Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a knife-stopping protection structure for a handheld mixer. Background Technique

[0002] A cooking mixer integrates functions such as making soy milk, grinding dry powder, squeezing juice, making minced meat, and shaving ice, and is a household appliance used to make various foods such as juice, soy milk, jam, dry powder, shaved ice, and minced meat. It is a product after the juicer becomes more diversified. Compared with a general mixer, a handheld mixer is smaller in volume and can be inserted into a container for stirring, making it more convenient to use.

[0003] Since the handheld mixer needs to separate the body from the stirring container when completing the stirring operation, during this process, the stirring shaft is separated from the driving shaft. Since the stirring shaft still has rotational power and cannot stop in a short time, it is easy to cause the stirring shaft with stirring blades to fly out of the stirring container and injure people, posing a great safety hazard. Content of the Utility Model

The shaft member is connected to the transmission structure. The shaft member is composed of a stirring shaft with a hollow cavity and several blades arranged around the stirring shaft. The bottom of the stirring container is provided with a positioning shaft for connecting the stirring shaft. The stirring shaft is sleeved on the positioning shaft. The stirring shaft rotates along the axis of the positioning shaft through the transmission structure, and a knife-stopping structure is arranged at the connection between the stirring shaft and the positioning shaft to make the stirring shaft stop rotating within 1.5 seconds.

[0007] The knife-stopping structure includes a first chamber and a second chamber formed in the stirring shaft. A convex block is arranged on the positioning shaft, and the convex block is correspondingly arranged on one side of the first chamber. The second chamber is arranged above the first chamber, and a detachable weight member is arranged in the second chamber. The second chamber is arranged on the side of the stirring shaft, and the first chamber is opened at the axis of the stirring shaft. There is also an activity gap between the stirring shaft and the positioning shaft. When the stirring shaft is stationary on the positioning shaft, the stirring shaft leans against the positioning shaft in an inclined manner under the action of the gravity of the weight member.

[0008] As a further description of the above technical solution, the mixing body is cylindrical, and the mixing body is provided with a high-speed gear and a low-speed gear. A drive module is built into the mixing body, and the drive module is connected to a transmission structure. The transmission structure drives the mixing shaft to rotate. The transmission structure includes a mounting seat and a reduction gear set. The mounting seat passes through the end cover, and the end cover is connected to the mixing container by means of a buckle.

[0009] As a further description of the above technical solution, a convex portion is provided on the outer edge of the end cover, and a clamping portion is provided on the inner edge of the port of the mixing container. The convex portion includes a plurality of L-shaped convex strips, and the convex strips are integrally formed with the end cover. The clamping portion includes a card slot corresponding to the installation of the convex strip one by one, and the end cover is screwed onto the mixing container in a clockwise direction.
