Rotational-flow-structure deodorizing floor drain

Abstract

The invention discloses a rotational-flow-structure deodorizing floor drain. The rotational-flow-structure deodorizing floor drain comprises a floor drain cover, a large filtering net, a small filtering net, a floor-drain-core inner pipe, a floor-drain-core pulling ring, a floor-drain-core shell, a floor drain body and the like, wherein the floor-drain-core inner pipe is matched with the floor-drain-core shell, the floor-drain-core pulling ring is installed in the floor-drain-core shell, the floor-drain-core inner pipe, the floor-drain-core pulling ring and the floor-drain-core shell jointly form a floor drain core, the floor drain core is installed in the floor drain body, then the small filtering net is installed in an installing groove reserved in the top end of the floor-drain-core inner pipe, the large filtering net covers the small filtering net, the large filtering net is installed in an installing groove reserved in the center of the floor drain body, and the floor drain covercovers the floor drain body. According to the rotational-flow-structure deodorizing floor drain, the spiral-wall-structure water draining principle is adopted, water flow is drained through a rotational-flow wall during water draining, and the rotational-flow effect during water draining appears; rotational flow forms negative pressure to improve the water draining effect; meanwhile, the rotational-flow-structure deodorizing floor drain has the multiple-filtering-net structure easy to clean, and it is effectively reduced that as hair falls down on the floor drain core, the water draining performance is influenced.

Description

technical field [0001] The invention relates to a household drainage device, in particular to a deodorant floor drain with a swirl structure. Background technique [0002] In the prior art, the inner tubes of the water-sealed floor drain cores are all smooth walls, and there is a phenomenon of slow drainage. For this reason, the inner tube of a floor drain core is developed as a spiral structure, and when draining, it acts as a drainage effect on the spiral wall, and a swirl effect occurs, increasing the drainage flow rate, and is not easy to be blocked when draining. [0003] The existing floor drain filter structure is basically a single-layer filter, and all the hairs fall off the water seal, causing the water seal to be entangled with all the hairs, which affects the drainage performance. For this reason, an easy-to-clean multi-filter structure is developed to effectively reduce the fall of hair from the floor drain core and affect the drainage performance. Contents o...
