[0039] Combination Figure 1-7 As shown, in some embodiments, the powder bowl cleaner includes: a housing 100, a cleaning fan blade 200, and a magnetic rotating component 300. The housing 100 has an inner accommodating groove 110; the cleaning fan blade 200 is movably disposed within the accommodating groove 110, and a magnetic suction portion 210 is provided at the bottom of the cleaning fan blade 200; the magnetic rotating component 300 is disposed outside the accommodating groove 110 and directly below the magnetic suction portion 210; wherein, when the magnetic rotating component 300 rotates, the magnetic suction portion 210 can rotate with the magnetic rotating component 300 under the action of magnetic attraction, thereby driving the cleaning fan blade 200 to rotate.

[0040] The powder bowl cleaner provided in this embodiment cleans the powder bowl by using a cleaning fan blade 200, and the powder removed from the powder bowl falls into the receiving groove 110. Since the bottom of the cleaning fan blade 200 is provided with a magnetic suction part 210, and the outside of the receiving groove 110 is provided with a magnetic rotating member 300, the cleaning fan blade 200 can be rotated to clean the powder bowl under the magnetic attraction between the magnetic rotating member 300 and the magnetic suction part 210. The magnetic drive method maintains the integrity of the lower side wall of the receiving groove 110, and the powder inside the receiving groove 110 is easy to clean, improving the cleaning efficiency of the powder that falls into the powder bowl cleaner and extending the service life of the powder bowl cleaner.

[0041] Optionally, the upper side wall of the housing 100 has an opening that communicates with the receiving cavity. In this way, the powder bowl is placed upside down on the outside of the cleaning fan blade 200 inside the receiving cavity, and the inside of the powder bowl is cleaned by the rotation of the cleaning fan blade 200.

[0042] Optionally, the magnetic rotating component 300 is disposed on the lower side wall of the housing 100. This arrangement allows the magnetic rotating component 300 to be concealed, reducing the lateral width of the powder bowl cleaner and facilitating its installation.

[0043] Optionally, the cleaning fan blade 200 includes a support base 201 and blades 202. The support base 201 is movably disposed within the receiving groove 110, and a magnetic suction part 210 is disposed at the bottom of the support base 201. Multiple blades 202 are provided, and the multiple blades 202 are evenly disposed on the outer side of the support base 201 and connected to the outer wall of the support base 201. In this way, the cleaning fan blade 200 is divided into the support base 201 and the blades 202. The support base 201 provides stable support, improving the stability of the cleaning fan blade 200 during rotation. The multiple blades 202 evenly disposed on the outer side of the support base 201 improve the cleaning effect on the powder container.

[0044] Specifically, there are three blades 202, which are evenly arranged on the outside of the support base 201.

[0045] Optionally, the support base 201 has a cylindrical structure, with a support shaft at the center of the upper side wall. The lower end of the blade 202 is connected to the outer peripheral wall of the support base 201, and the upper end of the blade 202 is connected to the outer peripheral wall of the support shaft. In this way, the cylindrical support base 201 can provide stable support. When the magnetic suction part 210 is driven by the magnetic rotating part 300, the support base 201 can be stably driven to rotate by the magnetic suction part 210, thereby performing stable cleaning of the powder bowl.

[0046] Optionally, the magnetic attraction part 210 is a disc-shaped magnet embedded in the bottom of the support base 201, and the axis of the magnetic attraction part 210 coincides with the axis of the support base 201. In this way, when the magnetic attraction part 210 is driven by the magnetic rotating member 300, the magnetic attraction part 210 can drive the support base 201 to rotate more stably, the force on the support base 201 is more uniform, and the rotational stability of the support base 201 is higher.

[0047] Optionally, the lower inner wall of the receiving groove 110 is provided with a limiting post 120, and the lower inner wall of the cleaning fan blade 200 is provided with a limiting groove 220, with the limiting post 120 movably embedded in the limiting groove 220. In this way, the cooperation between the limiting post 120 and the limiting groove 220 can guide the rotation of the cleaning fan blade 200, improve the rotational stability of the cleaning fan blade 200, and reduce the risk of the cleaning fan blade 200 deviating.

[0048] Optionally, the limiting groove 220 is formed at the center of the lower side wall of the support 201. In this way, the support 201 can rotate around its center by the cooperation of the limiting post 120 and the limiting groove 220, which further improves the rotational stability of the support 201.

[0049] Optionally, the height of the limiting post 120 is greater than the depth of the limiting groove 220. In this way, the limiting post 120 provides support for the support base 201, creating a gap between the lower side wall of the support base 201 and the lower interior of the receiving groove 110, reducing the frictional resistance between the support base 201 and the receiving groove 110, and allowing the support base 201 to be driven more effectively.

[0050] Optionally, a groove 130 is provided on the lower side wall of the housing 100, and the magnetic rotating component 300 is movably embedded in the groove 130. In this way, the groove 130 can limit the rotation of the magnetic rotating component 300, preventing it from shifting and ensuring that the magnetic rotating component 300 is always directly below the magnetic suction part 210. When the magnetic rotating component 300 rotates, it more stably drives the magnetic suction part 210 to rotate through magnetic attraction, thereby stably driving the cleaning fan blade 200 to rotate.

[0051] Optionally, the magnetic rotating component 300 has a disc-shaped structure, and the groove 130 has a circular slot-shaped structure. In this way, the disc-shaped magnetic rotating component 300 can provide a uniform magnetic attraction force to attract the magnetic suction part 210 during rotation, while the circular slot-shaped groove 130 can limit the magnetic rotating component 300, allowing it to more stably drive the magnetic suction part 210 to rotate, thereby driving the cleaning fan blade 200 to rotate. Furthermore, the groove 130 reduces the thickness of the lower sidewall of the housing 100, allowing the magnetic attraction force of the magnetic rotating component 300 to better act on the magnetic suction part 210, driving the magnetic suction part 210 to rotate.

[0052] Specifically, the axis of the magnetic rotating component 300 coincides with the axis of the magnetic suction part 210. In this way, the magnetic rotating component 300, the magnetic suction part 210, and the support base 201 are all on the same axis, which improves the rotational stability of the magnetic suction part 210 and the support base 201.

[0053] Specifically, the magnetic rotating component 300 is also a magnet.

[0054] For example, the magnetic poles at both ends of the magnetic rotating member 300 are opposite in direction, that is, one end of the magnetic rotating member 300 is the N pole and the other end is the S pole. The magnetic poles at both ends of the magnetic attraction part 210 are also opposite in direction, that is, one end of the magnetic attraction part 210 is the N pole and the other end is the S pole, and the magnetic poles at the opposite ends of the magnetic rotating member 300 and the magnetic attraction part 210 are opposite.

[0055] Optionally, a drive unit 400 is provided below the magnetic rotating member 300, and the output shaft of the drive unit 400 is connected to the center of the lower side wall of the magnetic rotating member 300. In this way, the drive unit 400 can drive the magnetic rotating member 300 to rotate, which in turn drives the magnetic suction unit 210 to rotate, thereby driving the cleaning fan blade 200 to rotate and clean the inverted powder bowl.

[0056] Specifically, the output shaft of the drive unit 400 is connected to the center of the lower side wall of the magnetic rotating member 300.

[0057] Optionally, the drive unit 400 is a motor. In this way, the magnetic rotating part 300 is driven to rotate by the output shaft of the motor, which in turn drives the magnetic attraction part 210 to rotate.

[0058] Optionally, the drive unit 400 is connected to the lower side wall of the housing 100 via a connecting arm. In this way, the lower side wall of the housing 100 and the connecting arm provide support for the drive unit 400.

[0059] In one embodiment, the powder bowl cleaner further includes a mounting base 500. The mounting base 500 is disposed below the housing 100, and the housing 100 is slidably connected to the mounting base 500, allowing it to slide back and forth along the mounting base 500. Thus, the mounting base 500 provides support for the housing 100, and the housing 100 can slide relative to the mounting base 500, allowing it to slide above the mounting base 500, thereby reducing the space occupied by the powder bowl cleaner.

[0060] Optionally, the housing 100 has a rectangular body structure, and the mounting base 500 has a rectangular plate structure. In this way, the rectangular body structure of the housing 100 and the rectangular plate structure of the mounting base 500 have relatively regular shapes, which facilitates the assembly of the portafilter cleaner into the coffee machine.

[0061] For example, the housing 100 is capable of sliding in the front-to-back direction. When the housing 100 slides forward, it slides forward along the upper sidewall of the mounting base 500 out of the area where the mounting base 500 is located. When the housing 100 slides backward, it slides backward along the upper sidewall of the mounting base 500 until it is directly above the mounting base 500. When the housing 100 slides directly above the mounting base 500, the projection of the housing 100 falls within the projection of the mounting base 500 in the vertical direction.

[0062] Understandably, when the coffee bowl cleaner is used in a coffee machine, the mounting base 500 is fixed inside the coffee machine. Sliding the housing 100 away from the coffee machine means that the housing 100 slides forward, and when the housing 100 faces the coffee machine, it means that the housing 100 slides backward.

[0063] Optionally, the upper sidewall of the mounting base 500 is provided with a guide seat 510, and the lower sidewall of the housing 100 is provided with a retaining seat 140, which is slidably engaged with the outside of the guide seat 510. In this way, the arrangement of the guide seat 510 and the retaining seat 140 makes the sliding connection between the housing 100 and the mounting base 500 more stable. With the cooperation of the guide seat 510 and the retaining seat 140, the housing 100 can slide more stably along the mounting base 500, reducing the risk of the housing 100 shifting during sliding.

[0064] Optionally, the guide seat 510 is a rectangular protrusion formed on the upper side wall of the mounting base 500, and the inner side of the guide seat 510 is hollow. In this way, while the guide seat 510 guides and limits the card holder 140, the drive part 400 and the magnetic rotating part 300 provided on the lower side of the housing 100 can be retracted into the inner side of the guide seat 510 when the housing 100 slides.

[0065] Optionally, a limiting seat 520 is provided at the rear end of the mounting base 500, and the housing 100 can slide toward or away from the limiting seat 520. In this way, when the housing 100 slides backward along the mounting base 500, the limiting seat 520 can block and limit the housing 100, so that the housing 100 stops after sliding to the designated position, and the housing 100 is located directly above the mounting base 500, reducing the space occupied by the housing 100.

[0066] Optionally, the limiting seat 520 is located on the rear side of the upper side wall of the mounting base 500. This provides sufficient space for the sliding of the housing 100.

[0067] Optionally, a spring 530 is provided on one side wall of the housing 100 facing the limiting seat 520. When the housing 100 slides towards the limiting seat 520, the spring 530 can contact the limiting seat 520. In this way, the spring 530 can provide cushioning and assistance for the sliding of the housing 100. When the housing 100 slides backward, the spring 530 can contact the housing 100 before it touches the limiting seat 520, providing cushioning and reducing the risk of damage caused by collision between the housing 100 and the limiting seat 520. When the housing 100 slides forward, the spring 530 can apply a certain elastic force to the housing 100, allowing the housing 100 to slide forward smoothly.

[0068] Optionally, the axis of the spring 530 is parallel to the sliding direction of the housing 100. In this way, when the housing 100 slides backward, the end of the spring 530 can contact the limiting seat 520 in time to provide stable cushioning, and when the housing 100 slides forward, it can better apply the elastic force to the housing 100, so that the housing 100 can slide forward smoothly.

[0069] Optionally, multiple springs 530 are provided, and the multiple springs 530 are evenly arranged in the horizontal direction on the side wall of the housing 100 facing the limiting seat 520. In this way, by providing multiple springs 530, multiple springs 530 can simultaneously provide cushioning and assistance for the sliding of the housing 100, making the cushioning and assistance received by the housing 100 more uniform and improving the cushioning and assistance effect of the housing 100.

[0070] Optionally, the limiting seat 520 has a latching structure 540 on one side wall facing the housing 100, and the housing 100 has a claw 150 on one side wall facing the limiting seat 520. When the housing 100 slides towards the limiting seat 520, the claw 150 can engage with the latch to lock it, thereby restricting the sliding of the housing 100. In this way, by providing the latching structure 540 on the side wall of the limiting seat 520 and the claw 150 on the side wall of the housing 100, the cooperation of the latching structure 540 and the claw 150 can lock the housing 100 when it slides backward to a designated position, preventing the housing 100 from sliding freely. When it is necessary to use the housing 100 to clean the powder container, the housing 100 can be unlocked and pulled forward to the receiving position.

[0071] For example, the latching structure 540 and the latch 150 are press-type elastic self-locking mechanisms, which enable locking and unlocking of the housing 100 by pressing to lock and press to unlock. When the housing 100 is not needed for cleaning the powder bowl, the user pushes the housing 100 backward. When the housing 100 slides to the designated position, the latch 150 engages with the latching structure 540 to lock. When the housing 100 needs to be used for cleaning the powder bowl, the user simply presses the housing 100, causing the latch 150 to disengage from the latching structure 540, and then pulls the housing 100 forward to the designated position.

[0072] Optionally, the latching structure 540 is located in the middle of the side wall of the limiting seat 520, and the claw 150 is located in the middle of the side wall of the housing 100. In this way, when the housing 100 slides toward the limiting seat 520, the claw 150 can accurately engage with the latch, thereby locking the claw 150.

[0073] Combination Figure 8 As shown, in some embodiments, the coffee machine includes: the coffee bowl cleaner of the above embodiments.

[0074] The coffee machine provided in this embodiment of the present disclosure, by incorporating a portafilter cleaner, can efficiently clean the portafilter. Furthermore, the powder inside the portafilter cleaner is easy to remove, improving the cleaning efficiency of powder that falls into the portafilter cleaner.

[0075] Optionally, the coffee machine also includes a main body 600. An installation space is provided at the bottom of the main body 600, within which the mounting base 500 of the portafilter cleaner described in the above embodiment is installed. A pull-out opening is provided on the front side wall of the main body 600, communicating with the installation space. The housing 100 can be pulled out or retracted into the installation space along the pull-out opening. Thus, when the portafilter cleaner is installed in the coffee machine, when cleaning the portafilter is not required, the housing 100 of the portafilter cleaner can be retracted into the installation space, reducing the space occupied by the portafilter cleaner and consequently reducing the space occupied by the coffee machine.

[0076] Optionally, the coffee machine also includes a water tray. The water tray is movably embedded inside the main body and can be pulled out or retracted into the main body along the front side wall. In this way, the water tray can catch coffee drips and other contaminants from the coffee machine, reducing the risk of contamination on the table where the coffee machine is placed.

[0077] Optionally, the front side wall of the housing is also provided with a dispensing nozzle, which allows the prepared coffee liquid to flow out. When the water collection box is removed, the water collection box is located below the dispensing nozzle. In this way, the dispensing nozzle can flow out the prepared coffee liquid, and when the water collection box is removed, it is located below the dispensing nozzle to catch any coffee liquid that splashes out of the dispensing nozzle.

[0078] Optionally, the water collection box and the powder bowl cleaner are arranged side by side inside the housing along a sliding direction perpendicular to the housing 100.
