Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0006] However, the inventors found that when the fan 13 draws air into the atomizer housing 11 from the heat dissipation inlet 14, the air on both sides of the fan blades will be drawn into the atomizer housing 11 due to the lack of an air duct structure. Figure 2 As shown by the arrow in the figure, the hot air on the right side of the fan blade will be sucked back into the fan blade, forming a small cycle, that is, a vortex, which will cause the heat dissipation airflow noise to increase and the heat dissipation effect to decrease.

[0007] Furthermore, the inventors have found that the heat dissipation inlet 14 and the heat dissipation outlet 15 are arranged on both sides of the atomizer housing 11 , and the mechanical noise generated by the compressor 12 is directly transmitted from both sides of the housing, resulting in loud noise and poor user experience.

[0043] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0044] An embodiment of the present application provides a compression atomizer. Figure 3 This is a three-dimensional view of the compression atomizer of the embodiment of the present application, viewed from the bottom, with a portion of the atomizer housing hidden. Figure 4 yes Figure 3 The compressed atomizer shown is a three-dimensional view observed from the bottom with part of the compressor housing hidden. Figure 5 This is a cross-sectional view of the compression atomizer according to an embodiment of the present application.

[0045] like Figures 3 to 5 As shown, the compression type atomizer 100 includes an atomizer housing 110, a compressor 120 ( Figure 4 、 Figure 5 ) and a fan 130. In addition, the compression atomizer 100 further includes a compressor housing 121 ( Figure 3 、 Figure 5 shown) and fan housing 131 ( Figure 3 、 Figure 5 As shown in FIG, the compressor housing 121 is arranged in the atomizer housing 110 and seals the compressor 120. Thus, the noise generated by the compressor can be effectively isolated and the noise is prevented from spreading outside the atomizer, thereby achieving a noise reduction effect.

[0046] In addition, in the embodiment of the present application, the compressor housing 121 sealing the compressor 120 does not mean complete sealing. For example, a heat dissipation port is provided on the compressor housing 121 .

[0047] In addition, the compressor housing 121 and the fan housing 131 can be formed as one body, thereby reducing the number of components, reducing costs, and improving noise reduction. However, this embodiment of the present application is not limited to this, and the compressor housing 121 and the fan housing 131 can also be formed independently of each other.

[0048] like Figure 3 and Figure 5 As shown, the fan housing 131 is also disposed in the atomizer housing 110 and accommodates the fan 130. Figure 3 , the top of the fan housing 131 is removed.

[0049] like Figure 5As shown, the fan housing 131 has an air inlet 132 and a first heat dissipation outlet 124, and the compressor housing 121 has a first heat dissipation inlet 123. An air duct structure is formed along the first heat dissipation inlet 123, the air inlet 132 and the first heat dissipation outlet 124. Figure 5 As shown by the arrows in FIG, a fixed air duct structure is formed along the first heat dissipation inlet 123 of the compressor housing 121, the air inlet 132 of the fan housing 131, and the first heat dissipation outlet 124 under the guidance of the fan 130. This prevents the heat dissipation airflow from forming vortices and improves the heat dissipation effect.

[0050] In one implementation of the embodiment of the present application, the air inlet 132 of the fan housing 131 is arranged on the side of the fan housing 131 close to the compressor 120, thereby easily forming a fixed air duct structure, further improving the heat dissipation efficiency.

[0051] For example, Figure 5 As shown, the air inlet 132 of the fan housing 131 is disposed at a middle position of the side of the fan housing 131 close to the compressor 120 .

[0052] In one embodiment of the present application, Figure 5 As shown, the atomizer housing 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 housing 131 may overlap with the second heat dissipation outlet 112 of the atomizer housing 110 .

[0053] For example, the first heat dissipation outlet 124 of the fan housing 131 and the second heat dissipation outlet 112 of the atomizer housing 110 are the same opening, or the first heat dissipation outlet 124 and the second heat dissipation outlet 112 are two heat dissipation outlets arranged adjacent to each other along the direction of the heat dissipation path. This can further ensure that the heat dissipation airflow in the compressor housing 121 can be discharged through a single outlet only and will not be re-inhaled into the fan through other paths, thereby further preventing the heat dissipation airflow from forming vortices, improving the heat dissipation effect and reducing the noise generated by the heat dissipation airflow.

[0054] also, Figure 5 It is shown that the first heat dissipation inlet 123 of the compressor housing 121 and the second heat dissipation inlet 111 of the atomizer housing 110 overlap, but the present application is not limited to this. The first heat dissipation inlet 123 and the second heat dissipation inlet 111 may also not overlap. The present application does not limit whether the two overlap and can be set according to actual needs.

[0055] In addition, in the embodiment of the present application, the number 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 is not limited.

[0056] For example, one first heat dissipation inlet 123 , one first heat dissipation outlet 124 , one second heat dissipation inlet 111 , and one second heat dissipation outlet 112 may be provided respectively;

[0057] For another example, a plurality 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.

[0058] In an embodiment of the present application, when there are 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, fixed air duct structures are formed along the multiple second heat dissipation inlets 111, multiple first heat dissipation inlets 123, the air inlet 132, the multiple first heat dissipation outlets 124, and the multiple second heat dissipation outlets 112 respectively.

[0059] In one embodiment of the present application, Figure 5 As shown, the first heat dissipation inlet 123 is arranged at the bottom of the compressor housing 121, the first heat dissipation outlet 124 is arranged at the bottom of the fan housing 131, and the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are arranged at the bottom of the atomizer housing 110. In this way, noise can be prevented from being directly transmitted toward the user, thereby further improving the user experience.

[0060] However, the present application is not limited to this. For example, the first heat dissipation inlet 123 may also be set at the rear of the compressor housing 121, the first heat dissipation outlet 124 may also be set at the rear of the fan housing 131, and the second heat dissipation inlet 111 and the second heat dissipation outlet 112 may also be set at the rear of the atomizer housing 110; or, the first heat dissipation inlet 123 is set at the rear of the compressor housing 121, the first heat dissipation outlet 124 is set at the bottom of the fan housing 131, and the second heat dissipation inlet 111 is set at the rear of the atomizer housing 110, and the second heat dissipation outlet 112 is set at the bottom of the atomizer housing 110; or, the first heat dissipation inlet 123 is set at the bottom of the compressor housing 121, the first heat dissipation outlet 124 is set at the rear of the fan housing 131, and the second heat dissipation inlet 111 is set at the bottom of the atomizer housing 110, and the second heat dissipation outlet 112 is set at the rear of the atomizer housing 110.

[0061] In the embodiment of the present application, "rear" refers to the side of the compressor housing 121 or the atomizer housing 110 that does not face the user when the atomizer is in use. This can also prevent noise from being transmitted directly toward the user, thereby further improving the user experience.

[0062] Figure 6 FIG. 1 is another cross-sectional view of the compression atomizer according to an embodiment of the present application. Figure 6As shown, when the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are arranged at the bottom of the atomizer housing 110, for example, the compression-type atomizer 100 further includes an air guide baffle housing 150, which is arranged outside the bottom of the atomizer housing 110. In addition, there is a gap between the air guide baffle housing 150 and the atomizer housing 110 at the bottom, and at the side or top, to introduce or exhaust airflow.

[0063] In this way, the airflow in and out of the bottom can be guided to the side or top, thereby preventing the bottom from being blocked and causing heat dissipation difficulties. Figure 6 As shown by the arrow in the figure, outdoor air is introduced from the side through the air guide baffle housing 150 and then enters the inside of the atomizer housing 110, the compressor housing 121 and the fan housing 131 from the bottom, and the heat dissipation airflow discharged from the bottom is guided to the side for discharge, thereby preventing the bottom from being blocked and causing heat dissipation difficulties.

[0064] Figure 7 FIG. 1 is another cross-sectional view of the compression atomizer of the embodiment of the present application from another perspective. Figure 7 As shown, the fan 130 is a centrifugal fan that is used to guide the heat dissipation airflow from the interior of the compressor housing 121 and the fan housing 131 to be discharged toward the first heat dissipation outlet 124. In addition, due to the formation of a fixed air duct structure within the compressor housing 121, the embodiment of the present application dissipates heat from the compressor by extracting air outward. Compared with conventional inward blowing heat dissipation methods, this heat dissipation method can further reduce the formation of vortices and further reduce the noise generated by the fan and the heat dissipation airflow.

[0065] In the embodiment of the present application, the blades of the centrifugal fan may be backward-inclined centrifugal blades or forward-inclined blades, or may be radial centrifugal blades.

[0066] Compared with radial centrifugal blades, backward-inclined centrifugal blades or forward-inclined centrifugal blades generate less noise. Moreover, since a fixed air duct structure is formed in the compressor housing 121, noise can be further reduced and heat dissipation effect can be improved.

[0067] In one embodiment of the present application, when the internal gap of the housing is relatively small and heat dissipation is difficult, forward-inclined centrifugal fan blades can be used to achieve greater wind pressure, thereby allowing the heat dissipation airflow to be discharged smoothly. This facilitates product miniaturization while ensuring heat dissipation effectiveness.

[0068] In one embodiment of the present application, Figure 3 As shown, the compression type atomizer 100 may further include a muffler 140. For example, the muffler 140 is disposed on the air intake side of the atomizer 100 to reduce the noise of the air flow entering the compressor on the air intake side.

[0069] Figure 8 This is a schematic diagram of the compression atomizer according to an embodiment of the present application viewed from the front. Figure 9 Schematic diagram of the compression atomizer of the embodiment of the present application viewed from the bottom. Figure 8 and Figure 3 As shown, the atomizer housing 110 has a first air inlet 113 and a first air outlet 114. Figure 9 and Figure 5 As shown, a second heat dissipation inlet 111 and a second heat dissipation outlet 112 are provided at the bottom of the atomizer housing 110 .

[0070] Figure 10 FIG. 1 is another schematic diagram of the compression atomizer of the embodiment of the present application viewed from the bottom. Figure 10 As shown, when the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are arranged at the bottom of the atomizer housing 110, the atomizer housing 110 further has grooves 117 arranged around the second heat dissipation inlet 111 and the second heat dissipation outlet 112. In this way, the heat dissipation efficiency can be improved.

[0071] In the embodiment of the present application, the 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.

[0072] For example, Figure 10 As shown, the groove 117 connects the second heat dissipation inlet 111 and the second heat dissipation outlet 112 and spans the entire bottom of the atomizer housing 110 .

[0073] In one embodiment of the present application, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are recessed inward relative to the bottom surface of the atomizer housing 110. This prevents the heat dissipation outlet from being blocked and further improves heat dissipation efficiency.

[0074] For example, when the bottom surface of the atomizer housing 110 contacts a soft object, if the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are located at the same height as the bottom of the atomizer housing 110, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 may be blocked by the soft object, resulting in poor heat dissipation. In the embodiment of the present application, the second heat dissipation inlet 111 and the second heat dissipation outlet 112 are recessed inward relative to the surface of the bottom of the atomizer housing 110 and a groove 117 is added. This can prevent the second heat dissipation inlet 111 and the second heat dissipation outlet 112 from being blocked, and can allow the heat dissipation airflow to be smoothly discharged along the groove 117, thereby further improving the heat dissipation efficiency.

[0075] Figure 11 Schematic diagram of an embodiment of the muffler of the present application. Figure 11 and Figure 3 As shown, the muffler 140 has a second air inlet 141 and a second air outlet 142 .

[0076] In addition, if Figure 3 As shown, the compressor 120 further has a third air inlet 125 and a third air outlet 126. The first air inlet 113 and the first air outlet 114 of the atomizer housing 110, the second air inlet 141 and the second air outlet 142 of the muffler 140, and the third air inlet 125 and the third air outlet 126 of the compressor 120 can be connected by a silicone tube to form an air path.

[0077] The following will Figure 3 Taking the example of FIG. 1 as an example, the air path structure of the compression atomizer in the embodiment of the present application is described.

[0078] like Figure 3 As shown by the arrows in the figure, the gas enters the second air inlet 141 of the muffler 140 from the first air inlet 113 of the nebulizer housing 110 through the silicone tube, then enters the third air inlet 125 of the compressor 120 from the second air outlet 142 of the muffler 140 through the silicone tube, and then is discharged from the third air outlet 126 of the compressor 120 through the silicone tube to the first air outlet 114 of the nebulizer housing 110. The gas discharged from the first air outlet 114 is, for example, transported to a medicine bottle, thereby atomizing the medicine.

[0079] In one embodiment of the present application, the muffler 140 may be an expansion chamber muffler. The working principle of the expansion chamber muffler can be referred to in related art and will not be described in detail in this application.

[0080] However, in this field, in order to match the frequency of the compressor suction noise, the conventionally designed expansion chamber muffler is relatively long. In a small atomizer, due to the limited internal space of the atomizer, the conventionally designed expansion chamber muffler is difficult to install in the small atomizer unless the volume of the atomizer is increased.

[0081] In the embodiment of the present application, the length of the expansion chamber muffler can be set according to the volume of the atomizer, and the cross-sectional shape of the expansion chamber can also be freely designed according to the shape of the atomizer. Figure 11 As shown, the cross-section of the expansion chamber of the expansion chamber muffler can be a rounded rectangular shape. Thus, when the muffler frequency does not completely match the noise frequency, the muffler effect can be satisfied by increasing the expansion ratio. However, this application is not limited to this. While ensuring the cross-sectional area of ​​the expansion chamber, the cross-sectional shape of the expansion chamber can be designed according to actual conditions.

[0082] In addition, the air inlet and outlet of the muffler can be arranged on the same side of the muffler, for example Figure 11As shown, the second air inlet 141 and the second air outlet 142 are arranged on the same side of the muffler 140. In this way, the internal space of the atomizer housing can be utilized to the maximum extent.

[0083] In addition, the inner diameters of the muffler's air inlet and outlet can be determined based on tests while ensuring the muffler effect and not affecting the compressor's air intake flow.

[0084] Figure 12 FIG is a schematic diagram of another embodiment of the muffler of the present application. Figure 12 As shown, the second air inlet 141 and the second air outlet 142 of the muffler 140 may also be disposed on opposite sides of the muffler 140 .

[0085] In one embodiment of the present application, the muffler 140 and the compressor housing 110 can be formed as one piece. This reduces the number of components while ensuring noise reduction, thereby reducing costs. Furthermore, the muffler 140 and the compressor housing 110 can also be designed as separate pieces. This application does not restrict the location of the muffler; the muffler can be freely placed within the atomizer housing.

[0086] Figure 13 It is a schematic diagram of an implementation of a compressor housing according to an embodiment of the present application.

[0087] like Figure 8 and Figure 9 As shown, the atomizer housing 110 may include a first upper housing 115 and a first lower housing 116. Figure 13 As shown, the compressor housing 121 may include a second upper housing 127 and a second lower housing 128 .

[0088] Furthermore, the first lower housing 116 of the atomizer housing 110 can be integrally formed with the second lower housing 128 of the compressor housing 121. This reduces noise while further improving heat dissipation due to the reduction of one housing layer. Furthermore, the first lower housing 116 of the atomizer housing 110 and the second lower housing 128 of the compressor housing 121 are formed as a single component, reducing the number of components and thus lowering costs.

[0089] It can be seen from the above embodiments that by sealing the compressor through the compressor housing, the mechanical noise generated by the compressor can be effectively isolated from spreading outside the atomizer, thereby achieving a noise reduction effect; in addition, the compressor housing also seals the fan, so that through the fan, a single heat dissipation path is formed between the heat dissipation inlet and the heat dissipation outlet of the compressor housing, thereby avoiding the formation of vortices in the heat dissipation airflow, thereby improving the heat dissipation effect and reducing the noise generated by the heat dissipation airflow.

[0090] The present application has been described above in conjunction with specific embodiments. However, those skilled in the art should understand that these descriptions are merely illustrative and are not intended to limit the scope of protection of the present application. Those skilled in the art may make various modifications and variations to the present application based on the spirit and principles of the present application, and such modifications and variations are also within the scope of the present application.
