Food processor

Abstract

The application discloses a food processor. The food processor comprises a cup body assembly, a cup cover assembly and a main machine. The main machine comprises a main machine coupler. The cup body assembly comprises a cup body coupler and a safety switch which are separately arranged and electrically connected. When the cup cover assembly is combined with the cup body assembly, the cup cover assembly abuts against a connecting rod, so that the connecting rod triggers the safety switch to be closed. When the cup body assembly and the cup cover assembly are placed in the main machine, the cup body coupler is in communication with the main machine coupler. In the food processor, the main machine does not need to be provided with a connecting rod insertion hole through which the connecting rod passes, so that water or other liquids can be prevented from entering the interior of the main machine, and in turn, the risk of damage of electrical devices in the main machine or circuit short circuit can be avoided.

Description

Technical Field

[0001] This application relates to household appliances, and in particular to food processors. Background Technology

[0002] The blender includes a main unit, a cup assembly, and a lid assembly. The main unit comprises a housing, a motor, and a safety switch (usually a microswitch). The motor and safety switch are located inside the housing and connected to it. The housing also has a connecting rod insertion hole that connects the interior of the housing to the exterior of the blender. The cup assembly includes a connecting rod.

[0003] The cup lid assembly and cup body assembly are fully engaged, and the cup lid assembly and cup body assembly are placed behind the main unit, with the cup lid assembly abutting against the connecting rod. The connecting rod is inserted into the main unit through the connecting rod socket and abuts against the safety switch. Thus, the main unit determines that the cup lid assembly is fully engaged, and the motor starts to work.

[0004] In the aforementioned food processors, liquids such as water may enter the main unit through the connecting rod socket, potentially causing damage to internal electrical components and / or short circuits. Utility Model Content

[0005] The purpose of this application is to disclose a food processor. This food processor helps avoid risks such as damage to electrical components and / or short circuits.

[0006] This application discloses a food processor. The food processor includes a cup body assembly, a lid assembly, and a main unit. The main unit includes a main unit coupler. The cup body assembly includes a cup body coupler, a safety switch, and a connecting rod. The cup body coupler and the safety switch are separately disposed and electrically connected through a connector. When the lid assembly is closed to the cup body assembly, the lid assembly abuts against the connecting rod, causing the connecting rod to trigger the safety switch to close. When the cup body assembly and the lid assembly are placed together on the main unit, the cup body coupler is connected to the main unit coupler.

[0007] As described above, because the cup assembly includes a cup coupler, a safety switch, and a connecting rod, the cup lid assembly closes to the cup body assembly, causing the cup lid assembly to abut against the connecting rod, which triggers the safety switch to close. When the cup lid assembly and the cup body assembly are placed together on the main unit, the main unit coupler and the cup coupler are connected to transmit signals, so that the control board of the food processor can determine that the cup lid assembly and the cup body assembly are properly closed. In this way, the safety switch is not located on the main unit, and the connecting rod socket is not required on the main unit. Therefore, the above configuration helps to prevent liquids such as water from entering the interior of the main unit, and helps to avoid the risk of damage to electrical components and / or short circuits in the main unit.

[0008] In some embodiments, the cup assembly includes a cup body. The connecting rod is located on the side of the cup body and includes an abutting end that abuts against the cup lid assembly and a triggering end that triggers the safety switch. The triggering end includes an abutting surface and a limiting surface connected to the abutting surface. The limiting surface extends along the height direction of the cup body and radially limits the safety switch. The abutting surface is located below the limiting surface. When the cup lid assembly and the cup body assembly are in place, the connecting rod moves downward, causing the abutting surface to push the contact of the safety switch in a direction perpendicular to the connecting rod, thereby triggering the safety switch to close.

[0009] As described above, since the contact surface pushes the contact of the safety switch to move in a direction perpendicular to the connecting rod to trigger the safety switch to close, and the limiting surface laterally limits the safety switch, the contact can only exert force on the connecting rod in a direction perpendicular to the connecting rod, and will not exert an upward force on the connecting rod, so that the connecting rod will not move upward. Therefore, the above configuration can ensure that the connecting rod and the contact reliably abut, thereby ensuring that the contact of the safety switch can reliably abut with the connecting rod when the cup lid assembly and the cup body assembly are closed, thus improving reliability.

[0010] In some embodiments, the contact surface is an arc surface or a slope.

[0011] As described above, the contact surface is either curved or inclined. Both curved and inclined surfaces have a certain slope, making it easier to push the contact point to move and making the safety switch triggering more reliable.

[0012] In some embodiments, the cup assembly includes a switch bracket for mounting the safety switch, the switch bracket including a bracket top plate with a connecting rod insertion hole; the connecting rod passes through the connecting rod insertion hole, and a reset element is provided between the connecting rod and the bracket top plate.

[0013] As described above, the top plate of the switch bracket abuts against the reset component. On one hand, the proximity of the reset component to the contact point improves the precision of the engagement between the connecting rod and the safety switch contacts. On the other hand, by using the top plate of the switch bracket as the abutment against the reset component, and with the connecting rod insertion hole on the top plate, no additional abutment structure is needed, nor is an abutment structure required on the handle. This reduces the number of parts in the food processor and simplifies its structure. Furthermore, since the connecting rod insertion hole is located on the switch bracket, and the safety switch is also mounted on the switch bracket, both the structure that engages with the connecting rod and the structure for mounting the safety switch are based on the switch bracket, resulting in smaller dimensional chain errors and higher precision in the engagement between the connecting rod and the safety switch contacts. Moreover, the connecting rod insertion hole can also position and guide the movement of the lower section of the connecting rod, eliminating the need for a separate structure for positioning and guiding the lower section of the connecting rod, further reducing the number of parts in the food processor and simplifying its structure.

[0014] In some embodiments, the cup assembly includes a cup holder and a switch bracket for mounting the safety switch; both the switch bracket and the cup coupler are located within the cup holder, the cup holder includes a cup holder bottom cover and a limiting portion, and both the safety switch and the switch bracket are limited between the limiting portion and the cup holder bottom cover.

[0015] As described above, the safety switch can be installed on the switch bracket to form a whole. Then, the switch bracket is inserted into the bottom cover of the cup holder, and the bottom cover of the cup holder is assembled with the bottom of the cup holder so that both the switch bracket and the cup body coupler abut against the abutting part. Thus, the cup body coupler and the switch bracket are limited and fixed in multiple directions (up, down, front, back, left, and right). During the operation of the food processor, the cup body coupler and the switch bracket are not easy to loosen, and the connection between the cup body coupler and the switch bracket is reliable.

[0016] In some embodiments, the limiting portion is stepped and includes a first limiting portion, a second limiting portion, and a connecting portion connecting the two. The height of the first limiting portion is lower than the height of the second limiting portion. The cup body coupler is limited between the first limiting portion and the bottom cover of the cup seat, and the safety switch is limited between the second limiting portion and the bottom cover of the cup seat.

[0017] As described above, since the cup body coupler is limited between the first limiting part and the bottom cover of the cup holder, and the safety switch is limited between the second limiting part and the bottom cover of the cup holder, the cup body coupler and the safety switch can be reliably limited and are not easy to loosen.

[0018] In some embodiments, the cup holder bottom cover includes opposing posts, each post including a slot extending along the height direction of the cup body assembly; the opposite sides of the switch bracket are inserted into the slots one-to-one.

[0019] As described above, the opposite sides of the switch bracket are inserted into the slots one by one. On the one hand, this facilitates the assembly of the switch bracket and the bottom cover of the cup holder. On the other hand, it makes the switch bracket less prone to loosening. In addition, the switch bracket abuts against the abutting part, limiting the multiple directions (up, down, front, back, left, and right) of the switch bracket, making it less prone to loosening. Consequently, the safety switch is less likely to loosen, and the connecting parts will not be pulled. The connection between the safety switch and the cup body coupler is reliable.

[0020] In some embodiments, the cup holder bottom cover includes a coupler mounting groove, the peripheral wall of which abuts against the peripheral wall of the cup body coupler, and the bottom wall of the coupler mounting groove supports the cup body coupler.

[0021] As described above, the peripheral wall of the coupler mounting slot abuts against the peripheral wall of the cup coupler, and the bottom wall of the coupler mounting slot supports the cup coupler. Thus, the cup coupler can be installed simply by inserting it into the coupler mounting slot, making installation convenient. Furthermore, with the abutting part abutting against the cup coupler, the cup coupler is limited in its circumference, top, and bottom, making it less prone to loosening and ensuring a reliable connection between the cup coupler and the safety switch.

[0022] In some embodiments, the cup assembly includes a switch bracket for mounting the safety switch, the switch bracket and the safety switch being mounted via a snap-fit ​​structure; the switch bracket and the safety switch are also positioned via a positioning structure, and the switch bracket and the safety switch are plugged into each other via the positioning structure.

[0023] As described above, the safety switch is first positioned by inserting it into the switch bracket using the positioning structure, and then the safety switch is pressed down along the bracket base perpendicular to the switch bracket. This facilitates the assembly of the safety switch. Furthermore, the circumferentially distributed snap-fit ​​structure restricts the movement of the safety switch perpendicular to the bracket base, and the positioning structure restricts its movement parallel to the bracket base. Thus, the safety switch is fixed in multiple directions (front, back, left, right, up, down), preventing loosening and ensuring a reliable connection between the safety switch and the cup coupler.

[0024] In some embodiments, the switch bracket includes a bracket base and a snap-fit ​​arm protruding from the bracket base; the safety switch is assembled on the bracket base and includes a switch surface opposite to the bracket base; the snap-fit ​​structure includes the snap-fit ​​arm, which snaps onto the switch surface.

[0025] As described above, the snap-fit ​​structure includes the snap-fit ​​arm and the switch surface, with the switch surface facing away from the bracket substrate. In this way, when the safety switch is pressed down until it contacts the bracket substrate, the snap-fit ​​arm and the switch surface are engaged, making the safety switch easy to assemble.

[0026] In some embodiments, the positioning structure includes a plurality of positioning holes passing through the safety switch and positioning posts disposed on the switch bracket; the positioning posts pass through the positioning holes one by one.

[0027] As described above, since the positioning hole is a through hole, the positioning post can be seen through the through hole, which facilitates the insertion of the positioning hole and the positioning post. In addition, there are multiple positioning holes and positioning posts. The positioning hole and the positioning post cooperate to prevent the safety switch from rotating, thus making it easier to achieve the interlocking of the safety switch and the switch bracket.

[0041] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0043] See Figures 1 to 3 , Figure 5 , Figure 6 and Figure 9 This application discloses a food processor. The food processor includes a cup body assembly 10, a cup lid assembly 20, and a main unit 30. See also... Figure 2 , Figure 5 , Figure 9 and Figure 10 The main unit 30 includes a main unit coupler 301. The cup body assembly 10 includes a cup body coupler 1, a safety switch 2, a connecting rod 3, and a cup body 101. The cup body 101 is fitted onto the cup lid assembly 20. The cup body coupler 1 and the safety switch 2 are separate components, meaning they are two independent parts. See also... Figures 3 to 6 The cup coupler 1 is electrically connected to the safety switch 2. The method of electrical connection is not limited; for example, the cup coupler 1 and the safety switch 2 can be electrically connected via a connector 4. The connector 4 can be a wire, metal sheet, etc., as long as it enables the transmission of electrical signals.

[0044] See Figures 9 to 12When the lid assembly 20 and the cup body assembly 10 are fully closed, the lid assembly 20 abuts against the connecting rod 3, causing the connecting rod 3 to trigger the safety switch 2 to close. When the cup body assembly 10 and the lid assembly 20 (i.e., the lid assembly 20 and the cup body assembly 10 are assembled as a whole) are placed on the main unit 30, the cup body coupler 1 is connected to the main unit coupler 301, realizing the circuit connection of the food processor. In this application, the cup body assembly 10 and the lid assembly 20 constitute a blending cup assembly, which has a locked state and an open state. The fully closed state means that the lid assembly 20 and the cup body assembly 10 are in the locked state. As long as the cup body assembly 10 and the lid assembly 20 are placed on the main unit 30, the food processor can work when powered on. In the open state, the user can pour out the food in the cup body assembly 10, or clean the inside of the cup body assembly 10, or, if the blending blade assembly inside the cup body assembly 10 is detachable, the user can remove the blending blade assembly for cleaning. The lid assembly 20 can adopt any structure to abut the connecting rod 3, as long as the connecting rod 3 moves and ultimately closes the safety switch 2. After the main unit coupler 301 and the cup body coupler 1 are connected, when the lid assembly 20 and the cup body assembly 10 are in place, the circuit of the food processor is connected, thereby activating the relevant functions of the food processor. For example, starting the motor, the control board will control the motor to drive the mixing blade assembly to mix the food in the cup body assembly 10; or activating the heating function, the control board will heat the food in the cup body assembly 10. The location of the motor and control board within the main unit 30, cup body assembly 10, and lid assembly 20 is not limited, as long as the control board can control the motor to achieve the functions of the food processor. For example, the motor can be located in the cup body assembly 10, and the control board can be located inside the main unit 30.

[0045] See Figure 13 In related technologies, the main unit 30 is provided with a connecting rod insertion hole 71 for inserting the connecting rod 3. When the cup lid assembly 20 and the cup body assembly 10 are placed together on the main unit 30, after the cup lid assembly 20 and the cup body assembly 10 are closed, the connecting rod 3 is inserted into the connecting rod insertion hole 71 to trigger the safety switch 2 inside the main unit 30, and the cup lid assembly 20 and the cup body assembly 10 are closed. However, when the stirring cup assembly (the cup body assembly 10 and the cup lid assembly 20 as a whole) is not placed on the main unit 30, liquids such as water may flow into the main unit 30 from the connecting rod insertion hole 71, causing damage to the electrical components inside the main unit 30, and / or, risks such as short circuits.

[0046] Based on the above configuration, since the cup assembly 10 includes a cup coupler 1, a safety switch 2, and a connecting rod 3, when the cup lid assembly 20 is closed to the cup assembly 10, the cup lid assembly abuts against the connecting rod, causing the connecting rod 3 to trigger the safety switch 2 to close. When the cup lid assembly 20 and the cup assembly 10 are placed together on the main unit 30, the main unit coupler 301 communicates with the cup coupler 1 to transmit a signal, so that the control board of the food processor can determine that the cup lid assembly 20 and the cup assembly 10 are closed. In this way, the safety switch 2 is not provided on the main unit 30, and the connecting rod insertion hole 71 is not provided on the main unit 30. Therefore, the above configuration helps to prevent liquids such as water from entering the interior of the main unit 30, and helps to prevent damage to electrical components inside the main unit 30, and / or the risk of short circuits.

[0047] Furthermore, the cup coupler 1 and the safety switch 2 are separate units that are electrically connected. Compared with some cup couplers 1 and safety switches 2 that are integrated, both the safety switch 2 and the cup coupler 1 can be standard parts, which are easy to manufacture. They also include protective structures such as housings. Based on the protection of these protective structures, they are not prone to generating sparks and there is no safety hazard.

[0048] Finally, in the aforementioned integrated structure, the safety switch 2 includes a moving contact and a stationary contact, each connected to an electrode of the cup coupler. This can lead to poor contact between the stationary and moving contacts due to insufficient elasticity, resulting in low reliability of the connection between the safety switch and the cup coupler. However, this application uses a separate cup coupler 1 and safety switch 2, with the safety switch 2 electrically connected to the cup coupler 1. This eliminates the problem of low connection reliability caused by poor contact between the moving and stationary contacts, thus ensuring stable and reliable performance of the food processor.

[0049] See Figure 11 and Figure 12 The cup assembly includes a cup body 101. The connecting rod 3 is located on the side of the cup body 101. The connecting rod includes an abutting end that abuts against the cup lid assembly and a triggering end 33 that triggers the safety switch 2. The triggering end 33 includes an abutting surface 31 and a limiting surface 32 connected to the abutting surface 31. The limiting surface 32 extends along the height direction of the cup body 101 and radially limits the safety switch 2. The abutting surface 31 is located below the limiting surface 32. In some embodiments, the abutting surface 31 and the limiting surface 32 form an obtuse angle. During the process of the cup lid assembly 20 and the cup body assembly 10 closing, the abutting surface 31 of the connecting rod 3 contacts the contact point 21 of the safety switch 2. As the cup lid assembly 20 continues to close, the connecting rod 3 continues to move downwards, causing the abutting surface 31 to push the contact point 21 to move radially along the cup body assembly 10 (which can also be understood as moving in a direction perpendicular to the connecting rod 3, such as retracting into the cup body assembly 10). Figure 11 and Figure 12 (As indicated by the middle arrow R), ultimately, the safety switch 2 is triggered to close. The cup lid assembly 20 can push the linkage 3 to move through any structure, so that the abutment surface 31 of the linkage 3 can contact the contact point 21, for example, see... Figure 6 The top of the connecting rod 3 includes a top inclined surface 391 and a connecting rod top surface 392 connected to the top inclined surface 391. See also Figure 8 The cup lid assembly 20 includes a cup lid inclined surface 201 and a cup lid abutting surface 202. The cup lid inclined surface 201 cooperates with the top inclined surface 391 to push the connecting rod 3 downward, thereby causing the abutting surface 31 to push the contact point 21 inward along the radial direction (perpendicular to the connecting rod 3) of the cup body assembly. When the cup lid assembly 20 is closed, the top surface 392 of the connecting rod abuts against the cup lid abutting surface 202. The limiting surface 32 forms an obtuse angle with the abutting surface 31. The limiting surface 32 is perpendicular to the movement direction of the contact point 21 of the safety switch 2. For example, if the cup body assembly 10 includes a cup body 101, the limiting surface 32 is parallel to the axis of the cup body 101, that is, the limiting surface 32 is parallel to the vertical plane, and the contact point 21 moves radially along the cup body 101. When the cup lid assembly 20 and the cup body assembly 10 are closed, the limiting surface 32 abuts against the contact point 21.

[0050] As described above, since the contact surface 31 pushes the contact 21 of the safety switch 2 to move radially along the cup body 101, that is, to move in a direction perpendicular to the connecting rod 3, thereby triggering the safety switch 2 to close, and the limiting surface 32 limits the safety switch 2 radially, the contact 21 can only exert force on the connecting rod 3 in a direction perpendicular to the connecting rod 3, and will not exert an upward force on the connecting rod 3, thus preventing the connecting rod 3 from moving upward. Therefore, the above configuration can ensure that the connecting rod 3 and the contact 21 reliably abut, thereby ensuring that the contact 21 of the safety switch 2 can reliably abut with the connecting rod 3 when the cup lid assembly 20 and the cup body assembly 10 are closed, improving reliability.

[0051] In some embodiments, the abutment surface 31 is an arc surface or an inclined surface. When the abutment surface 31 is an arc surface, the obtuse angle is the angle between the tangent of the arc surface and the limiting surface.

[0052] As described above, the contact surface 31 is an arc surface or an inclined surface. Both the inclined surface and the arc surface have a certain slope, which makes it easier to push the contact point to move and makes the triggering of the safety switch 2 more reliable.

[0053] See Figure 4 , Figure 6 and Figure 12The cup assembly 10 includes a switch bracket 7 for mounting the safety switch 2. The switch bracket 7 includes a bracket top plate 73 with the connecting rod insertion hole 71. In some embodiments, the switch bracket 7 includes a bracket base plate 72 and a bracket top plate 73 perpendicular to the bracket base plate 72. The bracket top plate 73 has the connecting rod insertion hole 71. The connecting rod 3 passes through the connecting rod insertion hole 71. The cup assembly includes a reset member 8, with both ends of the reset member 8 abutting against the connecting rod 3 and the bracket top plate 73 respectively (i.e., a reset member 8 is provided between the connecting rod 3 and the bracket top plate 73). Thus, when the cup lid assembly 20 is closed, the cup lid assembly 20 pushes the connecting rod 3 downwards, and the connecting rod 3 compresses the reset member 8. During the transition of the cup lid assembly from the closed state to the open state, the reset member 8 applies a spring force to the connecting rod 3, causing the connecting rod 3 to reset.

[0054] As described above, the top plate 73 of the switch bracket 7 is used to abut against the reset member 8. On the one hand, the reset member 8 is closer to the contact 21, which facilitates a higher precision in the engagement between the connecting rod 3 and the contact 21 of the safety switch 2. On the other hand, by using the top plate 73 of the switch bracket 7 as the component that abuts against the reset member 8, and by providing the connecting rod insertion hole 71 on the top plate 73, no additional abutment structure is needed, nor is an abutment structure required on the handle. This results in fewer parts and a simpler structure for the food processor. Furthermore, since the connecting rod insertion hole 71 is provided on the switch bracket 7, and the safety switch 2 is also mounted on the switch bracket 7, both the structure that engages with the connecting rod 3 and the structure for mounting the safety switch 2 are based on the switch bracket 7, resulting in smaller dimensional chain errors and a higher precision in the engagement between the connecting rod 3 and the contact 21 of the safety switch 2. Furthermore, the connecting rod socket 71 can also position and guide the movement of the lower section of the connecting rod 3, eliminating the need to design a structure for positioning and guiding the lower section of the connecting rod 3, which also reduces the number of parts in the food processor and simplifies its structure.

[0055] See Figure 2 , Figure 3 , Figure 6 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The cup assembly 10 includes a cup holder 5 and a switch bracket 7 for mounting the safety switch 2. Both the switch bracket 7 and the cup coupler 1 are located within the cup holder 5. The cup holder 5 includes a cup holder bottom cover 6 and a limiting part 51. The cup holder 5 includes a cup holder body, and the cup holder bottom cover 6 can be integrally formed with the cup holder body to constitute the cup holder 5, or the cup holder bottom cover 6 can be mounted to the cup holder body via a snap-fit ​​or other mounting structure. In some cases, the cup holder bottom cover 6 contacts the top surface of the main unit 30. See also... Figure 6The limiting part 51 is located above the cup holder bottom cover 6. The safety switch 2 and the switch bracket 7 are both limited between the limiting part 51 and the cup holder bottom cover 6. One embodiment of the limiting is through direct contact, more specifically as follows: the switch bracket 7 and the cup body coupler 1 are both assembled with the cup holder bottom cover 6 and in direct contact, and both abut against the limiting part 51 and in direct contact.

[0056] As described above, the safety switch 2 can be installed on the switch bracket 7 to form a whole. Then, the switch bracket 7 is inserted into the bottom cover 6 of the cup holder, and the bottom cover 6 of the cup holder is assembled with the bottom of the cup holder 5 to make the switch bracket 7 abut against the cup body coupler 1. Thus, the cup body coupler 1 and the switch bracket 7 are limited and fixed in multiple directions (up, down, front, back, left and right). During the operation of the food processor, the cup body coupler 1 and the switch bracket 7 are not easy to loosen, and the connection between the cup body coupler 1 and the switch bracket 7 is reliable.

[0057] See Figure 6 The limiting part 51 is stepped and includes a first limiting part 511, a second limiting part 512, and a connecting part 513 connecting the two. The height of the first limiting part 511 is lower than the height of the second limiting part 512. The cup body coupler 1 is limited between the first limiting part 511 and the cup base cover 6, and the safety switch 2 is limited between the second limiting part 512 and the cup base cover 6. The structure of the first limiting part 511 and the second limiting part 512 is not limited, as long as they can abut against the cup body coupler 1 and the safety switch 2 respectively. The safety switch 2 being limited between the second limiting part 512 and the cup base cover 6 includes: 1) the second limiting part 512 abutting against the safety switch 2; 2) because the safety switch 2 is mounted on the switch bracket 7, the second limiting part 512 abutting against the switch bracket 7.

[0058] As described above, since the cup body coupler 1 is limited between the first limiting part 511 and the cup base cover 6, and the safety switch 2 is limited between the second limiting part 512 and the cup base cover 6, the cup body coupler 1 and the safety switch 2 can be reliably limited and are not easy to loosen.

[0059] See Figure 7 , Figure 10 and Figure 12 The cup base cover 6 includes opposing inserts 61. Each insert 61 includes a slot 611 extending along the height direction of the cup body assembly 10. In one embodiment, the height direction of the cup body assembly 10 is vertical, which can also be understood as the direction of the rotation center line of the stirring blade assembly within the cup body assembly 10. The slot 611 is U-shaped. See also Figure 12The opposite sides of the switch bracket 7 are inserted into the slots 611 one by one. However, the slots 611 are not limited to a U-shape; they can be inserted as long as they are compatible with the shape of the side of the switch bracket 7.

[0060] As described above, the opposite sides of the switch bracket 7 are inserted into the slots 611 one by one. On the one hand, this facilitates the assembly of the switch bracket 7 with the cup base cover 6. On the other hand, it makes the switch bracket 7 less prone to loosening. In addition, the switch bracket 7 abuts against the limiting part 51, limiting the multiple directions (up, down, front, back, left, and right) of the switch bracket 7. The switch bracket 7 is not prone to loosening. Consequently, the safety switch 2 is not prone to loosening, and therefore will not pull the connecting piece 4. The safety switch 2 is reliably connected to the cup body coupler 1.

[0061] See Figure 7 and Figure 4 The cup holder bottom cover 6 includes a coupler mounting groove 62. The peripheral wall of the coupler mounting groove 62 abuts against the peripheral wall of the cup body coupler 1. In this embodiment, the circumferential shape of the coupler mounting groove 62 is the same as the circumferential shape of the cup body coupler 1 to achieve the abutment. For example, both are approximately square to achieve the abutment. Of course, the abutment can be a locking mechanism, as long as the cup body coupler 1 will not loosen circumferentially. The bottom wall of the coupler mounting groove 62 supports the cup body coupler 1. The method of support is not limited; for example, see [reference needed]. Figure 7 In some embodiments, the coupler mounting slot 62 is a through slot; however, the bottom wall of the coupler mounting slot 62 includes a ring of bosses 621, which support the cup-shaped coupler 1, thus enabling the bottom wall to support the cup-shaped coupler 1. In other embodiments, the coupler mounting slot 62 is not a through slot; in this case, the bottom wall of the coupler mounting slot 62 supports the cup-shaped coupler 1.

[0062] As described above, the peripheral wall of the coupler mounting groove 62 abuts against the peripheral wall of the cup coupler 1, and the bottom wall of the coupler mounting groove 62 supports the cup coupler 1. In this way, it is convenient to insert the cup coupler 1 into the coupler mounting groove 62. Furthermore, combined with the limiting part 51 abutting against the cup coupler 1, the cup coupler 1 is limited in the circumference, top, and bottom, making it less prone to loosening and ensuring a reliable connection between the cup coupler 1 and the safety switch 2.

[0063] See Figure 4 , Figure 5 and Figure 12The cup assembly includes a switch bracket 7 for mounting the safety switch 2. The switch bracket 7 and the safety switch 2 are mounted via a snap-fit ​​structure 91. The snap-fit ​​structures 91 can be distributed circumferentially on the switch bracket 7. In the case of two snap-fit ​​structures 91, the two snap-fit ​​structures 91 are distributed at 180 degrees circumferentially. More specifically, the safety switch 2 is approximately square, and one snap-fit ​​structure 91 is located... Figure 12 In the upper left corner, another latching structure 91 is located in the lower right corner. The switch bracket 7 and the safety switch 2 are also positioned by a positioning structure 92, and the switch bracket 7 and the safety switch 2 are plugged into each other through the positioning structure 92. The positioning structure is not limited, as long as it can achieve plugging.

[0064] As described above, the safety switch 2 is first positioned by inserting it into the switch bracket 7 using the positioning structure 92, and then positioned along the direction perpendicular to the bracket base plate 72 of the switch bracket 7. Figure 4 and Figure 5 The safety switch 2 is pressed down (in the direction of the middle arrow m), thus facilitating its assembly. Furthermore, the circumferentially distributed snap-fit ​​structure 91 restricts the movement of the safety switch 2 perpendicular to the support base plate 72, and the positioning structure restricts its movement parallel to the support base plate 72. Thus, the safety switch 2 is fixed in multiple directions (front, back, left, right, up, down), making it less prone to loosening, and ensuring a reliable connection between the safety switch 2 and the cup coupler 1.

[0065] The structure of the snap-fit ​​structure 91 is not limited, as long as it can enable the safety switch 2 to be snapped into the switch bracket 7. The following describes one snap-fit ​​structure 91.

[0066] See Figure 4 and Figure 5 The switch bracket 7 includes a bracket base plate 72 and a latching arm 74 protruding from the bracket base plate 72. The latching arm 74 is perpendicular to the bracket base plate 72, but is not limited thereto; it only needs to achieve the function of a latching structure. See also Figure 12 The safety switch 2 is located on the support base plate 72 and includes a switch surface 22 opposite to the support base plate 72. The latching structure 91 includes a latching arm 74. The latching arm 74 is latched to the switch surface 22.

[0067] As described above, the snap-fit ​​structure 91 includes the snap-fit ​​arm 74, and the switch surface 22 is opposite to the bracket base plate 72. In this way, the safety switch 2 is pressed down until it contacts the bracket base plate 72, and the snap-fit ​​arm 74 and the switch surface 22 are engaged, so the safety switch 2 and the switch bracket 7 can be assembled. The safety switch 2 is easy to assemble.

[0068] See Figure 4 , Figure 5 , Figure 10 and Figure 12 The positioning structure 92 includes multiple positioning holes 23 passing through the safety switch 2 and positioning posts 75 disposed on the switch bracket 7. The positioning posts 75 pass through the positioning holes 23 one by one.

[0069] As described above, since the positioning hole 23 is a through hole, it is convenient to insert the positioning hole 23 and the positioning post 75. In addition, there are multiple positioning holes 23 and positioning posts 75. The positioning hole 23 and the positioning post 75 cooperate to prevent the safety switch 2 from rotating, and thus, it is easier to achieve the interlocking of the safety switch 2 and the switch bracket 7.
