Description

Technical Field

[0001] This utility model relates to the field of oil press technology, specifically to an oil press that is easy to clean. Background Technology

[0002] An oil press is a mechanical device used to extract oil from oilseed crops. Based on different working principles and application scenarios, oil presses can be divided into various types. An oil press uses the rotation of a screw to squeeze the oilseeds, separating the oil from the solid parts. With technological advancements, new oil presses have significantly improved in efficiency, intelligence, and environmental friendliness, meeting the needs of different users. However, existing oil presses that are easy to clean still have certain drawbacks; for example:

[0003] The patent application CN202322667336.0, entitled "An oil press that is easy to clean", includes an oil press body, a pressing chamber and a feeding hopper, wherein the bottom of the feeding hopper passes through the top of the oil press body and is fixedly connected to the top of the pressing chamber. This invention, by incorporating a cleaning casing, a cleaning agent box, a cleaning agent rod, and a nozzle, allows users to easily clean the pressing chamber after pressing oil. They can first observe the approximate location of oil stains through the observation slot and then spray the cleaning agent onto the pressing chamber using the nozzle. This solves the problem of oil presses lacking cleaning devices after pressing, leading to oil residue buildup. While this type of easy-to-clean oil press is functional, it lacks the ability to collect oilseeds uniformly during pressing, hindering the filtration of impurities. Furthermore, it prevents quick disassembly, replacement, or cleaning of key components during maintenance, increasing the user's workload and hindering routine maintenance, often causing inconvenience.
