Description

雾化装置及超声波加湿器 技术领域  Atomizing device and ultrasonic humidifier
本发明涉及一种雾化装置， 尤其是涉及一种用于液体雾化的雾化装置及 超声波加湿器。 背景技术  The present invention relates to an atomizing device, and more particularly to an atomizing device for liquid atomization and an ultrasonic humidifier. Background technique
现有的液体雾化的方法之一就是釆用超声雾化方案， 通过超声雾化器对 液体（如水、 药剂、 香剂） 予以雾化。 超声波加湿器就是釆用超声雾化方案 的应用之一。  One of the existing methods of liquid atomization is to use an ultrasonic atomization scheme to atomize liquids (such as water, chemicals, and fragrances). An ultrasonic humidifier is one of the applications of the ultrasonic atomization scheme.
传统的超声波加湿器包括机座和水箱组件， 水箱组件连接在机座的上方， 所述机座上安装有雾化装置， 雾化装置具有换能器 （又叫雾化片或压电陶瓷 片）。 当水箱组件中加入足够的水后， 借助水箱组件的底部结构 （水阀）来控 制水从水箱底部流入机座内并覆盖换能器， 换能器将机座中的水进行高频振 荡使其雾化。 水箱组件必须具备足够的密封性来隔绝水箱组件中的水与外界 空气接触， 才能通过水箱组件的底部结构控制流入机座内的水量， 从而保证 覆盖在换能器上的水位具有固定高度时产生水雾。 因此， 现有的超声波加湿 器存在如下缺陷： 由于需要借助水箱组件的底部结构来控制水从水箱底部流 入机座， 水箱组件的结构复杂且要求具有较高的密封性， 从而导致制造工艺 复杂、 加工制造成本较高、 可靠性较差且雾化效率较低。  The conventional ultrasonic humidifier includes a base and a water tank assembly. The water tank assembly is connected above the base. The base is equipped with an atomizing device. The atomizing device has a transducer (also called an atomizing piece or a piezoelectric ceramic piece). ). After adding enough water to the tank assembly, the bottom structure (water valve) of the tank assembly controls the flow of water from the bottom of the tank into the base and covers the transducer. The transducer oscillates the water in the base. It is atomized. The water tank assembly must have sufficient sealing to insulate the water in the water tank assembly from the outside air in order to control the amount of water flowing into the frame through the bottom structure of the water tank assembly, thereby ensuring that the water level covering the transducer has a fixed height. Water mist. Therefore, the existing ultrasonic humidifier has the following drawbacks: Since the bottom structure of the water tank assembly is required to control the flow of water from the bottom of the water tank to the base, the structure of the water tank assembly is complicated and requires a high sealing property, thereby resulting in a complicated manufacturing process. The manufacturing cost is high, the reliability is poor, and the atomization efficiency is low.
另外， 为了提高雾化效率， 某些厂家对现有的超声波加湿器进行改进， 在换能器上方增加聚能罩。 比如， 申请号 201010124717.9的中国专利申请， 公开了一种用于雾化装置的聚能罩， 聚能罩直接压紧在换能器上， 而聚能罩 的下部设置二个进水孔， 所述聚能罩旋合在雾化器的壳体上。 该结构的聚能 罩虽然能够在一定程度上提高雾化效率， 但仍存在如下缺陷： 1、 该专利申请仍需要借助水箱组件的底部结构来控制水从水箱底部流入 机座， 确保覆盖在换能器上的水位具有固定高度时聚能罩发挥聚集水雾的效 果， 因此并未改变传统的超声波加湿器中水箱组件的结构， 仍存在水箱组件 结构复杂且要求具有较高的密封性而导致制造工艺复杂、 加工制造成本较高、 可靠性较差且雾化效率较低（经实验证明， 其雾化效率的提升空间也仅仅只 是在大约 5 %到 8 %之间， 故雾化效率的提升效果不明显）。 In addition, in order to improve the atomization efficiency, some manufacturers have improved the existing ultrasonic humidifier by adding a collecting cover above the transducer. For example, Chinese Patent Application No. 201010124717.9 discloses a collecting cover for an atomizing device, the collecting cover is directly pressed against the transducer, and the lower portion of the collecting cover is provided with two inlet holes. The concentrating cover is screwed onto the housing of the atomizer. Although the energy collecting cover of the structure can improve the atomization efficiency to a certain extent, the following defects still exist: 1. The patent application still needs to use the bottom structure of the water tank assembly to control the flow of water from the bottom of the water tank to the base, ensuring that the energy cover covering the water level of the transducer has a fixed height, and the energy collecting cover exerts the effect of collecting water mist, so it has not changed. The structure of the water tank assembly in the conventional ultrasonic humidifier still has a complicated structure of the water tank assembly and requires high sealing performance, resulting in complicated manufacturing process, high processing and manufacturing cost, poor reliability, and low atomization efficiency. It proves that the space for improving the atomization efficiency is only about 5% to 8%, so the effect of improving the atomization efficiency is not obvious.
2、由于聚能罩是固定的，需要由水箱组件配合控制流到换能器上的水量， 才能保证聚能罩发挥聚集水雾的效果。 若从水箱组件流到换能器上的水量过 多， 甚至水位没过聚能罩的顶部时， 聚能罩对提高雾化量的改善效果不明显， 因此， 现有的聚能罩不仅适应性较差， 且雾化增强效果也不甚理想。  2. Since the energy collecting cover is fixed, it is necessary to control the amount of water flowing to the transducer by the water tank assembly to ensure that the energy collecting cover exerts the effect of collecting water mist. If the amount of water flowing from the water tank assembly to the transducer is too large, even if the water level does not pass over the top of the energy collecting cover, the effect of the energy collecting cover on improving the atomization amount is not obvious, and therefore, the existing energy collecting cover not only adapts The performance is poor, and the atomization enhancement effect is not satisfactory.
3、 由于聚能罩固定在雾化器的壳体上， 不仅安装不便， 且清洗时需要从 壳体上拆卸聚能罩， 操作繁瑣、 清洗不便。 发明内容  3. Since the energy collecting cover is fixed on the shell of the atomizer, it is not only inconvenient to install, but also needs to remove the energy collecting cover from the housing during cleaning, which is cumbersome to operate and inconvenient to clean.

由于现有超声波加湿器的水箱组件需要具有较好的密封性且具有控制液 体流入机座的底部结构， 而本发明中盛放雾化液体的水箱无需隔绝液体与外 界空气的接触， 可以为敞口容器或具有上盖的容器等。 因此， 本发明的超声 波加湿器可以由结构简单的水箱替代现有超声波加湿器中结构复杂的水箱组 件， 从而至少具有如下优点： A、 由于本发明釆用结构简单的水箱， 从而简化 了超声波加湿器结构， 降低制造工艺难度及制造成本； B、 由于现有技术中水 箱组件的结构复杂性给制造工艺带来诸多限制， 导致用于将水雾导出水箱组 件的导筒只能垂直（与地面垂直）设置在水箱组件中， 水雾沿着垂直设置的 导筒上升时， 由于重力作用而部分飘落在超声波加湿器的四周， 导致加湿效 果较差， 且超声波加湿器四周的水雾又会由超声波加湿器的风扇抽入加湿器 内， 于此长期工作容易使超声波加湿器的机座内的控制电路板受潮而导致失 效、 损坏等， 而本发明釆用结构简单的水箱， 导筒可以任意角度设置， 规避 上述问题， 达到较佳的加湿效果； c、 用户在使用现有的超声波加湿器的过程 中， 常出现用户从出雾口 （导筒的上末端）对现有超声波加湿器加水而造成 故障的现象， 而本发明超声波加湿器可以直接通过水箱的杯口或杯盖加水， 即使用户从出雾口加水， 水也是直接进入了水箱， 与通过水箱的杯口或杯盖 加水具有相同的效果， 不会导致超声波加湿器出现故障， 从而可以提高用户 的操作便利度及提高超声波加湿器的可靠性。 Since the water tank assembly of the existing ultrasonic humidifier needs to have better sealing performance and has a bottom structure for controlling the flow of liquid into the machine base, the water tank for holding the atomized liquid in the present invention can be opened without isolating the contact of the liquid with the outside air. a mouth container or a container having an upper cover or the like. Therefore, the ultrasonic humidifier of the present invention can replace the structurally complicated water tank assembly of the existing ultrasonic humidifier by a water tank having a simple structure, thereby at least having the following advantages: A. Since the present invention uses a water tank having a simple structure, the ultrasonic humidification is simplified. Structure, reduce manufacturing process difficulty and manufacturing cost; B. Due to the structural complexity of the water tank assembly in the prior art, the manufacturing process brings many restrictions, and the guide cylinder for guiding the water mist to the water tank assembly can only be vertical (with the ground) Vertically disposed in the water tank assembly, when the water mist rises along the vertically disposed guide cylinder, it partially falls around the ultrasonic humidifier due to gravity, resulting in humidification The result is poor, and the water mist around the ultrasonic humidifier is pumped into the humidifier by the fan of the ultrasonic humidifier. This long-term work is easy to cause the control circuit board in the frame of the ultrasonic humidifier to be damp, resulting in failure, damage, etc. The invention adopts a water tank with a simple structure, and the guide cylinder can be disposed at an arbitrary angle to avoid the above problems and achieve a better humidification effect; c. The user often uses the existing ultrasonic humidifier to generate fog from the user. The mouth (the upper end of the guide tube) adds water to the existing ultrasonic humidifier to cause a malfunction, and the ultrasonic humidifier of the present invention can directly add water through the cup mouth or the lid of the water tank, even if the user adds water from the mist outlet, the water is directly Entering the water tank has the same effect as adding water through the cup or the lid of the water tank, and does not cause the ultrasonic humidifier to malfunction, thereby improving the user's operation convenience and improving the reliability of the ultrasonic humidifier.
综上， 本发明对现有超声波加湿器进行了革命性的改进， 换能器上方的 液体处于任何液位高度时， 本发明提出的雾化装置或超声波加湿器均能产生 较佳的雾化效果， 从而可以适应任何液位高度的使用环境， 摒弃现有超声波 加湿器中需要借助水箱组件的底部结构来控制换能器上的液位高度， 使雾化 装置具有适应性较佳、 结构简单、 用材较少而制造成本较低、 安装方便、 易 于清洗等优点。 附图说明  In summary, the present invention revolutionizes the existing ultrasonic humidifier. When the liquid above the transducer is at any liquid level, the atomization device or the ultrasonic humidifier proposed by the present invention can produce better atomization. The effect can be adapted to the environment of any liquid level. Abandoning the existing ultrasonic humidifier requires the bottom structure of the water tank assembly to control the liquid level on the transducer, so that the atomizing device has better adaptability and simple structure.

本发明提出一种雾化装置及超声波加湿器， 在换能器上方的液体中漂浮 设置雾化增强部， 使换能器上方的液体处于任何液位高度时均能产生较佳的 雾化效果。 由于本发明在换能器上的液体处于动态变化的任何液位高度时均 能够正常工作， 不再需要借助水箱组件的底部结构来控制换能器上的液位高 度保持固定， 从而可以摆脱超声波加湿器对水箱组件的依赖， 实现简化结构 和提高雾化效果的目的。 The invention provides an atomizing device and an ultrasonic humidifier floating in a liquid above the transducer The atomization enhancement portion is arranged to produce a better atomization effect when the liquid above the transducer is at any liquid level. Since the invention can work normally when the liquid on the transducer is at any liquid level that changes dynamically, it is no longer necessary to control the liquid level on the transducer to be kept fixed by the bottom structure of the water tank assembly, thereby being able to get rid of the ultrasonic wave. The humidifier's reliance on the water tank assembly achieves the goal of simplifying the structure and improving the atomization effect.
如图 1所示， 本发明提出的雾化装置包括： 用于盛放雾化液体（比如水、 药剂、 香剂等） 的水箱 1 , 该水箱 1的底部固定设置换能器 2, 且在水箱 1中 漂浮设置雾化增强部， 且雾化增强部的上表面随水箱 1 中液位变化而与液体 表面保持一致。  As shown in FIG. 1 , the atomization device proposed by the present invention comprises: a water tank 1 for containing an atomized liquid (such as water, a medicament, a fragrance, etc.), the bottom of which is fixedly provided with a transducer 2, and The atomization enhancement portion is floated in the water tank 1, and the upper surface of the atomization enhancement portion is kept in conformity with the liquid surface as the liquid level in the water tank 1 changes.
水箱 1可以为敞口容器或具有上盖的容器等， 水箱 1 中的液体可以直接 与水箱 1外的空气接触， 故不要求水箱 1具有密封性。  The water tank 1 may be an open container or a container having an upper cover, and the liquid in the water tank 1 may directly contact the air outside the water tank 1, so that the water tank 1 is not required to have a sealing property.
该雾化增强部包括： 引导筒 3 , 该引导筒 3的轴向中心线与换能器 2的轴 向中心保持基本一致， 引导筒 3 的轴向上具有圓柱形的贯通孔， 该贯通孔的 底部为进液口 31、 顶部为出雾口 32; 以及与引导筒 3固定连接且漂浮在水箱 1中液体表面的浮力部 4, 水箱 1中的液体对浮力部 4产生浮力使整个雾化增 强部漂浮在水箱 1中， 且浮力部 4为引导筒 3提供平衡力， 使引导筒 3的贯 通孔的轴向中心线与换能器 2 的轴向中心线保持一致， 以确保换能器产生的 超声水柱能顺利地从引导筒 3的进液口 31进入贯通孔， 在贯通孔中产生液雾 后从出雾口 32喷出。  The atomization enhancement portion includes: a guide cylinder 3 whose axial center line substantially coincides with the axial center of the transducer 2, and a cylindrical through hole in the axial direction of the guide cylinder 3, the through hole The bottom of the bottom is the liquid inlet 31, the top is the mist outlet 32; and the buoyancy portion 4 fixedly connected to the guiding cylinder 3 and floating on the liquid surface in the water tank 1, the liquid in the water tank 1 generates buoyancy to the buoyancy portion 4 to cause the entire atomization The reinforcing portion floats in the water tank 1, and the buoyancy portion 4 provides a balancing force for the guiding cylinder 3 so that the axial center line of the through hole of the guiding cylinder 3 coincides with the axial center line of the transducer 2 to ensure the transducer The generated ultrasonic water column can smoothly enter the through hole from the liquid inlet 31 of the guide cylinder 3, and liquid mist is generated in the through hole, and then ejected from the mist outlet 32.
随着水箱 1 中液体经雾化并被送出水箱 1后， 水箱 1 中液体逐渐减少， 因而水箱 1 中的液体表面位置也不断下降， 而雾化增强部则一直漂浮在液体 表面自动跟随水箱 1 中的液位变化而动态改变在其在水箱 1 中的相对位置。 在雾化增强部在运动过程中， 由于浮力部 4 的径向直径大于设置在换能器 2 周边的限位部 5的径向直径（其中， 引导筒 3的径向直径小于限位部 5的径 向直径）， 从而浮力部 4被限位部 5限制而使引导筒 3的底部无法触碰到换能 器 2 , 以确保超声水柱能从引导筒 3的进液口 31进入贯通孔。 As the liquid in the water tank 1 is atomized and sent out of the water tank 1, the liquid in the water tank 1 is gradually reduced, so that the liquid surface position in the water tank 1 is also continuously decreased, and the atomization enhancement portion is always floating on the liquid surface to automatically follow the water tank 1 The liquid level in the change changes dynamically in its relative position in the water tank 1. During the movement of the atomization reinforcement portion, since the radial diameter of the buoyancy portion 4 is larger than the radial diameter of the restriction portion 5 provided at the periphery of the transducer 2 (wherein the radial diameter of the guide cylinder 3 is smaller than the limit portion 5) Radial diameter), so that the buoyancy portion 4 is restricted by the limiting portion 5 so that the bottom of the guiding cylinder 3 cannot touch the transducing portion The device 2 ensures that the ultrasonic water column can enter the through hole from the liquid inlet 31 of the guiding cylinder 3.
为了确保提供浮力并尽可能地使引导筒 3保持平衡， 故浮力部 4需要产 生足够的浮力。 一般来说， 浮力部 4由密度小于水箱 1 中液体密度的材料制 成， 比如泡沫板。  In order to ensure that buoyancy is provided and the guide cylinder 3 is kept as balanced as possible, the buoyancy portion 4 needs to generate sufficient buoyancy. Generally, the buoyancy portion 4 is made of a material having a density lower than that of the liquid tank 1, such as a foam board.
结合图 2所示， 一般来说， 贯通孔的形状为圓柱形。 另外， 贯通孔的形 状还可以是进液口 31 的直径较大而出液口 32的直径较小的圓锥形、 或者下 部为圓锥形而靠近出液口 32的上部为圓柱形的圓锥台形。  As shown in Fig. 2, in general, the shape of the through hole is cylindrical. Further, the shape of the through hole may be a conical shape in which the diameter of the liquid inlet 31 is large and the diameter of the liquid outlet 32 is small, or a circle having a lower conical shape and a cylindrical portion near the upper portion of the liquid outlet 32. Cone shape.
在本发明的另一个实施例中， 如图 3 所示， 贯通孔的下部为一直径较大 的圓柱形、 中部为与下部直径一致的半球形、 上部为一直径较小的圓柱形。 本实施例可以利用贯通孔的结构， 当超声水柱进入贯通孔后， 经过贯通孔的 半球形中部平衡超声水柱对引导筒 3 生产的作用力， 从而使雾化增强部具有 自我定位功能， 使贯通孔的轴向中心线与换能器 2 的轴向中心线基本保持一 致， 确保雾化增强部位于换能器 2的上方。  In another embodiment of the present invention, as shown in Fig. 3, the lower portion of the through hole is a cylindrical shape having a larger diameter, the middle portion is a hemispherical shape conforming to the lower portion diameter, and the upper portion is a cylindrical shape having a smaller diameter. In this embodiment, the structure of the through hole can be utilized. After the ultrasonic water column enters the through hole, the hemispherical middle balance ultrasonic water column passing through the through hole can exert a force on the guiding cylinder 3, so that the atomization enhancement portion has a self-positioning function, so that the atomization enhancement portion has a self-positioning function. The axial centerline of the bore is substantially coincident with the axial centerline of the transducer 2, ensuring that the atomization enhancement is located above the transducer 2.
结合图 4所示， 在本发明另一个实施例中， 在引导筒 3的底端连接设置 限位环 6 , 该限位环 6的外形任何， 且外形尺寸大于限位部 5的尺寸， 使水箱 1中的液位较低时， 引导筒 3的底端通过限位环 6抵触在限位部 5的顶部， 从 而使引导筒 3的底端与换能器 2保持足够的距离。  As shown in FIG. 4, in another embodiment of the present invention, a limiting ring 6 is disposed at a bottom end of the guiding cylinder 3, and the outer shape of the limiting ring 6 is any larger than the size of the limiting portion 5, so that When the liquid level in the water tank 1 is low, the bottom end of the guiding cylinder 3 is in contact with the top of the limiting portion 5 through the limiting ring 6, so that the bottom end of the guiding cylinder 3 is kept at a sufficient distance from the transducer 2.
另外， 结合图 5所示， 在引导筒 3的外表面 /内表面上套设一个或多个套 筒 3，， 而限位环 6固定在最外 /最内的一个套筒 3，的底端， 通过套筒 3，可以变 相的调整引导筒 3的长度。 比如， 当水箱 1 中液位较低时， 此时多个套筒 3' 依次套接在引导筒 3 的外部， 此时超声水柱在雾化增强部中的运动距离等于 引导筒 3中贯通孔的轴向距离； 若水箱 1 中液位稍微增高， 在浮力部 4的作 用下带动雾化增强部漂浮在液面上， 带动套筒 3，在引导筒 3的外侧滑动， 从 而使超声水柱在雾化增强部中的运动距离增大； 当水箱 1 中液位足够高 （比 如液位高度为 20mm以上） 时， 在限位环 6的重力作用下， 引导筒 3与多个 套筒 3，之间均拉长至最大长度， 此时， 超声水柱在雾化增强部中的运动距离 进一步变大， 以此达到根据水箱 1 中液位高度不同来自动调节超声水柱在雾 化增强部中的运动距离， 增强雾化效果， 提高雾化效率。 In addition, as shown in FIG. 5, one or more sleeves 3 are sleeved on the outer surface/inner surface of the guiding cylinder 3, and the limiting ring 6 is fixed at the bottom of the outermost/innermost sleeve 3. At the end, the length of the guiding cylinder 3 can be adjusted in a phase-change manner by the sleeve 3. For example, when the liquid level in the water tank 1 is low, at this time, the plurality of sleeves 3' are sequentially sleeved outside the guiding cylinder 3, and the moving distance of the ultrasonic water column in the atomizing reinforcing portion is equal to the through hole in the guiding cylinder 3. If the liquid level in the water tank 1 is slightly increased, the atomizing reinforcement portion floats on the liquid surface under the action of the buoyancy portion 4, and the sleeve 3 is driven to slide outside the guiding cylinder 3, so that the ultrasonic water column is The moving distance in the atomization enhancement portion is increased; when the liquid level in the water tank 1 is sufficiently high (for example, the liquid level height is 20 mm or more), the guiding cylinder 3 and the plurality are guided by the gravity of the limiting ring 6 The sleeve 3 is elongated to the maximum length. At this time, the moving distance of the ultrasonic water column in the atomization enhancement portion is further increased, thereby automatically adjusting the ultrasonic water column according to the liquid level height in the water tank 1 to atomize. The moving distance in the reinforcement section enhances the atomization effect and improves the atomization efficiency.
为了确保本发明提出的雾化装置具有最佳的雾化效率， 可以在水箱 1 中 设置一个导向杯 8, 且导向杯 8的内径略大于浮力部 4的径向直径， 将雾化增 强部设置在导向杯 8之中以导向杯 8为导向随着液位变化而上下浮动。  In order to ensure that the atomization device proposed by the present invention has an optimum atomization efficiency, a guide cup 8 may be disposed in the water tank 1, and the inner diameter of the guide cup 8 is slightly larger than the radial diameter of the buoyancy portion 4, and the atomization enhancement portion is set. In the guide cup 8, guided by the guide cup 8, it floats up and down as the liquid level changes.
结合图 6所示， 若使用口径较大的水箱 1 , 在水箱 1的底部固定设置多根 (比如 2根、 3根或更多根）导向柱 9, 使多根导向柱 9之间形成的导向区域 略大于浮力部 4的外形， 从而将浮力部 4限制在多根导向柱 9之间形成的导 向区域之间进行运动。或者，在浮力部 4上设置多个导向孔（图 6中未画出）， 每根导向柱 9穿过其中一个导向孔， 使浮力部 4依据导向柱 9随着水箱 1中 的液体动态运动。  As shown in FIG. 6, if a water tank 1 having a large diameter is used, a plurality of (for example, two, three or more) guide columns 9 are fixedly disposed at the bottom of the water tank 1, so that a plurality of guide columns 9 are formed. The guiding area is slightly larger than the outer shape of the buoyancy portion 4, thereby restricting the buoyancy portion 4 from moving between the guiding regions formed between the plurality of guiding columns 9. Alternatively, a plurality of guide holes (not shown in FIG. 6) are disposed on the buoyancy portion 4, and each of the guide posts 9 passes through one of the guide holes, so that the buoyancy portion 4 moves in accordance with the liquid in the water tank 1 according to the guide post 9. .
贯通孔下端的孔径大小， 即进液口 31的径向直径， 必须小于换能器 2的 径向直径， 方可获得较佳的雾化增强效果。 较佳的， 进液口 31的径向直径为 换能器 2的径向直径的 30%~70%, 具体需要根据换能器 2的功率来选择： 当 换能器 2的功率较小时， 取上述范围值的下限值； 当换能器 2的功率较大时， 取上述范围值的上限值。  The size of the aperture at the lower end of the through hole, i.e., the radial diameter of the inlet port 31, must be smaller than the radial diameter of the transducer 2 for better atomization enhancement. Preferably, the radial diameter of the inlet port 31 is 30% to 70% of the radial diameter of the transducer 2, which is specifically selected according to the power of the transducer 2: when the power of the transducer 2 is small, The lower limit value of the range value is taken; when the power of the transducer 2 is large, the upper limit value of the range value is taken.
另外， 超声水柱在雾化增强部中的运动距离， 等于换能器 2产生的超声 波在水箱 1的液体中传播波长的 5倍〜 20倍。  In addition, the moving distance of the ultrasonic water column in the atomization enhancement portion is equal to 5 times to 20 times the wavelength of the ultrasonic wave generated by the transducer 2 in the liquid in the water tank 1.
另外， 将本发明的雾化装置应用在加湿器上时， 只需要增加一个含有超 声波驱动电路的机座， 将本发明的雾化装置设置在机座上， 即可形成超声波 加湿器。  Further, when the atomizing device of the present invention is applied to a humidifier, it is only necessary to add a base including an ultrasonic driving circuit, and the atomizing device of the present invention is placed on the base to form an ultrasonic humidifier.
以现有技术的雾化装置 （比如超声波加湿器）在液位高度（即换能器 2 上的液体的液位高度）分别是 50mm、 30mm, 20mm和 10mm时的雾化量的 平均值为 1 时， 测试本发明雾化装置的雾化量， 将测试得到的雾化量与现有 技术的平均雾化量进行对比， 得到相对雾化量列于表 1所示： The average amount of atomization of the prior art atomizing device (such as an ultrasonic humidifier) at the liquid level height (i.e., the liquid level of the liquid on the transducer 2) is 50 mm, 30 mm, 20 mm, and 10 mm, respectively. At 1 o'clock, the atomization amount of the atomization device of the present invention is tested, and the atomization amount obtained by the test is compared with the existing one. The average atomization amount of the technology is compared, and the relative atomization amount is shown in Table 1:

表 1  Table 1
表 1 中第 1行表示换能器上的液体的液位高度， 第 2行表示现有技术的 雾化装置在各个液位高度下的相对雾化量， 而第 3 行表示本申请雾化装置在 各个液位高度下的相对雾化量。  The first row in Table 1 indicates the liquid level height of the liquid on the transducer, the second row indicates the relative atomization amount of the prior art atomizing device at each liquid level height, and the third row indicates the atomization of the present application. The relative amount of atomization of the device at each level of liquid level.
上述表 1的相对雾化量均是对功率为 8W的换能器 2进行测试所获得。 从表 1可以看出， 在液位高度为 10mm时， 本申请的雾化效率是现有技术的 130%; 在液位高度为 20mm时， 本申请的雾化效率是现有技术的 152%; 在 液位高度为 30mm时， 本申请的雾化效率是现有技术的 225%; 在液位高度为 50mm时，现有技术的雾化装置几乎无法工作， 而本申请雾化装置仍然可以获 得。 由此可见， 相比现有技术而言， 本申请不仅在各个液位高度时均能够正 常工作， 而且在各个液位高度时均可以大幅提高雾化量。  The relative atomization amounts of Table 1 above were obtained by testing the transducer 2 with a power of 8W. It can be seen from Table 1 that the atomization efficiency of the present application is 130% of the prior art when the liquid level height is 10 mm; the atomization efficiency of the present application is 152% of the prior art when the liquid level height is 20 mm. When the liquid level height is 30mm, the atomization efficiency of the present application is 225% of the prior art; when the liquid level height is 50mm, the prior art atomization device can hardly work, and the atomization device of the present application can still obtain. It can be seen that compared with the prior art, the present application can work normally not only at the respective liquid level heights, but also greatly increase the atomization amount at each liquid level height.
并且， 从上述表 1 可以看出： 当釆用功率为 8W的换能器时， 换能器上 的液体的液位高度在 10~50mm时均能够获得较佳的雾化效率。 经实验证明， 即使换能器上的液体的液位高度在 80mm时也可以获得较佳的雾化效率。 另外， 釆用图 5所示的雾化增强部根据水箱 1 中的液位高度来变相调整 引导筒 3的长度， 使超声水柱在雾化增强部中的运动距离是可变化的。 此时， 在换能器 2至雾化增强部的限位环 6之间距离分别是 95mm、 25mm, 15mm 和 5mm时， 测试本申请的雾化装置（仍釆用功率为 8W的换能器 )的雾化量， 将 4种距离所测得的雾化量与该 4种距离所测得的雾化量的平均值对比， 得 到相应的相对雾化量列于表 2所示： 95mm 25mm 15mm 5mm 本申请 0.79 1.19 1.21 0.8 Moreover, it can be seen from the above Table 1 that when the transducer with a power of 8 W is used, a better atomization efficiency can be obtained when the liquid level of the liquid on the transducer is 10 to 50 mm. It has been experimentally proved that better atomization efficiency can be obtained even when the liquid level of the liquid on the transducer is at 80 mm. Further, the atomization enhancing portion shown in Fig. 5 is used to adjust the length of the guiding cylinder 3 in accordance with the liquid level height in the water tank 1, so that the moving distance of the ultrasonic water column in the atomizing reinforcing portion can be changed. At this time, when the distance between the transducer 2 and the limiting ring 6 of the atomization enhancing portion is 95 mm, 25 mm, 15 mm and 5 mm, respectively, the atomizing device of the present application (the transducer with a power of 8 W is still used) The amount of atomization is compared with the average of the atomization amount measured by the four distances and the atomization amount measured by the four distances, and the corresponding relative atomization amount is shown in Table 2: 95mm 25mm 15mm 5mm This application is 0.79 1.19 1.21 0.8
表 2  Table 2
表 2中第 1行表示换能器 2至雾化增强部的限位环 6之间距离， 第 2行 表示本申请的雾化装置在各个距离下的相对雾化量。 从表 2 可以看出， 当换 能器 2至雾化增强部的限位环 6之间距离介于 5mm与 95mm之间时，本申请 的雾化装置均能够正常工作且获得雾化效率较高的雾化效果。 尤其是在换能 器 2至雾化增强部的限位环 6之间距离介于 15mm与 25mm之间时， 使用本 申请的雾化装置不仅能够获得雾化效率较高的雾化效果， 还可以获得雾化量 相对保持稳定的雾化效果。  The first row in Table 2 indicates the distance between the transducer 2 and the stopper ring 6 of the atomization enhancing portion, and the second row indicates the relative atomization amount of the atomizing device of the present application at various distances. It can be seen from Table 2 that when the distance between the transducer 2 and the limiting ring 6 of the atomization enhancing portion is between 5 mm and 95 mm, the atomizing device of the present application can work normally and obtain the atomization efficiency. High atomization effect. In particular, when the distance between the transducer 2 and the limiting ring 6 of the atomization enhancing portion is between 15 mm and 25 mm, the atomizing device of the present application can not only obtain the atomization effect with high atomization efficiency, but also It is possible to obtain an atomization effect in which the amount of atomization is relatively stable.
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本 发明的精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本 发明的保护范围之内。  The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention.
