Description

Technical Field

[0002] Fused Deposition Modeling (FDM) is a method that uses heated and melted filaments to print and deposit them layer by layer to form a three-dimensional object.

[0003] When the nozzles of a 3D printer become clogged, the nozzles need to be removed from the printer, cleaned, and reinstalled. If the nozzles are severely clogged, they may even need to be replaced. Therefore, the ease of nozzle removal and installation is very important.

[0004] In related technologies, nozzles often do not have a quick-release function. Even if some nozzles can be quick-released, the disassembly process is cumbersome and requires the use of other tools, which seriously affects the loading and unloading efficiency. Summary of the Invention

Detailed Implementation

[0031] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0032] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] Please refer to Figures 1 to 28 The nozzle module in this embodiment includes a heat dissipation assembly 1, a locking assembly 2, and a nozzle assembly 3. The locking assembly 2 includes a clamping ring 201 and a rotating member 202. The clamping ring 201 is fixed to the heat dissipation assembly 1, and the rotating member 202 is rotatably connected to the clamping ring 201. The clamping ring 201 has a clamping hole 2011 and an opening 2012, both of which penetrate the clamping ring 201 in a first direction, and the opening 2012 communicates with the clamping hole 2011. The nozzle assembly 3 is sequentially disposed in the clamping hole 2011 and the heat dissipation assembly 1 along the first direction. The rotating member 202 can rotate relative to the clamping ring 201 in the S-direction, and can also rotate relative to the clamping ring 201 in the N-direction, where the N-direction is the opposite direction of the S-direction. As the toggle member 202 rotates relative to the clamping ring member 201 along the S-direction, the width of the opening 2012 gradually decreases, causing the diameter of the clamping hole 2011 to gradually decrease, thereby allowing the clamping ring member 201 to gradually clamp the nozzle assembly 3. When the toggle member 202 rotates along the S-direction to the up position, the nozzle assembly 3 is clamped by the clamping ring member 201 within the clamping hole 2011, as shown in the up position. Figure 7 and Figure 16 As shown, during the rotation of the torsion member 202 relative to the clamping ring member 201 in the N direction, the width W1 of the opening 2012 gradually increases, and the diameter of the clamping hole 2011 gradually increases, thereby allowing the clamping ring member 201 to gradually release the nozzle assembly 3. Please refer to... Figure 8 As shown, when the knob 202 is rotated in the N direction to the lowered state, the clamping ring 201 can release the nozzle assembly 3, making it easy for the user to remove the nozzle assembly 3 from the nozzle module.

[0035] In this embodiment, the width W1 of the opening 2012 can be changed by rotating the toggle component 202, thereby changing the diameter of the clamping hole 2011. This allows the clamping ring component 201 to clamp or release the nozzle assembly 3 that passes through the clamping hole 2011. This not only enables quick installation and disassembly with a single twist, but also simplifies the installation and disassembly process, eliminating the need for other tools and improving installation and disassembly efficiency. Furthermore, the locking component 2 reliably fixes the nozzle assembly 3 to the heat dissipation component 1, solving the problem of the nozzle assembly 3 rotating and / or moving up and down during movement, thus achieving reliable fixation of the nozzle assembly 3.

[0036] In some embodiments, the clamping ring 201 is elastic. Therefore, when the toggle 202 rotates relative to the clamping ring 201, increasing the width W1 of the opening 2012, the nozzle assembly 3 can disengage from the clamping ring 201 under its own gravity. This effectively prevents the clamping ring 201 from still clamping the nozzle assembly 3 when the toggle 202 is rotated to the lowered state, further ensuring that the nozzle module can be quickly disassembled and improving disassembly efficiency.

[0037] In some embodiments, when the clamping ring 201 clamps the nozzle assembly 3, the opening 2012 still has a certain width. That is, in this embodiment, rotating the toggle 202 along the S direction can change the width W1 of the opening 2012, but will not cause the opening 2012 to close completely, thus reserving a certain deformation. This avoids the opening 2012 closing before the toggle 202 has been rotated to the correct position, which would prevent the nozzle assembly 3 from being unable to be effectively clamped. This improves the reliability of the nozzle module and allows the clamping ring 201 to clamp the nozzle assembly 3 more effectively.

[0038] In some embodiments, the clamping ring 201 has two opposing fixed abutment portions 2013, which are respectively disposed on both sides of the opening 2012 in a second direction, wherein the second direction is perpendicular to the first direction and is the width direction of the opening 2012. The toggle member 202 includes a rotating abutment portion 2021, which is correspondingly disposed with the fixed abutment portion 2013. The rotating abutment portion 2021 has a first mating surface 20211, and the fixed abutment portion 2013 has a second mating surface 20132, which can abut against each other in the second direction. When the rotating abutment portion 2021 rotates relative to the fixed abutment portion 2013 in the S direction, the first mating surface 20211 presses against the second mating surface 20132 in the second direction, thereby reducing the width W1 of the opening 2012 and the diameter of the clamping hole 2011. When the rotating support part 2021 rotates relative to the fixed support part 2013 in the N direction, the first mating surface 20211 releases the second mating surface 20132 in the second direction. Releasing the second mating surface 20132 in the second direction means reducing or releasing the constraint of the first mating surface 20211 on the second mating surface 20132 in the second direction, so that the second mating surface 20132 can gradually return to the position where it was in the lowered state. Therefore, the release of the second mating surface 20132 in the second direction by the first mating surface 20211 increases the width W1 of the opening 2012 and the diameter of the clamping hole 2011, thereby allowing the nozzle assembly 3 to disengage from the clamping ring 201 under its own gravity, making it easier for the user to remove the nozzle assembly 3 from the nozzle module.

[0039] As an example, the first mating surface 20211 can be a cam surface, please refer to... Figure 3 as well as Figures 7 to 9 As shown. Alternatively, the first mating surface 20211 and the second mating surface 20132 can be mutually mating wedge-shaped surfaces, please refer to [reference needed]. Figures 17 to 26 As shown. Alternatively, the first mating surface 20211 and the second mating surface 20132 can also be other shapes, which can be set according to the actual situation.

[0040] In some implementation methods, please refer to Figures 1 to 9 In the illustrated embodiment, the toggle member 202 includes a rotating abutment portion 2021 and two fixed abutment portions 2013, namely a first fixed abutment portion 2013a and a second fixed abutment portion 2013b. The rotating abutment portion 2021 is disposed on the side of the first fixed abutment portion 2013a opposite to the second fixed abutment portion 2013b, and the end face of the side of the first fixed abutment portion 2013a opposite to the second fixed abutment portion 2013b is constructed as a second mating surface 20132.

[0041] In this embodiment, when the torsion member 202 rotates along the S direction to Figure 7 During the process of the clamped state shown, the first mating surface 20211 of the fixed support portion 2013 can press the second mating surface 20132 of the first fixed support portion 2013a along the second direction, so that the first fixed support portion 2013a moves towards the second fixed support portion 2013b along the second direction, thereby reducing the width W1 of the opening 2012 in the second direction, so that the clamping ring 201 can apply pressure to the nozzle assembly 3 to clamp the nozzle assembly 3. When the toggle member 202 rotates along the N direction to Figure 8 During the lowering process shown, the knob 202 can release the first fixed support portion 2013a in the second direction, so that the first fixed support portion 2013a moves away from the second fixed support portion 2013b in the second direction to increase the width W1 of the opening 2012 in the second direction, thereby allowing the clamping ring 201 to release the nozzle assembly 3, making it easier for the user to remove the nozzle assembly 3 from the nozzle module.

[0042] As one implementation method, please refer to Figures 7 to 9 The first mating surface 20211 can be a cam surface, with its central axis eccentrically positioned relative to the first axis 7. The first axis 7 is perpendicular to the second direction, and the relative position of the first axis 7 and the second fixed abutment 2013b is fixed. That is, the second fixed abutment 2013b remains stationary, while the first fixed abutment 2013a can move along the second direction. When the toggle member 202 rotates about the first axis 7 in the S direction, the first mating surface 20211 presses against the second mating surface 20132 in the second direction, thereby allowing the first fixed abutment 2013a to move towards the second fixed abutment 2013b in the second direction. When the toggle member 202 rotates about the first axis 7 in the N direction, the first mating surface 20211 releases the second mating surface 20132 in the second direction, thereby allowing the first fixed abutment 2013a to move away from the second fixed abutment 2013b in the second direction.

[0043] The working principle of this embodiment is as follows: when the torsion member 202 rotates along the S direction to... Figure 7 When the lever is in the extended position, the distance between the first axis 7 and the second fixed abutment 2013b is at or near its maximum value. Since the relative positions of the first axis 7 and the second fixed abutment 2013b are fixed, that is, the distance between the first axis 7 and the first fixed abutment 2013a in the second direction is fixed. Therefore, the distance between the first fixed abutment 2013a and the second fixed abutment 2013b in the second direction is at or near its minimum value, meaning the width W1 of the opening 2012 in the second direction is at or near its minimum value. At this time, the nozzle assembly 3 is clamped within the clamping hole of the locking assembly 2. When the toggle member 202 rotates along the N direction to... Figure 8 In the lowered state shown, the distance between the first axis 7 and the second fixed support portion 2013b is at or near its minimum. Since the distance between the first axis 7 and the first fixed support portion 2013a in the second direction is fixed, the distance between the first fixed support portion 2013a and the second fixed support portion 2013b in the second direction is at or near its maximum. That is, the width W1 of the opening 2012 in the second direction is at or near its maximum. At this time, the locking assembly 2 releases the nozzle assembly 3, and the user can remove the nozzle assembly 3 from the nozzle structure. It is understood that in other embodiments, the rotating support portion 2021 can also have other structures, as long as rotating the rotating support portion 2021 can squeeze or release the first fixed support portion 2013a in the second direction. This will not be elaborated here.

[0044] In this embodiment, the first axis 7 is perpendicular to the second direction, which not only facilitates the rotation of the knob 202 but also prevents interference between the knob 202 and other environmental components when rotating it, resulting in a more rational spatial layout and a simpler structure. For an example, please refer to... Figure 4 and Figure 6 As shown, the first axis 7 can be perpendicular to the first direction and the second direction. Alternatively, the first axis 7 can also be parallel to the first direction.

[0045] It should be noted that in other embodiments, the first axis 7 may be perpendicular to the second direction in other directions, or the first axis 7 may not be perpendicular to the second direction. It can be set according to the actual situation, which will not be elaborated here.

[0046] In one embodiment, the locking assembly 2 may further include a washer 203, which is disposed between the toggle member 202 and the clamping ring member 201. The washer 203 is fixed to the clamping ring member 201, and a second mating surface 20132 may be formed on the side of the washer facing the toggle member 202. The washer 203 effectively protects the clamping ring member 201, preventing it from being frequently damaged by friction after long-term use, thus extending its service life and reducing operating costs.

[0047] In some examples, the gasket 203 can be made of brass. The brass gasket 203 has good metal lubrication, which allows the knob 202 to withstand frequent friction during rotation, thus extending the service life of the knob 202 and reducing the cost of use.

[0048] In some examples, please refer to Figure 9As shown, the gasket 203 can be used as part of the first fixed support portion 2013a. Specifically, the first fixed support portion 2013a may include the gasket 203 and the body 20131, wherein the body 20131 is fixed to one side of the opening 2012, the gasket 203 is detachably connected to the body 20131, and the gasket 203 is placed between the body 20131 and the body 20131. When the gasket 203 is frequently damaged by friction, the gasket 203 can be replaced, without replacing the entire clamping ring 201, thus reducing the cost of use.

[0049] As an example, please refer to Figure 3 As shown, the surface of the gasket 203 facing the rotating support portion 2021, which is the second mating surface 20132, can be constructed as an arc-shaped surface. The arc-shaped second mating surface 20132 can effectively increase the contact area between the gasket 203 and the rotating support portion 2021, making the force on the rotating support portion 2021 and the gasket 203 more even and distributed, and further extending the service life of the overall structure.

[0050] As an example, the gasket 203 can be partially embedded in the body 20131. The body 20131 has an embedding recess 201311 that cooperates with the gasket 203, thereby improving the connection stability between the gasket 203 and the body 20131, preventing the gasket 203 from moving relative to the body 20131, and improving the stability of the overall structure.

[0051] In one embodiment, the knob 202 also includes a handle 2022, which protrudes circumferentially from the rotating support portion 2021. By turning the handle 2022, the user can rotate the rotating support portion 2021, enabling quick installation and removal with a single turn, making it convenient to use. In other embodiments, the handle 2022 can also be fixed to other positions on the rotating support portion 2021, depending on the actual situation, which will not be elaborated here.

[0052] As one implementation method, please refer to Figures 1 to 4 ,as well as Figures 6 to 9As shown, the locking assembly 2 also includes a first connector 204. The first connector 204 includes a first rod portion 2041 and a first flange portion 2042. The first rod portion 2041 extends along a second direction, and the first flange portion 2042 is formed at one end of the first rod portion 2041 in the second direction. The other end of the first rod portion 2041 in the second direction passes through the second fixed abutment portion 2013b and the first fixed abutment portion 2013a in sequence and is then connected to the rotating abutment portion 2021. The end of the second fixed abutment portion 2013b facing away from the first fixed abutment portion 2013a in the second direction abuts against the first flange portion 2042. The rotating abutment portion 2021 is rotatable relative to the first rod portion 2041 about a first axis 7, and the rotating abutment portion 2021 is rotatably connected to the clamping ring 201 via the first connector 204.

[0053] In this embodiment, the rotating abutment 2021 is rotatably connected to one end of the first rod 2041 in the second direction. The other end of the first rod 2041 in the second direction has a first flange 2042. The end of the second fixed abutment 2013b that is away from the first fixed abutment 2013a in the second direction abuts against the first flange 2042, thereby effectively limiting the distance between the first axis 7 and the second fixed abutment 2013b and ensuring the stability of the overall structure.

[0054] In one embodiment, the rotating support portion 2021 has a first mounting hole 20212, with the first axis 7 as its axis. The rotating support portion 2021 also has a clearance groove 20213, which surrounds the first axis 7 and communicates with the first mounting hole 20212. The locking assembly 2 further includes a second connector 205, which passes through the first mounting hole 20212. The first rod portion 2041 of the first connector 204 passes through the clearance groove 20213 and is fixed to the second connector 205. When the toggle member 202 rotates around the first axis 7, the second connector 205 remains stationary under the action of the first connector 204. That is, the toggle member 202 and the second connector 205 are rotatably connected, and the toggle member 202 can rotate relative to the second connector 205 around the first axis 7.

[0055] In one implementation, the second connector 205 is detachably fixed to the first connector 204. After a single part in the locking assembly 2 wears out, the first connector 204 can be disassembled, making it easy to replace the damaged part, extending the service life of the nozzle module and reducing the cost of use.

[0056] In some examples, the second connector 205 and the first connector 204 are threaded together. The second connector 205 has a second mounting hole 2051, which is a threaded hole. The second mounting hole 2051 is located circumferentially on the second connector 205 and extends radially along the second connector 205. The first connector 204 is threadedly connected to the second mounting hole 2051, facilitating installation and disassembly and making it more convenient to use.

[0057] As an example, the second connector 205 also has a third mounting hole 2052, which is a threaded hole. The third mounting hole 2052 is centered on the first axis 7 and communicates with the second mounting hole 2051. The locking assembly 2 also includes a fastener 206, which is threaded into the third mounting hole 2052 and can abut against the first connector 204 connected to the second mounting hole 2051. During assembly, the first connector 204 can be screwed into the second mounting hole 2051 of the second connector 205 first, and the first connector 204 can be inserted into or pass through the third mounting hole 2052. Then, the fastener 206 is screwed into the third mounting hole 2052 until the end of the fastener 206 abuts against the outer periphery of the first connector 204. Fastener 206 can effectively fix the first connector 204 and the second connector 205, preventing relative rotation of the first connector 204 and the second connector 205 after long-term use, thereby improving the stability and assembly reliability of the nozzle module.

[0058] In other implementations, please refer to Figures 10 to 26 In the illustrated embodiment, the toggle member 202 includes two rotating abutment portions 2021, which are spaced apart in a second direction. Two fixed abutment portions 2013 are located between the two rotating abutment portions 2021, and at least one of the two rotating abutment portions 2021 can press or release the corresponding fixed abutment portion 2013 in the second direction, so that the two fixed abutment portions 2013 move closer or further apart in the second direction.

[0059] As an example, please refer to Figure 16The two rotating abutment parts 2021 can remain relatively fixed, that is, the two rotating abutment parts 2021 rotate synchronously. The two rotating abutment parts 2021 can simultaneously squeeze or release the corresponding fixed abutment parts 2013, thereby causing the two fixed abutment parts 2013 to move closer or further apart along the second direction. Specifically, when the toggle member 202 rotates along the S direction, the two rotating abutment parts 2021 can simultaneously squeeze the corresponding fixed abutment parts 2013, causing the two fixed abutment parts 2013 to move towards each other in the second direction, thereby reducing the width W1 of the opening 2012 and the diameter of the clamping hole 2011, so that the clamping ring member 201 can clamp the nozzle assembly 3. When the toggle member 202 rotates in the N direction, the two rotating support parts 2021 can simultaneously release the corresponding fixed support parts 2013, so that the two fixed support parts 2013 can move backward in the second direction to increase the width W1 of the opening 2012 in the second direction, thereby allowing the clamping ring member 201 to release the nozzle assembly 3, which is convenient for operation and can effectively achieve quick installation and quick disassembly.

[0060] As one implementation method, please refer to Figures 17 to 26 As shown, the first mating surface 20211 is a wedge-shaped surface. The first mating surface 20211 faces the corresponding second mating surface 20132 in the second direction and is arranged around the second axis 8, wherein the second axis 8 is parallel to the second direction, and the first mating surface 20211 also extends obliquely in the second direction. The second mating surface 20132 faces the corresponding first mating surface 20211 in the second direction and is arranged around the second axis 8, extending obliquely in the second direction.

[0061] In this embodiment, when the knob 202 is in the lowered state, point a of the first mating surface 20211 abuts against point b of the second mating surface 20132. Please refer to [reference needed]. Figure 19As shown, at this time, the combined width W2 of the rotating abutment 2021 and the fixed abutment 2013 in the second direction is at its minimum or close to its minimum, while the width W1 of the opening 2012 in the second direction is at its maximum or close to its maximum. During the rotation of the torsion member 202 along the S-direction, point a of the first mating surface 20211 gradually moves away from point b, and the height difference between points a and b in the second direction increases, causing the combined width W2 of the rotating abutment 2021 and the fixed abutment 2013 in the second direction to increase. Since the relative positions of the two rotating abutment parts 2021 of the torsion member 202 are fixed, that is, the distance between the two rotating abutment parts 2021 in the second direction is fixed, the width W1 of the opening 2012 in the second direction decreases during the rotation of the torsion member 202 along the S-direction. When the toggle element 202 is in the up position, the height difference between points a and b in the second direction reaches its maximum value or is close to its maximum value. The combined width W2 of the rotating support part 2021 and the fixed support part 2013 in the second direction also reaches its maximum value or is close to its maximum value. Please refer to [reference needed]. Figure 20 As shown, the width W1 of the opening 2012 in the second direction is at or near its minimum. Therefore, when the toggle member 202 rotates around the S direction, the first mating surface 20211 can press against the corresponding second mating surface 20132, causing the two fixed abutments 2013 to move towards each other in the second direction, thereby reducing the width W1 of the opening 2012 in the second direction, and allowing the clamping ring member 201 to clamp the nozzle assembly 3. When the toggle member 202 rotates around the N direction, the first mating surface 20211 can release the corresponding second mating surface 20132, allowing the two fixed abutments 2013 to move away from each other in the second direction, thereby increasing the width W1 of the opening 2012 in the second direction, and allowing the clamping ring member 201 to release the nozzle assembly 3.

[0062] As an example, please refer to Figure 17 , Figure 18 ,as well as Figures 21 to 26 As shown, the rotating abutment part 2021 may have multiple first mating surfaces 20211, all of which are arranged around the second axis 8, and adjacent first mating surfaces 20211 are connected by a first transition surface 20214. Correspondingly, the fixed abutment part 2013 may have multiple second mating surfaces 20132, all of which are arranged around the second axis 8, and adjacent second mating surfaces 20132 are connected by a second transition surface 20133. The number of first mating surfaces 20211 and second mating surfaces 20132 is the same. Furthermore, the first mating surfaces 20211 and second mating surfaces 20132 are arranged in a one-to-one correspondence.

[0063] In this example, the rotating support portion 2021 has multiple first mating surfaces 20211, and the fixed support portion 2013 has a corresponding number of second mating surfaces 20132, with the first mating surfaces 20211 and the corresponding second mating surfaces 20132 abutting against each other. When the torsion member 202 is rotated, the clamping ring member 201 experiences more uniform and stable force, and the nozzle assembly 3 can be prevented from being pinched due to excessive rotation of the torsion member 202. In addition, the multiple first mating surfaces 20211 and second mating surfaces 20132 can effectively reduce the rotation angle of the torsion member 202 around the second axis 8, further improving the installation and disassembly efficiency and making operation easier.

[0064] The working principle of this example is as follows: when the torsion member 202 rotates along the S direction to the up position, the mating state of the first mating surface 20211 and the second mating surface 20132 is as follows. Figure 25 As shown, the height difference H between the first mating surface 20211 and the second mating surface 20132 in the second direction is at or near its maximum value. Since the relative positions of the two rotating abutment portions 2021 of the torsion member 202 are fixed, the width W1 of the opening 2012 in the second direction is at or near its minimum value. At this time, the nozzle assembly 3 is clamped in the clamping hole of the locking assembly 2. When the torsion member 202 rotates around the N direction to the lowered state, the mating state of the first mating surface 20211 and the second mating surface 20132 is as follows. Figure 26 As shown, the height difference H between the first mating surface 20211 and the second mating surface 20132 in the second direction is at or near the minimum value. For example, the height difference H can be zero. At this time, the width W1 of the opening 2012 in the second direction is at or near the maximum value. At this time, the locking component 2 releases the nozzle component 3, and the user can remove the nozzle component 3 from the nozzle structure.

[0065] In some examples, please refer to Figures 21 to 24 The rotating support part 2021 can have three first mating surfaces 20211, and correspondingly, the fixed support part 2013 can have three second mating surfaces 20132. This not only makes the structure simple and easy to manufacture, but also makes the clamping ring 201 more evenly and stably stressed, and effectively reduces the twisting angle of the twisting part 202.

[0066] It should be noted that in other embodiments, the rotating support part 2021 may also include one or other number of first mating surfaces 20211, and the fixed support part 2013 may also include one or other number of second mating surfaces 20132, which can be set according to the actual situation, and will not be described in detail here.

[0067] In some examples, please refer to Figure 22 , Figure 25 and Figure 26The first transition surface 20214 can be a plane parallel to the second axis 8. The second transition surface 20133 can be a plane parallel to the second direction. When the knob 202 rotates along the N direction until the first transition surface 20214 abuts against the corresponding second transition surface 20133, the knob 202 can no longer continue to rotate along the N direction. This effectively indicates to the user that the nozzle assembly 3 has been released, and the nozzle assembly 3 can be removed from the locking assembly 2 and the heat dissipation assembly 1, making it more convenient to use and improving the user experience.

[0068] As one implementation method, please refer to Figure 12 , Figure 17 , Figure 18 as well as Figure 24 As shown, the fixed support portion 2013 has a receiving hole 20134, which is centered on the second axis 8, and the opening of the receiving hole 20134 faces the corresponding rotating support portion 2021. A second mating surface 20132 is formed on the bottom surface of the receiving hole 20134. The rotating support portion 2021 is rotatably connected to the receiving hole 20134. When the torsion member 202 rotates relative to the locking assembly 2, the rotating support portion 2021 rotates within the receiving hole 20134.

[0069] In this embodiment, the rotating support part 2021 is housed within the fixed support part 2013, so that the rotating support part 2021 and the fixed support part 2013 can cooperate more stably and effectively.

[0070] As one implementation method, please refer to Figure 11 , Figure 16 and Figure 17 As shown, the toggle component 202 also includes two first connecting arms 2023 and one second connecting arm 2024. The two first connecting arms 2023 are spaced apart and symmetrically arranged in the second direction. One end of the second connecting arm 2024 is connected to one end of one of the first connecting arms 2023, and the other end of the second connecting arm 2024 is connected to one end of the other first connecting arm 2023. The other ends of the two first connecting arms 2023 are respectively fixed with rotating abutment portions 2021.

[0071] In this embodiment, the two first connecting arms 2023 are connected as one unit via the second connecting arm 2024, thereby effectively fixing the relative positions of the two rotating abutment parts 2021. In use, the second connecting arm 2024 can be used as a handle; rotating the second connecting arm 2024 synchronously rotates the two rotating abutment parts 2021, causing them to simultaneously press or release the corresponding fixed abutment parts 2013, thus clamping or releasing the nozzle assembly 3. This is convenient to use, allowing for quick installation and removal with a single twist, which not only facilitates operation but also improves loading and unloading efficiency. Furthermore, the connection of the two rotating abutment parts 2021 via the first connecting arm 2023 and the second connecting arm 2024 solves the problem of the twisting component 202 deflecting after long-term use, ensuring that the performance of the nozzle module remains unchanged even after long-term use.

[0072] In one embodiment, the locking assembly 2 further includes two third connectors 207, which are symmetrically arranged in the second direction. Each third connector 207 includes a second rod portion 2071 and a second flange portion 2072. The second rod portion 2071 is centered on the second axis 8. The second flange portion 2072 is formed at one end of the second rod portion 2071 in the second direction. The other end of the second rod portion 2071 in the second direction passes through a corresponding rotating abutment portion 2021, and the other end of the second rod portion 2071 in the second direction is fixed to a corresponding fixed abutment portion 2013. To prevent the rotating abutment portion 2021 from detaching from the third connector 207, the side of the rotating abutment portion 2021 facing away from the fixed abutment portion 2013 in the second direction abuts against the second flange portion 2072.

[0073] In this embodiment, the toggle member 202 is rotatably connected to the clamping ring member 201 via the third connector 207, wherein the toggle member 202 can rotate relative to the third connector 207, and the third connector 207 is fixed to the clamping ring member 201. This not only has a simple structure, but is also easy to install.

[0074] In one implementation, the third connector 207 can be detachably fixed to the clamping ring 201, thereby facilitating the removal of the locking assembly 2 and allowing for the individual replacement of damaged parts.

[0075] As an example, the third connector 207 can be threadedly connected to the clamping ring 201. Specifically, the outer periphery of the end of the second rod 2071 that is connected to the clamping ring 201 can be provided with external threads, and the fixed support portion 2013 can be provided with a threaded hole that mates with the external threads. The second rod 2071 is threadedly connected to the threaded hole, which facilitates loading and unloading and makes it more convenient to use.

[0076] It should be noted that the knob 202 and / or the third connector 207 can also be connected to the clamping ring 201 in other ways, which can be set according to the actual situation, and will not be elaborated here.

[0077] As one implementation method, please refer to Figure 17 and Figure 18 As shown, the rotating support portion 2021 can be a split structure. Specifically, the rotating support portion 2021 may include a first connecting portion 20215 and a first mating portion 20216, which are detachably fixed. Both the first mating portion 20215 and the first mating portion 20216 are rotatably inserted into the third connector 207. The first connecting portion 20215 is fixed to the corresponding first connecting arm 2023, and the first mating portion 20216 rotates synchronously with the first connecting portion 20215. A first mating surface 20211 and a first transition surface 20214 are formed on the first mating portion 20216. When long-term use causes wear on the first mating surface 20211 and / or the first transition surface 20214, the first mating portion 20216 can be replaced separately, reducing usage costs and extending the service life of the overall structure.

[0078] As an example, one of the first connecting part 20215 and the first mating part 20216 is provided with a first limiting protrusion, and the other of the first connecting part 20215 and the first mating part 20216 is provided with a first limiting recess. The first limiting protrusion and the first limiting recess are inserted and fitted together, which can effectively transmit torque, so that the first mating part 20216 can rotate synchronously with the first connecting part 20215, thereby improving the reliability of the overall structure.

[0079] In some examples, please refer to Figure 17 and Figure 18The first mating part 20216 may have at least two first limiting protrusions 202161 evenly distributed around the second axis 8 at one end away from the fixed abutment part 2013 in the second direction. Correspondingly, the first connecting part 20215 is provided with first limiting recesses 202151 that correspond one-to-one with the first limiting protrusions 202161. The first limiting protrusions 202161 are inserted into the corresponding first limiting recesses 202151. The first limiting protrusions 202161 and the first limiting recesses 202151 that are inserted and mated can make the first mating part 20216 rotate synchronously with the first connecting part 20215, the first connecting arm 2023 and the second connecting arm 2024, so that the first mating part 20216 will not rotate around the second axis 8 relative to the first connecting part 20215. Furthermore, the first mating part 20216 and the first connecting part 20215 are abutted between the fixed supporting part 2013 and the second flange part 2072 in the second direction, which can enable the effective connection between the first limiting protrusion 202161 and the first limiting recess 202151 and prevent the first limiting protrusion 202161 from disengaging from the first limiting recess 202151.

[0080] It should be noted that in other embodiments, the first connecting part 20215 and the first mating part 20216 can also be detachably fixedly connected in other ways. Alternatively, the rotating supporting part 2021 can also be an integral structure. The specific configuration can be determined according to actual conditions, and will not be elaborated upon here.

[0081] As one implementation method, please refer to Figure 17 and Figure 18 As shown, the fixing and supporting part 2013 can be a split structure. Specifically, the fixing and supporting part 2013 may include a second connecting part 20135 and a second mating part 20136, which are detachably fixed. Both the second connecting part 20135 and the second mating part 20136 pass through the third connecting member 207, and are relatively fixed to the third connecting member 207. The second connecting part 20135 is fixed to one side of the opening 2012, and a second mating surface 20132, a second transition surface 20133, and a receiving hole 20134 are formed in the second mating part 20136. When long-term use causes wear on the second mating surface 20132 and / or the second transition surface 20133, the second mating part 20136 can be replaced separately, reducing usage costs and extending the service life of the overall structure.

[0082] As an example, one of the second connecting part 20135 and the second mating part 20136 is provided with a second limiting protrusion, and the other of the second connecting part 20135 and the second mating part 20136 is provided with a second limiting recess. The second limiting protrusion and the second limiting recess are inserted and engaged, which can effectively fix the second mating part 20136 and prevent the second mating part 20136 from rotating with the first mating part 20216, thereby improving the reliability of the overall structure.

[0083] In some examples, please refer to Figure 17 and Figure 18 The second mating part 20136 may have a second limiting protrusion 201361 extending perpendicularly to the second axis 8 at one end opposite to the movable abutment part in the second direction. Correspondingly, the second connecting part 20135 has a second limiting recess 201351 that is inserted into and cooperates with the second limiting protrusion 201361. The insertion and cooperation of the second limiting protrusion 201361 and the second limiting recess 201351 can keep the second mating part 20136 and the second connecting part 20135 fixed, so that the second mating part 20136 will not rotate relative to the second connecting part 20135 about the second axis 8. Furthermore, the second connecting portion 20135 has a threaded hole that is threadedly connected to the second rod portion 2071. The second mating portion 20136 is abutted between the rotating supporting portion 2021 and the second connecting portion 20135, which can effectively connect the second limiting protrusion 201361 and the second limiting recess 201351, preventing the second limiting protrusion 201361 from disengaging from the second limiting recess 201351.

[0084] It should be noted that in other embodiments, the second connecting part 20135 and the second mating part 20136 can also be detachably and fixedly connected in other ways. Alternatively, the fixing and supporting part 2013 can also be an integral structure. The specific configuration can be determined according to actual conditions, and will not be elaborated upon here.

[0085] It should be noted that in other embodiments, the two rotating abutment parts 2021 can rotate simultaneously, but only one of the rotating abutment parts 2021 squeezes or releases the corresponding fixed abutment part 2013, while the other rotating abutment part 2021 does not squeeze or release the corresponding fixed abutment part 2013 when it rotates, thereby causing one of the fixed abutment parts 2013 to move closer to or further away from the other fixed abutment part 2013 in the second direction.

[0086] For example, only one pair of corresponding rotating abutment portions 2021 and fixed abutment portions 2013 may be provided with a first mating surface 20211 and a second mating surface 20132, while the other pair of corresponding rotating abutment portions 2021 and fixed abutment portions 2013 may not have a first mating surface 20211 and a second mating surface 20132. The surfaces of the other pair of corresponding rotating abutment portions 2021 and fixed abutment portions 2013 that abut against each other in the second direction are planes perpendicular to the second axis 8. In other words, the first mating surface 20211 and the second mating surface 20132 can be replaced with planes perpendicular to the second axis 8.

[0087] As an example, please refer to Figure 17 and Figure 18 As shown, the rotating support portion 2021 can be detachably fixed to the first connecting arm 2023. For example, the two are fixed by a threaded connection. Depending on actual needs, one pair of rotating support portions 2021 and fixed support portions 2013 having a first mating surface 20211 and a second mating surface 20132 can be replaced with rotating support portions 2021 and fixed support portions 2013 having a plane perpendicular to the second axis 8 as described above, which makes the use more flexible and can accommodate nozzle assemblies 3 with more diameter sizes.

[0088] Alternatively, in other embodiments, the two rotating abutment portions 2021 can rotate separately, and the rotating abutment portion 2021 will squeeze or release the corresponding fixed abutment portion 2013, thereby allowing the corresponding fixed abutment portion 2013 to move closer to or further away from the other fixed abutment portion 2013 in the second direction.

[0089] For example, it can remove Figures 1 to 9 The first flange portion 2042 in the embodiment shown, and the first connector 204 symmetrically connected to two ends in the second direction. Figures 1 to 9 In the embodiment shown, the two knobs 202 can be in a synchronized state, or one knob 202 can be in an up state while the other knob 202 is in a down state, thereby accommodating nozzle assemblies 3 with a wider range of diameters.

[0090] In some implementation methods, please refer to Figure 17 and Figure 18As shown, the clamping ring 201 also includes a ring portion 2014, which has a clamping hole 2011 and an opening 2012, meaning that two fixing abutments 2013 are fixed to the ring portion 2014. When the fixing abutments 2013 are of a split structure, the second connecting portion 20135 is fixed to the ring portion 2014. The clamping ring 201 also includes two fixing portions 2015, which are symmetrically arranged about the ring portion 2014. One end of each fixing portion 2015 is formed in the ring portion 2014, and the other end of each fixing portion 2015 extends circumferentially along the ring portion 2014. Furthermore, there is a gap between the fixing portion 2015 and the ring portion 2014, and the other end of the fixing portion 2015 is fixed to the heat dissipation assembly 1.

[0091] In this embodiment, a gap exists between the fixing part 2015 and the ring part 2014, which can effectively reduce the heat transfer from the nozzle assembly 3 to the heat dissipation assembly 1 via the locking assembly 2, thereby improving the heat insulation effect. Moreover, the fixing part 2015 extends circumferentially along the ring part 2014, which can effectively optimize the stress on the fixing part 2015, prevent the fixing part 2015 from breaking, and improve the product quality of the nozzle module.

[0092] In one embodiment, the fixing part 2015 can be detachably fixed to the heat dissipation assembly 1, thereby facilitating the individual replacement of parts and making installation and disassembly easier.

[0093] As an example, the heat dissipation assembly 1 is used to dissipate heat from the nozzle assembly 3, preventing the consumables inside the throat component 301 from melting and achieving smooth feeding. The heat dissipation assembly 1 includes a heat dissipation component 101, two heat insulation components 102, and two fixing components 103. The two heat insulation components 102 are symmetrically arranged on both sides of the heat dissipation component 101 in a second direction. The fixing components 103 are arranged one-to-one with the heat insulation components 102, and the fixing components 103 are sequentially inserted through the corresponding fixing part 2015 and the heat insulation component 102 along the first direction and fixed to the heat dissipation component 101. The nozzle assembly 3 passes through the heat dissipation component 101.

[0094] In this example, a heat insulation member 102 is provided between the fixing part 2015 and the heat sink 101, which can reduce the heat of the nozzle assembly 3 from being transferred from the fixing part 2015 to the heat sink 101 and improve the heat insulation effect.

[0095] In some examples, please refer to Figure 5 and Figure 15 As shown, the fastener 103 can be a threaded connector, for example, the fastener 103 can be a screw. The fastener 103 passes through the corresponding fixing part 2015 and the heat insulation part 102 in sequence and is threadedly connected to the heat dissipation part 101, which can not only effectively fix the locking assembly 2 to the heat dissipation assembly 1, but also facilitate installation and removal.

[0096] In some examples, the heat insulation element 102 can be made of nylon, thereby effectively blocking the transmission of heat. It should be noted that in other embodiments, the heat insulation element 102 can be made of other materials, which can be set according to the actual situation, and will not be elaborated here.

[0097] In some examples, heat sink 101 may include a heat sink fin.

[0098] In some implementation methods, please refer to Figure 5 , Figure 6 , Figure 13 , Figure 15 and Figure 18 As shown, the nozzle assembly 3 includes a throat component 301, a heat-conducting pipe component 302, a nozzle component 303, and a locking component 304. The throat component 301, the heat-conducting pipe component 302, and the nozzle component 303 are fixed sequentially in a first direction. The throat component 301 passes through the heat dissipation assembly 1. The locking component 304 is fixed to the outer periphery of the heat-conducting pipe component 302 and passes through the clamping hole 2011. That is to say, the locking assembly 2 is in direct contact with the locking component 304. During installation and removal, the locking assembly 2 directly clamps or loosens the locking component 304, thereby effectively protecting the heat-conducting pipe component 302.

[0099] As one implementation method, the locking fitting 304 is detachably fixed to the heat-conducting fitting 302. When the locking fitting 304 is damaged due to long-term use, the locking fitting 304 can be replaced separately, which extends the service life of the overall structure and reduces the cost of use.

[0100] As an example, please refer to Figure 28 As shown, the locking fitting 304 can be threaded to the heat-conducting fitting 302, which is not only simple in structure but also easy to install and remove.

[0101] In some examples, please refer to Figure 28 The locking tube 304 has a threaded hole that passes through the locking tube 304 in the first direction. Correspondingly, the outer periphery of the connection between the heat conduction tube 302 and the locking tube 304 has an external thread that mates with the threaded hole.

[0102] It should be noted that in other embodiments, the locking fitting 304 and the heat-conducting fitting 302 can also be connected and fixed in other ways, which can be set according to the actual situation, and will not be elaborated here.

[0103] As one implementation method, the heat-conducting pipe 302 and the nozzle 303 are interference-fitted, which improves the structural stability of the nozzle assembly 3.

[0104] In some examples, the heat pipe 302 can be made of copper, which has good thermal conductivity. It should be noted that in other embodiments, the heat pipe 302 can be made of other materials, which can be set according to the actual situation, and will not be elaborated here.

[0105] In one embodiment, the nozzle assembly 3 also includes a heat dissipation pipe 305, which is detachably fixed to the outer periphery of the throat pipe 301. The heat dissipation pipe 305 is disposed between the heat dissipation component 101 and the throat pipe 301, which can not only effectively protect the throat pipe 301 and solve the problem of damage to the throat pipe 301 after long-term use, but also ensure that the heat of the throat pipe 301 can be quickly dissipated through the heat dissipation component 101 because the heat dissipation pipe 305 is in close contact with both the heat dissipation component 101 and the throat pipe 301.

[0106] As an example, the heat dissipation pipe 305 is sleeved on the outer periphery of the throat pipe 301 along the first direction, and the heat dissipation pipe 305 and the throat pipe 301 are interference fit, which not only makes the connection more reliable, but also allows the heat of the throat pipe 301 to be transferred to the heat dissipation component 101 more quickly and effectively through the heat dissipation pipe 305.

[0107] In some examples, the heat sink 305 can be made of copper, which provides good heat dissipation. It should be noted that in other embodiments, the heat sink 305 can be made of other materials, which can be set according to the actual situation, and will not be elaborated here.

[0108] In some embodiments, the nozzle module further includes a heating assembly 4, which is sleeved outside the heat-conducting pipe 302. The heating assembly 4 is used to heat the consumable passing through the heat-conducting pipe 302, so that the nozzle 303 can extrude the molten consumable.

[0109] In one implementation, the heating component 4 is detachably fixed to the nozzle component 3. When the nozzle component 3 is quickly disassembled, the heating component 4 and the nozzle component 3 are disassembled as a whole. That is, the heating component 4 is separated from the nozzle module together with the nozzle component 3.

[0110] As an example, please refer to Figure 5 , Figure 6 , Figure 13 and Figure 15 As shown, the heat-conducting pipe 302 may include a pipe portion 3021 and a third flange portion 3022. The third flange portion 3022 protrudes circumferentially from the pipe portion 3021 and is located at one end of the pipe portion 3021 near the nozzle component 303. A locking pipe component 304 is threadedly connected to the end of the pipe portion 3021 away from the third flange portion 3022, thereby fixing the heating assembly 4 between the third flange portion 3022 and the locking pipe component 304.

[0111] In some embodiments, the heating assembly 4 includes a heating element 401. The heating element 401 is configured as a cylindrical structure fitted over the heat-conducting pipe 302, and is used to heat the heat-conducting pipe 302, thereby effectively heating the consumable to a molten state.

[0112] As an example, the heating element 401 can be an annular ceramic ring. Using an annular ceramic ring to heat the heat-conducting pipe 302 can not only achieve quick disassembly, but also make the heat transfer efficiency more efficient and the heat-conducting pipe 302 more uniformly heated, thus solving the problem of uneven heating of the nozzle assembly 3.

[0113] In one embodiment, the heating component 4 may also include a protective shell 402, which covers at least the heating element 401 to prevent heat leakage, thus ensuring not only the heating effect but also greater safety.

[0114] In one implementation, to better control the heating effect, the heating component 4 may also include a temperature sensor 403.

[0115] As an example, please refer to Figure 6 and Figure 13 As shown, a mounting hole 30221 can be provided on the third flange portion 3022. The temperature sensor 403 can be partially inserted into the mounting hole 30221, which not only facilitates installation but also allows for a more reasonable spatial layout and is more conducive to the miniaturization of the nozzle module.

[0116] The 3D printer described in this application includes the nozzle module provided in any of the above embodiments.

[0117] In this embodiment, the width W1 of the opening 2012 can be changed by rotating the knob 202, thereby changing the diameter of the clamping hole 2011. This allows the clamping ring 201 to clamp or release the nozzle assembly 3 passing through the clamping hole 2011, enabling quick installation and disassembly with a single twist. Furthermore, the installation and disassembly processes are simple and require no additional tools, improving installation and disassembly efficiency. Additionally, the locking component 2 reliably secures the nozzle assembly 3 to the heat dissipation component 1, solving the problem of the nozzle assembly 3 rotating and / or moving up and down during movement, thus achieving reliable fixation of the nozzle assembly 3.

[0118] In some implementation methods, the 3D printer also includes a base (not shown in the figure), and the heat sink 101 of the heat dissipation assembly 1 is connected to the base through a pressure acquisition device 5, which can acquire the pressure signal provided by the heat sink 101.

[0119] As an example, the pressure acquisition element 5 can be a strain gauge. The heat sink 101 and the pressure acquisition element 5 are fixedly connected by threaded connectors such as screws, and the pressure acquisition element 5 is fixed to the base by threaded connectors such as screws.

[0120] In some embodiments, the 3D printer also includes a limiting member 6. The heat dissipation assembly 1 is also connected to the base via the limiting member 6. The limiting member 6 and the pressure acquisition member 5 are respectively disposed at both ends of the heat dissipation assembly 1 in the first direction, thereby effectively preventing the nozzle module from shaking during high-speed movement.

[0121] As an optional implementation, the limiting member 6 can be threaded to the base, and the limiting member 6 is inserted into the heat sink 101 of the heat sink assembly 1 along the first direction, which not only facilitates installation, but also effectively restricts the heat sink assembly 1, making the heat sink assembly 1 more secure and stable to install.

[0122] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the 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.

[0123] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
