Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and more particularly to a display screen adjustment structure for a coffee machine. Background Technology

[0002] As people pursue a higher quality of life, their demand for diversified beverages has greatly increased. Simultaneously, with the development of information technology, more people are beginning to value healthy food. Currently, mainstream coffee machines on the market mainly consist of two core components: extraction and grinding, which can basically meet the needs of coffee beverages. In addition, some coffee machines can make cross-category beverages, allowing users to satisfy their different beverage needs with a single machine.

[0003] In existing coffee machines that offer multiple beverage options, the operation of switching between different speed settings to adjust the beverage output is quite complicated, and the internal structure and components are complex. User errors may cause users to fail to switch speeds, resulting in a waste of resources and materials. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a display screen adjustment structure for a coffee machine, based on the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a display screen adjustment structure for a coffee machine, including a main unit and a gear switching adjustment structure disposed on the main unit. The main unit is provided with a main control structure. The gear switching adjustment structure and the main control structure are electrically connected. The gear switching adjustment structure controls the main control structure to switch the output of different beverages. The gear switching adjustment structure includes a gear rotation structure, a control structure, and a display structure. Rotating the gear rotation structure causes the control structure connected to the gear rotation structure to send an electrical transmission signal to the main control structure. The control structure controls the main control structure to switch the type of beverage output. The control structure simultaneously sends an electrical transmission signal to the display structure. The display structure is electrically connected and outputs graphic and text signals to the outside world.

[0006] Preferably, the control structure includes a PCB base cover and a main PCB board disposed inside the PCB base cover. An encoder for generating signals is soldered onto the main PCB board. The encoder is disposed on the main PCB board through a downwardly extending connecting post. An mounting post that mates with the connecting post extends upward from the inner wall of the PCB base cover. The encoder includes an integrally formed upper part and a lower part. The lower part is soldered and fixedly disposed on the main PCB board, and the upper part is rotatably connected to the gear shifting structure.

[0007] Preferably, the gear shifting structure includes an adjustment disc and a fixing ring snapped onto the outside of the adjustment disc. The adjustment disc has a hollow structure in the middle, a gear ring that works with the display structure to produce a gear shifting sound around the outer ring of the hollow structure, a number of hooks evenly spaced around the inner ring of the hollow structure, and slots that work with the hooks evenly spaced around the upper outer edge.

[0008] Preferably, rotating the fixed ring causes the adjusting disk to rotate synchronously, which in turn causes the upper part connected to it to rotate. The upper part rotates and communicates with the lower part to generate a signal, which is then transmitted to the main PCB board connected to it through the lower part.

[0009] Preferably, the display structure includes a base plate and a display PCB board snapped into the base plate. The inner wall of the base plate is fixedly connected to the main PCB board near the bottom by screws. The base plate is provided with at least one gear shift paddle that cooperates with the gear ring to produce a gear shifting sound. The gear shift paddle is elastic. During the rotation of the adjustment disc, the base plate remains stationary, and the gear shift paddle moves elastically along the gear ring and produces a sound.

[0010] Preferably, the display structure further includes a light shield mounted on the base plate, the outer edge of the light shield being fixedly connected to the base plate by screws, and a panel for displaying graphic signals being fixedly mounted on the top surface of the light shield.

[0011] Preferably, it also includes a light guide post, which is arranged inside the PCB bottom cover. The light guide post includes a light guide ring arranged on the outside. The light guide ring is arranged between the outer wall of the PCB bottom cover and the outer wall of the fixing ring. The bottom surface of the inner wall of the light guide post and the top surface of the main PCB board are in contact and connected. The light guide post and the main PCB board are electrically connected.

[0012] Compared with the prior art, the advantages of this utility model are as follows: by rotating the gear shift mechanism, the control structure is electrically connected and transmits signals to the main control structure in the host, so that the main control structure controls the switching of the types of beverages output. At the same time, the control structure transmits signals to the display structure, and the display structure is electrically connected and outputs graphic signals to the outside world. The structure is simple, easy to operate, reduces the operation error rate, and improves the sensitivity of beverage switching. Attached Figure Description

[0021] like Figures 1 to 2 As shown, this utility model provides a display screen adjustment structure for a coffee machine, including a main unit and a gear switching adjustment structure disposed on the main unit. The main unit has a main control structure, and the gear switching adjustment structure and the main control structure are electrically connected. The gear switching adjustment structure controls the main control structure to switch the output of different beverages. Specifically, the gear switching adjustment structure includes a gear rotation structure, a control structure, and a display structure. Rotating the gear rotation structure causes the control structure connected to the gear rotation structure to send an electrical transmission signal to the main control structure. The control structure controls the main control structure to switch the type of beverage output. At the same time, the control structure sends an electrical transmission signal to the display structure, and the display structure is electrically connected and outputs graphic signals to the outside world.

[0022] The control structure includes a PCB base cover 1 and a main PCB board 2 disposed inside the PCB base cover 1. An encoder 3 for generating signals is soldered onto the main PCB board 2. The encoder 3 is disposed on the main PCB board 2 through a downwardly extending connecting post. Specifically, the inner wall of the PCB base cover 1 is provided with an upwardly extending mounting post that is inserted into the connecting post. The encoder 3 includes an integrally formed upper part 4 and a lower part 5. The lower part 5 is soldered and fixedly disposed on the main PCB board 2, and the upper part 4 is rotatably connected to the gear shifting structure.

[0023] The gear shifting structure includes an adjustment disc 6 and a fixing ring 7 snapped onto the outside of the adjustment disc 6. The adjustment disc 6 has a hollow structure 8 in the middle and a gear ring 9 around the outer ring of the hollow structure 8, which works with the display structure to produce a gear shifting sound. Specifically, a number of hooks 10 are evenly spaced around the inner ring of the hollow structure 8, and slots 11 that work with the hooks 10 are evenly spaced around the outer edge of the upper part 4.

[0024] Rotating the fixed ring 7 causes the adjusting disk 6 to rotate synchronously. The adjusting disk 6 causes the upper part 4 connected to it to rotate. The upper part 4 rotates and communicates with the lower part 5 to generate a signal. The signal is transmitted to the main PCB board 2 connected to it through the lower part 5.

[0025] The display structure includes a base plate 12 and a display PCB board 13 snapped into the base plate 12. The inner wall of the base plate 12 is fixedly connected to the main PCB board 2 near the bottom by screws. The base plate 12 is provided with at least one gear shift paddle 14 that cooperates with the gear ring 9 to make a gear shifting sound. Specifically, the gear shift paddle 14 is elastic. During the rotation of the adjustment disk 6, the base plate 12 remains stationary, and the gear shift paddle 14 moves elastically along the gear ring 9 and makes a sound.

[0026] The display structure also includes a light shield 15 mounted on the base plate 12, with the outer edge of the light shield 15 fixedly connected to the base plate 12 by screws; specifically, a panel 16 for displaying graphic signals is fixedly mounted on the top surface of the light shield 15.

[0027] It also includes a light guide post 17, which is arranged inside the PCB bottom cover 1. The light guide post 17 includes a light guide ring 18 arranged on the outside. Specifically, the light guide ring 18 is arranged between the outer wall of the PCB bottom cover 1 and the outer wall of the fixing ring 7. The bottom surface of the inner wall of the light guide post 17 is in contact with the top surface of the main PCB board 2, and the light guide post 17 is electrically connected to the main PCB board 2.

[0028] The working principle of this utility model is as follows: The user rotates the fixed ring 7, which drives the adjustment disk 6 to rotate. The adjustment disk 6 drives the gear ring 9 to rotate synchronously. Since the adjustment disk 6 is connected to the slot 11 of the upper part 4 of the encoder 3 through the hook 10, the adjustment disk 6 drives the upper part 4 to rotate synchronously, but the lower part 5 of the encoder 3 remains stationary. During the rotation of the upper part 4, it is electrically connected to the lower part 5. At the same time, the upper part 4 generates a signal and transmits it to the lower part 5. Then, the lower part 5 transmits the signal to the main PCB board 2 that is soldered to it. The main PCB board 2 is electrically connected to the main control structure in the host and transmits the signal to the main control structure. The main control structure controls the host to switch and adjust the output of different beverages.

[0029] Meanwhile, the main PCB board 2 transmits signals to the display PCB board 13. The display PCB board 13 is electrically connected and outputs graphic signals to the outside world through the panel 16. A spring is provided between the display PCB board 13 and the panel 16. After the user selects a pattern by touching the panel 16, the extraction process is started. Since the display PCB board 13 is also electrically connected to the main control structure, the graphic information displayed on the panel 16 corresponds to the output of different beverages in the main unit.

[0030] Since the adjustment disc 6 drives the gear ring 9 to rotate synchronously, while the base plate 12 remains stationary, the gear shift lever 14 on the base plate 12 is elastically moved along the rotating gear ring 9 and makes a sound, which improves the user's experience in switching the type of beverage to adjust by rotating the fixed ring 7 and improves the precision of control.

[0031] The control structure and electrical connection relationship in this utility model are common and easily conceived technical means for those skilled in the art, so they will not be described in detail.

[0032] The advantages of this invention are as follows: by rotating the gear shift mechanism, the control structure is electrically connected and transmits signals to the main control structure inside the host, enabling the main control structure to control the switching of beverage types. At the same time, the control structure transmits signals to the display structure, which is electrically connected and outputs graphic signals to the outside world. The structure is simple, easy to operate, reduces the error rate, and improves the sensitivity of beverage switching.
