When the purifier 100 is working, the static pressure inside the purifier 100 can be increased by setting the guide vane assembly 120, and the purification efficiency of the purifier 100 can be improved.

[0050] The guide vane assembly 120 can guide the airflow in the purifier 100, thereby increasing the air volume output by the purifier 100 and improving the purification efficiency of the purifier 100 on the surrounding environment.

[0051] Furthermore, by providing the guide vane assembly 120, the flow rate of the airflow can be increased, the static pressure inside the purifier 100 can be increased, and the resistance of the airflow flowing in the purifier 100 can be improved.

[0054] Specifically, the ratio H2 / H1 of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction may be 0.52, the ratio H2 / H1 of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction may be 0.56, the ratio H2 / H1 of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction may be 0.58, the ratio H2 / H1 of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction may be 0.61, and the ratio H2 / H1 of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction may be 0.68.

[0055] Specifically, when the ratio H2 / H1 of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction can be 0.61, the static pressure of the power pack in the purifier 100 can be further increased, thereby improving the ability to overcome resistance in the purifier 100, increasing the axial gas flow rate in the purifier 100, and accelerating the flow rate of the airflow through the filter, thereby increasing the exchange rate between the filter element and the air, and improving the use effect of the purifier 100.

[0059] Furthermore, the guide vanes 126 extending in an arc shape can increase the contact area between the airflow and the guide vanes 126 , thereby improving the diffusion effect of the airflow and facilitating the purified airflow to enter the surrounding environment.

[0060] Furthermore, the arc-shaped extension of the guide vane 126 can enhance the rigidity and stability of the guide vane 126 , reduce vibration, reduce noise, and improve the use effect of the purifier 100 .

[0061] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0062] In the cross section of the guide vane 126 , a tangent line of an edge of the guide vane 126 close to the inside of the housing 110 is a first tangent line 130 , and an angle between the first tangent line 130 and the first direction is greater than or equal to 45 degrees and less than or equal to 56 degrees.

[0063] In this embodiment, within the cross section of the guide vane 126, the tangent of the edge of the guide vane 126 at one end close to the inside of the shell 110 is a first tangent 130, and the angle between the first tangent 130 and the first direction is greater than or equal to 45 degrees and less than or equal to 56 degrees, which can improve the airflow guiding effect of the guide vane 126, and can also improve the resistance of the purifier 100 when driving the airflow by optimizing the size of the guide vane 126, thereby increasing the axial speed of the purifier 100 and thereby increasing the flow rate of the airflow, thereby increasing the exchange speed of the purifier 100 with the external air and thereby improving the purification efficiency.

[0064] Specifically, the angle between the first tangent line 130 and the first direction is B1.

[0065] Specifically, the angle B1 between the first tangent line 130 and the first direction is greater than or equal to 45 degrees and less than or equal to 56 degrees.

[0066] Specifically, when the angle B1 between the first tangent 130 and the first direction is 51 degrees, the inlet installation angle of the guide vane 126 can be limited to improve the resistance of the purifier 100 when driving the airflow, increase the axial speed of the purifier 100, and thus increase the flow rate of the airflow.

[0069] In this embodiment, in the cross section of the guide vane 126, the tangent of the edge of the guide vane 126 at one end close to the outside of the shell 110 is the second tangent 134, and the angle between the second tangent 134 and the first direction is greater than or equal to 0 degrees and less than or equal to 16 degrees. By limiting the angle between the tangent of the edge of the guide vane 126 at one end close to the outside of the shell 110 and the first direction, the outlet installation angle of the guide vane 126 is optimized, the boost effect of the guide vane 126 is improved, and the resistance capacity of the driving airflow in the purifier 100 is improved, the axial speed of the purifier 100 is increased, and the flow rate of the airflow is increased, which can increase the exchange speed of the purifier 100 with the external air, thereby improving the purification efficiency.

[0086] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0087] The purifier 100 further includes a driving component 170 , a mounting end 172 of the driving component 170 is connected to the bracket 124 , and a driving end 174 of the driving component 170 is connected to the impeller 164 , and can drive the impeller 164 to rotate.

[0088] In this embodiment, the purifier 100 further includes a driving component 170, a mounting end 172 of the driving component 170 is connected to the bracket 124, and a driving end 174 of the driving component 170 is connected to the impeller 164, and can drive the impeller 164 to rotate.

[0089] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0090] The purifier 100 further includes a collector 180 and a mesh cover 190 . The collector 180 is connected to the volute 162 and is located on a side of the impeller 164 close to the air inlet passage 152 ; the mesh cover 190 is disposed on the collector 180 .

[0091] In this embodiment, the purifier 100 further includes a collector 180 and a mesh cover 190. The collector 180 is connected to the volute 162 and is located on the side of the impeller 164 close to the air inlet channel 152 to achieve the installation and fixation of the collector 180, so that the collector 180 can guide the air entering the air inlet channel 152 and evenly introduce it into the fan, which can reduce the unevenness of the airflow, reduce the flow loss of the airflow, and improve the purification efficiency of the purifier 100. The mesh cover 190 is arranged on the collector 180 to achieve the installation and fixation of the mesh cover 190, so that the mesh cover 190 can filter impurities in the air, avoid entering the impeller 164 and causing damage to the impeller 164, and extend the service life of the purifier 100.

[0092] Specifically, when the purifier 100 is working, the air to be purified enters the purifier 100 through the air inlet grille 140, purifies the air through the filter component 150, and then passes through the mesh cover 190, the collector 180, the volute 162, the impeller 164, the guide vane 126, and finally discharges the purified air through the air outlet grille 165, and the cycle is repeated to achieve the purpose of purifying the air. The driving component 170 mainly provides the driving force for the rotation of the impeller 164. The rotation of the impeller 164 can form a high negative pressure area near the impeller 164, and then form a pressure difference between the air inlet grille 140 and the impeller 164, so that the air can be sucked in for purification, thereby improving the purification effect of the purifier 100.

[0093] Specifically, Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, area D is an area in the purifier 100 where the guide vane assembly 120 is provided. By setting the ratio of the height of the guide vane 126 in the first direction to the height of the frame 122 in the first direction to 0.61, setting the angle B1 between the first tangent 130 and the first direction to 51 degrees, setting the angle between the second tangent 134 and the first direction to 11 degrees, and setting the ratio of the width of the guide vane 126 in the second direction to the height of the frame 122 in the first direction to 0.06, the size of the guide vane assembly 120 can be optimized to ensure the air guiding efficiency of the guide vane 126 while reducing the resistance of the guide vane assembly 120 to the airflow, increasing the static pressure of the power pack in the purifier 100, and thereby increasing the ability of the purifier 100 to overcome the resistance, increasing the axial speed of the purifier 100, accelerating the airflow, and increasing the exchange rate of the purifier 100 with the outside air. By increasing the output air volume of the purifier 100, the purification effect of the purifier 100 on the surrounding environment can also be improved.

[0094] like Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, in the comparative example of the present invention, the ratio of the guide vane height to the frame height of the purifier has no limit range, and the inlet installation angle and the outlet installation angle of the guide vane are not designed. The simulation results obtained by the simulation test of the purifier in the comparative example are as follows Fig.10 and Fig.11 As shown, area C is the area where the guide vane assembly is set on the purifier in the comparative example. The air flow velocity in this area is lower than the air flow velocity in area D in the present application. It can be seen that by limiting the size range of the guide vanes, the air exchange speed can be increased and the purification effect can be improved. The present application can increase the air volume of the purifier and reduce noise. Compared with the original guide vanes, the flow rate of the present application can be increased by 7% and the static pressure efficiency can be increased by 10%.
