The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As Figure 1-5, coffee machine foam-making apparatus, comprise high pressure funnel 4, filter cup, arranges bushing 5 in filter cup, pressurized hole 6 is established in filter cup bottom, filter cup is placed in high pressure funnel inner chamber top, between described pressurized hole and high pressure funnel intracavity bottom, be provided with coffee mouth 1 and spout of funnel 3, described coffee mouth 1 is the plate-like of back-off, in the bottom surface of coffee mouth, is fixedly mounted with filter screen compressing tablet 2; The geometric center of coffee mouth is provided with centre bore 10, along centre bore edge to the location ring body 12 of downward-extension symmetry, centre bore both sides are provided with projection 11, thereby the below hollow out of described breakthrough 11 forms inlet channel 17, inlet channel 17 and described location ring body 12 the mixed air cavity of the centre bore that surrounds be connected, what the cylindrical portion symmetry of described coffee mouth 1 had a rectangle confluxes mouthfuls 13; On described filter screen compressing tablet 2, be provided with filter screen groove 21, place the filter net sheet 7 of three in filter screen groove, it is interior by described filter net sheet 7 pressure holdings that the location ring body 12 of described coffee mouth extend into filter screen groove 21.In order to form, enrich fine and smooth coffee foam, there is sufficient air, pressurized hole 6 to the suitable distance of filter net sheet 7 is very important, the present invention is fixed on the bottom surface of coffee mouth 1 by filter screen compressing tablet 2, and, the location ring body 12 of coffee mouth extend into, filter screen groove 21 is interior keeps air unimpeded filter net sheet 7 pressure holdings, design inlet channel, more than design makes after the centre bore of coffee mouth 1, can form abundant and fine and smooth coffee foam from pressurized hole high pressure coffee liquid out, thereby has met consumer's high-quality requirement brewed to foam coffee.
Referring to Fig. 2-4, the both sides of the compressing tablet through hole 22 of filter screen compressing tablet 2 arrange installing hole 23, correspondingly, on the bottom surface of coffee mouth 1, correspondence arranges compression leg 18, installing hole 23 is positioned on erecting bed 24, erecting bed 24 is fan-shaped filter screen groove 21 both sides that are symmetrically distributed in, and installs, at the fan-shaped operating desk 25 of the outside Widening Design in the bottom of erecting bed 24 for the ease of workman.Referring to Fig. 3, bottom surface from coffee mouth 1, inlet channel 17 is a pair of fan-shaped heavy chambeies, heavy chamber is at the central hole opening of coffee mouth 1, because coffee mouth is plate-like, its cylindrical is to have the mouth that confluxes on inclined-plane and cylindrical, therefore, air enters in coffee mouth from the mouth that confluxes, and through inlet channel 17, enters into the mixed air cavity of centre bore.Because the diameter of centre bore is little, in order to be formed with enough large inlet channel, inlet channel is designed to fan-shaped, thereby increase the internal volume of inlet channel.In inlet channel, be also provided with reinforcement 16, to support better the intensity of inlet channel, simultaneously can make coffee mouth 1 be easier to injection molding, guaranteed the processing quality of inlet channel.Conflux mouthfuls 13 for rectangle, it also for collect from pressurized hole 6 out, be injected in the coffee liquid of coffee nozzle surface, make to fail the cylindrical inclined-plane of the liquid runs down coffee mouth by centre bore to be pooled to and to conflux on mouth.
On the cylindrical of coffee mouth 1, be also provided with draw-in groove 14, correspondingly, arrange card article 31 is installed on the arc diapire of spout of funnel 3, coffee mouth 1 is fixed on spout of funnel 3 by draw-in groove 14.The diapire of spout of funnel 3 is provided with opening 37, and opening below arranges shunting water channel 32, at shunting water channel 32 two ends, connects respectively drain pipe 33, makes coffee liquid shunting fluid.On the arc diapire of spout of funnel 3 along diapire around the contour waterwall 36 that arranges of opening 37, the middle part of waterwall 36 is circular, middle separated time both sides at spout of funnel are provided with inlet 35, inlet 35 on waterwall 36 makes to enter into coffee liquid in spout of funnel and can be pooled to inlet 35 and enter in shunting water channel 32 from the coffee mouth mouth that confluxes, and coffee liquid can be assigned on two drain pipes 33 more equably.On the diapire of spout of funnel 3, be also provided with erection column 34, erection column is provided with through hole.
Coffee mouth 1, filter screen compressing tablet 2 are working of plastics with spout of funnel 3.The connection rib 15 that arc is set between the fan-shaped projection 11 of two symmetries of coffee mouth 1, both are contour settings, after installation, connect rib 15 near pressurized hole 6 peripheries of filter cup bottom, and coffee liquid is entered in the centre bore of coffee mouth 1 substantially.The bottom of high pressure funnel 4 is provided with effluent trough and a pair of apopore, suitable with shunting water channel 32 and the drain pipe 33 of spout of funnel 3, makes the shunting water channel 32 of spout of funnel 3 and drain pipe 33 can coordinate the bottom that is inserted into high pressure funnel 4.
Coffee machine foam-making apparatus of the present invention is simple in structure, production cost is low, first pressure coffee liquid filters through bushing 5, filtering coffee grounds wherein, then, on the filter net sheet 7 making at stainless steel through pressurized hole 6 high-pressure injections, by mixing with air, produce a large amount of foams, after the splitter box shunting of spout of funnel 3, from drain pipe 33, leave coffee machine equably again, enter in coffee cup.The coffee foam of coffee machine foam-making apparatus made of the present invention is abundant fine and smooth, and mouthfeel is very good.
The foregoing is only preferred embodiment of the present invention; and be not used in restriction of the present invention; all any modifications of doing within the spirit and principles in the present invention, be equal to the improvement of replacing and doing without creative work etc., within protection scope of the present invention all should be included in.
