Description

Technical Field

[0001] This utility model belongs to the field of household aromatherapy technology, and specifically relates to an aromatherapy device. Background Technology

[0002] Aromatherapy is a product used in indoor environments to improve the smell of the air. With the improvement of living standards, more and more people are accepting and using aromatherapy products. In order to improve the indoor air environment, people usually place solid air fresheners, spray perfumes, or place aromatherapy essential oils indoors to make the space fragrant, eliminate the user's fatigue, and enliven the atmosphere of the space. Coupled with soft music, the fresh and sweet floral fragrance can be smelled in the nose, seeping into the bone, with a subtle fragrance floating in the air, enhancing the enjoyment.

[0003] However, existing aromatherapy devices that use diffuser sheets for fragrance diffusion have complex structures. Once the diffuser sheets lose their fragrance, they need to be replaced frequently or perfume needs to be added to them. Replacing the diffuser sheets or adding perfume requires disassembling the entire aromatherapy device, making the whole process complicated and cumbersome. Using absorbent cotton wicks to absorb perfume for diffusion can easily cause leakage and spillage problems, and the overall appearance is also relatively simple.

[0004] To address the aforementioned issues, existing technologies employ a combination of a perfume pouch and a breathable membrane to achieve fragrance dispersal, as illustrated in the previously disclosed patent "CN201080017262.9". This patent integrates a sealing aluminum foil inside the perfume pouch and places a piercing element between the breathable membrane and the aluminum foil to allow the perfume to flow out and disperse. In this method, the perfume pouch integrates aluminum foil, a piercing element, and a breathable membrane, resulting in a complex overall structure, difficult manufacturing processes, and the risk of accidental puncture of the aluminum foil during production and assembly due to the direct contact between the piercing element and the aluminum foil. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing technical defects and provide an aromatherapy device with good fragrance diffusion effect, long fragrance retention time and good leakage prevention effect. The overall structure is simple and easy to process and assemble, and the ruptureable sealing sheet will not be accidentally punctured during the assembly process.

[0006] To address the aforementioned technical problems, this utility model provides an aromatherapy device, comprising a housing with a cavity and a perfume container disposed within the housing for containing fragrance substances. The housing has several ventilation holes at its rear end and / or around its perimeter.

The rear end of the perfume container also has a vaporization film located outside the ruptureable sealing sheet. Inside the rear end of the housing, there is an elastic puncture member that moves inward and compresses the vaporization film and the ruptureable sealing sheet when subjected to force. The front end of the elastic puncture member has at least one protrusion facing the vaporization film, with the end of the protrusion closest to the vaporization film being non-sharp. The rear end of the elastic puncture member extends outward beyond the rear end of the housing.

[0007] Furthermore, the housing includes a front shell and a rear shell that are interlocked. The bottom of the rear shell is flat. The perfume container is inclinedly disposed in the cavity formed between the front shell and the rear shell, and the front shell is inclinedly disposed on the rear shell.

[0008] Furthermore, the container is provided with a receiving groove for containing the fragrance substance, and a ring platform is provided on the outer periphery of the rear end of the container. The ruptureable sealing sheet and the volatile film are both connected to the outer end face of the ring platform to seal the receiving groove. The outer diameter of the ruptureable sealing sheet is smaller than the outer diameter of the ring platform, and the outer diameter of the volatile film is the same as the outer diameter of the ring platform.

[0009] Furthermore, the inner protrusion of the front shell is provided with a limiting ring that surrounds the perfume container and abuts against the ring platform, and the inner protrusion of the rear shell is provided with a plurality of supporting ribs that abut against the ring platform, thereby clamping the perfume container from front to back.

[0010] Furthermore, both the perfume container and the front shell are made of translucent or transparent materials.

[0011] Furthermore, the elastic puncture member includes a pressing part that passes through the rear shell, connecting arms located on the upper and lower sides of the pressing part, and two elastic arms that apply a rebound force to the connecting arms. The rear shell has a circular hole through which the pressing part passes. The rear end of the pressing part protrudes out of the rear shell. One end of the elastic arm is connected to the inner side of the rear shell. The front ends of the two connecting arms each have a protrusion facing the volatile film, and the two protrusions correspond to the upper and lower ends of the receiving groove, respectively.

[0012] Furthermore, the elastic arm is U-shaped, and its two ends are respectively connected to the same side of the upper and lower connecting arms. The two elastic arms are symmetrically arranged on both sides of the two connecting arms. A fixing hole is provided in the middle of the outer end of the elastic arm, and a hot-melt column that is inserted into the fixing hole is provided on the inner side of the rear shell.

[0013] Furthermore, the inner side of the rear shell has a protrusion with a limiting ring surrounding the pressing part, the limiting ring has a limiting groove, the outer periphery of the pressing part has a protrusion with a limiting rib that slides in the limiting groove, and the limiting ring has a sliding groove for the connecting arm to pass through and slide back and forth.

[0016] This utility model has the following beneficial effects:

[0017] This invention utilizes a perfume container holding fragrant substances as the main body for fragrance dispersing, avoiding the need for continuous refilling or replacement of perfume diffusers when using diffuser sheets. This reduces the need to disassemble the casing, resulting in a simpler overall structure. Furthermore, a ruptureable sealing strip at the opening of the perfume container allows for sealing before opening, preventing perfume waste due to evaporation. During use, pressing the elastic puncture member causes it to move inward, compressing the evaporation film and the ruptureable sealing strip. The ends of the puncture members are designed to be non-sharp, preventing... The device directly punctures the evaporation membrane and the ruptureable seal, causing them to deform under pressure. During this deformation, the ruptureable seal breaks at the point of compression, while the evaporation membrane remains intact. This allows the perfume inside the container to flow out through the break in the ruptured seal and be absorbed by the evaporation membrane, then slowly evaporate and diffuse. This results in a long-lasting fragrance without wasting perfume, offering excellent fragrance diffusion and leak-proof performance. The elastic puncture element is located on the inner rear end of the housing and outside the perfume container, resulting in a simple overall structure, easy processing and assembly, and preventing accidental puncture of the ruptureable seal during assembly.

[0018] Secondly, both the perfume container and the front shell are made of semi-transparent or transparent materials, allowing the fragrance substances inside the perfume container to be observed through the front shell, thus improving the aesthetic appeal and structural novelty.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and 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] Example

[0038] like Figures 1 to 14 As shown in the figure, the aromatherapy device in this embodiment includes a shell with a cavity 10 and a perfume container 2 disposed within the shell for containing fragrance substances. The shell includes a front shell 1 and a rear shell 3 connected front to back, with a cavity 10 formed between the front shell 1 and the rear shell 3 to contain the perfume container 2. The rear shell 3 has a plurality of ventilation holes 31 extending through its rear end and / or all around to allow airflow inside and outside the shell and to diffuse fragrance outward. The rear end of the perfume container 2 is an opening, and the opening is provided with a ruptureable seal made of an impermeable liquid material for sealing. The rear end of the perfume container 2 is also provided with a volatile film 22 located outside the ruptureable sealing sheet 21. The ruptureable sealing sheet 21 and the volatile film 22 are arranged adjacent to each other and closely attached. The thickness of the ruptureable sealing sheet 21 is less than the thickness of the volatile film 22, so that the ruptureable sealing sheet 21 is configured to rupture with less elongation than the volatile film 22 when an external force is applied to the volatile film 22 from the outside in the thickness direction. The inner side of the rear shell is provided with an elastic puncture member 4 (e.g., after being subjected to force, it moves inward and squeezes the volatile film 22 and the ruptureable sealing sheet 21). Figure 3 As shown), the rear end of the elastic puncture member 4 extends outward into the rear shell 3, allowing the user to manually press the elastic puncture member 4 to move it inward and compress the evaporation film and the ruptureable seal. The front end of the elastic puncture member 4 is provided with at least one protrusion 41 facing the evaporation film 22. The end of the protrusion 41 closest to the evaporation film 22 is non-sharp, so it will not directly puncture the evaporation film and the ruptureable seal. This avoids the protrusion 41 directly piercing the ruptureable seal 21 and the evaporation film 22, but only causing the evaporation film and the ruptureable seal to deform under pressure. During the compression deformation process, the ruptureable seal ruptures at the compressed point, while the evaporation film does not rupture (e.g., Figure 6 and Figure 7(As shown), the perfume inside the container flows out through the rupture of the ruptured seal and is absorbed by the evaporation film, then slowly evaporates and diffuses, resulting in a long-lasting fragrance without wasting perfume. It features excellent fragrance diffusion and leak-proof performance. The elastic puncture element is located inside the rear shell and outside the perfume container, resulting in a simple overall structure, easy processing and assembly, and preventing accidental puncture of the ruptured seal during assembly.

[0039] In one embodiment, in the assembled state when not in use, the end of the protrusion 41 abuts against the evaporation membrane 22 to press the perfume container forward and prevent the perfume container from becoming loose.

[0040] In another embodiment, in the assembled state when not in use, the end of the spike can also be a certain distance away from the evaporation membrane, such as 1-2 mm, to avoid excessive pressure on the evaporation membrane and the ruptureable seal due to assembly or processing errors when not in use.

[0041] Optionally, the ruptureable sealing sheet 21 is preferably made of aluminum foil, and its thickness is preferably 5-25 μm, so that it can be easily broken when subjected to the pressure of a puncture.

[0042] Optionally, the evaporation membrane 22 is preferably a porous membrane, i.e. a dialysis membrane, from brands such as Teslin and Daramic. It has the characteristics of good flexibility and slow evaporation after liquid absorption without overflow. The thickness of the evaporation membrane 22 is preferably 0.5-1 mm.

[0043] In one embodiment, such as Figure 3 As shown, both the perfume container 2 and the front shell 1 are made of translucent or transparent materials, so that the perfume container inside can be seen directly through the front shell 1. Combined with the perfume container made of transparent or translucent materials, the perfume inside can be seen directly through the perfume container. In practical applications, fluorescent powder or other additives can be added to the perfume to make the perfume inside more beautiful and highly ornamental.

[0044] In one embodiment, such as Figures 1 to 3 As shown, the bottom of the rear shell 3 is a flat surface 30, which allows the aromatherapy device to be placed vertically using the flat surface at the bottom of the rear shell 3. The perfume container 2 is inclined upward and placed in the cavity 10 formed between the front shell 1 and the rear shell 3. The front shell 1 is inclined upward and placed on the rear shell 3, and the perfume container 2 and the front shell 1 have the same inclination, so that the user can easily observe the perfume container inside.

[0045] In one embodiment, such as Figures 1 to 10As shown, the perfume container 2 has a receiving groove 23 for holding the fragrance substance. A ring platform 24 is radially protruding from the outer periphery of the rear end of the perfume container 2. A limiting ring 11 is provided on the inner side of the front shell 1, surrounding the perfume container 2 and abutting against one side of the ring platform 24. A plurality of supporting ribs 32 are provided on the inner side of the rear shell 3, abutting against the other side of the ring platform 24. These components clamp the perfume container 2 from front to back, achieving front-to-back positioning of the perfume container. The ruptureable sealing sheet 21 and the evaporation film 22 are both connected to the ring platform 24. The outer end face of the platform 24 is heat-sealed to seal the receiving groove 23. The outer diameter of the ruptureable sealing sheet 21 is smaller than the outer diameter of the platform 24, and the outer diameter of the evaporation film 22 is the same as the outer diameter of the platform 24. That is, the inner circumference of the end face of the platform 24 is heat-sealed to the ruptureable sealing sheet 21, and the outer circumference is heat-sealed to the evaporation film 22. In actual production, after perfume is put into the receiving groove of the perfume container 2, the ruptureable sealing sheet 21 is heat-sealed on the platform first, and then the evaporation film 22 is heat-sealed.

[0046] In another embodiment, the temperature for heat-sealing the ruptureable sealing sheet 21 is 135-140 degrees Celsius, and the temperature for heat-sealing the volatile film 22 is 130-135 degrees Celsius. At these heat-sealing temperatures, the ruptureable sealing sheet and the volatile film can be firmly heat-sealed to the ring platform, and the connection between the outer periphery of the ruptureable sealing sheet and the volatile film and the ring platform will not break or fall off when subjected to the compressive force of the puncture.

[0047] In one embodiment, such as Figures 3 to 14 As shown, the elastic puncture member 4 includes a pressing part 42 that passes through the rear shell 3, connecting arms 43 located on the upper and lower sides of the pressing part 42, and two elastic arms 44 that apply a rebound force to the connecting arms 43. The rear shell 3 has a circular hole 33 through which the pressing part 42 passes, so that the rear end of the pressing part 42 protrudes out of the rear shell 3. One end of the elastic arm 44 is connected to the inner side of the rear shell 3. The front end of each of the two connecting arms 43 is provided with a protrusion 41 facing the evaporation film 22, and the two protrusions 41 are respectively connected to the receiving groove 2. The upper and lower ends of 3 correspond, that is, the two protrusions 41 are on the same vertical plane. When the aromatherapy device is placed vertically through the plane at the bottom of the rear shell, the rupture openings of the ruptureable sealing sheet after being pressed are located at the upper and lower ends of the perfume container, so that the perfume inside can continuously flow out from the rupture openings under the action of gravity and be absorbed by the evaporation membrane. After absorbing the perfume, the evaporation membrane will disperse the perfume to the entire evaporation membrane through the micropores distributed inside it, so that the perfume will not accumulate at the absorption port at the lower end of the evaporation membrane.

[0048] In one embodiment, such as Figures 5 to 14As shown, the elastic arm 44 is U-shaped, with its two ends connected to the same side of the upper and lower connecting arms 43 respectively. The two elastic arms 44 are symmetrically arranged on both sides of the two connecting arms 43, forming a cross shape with the line connecting the two elastic arms 44 and the line connecting the two connecting arms 43. A fixing hole 45 is provided in the middle of the outer end of the elastic arm 44, and a hot-melt column 34 is provided on the inner side of the rear shell 3 to be inserted into the fixing hole 45. During assembly, after the hot-melt column 34 passes through the fixing hole 45, the hot-melt column is hot-melted to make the two connected and fixed and inseparable, avoiding the problem of the elastic puncture part falling off. In this structure, when the elastic puncture part moves inward under pressure, one end of the elastic arm 44 will... As the pressing part 42 and the connecting arm 43 move inward synchronously, the other end of the elastic arm 44 is connected to the rear shell 3 and cannot move. Therefore, when the external force applied to the pressing part 42 is removed, the deformed elastic arm 44 will exert a rebound force on the pressing part 42 and the connecting arm 43 to return to their original position. During the assembly of this aromatherapy device, as long as the pressing part is not pressed in such a way that its inward movement exceeds the stroke of the ruptureable seal, the ruptureable seal will not be accidentally punctured during the assembly process. A small amount of pressure is not enough to puncture or break the ruptureable seal. Therefore, the problem of the ruptureable seal being accidentally punctured during the assembly process is an extremely low probability event.

[0049] In one embodiment, such as Figures 5 to 14 As shown, the inner side of the rear shell 3 has a protruding limiting ring 35 surrounding the circular hole 33 and the pressing part 42. The limiting ring 35 has a limiting groove 351. The outer periphery of the pressing part 42 has a protruding limiting rib 46 that slides in the limiting groove 351, so that the elastic piercing part 4 can only move back and forth within the range of the limiting groove 351, avoiding the elastic piercing part 4 from exceeding the elastic stroke of the elastic arm and causing damage and failure of the elastic arm; and the upper and lower sides of the limiting ring 35 have sliding grooves 352 for the connecting arm 43 to pass through and slide back and forth.

[0050] In one embodiment, such as Figures 5 to 14 As shown, the limiting ring 35 is provided with an opening 353 on the other side of the corresponding limiting groove 351. The opening 353 is provided with an elastic piece 354 arranged along the axial direction of the limiting ring 35 in the middle. The inner side of the elastic piece 354 is provided with a positioning rib 355. The outer periphery of the pressing part 42 is provided with a rib 47 that cooperates with the positioning rib 355. When the rib 47 passes through the positioning rib 355, it will apply an outward elastic deformation pressure to the positioning rib 355 and the elastic piece 354. After the rib 47 passes forward through the positioning rib 355, the elastic piece 354 returns to its original shape under the elastic action. During this process, the aromatherapy device will make a clicking sound to indicate to the user that it has been pressed inward to the correct position. At this time, the pressure applied to the pressing part can be removed. Specifically, the projections of the positioning rib 355 and the rib 47 on the circumferential plane of the outer periphery of the pressing part have overlapping parts.

[0051] In one specific implementation, the perfume container and casing are preferably circular in structure.

[0052] In other embodiments, the end of the spike closest to the evaporation film is planar or spherical, and the area of ​​the end of the spike closest to the evaporation film is 10-12 mm². 2 This ensures that the contact area between the spikes and the volatile film is controlled at 10-12 mm. 2 This avoids the problem of excessive contact area causing the sealant or volatile film to break after squeezing, resulting in damage.

[0053] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
