Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to a noise reduction mechanism for air purification equipment. Background Technology

[0002] With the improvement of people's living standards and increased attention to the quality of their living environment, air purification equipment is being used more and more widely in daily life. Its main function is to remove pollutants such as dust, pollen, bacteria, viruses, and harmful gases from the air through filtration, adsorption, and decomposition, creating a healthier and fresher breathing environment for people. It plays an important role in various places such as homes, offices, hospitals, and schools. However, noise has become one of the key factors affecting user experience during the operation of air purification equipment.

[0003] Currently, existing air purification equipment has been found to have at least the following technical problems in actual use;

[0004] Most existing air purification devices do not have noise reduction structures. During operation, the high-speed friction between the blades and the air generates aerodynamic noise. Furthermore, as the air flows, it comes into contact with the air ducts and filters of the purification device, creating turbulence and eddies, which in turn generate noise. This noise can affect and interfere with users' daily lives, impacting work efficiency and mental health. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a noise reduction mechanism for air purification equipment, solving the problem that existing air purification equipment does not have a noise reduction structure, which affects users' work efficiency and mental health.

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

[0007] A noise reduction mechanism for an air purification device includes a purification cylinder. A fan assembly is fixedly connected to the top surface of the purification cylinder. The fan assembly includes a mounting chamber, a cross mounting bracket, a motor, and fan blades. A controller and four support legs are fixedly connected to the bottom of the purification cylinder. A noise reduction component for noise reduction is provided on the outer wall of the purification cylinder. A filter element for purifying air is provided on the inner side of the purification cylinder. The noise reduction component includes a first noise reduction cylinder. A second noise reduction cylinder is fixedly connected to the top surface of the first noise reduction cylinder. Through holes are opened on the side of the second noise reduction cylinder away from the first noise reduction cylinder and on its circumferential surface.

[0008] Preferably, the surface of the purification cylinder has six sets of air inlets, and the bottom of the purification cylinder has a threaded interface.

[0009] Preferred configuration: The purification cartridge is connected to a threaded cover via a threaded interface, and the filter element is placed on the top surface of the threaded cover.

[0010] Preferably, the surface of the first noise reduction cylinder has six square grooves, and the first noise reduction cylinder is fitted onto the surface of the purification cylinder.

[0011] Preferably, the six square slots are aligned with the six sets of air intake holes.

[0012] Preferably, the second noise reduction cylinder surrounds the fan assembly.

[0013] Preferred design: Both the first and second noise reduction tubes are three-layered, with the outermost layer made of steel, the middle layer of sound insulation cotton, and the innermost layer made of rubber.

[0014] Preferably, the inner wall of the second noise reduction cylinder is coated with a rubber-based damping coating.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] I. By incorporating a first noise-reducing cylinder and a second noise-reducing cylinder, both of which have sound-insulating cotton interlayers, noise generated by airflow can be effectively absorbed. Simultaneously, the inner layer of the first noise-reducing cylinder is made of rubber, which can reduce the slight vibrations caused by the motor within the fan assembly, converting the vibrations into heat energy and achieving a vibration damping and noise reduction effect. The airflow from the fan assembly generates air vibration noise. The second noise-reducing cylinder allows the sound-insulating cotton to partially block the motor operating noise, air vibration noise, and fan blade vibration noise of the fan assembly, achieving noise reduction. This gives the present application a high noise reduction effect, solving the problem that existing air purification equipment lacks a noise reduction structure, affecting user work efficiency and mental health.

[0017] Second, in this application, the first noise reduction cylinder along with the second noise reduction cylinder can be directly removed from the purification cylinder. At this time, the restriction and obstruction of the first and second noise reduction cylinders are removed, the purification efficiency of the fan assembly will be improved, but the noise reduction effect will be lost, thus giving this application a second use effect and increasing its applicability.

[0024] This application provides a noise reduction mechanism for an air purification device, effectively solving the problem that existing air purification devices lack noise reduction structures, which affects users' work efficiency and mental health.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing air purification devices do not have noise reduction structures, which affects users' work efficiency and mental health. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a noise reduction mechanism for an air purification device, including a purification cylinder 1. A fan assembly 2 is fixedly connected to the top surface of the purification cylinder 1. The fan assembly 2 includes an installation chamber, a cross mounting bracket, a motor, and fan blades. A controller 102 and four support legs are fixedly connected to the bottom of the purification cylinder 1. A noise reduction component for noise reduction is provided on the outer wall of the purification cylinder 1. A filter element 3 for purifying air is provided on the inner side of the purification cylinder 1. The noise reduction component includes a first noise reduction cylinder 4. A second noise reduction cylinder 5 is fixedly connected to the top surface of the first noise reduction cylinder 4. Through holes 501 are opened on the side of the second noise reduction cylinder 5 away from the first noise reduction cylinder 4 and its circumferential surface.

[0028] The surface of the purification cylinder 1 is provided with six sets of air inlets 101, and the bottom of the purification cylinder 1 is provided with a threaded interface 103.

[0029] The purification cylinder 1 is threadedly connected to the threaded cover 104 via the threaded interface 103, and the filter element 3 is placed on the top surface of the threaded cover 104.

[0030] The surface of the first noise reduction cylinder 4 has six square grooves 401, and the first noise reduction cylinder 4 is sleeved on the surface of the purification cylinder 1.

[0031] The six square slots 401 are respectively aligned with the six sets of air inlets 101.

[0032] The second noise reduction cylinder 5 surrounds the fan assembly 2.

[0033] Both the first noise reduction tube 4 and the second noise reduction tube 5 are three-layer designs: the outermost layer is made of steel, the middle layer is sound insulation cotton, and the inner layer is made of rubber.

[0034] The inner wall of the second noise reduction cylinder 5 is coated with a rubber-based damping coating.

[0035] Purification cylinder 1: As the main body of the air purification device, it provides space to accommodate the filter element 3. Its surface air inlet 101 is used to introduce outside air, and the bottom threaded interface 103 is used to connect the threaded cover 104.

[0036] Fan assembly 2: The motor drives the fan blades to rotate, which in turn drives the airflow and directs the purified air to the outside through the through hole 501 of the second noise reduction cylinder 5;

[0037] Filter element 3: Placed on the top surface of the threaded cap 104, it is used to filter and adsorb particulate matter in the air to achieve air purification;

[0038] First noise reduction cylinder 4: It is sleeved on the surface of the purification cylinder 1. Its sound insulation cotton interlayer absorbs the noise of air flow, and the inner rubber layer slows down the vibration of the purification cylinder 1, playing a role in noise reduction and vibration damping. The square groove 401 is aligned with the air inlet 101 to ensure airflow.

[0039] Second noise reduction cylinder 5: surrounds the fan assembly 2, its sound insulation cotton interlayer and rubber-based damping coating block the noise generated by the operation of the fan assembly 2, and the through hole 501 is used to export the purified air.

[0040] Air inlet 101: Allows outside air to enter the inner side of the purification cylinder 1;

[0041] Threaded interface 103: used for threaded connection with threaded cover 104, facilitating disassembly and replacement of filter element 3;

[0042] Threaded cap 104: Fixedly connected to the bottom of the purification cylinder 1 to support the filter element 3;

[0043] Square groove 401: Aligned with air inlet 101 to ensure smooth airflow into purification cylinder 1;

[0044] Through hole 501: It is opened on the second noise reduction cylinder 5 to guide the purified air to the outside.

[0045] Working principle:

[0046] In the first step, this application uses the fan assembly 2 to induce airflow. Outside air enters the inner side of the purification cylinder 1 through the air inlet 101 and is eventually blown by the fan assembly 2 to the second noise reduction cylinder 5. It is then guided to the outside through various through holes 501. During this process, the air is filtered by the filter element 3, which adsorbs particulate matter in the air, thereby achieving the effect of purifying the air.

[0047] In the second step, this application incorporates a first noise-reducing cylinder 4 and a second noise-reducing cylinder 5. Since both the first noise-reducing cylinder 4 and the second noise-reducing cylinder 5 are equipped with sound-insulating cotton layers, they can effectively absorb the noise generated by airflow. At the same time, the inner layer of the first noise-reducing cylinder 4 is made of rubber, which can reduce the slight vibration of the purification cylinder 1 caused by the motor inside the fan assembly 2, converting the vibration into heat energy, thereby achieving a vibration reduction and noise reduction effect. The airflow blown out by the fan assembly 2 will generate air vibration noise. The second noise-reducing cylinder 5 allows the sound-insulating cotton to block part of the motor operating noise, air vibration noise, and fan blade vibration noise of the fan assembly 2, thus achieving noise reduction and giving this application a high noise reduction effect.

[0048] Thirdly, in this application, the first noise reduction cylinder 4 and the second noise reduction cylinder 5 can be directly removed from the purification cylinder 1. At this time, the restriction and obstruction of the first noise reduction cylinder 4 and the second noise reduction cylinder 5 are removed, the purification efficiency of the fan assembly 2 will be improved, but the noise reduction effect will be lost, so that this application has a second use effect and increases its applicability.

[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
