[0034] In existing technologies, most cleaning equipment for 3D printed dental models uses ultrasonic cleaning followed by ultraviolet curing. However, during the actual cleaning process, impurities are constantly generated on the inner wall of the cleaning cavity, affecting the cleaning effect of the model.

[0035] This utility model proposes an ultrasonic cleaning box structure.

[0036] Please see Figs. 1 to 3 In one embodiment of this utility model, the ultrasonic cleaning box structure includes: an ultrasonic transducer 100 and a housing 200, wherein the ultrasonic transducer 100 is used to generate mechanical vibration; the housing 200 forms a cleaning chamber, which includes a first chamber 300, a second chamber 400 and a third chamber 500 arranged sequentially from top to bottom, the second chamber 400 being connected to the first chamber 300 and the third chamber 500 respectively, the inner wall of the first chamber 300 being provided with a flow guiding slope 310, the flow guiding slope 310 being provided with a first end 320 and a second end 330, the second end 330 being disposed close to the second chamber 400, the extension direction of the flow guiding slope 310 from the first end 320 to the second end 330 being inclined toward the direction close to the second chamber 400, and the ultrasonic transducer 100 being fixedly connected to the housing 200 and disposed correspondingly to the flow guiding slope 310.

[0037] In this embodiment, it should be noted that ultrasonic cleaning is achieved by generating mechanical vibration through ultrasonic transducers 100. The number of ultrasonic transducers 100 can be one or more, selected according to actual needs, and fixedly installed on the outside of the housing 200 as required. The cleaning chamber is used to hold the cleaning liquid, which can be water, a cleaning agent, or a mixture of both. This embodiment is not limited, and the cleaning chamber can be of any shape, which is also not limited in this embodiment. After printing, the product is placed in the cleaning chamber to achieve ultrasonic cleaning, causing impurities or attached printing material carried by the product to fall into the cleaning liquid, thereby cleaning the product.

[0038] In practice, the first chamber 300 and the third chamber 500 are connected by a second chamber 400, which is located between the first chamber 300 and the third chamber 500, and all three are filled with cleaning fluid. The shell 200 is integrally formed or comprises multiple sheet-like structures welded together to ensure the sealing of the cleaning chamber and prevent leakage.

[0039] The housing 200 is at least partially inclined, thus forming an inclined guide slope 310 in the first chamber 300. An ultrasonic transducer 100 is mounted on the corresponding portion of the housing 200. The inclined guide slope 310 and the mounting position of the ultrasonic transducer 100 allow impurities after cleaning to fall along the guide slope 310 into the second chamber 400, and then into the third chamber 500, preventing impurities from affecting the cleaning effect and facilitating cleaning. The first end 320 and the second end 330 of the guide slope 310 are positioned opposite each other. The second end 330 is close to the second chamber 400 and connected to an inner wall of the second chamber 400, while the first end 320 is positioned away from the second end 330. In the vertical direction, the height of the first end 320 is greater than the height of the second end 330, thus making the guide slope 310 inclined and facilitating the movement of impurities along the guide slope 310 into the second chamber 400.

[0040] This utility model's technical solution uses a shell 200 to form a cleaning chamber, which includes a first chamber 300, a second chamber 400, and a third chamber 500 that are interconnected. These three chambers are arranged vertically from top to bottom. The first chamber 300 is provided with a guide slope 310, which extends from the second end 330 of the first end 320 towards the direction close to the second chamber 400. In this way, during the cleaning process, the impurities washed away sink to the guide slope 310 and fall into the second chamber 400 along the guide slope 310. They then fall into the third chamber 500 through the second chamber 400 and are discharged through the third chamber 500. The inclined surface 310 prevents the accumulation of cleaning debris and the growth of dirt. Furthermore, the ultrasonic transducer 100 is installed in the housing 200 and corresponds to the inclined surface 310, which further promotes the movement of debris along the inclined surface 310 and away from the inclined surface 310, avoiding the accumulation of debris in the first chamber 300 and affecting cleaning, thus greatly improving the cleaning effect.

[0041] refer to Fig. 2 As shown, in one embodiment, the ultrasonic cleaning box structure further includes a mounting frame 600, with both ends of the mounting frame 600 fixedly connected to the housing 200. The mounting frame 600 is used to mount a basket, which is located inside the first chamber 300 and is used to place the product to be cleaned.

[0042] In practice, the mounting bracket 600 is located within the first chamber 300. Both ends of the mounting bracket 600 are fixedly connected to the housing 200. To ensure the airtightness of the first chamber 300, the mounting bracket 600 is welded to the housing 200. The basket is used to hold the product to be cleaned. The mounting bracket 600 spans across the first chamber 300. The mounting bracket 600 and / or the housing 200 fixably support the edge of the basket. Understandably, the edge of the basket can be bent, and the bent portion is supported by the housing 200 and the support bracket, allowing most of the basket and the product to be immersed in the cleaning liquid in the first chamber 300, ensuring the cleaning effect of the product.

[0043] Furthermore, the mounting bracket 600 has a first mounting hole 610, and the housing 200 has a second mounting hole 210. The first mounting hole 610 and the second mounting hole 210 are respectively used to mount the basket. In a specific implementation, the first mounting hole 610 is located near the center of the mounting bracket 600, and the second mounting hole 210 is located at the corresponding part of the housing 200. It can be understood that this part of the housing 200 also forms part of the inner wall of the first chamber 300. The first mounting hole 610 and the second mounting hole 210 are correspondingly arranged, and fixing blocks are respectively installed on them. The fixing blocks are used to support the basket. In addition, the basket can also be rotatably mounted within the first chamber 300 via the fixing blocks. During the cleaning process, the product can be shaken by the basket to improve the cleaning effect. In this case, the fixing block can be a rotating shaft.

[0044] Continue to refer to Fig. 2 As shown, in another embodiment, the first chamber 300 includes a first sub-chamber and a second sub-chamber that are interconnected. The first sub-chamber and the second sub-chamber are respectively located on both sides of the mounting frame 600. The housing 200 is provided with a support frame 220, which is used to support the basket.

[0045] In this embodiment, the mounting frame 600 divides the first chamber 300 into a first sub-chamber and a second sub-chamber. Correspondingly, the basket is provided with clearance space to avoid the mounting frame 600, ensuring that both the first and second sub-chambers contain products to be cleaned. It is understood that the basket is supported by the mounting frame 600 and the support frame 220. The support frame 220 extends circumferentially along the inner wall of the first chamber 300. The support frame 220 can be welded to the inner wall of the first chamber 300 or integrally formed with the housing 200 to improve the strength of the support frame 220 and simplify the construction process. In specific implementation, the edge of the housing 200 is bent to form the support frame 220.

[0046] The two embodiments described above can coexist. The appropriate and suitable basket can be selected according to actual needs to improve the applicability of the ultrasonic cleaning box structure.

[0047] refer to Fig. 3 As shown, in one embodiment, the ultrasonic cleaning box structure is further provided with a clearance groove 700, and the ultrasonic transducer 100 is disposed in the clearance groove 700. The clearance groove 700 includes a first inner wall 710, which is correspondingly disposed with the guide slope 310 and the ultrasonic transducer 100 is fixedly installed thereon.

[0048] In this embodiment, the clearance groove 700 facilitates the installation of the ultrasonic transducer 100. It is understood that the portion of the housing 200 corresponding to the guide slope 310 also forms a first inner wall 710, on which the ultrasonic transducer 100 is installed. The space of the clearance groove 700 ensures that the ultrasonic transducer 100 has sufficient installation space.

[0049] Furthermore, in one embodiment, the inner wall of the third chamber 500 is provided with a relief slope 510, the relief slope 510 includes a third end 520 and a fourth end 530, the third end 520 is disposed near the second chamber 400, and the extension direction of the relief slope 510 from the fourth end 530 to the third end 520 is inclined towards the direction near the second chamber 400. The relief groove 700 also includes a second inner wall 720, the second inner wall 720 is disposed corresponding to the relief slope 510.

[0050] In this embodiment, the third end 520 of the avoidance slope 510 is close to the second chamber 400, and the fourth end 530 is disposed opposite to the third end 520. The avoidance slope 510 is inclined in the direction of the line connecting the third end 520 and the fourth end 530. In the specific implementation, the height of the third end 520 is greater than the height of the fourth end 530. In this way, the avoidance slope 510 is inclined to prevent impurities falling from the second chamber 400 from staying on the avoidance slope 510. In addition, the arrangement of the avoidance slope 510 can also increase the volume of the third chamber 500.

[0051] Furthermore, in one embodiment, the clearance groove 700 further includes a third inner wall 730, which is vertically arranged and whose two ends are respectively connected to the first inner wall 710 and the second inner wall 720.

[0052] Specifically, the portion of the inner wall of the second chamber 400 formed by the shell 200 corresponds to the third inner wall 730 of the clearance groove 700. The third inner wall 730 is vertically arranged to ensure that the clearance groove 700 has a certain space. In addition, the length of the third inner wall 730 is relatively short to avoid affecting the falling of impurities.

[0053] In one embodiment, an outlet 540 is provided on the inner wall of the third chamber 500. In a specific implementation, the outlet 540 is located at the bottom of the third chamber 500 and is used to discharge cleaning liquid and impurities.

[0054] This utility model also proposes a 3D printing system, which includes an ultrasonic cleaning box structure. The specific structure of the ultrasonic cleaning box structure is as described in the above embodiments. Since this 3D printing system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
