[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the described order. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0048] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0049] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Please refer to Figures 1 to 4 This invention provides a cleaning apparatus. The cleaning apparatus is used to clean an object to be cleaned, which includes at least one of the following: a preset component of a printing platform, the printing platform itself, and a printed sample.

[0051] The cleaning apparatus includes multiple liquid storage containers 10, a tank 20, and a liquid control device 30. Each of the multiple liquid storage containers 10 has an inner cavity 11 for holding cleaning material. The tank 20 has a cleaning tank 21, and the liquid control device 30 controls the flow of cleaning material between the cleaning tank 21 and the multiple inner cavities 11. The liquid control device 30 controls at least two of the inner cavities 11 of the multiple liquid storage containers 10 to be sequentially connected to the same cleaning tank 21, so that the cleaning tank 21 can sequentially pass cleaning material from at least two inner cavities 11 to clean the object to be cleaned.

[0052] In this embodiment, when the object to be cleaned needs to be cleaned, the liquid control device 30 controls one of the multiple liquid storage containers 10 to connect its inner cavity 11 to the cleaning tank 21, while disconnecting the inner cavities 11 of the other liquid storage containers 10 from the cleaning tank 21. This allows the cleaning material in the inner cavity 11 of the liquid storage container 10 connected to the cleaning tank 21 to be transferred into the cleaning tank 21. Once a preset condition is met, the liquid control device 30 controls the inner cavity 11 of that container to be cleaned to be disconnected from the cleaning tank 21, and the cleaning material in the cleaning tank 21 is used to clean the object. After cleaning, the cleaning material in the cleaning tank 21 can be discharged. Then, the liquid control device 30 controls another liquid storage container 10 to connect its inner cavity 11 to the cleaning tank 21, while disconnecting the inner cavities 11 of the other liquid storage containers 10 from the cleaning tank 21, allowing the cleaning material in the inner cavity 11 of the other liquid storage container 10 to be transferred into the cleaning tank 21 for another cleaning of the object. This allows for multiple cleanings of the object.

[0053] Understandably, the inner cavities 11 of multiple liquid storage containers 10 can all be connected to a cleaning tank 21 to transfer the cleaning material in the inner cavity 11 to the cleaning tank 21, thereby achieving multiple cleanings using a single cleaning tank 21, reducing the number of tanks 20, saving the space required by the tanks 20, and at the same time, the object to be cleaned can always be located in the same cleaning tank 21, and the object to be cleaned does not need to be connected to the drive mechanism, which not only simplifies the installation of the object to be cleaned, but also saves the space occupied by the drive mechanism, reducing the overall size of the cleaning device and realizing the miniaturization design of the cleaning device.

[0054] It is worth noting that the cleaning material is a liquid cleaning material, such as water or ethanol, and the inner cavity 11 of multiple liquid storage containers 10 can contain the same or different cleaning materials.

[0055] For example, the cleaning tank 21 may have one or more first openings. Each inner cavity 11 has one or more second openings, and the second opening of each inner cavity 11 is connected to at least one first opening. When the inner cavity 11 is connected to the cleaning tank 21, the cleaning material in the inner cavity 11 is output to the outside of the inner cavity 11 through the second opening and input into the cleaning tank 21 through the first opening. Specifically, the cleaning tank 21 has only one first opening, which can be connected to a main pipe. Each inner cavity 11 has one second opening, and multiple second openings are respectively connected to the main pipe through a transmission pipe, realizing the connection between the second opening and the first opening of each inner cavity 11. Alternatively, the cleaning tank 21 is provided with multiple first openings, and multiple second openings can correspond one-to-one with multiple first openings. Any first opening is connected to the corresponding second opening through a transmission pipe, realizing the connection between the second opening and the first opening of each inner cavity 11.

[0056] CombinationFigure 5 As shown, in some embodiments, the liquid control device 30 includes a first control valve capable of controlling the connection or disconnection between the cleaning tank and multiple inner cavities. When the first control valve controls the inner cavity 11 of one of the multiple liquid storage containers 10 to connect with the cleaning tank 21, the cleaning material in the inner cavity 11 can be transferred to the cleaning tank 21 under gravity. It can be understood that by ensuring that the liquid storage container 10 and the tank 20 satisfy a corresponding positional relationship in the direction of gravity, the cleaning material in the inner cavity 11 of the liquid storage container 10 can be transferred to the cleaning tank 21 of the tank 20 under gravity, which helps to save energy consumption of the cleaning device.

[0057] For example, the height of the cleaning material in the inner cavity 11 of the liquid storage container 10 from the ground is greater than the height of the first opening of the cleaning tank 21 from the ground, or the height of the inner cavity 11 of the liquid storage container 10 from the ground is greater than the height of the first opening from the ground, so that the cleaning material in the inner cavity 11 of the liquid storage container 10 can be transferred to the cleaning tank 21 under the action of gravity. The specific adjustment can be made according to the actual situation, and no specific limitation is made here.

[0058] Combination Figure 5 and Figure 6 As shown, the cleaning device further includes a lifting assembly 40, which is tractively connected to the tank 20 or multiple liquid storage containers 10. The lifting assembly 40 is used to drive the tank 20 or multiple liquid storage containers 10 to rise and fall, so that the tank 20 and the liquid storage containers 10 can switch between a first state and a second state. When the tank 20 and the liquid storage containers 10 are in the first state, the cleaning material in the inner cavity 11 can be transferred to the cleaning tank 21 under the action of gravity. When the tank 20 and the liquid storage containers 10 are in the second state, the cleaning material in the cleaning tank 21 can be transferred to the inner cavity 11 under the action of gravity. It can be understood that by driving the liquid storage containers 10 or the tank 20 to rise and fall by the lifting assembly 40, the relative position between the liquid storage containers 10 and the tank 20 is adjusted, so that the cleaning material in the inner cavity 11 is supplied to the cleaning tank 21 under the action of gravity, and the cleaning material in the cleaning tank 21 flows back to the inner cavity 11 under the action of gravity.

[0059] In addition, when the cleaning material in the inner cavity 11 is transferred to the cleaning tank 21, and when the cleaning material in the cleaning tank 21 is transferred to the inner cavity 11, the cleaning material can flow through the same transfer pipe, which helps to reduce the connection structure on the tank body 20 and the liquid storage container 10 and simplify the installation steps of the cleaning device.

[0060] For example, when the tank 20 and the liquid storage container 10 are in the first state, the height of the inner cavity 11 is greater than the height of the first opening along the direction of gravity. The cleaning material in the inner cavity 11 can be output from the second opening to the outside of the inner cavity 11 under the action of gravity, and then transported through the transmission pipe connecting the inner cavity 11 and the cleaning tank 21, and input into the cleaning tank 21 from the first opening. When the tank 20 and the liquid storage container 10 are in the second state, the height of the second opening is less than the height of the first opening along the direction of gravity. The cleaning material in the cleaning tank 21 can be output from the first opening to the outside of the inner cavity 11 under the action of gravity, and then transported through the transmission pipe connecting the inner cavity 11 and the cleaning tank 21, and input into the inner cavity 11 from the second opening.

[0061] For example, the cleaning device also includes a housing 50 and a support plate 60. The support plate 60 is disposed inside the housing 50 and spaced apart from the bottom plate of the housing 50. Multiple liquid storage containers 10, a tank 20 and a liquid control device 30 can be disposed inside the housing 50. The tank 20 is supported on the support plate 60 so that the liquid storage containers 10 can be raised and lowered relative to the tank 20 and the relative position between the liquid storage containers 10 and the tank 20 can be adjusted.

[0062] Optionally, when the tank 20 and the liquid storage container 10 are in the first state, the liquid control device 30 controls the inner cavity 11 of the liquid storage container 10 to connect with the cleaning tank 21 of the tank 20. The lifting component 40 can continue to drive the liquid storage container 10 to rise relative to the tank 20, or the lifting component 40 can stop driving the liquid storage container 10 to rise relative to the tank 20. When the tank 20 and the liquid storage container 10 are in the second state, the liquid control device 30 controls the inner cavity 11 of one of the liquid storage containers 10 to connect with the cleaning tank 21 of the tank 20. The lifting component 40 can continue to drive the liquid storage container 10 to fall relative to the tank 20, or the lifting component 40 can stop driving the liquid storage container 10 to fall relative to the tank 20. The specific adjustment can be made according to the actual situation and is not specifically limited here.

[0063] like Figure 3 As shown, in some embodiments, the inner cavity 11 is connected to the bottom of the cleaning tank 21 so as to facilitate the efficient transfer of cleaning material from the cleaning tank 21 to the inner cavity 11.

[0064] Combination Figure 2 As shown, in some embodiments, the cleaning device further includes a mounting plate 70, which is tractively connected to the lifting assembly 40, and multiple liquid storage containers 10 are disposed on the mounting plate 70. Thus, the mounting plate 70 can simultaneously lift and lower multiple liquid storage containers 10 under the drive of the same lifting assembly 40, reducing the number of components in the lifting assembly 40, simplifying its structure, reducing the size of the cleaning device, and facilitating its control.

[0065] For example, the lifting assembly 40 may be a lead screw and nut drive assembly.

[0066] Of course, in other embodiments, multiple liquid storage containers 10 can also be raised and lowered by different lifting components 40.

[0067] In some embodiments, the bottom of the inner cavity 11 of the liquid storage container 10 can communicate with the bottom of the cleaning tank 21. The mounting plate 70 is provided with a clearance hole 71 for avoiding predetermined components. It can be understood that the mounting plate 70 avoids predetermined components through the clearance hole 71, so that the bottom of the inner cavity 11 of the liquid storage container 10 can communicate with the bottom of the cleaning tank 21, so as to facilitate efficient transfer of cleaning materials. At the same time, the mounting plate 70 can stably support the liquid storage container 10 and ensure the stability of the liquid storage container 10.

[0068] For example, the clearance hole 71 can be used to avoid the fixed post protruding from the bottom of the liquid storage container 10. The pipe joint can be connected to the fixed post and the transmission pipe respectively, so that the cleaning material in the inner cavity 11 of the liquid storage container 10 is transmitted to the cleaning tank 21 through the hollow part of the fixed post, the hollow part of the pipe joint and the transmission pipe.

[0069] For example, there may be one or more clearance holes 71.

[0070] like Figure 2 As shown, in one optional embodiment, the first control valve includes multiple solenoid valves, each of which corresponds to a multiple liquid storage container 10. Each solenoid valve is used to control the connection or disconnection between the inner cavity 11 of a liquid storage container 10 and the cleaning tank 21.

[0071] For example, the solenoid valve is located on the transmission pipe that connects the inner cavity 11 and the cleaning tank 21, and the inner cavity 11 and the cleaning tank 21 can be disconnected by clamping the transmission pipe.

[0072] like Figure 7 and Figure 8 As shown, in some embodiments, the inner cavities 11 of multiple liquid storage containers 10 are respectively connected to the cleaning tank 21 via a transmission pipe 200. The first control valve includes a fixed member 31, multiple movable members 32, and an electromagnet 33. The multiple movable members 32 are respectively connected to the fixed member 31 via elastic members 34. Any transmission pipe passes between the fixed member 31 and a movable member 32. The movable member 32 can clamp the transmission pipe with the fixed member 31 under the action of the elastic member 34, thereby controlling the corresponding inner cavity 11 to disconnect from the cleaning tank 21. The electromagnet 33 is located on the side of the movable member 32 away from the fixed member 31 and is connected to the fixed member 31. The electromagnet 33 is used to energize the movable member 32 to provide an attractive force away from the fixed member 31, thereby releasing the transmission pipe between the movable member 32 and the fixed member 31 and controlling the corresponding inner cavity 11 to connect with the cleaning tank 21. Understandably, the first control valve is a normally closed control valve. The moving part 32 and the fixed part 31 are kept in a clamping state of the transmission pipe under the action of the elastic part 34, that is, the inner cavity 11 is kept disconnected from the cleaning tank 21.

[0073] Optionally, the elastic element 34 includes a spring or a sheet.

[0074] For example, such as Figure 7 As shown, the movable part 32 is connected to the fixed part 31 by four elastic parts 34. The four elastic parts 34 are evenly distributed on both sides of the transmission tube, and the two elastic parts 34 on the same side are spaced apart, so that the movable part 32 is evenly stressed, stably clamps the transmission tube, and ensures that the inner cavity 11 of the transmission tube and the cleaning tank 21 are disconnected.

[0075] For example, the movable component 32 is a magnetic component, such as a silicon steel sheet or ferrite. When it is necessary to transfer the cleaning material in the inner cavity 11 to the cleaning tank 21 through the corresponding transfer pipe, the electromagnet 33 can be energized to generate an electromagnetic force. Under the attraction of the electromagnetic force, the movable component 32 resists the elastic force of the elastic component 34, moves closer to the electromagnet 33 and away from the fixed component 31, and the transfer pipe between the movable component 32 and the fixed component 31 is released, so that the transfer pipe connects the corresponding inner cavity 11 and the cleaning tank 21, allowing the cleaning material in the inner cavity 11 to be transferred into the cleaning tank 21. When the preset conditions are met, the energization of the electromagnet 33 can be stopped. Under the action of the elastic force of the elastic component 34, the movable component 32 moves closer to the fixed component 31, re-clamps the transfer pipe with the fixed component 31, and controls the disconnection of the connection between the corresponding inner cavity 11 and the cleaning tank 21.

[0076] like Figure 8 As shown, in one optional embodiment, there are multiple electromagnets 33, and each electromagnet 33 is correspondingly arranged with a plurality of movable parts 32. By energizing one of the multiple electromagnets 33, the electromagnet 33 provides an attractive force to the corresponding movable part 32 away from the fixed part 31, thereby controlling the movable part 32 to move away from the fixed part 31, so that the transmission tube between the movable part 32 and the fixed part 31 connects the corresponding inner cavity 11 and the cleaning tank 21.

[0077] like Figure 7 As shown, in another optional embodiment, there is one electromagnet 33, which is movably connected to the fixed member 31. The electromagnet 33 can move relative to the fixed member 31 to correspond to different movable members 32. By setting one electromagnet 33 movably connected to the fixed member 31, the electromagnet 33 controls the movement of one movable member 32 corresponding to its position. This helps to ensure that at any given time, only the inner cavity 11 of one of the multiple liquid storage containers 10 is connected to the cleaning tank 21, while the inner cavities 11 of the other liquid storage containers 10 are disconnected from the cleaning tank 21.

[0078] For example, the cleaning device also includes a housing 50, an electromagnet 33 movably connected to a base plate, a fixing member 31 spaced apart on the side of the electromagnet 33 away from the base plate and connected to the base plate of the housing 50 through a fixing plate, and multiple movable members 32 located between the electromagnet 33 and the fixing member 31 and respectively connected to the fixing member 31 through an elastic member 34.

[0079] For example, multiple movable parts 32 are spaced apart along the length of the fixed part 31, and an electromagnet 33 is slidably connected to the base plate so as to slide relative to the fixed part 31 along the length of the fixed part 31. The electromagnet 33 can slide to correspond to one of the multiple movable parts 32, thereby achieving adsorption of the movable part 32 and connecting the corresponding inner cavity 11 and the cleaning tank 21.

[0080] For example, the electromagnet 33 is slidably connected to the base plate via a lead screw and nut transmission assembly.

[0081] Furthermore, the first control valve 30 also includes a conductive element 35, which is used to conduct electricity. The electromagnet 33 is provided with an electrical connector 331, which can drive the electrical connector 331 to slide. The electromagnet 33 is in contact with the conductive element 35 through the electrical connector 331.

[0082] Furthermore, there are multiple conductive elements 35, which are spaced apart along the sliding direction of the electromagnet 33. When the electromagnet 33 slides to correspond to different movable elements 32, the electromagnet 33 can make contact with one of the multiple conductive elements 35. When the electromagnet 33 slides to another movable element 32 and is offset from the currently corresponding movable element 32, the electromagnet 33 disconnects from the conductive element 35, ensuring that the electromagnet 33 remains de-energized at this time. This prevents the electromagnet 33 from simultaneously generating an attraction force on two movable elements 32, which could lead to leakage of cleaning material from the two transmission tubes.

[0083] In some embodiments, the liquid control device 30 includes a second control valve and a plurality of bidirectional pumps, each bidirectional pump being connected to an inner cavity 11 and a cleaning tank 21, such that the bidirectional pumps can control the transfer of cleaning material in the inner cavity 11 to the cleaning tank 21, or control the transfer of cleaning material in the cleaning tank 21 to the inner cavity 11. The second control valve can control the connection or disconnection between one of the inner cavities 11 of the cleaning tank 21 and the bidirectional pump. It is understood that the bidirectional pumps enable the supply of cleaning material from the inner cavity 11 to the cleaning tank 21, and the return of cleaning material from the cleaning tank 21 to the inner cavity 11.

[0084] For illustrative purposes, let's take the example of the second control valve controlling the connection or disconnection between the cleaning tank and the bidirectional pump. When cleaning is required, the second control valve can connect one of the multiple bidirectional pumps to the cleaning tank 21, while disconnecting the others. The bidirectional pump connected to the cleaning tank 21 is then activated, allowing the cleaning material in its connected cavity 11 to be transferred into the cleaning tank 21. Once a preset condition is met, the second control valve disconnects the bidirectional pump from the cleaning tank 21, stopping the transfer and allowing the cleaning material in the cleaning tank 21 to clean the object. After one cleaning cycle, the second control valve can reconnect the same bidirectional pump to the cleaning tank 21, activating it to transfer the cleaning material back into its original cavity 11, achieving material return. After the recycling is completed, the second control valve can be used to control another of the multiple bidirectional pumps to connect to the cleaning tank 21. The bidirectional pump is started to transfer the cleaning material in the inner cavity 11 of another liquid storage container 10 to the cleaning tank 21, so as to achieve secondary cleaning of the object to be cleaned.

[0085] Specifically, the structure of the second control valve can be referred to the first control valve described above, and will not be repeated here.

[0086] In some embodiments, the cleaning apparatus further includes a recycling mechanism for recycling the cleaning material in the cleaning tank 21 to the corresponding inner cavity 11.

[0087] In one exemplary embodiment, the liquid storage container 10 includes a first liquid storage container 10 and a second liquid storage container 10. Cleaning material in the inner cavity 11 of the first liquid storage container 10 is transferred to a cleaning tank 21. After cleaning the object to be cleaned using the cleaning material in the cleaning tank 21, the cleaning material in the cleaning tank 21 can be recycled back to the inner cavity 11 of the first liquid storage container 10 via a recycling mechanism. Then, the cleaning material in the inner cavity 11 of the second liquid storage container 10 is transferred to the cleaning tank 21. After cleaning the object to be cleaned using the cleaning material in the cleaning tank 21, the cleaning material in the cleaning tank 21 can be recycled back to the inner cavity 11 of the second liquid storage container 10 via the recycling mechanism.

[0088] In another exemplary embodiment, the liquid storage container 10 includes a first liquid storage container 10 and a second liquid storage container 10. Cleaning material in the inner cavity 11 of the first liquid storage container 10 is transferred to a cleaning tank 21. After cleaning the object to be cleaned using the cleaning material in the cleaning tank 21, the cleaning material in the cleaning tank 21 can be discharged from the cleaning tank 21 and collected as waste liquid. Then, the cleaning material in the inner cavity 11 of the second liquid storage container 10 is transferred to the cleaning tank 21. After cleaning the object to be cleaned using the cleaning material in the cleaning tank 21, the cleaning material in the cleaning tank 21 can be recycled back to the inner cavity 11 of the first liquid storage container 10 via a recycling mechanism.

[0089] Optionally, the recycling mechanism can process the recycled cleaning material and then recycle it into the corresponding inner cavity 11, or it can directly recycle the recycled cleaning material into the corresponding inner cavity 11. No specific limitation is made here.

[0090] For example, the recycling mechanism includes the lifting assembly 40 mentioned above. The lifting assembly 40 drives the liquid storage container 10 or the tank 20 to rise and fall, so as to recycle the cleaning material in the cleaning tank 21 to the corresponding inner cavity 11.

[0091] For example, the recycling mechanism may include the above-mentioned multiple bidirectional pumps, each bidirectional pump being connected to the first opening of the cleaning tank 21 and the second opening of the liquid storage container 10. The bidirectional pumps can forward transfer the cleaning material in the inner cavity 11 of the liquid storage container 10 to the cleaning tank 21, and can also reverse transfer the cleaning material in the cleaning tank 21 to the liquid storage container 10, thereby realizing the recycling of the cleaning material in the cleaning tank 21.

[0092] For example, the cleaning tank 21 has a third opening located at the bottom of the cleaning tank 21. The recycling mechanism can communicate with the third opening so that the cleaning material in the cleaning tank 21 is output to the outside of the cleaning tank 21 through the third opening and recycled to the corresponding inner cavity 11 by the recycling mechanism.

[0093] In some embodiments, the cleaning device further includes a liquid level sensor 80, which is disposed in the tank 20. The liquid level sensor 80 is used to detect the liquid level of the cleaning material in the cleaning tank 21, so as to control the cleaning device according to the liquid level of the cleaning material in the cleaning tank 21.

[0094] For example, after the liquid control device 30 controls the inner cavity 11 of one of the multiple liquid storage containers 10 to connect with the cleaning tank 21, the cleaning material in the inner cavity 11 is transferred to the cleaning tank 21. The liquid level sensor 80 can detect the liquid level of the cleaning material in the cleaning tank 21. When the liquid level of the cleaning material in the cleaning tank 21 meets the preset liquid level, the liquid control device 30 can control the inner cavity 11 to disconnect from the cleaning tank 21 and stop the transfer of cleaning material into the cleaning tank 21.

[0095] For example, the level sensor 80 includes a photoelectric level sensor or an ultrasonic level sensor.

[0096] In one optional embodiment, the cleaning device further includes an oscillator 90, which may be disposed in the housing 50 and the tank 20 disposed in the oscillator 90. The oscillator 90 is used to drive the cleaning material in the tank 20 and the cleaning tank 21 to oscillate, so as to make the cleaning material in the cleaning tank 21 flow and improve the cleaning efficiency of the object to be cleaned.

[0097] For example, the oscillator 90 may be a piezoelectric oscillator, a pneumatic oscillator, or a mechanical oscillator.

[0098] For example, such as Figure 3 As shown, the top of the oscillator 90 is provided with a slot 91, and the bottom of the slot 20 is formed with a block 22. The block 22 and the slot 91 are engaged to ensure the connection stability between the slot 20 and the oscillator 90.

[0099] For example, the block 22 is provided with a guide hole 23, one end of which is connected to the cleaning tank 21, and the other end extends to the outer surface of the block 22 to connect to the inner cavity 11 of the liquid storage container 10. The oscillator 90 is also provided with a relief groove 92 that communicates with the slot 91. The slot 91 is located on one side of the relief groove 92 in the horizontal direction to avoid the opening of the guide hole 23.

[0100] For example, the outer surface of the card block 22 is provided with a fixing post extending in the horizontal direction. The hollow part of the fixing post forms part of the guide hole 23. The pipe joint can connect the fixing post and the transmission pipe so that the cleaning material in the inner cavity 11 of the liquid storage container 10 can be transmitted to the cleaning tank 21 through the transmission pipe, the hollow part of the pipe joint and the guide hole 23.

[0101] In another optional embodiment, the cleaning device further includes an agitator, which is at least partially located within the cleaning tank 21. The agitator is used to stir the cleaning material within the cleaning tank 21 to make the cleaning material flow within the cleaning tank 21 and improve the cleaning efficiency of the object to be cleaned.

[0102] Furthermore, the stirrer includes a magnetic stirrer, which includes a stirrer body and a magnetic stir bar. The magnetic stir bar can be located inside the cleaning tank 21, while the stirrer body is located outside the tank 20. The stirrer body can generate electromagnetic force to drive the magnetic stir bar to stir the cleaning material in the cleaning tank 21.

[0103] Furthermore, the tank body 20 is provided with an installation groove that communicates with the cleaning tank 21. The installation groove is located at the bottom of the cleaning tank 21, the magnetic stir bar is located inside the installation groove, and the stirrer body is located below the tank body 20 and is set accordingly to the magnetic stir bar.

[0104] In another optional embodiment, the cleaning apparatus further includes an ultrasonic generator for generating sound waves to vibrate the cleaning material in the cleaning tank 21, thereby improving the cleaning efficiency of the object to be cleaned.

[0105] In some embodiments, the cleaning device further includes a top cover 100, which is detachably connected to the tank 20. The top cover 100 is used to cover or expose the opening of the cleaning tank 21. It is understood that the object to be cleaned can be placed in the cleaning tank 21 through the opening. When cleaning the object, the top cover 100 can be used to cover the opening of the cleaning tank 21 to prevent the cleaning material in the cleaning tank 21 from splashing out or evaporating.

[0106] For example, the top cover 100 and the groove 20 are sealed together by a seal.

[0107] For example, the level sensor 80 may be located on the top cover 100.

[0108] For example, the top cover 100 is provided with a viewing window area, through which the cleaning status of the items to be cleaned in the cleaning tank 21 can be observed.

[0109] This invention also provides a cleaning method for an object to be cleaned based on a cleaning device. The object to be cleaned includes at least one of the following: a preset component of a printing platform, a printing platform, and a printed sample; the cleaning device includes multiple liquid storage containers, a tank, and a liquid control device, wherein each of the multiple liquid storage containers has an inner cavity, and the multiple liquid storage containers include a first liquid storage container and a second liquid storage container. The cleaning method includes steps S101 to S105.

[0110] S101. Control the liquid control device to connect the cleaning tank of the tank body and the inner cavity of the first liquid storage container, so that the cleaning material in the inner cavity of the first liquid storage container is transferred to the cleaning tank.

[0111] For example, the liquid control device includes a first control valve, which includes multiple solenoid valves, each corresponding to a multiple liquid storage container. The cleaning tank and the inner cavity of the first liquid storage container can be connected by controlling the opening of the solenoid valve corresponding to the first liquid storage container. Alternatively, the first control valve includes a fixed component, a movable component, and an electromagnet as described above. The cleaning tank and the inner cavity of the first liquid storage container can be connected via the transmission pipe by controlling the electromagnet to attract the movable component corresponding to the transmission pipe connected to the first liquid storage container.

[0112] S102. When the preset conditions are met, the liquid control device is controlled to disconnect the inner cavity connecting the cleaning tank and the first liquid storage container, and the cleaning material in the cleaning tank is used to clean the object to be cleaned.

[0113] For example, the preset conditions may include at least one of the following: the cleaning material in the cleaning tank meets a preset liquid level, and the liquid control device controls an inner cavity to be connected to the cleaning tank for a preset time.

[0114] In some embodiments, the cleaning device further includes a liquid level sensor, which is disposed in the tank. The liquid level sensor is used to detect the liquid level data of the cleaning material in the cleaning tank. The preset condition is that the liquid level data is greater than or equal to a preset liquid level. That is, when the liquid level of the cleaning material in the cleaning tank meets the preset liquid level, the inner cavity of the first liquid storage container is disconnected from the cleaning tank, and the transfer of cleaning material into the cleaning tank is stopped.

[0115] For example, the cleaning material in the cleaning tank can be used to clean the object to be cleaned by immersing the object to be cleaned in the cleaning material in the cleaning tank for a preset time, and / or by using a vibrator to drive the tank body and the cleaning material in the cleaning tank to vibrate, and / or by using a stirrer to agitate the cleaning material in the cleaning tank, and / or by using an ultrasonic generator to generate sound waves to make the cleaning material in the cleaning tank vibrate, so that the cleaning material in the cleaning tank can clean the object to be cleaned.

[0116] S103. Control the discharge of the cleaning material in the cleaning tank.

[0117] S104. Control the liquid control device to connect the cleaning tank and the inner cavity of the second liquid storage container in the same tank body, so that the cleaning material in the inner cavity of the second liquid storage container is transferred to the cleaning tank.

[0118] S105. When the preset conditions are met, the liquid control device is controlled to disconnect the inner cavity connecting the cleaning tank and the second liquid storage container, and the cleaning material in the cleaning tank is used again to clean the object to be cleaned.

[0119] Steps S104 and S105 can be referred to the descriptions of steps S101 and S102, and will not be repeated here.

[0120] It is worth noting that the number of times the object to be cleaned is to be cleaned can be less than or equal to the number of liquid storage containers in the cleaning device. The object can be cleaned sequentially using the cleaning material from the inner cavities of at least two of the multiple liquid storage containers. In other words, the number of times the object to be cleaned can be adjusted according to the actual situation. For example, the cleaning device includes five liquid storage containers, each containing water of different purities. The object to be cleaned in the cleaning tank can be cleaned sequentially using water from two or four of the containers.

[0121] Understandably, this cleaning method allows for the sequential cleaning of the object to be cleaned using the cleaning material within the inner cavities of at least two of multiple liquid storage containers, enabling multiple cleanings. Since the cleaning material within the inner cavities of all liquid storage containers is transferred to a single cleaning tank, multiple cleanings can be performed using a single tank, reducing the number of tanks and saving space. Furthermore, the object to be cleaned can always remain within the same cleaning tank, eliminating the need for connection to the drive mechanism. This simplifies installation and saves space occupied by the drive mechanism, resulting in a smaller overall size and more compact design of the cleaning device.

[0122] In some embodiments, the cleaning material inside the cavity of the target liquid storage container can be transferred to the cleaning tank through the first opening under gravity, thereby saving energy consumption of the cleaning device.

[0123] Furthermore, the liquid control device includes a first control valve capable of controlling the connection or disconnection between the cleaning tank and multiple internal cavities. The cleaning device also includes a lifting assembly, which is tractively connected to multiple liquid storage containers. The cleaning method further includes: controlling the lifting assembly to raise the liquid storage containers so that the cleaning material in the internal cavity of the liquid storage containers can be transferred to the cleaning tank under gravity. Controlling the discharge of cleaning material in the cleaning tank includes: controlling the lifting assembly to lower the liquid storage containers so that the cleaning material in the cleaning tank can be transferred to the internal cavity of the liquid storage containers under gravity; controlling the first control valve to connect the internal cavity of the target liquid storage container and the cleaning tank so that the cleaning material in the cleaning tank can be transferred to the internal cavity of the liquid storage container under gravity.

[0124] Understandably, by using the lifting assembly to raise and lower the liquid storage container, the relative position between the liquid storage container and the tank is adjusted, so that the cleaning material in the inner cavity of the liquid storage container is supplied to the cleaning tank of the tank under the action of gravity, and the cleaning material in the cleaning tank flows back to the inner cavity of the target liquid storage container under the action of gravity.

[0125] For example, before executing step S101, the lifting assembly is controlled to raise the first liquid storage container, so that when the first control valve connects the cleaning tank and the inner cavity of the first liquid storage container, the cleaning material in the inner cavity of the first liquid storage container can be transferred to the cleaning tank under gravity. During step S103, the lifting assembly is controlled to lower the first liquid storage container, so that when the first control valve connects the cleaning tank and the inner cavity of the first liquid storage container, the cleaning material in the cleaning tank can be transferred to the inner cavity of the first liquid storage container under gravity. Before executing step S104, the lifting assembly is controlled to raise the second liquid storage container, so that when the first control valve connects the inner cavities of the cleaning tank and the second liquid storage container, the cleaning material in the inner cavity of the second liquid storage container can be transferred to the cleaning tank under gravity.

[0126] In some embodiments, the cleaning device further includes a drain pipe and a clamp valve. The drain pipe connects to a drain outlet at the bottom of the cleaning tank and a waste liquid tank. When the cleaning material in the inner cavity of the storage container is transferred to the cleaning tank, and when the object to be cleaned is cleaned by the cleaning material in the cleaning tank, the clamp valve clamps the drain pipe, disconnecting the cleaning tank from the waste liquid tank. When the cleaning material in the cleaning tank is discharged, the clamp valve releases the drain pipe, connecting the cleaning tank and the waste liquid tank. The waste liquid tank can be located below the cleaning tank, allowing the cleaning material in the cleaning tank to be transferred to the waste liquid tank under gravity.

[0127] The method of this invention can be used in a wide variety of general-purpose or special-purpose computer system environments or configurations.
