Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and in particular relates to a food processing machine which can prevent accidental touch. Background Art

[0002] Existing food processors usually include a main unit with a built-in motor, a cup body detachably arranged on the main unit, and a cup cover screwed on the cup body and enclosing the cup body to form a grinding chamber. When a user uses the food processor to process food, the user places the food in the grinding chamber and then closes the cup cover on the cup body, and then turns on the main unit. The grinding device in the cup body rotates at a high speed driven by the motor to process the food. However, when the user is in use, the main unit may be opened without the cup lid being installed in place. At this time, the cup lid and the cup body are not tightly connected, which may cause the food to splash out of the crushing chamber or even the cup lid to separate from the cup body. In order to solve the above technical problems, Chinese utility model patent CN202222270651.5 discloses a safe food processor, in which a trigger structure is provided on the cup lid, and a follower cooperating with the trigger structure is provided in the cup body, and a micro switch cooperating with the motor is provided in the main unit. When the cover body is screwed into place and the trigger part of the trigger structure abuts against the follower, the follower is squeezed downward by the trigger part, so that the follower moves downward as a whole to trigger the micro switch, that is, the motor can only start working when the cover body is screwed into place, which avoids the situation where the cover body is not tightened and the motor starts working, causing the cover body and the cup body to separate and cause food to overflow. However, in this solution, the follower is partially located inside the handle and partially protrudes from the handle. During use, especially when holding the handle, the user's fingers may accidentally touch the top of the follower, causing the follower to move downward and drive the microswitch to trigger the motor, resulting in the situation where food can be processed without the cup lid being screwed into place, seriously affecting the consumer's experience. Utility Model Content

[0003] The utility model provides a food processing machine with an anti-mis-touch function, which is used to solve the problem that a follower for triggering a micro switch in the food processing machine is exposed outside a handle, so that a user may accidentally touch the follower and cause mis-triggering of a motor.

[0004] The technical solution adopted by the utility model is:

[0005] A food processing machine that prevents accidental touch, comprises a main unit with a built-in motor and a detachable cup body arranged above the main unit and having a grinding chamber, the cup body comprising a grinding cup with a grinding device arranged therein and a cup cover covering the grinding cup, a micro switch for controlling the on and off of the motor is arranged in the main unit, the cup cover is provided with a trigger part, the cup body is provided with a switch connecting rod that can move with the trigger part, the grinding cup is also provided with a handle, the handle and the outer side wall of the grinding cup are surrounded to form a cavity, the switch connecting rod comprises a connecting rod body located in the cavity and a driven part whose top end can extend into the interior of the cup body and cooperates with the trigger part, a shielding member is provided inside the cup body to shield between the driven part and the grinding chamber, and the shielding member is provided with an escape opening for the trigger part to pass through.

[0006] This solution expands the functionality of the food processor and improves the user experience by detachably installing the cup body on the main machine. Users can choose different types of cup bodies to install on the main machine and select the cup body type according to their needs. At the same time, the detachable installation of the cup body can be used to clean the cup body separately after disassembly, which is conducive to more thorough cleaning of the cup body and avoids the residual dirt in the cup body causing the cup body to produce odor.

[0007] At the same time, by setting a trigger part on the cup cover and setting a switch connecting rod on the cup body, the trigger part cooperates with the switch connecting rod, and the trigger part drives the driven part to drive the micro switch to operate, that is, the trigger part and the switch connecting rod are coordinated by assembling the cup cover and the cup body to achieve the cooperation of the trigger part and the switch connecting rod, so as to realize the micro switch operation. And because the switch connecting rod includes a connecting rod body located in the cavity and a driven part that can be inserted into the cup body, the driven part is reasonably modified according to the original structure of the food processor to achieve protection of the driven part, and the driven part is inserted into the cup body, and the user cannot directly touch the driven part, which effectively avoids the situation where the driven part is exposed to the outside world, resulting in the cup cover not being screwed in place, and the user accidentally touching the driven part, causing the micro switch to trigger the motor, ensuring that the micro switch can trigger the motor only when the cup cover is screwed in place, thereby improving the stability of the whole machine.

[0008] In addition, a shielding member is provided inside the cup body to achieve a shielding and protective effect on the driven part extending into the cup body, to prevent the material in the cup body from splashing onto the driven part and causing adhesion, which is beneficial to keeping the driven part clean and avoiding residual dirt or bacteria on the driven part, thereby ensuring the linkage stability of the driven part. A avoidance port is provided on the shielding member to ensure that when the cup cover is closed, the trigger part can penetrate into the shielding member through the avoidance port and link with the driven part located inside to open the micro switch, while effectively protecting the driven part and realizing the operation of the micro switch, and at the same time, shielding and protecting the contact part between the trigger part and the driven part, further ensuring the linkage stability of the trigger part and the driven part. At the same time, the shielding member protects the driven part and the trigger part, preventing the material splashing during the processing process from causing the linkage disconnection between the trigger part and the driven part, and further ensuring the reliability of the use of the micro switch. At the same time, the shielding member and the avoidance port located on the shielding member facilitate the determination of the closing direction of the cup cover according to the position of the trigger part and the driven part, which is beneficial to quickly and accurately realize the accurate alignment of the cup cover, realize the opening of the micro switch, and enhance the user experience.

[0009] In a preferred implementation of an anti-accidental-touch food processor, an isolation structure is further provided between the avoidance opening and the trigger portion, so that after the cup cover and the grinding cup are screwed into place, the driven portion is isolated from the grinding chamber.

[0010] By setting up an isolation structure, the driven part can be further protected when the motor is working. Due to the existence of the avoidance port, the shielding member is connected to the outside. In order to allow the trigger part to smoothly pass through the avoidance port, and due to high frequency use, there is easily a gap between the trigger part and the avoidance port. During the operation of the food processor, especially when the motor is running at a high speed, it is easy to cause materials to splash to the avoidance port, causing a cleaning burden, and even causing pollution to the trigger part and the driven part located inside the shielding member. The isolation structure isolates the driven part from the grinding chamber after the cup cover and the grinding cup are screwed into place, preventing the material from entering the avoidance port from the gap and causing pollution to the driven part, thereby further ensuring the linkage stability of the driven part and the trigger part.

[0011] In a preferred implementation of an anti-accidental-touch food processor, the isolation structure includes a sealing member disposed between the trigger portion and the avoidance opening.

[0012] The sealing effect at the avoidance port is achieved by setting a seal when the trigger part and the driven part are linked. The seal is set between the trigger part and the avoidance port, and its specific structural position can be set at the bottom of the trigger part or the top of the avoidance port according to the matching structure of the cup body and the cup cover. When the trigger part penetrates the avoidance port, the sealing effect at the avoidance port is achieved to prevent the material from entering the avoidance port from the gap and contaminating the driven part, reduce the cleaning burden, and improve the linkage stability of the trigger part and the driven part. In addition, the setting form of the seal is simple, the processing difficulty is low, the cost is low, and it is easy to achieve a good assembly sealing effect.

[0013] In a preferred implementation of an anti-accidental-touch food processor, the trigger portion is a turn buckle arranged on the side of the cup cover, and the sealing member is sleeved on the outside of the turn buckle.

[0014] The trigger part is in the form of a screw button. As the cup cover is screwed in, the trigger part penetrates into the avoidance opening in the direction of rotation to trigger the driven part. On the one hand, the contact between the trigger part and the driven part is simple in this form. On the other hand, as the trigger part penetrates, the cup cover is reminded to be in place when it is screwed in, which is conducive to the rapid and accurate positioning of the cup cover. The trigger part is arranged on the side of the cup cover to avoid occupying the crushing chamber space after the cup cover is in place. The sealing part is sleeved on the outside of the screw button. As the trigger part penetrates, the sealing part achieves a sealing effect at the avoidance opening. Since the cup cover can be removed separately, it is convenient to clean the sealing part sleeved on the outside of the screw button, so that it is kept clean every time it is used, achieving a good sealing effect.

[0015] In a preferred implementation of an anti-accidental-touch food processor, the cup cover is screwed together with the grinding cup and the shielding member is a cover-like structure with an escape opening only along the screw-in direction of the cup cover, so that after the cup cover is screwed into place, the trigger portion closes the escape opening.

[0016] The shielding member is set as a cover-shaped structure with a avoidance opening only along the direction in which the cup cover is screwed in. When the cup cover is screwed in, the trigger part directly penetrates the avoidance opening during the screwing process, and the trigger part and the driven part are quickly docked. The cover-shaped structure forms circumferential protection for the driven part and at least part of the trigger part inside the shielding member. The avoidance opening is closed by the cooperation between the trigger part and the shielding member, effectively ensuring the cleanliness of the driven part and preventing material splashing. It is also convenient for users to realize the linkage between the trigger part and the driven part with less effort when screwing the cup cover, which improves the user experience.

[0017] In a preferred implementation of an anti-accidental-touch food processor, the grinding cup is provided with a step portion with the step surface facing upward, the step surface is provided with a through hole for the driven portion to pass through, and the shielding member is formed above the step surface.

[0018] The shielding member and other components in the pulverizing cup are partitioned by providing a step portion, and since the shielding member is formed above the step surface of the step portion, the step portion can shield the material splashing in the pulverizing chamber, further reducing the pulverized material splashing to the shielding member, which is beneficial to ensuring the cleanliness of the shielding member, further avoiding the adhesion of materials at the avoidance port, and avoiding the material from entering the avoidance port and contaminating the driven part; at the same time, the step portion is provided with a through hole for the driven part to pass through, on the one hand, the driven part can be extended into the shielding member through the through hole, and on the other hand, the step portion realizes circumferential limiting and supporting effects on the driven part passing through the through hole, which is beneficial to ensuring the stability of the switch connecting rod, thereby ensuring the linkage effect between the trigger part and the driven part, and ensuring the stable opening of the micro switch and the stable operation of the motor.

[0019] In a preferred implementation of an anti-accidental-touch food processor, the cup cover is screwed and installed with the grinding cup, the driven part is provided with a guide bevel, and the guide bevel faces the screw-in direction of the trigger part.

[0020] The screwing installation of the cup cover and the crushing cup facilitates the alignment contact between the trigger part and the driven part. During the screwing process, the trigger part directly contacts the driven part, and the screwing prompt of the cup cover is obvious, which provides a better user experience. A guide slope facing the trigger part is set on the driven part. When the trigger part is screwed in, the guide slope guides the linkage between the trigger part and the driven part, so that the trigger part continues to be screwed in along the direction of the guide slope to achieve linkage with the driven part, thereby improving the coordination efficiency between the trigger part and the driven part and improving the user experience.

[0021] In a preferred implementation of an anti-accidental-touch food processor, one of the driven part and the trigger part is provided with a rotation-stopping protrusion, and the other of the two is provided with a rotation-stopping groove cooperating with the rotation-stopping protrusion.

[0022] By setting a stop protrusion and a stop groove that cooperates with it, the limit is realized after the driven part and the trigger part are linked, so as to prevent the driven part and the trigger part from being separated. When the motor is running at a high speed, the cup body will inevitably shake, and the shielding member inside the cup body and the shielding member will shake with the cup body. The stop protrusion and the stop groove prevent the trigger part and the driven part from loosening, and also prevent the cup cover and the cup body from slipping, so as to further ensure the accurate covering position of the cup cover and the cup body, and the cooperation of the stop protrusion and the stop groove makes the cup cover and the cup body have a stronger feel of being in place, effectively ensuring the triggering effect of the micro switch.

[0023] In a preferred implementation of an anti-accidental-touch food processor, a first downward limiting surface is provided on the outer side wall of the grinding cup, and the connecting rod body and the driven part are bent to form a second upward limiting surface, and the first limiting surface and the second limiting surface are axially limited.

[0024] The connecting rod body is located in the cavity, and the limiting of the connecting rod body is achieved through the cooperation between the first limiting surface and the second limiting surface, which is beneficial to ensuring the stable position of the connecting rod body, so that the driven part connected to it can accurately extend into the cup body and link with the trigger part, thereby further improving the working stability of the micro switch; and the second limiting surface is formed between the connecting rod body and the driven part, and cooperates with the first limiting surface to strengthen the supporting effect on the driven part, which is beneficial to ensuring the connection stability between the driven part and the trigger part.

[0025] In a preferred implementation of an anti-accidental-touch food processor, the connecting rod body extends vertically in the cavity and the driven part extends laterally into the grinding cavity, the side wall of the grinding cup is provided with a reciprocating hole for the driven part to pass through and reciprocate vertically, and the shielding member is formed on the outside of the reciprocating hole.

[0026] By setting the driven part to extend laterally into the crushing chamber, a bending part is formed with the vertical connecting rod body during the laterally extending process of the driven part, which is beneficial to enhancing the overall stability of the switch connecting rod. The reciprocating hole usually limits the driven part to avoid the vertical deviation of the driven part, which causes the laterally extended part to be insufficient for linkage with the trigger part, thereby further ensuring the activation stability of the micro switch. At the same time, by setting the driven part to move vertically along the reciprocating hole, the trigger part and the driven part can realize linkage and disengagement. The shielding member is formed on the outside of the reciprocating hole to shield and protect the driven part that extends laterally into the crushing chamber, thereby avoiding material splashing to the driven part to cause pollution, thereby further ensuring the action stability of the driven part and ensuring the smooth activation of the micro switch.

DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present invention and the features in each embodiment may be combined with each other without conflict.

[0044] like Figures 1 to 12 As shown, the utility model provides a food processing machine that prevents accidental touch, including a main unit 10 with a built-in motor 20 and a detachable cup body 30 provided on the main unit 10 and having a grinding chamber, the cup body 30 including a grinding cup provided with a grinding device and a cup cover 40 covering the grinding cup, a micro switch 90 for controlling the on and off of the motor 20 is provided in the main unit 10, the cup cover 40 is provided with a trigger part 401, the cup body 30 is provided with a switch connecting rod 50 that can move with the trigger part 401, the grinding cup is also provided with a handle 80, the handle 80 and the outer side wall of the grinding cup are surrounded to form a cavity 304, the switch connecting rod 50 includes a connecting rod body 501 located in the cavity 304 and a driven part 502 whose top end can extend into the interior of the cup body 30 and cooperate with the trigger part 401, a shielding member 60 is provided on the inner side of the cup body 30 to block between the driven part 502 and the grinding chamber, and the shielding member 60 is provided with an avoidance opening 601 for the trigger part 401 to pass through.

[0045] The present invention provides a solution in which the cup body 30 is detachably mounted on the main unit 10, and the user can select different types of cup bodies 30 to be installed on the main unit 10, and select the type of cup body 30 according to the needs, thereby expanding the functionality of the food processor and improving the user experience. At the same time, the detachable installation of the cup body 30 enables the cup body 30 to be cleaned separately after being disassembled, which is conducive to a more thorough cleaning of the cup body 30 and avoids the residual dirt in the cup body 30 causing the cup body 30 to produce odor.

[0046] At the same time, a trigger part 401 is provided on the cup cover 40, and a switch connecting rod 50 is provided on the cup body 30. The trigger part 401 cooperates with the switch connecting rod 50, and the trigger part 401 drives the driven part 502 to drive the micro switch 90 to operate. That is, the trigger part 401 cooperates with the switch connecting rod 50 through the assembly and cooperation of the cup cover 40 and the cup body 30, thereby realizing the operation of the micro switch 90. And because the switch connecting rod 50 includes a connecting rod body 501 located in the cavity 304 and a driven part 502 that can be extended into the cup body 30, the protection of the driven part 502 is achieved by reasonable modification according to the original structure of the food processor. The driven part 502 extends into the interior of the cup body 30, and the user cannot directly touch the driven part 502, which effectively avoids the situation where the driven part 502 is exposed to the outside and the cup cover 40 is not screwed into place, and the user accidentally touches the driven part 502, causing the micro switch 90 to trigger the motor 20. It is ensured that the micro switch 90 can trigger the motor 20 only when the cup cover 40 is screwed into place, thereby improving the working stability of the whole machine.

[0047] In addition, if Figure 3 , Figure 4As shown, a shielding member 60 is provided inside the cup body 30 to achieve a shielding and protective effect on the driven part 502 extending into the cup body 30, to prevent the material in the cup body 30 from splashing onto the driven part 502 and causing adhesion, which is beneficial to keeping the driven part 502 clean, and to prevent the existence of residual dirt or bacteria on the driven part 502, thereby ensuring the linkage stability of the driven part 502. A avoidance opening 601 is provided on the shielding member 60 to ensure that when the cup cover 40 is closed, the trigger part 401 can penetrate into the shielding member 60 through the avoidance opening 601 and link with the driven part 502 located inside to turn on the micro switch 90, effectively protecting the driven part 502 while realizing the operation of the micro switch 90, and at the same time, shielding and protecting the contact part between the trigger part 401 and the driven part 502, further ensuring the linkage stability between the trigger part 401 and the driven part 502. At the same time, the shielding member 60 protects the driven part 502 and the trigger part 401, preventing the material from splashing during processing and causing the trigger part 401 to disconnect from the driven part 502, further ensuring the reliability of the micro switch 90. At the same time, the shielding member 60 and the avoidance opening 601 located on the shielding member 60 facilitate the determination of the closing direction of the cup cover 40 according to the position of the trigger part 401 and the driven part 502, which is conducive to quickly and accurately realizing the accurate alignment of the cup cover 40, realizing the opening of the micro switch 90, and improving the user experience.

[0048] Preferably, the height and width of the shielding member 60 are greater than the width and height of the portion of the driven part 502 extending into the cup body 30, so as to achieve a better shielding and protecting effect on the driven part 502 and prevent the material from entering the avoidance port 601 from the gap and contaminating the driven part 502.

[0049] like Figure 2 As shown, preferably, an elastic reset member connected to the switch link 50 is provided in the cavity 304, such as a spring 5023 connected to the driven part 502, and the spring 5023 is expanded and contracted in the vertical direction, so that after the driven part 502 is separated from the trigger part 401, the driven part 502 is reset under the action of the spring 5023, so as to realize the next linkage with the trigger part 401.

[0050] As a preferred embodiment of the present application, an isolation structure is further provided between the avoidance opening 601 and the triggering portion 401 so that after the cup cover 40 and the grinding cup are screwed into place, the driven portion 502 is isolated from the grinding chamber.

[0051] By setting up an isolation structure, the driven part 502 can be further protected when the motor 20 is working. Due to the existence of the avoidance port 601, the shielding member 60 is connected to the outside. In order to allow the trigger part 401 to smoothly pass through the avoidance port 601, and due to high frequency use, there is a gap between the trigger part 401 and the avoidance port 601. During the operation of the food processor, especially when the motor 20 is running at a high speed, it is easy to cause materials to splash to the avoidance port 601, causing a cleaning burden, and even causing pollution to the trigger part 401 and the driven part 502 located inside the shielding member 60. The isolation structure isolates the driven part 502 from the grinding chamber after the cup cover 40 and the grinding cup are screwed into place, so as to prevent the material from entering the avoidance port 601 from the gap and causing pollution to the driven part 502, thereby further ensuring the linkage stability between the driven part 502 and the trigger part 401.

[0052] like Figure 5 As shown, as an example of this embodiment: the isolation structure includes a sealing member 70 disposed between the trigger portion 401 and the avoidance opening 601 .

[0053] The sealing effect at the avoidance opening 601 is achieved by setting the sealing member 70 when the trigger part 401 and the driven part 502 are linked. The sealing member 70 is set between the trigger part 401 and the avoidance opening 601. Its specific structural position can be set at the bottom of the trigger part 401 or the top of the avoidance opening 601 according to the matching structure of the cup body 30 and the cup cover 40. When the trigger part 401 penetrates the avoidance opening 601, the sealing effect at the avoidance opening 601 is achieved. The sealing member 70 realizes the interference fit between the trigger part 401 and the avoidance opening 601, and the splashing material is isolated at the avoidance opening 601, thereby preventing the material from entering the avoidance opening 601 from the gap to cause contamination to the driven part 502, reducing the cleaning burden, and improving the linkage stability of the trigger part 401 and the driven part 502. In addition, the setting form of the sealing member 70 is simple, the processing difficulty is low, the cost is low, and it is easy to achieve a good assembly sealing effect.

[0054] Furthermore, the trigger portion 401 is a turn buckle disposed on the side of the cup cover 40, and the sealing member 70 is sleeved on the outside of the turn buckle.

[0055] The trigger part 401 is in the form of a screw button. As the cup cover 40 is screwed in, the trigger part 401 penetrates the avoidance opening 601 in the direction of rotation to trigger the driven part 502. On the one hand, the contact between the trigger part 401 and the driven part 502 is simple in this form. On the other hand, as the trigger part 401 penetrates, the cup cover 40 is reminded to be in place when it is screwed in, which is conducive to the rapid and accurate positioning of the cup cover 40. The trigger part 401 is arranged on the side of the cup cover 40 to avoid the cup cover 40 occupying the crushing chamber space after it is in place. The sealing member 70 is sleeved on the outside of the screw button. As the trigger part 401 penetrates, the sealing member 70 achieves a sealing effect at the avoidance opening 601. Since the cup cover 40 can be removed separately, it is convenient to clean the sealing member 70 sleeved on the outside of the screw button, so that it can be kept clean every time it is used, and a good sealing effect is achieved.

[0056] like Figure 6 , Figure 7 As shown, in one embodiment, the cup cover 40 is screwed together with the grinding cup, and the shielding member 60 is a cover-like structure with an escape opening 601 only along the screw-in direction of the cup cover 40, so that after the cup cover 40 is screwed into place, the trigger part 401 closes the escape opening 601.

[0057] The shielding member 60 is set as a cover-like structure with the avoidance opening 601 only set along the screwing direction of the cup cover 40. When the cup cover 40 is screwed in, the trigger part 401 penetrates the avoidance opening 601 directly during the screwing process, and the trigger part 401 and the driven part 502 are quickly docked. The cover-like structure forms a circumferential protection for the driven part 502 and at least part of the trigger part 401 located inside the shielding member 60. The avoidance opening 601 is closed by the cooperation of the trigger part 401 and the shielding member 60, effectively ensuring the cleanliness of the driven part 502 and avoiding material splashing. It is also convenient for the user to realize the linkage between the trigger part 401 and the driven part 502 with ease when screwing the cup cover 40, thereby improving the user's experience.

[0058] It should be noted that when the shielding member 60 is set as a cover-like structure, the avoidance opening 601 is set on the side of the shielding member 60 corresponding to the direction in which the cup cover 40 is screwed in, so that when the cup cover 40 is screwed in, the trigger part 401 is set to penetrate the avoidance opening 601 during the screwing-in process, thereby quickly realizing the docking of the trigger part 401 and the driven part 502.

[0059] Alternatively, the avoidance opening 601 is located at the top of the shielding member 60 , and the avoidance opening 601 opens upward, further preventing the material in the cup body from splashing into the avoidance opening 601 , thereby achieving a better shielding and protecting effect on the driven part 502 .

[0060] In addition, there are many ways to set the structure of the shielding member 60. In one embodiment, the shielding member 60 is set as an overall L-shaped shielding plate, which also protects the side wall of the driven part 502, effectively ensuring the cleanliness of the driven part 502 and preventing material splashing. In this embodiment, the shielding member 60 can be integrally formed to reduce the installation steps, or it can be split and formed to reduce the difficulty of processing.

[0061] Alternatively, the shielding member 60 is arranged opposite to the inner wall of the cup body 30 to isolate the driven part 502 from the material in the cup body 30 , thereby preventing the material from splashing onto the driven part 502 when the crushing device located at the center of the crushing chamber is working, thereby shielding and protecting the driven part 502 .

[0062] It should be noted that there are many ways for the driven part 502 to extend into the cup body 30 and for the shielding member 60 to be arranged therewith. For details, please refer to the following embodiments:

[0063] Embodiment 1: Figure 8 , Fig. 9 As shown, the grinding cup is provided with a step portion 301 with a step surface 302 facing upward, the step surface 302 is provided with a through hole for the driven portion 502 to pass through, and the shielding member 60 is formed above the step surface 302 .

[0064] The shielding member 60 is partitioned from other components in the pulverizing cup by providing the step portion 301. Since the shielding member 60 is formed above the step surface 302 of the step portion 301, the step portion 301 can shield the material splashing in the pulverizing chamber, further reducing the pulverized material splashing to the shielding member 60, which is beneficial to ensuring the cleanliness of the shielding member 60, further avoiding the adhesion of materials at the avoidance opening 601, and avoiding the material from entering the avoidance opening 601 to contaminate the driven part 502. At the same time, the step portion 301 is provided with a through hole for the driven part 502 to pass through. On the one hand, the through hole enables the driven part 502 to extend into the shielding member 60. On the other hand, the step portion 301 realizes circumferential limiting and supporting effects on the driven part 502 passing through the through hole, which is beneficial to ensuring the stability of the switch connecting rod 50, thereby ensuring the linkage effect between the trigger part 401 and the driven part 502, and ensuring the stable opening of the micro switch 90 and the stable operation of the motor 20.

[0065] Embodiment 2: The connecting rod body 501 extends vertically in the cavity 304 and the driven part 502 extends horizontally into the grinding cavity. The side wall of the grinding cup is provided with a reciprocating hole for the driven part 502 to pass through and reciprocate vertically. The shielding member 60 is formed outside the reciprocating hole.

[0066] The driven part 502 extends laterally into the pulverizing chamber, and forms a bend with the vertical connecting rod body 501 during the lateral extension of the driven part 502, which is beneficial to enhancing the overall stability of the switch connecting rod 50, and the reciprocating hole usually limits the driven part 502 to prevent the driven part 502 from deviating in the vertical direction and causing the laterally extended part to be insufficient for linkage with the trigger part 401, thereby further ensuring the activation stability of the micro switch 90. At the same time, by arranging the driven part 502 to move vertically along the reciprocating hole, the trigger part 401 and the driven part 502 can realize linkage and disengagement. The shielding member 60 is formed on the outside of the reciprocating hole to shield and protect the driven part 502 that extends laterally into the pulverizing chamber, and prevent materials from splashing onto the driven part 502 and causing pollution, thereby further ensuring the action stability of the driven part 502 and ensuring the smooth activation of the micro switch 90.

[0067] like Figure 8 , Fig. 9 As shown, in a preferred embodiment, the cup cover 40 is screwed together with the grinding cup, and the driven part 502 is provided with a guide slope 5021 , and the guide slope 5021 faces the screw-in direction of the trigger part 401 .

[0068] The screwing installation of the cup cover 40 and the crushing cup facilitates the alignment contact between the trigger part 401 and the driven part 502. During the screwing process, the trigger part 401 directly contacts the driven part 502, and the screwing prompt of the cup cover 40 is obvious, which provides a better user experience. A guide slope 5021 facing the trigger part 401 is provided on the driven part 502. When the trigger part 401 is screwed in, the guide slope 5021 guides the linkage cooperation between the trigger part 401 and the driven part 502, so that the trigger part 401 continues to be screwed in along the direction of the guide slope 5021 to achieve linkage with the driven part 502, thereby improving the cooperation efficiency between the trigger part 401 and the driven part 502 and improving the user experience.

[0069] In a preferred embodiment, one of the driven portion 502 and the trigger portion 401 is provided with a rotation-stopping protrusion 4011 , and the other of the two is provided with a rotation-stopping groove 5022 that cooperates with the rotation-stopping protrusion 4011 .

[0070] The stop protrusion 4011 and the stop groove 5022 matched therewith are provided to achieve the limit of the driven part 502 and the trigger part 401 after linkage, so as to prevent the driven part 502 and the trigger part 401 from being separated. When the motor 20 is operated at a high speed, the cup body 30 inevitably shakes, and the shielding member 60 located in the cup body 30 and the shielding member 60 shakes with the cup body 30. The stop protrusion 4011 and the stop groove 5022 prevent the trigger part 401 and the driven part 502 from loosening, and also prevent the cup cover 40 and the cup body 30 from slipping, so as to further ensure the accurate covering position of the cup cover 40 and the cup body 30, and the cooperation of the stop protrusion 4011 and the stop groove 5022 makes the cup cover 40 and the cup body 30 more comfortable to fit, and effectively ensures the triggering effect of the micro switch 90.

[0071] like Fig.10 , Fig.11 As shown, preferably, a stop protrusion 4011 is provided on the trigger part 401, and a stop groove 5022 is provided on the driven part 502. When the trigger part 401 passes through the avoidance opening 601 and cooperates with the driven part 502, the stop protrusion 4011 and the stop groove 5022 are limited in cooperation, so as to avoid the separation of the trigger part 401 and the driven part 502 due to misoperation or shaking, thereby realizing the stable opening of the micro switch 90.

[0072] like Figure 2 , Fig.12 As shown, in a preferred embodiment, the outer wall of the grinding cup is provided with a downward first limiting surface 303, the connecting rod body 501 and the driven part 502 are bent to form an upward second limiting surface 5011, and the first limiting surface 303 and the second limiting surface 5011 are axially limited.

[0073] The connecting rod body 501 is located in the cavity 304, and the limiting of the connecting rod body 501 is achieved through the cooperation between the first limiting surface 303 and the second limiting surface 5011, which is beneficial to ensuring the stable position of the connecting rod body 501, so that the driven part 502 connected thereto can accurately extend into the cup body 30 and link with the trigger part 401, thereby further improving the working stability of the micro switch 90; and the second limiting surface 5011 is formed between the connecting rod body 501 and the driven part 502, and cooperates with the first limiting surface 303 to strengthen the supporting effect on the driven part 502, which is beneficial to ensuring the connection stability between the driven part 502 and the trigger part 401.
