Technical Field

[0001] The utility model relates to the technical field of coffee machines, and particularly relates to a coffee machine brewing mechanism. Background Art

[0002] With the increasing popularity of coffee-drinking habits, as a modern coffee-making device, the fully automatic coffee machine has the remarkable advantages of convenience and consistency. It can quickly make coffee with stable quality, and is suitable for home, office and commercial environments. Users can enjoy delicious coffee without the need for professional coffee-making skills.

[0003] The main working process of the fully automatic coffee machine includes: raw material preparation, where the user adds water to the water tank and coffee beans to the grinding device; grinding, after the user selects the coffee type, the grinding device automatically grinds an appropriate amount of coffee beans; tamping, the ground coffee powder falls into the brewing device; brewing, the brewing device swings to align with the brewing head, the brewing head of the brewing device extends into the brewing device to compact the coffee powder, and high-pressure hot water is introduced. Through the coffee powder, coffee is extracted. The water pressure is usually between 9 and 19 bar to ensure the full extraction of the coffee flavor; the coffee flows out, the brewed coffee flows through the liquid outlet pipeline and into the cup through the outlet, completing the production of coffee. Some fully automatic coffee machines also have functions such as making milk foam with steam, automatically cleaning the brewing head and internal pipelines, and automatically shutting down.

[0004] In the current technology, the coffee machine brewing mechanism needs to move under the drive of the driving device, align with the grinding device of the coffee machine at the initial position to load coffee powder; align with the brewing device at the brewing position, so that the brewing head of the brewing device enters the brewing mechanism to mix hot water and coffee powder to make coffee liquid; at the residue discharging position, the coffee residue remaining in the brewing device after brewing is pushed out to load coffee powder again for the next coffee brewing. Generally speaking, the swing design of the coffee machine brewing mechanism is to achieve precise control of the brewing head, including extending into the brewing cup for coffee brewing and swinging after exiting the brewing chamber to facilitate powder loading and coffee residue cleaning, improving the user experience and the efficiency of the coffee machine.

[0005] To ensure the brewing effect, it is necessary to determine that after the brewing mechanism reaches positions such as the initial position and the brewing position, the control device starts the next process. Currently, microswitches are mostly used to detect and determine positions. When multiple positions need to be detected and determined, too many microswitches will occupy the internal space of the coffee machine, and the coffee powder floating in the machine body during long-term use will affect the action sensitivity of the microswitches, resulting in the failure of the microswitches and affecting the use of the coffee machine.

[0034] Next, refer to Figures 1 - 5 Describe a coffee machine brewing mechanism according to some embodiments of the present application.

[0035] The present utility model provides a coffee machine brewing mechanism through the following technical solutions, including: a brewing device 1, the initial position of the brewing device 1 is directly below a grinding device (not shown in the figure) to receive coffee powder; then it swings to the brewing position driven by a driving device 3, that is, below a brewing device 2, and the opening of a brewing cup 12 is aligned with a brewing head of a brewing device 4, so that the brewing head accurately enters the brewing cup 12 to inject hot water into the coffee powder to complete the brewing of coffee; after the brewing is completed, the driving device 3 rotates in reverse to drive a slag discharging component (not shown in the figure) in the brewing device 1 to rise to push out the coffee slag in the brewing device 1. At this time, although the brewing device 1 still stays at the brewing position, the slag discharging component inside it has completed the corresponding movement driven by the driving device 3. Therefore, the movement position of the driving device 3 at this time is the slag discharging position; after the slag discharging is completed, the brewing device 1 swings back to the initial position driven by the driving device 3 to prepare for the next coffee making.

[0036] In the technical solution of this embodiment, the driving device 3 is drivingly connected to the brewing device 1. The driving device 3 has a first position for moving the brewing device 1 to the initial position, a second position for moving the brewing device 1 to the brewing position, and a slag discharging position. The initial position and the brewing position are the movement positions of the brewing device 1, while the first position, the second position, and the slag discharging position are the movement positions for the driving device 3 to drive the brewing device 1 to perform processes such as powder receiving, brewing, and slag discharging, and they are in one-to-one correspondence with each other. Detecting the relevant positions of the driving device 3 can determine the relevant positions of the brewing device 1, which is convenient for the control device to start relevant operations according to the working process of the coffee machine.

[0037] A detection mechanism is provided to detect the movement positions of the brewing device 1 and the driving device 3. The detection mechanism and the driving device 3 are both connected to a control device of the coffee machine (not shown in the figure), and the control device controls the operation of the driving device 3 according to the signals detected by the detection mechanism. The driving device 3 includes a gearbox 35, and an output shaft 34, an output shaft gear 32, and other gears are provided inside the gearbox 35.

[0038] In the technical solution of this embodiment, the detection mechanism includes a first detection device. The first detection device is a Hall detection component 41. A magnetic component 31 is provided on a moving part of the driving device 3, and the Hall detection component 41 is arranged opposite to the magnetic component 31 to enable the Hall detection component 41 to detect whether the driving device 3 is in the first position, the second position, or the slag discharging position.

[0039] Specifically, the magnetic component 31 is disposed on the output shaft gear 32 of the driving device 3. The magnetic component includes a first magnetic member 311, a second magnetic member 312, a third magnetic member 313, and a fourth magnetic member 314 that are spaced apart. The Hall detection component 41 is disposed on the gearbox cover 33 corresponding to the magnetic component 31. The Hall detection component 41 includes a first Hall detection member 411, a second Hall detection member 412, and a third Hall detection member 413 that are spaced apart.

[0040] When the driving device 3 moves to the first position, the first Hall detection member 411 senses the first magnetic member 311 and the third Hall detection member 413 senses the third magnetic member 313;

[0041] When the driving device 3 moves to the second position, the second Hall detection member 412 senses the second magnetic member 312;

[0042] When the driving device 3 moves to the slag removal position, the third Hall detection member 413 senses the fourth magnetic member 314.

[0043] In the technical solution of this embodiment, the brewing device 1 has a detachable brewing cup (not shown in the figure), which is convenient for cleaning after use. Therefore, in order to detect and determine that the driving device 3 is connected to the complete brewing device 1, the detection mechanism further includes a second detection device. The second detection device includes a first microswitch assembly 42. The first microswitch assembly includes a first elastic pressing rod 421 and a first microswitch 422. The first elastic pressing rod 421 is disposed through the output shaft 34 of the driving device 3. The top end of the first elastic pressing rod 421 is exposed outside the head of the output shaft 34. The first microswitch 422 is disposed on the gearbox cover 33 corresponding to the bottom end of the first elastic pressing rod 421. When the brewing cup is removed from the brewing device 1, the brewing device 1 releases the pressing on the first elastic pressing rod 421. The bottom end of the first elastic pressing rod 421 retracts under the elastic force to disengage from the first microswitch 422, and the first microswitch 422 is turned off, and the control device pauses the operation of all coffee machines; when the brewing cup is correctly reinstalled into the brewing device 1, the brewing device 1 connected to the driving device 3 presses the first elastic pressing rod 421 and drives its bottom end to press the first microswitch 422, and the first microswitch 422 is turned on, and the control device resumes the normal operation of all coffee machines. The first microswitch assembly 42 determines the connection condition between the driving device 3 and the brewing device 1 by detecting the position of the brewing device 1.

[0044] The second detection device further includes a second microswitch assembly 43. The second microswitch assembly 43 includes a second elastic pressing rod 431 and a second microswitch 432. The second elastic pressing rod 431 is disposed on the outer surface of the brewing device 1, and the second microswitch 432 is disposed on the coffee machine body corresponding to the second elastic pressing rod 431 when the brewing device 1 is in the brewing position. When the brewing device 1 moves to the brewing position, it drives the second elastic pressing rod 431 to press the second microswitch 432, and the second microswitch 432 is turned on. When the brewing device is not in the brewing position, the second elastic pressing rod 431 disengages from the second microswitch 432, and the second microswitch 432 is turned off.

[0045] Since the brewing position is a crucial position for coffee brewing, it determines whether the brewing head of the brewing device 4 can correctly enter the brewing device 1 to complete the brewing. Therefore, in addition to the second Hall detection component 412 sensing the signal of the second magnetic component 312, the detection mechanism also adds the signal of the second microswitch assembly 43. Only after the control device obtains the two sets of signals can it start the next brewing operation, improving the reliability of the operation.

[0046] Connected to the brewing device 1 is the output shaft 34 of the driving device 3. The control device controls the rotation of the output shaft 34 according to the signals detected by the detection mechanism to achieve the movement of the brewing device 1 at different positions.

[0047] The detection mechanism uses a Hall detection component 41 to replace the microswitch to detect and determine the initial position, brewing position, and slag discharging position, reducing the number of microswitches and avoiding excessive occupation of the internal space of the coffee machine by the microswitches. At the same time, due to the working principle of the induction of the Hall detection component, it is basically not affected by the coffee powder in the machine body, ensuring the accuracy and effectiveness of the detection and determination of the relevant positions of the brewing device. For crucial positions such as the brewing position, a dual-signal determination method using the Hall detection component 41 and the second microswitch assembly 43 is adopted to further improve the reliability of the operation. For the detection and determination of the connection between the brewing device 1 and the driving device 3, a first microswitch assembly 42 is adopted, which is suitable for its elastic touch and pressing movement mode.

[0048] The detection mechanism only detects and determines the movement positions of the brewing device 1 and the driving device 3 by obtaining relevant signals, and does not have a physical limiting effect on the movement positions of the brewing device 1 and the driving device 3. The physical limitation of the movement positions of the brewing device 1 and the driving device 3 is still achieved through corresponding limiting structures, set motor operating parameters, etc.

[0049] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
