Description

Technical Field

[0001] The present invention belongs to the technical field related to beverage preparation equipment, and in particular relates to a capsule brewing device. Background Art

[0002] Devices for preparing beverages by injecting a pressurized fluid into a capsule are known, in particular in the field of making coffee or coffee-like beverages. In addition, other substances such as chocolate or dairy products can also be extracted or dissolved to form a beverage. The advantages of such systems are in particular the preservation and freshness of the ingredients and the ease of handling when preparing the beverage.

[0003] The method for preparing a beverage using such an apparatus is basically as follows. Usually, a sealed capsule is first inserted into a brewing chamber of the beverage preparation apparatus. Then, a water injection device, such as a needle connected to the liquid supply of the apparatus and extending into the brewing chamber, is directed through or pierced through the surface of the capsule to inject hot or cold liquid, thereby causing the liquid to interact with the ingredients in the capsule. The liquid beverage resulting from this interaction is then discharged through the dispensing face of the capsule. For example, the dispensing face is opened due to the internal pressure generated in the capsule by the injection of the liquid.

[0004] It will be appreciated that the interaction between the ingredients within the capsule and the liquid may be, for example, dissolving, extracting, brewing or any other interaction for preparing a beverage from the ingredients provided within the capsule.

[0005] At present, the existing capsule brewing device uses a drawer-type capsule chamber assembly to place capsules and prepare beverages. When the capsule chamber assembly is taken out from the housing of the capsule brewing device, the handle on the capsule holder assembly can still be driven downward, and the handle driven downward drives the hydraulic plate to move downward. Since the capsule chamber assembly is taken out, the needles on the hydraulic plate are exposed.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1 , Figure 2 A capsule brewing device provided in one embodiment of the present invention comprises a housing 10, a capsule holder assembly 20 and a capsule cavity assembly 30 arranged on the housing 10, wherein the capsule cavity assembly 30 is detachably connected to the housing 10, so that when the capsule brewing device is in use, the capsule can be put in and taken out by disassembling and assembling the capsule cavity assembly 30 relative to the housing 10.

[0030] The capsule holder assembly 20 includes a handle 21, a transmission structure 22 and a hydraulic plate 23. The handle 21 is connected to the hydraulic plate 23 through the transmission structure 22. When the handle 21 is manually driven to flip up and close down relative to the housing 10, the handle 21 can drive the hydraulic plate 23 to reciprocate up and down relative to the capsule chamber assembly 30 through the transmission structure 22. When the hydraulic plate 23 moves downward, the puncture needle (not shown) on the hydraulic plate 23 partially extends outward, thereby realizing the capsule holder assembly 20 to puncture the capsule placed on the capsule chamber assembly 30.

[0031] In this embodiment, a puncture needle stopping assembly 40 is provided on the housing 10, and when the capsule chamber assembly 30 is separated from the housing 10, the puncture needle stopping assembly 40 can limit the puncture needles on the hydraulic plate 23 from extending outward. The puncture needle stopping assembly 40 is applied to the capsule brewing device, specifically by limiting the downward movement of the hydraulic plate 23, so as to limit the puncture needles on the hydraulic plate 23 from extending outward.

[0032] The number of the puncture needle stop assembly 40 is set to two, and the two puncture needle stop assemblies 40 are separated on both sides of the hydraulic plate 23 to limit the downward movement of the hydraulic plate 23, thereby improving the stability of the puncture needle stop assembly 40 in limiting the downward movement of the hydraulic plate 23. It can be understood that the number of the puncture needle stop assembly 40 is not limited to that shown in the figure, and those skilled in the art can set the number of the puncture needle stop assembly 40 to one, three, or even more according to needs.

[0033] Please also read Figure 3 The puncture needle stop assembly 40 of this embodiment includes a stop plate 41, a roller 42, an elastic member 43, a pressure plate 44 and a mounting seat 45; the elastic member 43 can push the stop plate 41 to be partially inserted into the hydraulic plate 23, so that the stop plate 41 blocks the hydraulic plate 23 from moving downward, so that the puncture needle stop assembly 40 limits the puncture needles on the hydraulic plate 23 from extending outward. The elastic member 43 is preferably a spring, and the spring is pre-compressed and assembled between the stop plate 41 and the mounting seat 45.

[0034] Correspondingly, a limit baffle 231 is provided on the hydraulic plate 23, and when the stop plate 41 is partially inserted into the hydraulic plate 23, the portion of the stop plate 41 inserted into the hydraulic plate 23 is arranged at the gap position below the limit baffle 231, and the stop plate 41 is used to block the limit baffle 231 on the hydraulic plate 23 from moving downward, so that the stop plate 41 limits the downward movement of the hydraulic plate 23, thereby limiting the outward extension of the needles on the hydraulic plate 23. It can be understood that the hydraulic plate 23 is used to cooperate with the stop plate 41 to limit the downward movement of the hydraulic plate 23 is not limited to that shown in the figure, and those skilled in the art can set other structures on the hydraulic plate 23 according to needs, or directly open a gap on the hydraulic plate 23 to achieve it.

[0035] Among them, the roller 42 is arranged on the housing 10 and can move up and down relative to the housing 10; the roller 42 and the stop plate 41 can be abutted and matched through their respective inclined surfaces, and the capsule cavity assembly 30 can drive the roller 42 to abut and match with the stop plate 41.

[0036] Specifically, when the capsule chamber assembly 30 is assembled to the housing 10, the capsule chamber assembly 30 drives the roller 42 to move upward relative to the housing 10, so that the roller 42 abuts against the stop plate 41, and pushes the stop plate 41 to compress the elastic member 43 through the inclined surface cooperation between the roller 42 and the stop plate 41, that is, when the capsule chamber assembly 30 is assembled to the housing 10, the stop plate 41 is arranged away from the hydraulic plate 23. When the capsule chamber assembly 30 is separated from the housing 10, the roller 42 moves downward relative to the housing 10 under the push of the stop plate 41 and the action of gravity, so that the roller 42 is separated from the stop plate 41, and at the same time, the elastic member 43 pushes the stop plate 41 to be inserted into the hydraulic plate 23 due to the restoration of its own elastic deformation, so that the stop plate 41 limits the downward movement of the hydraulic plate 23. That is to say, the puncture needle stopping assembly 40 of the present embodiment can control whether the stopping plate 41 restricts the downward movement of the hydraulic plate 23 through the cooperation between the roller 42 and the capsule chamber assembly 30 .

[0037] Please also read Figure 7 The roller 42 includes a cam portion 421, a driving portion 422 disposed on the cam portion 421 and used to abut against the stop plate 41, and the driving portion 422 has an inclined surface that can abut against the stop plate 41, wherein a limiting convex column 423 is disposed on the driving portion 422, and the limiting convex column 423 is disposed on a side of the driving portion 422 away from the stop plate 41. Please refer to Figure 4 A limited support 11 is provided on the housing 10, and the roller 42 is provided on the limited support 11 of the housing 10 through the limited boss 423, so as to realize the assembly of the roller 42 on the housing 10 and realize the up and down movement of the roller 42 relative to the housing 10.

[0038] The pressing plate 44 is disposed on the top surface of the stop plate 41 and is fixedly connected relative to the housing 10, and is used to limit the stop plate 41 on the housing 10. When the stop plate 41 is driven by the inclined surface of the roller 42, the stop plate 41 can only move close to the housing 10, thereby ensuring that when the stop plate 41 is driven by the roller 42, the stop plate 41 will not be separated from the housing 10.

[0039] In this embodiment, the pressing plate 44 is fixedly connected to the housing 10 by screws (not shown), and the housing 10 is provided with two connecting posts 12, and the pressing plate 44 is arranged on the two connecting posts 12 and connected and fixed by screws. It can be understood that the connection and fixation between the pressing plate 44 and the two connecting posts 12 on the housing 10 is not limited to screws, and those skilled in the art can connect and fix the pressing plate 44 and the two connecting posts 12 by glue according to needs, or the two connecting posts 12 and the pressing plate 44 can be set as an integrated structure, and the two connecting posts 12 are fixed to the housing 10 by screws or glue.

[0040] Please also read Figure 5 , Figure 6 , the stop plate 41 is used to be inserted into the hydraulic plate 23 and limit the downward movement of the hydraulic plate 23. In this embodiment, the stop plate 41 includes a stop plate body 411, a stop bar 412 and a limit arc plate 413 provided on the stop plate body 411, wherein the stop plate body 411 can be abutted and matched with the driving part 422 of the roller 42 through an inclined surface, and the stop bar 412 can be inserted into the hydraulic plate 23 to limit the downward movement of the hydraulic plate 23; the limit arc plate 413 is used to limit the position of the elastic member 43, and is used to ensure that the elastic member 43 always abuts against the stop plate body 411 of the stop plate 41, so that the elastic member 43 provides the stop plate body 411 with a force in the direction of the hydraulic plate 23.

[0041] The stopper arc plate 413 is provided with a baffle plate 414 on the side away from the baffle bar 412, and the baffle bar 412 and the baffle plate 414 are respectively used to abut against the pressure plate 44, so as to achieve abutment between the pressure plate 44 and the stop plate 41. That is to say, the pressure plate 44 on the needle stop assembly 40 of this embodiment limits the stop plate 41 on the housing 10 by abutting against the baffle bar 412 and the baffle plate 414 on the stop plate 41. Since the baffle bar 412 and the baffle plate 414 are separated on both sides of the stop plate body 411, on the basis of ensuring that the pressure plate 44 limits the stop plate 41 on the housing 10, the elastic member 43 drives the stop plate 41 to move along the axial direction of the elastic member 43.

[0042] Furthermore, the stop plate body 411 is provided with a protrusion 415 inside the limiting arc plate 413, and when the elastic member 43 and the stop plate 41 cooperate with each other, the elastic member 43 can be sleeved on the protrusion 415 and limited by the limiting arc plate 413, so as to ensure that when the elastic member 43 and the stop plate 41 are abutted and matched, the two are not offset, and it also facilitates the mutual assembly between the elastic member 43 and the stop plate 41.

[0043] The mounting seat 45 is fixedly arranged on the casing 10, and is used to abut and cooperate with the elastic member 43, so that when the roller 42 loses the force acting on the stop plate 41, the elastic member 43 can push the baffle 412 on the stop plate 41 to be inserted into the position below the upper limit baffle 231 of the hydraulic plate 23, so as to limit the downward movement of the hydraulic plate 23.

[0044] In summary, the capsule brewing device provided by the present invention has a reasonable structural setting of the puncture needle stop assembly, so that when the capsule chamber assembly on the capsule brewing device is separated from the casing, the puncture needle stop assembly can be used to limit the puncture needle on the hydraulic plate to extend outward, thereby avoiding injuries and damage to the puncture needle caused by the exposure of the puncture needle, and further meeting people's needs for the use of the capsule brewing device.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
