Description

Technical Field

[0001] This invention relates to the field of juicer technology, and in particular to a motor fixing structure for a juicer. Background Technology

[0002] The existing juicer includes a cup body, a blade, a motor base, a motor, and a top cover. The upper part of the cup body is provided with a motor base, and the bottom of the motor base has a shaft hole. The motor is placed on the motor base, and the motor shaft passes through the shaft hole and extends into the cup body. The blade is provided on the motor shaft inside the cup body. The top cover is placed on the upper part of the cup body and presses down on the motor base. The juicer with the above structure has the following shortcomings: (1) The motor is only fixed by the motor base, which is not strong enough. When the motor rotates at high speed, it is easy to cause a lot of noise due to vibration. In addition, due to the lack of strength, the motor is easy to affect the cutting and turbulence effect of the blade due to displacement. Summary of the Invention

[0003] The purpose of this invention is to provide a motor fixing structure for a juicer that offers good motor stability, low noise, and effective blade mixing.

[0004] The objective of this invention is achieved as follows:

[0005] A motor fixing structure for a juicer includes a cup body, a blade, a motor base, a motor, and a top cover. The motor base is located on the upper part of the cup body, and a shaft hole is opened at the bottom of the motor base. The motor is placed on the motor base, and the motor shaft passes through the shaft hole and extends into the cup body. The blade is installed on the motor shaft inside the cup body. The structure is characterized by further including a circuit board and a motor positioning bracket. The circuit board is placed on the motor positioning bracket and together with it on the motor base. The motor positioning bracket has a positioning groove, and the upper part of the motor is embedded in the positioning groove. The top cover is placed over the upper opening of the motor base and presses down on the circuit board. This motor fixing structure for a juicer, by adding a motor positioning bracket, fixes the circuit board to the motor base. The positioning groove on the motor positioning bracket fits over the upper part of the motor, and the top cover presses down on the circuit board, so that the circuit board, motor positioning bracket, and motor are firmly fixed to the motor base. Therefore, the motor operates with low noise and good turbulence and stirring effect.

[0006] The present invention can also employ the following further technical solutions:

[0007] Furthermore, the upper part of the motor positioning frame extends upward to form a connecting post with a hole. Corresponding to the connecting post positions, through holes are respectively opened on the circuit board and the upper cover. Screws are inserted through the through holes in the upper cover, pass through the through holes in the circuit board, and are fixed in place by the holes in the connecting post, thus securing the upper cover, circuit board, and motor positioning frame together. This structural method ensures a firm connection between the motor positioning frame, circuit board, and upper cover, and facilitates assembly and disassembly.

[0008] Furthermore, the perforated connecting post abuts against the bottom wall of the circuit board to prevent the circuit board from easily shifting.

[0009] Furthermore, a positioning boss is provided on the top of the motor, and the positioning boss on the top of the motor is embedded in the positioning groove; this cooperation between the positioning boss and the positioning groove makes the motor more secure.

[0010] Furthermore, a support column extends upward from the upper part of the motor positioning frame, and a positioning hole is opened on the circuit board corresponding to the position of the support column. The upper part of the support column is inserted into the corresponding positioning hole. Inserting the upper part of the support column into the corresponding positioning hole can further improve the firmness of the circuit board.

[0011] Furthermore, the positioning groove of the motor positioning frame is a circular groove, and the positioning boss on the top of the motor is a circular boss; the combination of this circular groove and the circular boss provides a better firmness.

[0012] Furthermore, a large circular sleeve is provided at the bottom of one end of the motor positioning frame, and the positioning groove is provided at the top center of the large circular sleeve. The large circular sleeve is fitted onto the upper part of the motor, and the positioning boss on the top of the motor is embedded in the positioning groove. This fitting of the large circular sleeve onto the upper part of the motor limits the top of the motor and its positioning boss, which is more conducive to further improving the stability of the motor.

[0013] Furthermore, electrode clearance openings are provided on both sides of the large circular sleeve, and motor electrodes are provided on both sides of the positioning boss on the top of the motor. The two motor electrodes pass through the electrode clearance openings on both sides of the large circular sleeve, so that the two motor electrodes pass through the electrode clearance openings on both sides of the large circular sleeve, thereby achieving electrical connection.

[0014] Furthermore, it also includes a battery, which is pressed onto the motor base by the top cover, and the battery is electrically connected to the circuit board and the motor; in this way, the juicer is powered and convenient to use, and the battery is firmly fixed between the top cover and the motor base.

[0015] Furthermore, it also includes a battery, and the motor positioning frame is also provided with a battery clamp, in which the battery is clamped; the battery is secured by the motor positioning frame, making it easy to install and remove.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) The motor fixing structure of this juicer is achieved by adding a motor positioning bracket, which is used to fix the motor positioning bracket to the circuit board. The positioning slot on the motor positioning bracket covers the upper part of the motor, and the circuit board is pressed down by the upper cover, so that the circuit board, the motor positioning bracket and the motor are firmly fixed to the motor base. Therefore, the motor has low noise and good turbulence and stirring effect when it is working.

[0018] (2) Furthermore, the upper part of the machine positioning frame extends upward to form a connecting post with holes. The circuit board and the top cover have through holes corresponding to the positions of the connecting posts. Screws are inserted through the through holes of the top cover, pass through the through holes on the circuit board and the holes of the connecting posts to fix them together, so that the top cover, the circuit board and the motor positioning frame are fixed together. This structure makes the motor positioning frame, the circuit board and the top cover firmly connected together and easy to assemble and disassemble. Moreover, the top of the connecting post with holes abuts against the bottom wall of the circuit board to prevent the circuit board from easily shifting.

[0019] (3) Additionally, a positioning boss is provided on the top of the motor, and the positioning boss on the top of the motor is embedded in the positioning groove; the cooperation between the positioning boss and the positioning groove makes the motor more secure. Attached Figure Description
