Specific embodiment
Further to illustrate that the application is the technical means and efficacy reaching predetermined purpose and being taken, below in conjunction with attached drawing
And preferred embodiment, to specific embodiment, structure, feature and its effect according to the application, detailed description is as follows.Following
In explanation, what different " embodiment " or " embodiment " referred to is not necessarily the same embodiment.In addition, in one or more embodiments
Special characteristic, structure or feature can be combined by any suitable form.
In conjunction with shown in Fig. 1-Fig. 4.The shredding machine of the prior art includes at least: for providing chopping processing space to food
The bottom of a cup of cup body 1, the cup body 1 is equipped with cup axle 11, across the bottom of a cup of cup body 1 that cup axle 11 is fixed from bottom to top by fixing element 12
In the bottom of a cup of cup body 1；The detachable knife assembly 2 being assemblied in cup axle 11, the knife assembly 2 include that lower end is fixed equipped with cutter shaft
The cutter shaft 21 in hole 211, the multiple shredder bars 22 being fixed on cutter shaft 21 and the lower connector 23 that end on cutter shaft 21 is set；It can
Lid closes in the cup lid 3 on cup body 1 and is fixed on the nose assembly 4 on cup lid 3 being used to rotate with moving knife component 2, the head group
The upper connector 42 for setting the motor 41 being electrical connected with external power supply in part 4 and being connected with the transmission shaft of motor 41, and on this
Connector 42 can be coupled with lower connector 23 to be connected.Therefore, user holds after nose assembly 4 removes from cup body 1, so that it may toward cup
Food is added in body 1；By the assembly of nose assembly 4 on cup body 1, allows connector 42 to couple with lower connector 23 and be connected, start
The transmission shaft of motor 41 is coupled by upper connector 42 with lower connector 23 thus with movable arbor 21 in cup axle 11 after motor 42
Rotation, carries out chopping processing to the food in cup body 1 using shredder bar 22.
When shredding machine needs to stop working during the work time (such as, during actual use need midway toward cup body 1
When interior addition chopping food materials), user from cup body 1 by removing nose assembly 4 after allowing motor 41 to stop operating, thus motor 41
The driving force that continues to rotate no longer is provided to cutter shaft 21, but cutter shaft 21 still is able to whithin a period of time because of the rotation function of itself
Keep inertia rotation, and existing safety requirement remove after nose assembly 4 cutter shaft 51 must in 1.5 seconds rotation stop with ensure using
Safety.For this purpose, innovation of the invention is, spline structure is equipped between the cutter shaft 21 and cup axle 11 of knife assembly 2, it should be only
Rotation structure includes: that cup axle 11 needs to be made of the ferrimagnets such as iron, cobalt, nickel and its alloy；Be arranged on cutter shaft 21 for pair
Cup axle 11 generates sufficiently large magnetic attraction to make cutter shaft 21 stop at the magnetic force in cup axle 11 rapidly when removing nose assembly 4
Generation device.Therefore, after motor 41 stops operating, magnetic force generation device generates sufficiently large magnetic attraction to cup axle 11, should
Magnetic attraction can not only will not separate cutter shaft 41 with cup axle 11 to prevent knife assembly 2 to be detached from cup axle 11 because of rotatory inertia
And fly out and hurt sb.'s feelings from cup body 1, while the magnetic attraction can prevent cutter shaft 41 continue to rotate make cutter shaft 41 in 1.5 seconds rapidly
It stops operating to ensure compliance with safety requirement.
Wherein, magnetic force generation device includes: the permanent-magnet material being arranged on cutter shaft 21 or/and shredder bar 22, i.e. cutter shaft 21
Or/and the partially or fully magnetization treatment of shredder bar 22 with can to cup axle 11 generate sufficient intensity magnetic attraction；Or/and
The magnet 25 of the setting that is directly or indirectly connected with the cutter shaft 21 without relative motion, generates cup axle 11 by magnet sufficiently strong
The magnetic attraction of degree.
In the 1st embodiment as Figure 1-Figure 4, shredding machine further includes the axle sleeve 24 being fixed in cutter shaft fixation hole 211,
The axle sleeve 24 be equipped with installation position, magnetic force generation device be mounted on this be installed as among and by 24 insulation package of axle sleeve in cutter shaft
In fixation hole 211, magnet 25 is avoided to contact with the food in cup body 1 to prevent contaminated food.Wherein, installation position is located at axle sleeve 24
Top or side, so that magnet 25 is located at the top of axle sleeve 24 or side；When magnet 25 is located at the side of cup axle 11, scheme
A slot position is specially opened up in the side wall of cutter shaft fixation hole 211, and magnetic force generation device is arranged in the slot.
In the 2nd embodiment as shown in Figure 5-Figure 7, directly contacted if magnet 25 has been surface-treated to have met with food
It is then not necessarily to axle sleeve 24 when safety requirement, directly magnet 25 is arranged in cutter shaft fixation hole 211, the magnet 25 and cup axle 11
Directly or indirectly contact setting.In one embodiment, magnet 25 is tube-in-tube structure, and the inner surface of magnet 25 is set in the cup
On axis 11, the outer surface of magnet 25 is in contact with the inner wall of the cutter shaft fixation hole 211.But in 21 rotation process of cutter shaft,
Cup axle 11 can cause to wear when contacting with magnetic force generation device to magnetic force generation device, be unfavorable for the long-time service of magnetic force generation device
Stable, enough magnetic attractions are kept to cup axle 11 in the process.
As shown in figure 8, magnet 25 is arranged in cutter shaft 21 in order to avoid cup axle 11 causes to wear to magnetic force generation device
And magnetic force generation device does not contact connected with cup axle 11, magnet 25 can generate magnetic attraction and will not be because of cutter shaft 21 to cup axle 11
Magnet 25 is allowed to generate abrasion in rotation process.
In another preferred embodiment of the invention, axle sleeve 24 is fixed in cutter shaft fixation hole 211, on the axle sleeve 24
Equipped with permanent-magnet material, for example, axle sleeve 24 partially or fully by permanent-magnet material, sufficiently large magnetic is generated to cup axle 11 by axle sleeve 24
Property suction can also equally to knife assembly 2 realize rotation stopping function, not need additionally on knife assembly 2 be arranged magnet 25.
To sum up, spline structure, rotation stop are equipped between the cutter shaft 21 and cup axle 11 that the present invention passes through the knife assembly 2 in shredding machine
The structure of structure is simple, generates magnetic attraction to cup axle 11 made of ferrimagnet using magnetic force generation device, utilizes magnetism
Cutter shaft 21 is sucked and is fixed in cup axle 11 by suction, and the magnetic attraction allows cutter shaft 21 to stop rapidly when removing nose assembly 4
Rotation is to meet safety requirement, it is ensured that the safety in utilization of shredding machine.
The foregoing is merely the preferred embodiments of the application, not to limit the application, all essences in the application
Made any modifications, equivalent replacements, and improvements etc., should be included within the scope of protection of this application within mind and principle.
