Novel deodorization floor drain core

Abstract

The invention discloses a novel deodorization floor drain core. The novel deodorization floor drain core comprises an upper cover plate, a filter net and a core tube, wherein the upper side of the upper cover plate is sleeved with the filter net, the core tube is arranged below the filter net, an upper thread is arranged at the upper end of the outer side of the core tube, the lower end of the outer side of the core tube is provided with a lower thread, the core tube is connected with the upper cover plate through the upper thread, a press angle is arranged on the periphery of the inner diameter of the upper end of the core tube, an upper filter core, an upper inner core tube, a lower filter core and a lower inner core tube are arranged on the lower side of the press angle in sequence, an inner press foot is arranged on the periphery of the inner diameter on the lower end of the upper inner core tube, an outer thread is arranged on the outer diameter of the lower end of the lower inner core tube, the upper filter core is jacked against the lower side of the press angle by the upper inner core tube, the lower filter core is jacked against the lower side of the inner press foot by the lower inner core tube, the lower inner core tube is connected with the core tube through the outer thread, supporting wings are arranged on the two sides of the upper filter core and the two sides of the lower filter core, and self closing water outlets are formed in the lower sides of the upper filter core and the lower filter core. The novel deodorization floor drain core has the advantages that the water-free sealing is achieved, the water draining speed is fast, the sealing effect is good, the service life is long, the maintenance cost is low, blocking is not prone to happen, and straight-through type water draining is achieved.

Description

technical field [0001] The invention relates to a floor drain, in particular to a waterless and odor-proof floor drain core. Background technique [0002] At present, most of the anti-odor floor drains on the market are water-sealed floor drains, flap floor drains, spring floor drains, and silicone floor drains. Water-sealed floor drains are easy to block and breed bacteria, and because the volatilization of water will affect the sealing effect of the floor drain, the flap floor drain Although the drainage speed is fast, the sealing effect is poor and it cannot deodorize. The spring of the spring floor drain is easily corroded by sewage and the increase in the number of uses leads to weakened elasticity and short service life. [0003] However, the filter element and the core barrel of traditional silicone floor drains are mostly integrated. After the filter element is damaged, it needs to be replaced as a whole, and the maintenance cost is high. In addition, the filter elem...

Problems solved by technology

[0002] At present, the deodorant floor drains on the market are mostly water-sealed floor drains, flap floor drains, spring floor drains, and silicone floor drains. Water-sealed floor drains are prone to blockage and bacteria breeding problems, and because the volatilization of water will affect the sealing effect of the floor drain, the flap floor drain Although the drainage speed is fast, the sealing effect is poor and it cannot deodorize. The spring of the spring floor drain is easily corroded by sewage and the increase in the number of uses leads to weakened elasticity and a short service life.

[0003] However, the filter element and cartridge of traditional silicone floor drains are mostly integrated. After the filter element is damaged, it needs to be replaced as a whole, and the maintenance cost is high. In addition, the filter element of traditional silicone floor drain is mostly a single-core structure, which is prone to seal failure due to lax closure of the drain outlet or foreign objects caught. , affect the deodorant effect
