This application claims the benefit of priority to Taiwan Patent Application No. 110110579, filed on Mar. 24, 2021. The entire content of the above identified application is incorporated herein by reference.

Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein.

FIELD OF THE DISCLOSURE

The present disclosure relates to a nebulizer device and a nozzle module, and more particularly to a nebulizer device and a nozzle module that can reduce aggregation, collision, and condensation of atomized particles and improve aerosol guiding efficiency.

BACKGROUND OF THE DISCLOSURE

A nebulizer device is widely used in various industries, such as for purposes of cooling, humidification, disinfection, dust suppression, and medical applications. For example, when the nebulizer device is used as a medical inhaler device, a particle size of a nebulized liquid drug must be smaller than 3 μm to 5 μm to ensure that the drug can effectively reach the lower respiratory tract and be directly absorbed by a human body, so as to improve an effectiveness of the treatment with the drug.

In order to improving an atomized particle delivery efficiency of a conventional nebulizer device, holes are created on the nebulizer device to introduce external air into the nebulizer device. However, air guiding structures are not provided inside of the nebulizer device, and the holes on the nebulizer device are not designed to guide aerosol flow. Therefore, a turbulent flow is generated when the external air enters into the nebulizer device through the holes, which causes atomized particles to easily aggregate and collide with one another and condense into large liquid droplets, so that a delivery of a final output of the nebulized liquid drug to the human body is reduced.

Therefore, how to overcome the abovementioned shortcomings through an improvement of a structural design of the nebulizer device and the nozzle module has become one of the important issues to be solved in this industry.

SUMMARY OF THE DISCLOSURE

The main body unit corresponds to an inner wall of the accommodating space and protrudes toward the accommodating space to form a plurality of guiding parts, and each of the guiding parts is adjacent to one of the openings. The guide unit is disposed in the accommodating space and has a recessed part. The control module can be detachably connected to the main body unit.

In another aspect, the present disclosure provides a nozzle module, which includes a main body unit and a guide unit. The main body unit has a plurality of openings penetratingly formed through the main body unit, an accommodating space, and an output part, and the openings and the output part are in spatial communication with the accommodating space. The main body unit corresponds to an inner wall of the accommodating space and protrudes toward the accommodating space to form a plurality of guiding parts, and each of the guiding parts is adjacent to one of the openings.

First Embodiment

Reference is made to FIG. 1 to FIG. 6, which are respectively an exploded view of a nebulizer device, an exploded view of a nozzle module, a structural view of the nozzle module, a first schematic view of a flow trajectory of a gas and a pressure distribution, a second schematic view of the flow trajectory of the gas and the pressure distribution, and a schematic view of an injection trajectory of atomized particles of the nebulizer device according to a first embodiment of the present disclosure. As shown in the figures, the present disclosure provides a nebulizer device Z, which includes a nebulizer module 1, a nozzle module N, and a control module 2. The nebulizer module 1 can be an atomization component for accommodating and atomizing liquid, and the control module 2 can be a host for the nebulizer device, but are not limited thereto.

As shown in FIG. 1 and FIG. 2, the nozzle module N can include a main body unit N1 and a guide unit N2. For example, the main body unit N1 can be a casing structure; in this embodiment, the main body unit N1 is an example of a multi-piece structure. For example, the main body unit N1 includes a first main body N1a and a second main body N1b, the first main body N1a can be detachably connected to the second main body N1b, but is not limited thereto, and the main body unit N1 can also be a single component structure. The main body unit N1 can be detachably connected to the nebulizer module 1. Furthermore, as shown in FIG. 1 and FIG. 2, one end of the main body unit N1 can be detachably connected to the nebulizer module 1, and another end of the main body unit N1 can be detachably connected to the control module 2. The main body unit N1 can have a plurality of openings N10a, N10b, and N10c penetratingly formed through the main body unit N1, an accommodating space N11, and an output part N12, and the openings N10a, N10b, and N10c and the output part N12 are in spatial communication with the accommodating space N11. The openings N10a and N10b are located on both sides of the main body unit N1 and the opening N10c, the opening N10c is located on a rear side of the main body unit N1, and the output part N12 is located at a front side of the main body unit N1. More preferably, the opening N10a is disposed opposite to the opening N10b, and the opening N10c is disposed opposite to the output part N12, but it is not limited thereto.

As shown in FIG. 1 and FIG. 2, the guide unit N2 is disposed in the accommodating space N11 and has a recessed part N20. For example, the guide unit N2 can be a long plate-shaped structure and can be divided into a first area N2a and a second area N2b. The first area N2a can correspond to the output part N12, and the second area N2b can correspond to the accommodating space N11, but it is not limited thereto. The second area N2b of the guide unit N2 can be recessed to form the recessed part N20.

Therefore, as shown in FIG. 1 to FIG. 6, FIG. 4 and FIG. 5 show that flow trajectories of gas and gas flow in the nozzle module N have a plurality of different pressure distributions P1, P2, P3, P4, P5, P6, P7, P8, and P9. When the nebulizer module 1 provides atomized particles (such as atomized distilled water, physiological saline, artificial tears, medicinal solution, drug suspension, biologics, etc.) into the accommodating space N11, a first gas introduced through a portion of the openings N10a and N10b forms a first gas flow on the guide unit N2 and the recessed part N20 (the pressure distributions P1 and P2 in FIG. 4 and FIG. 5), that is, a high-pressure flow field vortex is formed. A second gas (the pressure distribution P2 in FIG. 4 and FIG. 5) introduced through another one of the openings N10c enters the accommodating space N11, and an interaction between the first gas flow and the second gas generates a second gas flow having a directional high and low pressure difference and a relatively low pressure being lower than a pressure of the first gas flow (the pressure distributions P3, P4, P5, P6, P7, P8, and P9 in FIG. 4 and FIG. 5). At the same time, the flow trajectory of the second gas flow guides the atomized particles to move in a direction of the output part N12 to deliver the atomized particles to an outside of the nozzle module N via the output part N12. Moreover, in conjunction with the injection trajectory V of the atomized particles shown in FIG. 6, the atomized particles are guided by the first gas flow and the second gas flow to move smoothly in a direction of a nozzle without flowing downwards.

In addition, the simulations of the pressure distributions are as shown in FIG. 4 and FIG. 5. The pressure distribution P1 can be between 101316.76 Pa to 101319.80 Pa, the pressure distribution P2 can be between 101313.72 Pa to 101316.76 Pa, the pressure distribution P3 can be between 101310.67 Pa to 101313.72 Pa, the pressure distribution P4 can be between 101307.63 Pa to 101310.67 Pa, the pressure distribution P5 can be between 101304.59 Pa to 101307.63 Pa, the pressure distribution P6 can be between 101301.55 Pa to 101304.59 Pa, the pressure distribution P7 can be between 101298.51 Pa to 101301.55 Pa, the pressure distribution P8 can be between 101295.47 Pa to 101298.51 Pa, and the pressure distribution P9 can be between 101292.43 Pa to 101295.47 Pa, but are not limited thereto.

Accordingly, the nebulizer device Z of the present disclosure adopts the abovementioned technical solution to form the high-pressure flow field vortex (that is, the first gas flow) on the guide unit N2 and the recessed part N20 via the first gas introduced through the portion of the openings N10a and N10b, the second gas introduced through the another one of the openings N10c interacts with the first gas flow to generate the second gas flow having the directional high and low pressure difference and the relatively low pressure being lower than the pressure of the first gas flow, and the nebulizer device Z drives the nebulizer module 1 to provide the atomized particles in the accommodating space N11 to move smoothly in the direction of the nozzle, so as to reduce the aggregation, collision, and condensation of the atomizing particles and improve the aerosol guiding efficiency.

In addition, according to what was mentioned above, the present disclosure further includes a nozzle module N, which includes a main body unit N1 and a guide unit N2. The main body unit N1 has a plurality of openings N10a, N10b, and N10c penetratingly formed through the main body unit N1, an accommodating space N11, and an output part N12, and the openings N10a, N10b, and N10c and the output part N12 are in spatial communication with the accommodating space N11.

As shown in the figures, the same components of the nebulizer device Z of this embodiment and the nebulizer device Z of the abovementioned first embodiment operate in a similar manner, and will not be repeated herein. It is worth noting that in this embodiment, the guide unit N2 further has a protruding part N21, and the protruding part N21 is adjacent to the recessed part N20.

The first gas forms the first gas flow between the protruding part N21, the recessed part N20, and the guiding parts N13.

For example, as shown in FIG. 7, FIG. 8, and FIG. 10, the protruding part N21 of the guide unit N2 can be located under the opening N10c. The inner wall of the main body unit N1 protrudes toward the accommodating space N11 to form the guiding parts N13. In this embodiment, the guiding parts N13 correspond to the openings N10a and N10b and are respectively located under the openings N10a and N10b, but it is not limited thereto. Furthermore, the guiding parts N13 can be oppositely disposed and located on both sides of the recessed part N20 or both sides of the protruding part N21, and the guiding parts N13 can be detachably connected to the guide unit N2. The recessed part N20 faces the nebulizer module 1, and the protruding part N21 is located between the recessed part N20 and the one of the openings N10c.

Therefore, as shown in FIG. 7, FIG. 8, and FIG. 10, when the first gas is introduced into the accommodating space N11 through the openings N10a and N10b, the first gas can form a vortex between the guiding parts N13, the protruding part N21, and the recessed part N20, so as to form a high-pressure flow field vortex (that is, the first gas flow).

Moreover, as shown in FIG. 7, FIG. 8, and FIG. 10, the guide unit N2 can divide the accommodating space N11 into a first space N110 and a second space N111, the first space N110 corresponds to the nebulizer module 1, and the second space N111 corresponds to the control module 2. Moreover, the first gas is introduced into the first space N110 through the portion of the openings N10a and N10b, and the first gas flow is formed between the guiding parts N13, the protruding part N21, and the recessed part N20. The second gas is introduced into the first space N110 through the another one of the openings N10c, and the second gas interacts with the first gas flow to form the second gas flow.

Furthermore, the protruding part N21 has a plurality of first through holes N210, the nebulizer module 1 has a plurality of pin parts 10, and each of the pin parts 10 inserts through the corresponding first through holes N210 and is connected to the control module 2. For example, as shown in FIG. 7 to FIG. 10, the first through holes N210 on the protruding part N21 can provide the pin parts 10 of the nebulizer module 1 to be inserted therethrough. The guide unit N2 can further include a gasket unit N22, the gasket unit N22 can be a waterproof rubber gasket, but the present disclosure is not limited thereto. The gasket unit N22 can be inserted through the first through holes N210 and located between the protruding part N21 and the nebulizer module 1. The gasket unit N22 has a plurality of second through holes N220, and the pin parts 10 of the nebulizer module 1 can be inserted through the second through holes N220. In addition, the nozzle module N further includes a nozzle unit N3, which is detachably connected to the output part N12. The nozzle unit N3 includes a junction part N30 and a divider part N31, and the junction part N30 can be detachably sleeved on the output part N12. Also, the divider part N31 is located inside of the junction part N30, and is parallel and opposite to the guide unit N2. Therefore, the guide unit N2 of the present disclosure can be a structure without any electronic components and circuits, and can be used to prevent the atomized particles provided by the nebulizer module 1 from colliding and condensing into liquid droplets and reaching the control module 2, resulting in the control module 2 being dampened and damaged by moisture.
