[0018] The beneficial effects of the present invention are:

[0019] 1. This kind of low-noise energy-saving motor and food processor is provided with a gear transmission mechanism. The gear transmission mechanism can not only convert the high-speed rotational motion of the rotor inside the motor into a suitable operating speed by combining gears of different sizes to achieve the adjustment of the rotational speed and torque, but also change the transmission direction of the rotor to meet different application scenarios. There is no need to assemble and connect the gear box in the later use, which is more convenient for the installation and use of the food processor. In addition, an integrated direct drive design is adopted between the gear transmission mechanism and the rotor, which is not only small in size and easy to install, but also can effectively reduce noise.

[0020] 2. This kind of low-noise energy-saving motor and food processor, under normal circumstances, the gear transmission mechanism converts the high-speed rotational motion of the rotor inside the motor into a suitable operating speed for power output. When power output is performed, the gear transmission mechanism first drives the rotating disk on the overload protection mechanism to rotate through the rotating column thereon, and when the rotating disk rotates, the friction resistance between the clamping piece and the friction blocking block provided on the outside drives the transmission kit and the power output shaft to rotate, and finally power is output through the power output shaft. During use, when the stirring mechanism on the food processor is stuck by food due to excessive stirring resistance, the friction resistance between the clamping piece and the friction blocking block is insufficient to drive the transmission kit and the power output shaft to continue rotating. At this time, the clamping piece will swing inward to compress the spring piece. When the spring piece is compressed to a certain extent, the clamping piece will pass over the friction blocking block. At this time, the rotor inside the electric motor will idle, which can perform self-overload protection and avoid damage to the electric motor.

[0021] 3. This low-noise energy-saving motor and food processor can monitor and warn the working status of the overload protection mechanism by setting an electromagnetic early warning mechanism. Under normal circumstances, when the rotating disk rotates, the friction resistance between the clamping piece and the friction blocking block set on the outside drives the transmission kit and the power output shaft to rotate, and finally drives the stirring mechanism to rotate through the power output shaft to output power. In this process, the transmission kit can drive the driven gear A, the linkage shaft and the magnet block on the electromagnetic early warning mechanism to rotate through the linkage gear. When the magnet block rotates rapidly, current will be generated on the coil assembly, and the indicator light will light up normally. At this time, current will also pass through the induction coil, which will generate magnetic force on the iron column. The magnetic force on the iron column can be used to adsorb the iron sheet on the trigger alarm mechanism. At this time, the push-type switch will not control the alarm to turn on. When the stirring mechanism on the food processor is stuck by food and the stirring resistance is greater than When there is friction resistance between the clamping fixture and the friction blocking block on the overload protection mechanism, the friction resistance between the clamping fixture and the friction blocking block cannot drive the transmission kit and the power output shaft to continue rotating. At this time, the transmission kit cannot drive the driven gear A, the linkage shaft and the magnet block on the electromagnetic early warning mechanism to rotate through the linkage gear. After the magnet block stops rotating, no current will continue to be generated on the coil assembly, the indicator light will stop glowing, and at the same time the iron column will also lose its magnetism. At this time, the iron sheet will automatically reset under the action of the reset spring and press the push-type switch to open. The push-type switch will control the alarm to turn on for an alarm reminder. The working status of the overload protection mechanism can be monitored in real time, which is convenient for the staff to discover problems in time and deal with them. Not only can the electric motor be prevented from being damaged by overload, but also the electric motor can be prevented from being seriously heated due to long-term overload operation and wasting electricity, with good energy-saving effect.

[0022] 4. This low-noise energy-saving motor and food processor, when the overload protection mechanism drives the stirring mechanism to stir the food in the cooking pot through the power output shaft, the stirrer on the stirring mechanism will revolve under the drive of the power output shaft. At the same time, the stirrer will rotate on its own under the linkage cooperation of the driven gear B and the ring gear, so that the stirrer can stir the food quickly with high stirring efficiency.

The high-speed rotation of the rotor 3 is converted into a suitable operating speed to achieve the adjustment of the rotation speed and torque, and the transmission direction of the rotor 3 can be changed to meet different application scenarios. There is no need to assemble the connecting gear box in the later use, which is more convenient for the installation and use of the chef machine. The gear transmission mechanism 8 and the rotor 3 adopt an integrated direct drive design, which is not only small in size and easy to install, but also can effectively reduce noise. The bottom end of the gear transmission mechanism 8 is connected to an overload protection mechanism 9, and one side of the overload protection mechanism 9 is meshed and connected with an electromagnetic early warning mechanism 10. A trigger alarm mechanism 11 is provided on one side of the bottom end of the electromagnetic early warning mechanism 10;

Under normal circumstances, the gear transmission mechanism 8 converts the high-speed rotation motion of the rotor 3 inside the motor into a suitable operating speed for power output. When power output is performed, the gear transmission mechanism 8 first drives the overload protection The rotating disk 901 on the protective mechanism 9 rotates, and when the rotating disk 901 rotates, the friction resistance between the clamping piece 907 and the friction blocking block 904 arranged on the outside drives the transmission kit 903 and the power output shaft 902 to rotate, and finally the power is output through the power output shaft 902. During use, when the stirring mechanism 13 on the food processor is stuck by food due to excessive stirring resistance, the friction resistance between the clamping piece 907 and the friction blocking block 904 is not enough to drive the transmission kit 903 and the power output shaft 902 to continue rotating. At this time, the clamping piece 907 will swing inward to compress the spring piece 908. When the spring piece 908 is compressed to a certain extent, the clamping piece 907 will pass over the friction blocking block 904. At this time, the rotor 3 inside the electric motor will idle, which can perform self-overload protection and avoid damage to the electric motor.

[0053] Among them, the motor housing 1 includes an outer shell 101 and heat dissipation fins 102 equidistantly fixed on the surface of the outer shell 101, and fixed legs 103 are symmetrically fixed on both sides of the bottom of the outer shell 101. The heat dissipation fins 102 can improve the heat dissipation effect of the motor housing 1, and the motor can be quickly installed through the fixed legs 103.

[0054] The protective housing 7 includes a housing body 701 fixedly arranged at one end of the motor housing 1 , the inner cavity of the housing body 701 is divided into a first chamber 702 and a second chamber 703 by a partition, and a fixed base 704 is fixedly arranged at the bottom of one end of the housing body 701 .

[0055] Among them, the gear transmission mechanism 8 includes a connecting plate 801 fixedly arranged at the top of the inner cavity of the first chamber 702 and a rotating column 802 rotatably arranged at the top of the inner cavity of the first chamber 702 through a bearing. A transmission rod 803 is rotatably inserted and interspersed on the connecting plate 801 through a bearing. A transmission worm 804 and a transmission gear 805 are fixedly arranged at both ends of the transmission rod 803. A reduction worm wheel 806 is meshed and connected at the bottom of the transmission worm 804, and the reduction worm wheel 806 is fixedly sleeved on the outer side of the rotating column 802. When the rotor 3 drives the power output gear 4 to rotate, the power output gear 4 can drive the transmission rod 803 and the transmission worm 804 to rotate through the transmission gear 805. When the transmission worm 804 rotates, it can drive the reduction worm wheel 806 to rotate. Not only can the high-speed rotational motion of the rotor 3 inside the motor be converted into a suitable operating speed to achieve the adjustment of the rotation speed and torque, but also the transmission direction of the rotor 3 can be changed to meet different application scenarios.

[0056] Among them, the electromagnetic early warning mechanism 10 includes a linkage shaft 1001 that is rotatably inserted through a bearing on a partition between the first chamber 702 and the second chamber 703, and a frame 1002 that is fixedly arranged on the top of the inner cavity of the second chamber 703 through a support rod. A driven gear A1003 is fixedly arranged on the top of the linkage shaft 1001, and a magnet block 1004 is symmetrically fixedly arranged on the outer side of the bottom end of the linkage shaft 1001. Coil assemblies 1005 are symmetrically fixedly arranged on both sides of the inner cavity of the frame 1002. The tops of the two groups of coil assemblies 1005 are electrically connected to wiring ears 1006. An induction coil 1007 is connected in series between the two groups of coil assemblies 1005 through a wire. An iron column 1008 is inserted through the middle of the induction coil 1007, and the iron column 1008 is fixed to the bottom of the inner cavity of the second chamber 703 through a bracket.

[0057] Among them, the wiring ear 1006 electrically connected to the top of the coil assembly 1005 is fixedly arranged on the top of the frame 1002, and an indicator light 1009 is connected in series between the two sets of wiring ears 1006 through a wire. The electromagnetic early warning mechanism 10 can monitor and warn the working state of the overload protection mechanism 9. Under normal circumstances, when the rotating disk 901 rotates, the friction resistance between the outer clamping piece 907 and the friction blocking block 904 can drive the transmission kit 903 and the power output shaft 902 to rotate, and finally the power output shaft 902 can The stirring mechanism 13 is driven to rotate for stirring. During this process, the transmission kit 903 can drive the driven gear A1003, the linkage shaft 1001 and the magnet block 1004 on the electromagnetic early warning mechanism 10 to rotate through the linkage gear 905. When the magnet block 1004 rotates rapidly, current will be generated on the coil assembly 1005, and the indicator light 1009 will light up normally. At this time, current also passes through the induction coil 1007, and magnetic force will be generated on the iron column 1008. The magnetic force on the iron column 1008 can be used to adsorb the trigger alarm mechanism 11.

[0058] Among them, the trigger alarm mechanism 11 includes a U-shaped plate 1101 fixedly arranged on one side of the inner cavity of the second chamber 703, a push-type switch 1102 and an alarm 1106 fixedly installed on one side of the U-shaped plate 1101, a T-shaped pin 1103 is slidably inserted on the U-shaped plate 1101, one end of the T-shaped pin 1103 is fixedly connected to an iron sheet 1104, and a return spring 1105 is sleeved on the outside of the T-shaped pin 1103 between the iron sheet 1104 and the U-shaped plate 1101. When the iron sheet 1104 on the trigger alarm mechanism 11 is adsorbed by the magnetic force on the iron column 1008, the push-type switch 1102 will not control the alarm 1106 to turn on. When the stirring mechanism 13 on the chef machine is stuck by food and the stirring resistance is greater than the friction resistance between the clamping piece 907 and the friction blocking block 904 on the overload protection mechanism 9, the friction resistance between the clamping piece 907 and the friction blocking block 904 will not The transmission kit 903 and the power output shaft 902 can continue to rotate. At this time, the transmission kit 903 cannot drive the driven gear A1003, the linkage shaft 1001 and the magnet block 1004 on the electromagnetic early warning mechanism 10 to rotate through the linkage gear 905. After the magnet block 1004 stops rotating, the coil assembly 1005 will not continue to generate current, the indicator light 1009 will stop emitting light, and at the same time, the iron column 1008 will also lose its magnetism. At this time, the iron sheet 1104 will automatically reset under the action of the reset spring 1105 and press the push switch 1102 to open. The push switch 1102 will control the alarm 1106 to turn on and give an alarm reminder. The working status of the overload protection mechanism 9 can be monitored in real time, which is convenient for the staff to find problems in time and deal with them. It can not only avoid overload damage to the electric motor, but also avoid long-term overload operation of the electric motor and serious heat generation, which wastes electricity and has a good energy-saving effect.

[0059] The push switch 1102 and the alarm 1106 are connected by a wire.

[0060] A food processor, comprising a food processor body 12 and a low-noise energy-saving motor as claimed in any one of claims 1 to 7, wherein the food processor body 12 is provided with a stirring mechanism 13 and a motor mounting cavity 14 connected to the low-noise energy-saving motor, the low-noise energy-saving motor is fixedly mounted in the motor mounting cavity 14 by screws, and a cooking kettle 15 is provided on the food processor body 12 below the motor mounting cavity 14.

[0061] Among them, the indicator light 1009 and the alarm 1106 set on the low-noise energy-saving motor are both fixedly installed on the front surface of the chef machine body 12.

[0062] The stirring mechanism 13 includes a shielding cover 1301, a stirring shaft 1302 rotatably arranged on the shielding cover 1301 through a bearing, and a ring gear 1305 fixedly arranged inside the fixed base 704. The shielding cover 1301 is fixedly connected to the bottom end of the power output shaft 902 arranged on the low-noise energy-saving motor. The stirring shaft 1302 is eccentrically arranged on the shielding cover 1301, and the upper and lower ends of the stirring shaft 1302 are respectively fixedly connected to the driven gear B1303 and the stirrer 1304. The driven gear B1303 is meshedly connected with the ring gear 1305. When the overload protection mechanism 9 drives the stirring mechanism 13 to stir the food in the cooking pot 15 through the power output shaft 902, the stirrer 1304 on the stirring mechanism 13 will revolve under the drive of the power output shaft 902. At the same time, the stirrer 1304 will rotate on its own under the linkage cooperation of the driven gear B1303 and the ring gear 1305, so that the stirrer 1304 can stir the food quickly with high stirring efficiency.

[0063] When working, the rotor 3 can drive the power output gear 4 and the cooling fan 5 to rotate when it rotates. The power output gear 4 can output power, and the cooling fan 5 can quickly dissipate heat for the motor. When the rotor 3 drives the power output gear 4 to rotate, the power output gear 4 can drive the transmission rod 803 and the transmission worm 804 to rotate through the transmission gear 805. When the transmission worm 804 rotates, it can drive the reduction worm gear 806 to rotate, which can not only convert the high-speed rotational motion of the rotor 3 inside the motor into a suitable operating speed to achieve the adjustment of the rotational speed and torque, but also change the transmission direction of the rotor 3 to meet different application scenarios.

[0064] Under normal circumstances, the gear transmission mechanism 8 converts the high-speed rotation of the rotor 3 inside the motor into a suitable operating speed for power output. When the power is output, the gear transmission mechanism 8 first drives the rotating disk 901 on the overload protection mechanism 9 to rotate. When the rotating disk 901 rotates, the friction resistance between the clamping piece 907 and the friction blocking block 904 arranged on the outside drives the transmission kit 903 and the power output shaft 902 to rotate, and finally the power is output through the power output shaft 902. During use, when the stirring mechanism 13 on the chef machine is stuck by food due to excessive stirring resistance, the friction resistance between the clamping piece 907 and the friction blocking block 904 is not enough to drive the transmission kit 903 and the power output shaft 902 to continue rotating. At this time, the clamping piece 907 will swing inward to compress the spring piece 908. When the spring piece 908 is compressed to a certain extent, the clamping piece 907 will pass over the friction blocking block 904. At this time, the rotor 3 inside the electric motor will idle, which can be self-overload protected and prevent the electric motor from being damaged.

[0065] The electromagnetic early warning mechanism 10 can monitor and warn the working state of the overload protection mechanism 9. Under normal circumstances, when the rotating disk 901 rotates, the friction resistance between the outer clamping piece 907 and the friction blocking block 904 can drive the transmission kit 903 and the power output shaft 902 to rotate, and finally the power output shaft 902 can drive the stirring mechanism 13 to rotate for stirring. In this process, the transmission kit 903 can drive the driven gear A1003 on the electromagnetic early warning mechanism 10, the linkage shaft 1001 and the magnet through the linkage gear 905. When the magnet block 1004 rotates quickly, current will be generated on the coil assembly 1005, and the indicator light 1009 will light up normally. At this time, current will also flow through the induction coil 1007, and magnetic force will be generated on the iron column 1008. The magnetic force on the iron column 1008 can be used to adsorb the trigger alarm mechanism 11. When the magnetic force on the iron column 1008 is used to adsorb the iron sheet 1104 on the trigger alarm mechanism 11, the push switch 1102 will not control the alarm 1106 to turn on. When the stirring mechanism 13 on the chef machine is touched by food, the trigger alarm mechanism 1106 will not be turned on. When the object is stuck and the stirring resistance is greater than the friction resistance between the clamping piece 907 and the friction blocking block 904 on the overload protection mechanism 9, the friction resistance between the clamping piece 907 and the friction blocking block 904 cannot drive the transmission kit 903 and the power output shaft 902 to continue to rotate. At this time, the transmission kit 903 cannot drive the driven gear A1003, the linkage shaft 1001 and the magnet block 1004 on the electromagnetic early warning mechanism 10 to rotate through the linkage gear 905. After the magnet block 1004 stops rotating, no current will continue to be generated on the coil assembly 1005, indicating that The indicator light 1009 will stop emitting light, and at the same time, the iron column 1008 will also lose its magnetism. At this time, the iron sheet 1104 will automatically reset under the action of the reset spring 1105 and press the push switch 1102 to open. The push switch 1102 will control the alarm 1106 to turn on the alarm reminder. The working status of the overload protection mechanism 9 can be monitored in real time, which is convenient for the staff to discover problems in time and deal with them. It can not only avoid overload damage to the electric motor, but also avoid long-term overload operation of the electric motor and serious heat generation, which wastes electricity and has a good energy-saving effect.
