Description

Odor-removing closestool with integrated split air duct structure Technical Field The invention relates to the technical field of bathrooms, in particular to a deodorizing closestool with an integrated split air duct structure. Background The odor generated during the use of toilets, in particular toilets, is one of the core problems affecting the comfort of living and public environment sanitation. The peculiar smell gas mainly comes from the mixed liquid surface of excrement and water, and the main components of the peculiar smell gas are volatile substances such as ammonia, hydrogen sulfide and the like. If the peculiar smell cannot be removed effectively in time, not only the user experience is poor, but also bacteria can be bred, and the indoor air quality can be influenced. Thus, improving the odor removal capability of toilets has become an important direction of continued attention and innovation in the sanitary ware field. In the prior art, in order to solve the problem of toilet odor, various technical schemes have been proposed, and the following main categories can be summarized: The first category of solutions focuses on physical masking or chemical neutralization, such as adding a fragrance or deodorant to a toilet tank or accessory. The method belongs to passive treatment, can not eliminate peculiar smell from the root, can only mask smell, has limited effect duration, needs to replace consumable materials frequently, and is not ideal in user experience and maintenance cost. The second scheme adopts active exhaust technology, namely, an exhaust device is externally connected on the structure of the closestool. The common practice is to arrange an air suction port at the rear part of the closestool and connect a fan to pump out the air in the closestool. Such methods, while achieving active deodorizing, still have significant drawbacks in practical applications. Firstly, most designs adopt a single air suction inlet, the suction action range is limited, and an air flow dead angle is easily formed in the toilet bowl liner, so that peculiar smell released from the edge of the bowl liner or a position far away from the air suction inlet cannot be effectively captured in time, and the odor purifying efficiency is unbalanced. And secondly, the diffusion characteristic of natural rising of the peculiar smell gas is not fully considered in part of design, the position of the air suction inlet is not reasonable, the early interception of the peculiar smell source can not be realized, the peculiar smell is sucked away after being diffused and diluted in a larger space of the basin liner, the treatment efficiency is reduced, and the load and the energy consumption of a fan are increased. Furthermore, some integrated air ducts have complex structures, poor combination degree with the toilet main body, air leakage risk, or damage the integrity and the aesthetic degree of the appearance of the toilet due to the external and spliced installation mode, and in addition, the structure of the integrated air duct may also have the risk that liquid splashes into the air duct during flushing. Disclosure of Invention In view of the above, the embodiment of the invention provides an odor-removing toilet with an integrated split air duct structure, which solves or improves the technical problems in the prior art. The technical scheme of the embodiment of the invention is realized in such a way that the odor removing closestool with the integrated split air duct structure comprises: A toilet body having an integrated installation chamber formed at an inner bottom thereof; The air duct component is arranged along the upper part of the inner side wall of the bowl liner of the closestool body, and an air suction inlet of the air duct component is positioned in the upper area of the flushing opening of the bowl liner of the closestool body along the gravity direction and is used for collecting and guiding peculiar smell gas generated in the closestool; the exhaust fan is arranged in the front side area inside the mounting cavity, an air inlet of the exhaust fan is communicated with the bottom of the air duct assembly and is used for generating suction power, continuously extracting and pressurizing the peculiar smell gas collected by the air duct assembly and outputting the peculiar smell gas; The exhaust assembly is arranged in the installation cavity, the air inlet end of the exhaust assembly is communicated with the air outlet end of the exhaust fan, and the air outlet end of the exhaust assembly extends outwards from the installation cavity and penetrates out of the toilet body and is used for directionally discharging air treated by the exhaust fan to the atmosphere outside the toilet. As an improvement, the air duct assembly includes: the annular air duct is of an annular structure with a hollow circular section and is integrally formed at the upper part of the inner side wall of the bowl liner of the closestool bod
