Description

Technical Field

[0001] The present invention relates to the technical field of food processing devices, and specifically, mainly relates to a safety switch structure of a food processor and its usage method. Background Art

[0002] With the continuous and rapid development of the economic society, the living standards of the people have been continuously improved, and people's diet has also been greatly improved. A variety of food processing appliances have increasingly entered the kitchens of modern families, such as juicers, blenders, wall breakers, egg beaters, etc. The use of these kitchen appliances makes the processing of food more and more convenient.

[0003] A food processor with a crushing function is a kind of kitchen food processing appliance. This kind of food processor usually has a mixing cup for accommodating food materials. A sharp blade is installed at the bottom of the mixing cup for crushing food materials. The blade is driven by a motor. When working, the user connects the power supply to the food processor. After the motor is powered on, it can drive the blade to rotate at a high speed to break up the food materials.

[0004] In the prior art, generally, in order to protect the personal safety of the users, the mixing cup is equipped with a lid. When the lid is covered on the mixing cup, it can isolate the user's body from the high-speed rotating blade and prevent the crushed food materials from splashing out of the mixing cup, thus ensuring the personal safety of the user. However, if the lid is not properly covered on the mixing cup, this safety guarantee will no longer exist.

[0005] As mentioned above, the existing food processor products need to cover the lid in place to ensure the personal safety of the users. However, on the premise that the lid is not covered in place, the motor can still be normally started to drive the blade to work, which still has great danger. Therefore, it needs to be improved.

Placing the cup body 11 on the upper part of the base 31 and rotating the cup body 11 can screw the clamping convex blocks 113 into the positioning grooves 341 and enable the positioning protrusions 342 to enter the clamping grooves 1131, so as to detachably lock the position of the cup body 11 on the positioning seat 34 and ensure the stability of the cup body 11 during operation.

[0049] Referring to Figure 4 and Figure 8The transmission assembly 4 includes a connecting member 41, a trigger member 42, a reset member 43 and a return member 44, wherein the connecting member 41 includes a connecting body 411 and a push plate 414, the connecting body 411 is an arc-shaped structure, and the connecting body 411 is installed in the cavity formed between the handle 12 and the handle cover 13, and a sliding groove 417 is provided at the upper end of the connecting body 411, and a sliding rib 412 is fixed on the side of the connecting body 411 away from the handle 12; accordingly, the side of the cup body 11 A guide bar 115 is integrally fixed on the wall. The guide bar 115 is arranged above the upper end of the handle 12 and between the handle cover 13 and the handle 12. The guide bar 115 is passed through the sliding groove 417 so that the connecting body 411 and the cup body 11 can slide relative to each other. In addition, a limiting groove 131 is provided on the side of the handle cover 13 facing the handle 12, and the sliding rib 412 is passed through the limiting groove 131 so that the connecting body 411 and the handle cover 13 can also slide relative to each other.

[0050] Reference Figure 4 A plurality of ribs 419 are fixedly arranged between the connecting body 411 and the sliding rib 412, which are used to assist in fixing the sliding rib 412 so that the sliding rib 412 and the connecting body 411 can form a whole; a pair of limiting plates 121 are fixedly arranged on the side of the handle 12 away from the cup body 11, and the connecting body 411 is arranged between the two limiting plates 121, so that the limiting plates 121 can limit the position of the connecting body 411, ensuring that the connecting body 411 can stably slide between the handle 12 and the handle cover 13.

[0051] Reference Figure 4 The pushing plate 414 is an L-shaped bending plate and is fixed to the lower end of the connecting body 411. The pushing plate 414 is bent downward; a docking cavity 112 is integrally provided on the cup body 11, and the docking cavity 112 is arranged below the lower end of the handle 12. The docking cavity 112 has an opening on the cup body 11, and the position of the opening is arranged between the two positioning slots 114. A connecting hole 1121 is provided on the side wall of the docking cavity 112, and the connecting hole 1121 connects the docking cavity 112 with the interior of the cup body 11. The connecting hole 1121 opens toward the lower end of the cup body 11, and the downwardly bent part of the pushing plate 414 passes through the connecting hole 1121.

[0052] Reference Figure 4, in order to limit the sliding range of the connecting body 411, two baffles 122 are fixedly arranged at the upper end of the handle 12. The connecting body 411 is arranged between the two baffles 122. In addition, limiting blocks 418 are fixedly arranged on both sides of the connecting body 411. The limiting blocks 418 are arranged below the baffles 122 and correspond to the baffles 122 up and down. Thus, when the limiting blocks 418 contact the baffles 122, the connecting body 411 slides upward to the limit position. In addition, a limiting post 415 is fixedly arranged on the pushing plate 414. The limiting post 415 is arranged inside the docking cavity 112. Thus, when the end of the limiting post 415 contacts the side wall of the docking cavity 112, the connecting body 411 slides downward to the limit position.

[0053] Referring to Figure 4 and Figure 7 , a pushing port 36 is formed in the connecting seat 33 of the machine base assembly 3. The pushing port 36 penetrates through the connecting seat 33 and the base 31, so that the inner cavity of the base 31 is communicated with the upper part. When the cup body 11 is locked on the positioning seat 34 by rotating the cup body 11, the bent-down part of the pushing plate 414 can enter the pushing port 36.

[0054] Referring to Figure 7 and Figure 8 , the trigger member 42 includes a rod body 421, a pushed plate 422, a contact head 423 and limiting claws 424. The rod body 421 is in a long strip structure. The rod body 421 is arranged in the inner cavity of the base 31. The pushed plate 422 is fixed to the upper end of the rod body 421, and the pushed plate 422 passes through the pushing port 36. After the pushing plate 414 of the connecting member 41 enters the pushing port 36, it can apply a downward thrust on the pushed plate 422, thereby driving the trigger member 42 to move downward; a guiding bevel 4221 is arranged on the pushed plate 422. During the process of the pushing plate 414 entering the pushing port 36, the guiding bevel 4221 has the function of guiding the pushing plate 414 to smoothly push the pushed plate 422 downward.

[0055] Referring to Figure 8 , the contact head 423 is fixed to the lower end of the rod body 421. There are two limiting claws 424, and they are respectively fixed on both sides of the rod body 421; a middle hole 351 is formed in the switch seat 35, and a clamping hole 352 is formed on each side of the middle hole 351. The contact head 423 passes through the middle hole 351, and the end of the contact head 423 corresponds to the control switch 5 up and down; in this embodiment, the reset member 43 adopts a reset spring. The reset spring is sleeved on the contact head 423, and one end of the reset spring abuts against the rod body 421, and the other end abuts against the switch seat 35. The two limiting claws 424 are respectively inserted into the two clamping holes 352. The end of the limiting claw 424 is provided with a barb, which can prevent the contact head 423 from disengaging from the middle hole 351.

[0056] Referring to Figure 2 and Figure 4A push piece 211 is fixedly provided on the lower surface of the cover body 21. The push piece 211 is a plate-shaped structure. A guide chamfer 2111 is provided at the lower part of the push piece 211. A check block 2112 is also provided at the lower part of the push piece 211. Correspondingly, a clearance gap 124 is provided at the upper end of the handle 12 for the push piece 211 to enter. When the cup body 11 is locked on the positioning seat 34, when the user installs the cover body 21 at the opening at the upper end of the cup body 11, the push piece 211 is pushed into the clearance gap 124 by rotating the cover body 21, so that the push piece 211 can apply a downward thrust to the connecting body 411, thereby causing the connecting body 411 to push the trigger member 42 to trigger the control switch 5.

[0057] Reference Figure 2 and Figure 5 A slot 416 is also provided at the upper end of the connecting body 411 for the non-return protrusion 2112 to enter. When the cover body 21 is rotated to allow the push piece 211 to enter the clearance gap 124 and the push piece 211 is pressed against the edge of the clearance gap 124, the non-return protrusion 2112 enters the slot 416 and presses against the side wall of the slot 416. At this time, the contact 423 of the trigger member 42 is in the lower limit position, and the connecting body 411 cannot move downward. The position of the non-return protrusion 2112 is restricted by the slot 416. The user cannot rotate the cover body 21 in the opposite direction to disengage the non-return protrusion 2112 from the slot 416, and thus cannot remove the cover body 21 from the cup body 11, which is beneficial to ensuring the personal safety of the user.

[0058] Reference Figure 2 and Figure 5 When the non-return protrusion 2112 is in the slot 416, in order to remove the cover body 21 from the cup body 11, the user needs to first remove the cup body 11 from the positioning seat 34. The connecting body 411 will slide downward under the action of gravity, and the slot 416 will automatically separate from the non-return protrusion 2112. At this time, rotating the cover body 21 can rotate the push piece 211 out of the clearance notch 124. When the locking ear 212 on the cover body 21 is separated from the limiting strip 111 on the cup body 11, the cover body 21 can be removed from the cup body 11.

[0059] Reference Figure 4 and Figure 5 A positioning column 413 is fixedly provided at the upper end of the connecting body 411. In this embodiment, the return member 44 adopts a return spring, and the return spring is sleeved on the positioning column 413. One end of the return spring contacts the handle cover 13, and the other end contacts the connecting body 411. Therefore, when the cup body 11 is removed from the positioning seat 34, the return spring can apply a thrust to the connecting body 411, so that the connecting body 411 slides downward smoothly, ensuring that the slot 416 is smoothly separated from the non-return protrusion 2112, thereby ensuring that the user can remove the cover body 21 from the cup body 11.

[0060] The embodiments of the present application also disclose a method for using a safety switch structure of a food processor, which is used to operate the above-mentioned safety switch structure of the food processor, and includes the following steps:

[0061] Step 1: Place the cup body 11 on the upper part of the base 31, and rotate the cup body 11 so that the clamping convex block 113 enters the positioning groove 341 until the positioning protrusion 342 is clamped into the clamping groove 1131.

[0062] Step 2: Cover the cover body 21 at the opening of the cup body 11, and rotate the cover body 21 so that the limiting strip 111 enters the locking ear 212 until the locking protrusion 2121 is clamped into the limiting groove 1111.

[0063] Step 3: Rotate the cup body 11, and after the clamping convex block 113 is rotated out of the positioning groove 341, remove the cup body 11 from the base 31.

[0064] Step 4: Rotate the cover body 21, and after the limiting strip 111 is separated from the locking ear 212, remove the cover body 21 from the opening of the cup body 11.

[0065] The above steps are respectively used to achieve different functions:

[0066] The purpose of Step 1 is to lock the cup body 11 on the positioning seat 34, so that the push plate 414 enters the push port 36 and contacts the pushed plate 422. At this time, due to the action of the return spring, the force of the push plate 414 pushing the pushed plate 422 downward is not enough to make the contact 423 contact the control switch 5.

[0067] The purpose of Step 2 is to lock the cover body 21 on the cup body 11, so that the push piece 211 enters the relief notch 124 and applies a downward thrust to the connecting body 411, so that the connecting body 411 drives the push plate 414 to push the pushed plate 422 downward, and further makes the contact 423 contact the control switch 5 to turn on the control switch 5.

[0068] The purposes of Step 3 and Step 4 are to enable the user to remove the cover body 21 from the cup body 11.

[0069] If the order of Step 1 and Step 2 is interchanged, the control switch 5 can be directly triggered after the cup body 11 is locked on the positioning seat 34 to achieve the same function.

[0070] The order of Step 3 and Step 4 cannot be interchanged because under the condition that the cup body 11 is locked on the positioning seat 34, the check convex block 2112 of the push piece 211 is stuck in the card slot 416 of the connecting piece 41, and the connecting piece 41 has no margin for downward movement. Therefore, the user cannot rotate the cover body 21.

[0071] In summary, the present invention can achieve the following functions:

[0072] If only the cup body 11 is installed on the base 31 and the positioning seat 34, and the cover body 21 is not installed on the cup body 11, the control switch 5 cannot be triggered and the food processor cannot be started.

[0073] Under the condition that the cup body 11 is locked on the positioning seat 34, after the cover body 21 is properly installed on the cup body 11, the control switch 5 can be triggered to power on the food processor. At this time, the cover body 21 cannot be separately removed from the cup body 11. If the cover body 21 needs to be removed, the cup body 11 must be removed from the base 31 first.

[0074] If the cover body 21 is installed on the cup body 11 but not locked in place, or if the cup body 11 is installed on the base 31 and the positioning seat 34 but not locked in place, the control switch 5 cannot be triggered and the food processor cannot be started.

[0075] The above functions are all beneficial to protecting the user's body from harm and improving the safety of the food processor.

[0076] In addition, the above usage method allows the user to activate the control switch 5 of the food processor and disassemble and assemble the cup body 11 and the cover body 21 under the condition of ensuring the personal safety of the user.

[0077] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
