Description

Technical Field

[0001] The utility model relates to a cap mounting structure of a toner bottle. Background Art

[0002] A toner bottle is a consumable used on a printer. Users need to supplement toner into the toner bottle according to the printer's prompts and then reinstall the toner bottle for use. Currently, toner bottles on the market include a toner bottle body and a cap. Users need to open the cap to supplement toner into the toner bottle. However, the connection structure design between the toner bottle body and the cap on the market at present is not reasonable enough, resulting in easy damage to the cap when opening.

[0003] Therefore, it is necessary to further improve the cleaning table. Summary of the Utility Model

[0004] To solve the above problems, the utility model proposes a cap mounting structure of a toner bottle. When the toner bottle adopting this mounting structure replenishes toner, the cap can be avoided from being damaged.

[0005] The utility model proposes a cap mounting structure of a toner bottle, which includes a toner bottle body and a cap. An annular step is provided on the outer peripheral side of the toner bottle body at its bottle mouth. An inclined chamfer structure or a rounded corner structure is provided on the upper outer edge of the annular step. The cap is covered on the bottle mouth end of the toner bottle body and has a cap wall sleeved on the bottle body of the toner bottle. A plurality of elastic clamping parts are circumferentially and evenly distributed on the cap wall of the cap. The elastic clamping parts are used for clamping the bottom end of the annular step to prevent the toner bottle body from loosening. An out-powder port is provided on the side wall of the cap and is arranged close to the top end of the cap. The bottle mouth extends towards the top end direction of the cap.

[0006] In one or more embodiments, a plurality of circumferentially evenly distributed avoidance openings are provided on the cap wall of the cap. Elastic plates extending downward are provided on the avoidance openings, and the elastic clamping parts are arranged on the inner side surface of the elastic plates.

[0007] In one or more embodiments, a detachable sealing part is provided at the outer side position of the cap where the out-powder port is located.

[0008] In one or more embodiments, a spiral groove is provided on the outer wall of the toner bottle body from bottom to top.

[0009] In one or more embodiments, a plurality of connecting parts are provided on the spiral groove, and the plurality of connecting parts are evenly distributed along the spiral groove.

[0010] In one or more embodiments, a plurality of vertically distributed positioning convex parts are provided on the cap wall of the cap.

[0011] Compared with the prior art, this solution has the following beneficial effects: the connection between the carbon powder bottle body and the cover body is achieved by snap-fitting, which has the advantage of easy installation; when disassembling, it is only necessary to gently pry open the elastic clamp to separate it from the annular step. Since disassembly is relatively simple, the possibility of damage is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a cross-sectional view of the connection between the carbon powder bottle body and the cover body of this embodiment;

[0013] Figure 2 It is a schematic diagram of the three-dimensional structure of the carbon powder bottle body and the cover body of this embodiment. DETAILED DESCRIPTION

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

[0015] Please see attached Figure 1-2 The utility model provides a bottle cap installation structure for a toner bottle, which comprises a toner bottle body 1 and a cover body 2. The outer peripheral side of the toner bottle body at the bottle mouth is provided with an annular step 3, and the outer edge of the upper end of the annular step is provided with a chamfered angle structure or a chamfered foot structure. The cover body 2 is provided on the bottle mouth end of the toner bottle body 1, and has a cover wall sleeved on the bottle body of the toner bottle body. The cover wall of the cover body 2 is evenly distributed with a plurality of elastic clamping parts 4 in the circumferential direction, and the elastic clamping parts are used to clamp the bottom end of the annular step 3 to prevent The carbon powder bottle is loose. When installing, the cover is covered on the carbon powder bottle from top to bottom. After the elastic clamp contacts the upper end of the annular step, it is gradually squeezed outward by the annular step until the elastic clamp is clamped into the bottom end of the annular step to complete the installation. Since the outer edge of the upper end of the annular step is provided with a chamfered angle structure or a rounded foot structure, the elastic clamp will be more easily clamped with the annular step. The side wall of the cover 2 is provided with a powder outlet 5, which is arranged near the top of the cover, and the bottle mouth extends toward the top of the cover. When disassembling, the user uses a screwdriver to tilt the elastic clamp outward to disengage it from the bottom end of the annular step, and then lifts the cover upward.

[0016] The cover body 2 has a cover wall provided with a plurality of circumferentially evenly distributed avoidance openings, on which an elastic plate 6 extending downward is provided. The elastic clamping portion 4 is provided on the inner side of the elastic plate. The avoidance openings allow the elastic plate to deform outward, so that the elastic clamping portion can be more easily clamped into the bottom end of the annular step.

[0017] The cover body 2 is provided with a detachable sealing portion 7 at the outer side of the powder outlet 5, and the powder outlet is exposed by removing the sealing portion.

[0018] The outer wall of the toner cartridge body 1 is provided with a spiral groove 8 from bottom to top. The spiral groove is conducive to the export of the toner inside the toner cartridge body. A number of connecting parts 9 are provided on the spiral groove, and the number of connecting parts are evenly distributed along the spiral groove. The connecting parts can strengthen the structural strength of the toner cartridge body and make it not easily deformed.

[0019] A number of vertically distributed positioning convex parts 10 are provided on the cover wall of the cover body 2. The positioning convex parts can be used for alignment when the toner cartridge is installed in the printer.

[0020] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present invention should be included in the protection scope recorded in the claims.
