DETAILED DESCRIPTION

[0024] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] The components of the embodiments of the present application generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0026] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0027] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] Refer to the following Figures 1-9 A portable blender blade holder structure according to some embodiments of the present application is described.

[0030] The utility model provides a portable blender blade holder structure, comprising a blade disc 1, a rotating shaft 2 and a driven seat 3. The blade disc 1 is an integrated structure, with the middle portion being recessed upward and extending to form a mounting cavity 4, making component installation simpler, and the overall structure more beautiful and easy to clean and maintain. The edge of the blade disc 1 is turned up to form a cylindrical wall 5, on which a first long protrusion 9 distributed in the direction of the thread is provided. The function of the first protrusion 9 here is to engage with the thread of the upper cup body 22, thereby connecting the blade disc 1 and the cup body 22. A first sealing ring 10 is provided between the mounting cavity 4 in the middle of the blade disc 1 and the edge wall 5. A third protrusion 6 and a first through hole 7 are provided near the edge of the blade disc 1. The first sealing ring 10 is provided with an upward hollow sleeve 11 and a downward solid fourth protrusion 12. The hollow sleeve 11 is engaged with the third protrusion 6 of the blade disc, and the fourth protrusion 12 is engaged with the first through hole 7 of the blade disc. In one embodiment, the fourth solid protrusion 12 pointing downward just rests against the spring mechanism of the safety switch at the base of the blender. When a sufficiently large external force acts on the first sealing ring 10 and is transmitted to the spring mechanism through the fourth protrusion 12, the spring contracts, the safety switch is turned on, and the motor drive circuit is connected. At this time, if the motor drive button is pressed, the motor is powered on and works. When the external force disappears, the spring recovers its deformation, pushing up the fourth protrusion 12, and the safety switch is disconnected. At this time, even if the motor drive button is pressed, the motor cannot be powered on and works. The hollow sleeve 11 pointing upward acts as a handle, making it convenient to remove the first sealing ring 10 when cleaning. The gap between the third protrusion 6 and the cylindrical wall 5 at the edge of the cutter head 1 is small, which prevents fingers from reaching in and accidentally touching the safety switch.

[0031] Preferably, a second through-hole 8 is defined at the top of the mounting cavity 4, and a second protrusion 21 is defined on the inner wall of the bottom of the mounting cavity 4. The second protrusion 21 engages with the mixer base 23. The driven seat 3 is a hollow structure, with a limit plate 13 mounted therein. The limit plate 13 has an axial hole 14 defined in its center. The driven seat 3 has a central screw hole 15. The upper end of the driven seat is cylindrical, with a hollow center, and the lower end is a disc. A polyhedron-shaped fifth protrusion 16 is defined at the bottom.

[0032] Preferably, a bearing 17 is tightly mounted in the middle of the rotating shaft 2. A third sealing ring 29 is provided at the upper end of the bearing 17, and a reinforcing sleeve 18 is then mounted thereon. The reinforcing sleeve 18 is tightly fitted within the mounting cavity 4, making the connection between the mounting cavity 4, the rotating shaft 2, and the bearing 17 more secure and increasing the strength of the overall structure. The upper end of the rotating shaft 2 extends from the second through hole 8, on which a gasket 19 is mounted, and then connected to the mixing blade 24. The lower end of the rotating shaft 2 passes through the limit plate 13 and is threadedly connected to the screw hole 15 of the driven seat 3. A certain space exists between the limit plate 13 and the bearing 17, which is filled by the gasket 20. The mixing blade 24 includes a wing root 25 and a first blade wing 26 and a second blade wing 27 extending outward from the periphery of the wing root. The structure is simple, reducing production costs.

[0033] The blender blade holder in this technical solution is an independent detachable structure, and has the advantages of simple and reasonable structure, high strength, beautiful appearance, easy cleaning and maintenance, etc., which improves user experience and safety and reduces production costs.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
