[0053] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0054] The airflow regulator 2 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The airflow regulator 2 can be used to form a wind field or to regulate a wind field.

[0055] According to a first aspect of the present invention, an airflow regulating member 2 includes a vibrating plate 22 and a driver 21, wherein the driver 21 is disposed on the vibrating plate 22 and is used to drive the vibrating plate 22 to reciprocate.

[0056] When the airflow regulator 2 is used to form a wind field, the vibrating plate 22 is driven to reciprocate by the driver 21. This vibration can induce airflow and form an airflow path, thereby forming a wind field, which can replace the impeller 50 to achieve the function of air delivery. When the airflow regulator 2 is used to adjust the wind field, the airflow regulator 2 can be used in conjunction with the impeller 50. The impeller 50 acts as an air delivery component to deliver air. When it is necessary to adjust the wind field formed by the impeller 50, the airflow regulator 2 can be turned on, so that the driver 21 works to drive the vibrating plate 22 to reciprocate and turbulent the airflow. This turbulence can adjust the wind field formed by the impeller 50. For example, the wind direction, wind speed, and wind feel of the wind field formed by the impeller 50 can be adjusted to make the airflow more diverse and meet more user needs.

[0057] The driver 21 can be one, and there can be multiple vibrating plates 22. The driver 21 is connected to each vibrating plate 22 to drive the vibrating plate 22 to reciprocate. At least two of the vibrating plates 22 have different natural frequencies. The driver 21 is adapted to drive all the vibrating plates 22 with the same natural frequency to resonate.

[0058] It should be explained that "a plurality of" in this invention refers to two or more.

[0059] Understandably, "resonance," also known as "resonance," occurs when the frequency of the driving force equals the system's natural frequency, resulting in the maximum amplitude of forced vibration. This phenomenon is called resonance. In an oscillating system under periodic external forces, when the frequency of the external force is the same as or very close to the system's natural oscillation frequency, the amplitude increases dramatically. The frequency at which resonance occurs is called the "resonant frequency." Furthermore, "natural frequency," also called "natural frequency," refers to the frequency of free vibration. When an object vibrates freely, its displacement changes with time according to a sine or cosine law. The frequency of vibration is independent of initial conditions and depends only on the system's inherent characteristics (such as mass, shape, and material). This is called the natural frequency, and its corresponding period is called the natural period. The natural frequency is unrelated to external excitation; it is an inherent property of the structure. Regardless of whether external excitation is applied to the structure, its natural frequency exists. However, when external excitation occurs, the structure vibrates according to its natural frequency. In addition, "free vibration" refers to the vibration that occurs in a mechanical system after the excitation or constraint is removed. The vibration is maintained only by its elastic restoring force. When damping is applied, the vibration gradually decays. The frequency of free vibration is determined only by the physical properties of the system itself and is called the natural frequency of the system.

[0060] In simple terms, when the excitation frequency of the driver 21 is the same as or close to the natural frequency of at least one of the multiple vibrating plates 22, the resonance effect is utilized. The vibration generated by the vibrating plate 22 in this case is called resonance, and the amplitude of the vibrating plate 22 will increase sharply. Therefore, the vibrating plate 22 can effectively regulate the airflow, generating a wind-blowing effect that induces airflow to form a wind field or effectively regulate the wind field. Otherwise, it is ordinary vibration.

[0061] Since at least two of the vibrating plates 22 in the airflow regulating component 2 of the present invention have different natural frequencies, when the airflow regulating component 2 is working, the frequency of the alternating voltage applied to the driver 21 (i.e., the excitation frequency of the driver 21) can be made close to or the same as the frequency of the vibrating plate 22 that needs to resonate, so that the vibrating plate 22 can resonate and the amplitude of the vibrating plate 22 that resonates is larger. Therefore, the vibration amplitude of the vibrating plate 22 can be larger, thereby increasing the airflow regulating effect of a single airflow regulating component 20. When the airflow regulating component 2 is used to form a wind field, the induced air volume and the supplied air volume of a single airflow regulating component 2 can be increased, which can simply and effectively meet the air supply requirements; when the airflow regulating component 2 is used to regulate the wind field, the regulating force of a single airflow regulating component 20 on the wind field can be increased, achieving the expected regulating effect. When there are vibrating plates 22 with the same natural frequency among multiple vibrating plates 22, when the excitation frequency of the driver 21 is close to or the same as the natural frequency of the vibrating plate 22, all vibrating plates 22 with the same natural frequency will resonate.

[0062] Therefore, by adjusting the frequency of the alternating voltage applied to the driver 21, the vibration plate 22 with a different inherent frequency can be switched to resonate, thereby changing the resonant frequency of the airflow regulator 2, realizing the switching of the airflow regulator 2 between multiple different vibration frequencies, and meeting more air outlet requirements.

[0063] Since at least two of the vibrating plates 22 in the airflow regulator 2 of this invention have different natural frequencies, the vibration frequency of the airflow regulator 2 can be changed. This allows the airflow regulator 2 to have multiple airflow regulation modes with different resonant frequencies, enabling it to switch to different airflow regulation modes as needed. Switching the airflow regulator 2 to different airflow regulation modes is achieved by changing the frequency of the alternating voltage applied to the driver 21, making control simple and convenient. In different airflow regulation modes, the natural frequencies of the resonating vibrating plates 22 are different, resulting in different resonant frequencies for the airflow regulator 2. Therefore, the intensity of the regulated airflow can be changed in different airflow regulation modes.

[0064] It should be noted that when the driver 21 drives the vibrating plate 22 whose natural frequency is close to or the same as the excitation frequency of the driver 21 to resonate, other vibrating plates 22 may vibrate slightly. When other vibrating plates 22 vibrate, their vibration amplitude is smaller than that of the vibrating plate 22 that resonates.

[0065] When a higher resonant frequency of the vibrating plate 22 is required, the excitation frequency applied to the driver 21 can be made close to or the same as the natural frequency of the vibrating plate 22 with a higher natural frequency, so that the vibrating plate 22 can vibrate at a higher resonant frequency; when a lower resonant frequency of the vibrating plate 22 is required, the excitation frequency applied to the driver 21 can be made close to or the same as the natural frequency of the vibrating plate 22 with a lower natural frequency, so that the vibrating plate 22 can vibrate at a lower resonant frequency.

[0066] The vibration frequency primarily affects the wind speed. Generally, a higher vibration frequency results in a higher wind speed, and vice versa. When the airflow regulating component 2 is used to create a wind field, the wind speed can be adjusted by regulating the vibration frequency of the aforementioned vibration unit to meet various airflow requirements. When the airflow regulating component 2 is used to regulate the wind field, the vibration frequency of the aforementioned vibration unit can be adjusted to create different disturbances to the wind field, thereby regulating the wind speed, wind feel, etc., to diversify the airflow and meet more user needs.

[0067] For example, in the airflow regulation mode with a higher resonant frequency, the airflow regulator 2 has a stronger airflow regulation effect. When used to form a wind field, it can result in a higher wind speed; when used to regulate the wind field, it can achieve a greater degree of wind field regulation. In the airflow regulation mode with a lower resonant frequency, the airflow regulator 2 has a weaker airflow regulation effect. When used to form a wind field, it can result in a lower wind speed; when used to regulate the wind field, it can achieve a smaller degree of wind field regulation. By enabling the airflow regulator 2 to have multiple airflow regulation modes with different resonant frequencies, it can be switched to different airflow regulation modes as needed to form different wind fields or to regulate the wind field differently, thereby meeting more diverse air supply requirements.

[0068] Optionally, the vibrating plates 22 with different natural frequencies have different masses. Mass is an important factor affecting the natural frequency. By setting vibrating plates 22 with different masses, it is easy to achieve different natural frequencies for the vibrating plates 22. For example, if each vibrating plate 22 has a different natural frequency, this can be achieved by making each vibrating plate 22 have a different mass.

[0069] Optionally, when the vibrating plates 22 with different natural frequencies have different masses, the thickness of the vibrating plates 22 with different natural frequencies can be the same, thereby making the structure of the vibrating plate 22 simple and convenient to process and manufacture.

[0070] Optionally, when the vibrating plates 22 with different natural frequencies have different masses, the vibrating plates 22 with different natural frequencies can be made of the same material, thereby making the structure of the vibrating plate 22 simple and easy to process and manufacture.

[0071] Optionally, when the vibrating plates 22 with different natural frequencies have different masses, the thickness and material of the vibrating plates 22 with different natural frequencies can be the same, thereby making the structure of the vibrating plate 22 simple and convenient to process and manufacture.

[0072] Optionally, when multiple vibrating plates 22 have the same natural frequency, the mass of the vibrating plates 22 with the same natural frequency can be the same. Furthermore, when the mass of the vibrating plates 22 with the same natural frequency is the same, the thickness, material, size, and shape of the vibrating plates 22 with the same natural frequency can also be the same, that is, the vibrating plates 22 with the same natural frequency are identical. This simplifies the structure and types of vibrating plates 22.

[0073] Optionally, all vibrating plates 22 have the same thickness and material, but vibrating plates 22 with different natural frequencies have different masses, while vibrating plates 22 with the same natural frequency have the same mass.

[0074] According to an embodiment of the present invention, the airflow regulating component 2 is provided with a driver 21 and a plurality of vibrating plates 22, and the driver 21 is connected to each vibrating plate 22 to drive the vibrating plate 22 to reciprocate. At the same time, at least two of the vibrating plates 22 have different natural frequencies, so that the vibration frequency of the airflow regulating component 2 can be changed, and the switching between multiple different frequencies can be realized to meet more air outlet requirements.

[0075] According to some embodiments of the present invention, the actuator 21 may include at least one of the following: inverted piezoelectric actuator, electrostrictive actuator, magnetostrictive actuator, shape memory alloy actuator, mechanical actuator, servo actuator, and electrorheological fluid actuator.

[0076] For example, the actuator 21 can be an inverse piezoelectric actuator, employing the inverse piezoelectric effect. Specifically, the actuator 21 can be a piezoelectric sheet, such as a piezoelectric ceramic sheet. The inverse piezoelectric effect of the sheet causes it to reciprocate, driving the aforementioned vibration unit to resonate, thereby forming or regulating a wind field. Alternating current can be used to drive the piezoelectric sheet to produce the inverse piezoelectric effect, thus driving the aforementioned vibration unit to resonate.

[0077] For example, when the actuator 21 is a piezoelectric element, an alternating voltage is applied in the polarization direction of the piezoelectric element, causing the piezoelectric element to undergo periodic mechanical deformation in a certain direction. Resonance (or synchrotron resonance) occurs only when the excitation frequency of the piezoelectric element (the excitation frequency of the piezoelectric element is the frequency of the alternating voltage applied to the piezoelectric element) is equal to or close to the natural frequency of the aforementioned vibration unit. At this time, the amplitude of the vibration unit will increase sharply, thereby enabling the vibration unit to more effectively regulate the airflow, thus forming or regulating a wind field.

[0078] Optionally, the voltage amplitude of the alternating voltage applied to the driver 21 is adjustable. When the vibrating plate 22 of the airflow regulator 2 resonates, the amplitude of the vibrating plate 22 can be further adjusted by changing the voltage amplitude of the alternating voltage applied to the operating driver 21, thereby further realizing the formation of different wind fields or different adjustments to the wind fields, resulting in more diversified airflow and more precise control over the airflow.

[0079] For example, the actuator 21 can be an electrostrictive actuator, which drives the aforementioned vibration unit to resonate through the electrostrictive effect. Specifically, the electrostrictive effect refers to the phenomenon of elastic deformation of a dielectric in an electric field. This phenomenon can be explained as follows: when a dielectric is placed in an electric field, its molecules become polarized, with the positive pole of one molecule connecting to the negative pole of another molecule along the direction of the electric field. Due to the mutual attraction between the positive and negative poles, the entire dielectric contracts in this direction until the elastic force and electro-attraction within it are balanced. In short, the electrostrictive actuator can be deformed by alternating current, thereby causing the vibration unit to resonate.

[0080] Furthermore, it should be noted that the difference between electrostriction and the inverse piezoelectric effect lies in the following: the inverse piezoelectric effect is a linear response effect with a first-order term, and can only occur in solid dielectrics without a center of symmetry. The piezoelectric constant is a third-order tensor; the physical property parameters describing the electrostriction effect in anisotropic dielectrics are fourth-order tensors. In non-piezoelectric dielectrics, only the electrostriction effect occurs; in piezoelectric materials, both the piezoelectric and electrostriction effects occur simultaneously. Generally, the strain caused by the electrostriction effect is several orders of magnitude smaller than that caused by the inverse piezoelectric effect in piezoelectric materials.

[0081] For example, the actuator 21 can also be a magnetostrictive actuator, driving the vibrating unit to resonate through the magnetostrictive effect. Specifically, the magnetostrictive effect refers to the phenomenon where an object, when magnetized in a magnetic field, elongates or shortens in the direction of magnetization. Ferromagnetic materials, whose dimensions change significantly when the current through the coil changes or the distance from the magnet changes, are commonly called ferromagnetic materials. Their dimensional changes are much larger than those of current magnetostrictive materials such as ferrites, and they also generate more energy; therefore, they are called supermagnetic materials. Because the length of a magnetostrictive material changes under the influence of a magnetic field, it can undergo displacement and do work, or it can repeatedly stretch and shorten under the influence of an alternating magnetic field, thus generating vibration. This material can convert electromagnetic energy (or electromagnetic information) into mechanical energy. In short, the magnetostrictive actuator is deformed by an alternating magnetic field, thereby causing the vibrating unit to resonate.

[0082] For example, the actuator 21 can be a shape memory alloy actuator, driving the vibration unit to resonate through the deformation of the shape memory alloy. Specifically, shape memory alloys (SMA) undergo a martensitic phase transformation under external fields (temperature, stress, magnetic fields, etc.), exhibiting shape memory and superelasticity, outputting force and displacement. They are advanced intelligent materials integrating temperature sensing and intelligent actuation, possessing unique shape memory effects and phase transformation pseudoelasticity, and are widely used in aerospace, medical devices, and mechanical and electrical fields. Shape memory alloys have three characteristics: large deformation; large degree of freedom in displacement direction; and rapid displacement. Therefore, they feature large displacement, high power-to-weight ratio, rapid displacement, and directional freedom. They are particularly suitable for low-load, high-speed, high-precision robotic assembly operations, sample movement devices within microscopes, reactor drive devices, medical endoscopes, artificial hearts, detectors, and protectors. In short, the temperature of the shape memory alloy actuator is changed by heating or cooling, and the deformation of the shape memory alloy actuator is driven by the change in temperature field, thereby causing the vibration unit to resonate.

[0083] For example, the actuator 21 can be an electrorheological fluid actuator, which drives the vibration unit to resonate by deforming the electrorheological fluid. Specifically, an electrorheological fluid (ERF) is a smart material whose viscosity changes with the strength of the applied electric field. Without an electric field, the ERF flows freely like a normal liquid, essentially a Newtonian fluid. When the applied electric field strength reaches a certain value, the properties of the ERF change significantly: the viscosity increases and gradually loses fluidity, shear resistance increases, and it rapidly transforms from a liquid to a near-solid state. After the electric field is removed, it quickly returns to a liquid state. This state change can be achieved in just milliseconds, and this transformation is completely reversible. In short, the alternating electric field drives the electrorheological fluid actuator to deform, thereby causing the vibration unit to resonate.

[0084] For example, the driver 21 can be a servo actuator, which can be a hydraulic actuator that converts hydraulic energy from a hydraulic source into mechanical energy. It can also be servo controlled via a built-in displacement sensor or limit switch as needed. It executes commands from the main controller to control the load's speed, direction, displacement, and force, while simultaneously feeding back signals to the main controller. It features high output force, accurate positioning, and small size. In short, the servo actuator drives the vibration unit to resonate.

[0085] For example, the driver 21 can also be a mechanical actuator, which can be driven directly by a high-speed motor or driven by a mechanical mechanism to cause the vibration unit to resonate, etc., which will not be elaborated here.

[0086] According to some embodiments of the present invention, with reference to Figures 1-15 The driver 21 is located at the root 221 of each vibrating plate 22. The root 221 of the vibrating plate 22 refers to the fixed end of the vibrating plate 22, and the tip 222 refers to the free end of the vibrating plate 22. The vibrating plate 22 can be elongated, with the root 221 and the tip 222 at its two ends along its length. The root 221 can be fixed. When the vibrating plate 22 vibrates, the tip 222 is located downstream of the root 221, and the airflow generally flows from the root 221 to the tip 222. When the driver 21 is energized, the tip 222 of the vibrating plate 22 can undergo a large vibration displacement, resulting in low energy consumption during operation of the airflow regulator 2. Furthermore, the airflow regulation effect of the vibrating plate 22 when it vibrates is easy to control, which makes it easier to control the wind field formed by the airflow regulator 2 or the wind field regulation, so that the wind field formed by the airflow regulator 2 or the wind field regulation can more easily meet the expected requirements.

[0087] According to some embodiments of the present invention, with reference to Figures 1-15 When the actuator 21 is a piezoelectric element, the actuator 21 can be located on one side of the vibrating plate 22 along its thickness direction, or on both sides of the vibrating plate 22 along its thickness direction. The actuator 21 and the vibrating plate 22 can be stacked along the thickness direction of the vibrating plate 22. (Refer to...) Figures 1-8 When the driver 21 is located on both sides of the thickness direction of the vibrating plate 22, each driver 21 may include two sub-drivers 210 (i.e. each piezoelectric plate includes two sub-piezoelectric plates). The two sub-drivers 210 of each driver 21 are located on both sides of the thickness direction of the vibrating plate 22, and the two sub-drivers 210 of each driver 21 are arranged opposite to each other along the thickness direction of the vibrating plate 22. The two sub-drivers 210 of each driver 21 may be the same.

[0088] According to some optional embodiments of the present invention, refer to Figures 1-12 The driver 21 is located at the root 221 of each vibrating plate 22. The roots 221 of all vibrating plates 22 are connected as a whole by connecting pieces 23. When the driver 21 drives at least one vibrating plate 22 to resonate, since the roots 221 of all vibrating plates 22 are connected by the connecting pieces 23, the resonating vibrating plate 22 will drive the other vibrating plates 22 to vibrate. This not only causes the resonating vibrating plate 22 to regulate airflow, but also the other vibrating plates 22, thus strengthening the airflow regulation effect and improving the airflow regulation effect of the airflow regulator 2. However, since the other vibrating plates 22 do not resonate, the amplitude of their vibration is smaller than that of the resonating vibrating plate 22.

[0089] Optionally, all vibrating plates 22 and connecting plates 23 can be integrally molded. This simplifies the assembly process of connecting the vibrating plates 22 and the connecting plates 23, while ensuring reliable connection strength at the joint between the vibrating plates 22 and the connecting plates 23, reducing the probability of breakage during repeated reciprocating vibrations.

[0090] Optionally, the connecting plate 23 and all the vibrating plates 22 can be arranged in the same plane, which is perpendicular to the thickness direction of the vibrating plates 22. Therefore, when the vibrating plates 22 vibrate along their own thickness direction, it is not necessary to consider whether the gaps between the vibrating plates 22 in the thickness direction are sufficient for the vibrating plates 22 to vibrate, facilitating the arrangement of all the vibrating plates 22. Furthermore, this arrangement can reduce the size of the airflow regulating component 2 in the thickness direction of the vibrating plates 22. In addition, since all the vibrating plates 22 are arranged in a plane perpendicular to the thickness direction of the vibrating plates 22, the airflow regulating effect of all the vibrating plates 22 can be effectively increased, improving the airflow regulation effect, thereby enhancing the air delivery effect or the effect of regulating the airflow field.

[0091] Optionally, when the airflow regulating component 2 includes the connecting piece 23 described above, the driver 21 can be connected to the root 221 of each vibrating plate 22, and the driver 21 can also be connected to the connecting piece 23. For example, the driver 21 can be a piezoelectric piece, and the driver 21 can be located on one side of the thickness direction of the vibrating plate 22, or on both sides of the thickness direction of the vibrating plate 22. The driver 21 and the vibrating plate 22 can be stacked along the thickness direction of the vibrating plate 22. (Refer to...) Figures 1-14 When the actuator 21 is located on both sides of the vibrating plate 22 in the thickness direction, each actuator 21 includes two sub-actuators 210 (i.e., each piezoelectric plate includes two sub-piezoelectric plates). The two sub-actuators 210 of each actuator 21 are located on both sides of the vibrating plate 22 in the thickness direction, and the two sub-actuators 210 of each actuator 21 are arranged opposite to each other along the thickness direction of the vibrating plate 22. The two sub-actuators 210 of each actuator 21 can be identical. Part of each sub-actuator 210 is located on the connecting piece 23, and another part is located at the root 221 of each actuator 21.

[0092] In other embodiments of the present invention, the airflow regulating member 2 may not include the connecting piece 23 described above, and the roots 221 of all the vibrating pieces 22 are not connected as one unit by the connecting piece 23.

[0093] According to some embodiments of the present invention, each vibrating plate 22 has a different natural frequency. With the same number of vibrating plates 22, by making each vibrating plate 22 have a different natural frequency, the airflow regulator 2 can have more different vibration frequencies, making the airflow regulation mode of the airflow regulator 2 more diverse and meeting more diverse air supply needs.

[0094] For example, all the vibrating plates 22 have different natural frequencies. There are N vibrating plates 22, which are designated as the first to the Nth vibrating plates 22. The driver 21 is located at the root 221 of each vibrating plate 22. The airflow regulating component 2 has N airflow regulating modes, each with a different resonant frequency. These N airflow regulating modes are designated as the first to the Nth airflow regulating modes. In the Mth airflow regulating mode, the driver 21 drives the Mth vibrating plate 22 to resonate, where N ≥ 2 and is an integer, and 1 ≤ M ≤ N and is an integer. Since each vibrating plate 22 has a different natural frequency, the excitation frequency of the driver 21 can be controlled to be close to or the same as the natural frequency of the Mth vibrating plate 22, thereby causing the Mth vibrating plate 22 to resonate, achieving the desired resonant frequency and airflow regulating effect.

[0095] Additionally, the voltage applied to the driver 21 can be adjusted accordingly to change the amplitude, depending on the requirements. When the airflow regulator 2 is used for air outlet, different airflow regulation modes can produce different wind speeds. When the amplitudes are similar, the higher the resonant frequency, the higher the wind speed.

[0096] Optionally, the natural frequencies of the first to Nth vibrating plates 22 can be set to increase or decrease sequentially, for example, the masses of the first to Nth vibrating plates 22 can be set to decrease or increase sequentially.

[0097] For example, in Figures 1-6 as well as Figure 13In the example, there are two vibrating plates 22, each with a different natural frequency. These two vibrating plates 22 are designated as a first vibrating plate 224 and a second vibrating plate 225. The driver 21 is located at the root 221 of each vibrating plate 22. The airflow regulator 2 has two airflow regulation modes with different resonant frequencies: a first airflow regulation mode and a second airflow regulation mode. In the first airflow regulation mode, the driver 21 drives the first vibrating plate 224 to resonate at its natural frequency, while the second vibrating plate 225 may experience slight vibration. In the second airflow regulation mode, the driver 21 drives the second vibrating plate 225 to resonate at its natural frequency, while the first vibrating plate 224 may experience slight vibration. Since the natural frequencies of the first vibrating plate 224 and the second vibrating plate 225 are different, the resonant frequencies of the first flow regulation mode and the second flow regulation mode are different. By controlling the excitation frequency of the driver 21, the excitation frequency of the driver 21 can be switched between the natural frequencies of the first vibrating plate 224 and the second vibrating plate 225, thereby enabling the airflow regulator 2 to switch between the first airflow regulation mode and the second airflow regulation mode.

[0098] The natural frequency of the first vibrating plate 224 can be lower than the natural frequency of the second vibrating plate 225, for example, the mass of the first vibrating plate 224 is greater than the mass of the second vibrating plate 225. If a higher wind speed or a greater degree of wind field adjustment is required, the system can switch to the second airflow adjustment mode; if a lower wind speed or a greater degree of wind field adjustment is required, the system can switch to the first airflow adjustment mode.

[0099] For example, in Figures 7-12 as well as Figure 14In the example, there are three vibrating plates 22, each with a different natural frequency. The three vibrating plates 22 are designated as the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226. The driver 21 is located at the root 221 of each vibrating plate 22. The airflow regulator 2 has three airflow regulation modes with different resonant frequencies: the first airflow regulation mode, the second airflow regulation mode, and the third airflow regulation mode. In the first airflow regulation mode, the driver 21 drives the first vibrating plate 224 to resonate, and the resonant frequency is the natural frequency of the first vibrating plate 224. The second vibrating plate 225 and the third vibrating plate 226 may have slight vibrations. In the second airflow regulation mode, the driver 21 drives the second vibrating plate 225 to resonate, and the resonant frequency is the natural frequency of the second vibrating plate 225. The first vibrating plate 224 and the third vibrating plate 226 may have slight vibrations. In the third airflow regulation mode, the driver 21 drives the third vibrating plate 226 to resonate, and the resonant frequency is the natural frequency of the third vibrating plate 226. The first vibrating plate 224 and the second vibrating plate 225 may have slight vibrations.

[0100] Since the natural frequencies of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226 are all different, the resonant frequencies of the first airflow adjustment mode, the second airflow adjustment mode, and the third airflow adjustment mode are all different. By controlling the excitation frequency of the driver 21, the excitation frequency of the driver 21 can be switched between the natural frequencies of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226, thereby enabling the airflow regulator 2 to switch between the first airflow adjustment mode, the second airflow adjustment mode, and the third airflow adjustment mode.

[0101] The natural frequency of the first vibrating plate 224 can be lower than the natural frequency of the second vibrating plate 225, and the natural frequency of the second vibrating plate 225 can be lower than the natural frequency of the third vibrating plate 226. For example, the mass of the first vibrating plate 224 is greater than the mass of the second vibrating plate 225, and the mass of the second vibrating plate 225 is greater than the mass of the third vibrating plate 226. If a higher wind speed or a greater degree of wind field adjustment is required, the third airflow adjustment mode can be switched to; if a lower wind speed or a greater degree of wind field adjustment is required, the first airflow adjustment mode can be switched to; if a medium wind speed or a moderate degree of wind field adjustment is required, the second airflow adjustment mode can be switched to.

[0102] According to some embodiments of the present invention, with reference to Figures 1-14All the vibrating plates 22 are arranged in a plane perpendicular to the thickness direction of the vibrating plates 22. Therefore, when the vibrating plates 22 vibrate along their own thickness direction, it is not necessary to consider whether the gaps between the vibrating plates 22 in the thickness direction are sufficient for vibration, facilitating the arrangement of all the vibrating plates 22. Furthermore, this arrangement can reduce the size of the airflow regulating component 2 in the thickness direction of the vibrating plates 22. In addition, since all the vibrating plates 22 are arranged in a plane perpendicular to the thickness direction of the vibrating plates 22, the airflow regulating effect of all the vibrating plates 22 can be effectively increased, improving the airflow regulation effect, thereby enhancing the air delivery effect or the effect of regulating the airflow field.

[0103] Optionally, the distance d between two adjacent vibrating plates 22 is no greater than 10 mm, that is, the distance d between two adjacent vibrating plates 22 ranges from 0 to 10 mm. Two adjacent vibrating plates 22 can be in contact, in which case the distance d between them is 0 (e.g., refer to...). Figures 1-4 as well as Figures 7-10 ); there can also be a gap between two adjacent vibrating plates 22, in which case the distance d between two adjacent vibrating plates 22 is greater than 0 and not greater than 10mm (for example, refer to Figure 5 , Figure 6 , Figures 11-14 By ensuring that the spacing d between two adjacent vibrating plates 22 is no greater than 10mm, the overall size of the airflow regulator 2 can be made smaller, thus reducing the space occupied by the airflow regulator 2.

[0104] Optionally, the distance d between two adjacent vibrating plates 22 is greater than 2mm and not greater than 5mm. This can make the overall size of the airflow regulator 2 smaller, reduce the space occupied by the airflow regulator 2, and better avoid noise generated when adjacent vibrating plates 22 come into contact during vibration.

[0105] In some alternative embodiments of the present invention, reference is made to... Figures 1-14 All vibrating plates 22 are arranged in a plane perpendicular to the thickness direction of the vibrating plates 22, and the roots 221 of all vibrating plates 22 can be connected into a whole by the connecting piece 23. For example, all vibrating plates 22 and connecting pieces 23 can be integrally formed. When the distance d between two adjacent vibrating plates 22 is 0, the above-mentioned multiple vibrating plates 22 can be formed by providing at least one slit on a sheet, that is, a slit is formed between two adjacent vibrating plates 22.

[0106] In some alternative embodiments of the present invention, reference is made to... Figures 1-12All vibrating plates 22 are arranged in a plane perpendicular to the thickness direction of the vibrating plate 22, and all vibrating plates 22 are nested in sequence. Among two adjacent vibrating plates 22, the inner vibrating plate 22 is placed in the clearance notch 223 of the outer vibrating plate 22. Thus, by nesting multiple vibrating plates 22 in the same plane, the arrangement of the vibrating plates 22 can be made compact, reducing the space occupied.

[0107] For example, in some embodiments of the present invention, reference is made to Figures 1-12 All the vibrating plates 22 have different natural frequencies. There are N vibrating plates 22, which are nested sequentially. The driver 21 is located at the root 221 of each vibrating plate 22. Along the direction of nesting from the outside in, the N vibrating plates 22 are the first to the Nth vibrating plates 22. Among them, the first to the (N-1)th vibrating plates 22 are all formed with clearance notches 223. The clearance notch 223 on the Mth vibrating plate 22 can penetrate the root 221 of the Mth vibrating plate 22. The first to the (N-1)th vibrating plates 22 can all be generally U-shaped. The (M+1)th vibrating plate 22 is located within the clearance notch 223 of the Mth vibrating plate 22. The length of the Mth vibrating plate 22 exposed outside the driver 21 is L1, which is the distance between the driver 21 and the end face of the tip 222 of the Mth vibrating plate 22. The airflow regulator 2 has N airflow regulation modes with different resonant frequencies. The N airflow regulation modes are the first to the Nth airflow regulation modes. In the Mth airflow regulation mode, the driver 21 drives the Mth vibrating plate 22 to resonate.

[0108] For example, in Figures 1-6 In the example, there are two vibrating plates 22 with different natural frequencies. The two vibrating plates 22 are nested sequentially, and the driver 21 is located at the root 221 of each vibrating plate 22. Along the direction of nesting from the outside in, the two vibrating plates 22 are a first vibrating plate 224 and a second vibrating plate 225. The first vibrating plate 224 has a clearance notch 223 that penetrates the root 221 of the first vibrating plate 224. The first vibrating plate 224 can be generally U-shaped, and the second vibrating plate 225 is located within the clearance notch 223 of the first vibrating plate 224. The second vibrating plate 225 can contact the inner wall of the clearance notch 223 of the first vibrating plate 224 (e.g., see reference). Figures 1-4 The second vibrating plate 225 may have a gap between itself and the inner wall of the clearance notch 223 of the first vibrating plate 224 (e.g., refer to...). Figures 5-6 The natural frequency of the first vibrating plate 224 can be less than the natural frequency of the second vibrating plate 225. For example, the mass of the first vibrating plate 224 can be greater than the mass of the second vibrating plate 225. The material of the first vibrating plate 224 can be the same as that of the second vibrating plate 225. The thickness of the first vibrating plate 224 can be the same as that of the second vibrating plate 225.

[0109] For example, in Figures 7-12 In the example, there are three vibrating plates 22, each with a different natural frequency. The three vibrating plates 22 are nested sequentially, with the driver 21 located at the root 221 of each vibrating plate 22. Nested sequentially from the outside in, the three vibrating plates 22 are designated as a first vibrating plate 224, a second vibrating plate 225, and a third vibrating plate 226. The first vibrating plate 224 has a clearance notch 223 that penetrates its root 221, and the first vibrating plate 224 is generally U-shaped. The second vibrating plate 225 also has a clearance notch 223 that penetrates its root 221, and the second vibrating plate 225 is generally U-shaped. The second vibrating plate 225 is located within the clearance notch 223 of the first vibrating plate 224, and the third vibrating plate 226 is located within the clearance notch 223 of the second vibrating plate 225. The second vibrating plate 225 can contact the inner wall of the clearance notch 223 of the first vibrating plate 224, and the third vibrating plate 226 can contact the inner wall of the clearance notch 223 of the second vibrating plate 225 (for example, refer to...). Figures 7-10 The second vibrating plate 225 may have a gap with the inner wall of the clearance notch 223 of the first vibrating plate 224, and the third vibrating plate 226 may have a gap with the inner wall of the clearance notch 223 of the second vibrating plate 225 (see, for example, reference). Figures 11-12 ).

[0110] The natural frequency of the first vibrating plate 224 can be less than the natural frequency of the second vibrating plate 225, and the natural frequency of the second vibrating plate 225 can be less than the natural frequency of the third vibrating plate 226. For example, the mass of the first vibrating plate 224 can be greater than the mass of the second vibrating plate 225, and the mass of the second vibrating plate 225 can be greater than the mass of the third vibrating plate 226. The materials of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226 are all the same, and the thicknesses of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226 are all the same.

[0111] In some alternative embodiments of the present invention, reference is made to... Figure 13 and Figure 14 All the vibrating plates 22 are arranged in a plane perpendicular to the thickness direction of the vibrating plate 22, and all the vibrating plates 22 are elongated and arranged sequentially along the width direction of the vibrating plate 22. This arrangement of the vibrating plates 22 makes it easy to process and manufacture.

[0112] Optionally, along the width direction of the vibrating plate 22, the natural frequencies of all the vibrating plates 22 can be increased or decreased sequentially.

[0113] For example, in Figure 13 In the example, there are two vibrating plates 22, both of which are elongated strips. The two vibrating plates 22 are arranged along their width direction and are in the same plane. Along the width direction of the vibrating plates 22, the natural frequencies of the two vibrating plates 22 can increase sequentially. For example, the two vibrating plates 22 are a first vibrating plate 224 and a second vibrating plate 225. The natural frequency of the first vibrating plate 224 is lower than that of the second vibrating plate 225, and the mass of the first vibrating plate 224 is greater than that of the second vibrating plate 225. For example, the materials of the first vibrating plate 224 and the second vibrating plate 225 can be the same, the thickness of the first vibrating plate 224 and the thickness of the second vibrating plate 225 can be the same, the width of the first vibrating plate 224 and the width of the second vibrating plate 225 can be the same, and the length of the first vibrating plate 224 is greater than the length of the second vibrating plate 225.

[0114] For example, in Figure 14 In the example, there are three vibrating plates 22, all of which are elongated strips. The three vibrating plates 22 are arranged along the width direction of the vibrating plate 22 and are arranged in the same plane. Along the width direction of the vibrating plate 22, the natural frequencies of the three vibrating plates 22 can increase sequentially. For example, the three vibrating plates 22 are the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226. The natural frequency of the first vibrating plate 224 is less than the natural frequency of the second vibrating plate 225, and the natural frequency of the second vibrating plate 225 is less than the natural frequency of the third vibrating plate 226. The mass of the first vibrating plate 224 is greater than the mass of the second vibrating plate 225, and the mass of the second vibrating plate 225 is greater than the mass of the third vibrating plate 226. For example, the materials of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226 can all be the same. The thicknesses of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226 can all be the same. The widths of the first vibrating plate 224, the second vibrating plate 225, and the third vibrating plate 226 can all be the same. The length of the first vibrating plate 224 is greater than the length of the second vibrating plate 225, and the length of the second vibrating plate 225 is greater than the length of the third vibrating plate 226.

[0116] At least one airflow regulator 2 is provided, and the airflow regulator 2 is disposed on a fixed bracket 3, which is used to install and fix the airflow regulator 2. The airflow regulator 2 is an airflow regulator 2 according to the first aspect embodiment of the present invention. The root 221 of the vibrating plate 22 of each airflow regulator 2 is connected to the fixed bracket 3 to install and fix the airflow regulator 2 on the fixed bracket 3. When the airflow regulator 2 includes the connecting piece 23 described above, the connecting piece 23 of the airflow regulator 2 can be connected to the fixed bracket 3. In this case, it can be regarded as the root 221 of the vibrating plate 22 being indirectly connected to the fixed bracket 3.

[0117] The airflow regulating component 20 of this invention is easy to process and assemble, and can be applied to various types of air conditioning equipment 100. It has stable and reliable quality and can be mass-produced. Furthermore, the system is simple, low-cost, and has few parts.

[0118] According to the embodiment of the present invention, the airflow regulating component 20, by providing the above-mentioned airflow regulating element 2, can realize the switching between multiple different frequencies since the vibration frequency of the airflow regulating element 2 is adjustable, thereby meeting more air outlet requirements.

These airflow regulators 2 can be arranged in rows, for example, along the left and right directions; they can also be arranged in columns, for example, along the top and bottom directions; or they can be arranged in multiple rows and columns, for example, in both the top and bottom and left and right directions; or they can be arranged irregularly. By setting multiple airflow regulators 2, the air volume can be increased or the regulation effect on the air field can be enhanced to meet the air outlet requirements.

[0120] An air conditioning device 100 according to a third aspect of the present invention includes an airflow regulating component 20 according to the second aspect of the present invention described above.

[0121] Optionally, refer to Figure 16 The airflow regulating component 20 can serve as the air supply component of the air conditioning equipment 100. This eliminates the need for the impeller 50, achieving airflow without impeller 50 drive, thus reducing cost and noise.

[0122] For example, refer to Figure 16The air conditioning device 100 includes a housing 10, a heat exchanger, and the aforementioned airflow regulating component 20. Both the airflow regulating component 20 and the heat exchanger are housed within the housing 10.

The fixing bracket 3 of the airflow regulating component 20 may have a ventilation structure. When the airflow regulating element 2 of the airflow regulating component 20 is working, the vibrating plate 22 of the airflow regulating element 2 reciprocates to induce airflow from the air inlet zone 11 to the air outlet zone 12, forming an airflow path and thus creating an airflow field to deliver air. Furthermore, the airflow speed can be adjusted by controlling the voltage frequency of the alternating voltage applied to the driver 21 of the airflow regulating element 2.

[0124] For example, refer to Figure 17 The air conditioning equipment 100 includes a housing 10, a fan, a heat exchanger, and the aforementioned airflow regulating component 20. The fan, airflow regulating component 20, and heat exchanger are all housed within the housing 10. The fan includes a fan wheel 50 and a motor for driving the fan wheel 50 to rotate.

A water collection tray 40 is provided at the bottom of the heat exchanger. An air inlet area 11 and an air outlet area 12 are formed on the housing 10. Both the air inlet area 11 and the air outlet area 12 can be grid-like; for example, the air inlet area 11 can be formed at the rear of the housing 10, and the air outlet area 12 can be formed at the front of the housing 10. The fixing bracket 3 of the airflow regulating component 20 can have a ventilation structure. When the airflow regulating component 20 is working, the vibrating plate 22 of the airflow regulating component 2 reciprocates and turbulently to regulate the airflow generated by the fan wheel 50. Furthermore, the effect of regulating the wind field is adjusted by controlling the voltage frequency of the alternating voltage applied to the driver 21 of the airflow regulator 2.

[0125] According to an embodiment of the present invention, the air conditioning device 100, by providing the airflow regulating component 20, can switch between multiple different frequencies since the vibration frequency of the airflow regulating component 20 is adjustable, thereby meeting more air outlet requirements.

[0126] According to some embodiments of the present invention, the air conditioning device 100 further includes an airflow processing component 30 for processing airflow, the airflow processing component 30 including at least one of a temperature regulating device for regulating the temperature of the airflow, a humidity regulating device for regulating humidity, a purification device for purifying, and an odor regulating device for regulating odor.
