[0018] The present invention is not limited to the embodiments disclosed below and can be implemented by combining the disclosed embodiments. The following will be described with reference to the drawings.

[0019] Figure 1 is a perspective view illustrating an ultrasonic humidifier according to an embodiment.

[0020] As Figure 1 shown, the ultrasonic humidifier 1 may include a water tank 10, a water tank cover 20, a base 30, a drain port 50, and a handle 40.

[0021] The water tank 10 is a container capable of storing water inside.

[0022] The water tank 10 can be made of a metallic material such as stainless steel. For example, the water tank 10 can be made of 304 stainless steel, 316 stainless steel, and antibacterial stainless steel with added copper to enhance antibacterial properties. Additionally, the water tank 10 can be manufactured using synthetic chemicals such as ABS and combining it with a metallic material.

[0023] The water tank lid 20 is an object that covers the water tank to prevent foreign objects from entering the water tank 10 from the outside. The water tank lid 20 can be made of a metallic material such as stainless steel. For example, the water tank lid 20 can be made of 304 stainless steel, 316 stainless steel, and antibacterial stainless steel with enhanced antibacterial properties by adding copper. Additionally, the water tank lid 20 can be manufactured using synthetic chemicals such as ABS and combining it with a metallic material. For example, the outer side of the water tank lid 20 can be made of ABS, and the inner side can be made of antibacterial stainless steel.

[0024] According to one embodiment, the water tank lid 20 can be connected to the water tank 10 by a hinge. According to another embodiment, the water tank lid 20 has a circular structure and can rotate on the top of the water tank 10. Additionally, the water tank lid 20 can be rotatably connected to the water tank 10 using threads.

[0025] The discharge port 50 is an opening for discharging the atomized water molecules in the water tank 10 to the outside of the ultrasonic humidifier 1. According to one embodiment, the discharge port 50 has a structure in which a part of the upper end of the water tank protrudes to the outside. According to another embodiment, the discharge port 50 is formed by opening a part of the water tank lid.

[0026] The base 30 is a device for supplying power to the ultrasonic humidifier 1 and controlling its operation. The base 30 can be located below the water tank 10.

[0027] According to one embodiment, the base 30 can include a user input unit that receives a user's input and controls at least one of the functions of the power supply and the spray amount of the ultrasonic humidifier 1.

[0028] According to one embodiment, the exterior of the base 30 includes a lamp (e.g., multiple LED point light sources, etc.) for displaying at least one of the functions of the water volume and the spray amount.

[0029] According to one embodiment, the base 30 includes a blower that inhales air from the outside and a control circuit. The control circuit delivers the power input from the outside to the ultrasonic vibration unit and the blower, and controls the operations of the ultrasonic vibration unit and the blower. The base 30 includes an intake vent and an exhaust vent. There is an intake vent at least at one of the bottom surface and the side surface of the base 30. There is an exhaust vent on the side surface of the base 30.

[0030] The control circuit can supply voltage and current to the internal components of the ultrasonic humidifier 1 according to an externally input power source. The control circuit adjusts the spray amount by changing the driving intensity of the ultrasonic vibration unit according to the user's input. The control circuit can control the lamp to display the spray amount and the water shortage notification. For example, the control circuit can turn on / off each of a plurality of point light sources to display the spray amount using the number of turned-on point light sources. The control circuit can control the plurality of point light sources to flash to display the water shortage notification.

[0031] The blower is a device that generates wind to discharge the water molecules generated in the water tank (10) to the outside. The blower can be located near the intake vent of the base 30. For example, the blower can be located at the top of the vent below the base 30. The blower can be located near the exhaust vent of the base 30. For example, the blower can be located near the exhaust vent on one side of the base 30.

[0032] The handle 40 is a device mounted on the ultrasonic humidifier 1 to facilitate the user to hold the ultrasonic humidifier 1. One side of the handle 40 is connected to the base 30, and the other side is connected to the water tank 10.

The handle 40 includes a pipeline that conveys the air discharged from the base 30 to the water tank 10.

[0033] Figure 2 It is a diagram showing the water tank of an embodiment of the ultrasonic humidifier.

[0034] As Figure 2 shown, the water tank 10 can be composed of a bottom surface 11 and a wall 13.

[0035] The water tank 10 has an ultrasonic vibration unit 12 located on the bottom surface. The ultrasonic vibration unit 12 applies ultrasonic vibration to the water in the water tank to form a misty water mist.

[0036] The ultrasonic vibration unit 12 is a device that generates ultrasonic vibration. The ultrasonic vibration unit 12 can include a vibrating plate and a vibrator. For example, one side of the ultrasonic vibration unit 12 has a vibrating plate made of a metal material, and the other side has a vibrator made of a piezoelectric ceramic material or the like. When current is applied to the vibrator, the size of the vibrator changes according to the frequency, and the vibrating plate mounted on the vibrator performs ultrasonic vibration. According to the vibration of the vibrating plate, the water at the top of the ultrasonic vibration unit starts to atomize. One side of the vibrator of the ultrasonic vibration unit 12 has a corrosion-resistant metal sheet to prevent the vibrator from being scratched or damaged. There is a water level detection sensor below the ultrasonic vibration unit. The water level detection sensor can identify the drop in the water level above the ultrasonic vibration unit 12 and generate a notification signal, which is sent to the control circuit.

[0037] There is a protrusion 14 on the wall 13 of the water tank 10. The protrusion 14 is a part of the wall 13 of the water tank 10 that protrudes into the interior of the water tank 10.

[0038] According to one embodiment, the center of the protrusion 14 is recessed towards the interior of the water tank. The protrusion 14 has a non-angled bending structure, so that the water droplets splashed on the ultrasonic vibrator 12 naturally flow into the water tank 10.

[0039] There is an ultrasonic vibration unit 12 on the bottom surface 11 of the water tank 10. According to one embodiment, the ultrasonic vibration unit 12 is around the protrusion 14. The ultrasonic vibration unit 12 is inclined at a specified angle such that the vibration plate faces the protrusion. For example, the vibration plate can be inclined towards the protrusion at an inclination of 5 to 10 degrees. The ultrasonic vibration unit 12 includes a support surface that is inclined towards the protrusion, and there is a vibrator and a vibration plate above the support surface and it is inclined towards the protrusion.

[0040] According to one embodiment, the bottom surface 11 of the water tank 10 has an inclined structure such that water collects in the ultrasonic vibration unit 12. For example, since the bottom surface of the water tank 10 near the ultrasonic vibration unit is lower than the bottom surface near the water tank wall, the end is a conical structure like a funnel.

[0041] According to a disclosed embodiment, due to the inclination of the protrusion 14 of the water tank 10 and the vibration plate of the ultrasonic vibrator 12, the dripping noise generated by the splashing of the ultrasonic vibrator 12 can be reduced.

[0042] Figure 3 It is a diagram showing the protrusion of an ultrasonic humidifier according to one embodiment.

[0043] According to one embodiment, the protrusion 14 is composed of a plurality of concave-convex structures. The protrusion 14 has a step connecting the plurality of concave-convex structures. For example, among the plurality of concave-convex structures, the first concave-convex structure is above the protrusion 14, the second concave-convex structure is at the center of the protrusion 14, and the third concave-convex structure is below the protrusion 14. The first height of the first concave-convex structure is the lowest among the second height of the second concave-convex structure and the third height of the third concave-convex structure, and the third height of the third concave-convex structure can be the highest.

[0044] According to one embodiment, the plurality of concave-convex structures extend along the height direction of the wall 13 of the water tank 10 to form a curved structure like a wave. That is, the plurality of concave-convex structures can be connected in a curve such that no angle is generated between the concave-convex structures.

[0045] According to a disclosed embodiment, the plurality of concave-convex structures can reduce the dripping noise generated by the water flowing along the wall 13 of the water tank 10.

[0046] Figure 4It is a diagram showing the water tank cover of an ultrasonic humidifier according to an embodiment.

[0047] As Figure 4 shown, the water tank cover 20 has a structure that is concave from the bottom to the top. That is, a slope is formed from the central part 21 to the edge part 22, such that the central part 21 at the bottom of the water tank cover 20 is thinner than the edge part 22.

[0048] According to an embodiment, the slope of the edge part 22 of the water tank cover 20 is steeper than the slope between the central part 21 and the edge part 22. That is to say, the first slope of the water tank cover 20 between the central part 21 and the first distance is gentler than the second slope between the first distance and the second distance.

[0049] According to a disclosed embodiment, the water splashed by the ultrasonic vibrator descends along the surface of the water tank cover 20 through the slope of the water tank cover 20 near the water tank protrusion, thereby reducing the noise of dripping water.

[0050] Figure 5 It is a diagram showing the air supply direction of an ultrasonic humidifier according to an embodiment.

[0051] As Figure 5 shown, the base 30 includes an intake vent and an exhaust vent. According to an embodiment, there is an intake vent at at least one of the bottom surface and the side surface of the base 30. According to an embodiment, there is an exhaust vent on the side surface of the base 30.

[0052] The base 30 can inhale external air through the blower 31 and discharge it through the pipeline 45 inside the handle 40. The air inside the pipeline 45 is delivered to the intake vent of the water tank 10. The air entering the water tank 10 can be discharged together with the water molecules inside the water tank 10 through the discharge port 50.

[0053] Figure 6 It is a diagram showing the handle of an ultrasonic humidifier according to an embodiment.

[0054] As Figure 6 shown, the handle 40 includes an inner part 41 and an outer part 42. By combining the inner part 41 and the outer part 42, a pipeline 45 can be formed inside the handle 40.

[0055] According to an embodiment, the central parts of the inner part 41 and the outer part 42 are thinner than the two sides. Through the inner part 41 and the outer part 42 whose central parts are thinner than the two sides, a pipeline 45 can be formed longitudinally inside the handle 40.

[0056] According to one embodiment, the inner part 41 and the outer part 42 can be magnetically connected. For example, the inner part 41 and the outer part 42 include magnets with different magnetisms and are magnetically connected. Another example is that one of the inner part 41 and the outer part 42 includes a magnet, and the other includes a material (such as an iron plate, etc.) connected to the magnet, so as to be magnetically connected.

[0057] According to one embodiment, the inner part 41 may include a bag 43. For example, a part of the inner part 41 extends towards the ground direction to form the bag 43. The bag 43 can be located at the top of the inner part 41. The bag 43 can be located near the water tank wall. The bag 43 temporarily stores the water that enters through the vent on the water tank wall, thereby preventing the water from flowing into the blower.

[0058] Figure 7 It is a diagram showing a water purification unit of an ultrasonic humidifier according to one embodiment. The water purification unit 60 is a device that removes and discharges foreign matters from the water flowing in from the outside. The water purification unit 60 is connected to the top of the water tank 10. For example, a part of the frame 62 enters the inside of the water tank 10.

[0059] As Figure 7 shown, the water purification unit 60 includes a frame 62, a water purification filter 63, and a water purification cover 61.

[0060] There is a water purification filter 63 inside the frame 62, which is a device that temporarily receives the water flowing in from the outside. The frame 62 can open at least a part of the top and has a water outlet part in the lower area. The frame 62 includes a gripping part 64 extending outwardly on one side of the upper end. There are scales on the frame 62 to identify the amount of water introduced therein. The scale values inside the frame 62 are the same as the scale values shown on the inner wall of the water tank 10. The outer diameter of the frame 62 is consistent with the inner diameter of the water tank 10, so that at least a part of the frame 62 can be located inside the water tank 10.

[0061] The water purification cover 61 is an object that covers the frame 62 to prevent foreign matters from entering the water purification unit 60 from the outside. The outer diameter of the water purification cover 61 can be larger than the outer diameter of the frame 62. After the water flowing into the frame 62 of the water purification cover 61 is discharged into the water tank 10 through the water purification filter 63, it can support the frame 62 separated from the water tank 10 as a bracket. The user can place the frame 62 on it by flipping the water purification cover 61 to prevent the inconvenience caused by the residual water in the frame from flowing out. There are a plurality of wavy patterns arranged at regular intervals on the bottom surface of the water purification cover 61. The plurality of wavy patterns can accelerate the drying of the inside of the water purification filter 63.

[0062] The water purification filter 63 is located inside the frame 62 and can remove foreign matters in the water flowing into the frame 62. The water purification filter 63 includes an upper filter unit 65, a lower filter unit 66, and a filtering filler material.

[0063] The upper filter unit 65 is closely attached to the top of the lower filter unit 66. The upper filter unit 65 includes a plurality of inlets 67 uniformly arranged along its circumference.

[0064] The lower filter unit 66 is internally provided with filter filling materials. There are mesh structures at the bottom of the upper filter unit 65 and the top of the lower filter unit 66. The filter filling materials can be located between the mesh structure of the upper filter unit 65 and the mesh structure of the lower filter unit 66.

[0065] The filter filling materials can remove foreign matters in the water flowing in through the inlets 67 of the top filter unit 65. The filter filling materials can include ion exchange resins, activated carbon, HEPA filters or ceramic filter plates, and these materials can effectively remove scale and calcium and magnesium ions in the water.

[0066] The lower filter unit 66 includes a water outlet 68 and a protrusion 69. Among them, the water outlet 68 can discharge purified water, while the protrusion 69 can prevent unpurified water from being discharged. The water outlet 68 is located near the water outlet of the frame 62. The protrusion 69 is around the water outlet 68 of the lower filter unit 66.

[0067] The user can install the frame 62 with the water purification filter 63 on the top of the water tank 10 and inject water into the marked position on the frame 62. The user can drain the injected water into the frame 62 in the water tank 10, separate it from the water tank 10, and place it above the flipped water purification cover 61. The user can cover the water tank cover 20 on the top of the water tank 10 filled with water and operate the ultrasonic humidifier 1 through the user input unit located on the base 30.

[0068] According to an embodiment disclosed, the ultrasonic humidifier 1 can use the purified water for humidification through the water purification unit 60, thereby discharging water molecules without limestone, calcium and magnesium ions.
