Detailed Description

Various embodiments of the present disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustrative purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the disclosure.

In this specification, "coupled" may include both direct and indirect connections, where "drive shaft coupled to drive" means that rotation of the drive can result in rotation of the drive shaft. "decoupling" may include decoupling from a direct connection or decoupling from an indirect connection, wherein "drive shaft decoupled from the drive" means that rotation of the drive cannot result in rotation of the drive shaft.

In the following description, like reference numerals denote like components. The terms "first" and "second" used in the present specification are used only for indicating different components and do not limit the components in any way.

Fig. 1 shows an external view of an exemplary meat mincing device 100.

The meat mincing device 100 shown in fig. 1 comprises a main body 1, a minced meat attachment 2 connected to the main body 1, and a feed cylinder 3. Wherein the main body 1 includes a driver (not shown) therein, the meat mincing accessory 2 includes a meat mincing chamber 60, the meat mincing chamber 60 accommodates therein a blade and a drive shaft (not shown) for rotating the cutter head, and the head 10 is positioned at an outlet end of the meat mincing accessory for holding the blade and the drive shaft in the meat mincing chamber. During the operation of the meat grinder, when the cutter head 10 is removed, the blades are exposed, and if the transmission shaft is still rotating, the cutter head driven to rotate by the transmission shaft may cut a user, causing a safety accident.

The present disclosure provides a meat mincing device that provides two magnets that repel each other in a drive mechanism that couples a drive shaft to a driver, where a first magnet is coupled to the drive shaft and a second magnet is coupled to the driver. The equipment can make the transmission shaft and the driver be disconnected through the repulsion force between the magnets when the handpiece is taken down/opened, so that the blade stops rotating, and the safety of a user is ensured.

Fig. 2 shows an exploded schematic view of the meat mincing device 100. Fig. 3 shows an exploded schematic view of the transmission 270. Fig. 4 shows a schematic partial cross-sectional view of the meat mincing device 100.

As shown in fig. 2 to 4, the meat mincing device 200 includes a head 10, a knife plate 20, a blade 30, a positioning frame 35, a drive shaft 40, a worm-shaped blade 50, a minced meat chamber 60, a drive mechanism 70, and a driver 90.

Wherein the drive shaft 40, the worm-like blade 50, the drive mechanism 70 and the blade 30 are accommodated in the meat-mincing chamber 60. The drive shaft 40 is coupled to the driver 90 via a drive mechanism 70, and the blade 30 is connected to the drive shaft 40, for example, disposed at an end of the drive shaft 40 near the handpiece 10, so as to be rotatable by the drive shaft 40. The worm-like blade 50 extends around the drive shaft 40 for conveying the raw meat from the inlet of the meat mincing chamber 60 to the blade 50 for mincing, while it may also perform a partial mincing function itself.

The head 10 is detachably connected to the outlet of the meat mincing chamber 60, for example, the head 10 is a nut screwed on the outlet end of the meat mincing chamber 60. A knife plate 20 is arranged between the handpiece 10 and the blade 30, the blade 30 being arranged to rotate between the fixed knife plate 20 and the fixed positioning frame 35. The spacer 35 includes a plurality of channels for controlling the amount of feed of meat delivered by the worm blade 50 to the region of the blade 30 for smooth feeding and thus relatively uniform particle size of the cut meat. The cutter plate 20 includes a plurality of through-holes, and the meat cut by the blades 30 is output from the meat mincing machine 100 through the through-holes of the cutter plate 20.

As shown in fig. 3 and 4, the transmission 70 further includes a shaft clutch 72 and a drive clutch 74, the shaft clutch 72 being coupled to the drive shaft 40, and the drive clutch 74 being coupled to the driver 90. One of the shaft clutch 72 and the drive clutch 74 includes a male portion and the other includes a female portion, the male portion extending into the female portion when the two are engaged. For example, both shaft clutch 72 and drive clutch 74 include a plurality of teeth such that when shaft clutch 72 and drive clutch 74 are engaged, the plurality of teeth of shaft clutch 72 interlock with the plurality of teeth of drive clutch 74 such that power output from driver 90 may drive the rotation of drive shaft 40.

The transmission mechanism 70 further comprises two magnets 82 and 84, wherein the first magnet 82 has a first through hole 83, and a first screw 86 extends through the first through hole 83 to attach to the axle clutch 72 to connect to the transmission shaft 40; the second magnet 84 has a second through hole 85, and a second screw 88 extends through the second through hole 85 to attach to the drive clutch 74 to connect to the driver 90. The magnets 82 and 84 have a mutually repulsive force between them, e.g., like poles of the magnets 82 and 84 are opposite. This repulsive force urges shaft clutch 72 and drive clutch 74 away from each other.

When the meat mincing device 100 is in use, when the head 10 is positioned in a holding position, such as screwed into the outlet end of the minced meat chamber 60, it holds the drive shaft 40 in the minced meat chamber 60 and urges the drive shaft 40 to move in a direction closer to the drive clutch 40 so that the shaft clutch 72 connected to the drive shaft 40 engages the drive clutch 74 by interlocking of the plurality of teeth. At this point, the two mutually repelling magnets 82 and 84 urge drive shaft 40 away from drive clutch 74, pressing it against handpiece 10 or a component held in place by handpiece 10, such as blade 20.

If the head 10 is moved away from the holding position during use, for example, is unscrewed from the outlet end of the ground meat chamber 60, the shaft clutch 72 will be moved in the direction of the outlet of the ground meat chamber 60 along the axis of the drive shaft 40 by the repulsive force between the magnets 82 and 84, so that the teeth of the shaft clutch 72 are disengaged from the teeth of the drive clutch 72, and the drive shaft 40 is thus decoupled from the driver 90 to stop rotating. With this design, it is possible to prevent injury to the user when the head 10 is removed and the blade 30 or the worm-shaped blade 50 is exposed to the outlet of the meat mincing chamber 60.

In one embodiment, the drive 90 is a motor. A gearing arrangement may also be included between the driver 90 and the transmission 70, with the drive clutch 74 being connected to an output shaft of the gearing arrangement.

In one embodiment, the transmission mechanism 70 may include more than two magnets, for example, two or more sets of magnets that repel each other.

In one embodiment, the first and second screws are limit screws. In other embodiments, the magnet may also be attached to the axle/drive clutch by other attachment means or means.

In one embodiment, the blade 30 may include one or more blades.

In one embodiment, the worm-like blade 50 may also be a helical structure for conveying raw meat through the meat mincing chamber.

In one embodiment, the cutting plate 20 is replaceable, and cutting plates having different through hole sizes may be selected as desired; in other embodiments, the knife plate 20 may be integrated into the head 10 or formed as part of the head 10, or the meat mincing device may not include the spacer 35.

In one embodiment, the head 10 can be positioned in a holding position at the outlet of the ground meat chamber using a screw-on, detent design, or the like, which can be removed entirely to move from the holding position; in other embodiments, the head may be pivotally connected to the meat mincing chamber outlet by a snap fit or the like, and need not be removed entirely when removed from the holding position.

In one embodiment, the meat mincing chamber 60 is fixedly connected to the main body 1, and the components thereof, at least the blade 30 and the worm-like blade 50, can be removed from the meat mincing chamber 60.

In one embodiment, the meat mincing device 100 can comprise two parts, a main body including the motor/driver 90, the drive clutch 74 and the second magnet 84, and an accessory including the minced meat chamber 60, the knife plate 20 housed in the minced meat chamber 60, the blades 30, the drive shaft 40, the worm-shaped blades 50, the minced meat chamber 60 and the drive mechanism 70, and the head 10 screwed to the outlet of the minced meat chamber 60. The accessory is removably attached to the base as a unit.

In the present disclosure, magnets are used to decouple the drive shaft from the driver, rather than springs to generate the urging force. The design of using the repulsive force between the magnets to disengage the engaged shaft clutch from the drive clutch provides greater safety than using a spring. This is because the repulsive force between the magnets does not change with the use time, and the spring is fatigued or aged with the use time. Once the spring's resilience is reduced, its spring force may be insufficient to disengage the drive shaft from the driver, and it may be difficult for the user to anticipate when this will occur, thereby creating a potential hazard.

Furthermore, the spring force is a contact force, and if a spring is used, the spring must be in physical contact with the drive shaft and the drive mechanism, which may create friction with the spring, which may impede the rotation of the drive shaft. And the repulsion between the magnets is non-contact force, when the shaft clutch is jointed with the driving clutch, the two magnets can not be contacted, thereby avoiding generating friction force for obstructing the motion of the transmission shaft and ensuring smooth operation.

Furthermore, the two magnets in the present disclosure are fixed to the transmission shaft and the driver by screws, respectively, and the positions thereof are more easily aligned, thereby making the installation more convenient and accurate.

Although the meat mincing device is described in this disclosure as an example of the above-described structural design, it will be appreciated that similar structural designs may be applied to other kitchen utensils. For example, the above-described design can be used as an accessory or component of a kitchen appliance having a motor, such as a food blender, juicer, dough mixer, chef machine, food processor, etc.

The above embodiments are described herein by way of example only. Many variations are possible without departing from the scope of the disclosure as defined in the claims. While various examples and other information are used to explain various aspects within the scope of the appended claims, the particular features or arrangements of such examples should not be taken as limiting the claims, as those skilled in the art will be able to use the claimed examples to derive various implementations.

Furthermore, although some subject matter may have been described in language specific to structural features and/or methodological steps, it is to be understood that the subject matter defined in the claims is not necessarily limited to the described features or acts. For example, such functionality may be distributed differently or performed in components other than those identified herein. The described features and steps are disclosed as examples only of components of systems and methods within the scope of the appended claims.
