Figure 6 is a perspective view of a toner bottle having a powder adding device of the present invention.

Referring to Fig. 1, the powder adding device 1 includes a casing 11, a spiral powder feeding roller 12, a seal ring 13, a motor base, a motor 15, a seal ring 17, and a stirring frame 18. The outer surface of the housing 11 is provided with a battery compartment 111 and a motor switch button 112. The battery compartment 111 is for housing a battery, and the open end of the battery compartment 111 is covered by a detachable cover 1111. The detachable cover 1111 is used to replace the battery, so that the powder adding device 1 is continuously used. The front end of the tapered tube 115 of the housing 11 is a powder filling port 116, and the rear end of the housing 11 is provided with a connecting portion 114 for sealingly abutting the connection end of the toner bottle mouth. The connecting portion 114 is provided with an internal thread, and the connecting end of the bottle opening of the toner bottle is provided with an external thread, and the thread of the connecting portion 114 is closely matched with the external thread of the connecting end to prevent the powder from floating outward when the powder is added. The connecting portion of the housing portion 11 of the housing 11 and the connection end of the toner bottle can also be designed as a snap-fit connection, and if necessary, a sealing member can be added to prevent toner from leaking when the powder is added.

The motor base is a combination of a mounting cavity 14 and a cover 16. Referring to Figures 2 and 3, Figures 2 and 3 show the internal structure of the housing 11 for reflecting the relative positional relationship of the housing 11 and the mounting cavity 14. The mounting cavity 14 is open at one end and closed at the other end and is provided with a communication hole 142 at the center. The mounting cavity 14 projects three support plates 141 radially outward on the outer circumference near the closed end, and each of the two support plates 141 is at an angle of 120 degrees in the circumferential direction. Six fixing protrusions 113 are formed on the inner surface of the casing 11, and the two fixing protrusions 113 are formed in a group of three. Each support plate 141 is snap-fitted in each set of fixing protrusions 113. In order to prevent the support plate 141 from falling off during the working process, the support plate 141 can be clamped into each set of the fixing protrusions 113 in a tightly fitting manner during the installation. During the operation of the motor 15, the motor base is vibrated and a force opposite to the direction of rotation of the motor 15 is generated, and the fixing protrusion 113 prevents the motor base from rotating out of the mounting position.

In addition to the above-described fixing means, there are other ways to fix the motor base to the housing 11. The support plate 141 may be directly welded to the casing 11 by welding, or a plurality of buckles may be designed on the inner side of the casing 11, and the support plate 141 may be fixed to the inner side of the casing 11 by means of a snap.

The number of support plates 141 is also not limited to three. Referring to Fig. 4, the number of the support plates 141' is two, as long as the support plates 141' are symmetrically disposed, and the contact area with the inner side of the casing 11' is sufficiently large to satisfy the support of the motor 15 and the normal operation of the powder adding device 1. For the purpose, the fixing plate 141' can be fixed by welding or snapping, or the supporting plate 141' can be tightly fitted in each set of fixing protrusions 113' by gluing. For the same reason, the number of the support plates 141' may be three or more, as long as the support plates 141' are symmetrically disposed, and the contact area with the inside of the casing 11' is sufficiently large to satisfy the supporting motor 15 and the powder adding device. 1 The purpose of normal operation is sufficient, but the number of support plates 141' is not excessive, and too much is easy to block the transportation of the toner.

When the snap fit is used, if the width of the support plate 141 in the circumferential direction is relatively narrow, the buckle on the inner side of the housing 11 can directly engage the left and right side edges of the support plate 141. If the width of the support plate 141 in the circumferential direction is relatively large, the buckle on the inner side of the housing 11 may directly fit the left and right side edges of the support plate 141, and one or one may be designed at the mounting edge of the support plate 141. In the above opening/cutting, the opening/cutting is engaged with the snap-fit of the housing 11 for the purpose of fixing. When the width of the support plate 141 in the circumferential direction is relatively large, one or more openings may be formed in the center of the support plate 141 without affecting the strength of the support plate, so that the toner smoothly passes through the opening of the support plate 141. It is blocked by the support plate 141 as little as possible.

Referring to FIG. 5, the mounting end of the spiral powder feeding roller 12 is a groove, and the motor 15 adopts a double-out shaft motor. One end shaft of the motor 15 passes through the connecting hole 142 of the mounting cavity 14 (see FIG. 3) and the spiral powder feeding roller 12 The groove is tightly fitted to achieve mounting of the spiral powder feed roller 12 on one end shaft of the motor 15. The cover 16 is used to cover the open end of the mounting cavity 14. The one end of the cover 16 can be fixed on the outer circumference of the mounting cavity 14 near the open end by bonding/welding, and the other end of the cover 16 has a communication hole 161 for stirring. The connecting end of the frame 18 is a recess, and the other end shaft of the motor 15 is tightly engaged with the groove of the agitating frame 18 through the communicating hole 161 of the cover 16, so that the agitating frame 18 is mounted on the other end shaft of the motor.

The assembling process of the powder adding device 1 is as follows. First, the motor 15 is loaded into the mounting cavity 14, and the cover 16 is bonded/welded to the outer circumference of the mounting cavity 14, and one end of the motor 15 is connected to the connecting hole of the mounting cavity 14 through the mounting hole 14. 142 is tightly engaged with the groove of the spiral powder feeding roller 12, and the other end connecting shaft of the motor 15 is tightly engaged with the groove of the stirring frame 18 through the communication hole 161 of the cover 16, and the three supporting plates 141 are passed through the above bonding/ The welding/snapping method achieves the fixing of the motor base in the housing 11, thereby completing the assembly process of the powder adding device 1.

The spiral powder feeding roller 12 is located in the tapered tube 115 for feeding the toner to the powder filling port of the powder box to accelerate the speed of the powder. The pitch of the spiral powder feed roller 12 is designed according to the magnitude of the corresponding powder feed amount. The free end of the spiral powder feeding roller 12 is within 5 mm from the powder adding port 116 or within 5 mm of the protruding powder opening 116 to ensure stable powder feeding.

Referring to Fig. 6, when filling the powder, the user needs to unscrew the lid of the toner bottle, tear off the sealing film, and then screw the powder adding device 1 to the opening of the toner bottle body 2, and then add the powder opening 116. Align the powder filling port of the powder container to be powdered, press the motor switch button 112, start the motor 15, and rotate the spiral powder feeding roller 12 and the stirring frame 18 simultaneously to achieve powdering. When the addition of the powder is completed, the motor 15 is turned off, the spiral powder feed roller 12 and the agitator 18 stop the powder feeding, and the powder addition is completed.

When the powder adding device 1 is mounted on the bottle body 2, the stirring frame 18 extends into the bottle mouth of the bottle body 2, and during the operation of the powder adding device 1, the toner in the bottle body 2 is agitated to prevent accumulation and accelerate the toner. The speed is moved to the mouth of the bottle 2.

In order to prevent the motor 15 from being damaged when the toner enters the motor seat during the powder application, the seal rings 13 and 17 are provided in the connection hole 142 and the connection hole 161.

The motor 15 functions to drive the rotation of the spiral powder feed roller 12 and the agitator 18, and the motor 15 is a low speed motor.

There are already motors with better sealing performance on the market. The motor itself has a mounting portion that can be directly installed in the cavity of the housing 11. Such a motor is more expensive. When using a motor with low price and poor sealing performance, in order to prevent the motor from being damaged when the toner enters the motor, it is necessary to install the motor seat on the motor, and then install the motor seat in the housing 11, thus protecting The function of the motor also enables the motor to be mounted in the cavity of the housing 11.

It is to be understood that the above examples are only illustrative of the invention and are not to be construed as limiting the scope of the invention. Any equivalent technical transformation based on the inventive spirit of the present invention is within the scope of the present invention as a person of ordinary skill in the art.

The powder adding device of the present invention is designed for replenishing toner powder to a process cartridge with a toner bottle, and the toner bottle matched with the powder adding device is extremely smooth in the process of replenishing the toner, and can effectively prevent the toner from being externally Environmental leakage.
