Technical Field
[0001] The invention relates to the technical field of household appliances, in particular to a household blender with a protective structure and a use method thereof. Background Art
[0002] As people's living standards improve, the demand for diversified kitchen appliances is also growing. As a common kitchen appliance, the blender has multiple functions such as stirring, crushing and mixing, and is widely used in food processing and cooking. Household blenders are mainly divided into handheld blenders, table blenders, cutting blenders and special function blenders. The cutting blender is also called a food processor or a multi-function blender, which combines the functions of stirring and cutting. Its main advantages are good cutting effect, fast speed and simple operation. It is currently the mainstream blender in households. However, the start switch of the existing blender linked to the micro switch generally adopts a button type, and whether the micro switch in most blenders is connected is completely determined by the installation status of the blender cup, so that after long-term use, all connected circuits in the blender will easily short-circuit or even leak, causing safety hazards.
[0003] The announcement number is: CN110123164B, which discloses a blender, which is combined with a first switch structure and a second switch structure, and the micro switch can only be triggered when the two switch structures act together. Even if the blender is plugged in during use, there is no need to worry about water entering to cause leakage or short circuit, which reduces safety hazards. However, when the blender is in use, there is no component for fixing the first switch structure, so that when blending food, the user needs to always press the first switch structure, so that the user cannot perform other work while blending food, which has great limitations in actual use.
[0004] Meanwhile, in daily life, blenders are used to crush and mix some relatively hard and tough foods, but most existing household blenders are provided with two or four blades. When mixing some large and tough foods, the food easily blocks the blades, so that when starting, the blades will start slowly or fail to start due to the obstruction of the food. If not handled in time, the internal components of the blender will be damaged, making the blender unusable.
[0005] Based on this, a household blender with a protective structure and a method of use are now provided, which can eliminate the disadvantages of existing devices. Summary of the invention
