Description

Technical Field

[0001] This disclosure relates to the technical field of coffee brewing, and in particular to a coffee brewing device, brewing method, system, computer device, and storage medium thereof. Background Technology

[0002] Currently, the coffee consumption market continues to expand, and consumers' pursuit of beverage flavor has driven the popularization of pour-over coffee. To meet the convenient brewing needs of home, office, and other scenarios, pour-over coffee machines with automatic operation functions have become a key focus of industry research and development and market layout. For example, a pour-over coffee machine disclosed in existing technology patent CN117958597A includes a rotating tank body, a water tank disposed on the rotating tank body, and a control device. The rotating tank body is provided with a water spout with an adjustable angle, which is connected to the water tank through a water circuit system. The rotating tank body is also provided with a drive device electrically connected to the control device, a transmission structure connected to the drive device, and a pusher. The transmission structure and the pusher are disposed above the water spout. The drive device drives the transmission structure to push the pusher to move up and down above the water spout to change the tilt angle of the water spout in the vertical direction.

[0003] However, the pour-over coffee machine disclosed in the aforementioned patent still has significant technical defects in practical applications, making it difficult to meet the core requirement of uniform extraction for specialty coffee. Specifically, the water injection method achieved by changing the tilt angle of the spout can essentially only form a single spiral water injection trajectory. This injection mode causes the water flow to mainly concentrate on rinsing a specific annular area of ​​the coffee puck, failing to achieve precise and sufficient water coverage for the periphery and center of the coffee puck. The periphery is prone to under-extraction due to insufficient water injection, while the center is prone to insufficient extraction due to the difficulty of water penetration, even leading to a coexistence of local over-extraction and under-extraction, thus significantly reducing the extraction quality and taste stability of pour-over coffee. Summary of the Invention

[0027] A computer device includes a memory and a processor.

A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the brewing method described in any of the above embodiments.

[0028] Compared with the prior art, this disclosure has at least the following advantages: In the aforementioned coffee brewing device, when the first and second threaded parts are screwed together, the pushing end of the pushing component slides towards or away from the deflector nozzle holder to adjust the deflection angle of the deflector nozzle holder relative to the rotating tank. Specifically, as the pushing end of the pushing component moves towards the deflector nozzle holder, it gradually increases the resistance force on the deflection area of ​​the deflector, thus gradually increasing the deflection angle of the deflector nozzle holder relative to the rotating tank. Conversely, as the pushing end of the pushing component moves away from the deflector nozzle holder, it gradually decreases the resistance force on the deflection area of ​​the deflector, allowing the elastic water pipe to reset through its own elasticity. This causes the deflection angle of the deflecting nozzle holder relative to the rotating tank to gradually decrease, resulting in a spiral water outlet trajectory. This achieves a spiral water injection of the coffee puck into the coffee brewing equipment, allowing the water flow to accurately cover and penetrate the central annular area of ​​the coffee puck. When the pushing end of the pushing component slides towards the deflecting nozzle holder until the second threaded part moves to the first preset position of the water outlet, the second threaded part disengages from the first threaded part and is in the idle zone. At this time, the compression of the elastic support is at its maximum. The elastic pushing component supports the transmission seat through its own elastic thrust, keeping the top end face of the second threaded part in close sliding contact with the bottom end face of the first threaded part, thus limiting the second threaded part to the idle zone. The device rotates in the rotating zone and idles in the idle zone, allowing the pushing end of the pushing component to press against the deflecting nozzle holder with maximum resistance. The deflecting nozzle holder maintains its maximum deflection angle, resulting in a circular water output trajectory from the nozzle. This achieves a circular, surrounding water injection of the coffee puck into the coffee brewing equipment, ensuring precise water coverage and penetration of the periphery of the coffee puck. When the pushing end of the pushing component slides away from the deflecting nozzle holder until the second threaded part moves to the second preset position of the water outlet, the resistance between the pushing end of the pushing component and the deflecting part becomes zero. This allows the deflecting nozzle holder to return to its initial state through the elasticity of the elastic water pipe, aligning the center line of the connecting hole with the central axis of the rotating tank. The lines are on the same straight line, and the drive end of the drive control component stops driving the rotating tank so that the deflection angle of the deflection nozzle holder is zero, so that the water outlet output has a single-point water trajectory in the center, realizing the single-point water injection of the coffee powder into the center of the coffee brewing equipment, so that the water flow can accurately cover and penetrate the center area of ​​the coffee powder; at the same time, when the drive end of the drive control component drives the second threaded part to idle in the idle area, it is only necessary to control the drive control component to drive the second threaded part to rotate in the first rotation direction, and the second threaded part can be threadedly connected to the first threaded part by the support and pushing action of the elastic support member, so as to change the water outlet output trajectory from a circular shape to a spiral shape;When the second threaded part is located in the second preset position of the water outlet, it is only necessary to control the drive control component to drive the second threaded part to rotate in the second rotation direction. The pushing end of the push component can then overcome the elastic support performance of the elastic support member through the screw connection between the first threaded part and the second threaded part and move towards the deflection nozzle bracket, so as to change the water outlet trajectory from a single point in the center to a spiral shape. Compared with the existing hand-drip coffee machines, which can only achieve a single spiral water pouring method, the coffee brewing device disclosed herein can flexibly switch and operate independently of three water pouring methods: single point in the center, spiral, and circular. It can accurately and fully cover the central area, the central annular area, and the peripheral boundary of the coffee puck with water, effectively avoiding the problems of insufficient extraction, over-extraction, and under-extraction, greatly improving the extraction uniformity of the coffee puck, and thus greatly improving the extraction quality and taste stability of the coffee, thereby greatly improving the user experience.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 11As shown, a coffee brewing device 10 of one embodiment includes a brewing body 100 and a water injection mechanism 200; the water injection mechanism 200 includes a rotating tank 210, a pushing component 220, a deflecting nozzle holder 230, and a drive control component 240. The rotating tank 210 is rotatably mounted on the brewing body 100. The rotating tank 210 has, from top to bottom, a communicating clearance hole 211, a mounting cavity 212, and a water outlet 213. The water outlet portion 110 of the brewing body 100 passes through the clearance hole 211 and extends into the mounting cavity 212. The outer peripheral wall of the water outlet portion 110 has a first threaded portion 111. The pushing component 220 has a threaded portion 111 connected to the water outlet portion 111. A threaded drive hole 221 is provided opposite to the first threaded portion 111. The inner circumferential wall of the threaded drive hole 221 forms a second threaded portion 2211 that is adapted to the first threaded portion 111, so that the water outlet portion 110 is threadedly connected to the push assembly 220. The push assembly 220 is movably disposed in the mounting cavity 212, and there is a circumferential limiting fit between the push assembly 220 and the rotating tank 210, so that the push assembly 220 slides relative to the rotating tank 210 along the axial direction of the water outlet portion 110. The deflection portion 231 of the deflection nozzle holder 230 is disposed in the mounting cavity 212 and located below the push assembly 220. The water outlet 232 of the deflection nozzle holder 230 passes through the water outlet hole 213. Extending beyond the rotating tank 210, the pushing end of the pushing component 220 is positioned opposite to the deflection area 2312 of the deflection section 231; the drive control component 240 is mounted and fixed on the brewing body 100, and the driving end of the drive control component 240 is used to drive the rotating tank 210 to rotate relative to the brewing body 100; the coffee brewing device 10 also includes a flexible water supply pipe 250, the deflection section 231 has a connecting hole 2311 that communicates with the water outlet 232, the water receiving end of the flexible water supply pipe 250 is connected to the water outlet end of the water outlet section 110, and the water outlet end of the flexible water supply pipe 250 passes through the connecting hole 2311 and partially extends to the water outlet 232. Inside 32; an idle area 112 is formed on the outer peripheral wall of the water outlet 110 near the deflection nozzle frame 230, and an elastic support member 260 is also provided between the push assembly 220 and the deflection nozzle frame 230. The two ends of the elastic support member 260 are elastically supported on the push assembly 220 and the deflection nozzle frame 230 respectively. When the first threaded part 111 and the second threaded part 2211 are screwed together and driven, the push end of the push assembly 220 slides towards or away from the deflection nozzle frame 230 to adjust the deflection angle of the deflection nozzle frame 230 relative to the rotating tank 210, so that the water outlet 232 outputs a spiral water trajectory.When the pushing end of the pushing component 220 slides towards the deflecting nozzle holder 230 until the second threaded portion 2211 moves to the first preset position of the water outlet 110, the second threaded portion 2211 disengages from the first threaded portion 111 and is located in the idle zone 112. The second threaded portion 2211 and the idle zone 112 then idle together, maximizing the compression of the elastic support member 260. This causes the pushing end of the pushing component 220 to press against the deflecting nozzle holder 230 with maximum holding force, thus maintaining the deflecting nozzle holder 230 at its maximum deflection angle. The water outlet 232 outputs a water trajectory in a circular shape. When the pushing end of the pushing component 220 slides away from the deflecting nozzle holder 230 until the second threaded portion 2211 moves to the second preset position of the water outlet 110, the center line of the connecting hole 2311 and the center axis of the rotating tank 210 are on the same straight line, and the driving end of the drive control component 240 stops driving the rotating tank 210, so that the deflection angle of the deflecting nozzle holder 230 is zero, resulting in the water outlet 232 outputting a water trajectory in a single-point center shape.

[0036] In the aforementioned coffee brewing device 10, when the first threaded portion 111 and the second threaded portion 2211 are screwed together, the pushing end of the pushing component 220 slides towards or away from the deflection nozzle holder 230 to adjust the deflection angle of the deflection nozzle holder 230 relative to the rotating tank 210. Specifically, as the pushing end of the pushing component 220 moves towards the deflection nozzle holder 230, the pushing end of the pushing component 220 gradually increases the supporting force on the deflection area 2312 of the deflection portion 231, causing the deflection angle of the deflection nozzle holder 230 relative to the rotating tank 210 to gradually increase; while as the pushing end of the pushing component 220 moves away from the deflection nozzle holder 230, the pushing end of the pushing component 220 gradually decreases the supporting force on the deflection area 2312 of the deflection portion 231, causing the deflection angle of the deflection nozzle holder 230 to gradually increase. The resistance force of the deflection area 2312 of the rotating part 231 allows the elastic water pipe 250 to reset through its own elasticity, causing the deflection angle of the deflection nozzle holder 230 relative to the rotating tank 210 to gradually decrease. This results in the water outlet 232 outputting a spiral water trajectory, achieving spiral water injection of the coffee brewing device 10 onto the coffee puck, thus ensuring that the water flow accurately covers and penetrates the central annular area of ​​the coffee puck. When the pushing end of the pushing component 220 slides towards the deflection nozzle holder 230 until the second threaded part 2211 moves to the first preset position of the water outlet 110, the second threaded part 2211 disengages from the first threaded part 111 and is located in the idle area 112, and the compression amount of the elastic support member 260... At its maximum, the elastic pusher 224 supports the transmission seat 222 with its own elastic thrust, causing the top end face of the second thread 2211 to slide and abut against the bottom end face of the first thread 111, so that the second thread 2211 is limited to the idle area 112 and idles in the idle area 112. This causes the pushing end of the pusher assembly 220 to press the deflecting nozzle holder 230 with the maximum holding force. The deflecting nozzle holder 230 maintains the maximum deflection angle, so that the water outlet 232 outputs a water trajectory in a circular shape, realizing the circular water injection of the coffee brewing device 10 to the coffee puck, thereby enabling the water flow to accurately cover and penetrate the peripheral boundary area of ​​the coffee puck. When the pushing end of the pusher assembly 220 moves away from the deflecting nozzle holder 230... The direction slides until the second threaded part 2211 moves to the second preset position of the water outlet part 110. When the pushing end of the pushing component 220 and the deflecting part 231 are at zero, the deflecting water nozzle bracket 230 can be reset to the initial state through the elastic performance of the elastic water supply pipe 250. The center line of the connecting hole 2311 and the center axis of the rotating tank 210 are on the same straight line. The driving end of the drive control component 240 stops driving the rotating tank 210, so that the deflection angle of the deflecting water nozzle bracket 230 is zero. The water outlet 232 outputs a central single-point water trajectory, realizing the central single-point water injection of the coffee brewing device 10 to the coffee powder cake, so that the water flow can accurately cover and penetrate the central area of ​​the coffee powder cake.Simultaneously, when the drive end of the drive control component 240 drives the second threaded portion 2211 to idle in the idle zone 112, it is only necessary to control the drive control component 240 to drive the second threaded portion 2211 to rotate in the first rotation direction. The second threaded portion 2211 can then be threadedly connected to the first threaded portion 111 by the support and pushing action of the elastic support member 260, so as to change the water outlet trajectory of the water outlet 232 from a circular shape to a spiral shape. When the second threaded portion 2211 is located in the second preset position of the water outlet 110, it is only necessary to control the drive control component 240 to drive the second threaded portion 2211 to rotate in the second rotation direction. The pushing end of the push component 220 can then overcome the screw connection between the first threaded portion 111 and the second threaded portion 2211. The elastic support 260 moves towards the deflecting nozzle holder 230, changing the water outlet trajectory of the nozzle 232 from a single-point center shape to a spiral shape. Compared to existing pour-over coffee machines that can only achieve a single spiral pouring method, the coffee brewing device 10 disclosed herein allows for flexible switching and independent operation of three pouring methods: single-point center, spiral, and circular. It can precisely and fully cover the central area, the central annular area, and the peripheral boundary of the coffee puck, effectively avoiding the problems of insufficient extraction, over-extraction, and under-extraction. This significantly improves the extraction uniformity of the coffee puck, thereby greatly enhancing the extraction quality and taste stability of the coffee, and thus greatly improving the user experience.

[0037] like Figure 1 As shown, in this embodiment, the rotating tank 210 is rotatably connected to the brewing body 100 via a rotating shaft or bushing, so that the rotating tank 210 can rotate relative to the brewing body 100.

[0038] like Figures 1 to 9As shown, in one embodiment, the pushing assembly 220 includes a transmission seat 222 and a pushing frame 223. A threaded transmission hole 221 is formed on the transmission seat 222. The pushing end of the pushing assembly 220 is disposed on the pushing frame 223. The transmission seat 222 is movably disposed at one end of the pushing frame 223 adjacent to the clearance hole 211. The pushing frame 223 and the transmission seat 222 are circumferentially limited to each other, and the pushing frame 223 and the rotating tank 210 are circumferentially limited to each other, so that the pushing frame 223 slides relative to the rotating tank 210 along the axial direction of the water outlet 110. This allows the pushing frame 223 to drive the transmission seat 222 to rotate relative to the water outlet 110 when the rotating tank 210 drives the pushing frame 223 to rotate relative to the water outlet 110, so that the second threaded portion 2211 can rotate relative to the first threaded portion 111. During the movement of the deflector bracket 230, the transmission seat 222 can push the pusher bracket 223 to slide closer to the deflector bracket 230, so that the supporting force between the pusher bracket 223 and the deflection area 2312 of the deflector bracket 230 gradually increases, and the deflection angle of the deflector bracket 230 gradually increases. When the transmission seat 222 moves away from the deflector bracket 230, the elastic support member 260 can push the pusher bracket 223 to slide away from the deflector bracket 230 through its own elastic properties, so that the supporting force between the pusher bracket 223 and the deflection area 2312 of the deflector bracket 230 gradually decreases, and the elastic water pipe 250 can push the deflector bracket 230 to perform a reset operation through its own elastic properties, thereby making the deflection angle of the deflector bracket 230 gradually decrease.

[0039] like Figures 1 to 9 As shown, in one embodiment, the end face of the pusher 223 adjacent to the clearance hole 211 forms a receiving groove 2231. The transmission seat 222 is disposed in the receiving groove 2231 and slides against the inner wall of the receiving groove 2231. The inner peripheral wall of the receiving groove 2231 also has a circumferential limiting fit with the transmission seat 222, so that the pusher 223 can protect the transmission seat 222, effectively reducing the possibility of direct squeezing and collision between external hard objects and the transmission seat 222. At the same time, when the rotating tank 210 drives the pusher 223 to rotate, the pusher 223 can drive the transmission seat 222 to rotate relative to the water outlet 110, thereby greatly improving the service life and operational stability of the coffee brewing equipment 10.

[0040] like Figures 1 to 9As shown, in one embodiment, a first limiting guide flange 2121 protrudes from the top inner wall of the mounting cavity 212, and the pusher frame 223 forms a limiting guide hole 2232 adapted to the first limiting guide flange 2121. The first limiting guide flange 2121 passes through the limiting guide hole 2232 and slides against the hole wall of the limiting guide hole 2232, so that when the rotating tank 210 rotates relative to the water outlet 110, the rotating tank 210 can pass through the circumferential direction of the first limiting guide flange 2121 and the limiting guide hole 2232. The limiting mechanism drives the pusher 223 to rotate relative to the water outlet 110, enabling the pusher 223 to effectively drive the transmission seat 222 to rotate relative to the water outlet 110. When the transmission seat 222 or the elastic support 260 pushes the pusher 223 to slide relative to the rotating tank 210, the pusher 223 can slide along the guiding direction of the first limiting guide flange 2121, allowing the pusher 223 to accurately press the deflection area 2312 of the deflection nozzle holder 230, thereby greatly improving the stability of the coffee brewing equipment 10.

[0041] like Figures 1 to 5 As shown, in one embodiment, the inner peripheral wall of the receiving groove 2231 is provided with a second limiting guide flange 2231a, and the outer peripheral wall of the transmission seat 222 is formed with a first limiting guide groove 2221 adapted to the second limiting guide flange 2231a. The second limiting guide flange 2231a is disposed in the first limiting guide groove 2221 and slides against the inner wall of the first guiding groove. The second limiting guide flange 2231a and the first limiting guide flange 2221 are arranged parallel to each other, so that when the push frame 223 rotates relative to the water outlet 110, the push frame 223 can drive the transmission seat 222 to rotate relative to the water outlet 110 through the circumferential limiting cooperation of the first limiting guide groove 2221 and the second limiting guide flange 2231a, and also enable the transmission seat 222 to rotate relative to the water outlet 110. The transmission seat 222 slides relative to the rotating tank 210 along the guiding direction of the second limiting guide flange 2231a. This causes the direction of the thrust of the transmission seat 222 to be consistent with the sliding direction of the pusher 223 when the transmission seat 222 pushes the pusher 223 relative to the rotating tank 210. This ensures that the transmission seat 222 transmits power linearly throughout the process of pushing the pusher 223, reducing lateral force loss and effectively improving the power transmission efficiency between the transmission seat 222 and the pusher 223. At the same time, the transmission seat 222 can also avoid lateral squeezing force on the pusher 223 due to the deviation of the thrust direction, thereby greatly reducing the possibility of jamming or uneven wear of the pusher 223 during the sliding process relative to the rotating tank 210. This greatly improves the stability and service life of the coffee brewing equipment 10.

[0042] like Figures 1 to 5As shown, in one embodiment, the central axis of the elastic support 260 and the circumferential axis of the deflection nozzle holder 230 are on the same straight line to avoid the deflection area 2312 of the deflection nozzle holder 230 being deflected due to the pressure of the elastic support 260. At the same time, the elastic support 260 can also assist the deflection nozzle holder 230 to return to its initial state through its own elastic properties, further improving the stability of the coffee brewing device 10.

[0043] like Figures 1 to 5 As shown, in one embodiment, the pushing assembly 220 further includes an elastic pushing member 224, which is disposed within the receiving groove 2231. The elastic pushing member 224 is located between the bottom of the receiving groove 2231 and the transmission seat 222. Both ends of the elastic pushing member 224 are elastically supported on the bottom of the receiving groove 2231 and the transmission seat 222, respectively. The elastic pushing member 224 is used to support and push the transmission seat 222 when the second threaded portion 2211 is located within the idle zone 112, so that the elastic pushing member 224 pushes the top end face of the second threaded portion 2211 against the bottom end face of the first threaded portion 111, thereby limiting the second threaded portion 2211 to within the idle zone 112, and the end face of the first threaded portion 111 slides against the end face of the second threaded portion 2211, so that when... When the second threaded portion 2211 is located in the idle zone 112 of the water outlet portion 110, the elastic pusher 224 can use its own elastic properties to push the top end face of the second threaded portion 2211 to abut against and press against the bottom end face of the first threaded portion 111, so that the elastic pusher 224 and the first threaded portion 111 can cooperate with each other to confine the second threaded portion 2211 within the idle zone 112. At the same time, when the rotating tank 210 rotates along the second rotation direction, the second threaded portion 2211 can be screwed onto the first threaded portion 111 under the elastic pushing action of the elastic pusher 224. Moreover, the elastic pusher 224 can also use its own elastic properties to buffer and disperse the squeezing force between the transmission seat 222 and the pusher frame 223, further improving the operational stability of the coffee brewing equipment 10.

[0044] like Figures 1 to 4As shown, in one embodiment, a limiting flange 2231b protrudes from the bottom of the receiving groove 2231. A limiting groove 2222 is formed on one side of the transmission seat 222 adjacent to the elastic pusher 224, which is opposite to and spaced apart from the limiting flange 2231b. One end of the elastic pusher 224 is sleeved on the limiting flange 2231b, and the other end of the elastic pusher 224 is limited in the limiting groove 2222, so that the limiting flange 2231b and the limiting groove 2222 can cooperate with each other to limit both ends of the elastic pusher 224, so that the elastic pusher 224 can be reliably limited to the preset position of the receiving groove 2231, avoiding the phenomenon of the elastic pusher 224 being misaligned or even displaced during the compression process. This makes the direction of the elastic support force of the elastic pusher 224 consistent with the sliding direction of the transmission seat 222, thereby greatly improving the stability of the coffee brewing device 10.

[0045] like Figures 1 to 4 As shown, in one embodiment, there are multiple elastic pushers 224. The multiple elastic pushers 224 are evenly arranged along the outer periphery of the transmission seat 222, which not only makes the transmission seat 222 subject to balanced force, but also increases the elastic support force of the elastic pushers 224 on the transmission seat 222.

[0046] like Figures 1 to 4 As shown, in one embodiment, both the elastic support 260 and the elastic pusher 224 are springs or silicone pads, so that both the elastic support 260 and the elastic pusher 224 have good elastic properties.

[0047] like Figures 1 to 9 As shown, in one embodiment, the contact end of the drive control component 240 is located on the side of the brewing body 100 adjacent to the rotating tank 210, and is positioned opposite to the top of the transmission seat 222 through the clearance hole 211. When the transmission seat 222 slides away from the deflection nozzle bracket 230 to the second preset position of the water outlet 110, the top of the transmission seat 222 abuts against the contact end of the drive control component 240 to control the rotating tank 210 to stop rotating, so that the center line of the connecting hole 2311 and the center axis of the rotating tank 210 are on the same straight line, so that the deflection angle of the deflection nozzle bracket 230 is zero, thereby making the water outlet 232 output a central single-point water trajectory, realizing the central single-point water injection of the coffee brewing device 10 to the coffee powder cake, so that the water flow can accurately cover and penetrate the central area of ​​the coffee powder cake.

[0048] like Figures 1 to 9As shown, in one embodiment, the drive control component 240 includes a drive motor 241 and a reset control board 242. Both the drive motor 241 and the reset control board 242 are mounted and fixed on the brewing body 100. The drive end of the drive control component 240 is located on the drive motor 241. The drive end of the drive motor 241 is provided with a drive gear 2411. A driven gear 214 is sleeved and fixed on the outer peripheral wall of the rotating tank 210. The drive gear 2411 and the driven gear 214 mesh with each other, so that the drive motor 241 drives the rotating tank 210 to rotate relative to the brewing body 100. The contact end of the drive control component 240 is located on the reset control board 242. The contact switch 2421 of the reset control board 242 is set facing the transmission seat 222 and is opposite to the top of the transmission seat 222 through the clearance hole 211. The control end of the reset control board 242 is electrically connected to the control end of the drive motor 241. When the top of the transmission seat 222 abuts against the contact switch 2421, The reset control board 242 is used to control the drive motor 241 to stop driving the rotating tank 210. When the top of the transmission seat 222 comes into contact with the contact switch 2421, the control terminal of the reset control board 242 will transmit a stop signal to the control terminal of the drive motor 241, causing the drive gear 2411 of the drive motor 241 to stop rotating, thereby stopping the rotating tank 210 from rotating. This prevents the top of the transmission seat 222 from continuing to press against the contact switch 2421 after it comes into contact with it. At the same time, when the coffee brewing device 10 completes the brewing operation, the control terminal of the reset control board 242 will control the drive terminal of the drive motor 241 to rotate in the second rotation direction until the top of the transmission seat 222 comes into contact with the contact switch 2421, so that the water injection mechanism 200 can automatically complete the reset operation, so as to facilitate the subsequent brewing operation of the coffee brewing device 10, thereby greatly improving the stability and ease of use of the coffee brewing device 10.

[0049] like Figures 1 to 6As shown, in one embodiment, the pushing component 220 further includes a squeezing plate 225. The brewing body 100 has a mounting hole 120 opposite to the clearance hole 211. The water outlet 110 passes through the mounting hole 120 and the clearance hole 211 in sequence and extends into the mounting cavity 212. The contact switch 2421 is disposed in the mounting hole 120. The squeezing plate 225 is movably limited within the mounting hole 120 and is opposite to the contact switch 2421 of the reset control plate 242. The squeezing plate 225 is circumferentially limited to the hole wall of the mounting hole 120 so that the squeezing plate 225 can slide relative to the hole wall of the mounting hole 120. The squeezing plate 225 is disposed in Between the contact switch 2421 of the reset control board 242 and the top of the transmission seat 222, the top of the transmission seat 222 is used to push the pressing plate 225 to press against the contact switch 2421 of the reset control board 242, so that the pressing plate 225 presses against and triggers the contact switch 2421, so that the transmission seat 222 can indirectly trigger the contact switch 2421 through the pressing plate 225. This effectively avoids direct contact between the transmission seat 222 and the contact switch 2421, and prevents the transmission seat 222 from scratching and wearing the contact switch 2421 during rotation, thereby greatly improving the service life and stability of the contact switch 2421.

[0050] like Figures 1 to 6 As shown, in one embodiment, the outer peripheral wall of the extrusion plate 225 is provided with a second limiting guide groove 2251, and the wall of the mounting hole 120 is provided with a third limiting guide flange 121 that is adapted to the second limiting guide groove 2251. The third limiting guide flange 121 is disposed in the second limiting guide groove 2251 and slides against the inner wall of the second limiting guide groove 2251, so that the second limiting guide groove 2251 and the third limiting guide flange 121 can cooperate with each other to circumferentially limit the extrusion plate 225, preventing the transmission seat 222 from driving the extrusion plate 225 to rotate relative to the water outlet 110. This effectively avoids the extrusion plate 225 from scratching and wearing the contact switch 2421 due to rotation, and further improves the service life of the contact switch 2421. The third limiting guide flange 121 and the second limiting guide flange 2231a are arranged parallel to each other so that the direction of the thrust applied by the transmission seat 222 to the extrusion plate 225 is consistent with the sliding direction of the extrusion plate 225. This allows the transmission seat 222 to transmit the force linearly throughout the process of pushing the extrusion plate 225, reducing lateral force loss and effectively improving the power transmission efficiency between the transmission seat 222 and the extrusion plate 225. At the same time, the transmission seat 222 can also avoid lateral extrusion force on the extrusion plate 225 due to the deviation of the thrust direction, thereby greatly reducing the possibility of jamming or uneven wear of the extrusion plate 225 during the sliding process relative to the hole wall of the mounting hole 120. This greatly improves the stability and service life of the coffee brewing equipment 10.

[0051] like Figures 1 to 6 As shown, in one embodiment, a retaining flange 122 protrudes from one end of the mounting hole 120 adjacent to the clearance hole 211. The retaining flange 122 and the contact switch 2421 of the reset control board 242 together form a limiting area 123. The extrusion plate 225 is limited within the limiting area 123, so that the retaining flange 122 and the contact switch 2421 of the reset control board 242 together limit the extrusion plate 225 within the limiting area 123, so that the extrusion plate 225 can be reliably limited within the mounting hole 120, preventing the extrusion plate 225 from detaching from the mounting hole 120, thereby greatly improving the stability of the coffee brewing equipment 10.

[0052] like Figures 1 to 6 As shown, in one embodiment, a pressing flange 2252 protrudes from one side of the extrusion plate 225 adjacent to the contact switch 2421 of the reset control plate 242. The pressing flange 2252 is disposed opposite to the contact switch 2421 of the reset control plate 242. The pressing flange 2252 is used to contact and press the contact switch 2421 of the reset control plate 242, so that the extrusion plate 225 can concentrate the thrust transmitted by the transmission seat 222 onto the triggering area of ​​the contact switch 2421 through the pressing flange 2252, so as to achieve local force and precise triggering, and avoid the situation where the thrust is dispersed due to the excessive contact area between the extrusion plate 225 and the contact switch 2421. This greatly improves the triggering sensitivity of the contact switch 2421. At the same time, through point-to-surface precise pressure, the contact switch 2421 is ensured to be uniformly stressed and reliably operated, effectively preventing the contact switch 2421 from jamming due to force deviation, and further improving the stability of the coffee brewing equipment 10.

[0053] like Figures 1 to 7 As shown, in one embodiment, the water outlet 110 forms a water outlet channel 113, and the brewing body 100 also includes a water outlet pipe 130. The water outlet pipe 130 passes through the water outlet channel 113 and the clearance hole 211 in sequence and is disposed in the mounting cavity 212. The two ends of the water outlet pipe 130 are respectively connected to the elastic water supply pipe 250 and the water outlet 320, and the two ends of the water outlet pipe 130 are respectively sealed to the elastic water supply pipe 250 and the water-air separation box 300.

[0054] like Figure 2 and Figure 7 As shown, in one embodiment, the sealing connection between the water outlet pipe 130, the flexible water supply pipe 250, and the water-air separation box 300 is achieved by sealing with sealant or by interference fit.

[0055] like Figures 1 to 5As shown, in one embodiment, a pushing flange 2233 protrudes from one side of the pusher 223 adjacent to the deflection nozzle holder 230. The pushing flange 2233 is positioned opposite to the deflection area 2312 of the deflection part 231, so that the pusher 223 can concentrate the thrust of the pusher 223 onto the designated deflection area 2312 of the deflection part 231 through the pushing flange 2233, thereby achieving point-to-point force application and precise drive. This avoids the deflection action of the deflection part 231 being delayed due to excessive force area or force position deviation, and reduces the deflection response time of the deflection part 231. At the same time, by applying concentrated pressure locally, the deflection angle of the deflection nozzle holder 230 is made more stable and controllable, effectively preventing the deflection part 231 from deflection jamming, shaking, or angle deviation caused by uneven force. This ensures the accurate movement trajectory of the nozzle 232 and the stable and reliable water injection path, thereby improving the operational stability of the coffee brewing equipment 10.

[0056] like Figures 2 to 5 As shown, in one embodiment, the deflection portion 231 has two circumferentially opposite ends provided with rotating units 233. Both rotating units 233 are rotatably connected to the inner circumferential wall of the mounting cavity 212. The deflection portion 231 is divided into two deflection regions 2312 with the line connecting the axes of the two rotating units 233 as a reference. The pushing end of the pushing component 220 is positioned opposite to one of the deflection regions 2312, so that when the pushing end of the pushing component 220 presses against the deflection region 2312 of the deflection portion 231, the deflection is achieved. The deflector 231 will rotate around the axis connecting the two rotating units 233 as the center of rotation, so as to achieve stable deflection of the deflector 231 and drive the water outlet 232 to swing synchronously, ensuring that the water trajectory is accurate and controllable. When the pressing force of the pushing end of the pushing component 220 on the deflector 231 gradually decreases, the deflector water outlet bracket 230 can automatically return to its original position by relying on the elastic restoring force of the elastic water supply pipe 250, so as to realize the swing angle adjustment of the water outlet 232, thereby greatly improving the stability and convenience of use.

[0057] like Figure 5 As shown, in this embodiment, the rotating unit 233 is a rotating shaft or bushing, so that the deflecting part 231 can rotate relative to the rotating tank 210 through the rotating unit 233.

[0058] like Figure 5 As shown, in one embodiment, the deflection angle of the deflection unit 231 is 0~30°.

[0059] like Figures 1 to 8As shown, in one embodiment, the coffee brewing device 10 further includes a water-air separation box 300. The water-air separation box 300 is installed and fixed on the brewing body 100 and positioned above the rotating tank 210. The water-air separation box 300 forms a water-air separation chamber 310. One end of the water-air separation box 300 has a water outlet 320 connected to the water-air separation chamber 310 at its bottom. The water outlet 320 is connected to the water outlet pipe 130. The other end of the water-air separation box 300 has a water inlet 330 connected to the water-air separation chamber 310 on its outer wall. Water and air... The top end face of the separator 300 is formed with an exhaust port 340 that communicates with the water-air separation chamber 310. The top of the water-air separation chamber 300 is also provided with an exhaust pipe 350 that communicates with the exhaust port 340. This allows the water-air separation chamber 310 to provide sufficient space for the gas entrained in the water flow to be effectively released and discharged outward through the exhaust port 340 when water flows into the water-air separation chamber 310 through the inlet 330. This achieves the separation of water flow and gas, ensures the stability of water flow, and effectively improves the uniformity and extraction effect of coffee extraction.

[0060] like Figures 1 to 5 As shown, in one embodiment, a clearance area 215 is formed between the water outlet 232 and the wall of the water outlet 213, so that the clearance area 215 can provide sufficient clearance space for the swing of the water outlet 232, avoid the problem of motion interference between the water outlet 232 and the wall of the water outlet 213 during the swing, and ensure the swing stability of the deflector bracket 230.

[0061] like Figure 10 As shown, this disclosure also provides a brewing method, in which coffee is brewed using the coffee brewing device 10 of any of the above embodiments. The brewing method includes some or all of the following steps: S10, Instruction to obtain water discharge trajectory, wherein the water discharge trajectory includes at least one of the following: a central single-point shape, a spiral shape, and a circular shape; In this embodiment, the instruction to obtain the water outlet trajectory is used so that the coffee brewing device 10 can perform corresponding water outlet operations according to different water outlet trajectories.

[0062] S20, according to the instruction of the water outlet trajectory, the drive control component 240 is controlled to operate, so that the drive end of the drive control component 240 drives the rotating tank 210 to rotate relative to the brewing body 100.

[0063] In this embodiment, the drive control component 240 is controlled to operate according to the instruction of the water outlet trajectory, causing the drive end of the drive control component 240 to drive the rotating tank 210 to rotate relative to the brewing body 100. The rotating tank 210 can drive the push component 220 to rotate relative to the water outlet 110. The drive control component 240 can control the deflection angle of the deflection nozzle holder 230 by controlling the rotation direction and rotation position of the push component 220, so that the water outlet 232 can output the corresponding water outlet trajectory. Specifically, when the first threaded part 111 and the second threaded part 2211 are... During the screw-driven operation, the drive control component 240 can control the push end of the push component 220 to slide towards or away from the deflector nozzle holder 230, thereby adjusting the deflection angle of the deflector nozzle holder 230 relative to the rotating tank 210. As the push end of the push component 220 moves towards the deflector nozzle holder 230, the push end of the push component 220 gradually increases the supporting force on the deflection area 2312 of the deflection part 231, causing the deflection angle of the deflector nozzle holder 230 relative to the rotating tank 210 to gradually increase; conversely, as the push end of the push component 220 moves away from the deflector nozzle holder 230, the deflection angle of the deflector nozzle holder 230 gradually increases. During the nozzle holder 230 process, the pushing end of the pushing component 220 gradually reduces the resistance force on the deflection area 2312 of the deflection part 231. The elastic water pipe 250 can then perform a reset operation through its own elasticity, causing the deflection angle of the deflection nozzle holder 230 relative to the rotating tank 210 to gradually decrease, resulting in a spiral water discharge trajectory from the outlet 232. When the drive control component 240 drives the pushing end of the pushing component 220 to slide towards the deflection nozzle holder 230 until the second threaded part 2211 moves to the first preset position of the water outlet 110, the second threaded part... When the threaded part 2211 disengages from the first threaded part 111 and is located in the idle zone 112, the compression of the elastic support 260 is at its maximum. At this time, the elastic support 260 supports the top end face of the second threaded part 2211 to slide against the bottom end face of the first threaded part 111 through its own elastic properties, so that the second threaded part 2211 is limited to the idle zone 112 and idles in the idle zone 112. This causes the pushing end of the pushing component 220 to press the deflecting nozzle frame 230 with the maximum holding force. The deflecting nozzle frame 230 maintains the maximum deflection angle, so that the water outlet 232 outputs a water trajectory in a circular shape.When the drive control component 240 drives the push end of the push component 220 to slide away from the deflection nozzle holder 230 until the second threaded portion 2211 moves to the second preset position of the water outlet 110, the resistance between the push end of the push component 220 and the deflection portion 231 is zero, so that the deflection nozzle holder 230 can be reset to its initial state through the elastic performance of the elastic water supply pipe 250, so that the center line of the connecting hole 2311 and the center axis of the rotating tank 210 are on the same straight line, and the drive end of the drive control component 240 stops driving the rotating tank 210, so that the deflection angle of the deflection nozzle holder 230 is zero, so that the water outlet 232 outputs a water trajectory in the shape of a single point in the center; at the same time, when the second threaded portion 2211 is idling in the idling area 112, the drive control component 240 drives the second threaded portion 2211 to slide away from the deflection nozzle holder 230. The second threaded portion 2211 rotates in the first rotation direction, allowing it to be threadedly connected to the first threaded portion 111 by the support and pushing action of the elastic support member 260, and slide away from the deflection nozzle holder 230, thereby changing the water outlet trajectory of the nozzle 232 from a circular shape to a spiral shape. When the second threaded portion 2211 is located at the second preset position of the water outlet 110, the control drive component 240 drives the second threaded portion 2211 to rotate in the second rotation direction, allowing the pushing end of the pushing component 220 to overcome the elastic support force of the elastic support member 260 and move closer to the deflection nozzle holder 230 through the screw connection between the first threaded portion 111 and the second threaded portion 2211, thereby changing the water outlet trajectory of the nozzle 232 from a single-point shape to a spiral shape.

S123, determine whether the drive end of the drive control component 240 is in the initial position; if so, control the drive end of the drive control component 240 to stop resetting, at which point the drive end of the drive control component 240 has completed the reset.

[0073] In this embodiment, it is determined whether the drive end of the drive control component 240 is in the initial position; if so, the drive end of the drive control component 240 is controlled to stop resetting. At this time, the drive end of the drive control component 240 has completed the reset. Whenever the coffee brewing device 10 completes the corresponding water dispensing operation, the drive control component 240 will drive the push component 220 to perform a reset operation so that the second threaded part 2211 can move relative to the water dispensing part 110 to the second preset position.
