[0033] In existing coffee machines, some powder scraping assemblies use elastic powder scraping members to scrape powder. The elastic powder scraping members may interfere with the moving powder receiving barrel, thereby affecting the operation of the powder receiving barrel.

[0034] Based on the above reasons, the embodiment of the present application provides a coffee machine powder scraping structure, which includes a powder scraping limiting assembly and a powder scraping assembly.

[0035] In some scenarios, a coffee machine powder scraping structure according to an embodiment of the present application can be applied to a coffee machine to improve the use effect of the coffee machine.

[0036] A coffee machine powder scraping structure provided in an embodiment of the present application is described in detail below with reference to specific examples.

[0037] Figure 1 A three-dimensional exploded schematic diagram of a coffee machine powder scraping structure provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the powder scraping structure of the coffee machine includes a powder scraping limiting assembly 6 and a powder scraping assembly 7. The powder scraping assembly 7 includes a powder scraping plate box 71, a powder scraping plate torsion spring 72, a powder scraping plate fixing piece 73 and a powder scraping plate 74. The powder scraping plate box 71 is arranged on the frame 1, the powder scraping plate fixing piece 73 is rotatably connected to the powder scraping plate box 71, the powder scraping plate torsion spring 72 is arranged in the powder scraping plate box 71, the powder scraping plate torsion spring 72 is used to drive the powder scraping plate fixing piece 73 to reset, the rotating shaft of the powder scraping plate 74 is inserted on the powder scraping plate fixing piece 73, and the powder scraping limiting assembly 6 is used to limit the powder scraping plate 74 or make way for the powder scraping plate 74.

[0038] like Figure 1As shown, structurally, the powder scraping assembly 7 includes a powder scraping plate box 71, a powder scraping plate torsion spring 72, a powder scraping plate fixing member 73 and a powder scraping plate 74. The powder scraping plate box 71 is arranged on the frame 1, and the powder scraping plate box 71 is used to fix the powder scraping assembly 7.

[0039] Structurally, the scraper plate fixing member 73 is used to install the scraper plate 74 , and the scraper plate fixing member 73 is rotatably connected to the scraper plate box 71 , so that after the scraper plate fixing member 73 installs the scraper plate 74 , the scraper plate 74 can rotate together with the scraper plate fixing member 73 .

[0040] like Figure 1 As shown, the scraper plate torsion spring 72 is arranged in the scraper plate box 71, and the scraper plate torsion spring 72 is used to drive the scraper plate fixing part 73 to reset, so that after the scraper plate 74 rotates together with the scraper plate fixing part 73, the scraper plate torsion spring 72 can drive the scraper plate fixing part 73 and the scraper plate 74 to reset together.

[0041] like Figure 1 As shown, the rotating shaft of the scraper plate 74 is inserted into the scraper plate fixing member 73, so as to facilitate the installation of the scraper plate 74.

[0042] Exemplarily, the rotating shaft of the scraper plate 74 can be detachably inserted into the scraper plate fixing member 73 to facilitate cleaning of the scraper plate 74 .

[0043] Exemplarily, the powder scraper plate 74 may be provided with a structure for scraping off coffee powder or coffee grounds.

[0044] Figure 2 This is a three-dimensional schematic diagram of a coffee machine powder scraping structure provided in an embodiment of the present application. Figure 3 for Figure 2 A partial structural diagram of a coffee machine powder scraping structure at point A, when working, the powder scraping limiting component 6 is used to limit the powder scraping plate 74, and the powder scraping limiting component 6 can limit the powder scraping plate 74 in the rotation direction of the powder scraping plate 74.

[0045] During operation, the powder scraping limiting assembly 6 can also make way for the powder scraping plate 74, so that the powder scraping plate 74 can rotate to scrape the coffee powder or remove the coffee grounds on the powder receiving structure of the coffee machine.

[0046] Figure 7 This is a schematic diagram of the structure of a coffee machine powder scraping structure in a first state provided by an embodiment of the present application, as shown in FIG. Figure 7 As shown, the powder scraping limiting assembly 6 limits the powder scraping plate 74 on the first side of the powder scraping limiting assembly 6, and the powder scraping plate 74 is located before scraping the powder of the extraction tube bracket assembly 3, and the extraction tube bracket assembly 3 is a structural component for extracting coffee.

[0047] Figure 8This is a schematic diagram of the structure of a coffee machine powder scraping structure in a second state provided by an embodiment of the present application, as shown in FIG. Figure 8 As shown, the powder scraping structure of the coffee machine is in a state where the powder scraping plate 74 is crossing the powder scraping limit assembly 6. The powder scraping plate 74 is ready to scrape the coffee powder of the extraction cylinder bracket assembly 3. The powder scraping plate 74 can also scrape the coffee grounds cake on the extraction cylinder bracket assembly 3.

[0048] Fig. 9 This is a schematic diagram of the structure of a coffee machine powder scraping structure in a third state provided by an embodiment of the present application, such as Fig. 9 As shown, the powder scraping plate 74 in the powder scraping structure of the coffee machine has passed the powder scraping limit assembly 6. When scraping powder, the powder scraping plate 74 has completed scraping the coffee powder of the extraction cartridge support assembly 3; when scraping the coffee residue cake, the powder scraping plate 74 has completed scraping the coffee residue cake on the extraction cartridge support assembly 3.

[0049] The beneficial effect brought about by the above-mentioned implementation method is that the powder scraping plate is limited by the powder scraping limiting assembly, so that the powder scraping plate will not interfere with the powder receiving barrel of the coffee machine under the limiting effect, will not affect the normal operation of the powder receiving barrel of the coffee machine, and improves the use effect of the coffee machine.

[0050] In some implementations, the powder scraping limit assembly 6 includes a limit shell 61, a rotating plate 62, a latch 63 and a latch spring 64. The limit shell 61 is disposed on the frame 1, the rotating plate 62 is rotatably connected to the limit shell 61, and the latch 63 can move axially in the limit shell 61.

[0051] like Figure 1 As shown, the powder scraping limiting assembly 6 includes a limiting shell 61 , a rotating plate 62 , a latch 63 and a latch spring 64 . The limiting shell 61 is disposed on the frame 1 , and is used to fix the powder scraping limiting assembly 6 .

[0052] like Figure 1 As shown, the rotating plate 62 is rotatably connected to the limiting housing 61 , so that the rotating plate 62 can rotate on the limiting housing 61 .

[0053] like Figure 1 As shown, the latch 63 can move axially in the limiting housing 61 . When the latch 63 moves axially in the limiting housing 61 , the latch 63 can limit the scraping plate 74 or make way for the scraping plate 74 .

[0054] In some implementations, when the rotating plate 62 rotates along the first rotation direction to push the detent pin 63 to compress the detent pin spring 64, the detent pin 63 is pushed into the limiting shell 61 to make way for the scraper plate 74. After the scraper plate 74 passes over the detent pin 63, the detent pin spring 64 supports the detent pin 63 to return to its original position to limit the scraper plate 74.

[0055] like Figure 1 As shown, when the rotating plate 62 rotates along the first rotating direction to push the latch 63 to compress the latch spring 64 , the latch 63 is pushed to move into the limiting shell 61 to make way for the scraper plate 74 , so that the rotating plate 62 can control the latch 63 to make way for the scraper plate 74 .

[0056] like Figure 1 As shown, after the powder scraping plate 74 passes over the latch 63 , the latch spring 64 pushes the latch 63 to return to the position limiting the powder scraping plate 74 , so that the latch 63 can automatically restore the position limiting the powder scraping plate 74 .

[0057] The beneficial effect brought about by the above-mentioned implementation method is that when the rotating plate rotates, it can push the pin to make way for the scraper plate, so that the rotating plate can control the pin to make way for the scraper plate; the pin can automatically restore the limit position of the scraper plate; it is easy to control the process of making way and limiting the scraper plate.

[0058] In some implementations, the rotating plate 62 is provided with a first inclined surface 621 , the latch 63 is provided with a second inclined surface 631 that cooperates with the first inclined surface 621 , and the latch spring 64 pushes the latch 63 and the rotating plate 62 to abut against each other.

[0059] Figure 4 This is a schematic diagram of a three-dimensional exploded structure of a coffee machine powder scraping structure provided in an embodiment of the present application. Figure 5 A schematic diagram of a three-dimensional structure of a rotating plate provided in an embodiment of the present application, such as Figure 4 and Figure 5 As shown, structurally, the rotating plate 62 is provided with a first inclined surface 621 , and the latch 63 is provided with a second inclined surface 631 that cooperates with the first inclined surface 621 . The first inclined surface 621 and the second inclined surface 631 are used to transmit pressure to each other.

[0060] Structurally, the bayonet spring 64 pushes the bayonet 63 and the rotating plate 62 to abut against each other, so that the first inclined surface 621 and the second inclined surface 631 can abut against each other and transmit pressure to each other, thereby pushing the bayonet 63 .

[0061] In some implementations, when the rotating plate 62 rotates along the first rotation direction, the first inclined surface 621 of the rotating plate 62 squeezes the second inclined surface 631 of the latch 63 to push the latch 63, and the latch 63 compresses the latch spring 64 and moves into the limiting shell 61 to make way for the scraper plate 74. After the scraper plate 74 passes over the latch 63, the latch spring 64 supports the latch 63 to reset and limit the scraper plate 74.

[0062] like Figure 1As shown, structurally, when the rotating plate 62 rotates along the first rotating direction, the first inclined surface 621 of the rotating plate 62 squeezes the second inclined surface 631 of the pin 63, so that the rotating plate 62 can squeeze the pin 63 through the first inclined surface 621. The pin 63 is pushed after being squeezed, and then the pin 63 compresses the pin spring 64 and moves into the limit shell 61. After entering the limit shell 61, the pin 63 can make way for the scraper plate 74.

[0063] After the powder scraper plate 74 passes over the latch pin 63 , the latch pin spring 64 supports the latch pin 63 to achieve the reset of the latch pin 63 . After the reset, the latch pin 63 limits the powder scraper plate 74 .

[0064] The beneficial effect brought about by the above implementation method is that the first inclined surface and the second inclined surface interact to push the latch, so that the latch can be easily pushed to make way for the powder scraping plate, thereby improving the structural compactness of the powder scraping structure of the coffee machine.

[0065] In some implementations, after the scraper plate 74 passes over the latch 63 and the latch spring 64 supports the latch 63 to reset, the second inclined surface 631 of the latch 63 presses the first inclined surface 621 of the rotating plate 62, so that the rotating plate 62 rotates in the opposite direction of the first rotation direction to reset.

[0066] like Figure 1 As shown, structurally, after the powder scraper plate 74 passes over the latch 63 and the latch spring 64 pushes the latch 63 to reset, the latch 63 can reversely squeeze the rotating plate 62, and the second inclined surface 631 of the latch 63 squeezes the first inclined surface 621 of the rotating plate 62, so that the rotating plate 62 rotates and resets in the opposite direction of the first rotation direction, thereby realizing the reset of the rotating plate 62. After the rotating plate 62 is reset, it can continue to play a limiting role on the powder scraper plate 74 in the next coffee extraction cycle.

[0067] The beneficial effect brought about by the above implementation method is that it is easy to realize the resetting of the rotating plate. After the rotating plate is reset, it can continue to play a limiting role on the scraper plate in the next coffee extraction cycle.

[0068] In some implementations, the latch 63 passes through the rotation axis of the rotating plate 62 and is rotatably connected in the limiting housing 61 . The first inclined surface 621 is located on the rotation axis of the rotating plate 62 , and the second inclined surface 631 is provided on the rotation axis of the latch 63 .

[0069] like Figures 1 to 4 As shown, structurally, the latch 63 passes through the rotating shaft of the rotating plate 62 and is rotatably connected in the limiting housing 61, so that the latch 63 and the rotating shaft of the rotating plate 62 can rotate coaxially, thereby improving the concentricity of the latch 63 and the rotating shaft of the rotating plate 62 when rotating.

[0070] like Figures 1 to 4As shown, the first inclined surface 621 is located on the rotating shaft of the rotating plate 62, and the second inclined surface 631 is arranged on the rotating shaft of the latch 63, so that when the rotating shaft of the latch 63 and the rotating plate 62 rotate coaxially, the first inclined surface 621 and the second inclined surface 631 interact with each other, thereby ensuring the stability of the latch 63 and the rotating plate 62 when they interact with each other.

[0071] The beneficial effect brought about by the above implementation method is that the rotating shaft of the bayonet and the rotating plate can rotate coaxially, thereby improving the concentricity of the rotating shaft of the bayonet and the rotating plate during rotation.

[0072] The beneficial effect brought by the above implementation method is that when the latch and the rotating shaft of the rotating plate rotate coaxially, the first inclined surface and the second inclined surface on the latch and the rotating shaft of the rotating plate interact with each other, thereby improving the stability of the interaction between the latch and the rotating plate.

[0073] In some implementations, a scraper plate slope 741 is provided on one side of the scraper plate 74 near the pin 63. When the scraper plate 74 squeezes the pin 63 through the scraper plate slope 741, the pin 63 compresses the pin spring 64 and moves into the limiting shell 61 to make way for the scraper plate 74. After the scraper plate 74 passes over the pin 63, the pin spring 64 supports the pin 63 to reset and limit the scraper plate 74.

[0074] Figure 6 A schematic diagram of a top view of a coffee machine powder scraping structure provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, a scraper plate inclined surface 741 is provided on one side of the scraper plate 74 close to the latch 63, and the scraper plate inclined surface 741 can squeeze the latch 63 in the lateral direction of the scraper plate 74, so that the scraper plate 74 can squeeze the latch 63 through the scraper plate inclined surface 741 when rotating.

[0075] like Figure 6 As shown, when the scraper plate 74 rotates, the scraper plate 74 presses the latch 63 through the scraper plate inclined surface 741, and the latch 63 compresses the latch spring 64 and moves into the limiting housing 61 to make way for the scraper plate 74, so that the scraper plate 74 can rotate in the opposite direction and pass over the latch 63.

[0076] When in use, after the scraper plate 74 squeezes the latch 63 through the scraper plate inclined surface 741 , the scraper plate 74 passes over the latch 63 and the latch spring 64 pushes the latch 63 to reset the scraper plate 74 so that the latch 63 resumes the limiting function of the scraper plate 74 .

[0077] The beneficial effect brought about by the above implementation method is that when the scraper plate rotates, the inclined surface of the scraper plate can press the latch, so that the scraper plate can reversely pass over the latch, thereby improving the use effect of the scraper structure of the coffee machine.

[0078] In some implementations, the scraper plate fixing member 73 is provided with an insertion hole 731, and the inner side wall of the insertion hole 731 is provided with an insertion hole recess 731a, and the rotating shaft of the scraper plate 74 is provided with a scraper plate buckle 742, and the scraper plate buckle 742 is provided with a buckle protrusion 742a, a buckle recess 742b and a buckle button 742c in sequence, and the buckle recess 742b is lower than the buckle protrusion 742a. ​​When the rotating shaft of the scraper plate 74 is inserted into the insertion hole 731, the buckle protrusion 742a is locked into the insertion hole recess 731a.

[0079] Fig.10 A schematic diagram of a three-dimensional exploded structure of a powder scraper and a powder scraper fixing member provided in an embodiment of the present application, such as Fig.10 As shown, the scraper plate fixing member 73 is provided with an insertion hole 731 , and the insertion hole 731 is used to fix the scraper plate 74 .

[0080] Structurally, the rotating shaft of the powder scraper plate 74 can be detachably connected to the insertion hole 731, so that the powder scraper plate 74 is easy to disassemble and wash.

[0081] Structurally, an insertion hole recess 731 a is provided on the inner side wall of the insertion hole 731 , and the insertion hole recess 731 a is convenient for fixing the rotating shaft of the scraper plate 74 .

[0082] like Fig.10 As shown, a scraper plate buckle 742 is provided on the rotating shaft of the scraper plate 74 , and the scraper plate buckle 742 is used for detachably connecting the rotating shaft of the scraper plate 74 and the plug hole 731 .

[0083] like Fig.10 As shown, the scraper plate buckle 742 is provided with a buckle protrusion 742a, a buckle recess 742b and a buckle button 742c in sequence. The scraper plate buckle 742 can be depressed into the shaft of the scraper plate 74 by pressing. The buckle button 742c is used for the user to press. The buckle protrusion 742a is used to buckle into the recess 731a of the socket to fix the scraper plate buckle 742. When the shaft of the scraper plate 74 is inserted into the socket 731, the buckle protrusion 742a is snapped into the recess 731a of the socket.

[0088] like Fig.10 As shown, the scraper plate 74 is provided with a coffee powder hole 743 for passing coffee powder, so that the coffee powder hole 743 is convenient for loading coffee powder after passing through the scraper plate 74. Fig. 9 As shown, it is convenient to load coffee powder into the extraction structure of the coffee machine through the coffee powder hole 743 on the scraper plate 74, so as to facilitate the subsequent coffee making.

[0089] The beneficial effect brought about by the above implementation method is that it is convenient to load coffee powder into the coffee machine through the coffee powder holes on the powder scraper plate, which is convenient for subsequent coffee making.

[0090] In some implementations, a retaining ring 743a is provided on the circumference of the coffee powder hole 743 for enclosing the coffee powder.

[0091] like Fig. 9 As shown, a retaining ring 743a for enclosing coffee powder is provided on the circumference of the coffee powder hole 743. The retaining ring 743a is used to enclose the coffee powder to facilitate loading the coffee powder into the coffee machine.

[0092] The beneficial effect brought about by the above implementation method is that it is easy to load coffee powder into the coffee machine, thereby improving the use effect of the coffee machine.

[0093] The embodiment of the present application also provides a coffee machine, comprising the coffee machine powder scraping structure as described above. The coffee machine limits the powder scraping plate by the powder scraping limiting assembly, so that the powder scraping plate will not interfere with the powder receiving barrel of the coffee machine under the limiting effect, and will not affect the normal operation of the powder receiving barrel of the coffee machine, thereby improving the use effect of the coffee machine.

[0094] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
