[0026] Example 1

[0027] like Figures 1-5As shown, this utility model proposes an indoor air humidification and purification structure, including a duct 1, a guide plate 7, a storage box 13, a fan 14, a flow valve 17, and an air detection component. Filters are installed in both the air inlet and outlet of the duct 1, and an installation mechanism is provided on the duct 1. The installation mechanism includes a fixed base 2, a mounting bracket 4, and a drive component. The fixed base 2 is connected to the duct 1, and a splined shaft 3 is mounted on the fixed base 2. The mounting bracket 4 is rotatably connected to the splined shaft 3. The drive component is mounted on the mounting bracket 4 and drives the splined shaft 3. The drive component includes a motor 5. A rotating shaft is mounted on the mounting bracket 4 and rotatably connected thereto. The rotating shaft is perpendicular to the splined shaft 3, and a bevel gear is mounted on both the rotating shaft and the splined shaft. The two bevel gears mesh. The motor 5 is connected to the mounting bracket 4, and the output end of the motor 5 is connected to the rotating shaft. A guide sleeve A6 is installed inside the duct 1, and a guide plate 7 is installed in the central hole of the guide sleeve A6. A guide channel 71 connecting the air inlet and outlet of the duct 1 is provided on the guide plate 7. The guide channel 71 is a Tesla valve-shaped channel, and the flow direction of the Tesla valve-shaped channel is reversed. A cover plate 8 is provided on the guide plate 7, and a pulsed plasma generator 9 with its output end extending into the guide channel 71 is provided on the cover plate 8. One end of a storage box 13 is inserted into the duct 1 and located between the air inlet of the duct 1 and the guide plate 7. The storage box 13 has several ventilation holes 131 and is filled with adsorbent, including but not limited to activated carbon 132. A wedge-shaped locking block 15 is slidably connected to the storage box 13 and is slidably connected to the inner wall of the duct 1. A lever 16 is slidably installed on the storage box 13 and is connected to the wedge-shaped locking block 15. A fan 14 is installed inside the duct 1 and located between the guide plate 7 and the air outlet of the duct 1. A flow valve 17 is installed on the duct 1, and its output end is connected to an atomizing nozzle 18, which is located inside the duct 1 and between the guide plate 7 and the air outlet of the duct 1. An air detection assembly is installed on the duct 1, with its detection end located between the air inlet of the duct 1 and the guide plate 7. The air detection assembly includes an air detector 19 and a controller. The air detector 19 is equipped with a temperature sensor, a humidity sensor, and a PM2.5 sensor, etc. The controller is electrically connected to the air detector 19, and is also electrically connected to the fan 14, the flow valve 17, and the pulse plasma generator 9. An alarm is also installed inside the duct 1 and is electrically connected to the controller.

[0028] In this embodiment, after fixing the mounting bracket 4 of the device, the device is connected to the power supply, and an external water pipe is connected to the input end of the flow valve 17. The fan 14 is started. When the fan 14 is working, indoor air passes through the filter and enters the air duct 1 through the air inlet. Then, the air enters the storage box 13 through the vent 131 and passes through the pores of the activated carbon 132 into the Tesla valve-shaped guide channel 71. Since the air flows in the reverse direction in the Tesla valve-shaped channel, its flow rate is slow. At this time, the pulse plasma generator 9, which is in working condition, has sufficient time to sterilize the air in the guide channel 71. The principle of sterilization by the pulse plasma generator is to generate plasma through a high-voltage electric field. The active particles in the plasma, such as electrons, ions, and free radicals, have strong oxidation and reduction capabilities, which can react with the proteins, nucleic acids, and other biological macromolecules in microorganisms, destroying their structure, thereby achieving the purpose of disinfection and sterilization. The sterilized air enters the room under the action of the fan 14, thereby gradually reducing the content of harmful substances in the indoor air. When the air detector 19 detects low air humidity, the flow valve 17 opens, allowing water from the pipe to enter the atomizing nozzle 18, where it is atomized and sprayed out, mixing with the disinfected air. The higher humidity air entering the room effectively increases indoor humidity. Since activated carbon 132 is a consumable, if the air detector 19 detects a high concentration of particulate matter in the air after multiple cycles, an alarm sounds. Staff simply need to move the lever 16 to retract the wedge-shaped locking block 15, then remove the storage box 13 and replace the activated carbon 132 inside. During operation, the motor 5 drives the air duct 1 to rotate around the splined shaft 3, thereby changing the direction of airflow.

[0029] Example 2

[0030] like Figure 4 As shown, the indoor air humidification and purification structure proposed in this utility model, compared with the first embodiment, has a guide sleeve B10 installed inside the air duct 1, a slot with an opening facing downwards installed on the guide sleeve B10, a spring rod 11 installed on the upper wall of the slot, and a pressure plate 12 slidably connected to the guide sleeve B10. The pressure plate 12 is connected to the movable end of the spring rod 11, and the pressure plate 12 is inserted into the storage box 13 and slidably connected to its inner wall.

[0031] In this embodiment, since there are gaps between the activated carbon 132, if the activated carbon 132 in the storage box 13 is not fully loaded, there will be an open channel above the storage box 13. After the air enters the air duct 1 through the air inlet, it will preferentially pass through the open channel, which will prevent the activated carbon 132 from adsorbing the flowing air. After the pressure plate 12 is installed, the activated carbon 132 is squeezed by the elastic and telescopic pressure plate 12, which can eliminate the open channel and improve the adsorption efficiency of the activated carbon 132.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
