Description

Technical Field

[0001] This utility model relates to the field of aroma diffuser technology, specifically to an aroma diffuser for use in vehicles with a unique mist output method. Background Technology

[0002] Currently, in order to make the scent inside the car more suitable for the needs of the passengers, some car owners place air fresheners that can release fragrance in the car. These air fresheners include an oil-filled cotton that produces fragrance and a heating wire that heats the liquid in the oil-filled cotton to atomize it. The heating wire is connected to a circuit board inside the air freshener. When in use, the air freshener is turned on, and the heated wire blows out through a fan set inside the air freshener. Because the atomized fragrance is blown out at the right time after heating, the amount of fragrance is small, the concentration is low, and it is not well-formed, so it lacks visual appeal.

[0014] Technical Effects: The aroma diffuser of this invention uses an atomizing component to heat and atomize the vapor, which is then stored in a mist storage chamber. After a set storage time, the air supply component is activated, generating airflow through a turbine fan. Simultaneously, the valve component opens, and the airflow enters the mist storage chamber through a duct consisting of a lower, middle, and upper air duct, agitating the vapor inside and causing it to be evenly blown out from the mist outlet in the upper shell component. Because the valve component opens after a set time, when the valve component is not open, the atomized aroma is stored in the mist storage chamber, allowing the rich, swirling aroma to be viewed through the transparent top cover. After the valve component opens, the air supply component blows out all the aroma stored in the mist storage chamber, resulting in a rich and visually appealing mist. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-3 As shown, this utility model embodiment provides a car air freshener, including: a bottom shell assembly 10, an upper shell assembly 20 disposed thereon, an atomizing assembly 30, and a PCB board 40 disposed inside the bottom shell assembly. The upper shell assembly has a mist outlet 202. It also includes: a mist storage chamber 201 disposed inside the upper shell assembly and communicating with the outlet of the atomizing assembly, an air supply assembly 50 disposed inside the bottom shell assembly and communicating with the mist storage chamber, and a valve assembly 60 disposed inside the bottom shell assembly for controlling the air duct opening and closing between the mist storage chamber and the air supply assembly.

[0028] like Figures 3-10As shown, the bottom shell assembly 10 includes: a bottom shell 101 with an opening at the lower end and a top cover plate 101a at the upper end; a bottom cover 102 connected to the lower end of the bottom shell; a mounting ring 103 disposed on the inner bottom surface of the bottom cover and a first lower air duct 104 communicating with it; a first notch 104a disposed in one side plate of the first lower air duct; and an upper air duct 105 connected to the bottom shell 101, with its upper end passing through the top cover plate and located in the mist storage chamber 201 and its lower end located in the bottom shell. The bottom shell assembly contains an audio module 140 and a button 150 mounted on the inner wall of the bottom shell 101 and electrically connected to the PCB board 40; a charging interface 160 disposed on the PCB board 40; and a battery 170 disposed on the bottom cover 102 and connected to the PCB board 40.

[0029] For installing components such as the air supply assembly 50 and valve assembly 60, an installation assembly 70 is also included, which includes: an installation plate 701; an upper ring 702 disposed on the bottom surface of the installation plate and having the same shape as the installation ring 103; an air duct cover 703 disposed on the bottom surface of the installation plate and having the same shape as the first lower air duct 104; and a middle air duct 704 disposed on the upper surface of the installation plate, with its lower end connected to the air duct cover and its upper end connected to the lower end of the upper air duct 105; the installation ring 103 and the upper ring 702, when combined, form a closed system. The installation space, i.e., the upper ring body is equivalent to the upper cover that closes the opening of the installation ring body; the first lower air duct 104 and the air duct cover 703 are combined to form a lower air duct that communicates with the installation space; the bottom surface of the mounting plate 701 is provided with a guide strip 705 located between the upper ring body 702 and the air duct cover 703 to isolate the communication between the two; here, the installation space and the lower air duct are connected through the first notch 104a; the upper air duct 105, the middle air duct 704 and the lower air duct constitute an air duct that connects the installation space and the mist storage chamber 201.

[0030] like Figure 3 As shown, the air supply assembly 50 includes: an air supply motor 501 disposed on the upper surface of the mounting plate 701 and electrically connected to the PCB board 40, and a turbine fan 502 disposed in the mounting space; the output shaft of the air supply motor extends into the mounting space and is connected to the turbine fan. When the air supply motor 501 is started, it drives the turbine fan 502 to rotate in the mounting space, sending airflow into the mist storage chamber 201 through the air duct.

[0031] like Figure 3As shown, the valve assembly 60 includes: a valve motor 601 mounted on the upper surface of the mounting plate 701 and electrically connected to the PCB board 40; a drive gear 602 located on the bottom surface of the mounting plate and connected to the output shaft of the valve motor; a large driven gear 603 located on the bottom surface of the mounting plate and meshing with the drive gear; a small driven gear 604 located on the large driven gear and coaxially arranged with it; a rack 605 located on the inner bottom surface of the bottom cover 102 and meshing with the small driven gear; and a valve stem 606 located at one end of the rack. When the valve stem moves along the guide bar 705 following the rack, it extends into or out of the first downdraft duct 104 through the first notch 104a, and, in conjunction with the guide bar 705, opens or closes the connection between the downdraft duct and the installation space. However, when air needs to be supplied into the mist storage chamber 201, the valve motor 601 starts, driving the drive gear 602 to rotate. The large driven gear 603 and the small driven gear 604 rotate accordingly, driving the rack 605 to translate along the guide bar 705. The valve stem 606 translates accordingly, allowing the valve stem to exit the first lower air duct 104 through the first notch 104a, thus connecting the installation space with the air duct. Conversely, the valve stem 606 extends into the first lower air duct 104 through the first notch 104a, cutting off the connection between the installation space and the air duct. Here, after the valve stem 606 enters the first lower air duct, it engages with the guide bar 705, cutting off the connection between the installation space and the air duct. The upper surfaces of the rack 605 and the valve stem 606 are provided with guide grooves 607 that are interconnected and movably connected to the guide bar 705; the bottom surface of the bottom cover 102 is provided with a gear protection frame 608 for installing the small driven gear 604. Here, the start interval of the valve motor 601 can be set through the PCB board 40, thereby controlling the opening interval of the valve assembly 60. For example, if the set interval is 20 seconds, the valve will open once every 20 seconds, and the air supply assembly will open synchronously. Controlling the opening and closing of electronic components through circuits is existing technology and will not be elaborated here.

[0032] like Figure 5 As shown, the upper shell assembly 20 includes: an upper shell 203 disposed on the bottom shell assembly 10, and an upper cover 204 disposed at the upper end of the upper shell and closing the opening; the mist storage chamber 201 is located in the space formed by the combination of the upper shell and the upper cover; the mist outlet is disposed in the upper cover; a recessed hole 204a is provided in the upper surface of the upper cover; the upper shell is provided with an upper through hole 203a communicating with the outlet of the atomizing component; the upper cover 204 is made of transparent material so as to view the scented mist stored in the mist storage chamber 201.

[0033] An LED light board 80 electrically connected to the PCB board 40 and a solar panel 90 located above the LED light board are provided inside the recessed hole 204a; a protective cover 100 for protecting the solar panel is provided at the opening of the recessed hole; both the protective cover and the recessed hole are circular and there is a gap between their outer walls and the inner wall at the opening of the recessed hole so that the mist can flow out from the gap; there are several mist outlet holes 202 and they are all located inside the inner wall of the recessed hole 204a, that is, there are several mist outlet holes inside the inner wall of the recessed hole so that the mist stored in the mist storage chamber 201 can flow out evenly from the several mist outlet holes 202 under the blowing of the air supply component 50.

[0034] like Figure 3 As shown, for the installation of the atomizing assembly 30, the bottom shell 101 has an installation cylinder 101b with an upper opening connected to the top cover plate 101a. The atomizing assembly 30 includes a consumable shell 301 installed inside the installation cylinder with its upper opening located above the top cover plate, a columnar oil-collecting cotton 303 disposed inside the consumable shell, a heating wire 304 disposed axially within the columnar oil-collecting cotton and electrically connected to the PCB board 40, an upper silicone plug 305 disposed inside the upper opening of the consumable shell, a consumable top cover 306 at the upper opening, and a lower silicone plug 307 disposed at the bottom of the consumable shell. The consumable top cover is located above the upper silicone plug, and both have a mist outlet perforation 308 serving as the outlet of the atomizing assembly. The heating wire 304 heats the oil in the oil-collecting cotton, atomizing it, and storing it in the mist storage chamber 201 through the mist outlet perforation 308.

[0035] like Figure 3 As shown, the bottom shell 101 has three mounting cylinders 101c whose upper ends are fixedly connected to the bottom surface of the top cover plate 101a. Each mounting cylinder has a columnar magnet 101d. The upper surface of the top cover plate 101a has a ring-shaped fixing plate 110 that attracts the columnar magnet and is fixedly connected to the upper shell assembly 20. The ring-shaped fixing plate is sleeved on the outside of the atomizing assembly 30. The upper shell 203 has an upper mounting cylinder 203b coaxial with it at the axial through hole. The upper mounting cylinder is sleeved on the outside of the consumable cover 306. Therefore, the ring-shaped fixing plate 110 is sleeved on the outside of the upper mounting cylinder and the upper end of the consumable shell 301, that is, the ring-shaped fixing plate is indirectly sleeved on the outside of the atomizing assembly 30. The upper surface of the ring-shaped fixing plate has a ejector pin bracket 120. The PCB board 40 has an ejector pin 130 whose upper end is connected to the ejector pin bracket.

[0036] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.
