Toilet bowl with low water tank

Abstract

The invention discloses a toilet with a low water tank, which comprises a toilet body, the toilet body is provided with a urinal and a sewage discharge channel communicated with the bottom of the urinal, a first trap is formed at an inlet of the sewage discharge channel to form a first water seal, and a second trap positioned at the downstream of the first trap is further arranged on the sewage discharge channel to form a second water seal; a water-sealed first cavity is formed in the space, between the first trap and the second trap, of the sewage discharge channel; the water tank is positioned behind the urinal; the piston type mechanism comprises a piston cylinder and a piston, the piston divides an inner cavity of the piston cylinder into a second cavity and a third cavity in a sealed mode, and the third cavity is communicated with the outside; the first end of the air passing pipe is communicated with the first cavity, and the second end of the air passing pipe is communicated with the second cavity; the piston type mechanism drives the piston to move in the direction of compressing the third cavity so as to enable the second cavity to generate negative pressure, and then gas in the first cavity is sucked through the gas passing pipe so as to promote siphon of the drainage channel.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a toilet with a low water tank. Background technique [0002] Due to the low tank toilet (such as the flat toilet on the market, the top surface of the water tank is not higher than the top surface of the urinal or the top surface of the water tank is only slightly higher than the top surface of the urinal) is more concise in appearance Beautiful, so more and more consumers of all ages. However, due to the low position of the water tank, the gravitational potential energy of water alone is not enough to effectively flush the toilet. Some existing low-tank toilets use the water pressure of tap water to assist flushing, and some low-tank toilets use water pumps to suction the water tank. Water is assisted by negative pressure flushing, etc. Both of these methods increase the flushing capacity by increasing the flushing force value of the flushing water, and the effect of im...

Problems solved by technology

These two methods improve the flushing capacity by increasing the flushing force value of the flushing water, and the effect of improving the flushing capacity still needs to be further improved
