[0001] The utility model relates to the technical field of humidification, in particular to a humidifier with double fans. Background Art
[0002] A humidifier is a household appliance that increases the humidity in a room and can humidify a designated room. Common humidifiers on the market include ultrasonic humidifiers and electric heating humidifiers; the ultrasonic humidifier uses a high-frequency oscillation plate (atomizing plate) to generate high-frequency vibrations, atomizes water into ultra-fine particles, and diffuses the water mist into the corresponding space through a small fan inside the machine to achieve the humidification effect; while the electric heating humidifier vaporizes water through electric heating to generate steam, and uses a pneumatic device to send the steam out for hot mist humidification.
[0003] In order to increase the atomization diffusion range, there are humidifiers on the market that assemble ultrasonic humidifiers and heating humidifiers on the same body, and mix the two types of mist in a mixing chamber at the outlet to increase the atomization amount. However, usually only one fan is set in the air duct to send out the mixed mist. Although the atomization amount is increased, the air output is reduced, so there is room for improvement.

DETAILED DESCRIPTION
[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0031] Since the humidifier in the prior art assembles the ultrasonic humidifier and the heating humidifier on the same body, the two types of mist are mixed in the mixing chamber at the outlet end to increase the atomization volume, but only one fan is provided in the body. The fan needs to deliver the mist generated by the ultrasonic wave and the mist generated by the heating type at the same time. The atomization volume is twice the original. The structure of the air duct will be improved to accommodate the ultrasonic atomization structure and the heating atomization structure. It can be seen that the air duct will inevitably be extended or larger in volume, but only one fan is still provided. Compared with the larger air duct, the wind force of one fan is obviously insufficient, resulting in a decrease in the air output.
[0032] Therefore, the inventors realized that designing a heater that retains both ultrasonic and heating atomization methods and can increase the air output will bring many benefits. Figure 1-Figure 5 As shown, the core of the embodiment of the utility model is embodied, and the air output is larger than that of the known humidifier in the prior art.
[0033] The humidifier 100 includes an atomizing air duct wall 10, which is surrounded by an atomizing air duct cavity 11. A baffle 12 is provided in the atomizing air duct cavity 11, and the baffle 12 divides the atomizing air duct cavity 11 into a first atomizing cavity 111 and a second atomizing cavity 112. With such a cavity structure, the atomizing air duct cavity 11 can be divided into a first atomizing cavity 111 and a second atomizing cavity 112 which are relatively independent and not connected by the baffle 12. Moreover, one of the first atomizing cavity 111 and the second atomizing cavity 112 is used to generate mist by ultrasonic waves, and the other is used to generate mist by heating.
[0034] The humidifier 100 also includes an air outlet duct wall 20, which is surrounded by an air outlet duct cavity 21. The first atomizing cavity 111 has a first air inlet 13 and a first air outlet 14, and the second atomizing cavity 112 has a second air inlet 15 and a second air outlet 16. The first air outlet 14 and the second air outlet 16 are connected to the air outlet duct cavity 21. With such an air outlet structure, the mist generated by the first atomizing cavity 111 and the second atomizing cavity 112 will not be directly mixed in the atomizing duct cavity 11, but will be sent to the air outlet duct cavity 21 through the respective first air outlet 14 and the second air outlet 16 for mixing, and then sent to the outside of the humidifier 100.
[0035] The humidifier 100 further includes a first fan 30 and a second fan 40. The first fan 30 is used to generate an airflow from the first air inlet 13 to the first air outlet 14 in the first atomizing chamber 111, and the second fan 40 is used to generate an airflow from the second air inlet 15 to the second air outlet 16 in the second atomizing chamber 112. With such a dual fan structure, the mist generated by the first atomizing chamber 111 will be supplied by the first fan 30 alone, and the mist generated by the second atomizing chamber 112 will be supplied by the second fan 40 alone. The dual fans can supply air to the mist generated by the ultrasonic and heating methods respectively, and the air output will be larger than that of the humidifier 100 in the prior art. In summary, the humidifier 100 of this embodiment can retain both ultrasonic and heating atomization methods to ensure sufficient atomization volume, and can also increase the air output, thereby improving the humidification efficiency of the humidifier 100.
[0036] like Figure 2-Figure 5 As shown, optionally, the first air outlet 14 is disposed on a side of the first atomizing chamber 111 close to the baffle 12, and the second air outlet 16 is disposed on a side of the second atomizing chamber 112 close to the baffle 12. In this way, the first air outlet 14 and the second air outlet 16 are very close to each other, so that the mist sent from the first air outlet 14 and the mist sent from the second air outlet 16 can be mixed to increase the amount of atomization.
[0037] like Figure 2-Figure 5 As shown, optionally, in the length direction of the humidifier 100, which is the X direction in the figure, the first atomizing chamber 111 and the second atomizing chamber 112 are arranged alternately. In this way, the structure is simple, easy to manufacture and reduce the manufacturing difficulty.

Of course, in some other embodiments, the first fan 30 and the second fan 40 can also be arranged separately from each other.

The ultrasonic atomization component 50 can be specifically composed of components such as a piezoelectric ceramic vibrator, an oscillator, a protective tube, and a main circuit board. The piezoelectric ceramic vibrator is the core component of the ultrasonic atomizer, which can convert an electrical signal into an oscillation signal to realize electronic high-frequency oscillation. This is a prior art and will not be described in detail here.
[0041] Optionally, a heating atomizing assembly 60 is provided in the second atomizing chamber 112, and the heating atomizing assembly 60 can atomize water by heating.

More optionally, the angle α between L1 and L2 preferably ranges from 90°≤α≤120°. In this way, the structure can be made more compact, the space occupied can be reduced, and the miniaturization of the humidifier 100 can be facilitated.
[0045] Optionally, the angle α between L1 and L2 may be 90°, 95°, 100°, 105°, 110°, 115° or 120°. Of course, in other embodiments, it may be other angle values within the range of 90°≤α≤120°.

[0047] Optionally, the center line between the second air inlet 15 and the heating atomizing assembly 60 is set to L3, and the center line between the second air outlet 16 and the heating atomizing assembly 60 is set to L4, wherein L3 and L4 are set at an angle. More optionally, the angle β between L3 and L4 preferably ranges from 90°≤β≤120°. In this way, the structure can be made more compact, the space occupied can be reduced, and the miniaturization of the humidifier 100 can be facilitated.
