In the specific implementation process, the number of air inlets 21 is set to two, and the two air inlets 21 are symmetrically arranged on opposite sides of the front panel 2. A second ultraviolet lamp is arranged in one end of the mounting frame 3 close to the upper cover 10, and the ultraviolet wavelength of the second ultraviolet lamp is 360-390nm. An unpowered fan for enhancing the gas reaction of the disinfection generator is arranged in the mounting frame 3. The wind direction of the unpowered fan is not fixed and can rotate freely.

[0028] It should be noted that ozone and hydrogen peroxide are decomposed by the first ultraviolet lamp 7, and the blower 8 plays a blowing role, so as to conveniently discharge the oxidative disinfection factors produced by the disinfection generator. The two first generating boxes 4 can effectively increase the working time of the disinfection generator, thereby providing a disinfection generator, increasing its service life and enhancing the purification performance.

[0029] It should also be noted that a photocatalytic material is provided in one end of the mounting frame 3 close to the upper cover 10. The photocatalytic material may be titanium dioxide or carbonitride. The long-mouth blower 8 is used to increase the wind pressure, while the wind speed is low, which can effectively reduce noise.

Ozone and hydrogen peroxide will intensify the reaction in a humid environment to generate more disinfection factor hydroxyl radicals. The final reaction port is the photocatalyst material of the titanium dioxide attachment layer, and a UVA ultraviolet lamp is provided in this area for irradiation and photolysis.

[0034] The upper cover 10 is in the disinfection factor emission area, and is equipped with a UVALED lamp that can effectively use UVA light to photolyze more hydroxyl free radicals within the range surrounded by the photocatalyst. At the same time, the UVA light does not cause any harm to the human body, thereby achieving the effect of increasing the disinfection effect without causing any harm to the human body.

[0044] like Figure 1 As shown, the ozone generator 5 includes an ozone generating head 51 and a high voltage generator 52 which are electrically connected to each other. The high voltage generator 52 transmits the generated high voltage to the ozone generating head 51, and the ozone generating head 51 is used to release the high voltage and generate ozone. In the specific implementation process, the number of ozone generating heads 51 is set to two, and the first split frame 32 is provided with a first mounting position 321 for mounting the ozone generating head 51.

[0045] like Figure 1 As shown, the number of LED lamps 11 is set to four, and a control circuit for controlling the four LED lamps 11 to work alternately is provided in the PCB board 6. In the specific implementation process, the LED lamp 11 is a UVA LED lamp.

[0046] like Figure 1 and Figure 2 As shown, a baffle 22 for air to enter the disinfection generator from below is provided at the air inlet 21. In the specific implementation process, the front panel 2 and the baffle 22 are an integrally formed structure.

[0047] The disinfection generator has built-in air carbon dioxide, TVOC, and PM2.5 detection modules to inform users of the current air conditions. The disinfection machine automatically adjusts the wind speed through microelectronic technology to increase the service life of the product. The disinfection generator uses a wireless data transmission module (WIFI, BT, NB, 4G / 5G) for data transmission.

[0048] Figure 4 Schematic diagram of the cross-sectional structure of a disinfection generator disclosed in this embodiment. Figure 4 As shown, the second split frame 33 is provided with an inner convex wall 335 for uniformly adjusting the wind pressure in the first channel 331, the second channel 332 and the third channel 333. The inner convex wall 335 is arranged in an arc shape. Through the arrangement of the inner convex wall 335, the wind pressure in the first channel 331, the second channel 332 and the third channel 333 is uniform, so that the disinfection generator produces the best quality disinfection factor and realizes the controllability of the quantity of the disinfection factor.

[0049] Working principle: Ozone and hydrogen peroxide are decomposed by the first ultraviolet lamp 7, and the blower 8 plays a blowing role to facilitate the discharge of the oxidative disinfection factors produced by the disinfection generator. The two first generating boxes 4 can effectively increase the working time of the disinfection generator, thereby providing a disinfection generator, increasing its service life and enhancing the purification performance.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
