Description

Technical field

[0001] The utility model relates to a powder stirring structure of a carbon powder cartridge. [Background Technology]

[0002] Toner cartridges are storage containers used to supply developer, for example, to laser copiers. Typically, these cartridges are removably installed in the copier's developer unit. Existing toner cartridges typically incorporate an internal agitator to prevent toner accumulation and ensure proper toner delivery. However, after a period of use, the agitator requires replacement due to wear. However, currently available toner cartridges have an integrated agitator mechanism, requiring replacement as a whole, resulting in high replacement costs.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems and provide a powder stirring structure for a carbon powder cartridge, which can reduce the cost of subsequent replacement and maintenance.

[0005] To achieve the above-mentioned purpose, we provide a powder stirring structure for a carbon powder cartridge, which includes a cylinder with a powder storage chamber formed inside, a transmission gear group and a powder replenishing port respectively provided at both ends of the cylinder, a stirring shaft provided inside the cylinder, one end of the stirring shaft is connected to the transmission gear group, and the other end of the stirring shaft is pivotally connected to the shaft hole located at the powder replenishing port, and a plurality of connecting plugs are axially distributed on the stirring shaft, and the plurality of plugs are arranged at intervals.

[0006] In one or more embodiments, the plug includes a first connecting portion and a head, the first connecting portion connects the head and the stirring shaft respectively, the head is trapezoidal or truncated cone-shaped, and the head, the first connecting portion and the stirring shaft are an integral injection molding structure.

[0007] In one or more embodiments, the transmission gear set includes a driving gear and a driven gear that mesh with each other, the driven gear has a second connecting portion extending into the powder storage chamber, and the stirring shaft is connected to the second connecting portion in a linkage manner.

[0008] In one or more embodiments, the second connecting portion has an elastic hook, the stirring shaft has an axial cavity sleeved with the second connecting portion, and a bayonet connected to the elastic hook is provided in the axial cavity.

[0009] In one or more embodiments, a powder outlet is provided on the side wall of the cylinder, and a cover plate is provided on the powder outlet. The cover plate can move relative to the cylinder to open the powder outlet.

[0010] Compared with the background technology, the present invention has the following technical effects: the powder stirring structure is installed and connected by arranging multiple plugs on the stirring shaft. The stirring paddle can be removed and replaced after the stirring paddle is worn, without replacing the stirring shaft, reducing the accessories that need to be replaced, thereby reducing costs.

[0013] Figure 3 This is a structural diagram of the driven gear and the stirring shaft of the utility model. [Specific implementation method]

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0015] Please see Figure 1-3 The present application provides a powder stirring structure of a carbon powder cartridge, which includes a cylinder 1 with a powder storage chamber formed inside. A transmission gear group and a powder replenishing port 2 are respectively provided at both ends of the cylinder. The user can replenish carbon powder into the powder storage chamber through the powder replenishing port. A stirring shaft 3 is provided inside the cylinder, one end of the stirring shaft is connected to the transmission gear group, and the other end of the stirring shaft is pivotally connected to the shaft hole located at the powder replenishing port. A plurality of connecting plugs 4 are axially distributed on the stirring shaft 3, and the plurality of plugs are arranged at intervals. The plugs are used to connect a stirring paddle for stirring the carbon powder. When the stirring paddle is worn and cannot stir the carbon powder well, the stirring paddle can be pulled out and replaced to reduce the later use cost.

[0016] The plug 4 includes a first connecting portion 41 and a head 42. The first connecting portion connects the head and the stirring shaft respectively. The head is trapezoidal or truncated cone-shaped, which can avoid the problem of the stirring paddle falling off during use. The head 42, the first connecting portion 41 and the stirring shaft 3 are an integral injection molding structure.

[0017] The transmission gear set includes a driving gear 5 and a driven gear 6 that mesh with each other. The driven gear has a second connecting portion 7 that extends into the powder storage chamber. The stirring shaft is linked to the second connecting portion. Specifically, the second connecting portion has an elastic hook 71, and the stirring shaft 3 has an axial cavity 8 that is sleeved with the second connecting portion. A bayonet 81 connected to the elastic hook is provided in the axial cavity. During installation, the elastic hook 71 extends into the axial cavity until it is engaged with the bayonet. At this time, the axial cavity is matched with the second connecting portion to complete the installation.

[0018] A powder outlet 9 is provided on the side wall of the cylinder 1, and a cover plate 10 is provided on the powder outlet. The cover plate can move relative to the cylinder to open the powder outlet. The cover plate is connected to the cylinder in a snap-fit ​​manner to facilitate users to open the cover plate.

[0019] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
