Description

Technical Field

[0001] This utility model relates to the field of automotive seat fan technology, and in particular to an integrated blowing and suction automotive seat fan structure. Background Technology

[0002] Current car seat ventilation systems only offer a single blowing or suction mode. It's impossible for the same seat to simultaneously implement both modes. Under the same environmental conditions, the blowing mode cools the seat faster than the suction mode. Furthermore, in terms of sensory comfort, the suction mode is more comfortable than the blowing mode during prolonged exposure to seat ventilation. Therefore, this invention addresses these issues by providing a structural control device that can simultaneously implement both blowing and suction modes.

[0003] In the existing technology, one fan per seat cushion can only achieve one ventilation mode; and if two ventilation modes are required on one seat cushion, two fans are needed. The traditional control method has the following disadvantages: when two ventilation modes are required, two fans are needed, which requires more installation space. The one-to-one control method cannot be installed in equipment with small space requirements; it occupies a lot of space; installation is inconvenient, and production and assembly also consume more time. Utility Model Content

[0004] The purpose of this utility model is to provide a blower structure for car seats that integrates blowing and suction, which solves the problems of requiring more installation space, the inability of one-to-one control method to be installed in equipment with smaller space requirements, and large space occupation.

[0005] To achieve the above objectives, a combined blowing and suction car seat fan structure is provided, comprising: an air guide shroud, a blower fixedly connected inside the air guide shroud, an air inlet on one side of the blower, an air outlet at the output end of the blower, a plurality of ball bearings rotatably fitted on the inner wall of the output end of the air outlet, a guide shaft rotatably connected inside the ball bearings, an air inlet duct on one side of the guide shaft, an air outlet duct on the other side of the guide shaft, a seat air bag fixing interface rotatably connected to the end of the guide shaft away from the air guide shroud, a car seat air duct fixedly connected to one end of the seat air bag fixing interface, a drive motor fixedly connected to the outside of one side of the air guide shroud, a drive gear fixedly connected to the drive end of the drive motor, and a driven gear meshing on one side of the drive gear.

[0006] According to the aforementioned integrated blowing and suction car seat fan structure, mounting blocks are fixedly connected to the outer sides of both the air guide cover and the drive motor, and a protective cover is attached to one side of the mounting block.

[0007] According to the aforementioned integrated blowing and suction automotive seat fan structure, the protective cover is fitted over the drive gear and the driven gear.

[0008] According to the aforementioned integrated blowing and suction automotive seat fan structure, the protective cover and the mounting block are threadedly connected by mounting bolts.

[0009] According to the aforementioned integrated blowing and suction automotive seat fan structure, the interior of the passive gear is fixedly connected to the air guide shaft.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] This utility model, by incorporating an air guide hood and a blower, achieves two ventilation effects through a single blower structure, providing a more comfortable experience. When the temperature is high, the blowing mode can be activated for faster cooling; when the temperature reaches a comfortable level, it can be switched to suction mode for a more natural and comfortable temperature maintenance effect. It is low-cost, easy to operate, and improves portability.

[0023] Reference Figure 1-6 This utility model discloses a blower structure for an integrated car seat fan, comprising: an air guide hood 2, with a blower 6 fixedly connected inside the air guide hood 2. When the blower 6 is activated, it draws external air from an air inlet 1 on one side into the blower 6. An air inlet 1 is provided on one side of the blower 6, and an air outlet 7 is provided at the output end of the blower 6. Air is discharged through the air outlet 7 and flows through the air outlet duct 11 to the seat air bag fixing interface 4, thus blowing the air outward and achieving the effect of blowing air out of the seat. Several ball bearings 3 are rotatably fitted on the inner wall of the output end of the air outlet 7. A guide shaft 5 is rotatably connected inside the ball bearings 3. An air inlet duct 12 is provided on one side of the guide shaft 5, and an air outlet duct 11 is provided on the other side of the guide shaft 5, guiding the air from the seat air bag fixing interface 4 into the air inlet 12. The air vent 1 enters the blower 6 from one side and is discharged through the air inlet duct 12 on the other side, thereby achieving the switching of gas flow and completing the integrated suction and blowing function. The end of the air guide shaft 5 away from the air guide cover 2 is rotatably connected to the seat air bag fixing interface 4. It is installed in the seat where ventilation needs to be controlled through the structure of the air guide cover 2, and then connected to the ventilation duct in the seat through the seat air bag fixing interface 4. One end of the seat air bag fixing interface 4 is fixedly connected to the car seat air duct. The drive motor 8 is fixedly connected to the outside of one side of the air guide cover 2. By driving the drive motor 8, the drive gear 9 is rotated. After rotation, it meshes with the driven gear 10. The rotation of the driven gear 10 drives the rotation of the air guide shaft 5. The drive end of the drive motor 8 is fixedly connected to the drive gear 9, and the driven gear 10 is meshed on one side of the drive gear 9.

[0024] Mounting blocks are fixedly connected to the outer sides of both the air guide shroud 2 and the drive motor 8. A protective cover 13 is attached to one side of the mounting block. During use, the protective cover 13 is fitted over the outside of the drive gear 9 and the driven gear 10 to prevent impurities from affecting the meshing of the gears during the gas blowing process. The protective cover 13 is fitted over the outside of the drive gear 9 and the driven gear 10. A mounting bolt 14 is threadedly connected between the protective cover 13 and the mounting block. The inside of the driven gear 10 is fixedly connected to the air guide shaft 5.

[0025] Working principle: In use, the system is first installed at the location on the seat requiring ventilation control via the air guide shroud 2. Then, it connects to the ventilation duct in the seat via the seat air bag fixing interface 4. After connection, the blower 6 starts, drawing external air from the air inlet 1 on one side into the blower 6, which then exhausts the air through the air outlet 7. The air then flows through the air outlet 11 to the seat air bag fixing interface 4, completing the outward blowing of air from the seat. When switching to seat suction, the drive motor 8 is activated. This drives the drive gear 9, which meshes with the driven gear 10. The rotation of the driven gear 10 drives the rotation of the air guide shaft 5. Both ends of the air direction shaft 5 are connected by ball bearings 3, which can maintain stable rotation for switching. After rotation, the air outlet duct 11 rotates to one side of the air inlet duct 12, and the air inlet duct 12 rotates to one side of the air outlet duct 11. At this time, the seat air bag fixing interface 4 is in the air inlet, driven by the blower 6. After driving, the gas from the seat air bag fixing interface 4 is guided into one side of the air inlet 1 and into the interior of the blower 6, and then discharged through the air inlet duct 12 on the other side, thereby realizing the switching of gas flow and completing the integrated suction and blowing function. In addition, during use, the protective cover 13 is fitted on the outside of the drive gear 9 and the driven gear 10 to prevent impurities from affecting the meshing of the gears during the gas blowing process.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
