Description

Technical Field

[0001] This utility model relates to the field of negative ion generator technology, and in particular to a heat dissipation and noise reduction structure for a negative ion generator. Background Technology

[0002] As people pay increasing attention to the quality of their living environment, air purification equipment is becoming increasingly popular. The waterfall-style negative ion generator, as a new type of air purification device, simulates the process of negative ion generation from a natural waterfall. It generates a large number of negative ions through the collision of water and high-pressure gas, which can effectively improve indoor air quality.

[0003] The core components of a waterfall-style negative ion generator include a high-pressure gas generation system and a negative ion generator. The compressor in the high-pressure gas generation system plays a crucial role, providing the necessary high-pressure gas for the water-gas reaction. However, the noise generated by the compressor during operation is particularly noticeable in quiet indoor environments, potentially interfering with sleep, reading, or work, severely impacting the user experience. Simultaneously, the operation of the internal motor and the gas compression process generate a significant amount of heat; excessively high temperatures can affect the compressor's performance and lifespan, reducing the stability and reliability of the equipment. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a heat dissipation and noise reduction structure for a negative ion generator, which can effectively reduce the noise and heat generated by the compressor and improve the user experience.

[0005] Therefore, the technical solution of this utility model is: a heat dissipation and noise reduction structure for a negative ion generator, including a base, a housing, a compressor, and a fan; the compressor is mounted on the base via a shock-absorbing column, and a partition is provided between the base and the compressor, with an opening on the partition for the shock-absorbing column to pass through; a shielding cover is fitted around the compressor, and the bottom of the shielding cover is fixed to the partition; the fan is fixed to the top of the shielding cover, and a vent is provided on the top of the shielding cover, opposite to the air outlet of the fan; the partition has a mesh structure located directly below the compressor;

[0006] The base is divided into a first silencing chamber, a second silencing chamber, a third silencing chamber, and a fourth silencing chamber by an H-shaped partition. The first silencing chamber is located below the mesh structure of the partition. The first silencing chamber is connected to the second silencing chamber. The second silencing chamber is connected to the third and fourth silencing chambers on both sides. The third and fourth silencing chambers are connected to the exhaust port on the base.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the inner wall of the shielding cover is lined with sound-absorbing cotton, and a sound-absorbing chamber is formed inside the shielding cover.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom surfaces of the first silencing cavity, the second silencing cavity, the third silencing cavity and the fourth silencing cavity are all provided with sound insulation cotton.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the H-shaped partition includes two vertical plates on both sides and a horizontal plate in the middle. The vertical plates divide the base into three parts: left, middle and right. The left and right parts are the third silencing chamber and the fourth silencing chamber, respectively. The middle part is divided into the first silencing chamber and the second silencing chamber by the horizontal plate. The horizontal plate is provided with a first vent that connects the first silencing chamber and the second silencing chamber. The vertical plates on both sides of the second silencing chamber are provided with second vents for connecting the third silencing chamber and the fourth silencing chamber.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the exhaust ports on both sides of the base are grille structures.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the housing includes a front housing and a rear housing, which are fixed together as one unit. The rear housing is provided with an air inlet, and an air vent plate is provided at the air inlet.

[0012] When in operation, the fan is turned on, and air enters from the air inlet of the rear housing and is blown downwards into the soundproof chamber of the shield. The sound-absorbing cotton on the inner wall of the soundproof chamber can play a role in noise reduction.

[0013] The anechoic chamber has a grid structure with multiple uniform mesh openings below it, which can optimize airflow distribution and reduce turbulence, reduce airflow noise, improve structural strength and rigidity, and control wind pressure and flow rate (through the opening ratio).

[0014] The wind flows into the first sound-absorbing cavity of the base through the mesh structure and impacts the sound-absorbing cotton at the bottom. The first sound-absorbing cavity can play a role in noise reduction, and the sound-absorbing cotton can play a role in sound absorption and heat insulation.

[0015] The air in the first silencing chamber passes through the first vent and abruptly enters the second silencing chamber. This process causes a sudden change in the volume of the chamber, which can play a role in silencing (principle: using the sudden change in acoustic impedance to cause reflection, combined with resonance absorption and interference cancellation to achieve energy attenuation).

[0016] After the air enters the second silencing chamber, it flows to the second vents on both sides and into the third and fourth silencing chambers. The silencing core from the large chamber to the small chamber is sound wave reflection and vortex energy dissipation, which is effective for mid-to-high frequency noise (such as fan hissing and airflow whistling).

[0017] After the air enters the third and fourth silencing chambers, it is discharged from the grille-shaped exhaust ports on both sides of the base. The grille design can improve heat dissipation efficiency, enhance protection and durability, reduce noise, and combine aesthetics and functionality.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] A soundproof cover with sound-absorbing cotton is installed on the outside of the compressor to form a soundproof chamber, which can absorb the noise generated by the compressor during operation, reduce the transmission of noise at the source, and effectively reduce the impact of noise on the surrounding environment. A mesh partition is set between the cover and the base to optimize airflow distribution and reduce turbulence. Multiple sound-absorbing cavities are set in the base, which can effectively attenuate noise of different frequencies by using the principles of acoustic impedance change, resonance absorption, interference cancellation, and sound wave reflection and vortex energy dissipation. The exhaust port adopts a grille structure, which can buffer and reduce the noise of the exhaust airflow, preventing the airflow from being directly discharged and generating large noise, thus integrating aesthetics and noise reduction function into one.

[0020] The compressor is cooled directly by a fan. After passing through the compressor, the air carries away the heat it generates and passes through the sound-absorbing cavity structure in the base. Finally, the air is discharged from the grille-shaped exhaust ports on both sides, forming an effective heat dissipation channel. This ensures that the compressor operates within a suitable temperature range, improves its performance and service life, and enhances the stability and reliability of the equipment.

[0030] See the attached figures. The heat dissipation and noise reduction structure of the negative ion generator described in this embodiment includes a base 1, a housing, a compressor 2, and a fan 3; the housing includes a front housing 41 and a rear housing 42, which are fixed together and installed on the base 1; the rear housing 42 is provided with an air inlet 43, and an air vent plate 44 is provided at the air inlet 43.

[0031] The compressor 2 is mounted on the base 1 via shock-absorbing columns 5, which can be commercially available rubber shock-absorbing columns. A partition 6 is provided between the base 1 and the compressor 2. The partition 6 has openings for the shock-absorbing columns 5 to pass through, ensuring no contact between the compressor 2 and the partition 6, and forming a sound-absorbing zone between the partition 6 and the base 1. The partition 6 has a mesh structure 61 located directly below the compressor 2. A shielding cover 7 is fitted onto the outside of the compressor 2. The bottom of the shielding cover 7 is fixed to the partition 6. The inner wall of the shielding cover 7 is lined with sound-absorbing cotton, creating a sound-absorbing chamber inside. Simultaneously, the shielding cover 7 completely covers the mesh structure 61 of the partition 6, connecting the shielding cover 7 with the sound-absorbing zone inside the base 1. A fan 3 is fixed to the top of the shielding cover 7. The top of the shielding cover 7 has a vent 71, opposite to the air outlet of the fan 3. The fan 3 can blow air directly onto the compressor 2 from top to bottom, providing effective cooling.

[0032] The sound-absorbing area inside the base 1 is provided with an H-shaped partition 8. The H-shaped partition 8 includes two vertical plates 81 on both sides and a horizontal plate 82 in the middle. The vertical plates 81 divide the sound-absorbing area of ​​the base 1 into three parts: left, middle and right. The left and right parts are the third sound-absorbing cavity 93 and the fourth sound-absorbing cavity 94, respectively. The middle part is divided into a first sound-absorbing cavity 91 and a second sound-absorbing cavity 92 by the horizontal plate 82. The first sound-absorbing cavity 91 is located below the mesh structure 61 of the partition 6 and is connected to the sound-absorbing chamber inside the shield 6. The horizontal plate 82 is provided with a first vent 95 that connects the first sound-absorbing cavity 91 and the second sound-absorbing cavity 92. The vertical plates 81 on both sides of the second sound-absorbing cavity 92 are provided with second vents 96 for connecting the third sound-absorbing cavity 93 and the fourth sound-absorbing cavity 94. The bottom surfaces of the first sound-absorbing cavity 91, the second sound-absorbing cavity 92, the third sound-absorbing cavity 93 and the fourth sound-absorbing cavity 94 are all provided with sound-absorbing cotton. The base 1 has exhaust ports 11 with a grid structure on both sides, and the third silencing chamber 93 and the fourth silencing chamber 94 are connected to the exhaust ports 11 on both sides of the base 1.

[0033] When the negative ion generator is working, the compressor needs to be started. The compressor can generate high-pressure gas, which is then introduced into the negative ion cup (not shown in the figure) to collide with the liquid, causing the liquid to generate negative ions upon impact.

[0034] When the compressor is working, the fan 3 is turned on, and air enters from the air inlet 43 of the rear housing 42 and is blown downward into the shield 7 by the fan 3, directly blowing on the compressor 2 and carrying away the heat generated by the compressor. The sound-absorbing cotton on the inner wall of the shield 7 can play a role in noise reduction.

[0035] Below the shielding cover 7 is the mesh structure 61 of the partition 6, which adopts a multi-mesh uniform design to optimize airflow distribution and reduce turbulence, reduce airflow noise, improve structural strength and rigidity, and control wind pressure and flow rate (through the opening ratio). The air flows into the first sound-absorbing cavity 91 of the base 1 through the mesh structure 61, impacting the sound-absorbing cotton at the bottom. The first sound-absorbing cavity 91 can play a role in noise reduction, and the sound-absorbing cotton can play a role in sound absorption and heat insulation.

[0036] The air in the first silencing chamber 91 passes through the first vent 95 and abruptly enters the second silencing chamber 92. This abrupt change in the volume of the chambers can achieve a silencing effect (principle: using the abrupt change in acoustic impedance to cause reflection, combined with resonance absorption and interference cancellation to achieve energy attenuation). After entering the second silencing chamber 92, the air flows to the second vents 96 on both sides and flows into the third silencing chamber 93 and the fourth silencing chamber 94. The core of the silencing effect from the large chamber to the small chamber is sound wave reflection and vortex energy dissipation, which is effective for mid-to-high frequency noise (such as fan hissing and airflow whistling). After entering the third silencing chamber 93 and the fourth silencing chamber 94, the air is discharged from the grille-shaped exhaust ports 11 on both sides of the base 1. The grille design can improve heat dissipation efficiency, enhance protection and durability, reduce noise, and integrate aesthetics and functionality.
