[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0042] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0043] Embodiments of this application provide a juicer, such as Figures 1-2 As shown, the juicer includes a main unit 100 and a cup body 200. A motor 300 is installed inside the main unit 100, and a spiral juicing head 500 is installed inside the cup body 200. A receiving cavity 501 is installed inside the spiral juicing head 500. A gearbox 600 is installed on the rotating shaft 310 of the motor 300. The gearbox 600 is at least partially housed in the receiving cavity 501. The gearbox 600 located in the receiving cavity 501 includes at least an output shaft 610 and an output shaft positioning member for positioning the output shaft 610. The output shaft 610 is connected to the spiral juicing head 500.

[0044] In this embodiment of the application, the juicer has a receiving cavity 501 provided in the spiral juicing head 500, and the gearbox 600 is at least partially housed in the receiving cavity 501, which increases the contact area between the output shaft 610 and the spiral juicing head 500. At the same time, the gearbox 600 located in the receiving cavity 501 includes at least one output shaft 610 and an output shaft positioning member. The output shaft positioning member is used to improve the stability of the output shaft 610, reduce the shaking generated when the output shaft 610 rotates, reduce noise, and improve the user experience.

[0045] The spiral juicing head 500 includes a main body and spiral ribs on the outer surface of the main body. The spiral juicing head 500 rotates under the drive of the output shaft 610. By cooperating with the inner wall of the cup body 200, it slowly grinds and squeezes the chopped fruits and vegetables to extract juice and pushes them forward, thus extracting the juice from the fruits and vegetables.

[0046] Furthermore, it is understandable that by providing a receiving cavity 501 within the spiral juicing head 500, and at least partially housing the gearbox 600 within the receiving cavity 501, the overall height of the juicer can be shortened, resulting in a more compact structure and facilitating product miniaturization.

[0047] In one embodiment, such as Figures 2-3 As shown, the rotating shaft 310 and the output shaft 610 are coaxially arranged.

[0048] This design ensures that the spiral juicing head 500 and the rotating shaft 310 of the motor 300 are coaxially arranged, which can guarantee that the juicer is subjected to uniform force when it is working.

[0049] In an embodiment, the material of the output shaft 610 is different from the material of the output shaft positioning member. With this design, the friction coefficient of the same material is the same, which is easy to cause the output shaft 610 and the output shaft positioning member to wear.

[0050] Specifically, the output shaft positioning member can be made of a hard material, such as a hard alloy.

[0051] In an embodiment, in the radial direction of the output shaft 610, the outer side of the output shaft 610 is less than or equal to 30 mm from the output shaft positioning member. With this design, the positioning effect of the output shaft positioning member on the output shaft 610 is improved. In theory, the smaller the distance between the output shaft 610 and the output shaft positioning member, the better the positioning effect.

[0052] In an embodiment, as shown in Figure 2 The transmission 600 has a planetary gear mechanism 620 arranged between the output shaft 610 and the output shaft 610.

[0053] It can be understood that the output shaft 610 is a hollow shaft in a cylindrical shape, and the planetary gear mechanism 620 is arranged in the radial space between the output shaft 610 and the output shaft 310. The structure is compact, and at the same time, the corresponding components in the planetary gear mechanism 620 that are arranged between the output shaft 610 and the output shaft 610 can be used as the output shaft positioning member to improve the stability between the output shaft 610 and the output shaft 310, and reduce the shaking generated when the output shaft 610 and the output shaft 310 rotate at high speed.

[0054] Of course, it is conceivable that the planetary gear mechanism 620 can also be replaced by other speed reduction mechanisms, which are not limited here.

[0055] In a specific embodiment, as shown in Figure 3 and Figure 5 The planetary gear mechanism 620 includes a first gear 621, a ring gear 622, a first planetary gear 623, a first planetary carrier 624, a second gear 625, a second planetary gear 626, and a second planetary carrier 627. The first gear 621 is fixed to the output shaft 310, the ring gear 622 is arranged between the output shaft 310 and the output shaft 610, the first planetary carrier 624 and the second planetary carrier 627 are located in the ring gear 622 and are respectively rotatably connected to the output shaft 310, the second gear 625 is fixed to the first planetary carrier 624, a plurality of first planetary gears 623 are rotatably arranged on the first planetary carrier 624 and are all engaged with the first gear 621 and the ring gear 622, a plurality of second planetary gears 626 are rotatably arranged on the second planetary carrier 627 and are all engaged with the second gear 625 and the ring gear 622, the second planetary carrier 627 is fixedly connected with the output shaft 610, and the second planetary carrier 627 and / or the ring gear 622 constitute the output shaft positioning member.

[0056] The second carrier 627 and the ring gear 622 in the planetary gear mechanism 620 are used as an output shaft positioning member for supporting the positioning rotating shaft 310 and the output shaft 610, and no other positioning structure is needed, so that the structure is simpler.

[0057] In this embodiment, the first gear 621, the ring gear 622, the first planetary gear 623, the first carrier 624, the second gear 625, the second planetary gear 626 and the second carrier 627 constitute a two-stage planetary deceleration mechanism. It can be understood that in other embodiments, a one-stage or three-stage planetary deceleration mechanism can also be provided according to the speed change requirement, which is not limited herein.

[0058] In one embodiment, as shown in Figure 2 and Figure 3 , the juicer further comprises a cutting knife 400 arranged in the cup body 200 and above the spiral juicing head 500, and the rotating shaft 310 penetrates the speed changer 600 and is connected to the cutting knife 400.

[0059] According to the above design, the rotating shaft 310 of the motor 300 penetrates the speed changer 600 and drives the cutting knife 400 to rotate, so that the fruits and vegetables are cut, and then the output shaft 610 of the speed changer 600 drives the spiral juicing head 500 to rotate, so that the cut fruits and vegetables are squeezed to extract juice. When the juicer works, the fruits and vegetables put into the cup body 200 are first cut by the cutting knife 400, and then squeezed by the spiral juicing head 500 to extract juice. The cutting knife 400 and the spiral juicing head 500 cooperate with each other to improve the juicing efficiency.

[0060] Specifically, the cutting knife 400 divides the inside of the cup body 200 into an upper cutting cavity and a lower squeezing cavity, and a gap is arranged between the circumferential side of the cutting knife 400 and the inner wall of the cup body 200. The gap forms an annular discharge port for vertically connecting the upper cutting cavity and the lower squeezing cavity, so that the juicing materials in the upper cutting cavity cut by the cutting knife 400 can directly fall into the squeezing cavity through the annular discharge port, facilitating the discharge and further improving the juicing efficiency of the juicer.

[0061] In one specific embodiment, please continue to refer to Figure 3 and Figure 5 , the rotating shaft 310 comprises a first output section 311 and a second output section 312 connected to each other, the first output section 311 is close to the main machine 100, and the second output section 312 is away from the main machine 100. The first output section 311 is connected to the input part (specifically, the input part is the first gear 621 in the planetary gear mechanism 620) of the speed changer 600, and the second output section 312 extends out of the speed changer 600 and is connected to the cutting knife 400.

[0062] Specifically, for the convenience of production and processing, the first gear 621 can be in an integral structure with the first output section 311.

[0063] In a more specific embodiment, as shown in Figures 3-5 The second coupling part 700 is arranged above the second output section 312, and the first coupling part 800 is arranged below the cutting knife 400. The first coupling part 800 is coupled to the second coupling part 700, and the diameter of the coupling part of the first coupling part 800 and the second coupling part 700 is 15-100 mm.

[0064] It can be understood that the larger the coupling area of the first coupling part 800 and the second coupling part 700, the more stable the transmission, the finer and more uniform the cutting of the food material. Moreover, the noise during operation is smaller, and the product life is longer. However, too large coupling area will result in large volume of the first coupling part 800 and the second coupling part 700, affecting the product size, and poor economy. Therefore, considering comprehensively, the diameter of the coupling part of the first coupling part 800 and the second coupling part 700 is 15-100 mm.

[0065] In a specific embodiment, as shown in Figure 3 and Figure 4 The mounting hole 502 is arranged at the upper end of the spiral juicer head 500 and communicates with the accommodating cavity 501. The bearing 900 is arranged in the mounting hole 502. The connecting shaft 410 of the cutting knife 400 is connected to the rotating shaft 310 and is rotatably arranged in the bearing 900. Thus, the relative rotation stability between the cutting knife 400 and the spiral juicer head 500 is improved.

[0066] In a specific embodiment, the rotating speed of the rotating shaft 310 is greater than the rotating speed of the output shaft 610.

[0067] Since the rotating shaft 310 directly drives the cutting knife 400, high-speed cutting can be realized. The spiral juicer head 500 is connected to the output shaft 610 of the transmission 600, and the rotating speed of the rotating shaft 310 of the motor 300 is reduced by the transmission 600 to drive the spiral juicer head 500 to realize low-speed extrusion. By first cutting at high speed and then juicing at low speed, the structure is simple and reasonable, the juicing speed is fast, the vibration is small, the noise is low, and the application range is wide.

[0068] In a specific embodiment, the ratio of the rotating speed of the rotating shaft 310 to the rotating speed of the output shaft 610 is 5-1000.

[0069] Since the working process of the juicer is divided into fast cutting first and slow spiral extrusion later, when the cutting speed of the cutting knife 400 is greater than the pressing speed of the spiral juicing head 500, food accumulation will occur inside the cup body 200 and the material cannot be discharged; when the cutting speed of the cutting knife 400 is lower than the extrusion speed of the spiral juicing head 500, the overall juicing speed is affected, the power consumption is increased, etc. In order to more reasonably balance the juicing speed and the juicing effect, the working efficiency of the cutting knife 400 and the spiral juicing head 500 must be mutually coordinated to achieve the optimization of the juicing efficiency, therefore, the speed ratio of the rotating shaft 310 and the output shaft 610 is set to 5-1000. Preferably, the speed ratio of the rotating shaft 310 and the output shaft 610 is set to 20-200.

[0070] In some embodiments, the size of the accommodating cavity 501 in the axis direction of the rotating shaft 310 is greater than or equal to 20mm. With this design, sufficient space is reserved for accommodating structures such as the transmission 600.

[0071] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0072] The above embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, however, it should not be understood as the limitation of the scope of the application. It should be pointed out that, for ordinary skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
