Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchen appliances, in particular to a food processor. Background Art
[0002] A food processor that is usually mounted on a main unit has a button on the top of the main unit. When in use, the user needs to press the button to trigger a switch in the main unit to start the food processor. For example, patent CN216823033U discloses a food processor main unit, which includes an integrated button and a switch in the main unit housing. When the integrated button is pressed, the switch is triggered to close.
[0003] Specifically, the lower surface of the integrated button is provided with a protrusion, and the top of the switch is provided with a contact, and the protrusion presses against the contact to close the switch. The protrusion is a circular protrusion, and forms a point triggering method with the contact. On the one hand, the position accuracy of the protrusion is required to be high. If there is a deviation in the position of the protrusion and the contact, it is easy to cause trigger failure; on the other hand, the user needs to press the button near or opposite the protrusion to achieve effective triggering, which requires high triggering accuracy and requires the user to accurately position and press, which increases the burden on the user and is not conducive to improving convenience.
[0004] In addition to the above-mentioned structure and triggering method in which the protrusion directly corresponds to the contact, the prior art also has a structure, that is, the switch is provided with a spring sheet above the contact, and when the button is pressed, the protrusion presses down the spring sheet to act on the contact. Since the protrusions in the prior art are mostly circular or square protrusions, the contact area with the spring sheet is small, in order to achieve effective triggering, the position of the protrusion still needs to be strictly controlled. On the contrary, when the protrusion is arranged close to the cantilever end of the spring sheet, it is easy for the protrusion to press down the spring sheet, causing the spring sheet to bulge upward and cause trigger failure, thereby reducing the trigger success rate and being not conducive to improving the reliability of the machine.

[0007] The food processor of the present invention also has the following additional technical features:
[0008] The overlapping length of the plumb line projection of the trigger rib and the spring is not less than half of the length of the spring.
[0009] A first guide column for guiding the up and down movement of the key is provided in the accommodating cavity on the opposite side of the micro switch, and the first guide column is arranged closer to the side wall of the accommodating cavity than the center of the accommodating cavity.
[0010] A first guide column for guiding the up and down movement of the key is provided in the accommodating cavity on the opposite side of the micro switch, and a concave motor avoidance cavity is provided at the bottom of the accommodating cavity, and the first guide column is arranged radially outside the motor avoidance cavity.
[0011] A spring positioning column extending downward and a second guide column for guiding the up and down movement of the key are provided on the side of the key facing the accommodating cavity, a spring is sleeved on the spring positioning column, and the spring positioning column is arranged between the trigger rib and the second guide column.
[0012] The trigger rib, the spring positioning column and the second guide column are located on the same straight line.
[0013] The spring positioning column is provided with one and is located between the trigger rib and the second guide column; or, the spring positioning column is provided with multiple, and at least one of the spring positioning columns is provided close to the trigger rib, and at least one of the spring positioning columns is provided close to the second guide column; or, the spring positioning column is provided with one and is provided close to the trigger rib, a spring is provided on the second guide column, and the second guide column is reused as the spring positioning column.
[0014] A first guide column for guiding the up and down movement of the button is provided in the accommodating cavity. The first guide column penetrates axially, and the bottom of the first guide column is connected to the inner cavity of the shell. Part of the wiring harness connected to the motor extends from the bottom of the first guide column into the first guide column for accommodation.
[0015] A mounting groove for mounting the micro switch is provided in the accommodating cavity, and a stop plate is provided on the top of the mounting groove to limit the upward movement of the micro switch; alternatively, the housing further includes a shell body and a decorative piece covering the shell body, and the top of the decorative piece is opened to form the accommodating cavity.
[0016] The trigger rib comprises a first rib extending along the length direction of the trigger spring piece and a second rib cross-connected with the first rib, wherein two second ribs are provided and are respectively arranged at two ends of the first rib; or, the trigger rib is a protrusion.
[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0018] 1. In the food processor of the present invention, a spring sheet is arranged above the contact point, and the trigger rib presses down the spring sheet to contact the contact point, so that the trigger rib does not need to be arranged directly opposite the contact point but only needs to cover the contact point, and the installation accuracy requirement for the trigger rib is relatively reduced; on this basis, the use of a long strip of trigger rib can increase the contact area between the trigger rib and the spring sheet. Under the condition that the trigger rib covers the contact point, the user's requirement for the accuracy of the button pressing position can be reduced, and the user can trigger the micro switch at any position of the button pressed. Moreover, the large contact area between the trigger rib and the spring sheet can realize the stable pressing of the spring sheet by the trigger rib, and the feedback to the user is good. In addition, when the trigger rib and the spring sheet have a certain contact area and the trigger rib covers the contact point, it can be avoided that when the cantilever end of the spring sheet is pressed down, the spring sheet bulges upward, which is not conducive to contacting the contact point and causes trigger failure, thereby improving the success rate of effective triggering.
[0019] 2. As a preferred embodiment, the length of the overlapping plumb line projection of the trigger rib and the spring is not less than half the length of the spring. With such a trigger rib length, whether the trigger rib is located at the cantilever end close to the spring, the cantilever end far from the spring, or directly opposite the spring, the contact area between the trigger rib and the spring can be achieved to avoid the spring from being bulged due to local stress concentration when the spring is compressed, and ensure that the spring acts normally on the contact point; moreover, the longer the trigger rib is, the more conducive it is to the overall movement of the spring, which can reduce the risk of local deformation of the spring, and the larger the connection area between the trigger rib and the button, the more conducive it is to ensure that the trigger rib presses down the spring when the user presses the button at a position far from the trigger rib.
[0020] 3. As a preferred embodiment, a first guide post for guiding the up and down movement of the key is provided in the accommodating cavity on the opposite side of the micro switch, and the first guide post is arranged closer to the side wall of the accommodating cavity than the center of the accommodating cavity. The first guide post is arranged at a distance from the opposite side of the micro switch, and a fulcrum can be formed at the position of the first guide post when the user presses the key, forming a laborious lever with the first guide post as the fulcrum, which is conducive to increasing the triggering area, and can ensure effective triggering even when pressing the key at a position far away from the micro switch, that is, whether the user presses the key with the whole palm or presses the key with a single or several fingers at any position, the micro switch can be triggered, which improves the triggering success rate and reduces the operation requirements for the user. In particular, when there is only one key or two keys are symmetrically provided, the overall area of each key is relatively large, and there is randomness when the user presses the key position, which is not necessarily exactly above the trigger rib. However, since a laborious lever is formed between the first guide post and the micro switch in the present application, the triggering area of the key occupies most of the key, so that even when the user presses the key at the most unfavorable pressing position far away from the micro switch, a good triggering effect can be achieved.
[0021] 4. As a preferred embodiment, a first guide column for guiding the up and down movement of the button is provided on the opposite side of the micro switch in the accommodating cavity, and a concave motor avoidance cavity is provided at the bottom of the accommodating cavity, and the first guide column is arranged radially outside the motor avoidance cavity. By providing the first guide column, the button can be stably pressed down and reset, and the triggering stability is further improved. The first guide column is arranged radially outside the motor avoidance cavity. When the first guide column adopts a hollow structure and is connected to the inner cavity of the shell, a certain space can be provided below the first guide column, so that part of the wiring harness can be extended from the bottom of the first guide column into the first guide column for storage, so as to improve the arrangement of the wiring harness in the main machine; and if the first guide column is arranged above the motor avoidance cavity, the space between the button and the accommodating cavity will become higher, which will cause the height of the whole machine to become higher and the center of gravity to become higher, which is not conducive to the stable operation of the machine.
[0022] In addition, the first guide column is arranged on the radial outside of the motor avoidance cavity to increase the distance between the micro switch and the motor. When the user presses the button, a fulcrum can be formed at the position of the first guide column, forming a labor-intensive lever with the first guide column as the fulcrum, which is conducive to increasing the triggering area. Even if the button is pressed at a position far away from the micro switch, effective triggering can be guaranteed, thereby improving the triggering success rate and reducing the operation requirements for the user.
[0023] 5. As a preferred embodiment, a spring positioning column extending downward and a second guide column for guiding the up and down movement of the key are provided on the side of the key facing the accommodating cavity, a spring is sleeved on the spring positioning column, and the spring positioning column is arranged between the trigger rib and the second guide column. By making the force point of reset located between the trigger rib and the second guide column, it is convenient for the key to reset quickly.
[0024] 6. As a preferred embodiment, the spring positioning column is provided and is located between the trigger rib and the second guide column. This embodiment can simplify the structural configuration and installation while ensuring the key rebound effect.
[0025] In another embodiment, the spring positioning column is provided in plurality, and at least one of the spring positioning columns is provided close to the trigger rib, and at least one of the spring positioning columns is provided close to the second guide column. In the case where the trigger rib and the second guide column are far apart, by providing a plurality of spring positioning columns and providing spring positioning columns close to the trigger rib and the second guide column, it is possible to ensure that the key rebounds quickly and stably, and avoid the problem of key jamming due to insufficient rebound force.
[0026] In another embodiment, the spring positioning column is provided and is arranged close to the trigger rib, the second guide column is sleeved with a spring, and the second guide column is reused as a spring positioning column. Reusing the second guide column as a spring positioning column can reduce the number of special spring positioning columns, which is conducive to simplifying the key structure.
[0027] 7. As a preferred embodiment, a first guide column for guiding the up and down movement of the key is provided in the accommodating cavity, the first guide column is axially penetrated, the bottom of the first guide column is connected to the inner cavity of the shell, and part of the wire harness connected to the motor extends from the bottom of the first guide column into the first guide column for accommodation. In this embodiment, in addition to being used for key movement guidance, the first guide column is also used for storing part of the wire harness, which is a dual purpose, and a special wire harness storage structure can be omitted, which is conducive to simplifying the configuration of the host.
[0028] 8. As a preferred embodiment, a mounting groove for mounting the micro switch is provided in the accommodating cavity, and a stop plate is provided on the top of the mounting groove to limit the upward movement of the micro switch. By providing the stop plate, when the host is not installed on the cup body, it can prevent the user from accidentally operating the connecting rod below the micro switch and pushing the micro switch out of the mounting groove; when the host is installed in place, the stop plate and the connecting rod limit the upper and lower positions of the micro switch, which can ensure the stability of the position of the micro switch and ensure the reliability of the key triggering.
[0029] 9. As a preferred embodiment, the trigger rib includes a first rib extending along the length direction of the trigger spring and a second rib cross-connected with the first rib, and the second rib is provided with two and respectively arranged at both ends of the first rib. The use of a spliced rib-type trigger rib shape is conducive to saving materials and reducing costs while ensuring the trigger effect.
[0030] Alternatively, the trigger rib is a convex block. Arranging the trigger rib as a convex block is convenient for processing and has low processing difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figures 1 to 7As shown, the present application provides a food processor, including a main unit 10, which includes a shell 11 and a button 13 from bottom to top, the shell 11 including a shell body and a decorative piece 12 covering the shell body, the top of the decorative piece is opened to form the accommodating cavity, a motor 111 is arranged in the shell 11, the decorative piece 12 covers the top of the shell body, the decorative piece 12 is provided with an accommodating cavity 121 with a top opening, the button 13 covers the top opening of the accommodating cavity 121, a micro switch 14 is arranged in the accommodating cavity 121, a contact 141 is arranged on the top of the micro switch 14, a sheet-shaped spring 142 is arranged obliquely above the contact 141, and a trigger rib 15 is arranged above the corresponding spring rib 142 on the button 13, the trigger rib 15 extends into a long strip along the length direction of the spring rib 142, and the plumb projection of the trigger rib 15 covers the contact 141.
[0047] In the food processor of the present application, the spring piece 142 is arranged above the contact 141, and the trigger rib 15 presses down the spring piece 142 to contact the contact 141, so that the trigger rib 15 does not need to be arranged directly opposite the contact 141 but only needs to cover the contact 141, and the installation accuracy requirement for the trigger rib 15 is relatively reduced; on this basis, the use of the long strip-shaped trigger rib 15 can increase the contact area between the trigger rib 15 and the spring piece 142, and under the condition that the trigger rib 15 covers the contact 141, the user's requirement for the accuracy of the pressing position of the button 13 can be reduced. The user can trigger the micro switch 14 by pressing any position of the button 13, and the large contact area between the trigger rib 15 and the spring 142 can enable the trigger rib 15 to stably press down the spring 142, giving the user a good hand feeling. In addition, when the trigger rib 15 and the spring 142 have a certain contact area and the trigger rib 15 covers the contact 141, it can be avoided that when the cantilever end of the spring 142 is pressed down, the spring 142 bulges upward, which is not conducive to contacting the contact 141 and causing trigger failure, thereby improving the success rate of effective triggering.
[0048] like Figures 1 to 3 As shown, the button 13 adopts an integrated cover-shaped structure. Based on the structure in which the trigger rib 15 and the spring 142 are arranged correspondingly, the user is not restricted in the pressing position when pressing the button 13, which reduces the operation requirements for the user. The user can press with the whole palm or use fingers to press partially to ensure the smooth triggering of the micro switch 14. Figure 5 As shown, the contact 141 is arranged away from the cantilever end of the spring sheet 142. Since the plumb projection of the trigger rib 15 covers the contact 141, it can be avoided that the trigger rib 15 only presses down the cantilever end of the spring sheet 142, causing the spring sheet 142 above the contact 141 to easily bulge and affect the triggering of the micro switch 14, thereby ensuring the effective triggering of the micro switch 14. Of course, it can be understood that the position of the contact 141 is not limited to Figure 5 Regardless of the position of the contact 141, the plumb projection of the trigger rib 15 covers the contact 141, thereby improving the trigger success rate.
[0049] It is understandable that in some other embodiments of the present application, the housing 11 may not include the decorative element 12, that is, the housing body alone constitutes the housing 11. The accommodating cavity is directly formed on the top of the housing 11.
[0050] like Figure 3 and Figure 4 As shown, the button 13 is provided with a plurality of buckles 131 which are circumferentially spaced and extend downward, and the decorative member 12 is provided with slots 123 which correspond one to one with the plurality of buckles 131. The button 13 is fixed to the decorative member 12 by the cooperation of the buckles 131 and the slots 123 and can have a small axial movement relative to the decorative member 12 to realize the pressing down and resetting of the button 13.
[0051] As a preferred embodiment, the length of the overlapping plumb line projection of the trigger rib 15 and the spring 142 is not less than half the length of the spring 142. Under such a length of the trigger rib 15, whether the trigger rib 15 is arranged at the cantilever end close to the spring 142, the cantilever end far away from the spring 142, or directly opposite to the spring 142, the contact area between the trigger rib 15 and the spring 142 can achieve the purpose of avoiding the spring 142 from being locally stressed and bulging when the spring 142 is compressed, and can ensure that the spring 142 acts normally on the contact point 141; moreover, the longer the length of the trigger rib 15 is, the more conducive it is to the overall movement of the spring 142, and the risk of local deformation of the spring 142 can be reduced, and the connection area between the trigger rib 15 and the button 13 becomes larger, which is conducive to ensuring that the trigger rib 15 presses down the spring 142 when the user presses the button 13 at a position far away from the trigger rib 15.
[0052] Specifically, in one embodiment, the length of the trigger rib 15 is equal to the length of the spring 142, and the centers of the two are arranged opposite each other. In another embodiment, the length of the trigger rib 15 is greater than the length of the spring 142, and the trigger rib 15 covers the entire spring 142. In yet another embodiment, the length of the trigger rib 15 is equal to the length of the spring 142, and the centers of the two are arranged in a staggered manner. The above examples are all conducive to processing the trigger rib 15 according to the length and position of the spring 142 and arranging the position of the trigger rib 15, which can reduce the precision requirements for processing and simplify the structure of the key 13.
[0053] In the prior art, when a user presses a button on the top of the host, the pressing is random, that is, the user's pressing position is not necessarily located just above the trigger rib. When the user's pressing position is far away from the trigger rib, the button is tilted. Even when the button is pressed to the lowest point, the side that tilts upward is just above the micro switch, that is, the trigger rib and the micro switch are far apart in the vertical direction, and the micro switch cannot be triggered normally. The user can only trigger the micro switch when it is just above or close to the trigger rib, which limits the user's convenience.
[0054] To this end, the present application provides a preferred implementation scheme, which aims to solve the problem that even when the user's pressing position is at the most unfavorable pressing position radially away from the micro switch, a good triggering effect can be achieved. Specifically, a first guide post 16 for guiding the up and down movement of the button 13 is provided on the opposite side of the micro switch 14 in the accommodating cavity 121, and the first guide post 16 is arranged closer to the side wall of the accommodating cavity 121 than the center of the accommodating cavity 121.
[0055] like Figure 2 As shown, a first guide column 16 is arranged farther away from the opposite side of the micro switch 14. When the user presses the button 13, a fulcrum can be formed at the position of the first guide column 16, forming a laborious lever with the first guide column 16 as the fulcrum, which is conducive to increasing the triggering area. Even if the button 13 is pressed at a position far away from the micro switch 14, effective triggering can be guaranteed. That is, no matter the user presses the button 13 with the entire palm or presses any position of the button 13 with a single finger or several fingers, the micro switch 14 can be triggered, thereby improving the triggering success rate and reducing the operation requirements for the user.
[0056] In particular, when there is only one key or two keys are symmetrically provided, the overall area of each key is relatively large, and the user's key pressing position is random, and it is not necessarily located exactly above the trigger rib. However, since a laborious lever is formed between the first guide column 16 and the micro switch 14 in the present application, the triggering area of the key 13 occupies most of the key 13, so that even when the user presses at the most unfavorable pressing position far away from the micro switch, a good triggering effect can be achieved.
[0057] by Figure 6 As explained in the simplified schematic diagram, it is assumed that after the user presses the button 13, there is an X displacement, and a Y displacement is formed at the position of the trigger rib 15. Through the cooperation of the first guide column 16 and the second guide column 17 on the button 13, a laborious lever with the first guide column 16 as the fulcrum is formed. In this way, X≤Y, the trigger area can be increased, such as Figure 7 The shaded area is the theoretical trigger area.
[0058] It is understandable that when the accommodating cavity is formed by a decorative element, it can also be expressed as that the first guide column 16 is arranged closer to the side wall of the decorative element 12 than to the center of the decorative element 12 .
[0059] like Figure 2 and Figure 4As shown, the micro switch 14 and the first guide column 16 are respectively arranged close to the side wall of the accommodating cavity 121 on their respective sides, so as to form the above-mentioned laborious lever, and when the user habitually presses the position between the micro switch 14 and the first guide column 16, it can ensure that the micro switch 14 is smoothly triggered, and the user operation requirements are low. In one embodiment, the first guide column 16 is connected to the side wall of the accommodating cavity 121. For example, the first guide column 16 adopts a semicircular structure and is enclosed with the side wall of the accommodating cavity 121 to form a circumferentially closed hollow guide column. On the one hand, the distance between the micro switch 14 and the first guide column 16 can be further increased, and on the other hand, the structural strength of the first guide column 16 can be improved to reduce the risk of deformation and cracking thereof and extend its service life.
[0060] As a preferred embodiment, a first guide column 16 for guiding the up and down movement of the button 13 is provided on the opposite side of the micro switch 14 in the accommodating cavity 121, and a concave motor avoidance cavity 122 is provided at the bottom of the accommodating cavity 121, and the first guide column 16 is arranged on the radial outside of the motor avoidance cavity 122.
[0061] like Figure 2 and Figure 4 As shown, by setting the first guide column 16, it can be ensured that the button 13 is stably pressed down and reset, and the triggering stability is further improved. The first guide column 16 is arranged on the radial outside of the motor avoidance cavity 122. When the first guide column 16 adopts a hollow structure and is connected to the inner cavity of the shell 11, a certain space can be provided below the first guide column 16, so that part of the wiring harness can extend from the bottom of the first guide column 16 into the first guide column 16 for storage, thereby improving the arrangement of the wiring harness in the host 10; and if the first guide column 16 is arranged above the motor avoidance cavity 122, the space between the button 13 and the decorative component 12 will become higher, which will cause the height of the whole machine to become higher and the center of gravity to become higher, which is not conducive to the stable operation of the machine.
[0062] In addition, the first guide column 16 is arranged on the radial outside of the motor avoidance cavity 122 to increase the distance between the micro switch 14 and the user can form a fulcrum at the position of the first guide column 16 when pressing the button 13, forming a labor-intensive lever with the first guide column 16 as the fulcrum, which is conducive to increasing the triggering area. Even if the button 13 is pressed at a position far away from the micro switch 14, effective triggering can be guaranteed, thereby improving the triggering success rate and reducing the operation requirements for the user.
[0063] Preferably, the micro switch 14 is arranged radially outside the motor avoidance cavity 122 so that the connecting rod 24 below the micro switch 14 avoids the motor 111, thereby achieving a reasonable layout between the structures.
[0064] As a preferred embodiment, a spring positioning column 18 extending downward and a second guide column 17 for guiding the up and down movement of the button 13 are provided on the side of the button 13 facing the accommodating cavity 121. A spring 19 is sleeved on the spring positioning column 18, and the spring positioning column 18 is arranged between the trigger rib 15 and the second guide column 17. By making the force point of reset be located between the trigger rib 15 and the second guide column 17, it is beneficial for the button 13 to be reset quickly.
[0065] In one embodiment, the trigger rib 15 , the spring positioning column 18 and the second guide column 17 are located on the same straight line. This embodiment is conducive to further improving the reset rate of the button 13 .
[0066] like Figure 3 As shown, it is an example with two spring positioning columns 18. The trigger rib 15, the two spring positioning columns 18 and the second guide column 17 are located on the same straight line. The four are located on a straight line where a diameter of the button 13 is located, which can reasonably utilize the space and ensure that the button 13 can be quickly reset.
[0067] In another embodiment, the number and position of the spring positioning column 18 can be flexibly set to achieve the effect of quickly resetting the button 13. In this embodiment, it is not required whether the trigger rib 15, the spring positioning column 18 and the second guide column 17 are located on the same straight line.
[0068] Specifically, in the first example, one spring positioning column 18 is provided and is located between the trigger rib 15 and the second guide column 17. This embodiment can simplify the structural configuration and installation under the premise of ensuring the rebound effect of the key 13. In this embodiment, the outer diameter of the spring 19 provided on the spring positioning column 18 is not less than 1 / 3 of the diameter of the key 13, so as to ensure that the key 13 can rebound quickly when one spring 19 is used.
[0069] In the second example, multiple spring positioning columns 18 are provided, and at least one spring positioning column 18 is provided near the trigger rib 15, and at least one spring positioning column 18 is provided near the second guide column 17. In the case where the trigger rib 15 and the second guide column 17 are far apart, by providing multiple spring positioning columns 18 and providing spring positioning columns 18 near the trigger rib 15 and the second guide column 17, it is possible to ensure that the button 13 rebounds quickly and stably, and avoid the problem of the button 13 being stuck due to insufficient rebound force. Figure 2 As described above, there are two spring positioning columns 18, which are respectively arranged close to the trigger rib 15 and the second guide column 17, so that the button 13 can rebound smoothly as a whole and avoid the phenomenon of inconsistent local rebound rate.
[0070] In the third example, a spring positioning column 18 is provided and is arranged near the trigger rib 15, a spring 19 is sleeved on the second guide column 17, and the second guide column 17 is reused as the spring positioning column 18. Reusing the second guide column 17 as the spring positioning column 18 can reduce the provision of a special spring positioning column 18, which is conducive to the simplification of the structure of the button 13. In this example, the first guide column 16 in the accommodating cavity 121 is hollow, and the second guide column 17 can be inserted into the first guide column 16 and slide, so that the use of the spring 19 is not affected when the spring 19 is sleeved on the upper end of the second guide column 17.
[0071] Based on the above embodiments and examples, the cooperation between the first guide post 16 in the accommodating cavity 121 and the second guide post 17 on the button 13 is described. Figure 2 As shown, the first guide post 16 is hollow, and the second guide post 17 can be inserted into and slide in the first guide post 16. In another embodiment, the second guide post 17 is hollow, and the first guide post 16 can be inserted into and slide in the second guide post 17.
[0072] Furthermore, a third guide post 20 is provided in the accommodating cavity 121 for use in conjunction with the spring positioning post 18. Figure 2 and Figure 4 As shown, the third guide column 20 is hollow so that the lower end of the spring positioning column 18 can extend into the third guide column 20 and slide when the key 13 moves downward.
[0073] As a preferred embodiment, a first guide column 16 for guiding the up and down movement of the button 13 is provided in the accommodating cavity 121. The first guide column 16 is axially penetrated, and the bottom of the first guide column 16 is communicated with the inner cavity of the housing 11. Part of the wire harness connected to the motor 111 extends from the bottom of the first guide column 16 into the first guide column 16 for accommodation. In this embodiment, in addition to being used for guiding the movement of the button 13, the first guide column 16 is also used for storing part of the wire harness. It is a dual-purpose piece, and a special wire harness storage structure can be omitted, which is conducive to simplifying the configuration of the host 10.
[0074] In one embodiment, the live wire from the power cord connected to the host 10 is connected to the micro switch 14, the micro switch 14 is connected to the motor 111, and the neutral wire of the motor 111 is connected to the neutral wire from the power cord and can be inserted into the first guide column 16 for storage, which can prevent the wiring harness connection from being exposed in the inner cavity of the housing 11, which is easy to shake and disconnect, and cause safety problems when water enters the host 10. By storing the wiring harness connection, it is equivalent to providing a limit and shielding, which can ensure the reliability of the connection and waterproof. Preferably, a wiring cap 25 is provided on the outer side of the wiring harness connection, and the wiring cap 25 is inserted into the first guide column 16 for easy operation.
[0075] In another embodiment, Figure 2 As shown, part of the wiring harness 112 on the motor 111 is bundled and then extended into the first guide column 16 for storage. Preferably, a wiring cap 25 is provided on the outer side of the wiring harness 112, and the wiring harness 112 is extended into the first guide column 16 through the wiring cap 25, which is easy to operate. By storing the wiring harness, it is possible to avoid these wiring harnesses being scattered in the inner cavity of the housing 11, which may cause safety problems.
[0076] As a preferred embodiment, a mounting groove 21 for mounting the micro switch 14 is provided in the accommodating cavity 121 , and a stop plate 22 is provided on the top of the mounting groove 21 to limit the upward movement of the micro switch 14 .
[0077] like Figure 4 As shown, by setting the stop plate 22, when the host 10 is not installed on the cup body, it can prevent the user from accidentally operating the connecting rod 24 under the micro switch 14 and pushing the micro switch 14 out of the installation groove 21; when the host 10 is installed in place, the stop plate 22 and the connecting rod 24 limit the upper and lower positions of the micro switch 14, which can ensure the stability of the position of the micro switch 14 and ensure the reliability of the triggering of the button 13.
[0078] As a preferred embodiment, the trigger rib 15 includes a first rib 151 extending along the length direction of the trigger spring 142 and a second rib 152 cross-connected with the first rib 151. Two second ribs 152 are provided and are respectively arranged at both ends of the first rib 151. Figure 3 As shown, the use of the trigger rib 15 in the form of spliced ribs is beneficial to saving materials and reducing costs while ensuring the triggering effect. Figure 3 The middle trigger rib 15 forms two connected cross-shaped ribs.
[0079] In another embodiment, the trigger rib 15 is a bump. The trigger rib 15 is set as a bump, which is easy to process and has low processing difficulty.
[0080] It is understandable that in other embodiments, the trigger ribs 15 may also adopt other shapes, such as non-straight ribs, such as ribs extending in a wave shape.
[0081] Based on the structure of the main unit 10, the food processor of the present application further includes a cup body assembly 23, such as Figure 1 and Figure 2 As shown, the host 10 is arranged above the cup body assembly 23. The specific structure of the cup body assembly 23, the installation and use of the host 10 can be understood by referring to the solutions of the prior art, and will not be repeated here.
[0082] like Figure 2As shown, a connecting rod 24 is provided below the micro switch 14. When the main unit 10 is not installed on the cup body assembly 23, the lower end of the connecting rod 24 can extend out of the bottom of the main unit 10 to prevent the micro switch 14 from being triggered accidentally. When the main unit 10 is installed in the cup body assembly 23, the connecting rod 24 is pushed by the cup cover to make the micro switch 14 reach a suitable position, thereby ensuring the normal triggering and use of the micro switch 14 and improving the safety of use.
