Description

Technical Field

[0001] This application relates to the field of air improvement equipment technology, and in particular to a fragrance diffuser component and fragrance diffuser device. Background Technology

[0002] A fragrance diffuser is a product containing built-in fragrance to diffuse its aroma into the environment. However, these diffusers often lack proper sealing to protect the fragrance, leading to risks such as leakage and spoilage. Utility Model Content

[0003] An embodiment of this application provides a fragrance diffuser component, which includes a main body and a volatile part. At least a portion of the main body and the volatile part are integrally formed. The main body and the volatile part surround a receiving cavity, and a volatile fragrance is disposed in the receiving cavity.

[0004] The volatile part has a first micropore, which is connected to the accommodating cavity and is used to connect to the external air passage, so that the volatile fragrance can be volatilized into the air passage through the first micropore, and the first micropore prevents the volatile fragrance from flowing out of the accommodating cavity.

[0005] An embodiment of this application also provides a diffuser device, which includes a housing, a piezoelectric ceramic sheet, and the above-mentioned diffuser components. The housing has an air passage inside, and the outer surface of the housing has an aroma outlet communicating with the air passage. The piezoelectric ceramic sheet is disposed in the housing.

[0006] The diffuser is connected to the housing. The piezoelectric ceramic sheet is used to generate vibration under the action of an electric field to output airflow to the evaporation part of the diffuser. The first micropore of the evaporation part is connected to the air channel, so that the volatile fragrance of the diffuser can be volatilized into the air channel through the first micropore.

[0007] The beneficial effects of the fragrance diffuser component provided in this application are:

[0008] This application utilizes a main body and an evaporation section to form a receiving cavity, and places volatile fragrances in the receiving cavity. The fragrance is volatilized and locked in through a first micropore opened in the evaporation section. Thus, the first micropore can lock the fragrance in the hole while allowing the fragrance to volatilize, thereby preventing fragrance leakage. This application also designs the main body and the evaporation section as an integral structure, thereby preventing gaps that may lead to fragrance leakage due to improper assembly, thereby further improving the sealing performance of the first shell, reducing the risk of fragrance leakage and the risk of fragrance oxidation and deterioration due to contact with air.

[0039] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0041] This application provides a fragrance diffuser component for dispersing fragrance into the surrounding environment. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural schematic diagram of the fragrance diffuser components provided in some embodiments of this application. Figure 2 yes Figure 1 A cross-sectional view of the aroma diffuser component in the embodiment.

[0042] In some embodiments, the fragrance diffuser 10 includes a diffuser shell 100 and a volatile fragrance 200 embedded in the diffuser shell 100. The diffuser shell 100 has through-holes on its surface, allowing the volatile fragrance 200 to evaporate out of the diffuser shell 100, thus enabling the fragrance diffuser 10 to diffuse its aroma to the outside. The volatile fragrance 200 is typically an oil-based fragrance, which can be in the form of a fluid, such as essential oils or perfumes, or in the form of a solid, such as a balm. In other embodiments, the volatile fragrance 200 can also be other types of fragrances capable of evaporating aroma.

[0043] The aroma diffuser assembly 10 may include a main body 110 and an evaporation section 120, which together form a receiving cavity 101 for containing volatile fragrance 200. The main body 110 may be a sealed structure to prevent leakage of the volatile fragrance 200. The evaporation section 120 has a first micropore 102 communicating with the receiving cavity 101, allowing the volatile fragrance 200 to evaporate through the micropore 102 to the outside of the aroma diffuser assembly 10. The first micropore 102 can prevent the volatile fragrance 200 from flowing out of the receiving cavity 101. The first micropore 102 may be a micrometer-sized through-hole, used to contain the volatile fragrance 200 within the hole and prevent it from dripping out of the aroma diffuser assembly 10. In other embodiments, the evaporation section 120 may also have a relatively larger through-hole for evaporation of the volatile fragrance 200, such as a millimeter-sized through-hole.

[0044] The number of evaporation sections 120 can be multiple, and the multiple evaporation sections 120 can be arranged in different regions of the main body 110 and spaced apart from each other. In other embodiments, the number of evaporation sections 120 can also be one.

[0045] The volatile fragrance 200 can be exposed within the receiving cavity 101. Typically, to prevent fragrance leakage, fragrances used in aroma-diffusing products are stored in a carrier such as oil-retaining cotton, which is then placed inside the product's outer shell. In contrast, this embodiment exposes the volatile fragrance 200 within the receiving cavity 101, directly placing it within the aroma diffuser 10 without the need for a carrier like oil-retaining cotton. This improves the utilization rate of the receiving cavity 101, potentially increasing the fragrance storage capacity of the aroma diffuser 10 or reducing its volume.

[0046] The volatile fragrance 200 is in contact with the cavity wall of the receiving cavity 101. Specifically, the volatile fragrance 200 can be disposed in contact with the evaporation section 120. In this case, since the pore size of the first micropore 102 is very small, the volatile fragrance 200 will be locked in the receiving cavity 101 or the first micropore 102, and will not drip out of the fragrance diffuser 10 through the first micropore 102. The volatile substances of the volatile fragrance 200 are in a gaseous state, and the volatile substances can evaporate out of the fragrance diffuser 10 through the first micropore 102.

[0047] The volatile fragrance 200 may also be spaced apart from the evaporation section 120. Its volatile substances can first evaporate into the receiving cavity 101, and then evaporate to the outside of the fragrance diffuser 10 through the first micropore 102. The first micropore 102 is a micrometer-sized through-hole, and its pore size can be set according to actual conditions. In some embodiments, the pore size of the first micropore 102 can be 10-100 micrometers, such as 20 micrometers, 40 micrometers, 60 micrometers, 80 micrometers, etc.

[0048] In some embodiments, the volatile fragrance 200 may be in a liquid state. The volatile fragrance 200 is flowably disposed within the receiving cavity 101 and is in direct contact with the cavity wall of the receiving cavity 101. In other words, the liquid volatile fragrance 200 can be directly stored within the receiving cavity 101 without being stored through a carrier such as a liquid-retaining cotton. The volatile fragrance 200 can contact the evaporation section 120, so that the aroma emitted by the volatile fragrance 200 can be output to the outside of the fragrance diffuser 10 through the first micropore 102, and the first micropore 102 can lock the droplets based on capillary effect, preventing leakage of the volatile fragrance 200. In other embodiments, the volatile fragrance 200 may also be stored in a solid state within the receiving cavity 101, and the first micropore 102 can lock the volatile fragrance 200 within the pore when it at least partially melts into a liquid state.

[0049] In this embodiment, at least a portion of the main body 110 and the evaporating part 120 can be an integral structure, thereby preventing gaps that could lead to fragrance leakage due to improper assembly of the main body 110 and the evaporating part 120. This prevents leakage of the volatile fragrance 200 exposed in the receiving cavity 101, which not only reduces the risk of fragrance leakage but also reduces the risk of fragrance oxidation and deterioration due to contact with air, thus extending the service life of the fragrance diffuser assembly 10. In other embodiments, the main body 110 and the evaporating part 120 can also be separate structures.

[0050] Here, an integral structure refers to a structure that cannot be divided without destructive operation, as opposed to a split structure that can be connected as a whole through snap-fit ​​connections, threaded connections, or other methods. There are various ways in which at least a portion of the main body 110 and the evaporation section 120 can form an integral structure. In some embodiments, at least a portion of the main body 110 can be integrally injection molded with the evaporation section 120. In other embodiments, at least a portion of the main body 110 can be integrally formed with the evaporation section 120 through methods such as, but not limited to, hot-melt or welding.

[0051] In some embodiments, the accommodating cavity 101 includes a cavity bottom wall 130 and a cavity side wall 150. A portion of the cavity bottom wall 130 has first micropores 102 forming a evaporation section, while another portion of the cavity bottom wall 130 cooperates with the cavity side wall 150 to form at least a partial main body portion 110. The cavity bottom wall 130 and the cavity side wall 150 can be an integral structure. In other embodiments, the cavity bottom wall 130 and the cavity side wall 150 can also be separate structures.

[0052] The shapes of the cavity bottom wall 130 and the cavity side wall 150 can be designed as needed and can be used to form part or the whole of the main body 110. For example, the cavity bottom wall 130 can be flat and the cavity side wall 150 can be hemispherical, and the two can be used to form the entire main body 110.

[0053] For example, both the bottom wall 130 and the side wall 150 of the cavity can be flat, and they can be fitted together to form part of the main body 110. The accommodating cavity 101 may also include a top wall, with the bottom wall 130 and the top wall 140 disposed opposite to each other, and the side wall 150 connected between the bottom wall 130 and the top wall 140. The following description mainly uses this as an example. In other embodiments, the accommodating cavity 101 may also include only one wall, such as a spherical wall, which can form the main body 110 and the evaporation section 120.

[0054] The bottom wall 130 and the side wall 150 of the cavity can be an integral structure to form part of the main body 110. A portion of the bottom wall 130 of the aroma diffuser assembly 10 can have first micropores 102 to form a volatile portion 120. Another portion of the bottom wall 130 of the aroma diffuser assembly 10 can cooperate with the top wall 140 and the side wall 150 to form the main body 110. In other words, the volatile portion 120 and part of the main body 110 can cooperate to form a wall of the aroma diffuser shell 100.

[0055] In this embodiment, by creating a first micropore 102 in a portion of the cavity bottom wall 130, a portion of the cavity bottom wall 130 forms a volatile portion 120, while another portion forms a partial main body 110. This ensures that only a portion of the volatile fragrance 200 in contact with the cavity bottom wall 130 evaporates, preventing excessively high fragrance diffusion efficiency of the fragrance diffuser 10. In other embodiments, the entire cavity bottom wall 130 may form a volatile portion 120. The fragrance diffusion efficiency of the fragrance diffuser 10 can be adjusted by regulating the proportion of the volatile portion 120 within the fragrance diffuser shell 100.

[0056] Both the top wall 140 and the bottom wall 130 of the cavity can be flat plates, allowing the volatile fragrance 200 to be stably stored in the receiving cavity 101 when either the top wall 140 or the bottom wall 130 is placed on an external plane. For example, both the top wall 140 and the bottom wall 130 can be square plates, and the side wall 150 can be connected between the sides of the top wall 140 and the sides of the bottom wall 130. The bends in the side wall 150 can form rounded chamfers to improve safety. Of course, the bends in the side wall 150 can also form right angles.

[0057] The top wall 140 and bottom wall 130 of the cavity can also be designed in other shapes as needed, such as both being designed as circular plates, to meet the usage requirements of the diffuser assembly 10. In other embodiments, at least one of the top wall 140 and bottom wall 130 of the cavity can also have a curvature, such as being hemispherical. The diffuser shell 100 can also be designed in other shapes as needed, for example, the diffuser shell 100 may include only one curved wall.

[0058] In this embodiment, the outer surface of the cavity bottom wall 130 can be a flat surface, and the evaporation portion 120 and part of the main body portion 110 constituting the cavity bottom wall 130 are coplanarly arranged. In other embodiments, the outer surface of the cavity bottom wall 130 can also be an uneven surface, and the evaporation portion 120 and part of the main body portion 110 constituting the cavity bottom wall 130 can be arranged in a concave-convex shape, for example, the evaporation portion 120 can protrude from the main body portion 110.

[0059] In some embodiments, the main body 110 may be an integral structure, and the main body 110 is completely integrated with the evaporation section 120. In other embodiments, the main body 110 is a split structure, having a portion that is integrated with the evaporation section 120 and another portion connected to this portion.

[0060] Optionally, the main body 110 includes a top cover 111 and a bottom shell 112. The bottom shell 112 has a receiving groove 103, which forms a receiving cavity 101. The top cover 111 covers the receiving groove 103 and is connected to the bottom shell 112, and the connection method is, for example, but not limited to, snap-fit ​​or threaded connection. The evaporation section 120 forms an integral structure with the groove wall of the receiving groove 103, for example, it forms an integral structure with the bottom wall of the receiving groove 103.

[0061] In some embodiments, the volatile fragrance 200 can be injected into the receiving cavity 101 after the diffuser shell 100 is integrally formed. The main body 110 may have an injection hole through which the volatile fragrance 200 can be injected into the receiving cavity 101. The diffuser assembly 10 may also include a sealing plug, which may be interference-fitted into the injection hole to prevent leakage of the volatile fragrance 200. In other embodiments, the diffuser assembly 10 may also seal the injection hole in other ways, such as using a material of the same material as the main body 110 to seal the injection hole, and using methods such as heat fusion to integrate the material with the main body 110.

[0062] In other embodiments, the volatile fragrance 200 may be injected into the diffuser shell 100 before it is integrally formed. For example, in this embodiment, the volatile fragrance 200 may be placed in the receiving groove 103 of the bottom shell 112 before the bottom shell 112 is connected to the top cover 111. In other embodiments, the bottom shell 112 and the top cover 111 may also be integrally formed.

[0063] Understandably, all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0064] Please see Figure 2 and Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the planar structure of the aroma diffuser component in the embodiment.

[0065] In some embodiments, the fragrance diffuser 10 includes a liquid-conducting medium 121 for forming an evaporation section 120. The liquid-conducting medium 121 is a porous material that can be integrally formed with the main body 110. The pores of the liquid-conducting medium 121 itself serve as the aforementioned first micropores 102 for discharging the volatile substances of the volatile fragrance 200. In other words, the liquid-conducting medium 121 itself has first micropores 102.

[0066] The main function of the liquid-conducting medium 121 is to conduct the volatile fragrance 200. Taking the volatile fragrance 200 as an oil as an example, the liquid-conducting medium 121 can conduct the oil using its own micropores, and rely on the capillary force of its own micropores to lock the oil and prevent leakage. The liquid-conducting medium 121 can be a corrosion-resistant porous material, such as, but not limited to, porous glass, porous ceramics, and porous plastics.

[0067] In some embodiments, the liquid-conducting medium 121 can be made of ceramic or plastic. The pore size of the first micropore 102 can be 10-100 micrometers, such as 20 micrometers, 40 micrometers, 60 micrometers, 80 micrometers, etc. The porosity of the liquid-conducting medium 121 can be 30%-60%, such as 35%, 40%, 45%, 50%, etc. Porosity refers to the percentage of the volume of pores in a material to the total volume of the material in its natural state, and can be used to reflect the density of the material. The liquid-conducting medium 121 can be processed, but is not limited to, by a sintering process.

[0068] In other embodiments, the liquid guiding medium 121 can be made of glass. The pore size of the first micropore 102 can be 10-100 micrometers, such as 20 micrometers, 40 micrometers, 60 micrometers, 80 micrometers, etc. The pore spacing of the liquid guiding medium 121 can be 10-150 micrometers, such as 30 micrometers, 60 micrometers, 90 micrometers, 120 micrometers, etc. The pore spacing refers to the distance between the centers of two adjacent pores in an object.

[0069] The liquid-conducting medium 121 can be processed by mechanical methods such as laser, chemical etching, or a combination of laser and chemical etching, but is not limited to these methods. For example, the liquid-conducting medium 121 can also be processed by stretching and cutting glass with capillary tubes. In other embodiments, the liquid-conducting medium 121 can also be other materials capable of performing liquid-conducting functions, such as silicone, and is not limited to the above embodiments.

[0070] In this embodiment, the liquid guiding medium 121 can be integrated with the main body 110 by means of, but not limited to, hot melting, ultrasonic welding, etc. In some embodiments, the material of the liquid guiding medium 121 can be the same as the material of the main body 110. In other embodiments, the material of the liquid guiding medium 121 can be different from the material of the main body 110.

[0071] In other embodiments, the evaporation section 120 and at least a portion of the main body 110 may also be formed from a single piece of material, in which case both are made of the same material. It is understood that the above description regarding the liquid-conducting medium 121 also applies to embodiments where the evaporation section 120 is not formed from the liquid-conducting medium 121. Please refer to... Figure 4 , Figure 4 This is a cross-sectional structural schematic diagram of a diffuser component provided in other embodiments of this application.

[0072] In some embodiments, the first micropores 102 may be formed in a portion of the diffuser shell 100. The portion of the diffuser shell 100 with the first micropores 102 forms the evaporation section 120, while the portion without the first micropores 102 forms the main body section 110. The plurality of first micropores 102 may be arranged in an array. In other embodiments, the plurality of first micropores 102 may also be arranged in other ways, and the specific arrangement is not limited.

[0073] Optionally, the diffuser shell 100 includes an upper cover 111 and a bottom shell 112 surrounding a cavity 101, with a first micropore 102 formed in the bottom shell 112. The upper cover 111 forms a partial main body portion 110, and the bottom shell 112 forms a volatile portion 120 and another part of the main body portion 110. The upper cover 111 can be connected to the bottom shell 112.

[0074] The top cover 111 and the bottom shell 112 can both be made of dense materials, such as, but not limited to, glass, ceramic, corrosion-resistant plastic, etc.

[0075] In some embodiments, the bottom shell 112 can be made of plastic, and the volatile portion 120 and part of the main body 110 formed by the bottom shell 112 can be integrated through processes such as injection molding. In other embodiments, the bottom shell 112 can be made of glass. In this application embodiment, a bottom shell 112 with a volatile portion 120 and part of the main body 110 can be formed by laser processing a piece of glass, or by stretching and then cutting glass with capillary tubes to form a bottom shell 112 with a volatile portion 120 and part of the main body 110.

[0076] In other embodiments, the diffuser shell 100 can be a single-piece structure; in other words, the upper cover 111 and the bottom shell 112 can be a single-piece structure, thus the main body 110 and the evaporation part 120 can be a single-piece structure. For example, the diffuser shell 100 can be made of plastic, and in this embodiment, the integration of the main body 110 and the evaporation part 120 can be achieved through processes such as injection molding. Alternatively, the diffuser shell 100 can be made of glass, and in this embodiment, the integration of the main body 110 and the evaporation part 120 can be achieved through processes such as blow molding and hot-melt molding.

[0077] The evaporation section 120 can be made of ceramic or plastic, the pore size of the first micropore 102 can be 10-100 micrometers, and the porosity of the evaporation section 120 can be 30%-60%. Alternatively, the evaporation section 120 can be made of glass, the pore size of the first micropore 102 can be 10-100 micrometers, and the pore spacing of the evaporation section 120 can be 10-150 micrometers.

[0078] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0079] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the planar structure of the fragrance diffuser assembly provided in some embodiments of this application. Figure 6 yes Figure 5 A cross-sectional view of the aroma diffuser component in the embodiment.

[0080] In some embodiments, the diffuser assembly 10 may further include a cover 210, which covers the evaporation section 120 and at least a portion of the main body section 110. For example, the cover 210 may cover the bottom shell 112 of the diffuser shell 100, or the cover 210 may cover the entire diffuser shell 100.

[0081] The cover 210 has a second micropore 201, which communicates with the first micropore 102 to allow the volatile fragrance 200 to evaporate. The diameter of the second micropore 201 can be larger than that of the first micropore 102. In some embodiments, the second micropore 201 may be located on the portion of the cover 210 that covers the evaporation portion 120. In other embodiments, the second micropore 201 may be located on the portion of the cover 210 that covers the evaporation portion 120, and on another portion of the cover 210 that covers at least a portion of the main body 110, to disperse the volatile substances of the fragrance 200. For example, the cover 210 may cover the bottom wall 130 and the side wall 150 of the cavity, with the second micropore 201 located on the portion covering the bottom wall 130.

[0082] The multiple second micropores 201 can be arranged in an array. In other embodiments, the multiple second micropores 201 can also be arranged in other ways to achieve the evaporation function, and the specific method is not limited.

[0083] Optionally, the cover 210 is provided with a first mounting groove 202, the evaporation part 120 and at least a portion of the main body 110 are disposed in the first mounting groove 202, and the main body 110 is interference-fitted with the groove wall of the first mounting groove 202. The first mounting groove 202 may have a bottom wall and a side wall, the bottom wall and the side wall being bent and connected. The side wall may cover at least a portion of the cavity side wall 150, and the bottom wall may cover the cavity bottom wall 130. A plurality of second micropores 201 may be distributed on the bottom wall of the first mounting groove 202.

[0084] In other embodiments, the cover 210 may also have other shapes; for example, the first mounting groove 202 of the cover 210 may have an integral arcuate wall. The cover 210 may also be connected to the diffuser shell 100 in other ways, such as, but not limited to, adhesive bonding.

[0085] In this embodiment of the application, by covering the evaporating part 120 and at least part of the main body 110 with the cover 210, the strength of the diffuser component 10 can be enhanced, preventing leakage of the diffuser component 10 due to external forces during use. It can also prevent the evaporating part 120 from directly contacting external components during use, which is beneficial to further prevent leakage of volatile fragrance 200.

[0086] In some embodiments, the main body 110 may be provided with a first connecting portion for detachable connection between the aroma diffuser assembly 10 and an external component. The structure of the first connecting portion can be set according to specific circumstances. For example, the aroma diffuser assembly 10 may include a first magnetic member 310, which can serve as the first connecting portion for detachable connection with the external component by magnetic adsorption. In other embodiments, the first connecting portion may also be, for example, but not limited to, a snap-fit, slot, slide rail, or other structure, enabling the aroma diffuser assembly 10 to be detachably connected to the external component in other ways.

[0087] Taking the aroma diffuser assembly 10 including a first magnetic member 310 as an example, the first magnetic member 310 can be disposed on the outer surface of the aroma diffuser shell 100, for example, but not limited to, such as Figure 6 The first magnetic member 310 is disposed on the cavity sidewall 150 as shown. The cover 210 can cover the first magnetic member 310, so that the first magnetic member 310 forms a hidden structure of the aroma diffuser assembly 10, which helps to improve the appearance consistency of the aroma diffuser assembly 10 and can prevent the first magnetic member 310 from falling off. In other embodiments, the first magnetic member 310 can also be disposed on the outer surface of the cover 210.

[0088] This application also provides a fragrance diffuser. The fragrance diffuser may include the fragrance diffuser component 10 described above. Please refer to the above text. Figure 7 , Figure 7 This is a cross-sectional structural schematic diagram of the aroma diffuser provided in some embodiments of this application.

[0089] In some embodiments, the aroma diffuser 20 includes an aroma diffuser assembly 10, a housing 11, and an air delivery mechanism 400.

[0090] The aroma diffuser assembly 10 may include a main body 110 and a volatile part 120. The main body 110 and the volatile part 120 surround a receiving cavity 101, and a volatile fragrance 200 is disposed within the receiving cavity 101. The volatile part 120 may have a first micropore 102, which communicates with the receiving cavity 101 and prevents the volatile fragrance 200 from flowing out of the receiving cavity 101. The specific structure of the aroma diffuser assembly 10 has been described in detail above and will not be repeated here.

[0091] The housing 11 is disposed on the aroma diffuser assembly 10. An aroma outlet 302 is provided on the outer surface of the housing, and an air passage 303 is provided inside the housing 11, with the aroma outlet 302 communicating with the air passage 303. A first micropore 102 also communicates with the air passage 303, allowing volatile fragrance 200 to evaporate into the air passage 303 through the first micropore 102. An air supply mechanism 400 is disposed in the housing 11 and is used to output airflow to the evaporation section 120. The specific structure of the air supply mechanism 400 will be described below.

[0092] The housing 11 can be mounted on the aroma diffuser 10 in, but is not limited to, the following ways: the housing 11 is fixedly connected to the aroma diffuser 10, such as by bonding or welding; the housing 11 is detachably connected to the aroma diffuser 10, such as by snap-fit ​​or abutment; the housing 11 is integrally formed with the aroma diffuser 10, such as integrally formed with the main body 110 or integrally formed with the evaporation part 120. The mounting method of the housing 11 on the aroma diffuser 10 can be designed as needed.

[0093] This application embodiment provides an air supply mechanism 400 within the housing 11 and an air passage 303 within the housing 11. The air supply mechanism 400 generates an airflow within the air passage, allowing the aroma output from the fragrance diffuser assembly 10 connected to the housing 11 to be efficiently delivered to the outside under the influence of the airflow. Thus, the fragrance diffuser 20 achieves a highly efficient fragrance diffusion function. This application also utilizes the main body 110 and the evaporation section 120 to form a receiving cavity 101, and places the volatile fragrance 200 within the receiving cavity 101. The fragrance is both volatilized and contained through a first micropore 102 formed in the evaporation section 120, thereby preventing fragrance leakage while simultaneously allowing fragrance volatilization.

[0094] The specific structure of the housing 11 and the connection method between the air supply mechanism 400 and the housing 11 can be set as needed.

[0095] Please refer to the above text. Figures 8 to 11 , Figure 8 This is a three-dimensional structural schematic diagram of the aroma diffuser provided in some embodiments of this application. Figure 9 yes Figure 8 An exploded view of the aroma diffuser in the embodiment. Figure 10 This is a cross-sectional structural schematic diagram of the aroma diffuser provided in some embodiments of this application. Figure 11 yes Figure 10 A partial cross-sectional structural diagram of the aroma diffuser in the embodiment.

[0096] In some embodiments, the aroma diffuser 20 includes an aroma diffuser component 10 and a main unit 21, wherein the aroma diffuser component 10 is connected to the main unit 21.

[0097] The main unit 21 includes a main unit housing 330, which can serve as the housing 11. The aroma diffuser assembly 10 is connected to the main unit housing 330. In other words, the outer surface of the main unit housing 330 can be provided with an aroma outlet 302, and the interior of the main unit housing 330 can be provided with an air passage 303. The air supply mechanism 400 can be disposed within the main unit housing 330.

[0098] Optionally, the aroma diffuser 10 is detachably connected to the main unit 21. The aroma diffuser 10 includes a first connecting portion, and the main unit 21 includes a second connecting portion. The first and second connecting portions are adapted to each other, allowing for a detachable connection between the aroma diffuser 10 and the main unit 21. The specific structures of the first and second connecting portions can be customized as needed. In other embodiments, the aroma diffuser 10 and the main unit 21 can be connected in other ways, not limited to a detachable connection; for example, the aroma diffuser 10 can be glued to the main unit 21. The following description primarily uses a detachable connection between the aroma diffuser 10 and the main unit 21 as an example.

[0099] The diffuser assembly 10 may include a first magnetic element 310, which serves as a first connecting part. The main unit 21 may include a second magnetic element 320, which serves as a second connecting part. The first magnetic element 310 and the second magnetic element 320 are two components capable of magnetic attraction, and their specific materials are not limited. For example, both can be magnets, or one can be a magnet and the other can be made of iron. The diffuser assembly 10 and the main unit 21 can be detachably connected through the magnetic attraction of the first magnetic element 310 and the second magnetic element 320.

[0100] In other embodiments, the first connecting part and the second connecting part may also be designed with other structures, such as a matching mortise and tenon structure, a threaded structure, etc., and there is no specific limitation. The following description mainly takes the first connecting part as the first magnetic member 310 and the second connecting part as the second magnetic member 320 as examples.

[0101] In some embodiments, the main unit 21 may be provided with a second mounting groove 301, and the aroma diffuser component 10 is detachably disposed in the second mounting groove 301 to reduce the volume of the aroma diffuser 20. The outer surface of the aroma diffuser component 10 may fit against the groove wall of the second mounting groove 301 to improve the appearance consistency of the aroma diffuser 20. Of course, the second mounting groove 301 is not a necessary structure of the main unit 21 in this embodiment, and the main unit 21 may be designed with other shapes as needed. In other embodiments, the aroma diffuser component 10 may also be fixedly connected to the main unit 21.

[0102] The second mounting groove 301 may have a bottom wall and side walls. The second magnetic member 320 may be embedded in the side wall of the second mounting groove 301, allowing it to be a hidden structure of the main unit 21, avoiding affecting the appearance consistency of the main unit 21 and preventing it from falling off. The first magnetic member 310 may be disposed on the cavity side wall 150, which may be opposite to the side wall of the second mounting groove 301. A portion of the diffuser assembly 10's cover 210 may be located between the first magnetic member 310 and the second magnetic member 320, with the first magnetic member 310 and the second magnetic member 320 magnetically adsorbed at intervals. In other embodiments, the first magnetic member 310 and the second magnetic member 320 may also be in contact.

[0103] The diffuser component 10 can also be called an oil cartridge, fragrance box, etc. In this embodiment, the diffuser component 10 is detachably connected to the main unit 21, allowing the diffuser device 20 to be replaced with a new diffuser component 10 as needed to meet user requirements and extend the lifespan of the diffuser device 20. In some applications, when the volatile fragrance 200 in the diffuser component 10 installed in the main unit 21 is exhausted, the diffuser device 20 can be replaced with a new diffuser component 10 to extend its lifespan. In other applications, the diffuser device 20 can be replaced with diffuser components 10 containing different volatile fragrances 200 according to the user's fragrance preferences, thereby enriching the types of diffuseable fragrances available from the diffuser device 20.

[0104] In this embodiment, the structure and function of the host 21 can be configured as needed. For example, the host 21 may include an installation structure, and the aroma diffuser 10 can be stably installed externally by connecting to the host 21. Alternatively, the host 21 may include an atomizing structure for atomizing the volatile fragrance 200 of the aroma diffuser 10 to improve aroma diffusion efficiency. In other embodiments, the aroma diffuser 10 is not limited to application in the aroma diffuser 20; for example, the aroma diffuser 10 can be placed on a table for use.

[0105] In some embodiments, the aroma diffuser 20 may actively supply air to accelerate the evaporation of the volatile fragrance 200, and this will be used as an example in the following description. In other embodiments, the aroma diffuser 20 may also allow the volatile fragrance 200 to evaporate naturally. Please refer to [reference needed]. Figures 9 to 13 , Figure 12 This is a cross-sectional structural diagram of a host provided in some embodiments of this application. Figure 13 yes Figure 12 A schematic diagram of the planar structure of the main unit in the embodiment. Optionally, the main unit 21 includes an air supply mechanism 400, which is used to generate airflow to improve the evaporation efficiency of the volatile fragrance 200 of the fragrance diffuser 10. The specific structure of the air supply mechanism 400 will be described below.

[0106] The main unit 21 may have an aroma outlet 302 on its outer surface, which is used to output the aroma of the diffuser 20. The aroma outlet 302 may be located on the side of the main unit 21, for example, but not limited to, and the side of the main unit 21 may be bent and connected to the outer surface of the cavity top wall 140 of the diffuser assembly 10. The main unit 21 may have an air passage 303 communicating with the aroma outlet 302 inside, and the airflow generated by the air supply mechanism 400 is used to flow through the air passage 303 to the aroma outlet 302. The outer surface of the main unit 21 may also have an air inlet 304, which communicates with the air passage 303. Outside air can enter the air passage 303 through the air inlet 304 and form an airflow. The air inlet 304 may be located on the back of the main unit 21, for example, but not limited to, and the back of the main unit 21 and the outer surface of the cavity top wall 140 may be two opposing surfaces.

[0107] One end of the air duct 303 can be connected to the fragrance outlet 302, and the other end can be connected to the air inlet 304. The air outlet of the air supply mechanism 400 can be located in the air duct 303, for example, but not limited to, at one end of the air duct 303, to generate an airflow toward the fragrance outlet 302. In other embodiments, the air outlet of the air supply mechanism 400 can also be located outside the air duct 303, and the airflow it generates can first flow into the air duct 303, and then be output through the fragrance outlet 302.

[0108] The evaporation section 120 of the aroma diffuser 10 can face the air passage 303. The air passage 303 is connected to the first micropore 102 of the aroma diffuser 10, so that the aroma output through the first micropore 102 can enter the air passage 303, and then be output through the aroma outlet 302 under the action of the airflow. The airflow flowing in the air passage 303 can also improve the output efficiency of the aroma, which is beneficial to improving the volatilization efficiency of the volatile fragrance 200.

[0109] In this design, the gap between the evaporation section 120 and the main unit 21 connects to the air passage 303, allowing the aroma output from the evaporation section 120 through this gap to enter the air passage 303. When airflow occurs within the air passage 303, a pressure difference is created, accelerating the entry of aroma from the evaporation section 120 into the air passage 303, thereby improving the diffusion efficiency of the aroma diffuser 20. In other embodiments, the aroma diffuser component 10 can also be tightly fitted to the main unit 21, eliminating the need for a gap between them.

[0110] In some embodiments, the surface of the main unit 21 facing the aroma diffuser 10 may have an inlet hole 305, through which the air passage 303 communicates with the first micropore 102. There may be multiple inlet holes 305, and the arrangement of these multiple inlet holes 305 may be, for example, but not limited to... Figure 13The array arrangement is shown. The diameter of the input hole 305 can be 1-5mm, such as 2mm, 3mm, 4mm, etc.

[0111] In other embodiments, the air passage 303 of the main unit 21 may also be exposed to the aroma diffuser 10, so that the aroma output by the aroma diffuser 10 can be directly input into the air passage 303. In this embodiment, a portion of the surface of the main unit 21 is covered with at least a portion of the volatile part 120, and multiple input holes 305 are formed on this portion of the surface, so that the aroma output through the first micropore 102 can enter the air passage 303 through the multiple input holes 305, thereby achieving both dispersed input of aroma and improving the air tightness of the air passage 303, which is beneficial to improving the aroma uniformity of the aroma diffuser 20.

[0112] Understandably, in some embodiments, the aroma diffuser 10 includes the aforementioned cover 210, which covers the evaporation section 120 and is provided with a second micropore 201 communicating with the first micropore 102. In this case, the air passage 303 can communicate with the first micropore 102 through the second micropore 201. For example, the first micropore 102, the second micropore 201, the input port 305, and the air passage 303 can be sequentially connected. In other embodiments, the surface of the evaporation section 120 can form part of the outer surface of the aroma diffuser 10. In this case, the first micropore 102 can be directly connected to the input port 305 or the air passage 303.

[0113] Optionally, the main unit 21 further includes a first cover plate 340. The first cover plate 340 is disposed on the main unit housing 330 and forms a portion of the surface of the main unit 21 facing the aroma diffuser assembly 10. The first cover plate 340 covers at least a portion of the evaporation section 120 and has a plurality of inlet holes 305. In some embodiments, the first cover plate 340 and the main unit housing 330 are separate structures, with the first cover plate 340 connected to the main unit housing 330 by means of, but not limited to, snap-fit, welding, or bonding. In other embodiments, the first cover plate 340 and the main unit housing 330 are integral structures.

[0114] Optionally, the main unit 21 includes a main unit housing 330, a first cover plate 340, and a second cover plate 350. The main unit housing 330 has a hollow structure. The first cover plate 340 and the second cover plate 350 are respectively disposed on opposite sides of the main unit housing 330, forming an air passage 303 with the main unit housing 330. The first cover plate 340 may have an inlet hole 305, the second cover plate 350 may have an air inlet 304, and the main unit housing 330 may have an aroma outlet 302. An air supply mechanism 400 may be disposed in the main unit housing 330 and fixedly connected to it. In other embodiments, the main unit 21 may also be designed with other structures as needed, and the aforementioned first cover plate 340 and second cover plate 350 are not essential structures of the main unit 21.

[0115] In this embodiment, when the air supply mechanism 400 is in working condition, it can accelerate the flow of air in the air passage 303, thereby accelerating the flow speed of air on the surface of the aroma diffuser 10 used for volatile aroma, so that the aroma output by the aroma diffuser 10 can be quickly diffused to the outside of the main unit 21, achieving the effect of rapid aroma diffusion of the aroma diffuser 20.

[0116] In some embodiments, the main unit 21 may include a battery 360, which is electrically connected to the air delivery mechanism 400 and used to power the air delivery mechanism 400. The battery 360 may be disposed inside the main unit housing 330. In other embodiments, the main unit 21 may also be designed as an external power supply structure, and the air delivery mechanism 400 may be electrically connected to an external power source using a wire. This embodiment, by designing the main unit 21 as a built-in power supply structure, facilitates the portability and use of the aroma diffuser 20.

[0117] The main unit 21 may include a control board 370. The control board 370 may include a circuit board. The control board 370 is connected to the air supply mechanism 400 and is used to control the operating status of the air supply mechanism 400, such as controlling the start / stop and operating power of the air supply mechanism 400. Optionally, the battery 360 can be electrically connected to the air supply mechanism 400 through the control board 370.

[0118] In other embodiments, housing 11 may be another component besides the main unit housing 330. See also Figure 14 and Figure 15 , Figure 14 This is an exploded structural diagram of a fragrance diffuser provided in some other embodiments of this application. Figure 15 yes Figure 14 A schematic diagram of the cross-sectional structure of the aroma diffuser in the embodiment. The aroma diffuser 20 includes an aroma diffuser component 10 and a housing 11.

[0119] In some embodiments, the housing 11 is disposed on the aroma diffuser assembly 10. For example, the housing 11 may be connected to at least one of the main body 110 and the evaporating part 120, or the housing 11 may be integrally formed with at least one of the main body 110 and the evaporating part.

[0120] The housing 11 has an air passage 303 inside, and an aroma outlet 302 communicating with the air passage 303 on its outer surface. Optionally, the outer surface of the housing 11 also has an air inlet 401 communicating with the air passage 303. The air inlet 401 communicates with the air passage 303, so that outside air can enter the air passage 303 from the air inlet 401 under the action of the air supply mechanism 400, and flow out of the air passage 303 through the aroma outlet 302.

[0121] An air supply mechanism 400 is disposed within the housing 11. Optionally, the air supply mechanism 400 is disposed within an air duct 303. The inner cavity of the housing 11 can serve as the air duct 303. In other embodiments, the inner cavity of the housing 11 can be divided into multiple spaces, with some spaces serving as the air duct 303 and the air supply mechanism 400 disposed in another portion of the space, outside the air duct 303.

[0122] The aroma diffuser 20 also includes a main unit 21, which includes a main unit housing 330. The housing 11 can be connected to the main unit housing 330. Optionally, the housing 11 and the main unit housing 330 are detachably connected, and the connection method is, for example, but not limited to, snap-fit, magnetic attraction, etc. The housing 11 can be fixed to the aroma diffuser component 10, and the aroma diffuser component 10 can be detachably connected to the main unit housing 330 via the housing 11. The upper surface of the main unit housing 330 may be provided with a placement groove 306, and the housing 11 is detachably installed in the placement groove 306 to achieve connection with the main unit housing 330. Of course, the shape of the main unit housing 330 is not limited to this; for example, the surface of the main unit housing 330 connected to the housing 11 can be flat, without the placement groove 306. In other embodiments, the housing 11 can also be fixedly connected to the main unit housing 330.

[0123] The following description mainly uses the example of the housing 11 being fixed to the aroma diffuser assembly 10 and detachably connected to the main unit housing 330.

[0124] The host unit 21 may further include a drive mechanism 380, which is electrically connected to the air supply mechanism 400 and is used to drive the air supply mechanism 400 to generate airflow. In some embodiments, the drive mechanism 380 may be the control board 370 described above. In other embodiments, the drive mechanism 380 may also be other electronically controlled mechanisms.

[0125] Optionally, the air supply mechanism 400 and the drive mechanism 380 are connected by a contact-type conductive connection. For example... Figure 15 As shown, the housing 11 may be provided with a pin 402, which is connected to the air supply mechanism 400 and protrudes from the surface of the housing 11. When the housing 11 is connected to the main housing 330, the pin 402 will contact and conduct with the electrodes exposed on the surface of the main housing 330 to realize the electrical connection between the air supply mechanism 400 and the drive mechanism 380.

[0126] Of course, the electrical connection structure between the air supply mechanism 400 and the drive mechanism 380 is not limited to this. For example, the ejector pin 402 can be set on the surface of the main housing 330, or the air supply mechanism 400 can be electrically connected to the drive mechanism 380 through a lead wire.

[0127] Optionally, the host unit 21 also includes a battery 360, which is electrically connected to the drive mechanism 380. In other embodiments, the host unit 21 may also be electrically connected to an external power source, without an internal power source.

[0128] In summary, in the embodiments of this application, the air supply mechanism 400 and the air duct 303 can be disposed on the main unit 21 (the housing 11 is the main unit housing 330) or disposed on the aroma diffuser 10 (the housing 11 is not the main unit housing 330, but is disposed on the aroma diffuser 10). The aroma diffuser 10 can achieve efficient aroma diffuser by means of the air supply mechanism 400 and the air duct 303.

[0129] The following description mainly uses the example of the air supply mechanism 400 and air duct 303 being disposed on the main unit 21 to illustrate the specific structure of the air supply mechanism 400. It can be understood that the specific structure of the air supply mechanism 400 described below also applies to embodiments in which the air supply mechanism 400 is disposed on the aroma diffuser assembly 10.

[0130] Please combine Figure 12 See Figures 16 to 18 , Figure 16 This is a schematic plan view of the air supply mechanism provided in some embodiments of this application. Figure 17 yes Figure 16 A cross-sectional structural diagram of the air supply mechanism in the embodiment. Figure 18 yes Figure 16 An exploded view of the air supply mechanism in the embodiment. It should be noted that the air supply mechanism 400 represents the part of the main unit 21 used to realize the air supply function, and does not represent a separate device; the air supply mechanism 400 is part of the main unit 21.

[0131] The air supply mechanism 400 includes a piezoelectric ceramic plate 410. The piezoelectric ceramic plate 410 is used to generate vibration under the action of an electric field to output airflow to the evaporation section 120. The airflow generated by the piezoelectric ceramic plate 410 can flow in the air passage 303 and drive the aroma output by the aroma diffuser 10 to be output from the aroma outlet 302. The piezoelectric ceramic plate 410 can be disposed in the housing 11, for example, in the main housing 330.

[0132] The principle behind the piezoelectric ceramic sheet 410 generating airflow is that piezoelectric ceramics exhibit the inverse piezoelectric effect. When an electric field is applied to the surface of the piezoelectric ceramic, it deforms. Utilizing the inverse piezoelectric effect, this embodiment applies an alternating voltage to both ends of the piezoelectric ceramic sheet 410, causing it to undergo periodic expansion and contraction vibrations. As the piezoelectric ceramic sheet 410 continues to vibrate, it pushes the surrounding air to form an airflow.

[0133] This embodiment of the application sets a piezoelectric ceramic sheet 410 inside the housing 11, and generates airflow by controlling the vibration of the piezoelectric ceramic sheet 410. This not only enables the diffuser 20 to produce fragrance efficiently, but also eliminates the need for a large air supply device such as a fan, thus having the advantages of small size and low power consumption.

[0134] The aforementioned battery 360 and / or control board 370 can be electrically connected to the piezoelectric ceramic sheet 410. The battery 360 can provide the power required to apply the electric field. The control board 370 can control the vibration frequency of the piezoelectric ceramic sheet 410, for example, controlling the piezoelectric ceramic sheet 410 to stop vibrating, vibrate at a low frequency, or vibrate at a high frequency, to adjust the airflow efficiency, and thus adjust the fragrance extraction efficiency.

[0135] Optionally, the aroma diffuser 20 also includes a diaphragm 420. The diaphragm 420 can be disposed within the housing 11 and connected to the piezoelectric ceramic sheet 410, the connection method being, for example but not limited to, bonding. The piezoelectric ceramic sheet 410 is used to drive the diaphragm 420 to vibrate under the action of an electric field, thereby generating airflow and improving airflow generation efficiency. The diaphragm 420 can be a thin film element used to vibrate under the action of the piezoelectric ceramic sheet 410. The diaphragm 420 can be connected to the side of the piezoelectric ceramic sheet 410 facing the air passage 303.

[0136] In this embodiment, the area of ​​the diaphragm 420 can be greater than or equal to the area of ​​the piezoelectric ceramic sheet 410 to improve airflow generation efficiency. In other embodiments, the area of ​​the diaphragm 420 can also be smaller than the area of ​​the piezoelectric ceramic sheet 410. The host 21 can also use the piezoelectric ceramic sheet 410 itself to drive air to form an airflow without providing the diaphragm 420. The following description mainly uses the example of providing the diaphragm 420 on the piezoelectric ceramic sheet 410.

[0137] In some embodiments, the main unit 21 further includes an air supply housing 430. The air supply housing 430 has a hollow structure. A piezoelectric ceramic sheet 410 is disposed in the inner cavity of the air supply housing 430 to drive the air in the inner cavity to form an airflow, which is beneficial to improving the airflow generation efficiency. Optionally, the air supply housing 430 is at least partially exposed to the air passage 303, so that the air output from the air supply housing 430 can directly enter the air passage 303, which is beneficial to improving the internal structural compactness of the main unit 21 and realizing the miniaturization of the main unit 21. In other embodiments, the air supply housing 430 may also be completely outside the air passage 303, for example, in another cavity connected to the air passage 303.

[0138] The air supply housing 430 can be disposed within the main unit housing 330, serving as a component connected to the main unit housing 330. In other embodiments, the air supply housing 430 can be a part of the main unit housing 330; in other words, a portion of the main unit housing 330 forms a cavity in which the piezoelectric ceramic sheet 410 is disposed. In other embodiments, the main unit 21 may not have an air supply housing 430, and instead, the piezoelectric ceramic sheet 410 may be disposed within the air passage 303.

[0139] The specific structure of the air supply housing 430 can be designed as needed. In this embodiment, the airflow path can be changed by adjusting the structure of the air supply housing 430.

[0140] In some embodiments, a first air outlet 431 is provided on one side of the air supply housing 430, and a first air inlet 432 is provided on the other side. Both the first air outlet 431 and the first air inlet 432 are connected to the inner cavity of the air supply housing 430, and the first air outlet 431 is connected to the air passage 303. The piezoelectric ceramic plate 410 is used to vibrate in the inner cavity of the air supply housing 430, so that air flows into the air supply housing 430 from the first air inlet 432, and then flows into the air passage 303 from the first air outlet 431 to form an airflow.

[0141] In this embodiment, the number of first air outlets 431 and first air inlets 432 is at least one. By placing the first air outlets 431 and first air inlets 432 on different sides of the air supply housing 430, for example, on opposite sides of the air supply housing 430, the air supply mechanism 400 can achieve air intake and exhaust from opposite sides. In this case, the air will form a relatively obvious flow path within the inner cavity of the air supply housing 430. The first air outlet 431 can be located on the side of the air supply housing 430 facing the air passage 303.

[0142] Optionally, the first air outlet 431 and the first air inlet 432 are respectively disposed on opposite sides of the air supply housing 430 along the thickness direction. There are multiple first air inlets 432 and at least one first air outlet 431. At least two first air inlets 432 are distributed along the width direction of the air supply housing 430 on both sides of the piezoelectric ceramic sheet 410 to form at least two airflow paths within the air supply housing 430. In other embodiments, the air supply housing 430 may also have only one airflow path.

[0143] In some embodiments, the first air inlet 432 may communicate with the air inlet 304 described above. In other embodiments, the first air inlet 432 may serve as the air inlet 304.

[0144] In this embodiment, the air supply housing 430 can also be designed with other structures. Please refer to the above text. Figures 19 to 21 , Figure 19 This is a schematic plan view of the air supply mechanism provided in some other embodiments of this application. Figure 20 yes Figure 19 A cross-sectional structural diagram of the air supply mechanism in the embodiment. Figure 21 yes Figure 19 An exploded view of the air supply mechanism in the embodiment.

[0145] The air supply mechanism 400 includes a piezoelectric ceramic sheet 410 and optionally a diaphragm 420, which has been described above and will not be repeated here.

[0146] The piezoelectric ceramic plate 410 can be disposed in the inner cavity of the air supply housing 430. A second air outlet 433 and a second air inlet 434 can be provided on one side of the air supply housing 430. Both the second air outlet 433 and the second air inlet 434 are connected to the inner cavity of the air supply housing 430 and to the air passage 303. The piezoelectric ceramic plate 410 is used to vibrate within the inner cavity of the air supply housing 430, causing air to flow into the air supply housing 430 from the second air inlet 434 and then into the air passage 303 from the second air outlet 433, thus forming an airflow.

[0147] Therefore, the air supply mechanism 400 can achieve air inlet and outlet on the same side. The second air outlet 433 and the second air inlet 434 can both be set on the side of the air supply housing 430 facing the air passage 303.

[0148] The main difference between the same-side air supply mechanism 400 and the opposite-side air supply mechanism 400 is that the same-side air supply mechanism 400 has its air inlet and outlet located on the same side of the air supply housing 430. Since the inlet and outlet are on the same side, the air flow around this air supply mechanism 400 is more complex than that of the opposite-side air supply mechanism 400. However, the principle of airflow generation is roughly the same for both, which is to generate a pressure difference through the vibration of the piezoelectric ceramic plate 410 to achieve air intake and exhaust, thus forming an air outlet effect.

[0149] Since the second air outlet 433 and the second air inlet 434 are located on the same side of the air supply housing 430, air in the air passage 303 can enter the air supply housing 430 from the second air inlet 434, and then be re-delivered to the air passage 303 from the second air outlet 433 by the push of the piezoelectric ceramic plate 410 and / or the diaphragm 420. At this time, the fragrance outlet 302 can also serve as the air inlet 304 (or it can be considered as not having an air inlet 304). In some other embodiments, another airflow channel can also be provided inside the main housing 330, which can be used to realize air intake and air exhaust respectively with the air passage 303.

[0150] In other embodiments, the host 21 may also use other air supply devices to replace the air supply mechanism 400 described above to achieve the air supply function. The air supply devices are, for example, but not limited to, axial flow fans, diaphragm pumps, etc.

[0151] It should be noted that in the embodiment where the air supply mechanism 400 is disposed in the aroma diffuser assembly 10, the housing 11 can be regarded as the aforementioned air supply shell 430, which is disposed in the aroma diffuser assembly 10. The aroma outlet 302 of the housing 11 can be regarded as the air outlet of the air supply shell 430 (e.g., the first air outlet 431, the second air outlet 433), and the air inlet 401 of the housing 11 can be regarded as the air inlet of the air supply shell 430 (e.g., the first air inlet 432, the second air inlet 434). A piezoelectric ceramic sheet 410 is disposed in the housing 11 and is used to generate vibration under the action of an electric field to output airflow to the evaporation section 120. The piezoelectric ceramic sheet 410 can be electrically connected to the drive mechanism 380 of the main unit 21.

[0152] It should be understood that the terminology used in this specification and appended claims is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. Similarly, the terms “first” and “second” in the description of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features. Furthermore, the term “multiple” in the description of this application means two or more, unless otherwise explicitly specified.

[0153] This application also provides another fragrance diffuser. Please refer to... Figure 22 , Figure 22 This is a schematic diagram of the structure of a diffuser provided in other embodiments of this application. Figure 22 The diffuser 30 shown is a device that further adds a sensing and adjustment function to the diffuser 20 described above. The diffuser 30 can include all the structures of the diffuser 20 described above, which will not be described in detail below.

[0154] In some embodiments, the aroma diffuser 30 includes a control board 370 and a sensing component 500. The control board 370 is electrically connected to both the piezoelectric ceramic sheet 410 and the sensing component 500. The sensing component 500 is used to acquire status information of the aroma diffuser 30, and the control board 370 is used to control the vibration frequency of the piezoelectric ceramic sheet 410 according to the status information, such as controlling the piezoelectric ceramic sheet 410 to stop vibrating, vibrate at a low frequency, or vibrate at a high frequency. The control board 370 and the sensing component 500 can be disposed on the main unit 21 or in other mechanisms, such as the aroma diffuser assembly 10.

[0155] The content of the state information acquired by the sensing component 500 can be selected as needed, and the specific structure of the sensing component 500 can also be designed accordingly. Optionally, the sensing component 500 includes an angle sensor 510 and an acceleration sensor 520. Both the angle sensor 510 and the acceleration sensor 520 are electrically connected to the control board 370. The control board 370 can use the state information acquired by the sensing component 500 to identify the arm's posture, and then, when the user swings the arm to different postures, control the vibration frequency of the piezoelectric ceramic plate 410 to switch to a preset value according to a preset scheme.

[0156] The angle sensor 510 acquires status information including angle information, corresponding to the current angle of the diffuser 30. When the arm wearing the diffuser 30 swings, the angle of the diffuser 30 may change accordingly, and the angle information acquired by the angle sensor 510 will change accordingly. The angle sensor 510 is used to detect angle changes, and its type is, for example, but not limited to, a photoelectric sensor, a magnetic sensor, etc. Its working principle is to calculate the angle by measuring the change of electrical signal generated by the internal components of the sensor (such as grating elements, magnetic elements) as the arm rotates.

[0157] The accelerometer 520 acquires state information including acceleration information, corresponding to the current acceleration of the diffuser 30. When the arm wearing the diffuser 30 swings, the acceleration of the diffuser 30 may change accordingly, and the acceleration information acquired by the accelerometer 520 will change accordingly. The accelerometer 520 is used to detect changes in acceleration, and its type is, for example, but not limited to, a piezoresistive sensor, a piezoelectric sensor, a capacitive sensor, etc.

[0158] When the arm moves, the accelerometer 520 detects changes in acceleration. These changes are converted into electrical signals, and algorithms are used to extract feature information related to arm posture, such as stride frequency and stride length. For example, when the arm swings, the accelerometer 520 captures the periodic changes in acceleration, thereby determining the arm's movement state and posture.

[0159] In other embodiments, the sensing component 500 may include only one of the angle sensor 510 and the acceleration sensor 520 for acquiring angle information or acceleration information. In other embodiments, the sensing component 500 may also be designed with other structures to acquire other state information, so that the control board 370 can control the vibration frequency of the piezoelectric ceramic sheet 410 according to the other state information. For example, the sensing component 500 may include a temperature sensor, and the state information that can be acquired is temperature information.

[0160] Please see Figure 23 and Figure 24 , Figure 23This is a three-dimensional structural schematic diagram of the aroma diffuser provided in some embodiments of this application. Figure 24 yes Figure 23 A schematic diagram of the planar structure of the aroma diffuser in the embodiment.

[0161] In some embodiments, the aroma diffuser 30 may include a wearing part 31 connected to the aroma diffuser assembly 10 for wearing on the human body. The wearing part 31 may be directly connected to the aroma diffuser assembly 10 or indirectly connected to it. For example, the wearing part 31 may be disposed on the main unit 21 and indirectly connected to the aroma diffuser assembly 10 through the main unit 21; the wearing part 31 may be connected to the main unit 21 or integrally formed with the main unit 21.

[0162] The shape of the wearing part 31 can be set as needed; for example, the wearing part 31 can be designed as follows: Figure 23 The device is shaped like a bracelet and is worn on the wrist. The diffuser 30 can be worn on the body via the wearing part 31, thereby improving the air quality around the body in real time.

[0163] It should be noted that the aroma diffuser 30 can be worn on the arm, neck, or other parts of the body, or it can be worn on clothing or other personal items. Please refer to [link / reference]. Figure 25 and Figure 26 , Figure 25 This is a three-dimensional structural schematic diagram of the aroma diffuser provided in some other embodiments of this application. Figure 26 yes Figure 25 A schematic diagram illustrating the application scenario of the aroma diffuser in the embodiment.

[0164] In other embodiments, the wearing part 31 can be a magnetic element, and is magnetically attracted to another mechanism of the diffuser 30 in a separable manner. The magnetic element can be designed as a ring, for example... Figure 25 The magnetic element is shown as a ring shape. In other embodiments, the magnetic element can also be designed in other shapes, such as a block shape. Taking the magnetic attraction between the magnetic element and the main unit 21 as an example, when wearing the device, the user can first remove the magnetic element and then fix the clothing as a layer between the magnetic element and the main unit 21. The diffuser 30 is fixed to the clothing by using the magnetic attraction between the magnetic element and the main unit 21.

[0165] The following description primarily uses the example of the aroma diffuser 30 being worn on the arm of a person. In other embodiments, the aroma diffuser 30 may not have a wearing part 31. In this case, the aroma diffuser 30 can be used by the user by hand or placed on other structural components such as a gripping rod. The following description primarily uses the example of the aroma diffuser 30 including the wearing part 31.

[0166] Please see Figure 27 , Figure 27 This is a schematic flowchart of a control method for a fragrance diffuser provided in some embodiments of this application. This control method can be applied to the aforementioned fragrance diffuser 30.

[0167] The control methods for aroma diffusers include:

[0168] S1: Get status information.

[0169] The status information is acquired by the sensing component 500 of the aroma diffuser 30, and the status information may include, but is not limited to, angle information, acceleration information, etc.

[0170] S2: Identify current human actions based on state information.

[0171] Understandably, when the part of the body wearing the aroma diffuser 30 moves, the state information will change accordingly. Therefore, the control panel 370 of the aroma diffuser 30 can identify the current human posture based on the state information.

[0172] S3: Control the vibration frequency of the piezoelectric ceramic sheet according to the preset scheme corresponding to human body movements.

[0173] The aroma diffuser 30 can store one or more preset schemes, each corresponding to a preset human action. For example, one preset scheme corresponds to the action of raising an arm; when the aroma diffuser 30 detects that the user's arm is raised, it can automatically control the piezoelectric ceramic plate 410 to start vibrating and activate the airflow function. Another preset scheme corresponds to the action of lowering an arm; when the aroma diffuser 30 detects that the user's arm is lowered, it can automatically control the piezoelectric ceramic plate 410 to vibrate and stop according to a preset ratio, such as vibrating for 1 minute, stopping for 1 minute, and repeating this cycle. Understandably, the preset schemes stored in the aroma diffuser 30 are, but not limited to, the two mentioned above.

[0174] It should be noted that the actions that the diffuser 30 can recognize are not limited to arm swinging movements. Please refer to [link / reference]. Figure 28 and Figure 29 , Figure 28 These are schematic diagrams illustrating application scenarios of the aroma diffuser provided in some embodiments of this application. Figure 29 yes Figure 28 A schematic diagram of the application scenario of the aroma diffuser in another state in the embodiment.

[0175] Optionally, the aroma diffuser 30 can utilize the sensing component 500 to recognize tapping actions. When the tapping action taken by the user matches a preset human motion in the aroma diffuser 30, the aroma diffuser 30 can recognize the tapping action based on the acquired state information, and then control the vibration frequency of the piezoelectric ceramic sheet 410 accordingly. The state information corresponding to the preset tapping action may be, for example, acceleration information, or may include both acceleration and angular velocity information.

[0176] For example, when the diffuser 30 is powered on and detects two consecutive taps, it will switch to the power-off state and control the piezoelectric ceramic plate 410 to stop vibrating; when the diffuser 30 is powered off and detects two consecutive taps, it will switch to the power-on state and control the piezoelectric ceramic plate 410 to start vibrating. Of course, this is only an exemplary scenario, and the human body movements that the diffuser 30 can recognize and the preset solutions that can be adopted are not limited to this.

[0177] Furthermore, the control method of the diffuser 30 provided in this application embodiment is not limited to the above method. For example, in other embodiments, the diffuser 30 can also control the vibration efficiency of the piezoelectric ceramic sheet 410 according to the recognized human body movements. For example, according to the number of times the wrist rotates within a preset time, the piezoelectric ceramic sheet 410 is controlled to switch between multiple vibration frequencies, so that the diffuser 30 switches between multiple states with different fragrance output efficiencies.

[0178] For details not covered in this control method, please refer to the description of the diffuser 30 above.
