Description

Technical Field

[0001] This utility model relates to the field of nebulizer technology, specifically a portable ultrasonic nebulizer for administering viscous medicine with adjustable nebulization dosage. Background Technology

[0002] An ultrasonic nebulizer is a nebulization device used in medical applications. Its basic principle is as follows: the oscillation signal from the main circuit board is amplified by a high-power transistor and transmitted to the ultrasonic chip. The ultrasonic chip converts electrical energy into ultrasonic energy. At room temperature, the ultrasonic energy can atomize water-soluble drugs into tiny mist particles of 1µm to 5µm. Using water as a medium, the water-soluble drug solution is sprayed into a mist using ultrasonic directional pressure.

[0003] Chinese patent CN220386955U discloses an atomizing plate module and atomizing device that can atomize highly viscous or macromolecular liquids. It uses an included angle to break the surface tension formed by the highly viscous or macromolecular liquid located in the first opening, further preventing the highly viscous or macromolecular liquid from clogging in the first opening, and ensuring that the highly viscous or macromolecular liquid can drip through the first opening onto the vibrating metal plate for atomization.

[0004] The above solutions use angled atomizing plates suitable for nebulizing viscous medications. However, since the spray range of these atomizing plates is mostly not adjustable after being powered on, it is difficult for users to adjust the nebulized dosage according to their needs. Therefore, we provide a portable ultrasonic nebulizer for viscous medications with adjustable nebulized dosage to solve these problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a portable ultrasonic nebulizer for administering viscous medicines with adjustable nebulization dosage.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a portable ultrasonic nebulizer for administering viscous medicine with adjustable nebulization dosage, comprising:

[0009] The drug delivery device body has a partition chamber fixedly connected inside it, and an atomizing chamber is formed inside the drug delivery device body through the partition chamber. An atomizing plate is installed inside the partition chamber. A through groove is opened on the drug delivery device body, and an exhaust pipe is slidably connected inside the through groove.

[0010] A rotating seat is rotatably connected to the main body of the drug delivery device, and the rotating seat is connected to the atomizing chamber through a mist exhaust pipe. The rotating seat is provided with a spray assembly arranged in a circumferential array.

[0011] An elastic support assembly is installed on the exhaust pipe to limit its movement on the rotating seat.

[0012] The push rod is slidably connected to the rotating seat, and the push rod pushes the exhaust pipe to release the exhaust pipe from the upper limit of the rotating seat.

[0013] Furthermore, the spray assembly includes a connecting pipe fixedly connected to the rotating seat, and a mesh screen is embedded in the connecting pipe.

[0014] Furthermore, the elastic support assembly includes a linkage block fixedly connected to the mist exhaust pipe, a guide rod slidably connected to the linkage block, one end of the guide rod being fixedly connected to the drug delivery device body, and a limiting ring fixedly connected to the mist exhaust pipe, with the limiting ring located inside the atomization chamber.

[0015] Furthermore, a spring is sleeved on the guide rod, with the two ends of the spring abutting against the drug delivery device body and the linkage block, respectively.

[0016] Furthermore, a sealing groove is provided on the rotating seat, one end of the mist exhaust pipe is inserted into the sealing groove, and a sealing ring is installed on the mist exhaust pipe, and the sealing ring matches the sealing groove.

[0017] Furthermore, one end of the push rod is fixedly connected to the linkage block, and the other end of the push rod passes through the rotating seat and is fixedly connected to a handheld component.

[0018] Furthermore, the outer surface of the rotating base is provided with anti-slip texture.

[0019] (iii) Beneficial effects:

[0020] Compared with existing technologies, this portable ultrasonic nebulizer for administering viscous medicines with adjustable atomization dosage has the following advantages:

[0021] I. This utility model has multiple connecting tubes on the rotating base each inlaid with a filter screen of different aperture and number. By simply rotating the rotating base, different filter screens can be selected, and the atomization dosage can be adjusted according to one's own needs, thereby achieving precise control of the atomization dosage. This solves the problem of the non-adjustable spray range of traditional atomizers and improves the flexibility and personalized experience of use.

[0022] Second, this utility model ensures the sealing between the exhaust pipe and the connecting pipe through the cooperation of the elastic support component and the sealing ring, preventing leakage of atomized liquid. The design of the push rod and the hand handle makes it more convenient for users to switch spray components. Simply push the hand handle to release the limit of the exhaust pipe. After rotating the seat to switch, release the hand handle, and the spring will automatically reset the exhaust pipe and reseal it. This not only improves the sealing performance of the equipment, but also simplifies the operation process and improves the user experience. Attached Figure Description

[0027] 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.

[0028] like Figure 1-3 As shown, this utility model provides a technical solution: a portable ultrasonic nebulizer for dispensing viscous medicine with adjustable atomization dosage, comprising a main body 1, a partition chamber 2 fixedly connected inside the main body 1, and an atomization chamber formed inside the main body 1 through the partition chamber 2, an atomizing plate 3 installed inside the partition chamber 2, the atomizing plate 3 having an existing structure, the atomizing plate 3 being designed with an angle that can disrupt the liquid surface, enabling the atomizing plate 3 to perform ultrasonic atomization of the viscous medicine, and the generated atomized liquid in the atomization chamber, the main body 1 having a through groove 7, and a mist exhaust pipe 8 slidably connected inside the through groove 7, the mist exhaust pipe 8 being a hollow tubular structure.

[0029] The rotating seat 4 is rotatably connected to the main body 1 of the drug delivery device, and the rotating seat 4 is connected to the atomizing chamber through the mist exhaust pipe 8. The outer surface of the rotating seat 4 is provided with anti-slip texture, and the rotating seat 4 is provided with a spray assembly arranged in a circumferential array. The anti-slip texture makes it convenient for the user to rotate the rotating seat 4, thereby aligning the different spray assemblies with the mist exhaust pipe 8.

[0030] The spray assembly includes a connecting pipe 5 fixedly connected to the rotating seat 4, and a mesh 6 is embedded in the connecting pipe 5. There are at least two connecting pipes 5, and the number and size of the holes on each mesh 6 are different, so that different atomization doses can be achieved by using mesh 6 of different specifications.

[0031] An elastic support assembly is provided on the mist exhaust pipe 8 to limit the position of the mist exhaust pipe 8 on the rotating seat 4. The elastic support assembly includes a linkage block 12 fixedly connected to the mist exhaust pipe 8, a guide rod 13 slidably connected to the linkage block 12, one end of the guide rod 13 fixedly connected to the drug delivery device body 1, and a limiting ring 9 fixedly connected to the mist exhaust pipe 8. The limiting ring 9 is located inside the atomization chamber. The limiting ring 9 is used to limit the position of the mist exhaust pipe 8 to prevent the mist exhaust pipe 8 from sliding out of the atomization chamber as a whole.

[0032] A spring 14 is sleeved on the guide rod 13. The two ends of the spring 14 abut against the main body 1 of the drug delivery device and the linkage block 12 respectively. The spring 14 supports the linkage block 12 by its own elasticity, thereby applying a thrust from the rotating seat 4 to the mist exhaust pipe 8, so that the mist exhaust pipe 8 can abut against the inner wall of the rotating seat 4.

[0033] A sealing groove 15 is provided on the rotating seat 4. One end of the mist exhaust pipe 8 is inserted into the sealing groove 15. A sealing ring 16 is installed on the mist exhaust pipe 8, and the sealing ring 16 matches the sealing groove 15.

[0034] By utilizing the elasticity of the spring 14, the sealing ring 16 on the mist exhaust pipe 8 can be inserted into the sealing groove 15, so that the mist outlet end of the mist exhaust pipe 8 is aligned with the mesh plate 6. The sealing ring 16 can also improve the sealing between the mist exhaust pipe 8 and the connecting pipe 5.

[0035] The push rod 10 is slidably connected to the rotating seat 4, and the push rod 10 pushes the exhaust pipe 8 to release the exhaust pipe 8 from the upper limit of the rotating seat 4. One end of the push rod 10 is fixedly connected to the linkage block 12, and the other end of the push rod 10 passes through the rotating seat 4 and is fixedly connected to the handpiece 11.

[0036] When rotating the rotating seat 4, the push rod 10 can be pushed by the handpiece 11, and one end of the mist exhaust pipe 8 can be pushed out from the inside of the sealing groove 15, thereby releasing the limit of the rotating seat 4, and rotating the rotating seat 4 so that the required mesh plate 6 is rotated to the position opposite to the mist exhaust pipe 8. Then, the handpiece 11 is released, and the elasticity of the spring 14 is used to quickly reset the mist exhaust pipe 8.
