Disclosure of Invention
The invention aims to provide a method for guaranteeing the sealing performance of a bottom valve of a cavity suction type vacuum transition tank, wherein the lower part of the vacuum transition tank is set to be of a reduced diameter structure, and the area of a drain outlet at the lower end of the vacuum transition tank is reduced through the reduced diameter structure, so that the weight of the bottom valve on the drain outlet is reduced, and the vacuumizing adsorption force of a vacuum generating device can enable the bottom valve to cover the drain outlet tightly so as to guarantee the sealing performance of the bottom valve of the vacuum transition tank.
In order to achieve the above purpose, the present invention proposes the following technical scheme: the vacuum transition tank is of a cavity suction type structure, the lower part of the vacuum transition tank is set to be of a reduced diameter type structure, a drain outlet and a bottom valve matched with the area of the drain outlet are arranged at the lower end of the reduced diameter type structure, the area of the drain outlet is reduced through the reduced diameter type structure, and then the weight of the bottom valve is reduced, so that the vacuum suction adsorption force of the vacuum generating device enables the bottom valve to cover the drain outlet tightly so as to ensure the sealing performance of the bottom valve of the vacuum transition tank.
The technical effects are as follows: in the scheme, when the vacuum generating device works, the vacuum adsorption force can adsorb the bottom valve upwards to enable the bottom valve to cover the sewage outlet tightly; if the weight of the bottom valve is large, the vacuum adsorption force cannot adsorb the bottom valve upwards, so that the bottom valve cannot be tightly covered; or when the bottom valve cover is tightly closed, the adsorption force of the vacuum generating device can not enable the bottom valve to be tightly closed on the sewage outlet, so that a gap is formed between the bottom valve and the sewage outlet; thereby influencing the sealing performance of the vacuum transition tank and preventing the vacuum negative pressure from being formed in the vacuum transition tank.
Preferably, the vacuum transition tank is provided in a combined structure comprising an upper cavity and a lower cavity, and the diameter-reduced structure is provided at the lower part of the lower cavity. The vacuum transition tank of the combined structure reduces the processing difficulty, the upper cavity and the lower cavity are more convenient for demolding compared with the integral structure, meanwhile, the combined structure is also convenient for overhauling parts and replacing parts, and compared with the integral vacuum transition tank, the vacuum transition tank is more universal.
Preferably, the diameter-reducing type structure is a diameter-reducing type conical barrel, the inner diameter of the conical barrel is gradually reduced from top to bottom, a drain outlet is formed at the lower end of the conical barrel, a bottom valve is movably arranged on the drain outlet, and the weight and the angle of the bottom valve are matched with the vacuum suction force of the vacuum generating device. The internal diameter of the cone-shaped barrel gradually reduces from top to bottom, so the internal diameter of the lower end of the cone-shaped barrel is smaller, the internal diameter of the sewage outlet of the lower end of the cone-shaped barrel is smaller, the weight of the bottom valve matched with the cone-shaped barrel is smaller, and the bottom valve can be adsorbed and covered on the sewage outlet, so that the tightness of the vacuum transition tank is ensured.
Preferably, the included angle beta between the extension line of the inclined wall of the conical barrel and the axial center line L of the vacuum transition tank is set as follows: beta is more than or equal to 30 degrees and less than or equal to 60 degrees. When the included angle β is too large, for example, larger than 60 °, dirt cannot smoothly flow downwards to cause dirt to hang up and block on the inclined wall 17, and when the included angle β is too small, for example, smaller than 30 °, the length of the conical barrel is too long to occupy too large space in the dirt box, so that the dirt containing capacity of the dirt box is reduced.
Preferably, the drain outlet is set to be an inclined drain outlet, and an included angle alpha between the drain outlet and the bottom valve is set to be alpha less than or equal to 45 degrees when the vacuum generating device does not work, so that the bottom valve can be adsorbed upwards and the drain outlet is covered when the vacuum generating device begins to work. Namely, when the vacuum generating device does not work, the included angle alpha is less than or equal to 45 degrees under the condition that the bottom valve is normally opened, so that the bottom valve can be adsorbed upwards and the drain outlet can be covered when the vacuum generating device starts to work. If the included angle is too large, if the included angle is larger than 45 degrees, the adsorption force of the vacuum generating device cannot adsorb the bottom valve upwards, so that the bottom valve cannot tightly close the sewage outlet, a closed space cannot be formed in the vacuum transition tank, and negative pressure cannot be formed.
Preferably, the inner diameter of the sewage outlet is set to be larger than the inner diameter of the sewage inlet communicated with the upper part of the vacuum transition tank, so that the sewage outlet is prevented from being blocked by sewage.
Preferably, the volume of the vacuum transition tank is set to be 1.5-3 times of the full water volume of the toilet. The vacuum transition tank can be ensured to contain dirt sucked in the excrement discharging device, and the vacuum transition tank is prevented from being blocked.
Preferably, an air return device communicated with the vacuum generating device is arranged outside the vacuum transition tank, and an air outlet of an air return pipe in the air return device is aligned to the outer end face of the bottom valve; when the vacuum generating device works, odor in the vacuum transition tank flows back and blows to the bottom valve through the air outlet of the air return pipe, and then the bottom valve is assisted to be tightly closed on the sewage outlet, so that the vacuum transition tank is kept in a closed state.
Preferably, an access platform comprising an access door is arranged on the upper end surface of the vacuum transition tank, and a first sealing element is arranged on the inner wall of the access door. The access port is used for checking and overhauling the inside of the vacuum transition tank by workers, and the first sealing piece is further arranged on the inner wall of the access port, so that the tightness of the vacuum transition tank can be further enhanced.
Preferably, the lower end of the upper cavity extends outwards to form a convex edge I, the upper end of the lower cavity extends outwards to form a convex edge II, and the upper cavity and the lower cavity are connected through a plurality of fasteners arranged on the convex edge I and the convex edge II.

The toilet bowl 29 starts flushing, at this time, the vacuum generating device is started and adsorbs the movable bottom valve 6 upwards, vacuum negative pressure is formed in the vacuum transition tank and dirt is sucked into the dirt inlet area 8a from the toilet bowl 29 through the blow-down pipe, the dirt is flushed to the second side 12 of the baffle plate 11 in the dirt inlet area 8a and forms a vortex, solids, liquid and gas are separated up and down in the vacuum transition tank through the vortex, the dirt in the form of solids and liquid moves downwards and falls into the dirt box 22 from the conical barrel 16 and the blow-down port 5, and the odor in the vacuum transition tank moves upwards and is sucked from the air return pipe 24 through the vacuum generating device 21 and is discharged from the air outlet of the air return pipe 24 and blown to the movable bottom valve 6, so that the movable bottom valve 6 is assisted to tightly close the blow-down port 5. When the dirt is sucked up, the vacuum generating device is closed, the movable bottom valve 6 is opened downwards under the gravity of the dirt and the gravity of the movable bottom valve 6 itself, and the dirt falls into the dirt box 22.
The above examples are intended to be illustrative of the invention and not limiting, and those skilled in the art, after reading the present specification, may make modifications to the embodiments of the invention as necessary without inventive contribution, but are protected by the patent laws within the scope of the appended claims.
