[0035] The realization of the object, functional features and advantages of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then such directional indications will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] In related technologies, in order to increase the air volume, at least two fans are usually arranged inside an air purification device. Generally, there are two types of fans used in traditional air purification devices, namely fully enclosed fans and open fans. For a fully enclosed fan, a wind collecting cylinder is arranged on the outer periphery of the fan. This fully enclosed fan can collect the air flow driven by the fan through the wind collecting cylinder to increase the wind pressure and enhance the driving force of the fully enclosed fan to blow air forward. Therefore, the air flows blown out by two adjacent fully enclosed fans are not easily diffused, and it is not easy to have a situation where two air flows collide and interfere with each other. Thus, there is no need to set a partition between the air outlet sides of two adjacent fully enclosed fans. However, for an open fan, there is no wind collecting cylinder arranged on the outer periphery of the fan. The air flow driven by this open fan advances along its axial direction and spirally diffuses along its radial direction. Therefore, when the air flows blown out by two adjacent open fans diffuse along the radial direction, they are prone to collide and interfere with each other, resulting in partial air volume loss, and further leading to a reduction in the air output volume of the air purification device.

[0040] In view of this, the present invention provides an embodiment of an air purification device. The air purification device can be applied to purify pollutants in the air to provide clean air for users, such as purifying any one or more of pollutants such as viruses, bacteria, dust, or particulate matter in the air. The air purification device of the present invention can blow out the purified air from its circumferential direction, and can also avoid the interference between the two air flows blown out by the two fans, so as to reduce the air volume loss and increase the air output volume of the air purification device.

[0041] Please refer to Figures 1 to 3 , in an embodiment of the air purification device of the present invention, the air purification device includes a housing 100, at least two fans 400, a wind deflector 200, and an air outlet partition 300. Among them, the housing 100 is provided with an air outlet 120, and the air outlet 120 includes at least two air outlet areas; the at least two fans 400 are arranged inside the housing 100 and respectively correspond to the at least two air outlet areas one by one; the wind deflector 200 is arranged on the front side of the air outlet 120, and a wind dispersion gap 130 is formed between the edge of the wind deflector 200 and the edge of the air outlet 120; the air outlet partition 300 is arranged between the wind deflector 200 and the air outlet 120 to separate two adjacent air outlet areas.

[0042] Specifically, a cavity is arranged inside the housing 100, and the cavity can be used for installing internal components (such as fans 400, purification modules 500, etc.) of the air purification device. An air inlet 110 is arranged on the back surface of the housing 100; an air outlet 120 is arranged on the front side surface of the housing 100, and the air outlet 120 is communicated with the air inlet 110. The at least two fans 400 are all installed inside the housing 100 and are arranged opposite to the air outlet 120. The fan 400 can be an axial flow impeller or a mixed flow impeller.

[0043] AsFigure 2 , Figure 4 and Figure 5 As shown in Figure 2 , Figure 4 and Figure 5 , the number of the blowers 400 can be two or more. Taking two blowers 400 as an example, the two blowers 400 are arranged in the up-down direction, and the two blowers 400 are respectively defined as a first blower 410 and a second blower 420; correspondingly, the air outlet 120 is provided with two air outlet areas, and the two air outlet areas are respectively a first air outlet area 121 and a second air outlet area 122. The first air outlet area 121 is opposite to the first blower 410, and the second air outlet area 122 is opposite to the second blower 420.

[0044] The wind deflector 200 is installed on the housing 100 and is located on the front side of the air outlet 120; the wind deflector 200 is spaced from the air outlet 120, so as to form a wind-dispersing gap 130 between the circumference of the wind deflector 200 and the periphery of the air outlet 120. Optionally, the wind deflector 200 is plate-shaped, the wind deflector 200 has four edges, and a wind-dispersing gap 130 is formed by spacing between at least two edges of the wind deflector 200 and the edges of the air outlet 120 opposite thereto, so that the air purification device can disperse wind at least in two different lateral directions. For example, wind-dispersing gaps are formed between two edges (the upper edge and the lower edge) of the wind deflector 200 extending along its width direction and the edges of the air outlet 120; or, wind-dispersing gaps are formed between two edges (the left edge and the right edge) of the wind deflector 200 extending along its length direction and the edges of the air outlet 120. Specifically herein, wind-dispersing gaps 130 are formed between the four sides of the wind deflector 200 and the edges of the air outlet 120, so that the wind-dispersing gap 130 surrounds the circumference of the air outlet 120 for a whole circle, and further the air purification device can supply air from the circumferential side of the air outlet 120.

[0045] When the air purification device works, the blower 400 drives air to enter the interior of the housing 100 from the air inlet 110 for purification treatment, and the purified air is blown forward from the air outlet 120. When it encounters the wind deflector 200, it is intercepted by the wind deflector 200 and cannot continue to blow straight forward, so it laterally diffuses out from the wind-dispersing gap 130 between the circumference of the wind deflector 200 and the periphery of the air outlet 120, avoiding the air flow from blowing straight forward. During this process, the air flow driven by the first blower 410 is blown out from the first air outlet area 121 of the air outlet 120; the air flow driven by the second blower 420 is blown out from the second air outlet area 122 of the air outlet 120. When the two air flows blown out by the two blowers 400 flow forward to the wind deflector 200, the air flow is blocked by the wind deflector 200 and diffuses radially from the position of the wind deflector 200 opposite to the blower 400 to the periphery of the wind deflector 200, and finally diffuses to reach the wind-dispersing gap 130 and is blown out from the wind-dispersing gap 130.

[0046] It should be noted here that if there is no air outlet partition 300 provided between the wind deflector 200 and the air outlet 120, then when the two airflows blown out by the two fans 400 hit the wind deflector 200, the two airflows will spread radially in all directions after being blocked by the wind deflector 200, so that the two diffused airflows will accelerate and collide with each other (as shown in Figure 10-A and Figure 11-A , where 10 indicates the interference area where the two airflows collide with each other), resulting in a great loss of air volume. Moreover, if one or both of the two fans 400 adopt open fans (that is, there is no air collecting cylinder provided on the outer periphery of the fan 400), the airflow driven by the fan 400 advances along its axis and spreads spirally along its radial direction, so that the two airflows diffused from the adjacent two fans 400 are likely to intersect and interfere with each other, resulting in a loss of air volume; and then when hitting the wind deflector 200, an accelerated collision will occur again, which will further aggravate the degree of interference between the two airflows colliding with each other.

[0047] In the embodiment of the present invention, in order to reduce the occurrence of the above situation, an air outlet partition 300 is provided between the wind deflector 200 and the air outlet 120. The air outlet partition 300 separates the two air outlet areas of the air outlet 120 (as shown in Figure 10-B and Figure 11-B ), so that the airflow driven by the first fan 410 will be blown out from the first air outlet area 121 of the air outlet 120 to the upper side of the air outlet partition 300; while the airflow driven by the second fan 420 is blown out from the second air outlet area 122 of the air outlet 120 to the lower side of the air outlet partition 300, that is, the two airflows blown out by the two fans 400 are separated, and the two airflows are not likely to intersect and interfere with each other during the forward blowing process. Then, the two airflows blown out by the two fans 400 continue to move forward and hit the wind deflector 200. Although the two airflows will spread radially in all directions after being blocked by the wind deflector 200, the two diffused airflows will also be separated by the air outlet partition 300. Therefore, the two diffused airflows will not accelerate and collide with each other, effectively reducing the occurrence of the situation where the two airflows collide and interfere with each other, greatly reducing the air volume loss caused by the collision of the two airflows, and ensuring that the air purification device obtains a larger air output.

[0048] As for the shape and structure of the air outlet partition 300, there is no specific limitation here. For example, the air outlet partition 300 can be arranged in a flat plate shape, and the plate surface of the air outlet partition 300 is perpendicular to the plate surface of the wind deflector 200. The air outlet partition 300 can be installed on the housing 100 so that the air outlet partition 300 is fixed to the housing 100; of course, the air outlet partition 300 can also be installed on the inner half surface of the wind deflector 200 to be fixed to the wind deflector 200.

[0049] In the technical solution of the present invention, by installing the wind deflector 200 on the housing 100, the wind deflector 200 is disposed opposite to the air outlet 120, so as to form a wind-dispersing gap 130 between the circumference of the wind deflector 200 and the periphery of the air outlet 120; and an air outlet partition 300 is arranged between the wind deflector 200 and the air outlet 120, so as to use the air outlet partition 300 to separate two adjacent air outlet areas of the air outlet 120, thereby preventing interference between two airflows blown out by at least the fan 400 in the housing 100 ( Figure 10-A and Figure 11-A where 10 in means the area where two airflows interfere), and further preventing the two airflows from colliding with each other and resulting in air volume loss, ensuring that the air purification device obtains a larger air output volume.

[0050] Please refer to Figure 2 、 Figure 4 and Figure 6 , in an embodiment, the air outlet partition 300 has opposite first side 310 and second side 320; wherein, the first side 310 is fixedly connected to the inner plate surface of the wind deflector 200; the second side 320 extends into the air outlet 120.

[0051] Specifically, the inner plate surface of the wind deflector 200 is the plate surface facing the air outlet 120. The air outlet partition 300 is horizontally disposed between the inner plate surface of the wind deflector 200 and the air outlet 120. The first side 310 of the air outlet partition 300 is fixedly connected to the inner plate surface of the wind deflector 200; and the second side 320 of the air outlet partition 300 extends into the air outlet 120, so that the second side 320 of the air outlet partition 300 extends deeper into the space between two adjacent fans 400, thereby separating the two airflows before the two airflows blown out by the two fans 400 spread.

[0052] It can be understood that since the first side 310 of the air outlet partition 300 is fixedly connected to the wind deflector 200, the air outlet partition 300 can basically remain stable. Therefore, the second side 320 of the air outlet partition 300 can be suspended or fixedly connected to other structures, as long as the air outlet partition 300 can maintain balance. Of course, in order to improve the stability of the air outlet partition 300, the second side 320 of the air outlet partition 300 can also be connected to the internal components of the housing 100, or the air outlet grille 140 or bracket provided at the air outlet 120, so that the air outlet partition 300 is more stably installed and is not easily shaken by the blowing of the airflow.

[0053] Please continue to refer to Figure 2 、 Figure 4 and Figure 6, in one embodiment, the air outlet partition 300 further has a wind guiding side 330 connecting the second side 320 and the first side 310. The wind guiding side 330 extends obliquely outward from the second side 320 to the first side 310. That is to say, the wind guiding side 330 extends obliquely from the inside to the outside towards the air dispersion gap 130. Therefore, when the fan 400 operates, the fan 400 rotates and advances the airflow along the axial direction and rotates forward. During this process, these airflows gradually rotate and diffuse radially to the fan 400. The airflows diffused onto the surface of the air outlet partition 300 will flow towards the air dispersion gap along the inclined direction of the wind guiding side 330 of the air outlet partition 300, greatly reducing the airflow resistance and reducing the air volume loss.

[0054] Furthermore, the distance between the two wind guiding sides 330 of the air outlet partition 300 is gradually increased from its second side 320 to its first side 310, so that the wind guiding side 330 is inclined. The distance between the two wind guiding sides 330 of the air outlet partition 300 is the length of the air outlet partition 300. As Figure 7 shown, L represents the length of the air outlet partition 300; L1 represents the length of the first side 310 of the air outlet partition 300; L2 represents the length of the second side 320 of the air outlet partition 300.

[0055] Specifically, the length of the first side 310 is greater than the length of the second side 320 (i.e., L1 > L2). Therefore, the length of the air outlet partition 300 gradually increases from the second side 320 to the first side 310. With such a setting, both wind guiding sides 330 of the air outlet partition 300 can extend obliquely from the inside to the outside towards the air dispersion gap 130. When the airflow blown out by the fan 400 flows onto the surface of the air outlet partition 300, the airflow will be divided and blown out towards the air dispersion gaps on both sides along the wind guiding sides 330 at both ends of the air outlet partition 300, thereby guiding the airflow to the air dispersion gap 130, reducing the resistance of the airflow, further reducing the air volume loss, ensuring that more airflows are blown out from the air dispersion gap 130, and increasing the air volume output of the air purification device.

[0056] Regarding the shape structure of the wind guiding side 330 of the air outlet partition 300, the wind guiding side 330 can be set as a straight edge extending obliquely; or, the wind guiding side 330 can also be set as an arc edge. It only needs the wind guiding side 330 to be relatively smooth and the resistance of the wind guiding side 330 to the airflow to be small. Specifically, in this embodiment, the wind guiding side 330 of the air outlet partition 300 is arc-shaped from the second side 320 to the first side 310. That is to say, the wind guiding side 330 is set as an arc edge. In this way, the wind guiding side 330 can be made more rounded, better adapted to the movement trajectory of the airflow diffused by the fan 400, and thus can more effectively guide the airflow, greatly reducing the resistance of the airflow.

[0057] Please refer to Figure 2 and Figure 9 Here, it is considered that the fan 400 includes a hub 401 and a plurality of blades 402 arranged at circumferential intervals along the hub 401. The blades 402 are inclined and mounted on the hub 401, so that the blades 402 have a certain installation angle. Therefore, the airflow blown out by the fan 400 has a diffusion angle that diffuses radially and forward. If the inclination angle θ of the air guiding side edge 330 is close to the angle of the diffused airflow of the fan 400, the resistance of the air outlet partition 300 to guide the airflow can be greatly reduced. The inclination direction of the air guiding side edge 330 is related to the width of the air outlet partition 300 (i.e., the distance between the first side edge 310 and the second side edge 320); the larger the width of the air outlet partition 300, the smaller the inclination angle of the air guiding side edge 330 ( Figure 6 In [reference], θ is represented as the inclination angle of the air guiding side edge 330); conversely, the smaller the width of the air outlet partition 300, the larger the inclination angle of the air guiding side edge 330.

[0058] Please refer to Figure 2 、 Figure 7 and Figure 9 In view of the above situation, the width of the air outlet partition 300 and the installation angle of the fan 400 are studied. The ratio of the distance between the first side edge 310 and the second side edge 320 of the air outlet partition 300 (i.e., the width of the air outlet partition 300) to the length of the second side edge 320 is expressed by the formula as W / L2, where W represents the width of the air outlet partition 300 and L2 represents the length of the second side edge 320. Through research and analysis, it is obtained that when the ratio of the distance between the first side edge 310 and the second side edge 320 of the air outlet partition 300 to the length of the second side edge 320 is greater than or equal to (tanα) / 2 (that is: W / L2≥(tanα) / 2), where tanα = 2H / D3, α is the installation angle of the blades of the fan 400 (not shown in the figure), H is the distance between the centers of two adjacent fans 400, and D3 is the diameter of the fan 400, the inclination angle of the air guiding side edge 330 can be greater than or equal to the angle of the diffused airflow of the fan 400, which helps the air guiding side edge 330 to guide the airflow diffused from the fan 400 to the lateral direction to the air dispersion gap 130. In this way, not only the function of the air outlet partition 300 to separate the airflow is strengthened, but also the direction of the airflow diffusion does not change greatly, so that the resistance of the air outlet partition 300 to guide the airflow can be greatly reduced, and the air volume loss can be effectively reduced.

[0059] Also considering that the rotational diameter of the airflow initially blown out by the fan 400 is comparable to the diameter of the fan 400. If the length of the second side 320 of the air outlet partition 300 is too small, and the difference between the length of the second side 320 and the diameter of the fan 400 is large, then the second side 320 of the air outlet partition 300 may only be able to separate the inner-layer airflow closer to the fan, and it is difficult to separate the outer-layer airflow of the fan. However, the length of the second side 320 of the air outlet partition 300 cannot be infinitely large either, because the second side 320 extends into the air outlet 120, and the width dimension of the air outlet 120 is usually not much different from the diameter of the fan 400. Therefore, in order to ensure that the second side 320 can extend into the air outlet 120, the length of the second side 320 cannot be designed too large.

[0060] In view of the above situation, optionally, the difference between the length of the second side 320 of the air outlet partition 300 and the diameter of the fan 400 is less than or equal to 20 mm. Figure 7 In the figure, L2 is the length of the second side 320; Figure 9 In the figure, D3 is the diameter of the fan 400. Therefore, the difference between the length of the second side 320 of the air outlet partition 300 and the diameter of the fan 400 is less than or equal to 20 mm. Expressed by a formula, it should be |L2 - D3| ≤ 20 mm. That is to say, D3 - 20 mm ≤ L2 ≤ D3 + 20 mm. This can make the length of the second side 320 of the air outlet partition 300 have a small difference from the diameter of the fan 400, that is, it can ensure that the second side 320 of the air outlet partition 300 can extend into the air outlet 120, and it can ensure that the air outlet partition 300 can separate the inner and outer layer airflows of one fan 400 from the inner and outer layer airflows of another fan 400. In practical applications, the length of the second side 320 can be reasonably designed according to the diameter of the fan 400.

[0061] Please continue to refer to Figure 2 、 Figure 7 and Figure 9 In an embodiment, to enhance the effect of the air outlet partition 300 in separating the airflow, the distance between the first side 310 and the second side 320 of the air outlet partition 300 should be greater than or equal to the difference between the distance between the centers of two adjacent fans 400 and the diameter of the fan 400. Specifically, Figure 2 D1 in the figure represents the distance between the centers of two adjacent fans 400; Figure 7 W in the figure represents the distance between the first side 310 and the second side 320; Figure 9D3 in it represents the diameter of the fan 400. Therefore, W≥D1 - D3. The distance between the first side 310 and the second side 320 of the air outlet partition 300 is actually the width of the air outlet partition 300; the difference between the distance between the centers of two adjacent fans 400 and the diameter of the fan 400 is actually the height of the gap between two adjacent fans 400. W≥D1 - D3 means that the width of the air outlet partition 300 is greater than the height of the gap between two adjacent fans 400.

[0062] Please refer to Figure 6 and Figure 7 , Figure 7 in which L1 represents the length of the first side 310 of the air outlet partition 300. For the length of the first side 310 of the air outlet partition 300, since the length of the air outlet partition 300 is gradually increasing from the second side 320 to the first side 310, it should be that the length of the first side 310 is greater than the length of the second side 320, that is, L1>L2. Theoretically speaking, the larger the length of the first side 310, the better the air flow separation effect of the air outlet partition 300 on two fans 400; however, correspondingly, a wind shield 200 with a larger width size is required, otherwise the air outlet partition 300 will be exposed from the inner plate surface of the wind shield 200 to both sides. Obviously, this will lead to an increase in the width size of the air purification device, resulting in an increase in the overall body volume.

[0063] Therefore, the first side 310 of the air outlet partition 300 should be less than or equal to the width of the wind shield 200. As Figure 1 shown, D0 represents the width of the wind shield 200. Therefore, there is L2<L1≤D0. In this way, the entire air outlet partition 300 can be hidden inside the inner plate surface of the wind shield 200, that is, without increasing the width of the wind shield 200 and without being exposed from the inner plate surface of the wind shield 200.

[0064] Please continue to refer to Figure 6 and Figure 8 , in an embodiment, the thickness of the air outlet partition 300 is gradually decreasing from the middle of the air outlet partition 300 to any one of its air guiding sides 330. Specifically speaking, connecting the midpoints of the first side 310 and the second side 320 of the air outlet partition 300 to obtain a connecting line, and the part of the air outlet partition 300 around the connecting line is the middle of the air outlet partition 300. The larger thickness in the middle of the air outlet partition 300 can make the air outlet partition 300 have greater strength and not be easily deformed; the smaller thickness at the end of the air outlet partition 300 close to the air guiding side 330 can make the end thinner, and this end occupies less space in the air dispersion gap 130, making the opening area of the air dispersion gap 130 larger, so as to increase the air output.

[0065] It can be understood that the thickness of the middle part of the air outlet partition plate 300 is the largest; while the thickness of the end part of the air outlet partition plate 300 located at the air guiding side edge 330 is the smallest. Figure 8 In, H max represents the maximum thickness of the air outlet partition plate 300; H min represents the minimum thickness of the air outlet partition plate 300. Optionally, the maximum thickness of the air outlet partition plate 300 is greater than or equal to 3 mm and less than or equal to 10 mm, that is, 3 mm ≤ H max ≤ 10 mm. The value of H max can be but is not limited to: 3 mm, 5 mm, 7 mm, 9 mm, 10 mm, etc. The minimum thickness of the air outlet partition plate 300 is greater than or equal to 1 mm and less than or equal to 6 mm, that is, 1 mm ≤ H min ≤ 6 mm. The value of H min can be but is not limited to: 1 mm, 2 mm, 4 mm, 5 mm, 6 mm, etc.

[0066] Please refer to Figure 2 , Figure 7 and Figure 9 , based on any one of the above embodiments, the wind deflector 200 is movably mounted on the housing 100, and the wind deflector 200 can be moved relative to the housing 100 to open and close the air dispersion gap 130. Specifically, the wind deflector 200 has an initial position for closing the air dispersion gap 130 and an open position for opening the air dispersion gap 130, and the wind deflector 200 can be moved relative to the housing 100 to switch between the initial position and the open position.

[0067] When the air purification device is idle, the wind deflector 200 is in the initial position. At this time, the wind deflector 200 covers the air outlet 120, and the wind deflector 200 is in contact with the housing 100 in the circumferential direction to close the air dispersion gap 130. It is worth mentioning that the air purification device does not have a front panel on the front side of the housing 100; when the wind deflector 200 is in the initial position, the wind deflector 200 covers the front side of the housing 100, and the wind deflector 200 also serves as the front panel of the housing 100. When using the air purification device, the wind deflector 200 is moved to the open position. At this time, there is a distance between the wind deflector 200 and the air outlet 120, so that an air dispersion gap 130 is formed between the circumferential direction of the wind deflector 200 and the air outlet 120.

[0068] As for the installation method in which the wind deflector 200 is movably installed on the housing 100, there can be various design methods. For example, in one embodiment, the wind deflector 200 is rotatably installed on the housing 100, so that the wind deflector 200 can rotate relative to the housing 100 to switch positions. In another embodiment, the wind deflector 200 is movably installed on the housing 100 in the front-rear direction, so that the wind deflector 200 can move relative to the housing 100 to switch positions.

[0069] To prevent the air outlet partition 300 from interfering with the movement of the wind deflector 200, the air outlet partition 300 can be fixedly connected to the wind deflector 200, so that the air outlet partition 300 and the wind deflector 200 are arranged to move together. That is to say, when the wind deflector 200 moves, it can drive the air outlet partition 300 to move in the same direction. For example, when the wind deflector 200 is in the initial position, the wind deflector 200 covers the air outlet 120, and the air outlet partition 300 is received inside the air outlet 120; when the wind deflector 200 moves outward to the open position, the wind deflector 200 pulls the air outlet partition 300 outward, so that the air outlet partition 300 is located between the wind deflector 200 and the air outlet 120. With such an arrangement, the air outlet partition 300 can be prevented from interfering with the movement of the wind deflector 200.

[0070] As for the way of fixing the air outlet partition 300 and the wind deflector 200, the air outlet partition 300 can be integrally formed with the wind deflector 200. Of course, in other embodiments, the air outlet partition 300 can also be separately manufactured and then installed on the wind deflector 200. Specifically, it can be reasonably designed according to the actual production difficulty, and no specific limitation is set here.

[0071] Based on any of the above embodiments, the housing is further provided with an air inlet communicating with the air outlet 120, and the air inlet includes at least two air inlet areas, and the at least two air inlet areas respectively correspond to the at least two blowers 400 one by one. Specifically, here, the air inlet includes two air inlet areas, which are the first air inlet area 111 and the second air inlet area 112 respectively. The air inlet side of the first blower 410 is disposed opposite to the first air inlet area 111, and the air inlet side of the second blower 420 and the second air inlet area 112.

[0072] Further, the air purification device further includes an air inlet partition 600, and the air inlet partition 600 is disposed inside the air inlet to separate two adjacent air inlet areas. The air inlet partition 600 can separate the air inlet airflows of the two blowers 400 to prevent the air inlet airflows of the two blowers 400 from interfering with each other (commonly known as "grabbing air").

[0073] Optionally, the air purification device further includes a plurality of purification modules 500 installed in the housing 100, and the plurality of purification modules 500 are arranged between the air inlet side of the fan 400 and the air inlet 110. Specifically, among the plurality of purification modules 500, there are a plurality of first purification modules 510 and a plurality of second purification modules 520; wherein, the plurality of first purification modules 510 are arranged between the first fan 410 and the first air inlet area 111 of the air inlet 110, and the plurality of first purification modules 510 are arranged in sequence along the air inlet direction; the plurality of second purification modules 520 are arranged between the second fan 420 and the second air inlet area 112 of the air inlet 110, and the plurality of second purification modules 520 are arranged in sequence along the air inlet direction. The plurality of purification modules 500 can be configured as purification modules 500 for purifying different pollutants, or can be configured as purification modules 500 for purifying the same pollutant.

[0074] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
