[0027] Referring to Figures 1-5 , a toilet bowl, comprising a ceramic body, a cover plate 100 and a spray head assembly 200, the ceramic body has a toilet bowl 300, the middle and lower part of the toilet bowl front wall 310 is an abnormal defecation area 400, the spray head assembly 200 is located below the cover plate 100 and is fixed to the cover plate 100, the spray head assembly 200 comprises a water inlet pipe 210, a water pipe elbow 220 and a booster spray head 230, one end of the water pipe elbow 220 is connected with the water inlet pipe 210, the other end is connected with the booster spray head 230, the booster spray head 230 is located at the top of the rear side of the toilet bowl 300, and the spray head faces the abnormal defecation area 400.

[0028] The shower head assembly 200 is installed below the cover plate 100, the water inlet pipe 210, the water pipe elbow 220 and the pressure boosting spray head 230 are communicated, a water flow passage is formed, when it is detected that the shower head needs to be opened, the core controls water flow, the water flow passes through the water inlet pipe 210 and the water pipe elbow 220, reaches the pressure boosting spray head 230, the water flow is boosted to flush the abnormal falling toilet area 400, the effect of completely cleaning the toilet bowl 300 is achieved, the use experience of the user is improved, and the user pain point of residual dirt is solved.

[0029] In some embodiments of the utility model, refer to Figure 4 The pressure boosting spray head 230 is provided with a plurality of spray holes 231, the spray holes 231 are sequentially divided into a contraction section 234, a throat section 235 and a diffusion section 236 from a water inlet end 232 to a water outlet end 233, the hole diameter of the contraction section 234 gradually decreases from the water inlet end 232 to the throat section 235, and the hole diameter of the diffusion section 236 gradually expands from the throat section 235 to the water outlet end 233. The water inlet end 232 is the inlet of the contraction section 234, and the water outlet end 233 is the outlet of the diffusion section 236. According to fluid mechanics, the spray holes 231 change the speed and pressure of the water flow by changing the internal hole diameter of the spray holes 231 based on the Laval pressure boosting principle, and finally obtain high-speed water flow, which can achieve good cleaning effect on the abnormal falling toilet area 400.

[0030] In some embodiments of the utility model, the pressure boosting spray head 230 is further provided with a water inlet cavity 237, the water inlet ends 232 of all the spray holes 231 are communicated with the water inlet cavity 237, the inner peripheral wall of the water inlet cavity 237 is provided with a first thread 238, and the other end of the water pipe elbow 220 is screwed into the water inlet cavity 237 through the first thread 238.

The pressure boosting spray head 230 and the water pipe elbow 220 are screw-connected, so that the parts can be conveniently repaired or replaced later.

[0031] In some embodiments of the utility model, the shower head assembly 200 further comprises a sealing ring 240, the sealing ring 240 is arranged in the water inlet cavity 237, and the other end of the water pipe elbow 220 is screwed into the water inlet cavity 237 and abuts against the inner wall of the water inlet cavity 237. The sealing ring 240 prevents water from leaking out of the connection between the pressure boosting spray head 230 and the water pipe elbow 220.

[0032] In some embodiments of the utility model, the hole diameter of the water inlet end 232 is greater than that of the water outlet end 233. The relatively small hole diameter of the water outlet end 233 helps to further control the speed and direction of the water flow, optimizes the energy conversion process of the whole shower head, avoids loss of kinetic energy and improves the efficiency of kinetic energy output.

[0033] In some embodiments of the utility model, the ratio of the aperture of water inlet end 232 to the aperture of throat section 235 is (4-6):1. For example, the aperture of water inlet end 232 is 5mm, the length of contraction section 234 is 7mm, the aperture of throat section 235 is 1mm, and the length is 1.2mm, so that stronger cleaning strength can be achieved.

The included angle α determines the jet direction of booster jet head 230, and α between 130° and 160° ensures that booster jet head 230 can jet to the front wall of toilet bowl 300.

[0036] In some embodiments of the utility model, water pipe elbow 220 further comprises third pipe section 223, second pipe section 222 and third pipe section 223 are connected to the two ends of first pipe section 221 respectively, the included angle β between the two axes of first pipe section 221 and third pipe section 223 is 130°-160°, so that water pipe elbow 220 as a whole has a bridge shape. Third pipe section 223 is inclined downwardly curved relative to horizontal first pipe section 221, and when connected with water inlet pipe 210, it can avoid cover plate 100.

[0037] In some embodiments of the utility model, referring to Figure 5 , the outer bottom of cover plate 100 is provided with annular support 500 for fixing water pipe elbow 220, annular support 500 is fixedly connected with cover plate 100, and annular support 500 is sleeved on first pipe section 221.
