[0022] In order to clearly illustrate the scheme in the utility model, preferred embodiments are given below and described in detail with reference to the accompanying drawings. The following description is essentially only exemplary and is not intended to limit the application or use of the present disclosure. It should be understood that in all the drawings, corresponding reference numerals represent the same or corresponding parts and features.
[0023] like Figures 1 to 9As shown, the utility model provides a sprayer with a square liquid storage box, including a base 1, a liquid storage box 2 installed on the top of the base 1 and a plunger pump 3 installed in the base 1, the liquid storage box 2 includes a square box body 21 opened at the top and a square box cover 22 covering the entire top of the box body 21, the corner of the box body 21 is a large arc transition structure, the top of the base 1 forms a square cavity 11, and the liquid storage box 2 is inserted into the square cavity 11. The plunger pump 3 in the utility model can adopt a commercially available product, and the structure and working principle are not repeated. The box body 21 in the utility model is an open-top structure, that is, the box body 21 has no top structure, and is only composed of surrounding walls and a bottom wall. The corner of the box body 21 adopts a large arc transition structure, thereby reducing the cleaning dead angle and facilitating the cleaning of the box body 21. The open structure further reduces the cleaning dead angle and is also convenient for cleaning the inside of the box body 21. The box cover 22 can close the top of the box body 21 and is also convenient for adding materials.
