Description

Technical Field

[0001] The present invention relates to the field of coffee machines, and in particular to a brewing structure and a coffee machine. Background Art

[0002] In existing coffee brewing devices, coffee grounds are typically fed into the brewing opening through the space between the brewing opening and the tamping device. The distance between the two is generally adjustable. However, even with the maximum adjustment possible, the distance between the two devices is still relatively small. This makes adding coffee grounds into the opening inconvenient, and the grounds can easily fall out or accumulate near the opening. Furthermore, the added coffee grounds tend to form a slope, resulting in unbalanced and uneven tamping. Summary of the Invention

[0003] Based on this, it is necessary to provide a brewing structure and a coffee machine to address the problem that the distance between the powder discharge port and the powder pressing device in the existing coffee machine brewing device is still relatively small after being adjusted to the maximum extent, resulting in inconvenience in operation when putting coffee powder at the powder discharge port, and the coffee powder is easy to fall out or accumulate near the powder discharge port.

[0004] 18. The brewing structure of claim 17, wherein the plurality of brewing components are connected to each other via a plurality of channels, the plurality of channels having a plurality of channels for brewing are connected to each other via a plurality of channels, and the plurality of channels have respective openings and a plurality of openings.

[0005] In a first aspect, the present application discloses a brewing structure in which a driving structure controls the brewing assembly to move to a first position, causing the brewing assembly to extend from a second opening. This significantly increases the adjustable distance between the powder discharge port and the tamping assembly, resolving the problem of limited operating space for powder discharge in conventional brewing structures and simplifying and conveniently adding coffee powder from the powder discharge port. This design effectively prevents coffee powder from falling out or accumulating at the discharge port. It also effectively reduces the slope formed by the deposited coffee powder, ensuring more balanced and uniform tamping by the tamping assembly. An external, vertically continuous movable space serves as an assembly guide and a movable limiter. The tamping assembly can abut against a wall of the brewing space, such as the bottom wall, allowing the tamping assembly to tamp even a small amount of coffee powder within the brewing space, thus enhancing practicality. The driving structure drives the brewing assembly up and down, providing a high degree of automation and enabling the brewing assembly to adjust the distance from the tamping assembly to perform both powder discharge and tamping operations. Preferably, the driving structure is a screw, which is primarily fixed to the upper portion of the support base.

[0006] In one embodiment, the brewing assembly includes a brewing shell and a push-cylinder assembly, the brewing shell is in transmission connection with the drive structure, the brewing shell is provided with the powder discharge port, the push-cylinder assembly is disposed on the brewing shell, and the push-cylinder assembly and the brewing shell enclose the brewing space. The brewing shell is in transmission connection with the drive structure, thereby achieving a high degree of automation and automatically adjusting the movement of the brewing shell relative to the push-cylinder assembly, thereby adjusting the depth of the brewing space.

[0007] In one embodiment, a limiting portion is formed on the support base, the limiting portion is located at the first opening, and further includes a limiting convex buckle, the limiting convex buckle is arranged on the push cylinder assembly, the limiting convex buckle can abut or separate from the limiting portion, when the limiting convex buckle abuts against the limiting portion, the driving structure can drive the brewing shell to move relative to the push cylinder assembly, and when the limiting convex buckle separates from the limiting portion, the driving structure can drive the brewing assembly to move relative to the support base. By setting the limiting convex buckle on the push cylinder assembly, the limiting portion can effectively limit the freedom of the push cylinder assembly when the limiting convex buckle abuts against the limiting portion, so that the push cylinder assembly remains relatively fixed when the brewing shell moves relative to the push cylinder assembly under the control of the driving structure, thereby adjusting the depth of the brewing space formed by the brewing shell and the push cylinder assembly, facilitating the operation of placing powder and scraping powder, for example, when powder needs to be placed, the depth of the brewing space is increased, and when powder needs to be scraped, the depth of the brewing space is reduced. When the limiting convex buckle is separated from the limiting part, the brewing shell and the push cylinder assembly move together relative to the support base under the control of the driving structure, which is suitable for the operation process of adjusting the distance between the powder discharge port and the powder pressing assembly, and is also suitable for the overall rising to realize the powder pressing operation.

[0008] In one embodiment, the push cylinder assembly is provided with an adapter hole, and the limiting convex buckle is provided on the push cylinder assembly and is located at the adapter hole, and the limiting convex buckle can move relative to the push cylinder assembly. The limiting convex buckle can be retracted toward the adapter hole, so that the limiting portion no longer limits the movement of the push cylinder assembly, so that the push cylinder assembly and the brewing shell can move together under the control of the driving structure, and realize the operation of adjusting the distance between the powder discharge port and the powder pressing assembly or the overall rise to realize the powder pressing operation. By moving the limiting convex buckle at a specific position, the limiting convex buckle and the limiting portion are abutted, thereby limiting the freedom of the push cylinder assembly, so that the brewing shell can move relative to the push cylinder assembly to adjust the depth value of the brewing space.

[0009] In one embodiment, there are multiple limiting protrusions, all of which are provided on the push-cylinder assembly. The multiple limiting protrusions are spaced apart along the circumference of the push-cylinder assembly, and all of the limiting protrusions are capable of abutting or separating against the limiting portion. By enabling the multiple limiting protrusions to abut against the limiting portion, the reliability and stability of the abutment between the limiting protrusions and the limiting portion are improved, thereby achieving a better effect of relatively fixing the push-cylinder assembly.

[0010] In one embodiment, there are two limiting protrusions, both of which are disposed on the push cylinder assembly and are arranged opposite each other. Furthermore, a first elastic member is included, one end of the first elastic member abuts against one of the two limiting protrusions, and the other end of the first elastic member abuts against the other of the two limiting protrusions. By abutting the two ends of the first elastic member against different limiting protrusions, the limiting protrusions can automatically pop out after retracting toward the adapting hole, thereby achieving a high degree of automation.

[0011] In one embodiment, a second elastic member is further included, with both ends of the second elastic member being connected to the position-limiting buckle and the push-cylinder assembly, respectively. By connecting both ends of the second elastic member to the position-limiting buckle and the push-cylinder assembly, the position-limiting buckle can be automatically ejected after being retracted toward the adapting hole, thereby achieving a high degree of automation.

[0012] In one embodiment, the limiting portion is provided with a first limiting surface and a second limiting surface, the first limiting surface facing the activity space, the limiting convex buckle can be abutted against the first limiting surface or the second limiting surface of the limiting portion, and when the limiting convex buckle abuts against the first limiting surface, the driving structure can drive the brewing shell to move relative to the push cylinder assembly in a first direction, and when the limiting convex buckle abuts against the second limiting surface, the driving structure can drive the brewing shell to move relative to the push cylinder assembly in a second direction, the first direction being opposite to the second direction. When the brewing shell moves relative to the push cylinder assembly in a first direction, such as an upward direction, the limiting convex buckle abuts against the first limiting surface of the limiting portion, such as the bottom surface of the limiting portion, at this time, the depth value of the brewing space increases, facilitating the powder releasing operation; when the brewing shell moves relative to the push cylinder assembly in a second direction, such as a downward direction, the limiting convex buckle abuts against the second limiting surface of the limiting portion, such as the top surface of the limiting portion, at this time, the depth value of the brewing space decreases, facilitating the powder scraping operation.

[0013] In one embodiment, the limiting buckle is provided with a first buckle inclined surface and a second buckle inclined surface, the first buckle inclined surface can be abutted against the first limiting surface, and when the first buckle inclined surface abuts against the first limiting surface, the driving structure can drive the brewing shell to move toward the first direction relative to the push cylinder assembly, and the second buckle inclined surface can be abutted against the second limiting surface, and when the second buckle inclined surface abuts against the second limiting surface, the driving structure can drive the brewing shell to move toward the second direction relative to the push cylinder assembly. Because the first buckle inclined surface can abut against the first limiting surface and the second buckle inclined surface can abut against the second limiting surface, the limiting buckle can be retracted toward the adapter hole, and the push cylinder assembly can overcome the restriction of its freedom by the limiting portion, thereby realizing the synchronous movement of the brewing shell and the push cylinder assembly, and realizing the operation of adjusting the distance between the powder discharge port and the powder pressing assembly or the overall lifting to realize the powder pressing operation.

[0014] In one embodiment, when the brewing shell moves, the brewing shell can be located at least in the third and fourth positions of the push-cylinder assembly. When the brewing shell is located in the third position of the push-cylinder assembly, the depth of the brewing space is L1, and when the brewing shell is located in the fourth position of the push-cylinder assembly, the depth of the brewing space is L2, and L1 is greater than L2. The depth of the brewing space can be adjusted by adjusting the relative position of the brewing shell and the push-cylinder assembly, facilitating the operations of placing and scraping powder. For example, the depth of the brewing space is increased when powder needs to be placed, and decreased when powder needs to be scraped.

[0015] In one embodiment, when the brewing assembly is in the first position, the brewing housing is in the third position of the push-cylinder assembly, the brewing housing abuts against the limiting portion, and the push-cylinder assembly extends from the second opening. When the brewing assembly is in the first position, the brewing housing has moved to the push-cylinder assembly limiting position, i.e., the overall length of the brewing assembly is at its maximum, the brewing housing abuts against the limiting portion, and the brewing assembly has a brewing space of maximum depth and is farthest from the powder pressing space, facilitating the powder releasing operation.

[0016] In one embodiment, when the brewing assembly is in the second position, the brewing housing is in the third position of the push cylinder assembly and the powder pressing assembly abuts against the bottom wall of the brewing space. When the brewing assembly is in the second position, the brewing housing has moved to the push cylinder assembly limit position, i.e., the overall length of the brewing assembly is maximized and the brewing space is deepest, thereby achieving powder pressing.

[0017] In one embodiment, when the brewing housing is located at the fourth position of the push cylinder assembly, the push cylinder assembly is located at the powder discharge port. When the push cylinder assembly is located at the powder discharge port, it is convenient to scrape off the powder residue.

[0018] In one embodiment, the support base includes a support base body and a base, the powder pressing assembly is disposed on the support base body, the support base body is provided with the accommodating space, the base is disposed on the support base body, the base is provided with the first opening, the movable space, and the second opening, and the limiting portion is disposed on the base.

[0019] In one embodiment, the invention further comprises a water inlet joint and a water outlet joint, both of which are arranged on the support base, and are located at or near the top of the support base. The water inlet joint is provided with an input port, and the water outlet joint is provided with an output port. The pressed powder assembly is provided with a liquid passage cavity, and further comprises a water inlet pipe. The input port, the water inlet pipe, the brewing space, the liquid passage cavity, and the output port are sequentially connected, and the water inlet pipe is located inside the support base. By locating the water inlet pipe inside the support base, the water inlet pipe is hidden, the layout is more reasonable, and the structure is more compact. The water inlet joint and the water outlet joint are assembled downwards, making it convenient to connect the pipes.

[0020] In one embodiment, the powder pressing assembly is movably mounted on the support base and is movable relative to the support base. The ability of the powder pressing assembly to move relative to the support base, such as forward and backward or left and right movement, allows the powder pressing assembly to accurately press the coffee powder within the brewing space, thereby improving tolerance, lowering assembly precision requirements, simplifying assembly, and increasing yield.

[0021] In one embodiment, a powder scraping assembly is further included, comprising a rotating rod, a scraper structure, and a transmission unit. The rotating rod is disposed on the brewing assembly, and the scraper structure and transmission unit are both disposed on the rotating rod and are located at either end of the rotating rod. The scraper structure is disposed adjacent to the powder discharge port and is used to scrape away powder residue adhering to the brewing assembly. The support base is provided with a transmission space, and a rib is formed on the support base. The rib is located within the transmission space, and the rib can abut or separate from the transmission unit. When the rib abuts the transmission unit, the transmission unit can rotate relative to the brewing assembly. When the brewing assembly moves downward, the powder scraping assembly also moves downward with the brewing assembly. The transmission unit of the powder scraping assembly enters the transmission space and abuts against the rib. The transmission unit is curved, and the curved portion of the transmission unit abuts against the rib. The abutting force of the rib drives the transmission unit to rotate, and the powder scraping assembly automatically rotates as a whole to perform the powder scraping operation, resulting in a high degree of automation.

The specific operating steps of the brewing structure are as follows: First, the limiting convex buckle on the push cylinder assembly is abutted against the limiting part of the support seat, and the brewing shell moves upward relative to the push cylinder assembly under the drive of the driving structure until the brewing shell moves to the point where it can no longer move upward relative to the push cylinder assembly, at which time the brewing space is the largest; Second, the brewing shell and the push cylinder assembly move downward as a whole, and can be moved as a whole until the brewing shell and the limiting part are abutted, at which time the push cylinder assembly extends from the second opening and the distance between the powder release port and the powder pressing assembly is the largest, and the powder release operation can be performed; Third, the brewing shell and the push cylinder assembly move upward as a whole, and the first convex buckle inclined surface of the limiting convex buckle abuts against the bottom surface of the limiting part and enables the brewing assembly as a whole to overcome the freedom restriction imposed on it by the limiting part.

[0054] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0056] Example 1

[0057] like Figure 1-21 As shown, this embodiment discloses a brewing structure, comprising: a support base 1, wherein the support base 1 is provided with an activity space 101 and a storage space 102, wherein the support base 1 is provided with a first opening 103 and a second opening 104, wherein the first opening 103 and the second opening 104 are both connected to the activity space 101; a powder pressing component 2, wherein the powder pressing component 2 is arranged on the support base 1; a driving structure 3, wherein the driving structure 3 is arranged on the support base 1 and is located at the storage space 102; a brewing component 4, wherein the brewing component 4 is connected to the driving structure 3 The brewing component 4 is connected by transmission, and is provided with a brewing space 401 and a powder discharge port 402. The powder discharge port 402 is communicated with the brewing space 401. The driving structure 3 can drive the brewing component 4 to move relative to the support base 1. The brewing component 4 has at least a first position and a second position when moving relative to the support base 1. When the brewing component 4 is in the first position, part of the brewing component 4 extends from the second opening 104. When the brewing component 4 is in the second position, the powder pressing component 2 is against the space wall of the brewing space 401.

[0058] In a first aspect, the present application discloses a brewing structure. When the brewing assembly 4 is controlled by a drive mechanism 3 to move to a first position, the brewing assembly 4 extends from a second opening 104, significantly increasing the adjustable distance between the powder discharge port 402 and the tamping assembly 2. This solves the problem of limited operating space for powder discharge in conventional brewing structures, making the process of adding coffee powder from the powder discharge port 402 simpler and more convenient. This design effectively prevents coffee powder from falling out or accumulating at the powder discharge port 402. It also effectively reduces the slope formed by the deposited coffee powder, ensuring more balanced and uniform tamping by the tamping assembly 2. The external, vertically continuous movable space 101 serves as an assembly guide and a movable limiter. The tamping assembly 2 can abut against the walls of the brewing space 401, such as the bottom wall, allowing the tamping assembly 2 to tamping even a small amount of coffee powder placed in the brewing space 401, thus enhancing practicality. The brewing assembly 4 is driven up and down by the drive mechanism 3, providing a high degree of automation, allowing the brewing assembly 4 to adjust the distance from the tamping assembly 2 to perform both powder discharge and tamping operations. Preferably, the driving structure 3 is a screw, which is mainly fixed on the upper part of the support base 1 under force.

[0059] like Figure 1 and Figure 3-10 As shown, in addition to the features of the above embodiment, this embodiment further defines: the brewing assembly 4 includes a brewing shell 41 and a push cylinder assembly 42, the brewing shell 41 is transmission-connected to the driving structure 3, the brewing shell 41 is provided with the powder discharge port 402, the push cylinder assembly 42 is disposed on the brewing shell 41, and the push cylinder assembly 42 and the brewing shell 41 enclose the brewing space 401. Through the transmission connection between the brewing shell 41 and the driving structure 3, the degree of automation is high, and the movement of the brewing shell 41 relative to the push cylinder assembly 42 can be automatically adjusted, thereby adjusting the depth of the brewing space 401.

[0060] like Figure 1-2 and Figure 6-8As shown, in addition to the features of the above embodiments, this embodiment further defines: a limiting portion 121 is formed on the support seat body 1, the limiting portion 121 is located at the first opening 103, and also includes a limiting protrusion 43, the limiting protrusion 43 is arranged on the push cylinder assembly 42, the limiting protrusion 43 can be against or separated from the limiting portion 121, when the limiting protrusion 43 is against the limiting portion 121, the driving structure 3 can drive the brewing shell 41 to move relative to the push cylinder assembly 42, and when the limiting protrusion 43 is separated from the limiting portion 121, the driving structure 3 can drive the brewing assembly 4 to move relative to the support seat body 1. The limiting buckle 43 is provided on the push cylinder assembly 42. When the limiting buckle 43 abuts against the limiting portion 121, the limiting portion 121 can effectively limit the freedom of the push cylinder assembly 42, so that the push cylinder assembly 42 remains relatively fixed when the brewing shell 41 moves relative to the push cylinder assembly 42 under the control of the driving structure 3. Therefore, the depth of the brewing space 401 enclosed by the brewing shell 41 and the push cylinder assembly 42 can be adjusted, facilitating the operation of releasing and scraping powder. For example, when powder needs to be released, the depth of the brewing space 401 is increased, and when powder needs to be scraped, the depth of the brewing space 401 is reduced. When the limiting buckle 43 is separated from the limiting portion 121, the brewing shell 41 and the push cylinder assembly 42 move together relative to the support body 1 under the control of the driving structure 3, which is suitable for the operation process of adjusting the distance between the powder discharge port 402 and the powder pressing assembly 2, and is also suitable for the overall lifting to achieve powder pressing operation.

[0061] like Figure 2-3 、 Figure 6-10 and Figure 12 As shown, in addition to the features of the above embodiment, this embodiment further defines: the push cylinder assembly 42 is provided with an adapting hole 403, and the limiting protrusion 43 is disposed on the push cylinder assembly 42 and located at the adapting hole 403. The limiting protrusion 43 is movable relative to the push cylinder assembly 42. By retracting the limiting protrusion 43 toward the adapting hole 403, the limiting portion 121 no longer restricts the movement of the push cylinder assembly 42. As a result, the push cylinder assembly 42 and the brewing housing 41 can move together under the control of the drive structure 3, thereby adjusting the distance between the powder discharge port 402 and the powder pressing assembly 2 or raising the entire assembly to achieve powder pressing. By moving the limiting protrusion 43 at a specific position, the limiting protrusion 43 abuts against the limiting portion 121, limiting the freedom of the push cylinder assembly 42, allowing the brewing housing 41 to move relative to the push cylinder assembly 42 to adjust the depth of the brewing space 401.

[0062] like Figure 2-3 、 Figure 6-10 and Figure 12As shown, in addition to the features of the above embodiment, this embodiment further defines: there are multiple limiting protrusions 43, multiple limiting protrusions 43 are provided on the push cylinder assembly 42, multiple limiting protrusions 43 are spaced along the circumference of the push cylinder assembly 42, and multiple limiting protrusions 43 can abut against or separate from the limiting portion 121. Because multiple limiting protrusions 43 can abut against the limiting portion 121, the reliability and stability of the abutment between the limiting protrusions 43 and the limiting portion 121 are improved, so that the push cylinder assembly 42 is better fixed relatively.

[0063] like Figure 10 and Figure 13 As shown, in addition to the features of the above embodiment, this embodiment further defines: there are two limiting protrusions 43, both of which are provided on the push cylinder assembly 42 and are arranged opposite each other, and further includes a first elastic member 44, one end of which abuts against one of the two limiting protrusions 43, and the other end of which abuts against the other of the two limiting protrusions 43. By abutting the two ends of the first elastic member 44 against different limiting protrusions 43, the limiting protrusions 43 can automatically pop out after being retracted toward the adapting hole 403, thereby achieving a high degree of automation.

[0064] In addition to the features of the above embodiment, this embodiment further comprises a second elastic member, the ends of which are respectively connected to the position-limiting protrusion 43 and the push-cylinder assembly 42. By connecting the ends of the second elastic member to the position-limiting protrusion 43 and the push-cylinder assembly 42, the position-limiting protrusion 43 can automatically pop out after retracting toward the adapting hole 403, thereby achieving a high degree of automation.

[0065] like Figure 2 、 Figure 18 and Figure 21As shown, in addition to the features of the above embodiments, this embodiment further defines: the limiting portion 121 is provided with a first limiting surface 105 and a second limiting surface 106, the first limiting surface 105 faces the activity space 101, the limiting protrusion 43 can be abutted against the first limiting surface 105 or the second limiting surface 106 of the limiting portion 121, when the limiting protrusion 43 abuts against the first limiting surface 105, the driving structure 3 can drive the brewing shell 41 to move relative to the push cylinder assembly 42 toward a first direction, when the limiting protrusion 43 abuts against the second limiting surface 106, the driving structure 3 can drive the brewing shell 41 to move relative to the push cylinder assembly 42 toward a second direction, and the first direction is opposite to the second direction. When the brewing shell 41 moves in a first direction, for example, an upward direction, relative to the push cylinder assembly 42, the limiting protrusion 43 is against the first limiting surface 105 of the limiting part 121, for example, the bottom surface of the limiting part 121. At this time, the depth value of the brewing space 401 increases, which is convenient for the powder releasing operation; when the brewing shell 41 moves in a second direction, for example, a downward direction, relative to the push cylinder assembly 42, the limiting protrusion 43 is against the second limiting surface 106 of the limiting part 121, for example, the top surface of the limiting part 121. At this time, the depth value of the brewing space 401 is reduced, which is convenient for the powder scraping operation.

[0066] like Figure 10-13 As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: the limiting convex buckle 43 is provided with a first convex buckle inclined surface 404 and a second convex buckle inclined surface 405, the first convex buckle inclined surface 404 can be abutted against the first limiting surface 105, when the first convex buckle inclined surface 404 abuts against the first limiting surface 105, the driving structure 3 can drive the brewing shell 41 to move relative to the push cylinder assembly 42 toward the first direction, the second convex buckle inclined surface 405 can be abutted against the second limiting surface 106, when the second convex buckle inclined surface 405 abuts against the second limiting surface 106, the driving structure 3 can drive the brewing shell 41 to move relative to the push cylinder assembly 42 toward the second direction. The first convex buckle inclined surface 404 can be abutted against the first limiting surface 105, and the second convex buckle inclined surface 405 can be abutted against the second limiting surface 106, so that the limiting convex buckle 43 can be retracted toward the adapter hole 403, and the push cylinder assembly 42 can overcome the restriction of its freedom by the limiting portion 121, thereby realizing the synchronous movement of the brewing shell 41 and the push cylinder assembly 42, and realizing the distance adjustment operation between the powder discharge port 402 and the powder pressing assembly 2 or the overall lifting to realize the powder pressing operation.

[0067] like Figure 9-10As shown, in addition to the features of the above embodiment, this embodiment further defines that: when the brewing shell 41 moves, the brewing shell 41 can be located at least in the third position and the fourth position of the push cylinder assembly 42; when the brewing shell 41 is located at the third position of the push cylinder assembly 42, the depth value of the brewing space 401 is L1; when the brewing shell 41 is located at the fourth position of the push cylinder assembly 42, the depth value of the brewing space 401 is L2, and L1 is greater than L2. The depth value of the brewing space 401 can be adjusted by adjusting the relative position of the brewing shell 41 and the push cylinder assembly 42, facilitating the operations of placing and scraping powder. For example, when powder needs to be placed, the depth value of the brewing space 401 is increased, and when powder needs to be scraped, the depth value of the brewing space 401 is reduced.
