Odor-resistant floor drain

Abstract

The invention discloses an odor-resistant floor drain. The odor-resistant floor drain comprises a floor drain main body (3), a central connecting pillar (18) and a lower sealing mechanism, wherein the central connecting pillar (18) is connected inside the floor drain main body (3), the upper end of the lower sealing mechanism is connected inside the central connecting pillar (18) in a sliding manner, and the lower end of the lower sealing mechanism and the lower end surface of the floor drain main body (3) form a lower valve port. The odor-resistant floor drain further comprises a flow guide base (6) with a flow guide structure on the upper end, and a swing blade sleeve (7) provided with at least one swing blade (8) on the upper end, wherein the flow guide base (6) is tightly matched in the floor drain main body (3), and sleeves the upper end of the swing blade sleeve (7), and the lower end of the swing blade sleeve (7) sleeves the central connecting pillar (18); and an outfall (9) forming an upper valve port (9) with the swing blades (8) of the swing blade sleeve (7) under the action of a locking mechanism is arranged on the flow guide base (6). After the structure is adopted, the floor drain has double valve blocking effects, and therefore, the odor-resisting effect is good.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a deodorant floor drain. Background technique [0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the house, its performance directly affects the quality of the indoor air. It is very important for the odor control in the bathroom. Now families choose to use deodorant The floor drain has eliminated the ordinary floor drain. At present, according to the principle of deodorization, deodorant floor drains can be divided into water seal deodorization, deodorization with cover and deodorization with floating ball. Water sealing and deodorization are the most traditional and most sensible. In the structure of the floor drain, the water storage bay is the key point. The floor drain mainly relies on the water tightness to prevent odors. However, it needs to design a water storag...

Problems solved by technology

But, the problem that this kind of floor drain exists is: because the sealing cover at the lower end of the floor drain realizes the sealing of the lower end face of the water seal body under the elastic force of the spring, and the spring is located on the central axis of the sealing cover, therefore, when the sealing cover is on When moving down under the action of water pressure, the cover plate of the sealing cover is prone to be inclined due to unbalanced force, so that when the sealing cover is reset and moved up under the action of the spring, the cover plate of the sealing cover cannot be in contact with the main body of the water seal. In addition, the spring is prone to fatigue after long-term use, which leads to the failure of the spring, so that the sealing effect of the sealing cover cannot be guaranteed; the above reasons will cause the loss of the anti-odor function of the floor drain
