Description

The present invention relates to the field of medical devices, and in particular to compressed atomizers.

In clinical medicine, using an atomizer to treat patients suffering from respiratory diseases is a common treatment method. Here, compression type atomizers are widely used as nebulizers, for example, as described in Patent Document 1 (JP Patent Publication 2022-98193).

JP 2022-98193 A

Figure 1 is an oblique view of a conventional compression atomizer with its upper case removed, viewed from diagonally above, and Figure 2 is a cross-sectional view of the conventional compression atomizer.

1 and 2, a compression type atomizer 10 includes an atomizer case 11, a compressor 12, and a fan 13, and a heat dissipation inlet 14 and a heat dissipation outlet 15 are provided on both sides of the atomizer case 11. In this compression type atomizer 10, air is drawn into the atomizer case 11 from the heat dissipation inlet 14 by the fan 13, and then the air is discharged through the heat dissipation outlet 15, thereby dissipating heat from the compressor 12.

The above explanation is provided to allow a person skilled in the art to clearly and completely understand the technical solution of the present invention. These explanations are not recognized by a person skilled in the art.

However, the inventors have discovered that when the fan 13 draws air into the atomizer case 11 from the heat dissipation inlet 14, due to the lack of an air passage structure, the air on both sides of the fan blade is drawn in by the fan blade, and as shown by the arrow X in Figure 2, the hot air on the right side of the fan blade is re-drawn into the fan blade, forming a small circulation, i.e., a vortex, which increases the noise of the heat dissipation airflow and reduces the heat dissipation effect.

The inventors have further discovered that because the heat dissipation inlet 14 and the heat dissipation outlet 15 are provided on both sides of the atomizer case 11, mechanical noise generated in the compressor 12 is directly propagated from both sides of the case, resulting in increased noise and a poor user experience.

Therefore, the objective of this invention is to provide a compression type atomizer that can effectively reduce noise caused by heat dissipation airflow, improve heat dissipation effect, and also effectively reduce mechanical noise propagating outside the atomizer, thereby improving user experience.

A preferred embodiment of the present invention is described with reference to the drawings.

An embodiment of the present invention provides a compression type atomizer. Fig. 3 is a perspective view of the compression type atomizer 100 according to the embodiment of the present invention, viewed from diagonally below, with the atomizer case partially removed. Fig. 4 is a perspective view of the compression type atomizer 100 shown in Fig. 3, viewed from diagonally below, with the compressor case further partially removed. Fig. 5 is a cross-sectional view of the compression type atomizer 100 according to the embodiment of the present invention.

As shown in Figures 3 to 5, the compression type atomizer 100 includes an atomizer case 110, a compressor 120 (shown in Figures 4 and 5), and a fan 130. The compression type atomizer 100 further includes a compressor case 121 (shown in Figures 3 and 5) and a fan case 131 (shown in Figures 3 and 5). The compressor case 121 is provided within the atomizer case 110 and surrounds and houses the compressor 120. This effectively blocks noise generated by the compressor and prevents the noise from diffusing outside the atomizer case 110, thereby achieving a noise reduction effect.

In addition, in the embodiments of the present invention, the compressor case 121 surrounding and housing the compressor 120 does not mean that the compressor case 121 houses the compressor 120 in a completely sealed manner; for example, the compressor case 121 may be provided with a heat dissipation port (in this example, a heat dissipation inlet and a heat dissipation outlet).

The compressor case 121 and the fan case 131 may also be formed as a single unit. This reduces the number of parts, lowers costs, and improves noise reduction. However, the embodiment of the present invention is not limited to this, and the compressor case 121 and the fan case 131 may also be formed independently of each other.

3 and 5, a fan case 131 is also provided within the atomizer case 110 to house the fan 130. In FIG. 3, for ease of understanding, the top of the fan case 131 is removed.

As shown in FIG. 5, the fan case 131 has an intake port 132 and a first heat dissipation outlet 124, and the compressor case 121 has a first heat dissipation inlet 123. An air passage structure for dissipating heat from the compressor 120 is formed along the first heat dissipation inlet 123, the intake port 132, and the first heat dissipation outlet 124. For example, as shown by arrow A in FIG. 5, a predetermined air passage structure is formed along the first heat dissipation inlet 123 of the compressor case 121, the intake port 132, and the first heat dissipation outlet 124 of the fan case 131 through the guidance of the fan 130. This makes it possible to avoid the formation of a vortex by the heat dissipation airflow, and also improves the heat dissipation effect.

In an embodiment of the present invention, the air intake 132 of the fan case 131 is provided on the side of the fan case 131 adjacent to and facing the compressor 120. This makes it easy to form a predetermined air passage structure and further improves heat dissipation efficiency.

For example, as shown in FIG. 5, the intake port 132 of the fan case 131 is provided at a central position on an adjacent side of the fan case 131 facing the compressor 120.

In an embodiment of the present invention, as shown in FIG. 5, the atomizer case 110 has a second heat dissipation inlet 111 and a second heat dissipation outlet 112, and the first heat dissipation outlet 124 of the fan case 131 may overlap with the second heat dissipation outlet 112 of the atomizer case 110 to be capable of fluid communication.

For example, the first heat dissipation outlet 124 of the fan case 131 and the second heat dissipation outlet 112 of the atomizer case 110 may be the same opening, or instead, the first heat dissipation outlet 124 and the second heat dissipation outlet 112 may be two heat dissipation outlets adjacent to each other in a direction along the heat dissipation path. This further ensures that the heat dissipation airflow in the compressor case 121 is discharged only through a single outlet and is not re-absorbed by the fan through another path. Furthermore, it is possible to further avoid the formation of a vortex by the heat dissipation airflow, improve the heat dissipation effect, and reduce the noise generated by the heat dissipation airflow.

5 shows that the first heat dissipation inlet 123 of the compressor case 121 and the second heat dissipation inlet 111 of the atomizer case 110 overlap, the present invention is not limited to this, and the first heat dissipation inlet 123 and the second heat dissipation inlet 111 do not have to overlap. The present invention can be set according to actual needs without being limited to whether the two overlap.

Furthermore, in the embodiments of the present invention, the numbers of the first heat dissipation inlet 123, the first heat dissipation outlet 124, the second heat dissipation inlet 111, and the second heat dissipation outlet 112 are not limited.

For example, only one each of the first heat dissipation inlet 123, the first heat dissipation outlet 124, the second heat dissipation inlet 111, and the second heat dissipation outlet 112 may be provided.

Furthermore, for example, multiple first heat dissipation inlets 123, multiple first heat dissipation outlets 124, multiple second heat dissipation inlets 111, and multiple second heat dissipation outlets 112 may be provided.

In an embodiment of the present invention, when a plurality of first heat dissipation inlets 123, a plurality of first heat dissipation outlets 124, a plurality of second heat dissipation inlets 111 and a plurality of second heat dissipation outlets 112 are provided, the plurality of second heat dissipation inlets 111, the plurality of first heat dissipation inlets 123, the air intake 132, the plurality of first heat dissipation outlets 124 and the plurality of second heat dissipation outlets 112 each form a predetermined air path structure.

5, in an embodiment of the present invention, the first heat dissipation inlet 123 is provided at the bottom of the compressor case 121, the first heat dissipation outlet 124 is provided at the bottom of the fan case 131, and the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are provided at the bottom of the atomizer case 110. This can prevent noise from being transmitted directly to the user, further improving the user experience.

However, the present invention is not limited to this. For example, the first heat dissipation inlet 123 may be provided at the rear of the compressor case 121, the first heat dissipation outlet 124 may be provided at the rear of the fan case 131, and accordingly, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 may be provided at the rear of the atomizer case 110. Alternatively, the first heat dissipation inlet 123 may be provided at the rear of the compressor case 121, the first heat dissipation outlet 124 may be provided at the bottom of the fan case 131, and accordingly, the second heat dissipation inlet 111 may be provided at the rear of the atomizer case 110, and the second heat dissipation outlet 112 may be provided at the bottom of the atomizer case 110. Alternatively, the first heat dissipation inlet 123 may be provided at the bottom of the compressor case 121, the first heat dissipation outlet 124 may be provided at the rear of the fan case 131, and accordingly, the second heat dissipation inlet 111 may be provided at the bottom of the atomizer case 110, and the second heat dissipation outlet 112 may be provided at the rear of the atomizer case 110.

In the embodiment of the present invention, the "rear" refers to the side of the compressor case 121 or the atomizer case 110 that does not face the user when the atomizer is in use. This prevents noise from being transmitted directly to the user, thus further improving the user experience.

6 is another cross-sectional view of a compression type atomizer 100 according to an embodiment of the present invention. As shown in FIG. 6, when the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are provided at the bottom of the atomizer case 110, for example, the compression type atomizer 100 further includes an air guide baffle case 150. In this example, the air guide baffle case 150 is provided on the outside of the bottom of the atomizer case 110. In addition, there is a gap at the bottom between the air guide baffle case 150 and the atomizer case 110, and a gap at the side or top to introduce or exhaust airflow.

This allows the airflow coming in and out of the bottom to be guided to the side or top, preventing the bottom from being blocked and making it difficult to dissipate heat. As shown by arrow B1 in Figure 6, the air guide baffle case 150 allows outdoor air to be introduced from the side, and then, as shown by arrow B2, it can be introduced into the atomizer case 110, compressor case 121, and fan case 131 from the bottom. Also, as shown by arrows B3 and B4, the heat dissipating airflow discharged from the bottom can be guided to the side and discharged. This prevents the bottom from being blocked and making it difficult to dissipate heat.

7 is a cross-sectional view of a compression type atomizer 100 according to an embodiment of the present invention from another perspective. As shown in FIG. 7, the fan 130 is a centrifugal fan for guiding the heat dissipation airflow to be discharged from the inside of the compressor case 121 and the fan case 131 to the first heat dissipation outlet 124. In addition, since a predetermined air passage structure is formed inside the compressor case 121, the embodiment of the present invention has a heat dissipation method for the compressor that exhausts air to the outside. This heat dissipation method can further reduce the formation of vortexes and further reduce noise caused by the fan and the heat dissipation airflow compared to the conventional heat dissipation method of sending air inside.

In an embodiment of the present invention, the fan blades of the centrifugal fan may be backward-inclined centrifugal fan blades or forward-inclined fan blades, or may be radial centrifugal fan blades.

Compared to the noise generated by radial centrifugal fan blades, the noise generated by backward inclined centrifugal fan blades or forward inclined fan blades is lower. In addition, since a predetermined air passage structure is formed inside the compressor case 121, the noise can be further reduced and the heat dissipation effect can be improved.

In the embodiment of the present invention, when the gap inside the case is small and heat dissipation is difficult, a forward-inclined fan blade is used to obtain a larger wind pressure, which allows the heat dissipation airflow to be discharged smoothly. This is advantageous for miniaturizing the product while ensuring the heat dissipation effect.

In an embodiment of the present invention, as shown in Figure 3, the compression atomizer 100 may further include a silencer 140. For example, the silencer 140 is provided on the intake side of the compression atomizer 100. This can reduce the noise of the airflow entering the compressor on the intake side.

Figure 8 is a perspective view of a compression type atomizer 100 according to an embodiment of the present invention, viewed from diagonally above its front surface. Figure 9 is a perspective view of a compression type atomizer 100 according to an embodiment of the present invention, viewed from diagonally below its bottom surface. As shown in Figures 8 and 3, a first intake port 113 and a first exhaust port 114 are provided at the top of the atomizer case 110. As shown in Figures 9 and 5, a second heat dissipation inlet 111 and a second heat dissipation outlet 112 are provided at the bottom of the atomizer case 110.

10 is another perspective view of the compression type atomizer 100 according to an embodiment of the present invention, viewed from diagonally below its bottom surface. As shown in FIG. 10, when the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are provided at the bottom of the atomizer case 110, the atomizer case 110 further includes a groove 117 provided around the second heat dissipation inlet 111 and the second heat dissipation outlet 112. This can improve the heat dissipation efficiency.

In an embodiment of the present invention, a groove 117 is provided around the second heat dissipation inlet 111 and the second heat dissipation outlet 112, and its specific shape and size can be designed according to actual needs.

For example, as shown in FIG. 10, a groove 117 connects the second heat dissipation inlet 111 and the second heat dissipation outlet 112 and spans the entire bottom of the atomizer case 110.

In an embodiment of the present invention, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are recessed inward (upward) relative to the surface of the bottom of the atomizer case 110. This makes it possible to prevent the heat dissipation outlets (in this example, the heat dissipation inlet and the heat dissipation outlet) from being blocked, thereby further improving the heat dissipation efficiency.

For example, when the bottom surface of the atomizer case 110 comes into contact with a flexible object, if the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are at the same height as the bottom of the atomizer case 110, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 may be blocked by the flexible object, making it difficult to dissipate heat. In the embodiment of the present invention, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are recessed inward (upward) relative to the surface of the bottom of the atomizer case 110 to add a groove 117. This makes it possible to avoid the second heat dissipation inlet 111 and the second heat dissipation outlet 112 being blocked. In addition, the heat dissipation airflow is smoothly discharged along the groove 117, further improving the heat dissipation efficiency.

11 is a diagram of an example of a silencer included in the compression type atomizer 100 according to an embodiment of the present invention. As shown in FIG. 11 and FIG. 3, the silencer 140 has a second intake port 141 and a second exhaust port 142.

3, the compressor 120 further includes a third intake port 125 and a third exhaust port 126. The first intake port 113 and the first exhaust port 114 of the atomizer case 110, the second intake port 141 and the second exhaust port 142 of the silencer 140, and the third intake port 125 and the third exhaust port 126 of the compressor 120 are connected by a silicone tube. This allows a gas path to be formed.

Below, the gas path structure of a compression type atomizer according to an embodiment of the present invention is explained using Figure 3 as an example.

As shown by arrows G1 and G2 in FIG. 3, gas passes through the silicone tube from the first intake port 113 of the atomizer case 110 and enters the second intake port 141 of the silencer 140, and then passes through the silicone tube from the second exhaust port 142 of the silencer 140 and enters the third intake port 125 of the compressor 120 as shown by arrows G3 and G4, and is compressed by the compressor 120. Arrows G1 to G4 indicate the intake side gas path. Next, the gas discharged by the compressor 120 passes through the silicone tube from the third exhaust port 126 of the compressor 120 as shown by arrows G5 and G6, and is discharged outside the atomizer case 110 through the first exhaust port 114 of the atomizer case 110. Arrows G5 to G6 indicate the exhaust side gas path. The gas discharged from the first exhaust port 114 is transported to, for example, a liquid medicine bottle (not shown), thereby atomizing the liquid medicine.

In an embodiment of the present invention, the silencer 140 may be an expansion chamber type silencer. The operating principle of an expansion chamber type silencer is well known and will not be described in detail in this specification.

However, in this field, in order to match the frequency of the compressor intake noise, the length of the designed expansion chamber type silencer is increased. In a small atomizer, the internal space of the atomizer is limited, so it is difficult to fit such a designed expansion chamber type silencer into the small atomizer unless the volume of the atomizer is expanded.

In the embodiment of the present invention, the length of the expansion chamber type silencer may be set according to the atomizer volume, and the cross-sectional shape of the expansion chamber may be freely designed according to the shape of the atomizer. For example, as shown in FIG. 11, the cross section of the expansion chamber of the expansion chamber type silencer may be a rectangle with rounded corners. In this way, when the silencing frequency and the noise frequency do not perfectly match, the silencing effect can be satisfied by increasing the expansion ratio. However, the present application is not limited to this, and when the size of the cross-sectional area of the expansion chamber is ensured, the cross-sectional shape of the expansion chamber can be designed according to the actual situation.

The silencer intake and exhaust ports may be provided on the same side of the silencer. For example, as shown in FIG. 11, a second intake port 141 fluidly connected to the upstream portion of the intake side gas path (portion indicated by arrow G2 in FIG. 3) and a second exhaust port 142 fluidly connected to the downstream portion of the intake side gas path (portion indicated by arrow G3 in FIG. 3) may be provided on the same side of the silencer 140. This allows the internal space of the atomizer case to be used to the maximum.

In addition, the inner diameter of the silencer's intake and exhaust ports can be obtained based on testing to ensure sound-absorbing effect while not affecting the intake flow rate of the compressor.

12 is a diagram of another example of a silencer included in the compression type atomizer 100 according to an embodiment of the present invention. As shown in FIG. 12, the second intake port 141 and the second exhaust port 142 of the silencer 140 may be provided on opposite sides of the silencer 140.

In an embodiment of the present invention, the silencer 140 may be formed integrally with the compressor case 121. This ensures a noise reduction effect and reduces the number of parts, thereby reducing costs. The silencer 140 and the compressor case 121 may also be designed separately. The present invention does not limit the position of the silencer, and the silencer may be freely positioned within the atomizer case.

Figure 13 is a diagram of an example of a compressor case included in a compression type atomizer 100 according to an embodiment of the present invention.

8 and 9, the atomizer case 110 may include a first upper case 115 and a first lower case 116. As shown in FIG. 13, the compressor case 121 may include a second upper case 127 and a second lower case 128.

The first lower case 116 of the atomizer case 110 may be integrally formed with the second lower case 128 of the compressor case 121. This ensures a noise reduction effect and reduces one case layer, further improving the heat dissipation effect. The first lower case 116 of the atomizer case 110 and the second lower case 128 of the compressor case 121 are formed as a single member, thereby reducing the number of parts and reducing costs.

As can be seen from the above-mentioned embodiment, the compressor case surrounds and houses the compressor, thereby effectively blocking the mechanical noise generated by the compressor from diffusing outside the atomizer, thereby achieving a noise reduction effect. Furthermore, the compressor case may also surround and house the fan, allowing the fan to form a single heat dissipation path between the heat dissipation inlet and heat dissipation outlet of the compressor case. This makes it possible to avoid the formation of a vortex by the heat dissipation airflow, improve the heat dissipation effect, and reduce noise caused by the heat dissipation airflow.

The present invention has been described above with reference to specific embodiments, but the above description is merely illustrative and does not limit the scope of protection of the present invention. Various modifications and changes may be made to the present invention without departing from the spirit and principles of the present invention, and these modifications and changes also fall within the scope of the present invention.

The above-mentioned multiple embodiments can each be realized independently, but the embodiments can also be combined with each other. Also, the various features in the different embodiments can each be realized independently, but the features in the different embodiments can also be combined with each other.
