Embodiment 1

[0048] Such as image 3 As shown, this embodiment provides a developer cartridge 3 that can be detachably installed on an image forming device. The developer cartridge 3 includes a box body 30, a detection gear 4, a protective cover 5, a positioning member 6, an elastic element 7, a transfer gear 8 and a developing element 16 (see Figure 4); the detection gear 4 includes a detection protrusion 41 for detection, a gear portion (toothed segment) 43, a missing tooth portion (toothless segment) 44 and a support protrusion 42, and the detection protrusion 41 is made of an elastic material; the protective cover 5 The opening 51 is included, and the opening 51 is used for the leakage detection protrusion 41 to facilitate the detection of the detection protrusion 41; the detection gear 4, the positioning member 6 and the elastic element 7 form a detection mechanism.

[0049] Such as Figure 4 As shown, the box body 30 of the developing cartridge includes a side wall 31, a position-...

Embodiment 2

[0061] Unless otherwise specified, the developing cartridge used in this embodiment is the same as that in Embodiment 1.

[0062] In this embodiment, the developing cartridge may not have the limiting groove and the elastic element, that is, when the detection protrusion is at the end position, the detection gear is not axially close to the side wall, and the detection protrusion is still stretched out at this time, and the developing cartridge in this state starts from When the image forming device is taken out or reloaded, the detection protrusion bends to avoid the first inner wall of the main body, and the cover is provided with a second gap to prevent the detection protrusion from interfering with the cover when it is elastically deformed, and whether the detection protrusion recovers after bending during this process It is also no longer important to reach the extended state, so the requirements for the elasticity of the detection protrusion are also lower.

Embodiment 3

[0064] Unless otherwise specified, the developing cartridge used in this embodiment is the same as that in Embodiment 1. In this embodiment, the developing cartridge may not have the limiting groove and the elastic element. At the same time, when the detection protrusion is at the end position, it interferes with the protective cover, so that the detection protrusion is bent, that is, when the detection protrusion is at the end position, the detection gear does not axially approach. The side wall and the protective cover are provided with an interference part at the position opposite to the end of the detection protrusion. The detection protrusion interferes with the protective cover, causing the detection protrusion to bend. At this time, the detection protrusion is no longer detected, so the requirement for the elasticity of the detection protrusion is also low.

Abstract

The invention relates to a development box. The development box comprises a box body, a detection gear and a transmission gear engaged with the detection gear, the detection gear comprises a main gear body and a detection protrusion used for being detected, the detection protrusion moves from an initial position to an end position under driving of the transmission gear, the detection protrusion enables elastic prevention when is contacted to an object, and can recover original position protrusion when does not contact with the object, because that the detection protrusion enables elastic prevention when is contacted to the object, and can recover original position protrusion when does not contact with the object, when the development box is arranged on a printer main body or is moved from the main body, a detection piece can move for prevention when contacts with the object, the development box is difficulty interfered with other parts in the main body for causing damage of the detection piece, so that the problems of detection piece interference or damage due to blocking can be solved.

Description

technical field [0001] The invention relates to a developing cartridge. Background technique [0002] Image forming devices such as figure 1 As shown, it includes a main body 1, the main body 1 includes a first side wall 10, a second side wall 11 and a front cover 12, the developing cartridge is detachably installed in the main body, the developing cartridge contains developer, when the developing cartridge runs out of developer , the front cover 12 is opened, the developing cartridge is removed from the main body 1 of the image forming apparatus, a new developing cartridge is installed in the main body 1, and then the front cover 12 is closed. [0003] In the prior art, a detection piece is arranged on the developing cartridge, and the specific structure is as follows figure 2 As shown, the developing cartridge includes a detection gear 2 and an agitator gear 13. The detection gear 2 includes a toothed section 21, a transition section (toothless section) 22 and a detecti...
