Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a transmission structure of a swinging part of a coffee machine. Background Art

[0002] With the increasing popularity of coffee drinking, fully automatic coffee machines, with their one-touch operation, time-saving features, guaranteed quality, and diverse options, have become a staple in many homes and offices. Within the transmission structure of the brewing mechanism of a fully automatic coffee machine, swinging is a crucial motion, involved in moving the brewing head and cleaning the coffee grounds. In current technology, the brewing mechanism's swinging assembly, driven by a drive motor, oscillates the brewing head. At its initial position, it aligns with the machine's grinder for loading coffee grounds. It then swings to a brewing position, aligning the brewing head with the brewing unit. The brewing head enters the brewing mechanism, mixing hot water and coffee grounds to create a delicious coffee. In some coffee machines with a detachable brewing cup, the brewing cup is also removed and installed by the brewing mechanism in the initial position. This swinging assembly typically includes a bracket for holding the brewing cup, a transmission gear, and a transmission mechanism. The bracket and transmission gear are rotatably connected to the coffee machine body about a rotational center, and the transmission gear is in transmission connection with the drive motor. This design not only simplifies the structure of the brewing mechanism but also facilitates miniaturization and a compact layout of the coffee machine.

[0003] In general, the oscillating design within the brewing mechanism of a coffee machine is designed to achieve precise control of the brewing head, including its insertion into the brewing cup for brewing and its subsequent swing out of the brewing chamber for easier filling and cleaning of grounds. This design, achieved through ingenious mechanical and position-limiting mechanisms, aims to enhance the user experience and improve the efficiency of the coffee machine.

[0004] To ensure brewing quality, a positioning mechanism is often used to control the brewing position, ensuring that the brew head enters the brewing cup in the correct position. However, without the necessary positioning mechanism, the initial position can easily deviate, resulting in spilled coffee grounds and difficulty in removing and installing the brewing cup, affecting the use of the coffee machine.

[0026] Refer to the following Figure 1-5 The present invention describes a transmission structure of an oscillating part of a coffee machine according to some embodiments of the present application.

[0027] The utility model provides a transmission structure of a coffee machine swing member through the following technical solutions, including a brewing device 1 and a driving device 2. The brewing device 1 includes a bracket 11, and a detachable brewing cup 12 is provided on the bracket 11.

[0028] In a fully automatic coffee machine, the brewing device 1 works in conjunction with the grinding device (not shown) and brewing device 4 within the machine to brew coffee. In its initial position, the brewing device 1 is located directly below the grinding device, collecting ground coffee. Driven by the drive device 2, it then swings to the brewing position, below the brewing device 4. The opening of the brewing cup 12 aligns with the brewing head of the brewing device 4, allowing the head to precisely enter the brewing cup 12 and inject hot water into the ground coffee, completing the brewing process. Once brewing is complete, the brewing device 1 swings back to its initial position to begin the next brewing cycle. In this reciprocating motion, the brewing device 1 repeatedly brews coffee. In coffee machines with a removable brewing cup, the brewing cup 12 is removed and installed when the brewing device 1 is in its initial position. At this point, the brewing device 1 is away from the brewing device 4, and its removal and installation are not restricted by the brewing device 4.

[0029] In the technical solution applied in this embodiment, an elastic reset structure is provided between the bracket 11 and the output shaft 21 of the driving device 2, and the elastic reset structure includes a swinging member 3 arranged between the bracket 11 and the output shaft 21, and an elastic component is provided between the inner side of the swinging member 3 and the output shaft 21, and the elastic component includes a first limiting portion and a second limiting portion, and an elastic element is provided between the first limiting portion and the second limiting portion.

[0030] Specifically, the first limiting portion is arranged on the inner side surface of the swinging member 3, which is a card slot 31 arranged on the inner side surface of the swinging member 3; the second limiting portion is arranged on the end cover 22 of the output shaft 21, which is a card hole 221 arranged on the surface of the end cover 22, and the elastic element is a torsion spring 23, one end of the torsion spring 23 is inserted into the card slot 31, and the other end is inserted into the card hole 221.

[0031] A constraint assembly is provided between the outer side of the swing member 3 and the bracket 11. The constraint assembly includes a shift block 33 arranged on the outer side of the swing member 3 and a stop block 111 arranged on the surface of the bracket 11 facing the output shaft 21. The shift block 33 is located on the path of the stop block 111 moving toward the brewing position.

[0032] Driven by the drive device 2, the brewing device 1 swings from the initial position to the brewing position. The stopper 111 moves synchronously with the bracket 11 and pushes the shifter 33. The pressure on the shifter 33 causes the swing member 3 to rotate accordingly, compressing the torsion spring 23. After brewing is complete, the brewing device 1 swings from the brewing position to the initial position under the drive device 2. The elastic force of the compressed torsion spring 23 is gradually released, causing the swing member 3 to rotate. This rotation of the swing member 3 causes the shifter 33 to continuously push the stopper 111 back until the brewing device 1 reaches the initial position. After reaching the initial position, the drive device 2 stops. Although the driving force of the drive device 2 is lost, the shifter 33 maintains its pressure on the stopper 111 due to the elastic force of the torsion spring 23, limiting the potential shaking of the bracket 11 after the loss of the driving force of the drive device 2 and ensuring that the brewing device 1 accurately remains in the initial position. In this way, the coffee powder required for the next coffee making can be directly collected, or the brewing cup 12 can be disassembled and assembled for cleaning, which can be done conveniently and quickly without the need to power on the drive device 2 to cooperate in the completion.

[0033] In addition, a guide column 32 is provided on the inner side surface of the swinging member 3, and a guide groove 222 is provided on the surface of the end cover 22 for the guide column 32 to move. The moving range of the guide column 32 in the guide groove 222 corresponds to the rotation range of the swinging member 3 and the bracket 11 in the initial position and the brewing position, thereby further enhancing the positioning effect for the initial position and the brewing position through the cooperation between the guide column 32 and the guide groove 222.

[0034] Specifically, a first annular flange 223 extends from the outer edge of the end cap 22 toward the output shaft 21. A protrusion 225 is provided at the bottom of the inner wall of the first annular flange 223, and a hook 226 is provided at the top of the inner wall of the first annular flange 223. The swinging member 3 is disposed within the first annular flange 223 between the protrusion 225 and the hook 226. The inner surface of the swinging member 3 abuts the outer surface of the protrusion 225, and the outer surface of the swinging member 3 engages the hook 226, thereby securing the swinging member 3 to the end cap 22. The protrusion 225 and the hook 226 only restrict the vertical, horizontal, and leftward movement of the swinging member 3, but do not restrict its rotation, thereby ensuring the effective operation of the elastic limiting structure.

[0035] A second annular protrusion 224 extends from the shaft hole of the end cover 22 toward the output shaft 21 , and the torsion spring 23 is sleeved on the second annular protrusion 224 .

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
