Description

Technical Field

[0001] The invention relates to an atomizing device, in particular to a heating type spray atomizing device. Background Art

[0002] Inhalation therapy is an important and effective treatment for respiratory diseases. For example, for diseases affecting the trachea, bronchi, alveoli, and thoracic cavity, such as colds, fevers, coughs, asthma, sore throats, pharyngitis, rhinitis, bronchitis, and pneumoconiosis, the principle of inhalation therapy is to atomize a medication solution into tiny particles. The drug is then rapidly transported into the respiratory tract and lungs through inhalation, where it is deposited and directly takes effect, achieving the goal of painless, rapid, and effective treatment. However, the nebulizers used in inhalation therapy generally lack a heating function, and the atomized medication inhaled by the patient during treatment is generally relatively cold. The inhaled cold medication can irritate the respiratory tract and lungs, easily causing respiratory spasms, causing significant discomfort and resistance in the patient, and hindering treatment. Furthermore, the inhaled cold medication solution can slow the cilia on the respiratory tract walls, thereby affecting the cilia's ability to move foreign matter attached to the respiratory tract walls toward the upper throat. Especially in winter when respiratory diseases are most prevalent, due to the low temperature in winter, the temperature of the inhaled low-temperature atomized liquid medicine will be closer to zero degrees, which will cause the cilia on the walls of the respiratory tract to stop swinging completely, making it impossible to move foreign matter attached to the walls of the respiratory tract toward the upper throat, and unable to effectively prevent foreign matter from reaching the alveoli. In order to solve the atomization problem of low-temperature liquid medicine, it is necessary to add a heating module to the physical and chemical device. However, the existing heating module is generally arranged at the bottom of the liquid medicine chamber of the nebulizer or wrapped around the periphery of the liquid medicine chamber, but the heating efficiency of this method is relatively low, and since the capacity of the liquid medicine chamber is generally only tens of milliliters, as the liquid medicine is continuously atomized, it is easy to make the temperature of the un-atomized liquid medicine too high, which not only causes the efficacy of the liquid medicine to fail, but also causes the atomized liquid medicine with too high a temperature to damage the respiratory tract and lungs.

[0039] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments.

[0040] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Various embodiments of the present invention will now be described with reference to the accompanying drawings. In the subsequent description, suffixes such as "module," "component," or "unit" used to denote components are used solely to facilitate description of the present invention and do not inherently have specific meanings. Therefore, "module" and "component" may be used interchangeably.

[0042] like Figure 9 , Figure 10 and Figure 11 As shown, a heating type spray atomization device is characterized in that it includes a spray atomization module and a heating module, and the heating module can be installed in the spray atomization module in a pluggable manner.

[0043] By adopting this setting mode in which the heating module can be installed in the jet atomization module in a pluggable manner, the heating module containing electronic components and the jet atomization module not containing electronic components can be designed and manufactured separately, so that the heating module and the jet atomization module as a consumable can be designed, manufactured and used separately, thereby greatly reducing the overall use cost of the device, alleviating the burden on patient users, and also complying with the environmental protection concept of saving resources.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 12As shown, the spray atomization module includes: an atomized liquid medicine outlet 11, a connecting pipe 12, an atomizing cavity 14, a liquid medicine chamber 15, a compressed air inlet pipe 16, a liquid medicine atomizing nozzle 17, a first placement chamber 18-1, and a second placement chamber 18-2. The atomized liquid medicine outlet 11 is connected to the connecting pipe 12, which is connected to the atomizing cavity 14, and the atomizing cavity 14 is connected to the liquid medicine chamber 15, thereby forming a complete cavity for atomizing the liquid medicine. The first placement chamber 18-1 and the second placement chamber 18-2 are respectively arranged in the lower half of the liquid medicine chamber 15 from top to bottom. The first placement chamber 18-1 and the second placement chamber 18-2 are parallel to each other. The central axis of the compressed air input pipe 16 coincides with the central axis of the liquid medicine chamber 15, and the central axis of the liquid medicine atomizing nozzle 17 also coincides with the central axis of the liquid medicine chamber 15. The compressed air input pipe 16 is arranged inside the liquid medicine atomizing nozzle 17. There is a space between the outer wall of the compressed air input pipe 16 and the inner wall of the liquid medicine atomizing nozzle 17. The compressed air input pipe 16 is provided with a compressed air atomizing nozzle 19 at the top end within the liquid medicine chamber 15. The liquid medicine atomizing nozzle 17 is provided with a liquid medicine atomizing nozzle 17-1 at the top end within the liquid medicine chamber 15. The aperture of the liquid medicine atomizing nozzle 17-1 is larger than the aperture of the compressed air atomizing nozzle 19. Therefore, the input compressed air is ejected at high speed toward the atomization cavity 14 through the compressed air atomization nozzle 19 via the compressed air input pipe 16. The high-speed ejected airflow drives the liquid medicine in the liquid medicine cavity 15 to flow into the liquid medicine through hole 17-2, and flows toward the liquid medicine atomization nozzle 17-1 through the gap between the outer wall of the compressed air input pipe 16 and the inner wall of the liquid medicine atomization nozzle 17, and finally is sprayed toward the atomization cavity 14 in an atomized manner through the liquid medicine atomization nozzle 17-1, and finally is delivered to the patient for treatment through the atomized liquid medicine outlet 11.

[0045] In addition, liquid medicine can be injected or replenished into the liquid medicine chamber 15 through the injection port 13. As a consumable, the spray atomization module has the advantages of reliable structure, convenient disassembly and assembly, reliable and stable atomization effect, easy mass production and low cost.

[0046] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the heating module includes: a heating module housing 21, a heating control unit 22, a first fan-shaped heating plate 23-1, and a second fan-shaped heating plate 23-2. The heating control unit 22 is disposed on the outer wall of the heating module housing 21, and the first fan-shaped heating plate 23-1 and the second fan-shaped heating plate 23-2 are disposed on the inner wall of the heating module housing. The heating module housing 21 matches the shape of the outer wall of the liquid medicine chamber 15, the first fan-shaped heating plate 23-1 matches the shape of the first placement cavity 18-1, and the second fan-shaped heating plate 23-2 matches the shape of the second placement cavity 18-2.

[0047] By inserting the heating module into the spray atomization module, the liquid medicine in the liquid medicine chamber 15 is heated by the first sector-shaped heating plate 23-1 and the second sector-shaped heating plate 23-2. This achieves higher heating efficiency than a conventional heating method that wraps around the outer wall of the liquid medicine chamber 15. Furthermore, the heating method is simpler in structure than a heating method in which the heating device is disposed inside the spray atomization module, thereby facilitating easy processing and reducing costs.

[0048] When the liquid level of the medicine in the medicine liquid chamber 15 is higher than the first placement chamber 18-1, due to the heating mode of the upper and lower layers of heating plates, the medicine in the medicine liquid chamber 15 can be heated simultaneously by the first fan-shaped heating plate 23-1 and the second fan-shaped heating plate 23-1, thereby having the characteristic of high heating efficiency.

[0049] As the liquid medicine in the liquid medicine chamber 15 is continuously atomized and discharged from the atomized liquid medicine outlet 11, the liquid level in the liquid medicine chamber 15 also continuously decreases. When the liquid medicine level is lower than the first placement cavity 18-1, the first sector-shaped heating plate 23-1 no longer heats the liquid medicine in the liquid medicine chamber 15. Thus, the function of automatically regulating the heating of the liquid medicine in the liquid medicine chamber 15 can be achieved at a physical level. This also avoids the drawbacks of conventional heating methods, such as excessively high liquid medicine temperature caused by a decrease in the liquid medicine chamber 15 and an inability to adjust the heating power in a timely manner, which affects the efficacy of the liquid medicine and also causes damage to the patient's respiratory tract from the overly hot atomized liquid medicine.

[0050] Further, if Figure 5 and Figure 8 As shown, the sector angle of the first sector heating plate 23-1 ranges from [180 。 , 270 。 ], the value range of the sector angle of the second sector heating plate 23-2 is [180 。 , 270 。], the value range of the first placement cavity 18-1 corresponding to the first fan-shaped heating plate 23-1 is [180 。 , 270 。 ], the value range of the sector angle of the second placement cavity 18-2 corresponding to the second sector heating plate 23-2 is [180 。 , 270 。 The first fan-shaped heating plate 23-1 and the second fan-shaped heating plate 23-2 are made of a flexible, soft-rubber material, and the heating module housing 21 is made of a flexible, soft-rubber material. Setting the fan-shaped angle of the first fan-shaped heating plate 23-1 and the second fan-shaped heating plate 23-2 to exceed 180 degrees increases the contact area between the heating plate and the liquid medicine, providing a better overall heating effect and further improving heating efficiency.

[0051] Further, if Figure 1 , Figure 2 , Figure 5 and Figure 12 As shown, the angle between the plane of the first placement cavity 18-1 and the central axis of the liquid medicine cavity 15 is in the range of [45 。 , 90 。 ], the angle between the plane of the first sector-shaped heating plate 23-1 corresponding to the first placement cavity 18-1 and the central axis of the liquid medicine cavity 15 is in the range of [45 。 , 90 。 ], the angle between the plane of the second placement cavity 18-2 and the central axis of the liquid medicine cavity 15 is in the range of [45 。 , 90 。 ], the angle between the plane of the second sector-shaped heating plate 23-2 corresponding to the second placement cavity 18-2 and the central axis of the liquid medicine cavity 15 is in the range of [45 。 , 90 。 ].

[0052] That is, setting the first fan-shaped heating plate 23-1 and the second fan-shaped heating plate 23-2 at an inclined angle can appropriately increase the contact area between the heating plate and the liquid medicine, provide a better overall heating effect, and further improve the heating efficiency. In addition, due to the inclined setting of the heating plate, the liquid medicine within the liquid medicine chamber 15 at a certain depth can be in contact with the heating plate and can be directly heated. Therefore, as the liquid medicine in the liquid medicine chamber 15 is continuously atomized and discharged from the atomized liquid medicine outlet 11, the liquid level of the liquid medicine in the liquid medicine chamber 15 also continuously decreases, and the contact area between the liquid medicine in the liquid medicine chamber 15 and the heating plate is reduced at the physical level, thereby realizing the function of precise automatic heating control, avoiding the excessive temperature of the liquid medicine caused by the reduction of the liquid medicine in the liquid medicine chamber 15 and the inability to adjust the heating power in time, which affects the efficacy of the liquid medicine, and also causes the patient's respiratory tract to be damaged by the overly high temperature atomized liquid medicine.

[0053] Furthermore, the angle between the plane of the first placement cavity 18-1 and the central axis of the liquid medicine cavity 15 is 45°. 。 The angle between the plane of the first sector-shaped heating plate 23-1 corresponding to the first placement cavity 18-1 and the central axis of the liquid medicine cavity 15 is 45 。 The angle between the plane of the second placement cavity 18-2 and the central axis of the liquid medicine cavity 15 is 45 。 The angle between the plane of the second sector-shaped heating plate 23-2 corresponding to the second placement cavity 18-2 and the central axis of the liquid medicine cavity 15 is 45 。 .

[0054] The angle is 45 。 The contact area between the heating plate and the liquid medicine can be increased, providing a better overall heating effect and further improving the heating efficiency. In addition, since the inclination angle of the heating plate is 45 。 The liquid medicine within the liquid medicine chamber 15 at a certain depth can be in contact with the heating plate and can be directly heated. Therefore, as the liquid medicine in the liquid medicine chamber 15 is continuously atomized and discharged from the atomized liquid medicine outlet 11, the liquid level of the liquid medicine in the liquid medicine chamber 15 also continuously decreases, and the contact area between the liquid medicine in the liquid medicine chamber 15 and the heating plate is reduced at the physical level, thereby achieving the function of precise automatic heating control, avoiding the defect of the traditional heating mode that causes the liquid medicine temperature to be too high due to the reduction of the liquid medicine in the liquid medicine chamber 15 and the inability to adjust the heating power in time, thereby affecting the efficacy of the liquid medicine, and also causing the patient's respiratory tract to be damaged by the overly high temperature atomized liquid medicine.

[0055] Furthermore, the sector angle of the first sector heating plate 23-1 is 270°.。 The sector angle of the second sector heating plate 23-2 is 270 。 The sector angle of the first placement cavity 18-1 corresponding to the first sector heating plate 23-1 is 270 。 The sector angle of the second placement cavity 18-2 corresponding to the second sector heating plate 23-2 is 270 。 .

[0056] The fan angle is 270 。 The contact area between the heating plate and the liquid medicine can be increased, providing a better overall heating effect and improving heating efficiency.
