[0026] like Figures 1 to 3 As shown, a detachable coffee machine according to a first aspect embodiment of the present invention includes a base 100, a cover 200, a heating assembly 300, and a filter shell 400. The cover 200 and the base 100 are connected to form a first cavity 210 capable of containing coffee liquid. The heating assembly 300 is disposed on the base 100 and is used to heat the coffee liquid in the first cavity 210. The filter shell 400 is disposed inside the cover 200 and has a second cavity 420 capable of containing coffee beans. The second cavity 420 is located above the first cavity 210. The filter shell 400 is provided with a plurality of first drip holes 430 respectively communicating with the first cavity 210 and the second cavity 420. The cover 200 and the base 100 are detachably connected.

[0027] The base 100 can be frustum-shaped or rectangular, and the cover 200 can be made of acrylic material or heat-resistant resin material. The cover 200 can be transparent or semi-transparent so that the user can see the coffee liquid preparation status in the first cavity 210.

[0028] The heating component 300 can be located on the upper surface of the base 100, so that the heating component 300 can be located in the first cavity 210 after the first cavity 210 is formed to heat the liquid.

[0029] The filter housing 400 can be made of alloy material. The filter housing 400 can be in the shape of an inverted frustum or a pyramid. The first drip hole 430 has a small aperture, which makes it difficult for ground coffee beans to pass through, but allows liquid to pass through. The first drip hole 430 can be set on the side wall of the filter housing 400 or on the bottom wall of the filter housing 400.

[0030] This utility model relates to a detachable coffee machine. The user adds ground coffee beans to the second chamber 420. The first drip hole 430 has a small diameter, restricting the passage of coffee beans but allowing liquid to pass through. The user adds water to the second chamber 420, which extracts coffee from the beans to form coffee liquid, which drips into the first chamber 210 through the first drip hole 430. The heating element 300 heats the coffee liquid in the first chamber 210. After coffee production, the user can detach the cover 200 from the base 100. Since the heating element 300 is located on the base 100, it is not detached with the cover 200. Due to the filtering effect of the filter shell 400, virtually no coffee beans fall onto the base 100. The user only needs to clean the base 100 lightly, as water is unlikely to enter the base 100. The cover 200 and filter shell 400 can be deeply cleaned by rinsing. This design is convenient to use and allows for deep cleaning.

[0031] In some embodiments of this utility model, the heating assembly 300 includes a heating element 310 and a heat-conducting plate 320. The heat-conducting plate 320 is disposed on the base 100 to correspond to the first cavity 210. The heating element 310 is disposed inside the base 100. The heating element 310 and the heat-conducting plate 320 are heated so that heat can be conducted to the first cavity 210 through the heat-conducting plate 320.

[0032] The heat conduction plate 320 can be made of an alloy material with good thermal conductivity. The heat conduction plate 320 can be connected to the base 100 and serve as the upper surface of the base 100. The lower surface of the heat conduction plate 320 corresponds to the interior of the base 100. The upper surface of the heat conduction plate 320 serves as at least part of the wall surface of the first cavity 210. The heating element 310 can be a semiconductor heating element or a resistive heating element.

[0033] Specifically, a control module 130 may also be provided inside the base 100. The control module 130 can be connected to the heating element 310 to apply current to drive the heating element 310 to generate heat. A control panel 140 may be provided on the surface of the base 100. The control panel 140 is provided with push-buttons, capacitive touch parts, etc. The user operates the control panel 140 to generate operation commands. The control module 130 includes an MCU or CPU and its auxiliary circuits. The control module 130 is electrically connected to the control panel 140. The control module 130 can generate control commands according to the operation commands to control the operation of the heating element 310.

[0034] In some embodiments of this utility model, such as Figure 2 , 3 As shown, the cover 200 is cylindrical, and the bottom end of the cover 200 is connected to the base 100 through a first threaded structure 120.

[0035] The upper surface of the base 100 can cooperate with the inner wall of the cover 200 to form a first cavity 210, and the heat conduction plate 320 can serve as the bottom surface of the first cavity 210. The heat emitted by the heating element 310 can fully heat the liquid in the first cavity 210. The base 100 is provided with a first convex ring 110 formed around the heat conduction plate 320. The first thread structure 120 includes an internal thread provided on the inner side wall of the first convex ring 110 and an external thread provided on the outer side wall of the cover 200. The internal thread and the external thread are connected so that the bottom end of the cover 200 can be detachably connected to the base 100.

[0036] In some embodiments of this utility model, such as Figure 2 , 3 As shown, the detachable coffee machine also includes a liquid supply module 500, which is detachably disposed on the base 100. The input end of the liquid supply module 500 is located in the first cavity 210, and the output end of the liquid supply module 500 extends into or above the second cavity 420. The liquid supply module 500 is used to transfer the coffee liquid in the first cavity 210 to the second cavity 420 for output.

[0037] The filter housing 400 can be connected to the inner wall of the cover 200 or to the liquid supply module 500. The liquid output from the output end of the liquid supply module 500 first enters the second cavity 420 under the action of gravity, and then enters the first cavity 210 through the first drip hole 430.

[0038] When a user needs to obtain coffee liquid, they can first add an appropriate amount of water to the first cavity 210, and then put the ground coffee beans into the second cavity 420. Due to the obstruction of the filter shell 400, the coffee beans will not fall into the first cavity 210. The output end of the liquid supply module 500 obtains the liquid from the first cavity 210 and then transmits it to the second cavity 420 or to the top of the second cavity 420. The liquid is sprayed onto the coffee beans and then drips back into the first cavity 210 from the first drip hole 430. The liquid supply module 500 repeatedly transmits the liquid from the first cavity 210 to the second cavity 420 to make coffee liquid. Moreover, the contact time between the liquid and the coffee beans is short, and the coffee beans are less likely to extract too many bitter substances.

[0039] In some embodiments of this utility model, a driving member 600 is provided inside the base 100, and the driving part 610 of the driving member 600 passes through the base 100 to be located in the first cavity 210. The liquid supply module 500 includes a liquid pump assembly 510 and a liquid delivery assembly 520. The liquid pump assembly 510 is detachably disposed in the base 100, and the driving part 610 of the driving member 600 is detachably connected to the liquid pump assembly 510 to drive the liquid pump assembly 510 to operate. The input end of the assembly 500 is located at the liquid pump assembly 510. The first end of the infusion assembly 520 is connected to the liquid pump assembly 510. The filter housing 400 is provided with a first mounting port 410. The infusion assembly 520 is detachably installed in the filter housing 400 through the first mounting port 410 so that the tail end of the infusion assembly 520 extends into or above the second cavity 420. The output end of the liquid supply module 500 is located at the tail end of the infusion assembly 520.

[0040] The drive unit 600 can be a motor or a rotary cylinder, and is also located inside the base 100. The drive part 610 of the drive unit 600 can pass through the base 100 and protrude from the upper surface of the base 100. The drive unit 600 drives the drive part 610 to rotate, and the drive part 610 provides power for the operation of the liquid pump assembly 510, thereby drawing liquid from the first cavity 210. The filter shell 400 is provided with a first mounting port 410 near the middle position. The infusion assembly 520 can pass through the first mounting port 410 so that the tail end of the infusion assembly 520 extends into or above the second cavity 420.

[0041] According to the user's needs, the heating component 300 can heat the liquid in the first cavity 210, and the liquid supply module 500 can transfer and spray the heated liquid onto the coffee beans to extract coffee liquid. Of course, it should be noted that coffee liquid can also be extracted without heating the liquid in the first cavity 210.

[0042] The liquid pump assembly 510 includes a pump housing 511 and an impeller 512. The pump housing 511 has a pump chamber 514 inside. The pump housing 511 has an inlet 515 communicating with the pump chamber 514 to form the input end of the liquid supply module 500. The pump housing 511 has an outlet 516 communicating with the pump chamber 514 to communicate with the first end of the liquid pump assembly 510. The impeller 512 is located in the pump chamber 514. The drive part 610 of the drive member 600 is connected to the impeller 512 to drive the impeller 512 to rotate.

[0043] The pump housing 511 can be mounted on the surface of the base 100 by means of a snap-fit, screw, suction cup, or other structure to allow the pump assembly 510 to be detachably mounted on the base 100. The drive part 610 of the drive member 600 can be a convex shaft protruding from the upper surface of the base 100. The convex shaft rotatably passes through the base 100. The cross-section of the convex shaft is non-circular. The impeller 512 has a rotating shaft in the middle. The rotating shaft rotatably passes through the pump housing 511. The rotating shaft has a non-circular shaft hole 513 in the middle. The drive part 610 of the drive member 600 can pass into the shaft hole 513. The non-circular structure restricts the relative rotation between the drive part 610 of the drive member 600 and the impeller 512. Thus, the drive member 600 can drive the impeller 512 to rotate.

[0044] The inlet 515 is located above the pump housing 511, while the outlet 516 is located on the side wall of the pump housing 511. When the impeller 512 rotates, it can apply force to the liquid entering the pump chamber 514 and pump the liquid from the outlet 516 into the delivery assembly 520.

[0045] In some embodiments of this utility model, such as Figure 2 , 3 As shown, the infusion assembly 520 includes an infusion tube 521 and a diffuser cap 523. The first end of the infusion tube 521 is connected to the outlet 516. The infusion tube 521 can be vertically arranged and pass through the filter shell 400 so that the tail end of the infusion tube 521 extends into or above the second cavity 420. The diffuser cap 523 is connected to the tail end of the infusion tube 521 and is located in front of the tail end port of the infusion tube 521. There is an outlet gap between the tail end port of the infusion tube 521 and the diffuser cap 523 to form the output end of the infusion supply module 500.

[0046] The liquid pump assembly 510 pumps liquid into the transmission pipe of the infusion assembly 520, and the liquid can be sprayed out from the tail end port of the infusion tube 521. In order for the liquid to contact the coffee beans in the second cavity 420 more evenly, the diffuser cap 523 is located in front of the tail end port of the infusion tube 521 to form a shield, and the surface of the diffuser cap 523 facing the tail end port of the infusion tube 521 can be an arc surface. The tail end port of the infusion tube 521 is sprayed as close as possible to the center of the diffuser cap 523. The liquid is shielded by the diffuser cap 523 and splashes outward in a ring direction.

[0047] In some embodiments of this utility model, such as Figure 2 As shown, the first end of the infusion tube 521 is connected to the liquid pump assembly 510, and the tail end of the infusion tube 521 extends into or above the second cavity 420. A receiving platform 522 is provided on the outer peripheral wall of the infusion tube 521, and the filter shell 400 abuts against the receiving platform 522 to achieve a detachable connection with the infusion assembly 520.

[0048] The infusion tube 521 passes through the first mounting port 410, while the receiving platform 522 cannot pass through the first mounting port 410. The bottom wall of the filter housing 400 abuts against the upper surface of the receiving platform 522. When the user needs to disassemble the filter housing 400, he / she only needs to move the filter housing 400 upward so that the filter housing 400 can be pulled out from the top of the cover 200.

[0049] In some embodiments of this utility model, such as Figure 2 , 3 As shown, the detachable coffee machine also includes an ice storage shell 700, which has a third cavity 710. The ice storage shell 700 is detachably connected to the top of the cover 200. The third cavity 710 is located above the second cavity 420. The bottom of the ice storage shell 700 has a second drip hole 730 that can connect the second cavity 420 and the third cavity 710. The ice storage shell 700 has a second mounting port 720 that allows the output end of the liquid supply module 500 to pass through.

[0050] Understandably, the ice storage shell 700 is provided with a second mounting port 720. The liquid supply module 500's inlet tube 521 can pass through the second mounting port 720 to extend above the ice storage shell 700. Ice cubes are placed on the ice storage shell 700, and the liquid supply module 500 can transfer liquid to the location of the ice cubes. The liquid acts on the surface of the ice cubes, causing the surface of the ice cubes to melt, thus lowering the liquid temperature. Then, the liquid drips onto the coffee beans through the second drip hole 730 for extraction, completing the preparation of iced coffee.

[0051] In some embodiments of this utility model, such as Figure 2 ,3 As shown, the top of the cover 200 is connected to the ice storage shell 700 via a second threaded structure 740.

[0052] Specifically, a second protruding ring 750 is provided at the bottom of the ice storage shell 700, and the second thread structure 740 includes an internal thread provided on the inner side wall of the second protruding ring 750 and an external thread provided on the outer side wall of the top of the cover 200. The internal thread and the external thread are connected so that the bottom end of the cover 200 is detachably connected to the ice storage shell 700.

[0053] In some embodiments of this utility model, the detachable coffee machine also includes a lid 800, and the top of the ice storage shell 700 is provided with an opening. The tops of the lid 800 and the ice storage shell 700 are detachably connected so that the opening can be opened or closed. The user can open the lid 800 to add ice cubes to the third cavity 710 or add water to the first cavity 210.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
