Description

Technical Field

[0001] The invention relates to the technical field of printing consumables, in particular to a toner cartridge. Background Art

[0002] The toner cartridge includes a powder bin for storing toner, and the powder bin is provided with a rectangular powder bin opening. When working, the toner comes out of the powder bin opening to participate in development. Since the toner particles are very small, they are easy to leak during storage and transportation. At present, a sealing film is often used to stick it on the powder bin opening to seal the powder bin. In addition, when the user uses the toner cartridge, the sealing film must be pulled out from the sealing opening on one side of the powder bin. In addition, a sealing plug is provided at the sealing opening to prevent the toner from leaking out when the sealing film is pulled out. In the process of the sealing film being pulled out, the toner falling on the sealing film is eventually gathered at the sealing plug, thereby preventing the toner from leaking out. In order to prevent the sealing plug from being pulled out with excessive force during the process of pulling out the sealing film, a cover is added to the side wall of the powder bin by screws, and the cover prevents the sealing plug from being pulled out.

[0003] Therefore, it can be seen that the existing toner cartridges have the following defects: a cover that blocks the sealing plug is installed on the side wall of the powder bin by screws, and the structure is relatively scattered, which increases the installation process and mold costs; in addition, the position installation precision of the cover is high, and the thickness of the cover is relatively thin, which will lead to many problems such as the sealing film cannot be pulled out or the cover is torn or pulled off, and finally the entire toner cartridge is scrapped.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 3 , Figure 1 Schematic diagram of the overall structure of the toner cartridge in the first embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the powder bin after the sealing film is installed in the first embodiment of the present invention. Figure 3 It is a schematic structural diagram of a waste toner bin with a baffle protruding therefrom in Embodiment 1 of the present invention.

[0027] The invention provides a toner cartridge, belonging to the technical field of printing consumables. The toner cartridge has a compact structure, simplifies the installation process, reduces mold costs, avoids waste caused by leakage of toner resources, improves user experience, and ensures printing quality.

[0028] Specifically, see Figure 1-Figure 3The toner cartridge provided by the present invention comprises a powder bin 10 and a waste powder bin 20, wherein the powder bin 10 is provided with a powder bin opening, a sealing plug 12 is installed at the pull-opening end 11 of the powder bin opening to prevent leakage of toner, a long sealing film 13 penetrating the sealing plug 12 is sealed and pasted to the powder bin opening, and the free end of the long sealing film 13 is exposed outside the pull-opening end 11, and the user manually pulls the free end of the long sealing film 13 to pull out the long sealing film 13; a baffle 211 is convexly provided on the side wall 21 of the waste powder bin 20, and when the long sealing film 13 is pulled out, the baffle 211 can abut against the sealing plug 12 to prevent the sealing plug 12 from detaching from the pull-opening end 11.

[0029] In this embodiment, see Figure 1 The toner cartridge is provided with a baffle 211 protruding outward from the side wall 21 of the waste toner bin 20. The baffle 211 and the side wall 21 of the waste toner bin 20 are set as an integrated structure. The integrated injection molding makes the structure compact and simple, simplifies the installation process, and reduces the mold production cost; in addition, the baffle 211 can abut against the sealing plug 12 to prevent the sealing plug 12 from separating from the pull-mouth end 11, avoiding the waste of resources caused by the leakage of toner from the pull-mouth end 11 when the long sealing film 13 needs to be pulled out before the toner cartridge is used, thereby improving the user's use effect and ensuring the printing quality.

[0030] In this embodiment, see Figure 1 and Figure 2 The side wall 21 of the waste powder bin 20 is protruded with a baffle 211, which is arranged on the outer side of the pull-mouth end 11 and abuts against the sealing plug 12. Preferably, one end of the baffle 211 can be protruded upward to form an upper end, and the upper end of the baffle 211 is higher than the installation height of the long sealing film 13, or one end of the baffle 211 can be protruded downward to form a lower end, and the lower end of the baffle 211 is lower than the installation height of the long sealing film 13. The appropriate height improves the blocking degree of the baffle 211 to the sealing plug 12, and the upper end of the baffle 211 lifts the free end of the long sealing film 13, which is convenient for the subsequent pulling-out operation of the long sealing film 13.

[0031] In the present embodiment, further, the upper end of the baffle 211 is at least 1.5 mm higher than the installation height of the long sealing film 13. The setting of the appropriate size further ensures the blocking effect of the baffle 211 on the sealing plug 12, avoiding insufficient blocking strength due to too small a size, and avoiding obstruction of the long sealing film 13 from being pulled out due to too large a size.

[0032] In this embodiment, preferably, the thickness of the baffle 211 is set to at least 0.8 mm, which is generally the same thickness as the side wall 21 of the waste powder bin 20, and can preferably be thicker to ensure sufficient strength of the baffle 211 and strong bearing capacity to avoid breaking the baffle 211 due to excessive force when tearing the long strip sealing film 13.

[0033] In this embodiment, preferably refer to Figure 3 The upper end surface of the baffle 211 is arranged parallel to the long sealing film 13. Generally, the width of the baffle 211 is at least equal to the width of the long sealing film 13. Because the upper end of the baffle 211 is higher than the installation height of the long sealing film 13, the free end of the long sealing film 13 will be lifted by the upper end of the baffle 211. The above-mentioned parallel arrangement makes it convenient and smooth to pull out the long sealing film 13.

[0034] Embodiment 2:

[0035] See also Figure 4 and Figure 5 , Figure 4 is a schematic diagram of the overall structure of the toner cartridge in the second embodiment of the present invention, Figure 5 It is a schematic diagram of the structure of a powder bin provided with a baffle in the second embodiment of the present invention.

[0036] The difference between this embodiment and the above-mentioned embodiment 1 is that, see Figure 4 and Figure 5 The side wall 14 of the powder bin 10 is provided with a baffle 141 to replace the baffle 211 provided in the waste powder bin 20 in the first embodiment. The baffle 141 can abut against the sealing plug 12 to prevent the sealing plug 12 from being separated from the pull-opening end 11.

[0037] In the present embodiment, specifically, the side wall 14 of the powder bin 10 is provided with a baffle 141, which is square in shape. The baffle 141 is arranged on the outer side of the pull-mouth end 11 and abuts against the sealing plug 12. Preferably, one end of the baffle 141 may protrude upward to form an upper end, and the upper end of the baffle 141 is higher than the installation height of the long sealing film 13, or one end of the baffle 141 may protrude downward to form a lower end, and the lower end of the baffle 141 is lower than the installation height of the long sealing film 13. The appropriate height improves the degree of blocking of the sealing plug 12 by the baffle 141, and the upper end of the baffle 141 lifts the free end of the long sealing film 13, which is convenient for the subsequent pulling-out operation of the long sealing film 13.

[0038] In this embodiment, further preferably, the baffle 141 can be connected to the side wall 14 of the powder bin 10 by a snap-fit ​​connection to form an integrated structure. After the sealing plug 12 is installed to the pull-mouth end 11, the baffle 141 is installed to the side wall 14 of the powder bin 10 by a snap-fit ​​connection. The operation is simple and of course other structural settings are not limited.

[0039] In the present embodiment, the toner cartridge is provided with a baffle 141 protruding from the side wall 14 of the powder bin 10. The baffle 141 and the side wall 14 of the powder bin 10 are arranged as an integrated structure, which is compact and simple in structure and simplifies the installation process. In addition, the baffle 141 can abut against the sealing plug 12 to prevent the sealing plug 12 from detaching from the pull-mouth end 11, thereby avoiding the waste of resources caused by the leakage of toner from the pull-mouth end 11 when the long sealing film 13 needs to be pulled out before the toner cartridge is used, thereby improving the user's use effect and ensuring the printing quality.
