[0032] 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.

[0033] Some embodiments of the present utility model disclose a humidifier 100, such as Figure 1-Figure 8 As shown, it is safer than the known humidifiers in the prior art.

[0034] The humidifier 100 includes a base 10 . The base 10 is provided with an air outlet 101 , and the air outlet 101 has an air outlet 102 .

[0035] The humidifier 100 further includes a protective cover 20 . The protective cover 20 is slidably disposed on the air outlet 101 .

[0036] The humidifier 100 further includes an air duct cover 30. The air duct cover 30 has an air outlet cavity 301, in which the air outlet 102 and the protective cover 20 are disposed. An abutment portion 302 cooperating with the protective cover 20 is disposed in the air outlet cavity 301.

[0037] The humidifier 100 further includes a reset member 40. The reset member 40 is disposed between the protective cover 20 and the air outlet 101. When the air duct cover 30 is assembled to the base 10, the abutment portion 302 drives the protective cover 20 to open the air outlet 102; when the air duct cover 30 is detached from the base 10, the reset member 40 drives the protective cover 20 to cover the air outlet 102.

[0038] According to the principle of the present humidifier 100, by arranging a protective cover 20 at the air outlet 102, the protective cover 20 can move up and down relative to the air outlet portion 101 to open the air outlet 102 or cover the air outlet 102, that is, when the air duct cover 30 is assembled to the base 10, the abutment portion 302 in the air outlet cavity 301 will drive the protective cover 20 downward to open the air outlet 102, and at this time the air outlet 102 can normally discharge air to transport mist; when the air duct cover 30 is detached from the base 10, the reset member 40 will drive the protective cover 20 upward to cover the air outlet 102 to prevent water from splashing into the fan 50 when cleaning the water storage tank 106 of the present humidifier, which can better protect electrical equipment and improve the safety of the present humidifier 100.

[0039] Optionally, the reset member 40 may be a spring, which has a simple structure, is easy to manufacture, and reduces the manufacturing difficulty.

[0040] like Figure 3-Figure 6As shown, optionally, two air outlets 102 are provided, and the two air outlets 102 are arranged one by one on the opposite side walls of the air outlet portion 101. In this way, the humidifier 100 can be formed with two air outlets 102, and the two air outlets 102 can discharge air at the same time, which can increase the air output of the humidifier 100 and further improve the atomization effect.

[0041] Optionally, the protective cover 20 is annular and is sleeved on the circumferential outer side of the air outlet portion 101. In this way, the two air outlets 102 can be opened and covered at the same time.

[0042] like Figure 3 and Figure 5 As shown, optionally, the humidifier 100 further includes two fans 50, and the air outlet portion 101 has two air outlet channels 103, the two air outlet channels 103 are connected to the two air outlets 102 in a one-to-one correspondence, and the air outlets of the two fans 50 are connected to the two air outlet channels 103 in a one-to-one correspondence. In this way, the two fans 50 can independently discharge air from the two air outlets 102 through the two air outlet channels 103, and the two fans will not affect each other and offset each other to reduce the air volume; and the two fans 50 can further increase the air volume of the humidifier 100.

[0043] like Figure 3 and Figure 5 As shown, optionally, the protective cover 20 is annular. In a preferred embodiment, the protective cover can be in a square ring shape. An abutment plate 201 is provided between two inner side walls arranged opposite to each other in the protective cover 20; the air outlet portion 101 has a receiving cavity 104, and the receiving cavity 104 extends from the air outlet portion 101 toward the top side of the air duct cover 30 and the two opposite sides arranged opposite to each other; when the air duct cover 30 is assembled to the base 10, the abutment portion 302 can penetrate into the receiving cavity 104 and act on the abutment plate 201 to drive the protective cover 20 to open the air outlet 102. In this way, the abutment plate 201 of the protective cover 20 can be assembled into the accommodating cavity 104 of the air outlet portion 101, and when the air duct cover 30 is assembled to the base 10, the abutment portion 302 will penetrate into the accommodating cavity 104, driving the abutment plate 201 on the protective cover 20 downward, and then driving the protective cover 20 downward to open the air outlet 102. With such an arrangement, the structure will be more compact and the volume of the entire humidifier 100 can be reduced.

[0044] Optionally, the abutting portion 302 is cylindrical, and the abutting plate 201 includes a cylindrical abutting disk 202 that cooperates with the abutting portion 302 , and the radius of the abutting disk 202 is larger than that of the abutting portion 302 .

[0045] like Figure 3 , Figure 5 , Figure 7 and Fig. 9As shown, optionally, a cover step portion 203 is provided at the top of the protective cover 20, and a top cover 107 is detachably connected to the top of the air outlet 101. A through hole 108 is provided in the top cover 107 along its own height, and the through hole 108 is connected to the accommodating cavity 104; a convex strip 109 for abutting against the cover step portion 203 is provided on the top cover 107 toward the bottom of the protective cover 20. In this way, when the air duct cover 30 is detached from the base 10, the reset member 40 will drive the protective cover 20 upward to cover the air outlet 102, and the convex strip 109 of the top cover 107 can also abut against the cover step portion 203 of the protective cover 20, further enhancing the waterproof performance.

[0046] Optionally, a cushion layer 105 is provided at the bottom of the circumferential outer side of the air outlet portion 101. In this way, when the abutting portion 302 drives the protective cover 20 downward, the cushion layer 105 is provided for buffering to avoid direct impact on the base 10.

[0047] Optionally, a water storage tank 106 is provided on the top of the base 10, the air outlet 101 is provided beside the water storage tank 106, and the air outlet 102 is higher than the notch of the water storage tank 106 in the height direction of the humidifier 100. In this way, the water in the water storage tank 106 can be effectively prevented from directly flowing into the air outlet 102, and the waterproof performance is better.

[0048] Optionally, humidifiers currently on the market can generally be classified into ultrasonic humidifiers, electrothermal humidifiers, or composite humidifiers, etc. Among them, ultrasonic humidifiers are humidifiers that atomize water through ultrasonic waves and disperse the water mist into the air, while electrothermal humidifiers are humidifiers that vaporize water through electric heating to produce steam, and composite humidifiers are humidifiers that use more than two principles to achieve humidification functions at the same time. In this regard, the humidifier 100 can be an ultrasonic humidifier, an electrothermal humidifier, or a composite humidifier with both ultrasonic and electrothermal modes.

[0049] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
