detailed description

The embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings by taking the ventilation valve constituted by a solenoid valve as an example.

Please refer to the above accompanying drawings, the present invention discloses a vacuum toilet with a ventilation valve (92) in a vacuum toilet (01) equipped with a flushing nozzle (03), an on-off valve (100), and a sewage pipe (07). (01) vacuum type ventilator (90),

The above-mentioned vacuum type ventilation device (90) is equipped with a ventilation pipeline (91) between the above-mentioned flushing nozzle (03) and the water supply valve (06);

The equipped ventilation line (91) is connected between the vacuum port (72) of the connecting pipe (70) and the check valve (62), and the connecting pipe (70) is connected to the sewage pipe (07);

A ventilation valve (92) and a vacuum pressure switch (93) such as a manual valve, a solenoid valve or a pneumatic valve are equipped in the middle of the above-mentioned ventilation pipeline (91);

After the ventilation valve (92) is opened, the vacuum pressure through the sewage pipe (07) drives the stench of the above-mentioned vacuum toilet (01) to be discharged into the above-mentioned sewage pipe (7) through the above-mentioned flushing nozzle (03) and the ventilation valve (92). .

Moreover, when the vacuum degree of the above-mentioned sewage pipe (07) drops to an excessively low value below the preset value, the above-mentioned vacuum pressure switch (93) will take action to cover the above-mentioned ventilation valve (92) to prevent the sewage pipe (07) from Vacuum drops to too low a value below the preset value.

The above content will be further explained below.

First, according to the present invention, the vacuum type ventilation device (90) mainly includes: a vacuum toilet (01), an on-off valve ( 100), the connecting pipe (70) connecting the above-mentioned on-off valve (100) and the sewage pipe (07), the flushing nozzle (03) assembled in the above-mentioned vacuum toilet, and the water supply valve ( 06), vacuum pipeline (60), check valve (62), control valve (66), connect vacuum port (72) and check valve (62) between the above-mentioned flushing nozzle (03) and water supply valve (06). ), the air exchange valve (92) and the vacuum pressure switch (93) in the middle of the air exchange line (91), the controller (08) of the control device action.

The above-mentioned vacuum toilet (01) sprays water from multiple flushing nozzles (03) on the inner side to flush the excrement and urine and discharges it to the sewage pipe (07) through the on-off valve (100) connected to the lower discharge port (02). At this time, the water supply line (04) provided with the water supply valve (06) is connected to the above-mentioned flushing nozzle (03).

According to the present invention, the main components of the vacuum ventilation device (90) mainly include: a ventilation pipeline (91), connecting the vacuum port (72) and the stop valve between the above-mentioned flushing nozzle (03) and the water supply valve (06). The return valve (62) is connected; the air exchange valve (92) and the vacuum pressure switch (93) are prepared in the middle of the air exchange pipeline (91); the controller (08) is used for controlling the action of the device.

When the user activates the action switch (8-1) of the controller (08) during the defecation process, the ventilation valve (92) of the above-mentioned ventilation pipeline (91) will be opened to allow the stench of the vacuum toilet to pass through the above-mentioned sewage pipe ( The vacuum pressure of 07) is discharged to the sewage pipe (07) through the above-mentioned flushing nozzle (03) and ventilation valve (92), preventing bad odor from being discharged from the toilet to the outside and maintaining a comfortable toilet.

When the above-mentioned ventilation valve (92) is opened and the stench is discharged into the sewage pipe (07), the vacuum pressure of the sewage pipe is maintained at a certain value by the vacuum pump shown in Figure 1. When the vacuum degree of the sewage piping (07) is excessively reduced by opening the ventilation valve (92) for ventilation, the vacuum pressure switch (93) will operate to cover the ventilation valve (92), thereby preventing the sewage piping ( 07) The vacuum degree drops to a too low value below the preset value.

Moreover, the ventilation valve (92) and the water supply valve (06) are opened and closed alternately. When the above-mentioned ventilation valve (92) is opened, the above-mentioned water supply valve (06) must be closed, and when the above-mentioned water supply valve (06) is opened, the above-mentioned The gas exchange valve (92) must be closed. That is, it is not allowed to open the above-mentioned ventilation valve (92) and water supply valve (06) simultaneously.

Above-mentioned air exchange valve (92) can use valves such as manual valve, electromagnetic valve or pneumatic valve, but the electromagnetic valve that can operate in electrical mode is better, and the built-in timer in controller (08) avoids air exchange valve ( 92) is better if the opening time is too long.

Moreover, for the sake of flexibility during installation, it is better to use a hose made of rubber for the ventilation line (91).

【Industrial use】

The present invention can be used in a vacuum toilet system to remove bad odors occurring in the toilet.
