[0002] A food blender can conveniently blend, crush or mix various food materials. The motor drives the blending shaft to rotate. A blending blade is installed on the blending shaft. The blending blade rotates at high speed to crush the food in the blending cup. As is known to all, during the blending process of the blender, a large amount of heat will be generated due to the friction between the food, between the food and the blending blade, and between the food and the cup. This heat will also be dissipated to the food in the blending cup, making it hotter and thus affecting the taste of the food.

[0003] The blades inside the existing food mixer are usually fixed on the middle rotating shaft. When the blades at the local position are damaged, it is necessary to remove the three sets of blades on a fixed ring for replacement, which is rather cumbersome. In addition, only one side of the existing blade is the cutting surface, and the cutting efficiency is low. Therefore, a variable speed direct drive multifunctional food mixer is designed to solve the above problems. Utility Model Content

[0021] Furthermore, a sealing cover 104 is sleeved on the upper end of the mixing box 103. The sealing cover 104 is made of rubber and can ensure the sealing performance of the sealing cover 104 when it is in contact. A handle 105 is also fixedly connected to the outside of the mixing box 103 for easy picking. The lower end of the handle 105 is fixedly connected to one side of the connecting plate 102. An insert block 113 is fixedly connected to one side of the mixing box 103. The lower end of the insert block 113 is inserted into the upper end of the handle 105 to fix the position of the sealing cover 104 and achieve a sealing effect.

[0022] Furthermore, a display screen 106 is fixedly connected to one side of the base 101, a speed knob 107 is provided below the display screen 106, and three control buttons 108 are provided above the display screen 106. The base 101 body is made of a stainless steel shell, and the display screen 106, the speed knob 107 and the control buttons 108 are electrically connected to the internal motor 201. The motor 201 adopts a high-torque direct-drive brushless motor to reduce the noise and cost caused by the complex mechanical structure design. The motor 201 is driven by a low-speed square wave starter. According to the actual output speed requirements, as the output speed increases, it automatically switches to a hybrid drive mode of FOC drive control. The motor 201 achieves a high power output of more than 1100W within the speed range of 300 to 20000rpm. It can meet different speed and load requirements and increase the flexibility of use.

The limiting member 212 and the outer side of the plug 211 are both inserted into the through hole 207, which is convenient for fixing the position of the blade 208 and is more convenient for installation and disassembly. When a blade 208 is damaged, the corresponding limiting member 212 can be directly pulled out from the plug 211 to replace the blade 208, saving time and effort.

[0026] The working principle of the utility model is as follows: when in use, the staff puts the food into the mixing box 103, covers the sealing cover 104, and inserts the plug block 113 at one end into the handle 105 to keep it fixed, so that the upper end of the rotating rod 203 is inserted into the middle position of the lower end of the sealing cover 104, and the control button 108 is pressed to control the operation of the motor 201, and the blade 208 on the outside of the fixing ring 205 is used to cut and crush the food. When a blade 208 is partially damaged, it is only necessary to move the limit piece 212 out of the plug 211 to move the blade 208 out of the plug slot 206, and replace the blade 208. The motor 201 is an ultra-wide-range variable-speed direct-drive power transmission device, which can automatically adjust the speed according to different load requirements.
