[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1:
[0030] like Figures 1-4 As shown, the present invention provides a recyclable and environmentally friendly paper funnel, including a paper funnel body 1 and a filter screen 2. The lower end of the paper funnel body 1 is provided with a feeding port 3. A positioning sleeve 4 and a connecting part 5 are fixedly installed on the outer side of the paper funnel body 1. A limiting part 6 is fixedly installed on the outer side of the connecting part 5. A connecting strip 7 is fixedly installed on the upper end of the filter screen 2. A through hole 8 and a waist-shaped groove 9 are provided inside the upper end of the connecting strip 7.
[0031] Specifically, the paper funnel body 1 and the filter screen 2 have a conical structure, with the filter screen 2 fitting snugly against the outer side of the opening of the feed port 3.
