[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, this utility model provides a technical solution: a household humidifier, comprising: a water tank 1, with a piston scraper 14 installed inside the water tank 1 for cleaning the inner wall of the water tank 1; a top cover 4 threadedly connected to the top of the water tank 1, with an air inlet 2 on the side of the top cover 4, a storage box 6 fixedly connected inside the top cover 4, a filter 7 installed inside the storage box 6 for filtering the air inlet 2, a turbine fan 9 installed in the middle of the storage box 6, and a light strip installed above the top cover 4 for use as a night light; a connecting rod 11 placed below the top cover 4, with germicidal lamps 12 installed on both sides of the connecting rod 11, the germicidal lamps 12 being ultraviolet germicidal lamps, and an ultrasonic atomizing head 13 fixedly connected to the bottom of the connecting rod 11.

[0024] It should be noted that this embodiment includes a controller and a touch switch. Water is placed inside the water tank 1, and the top cover 4 is rotated and installed on top of the water tank 1. The germicidal lamp 12 sterilizes the inside of the water tank 1, the ultrasonic atomizing head 13 atomizes the water, and the turbine fan 9 discharges the atomized water mist from the top of the top cover 4, thereby humidifying the room through the water mist. When the device needs to be used as an air purifier, the corresponding switches of the ultrasonic atomizing head 13 and the germicidal lamp 12 are turned off. By pushing the filter 7 downward, the filter 7 slides out from inside the storage box 6, and the filter 7 blocks the air inlet 2. The turbine fan 9 draws in outside air from the air inlet 2, discharges it through the middle of the storage box 6 to the top of the top cover 4, thereby achieving air purification. Furthermore, a light strip is installed on the top of the top cover 4. When used at night, it can be illuminated by controlling the switch, thus serving as a night light.

[0025] In one embodiment, a rubber ring is fitted on the outer side of the piston scraper 14, and a handle 15 is fixedly connected to the top of the piston scraper 14.

[0026] It should be noted that in this embodiment, the inner wall of the water tank 1 needs to be cleaned during long-term use. Due to its size, there will be hard-to-clean corners at the angle between the side wall and the bottom, which are difficult to clean. The piston scraper 14 is installed at the bottom of the water tank 1, and the outer side of the piston scraper 14 is in contact with the inner wall of the water tank 1 to prevent water from entering the bottom of the piston scraper 14 along the inner wall of the water tank 1. After wiping and cleaning the water tank 1, the opening of the water tank 1 is tilted downward, and the piston scraper 14 is pulled out through the handle 15. The piston scraper 14 is used to scrape the inside of the water tank 1 to clean it. After rinsing and cleaning the piston scraper 14, it is put back into the water tank 1.

[0027] In one embodiment, the top cover 4 has an air vent 10 at its top, the storage box 6 has an exhaust duct 17 in its middle, and the turbine fan 9 is fixed to the middle of the exhaust duct 17.

[0028] It should be noted that in this embodiment, the turbine fan 9 draws air into the exhaust duct 17 through the air inlet 2 and then exhausts it from the air outlet 10 at the top of the top cover 4, thereby filtering or humidifying the indoor air.

[0029] In one embodiment, an annular plate 3 is installed above the top cover 4, and a plurality of lifting rods 5 are fixedly connected to the bottom of the annular plate 3. The lifting rods 5 pass through the top cover 4 and are slidably connected to the top cover 4. A metal ring is fixed to the bottom of the lifting rods 5, and the filter screen 7 is threadedly connected to the bottom of the metal ring.

[0030] It should be noted that in this embodiment, the filter 7 is a HEPA filter, with support rings installed at both its top and bottom. A metal rod is fixed between the support rings, and the HEPA filter is installed between the support rings. An external thread is provided on the outer side of the upper support ring, and a metal groove with an internal thread is provided at the bottom of the metal ring to thread the filter 7 to the metal ring. A rubber plate is fixed to the bottom of the lower metal ring to seal the storage box 6 when the filter 7 is raised. The lifting rod 5 is raised and lowered by the annular plate 3, thereby adjusting the height of the filter 7 and storing it in the storage box 6 to prevent water mist from contacting the filter 7.

[0031] In one embodiment, an operating box 16 is fixedly connected to the top of the water tank 1.

[0032] It should be noted that in this embodiment, the light strip is attached to the outer slope of the operating box 16, and the controller and battery electrically connected to the turbine fan 9 are installed inside the operating box 16. A touch switch is installed on the top of the operating box 16.

[0033] In one embodiment, the bottom of the top cover 4 is threadedly connected to a filter plate 8, and the connecting rod 11 is fixedly connected to the bottom of the filter plate 8.

[0034] It should be noted that in this embodiment, a wire for powering the germicidal lamp 12 and the ultrasonic atomizing head 13 is installed in the middle of the connecting rod 11. The connecting rod 11 is supported by the filter plate 8, so that the water mist atomized by the ultrasonic atomizing head 13 enters the exhaust channel 17 through the through hole of the filter plate 8, and is discharged by the turbine fan 9 through the air outlet 10.
