Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a spiral brewing mechanism for a coffee machine. Background Technology

[0002] A coffee machine is a general term for a coffee brewing machine. As people's living standards continue to improve, they have an increasing pursuit of homemade coffee and coffee flavor.

[0003] In existing coffee machines, the liquid flows directly onto the coffee grounds during brewing. Because the water droplets on the coffee cup typically leave circular or dotted marks, the contact area between the water and the coffee grounds is small, resulting in incomplete saturation of the grounds. This leads to uneven extraction, low efficiency, and difficulty in brewing high-quality coffee. Therefore, traditional coffee machines are increasingly unable to meet the growing demand from consumers for higher-quality coffee.

[0004] In view of this, application publication number CN117860112A discloses a spiral drive mechanism and a spiral-watering fully automatic coffee machine. Specifically, the spiral drive mechanism includes a water outlet pipe, a first rotating mechanism, and a first lifting mechanism. The first rotating mechanism includes a mounting bracket, a rotating base, a rotating platform, a rotating wheel, and a rotating drive assembly. The rotating base is rotatably mounted on the mounting bracket, and the water outlet pipe is oscillatingly mounted on the rotating base. The rotating base, the rotating platform, and the rotating wheel are arranged in parallel, and the rotating base and the rotating wheel are connected by a rotating drive rod. The rotating platform is slidably mounted on the rotating drive rod, and the rotating drive assembly is drively connected to the rotating base or the rotating wheel. A connecting rod is provided between the water outlet pipe and the rotating platform. The first lifting mechanism is connected to the rotating platform to drive the rotating platform to move up and down, thereby causing the water outlet pipe to oscillate. The rotating drive assembly includes a first rotating motor and a drive gear. The drive gear is connected to the first rotating motor, and transmission teeth are provided on the rotating wheel or the rotating base, meshing with the drive gear. The first lifting mechanism includes a lifting motor, a lifting gear, a rack, and a bracket. The bracket is provided with a rotating groove adapted to the rotary table. The bracket is connected to the rotary table. The lifting motor drives the bracket to move up and down through the lifting gear and the rack. The first lifting mechanism also includes a lead screw module and a lifting adapter block. The rotary table is rotatably disposed within the lifting adapter block. The lead screw module is connected to the lifting adapter block. The lead screw module includes a lead screw positioning frame and a second lead screw motor. A second lead screw and a second guide rail are provided on the lead screw positioning frame. A second slide is slidably disposed on the second guide rail, and the second slide is threadedly connected to the second lead screw. The second lead screw motor is drively connected to the second lead screw.

[0005] However, while the aforementioned spiral drive mechanism has certain advantages, it is necessary to provide a spiral flushing mechanism with an alternative structure to meet the diverse needs of different customers in order to satisfy the different demands of the market. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a spiral brewing mechanism for a coffee machine, which can make the water outlet of the water pipe form a bolt-shaped moving trajectory, thereby increasing the contact area between water and coffee powder, so that the powder layer can be fully wetted, improving the extraction efficiency of coffee powder, and thus brewing high-quality coffee.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] Furthermore, the swing assembly also includes a reset sensor and a reset block; the reset sensor is installed at the lower end of the bracket and electrically connected to the second set of conductive lines; the reset block is connected to the swing block and cooperates with the reset sensor; when the reset block is sensed by the reset sensor, the swing block is in its initial position.

This configuration facilitates the installation of all components.

[0011] Furthermore, the swing block includes a main body with the mounting hole in the middle and a first connecting part and a second connecting part respectively connected to both sides of the main body; the upper end of the first connecting part is connected to the output shaft of the swing motor; the upper end of the second connecting part is hinged to the lower connecting frame via a hinge shaft; the reset block is mounted on the hinge shaft. This configuration facilitates the installation of the swing block while simultaneously allowing the reset block to rotate during swinging, thus enabling the reset block to cooperate with the reset sensor.

[0012] Furthermore, a strip-shaped hole is provided on the bottom surface of the lower connecting frame, corresponding to the swing direction of the swing block and used to limit the swing range of the main body; the lower end of the main body passes through the strip-shaped hole.

Therefore, as the swing block drives the water outlet pipe to swing upward, the rotation of the swing block allows the water outlet to form a bolt-shaped movement trajectory, thereby increasing the contact area between water and coffee grounds, ensuring complete saturation of the coffee grounds, improving extraction efficiency, and resulting in high-quality coffee.

[0020] In addition, after brewing coffee, when the swing block resets, the water outlet of the water pipe can be accurately returned to its original position through the sensing cooperation between the reset block and the reset sensor, so that the next round of work can be carried out.

[0036] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0037] like Figures 1-5 As shown, a spiral brewing mechanism for a coffee machine includes a fixed base 1 and a water outlet pipe 2, a rotating component 3, and a swinging component 4, which are respectively located on the fixed base 1.

[0038] The rotating component 3 includes a rotating motor 31, a conductive slip ring 32, and a bracket 33.

[0039] like Figure 1 and Figure 5 As shown, a rotary motor 31 is mounted on a fixed base 1, and the output shaft of the rotary motor 31 is connected to the outer ring 321 of the conductive slip ring 32, so that the rotary motor 31 can drive the outer ring 321 of the conductive slip ring 32 to rotate. The inner ring 322 of the conductive slip ring 32 is positioned. A first set of conductive wires 5 is provided on the inner ring 322 of the conductive slip ring 32, and a second set of conductive wires 6 electrically connected to the first set of conductive wires 5 is provided on the outer ring 321 of the conductive slip ring 32. The upper end of the bracket 33 is mounted on the outer ring 321 of the conductive slip ring 32, so that the outer ring 321 can drive the bracket 33 to rotate synchronously when it rotates. Of course, a conductive component (not shown in the figure) is also provided between the inner ring 322 and the outer ring 321 of the conductive slip ring 32 to facilitate energization, but since the conductive slip ring 32 is existing technology, its structure and principle will not be described in detail here. Both the first group of conductive lines 5 and the second group of conductive lines 6 include signal lines and power lines, but since these are existing technologies, they will not be described in detail here.

[0040] In addition, the swing assembly 4 includes a swing motor 41 and a swing block 42.

[0041] like Figure 3 and Figure 5 As shown, the swing motor 41 is installed at the lower end of the bracket 33 and electrically connected to the second set of conductive wires 6, so that when the outer ring 321 of the conductive slip ring 32 rotates, the first set of conductive wires 5 and the second set of conductive wires 6 will not be entangled. Moreover, the conductive wires can provide power to the swing motor 41. The swing block 42 is mounted on the output shaft of the swing motor 41 in a swinging manner so that the swing motor 41 can drive the swing block 42 to swing up and down.

[0042] like Figure 1 and Figure 4 As shown, the lower end of the water outlet pipe 2 (i.e. the water outlet end with the water outlet) passes through the inner ring 322 of the conductive slip ring 32 and the bracket 33, and then passes through a mounting hole 421 of the swing block 42. The lower end of the water outlet pipe 2 is connected to the outside of the bracket 33, so that water can be easily discharged.

[0043] During use, the rotating component 3 can drive the swing component 4 to rotate via the bracket 33, thereby rotating the swing block 42. The swing motor 41 can be used to drive the swing block 42 to swing up and down, so as to synchronously drive the water outlet of the water pipe 2 to swing up and down. Therefore, after the swing motor 41 drives the swing block 42 and drives the lower end (i.e., the water outlet) of the water pipe 2 to swing upward gradually, the rotating motor 31 is then used to drive the swing block 42 to rotate, so that the water outlet of the water pipe 42 can form a spiral movement trajectory.

[0044] like Figure 3 and Figure 5 As shown, the swing assembly 4 also includes a reset sensor 43 and a reset block 44; the reset sensor 43 is installed at the lower end of the bracket 33 and electrically connected to the second set of conductive wires 6; the reset block 44 is connected to the swing block 42 and cooperates with the reset sensor 43; when the reset block 44 is sensed by the reset sensor 43, the swing block 42 is in the initial position to ensure that the lower end of the water outlet pipe 42 is in the original position.

[0045] In summary, the rotary motor 31 of this invention can drive the swing block 42, on which the water outlet pipe 2 is mounted, to rotate via the bracket 33, and the swing motor 41 can synchronously drive the swing block 42 to swing up and down. Therefore, when the swing block 42 drives the water outlet pipe 2 to swing upwards, and then drives the swing block 42 to rotate, the water outlet of the water outlet pipe 2 can form a bolt-shaped movement trajectory, thereby increasing the contact area between water and coffee powder, allowing the powder layer to be fully saturated, improving the extraction efficiency of the coffee powder, and thus brewing high-quality coffee. In addition, after brewing the coffee, when the swing block 42 resets, the water outlet of the water outlet pipe 42 can be accurately returned to its original position through the sensing cooperation between the reset block 44 and the reset sensor 43, so as to start the next round of work.

[0046] In this embodiment, the bracket 33 includes an upper connecting frame 331 and a lower connecting frame 332 that are vertically distributed and detachably connected to each other; both the upper connecting frame 331 and the lower connecting frame 332 are hollow structures; the upper connecting frame 331 is sleeved and fixed on the outer ring 321 of the conductive slip ring 32; the swing motor 41 and the reset sensor 43 are respectively installed on both sides of the lower connecting frame 332; the swing block 42 is located at the center of the lower connecting frame 332, the first side of the swing block 42 is connected to the output shaft of the swing motor 41, and the second side is hinged to the side wall of the lower connecting frame 332; the reset block 44 is connected to the second side of the swing block 42. Therefore, the above arrangement allows the swing assembly 4 to be easily installed on the bracket 33, and the swing motor 41 can easily drive the swing block 42 to swing. At the same time, the reset block 44 can easily cooperate with the reset sensor 43.

[0047] like Figure 3 As shown, in this embodiment, the swing block 42 includes a main body 422 with a mounting hole 421 in the middle, and a first connecting part 423 and a second connecting part 424 respectively connected to both sides of the main body 422; the upper end of the first connecting part 423 is connected to the output shaft of the swing motor 41; the upper end of the second connecting part 424 is hinged to the lower connecting frame 332 through a hinge shaft (not shown in the figure); the reset block 44 is installed on the outer end of the hinge shaft. Therefore, the above arrangement facilitates the installation of the swing block 42, and also allows the swing block 42 to drive the reset block 44 to rotate simultaneously when swinging, so that the reset block 44 can cooperate with the reset sensor 43.

[0048] As a specific configuration, the reset sensor 43 is a contact sensor; a sensing part 441 is provided on the reset block 44 for contacting the reset sensor 43. Therefore, when the reset block 44 rotates, when the sensing part 441 contacts the reset sensor 43, the swing block 42 rotates to its original position, which means that the water outlet of the water pipe 2 also moves to its original position.

[0049] like Figure 4 As shown, preferably, a strip hole 333 is provided on the bottom surface of the lower connecting frame 332, which corresponds to the swing direction of the swing block 42 and is used to limit the swing range of the main body 422; the lower end of the main body 422 passes through the strip hole 333, so that the main body 422 can move within the range of the strip hole 333.

[0050] like Figure 3 As shown, a locking hole 334 is provided on each side of the lower end of the upper connecting frame 331; a buckle 335 that mates with the locking hole 334 is provided on each side of the upper end of the lower connecting frame 332; the two buckles 335 can be correspondingly engaged in the two locking holes 334. This arrangement allows for easy assembly and disassembly of the upper connecting frame 331 and the lower connecting frame 332 for use. In use, simply engage the buckles 335 in the locking holes 334 to install both.

[0051] In this embodiment, a bearing 34 is provided on the fixed base 1; the outer ring of the bearing 34 is connected to the fixed base 1; the lower end of the lower connecting bracket 332 passes through the middle of the bearing 34 and is connected to the inner ring of the bearing 34. Therefore, by providing the bearing 34, the stability of the bracket 33 during rotation can be ensured.

[0052] like Figure 1 and Figure 3 As shown, the rotary motor 31 is connected to the outer ring 321 of the conductive slip ring 32 via a gear assembly. Specifically, the gear assembly includes a large gear 7 fitted on the outer ring 321 of the conductive slip ring 32 and a small gear 8 mounted on the output shaft of the rotary motor 31 and meshing with the large gear 7. Therefore, through the cooperation of the large gear 7 and the small gear 8, the rotary motor 31 can be easily driven to the outer ring 321 of the conductive slip ring 32.

[0053] like Figure 1 As shown, in this embodiment, the bottom surface of the large gear 7 is fixedly connected to the upper end of the bracket 33, so that the large gear 7 can drive the bracket 33 when it rotates.

[0054] like Figure 1 As shown in the figure, in this embodiment, a sleeve (not shown in the figure) can also be fixedly installed in the middle of the inner ring 322 of the conductive slip ring 32, and then the water outlet pipe 2 is inserted into the sleeve, so as to avoid friction between the inner ring 322 and the water outlet pipe 2.

[0055] like Figure 2 As shown, the upper end of the outlet pipe 2 is the inlet 21, which is used to connect other water supply equipment (not shown in the figure).

[0056] The following describes the specific working principle of this utility model in order to help you understand it:

[0057] First, after the fixed base 1 is secured, water flows downward from the outlet pipe 2. Next, the rotary motor 31 drives the swing block 42 to rotate via the bracket 33. Simultaneously, the swing motor 41 drives the swing block 42 to gradually swing upward, creating a spiral trajectory at the outlet of the water pipe 42, improving the extraction efficiency of the coffee powder. At the same time, the reset block 44 also rotates upward until the swing block 42 reaches a preset position, at which point both the swing motor 41 and the rotary motor 31 stop. After brewing, the swing motor 41 drives the swing block 42 to reset, causing the reset block 44 to reset accordingly. When the sensing part 441 of the reset block 44 is detected by the reset sensor 43, the swing motor 41 stops, and the outlet of the water pipe 2 returns to its original position, ready for the next cycle.

[0058] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
