[0026] See also Figure 1 The food processing cup 10 may include a cup body 1, a heating plate 3, a bottom cover 2 and a plug assembly (not shown).

[0027] See also Figure 2 and Figure 6 The cup body 1 may have a bottom 11, and the bottom 11 may have an opening 12. The opening 12 may be defined by the inner edge of the bottom 11. The opening 12 is usually arranged in a circular shape.

[0028] See also Figure 4 The heating plate 3 covers the opening 12 and is fixed to the bottom 11 of the cup body 1 through the first welding connection part W1. The heating plate 3 has an opening 31, and the opening 31 can be located at the center of the heating plate 3. The first welding connection part W1 is a substantially circular weld to achieve fixation and sealing.

[0029] See also Figures 3 to 5 The bottom cover 2 may have an annular bottom 24 and an inner cylinder 22 and an outer cylinder 21 extending upward from the annular bottom 24. The annular bottom 24 and the inner cylinder 22 and the outer cylinder 21 form an annular space 23. The outer cylinder 21 is fixed under the bottom 11 of the cup body 1 through the second welding connection W2. The inner cylinder 22 is fixed under the heating plate 3 through the third welding connection W3. The inner cylinder 22 may be arranged around the outer periphery of the opening 31. The annular bottom 24 may have a through hole. The through hole may be defined by the inner edge of the annular bottom 24. The second welding connection W2 and the third welding connection W3 are also roughly circular welds to achieve fixation and sealing. The through hole described here may be one or more, and each through hole is defined by a corresponding inner edge.

[0030] The plug assembly may include an insulating portion 4 and a conductive terminal 5. The insulating portion 4 is disposed around the outer periphery of the conductive terminal 5 and fixedly coupled in the through hole. The insulating portion 4 generally wraps around the middle section of the conductive terminal 5 to expose the upper end 51 and the lower end of the conductive terminal 5 for conductive connection. The insulating portion 4 also wraps around the inner edge of the annular bottom 24 defining the through hole, so that the insulating portion 4 is tightly coupled with the inner edge of the annular bottom 24 defining the through hole, the portion adjacent to the inner edge, and the upper surface and the lower surface of the portion adjacent to the inner edge.

[0031] The first welding connection portion W1, the second welding connection portion W2, the third welding connection portion W3 and the insulating portion 4 fixedly coupled to the through hole are provided so that the annular space 23 is a sealed space. The upper end 51 of the conductive terminal is located in the annular space 23, and the lower end of the conductive terminal protrudes downward from the annular bottom 24.

[0032] The cup body 1 may also be provided with a handle 9 and a mounting portion 13 on the outer periphery of the cup body 1, and the handle 9 is fixed to the mounting portion 13 of the cup body 1 by screws. With the above structure, it is convenient for the user to directly hold the food processing cup 10 through the handle 16, and it can also prevent the user from being scalded by direct contact with the cup body 1.

[0033] The conductive terminal 5 may have a circumferential groove 52. The insulating portion 4 may include a portion filled into the circumferential groove 52. In the above manner, the insulating portion 4 can increase the holding force with the conductive terminal 5 by filling the circumferential groove 52, thereby ensuring waterproof performance and preventing loosening during repeated use to cause poor conductive contact. Of course, the circumferential groove 52 can also be replaced by grooves, bumps, etc. of any other shape and direction, which can achieve the effect of increasing the holding force.

[0034] The inner edge of the annular bottom 24 defining the through hole may have a curved portion 241. The curved portion 241 may be curved upward or downward. In the above manner, the curved portion 241 may increase the holding force with the insulating portion 4, thereby ensuring waterproof performance, and also preventing loosening during repeated use to cause poor conductive contact.

[0035] The plug assembly may further include a spring 7. The upper end 51 of the conductive terminal is electrically connected to the heating circuit of the heating disk 3 via the spring 7. In the above manner, the conductive terminal 5 is electrically connected to the heating disk 3 via the spring 7, which can prevent poor contact between the conductive terminal 5 and the heating disk 3.

[0036] The spring 7 can clamp the upper end 51 of the conductive terminal, and the insulating part 4 can include a structure for fixing and preventing the spring 7 from rotating. Specifically, the upper end of the insulating part 4 can be provided with two side walls 41 and the two side walls 41 are arranged to form a receiving groove 42. The upper end 51 of the conductive terminal is arranged in the receiving groove 42 and protrudes a distance from the bottom surface of the receiving groove 42. The upper end 51 of the conductive terminal can be provided with a clamping structure for clamping with the spring 7, such as a circumferential groove or parallel grooves only located on both sides of the upper end 51. The number of conductive terminals 5 can be set as needed, for example, 2, 3, 4 or more. The number of structures of the insulating part 4 for fixing and preventing the spring 7 from rotating is set to be the same as the number of conductive terminals 5. Figure 1 and Figure 3 FIG. 5 shows that two conductive terminals 5 are electrically connected to the heating circuit of the heating plate 3 through two spring sheets 7 .

[0037] The plug assembly may further include a grounding terminal 6, and the grounding terminal 6 may have a circumferential groove 62. The insulating portion 4 may include a portion filled into the circumferential groove 62. The grounding terminal 6 is welded to the lower surface of the annular bottom 24, and the upper end of the grounding terminal 6 is wrapped in the insulating portion 4. In the above manner, the insulating portion 4 is filled into the circumferential groove 62 to increase the holding force with the grounding terminal 6 and prevent loosening during repeated use. In addition, the grounding terminal 6 is fixed to the chassis to prevent the human body from contacting the cup body 1 and causing the risk of electric shock when leakage occurs. Of course, the circumferential groove 62 can also be replaced by grooves, bumps, etc. of any other shape and direction, which can all achieve the effect of increasing the holding force.

[0038] The food processing cup 10 may further include a stirring knife set 15. The stirring knife set 15 may include a stirring knife 151, a connecting rod 152, and a bearing 153; the stirring knife 151 is mounted on the upper end of the connecting rod 152, the bearing 153 is mounted on the connecting rod 152, and the lower end 202 of the connecting rod 152 passes through the bottom 11 of the cup body 1 and protrudes from the bottom 11 of the cup body 1. Specifically, the lower end 202 of the connecting rod 152 passes through the opening 31 fixed on the heating plate 3 of the bottom 11 of the cup body 1 and protrudes downward from the heating plate 3 of the bottom 11 of the cup body 1. The bearing 153 mounted on the connecting rod 152 is fixedly matched with the opening 31 and forms a seal.

[0039] A temperature sensor 91 and a retaining sleeve 93 may also be provided in the annular space 23. The retaining sleeve 93 is mounted on the annular bottom 24 and retains the temperature sensor 91, so that the temperature sensor 91 is in contact with the heating plate 3, thereby collecting the temperature information of the heating plate 3 in real time. Specifically, the retaining sleeve 93 may be clamped by a metal pressing sheet 92 and fixed to the bottom cover 2 by screws 94. The temperature sensor 91 is fixed on the retaining sleeve 93, so that the temperature sensor 91 is in contact with the heating plate 3. Figure 1 Two other conductive terminals 5 are shown, which can be used to achieve electrical connection with the temperature sensor 91.

[0040] In order to achieve the fixed combination of the insulating part 4 and the through hole, the insulating part 4 can be formed by injection molding. Specifically, the conductive terminals 5, the grounding terminals 6 and the bottom cover 2 can be arranged in the mold according to the correct position relationship (wherein, the conductive terminals 5 are inserted into one or more through holes of the annular bottom 24 of the bottom cover 2), and then the molten or liquid insulating material is injected into the mold cavity. After the molten or liquid insulating material is solidified, the bottom cover 2, the insulating part 4 and the conductive terminals 5 and the grounding terminals 6 can be fixedly combined. By adopting the above method, the insulating part 4, the bottom cover 2 and the conductive terminals 5 can be more tightly combined through a simple structure, and the waterproof performance can also be guaranteed.

[0041] The food processing cup 10 may further include a cup cover 17, and the cup cover 17 is used to cover the cup body 1. The above-mentioned method can effectively prevent the food from overflowing from the cup body 1 during the processing process, prevent foreign matter from entering, and reduce noise.

[0042] See also Figure 6 , shows a food processing machine 3 provided by the present invention. A support base 201 may be provided on the machine base 20, and the food processing cup 10 may be detachably mounted on the support base 201. The food processing cup 10 and the machine base 20 are separated, which is convenient for users to use, clean and move. It is also convenient for later maintenance, overhaul and replacement of parts.

[0043] The base 20 also includes a driving motor (not shown), a control circuit (not shown) and a control panel 203. The driving motor can directly or indirectly engage with the lower end 202 of the connecting rod 152 to drive the connecting rod 152 to drive the stirring blade 151 to rotate. A fixing screw column 8 can also be provided on the bottom cover 2, and the fixing screw column 8 is used to fix the base (not shown) that is buckled on the bottom cover 2. The base is partially embedded in the support seat 201 on the base 20. The driving motor provided in the support seat 201 drives the stirring blade group 15 to rotate. The control panel 203 is used to input control instructions, and the control circuit is used to receive temperature information or control instructions, and control the heating power of the heating plate 3 accordingly.

[0044] The control panel 203 may be provided with a time knob, a temperature knob, a power knob, a function (mode) selection button, a start button, a stop button, a pause button and other functions. The control panel 203 may also be provided with a display screen 204 for displaying corresponding functions and information. With the above, each function is intuitively displayed, and the user can select according to the required function, making the user operation more convenient.

[0045] The control panel 203 can also be a touch display screen. The touch display screen can not only be used as the display screen 204, but also the above-mentioned function settings can be completed on the touch display screen, and corresponding information can be displayed. For example, information such as time, temperature, power, etc. In the above manner, more rich functions can be realized in a limited space through the touch display screen, and various operations can be made more convenient and beautiful at the same time. The display screen can also be provided with a switch, and the user can turn on or off the display screen as needed after completing the function setting, which can save power.

[0046] The base 20 may also include an alarm (not shown). The alarm is electrically connected to the control circuit and is used to sound an alarm for the processing status of the food processor, such as the motor temperature is too high, the heating plate 3 temperature is too high, the work is completed, and other alarm information, and automatically light up the screen for display. The alarm sound can also be set to different frequencies or amplitudes according to different alarm information, so that the user can understand the current status of the processor in time and take timely measures. It can effectively avoid abnormal conditions and reduce failures.

[0047] When using the food processor of the present invention, a proper amount of food is placed in the cup body 1, the cup cover is put on and the food processing cup 10 is stably placed in the support base 201, and the corresponding functions and parameters are set on the control panel 203. Press the start button, and the control circuit controls the heating plate 3 to heat the food in the cup body 1 according to the set information, and the temperature sensor 91 sends the collected temperature information to the control circuit in real time and displays it on the display screen. When the preheating temperature reaches a suitable temperature, the motor starts to rotate and gradually accelerates to a predetermined speed. After several cycles of heating of the heating plate 3 and rotation of the motor, the food is minced and heated to the set temperature. When the food processing is completed, the alarm gives a prompt and stops automatically.

[0048] The present invention fixes and connects the components by welding to achieve a sealing effect, realizes a simple product structure, is easy to install, and effectively prevents water droplets from penetrating into the food processing cup 10 from the gap to damage the internal components, improves the safety of the product, thereby preventing potential safety hazards, and brings a good experience to users.
