[0002] A blender is an essential kitchen appliance in modern families. According to different application scenarios, blenders are divided into various product types, such as blenders, wall breakers, soy milk makers, baby food makers, etc.
[0003] A blender generally consists of a base and a cup body. The blender drives the cutter in the cup body to rotate through the motor in the base to achieve the stirring function. To facilitate the taking and placing of food in the blender, the cup cover can generally be opened or closed by rotating a certain small angle, making the process of opening or closing the cup cover simple and fast.
[0004] The CE safety standards (EMC directive and LVD directive) require that household appliances (such as food processors, coffee makers, etc.) have a cup cover interlock safety mode. When the cup cover is not correctly placed or locked in position, the device will not start or operate to prevent injuries or equipment damage caused by improper operation. Therefore, necessary improvements need to be made to the blender according to the CE safety standards.
[0005] Patent No. 201680022331.2, "Interlocking Stirring System" of Vitamix Management Co., Ltd., USA, discloses a technical solution of "an interlocking stirring system, including: a base, including a motor, a first set of induction coils and one or more sensors; and a container, including a second set of induction coils and two or more switches. When the second set of induction coils is operably positioned on top of the first set of induction coils, the second set of induction coils is selectively inductively coupled with the first set of induction coils, and the two or more switches are spaced apart around the boundary of the container; a cover, capable of being operably attached to the container, and including one or more coils provided in the main body of the cover; wherein, the state of the container and / or the cover is determined based on changes in the electrical properties of the first set of induction coils and / or the second set of induction coils monitored by the one or more sensors. When the container is operably positioned on top of the base and the two or more switches operably detect the cover attached to the container, the base selectively allows the operation of the motor" to solve the technical problem of "when the cup cover is not correctly placed or locked in position, the device will not start or operate".
