DETAILED DESCRIPTION

[0033] 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.

[0034] In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are intended only to explain the relative positional relationships and movement of the components in 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.

[0035] 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.

[0036] 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.

[0037] Please refer to Figures 1 to 7. 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 consumables 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, a heating component 20 and a blast component 30, wherein the frame includes an air outlet 52, an air inlet 51, and a drying chamber 40 connected to the above-mentioned air outlet 52 and air inlet 51. The present application sets the heating component 20 at a position close to the air outlet 52, and the blast component 30 is set to blow the gas in the drying chamber 40 out from the air outlet 52. The consumables are dried by the heating component 20, the blast component 30 and the drying material filled in the drying chamber 40.

[0038] In the embodiment of the present application, the heating component 20 is arranged at a position close to the air outlet 52, and the dry gas in the drying chamber 40 is blown out through the air outlet 52 by the blower component 30. At this time, the heating component 20 will heat the blown gas, and the gas will begin to rise after being heated and heated. After absorbing water molecules in the air, it becomes humid gas. Due to factors such as temperature drop or weight increase, it enters the drying chamber 40, and the humid gas is then dried by the drying material filled in the drying chamber 40. The dried gas is then blown out from the air outlet 52 by the blower component 30, thereby forming a self-circulating gas drying channel.

[0039] It should be noted that the heating component 20 provided in the present application can be set not only on the side of the frame close to the air outlet 52, but also on the side outside the frame close to the air outlet 52. Since the consumable material tray 14 is usually large in size, the consumable material tray 14 needs to be set outside the frame; and in order to achieve a better drying effect on the consumables, the present application preferably sets the heating component 20 on the side outside the frame close to the air outlet 52, and sets the consumable material tray 14 above the heating component 20. At this time, the heating component 20 can not only appropriately heat the gas around the consumable material tray 14, but 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.

[0040] Of course, it is also feasible to arrange the heating component 20 on the side of the frame close to the air outlet 52. This arrangement can also achieve the effect of drying the consumables. In this embodiment, the blowing component 30 blows the dry gas in the drying chamber 40 directly to the heating component 20 for heating, and the air outlet 52 blows out the gas that has been heated and heated. At this time, the gas that begins to rise after heating and heating can also achieve the effect of drying the consumables.

[0041] Obviously, whether the heating component 20 is set on the side of the frame close to the air outlet 52 or on the side of the frame close to the air outlet 52, the consumables can be dried. The present application does not impose further restrictions on the specific setting position of the heating component 20, as long as its setting position is capable of heating the gas blown out by the blowing component 30.

[0042] The present application preferably sets the heating component 20 on the side outside the frame close to the air outlet 52 to achieve heating of the gas while heating the gas around the consumable material disk 14. The following explanation of the present application will also be based on setting the heating component 20 on the side outside the frame close to the air outlet 52, but this does not serve as a limitation on the specific setting position of the heating component 20 of the present application, and those skilled in the art should be aware of this.

[0043] As an optional embodiment, please refer to Figure 5, which is a structural schematic diagram of the air inlet 51 in the drying device provided in an embodiment of the present application. In a specific embodiment provided in the present application, the above-mentioned drying chamber 40 includes an upper chamber 41 and a lower chamber 42 that are interconnected up and down, wherein the upper chamber 41 is provided with a first side wall 411 inclined upward, and a plurality of drying holes 412 are provided on the first side wall 411, so that the rising gas after heating can enter the upper chamber 41 through the drying holes 412 provided on the first side wall 411. Since the upper chamber 41 is configured to be filled with drying material, the gas entering the upper chamber 41 is dried under the action of the drying material. At the same time, the inclined upward structure also facilitates the gas that becomes moist after absorbing water molecules to enter the upper chamber 41.

[0044] Specifically, the drying material filled in the upper chamber 41 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 upper chamber 41, any selected drying material is feasible, and multiple drying materials can also be mixed for use. This application does not further explain the specific setting form of the drying material.

[0045] In order to better utilize the internal space of the drying chamber 40, please refer to Figure 4, which is a structural schematic diagram of the blower assembly 30 in the drying device provided in an embodiment of the present application. The present application arranges the blower assembly 30 in the lower chamber 42. Since the upper chamber 41 and the lower chamber 42 are interconnected, the present application arranges the air inlet 51 at the connecting portion between the blower assembly 30 and the upper chamber 41, and arranges the air outlet 52 on the side of the lower chamber 42 close to the heating assembly 20, so that the gas that has been dried in the upper chamber 41 is drawn into the lower chamber 42 from the air inlet 51 through the blower assembly 30, and then blown out to the heating assembly 20 through the air outlet 52, and the blown gas is heated by the heating assembly 20.

[0046] It should be noted that although the present application sets the blowing assembly 30 in the lower chamber 42, its actual blowing flow direction will not blow to the drying material filled in the upper chamber 41, affecting the drying of the moist gas by the drying material. In a specific embodiment, the drying material can be set in the form of a drying bag.

[0047] Since in actual applications, the number of consumable material trays 14 used inside the shell 10 is more than one, and each consumable material tray 14 needs to be provided with a corresponding heating component 20, blowing component 30 and drying chamber 40, the number of heating components 20, blowing components 30 and drying chamber 40 provided in the embodiment of the present application is at least one, and it is necessary to provide heating components 20, blowing components 30 and drying chambers 40 that are no less than the number of consumable material trays 14, so as to dry several consumable material trays 14 at the same time.

[0048] Since several consumable material trays 14 are arranged adjacent to each other, several drying chambers 40 also need to be arranged adjacent to the positions of the several consumable material trays 14. At the same time, several heating components 20 and blowing components 30 also need to be arranged one-to-one with the drying chambers 40 at the corresponding positions. Therefore, this application does not impose specific restrictions on the number of heating components 20, blowing components 30 and drying chambers 40.

[0049] In a specific embodiment provided in the present application, the above-mentioned blowing component 30 can be set as a fan or as other exhaust equipment, such as an exhaust pump; the above-mentioned heating component 20 can be set as an electric heating wire or as other heating components, such as a heating film. As long as it can achieve heating of the gas, any selected heating component 20 is feasible, and the present application does not impose further restrictions on this.

[0050] Based on the above-mentioned drying device, the present application also provides a consumable box, which includes a shell 10 and the above-mentioned drying device. The present application uses the shell 10 to form a closed space to prevent external humid air from entering the consumable box and affecting the consumable material tray 14 placed inside.

[0051] Specifically, the shell 10 includes a shell base 11 and an arc-shaped cover body 12 arranged above the shell base 11. Please refer to Figure 7, which is a structural schematic diagram of the arc-shaped cover body 12 in the drying device provided in an embodiment of the present application. It can be observed that the bottom of the arc-shaped cover body 12 is hinged to the shell base 11 through a hinge 15 and a hinge shaft 16. Of course, in actual applications, the arc-shaped cover body 12 and the shell base 11 can also be hinged through other structures, and this application does not impose further restrictions on this.

[0052] A magnetic part 17 is provided at the position where the top of the arc-shaped cover body 12 is connected to the shell base 11. Specifically, the magnetic part 17 can be set in the form of a magnetic sheet, so that the magnetic part 17 can be used to quickly fix and adsorb the shell base 11. The outer wall of the arc-shaped cover body 12 is provided with an inwardly recessed handle 18. The arc-shaped cover body 12 can be quickly opened and closed by pulling the handle 18 upward and cooperating with the magnetic attraction of the magnetic part 17, so that the working status of each component inside the shell 10 can be checked conveniently.

[0053] As an optional embodiment, the present application sets the frame on one side of the shell 10, forming a cavity with one side wall of the shell 10 for accommodating the blowing assembly 30 and the drying chamber 40, and sets the heating assembly 20 outside the frame but inside the shell 10 and close to the air outlet 52, and sets the consumable material tray 14 above the heating assembly 20. Since the blowing assembly 30 blows air from the air outlet 52 to the position above the heating assembly 20, dry hot air will be generated above the heating assembly 20. After the dry hot air rises, it absorbs water molecules in the air and becomes humid gas, and then enters the drying chamber 40 to complete drying.

[0054] Furthermore, the present application sets the side surface of the arc-shaped cover 12 away from the blowing assembly 30 as an arc-shaped protrusion, so that the gas heated by the heating assembly 20 rises along the arc-shaped guide of the arc-shaped protrusion, and thus a self-circulating gas drying channel is formed inside the shell 10. The gas drying channel includes at least a first drying channel extending from the air outlet 52 toward the heating assembly 20, a second drying channel extending upward from the heating assembly 20 along the arc-shaped guide of the arc-shaped cover 12, and a third drying channel extending from the top of the arc-shaped cover 12 toward the drying chamber 40.

[0055] It should be noted that the gas drying channel provided in the present application includes at least any one of the above-mentioned first drying channel, second drying channel and third drying channel. In principle, gas drying needs to pass through the first drying channel, the second drying channel and the third drying channel, but it does not rule out the possibility that the gas directly enters the third drying channel through the first drying channel, or directly enters the third drying channel through the second drying channel, or directly enters the drying chamber 40 from the third drying channel to achieve drying.

[0056] In an embodiment of the present application, 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 at least two consumable holders 13 are rotatably installed on the inner side wall of the shell 10, and the two consumable holders 13 are arranged in parallel so that the consumable disk 14 wrapped with consumables is placed above the heating component 20, so that the consumables wrapped on the consumable disk 14 are dried through the cooperation of the blowing component 30, the heating component 20 and the drying chamber 40. At the same time, the consumable disk 14 can rotate on the two consumable holders 13 to meet the needs of feeding and returning consumables; at the same time, the inclination degree of the first side wall 411 set in the drying chamber 40 should be adapted to the self-rotation direction of the consumable disk 14, but the distance cannot be too close to affect the normal rotation of the consumable disk 14.

[0057] When several consumable material trays 14 are arranged inside the shell 10, two consumable material brackets 13 need to be correspondingly provided at the bottom of each consumable material tray 14. Therefore, the present application provides a consumable support plate 19 for supporting the consumable bracket 13 at the bottom of two adjacent consumable material trays 14; taking two consumable material trays 14 as an example, at this time, one end of the consumable bracket 13 provided at the bottom is rotatably installed on the inner wall of the shell 10, and the other end of the consumable bracket 13 is rotatably installed on the consumable support plate 19; taking three consumable material trays 14 as an example, at this time, one end of the consumable bracket 13 provided at the bottom of the consumable material trays 14 on the left and right sides is rotatably installed on the inner wall of the shell 10, and the other end of the consumable bracket 13 is rotatably installed on the consumable support plate 19, and both ends of the consumable bracket 13 provided at the bottom of the middle consumable material tray 14 are rotatably installed on the consumable support plate 19, and so on.

[0058] Further, please continue to refer to Figures 2 and 7, which also include a display panel 54 and an inspection window 57 arranged on the outer wall of the shell 10. The present application also provides a control mainboard 53 inside the shell 10. The control mainboard 53 is arranged corresponding to the inspection window 57. The control mainboard 53 can be repaired or adjusted by opening the inspection window 57. At the same time, the control mainboard 53 is connected to the above-mentioned heating component 20, the blower component 30 and the display panel 54 by wired or wireless means. The control mainboard 53 is used to control the working status of the heating component 20 and the blower component 30. The display panel 54 displays the working status of each electrical component in the shell 10 in real time. Of course, the control mainboard 53 can also be connected to other electrical components in the shell 10 that need power supply or control. This application will not go into details here.

[0059] Furthermore, a power interface 58 connected to the above-mentioned control motherboard 53 is also provided at the bottom of the shell 10. The power interface 58 is used to access an external power supply. At the same time, a power switch 59 is also provided on the power interface 58 to control the power usage status inside the shell 10.

[0060] As an optional embodiment, in order to realize the free combination application of multiple drying devices, if it is necessary to realize the simultaneous printing of several consumable material trays 14, please refer to Figure 6, which is a structural schematic diagram of the docking female head 56 in the drying device provided in an embodiment of the present application. The present application is provided with a docking male head 55 and a docking female head 56 on the outer wall of the shell 10. By plugging the docking male head 55 of the current shell 10 with the docking female head 56 of another shell 10, and / or plugging the docking female head 56 of the current shell 10 with the docking male head 55 of another shell 10, the arrangement and plugging requirements of multiple shells 10 are realized.

[0061] Based on the above-mentioned drying device, the present application also provides a 3D printer, including the consumable box provided in the above-mentioned embodiment. Since the consumables wrapped on the consumable disk 14 need to be applied during the 3D printing process, and the dryness of the consumables needs to be ensured during the printing process, 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, thereby improving the quality of the 3D printed product.

[0062] 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 setting a self-circulating gas drying channel in the shell, and cooperating with the heating component, the blowing component and the drying chamber. Since the gas inside the shell is continuously blown to the top of the heating component by the blowing component, the dried hot air rises along the arc of the arc-shaped cover, and the humid gas after absorbing water molecules in the air descends into the drying chamber due to factors such as temperature drop or mass increase, and the humid gas is dried by the desiccant filled in the drying chamber; the blowing component continuously blows air to the top of the heating component through the air outlet, thereby accelerating the circulation and drying of the gas inside the shell and greatly shortening the drying time; at the same time, the consumable material tray wrapped with consumables is mounted above the heating component, so the heating component 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 printing consumables, ensuring the final 3D printing effect.

[0063] It can be understood that the various technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments are merely exemplary embodiments for illustrating the principles of the present application, but the present application is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present application, and such modifications and improvements are also considered to be within the scope of protection of the present application.
