[0005] To address the technical problems existing in the background art, this utility model proposes a quick-installation structure for the battery pack of a stirrer.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A quick-installation battery pack structure for a stirrer includes a stirrer body, a stirring head connected to the end of the stirrer body, a drive assembly for driving the stirring head to rotate inside the stirrer body, and a detachable battery pack snapped onto the stirrer body.

[0008] The battery pack has a snap-fit ​​protrusion, and the stirrer body has a snap-fit ​​groove for inserting the snap-fit ​​protrusion. The snap-fit ​​protrusion is rotated and limited along the snap-fit ​​groove so that the battery pack is snapped onto the stirrer body and forms an electrical connection.

[0009] Preferably, a connecting boss is formed on the stirrer body, and a connecting groove is formed at the bottom of the battery pack for the connecting boss to be inserted. The snap-fit ​​protrusion is formed on the groove wall of the connecting groove, and the snap-fit ​​groove is formed on the outer periphery of the connecting boss. With the above improvements, during the installation of the battery pack, the connecting boss is placed into the connecting groove, so that the snap-fit ​​protrusion in the connecting groove is placed into the snap-fit ​​groove on the outer periphery of the connecting boss, and the battery pack is rotated to snap the battery pack onto the stirrer body, thereby achieving rapid installation of the battery pack.

[0010] Preferably, a positioning protrusion is provided in the snap-fit ​​groove, and a positioning port is formed on the snap-fit ​​protrusion for the positioning protrusion to be inserted. When the positioning protrusion is inserted into the positioning port, the stirring head is snapped onto the stirrer body. With the above improvement, when the battery pack rotates a certain angle on the stirrer body, the positioning protrusion in the snap-fit ​​groove will enter the positioning port of the snap-fit ​​protrusion, thereby realizing the quick snap-fit ​​between the battery pack and the stirrer body.

[0011] Preferably, the snap-fit ​​groove includes a vertically arranged insertion section and a rotating section extending along the outer contour of the stirrer body, and the positioning protrusion is disposed in the rotating section. With the above improvement, when the battery pack is snapped into the stirrer body, the snap-fit ​​protrusion is first inserted into the insertion section. When the snap-fit ​​protrusion enters the rotating section, the battery pack is driven to rotate until the positioning protrusion in the snap-fit ​​groove enters the positioning port of the snap-fit ​​protrusion, so as to complete the assembly of the battery pack.

[0012] Preferably, a signal transmission plate is provided on the connecting protrusion, and a signal transmission post is inserted into the battery pack. When the battery pack is snapped onto the stirrer body, the signal transmission post abuts against the signal transmission plate. Through the above improvements, when the battery pack is snapped onto the body, the signal transmission post abuts against the signal transmission plate, thereby realizing signal transmission and improving the daily user experience.

[0013] Preferably, a guide groove is formed on the connecting boss, the signal transmission post is rotated in the guide groove, and the signal transmission piece is placed in the guide groove. Through the above improvements, the signal transmission post can rotate in the guide groove during the installation of the battery pack, thereby improving the stability of the battery pack during the installation process. After the signal transmission post rotates a certain distance, the signal transmission post and the signal transmission piece come into contact, thereby realizing the transmission of signals and realizing the control of the battery pack.

[0014] Preferably, the bottom of the battery pack is provided with a conductive connecting piece, and the connecting protrusion is formed with an insertion groove for inserting the conductive connecting piece. The stirrer body is provided with a clamping conductive piece. The conductive connecting piece is snapped onto the stirrer body as the battery pack rotates and engages with the clamping conductive piece. With the above improvements, when the connecting protrusion is inserted into the connecting groove, the conductive connecting piece engages with the clamping conductive piece as the battery pack rotates, thereby realizing the circuit connection between the battery pack and the stirrer body.

[0015] Preferably, the battery pack is provided with a connecting bracket, and the conductive connecting piece is inserted into the connecting bracket. The connecting bracket is inserted into the insertion slot and rotates with the battery pack. The clamping conductive piece has a conductive abutment groove on the rotating plane for the conductive connecting piece to be inserted. When the battery pack is snapped onto the stirrer body, the conductive connecting piece is inserted into the conductive abutment groove so that the conductive connecting piece and the clamping conductive piece form an electrical connection. Through the above improvements, the stability of the conductive connecting piece installation is improved by using the connecting bracket. When the connecting bracket rotates a certain angle under the action of the battery pack, the conductive connecting piece is inserted into the conductive abutment groove, thereby realizing circuit connection.

[0016] Preferably, the insertion groove is provided with a dustproof sheet, and the dustproof sheet has an insertion port for the conductive connecting piece to pass through. Through the above improvements, external dust is prevented from entering the agitator body.

[0017] Preferably, the battery pack includes a housing, a power supply unit disposed within the housing, a connecting bracket disposed on the housing, and a charging module for charging the power supply unit. The connecting bracket is provided with a signal transmission post for signal transmission and a conductive connecting piece for circuit connection. Through the above improvements, the power supply unit can supply power to the stirrer body, and the charging module can charge the power supply unit. The connecting bracket on the housing, with its signal transmission post and conductive connecting piece for circuit connection, ensures the reliability of the installation of the signal transmission post and the conductive connecting piece.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] By setting a snap-fit ​​protrusion on the battery pack and a snap-fit ​​groove on the mixer body for the snap-fit ​​protrusion to be inserted, and by rotating the snap-fit ​​protrusion along the snap-fit ​​groove at a certain angle, the battery pack is snapped onto the mixer body and an electrical connection is formed. Compared with the traditional method that requires a power cord for power supply, this method not only eliminates the restrictions on the area of ​​use, but also makes the battery pack installation convenient and easy, thus greatly improving the convenience of users.
