Description

Technical Field

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

[0002] Chinese invention patent CN118986128A discloses an automatic coffee machine, in which the moving parts of the brewing device include a fixed sleeve, a moving sleeve, a moving block, and a movable sleeve. One end of the fixed sleeve is fixedly mounted on a support component. The moving sleeve is fitted onto the fixed sleeve and can move relative to the fixed sleeve. The moving block connects to the moving sleeve, and a feeding port is formed between the moving block and the moving sleeve. The movable sleeve is fitted onto the moving sleeve and the moving block and is connected to a drive component. The movable sleeve can push the moving sleeve upward or the moving block downward under the drive of the drive component. In practical applications, the relative fixation of the moving sleeve and the fixed sleeve is achieved by the engagement of a locking block on the fixed sleeve and a locking groove on the moving sleeve. However, the moving sleeve and the fixed sleeve also need to move relative to each other. When the moving sleeve and the fixed sleeve move relative to each other, the locking block needs to disengage from the locking groove. The locking block will wear out when it disengages from the locking groove. Over time, the moving sleeve and the fixed sleeve may not be able to achieve relative fixation through the engagement of the locking block and the locking groove, causing the coffee machine to malfunction.

[0003] Therefore, existing technologies need to be improved and developed. Utility Model Content

[0031] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0035] Firstly, such as Figures 1-6As shown, this utility model provides a brewing device, including a support 1, an extraction cup 2, a driving component 3, a moving component 4, and a water inlet component 5.

[0036] A cavity 11 is formed inside the support member 1. The extraction cup 2 is detachably mounted on the support member 1, with its opening facing the cavity 11. The drive member 3 is mounted on the support member 1. The moving member 4 includes a moving sleeve 41, a moving member 42, and an elastic member 43. The moving sleeve 41 is connected to the drive member 3 and can move within the cavity 11 under the drive of the drive member 3. The moving member 42 is fitted inside the moving sleeve 41, with one end of the moving member 42's pressure-bearing portion 421 movably abutting against the moving sleeve 41. The elastic member 43 is fitted on the moving member 42, with one end of the elastic member 43 abutting against the support platform 411 on the inner sidewall of the moving sleeve 41, and the other end of the elastic member 43 movably abutting against the support portion 422 at the other end of the moving member 42. A water inlet member 5 is provided on the moving member 42, with its outlet facing the opening of the extraction cup 2.

[0037] In practical applications, the brewing apparatus can switch between a first state, a second state, and a third state. When the brewing apparatus is in the first state, the moving part 4 prevents the cavity 11 from communicating with the interior of the extraction cup 2, and one end of the moving part 4 does not extend into the extraction cup 2. When the brewing apparatus is in the second state, the cavity 11 communicates with the interior of the extraction cup 2, and one end of the moving part 4 does not extend into the extraction cup 2. When the brewing apparatus is in the third state, the moving part 4 prevents the cavity 11 from communicating with the interior of the extraction cup 2, and one end of the moving part 4 extends into the extraction cup 2 from the mouth of the extraction cup 2.

[0038] When the coffee machine is in standby mode, the brewing device is in the first state. When coffee brewing begins, the drive component 3 drives the moving sleeve 41 to move upward, switching the brewing device to the second state. At this time, the elastic element 43 is not compressed, and the coffee machine's grinding device grinds the coffee beans. The resulting coffee powder falls into the extraction cup 2 through the powder drop channel formed between the cavity 11 and the moving sleeve 41 and the moving component 42. Then, the drive component 3 drives the moving sleeve 41 to move downward. During the downward movement of the moving sleeve 41, it pushes the pressure part 421 downward, causing the moving sleeve 41 to also move downward, thereby making... The brewing device switches to the third state, tamping and extracting the coffee powder in the extraction cup 2. After extraction, the drive component 3 drives the moving sleeve 41 to move upward. During the upward movement of the moving sleeve 41, it pushes the elastic member 43 upward, causing the other end of the elastic member 43 to abut against the support part 422. As the moving sleeve 41 continues to move upward, the elastic member 43 is compressed. After the moving sleeve 41 moves to its position in the first state, the elastic force of the elastic member 43 drives the moving member 42 to also move to its position in the first state, thus switching the brewing device from the third state to the first state. Specifically, the elastic member 43 can be a spring.

[0039] Compared to using a combination of a card block and a card slot, the above technical solution effectively avoids wear and tear, thus ensuring that the coffee machine can operate normally for a long time.

[0040] In some preferred embodiments, the aforementioned driving component 3 includes a drive motor 31 and a rotating ring 32. The drive motor 31 is mounted on the support member 1, and its output end is connected to a gear. The rotating ring 32 is rotatably mounted on the support member 1. The outer side wall of the rotating ring 32 has teeth that mesh with the gear. The inner side wall of the rotating ring 32 has an internal thread, and the outer side wall of the movable sleeve 41 has an external thread, which is screwed into the internal thread. In specific applications, the drive motor 31 generates a driving force to drive the gear to rotate. The gear drives the rotating ring 32 to rotate through its teeth. The rotating ring 32, through the screwed internal and external threads, drives the movable sleeve 41 to move up and down.

[0041] In some preferred embodiments, the water inlet component 5 includes a water inlet channel 51, a water inlet pipe 52, and a water inlet valve 53. The water inlet channel 51 is formed inside the movable component 42. The outlet end of the water inlet pipe 52 communicates with the inlet end of the water inlet channel 51. The water inlet valve 53 is disposed within the water inlet channel 51. In specific applications, by forming the water inlet channel 51 inside the movable component 42, the structure of the brewing apparatus can be made more compact.

[0042] In some preferred embodiments, the aforementioned water inlet valve 53 includes a plug 531, a movable plug 532, and a reset member 533. The plug 531 is disposed within the water inlet channel 51 and has a through hole 5311 communicating with the water inlet channel 51. The movable plug 532 is movably disposed within the water inlet channel 51 and movably abuts against the reducing section 511 within the water inlet channel 51. The reset member 533 is disposed within the water inlet channel 51, with one end abutting against the plug 531 and the other end abutting against the movable plug 532. In specific applications, when the pressure within the water inlet channel 51 exceeds a predetermined pressure, the pressure pushes the movable plug 532 downwards, forcing the reset member 533 to compress, so that the movable plug 532 no longer blocks the reducing section 511, thereby allowing water to flow sequentially through the water inlet pipe 52, the drain channel 221, and the through hole 5311411 into the extraction cup 2. Specifically, the reset member 533 can be a spring.

[0043] In some preferred embodiments, the movable member 42 is provided with a diverter plate 44, at least a portion of which corresponds to the water inlet channel 51. In specific applications, the diverter plate 44 can divert the water flowing out of the water inlet channel 51, so that the water flows evenly into the extraction cup 2 to achieve a good extraction effect.

[0044] like Figure 7As shown, in some preferred embodiments, the extraction cup 2 includes a cup body 21 and a balancing component 22. The bottom of the cup body 21 has a liquid outlet 211. When the extraction cup 2 is mounted on the support 1, the opening of the cup body 21 corresponds to the moving component 4. The balancing component 22 is movably disposed within the cup body 21 and has a drainage channel 221 that communicates with the liquid outlet 211. In specific applications, when the brewing device switches to the third state to tamp the coffee powder in the extraction cup 2, the balancing component 22 can apply a reverse force to the coffee powder, preventing it from being tamped too tightly, thus improving the subsequent extraction effect.

[0045] Specifically, the aforementioned balancing component 22 includes a movable part 222 and a spring-loaded part 223. The movable part 222 has a limiting part 2221, and the inner wall of the cup body 21 has a blocking part 212. The limiting part 2221 and the blocking part 212 are in movable contact, and a drainage channel 221 is formed on the movable part 222. One end of the spring-loaded part 223 abuts against the movable part 222, and the other end abuts against the inner wall of the bottom of the cup body 21. In practical application, when the moving part 4 tamps the coffee powder, the movable part 222 moves downward under the action of the moving part 4, and the spring-loaded part 223 is compressed. The movable part 222 applies a reverse force to the coffee powder inside the cup body 21, preventing the coffee powder from being compressed too tightly in the coffee extraction cup 2, thus ensuring a good extraction effect during subsequent coffee extraction. Specifically, the spring-loaded part 223 can be a spring.

[0046] In some preferred embodiments, the balancing component 22 further includes a filter 224, which is disposed on the movable component 222 and covers the drainage channel 221. In specific applications, the filter 224 can not only filter out fine powder and impurities in the coffee powder, improving the taste and quality of the coffee, but also prevent coffee powder from clogging the drainage channel 221. Specifically, the structure of the filter 224 can be the same as the structure of the diverter 44.

[0047] In some preferred embodiments, a drain valve 225 is provided within the drain channel 221. By providing a drain valve 225 within the drain channel 221, the drain valve 225 closes when the pressure inside the cup 21 does not reach a predetermined pressure during extraction, and opens when the pressure reaches the predetermined pressure. This allows the coffee powder inside the cup 21 to be fully extracted, further improving the extraction effect. Specifically, the structure and operating principle of the drain valve 225 are the same as those of the water inlet valve 53, and will not be described again here.

[0048] Secondly, this utility model provides a coffee machine, including a grinding device and the brewing device mentioned in the first aspect, wherein the powder outlet of the grinding device is connected to the cavity 11.

[0049] In practical applications, both the grinding and brewing devices are electrically connected to the coffee machine's control system. The coffee machine's control system controls the operation of the grinding and brewing devices to achieve automated control of the coffee machine. Of course, the coffee machine's control system can be any of an industrial computer, PLC, or microcontroller, which will not be elaborated further here.

[0050] In summary, in one or more embodiments of this utility model, the brewing device and coffee machine of this utility model achieve relative fixation between the moving sleeve and the moving part by setting an elastic element between the moving sleeve and the moving part. Compared with the use of a card block and a card slot, this effectively avoids wear and tear, thereby ensuring that the coffee machine can operate normally for a long time.

[0051] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
