[0035] The present application provides a food processor for cutting, mixing, stirring, grinding and other processing of food raw materials. According to different functions and designs, food processors can be divided into various types, including but not limited to mixers, meat mincers, shredders, and noodle machines. The present application takes a meat mincer as an example for explanation.

[0036] See also Figure 1 and Figure 2 The food processing machine 100 provided in the present application includes a main machine 1, a speed regulating unit 2 and a processing unit 3. Figure 2 and Figure 3 The host 1 includes a housing 11, a motor 12 and a circuit board 13. The circuit board 13 is used to connect and control the motor 12. An adjustable resistor 14 is provided on the circuit board 13. The speed regulating unit 2 includes a rotating shaft 21, a connecting member 22 and a rotating ring 23. The rotating shaft 21 is arranged along a first direction ( Figure 2 The rotating ring 23 is rotatably disposed on the housing 11. The rotating ring 23 is sleeved on the periphery of the circuit board 13 and connected to the rotating shaft 21 through the connecting member 22. The rotating ring 23 is used to drive the rotating shaft 21 to rotate around the first direction. Figure 2 and Figure 4 The processing unit 3 includes a barrel 31 and a blade assembly 32 disposed in the barrel 31 , and the blade assembly 32 is connected to the output shaft of the motor 12 .

[0037] The circuit board 13 is used to send electrical signals to the motor 12 to control the start, stop, speed and rotation direction of the motor 12. The adjustable resistor 14 is a rotary resistor. When the shaft 21 rotates, the contact point with the resistor changes, thereby changing the resistance value of the circuit, so that the current or voltage in the circuit changes.

[0038] The user manually rotates the rotating ring 23 to drive the connecting member 22 and the rotating shaft 21 to rotate together. Since the rotating angles of the rotating ring 23 and the rotating shaft 21 change continuously, the resistance value of the adjustable resistor 14 changes continuously, and the speed of the motor 12 also changes continuously, realizing stepless speed regulation.

[0039] The barrel 31 is used to place food materials to be processed, and its capacity and shape can be selected according to usage requirements.

[0040] In the food processor 100 provided in the present application, an adjustable resistor 14 is arranged on the circuit board 13 in the host 1, and the speed regulating unit 2 comprises a rotating shaft 21, a connecting member 22 and a rotating ring 23. The rotating shaft 21 is inserted into the adjustable resistor 14, and the rotating ring 23 is connected to the rotating shaft 21 through the connecting member 22. The user can rotate the rotating ring 23 to drive the rotating shaft 21 to rotate in the adjustable resistor 14, thereby adjusting the access resistance value of the adjustable resistor 14 and realizing the speed regulation of the motor 12 and the blade assembly 32; at the same time, since the rotation angles of the rotating ring 23 and the rotating shaft 21 change continuously, the access resistance of the adjustable resistor 14 can be continuously changed by controlling the rotation angle of the rotating ring 23, thereby realizing the stepless speed regulation of the motor 12 and the blade assembly 32. The above-mentioned food processor 100 has a stepless speed regulation function, allowing the user to freely select a suitable speed according to the characteristics of the processed food and the processing requirements, thereby improving the flexibility and applicability of the food processor 100.

[0041] In some embodiments, see Figure 5 , Figure 6 and Figure 7 The connecting member 22 includes a connecting body 221 and a connecting rod 222 , one end of the connecting rod 222 is connected to the outer circumference of the connecting body 221 , and the other end is connected to the inner edge of the rotating ring 23 , and the rotating shaft 21 is fixedly arranged at the center of the connecting body 221 .

[0042] The rotating ring 23 is rotatably disposed on the housing 11 and can be used as a component of the entire housing of the food processor 100. The connecting rod 222 is used to connect the connecting body 221 and the rotating ring 23, which is conducive to improving the rationality of the layout of the main body 1 and the speed regulating unit 2, and avoiding interference between the internal components of the speed regulating unit 2 during use.

[0043] It can be understood that in some embodiments, the connecting body 221 can also be directly connected to the rotating ring 23, and the specific design can be made according to actual conditions, which is not limited here.

[0044] There is no unique way to connect the shaft 21 to the connecting body 221. Optionally, in some embodiments, the shaft 21 can be inserted into the connecting body 221 through a slot or other structure; or, in some embodiments, the shaft 21 and the connecting body 221 are both plastic parts and are integrally formed by injection molding.

[0045] The connection method between the connection body 221 and the connection rod 222 is not unique. Optionally, in some embodiments, the connection body 221 and the connection rod 222 are fixedly connected by fasteners; or, in some embodiments, the connection body 221 and the connection rod 222 are both plastic parts and are integrally formed by injection molding.

[0046] In some embodiments, see Figure 5 and Figure 6 In order to improve the connection strength between the rotating member and the connecting ring, the connecting member 22 is designed with at least two connecting rods 222, and the at least two connecting rods 222 are arranged at intervals around the outer circumference of the connecting body 221.

[0047] In some embodiments, see Figure 5 , Figure 6 and Figure 7 The connecting body 221 is circular, and a tooth groove is arranged on the outer peripheral surface of the connecting body 221. The speed regulating unit 2 also includes a gear spring 24 arranged in the housing 11. When the connecting body 221 rotates, the gear spring 24 can contact the tooth groove.

[0048] Specifically, a fixed structure such as a baffle 15 or a mounting plate 16 is further disposed inside the housing 11 of the host 1 , and the shift spring 24 is disposed on the fixed structure, and a free end of the shift spring 24 abuts against the tooth groove of the connecting body 221 .

[0049] On the one hand, the circular connecting body 221 is evenly stressed and has high stability during rotation; on the other hand, the gear spring 24 is configured to be in contact with the connecting body 221, which can provide the user with a clear sense of feedback, thereby improving the user's operating feel. In some cases, when the connecting body 221 rotates, the gear spring 24 cooperates with the tooth groove and makes a sound, providing instant feedback to the user.

[0050] In some embodiments, see Figure 5 , Figure 6 and Figure 8 A baffle 15 is arranged between the connecting member 22 and the circuit board 13, and a first avoidance hole 151 is arranged on the baffle 15. The connecting rod 222 is connected to the rotating ring 23 through a fastener 223. The fastener 223 extends along the first direction and penetrates into the first avoidance hole 151. The fastener 223 can reciprocate in the first avoidance hole 151 around the circumference of the connecting body 221.

[0051] The fasteners 223 include, but are not limited to, screws and bolts.

[0052] The fastener 223 is connected to the inner edge of the rotating ring 23, and the moving track of the fastener 223 is a circular arc centered on the rotating shaft 21. Accordingly, the first avoidance hole 151 is designed to be circular arc-shaped.

[0053] On the one hand, the first avoidance hole 151 is used to limit the moving trajectory of the fastener 223 to further improve the stability of the rotating part; on the other hand, the first avoidance hole 151 is also used to limit the movable range of the fastener 223, thereby limiting the rotation angle of the rotating ring 23, the connecting part 22 and the rotating shaft 21, thereby realizing the control of the variation range of the adjustable resistor 14.

[0054] In some embodiments, the connecting member 22 is disposed on a side of the circuit board 13 away from the adjustable resistor 14 , and a second avoidance hole (not shown) for the rotating shaft 21 to pass through is also disposed on the circuit board 13 .

[0055] The rotating shaft 21 is spaced apart from the side wall of the second avoidance hole, and the rotating shaft 21 can rotate freely in the second avoidance hole.

[0056] The connection member 22 and the circuit board 13 are arranged reasonably, which is beneficial to improving the space efficiency of each component.

[0057] In some embodiments, see Figure 3 and Figure 4 A mounting plate 16 is provided in the shell 11. The food processor 100 also includes a switch unit 4, which includes a pressing panel 41, a return spring 42 and a micro switch 43. The pressing panel 41 is movably provided on the shell 11 and can move along a first direction. One end of the return spring 42 abuts against the mounting plate 16, and the other end abuts against the inner surface of the pressing panel 41. The micro switch 43 is provided on the side of the circuit board 13 facing the pressing panel 41.

[0058] The micro switch 43 is a small electromechanical switch that can be used to detect small movements or position changes and quickly switch a circuit when triggered.

[0059] The pressing panel 41 can be made of metal or plastic, but is not limited thereto. The outer surface of the pressing panel 41 can be designed with indicator symbols, signal lights, etc. It can be understood that the portion of the pressing panel 41 extending into the housing 11 is also provided with a limiting structure 411 that cooperates with the housing 11, such as an elastic insert, a limiting hook, etc. The limiting structure 411 is used to limit the relative position of the pressing panel 41 and the housing 11 in the first direction to prevent the pressing panel 41 from being separated from the housing 11.

[0060] The user manually operates the pressing panel 41 to move the pressing panel 41 toward the micro switch 43. When the pressing panel 41 contacts the button or operating rod of the micro switch 43, the mechanical structure inside the micro switch 43 is activated, thereby connecting or disconnecting the circuit. It is understood that the inner surface of the pressing panel 41 can directly contact the micro switch 43, or a convex structure opposite to the micro switch 43 can be designed on the inner surface of the pressing panel 41, and the convex structure can contact the micro switch 43.

[0061] The push switch unit 4 has high sensitivity, is durable and is not easily damaged.

[0062] It can be understood that in some embodiments, the switch unit 4 can be designed as a touch switch, a toggle switch or a sliding switch, and the specific design can be based on actual conditions and is not limited here.

[0063] In some embodiments, a sealing ring structure is provided between the pressing panel 41 and the housing 11 to enhance the waterproof and dustproof performance of the device.

[0064] In some embodiments, see Figure 2 The housing 11 includes an inner shell 111 and an outer shell 112 , wherein the outer shell 112 is sleeved on the outside of the inner shell 111 , and the mounting plate 16 and the baffle 15 are formed on the inner shell 111 .

[0065] In some embodiments, see Figure 2 A first limiting column 161 is provided on the mounting plate 16 , and one end of the return spring 42 is sleeved on the first limiting column 161 .

[0066] The first limiting column 161 is used to fix the return spring 42 , which can prevent the return spring 42 from being separated from the mounting plate 16 and prevent the return spring 42 from being offset or misplaced during repeated pressing, thereby improving the stability and return accuracy of the return spring 42 .

[0067] In some embodiments, see Figure 2 and Fig. 9 A second limiting column 412 is designed on the inner surface of the pressing panel 41 , and one end of the return spring 42 is sleeved on the second limiting column 412 .

[0068] Optionally, in a specific embodiment, a first limiting column 161 is provided on the mounting plate 16, and the inner surface of the pressing panel 41 is designed with a second limiting column 412 opposite to the first limiting column 161, and one end of the return spring 42 is sleeved on the first limiting column 161, and the other end is sleeved on the second limiting column 412.

[0069] By designing the second limiting column 412 , the return spring 42 can be prevented from being separated from the pressing panel 41 , thereby further improving the reliability of the return spring 42 .

[0070] In some embodiments, a third avoidance hole may be designed in the first limiting column 161 , the second limiting column 412 is inserted in the third avoidance hole, and the second limiting column 412 can move in the third avoidance hole along the first direction.

[0071] With such a design, the first limiting post 161 and the second limiting post 412 are used together and also have a guiding function, thereby preventing the pressing panel 41 from being offset or misaligned during repeated pressing, thereby improving the reliability of the pressing panel 41.

[0072] In some embodiments, the switch unit 4 includes a plurality of return springs 42 , and the plurality of return springs 42 are disposed at intervals on the mounting plate 16 .

[0073] Optionally, in a specific embodiment, see Figure 2 , the switch unit 4 includes three return springs 42 .

[0074] On the one hand, setting up multiple return springs 42 can effectively increase the return force, so that the pressing panel 41 can be reset faster; on the other hand, setting multiple return springs 42 at intervals can improve the uniformity of the force on the pressing panel 41, so that the pressing panel 41 can stably return to its initial position.

[0075] In some embodiments, see Figure 3 and Fig.10 The blade assembly 32 includes a mounting shaft 321 and a plurality of blades 322 , and the plurality of blades 322 are detachably sleeved on the mounting shaft 321 .

[0076] Optionally, in a specific embodiment, see Fig.10 , Fig.11 and Fig.12 , three blade shafts 323 are sleeved on the installation shaft 321, and three blades 322 are arranged at intervals on each blade shaft 323. A matching clamping structure 324 is arranged on the side wall of the installation shaft 321 and the inner wall of the blade shaft 323. After the blade shaft 323 is sleeved on the installation shaft 321, it can be locked or unlocked by rotating around the circumference of the installation shaft 321. The clamping structure 324 includes but is not limited to a limit block and a limit groove.

[0077] By adopting the above design, the number of blades 322 can be increased or decreased according to the processing requirements of the food, thereby further improving the flexibility and practicality of the food processor 100.

[0078] In summary, the food processor 100 provided in the present application has a stepless speed regulation function, allowing the user to freely select a suitable speed according to the characteristics of the processed food and processing requirements, while allowing the number of blades 322 to be increased or decreased, which has higher flexibility and applicability than similar products.
