[0033] The coffee brewing mechanism of this embodiment includes a base 100, a capsule holder 200, and a powder holder 300, one of which is selectively mounted on the base 100. The base 100 includes a bracket 130, a filter plate 140, and a flow divider 150. The bracket 130 has a holder mounting hole 110, and the flow divider 150 is mounted at the bottom of the holder mounting hole 110. The flow divider 150 and the bracket 130 are fixed together by screws. The filter plate 140 covers the flow divider 150 and is fixed together by screws. The bracket 130 has a first handle 131 on its outer side. The filter plate 140 has a protrusion 142 on its upper side.

[0034] The capsule holder 200 includes an upper cover 240, a lower support 250, and a piercing element 260. The lower support 250 has a clearance hole, and the piercing element 260 has a spike 230 that passes through the clearance hole. The upper cover 240 and the lower support 250 are fastened and fixed by screws, and the two clamp and fix the piercing element 260. A sealing ring and an outer support 270 are clamped between the upper cover 240 and the lower support 250. The lower side of the lower support 250 forms a capsule receiving groove 210 with an opening facing downwards. The periphery of the opening of the capsule receiving groove 210 has a sealing ring. The outer side of the lower support 250 has a second handle 251. The capsule holder 200 has a water inlet 220 that extends to the bottom of the capsule receiving groove 210.

[0035] When brewing coffee using a coffee capsule, first insert the coffee capsule into the capsule receiving slot 210 of the capsule holder 200. Then, move the capsule holder 200 using the second handle 251 and place it into the holder mounting hole 110 of the bracket 130, ensuring that the periphery of the opening of the capsule receiving slot 210 is sealed against the filter plate 140 via a sealing ring. At this time, the filter plate 140 and the lower support 250 hold the coffee capsule, and the piercing part 260 pierces the upper side of the coffee capsule, i.e., the water inlet side, while the protrusion 142 on the filter plate 140 pierces the water outlet side of the coffee capsule. The coffee brewing mechanism is installed on the coffee machine via the first handle 131. The hot water mechanism pours hot water into the water inlet 220. The hot water enters the coffee capsule from the inlet side, and the brewed coffee flows out from the outlet side of the capsule. After passing through the filter plate 140, it enters the collection tank 151 of the distributor 150 and flows out through the two outlet channels 120, completing the coffee brewing process. After use, by holding the first handle 131 and the second handle 251 respectively, the seat 100 is separated from the capsule holder 200, and the used coffee capsule is removed.

[0036] When brewing coffee powder, first insert the powder holder 300 into the powder holder mounting hole 110, and then add coffee powder into the powder receiving tank 310 of the powder holder 300. Use the first handle 131 to install the coffee brewing mechanism onto the coffee machine. The hot water mechanism pours hot water into the powder receiving tank 310. The brewed coffee liquid passes through the first filter hole 320 and the filter plate 140, enters the liquid collection tank 151 of the separator, and then flows out through the two liquid outlet channels 120, completing the brewing of the coffee liquid.

[0037] Reference Figures 1 to 6 This invention relates to a coffee brewing mechanism, comprising a base 100, a capsule holder 200, and a powder holder 300. The base 100 has a holder mounting hole 110, and the bottom of the holder mounting hole 110 has a liquid outlet channel 120 communicating with the holder mounting hole 110. The capsule holder 200 can be installed in the holder mounting hole 110, and the capsule holder 200 has a capsule receiving groove 210 and a water inlet 220 communicating with the capsule receiving groove 210. The powder holder 300 can be installed in the holder mounting hole 110. A powder receiving tank 310 is provided, and a first filter hole 320 is provided at the bottom of the powder receiving tank 310; wherein the coffee brewing mechanism has a capsule state and a powder state. In the capsule state, the capsule holder 200 is installed in the holder mounting hole 110, and the capsule receiving tank 210 is connected to the liquid outlet channel 120; in the powder state, the powder holder 300 is installed in the holder mounting hole 110, and the first filter hole 320 is connected to the liquid outlet channel 120.

[0038] When a user brews coffee using a coffee capsule, the coffee brewing mechanism is switched to capsule mode. The coffee capsule is placed into the capsule receiving slot 210 of the capsule holder 200, and the capsule holder 200 is installed on the base 100. Hot water is then poured into the coffee capsule through the water inlet 220, and the coffee liquid flows out of the coffee capsule and exits the coffee brewing mechanism through the liquid outlet 120. When a user brews coffee using ground coffee, the coffee brewing mechanism is switched to ground coffee mode. The ground coffee holder 300 is installed on the base 100, and the coffee grounds are placed into the ground coffee receiving slot 310. Hot water is then poured into the ground coffee receiving slot 310, and the coffee liquid is filtered through the first filter hole 320 and exits the coffee brewing mechanism through the liquid outlet 120. The above-described coffee brewing mechanism is applicable to brewing coffee using either coffee capsules or ground coffee, thus possessing high versatility.

[0039] It should be understood that either the capsule holder 200 or the powder holder 300 is selected to be installed on the base 100.

[0040] Specifically, the powder feeder 300 can be equipped with multiple first filter holes 320, such as three, four or more, which can be configured according to actual needs by those skilled in the art.

[0041] In this embodiment, the base 100 includes a bracket 130, a filter plate 140, and a diverter 150. The bracket 130 has a material rack mounting hole 110. The diverter 150 is disposed on the bracket 130 and located at the bottom of the material rack mounting hole 110. The diverter 150 has a liquid collection tank 151 and two liquid outlet channels 120, which are connected to each other. The filter plate 140 is disposed on the bracket 130 and covers the opening of the liquid collection tank 151. The filter plate 140 has a plurality of second filter holes 141 that are connected to the liquid collection tank 151. The filter plate 140, with its second filter holes 141, can further filter the coffee liquid, reducing the risk of fine particles mixed in with the coffee liquid, and can also slow down the flow of the coffee liquid, allowing it to pass relatively smoothly through the second filter holes 141 into the liquid collection tank 151, which is beneficial for a more uniform coffee liquid flow. After the coffee liquid is collected in the collection tank 151, it flows out of the coffee brewing mechanism through the dispensing channel 120. The user can place the cup in the dispensing channel 120 to collect the coffee liquid. The configuration of two dispensing channels 120 allows for the simultaneous brewing of two cups of coffee, improving the efficiency of coffee brewing.

[0042] In this embodiment, the coffee brewing mechanism is in capsule state. The capsule holder 200 and the diverter 150 are placed on both sides of the filter plate 140. The opening of the capsule receiving groove 210 faces the filter plate 140. The filter plate 140 covers the opening of the capsule receiving groove 210. The filter plate 140 and the capsule holder 200 enclose each other to form a capsule receiving cavity. The capsule receiving groove 210 is connected to the liquid collection groove 151 through the second filter hole 141. The water inlet 220 is located at the bottom of the capsule receiving groove 210. The capsule holder 200 and the filter plate 140 are in contact and sealed. When the coffee brewing mechanism switches to capsule mode, the coffee capsule is first inserted into the capsule receiving slot 210, and then the capsule holder 200 is inserted into the holder mounting hole 110. At this time, the filter plate 140 and the capsule holder 200 together hold the coffee capsule. Hot water is poured into the coffee capsule through the water inlet 220, and the coffee liquid flows out from the side of the coffee capsule closest to the filter plate 140, passes through the second filter hole 141 and enters the collection tank 151. Then the coffee liquid flows out through the liquid outlet channel 120. Afterwards, the capsule holder 200 can be removed, and the discarded coffee capsule can be taken out of the capsule receiving slot 210 and discarded. The above-described coffee brewing mechanism is relatively convenient to use when brewing with coffee capsules, and the brewing effect is good.

[0043] Specifically, the capsule holder 200 has a sealing ring on the side near the filter plate 140, which allows the two to seal and come into contact.

[0044] In this embodiment, the filter plate 140 has multiple protrusions 142 on the side near the capsule receiving groove 210. Each protrusion 142 is conical, with a pointed end away from the collection groove 151. The multiple protrusions 142 create an uneven surface on the side of the filter plate 140 near the capsule receiving groove 210, preventing the filter plate 140 from fitting too tightly to the coffee capsule and obstructing the flow of coffee liquid. The protrusions 142 also guide the flow of coffee liquid, facilitating its movement. The pointed ends of the protrusions 142 can also puncture one side of the coffee capsule, allowing coffee liquid to flow out.

[0045] Specifically, the filter plate 140 is provided with multiple rows of second filter holes 141, each row of second filter holes 141 including a plurality of second filter holes 141, and a protrusion 142 is provided between two adjacent second filter holes 141. It is conceivable that in other embodiments, the protrusion 142 and the second filter holes 141 may also be arranged in other ways, such as the second filter holes 141 and the protrusion 142 being arranged in a ring.

[0046] Specifically, the second filter hole 141 can be provided with, for example, three, four or more, and the protrusion 142 can also be provided with three, four or more, which can be configured according to actual needs by those skilled in the art.

[0047] In this embodiment, the water inlet 220 is located at the bottom of the capsule receiving groove 210, and the capsule holder 200 is provided with a spike 230 for piercing the capsule at the bottom of the capsule receiving groove 210. With the spike 230 in place, during the process of placing the coffee capsule into the capsule receiving groove 210 and installing the capsule holder 200 into the holder mounting hole 110, the spike 230 can pierce the water inlet side of the coffee capsule, thus facilitating the injection of hot water into the coffee capsule without pre-piercing it, making it relatively convenient to use.

[0048] In this embodiment, the capsule holder 200 is provided with three spikes 230, all of which are evenly arranged around the water inlet 220. The three spikes 230 surrounding the water inlet 220 facilitate the creation of several water inlet holes on the water inlet side of the coffee capsule, allowing hot water injected through the water inlet 220 to flow quickly and evenly into the coffee capsule, resulting in better performance. It is conceivable that in other embodiments, the number of spikes 230 can be other, such as one, two, four, or more, and those skilled in the art can configure them according to actual needs.

[0049] It is conceivable that, in some other embodiments, the capsule holder 200 may also be a one-piece molded structure.

[0050] Specifically, the bracket 130 is provided with a first handle 131, and the capsule holder 200 is provided with a second handle 251. Since the bracket 130 is part of the base 100, the first handle 131 makes it convenient for the user to hold the base 100, and the second handle 251 makes it convenient for the user to hold the capsule holder 200, making it relatively convenient to install or remove and replace the capsule holder 200; and it can reduce the risk of burning hands in the coffee brewing mechanism.

[0051] Specifically, the axis of the mounting hole 110 is vertically oriented. When the powder holder 300 or capsule holder 200 is installed on the base 100, both the powder holder 300 and capsule holder 200 are located above the filter plate 140, while the flow divider 150 is located below the filter plate 140. When the coffee brewing mechanism is in powder form, hot water is poured into the powder receiving tank 310. Under gravity, the coffee liquid passes sequentially through the first filter hole 320, the confluence chamber 330, the slow flow hole 340, the second filter hole 141, and the collection tank 151, finally flowing out from the outlet channel 120. When the coffee brewing mechanism is in capsule form, hot water is injected into the coffee capsule through the water inlet 220. Under gravity, the coffee capsule flows out and passes through the second filter hole 141 into the collection tank 151, finally flowing out from the outlet channel 120.

[0052] In this embodiment, the powder holder 300 is provided with a confluence cavity 330, which is connected to the powder receiving tank 310 through a first filter hole 320. The confluence cavity 330 is provided with a slow-flow hole 340 for allowing liquid to flow out of the powder holder 300. Coffee powder is placed into the powder receiving tank 310, and then hot water is poured into the powder receiving tank 310 to form coffee liquid. The coffee liquid passes through the first filter hole 320 and enters the confluence cavity 330, while the coffee powder remains in the powder receiving tank 310. The coffee liquid in the confluence cavity 330 slowly flows out of the powder holder 300 through the slow-flow hole 340, allowing the liquid to remain in the powder receiving tank 310 and the confluence cavity 330 for a longer period of time. This facilitates the thorough soaking and brewing of the coffee powder by the hot water, resulting in a better brewing effect.

[0053] Specifically, the bottom of the powder container 310 is provided with multiple first filter holes 320, and the cavity wall of the confluence cavity 330 is provided with a slow flow hole 340. The cross-sectional areas of the first filter holes 320 and the slow flow hole 340 are similar, so that the slow flow hole 340 allows the coffee liquid to slowly flow out of the powder rack 300, thereby allowing the liquid to fully soak and brew the coffee powder.

[0054] In this embodiment, a first overlapping portion 350 is provided on the outer periphery of the powder holder 300. When the coffee brewing mechanism is in the powder state, the first overlapping portion 350 overlaps with the periphery of the opening of the holder mounting hole 110. The powder holder 300 is provided with the first overlapping portion 350. When the first overlapping portion 350 overlaps with the periphery of the opening of the holder mounting hole 110, the powder holder 300 is installed in place on the base 100, making the installation process relatively simple. Specifically, the first overlapping portion 350 is an annular plate provided on the outer periphery of the powder holder 300. It is understood that in other embodiments, the first overlapping portion 350 can also be other structures, such as a protrusion provided on the outer periphery of the powder holder 300.

[0055] In this embodiment, the powder holder 300 is provided with a snap-fit ​​portion 360, and the wall of the holder mounting hole 110 is provided with a snap-fit ​​mating portion 160. When the coffee brewing mechanism is in powder form, the snap-fit ​​portion 360 engages with the snap-fit ​​mating portion 160. The snap-fit ​​between the powder holder 300 and the base 100 prevents the powder holder 300 from loosening or shaking when installed on the base 100, thus improving the stability of the coffee brewing mechanism. Specifically, the snap-fit ​​mating portion 160 is an annular groove provided on the wall of the holder mounting hole 110, and the snap-fit ​​portion 360 is a snap-fit ​​protrusion provided on the outer periphery of the powder holder 300. It is conceivable that in other embodiments, the snap-fit ​​mating portion 160 may also be a snap-fit ​​protrusion provided on the wall of the holder mounting hole 110, and the snap-fit ​​portion 360 may be a groove provided on the outer periphery of the powder holder 300.

[0056] Specifically, the powder material holder 300 is a metal component, which is relatively durable. The protruding part is a protruding structure integrally formed by the powder material holder 300, and the first overlapping part 350 is also an annular plate integrally formed by the powder material holder 300.

[0057] This utility model also discloses a coffee machine that uses the aforementioned coffee brewing mechanism. Because of this brewing mechanism, the coffee machine is compatible with both coffee powder and coffee capsules, exhibiting good versatility.
