Description

Technical Field

[0001] This utility model relates to a mixer. Background Technology

[0002] Existing food processing machines, such as mixers, include a main unit and a mixing cup assembly. The mixing cup assembly contains mixing blades, and the main unit houses a motor. The mixing cup assembly sits on the main unit, and the mixing blades and the motor are connected by a shaft transmission mechanism. This causes the output shafts of the mixing blades and the motor to easily become eccentric, limiting the rotational speed of the mixing blades driven by the motor. Utility Model Content

[0003] The purpose of this invention is to provide an improved mixer that prevents the mixing blades and the motor output shaft from becoming misaligned.

[0004] The purpose of this utility model is achieved as follows.

[0005] An improved mixer includes a mixing cup assembly, which includes a cup body, mixing blades, and a motor. A heating plate is provided at the bottom of the cup body, and a column extends downward from the bottom of the heating plate. The motor is connected and fixed to the column through a shock-absorbing device. The motor is located below the heating plate, and the output shaft of the motor passes through the heating plate to drive the mixing blades to rotate inside the cup body.

[0006] In this invention, the motor is suspended below the heating plate, and the output shaft of the heating plate and the motor are coaxial to avoid eccentricity. The motor's output shaft can drive the stirring blades to rotate at high speed. A vibration damping device isolates motor noise from transmission through the column and heating plate, reducing the operating noise of the mixer. The vibration damping device also prevents heat from the heating plate from being transferred to the motor.

[0007] Furthermore, the shock absorption device is a shock absorption and heat insulation sleeve, which is placed at the bottom of the column. The outer circumference of the shock absorption and heat insulation sleeve is provided with an annular groove, and the outer circumference of the motor housing is provided with a fixing ring, which is placed in the annular groove.

[0008] The shock absorption device has a simple structure, is easy to assemble, and is convenient to install with the fixing ring.

[0009] Furthermore, the bottom surface of the column is provided with screw holes. The column includes an upper section and a lower section, and a step portion with the stepped surface facing downwards is formed between the upper and lower sections. The shock-absorbing and heat-insulating sleeve is fitted onto the lower section. The bolts and screw holes are threadedly connected, and the shock-absorbing and heat-insulating sleeve is clamped between the bolt nut and the step portion.

[0010] The assembly of the shock-absorbing and heat-insulating sleeve and the column is simple and easy.

[0011] Furthermore, four columns extend downward from the bottom of the heating plate, and the four columns are arranged in a ring at equal intervals around the center of the heating plate. Four fixing rings are provided radially around the outer periphery of the motor housing, and are arranged in a ring at equal intervals around the center of the motor's output shaft. The output shaft of the motor and the center of the heating plate are coaxial.

[0012] The motor and heating plate are securely and stably fixed.

[0013] Furthermore, the heating plate has a through hole in the center, and the top of the motor housing extends upward to form a fixed seat. The fixed seat has a shaft hole, and the top of the fixed seat has a fixed groove that is coaxially connected to the shaft hole. A sealing device is provided in the fixed groove. The top of the motor's output shaft passes through the shaft hole, the fixed groove, the sealing device, and the through hole before extending into the cup body. After the motor and the column are connected and fixed, the top surface of the sealing device abuts against the periphery of the through hole.

[0014] The sealing device seals the through hole to prevent water leakage from the cup.

[0015] Furthermore, the heating plate has a downward-facing groove formed by an upward convexity at its center, and the groove has a through hole at its center. The fixing seat is shaped like a truncated cone. After the motor and the column are connected and fixed, the fixing seat is inserted into the groove, and a sealing device is clamped between the groove and the fixing seat.

[0016] The settling tank and fixed seat are positioned and assembled to facilitate clamping the sealing device.

[0017] Furthermore, the sealing device includes a sealing ring and a waterproof oil seal. The waterproof oil seal is placed in a fixed groove, and its inner circumferential surface rolls into contact with the output shaft for axial sealing. The bottom surface of the sealing ring is fitted onto the top of the fixed seat, and the top surface of the waterproof oil seal abuts against the sealing ring. The sealing ring is clamped between the groove and the fixed seat for radial sealing. The sealing effect is good.

[0018] In this invention, the motor is suspended below the heating plate, and the output shaft of the heating plate and the motor are coaxial to avoid eccentricity. The motor's output shaft can drive the stirring blades to rotate at high speed. A vibration damping device isolates motor noise from transmission through the column and heating plate, reducing the operating noise of the mixer. The vibration damping device also prevents heat from the heating plate from being transferred to the motor. The assembly structure between the heating plate, vibration damping device, and motor is simple and easy to implement. Attached Figure Description
