Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a coffee powder conveying device and a coffee machine. Background Technology

[0002] Traditional coffee machines typically use a coffee grounds conveyor to automatically transport coffee grounds from the grinder to the brewing unit. This conveyor usually includes a drive plate, and coffee grounds tend to adhere to its surface. However, traditional coffee machines lack a mechanism to actively clean the coffee grounds adhering to the drive plate, making the removal of residual coffee grounds more difficult. Utility Model Content

[0003] Therefore, it is necessary to provide a coffee powder conveying device and coffee machine to address the problem that traditional coffee machines lack a structure for actively cleaning coffee powder adhering to the transmission plate, which makes cleaning coffee powder more difficult.

[0004] A coffee powder conveying device includes: a support assembly having an installation cavity and a limiting port communicating with the installation cavity, and a powder drop outlet; a powder conveying assembly movably disposed on the support assembly and located at the limiting port, extending toward the installation cavity; and a transmission plate assembly movably disposed on the support assembly, movable relative to the support assembly, wherein coffee powder attached to the transmission plate assembly can fall toward the powder drop outlet when the transmission plate assembly moves relative to the support assembly, the transmission plate assembly being drively connected to the powder conveying assembly, and capable of driving the powder conveying assembly to move relative to the support assembly at the limiting port.

[0005] The first aspect of this application discloses a coffee powder conveying device. A transmission plate assembly drives a powder conveying component to move relative to a support assembly, enabling the powder conveying component to deliver coffee powder ground by the grinding assembly to the brewing assembly. During the movement of the transmission plate assembly relative to the support assembly to perform the coffee powder conveying function, coffee powder adhering to the surface of the transmission plate assembly is directly scraped off or shaken off, and the fallen coffee powder is discharged through the powder outlet. This design automatically cleans the coffee powder adhering to the surface of the transmission plate assembly, making the cleaning of residual coffee powder simpler and more convenient, effectively preventing coffee powder residue and accumulation on key transmission components, and preventing residual coffee powder from obstructing the movement of the transmission plate assembly or causing it to jam. The coffee powder conveying device disclosed in this application integrates powder conveying and cleaning functions by simultaneously conveying and cleaning the powder, avoiding the need for users to frequently manually clean residual coffee powder from transmission components, and achieving a high degree of automation.

[0006] In one embodiment, the transmission plate assembly has a first side facing the limiting opening. The first side abuts against the support assembly. When the transmission plate assembly moves relative to the support assembly, coffee powder adhering to the first side can fall towards the powder discharge port. Through the abutment between the first side of the transmission plate assembly and the support assembly, the continuous relative movement between the first side of the transmission plate assembly and the support assembly during movement generates friction that scrapes off the coffee powder adhering to the first side, resulting in an automatic and efficient cleaning effect.

[0007] In one embodiment, the support assembly includes a support member and a cover plate. The powder feeding assembly is disposed on the support member. The support member has the mounting cavity and the limiting opening. The cover plate is disposed on the support member and is located on the side of the support member. The transmission plate assembly is located between the support member and the cover plate. A first side of the transmission plate assembly abuts against the support member. The transmission plate assembly has a second side opposite to the first side, which abuts against the cover plate. When the transmission plate assembly moves relative to the support assembly, the coffee powder attached to the second side can fall towards the powder discharge port. By having the first side of the transmission plate assembly abut against the support member and the second side against the cover plate, when the transmission plate assembly moves, the first and second sides rub against the support member and the cover plate respectively, which can simultaneously and efficiently scrape off the coffee powder attached to both sides, resulting in a more comprehensive cleaning range and no dead corners. This design can also prevent the cleaning of coffee powder attached to the second side if necessary.

[0008] In one embodiment, a rib is formed on the support member, located on the side of the limiting opening. The rib abuts against the first side of the transmission plate assembly, and a powder-passing gap is formed between the transmission plate assembly and the support member. This powder-passing gap communicates with both the limiting opening and the powder-discharging port. The line contact between the rib and the first side of the transmission plate assembly increases the local contact pressure, more effectively scraping off adhering coffee powder and improving the cleaning ability for residual coffee powder. Furthermore, the rib's design creates a powder-passing gap between the transmission plate assembly and the support member, allowing coffee powder scraped from the first side to fall towards the powder-discharging port.

[0009] In one embodiment, the support member includes a support housing and a powder dispensing housing. The powder conveying assembly is disposed on the support housing. The support housing has the mounting cavity and the limiting opening. The powder dispensing housing is disposed on the support member and is located on the side of the support housing. The powder dispensing housing has the powder drop outlet, or the powder dispensing housing and the support housing enclose each other to form the powder drop outlet. The support housing allows for stable assembly of the transmission assembly, enabling the transmission plate assembly to move stably to convey coffee powder. The powder dispensing housing allows coffee powder that falls onto the surface of the transmission plate assembly to be discharged from the powder drop outlet, achieving the functions of powder conveying and powder cleaning.

[0010] In one embodiment, the powder dispensing housing includes a powder dispensing section and a separating section. The powder dispensing section is disposed on the supporting housing, and both ends of the separating section are connected to the powder dispensing section and the supporting housing, respectively. The powder dispensing section, the separating section, and the supporting housing together form the powder discharge port. The powder dispensing section ensures that coffee powder scraped from the surface of the transmission plate assembly can be discharged from the powder discharge port, preventing coffee powder from accumulating on the surface of the transmission plate assembly and causing more troublesome subsequent cleaning and maintenance. The separating section enhances the structural strength of the powder dispensing housing, preventing deformation under external forces.

[0011] In one embodiment, the powder feeding assembly includes a support member and a powder feeding member. The support member is disposed on the support assembly and located at the limiting opening, abutting against the bottom wall of the limiting opening. The powder feeding member is disposed on the support member and located at the limiting opening, abutting against the top wall of the limiting opening. The powder feeding member is driven in conjunction with the transmission plate assembly. The support member and the powder feeding member can move together relative to the support assembly under the control of the transmission plate assembly. When the support member and the powder feeding member move relative to the support assembly, the coffee powder at the limiting opening can fall towards the powder dropper. By having the support member abut against the bottom wall of the limiting port and the powder conveying member abut against the top wall of the limiting port, when the support member and the powder conveying member move synchronously under the drive of the transmission plate assembly, they can simultaneously scrape the top and bottom of the limiting port, thoroughly removing the coffee powder adhering to the inner wall of the limiting port. This effectively prevents powder residue from remaining and accumulating in the limiting port, allowing for timely handling of any residual coffee powder in the limiting port.

[0012] In one embodiment, a drive assembly is further included, disposed on the support assembly and drivenly connected to the transmission plate assembly. The drive assembly is capable of driving the transmission plate assembly to move relative to the support assembly. Through the drive assembly's connection to the transmission plate assembly, the transmission plate assembly can be actively and precisely driven to perform a predetermined movement stroke. This design ensures that the delivery of coffee powder and the self-cleaning process of the transmission plate assembly and the limiting port require no manual intervention, improving the automation level and ease of operation of the equipment.

[0013] In one embodiment, the cavity wall of the mounting cavity has a first limiting plane and a second limiting plane disposed opposite to each other, and further includes a brewing component. The brewing component is disposed on the support component and located within the mounting cavity, with opposite sides of the brewing component abutting against the first limiting plane and the second limiting plane, respectively. By having opposite sides of the brewing component abut against the first and second limiting planes, compared to traditional stepped or arc-shaped abutment surfaces, this design can avoid or reduce steam leakage from the brewing component. Furthermore, it ensures stable installation of the brewing component, enabling it to operate stably.

[0014] A coffee machine includes: the coffee powder conveying device described above.

[0015] The second aspect of this application discloses a coffee machine in which a transmission plate assembly of a coffee powder conveying device moves relative to a support assembly, and residual coffee powder adhering to the surface of the transmission plate assembly can be automatically scraped and cleaned, thereby automatically and instantly cleaning the attached powder particles. Users do not need to manually clean the residual coffee powder, which has a high degree of automation and ensures the stable operation of the powder conveying process. Attached Figure Description

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide 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.

[0039] Example 1

[0040] like Figure 1-14 As shown, this embodiment discloses a coffee powder conveying device, including: a support assembly 1, which has an installation cavity 101 and a limiting port 102, the limiting port 102 communicating with the installation cavity 101, and a powder drop port 103; a powder conveying assembly 2, which is movably disposed on the support assembly 1 and located at the limiting port 102, extending toward the installation cavity 101; and a transmission plate assembly 3, which is movably disposed on the support assembly 1, and is movable relative to the support assembly 1. When the transmission plate assembly 3 moves relative to the support assembly 1, the coffee powder attached to the transmission plate assembly 3 can fall toward the powder drop port 103. The transmission plate assembly 3 is drively connected to the powder conveying assembly 2, and can drive the powder conveying assembly 2 to move relative to the support assembly 1 at the limiting port 102.

[0041] The first aspect of this application discloses a coffee powder conveying device. A transmission plate assembly 3 drives a powder conveying assembly 2 to move relative to a support assembly 1, enabling the powder conveying assembly 2 to convey coffee powder ground by a grinding assembly 6 to a brewing assembly 5. During the movement of the transmission plate assembly 3 relative to the support assembly 1 to perform the coffee powder conveying function, coffee powder adhering to the surface of the transmission plate assembly 3 is directly scraped off or shaken off, and the fallen coffee powder is discharged through the powder discharge port 103. This design automatically cleans the coffee powder adhering to the surface of the transmission plate assembly 3, making the cleaning of residual coffee powder simpler and more convenient, effectively preventing coffee powder residue and accumulation on key transmission components, and preventing residual coffee powder from obstructing the movement of the transmission plate assembly 3 or causing it to jam. The coffee powder conveying device disclosed in this application integrates powder conveying and cleaning functions by simultaneously conveying and cleaning the powder, avoiding the need for users to frequently manually clean residual coffee powder from transmission components, and achieving a high degree of automation.

[0042] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the transmission plate assembly 3 has a first side surface 301, the first side surface 301 faces the limiting opening 102, the first side surface 301 abuts against the support assembly 1, and when the transmission plate assembly 3 moves relative to the support assembly 1, the coffee powder attached to the first side surface 301 can fall towards the powder discharge port 103. Through the abutment between the first side surface 301 of the transmission plate assembly 3 and the support assembly 1, the first side surface 301 of the transmission plate assembly 3 and the support assembly 1 undergo continuous relative movement when the transmission plate assembly 3 moves, and the resulting friction can scrape off the coffee powder attached to the first side surface 301, resulting in an automatic and efficient cleaning effect for the coffee powder.

[0043] like Figure 4-6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support assembly 1 includes a support member 11 and a cover plate 12; the powder conveying assembly 2 is disposed on the support member 11; the support member 11 is provided with the mounting cavity 101 and the limiting opening 102; the cover plate 12 is disposed on the support member 11 and the cover plate 12 is located on the side of the support member 11; the transmission plate assembly 3 is located between the support member 11 and the cover plate 12; the first side 301 of the transmission plate assembly 3 abuts against the support member 11; the transmission plate assembly 3 is provided with a second side 302 disposed opposite to the first side 301; the second side 302 abuts against the cover plate 12; when the transmission plate assembly 3 moves relative to the support assembly 1, the coffee powder attached to the second side 302 can fall toward the powder outlet 103. The first side 301 of the transmission plate assembly 3 abuts against the support member 11 and the second side 302 abuts against the cover plate 12. When the transmission plate assembly 3 moves, the first side 301 and the second side 302 rub against the support member 11 and the cover plate 12 respectively, which can simultaneously and efficiently scrape off coffee powder attached to both sides, making the cleaning range more comprehensive and cleaning without dead corners. This design can also prevent coffee powder from being attached to the second side 302 and clean it.

[0044] like Figure 9-11As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a rib 113 is formed on the support member 11, the rib 113 is located on the side of the limiting opening 102, the rib 113 abuts against the first side surface 301 of the transmission plate assembly 3, and a powder-passing gap is formed between the transmission plate assembly 3 and the support member 11, the powder-passing gap communicating with both the limiting opening 102 and the powder-dropping opening 103. The line contact between the rib 113 and the first side surface 301 of the transmission plate assembly 3 increases the local contact pressure, more effectively scraping off the attached coffee powder and improving the cleaning ability for residual coffee powder. Furthermore, the rib 113 creates a powder-passing gap between the transmission plate assembly 3 and the support member 11, allowing the coffee powder scraped off from the first side surface 301 to fall towards the powder-dropping opening 103.

[0045] like Figure 7-8 and Figure 10-11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support member 11 includes a support housing 111 and a powder outlet housing 112; the powder conveying assembly 2 is disposed on the support housing 111; the support housing 111 has the mounting cavity 101 and the limiting port 102; the powder outlet housing 112 is disposed on the support member 11 and is located on the side of the support housing 111; the powder outlet housing 112 has the powder drop port 103, or the powder outlet housing 112 and the support housing 111 enclose each other to form the powder drop port 103. The support housing 111 enables stable assembly of the transmission assembly, allowing the transmission plate assembly 3 to move stably to convey coffee powder. The powder outlet housing 112 allows coffee powder falling from the surface of the transmission plate assembly 3 to be output from the powder drop port 103, achieving the functions of powder conveying and powder cleaning.

[0046] like Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the powder dispensing housing 112 includes a powder dispensing part 1121 and a separating part 1122.

The powder dispensing part 1121, the separating part 1122, and the supporting housing 111 enclose the powder dropper 103. The powder dispensing part 1121 ensures that coffee powder scraped off the surface of the transmission plate assembly 3 can be output from the powder dropper 103, avoiding the accumulation of coffee powder on the surface of the transmission plate assembly 3, which would make subsequent cleaning and maintenance more troublesome. The separating part 1122 enhances the structural strength of the powder dispensing housing 112 and prevents deformation after being subjected to external forces.

[0047] like Figure 5 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the powder feeding assembly 2 includes a support member 21 and a powder feeding member 22. The support member 21 is disposed on the support assembly 1 and located at the limiting opening 102. The support member 21 abuts against the bottom wall of the limiting opening 102. The powder feeding member 22 is disposed on the support member 21. The powder feeding member 22 is located at the limiting opening 102 and abuts against the top wall of the limiting opening 102. The powder feeding member 22 is in transmission cooperation with the transmission plate assembly 3. The support member 21 and the powder feeding member 22 can move together relative to the support assembly 1 under the control of the transmission plate assembly 3. When the support member 21 and the powder feeding member 22 move relative to the support assembly 1, the coffee powder at the limiting opening 102 can fall toward the powder dropper 103. With the support member 21 abutting against the bottom wall of the limiting port 102 and the powder conveying member 22 abutting against the top wall of the limiting port 102, when the support member 21 and the powder conveying member 22 move synchronously under the drive of the transmission plate assembly 3, they can simultaneously scrape the top and bottom of the limiting port 102, thoroughly removing the coffee powder adhering to the inner wall of the limiting port 102, effectively preventing powder residue from remaining and accumulating in the limiting port 102, so that any residual coffee powder in the limiting port 102 can be dealt with in a timely manner.

[0048] like Figure 1 , Figure 6-7 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further includes a drive component 4, which is disposed on the support component 1 and is driveably connected to the transmission plate assembly 3.

By having the opposite sides of the brewing component 5 abut against the first limiting plane 1011 and the second limiting plane 1012, compared with the traditional stepped or arc-shaped abutment surfaces, this design can avoid or reduce steam leakage from the brewing component 5. Moreover, it can ensure the stable installation of the brewing component 5, enabling the brewing component 5 to operate stably.
