[0026] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention can be defined and covered by a variety of different implementations according to the claims.

[0027] like Figures 1 to 9 The oxygen-enhancing disinfection machine shown includes a housing 1 having a receiving space 1A, and an ozone preparation device 3 and an air outlet device 5 arranged in the housing 1. Among them, since ozone is easily decomposed into oxygen at room temperature, the ozone provided by the ozone preparation device 3 usually exists as a mixed gas of ozone and oxygen, and the air outlet device 5 can realize two working modes, one mode is to directly emit ozone gas to disinfect the surrounding environment; the other mode is to emit gas after the ozone gas is decomposed into oxygen, which can increase the oxygen content of the surrounding space.

[0028] The gas outlet device 5 includes a deozonizer 51 for decomposing ozone, an air inlet pipe 53 and an air outlet pipe 55. The deozonizer 51 has an air inlet 511 and an air outlet 513. The air inlet pipe 53 is connected to the ozone preparation device 3 and the air inlet 511. The air outlet pipe 55 is provided with an exhaust port 55A connected to the outside. The exhaust port 55A divides the air outlet pipe 55 into a first pipe section 551 connected to the air inlet pipe 53 and a second pipe section 553 connected to the air outlet 513. The first pipe section 551 is provided with a switch valve 555 for opening and closing the first pipe section 551. The deozonizer 51 has a preset resistance to the airflow. It should be noted that the preset resistance of the deozonizer 51 to the airflow refers to the resistance of the deozonizer 51 when it leaves the factory, which does not need to be specially set.

[0029] In some embodiments of the present invention, the exhaust port 55A is a manifold fixed on the outlet pipe 55 and connected to the outlet pipe 55. It is understood that in other embodiments, the exhaust port 55A can be a hole structure penetrating the wall of the outlet pipe 55, or a notch formed by cutting a portion of the outlet pipe 55.

[0030] The switch valve 555 opens and closes the first pipe section 551 to enable the gas outlet device 5 to achieve two working modes.

[0031] Specifically, when the switch valve 555 opens the first pipe section 551, the gas outlet device 5 is in the first working mode. In the first working mode, since the deozonator 51 has a preset resistance to the airflow, the ozone and oxygen provided by the ozone production device 3 are directly discharged from the exhaust port 55A through the air inlet pipe 53 and the first pipe section 551; when the switch valve 555 closes the first pipe section 553, the gas outlet device 5 is in the second working mode. In the second working mode, since the switch valve 555 closes the first pipe section 553, the ozone and oxygen provided by the ozone production device 3 overcome the resistance of the deozonator 51 to the airflow, so that the ozone and oxygen provided by the ozone production device 3 enter the deozonator 51 through the air inlet pipe 53 so that the ozone is decomposed into oxygen, and the decomposed oxygen is discharged from the exhaust port 55A through the second pipe section 553. In the whole process, the ozone production device 3 provides power for the gas flow.

[0032] In some embodiments of the present invention, the switch valve 555 is an ozone-resistant electromagnetic switch valve.

[0033] In some embodiments of the present invention, a diffuser port 1a is provided at a position of the housing 1 opposite to the exhaust port 55A, and the exhaust port 55A is connected to the outside through the diffuser port 1a, thereby shortening the diffusion distance of the gas discharged from the exhaust port 55A to accelerate the diffusion rate.

[0034] In some embodiments of the present invention, a diffusion fan 6 is further provided at the exhaust port 55A, and the diffusion fan 6 is used to quickly diffuse the gas discharged from the exhaust port 55A from the air diffusion port 1a, thereby further enhancing the diffusion rate.

[0035] In some embodiments of the present invention, the deozonizer 51 includes a gas-liquid separator 515 and an ozone decomposer 517 connected to the gas-liquid separator 515 , the air inlet 511 is disposed on the gas-liquid separator 515 , and the air outlet 513 is disposed on the ozone decomposer 517 .

[0036] In some embodiments of the utility model, the gas-liquid separator 515 is further provided with an overflow port 519 at the air inlet 511, and the first pipe section 551 is connected to the air inlet pipe 53 via the overflow port 519 and the air inlet 511. That is, the first pipe section 551 is connected to the overflow port 519, the overflow port 519 is connected to the air inlet 511, and the air inlet 511 is connected to the air inlet pipe 53, thereby realizing indirect communication between the first pipe section 551 and the air inlet pipe 53. It can be understood that in other embodiments, the first pipe section 551 can be directly connected to the air inlet pipe 53, and the closer the position where the first pipe section 551 is connected to the air inlet pipe 53 is to the ozone preparation device 3, the more conducive it is to improve the concentration of the discharged ozone.

The anode water tank 33 has an anode gas supply port 331 connected to the gas inlet pipe 53.

[0040] It should be noted that the closer the position where the first pipe section 551 is connected to the air inlet pipe 53 is to the ozone production device 3 , the closer the position where the first pipe section 551 is connected to the air inlet pipe 53 is to the anode air supply port 331 .

[0044] In some embodiments of the utility model, at least one wall-mounted slot 11 is provided on the housing 1. The wall-mounted slot 11 is used to enable the aerator to be mounted on a wall. The housing 1 thus configured enables the aerator to be mounted on a desktop or on a wall to meet different installation environment requirements.

Among them, the controller 7 can control the water supply pump 37 to start and close at a preset water supply efficiency (i.e., the water supply volume per unit time) or at a preset interval time working duration (the starting time is based on the time when the ozone generator 31 starts working).

[0046] In some embodiments of the present invention, a plurality of heat dissipation holes 12 for dissipating heat of the controller 7 are also provided through the housing 1 at positions corresponding to the second cavity 1C.
