A food processor with an angle conversion gear

Abstract

This utility model discloses a food processor with angle-conversion speed control, including a main unit, a circuit board, a motor, a blade, and an angle signal conversion element. The motor is fixedly mounted on the main unit and is connected to the blade drive. The angle signal conversion element is mounted on the main unit and is used to change the output electrical signal according to the tilt angle of the main unit. The angle signal conversion element is electrically connected to the circuit board, and the circuit board is electrically connected to the motor. The circuit board controls the motor speed according to the electrical signal output by the angle signal conversion element. When the food processor is tilted manually, the angle signal conversion element sends an electrical signal to the circuit board based on the detected tilt angle. The circuit board controls the motor speed according to the electrical signal, thereby adjusting the motor speed in real time according to different tilt angles to achieve intelligent mixing processing through different speeds. This avoids problems such as blade jamming at the same speed and eliminates the need to press a speed change button, making it easy to operate.

Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a food processor with angle conversion and speed change. Background Technology

[0002] As people's living standards improve, the demand for convenient and diversified food processing is increasing. Handheld blenders, due to their compact size and flexible operation, are widely used in home kitchens and small restaurants. Currently, the speed control methods for handheld blenders on the market are mainly divided into two categories: constant blending speed and push-button stepless speed control.

[0003] Hand blenders with constant stirring speed can only operate at a single fixed speed, making it difficult to meet the diverse stirring strength and speed requirements of different ingredients (such as hard nuts and soft fruits and vegetables), greatly limiting the product's usage scenarios and processing results. Hand blenders with push-button stepless speed regulation typically use a push-button-triggered sliding rheostat. Specifically, when the user presses the button, the contact of the rheostat slides, changing its output electrical signal. The circuit board receives this signal and controls the motor speed, thus achieving stepless speed regulation. However, this speed regulation method has significant drawbacks: First, the user must constantly press the button and precisely control the depth of the press to adjust the speed, making the operation cumbersome and prone to hand fatigue from prolonged pressing, severely impacting the user experience; second, this speed regulation method relies on button pressing, making it difficult to flexibly adjust the speed in actual use, especially in tilted operations or scenarios requiring two-handed operation (such as blending ingredients in tall containers), and failing to truly adapt to diverse tilting and speed-changing usage scenarios.

[0004] In conclusion, existing speed control technology for handheld mixers can no longer meet users' needs for convenient, efficient, and intelligent food processing. There is an urgent need for a new speed control technology solution to improve the user experience, expand application scenarios, and optimize mixing efficiency. Utility Model Content

This achieves intelligent mixing processing through different speeds, avoiding problems such as blade jamming at the same speed. At the same time, it eliminates the need to press the speed change button, making it convenient to operate. Attached Figure Description

[0032] See Figures 1-5 A food processor with angle-conversion speed control includes a main unit 10, a circuit board 20, a motor 30, a blade 40, and an angle signal conversion element 210. The motor 30 is fixedly mounted on the main unit 10 and is connected to the blade 40 in a transmission manner. The angle signal conversion element 210 is disposed on the main unit 10 and is used to change the output electrical signal according to the tilt angle of the main unit 10. The angle signal conversion element 210 is electrically connected to the circuit board 20, and the circuit board 20 is electrically connected to the motor 30. The circuit board 20 controls the rotational speed of the motor 30 according to the electrical signal output by the angle signal conversion element 210.

[0033] The working principle of this invention is that when the food processor is tilted by the user, the angle signal conversion element sends an electrical signal to the circuit board based on the detected tilt angle. The circuit board controls the speed of the motor based on the preset speed adjustment program and the electrical signal, thereby adjusting the speed of the motor in real time according to different tilt angles. This achieves intelligent mixing by different speeds, avoiding problems such as blade jamming at the same speed. At the same time, it eliminates the need to press the speed change button, making it easy to operate.

[0034] Furthermore, the angle signal conversion element 210 is a gyroscope.

[0035] Furthermore, the angle signal conversion element 210 employs a tilt sensor.

[0036] Furthermore, the angle signal conversion element 210 is an electronic compass.

[0037] See Figure 1 The cutting tool 40 includes a cutting shaft 410 that is connected to the motor 30 for transmission and a cutting head 420 disposed on the cutting shaft 410.

[0038] See Figure 1 The host 10 is connected to a processing cover 50, and a processing cavity 60 is provided at the lower part of the processing cover 50. The cutting head 420 is disposed in the processing cavity 60, and the cutting shaft 410 is rotatably disposed relative to the processing cover 50.

[0039] See Figure 4 The angle signal conversion element 210 is connected to the circuit board 20 by means of wiring, module soldering, etc.

[0040] See Figure 1 and Figure 4 The circuit board 20 is equipped with a first micro switch 220 and a second micro switch 230. The main unit 10 is equipped with a first button 110 and a second button 120. When the first button 110 moves relative to the main unit 10, it can abut against or separate from the sensing end of the first micro switch 220. When the second button 120 moves relative to the main unit 10, it can abut against or separate from the sensing end of the second micro switch 230. The purpose of the first and second micro switches is to match a first speed and a second speed. In normal use, the user can press the first button or the second button to trigger the first micro switch or the second micro switch, thereby controlling the motor to start at the first speed or the second speed to achieve normal mixing. When the food processor tilts, the motor speed is switched based on the electrical signal sent by the angle signal conversion element 210.

[0041] See Figure 5 The circuit board can be set to a preset speed regulation program that the motor speed decreases as the tilt angle gradually increases. This design can improve safety while regulating speed, avoiding safety issues caused by excessive speed when used at an angle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
