Description

Technical Field

[0001] This utility model relates to a powder box that is easy to add powder to. Background Technology

[0002] Currently, most printer toner cartridges on the market are single-use. Once the toner in the cartridge is used up, it is discarded, which wastes resources. Alternatively, the toner cartridge is disassembled, new toner is added to the storage compartment, and then the cartridge is reinstalled. This disassembly and reassembly process can easily damage the internal structure, and during the toner refilling process, toner particles can easily fly around and be inhaled by the user, causing health problems. Summary of the Invention

[0003] The purpose of this utility model is to provide an easy-to-fill powder box, including a powder box with a powder filling compartment and a powder storage compartment inside. A partition is provided between the powder filling compartment and the powder storage compartment. The partition has a plurality of powder drop holes arranged in an array. A baffle is movably provided under the partition to close the plurality of powder drop holes. The partition has an elastic lifting part connected to the baffle. The powder filling compartment has a powder filling port, which corresponds vertically to the elastic lifting part. The powder filling port has a screw cap, and the screw cap has a pin extending towards the partition. The lower end of the pin abuts against the elastic lifting part.

[0004] Preferably, the elastic lifting part includes an installation slot on the partition plate, an abutment and a spring are provided in the installation slot, the side of the abutment slides with the installation slot, the lower part of the abutment is fixedly connected to the stop bar, and the upper and lower ends of the spring are respectively connected to the abutment and the inner wall of the installation slot.

[0005] Preferably, the upper part of the abutment seat is provided with a material blocking head, the material blocking head is located above the partition, and the cross-section of the material blocking head is a trapezoid that is narrower at the top and wider at the bottom.

[0006] Preferably, the baffles are arranged in a crisscross pattern, and the ends of the baffles are provided with guide blocks. The inner sidewall of the powder storage bin is provided with opposing vertical guide grooves, and the guide blocks are slidably disposed in the corresponding vertical guide grooves.

[0007] Preferably, the spun cap includes a plug and a cover plate. The plug is disposed below the cover plate. The plug has an external thread on its outer side and a corresponding internal thread on the inner side of the powder filling port. The plug of the spun cap is threaded into the powder filling port.

[0008] The advantages and beneficial effects of this utility model are as follows: It provides an easy-to-refill toner cartridge, which is provided with a toner filling compartment and a toner storage compartment inside the cartridge body. New toner is added to the toner filling compartment through the toner filling port. The toner filling port is closed by screwing on the cap. Pressing down on the cap opens the toner drop hole, connecting the toner filling compartment and the toner storage compartment. New toner enters the toner storage compartment for use without disassembling the toner cartridge, ensuring the sealing performance of the toner cartridge, reducing toner particle flying, and facilitating the replenishment of the printer toner cartridge.

[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0012] The specific technical solution of this utility model is as follows:

[0013] like Figure 1 and Figure 2 As shown, an easy-to-fill powder box includes a powder box 1. The powder box 1 has a powder filling compartment 2 and a powder storage compartment 3 arranged vertically inside. A partition 4 is provided between the powder filling compartment 2 and the powder storage compartment 3. The partition 4 has a plurality of powder dropping holes 5 arranged in an array. A baffle 6 for closing the plurality of powder dropping holes 5 is movably provided under the partition 4. The partition 4 has an elastic lifting part 7 connected to the baffle 6. The powder filling compartment 2 has a powder filling port 8. The powder filling port 8 is vertically aligned with the elastic lifting part 7. The powder filling port 8 is provided with a screw cap 9. The screw cap 9 has a pin 10 extending towards the partition 4. The lower end of the pin 10 abuts against the elastic lifting part 7.

[0014] The aforementioned elastic lifting part 7 includes an installation slot 71 on the partition 4. The installation slot 71 contains an abutment seat 72 and a spring 73. The side of the abutment seat 72 is slidably engaged with the installation slot 71. The lower part of the abutment seat 72 is fixedly connected to the baffle 6. The upper and lower ends of the spring 73 are respectively connected to the abutment seat 72 and the inner wall of the installation slot 71. Specifically, the elastic lifting part 7 makes the baffle 6 fit tightly against the bottom surface of the partition 4, thereby blocking several powder dropping holes 5 and preventing communication between the powder adding chamber 2 and the powder storage chamber 3.

[0015] The upper part of the aforementioned abutment seat 7 is provided with a material blocking head 74, which is located above the partition plate 4. The cross-section of the material blocking head 74 is a trapezoid with a narrow top and a wide bottom. Specifically, the material blocking head 74 prevents carbon powder from entering the installation channel 71.

[0016] The aforementioned baffles 6 are arranged in a crisscross pattern. The ends of the baffles 6 are provided with guide blocks 62. The inner sidewall of the powder storage chamber 3 is provided with opposing vertical guide grooves 61. The guide blocks 62 are slidably disposed in the corresponding vertical guide grooves 61. Specifically, this makes the up-and-down movement of the baffles 6 in the powder storage chamber 3 more stable.

[0017] The aforementioned spun cap 9 includes a plug 91 and a cover plate 92. The plug 91 is located below the cover plate 92. The plug 91 has an external thread on its outer side, and the powder filling port 8 has a corresponding internal thread on its inner side. The plug 91 of the spun cap 9 is threaded into the powder filling port 8. Specifically, the spun cap 9 is screwed into the powder filling port 8 through the plug 91, and the cover plate 92 covers the powder filling port 8.

[0018] When new toner needs to be added, first rotate the screw cap 9 to open the toner filling port 8. The baffle 6, through the spring 73 of the elastic lifting part 7, presses the baffle 6 tightly against the bottom surface of the partition 4, thereby blocking several toner drop holes 5 and preventing the toner filling chamber 2 from communicating with the toner storage chamber 3. Then, add new toner into the toner filling chamber 2 through the toner filling port 8. Next, rotate the screw cap 9 onto the toner filling port 8 to close the toner filling port 8. During the downward pressing of the screw cap 9, the ejector pin 10 presses down and moves the abutment seat 71 of the elastic lifting part 7. The abutment seat 71 moves the baffle 6 downward, opening several toner drop holes 5 on the partition 4, connecting the toner filling chamber 2 and the toner storage chamber 3. New toner enters the toner storage chamber 3 through several toner drop holes 5 for use. Compared with the existing technology, it is not necessary to disassemble the toner cartridge 1, which ensures the sealing performance of the toner storage chamber 3 of the toner cartridge 1, reduces the flying of toner particles, and facilitates the replenishment of ink for the printer toner cartridge.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
