The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is done further explain.
Mill beans formula coffee machine as shown in Figure 1; Comprise body (not shown) and coffee bean lapping device (not shown); The coffee bean lapping device is installed on the top of installing plate 1 in the body; Installing plate 1 is provided with coffee powder outlet 12, and coffee powder outlet 12 is connected through the coffee powder passage with the coffee bean lapping device.The below of coffee powder outlet 12 is provided with the funnel assemblies (not shown), and this funnel assemblies is in order to holding the coffee powder that flows out from coffee powder outlet 12, and at this with coffee powder and hot water mixing, brew into coffee liquid.
Extremely shown in Figure 7 like Fig. 2; In order to prevent that the steam in the funnel from rushing in the coffee powder passage, between outlet 12 of the utility model coffee powder and funnel assemblies, also be provided with the steam seal device, this steam seal device comprises and is installed on last potsherd 3 and the following potsherd 5 that coffee powder exports the no gap contact of 12 belows; Though have pottery to limit in the title of last potsherd 3 and following potsherd 5; But be not limited to ceramic material, nothing but any surface finish because of ceramic material, good sealing effect; Other materials with congruence property also are fit to the utility model fully, like metal material.Be respectively equipped with on last potsherd 3 and the following potsherd 5 with coffee powder and export corresponding potsherd through hole 32 and the following potsherd through hole 52 gone up of 12 shapes; Described herein is not relatively refers to go up potsherd through hole 32 and following potsherd through hole 52 and coffee powder and exports 12 in full accordly, can overlap and makes coffee powder can fall into funnel assemblies as long as through hole and coffee powder export 12.Last potsherd 3 is installed on the installing plate 1 through last potsherd axis hole 31, and to be retained to a rare part overlapping with coffee powder outlet 12 all the time for last potsherd through hole 32.Following potsherd 5 is installed on the installing plate 1 through following potsherd axis hole 51; The outer rim of following potsherd 5 is provided with the gear teeth; With travelling gear 8 engagements that are installed on 4 of the synchronous motors; Said synchronous motor 4 is fixedly installed on the installing plate 1, and synchronous motor 4 drives potsherd 5 rotations down through travelling gear 8, makes down potsherd 5 connections or closes the passage between coffee powder outlet 12 and the funnel assemblies.In order further to strengthen sealing effectiveness, between travelling gear 8 and installing plate 1, also be provided with Simmer ring 7.In addition, come off, on the installing plate 1 of present embodiment cover plate 6 is installed also, but coffee powder outlet 12 can not be blocked in the position of cover plate 6 in order to prevent down potsherd 5 and travelling gear 8.
In order further to limit the rotation amplitude of potsherd 5 down; Make down potsherd 5 location more accurate; Also be provided with block 9 on the installing plate 1 in the present embodiment, block 9 and 8 coaxial connections of travelling gear, block 9 is provided with nose bar 91; Nose bar 91 rotates with block 9; Simultaneously, can to stop first limited block 11 that nose bar 9 moves forward and second limited block, 13, the first limited blocks 11 and the relative position of second limited block 13 on installing plate 1 mainly be that size by coffee powder outlet 12 and following potsherd through hole 52 determines also being provided with on the installing plate 1; Because appeal the main effect of two limited blocks is to limit the rotation amplitude of travelling gear 8 and further limit the rotation amplitude of potsherd 5 down through the space that limits nose bar 91; Therefore, as long as the relative position of first limited block 11 and second limited block 13 can make down potsherd 5 in its rotation amplitude scope, realize being communicated with or closing the purpose of coffee powder outlet 12, and the technology that the technical staff knew that this point is the present technique field.In addition, block 9 shapes in the present embodiment are not limited to scope shown in Figure 6, and the shape of block 9 mainly is to limit according to its function, as long as can realize limiting the purpose of travelling gear rotation amplitude.
The operation principle of present embodiment is: synchronous motor 4 drives travelling gear 8 and rotates, and potsherd 5 rotates under further driving then, and following potsherd 5 has two operating positions; Instantly potsherd 5 is when primary importance, and it is 12 overlapping that following potsherd through hole 52 and last potsherd through hole 32 and coffee powder export, and the passage between coffee powder outlet 12 and the funnel assemblies is connected; Coffee powder falls into funnel assemblies through coffee powder outlet 12; At this moment, also arrive first operating position with the travelling gear 8 coaxial blocks that are connected 9, the nose bar 91 on the block 9 receives stopping of first limited block 11 just; At this moment, potsherd 5 backwards rotation under synchronous motor 4 beginning backwards rotation and the drive.Along with being rotated further of following potsherd 5; Following potsherd through hole 52 misplaces with last potsherd through hole 32 gradually; Final potsherd down 5 arrives the second place: following potsherd through hole 52 complete and last potsherd through hole 32 dislocation; Promptly descend potsherd 5 that coffee powder outlet 12 is closed fully, thereby prevent that the steam in the coffee basket from getting into the coffee powder passage.When the second place, the nose bar 91 on the block 9 receives stopping of second limited block 13 just, and at this moment, synchronous motor 4 is backwards rotation and drive down potsherd 5 backwards rotation once more once more, makes down potsherd 5 get back to primary importance once more, so back and forth rotation.The synchronous motor 4 automatic reverse running that meets with obstruction is a technology well-known to those skilled in the art, at this not in detailed argumentation.
The above-mentioned rotation amplitude that limits down potsherd 5 through block 9 and limited block only is a kind of specific embodiment that can realize the object of the invention; Under not to the situation that the rotation amplitude of potsherd 5 limits down, also can realize the object of the invention, only descend potsherd 5 when primary importance goes back to primary importance once more, need rotate around the axis a week.In addition, for the structure that makes the steam seal device is simplified more, the following potsherd 5 of the utility model also can directly be connected with the axle of synchronous motor 4.
More than be merely some specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, all unsubstantialities of on the utility model basis, making change the protection domain that all will fall into the utility model.
