It can collect and treat domestic water in the bathroom. It is usually an integrated system that can solve public health problems in some special places. Fully automatic sewage lifts are mainly used to remove sewage from sanitary ware in basements and places far away from drainage risers that do not have gravity discharge of sewage. It can also be used in places such as ships and vehicles where drainage conditions are not very good.

[0003] When installing existing sewage lifting products, such as Figure 1 As shown, during external installation, the lower end of the outlet pipe a7 is threadedly connected and installed at the top outlet of the outlet elbow a2, and fixed with a locking nut a6 to complete the external installation of the outlet pipe a7. During internal installation, two mounting holes 1 (size Φd) are provided on the inclined surface of the water tank a8, and mounting hole 2 (size Φd) is also provided on the inclined surface of the water outlet elbow a2. The water outlet elbow a2 equipped with the water outlet pipe a7 is aligned and installed on the internal inclined surface of the water tank a8, so that the mounting holes 1 and 2 of the two are aligned; there is also mounting hole 3 (size Φd) on the pressure plate a3, and sealant a5 is evenly coated on a plane of the pressure plate a3, and the pressure plate a3 coated with sealant a5 is attached to the outside of the water tank a8, and the mounting holes 1, 2 and 3 are aligned; fasteners a4 are passed through the above-mentioned mounting holes to fasten the pressure plate a3, the water tank a8 and the water outlet elbow a2, and the sealing is completed after the sealant a5 on the pressure plate a3 solidifies; finally, the sewage pump a1 is hung on the water outlet elbow a2 to complete the internal installation.

The utility model designs a cylindrical boss 5 inside the water tank 4, and the water outlet elbow 2 is mounted on the cylindrical boss 5 when in use. The cylindrical boss 5 and the water tank 4 are both made by rotational molding, and the production and manufacturing are simple; and the installation is also simple and easy to master when in use.

[0042] Specifically, according to Figure 2-11 As shown, a sewage lifting device includes: a water tank 4, the inner wall of which is provided with a plurality of cylindrical bosses 5 at intervals, the cylindrical bosses 5 are used to install a water outlet elbow 2, the two ends of the water outlet elbow 2 are respectively connected to a sewage pump 1 and a water outlet pipe 3; the sewage pump 1 is detachably arranged at the bottom of the water tank 4.
