Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to an installation structure for a mixing assembly. Background Technology

[0002] Traditional blenders typically include a main unit, a mixing assembly, and a cup body. The mixing assembly includes a cup lid, a drive shaft that rotates in the middle of the cup lid, and a cutting blade located at the lower end of the drive shaft and inside the cup body. The mixing cup body forms a mixing chamber. The main unit drives the cutting blade located in the mixing chamber to mix and cut the materials in the mixing chamber, such as crushing carrots, tomatoes, purple cabbage, apples, and other fruits and vegetables into a puree or making fruit and vegetable juice.

[0003] To facilitate the removal of the mixing assembly for cleaning the cutting blades, the main unit and the mixing assembly are connected by a detachable elastic fastening assembly. In the existing technology, this elastic fastening assembly generally has two design methods. One is to use elastic plastic fasteners, which are prone to breakage and have a short service life. The second is to use a transverse compression spring as the elastic element. The spring force pushes against a fastener that can move horizontally along the radial direction to connect the cup lid shell of the main unit and the mixing assembly. This structure also has certain problems. Since the cup lid shell and the main unit shell are injection molded along the vertical direction, it is difficult to integrally mold the horizontally arranged mounting posts for installing the compression spring on the main unit shell or the cup lid shell. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an installation structure for a stirring component that facilitates the disassembly of the main unit and the stirring component and has a long service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] An installation structure for a stirring assembly includes a main housing and a cup lid housing. The upper end of the cup lid housing is provided with a cylindrical body, and the lower end of the main housing is inserted into the cylindrical body. A locking groove is provided on the inner side wall of the cylindrical body. A movable component is installed on the main housing. The movable component has a locking part that engages with the locking groove and an exposed button part. When the button part is pressed, the locking part disengages from the locking groove. A torsion spring is provided inside the main housing, which can drive the movable component to reset by elastic force so that the locking part engages with the locking groove.

[0007] In a preferred embodiment of this utility model, the movable component further includes a vertical plate located inside the main housing, the buckle portion and the button portion are integrally connected to the vertical plate, the main housing is provided with a buckle hole and a button hole, the buckle portion passes through the buckle hole, and the button portion passes through the button hole.

[0008] In a preferred embodiment of this utility model, there are two movable parts, which are symmetrically arranged at the front and rear of the main housing. The back of each movable part is provided with a positioning groove. The torsion spring includes an annular torsion spring body and two torsion arms. Each torsion arm includes a long rod segment connected to the torsion spring body and a short rod segment connected to the long rod segment. A bend is formed between the long rod segment and the short rod segment. The bend of each torsion arm is engaged in a corresponding positioning groove.

[0009] In a preferred embodiment of this utility model, the back of the movable component is provided with a first groove that mates with the short rod segment and a second groove that mates with the long rod segment.

[0010] In a preferred embodiment of this utility model, an axial torsion spring mounting rod is provided inside the main housing, and the torsion spring body is fitted onto the torsion spring mounting rod.

[0011] The beneficial effects of this utility model are as follows: When the mixer using the above-mentioned stirring assembly installation structure needs to separate the main unit and the stirring assembly, the buttons on both movable parts can be pressed simultaneously. At this time, both locking parts will disengage from their corresponding locking slots, and then the main unit can be lifted upwards to separate the main unit and the stirring assembly, which is convenient and quick. In addition, using torsion springs as the elastic reset elements for the two movable parts ensures a long service life and eliminates the need for a horizontal mounting rod on the motor housing, facilitating the injection molding of the motor housing and the cup lid.

The main unit 100 includes a main unit housing 1 and a motor 6 disposed within the main unit housing 1. The mixing assembly 200 includes a cup lid shell 2, a drive shaft 71, and a cutting blade 72 disposed at the lower end of the drive shaft 71 and located inside the cup body 300. A cylindrical body 21 is disposed in the middle of the cup lid shell 2, and the drive shaft 71 is rotatably mounted in the middle of the cylindrical body 21 via bearings. The upper end of the cup body 300 is detachably connected to the lower end of the cup lid shell 2, the upper end of the drive shaft 71 is detachably connected to the motor 6, and the cylindrical body 21 on the cup lid shell 2 is detachably connected to the lower part of the main unit housing 1.

[0021] Preferably, the cup lid shell 2 and the main body shell 1 are connected by the following structure: the lower end of the main body shell 1 is inserted into the cylinder 21, the inner side wall of the cylinder 21 is provided with a buckle groove 211, the main body shell 1 is equipped with a movable part 3, the movable part 3 has a buckle part 31 that engages in the buckle groove 211 and an exposed button part 32, when the button part 32 is pressed, the buckle part 31 is disengaged from the buckle groove 211, and the main body shell 1 is provided with a torsion spring 4 that can drive the movable part 3 to reset by elastic force so that the buckle part 31 engages in the buckle groove 211.

[0022] Specifically, the movable component 3 also includes a vertical plate 33 located inside the main housing 1. The latching part 31 and the button part 32 are integrally connected to the vertical plate 33. The main housing 1 is provided with a latching hole 101 and a button hole 102. The latching part 31 passes through the latching hole 101, and the button part 32 passes through the button hole 102. There are two movable components 3, which are symmetrically arranged at the front and rear of the main housing 1. The back of the movable component 3 is provided with a positioning groove 301. The torsion spring 4 includes an annular torsion spring body 41 and two torsion arms 42. The torsion arm 42 includes a long rod segment 401 connected to the torsion spring body 41 and a short rod segment 402 connected to the long rod segment 401. A bend 403 is formed between the long rod segment 401 and the short rod segment 402. The bend 403 of each torsion arm 42 is engaged in a corresponding positioning groove 301.

[0023] When it is necessary to separate the main unit 100 and the stirring assembly 200, the button portions 32 of both movable parts 3 can be pressed simultaneously.
