DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] In the description of this application, the meaning of "plurality" is at least two, for example, two, three, etc., unless otherwise specifically defined. All directional indications in the embodiments of this application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement of the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0038] To provide a more detailed and complete description of the present disclosure, the following provides illustrative descriptions of the embodiments and examples of the present application; however, these descriptions are not intended to be the only ways to implement or use the embodiments of the present application. The embodiments cover features of various embodiments, as well as the method steps and sequences for constructing and operating these embodiments. However, other embodiments may also be used to achieve the same or equivalent functionality and step sequences.

[0039] Conventional methods for drying consumables primarily involve placing a desiccant in a confined space. The desiccant absorbs moisture from the air, reducing humidity and preventing the effects of damp air on printing consumables. However, this method takes a long time to dry and fails to accelerate the absorption of water vapor from the air, resulting in less than ideal results. Therefore, accelerating the absorption of water vapor from the air to achieve rapid drying of consumables remains an urgent issue.

[0040] Please refer to Figures 1 to 9. In order to solve the problem of how to accelerate the volatilization and absorption of water vapor in the air and achieve rapid drying of consumables in the related art, the embodiment of the present application provides a drying device, a consumable box and a 3D printer. Please refer to Figure 1, which is a structural schematic diagram of the drying device provided in the embodiment of the present application. The drying device includes a frame 10, a heating component 30 and a blast component 40, wherein the frame 10 includes an air inlet 11, an air outlet 12 and a heating chamber 20. The present application connects the above-mentioned air inlet 11 and the air outlet 12 through the heating chamber 20, and sets the heating component 30 in the heating chamber 20. The gas is blown into the heating chamber 20 from the air inlet 11 through the blast component 40, and the heating component 30 set in the heating chamber 20 heats the blown gas, thereby realizing that the gas is transported in the order of the above-mentioned air inlet 11, the heating chamber 20 and the air outlet 12, and the consumables stored in the frame 10 are dried.

[0041] Compared with the related art, the drying device, consumable box and 3D printer provided in the embodiments of the present application accelerate the convection of gas by setting a heating component 30, a blowing component 40 and a heating chamber 20. The hot air heated by the heating chamber 20 will rise, and the consumable material disk 70 wrapped with the consumables will increase in temperature under the influence of the rising hot air, causing the moisture in the consumables to evaporate, reducing the water content of the consumables, greatly shortening the drying time, and realizing rapid drying of the printing consumables.

[0042] In an embodiment of the present application, the air outlet 12 is provided with a first air outlet 121, a second air outlet 122 and a third air outlet 123, wherein the heating chamber 20 is provided with a first wall 21, and the first air outlet 121 is provided on the first wall 21. By setting the heating component 30 in the heating chamber 20, the humid gas is blown into the heating chamber 20 from the air inlet 11 by the blowing component 40, and the heating component 30 set in the heating chamber 20 dries the gas. The heated gas will be discharged from the first air outlet 121 set on the first wall 21. At this time, the gas will be transported and dried in the order of the air inlet 11, the heating chamber 20 and the first air outlet 121.

[0043] As an optional embodiment, the heating component 30 provided in the present application can be set not only on the side of the heating chamber 20 near the first air outlet 121, but also on the side of the frame 10 near the first air outlet 121. Since the volume of the material tray 70 is usually large, when drying the consumables wrapped on the material tray 70, it is preferred to set the heating component 30 on the side of the heating chamber 20 near the first air outlet 121 to avoid the large volume of the heating component 30 affecting the self-rotation of the material tray 70. At this time, the heating of the humid air by the heating component 30 will also increase the temperature of the consumables, volatilize the moisture in the consumables, reduce the water content of the consumables, and achieve rapid drying of the consumables.

[0044] Of course, it is also feasible to dispose the heating assembly 30 outside the frame 10 near the first air outlet 121. This arrangement can also achieve the effect of drying the consumables. In this embodiment, the air blown out from the first air outlet 121 passes through the heating assembly 30 disposed outside the frame 10, and the air blown out can also be heated. The air that begins to rise after being heated can also achieve the effect of drying the consumables.

[0045] Obviously, whether the heating component 30 is set on the side of the frame 10 close to the first air outlet 121 or on the side of the frame 10 close to the first air outlet 121, the consumables can be dried. Therefore, this application does not impose further restrictions on the specific setting position of the heating component 30, as long as its setting position is capable of heating the gas blown into the blowing component 40.

[0046] Please refer to Figure 5, which is a structural diagram of the heating component 30 in the drying device provided in an embodiment of the present application. The present application preferably sets the heating component 30 on the side of the heating chamber 20 close to the first air outlet 121 to achieve heating of the blown-in gas. The following explanation of the present application will continue to be based on setting the heating component 30 in the heating chamber 20 for description, but this does not serve as a limitation on the specific setting position of the heating component 30 of the present application, and those skilled in the art should be aware of this.

[0047] As an optional embodiment, the humid gas may not be sufficiently heated in the heating chamber 20 due to factors such as quality and cannot be discharged from the first air outlet 121. Therefore, in the embodiment of the present application, a drying chamber 22 connected to the heating chamber 20 is also provided in the frame 10. Please refer to Figure 6, which is a structural diagram of the air inlet extension channel 41 in the drying device provided in the embodiment of the present application. It can be observed that the frame 10 is provided with a heating chamber 20 and a drying chamber 22 that are interconnected, wherein the heating chamber 20 is connected to the blower assembly 40. The present application sets the heating assembly 30 in the heating chamber 20 and connects it to the blower assembly 40 set on the frame 10. Since the heating assembly 30 is set in the heating chamber 20, the gas blown in by the blower assembly 40 set outside the frame 10 can be dried.

[0048] Please continue to refer to Figure 5. In this application, the heating component 30 is set in the heating chamber 20, the air inlet 11 is set on the side of the heating chamber 20 close to the blowing component 40, and a second wall 23 is set between the heating chamber 20 and the drying chamber 22. Preferably, the first wall 21 is set above the second wall 23 in the direction of gravity, and the second air outlet 122 is set on the second wall 23. At this time, the drying chamber 22 is connected to the heating chamber 20 through the second air outlet 122, so that the gas heated by the heating component 30 is blown from the second air outlet 122 into the drying chamber 22 for drying.

[0049] When the humid gas is not heated sufficiently in the heating chamber 20, resulting in the gas being unable to dissipate from the first air outlet 121, it will continue to enter the drying chamber 22 from the second air outlet 122 set on the second wall 23 under the action of the blowing assembly 40. At the same time, the drying chamber 22 provided in the present application is filled with a drying material for drying the humid gas, so the humid gas entering the drying chamber 22 will be dried under the action of the drying material.

[0050] As an optional embodiment, please refer to Figure 3, which is a structural schematic diagram of the first wall 21 in the drying device provided in an embodiment of the present application. The present application also provides a third wall 24 on the drying chamber 22, and the third air outlet 123 is provided on the third wall 24. The gas dried in the drying chamber 22 will be discharged from the third air outlet 123. At this time, the gas will be transported and dried in the order of the air inlet 11, the heating chamber 20, the second air outlet 122, the drying chamber 22, and the third air outlet 123.

[0051] It should be understood that the desiccant material filled in the drying chamber 22 of the present application refers to a substance that can remove moisture from the humid gas, such as commonly used chemical desiccants such as calcium sulfate and calcium chloride, which dry by combining with water to form hydrates, or commonly used physical desiccants such as silica gel and activated alumina, which dry by physically adsorbing water; as long as it can adsorb moisture from the humid gas entering the drying chamber 22, any selected desiccant material is feasible, and multiple desiccant materials can also be mixed for use. The present application does not further explain the specific setting form of the desiccant material; and the desiccant material can also be set in the form of a drying bag. At this time, the blowing direction of the blowing assembly 40 will not affect the desiccant material filled in the drying chamber 22.

[0052] Please refer to Figure 4, which is a structural schematic diagram of the third wall 24 in the drying device provided in an embodiment of the present application. It can be observed that the third wall 24 is an arc-shaped surface or an inclined surface, and the height of the third wall 24 in the direction of gravity gradually decreases in the direction away from the second wall 23.

[0053] It should be noted that the present application sets the third wall 24 as an arc-shaped surface or a sloped surface to reduce the space utilization rate of the drying device, and the farther the gas blown toward the drying chamber 22 through the second wall 23 is blown, the longer the distance it travels in the horizontal direction through the drying material in the drying chamber 22, thereby extending the contact distance between the gas and the drying material in the horizontal direction. When the gas is dried, it can also be dispersed from the third air outlet 123; on the contrary, the gas that is blown closer in the drying chamber 22 and has a shorter horizontal distance, due to its proximity to the second wall 23, has a longer distance in the direction of gravity than the gas that is blown farther in the horizontal direction, thereby extending the contact distance between the gas and the drying material in the direction of gravity. Therefore, it can also be effectively dried by the drying material, and the fully dried gas can also be dispersed from the third air outlet 123.

[0054] Please refer to Figure 2, which is a three-dimensional assembly diagram of the drying device provided in an embodiment of the present application. It can be observed that the material tray 70 provided in the present application is mounted above the drying chamber 22. Since the material tray 70 is mounted on the drying chamber 22, the present application preferably adapts the curvature or inclination of the first wall 21 and the third wall 24 to the edge device of the material tray 70 to avoid affecting the self-rotation of the material tray 70 during the feeding and withdrawing process.

[0055] Furthermore, the gas heated in the heating chamber 20 and dried in the drying chamber 22 will begin to rise after being heated and heated, and will become humid gas after absorbing water molecules in the air. It will sink due to factors such as temperature drop or weight increase, and then enter the heating chamber 20 and the drying chamber 22 for corresponding treatment under the action of the blowing component 40; of course, after the humid gas in the air sinks due to mass reasons, it can also directly enter the heating chamber 20 from the first air outlet 121, or directly enter the drying chamber 22 from the third air outlet 123 for drying, and can also be effectively dried by the heating component 20 and the drying material. At the same time, the heated and heated gas will also increase the temperature of the consumables, evaporate the moisture in the consumables, reduce the water content of the consumables, and achieve rapid drying of the consumables.

[0056] In a specific embodiment provided in the present application, the above-mentioned heating component 30 can be set to the form of a PCT (Positive Temperature Coefficient) heater. The PCT heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power-saving electric heater. The above-mentioned heating component 30 can also be set to the form of an electric heating wire or a heating film. As long as it can achieve heating of the gas, any heating component 30 selected is feasible, and the present application does not impose further restrictions on this.

[0057] In another specific embodiment provided in the present application, the above-mentioned blower assembly 40 can be set in the form of a fan, an air pump or other exhaust equipment. As long as it can suck external air into the heating chamber 20 for drying, any form of the blower assembly 40 selected is feasible, and the present application does not impose further restrictions on this; considering that the shape and volume of different blower assemblies 40 may not be convenient for direct communication with the heating chamber 20, the present application preferably sets the air inlet 11 on the side of the heating chamber 20 close to the blower assembly 40, and sets the blower assembly 40 above the heating chamber 20 through the frame 10, and connects it to the air inlet 11 through the air inlet extension channel 41, thereby realizing communication with the heating assembly 30 set in the heating chamber 20, so as to blow the humid gas from the air inlet extension channel 41 into the heating assembly 30 for drying.

[0058] Since more than one material tray 70 is used in the actual 3D printing process, it is necessary to meet the requirement of storing several material trays 70 at the same time. In a specific embodiment provided in this application, please continue to refer to Figure 1, four material trays 70 can be accommodated at the same time. In this application, the four material trays 70 are arranged in parallel. At the same time, in order to achieve simultaneous drying of the four material trays 70, it can be observed that every two material trays 70 share a set of heating components 30, air blast components 40, heating chamber 20 and drying chamber 22. Corresponding to the four material trays 70, two sets of heating components 30, air blast components 40, heating chamber 20 and drying chamber 22 are provided.

[0059] Of course, if the cost permits, each material tray 70 can be provided with a corresponding heating component 30, a blast component 40, a heating chamber 20 and a drying chamber 22, or three material trays 70 or four material trays 70 can be provided in a group. The above settings are all feasible, as long as it is possible to dry several material trays 70 that are installed. Any improvement made under the premise of cost permitting is feasible.

[0060] It should be noted that since several material trays 70 will be arranged in an adjacent arrangement when they are set, the corresponding heating components 30, blowing components 40, heating chambers 20 and drying chambers 22 also need to be arranged and set according to the positions of the material trays 70. Therefore, this application does not impose further restrictions on the specific positions of the consumables and the specific number of corresponding heating components 30, blowing components 40, heating chambers 20 and drying chambers 22.

[0061] Based on the above-mentioned drying device, the present application also provides a consumable box, which includes a shell 50 and the above-mentioned drying device. The present application uses the shell 50 to form a closed space, and sets up several material trays 70 inside the shell 50 to prevent external humid air from entering the consumable box and affecting the material trays 70 placed inside.

[0062] Specifically, the shell 50 includes a base 51 and a cover 52 provided on the base 51. Please refer to Figure 8, which is a structural diagram of the display panel 56 in the drying device provided in an embodiment of the present application. It can be seen that the cover 52 is hinged to the base 51 through hinges and hinge shafts. Of course, in actual applications, the connection between the base 51 and the cover 52 can also be achieved through other mechanical structures, and this application does not impose further restrictions on this.

[0063] As an optional embodiment, a sealing groove 511 is provided at the opening and closing position of the base 51 and the cover body 52 provided in the present application, and a sealing member 521 is provided at the position of the cover body 52 corresponding to the sealing groove 511. The external humid air is blocked outside the consumable box through the cooperation of the sealing member 521 and the sealing groove 511; in a specific embodiment provided in the present application, the above-mentioned sealing member 521 can be set in the form of a sealing rubber strip.

[0064] Please continue to refer to Figure 2. In this application, the frame 10 is set on one side of the interior of the shell 50, and forms a cavity for accommodating the above-mentioned drying device with one side wall of the shell 50. A clamping assembly 60 is set at the pressing position between the top inner wall of the shell 50 and the material tray 70. The clamping assembly 60 is set to press the outer edge of the material tray 70 to provide pre-pressure to the material tray 70 to prevent the material tray 70 from slipping during the drying and feeding and withdrawing processes.

[0065] Furthermore, the clamping assembly 60 provided in the present application includes an arc-shaped clamping member 61 adapted to the outer edge of the material tray 70, and a spring member 62 for floatingly mounting the clamping assembly 60 on the inner side wall of the cover body 52; it should be noted that the arc-shaped clamping member 61 does not press the material tray 70 to death inside the shell 50, but is floatingly mounted on the inner side wall of the cover body 52 through the spring member 62. The arc-shaped clamping member 61 is preferably set to a material that can undergo a certain deformation, such as plastic or rubber, so as to achieve a certain degree of deformation according to the size and The rotation situation is adaptively adjusted. The present application presses the arc-shaped pressing member 61 above the material tray 70, which can provide pre-pressure to the material tray 70 to increase the friction after the cover 52 is pressed. It can not only pre-press the consumables during the drying process, so that the consumable material tray wrapped with the consumables increases in temperature under the influence of rising hot air, and the moisture in the consumables increases in temperature under the influence of rising hot air, thereby reducing the water content of the consumables and shortening the drying time. It can also prevent the material tray 70 from slipping during the process of feeding and withdrawing the material, thereby affecting the 3D printing effect.

[0066] In an embodiment of the present application, the pressing component 60 is set to an arc-shaped pressing member 61 that is compatible with the outer edge of the material tray 70. It can not only pre-press the consumables during the drying process, so that the material tray 70 wrapped with the consumables increases in temperature under the influence of the rising hot air, but also enable the gas heated by the heating component 30 to rise along the arc-shaped guide of the arc-shaped pressing member 61. After the dry hot air rises, the water molecules absorbed into the air are converted into humid gas. The humid gas can directly enter the heating chamber 20 from the first air outlet 121, or directly enter the drying chamber 22 from the third air outlet 123 for drying, or the gas can be blown into the heating chamber 20 from the air inlet 11 through the blowing component 40, and the heating component 30 arranged in the heating chamber 20 heats the blown gas. The humid gas inside the shell 50 is simultaneously dried through the several drying paths in the above examples, further improving the drying effect.

[0067] In the embodiment of the present application, please continue to refer to Figure 3. It can be observed that the inner side wall of the base 51 is rotatably installed with a transmission roller 53 and a follower transmission roller 54 arranged parallel to the transmission rod, so that several material trays 70 are set between the transmission roller 53 and the follower transmission roller 54. The present application uses the transmission roller 53 and the follower transmission roller 54 to set several material trays 70 below the clamping assembly 60 and above the heating assembly 30, and further dries the consumables wrapped on the material tray 70 through the cooperation of the blast assembly 40, the heating assembly 30 and the heating chamber 20; at the same time, the material tray 70 can rotate between the transmission roller 53 and the follower transmission roller 54, and the setting of the clamping assembly 60 can also prevent the material tray 70 from slipping during the feeding and withdrawing process. The curvature and inclination of the first wall 21 and the third wall 24 are also adapted to the self-rotation direction of the material tray 70, to avoid the normal rotation of the material tray 70 being affected by the distance being too close.

[0068] Further, please refer to Figure 7, which is a structural schematic diagram of the strip-shaped positioning groove 55 in the drying device provided in an embodiment of the present application. The present application also provides a plurality of strip-shaped positioning grooves 55 on the bottom inner wall of the shell 50. Since the sizes of the material trays 70 used in actual applications may be different, if the same specification of the clamping standard is used, the material tray 70 may move left and right during the feeding and withdrawing process. Therefore, the present application also provides a plurality of strip-shaped positioning grooves 55 on the bottom inner wall of the shell 50. By clamping the outer edge of the material tray 70 with the corresponding strip-shaped positioning groove 55, material trays 70 of different sizes can be accommodated in the consumable box. The cooperation of the strip-shaped positioning groove 55 and the top clamping assembly 60 can prevent the material tray 70 from slipping or moving left and right during the feeding and withdrawing process of the consumables.

[0069] When several material trays 70 are arranged inside the shell 50, corresponding transmission rollers 53 and follower transmission rollers 54 need to be set at the bottom of each material tray 70. Alternatively, several material trays 70 can share the same set of transmission rollers 53 and follower transmission rollers 54. The above methods are all feasible and this application does not impose further restrictions on this.

[0070] Further, please refer to Figure 9, which is a structural schematic diagram of the power interface 57 in the drying device provided in an embodiment of the present application. The present application also provides a display panel 56 on the outer wall of the shell 50, and a temperature and humidity sensor for detecting the internal temperature and humidity is provided in the shell 50. The display panel 56 displays the working status of each electrical component in the shell 50 and the internal temperature and humidity of the shell 50 in real time. A power interface 57 for connecting to an external power supply and other standard interfaces 58 are also provided on the outer wall of the shell 50 to supply power to the devices inside the shell 50.

[0071] Based on the above-mentioned drying device, the present application also provides a 3D printer, including the consumable box provided by the above-mentioned embodiment. Since the consumables wrapped on the consumable tray 70 need to be applied during the 3D printing process, and the dryness of the consumables during the printing process needs to be ensured, the consumable box provided by the present application can be used on the basis of a conventional 3D printer to achieve rapid drying of the printing consumables used in the 3D printer. At the same time, the cooperation between the strip-shaped positioning groove 55 and the top clamping assembly 60 can prevent the consumables from slipping or moving left and right during the feeding and withdrawing process, thereby improving the quality of the finished product of 3D printing.

[0072] For other details about the above-mentioned consumable box and 3D printer to implement the above-mentioned technical solution, please refer to the description of the drying device provided in the above-mentioned application embodiment, which will not be repeated here.

[0073] Compared with the related art, the drying device, consumable box and 3D printer provided in the embodiments of the present application accelerate the convection of the gas in the shell by arranging a heating component, a blowing component and a heating chamber in the shell. The hot air dried inside the shell will rise, and the humid gas after absorbing water molecules in the air will descend into the heating chamber due to factors such as temperature drop or mass increase. The heating component arranged in the heating chamber and the desiccant filled in the drying chamber dry the humid gas, thereby accelerating the circulation and drying of the gas inside the shell and greatly shortening the drying time; a clamping component is arranged to press on the top of the material tray, and after the cover body is pressed, pre-pressure is provided to the material tray to increase friction, so that the consumable material tray wrapped with consumables increases in temperature under the influence of rising hot air, thereby reducing the water content of the consumables, realizing rapid drying of the printing consumables, and preventing the material tray from slipping during the feeding and withdrawing process; a number of strip-shaped clamping slots are arranged to enable the consumable box to adapt to material trays of different sizes, avoiding the material tray from moving left and right during the feeding and withdrawing process, thereby ensuring the quality of 3D printing.
