Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, and particularly relates to an air purifier with a flow guide plate. Background Art

[0002] In the prior art, a flow guide plate is not provided at the air outlet of the air purifier. When the width of the air outlet is relatively wide, air cannot be distributed in the entire width direction of the air outlet, which results in a relatively narrow effective width of the air outlet (i.e., a small air outlet coverage area). In view of the above technical problems, the present application proposes an air purifier with a flow guide plate, which can guide the airflow at the air outlet of the air purifier, so as to be evenly distributed in the entire width direction of the air outlet, and improve the air outlet coverage area.

[0003] It can be seen that the prior art still needs to be improved. Summary of the Utility Model

[0004] In view of the deficiencies of the above prior art, the purpose of the present utility model is to provide an air purifier with a flow guide plate, aiming to solve the technical problem that the air outlet air of the air purifier in the prior art cannot be evenly distributed in the entire width direction of the air outlet.

[0005] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0006] An air purifier with a flow guide plate includes a housing, a wind wheel, and a wind guide plate. An air outlet is provided on the housing, and wind guide strips are provided on the wind guide plate; a streamlined flow guide plate is provided at the outlet end of the wind guide plate, and the outlet end of the flow guide plate extends to the air outlet, and the length of the flow guide plate is not less than the length of the air outlet.

[0007] Further, in the air purifier with a flow guide plate, the outlet end of the wind guide plate is tangent to the inlet end of the flow guide plate.

[0008] Further, in the air purifier with a flow guide plate, one flow guide plate is correspondingly provided for each wind wheel, and the specifications of each flow guide plate are the same.

[0009] Further, in the air purifier with a flow guide plate, each flow guide plate is respectively provided with a plurality of counterbores.

[0010] Further, in the air purifier with a flow guide plate, an installation seat is provided at the outlet end of the wind guide plate, and connection holes are provided on the installation seat. The number of connection holes is equal to and corresponds to the number of counterbores one by one.

[0011] Beneficial effects: The present utility model provides an air purifier with a flow guide plate. Compared with the prior art, since a flow guide plate is provided at the air outlet, the air blown out by the air wheel is guided by the flow guide plate and the flow guide strips to the flow guide plate. Due to the wall attachment effect of the air flow, a part of the air will move along the surface of the flow guide plate after reaching the flow guide plate, so that the discharged air will cover the entire width direction of the air outlet, improving the air outlet effect.

[0017] The present utility model provides an air purifier with a flow guide plate. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Please refer to Figures 1 to 5 , the present utility model provides an air purifier with a flow guide plate. The drawings are only used to explain the structural principle and are not in proportion to the actual product. The drawings only show the structures related to the inventive points of the present application, and some conventional structures (such as: air inlet, filter, etc.) are not specifically shown. To facilitate observing the internal structure, Figure 1 and Figure 2 do not show the front plate of the housing and the grille plate at the air outlet.

[0019] An air purifier with a flow guide plate includes a housing 1, an air wheel 4, and a flow guide plate 2. An air outlet 100 is provided on the housing, and flow guide strips 3 are provided on the flow guide plate; a streamlined flow guide plate 5 is provided at the outlet end of the flow guide plate, and the outlet end ( Figure 5 the perspective is the bottom end) of the flow guide plate extends to the air outlet, and the length of the flow guide plate is not less than the length of the air outlet ( Figure 2 L in

[0020] When there is more than one deflector, the length of the above-mentioned deflector refers to the sum of the lengths of all deflectors, that is: the deflector should be long enough to obtain the guiding effect of the deflector at every place in the length direction of the air outlet.

[0021] Further, the outlet end of the air guide plate is tangent to the inlet end of the deflector (as Figure 5 shown in the state). This setting makes the connection between the air guide plate and the deflector natural and will not cause additional resistance to the air flow.

[0022] Further, one deflector 5 is correspondingly arranged for each air impeller 4, and the specifications of each deflector are the same. This setting makes the deflectors interchangeable, and different air purifiers can select the number of specific deflector units according to the actual situation. As shown in the appendix Figure 1 shown, there are two air impellers in total, and one deflector is correspondingly arranged for each air impeller.

[0023] As Figure 4 shown, further, each deflector 5 is respectively provided with a plurality of counterbores 50. By providing the counterbores, it is convenient for the connection between the deflector and the air guide plate.

[0024] Further, the outlet end of the air guide plate is provided with a mounting seat 21, and the mounting seat is provided with connection holes 210. The number of connection holes is equal to and corresponds one by one to the number of counterbores. By providing the mounting seat, it is convenient for the connection with the deflector. During actual assembly, a bolt or screw (not shown in the figure) is respectively inserted into each counterbore 50 and screwed into the corresponding connection hole 210, and will not protrude above the deflector, so as not to affect the normal flow of air.

[0025] Since a deflector is provided at the air outlet, the air blown out by the air impeller is guided by the air guide plate and the air guide strip to the deflector. Due to the wall attachment effect of the air flow, part of the air will move along the surface of the deflector after reaching the deflector, so that the discharged air will cover the entire width direction of the air outlet (as Figure 5 shown by the arrows). Figure 5 The dotted line 9 in Figure 5 represents the grille at the air outlet, and

[0026] the arrows in Figure 5 represent the air flow direction. It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution of the present invention and its inventive concept, and all such changes or substitutions should fall within the protection scope of the present invention.
