Description

Technical Field

[0001] This utility model belongs to the field of household or car fragrance technology, specifically relating to a vent fragrance diffuser. Background Technology

[0002] Aromatherapy products are used in indoor or car 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, the existing diffuser diffusers that use diffuser sheets for fragrance diffusion have a complex structure. After 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 diffuser, which is a complicated and cumbersome process. Using absorbent cotton cores to absorb perfume for diffusion can easily cause leakage and spillage, and the overall appearance is also relatively simple.

[0004] To address the aforementioned issues, existing structures utilize a perfume pouch and a breathable membrane to achieve fragrance dispersal, as shown in the previously disclosed patent "CN201080017262.9". This design integrates a sealing aluminum foil inside the perfume pouch and a piercing element between the breathable membrane and the aluminum foil to allow the perfume to flow out and disperse. However, this method integrates the aluminum foil, piercing element, and breathable membrane into the perfume pouch, resulting in a complex overall structure and difficult manufacturing processes. Furthermore, the piercing element directly contacts the aluminum foil, increasing the risk of accidental puncture during assembly. Additionally, this structure uses a cam on a clamp to compress the volatile composition container when it rotates to a horizontal position, thus breaking the internal aluminum foil. However, this structure constantly applies pressure to the volatile composition container, causing the piercing element to remain inserted in the rupture opening and hindering liquid outflow. Additionally, prolonged compression and deformation of the outer membrane can lead to toughness failure and rupture. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing technical defects and provide a vent-type aromatherapy diffuser 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 a diffuser with an air vent, 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 perfume container has an open rear end, with a ruptureable sealing sheet made of a liquid-impermeable material at the opening for sealing. 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. At the center of the rear end of the housing, there is an elastic drive member that rotates inward and pushes the elastic puncture member inward when subjected to force. A clamp is rotatably provided at the rear end of the housing to push the elastic drive member inward.

[0007] Furthermore, the clamp is capable of rotating back and forth between a horizontal and a vertical position relative to the housing. During the process of rotating from the vertical position to the horizontal position, the clamp pushes the elastic drive member to rotate inward, and during the process of rotating from the horizontal position to the vertical position, the clamp drives the elastic drive member to rotate outward.

[0008] Furthermore, the clamp has a protruding drive part at one end near the elastic drive member, which pushes or drives the elastic drive member to rotate, and an insertion port for accommodating the drive part is formed between the lower end of the elastic drive member and the housing.

[0009] Furthermore, the housing includes a front shell and a rear shell that are interlocked, the elastic puncture member is disposed on the inner side of the rear shell, the rear end of the rear shell is provided with a plurality of ventilation holes, the elastic drive member is integrally formed in the middle of the rear shell, and the clamp is rotatably disposed on the outer side of the rear shell.

[0010] Furthermore, the rear shell has an opening in the middle, the elastic drive member is disposed in the opening, and both sides of the upper end of the elastic drive member are connected to the rear shell through elastic rotating arms. An insertion port for accommodating the drive part is formed between the lower end of the elastic drive member and the rear shell.

[0011] 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.

[0012] Furthermore, the front shell has a through hole for the front end of the perfume container to pass through, and the perfume container is made of a semi-transparent or transparent material; the inner side of the front shell has a protruding limiting ring that surrounds the perfume container and abuts against the ring platform, and the inner side of the rear shell has a protruding supporting rib that abuts against the ring platform, clamping the perfume container from front to back.

[0013] Furthermore, the elastic puncture component includes a movable plate disposed on the inner side of the rear shell and two elastic arms symmetrically disposed on both sides of the movable plate and applying a rebound force to the movable plate. The upper and lower ends of the movable plate are each provided with a protrusion facing the receiving groove. The elastic arms are C-shaped, and the two ends of the elastic arms are respectively connected to the upper and lower ends of one side of the movable plate. The outer end of the elastic arm is provided with a fixing hole in the middle, and the inner side of the rear shell is provided with a hot-melt column that is inserted into the fixing hole.

[0014] Furthermore, the lower end of the receiving groove is recessed to form a liquid guiding groove, and the protrusions at the lower end of the moving plate are positioned toward the liquid guiding groove.

[0015] Furthermore, a cotton pad is embedded on the inner side of the lower end of the rear shell to abut against the volatile membrane; the end of the protrusion closest to the volatile membrane is flat or spherical; the ruptureable sealing sheet is aluminum foil, and the volatile membrane is a dialysis membrane.

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

[0017] This utility model's air vent diffuser utilizes a perfume container holding the fragrance-emitting substance as the main body for fragrance dispersal, avoiding the need for continuous perfume addition or replacement of the perfume dispersing tablets after they have absorbed the fragrance. This reduces the process of disassembling the casing, resulting in a simple overall structure. Furthermore, a ruptureable sealing strip is provided at the opening of the perfume container. Before use, the container can be sealed to prevent perfume waste due to evaporation. During use, rotating the clamp drives the elastic drive component, which in turn pushes the elastic piercing component inward, causing the piercing to compress the evaporation film and the ruptureable sealing strip. The end of the diffuser is designed to be non-sharp, so it will not directly puncture the evaporation film and the ruptureable seal. Instead, it will cause the evaporation film and the ruptureable seal to deform under pressure. During the deformation process, the ruptureable seal will break at the point of compression, while the evaporation film will not break. This allows the perfume in the container to flow out from the break in the ruptureable seal and be absorbed by the evaporation film, and then slowly evaporate and diffuse. This makes the fragrance last longer without wasting perfume, and it has the characteristics of good fragrance diffusion and good leakage prevention. The elastic puncture element is located on the inner side of the rear end of the shell and outside the perfume container. The overall structure is simple, easy to process and assemble, and the ruptureable seal will not be accidentally punctured during assembly.

[0018] Secondly, the perfume container is made of a semi-transparent or transparent material, and the perfume container protrudes from the front shell, so that the fragrance substances inside the perfume container can be directly observed, which improves the appearance 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] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0037] 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.

[0038] Example

[0039] like Figures 1 to 15 As shown in the figure, the vent diffuser of 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 13 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). Figures 3 to 6As shown), 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 near 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 causes the evaporation film and the ruptureable seal to deform under pressure. During the compression deformation process, the ruptureable seal breaks at the compressed point, while the evaporation film does not break (e.g., Figure 6 As shown), the perfume inside the container flows out from the crack in 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 good fragrance diffusion and leak-proof properties. The rear end of the housing is equipped with an elastic drive element 5 (as shown) that can rotate inwards under pressure and push the elastic puncture element 4 inwards. Figure 5 and Figure 6 As shown), after the pressure is lost, the elastic drive 5 returns to its original position under the action of elastic force (as shown). Figure 7 As shown), the elastic puncture component 4 returns to its original position under the action of elastic force. The rear end of the rear shell 3 is also provided with a clamp 6 for pushing the elastic drive component 5 to rotate inward. That is, the purpose of puncturing the inner ruptureable sealing sheet 21 is achieved by rotating and changing the state of the clamp. The elastic puncture component is located inside the rear shell and outside the perfume container. The overall structure is simple, the processing and assembly are convenient, and the ruptureable sealing sheet will not be accidentally punctured during the production and assembly process.

[0040] 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.

[0041] 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 the spike exerting pressure on the evaporation membrane and the ruptureable seal when not in use due to assembly or processing errors.

[0042] 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.

[0043] 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.

[0044] In one embodiment, such as Figures 1 to 8As shown, the front shell 1 has a through hole 12 through which the front end of the perfume container 2 passes. The perfume container 2 is made of a semi-transparent or transparent material, so that 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.

[0045] In one embodiment, such as Figures 1 to 10 As 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 protruding from 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 35 are protruding from 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 12 As shown, the elastic puncture component 4 includes a movable plate 42 disposed inside the rear shell 3 and two elastic arms 43 symmetrically disposed on both sides of the movable plate 42 and applying a rebound force to the movable plate 42. Each of the upper and lower ends of the movable plate 42 is provided with a protrusion 41 facing the receiving groove 23, so that the rupture opening of the ruptureable sealing sheet 21 after being compressed is located at the upper and lower ends of the perfume container, respectively. This allows the perfume inside to continuously flow out from the rupture opening under the action of gravity and be absorbed by the evaporation membrane 22. After absorbing the perfume, the evaporation membrane 22 disperses the perfume throughout the evaporation membrane 22 through its internally distributed micropores, preventing the perfume from accumulating at the absorption opening at the lower end of the evaporation membrane.

[0048] In one embodiment, such as Figures 11 to 12As shown, the elastic arm 43 is C-shaped, with its two ends connected to the upper and lower ends of the same side of the movable plate 42, respectively. A fixing hole 44 is provided in the middle of the outer end of the elastic arm 43, and a hot-melt column 36, which is inserted into the fixing hole 44, is provided on the inner side of the rear shell 3. During assembly, after the hot-melt column 36 passes through the fixing hole 44, it is hot-melted to make the two connected and fixed, preventing the elastic puncture part from falling off. In this structure, when the elastic puncture part is pressed inward, one end of the elastic arm 43 moves inward synchronously with the movable plate 42, but the other end of the elastic arm 43 is connected to the rear shell 3 and cannot move. Therefore, when the external force applied to the movable plate 42 is removed, the deformed elastic arm 43 will exert a restoring force on the movable plate 42 to its original position. During the assembly of this air vent aromatherapy device, as long as the clamp is not rotated, a small amount of squeezing force is insufficient to puncture and break the ruptureable sealing sheet. Therefore, the problem of accidental puncture of the ruptureable sealing sheet during assembly is an extremely low probability event.

[0049] In one embodiment, such as Figures 4 to 6 As shown, the lower end of the receiving tank 23 is recessed to form a liquid guiding groove 25, and the protrusion 41 at the lower end of the moving plate 42 is set toward the liquid guiding groove 25, so that the perfume in the perfume container flows downward into the liquid guiding groove 25 and then flows out from the rupture, thereby making the most of the perfume inside and avoiding waste.

[0050] In one embodiment, such as Figures 2 to 15 As shown, the clip 6 has a protruding drive part 61 on the rotating end near the elastic drive member 5, which pushes or drives the elastic drive member 5 to rotate. An insertion port 50 for accommodating the drive part 5 is formed between the lower end of the elastic drive member 5 and the rear shell 3. The clip 6 can rotate back and forth between a horizontal position and a vertical position relative to the rear shell 3. The initial position at the time of manufacture is the vertical position for storage (i.e., the vertical position, such as...). Figure 3 As shown), the drive unit 61 is located at the upper end of the clamp. When it needs to be clamped onto a car seal, the clamp is rotated upwards to open it and rotate it to a horizontal position (i.e., a horizontal position, as shown). Figure 7(As shown); During the process of clamp 6 rotating from the vertical position to the horizontal position, the driving part 61 rotates downward to contact the outer side of the elastic driving member 5 and applies pressure to the elastic driving member 5 to push the elastic driving member 5 to rotate inward. When clamp 6 rotates to the horizontal state, the driving part 61 disengages from the elastic driving member 5 and inserts into the insertion port 50. At this time, the driving part 61 cannot apply pressure to the elastic driving member 5, so that the elastic driving member 5 and the elastic piercing member 4 return to their original positions under the action of elasticity. The maximum stroke of the elastic piercing member 4 moving inward can be limited by the driving method of the elastic driving member 5. In this way, the aluminum foil can be pierced at this stroke while avoiding the evaporation film being pierced due to excessive pressure. Under this stroke, the compression stroke of the piercing member on the evaporation film and the green foil is generally controlled to be 2.5mm. During the process of clamp 6 rotating from the horizontal position to the vertical position, the driving part 61 rotates upward and drives the elastic driving member 5 to rotate outward. After rotating to a certain angle, the driving part 61 disengages from the elastic driving member 5, so that the elastic driving member 5 returns to its original position again.

[0051] In one embodiment, the elastic drive member 5 is integrally formed in the middle of the rear shell 3; specifically, the middle of the rear shell 3 is provided with an opening 30, the elastic drive member 5 is disposed in the opening 30, and both sides of the upper end of the elastic drive member 5 are integrally connected to the rear shell 3 through elastic rotating arms 51.

[0052] In one embodiment, the inner side of the drive part 61 is a slope, which facilitates the separation of the drive part from the elastic drive member after interference, and allows for better insertion into the insertion port.

[0053] In another embodiment, such as Figure 14 and Figure 15 As shown, the rotating connection structure between the clip 6 and the rear shell 3 is as follows: Two symmetrically spaced fixing parts 31 are provided on the outer side of the rear shell 3, spaced apart on both sides of the opening 30, and a locking part 32 is located above the opening 30. Each fixing part 31 has a fixing groove 33 on its inner side. One end of the clip 6 has a rotating part 62, and a driving part 61 is located on the outer end face of the rotating part. One end of the rotating part 62 has two rotating shafts 63 on both sides that are respectively inserted into the fixing grooves 33 of the two fixing parts 31, allowing the clip 6 to rotate 90 degrees relative to the rear shell 3, that is, allowing the clip 6 to be in a horizontal and vertical position. The clip can be changed between horizontal and vertical states. The other end of the rotating part 62 engages with the locking part 32 after rotating to the horizontal state. The engagement of the locking part 32 ensures the stability of the clip during use and prevents the clip from rotating randomly and affecting the position of the air vent diffuser. In the above, the clip 6 and the back shell 3 are connected by rotation to achieve the folding of the clip, reducing its space occupation and making it convenient to carry. In addition, the clip can also be engaged with the back shell after rotation to keep its position fixed after rotation. This allows the clip to be changed freely between the horizontal use state and the vertical folding state as needed.

[0054] As a preferred option, such as Figure 14 and Figure 15 As shown, the inner center of the fixing part 31 is provided with a clearance notch 34 for the rotating shaft 63 to be inserted into the fixing groove 33. After the clamp is rotated and folded, the rotating part 62 moves towards the center of the fixing groove 33, thereby allowing the rotating shaft 63 to slide out through the clearance notch 34, thus realizing the assembly and disassembly between the clamp and the fixing part.

[0055] In another embodiment, such as Figure 3 As shown, a cotton pad 37 is embedded on the inner side of the lower end of the back cover 3, which abuts against the evaporation film 22. As a safety measure, it is used to prevent leakage. If liquid overflows during use, it will be absorbed by the cotton pad below, preventing the perfume from flowing out and causing leakage.

[0056] 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.

[0057] 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.
