Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically a magnetic-free nozzle cover structure kit for a 3D printer. Background Technology

[0002] Currently, with the maturity of the 3D printing industry, various types of printers have emerged on the market, along with printheads of different structures. To facilitate quick maintenance of printheads during use, quick-release printhead covers were developed. Conventional quick-release printhead covers use a magnetic closure, but this structure can lead to increased gaps due to deformation, and the printhead cover can easily loosen during high-speed printing, accompanied by noise from the collision between the printhead cover and the printhead plate. Our new printhead structure, combining a pin and a spring clip, solves these structural problems such as noise caused by deformation and loosening during printing. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic-free nozzle cover structure kit for 3D printers to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetic-free nozzle cover structure kit for a 3D printer, comprising a main body, a nozzle plate mounted on the lower part of the main body, multiple nozzle backplate positioning holes mounted on the nozzle plate, an information connection cable mounted behind the nozzle backplate positioning holes, a heat sink mounted below the nozzle plate, a nozzle mounted below the heat sink, a turbine fan mounted on the right side of the heat sink, a fan guide mounted below the turbine fan, a housing mounted on the turbine fan, a base plate mounted on the housing, mounting holes mounted on the base plate, a fixing device mounted on the base plate, an air supply device mounted inside the housing, blades mounted on the outer side of the air supply device, a nozzle cover mounted on the right side of the turbine fan, an elastic male buckle mounted on the nozzle cover, an air guide port mounted below the elastic male buckle, multiple positioning pins mounted inside the nozzle cover, and a heat dissipation vent mounted on the nozzle cover.

[0005] Preferably, the printhead is detachable and can be replaced with printheads of different sizes, while the compact internal structure of the device can accommodate most printing printheads.

[0006] Preferably, the nozzle cover adopts an integrated molding process, requiring only one injection molding without any subsequent processes. At the same time, the use of an elastic male buckle design allows the nozzle cover to be directly installed, saving labor costs (manual installation of magnets) and magnet costs during production.

[0007] Preferably, the nozzle mask uses a snap-fit ​​connection, which makes its structure more stable. During normal use, there is no need to worry about the magnet falling off and causing malfunction.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. This 3D printer nozzle cover magnetic structure kit features a detachable nozzle design, allowing users to replace nozzles of different sizes to meet varying printing needs. The compact internal structure of the kit accommodates most printheads, improving nozzle versatility and ensuring stable performance under different printing environments and tasks. The nozzle cover is manufactured using a one-piece injection molding process, requiring no further processing. Its flexible snap-fit ​​design allows for direct installation, eliminating the need for manual magnet installation, saving both labor and magnet costs. The snap-fit ​​connection provides greater structural stability, preventing magnet loss and malfunctions during normal use. From nozzle detachability and internal structural adaptability to nozzle production efficiency and operational stability, this kit offers users a convenient and economical solution.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please refer to Figure 1This utility model provides a technical solution: a magnetic-free nozzle cover structure kit for a 3D printer, including a main body 1, a nozzle plate 2 installed below the main body 1, multiple nozzle backplate positioning holes 3 installed on the nozzle plate 2, an information connection cable 19 installed behind the nozzle backplate positioning holes 3, a heat sink 4 installed below the nozzle plate 2, a nozzle 5 installed below the heat sink 4, a turbine fan 6 installed on the right side of the heat sink 4, a fan guide 7 installed below the turbine fan 6, and a fan duct 7 mounted on the turbine fan 6. The device is equipped with a housing 15, a base plate 14 on the housing 15, mounting holes 9 on the base plate 14, a fixing device 13 on the base plate 14, an air supply device 12 inside the housing 15, blades 8 on the outside of the air supply device 12, a nozzle cover 10 on the right side of the turbine fan 6, a flexible male buckle 11 on the nozzle cover 10, an air guide 17 below the flexible male buckle 11, multiple positioning pins 18 inside the nozzle cover 10, and a heat dissipation vent 16 on the nozzle cover 10.

[0016] Among them, the printhead 5 is a detachable design and can be replaced with printheads of different sizes. At the same time, the compact internal structure of the device can accommodate the vast majority of printing printheads.

[0017] In this embodiment, printhead versatility is improved and performance is ensured to remain stable under different printing environments and tasks.

[0018] The nozzle mask 10 adopts an integrated molding process, requiring only one injection molding without any subsequent processes. At the same time, the design of the elastic male buckle 11 allows the nozzle mask 10 to be directly installed, saving labor costs during production, such as manual installation of magnets and magnet costs.

[0019] In this embodiment, the mask can be directly installed, which eliminates the step of manually installing magnets, saving labor costs during production, as well as magnet costs.

[0020] The nozzle mask 10 uses a snap-fit ​​connection, which makes its structure more stable. During normal use, there is no need to worry about the magnet falling off and causing malfunction.

[0021] In this embodiment, the buckle provides a more secure connection, reducing the likelihood of needing repair or replacement due to connection problems, thereby saving operating costs and extending the lifespan of the device.

[0022] Working principle: The positioning pin 18 on the nozzle cover 10 engages with the tapered positioning hole on the nozzle back plate 20 to achieve initial positioning. Simultaneously, the elastic male buckle 11 in the middle of the nozzle cover 10 engages with the female buckle on the nozzle back plate 20 through outward lateral tension, achieving precise positioning. At this point, the nozzle cover 10 is firmly fixed to the nozzle holder. When we need to remove the nozzle cover 10, we only need to press the elastic male buckle 11 on the nozzle cover 10 inward by hand, causing the elastic male buckle 11 to deform inward, thus disengaging from the control of the female buckle on the nozzle holder. The nozzle cover 10 can then be easily removed.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
