Linear motor for small home appliances

A linear motor for small home appliances, comprising a casing and an iron core, wherein the iron core is arranged in the casing, both upper and lower sides of an inner wall of the iron core are each provided with at least one salient pole, and the salient poles on the upper and lower sides are staggered from each other;

• a coil winding is wound on the salient pole, a guide seat is arranged at an inner bottom of the casing, a magnet support is slidably arranged in the casing, the magnet support is provided with a head portion at a position close to an open end of the casing, and a magnet assembly is slidably arranged in the magnet support;
• the magnet assembly is provided with at least one magnet;
• both upper and lower sides of the magnetic support are each provided with at least one window;
• and a position of the window corresponds to that of the salient pole;
• the guide seat is provided with a switching groove, the magnet assembly is provided with a bayonet lock, the bayonet lock is movably embedded in the switching groove so that when the coil winding is electrified and generates a magnetic field same as that of the magnet, the magnet support drives the magnet assembly and the head portion to slide left and right, and at the same time, the magnet assembly slides up and down with respect to the magnet support, to cause the magnet to be embedded in the corresponding window;
• the switching groove comprises a first section, a second section, a third section, and a fourth section connected end to end in sequence;
• a first step is arranged between the first section and the second section, a second step is arranged between the second section and the third section, and a third step is arranged between the third section and the fourth section;
• bottom surfaces of the first section, the second section and the fourth section are all inclined surfaces, a depth of an end of the first section close to the fourth section is greater than a depth of an end of the first section close to the second section, a depth of an end of the second section close to the first section is less than a depth of an end of the second section close to the third section, and a depth of an end of the fourth section close to the third section is less than a depth of an end of the fourth section close to the first section;
• a beveled surface in smooth transition is arranged in the third section;
• the first section and the third section are both straight slots, and the first section and the third section are parallel to each other;
• and the second section and the fourth section are both curved slots;
• and
• the bayonet lock is elastically arranged on the magnet assembly.
