Description

Technical Field

[0001] This application belongs to the field of coffee making technology, and in particular relates to a side-drive brewing component and a coffee machine. Background Technology

[0002] In existing semi-automatic pressure coffee machines, the coffee grounds need to be collected using a funnel assembly, weighed to a specified amount, manually tamped down, and then loaded onto the funnel holder. This method is cumbersome and results in uneven pressure distribution on the coffee grounds, leading to insufficient extraction pressure, incomplete extraction, or brewing failure.

[0003] To address the problems associated with manual tamping in semi-automatic pressure coffee machines, electric tamping pressure coffee machines have emerged. However, existing electric tamping machines are generally direct-drive types, which at least have the problem of excessively large vertical dimensions. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a side-drive brewing assembly and coffee machine that is smaller in size and more compact in structure.

The double gear includes a gear portion and a worm gear portion coaxially arranged and fixedly connected. The gear portion meshes with the driven gear, and the worm gear portion meshes with the output shaft of the motor. The structure is reasonable, and by providing a double gear with a worm gear portion, it is easy to change the direction of the force output by the motor, allowing the motor to be positioned laterally and located on one side of the top cover assembly.

[0013] In an optional embodiment, the outer periphery of the base shell abuts against the outer periphery of the transmission sleeve. The two sides of the abutment point of the base shell and the transmission sleeve are connected by intersecting horizontal and vertical ribs. The extending direction of the horizontal ribs is parallel to the plane defined by the axis of the base shell and the axis of the transmission sleeve, and the distance between the outermost rib and the axis of the base shell is less than the radius of the base shell. This allows the base shell and the transmission sleeve to be firmly and tightly joined together, improving the stability of the structure.

[0014] In an optional embodiment, the shape of the funnel support is adapted to the shape of the connected base shell and the transmission screw sleeve, and surrounds both the base shell and the transmission screw sleeve; and / or

[0015] The bottom end of the funnel support is partially closed corresponding to the transmission screw sleeve and is provided with a positioning part. At least the lower end of the transmission screw is hollow, and the positioning part extends into the hollow. The bottom end of the funnel support, corresponding to the base shell, has a powder-feeding port communicating with the inner cavity of the funnel support. The powder-feeding port has a funnel interface protruding downwards from the bottom end of the funnel support. The funnel interface is used for detachably installing the funnel assembly. This ensures smooth rotation of the transmission screw and ease of installation of the funnel assembly.

[0016] In an optional embodiment, the funnel support is provided with a guide rib extending vertically on the inner surface of the transmission screw sleeve; the outer circumferential surface of the transmission screw sleeve is provided with a guide groove extending axially, and the guide rib is provided in the guide groove so that when the transmission screw sleeve moves up and down, the guide rib slides along the guide groove to ensure smooth operation.

[0017] In an optional embodiment, the brewing body has an annular outer peripheral surface, and a sealing ring is provided on the outer peripheral surface; when the brewing head assembly moves downward to the point where the brewing body extends into the funnel interface, the sealing ring is tightly fitted with the inner wall surface of the funnel interface, so as to form a sealed space inside the funnel assembly, ensuring extraction pressure and extraction effect.

[0018] In an optional embodiment, the funnel support is provided with a powder inlet corresponding to the brewing head, and a powder channel is connected to the powder inlet so that when the brewing head assembly moves upward to avoid the funnel assembly, powder is fed into the funnel assembly through the powder inlet.

[0019] A coffee machine includes a body, a grinding assembly and a water supply assembly disposed on the body, and a side-drive brewing assembly in any of the above embodiments. The grinding assembly is connected to the funnel support and is used to feed coffee powder to the funnel assembly installed at the bottom of the funnel support. The water supply assembly is connected to the brewing head assembly and is used to provide brewing water to the brewing head assembly.

[0043] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0044] This application provides a side-drive brewing assembly that can be used in a fully automatic pressure coffee machine for brewing coffee.

[0045] like Figures 1 to 6 As shown, the side-drive brewing assembly includes a funnel support 1, a brewing head assembly 3, and a drive mechanism. The funnel assembly 8 is detachably mounted on the bottom end of the funnel support 1, and a top cover assembly 2 is provided on the top end. The top cover assembly 2 and the funnel support 1 cooperate to form a chamber. The brewing head assembly 3 is located within the chamber and includes a brewing head 31 and a transmission component fixed to the side of the brewing head 31, i.e., the brewing head 31 and the transmission component are arranged side-by-side. The drive mechanism is located on the top cover assembly 2 and is at least used to drive the transmission component to move the brewing head 31 downwards within the chamber, so that the lower end face of the brewing head 31 abuts against the powder inside the funnel assembly 8 and compacts the powder.

[0046] The brewing head 31 of the side-drive brewing assembly in this embodiment can tamp the coffee powder and maintain zero distance from the powder in the funnel assembly 8 to ensure stable extraction pressure and improve the tamping effect and coffee extraction effect. Moreover, since the side drive method is adopted, the space occupied above the brewing head assembly 3 can be reduced, so that the vertical dimension of the side-drive brewing assembly can be reduced, thereby reducing the overall size of the coffee machine using the side-drive brewing assembly.

[0047] In some embodiments, such as Figure 3As shown, the brewing head 31 includes a cylindrical base shell 311 and a brewing body 312 fixed and sealed at the bottom end of the base shell 311. When the brewing body 312 is fixed at the bottom end of the base shell 311, at least its lower end face protrudes from the bottom end of the base shell 311, so that the lower end face of the brewing body 312 can act on the powder in the funnel assembly 8 and compact it. The transmission component includes a transmission sleeve 32 fixed to the side of the base shell 311. The axis of the transmission sleeve 32 is parallel to the axis of the base shell 311, that is, the transmission sleeve 32 is arranged side by side with the housing. Using the transmission sleeve 32, which is arranged side by side with the base shell 311, as the transmission component facilitates the smooth and stable movement of the base shell 311 and the brewing body 312 on it. Moreover, the brewing head 31 can not only compact the powder, but also maintain zero distance from the coffee powder 10 in the funnel assembly 8, thus maintaining the stability of the extraction pressure.

[0048] Furthermore, a transmission screw 4, threadedly connected to the transmission screw sleeve 32, is threaded through the transmission screw sleeve 32. The transmission screw 4 is driven by the drive mechanism to rotate, causing the transmission screw sleeve 32 and the brewing head 31 to move up and down along the transmission screw 4. The power of the drive mechanism is transmitted to the transmission screw sleeve 32 through the transmission screw 4. The structure is simple, easy to implement, and has a good force transmission effect.

[0049] like Figure 4 As shown, the drive mechanism includes a motor 5, and the output shaft 51 of the motor 5 is provided with helical teeth. The top cover assembly 2 is provided with a driven gear 6 and a double gear 7. The upper end of the transmission screw 4 extends into the top cover assembly 2 and is fixedly connected to the driven gear 6 (see...). Figure 7 The double gear 7 includes a gear section 71 and a worm gear section 72 coaxially arranged and fixedly connected. The gear section 71 meshes with the driven gear 6, and the worm gear section 72 meshes with the output shaft 51 of the motor 5. In this way, the power of the motor 5 is transmitted to the transmission screw 4, causing the transmission screw 4 to rotate. The transmission screw 4 then drives the transmission sleeve 32 and the brewing head 31 fixed to the transmission sleeve 32 to move up and down along the axial direction of the transmission screw 4. This allows the brewing head 31 to move upward to disengage from and avoid the funnel assembly 8, facilitating the filling of powder into the funnel assembly 8, and also allows the brewing head 31 to move downward to press against the powder inside the funnel assembly 8 and compact the powder. This transmission structure is reasonable, and by setting the double gear 7 with the worm gear section 72, it is easy to change the direction of the force output by the motor 5, allowing the motor 5 to be arranged laterally and located on one side of the top cover assembly 2, avoiding the occupation of vertical space and the increase of vertical dimensions.

[0050] Understandably, by using motor 5 as the drive mechanism, the forward and reverse rotation of motor 5 can drive the transmission screw 4 to rotate in both directions, thereby causing the brewing head assembly 3 to move up and down reciprocally. This allows the brewing head assembly 3 to compact and flatten the powder in the funnel assembly 8. Furthermore, by detecting changes in the rotational speed of motor 5, the degree of compaction of the powder (e.g., coffee powder 10) can be obtained, enabling control of the tamping force and ensuring extraction effect and taste.

[0051] In some embodiments, such as Figure 3 As shown, the outer periphery of the base shell 311 abuts against the outer periphery of the transmission sleeve 32. The two sides of the abutment point of the base shell 311 and the transmission sleeve 32 are connected by intersecting horizontal and vertical ribs 33. The extension direction of the horizontal ribs 33 is parallel to the plane defined by the axis of the base shell 311 and the axis of the transmission sleeve 32, and the distance between the outermost rib 33 and the axis of the base shell 311 is less than the radius of the base shell 311. This allows the base shell 311 and the transmission sleeve 32 to be stably and tightly joined together, minimizing the volume of the brewing head assembly 3 and facilitating miniaturization.

[0052] It is understandable that the base shell 311 and the transmission screw sleeve 32 can also adopt an integrated structure to further increase the stability of the structure and the consistency of their lifting.

[0053] In some embodiments, such as Figure 5 and Figure 6 As shown, the shape of the funnel support 1 is adapted to the shape of the base shell 311 and the transmission screw sleeve 32 connected together, and it wraps around both the base shell 311 and the transmission screw sleeve 32. That is, the inner cavity shape of the funnel support 1 is adapted to the shape of the brewing head assembly 3, and its cross-section is approximately racetrack-shaped.

[0054] Continue to combine Figure 5 and Figure 6 The upper end of the funnel support 1 is open and sealed by the top cover assembly 2. The bottom end of the funnel support 1 is partially closed corresponding to the transmission screw sleeve 32 and has a positioning part 12 extending into the lower end of the main transmission screw 4. The positioning part 12 can be a hollow protrusion. To reduce weight, the transmission screw 4 can be a hollow structure. The bottom end of the funnel support 1 has a powder inlet 15 communicating with the inner cavity of the funnel support 1 at the part corresponding to the base shell 311. The bottom end of the funnel support 1 has a funnel interface 11 that mates with the powder inlet 15. The funnel interface 11 protrudes downward from the bottom end of the funnel support 1 and is used for detachably installing the funnel assembly 8. Powder can fall into the funnel assembly 8 through the powder inlet 15.

[0055] like Figure 3As shown, the brewing body 312 has an annular outer circumferential surface with an annular groove, and a sealing ring 314 is embedded in the annular groove. When the brewing head assembly 3 moves downward until the brewing body 312 extends into the funnel inlet 11, the sealing ring 314 fits tightly against the inner wall of the funnel inlet 11, thereby forming a sealed space within the funnel assembly 8. See [reference needed]. Figure 10 .

[0056] In some embodiments, such as Figure 5 As shown, the funnel support 1 has a vertically extending guide rib 13 on the inner surface corresponding to the transmission screw sleeve 32. Figure 3 As shown, the outer circumferential surface of the transmission sleeve 32 is provided with a guide groove 321 extending along its axial direction, and the guide rib 13 is provided in the guide groove 321 so that when the transmission sleeve 32 moves up and down, the guide rib 13 slides along the guide groove 321 to guide the lifting and lowering of the transmission sleeve 32 and ensure the smooth operation.

[0057] In some embodiments, continue to combine Figure 5 The funnel support 1 has a powder inlet 14 on the part corresponding to the brewing head 31, and a powder channel 9 is connected to the powder inlet 14. See Figure 2 , Figure 8 and Figure 10 When the brewing head assembly 3 moves upward under the action of the drive mechanism to avoid the funnel assembly 8, powder can be fed into the funnel assembly 8 through the powder inlet 14.

[0058] The top cover assembly 2 includes an upper cover 21 and a lower cover 22. The upper cover 21 is fastened to the lower cover 22 to form a cavity for accommodating and protecting the driven gear 6, the double gear 7 and the output shaft 51 of the motor 5.

[0059] This application also provides a coffee machine, which includes a body, a grinding assembly and a water supply assembly disposed on the body, as well as a side-drive brewing assembly in any of the above embodiments. The grinding assembly is connected to the funnel support 1 and is used to feed powder to the funnel assembly 8 installed at the bottom of the funnel support 1. The water supply assembly is connected to the brewing head assembly 3 and is used to provide brewing water to the brewing head assembly 3.

[0060] The coffee machine of this application uses side-drive to combine tamping and brewing. The tamping is performed by the up-and-down movement of the brewing head 31, ensuring stable extraction pressure regardless of the amount of coffee grounds in the funnel assembly 8. Furthermore, there is no need to replace the single or double cup funnel filters 81 within the funnel assembly 8; a double cup funnel filter 81 can be used for both single and double cup brewing, simplifying operation and reducing costs. Moreover, since side-drive tamping is much smaller than direct-drive tamping, the coffee machine of this application is compact and has broad market prospects in the small appliance sector.

[0061] The following uses coffee brewing as an example to explain the working process and working principle of this application:

[0062] First, insert the funnel filter 81 into the funnel assembly 8, and then attach it together to the funnel inlet 11 at the bottom of the funnel support 1 (see...). Figure 8 and Figure 10 At this time, the brewing head assembly 3 is positioned above the transmission screw 4, avoiding the powder inlet on the funnel support 1. (See below) Figure 7 and Figure 8 .

[0063] The coffee machine's grinding assembly is activated to grind coffee beans. Coffee powder 10 flows from the powder inlet 91 to the powder outlet 92 of the powder channel 9, and then falls into the funnel filter 81 through the powder outlet 15 of the funnel holder 1. After grinding, the motor 5 is activated. The motor 5 drives the transmission screw 4 to rotate through its output shaft 51, double gear 7, and driven gear 6, which in turn drives the transmission sleeve 32 to move downwards. The brewing head 31 moves downwards synchronously with the transmission sleeve 32. (See [link to relevant documentation]). Figure 9 The vertical movement of the brewing head 31 forms an automatic "coffee hammer." Because the brewing head 31 can move up and down, it can precisely compress or loosen the coffee powder 10 in the funnel filter 81 according to the amount of coffee powder in the funnel filter 81, in conjunction with the motor 5, until the coffee powder 10 in the funnel filter 81 is flattened to 10-20 kgf. (See [link to relevant documentation]). Figure 10 Meanwhile, the sealing ring 314 on the outer periphery of the brewing head 31 fits tightly against the inner peripheral wall of the funnel interface 11, forming a seal inside the funnel filter 81. Then, the heating boiler of the coffee machine's water supply assembly starts working and outputs hot water to the water inlet 313 (connected to the heating boiler) of the brewing head 31 to soak the coffee powder 10 inside the funnel filter 81. Due to the presence of the sealing ring 314, a pressurized sealed space is formed inside the funnel filter 81, and the brewed coffee liquid flows out from the funnel filter 81 and is provided to the user for drinking.

[0064] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
