The electric control module is electrically connected with the atomization generator 11 to control the atomization generator 11 to generate mist, and the electric control module is electrically connected with the air supply mechanism 30 to control the air supply mechanism 30 to supply air into the fogging chamber 10. The electronic control module specifically comprises a circuit board, a control switch and other components, and is used for controlling the working state of each electric component (such as the atomization generator 11, the indicator light and the like) in the humidifier.

After mist is generated in the first mist chamber 101, the mist can relatively stably rise to the second mist chamber 102, and the air supply mechanism 30 supplies air into the second mist chamber 102 to sufficiently mix the air flow and the mist, and then flows and mixes further in the third mist chamber 103, and is ejected from the spray opening 12.

By dividing the atomizing chamber 10 into three parts, the mist generated by the atomizing generator 11 and the air flow of the air supply mechanism 30 can be fully mixed, so that the mist sprayed from the atomizing nozzle 12 is more uniform, the visual effect of the mist is improved, and the mist of the humidifier has more aesthetic property.

In some embodiments, the humidifier is generally cylindrical in shape. Referring to fig. 3 and 7, the humidifier includes an upper case 1 and a lower case 2, a water storage chamber 20 is formed in the upper case 1, and a mist generating chamber 10 is defined by the upper case 1 and the lower case 2; the lower shell 2 forms an electric control chamber 50, and the electric control module and the air supply mechanism 30 are arranged in the electric control chamber 50.

Illustratively, the first mist compartment 101 is formed entirely in the upper housing 1, the third mist compartment 103 is formed entirely in the lower housing 2, and the second mist compartment 102 is defined by the upper housing 1 and the lower housing 2 together.

The third mist compartment 103 is located inside the inner casing and the reservoir compartment 20 is located between the outer and inner casings.

The matching position between the upper shell 1 and the lower shell 2 is set as a step surface, so that the upper shell and the lower shell are more stable after being assembled, and the sealing performance of the fogging chamber 10 is better.

In some embodiments, the first mist chamber 101, the second mist chamber 102 and the third mist chamber 103 are distributed from bottom to top, so that the mist generated by the atomizing generator 11 is diffused from bottom to top, and this diffusion mode is favorable for uniformity after the mist is mixed with the air flow delivered by the air supply mechanism 30.

In some embodiments, the second mist chamber 102 comprises a first mist mixing chamber 1021 and a second mist mixing chamber 1022 that are in communication with each other; the first mist mixing chamber 1021 and the second mist mixing chamber 1022 are distributed in the left-right direction in fig. 3, the first mist mixing chamber 1021 is located directly above the first mist chamber 101, the second mist mixing chamber 1022 is located obliquely above the first mist chamber 101, and the air supply mechanism 30 communicates with the second mist mixing chamber 1022.

Therefore, the mist in the first mist chamber 101 firstly enters the first mist mixing chamber 1021 after rising, and then is gradually mixed with the air flow in the second mist mixing chamber 1022, so that the arrangement can prevent the air flow of the air supply mechanism 30 from directly blowing to the first mist chamber 101, the mist supply and the air supply are relatively separated, the direct collision between the air and the mist is reduced, and the stability of the mist generated by the atomization generator 11 is facilitated.

In some embodiments, the third mist chamber 103 is surrounded by the delivery pipe, and the center of the third mist chamber 103 is offset from the center of the first mist chamber 101. This arrangement can prevent or reduce the possibility that the condensed water drops on the atomizing generator 11 to affect the stability of the mist produced when the condensed water is generated on the inner wall of the third mist chamber 103.

In some embodiments, a sound attenuating member 40 is disposed above the atomizing generator 11. The sound attenuating member 40 may serve to reduce the noise of the aerosol generator 11, making the humidifier quieter in use.

Illustratively, the sound attenuating member 40 is detachably disposed above the atomizing generator 11. That is, the muffler member 40 is a separate member that can be fitted to the inner wall of the first mist chamber 101 during assembly and is directly inserted above the mist generator 11. Of course, the silencing part 40 and the inner wall of the first fog chamber 101 may be integrally formed by those skilled in the art.

In some embodiments, referring to fig. 4, the sound attenuating element 40 includes an inserting portion 41, a bracket 42 and a first water baffle 43, wherein two ends of the bracket 42 are respectively connected to the inserting portion 41 and the first water baffle 43; the first water baffle 43 can block water drops dropping from the upper part, so that the water drops are prevented from dropping on the atomization generator 11, and the stability and the reliability of fog generation of the atomization generator 11 are further guaranteed.

The muffler member 40 is inserted above the atomizing generator 11 through the insertion portion 41, and it is not necessary to provide a fastening member such as a screw between the muffler member 40 and the inner wall of the first mist chamber 101.

The number of the brackets 42 is plural, and on one hand, the brackets play a role of supporting the first water baffle 43, and on the other hand, the brackets can uniformly disperse the mist generated by the atomizing generator 11. The cartridge 41 has an annular shape, and the annular cartridge 41 is provided around the atomization generator 11.

In some embodiments, the second water baffle 45 is connected to the middle of the vertical connecting rib 44, and the second water baffle 45 is provided with a through hole 451. The second water baffle 45 is arranged in the middle of the connecting rib plate 44, so that the mist outlet effect of the atomization generator 11 can be further improved, and the working stability of the atomization generator 11 is ensured. The through holes 451 allow part of the mist to pass therethrough, which is advantageous for improving the uniformity of the mist after rising.

In some embodiments, referring to fig. 3, the sound attenuating member 40 extends from the first mist chamber 101 to the second mist chamber 102. For example, the height of the sound-deadening member 40 exceeds the height of the first mist compartment 101, the top of the sound-deadening member 40 is located in the second mist compartment 102, and the bottom of the sound-deadening member 40 is located in the first mist compartment 101.

The inner sidewall may be the inner sidewall closest to the air outlet pipe 36, and the mist generated by the atomizing generator 11 rarely flows between the air outlet of the air outlet pipe 36 and the inner sidewall, and especially when the air outlet of the air pipe 36 is used for discharging air, the mist is hardly generated at the position.

The air outlet of the air outlet pipe 36 faces back to the third mist chamber 103, so that condensed water in the mist generating chamber 10 can be prevented from dripping into the air outlet pipe 36, and the air outlet of the air pipe 36 can be prevented from directly blowing mist in the mist generating chamber 10, so that the mist in the mist generating chamber 10 can more uniformly rise to the mist spraying opening 12 to be sprayed, and the mist generating effect is improved.

In some embodiments, the air outlet pipe 36 has a fan-shaped air outlet channel therein, and the air outlet is opened on the arc surface of the air outlet pipe 36. The structure makes the air outlet of the air outlet more dispersed, thereby being beneficial to fully mixing with the mist of the mist generating chamber 10 and further improving the mist outlet effect.

In some embodiments, referring to fig. 3, the third mist chamber 103 is formed by a duct which is enclosed by a portion of the inner casing, that is, a portion of the inner casing has a tubular structure. The tail end of the delivery pipe is turned inwards and retracted towards the third fog chamber 103, and the spraying port 12 is positioned at the tail end of the delivery pipe. The end of the delivery tube may be fitted with an outlet nozzle so that the spray outlet 12 is located on the outlet nozzle. The mist outlet nozzle is detachably connected with the conveying pipe, and users can replace the mist outlet nozzles of different types according to requirements.

In some embodiments, the third mist compartment 103 is surrounded by a delivery tube, and the top of the water storage compartment 20 has a filler 21, and the delivery tube extends from the filler 21. Therefore, when the humidifier is used, the mist is conveyed in the inner channel of the conveying pipe, and the water is arranged outside the conveying pipe.

In some embodiments, the top plate 22 of the water storage chamber 20 is a concave curved plate, and the water filling opening 21 is located at the center of the top plate 22, so that the water filling of the humidifier is facilitated.

An annular baffle plate 23 is arranged outside the conveying pipe, and the annular baffle plate 23 is positioned above the water filling opening 21 and forms a space with the top plate 22.
