Description

Technical Field

[0001] The utility model relates to the technical field of extraction, in particular to a coffee machine extraction device. Background Art

[0002] The extraction device is mainly used to pierce the membrane at the top of the coffee capsule to inject the brewing liquid into the interior, and then the mixed coffee flows out through the outlet at the bottom of the coffee capsule; however, traditional extraction devices usually only have the function of piercing the sealing membrane at the top of the capsule, and lack the function of piercing the sealing membrane at the bottom of the capsule. Some patents pierce the membranes at the top and bottom of the capsule at the same time by setting a longer piercing device, but this method is easy to cause the coffee powder and liquid to flow out through the punctured outlet at the bottom of the capsule without uniform mixing, resulting in poor mixing effect.

[0003] For example, the utility model patent (application number: 201920543211.8) discloses a "capsule beverage extraction device." Its specification discloses that the beverage extraction mechanism includes a vertically arranged central pipe fixed to a first base plate at the bottom of a water storage cup. A seal is inserted at the top of the central pipe, and the bottom end of the water outlet pipe communicates with the central pipe through the seal. The portion of the bottom pipe with a liquid inlet is positioned within the interior chamber of the extraction cup. A plurality of second liquid outlets are formed in the lower portion of the bottom pipe, and the second liquid outlets are positioned below the second base plate. The piston is positioned between the liquid inlet and second liquid outlets. This device extracts beverages by completely piercing the beverage capsule, placing minimal demands on the capsule's shape. Even if the capsule does not meet these requirements, beverage extraction can be achieved by simply opening the capsule and pouring the powder inside into the extraction cup. This device has minimal usage restrictions, is simple in structure, compact in size, and is easy to carry and manufacture. The aforementioned patent serves as evidence of the shortcomings of the prior art.

[0004] Therefore, we have made improvements to this and proposed a coffee machine extraction device. Summary of the Invention

A limiting ring 10 is fixed at the bottom end of the mounting plate 61. The limiting ring 10 is used to fix the capsule and cooperate with the mounting plate 61 to seal the top of the capsule.

[0042] Example 3

[0043] The coffee machine extraction device provided in Example 1 and Example 2 is further optimized, such as Figure 2 、 Figure 4 and Figure 5 As shown, the connecting assembly 7 includes a No. 1 connecting tube 71 fixed to the front end of the mounting plate 61, and the rear end of the No. 1 connecting tube 71 is fixedly connected to the No. 2 connecting tube 72. A needle tube 73 is provided at the bottom end of the mounting plate 61. The needle tube 73 is used to penetrate the sealing membrane at the top of the capsule, and the water flows into the capsule from the end of the needle tube 73 through the No. 1 connecting tube 71 and the No. 2 connecting tube 72 through an external water source. The bottom end of the No. 2 connecting tube 72 passes through the mounting plate 61 and is fixedly connected to the needle tube 73.

[0044] Further, such as Figure 2 and Figure 6As shown, the front end of the No. 1 connecting pipe 71 is connected to the No. 3 connecting pipe 13, and the No. 3 connecting pipe 13 is used to put the external connected water pipe on it to connect the external water pipe. The No. 1 connecting pipe 71 is provided with a reinforcement component 8, and the reinforcement component 8 allows the No. 3 connecting pipe 13 to adapt to and install water pipes of various sizes. The reinforcement component 8 includes a No. 1 connecting ring 81 that is threadedly connected to the outside of the No. 1 connecting pipe 71. The front end of the No. 1 connecting ring 81 is provided with a No. 2 connecting ring 83. Rotating the No. 1 connecting ring 81 in two directions controls the forward and backward movement of the No. 2 connecting ring 83. The top and bottom ends of the No. 1 connecting ring 81 are fixed with a No. 3 connecting plate 82, and the No. 1 connecting ring 81 and the No. 2 connecting ring 83 are connected by the No. 3 connecting plate 82. The No. 3 connecting plate 82 is fixedly connected to the No. 2 connecting ring 83, and the interior of the No. 2 connecting ring 83 is fixed with a mounting ring 84.

[0045] Further, such as Figure 6 and Figure 7 As shown, a No. 2 sealing ring 12 is fixedly provided at the rear end of the mounting ring 84, and a No. 1 sealing ring 11 is fixedly provided at the front end of the No. 3 connecting pipe 13. The No. 1 sealing ring 11 and the No. 3 connecting pipe 13 can increase the sealing performance of the water pipe to prevent the water inside from spraying out due to poor sealing.

[0046] The use process of the coffee machine extraction device provided by the utility model is as follows:

[0047] When the capsule needs to be extracted, the external water pipe is connected to the No. 1 connecting pipe 71, and the capsule is placed under the output assembly 6. The motor 41 is started to rotate the threaded barrel 42, thereby driving the connecting block 51 threadedly connected thereto to slide downward on the No. 1 connecting plate 32, so that the connecting column 52 and the No. 2 connecting plate 53 drive the mounting column 62 and the mounting plate 61 to move downward. The sliding rod 63 slides inside the threaded barrel 42, so that the mounting plate 61 moves downward to contact the capsule, and the upper edge of the capsule is wrapped by the limiting ring 10, thereby fixing the capsule. At the same time, the needle tube 73 pierces the sealing membrane at the top of the capsule, and the valve of the external water pipe is opened, so that the coffee brewing liquid passes through the No. 1 connecting pipe 71 and the No. 2 connecting pipe 72 and flows out from the outlet of the needle tube 73, so that it is mixed with the coffee powder inside the capsule.

[0048] At this point, the mounting plate 61 and the retaining ring 10 are in contact with the capsule, forming a seal inside the capsule. Liquid is then continuously injected, mixing with the coffee powder, and the pressure inside the capsule increases, eventually breaking the last layer of sealing membrane at the bottom of the capsule, allowing the mixture to flow out through the broken opening in the sealing membrane. A container is placed under the capsule to catch the coffee.

[0049] When it is necessary to connect water pipes of different sizes with the No. 1 connecting pipe 71, the water pipe is passed through the mounting ring 84 through its own toughness and extended to the end of the No. 3 connecting pipe 13. The water pipe is placed on it through the toughness of the No. 1 sealing ring 11. The toughness and softness of the No. 1 sealing ring 11 enable it to connect water pipes of various sizes. Then, the No. 1 connecting ring 81 is rotated so that it gradually moves backward through the threaded connection with the No. 1 connecting pipe 71, and the No. 2 connecting ring 83 is driven to move backward through the No. 3 connecting plate 82. The part of the No. 2 sealing ring 12 located at the front end of the No. 1 sealing ring 11 is further fixed by the No. 1 sealing ring 11 and the No. 2 sealing ring 12 through the squeezing of the water pipe, thereby achieving sealing. The softness of the No. 1 sealing ring 11 and the No. 2 sealing ring 12 can improve the sealing degree while avoiding wearing out the water pipe.
