Description

Technical Field

[0001] This invention belongs to the field of coffee machine technology, and particularly relates to coffee powder dispensing components, coffee powder dispensers, and coffee machines. Background Technology

[0002] During the grinding process, coffee beans generate static electricity through friction with the burrs, leading to flyaways, clumping, and uneven density within the coffee grounds. As coffee grounds fall from the grinder, they accumulate from the center outwards, eventually forming a pointed pile that is wider at the bottom than the top. For example, Chinese patent CN216854492U discloses a connection structure between a coffee grinder and a funnel. This structure includes a coffee machine and a funnel. The coffee machine has a base and a funnel holder mounted on the base. The funnel is installed on the funnel holder to receive the coffee grounds after grinding. In this structure, the coffee grounds in the funnel form a pointed pile that is wider at the bottom than the top. If this type of coffee grounds is directly compressed without pretreatment, the resulting coffee puck will be uneven. Using such a coffee puck during brewing will create a significant channeling effect, resulting in uneven brewing pressure. This will lead to brewing failure and affect the quality of the coffee. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a coffee powder dispensing component, a coffee powder dispenser, and a coffee machine.

[0004] The technical solution adopted in the embodiments of the present invention is as follows:

[0005] A coffee powder distribution assembly, characterized in that the coffee powder distribution assembly comprises:

[0006] A powder tube is placed vertically with open top and bottom ends. A powder tray is provided inside the powder tube, and the outer periphery of the powder tray is connected to the inner wall of the powder tube. Powder holes are provided on the powder tray.

[0007] A powder scraper and a powder applicator are respectively disposed inside the powder dispersing cylinder. The powder scraper is rotatably disposed above the powder dispersing disc, and the powder applicator is rotatably disposed below the powder dispersing disc. The powder applicator is provided with a powder dispersing cavity, and the bottom of the powder applicator is provided with multiple powder dispersing ports communicating with the powder dispersing cavity.

[0008] A power mechanism is used to drive the scraper and the powder distribution head to rotate, so that the scraper can spread the coffee powder on the powder tray and let it fall into the powder distribution chamber through the powder distribution hole, and evenly sprinkle it out through the powder distribution port.

[0009] Furthermore, the bottom of the powder tray is equipped with a powder-sweeping plate that extends into the powder-dispensing chamber. When the powder-dispensing head rotates, the powder-sweeping plate pushes the coffee powder in the powder-dispensing chamber into the powder-dispensing opening. In this way, as the powder-dispensing head rotates, the powder-sweeping plate can continuously sweep the coffee powder in the powder-dispensing chamber to the powder-dispensing opening, preventing excessive accumulation of coffee powder in the powder-dispensing chamber.

[0010] Furthermore, the powder distribution chamber is a cylindrical cavity with an open top, and multiple powder distribution ports are arranged on the bottom surface inside the cylindrical cavity. Each powder distribution port expands from the center of the cylindrical cavity towards the inner wall to form a fan shape. In this way, with the help of the powder sweeping plate, coffee powder is continuously swept to the powder distribution port inside the powder distribution chamber, and the coffee powder can be evenly distributed. The distributed coffee powder accumulates layer by layer, eventually forming a coffee powder cake with a uniform interior.

[0011] Furthermore, the coffee powder distribution assembly also includes a connecting post. The powder dispensing tray has a central hole, and the connecting post passes through the central hole. Both ends of the connecting post are fixedly connected to the powder scraper and the powder distribution head, respectively. The power mechanism is driven by the powder scraper and drives the powder scraper and the powder distribution head to rotate synchronously via the connecting post. The connecting post passing through the central hole of the powder dispensing tray and connecting to both the powder distribution head and the powder scraper allows for synchronous rotation of the powder distribution head and the powder scraper. This simplifies the structure, as both can be rotated using only one power mechanism.

[0012] Furthermore, the edge of the scraper facing the powder tray is serrated or comb-shaped so as to scrape apart the clumps of coffee powder on the powder tray and then let it fall into the powder distribution chamber of the powder distribution head through the powder distribution hole.

[0013] Furthermore, the power mechanism includes:

[0014] A rotating frame is disposed inside the powder dispersing cylinder. The rotating frame is cylindrical and has an annular toothed ring on its outer peripheral wall. The powder scraper is disposed on the rotating frame.

[0015] The driven gear is disposed outside the powder dispersing cylinder and passes through the powder dispersing cylinder to mesh with the annular gear ring;

[0016] A power unit is installed inside the coffee machine. The output shaft of the power unit is equipped with a drive gear, which is used to mesh with the driven gear.

[0017] A coffee powder dispenser, characterized in that it includes a handle and a coffee powder dispensing assembly as described in any of the above embodiments, one end of the handle has a cavity, the upper opening of the cavity forms a powder receiving port, the lower opening of the cavity forms a powder dispensing port, the coffee powder dispensing assembly is disposed in the cavity, the upper opening of the powder dispensing tube communicates with the powder receiving port, the lower opening of the powder dispensing tube communicates with the powder dispensing port, and the handle is provided with a controller for controlling the start and stop of the power mechanism.

[0018] A coffee machine includes a body and a coffee powder funnel. The body is equipped with a coffee grinder. The coffee machine also includes a coffee powder distribution assembly as described in any of the above embodiments. The coffee powder distribution assembly is located below the powder outlet of the coffee grinder, and the upper end of the powder distribution cylinder is open and opposite to the powder outlet, for receiving coffee powder ground by the coffee grinder.

[0019] Furthermore, the coffee machine also includes a connector and a powder dispenser. The connector is fixed to the machine body and located below the powder outlet of the grinder. The powder dispenser and the powder container are interchangeably mounted on the connector. The coffee powder funnel is detachably mounted on the powder dispenser and at the lower opening of the powder container, respectively. This allows users to easily replace the powder dispenser and powder container as needed, increasing the flexibility of the coffee machine.

[0020] Furthermore, the connector has a connecting cavity, and the powder receiving rack and the powder dispersing cylinder are respectively provided with plug-in parts. The two opposite cavity walls of the connecting cavity are respectively provided with first plug holes, and the plug-in part is provided with a second plug hole. When the plug-in part is inserted into the connecting cavity, the plug-in part and the connector are connected by a plug rod passing through the first plug hole and the second plug hole. This structure is simple and makes it more convenient to replace the powder receiving rack and the powder dispersing cylinder.

[0021] Furthermore, the bottom of the inner circumferential wall of the powder container is provided with multiple arc-shaped grooves, and the outer circumferential wall of the coffee powder funnel is provided with multiple protrusions corresponding to the multiple arc-shaped grooves. When the coffee powder funnel is placed on the powder container, the multiple protrusions are inserted into the arc-shaped grooves one by one. In this way, the coffee powder funnel can be fixed on the powder container without the need for manual support of the coffee powder funnel.

[0022] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0023] The coffee powder distribution assembly of this invention utilizes a powder distribution disc inside a powder distribution cylinder to receive ground coffee powder. Then, a power mechanism drives a scraper to spread the coffee powder on the powder distribution disc and drop it through the powder distribution holes into the powder distribution chamber of the distribution head. As the distribution head rotates, it can evenly distribute the coffee powder through the powder distribution openings on it. This ensures that the coffee powder is evenly distributed and accumulated, thereby avoiding significant channeling during the coffee brewing process and improving the quality of the coffee.

[0024] The coffee powder dispenser of this invention can replace the method of pre-treating coffee powder piles with a "powder needle". The coffee powder dispenser component is set in a cavity at one end of the handle, and the handle is equipped with a control board that can control the start and stop of the power mechanism. This coffee powder dispenser is easy to operate and convenient to use for baristas and ordinary coffee lovers.

[0025] In this embodiment of the invention, the coffee machine places the coffee powder distribution component below the coffee grinder's outlet. This allows the ground coffee powder to be dispersed through the powder distribution disc, preventing the coffee powder from piling up or clumping. Finally, the dispersed coffee powder can be evenly spread into the coffee powder funnel through the powder distribution head, forming a uniform coffee powder cake inside. Attached Figure Description

[0054] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0055] Example 1:

[0056] This embodiment provides a coffee powder distribution component, such as... Figure 1 and Figure 2 As shown, the coffee powder distribution assembly mainly includes a powder dispensing cylinder 10, a powder scraper 20, a powder dispensing head 30, and a power mechanism 40.

[0057] The powder tube 10 is vertically arranged and has open ends. Inside the powder tube 10 is a powder tray 11. The outer periphery of the powder tray 11 is connected to the inner wall of the powder tube 10. Powder holes 12 are arranged on the inner wall of the powder tray 11.

[0058] Both the scraper 20 and the powder applicator 30 are disposed inside the powder dispensing cylinder 10. The scraper 20 is rotatably disposed above the powder dispensing disc 11, and the powder applicator 30 is rotatably disposed below the powder dispensing disc 11. The powder applicator 30 is provided with a powder dispensing cavity 300. Figure 3The bottom of the powder head 30 is provided with multiple powder outlets 301 that communicate with the powder cavity 300.

[0059] The power mechanism 40 is used to drive the scraper 20 and the powder distribution head 30 to rotate, so that the coffee powder on the powder tray 11 is dispersed by the scraper 20 and falls into the powder distribution chamber 300 through the powder distribution hole 12, and finally is evenly sprinkled out through the powder distribution port 301.

[0060] In this embodiment, the coffee powder distribution assembly utilizes the powder distribution tray 11 within the powder distribution cylinder 10 to receive the ground coffee powder. The powder scraper 20 spreads the coffee powder on the powder distribution tray 11 and then drops it through the powder distribution hole 12 into the powder distribution chamber 300 of the powder distribution head 30. As the powder distribution head 30 rotates, it can evenly distribute the coffee powder through the powder distribution port 301 provided on it. This ensures that the coffee powder after being distributed and accumulated is uniform, thereby avoiding obvious channeling effects during the coffee brewing process and improving the quality of the coffee.

[0061] The coffee powder distribution component in this embodiment can be used with the coffee powder funnel 80, such as... Figure 7 As shown, the top opening of the powder dispenser 10 can receive coffee powder flowing from the grinder, and the bottom of the powder dispenser 10 can be connected to the coffee powder funnel 80. The coffee powder funnel 80 usually has a filter screen 800 inside. When the coffee powder funnel 80 is installed on the powder dispenser 10, the powder distribution head 30 can extend into the filter screen 800 of the coffee powder funnel 80. Thus, as the powder distribution head 30 rotates, the coffee powder will be evenly distributed in the coffee powder funnel 80.

[0062] like Figure 6 As shown, in some embodiments, the bottom of the inner circumferential wall of the powder container 10 is provided with a plurality of arc-shaped grooves 101, and the outer circumferential wall of the coffee powder funnel 80 is provided with a plurality of protrusions 801 corresponding one-to-one with the plurality of arc-shaped grooves 101. Figure 16 As shown, when the coffee powder funnel 8 is placed on the powder container 10, multiple protrusions 801 are inserted one-to-one into the arc-shaped slots 101. This eliminates the need for the user to hold the coffee powder funnel 80 and ensures the stability of the coffee powder funnel 80 when receiving coffee powder.

[0063] like Figure 2 As shown, in some embodiments, the coffee powder distribution assembly further includes a connecting post 13 for connecting the powder distribution head 30 and the powder scraper 20. The powder distribution tray 11 has a central hole, and the connecting post 13 passes through the central hole. Its top is directly connected to the powder scraper 20, and its bottom extends into the powder distribution cavity 300 and is inserted into the hollow post 303 at the center of the powder distribution cavity 300. Figure 3 This allows the powder-coating head 30 and the powder-scraping plate 20 to rotate synchronously via the connecting column 13.

[0064] In this embodiment, the power mechanism 40 can be connected to the powder scraper 20 or the powder application head 30 to drive the powder scraper 20 and the powder application head 30 to rotate synchronously. Alternatively, the powder scraper 20 and the powder application head 30 can each be equipped with a corresponding power mechanism 40 to drive their rotation, so as to achieve independent rotation of the powder scraper 20 and the powder application head 30.

[0065] like Figure 3 As shown, in some embodiments, the coffee powder dispenser 30 is cylindrical in shape, with its upper surface recessed downwards to form a cylindrical coffee powder cavity 300. The top opening of the coffee powder cavity 300 is located below the coffee powder dispensing hole 12 on the coffee powder tray 11, allowing the coffee powder on the coffee powder tray 11 to fall directly into the coffee powder cavity 300. The top edge of the coffee powder cavity 300 is bent outwards to form an annular platform 302, which fits against the lower surface of the coffee powder tray 11 to ensure that the coffee powder passing through the coffee powder dispensing hole 12 does not fall outside the coffee powder dispenser 30.

[0066] Furthermore, in some embodiments, the lower surface of the powder dispensing tray 11 is provided with a powder sweeping plate 50 extending into the powder dispensing cavity 300. The powder sweeping plate 50 is parallel to the axis of the powder dispensing cavity 300, with its bottom surface close to the bottom surface of the powder dispensing cavity 300 and one side wall of the powder sweeping plate 50 close to the inner wall of the powder dispensing cavity 300. Because the powder dispensing tray 11 is fixed inside the powder dispensing cylinder 10, the powder sweeping plate 50 remains stationary when the powder dispensing head 30 rotates, while the powder dispensing head 30 and the powder sweeping plate 50 rotate relative to each other. In this way, when the powder dispensing head 30 rotates, the powder sweeping plate 50 continuously sweeps the coffee powder in the powder dispensing cavity 300 to the powder dispensing port 301, and then evenly sprinkles it out through the powder dispensing port 301, so as to ensure that there is no excessive accumulation of coffee powder in the powder dispensing cavity 300.

[0067] like Figure 4 As shown, in some embodiments, the number of powder distribution ports 301 in this embodiment is three. These three powder distribution ports 301 are all disposed on the bottom of the powder distribution cavity 300 and are arranged circumferentially along the bottom of the cavity. Each powder distribution port 301 expands from the center of the bottom of the powder distribution cavity 300 towards the inner wall of the powder distribution cavity 300 to form a fan-shaped powder distribution port 301. When the powder sweeping plate 50 sweeps the coffee powder to the powder distribution port 301 and sprinkles it out through the two side edges of the powder distribution port 301, the sprinkled coffee powder can be accumulated layer by layer, and finally a uniform coffee powder cake is formed in the coffee powder funnel 80.

[0068] Of course, the number of powder outlets 301 can be more than three, for example, four or five, which needs to be determined according to the size of the powder head 30.

[0069] like Figure 5As shown, in some embodiments, the scraper plate 20 is a long strip-shaped plate that is perpendicular to the upper surface of the powder tray 11. The top of the connecting post 13 can be directly connected to the middle position of the scraper plate 20. In this way, when the scraper plate 20 rotates, it can scrape the coffee powder on the powder tray 11 at both ends simultaneously, thereby improving the scraping efficiency.

[0070] Furthermore, the bottom edge of the scraper 20 is comb-shaped, so that when the scraper 20 rotates, it can scrape apart clumps of coffee powder through the comb-shaped edge at the bottom, thus making it easier for coffee powder to pass through the powder dispersing hole 12.

[0071] Of course, the bottom edge of the scraper 20 in this embodiment can also be serrated, which can also break up clumps of coffee powder.

[0072] like Figure 1 As shown, in some embodiments, the power mechanism 40 for driving the powder scraper 20 and the powder distribution head 30 to rotate mainly includes a rotating frame 400, a driven gear 401, a driving gear 402, and a first drive motor 403.

[0073] A rotating frame 400 is disposed inside the powder dispensing cylinder 10. The rotating frame 400 can be cylindrical, and an annular toothed ring is provided on the outer peripheral wall of the rotating frame 400. A powder scraper 20 is disposed inside the rotating frame 400. The two ends of the powder scraper 20 are respectively fixedly connected to the rotating frame 400, or the powder scraper 20 is integrally disposed with the rotating frame 400. The rotating frame 400 is coaxially disposed with the powder dispensing cylinder 10. When the rotating frame 400 rotates, it can drive the powder scraper 20 to rotate.

[0074] Driven gear 401 is rotatably mounted on powder cylinder 10 via bolt 102. One part of driven gear 401 extends into powder cylinder 10 and meshes with an annular gear ring on rotating frame 400, while the other part extends out of powder cylinder 10 and meshes with drive gear 402. Drive gear 402 is controlled to rotate by first drive motor 403 to drive powder scraper 20 and powder distribution head 30 to rotate synchronously.

[0075] It should be noted that, in this embodiment, the driving gear 402 and the first drive motor 403 can be fixed to a base or bracket with the powder container 10 to form an independent mechanism. Alternatively, the driving gear 402 and the first drive motor 403 can be separate components from the powder container 10. For example, the first drive motor 403 can be fixed to a coffee machine or coffee grinder. When the powder container 10 is fixed to the coffee machine or coffee grinder, the driven gear 401 can mesh with the driving gear 402.

[0076] Example 2:

[0077] like Figures 8-9As shown, this embodiment provides a coffee powder dispenser, which includes a coffee powder dispensing component as described in Embodiment 1 and a handle 60.

[0078] One end of the handle 60 is provided with a cavity 600, which extends through the upper and lower surfaces of the handle 60. The upper opening of the cavity 600 forms a powder receiving port, and the lower opening of the cavity 600 forms a powder dispensing port. The coffee powder dispensing assembly is installed in the cavity 600. The upper opening of the powder dispensing tube 10 is connected to the powder receiving port, and the lower opening of the powder dispensing tube 10 is connected to the powder dispensing port. The handle 60 is provided with a control board 602 that controls the start and stop of the power mechanism 40.

[0079] like Figure 10 As shown, in this embodiment, the lower opening of the cavity 600 on the handle 60 can be connected to the coffee powder funnel 80. After the coffee cup pours the ground coffee powder inside into the cavity 600 through the upper opening, the coffee powder is redistributed by the coffee powder distribution component inside the cavity 600 and then evenly sprinkled into the coffee powder funnel 80.

[0080] like Figure 9 As shown, in some embodiments, a button 604 is provided on the handle 60 near the cavity 600. This button 604 is electrically connected to the control board 602. When holding the handle 60, the user can control the start or stop of the coffee powder dispensing assembly by pressing the button 604, which is convenient for the user. A second drive motor 601 is provided inside the handle 60. The second drive motor 601 is connected to the drive gear 402 in the power mechanism 40 to drive the powder scraper 20 and the powder dispensing head 30 to rotate. The second drive motor 601 is also connected to the control board 602.

[0081] like Figure 8 As shown, the coffee powder dispenser in this embodiment is also equipped with a battery pack that is electrically connected to the second drive motor 601 and the control board 602. The handle 60 is equipped with a socket that is electrically connected to the battery pack. When the battery pack is low on power, a power cord can be plugged into the socket to charge it.

[0082] Example 3:

[0083] This embodiment provides a coffee machine, such as Figure 11 and Figure 12 As shown, the coffee machine includes a body 70, a coffee powder funnel 80, and the coffee powder distribution assembly described in Embodiment 1.

[0084] like Figure 13As shown, the machine body 70 is equipped with a coffee grinder 703, which is used to grind coffee beans into coffee powder. The coffee grinder 703 has a powder outlet channel 704. The coffee powder distribution component is located below the powder outlet of the powder outlet channel 704, and the upper opening of the powder distribution cylinder 10 is opposite to the powder outlet of the coffee grinder 703 to receive the coffee powder after grinding by the coffee grinder 703. When grinding coffee powder, the coffee powder funnel 80 can be placed or fixed in the lower opening of the powder distribution cylinder 10, so that the ground coffee powder is evenly distributed in the filter screen inside the coffee powder funnel 80.

[0085] like Figure 13 As shown, in this embodiment, the grinder 703 is installed inside the machine body 70. The top of the grinder 703 is connected to the coffee bean hopper 700, which is installed outside the machine body 70. The coffee bean hopper 700 contains coffee beans that need to be ground. When the coffee machine is working, the coffee beans continuously enter the grinder 703 to be ground into coffee powder.

[0086] The internal structure of the coffee grinder 703 is existing technology and is not within the scope of protection of this invention, so it will not be described in detail here.

[0087] In some embodiments, the coffee machine body 70 is also provided with a brewing head 701 on the side of the coffee powder distribution assembly. The body 70 is provided with a water tank and a hot water pipe connecting the water tank and the brewing head 701. After the user holds the coffee powder funnel 80 and fills the bottom of the powder container 10 with coffee powder, the coffee powder funnel 80 can be placed at the bottom of the brewing head 701. At the same time, a coffee cup is placed at the bottom of the coffee powder funnel 80. The brewing head 701 is activated to allow hot water to flow through the coffee powder inside the coffee powder funnel 80, thereby making coffee.

[0088] like Figure 14 As shown, in some embodiments, the coffee machine body 70 is also provided with a connector 705, which is located below the powder outlet of the grinder 703. The connector 705 can be replaced with a conventional powder holder 707 and the powder dispensing canister 10 in Embodiment 1, so as to improve the flexibility of the coffee machine.

[0089] Specifically, such as Figure 15 As shown, when the user does not need to use the coffee powder distribution component, the powder receiving rack 707 can be installed on the connector 705, and the coffee powder funnel 80 can be placed directly on the powder receiving rack 707 to directly receive the coffee powder ground in the grinder 703. At this time, the user can stir the coffee powder in the coffee powder funnel 80 to make the coffee powder pile dispersed and even.

[0090] like Figure 16As shown, when the user needs to use the coffee powder distribution assembly, the powder receiving rack 707 can be removed, the powder dispensing tube 10 can be installed on the connector 705, and the coffee powder funnel 80 can be installed on the powder dispensing tube 10. The coffee powder distribution assembly will automatically and evenly distribute the ground coffee powder into the coffee powder funnel 80.

[0091] To enable the powder receiving rack 707 and the powder dispensing cylinder 10 to be detachably mounted on the connector 705, such as Figure 14 As shown, in some embodiments, the connector 705 is provided with a connection cavity, and a first insertion hole 706 is provided on two opposite cavity walls of the connection cavity.

[0092] Furthermore, such as Figure 17 and Figure 2 As shown, the powder receiving rack 707 and the powder dispensing cylinder 10 are respectively provided with plug-in portions 100 adapted to the connecting cavity. The plug-in portion 100 can be inserted into the connecting cavity. The plug-in portion 100 is provided with a second insertion hole 708. When the plug-in portions 100 of the powder receiving rack 707 and the powder dispensing cylinder 10 are respectively inserted into the connecting cavity of the connector 705, the plug rod 709 can pass through the first insertion hole 706 and the second insertion hole 708 to fix the powder receiving rack 707 or the powder dispensing cylinder 10 onto the connector 705. Figure 15 and Figure 16 As shown. This structure is simple and facilitates the replacement of the powder receiving rack 707 and the powder dispensing tube 10.
