- the worm like blade 50 may also be a helical structure for feeding raw meat through the meat mincing chamber.
- the blade plate 20 may be replaced, and blade plates having through-holes of different sizes may be selected according to needs.
- the blade plate 20 may be integrated in the mincer head 10 or be part of the mincer head 10, and the meat mincing apparatus may not comprise the positioning bracket 35.
- the mincer head 10 may be positioned at the outlet of the meat mincing chamber in the retaining position by means of thread screwing, snap- fitting design, etc., and may be completely removed and then moved away from the retaining position.
- the mincer head may also be connected to the outlet of the meat mincing chamber by means of pivot snap-fitting, etc., and when being moved away from the retaining position, the mincer head does not need to be completely removed.
- the meat mincing chamber 60 is fixedly connected to the main body 1, and among members accommodated therein, at least the blade 30 and the worm like blade 50 can be removed from the meat mincing chamber 60.
- the meat mincing apparatus 100 may comprise two parts: a main body and an accessory.
- the main body comprises a motor/drive 90, a drive clutch 74, and a second magnet 84.
- the accessory comprises: a meat mincing chamber 60; a blade plate 20, a blade 30, a transmission shaft 40, a worm like blade 50 and a transmission mechanism 70, which are accommodated in the meat mincing chamber 60; and the mincer head 10 that screws onto the outlet of the meat mincing chamber 60.
- the accessory is removably attached to a base as a whole.
- the magnets are used instead of a spring to produce an urging force to decouple the transmission shaft from the drive.
- the design of using the repulsive force between the magnets to disconnect the shaft clutch from the drive clutch has higher safety. This is because the repulsive force between the magnets may not change over time, whereas the spring may be fatigue or aging over time. Once the elasticity of the spring is reduced, an elastic force of the spring may be insufficient to disconnect the transmission shaft from the drive, and it is difficult for the user to predict when this situation will occur, thereby resulting in a potential danger.
- the spring force is a contact force
- the spring is required to be in physical contact with the transmission shaft and the drive mechanism that may generate a friction force between same and the spring, which may hinder the rotation of the transmission shaft.
- the repulsive force between the magnets is a non-contact force, the two magnets may not be in contact when the shaft clutch and the drive clutch are engaged, so as to prevent generating the friction force that hinders motion of the transmission shaft and thus achieve smooth operation.
- the two magnets in the present disclosure are respectively fastened on the transmission shaft and the drive through the screws, and then are easy to be aligned in position, thereby making the installation more convenient and accurate.
- the meat mincing apparatus in the present disclosure is used as the embodiment of the above structural design, it can be understood that the similar structural design may also be applied to other kitchen appliances.
- the above structural design may be an accessory or a component of a kitchen appliance having a motor, such as a food mixer, a juicer, a dough maker, a stand mixer and a food processor.
