[0043] Example 1

[0044] like Figures 5 to 8 As shown, the toner supply box 100 includes a storage portion 110 for storing toner and an outlet 111 communicated with the storage portion 110. The toner supply box 100 also includes a locking member 120 and a reset member 130. The outlet 111 is a part of the storage portion 110.

[0045] The locking member 120 is movably disposed on the storage portion 110 and can be switched back and forth between a locking position 101 for locking the toner replenishing box 100 and an unlocking position 102 for unlocking the toner replenishing box 100 .

[0046] The reset member can generate a reset force to move the locking member 120 from the unlocking position 102 to the locking position 101; specifically, the reset member 130 is arranged between the locking member 120 and the storage part 110, and the reset force generated by the reset member 130 pushes the locking member 120 from the unlocking position 102 to the locking position 101.

[0047] The locking member 120 includes a locking portion that can engage and disengage with the locking step 16, and the locking portion can be a hook portion 121. When the locking member 120 is located at the locking position 101, the hook portion 121 of the locking member 120 is engaged with the locking step 16 of the mounting portion 10 on the electronic imaging device.

[0048] When the locking member 120 is located at the unlocking position 102 , the hook portion 121 is disengaged from the locking step 16 .

[0049] The locking member 120 is provided with an unlocking operation portion 122 , and the unlocking force received by the unlocking operation portion 122 overcomes the resetting force to push the locking member 120 from the locking position 101 to the unlocking position 102 .

[0050] Even if the controller, actuator or release lever of the electronic imaging device is damaged, the toner refill box 100 can still be disassembled by manually controlling the unlocking operation portion 122 to push the locking member from the locking position 101 to the unlocking position 102 .

[0051] When the locking member 120 is located at the locking position 101, the unlocking operation portion 122 is located above the mounting portion 10 along the height direction 01. The unlocking operation portion 122 is convenient for manual control, and the toner refill box 100 can be directly pulled out by directly pinching the opposite unlocking operation portion 122, which is convenient to operate.

[0052] Specifically, along the height direction 01, the hook portion 121 is fixed to the lower end of the arm portion 124 of the locking member 120, and the unlocking operation portion 122 is fixed to the upper side of the arm portion 124 of the locking member 120. Preferably, the unlocking operation portion 122 is not higher than the reset member 130.

[0053] The reset member 130 is a compression spring, one end of which is sleeved on a boss 123 extending radially along the storage portion 110 at the upper end of the locking member 120 near the center of the storage portion 110 , and the other end is inserted into a recess 113 on the storage portion 110 corresponding to the boss 123 .

A limiting ring 115 as a blocking portion is sleeved on the outer side of the storage portion 110, and the limiting ring 115 is sleeved on the outer side of the locking member 120. When the locking member 120 is located at the locking position 101, it abuts against the limiting ring 115. The locking member 120 is movably installed in the mounting groove 114 and can move along the radial direction of the storage portion 110. The height of the locking member 120 is limited by the upper wall 116 and the lower wall 117 of the mounting groove 114.

[0055] Preferably, the limiting ring 115 is installed outside the storage part 110 by bonding or interference fit. Along the height direction 01, a limiting boss 119 is provided on the lower side of the storage part 110. During the installation of the toner refill box 100, the limiting boss 119 prevents the limiting ring 115 from falling downward.

[0056] Example 2

[0057] like Figures 8 to 10 As shown, the difference between this embodiment and embodiment 1 lies in the locking member, the resetting member, the mounting groove and the mounting method thereof.

[0058] The toner supply box 200 includes a storage portion 210 for storing toner, a locking member 220 and a restoring member 230 .

[0059] The locking member 220 is hinged on the storage portion 210 via the shaft 218 and can be switched back and forth between the locking position 201 for locking the toner supply box 200 and the unlocking position 202 for unlocking the toner supply box 200. That is, the locking member 220 is movably disposed on the storage portion 210.

[0060] The reset member can generate a reset force to move the locking member 120 from the unlocking position 102 to the locking position 101; specifically, the reset member 230 is arranged between the locking member 220 and the storage part 210, and the reset force generated by the reset member 230 pushes the locking member 220 from the unlocking position 202 to the locking position 201.

[0061] The locking member 120 includes a locking portion that can engage and disengage with the locking step 16, and the locking portion can be a hook portion 121. When the locking member 220 is located at the locking position 201, the hook portion 221 of the locking member 220 is engaged with the locking step 16 of the mounting portion 10 on the electronic imaging device.

[0062] When the locking member 220 is located at the unlocking position 202 , the hook portion 221 is disengaged from the locking step 16 .

[0063] The locking member 220 is provided with an unlocking operation portion 222 , and the unlocking force received by the unlocking operation portion 222 overcomes the resetting force to push the locking member 220 from the locking position 201 to the unlocking position 202 .

[0064] Specifically, the shaft 218 is distributed along the tangential direction of the storage part 210. A torsion spring as a reset member 230 is installed on the shaft 218, and two arms of the torsion spring are respectively in contact with the storage part 210 and the locking member 220. The upper end of the arm 224 of the locking member 220 is hinged on the shaft 218. The limiting ring 215 as a blocking part is sleeved on the outside of the storage part 210, and the locking member 220 is in contact with the limiting ring 215 when it is located at the locking position 201.

[0065] This embodiment has all the technical advantages of the first embodiment. In addition, the locking member 220 can be installed via a hinge shaft to obtain better movement stability, thereby improving the smoothness of manual installation and removal of the toner refill box 200.

[0066] Example 3

[0067] like Figures 11 to 16 As shown, the toner supply box 300 includes a storage portion 310 for storing toner and an outlet 311 communicating with the storage portion 310. The toner supply box 300 also includes a locking member 320 and a reset member 330. The outlet 311 is a part of the storage portion 310.

[0068] The locking member 320 is movably disposed on the storage portion 310 and can be switched back and forth between a locking position 301 for locking the toner supply box 300 and an unlocking position 302 for unlocking the toner supply box 300 .

[0069] The reset member can generate a reset force to move the locking member 120 from the unlocking position 102 to the locking position 101; specifically, the reset member 330 is arranged between the locking member 320 and the storage part 310, and the reset force generated by the reset member 330 pushes the locking member 320 from the unlocking position 302 to the locking position 301.

[0070] The locking member 120 includes a locking portion that can engage with and disengage from the locking step 16, and the locking portion may be a hook portion 121. The locking member 320 has a hook portion 321 extending radially along the storage portion 310, and a guide surface 325 is further provided on the locking member 320.

[0071] When the locking member 320 is located at the locking position 301 , the hook portion 321 is engaged with the locking step 16 of the mounting portion 10 on the electronic imaging device, and the guide surface 325 is inserted into the groove 14 below the locking step 16 .

[0072] When the storage portion 310 rotates around its axis extending in the height direction 01, the locking member 320 is driven to move circumferentially, and the guide surface 325 abuts against the side wall 15 of the groove 14. The side wall 15 of the groove 14 forces the locking member 320 to move radially along the storage portion 310 to the unlocking position 302 through the guide surface 325.

[0073] By rotating the toner supply box 300, the locking member 320 can be forced to move to the unlocking position 302 by itself, which has a simple structure, convenient operation and low manufacturing cost. It can be seen that the storage part 310 can be equivalent to the unlocking operation part.

[0074] Specifically, along the height direction 01 , the hook portion 321 is fixed to the lower end of the arm portion 324 of the locking member 320 , and the guide surfaces 325 are provided on both sides of the hook portion 321 along the circumferential direction.

[0075] The resetting member 330 is a compression spring, one end of which is sleeved on a boss 323 extending radially along the storage portion 310 on the side of the locking member 320 near the center of the storage portion 310 , and the other end is inserted into a recess 313 on the storage portion 310 corresponding to the boss 323 .

[0076] Preferably, the storage portion 310 is provided with a mounting groove 314 for accommodating the locking member 320. A limiting ring 315 as a blocking portion is sleeved on the outer side of the storage portion 310, and the limiting ring 315 is sleeved on the outer side of the locking member 320. When the locking member 320 is located at the locking position 301, it abuts against the limiting ring 315. The locking member 320 is movably installed in the mounting groove 314 and can move along the radial direction of the storage portion 310. The height of the locking member 320 is limited by the upper wall 316 and the lower wall 317 of the mounting groove 314.

[0077] Preferably, the restriction ring 115 is installed on the outside of the storage portion 110 by bonding or interference fit.

[0078] In the height direction 01, the locking members 320 are arranged in pairs opposite to each other at the lower side of the storage portion 310. The locking members 320 are not limited to one pair, but may be two pairs or more.

[0079] Example 4

[0080] The main difference between this embodiment and the third embodiment lies in the connection relationship between the locking member, the resetting member and the storage part.

[0081] like Figures 17 to 22 As shown, the toner supply box 400 includes a storage portion 410 for storing toner and an outlet 411 communicating with the storage portion 410. The toner supply box 400 also includes a locking member 420 and a reset member 430. The outlet 411 is a part of the storage portion 410.

[0082] The locking member 420 is movably disposed on the storage portion 410 and can be switched back and forth between a locking position 401 for locking the toner replenishing box 400 and an unlocking position 402 for unlocking the toner replenishing box 400 .

[0083] The reset member can generate a reset force to move the locking member 120 from the unlocking position 102 to the locking position 101; specifically, the reset member 430 is arranged between the locking member 420 and the storage part 410, and the reset force generated by the reset member 430 pushes the locking member 420 from the unlocking position 402 to the locking position 401.

[0084] The locking member 120 includes a locking portion that can engage with and disengage from the locking step 16, and the locking portion may be a hook portion 121. The locking member 420 has a hook portion 421 extending radially along the storage portion 410, and a guide surface 425 is further provided on the locking member 420.

[0085] When the locking member 420 is located at the locking position 401 , the hook portion 421 is engaged with the locking step 16 of the mounting portion 10 on the electronic imaging device, and the guide surface 425 is inserted into the groove 14 below the locking step 16 .

[0086] When the storage portion 410 rotates around its axis extending in the height direction 01, the locking member 420 is driven to move circumferentially, and the guide surface 425 abuts against the side wall 15 of the groove 14. The side wall 15 of the groove 14 forces the locking member 420 to move radially along the storage portion 410 to the unlocking position 402 through the guide surface 425.

[0087] By rotating the toner supply box 400 to Fig.21The position shown in the figure can force the locking member 420 to move to the unlocking position 402 by itself, which has a simple structure, convenient operation and low manufacturing cost. It can be seen that the storage portion 410 can be equivalent to the unlocking operation portion.

[0088] Specifically, the locking member 420 is integrally formed with the arm 424. Along the height direction 01, the hook 421 is formed at the lower end of the arm 424, and the guide surface 425 is arranged on one side of the hook 421 along the circumferential direction. The elastic arm 424 serves as a reset member 430.

[0089] Preferably, the storage part 410 is cylindrical. The locking member 420 is integrally formed with the storage part 410. Two pairs of opposite locking members 420 are provided at the lower side of the storage part 410 along the height direction 01.

[0090] See also Fig. 22 As an improvement, the hook portion 421 is provided with guide surfaces 425 on both sides of the storage portion 410 in the circumferential direction. The storage portion 410 can be rotated in both directions to lock or unlock the toner supply box 400, which is more convenient to use.

[0091] The number of the locking members 420 is not limited to one pair, but may be two pairs or more.

[0092] The guide surface 425 is not limited to being used in the embodiment 4, but can also be used in the embodiments 1 and 2, so that the embodiments 1 and 2 can also be switched from the locked state to the unlocked state by rotating the storage unit.

[0093] The toner refill box in all the above embodiments can be unlocked not only manually but also by using Fig.23 The release lever 20 of the electronic imaging device shown is unlocked. When the toner refill box is installed on the mounting portion 10 and is in a locked state, the release lever 20 only needs to be inserted into the avoidance groove 17 of the mounting portion 10 to push the locking member from the locked position to the unlocked position.

[0094] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
