[0049] The structural parts of the printer shown, including the base 310, the rotating cover 320, and the unlocking device, are the objects of the action of the unlocking device and are the environmental features of the action of the unlocking device, rather than a part of the unlocking device itself; for the specific structure of this part, reference can be made to the prior art with the publication number CN116339093B. Figures 13 to 16

[0050] As shown in Figure 4 the lower end of the rotating member 110 is provided with a first relief groove 116, and the first relief groove 116 communicates with the second powder injection port; as shown in Figure 4 the second powder injection port on the rotating member 110 is actually a groove penetrating downward, and the downward penetrating part forms the first relief groove 116; when the unlocking device is inserted downward into the printer, the limiting portion can pass through the first relief groove 116 and enter the second powder injection port.

[0051] In this embodiment, "up" refers to the z direction in the figure, and "down" refers to the reverse direction of the z direction.

[0052] As shown in Figure 4 the rotating member 110 is provided with a pushing portion 113 at a position in front of the second powder injection port, and the pushing portion 113 is used to push the rotating cover 320 to rotate; wherein, a convex portion cooperating with the pushing portion 113 is provided on the inner wall of the rotating cover 320. After the unlocking device is inserted downward in place, the user rotates the rotating member 110 in the reverse direction of the a direction, and the rotating cover 320 can be rotated under the push of the pushing portion 113.

[0053] In this embodiment, "forward" refers to the positive direction along the rotation direction a, and "backward" refers to the reverse direction along the rotation direction a.

[0054] As shown in Figure 3 Figure 4 the bottom of the rotating member 110 is provided with a second limiting portion 115, and a through groove penetrating up and down is provided in the middle of the second limiting portion 115, and the unlocking mechanism 120 is arranged in the through groove; specifically, the second limiting portion 115 is provided with a through groove penetrating in the up and down direction, and the unlocking mechanism 120 is arranged in the through groove. At this time, the second limiting portion 115 can provide radial limitation for the unlocking mechanism 120.

[0055] Figure 3 As shown in Figure 3 ​As shown, a first axial limiting portion 121 is provided on the unlocking mechanism 120. The first axial limiting portion 121 is located above the bottom wall of the rotating member 110; 6. A second axial limiting portion 122 is provided on the unlocking mechanism 120. The second axial limiting portion 122 is located below the bottom wall of the rotating member 110; Specifically, the first axial limiting portion 121 is a convex ring provided on the unlocking mechanism 120, and the convex ring is located on the upper side of the bottom wall of the rotating member 110; the second axial limiting portion 122 is a convex ring protruding outward, and it abuts against the edge of the through groove that penetrates up and down opened by the second limiting portion 115; the two axial limiting portions provide axial limiting along the upper and lower directions.

[0056] As Figure 8 shown, a position limiting buckle 125 is further provided on the unlocking mechanism 120.

[0057] As Figures 7 to 9 shown, a second relief groove 126 is formed on the unlocking mechanism 120. The rotating member 110 can rotate to make the second relief groove 126 coincide with the first relief groove 116; when the unlocking device is inserted downward into the printer, both the first relief groove 116 and the second relief groove 126 can provide relief for the limiting portion, ensuring that the unlocking device can be inserted smoothly.

[0058] As Figures 9 to 11 shown, an unlocking portion 123 is provided at the bottom of the unlocking mechanism 120. The unlocking portion 123 can push the fixing member 340 to rotate so that the fixing member 340 and the positioning member 330 release the clamping of the locking protrusion; when the unlocking device is inserted downward into the printer, the unlocking portion 123 can push the fixing member 340 to rotate in the reverse direction of the rotation direction a, realizing the unlocking of the rotating cover 320.

[0059] Specifically, the length of the unlocking portion 123 protruding backward from top to bottom first increases and then decreases. As Figure 12 can be seen, the unlocking portion 123 is a structure protruding backward along the reverse direction of the rotation direction a, that is, the backward direction. The length of its backward protrusion first increases and then decreases from top to bottom. Therefore, the unlocking portion 123 looks like a triangle from the side view, having two inclined surfaces, an upper half and a lower half; this enables when the unlocking portion 123 is inserted into the printer, the inclined surface of the lower half pushes the first contact portion 341 to rotate in the reverse direction of the rotation direction a; and when the unlocking device is pulled out upward, the inclined surface of the upper half cooperates with the first contact portion 341, enabling the unlocking device to be pulled out smoothly, ensuring the smoothness of locking and unlocking.

[0060] As Figure 12 shown, there are multiple unlocking portions 123, and the multiple unlocking portions 123 are circumferentially distributed along the unlocking device; Refer to Figure 14The fixing member 340 has a plurality of mechanisms that can cooperate with the unlocking portion 123. Therefore, a plurality of unlocking portions 123 are provided on the unlocking portion 123, so that the unlocking mechanism 120 can better ensure the driving of the fixing member 340, and reduce the possibility of a single unlocking portion 123 being broken due to excessive force; Figure 11 , Figure 12 As shown, the unlocking mechanism 120 is further provided with an abutment portion 124 capable of cooperating with the second contact portion 342 at a position located inside the unlocking portion 123 . The abutment portion 124 can support the unlocking portion 123 on the inside to improve the unlocking stability.

[0061] The powder injection port unlocking device of this embodiment also includes:

[0062] The rotating component 110 is provided with a second powder injection port and a limiting groove 112, and the second powder injection port can be communicated with the outside;

[0063] The rotating component 110 can drive the rotating cover 320 to rotate, so that the second powder injection port, the first powder injection port and the powder injection channel 311 are connected, and the limiting portion is matched with the limiting groove 112 .

[0064] The unlocking device of the powder filling port of the above-mentioned printer is applied; when adding powder to the printer, the entire unlocking device can be inserted into the printer, so that the unlocking mechanism 120 releases the locking mechanism from the rotating cover 320; then the rotating component 110 is rotated relative to the unlocking mechanism 120, driving the rotating cover 320 to rotate together until the second powder filling port, the first powder filling port and the powder filling channel 311 are connected, and at the same time the limiting part cooperates with the limiting groove 112, at this time the powder filling channel 311 can be directly connected to the outside world, and a large amount of carbon powder can be continuously poured into the powder filling channel 311 from the second powder filling port; and the limiting part can limit the entire rotating component 110, effectively reducing the accident of the rotating component 110 escaping from the printer during the powder adding process, thereby improving safety.

[0065] Among them, one end of the limiting groove 112 is connected to the second powder injection port; the limiting part can directly slide into the limiting groove 112 from the second powder injection port. The specific use process is as follows:

[0066] 1. Insert the unlocking device downward into the printer, so that the unlocking portion 123 of the unlocking mechanism 120 pushes the fixing member 340 to rotate, thereby releasing the lock on the position of the rotating cover 320. During this process, the limiting portion will enter the second powder injection port through the first clearance groove 116 and the second clearance groove 126;

[0067] 2. Rotate the rotating component 110 in the opposite direction to direction a to push the rotating cover 320 to rotate, so that the second powder injection port, the first powder injection port and the powder injection channel 311 are connected, and the powder injection channel 311 is unlocked. During this process, the limiting part slides in the limiting groove 112;

[0068] 3. Powder is filled through the opening at the upper end of the rotating member 110. During this process, the cooperation between the limiting portion and the limiting groove 112 can prevent the unlocking device from coming out.

[0069] 4. Rotate the rotating member 110 along the a direction so that the limiting portion disengages from the limiting groove 112 and enters the second powder filling port, and then pull out the unlocking device upward.

[0070] In this embodiment, a sealing strip is provided on the inner side wall of the rotating member 110, and the sealing strip abuts against the unlocking mechanism 120. The sealing strip has two functions. The first is to abut against the unlocking mechanism 120 to ensure that the unlocking mechanism 120 is fixed relative to the rotating member 110 without external force. The second function is to reduce the toner leaking through the gap between the rotating member 110 and the unlocking mechanism 120 after the unlocking device unlocks the powder filling channel 311.

[0071] As Figure 5 shown, a handle portion 111 is also provided on the rotating member 110. After the unlocking device is inserted into the printer, the user can rotate the rotating member 110 by rotating the handle portion 111.

[0072] As Figures 6 to 8 shown, a position-limiting buckle 125 is provided on the unlocking mechanism 120, and a first limiting portion 114 is provided on the inner side wall of the rotating member 110. The rotating member 110 can be rotated until the position-limiting buckle 125 abuts against the first limiting portion 114. When the unlocking mechanism 120 rotates relative to the rotating member 110 along the a direction, the position-limiting buckle 125 can be rotated to abut against the first limiting portion 114, and at this time, the unlocking mechanism 120 cannot continue to rotate relative to the rotating member 110 along the a direction.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
