[0041] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0042] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0043] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0045] In order to solve the problems of complex structure, inconvenience in mold opening and manufacturing of atomizer nozzles, the utility model provides an atomizer nozzle. By splitting the atomizer nozzle into an air intake seat, a first component and a second component, and using a shell to wrap the first component and the second component, the manufacturing and assembly of each part are more convenient. The air intake seat is used to install a high-pressure air pump, and the high-pressure gas in the high-pressure air pump is passed into the second component, and the essential oil at the atomization port position of the second component is blown away to form atomized essential oil, which is then discharged into the external environment through the first component. In addition, the diameters of the first component and the second component gradually decrease from the end adjacent to the end of the shell toward the end adjacent to the middle of the shell, making it easier to demold and install the first component and the second component.

[0046] like Figures 1 to 4 As shown, the atomizer nozzle 100 includes a housing 110, a nozzle assembly 120 mounted within the housing 110, and an air inlet seat 130 mounted on the sidewall of the housing 110. The air inlet seat 130 is used to connect to an air pump, which allows high-pressure gas from the air pump to enter the nozzle assembly 120. The nozzle assembly 120 is open at both ends, with the bottom end being used to mount an essential oil bottle. Atomized essential oil is discharged from the top of the nozzle assembly 120.

[0047] like Figure 5 As shown, the housing 110 is cylindrical, and the nozzle assembly 120 is also cylindrical. In this embodiment, the housing 110 is made of aluminum, and the nozzle assembly 120 is made of plastic. The surface of the aluminum housing is not only more aesthetically pleasing than that of a plastic housing, but also makes it easier and more convenient to install the nozzle assembly 120 within the housing 110.

[0048] In order to simplify the manufacturing, the nozzle assembly 120 is divided into two parts: a first assembly 121 and a second assembly 122. The first assembly 121 is installed on the upper part of the housing 110, and the second assembly 122 is installed on the lower part of the housing 110. The first assembly 121 is fixed on the second assembly 122. Figure 4 The first and second components 121, 122 are cylindrical in shape. The diameter of the first component 121 gradually decreases from the top of the housing 110 toward the middle of the housing 110, while the diameter of the second component 122 gradually decreases from the bottom of the housing 110 toward the middle of the housing 110. Although the diameter of the first and second components 121, 122 at the ends near the middle of the housing 110 is not significantly reduced compared to the diameter at the ends near the ends of the housing 110, this design makes the first and second components 121, 122 easy to demold and install within the housing 110.

[0049] In order to ensure that the first component 121 and the second component 122 are more firmly installed in the housing 110 and prevent rotation, two long strip-shaped positioning strips 111 are provided on the inner wall of the housing 110, and two long strip-shaped positioning grooves 123 are provided on the circumferential side walls of the first component 121 and the second component 122. The positioning grooves 123 are engaged with the positioning strips 111, so that the first component 121 and the second component 122 are snap-fitted into the housing 110. It should be noted that the number and position of the positioning strips 111 and the positioning grooves 123 are not limited and can be set as needed.

[0050] Illustratively, this embodiment further provides a plurality of ribs 122a on the circumferential side walls of the second component 122, which not only strengthen the strength of the entire atomizer nozzle 100 and prevent the first component 121 and the second component 122 from being sunken and elastically deformed near the connection point in the shell 110; but also improves the dimensional tolerance of the atomizer nozzle 100 during manufacturing, making the shell 110 and the nozzle assembly 120 easy to match and install.

[0051] like Figure 4 and Figure 6As shown, the first component 121 is similar to the cover body, including a top wall 1210 and circumferential side walls 1211. A threaded groove 1212 is provided in the center of the top wall 1210 for mounting a nozzle or nozzle cover, thereby discharging the atomized essential oil flowing through the first component 121 into the external environment. The gap below the top wall 1210 communicates with the threaded groove 1212, forming a first airflow channel 1213. A groove 1214 and a retaining groove 1215 are provided at the bottom of the first component 121. The top of the second component 122 is provided with a flange 1220 and a protrusion 1221. The flange 1220 mates with the groove 1214, and the protrusion 1221 mates with the retaining groove 1215. In addition, the first component 121 is provided with four countersunk holes 1216 along the circumference of the top wall, and the second component 122 is provided with four fixing columns 1222. Screws are passed through the countersunk holes 1216 and tightened in the fixing columns 1222, so that the first component 121 and the second component 122 are installed more firmly.

[0052] like Figure 4 and Figure 7 As shown, the bottom inner wall of the second component 122 is provided with a threaded groove 1223 for screwing the essential oil bottle onto the second component 122. A base plate 1224 is provided within the second component 122, with an atomization port 124 located below the base plate 1224. A slot 1225 is provided on the base plate 1224, and the gap between the fixing posts 1222 communicates with the slot 1225, forming a second airflow channel 1226. The first airflow channel 1213 within the first component 121 and the second airflow channel 1226 within the second component 122 are connected to form a demisting channel. Atomized essential oil near the atomization port 124 is discharged into the external environment through the second airflow channel 1226 and the first airflow channel 1213.

[0053] The circumferential sidewalls of the second assembly 122 are provided with threaded holes 1227 and air inlet holes 1228. Fasteners are used to secure the air inlet seat 130 to the second assembly 122 through the threaded holes 1227. A third airflow channel 1229 is also provided within the second assembly 122. One end of the third airflow channel 1229 communicates with the air inlet hole 1228, while the other end extends through the bottom plate 1224 to the underside of the bottom plate 1224, forming the atomization port 124. The third airflow channel 1229 and the air inlet hole 1228 are connected to the airflow channel within the air inlet seat 130. The high-pressure gas introduced into the air inlet seat 130 passes through the air inlet hole 1228 and the third air flow channel 1229 and is blown out from the atomization port 124. According to the siphon principle, the high-pressure gas blown out from the atomization port 124, on the one hand, causes the essential oil in the essential oil bottle to be sucked out to the vicinity of the atomization port 124 through the conduit; on the other hand, the high-pressure gas blows away the essential oil on the conduit near the atomization port 124, causing it to be atomized, forming atomized essential oil.

[0054] In one example, a buckle plate 140 buckled onto the bottom plate is further provided, and a first slot hole 141 and a second slot hole 142 are provided on the buckle plate 140. The first slot hole 141 and the second slot hole 142 form a channel through which the essential oil passes when it is discharged upward after atomization.

[0055] like Figure 3 and Figure 4 As shown, in this embodiment, the air inlet seat 130 includes a seat body 131, a bottom cover 132, and an air pump connector 133. The air pump connector 133 is a hollow cylinder. The bottom cover 132 is buckled onto the bottom wall of the base 131, and the air pump connector 133 is installed in the seat body 131. A fourth air flow channel 134 is provided in the seat body 131, and an air pump communication port 1321 is provided on the bottom cover 132. The fourth air flow channel 134, the air pump connector 133, and the air pump communication port 1321 form an air flow channel of the air inlet seat 130, which is connected to the air inlet hole 1228 of the second component 122.

[0056] In order to enhance the rigidity of the nozzle assembly 120, a third assembly 125 is further provided. The third assembly 125 is installed in the second assembly 122. Figure 8 As shown, the first end of the third component 125 is a support plate 1251, and the second end is a support column 1252. The bottom wall of the support plate 1251 is circumferentially provided with four through-holes 1253. After the four fixing columns 1222 of the second component 122 are inserted into the four through-holes 1253, the support plate 1251 is pressed and installed within the second component 122. In other words, the sidewalls of the support plate 1251 abut against the inner wall of the second component 122 using an interference fit. The support columns 1252 are provided with four arcuate grooves 1254. These grooves 1254 mate with the fixing columns 1222 of the second component 122, providing clearance relative to the fixing columns 1222 when the third component 125 is installed within the second component 122. The support columns 1252 also have notches 1255 for the pipe wall forming the third airflow channel 1229 to pass through. By setting up the third component 125, the first component 121 can be supported, and the side wall of the support plate 1251 can also enhance the rigidity of the side wall of the top of the second component 122, thereby avoiding the situation where the top of the nozzle 122 is not rigid enough and is prone to depression or deformation.

[0057] In summary, the present invention disassembles the previously complex nozzle assembly into a first component, a second component, and an air inlet seat, encloses the first and second components in a housing, and makes the outer diameters of the first and second components at the middle end of the housing smaller than those at the end of the housing, facilitating manufacturing and installation. To account for the potential for insufficient rigidity and sag in the middle of the housing, ribs are provided on the circumferential sidewalls of the second component, and a third component is provided within the second component. The provision of ribs further increases the dimensional tolerance between the second component and the housing, facilitating manufacturing.

[0058] Based on any of the above atomizer nozzles, the present invention also provides an atomizer 200, such as Figures 9 to 11 As shown, it includes a nozzle cover assembly 210, a container bottle (not shown in the figure), an air pump (not shown in the figure) and any one of the above-mentioned atomizer nozzles 100, the container bottle is installed on the second component 122, the air pump is installed at the bottom end of the air inlet seat 130, the nozzle cover assembly 210 is installed on the first component 121, and a cover plate 220 is provided between the nozzle cover assembly 210 and the first component 121. The top of the nozzle cover assembly 210 is a mist exhaust port 211, and the mist exhaust port 211 is connected to the mist exhaust channel in the atomizer nozzle 100. It should be noted that although the container bottle in this embodiment is an essential oil bottle, it is not limited to an essential oil bottle, and can also be filled with liquids with other functions for use in other application scenarios.

[0059] Specifically, in this embodiment, the nozzle cover assembly 210 includes a spray plug 212 and a nozzle 213. The spray plug 212 is threadedly connected to the threaded groove 1212, and the nozzle 213 is threadedly connected to the spray plug 212. The nozzle 213 and the spray plug 212 both have through-holes in their centers. After passing through the mist discharge channel, the atomized essential oil is discharged to the external environment through the spray plug 212 and the nozzle 213.

[0060] The above embodiments are not exhaustive of the present invention, and there may be many other embodiments not listed. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
