Description

Technical Field

[0001] This utility model relates to the field of aroma diffusers, and more specifically, to an aroma diffuser. Background Technology

[0002] Aroma diffusers, common household appliances in modern life, use specific technologies to transform aromatherapy liquids into fine mist, achieving multiple effects such as aromatherapy, humidification, and air purification. Among the many types of aroma diffusers, those that utilize high-pressure gas to create negative pressure to extract, mix, and then atomize the aromatherapy liquid are highly favored due to their efficient and rapid aroma diffusion characteristics. The working principle of this type of aroma diffuser is roughly as follows: high-pressure gas creates negative pressure through a specific device, attracting the aromatherapy liquid into the mixing area. Subsequently, the high-pressure gas and aromatherapy liquid are refined into tiny particles during high-speed mixing, ultimately being diffused in a mist form, creating a pleasant aromatherapy atmosphere.

[0003] However, in practical applications, especially when aroma diffusers are designed with detachable structures (such as replaceable aroma diffuser containers), ensuring the connection and sealing of pipelines during the delivery of high-pressure gas has become a pressing technical challenge. To address this issue, existing technology proposes a design scheme that incorporates a pressure chamber within the aroma diffuser. This scheme places both the aroma diffuser container and the atomizing component within the pressure chamber, thereby greatly simplifying the high-pressure gas pipeline setup, reducing manufacturing difficulty and cost, and also improving the overall compactness and aesthetics of the aroma diffuser.

[0004] While the aforementioned solutions have achieved significant results in simplifying pipe installation, they reveal obvious shortcomings in sealing the atomizing component and the pressure chamber. Currently, most aroma diffusers of this type use a threaded connection with a sealing ring for sealing. However, during the threaded connection process, the atomizing component exerts long-term pressure and friction on the sealing ring, which not only accelerates the wear of the sealing ring but also greatly shortens its lifespan, thus affecting the overall performance and user experience of the aroma diffuser. To overcome the sealing problem caused by the threaded connection, some aroma diffusers have adopted a snap-fit ​​structure to accommodate the sealing ring. However, snap-fit ​​structures, such as clips and slots, require an interference fit to effectively press the sealing component for a seal. Since the atomizing head and body are generally made of plastic, they will deform under the sealing reaction force. To reduce the decrease in sealing performance caused by deformation, the size of the interference fit is increased. However, this results in greater force being needed to overcome the interference fit during use to install and disassemble the atomizing head and body, affecting the user experience.

[0005] In addition, these types of aroma diffusers typically arrange the touch control panel around the atomizing head. This design not only presents a clean and aesthetically pleasing appearance but also allows for a rational layout of the operating area within a limited space, facilitating user adjustments to various functions. The touch control panel needs to be tightly fitted to the surface of the plastic component supporting it on the main body to ensure a good tactile feel and stable electrical connection. However, in actual manufacturing, due to various factors, the surface flatness of the plastic component is difficult to achieve ideal results. During the process of attaching the flexible control circuit to the surface of the plastic component, defects such as warping or air bubbles are easily generated. Warping can cause local gaps between the flexible control circuit and the surface of the plastic component, making signal transmission unstable during touch operation, potentially leading to accidental touches or malfunctions, severely impacting the user experience. Air bubbles not only affect the aesthetics of the aroma diffuser but also further interfere with the electrical connection between the flexible control circuit and the plastic component, reducing the sensitivity and reliability of the touch control panel. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of the prior art and provide a structure for an aromatherapy diffuser that satisfies user experience and overcomes insufficient sealing.

[0007] The technical solution adopted by this utility model is to provide an aromatherapy diffuser, including a main body, an atomizing head, and a container. The atomizing head is connected to the container and is used to extract liquid from the container and mix it with high-pressure gas to form a mist that escapes from the cover. A sealing component is also provided between the atomizing head and the main body to achieve a sealed connection, forming a pressure cavity between the container and the main body. A high-pressure air source is provided to supply high-pressure air to the pressure cavity, and the high-pressure air is supplied to the atomizing head through the pressure cavity. A control panel is provided on the upper surface of the main body, and a through hole is formed on the control panel for the atomizing head and the container to be installed. A control component is also installed inside the main body and connected to the control panel. The improved structure is that the control panel includes a display layer and a metal support layer from top to bottom.

[0008] The control panel is located on the upper surface of the main body, with a through hole for the atomizing head and container to be installed. Therefore, the control panel is ring-shaped, making it prone to deformation during installation, resulting in an uneven surface. To address this, the improved control panel in this design includes a display layer and a metal support layer from top to bottom. The metal support layer prevents deformation of the display layer, ensuring a flat and aesthetically pleasing finish after installation. Furthermore, a sealing assembly achieves a tight seal between the atomizing head and the main body. The mating structure between the atomizing head and the main body, such as clips and slots, requires an interference fit to effectively press the sealing assembly for a proper seal. However, since atomizing heads and main bodies are typically made of plastic, they deform under the sealing reaction force. To reduce the decrease in sealing performance caused by deformation, the interference fit size is increased. However, this results in greater force being required to overcome the interference fit during installation and disassembly of the atomizing head and main body, impacting the user experience. The aforementioned metal support layer can solve this technical problem. With the addition of the metal support layer, the metal support layer has higher resistance to deformation and can prevent plastic parts from deforming. This eliminates the need for interference fit and achieves the desired sealing effect, resulting in a better user experience during disassembly and assembly.

[0009] To improve sealing performance, the atomizing head and the main body are engaged by 2-5 circumferentially distributed fastening structures. The fastening structure includes a circumferentially protruding fastening element of the atomizing head and a circumferentially concave fastening groove of the main body. The control panel also includes a bracket disposed below the metal support layer, and the fastening groove is disposed inside the bracket.

[0010] To achieve a reliable seal between the atomizing head and the main body, this design employs a circumferentially distributed array of 2-5 interlocking structures in conjunction with the sealing component, preferably 3-5 interlocking structures. The purpose of at least three interlocking structures is to form a stable pressing plane, while the purpose of no more than five is to reduce structural complexity and facilitate interlocking. During the mating process, the atomizing head and the main body jointly press the sealing component downwards. The interlocking component of the atomizing head is first vertically inserted into the vertical part of the interlocking groove, and then the atomizing head is rotated so that the interlocking component enters laterally into the horizontal part of the interlocking groove. The horizontal part provides good interlocking support, thereby achieving a stable connection between the atomizing head and the main body and ensuring the sealing of the pressure cavity. Because the interlocking structure does not exert excessive pressure or friction on the sealing component during mating, this design effectively extends the service life of the sealing component. Furthermore, the interlocking groove is located inside the bracket, and the bracket and the display layer are isolated by a metal support layer. This effectively prevents deformation of the bracket under stress from being transmitted to the display layer, ensuring the flatness of the display layer during use.

[0011] Further design optimization involves fixing the metal support layer to the bracket using fasteners. These fasteners are arranged around the through-hole and positioned at the locations where the corresponding fasteners and slots engage. This structure utilizes fasteners to enhance the stability of the engagement between the fasteners and slots. By positioning them at the corresponding engagement locations, the fasteners prevent one or more slots from deforming upwards due to reaction forces during engagement. Even after multiple disassemblies and reassemblies, a stable pressing plane can be formed between the atomizing head and the main body to seal the component. The fasteners typically use screws that engage with screw holes on the bracket, with the screw holes located circumferentially outside the engagement locations of the fasteners and slots.

[0012] The locking groove is L-shaped, with a vertical section for vertical insertion of the locking component and a horizontal section for horizontal insertion of the locking component. During mating, the atomizing head and the main body compress and seal the assembly to achieve a seal. The horizontal section does not need to be perfectly horizontal. To increase the pressure on the sealing assembly, it can be designed to be slightly inclined downwards at a certain angle, or inclined at a certain angle and then extended into a horizontal section, which provides higher mating stability.

[0013] Based on the aforementioned interlocking structure, a transition slope or transition arc surface is added between the vertical and horizontal sections. If necessary, the interlocking component can also be chamfered. This provides a smoother transition path as the interlocking component rotates from the vertical section into the horizontal section, reducing frictional resistance between the interlocking component and the interlocking groove, resulting in a smoother interlocking process. Simultaneously, the distance between the atomizing head and the main body is further reduced, further compressing the sealing assembly and improving sealing performance.

[0014] For a rational structural layout, the main body includes an inner cavity and an outer shell. The inner cavity is located within the outer shell, and the container is placed within the inner cavity. A sealing assembly is positioned at the upper port edge of the inner cavity to form a seal between it and the atomizing head. A pressure chamber is formed between the container and the inner cavity. The inner cavity is connected to the lower side of the support, and the two can be fixed together by the aforementioned fasteners. The support and the upper port edge of the inner cavity jointly fix the sealing assembly. A high-pressure air source is located between the inner cavity and the outer shell and is connected to the pressure chamber via an air supply pipe. By designing the inner cavity and outer shell in layers and rationally arranging the container, sealing assembly, pressure chamber, and high-pressure air source, the entire device structure becomes more compact and efficient. Furthermore, this structure allows the support, inner cavity, high-pressure air source, and other internal structures and control panels to be integrated as a single component, assembled separately, and then embedded into the outer shell as a whole.

[0015] The aforementioned integrated components and housing can have the following two embedded installation structures:

[0016] Firstly, a supporting step is provided at the upper edge of the outer shell, and the edge of the bracket is supported on the supporting step. The inner cavity is supported inside the outer shell by the bracket. This structure suspends the inner cavity and components such as the high-pressure air source at the edge of the shell through the bracket. The control panel is supported on the bracket, and the atomizing head and container are supported inside. This requires high strength from the bracket.

[0017] Secondly, a supporting step is provided at the upper edge of the outer shell, and a supporting structure extends from the upper part of the inner cavity towards the outer shell. The supporting structure has an outwardly extending flange, which is supported on the supporting step. The inner cavity is supported inside the outer shell by the flange. This structure uses a supporting structure extending from the inner cavity to support the outer shell, and then a bracket and control panel are stacked on the supporting structure. The bracket supports the atomizing head and the container, which requires less strength from the bracket.

[0018] Furthermore, a transition chamber is provided between the air supply pipe and the pressure chamber. High-pressure air enters the pressure chamber after passing through the transition chamber from the air supply pipe. The transition chamber buffers the flow rate of the high-pressure air, making its pressure distribution more uniform, thereby improving the pressure stability within the pressure chamber. It also effectively absorbs and disperses the noise generated by the high-pressure air, reducing the operating noise of the equipment, preventing aromatherapy liquid from entering the high-pressure air source, and enhancing the user experience.

[0019] Specifically, the transition chamber surrounds the inner cavity, has an air inlet connected to the air supply pipe, and multiple air outlets communicating with the inner cavity. The surrounding design of the transition chamber provides better structural support and enhances overall stability. The multiple air outlets allow for a more even distribution of high-pressure air within the inner cavity. These multiple air outlets are slit-shaped, extending vertically downwards from the upper end of the inner cavity, with their lower ends maintaining a certain distance from the bottom of the transition chamber. The slit-shaped air outlets increase the size of the outlets, preventing excessively high or low local pressures, and avoiding the decrease in sidewall strength caused by overly large openings, thus ensuring structural performance. The slit-shaped air outlets maintaining a certain distance from the bottom of the transition chamber create a cavity at the bottom, allowing the atomized aromatherapy liquid to condense and remain within the transition chamber when it occasionally enters.

[0020] Furthermore, the inner cavity, supporting structure, and transition air chamber are integrally molded. This one-piece injection molding structure not only reduces the number of components, simplifies assembly, and improves production efficiency, but also ensures the overall strength of the supporting structure.

[0021] Adding a metal support layer improves the overall user experience and lifespan of the aroma diffuser, while also increasing the yield rate in production. The sealing assembly features a completely new design, significantly improving the sealing performance of the inner cavity. The connecting ring surface serves as a reference for installation and positioning, simplifying the assembly process. Simultaneously, the design of the pressing ring surface allows the sealing assembly to be pressed and fixed by other internal structures while being installed on the upper edge of the inner cavity, preventing displacement during repeated pressing. The control panel, from top to bottom, includes a display layer and a metal support layer. The metal support layer prevents deformation of the display layer, resulting in a flat and aesthetically pleasing finish after installation. Furthermore, the bracket design not only supports the control panel but also, together with the inner cavity, fixes the pressing ring surface of the sealing assembly, further enhancing structural stability and sealing performance.

[0052] like Figure 2 and Figure 5 As shown, the atomizing head 200 and the main body 100 are engaged by three circumferentially distributed fastening structures 700. Each fastening structure 700 includes a circumferentially protruding fastening element 710 on the atomizing head 200 and a circumferentially concave fastening groove 720 on the inner circumference of the main body 100. Figure 6As shown, the inner circumferentially concave fastening groove 720 of the main body 100 is generally L-shaped. The fastening groove 720 has a vertical part 721 for the fastening member 710 to be inserted vertically and a horizontal part 722 for the fastening member 710 to be inserted horizontally. A transition slope 723 is provided between the vertical part 721 and the horizontal part 722. When engaged, the atomizing head 200 and the main body 100 squeeze the sealing assembly 600 to achieve a seal.

[0053] like Figure 7 and Figure 8 As shown, a control panel 110 is provided on the upper surface of the main body 100.

A transition air chamber 410 is also provided between air supply pipe 510 and pressure cavity 400. High-pressure air enters transition air chamber 410 from air supply pipe 510 and then enters pressure cavity 400. Combined with... Figure 14 As shown, the transition air chamber 410 is formed around the inner cavity 130. It is provided with an air inlet 411 connected to the air supply pipe 510, and multiple air outlets 412 connected to the inner cavity 130. The air outlets 412 are slit-shaped and extend vertically downward from the upper port of the inner cavity 130, with their lower ends maintaining a certain distance from the bottom of the transition air chamber 410.

[0055] like Figure 15 and Figure 13As shown, the sealing assembly 600 includes an outer sealing ring 610 sleeved on the outer side of the upper port edge of the inner cavity 130 and an inner sealing ring 620 embedded in the inner side of the upper port edge of the inner cavity 130. The height of the outer sealing ring 610 is greater than that of the inner sealing ring 620. The upper end faces of the outer sealing ring 610 and the inner sealing ring 620 are connected into a whole by a connecting ring surface 630. A transition arc surface 631 is provided on the connecting ring surface 630 at the transition part to the inner sealing ring 620. The connecting ring surface 630 extends outward beyond the outer sealing ring 610 to form a pressing ring surface 640.

The high-pressure air source 500 is disposed between the inner cavity 130 and the outer shell 140. There is no transition air chamber 410 between the air supply pipe 510 and the pressure cavity 400. The air supply pipe 510 is directly connected to the pressure cavity 400 through the air outlet 412.

[0060] like Figure 22As shown, the difference lies in that this embodiment also provides a sealing assembly 600 with another structure. The sealing assembly 600 includes an outer sealing ring 610 sleeved on the outer side of the upper port edge of the inner cavity 130 and an inner sealing ring 620 embedded in the inner side of the upper port edge of the inner cavity 130.
