DETAILED DESCRIPTION

[0087] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be described in more detail below in conjunction with the drawings in the preferred embodiments of the utility model.

[0088] like Figure 1 As shown, an embodiment of the utility model provides a material trough of a 3D printer, which is used to store materials to be cured. The material trough includes a material trough body 1; a first electrical component 2 is arranged on the material trough body 1. When the material trough body 1 is installed on the 3D printer, the first electrical component 2 is electrically connected to the main board of the 3D printer.

[0089] The material trough of the 3D printer provided by the embodiment of the utility model is provided with a first electrical component 2 on the material trough body 1, and when the material trough body 1 is installed on the 3D printer, the first electrical component 2 can be electrically connected to the main board of the 3D printer, so that the material trough can communicate with the main board of the 3D printer through the first electrical component 2 or the material trough can realize power supply of electronic devices or circuits set on the material trough through the first electrical component 2, so that it is convenient to connect peripherals to the material trough to enrich the function of the material trough, and the communication between the material trough and the main board is also conducive to realizing the intelligence and multi-function of the material trough, thereby making the material trough more conducive to meeting the development needs of the printer.

[0090] In some embodiments, see Figure 1 and Figure 3 The first electrical component 2 may include a control board 21 and a conductive connector 22 electrically connected to the control board 21, the control board 21 is disposed on the trough body 1, and the conductive connector 22 is disposed on the trough body 1; the conductive connector 22 is used to be electrically connected to the main board of the 3D printer.

[0091] When the trough body 1 is installed on a 3D printer, the conductive connector 22 can be electrically connected to the mainboard of the 3D printer, so that the control board 21 of the trough is electrically connected to the mainboard of the 3D printer, thereby realizing power supply of the trough and communication with the mainboard.

[0092] The conductive connector 22 may have a variety of structural forms, as long as it can achieve electrical connection with the mainboard of the 3D printer. For example, the conductive connector 22 may be an electrical plug, and accordingly, the mainboard of the 3D printer may be electrically connected to an electrical socket. When the trough body 1 is installed on the 3D printer, the electrical plug may be inserted into the electrical socket to achieve electrical connection between the control board and the mainboard; or, the conductive connector 22 may be a first wiring terminal, and accordingly, the mainboard of the 3D printer may be electrically connected to a second wiring terminal. When the trough body 1 is installed on the 3D printer, the first wiring terminal and the second wiring terminal are electrically connected to achieve electrical connection between the control board and the mainboard.

[0093] In some embodiments, see Figure 2 and Figure 7 , and combined with Fig. 9 and Fig.10 , the conductive connector 22 can be a first contact; a second contact 101 electrically connected to the mainboard can be provided on the base 3 of the 3D printer; when the trough body 1 is installed on the base 3, the first contact contacts the second contact 101 to enable the control board 21 to communicate with the mainboard.

[0094] After the 3D printer is finished printing, the material tank usually needs to be removed and cleaned. Moreover, after a period of use, the material tank also usually needs to be removed to maintain or replace the release film assembly, that is, the material tank needs to be frequently removed or installed on the base 3.

[0095] In the above embodiment, the conductive connector 22 is set as the first contact, and correspondingly, the second contact 101 electrically connected to the mainboard is set on the base 3. Since the electrical connection can be achieved when the first contact and the second contact 101 are in contact, and the electrical connection can be disconnected when they are separated, therefore, when the trough body 1 is installed on the base 3 and the first contact is in contact with the second contact 101, the control board 21 can communicate with the mainboard; when the trough needs to be removed, the trough can be directly removed, and the first contact and the second contact 101 can be disconnected, thereby disconnecting the electrical connection between the control board 21 and the mainboard. In this process, there is no need to perform operations such as plugging and unplugging, wiring, etc. to achieve electrical connection, and disassembly and assembly of the trough is convenient and quick.

[0096] The first contact point may have various structural forms, as long as it can achieve electrical connection with the second contact point when in contact.

[0097] In some embodiments, the first contact may include at least one metal pad, at least one conductive sheet, or at least one metal spring sheet. Correspondingly, the second contact may also include at least one metal pad, at least one conductive sheet, or at least one metal spring sheet, and the two may be combined in any way as long as electrical connection is achieved when in contact.

[0098] In some embodiments, the first contact includes one or more of the following contacts: a first power supply contact, a first detection contact, and a first communication contact; the second contact 101 includes one or more of the following contacts: a second power supply contact, a second detection contact, and a second communication contact.

[0099] Among them, if the first contact includes a first power supply contact, and the second contact 101 includes a second power supply contact, then when the trough body 1 is installed on the base 3, the first power supply contact is in contact with the second power supply contact, so that the mainboard supplies power to the control board 21; if the first contact includes a first detection contact, and the second contact 101 includes a second detection contact, then when the trough body 1 is installed on the base 3, the first detection contact is in contact with the second detection contact, so that the control board 21 transmits an electrical signal to the mainboard, and the electrical signal is used to indicate whether the trough body 1 is installed in place on the base 3; if the first contact includes a first communication contact, and the second contact 101 includes a second communication contact, then when the trough body 1 is installed on the base 3, the first communication contact is in contact with the second communication contact, so that the control board 21 communicates with the mainboard.

[0100] When the trough body 1 is installed on the base 3: the first power supply contact can contact the second power supply contact so that the main board supplies power to the control board; the first detection contact can contact the second detection contact so that the control board transmits an electrical signal to the main board, and the electrical signal is used to indicate whether the trough body 1 is installed in place on the base 3, which can avoid the second electrical component on the base 3 from being powered when the trough is not installed in place, and thus helps to avoid the safety problems that may be caused by the contacts being mistakenly contacted by the human body or other objects in the above situation; the first communication contact contacts the second communication contact so that the control board communicates with the main board, which is convenient for transmitting the operating data of each component on the transmission trough to the main board, thereby realizing intelligent monitoring.

[0101] In some specific embodiments, the first contact may further include at least one first reserved contact, and, see Figure 4 At least one reserved interface 15 electrically connected to the first reserved contact can be provided on the trough body 1 for connecting other peripherals. The second contact 101 can also include at least one second reserved contact, so that when the trough is connected to other peripherals, data can be transmitted with the mainboard of the 3D printer through the reserved contact.

[0102] In some embodiments, see Figure 2 and Figure 7The first electrical component 2 may also include a first connecting portion 27, which is arranged on the trough body 1, and a first limiting portion is arranged on the first connecting portion 27; the first contact is arranged on the first connecting portion 27; a second connecting portion 31 may be arranged on the base 3, a second limiting portion is arranged on the second connecting portion 31, and a second contact is arranged on the second connecting portion 31; when the trough body 1 is installed on the base 3, the first limiting portion and the second limiting portion are connected.

[0103] In the above embodiment, by providing the first limiting portion and the second limiting portion, and when the trough body 1 is installed on the base 3, the first limiting portion and the second limiting portion are connected, thereby realizing the limited installation of the trough body 1 on the base 3. In this way, it can be ensured that each functional contact in the first contact point is in corresponding contact with each functional contact in the second contact point 101, thereby avoiding the functional contacts from being wrongly connected or poorly connected, causing circuit failure or short circuit, etc.

[0104] In some embodiments, see Figure 2 and Figure 7 One of the first limiting portion and the second limiting portion may include at least two limiting holes 3111, and the other of the first limiting portion and the second limiting portion may include at least two limiting columns 2711; when the trough body 1 is installed on the base 3, the limiting columns 2711 are inserted into the corresponding limiting holes 3111.

[0105] In the process of installing the trough body 1 on the base 3, the limiting column 2711 can be gradually inserted into the corresponding limiting hole 3111 until the limiting column 2711 is plugged into the limiting hole 3111, and the trough body 1 is installed in place on the base 3, and each functional contact of the first contact is in corresponding contact with each functional contact of the second contact. In this process, the limiting column 2711 and the limiting hole 3111 play a limiting role on the trough body 1, avoiding the first contact and the second contact from being misconnected or virtual connected. Accordingly, when removing the trough, the trough body 1 can be lifted up so that the limiting column 2711 is separated from the corresponding limiting hole 3111, and the trough can be separated from the base 3. In other words, the limiting structure of the limiting hole 3111 and the limiting column 2711 are used to limit the installation of the trough on the base 3, which can facilitate the disassembly and assembly of the trough, and the limiting structure is simple and reliable to use.

[0106] To further facilitate operation, in some embodiments, the first limiting portion may include at least two limiting holes 3111 , and the second limiting portion may include at least two limiting columns 2711 .

[0107] In some embodiments, see Figure 4 , Figure 7 and Figure 8The first connection part 27 may include a first shell 271 and a first adapter plate 272 disposed in the first shell 271. The first shell 271 is disposed on the trough body. Specifically, the first shell 271 is disposed on the side of the trough body. The first contact is disposed on the first adapter plate 272. The first adapter plate 272 is electrically connected to the control board. The first shell 271 may be provided with a first opening. The first contact is exposed outside the first shell 271 through the first opening.

[0108] The second connecting portion 31 may include a second shell 311 and a second adapter plate 102. The second shell 311 is arranged on the base 3. Specifically, the second shell 311 can be arranged on the upper bottom plate of the base 3, and the second contact is arranged on the second adapter plate 102. A second opening can be opened on the second shell 311, and the second contact 101 is exposed outside the second shell 311 through the second opening, so that when the trough body 1 is installed on the base 3, the first contact and the second contact 101 are in contact.

[0109] Specifically, the limiting hole 3111 can be opened on the first shell 271, and the number of the limiting holes 3111 can be four, and the four limiting holes 3111 can be arranged at the four corners of the first shell 271. The limiting column 2711 can be set on the second shell 311, and the number of the limiting columns 2711 can be four, and the four limiting columns can be arranged at the four corners of the second shell 311. Specifically, the second shell 311 can be connected with the upper bottom plate of the base by screws, and the number of screws can be four, and the screw heads of the four screws can be protruded from the surface of the second shell 311. Therefore, the screw heads of the four screws can be used as four limiting columns 2711, so there is no need to set additional limiting columns 2711, and the structure is simple and reliable.

[0110] If the material tank causes the to-be-cured material to leak out due to an unexpected situation, the leaked to-be-cured material may invade the conductive structure of the second connecting portion 31. In order to avoid this problem, in some embodiments, see Figure 7 At least the setting surface of the second contact on the second connecting part 31 protrudes from the surface of the base 3, which can prevent the outflow of the to-be-cured material from flowing into the second connecting part 31, thereby avoiding the to-be-cured material from damaging the conductive structure, thereby ensuring the electrical connection stability between the material tank and the mainboard of the 3D printer, and extending the service life of the material tank.

[0111] It should be noted that the main body of the second connection part 31 can be a plastic part, that is, the second shell 311 can be made of plastic material, so that the second connection part 31 has insulation and corrosion resistance, thereby preventing the second connection part 31 from being corroded by the infiltrated material to be cured.

[0112] In some embodiments, the area on the base 3 corresponding to the trough body 1 is provided with a corrosion-resistant layer, which mainly plays the role of insulation and corrosion resistance. The corrosion-resistant layer can prevent the infiltrated material to be solidified from corroding the upper bottom plate of the base. Specifically, the corrosion-resistant layer can be a plastic layer, and can be attached to the upper bottom plate of the base 3.

[0113] In some embodiments, see Figure 2 The trough body 1 may include a release film assembly and multiple side walls, which define a storage cavity 11 for storing the material to be cured; a flow channel 12 is opened on the side wall, and the inlet and outlet of the flow channel 12 are respectively connected to the storage cavity 11; the first electrical component 2 may also include a driving member 23, which is arranged on the trough body 1 and electrically connected to the control board 21, and the driving member 23 is used to drive the material to be cured to circulate between the storage cavity 11 and the flow channel 12.

[0114] When the trough body 1 is installed on the base 3, the main board of the 3D printer can issue instructions to start the driving member 23 to drive the material to be cured to circulate between the storage chamber 11 and the flow channel 12, thereby realizing functions such as cyclic heating or cyclic heat dissipation of the material to be cured.

[0115] In some embodiments, the aforementioned flow channel 12 can be arranged along the circumference of the trough body 1, and the inlet of the flow channel 12 can be located at the first end of the trough body 1, and the outlet of the flow channel 12 can be located at the second end of the trough body 1, and the first end and the second end are opposite.

[0116] The inlet and outlet of the flow channel 12 are respectively located at the first end and the second end of the trough body 1, which can extend the flow path of the material to be solidified, thereby improving the circulation efficiency of the material to be solidified. Moreover, the number of the inlet and / or outlet of the flow channel 12 can be multiple, and the multiple inlets can be arranged at intervals along the length direction of the first end, and / or the multiple outlets can be arranged at intervals along the length direction of the second end.

[0117] Moreover, the flow channel 12 may be a flow channel formed by a groove provided on the bottom surface of the side wall and a release film assembly, and the flow channel 12 may be extended along half of the trough body 1, so that the material to be cured circulates along half of the trough body 1; or the flow channel 12 may be arranged along the entire circumference of the trough body 1, so that the material to be cured circulates along the entire circumference of the trough body 1 in two ways. It can be understood that compared with the case where the flow channel 12 is extended along half of the trough body 1, the flow channel 12 is arranged along the entire circumference of the trough body 1, and the driving ability of the driving member 23 and the sealing performance of the flow channel 12 are required to be higher. Therefore, in specific implementation, the setting of the flow channel 12 can be determined according to the driving ability of the driving member 23 and the sealing performance of the flow channel 12.

[0118] In some embodiments, see Figure 1and Figure 2 The material tank of the 3D printer may further include a filter assembly 4, which is disposed in the material storage chamber 11; and / or, the filter assembly 4 is disposed in the flow channel 12, for filtering the material to be cured. During the process of the material to be cured circulating between the material storage chamber 11 and the flow channel 12, the filter assembly 4 may filter out impurities such as residues in the material to be cured, thereby preventing the impurities from damaging the exposure screen and printing platform of the 3D printer.

[0119] In some embodiments, see Figure 6 The filter assembly 4 may include a filter element 41 and a connector 42 connected to the filter element 41 . The connector 42 is detachably connected to the trough body 1 . The filter element 41 is used to filter the material to be cured.

[0120] The filter assembly 4 is detachably connected to the trough body 1 via a connector 42 . After the filter assembly 4 has been used for a period of time, it can be removed from the trough body 1 for cleaning or replacement to ensure the filtering effect of the filter assembly 4 .

[0121] In some embodiments, see Figure 6 The connecting member 42 may include a hook 421, and the hook 421 is hung on the top edge of the trough body 1; moreover, the filter 41 may be located in the storage cavity 11, and the filter 41 corresponds to the inlet of the flow channel 12.

[0122] Since the filter assembly 4 is hung on the trough body 1 by the hook 421, the user can directly remove the filter assembly 4 from the trough body 1 after using the filter assembly 4 for a period of time, and then hang the filter assembly 4 on the trough body 1 again after cleaning or replacing the filter assembly 4. The filter assembly 4 is hung on the trough body 1 by the hook 421, which is a detachable connection method, so that the filter assembly 4 can be more conveniently and quickly disassembled from the trough body 1.

[0123] Among them, the filter element 41 is located in the material storage chamber 11 and corresponds to the entrance of the flow channel 12, so that the circulating material to be solidified can enter the flow channel 12 through the filter element 41. On the one hand, the filtering effect of the material to be solidified by the filter component 4 is ensured, and on the other hand, the filter component 4 is hung on the material trough body 1.

[0124] In some embodiments, see Figure 1 and Figure 2 The storage chamber 11 may include a first side and a second side opposite to each other; the filter element 41 extends from the first side to the second side, and a plurality of filter holes 411 are provided on the filter element 41, and the storage chamber 11 and the flow channel 12 are connected through the filter holes 411.

[0125] Among them, the filter element 41 extends from the first side of the storage chamber 11 to the second side, that is, the filter element 41 can span the entire storage chamber 11, so that the circulating material to be cured can all be filtered through the filter element 41, so that more impurities can be deposited on the filter element 41, thereby further improving the filtering effect of the filter component 4 on the material to be cured.

[0126] Moreover, the filter element 41 may be in a groove shape to facilitate installation of the filter element 41 in the material storage cavity 11 .

[0127] In some embodiments, see Figure 1 The aforementioned driving member 23 may be a peristaltic pump, which may include a peristaltic pump body 231 and a peristaltic tube body 232 arranged on the peristaltic pump body 231; the inlet of the peristaltic tube body 232 is connected to the material storage chamber 11, and the outlet of the peristaltic tube body 232 is connected to the flow channel 12, and the peristaltic tube body 232 is used to transport the material to be solidified; the peristaltic pump body 231 is used to roll and press the peristaltic tube body 232 to drive the material to be solidified to circulate between the material storage chamber 11 and the flow channel 12.

[0128] Among them, the peristaltic pump body 323 continuously rolls and presses the peristaltic tube body 232, so that the material to be solidified in the storage chamber 11 is continuously sucked into the peristaltic tube body 232, and then discharged to the flow channel 12 through the peristaltic tube body 232, finally realizing the circulation flow of the material to be solidified between the storage chamber 11 and the flow channel 12.

[0129] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The first electrical component 2 may further include a heating element 24 , which is connected to the trough body 1 and is used to heat the trough body 1 . The heating element 24 is also electrically connected to the control board 21 .

[0130] Among them, the heating element 24 can heat the trough body 1, and the trough body 1 can transfer heat to the material to be cured in the storage chamber 11, so as to achieve heating of the material to be cured. In a working environment with a lower temperature such as winter, heating the material to be cured can increase the activity of the material to be cured, thereby improving the success rate of printing the model by the 3D printer; moreover, it can cooperate with the circulation flow of the material to be cured to achieve cyclic heating of the material to be cured, which can better improve the activity of the material to be cured, thereby further improving the success rate of printing the model by the 3D printer. Specifically, the heating element 24 can be a heating rod. The outer sleeve of the heating rod is provided with an anti-corrosion cylindrical tube, which can prevent the heating element 24 from being corroded by the material to be cured.

[0131] In some embodiments, see Figure 3 , Figure 4 and Figure 5The first electrical component 2 may further include a first detection member 25 , which is electrically connected to the control board 21 and is used to detect the temperature of the trough body 1 .

[0132] The first detection member 25 is electrically connected to the control board 21, and the control board 21 can receive the temperature information fed back by the first detection member 25, and upload the temperature information to the main board of the 3D printer to achieve temperature control of the material to be cured. Specifically, the first detection member 25 can be a temperature sensor, such as a cylindrical metal thermistor, and the outer sleeve of the cylindrical metal thermistor is provided with an anti-corrosion cylindrical tube to prevent the first detection member 25 from being corroded by the material to be cured.

[0133] In some embodiments, see Figure 3 The first electrical component 2 may further include a second detection member 26 , which is electrically connected to the control board 21 and is used to detect the liquid level and temperature of the material to be cured in the trough body 1 .

[0134] The second detection member 26 is electrically connected to the control board 21, and the control board 21 can receive the liquid level information and temperature information fed back by the second detection member 25, and upload the liquid level information and temperature information to the main board of the 3D printer to achieve liquid level and temperature control of the material to be cured. The second detection member 26 can have various structural forms, for example, it can include a liquid level sensor and a temperature sensor, the liquid level sensor is used to detect the liquid level of the material to be cured, and the temperature sensor is used to detect the temperature of the material to be cured.

[0135] In some embodiments, see Figure 1 The second detection member 26 may include a circuit board 261 and a metal member 262. The circuit board 261 is disposed on the inner side of the trough body 1 and is electrically connected to the control board 21. The metal member 262 is disposed on the circuit board 261 and extends along the liquid level height of the material to be cured. The metal member 262 is used to contact the material to be cured so that the circuit board 261 generates a first electrical signal corresponding to the liquid level of the material to be cured.

[0136] Among them, since the material to be cured has a certain internal resistance, when the material to be cured contacts the metal part 262 on the circuit board 261, the metal part 262 can send a corresponding electrical signal to the control board 21 through the circuit board 261, so that the control board 21 obtains the liquid level information of the material to be cured. Compared with the use of detection parts such as liquid level sensors, the second detection part 26 has a simple structure and low cost.

[0137] See also Figure 1The second detection member 26 may further include a temperature sensor 263, which is disposed on the circuit board 261 and is used to detect the temperature of the material to be cured and send the temperature information to the control board 21 through the circuit board. Specifically, the temperature sensor 263 may be a thermistor.

[0138] In some embodiments, see Figure 1 and Figure 4 A plurality of heat dissipation fins 13 may be provided on the trough body 1, and the plurality of heat dissipation fins 13 are arranged at intervals from each other.

[0139] During the printing process of the 3D printer, when the energy temperature of the material to be cured is too high due to the curing light, the heating element 24 can be turned off and the driving element 23 can be turned on to achieve cyclic heat dissipation of the material to be cured, so that the material to be cured is kept in a reasonable temperature range. In the above embodiment, by providing a plurality of heat dissipation fins 13, the heat dissipation area of ​​the trough body 1 is increased, which is more conducive to the transfer of heat from the trough body 1 to the air, thereby further improving the cyclic heat dissipation effect of the material to be cured.

[0140] In some embodiments, the plurality of heat dissipation fins 13 may extend from the outer side of the tank body 1 to a direction away from the outer side of the tank body 1; or, see Figure 1 The top surface of the trough body 1 is provided with a plurality of grooves 14 penetrating the outer side of the trough body 1, and a heat dissipation fin 13 is formed between two adjacent grooves 14. In the embodiment where a heat dissipation fin 13 is formed between two adjacent grooves 14, the overall volume of the trough body 1 may not be changed, which is conducive to the installation of the trough body 1 on the base 3. In the specific implementation, it can be selected according to the actual situation such as the installation space of the trough.

[0141] An embodiment of the utility model further provides a three-dimensional printer, comprising the material trough of the aforementioned three-dimensional printer.

[0142] The 3D printer provided by the embodiment of the utility model includes the material trough of the 3D printer mentioned above, and therefore, the 3D printer has all the beneficial effects of the material trough of the 3D printer, which will not be described in detail here.

[0143] like Fig. 9 and Fig.10 As shown, an embodiment of the utility model further provides a three-dimensional printer, comprising a base 3, a main board arranged in the base 3, and the aforementioned material trough of the three-dimensional printer; a second electrical component electrically connected to the main board is arranged on the base 3, and the second electrical component includes the aforementioned second connecting portion 31. When the material trough is installed on the base 3, the first electrical component 2 is electrically connected to the main board through the second electrical component.

[0144] The three-dimensional printer provided by the embodiment of the utility model is provided with a first electrical component 2 on the trough body 1 of the trough, and a second electrical component electrically connected to the main board is provided on the base. When the trough is installed on the base 3, the first electrical component 2 is electrically connected to the second electrical component, that is, the first electrical component 2 is electrically connected to the main board of the three-dimensional printer through the second electrical component, so that the trough can communicate with the main board of the three-dimensional printer, which can facilitate the realization of intelligence and multi-function of the trough, thereby making the trough more conducive to meeting the development needs of the printer.

[0145] In some embodiments, see Fig. 9 and Fig.10 The first electrical component 2 may include a control board 21 and a first contact electrically connected to the control board 21; the second electrical component may include a second adapter board 102 and a second contact 101 electrically connected to the second adapter board 102, and the second adapter board 102 is electrically connected to the main board; when the material trough is installed on the base 3, the first contact contacts the second contact 101 to enable the control board 21 to communicate with the main board; when the material trough is detached from the base 3, the first contact is separated from the second contact 101.

[0146] That is to say, when the material trough is installed on the base 3, electrical connection can be achieved when the first contact and the second contact 101 are in contact, thereby realizing the electrical connection between the control board 21 and the main board. When the material trough is removed, the first contact and the second contact 101 are separated to disconnect the electrical connection, thereby disconnecting the electrical connection between the control board 21 and the main board. In this process, there is no need to perform operations such as plugging and unplugging, wiring, etc. to achieve electrical connection, and disassembly and assembly of the material trough is convenient and quick.

[0147] In some embodiments, one of the first contact and the second contact 101 includes at least one metal pad, and the other of the first contact and the second contact 101 includes at least one metal spring; or, both the first contact and the second contact 101 include at least one metal pad; or, both the first contact and the second contact 101 include at least one metal spring. Regardless of the structural form of the first contact and the second contact 101, as long as the two can achieve contact, that is, conduction, and separation, that is, disconnection, the present application does not limit this.

[0148] In some embodiments, the second adapter board 102 can be electrically connected to the main board through a switching circuit; the 3D printer can also include a third detection component, which is electrically connected to the main board, and the third detection component is used to be triggered when a material trough is installed on the base 3 to generate a corresponding second electrical signal; the main board controls the switching circuit to be turned on at least when receiving the second electrical signal to power the second contact 101.

[0149] When the trough is installed on the base 3, the third detection member can detect whether the trough is installed, that is, detect whether the first contact and the second contact 101 are in good contact, and after the trough is installed, send a second electrical signal to the main board, and the main board determines that the trough has been installed according to the second electrical signal, thereby controlling the switch circuit to be turned on, so as to supply power to the second contact 101 through the second adapter board 102, otherwise, the main board controls the switch circuit to be turned off, and the second contact 101 is not charged. In other words, the second contact 101 will be charged only when the trough and the base 3 are installed and in good contact, so as to realize the communication between the control board 21 of the trough and the main board; if the trough leaves the base 3, the second contact 101 is not charged, which can prevent other conductive objects from contacting the charged second contact 101 when the trough is removed, resulting in a short circuit and burning the main board, and can also prevent the second contact 101 from being charged and contacting the first contact of the trough when the trough is to be installed on the base 3, so that both the main board and the control board 21 of the trough are protected and foolproof.

[0150] It can be understood that, in specific implementation, the conditions for the mainboard to control the switch circuit to be turned on include not only that the material trough has been installed on the base 3, but also that the mainboard has obtained a print instruction. That is to say, when the mainboard determines that the material trough has been installed on the base 3, at the same time, the mainboard has also obtained a print instruction, such as the user pressing the print button on the control screen of the printer. In this case, the mainboard controls the switch circuit to be turned on to supply power to the second contact 101 through the second adapter board 102. Otherwise, the mainboard controls the switch circuit to be disconnected, and the second contact 101 is not powered to avoid energy waste and to make it more convenient to use.

[0151] The third detection component may include a photoelectric sensor, a proximity switch or other sensor that can be used to detect whether the material trough is installed in place.

[0152] In some embodiments, the third detection member may be a detection pin, which is used to generate a level flip signal when a material trough is installed on the base 3, and the level flip signal is a second electrical signal.

[0153] An embodiment of the utility model also provides a base of a 3D printer, which is applied to the 3D printer. The base may include a base body, in which a main board is arranged; a second electrical component is arranged on the base body and electrically connected to the main board. When the material trough of the 3D printer is installed on the 3D printer, the second electrical component is electrically connected to the material trough.

[0154] The base of the 3D printer provided by the embodiment of the utility model realizes that when the material trough of the 3D printer is installed on the 3D printer, the second electrical component electrically connected to the main board is arranged on the base body, so that the second electrical component can be electrically connected to the material trough. Specifically, the second electrical component can be electrically connected to the first electrical component 2 of the material trough, so that the material trough can communicate with the main board of the 3D printer, which can facilitate the material trough to realize intelligence and multi-function, thereby making the material trough more conducive to meeting the development needs of the printer.
