[0045] Figure 1 is a schematic diagram of the overall structure of an air purifier provided by some embodiments of the present application. Figure 2 is another schematic diagram of the overall structure of an air purifier provided by some embodiments of the present application. Figure 3 is a sectional view of an air purifier provided by some embodiments of the present application.

[0046] In some examples, referring to Figures 1-3 , some examples of the embodiments of the present application provide an air purifier. The air purifier can include a body 10.

[0047] In some examples, the body 10 can be made of non-metallic materials. For example, the body 10 can be made of hard plastic or engineering plastic.

[0048] In some examples, the body 10 can be made of metallic materials. For example, the body 10 can be made of aluminum alloy, stainless steel, or iron sheet.

[0049] In some examples, referring to Figures 1-3 As shown, the body 10 can have an air inlet area 110. The air inlet area 110 can be arranged at the middle part of the body 10. For example, as shown in the direction of the height (for example, the direction of the z-axis in the middle of the body 10), the air inlet area 110 can be arranged at the middle part of the body 10. Figure 1 As shown in the direction of the height (for example, the direction of the z-axis in the middle of the body 10), the air inlet area 110 can be arranged at the middle part of the body 10. Figure 1 In some examples, the body 10 can be arranged vertically along the direction of the height (for example, the direction of the z-axis in the middle of the body 10). In this way, the air purifier can occupy less space in the horizontal direction, thereby saving indoor space and facilitating the use of the air purifier in a narrow space. The air inlet area 110 can be arranged at the middle part of the body 10 along the direction of the height.

[0050] In some examples, the body 10 can be arranged horizontally. In this way, the space occupied in the vertical direction can be reduced, thereby facilitating the use of the air purifier in a position where the space in the vertical direction is limited. The air inlet area 110 can be arranged at the middle part of the body 10 along the horizontal direction.

[0051] In some examples, the air inlet area 110 can be provided with an air inlet 111. The air inlet 111 can be connected to the inside of the body 10. That is, the air inlet 111 can penetrate the inner and outer walls of the body 10, and the air outside the body 10 can enter the body 10 through the air inlet 111.

[0052] In some examples, referring to Figure 1 As shown, the first side wall 140 of the body 10 can be provided with the air inlet 111.

[0053] In some examples, referring to Figure 2 As shown, the second side wall 150 of the body 10 can be provided with the air inlet 111. The second side wall 150 can be the side wall opposite to the first side wall 140. In this way, the air inlet area 110 can be provided with the air inlets 111 on the first side wall 140 and the second side wall 150, and air can be inhaled into the body 10 from the air inlets 111 on the first side wall 140 and the second side wall 150, thereby increasing the air inlet efficiency of the air purifier and improving the air purification efficiency.

[0054] In some examples, referring to Figure 1 and Figure 2 As shown, the body 10 can have a first air outlet area 120. The first air outlet area 120 can be arranged at one end of the air inlet area 110.

[0055] In some examples of embodiments of this application, the body 10 is arranged vertically as an example. The first air outlet zone 120 may be located at the top of the air inlet zone 110.

[0056] In some examples, the first air outlet zone 120 may be located at the bottom of the air inlet zone 110.

[0057] In some examples, the first air outlet zone 120 may have a first air outlet 121. The first air outlet 121 may be located on one side of the body 10. For example, see reference... Figure 1 and Figure 3 As shown, the first air outlet 121 can be located on the first side wall 140.

[0058] In some examples, the first air outlet zone 120 may have a second air outlet 122. The second air outlet 122 may be disposed opposite to the first air outlet 121 on the other side of the body 10. For example, see reference... Figure 2 and Figure 3 As shown, the second air outlet 122 can be located on the second side wall 150.

[0059] Thus, after air enters the body 10 from the air inlet 110, it can be discharged outward from both sides of the first air outlet 120, namely the first air outlet 121 and the second air outlet 122; this can increase the exhaust volume of the first air outlet 120 and improve the air purification efficiency of the air purifier.

[0060] In some examples, refer to Figure 3 As shown, a first fan 20 can be installed in the first air outlet zone 120. Along the air outlet direction of the first air outlet zone 120 (e.g., ... Figure 3 (As indicated by arrows b and b1), the first blade 210 of the first fan 20 is tilted rearward in the direction of rotation of the first fan 20. For example, referring to... Figure 3 As shown, the first fan 20 can rotate counterclockwise. Figure 3 (in the direction indicated by the middle arrow c), along Figure 3 As indicated by arrow b or arrow b1, the first blade 210 is tilted in the opposite direction to arrow c. That is, the first blade 210 of the first fan 20 can be a vortex-curved blade. This improves the aerodynamic performance of the first fan 20, reduces airflow separation and vortex generation, increases the airflow and air pressure of the first fan 20, and enhances the purification efficiency of the air purifier.

[0061] In some examples, refer to Figures 1-3 As shown, the body 10 may have a second air outlet zone 130. The second air outlet zone 130 may be located at the other end of the air inlet zone 110. For example, with Figure 1 Taking the direction in the middle as an example, the second air outlet zone 130 can be located at the bottom of the air inlet zone 110.

[0062] That is, in some examples of the embodiments of the present application, the body 10 can be from bottom to top the second air outlet area 130, the air inlet area 110, and the first air outlet area 120.

[0063] In some examples, referring to Figure 1 and Figure 3 , the second air outlet area 130 can have a third air outlet 131. The third air outlet 131 can be provided on one side of the body 10. For example, the third air outlet 131 can be provided on the first side wall 140.

[0064] In some examples, referring to Figure 2 and Figure 3 , the second air outlet area 130 can have a fourth air outlet 132. The fourth air outlet 132 can be provided on the other side of the body 10 opposite the third air outlet 131. For example, the fourth air outlet 132 can be provided on the second side wall 150.

[0065] In some examples, referring to Figure 3 , the second air outlet area 130 can be provided with a second fan 30. In some examples of the embodiments of the present application, the second fan 30 can be provided in the same, similar or similar manner as the first fan 20. For details, please refer to the foregoing detailed description of the first fan 20 of the embodiments of the present application, which will not be repeated here.

[0066] According to the air purifier provided by the embodiments of the present application, the first air outlet area 120 is provided at one end of the air inlet area 110, the first fan 20 is provided in the first air outlet area 120, and the first air outlet area 120 has the first air outlet 121 and the second air outlet 122 provided on opposite sides of the body 10; in this way, the first air outlet area 120 can respectively blow air from the first air outlet 121 and the second air outlet 122, increasing the air outlet area of the first air outlet area 120, thereby increasing the air outlet volume of the first air outlet area 120; the second air outlet area 130 is provided at the other end of the air inlet area 110, the second fan 30 is provided in the second air outlet area 130, and the second air outlet area 130 has the third air outlet 131 and the fourth air outlet 132 provided on opposite sides of the body 10; in this way, the second air outlet area 130 can respectively blow air from the third air outlet 131 and the fourth air outlet 132, increasing the air outlet area of the second air outlet area 130, thereby increasing the air outlet volume of the second air outlet area 130. In addition, the first fan 20 is provided with the first fan blade 210 inclined to the rear of the rotation direction of the first fan 20; the second fan 30 is provided with the second fan blade 310 inclined to the rear of the rotation direction of the second fan 30; in this way, the aerodynamic performance of the first fan 20 and the second fan 30 can be improved, the air volume and air pressure can be increased, the noise and vibration during operation of the first fan 20 and the second fan 30 can be reduced, and the efficiency of air purification and filtration can be improved.

[0067] Figure 4 This is an exploded view of the internal structure of an air purifier provided in some embodiments of this application. Figure 5 This is an exploded cross-sectional view of the internal structure of an air purifier provided in some embodiments of this application. Figure 6 yes Figure 3 A magnified view of a portion of point A in the middle.

[0068] In some examples, refer to Figures 4-6 As shown, a first mounting cover 40 may be provided inside the body 10. The first mounting cover 40 may be fixedly connected to the inner wall of the body 10. The first mounting cover 40 may be located between the air inlet zone 110 and the first air outlet zone 120.

[0069] In some examples, refer to Figure 4 and Figure 5 As shown, a first vent 410 may be provided on the first mounting cover 40. The first vent 410 may connect the air inlet area 110 and the first air outlet area 120. In this way, it is convenient for the airflow in the air inlet area 110 to flow to the first air outlet area 120.

[0070] In some examples, refer to Figure 3 As shown, a filter element 112 can be installed in the air intake zone 110. The filter element 112 can block the air inlet 111 of the air intake zone 110. In this way, after the ambient air enters the unit 10, it first flows through the filter element 112, which can filter dust, dirt or other impurities in the air, thereby purifying the air.

[0071] In some examples, refer to Figure 3 As shown, an airflow channel 1121 may be provided inside the filter element 112. The extending direction of the airflow channel 1121 may intersect with the air inlet direction of the air inlet 111. For example, referring to... Figure 3 As shown, the air inlet 111 can be along... Figure 3 Air intake is indicated by the direction shown on the x-axis, and airflow channel 1121 can flow along... Figure 3 Extend in the direction shown by the z-axis.

[0072] In some examples, the airflow channel 1121 may extend through both ends of the filter element 112. In this way, airflow can be discharged within the airflow channel 1121 along both ends of the filter element 112.

[0073] In some examples, refer to Figures 3-5As shown, the air flow channel 1121 can be in communication with the first air vent 410. That is, the air from the outside environment can enter the body 10 from the air inlet 111, then flow in the air flow channel 1121 after being filtered by the filter element 112, and flow to the first air outlet area 120 from the first air vent 410, and then be discharged to the outside environment from the first air outlet 121 and the second air outlet 122 of the first air outlet area 120, so as to realize the purification of the air.

[0074] In some examples, since the air flow channel 1121 penetrates the filter element 112 and is in communication with the first air vent 410, in order to avoid the air entering the body 10 from the air inlet 111 directly entering the first air vent 410 from the top of the filter element 112, the end surface of the filter element 112 towards the first mounting cover plate 40 can be sealingly connected with the first mounting cover plate 40. In this way, the outer side of the filter element 112 can be sealingly isolated from the first air vent 410.

[0075] In some examples, after the filter element 112 and the first mounting cover plate 40 are installed in the body 10, the first mounting cover plate 40 can be tightly pressed on the end surface of the filter element 112, so that the end surface of the filter element 112 is sealingly connected with the first mounting cover plate 40.

[0076] In some examples, a sealing ring can be arranged on the end surface of the filter element 112, and the first mounting cover plate 40 can be tightly pressed on the sealing ring, so that the end surface of the filter element 112 is sealingly connected with the first mounting cover plate 40.

[0077] In the embodiments of the present application, by arranging the first mounting cover plate 40 in the body 10, arranging the first air vent 410 on the first mounting cover plate 40, arranging the filter element 112 in the air inlet area 110, arranging the air flow channel 1121 in the inside of the filter element 112, and arranging the air flow channel 1121 in communication with the first air vent 410, and sealingly connecting the end surface of the filter element 112 with the first mounting cover plate 40, the air from the outside environment entering the body 10 from the air inlet 111 can be completely filtered by the filter element 112, and then enter the first air outlet area 120 from the first air vent 410 through the air flow channel 1121. The air can be prevented from directly entering the first air vent 410 from the gap between the end surface of the filter element 112 and the first mounting cover plate 40, and the efficiency of air purification and filtration is improved.

[0078] In some examples, with reference to Figures 4-6 As shown, the end surface of the filter element 112 towards the first mounting cover plate 40 can be provided with a first filter element end cover 113. The first filter element end cover 113 can be fixedly connected with the filter element 112.

[0079] In some examples, the first filter element end cover 113 can be bonded with the filter element 112. The first filter element end cover 113 can play a role of supporting and strengthening the filter element 112. It is convenient to maintain the structural shape of the filter element 112, and it is convenient to transport, store and disassemble and replace the filter element 112.

[0080] In some examples, one of the first filter element end cover 113 and the first mounting cover plate 40 can be provided with a first sealing groove 401.

[0081] In some examples, the first sealing groove 401 can be provided with a first sealing ring 402. The thickness of the first sealing ring 402 can be greater than the depth of the first sealing groove 401. In this way, at least part of the first sealing ring 402 can protrude from the first sealing groove 401.

[0082] In some examples, the first sealing ring 402 can be in sealing abutment with the other one of the first filter element end cover 113 and the first mounting cover plate 40.

[0083] In some examples, the first sealing groove 401 can be provided on the first filter element end cover 113. At this time, the first sealing ring 402 can be in sealing abutment with the first mounting cover plate 40.

[0084] In some examples, the first sealing groove 401 can be provided on the first mounting cover plate 40. At this time, the first sealing ring 402 can be in sealing abutment with the first filter element end cover 113.

[0085] In some examples, the first sealing ring 402 can be embedded in the first sealing groove 401.

[0086] In some examples, the first sealing ring 402 can be bonded in the first sealing groove 401.

[0087] In some examples of the embodiments of the present application, the first filter element end cover 113 is arranged on the end surface of the filter element 112 facing the first mounting cover plate 40. In this way, the first filter element end cover 113 can play a role of supporting the filter element 112 and can ensure the strength of the filter element 112. The first sealing groove 401 is arranged on one of the first filter element end cover 113 and the first mounting cover plate 40, and the first sealing ring 402 is arranged in the first sealing groove 401.
