Description

Technical Field

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

[0002] In coffee machine applications, the brewing mechanism is typically used to hold and process coffee grounds. During the brewing process, coffee grounds easily adhere to the brewing mechanism. Under high humidity and high viscosity conditions, this can lead to clumping and residue of coffee grounds, affecting the flavor of subsequent brews. However, traditional coffee machines with brewing mechanisms do not suffer from the problems of a scraper mechanism, or the scraper mechanism's ineffective or clumpy scraping. Utility Model Content

[0003] Therefore, it is necessary to provide a coffee machine with a powder scraping structure to address the problems of traditional coffee machines having a brewing structure but lacking a powder scraping structure, or having a powder scraping structure that scrapes powder poorly or unevenly.

[0004] A powder scraping structure includes: a brewing component having an adjustment space and an opening, the opening communicating with the adjustment space, and an adapter hole; a power component disposed on the brewing component and located at the adapter hole, the power component being rotatable relative to the brewing component, the power component being rotatable relative to the brewing component by at least a first angle and a second angle; and a powder scraping component connected to the power component, the powder scraping component being disposed adjacent to the opening, wherein when the power component rotates by the first angle, the powder scraping component is located in a first position, and when the power component rotates by the second angle, the powder scraping component is located in a second position, the powder scraping component being used to scrape off powder adhering to the brewing component.

[0005] The first aspect of this application discloses a powder scraping structure. A power component drives a powder scraping component to rotate, moving it from a first position to a second position. For example, the first position could be one side of the opening, and the second position could be the other side of the opening. This ensures that the moving range of the powder scraping component covers the target area of ​​the brewing component during the scraping process, avoiding powder residue or incomplete scraping. By positioning the powder scraping component adjacent to the opening, it can scrape away powder concentrated at the opening in one go, improving its scraping efficiency. This design ensures precise execution of the scraping action, preventing interference with the normal brewing function of the coffee machine. With the power component located at the adapter hole and able to rotate stably there, the rotation of both the power component and the powder scraping structure is smoother, further improving the scraping efficiency. Moreover, the adapter hole effectively restricts the freedom of movement of the power component, improving its rotational stability and reliability.

[0006] In one embodiment, the adapter hole penetrates the brewing assembly. This penetration allows the power component to run from one end of the brewing assembly to the other, facilitating assembly and fixation and simplifying the overall structural layout. Furthermore, it makes disassembly and maintenance of the power component simpler and more convenient, simplifying inspection or replacement and reducing the difficulty of later maintenance.

[0007] In one embodiment, the opening is located at the end of the brewing assembly. By positioning the opening at the end of the brewing assembly, residual powder during the brewing process can be gathered at the end of the brewing assembly, reducing powder dispersion and allowing the powder scraper to more efficiently collect and clean the powder.

[0008] In one embodiment, the scraper assembly abuts against the end of the brewing assembly with the opening. By abutting the scraper assembly against the end of the brewing assembly with the opening, the adhering powder is completely scraped off, avoiding residue problems caused by gaps and improving the processing effect of coffee powder. This design effectively prevents residual coffee powder from affecting the flavor of subsequent brews and maintains effective scraping performance over a long period.

[0009] In one embodiment, a drive component is further included, which is drively connected to the power component and drives the power component to rotate relative to the brewing component. By directly controlling the rotation of the power component through the drive component, the starting, stopping, and angle switching of the powder-scraping action are ensured to be precisely executed, resulting in a high degree of automation. The drive component can be a protrusion, rib, or other protrusion, which abuts against the power component to drive its rotation. The drive component can also be driven by a power element such as a motor.

[0010] In one embodiment, the power assembly includes a rotating shaft, a transmission part, and a connecting part. The rotating shaft is disposed on the brewing assembly and located at the adapter hole. The rotating shaft is rotatable relative to the brewing assembly. The transmission part and the connecting part are both disposed on the rotating shaft and are located at opposite ends of the rotating shaft. The connecting part is connected to the powder scraping assembly. Power transmission through the transmission part drives the entire power assembly to rotate. For example, the transmission part rotates under the drive of the drive assembly, enabling smooth rotation of the power assembly. This design allows the powder scraping structure to rotate smoothly under the drive of the power assembly, resulting in smoother powder scraping, effectively improving scraping efficiency, and achieving better powder scraping results.

[0011] In one embodiment, the transmission unit includes a support portion and a transmission block. The support portion is disposed on the rotating shaft, and the transmission block is disposed on the support portion. Due to the arc-shaped transmission block, the entire powder-scraping structure is movable within the coffee machine. During movement, when the powder-scraping structure reaches a certain position, the transmission block can drive the entire transmission unit to rotate by resisting structural elements of the coffee machine, such as protrusions. This results in a simpler structure, lower cost, and a higher degree of automation.

[0012] In one embodiment, there are multiple transmission blocks, all of which are disposed on the support portion and spaced apart circumferentially along the support portion. The multiple transmission blocks allow the entire transmission unit to rotate, resulting in a simple structure and a high degree of automation. Preferably, there are two transmission blocks.

[0013] In one embodiment, the rotating shaft, the transmission part, and the connecting part are integrated into one unit. This integrated design eliminates the assembly steps required for separate structures, reducing the complexity of parts processing and installation. Furthermore, the integrated structure has no weak connection points, making it less prone to wear or breakage during long-term use, thus extending the service life of the powder scraping structure.

[0014] In one embodiment, the powder scraping assembly includes a support structure and a scraper structure. The support structure is connected to the power assembly and can rotate under the drive of the power assembly. The scraper structure is disposed on the support structure and is adjacent to the opening. The support structure connects the power assembly and the scraper structure, ensuring that the rotation of the power assembly is stably transmitted to the scraper structure, guaranteeing stable and smooth rotation of the scraper structure. The adjacent arrangement of the scraper structure to the opening allows it to thoroughly scrape away powder adhering to the brewing assembly as it moves from a first position to a second position. This design enables the scraper structure to precisely cover the target area during the powder scraping process, avoiding powder residue.

[0015] In one embodiment, the support structure includes a rotating part and a supporting part. The rotating part is connected to the power assembly, and the supporting part is disposed on the rotating part. The scraper structure is disposed on the supporting part. The supporting part provides stable support and power transmission to the scraper structure. The scraper structure, rotating part, and supporting part rotate together to achieve the function of scraping away dust.

[0016] In one embodiment, the support structure is provided with mounting holes that can mate with the power component. This mounting hole ensures that the powder scraping component rotates together with the power component, preventing the powder scraping action from failing due to loosening of the powder scraping component, and achieving a stable and smooth powder scraping effect. Furthermore, it simplifies the installation steps of the support structure and the power component, improves assembly efficiency, and reduces manual debugging costs.

[0017] In one embodiment, the scraper structure is arc-shaped. This arc shape allows for a better match between the scraper structure and the opening edge, ensuring close contact between the scraper and the surface of the brewing component, reducing powder residue. This design results in better appearance quality. Furthermore, the arc shape provides wider coverage, avoiding areas that might be missed by a straight scraper.

[0018] In one embodiment, the brewing assembly includes a brewing shell and a pusher assembly. The brewing shell has the adapter hole, the adjustment space, and the opening. The pusher assembly is disposed on the brewing shell and located in the adjustment space. The brewing shell is movable relative to the pusher assembly. By allowing the brewing shell to move relative to the pusher assembly, the depth of the space for dispensing powder can be adjusted to meet different usage needs.

[0019] In one embodiment, the brewing housing has at least a third position when it moves, and when the brewing housing is in the third position, the power component can drive the powder scraping component to scrape off the powder adhering to the brewing housing. By moving the brewing housing to the third position, for example, when the depth of the space used for dispensing powder is zero or close to zero, the power component drives the powder scraping component to scrape off the powder from the brewing housing, which can more effectively handle residual powder, resulting in higher efficiency and better effect in handling residual powder.

[0020] In one embodiment, the brewing housing includes a support base and a brewing shell, the support base having the adapter hole, the brewing shell being disposed on the support base, and the brewing shell having the adjustment space and the opening.

[0021] In one embodiment, a limiting portion is formed on the pusher assembly. The brewing housing has at least a third position and a fourth position during movement. When the brewing housing is in the third position, it abuts against the limiting portion, and one end of the pusher assembly is located at the opening. When the brewing housing is in the fourth position, it separates from the limiting portion. By having one end of the pusher assembly located at the opening when the brewing housing is in the third position, the power component only drives the powder scraping component to scrape the powder from the brewing housing when the depth of the space for dispensing powder is zero or close to zero. This allows for more effective processing of residual powder, resulting in higher efficiency and better results. The limiting portion improves the reliability of the movement of the brewing housing relative to the pusher assembly, effectively preventing overtravel.

[0022] A coffee machine comprising: the aforementioned powder scraping structure.

[0023] The second aspect of this application discloses a coffee machine in which a scraper structure driven by a power component can scrape off residual coffee powder on the brewing component, preventing the accumulation of residual coffee powder from affecting the flavor of subsequent coffee. Furthermore, the scraping action of the scraper structure is smooth and stable. By arranging the scraper component adjacent to the opening, the scraper component can remove powder concentrated at the opening in one go, improving the scraping efficiency of the scraper component.

[0042] 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.

[0043] 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.

[0044] Example 1

[0045] like Figure 1-6As shown, this embodiment discloses a powder scraping structure, including: a brewing component 1, which has an adjustment space 101 and an opening 102, the opening 102 communicating with the adjustment space 101, and an adapter hole 103; a power component 2, which is disposed on the brewing component 1 and located at the adapter hole 103, the power component 2 being rotatable relative to the brewing component 1, and the power component 2 being rotatable relative to the brewing component 1 by at least a first angle and a second angle; and a powder scraping component 3, which is connected to the power component 2 and is disposed adjacent to the opening 102, wherein when the power component 2 rotates by the first angle, the powder scraping component 3 is located in a first position, and when the power component 2 rotates by the second angle, the powder scraping component 3 is located in a second position, and the powder scraping component 3 is used to scrape off the powder adhering to the brewing component 1.

[0046] The first aspect of this application discloses a powder scraping structure. A power component 2 drives a powder scraping component 3 to rotate, moving the component from a first position to a second position. For example, the first position could be one side of the opening 102, and the second position could be the other side of the opening 102. This ensures that the range of motion of the powder scraping component 3 covers the target area of ​​the brewing component 1 during the scraping process, avoiding powder residue or incomplete scraping. By aligning the powder scraping component 3 adjacent to the opening 102, the component can scrape away powder concentrated at the opening 102 in one go, improving its scraping efficiency. This design ensures precise execution of the scraping action, preventing interference with the normal brewing function of the coffee machine. With the power component 2 located at the adapter hole 103 and able to rotate stably at this location, the rotation of both the power component 2 and the powder scraping structure is smoother, further improving the scraping efficiency of the component. Furthermore, the adapter hole 103 effectively restricts the degree of freedom of movement of the power component 2, improving the stability and reliability of its rotation.

[0047] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the adapter hole 103 penetrates through the brewing assembly 1. By allowing the adapter hole 103 to penetrate through the brewing assembly 1, the power assembly 2 can pass through from one end of the brewing assembly 1 to the other, facilitating assembly and fixation and simplifying the overall structural layout. Furthermore, the disassembly and maintenance of the power assembly 2 are simpler and more convenient, making inspection or replacement of the power assembly 2 easier and reducing the difficulty of later maintenance.

[0048] like Figure 1 , Figure 4-5 and Figure 14As shown, in addition to the features of the above embodiments, this embodiment further specifies that the opening 102 is located at the end of the brewing component 1. By positioning the opening 102 at the end of the brewing component 1, residual powder during the brewing process can be easily gathered at the end of the brewing component 1, reducing powder dispersion and allowing the powder scraper component 3 to more efficiently collect and clean the powder.

[0049] like Figure 1 , Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the scraper assembly 3 abuts against the end of the brewing assembly 1 with the opening 102. By abutting the scraper assembly 3 against the end of the brewing assembly 1 with the opening 102, the attached powder is completely scraped off, avoiding residue problems caused by gaps and improving the processing effect on coffee powder. This design effectively prevents residual coffee powder from affecting the flavor of subsequent brews and maintains long-term effective scraping performance.

[0050] In addition to the features of the above embodiments, this embodiment further specifies that it includes a drive component, which is connected to the power component 2 in a transmission manner. The drive component is used to drive the power component 2 to rotate relative to the brewing component 1. By directly controlling the rotation of the power component 2 through the drive component, the starting, stopping, and angle switching of the powder scraping action are ensured to be precisely executed, resulting in a high degree of automation. The drive component can be a protrusion, rib, or other protrusion, which abuts against the power component 2 to drive its rotation. The drive component can also be driven by a power element such as a motor.

[0051] like Figure 7-10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the power assembly 2 includes a rotating shaft 21, a transmission part 22, and a connecting part 23. The rotating shaft 21 is disposed on the brewing assembly 1 and located at the adapter hole 103. The rotating shaft 21 is rotatable relative to the brewing assembly 1. The transmission part 22 and the connecting part 23 are both disposed on the rotating shaft 21 and are respectively located at both ends of the rotating shaft 21. The connecting part 23 is connected to the powder scraping assembly 3. The power transmission through the transmission part 22 can drive the entire power assembly 2 to rotate. For example, the transmission part 22 can rotate under the drive of the drive assembly, which can realize the smooth rotation of the power assembly 2. This design allows the powder scraping structure to rotate smoothly under the drive of the power assembly 2, making powder scraping smoother, effectively improving powder scraping efficiency, and achieving better powder scraping effect.

[0052] like Figure 11As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the transmission part 22 includes a support part 221 and a transmission block 222, the support part 221 is disposed on the rotating shaft 21, and the transmission block 222 is disposed on the support part 221. Due to the arrangement of the transmission block 222, which is arc-shaped, the entire powder scraping structure is movable within the coffee machine. During the movement of the powder scraping structure, when it reaches a certain position, the transmission block 222 can drive the entire transmission part 22 to rotate under the resistance of structural elements of the coffee machine, such as protrusions. This results in a simpler structure, lower cost, and a higher degree of automation.

[0053] like Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of transmission blocks 222 is multiple, and all multiple transmission blocks 222 are disposed on the support portion 221, and the multiple transmission blocks 222 are arranged at intervals along the circumference of the support portion 221. The arrangement of multiple transmission blocks 222 can drive the entire transmission portion 22 to rotate, resulting in a simple structure and a high degree of automation. Preferably, the number of transmission blocks 222 is two.

[0054] like Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the rotating shaft 21, the transmission part 22, and the connecting part 23 are integrally formed. By integrating the rotating shaft 21, the transmission part 22, and the connecting part 23, the assembly steps of the separate structures are eliminated, reducing the complexity of parts processing and installation. Furthermore, the integral structure has no weak connection points, making it less prone to wear or breakage during long-term use, thus extending the service life of the powder scraping structure.

[0055] like Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the powder scraping component 3 includes a support structure 31 and a scraper structure 32. The support structure 31 is connected to the power component 2 and can rotate under the drive of the power component 2. The scraper structure 32 is disposed on the support structure 31 and is adjacent to the opening 102. The support structure 31 connects the power component 2 and the scraper structure 32, ensuring that the rotation of the power component 2 is stably transmitted to the scraper structure 32, thus guaranteeing the stable and smooth rotation of the scraper structure 32. Because the scraper structure 32 is adjacent to the opening 102, it thoroughly scrapes off the powder adhering to the brewing component 1 during the process of moving from the first position to the second position. This design allows the scraper structure 32 to precisely cover the target area during the powder scraping process, avoiding powder residue.

[0056] like Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support structure 31 includes a rotating part 311 and a supporting part 312. The rotating part 311 is connected to the power assembly 2, the supporting part 312 is disposed on the rotating part 311, and the scraper structure 32 is disposed on the supporting part 312. The supporting part 312 provides stable support and power transmission to the scraper structure 32. The scraper structure 32, the rotating part 311, and the supporting part 312 rotate together to achieve the function of scraping away dust.

[0057] like Figure 9 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support structure 31 is provided with an assembly hole 301, which can cooperate with the power component 2. The assembly hole 301 allows cooperation with the power component 2, ensuring that the powder scraping component 3 rotates together with the power component 2, preventing the powder scraping action from failing due to loosening of the powder scraping component 3, and achieving a stable and smooth powder scraping effect. Furthermore, it simplifies the installation steps of the support structure 31 and the power component 2, improves assembly efficiency, and reduces manual debugging costs.

[0058] like Figure 7-9 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the scraper structure 32 is arc-shaped. By making the scraper structure 32 arc-shaped, this structure better matches the edge of the opening 102, ensuring close contact between the scraper and the surface of the brewing component 1, reducing powder residue. This design results in better appearance quality. Furthermore, the arc-shaped structure covers a wider area, avoiding areas that might be missed by a straight scraper.

[0059] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the brewing assembly 1 includes a brewing shell 11 and a pusher assembly 12. The brewing shell 11 is provided with the adapter hole 103, the brewing shell 11 is provided with the adjustment space 101 and the opening 102, and the pusher assembly 12 is disposed on the brewing shell 11 and located at the adjustment space 101. The brewing shell 11 is movable relative to the pusher assembly 12. By allowing the brewing shell 11 to move relative to the pusher assembly 12, the depth of the space used for dispensing powder can be adjusted to adapt to different usage needs.

[0060] like Figure 1-3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the brewing housing 11 has at least a third position when it moves; when the brewing housing 11 is in the third position, the power component 2 can drive the powder scraping component 3 to scrape off the powder attached to the brewing component 1. By moving the brewing housing 11 to the third position, for example, when the depth of the space used for dispensing powder is zero or close to zero, the power component 2 drives the powder scraping component 3 to scrape the powder from the brewing housing 11, which can more effectively handle residual powder, resulting in higher efficiency and better effect in handling residual powder.

[0061] like Figure 14 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the brewing shell 11 includes a support base 111 and a brewing shell 112, the support base 111 is provided with the adapter hole 103, the brewing shell 11 is disposed on the support base 111, and the brewing shell 11 is provided with the adjustment space 101 and the opening 102.

[0062] like Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a limiting part 121 is formed on the pusher assembly 12; the brewing shell 11 has at least a third position and a fourth position when it moves; when the brewing shell 11 is in the third position, the brewing shell 11 abuts against the limiting part 121 and one end of the pusher assembly 12 is located at the opening 102; when the brewing shell 11 is in the fourth position, the brewing shell 11 is separated from the limiting part 121. By having one end of the pusher assembly 12 located at the opening 102 when the brewing shell 11 is in the third position, the power assembly 2 only drives the powder scraping assembly 3 to scrape the powder from the brewing shell 11 when the depth of the space for dispensing powder is zero or close to zero. This allows for more effective processing of residual powder, resulting in higher efficiency and better effect in handling residual powder. The setting of the limiting part 121 improves the reliability of the movement of the brewing shell 11 relative to the pusher assembly 12, effectively preventing overtravel.

Furthermore, the scraping action of the scraper structure is smooth and stable. By arranging the scraper component 3 adjacent to the opening 102, the scraper component 3 can scrape off the powder concentrated at the opening 102 in one go, improving the scraping efficiency of the scraper component 3.

[0066] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent.
