The housing includes a detachably connected upper housing and a lower housing. The upper housing and the lower housing are joined to form an accommodating space. The fan motor assembly and the fan blade assembly are installed within the accommodating space. An air outlet is formed at the connection between the upper housing and the lower housing. The upper housing extends downward from the air outlet to abut against the lower housing, forming a noise reduction section. An air inlet is formed on the surface of the upper housing. This low-noise car seat fan effectively reduces wind noise by adding a deflector, greatly improving passenger comfort.

[0004] However, the above technical solutions still have the following shortcomings: If the air inlet is not dustproofed during the use of the fan, dust will enter the fan. Over time, too much dust and other debris will accumulate inside the fan. When the fan rotates, it will come into contact with the debris and collide with it, making noise. Furthermore, the long-term accumulation of dust on the fan will reduce its lifespan.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1 - Figure 4 A low-noise car seat fan in this embodiment includes a fan body 1, an air inlet 2 on the top of the fan body 1, an air outlet 3 on the side of the fan body 1, a collar 4 on the top of the fan body 1, a dustproof mechanism provided by the collar 4, a limiting plate 11 fixedly connected inside the air outlet 3, and an adjustment component provided by the limiting plate 11. The dustproof mechanism includes a dustproof ventilation plate 5 set above the collar 4, several ventilation holes 6 are provided around the collar 4, a connecting plate 7 is provided on the side of the collar 4, and a sleeve 8 is provided on the top of the fan body 1. The adjustment assembly includes a baffle plate 13 disposed inside the limiting plate 11, and a guide rail 12 disposed on the inner bottom wall of the air outlet 3. When the fan body 1 is working, it is started. At this time, the fan body 1 will take in air through the air inlet 2 and then blow the air out through the air outlet 3 to cool the seat. At this time, the air will enter the air inlet 2 through the ventilation holes 6 on the dustproof ventilation plate 5 and the collar 4. Dust and other debris will be blocked on the dustproof ventilation plate 5 and the collar 4. When the dustproof ventilation plate 5 and the collar 4 are blocked, press the two irregular connecting rods 9 to bring them closer together. At this time, the collar 4 can be removed for cleaning through the dustproof mechanism. When it is necessary to adjust the size of the air outlet 3 of the fan body 1, the motor 15 is started. The motor 15 will drive the threaded rod 14 to rotate. Under the action of the adjustment component, the baffle plate 13 will move to adjust the size of the air outlet 3 to adapt to different air volumes. In addition, adjusting the size of the air outlet 3 according to the air volume helps to reduce noise. At this time, the fan body 1 is treated with dustproofing to prevent dust from entering the fan body 1 and damaging the fan. In addition, reducing the entry of dust into the fan body 1 will reduce the noise generated and improve the noise reduction effect. At the same time, it reduces the friction and collision between the fan and dust inside the fan body 1, and improves the service life of the fan body 1.

[0020] The dustproof mechanism also includes irregularly shaped connecting rods 9 arranged on opposite sides of the connecting plate 7, and a spring 10 is provided inside the connecting plate 7; The bottom of the dustproof ventilation plate 5 is fixedly connected to the top of the collar 4. The collar 4 is located above the air inlet 2. One side of the connecting plate 7 is fixedly connected to the side of the collar 4. The bottom of the sleeve 8 is fixedly connected to the top of the fan body 1, and the two irregular connecting rods 9 extend into the connecting plate 7 at their close ends, and the irregular connecting rods 9 are slidably connected to the connecting plate 7. The ends of the two irregularly shaped connecting rods 9 that are far apart from each other both penetrate the inner wall of the sleeve 8. The irregularly shaped connecting rods 9 are slidably connected to the sleeve 8. The two opposite ends of the spring 10 are respectively fixedly connected to the ends of the two irregularly shaped connecting rods 9 that are close to each other. Please refer to Figure 1 , Figure 2 and Figure 4When cleaning the collar 4 is required, first, press the two irregularly shaped connecting rods 9 closer together. At this time, the two irregularly shaped connecting rods 9 will slide inside the connecting plate 7, and the other end of the irregularly shaped connecting rods 9 will leave the sleeve 8. Then, the collar 4 can be removed for cleaning. After cleaning, place the collar 4 over the air inlet 2, with the bottom of the irregularly shaped connecting rods 9 facing the top of the sleeve 8. Then, press the two irregularly shaped connecting rods 9 to slide closer together inside the connecting plate 7. As the two irregularly shaped connecting rods 9 move closer together... Spring 10 will gradually be in a compressed state. After the two irregular connecting rods 9 are retracted into the connecting plate 7, the collar 4 is then inserted downwards. At this time, the bottom of the irregular connecting rod 9 will extend into the sleeve 8. After one end of the irregular connecting rod 9 is aligned with the fixed position on the sleeve 8, the irregular connecting rod 9 is released. At this time, spring 10 will lose its compressive force and begin to reset. Under the reset action of spring 10, the two irregular connecting rods 9 will move away from each other until they are inserted into the sleeve 8, thus fixing the position of the fan body 1 and the collar 4. At this time, the collar 4 and the dustproof ventilation plate 5 were easily and quickly disassembled, which improved the efficiency of cleaning and allowed the fan body 1 to enter the working state as soon as possible.

[0021] The adjustment assembly also includes a threaded rod 14 disposed on the side of the fan body 1, a motor 15 for driving the threaded rod 14 is disposed on the side of the threaded rod 14, the bottom of the guide rail 12 is fixedly connected to the inner bottom wall of the air outlet 3, and the bottom of the baffle plate 13 is slidably connected to the top of the guide rail 12. The baffle plate 13 is slidably connected to the limiting plate 11. One end of the threaded rod 14 passes through the side of the fan body 1 and is rotatably connected to the fan body 1. One end of the threaded rod 14 passes through the side of the limiting plate 11 and is rotatably connected to the limiting plate 11. One end of the threaded rod 14 passes through the baffle plate 13 and is threadedly connected to the baffle plate 13. The other end of the threaded rod 14 is fixedly connected to the output end of the motor 15. Please refer to Figure 1 , Figure 2 and Figure 3 When adjusting the size of the air outlet 3, firstly, start the motor 15. At this time, the motor 15 will drive the threaded rod 14 to rotate. As the threaded rod 14 rotates, the baffle plate 13 will slide on the guide rail 12 under the limiting action of the guide rail 12 and the limiting plate 11 to adjust its position. At this time, the baffle plate 13 and the limiting plate 11 will adjust the size of the air outlet 3 so that the size of the air outlet 3 can be adapted to the air volume of the fan body 1, improve the flexibility of the device, reduce the noise caused by the mismatch between the wind speed and the air outlet 3, and improve the noise reduction effect of the device. At this time, the size of the air outlet 3 was adjusted so that the air outlet 3 can be flexibly adjusted according to the air volume of the fan body 1, reducing the noise caused by the mismatch between the wind speed and the air outlet 3.

[0022] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections. Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.
