After the lower insulation member 3 and the upper insulation member 4 are fixedly connected, a closed insulation cavity 26 is formed between the lower half insulation groove 32 and the upper half insulation groove 41. The insulation cavity 26 can isolate the cold water in the inner cavity of the water tank 1 from the hot water in the heating atomization cavity 21, effectively blocking the heat loss of the liquid after heating, having a heat preservation and heat insulation effect, and further reducing the energy consumption of the humidifier.

[0030] The lower end opening of the lower thermal insulation component 3 is provided with a lower mist outlet 33 at the upper end; the lower end of the upper thermal insulation component 4 is provided with a middle mist inlet 42 connected to the lower mist outlet 33, and the upper end is provided with a middle mist outlet 43; the lower end of the mist outlet component 5 is provided with an upper mist inlet 51 connected to the middle mist outlet 43, and the upper end is provided with an upper mist outlet 52, and the upper mist outlet 52 can be connected to the mist outlet duct to facilitate the discharge of warm mist. The lower mist outlet 33, the middle mist inlet 42, the middle mist outlet 43, the upper mist inlet 51 and the upper mist outlet 52 constitute the mist outlet channel 24. In this embodiment, the upper end of the upper thermal insulation member 4 is provided with an annular side wall 44 extending vertically upward, and the annular side wall 44 is provided with a plurality of second air inlets 45, and the side wall of the mist outlet member 5 is provided with a plurality of the first air inlets 25, and the first air inlet 25 and the second air inlet 45 are used to introduce external air into the heating atomization chamber 21 to circulate the air and improve the mist outlet efficiency. In addition, the first air inlet 25 and the second air inlet 45 are arranged in a staggered manner. Since the ultrasonic atomizer 12 will vibrate during operation, some hot water will splash out, and the first air inlet 25 and the second air inlet 45 are arranged in a staggered manner to prevent hot water from splashing out from the first air inlet 25.

[0031] A plurality of downward vertical snap arms 53 are provided at the edge of the upper mist inlet 51, and snap hooks 54 are provided at the ends of the snap arms 53.

[0032] As a further improvement of the present invention, an annular transverse portion 55 extending laterally outward is provided at the edge of the upper mist outlet 52, and an annular vertical portion 56 extending vertically downward is provided at the end of the annular transverse portion 55. After assembly, the upper end of the annular side wall 44 abuts against the bottom of the annular transverse portion 55, and the inner wall of the annular vertical portion 56 and the outer wall of the annular side wall 44 are interference fit, and the assembly structure is simple. In this embodiment, an annular extension portion 57 extending upward and outward is provided at the end of the annular transverse portion 55, and the upper mist outlet 52 is higher than the annular transverse portion 55. The annular extension portion 57 is higher than the upper mist outlet 52, and an annular water storage tank is formed between the annular transverse portion 55, the annular extension portion 57 and the edge of the upper mist outlet 52. During operation, a mist outlet duct 6 for discharging mist is installed on the top of the annular extension portion 57, refer to Fig. 9 The dotted arrow in the figure indicates the flow direction of the splashed hot water. The lower end of the mist outlet duct 6 is provided with an annular connecting portion 61 matching the shape of the annular extension portion 57. After assembly, the annular connecting portion 61 is inserted into the annular water storage tank, and the outer wall of the annular connecting portion 61 fits with the inner wall of the annular extension portion 57. Due to the vibration of the ultrasonic atomizer 12, a small amount of hot water will splash out from the upper mist outlet 52, and the splashed hot water flows along the inner wall of the mist outlet duct 6 to the annular connecting portion 61, and then the hot water flows into the annular water storage tank. When the water level of the annular water storage tank is higher than the upper mist outlet 52, the water in the annular water storage tank naturally flows into the heating atomization chamber 21, which plays a role in recovering hot water, reducing the loss of hot water, and reducing the energy consumption of the humidifier.

[0033] A water inlet channel 27 connecting the inner and outer sides of the heating atomizing chamber 21 is provided on one side of the lower thermal insulation component 3.

After assembly, one end of the limiting portion 28 abuts against the front end surface of the one-way valve 23 to play a one-way blocking role. Specifically, when the water level of the heating atomizing chamber 21 is higher than the height of the one-way valve 23, the pressure applied by the hot water of the heating atomizing chamber 21 to the one-way valve 23 is resisted by the limiting portion 28; and when the water level of the heating atomizing chamber 21 is lower than the height of the one-way valve 23, the pressure applied by the hot water of the heating atomizing chamber 21 to the one-way valve 27 is less than the pressure applied by the cold water of the water tank 1 to the one-way valve 23, and the rear end surface of the one-way valve 23 is not blocked, so that it is pushed open by the cold water of the water tank 1, thereby achieving an automatic water adding effect. In this embodiment, the one-way valve 23 includes a baffle 231 and a hanging ear 232 located at the upper end of the baffle 231 and extending laterally outward on both sides. The top of the water inlet channel 27 is provided with a downwardly recessed groove 29, and the hanging ear 232 is installed on the groove 29; the outer wall of the upper thermal insulation component 4 is provided with a limit plate 46 extending vertically downward corresponding to the groove 29. After assembly, the lower end of the limit plate 46 abuts against the top of the one-way valve 23 to prevent the one-way valve 23 from falling, and the assembly structure is simple.

[0034] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
