Specifically, aiming at different working conditions, the working principle is as follows:

1. working condition that no water is flushed in deodorization process when user goes to toilet

Namely, the user does not open the flushing water at the same time in the whole process of opening the deodorization. At this time, the working water level of the water tank 10 is maintained at the full water inlet position, the deodorization chamber 40 of the deodorization and noise reduction device is partially immersed in water (the air section 48 is located above the water level), the switch valve 50 floats upwards under the combined action of buoyancy and gravity of the bottom cavity, the switch valve 50 opens the water inlet 49a on the buckle cover 49, water can pass through the water tank 52 from the side of the switch valve 50 and enter the water cavity of the deodorization chamber 40, and the deodorization chamber 40 meets the working environment of water deodorization, which is shown in fig. 12.

When a user presses the key 62, the switch on the circuit board 63 acts to control the fan 30 to work, odor enters the belly water channel of the toilet through the washing ring hole in the toilet under the action of pressure difference, then enters the deodorizing and noise reducing device through the overflow pipe 12 to be deodorized, and finally deodorized gas is discharged.

2. Working condition that users flush water simultaneously in deodorization process during toilet

That is, the flushing function is simultaneously started in the deodorization working process, including the case that the user starts the deodorization function first, presses the flushing condition or presses the flushing first in the deodorization working process, and the water in the water tank 10 is not filled to the working water level and the deodorization function is immediately started. During the water discharging and flushing, the water level of the water tank 10 is rapidly reduced from the highest water level to the lowest water level (in the process, water replenishing is usually started in time, but water replenishing is usually slower than water discharging, and the water level of the water tank is restored to the highest position again after a certain water replenishing time is needed), and the working water level line of the water tank is maintained at the position of the low water level after water discharging.

In the process of water level descending, the deodorization chamber 40 of the deodorization and noise reduction device is exposed out of the water, the switch valve 50 descends under the combined action of the water in the upper water storage tank 54 and the self gravity, the sealing surface 51 of the switch valve 50 closes the water inlet 49a of the buckle cover 49, the water is sealed in the water cavity of the deodorization chamber 40 and cannot leak, and the deodorization working environment of the water in the deodorization chamber 40 is also satisfied, as shown in fig. 14.

After the user presses the button 62, the switch action on the circuit board 63 controls the fan 30 to work, the odor enters the belly water channel of the toilet through the washing ring hole in the toilet under the action of pressure difference, then enters the deodorizing and noise reducing device through the overflow pipe 12 for deodorization, and finally the deodorized gas is discharged.

3. Overflow condition of water tank

Referring to fig. 12, when the toilet is normally sealed and deodorized, the working water level of the toilet body is at a normal position, the float 27 is not subjected to buoyancy in the air, and the sealing gasket on the float 27 is contacted with the ribs on the bracket 26 to form a sealed space under the action of self weight; referring to fig. 13, when the water level of the water tank 10 rises abnormally, the water level line exceeds the normal working height position of the toilet bowl, reaches the position of the float 27, the float 27 is under the action of buoyancy, the sealing gasket on the float is separated from the rib on the bracket 26, the drain hole 28 is opened, and the overflow water enters the overflow pipe 12 through the drain hole 28, so that the overflow protection function is realized.
