Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliances, and in particular to a dual-energy-concentrating humidifier. Background Technology
[0002] The main reason why ultrasonic humidifiers are difficult to top-fill with water is that the ultrasonic energy emitted by the ultrasonic atomizer is limited. If the water level is far from the ultrasonic atomizer, the ultrasonic energy attenuates to the point that it cannot produce water mist when it reaches the water surface. To address this, humidifiers with a focusing float have been developed on the market. This float can concentrate the ultrasonic energy. Propelled by the ultrasonic energy, the focusing float rises to near the water surface. At this point, the dispersed ultrasonic energy emitted by the ultrasonic atomizer is focused by the focusing float to the water surface, allowing for stable water mist production even at high water levels.
[0003] Although adding a humidifier with a concentrating float can solve the technical problem of mist output at high water levels, the ultrasonic energy of the ultrasonic atomizer still attenuates considerably during its propagation to the concentrating float, resulting in a relatively low mist output at high water levels, which is insufficient to meet user needs. Utility Model Content
[0004] The present invention aims to provide a dual-energy-concentrating humidifier to increase the amount of water mist generated at high water levels.
[0005] The dual-energy-concentrating humidifier according to a first aspect embodiment of the present invention includes:
[0006] The lower housing is equipped with an ultrasonic atomizer;
[0007] The upper housing is sealed to the upper side of the lower housing. The upper housing has a water storage chamber inside. The top surface of the upper housing is a water inlet. The bottom surface of the upper housing has a bottom hole facing the ultrasonic atomizer.
[0008] A top cover covers the water inlet. The top cover has a downwardly extending mist guide tube. The bottom and top of the mist guide tube are respectively provided with a sound wave port and a mist outlet. The sound wave port and the mist outlet are both directly opposite the ultrasonic atomizer. The mist guide tube is provided with an energy-concentrating movable ring. The energy-concentrating movable ring slides along the length of the mist guide tube and is limited. The energy-concentrating movable ring has a first energy-concentrating hole directly opposite the ultrasonic atomizer and the mist outlet.
[0009] A concentrating ring is defined between the ultrasonic atomizer and the mist guide tube, and the concentrating ring is provided with a second concentrating hole facing the ultrasonic atomizer and the acoustic port.
[0010] The dual-energy-concentrating humidifier according to the embodiments of this utility model has at least the following beneficial effects: In addition to the floating energy-concentrating movable ring, this utility model also has an energy-concentrating fixed ring fixed between the ultrasonic atomizer and the energy-concentrating movable ring. The energy-concentrating fixed ring can initially guide the ultrasonic energy generated by the ultrasonic atomizer, so that the ultrasonic energy can propagate towards the upper energy-concentrating movable ring in a shorter path and a more concentrated direction, thereby reducing the loss of ultrasonic energy during propagation, and allowing the energy-concentrating movable ring to propagate more ultrasonic energy to the water surface, thereby increasing the amount of water mist generated at high water levels.
[0011] According to some embodiments of this utility model, the first energy-concentrating hole has a tapered structure that increases from bottom to top. When the mist guide tube is in a water environment, some of the ultrasonic energy can push the energy-concentrating movable ring upwards towards the water surface, causing the energy-concentrating movable ring to vibrate itself. Another portion of the ultrasonic energy couples to the water surface through the first energy-concentrating hole and generates water mist. The tapered structure of the first energy-concentrating hole can better diffuse ultrasonic energy to the water surface, causing vibration over a larger area of the water surface.
[0012] According to some embodiments of this utility model, the second focusing aperture has a tapered structure that increases from bottom to top. The tapered structure of the second focusing aperture reduces energy attenuation during propagation by constraining the lateral divergence of ultrasonic waves. Under the guidance of the second focusing aperture, the ultrasonic waves maintain a more concentrated beam, avoiding energy loss due to diffusion, thereby improving the sound wave transmission efficiency towards the water surface.
[0013] According to some embodiments of this utility model, in order to reduce interference with ultrasonic energy, both the energy-concentrating movable ring and the energy-concentrating fixed ring are plastic components.
[0014] According to some embodiments of this utility model, the upper housing is provided with a surrounding plate at the edge of the bottom hole, and the energy-concentrating fixing ring is snapped into the surrounding plate. The upper housing is provided with a surrounding plate at the edge of the bottom hole, the ultrasonic atomizer is connected below the surrounding plate, and the mist guide tube extends into the surrounding plate. At this time, the energy-concentrating fixing ring is confined between the mist guide tube and the ultrasonic atomizer.
[0015] According to some embodiments of the present invention, the upper housing is provided with a surrounding plate at the edge of the bottom hole, the ultrasonic atomizer is connected below the surrounding plate, and the energy-concentrating fixing ring is snapped into the surrounding plate, thereby defining the position of the energy-concentrating fixing ring.
[0016] According to some embodiments of this utility model, since the ultrasonic energy of the ultrasonic atomizer generates water mist by oscillating the water surface, some liquid will splash out of the mist outlet when the water level is high. In order to prevent liquid from splashing out of the mist outlet to the outside, the mist outlet is equipped with a mist cover. The mist cover is provided with a mist inlet hole and a mist outlet hole, and the positions of the mist inlet hole and the mist outlet hole are staggered vertically.
[0017] According to some embodiments of this utility model, in order to guide the water mist inside the upper housing to be discharged, a fan is installed on the lower housing, the fan has an exhaust port on the lower housing, and an upwardly extending air guide tube is provided on the bottom surface of the upper housing. The bottom and top of the air guide tube are respectively provided with an air inlet and an air outlet. The air inlet is connected to the air outlet, and the air outlet is close to the top cover.
[0018] According to some embodiments of this utility model, since water is added from the top, a cover is installed at the air outlet to prevent liquid from entering the air duct during water addition. The cover has a downward-extending air outlet channel that communicates with the air outlet. It should be noted that the highest water level in the upper casing must not exceed the height of the air outlet channel to prevent liquid from entering the air duct and damaging the fan.
[0019] According to some embodiments of this utility model, the side wall of the mist guide tube is provided with a wind groove arranged in the vertical direction. The maximum height of the wind groove is not lower than the height of the air outlet, so as to guide the flowing gas in the upper shell into the mist guide tube, thereby driving the water mist to be discharged outward.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0032] like Figures 1 to 4As shown, the dual-energy humidifier according to a first aspect embodiment of the present invention includes a lower housing 100 and an upper housing 200. The lower housing 100 is equipped with an ultrasonic atomizer 300 and a fan 400. The fan 400 has an exhaust port 410 on the lower housing 100. Since the ultrasonic atomizer 300 and the fan 400 are existing technologies, their specific structures are not described in detail in this invention. To control the ultrasonic atomizer 300 and the fan 400, a controller 120 is built into the lower housing 100. Both the ultrasonic atomizer 300 and the fan 400 are controlled by the controller 120. A control button 110 electrically connected to the controller 120 is provided on the outer wall of the lower housing 100.
[0033] In addition, the upper housing 200 is sealed to the lower housing 100 by screws, and a sealing strip 130 is wrapped around the connection. The upper housing 200 has a water storage chamber 210 inside, the top surface of the upper housing 200 is a water inlet 220, the bottom surface of the upper housing 200 has a bottom hole facing the ultrasonic atomizer 300, and the bottom surface of the upper housing 200 has an upward-extending air guide tube 500. The bottom and top of the air guide tube 500 are respectively provided with an air inlet and an air outlet 520. The air inlet is connected to the exhaust port 410, and the air outlet 520 is close to the water inlet 220. Since this invention uses a top-filling method for water addition, a cover 530 is installed on the air outlet 520 to prevent liquid from entering the air duct 500 during water addition. The cover 530 has a downward-extending air outlet channel 531 that connects to the air outlet 520 to prevent the air outlet channel 531 from being exposed upwards. It should be noted that the highest water level in the upper housing 200 must not exceed the height of the air outlet channel 531 to prevent liquid from flowing back into the air duct 500 and damaging the fan 400.
[0034] like Figure 3 and Figure 4 As shown, to generate water mist within the upper housing 200, the water inlet 220 of the upper housing 200 is covered by a top cover 600. The top cover 600 has a downwardly extending mist guide tube 610 located within the water storage chamber 210 of the upper housing 200. The bottom and top of the mist guide tube 610 are respectively provided with a sonic port 611 and a mist outlet 612, both of which are directly opposite the ultrasonic atomizer 300. A concentrating ring 700 is provided inside the mist guide tube 610. The outer diameter of the concentrating ring 700 is slightly larger than the inner diameter of the mist guide tube 610, allowing the concentrating ring 700 to slide along the length of the mist guide tube 610. The concentrating ring 700 has a first concentrating hole 710 directly opposite the ultrasonic atomizer 300 and the mist outlet 612.
[0035] In addition, the upper housing 200 has a surrounding plate 231 at the edge of the bottom hole. The surrounding plate 231 extends along the upper and lower directions of the bottom hole respectively. The lower part of the surrounding plate 231 is connected to the ultrasonic atomizer 300. An energy-concentrating fixing ring 800 is placed inside the surrounding plate 231. The energy-concentrating fixing ring 800 is a ring-shaped body with a certain height. The energy-concentrating fixing ring 800 is limited between the ultrasonic atomizer 300 and the mist guide tube 610. The energy-concentrating fixing ring 800 has a second energy-concentrating hole 810 facing the ultrasonic atomizer 300 and the sound wave port 611.
[0036] In addition to the energy-concentrating movable ring 700, this invention also includes an energy-concentrating fixed ring 800 between the ultrasonic atomizer 300 and the energy-concentrating movable ring 700. The energy-concentrating fixed ring 800 provides initial guidance for the ultrasonic energy generated by the ultrasonic atomizer 300, allowing it to propagate upwards towards the energy-concentrating movable ring 700 via a shorter path and in a more concentrated direction. This reduces energy loss during propagation, enabling the energy-concentrating movable ring 700 to transmit more ultrasonic energy towards the water surface, thereby increasing the amount of water mist generated at high water levels. It should be further noted that, to minimize interference with the ultrasonic energy, both the energy-concentrating movable ring 700 and the energy-concentrating fixed ring 800 are made of plastic to approximate the acoustic impedance of ultrasound in water, effectively reducing ultrasonic reflection loss and improving energy transfer efficiency.
[0037] In some embodiments of this utility model, in order to limit the position of the energy-concentrating fixing ring 800, the mist guide tube 610 extends downward into the enclosure 231, so that the energy-concentrating fixing ring 800 cannot leave the enclosure 231. Alternatively, the outer dimension of the energy-concentrating fixing ring 800 is slightly larger than the inner dimension formed by the enclosure 231, so that the energy-concentrating fixing ring 800 can be engaged within the enclosure 231.
[0038] like Figure 5 As shown, the first focusing aperture 710 has a tapered structure that increases from bottom to top. When the mist guide 610 is in a water environment, some of the ultrasonic energy can push the focusing ring 700 upwards towards the water surface, causing the focusing ring to vibrate. The remaining ultrasonic energy is coupled to the water surface through the first focusing aperture 710 and generates water mist. The tapered structure of the first focusing aperture 710 can better diffuse ultrasonic energy to the water surface, causing vibration over a larger area of the water surface.
[0039] Meanwhile, the second focusing aperture 810 has a tapered structure that increases from bottom to top. The tapered structure of the second focusing aperture 810 reduces the energy attenuation during propagation by constraining the lateral divergence of the ultrasonic wave. Under the guidance of the second focusing aperture 810, the ultrasonic wave maintains a more concentrated beam, avoiding energy loss due to diffusion, thereby improving the transmission efficiency of sound waves towards the water surface.
[0040] The shape of the focusing aperture can act as an acoustic waveguide, altering the direction of ultrasonic wave propagation through geometric structure and focusing the originally dispersed ultrasonic energy onto a specific area of the water surface. The relative position of the focusing movable ring 700 on the water surface can create standing wave conditions, generating amplitude superposition at a specific water depth, increasing local energy density, and promoting atomization. Experiments have shown that adding an additional focusing fixed ring 800 to the focusing movable ring 700 can effectively increase the amount of water mist generated at high water levels, with an increase of up to 30%.
[0041] like Figure 3 As shown, in some embodiments of this utility model, since the ultrasonic energy of the ultrasonic atomizer 300 generates water mist by oscillating the water surface, some liquid will splash outside the mist outlet 612 when the water level is high. In order to prevent liquid from splashing to the outside from the mist outlet 612, a mist cover 900 is installed on the mist outlet 612. The mist cover 900 is provided with a mist inlet hole 910 and a mist outlet hole 920. The positions of the mist inlet hole 910 and the mist outlet hole 920 are staggered vertically, so that the liquid splashed from the water surface cannot directly reach the mist outlet hole 920 through the mist inlet hole 910.
[0042] In some embodiments of this utility model, the side wall of the mist guide cylinder 610 is provided with a wind groove 613 arranged in the vertical direction. The maximum height of the wind groove 613 is not lower than the height of the air outlet 520, so as to guide the flowing gas in the upper housing 200 into the mist guide cylinder 610, thereby driving the water mist to be discharged outward.
[0043] like Figure 4 As shown, in some embodiments of this utility model, in order to increase the wind speed, the cross-sectional area of the air duct 500 decreases sequentially from bottom to top. When it is necessary to add water to the humidifier, the top cover 600 can be removed first. At this time, the water inlet 220 of the upper shell 200 is exposed. The user can pour water directly from the water inlet 220 into the water storage chamber 210, but the water level in the water storage chamber 210 must not exceed the warning level. After adding water, the top cover 600 is replaced, thus completing the water filling process of the dual-energy humidifier.
[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
