[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0027] like Figures 1 to 6As shown, this application provides an impeller and impeller assembly for an air purifier, including: an impeller body 100, including a base plate 10, a drive shaft 20, blades 30 and a connecting ring 40, a mounting seat 50 is installed inside the base plate 10, and the blades 30 are located in the middle of the base plate 10 and the connecting ring 40; an assembly assembly 60 is located at the connection between the mounting seat 50 and the drive shaft 20, including a positioning groove 61 opened on the outside of the drive shaft 20, a moving hole 62 is opened at the upper end of the mounting seat 50, a positioning pin 64 is provided inside the moving hole 62, and a pull block 65 is installed on one side of the positioning pin 64.
[0028] After adopting the above technical solution, since the assembly component 60 is located at the connection between the mounting base 50 and the drive shaft 20, the assembly component 60 can be used for quick installation when installing the drive shaft 20 between the mounting base 50 and the mounting base 50. This solves certain shortcomings in actual use: First, the installation efficiency is low: the nut needs to be rotated multiple times with tools such as wrenches, and the disassembly also requires the reverse operation, which is time-consuming and the operating space is limited; Second, the connection reliability is poor: long-term vibration can easily cause the thread pair to strip, resulting in eccentric vibration of the shaft system and a high failure rate of stripping.
[0029] It should be noted that during the installation of the substrate 10, the mounting base 50 is inserted along the outside of the drive shaft 20, causing the drive shaft 20 to be pressed along the bottom of the positioning pin 64, which in turn compresses the positioning pin 64 along the inside of the moving hole 62, driving the limiting block 66 to move along the inside of the limiting groove 63. At the same time, the support spring 67 is compressed. At this time, the drive shaft 20 continues to move along the inside of the mounting base 50 until the positioning groove 61 and the positioning pin 64 are aligned. Under the elastic potential energy of the support spring 67, the positioning pin 64 is ejected, causing the positioning pin 64 to be inserted into the inside of the positioning groove 61. At this time, the limiting pin 70 and the slot 80 are aligned, fixing the substrate 10 on the outside of the drive shaft 20.
[0030] Similarly, when disassembling the drive shaft 20 from the mounting base 50, by pulling the two sets of pulling blocks 65, the pulling blocks 65 drive the positioning pin 64 to move along the inside of the moving hole 62 and the positioning groove 61, and drive the limiting block 66 to move along the inside of the limiting groove 63 until the compression trajectory of the support spring 67 reaches the end point. At this time, the positioning pin 64 disengages from the inside of the positioning groove 61, thereby disengaging the drive shaft 20 along the inside of the mounting base 50, thereby disengaging the base plate 10 from the outside of the drive shaft 20, and thus quickly disassembling the base plate 10.
[0031] In an optional embodiment, the mounting base 50 has a through hole in the middle that is adapted to the drive shaft 20. The mounting base 50 is fixedly connected to the substrate 10, which facilitates the insertion of the drive shaft 20 along the through hole and the installation of the substrate 10 and the mounting base 50 on the outside of the drive shaft 20.
[0032] In one optional embodiment, the number of blades 30 is several groups and they are arranged in an array. The blades 30 are fixedly connected to the substrate 10 and the connecting ring 40 respectively, which facilitates the connection and stability of the impeller during subsequent rotation.
[0033] In an optional embodiment, two sets of limiting pins 70 are connected to the bottom of the outer side of the drive shaft 20 near the positioning groove 61, and the limiting pins 70 are welded to the drive shaft 20. The bottom of the substrate 10 near the through hole has a groove 80 that matches the limiting pins 70, and the groove 80 is connected to the through hole, so as to facilitate positioning the limiting pins 70 and the groove 80. The limiting pins 70 are inserted into the groove 80 to ensure that the drive shaft 20 has a limiting and stabilizing effect when driving the substrate 10 to rotate, and to prevent the substrate 10 from shifting position.
[0034] In one optional embodiment, the number of positioning grooves 61 is two sets and they are symmetrically distributed. The positioning grooves 61 have a rectangular structure, which facilitates alignment and positioning with the positioning pins 64 and ensures that there is no rotation between the substrate 10 and the drive shaft 20.
[0035] In one optional embodiment, the number of movable holes 62 is two sets and symmetrically distributed. A limiting groove 63 is provided on the inner side of the movable hole 62, and the number of limiting grooves 63 is twice the number of movable holes 62, so as to facilitate the insertion and removal of the positioning pin 64.
[0036] In an optional embodiment, the positioning pin 64 is fixedly connected to the pull block 65, the pull block 65 is adapted to the moving hole 62, the outer side of the positioning pin 64 is fixedly connected to the limiting block 66, and the limiting block 66 is adapted to the limiting groove 63. A support spring 67 is provided between the limiting block 66 and the limiting groove 63, and the number of support springs 67 is equal to the number of limiting blocks 66. The positioning pin 64 can be driven to disengage from the inside of the positioning groove 61 by the pull block 65. At the same time, under the support of the support spring 67, the positioning pin 64 can be fixed inside the positioning groove 61 to ensure the stability between the mounting base 50 and the drive shaft 20.
