The heater 2200 heats the airflow in the air duct 1000 to make the air nozzle 2100 send out hot air.

[0033] Further, the oven comprises a buckle assembly 3000 for connecting a first hanger and a second hanger, wherein the first hanger comprises the air duct 1000, and the second hanger comprises at least one of the air nozzle 2100 and the heater 2200. It can be understood that at least one of the air nozzle 2100 and the heater 2200 is detachably connected with the air duct 1000 through the buckle assembly 3000. Specifically, one end of the buckle assembly 3000 is fixedly arranged on the side wall of the air duct 1000, and the air nozzle 2100 or the heater 2200 is fixedly connected to the other end of the buckle assembly 3000.

[0034] In some embodiments, the air nozzle 2100 is detachably connected with the air duct 1000 through at least one buckle assembly 3000.

[0035] In some embodiments, the heater 2200 is detachably connected to the air duct 1000 by at least one buckle assembly 3000. Further, both ends of the heater 2200 are connected to the air duct 1000 by the buckle assembly 3000; or one end of the heater 2200 is connected to the air duct 1000 by the buckle assembly 3000, and the other end of the heater 2200 is connected to the air duct 1000 by other connection means.

[0036] In some embodiments, both the air nozzle 2100 and the heater 2200 are detachably connected to the air duct 1000 by at least one buckle assembly 3000.

[0037] It should be noted that the air nozzle 2100 and the heater 2200 are provided in at least one. In the case where the air nozzle 2100 and the heater 2200 are provided in multiple, the air nozzle 2100 and the heater 2200 are alternately arranged along the extension direction of the air duct 1000 on the lower side of the air duct 1000 to achieve uniform heating.

[0038] In some embodiments, the heater 2200 comprises an infrared heater or an electromagnetic heater.

[0039] The present application relates to an oven, which comprises an air duct 1000 and an air nozzle 2100, and the air nozzle 2100 is connected to the air duct 1000. Specifically, the air nozzle 2100 is located on the lower side of the air duct 1000, and the air nozzle 2100 is connected to the air duct 1000, and the air duct 1000 is externally connected to an air generator by a pipeline, so as to realize air supply from the air duct 1000 to the air nozzle 2100.

[0040] Further, the oven comprises a buckle assembly 3000, which is used to connect a first hanging piece and a second hanging piece, wherein the first hanging piece comprises the air duct 1000, and the second hanging piece comprises the air nozzle 2100. It can be understood that the air nozzle 2100 is detachably connected to the air duct 1000 by the buckle assembly 3000. Specifically, one end of the buckle assembly 3000 is fixedly arranged on the side wall of the air duct 1000, and the other end of the buckle assembly 3000 is fixedly connected to the air nozzle 2100.

[0041] It can be understood that the air nozzle 2100 is connected to the air duct 1000 by at least one buckle assembly 3000, so as to improve the connection strength of the air nozzle 2100 and the air duct 1000.

[0042] In some examples, both ends of the air nozzle 2100 are connected to the air duct 1000 by the buckle assembly 3000. In some other examples, one end of the air nozzle 2100 is connected to the air duct 1000 by the buckle assembly 3000, and the other end of the air nozzle 2100 is connected to the air duct 1000 by other connection means.

[0043] It should be noted that the air nozzles 2100 are provided at least one. In the case of multiple air nozzles 2100, the air nozzles 2100 are distributed along the extension direction of the air duct 1000 at the lower side of the air duct 1000.

[0044] It can be understood that if the oven is not provided with the heater 2200, but the air sent into the air duct 1000 is hot air, in this case, the air nozzles 2100 can also send hot air.

[0045] The other configurations and operations of the coating machine and the oven are recorded in the related art for those skilled in the art, and will not be described in detail here. The structure of the buckle assembly 3000 will be introduced below.

[0046] The buckle assembly 3000 comprises a buckle seat 3100, a buckle actuating part 3200 and a buckle connecting assembly. The buckle seat 3100 is used to connect a first hanging part. The buckle actuating part 3200 is arranged on the buckle seat 3100. The buckle actuating part 3200 is connected to a second hanging part through the buckle connecting assembly. Specifically, the buckle seat 3100 is arranged on the side wall of the air duct 1000. One end of the buckle connecting assembly is connected to the buckle actuating part 3200. The other end of the buckle connecting assembly is fixedly connected to the air nozzle or the heater.

[0047] Further, the buckle connecting assembly can be unlocked and separated, so as to realize the detachable connection between the second hanging part and the first hanging part. Specifically, the buckle connecting assembly comprises a hook 3301 and a ring 3302. One of the hook 3301 and the ring 3302 is arranged on the buckle actuating part 3200, and the other is arranged on the second hanging part. When the hook 3301 hooks the ring 3302, the second hanging part is connected to the first hanging part. When the hook 3301 is separated from the ring 3302, the buckle connecting assembly is unlocked.

[0048] It can be understood that according to the foregoing, the first hanging part is the air duct 1000 in the oven, the second hanging part is the air nozzle 2100 or the heater 2200 in the oven, and the buckle actuating part 3200 is connected to the air nozzle 2100 or the heater 2200 through the buckle connecting assembly. Specifically, one of the hook 3301 and the ring 3302 is arranged on the buckle actuating part 3200, and the other is arranged on the side wall of the air nozzle 2100 or the side wall of the heater 2200.

[0049] It should be noted that the user operates the buckle actuating part 3200, and then the buckle connecting assembly can be unlocked, and the second hanging part and the first hanging part can be separated. Specifically, the first end of the buckle actuating part 3200 is hinged to the buckle seat 3100. With the hinged position of the first end of the buckle actuating part 3200 and the buckle seat 3100 as the fulcrum, the user applies force to the second end of the buckle actuating part 3200, and then the buckle actuating part 3200 is pried downward. Then, the second end of the buckle actuating part 3200 can move away from the buckle seat 3100, the hook 3301 is separated from the hanging ring 3302, and the buckle connecting assembly is unlocked.

[0050] The accompanying drawings are incorporated into the present application Figure 4 and the accompanying drawings Figure 5 For example, the buckle actuating part 3200 is connected to the hanging ring 3302, and the hook 3301 is fixedly arranged on the side wall of the tuyere 2100 or the side wall of the heater 2200. When the user rotates the buckle actuating part 3200 outward, the second end of the buckle actuating part 3200 rotates in the arrow direction in the figure and moves away from the buckle seat 3100. The buckle actuating part 3200 drives the hanging ring 3302 to move downward, and then the hanging ring 3302 is separated from the hook 3301, thereby achieving the unlocking of the buckle connecting assembly. Figure 5

[0051] Since the tuyere 2100 or the heater 2200 is hung on the lower side of the air duct 1000 by the buckle assembly 3000, if an accidental falling accident occurs, the second end of the buckle actuating part 3200 may automatically move away from the buckle seat 3100, thereby causing the accident. To prevent the buckle actuating part 3200 from moving in this way, the buckle assembly 3000 further includes a falling prevention assembly in the present application, which is used to prevent the buckle connecting assembly from being unlocked due to an accident.

[0052] Specifically, the falling prevention assembly includes a limiting part 3401, which is used to abut against the side of the buckle actuating part 3200 away from the buckle seat 3100. It can be understood that the limiting part 3401 is used to limit the second end of the buckle actuating part 3200, so that the second end of the buckle actuating part 3200 cannot move away from the buckle seat 3100.

[0053] Further, the limiting part 3401 is movable, so that the limiting part 3401 can release the limitation on the buckle actuating part 3200. Specifically, under the operation of the user, the limiting part 3401 can move away from the buckle actuating part 3200, so that the limiting part 3401 releases the abutment against the buckle actuating part 3200. In order for the user to operate the buckle actuating part 3200, the buckle connecting assembly is manually disconnected.

[0054] ​In some embodiments, the anti-falling assembly includes an anti-falling mounting seat 3402 arranged on the side wall of the air duct 1000, and the anti-falling mounting seat 3402 is located above the buckle seat 3100. The limiting component 3401 is movably arranged on the anti-falling mounting seat 3402.

[0055] The anti-falling mounting seat 3402 is provided with side upright plates 3403 arranged at intervals, and the second end of the buckle pushing component 3200 is located between the two side upright plates 3403. The limiting component 3401 is arranged as a limiting rod, and the two ends of the limiting component 3401 are movably connected with the two side upright plates 3403, respectively. The side of the limiting component 3401 abutting against the buckle pushing component 3200 away from the buckle seat 3100 can limit the second end of the buckle pushing component 3200 between the two side upright plates 3403.

[0056] Further, the two ends of the limiting component 3401 are movably arranged on the two side upright plates 3403, respectively, so that the limiting component 3401 can move away from the buckle pushing component 3200.

[0057] Specifically, the side upright plate 3403 is provided with an inclined sliding groove 3404, the guide direction of the sliding groove 3404 is inclined, and the lower end of the sliding groove 3404 gradually inclines from top to bottom and gradually approaches the position of the second end of the buckle pushing component 3200. One end of the limiting component 3401 is slidingly arranged in the sliding groove 3404 on one of the side upright plates 3403, and the other end of the limiting component 3401 is slidingly arranged in the sliding groove 3404 on the other side upright plate 3403. The limiting component 3401 can move along the sliding groove 3404 and approach or move away from the buckle pushing component 3200.

[0058] It should be noted that in the natural state, the limiting component 3401 can move along the sliding groove 3404 from top to bottom, and the limiting component 3401 gradually approaches the buckle pushing component 3200. When the limiting component 3401 moves to the lower end of the sliding groove 3404, the limiting component 3401 abuts against the side of the buckle pushing component 3200 away from the buckle seat 3100, thereby realizing the limitation of the limiting component 3401 to the buckle pushing component 3200.

[0059] It can be understood that, since the lower end of the sliding groove 3404 gradually inclines and extends, the limiting component 3401 can remain at the position of the bottom end of the sliding groove 3404 under the action of its own gravity, so that the limiting component 3401 remains abutting against the buckle pushing component 3200. Even if an accidental falling accident occurs, the buckle pushing component 3200 cannot automatically push the limiting component 3401 upward along the sliding groove 3404.

[0060] In some examples, the sliding groove 3404 extends along an arc-shaped trajectory.

[0061] Regarding the arrangement of the chute 3404, at least the following alternative example can exist: the chute 3404 extends along an inclined straight trajectory.

[0062] In some examples, the anti-falling mounting base 3402 and the buckle seat 3100 are arranged as two separate structures, and the anti-falling mounting base 3402 and the buckle seat 3100 are both fixedly arranged on the side wall of the air duct 1000. Further, the anti-falling mounting base 3402 is arranged as a sheet metal part, and both ends of the anti-falling mounting base 3402 are bent to form side standing plates 3403.

[0063] Regarding the anti-falling mounting base 3402 and the buckle seat 3100, at least the following alternative embodiments exist.

[0064] In some alternative embodiments, the anti-falling mounting base 3402 is fixedly connected with the buckle seat 3100.

[0065] In other alternative embodiments, the anti-falling mounting base 3402 is integrally formed with the buckle seat 3100. Specifically, the anti-falling mounting base 3402 and the buckle seat 3100 are integrally formed as a combined structure of a sheet metal part.

[0066] In some embodiments, the second end of the buckle actuating part 3200 is provided with a protrusion 3201 facing away from the buckle seat 3100, and the limiting part 3401 abuts the position on the buckle actuating part 3200 where the protrusion 3201 is located, so as to enhance the anti-falling effect of the limiting part 3401.

[0067] It should be noted that the protrusion 3201 arranged on the buckle actuating part 3200 can also facilitate the user to exert force to rotate the buckle actuating part 3200.

[0068] In some examples, on the second end of the buckle actuating part 3200, the protrusion 3201 is bent in a direction away from the buckle seat 3100, and the protrusion 3201 is formed as a bent section. Further, the limiting part 3401 is used to abut the side of the protrusion 3201 facing away from the buckle seat 3100, or the limiting part 3401 is used to abut the corner formed on the buckle actuating part 3200 by the protrusion 3201.

[0069] It can be understood that, since the protrusion 3201 is bent in a direction away from the buckle seat 3100, the side of the protrusion 3201 facing away from the buckle seat 3100 is formed as an inclined downward surface. In this case, when the side of the protrusion 3201 abuts the limiting part 3401, the limiting part 3401 provides an inclined upward resistance to the protrusion 3201, thereby preventing the second end of the buckle actuating part 3200 from rotating in a direction away from the buckle seat 3100.

[0070] On the other hand, when the protrusion 3201 exerts a force on the limiting part 3401, the side wall of the lower end of the chute 3404 exerts a reaction force on the limiting part 3401, and further clamps the limiting part 3401 at the lower end of the chute 3404, and the combined force of the chute 3404 and the protrusion 3201 further enhances the limitation of the limiting part 3401 on the buckle actuating part 3200.

[0071] It should be noted that in the examples in which the anti-falling mounting seat 3402 and the buckle seat 3100 are fixedly connected or are two separate structures, when an accidental falling occurs, the buckle seat 3100 may fall off the side wall of the air duct 1000, and the anti-falling mounting seat 3402 remains fixed on the side wall of the air duct 1000. In this case, since the limiting part 3401 abuts against the side of the protrusion 3201, the limiting part 3401 can prevent the buckle seat 3100 from moving downward with the buckle actuating part 3200, thereby preventing the air nozzle 2100 or the heater 2200 from falling.

[0072] The buckle assembly includes a buckle seat, a buckle actuating part, and a buckle connection assembly that can be unlocked, and the structures of the buckle seat, the buckle actuating part, and the buckle connection assembly are as described above.

[0073] The buckle assembly includes an anti-falling mounting seat arranged on the first hanging part. Specifically, the anti-falling mounting seat is arranged on the side wall of the air duct, is located above the buckle seat, and is provided with an anti-falling structure. The anti-falling structure is used to abut against the side of the buckle actuating part that faces away from the buckle seat, thereby preventing the second end of the buckle actuating part from moving away from the buckle seat.

[0074] Further, if the anti-falling structure is pressed, the abutment against the buckle actuating part can be released. In the case where the anti-falling structure abuts against and clamps the buckle actuating part, if the user pries the second end of the buckle actuating part outward, the anti-falling structure is subjected to a pressing force from the buckle actuating part, the anti-falling structure is displaced, and further avoids the buckle actuating part, so that the second end of the buckle actuating part can be rotated away from the buckle seat.

[0075] Specifically, the anti-falling mounting seat is provided with spaced-apart side upright plates, and the second end of the buckle actuating part is located between the two side upright plates. The opposite side walls of the two side upright plates are each provided with an anti-falling structure that protrudes from the side wall of the side upright plate. It can be understood that the anti-falling structure can limit the second end of the buckle actuating part between the two side upright plates.

[0076] When the user rotates the buckle actuating part, under the action of the user's force, the buckle actuating part will simultaneously exert a pressing force on the anti-falling structure when it contacts the anti-falling structure, and further cause the side upright plate to be pressed and tilted, so that the anti-falling structure is displaced and avoids the buckle actuating part.

[0077] It should be noted that the anti-falling mounting seat and the buckle seat are provided as two separate structures, or the anti-falling mounting seat and the buckle seat are fixedly connected, or the anti-falling mounting seat and the buckle seat are integrally formed.

[0078] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art in the technical field without departing from the purpose of the application. In addition, the embodiments of the application and the features in the embodiments can be combined with each other without conflict.
