Direct-flushing water-saving toilet seat

Abstract

A straight-flushing water-saving closetool comprises a closestool body and a water tank. A water feeding control component and a water draining valve are arranged inside the water tank. The closestool is characterized in that the closestool body can be divided into a stool-receiving cavity and an isolating cavity; a sewage draining outlet is respectively arranged on the lower parts of the stool-receiving cavity and the isolating cavity; a sealing support plate is articulated inside the isolating cavity; the front part of the sealing support plate appears as a disc shape which blocks the closetool draining outlet at the lower end of the stool-receiving cavity; a weight-balancing part is arranged at the rear part of the sealing support plate; a rotary shaft, one end of which is threaded through the water tank, is arranged on the upper part of the water tank; the lead-out end of the rotary shaft is provided with a handle; the front part of the rotary shaft is connected by a link rod with a piston rod of a draining valve; and the rear part of the rotary shaft is connected with the rear end of the sealing support-plate by the link rod and a pulling rope. The closestool has the advantages that the structure is simple; the use is convenient; the straight-flushing is realized and the water-using quantity is low and the water saving capability is good; the flushing effect is clean and complete; after the flushing is completed, the disc mouth at the front part of the sealing support plate can contain a little clean water to realize the water sealing with good sealing effect so as to avoid the air pollution and be beneficial to body health.

Description

technical field

[0001] The invention particularly relates to a flush-down water-saving toilet seat. Background technique

[0002] Traditional toilets often adopt a siphon backwater bend structure to achieve sealing. The toilet with this structure consumes a lot of water, and the backwater bend is easy to be blocked after a long time of use, so it has been gradually eliminated by the market. The Chinese patent with the publication number CN2528811Y discloses a flush valve type water-saving toilet. The toilet has canceled the return water bend, and a drain valve is set at the sewage outlet at the bottom of the toilet. The drain valve is connected to the water tank through a connecting rod mechanism. Although the water consumption is reduced after the backwater bend is removed, the sealing effect of the drain valve is poor, and the odor in the sewer is easy to come out from the sewage outlet, polluting the air in the bathroom. The Chinese patent with publication number CN24251...
