[0043] This application provides an air purifier, which includes a housing 100, a filter assembly 200, an air distribution assembly 300, an airflow drive assembly 400, and a germicidal lamp 500.

[0044] In some specific embodiments, the housing 100 has an installation chamber, the housing 100 has a polygonal cross-section with rounded corners, the housing 100 has an airflow channel, the filter assembly 200 is disposed at the bottom of the installation chamber, the shape of the filter assembly 200 is adapted to the housing 100, the filter assembly 200 has a polygonal cross-section with rounded corners, the air distribution assembly 300 is located at the outlet of the filter assembly 200, the air distribution assembly 300 is used to guide the gas filtered by the filter assembly 200, the airflow drive assembly 400 is fixedly disposed at the air outlet of the air distribution assembly 300, the airflow drive assembly 400 is used to drive external air to enter the housing 100 along the airflow channel, flow through the filter assembly 200 and then be discharged to the outside of the housing 100, and the germicidal lamp 500 is installed at the bottom of the installation chamber, the germicidal lamp 500 is located at the center of the bottom of the filter assembly 200, the germicidal lamp 500 is used to sterilize the gas entering the filter assembly 200.

[0045] For example, the cross-section of the housing 100 can be triangular, quadrilateral, pentagonal or hexagonal, etc., and there is no specific limitation here. In this embodiment, the cross-section of the housing 100 is quadrilateral.

[0046] Please see Figure 1 and Figure 2 As shown, the shell 100 has a quadrilateral cross-section, meaning the shell 100 is a cube in shape. The shell 100 has rounded corners to enhance its overall aesthetics. While existing circular air purifier designs can achieve uniform air intake, they have a smaller air handling capacity within the same space. Square air purifiers can increase air handling capacity, but their larger corner angles lead to uneven air intake and higher noise levels. Compared to existing circular air purifiers, the rounded square design of this application has a larger volume in the same horizontal / vertical length within the same space, allowing more air to enter and thus achieving a larger air handling capacity. Compared to square air purifiers, the rounded corners also result in lower noise levels.

[0047] Specifically, the housing 100 can intake air from at least one of its circumferential sides and exhaust air from the top. External air passes through the housing 100 and enters the filter assembly 200. The filter assembly 200 filters the air and then uses the airflow drive assembly 400 to distribute the gas evenly, so that the exhaust air can be evenly discharged to the outside. It can be understood that setting the exhaust at the top can avoid directly blowing air onto the user or stirring up dust on the bottom surface.

[0048] For example, the housing 100 may allow air to enter from one, two, three or four sides of its circumference. In this embodiment, the housing 100 allows air to enter from three sides of its circumference.

[0049] In this embodiment, the germicidal lamp 500 is placed at the bottom, thereby enabling air sterilization in the filter assembly 200 from bottom to top. On the one hand, the wiring is simpler compared to fixing the germicidal lamp 500 to the top of the filter assembly 200. On the other hand, the air distribution assembly 300 can be made detachable, so that the air distribution assembly 300 can be removed, making it convenient to remove and clean the fan 430 in the airflow drive assembly 400.

[0050] In some specific embodiments, the housing 100 includes a circumferential housing 110, a bottom cover 120 is detachably installed at the bottom of the circumferential housing 110, and a top cover 130 is detachably installed at the top of the circumferential housing 110. The circumferential housing 110, the bottom cover 120, and the top cover 130 define an installation chamber, and the connection between the circumferential housing 110 and the bottom cover 120 and the top cover 130 is provided with a rounded corner transition.

[0051] Please continue reading. Figure 1 and Figure 2 As shown, in this embodiment, the circumferential shell 110 and the power connection between the bottom cover 120 and the top cover 130 are all rounded. Specifically, the circumferential shell 110 covers the edges of the bottom cover 120 and the top cover 130, thereby effectively reducing the exposure of the seam between the bottom cover 120 and the top cover 130, thus improving the appearance and aesthetics of the product.

[0052] Furthermore, in this embodiment, a filter assembly 200, an air distribution assembly 300, and an airflow drive assembly 400 are arranged sequentially from bottom to top in the installation chamber. As the airflow drive assembly 400 draws air, a negative pressure is generated in the filter assembly 200. Under the action of air pressure, external air enters the installation chamber through the circumferential shell 110 in the circumferential direction and finally enters the filter assembly 200. When the air enters the filter assembly 200, the gas is filtered and purified by the filter assembly 200, so that the gas in the filter assembly 200 meets the filtration requirements. Under the extraction action of the airflow drive assembly 400, the filtered gas in the filter assembly 200 is discharged to the outside through the top cover 130, thereby completing the filtration of the air.

[0053] In some specific embodiments, the circumferential shell 110 has a rectangular cross-section. The circumferential shell 110 includes a front cover 111 that is detachably mounted on the bottom cover 120. Two side covers 112 are arranged opposite to each other on both sides of the front cover 111. A rear cover 113 connected to the side covers 112 is arranged at a position opposite to the front cover 111. The connection between the side covers 112 and the front cover 111 and the rear cover 113 is provided with rounded corner transition.

[0054] Please continue reading. Figure 1 and Figure 2 As shown, in this embodiment, the edges of the front cover 111, side cover 112 and rear cover 113 are all designed with rounded corners. The purpose is to reduce the gap between two adjacent components, improve the overall aesthetics of the purifier, and also reduce the noise generated by the squeezing and friction between adjacent components during handling or use.

[0055] It should be noted that in this embodiment, the front cover 111, side cover 112, rear cover 113, bottom cover 120, and top cover 130 are all made of plastic injection molding.

[0056] In this embodiment, by providing corresponding grid holes on the two side covers 112 and the rear cover 113, the grid holes on the two side covers 112 and the rear cover 113 form an airflow channel, so that external air can enter the installation chamber and then enter the filter assembly 200. In addition, in order to make the filtered gas evenly discharged through the top cover 130, corresponding mesh holes can also be provided on the top cover 130 to evenly discharge the filtered gas.

[0057] Please see Figure 1 As shown, a second reinforcing plate 600 is provided at the connection between the front cover 111 and the side cover 112. Specifically, the second reinforcing plate 600 is snapped onto the front cover 111, and the second reinforcing plate 600, the front cover 111, and the side cover 112 form a channel for the wiring.

[0058] In some specific embodiments, the side cover 112 is provided with a mounting groove 1121 near the edge of the rear cover 113. The top of the mounting groove 1121 is provided with a limiting groove 1123 communicating with it. A first reinforcing plate 1124 is provided inside the mounting groove 1121. The end of the first reinforcing plate 1124 is located in the limiting groove 1123. At least one first fixing post 1122 is provided on the inner wall of the mounting groove 1121. A first mounting hole 11241 adapted to the first fixing post 1122 is provided on the first reinforcing plate 1124. The first mounting hole 11241 is sleeved on the first fixing post 1122. The first reinforcing plate 1124 is screwed onto the first fixing post 1122 and connected to the side cover 112 by screws passing through the first mounting hole 11241.

[0059] Please see Figure 3 and Figure 4As shown, since the side cover 112 has vent holes for air intake, a large airflow can cause the entire side cover 112 to deform. This can lead to increased gaps at the connections between the side cover 112 and the front cover 111 and rear cover 113, resulting in abnormal noise due to vibration. To improve the overall strength of the side cover 112, a mounting groove 1121 is provided on the inner side of the side cover 112 facing the rear cover 113. The mounting groove 1121 is set along the height direction. Furthermore, a limiting groove 1123 is provided at the top of the mounting groove 1121. Specifically, a first reinforcing plate 1124 made of metal is placed in the mounting groove 1121. The top of the first reinforcing plate 1124 is inserted into the limiting groove 1123 to limit the position of the top of the first reinforcing plate 1124. This ensures that the first reinforcing plate 1124 and the side cover 1122 are properly positioned. If the cover 112 is fully fixedly connected, then multiple first fixing posts 1122 are arranged at intervals on the inner wall of the mounting groove 1121. First mounting holes 11241 that are adapted to the position and size of the first fixing posts 1122 are opened on the first reinforcing plate 1124. When it is necessary to fix the two together, screws can be inserted through the first mounting holes 11241 into the first fixing posts 1122. As the screws are turned, the first reinforcing plate 1124 is fixedly installed in the mounting groove 1121, thereby realizing the fixed connection between the first reinforcing plate 1124 and the side cover 112.

[0060] In some specific embodiments, a fixing plate 1125 is integrally provided at the end of the first reinforcing plate 1124 away from the limiting groove 1123. A second mounting hole 11251 is provided on the fixing plate 1125. A support plate 1126 is provided at the end of the mounting groove 1121 away from the limiting groove 1123. A clearance hole 11261 coaxial with the second mounting hole 11251 is provided on the support plate 1126. The support plate 1126 abuts against the fixing plate 1125. The second fixing post 1211 on the bottom cover 120 passes through the clearance hole 11261 and the second mounting hole 11251 in sequence.

[0061] See Figure 3 , Figure 4 as well as Figure 5As shown, in order to further improve the connection strength between the first reinforcing plate 1124 and the side cover 112 and to achieve the connection between the side cover 112 and the bottom cover 120, a support plate 1126 integrally formed with the side cover 112 is provided at the end of the mounting groove 1121 away from the limiting groove 1123. A fixing plate 1125 is integrally formed at the bottom of the first reinforcing plate 1124, and the fixing plate 1125 abuts against the upper surface of the support plate 1126. In order to connect the fixing plate 1125 and the support plate 1126 with the second fixing post 1211 of the bottom cover 120, a fixing plate 1126 is integrally formed with the side cover 1124. The fixed plate 1125 has a second mounting hole 11251 corresponding to the second fixed post 1211, and the support plate 1126 has a clearance hole 11261 corresponding to the second fixed post 1211 and coaxial with the second mounting hole 11251. Specifically, the second fixed post 1211 passes through the clearance hole 11261 and the second mounting hole 11251 to position the fixed plate 1125 and the support plate 1126, prevent the fixed plate 1125 and the support plate 1126 from moving, and thus connect the support plate 1126 to the bottom cover 120.

[0062] In some specific implementations, the bottom cover 120 includes a first cover 121 and a second cover 122. The first cover 121 and the second cover 122 are separately configured and fixedly connected by screws. Specifically, a second fixing post 1211 is integrally formed on the side of the first cover 121 facing the second cover 122, and the second fixing post 1211 is connected to the outside, so that the fixing plate 1125 and the support plate 1126 can extend into the second fixing post 1211 and pass through it. In practice, after the fixing plate 1125 and the support plate 1126 are connected to the second fixing post 1211, the screws can pass through the second cover 122, the clearance hole 11261 and the second mounting hole 11251 to connect to the second fixing post 1211, thereby fixing the fixing plate 1125 and the support plate 1126 to the second fixing post 1211.

[0063] In this embodiment, the second fixing post 1211 is a screw post, and a corresponding screw post is provided on the second cover 122 at the position of the second fixing post 1211, and the two are connected by screws.

[0064] Please continue reading. Figure 5As shown, a first slot 1212 and a second slot 1213 are provided on the side wall of the first cover 121. The first slot 1212 is located on both sides of the side wall of the first cover 121 and is connected and limited to the rear cover 113 through the first cover 121. The second slot 1213 can trigger the switch installed inside the bottom cover 120, thereby enabling power supply to the germicidal lamp 500 or other components. The first slot 1212 and the second slot 1213 are described in detail below, and will not be elaborated here.

[0065] In some specific embodiments, the rear cover 113 includes a rear upper cover 1131 and a rear lower cover 1132. The rear upper cover 1131 and the rear lower cover 1132 are detachably connected. At least one first insert 11311 is provided at the top edge of the rear upper cover 1131. A third insertion hole 131 is provided at the edge of the top cover 130. The first insert 11311 is located in the third insertion hole 131. First fasteners 11312 are provided at both sides of the rear upper cover 1131. A fastener plate 11201 that engages with the first fastener 11312 is provided at the edge of the side cover 112 near the rear upper cover 1131. First fastener positions 11321 are provided at both sides of the rear lower cover 1132. A second fastener 11202 that engages with the first fastener position 11321 is provided at the edge of the side cover 112 near the rear lower cover 1132.

[0066] Please see Figure 6 and Figure 11 As shown, the upper rear cover 1131 and the lower rear cover 1132 are separate units. The lower rear cover 1132 has a grille. The upper rear cover 1131 and the lower rear cover 1132 are snap-fitted together. Specifically, two first spring tabs 11301 are provided on both sides of the upper rear cover 1131. The two first spring tabs 11301 are spaced apart to form a through-hole. At the through-hole position, the upper rear cover 1131 also has a through-hole 11302 to facilitate the connection between the third insertion hole 131 and the lower rear cover 1132. 2. Connection: On both sides of the rear lower cover 1132, there are integrally formed locking blocks 11303. Specifically, the locking blocks 11303 pass through the through hole 11302 to the through space position. At the through space position, the two first spring pieces 11301 abut against the locking blocks 11303 and deform until the protruding part of the through hole 11302 passes through the through space, so that the first spring pieces 11301 abut against the recessed part of the locking blocks 11303, thereby realizing the locking between the first spring pieces 11301 and the locking blocks 11303.

[0067] It is understandable that the locking block 11303 has a protrusion and a recess. The protrusion abuts against the first spring 11301 first, causing the first spring 11301 to deform and avoid. Then, after the protrusion passes through the through space, the first spring 11301 will lock into the recess, thereby realizing the locking between the upper rear cover 1131 and the lower rear cover 1132.

[0068] Please continue reading. Figure 6 and Figure 10 As shown, when the rear upper cover 1131 is connected to the top cover 130, the first insert 11311 on the top of the rear upper cover 1131 can be inserted into the third insertion hole 131 opened at the edge of the top cover 130, thereby achieving the limiting between the third insertion hole 131 and the rear upper cover 1131. Multiple buckles 11201 are provided at the variable edge of the side cover 112 near the rear upper cover 1131. The buckles 11201 have slots. In order to achieve the connection between the rear upper cover 1131 and the side cover 112, the first buckle 11312 is inserted into the slot of the buckle 11201, thereby achieving the connection between the rear upper cover 1131 and the side cover 112.

[0069] In some specific embodiments, a second insert 11322 is integrally provided at the bottom of the rear lower cover 1132, and the second insert 11322 extends into a first slot 1212 opened on the bottom cover 120. A third insert 11323 is also provided at the bottom of the rear lower cover 1132, and the third insert 11323 extends into a second slot 1213 opened on the bottom cover 120. A fourth insert 11324 is provided at the top of the rear lower cover 1132, and the fourth insert 11324 extends into a fourth slot 302 opened on the side wall of the air distribution component 300.

[0070] Please see Figure 1 as well as Figure 6 As shown, in order to connect the lower rear cover 1132 with the bottom cover 120 and the side cover 112, a second fastening block 11202 is provided at both sides of the side cover 112. During installation, the second insert 11322 at the bottom of the lower rear cover 1132 is first inserted into the first slot 1212, and then the two sides of the lower rear cover 1132 are moved toward the side cover 112, so that the first fastening position 11321 and the second fastening block 11202 are engaged, thereby connecting the lower rear cover 1132 with the bottom cover 120. Specifically, during the movement of the lower rear cover 1132 toward the side cover 112, the third insert 11323 extends into the second slot 1213 to trigger the switch in the bottom cover 120, and the locking block 11303 passes through the through hole 11302 and engages with the first spring piece 11301, thereby connecting the upper rear cover 1131 with the lower rear cover 1132.

[0071] Furthermore, in order to position the top of the rear lower cover 1132, an integrally formed fourth insert 11324 is provided on both sides of the top of the rear lower cover 1132. When the rear lower cover 1132 moves toward the side cover 112 and the first fastener 11321 is engaged with the second fastener 11202, the fourth insert 11324 will also extend into the fourth slot 302 of the air distribution component 300, thereby positioning the top of the rear lower cover 1132 and preventing it from moving.

[0072] In some specific embodiments, the front cover 111, the side cover 112 and the rear cover 113 are all provided with abutment plates 101 on the sides facing the filter assembly 200, and the abutment plates 101 abut against the filter assembly 200.

[0073] Please see Figure 1 , Figure 3 as well as Figure 6 As shown, since the filter assembly 200 is located in the installation chamber, it will shake if its position is not limited. Therefore, abutment plates 101 are provided on the front cover 111, the two side covers 112 and the top cover 130. The abutment plates 101 abut against the filter assembly 200 to limit the position of the filter assembly 200.

[0074] In some specific embodiments, the filter assembly 200 includes a first end cap 210, a filter element 220 is disposed on the first end cap 210, a second end cap 230 is disposed on the end of the filter element 220 opposite to the first end cap 210, and a sealing element 231 is disposed on the second end cap 230.

[0075] Please see Figure 7 As shown, the cross-section of filter element 220 is also rounded, which can reduce the noise caused by the square shape while ensuring a large air handling capacity. Furthermore, filter element 220 and the first end cap 210 are placed on the bottom cover 120. Correspondingly, the bottom surface of the first end cap 210 also has a sealing ring to prevent unfiltered gas from entering the interior of filter element 220 through the gap between the first end cap 210 and the bottom cover 120. Correspondingly, filter element 220 is connected to the air distribution assembly 300 through the second end cap 230 at the top, and the second end cap 230 is provided with a sealing element 231 to achieve sealing. Specifically, the sealing element 231 is a sealing strip, which can be a ring sealing strip, etc.

[0076] During installation, the top of the filter assembly 200 abuts against the air distribution assembly 300, and the connection between the filter assembly 200 and the air distribution assembly 300 is sealed by the sealing element 231; the bottom of the filter assembly 200 abuts against the bottom cover 120, and the connection between the filter assembly 200 and the bottom cover 120 is sealed by the sealing element 231; with the various snap-fit ​​engagements between the housings and the abutment engagements with the filter assembly, the overall structure is stable and well-sealed, which also helps to reduce wind noise.

[0077] For example, filter element 220 is a HEPA filter element, activated carbon filter element, etc.

[0078] In some specific embodiments, the air distribution component 300 includes a housing 310, which has a mounting cavity 301. A fourth slot 302 is provided on the outer side wall of the housing 310. A grid 320 is recessed in the mounting cavity 301 toward the filter component 200, and the ribs of the grid 320 are distributed in an arc shape along the radial direction of the mounting cavity 301. Existing grids are generally horizontally or convexly arranged. Compared with horizontally or convexly arranged structures, the recessed structure of the grid 320 allows for a larger distance between the grid 320 and the fan 430, providing sufficient space for the grid 320 to guide the airflow, reducing noise generation, and thus improving the noise reduction effect.

[0079] See Figure 8 As shown, in order to ensure that the air filtered by the filter assembly 200 enters the airflow drive assembly 400 evenly for driving and exhausting, in this embodiment, the bending direction of the ribs of the grid 320 is the same as the rotation direction of the fan blades of the fan 430, thereby further reducing wind resistance and achieving noise reduction.

[0080] In some specific embodiments, the airflow drive assembly 400 includes a duct housing 410, a bracket 420 is disposed in the duct housing 410, a fan 430 is fixedly disposed on the bracket 420, the duct housing 410 includes an integrally formed circular portion 411 and a square portion 412, and the bracket 420 is disposed in the circular portion 411.

[0081] Please see Figure 9 As shown, the purpose of setting the air duct housing 410 as a combination of circular part 411 and square part 412 is to fix the entire airflow drive assembly 400 at the four corners of the housing 100, and to obtain a larger ventilation volume and maximize the use of the space in the installation room.

[0082] Understandably, the fan 430 is mainly composed of a motor and fan blades. The fan blades are slightly smaller than the diameter of the circular part 411, which facilitates the installation and disassembly of the fan 430. The connection between the circular part 411 and the square part 412 is made with an arc transition.

[0083] Please continue reading. Figure 9 As shown, the bracket 420 includes a plurality of support rods 421 fixedly installed on the inner wall of the square portion 412. A mounting member 422 for mounting the fan 430 is provided at the center of the square portion 412. The fan blades of the fan 430 are located in the circular portion 411. In this embodiment, there are four support rods 421 evenly distributed in the square portion 412. One of the support rods 421 has a wiring channel 4210, and the wiring channel 4210 communicates with the mounting member 422 and the external space of the square portion 412, so that the wire passes through the wiring channel 4210 to the mounting member 422 to provide power to the fan 430.
