Problems solved by technology

[0002] The most commonly used toilet is now generally equipped with a water storage tank, which stores 10 to 15 kilograms of water, and an "S"-shaped sewer pipe is installed at the lower end of the toilet pool, using the principle of "S" curved water seal. It is very large, and it is a great waste for a country such as my country, which is very scarce in water resources. Therefore, a tankless toilet has emerged at the historic moment, and its water-saving effect is better. The double trap disclosed in Chinese patent 02116299.9 Toilet patent, its structure is more complex, using tap water and hydraulic cylinder as negative pressure generating device, applying the negative pressure generated by the hydraulic cylinder between the two water traps, using less clean water to replace the bedpan trap The mixed liquid inside is used to achieve the purpose of rinsing clean and saving water. The space between the double traps is large, and the water pressure cylinder and the pumping cylinder are one cylinder, which will greatly affect the effect of negative pressure pumping. When flushing The flow rate of the water will be greatly affected, resulting in poor flushing effect

Embodiment 1

[0021] Embodiment one: refer to figure 1 and Figure 4 , the negative pressure generating driving device is arranged at the opening 45 of the sewage pipe 2 above the water trap 3, the negative pressure generating driving device includes a pumping cylinder 21, the side and bottom of the pumping cylinder 21 communicate with the opening 45 of the sewage pipe 2, and the pumping The cylinder 21 is provided with a gravity column 22 that can communicate with and block the sewage pipe 2, and the upper side wall of the pumping cylinder 21 is provided with a return pipe 80 and a number of exhaust holes 55 that communicate with the sewage pipe 2. The accumulated water in the pumping cylinder 21 above 22 is discharged into the sewage pipe 2, the lower end of the gravity column 22 is provided with a sealing ring 29 that seals the water trap 3, and the top of the pumping cylinder 21 is provided with a hydraulic cylinder 24. The cylinder 24 includes a bottom flange 23 and an internal piston...

Embodiment 2

[0024] Embodiment two: refer to figure 2, and the difference from Embodiment 1 is that the gravity column 22 of the negative pressure generation drive device draws negative pressure on the closed space in the sewage pipe 2 at the bottom of the trap 3 through the pipeline 30, and a single unit is provided at the lower port of the sewage pipe 2. to valve 50. This embodiment is applicable to the toilet with the water trap 3 arranged on the upper part of the sewage pipe 2, and the lower port of the sewage pipe 2 must be provided with a one-way valve 50, otherwise the negative pressure cannot be drawn, and the water return port 15 on the water valve 6 passes through the pipeline. Connect to the top of the lower outlet of the sewage pipe 2, and flush the seal of the one-way valve 50.

Embodiment 3

[0025] Embodiment three: refer to image 3 , is different from Embodiment 1: the rear end of the pedal 7 is provided with a lever 9 hinged by a bracket 8, and the lever 9 is connected to the top of the gravity column 22 through the fixed pulley 33 and the fixed pulley 34 through the wire rope 32, and the negative pressure generates the drive The negative pressure power of the device comes from the lever force. By stepping on the pedal 7, the lever 9 is driven, and the lever 9 drives the gravity column 22 to rise to perform negative pressure on the space above the water trap 3. At the same time, the water delivery port 14 of the water valve 6 and the The water delivery pipe 4 is directly connected, and the bedpan 1 is flushed through the water flushing pipe 5 . This embodiment does not need to use components such as the hydraulic cylinder and the piston described in the first embodiment.
