[0043] FIG. 2 is a structurally schematic diagram of the compressed sealing cotton piece 2. The compressed sealing cotton piece 2 has a shape similar to a triangle, while a circumference thereof is smooth arc-shaped. The compressed sealing cotton piece has a first toner discharge hole 2-1 and an axial hole 2-2. The compressed sealing cotton piece 2 is installed under the base 1, the first toner discharge hole 2-1 is aligned with the toner outlet 1-7, and the second column 1-6 is inserted into the axial hole 2-2.

[0044] FIG. 3 is a structurally schematic diagram of the rotating block 3. The rotating block 3 also has a shape similar to a triangle.

[0045] Preferably, the compressed sealing cotton piece 2 is attached to the rotating block 3, and the rotating block 3 is located below the compressed sealing cotton piece 2 and then installed below the base 1. Preferably, the base 1 has a notch for accommodating the rotating block 3. The shape of the compressed sealing cotton piece 2 is preferably the same as that of the rotating block 3. The first toner discharge hole 2-1 of the compressed sealing cotton piece 2 is coaxial with a toner discharge channel 3-1, which has a certain height, of the rotating block 3.

[0046] The rotating block 3 comprises a rotating block plate part 3-4. The toner discharge channel 3-1, a sliding positioning hole 3-2 and a connecting rod column 3-3 are provided on the rotating block plate part 3-4. The first toner discharge hole 2-1 is coaxial with the toner discharge channel 3-1, i.e., after the compressed sealing cotton piece 2 is installed, the toner discharge channel 3-1, the first toner discharge hole 2-1 and the toner outlet 1-7 are coaxial (referring to FIG. 12). The second column 1-6 passes through the axial hole 2-2 and the sliding positioning hole 3-2 to connect the rotating block 3 with the base 1, and the sliding positioning hole 3-2 is in sliding fit with the second column 1-6. The connecting rod column 3-3 passes through a rotating block hole 4-2 of a connecting rod 4 (referring to FIG. 4 and FIG. 16). The axial hole 2-2 is coaxial with the sliding positioning hole 3-2.

[0047] The rotating block 3 may also be other shapes, such as circular, fan-shaped and V-shaped, as shown in FIGS. 25-27, as long as the rotating block 3 is able to rotate, discharge toner and block toner. It should be noted that, as shown in FIG. 26, the rotating block plate part 3-4 is V-shaped, wherein the toner discharge channel 3-1 is provided on one branch of the rotating block plate part 3-4, and no hole is provided in the other branch so that the toner outlet 1-7 is blocked.

[0048] FIG. 4 is a structurally schematic diagram of the connecting rod 4. The connecting rod 4 has the rotating block hole 4-2 and a driving sliding plate hole 4-1 at two ends thereof, respectively. As mentioned above, the rotating block hole 4-2 is fitted rotatably with the connecting rod column 3-3 (referring to FIG. 16), and the driving sliding plate hole 4-1 is fitted rotatably with a third column 6-5 of the driving sliding plate 6 (referring to FIG. 6 and FIG. 18). In this way, when the driving sliding plate 6 slides left and right, the connecting rod 4 is driven to slide left and right for driving the rotating block 3 to swing forward and backward, so that the toner outlet 1-7 is switched between an open state and a closed state.

[0049] FIG. 5 is a structurally schematic diagram of one return spring 5. Two ends of each of the return springs 5 are fitted with the first spring holding plate 1-5 (referring to FIG. 1) at the bottom of the base 1 and a second spring holding plate 6-4 (referring to FIG. 6),respectively. FIG. 17 shows the return springs 5 after installation.

[0050] FIG. 6 is a structurally schematic diagram of the driving sliding plate 6. The driving sliding plate has two troughs 6-6 in a middle thereof. One end of each of the troughs 6-6 is provided with the second spring holding plate 6-4, and the second spring holding plate 6-4 cooperates with the first spring holding plate 1-5 so that each of the return springs 5 is compressed or extended therebetween. As shown in FIGS. 16-18, after the installation is completed, the driving sliding plate 6 is engaged with the base 1 in a manner of sliding. In one embodiment, the driving sliding plate 6 has a slide groove 6-1. One slide rail 1-3 of the base 1 is inserted into the slide groove 6-1 and is able to slide left and right. Alternatively, the slide rail may be provided on the driving sliding plate 6, and the slide groove may be provided on the base 1. The third column 6-5 of the driving sliding plate is fitted rotatably with the driving sliding plate hole 4-1 of the connecting rod 4, and the structure after installation is shown in FIG. 18. Preferably, two return springs 5, two second spring holding plates 6-4 and two first spring holding plates 1-5 are provided to increase the spring return force.

[0051] In this way, during the pushing process of the toner container, the driving sliding plate 6 is driven to move by the reverse force of the internal structure of the machine opposite to the pushing direction, the return springs 5 are compressed, the driving sliding plate 6 drives the connecting rod 4 to move, and the rotating block 3 rotates, so that the toner discharge channel 3-1 communicates with the toner outlet 1-7, thereby realizing toner discharging.

[0052] On the contrary, when the toner container is taken out from the machine, under an action of elastic force of the return springs 5, the driving sliding plate 6 is driven to pull the connecting rod 4 for rotating the rotating block 3, so that the toner discharge channel 3-1 does not communicate with the toner outlet 1-7, thereby closing the toner outlet of the toner container.

[0053] The present application has beneficial effects of smooth installation, protection of the internal installation structure of the machine, and automatic closing of the toner outlet upon removing the toner container from the machine. At the same time, the structure and shape are simple, the production process requirements are lower, and the failure rate is low.

[0054] Preferably, the switch device according to the present application further comprises a fixed cover plate 7. FIG. 7 is a structurally schematic diagram of the fixed cover plate 7. Multiples buckles 7-1 of the fixed cover plate 7 are engaged with multiple buckle holes 1-1 of the base 1, respectively. Multiple first columns 1-2 of the base 1 are inserted into multiple first insert holes 7-2 of the fixed cover plate 7, respectively. Six first columns and six first insert holes are shown in figures. The second column 1-6 of the base 1 is inserted into a second insert hole 7-4 of the fixed cover plate 7, and a pressing plane 7-5 is provided to level the base 1 and the fixed cover plate 7. Two second screw holes 7-6 of the fixed cover plate 7 are coupled with two first screw holes 1-4 of the base 1 through two self-tapping screws 8 shown in FIG. 8, respectively. The base 1 and the fixed cover plate 7 are coupled together, so that the rotating block 3 attached with the compressed sealing cotton piece 2 is able to be pressed on the base 1. In addition, the fixed cover plate 7 has a second toner discharge hole 7-3, which is coaxial with the toner outlet 1-7. FIG. 19 is an exploded view of the switch device according to this implementation. FIG. 20 is a structural diagram of the switch device according to the present application and the toner container after installation, and FIG. 21 is a cross-sectional view of FIG. 20.

[0055] FIG. 22 shows an exploded view of the switch device according to the present application and the toner container. FIG. 23 shows a structural view of the toner container and the machine without outer casing. During the installation process of the toner container in the machine, a driving sliding plate holding portion 9 gradually contacts two second holding portions 6-3 of the driving sliding plate 6. Through the reaction force, as the toner container continues to be pushed in, the driving sliding block 6 will move in a direction opposite to the direction of loading the toner container into the machine (the reverse direction of arrow F); and by cooperating with the driving sliding block 6, the connecting rod 4 simultaneously moves opposite to the direction of installing the toner container (the reverse direction of arrow F). Since the connecting rod 4 is slidingly fitted with the rotating block 3, and the rotating block 3 is rotatably fitted on the second column 1-6, the rotating block 3 is able to rotate. When the connecting rod 4 moves, the rotating block 3 begins to rotate under force. FIG. 9 shows the initial state of the rotating block. As the toner container is continuously loaded into the machine, the rotating block is gradually stressed and gradually rotates to the position shown in FIG. 10 under the traction of the connecting rod 4, and finally rotates to the state shown in FIG. 11. During this process, every return spring 5 is compressed to the lowest position by every second spring holding plate 6-4 and every first spring holding plate 1-5. During the above rotation process, the toner outlet of the toner container is gradually opened.

[0056] FIG. 12 shows the initial position of the rotating block 3. The toner outlet 1-7 is blocked by the rotating block plate part 3-4 of the rotating block 3 attached with the compressed sealing cotton piece 2. As the toner container is gradually installed into the machine, the rotating block 3 attached with the compressed sealing cotton piece 2 continues to rotate to the state shown in FIG. 13, and finally rotates to the state shown in FIG. 14, thereby realizing that the four holes, i.e., the toner outlet 1-7, the first toner discharge hole 2-1 of the compressed sealing cotton piece 2, the toner discharge channel 3-1 of the rotating block 3, and the second toner discharge hole 7-3 of the fixed cover plate 7, are coaxial with each other, so as to achieve a communication state. In this way, the toner inside the toner container is able to flow out through the toner port.

[0057] When the toner container is taken out from the machine, as shown in FIG. 24, the driving sliding plate holding portion 9 gradually separates from first holding portions 6-2 and second holding portions 6-3 of the driving sliding plate 6 of the machine, and every return spring 5 rebounds from the lowest position, caused by the compression of every second spring holding plate 6-4 and every first spring holding plate 1-5, to drive the driving sliding plate 6 and the connecting rod 4 to move in the direction of the elastic force of every return spring 5. The connecting rod 4 drives the rotating block 3 to rotate from the state of FIG. 14, through the state of FIG. 13, and finally to the state of FIG. 12, thereby realizing the closing function of the toner outlet 1-7.

[0058] The above-described embodiments are only preferred specific implementations of the present application. The phrases in one embodiment, in another embodiment, in yet another embodiment or in other embodiments mentioned in this specification may refer to one or more of the same or different embodiments according to the present disclosure. The usual changes and substitutions made by those skilled in the art within the scope of the technical solutions of the present application should be included in the protection scope of the present application.
