Technical Field

[0001] This utility model relates to the field of food processing tools, specifically to a pizza cutter with an easily detachable blade. Background Technology

[0002] A pizza cutter is a tool that uses a rotating circular blade to cut flat foods, resulting in a neater and more convenient cut compared to a knife.

[0003] However, the connection between the round blade and the handle of a traditional pizza cutter often involves a bearing or shaft, where food residue may get stuck, creating a hard-to-clean area. Simple rinsing may cause the residue to mold. Traditional pizza cutters have this problem of cleaning hard-to-clean areas. In addition, pizza cutters with blade sheaths may cause cuts during manual washing. Pizza cutters with blade sheaths are not easy to clean with dishwashers or other tools, requiring the blade to be disassembled. The disassembly process may require auxiliary tools, making the disassembly process more difficult.

[0004] Therefore, it is necessary to invent a pizza cutter with an easily detachable blade to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pizza cutter with an easily detachable blade, thus solving the problem that pizza cutters with blade sheaths are not easy to clean using dishwashers or other tools during actual use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pizza cutter with an easily removable blade includes a mounting block. A blade sheath is detachably mounted on one side of the mounting block. A pull-out pin is engaged with the inner side of the blade sheath. The pull-out pin is detachably mounted at the axis of the cutting blade. A limit block is provided on the inner side of the blade sheath. A dust cover that engages with the limit block is inserted on the outer side of the cutting blade. A guide arc is provided on the inner side of the limit block. A locking protrusion for fixing the pull-out pin is provided at the end of the guide arc.

[0007] As a preferred embodiment of this utility model, the dust cover is provided with an isolation plate on the side near the plug-in post, and a guide edge is provided on one side of the isolation plate for the insertion of the limiting plug. The end of the guide edge is provided with a limiting slot. A guide arc is also provided on one side of the isolation plate that can fit with the plug-in post. A snap-fit ​​protrusion is provided on the side of the isolation plate for clamping the plug-in post.

[0008] As a preferred embodiment of this utility model, the bottom end of the dust cover is provided with a support base, one end of the mounting block is connected to a handle, and the end of the handle is connected to a base; when the support base and the base are placed horizontally, the handle is in a suspended state.

[0009] As a preferred embodiment of this utility model, the plug-in post includes a primary guide post and a secondary guide post, and the end face of the isolation plate can fit with the primary guide post; when the dust cover is closed, the arc surfaces of the first guide arc and the second guide arc can fit with the cylindrical surface of the secondary guide post.

[0010] As a preferred embodiment of the present invention, a polygonal insert is provided on one side of the blade sheath. The polygonal insert is generally conical. An installation slot for inserting the polygonal insert is provided on the inner side of the mounting block. A locking hole for fixing the polygonal insert is provided on one side of the installation slot.

[0023] The cylindrical surface of the grip 1 is equipped with anti-slip stripes. The anti-slip stripes optimize the user experience.

[0024] This invention features a limiting block 302 on the inner side of the blade sleeve 3. The inner side of the limiting block 302 has a locking protrusion 304 to prevent the insertion post 6 from loosening. The locking protrusion 304 constrains the cutting blade 5, preventing it from separating from the blade sleeve 3 during rotation. When cleaning the cutting blade 5, the insertion post 6 is separated from the locking protrusion 304, eliminating the need for traditional threaded connections and allowing for quick disassembly via manual insertion and removal. Furthermore, the dust cover 4, when inserted, is secured by the limiting block 302 pressing against the isolation plate 405. The other end of the isolation plate 405 is in contact with the primary guide post 601, preventing the dust cover 4 from falling off and protecting it from moisture corrosion that could cause rust on the cutting blade 5.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
