[0036] As attached Figure 1-6 As shown, this application provides an interlocking switch through the following technical solution, including:

[0037] Pressing part 1, with button 11 inside, button 11 can move horizontally inside pressing part 1 under the action of external force;

[0038] Switching part 2, the switching part 2 is provided with micro switch 21, the micro switch 21 is provided with contact 211, the switching part 2 can move vertically between a first position and a second position under the action of external force;

[0039] When the switch part 2 moves to the second position, the contact 211 of the micro switch 21 is horizontally aligned with the button 11. After the button 11 is pressed, it moves and can contact the contact 211 of the micro switch 21.

[0040] Compared with the prior art, the switch part 2 of the interlocking switch moves vertically in the first and second positions under the action of external force. In the second position, the button 11 can be pressed and moved horizontally to activate the contact 211 of the micro switch 21 to start the coffee grinder. The button 11 does not need to be provided with an additional protrusion and can be flush with the outer wall of the coffee grinder. Moreover, the travel of the button 11 is inside the coffee grinder rather than on the surface of the coffee grinder, which reduces the impact on the appearance and internal space of the coffee grinder, which is conducive to the miniaturization of the coffee grinder and also improves the aesthetics of the coffee grinder.

[0041] In the technical solution of this embodiment, the switch part 2 includes a pressure rod 22, a switch base 23, and a connecting seat 24. The pressure rod 22 is disposed above the switch base 23, and the connecting seat 24 is disposed between the pressure rod 22 and the switch base 23. The connecting seat 24 is provided with a connecting hole 241. The bottom end of the pressure rod 22 is provided with a first guide post 221, and the top of the switch base 23 is provided with a second guide post 231 opposite to the first guide post 221. The first guide post 221 and the second guide post 231 extend into the connecting hole 241 from the upper and lower ends of the connecting hole 241 respectively and abut against each other. The micro switch 21 is disposed in the switch base 23. The pressure rod 22 is pressed down under the action of external force, and the first guide post 221 presses the second guide post 231, thereby driving the switch base 23 to move downward.

[0042] When the coffee grinder is disassembled or not installed correctly, the pressure lever 22 is in a released, unpressurized state. At this time, the switch part 22 is in the first position, and the contact 211 of the corresponding micro switch 21 is located above the horizontal line of the button 11. Even if the button 11 is pressed, it cannot contact the contact 211 of the micro switch 21, ensuring that the coffee grinder cannot be started when disassembled or not installed correctly. After the coffee grinder is installed correctly, the pressure lever 22 is pressed, and the first guide post 221 presses the second guide post 231, thereby driving the switch base 23 to move downward to the second position. The contact 211 of the micro switch 21 is horizontally aligned with the button 11. At this time, pressing the button 11 will contact the contact 211 of the micro switch 21, starting the coffee grinder.

[0043] Specifically, a first elastic element 222 is sleeved on the first guide post 221. The two ends of the first elastic element 222 abut against the upper surface of the connecting seat 23 and the lower surface of the pressure rod 22, respectively. When the external force on the pressure rod 22 disappears, the pressure rod 22 can return to the first position under the action of the rebound force of the first elastic element 222.

[0044] Specifically, a third guide post 236 is provided on the top of the switch base 23, and a clearance hole 242 is provided on the connecting seat 24. The third guide post 236 passes through and protrudes from the clearance hole 242. When the switch base 23 moves under the drive of the top rod 22, the third guide post 236 moves synchronously in the clearance hole 242 to ensure the stability and accuracy of the movement of the switch base 23. In addition, a second elastic element 232 is sleeved on the third guide post 236, and a stop 233 is provided at the exposed end of the third guide post 236. The two ends of the second elastic element 232 abut against the upper surface of the connecting seat 24 and the lower surface of the stop 233, respectively. When the switch seat 23 moves downward under the action of the pressure rod 22, the stop 233 compresses the second elastic element 232 simultaneously. When the external force on the pressure rod 22 disappears and returns to the first position under the action of the rebound force of the first elastic element 222, the switch seat 23 also returns to the first position under the elastic force of the second elastic element 232, and maintains the contact between the second guide post 231 and the first guide post 221.

[0045] In this embodiment, there is a pair of third guide posts 236 and a pair of clearance holes 242. The third guide posts 236 are located on both sides of the second guide posts 231, and the clearance holes 242 are located on both sides of the connecting holes 241. In this way, at least three connection structures are formed between the third guide posts 236, the second guide posts 231, the clearance holes 242, and the connecting holes 241. When the pressure rod 22 and the switch base 23 move relative to each other, they can maintain good stability and accuracy in the moving direction and horizontal direction, accurately moving to the first position and the second position. When the switch base 23 reaches the second position, it ensures that the contact 211 of the micro switch 21 is horizontally aligned with the button 11, thereby ensuring that the button 11 can effectively actuate the contact 211 of the micro switch 21 after being pressed, thus starting the grinder.

[0046] It should be noted that the first elastic element 222 and the second elastic element 232 are springs, and the stop element 233 is a washer screw. Installation can be completed by screwing it into the exposed end of the third guide post 236.

[0047] In the technical solution of this embodiment, the pressing part 1 further includes a limiting component 12. The limiting component 12 includes at least one slot 121, and the button 11 includes at least one locking block 111 that cooperates with the slot 121. The locking block 111 is engaged in the slot 121 and can move horizontally within the slot 121, thereby realizing the movable connection between the button 11 and the limiting component 12, so that the button 11 can move horizontally within the pressing part 1 after being pressed. A third elastic element 13 is also provided between the button 11 and the limiting component 12. After the button 11 is pressed into the contact 211 of the micro switch 21 and the grinder is started, the button 11 can be released. The button 11 can be reset under the elastic force of the third elastic element 13. The grinder can be started with a single press, which is relatively simple to operate. Meanwhile, the button 11 for pressing to start does not need to have any extra protrusion and can be flush with the surface of the grinder. Moreover, the travel of the button 11 is mainly inside the grinder, rather than on the surface, so it has little impact on the appearance and internal space of the grinder, making it easier to reduce the size of the grinder and improve its aesthetic uniformity.

[0048] In this embodiment, the limiting component 12 is provided with a groove 122 on the side facing the switch part 2, and the switch part 2 is provided with a slider 234 on the side facing the limiting component 12. The slider 234 is slidably connected to the groove 122. The top of the slider 234 is provided with a vertically downward protruding tooth 235, and the end of the groove 122 is provided with a toothed groove 123. When the switch part 2 moves to the second position, when the button 11 is pressed and moves to contact the contact 211 of the micro switch 21, the protruding tooth 235 is coupled with the toothed groove 123 to limit the movement of the switch base 23 along the pressing direction of the button 11, so as to ensure that the contact 211 of the micro switch 21 is in full contact with the button 11.

[0049] This application also provides a coffee grinder, including a body 3, the body 3 having a detachable top cover 31, a pressing part 1 disposed on the side wall of the body 3, and a switch part 2 disposed inside the body 3. A connecting seat 24 is fixedly connected to the body 3, and the top end of a pressure lever 22 is disposed at the mounting position of the top cover 31. When the top cover 31 is removed or not correctly installed, the pressure lever 22 is in a released, unpressurized state, and the switch part 1 is in a first position. After the top cover 31 is correctly installed, pressing the pressure lever 22 causes the switch seat 23 to move downwards to a second position, thereby pressing the button 11 to start the coffee grinder.
