Description

Technical Field

[0001] This utility model relates to the field of atomizing devices, specifically to the field of ultrasonic atomizing devices. Background Technology

[0002] In existing ultrasonic atomization technologies, non-contact solutions that indirectly atomize the liquid through liquid conduction have been applied. These solutions can avoid direct contact between the ultrasonic transducer and the corrosive liquid when atomizing it. Most existing technologies use vertically incident or simply tilted ultrasonic waves for conduction, resulting in generally low atomization efficiency. This often requires a significant increase in input power to compensate for energy loss, which not only increases energy consumption but also accelerates equipment aging. Utility Model Content

[0003] Therefore, one objective of this utility model is to propose an acoustic atomizing device that improves atomization efficiency by optimizing the ultrasonic incident angle.

[0004] This utility model provides a sonic atomizing device, including a housing, with a partition inside the housing dividing the housing into an upper medium cavity and a lower mounting cavity. An atomizing groove is provided within the medium cavity, and the atomizing groove has two opposing vertical sidewalls. The partition includes a symmetrically arranged first loading surface and a second loading surface. The horizontal distance H between the first loading surface, the second loading surface, and the adjacent sidewall is 0 to 50 mm, and they are inclined upwards at 10° to 50° relative to the horizontal plane. Atomizing plates are provided on the first loading surface and the second loading surface, facing the sidewall and higher than the bottom edge of the sidewall.

[0005] Furthermore, the angle between the first loading surface, the second loading surface and the horizontal plane is 37°.

[0006] Furthermore, the horizontal distance H is 5 millimeters.

[0007] Furthermore, the length of the atomizing groove is the same as the length of the medium cavity.

[0008] Furthermore, the top of the atomizing groove is provided with a hanging ear, and the top of the housing is provided with a mounting base, the hanging ear abutting against the mounting base.

[0009] Furthermore, three atomizing plates are evenly disposed on the first loading surface and the second loading surface, respectively.

[0010] Furthermore, the atomizing plates are arranged on the same horizontal plane.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The directional transmission of ultrasonic energy is achieved by tilting the first and second loading surfaces, ensuring that the ultrasonic propagation path forms the optimal angle with the sidewall of the atomizing tank, thereby improving energy transfer efficiency and atomization uniformity.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this invention, "acoustic medium" refers to the atomization technology path that transmits ultrasonic waves through an intermediate medium. "Acoustic" specifically refers to the ultrasonic waves generated by the ultrasonic atomizing plate, and "medium" indicates the transmission method in which ultrasonic waves indirectly act on the liquid to be atomized through the ultrasonic conductive liquid as an intermediary substance, thereby achieving efficient transmission while avoiding direct contact between the atomizing plate and the liquid to be atomized.

[0021] like Figure 1 , Figure 2As shown, the acoustic atomizing device includes a cuboid housing 10 with an opening at the top. A partition 20 is provided inside the housing 10, dividing it into two parts: an upper media cavity 11 and a lower mounting cavity 12. The mounting cavity 12 is used to mount relevant control and drive electronic components. A cuboid atomizing groove 30 is provided within the media cavity 11, and the atomizing groove 30 has two opposing vertical sidewalls 31.

[0022] like Figure 3 , 4 As shown, the partition 20 is symmetrically provided with a first loading surface 21 and a second loading surface 22. The first loading surface 21 and the second loading surface 22 are located on the outer sides of the two vertical sidewalls 31 of the atomizing tank 30, and are both inclined upwards relative to the horizontal plane. Mounting holes 23 and fixing holes 24 are provided on the first loading surface 21 and the second loading surface 22, penetrating the respective loading surfaces. The mounting holes 23 are used to place the atomizing plate 40, and the atomizing plate 40 is fixed on the respective loading surface by fixing bolts passing through the fixing holes 24, and the atomizing plate 40 is on the same plane as the loading surface. Because the first loading surface 21 and the second loading surface 22 are inclined upwards, the atomizing plate 40 installed on the first loading surface 21 and the second loading surface 22 also forms an angle with the adjacent sidewall 31 of the atomizing tank 30. In order to allow as much ultrasonic wave emitted by the atomizing plate 40 as possible to be transmitted into the atomizing tank 30 through the sidewall 31, the height of the atomizing plate 40 should be lower than the bottom edge 310 of the sidewall 31.

[0023] The angle between the ultrasonic wave emitted by the atomizing plate 40 and the corresponding side wall 31 is the incident angle of the ultrasonic wave. According to the structure of the acoustic atomizing device, this angle is equal to the angle between the first and second loading surfaces and the horizontal plane. Therefore, by tilting the first and second loading surfaces upward, the incident angle of the ultrasonic wave can be accurately determined.

[0024] In use, an ultrasonic conductive fluid is injected into the medium cavity 11, and the liquid to be atomized is injected into the atomizing tank 30. The atomizing plate 40 emits ultrasonic waves, which are transmitted through the ultrasonic conductive fluid to the side wall 31 of the atomizing tank 30 and enter the atomizing tank 30 at a certain incident angle after refraction, acting on the liquid to be atomized. Because ultrasonic waves undergo refraction, reflection, and waveform conversion when propagating in different media, the incident angle of the ultrasonic waves entering the atomizing tank 30 directly determines the energy distribution and atomization effect. Specifically, according to Snell's law... According to the law, the ratio of the sine of the incident angle to the sine of the refraction angle of the ultrasonic wave is equal to the ratio of the wave velocities in the two media. This means that changing the incident angle will directly change the propagation direction of the ultrasonic wave at the side wall 31. Different propagation directions result in different path lengths for the ultrasonic wave to reach the surface of the liquid to be atomized. The longer the path during transmission, the greater the energy loss. Therefore, different incident angles will cause different energy of the ultrasonic wave to ultimately act on atomization, thus affecting the atomization effect. Secondly, the change of the incident angle will also change the reflection coefficient and refraction coefficient of the ultrasonic wave at the side wall 31. These two coefficients determine the amplitude of the reflected wave and the refracted wave, respectively. The energy of the wave is proportional to the square of the amplitude. Therefore, the change of the reflection coefficient and refraction coefficient will directly affect the distribution ratio of ultrasonic energy on the reflection and refraction paths. Furthermore, at certain incident angles, when the ultrasonic wave hits the surface of the side wall 31, waveform conversion will also occur, such as the conversion of longitudinal waves into transverse waves. The sound velocities of different waveforms are different, which makes the distribution of energy among the different waveforms after conversion more complex, and will ultimately affect the energy distribution of the refracted waves that enter the liquid to be atomized and are used for atomization.

[0025] With water used for both the ultrasonic transducer and the atomizing fluid, the atomization effect at different incident angles was tested, and the results are shown in the table below:

[0026]

[0027] According to the tests, when both the ultrasonic transmitting liquid and the liquid to be atomized are water, the incident angle has a significant impact on the atomization effect. The atomization effect is weaker when the incident angle is 10° or 50°, while the atomization amount reaches its maximum when the incident angle is 37°. Within the range of 10° to 37°, the atomization effect gradually increases with increasing angle; however, the opposite trend is observed in the range of 38° to 50°.

[0028] Therefore, the incident angle should be set between 10° and 50°, that is, the upward tilt angle of the first loading surface 21 and the second loading surface 22 relative to the horizontal plane should be set between 10° and 50°.

[0029] Preferably, the first loading surface 21 and the second loading surface 22 should be tilted upward at an angle of 37° relative to the horizontal plane. At this time, the incident angle of the ultrasonic wave transmitted to the atomizing tank 30 is 37°. According to the test results, a better atomization effect can be achieved at this incident angle.

[0030] Furthermore, the horizontal distance H between the first loading surface 21 or the second loading surface 22 and the side wall 31 of the adjacent atomizing tank 30 also has a significant impact on the atomization effect. With water used for both the ultrasonic conductive fluid and the fluid to be atomized, the atomization effect at different horizontal distances H was tested at an incident angle of 37°, and the results are shown in the table below:

[0031]

[0032] Within the range of 0 to 50 mm, the smaller the distance, the lower the ultrasonic energy loss, and the more concentrated the energy acts on the atomizing tank 30, thereby improving efficiency.

[0033] Preferably, the horizontal distance H is 5mm, which can balance the compactness of the atomizing device structure and the atomization efficiency.

[0034] Optionally, the length of the atomizing groove 30 is the same as the length of the medium cavity 11, which can maximize the use of the space of the medium cavity 11 and maximize the capacity of the atomizing groove 30.

[0035] Furthermore, the top of the atomizing groove 30 that abuts against the housing 10 is folded outward horizontally to form a hanging ear 32, and the top of the housing 10 is also folded outward horizontally at the corresponding position to form a mounting base 13. The hanging ear 32 abuts against the mounting base 13 to connect the atomizing groove 30 and the housing 10.

[0036] Preferably, three atomizing plates 40 are evenly arranged on the first loading surface 21 and the second loading surface 22 respectively, which improves atomization efficiency and output while ensuring the compact structure of the entire atomizing device.

[0037] Furthermore, the six atomizing plates 40 on the first loading surface 21 and the second loading surface 22 are all positioned on the same horizontal plane to ensure structural symmetry and consistency of atomization effect.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0039] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0040] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
