Description

Technical field

[0001] The utility model relates to the technical field of printing consumables equipment, in particular to a connection structure of a toner cartridge powder bin and a waste toner bin. [Background Technology]

[0002] In office equipment such as printers and copiers, toner cartridges, as core consumable components, are responsible for the important task of transferring images or text from electronic devices to paper media. The interior of the toner cartridge contains a powder hopper and a waste toner hopper. The powder hopper is responsible for storing and supplying toner, while the waste toner hopper is used to collect waste toner generated during the printing process. In existing toner cartridges, the connection structure between the powder hopper and the waste toner hopper is generally relatively complex. This is mainly reflected in the fact that there is a large-area snap-fit ​​structure between the powder hopper shell and the waste toner hopper shell. This snap-fit ​​structure generally also has multiple slots or holes that serve as a clearance for components such as the developing roller, photosensitive drum, and gears. This causes the snap-fit ​​structure between the powder hopper and the waste toner hopper to have many stress concentration points, making the overall strength of the snap-fit ​​structure relatively fragile. As a result, the powder hopper and the waste toner hopper are easily damaged due to careless operation during connection and assembly, thereby indirectly reducing the production efficiency of the product. Therefore, there is a need for a connection structure that can conveniently connect the powder hopper and the waste toner hopper during the assembly process of the toner cartridge. [Summary of the invention]

[0024] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to the attached Figure 1 To the attached Figure 5, this embodiment provides a connection structure between a toner cartridge powder bin and a waste powder bin, including a powder bin housing 1, a waste powder bin housing 2, and a connection assembly 3 provided between the powder bin housing 1 and the waste powder bin housing 2, the connection assembly 3 including a first snap mechanism 31 and a second snap mechanism 32 arranged opposite to each other, the first snap mechanism 31 including a first snap arm 311 and a first snap groove 312 arranged correspondingly, and a first latch 313 and a first latch opening 314 arranged between the first snap arm 311 and the first snap groove 312, the second snap mechanism 32 including a second snap arm 321 and a second snap groove 314 arranged correspondingly, The second clamping slot 322, and the second tenon 323 and the second clamping port 324 provided between the second clamping arm 321 and the second clamping slot 322; when the first clamping arm 311 is engaged with the first clamping slot 312, the first tenon 313 is clamped into the first clamping port 314 to connect and position one end of the powder bin shell 1 and the waste powder bin shell 2, and make the second clamping arm 321 face the second clamping slot 322; when the second clamping arm 321 is engaged with the second clamping slot 322, the second tenon 323 is clamped into the second clamping port 324 to connect and fix the powder bin shell 1 and the waste powder bin shell 2. The connection structure between the toner cartridge powder bin and the waste toner bin of this embodiment adopts the cooperation of the first snap mechanism 31 and the second snap mechanism 32, so as to achieve the effect of quick connection and fixation between the powder bin shell 1 and the waste toner bin shell 2 during the assembly of the toner cartridge. Specifically, in the first snap mechanism 31, the cooperation of the first latch 313 and the first bayonet 314 is adopted to achieve the locking of the first clamping arm 311 and the first clamping groove 312 after engagement, and at the same time, the engagement of the second clamping arm 321 and the second clamping groove 322 has the effect of pre-positioning; In the snap mechanism 32, the second tenon 323 and the second bayonet 324 are used to cooperate to achieve locking of the second snap arm 321 and the second snap groove 322 after engagement, so that the powder bin shell 1 and the waste powder bin shell 2 can be fully engaged; therefore, based on this structure, the connection structure does not need to be provided with too many clearance grooves and clearance holes, which effectively reduces the space occupied by the connection structure, thereby making the engagement process of the powder bin and the waste powder bin more convenient, more convenient for personnel to assemble, and effectively improving the production efficiency of the product.

[0026] A first abutting surface 3111 is formed on one side of the first clamping arm 311 close to the first clamping groove 312.

[0027] The first engaging groove 312 is provided with first guide walls 3121 disposed opposite to each other. When the first engaging arm 311 is engaged with the first engaging groove 312, the first abutting surface 3111 approaches and presses against the groove wall of the first engaging groove 312, and the first guide walls 3121 abut against opposite sides of the first engaging arm 311. At this point, the first engaging arm 311 is fully engaged with the first engaging groove 312, i.e., the first latch 314 is fully engaged with the first tenon 313. The abutment of the groove wall of the first engaging groove 312 against the first abutting surface 3111 restricts movement of the powder hopper housing 1 toward the waste powder hopper housing 2, preventing the first tenon 313 from dislodging from the first latch 314, thereby ensuring a secure engagement between the first engaging arm 311 and the first engaging groove 312.

[0028] The first guide walls 3121 are arranged at an angle on the opposing inner walls of the first engaging slot 312, and the width of the spacing between the opposing first guide walls 3121 gradually increases as the first engaging arm 311 approaches. When the first engaging arm 311 approaches the first engaging slot 312, the opposing sides of the first engaging arm 311 abut against the first guide walls 3121. As the spacing between the first guide walls 3121 narrows, the first tenon 313 and the first bayonet 314 gradually approach each other until they are aligned. The first guide walls 3121 provide guidance for pre-positioning the first snap mechanism 31.

[0029] The second engaging arm 321 is plate-shaped, and the second engaging slot 322 is provided with opposing second guide walls 3221. The opposing second guide walls 3221 are arranged at an angle, and the spacing between them is greater than the spacing between the first guide walls 3121. After the first engaging mechanism 31 is positioned and engaged, this structure allows for a wider range of positioning deviation calibration for the second engaging mechanism 32.

[0030] The second clamping arm 321 is configured in a square plate shape and a strip shape. Arc-shaped guide buffer portions 3211 are provided at the transition between opposite sides and the top of the second clamping arm 321. When the second clamping arm 321 approaches the second clamping slot 322, the guide buffer portions 3211 abut against the second guide wall 3221, guiding the second tenon 323 toward and retaining it in the second clamping notch 324. The guide buffer portions 3211 not only reduce stress concentration and protect the plate-shaped second clamping arm 321, but also facilitate the positioning and engagement of the second clamping arm 321 in the second clamping slot 322.

[0031] A latch bevel 33 is provided on the first latch 313 near the first latch opening 314, and a latch bevel 33 is also provided on the second latch 323 near the second latch opening 324. The provision of the latch bevel 33 facilitates the latch to be closer to the latch opening.

[0032] Preferably, the first and second connecting arms 311 and 321 are protruding from opposite sides of the powder hopper housing 1, and the first and second connecting slots 312 and 322 are formed on opposite sides of the waste powder hopper housing 2. The first latch 313 is protruding from the first connecting slot 312, and the first latch opening 314 is formed on the first connecting arm 311. The second latch 323 is protruding from the second connecting slot 322, and the second latch opening 324 is formed on the second connecting arm 321. Given that the volume of the powder hopper housing 1 is larger than that of the waste powder hopper housing 2, this structural arrangement further facilitates the connection and mating between the powder hopper housing 1 and the waste powder hopper housing 2.

[0033] Preferably, the powder bin housing 1, the first clamping arm 311 and the second clamping arm 321 are integrally formed, and the waste powder bin housing 2, the first clamping groove 312 and the second clamping groove 322 are integrally formed, which facilitates the production of the entire toner cartridge components.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
