DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4 , an embodiment of the present utility model discloses a fixing structure for a blender, comprising a cup body 1 and a first connecting member 2 provided under the cup body 1, a stirring blade 3 and a rotating shaft 4 for driving the stirring blade 3 to rotate are provided in the cup body 1, a bearing 5 is provided on the outside of the rotating shaft 4, a fixing member 6 is provided between the bearing 5 and the bottom of the cup body 1 and the first connecting member 2, a through hole 61 is provided in the center of the fixing member 6, the rotating shaft 4 extends to the outside of the through hole 61 and is connected to the stirring blade 3, at least one external thread 631 and at least one flat portion 632 are provided on the outer wall of the fixing member 6, an internal thread 21 adapted to the external thread 631 is provided on the inner wall of the first connecting member 2, and the fixing member 6 is threadedly connected to the first connecting member 2.

[0021] The present invention is applied to a blender. Specifically, the blender includes a base body, a driving mechanism is provided in the base body, and the driving mechanism is used to drive the stirring blade 3 in the cup body 1 to rotate, wherein the fixing member 6 is installed in the middle of the cup body 1 and the first connecting member 2, and a through hole 61 is provided in the center of the fixing member 6, a bearing 5 is fixedly installed on the inner side thereof, and a rotating shaft 4 is fixed on the inner side of the bearing 5. Through this structure, the stirring blade 3 is fixed in the cup body 1, which is convenient for the driving mechanism below to drive the rotating shaft 4 to rotate, thereby driving the stirring blade 3 to rotate, so as to stir the liquid in the cup body 1 ; At least one external thread 631 and at least one flat portion 632 are provided on the outer wall of the fixing member 6, and an internal thread 21 adapted to the external thread 631 is provided on the inner wall of the first connecting member 2. The external thread 631 provided on the fixing member 6 is used for threaded connection with the first connecting member 2, and the flat portion 632 provided on the fixing member 6 prevents the fixing member 6 and the first connecting member 2 from rotating left and right when the two are threadedly connected, thereby avoiding loose components that affect the use of subsequent equipment. It can only be disassembled when the staff applies external force, which is also convenient for subsequent cleaning of the equipment.

[0022] Furthermore, the fixing member 6 includes a top block and a connecting portion 62 and a top block 63 provided below the top block. The top block is formed at the top of the fixing member 6 extending to the bottom surface of the cup body 1. The external thread 631 and the flat portion 632 are located on the connecting portion 62 and the top block 63. The top block is located above the bottom surface of the cup body 1 to prevent the fixing member 6 from falling off the cup body 1.

[0023] Furthermore, the connecting portion 62 has a top block; a first receiving groove 64 is provided on one side of the connecting portion 63 near the top block, and a first sealing member 7 is provided in the first receiving groove 64. The first sealing member 7 is used to maintain the sealing between the fixing member 6 and the cup body 1, preventing liquid from leaking from the connection gap and affecting the use of the device. At the same time, the first sealing member 7 can also enhance the stability of the fixing member 6 when connected to the cup body 1.

[0024] Furthermore, the top block has a truncated cone shape, which facilitates liquid to slide down from its oblique edge, thereby preventing liquid from accumulating in the component and causing device corrosion.

[0025] Furthermore, the outer wall of the fixing member 6 is provided with at least two external threads 631 and at least two flat portions 632, with the external threads 631 being arranged perpendicularly adjacent to the flat portions 632. The multiple flat portions 632 provided on the fixing member 6 prevent the fixing member 6 and the first connecting member 2 from rotating left or right when the fixing member 6 is threadedly connected, thus preventing loosening of the components that could affect subsequent use of the device. The fixing member 6 can only be disassembled by applying external force, which also facilitates subsequent cleaning of the device.

[0026] Furthermore, an oil seal 8 is provided in the fixing member 6, which is sleeved on the outer side of the rotating shaft 4 and located between the bearing 5 and the through hole 61. The oil seal 8 prevents liquid from seeping from the through hole 61 onto the bearing 5, thereby avoiding damage to the equipment.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
