Description

Technical Field

[0001] This utility model relates to the field of aroma diffuser technology for use in homes, cars, offices, etc., and specifically to a lift-type aroma diffuser. Background Technology

[0002] As society develops, people are constantly improving their quality of life. Since the sense of smell is directly connected to the emotional realm of the brain, fragrance can be perceived through smell. From ancient Greece and Rome to early Asian countries, it was believed that fragrance not only brings joy but also influences our mental and physical well-being. Aromatherapy diffusers utilize the unique charm of fragrance to extend communication from sight and hearing to smell, reaching a deeper level, and are therefore used to optimize the environment.

[0003] There are several types of car air fresheners: one is a diffuser stand that sits on a table and diffuses fragrance naturally through the evaporation of aromatic substances; another is an air vent diffuser that clips onto the car's air vent and diffuses fragrance using the air conditioning; and the third is a car air freshener machine that connects to the car's power supply and diffuses fragrance using an internal fan. However, car air freshener machines are generally quite large, especially when they have multiple fragrances and independent fragrance diffusion structures, which can significantly impact the car's interior space and aesthetics. Although there are now cases where the fragrance system is integrated with the air conditioning system and not placed inside the car, in this case, the fragrance system (i.e., the air freshener machine) is usually installed in the car's engine compartment. This makes it inconvenient to replenish or replace the aromatic substances in the fragrance system after they are used up.

[0004] Secondly, the aroma diffusers on the market are currently highly homogenized, with two main structures. One type is based on a humidifier, where essential oils are manually added to achieve a simple aromatherapy function, but this cannot provide a continuous fragrance. The other type uses solid fragrance chips (i.e., fragrance generators) as the fragrance source to achieve a natural and continuous fragrance. However, existing aroma diffusers generally only have one solid fragrance chip, so they can only diffuse one type of fragrance at a time. The fragrance diffusion function is limited and short-lived. When a different fragrance is needed, the solid fragrance chip must be replaced, which is complicated and inconvenient. This cannot meet the needs of users for different fragrances in different situations. Furthermore, the fragrance diffusion is generally achieved through the fragrance diffusion hole at the top, which greatly affects its aesthetics.

[0005] In addition, some existing methods use balm jars as refills. However, regardless of whether liquid or solid aromatherapy is used, when bottled or canned fragrance sources are used as refills for aromatherapy diffusers, the refill is usually installed inside the diffuser. The diffuser must be opened first to remove and replace the internal fragrance jar. The whole process is complicated and inconvenient. Furthermore, the diffuser main unit and base are usually assembled by a snap-fit ​​method, which is not easy to disassemble. That is, after the refill is used up, it is not convenient to separate the main unit and base and remove the internal refill for replacement. Utility Model Content

[0006] The purpose of this utility model is to overcome the existing technical defects and provide a lifting aroma diffuser. It adopts a lifting aroma diffusion structure and can be hidden inside the center console of a car. When in use, the main unit can be raised and extended out of the center console. It also makes it convenient to put in and take out the aroma diffuser for replacement.

[0007] To solve the above-mentioned technical problems, this utility model provides a lifting aroma diffuser, including a hollow outer shell, a main unit that slides up and down inside the outer shell, and a driving device that drives the upper end of the main unit to slide upward out of the outer shell or retract into the outer shell. The main unit is provided with at least one aroma diffuser can for accommodating and dispersing fragrance. The upper end of the main unit is provided with at least one fragrance dispersing channel corresponding to and communicating with the aroma diffuser can. There is a fragrance dispersing gap between the upper end of the main unit and the outer shell, which communicates with the fragrance dispersing channel. The lower end of the main unit is provided with at least one air supply channel corresponding to and communicating with the aroma diffuser can. An upward air supply exhaust device is provided in the air supply channel. The outer shell is provided with several air inlets. After the main unit slides up and down relative to the outer shell, the inlet of the air supply channel and the air inlet are either connected or disconnected.

[0008] Furthermore, the aroma diffuser is provided with a first opening and a second opening on the upper and lower sides respectively to connect with or expose the internal fragrance-emitting body. The first opening is connected to the fragrance dispersing channel, and the second opening is connected to the outlet at the upper end of the air supply channel.

[0009] Furthermore, the lower end of the main unit is provided with an air inlet channel, which is connected to the inlet of the lower end of all air supply channels. A number of flow holes are provided on one side of the air inlet channel. After the main unit slides up and down relative to the outer shell, the flow holes and the air inlet holes are either connected or not connected.

[0010] Furthermore, the main unit is provided with at least one inclined upward or horizontally arranged receiving hole, and the aromatherapy jars are respectively accommodated in the receiving hole, and the upper and lower sides of the receiving hole are provided with openings at the positions corresponding to the first opening and the second opening.

[0011] Furthermore, the inner end of the receiving hole is provided with a self-locking switch for fixing the aromatherapy jar, and the outer end of the receiving hole is a through hole opened on one side of the main unit for inserting the aromatherapy jar.

[0012] Furthermore, the inner end of the receiving hole is provided with a support base for supporting the aromatherapy jar. The inner end of the support base is provided with a fixing post that cooperates with and is fixed to the self-locking switch. A spring is provided between the inner end of the receiving hole and the support base, and a buffer pad is provided at the outer end of the support base.

[0013] Furthermore, a guide positioning structure is provided between the receiving hole and the aromatherapy jar; preferably, positioning planes are provided on the front and rear sides of the receiving hole, and transition planes that cooperate with the positioning planes are provided on the front and rear sides of the aromatherapy jar, and the positioning planes and transition planes cooperate to form the guide positioning structure.

[0014] Furthermore, the main unit includes a hollow shell, a fixed frame disposed within the hollow shell, and a sliding seat fitted around the lower end of the hollow shell and supporting the hollow shell. The aroma diffuser, the fragrance channel, and the air supply channel are all disposed within the fixed frame. One side of the hollow shell has an air outlet at the position corresponding to each of the fragrance channels, and one side of the hollow shell has an opening at the position corresponding to each of the through holes. A fragrance diffusion gap communicating with the air outlet is provided between the upper end of the hollow shell and the outer shell. The driving device includes a first driving device disposed on the sliding seat and used to drive the hollow shell to move up and down.

[0015] Furthermore, the main unit also includes a support frame fixed to the lower end of the fixed frame and located inside the sliding seat. The support frame is provided with the air inlet channel. One side of the support frame is provided with several flow holes that communicate with the air inlet channel and are located inside the sliding seat. One side of the hollow shell is provided with an air inlet at the position corresponding to each of the flow holes. After the hollow shell slides up and down relative to the sliding seat, the air inlet and flow holes protrude upward from the sliding seat or retract into the sliding seat.

[0016] Furthermore, the sliding seat is slidably disposed inside the housing, and the driving device also includes a second driving device disposed at the bottom of the housing and driving the sliding seat to slide up and down. After the sliding seat slides up and down relative to the housing, the opening protrudes upward from the housing or retracts back into the housing.

[0017] Furthermore, the outer shell is provided with at least two vertically arranged guide rails, and the hollow shell and the sliding seat are slidably disposed on the guide rails from top to bottom.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, the main unit is driven by a drive device to slide up and down, allowing it to slide relative to the outer casing. During installation, the entire unit can be concealed inside a car dashboard or office desk, with only the top of the diffuser visible on the dashboard or desk surface. A through-hole for the main unit to move up and down is created on the dashboard or desk surface. During use, the drive device causes the main unit to protrude upwards from the dashboard, connecting the air supply channel at the bottom of the main unit with the air inlet on the outer casing. At this point, opening the exhaust device at at least one of the air supply channels allows for the diffuser to release fragrance. The raising and lowering process of the main unit before and after use provides a clear indication to the user whether the diffuser is in fragrance-releasing mode, preventing the diffuser from releasing fragrance when it is not needed, thus affecting its lifespan and user experience. The raising and lowering process also provides a visually appealing experience for the user.

[0020] Secondly, multiple aromatherapy jars can be installed in the main unit. Each aromatherapy jar can hold the same or different fragrance substances, and each aromatherapy jar has an independent fragrance diffusion channel and air supply channel. As needed, the exhaust device in one of the air supply channels can be turned on to supply air, while the exhaust devices in the other air supply channels are not turned on, so that only one aromatherapy jar is formed to create an up-and-down airflow and diffuse a single fragrance. Alternatively, the exhaust devices in two or more air supply channels can be turned on at the same time to achieve simultaneous diffusion of multiple fragrances or the same fragrance from different aromatherapy jars. In other words, by using the operation of the exhaust device, only one or more aromatherapy jars can diffuse fragrance at a time, which can meet the needs of different diffusion amounts of the same fragrance, as well as the needs of different fragrance diffusion and switching operations.

[0021] In addition, the driving device includes a first driving device and a second driving device. The first driving device mainly drives the hollow shell of the main unit and the components fixed on it to move upward as a first-level lifting motion, so as to realize the purpose of raising the main unit to release fragrance and lowering it to close. The second driving device drives the entire main unit to rise further on the basis of the first-level lifting motion, as a second-level lifting motion, so that the opening in the main unit for inserting the aroma diffuser is raised and placed outside the outer shell. Through the action of the self-locking switch and the spring, the aroma diffuser can be popped out by pressing it. When inserting the aroma diffuser, pressing it will lock the fixing post with the self-locking switch, thus facilitating the insertion, removal and replacement of the aroma diffuser.

[0022] 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

[0041] 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.

[0042] 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.

[0043] Example

[0044] like Figures 1 to 15 As shown in the figure, the lifting aroma diffuser 100 of this embodiment includes a hollow outer shell 1, a main unit 2 that slides vertically within the outer shell 1, and a driving device that drives the upper end of the main unit 2 to slide upward out of the outer shell 1 or retract into the outer shell 1. The main unit 2 is provided with at least one aroma diffuser 3 for accommodating the fragrance-generating body 30 and dispersing fragrance. In this embodiment, three aroma diffuser 3 are used as an example, that is, the main unit can accommodate three different fragrance types and disperse fragrance. Of course, it can accommodate three aroma diffuser 3 of the same fragrance type. The fragrance-generating body is preferably a solid perfume paste or a cotton pad that has absorbed the fragrance liquid, etc. The upper end of the main unit 2 is provided with three fragrance dispersing channels 20 that correspond one-to-one with the aroma diffuser 3. There is a fragrance dispersing gap 21 between the upper end of the main unit 2 and the outer shell 1 that communicates with the fragrance dispersing channels 20. The lower end of the main unit 2 is provided with three air supply channels 22 that correspond one-to-one with the aroma diffuser 3. The air supply channels 22 are provided with upward air supply channels. The exhaust device 4, when activated within the corresponding air supply channel 22, allows air to flow upwards through the corresponding aromatherapy jar 3, and then outwards through the fragrance diffusion channel and gaps. The design structure, with multiple independent channels and multiple aromatherapy jars corresponding to each other, allows for the activation of the exhaust device in one air supply channel as needed, while keeping the exhaust devices in other channels closed. This creates an up-and-down airflow within only one aromatherapy jar, dispersing a single fragrance. Alternatively, the exhaust devices in two or more air supply channels can be activated simultaneously to diffuse multiple fragrances or the same fragrance from different jars at the same time. In other words, by controlling the operation of the exhaust device, only one or more aromatherapy jars can diffuse fragrance simultaneously, satisfying the need for different amounts of the same fragrance, as well as the need for different fragrances and switching operations.

[0045] like Figures 1 to 3 As shown, in order to achieve the purpose of air intake, several air inlets 10 are provided on the outer casing 1. After the main unit 2 slides up and down relative to the outer casing 1, the inlet of the air supply channel 22 and the air inlet 10 are either connected or disconnected. That is, after the main unit 2 slides upward under the action of the driving device, the inlet of the air supply channel 22 and the air inlet 10 are connected. At this time, after the exhaust device works, air can be drawn in from outside the casing. After the main unit 2 slides down and returns to its original position under the action of the driving device, the inlet of the air supply channel 22 and the air inlet 10 are disconnected. That is, at this time, the inlet of the air supply channel 22 is closed, and the air outside the casing can basically not enter the main unit. That is, there is no active air flowing up and down between the air supply channel and the fragrance channel, which avoids the problem of large volatile fragrance dispersion and short service life when not in use.

[0046] In the above, the main unit is first driven by a drive device to slide up and down, realizing the up and down sliding of the main unit relative to the outer shell. During installation, the entire unit can be hidden inside the vehicle's center console; only the top of the lift-up aroma diffuser 100 needs to be exposed on the dashboard 101 (e.g., Figure 16 and Figure 17 As shown in the diagram, a through hole is opened on the surface of the car's center console for the main unit to move up and down. When in use, the main unit is protruded upward from the center console by the drive device, thereby connecting the air supply channel at the bottom of the main unit with the air inlet on the outer shell. At this time, the exhaust device at at least one of the air supply channels can be turned on to disperse the fragrance. The lifting and lowering process of the main unit before and after use allows the user to more intuitively know whether the aroma diffuser is in the fragrance dispersing state, avoiding the diffusion of fragrance when it is not needed, which would affect the service life and user experience. The lifting and lowering process also provides the user with a visual viewing effect.

[0047] It is understandable that using this aroma diffuser inside a car's center console is only one of its best applications, not its only application. No specific limitations are made here. In practice, the aroma diffuser can also be hidden and installed under an office desk. When using it, the main unit simply needs to be raised and protrude from the office desk surface, reducing its occupation of indoor space and its impact on the overall layout of the room.

[0048] It is understandable that the number of aromatherapy jars on the main unit can be one, two, four or more, without specific limitations, only based on actual needs.

[0049] As a preferred option, such as Figures 2 to 4As shown, in order to allow air to enter and exit the aroma diffuser, a first opening 31 and a second opening 32 are respectively provided on the upper and lower sides of the aroma diffuser 3 to connect with or expose the internal fragrance emitter 30. The first opening 31 is connected to the fragrance dispersing channel 20, and the second opening 32 is connected to the outlet at the upper end of the air supply channel 22. That is, the air delivered upward by the air supply channel 22 flows into the aroma diffuser through the second opening 32 and comes into contact with the fragrance emitter 30. Then the air flows upward through the first opening 31 into the fragrance dispersing channel 20 and finally flows out from the fragrance dispersing gap 21, thus achieving the purpose of dispersing fragrance outward.

[0050] In one embodiment, such as Figures 2 to 3 As shown, the lower end of the main unit 2 is also provided with an air inlet channel 23, which is connected to the inlet of the lower end of the three air supply channels 22. A number of flow holes 24 are provided on one side of the air inlet channel 23. During the process of the main unit 2 moving up and down, the flow holes 24 and the air inlet holes 10 are either connected or not connected. That is, when it rises, it is connected, so that air can enter the main unit and diffuse fragrance. When it falls, it is not connected, so that air cannot enter the main unit and diffuse fragrance.

[0051] In one embodiment, such as Figures 2 to 10 As shown, the main unit 2 includes a hollow shell 200, a fixing frame 201 fixed inside the hollow shell 200 by screws, and a sliding seat 202 fitted outside the lower end of the hollow shell 200 and providing upward support for the hollow shell 200. The aroma diffuser 3, the fragrance channel 20, and the air supply channel 22 are all located inside the fixing frame 201. One side of the hollow shell 200 has an air outlet 203 at the position corresponding to each fragrance channel 20. There is a fragrance diffusion gap 21 between the upper end of the hollow shell 200 and the outer shell 1, which communicates with the air outlet 203. The driving device includes a first driving device 5 vertically mounted on the sliding seat 202 and used to drive the hollow shell 200 to move up and down. The first driving device 5 drives the hollow shell 200 to move up and down relative to the sliding seat 202. As a first-stage lifting motion, the main unit is raised to diffuse fragrance and lowered to close.

[0052] As a preferred option, such as Figures 2 to 13As shown, the main unit 2 also includes a support frame 204 fixed to the lower end of the fixing frame 201 by screws and located inside the sliding seat 202. The support frame 204 has an air inlet channel 23. One side of the support frame 204 has several flow holes 24 communicating with the air inlet channel 23 and located inside the sliding seat 202. One side of the hollow housing 200 has an air inlet 205 at the position corresponding to each flow hole 24. The sliding seat 202 can be used to close the air inlet 205 and the flow holes 24. After the hollow housing 200 slides up and down relative to the sliding seat 202, the air inlet 205 and the flow holes 24 protrude upwards from the sliding seat 202 or retract into the sliding seat 202, thereby making the air inlet 205 and the flow holes 24 protruding from the sliding seat 202 in a connected state with the air inlet 10 (e.g., Figures 10 to 13 As shown), the air inlet 205 and flow hole 24, which retract into the sliding seat, are sealed by the sliding seat 202, and are not connected to the air inlet 10, so as to achieve the purpose of air intake and fragrance dissemination of the main unit and sealing off the air intake (as shown). Figure 5 (As shown).

[0053] In one embodiment, such as Figures 2 to 9 As shown, the mounting bracket 201 has three inclined upward or horizontally arranged receiving holes 206, preferably inclined upward, to facilitate the insertion and removal of the aromatherapy jars. The aromatherapy jars 3 are accommodated in the receiving holes 206 one by one, and the upper and lower sides of the receiving holes 206 are provided with openings at the positions corresponding to the first opening 31 and the second opening 32, so as to realize the vertical flow and communication of air.

[0054] As a preferred option, such as Figures 2 to 7 As shown, a self-locking switch 207 for fixing the aromatherapy jar 3 is provided on the inner end of the receiving hole 206, and the outer end of the receiving hole 206 is a through hole opened on one side of the fixing frame 201 for the aromatherapy jar 3 to be inserted. An opening 209 is provided on one side of the hollow shell 200 at the position corresponding to each through hole.

[0055] In one embodiment, such as Figures 2 to 7As shown, the inner end of the receiving hole 206 is also provided with a support base 34 for supporting the aromatherapy jar 3. The inner end of the support base 34 has a protruding fixing post 35 that cooperates with the self-locking switch 207 for fixation. A spring 36 is provided between the inner end of the receiving hole 206 and the support base 34. A buffer pad 37 is provided at the outer end of the support base 34. The buffer pad is preferably a silicone pad. The cooperation of the self-locking switch 207, the spring 36 and the support base 34 facilitates the insertion and removal of the aromatherapy jar 3. When inserting the aromatherapy jar 3, pressing it will lock the fixing post 35 with the self-locking switch 207. At this time, the spring 36 is in a compressed state. When it is necessary to remove the aromatherapy jar 3, the support base 34 and the self-locking switch 207 can be unlocked by pressing the aromatherapy jar 3. Then, the aromatherapy jar 3 can be popped outward by the action of the spring 36, so that the outer end of the aromatherapy jar 3 protrudes out of the hollow shell 200. Then, the aromatherapy jar 3 can be pulled outward.

[0056] It is understandable that, such as Figures 4 to 8 As shown, in order to facilitate the insertion of the aroma diffuser and to make the opening on the aroma diffuser correspond and connect with the opening on the fixing frame, a guide positioning structure is provided between the receiving hole 206 and the aroma diffuser 3; preferably, a positioning plane 208 is provided on the front and rear sides of the receiving hole 206, and a transition plane 33 that cooperates with the positioning plane 208 is provided on the front and rear sides of the aroma diffuser 3. The positioning plane 208 and the transition plane 33 cooperate to form a guide positioning structure.

[0057] In one embodiment, such as Figures 12 to 15 As shown, the sliding seat 202 is slidably disposed inside the outer shell 1. The driving device also includes a second driving device 6 that is vertically disposed at the bottom of the outer shell 1 and drives the sliding seat 202 to slide up and down. After the sliding seat 202 slides up and down relative to the outer shell 1, it drives the upper hollow shell 200 and other components fixed on the hollow shell 200 to slide up and down synchronously. As a secondary lifting motion, after sliding upward, the opening on the hollow shell 200 protrudes upward from the outer shell 1. At this time, the aroma diffuser 3 in the receiving hole can be taken out and the replacement aroma diffuser can be put into the receiving hole. After sliding downward, the opening on the hollow shell 200 retracts downward into the outer shell 1, so that the aroma diffuser 3 is hidden inside the aroma diffuser.

[0058] In one embodiment, such as Figures 2 to 6 As shown, the outer casing 1 is provided with three vertically arranged guide rails 11. The hollow casing 200 and the sliding seat 202 are slidably mounted on the guide rails 11 from top to bottom through linear bearings, which play a guiding and stabilizing role in the up and down sliding process of the main unit.

[0059] In another embodiment, such as Figure 2As shown, a control board 7 is also provided inside the main unit. The control board 7 is electrically connected to the first drive device 5, the second drive device 6, and the exhaust device 4. The control board 7 can also be connected to the vehicle power supply and the vehicle central control screen to realize the control of the aroma diffuser.

[0060] Understandably, in practical applications, the aroma diffuser can also be equipped with a remote control, APP, or mini-program that communicates with the control board. The aroma diffuser can be controlled by the remote control, APP, or mini-program, making it suitable for remote control or mobile phone control in places such as cars, homes, or offices.

[0061] In another embodiment, such as Figures 1 to 2 As shown, a decorative piece 8 is provided between the upper ends of the outer casing 1 and the main unit 2, surrounding the main unit 2. This decorative piece 8 is snap-fitted into the outer casing 1. During installation, the decorative piece 8 is fixed to the surface of a vehicle's center console or an office desk (e.g., ...) using screws. Figure 16 and Figure 17 (As shown), this improves the aesthetics after installation.

[0062] In other embodiments, the ventilation device is a fan.

[0063] In other embodiments, both the first driving device and the second driving device are vertically arranged electric push rods or cylinders, etc.
