It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically limited. All directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0043] In order to make the description of the disclosed content more detailed and complete, the following is an illustrative description of the implementation methods and specific embodiments of the present application; however, this is not the only form of implementing or using the specific embodiments of the present application. The implementation methods cover the features of multiple specific embodiments and the method steps and sequences used to construct and operate these specific embodiments. However, other specific embodiments can also be used to achieve the same or equivalent functions and step sequences.

[0044] Please refer to Figure 1-Figure 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 prior art, the present application embodiment provides a drying device, a consumable box and a 3D printer. Please refer to Figure 1, is a structural schematic diagram of a drying device provided in an embodiment of the present application, the drying device includes a frame 10, a heating component 30 and an air blowing 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, the heating component 30 is arranged in the heating chamber 20, the gas is blown into the heating chamber 20 from the air inlet 11 through the air blowing component 40, and the blown gas is heated by the heating component 30 arranged in the heating chamber 20, so as to realize the gas being 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.

[0045] 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 providing 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 provided in the heating chamber 20 dries the gas, and the heated gas will be discharged from the first air outlet 121 provided 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.

[0046] As an optional embodiment, the heating component 30 provided in the present application can be arranged 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 arrange the heating component 30 on the side of the heating chamber 20 near the first air outlet 121 to avoid the excessive 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.

[0047] Of course, it is also feasible to arrange the heating component 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 gas blown out from the first air outlet 121 passes through the heating component 30 arranged outside the frame 10, and the gas blown out can also be heated. The gas that starts to rise after being heated can also achieve the effect of drying the consumables.

[0048] Obviously, whether the heating component 30 is set on a side of the frame 10 close to the first air outlet 121 or on a side of the frame 10 close to the first air outlet 121, the consumables can be dried. Therefore, the present 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.

[0049] Please refer to Figure 5 , a schematic diagram of the structure of the heating component 30 in the drying device provided in an embodiment of the present application, the present application preferably arranges 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, and the following explanation of the present application will continue to be described based on the arrangement of the heating component 30 in the heating chamber 20, but this does not serve as a limitation on the specific arrangement position of the heating component 30 of the present application, and those skilled in the art should be aware of this.

[0050] 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 further provided in the frame 10. Figure 6 , which is a structural schematic diagram of the air inlet extension channel 41 in the drying device provided in an embodiment of the present application. It can be observed that a heating chamber 20 and a drying chamber 22 which are interconnected are arranged in the frame 10, wherein the heating chamber 20 is connected to the air blowing assembly 40. In the present application, the heating assembly 30 is arranged in the heating chamber 20 and is connected to the air blowing assembly 40 arranged on the frame 10. Since the heating assembly 30 is arranged in the heating chamber 20, the gas blown into the air blowing assembly 40 arranged outside the frame 10 can be dried.

[0051] Please continue to refer to Figure 5 In the present application, the heating component 30 is arranged in the heating chamber 20, the air inlet 11 is arranged on the side of the heating chamber 20 close to the blowing component 40, and a second wall 23 is arranged between the heating chamber 20 and the drying chamber 22. Preferably, the first wall 21 is arranged above the second wall 23 in the direction of gravity, and the second air outlet 122 is arranged 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.

[0052] 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.

[0053] As an optional implementation, please refer to Figure 3 , 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 further 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 released 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.

[0054] 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 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 desiccant bag. At this time, the blowing direction of the blowing assembly 40 will not affect the desiccant material filled in the drying chamber 22.

[0055] Please refer to Figure 4 , is a schematic structural 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 gravity direction gradually decreases in the direction away from the second wall 23.

[0056] It should be noted that the present application sets the third wall 24 as an arc 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 released 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 travel, due to its proximity to the second wall 23, has a longer travel 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. At this time, the fully dried gas can also be released from the third air outlet 123.

[0057] 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.

[0058] Furthermore, the gas heated by 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 it 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.

[0059] 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.

[0060] In another specific embodiment provided in the present application, the above-mentioned blowing assembly 40 can be set in the form of other exhaust equipment such as a fan and an exhaust pump. As long as it can suck external air into the heating chamber 20 for drying, any form of the blowing assembly 40 selected is feasible, and the present application does not impose further restrictions on this; considering that the shapes and volumes of different blowing assemblies 40 may not be convenient for direct connection 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 blowing assembly 40, and sets the blowing assembly 40 above the heating chamber 20 through the frame 10, and connects with the air inlet 11 through the air inlet extension channel 41, thereby realizing communication with the heating assembly 30 arranged 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.

[0061] Since the number of material trays 70 used in the actual 3D printing process is more than one, it is necessary to meet the requirement of storing several material trays 70 at the same time. Figure 1 , which can accommodate four material trays 70 at the same time. In the present 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, blowing components 40, heating chamber 20 and drying chamber 22, and two sets of heating components 30, blowing components 40, heating chamber 20 and drying chamber 22 are arranged corresponding to the four material trays 70.

[0062] Of course, if costs permit, each material tray 70 may be provided with a corresponding heating component 30, blowing component 40, heating chamber 20 and drying chamber 22, or three material trays 70 or four material trays 70 may be provided in a group. The above arrangements are all feasible as long as it is possible to dry several installed material trays 70. Any improvements made under the premise of cost permitting are all feasible.

[0063] It should be noted that since several material trays 70 will be arranged in an adjacent manner 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, the present application does not impose further restrictions on the specific positions of the consumables and the specific numbers of the corresponding heating components 30, blowing components 40, heating chambers 20 and drying chambers 22.

[0064] 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 a plurality of 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.

[0065] Specifically, the housing 50 includes a base 51 and a cover 52 disposed on the base 51. Figure 8 , is a structural schematic diagram of the display panel 56 in the drying device provided in an embodiment of the present application. It can be observed that the cover body 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 body 52 can also be achieved through other mechanical structures, and the present application does not impose further restrictions on this.

[0066] 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, and 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.

[0067] Please continue to refer to Figure 2 In the present application, the frame 10 is arranged on one side of the shell 50 to form a cavity for accommodating the above-mentioned drying device with a side wall of the shell 50. A clamping assembly 60 is arranged at the pressing position between the inner wall of the top of the shell 50 and the material tray 70. The clamping assembly 60 is arranged 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 of materials.

[0068] 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 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 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 deformation according to the size and The rotation condition is adaptively adjusted. The present application presses the arc-shaped pressing member 61 above the material tray 70, so that pre-pressure can be provided to the material tray 70 to increase the friction after the cover body 52 is pressed. Not only can the consumables be pre-pressed during the drying process, so that the temperature of the consumable material tray wrapped with the consumables increases under the influence of the rising hot air, and the temperature of the moisture in the consumables increases under the influence of the rising hot air, thereby reducing the water content of the consumables and shortening the drying time, but also the material tray 70 can be prevented from slipping during the process of feeding and retracting the material, thereby affecting the 3D printing effect.

[0069] In the embodiment of the present application, the clamping component 60 is set as an arc-shaped clamping member 61 that is compatible with the outer edge of the material tray 70. It can not only pre-compress the consumables during the drying process, so that the temperature of the material tray 70 wrapped with the consumables increases 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 clamping member 61. After the dry hot air rises, the water molecules absorbed into the air become 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, and the humid gas inside the shell 50 is simultaneously dried through the several drying paths exemplified above, thereby further improving the drying effect.

[0070] In the embodiments of this application, please continue to refer to Figure 3 It can be observed that a transmission roller 53 and a follower transmission roller 54 arranged parallel to the transmission roller are rotatably installed on the inner side wall of the base 51, so that a plurality of 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 a plurality of material trays 70 below the clamping assembly 60 and above the heating assembly 30, and further dries the consumables wound 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 process of feeding and retracting the material. 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, so as to avoid the normal rotation of the material tray 70 being affected by the close distance.

[0071] For further information, please refer to Figure 7 , is a schematic diagram of the structure of the strip-shaped snap-in groove 55 in the drying device provided in an embodiment of the present application. The present application further provides a plurality of strip-shaped snap-in grooves 55 on the bottom inner side 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 snap-in standards are used, the material trays 70 may move left and right during the process of feeding and withdrawing materials. Therefore, the present application further provides a plurality of strip-shaped snap-in grooves 55 on the bottom inner side wall of the shell 50. By snapping the outer edge of the material tray 70 with the corresponding strip-shaped snap-in grooves 55, material trays 70 of different sizes can be accommodated in the consumable box. The cooperation between the strip-shaped snap-in grooves 55 and the top clamping assembly 60 can prevent the material tray 70 from slipping or moving left and right during the process of feeding and withdrawing consumables.

[0072] When several material trays 70 are arranged inside the shell 50, corresponding drive rollers 53 and follower drive rollers 54 need to be set at the bottom of each material tray 70, or several material trays 70 can share the same set of drive rollers 53 and follower drive rollers 54. The above methods are all feasible and the present application does not impose further restrictions on this.

[0073] For further information, please refer to Fig. 9 , which is a structural schematic diagram of a power interface 57 in a 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 components inside the shell 50.

[0074] 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 material 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 clamping groove 55 and the top clamping assembly 60 can prevent the consumable tray 70 from slipping or moving left and right during the feeding and retracting process, thereby improving the quality of the finished product of 3D printing.

[0075] 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.

[0076] Compared with the prior art, the drying device, consumable box and 3D printer provided in the embodiments of the present application accelerate the convection of gas in the shell by arranging a heating component, a blast component and a heating chamber in the shell. The dried hot air 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, a pre-pressure is provided to the material tray to increase the friction force, so that the consumable tray wrapped with consumables increases in temperature under the influence of the 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 process of feeding and withdrawing the materials; a plurality of strip-shaped clamping grooves are arranged to enable the consumable box to adapt to material trays of different sizes, thereby preventing the material tray from moving left and right during the process of feeding and withdrawing the materials, and ensuring the quality of 3D printing.
