At present, there are many pests such as bad smell and breeding of bed bugs in the sewage pipes of toilets. Everyone only pays attention to organic chemical environmental pollution such as benzene and indoor formaldehyde. The biological invasion of infectious viruses such as SARS and avian flu epidemics in the sewage pipes is also very harmful. The very core direct-to-enclosed deodorant floor drain adopts the basic principle of pedal-operated force in the opposite direction, and automatically adjusts the opening and closing of the deodorant sealing gasket with the force of the running water itself. It does not need an exhaust valve, which prevents the secondary pollution of the exhaust valve-type floor leak seal drying up and the spoilage of the existing waste water and mildew. Concrete silicone seals are installed between each cooperating component, so that odors and pests cannot enter the room. The safety channel of the drainage pipe is straight-through, there is no block, it is not easy to be blocked, and the discharge volume is twice that of the traditional deodorant floor drain. Due to the force-tightness, the characteristics are smooth and all normal service life is permanent. The deodorant inner core is screw-on type, which is very easy to remove, and the cleaning is very convenient and hygienic.
The very core direct closed deodorant floor drain has obtained the national invention patent patent, the Beijing Construction Commission High-tech Brand Promotion 2307-0107, and has been used in large and medium-sized construction projects such as the National Stadium for the 2008 Beijing Olympic Games, and exported to overseas, and has been unanimously recognized by customers.
