Abstract
Description
Technical Field
[0001] This invention relates to electronic imaging devices, and in particular to a toner cartridge with a toner outlet alignment mechanism. Background Technology
[0002] Most electronic imaging devices, such as photocopiers or office machines, have toner cartridges. When storing or transporting toner cartridges, their outlets must be sealed. When installing a toner cartridge in an electronic imaging device, the outlet of the toner cartridge must be aligned with the inlet of the electronic imaging device to allow toner to be input into the device. Since the inlet structures of different models of electronic imaging devices vary, a compatible toner cartridge must be designed to ensure that toner is successfully input from the cartridge into the device. Summary of the Invention
[0003] One objective of this invention is to provide a toner cartridge that, when assembled into an electronic imaging device and positioned, opens its originally closed toner outlet and connects to the toner inlet of the electronic imaging device to input toner into the electronic imaging device, thereby preventing toner leakage during assembly.
[0004] To achieve the above objectives, the toner cartridge of the present invention includes a cylindrical body, a base, a slide, a linkage, a swivel member, and a lifting member. The cylindrical body has an opening at one end. The base includes a cover fitted onto the opening, a toner outlet disposed on the cover, a first guide portion disposed on a first side of the cover, a second guide portion disposed on the first side of the cover and adjacent to the first guide portion, and a third guide portion disposed on a second side of the cover. The slide has a body slidably disposed on the base and a through hole in the body. The slide can move from a first position toward the cylindrical body to a second position. The position then moves to a third position and finally to a fourth position; the linkage is vertically and flexibly mounted on the slide block. When the slide block moves from the first position to the second position, the linkage is guided downward by the first guide part; the swivel member is pivotally mounted on the linkage. When the slide block moves from the second position to the third position, the swivel member is guided by the second guide part to swivel; the lifting member is vertically and flexibly mounted on the slide block. When the slide block moves from the second position to the fourth position, the lifting member is guided downward by the third guide part; when the slide block is in the fourth position, the toner outlet and the perforation are interconnected. Therefore, the toner cartridge of the present invention can open its originally closed toner outlet and connect with the toner inlet of the electronic imaging device when it is assembled into the electronic imaging device to allow toner to be input into the electronic imaging device, and can avoid toner leakage during assembly.

[0072] The technical content and features of the present invention will be described in detail below with reference to a preferred embodiment and accompanying drawings. Figures 1-5 As shown in Figures 1 and 10, a toner cartridge 1 provided in a preferred embodiment of the present invention is shown. The toner cartridge 1 includes a cylindrical body 2, a base 10, a slide 20, a linkage 30, a swivel member 40, a lifting member 50, and a cover 60.
[0073] The cylinder 2 is cylindrical and is used to contain carbon powder. It has an opening 4 at one end and an axial direction A.
[0074] The base 10 includes a cover 12 fitted onto the opening 4, a powder outlet 13 located on the bottom side of the cover 12, a first guide 14 located on the first side 121 of the cover 12, a second guide 15 located on the first side 121 of the cover 12 and adjacent to the first guide 14, a third guide 16 located on the second side 122 of the cover 12, two sliding joints 17 located on the lower left and right sides of the cover 12, two long grooves 18 located on the two sliding joints 17 respectively, and an upper sliding joint 19 located above the cover 12.
[0075] The cover 12 is round, and the powder outlet 13 is connected to the opening 4, such as... Figure 12 As shown, the first guide section 14 is a guide groove, which, in sequence towards the cylinder body 2, consists of a first initial horizontal section 141, a first downward inclined section 142, a first final horizontal section 143, and a first upward inclined section 144. The first final horizontal section 143 is positioned lower than the first initial horizontal section 141. Figure 8As shown, the second guide section 15 is also a guide groove and is located below the first guide section 14. Moving towards the cylinder body 2, it consists of a second initial horizontal section 151 approximately below the first downward inclined section 142, a second initial upward inclined section 152 approximately below the first final horizontal section 143, a second final horizontal section 153 approximately below the first final horizontal section 143, and a second final upward inclined section 154 approximately below the first upward inclined section 144. The second final horizontal section 153 is positioned higher than the second initial horizontal section 151. Figure 9 As shown, the third guide section 16 is also a guide groove, which consists of a third initial horizontal section 161, a third downward inclined section 162 and a third final horizontal section 163 in sequence towards the cylinder 2. The third final horizontal section 163 is lower than the third initial horizontal section 161. Here, "horizontal" means parallel to the axial direction A of the cylinder 2, not an absolute horizontal concept.
[0076] Additionally, a first sealing member 11 is provided on the bottom side of the base 10 corresponding to the position of the powder outlet 13. The first sealing member 11 has a central hole 111 corresponding to the powder outlet 13, such as... Figure 10 As shown. The base 10 is made of plastic, but the material is not limited. The first sealing element 11 is made of foam. The extension directions of the lower sliding part 17, the long groove 18 and the upper sliding part 19 are all parallel to the axial direction A.
[0077] like Figures 3-5 As shown in Figure 10, the slide block 20 has a body 21 slidably disposed on the base 10, a first sliding groove 22 located on the first side 211 of the body 21 and positioned opposite the first guide portion 14 and the second guide portion 15, a second sliding groove 23 located on the second side 212 of the body 21 and positioned opposite the third guide portion 16, two elastic arms 24 extending from the body 21, and a through hole 26 disposed on the body 21, wherein the ends of the two elastic arms 24 respectively point outward. An extension hook 25 extends through two elongated slots 18 of the base 10. The main body 21 is generally annular and slidably connected to the two sliding portions 17 and the upper sliding portion 19, allowing the slide block 20 to move along the axis A from a first position P1 to a second position P2, then to a third position P3, and finally to a fourth position P4. The first sliding groove 22 and the second sliding groove 23 extend vertically and are approximately perpendicular to the axis A. The slide block 20 is made of plastic, but the material is not limited.
[0078] The linkage 30 is vertically and flexibly disposed between the slide block 20 and the first guide portion 14. The linkage 30 has a first protrusion 32 extending into the first guide portion 14, a first crossbar 34 passing through the first slide groove 22, and a first head 36 located at the end of the first crossbar 34 and outside the first slide groove 22. The first protrusion 32 can move along the first guide portion 14, the first crossbar 34 can move along the first slide groove 22, and the first head 36 prevents the linkage 30 from laterally disengaging from the first slide groove 22. Thus, as... Figure 12 As shown, when the slide block 20 moves from the first position P1 to the second position P2, the first protrusion 32 moves from the first initial horizontal section 141 to the first downward inclined section 142, and the linkage 30 moves downward along the first slide groove 22 under the guidance of the first guide part 14; as Figure 15 As shown, when the slide block 20 moves from the second position P2 to the third position P3, the first protrusion 32 moves from the first downward inclined section 142 to the first final horizontal section 143, and the linkage 30 does not move; Figure 18 As shown, when the slide block 20 moves from the third position P3 to the fourth position P4, the first protrusion 32 moves from the first end horizontal section 143 to the first upper inclined section 144, and the linkage 30 is guided by the first guide part 14 to move upward along the first slide groove 22.
[0079] The gyratory member 40 is located between the slide block 20 and the first guide portion 14. The gyratory member has a second protrusion 42 that extends into the second guide portion 15, a second crossbar 44 pivotally mounted at the bottom end of the linkage 30, and a second head 46 located at the end of the second crossbar 44 and outside the first slide groove 22. The second protrusion 42 can move along the second guide portion 15, the second crossbar 44 can move along the first slide groove 22, and the second head 46 prevents the gyratory member 40 from laterally disengaging from the first slide groove 22. Thus, as... Figure 12 As shown, when the slide block 20 moves from the first position P1 to the second position P2, the second protrusion 42 enters the second initial horizontal section 151 while the oscillating member 40 does not oscillate; as Figure 15 As shown, when the slide block 20 moves from the second position P2 to the third position P3, the second protrusion 42 moves from the second initial horizontal section 151 to the second initial upward inclined section 152, and the oscillating member 40 is guided by the second guide part 15 and oscillates around the second crossbar 44 as an axis; Figure 18 As shown, when the slide block 20 moves from the third position P3 to the fourth position P4, the second protrusion 42 moves from the second final horizontal section 153 to the second final upward inclined section 154, and the oscillating member 40 moves upward together with the linkage 30.
[0080] The lifting member 50 is vertically and flexibly disposed between the slide block 20 and the third guide portion 16. The lifting member 50 has a third protrusion 52 extending into the third guide portion 16, a third crossbar 54 passing through the second slide groove 23, and a third head 56 located at the end of the third crossbar 54 and outside the second slide groove 23. The third protrusion 52 can move along the third guide portion 16, the third crossbar 54 can move along the second slide groove 23, and the third head 56 prevents the lifting member 50 from laterally disengaging from the second slide groove 23. Thus, as... Figure 13 As shown, when the slide block 20 moves from the first position P1 to the second position P2, the third protrusion 52 moves within the third initial horizontal segment 161, and the position of the lifting member 50 does not change; Figure 16 As shown, when the slide block 20 moves from the second position P2 to the third position P3, the third protrusion 52 moves from the third initial horizontal section 161 to the third downward inclined section 162, and the lifting member 50 moves downward along the second slide groove 23 guided by the third guide part 16; Figure 19 As shown, when the slide block 20 moves from the third position P3 to the fourth position P4, the third protrusion 52 continues to move in the third downward inclined section 162, and the lifting member 50 continues to move downward along the second slide groove 23 under the guidance of the third guide part 16.
[0081] The cover 60 is snapped together with the base 10, which can protect other internal components and make the structure of the base 10 (especially the sliding joint 17) more stable.
[0082] When the toner cartridge 1 is assembled into the electro-imaging device, the toner outlet 13 needs to overlap with a toner inlet 70 to facilitate the delivery of toner into the electro-imaging device. Figures 7-10 As shown, the toner outlet 13 is originally closed by the body 21 of the slide 20 located at the first position P1, while two pivotable and linked sealing doors 72 are provided next to the toner inlet 70 of the electronic imaging device to cover the toner inlet 70, which is advanced by the toner cartridge 1 (i.e., towards...). Figure 10 During the movement (in the direction of the arrow), the protrusion 25 extending from the long groove 18 will first embed into the recess 74 of the electronic imaging device, such as... Figure 6 As shown, this prevents the slide 20, along with the linkage 30, the swivel member 40, and the lifting member 50, from advancing along with the cylinder body 2 and the base 10. The continuing-advancing base 10, through its first guide 14, drives the linkage 30 and the swivel member downwards, while the lifting member 50 remains stationary. Figures 11-13As shown, when the slide block 20 reaches the second position P2, the swivel member 40 has moved downwards between the two sealing doors 72. When the base 10 further advances to the third position P3, the second guide part 15 drives the swivel member 40 to swivel and turn the sealing door 72 located in front forward. Since the two sealing doors 72 have a linkage structure (not shown), the sealing door 72 located behind also rotates backwards. At the same time, the third guide part 16 drives the lifting member 50 to move downwards to abut against the sealing door 72 located in front. Figures 14-16 As shown. When the toner cartridge 1 moves forward to the positioning position, the slide 20 moves relative to the base 10 to the fourth position P4. The third guide 16 drives the lifting member 50 to move further downward and presses down the front sealing door 72 further, while the rear sealing door 72 rotates backward simultaneously, so that the toner inlet 70 is fully opened. The first guide 14 drives the linkage 30 to move slightly upward, and the second guide 15 drives the swing member to move upward with the linkage 30 to avoid the front sealing door 72. Figures 17-20 As shown, at this time, the powder outlet 13, the perforation 26, and the powder inlet 70 are arranged from top to bottom and are correspondingly connected to each other. With the first sealing member 11 located between the base 10 and the slide 20, and the second sealing member 76 above the powder inlet 70 abutting against the bottom side of the slide 20, a sealed channel is formed, allowing the toner in the toner cartridge 1 to be smoothly transported to the electronic imaging device, and toner leakage during the assembly process can be avoided, thereby achieving the purpose of the present invention.
[0083] Based on the design spirit of this invention, the structure of the toner cartridge 1 can have other variations. For example, the first guide portion 14, the second guide portion 15, and the third guide portion 16 are not necessarily guide grooves or recesses, but can also be changed to convex portions, while the linkage 30, the oscillating member 40, and the lifting member 50 have matching recesses; the first sliding groove 22 allows other parts of the linkage 30 and the oscillating member 40 to extend into it, and the second sliding groove 23 allows other parts of the lifting member 50 to extend into it. All such easily conceivable structural variations should be covered by the scope of the patent application of this invention.
