Detailed Description

Referring to fig. 1 to 2 in combination, according to an embodiment of the present invention, there is provided an atomizing humidifier, including a humidifier housing 10 and an air flow driving part, wherein the humidifier housing 10 has an atomizing chamber 11 therein, an atomizer 12 is disposed in the atomizing chamber 11, and is capable of atomizing a water 101 in contact with the atomizer into a mist, the atomizing chamber 11 has a mist outlet channel 13, as can be understood, an inlet end of the mist outlet channel 13 is communicated with the atomizing chamber 11, and an outlet end thereof is a mist outlet 131, the air flow driving part includes an air flow driving blade 21, the air flow driving blade 21 is disposed in the mist outlet channel 13, the air flow driving blade 21 divides the mist outlet channel 13 into a positive pressure side (i.e., a side close to the mist outlet 131) and a negative pressure side (i.e., a side close to the atomizing chamber 11), the atomizer 12 is disposed on the negative pressure side of the air flow driving blade 21, so that the mist 100 generated by the atomizer 12 can be delivered from the mist outlet channel 13 to an external environment under the rotation driving of the air flow driving blade 21, and larger particles in the mist 100 can be separated from the mist 100 under the centrifugal force of the rotation of the air flow driving blade 21. In the technical scheme, the atomizer 12 is located on the negative pressure side of the airflow driving blade 21, the airflow driving blade 21 drives the water mist 100 to flow out of the humidifier in a pumping mode, and the mode of blowing out the water mist in a positive pressure mode in the prior art is omitted, so that large particles mixed in the water mist 100 can be thrown out under the centrifugal force action of the rotation of the airflow driving blade 21 when the water mist 100 flows out of the humidifier for humidification, only the small-particle water mist 100 is blown out, and the phenomenon that the water mist flowing out of a mist outlet of the humidifier in the prior art wets the ground or a table top is effectively avoided. It should be noted that the separated larger particle mist can be guided back to the atomizing chamber 11.

The airflow driving blade 21 preferably adopts a blade which drives airflow to flow axially, such as an axial flow blade, so as to be able to make full use of the rotating centrifugal force of this type of blade to throw out larger particles in the water mist 100, and in some cases, the oblique flow blade may also be used as an optional mode which can change the outflow angle of the water mist 100 to some extent, so as to meet different requirements of users. The diameter of the airflow driving blade 21 is increased to reduce the running rotating speed of the airflow driving blade, so that the wind noise can be greatly reduced on the premise of ensuring the wind quantity. Theoretically, the atomizer 12 may be a component capable of forming water mist, and may be an ultrasonic atomizer, which has a small volume, a compact structure, simple control and a good atomization effect.

In a specific embodiment, the airflow driving component further includes a rotary driving motor 22, an output end of a rotating shaft 23 of the rotary driving motor 22 is in driving connection with the airflow driving blade 21, the aforementioned driving connection may be in various detachable manners such as a threaded connection, a pin connection, an interference socket connection, and the like between a terminal end of the rotating shaft 23 and a hub of the airflow driving blade 21, and the rotary driving motor 22 is located outside the atomizing chamber 11. In this technical solution, the rotary drive motor 22 is disposed outside the atomizing chamber 11, so that the damage of the water mist 100 and even the water body 101 to the rotary drive motor 22 can be prevented, and the protection level of the rotary drive motor 22 (IP level, for example, a higher level waterproof fan, whose waterproof level needs to be IP 68) is reduced, that is, the drive of the blades can be realized by using a lower protection level motor, which obviously can reduce the manufacturing cost of the product.

In a preferred embodiment, a partition 14 is disposed in the humidifier housing 10, the partition 14 divides an internal space of the humidifier housing 10 into an atomizing chamber 11 and a closed electrical chamber 15, the swing driving motor 22 is mounted in the electrical chamber 15, other electrical components related to the humidifier, such as the control board 5 (which is used for controlling operation of the humidifier), are further assembled in the electrical chamber 15, an electrical connection side of the atomizer 12 is also disposed in the electrical chamber 15, a rotating shaft 23 of the swing driving motor 22 penetrates through the partition 14 to be located in the atomizing chamber 11, a waterproof sealing member 141 is disposed at a matching position of the rotating shaft 23 and the partition 14, and the waterproof sealing member 141 is specifically, such as a waterproof bushing, which can effectively prevent moisture in the atomizing chamber 11 from entering the electrical chamber 15 while ensuring rotation of the rotating shaft 23. By such a design, the partition plate 14 objectively divides the humidifier housing 10 into two completely independent dry areas and wet areas, i.e., the electrical room 15 and the wet area, i.e., the atomization chamber 11, so as to effectively ensure safe and reliable operation of the electrical components, and more importantly, the motor is disposed in the sealed electrical room 15, so as to effectively isolate noise of the motor, and further add sound insulation measures to the wall body of the electrical room 15, such as increasing the thickness of the wall body, and providing a sound insulation and noise reduction layer, so as to further isolate operation noise of the motor. It should be noted that, while the rotary driving motor itself in the humidifier of the prior art is in an open space, the noise of the motor is not isolated, and particularly, the noise of the motor is often high-frequency noise, and even if the measured value is lower than 28 db, the noise is still clearly audible at quiet night.

Referring to fig. 1, the partition 14 has a first area and a second area, wherein the second area is used for arranging the atomizer 12 and accommodating the water body 101, the height of the first area is higher than the maximum water level of the water body 101 in the second area, and the matching position of the rotating shaft 23 of the rotary driving motor 22 and the partition 14 is in the first area, specifically, the partition 14 is a disk plate, the central area of the disk plate protrudes upwards to form the first area, and the lower disk plate, i.e. the edge area, forms the second area, so that on one hand, the length of the rotating shaft 23 is designed to be relatively short while the water mist 100 is in the negative pressure section of the blade, and the operation noise of the air flow driving blade 21 is prevented from being too large due to the excessively long disturbance degree of the process; on the other hand, the assembly position of the rotating shaft 23 and the partition plate 14 can be prevented from being immersed into the water body 101, and the probability of water leakage is reduced.

In some embodiments, the mist outlet channel 13 extends upward along the height direction, specifically vertically upward, or obliquely upward at an angle with the horizontal plane, the top of the mist outlet channel 13 forms a mist outlet 131, and the rotation axis of the airflow driving blade 21 is coaxial with the center line of the mist outlet channel 13, so that large particles separated from the water mist 100 can flow back into the lower atomizing chamber 11 by gravity, and the structural design of the entire humidifier is simplified.

The inventor researches and finds that the air flow driving blade 21 drives the outgoing air flow 100 to have a certain rotation angle, the rotation angle is generated to be approximately consistent with the rotation direction of the air flow driving blade 21, and correspondingly, a plurality of guide vanes 132 are arranged on the inner peripheral wall of the mist outlet 131, the guide vanes 132 are arranged at intervals along the circumferential direction of the mist outlet 131, and the guide direction of the guide vanes 132 is consistent with the rotation direction of the air flow driving blade 21. By such design, not only the wind (mist) is dispersed, but also the large particle water drops in the rotating airflow from the rotating airflow driving blade 21 are further separated due to centrifugal effect.

In a preferred embodiment, the bottom of the mist outlet channel 13 is provided with a water deflector 133, the water deflector 133 extends away from the mist outlet channel 13, i.e. towards the side of the water body 101, and the water deflector 133 is located between the airflow driving blade 21 and the atomizer 12, and the water deflector 133 is provided with through-flow holes (not shown), it can be understood that the mist 100 will partially collide with the water deflector 133, and this collision process can also reduce the large particle water droplet ratio of the mist 100. The water blocking member 133 is located between the airflow driving blade 21 and the atomizer 12, and can block the water column (generally 2-7 cm in height) generated by the atomizing surface 200 of the ultrasonic vibrator of the atomizer 12 and only allow the water mist 100 to enter the mist outlet channel 13 through the through hole, so that the proportion of large particles contained in the water mist 100 is reduced. Further, when the atomizing humidifier is in operation, the end of the water baffle 133 is located below the liquid surface of the water 101 in the atomizing chamber 11, so that large water droplets separated from the water mist 100 can be directly guided into the water 101 below, and the dripping noise caused by dripping above the liquid surface of the water 101 is prevented, which is often a noise that is hard to endure at a quiet night.

In a specific embodiment, the water blocking member 133 is a sleeve structure in a shape of a truncated cone, the atomizer 12 has a plurality of atomizers 12, the plurality of atomizers 12 are spaced around the water blocking member 133, and the water mist 100 generated by the atomization of each atomizer 12 enters the mist outlet channel 13 through the through holes on the water blocking member 133 and then flows out of the humidifier, so that the mist outlet humidifying effect is better.

In another possible embodiment, referring to fig. 2, the atomizing humidifier further includes a water tub 3 and a water pumping assembly, the water tub 3 has a tub opening, the bottom of the humidifier housing 10 is detachably connected to the tub opening, the water pumping assembly can pump the water 101 in the water tub 3 into the atomizing chamber 11 to ensure that the liquid level of the water 101 in the atomizing chamber 11 is maintained at a preset liquid level, the water tub 3 can specifically adopt a pure water tub on the existing market, in the technical scheme, the pure water in the water tub 3 is directly pumped into the atomizing chamber 11 by the water pumping assembly to be atomized, the water level in the atomizing chamber 11 can be ensured to be stable and the water quantity is sufficient, manual water injection is not needed, and meanwhile, the atomizing humidifier of the present invention does not need to separately provide the water tub 3, which reduces the overall manufacturing and purchasing costs of the humidifier. The water pumping assembly specifically comprises a water pump 41 which is arranged in the electric chamber 15 and controlled by the control panel 5, an inlet of the water pump 41 is connected with a water suction pipe 42, an outlet of the water pump is connected with a water outlet pipe 43, the water suction pipe 42 extends below the liquid level of the water barrel 3, and the water outlet pipe 43 extends into the atomizing chamber 11. Specifically, the humidifier housing 10 has a sleeve 16 which can be fitted over the opening of the water tub 3, and it can be understood that the structures of the sleeve 16 and the opening should be designed to match, so as to ensure that the humidifier housing 10 and the various components therein can be stably and reliably located over the water tub 3. In a specific embodiment, the purified water barrel has large capacity (18L), and one barrel of purified water can be used for 60 hours according to the water consumption of 300ml per hour of a common humidifier, so that the trouble of adding water for multiple times is avoided.
