[0026] By setting the ventilation box 2 and the exhaust device 3, when it is necessary to discharge the air in the sanitary unit body 1, first open the exhaust device 3 to allow the air to enter the exhaust device 3 through the through hole 14 and be discharged. At the same time, open the ventilation box 2, and after the outside air enters the ventilation box 2, it is discharged through the ventilation pipe 4 connected to the air outlet end, passes through the three-way valve 41 and the connecting pipe 42, and flows into the ventilation pipe 43, and finally is discharged into the sanitary unit body 1 through the vent 13 on the connecting plate 12. By opening the ventilation box 2 to discharge the outside air into the sanitary unit body 1, the gas circulation in the sanitary unit body 1 is accelerated, and the ventilation speed of the sanitary unit body 1 is accelerated. At the same time, with the setting of multiple ventilation slots 11 and the three-way valve 41, the user can choose to open one or two valves for ventilation according to actual needs.

[0027] For example 2, please refer to Figure 1 and Figure 4 A first suction pump 21 is fixedly installed inside the ventilation box 2, a second filter screen 25 is fixedly connected to the air inlet end of the ventilation box 2, and a gauze is provided at the front end of the second filter screen 25. A first filter plate 22 is also fixedly installed in the ventilation box 2, a second filter plate 23 is fixedly installed on the other side of the first filter plate 22, and an air freshener 24 is fixedly installed on the other side of the second filter plate 23. The air outlet end of the ventilation box 2 is connected to the ventilation pipe 4;

[0028] When ventilating the sanitary unit body 1 through the ventilation box 2, first turn on the first suction pump 21 to allow the outside air to enter the ventilation box 2 through the second filter 25. When the air passes through the second filter 25, the gauze at the front end of the second filter 25 will perform a preliminary filtration of impurities in the air to prevent larger foreign objects from entering the ventilation box 2 and causing blockage. After the air enters the ventilation box 2, it passes through the double filtration of the first filter plate 22 and the second filter plate 23. When the air is discharged from the second filter plate 23, it passes over the top of the air freshener 24 and is mixed with the gas emitted by the air freshener 24. It enters the sanitary unit body 1 through the ventilation pipe 4. Through multiple filtration in the ventilation box 2, the gas entering the sanitary unit body 1 is purer. Through the setting of the air freshener 24, the gas is made fresher. After the gas enters the sanitary unit body 1, the odor in the sanitary unit body 1 can be covered, and the interior of the sanitary unit body 1 is preliminarily deodorized.

[0029] For example three, please refer to Figure 1 、 Figure 2 and Figure 3 , a first filter 15 is provided on the through hole 14, and a plurality of exhaust holes 16 distributed circumferentially are provided on the first filter 15, and the air outlet end of the first filter 15 is connected to the exhaust pipe 17, the exhaust device 3 includes an exhaust box 31, one side of the exhaust box 31 is fixedly connected to the side wall of the sanitary unit body 1, and a second suction pump 36 is fixedly installed on the side of the exhaust device 3 close to the sanitary unit body 1, and the air outlet end of the second suction pump 36 is communicated with the interior of the exhaust device 3, and the air inlet end of the second suction pump 36 is communicated with the exhaust pipe 17, an activated carbon plate 32 and a third filter plate 33 are fixedly installed in the exhaust box 31, and a water collecting tank 34 is provided on the side of the activated carbon plate 32 close to the sanitary unit body 1, and a plurality of parallel exhaust ports 35 are provided on the surface of the exhaust box 31 away from the sanitary unit body 1, and an openable baffle 37 is provided on one side of the exhaust box 31, and a handle 38 is fixedly installed on the bottom end of the baffle 37;

[0030] By setting the exhaust device 3, the second suction pump 36 is first turned on when exhausting, and the air in the sanitary unit body 1 passes through the exhaust hole 16 opened on the first filter 15 into the exhaust pipe 17 through the suction of the second suction pump 36, and is discharged into the exhaust box 31 through the exhaust pipe 17. When the gas enters the exhaust box 31, the odor in the gas is adsorbed and filtered by the activated carbon plate 32 and the third filter plate 33. When the water content of the gas is large, the gas will adhere to the surface of the activated carbon plate 32 when it contacts the activated carbon plate 32, and flow down along the surface of the activated carbon plate 32 to the water collection tank 34 for collection. By setting the activated carbon plate 32 and the third filter plate 33, the sanitary unit The air containing odor in the element body 1 is purified to prevent the air containing odor from being directly discharged to pollute the outside air and reduce the quality of life on the ship. At the same time, by setting a water collection tank 34, water droplets can be collected in the water collection tank 34 to prevent water vapor from accumulating in the exhaust box 31 and affecting the filtering and adsorption effects of the activated carbon plate 32 and the third filter plate 33. After the air is filtered by the activated carbon plate 32 and the third filter plate 33, it is discharged through the exhaust port 35. When the water collection tank 34 is full, the baffle 37 is opened by pulling the handle 38, the water collection tank 34 is taken out, the accumulated water in the water collection tank 34 is cleaned and put back in place. At the same time, the activated carbon plate 37 can be replaced conveniently and regularly.

[0031] For example 4, please refer to Figure 3 、 Figure 5 and Figure 6 The exhaust pipe 17 and the plurality of vent pipes 43 are both fixedly installed with a check valve 5, and the check valve 5 includes a fixed plate 51, which is fixedly connected to the inner wall of the check valve 5, and a rotating shaft is fixedly installed on the fixed plate 51. The fixed plate 51 is rotatably connected to a limiting plate 52 via the rotating shaft, and the limiting plate 52 abuts against the inner wall of the check valve 5;

[0032] By installing a check valve 5 in the exhaust pipe 17, when the exhaust device 3 is started and the exhaust operation is performed, the gas enters the exhaust pipe 17 through the suction of the second suction pump 36, blows up the restriction plate 52 in the exhaust pipe 17, lifts the restriction plate 52, and the gas enters the exhaust box 31 through the gap between the inside of the check valve 5 and the restriction plate 52. When the second suction pump 36 is turned off, no gas enters the exhaust pipe 17, and the restriction plate 52 is reset by the rotating shaft to maintain contact with the check valve 5. By arranging the check valve 5 on the exhaust pipe 17, the gas in the exhaust box 31 can be prevented from flowing back into the sanitary unit body 1, and the newly injected air in the sanitary unit body 1 can be kept clean at all times. By arranging the check valve 5 on the ventilation pipe 43, the air containing odor can be prevented from entering the ventilation box 2 through the vent 13 and mixing with the clean air in the ventilation box 2 when the second suction pump 36 is exhausted.

[0033] The working principle of the present utility model is as follows: when it is necessary to discharge the gas in the sanitary unit body 1, first start the second suction pump 36 to allow air to enter the exhaust pipe 17 through the exhaust hole 16, and the restriction plate 52 in the exhaust pipe 17 is blown up, so that the air enters the exhaust box 31, and the odor in the air is adsorbed by the activated carbon plate 32, and then filtered by the third filter plate 33, and then discharged through the exhaust port 35. When air with a large amount of water vapor enters the exhaust box 31, the water vapor adheres to the surface of the activated carbon plate 32 and flows along the activated carbon plate 32 into the water collection tank 34 for collection. When the water collection tank 34 is full, open the baffle 37 to take out the water collection tank 34 for cleaning, and put it back in place after cleaning. At the same time, it is convenient to replace the activated carbon plate 37 regularly. When the exhaust device 3 is exhausting, turn on the first suction pump 2 1, so that the outside air passes through the second filter 25 into the ventilation box 2, through the preliminary filtration of the second filter 25 and the double filtration of the first filter plate 22 and the second filter plate 23, the filtered gas is discharged into the sanitary unit body 1 through the ventilation pipe 4, when the gas passes above the air freshener 24, and the odor emitted by the air freshener 24 is mixed, when the mixed gas enters the sanitary unit body 1, the gas containing odor in the sanitary unit body 1 is covered, and the sanitary unit body 1 is preliminarily deodorized. At the same time, when a stronger ventilation effect is required, the two valves can be opened so that each ventilation pipe 43 can be ventilated. When a too strong ventilation effect is not required, one valve can be opened to ventilate one or two ventilation pipes 43. The user can adjust according to actual needs.
