Description

Waste powder collecting device and image forming apparatus Technical Field The utility model relates to the technical field of printing consumables, in particular to a waste powder collecting device and image forming equipment. Background Image forming apparatuses such as laser printers, copiers, and the like, which relate to products of powder cartridges, are generally provided with a device for collecting waste powder, simply referred to as a waste powder cartridge. The waste toner box is an important part in the image forming apparatus, and the capacity of collecting waste toner determines the number of times the waste toner box needs to be replaced in the whole life of the image forming apparatus, and if the number of times of replacement is too large, user experience is affected and related cost is increased. In the existing waste powder box structure, if the shape of the waste powder box is relatively regular, the waste powder box can meet the specification requirements without adding other structures. Under the condition that the space of the waste powder box is relatively large, the waste powder at the powder outlet can uniformly fall on the waste powder box by adding a powder stirring structure such as a screw rod and the like, but the shape of the waste powder box can be influenced by the internal structure of the printer, in order to miniaturize the printer, the waste powder box can be set into an irregular shape, and if the waste powder box is in the irregular shape, the space size of the waste powder box cannot fully utilize the space of the waste powder box and even cannot meet the specified specification when the space size of the waste powder box cannot meet the added powder stirring structure such as the screw rod and the like and the transmission structure. Disclosure of utility model The utility model aims to provide a waste powder collecting device and image forming equipment, which are used for solving the problems in the prior art, and when a waste powder box is in an irregular shape, the space of the waste powder box can still be fully utilized to collect waste powder.
