Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a rock salt aerosol therapy device. Background Technology
[0002] Nebulized inhalation therapy is one of the commonly used methods for treating respiratory diseases. It uses a nebulizer to atomize liquid medication into tiny particles, which are then inhaled by the patient into the respiratory tract and lungs to achieve the therapeutic goal. Clinically commonly used compressor nebulizers generally include a nebulizer pump unit, an air delivery tube, a nebulizer cup, a mouthpiece, and a mask. The nebulizer cup is connected to the nebulizer pump unit via an air delivery tube, and the mouthpiece or mask is connected to the air outlet tube of the nebulizer cup.
[0003] The atomizing pump unit, also known as the dust aerosol generator unit, currently primarily uses a piston-type air pump. It draws in filtered air, pressurizes it, and outputs it. This type of structure suffers from excessive noise from the air pump components and the airflow within the main unit's piping. Excessive noise can easily irritate the auditory nerves of patients and medical staff, causing physiological discomfort and potentially affecting their mood. Furthermore, the existing structure makes filter replacement inconvenient, requiring effort and sometimes tools, which adds to the inconvenience of daily use. Finally, the existing main unit design is difficult to assemble during production, resulting in long assembly times and high costs.
[0004] In addition, existing nebulizer cups have problems such as low aerosol generation efficiency, powder residue, and large size that makes disassembly and assembly inconvenient. When used in combination with the nebulizer pump host, they affect the treatment effect to some extent.
[0005] Based on this, this utility model has developed an improved rock salt aerosol therapy device, which optimizes the structure of its nebulizer pump host and nebulizer cup.

[0019] Furthermore, the first, second, and third damping pads disposed within the upper fixing groove assembly constitute the upper damping component.
[0020] Furthermore, the opening direction of the slots on the first, second, and third plates changes to guide the muffler pipe into a gentle hook-shaped bend.
[0021] Furthermore, the first and second support columns are hollow inside, and an arc-shaped top surface is provided on the top of the first and second support columns along their arrangement direction. The first and second shock-absorbing pads are detachably inserted into the first and second support columns respectively.

[0022] Furthermore, insertion parts are provided inside the first and second support slots, and protrusions that mate with the insertion parts are provided on the bottom surfaces of the first and second shock-absorbing pads. The insertion parts ensure that the shock-absorbing pads assembled within the first and second support slots can be more securely nested. That is, the shape of the insertion parts within the first and second support slots can be flexibly configured into different structural styles.
[0023] Furthermore, the structures of the first and second support groove columns mentioned above are slightly different, which in turn makes the structures of the first and second shock-absorbing pads assembled with them slightly different.

[0031] Furthermore, the porous air damper is truncated conical in shape. Its outer diameter gradually decreases from the muffler inlet to the muffler outlet. The porous air damper is made of porous material.
[0032] Furthermore, the noise reduction principle of the above-mentioned mufflers is to change the airflow propagation path and speed through methods such as blocking, bending, and expansion, so that the energy of the high-speed airflow is converted into heat energy and sound energy, thereby achieving a noise reduction effect. Its main principle is to utilize the porous material and non-uniform cross-sectional shape inside the muffler, causing the airflow to undergo multiple reflections, refractions, and scatterings as it passes through the muffler, thus achieving the purpose of noise reduction. Specifically, high-flow-rate air enters from the inlet of the muffler and reaches the porous air damper. Utilizing the internal porous material and non-uniform cross-sectional shape, the airflow undergoes multiple reflections, refractions, and scatterings as it passes through the muffler, thereby achieving the purpose of noise reduction.

[0049] The beneficial effects of this utility model are:
[0050] 1. This utility model relates to a rock salt aerosol therapy device. The nebulizer pump (gas generator) features a shock-absorbing and noise-reducing design. A shock-absorbing component is installed within the pump assembly's mounting groove to accommodate deformation during shock absorption, ensuring balanced shock absorption in every direction of pump assembly vibration. This effectively mitigates vibrations caused by the pump's operation, thereby reducing operating noise. A silencer is connected in series on the air intake pipe (silencer pipe), reducing noise from uncompressed high-flow-rate airflow. The air intake pipe's arrangement within the housing uses a gentle (higher-order flow) curve shape, reducing additional airflow noise caused by abrupt changes in airflow direction. The air intake pipe and silencer are fixed using a slotted design, ensuring high reliability and allowing for easy hand assembly. The shock-absorbing pads in the shock-absorbing component have varying shapes, minimizing assembly errors. The filter cotton at the air intake is also easy to install and remove by hand, facilitating filter cotton replacement.
[0051] 2. The nebulizer cup of this aerosol therapy device adopts a newly designed pneumatic cavity, enabling the production of a small-volume product that can be held with one hand. This new pneumatic cavity can achieve a more uniform airflow, which is conducive to aerosol generation and can eliminate drug powder residue, thus achieving full utilization of the drug powder; the tight sealing design prevents airflow leakage inside the pneumatic cavity, further realizing the full utilization of drug powder while ensuring the performance of aerosol generation.

Detailed Implementation
[0073] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0074] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0075] like Figure 1The diagram shows the overall structure of the rock salt aerosol therapy device, which mainly includes a gas generating pump 1 and an atomizing cup 2 that are assembled and connected. As can be seen from the diagram, the atomizing cup is smaller in size, making it more convenient to use, disassemble, and clean, and providing a better handheld experience during atomization therapy.
[0076] See Figures 2-15 The diagram illustrates the structure of the gas generating pump 1, which includes a sealed upper housing 3, a lower housing 4, and an air pump assembly 5 disposed within the housings. An air inlet is provided on the side wall of the lower housing, and an air outlet is provided on the side wall of the upper housing corresponding to the air inlet. The gas generating pump 1 compresses the air filtered through the air inlet using the air pump assembly 3 and pumps it into the atomizing cup 2.
[0077] A silencer 6, a pump assembly fixing groove 7, a shock absorption assembly 8, and a silencer pipe guide structure 9 are provided inside the lower housing 4. The silencer guide structure is used to guide the silencer pipe 10 (i.e., the air inlet pipe) connected to the inlet of the silencer 6. The silencer pipe guide structure 9 includes three air pipe guide grooves distributed from the air inlet towards the silencer 6. The air pipe guide grooves guide the silencer pipe so that it smoothly bends and extends within the housing with the air inlet as the starting end. The silencer pipe is connected to the silencer inlet end, and the pump inlet pipe 11, which is connected to the silencer outlet end, is connected to the air pump assembly 5. The air pump assembly is connected to the outlet of the gas generating pump via the pump outlet pipe 12.
[0078] The silencer 6 is located inside the lower housing 4 on the side near the air outlet of the upper housing 3.
[0079] The pump assembly fixing groove 7 is located in the middle of the housing. The shock absorption component 8 is fitted into the pump assembly fixing groove 7, supporting the air pump assembly 5 and providing buffering and shock absorption during its operation. Specifically, the pump assembly fixing groove 7 includes an upper fixing groove assembly in the upper housing 3 and a lower fixing groove assembly in the lower housing 4. The shock absorption component 8 includes an upper shock absorption component in the upper fixing groove assembly and a lower shock absorption component in the lower fixing groove assembly. The silencer 6, air pipe guide groove, lower fixing groove assembly, and lower shock absorption component are arranged in the lower housing 4. The upper fixing groove assembly and upper shock absorption component are arranged on the top wall of the upper housing 3. The upper and lower fixing groove assemblies are arranged vertically and vertically, and the upper and lower shock absorption components are arranged vertically and vertically. The bottom sides of the air pump assembly 5 are supported by the lower shock absorption component in the lower fixing groove assembly, and the top sides of the air pump assembly abut against the upper shock absorption component in the upper fixing groove assembly after the upper and lower housings are assembled.
[0080] The aforementioned lower fixing groove assembly includes a first support groove column 13 and a second support groove column 14 spaced apart. A first retaining plate 15 is provided between the first and second support groove columns, and a first retaining groove 150 is provided on the first retaining plate. A first support column 16 is provided on the outer side of the first and second support groove columns away from the air inlet. A second retaining plate 17 is provided between the first support column 16 and the second support groove column 14, and a second retaining groove 170 is provided on the second retaining plate. A muffler fixing plate 18 is provided on the inner side wall of the lower housing near the air outlet of the gas generating pump. A third retaining plate 19 is provided on the outer side of the muffler fixing plate near the second support groove column, and a third retaining groove 190 is provided on the third retaining plate. The muffler pipe bends and extends from the air inlet to the muffler inlet end and passes sequentially through the retaining grooves on the first retaining plate 15, the second retaining plate 17, and the third retaining plate 17. The opening direction of the retaining grooves on the first, second, and third retaining plates changes to guide the muffler pipe to bend gently in a hook shape. See [reference needed]. Figure 6 The routing of the silencer duct.
[0081] The aforementioned lower damping assembly includes a first damping pad 20, a second damping pad 21, and a third damping pad 22 that are respectively inserted into and cooperate with the first and second support groove columns and the first support column.
[0082] The aforementioned upper fixing groove assembly includes a third support groove post 23 and a fourth support groove post 24 corresponding to the first and second support groove posts. First and second damping pads are assembled inside the third and fourth support groove posts. A second support post 25 is provided on the outside of one end of the third and fourth support groove posts, corresponding to the first support post. A third damping pad is provided inside the second support post 25. The first, second, and third damping pads provided in the upper fixing groove assembly constitute the aforementioned upper damping assembly. Therefore, it can be seen that the first and second support groove posts correspond to the third and fourth support groove posts respectively, and their structures are identical; the structures of the first and second support posts are also identical.
[0083] The first and second support columns are hollow inside, with an arc-shaped top surface extending along their arrangement direction at the top of each column. The first and second damping pads are detachably inserted into the first and second support columns, respectively. The tops of both the first and second damping pads are semi-circular arc-shaped grooves with one open end. Specifically, an insertion part 26 is provided inside the first and second support columns, and a protrusion 27 is provided on the bottom surface of the first and second damping pads to engage with the insertion part. The insertion part ensures that the damping pads assembled in the first and second support columns can be more securely nested. That is, the shape of the insertion part can be flexibly configured into different structural styles within the first and second support columns. For example, it can be adopted as follows: Figure 5The structure shown comprises two partition plates located within the first and second support slots. The tops of the partition plates have the same curvature as the tops of the first and second support slots. A recessed opening is provided in the middle of the partition plate, and a protrusion that mates with the recessed opening is provided at the bottom of the first and second damping pads. This design ensures that the flexible first and second damping pads, after being inserted into the first and second support slots, are securely attached to the partition plates and are not easily moved or fall out.
[0084] Furthermore, the structures of the first and second support columns mentioned above are slightly different, which in turn leads to slight differences in the structures of the first and second damping pads that are assembled with them. This difference aims to achieve better fit and secure the air pump assembly. Simultaneously, the difference in the damping pads also reduces the likelihood of assembly errors. These differences can be modified to suit the corresponding structural positions of the air pump assembly 5 that require support and fixation in practice. Specifically, based on... Figure 6 For example, in the structure of the first damping pad 20 shown, there is an insertion plate 200 that is fitted into the partition plate inside the first support groove column. The arc-shaped bottom surface and the protrusion 27 on the arc-shaped bottom surface between the two insertion plates realize the assembly with the first support groove column 13. A protruding semi-circular support edge 130 is provided on the outside of the first support groove column 13. Corresponding to the semi-circular support edge, a semi-circular outer protrusion 201 is provided on the outside of the closed end of the semi-circular arc groove surface of the first damping pad 20. The semi-circular outer protrusion matches the semi-circular support edge. Figure 7 The bottom surface of the first damping pad 20 is shown, and it can be seen that a hollow area 202 is provided in the middle of its arc-shaped bottom surface, which can further increase the damping effect. The semi-circular arc-shaped groove surface of the first damping pad serves as a support surface to support the outer end of the support column 500 at the bottom of the air pump assembly 5.
[0085] The structural difference between the second support groove column 14 and the first support groove column 13 is that, Figure 5 The second support column 14 has chamfered corners at its four internal corners, and no semi-circular support edge is provided on its outer side. See also Figure 8 and Figure 9 The structure of the second shock-absorbing pad 21 is shown. It is provided with a plug plate 210 that is inserted into the partition plate inside the second support column 14. Four chamfers 211 are provided at the outer corners of the plug plate. The arc-shaped bottom surface and the protrusion 27 provided on the arc-shaped bottom surface between the two plug plates realize the assembly with the second support column 14. Figure 9The structural design of the second damping pad is consistent with the bottom structure of the first damping pad 20. The semi-circular groove of the second damping pad serves as a support surface, cooperating with the first damping pad to support and fix the other outer end of the support column 500 at the bottom of the air pump assembly. It should be noted that, based on the actual shape of the outer end of the support column 500 at the bottom of the air pump assembly 5, the positions of the semi-circular grooves of the first and second damping pads can be adjusted accordingly to ensure a better fit and stable support for the air pump assembly support column. For example, the aforementioned "can be adjusted accordingly" refers to... Figure 6 , Figure 8 The top semi-circular grooves of the first and second shock-absorbing pads are shown. It can be seen that the opposite sidewalls of each semi-circular groove near the closed end are also provided with a wedge-like structure. This design is flexibly set based on the shape of the bottom support column 500 of the air pump assembly 5 in actual use, all for the purpose of achieving better stable support and convenient assembly.
[0086] Both the first and second shock-absorbing pads mentioned above are made of silicone. The dimensions of their top semi-circular grooves are reasonably set according to the outer diameter of the support column of the air pump assembly to be supported and fixed.
[0087] The first support column 16 and the second support column 25 are both hollow support columns; the third damping pad 22 includes a columnar body 220 and a circular end cap 221 at one end of the columnar body, the columnar body being hollow; the third damping pad is also made of silicone. The outer diameter of the circular end cap is larger than the other end face of the columnar body; the hollow area of the columnar body consists of holes evenly distributed thereon, the holes gradually decreasing in size from the outside to the inside, and the horizontal cross-section of the holes is an isosceles trapezoidal shape. After the upper and lower shells are assembled, the third damping pad 22, located in the first and second support columns, abuts against the bottom and top surfaces of the air pump assembly 5 through the position of its circular end cap.
[0088] The aforementioned muffler 6 includes a bottom cover 600, an upper cover 601, and a porous air damper 604 and an air passage 605 disposed inside. The bottom cover and upper cover, after being threaded together, form a cylindrical cavity 606. The porous air damper 604 and the air passage 605 are disposed within the cylindrical cavity. One end of the porous air damper is connected to the air passage 605, which is formed by a tube. The end of the tube connected to the porous air damper 604 is connected via a plug-in connection, and the other end of the tube is sealed to the muffler's air inlet. A plate 607 is disposed at the connection point between the bottom cover 600 and the muffler's air outlet 603. The plate surrounds the outer periphery of the muffler's air outlet within the bottom cover, and the other end of the porous air damper is abutted and fixed to the outer end of the plate. See details. Figures 13-15 The muffler structure is shown. The aforementioned porous air damper is arranged in a frustum shape, with the outer diameter gradually decreasing from the muffler inlet 602 to the muffler outlet 603; the porous air damper is made of porous material.
[0089] The noise reduction principle of the above-mentioned mufflers is to change the propagation path and speed of airflow through methods such as blocking, bending, and expansion, so that the energy of high-speed airflow is converted into heat energy and sound energy, thereby achieving a noise reduction effect. Its main principle is to utilize the porous material and non-uniform cross-sectional shape inside the muffler, causing the airflow to undergo multiple reflections, refractions, and scatterings as it passes through the muffler, thus achieving the purpose of noise reduction. Specifically, high-flow air enters from the muffler inlet 602, passes through the air passage 605 to the porous air damper 604, and utilizes the internal porous material and non-uniform cross-sectional shape to cause multiple reflections, refractions, and scatterings of the airflow as it passes through the muffler, thereby achieving the purpose of noise reduction.

[0098] Working principle and process:
[0099] The gas generating pump 1 and the nebulizer cup 2 are connected by a pipeline. When the gas generating pump 1 is powered on, the air pump assembly 5 of the gas generating pump operates, drawing air in through its air inlet. The high-speed airflow passes through the silencer pipe 10 and enters the silencer 6 to reduce noise. It continues to enter the air pump through the pipeline guided by the silencer pipe guide structure 9, where it is compressed and pumped out as high-pressure gas. During this process, the shock-absorbing component 8 in the pump assembly fixing groove 7 has an excellent shock-absorbing effect during pumping, reducing the operating noise caused by vibration and alleviating the patient's anxiety. The high-pressure gas output from the gas generating pump 1 is input into the gas input chamber of the nebulizer cup 2 through the pipeline via the air inlet connector 40. The high-pressure gas is evenly distributed in the gas input chamber to multiple gas injection holes 41 on the side wall of the lower inner liner, and then injected into the lower cavity 37. During this process, the airflows interact with each other, forming a swirling flow around the inner wall of the lower cavity. The swirling flow contacts the drug powder in the lower cavity and exerts shear force, carrying away the drug powder and spreading it during the rotation, generating an aerosol. After entering the upper inner liner 32, the aerosol vortex passes sequentially through the third chamber 3203, the second chamber 3202, and the first chamber 3201. Due to the narrowing of the second chamber, the rising vortex experiences a decrease in local pressure at this narrow point due to the reduced cross-sectional area of the channel and increased gas velocity. This creates a suction effect on the airflow in the lower chamber (Venturi effect), which facilitates the upward movement of the aerosol vortex. The upward speed of the vortex is much lower than its rotational speed; this ensures that the vortex has sufficient time to carry enough powder and generate a sufficiently concentrated aerosol. The continuing upward-rising aerosol enters the separator and is discharged sequentially through separator vents 336 at different locations on the three separators. During this process, the airflow needs to undergo multiple sharp 90-degree turns, causing most of the larger aerosol particles to settle due to their greater mass, while the more uniformly dispersed and finer aerosol particles eventually enter the top cover. This has a positive impact on the medical treatment effect and ensures high efficiency in aerosol separation. Meanwhile, the particulate aerosols in the aforementioned stagnant airflow will repeatedly pass upward through the separator, thereby gradually reducing the particle size, eliminating drug powder residue, and ensuring full utilization of the drug powder.
