The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
As shown in fig. 1, the present embodiment provides a drug-adding lift pump negative pressure device, which includes:
the device comprises a vertically arranged upper liquid pipe 1, wherein the water inlet end of the upper liquid pipe 1 is connected with a check valve 2;
the liquid storage tube 3 is vertically arranged, the upper end and the lower end of the liquid storage tube 3 are respectively connected with an upper end cover 4 and a lower end cover 5 for sealing, and the upper end cover 4 and the lower end cover 5 are respectively connected with the liquid storage tube; the water outlet end of the upper liquid pipe 1 is communicated with the top of the liquid storage pipe 3, and specifically, the upper liquid pipe 1 is communicated with the pipe wall of the liquid storage pipe 3 close to the upper end cover 4;
