Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, and in particular to a novel toner capacity monitoring structure. Background Technology

[0002] In the field of printing consumables, accurate monitoring of toner capacity is crucial for ensuring print quality and user satisfaction. Currently, original toner cartridges typically incorporate a toner detection device within their toner compartment. This device often employs a localized conductive sheet structure, estimating the remaining toner level by measuring changes in capacitance between the toner and the conductive sheet. This design effectively monitors toner levels and is widely used in various printer models and compatible consumables.

[0003] However, existing toner detection structures have blind spots because their conductive sheets only cover a local area inside the toner cartridge. This makes it impossible to fully reflect the actual distribution and consumption status of the toner in the cartridge. Especially when using compatible toner, there is often a desynchronization phenomenon where the toner is exhausted but the chip still shows about 30% capacity remaining. This leads to users misjudging the toner status and making complaints, which seriously affects the user experience and product reputation.

[0004] Therefore, the inventors urgently need a new toner capacity monitoring structure that can achieve real-time synchronization between toner quantity and detection signal to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a novel toner capacity monitoring structure, aiming to solve the problem in the existing technology where the toner balance detection signal is not synchronized with the actual toner consumption due to the limited detection area of ​​the local conductive sheet.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a novel toner capacity monitoring structure, including a toner hopper body, a toner hopper sealing cover disposed on the opening side of the toner hopper body, and a conductive end cover disposed on one side of the toner hopper body. The inner bottom surface of the toner hopper body is an arc-shaped structure, and a conductive POM layer is integrally formed on the surface of the arc-shaped structure. The conductive POM layer is electrically connected to the conductive end cover.

[0007] Based on the above, the beneficial effect of a novel toner capacity monitoring structure is that it solves the problem in the existing technology where the toner balance detection signal is not synchronized with the actual toner consumption due to the limited detection area of ​​the local conductive sheet in the toner cartridge; this is mainly reflected in: 1. This utility model achieves real-time, blind-zone-free capacitance detection of carbon powder at various locations within the chamber by integrally forming a conductive POM layer on the surface of the arc structure. 2. This utility model forms a complete detection circuit by electrically connecting the conductive POM layer and the conductive end cap, thus realizing the stable transmission of toner status signals to the toner cartridge chip. 3. This utility model replaces the original local metal conductive sheet with a conductive POM layer integrally formed on the arc surface structure, which enhances the response to the consistency of toner distribution and realizes complete synchronization between the toner balance detection signal and the actual toner consumption.

[0008] Furthermore, the conductive end cap is provided with a conductive material, and the conductive POM layer is electrically connected to the toner cartridge chip through the conductive material.

[0009] Furthermore, the inner side of the powder hopper sealing cover is provided with a limiting rib, which is used to abut against the interior of the powder hopper body to limit the splicing position of the powder hopper sealing cover and the powder hopper body.

[0010] Based on the above, the beneficial effect of the limiting rib is to achieve rapid and accurate positioning of the powder hopper sealing cover and the powder hopper body during assembly and installation.

[0011] Furthermore, the limiting rib is one in number and is located in the middle of the powder hopper sealing cover.

[0012] Based on the above, the beneficial effect of the limiting rib located in the middle of the powder hopper sealing cover is that it greatly reduces the internal space occupied by the original multiple limiting ribs, thereby increasing the toner loading capacity inside the powder hopper.

[0013] Furthermore, the height of the limiting rib is 10mm and the thickness is 2mm.

[0014] Furthermore, the powder hopper body is welded to the powder hopper sealing cover.

[0015] Furthermore, the powder hopper body and the powder hopper sealing cover together constitute a powder hopper for containing toner.

[0016] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0018] The reference numerals in the attached figures are as follows: 1-Powder hopper body, 2-Powder hopper sealing cover, 21-Limiting rib, 3-Arc-shaped structure, 4-Conductive POM layer, 5-Conductive end cap, 51-Conductive material. Detailed Implementation

[0019] like Figures 1-3 As shown, a novel toner capacity monitoring structure includes a toner hopper body 1, a toner hopper sealing cover 2 disposed on the opening side of the toner hopper body 1, and a conductive end cover disposed on one side of the toner hopper body 1. The inner bottom surface of the toner hopper body 1 is an arc-shaped structure 3, and a conductive POM layer 4 is integrally formed on the surface of the arc-shaped structure 3. The conductive POM layer 4 is electrically connected to the conductive end cover 5.

[0020] The conductive end cap 5 is provided with a conductive material 51, and the conductive POM layer 4 is electrically connected to the toner cartridge chip through the conductive material 51.

[0021] The powder hopper sealing cover 2 is provided with a limiting rib 21 on its inner side. The limiting rib 21 is used to abut against the inside of the powder hopper body 1 to limit the splicing position of the powder hopper sealing cover 2 and the powder hopper body 1.

[0022] The limiting rib 21 is one in number and is located in the middle of the powder hopper sealing cover 2.

[0023] The height of the limiting rib 21 is 10mm and the thickness is 2mm.

[0024] The powder hopper body 1 is welded to the powder hopper sealing cover 2.

[0025] The powder hopper body 1 and the powder hopper sealing cover 2 together constitute a powder hopper for containing toner.

[0026] In summary, the specific embodiments of this utility model are as follows: The toner loaded in the toner cartridge body 1 gradually decreases as printing consumes it. Since the bottom surface of the toner cartridge body 1 is an arc-shaped structure 3 and its surface is integrally formed with a conductive POM layer 4, which fully covers the surface of the arc-shaped structure 3, the change in the remaining toner directly causes a change in the capacitance value between the conductive POM layer 4 and the toner. This changing electrical signal is continuously transmitted outward through the electrical connection between the conductive POM layer 4 and the conductive end cap 5, and is finally received and processed by the toner cartridge chip, thereby realizing real-time and blind-spot-free accurate monitoring of the toner capacity in the toner cartridge. During assembly, the powder hopper sealing cover 2 abuts against the interior of the powder hopper body 1 through the limiting ribs 21 set on its inner side, thereby quickly and accurately defining the splicing position of the two. Subsequently, the powder hopper body 1 and the powder hopper sealing cover 2 are fixedly connected by welding, together forming a complete sealed powder hopper for containing toner, providing a stable and reliable structural foundation for toner capacity monitoring.

[0027] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
