[0037] Referring to Figures 1 to 14 , this embodiment provides a humidifier 100 with a vapor mist heating function. The humidifier 100 with a vapor mist heating function includes: a liquid storage tank 1, a mist outlet air duct 2 disposed within the liquid storage chamber 1, an atomizing assembly 3 disposed within the liquid storage tank 1, and a top cover assembly 4. The top cover assembly 4 is electrically connected to the atomizing assembly 3 via a wire 5. The top cover assembly 4 is connected to the upper opening of the liquid storage tank 1. In some embodiments, the top cover assembly 4 may also be an integral part of the liquid storage tank 1.

[0038] In one embodiment, the humidifier 100 with a vapor mist heating function includes: a liquid storage tank 1, an atomizing assembly 3 and a heating element 61. The liquid storage tank 1 is provided with a liquid storage chamber 11, the atomizing assembly 3 is arranged in the liquid storage chamber 11, and the heating element 61 is arranged in the liquid storage chamber 11 or on the liquid storage tank 1. The heating element 61 is used to heat the vapor mist after atomization by the atomizing assembly 3 or to preheat the airflow input from the outside into the liquid storage chamber 11. The airflow input from the outside into the liquid storage chamber 11 is used to increase the flow velocity of the vapor mist in the liquid storage chamber 11, thereby increasing the amount of mist output. The humidifier 100 with a vapor mist heating function of this embodiment heats the input airflow or heats the vapor mist after atomization by the heating element 61, and finally realizes an increase in the temperature of the vapor mist in the output environment, so as to be suitable for humidification needs in cold environments or seasons. Rather than preheating the atomized liquid as in the prior art, the humidifier with a vapor mist heating function in this embodiment has higher heating efficiency than the prior art, does not require a high-power heating element, and has lower energy consumption. In this embodiment, the vapor mist refers to the atomized liquid after being atomized by the atomizing assembly 3, and the atomized liquid mainly includes pure water or liquid essential oil with fragrance.

[0039] Among them, the liquid storage tank 1 is also provided with an air inlet duct, and the heating element 61 is arranged in the air inlet duct. It should be noted that the air inlet duct referred to here can be a physical air inlet pipe independent of the liquid storage tank 1, or it can be an air inlet duct structure arranged in the liquid storage tank, or it can be the cavity part above the liquid storage chamber of the liquid storage tank that is not filled with atomized liquid and the cavity part between the mist outlet. That is, under this embodiment, the heating element 61 is arranged in the vapor mist output channel after atomization by the atomization component 3, and heats the atomized vapor mist. The heating element 61 can be set at any position in the vapor mist output channel.

[0040] In one embodiment, the humidifier 100 with a vapor mist heating function further includes a supply fan 44, the air outlet of which is connected to an upper air inlet duct, and the heater 61 is disposed at the air inlet of the supply fan 44, or alternatively, at the air outlet of the supply fan 44. In this embodiment, the supply fan 44 functions to draw external air into the liquid storage chamber 11, thereby increasing the flow rate of the atomized vapor mist within the liquid storage chamber 11 and thereby increasing the output mist volume. Placing the heater 61 at the air inlet or outlet of the supply fan 44 preheats the delivered airflow, which is then delivered to the atomizing assembly 3. The heated vapor mist is then carried along with the heated vapor mist and output to the environment. The hot air mixes with the vapor mist, thereby increasing the temperature of the vapor mist and achieving the purpose of heating the vapor mist. Similarly, the speed and efficiency of heating the airflow are much higher than those of heating the atomized liquid, thereby reducing waiting time and energy consumption.

[0041] In another embodiment, the liquid storage tank 1 is further provided with a mist outlet pipe, and the heating element 61 is arranged in the mist outlet pipe or at the mist inlet or mist outlet of the mist outlet pipe. In this embodiment, a mist outlet pipe is added to the liquid storage tank 1, and the mist outlet pipe is used to collect the atomized vapor mist, and its function is also to increase the amount of mist output. It can be understood that in this embodiment, the mist outlet pipe can be a solid pipe independent of the liquid storage tank 1, or a pipe structure provided on the liquid storage tank 1, or a cavity portion above the liquid storage chamber 11.

[0042] Please refer to Figures 3 to 5 again. A mist outlet ventilation pipe 2 is also provided in the liquid storage chamber 11 of the liquid storage tank 1. The mist outlet ventilation pipe 2 is a physical pipe independent of the liquid storage tank 1. A mist outlet chamber 212 and a ventilation chamber 222 are provided in the mist outlet ventilation pipe 2. The heating element 61 is arranged in the ventilation chamber 222 and / or the mist outlet chamber 212. Specifically, the mist outlet air duct 2 includes: a mist outlet pipe portion 21 and a ventilation pipe portion 22. The ventilation pipe portion 22 is a pipe body protruding outward from the side wall of the mist outlet pipe portion 21. A gap is formed at the intersection of the mist outlet pipe portion 21 and the ventilation pipe portion 22 in the length direction. The air supply fan 44 sends external air from the top of the ventilation chamber 222 downward to the atomizing assembly 3. After being reflected at the atomizing assembly 3, the air carries the atomized vapor and is output upward along the mist outlet chamber 212 to the environment. When the atomizing assembly 3 is arranged in the mist outlet chamber 212, the mist outlet ventilation pipe 2 is further provided with a liquid inlet hole for external atomized liquid to flow into the mist outlet chamber 212. In this embodiment, the bottom of the mist outlet chamber 212 and / or the ventilation chamber 222 is respectively provided with a liquid inlet hole 211 (221).

[0043] The bottom end of the mist outlet ventilation pipe 2 abuts against the bottom of the liquid storage chamber 11 , and the top end is connected to the top cover assembly 4 .

[0044] Please refer to Figure 11 again. The top cover assembly 4 includes: a top cover 41, a supply fan 44 arranged inside the top cover 41, and the supply fan 44 is arranged inside the top cover 41 through a waterproof shell 45. A mist outlet 412 and an air inlet 411 are provided on the top cover 41. The mist outlet 412 is connected to the mist outlet channel, and the air inlet 411 is connected to the air inlet of the supply fan 44 and the ventilation cavity 222. An end cap 42 is also provided above the mist outlet 412, and the end cap 42 is used to disperse the output vapor mist. A switch module 43 is also provided in the top cover 41, and the switch module 43 is electrically connected to the atomization assembly 3 through a wire 5. In this embodiment, the top cover 41 includes: a bottom shell 401 and an upper shell 402 that is clamped to the bottom shell 401. The bottom shell 401 and the upper shell 402 together enclose an installation cavity for arranging components such as the supply fan 44.

[0045] Referring again to Figure 13 , in the second heating element position, the heating element 62 is positioned at the air inlet of the blower fan 44. In the third position, as shown in Figure 14 , a heating element 63 is positioned at the air outlet 441 of the blower fan 44. The bottom housing 401 is provided with a through hole 413 that communicates with the ventilation pipe 22. The heating element 63 is positioned at the air outlet 441 of the blower fan 44, thereby preheating the airflow entering the humidifier.

[0046] The mist outlet 412 is connected to the mist outlet cavity 221 , and the ventilation port 411 is connected to the ventilation cavity 222 .

[0047] Please refer to Figures 6 to 10 again. In this embodiment, the atomizer assembly 3 adopts a suspended atomizer assembly design. The atomizer assembly 3 includes a float 31. The float 31 is used to suspend the atomizer assembly 3 in the atomized liquid stored in the liquid storage chamber 11. The suspended atomizer assembly 3 can descend synchronously with the consumption of the atomized liquid, thereby keeping the atomizing surface of the atomizer sheet 32 ​​of the atomizer assembly 3 always at a set height below the liquid level of the atomized liquid. Generally, the set height is 10-90 mm below the liquid level. At this time, the atomizer sheet 32 ​​has a higher working efficiency and the mist output is also the largest.

[0048] Furthermore, the atomizer assembly 3 further includes: an atomizer sheet 32 ​​and an atomizer control circuit board 34. The float 31 is provided with a mist outlet chamber 311 and a liquid inlet channel 310. The atomizer sheet 32 ​​is disposed within the mist outlet chamber 311, and the liquid inlet channel 310 is connected to the mist outlet chamber 311. The heater 61 is disposed at the liquid inlet channel 310. Of course, it is understood that the heater 61 can also be disposed at any position within the mist outlet chamber 311.

[0049] The atomizer assembly 3 also includes a mounting bracket 35 disposed within the float 31. The atomizer plate 32 is connected to the mounting bracket 35. The atomizer control circuit board 34 is disposed within a shielding cover 33. The shielding cover 33 separates the atomizer control circuit board 34 from the atomizer plate 32 to prevent the oscillation signal from affecting other components. The atomizer control circuit board 34, the shielding cover 33, and the mounting bracket 35 are all sealed and embedded in the bottom of the float 31 using potting compound. The atomizing surface of the atomizer plate 32 is connected to the atomizer chamber 311, so that the atomized liquid directly contacts the atomizing surface of the atomizer plate 32 after entering the atomizer chamber 311.

[0050] It should be noted that, in other embodiments, the atomizing assembly 3 may also be fixedly disposed in the liquid storage chamber 11 or the mist outlet ventilation pipe 2 .

[0051] Wherein, the heating element 61 (62, 63) is a constant temperature heating element.

[0052] Referring again to Figure 6 , when a suspended atomizer assembly 3 is installed within the mist outlet ventilation duct 2, to facilitate wiring, the wire 5 of the atomizer control circuit board 34 is led out from the bottom of the float 31, then bent outward and routed within the ventilation cavity 222. The end of the wire 5 is ultimately electrically connected to the switch module, external control module, or power supply on the top cover assembly 4. This design eliminates the need for slots in the mist outlet ventilation duct 2 for routing the wires. Furthermore, the wire 5 acts as a limiter for the suspended atomizer assembly 3, preventing it from becoming entangled with the wire during the suspended lifting process, potentially affecting the lifting motion.

[0053] It is understandable that in other embodiments, in order to improve the heating effect on the steam mist, the heating element 61 (62 or 63) can be set in the air inlet channel and the mist outlet channel at the same time, and the number of settings can be increased or decreased as needed.

[0054] The humidifier with steam mist heating function of this embodiment heats the steam mist formed after atomization through a heating element, or preheats the airflow sent into the atomization channel, directly heating the steam mist or input gas, with faster heating speed, lower energy consumption and better user experience.

[0055] The above examples are merely used to further illustrate the technical content of this application to facilitate understanding by the reader, but do not limit the implementation of this application to these examples. Any technical extension or re-creation based on this application is protected by this application. The scope of protection of this application shall be based on the claims.
