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 multi-functional 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 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 after they are used up. Furthermore, existing air freshener machines generally only have a fragrance diffusion function, which is simple and lacks aesthetic appeal. Even patent publication number CN219630241 The smoke diffuser shown in U can only be used by sticking it to the center console. In order to diffuse the fragrance, the smoke from this diffuser is discharged upwards into the car. The smoke discharged into the car will greatly obstruct the view through the windshield and condense into water droplets on the windshield, affecting driving safety. In addition, the humidity inside the car will increase significantly, affecting the user experience.

[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

The driving device also includes a second driving device disposed at the bottom of the outer casing and driving the sliding seat to slide up and down. The second driving device is electrically connected to the control board. After the sliding seat slides up and down relative to the outer casing, the opening protrudes upward from the outer casing or retracts into the outer casing.

[0022] This utility model has the following beneficial effects:

[0023] 1. Firstly, the main unit uses a drive mechanism to slide up and down, allowing it to move 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 surface. This is achieved by creating a through-hole on the dashboard for the main unit to move up and down, solving the problem of existing smoke diffusers taking up interior space and affecting aesthetics when placed outside. In use, the drive mechanism causes the main unit to protrude upwards from the dashboard, thus allowing the lower part of the main unit to move up and down. The air supply channel is connected to 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 raising and lowering process of the main unit before and after use allows users to more intuitively know whether the aroma diffuser is in the fragrance dispersion state, avoiding the dispersion of fragrance when it is not needed, which will affect the service life and user experience. At the same time, during the fragrance dispersion process, the visual cavity at the top of the main unit also protrudes from the center console. At this time, the atomizer works, and the atomized smoke enters the top of the cavity along the smoke inlet channel. Then the smoke flows down along the smoke channel to form a smoke landscape.

[0024] 2. Multiple aromatherapy jars can be installed in the main unit. Each aromatherapy jar can hold the same or different fragrance substances. Each aromatherapy jar has an independent fragrance diffusion channel and air supply channel. As needed, the exhaust device in one air supply channel can be turned on to supply air, while the exhaust devices in other air supply channels are not turned on. This creates an up-and-down airflow in only one aromatherapy jar to diffuse a single fragrance. Alternatively, the exhaust devices in two or more air supply channels can be turned on simultaneously to diffuse multiple fragrances or the same fragrance from different aromatherapy jars at the same time. 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 amounts of the same fragrance, as well as the needs of different fragrances and the switching operation.

[0025] 3. A light panel was added to the top of the cavity to illuminate the interior and create a lighting effect, which, together with the smoke, further enhances the aesthetics and visual appeal. Furthermore, the smoke entering the cavity is discharged downwards and led out of the outer shell, avoiding the problem of smoke obstructing the view of the windshield or condensing into water droplets on the windshield, thus improving driving safety. This achieves the visual effect of the smoke landscape without affecting the user experience inside the vehicle.

[0026] 4. 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, realizing 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 based on the first-level lifting motion, as a second-level lifting motion, so that the opening in the main unit used to insert 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.

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.

[0053] 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.

[0054] Example

[0055] like Figures 1 to 21As shown in the figure, the multifunctional 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 jar 3 for accommodating and dispersing fragrance. In this embodiment, three aroma diffuser jars 3 are used as an example, that is, the main unit can accommodate three different fragrances and disperse fragrance. Of course, it can accommodate three aroma diffuser jars with the same fragrance. The fragrance-generating body is preferably a solid perfume paste or a cotton pad that has absorbed the fragrance liquid. 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 jars 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 jars 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.

[0056] like Figures 1 to 5 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.

[0057] As a preferred option, such as Figures 3 to 4As shown, in order to achieve the visual effect of the aroma diffuser, a visible cavity 300 is provided on the top of the main unit 2. That is, during the up and down movement of the main unit 2, the visible cavity 300 slides upward out of the outer shell 1 or retracts into the outer shell 1, so that after it protrudes out of the outer shell 1, the inside of the cavity 300 can be viewed by people. A raised mist inlet channel 301 is provided in the middle of the bottom of the cavity 300, and a smoke channel 302 is formed between the top of the mist inlet channel 301 and the top of the cavity 300, so that the smoke flows in all directions. After the smoke enters from the top of the cavity 300, it flows down along the smoke channel 302 to form a smoke landscape. The main unit 2 is provided with an atomizer 9 for generating smoke, and the mist outlet of the atomizer 9 is connected to the mist inlet channel 301.

[0058] 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 22 and Figure 23 As shown in the diagram, a through-hole is created on the dashboard of the vehicle's center console for the main unit to move up and down, solving the problem that existing smoke diffusers occupy interior space and affect aesthetics when placed outside. During use, the main unit is protruded upwards from the center console by a drive mechanism, connecting the air supply channel at the bottom of the main unit with the air inlet on the outer casing. Activating the exhaust device at at least one of the air supply channels allows for outward fragrance dissemination. The raising and lowering process of the main unit before and after use provides a clear indication to the user whether the diffuser is disseminating fragrance, preventing unintended dissemination that could affect its lifespan and user experience. Simultaneously, during fragrance dissemination, the visual cavity at the top of the main unit also protrudes from the center console. At this time, the atomizer operates, and the atomized smoke enters the top of the cavity along the smoke inlet channel, then flows downwards along the smoke channel to create a smoke effect.

[0059] 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.

[0060] 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.

[0061] Understandably, this multi-functional aroma diffuser can be used with both fragrance diffusion and atomization functions activated simultaneously, or either function can be activated separately.

[0062] As a preferred option, such as Figures 4 to 6 As 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.

[0063] In one embodiment, such as Figures 4 to 5 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.

[0064] In one embodiment, such as Figures 2 to 13 As shown, the bottom of the outer casing 1 is provided with a base plate 12, and a smoke exhaust device 500 located below the main unit 2 is provided on the base plate 12. Several smoke exhaust holes 303 are provided around the bottom of the cavity 300. The bottom of the main unit 2 is provided with an opening connecting the smoke exhaust holes 303 and the air inlet of the smoke exhaust device 500. The base plate 12 is provided with a smoke exhaust channel 13 that connects to the air outlet of the smoke exhaust device 500. The outer end of the smoke exhaust channel 13 is provided with a connecting nozzle 14 extending out of the outer casing 1. An external smoke exhaust pipe (not shown in the figure) can be connected using the connecting nozzle 14. The smoke can then be discharged to the bottom of the vehicle or other locations using the external smoke exhaust pipe. That is, the downward-flowing smoke is discharged downward from the smoke exhaust holes 303 and is absorbed by the smoke exhaust device 500 before being discharged outward. This allows the smoke to be discharged directly outside the vehicle, avoiding the problem of smoke obstructing the view of the windshield inside the vehicle and condensing into water droplets on the windshield. This improves driving safety and achieves the aesthetic effect of the smoke landscape without affecting the user experience inside the vehicle.

[0065] In one embodiment, such as Figures 3 to 11As shown, the main unit 2 includes a hollow shell 200, a transparent chamber 304 located on the top of the 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.

[0066] Among them, such as Figures 3 to 4 As shown, the atomizer 9 is located inside the hollow shell 200. A cavity 300 is formed between the transparent chamber 304 and the hollow shell 200. A protruding guide section 305 is provided in the middle of the top of the hollow shell 300. A mist inlet channel 301 is provided through the middle of the guide section 305. A smoke channel 302 is formed between the top of the guide section 305 and the top of the cavity 300. Several smoke exhaust holes 303 located inside the transparent chamber 304 are provided around the top of the hollow shell 200. An opening connecting the smoke exhaust holes 303 and the air inlet of the smoke exhaust device 500 is provided at the bottom of the hollow shell 200.

[0067] Among them, such as Figures 8 to 9 As shown, the driving device includes a first driving device 5 vertically mounted on the sliding seat 202 and used to drive the hollow housing 200 to move up and down. The first driving device 5 drives the hollow housing 200 to move up and down relative to the sliding seat 202. As a first-level lifting motion, it realizes the purpose of raising the main unit to release fragrance and lowering it to close, and simultaneously realizes the purpose of raising the visualization cavity for viewing.

[0068] As a preferred option, such as Figures 4 to 15 As 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 atomizer 9 is located at the lower end of the support frame 204. The upper end of the support frame 204 is provided with a mist outlet 306 communicating with the mist outlet of the atomizer 9. The mist outlet 306 is connected to the mist inlet channel 301 through a bent hose 307. The support frame 204 is provided with an air inlet channel 23. One side of the support frame 204 is provided with several air inlets communicating with the air inlet channel 23 and located inside the sliding seat 202. The hollow housing 200 has an air inlet 205 on one side corresponding to each air inlet 24, which can be closed by the sliding seat 202. After the hollow housing 200 slides up and down relative to the sliding seat 202, the air inlet 205 and the air inlet 204 protrude upward from the sliding seat 202 or retract into the sliding seat 202, thereby making the air inlet 205 and the air inlet 24 protruding from the sliding seat 202 in a connected state with the air inlet 10 (e.g., Figures 16 to 18As 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).

[0069] In one embodiment, such as Figures 4 to 12 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.

[0070] As a preferred option, such as Figures 4 to 12 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.

[0072] It is understandable that, such as Figures 6 to 10 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.

[0073] In one embodiment, such as Figures 18 to 21As 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.

[0074] In one embodiment, such as Figures 3 to 4 As shown, the base plate 12 is provided with three vertically arranged guide rails 11. The hollow housing 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.

[0075] In one embodiment, such as Figure 15 As shown, the atomizer 9 is a conventional heated atomizer, which includes an oil tank 91 with a liquid storage chamber 90, an air pipe 92 located in the middle of the oil tank 91, and an atomizing core located in the air pipe 92 and connected to the liquid storage chamber 90. The liquid storage chamber 90 is provided with a liquid storage element 93 surrounding the air pipe 92 for storing a liquid matrix (preferably water) for heating and atomizing. The atomizing core is used to draw in the liquid matrix in the liquid storage chamber 90 and heat and atomize it. The upper end of the oil tank 91 is provided with an air outlet 94 connecting the mist outlet 306 and the air pipe 92. The air pipe 92 has a liquid guiding hole 920 on its wall at the position corresponding to the atomizing core.

[0076] As a preferred option, such as Figure 15 As shown, the oil tank 91 is also provided with a base 97 that supports the liquid storage component 93. An air intake channel 98 that communicates with the atomizing hole is formed between the base 97 and the bottom of the oil tank 91. The support frame 204 is also provided with an air supply device 99. The air outlet of the air supply device 99 is connected to the air intake channel 98 and is used to provide upward blowing air to the atomizing hole to ensure that the smoke flows upward into the cavity 300.

[0077] In one embodiment, the heating element 96 is preferably made of metal felt, foam metal, heating cloth or mesh heating wire; the liquid storage element 93 and the liquid guide 95 are preferably made of cotton, which is non-conductive and allows both liquid and gas to flow inside.

[0078] In one embodiment, such as Figures 3 to 4As shown, the top of the transparent chamber 304 is detachably fitted with a top cover 400 that covers the cavity 300 via a snap-fit ​​mechanism. A smoke channel 302 is formed between the top of the guide section 305 and the top cover 400. The detachable top cover 400 exposes the internal mist inlet channel 301 after removal, allowing for the replenishment of liquid matrix for atomization after the liquid matrix within the atomizer has been completely atomized. This replenishment is typically done in small or measured amounts, and is generally not done in large quantities. It can exceed the absorption capacity of the liquid storage and guiding components, so an additional measuring cup can be provided to prevent the liquid matrix from overflowing and affecting the air intake of the air intake channel. When replenishing the liquid matrix, the flexible hose 307 with bends is used to make the liquid matrix flow downward along the wall of the flexible hose 307 and the air pipe 92, so that the liquid matrix eventually enters the air pipe and is absorbed by the guiding component and conducted to the liquid storage component, avoiding the liquid matrix falling directly vertically into the air intake channel without being absorbed by the guiding component and the liquid storage cotton.

[0079] In one embodiment, such as Figures 3 to 4 As shown, the inner side of the upper cover 400 is provided with a lamp plate 401 that illuminates the cavity 300.

The control board 7 can also be connected to the vehicle power supply and the vehicle central control screen to control the smoke backflow device. The guide section 305 is provided with two conductive posts 404 that are electrically connected to the control board 7. The conductive posts 404 and the control board 7 adopt a plug-in structure. The lamp panel 401 is provided with two conductive spring pins 405 that pass downward through the light guide cover 402 and abut against the conductive posts 404 one by one, so as to realize the electrical connection after the lamp panel is assembled.

[0081] In one embodiment, such as Figures 14 to 15 As shown, the support frame 204 is also provided with a second circuit board 407 that is electrically connected to the control board 7. The second circuit board 407 is electrically connected to the heating element 96 through a wire 408 passing through the air intake channel.

[0082] 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.

The middle of the guide plate 210 protrudes upward to form a guide section 305. A column 211 is placed in the middle of the guide section 305 and protrudes from the top of the hollow shell 200. A mist inlet channel 301 is provided in the middle of the column 211. The upper end of the hose 307 is connected to the bottom of the column 211, and the top of the column 211 protrudes out of the guide section 305. A surrounding space is formed between the guide plate 210 and the hollow shell 200 around the column 211. The air intake chamber 212 is provided, and the upper end of the guide section 305 is provided with an opening that surrounds the column 211 and communicates with the air intake chamber 212. The hollow shell 200 is also provided with a blower 213 that blows air toward the air intake chamber 212. The blower 213 is electrically connected to the control board 7. The blower 213 blows air into the air intake chamber 212 and blows the air out from the opening at the upper end of the guide section 305 to further disperse the smoke flowing out from the fog inlet channel and improve the downward flow of the smoke.

[0084] In another embodiment, such as Figures 1 to 4 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 22 and Figure 23 (As shown), this improves the aesthetics after installation.

[0085] In other embodiments, the exhaust device, smoke extraction device, blower, and air supply device are all preferably fans.
