Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee machines, and more particularly to a puncture structure for a coffee machine. Background Technology
[0002] A capsule coffee machine consists of a manufacturer pre-filling coffee powder into a jelly-like plastic capsule, then filling it with nitrogen to preserve it. When you want coffee, simply insert the capsule into the machine for a quick and easy brewing process. The general procedure is as follows: First, open the capsule inlet cap, insert the capsule, close the cap, and press the switch to begin brewing. During brewing, the capsule membrane is pierced by a needle, and then heated water quickly enters the capsule under pressure. The coffee powder is extracted through the internal filter and flows into the coffee cup below, completing the brewing process. To brew more coffee, simply open the cap, insert a new capsule, and start the brewing process again.
[0003] Existing capsule coffee machines use a water-permeable piercing needle in a hinged top cover to puncture the coffee-ground capsules located in the base. Hot water flows into the capsule through the needle's outlet, mixes with the coffee grounds, and then flows out. However, some existing coffee machines have a fixed piercing needle. This design could cause users to puncture the capsule or prick their hand before the coffee is extracted, affecting usability. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a puncture structure for a coffee machine, based on the current state of the technology.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A puncture structure for a coffee machine includes a capsule drawer with a locking structure on its exterior. The capsule drawer is connected to the coffee machine via the locking structure. An extraction unit and a puncture cavity positioned above the extraction unit are arranged inside the capsule drawer. A needle capable of vertical movement is arranged within the puncture cavity, and an elastic element is sleeved around the needle. When the capsule drawer is connected to the coffee machine, the coffee machine contacts the needle, and the needle then moves downward into the extraction unit. When the capsule drawer is separated from the coffee machine, the needle returns to its original position upward via the elastic element.
[0007] The aforementioned components achieve the following effects: a locking structure connects the coffee machine and the capsule drawer; an extraction unit holds the capsules for extraction; a piercing chamber contains a needle for piercing; and an elastic element repositions the needle. When the capsule drawer is connected to the coffee machine, the needle contacts the machine and then moves downwards to pierce the coffee capsule for extraction. When the capsule drawer is separated from the coffee machine, the needle repositions itself via the elastic element, preventing injury to the user when removing or inserting the capsule.
[0008] Preferably, the tip of the needle is provided with a water inlet; a limiting part is provided extending outward from any position on the outer periphery of the needle; a first water outlet is provided at the bottom of the needle; and a second water outlet is provided on the outer periphery of the needle below the limiting part.

[0010] Preferably, a first through hole is arranged at the upper end of the puncture cavity; a second through hole, identical to that of the extraction unit, is arranged at the bottom of the puncture cavity; and the needle slides between the first and second through holes by a limiting part.
[0011] The effect achieved by the above components is as follows: by providing a first through hole, the water inlet end of the piercing needle will be exposed from the first through hole when the piercing needle is not performing piercing work; by providing a second through hole, the water inlet end of the piercing needle will be exposed from the second through hole when the piercing needle is performing piercing work.
[0012] Preferably, the capsule drawer is provided with a water inlet that communicates with the puncture cavity.
[0013] The effect achieved by the above-mentioned components is that, by setting up a water inlet, water can enter the puncture chamber from the water inlet, and then the extraction work is carried out through the puncture needle.
[0014] Preferably, the extraction unit is provided with a water outlet at the bottom.
[0015] The effect achieved by the above-mentioned components is that, by setting up a water outlet, the extracted coffee liquid is allowed to flow out.
[0016] Preferably, the locking structure includes any one of snap-locking, threaded locking, or magnetic locking.
[0017] The effect achieved by the above components is that, by setting different locking structures, they can be adapted to coffee machines with different structures.
[0018] Preferably, a waterproof ring is provided at the connection between the extraction unit, the puncture chamber, and the capsule drawer.
[0019] The effect achieved by the above-mentioned components is that, by setting up a waterproof ring, they prevent water from overflowing.
[0020] Compared with the prior art, the advantages of this utility model are as follows: a locking structure is provided to connect the coffee machine and the capsule drawer; an extraction unit is provided to place the capsule for extraction; a piercing cavity is provided, and a needle is provided in the piercing cavity for piercing; an elastic element is provided for the elastic reset of the needle; when the capsule drawer is connected to the coffee machine, the needle will abut against the coffee machine and then move downward to pierce the coffee capsule for extraction; when the capsule drawer is separated from the coffee machine, the needle will be reset by the elastic element to prevent the user from being injured when taking out or putting in the coffee capsule.
