Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, specifically, it relates to an air purification device with an air curtain. Background Technology

[0002] Currently, commonly used commercial air purification devices include a housing, an air duct inside the housing, a centrifugal fan inside the air duct, and a filter. The air duct has an air inlet and an air outlet. Unpurified air enters the air duct through the air inlet under the action of the centrifugal fan. Impurities such as fabric fibers and dust contained in the air are removed by the filter, resulting in purified air. Finally, the purified air leaves the air duct through the air outlet. When the purification device is placed in a closed space, the purified air that has been filtered and dust-removed from the air outlet will continuously mix with the unpurified air that has not been filtered and dust-removed from the air inlet and re-enter the air duct for purification and dust removal. This causes the dust removal effect of the air purification device to decrease and requires more time to complete the dust removal process.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0038] like Figure 1 and Figure 2 As shown, this utility model provides an air purification device with an air curtain, comprising:

[0039] Casing 1;

[0040] The air duct 2 is located inside the housing 1 and has an air inlet 21 and an air outlet 22 facing the same direction.

[0041] Fan 3 is installed inside air duct 2, located between air inlet 21 and air outlet 22 of air duct;

[0042] Air curtain device 4, which is used to form an air curtain at the air outlet 22 of the air duct to prevent the exchange of unpurified air and purified air.

[0043] In this embodiment of the invention, an air curtain is formed at the air outlet 22 of the air duct. The air curtain can prevent the exchange between clean and unpurified air, and can ensure to the greatest extent that the air entering from the air inlet 21 of the air duct through the air purification device is unpurified. This allows the air purification device to maintain a high purification efficiency and complete the air dust removal and purification in a unit space in a shorter time.

[0044] Unpurified air is located at air inlet 21 of the air duct, and purified air is located at air outlet 22 of the air duct.

[0045] The housing 1 is used to house and protect the various internal components.

[0046] The air duct 2 has an air inlet 21 and an air outlet 22 facing the same direction. This means that the direction of air intake and exhaust is consistent, which helps to form a stable airflow within the air duct 2. The air duct 2 is curved within the housing 1.

[0047] The air purification device includes a filter device 7 installed in the air duct 2, and the filter device 7 is located between the air inlet 21 of the air duct and the fan 3;

[0048] The fan 3 generates airflow by rotating, which pushes the unpurified air into the air inlet 21 of the air duct and pushes the purified air obtained after being purified by the filter device 7 out of the air outlet 22 of the air duct; the fan 3 is a centrifugal fan.

[0049] When the fan 3 is working, the air curtain device 4 will use high-speed airflow to form a barrier at the air outlet 22 of the air duct. This barrier can prevent the purified air from flowing back to the area of ​​unpurified air.

[0050] For the filter device 7, the filter device 7 is a filter screen installed in the air duct 2. The filter screen is installed at the air inlet 21 of the air duct 2 or at a position of the air duct 2 away from the air inlet 21. The filter screen covers the radial section of the air duct 2.

[0051] A negative ion generator is also installed in the air duct 2 to increase the negative ion content of the air in the air duct 2. The negative ion generator is located between the filter device 7 and the fan 3.

[0052] The air duct 2 is also equipped with a UV germicidal lamp to kill bacteria in the air. The UV germicidal lamp is located between the filter device 7 and the negative ion generator.

[0053] An air quality detector is also installed inside the air duct 2. The air quality detector is connected to a UV germicidal lamp and a negative ion generator respectively. It is used to detect the air quality inside the air duct 2 and control the start of the UV germicidal lamp and / or negative ion generator according to the detection results, so as to improve the air quality flowing through the air duct 2 and thus improve the indoor air circulation.

[0054] In an embodiment of this utility model, the air curtain device 4 includes a power unit 41 that provides airflow to form an air curtain at the air outlet 22 of the air duct.

[0055] In the embodiments of this utility model, to form such an effective air curtain, a stable and powerful airflow is required as support. This brings us to the key part of the air curtain device 4 - the power unit 41. The power unit 41 is the component that provides driving force. It is responsible for providing the required airflow at the air outlet 22 of the air duct of the entire air curtain device 4. The power unit 41 draws in and accelerates the air through the fan 3 or other airflow generating device inside the air duct 2, and then sends it out through the air duct 2, finally forming a continuous and stable airflow barrier at the air outlet.

[0056] Specifically, the power unit 41 is the fan 3 located in the air duct 2, and the fan 3 has a fan 3 outlet that communicates with the air duct 2;

[0057] The air outlet of the fan 3 is positioned facing the air outlet 22 of the air duct, so that the outflow direction of the airflow provided by the fan 3 is the same as the orientation of the air outlet 22 of the air duct.

[0058] The power unit 41 is the fan 3 located in the air duct 2. The fan 3 allows unpurified air to enter the air duct 2 and purified air to flow out of the air duct 2. On the other hand, it provides airflow to form an air curtain at the air outlet 22 of the air duct, thus realizing the dual function of the fan 3.

[0059] The air outlet of the fan 3 is set to face the air outlet 22 of the air duct. This design ensures that the airflow direction generated by the fan 3 is consistent with the orientation of the air outlet 22 of the air duct. This also makes the extension direction of the air curtain consistent with the orientation of the air outlet 22 of the air duct. The air blown by the fan 3 will flow out along the direction of the air outlet 22 of the air duct. This layout helps to ensure smooth airflow and may improve the overall wind efficiency or guidance.

[0060] In an embodiment of this utility model, the housing 1 is provided with an air outlet grille 5 covering the air outlet 22 of the air duct, which is used to divide the air outlet 22 of the air duct into a number of densely distributed airflow nozzles.

[0061] In this embodiment of the invention, the air outlet 22 is cleverly divided into multiple densely distributed airflow nozzles by the setting of the air outlet grille 5. This design has several advantages: First, it can more evenly distribute the airflow generated by the fan 3 to each airflow nozzle, avoiding excessive concentration or insufficient airflow; second, the presence of the air outlet grille 5 can also filter and regulate the airflow to a certain extent, making the final outflowing airflow more stable and gentle; third, this layout can also help improve the overall ventilation efficiency and comfort, especially in situations where precise control of airflow distribution is required; finally, the air outlet 22 is designed in a dense, porous form, and with the use of a high-power centrifugal fan, the wind speed at the air outlet 22 can reach more than 15m / s, increasing the wind speed at the air outlet 22 and creating favorable conditions for forming an air curtain at the air outlet 22.

[0062] In the embodiments of this utility model, the air outlet 22 and the air inlet 21 of the air duct are located on one side of the casing 1 in the circumferential direction and are arranged along the circumferential direction of the casing 1.

[0063] The size of the air outlet 22 is smaller than the size of the air inlet 21.

[0064] In the embodiments of this utility model, the air outlet 22 and the air inlet 21 of the air duct are both located on one side of the casing 1 in the circumferential direction, and they are arranged along the circumferential direction of the casing 1. This layout helps to ensure smooth airflow, and also benefits the overall layout and aesthetics of the equipment.

[0065] With the flow rate remaining constant, the smaller size of the air outlet 22 compared to the air inlet 21 increases the airflow velocity at the air outlet 22, which helps to provide better performance in applications requiring high-speed airflow and facilitates the formation of an air curtain. Furthermore, by reducing the size of the air outlet 22, the airflow distribution can be controlled more precisely, which helps to provide better comfort and efficiency in applications requiring fine control of airflow direction and intensity. Additionally, reducing the size of the air outlet 2 can also help reduce the noise generated by the airflow, because as the airflow velocity increases, its turbulence may decrease, thereby reducing noise generation.

[0066] Furthermore, the air outlet 22 and the air inlet 21 of the air duct are both elongated strip structures extending vertically;

[0067] The air inlet 21 of the air duct extends upward beyond the top of the air outlet 22 of the air duct, and extends downward beyond the bottom of the air outlet of the air duct 2.

[0068] Both the air outlet 22 and the air inlet 21 of the air duct are designed as elongated structures extending vertically. This design is usually intended to optimize airflow and meet specific ventilation requirements, and the elongated shape of the air outlet 22 helps to form an air curtain at the air outlet 22.

[0069] Since the air inlet 21 extends further upwards and downwards than the air outlet 22, it can capture air over a wider range, thereby improving air intake efficiency. This helps ensure that the equipment has sufficient airflow to meet the needs of heat dissipation or ventilation.

[0070] The elongated air inlet 21 and air outlet 22 help to create a more uniform airflow distribution inside the equipment. When the airflow enters the air duct 2 through the elongated air inlet 21, it will disperse along the length of the air duct 2, thereby avoiding excessive concentration or insufficient airflow. This uniform airflow distribution helps to improve the overall performance and efficiency of the equipment.

[0071] Furthermore, the air outlet 22 and the air inlet 21 of the air duct are both rectangular;

[0072] The width of the air outlet 22 along the circumference of the casing 1 is smaller than the width of the air inlet 21.

[0073] Both the air outlet 22 and the air inlet 21 of the air duct are designed in a rectangular shape, and the width of the air outlet 22 along the circumference of the casing 1 is smaller than the width of the air inlet 21. This design is usually to meet specific ventilation needs and optimize airflow.

[0074] By designing the air outlet 22 of the air duct to be a narrower rectangle than the air inlet 21 of the air duct, the airflow can be guided to flow out more concentratedly. This helps to reduce the diffusion and waste of airflow, improve the utilization efficiency of airflow, and facilitate the formation of an air curtain at the air outlet 22 of the air duct.

[0075] While keeping the flow rate constant, reducing the width of the air outlet 22 of the air duct will increase the airflow velocity.

[0076] In the embodiments of this utility model, the housing 1 is a cuboid;

[0077] The casing 1 has two air ducts 2 arranged vertically inside;

[0078] The air inlet 21 and air outlet 22 of each air duct 2 are arranged side by side on the front side of the casing 1.

[0079] The fans 3 in the two air ducts 2 can work simultaneously.

[0080] In the embodiments of this utility model, the housing 1 is rectangular in shape. This design is typically used to provide a stable and compact structure, while facilitating installation and transportation.

[0081] Inside the casing 1, there are two air ducts 2 arranged vertically. This layout helps to make full use of the space inside the casing 1 and may help to improve ventilation efficiency.

[0082] The air inlet 21 and air outlet 22 of each air duct 2 are arranged side by side on the front side of the casing 1, so that the airflow can smoothly enter the air duct 2 from the front side of the casing 1 and flow out from the same front side after passing the fan 3. This layout not only simplifies the airflow path, but also helps to reduce the turbulence and energy loss of the airflow inside the casing 1.

[0083] Furthermore, the fans 3 within the two ducts 2 are designed to operate simultaneously. This means that when the equipment is started, both ducts 2 will simultaneously draw in and exhaust air, thereby improving overall ventilation efficiency. Simultaneously operating fans 3 can also provide greater airflow and stronger airflow pressure to meet the needs of specific applications.

[0084] Specifically, the upper air duct 2 has an upper air duct inlet 21a and an upper air duct outlet 22a, and the lower air duct 2 has a lower air duct inlet 21b and a lower air duct outlet 22b. The upper air duct inlet 21a and the lower air duct inlet 21b are arranged vertically on the front side of the housing 1, and the upper air duct outlet 22a and the lower air duct outlet 22b are arranged vertically on the front side of the housing 1.

[0085] An upper fan 3a is installed in the upper air duct 2, and a lower fan 3b is installed in the lower air duct 2.

[0086] The air curtain device 4 includes an upper power unit 41a that provides airflow to form an air curtain at the upper air outlet 22a and a lower power unit 41b that provides airflow to form an air curtain at the lower air outlet 22b. The upper power unit 41a is the aforementioned upper fan 3a and the lower power unit is the aforementioned lower fan 3b.

[0087] An upper air intake grille 6a is provided at the upper air intake 21a, and a lower air intake grille 6b is provided at the lower air intake 21b.

[0088] An upper air outlet grille 5a is provided at the upper air outlet 22a, and a lower air outlet grille 5b is provided at the lower air outlet 22b.

[0089] In this embodiment of the present invention, the housing 1 is provided with an air inlet grille 6 that covers the air inlet 21 of the air duct.

[0090] In this embodiment of the utility model, the functions of the air inlet grille are as follows: 1. Protecting the air inlet 21 of the air duct, i.e., preventing external impurities such as dust and debris from directly entering the air duct 2, thereby protecting the fan 3 and other components inside the air duct 2 from damage. This is crucial for maintaining the long-term stable operation of the equipment. 2. Optimizing airflow, i.e., the air inlet grille 6, through its unique structure and arrangement, can further optimize the airflow entering the air duct 2. It can ensure that the airflow is more evenly distributed at the air inlet 21, avoiding excessive concentration or absence of local airflow, thereby improving overall ventilation efficiency. 3. Reducing noise, i.e., the air inlet grille 6 can also reduce noise. When external airflow enters the air duct 2 through the grille, the obstruction effect of the grille can make the airflow more stable, thereby reducing the noise generated by the airflow. 4. Enhancing aesthetics, i.e., the air inlet grille 6 can also serve as part of the housing 1, enhancing the aesthetics of the equipment.
