[0010] In some embodiments, the coffee machine adapter has a recessed holding slot; the holding slot is disposed inside the coffee machine body and connected to the liquid outlet of the pressurizing component; the coffee machine adapter forms a drain channel at the bottom of the holding slot, and the holding slot is connected to the liquid inlet through the drain channel.

[0011] In some embodiments, a sealing boss is formed on the adapter surrounding the receiving slot, the sealing boss being used to seal against the inner wall of the coffee machine body.

[0012] In some embodiments, a spout protrudes from the coffee machine adapter and is inserted into the liquid inlet; the drain outlet of the drain channel is formed at the end of the spout and communicates with the liquid inlet.

[0013] In some embodiments, the adapter has a receiving groove on the first mating end, the receiving groove being arranged around the liquid inlet; a portion of the coffee machine adapter is received in the receiving groove and sealed against the groove wall.

[0014] In some embodiments, the coffee extraction adapter further includes a locking ring; the locking ring is fixedly disposed on the first docking end and partially covers the opening of the receiving groove; the coffee machine adapter is provided with a locking post, and the locking ring is provided with a disassembly notch, through which the locking post is engaged or disengaged from the receiving groove.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0037] Please see Figures 1 to 3One embodiment of the coffee extraction transfer mechanism 100 includes an adapter 110 and a pressure detector 140; the adapter 110 is used to be mounted on the support body 101, and the adapter 110 has a first docking end 1110 and a second docking end 1120; the first docking end 1110 is used to mount the coffee machine body 200, and the second docking end 1120 is used to mount the coffee powder extraction assembly 300; a guide passage 1101 is formed in the adapter 110, and the guide passage 1101 is in the first The docking end 1110 forms a liquid inlet 1111, which is used to connect to the liquid outlet of the pressurizing component 220 inside the coffee machine body 200; the guide passage 1101 forms a drain outlet at the second docking end 1120, which is used to connect to the coffee powder filter cup 320 of the coffee powder extraction component 300; the pressure detector 140 is installed on the adapter 110, and the detection part of the pressure detector 140 is connected to the guide passage 1101 to detect the liquid pressure in the guide passage 1101.

[0038] It is understandable that, since the guide passage 1101 formed in the adapter 110 forms a liquid inlet 1111 at the first docking end 1110, after the coffee machine body 200 is installed at the first docking end 1110 of the adapter 110, the liquid inlet 1111 can be connected with the liquid outlet of the pressurizing component 220 in the coffee machine body 200. At this time, the pressurized liquid after being pressurized by the pressurizing component 220 can enter the guide passage 1101. Meanwhile, since the guide passage 1101 forms a drain port at the second docking end 1120, after the coffee powder extraction assembly 300 is installed at the second docking end 1120 of the adapter 110, the drain port can remain connected to the coffee powder filter cup 320 of the coffee powder extraction assembly 300. At this time, the pressurized liquid is guided into the coffee powder filter cup 320 by the guide passage 1101 to extract the coffee powder. By connecting the detection part of the pressure detector 140 installed on the adapter 110 to the guide passage 1101, the pressure detector 140 can obtain the liquid pressure in the guide passage 1101, thereby obtaining a more accurate pressure during coffee powder extraction. In this way, the user can more accurately adjust the pressurizing assembly 220 to improve the taste of the coffee based on the pressure value obtained by the pressure detector 140.

[0039] Please see Figure 1 In some embodiments, the coffee extraction adapter 100 further includes a coffee machine adapter 120, which is mounted on the first docking end 1110 and is used to adapt to a portion of the coffee machine body 200. It is understood that by adapting the portion of the coffee machine body 200 to the first docking end 1110 via the coffee machine adapter 120, the coffee machine body 200 can be more stably mounted on the first docking end 1110.

[0040] Please see Figure 1 and Figure 3 In this embodiment, the coffee machine adapter 120 is used to fit into a portion inside the coffee machine body 200. The coffee machine adapter 120 forms a barrier within the coffee machine body 200 to reduce leakage from the outlet of the pressurization assembly 220 within the coffee machine body 200. Of course, in other embodiments, the coffee machine adapter 120 may be used to fit into a portion outside the coffee machine body 200 or may be configured in a different way; specific details are not limited here.

[0041] Please see Figure 3 Furthermore, a first mating structure 1210 is formed on the outer wall of the coffee machine adapter component 120. The first mating structure 1210 is used to form a detachable connection with a second mating structure 210 inside the coffee machine body 200. It can be understood that by having the first mating structure 1210 on the outer wall of the coffee machine adapter component 120 mate with the second mating structure 210 inside the coffee machine body 200, the coffee machine body 200 can form a detachable connection with the coffee machine adapter component 120, facilitating quick assembly or disassembly of the coffee machine body 200 and the coffee machine adapter component 120. Specifically, the first mating structure 1210 can be an external thread, and the second mating structure 210 can be an internal thread; alternatively, the first mating structure 1210 can be a snap-fit, and the second mating structure 210 can be a snap-fit ​​opening. These are not limitations, and the first mating structure 1210 and the second mating structure 210 can also adopt other mating forms.

[0042] Please see Figure 1 and Figure 3 In some embodiments, a recessed holding groove 1201 is formed on the coffee machine adapter 120; the holding groove 1201 is disposed within the coffee machine body 200 and connected to the liquid outlet of the pressurizing assembly 220; a drain channel 1202 is formed at the bottom of the holding groove 1201 in the coffee machine adapter 1200, and the holding groove 1201 is connected to the liquid inlet 1111 through the drain channel 1202. It can be understood that since the holding groove 1201 disposed within the coffee machine body 200 is connected to the liquid outlet of the pressurizing assembly 220, the pressurized liquid after being pressurized by the pressurizing assembly 220 can enter the holding groove 1201, and then be guided to the liquid inlet 1111 through the drain channel 1202 formed at the bottom of the holding groove 1201, so that the coffee machine adapter 120, after being partially housed within the coffee machine body 200, can prevent the pressurized liquid from leaking out of the liquid outlet.

[0043] Please see Figure 3In this embodiment, a sealing boss 1220 is formed on the adapter 110 around the container 1201. The sealing boss 1220 is used to seal against the inner wall of the coffee machine body 200. It can be understood that by sealing against the inner wall of the coffee machine body 200 with the sealing boss 1220 formed around the container 1201, the outer periphery of the container 1201 can be sealed, thereby further reducing the leakage of pressurized liquid from the periphery.

[0044] Please see Figure 3 and Figure 4 In some embodiments, a spout 1230 protrudes from the coffee machine adapter 120 and is inserted into the liquid inlet 1111. The drain outlet of the drain channel 1202 is formed at the end of the spout 1230 and communicates with the liquid inlet 1111. It can be understood that by placing the spout 1230 protruding from the coffee machine adapter 120 into the liquid inlet 1111, the drain outlet formed at the end of the spout 1230 communicates with the liquid inlet 1111, thereby allowing more pressurized liquid in the drain channel 1202 to enter the guide path 1101.

[0045] Please see Figure 3 and Figure 4 In some embodiments, the adapter 110 has a receiving groove 1112 on the first mating end 1110, and the receiving groove 1112 is arranged around the liquid inlet 1111; a portion of the coffee machine adapter 120 is received in the receiving groove 1112 and sealed against the groove wall of the receiving groove 1112. It can be understood that because the receiving groove 1112 on the adapter 110 is arranged around the liquid inlet 1111, and the portion of the coffee machine adapter 120 received in the receiving groove 1112 is sealed against the groove wall of the receiving groove 1112, the plug 1230 can be inserted and more tightly connected to the liquid inlet 1111, so as to reduce the leakage of pressurized liquid.

[0046] Please see Figure 3 and Figure 4In some embodiments, the coffee extraction transfer mechanism 100 further includes a locking ring 130; the locking ring 130 is fixedly disposed on the first docking end 1110 and partially covers the opening of the receiving groove 1112; the coffee machine adapter component 120 is provided with a locking post 1130, and the locking ring 130 is provided with a disassembly notch 1301, through which the locking post 1130 is engaged or disengaged from the receiving groove 1112. It is understood that, since the locking ring 130 fixedly installed on the first docking end 1110 partially covers the groove of the receiving groove 1112, when the coffee machine adapter 120 needs to be installed, the locking pin 1130 on the coffee machine adapter 120 can be received in the receiving groove 1112 through the disassembly notch 1301, and the locking pin 1130 interferes with the locking ring 130 to make part of the coffee machine adapter 120 stably received in the receiving groove 1112; and when the coffee machine adapter 120 needs to be disassembled, the locking pin 1130 on the coffee machine adapter 120 can be disassembled out of the receiving groove 1112 through the disassembly notch 1301, thereby realizing the quick separation of the coffee machine adapter 120 from the bracket body 101.

[0047] Please see Figures 1 to 4 This disclosure also provides a coffee machine stand, including a stand body 101 and a coffee extraction adapter 100 according to any of the above embodiments; an adapter 110 is mounted on the stand body 101. It is understood that by mounting the adapter 110 on the stand body 101, the coffee extraction adapter 100 of this disclosure is applied to the coffee machine stand. By connecting the detection part of the pressure detector 140 mounted on the adapter 110 to the flow path 1101, the pressure detector 140 can obtain the liquid pressure within the flow path 1101, thereby more accurately obtaining the pressure experienced during coffee powder extraction. Thus, the user can more accurately adjust the pressurizing component 220 to improve the taste of the coffee based on the pressure value obtained from the pressure detector 140.

[0048] Please see Figures 1 to 5This disclosure also provides a coffee brewing device, including a coffee machine body 200, a coffee powder extraction component 300, and a coffee machine stand for any of the above embodiments; the coffee machine body 200 is installed on the first docking end 1110 of the adapter 110, and the coffee powder extraction component 300 is installed on the second docking end 1120 of the adapter 110; the outlet of the pressurizing component 220 inside the coffee machine body 200 is connected to the coffee powder filter cup 320 of the coffee powder extraction component 300 through a guide passage 1101. It can be understood that since the guide passage 1101 formed inside the adapter 110 forms an inlet 1111 at the first docking end 1110, after the coffee machine body 200 is installed at the first docking end 1110 of the adapter 110, the inlet 1111 can remain connected to the outlet of the pressurizing component 220 inside the coffee machine body 200, and the pressurized liquid after being pressurized by the pressurizing component 220 can enter the guide passage 1101. Meanwhile, since the guide path 1101 forms a drain port at the second docking end 1120, after the coffee powder extraction component 300 is installed at the second docking end 1120 of the adapter 110, the drain port can remain connected with the coffee powder filter cup 320 of the coffee powder extraction component 300. At this time, the pressurized liquid is guided by the guide path 1101 into the coffee powder filter cup 320 to extract coffee powder.

[0049] Please see Figure 1 and Figure 2 In some embodiments, the coffee machine body 200 is the hot water brewing part of a portable pressure coffee machine; while the coffee powder extraction component 300 includes a coffee grounds pusher handle structure 310 and a coffee grounds filter cup 320 with a filter hole of 58mm. The coffee grounds filter cup 320 is mounted on the coffee grounds pusher handle structure 310, which is mounted on the second docking end 1120 of the adapter 110; the pressure detector 140 is a pressure gauge. Of course, this is only an example and is not intended to limit the embodiments of this disclosure. Specifically, the coffee grounds pusher handle structure 310 is mounted upright on the second docking end 1120 of the adapter 110 when extracting coffee grounds, and is mounted upside down on the second docking end 1120 of the adapter 110 when discharging coffee grounds.

[0050] Compared with the prior art, this disclosure has at least the following advantages:

[0051] The coffee extraction transfer mechanism 100 described above has a liquid inlet 1111 formed in the first docking end 1110 of the transfer seat 110 due to the guide passage 1101 formed in the transfer seat 110. After the coffee machine body 200 is installed in the first docking end 1110 of the transfer seat 110, the liquid inlet 1111 can be connected with the liquid outlet of the pressurizing component 220 in the coffee machine body 200. At this time, the pressurized liquid after being pressurized by the pressurizing component 220 can enter the guide passage 1101. Meanwhile, since the guide passage 1101 forms a drain port at the second docking end 1120, after the coffee powder extraction assembly 300 is installed at the second docking end 1120 of the adapter 110, the drain port can remain connected to the coffee powder filter cup 320 of the coffee powder extraction assembly 300. At this time, the pressurized liquid is guided into the coffee powder filter cup 320 by the guide passage 1101 to extract the coffee powder. By connecting the detection part of the pressure detector 140 installed on the adapter 110 to the guide passage 1101, the pressure detector 140 can obtain the liquid pressure in the guide passage 1101, thereby obtaining a more accurate pressure during coffee powder extraction. In this way, the user can more accurately adjust the pressurizing assembly 220 to improve the taste of the coffee based on the pressure value obtained by the pressure detector 140.

[0052] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
