[0048] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0049] 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 a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0050] 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 herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0051] The embodiment of the present invention provides a food processor, which is generally used for making various beverages, and can also be used for chopping or breaking up food.

[0052] Please refer to Figure 1 The food processor comprises a driving base 10 and a food mixing main unit 20. The food mixing main unit 20 is installed on the driving base 10. The driving base 10 is used to drive the food mixing main unit 20 to work.

[0053] The driving base 10 serves as a power source for the food processor, and its core component is a driving motor. The output shaft of the driving motor is exposed, and some connecting structures can be arranged on the output shaft.

[0054] exist Figure 1 In the example shown, a part of a clutch mechanism is provided on the output shaft of the driving motor, which is named as the lower clutch mechanism 11. The lower clutch mechanism 11 can form a transmission match with the upper clutch mechanism 21 on the food mixing host 20, so that motion can be transmitted between the two, and the motion transmission relationship can also be disconnected.

[0055] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The food mixing main unit 20 includes a cup body 100 , a machine cover 200 , a blade assembly 300 , a transition connecting piece 400 and a resetting elastic piece 500 .

[0056] The cup body 100 has a receiving cavity 101 for storing food materials, liquids, etc. A circumferential limiting structure 102 is provided at the bottom of the receiving cavity 101 .

[0057] It should be noted that the specific structure of the cup body 100 is not particularly limited. For ease of understanding and description, the relevant embodiments herein are described with reference to the cylindrical cup body 100. In addition, other structures associated with the cup body 100 are also mainly described with reference to the cylindrical shape as an example.

[0058] The circumferential limiting structure 102 here can be a part of the aforementioned upper clutch mechanism 21. At the same time, the circumferential limiting structure 102 can circumferentially limit the blade assembly 300, so that when the lower clutch mechanism 11 transmits movement to the upper clutch mechanism 21, the upper clutch mechanism 21 can drive the blade assembly 300 to operate.

[0059] The machine cover 200 can be sealed on the cup body 100. A better way is that the machine cover 200 can be sealed on the cup body 100. At this time, a closed space can be enclosed between the cup body 100 and the machine cover 200, which can ensure that the food mixing host 20 works in a safe state.

[0060] The transition piece 400 is mounted on the cover 200 in a manner that it can rotate relative to the cover 200 and is located on the side of the cup body 100 that is away from the cover 200, and the transition piece 400 can move axially relative to the cover 200. The transition piece 400 has a fastening portion 410 that penetrates the cover 200, and the transition piece 400 has at least a first stroke that enables the fastening portion 410 to be connected to the blade assembly 300 as a whole through rotation and movement, and a second stroke that enables the fastening portion 410 to be separated from the blade assembly 300 through rotation and movement. The reset elastic member 500 is disposed between the cover 200 and the transition piece 400, and is used to generate an elastic restoring force on the transition piece 400, so that the transition piece 400 can be reset in the axial direction.

[0061] Understandably, please refer to Figure 3 When the blade assembly 300 is in a normal working state, in order to avoid excessive load, the transition connector 400 is preferably separated from the blade assembly 300. At this time, the driving base 10 only drives the blade assembly 300 to rotate. When the transition connector 400 moves according to the first stroke, please refer to Figure 4 The transition piece 400 moves axially and approaches the blade assembly 300 on the one hand, and establishes a connection relationship with the blade assembly 300 through its rotation on the other hand. The transition piece 400 moves from the first initial position (the position of the transition piece 400 under normal working conditions) to the position connected to the blade assembly 300 as a whole, which is the first stroke ( Figure 4 The figure shows the state of the transition piece 400 just after the first stroke. The reset elastic member 500 applies elastic restoring force to the transition piece 400, so that the transition piece 400 performs the subsequent stroke of the first stroke. The subsequent stroke of the first stroke is the stroke of the transition piece 400 resetting in the axial direction. The second stroke can make the blade assembly 300 be limited by the circumferential limiting structure 102 again. The second stroke is similar to the first stroke, that is, the transition piece 400 needs to move axially and approach the blade assembly 300 on the one hand, and on the other hand, it needs to be disconnected from the blade assembly 300 by rotating. Please refer to Figure 5The transition piece 400 moves from the second initial position (the position of the transition piece 400 after completing the first stroke and the first subsequent stroke) to the distance from the blade assembly 300, which is the second stroke. The reset elastic member 500 applies an elastic restoring force to the transition piece 400, so that the transition piece 400 performs the subsequent stroke of the second stroke. The subsequent stroke of the second stroke is the stroke of axial reset of the transition piece 400. After the reset, the transition piece 400 is in the first initial position.

[0062] In the embodiment of the present invention, based on the arrangement of the transition connector 400 and the reset elastic member 500, the transition connector 400 has a second stroke separated from the blade assembly 300 and a first stroke connected to the blade assembly 300. Under normal conditions, the circumferential movement of the blade assembly 300 is limited by the circumferential limiting structure 102. The rotation of the blade assembly 300 can be achieved by driving the circumferential limiting structure 102 to rotate. At this time, the food mixing host 20 and the food cooking machine process the food. After the processing is completed, when the blade assembly 300 needs to be cleaned, a force can be applied to the transition connector 400 to make the transition connector 400 move according to the first stroke, and then the transition connector 400 and the blade assembly 300 will be connected as a whole, waiting to be reset. After the elastic member 500 drives the transition connector 400 to reset, the transition connector 400 will move with the blade assembly 300 and separate the blade assembly 300 from the circumferential limiting structure 102. Thereafter, the machine cover 200 can be removed from the cup body 100 to clean the blade assembly 300. After cleaning, the machine cover 200 is installed first, and then the transition connector 400 is pressed to re-establish the limiting relationship between the blade assembly 300 and the circumferential limiting structure 102. Then, the transition connector 400 is rotated in the opposite direction to make the transition connector 400 move according to the second stroke, thereby separating the blade assembly 300 from the transition connector 400. The transition connector 400 can be reset again under the action of the reset elastic member 500, and then the food can be processed again.

[0063] The food mixing host 20 and the food cooking machine in the embodiment of the present invention are designed with the transition connector 400 and the resetting elastic member 500, so that a corresponding pick-and-place relationship can be established between the blade assembly 300 and the machine cover 200. When installing and removing the machine cover 200, the blade assembly 300 can move with the machine cover 200, thereby achieving the purpose of cleaning the blade assembly 300 without human contact, and there will be no cuts to people, thereby improving the safety performance of the food cooking machine.

[0064] It can also be understood that the food mixing host 20 in the embodiment of the present invention can simplify the operation while realizing safe cleaning of the blade assembly 300. The blade assembly 300 can be cleaned by simply removing the machine cover 200. Compared with the method of first removing the machine cover 200 and then taking out the blade assembly 300, the time that the blade assembly 300 stays in the cup body 100 can be significantly shortened. Especially after making a drink, the shortened retention time can avoid reducing the taste of the drink to a certain extent.

[0065] In one embodiment, please refer to Figure 2 and Figure 6 to Figure 7 A fastening portion 410 is formed at one end of the transition piece 400 facing the cup body 100 , and the fastening portion 410 can be connected to or separated from the blade assembly 300 .

[0066] It is understandable that the fastening portion 410 needs to rotate and move together with the transition connector 400 , and the fastening portion 410 needs to be connected to the blade assembly 300 . The fastening portion 410 can be designed based on the structural characteristics of the blade assembly 300 .

[0067] exist Figure 2 and Figure 3 In the example shown, the blade assembly 300 is designed to include a blade shaft 310 and a blade 320 connected to the blade shaft 310. Based on this, the fastening portion 410 can be designed to be rod-shaped and can be surrounded by the outer periphery of the blade assembly 300. Of course, the blade assembly 300 can also be designed to have an assembly channel 301 inside, and the fastening portion 410 can extend into the assembly channel 301.

[0068] The fastening portion 410 can be formed as a part of the transition piece 400 and formed together with the transition piece 400, which can simplify the molding process and cost. Of course, the fastening portion 410 can also be an independent part and be installed on the transition piece 400 in a detachable manner, preferably coaxially connected. In this case, the fastening portion 410 is replaceable and can be used with blade assemblies 300 of various specifications and sizes.

[0069] In a specific embodiment, please refer to Figure 3 The blade assembly 300 has an internal thread 302, and the fastening portion 410 has an external thread 411, so that the blade assembly 300 and the fastening portion 410 can form a threaded connection.

[0070] It is understandable that when the transition connector 400 moves according to the first stroke, the fastening portion 410 and the blade assembly 300 are connected as a whole through a threaded connection, and when the transition connector 400 moves according to the second stroke, the fastening portion 410 and the blade assembly 300 release the threaded connection and separate.

[0071] It should be noted that when the fastening portion 410 is designed to surround the outer periphery of the blade assembly 300 , the internal thread 302 needs to be formed on the fastening portion 410 , and the external thread 411 is formed on the blade assembly 300 .

[0072] In a more specific embodiment, the internal threads 302 are spaced apart and arranged opposite to each other along the circumference of the blade assembly 300 , and the external threads 411 are spaced apart and arranged opposite to each other along the circumference of the fastening portion 410 .

[0073] Specifically, please refer to Figure 3 and 8 to Fig.10 An assembly channel 301 is formed inside the blade shaft 310 of the blade assembly 300. The inner wall surface of the assembly channel 301 radially protrudes and extends to form two semicircular connecting parts 303. The aforementioned internal thread 302 is formed on the connecting part 303. The two connecting parts 303 are separated and arranged opposite to each other along the circumferential direction, and a gap area 304 is formed between the two connecting parts 303. To match the connecting portion 303, one end of the fastening portion 410 for extending into the assembly channel 301 is flat, and the two narrow sides of the flat structure are each formed with an external thread 411. When the transition connector 400 moves according to the first stroke, the transition connector 400 can be moved axially first, and the transition connector 400 will gradually be stuck in the gap area 304 between the two connecting portions 303. Thereafter, the transition connector 400 can be rotated to achieve the connection between the fastening portion 410 and the knife shaft 310. When the transition connector 400 moves according to the second stroke, the transition connector 400 is first moved axially, and then the transition connector 400 is rotated in the opposite direction.

[0074] In this more specific embodiment, both the internal thread 302 and the external thread 411 adopt an intermittent structure, so that no matter the transition connector 400 is moved according to the first stroke or the second stroke, the transition connector 400 can be moved axially to the position and then rotated, thereby making the movement of the transition connector 400 in the overall stroke smoother and making it easier to achieve the connection or separation between the fastening part 410 and the knife shaft 310.

[0075] On this basis, it is not difficult to find some closely related deformation schemes. For example, the specific form of the interruption of the internal thread 302 and the external thread 411 can be changed. For example, the entire internal thread 302 and the external thread 411 can be designed into more sections. Correspondingly, the specific structure of the fastening part 410 can also be adaptively changed.

[0076] Of course, in other more specific embodiments, the internal thread 302 and the external thread 411 can also be designed as a continuous full-circle structure. At this time, it can be understood that when operating the transition connection piece 400 according to the first stroke or the second stroke, the rotation and axial movement of the transition connection piece 400 need to be performed synchronously.

[0077] In order to achieve assembly between the transition piece 400 and the machine cover 200 so that the transition piece 400 can rotate and move axially, the machine cover 200 and the transition piece 400 can be implemented using one of the following example structures, but it can be understood that the machine cover 200 and the transition piece 400 are not limited to the following example structures.

[0078] In one example, please refer to Figure 2 , Figure 6 to Figure 7 as well as Figure 10 to Figure 11 The machine cover 200 is provided with a through opening 201 and a support surface 202 is formed on the periphery of the through opening 201. The transition connecting piece 400 has an outer edge structure portion 420 and a central matching portion 430. The outer edge structure portion 420 can be supported on the support surface 202, and the central matching portion 430 can extend into the through opening 201. The reset elastic member 500 is arranged between the support surface 202 and the outer edge structure portion 420.

[0079] The through opening 201 is generally arranged in the center to facilitate the assembly of the transition connector 400 and ensure the appearance of the product. The support surface 202 serves as the support structure of the transition connector 400. After the reset elastic member 500 is arranged between the support surface 202 and the outer edge structure portion 420, the support surface 202 can limit the axial movement of the transition connector 400. When the transition connector 400 moves axially until the outer edge structure portion 420 and the support surface 202 abut against each other, it indicates that the axial movement is in place. At this time, the transition connector 400 can be rotated. This method is particularly suitable for the aforementioned internal thread 302 and the external thread 411 both adopting an intermittent structure. The central matching portion 430 serves as a structural portion connected to the blade assembly 300. The aforementioned fastening portion 410 can be installed on the central matching portion 430, or formed by some local structures of the central matching portion 430.

[0080] In a specific embodiment, please refer to Figure 3 , Figure 7 and Fig.10 A circle of first grooves 203 is formed on the support surface 202 , a circle of second grooves 421 is formed on the side of the outer edge structure portion 420 facing the support surface 202 , and the reset elastic member 500 is disposed in the first groove 203 and the second groove 421 .

[0081] The resetting elastic member 500 is limited by the first groove 203 and the second groove 421 , so the resetting elastic member 500 can be more stable when elastically deformed. Meanwhile, the height of the food mixing main unit 20 can be compressed as a whole by setting the first groove 203 and the second groove 421 .

[0082] In some embodiments, the resetting elastic member 500 may be a spring, and the upper and lower sides of the spring are respectively received in the second groove 421 and the first groove 203 .

[0083] In another example, the machine cover 200 is provided with a through opening 201, the transition connector 400 has a central fitting portion 430 that can extend into the through opening 201, a gap is left between the outer wall of the central fitting portion 430 and the inner wall of the through opening 201, and the reset elastic member 500 is connected between the outer wall of the central fitting portion 430 and the inner wall of the through opening 201.

[0084] Different from the above example, in this example, the resetting elastic member 500 is connected to the gap between the outer wall of the central matching portion 430 and the inner wall of the through hole 201. In this case, the resetting elastic member 500 can be an elastic cloth strip, etc., and a better way is to make it fill the gap. Of course, in the case of not considering sealing, the resetting elastic member 500 can also be other parts or devices.

[0085] On the basis of the above-mentioned related embodiments, the operation of the blade assembly 300 may be made more reliable by designing the structure.

[0086] In some embodiments, please refer to Figure 2 , Figure 3 and 10 A centering structure ring 210 is also formed on the side of the machine cover 200 facing the accommodating cavity 101. Preferably, the centering structure ring 210 is arranged at the edge of the through opening 201 and the inner wall of the through opening 201 and the inner wall of the centering structure ring 210 form the same inner wall surface. A circumferential guide assembly 600 is arranged on the centering structure ring 210, and one end of the blade assembly 300 extends into the circumferential guide assembly 600.

[0087] The inner wall of the through hole 201 and the centering structure ring 210 are arranged on the same surface so that the transition connector 400 can move freely and smoothly along the axial direction. The circumferential guide assembly 600 here is used to guide the blade assembly 300 circumferentially, so that the blade assembly 300 is more stable when rotating.

[0088] In some specific embodiments, the circumferential guide assembly 600 is fixedly mounted on the inner wall surface of the centering structure ring 210. In other specific embodiments, please refer to Fig.11The circumferential guide component 600 is restricted on the centering structure ring 210, and the centering structure ring 210 has a bottom wall 211. At the same time, a circle of limiting ribs 212 is protruded on the inner wall surface of the centering structure ring 210. The limiting ribs 212 and the bottom wall 211 of the centering structure ring 210 are respectively abutted against the upper and lower side surfaces of the circumferential guide component 600, so that the circumferential guide component 600 is restricted in the centering structure ring 210.

[0089] In some specific embodiments, the circumferential guide assembly 600 may adopt a ball bearing or the like.

[0090] In some embodiments, please refer to Figure 7 and Fig.11 A limiting portion 431 is provided on the outer periphery of the central matching portion 430 , and the limiting portion 431 is preferably a protrusion. The centering structure ring 210 is formed with a plurality of windows 213 along its circumference, and the windows 213 are used to limit the movement range and rotation range of the limiting portion 431 .

[0091] It should be noted that the specific structure of the window 213 is not limited, and it can be rectangular, elliptical or other shapes.

[0092] Taking the rectangular window 213 as an example, the limiting portion 431 is inserted into the window 213 and can move axially between the upper side wall 2131 and the lower side wall 2132 of the window 213 and can rotate circumferentially between the left side wall 2133 and the right side wall 2134 of the window 213.

[0093] In a normal state, the limiting portion 431 abuts against the upper side wall 2131 of the window 213 under the action of the reset elastic member 500, and is close to the left side wall 2133 or abuts against the left side wall 2133. At this time, the blade assembly 300 and the transition connector 400 are in a separated state; after the transition connector 400 moves according to the first stroke, the limiting portion 431 abuts against the lower side wall 2132 of the window 213, and is close to the right side wall 2134 or abuts against the right side wall 2134; after the transition connector 400 moves according to the subsequent stroke of the first stroke, the limiting portion 431 abuts against the lower side wall 2132 of the window 213, and is close to the right side wall 2134 or abuts against the right side wall 2134. The limiting portion 431 abuts against the upper side wall 2131 of the window 213, and is close to the right side wall 2134 or abuts against the right side wall 2134; after the transition connecting piece 400 moves according to the second stroke, the limiting portion 431 abuts against the lower side wall 2132 of the window 213, and is close to the left side wall 2133 or abuts against the left side wall 2133; after the transition connecting piece 400 moves according to the subsequent stroke of the second stroke, the limiting portion 431 abuts against the upper side wall 2131 of the window 213, and is close to the left side wall 2133 or abuts against the left side wall 2133.

[0094] It should be noted that the specific size of the window 213 can be designed according to factors such as the discontinuous distance of the discontinuous thread or the axial movement stroke of the transition connector 400 mentioned above. Preferably, when the limiting portion 431 rotates from the left wall 2133 to the right wall 2134, the fastening portion 410 just rotates from the idle area 304 to the internal thread 302.

[0095] In some embodiments, please refer to Figures 2 to 3 , Figure 7 An axial floating pseudo component 700 that can press against the blade assembly 300 can also be provided. The axial floating pseudo component 700 is connected to the machine cover 200 and is used to reduce the axial movement of the blade assembly 300 during operation.

[0096] In some specific embodiments, the central matching portion 430 is a hollow structure, and a rod-shaped fastening portion 410 is arranged inside the central matching portion 430. The blade assembly 300 has an assembly channel 301, and a step 305 is formed in the assembly channel 301. The fastening portion 410 can extend into the assembly channel 301. The axial floating simulated assembly 700 includes a simulated elastic member 710 and a pressing plate 720 through which the fastening portion 410 can pass. The simulated elastic member 710 surrounds the outer periphery of the fastening portion 410 and is connected to the pressing plate 720, and the pressing plate 720 is pressed against the step 305.

[0097] The pressing plate 720 always abuts against the step 305. In each stage of the transition connector 400, the pressing force generated by the pressing plate 720 on the blade assembly 300 can prevent the blade assembly 300 from axial movement during operation, so that the blade assembly 300 can operate more stably.

[0098] It is understandable that by changing the structure of the blade assembly 300 , for example, providing a force-bearing platform on the periphery of the blade assembly 300 , the aforementioned axial floating simulated assembly 700 can also act on the outside of the blade assembly 300 .

[0099] In combination with the above, the food mixing main unit 20 preferably includes a closed space to prevent leakage during operation.

[0100] In this regard, in some embodiments, please refer to Figure 3 and Fig.11A circle of latching structures 220 are formed at the edge of the cover 200, and latching grooves 221 are evenly formed on the latching structures 220. A plurality of latching protrusions 110 that can be correspondingly latched into the latching grooves 221 are formed on the inner wall surface of the cup body 100. The connection between the cover 200 and the cup body 100 can be achieved through the cooperation of the latching grooves 221 and the latching protrusions 110. In addition, a sealing ring 800 with a certain thickness is also arranged on the periphery of the latching structure 220. The sealing ring 800 is located between the inner wall surface of the cup body 100 and the latching structure 220. The sealing ring 800 and the latching structure 220 can form two seals to prevent liquid leakage.

[0101] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
