[0002] Evaporative humidifiers are used to increase the humidity in the air and improve the air quality. At present, the structure of evaporative humidifiers mainly consists of a water tank, a wet curtain assembly and an air supply assembly.

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation manner are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0024] The utility model provides an evaporative humidifier with two wind wheels 221, which increases the air output and improves the air humidification rate by means of two horizontally placed wind wheels 221. At the same time, the two wind wheels 221 are driven simultaneously by a double-headed motor 222, and the volume of the humidifier will not be increased while ensuring the humidification efficiency.

[0025] like Figure 1-6As shown, the embodiment of the utility model provides an evaporative humidifier with double impellers 221, including a water tank 100, a wet curtain 102 that is prevented from being inside the water tank 100, and an air supply assembly 200 that covers the opening of the water tank 100. When the air supply assembly 200 is working, it can stir the air, so that the airflow can pass through the wet curtain 102, thereby cooling and humidifying the airflow. Among them, an air inlet 101 is opened on the side wall of the water tank 100, and the wet curtain 102 is immersed in the water tank 100, so as to ensure that the wet curtain 102 is full of water. The wet curtain 102 is an annular structure, and the wet curtain 102 has a port 103 facing upwards; the air supply assembly 200 is also clamped on the water tank 100, and the air supply assembly 200 includes a housing 210 and a fan assembly 220, wherein the housing 210 is clamped at the opening of the water tank 100, The housing 210 is provided with a housing space 211 inside, and has an air inlet 212 at the lower end that penetrates into the port 103 of the wet curtain 102, the air inlet 212 is connected to the housing space 211, and an air outlet 213 for humidified air to flow out is provided at the upper end of the housing 210; the fan assembly 220 is fixedly installed in the housing space 211, and includes two coaxially arranged wind wheels 221 and a double-headed motor 222 that drives the two wind wheels 221 to rotate simultaneously. In this embodiment, ventilation grilles are provided on the air inlet 212 and the air outlet 213, which can increase the strength of the air outlet 213 and the air inlet 212, and can also play a protective role.

[0026] When humidifying the air, the double-headed motor 222 simultaneously drives the two coaxially arranged wind wheels 221 to rotate. Since the air suction port 212 extends into the port 103 of the wet curtain 102, air can be drawn inside the wet curtain 102. Under the action of air pressure, the air outside the water tank 100 enters along the air inlet 101 and passes through the wet curtain 102, thereby cooling and humidifying the air. When the air is discharged along the air outlet 213, it is used to cool the external space and improve the air.

[0027] The dual-impedance 221 evaporative humidifier provided by the embodiment of the utility model can improve the efficiency of air improvement. Since the two fans are driven to rotate at the same time by the double-headed motor 222 and the two fans are coaxially arranged, the fan assembly 220 is a horizontally placed long strip structure. After being assembled with the water tank 100, the horizontally placed fan assembly 220 can reduce the height of the humidifier and optimize the structure and volume of the humidifier.

[0028] In this embodiment, if Figure 4-5As shown, the fan assembly 220 also includes a mounting shell 223, and a mounting cavity 224 is opened inside the mounting shell 223 and runs through the length direction of the mounting shell 223, and both ends of the mounting cavity 224 are open structures, and the two wind wheels 221 are respectively arranged at both ends of the mounting cavity 224, and the double-headed motor 222 is fixedly installed in the mounting cavity 224 and is transmission-connected to the two wind wheels 221. The outer wall of the mounting shell 223 is also provided with an exhaust port 225 corresponding to the wind wheel 221, and the exhaust port 225 allows the circumferential surface of the wind wheel 221 to leak out, so as to discharge the airflow generated by the rotation of the wind wheel 221. When the motor 222 drives the two wind wheels 221 to rotate, the air is drawn in by the wind wheels 221 at both ends of the installation cavity 224 and then discharged along the exhaust port 225. The exhaust port 225 is set on the outer wall of the installation shell 223, that is, on the side of the installation shell 223, so that the humidified air can be discharged toward the outlet 213 of the casing 210, thereby realizing rapid air discharge.

[0029] In this embodiment, the wind wheel 221 includes a hub 226 that is drivingly connected to the output shaft of the double-headed motor 222. A plurality of blades 227 are formed on both sides of the hub 226. The blades 227 are in a long strip structure and have an arc-shaped cross-section. The blades 227 are arranged at equal intervals along the circumference of the hub 226, and an air duct 228 is defined between two adjacent blades 227. A rim 229 is also provided on the wind wheel 221. The rim 229 is connected to a point on the blade 227 that is away from the hub 226, and the rim 229 is coaxially arranged with the hub 226. Blades 227 are provided on both sides of the hub 226 to increase the exhaust volume of the wind wheel 221 when it rotates. When the wind wheel 221 rotates, the arc-shaped blades 227 stir the air to make it rotate inside the wind wheel 221, and under the use of centrifugal force, the air flows out quickly along the air duct 228 formed between two adjacent blades 227. At this time, the air flow is thrown out along the radial direction of the wind wheel 221, that is, toward the inner wall of the installation cavity 224. The air outlet is provided on the outer wall of the installation shell 223, so that the air thrown out due to the centrifugal force can be discharged.

[0030] In this embodiment, a hollow portion 214 is further provided on the outer wall of the mounting shell 223, and the hollow portion 214 is located at the connection position between the double-headed motor 222 and the wind wheel 221. When the wind wheel 221 rotates, the hollow portion 214 can increase the path of air being stirred by the wind wheel 221, and in particular, can facilitate the hub 226 to draw air toward the blades 227 on the double-headed motor 222 side, thereby increasing the speed of the air fluid.

[0031] The embodiment of the utility model provides an evaporative humidifier with a double wind wheel 221, in which an air supply assembly 200 is arranged on a water tank 100, and the wind wheel 221 and the motor 222 are arranged horizontally, so that the air supply assembly 200 is a horizontal structure. This structure can reduce the height size of the humidifier. More importantly, through the double-headed motor 222, the two wind wheels 221 can be driven to rotate at the same time, thereby increasing the air flow rate and improving the air improvement efficiency.
