Detailed Description

For clarity of explanation of the aspects of the present utility model, preferred embodiments are given below in detail with reference to the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the application or uses of the present disclosure. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

As shown in fig. 1 to 3, the airless sprayer with a filtering device provided by the utility model comprises a bracket 1, a host machine 2 arranged on the bracket 1, a plunger pump 3 arranged in the host machine 2, and a filtering device 4 connected with the plunger pump 3, wherein the filtering device 4 comprises a shell 41, a filter screen bracket 42 arranged in the shell 41, and a filter screen 43 sleeved outside the filter screen bracket 42, and a material inlet 411 and a material outlet 412 are arranged on the shell 41. The bracket 1, the host 2 and the plunger pump 3 in the utility model all belong to the mature prior art, and the specific structure and the working principle are not repeated here. The utility model is mainly improved in that the filtering device 4 is used for filtering impurities in materials and impurities in water mixtures, so that the materials are purer and more flexible to use. The filter screen support 42 can support the filter screen 43, so that the filter screen 43 is not easy to deform, the filtering effect is improved, and blockage is not easy to occur. According to the utility model, the material enters from the material inlet 411 at the lower part of the filtering device 4, then enters into the space between the filter screen 43 and the filter screen bracket 42, then passes through the filter screen 43 to be converged to the material outlet 412, and finally the filtered material is discharged from the material outlet 412 to enter into a high-pressure pipeline.
