Description

TECHNICAL FIELD

[0001] The application relates to the technical field of vehicle-mounted fragrance, and particularly discloses a fragrance device with automatic feeding. BACKGROUND

[0002] The vehicle-mounted fragrance is a fragrance product specially used in the interior of a vehicle, aiming to improve the air quality in the vehicle and provide a pleasant driving experience. The main function of the vehicle-mounted fragrance is to remove odors in the vehicle, such as new car smell, cigarette smell and the like, and to add pleasant fragrance to the space in the vehicle, thereby creating a comfortable driving and riding environment.

[0003] According to the form of the fragrance, the vehicle-mounted fragrance can be divided into liquid perfume, solid balm, solid fragrance beads, sachet, spray, essential oil and carrier medium and the like. These different types of fragrances have different characteristics, such as the liquid perfume having rich taste but not resistant to high temperature, the solid balm having high safety factor but having light taste and the like.

[0004] The vehicle-mounted fragrance mainly blows the aromatherapy essential oil into the air in the vehicle through the built-in fan, so as to release the fragrance and increase the comfort in the vehicle.

[0005] The common vehicle-mounted fragrances have the problems of bottle, fragrance sheet and solid fragrance beads, and cannot realize automatic feeding of the fragrance. In some cases, the experience of the driver and passenger is affected because the driver and passenger cannot know the remaining amount of the fragrance. Therefore, the application provides a fragrance device with automatic feeding. CONTENT OF THE INVENTION

[0006] The application aims to solve the problem that the traditional vehicle-mounted fragrance device cannot realize automatic feeding of the fragrance.

[0007] In order to achieve the above-mentioned purpose, the application provides the following basic scheme.

[0008] The fragrance device with automatic feeding comprises a fragrance assembly arranged at the air outlet position of the vehicle.

[0009] The fragrance assembly comprises a frame assembly and a plurality of fragrance pieces movably arranged on the frame assembly.

[0010] The fragrance piece comprises a fragrance main body, ventilation grooves penetrating through the front and back of the fragrance main body, sliding columns symmetrically and fixedly connected to the both ends of the fragrance main body and slidably connected to the frame assembly, a connecting plate arranged at the bottom of the fragrance main body, a thin film pressure sensor arranged on the connecting plate, a fragrance gas generating body filled in the fragrance main body and a fragrance gas generating body storage box arranged at the top of the fragrance main body. The fragrance gas generating body storage box is opened based on the pressure threshold value of the thin film pressure sensor.

[0011] The principle and effect of the basic scheme are as follows.

[0012] 1. Compared with existing technologies, this device has a simple structure, multiple fragrance components, and can move up and down. The up and down movement of the fragrance components allows different fragrance components to act on the car's air vents, thereby achieving the diffusion of different fragrance components and solving the problem that traditional car fragrance devices cannot switch fragrance scents at will.

[0013] 2. Compared with existing technologies, this device does not use the electrical structure of a fragrance generator. Although the replacement mode is manual and not very elegant, it still has its own advantages, namely cost advantage. Since it is a car fragrance, it is not an essential item. Therefore, gaining a cost advantage is more conducive to the product's market share. Furthermore, in terms of cost advantage, the fragrance component includes a frame component and several fragrance elements that can move up and down on the frame component. The fragrance elements are independent of the frame component, meaning that the fragrance elements can be purchased separately after use, which can save the purchase cost of the frame component, thereby reducing the purchase cost of this product and ultimately gaining market competitiveness.

[0014] 3. Compared with existing technologies, this device features a connecting plate at the bottom of the fragrance unit, a thin-film pressure sensor mounted on the connecting plate, a fragrance gas generator filled inside the fragrance unit, and a fragrance gas generator storage box located at the top of the fragrance unit. The fragrance gas generator storage box additionally stores the fragrance gas generator. Based on the fact that the fragrance gas generator will be consumed due to wind, a thin-film pressure sensor is installed to sense the weight of the fragrance gas generator. When the weight drops to a certain level, the gas generator storage box replenishes the fragrance gas generator, thereby solving the problem that traditional in-vehicle fragrance devices cannot achieve automatic fragrance dispensing.

[0015] Furthermore, the frame assembly has a unique air inlet corresponding to the car's air vent. Fragrance components with different scents are installed at the air inlet position after being moved up and down and are acted upon by the car's air vent. The frame assembly includes a frame body, a support frame set at one end of the frame body, an adhesive body set at the free end of the support frame, and an end cap set at the other end of the frame body and fixed to the frame body. The end cap has a notch, and the air inlet is set on the frame body near the car's air vent at the notch position.

[0016] Furthermore, the adhesive body includes a connecting plate and adhesive disposed on the connecting plate. The adhesive is disposed on the vehicle dashboard near the vehicle's air vent, and the air outlet direction of the vehicle's air vent is on the same plane as the air inlet direction. This achieves a fixed installation of the device.

[0017] Furthermore, a glass observation plate is embedded in the end cap, and the glass observation plate and the end cap are integrally formed. This allows for observation and selection of the appropriate fragrance component during manual operation.

[0018] Furthermore, the frame body has a U-shaped groove, with its starting end at the top and ending end at the bottom. The fragrance unit is slidably connected within this U-shaped groove, and the surface area of ​​the fragrance unit is equal to the surface area of ​​the notch. The coverage area of ​​the air inlet is greater than the surface area of ​​the notch. This achieves integrated fragrance unit functionality, which can be purchased separately, thereby increasing the market appeal of the device.

[0019] Furthermore, it also includes an anti-detachment component for the fragrance diffuser to prevent it from popping out. The anti-detachment component consists of several connecting bolts, and the frame body has several connecting holes. After the connecting bolts are connected to the connecting holes, they seal the upper end of the slide groove. Since this product is for vehicle use, there may be shaking situations such as sudden braking. To prevent the fragrance diffuser from popping out, an anti-detachment component is designed. The anti-detachment component can prevent the fragrance diffuser from jumping out from the upper end of the slide groove.

[0020] Furthermore, the fragrance gas generator is a solid fragrance bead. Solid fragrance beads are chosen because, compared to solid perfume balms, their unique solid form tightly encapsulates the fragrance molecules within the bead, resulting in a more stable and longer-lasting fragrance release. Simultaneously, solid fragrance beads are less susceptible to external environmental influences such as temperature and humidity, thus ensuring the long-term stability of the fragrance.

[0021] Furthermore, the top of the fragrance unit has a through slot, and the fragrance gas generator storage box is connected to the through slot. The fragrance gas generator storage box includes a connecting channel connected to the through slot, a storage box body fixed to the connecting channel, and a sealing plate disposed at the connection between the storage box body and the connecting channel for sealing the connecting channel. Motors are symmetrically installed on the inner wall of the storage box body, and the output end of the motor is connected to the sealing plate to drive the sealing plate to deflect. The connection between the fragrance gas generator storage box and the fragrance unit is achieved through the motor, thereby allowing the fragrance gas generator inside the fragrance gas generator storage box to be introduced into the fragrance unit.

[0022] Furthermore, the support frame has battery mounting slots and controller mounting slots. The battery mounting slots house several batteries, and the controller mounting slots house the controller. The batteries power the controller and the diaphragm pressure sensor. The controller controls the motor start-up based on a threshold set by the diaphragm pressure sensor. This is primarily because after productization, the various components need to be arranged rationally; therefore, the battery mounting slots and controller mounting slots are provided to house the batteries and controller.

[0023] Furthermore, the thin-film pressure sensor is model JYH-FSR-008, which is a pressure-sensitive series. The thin-film pressure sensor is embedded in the connecting plate, and the upper surface of the connecting plate and the pressure-receiving surface of the thin-film pressure sensor are on the same plane. The motor is a forward and reverse reversible motor. Attached Figure Description

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] The reference numerals in the accompanying drawings include: support frame 1, connecting plate 2, frame body 3, slide groove 4, end cap 5, air inlet 6, glass observation plate 7, connecting bolt 8, fragrance component 9, through groove 10, storage box body 11, fragrance gas generator storage box 12, motor 13, connecting channel 14, adhesive 15, battery mounting slot 16, controller mounting slot 17, opening cover 901, force point 902, sliding column 903, fragrance body 904, ventilation slot 905, fragrance gas generator 906, and membrane pressure sensor 907.

[0034] Implementation, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown:

[0035] An automatic dispensing fragrance device includes a fragrance component positioned at the air vent of a car.

[0036] The fragrance assembly includes a frame assembly and several fragrance components 9 that can move up and down on the frame assembly;

[0037] The fragrance component 9 includes a fragrance body 904, a ventilation slot 905 extending through the front and rear of the fragrance body 904, sliding columns 903 symmetrically fixed to both ends of the fragrance body 904 and slidably connected to the frame assembly, a connecting plate disposed at the bottom of the fragrance body 904, a thin-film pressure sensor 907 mounted on the connecting plate, a fragrance gas generator 906 filled in the fragrance body 904, and a fragrance gas generator storage box 12 disposed at the top of the fragrance body 904, wherein the fragrance gas generator storage box 12 is opened based on a pressure threshold set by the thin-film pressure sensor 907.

[0038] About framework components:

[0039] The frame assembly has a unique air inlet 6 corresponding to the car's air vent. Fragrance components 9 with different scents are installed at the air inlet 6 after moving up and down and are acted upon by the car's air vent. The frame assembly includes a frame body 3, a support frame 1 located at the right end of the frame body 3, an adhesive 15 located at the free end of the support frame 1, and an end cap 5 located at the other end of the frame body 3 and fixedly connected to the frame body 3. The end cap 5 has a notch, and the air inlet 6 is located on the frame body 3 near the car's air vent at the notch.

[0040] The adhesive 15 includes a connecting plate 2 and adhesive 15 disposed on the connecting plate 2. The adhesive 15 is disposed on the dashboard of the car near the car's air vent, and the air outlet direction of the car's air vent is on the same plane as the air inlet 6. This achieves the fixed installation of the device.

[0041] A glass observation plate 7 is embedded in the end cap 5, and the glass observation plate 7 and the end cap 5 are integrally formed. This allows for observation and selection of the appropriate fragrance component 9 during manual operation.

[0042] Since the fragrance component 9 in this case needs to be moved up and down manually, it is not easy to find the desired fragrance scent by using a solid end cap 5. Therefore, a glass observation plate 7 is provided. The transparency of the glass observation plate 7 is used to observe where the desired fragrance component 9 is located, so as to complete the manual replacement.

[0043] The first core feature of this product is its ability to switch fragrances:

[0044] Specifically: The frame body 3 has a sliding groove 4, which is a U-shaped groove. The starting end of the U-shaped groove is at the top of the frame body 3, and the ending end of the U-shaped groove is at the bottom of the frame body 3. The fragrance component 9 is slidably connected in the U-shaped groove to realize the integration of the fragrance component 9. The integrated fragrance component 9 can be purchased separately, thereby increasing the market stickiness of this device.

[0045] The main purpose of the notch is to be used in conjunction with car air vents and fragrance components.

[0046] Since the airflow from the car's air vent can only be felt at the notch position, and not at other positions, by sliding the fragrance component 9 in the U-shaped groove, different fragrance components 9 can be switched to the notch position to diffuse the fragrance.

[0047] To elaborate further:

[0048] To maximize and optimize the aroma output, the surface area of ​​the fragrance component 9 is equal to the surface area of ​​the notch, and the coverage of the air inlet 6 is greater than the surface area of ​​the notch. The main purpose is to ensure that the fragrance body 904 can receive the full airflow.

[0049] The top of the fragrance body 904 is an openable cover 901, with a force-bearing point 902 on the cover 901. The force-bearing point 902 is mainly the fragrance body 904. The openable cover 901 is snap-fitted to the fragrance body 904. A through groove 10 is formed on the openable cover 901, and the fragrance gas generator storage box 12 is connected to the through groove 10. The fragrance gas generator storage box 12 includes a connecting channel 14 connected to the through groove 10, a storage box body 11 fixedly connected to the connecting channel 14, and a sealing plate set at the connection between the storage box body 11 and the connecting channel 14 for sealing the connecting channel 14. Motors 13 are symmetrically installed on the inner wall of the storage box body 11. The output end of the motor 13 is connected to the sealing plate to drive the sealing plate to deflect. The motor 13 enables the connection between the fragrance gas generator storage box 12 and the fragrance body 904, so that the fragrance gas generator 906 inside the fragrance gas generator storage box 12 can be put into the fragrance body 904.

[0050] Then, the support frame 1 has a battery mounting slot 16 and a controller mounting slot 17. The battery mounting slot 16 contains several batteries, and the controller mounting slot 17 contains a controller. The batteries power the controller and the thin-film pressure sensor 907. The controller controls the motor 13 to start based on the threshold set by the thin-film pressure sensor 907. This is mainly because after productization, the various components need to be arranged reasonably, hence the battery mounting slot 16 and controller mounting slot 17 are provided to house the batteries and controller. The thin-film pressure sensor 907 is model JYH-FSR-008, a pressure-sensitive series. The thin-film pressure sensor 907 is embedded in the connecting plate, and the upper surface of the connecting plate and the pressure-bearing surface of the thin-film pressure sensor 907 are on the same plane. The motor 13 is a forward and reverse reversible motor 13.

[0051] Specifically:

[0052] Since the fragrance gas generator 906 is consumed by wind, a thin-film pressure sensor 907 is installed to sense the weight of the fragrance gas generator 906. When the weight drops to a certain level, the motor 13 starts, causing the sealing plate to deflect and the gas generator storage box to open, thereby replenishing the fragrance gas generator 906. This solves the problem that traditional car fragrance devices cannot achieve automatic fragrance dispensing.

[0053] In this case:

[0054] In this case, the fragrance gas generator 906 is made of solid fragrance beads, which are filled inside the fragrance body 904. Solid fragrance beads were chosen because, compared to solid perfume balms, their unique solid form tightly encapsulates the fragrance molecules, resulting in a more stable and longer-lasting fragrance release. Furthermore, solid fragrance beads are less susceptible to external environmental factors such as temperature and humidity, thus ensuring the long-term stability of the fragrance.

[0055] Secondly, since the thin-film pressure sensor 907 is needed to sense the weight of the fragrance gas generator 906, the solid fragrance bead structure is more stable and can better cooperate with the thin-film pressure sensor 907.

[0056] In practical use, since this device is for vehicle use, there are situations where cars brake and stop suddenly. Returning to the fragrance unit, in such a situation, the fragrance unit might jump out of the slide 4. Therefore, to avoid this situation:

[0057] It also includes an anti-detachment component for the fragrance component 9 to prevent it from popping out. The anti-detachment component consists of several connecting bolts 8. Several connecting holes are opened on the frame body 3. After the connecting bolts 8 are connected to the connecting holes, they seal the upper end of the slide groove 4. Since it is used in a vehicle, there may be shaking such as sudden braking. In order to prevent the fragrance component from popping out, the anti-detachment component is designed. The anti-detachment component can prevent the fragrance component 9 from jumping out from the upper end of the slide groove 4.

[0058] Specifically:

[0059] The connecting bolt 8 and the connecting hole are located at the upper end of the slide groove 4. If the fragrance component 9 jumps out from the upper end of the slide groove 4, the fragrance component 9 will be blocked by the connecting bolt 8, and thus the fragrance component 9 will not be able to jump out.

[0060] This device solves the problem that traditional car air fresheners cannot automatically add fragrance.

[0061] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
