Technical Field

[0001] This invention relates to a brewer structure with a manual knob that allows the brewer piston to move up and down. The invention belongs to the field of fully automatic coffee machine technology, specifically to a brewer structure with a manual knob that allows the brewer piston to move up and down. Background Technology

[0002] In modern kitchen life, fully automatic coffee machines have become a common and widely popular choice for beverage preparation due to their convenience and efficiency, eliminating the need for manual grinding and extraction. However, the built-in brewing unit of traditional fully automatic coffee machines has structural and functional limitations. The core problem is that after the coffee is brewed, the filter inside the brewing chamber is often located at the bottom, making it difficult to reach during cleaning and increasing the difficulty of cleaning and the risk of residue.

[0003] Even in some brewers where the filter is located at the top, the lack of a dedicated lifting mechanism prevents the piston position from being flexibly adjusted according to cleaning needs, resulting in a poor user experience. Long-term dirt residue not only affects the hygiene of the appliance but may also reduce the performance and lifespan of the coffee machine, leading to user complaints and failing to meet users' needs for convenient brewer cleaning. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A brewing device structure with a manual knob that allows the brewing piston to move up and down includes a brewing end and a mounting shell. The brewing end has a brewing chamber inside, and a piston is slidably installed inside the brewing chamber. A U-shaped bracket connected to the bottom end of the piston is installed inside the mounting shell, and an adjustment frame that can drive the U-shaped bracket to move up and down is provided in the mounting shell.

[0007] As a preferred embodiment of this utility model, the piston and the U-shaped bracket are connected by bolts, and the inner sides of the mounting shell are equipped with limiting plates that can prevent the U-shaped bracket from shifting. A guide strip is installed on one side of the U-shaped bracket, and a guide groove that cooperates with the guide strip is provided inside the mounting shell.

[0008] As a preferred embodiment of the present invention, the adjustment frame includes a mounting shaft, one end of which extends through and to the outside of the mounting housing and is connected to a knob, the other end of which is supported by a bearing seat, and a gear is sleeved on the mounting shaft inside the U-shaped bracket.

[0009] As a preferred embodiment of this utility model, a rack is installed on one side of the inside of the U-shaped bracket, and the rack is meshed with a gear.

[0010] As a preferred embodiment of this utility model, the surface of the knob is provided with an indicator arrow, and the mounting shell is provided with position markers at positions corresponding to the outside of the knob.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Cleaning is convenient and efficient: The piston can be raised and lowered by manually turning the knob. When the piston is at the bottom after operation, turn the knob to the corresponding mark and the piston can be pushed to the top, making it convenient for users to directly clean the filter and surrounding dirt without external force or special tools.

[0013] Precise installation alignment: The indicator arrow on the knob, along with the position marker, clearly indicates the exact position of the brewer when it is removed. After cleaning, simply turn the knob in the opposite direction to reset it. Reinstallation is easy and alignment is straightforward, solving the problem of difficult alignment after cleaning traditional brewers.

[0014] Stable and reliable structure: The combination of the limiting plate, guide strip and guide groove effectively prevents the U-shaped bracket from shifting, and the gear and rack transmission structure ensures smooth piston lifting and lowering without affecting the coffee machine's autonomous operation function.

[0015] Simple and easy to operate: The knob is located in an easily accessible position on the front of the brewer, with clear markings, allowing for adjustment without professional knowledge, lowering the barrier to entry for users and enhancing the overall user experience.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A brewer structure with a manual knob that allows the brewer piston to move up and down includes a brewing end 1 and a mounting shell 2. The brewing end 1 has a brewing chamber 3 inside, and a piston 4 is slidably mounted inside the brewing chamber 3. The piston 4 is used to cooperate with the brewing chamber 3 to complete the coffee extraction process.

[0024] A U-shaped bracket 5 is installed inside the mounting shell 2. The bottom end of the piston 4 is fixedly connected to the U-shaped bracket 5 by bolts 7 to ensure synchronous movement. Limiting plates 16 are fixedly installed on both sides inside the mounting shell 2. The limiting plates 16 fit against the sides of the U-shaped bracket 5 to limit the left and right offset of the U-shaped bracket 5. A guide strip 17 is integrally formed on one side of the U-shaped bracket 5. A guide groove adapted to the guide strip 17 is opened inside the mounting shell 2. The guide strip 17 is embedded in the guide groove and can slide along the groove to further ensure the stability of the U-shaped bracket 5 when moving up and down.

[0025] An adjustment bracket 6 is provided in the mounting housing 2. The adjustment bracket 6 includes a mounting shaft 9. One end of the mounting shaft 9 passes through the side wall of the mounting housing 2 and extends to the outside. A knob 11 is fixedly connected to this end. An indicator arrow 13 is printed on the surface of the knob 11. A position mark 14 is engraved on the mounting housing 2 corresponding to the position of the knob 11. The position mark 14 can be set as "TOP" (top) and "BOTTOM" (bottom), or it can be a number or other identification form to facilitate the user to identify the position of the piston 4.

[0026] The other end of the mounting shaft 9 is connected to the inner wall of the mounting housing 2 through the bearing seat 12. The bearing seat 12 provides stable support for the mounting shaft 9 and reduces friction during rotation. A gear 10 is fixedly sleeved on the mounting shaft 9 inside the U-shaped bracket 5. A rack 8 is fixedly installed on one side of the inside of the U-shaped bracket 5. The rack 8 meshes with the gear 10 to form a gear and rack transmission mechanism.

[0027] Working principle and usage of this utility model:

[0028] When the coffee machine is working normally, the adjustment bracket 6 does not participate in autonomous operation. The piston 4 moves with the coffee machine's working program. After the work is completed, the piston 4 is at the bottom of the brewing chamber 3. At this time, the indicator arrow 13 on the knob 11 points to the "BOTTOM" position mark 14.

[0029] When cleaning is required, the user removes the brewer and manually turns the knob 11, which drives the mounting shaft 9 and gear 10 to rotate. The gear 10 meshes with the rack 8, driving the U-shaped bracket 5 to move upward along the guide groove, which in turn drives the piston 4 to rise in the brewing chamber 3 until the indicator arrow 13 points to the "TOP" position. At this point, the piston 4 reaches the top of the brewing chamber 3, and the filter and surrounding dirt are fully exposed, which the user can clean directly.

[0030] After cleaning, turn knob 11 in the opposite direction, gear 10 rotates in the opposite direction, and the U-shaped bracket 5 moves downward through rack 8. Piston 4 returns to the bottom of brewing chamber 3, and indicator arrow 13 returns to "BOTTOM". Then, align the brewer and install it back into the coffee machine. The operation is simple and efficient.

[0031] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
