Technical Field

The utility model relates to the field of bathrooms, in particular to a toilet bowl cleaning device and a toilet bowl.

Background

Before the closestool is used, the pan surface of the closestool is dry, the closestool is generally made of ceramic, and the ceramic surface is easy to stain and difficult to clean under the condition of drying. In addition, the pan surface of the closestool possibly has dirt residues after being used, and bacteria are easy to breed. Therefore, currently, some toilets in the prior art use washing water for pre-wetting, and some toilets are provided with a water spraying structure alone for pre-wetting or spraying sterilizing water.

For pre-wetting, there are several solutions in the prior art, for example, chinese patent CN201810367851.8 proposes a pre-wetting nozzle for intelligent toilets, which pre-wets the toilet bowl by making the water flow to swing outwards due to the action of the rotational centrifugal force and to mutually strike into mist water flow during outflow, with less water consumption and better cleaning effect. Another example is chinese patent CN201710118083.8 which proposes a sterilizing water spray device that can reciprocate in a straight direction and spray sterilizing water into the inside of a toilet bowl, and a bidet equipped with the sterilizing water spray device.

The prior art can pre-wet or sterilize the pan surface of the toilet bowl by 360 degrees, but the following problems generally exist:

if the requirements of pre-wetting or disinfection of the far end of the closestool pan surface are met, the near end of the closestool pan surface is easy to generate splash at the periphery due to overlarge water yield, so that secondary pollution is caused, and the use experience is affected; if the water pressure is reduced, although the pre-wetting or sterilizing requirement of the near end of the toilet pan surface is met, the water flow cannot reach the far end of the toilet pan surface, and the pre-wetting or sterilizing requirement cannot be met.
