[0025] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0026] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] As shown in Figures 1 to 6, a blender according to an embodiment of the present invention is used for juicing fruits and vegetables, and has the advantages of being safe to use and having low operating noise.

[0029] A driving module 11 is provided inside the base 10 , a driving shaft 12 is extended from the upper end of the driving module 11 , and a magnetic driving member 13 is fixed to the outer side of the upper end of the driving shaft 12 ; and a sensing component 30 is installed on the base 10 .

[0030] A stirring module is provided in the stirring container 20; in this embodiment, the stirring module includes a cutter 23; the cutter 23 has a cutter shaft 24, and a magnetic follower 25 is fixedly provided at the lower end of the cutter shaft 24; the magnetic follower 25 corresponds to the position of the magnetic driving member 13 and is arranged at intervals.

[0031] In this embodiment, the drive module 11 is a motor. The drive module 11 drives the drive shaft 12 to rotate the magnetic drive member 13. A magnetic field exists between the magnetic drive member 13 and the magnetic follower 25. When the magnetic drive member 13 rotates, under the action of the magnetic field, the magnetic follower 25 and the knife shaft 24 rotate 360 ​​degrees along with the rotation of the magnetic drive member 13, ultimately achieving the rotation of the knife 23, thereby squeezing the juice from the fruits and vegetables. The transmission between the drive module 11 and the knife 23 is achieved through the above-mentioned electromagnetic induction, which can avoid the working noise generated by mechanical transmission. When the drive module 11 drives the magnetic drive member 13 to rotate, a magnetic field is generated between the magnetic drive member 13 and the magnetic follower 25. The magnetic induction intensity of the magnetic field is 1000-4500 gauss, thereby ensuring the transmission between the magnetic drive member 13 and the magnetic follower 25.

[0032] In this embodiment, the induction component 30 uses a magnetic induction sensor, specifically a reed switch, and the magnetic component 40 uses an induction magnet 41. Please refer to Figure 7. When the stirring container 20 is placed on the base 10, the induction component 30 and the magnetic component 40 are close to each other to a distance less than or equal to 10 mm. Within this distance, the induction component 30 can sense the magnetic component 40; the magnetic follower 25 corresponds to the position of the magnetic driving component 13 and is arranged at a distance. The driving module 11 is used to drive the magnetic driving component 13 to rotate to drive the magnetic follower 25 to rotate, thereby driving the tool 23 to rotate; after the induction component 30, i.e., the reed switch, senses the magnetic field of the magnetic component 40, it outputs a power-on control signal, and the driving module 11 is powered to allow the driving module 11 to start operation;

[0033] When the stirring container 20 is detached from the base 10 , the sensing component 30 does not sense the magnetic component 40 , and outputs a power-off control signal to the outside, thereby powering off the driving module 11 to prohibit the driving module 11 from operating, thereby ensuring safety in use.

[0034] A further improvement to the above scheme is that both the magnetic driver 13 and the magnetic follower 25 are disc-shaped magnets for easy rotation. At the same time, the distance between the magnetic driver 13 and the magnetic follower 25 is 4-8 mm to ensure sufficient magnetic induction intensity to achieve transmission.

[0035] Furthermore, a first connecting column 121 extends from the upper end of the drive shaft 12, and the magnetic drive member 13 is sleeved on the outside of the first connecting column 121. A first nut 14 is provided on the outside of the first connecting column 121, and the first nut 14 is used to lock the magnetic drive member 13. A second connecting column 241 extends from the lower end of the knife shaft 24, and the magnetic follower 25 is sleeved on the outside of the second connecting column 241. A second nut 26 is provided on the outside of the second connecting column 241, and the second nut 26 is used to lock the magnetic follower 25. Through the above-mentioned locking method, the rotational balance and concentricity of the drive shaft 12 and the knife shaft 24 can be ensured, and the working noise can be further reduced. The magnetic drive member 13 and the magnetic follower 25 are both provided with a groove 131, and the first nut 14 and the second nut 26 are both provided in the groove 131 to avoid affecting the magnetic field between the magnetic drive member 13 and the magnetic follower 25, thereby ensuring the rotation speed.

[0036] A further improvement to the above solution is that the magnetic component 40 includes a plurality of induction magnets 41 distributed in a circular array within the cup base 22 , and the induction component 30 is specifically a magnetic induction sensor.

[0037] A further improvement to the above solution is shown in FIG6 . A mixing container 20 includes a cup body 21 and a cup base 22 fixed to the lower end of the cup body 21; the cup body 21 is made of glass. The cup base 22 includes a connecting base 221 disposed at the lower end of the cup body 21 and a connecting ring 222 connected to the connecting base 221. The inner side of the connecting ring 222 is threadedly connected to the cup body 21. A blade shaft 24 is disposed within the connecting base 221. The upper end of the blade shaft 24 extends through the connecting base 221 and connects to the blade 23.

[0038] A further improvement to the above scheme is that a rotating bearing 50 is sleeved on the outer side of the knife shaft 24, and the rotating bearing 50 is fixedly connected to the connecting seat 221; in addition, as shown in Figure 6, a circular receiving portion 223 is provided on the inner wall of the connecting ring 222, and a placement groove 224 is recessed on the upper end surface of the receiving portion 223. The magnetic component 40 is placed in the placement groove 224 for fixation. The magnetic component 40 is placed inside the cup holder 22 to avoid contact with the outside world, reduce losses, and increase service life.

[0039] A further improvement to the above scheme is that a boss 15 is provided on the upper end of the base 10, and the magnetic induction sensor is arranged on the inner side of the boss 15. Correspondingly, a positioning piece 225 extends downward from the stirring container 20, and the positioning piece 225 is arranged on the outer side of the boss 15. The boss 15 and the positioning piece 225 cooperate to limit the shaking of the stirring container 20, thereby ensuring stable juicing operation.

[0040] A further improvement to the above solution is that a support seat 16 is provided at the bottom of the inner side of the base 10 , and the driving module 11 is assembled on the support seat 16 to fix the driving module 11 .

[0041] The blender of this embodiment is provided with a base 10 and a mixing container 20, and a driving module 11, a driving shaft 12 and a magnetic driving member 13 are provided in the base 10, and a knife shaft 24 and a magnetic follower 25 are provided in the body. The magnetic driving member 13 and the magnetic follower 25 realize transmission through electromagnetic induction to avoid the working noise of mechanical transmission. The magnetic driving member 13 and the magnetic follower 25 both adopt disc-shaped magnets. In addition, the magnetic driving member 13 and the driving shaft 12, the magnetic follower 25 and the knife shaft 24 are coaxially arranged to ensure the rotation balance of the knife 23 and improve stability; in addition, an induction component 30 and a magnetic component 40 are also provided, specifically, the induction magnet 41 sensor and the induction magnet 41 constitute a safety locking device. When cleaning the cup body 21, the magnetic induction sensor cannot sense the induction magnet 41, thereby realizing power failure of the driving module 11 and the inability to start the knife 23, thereby ensuring safe use.

[0042] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
