[0023] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the utility model: a filtering structure for a sprayer;

[0024] It includes a liquid storage barrel 1 and a filter assembly 4. A threaded inlet 2 is installed through the top of the liquid storage barrel 1. The filter assembly 4 is installed inside the threaded inlet 2. The filter assembly 4 is used to filter the liquid added to the liquid storage barrel 1. The filter assembly 4 includes a filter shell 5, a limiting ring 6 and a filter screen 7. The filter shell 5 is located inside the threaded inlet 2. The limiting ring 6 is installed on the inner side of the bottom of the filter shell 5. The filter screen 7 is placed on the top of the limiting ring 6. A support ring 8 is installed on the top of the filter shell 5. The support ring 8 is located above the threaded inlet 2.
