Description

[Technical Field]

[0001] The present invention relates to an automobile air freshener diffuser (hereinafter referred to as "diffuser") for use with air fresheners in automobiles. [Background technology]

[0002] Conventionally, canned air fresheners have been used as a means of fragrance in cars. Canned air fresheners are packed with fragrance ingredients in gel or absorbent form inside a can container, and once opened, the scent is released by natural evaporation.

[0003] Such canned air fresheners have the advantage of being easy to use, since they can be used simply by removing the lid of the can and placing it on the dashboard or in a cup holder. However, because the scent is released through natural evaporation, it is not possible to control the diffusion range or diffusion speed, and the fragrance ingredients are consumed even when the car is not in use.

[0004] Against this background, diffusers have been developed that store canned air fresheners in a dedicated container and install an electric fan on top of the container to forcibly diffuse the air. This improves the diffusion performance of the fragrance ingredients and allows the scent to be released only when needed by controlling the electric fan, thereby achieving efficient use. Furthermore, by storing the air freshener in a dedicated container, the container becomes saturated with the fragrance ingredients when the vehicle is not in use, preventing further evaporation and reducing unnecessary consumption of the fragrance ingredients.

[0005] [Patent Document 1] Nothing in particular Summary of the Invention [Problem to be solved by the invention]

[0006] However, in conventional diffusers, the air intake is located near the bottom of the container. This type of diffuser container typically has a height that allows it to fit into a car's cup-shaped drink holder, so it can be used by placing it in the drink holder. However, in this case, the side wall of the drink holder can block the air intake, preventing sufficient air from being drawn in, resulting in reduced fragrance diffusion performance. Another drawback is that the drink holder is prone to sucking in dust and dirt.

[0007] The present invention was made in light of the problems with the prior art described above, and aims to provide a diffuser for canned air fresheners in automobiles that has good air intake efficiency and can fully diffuse the fragrance, even when the canned air freshener is placed in a cup-shaped drink holder inside the car.

[0008] In addition, taking into account the fact that can containers of different standards and height dimensions are circulating on the market, this device aims to increase versatility and improve user convenience by making it possible to stably store and support can containers of different heights. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the present invention provides a car air freshener diffuser for canned air fresheners, which comprises a cylindrical container with a bottom and a cover with a built-in electric fan, and a canned air freshener placed in the container. The cover has a contact portion located below the electric fan and against which the top end of the canned air freshener contacts. The cover also has an air intake and a fragrance release port, which are located at any position above the vertical position corresponding to the contact portion.

[0010] The car air freshener can diffuser of this invention has an air intake located anywhere above the vertical position of the abutment, so the air intake is not blocked by the side wall of the drink holder, allowing for stable air intake even when used inside the car. This improves the fragrance diffusion performance and allows the scent to fill the cabin efficiently. Furthermore, because the air intake is located away from the bottom, it is possible to reduce the intake of dust and dirt, making it more hygienic.

[0011] In addition, the car air freshener can diffuser according to the present invention may have an air intake located at any position below or directly beside the vertical position corresponding to the height of the electric fan, and the fragrance release outlet located above the vertical position corresponding to the height of the electric fan.

[0012] In the car air freshener can diffuser of this invention, which is configured in this way, the fragrance outlet is located above the electric fan, so the fragrance is efficiently diffused upward by the air blown by the electric fan, resulting in the scent reaching the user's sense of smell quickly.

[0013] Furthermore, the bottom of the car air freshener can diffuser according to the present invention may be a movable bottom that can move up and down independently of the barrel of the container, and a spring may be disposed on the underside of the movable bottom to urge the movable bottom upward.

[0014] The car air freshener diffuser of this invention is designed in this way so that the top of the can is securely held in contact with the abutment of the cover, even if the can is of different heights, preventing rattles and misalignment. This ensures versatility and allows it to accommodate a variety of cans. [Effects of the Invention]

[0015] The car air freshener diffuser of this invention features an air intake and a fragrance release port located above the height of the abutment corresponding to the top of the can. This allows for stable air intake without being blocked by side walls, even when the can is placed in a cup-shaped drink holder, ensuring efficient fragrance diffusion. Furthermore, the air intake port is located away from the bottom, minimizing the intake of dust and debris, ensuring excellent cleanliness. Furthermore, the fragrance release port is located above the electric fan, effectively diffusing the fragrance upward, ensuring rapid and sufficient delivery of the fragrance to the user. Furthermore, the diffuser's versatility allows it to accommodate different can container sizes, greatly improving user convenience. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Fig. 1 is a perspective view of the exterior of a canned car air freshener diffuser 100 (hereinafter referred to as diffuser 100) according to the present invention. As shown in Fig. 1, diffuser 100 comprises a cylindrical container 10 with a bottom and a cover 20 attached to the top of the container. Container 10 has a height dimension that allows it to be accommodated in a cup-type drink holder in a car.

[0018] Fig. 2 is a perspective view showing the state in which cover 20 is removed from car canned air freshener diffuser 100 of the present invention and can container C (canned air freshener) is inserted into container 10. As shown in Fig. 2, can container C is housed inside container 10. Can container C contains, for example, a gel-like air freshener, and is set in container 10 in an opened state.

[0019] Fig. 3 is an exploded perspective view showing the configuration of the diffuser 100. As shown in Fig. 3, a movable bottom 11 is disposed at the bottom of the container 10, and a spring 12 is interposed between this movable bottom 11 and the inner bottom 10c (shown in Fig. 4) of the container 10. The spring 12 biases the movable bottom 11 upward, thereby constantly pushing up the can container C set in the container 10.

[0020] The cover 20 is constructed by attaching a decorative ring 22 and a top decorative cover 23 to a cover base body 25. The cover 20 incorporates a functional unit for diffusing fragrance. Specifically, a circuit board 24 is mounted on the cover base body 25, forming the control center of the diffuser 100. The circuit board 24 is equipped with a fan control circuit (not shown) for controlling the electric fan 21, as well as LEDs (not shown) for decorative or functional indication, an LED control circuit (not shown) for controlling the LED, and switches 24a, 24a. A power cord 21a for the electric fan 21 is connected to the circuit board 24, and the operation of the electric fan 21 is controlled by this board. The circuit board 24 is also equipped with a USB-C interface, and is connected to an external power source such as the vehicle's accessory power supply via this interface. This allows the diffuser 100 to receive a stable power supply from the vehicle's onboard power source.

[0021] An upper decorative cover 23 on the upper surface of the cover 20 is provided with a switch button 23a for controlling the operation of the diffuser 100 and a lighting control button 23b for operating the lighting function. These buttons are configured to contact respective switches 24a, 24a mounted on a circuit board 24, thereby transmitting operation input to the circuit board.

[0022] FIG. 4 is a longitudinal cross-sectional view of the diffuser 100 taken along line II-II in FIG. 2. Note that FIG. 4 shows a state in which a can container C is not set. As shown in FIG. 4, the bottom of the container 10 is not integral with the cylindrical portion 10a of the container 10 but is composed of a movable bottom 11, which is an independent member. The movable bottom 11 is supported so as to be vertically movable relative to the cylindrical portion 10a of the container 10. A sliding cylinder 11b on the movable bottom side extending from the lower surface 11a of the movable bottom 11 and a sliding cylinder 10b on the container side extending from the inner bottom 10c of the container 10 overlap each other and are configured to slide vertically. A spring 12 is disposed inside these sliding cylinders 11b and 10b to constantly urge the movable bottom 11 upward. This pushes the movable bottom 11 upward, reliably supporting the can container C placed inside the container 10. In addition, the cover base body 25 of the cover 20 is provided with an abutment portion 20a, and when a can container C is set in the container 10, its upper edge abuts against the abutment portion 20a, thereby stably holding the can container C. When the can container C is pushed up by the movable bottom 11, its upper end abuts securely against the abutment portion 20a, preventing it from rattling due to the swaying of the vehicle and ensuring reliable positioning. Furthermore, even if the height dimensions of can containers vary, their upper ends are securely abutted against the abutment portion 20a of the cover to hold them in place, preventing rattling and misalignment. This ensures versatility that can accommodate a variety of can containers.

[0023] Furthermore, the top surface of cover 20 is provided with fragrance release port 20c for releasing fragrance through the gap formed between decorative ring 22 and top decorative cover 23. In this embodiment, fragrance release port 20c is located above the vertical position corresponding to the height position of abutting portion 20a and above the vertical position corresponding to the height position of electric fan 21. With fragrance release port 20c positioned in this manner, when electric fan 21 is driven with can container C set in place, the fragrance components rise due to the air blown by electric fan 21 and are efficiently diffused from fragrance release port 20c into the vehicle interior.

[0024] Air flow paths are defined inside cover 20, with air intake path IN being a path through which outside air is introduced from air intake port 20b, passes through air intake space S1 of cover base body 25, mixes with the fragrance rising from canister C, and reaches the intake side of electric fan 21, and fragrance emission path OUT is a path through which the fragrance passes through the exhaust side of electric fan 21, and is emitted from fragrance emission space S2 of cover base body 25 through fragrance emission port 20c into the vehicle cabin. In this embodiment, electric fan 21 is positioned so that it draws in outside air and fragrance from the lower side (canister C side) and exhausts them upward.

[0025] This embodiment enables stable intake of air and efficient fragrance diffusion inside a vehicle. This ensures sufficient diffusion even when the device is placed in a drink holder, and also prevents dirt and dust from being sucked in near the bottom, ensuring excellent cleanliness.
