Description

TECHNICAL FIELD

The present invention relates to a deodorization apparatus with a smart cover plate.

BACKGROUND

Regarding a main prior method for deodorization of lavatories, deodorization is achieved by using toilet cleaner and incense, which is troublesome for users and does not radically solve the problem of odor. Moreover, in a small number of toilets, activated carbon is used to deodorize. However, since the lavatory is a singularly moist area, the activated carbon has a decreased adsorption effect after being exposed to moisture, resulting in a shortened service life. Thus, the filtering materials need to be replaced frequently to achieve an excellent deodorization effect, which is inconvenient for users to use and has a poor deodorization effect.
A patent document WO 2019/042328 A1 discloses a deodorization device for a toilet, comprising an exhaust fan and a heating module. The exhaust fan is used for sucking odor of the toilet, and the heating module is provided in a water tank and used for heating water. The exhaust fan is used for sucking the odor out and mixing the odor with water, indole in the odor is dissolved into hot water to form cleaned air, the hot water in which indole is dissolved flows back to the water tank, and is discharged into a sewer when the toilet is flushed.
A second patent document CN 108 343 134 A discloses a toilet purifying and deodorizing device, including a fan, an atomizer and a filtering member set between the atomizer and the outlet of the fan, said fan is used to draw odor from the commode, said atomizer is used to produce water mist, said water mist will wet the filtering member, when the odor gas drawn by the fan passes through the wetted filtering member, the odor molecules in the odor gas are reproduced and dissolved in the water mist.
A third patent document CN 207 244 758 U discloses a deodorizing toilet, comprising the main body of the toilet, a water tank and a deodorizing system, wherein the main body of the toilet is connected to the water tank through a pipe, said deodorizing device is set inside the tank, said deodorizing device includes a water filtration deodorizing system, a catalytic deodorizing system and an ozone sterilizing system, the gas of the main body of the toilet seat enters the deodorizing system for deodorizing through the pipe connected to the water tank, specifically, the water filtration deodorizing system dissolves the dissolvable substances in the gas in the water, and then the ozone sterilization system kills the bacteria and viruses in the gas through the ozone generated by the ozone generator, while also oxidizing and reducing the harmful and toxic substances in the gas.
A fourth patent document CN 108 442 482 A discloses a cesspit deodorizing device. The cesspit deodorizing device is used for deodorization of cesspit-type squatting toilets. The device includes a suction fan and a blower; the suction fan is used for sucking air from a cesspit, the blower is used for blowing air into the cesspit, the suction fan is connected with an air suction pipeline, the air suction pipeline forms an air suction port facing the cesspit, the blower is connected to an air blowing pipeline, the air blowing pipeline forms an air blowing port facing the cesspit, the air suction port and the air blowing port are positioned in the two opposite sides of the cesspit respectively, correspondingly directional airflow flowing from the air blowing port to the air suction port is formed in the cesspit.
A fifth patent document US 6 823 532 B1 discloses a malodor control system for a toilet comprises a modified toilet seat which is a hollow construction. The seat may be mounted on supports for pivotal movement between an up position and down position in which its opening is registered with the opening of an toilet bowl for receiving products of human waste. As in conventional toilets, portions of a person sitting on the seat define a chamber, in combination with the seat and the bowl. A pair of water spray nozzles are disposed within the hollow seat and directed rearwardly toward the pivotal mounting for the seat. A water supply system includes a flexible tube connection between a fixed source of pressurized water and a bracket for pivotally mounting the seat. Flow of water to the spray nozzles is controlled by a valve on the rear of the seat. The water spray induces flow of fouled air from the user defined chamber into the hollow seat where offensive odors are removed by the water spray. Entrainment separators, downstream of the spray nozzles, precipitate water from the air. The water is then returned to the toilet bowl, while the cleansed air is discharged from the seat. An air freshener unit, downstream of the entrainment separator further additionally treats the air to make it more pleasant.
A sixth patent document CN 110 594 884 A discloses a quiet air purification device, including a shell, and a purification module set inside the shell, said shell is formed with an air inlet and an air outlet, said purification module includes a fan, said fan from the air inlet to pump the external air to be purified into the shell, the air is purified by the purification module and discharged from the air outlet, said purification module and the air inlet is formed with an air inlet duct, and the air outlet is formed with a muffler between at least one of the air inlet duct and the air outlet duct.

4. An oblique meshy drip plate is further provided in the reaction cavity, and the meshy drip plate is provided with a plurality of mesh holes. When the water of the water outlet holes flows through the meshy drip plate, a water film can be formed on the mesh holes, and the water film can further increase the contact area with the odor and improve the deodorization effect.
5. A water outlet end of the water inlet channel is fixedly provided with a core, and the core is provided with a plurality of oblique water channels at intervals. When the water enters, a water flow rotates under the action of the oblique water channels to produce a centrifugal force, and the water is dispersed and then sprayed into the reaction cavity.
