Water seal type floor drain

Abstract

The invention relates to a water seal type floor drain, which comprises a filtering cover, a water seal, a water drainage opening and a semispherical floating body, wherein the semispherical floating body is arranged on the water drainage opening; a guide pipe is arranged in the center position of the floating body; a guide rod passes through the guide pipe and is in clearance fit with the guide pipe; the upper end of the guide rod is fixed on the filtering cover or the water seal; the floating body can vertically move along the guide rod through the guide pipe; the lower end of the guide pipe is in a horn opening shape; the lower end of the guide rod is provided with a cone body matched with the shape of the horn opening formed in the lower end of the guide pipe; the cone surface of the cone body is matched with the horn opening formed in the lower end of the guide pipe in a sealed way. The floor drain has the advantages that excessive gas accumulated between the floating body and the water seal can be released into a drain pipe through a gap formed between the guide pipe and the guide rod; the upwards floating pressure of the floating body can be effectively reduced; the free upward floating of the floating body can be ensured under the continuous mass water drainage condition of the floor drain; the water discharge is smooth; in addition, the stable vertical movement of the floating body can be realized; the deviation from the water drainage opening cannot occur.

Description

technical field [0001] The invention relates to a floor drain, in particular to a water-sealed floor drain. Background technique [0002] The traditional water-sealed floor drain (commonly known as the anti-odor floor drain) mainly includes the main body of the floor drain, the filter cover on the main body of the floor drain, the outlet of the downpipe and the water seal. The "U"-shaped backwater bend (or water trap) is sealed by using the water in the backwater bend to prevent the rise of sewer odor. Most water-sealed floor drains have shallow water seals and too little sealing water. Due to factors such as time and dry weather, the water in the return water bend will dry up and return to odor. In order to overcome the defects of the traditional water-sealed floor drain, the applicant once invented a water-sealed floor drain with a new structure, and obtained the patent right for the invention. The name of the invention is deodorant floor drain, and the patent number is 2...

AI Technical Summary

Problems solved by technology

However, there are also the following problems in actual use: 1. When the floor drain encounters a large amount of drainage and continues to discharge a large amount of water, the floating body continues to float, the space between the floating body and the water seal is further reduced, the air is compressed, and the pressure of the air on the floating body increases. Affect the floating body to float further, resulting in poor drainage

2. Since the floating body is placed on the water outlet without a stabilizing mechanism, the floating body will not float up and down smoothly under the action of the water flow, and may even deviate from the water outlet, which will affect the anti-odor effect
