[0018] The working principle of the present invention is introduced as follows: the main body of the bedpan cleaning toilet used in households and nursing homes is composed of an outer shell and an inner tank. The upper cover is opened when the bedpan is placed or the toilet is used, and is closed during daily idleness or cleaning work. The flip base is used to support and fix the bedpan, and can be flipped to a certain tilted angle under the drive of compressed air or a motor to maintain the tilt. After flipping into place, the multifunctional cleaning nozzles located on all sides of the bedpan spray high-pressure water flow or compressed air and heated compressed air according to program instructions to flush, clean and dry the bedpan. The multifunctional cleaning nozzle is located above the bedpan and has a certain incident angle, mainly cleaning and draining the inner wall surface of the bedpan, and the multifunctional cleaning nozzles on both sides are used to clean and drain the feces. The functional cleaning nozzle sprays the sides of the toilet bowl, and the multifunctional cleaning nozzle at the rear of the toilet bowl cleans its back and bottom, thereby ensuring that the toilet bowl is cleaned simultaneously and efficiently. The flip base is designed with a special structure so that the toilet bowl can be raised as much as possible without blocking the cleaning part of the toilet bowl. There is a gap between the toilet bowl and the flip base to facilitate flushing with water, and the flip base is stably connected to the toilet bowl through a special buckle design without falling off or loosening. When the cleaning is completed, the flip base drives the toilet bowl to reset. After opening the upper cover, press the toilet bowl buckle with your thumb, the bayonet piece will move, and the base fixing hole will be loosened to remove the toilet bowl from the flip base. The operation can be completed with one hand.

[0019] The beneficial effects of the present invention are introduced as follows:

[0020] (1) This product can be used independently as a toilet. The potty can be removed and used in other environments. One product can also correspond to multiple potties. The used potty can be placed directly on the flip base, the upper cover can be closed and the product can be started with one button. The specific program can be set to 2 to 4 minutes (the specific time for each section can be set through the controller) to complete the flushing. After opening the cover, replace the potty and continue cleaning.

[0021] (2) This product has an automated control program design and multiple cleaning modes. On the operation panel, there are one-touch selections for programs such as "feces cleaning", "urine cleaning", and "inner cavity cleaning", which can quickly complete cleaning.

[0022] (3) The flip base has a large open structure design with an opening, which cooperates with the support tops designed on each surface to support the bottom of the toilet bowl, so that the contact area between the two is minimized, thereby achieving full surface coverage of the toilet bowl and significantly improving the cleaning effect and cleaning completion.

[0023] (4) The multi-functional cleaning nozzle can spray pressure water flow, compressed air, and compressed hot air respectively according to the instructions of the control system. The direction of the nozzle can be manually adjusted within a certain range, and the position is reasonably set. There is a multi-functional cleaning nozzle located on the upper side of the inner cavity of the toilet bowl. The water flow is large, which can assist in the dumping of feces in the toilet bowl and the cleaning of the inner cavity. On both sides of the inner wall of the main body, there are corresponding multi-functional cleaning nozzles along the inclined direction of the toilet bowl to spray and wash the side of the toilet bowl. The multi-functional cleaning nozzle at the rear of the toilet bowl cleans its back and bottom, so as to ensure that the cleaning work of the toilet bowl can be completed simultaneously and efficiently.

[0024] (5) The structure of the toilet bowl and the design of the flipping base conform to the adaptation design concept. The base fixing holes at the rear end of the toilet bowl and the buckle pieces and toilet bowl buckles on the back plate of the flipping base enable the toilet bowl to be buckled on the flipping base with one hand firmly and stably without slipping during the tilting process. After the cleaning is completed, the toilet bowl can also be conveniently removed with one hand, and the process is convenient and easy to use. Description of the Drawings
