The second elastic member 60 is a compression spring, and the second elastic member 60 is disposed in the tube portion 21 of the fixing base 20, between the bottom wall 27 and the head portion 51 of the pushing member 50 and extends into the small diameter section 26, so that the second elastic member 60 applies a force to the pushing member 50 toward the advancing position P3.
The seal 70 is annular and is disposed on a side of the disk 31 of the valve member 30 adjacent to the opening 22.
Referring to fig. 6, when the toner cartridge 1 is not assembled in the electronic imaging device, the disc 31 of the valve member 30 is subjected to the force of the first elastic member 40 towards the opening 22, at this time, the pushing member 50 is located at the advanced position P3, the head 51 of the pushing member 50 extends into the retainer 35 of the valve member 30 and abuts against the disc 31 of the valve member 30, the engaging portion 55 of the pushing member 50 is located in the tube 21, the pushing member 50 is subjected to the force of the second elastic member 60 to apply a force to the valve member 30 towards the opening 22, that is, the valve member 30 is simultaneously pushed by the first elastic member 40 and the pushing member 50, so that the sealing member 70 abuts against the opening 22 and deforms in a compression manner, the opening 22 can be reliably closed without powder leakage, and the valve member 30 cannot be separated from the opening 22 due to the diameter D1 of the disc 31 of the valve member 30 being larger than the diameter D2 of the opening 22.
When the toner cartridge 1 is mounted to the electronic imaging device, the abutting member 7 extends into the opening 22 and pushes against the valve member 30, and simultaneously overcomes the elastic force of the first and second elastic members 40 and 60 to move the valve member 30 and the pushing member 50 inward together, that is, to move the pushing member 50 toward the retreating position P4, the two clamping portions 55 of the pushing member 50 respectively have a slope 56 (as shown in fig. 5), the slope 56 of the clamping portion 55 abuts against the hole edge of the opening 29 during the process of passing the clamping portion 55 through the opening 29, so that the rod portion 53 is pressed and deformed to pass through the opening 29, and when the clamping portion 55 passes through the opening 29, the rod portion 53 returns to its original shape as shown in fig. 7, the clamping portion 55 is limited by the opening 29 to maintain the pushing member 50 at the retreating position P4, at this time, the clamping portion 55 is located outside the tube portion 21, the valve member 30 is maintained at the opening position P2, and the two-way groove 23 is communicated with the opening 22, so that the toner can enter the toner inlet 8 from the inside of the housing 3 through the two-way opening 23. When the pushing member 50 is located at the retracted position P4, as shown in fig. 7, the locking portion 55 is located outside the pipe portion 21, so that the pushing member 50 cannot be moved from the retracted position P4 to the advanced position P3 by the force of the second elastic member 60.
When the toner cartridge 1 is removed, the valve member 30 is returned from the open position P2 to the closed position P1 by the force of the first elastic member 40, so that the valve member 30 closes the opening 22 again, and the ejector 50 is maintained at the retracted position P4, as shown in fig. 8.
Through the above structural design, the first and second elastic members 40 and 60 of the leakage-blocking device 10 apply force to the opening 22 from the valve member 30, so that the toner cartridge 1 can be sealed before being assembled into the electronic imaging device, and toner leakage is avoided; when the toner cartridge 1 is mounted, the pushing member 50 is maintained at the retracted position P4, so that when the toner cartridge 1 is removed and assembled again, the user only needs to overcome the force of the first elastic member 40, and consumes less force to complete the mounting, thereby achieving the purpose of the present invention.
Other variations of the toner cartridge structure are possible based on the design spirit of the present invention, such as: the limiting portion 28 of the fixing base 20 can be engaged with the engaging portion 55 of the pushing member 50 by magnetic attraction or other engaging means, so long as the pushing member 50 can be maintained at the retracted position P4; or the head 51 of the pushing member 50 may be omitted, so long as the pushing member 50 can push against the valve member 20 when in the advancing position P3; alternatively, the seal 70 may be not annular in shape, but may be disk-shaped, etc., and any such structural variations that may be easily contemplated are intended to be encompassed by the present invention.
