Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to a food processing machine cup body and a food processing machine. Background Art

[0002] With the improvement of living standards, food processors with heating and pulverizing functions are becoming increasingly popular among consumers. These food processors use a brushless motor to drive the blades to pulverize ingredients. The brushless motor is integrated with the food container, with the motor output shaft directly connected to the blades. This food processor offers advantages such as a simple and reliable transmission structure and low transmission noise.

[0003] In existing food processors, the brushless motor is integrated with the cup body that holds the food ingredients to form a cup body assembly; the circuit board responsible for controlling the brushless motor is arranged in the main body for supporting the cup body assembly. The two are connected in circuit through a coupler. For example, the Chinese utility model patent with the utility model number 202322295197.3 discloses a food processor that is easy to use, which includes a main unit and a crushing cup with a built-in stirring element, a base connected to the bottom of the crushing cup and detachably arranged on the main unit, a control module and a lower coupler electrically connected to the control module are provided in the main unit, and the base is also provided with an upper coupler electrically connected to the brushless motor and the heating plate and can be coupled with the lower coupler. The coupler and the brushless motor are each provided with a lead, and the end of the lead is provided with a quick-connect terminal. The connection between the brushless motor and the coupler is achieved through the cooperation of the quick-connect terminal.

[0004] However, food processors are often used in humid kitchen environments, and water inevitably enters the cup assembly when the user cleans the machine. Moisture vapor and water droplets can accumulate on the quick-connect terminals for extended periods, causing corrosion and increased contact resistance. This can lead to brushless motor failure or even excessive heating at the connection, potentially causing personal injury. Furthermore, moisture can cause a short circuit between the terminals, resulting in sparks and electrical leakage. Utility Model Content

[0005] The purpose of the utility model is to provide a food processing machine cup body and a food processing machine, which solve the problem that the wiring structure between the brushless motor and the upper coupler is easily rusted, resulting in the welding points at the wiring falling off and the food processor being unable to work normally, under the premise of keeping the brushless motor and the upper coupler connected.

[0006] In a first aspect, an embodiment of the present invention provides a food processing machine cup body, comprising: a main body, a brushless motor arranged on the main body, and an upper coupler arranged on the main body; the upper coupler comprises a coupler terminal and a terminal lead connected to the coupler terminal; one end of the terminal lead is connected to the coupler terminal, and the other end is connected to the winding enameled wire of the brushless motor.

[0008] In an optional embodiment, the food processor cup further includes a first waterproof insulating member covering the connection between the terminal lead and the winding enameled wire.

Providing the first clamping portion and the second clamping portion as clips can facilitate installation and removal of the brushless motor lead and the terminal lead.

[0013] In an optional embodiment, the waterproof insulating portion includes a waterproof insulating heat shrink tube covering the first clamping portion and the second clamping portion.

[0014] In an optional embodiment, the waterproof insulating portion further includes insulating adhesive filled between the waterproof insulating heat shrink tubing and the metal terminal. Providing the insulating adhesive between the waterproof insulating heat shrink tubing and the metal terminal can fill the small gap between the waterproof insulating heat shrink tubing and the metal terminal, thereby reducing the corrosion effect caused by ambient moisture diffusing into the small gap between the waterproof insulating heat shrink tubing and the metal terminal.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention but merely represents selected embodiments of the present invention.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0027] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0028] The embodiment of the present invention provides a food processing machine cup and a food processing machine. The food processing machine cup can be a part of the food processing machine, and cooperates with other parts of the food processing machine to realize the function of automatic food processing. Figure 1 As shown, the food processor provided by the embodiment of the present invention may specifically include: a body 10 and a food processor cup 20 provided on the body 10. The food processor cup 20 is the food processor cup provided by some other embodiments of the present invention. The body 10 includes a brushless motor control circuit board (specifically, a chip provided at any position on the body 10). Figure 1The food processor cup 20 includes a main body 21, a brushless motor 22 disposed on the main body 21, and an upper coupler 23 disposed on the main body 21. When the food processor cup 20 is mounted on the food processor body 10, the lower coupler 11 and the upper coupler 23 are coupled to each other. When the food processor cup 20 is removed from the food processor body 10, the lower coupler 11 and the upper coupler 23 are separated from each other.

[0029] It can be understood that the upper coupler 23 and the lower coupler 11 are both couplers, one of which is set on the food processor cup body 20, and the other is set on the food processor body 10. In this application document, in order to distinguish the two, the coupler 11 set on the body 10 is referred to as the lower coupler, and the coupler 232 set on the food processor cup body 20 is referred to as the upper coupler. In actual application, the upper coupler and the lower coupler do not specifically refer to a certain type of coupler, nor do they specifically refer to the positional relationship between the two, but are only used to distinguish the setting positions.

[0030] Further, such as Figure 2 As shown, the upper coupler 23 in the food processor cup 20 provided in this embodiment of the present invention may specifically include: a coupler terminal 231 and a terminal lead 232 connected to the coupler terminal 231; the brushless motor 22 may specifically include: a motor housing 221 and a motor winding 222 disposed within the motor housing 221, and the motor winding 222 may specifically include an enameled winding wire 223. In the food processor cup 20 provided in this embodiment of the present invention, one end of the terminal lead 232 is connected to the coupler terminal 231, and the other end is connected to the enameled winding wire 223 of the brushless motor 22.

[0031] Compared with the prior art, in the food processor cup body and food processor provided by the embodiment of the present invention, the terminal lead 232 connected to the coupler terminal 231 is directly connected to the winding enameled wire 223 of the brushless motor 22, and there is no need to set an additional connecting terminal between the coupler 23 and the brushless motor 22, thereby reducing the erosion of the connection structure between the brushless motor 22 and the coupler 23 by environmental moisture, solving the problem that the wiring structure between the brushless motor 22 and the upper coupler 23 is prone to rust, resulting in the welding point at the wiring falling off and the food processor being unable to work normally, thereby improving the safety of the food processor.

[0032] Specifically, in an embodiment of the present invention, the brushless motor 22 may further include a brushless motor lead 224 extending from the winding enameled wire 223 to the outside of the brushless motor 22. That is, the winding enameled wire 223 is housed inside the motor housing 221 of the brushless motor 22, while the brushless motor lead 224 passes through the motor housing 221. One end of the brushless motor lead 224 is located inside the motor housing 221 and connected to the winding enameled wire 223, and the other end is located outside the motor housing 221 and connected to the terminal lead 232.

[0033] It can be understood that the above is only an example of a specific implementation of the brushless motor lead 224. In some other embodiments of the present invention, the brushless motor lead 224 can also be a part of the winding enameled wire 223, that is, the winding enameled wire 223 passes through the motor housing 221 and extends to the outside of the motor housing 221. The part of the winding enameled wire located outside the motor housing 221 is the brushless motor lead 224.

[0034] Furthermore, the brushless motor lead 224 and the terminal lead 232 can be connected via the metal terminal 26, as shown in FIG. Figure 3 As shown, the brushless motor lead 224 may include a first end 2241 away from the winding enameled wire 223 (corresponding to the aforementioned embodiment in which the brushless motor lead 224 is a part of the winding enameled wire 223, the first end 2241 is the end of the winding enameled wire 223 extending to the outside of the motor housing 221), and the terminal lead 232 may include a second end 2311 away from the coupler terminal 231, and the first end 2241 and the second end 2311 are connected via the metal terminal 26.

[0035] In different embodiments of the present invention, the shape of the metal terminal 26 may be different, such as Figure 3 As shown, in some embodiments of the present invention, the metal terminal 26 may include a first clamping portion 261 and a second clamping portion 262 that are connected to each other. The first end 2241 of the brushless motor lead 224 is clamped and fixed by the first clamping portion 261, and the second end 2311 of the terminal lead 232 is clamped and fixed by the second clamping portion 262. By providing two clamping portions to clamp and fix the brushless motor lead 224 and the terminal lead 232 respectively, the connection between the brushless motor lead 224 and the terminal lead 232 can be made more secure.

[0036] Furthermore, the first clamping portion 261 and the second clamping portion 262 may be connected to each other, for example, by the metal terminal 26 including a main body 263, with the first clamping portion 261 and the second clamping portion 262 being disposed on the main body 263, thereby achieving the connection between the first clamping portion 261 and the second clamping portion 262. The first clamping portion 261 and the second clamping portion 262 may be, for example, clips disposed on the main body 263. Providing the first clamping portion 261 and the second clamping portion 262 as clips facilitates installation and removal of the brushless motor lead 224 and the terminal lead 232.

[0037] In some other embodiments of the present invention, the metal terminal 26 can also be other structures, for example, it can be a conductive tubular structure, that is, a conductive tube, the first end 2241 of the brushless motor lead 224 and the second end 2311 of the terminal lead 232 are respectively inserted into the conductive tube from the two ends of the tubular structure, and the brushless motor lead 224 and the terminal lead 232 can be fixed in the conductive tube by structures such as spring clips and conductive adhesives to achieve connection between the brushless motor lead 224 and the terminal lead 232.

[0038] Further, such as Figure 3 As shown, in some other embodiments of the present invention, a waterproof insulating portion 27 may be provided around the metal terminal 26, the first end 2241 of the brushless motor lead 224, and the second end 2311 of the terminal lead 232. Specifically, the waterproof insulating portion 27 is provided around the surfaces of the metal terminal 26, the first end 2241, and the second end 2311. The first end 2241 of the brushless motor lead 224 is clamped and secured by the first clamping portion 261, and the second end 2311 of the terminal lead 232 is clamped and secured by the second clamping portion 262. Specifically, the waterproof insulating portion 27 may be provided around the surfaces of the first clamping portion 261 and the second clamping portion 262. By providing the waterproof insulating portion 27 around the metal terminal 26, the first end 2241, and the second end 2311, the corrosion resistance of the connection between the terminal lead 232 and the coupler terminal 231 can be enhanced, further improving the safety of the food processor.

[0039] Specifically, in some embodiments of the present invention, Figure 3 As shown, the waterproof insulating portion 27 may include a waterproof insulating heat shrink tube 271 covering the first clamping portion 261 and the second clamping portion 262. The shrinkage of the waterproof insulating heat shrink tube 271 upon heating allows the waterproof insulating heat shrink tube 271 to fit more closely with the first clamping portion 261 and the second clamping portion 262, thereby achieving better waterproof performance.

[0040] Furthermore, the waterproof insulating portion 27 may further include an insulating adhesive 272 that is filled between the waterproof insulating heat shrink tubing 271 and the metal terminal 26. Providing the insulating adhesive 272 between the waterproof insulating heat shrink tubing 271 and the metal terminal 26 can fill the small gap between the waterproof insulating heat shrink tubing 271 and the metal terminal 26, thereby reducing the corrosion effect caused by the diffusion of ambient moisture into the small gap between the waterproof insulating heat shrink tubing 271 and the metal terminal 26.

[0041] Furthermore, in an embodiment of the present invention, Figure 4 As shown, the connection between the terminal lead 232 and the winding enameled wire 223 is covered with a first waterproof insulating member 24. Specifically, the first waterproof insulating member 24 encases the connection between the terminal lead 232 and the winding enameled wire 223 and completely covers the surface of the connection between the terminal lead 232 and the winding enameled wire 223. The first waterproof insulating member 24 improves the corrosion resistance of the connection between the terminal lead 232 and the winding enameled wire 223, further enhancing the safety of the food processor.

[0042] Similarly, in the embodiment of the present utility model, Figure 5 As shown, the connection between the terminal lead 232 and the coupler terminal 231 is covered with a second waterproof insulating member 25. Specifically, the second waterproof insulating member 25 wraps around the connection between the terminal lead 232 and the coupler terminal 231 and completely covers the surface of the connection between the terminal lead 232 and the coupler terminal 231. The second waterproof insulating member 25 also improves the corrosion resistance of the connection between the terminal lead 232 and the coupler terminal 231, further enhancing the safety of the food processor.

[0043] Specifically, the connection between the terminal lead 232 and the winding enameled wire 223, as well as between the terminal lead 232 and the coupler terminal 231, can also be made via the aforementioned metal terminal 26. For details on the connection structure, refer to the aforementioned detailed description. Furthermore, the specific structure and materials of the first waterproof insulating member 24 and the second waterproof insulating member 25 can be substantially the same as those of the aforementioned waterproof insulating portion 27. For details, refer to the aforementioned detailed description of the waterproof insulating portion 27.

[0044] Furthermore, different connection structures can be configured for different models and types of brushless motors 22. For example, if the brushless motor 22 is a three-phase brushless motor, the three-phase brushless motor can have three brushless motor leads 224 and three terminal leads 232. In this case, the three brushless motor leads 224 and the three terminal leads 232 can be connected via three mutually insulated metal terminals 26. The three brushless motor leads 224 of the three-phase brushless motor 22 and the three terminal leads 232 of the coupler 23 are connected via three mutually insulated metal terminals 26, respectively. This reduces the possibility of interference between the different leads of the three-phase brushless motor 22, thereby improving the reliability of the food processor.

[0045] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
