Background

A sewing machine is a machine that interweaves or sews one or more layers of stitching material by forming one or more stitches on the stitching material with one or more stitching threads. The sewing machine can sew cotton, hemp, silk, wool, artificial fiber and other fabrics, leather, plastic, paper and other products, and the sewn stitch is neat, beautiful, flat, firm, fast in sewing speed and simple and convenient to use. The sewing machine has played a very great role in our daily lives. The foot pedal of the existing sewing machine is used for controlling the sewing, and the thread cutting and the presser foot lifting after the sewing are required to be completed by operators or controlled by other controllers.

Hall elements are semiconductors that employ the hall effect. The method is generally used for measuring the rotating speed of a rotor in a motor, such as a magnetic drum of a video recorder, a cooling fan in a computer and the like; is a magnetic sensor based on Hall effect, has been developed into a variety of magnetic sensor product families, and has been widely used. The hall element is a magnetic sensor based on the hall effect. The magnetic field and the change thereof can be detected by using the magnetic field sensor, and the magnetic field sensor can be used in various occasions related to the magnetic field. Hall elements have many advantages, such as firm structure, small volume, light weight, long service life, convenient installation, low power consumption, high frequency (up to 1 MHZ), shock resistance, and resistance to pollution or corrosion by dust, greasy dirt, water vapor, salt fog, etc.

The three-gear pedal device of the novel sewing machine comprises a pedal plate and a base, wherein the middle part of the pedal plate is provided with a rotating shaft, the pedal plate is arranged on the base through the rotating shaft and can rotate around the rotating shaft, an induction module is arranged on the base and comprises a Hall element and a photoelectric switch, and a magnet for triggering the Hall element and a reflecting sheet for triggering the photoelectric switch are arranged on the pedal plate; the sensing module is connected with a control circuit. The three-gear pedal device of the novel sewing machine adopts the Hall element and the photoelectric switch as trigger elements, and the output voltage of the Hall element is in direct proportion to the linear change of the magnetic field strength under the condition of certain working voltage, so that the Hall element is used for controlling the sewing process of the sewing machine; the two photosensitive sheets of the photoelectric switch are used for controlling the sewing machine to cut threads and lift the presser foot. The pedal device adopts a Hall element and a photoelectric switch as a trigger element, has the advantages of adopting a linear Hall as a sensing element, having good linearity, simultaneously having no problems such as light attenuation, environment brightness correlation and the like (only related to magnetic field intensity), adopting the photoelectric switch as the sensing element, having the problems of light attenuation (the brightness of the light emitting element can be weakened along with the elongation of the brightness under the condition of long-time power on of the light emitting element), and having the influence of the environment brightness on the photosensitive receiving part.
