Abstract: A method for emptying the rectum by using an electronic sanitary appliance arranged on a toilet, comprises: extending out a rectum flushing nozzle so that it locates underneath of the anus of a user who is seated on the toilet; spraying a first linear water flow to the anus from the rectum flushing nozzle, modifying the relative position between the rectum flushing nozzle and the user's anus so that the first linear water flow aims at the anus; spraying the anus with a second linear water flow from the rectum flushing nozzle to pass through the anus and into the rectum; spraying continuously the second linear water flow and stopping spray of the second linear water flow when the user has a desire to defecate, then the user discharges the substance in the rectum.
Abstract: A permanent-magnet synchronous motor of a draining pump is disclosed. It includes a permanent-magnet rotor for driving an impeller to rotate, a pump body for supporting the permanent-magnet rotor, a stator core and a stator coil. Among which, the stator coil is constructed with an enamelled aluminum wire winding which is coiled by an enamelled aluminum wire and sealed in a container. The invention applies the enamelled aluminum wire to the permanent-magnet synchronous motor of a draining pump. The winding of the stator coil and a welding part of its lead-out wire are sealed with plastic or epoxy resin which effectively isolate them from outside air, especially damp air. Therefore, the invention prevent the enamelled aluminum wire winding of the stator coil and the welding part of its lead-out wire from being oxidized in air and being corroded by the moisture, acid or alkaline matter in damp air.
Abstract: A pump assembly constructed to allow unloaded starting of the pump. The assembly includes a pump body, a permanent magnet rotor, a rotor shaft, a pump cover, a shaft sleeve and an impeller. The impeller includes a holding chamber for holding the shaft sleeve which is arranged proximate a center of the impeller. A stopping rib extends inwardly from an internal wall of the holding chamber of the impeller. The shaft sleeve includes a tubular body with a starting rib extending laterally from the body. During operation of the pump, the starting rib interferes with the stopping rib. A number of shock absorbing pads are disposed between the starting rib and the stopping rib and maintained thereat by a notch and ridge association that extends along each rib and pad. The pump includes a space that allows rotation of the starting rib relative to the stopping rib which provides unloaded starting of the pump.
