Detailed Implementation Methods
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.
[0017] It should be noted that in this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.
[0018] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0019] Please see Figures 1 to 5 The present invention relates to a small-scale kitchen waste oil scraping device, comprising an oil-water separation tank 10, wherein a double-plate oil scraping device 20 and an oil guide groove 11 are provided inside the oil-water separation tank 10. The double-plate oil scraping device 20 is located on the side of the oil guide groove 11, and the double-plate oil scraping device 20 includes two W-shaped oil guides 30, which are inclined toward the oil guide groove 11 at an angle of 2°.
