Description

Technical Field

[0001] This utility model relates to the field of aroma diffusion technology, specifically to an aroma diffusion device. Background Technology

[0002] Existing aroma diffusers typically feature an air intake channel in the atomizing head. One end of this channel connects to an air pump via a pipe, while the other end connects to the atomizing head, guiding the airflow generated by the air pump into the atomizing head (see patent application number 201420440948.4). The atomizing head is usually fixed to the diffuser's housing. When the essential oil bottle needs to be replaced, it can be unscrewed. To facilitate bottle replacement, the suction tube connector is designed to be rotatable. However, this method is not convenient for bottle replacement. Existing technology lacks aroma diffusers where the essential oil bottle is easily replaceable and the atomizing head is relatively easy to assemble and disassemble compared to the housing. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a diffuser with an atomizing head that is relatively easy to align and install.

[0004] The technical solution used in this utility model is as follows: A diffuser device is provided, comprising a shell, a mounting base, an atomizing head, an air supply pipe, an essential oil bottle, and an air pump.

One end of the air supply pipe is connected to the air pump, and the other end is mounted on the mounting base. The atomizing head is detachably mounted in the mounting groove. The mounting groove has inclined guide walls on both sides, which are inclined towards the mounting groove along the insertion direction of the atomizing head, causing the width of the mounting groove to decrease sequentially along the insertion direction of the atomizing head. The atomizing head has inclined connecting bodies on both sides that can cooperate with the guide walls. The connecting bodies of the atomizing head can cooperate with the guide walls, allowing the atomizing head to slide into the mounting groove. When the atomizing head is installed in the mounting groove, it is connected to the air supply pipe.

[0010] Preferably, the outer shell includes a shell body and a cover body. One end of the cover body is hinged to the shell body, and the other end is connected to the shell body for opening and closing. The cover body can open or close the mounting groove. When the cover body closes the mounting groove, the cover body abuts against the first arc end.

[0011] Preferably, the atomizing head includes an atomizing body and an air inlet pipe. The air inlet pipe protrudes from a first side relative to the atomizing body. The mounting groove includes a first groove and a second groove that are interconnected. The mounting base has a connecting nozzle. The end of the air supply pipe away from the air pump passes through the connecting nozzle and is located in the second groove. A limiting step is provided between the first groove and the second groove.

[0030] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0031] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0032] Please refer to Figures 1 to 12 This utility model provides a diffuser device, including a housing, a mounting base 1, an atomizing head 22, an air supply pipe 32, an essential oil bottle 23, and an air pump 31. The mounting base 1, the atomizing head 22, the air supply pipe 32, the essential oil bottle 23, and the air pump 31 are all located within the cavity of the housing. The housing is openable and closable. The atomizing head 22 and the essential oil bottle 23 are detachably connected. The mounting base 1 has a mounting groove 11 formed by recessing from the first side a to the second side b (see reference). Figure 3One end of the air supply pipe 32 is connected to the air pump 31, and the other end is installed in the mounting groove 11 of the mounting base 1. The atomizing head 22 is detachably installed in the mounting groove 11. The mounting groove 11 has inclined guide walls 112 on both sides (see reference). Figure 3 The guide wall 112 is inclined towards the mounting groove 11 along the insertion direction of the atomizing head 22, meaning that the width is relatively wider near the opening of the mounting groove 11. This makes the width of the mounting groove 11 gradually decrease along the insertion direction of the atomizing head 22, making it easier to insert the atomizing head 22. The atomizing head 22 has inclined connecting bodies 2241 on both sides that can cooperate with the guide wall 112. The connecting bodies 2241 of the atomizing head 22 can cooperate with the guide wall 112, allowing the atomizing head 22 to slide into the mounting groove 11. When the atomizing head 22 is installed in the mounting groove 11, the atomizing head 22 is connected to the air supply pipe 32.

[0033] This invention features inclined guide walls 112 on both sides of the mounting groove 11, and connecting bodies 2241 on both sides of the atomizing head 22 that mate with the guide walls 112. This allows the atomizing head 22 to be inserted into the mounting groove 11 with good guidance. This ensures a good match between the atomizing head 22 and the mounting groove 11, allowing for a better fit. During installation, the atomizing head 22 is more easily aligned with the mounting groove 11, thus achieving precise alignment between the atomizing head 22 and the air delivery pipe 32, and ensuring the stability of the air delivery pipeline.

[0034] refer to Figure 4-6 , Figure 8-11 In a preferred embodiment, the atomizing head 22 includes an air inlet pipe 221, a base 223, and an atomizing body 224. A connector 2241 is disposed on the atomizing body 224, and the base 223 is located below the atomizing body 224. The base 223 is used for detachable connection with the essential oil bottle 21. The mounting groove 11 is at least partially vertically connected. When the atomizing head 22 is installed in the mounting groove 11, the atomizing body 224 is located inside the mounting groove 11, and the base 223 is located outside the mounting groove 11 and below it. The term "below" in this embodiment can be understood as... Figure 8-9 To understand this, the area closer to the essential oil bottle 21 is considered the bottom, and the area closer to the atomizing head 22 is considered the top. In this embodiment, the connecting body 2241 of the atomizing body 224 serves as the guide within the mounting groove 11, while the base 223 provides the limit outside the mounting groove 11, making the installation and positioning of the atomizing head 22 more precise and the installation easier.

[0035] refer to Figure 4-9In a preferred embodiment, the base 223 is misaligned with the atomizing body 224, causing the base 223 to protrude from the atomizing body 224, exposing the limiting surface 2231. The limiting surface 2231 protrudes at least partially from the side of the atomizing body 224, that is, from the connecting body 2241. Referring to the dotted line c, limiting blocks 12 protrude from both sides of the mounting groove 11 along the dotted line c towards both sides of the atomizing body 224. When the atomizing head 22 is installed in the mounting groove 11, with the atomizing body 224 in the mounting groove 11, the base 223 is located below the mounting groove 11, and the limiting surface 2231 is inserted below the limiting block 12. Through the cooperation of the limiting surface 2231 and the limiting block 12, the cooperation between the atomizing head 22 and the mounting groove 11 during installation can be further guaranteed, achieving a better installation effect, ensuring accurate alignment of the atomizing head 22, and avoiding the problem of unstable atomization after installation.

[0036] refer to Figure 4-9 In a preferred embodiment, the air intake pipe 221 is connected to the atomizing body 224. Both the air intake pipe 221 and the base 223 protrude from the atomizing body 224, and at least part of the protrusion direction of the base 223 is the same as the protrusion direction of the air intake pipe 221. Figure 5 In the middle, it protrudes along the direction of the dotted line e. This allows both the air intake pipe 221 and the base 223 to have a certain limiting and guiding function, achieving a better installation effect between the atomizing head 22 and the mounting groove 11.

[0037] refer to Figure 4 and Figure 8 In a preferred embodiment, the atomizing body 224 includes a first arc-shaped end 2242 and a second arc-shaped end 2243, which are connected by a connector 2241. The radius of the first arc-shaped end 2242 is larger than the radius of the second arc-shaped end 2243. When the atomizing head 22 is installed in the mounting groove 11, the first arc-shaped end 2242 is closer to the opening of the mounting groove 11. When the atomizing head 22 is installed, the first arc-shaped end 2242 faces the mounting groove 11 and is inserted into the mounting groove 11.

[0038] refer to Figure 4-6 In a preferred embodiment, the air inlet pipe 221 is located on the second arc end 2243 and protrudes relative to the first side of the atomizing body 224. The first side of the atomizing body 224 refers to the side close to the mounting groove 11. When the atomizing head 22 is installed in the mounting groove 11, the air inlet pipe 221 is inserted into the air supply pipe 32 fixed on the mounting base. This ensures that the atomizing head 22 is accurately aligned and avoids problems with unstable atomization after installation.

[0039] refer to Figure 1In a preferred embodiment, the outer shell includes a shell body 41 and a cover 42. One end of the cover 42 is hinged to the shell body 41, and the other end is closable connected to the shell body 41. The cover 42 can open or close the mounting groove 11. When the cover 42 closes the mounting groove 11, the cover 42 abuts against the first arc end 2242. This provides a better limiting effect on the atomizing head 22 installed in the mounting groove 11, preventing the atomizing head 22 from loosening. In this invention, the cover abuts and presses against the first arc end 2242 of the atomizing head 22, resulting in better gas delivery stability and a better aroma diffusion effect for the entire diffuser.

[0040] refer to Figure 4-6 In a preferred embodiment, the air inlet pipe 221 protrudes from the first side of the atomizing body 224. When the atomizing head 22 and the mounting groove 11 are installed, the air inlet pipe 221 is inserted into the mounting groove 11 to ensure the connection of the air supply channel.

[0041] refer to Figure 2 and Figure 11-12 In a preferred embodiment, the mounting groove 11 includes a first groove 113 and a second groove 114 that are interconnected. The mounting base 1 has a connecting nozzle 111 that connects to the second groove 114. The end of the air supply pipe 32 away from the air pump 31 passes through the connecting nozzle 111 and is located in the second groove 114. A limiting step 115 is provided between the first groove 113 and the second groove 114. When the atomizing head 22 is installed in the mounting groove 11, the atomizing body 224 is at least partially limited by the limiting step 115 and located in the first groove 113. The air inlet pipe 221 extends into the second groove 114 and is inserted into the air supply pipe 32 located in the second groove 114. In this embodiment, the guiding cooperation between the atomizing head 22 and the mounting groove 11 enables the atomizing head 22 to be easily inserted into the mounting groove 11, and the air inlet pipe 221 is directly inserted into the air supply pipe 32, which can better ensure the stability of the air supply channel and the air supply stability of the aroma diffuser.

[0042] refer to Figure 7-11 In a preferred embodiment, the first groove 113 extends vertically, and there are limiting blocks 12 on both sides of the first groove 113. The atomizing head 22 and the mounting groove 11 cooperate during installation by limiting the limiting surface and the limiting blocks 12 to achieve the limiting cooperation between the atomizing head 22 and the mounting groove 11. This ensures that the atomizing head 22 is accurately aligned during installation and avoids the problem of unstable atomization after installation.

[0043] refer to Figure 12In a preferred embodiment, the second groove 114 has a lower bottom wall, and the air supply pipe 32 located inside the second groove 114 abuts against the lower bottom wall. In this embodiment, the second groove 114 is mainly used to limit the air supply pipe 32. The air supply pipe 32 is located inside the second groove 114, and the opening of the air supply pipe 32 is located inside the second groove 114. When the atomizing head 22 is inserted into the mounting slot 11, the air inlet pipe 221 is directly inserted into the air supply pipe 32 located in the second mounting slot 11, ensuring the convenience and stability of the entire installation.

[0044] refer to Figure 1 , Figure 3 and Figure 10 In a preferred embodiment, the mounting base 1 includes an adjacent first mounting portion and a second mounting portion. The first mounting portion is recessed from the first side a of the mounting base to the second side b of the mounting base to form a mounting groove 11. The air pump 31 is mounted on the second side of the second mounting portion and is mounted in the space formed between the second mounting portion and the housing.

[0045] refer to Figure 10 In a preferred embodiment, the essential oil bottle 23 is axially oriented vertically, the air pump 31 is axially oriented horizontally, and the diffuser also includes a power supply system 33, with the air pump 31 suspended above the power supply system 33. This makes the overall structure more compact.

[0046] refer to Figure 7 , Figure 10 and Figure 11 In a preferred embodiment, the air supply pipe 32 is a flexible hose, and at least part of the end of the air supply pipe 32 away from the air pump 31 extends into the mounting groove 11. When the atomizing head 22 is installed in the mounting groove 11, the air inlet pipe 221 of the atomizing head 22 is inserted into the air supply pipe 32 located in the mounting groove 11.

[0047] The end of the gas pipe 32 away from the air pump 31 has an outwardly protruding first retaining ring 3221 and a second retaining ring 3222. The first retaining ring 3221 and the second retaining ring 3222 are spaced apart, and a snap-fit ​​groove is formed between the first retaining ring 3221 and the second retaining ring 3222. The connecting nozzle 111 of the mounting base 1 has a retaining plate 1111. The retaining plate 1111 of the connecting nozzle 111 snaps into the snap-fit ​​groove between the first retaining ring 3221 and the second retaining ring 3222. The first retaining ring 3221 is located in the mounting groove 11. Specifically, the first retaining ring 3221 is located in the second groove 114, and the lower part of the first retaining ring 3221 abuts against the lower bottom wall of the second groove 114, so that the first retaining ring 3221 can be well limited within the second groove 114. The second retaining ring 3222 is located outside the mounting groove 11, so that the gas pipe 32 can be securely installed on the mounting base 1. When the atomizing head 22 is installed in the mounting slot 11, the air inlet pipe 221 is inserted into the air delivery pipe 32 through the opening of the air delivery pipe 32 located in the second slot 114, and passes through the retaining plate 1111 of the connecting nozzle 111, so that the retaining groove surrounds the outside of the air inlet pipe 221. When the air inlet pipe 221 is inserted into the air delivery pipe 32, the air inlet pipe 221 squeezes the air delivery pipe 32 from the inside to the outside, which squeezes the retaining groove surrounding the air inlet pipe 221, and further squeezes the retaining plate 1111 surrounding the retaining groove, so that the connection between the air inlet pipe 221, the air delivery pipe 32 and the mounting base 1 is tighter, which prevents the air delivery pipe 32 from detaching due to excessive air pressure delivered by the air pump 31 and avoids air leakage.

[0048] In this invention, the cooperation of two retaining rings and a retaining plate 1111 ensures that the air supply pipe 32 is well fixed on the mounting base 1, preventing the air supply pipe 32 from detaching due to excessive air pressure from the air pump 31 and avoiding air leakage. Furthermore, the mounting groove 11 has inclined guide walls 112 on both sides, and the atomizing head 22 has connecting bodies on both sides that can cooperate with the guide walls 112, allowing the atomizing head 22 to be inserted into the mounting groove 11 with good guidance, and ensuring that the air inlet pipe 221 of the atomizing head 22 can be accurately inserted into the air supply pipe 32.
