Description

Technical Field

[0001] This utility model relates to the field of printer accessories technology, specifically to a large-capacity portable waste toner box. Background Technology

[0002] Laser printers and copiers are widely used in modern office equipment. These devices generate a certain amount of waste toner during printing and copying, which needs to be collected using waste toner cartridges. There are many types of waste toner cartridges on the market, which can be categorized by their internal capacity into different sizes: small, medium, and large. Large waste toner cartridges have a larger internal capacity, reducing the frequency of replacement or cleaning.

[0003] However, large-capacity waste toner boxes on the market typically use a snap-fit ​​assembly method, as they consist of an upper and lower cover. This method has several drawbacks. First, the snap-fit ​​is not secure enough and is prone to loosening. Second, while a very tight snap-fit ​​can prevent loosening, it makes subsequent cleaning difficult, requiring tools and making the process cumbersome. Finally, the snap-fit ​​mechanism is susceptible to breakage due to the clamping force, affecting its stability and usability, hindering easy installation and removal, and causing inconvenience to users. Therefore, we propose a large-capacity, portable waste toner box. Utility Model Content

[0041] Please see Figures 1-6 This utility model provides a technical solution: a large-capacity portable waste toner box, including an upper cover 1 and a lower cover 2 detachably installed on the bottom surface of the upper cover 1. The capacity between the upper cover 1 and the lower cover 2 can be between 1kg and 2kg depending on the printer model, which can meet the needs of large capacity. Guide protrusions 3 are fixedly installed on the inner walls of the four corners of the lower cover 2. The two guide protrusions 3 on one side are provided with rectangular grooves 30 that are connected to the outside at the top, and the two guide protrusions 3 on the other side are provided with annular grooves 5 that are connected to the outside at the top. Rectangular inserts 4 are fixedly installed at the two corners at one end of the upper cover 1, and the rectangular inserts 4 are inserted into the rectangular grooves 30. Cylindrical inserts 6 are fixedly installed at the two corners at the other end of the upper cover 1, and the cylindrical inserts 6 are inserted into the annular grooves 5. The rectangular groove 30 has a rectangular cross-section, while the cylindrical insert 6 and the annular groove 5 have circular cross-sections. The size of the rectangular insert 4 matches the size of the rectangular groove 30, and the size of the cylindrical insert 6 matches the size of the annular groove 5. The rectangular insert 4 and the guide protrusion 3, as well as the cylindrical insert 6 and the guide protrusion 3, are detachably connected by fastening screws 9, enabling the upper cover 1 and the lower cover 2 to achieve precise, foolproof insertion and positioning. The detachable connection by fastening screws 9 makes the connection between the upper and lower covers of the waste powder box more stable than the traditional snap-fit ​​method, preventing loosening. Disassembly is simple, requiring only the unscrewing of screws, and solves the problems of overly tight snap-fit ​​connections that are difficult to separate and snap-fit ​​parts that are easily broken.

[0042] Specifically, threaded holes 8 are provided on the bottom walls of both the rectangular groove 30 and the annular groove 5. The fastening screws 9 are threadedly connected to the threaded holes 8, realizing the function of fixing the upper and lower covers by tightening the screws. Compared with the snap-fit ​​structure, this method is more controllable in terms of installation and disassembly. Both the tightness of the installation and the ease of disassembly can be better controlled, which facilitates the daily maintenance of the waste powder box. A conical cavity 80 is provided at the top of the threaded hole 8. The top of the conical cavity 80 extends to the groove wall of the corresponding rectangular groove 30 and annular groove 5. The cavity wall of the conical cavity 80 is inclined downward at 30 to 60 degrees towards the threaded hole 8, which makes it easier for the fastening screws 9 to be inserted into the conical cavity 80 and then tightened into the threaded hole 8, achieving the effect of convenient installation.

[0043] In this embodiment, a plurality of heat sinks 23 are fixedly installed on the bottom plate of the lower cover 2. The top of the heat sink 23 is flush with the bottom wall of the lower cover 2, and the bottom of the heat sink 23 is flush with the bottom surface of the lower cover 2. Through the heat sink 23, the heat carried by the toner in the lower cover 2 can be dissipated in time, avoiding the situation where the temperature inside the upper cover 1 and the lower cover 2 is too high, causing the upper cover 1 and the lower cover 2 to expand and contract due to heat.

[0044] In this embodiment, both the rectangular insert 4 and the guide protrusion 3 are provided with vertical through holes 7 arranged in the vertical direction. The top of the vertical through hole 7 extends to the top surface of the upper cover 1. The fastening screw 9 is inserted from the vertical through hole 7, making the installation path of the fastening screw 9 more direct, reducing installation obstacles, and ensuring that the force is transmitted more evenly when the screw is tightened, thereby enhancing the reliability of the connection between the upper cover 1 and the lower cover 2.

[0045] In addition, a clamping ring 91 is fixedly installed on the smooth section of the top of the fastening screw 9, and a second sealing ring 92 is fitted on the fastening screw 9. The clamping ring 91 presses the second sealing ring 92 against the top surface of the upper cover 1. Through the second sealing ring 92, the opening of the vertical through hole 7 on the upper cover 1 can be sealed, so that even if the upper cover 1 and the lower cover 2 are rotated 180 degrees, the opening of the vertical through hole 7 will not leak toner, thus further ensuring the sealing effect.

[0046] Furthermore, a knob 90 is fixedly installed on the top of the fastening screw 9. The knob 90 rests against the top surface of the upper cover 1, allowing the operator to operate the fastening screw 9 by simply turning the knob 90 by hand without the need for tools such as screwdrivers. This greatly improves the efficiency of disassembly and assembly and reduces the difficulty of operation. Even non-professionals can easily disassemble and assemble the upper and lower covers of the waste powder box.

[0047] like Figure 2 As shown, side grooves 12 are provided at the four corners of the top cover 1, and the knob 90 is located in the side groove 12, providing ample operating space for the knob 90, avoiding interference between the hand and other parts of the top cover 1 during operation, making the rotation of the knob 90 smoother, and further optimizing the user's operating experience.

[0048] like Figure 4 As shown, a first sealing ring 20 is embedded in the top surface of the lower cover 2. After the upper cover 1 is closed, the bottom surface of the upper cover 1 abuts against the first sealing ring 20, forming an effective sealing structure. This can prevent waste powder in the waste powder box from leaking to the outside, protect the working environment from waste powder pollution, and also prevent waste powder leakage from harming the user's health.

[0049] like Figure 1 As shown, a groove 10 is provided on the top surface of the cover 1, and a handle 11 is hinged to the bottom wall of the groove 10. When it is necessary to move or transport the waste powder box, the user can easily pull up the handle 11, which is labor-saving and convenient. When not in use, the handle 11 can be stored in the groove 10 without taking up extra space, maintaining the overall simplicity and aesthetics of the waste powder box.

[0050] like Figure 2As shown, side frames 21 are fixedly installed on the sides of both the upper cover 1 and the lower cover 2. After the upper cover 1 and the lower cover 2 are closed, a central adhesive area 22 is formed between the two side frames 21. The central adhesive area 22 is used for adhesive tape. Adhesive tape can be used to stick and fix the tape around the central adhesive area 22. This not only further enhances the stability of the connection between the upper cover 1 and the lower cover 2, but also adds an extra layer of sealing protection. The dual measures effectively prevent waste powder leakage and improve the safety and reliability of the waste powder box.

[0051] When using the large-capacity portable waste powder box of this utility model, first place the lower cover 2 in a suitable position, pick up the upper cover 1, align the rectangular insert 4 at one end with the rectangular groove 30 in the guide protrusion 3 of the lower cover 2, and align the cylindrical insert 6 at the other end with the annular groove 5. Slowly lower the upper cover 1 so that the rectangular insert 4 and the rectangular groove 30, and the cylindrical insert 6 and the annular groove 5 are connected and engaged.

[0052] Next, rotate the knobs 90 in the four corner side grooves 12 of the upper cover 1 to drive the fastening screws 9 through the vertical through holes 7 in the rectangular insert 4 and guide protrusion 3 to connect with the threaded holes 8 on the bottom wall of the rectangular groove 30 and the annular groove 5. Tighten the knobs 90 to fix the upper cover 1 and the lower cover 2. If further reinforcement is needed, tape can be used to wrap around and stick the central adhesive area 22 formed by the side frames 21 of the upper and lower covers. Then install the assembled waste toner box into the corresponding position of the printer or copier.

[0053] When the waste powder box contains a large amount of waste powder and needs to be cleaned, first disconnect the equipment connection, remove the device, loosen the knob 90 and remove the fastening screw 9, separate the upper cover 1 and the lower cover 2, and then process the waste powder inside. After cleaning, reassemble according to the above steps, and it can be put into use again.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
