Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a low-noise air purifier fan. Background Technology

[0002] An air purifier is a device that can adsorb, decompose, or transform air pollutants. It is mainly used to improve indoor air quality. It draws air into the machine through a fan and uses a built-in filter to filter the air, removing dust, odors, toxic gases, and some bacteria.

[0003] In a home environment, the user experience of an air purifier depends not only on its purification capabilities but also on noise control. Ordinary fans often generate significant noise during operation, which can disrupt the normal lives of family members. On quiet nights or during times when concentration is required, the noise is particularly noticeable, greatly affecting the user's comfort and experience.

[0004] Therefore, this utility model proposes a low-noise air purifier fan. Utility Model Content

[0005] The purpose of this invention is to provide a low-noise air purifier fan to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A low-noise air purifier fan includes a purifier housing, with several sets of air intake grilles on three of the four walls of the purifier housing. A purifier top cover is movably attached to the top of the purifier housing, and a fan body is disposed inside the purifier top cover. A motor is fixedly connected to the back of the fan body, and shock-absorbing devices are fixedly connected to all four walls of the fan body.

[0008] Furthermore, the four sets of shock absorption devices include two sets of hinge blocks. The outer walls of the two sets of hinge blocks are fixedly connected to the top cover of the purifier. One end of the transmission rod is hinged to the extended end of the hinge block. The other end of the two sets of transmission rods is hinged to both ends of the transmission rod. The transmission rod has two sets of circular holes inside. The inner wall of the circular holes may be fitted with a limit rod. The top end of the limit rod is fixedly connected to the outer wall of the fan body.

[0009] Furthermore, a spring is movably sleeved on the outer wall of the limiting rod, with one end of the spring fitting against the outer wall of the fan body and the other end fitting against the side of the transmission rod.

[0010] Furthermore, a damping shell is fixedly connected to the inner wall of the transmission rod two, a damping plate is movably sleeved on the inner wall of the damping shell, a transmission shaft is fixedly connected to the inner wall of the damping plate, the outer edge of the transmission shaft is fixedly connected to the outer wall of the fan body, and multiple sets of air passage holes are opened inside the damping plate.

[0011] Furthermore, a sound-absorbing cotton is fixedly connected to the top of the inner wall of the air purifier cover. The bottom end of the sound-absorbing cotton is aligned with the fan body, and the width of the sound-absorbing cotton is greater than that of the fan body.

[0012] Furthermore, the purifier housing is equipped with a purifier filter and a main body, the top of which is aligned with the fan body.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. When the air purifier is running, the motor drives the fan body to rotate. When the fan body vibrates, the vibration pushes the limit rod to slide inside the transmission rod two. The spring sleeved on the outer wall of the limit rod absorbs the vibration and cancels it out to maintain the stability of the fan body. At the same time, the fan body pushes the damping plate to slide inside the damping shell through the transmission shaft. The damping plate compresses the air inside the damping shell, absorbing the vibration and quickly attenuating it. The vibration is confined to a certain range and cannot be transmitted to the shell, avoiding resonance, reducing mechanical noise, making the purifier run more quietly, reducing interference with the user's daily life, extending the service life of the fan and shell, improving the stability and reliability of the equipment, and creating a quieter and more comfortable living environment for the user.

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1 to 5 As shown, the low-noise air purifier fan provided by this utility model includes a purifier housing 1, with several sets of air intake grilles 3 on three of the four walls of the purifier housing 1, a purifier top cover 2 movably attached to the top of the purifier housing 1, a fan body 11 disposed inside the purifier top cover 2, a motor 13 fixedly connected to the back of the fan body 11, and shock absorption devices fixedly connected to all four walls of the fan body 11.

[0026] The four sets of shock absorption devices include two sets of hinge blocks 5. The outer walls of the two sets of hinge blocks 5 are fixedly connected to the top cover 2 of the purifier. One end of the transmission rod 6 is hinged to the extended end of the hinge block 5. The other ends of the two sets of transmission rods 6 are hinged to both ends of the transmission rod 7. Two sets of round holes are opened inside the transmission rod 7. The inner wall of the round holes is fitted with a limit rod 8. The top end of the limit rod 8 is fixedly connected to the outer wall of the fan body 11.

[0027] A spring 9 is movably sleeved on the outer wall of the limiting rod 8. One end of the spring 9 is in contact with the outer wall of the fan body 11, and the other end of the spring 9 is in contact with the side of the transmission rod 7.

[0028] When the motor 13 starts, it drives the fan blades inside the fan body 11 to rotate. As the fan blades rotate, vibration is inevitable. The fan body 11 pushes the limit rod 8 to slide inside the transmission rod 7. The outer wall of the limit rod 8 is fitted with springs 9. These springs 9 can effectively absorb vibration energy and cancel each other out through their own elasticity, thereby maintaining the stability of the fan body 11. When the vibration of the fan body 11 causes it to deviate, the fluctuation of the transmission rod 7 will be further canceled out by the mutual movement of the two sets of transmission rods 6, ensuring that the vibration is not transmitted to the external purifier top cover 2, thereby avoiding noise caused by vibration and keeping the air purifier quiet during operation, providing users with a quiet environment.

[0029] A damping housing 14 is fixedly connected to the inner wall of the transmission rod 2 7. A damping plate 16 is movably sleeved on the inner wall of the damping housing 14. A transmission shaft 15 is fixedly connected to the inner wall of the damping plate 16. The outer edge of the transmission shaft 15 is fixedly connected to the outer wall of the fan body 11. Multiple sets of air passage holes are opened inside the damping plate 16.

[0030] Meanwhile, a damping housing 14 is provided between the transmission rod 7 and the fan body 11. When the fan body 11 vibrates due to the rotation of the fan blades, these vibrations will drive the transmission shaft 15, which in turn will drive the damping plate 16 to slide inside the damping housing 14. As the damping plate 16 slides, the air inside the damping housing 14 is compressed, forming a certain resistance. The air resistance can absorb the vibration energy and further reduce the amplitude of the vibration, so that the fan body 11 can always remain stable during operation, avoiding resonance and noise problems caused by vibration.

[0031] Example 2

[0032] Based on Example 1, please refer to Figures 1 to 4 As shown, a sound-absorbing cotton 10 is fixedly connected to the top of the inner wall of the air purifier top cover 2. The bottom end of the sound-absorbing cotton 10 is aligned with the fan body 11, and the width of the sound-absorbing cotton 10 is greater than that of the fan body 11.

[0033] A sound-absorbing cotton 10 is installed on the top of the back of the air purifier cover 2, corresponding to the top of the fan body 11. The sound-absorbing cotton 10 is made of a soft material with excellent sound absorption properties, which can effectively absorb and reduce the transmission of sound. When the fan body 11 collides with the sound-absorbing cotton 10 due to excessive vibration during operation, the sound-absorbing cotton 10, with its soft properties, can buffer and absorb the impact force generated by the collision, thereby reducing the additional noise generated by the collision. At the same time, the sound-absorbing cotton 10 can also absorb and isolate the noise generated by the fan body 11 itself during operation, further reducing the transmission of noise.

[0034] The air purifier housing 1 is equipped with an air purifier filter and a main body 4. The top of the air purifier filter and the main body 4 are aligned with the fan body 11.

[0035] By placing the purifier's filter and main body 4 at the bottom of the fan body 11, the filtered clean air can be discharged quickly and efficiently.

[0036] The top of the air purifier cover 2 has an air outlet slot 12, the width of which is the same as that of the fan body 11.

[0037] The air outlet slot 12 is aligned with the fan body 11, allowing air to enter the fan more smoothly through the grille, reducing airflow turbulence and eddy current generation. This helps improve airflow efficiency and ensures that the fan can achieve higher airflow with less energy consumption.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
