Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a coffee machine with double brewing modes. Background Art

[0002] At present, there are dual-brewing mode coffee machines on the market, that is, one coffee machine can make both drip coffee and capsule coffee. The disadvantages are: it is necessary to manually switch the brewing function, manually switch the operating system, and replace the filter or capsule shell, which results in a poor user experience.

[0003] For example, a Chinese utility model patent with authorization announcement number CN218552089U discloses a dual-purpose coffee machine, which includes a coffee funnel assembly, which is provided with openings at the top and bottom, and a channel for coffee liquid to flow out is formed through the top cover assembly, which is connected to the upper end opening of the coffee funnel assembly, and includes a top cover member for closing the upper end opening of the coffee funnel assembly, a shower member provided at one end of the top cover member facing the coffee funnel assembly, and a piercing member provided on the top cover member and capable of penetrating the shower member, and the shower member can be connected to the top cover member. The top cover is lifted and lowered; the capsule funnel is detachably mounted on the top cover assembly or the coffee funnel assembly; wherein the coffee machine includes two use states; first, when the capsule funnel is mounted on the top cover assembly or the coffee funnel assembly, the shower head is forced to move in a direction away from the coffee funnel assembly, and the piercing member extends into the capsule funnel to discharge water to make capsule coffee; second, when the capsule funnel is removed from the top cover assembly or the coffee funnel assembly, the piercing member is connected to the shower head, and the shower head discharges water to make drip coffee. This prior art can be used to make both capsule coffee and drip coffee, but the prior art has a complex structure and high cost, and when switching to make different coffee liquids, it is necessary to manually assemble the capsule funnel or manually disassemble the capsule funnel to switch modes, which is inconvenient to use and does not provide an ideal user experience.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In response to the problems in the prior art, the utility model provides a coffee machine with dual brewing modes, which can be used to make both capsule coffee and drip coffee, and does not require manual loading and unloading of the capsule holder to achieve the conversion. The machine is more convenient to use and provides a better user experience.

[0006] In order to achieve the above purpose, the technical solution applied by the utility model is as follows:

[0007] A coffee machine with dual brewing modes comprises a coffee machine body, wherein a detachable filter assembly is installed on the coffee machine body, the filter assembly comprises a filter, a water outlet needle cover, a second compression spring and a water outlet needle, the water outlet needle is fixed to the filter, the water outlet needle cover is movably arranged on the filter, the water outlet needle cover and the water outlet needle are slidably arranged, and the two ends of the second compression spring respectively abut against the water outlet needle cover and the filter; a top cover, wherein the top cover is hinged to the coffee machine body, a water inlet assembly is fixed on the top cover, the water inlet assembly comprises a water inlet pipe, a shower and a first compression spring, the water inlet pipe is fixed on the top cover, a water inlet needle is fixed on the water inlet pipe, a water outlet hole is provided on the water inlet needle, the shower is movably arranged on the top cover, a water inlet needle sealing ring is fixed on the shower, the water inlet needle and the water inlet needle sealing ring are slidably arranged, and the two ends of the first compression spring respectively abut against the water inlet pipe and the shower; a capsule holder, wherein the capsule holder is hinged to the coffee machine body, the capsule holder is located between the water inlet assembly and the filter assembly, and the capsule holder is used to support the capsule. In this way, it has two brewing modes: when no capsule is placed on the capsule holder, under the action of the first compression spring, the water inlet pipe is in a jacking state, the water outlet hole on the water inlet needle is located above the water inlet needle sealing ring, and water flows into the shower head through the water outlet hole of the water inlet needle, and flows into the filter through the drip hole of the shower head to brew coffee powder, and at the same time, under the action of the second compression spring, the water outlet needle cover is in a jacking state to hide the water outlet needle to prevent coffee powder from entering the water outlet needle. At this time, the working mode is the coffee powder drip brewing mode; when the capsule is placed on the capsule holder, the upper end of the capsule jacks up the shower head and the water inlet needle sealing ring, the water inlet needle passes through the water inlet needle sealing ring to be exposed, pierces the upper end of the capsule, and water flows into the capsule through the water outlet hole of the water inlet needle for brewing, and at the same time, the lower end of the capsule presses down the water outlet needle cover, the water outlet needle passes through the water outlet needle cover to be exposed, and pierces the bottom of the capsule. At this time, the working mode is the capsule brewing mode;

[0008] In actual application, when putting coffee powder, just flip open the top cover and the capsule holder to put it in; when putting capsules in, just flip open the top cover to put it in, which is easy to operate.

[0009] It should be noted that the switch between the drip brewing mode and the capsule brewing mode does not require manual loading and unloading of the capsule holder to achieve the switch, which is more convenient to use and provides a better user experience.

[0012] According to the above scheme, a water pipe cover is sealed and connected to the water inlet pipe, the water pipe cover is fixed on the top cover, and a water inlet needle is fixed to the water outlet of the water inlet pipe.

[0013] According to the above solution, a dripping hole is provided on the shower head, and when the water outlet hole of the water inlet needle is located above the water inlet needle sealing ring, the water outlet hole is correspondingly connected to the dripping hole.

[0014] According to the above scheme, the water outlet needle cover is provided with a perforation, a water outlet needle sealing ring is provided in the perforation, the water outlet needle and the water outlet needle sealing ring are arranged to slide and seal, a second sharp point is provided at the upper end of the water outlet needle, and a water outlet channel is formed in the water outlet needle. In this way, the second sharp point at the upper end of the water outlet needle is used to pierce the bottom of the capsule, and the coffee liquid flows out through the water outlet channel; it should be noted that under the action of the second compression spring, the water outlet needle cover is in a jacking state, hiding the water outlet needle, and under the action of the water outlet needle sealing ring, coffee powder can be prevented from entering the water outlet needle, and on the other hand, the water outlet needle can be prevented from hurting hands when cleaning the filter.

[0015] According to the above solution, a water outlet needle cover sealing ring is provided between the outer wall of the water outlet needle cover and the filter screen, so as to prevent coffee powder and coffee liquid from entering between the outer wall of the water outlet needle cover and the filter screen.

[0016] According to the above solution, a filter cover is fixedly connected to the bottom of the filter, and a filter is arranged on the filter cover. In this way, the coffee liquid is filtered through the filter.
