Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a printer toner cartridge device that is easy to disassemble. Background Technology

[0002] A toner cartridge, also known as a photosensitive drum, is generally composed of an aluminum base material and a photosensitive material coated on the base material. The toner cartridge is a core component of a laser printer and also a consumable part of the printer, with a limited lifespan. The toner cartridge is the component used to hold the toner. Structurally, toner cartridges are divided into two types: integrated toner cartridges and separate toner cartridges. An integrated toner cartridge integrates the toner cartridge and the photosensitive drum into the same device.

[0003] As disclosed in the authorization announcement CN222653260U, a moisture-proof toner cartridge includes a cartridge body with multiple through holes at the upper end. A threaded tube is installed at the upper end of each through hole, and a vent canister is inserted into the through hole. A spring-loaded assembly is installed on the bottom wall of the vent canister, and a desiccant packet is placed at the upper end of the spring-loaded assembly. A pressure cap assembly acting on the desiccant packet is threadedly connected inside the threaded tube. The advantages of this invention are: the vent canister is inserted and rests on the through holes via an overlapping ring; simply unscrewing the pressure cap assembly allows the vent canister to be removed and placed, facilitating maintenance. When the desiccant packet needs to be replaced, simply unscrewing the pressure cap assembly causes the telescopic rod to extend under the spring's return action, pushing the upper end of the desiccant packet out of the vent canister. This eliminates the need for tools such as tweezers, making replacement convenient.

[0004] While the aforementioned patent facilitates the replacement of the desiccant pack, the use of threaded connections and frequent disassembly can cause thread wear, leading to a decrease in sealing performance and consequently affecting the moisture-proof effect. Utility Model Content

[0005] The purpose of this invention is to provide a printer toner cartridge device that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A printer toner cartridge device with easy disassembly includes a cartridge body 1, with several parallel annular retainers 2 fixedly connected to its top. An annular groove 3, communicating with the center of the annular retainers 2, is perforated through the top of the cartridge body 1. A drying mechanism is disposed inside the annular groove 3. The drying mechanism includes an annular boss 5 fixedly connected to the inner circumference of the annular retainers 2, and a mesh cylinder 6 vertically disposed inside the annular groove 3. The lower top surface of the mesh cylinder 6 contacts the upper surface of the annular boss 5. A vertical mesh plate 7 is fixedly connected to the center of the inner side of the mesh cylinder 6. Desiccant packets 8 are filled in the cavities on both sides of the mesh cylinder 6 and the mesh plate 7. The drying mechanism also includes vertical grooves 9 vertically formed on both sides of the inner wall of the mesh cylinder 6, and a mechanism for engaging with... The hanger 10 in the vertical groove 9 has a semi-circular support plate 11 fixedly connected to its bottom end. The bottom end of the desiccant pack 8 contacts the top end of the semi-circular support plate 11. The semi-circular support plate 11 supports the bottom of the desiccant pack 8 upwards. The sealing cover 4 is detachably set at the top end of the annular card seat 2. A locking mechanism is provided between the sealing cover 4 and the annular card seat 2. The locking mechanism includes several card heads 12 arranged circumferentially on the upper end of the annular card seat 2 and several clearance grooves 13 arranged circumferentially on the outer periphery of the sealing cover 4. The clearance grooves 13 match the card heads 12. A spring 14 is elastically connected between the bottom end of the sealing cover 4 and the upper end of the mesh cylinder 6. A flange 15 is fixedly connected to the top end of the middle part of the sealing cover 4.

[0026] In this embodiment, the locking mechanism between the sealing cover 4 and the annular card seat 2, along with the elastic pressing action of the spring 14, achieves the effect of quick disassembly and assembly while maintaining a stable seal, thus solving the problem of seal failure caused by easy wear in traditional threaded connection structures.

[0027] Furthermore, through the sliding guide cooperation between the hanger 10 and the vertical groove 9 on the inner wall of the mesh cylinder 6, and the automatic alignment and support of the semi-circular support plate 11 on the desiccant pack 8, the tool-free quick installation and positioning of the desiccant pack 8 is achieved.

[0028] Working principle: First, the mesh cylinder 6 is vertically placed inside the annular groove 3. Positioning and lifting are achieved through the contact and engagement between the top end face of the mesh cylinder 6 and the upper end face of the annular boss 5. Then, the desiccant packs 8 are placed in the cavities on both sides of the inner mesh plate 7 of the mesh cylinder 6, and supported and positioned by the semi-circular support plate 11 at the bottom of the hanger 10. By pinching the top of the hanger 10, the desiccant packs 8 are lowered along the guide track of the vertical groove 9, so that they are precisely constrained in the preset position inside the mesh cylinder 6. After the drying component assembly is completed, the spring 14 is placed on the receiving part at the upper end of the mesh cylinder 6, and then the spring seat at the lower end of the sealing cover 4 is aligned with the upper end of the spring 14 for pre-compression. At this time, the sealing cover 4 is kept in place. In the unlocked state, the outer peripheral clearance groove 13 and the clamp head 12 of the annular clamp seat 2 are kept axially aligned; vertical downward pressure is applied to move the sealing cover 4 axially along the annular clamp seat 2. During this process, slight left and right twisting adjustments are made to ensure that all clamp heads 12 pass through the corresponding clearance groove 13 synchronously; when the sealing cover 4 compresses the spring 14 to the preset stroke, the sealing cover 4 is rotated horizontally to cause the clearance groove 13 and the clamp head 12 to be circumferentially misaligned. At this time, the hook-shaped part of the clamp head 12 and the locking plane of the outer periphery of the sealing cover 4 form an axial limit. The restoring force of the spring 14 keeps the sealing cover 4 in a stable pressed state, and finally achieves the sealing fit between the top of the mesh cylinder 6 and the annular boss 5.
