Description

Technical Field

[0001] This application relates to a cylinder connection structure, particularly a cylinder connection structure for an aroma diffuser and an aroma diffuser using the cylinder connection structure. Background Technology

[0002] In order to obtain a relatively comfortable living and working environment, people use aromatherapy devices to diffuse essential oils into the environment.

[0003] Aroma diffusers, or similar devices, function by atomizing essential oils into tiny particles and then dispersing these particles into the environment to create a comfortable fragrance and enhance living and working conditions. These diffusers typically consist of multiple cylinders, each with different functions. For example, some cylinders hold the essential oil bottles, while others house the atomizing mechanism. The cylinders need to be securely connected; however, current connections usually use threaded joints. When the cylinder walls are thin, implementing threaded connections is difficult, and threaded joints require a certain thickness of sidewall. Therefore, finding a simple and easy-to-assemble connection method for thin-walled cylinders is a problem that needs improvement in this field. Utility Model Content

[0004] The purpose of this application is to provide a simplified connection structure to solve one or more of the above-mentioned technical problems; another purpose of this application is to provide an aromatherapy device.

[0005] To meet any technical objective or solve any technical problem of this application, the following technical solution is adopted:

[0006] A cylindrical connection structure includes a lower cylinder and an upper cylinder. The lower cylinder has a side wall, and the top edge of the side wall is provided with a plurality of first inserts and a plurality of second inserts. The plurality of first inserts and the plurality of second inserts are alternately spaced, and each first insert has a slot. The upper cylinder has an inner side wall, and the inner side wall is provided with barbs that can engage with the slots. There are a plurality of barbs, each corresponding to one of the plurality of first inserts. The upper cylinder has a partition wall, and the partition wall is provided with a plurality of protruding ribs. Each protruding rib forms an insertion slot with the inner side wall. When the upper cylinder and the lower cylinder are connected, the slots engage with the barbs, and the second inserts are inserted into the insertion slots.

[0007] Furthermore, the number of the first insert and the second insert are both three, and they are arranged alternately at intervals.

[0008] Furthermore, a cover and a fog outlet plug are provided. The cover is connected to the upper cylinder and the cover body. The cover body has a fog outlet hole, and the fog outlet plug is inserted into the fog outlet hole.

[0009] To meet another technical objective of this application or any of the technical problems to be solved, the following technical solution is adopted:

[0010] An aromatherapy diffuser, characterized in that it includes a cylinder connecting structure, an atomizing core, an essential oil bottle, and a suction tube; the upper cylinder is provided with an atomizing core seat, the atomizing core is installed on the atomizing core seat, the upper cylinder has an air inlet channel communicating with the atomizing core seat, and an air inlet plug is provided to be inserted into the air inlet channel; the upper cylinder is provided with a first connecting end that is connected to the suction tube and communicates with the atomizing core seat.

[0011] Furthermore, the upper cylinder is provided with a second connecting end that connects to the essential oil bottle, and the lower cylinder has a space for accommodating the essential oil bottle.

[0012] Furthermore, the opening of the essential oil bottle is a threaded opening, and the second connecting end is a threaded opening and is threadedly connected to the opening of the essential oil bottle.

[0013] Furthermore, the atomizing core has a liquid inlet, an air inlet, a liquid spraying port, and an air spraying port; the atomizing core seat has a liquid inlet end connected to the liquid suction tube, an air inlet end connected to the air intake channel, a liquid outlet connected to the liquid inlet of the atomizing core, and an air outlet connected to the air inlet of the atomizing core.

[0014] Furthermore, the atomizing core has an air inlet platform and a liquid inlet slope, the air jet is located on the air inlet platform, the liquid jet is located on the liquid inlet slope, and the central axis of the liquid jet forms an angle with the axis of the air jet.

[0015] Furthermore, the axis of the jet nozzle is perpendicular to the horizontal plane.

[0016] Furthermore, the included angle is 90 to 170 degrees.

[0017] Compared with existing technologies, the advantages of this application are as follows: The cylinder connection structure employs a lower cylinder with a snap-fit ​​insert and an upper cylinder with a barb. The snap-fit ​​insert and barb engage to securely connect the upper and lower cylinders. Furthermore, the lower cylinder's snap-fit ​​insert engages with the upper cylinder's slot to further secure the connection. The alternating arrangement of these two types of snap-fit ​​inserts further strengthens the connection. When the cylinder is thin-walled, the conventional threaded connection can be avoided, allowing for a secure connection of the thin-walled cylinder. This application's cylinder connection structure, through the snap-fit ​​of the first snap-fit ​​insert and the barb, and the insertion of the second snap-fit ​​insert into the slot, allows the upper and lower cylinders to be fixed axially after insertion, eliminating the need for rotational engagement and simplifying assembly. Since this structure does not rely on a continuous threaded structure on the cylinder sidewall, it can achieve connection even with thin sidewalls, making it suitable for structural designs with limited wall thickness. The first and second inserts are alternately spaced, so that the connecting parts are distributed circumferentially, which helps to improve the stability of the connection. This application also includes an aromatherapy diffuser that uses the above-mentioned cylindrical connecting structure, which has an atomizing device in the upper cylinder and an essential oil bottle in the lower cylinder. When the aromatherapy diffuser is assembled, the upper cylinder is connected to the lower cylinder, and the aromatherapy diffuser is assembled by the cylindrical connecting structure it adopts.

[0035] The embodiments of this application are described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0036] For typical embodiments of this application, please see Figures 1 to 3 As shown, this application discloses a cylindrical connection structure, including an upper cylinder 10 and a lower cylinder 20. This cylindrical connection structure enables a tight and convenient connection between the upper cylinder 10 and the lower cylinder 20, especially when the side walls of the cylinders are thin, i.e., the side walls of the upper cylinder 10 and the lower cylinder 20 are thin. The cylindrical connection structure of this application can better achieve a tight and convenient connection between the upper cylinder 10 and the lower cylinder 20. First, the lower cylinder 20 has a side wall 23, from... Figure 2 As can be seen, the sidewall 23 has a top edge 231, on which multiple inserts are provided, including a first insert 21 and a second insert 22. The two types of inserts are alternately arranged, that is, the two sides of any first insert 21 are the second insert 22, and similarly, the two sides of any second insert 22 are the first insert 21. The first insert 21 has a slot 210. Figure 3 As shown, the upper cylinder 10 has a latch 210 corresponding to the barb 11, and similarly, the upper cylinder 10 has a rib 12 corresponding to the second insert 22. The rib 12 and the inner sidewall 14 of the upper cylinder 10 form an insertion port 15, which corresponds to the second insert 22. There are multiple ribs 12, and their number is roughly equal to the number of second inserts 22. Similarly, the number of insertion ports 15 formed is also roughly equal to the number of second inserts. When the upper cylinder 10 and the lower cylinder 20 are connected, the latch 210 on the first insert 21 engages with the barb 11, and simultaneously, the second insert 22 engages with its corresponding insertion port 15, thereby achieving a secure connection between the upper cylinder 10 and the lower cylinder 20, and also making the connection operation between the upper cylinder 10 and the lower cylinder 20 very convenient. In a further embodiment, as... Figure 2 and Figure 3 As shown, there are three of each of the first insert 21 and the second insert 22, and the first insert 21 and the second insert 22 are arranged alternately.

[0037] Another embodiment of this application, such as Figure 1 , Figures 4 to 6As shown, this application discloses an aromatherapy diffuser, comprising the cylinder connection structure described in the above embodiment, an essential oil bottle 40, a suction tube 41, and an atomizing core 50. An atomizing core seat is provided inside the upper cylinder 10 for mounting the atomizing core 50. An air inlet channel 16 is provided inside the upper cylinder 10, communicating with the atomizing core seat. Specifically, the air inlet channel 16 is connected to an external compressed air source via an air pipe. Compressed gas enters the atomizing core 50 through the atomizing core seat and enters the atomizing core 50 from the air inlet end 53. A first connecting end 501, connected to the suction tube 41 and communicating with the atomizing core seat, is also provided inside the upper cylinder 10. The suction tube 41 is inserted into the first connecting end 501. The essential oil bottle 40 contains essential oil, which enters the atomizing core 50 through the suction tube 41 and the atomizing core seat via compressed gas. Figure 2 and Figure 3 As shown, a second connecting end 502 connected to the essential oil bottle 40 is provided inside the upper cylinder 10. Furthermore, the bottle mouth of the essential oil bottle 40 is a threaded opening, and the second connecting end 502 is also a threaded opening and is threadedly connected to the bottle mouth of the essential oil bottle 40. Figure 2 As can be seen, the lower cylinder 20 has a space to accommodate the essential oil bottle 40, that is, the essential oil bottle 40 is placed inside the lower cylinder 20. Figure 7 As shown, an air inlet plug 161 is also provided to be inserted into the air inlet channel 16. When the aromatherapy device is not in use, such as during transportation, it can effectively seal the air inlet channel 16 and ensure that the essential oil will not leak out of the air inlet channel 16.

[0038] In further embodiments of this application, such as Figures 4 to 6 As shown, the atomizing core 50 has a liquid spray port 51 and a jet spray port 52, and also has a liquid inlet and an air inlet. The atomizing core seat has a liquid inlet end 54 connected to the liquid suction tube 41, an air inlet end 53 connected to the air inlet channel 16, a liquid outlet connected to the liquid inlet of the atomizing core, and an air outlet connected to the air inlet of the atomizing core.

[0039] In a further embodiment of this application, the atomizing core 50 has an air outlet platform 520 and a liquid outlet inclined surface 510. The air outlet 52 is located on the air outlet platform 520, and the liquid outlet 51 is located on the liquid outlet inclined surface 510. The central axis of the liquid outlet forms an angle with the axis of the air outlet. That is, the compressed gas ejected from the air outlet 52 and the liquid ejected from the liquid outlet 51 are not on the same plane, but form an angle between them. Since the compressed gas is ejected from the air outlet 52 and draws the essential oil in the essential oil bottle to the liquid outlet 51 and then ejects it, the high-speed compressed gas ejected from the air outlet atomizes the essential oil. In a preferred embodiment, such as... Figure 4As shown, the jet nozzle axis is perpendicular to the horizontal plane. In various embodiments, the angle formed by the jet nozzle and the liquid injection nozzle can be adjusted, with a preferred angle range of 90 to 170 degrees. In the above embodiments, as... Figure 2 As shown, a cover 30 is also provided to be connected to the upper cylinder 10. A mist outlet 31 is provided on the cover 30. After the atomizing core 50 atomizes the essential oil into fragrance mist in the upper cylinder 10, the fragrance mist escapes out of the aroma diffuser through the mist outlet 31.

[0040] In a further embodiment of this application, reference is made to Figure 7 In order to effectively prevent the essential oil in the aroma diffuser from leaking out of the mist outlet 31, a rubber plug 32 is provided to be inserted into the mist outlet 31, which can effectively seal the mist outlet 31. When the aroma diffuser is not in operation, it ensures that the essential oil will not leak out of the mist outlet 31 during transportation.

[0041] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has been disclosed above with reference to preferred embodiments, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
