Description

Technical Field

[0001] This invention relates to a car fragrance diffuser, and more particularly to a car fragrance diffuser with a rope wheel mechanism for switching fragrances. Background Technology

[0002] Most mainstream car air fresheners come with multiple fragrance sticks of different scents, allowing users to switch between different scents each time. The original solution for releasing a specific fragrance was to install a fan at the bottom of each fragrance stick; the fan at the bottom of the corresponding fragrance stick would be activated when the desired scent was selected.

[0003] This solution requires as many fans as there are fragrance sticks, directly increasing costs. However, due to space constraints, each fan's power cannot be very high, resulting in lower airflow speed and affecting fragrance diffusion efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a car air freshener with a rope wheel mechanism for switching fragrances, which can meet the fragrance needs of different fragrance sticks with only one fan.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car fragrance diffuser with a rope-wheel mechanism for switching fragrances, comprising a housing, several chambers within the housing, each chamber containing a fragrance stick, a fan, and a drive mechanism for moving the fan. The drive mechanism includes a motor fixed to a sliding plate bracket, a roller mounted on the motor's output shaft, guide wheels at both ends of the sliding plate bracket, a pull rope wound around the roller, and both ends of the pull rope fitted onto the guide wheels. The fan is slidably connected to the sliding plate bracket and fixed to the pull rope. In use, the motor starts, driving the pull rope to rotate, which in turn moves the fan on the sliding plate bracket. When a specific fragrance is desired, the fan is moved under the fragrance stick of that fragrance and then activated, thus blowing out the fragrance. This method uses a single fan to meet the fragrance needs of different fragrance sticks. Furthermore, because there is only one fan, installation space is no longer limited, and the fan power can be made larger.

[0006] In a preferred embodiment of the present invention, a sealing device is further included. The sealing device comprises a main control board and a top cover bracket. The main control board is in close contact with the bottom of the chamber. An arc-shaped groove communicating with the chamber is provided on the main control board. An air guide plate is provided below the main control board, and a ventilation groove communicating with the arc-shaped groove is provided on the air guide plate. An air guide spherical surface is provided on the inner side of the ventilation groove. The top cover bracket is disposed between the slide bracket and the main control board. The top cover bracket has multiple sliding grooves, each corresponding to one air guide spherical surface. A through hole is provided at the bottom of each sliding groove. Two sealing plates are disposed in each sliding groove. The two sealing plates clamp the air guide spherical surface under the action of a compression spring, and the sealing plates block the ventilation groove. For fragrance sticks that do not require fragrance output, the chamber is sealed by the sealing plates, thus preventing cross-contamination of odors.

[0007] In a preferred embodiment of the present invention, one end of the sealing plate extends out of the upper cover bracket, and a guide rod is provided on the end of the sealing plate extending out of the upper cover bracket. A push rod is provided on the top of the fan. When the fan slides below the corresponding through hole, the push rod pushes the guide rod, causing the sealing plate to move outward against the elasticity of the compression spring, exposing the ventilation slot. The fan and the ventilation slot are connected. With this structure, the chamber of the fragrance stick will only open when the fan moves to the bottom of the fragrance stick, thus preventing cross-contamination of fragrance sticks.

[0008] In a preferred embodiment of the present invention, each sealing plate is provided with two guide rods, each guide rod having an inwardly extending first guide surface and the push rod having an outwardly protruding second guide surface.

[0009] In a preferred embodiment of the present invention, the skateboard bracket includes a hollow plate with grooves at both ends, and the two ends of the fan are slidably connected within the grooves.

[0010] In a preferred embodiment of the present invention, the outer shell includes an upper cover plate and a base, the upper cover plate is fixed on the base, and the chamber is disposed inside the upper cover plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Fragrance changing method: A single fan moves inside the device using an innovative rope wheel transmission structure. Different positions correspond to different fragrances, thus realizing the fragrance switching function.

[0012] 2. Cost advantage: Through innovative structural design, the original three fans are reduced to a single fan, significantly reducing the overall cost while ensuring functionality.

[0013] 3. Storage method: Through innovative structural design, the three chambers for storing the fragrance stick can be individually sealed, and only one chamber can be opened to release the fragrance while the other two chambers remain sealed, thus avoiding the problem of mixed fragrances inside the fragrance diffuser.

[0023] Please see Figure 1-7 This invention provides a technical solution: a car air freshener with a rope wheel mechanism for switching fragrances, comprising a housing 1, wherein the housing 1 has three chambers 1a, the housing 1 includes an upper cover plate 11 and a base 12, the upper cover plate 11 is fixed to the base 12, and the chambers 1a are disposed within the upper cover plate 11. Each chamber 1a contains a fragrance stick 2.

[0024] It also includes a fan 3 and a drive mechanism 4 for driving the fan to move. The drive mechanism 4 includes a motor 41, which is fixed to the skateboard bracket 5. The skateboard bracket 5 includes a hollow plate 51, with slide rails 52 at both ends of the plate 51.

[0025] A roller 42 is mounted on the output shaft of the motor 41. Guide wheels 53 are mounted on both ends of the slide bracket 5. A pull rope 43 is wound around the roller 42, and both ends of the pull rope 43 are fitted onto the guide wheels 53. The fan 3 is slidably connected to the slide bracket 5; specifically, both ends of the fan 3 are slidably connected within the slide rail 52. The fan 3 is fixed to the pull rope 43.

[0026] It also includes a sealing device 6, which includes a main control board 61 and an upper cover bracket 62. The main control board 61 is in close contact with the bottom of the chamber 1a, and the main control board 61 is provided with an arc-shaped groove 611 that communicates with the chamber 1a.

[0027] Below the main control board 61, there is an air guide plate 7. The air guide plate 7 is provided with a ventilation groove 71 that communicates with the arc-shaped groove 611. The inner side of the ventilation groove 71 is provided with an air guide spherical surface 72.

[0028] The upper cover bracket 62 is disposed between the slide plate bracket 5 and the main control board 61. The upper cover bracket 62 is provided with three slide grooves 621, each slide groove 621 corresponding to one of the air guide spherical surfaces 72. The bottom of the slide groove 621 is provided with a through hole 622.

[0029] Each of the slide grooves 621 is provided with two sealing plates 63. The two sealing plates 63 clamp the air guide ball surface 72 under the action of the compression spring 64, and the sealing plates 63 block the ventilation groove 71. For fragrance sticks that do not need to emit fragrance, the chamber is sealed by the sealing plates, which can prevent cross-contamination of odors.
