[0059] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0060] Figures 1-5 This diagram illustrates a structural diagram of a 3D printing cleaning apparatus according to an embodiment of this application. Figures 1-5 As shown, the cleaning device may include:

[0061] The outer casing 100 is disposed inside the container;

[0062] Impeller mechanism 200 is mounted on housing 100 and is used to agitate the cleaning liquid in the container;

[0063] The launch housing 300 is disposed outside the container, and the launch housing 300 corresponds to the position of the housing 100;

[0064] The magnetic assembly 400 has a portion disposed inside the housing 100 and another portion disposed inside the emitting housing 300. The housing 100 and the emitting housing 300 are attached to the container by the magnetic assembly 400.

[0065] In this embodiment, during use, the outer shell 100 is placed inside a container of the corresponding size, and then the launching shell 300 is attached to the outside of the container by the magnetic suction component 400. The 3D printed model is placed into the container and a cleaning solution (mainly IPA cleaning agent or alcohol, the main component of IPA cleaning agent is isopropanol) is added. The launching shell 300 controls the rotation of the impeller mechanism 200, thereby driving the impeller mechanism 200 to rotate, causing the water flow to form a vortex structure to clean the model.

[0066] By designing the outer shell 100 and the transmitting shell 300 as separate structures and attaching them to the container via the magnetic component 400, users can freely choose non-metallic containers such as plastic boxes or glass tanks according to the size of the printed model or available resources. Compared with traditional magnetic impeller devices or ultrasonic cleaners, this cleaning device significantly reduces the structural volume; it supports deployment in a more compact space, is easy to carry and store, and is easy to replace independently. If the impeller mechanism 200 fails, there is no need to replace the entire machine; no high-value special cleaning tanks or original parts are required, and replacement parts can be made or printed from common materials, greatly reducing the user's maintenance burden.

[0067] The modular housing 100 and the launch housing 300 can be freely combined to create a cleaning environment that best suits the user's model; the DIY-friendly hardware structure enhances the interaction and sense of value between the product and the user.

[0068] like Figures 1-2 As shown, in one embodiment,

[0069] The impeller mechanism 200 includes:

[0070] Stator 210, stator 210 is mounted on housing 100;

[0071] Rotor 220 is rotatably mounted on stator 210;

[0072] An annular magnet 230 is embedded in the rotor 220 so that the rotor 220 interacts with the magnetic field of the stator 210.

[0073] Bearing 240 is disposed between stator 210 and rotor 220.

[0074] In this embodiment, the rotor 220 is a one-piece molded plastic structure with an embedded annular magnet 230 for interacting with the magnetic field of the stator 210.

[0075] The stator 210 is fixed inside the housing 100 and consists of multi-slot windings. It is encapsulated with potting compound to ensure long-term stable operation underwater. The rotor 220 and the stator 210 are supported by bearings 240 to form rotational freedom. The housing 100 covers the entire motor structure.

[0076] The stator 210 is fixed inside the outer casing 100 and waterproof encapsulated by potting material. The potting process achieves a fully sealed structure for the entire machine, allowing it to work while immersed in cleaning solution for extended periods. The motor and drive circuit are powered wirelessly, eliminating any physical exposed interfaces and common failure modes such as short circuits caused by liquid ingress.

[0077] The housing 100 is equipped with a wireless power receiving coil and a rectifier and voltage regulator circuit inside. It receives high-frequency electromagnetic energy from the transmitter of the transmitting housing 300 and converts it into DC power to power the driver board 270. The power supply method is non-contact, ensuring that the module is fully enclosed and has no interface.

[0078] like Figures 1-2 As shown, in one embodiment,

[0079] The impeller mechanism 200 also includes:

[0080] A plurality of fixing blocks 250 are spaced apart on the rotor 220;

[0081] Several blades 260 are detachably mounted on corresponding fixed blocks 250. When the rotor 220 rotates relative to the stator 210, the blades 260 rotate to agitate the cleaning fluid.

[0082] In this embodiment, the blades 260 are detachably mounted on the fixing block 250, and the number of blades 260 can be adjusted according to actual needs. Users can replace, reduce, or customize the shape according to cleaning requirements. This structure balances easy cleaning, low cost, and functional adjustability.

[0083] The rotor 220 is directly connected to the impeller blade 260 without any intermediate transmission mechanism, thus realizing the integration of the rotor 220 and the impeller.

[0084] The blade 260 is directly integrated with the rotor 220, eliminating the traditional motor + drive shaft or magnetic coupling structure, reducing power loss; the structure is simpler.

[0085] like Figures 1-2 and Figure 5 As shown, in one embodiment,

[0086] The blade 260 has a groove 261 that is adapted to the fixing block 250.

[0087] In this embodiment, the fixing block 250 is fixedly mounted on the rotor 220 by a protrusion. The cross-sectional area of ​​the protrusion is smaller than the area of ​​the fixing block 250. The blade 260 has a groove 261 that is adapted to the fixing block 250, and also has an inclined locking block. The distance between the locking block and the fixing block 250 and the protrusion is adapted to facilitate the locking of the blade 260 and the fixing block 250.

[0088] The blade 260 is detachable, encouraging users to customize the cleaning intensity. Users can choose to reduce the number of blades, modify the shape of the blade 260, or drill holes in the blade 260 to introduce the bubble cleaning function according to the characteristics of the object being cleaned. Compared with fixed injection molded impellers, it greatly improves the functional flexibility and maintenance convenience.

[0089] like Figures 1-2 As shown, in one embodiment,

[0090] The impeller mechanism 200 also includes:

[0091] The drive board 270 is disposed inside the housing 100. The drive board 270 is used to receive power and drive the rotor 220.

[0092] In this embodiment, the housing 100 covers the drive plate 270 and is sealed and protected by structural adhesive or studs. The drive plate 270 has a motor to drive the rotor 220 to rotate. The drive plate 270 is installed inside the housing 100 and is responsible for receiving power, driving the motor, and executing control logic. This device achieves a highly modular and fully enclosed structure by tightly integrating the motor stator 210 and the impeller mechanism 200 drive structure within the same housing 100, significantly improving system reliability and adaptability.

[0093] like Figure 1 and Figure 3 As shown, in one embodiment, it further includes:

[0094] The transmitting coil PCB500 is disposed inside the transmitting housing 300. When the transmitting housing 300 and the housing 100 are attracted by the magnetic attraction component 400, the transmitting coil PCB500 corresponds to the driving board 270.

[0095] In this embodiment, the transmitting coil PCB500 generates an alternating magnetic field through a high-frequency circuit to wirelessly power the driver board 270. The wireless power supply uses a non-contact method for energy transmission, which meets the isolation power supply requirements of the underwater impeller module.

[0096] The transmitter housing 300 is located at the bottom of the container, while the transmitter coil PCB500 and excitation circuit are located inside. The transmitter supports communication and power management by connecting to a control terminal via a TYPE-C cable.

[0097] like Figures 2-4 As shown, in one embodiment,

[0098] The magnetic assembly 400 includes:

[0099] A first strong magnet 410 is disposed inside the outer casing 100;

[0100] The second strong magnet 420 is disposed inside the transmitting shell 300. When the shell 100 and the strong magnet shell 100 are disposed on the container, the first strong magnet 410 and the second strong magnet 420 are attracted to each other, so that the shell 100 and the transmitting shell 300 are respectively fixed on the container.

[0101] The third strongest magnet is 430.

[0102] In this embodiment, a first strong magnet 410 is provided inside the outer casing 100, corresponding to a second strong magnet 420 inside the transmitting outer casing 300. The outer casing 100 and the transmitting outer casing 300 are fixed through the container by the first strong magnet 410 and the second strong magnet 420, thereby aligning the transmitting coil PCB 500 with the driving board 270.

[0103] like Figure 1 and Figure 4 As shown, in one embodiment, it further includes:

[0104] The control mechanism 600 is used to control the transmitting coil PCB 500, and the third strong magnet 430 is set inside the control mechanism 600.

[0105] The control mechanism 600 includes:

[0106] Main controller housing 610;

[0107] The main control PCB 620 is located inside the main control housing 610;

[0108] The button assembly is mounted on the main control housing 610, and the buttons are in contact with the main control PCB 620.

[0109] In this embodiment, the main control PCB620 integrates a microcontroller, power regulation and status display circuit;

[0110] The button assembly can be configured with functions such as working time, start / pause, etc.

[0111] The main control PCB620 is connected to the transmitting coil PCB500 via a connecting cable to provide power and transmit control signals. After the user sets the working time and starts the operation, the transmitting coil PCB500 controls the driver board 270 to start, run, and switch according to the commands.

[0112] The control mechanism 600 also includes a wireless transmitter board, which is connected to the transmitter coil PCB 500;

[0113] The main control PCB620 adopts an external module structure and is connected to the transmitting coil PCB500 via a TYPE-C cable, enabling functions such as timed operation and status indication.

[0114] A single control terminal can be connected in series to control multiple transmitters, enabling extended layouts such as "one to two" or "one to three"; suitable for lightweight automation scenarios such as small studios and printing farms that require batch cleaning.

[0115] like Figure 4 As shown, in one embodiment,

[0116] The third strong magnet 430 is installed inside the main control housing 610 so that the main control housing 610 can be attracted to the metal surface.

[0117] In this embodiment, a third strong magnet 430 is provided inside the main control housing 610 for adsorption onto the metal surface, and can be arbitrarily fixed to the barrel wall or tabletop by means of a matching adhesive metal sheet.

[0118] The user places the outer casing 100 into the bottom of any non-metallic container; places the model or printing platform into the container and adds cleaning fluid; the launch casing 300 is placed outside the container and fixed in place by magnetic attraction with the outer casing 100.

[0119] After the adapter is connected to the main control PCB 620 of the main control housing 610, the main control PCB 620 supplies power to the transmitting coil PCB 500 in the wireless module through the connecting cable. The wireless transmitter board in the wireless module generates an alternating magnetic field through the transmitting coil PCB 500 after being powered on. The receiving coil of the drive board 270 inside the housing 100 is in the magnetic field, and according to Faraday's law of electromagnetic induction, a voltage is induced. This induced voltage is rectified, filtered, and regulated by the wireless receiver board before being supplied to the motor drive board 270. After the countdown is set and started, the impeller begins to rotate, agitating the cleaning fluid to form a circulating flow, effectively cleaning the model. The motor drive board 270 has a built-in periodic cyclic cleaning program that switches the cleaning direction every minute. The entire system is controlled solely by the main control PCB 620, achieving a stable cleaning mode that requires no complex communication and relies solely on power switching. If the user uses the matching modular cleaning basket, the model protection and impeller anti-collision capability can be further improved, suitable for customized cleaning processes of different model sizes and platform structures.
