Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of atomizers, and in particular to a high-pressure dual-cylinder structure for use in atomizers. Background Technology
[0002] A nebulizer is a device that physically transforms liquid substances into tiny droplets or aerosols, and it is widely used in medical, industrial, and humidification fields. In the medical field, nebulizers use specific technologies to break down liquid drugs or solutions into tiny particles or aerosols with a diameter of approximately 1-5 micrometers, allowing them to be inhaled directly and act on the respiratory tract or lungs. Its core function is to improve drug utilization and reduce systemic side effects, making it particularly suitable for local treatment of respiratory diseases.
[0003] Based on their different technical principles, nebulizers can be divided into three types: compressor / jet nebulizers, ultrasonic nebulizers, and vibrating mesh / screen nebulizers. Among these, the most commonly used is the compressor nebulizer. Its overall structure typically includes: a power system, an air delivery system, a core nebulization component, a patient interface, and auxiliary structures. Generally, the design of compressor nebulizers balances functionality and safety. Powered by a compressor unit, it achieves efficient drug nebulization through the Venturi effect. With the addition of filtration, flow regulation, and patient fitting components, it has become the preferred device for treating lower respiratory tract diseases. Its residue-free, low-noise, and easy-to-maintain characteristics make it particularly suitable for long-term home and clinical use.
[0004] Based on this, Chinese patent CN109011050B discloses an air-compressed atomizer, which includes a housing, a rotating cylinder coaxially arranged inside a conical cylinder, an air compressor above the rotating cylinder, and an air compressor outlet connected to an impact plate inside the rotating cylinder via a jet pipe, with the impact plate located near the bottom plate of the rotating cylinder. The jet pipe enters the rotating cylinder from the top, and a medicine tank is also provided inside the housing. The medicine tank is connected to the jet pipe via a delivery pipe, and an anti-backflow device is provided inside the jet pipe. Several jet holes are opened around the side wall of the upper end of the rotating cylinder, and a stirring rod is provided near the outlet of the water pipe. In this type of air compressor, compressed air carrying medicine impacts the impact plate at high speed to form an atomized spray. The spray forms a vortex inside the rotating cylinder as the cylinder rotates, and the centrifugal force of the vortex can throw the liquid medicine in the spray onto the cylinder wall. The medicine flows down the cylinder wall and flows into the conical cylinder through the hole at the bottom of the rotating cylinder.
[0005] However, the aforementioned air-compression nebulizers still suffer from technical problems such as insufficient air pressure or airflow. Specifically, existing air-compression nebulizers typically use an oil-free piston compressor as their core power source. This compressor utilizes mechanical energy to compress ambient air into a high-pressure airflow for output. Since no cooling water is required during air compression, it generally offers advantages such as low operating noise and low maintenance costs. However, in some applications, users may require the oil-free piston compressor to output higher air pressure and flow rate to convert liquid medication in the nebulizer cup into inhalable micro-droplets. The flow rate and pressure of the compressed air significantly affect the atomization rate and particle size; generally, the higher the compressed air pressure and flow rate, the shorter the atomization time required for the liquid medication. Utility Model Content

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] Please refer to the following: Figures 1 to 3 This utility model discloses a high-pressure dual-cylinder structure for an atomizer, comprising: a support frame 1, a drive motor 2, a drive shaft 3, an eccentric wheel structure 4, a connecting rod structure 5, a piston structure 6, and a piston cylinder body 7. The drive motor 2 is mounted on the support frame 1 and is drivenly connected to the drive shaft 3. The eccentric wheel structure 4 is movably disposed within the support frame 1, and the drive shaft 3 is drively connected to the eccentric wheel structure 4. The connecting rod structure 5 is connected to the eccentric wheel structure 4, and the two piston structures 6 are respectively connected to the two ends of the eccentric wheel structure 4. The two piston cylinder bodies 7 are disposed opposite to each other at the two ends of the support frame 1, and each piston structure 6 is movably fitted into one piston cylinder body 7.
[0028] Specifically, when the high-pressure dual-cylinder structure of this utility model applied to an atomizer is in operation, the drive motor 2 can drive the drive shaft 3 to rotate, and then the drive shaft 3 drives the eccentric wheel structure 4 to rotate. The rotation of the eccentric wheel structure 4 can drive the connecting rod structure 5 to move back and forth left and right within the support frame 1. Then, the connecting rod structure 5 drives the two piston structures 6 located at its left and right ends to move simultaneously. When the two pistons move in the same direction, the volume changes of the sealed cavities formed by the two piston structures 6, which are movably sleeved in the two corresponding piston cylinder bodies 7, in opposite directions, so that the flow direction of the gas flowing through their respective air outlets in the two piston cylinder bodies 7 is opposite. For example, when the eccentric wheel structure 4 drives the connecting rod structure 5 to move to the left, the volume of the sealed cavity formed by the left piston structure 6 and the piston cylinder body 7 it sleeves decreases and outputs compressed air. At this time, the volume of the sealed cavity formed by the right piston structure 6 and the piston cylinder body 7 it sleeves increases and introduces air. Similarly, when the eccentric rotary wheel structure 4 drives the connecting rod structure 5 to move to the right, the volume of the sealed cavity formed by the right piston structure 6 and the piston cylinder body 7 it is fitted with decreases, thus outputting compressed air. At this time, the volume of the sealed cavity formed by the left piston structure 6 and the piston cylinder body 7 it is fitted with increases, thus introducing air. That is, the high-pressure dual-cylinder structure of this utility model applied to an atomizer can simultaneously drive two sets of piston devices to do work, doubling the power utilization efficiency; thus, it can output higher pressure and greater flow rate of compressed air per unit time; thereby solving the technical problem of how to improve the air compression efficiency of the piston compression mechanism.
[0029] Based on the aforementioned structure, this utility model's high-pressure dual-cylinder structure for nebulizers can have three different working modes: Working Mode 1: This utility model can have two separate air sources for independent air output, simultaneously providing two air sources and two nebulizing cups, enabling multi-purpose use. For example, when multiple patients in a family are nebulizing simultaneously, this saves on the need for a single machine, breaking the traditional model that requires multiple nebulizers. This saves on consumer operating costs and demonstrates energy-saving and environmentally friendly economic benefits. Working Mode 2: This utility model can have two sets of piston devices working in parallel, thus meeting the high air supply requirements of devices with large nebulization volumes. Working Mode 3: This utility model can have two sets of piston devices working in series. When connected in series, the pressure of the compressed air output by this utility model is greater. This working mode allows it to be applied to more types of devices, such as suction devices and negative pressure devices, in addition to nebulizers.
[0030] Furthermore, the eccentric wheel structure 4 includes a wheel body 401, a bushing 402, and an eccentric shaft 403. The bushing 402 is disposed on the wheel body 401 and is connected to the drive shaft 3. The eccentric shaft 403 is disposed below the wheel body 401 and is connected to the connecting rod structure 5. Specifically, when the drive motor 2 drives the drive shaft 3 to rotate, the drive shaft 3 can drive the bushing 402, causing the wheel body 401 to rotate along with the drive shaft 3. More specifically, the bushing 402 is disposed in the middle of the wheel body 401, that is, the bushing 402, the wheel body 401 and the drive shaft 3 are disposed on the same central axis; while the eccentric shaft 403 is disposed off the central axis of the wheel body 401. Typically, the eccentric shaft 403 can be disposed off the central axis of the wheel body 401 and disposed on one side; thus, when the wheel body 401 rotates, the eccentric shaft 403 can be eccentrically rotated at the same time.
[0031] Furthermore, the eccentric wheel structure 4 is also provided with a plurality of counterweight structures 404, which are evenly distributed around the bushing 402 on the wheel body 401. Each counterweight structure 404 is provided with a screw hole (not shown in the figure). Specifically, the counterweight structure 404 can be threadedly connected to an external counterweight block through the screw hole by bolts or screws. Thus, by adding counterweights along the circumference of the wheel body 401, the rotational posture of the wheel body 401 is made more stable; especially when the eccentric shaft 403 drives the connecting rod structure 5 to reciprocate, the rotational posture is more stable.
[0032] Furthermore, the connecting rod structure 5 includes a connecting sleeve 501, a first connecting rod 502, a second connecting rod 503, and a connecting portion 504. The connecting sleeve 501 is connected to the eccentric rotating shaft 403. One end of the first connecting rod 502 and one end of the second connecting rod 503 are respectively connected to the connecting sleeve 501, and the other end of the first connecting rod 502 and the other end of the second connecting rod 503 are respectively provided with a connecting portion 504. Each connecting portion 504 is connected to a piston structure 6. Specifically, the connecting sleeve 501 is movably sleeved in the eccentric rotating shaft 403, so that when the eccentric rotating shaft 403 rotates in the wheel body 401, the connecting sleeve 501 can drive the first connecting rod 502 and the second connecting rod 503 to move left and right simultaneously. The connecting portion 504 can drive the two piston structures 6 to move left and right simultaneously following the first connecting rod 502 and the second connecting rod 503.
[0033] Furthermore, the piston structure 6 has a piston body 601, a connecting end 602, a sliding connecting arm 603, and a sliding part 604; the piston body 601 is movably sleeved in the piston cylinder body 7, and the connecting end 602 is provided on one side of the piston body 601, the connecting end 602 being connected to the connecting part 504; the two sliding connecting arms 603 are respectively disposed opposite to each other on both sides of the connecting end 602, and each sliding connecting arm 603 connects the piston body 601 and the sliding part 604 respectively.
[0034] Furthermore, the support frame 1 is provided with a plurality of sliding grooves 101, and each sliding part 604 is movably connected to one of the sliding grooves 101.
[0035] Specifically, the first connecting rod 502 or the second connecting rod 503 can drive the connecting end 602 through the connecting part 504, thereby driving the piston body 601 to reciprocate within the piston cylinder body 7. When the connecting rod structure 5 drives the piston structure 6, the sliding parts 604 corresponding to the ends of the two sliding connecting arms 603 located on both sides of the connecting end 602 can slide along the sliding groove 101, thereby guiding the sliding of the piston body 601 within the piston cylinder body 7, making its sliding process smoother and more stable.
[0036] In summary, the high-pressure dual-cylinder structure for atomizers of this utility model comprises a support frame 1, a drive motor 2, a drive shaft 3, an eccentric wheel structure 4, a connecting rod structure 5, a piston structure 6, and a piston cylinder body 7. The drive motor 2 is mounted on the support frame 1 and is drivenly connected to the drive shaft 3. The eccentric wheel structure 4 is movably disposed within the support frame 1, and the drive shaft 3 is drively connected to the eccentric wheel structure 4. The connecting rod structure 5 is connected to the eccentric wheel structure 4, and the two piston structures 6 are respectively connected to the two ends of the eccentric wheel structure 4. The two piston cylinder bodies 7 are disposed opposite to each other at the two ends of the support frame 1, and each piston structure 6 is movably fitted into one piston cylinder body 7. This invention relates to a high-pressure dual-cylinder structure for atomizers that can simultaneously drive two sets of piston devices to perform work, doubling the power utilization efficiency. As a result, it can output compressed air with higher pressure and greater flow rate per unit time. Therefore, this invention solves the technical problem of how to improve the air compression efficiency of piston-type compression mechanisms.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
