A type of aroma diffuser

Abstract

This utility model discloses a misting aromatherapy diffuser, including an air duct control component. The air duct control component includes a housing, an output channel, and a moving part. The moving part rotates within the housing. The output channel is located on the side of the housing and communicates with the housing. A fan is connected to the other side of the housing. The housing has a first air outlet at a position corresponding to the output channel. The moving part rotates to open or close the first air outlet. By setting the air duct control component as a rotating moving part, the rotation of the moving part opens or closes the first air outlet, thus switching the air duct. Compared with the previous method of linear motion driven by a screw, this greatly shortens the stroke of the moving part, improves the efficiency of air duct switching, and makes the switching process more direct and faster. At the same time, due to the shortened stroke and simpler movement, the structural failure rate is lower.

Description

Technical Field

[0001] This utility model relates to the field of aromatherapy equipment, and in particular to an atomizing aromatherapy machine. Background Technology

[0002] Aroma diffusers are common fragrance dispersing devices. They work by atomizing essential oils into aromatherapy smoke, which is then expelled by airflow.

[0003] The smoke extraction principle of an atomizing aroma diffuser is to first expel the smoke generated inside the atomizer into the visible cavity, and then expel the smoke accumulated in the visible cavity to the outside of the product. These two smoke extraction processes require different air ducts, hence the existence of two independent fans responsible for exhausting air from different ducts.

[0004] In the Chinese utility model patent with application number 2024216239647, the original dual fans are transformed into a single fan with a moving part to switch the air ducts by using a duct control component and a linear drive of a screw to achieve exhaust of the two air ducts.

[0005] However, the linear drive method of the screw is less efficient, the linear movement results in a longer stroke for screw rotation, and the speed of closing or opening the air duct is slower. Utility Model Content

[0006] This invention provides a misting aromatherapy diffuser, which aims to solve the problem of low efficiency in the screw linear drive method of the air duct control component of existing aromatherapy devices.

[0007] According to an embodiment of this application, a misting aroma diffuser is provided, including an air duct control component. The air duct control component includes a housing, an output channel, and a moving component. The moving component rotates within the housing. The output channel is located on the side of the housing and communicates with the housing. A fan is connected to the other side of the housing. The housing has a first air outlet at a position corresponding to the output channel. The moving component rotates to open or close the first air outlet.

[0008] Preferably, the inner surface of the receiving shell is a cylindrical structure, and the moving part is in contact with the inner surface of the receiving shell.

[0009] Preferably, the inner wall of the receiving shell is provided with a limiting block, which is located at both ends of the moving part in the direction of rotation.

[0010] Preferably, the moving member has an outwardly protruding arc surface on the surface corresponding to the limiting block, and the limiting block has a concave arc surface on the side corresponding to the moving member, with the moving member inserted into the side of the limiting block.

[0011] Preferably, the outer surface of the receiving shell is further connected to a power component, which is connected to the moving component and drives the moving component to rotate.

[0012] Preferably, one end of the power component is provided with a first gear, and the moving component meshes with the first gear at the end exposed outside the housing.

[0013] Preferably, the power component is located on the top of the outer side of the housing, and the output channel and the fan are respectively located on opposite sides of the housing.

[0014] Preferably, a second air outlet is provided on the housing, and the second air outlet is located on the top of the housing; the second air outlet is located outside the moving area of ​​the moving part.

[0015] Preferably, the moving part includes an engaging part, a sealing part, and a connecting part arranged in sequence. The engaging part is exposed on the outside of the housing. The sealing part is used to rotate to close or open the first air outlet. The connecting part passes through the side wall of the housing and is rotatably connected to the housing.

[0016] Preferably, the sealing portion is an arc-shaped plate.

[0017] Compared with the prior art, the atomizing aroma diffuser provided by this utility model has the following beneficial effects:

[0018] 1. By setting the air duct control component as a rotating moving part, the rotation of the moving part opens or closes the first air outlet, thus switching the air duct. Due to the short rotational stroke, the first air outlet can be opened or closed quickly. Compared with the previous method of linear motion driven by a screw, this greatly shortens the stroke of the moving part, improves the efficiency of air duct switching and opening or closing, and makes the switching process more direct and faster. At the same time, because the stroke is shortened and the movement is simpler, the structural failure rate is lower.

[0019] 2. By designing the inner wall of the housing as a cylindrical structure, the curved inner wall reduces noise from the vertical impact of airflow compared to an internal rectangular structure, resulting in better noise reduction. Simultaneously, the cylindrical inner wall maintains constant contact with the moving parts, improving the airtightness of the moving parts to the first air outlet. Since the fan consistently blows air into the housing, when the moving parts rotate to close the first air outlet, the airflow force on the moving parts further enhances the airtightness between them and the housing.

[0020] 3. By placing the meshing part of the moving parts and the power parts on the outside of the housing, the driving meshing structure is located outside the smoke flow area. Combined with the airtightness of the housing, the meshing transmission parts will not be affected by the adhesion of liquefied aromatherapy oil during long-term use, allowing the meshing transmission to maintain stable operation during long-term use. Users do not need to disassemble and reassemble, which facilitates the long-term use of the product.

[0021] 4. The entire air duct control assembly has a closed structure, which isolates the air duct from the electronic components inside the aromatherapy device, preventing the liquefied smoke from corroding the electronic components inside the device and increasing the product's lifespan.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0038] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0039] Please combine Figure 1 , Figure 2 and Figure 3 The first embodiment of this utility model discloses an atomizing aroma diffuser, including a cover 1, a cartridge assembly 2, and a blower assembly 3. The cover 1 covers one end of the blower assembly 3, and a cavity 100 is formed between the cover 1 and the blower assembly 3 (e.g., Figure 7 (As shown in the diagram). The cartridge assembly 2 passes through the housing 1 and communicates with the blower assembly 3, with the cartridge assembly 2 located at the top of the blower assembly 3.

[0040] It is understood that the casing 1 is made of transparent or semi-transparent material, and the cartridge assembly 2 contains aromatherapy liquid and a heating element. After the heating element heats up, it atomizes the aromatherapy liquid to form smoke. The blower assembly 3 is used to expel the smoke from the cartridge assembly 2. The smoke first accumulates in the cavity area inside the casing 1 and the blower assembly 3, and finally is discharged outside the casing 1. Users can observe the flow and accumulation of smoke inside the casing 1 through the casing 1, forming a cloud-like visual effect and enhancing the aesthetics of the product.

[0041] It is understood that in this embodiment, the cartridge assembly 2 is an atomizer structure in existing atomizing aromatherapy devices, which may specifically include a heating wire, an oil storage tank, oil-absorbing cotton, and internal tubing. The aromatherapy liquid in the oil storage tank comes into contact with the heating wire through the oil-absorbing cotton. The heating wire heats and atomizes the aromatherapy liquid to form aromatherapy smoke, which is discharged to the outside through the internal tubing. Since the cartridge assembly 2 is a conventional component in the atomizing aromatherapy device industry, it will not be described in detail in this embodiment.

[0042] Please continue reading. Figure 3 The blower assembly 3 includes an air duct control assembly, a guide shell 31, and a fan 32 disposed within the guide shell 31. The guide shell 31 covers the base 33, and the guide shell 31 and the base 33 form a space to accommodate the air duct control assembly and the fan 32. The air duct control assembly is connected to the cartridge assembly 2 and the cavity 100. Under the control of the air duct control assembly, the fan 32 discharges the aromatherapy smoke generated in the cartridge assembly 2 into the cavity 100 and discharges the aromatherapy smoke in the cavity 100 to the outside of the product. Specifically, as shown... Figure 2 and Figure 7 or Figure 8 As shown, the exhaust port 200 is located on the outer periphery of the housing 1 near the top of the smoke cartridge assembly 2. The smoke in the cavity 100 rises continuously and is discharged outward through the exhaust port 200.

[0043] It is understood that in this embodiment, the smoke emitted from the cartridge assembly 2 first enters the top area of ​​the guide shell 31. The surface of the guide shell 31 has multiple guide grooves 311. With continued airflow, the aromatherapy smoke at the top of the guide shell 31 begins to flow along the guide grooves 311 in various directions towards the outer periphery of the guide shell 31. A foam ring 34 is provided on the outer periphery of the guide shell 31, corresponding to the end of the guide groove 311. The foam ring 34 can act as a baffle for the guide groove 311 and can also absorb any remaining liquid aromatherapy smoke in the guide groove 311.

[0044] Please continue to combine Figure 2 and Figure 3A third air outlet 312 is provided at the end of part of the guide channel 311. The third air outlet 312 is correspondingly located at the end of the output channel 102, so that the airflow output from the output channel 102 can pass through the third air outlet 312 and enter the cavity 100.

[0045] Specifically, please combine Figure 3 , Figure 4 and Figure 5 The air duct control assembly includes a housing 101, an output duct 102, and a moving component 103. The moving component 103 rotates within the housing 101. The output duct 102 is located on the side of the housing 101 and communicates with it. The housing 101 is connected to the cartridge assembly 2 and the cavity 100. The other side of the housing 101 is connected to the fan 32. The housing 101 has a first air outlet 104 at a position corresponding to the output duct 102. The moving component 103 rotates to open or close the first air outlet 104.

[0046] The housing 101 is provided with a second air outlet 105 (e.g., Figure 4 and Figure 8 As shown in the figure, the second air outlet 105 is opened on the top of the housing 101, and the second air outlet 105 is located outside the movement area of ​​the moving part 103.

[0047] It is understood that the second air outlet 105 is connected to the cartridge assembly 2 via a pipe. When the moving part 103 rotates to close the first air outlet 104, all the airflow from the fan 32 is output to the cartridge assembly 2 through the second air outlet 105. When the moving part 103 rotates to open the first air outlet 104, both the first air outlet 104 and the second air outlet 105 are open. Since there is some air pressure inside the cartridge assembly 2 due to its small pores, most of the airflow from the fan 32 will enter the first air outlet 104, and a small amount of air will enter the second air outlet 105 to ensure that there is a small amount of airflow inside the cartridge assembly 2, which has just stopped working but still retains residual heat, to carry out the aromatherapy smoke.

[0048] Please continue to combine Figure 4 and Figure 5 The inner surface of the housing 101 is a cylindrical structure. The moving part 103 is in contact with the inner surface of the housing 101. Thus, the moving part 103 always maintains contact with the inner surface of the housing 101 during rotation.

[0049] It is understood that in this embodiment, the internal cylindrical structure of the receiving shell 101 allows the moving part 103 to rotate more smoothly, ensuring that the inner wall of the receiving shell 101 and the surface of the moving part 103 remain in contact, thus improving the sealing performance of the first air outlet 104. Simultaneously, since the receiving shell 101 is the first point where the air from the fan 32 reaches, the internal cylindrical structure of the receiving shell 101 allows a large amount of gas to reduce the noise caused by the collision with the original straight wall, thereby achieving a noise reduction effect.

[0050] It is understood that in other embodiments, the inner wall of the housing 101 may also adopt the original square or rectangular straight surface structure, and the moving part 103 can close or open the first air outlet 104 by rotating in the tangential direction of the wall of the housing 101.

[0051] The inner wall of the housing 101 is provided with limiting blocks 106, which are respectively located at the two ends of the moving member 103 in the rotation direction. Figure 5 As shown, the moving part 103 rotates between two limiting blocks 106.

[0052] Please combine Figure 5 and Figure 6 The moving part 103 has an outwardly protruding arc surface on the surface corresponding to the limiting block 106, and the limiting block 106 has a concave arc surface on the side corresponding to the moving part 103. The moving part 103 is inserted into the side of the limiting block 106.

[0053] Please continue to combine Figure 4 and Figure 5 The outer side of the housing 101 is also connected to a power component 107, which is connected to the moving component 103 and drives the moving component 103 to rotate.

[0054] It is understood that in this embodiment, the power component 107 is a gear driven by a motor, that is, one end of the power component 107 is provided with a first gear 1071, and the moving component 103 meshes with the first gear 1071 at the end exposed outside the receiving shell 101. Of course, in other embodiments, a pulley can also be used to drive the moving component 103 to rotate, that is, the power component 107 is configured as a belt connected to the moving component 103 based on a motor drive, as long as the moving component 103 can rotate, it is not limited here.

[0055] The power component 107 is located at the top of the outer side of the housing 101, and the output channel 102 and the fan 32 are respectively disposed on opposite sides of the housing. Thus, the power component 107, output channel 102, and fan 32 form a triangular structure on the outer surface of the housing 101. Figure 3As shown, the output channel 102 and the fan 32 are respectively located on opposite sides of the housing 101. When the first air outlet 104 is opened, the air from the fan 32 can blow directly into the first air outlet 104, increasing the air volume of the first air outlet 104.

[0056] Please combine Figure 4 and Figure 6 The moving part 103 includes a meshing part 1031, a sealing part 1032 and a connecting part 1033 arranged in sequence. The meshing part 1031 is exposed on the outside of the receiving shell 101. The sealing part 1032 is used to rotate to close or open the first air outlet 104. The connecting part 1033 passes through the side wall of the receiving shell 101 and is rotatably connected to the receiving shell 101.

[0057] The meshing part 1031 is used to connect with the power component 107. Specifically, the meshing part 1031 can be configured as a gear, a roller meshing with a belt, etc. The sealing part 1032 is an arc-shaped plate structure, and the connecting part 1033 is used to stably support the rotation of the moving component 103.

[0058] Please combine Figure 4 and Figure 6 One end of the output channel 102 is connected to the first air outlet 104, and the other end is connected to the cavity 100. The airflow passes through the first air outlet 104 and the output channel 102 in sequence, passes through the third air outlet 312 and enters the cavity 100. Continuous blowing will carry the aromatherapy smoke in the cavity 100 out of the device through the smoke exhaust port 200, forming a fragrance diffusion effect.

[0059] Compared with the prior art, the atomizing aroma diffuser provided by this utility model has the following beneficial effects:

[0060] 1. By setting the air duct control component as a rotating moving part, the rotation of the moving part opens or closes the first air outlet, thus switching the air duct. Due to the short rotational stroke, the first air outlet can be opened or closed quickly. Compared with the previous method of linear motion driven by a screw, this greatly shortens the stroke of the moving part, improves the efficiency of air duct switching and opening or closing, and makes the switching process more direct and faster. At the same time, because the stroke is shortened and the movement is simpler, the structural failure rate is lower.

[0061] 2. By designing the inner wall of the housing as a cylindrical structure, the curved inner wall reduces noise from the vertical impact of airflow compared to an internal rectangular structure, resulting in better noise reduction. Simultaneously, the cylindrical inner wall maintains constant contact with the moving parts, improving the airtightness of the moving parts to the first air outlet. Since the fan consistently blows air into the housing, when the moving parts rotate to close the first air outlet, the airflow force on the moving parts further enhances the airtightness between them and the housing.

[0062] 3. By placing the meshing part of the moving parts and the power parts on the outside of the housing, the driving meshing structure is located outside the smoke flow area. Combined with the airtightness of the housing, the meshing transmission parts will not be affected by the adhesion of liquefied aromatherapy oil during long-term use, allowing the meshing transmission to maintain stable operation during long-term use. Users do not need to disassemble and reassemble, which facilitates the long-term use of the product.

[0063] 4. The entire air duct control assembly has a closed structure, which isolates the air duct from the electronic components inside the aromatherapy device, preventing the liquefied smoke from corroding the electronic components inside the device and increasing the product's lifespan.

[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
