7. The air ventilation and deodorization integrated device for toilet according to claim 1, characterized in that, The first springs (189) are sleeved on the outer walls of the insertion rods (188), and the number of the first springs (189) is four.

8. The method of using an air ventilation and deodorization integrated device for a toilet according to any one of claims 1 to 7, characterized in that, First, the connecting plate (20) on the second guide rail (193) is placed at the outer wall of the toilet, and then the connecting plate (20) is fixed in position by bolts (21); at this time, the first guide rail (182) on the shell (1) is placed inside the sliding groove (186) on the mounting frame (184), and the first guide rail (182) on the shell (1) is slid along the sliding groove (186) on the mounting frame (184); then the plug rod (188) is extruded by the arc-shaped leaf spring (183), so that the plug rod (188) moves along the guide hole (185) until it slides onto the support frame (1810); at this time, under the action of the first spring (189) on the moving plate (187), the plug rod (188) resets along the guide hole (185), and the plug rod (188) is inserted into the limiting groove (181), so that the shell (1) is fixed in position; at this time, pull the lifting disc (198), so that the adjusting rod (199) descends along the lifting hole (197) on the fixed plate (196), and the electromagnetic adsorption disc (1911) is adsorbed to the fixed plate (196), so that the U-shaped limiting plate (1910) is separated from the rotating handle (195); then twist the rotating handle (195) to rotate the lead screw (194); then under the action of the threaded hole (192), the sliding block (191) on the mounting frame (184) descends along the second guide rail (193), and the shell (1) descends to the specified position; at this time, the electromagnetic adsorption disc (1911) is turned off; at this time, under the action of the second spring (1912) on the lifting disc (198), the adjusting rod (199) resets along the lifting hole (197) on the fixed plate (196), and the U-shaped limiting plate (1910) is inserted into the outside of the rotating handle (195), so that the rotating handle (195) is positionally limited; when the equipment needs to run, there are two modes. In mode one, the controller (11) turns on the nano water ion sterilization and purification module (7), the air supply fan (12), and the first adjusting valve (14), and the odor in the toilet is deodorized and purified by the one-way flow internal circulation mode. The deodorization and purification process of the one-way flow internal circulation mode is as follows: the odor in the toilet passes through the return air inlet (3), is sterilized and deodorized by the nano water ion sterilization and purification module (7), enters the cavity (16) through the first adjusting valve (14) after deodorization and purification, and is sent into the toilet after passing through the air supply fan (12), the coarse filter screen (4), the medium filter screen (5), and the air supply inlet (2). When the infrared human body sensor (10) senses that there is a person in the toilet, the equipment changes from mode one to mode two, the controller (11) turns on the exhaust fan (13) and the second adjusting valve (15), and turns off the first adjusting valve (14). The odor in the toilet is deodorized by the fresh air replacement of the two-way flow external circulation mode. The ventilation and purification process of the two-way flow external circulation mode is as follows:The odor in the toilet is sterilized, deodorized and purified by the nano water ion sterilization and purification module (7) on the support frame (17) through the return air inlet (3), and then discharged to the outdoor through the total heat exchanger (6), the exhaust fan (13) and the exhaust air outlet (8). The outdoor fresh air enters the cavity (16) through the air inlet (9), the total heat exchanger (6) and the second adjusting valve (15), and then enters the toilet through the air supply fan (12), the coarse filter screen (4), the medium filter screen (5) and the air supply outlet (2), thereby completing the deodorization process.

9. The method of using an air ventilation and deodorization integrated device for a toilet according to claim 8, wherein In mode two, the outdoor fresh air and the toilet odor exchange heat through the total heat exchanger (6).

10. The method of claim 8, wherein the air ventilation and deodorization integrated apparatus for a toilet is used as a toilet seat. In mode two, when the infrared human body sensor (10) senses that there is no one in the toilet, the device is switched from mode two to mode one.
