The host 101 is in the form of a base. The host 101 can provide electrical energy, control and drive the food processor 1 to work, and can interact with the user.

[0042] In some embodiments, the upper coupler 107 includes an upper housing 109 and an upper grounding terminal 110 and a plurality of upper wiring terminals 111 fixedly disposed on the upper housing 109. The lower coupler 108 is used for plugging and connecting with the upper coupler 107. The lower coupler 108 includes a lower housing 112, a lower grounding terminal 113 and a plurality of lower wiring terminals 114 that can slide independently relative to the lower housing 112 along the plugging direction Y of the upper coupler 107 and the lower coupler 108, and a bottom housing 115 that is slidably matched with the lower housing 112 along the plugging direction Y. The upper grounding terminal 110 is used for electrical contact with the lower grounding terminal 113, and the plurality of upper wiring terminals 111 are used for electrical contact with the plurality of lower wiring terminals 114 in a one-to-one correspondence. 0 is greater than the length of the other upper terminals 111 and / or the length of the lower grounding terminal 113 is greater than the length of the other lower terminals 114. The side of the bottom shell 115 facing the lower shell 112 is also provided with abutment 116. The lower grounding terminal 113 is configured to transmit the contact force of the upper grounding terminal 110 to the bottom shell 115 to drive the bottom shell 115 to move toward the side close to the upper coupler 107. During the movement of the bottom shell 115, the abutment 116 can drive the lower terminals 114 to move upward and contact with the upper terminals 111 accordingly. Figures 1 to 10 In the embodiment shown, the plugging direction Y of the upper coupler 107 and the lower coupler 108 is vertically downward. The cooking cup 102 is detachably assembled to the host 101, and the upper coupler 107 is detachably plugged in up and down through the upper grounding terminal 110 and the lower grounding terminal 113 of the lower coupler 108. In this embodiment, the length of the upper grounding terminal 110 is set to be greater than the length of the other five upper wiring terminals 111, and the length of the lower grounding terminal 113 is set to be greater than the length of the other five lower wiring terminals 114.

[0043] When the cooking cup 102 is assembled on the main unit 101, the upper coupler 107 is inserted downward into the lower coupler 108, and the upper grounding terminal 110 first contacts the lower grounding terminal 113, and then the lower grounding terminal 113 drives the bottom shell 115 to move upward through the contact force of the upper grounding terminal 110. During the upward movement of the bottom shell 115, the abutment 116 is driven to move upward synchronously. The lower terminal 114 moves upward when receiving the upward force of the abutment 116, so that the five upper terminals 111 and the five lower terminals 114 are correspondingly plugged in up and down, realizing the electrical connection between the upper coupler 107 and the lower coupler 108. This arrangement ensures that the coupler assembly 106 is grounded before being energized.

[0044] When the cooking cup 102 is removed from the main unit 101, the upper coupler 107 is separated from the lower coupler 108. At this time, each lower terminal 114 is disconnected from each upper terminal 111 under the action of the abutment 116. At the same time, the abutment 116 pushes the bottom shell 115 to move downward, that is, return to its original position. Since the length of the upper grounding terminal 110 is set to be greater than the length of the other five upper terminals 111, the contact length of the upper grounding terminal 110 and the lower grounding terminal 113 is longer. When the bottom shell 115 returns to its original position downward, the time for the upper grounding terminal 110 to be disconnected from the lower grounding terminal 113 is longer. This arrangement ensures that the coupler assembly 106 is powered off first and then grounded.

[0045] In the above scheme, by lengthening at least one of the upper grounding terminal 110 and the lower grounding terminal 113, the lower grounding terminal 113 is first in contact with the bottom shell 115 relative to each lower wiring terminal 114 and drives the bottom shell 115 to move upward, and the abutment member 116 drives each lower wiring terminal 114 to move upward, so as to contact with each upper wiring terminal 111 of the upper coupler 107, thereby achieving reliable grounding and energization of each wiring terminal, so that when the upper coupler 107 and the lower coupler 108 are plugged in, it is ensured that they are grounded first and then energized, which effectively strengthens the grounding response, improves the safety factor, solves the problem of no response of the grounding wire, and also solves the problem of plastic parts not being energized due to cumulative tolerance.

[0046] exist Figure 3 and Figure 6In the illustrated embodiment, the upper grounding terminal 110 and the plurality of upper wiring terminals 111 extend from the bottom of the upper housing 109, and the length of the upper wiring terminal 111 extending from the bottom of the upper housing 109 is greater than the length of the plurality of upper wiring terminals 111 extending from the bottom of the upper housing 109. The lengths of the plurality of upper wiring terminals 111 are the same. In some embodiments, the dimension L1 of the length of the upper grounding terminal 110 greater than the length of each upper wiring terminal 111 ranges from 1 mm to 2 mm. In some embodiments, the dimension L1 of the length of the upper grounding terminal 110 greater than the length of each upper wiring terminal 111 is 1 mm or 2 mm. Properly setting the length between the upper grounding terminal 110 and each upper wiring terminal 111 helps to increase the sensitivity of the grounding reaction.

[0047] Combination Figures 4 to 8 In the embodiment shown, the bottom shell 115 is provided with a tapered hole 117 which is through along the plugging direction Y and is arranged with a large opening and a small bottom. The lower end of the lower grounding terminal 113 is arranged with a tapered end 118. The tapered end 118 cooperates with the tapered hole 117 under the action of the contact force to drive the bottom shell 115 to move toward the side close to the lower shell 112. In this embodiment, the bottom shell 115 includes a bottom shell body 119 and a bottom shell flange 120 protruding from the surface of the bottom shell body 119. The tapered hole 117 is arranged in the bottom shell flange 120. When the upper coupler 107 and the lower coupler 108 are plugged in and out, the upper grounding terminal 110 first contacts the lower grounding terminal 113, and then the lower grounding terminal 113 is inserted into the tapered hole 117 of the bottom shell 115 through the tapered end 118. At this time, the tapered end 118 and the tapered hole 117 are plugged in and matched with each other. Since the tapered end 118 of the lower grounding terminal 113 and the tapered hole 117 of the bottom shell 115 are matched in taper, the tapered end 118 will exert a downward force on the bottom shell 115, and a reaction force in the opposite direction will be generated on the bottom shell 115. Under the action of the reaction force, the bottom shell 115 moves upward as a whole. In this way, the tapered end 118 of the lower grounding terminal 113 and the tapered hole 117 of the bottom shell 115 are slidably matched, so that the bottom shell 115 moves upward. The driving method is simple, and the positioning and center alignment can be automatically achieved, which is stable and reliable. In this embodiment, the cross-section of the tapered end 118 is a quadrilateral, and the tapered hole 117 is a square tapered hole. In this embodiment, the tapered end 118 with a quadrilateral cross-section is plugged into the square tapered hole, which can be quickly positioned, has high assembly accuracy, is not easy to be misaligned, and is stable and reliable.

[0048] Combination Figure 4 and Figure 7In the illustrated embodiment, the lower grounding terminal 113 includes a grounding terminal body 121 and a grounding insulator 122 connected to the grounding terminal body 121. The grounding insulator 122 is used to fix the upper grounding terminal body 121. The grounding terminal body 121 is used to connect the grounding terminal. Each lower wiring terminal 114 includes a wiring terminal body 123 and a wiring insulator 124 connected to the wiring terminal body 123. The wiring insulator 124 is used to fix the upper wiring terminal body 123. The wiring terminal body 123 is used to connect the power supply end. The grounding terminal body 121 is the same length as each wiring terminal body 123. The length of the grounding insulator 122 is greater than the length of each wiring insulator 124, and the grounding insulator 122 is provided with a tapered end 118. In this embodiment, the length of the grounding insulator 122 is set to be greater than the length of each wiring insulator 124, to ensure that when the upper coupler 107 is plugged into the lower coupler 108, the lower grounding terminal 113 is more likely to contact the bottom shell 115 first than the lower wiring terminals 114, effectively driving the bottom shell 115 to move upward, driving the lower wiring terminals 114 to move upward, and achieving corresponding contact between the lower wiring terminals 114 and the upper wiring terminals 111, thereby effectively improving the power-on response rate.

[0049] exist Figure 4-Figure 5 , Figure 7 In the embodiment shown, the bottom end surfaces of the wiring insulators 124 are arranged flush, and the bottom end surfaces of the grounding insulators 122 are arranged lower than the bottom end surfaces of the wiring insulators 124. The bottom end surfaces of the grounding insulators 122 are arranged lower than the bottom end surfaces of the wiring insulators 124, so that the lower grounding terminal 113 is easier to contact the bottom shell 115 than the wiring terminals, which is conducive to driving the bottom shell 115 to move upward, and the structure and driving method are simple. In some embodiments, the length of the grounding insulator 122 is greater than the length of the wiring insulators 124, and the dimension L2 ranges from 3mm to 6mm (such as Figure 6 ). Figure 6 In the embodiment shown, the length of the ground insulator 122 is greater than the length of each wiring insulator 124 by a dimension L2 of 3 mm, 4 mm, 5 mm, or 6 mm. Properly setting the length between the ground insulator 122 and each wiring insulator 124 can effectively offset the cumulative assembly error, increase the power-on response rate, and improve safety.

[0050] exist Figure 6 to Figure 7In the illustrated embodiment, the number of the upper grounding terminal 110 is set to one, and the number of the upper wiring terminals 111 is set to five. Five upper wiring terminals 111 are arranged on the circumference of the upper grounding terminal 110. The number of the lower grounding terminal 113 is set to one, and the number of the lower wiring terminals 114 is set to five. The length of each wiring insulator 124 is reduced by 3mm-6mm relative to the length of the grounding insulator 122, and the upper and lower movable space of the upper wiring terminal 111 and the lower grounding terminal 113 can also be increased. When the upper coupler 107 and the lower coupler 108 are matched with each other, the bottom shell 115 uses the abutment 116 to move each lower wiring terminal 114 upward by 3mm-6mm as a whole because the tapered end 118 of the lower grounding terminal 113 and the tapered hole 117 of the bottom shell 115 are matched with each other. The advantage of such a setting is that when the plastic parts of the cooking cup 102 or the host 1091 are deformed and shrunk, the resulting overall assembly error can effectively offset the assembly cumulative error, and the power-on response rate is higher. Five lower wiring terminals 114 are arranged on the peripheral side of the lower grounding terminal 113. The number is not limited in this application. The overall height of the lower grounding terminal 113 is 2 mm higher than the height of the other five lower wiring terminals 114, so that the lower grounding terminal 113 is more tightly fitted, and the lower grounding terminal 113 contacts earlier and more deeply than the other five lower wiring terminals 114, effectively performing grounding signal judgment, and having a higher grounding safety factor.

[0051] Combination Figures 4 to 8 In the illustrated embodiment, the bottom shell 115 is provided with a plurality of through holes 125 extending through the plug-in direction Y, and the bottom of each wiring insulator 124 is correspondingly plugged into the plurality of through holes 125 in the plug-in direction Y. In this embodiment, the plurality of through holes 125 are formed in the bottom shell body 119. When the upper coupler 107 is plugged into the lower coupler 108, the upper grounding terminal 110 first contacts the lower grounding terminal 113, and then the lower grounding terminal 113 is inserted into the tapered hole 117 of the bottom shell 115 through the tapered end 118. At this time, the tapered end 118 is plugged into the tapered hole 117 with a gap, and the tapered end 118 exerts a downward force on the bottom shell 115, and a reaction force in the opposite direction is generated on the bottom shell 115, and the bottom shell 115 moves upward under the action of the reaction force. When the bottom shell 115 moves upward, it drives the abutment 116 to move upward. When the lower terminal 114 is subjected to the upward force of the abutment 116, it moves upward. The bottom of the wiring insulator 124 of the lower terminal 114 is plugged into and matched with the plurality of through holes 125 in the plug-in direction Y. The plug-in matching method is simple and fast, and is convenient for disassembly or installation and easy to operate.

[0052] Combination Figures 4 to 7 and Fig.10In the illustrated embodiment, a grounding positioning surface 126 is formed on the grounding insulator 122, and the grounding positioning surface 126 abuts against the top of the bottom shell flange 120. In the plug-in direction Y, the grounding positioning surface 126 where the bottom of the grounding insulator 122 is plugged in with the tapered hole 117 is higher than the wiring positioning surface where each wiring insulator 124 is plugged in with the plurality of through holes 125. The wiring positioning surfaces where each wiring insulator 124 is plugged in with the plurality of through holes 125 are at the same height. Setting the grounding positioning surface 126 higher than the wiring positioning surface allows the lower grounding terminal 113 to contact the bottom shell 115 earlier and more deeply than each lower wiring terminal 114, and to more effectively determine the grounding signal, resulting in a higher safety factor. In some embodiments, the dimension L3 of the grounding positioning surface 126 that is higher than each wiring positioning surface ranges from 1mm to 2mm (e.g. Figure 6 or Fig.10 In some embodiments, the grounding positioning surface 126 is higher than each wiring positioning surface by a dimension L3 of 1 mm or 2 mm. The grounding positioning surface 126 and the wiring positioning surface are appropriately set at a high level, and the tapered end 118 and the tapered hole 117 are effectively slidably matched, thereby effectively improving the grounding response rate.

[0053] exist Figure 3 , Figure 4 , Figure 7 and Fig. 9In the illustrated embodiment, the abutment member 116 includes a spring sheet 127. The spring sheet 127 has a simple structure, is light in weight and has low cost. In the present embodiment, the spring sheet 127 is in a V-shaped structure, one side of the V-shaped structure is connected to the bottom shell 115, and the other side is used to abut against the lower terminal 114, and the mouth of the V-shaped structure faces the edge of the bottom shell 115. The abutment member 116 is set as the spring sheet 127, which has a simple structure and low assembly cost. In the present embodiment, the spring sheet 127 is elastic and is arranged on the surface of the bottom shell body 119. When the cooking cup 102 is assembled to the main unit 101, the upper coupler 107 is plugged into the lower coupler 108, and the upper grounding terminal 110 first contacts the lower grounding terminal 113, and then the lower grounding terminal 113 is inserted into the tapered hole 117 of the bottom shell 115 through the tapered end 118. At this time, the tapered end 118 and the tapered hole 117 are plugged and matched with each other. The tapered end 118 will exert a downward force on the bottom shell 115, and a reaction force in the opposite direction will be generated on the bottom shell 115. The bottom shell 115 moves upward under the action of the reaction force. When the bottom shell 115 moves upward, it drives the spring 127 to move upward. At this time, the top of the spring 127 abuts against the bottom of the wiring insulator 124 of the lower wiring terminal 114, and the bottom shell 115 slowly moves upward under the elastic action of the spring 127. When the cooking cup 102 is removed from the main unit 101, the upper coupler 107 is separated from the lower coupler 108. At this time, each lower terminal 114 is first disconnected from each upper terminal 111 under the action of the spring 127. At the same time, the bottom shell 115 moves downward under the action of the spring 127, that is, returns to its original position. When the bottom shell 115 returns to its original position, the upper grounding terminal 110 is disconnected from the lower grounding terminal 113 for a longer time. This arrangement ensures that the coupler assembly 106 is powered off first and then grounded. In the above process, the elasticity and recoverability of the spring 127 can be used to effectively control the upper coupler 107 and the lower coupler 108 in a non-contact state, so that the bottom shell 115 returns to its original position, and the safety factor is higher when the food processor 1 is not started.

[0054] exist Figures 7 to 9In the illustrated embodiment, the spring 127 includes a first spring branch 128 and a second spring branch 129, and the first spring branch 128 and the second spring branch 129 are located on the peripheral side of the through hole 125. In the present embodiment, the spring 127 is in a double V-shaped structure. The wiring insulator 124 of the lower wiring terminal 114 is subjected to the force of the first spring branch 128 and the second spring branch 129, so that the movement process of each lower wiring terminal 114 driven by the first spring branch 128 and the second spring branch 129 is stable and reliable. In some embodiments, the number of springs 127 is set to multiple, and multiple springs 127 are correspondingly arranged for each lower wiring terminal 114. In the present embodiment, the number of each lower wiring terminal 114 is set to five, and the number of springs 127 can be set to five. By providing multiple springs 127 and correspondingly arranging multiple springs 127 with each lower wiring terminal 114, the force of each lower wiring terminal 114 subjected to the spring 127 is balanced, so that the movement process of each lower wiring terminal 114 driven by the spring 127 is stable and reliable.

[0055] exist Figure 7 In the illustrated embodiment, the lower coupler 108 further includes a lower housing top cover 130 and a waterproof seal 131. The lower housing top cover 130 is disposed on the top of the lower housing 112, and the waterproof seal 131 is disposed between the lower housing 112 and the lower housing top cover 130. The lower housing top cover 130 is used to cover the lower housing 112, and the waterproof seal 131 plays a waterproof sealing role.

[0056] In the above scheme, when the upper coupler 107 and the lower coupler 108 are not mated with each other, the spring 127 will pop open the bottom shell 115 of the lower coupler 108, so that the bottom shell 115 returns to its original state. When the upper coupler 107 and the lower coupler 108 are mated with each other, the bottom shell 115 will slide up all the terminals provided on the lower coupler by 3mm-6mm due to the sliding fit between the tapered end 118 of the lower grounding terminal 113 and the tapered hole 117 provided on the bottom shell flange 120. In this way, when the plastic parts of the cooking cup 102 or the host 1091 are deformed and shrunk, the resulting overall assembly error can effectively offset the cumulative assembly error, and the power-on response rate is higher. The overall height of the lower grounding terminal 113 is 2mm higher than the height of the other five lower wiring terminals 114, so that the lower grounding terminal 113 is more tightly matched, and the lower grounding terminal 113 contacts earlier and more deeply than the other five lower wiring terminals 114, effectively performing grounding signal judgment, and having higher safety.
