Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, specifically to an ultrasonic atomizer. Background Technology

[0002] Ultrasonic atomization is a technology that uses high-frequency sound wave energy to transform liquids into tiny droplets. Its core principle is to convert electrical energy into high-frequency mechanical vibrations (typically exceeding 1 MHz) using a piezoelectric transducer. When these vibrations are transmitted into the liquid, they create a cavitation effect at the liquid surface, forming tiny capillary waves. When the energy at the wave crest exceeds the liquid's surface tension, the droplets detach from the wave crest, forming uniform aerosol particles with a diameter of only 1-5 micrometers. This technology achieves low-temperature atomization without heating, preserving the original properties of the liquid, and is widely used in medical nebulized drug delivery.

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] Existing ultrasonic nebulizers, because the medicine cup can only hold one type of medicine, require that when two medicines need to be used consecutively, the machine must be stopped, disassembled and the second medicine added after the first medicine is completely nebulized, and then reinstalled and restarted. This process not only seriously interrupts the continuity of treatment, prolongs the total treatment time, and reduces treatment efficiency, but also brings a cumbersome operational burden to the operator.

[0005] In addition, once the ultrasonic nebulizer starts working, the medicine cup is in a closed nebulization state. If additional medication is needed during treatment, nebulization must be stopped and the device opened before adding medication. This interrupts the treatment process again and cannot meet the needs of long-term treatments or treatments that require dosage adjustments. It lacks flexibility and convenience.

[0006] Therefore, this solution provides an ultrasonic atomizer to solve the above problems. Utility Model Content

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] According to the appendix Figure 1 - Figure 5 As shown, this utility model provides an ultrasonic nebulizer, including a nebulizing mechanism 1, a top cover mechanism 2 is provided above the nebulizing mechanism 1, a medicine holding mechanism 3 is provided below the top cover mechanism 2, and two symmetrical medicine replenishing mechanisms 4 are provided inside the top cover mechanism 2.

[0033] The atomizing mechanism 1 includes an atomizing body 11 and an atomizing groove 14 opened at the top of the atomizing body 11;

[0034] The top cover mechanism 2 includes an atomizing cover 21 that is snapped onto the periphery of the atomizing groove 14 and two symmetrical limiting tubes 23 that are fixedly connected to the inner side of the atomizing cover 21;

[0035] The medicine dispensing mechanism 3 includes a medicine dispensing cup 31 placed inside the atomizing tank 14 and a semi-circular partition 35 in the middle of the medicine dispensing cup 31;

[0036] The supplement mechanism 4 includes an addition tube 41 rotatably connected inside the limiting tube 23 and a one-way plate 45 at the bottom of the addition tube 41;

[0037] The atomizing tank 14 is the atomizing mounting cavity of the atomizing body 11. The ultrasonic oscillating head 15 inside is used to generate ultrasonic vibrations to work with the convex oscillating membrane 32 to atomize the medicine in the dispensing cup 31. The atomizing tank 14 is also equipped with a heating device to heat the water in the atomizing tank 14, thereby heating the medicine in the water.

[0038] In a further embodiment, a partition plate 33 is fixedly connected inside the dispensing cup 31. The partition plate 33 has a groove 34. A semi-circular partition 35 is located inside the groove 34. A connecting shaft 36 is fixedly connected to the top of the semi-circular partition 35. A connecting wheel 37 is fixedly connected to the top of the connecting shaft 36. The outer periphery of the connecting wheel 37 contacts the outer periphery of the adding tube 41.

[0039] In this embodiment, the connecting shaft 36 is rotatably connected to the center of the partition plate 33, thereby allowing the connecting wheel 37 at its top to rotate stably.

[0040] In a further embodiment, a convex oscillating diaphragm 32 is installed at the bottom of the dispensing cup 31, and an ultrasonic oscillating head 15 and a liquid leveling device 16 are installed inside the atomizing tank 14, with the convex oscillating diaphragm 32 in contact with the ultrasonic oscillating head 15.

[0041] In this embodiment, the liquid level component 16 is used to indicate the highest liquid level to the user when adding water to the atomizing tank 14; the top cover mechanism 2, the medicine holding mechanism 3, and the medicine replenishment mechanism 4 are all made of transparent material.

[0042] In a further embodiment, a magnetic ring 42 is fixedly connected to the periphery of the adding tube 41. The magnetic ring 42 cooperates with the bottom surface of the limiting tube 23. A spinal tube 43 is fixedly connected to the bottom of the adding tube 41. One side of the one-way plate 45 is rotatably connected to the bottom of the spinal tube 43.

[0043] In this embodiment, a magnet is embedded above the magnetic ring 42, and a magnet is also embedded on the bottom surface of the limiting tube 23. Thus, during installation, the adding tube 41 can be inserted from the inside of the atomizing cover 21, which facilitates disassembly and cleaning.

[0044] In a further embodiment, receiving convex shafts 44 are fixedly connected to both sides of the tube 41, connecting convex shafts 47 are fixedly connected to both sides of the one-way plate 45, plastic tension springs 48 are hung on the outside of the receiving convex shafts 44 and connecting convex shafts 47, and a sealing gasket 46 is fixedly connected to one side of the one-way plate 45, the sealing gasket 46 fitting the inner side of the spinal canal 43.

[0045] In this embodiment, the spinal canal 43 has an ear plate shaft on one side, which can be aligned with the notch on one side of the one-way plate 45 to allow them to rotate and connect; the plastic tension spring 48 is an S-shaped elastic sheet made of plastic, which allows the one-way plate 45 to always fit against the bottom of the spinal canal 43, thereby forming a one-way tube.

[0046] In a further embodiment, a control knob 12 is provided on one side of the atomizing body 11, and a fan 13 is provided on the top of the atomizing body 11, with the output end of the fan 13 connected to one side of the atomizing cover 21.

[0047] In this embodiment, the control knob 12 can control the start of the ultrasonic oscillating head 15, the heating device and temperature located in the atomizing tank 14, and can also control the atomization time and the size of the atomization; the fan 13 is used to inject airflow into the inside of the atomizing cover 21, and there is a knob on the top of the fan 13 to control the air volume.

[0048] In a further embodiment, an atomizing connector 22 is provided above the atomizing cover 21.

[0049] In this embodiment, the atomizing connector 22 is used to connect to the mouthpiece or nasal mask via a hose or corrugated tube, so that the liquid medicine can be delivered to the patient's mouth and nose.

[0050] The working principle of this utility model is as follows:

[0051] When using the nebulizer 1, first turn on the power and place two or one type of medicine inside the medicine cup 31. Then, inject warm water into the nebulizer tank 14. At this time, align the convex vibrating membrane 32 at the bottom of the medicine cup 31 with the ultrasonic vibrating head 15. Finally, close the top cover mechanism 2 and turn on the fan 13 and the ultrasonic vibrating head 15 through the switch of the nebulizer body 11. The operation of the ultrasonic vibrating head 15 will cause the convex vibrating membrane 32 to atomize the medicine upward, while the operation of the fan 13 will generate airflow to spray the atomized medicine from the nebulizer connector 22 and deliver it to the patient's mouth through the corrugated tube and mouthpiece for treatment.

[0052] If a certain medication is found to be insufficient during the nebulization process, the corresponding addition tube 41 can be selected, and the medication to be added can be poured into the medicine cup 31 through the addition tube 41. During the pouring process, the medication will push the one-way plate 45, causing the plastic spring 48 to be stretched. After the medication passes through, the rebound of the plastic spring 48 will make the one-way plate 45 fit tightly against the bottom of the spinal tube 43. Thus, insufficient medication can be added in real time during the nebulization process.

[0053] In addition, when two kinds of medicine are placed in the medicine cup 31 and on both sides of the partition 33, after the medicine on one side of the partition 33 is atomized, one of the adding tubes 41 can be rotated to make the outer periphery of the adding tube 41 rub against the connecting wheel 37, causing the connecting wheel 37 to drive the connecting shaft 36 and the semi-arc partition 35 to rotate. This allows the medicine on the other side of the partition 33 to be immersed above the convex oscillating membrane 32. Thus, the two kinds of medicine can be atomized alternately without disassembly. At the same time, when the two kinds of medicine need to be atomized together, only the semi-arc partition 35 needs to be rotated ninety degrees.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
