Description

Technical Field

[0001] This utility model belongs to the field of fragrance machine technology, specifically an atomizing device and a column fragrance machine. Background Technology

[0002] Atomizing devices and column fragrance diffusers are vertical or floor-standing fragrance diffusion devices typically used for scenting large spaces in commercial or residential environments, such as hotel lobbies, shopping malls, and offices. Their core function is to evenly diffuse essential oils into the air using atomization technology, improving the odor of the environment and enhancing the quality of the space.

[0003] Current fragrance diffuser technology uses an air pump to deliver high-speed gas to the atomizing head outlet, creating a negative pressure environment. This negative pressure effectively draws the essential oil liquid from the bottle, and the atomizing head then precisely processes it, transforming the essential oil into tiny atomized particles. These atomized essential oil particles are then ejected outwards with the airflow, allowing the fragrance oil to diffuse evenly throughout the target space, creating a pleasant aroma.

[0004] While the essential oils produced by the above methods can be atomized and diffused into the air, the size of the atomized oil particles is often inconsistent. Larger oil particles, due to their greater weight, tend to settle quickly in the air and cannot diffuse to a greater distance with the airflow. At the same time, larger oil particles also accelerate the waste of essential oils and increase the cost of use.

[0005] Therefore, this application aims to solve the problem of uneven essential oil particles in fragrance diffusers, which prevent them from spreading to a wider area and also increase the waste of essential oils. Utility Model Content

[0006] The purpose of this application is to provide an atomizing device and a column aroma diffuser, which aims to improve the uniformity of essential oil particles in the aroma diffuser, enabling the atomized essential oil to diffuse to a farther area, while saving essential oil usage.

[0007] To achieve the above objectives, this application provides an atomizing device, comprising:

[0008] Atomizing components, including:

[0009] liquid storage bottle;

[0010] An atomizing shell with a cavity is connected to the mouth of the liquid storage bottle. The atomizing shell has two fluid passages, which are respectively connected to the outside and the cavity, the liquid storage bottle and the cavity. The two fluid passages are axially perpendicular to one end of the cavity of the atomizing shell.

[0011] A labyrinth connector is attached to the side of the atomizing shell away from the liquid storage bottle, and has an air inlet that communicates with and extends toward the cavity of the atomizing shell.

[0012] A pump assembly, the output of which is connected to a fluid passage located outside the atomizing housing.

[0013] Furthermore, the two fluid passages of the atomizing shell include:

[0014] A suction tube is connected to the atomizing shell, with its two ends respectively connected to the storage bottle and the cavity of the atomizing shell;

[0015] An air outlet chamber is formed on the atomizing shell, with one end connected to the cavity of the atomizing shell and the other end connected to the outside.

[0016] Furthermore, it also includes an atomizing head, which is connected to one end of the cavity of the atomizing shell in the two fluid passages. The atomizing head has two air channels arranged perpendicularly to each other, and the air channel connected to the atomizing head and the air outlet faces the labyrinth connector.

[0017] Furthermore, the air inlet is located around the atomizing head, and its end face extends between the atomizing head and the liquid storage bottle.

[0018] Furthermore, the atomizing shell has a recycling hole on the side facing the mouth of the liquid storage bottle, and the recycling hole is inclined around its periphery.

[0019] Furthermore, an air outlet cover is connected to the side of the labyrinth connector away from the cavity of the atomizing shell, and a flow guide cavity is formed between the air outlet cover and the labyrinth connector. A through hole is provided at the air inlet to connect to the cavity of the atomizing shell.

[0020] This application also discloses a column-type fragrance diffuser, including a main body, wherein the main body is equipped with the aforementioned atomizing device, and the main body includes:

[0021] shell;

[0022] An inner shell, connected to the inner wall of the outer shell, includes:

[0023] The upper shell, located at one end of the inner shell, has a liquid storage compartment that is open at one end;

[0024] The lower housing, located at the end of the inner housing away from the upper housing, has an energy storage compartment that is open at one end;

[0025] An air outlet is located at the same end of the upper housing and the outer housing, and communicates with the cavity of the atomizing shell.

[0026] Furthermore, the outlet end of the pump assembly is connected to an air pipe, and the other end of the air pipe is provided with a second air inlet connected to the upper housing. The outer wall of the atomizing shell is provided with a first air inlet that is detachably connected to the second air inlet.

[0027] Furthermore, at least one stiffener is provided on one side of the upper housing, and the air pipe is embedded in the end of the stiffener.

[0028] Furthermore, the upper shell and the lower shell are integrally formed, and their cross-sections are polygonal.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] This invention optimizes the atomizing component. One fluid passage ejects high-speed gas, which drives another fluid passage to generate negative pressure, making the essential oil liquid more evenly atomized into tiny particles and prolonging its suspension time in the air. At the same time, the cavity of the atomizing shell and the labyrinth connector form a unique airflow channel. Tiny particles enter from the air inlet of the labyrinth connector and are further refined into essential oil particles after passing through multiple stages of turbulence, ensuring that the fragrance evenly covers a wider space, while ensuring that large essential oil particles settle at the bottom of the atomizing shell, reducing waste.

[0031] The atomizing head features a negative pressure design, which allows gas to fill the cavity of the atomizing shell. This ensures that the essential oil at the bottom of the atomizing shell can flow into the storage bottle through the recovery hole. At the same time, it can also increase the air pressure in the storage bottle, promoting the flow of essential oil from the suction tube to the atomizing head, forming a closed loop and maximizing the utilization rate of the essential oil.

[0032] The unique design of this column-mounted fragrance diffuser divides the inner shell into an upper shell and a lower shell. The upper and lower shells are respectively provided with independent spaces for storing the atomizing components and the energy storage components, which effectively isolates interference between components, improves overall operational stability, and ensures a compact internal structure, making it easy to maintain and replace components.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please refer to the details. Figure 5 , Figure 6 and Figure 7As shown, an atomizing device includes an atomizing component 51 and a pump assembly 7. The atomizing component 51 includes a liquid storage bottle 54, an atomizing shell 511 with a cavity, and a labyrinth connector 512. The atomizing shell 511 is connected to the mouth of the liquid storage bottle 54. The atomizing shell 511 has two fluid passages, which are respectively connected to the outside and the cavity, and the liquid storage bottle 54 and the cavity. The two fluid passages are axially perpendicular at one end of the cavity of the atomizing shell 511. The axial perpendicularity is such that the air outlet directions of the two fluid passages are perpendicular to each other. The labyrinth connector 512 is connected to the side of the atomizing shell 511 away from the liquid storage bottle 54, and has an air inlet that is connected to and extends toward the cavity of the atomizing shell 511. The pump assembly 7 is connected to the fluid passage located on the outside of the atomizing shell 511 and pumps in gas. By pumping gas into the atomizing component 51 through the pump assembly 7, the atomizing component 51 can spray essential oil droplets, thereby completing the atomization operation.

[0044] like Figure 6 and Figure 7 As shown, specifically, the liquid storage bottle 54 stores a liquid containing essential oils, such as a mixture of water and essential oils. The atomizing shell 511 has two internal fluid passages, which are divided into a first fluid passage and a second fluid passage. The two ends of the first fluid passage are connected to the outside of the atomizing shell 511 and its cavity, respectively, i.e., connected to the pump assembly 7 of this application, causing the pump assembly 7 to pump gas into the cavity of the atomizing shell 511. The second fluid passage connects the liquid storage bottle 54 and the cavity of the atomizing shell 511. The first fluid passage ejects high-speed gas into the cavity of the atomizing shell 511, creating a negative pressure area at the port of the second fluid passage, causing the second fluid passage to pump the liquid storage bottle... The mixture of water and essential oil in bottle 54 is drawn outwards. The second fluid passage forms small particles of essential oil in the cavity of atomizing shell 511. If the drawn-out essential oil collides with high-speed gas, this application preferably uses atomizing head 516 to atomize the adsorbed essential oil into small particles of essential oil. When large and small particles of essential oil are formed in the cavity of atomizing shell 511, the labyrinth connector 512 has a downward-extending air inlet, which causes the large particles of essential oil to fall to the bottom of the cavity of atomizing shell 511, while the small particles of essential oil can flow from the air inlet to the labyrinth connector 512 under the action of air, thereby filtering the large particles of essential oil and spraying the small particles of essential oil from the air inlet, improving the overall atomization effect.

[0045] like Figure 5 and Figure 6 As shown, both the first and second fluid passages can be connected to the corresponding positions of the atomizing shell 511 via pipes, ensuring the stability and sealing of fluid transmission while facilitating maintenance and replacement. In this application, both the first and second fluid passages are integrally molded with the atomizing shell 511, ensuring a compact structure, eliminating leakage risk, and improving overall service life.

[0046] Specifically, the atomizing shell 511 has two fluid passages, including a suction tube 514 and an outlet chamber 513. The suction tube 514 is connected to the atomizing shell 511, with its two ends connected to the storage bottle 54 and the cavity of the atomizing shell 511, respectively. The outlet chamber 513 is located on the atomizing shell 511, with one end connected to the cavity of the atomizing shell 511 and the other end connected to the outside, facilitating the pump assembly 7 to pump gas into the outlet chamber 513. The suction tube 514 is inserted and fixed to the bottom of the atomizing shell 511, with its other end flowing out through the water nozzle at the bottom of the atomizing shell 511. The suction tube 514 is made of corrosion-resistant material to ensure that it will not be damaged by long-term contact with essential oil liquid.

[0047] like Figure 6 As shown, this application preferably uses an atomizing head 516 to atomize essential oil into small water vapor particles. The atomizing head 516 is connected to one end of the cavity of the atomizing shell 511, which has two air channels arranged perpendicularly to each other. The air channel of the atomizing head 516 connected to the air outlet 513 faces the labyrinth connector 512, that is, the atomizing head 516 is connected to the first fluid channel and the connection direction is upward, facing the labyrinth connector 512. The air channel of the atomizing head 516 connected to the second fluid channel is arranged horizontally. The essential oil passing through the atomizing head 516 forms a fine mist, which is propelled by the high-speed gas ejected from the first fluid channel and quickly diffuses into the cavity of the atomizing shell 511. The mist collides with the labyrinth connector 512 and is refined. The refined mist is effectively filtered through the air inlet of the labyrinth connector 512, and small particles of essential oil are smoothly ejected, while large particles settle to the bottom, ensuring uniform and efficient atomization.

[0048] like Figure 6 As shown, the air intake is located on the periphery of the atomizing head 516, and its end face extends between the atomizing head 516 and the liquid storage bottle 54. This allows the essential oil sprayed from the atomizing head 516 to form a finer mist under the impact of the gas, evenly covering the entire cavity and improving the utilization rate of the essential oil. At the same time, after the essential oil is atomized, it settles into the air intake and can then pass through the small channels of the labyrinth connector 512 to further separate large particles, ensuring that only fine mist enters the usage area and achieves efficient atomization.

[0049] like Figure 5 and Figure 6As shown, to improve the recovery effect of essential oils, a recovery hole 515 is provided on the side of the atomizing shell 511 facing the bottle opening 54. The recovery hole 515 is inclined around its periphery. After large particles of essential oil collide with the inner wall of the atomizing shell 511, they gradually settle at the bottom of the cavity of the atomizing shell 511 and flow into the bottle 54 through the inclined surface around the recovery hole 515. Since the cavity of the atomizing shell 511 is filled with gas, the flow of essential oil in the cavity of the atomizing shell 511 into the bottle 54 is further improved. At the same time, gas is injected into the bottle 54 from the recovery hole 515, forming a micro-pressure environment, which promotes the adsorption of essential oil in the bottle 54 by the suction tube 514. The design of the recovery hole 515 not only optimizes the utilization rate of essential oils but also reduces waste, ensuring that essential oils are used efficiently every time.

[0050] like Figure 5 and Figure 7 As shown, the labyrinth connector 512 is connected to an air outlet cover 52 on the side of the cavity away from the atomizing shell 511. A guide cavity 5122 is formed between the air outlet cover 52 and the labyrinth connector 512. A through hole 5123 is provided at the air inlet to connect to the cavity of the atomizing shell 511. The labyrinth connector 512 is provided with a fixing post 5121, which is fixed to the bottom of the atomizing shell 511 with bolts. The gas in the cavity of the atomizing shell 511 enters the guide cavity 5122 through the through hole 5123, forming a directional airflow, which pushes the fine mist to be sprayed out evenly. At the same time, the bottom of the guide cavity 5122 is inclined, so that the settled large particles of essential oil flow back to the cavity of the atomizing shell 511 along the inclined surface for further recycling, ensuring that the atomization process is efficient and residue-free. The through hole 5123 is preferably honeycomb structure to improve the flow of fine particles of essential oil and hinder the flow of large particles of essential oil.

[0051] like Figure 1 and Figure 2 As shown, a column-type aroma diffuser includes a main body 2, on which the aforementioned atomizing device is installed. The main body 2 includes an outer shell 23 and an inner shell 24. The inner shell 24 is connected to the inner wall of the outer shell 23 and includes an upper shell 241, a lower shell 243, and an air outlet 3. The upper shell 241 is located at one end of the inner shell 24 and has a liquid storage chamber 242 that is open at one end. The lower shell 243 is located at the end of the inner shell 24 away from the upper shell 241 and has an energy storage chamber 244 that is open at one end. The air outlet 3 is located at the same end of the upper shell 241 and the outer shell 23 and communicates with the cavity of the atomizing shell 511. The outer shell 23 can be open on one side, which allows the inner shell 24 to be fixed from one side of the outer shell 23 by a snap or thread, ensuring structural stability.

[0052] like Figure 2 and Figure 3As shown, specifically, the outer casing 23 of this application includes a front cover 21, an outer casing 23, and a rear cover 25. The rear cover 25 and the front cover 21 are respectively connected to the outer casing 23 by snaps or bolts. The outer casing 23 is square or rectangular in shape, which is convenient for installation and disassembly. The front cover 21, the outer casing 23, and the rear cover 25 are all made of environmentally friendly materials and are integrally injection molded by mold. The rear cover 25 is divided into two independent lower covers 251 and upper covers 252. The lower cover 251 is directly snapped or bolted to the inner casing 24 and the lower casing 243, so that the lower cover 251 covers the energy storage chamber 244 of the inner casing 24. The upper cover 252 is detachably connected to the upper casing 241 and covers the liquid storage chamber 242 of the upper casing 241. The liquid storage chamber 242 contains the atomizing component 51, which is convenient for users to check and add essential oil at any time. At the same time, the upper cover 252 is provided with a vent hole to ensure the internal gas circulation, maintain the stable operation of the fragrance diffuser, and also facilitate the observation of the amount of essential oil in the liquid storage bottle 54.

[0053] In the above design, the liquid storage chamber 242 is an independent space horizontally enclosing three sides of the atomizing component 51. The atomizing component 51 can only be moved into the liquid storage chamber 242 horizontally from the top cover 252. The energy storage component 6 is preferably a battery, which can provide long-lasting power to the entire fragrance diffuser and ensure stable operation over a long period of time. The energy storage chamber 244 is designed to be concealed within the lower housing 243, which does not affect the overall aesthetics and is easy to replace, thus improving the user experience.

[0054] like Figure 3 and Figure 4 As shown, the pump assembly 7 is mounted on the lower housing 243. The air outlet of the pump assembly 7 is connected to an air pipe 71. The other end of the air pipe 71 is provided with a second air inlet 72 connected to the upper housing 241. The outer wall of the atomizing shell 511 is provided with a first air inlet 53 that is detachably connected to the second air inlet 72. The second air inlet 72 is fixed to the upper housing 241. The outer wall of the atomizing shell 511 is provided with a handle for easy gripping. The atomizing shell 511 is tightly threaded to the liquid storage bottle 54. When the liquid storage bottle 54 needs to be replaced, by grasping the handle, the atomizing shell 511 can be moved towards the liquid storage chamber 242, so that the first air inlet 53 on the outer wall of the atomizing shell 511 and the second air inlet 72 are engaged and fixed, thus completing the quick replacement of the liquid storage bottle 54 and completing the connection between the pump assembly 7 and the atomizing shell 511, ensuring simple and efficient operation.

[0055] To further improve the stability of the trachea 71, at least one stiffener 246 is provided on one side of the upper shell 241. The trachea 71 is embedded in the end of the stiffener 246. Along the height direction of the upper shell 241, the ends of multiple stiffeners 246 are provided with arc-shaped, square, or C-shaped slots. When the front cover 21 is fixed to the inner shell 24, the trachea 71 is directly confined between the stiffener 246 and the front cover 21. At the same time, the stiffener 246 can also enhance the structural strength between the upper shell 241 and the outer shell 23. The design of the stiffener 246 not only improves the stability of the overall structure, but also prevents the trachea 71 from shifting during use, ensuring unobstructed airflow.

[0056] like Figure 4 As shown, the upper shell 241 and the lower shell 243 are integrally formed and have a broken cross-section. That is, the upper shell 241 protrudes to the left to form a liquid storage chamber 242 for accommodating the atomizing component 51. The lower end of the upper shell 241 is fixed to the lower shell 243, and the lower shell 243 also protrudes to the left to form an energy storage chamber 244 for accommodating the energy storage component 6. The two are tightly connected. At the same time, the pump assembly 7 is installed at the relative position of the lower shell 243 and the energy storage component 6, which facilitates the pump assembly 7 to directly absorb the energy provided by the energy storage component 6, ensuring a compact structure and high space utilization. In addition to the above, the bottom wall and top wall of the liquid storage chamber 242 are preferably horizontal, but can also be inclined. Different broken cross-sections can be selected as needed.

[0057] like Figures 2 to 4 As shown, a sound chamber 245 is also provided below the pump assembly 7. The sound chamber 245 has a built-in speaker and audio module, which can play music via Bluetooth. The sound chamber 245 is cleverly designed so as not to affect the fragrance function, while providing an immersive experience. The sound chamber 245 is preferably integrally molded with the lower housing 243 to make the overall structure more robust. The front cover 21 is also integrally molded with a sound hole 22, which is correspondingly set with the sound chamber 245 to facilitate the housing of the speaker and audio module.

[0058] like Figure 2 and Figure 3As shown, a base 1 is installed below the column fragrance diffuser. The base 1 is used to improve the stability of the column fragrance diffuser. The base 1 includes a bottom cover 12 fixedly connected to the lower housing 243. A base plate 11 is snapped and threaded around the bottom cover 12. A space is reserved between the base plate 11 and the bottom cover 12 to accommodate the circuit board. A display component 13 is installed on the bottom cover 12. The display component 13 can display the working status of the column fragrance diffuser in real time, such as fragrance concentration and Bluetooth connection status. The bottom of the base plate 11 is provided with an anti-slip pad to ensure that the device is placed stably and that the user can operate it with more peace of mind. The display component 13 can use an OLED, LCD or LED screen, which has a clear display and sensitive touch. The user can adjust the brightness according to their needs. The front cover 21 is also provided with a decorative plate 4. The decorative plate 4 is fixed to the front cover 21 by bolts. The decorative plate 4 and the rib plate 246 together restrict the air tube 71 to prevent it from falling off.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
