AI Technical Summary
Existing printer toner cartridges do not promptly alert the printer when excessive waste toner accumulates in the waste toner compartment. This causes waste toner to squeeze the sealing cap and fall onto the transfer roller surface, resulting in spots and blurry lines on the paper surface and affecting print quality.
A waste powder recycling mechanism including a waste powder bin and a buffer bin was designed. Through a combination of a connecting port, a push rod and a touch switch, the user is reminded that the waste powder bin has reached its limit. The waste powder can be conveniently discharged by rotating the knob and connecting rod, avoiding direct contact between the waste powder and the discharge port.
It effectively reminds users that the waste toner storage capacity has reached its limit, preventing waste toner from falling onto the transfer roller surface, improving print quality, simplifying the waste toner cleaning process, and avoiding direct contact with the waste toner discharge port.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer toner cartridge technology, and in particular to a printer toner cartridge with good sealing performance. Background Technology
[0002] Printer toner cartridges are key components in laser printers or copiers. During printing, the laser scanning unit in the printer emits a laser beam based on the printing content, which then illuminates the surface of the toner cartridge. When laser light irradiates a region, the resistance of the photosensitive layer changes, the positive charge disappears, and an electrostatic latent image is formed. The negatively charged toner on the developing roller is attracted to the area with the electrostatic latent image on the drum surface, converting the latent image into a visible toner image. As the paper passes between the drum and the transfer roller, the transfer roller charges the paper with a positive charge, attracting the toner on the drum surface to the paper. To allow the drum to perform the next printing cycle, the drum cleaning blade scrapes off the residual toner on the transfer roller surface and then transports the waste toner to the waste toner hopper through the waste toner transport channel. However, in existing devices, users cannot know the amount of waste toner in the waste toner hopper without opening the printer casing and penetrating the drum. This leads to excessive waste toner accumulation in the waste toner hopper, which can force open the seal of the waste toner hopper, causing waste toner to fall onto the transfer roller surface, resulting in spots and blurred lines on the paper surface, thus degrading print quality.
[0003] The purpose of this invention is to provide a printer toner cartridge with good sealing performance to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the prior art as described in the background section by providing a printer toner cartridge with good sealing performance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A printer toner cartridge with good sealing performance includes a toner cartridge body and a waste toner recycling mechanism. The waste toner recycling mechanism is located on one side of the toner cartridge body. The waste toner recycling mechanism includes a waste toner compartment and a buffer compartment. The waste toner compartment is located near the toner cartridge body and is connected to it. A buffer compartment is located on the other side of the waste toner compartment.

A connecting tube is connected to the other end of the connecting port, and a push rod is fitted into the inside of the connecting tube. A tactile switch is fitted into the end of the connecting tube away from the push rod. A sound generator is located on the left side of the connecting tube, on the inner wall of the buffer compartment. A knob is located on the outer side of the connecting tube, on the outer wall of the waste toner recycling mechanism, and the connecting tube passes through the outer wall of the waste toner recycling mechanism and is fixedly connected to the knob.
[0007] Preferably, the end of the connecting pipe near the communication port is fixedly connected to a sealing sleeve on the outer wall of the communication port, and the sealing sleeve wraps around the outside of the communication port.
[0008] Preferably, the inner wall of the buffer chamber is provided with a threaded hole, and the connecting port is composed of a bolt and a connecting pipe, with the bolt portion of the connecting port being fitted into the threaded hole on the inner wall of the buffer chamber.
[0009] Preferably, the upper and lower ends of the outer side of the connecting pipe are fixedly connected to connecting rods, and the other end of the connecting rods is fixedly connected to the bolt portion of the connecting port.
[0010] Preferably, the waste powder recycling mechanism has a powder discharge port on its outer side, and the powder discharge port is connected to the outer wall of the waste powder recycling mechanism and the internal space of the buffer chamber.

[0012] Preferably, the speaker has a battery compartment inside, which powers the speaker, and the tactile switch is connected to the battery compartment inside the speaker via a wire.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. In this utility model, by setting a connecting port and a push rod, when the waste toner storage inside the waste toner compartment reaches its limit, the waste toner will squeeze and push the push rod, causing the push rod to trigger a touch switch. After the touch switch is triggered, the sounder will emit a sound to remind the user that the waste toner storage inside the toner cartridge has reached its limit, thereby avoiding the situation where waste toner falls on the surface of the transfer roller, causing the paper surface to have spots and blurry lines, resulting in a decrease in print quality.
[0015] 2. By setting up connecting rods and connecting pipes, when users need to clean the waste powder accumulated inside the waste powder bin, they can rotate the knob to make the connecting pipe rotate through the connecting rod to drive the connecting port to rotate, so that the waste powder can be discharged from the waste powder bin into the buffer bin. Then the waste powder inside the buffer bin is discharged to the outside through the powder discharge port. This allows users to easily and quickly discharge the powder while avoiding direct contact with the waste powder discharge port. Attached Figure Description

[0025] Example
[0026] Reference Figure 1-4A printer toner cartridge with good sealing performance includes a toner cartridge body 1 and a waste toner recycling mechanism 2. The waste toner recycling mechanism 2 is located on one side of the toner cartridge body 1. The waste toner recycling mechanism 2 includes a waste toner compartment 5 and a buffer compartment 6. The waste toner compartment 5 is located near the toner cartridge body 1 and is connected to the toner cartridge body 1. The buffer compartment 6 is located on the other side of the waste toner compartment 5. A connecting port 7 is fitted into the inner wall of the buffer compartment 6 near the waste toner compartment 5. A connecting pipe 9 is connected to the other end of the connecting port 7. A push rod 8 is fitted into the inside of the connecting pipe 9. A tactile switch 10 is fitted into the end of the connecting pipe 9 away from the push rod 8. A sound generator 11 is located on the left side of the connecting pipe 9, on the inner wall of the buffer compartment 6. A knob is located on the outer side of the connecting pipe 9, on the outer wall of the waste toner recycling mechanism 2. 3. The connecting pipe 9 passes through the outer wall of the waste powder recycling mechanism 2 and is fixedly connected to the knob 3. With this design, when the waste powder in the waste powder bin 5 is too much, the waste powder will flow into the interior of the connecting port 7. When the waste powder in the waste powder bin 5 reaches its limit, the waste powder will squeeze and push the push rod 8, causing the push rod 8 to move along the interior space of the connecting pipe 9 toward the tactile switch 10 until the push rod 8 contacts the tactile switch 10, causing the contacts inside the tactile switch 10 to close. Since the inside of the sound generator 11 is equipped with a battery compartment, the battery compartment supplies power to the sound generator 11. The tactile switch 10 is connected to the battery compartment inside the sound generator 11 through a wire. When the tactile switch 10 is triggered, the sound generator 11 is powered on. After the sound generator 11 is powered on, it will emit a sound to remind the user that the waste powder in the waste powder bin 5 inside the toner cartridge has reached its limit.
[0027] It should be noted that the push rod 8 is made entirely of rubber, with both ends of the push rod 8 being hard rubber and the middle part being soft rubber. This design allows the push rod 8 to still have a certain degree of retraction after touching the light switch 10, so that after the sound generator 11 is triggered, the push rod 8 can increase the amount of waste powder accumulated by its own retraction.
[0028] The end of the connecting pipe 9 near the connecting port 7 is fixedly connected to a sealing sleeve 13 on the outer wall of the connecting port 7, and the sealing sleeve 13 wraps around the outside of the connecting port 7. This design prevents waste powder from falling into the buffer chamber 6 from the connection between the connecting port 7 and the connecting pipe 9.
[0029] The inner wall of the buffer chamber 6 is provided with threaded holes. The connecting port 7 is composed of bolts and a connecting pipe. The bolt portion of the connecting port 7 is fitted into the threaded holes on the inner wall of the buffer chamber 6. Connecting rods 12 are fixedly connected to both the upper and lower ends of the connecting pipe 9, and the other end of the connecting rod 12 is fixedly connected to the bolt portion of the connecting port 7. With this design, when the user needs to clean the waste powder accumulated inside the waste powder chamber 5, the user can rotate the knob 3 to rotate the connecting pipe 9 through the connecting rods 12, causing the connecting port 7 to rotate until the connecting port 7 disengages from the inner wall of the buffer chamber 6. Afterwards, the user can stand the toner cartridge upright with the buffer chamber 6 facing downwards, so that the waste toner stored inside the waste toner chamber 5 falls into the buffer chamber 6 through the threaded hole between the buffer chamber 6 and the waste toner chamber 5. Since the waste toner recycling mechanism 2 has a discharge port 4 on its outer side, and the discharge port 4 passes through the outer wall of the waste toner recycling mechanism 2 and is connected to the internal space of the buffer chamber 6, the discharge port 4 is rectangular in shape, and a snap-on sealing cover is fitted on the outer side of the discharge port 4. At this time, the user can open the sealing cover on the outer side of the discharge port 4 so that the waste toner inside the buffer chamber 6 can be discharged to the outside through the discharge port 4.
[0030] Working principle: When the waste powder in the waste powder bin 5 is excessive, the waste powder will flow into the connecting port 7. When the waste powder in the waste powder bin 5 reaches its limit, the waste powder will squeeze and push the push rod 8, causing the push rod 8 to move along the internal space of the connecting pipe 9 towards the tactile switch 10 until the push rod 8 contacts the tactile switch 10, causing the contacts inside the tactile switch 10 to close. Since the generator 11 has a battery compartment inside, the battery compartment supplies power to the generator 11. The tactile switch 10 is connected to the battery compartment inside the generator 11 through a wire. When the tactile switch 10 is triggered, the generator 11 is powered on, and the generator 11 will emit sound. The sound alerts the user that the waste toner cartridge 5 inside the toner cartridge has reached its limit. When the user needs to clean the waste toner inside the waste toner cartridge 5, the user can rotate the knob 3 to make the connecting tube 9 rotate through the connecting rod 12 to drive the connecting port 7 to rotate until the connecting port 7 is disengaged from the inner wall of the buffer chamber 6. Then the user can stand the toner cartridge with the buffer chamber 6 facing down, so that the waste toner inside the waste toner cartridge 5 falls into the buffer chamber 6 through the threaded hole between the buffer chamber 6 and the waste toner cartridge 5. Then the user can open the sealing cover on the outside of the toner discharge port 4 so that the waste toner inside the buffer chamber 6 can be discharged to the outside through the toner discharge port 4.
[0031] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
[0032] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
