozzle is generally the 0.1-0.8 millimeter, and the shape of this filter is generally cup-shaped and sheet.By this filter, under certain pressure and temperature, effectively extract the beneficiating ingredient in the coffee, the coffee delicate mouthfeel, the fragrant odour that filter out like this.
But, as shown in figure 10, because the upper and lower aperture 7 in the hole of prior art all is wedge angle, sometimes also have the burr that is difficult for removal, the not lead angle of rounding off.Existing liquid-leaking nozzle generally is comprised of two different through holes, owing to varying in size of these two holes, therefore a platform 8 can be left in the junction of these two through holes.When cooking coffee, coffee liquid flows out and to have some setbacks, and affect the quality of coffee, and spent coffee easily remains in the liquid-leaking nozzle sharp corner with the hole inner platform, and easy cleaning not affects service life of quality of coffee and filter.
The utility model is being made in such cases.
[utility model content]
The utility model purpose is to have overcome the deficiencies in the prior art, and a kind of simple in structure, effective leaking hole structure is provided.
The utility model is achieved through the following technical solutions:
The leaking hole structure of pressure coffee machine filter, it is characterized in that including filtering bodies 1, be arranged with a plurality of liquid-leaking nozzles 2 in filtering bodies 1, be equipped with lead angle 3 or be provided with lead angle 3 in the upper aperture 4 of each liquid-leaking nozzle 2 in upper aperture 4 and the lower aperture 5 of each liquid-leaking nozzle 2.
The leaking hole structure of aforesaid pressure coffee machine filter is characterized in that described lead angle 3 is arc angle.
The leaking hole structure of aforesaid pressure coffee machine filter is characterized in that described lead angle 3 is the circular arc angle.
The leaking hole structure of aforesaid pressure coffee machine filter is characterized in that described liquid-leaking nozzle 2 includes the cylindrical hole 21 that places top and round taper hole or the polygon bellmouth 22 that places the bottom; Described cylindrical hole 21 is connected the 22 direct transition of polygon bellmouth and is connected with round taper hole.
The leaking hole structure of aforesaid pressure coffee machine filter is characterized in that the radius 0.01-0.5mm of described arc chord angle.
Compared with prior art, the utility model has the following advantages:
Small structure of the present utility model is all to establish lead angle or be provided with lead angle in upper aperture in upper aperture and the lower aperture of liquid-leaking nozzle, and lead angle is circular arc, and arc radius is between 0.01-0.5mm, and the platform in the cancellation liquid-leaking nozzle makes this new liquid-leaking nozzle increase round and smooth degree.When cooking coffee, coffee liquid is more smooth and easy when flowing out, and spent coffee is not easy to remain in the aperture, easily cleans, and guarantees the quality of coffee, prolongs the service life of this filter.

[specific embodiment]
The leaking hole structure of pressure coffee machine filter, it is arranged on the coffee machine, and it includes filtering bodies 1, is arranged with a plurality of liquid-leaking nozzles 2 in filtering bodies 1.Be equipped with lead angle 3 or go up aperture 4 therein in the upper aperture 4 of each liquid-leaking nozzle 2 and lower aperture 5 and be provided with lead angle 3.Like this, be provided with lead angle 3 and will make liquid-leaking nozzle increase round and smooth degree, when cooking coffee, coffee liquid is more smooth and easy when flowing out, and spent coffee is not easy to remain in the aperture, easily cleans, and the coffee quality is good.Certainly, lead angle is arranged on the upper aperture 4 of liquid-leaking nozzle 2 and the effect in lower aperture 5 is best.And the lead angle that is arranged on aperture 4 can be the same with the radian that is arranged on lower aperture 5 lead angles, also can be different, can be according to the needs setting that realizes.In the present embodiment, in the scope of the radius 0.01-0.5mm of described arc chord angle.
As the optimal way of the present embodiment, described lead angle 3 is arc angle.
As the optimal way of the present embodiment, described lead angle 3 is round angle.
As the optimal way of the present embodiment, described liquid-leaking nozzle 2 includes the cylindrical hole 21 that places top and round taper hole or the polygon bellmouth 22 that places the bottom.Be illustrated in figure 2 as round taper hole; Figure 5 shows that polygon bellmouth.Described cylindrical hole 21 is connected the 22 direct transition of polygon bellmouth and connects with round taper hole, do not had the platform 8 between two holes.When cooking coffee, coffee liquid is more smooth and easy when flowing out like this, and spent coffee is not easy to remain in the aperture, easily cleans, and guarantees the quality of coffee, prolongs the service life of this filter.
In addition, this filtering bodies 1 can be arranged on the different filters, on the filter cup that can be arranged on individual layer, can also be arranged on double-deck filter cup, also can be arranged on the filter, etc.
When filtering bodies was arranged on the filter cup of individual layer, filter cup had generally comprised cup 4, and described filtering bodies 1 is arranged on the bottom of cup 4, the part at the bottom of filtering bodies 1 is glass.As shown in Figure 7.
When filtering bodies was arranged on double-deck filter cup, filter cup had generally comprised cup 5 and a cup end 6, and described filtering bodies 1 is arranged on the bottom of cup 4, and 6 top makes filtering bodies 1 form a filter screen at the bottom of placing glass.As shown in Figure 8.
When filtering bodies was arranged on the filter, filter just formed filtering bodies, and liquid-leaking nozzle is set directly on the filter.As shown in Figure 9.
