In order to ensure that impurities on the printing platform and printed samples can be completely removed, some cleaning devices will be equipped with a cleaning process.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

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

[0049] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

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

[0051] The cleaning device includes a plurality of liquid storage containers 10, a tank body 20, and a liquid control device 30. The plurality of liquid storage containers 10 are each provided with an inner cavity 11 for accommodating cleaning materials. The tank body 20 is provided with a cleaning tank 21, and the liquid control device 30 can control the cleaning materials to flow through the cleaning tank 21 and the plurality of inner cavities 11. The liquid control device 30 is used to control the inner cavities 11 of at least two of the plurality of liquid storage containers 10 to be connected to the same cleaning tank 21 in sequence, so that the cleaning tank 21 can clean the object to be cleaned through the cleaning materials in at least two inner cavities 11 in sequence.

[0052] The cleaning device of this embodiment can control the inner cavity 11 of one of the multiple liquid storage containers 10 to communicate with the cleaning tank 21 through the liquid control device 30 when the object to be cleaned needs to be cleaned, while the inner cavities 11 of the other liquid storage containers 10 are disconnected from the cleaning tank 21, so that the cleaning material in the inner cavity 11 of the one liquid storage container 10 connected to the cleaning tank 21 can be transferred to the cleaning tank 21, until the preset conditions are met, the inner cavity 11 of the one liquid storage container 10 is controlled to be disconnected from the cleaning tank 21 through the liquid control device 30, and the object to be cleaned is cleaned with the cleaning material in the cleaning tank 21. After cleaning, the cleaning material in the cleaning tank 21 can be discharged from the cleaning tank 21, and then the inner cavity 11 of another liquid storage container 10 is controlled to communicate with the cleaning tank 21 through the liquid control device 30 again, while the inner cavities 11 of the other liquid storage containers 10 are disconnected from the cleaning tank 21, so that the cleaning material in the inner cavity 11 of the other liquid storage container 10 is transferred to the cleaning tank 21, so that the object to be cleaned can be cleaned again, so that multiple cleaning of the object to be cleaned can be achieved.

[0053] It can be understood that the inner cavities 11 of multiple liquid storage containers 10 can all be connected to a cleaning tank 21 to transfer the cleaning materials in the inner cavity 11 to the cleaning tank 21, thereby using one cleaning tank 21 to achieve multiple cleanings, reducing the number of tank bodies 20, and saving the space required for the tank bodies 20. At the same time, the objects to be cleaned can always be located in the same cleaning tank 21, and the objects to be cleaned do not need to be connected to a driving mechanism, which not only simplifies the installation of the objects to be cleaned, but also saves the space occupied by the driving mechanism, reduces the volume of the cleaning device as a whole, and realizes a miniaturized design of the cleaning device.

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

[0055] Exemplarily, 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 is input into the cleaning tank 21 through the first opening. Specifically, the cleaning tank 21 has only one first opening, and the first opening can be connected to a main pipe. Each inner cavity 11 has a second opening, and the multiple second openings are connected to the main pipe through a transmission pipe, respectively, to achieve the connection between the second opening of each inner cavity 11 and the first opening. Alternatively, the cleaning tank 21 is provided with multiple first openings, and the multiple second openings can correspond one-to-one to the multiple first openings. Any first opening is connected to the corresponding second opening through a transmission pipe, to achieve the connection between the second opening of each inner cavity 11 and the first opening.

[0056] Combination Figure 5 As shown, in some embodiments, the liquid control device 30 includes a first control valve, which can control the connection or disconnection between the cleaning tank and the multiple inner cavities. When the first control valve controls the inner cavity 11 of one of the multiple liquid storage containers 10 to be connected to the cleaning tank 21, the cleaning material in the inner cavity 11 can be transferred to the cleaning tank 21 under the action of gravity. It can be understood that by making the liquid storage container 10 and the tank body 20 meet the corresponding positional relationship in the gravity direction, 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 body 20 under the action of gravity, which is conducive to saving energy consumption of the cleaning device.

[0057] Exemplarily, the height from the liquid level of the cleaning material in the inner cavity 11 of the liquid storage container 10 to the ground is greater than the height from the first opening of the cleaning tank 21 to the ground, or the height from the inner cavity 11 of the liquid storage container 10 to the ground is greater than the height from the first opening to 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 actual conditions and is not specifically limited here.

[0058] Combination Figure 5 and Figure 6 As shown, further, the cleaning device also includes a lifting assembly 40, which is transmission-connected to the tank body 20 or multiple liquid storage containers 10, and the lifting assembly 40 is used to drive the tank body 20 or multiple liquid storage containers 10 to lift and lower, so that the tank body 20 and the liquid storage container 10 are switched between the first state and the second state. When the tank body 20 and the liquid storage container 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 body 20 and the liquid storage container 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 container 10 or the tank body 20 to lift and lower, adjusting the relative position between the liquid storage container 10 and the tank body 20, 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 is beneficial 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] Exemplarily, when the tank body 20 and the liquid storage container 10 are in the first state, along the gravity direction, the height of the inner cavity 11 is greater than the height of the first opening, and 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 is transmitted through the transmission tube connecting the inner cavity 11 and the cleaning tank 21, and is input into the cleaning tank 21 from the first opening. When the tank body 20 and the liquid storage container 10 are in the second state, along the gravity direction, the height of the second opening is less than the height of the first opening, and 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 is transmitted through the transmission tube connecting the inner cavity 11 and the cleaning tank 21, and is input into the inner cavity 11 from the second opening.

[0061] Exemplarily, the cleaning device also includes a shell 50 and a support plate 60, the support plate 60 is arranged in the shell 50 and is spaced apart from the bottom plate of the shell 50, a plurality of liquid storage containers 10, a tank body 20 and a liquid control device 30 can be arranged in the shell 50, and the tank body 20 is supported on the support plate 60 so that the liquid storage container 10 can be raised and lowered relative to the tank body 20 and the relative position between the liquid storage container 10 and the tank body 20 can be adjusted.

[0062] Optionally, when the tank body 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 communicate with the cleaning tank 21 of the tank body 20, and the lifting assembly 40 can continue to drive the liquid storage container 10 to rise relative to the tank body 20, or the lifting assembly 40 can stop driving the liquid storage container 10 to rise relative to the tank body 20. When the tank body 20 and the liquid storage container 10 are in the second state, the liquid control device 30 controls the inner cavity 11 of a liquid storage container 10 to communicate with the cleaning tank 21 of the tank body 20, and the lifting assembly 40 can continue to drive the liquid storage container 10 to descend relative to the tank body 20, or the lifting assembly 40 can stop driving the liquid storage container 10 to descend relative to the tank body 20, which can be adjusted according to actual conditions 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 that the cleaning material in the cleaning tank 21 can be efficiently transferred to the inner cavity 11 .

[0064] Combination Figure 2 As shown, in some embodiments, the cleaning device further comprises a mounting plate 70, which is transmission-connected to the lifting assembly 40, and a plurality of liquid storage containers 10 are arranged on the mounting plate 70. In this way, the mounting plate 70 can simultaneously drive the plurality of liquid storage containers 10 to be lifted and lowered under the drive of the same lifting assembly 40, thereby reducing the number of components of the lifting assembly 40, simplifying the structure of the lifting assembly 40, reducing the volume of the cleaning device, and facilitating the control of the cleaning device.

[0065] Exemplarily, the lifting assembly 40 may adopt a screw-nut transmission assembly.

[0066] Of course, in other embodiments, multiple liquid storage containers 10 can also be lifted 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 be connected to the bottom of the cleaning tank 21. The mounting plate 70 is provided with an avoidance hole 71 for avoiding predetermined components. It can be understood that the mounting plate 70 avoids the predetermined components through the avoidance hole 71, so that the bottom of the inner cavity 11 of the liquid storage container 10 can be connected to the bottom of the cleaning tank 21, so as to facilitate efficient transmission of the cleaning material, and at the same time, the mounting plate 70 can stably support the liquid storage container 10 to ensure the stability of the liquid storage container 10.

[0068] Exemplarily, the avoidance hole 71 can be used to avoid the fixed column protruding from the bottom of the liquid storage container 10, and the pipe joint can respectively connect the fixed column and the transmission pipe, 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 column, the hollow part of the pipe joint and the transmission pipe.

[0069] Illustratively, there may be one or more avoidance holes 71 .

[0070] like Figure 2 As shown, in an optional embodiment, the first control valve includes a plurality of solenoid valves, and the plurality of solenoid valves correspond one-to-one to the plurality of liquid storage containers 10 , and 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] Exemplarily, the solenoid valve is disposed on a transmission tube connecting 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 tube.

[0072] like Figure 7 and Figure 8 As shown, in some embodiments, the inner cavities 11 of the plurality of liquid storage containers 10 are connected to the cleaning tank 21 through a transmission tube 200 respectively. The first control valve includes a fixed part 31, a plurality of movable parts 32 and an electromagnet 33. The plurality of movable parts 32 are respectively connected to the fixed part 31 through an elastic part 34, and any transmission tube is arranged between the fixed part 31 and a movable part 32. The movable part 32 can clamp the transmission tube with the fixed part 31 under the action of the elastic part 34, and control the corresponding inner cavity 11 and the cleaning tank 21 to disconnect. The electromagnet 33 is located on the side of the movable part 32 away from the fixed part 31 and is connected to the fixed part 31. The electromagnet 33 is used to energize to provide an adsorption force to the corresponding movable part 32 away from the fixed part 31, loosen the transmission tube between the movable part 32 and the fixed part 31, and control the corresponding inner cavity 11 and the cleaning tank 21 to be connected. It can be understood that the first control valve is a normally closed control valve, and the movable member 32 and the fixed member 31 maintain a state of clamping the transmission tube under the action of the elastic member 34, that is, the inner cavity 11 is kept disconnected from the cleaning tank 21.

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

[0074] For example, Figure 7 As shown, the movable part 32 is connected to the fixed part 31 through four elastic parts 34. The four elastic parts 34 are evenly distributed on both sides of the transmission tube in pairs, and the two elastic parts 34 on the same side are arranged at intervals so that the movable part 32 is evenly stressed and the transmission tube is stably clamped to ensure that the inner cavity 11 and the cleaning tank 21 connected to the transmission tube are disconnected.

[0075] Exemplarily, the movable part 32 is a magnetic part, such as a silicon steel sheet, a ferrite, etc. When the cleaning material in the inner cavity 11 needs to be transferred to the cleaning tank 21 through the corresponding transfer pipe, the electromagnet 33 can be energized to generate an electromagnetic force, and the movable part 32 resists the elastic force of the elastic part 34 under the adsorption of the electromagnetic force, approaches the electromagnet 33 and moves away from the fixed part 31, and the transfer pipe between the movable part 32 and the fixed part 31 is loosened, so that the transfer pipe realizes the communication between the corresponding inner cavity 11 and the cleaning tank 21, so that the cleaning material in the inner cavity 11 can be transferred to the cleaning tank 21. When the preset conditions are met, the electromagnet 33 can be stopped from being energized, and the movable part 32 approaches the fixed part 31 under the elastic force of the elastic part 34, and re-clamps the transfer pipe with the fixed part 31, and controls the corresponding inner cavity 11 and the cleaning tank 21 to be disconnected.

[0076] like Figure 8 As shown, in an optional embodiment, there are multiple electromagnets 33, and the multiple electromagnets 33 are arranged one by one corresponding to the multiple movable parts 32. By energizing one of the multiple electromagnets 33, the electromagnet 33 provides an adsorption force to the corresponding movable part 32 away from the fixed part 31, thereby controlling the movable part 32 to be away from the fixed part 31, so that the transmission pipe between the movable part 32 and the fixed part 31 is connected to 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 fixing member 31, and the electromagnet 33 can move relative to the fixing member 31 to correspond to different movable members 32. By providing one electromagnet 33 movably connected to the fixing member 31, so that the electromagnet 33 controls the movement of one movable member 32 corresponding to its position, it is beneficial to ensure that at the same time, only one of the multiple liquid storage containers 10 has its inner cavity 11 connected to the cleaning tank 21, and the inner cavities 11 of the other liquid storage containers 10 are disconnected from the cleaning tank 21.

[0078] Exemplarily, the cleaning device also includes a shell 50, the electromagnet 33 can be movably connected to the bottom plate, the fixing part 31 is spaced apart on the side of the electromagnet 33 away from the bottom plate and is connected to the bottom plate of the shell 50 through the fixing plate, and a plurality of movable parts 32 are located between the electromagnet 33 and the fixing part 31, and are respectively connected to the fixing part 31 through elastic parts 34.

[0079] Exemplarily, multiple movable parts 32 are arranged at intervals along the length direction of the fixed part 31, and the electromagnet 33 is slidably connected to the bottom plate to slide along the length direction of the fixed part 31 relative to the fixed part 31. The electromagnet 33 can slide to correspond to one of the multiple movable parts 32 to achieve adsorption of the movable part 32 and connect the corresponding inner cavity 11 and the cleaning tank 21.

[0080] Exemplarily, the electromagnet 33 is slidably connected to the base plate via a screw-nut transmission assembly.

[0081] Furthermore, the first control valve 30 also includes a conductive member 35 for conducting electricity. The electromagnet 33 is provided with an electrical connector 331 . The electromagnet 33 can drive the electrical connector 331 to slide. The electromagnet 33 is in contact with and communicates with the conductive member 35 via the electrical connector 331 .

[0082] Furthermore, there are multiple conductive members 35, and the multiple conductive members 35 are arranged at intervals along the sliding direction of the electromagnet 33. When the electromagnet 33 slides to correspond to different movable members 32, the electromagnet 33 can contact and communicate with one of the multiple conductive members 35, and when the electromagnet 33 slides to another movable member 32 and staggers with the currently corresponding movable member 32, the electromagnet 33 is disconnected from the conductive member 35, ensuring that the electromagnet 33 remains in a power-off state at this time, so as to prevent the electromagnet 33 from generating adsorption force on two movable members 32 at the same time, thereby causing the two transmission pipes to leak cleaning materials.

[0083] In some embodiments, the liquid control device 30 includes a second control valve and a plurality of bidirectional pumps, each of which is connected to an inner cavity 11 and a cleaning tank 21, so that the bidirectional pump can control the cleaning material in the inner cavity 11 to be transferred to the cleaning tank 21, or control the cleaning material in the cleaning tank 21 to be transferred to the inner cavity 11. The second control valve can control one of the inner cavities 11 of the cleaning tank 21 to be connected or disconnected with the bidirectional pump. It can be understood that the bidirectional pump can realize the supply of the cleaning material in the inner cavity 11 to the cleaning tank 21, and the reflux of the cleaning material in the cleaning tank 21 to the inner cavity 11.

[0084] For example, for ease of understanding, the second control valve is used to control the connection or disconnection between the cleaning tank and the two-way pump. When the object to be cleaned needs to be cleaned, one of the multiple two-way pumps can be controlled by the second control valve to be connected to the cleaning tank 21, while the other two-way pumps are disconnected from the cleaning tank 21. The two-way pump connected to the cleaning tank 21 is started so that the cleaning material in the inner cavity 11 connected to the two-way pump can be transferred to the cleaning tank 21. After the preset conditions are met, the two-way pump is controlled by the second control valve to be disconnected from the cleaning tank 21, and the two-way pump stops transmitting, so as to use the cleaning material in the cleaning tank 21 to clean the object to be cleaned. After one cleaning is completed, the same two-way pump can be controlled by the second control valve to be connected to the cleaning tank 21 again, and the two-way pump can be started to transfer the cleaning material in the cleaning tank 21 back to the original inner cavity 11, so as to realize the reflux of the cleaning material. After the recovery is completed, another one of the multiple two-way pumps can be controlled by the second control valve to be connected to the cleaning tank 21, and the two-way pump can be started to transfer the cleaning material in the inner cavity 11 of another liquid storage container 10 to the cleaning tank 21 to achieve secondary cleaning of the object to be cleaned.

[0085] Specifically, the structure of the second control valve may refer to the first control valve described above, and will not be described in detail here.

[0086] In some embodiments, the cleaning device further includes a recovery mechanism, and the recovery mechanism is used to recover the cleaning material in the cleaning tank 21 to the corresponding inner cavity 11.

[0087] In an exemplary embodiment, the liquid storage container 10 includes a first liquid storage container 10 and a second liquid storage container 10. The cleaning material in the inner cavity 11 of the first liquid storage container 10 is transferred to the cleaning tank 21. After the cleaning material in the cleaning tank 21 is used to clean the object to be cleaned, the cleaning material in the cleaning tank 21 can be recovered into the inner cavity 11 of the first liquid storage container 10 through a recovery 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 the cleaning material in the cleaning tank 21 is used to clean the object to be cleaned, the cleaning material in the cleaning tank 21 can be recovered into the inner cavity 11 of the second liquid storage container 10 through a recovery 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. The cleaning material in the inner cavity 11 of the first liquid storage container 10 is transferred to the cleaning tank 21. After the cleaning material in the cleaning tank 21 is used to clean the object to be cleaned, 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 the cleaning material in the cleaning tank 21 is used to clean the object to be cleaned, the cleaning material in the cleaning tank 21 can be recovered into the inner cavity 11 of the first liquid storage container 10 through the recovery mechanism.

[0089] Optionally, the recycling mechanism may process the recycled cleaning material and then recycle it into the corresponding inner cavity 11, or may directly recycle the recycled cleaning material into the corresponding inner cavity 11, which is not specifically limited here.

[0090] Exemplarily, the recovery mechanism includes the above-mentioned lifting assembly 40 , and the lifting assembly 40 drives the liquid storage container 10 or the tank body 20 to rise and fall, so as to recover the cleaning material in the cleaning tank 21 to the corresponding inner cavity 11 .

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

[0092] Exemplarily, the cleaning tank 21 has a third opening, which is located at the bottom of the cleaning tank 21. The recovery mechanism can be connected to 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 recovered into the corresponding inner cavity 11 through the recovery mechanism.

[0093] In some embodiments, the cleaning device further includes a liquid level sensor 80 , which is disposed in the tank body 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] Illustratively, after the liquid control device 30 controls the inner cavity 11 of one of the multiple liquid storage containers 10 to be connected to the cleaning tank 21, the cleaning material in the inner cavity 11 is transferred to the cleaning tank 21, and 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 be used to control the inner cavity 11 to be disconnected from the cleaning tank 21, and the transfer of cleaning materials into the cleaning tank 21 can be stopped.

[0095] Exemplarily, the liquid level sensor 80 includes a photoelectric liquid level sensor or an ultrasonic liquid level sensor.

[0096] In an optional embodiment, the cleaning device also includes an oscillator 90, which can be arranged in the shell 50, and the tank body 20 is arranged in the oscillator 90. The oscillator 90 is used to drive the tank body 20 and the cleaning material in the cleaning tank 21 to oscillate, so that the cleaning material in the cleaning tank 21 flows, thereby improving 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, Figure 3 As shown, a card slot 91 is provided at the top of the oscillator 90, and a card block 22 is formed at the bottom of the slot body 20. The card block 22 and the card slot 91 are engaged with each other to ensure the connection stability between the slot body 20 and the oscillator 90.

[0099] Exemplarily, the block 22 is provided with a guide hole 23, one end of the guide hole 23 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 an avoidance groove 92 connected to the card slot 91, and the card slot 91 is located on one side of the avoidance groove 92 in the horizontal direction, for avoiding the opening of the guide hole 23.

[0100] Exemplarily, a fixing column extending in the horizontal direction is protruding from the outer surface of the block 22, and the hollow portion of the fixing column constitutes a part of the guide hole 23. The pipe joint can connect the fixing column 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 via the transmission pipe, the hollow portion 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 in the cleaning tank 21. The agitator is used to stir the cleaning material in the cleaning tank 21 to make the cleaning material in the cleaning tank 21 flow, thereby improving the cleaning efficiency of the object to be cleaned.

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

[0103] Furthermore, the tank body 20 is provided with a mounting groove connected to the cleaning tank 21, the mounting groove is located at the bottom of the cleaning tank 21, the magnetic stirrer is located in the mounting groove, and the stirrer body is located below the tank body 20 and is arranged corresponding to the magnetic stirrer.

[0104] In another optional embodiment, the cleaning device 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 an upper cover 100, which is detachably connected to the tank body 20, and is used to cover or expose the notch of the cleaning tank 21. It can be understood that the object to be cleaned can be placed in the cleaning tank 21 through the notch of the cleaning tank 21. When the object to be cleaned is cleaned, the notch of the cleaning tank 21 can be covered by the upper cover 100 to prevent the cleaning material in the cleaning tank 21 from splashing or volatilizing.

[0106] Exemplarily, the upper cover 100 and the tank body 20 are sealed and connected via a seal.

[0107] Exemplarily, the liquid level sensor 80 may be disposed on the upper cover 100 .

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

[0109] The embodiment of the present 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 printing sample; the cleaning device includes a plurality of liquid storage containers, a tank body, and a liquid control device, the plurality of liquid storage containers are all provided with an inner cavity, and the plurality of 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, controlling the liquid control device to connect a 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] Exemplarily, the liquid control device includes a first control valve, the first control valve includes a plurality of solenoid valves, the plurality of solenoid valves correspond to the plurality of liquid storage containers one by one, and the cleaning tank and the inner cavity of the first liquid storage container are connected by controlling the solenoid valve corresponding to the first liquid storage container to open. Alternatively, the first control valve includes a fixed part, a movable part, and an electromagnet as described above, and the cleaning tank and the inner cavity of the first liquid storage container are connected through the transmission tube by controlling the electromagnet to absorb the movable part corresponding to the transmission tube connected to the first liquid storage container.

[0112] S102. When a preset condition is 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] Exemplarily, 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 also includes a liquid level sensor, which is arranged in the tank body. 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 the 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 and the cleaning tank are disconnected, and the transmission of cleaning material into the cleaning tank is stopped.

[0115] Exemplarily, the object to be cleaned can be immersed in the cleaning material in the cleaning tank for a preset time, and / or, the tank body and the cleaning material in the cleaning tank can be vibrated by an oscillator, and / or, the cleaning material in the cleaning tank can be stirred by an agitator, and / or, sound waves can be generated by an ultrasonic generator to vibrate the cleaning material in the cleaning tank, so that the cleaning material in the cleaning tank can clean the object to be cleaned.

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

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

[0118] S105. When a preset condition is 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] For step S104 and step S105 , reference may be made to the description of step S101 and step S102 , which will not be described in detail herein.

[0120] It is worth noting that the number of times the object to be cleaned is cleaned can be less than or equal to the number of liquid storage containers in the cleaning device, and the cleaning materials in the inner cavities of at least two of the multiple liquid storage containers can be used to clean the object to be cleaned in sequence, that is, the number of times the object to be cleaned is cleaned can be adjusted according to actual conditions. Exemplarily, the cleaning device includes 5 liquid storage containers, and the 5 liquid storage containers can be respectively filled with water of different purities, and the water in 2 or 4 of the liquid storage containers can be used in sequence to clean the object to be cleaned in the cleaning tank.

[0121] It is understandable that the cleaning method can sequentially use the cleaning materials in the inner cavities of at least two of the multiple liquid storage containers to clean the object to be cleaned, thereby achieving multiple cleaning of the object to be cleaned. The cleaning materials in the inner cavity of the liquid storage container are all transferred to a cleaning tank, and the object to be cleaned can be cleaned multiple times using a cleaning tank, thereby reducing the number of tank bodies and saving the space required for the tank bodies. At the same time, the object to be cleaned can always be located in the same cleaning tank, and the object to be cleaned does not need to be connected to a driving mechanism, which not only simplifies the installation of the object to be cleaned, but also saves the space occupied by the driving mechanism, reduces the volume of the cleaning device as a whole, and realizes a miniaturized design of the cleaning device.

[0122] In some embodiments, the cleaning material in the inner cavity of the target liquid storage container can be transferred to the cleaning tank through the first opening under the action of gravity, so as to save energy consumption of the cleaning device.

[0123] Further, the liquid control device includes a first control valve, which can control the connection or disconnection between the cleaning tank and the multiple inner cavities. The cleaning device also includes a lifting assembly, which is transmission-connected to the multiple liquid storage containers. The cleaning method also includes: controlling the lifting assembly to drive the liquid storage container to rise, so that the cleaning material in the inner cavity of the liquid storage container can be transferred to the cleaning tank under the action of gravity. Controlling the discharge of the cleaning material in the cleaning tank includes: controlling the lifting assembly to drive the liquid storage container to descend, so that the cleaning material in the cleaning tank can be transferred to the inner cavity of the liquid storage container under the action of gravity; controlling the first control valve to connect the inner cavity of the target liquid storage container and the cleaning tank, so that the cleaning material in the cleaning tank is transferred to the inner cavity of the liquid storage container under the action of gravity.

[0124] It can be understood that the lifting component drives the liquid storage container to rise and fall, and adjusts the relative position between the liquid storage container and the tank body, so that the cleaning material in the inner cavity of the liquid storage container is supplied to the cleaning tank of the tank body 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] Exemplarily, before executing step S101, the lifting assembly is controlled to drive the first liquid storage container to rise, so that when the first control valve is controlled to connect 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 the action of gravity. When executing step S103, the lifting assembly is controlled to drive the first liquid storage container to descend, so that when the first control valve is controlled to connect 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 the action of gravity. Before executing step S104, the lifting assembly is controlled to drive the second liquid storage container to rise, so that when the first control valve is controlled to connect the cleaning tank and the inner cavity of 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 the action of gravity.

[0126] In some embodiments, the cleaning device further comprises a drain pipe and a clamp valve, wherein the drain pipe is connected to the drain port at the bottom of the cleaning tank and the waste liquid barrel. When the cleaning material in the inner cavity of the liquid 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 so that the cleaning tank and the waste liquid barrel are disconnected. When controlling the discharge of the cleaning material in the cleaning tank, the clamp valve releases the drain pipe so that the cleaning tank and the waste liquid barrel are connected, and the waste liquid barrel can be located below the cleaning tank, so that the cleaning material in the cleaning tank is transferred to the waste liquid barrel under the action of gravity.

For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronic devices, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules.
