Description

Flushing type toilet Technical Field The utility model relates to the field of bathrooms, in particular to a flushing toilet. Background In the technical field of the existing sanitary ware, a flushing toilet is a common product type, and the working principle of the flushing toilet is mainly based on the gravity impact force of water flow to realize the discharge of dirt. Specifically, when the water in the water tank is released, the water flow impacts the dirt in the toilet bowl at a certain speed and pressure under the action of the gravity of the water flow, and the dirt is pressed into the dirt inlet, so that the discharging process is completed. Compared with a siphon toilet, the design is simpler and clearer in structure and working principle, and easy to understand and maintain. During use of a flushable toilet, dirt floating on the water seal surface is a common cleaning challenge. When the water flow output by the brushing holes flows along the inner wall surface of the urinal for brushing, the impact force of the water flow can be dispersed and weakened in the process of gradually reducing the water quantity. Such dispersed water flow impact forces have difficulty in effectively flushing all of the floating soil into the trapway and out of the toilet. Thus, these floating contaminants are liable to remain on the inner wall or surface of the urinal, resulting in failure of the toilet to complete cleaning at one time. To thoroughly remove these residual contaminants, the user typically needs to initiate a secondary flush. The condition that the flushing needs to be performed for many times not only increases the consumption of water resources, but also reduces the use convenience of the closestool, and is not beneficial to water saving and environmental protection. Disclosure of utility model Aiming at the technical problems in the prior art, the utility model provides a flushing toilet, which greatly improves the flushing effect on floating dirt through structural improvement. The utility model solves the technical problems by adopting the technical scheme that the flushing toilet comprises a toilet seat, wherein the toilet seat comprises a urinal and a sewage drain pipe, a water seal area is formed at the bottom of the urinal, one end of the sewage drain pipe is communicated with the water seal area, a brushing hole for flushing the inner surface of the urinal is formed at the top of the urinal, a diving hole is further formed in the urinal, the water outlet direction of the diving hole is downwards along the inner wall of the urinal so as to flush the water seal area, and the diving hole and the brushing hole are configured so that the diving hole is earlier than the brushing hole. In a preferred embodiment, the toilet seat further comprises a flushing water channel, the diving hole and the brushing hole are communicated with the flushing water channel, and the constructional configuration comprises that the orifice position of the diving hole is lower than the orifice position of the brushing hole, so that water flow entering the flushing water channel preferentially flows to the diving hole under the action of gravity.
