Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an atomizer. Background Art

[0002] With the popularity of handheld nebulizers, more and more patients choose medical nebulizers as a treatment tool for respiratory diseases. Nebulization treatment uses a nebulizer to generate ultrasonic waves to turn liquid drugs into fine atomized particles. The diameter of the atomized particles is small, so they are easily absorbed by the patient's lungs, and the treatment effect is very significant. However, the particle sizes of different drugs after atomization are different. When the atomized drug particles used are too large, the mesh of the nebulizer is easily blocked, resulting in poor atomization effect and reduced atomization volume. The method for solving mesh blockage in the prior art is usually to replace the drug in the nebulizer with clean water and turn on the atomization vibration function, and use the vibration of the nebulizer itself for self-cleaning. However, the cleaning strength of this cleaning method is limited, and the drug particles with strong adhesion are difficult to fall off and will still block the mesh. The self-cleaning effect of the nebulizer is poor, affecting the use, and the user can only replace a new atomizer head. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor self-cleaning effect of the atomizer in the prior art, thereby providing an atomizer with good self-cleaning effect.

[0004] In order to solve the above technical problems, the present invention provides an atomizer, comprising:

[0005] A first vibration plate, wherein a mesh area is provided on the first vibration plate;

[0006] A second vibration plate is spaced apart from the first vibration plate, and a closed cavity is formed between the second vibration plate and the first vibration plate;

[0007] A first vibration part, disposed on the first vibration sheet, fixedly connected to the first vibration sheet, and adapted to drive the first vibration sheet to vibrate;

[0008] The second vibration part is arranged on the second vibration plate and fixedly connected to the second vibration plate. The second vibration part is suitable for being selectively turned on to drive the second vibration plate to vibrate. The vibration of the second vibration plate is suitable for resonating with the first vibration plate.

[0009] Optionally, the atomizer further includes: a connecting portion, which is connected to the edges of the first vibration plate and the second vibration plate at the same time, and is suitable for forming a closed cavity together with the first vibration plate and the second vibration plate.

[0013] Optionally, the first vibration part and the second vibration part are piezoelectric ceramics.

[0014] Optionally, the mesh area is arranged at a center position of the first vibration plate.

[0015] Optionally, the first vibration part is in the shape of a ring, the center of which coincides with the center point of the first vibration plate, and is arranged around the mesh area.

[0016] Optionally, the second vibration part is in the shape of a ring, and the center of the ring coincides with the center point of the second vibration plate.

[0017] Optionally, the first vibration plate and the second vibration plate are made of metal.

At the same time, the second vibrating part is selectively turned on by setting a second vibrating part, and drives the second vibrating plate to vibrate when turned on, so as to resonate with the first vibrating plate through the second vibrating plate. Compared with the traditional nebulizer that is self-cleaned only by the vibration of the first vibrating plate, the vibration amplitude and intensity of the first vibrating plate are increased by resonance in this embodiment, so that the drug particles that are difficult to clean and stick to the mesh area are vibrated off, the self-cleaning effect is enhanced, the problem of mesh blockage is effectively improved, and a better atomization effect is achieved. At the same time, the number of times the atomizer head is replaced is reduced, saving money. In addition, the second vibrating part is selectively turned on, so the second vibrating part can be turned on or off according to whether cleaning is needed, which is convenient to operate and free to choose, which is conducive to improving user experience.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Combination Figure 1-Figure 2 As shown, the atomizer provided in this embodiment includes:

[0035] A first vibration plate 1, wherein a mesh area 11 is provided on the first vibration plate 1;

[0036] A second vibration plate 2 is spaced apart from the first vibration plate 1, and a closed cavity is formed between the second vibration plate 2 and the first vibration plate 1;

[0037] A first vibration part 3 is disposed on the first vibration sheet 1, fixedly connected to the first vibration sheet 1, and suitable for driving the first vibration sheet 1 to vibrate;

[0038] The second vibration part 4 is disposed on the second vibration plate 2 and fixedly connected to the second vibration plate 2 . The second vibration part 4 is suitable for being selectively turned on to drive the second vibration plate 2 to vibrate. The vibration of the second vibration plate 2 is suitable for resonating with the first vibration plate 1 .

[0039] It should be noted that during the use of the nebulizer, the liquid medicine filled in the cavity is atomized by the vibration of the first vibrating plate 1, and the liquid in contact with the mesh area 11 of the first vibrating plate 1 is sprayed out through the mesh holes on the mesh area 11. As the number of uses increases, the mesh area 11 is gradually attached with difficult-to-clean medicine particles that clog the mesh holes. In order to ensure that the atomization effect is not affected, it is necessary to clean it. At this time, clean water is filled into the cavity, and the first vibrating part 3 and the second vibrating part 4 are turned on at the same time, driving the first vibrating plate 1 and the second vibrating plate 2 to generate ultrasonic vibrations at the same time. The ultrasonic wave generated by the second vibrating plate 2 is transmitted to the first vibrating plate 1 through the liquid, and the first vibrating plate 1 and the second vibrating plate 2 are adjusted to resonate, the amplitude of the first vibrating plate 1 is increased, and the vibration intensity is enhanced, thereby increasing the cleaning force, and the medicine particles that are difficult to clean in the mesh area 11 can be vibrated off, and then the fallen particles are poured out together with the water in the cavity. Multiple cleanings can be performed as needed to achieve the cleaning of the mesh area 11.

[0040] The nebulizer provided in the present embodiment drives the first vibration plate 1 to vibrate by setting the first vibration part 3, so as to realize atomization of the liquid in contact with the mesh area 11 on the first vibration plate 1. At the same time, the second vibration part 4 is selectively opened and drives the second vibration plate 2 to vibrate when opened, so as to resonate with the first vibration plate 1 through the second vibration plate 2. Compared with the traditional nebulizer which is self-cleaned only by the vibration of the first vibration plate 1, the vibration amplitude and intensity of the first vibration plate 1 are increased by resonance in the present embodiment, so as to realize vibration and fall off of the drug particles which are difficult to clean and stick to the mesh area 11, enhance the self-cleaning effect, effectively improve the problem of mesh blockage, achieve better atomization effect, and also reduce the number of times of replacing the atomizer head, saving money. Moreover, the second vibration part 4 is selectively opened, so the second vibration part 4 can be turned on or off according to whether cleaning is needed, which is convenient to operate and free to choose, and is conducive to improving user experience.

[0041] Specifically, the atomizer further includes: a connecting portion 5 , which is connected to the edges of the first vibration plate 1 and the second vibration plate 2 at the same time, and is suitable for forming a closed cavity together with the first vibration plate 1 and the second vibration plate 2 .

[0042] The atomizer provided in this embodiment connects the first vibration plate 1 and the second vibration plate 2 by setting the connecting portion 5 to be connected to the edges of the first vibration plate 1 and the second vibration plate 2 at the same time, thereby forming a closed cavity suitable for containing liquid, which is convenient for containing and carrying liquid.

[0043] Specifically, the connecting portion 5 is provided with an opening, and the opening is suitable for being selectively opened and suitable for introducing or exporting the liquid in the cavity.

[0044] It should be noted that the opening is suitable for selective opening, which means that when liquid needs to be added into or poured out of the cavity, the opening is opened, and when the atomizer is in operation or not in use, the opening is closed.

[0045] Specifically, the second vibration sheet 2 is detachably connected to the connecting portion 5 .

[0046] It should be noted that when liquid needs to be added into or poured out of the cavity, the second vibration plate 2 is disassembled; and when the atomizer is in operation or not in use, the second vibration plate 2 is buckled with the connecting portion 5.

[0047] The atomizer provided in this embodiment is provided with a selectively opened opening on the connecting portion 5. When it is necessary to add liquid to the cavity or pour out the liquid in the cavity, the opening is opened to import or export the liquid. When the atomizer is working, the opening is closed to prevent the liquid in the cavity from flowing out. The structure is simple and the operation is convenient. Alternatively, the second vibration plate 2 is provided to be detachably connected to the connecting portion 5. When it is necessary to add liquid to the cavity or pour out the liquid in the cavity or when the ultrasonic vibration function is not used, the second vibration plate 2 is removed to add liquid to the cavity or pour out the liquid in the cavity. When the atomizer is working, the second vibration plate 2 is buckled with the connecting portion 5 to close the cavity. The structure is simple and the operation is convenient.

[0048] Specifically, the atomizer further includes: a control board, which is electrically connected to the first vibration part 3 and the second vibration part 4 and is suitable for sending an electrical signal to the first vibration part 3 and / or the second vibration part 4 .

[0049] Optionally, the atomizer includes an atomization function key and a self-cleaning function key.

[0050] It should be noted that, when the atomization function key is pressed, the control board sends an electrical signal to the first vibration part 3, and the first vibration part 3 vibrates after receiving the electrical signal, thereby driving the first vibration plate 1 to vibrate, thereby realizing the atomization of the liquid medicine; when the self-cleaning function key is pressed, the control board sends an electrical signal to the first vibration part 3 and the second vibration part 4 at the same time, and the first vibration part 3 and the second vibration part 4 vibrate after receiving the electrical signal, thereby driving the first vibration plate 1 and the second vibration plate 2 to vibrate at the same time, and the two signals sent by the control board to the first vibration part 3 and the second vibration part 4 have the same frequency, therefore, the first vibration plate 1 resonates with the second vibration plate 2, thereby enhancing the cleaning effect of the first vibration plate 1.

[0051] Optionally, the electrical signal sent by the control board to the second vibration part 4 includes a plurality of gears of different sizes.

[0052] It should be noted that, according to the principle of signal superposition, if the frequencies of two signals are the same, when the amplitude of one of the signals increases, the total resonance amplitude will also increase accordingly. Therefore, the increase in the amplitude of the second vibration part 4 will also increase the resonance amplitude. Therefore, the resonance amplitude can be adjusted by adjusting the size of the electrical signal sent by the control board to the second vibration part 4. The corresponding gear can be selected according to the user experience and needs to improve the user experience.

[0053] The atomizer provided in this embodiment sends an electrical signal to the first vibration part 3 and / or the second vibration part 4 by arranging the control board to be electrically connected to the first vibration part 3 and the second vibration part 4, thereby controlling the opening or closing of the first vibration part 3 and / or the second vibration part 4, which is beneficial to improving automation and enhancing user experience.

[0054] Specifically, the first vibration part 3 and the second vibration part 4 are piezoelectric ceramics.

[0055] The atomizer provided in this embodiment, by setting the first vibration part 3 and the second vibration part 4 to be piezoelectric ceramics, utilizes the piezoelectric characteristics of piezoelectric ceramics to realize mutual conversion between electrical energy and mechanical energy, realizes conversion of electrical signals into vibrations, has high reliability, and is conducive to improving product quality.

[0056] Specifically, the mesh area 11 is arranged at the center of the first vibration plate 1 .

[0057] Optionally, the mesh area 11 is processed by laser processing.

[0058] Specifically, the first vibration part 3 is in the shape of a ring, the center of which coincides with the center point of the first vibration plate 1 , and is disposed around the mesh area 11 .

[0059] The atomizer provided in this embodiment arranges the mesh area 11 at the center position of the first vibration plate 1, and the first vibration part 3 is in a circular ring shape and is arranged around the mesh area 11, so that when the first vibration part 3 drives the first vibration plate 1 to vibrate, the mesh area 11 is located in the area with the largest vibration amplitude on the first vibration plate 1, thereby maximally atomizing the liquid in contact with the mesh area 11, ensuring a better atomization effect and improving the user experience.

[0060] Specifically, the second vibration part 4 is in the shape of a ring, and the center of the ring coincides with the center point of the second vibration plate 2 .

[0061] Specifically, the first vibration plate 1 and the second vibration plate 2 are made of metal.

[0062] Optionally, the connecting portion 5 is made of metal.

[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
