Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a safety mechanism for flipping the lid of a juicer cup and a juicer. Background Technology

[0002] A juicer, a widely used kitchen appliance for juicing fruits and vegetables, typically consists of a base and a juicing device mounted on top of the base. The juicing device mainly includes a jar, a screw installed inside the jar, and a filter. Its working principle involves the screw rotating to apply pressure to the fruit and vegetable raw materials, and the filter separating the juice from the residue. Currently, most juicers on the market use a flip-top jar design. To improve operational safety, these products are usually equipped with a safety mechanism, which typically includes a cam located at the flip-top pivot, a trigger rod located on the side of the jar and movable vertically, and a safety switch located on the base. When the flip-top is closed, the cam at the pivot presses down on the trigger rod, causing it to extend downwards and directly or indirectly trigger the safety switch. At this time, the equipment recognizes that the flip-top is correctly closed, and the base can drive the juicing device normally. Conversely, if the flip-top is open, the trigger rod retracts under the action of an elastic element, the safety switch is not triggered, the equipment determines that the flip-top is not closed, and the juicing device will stop working. However, such safety mechanisms require the flip-top cup to be in the open position during assembly. Since the flip-top cup is screw-on, if the flip-top is closed, the extended trigger rod can easily interfere with surrounding components, preventing successful assembly. In practice, some users, without carefully reading the product manual, may attempt to assemble the cup with the flip-top closed, causing structural interference and preventing assembly. This is often misinterpreted by users as a product malfunction, leading to returns, complaints, or negative reviews, adversely affecting the product's market reputation and sales performance. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a safety mechanism for flipping the lid of a material cup. By setting a two-stage trigger rod, it can realize the screwing and installation of the first material cup regardless of whether the lid is in the open or closed state, achieving a foolproof design and facilitating the user's assembly and use of the product.

[0004] This utility model also proposes a juicer with a safety mechanism for flipping the lid of the juice cup.

[0005] According to a first aspect embodiment of the present invention, a cup flip-top safety mechanism includes a cup assembly, a trigger assembly, and a base cover. The base cover is equipped with a safety switch. The cup assembly is detachably mounted on the base cover and includes a cover body and a screw-on first cup. The cover body is rotatably connected to the first cup and has a cam portion at the rotatable connection. The trigger assembly is located on the side of the first cup and includes a first trigger rod, a second trigger rod, a first elastic element, and a second elastic element. The second trigger rod is movably connected to the lower side of the first trigger rod and can move up and down relative to the first trigger rod. The first elastic element acts on the first cup and the first trigger rod respectively, causing the first trigger rod to have an upward tendency relative to the first cup. The second elastic element acts on the first trigger rod and the second trigger rod respectively, causing the second trigger rod to have a downward tendency relative to the first trigger rod. When the cover body is in a closed state, the cam portion presses down on the first trigger rod, causing the trigger assembly to trigger the safety switch through the second trigger rod.

[0006] According to the embodiment of this utility model, the cup flip-top safety mechanism has at least the following beneficial effects: When the lid is in the open state and the first cup is screwed on, the cam does not press the first trigger rod. The first trigger rod moves upward under the action of the first elastic element and drives the second trigger rod to move upward together, causing the lower end of the second trigger rod to move upward and retract, thereby avoiding interference with surrounding components during assembly and facilitating the smooth assembly and use of the first cup; When the lid is in the closed state and the first cup is screwed on, the cam presses the first trigger rod downward, and the first trigger rod drives the second trigger rod to move downward together. The lower end of the second trigger rod extends downward compared to when the lid is in the open state. Since the second trigger rod can move up and down and is connected to the lower side of the first trigger rod and there is a second elastic element between them, The two trigger rods form an elastic telescopic structure. Therefore, during the screwing-on installation of the first cup, if the lower end of the second trigger rod interferes with the surrounding components, the surrounding components will press the lower end of the second trigger rod. The second trigger rod will then compress the second elastic element and move upward to avoid interference, allowing the first cup to be assembled and used smoothly. During use, if the lid is closed, the cam part presses down on the first trigger rod, causing the triggering component to trigger the safety switch through the second trigger rod, recognizing that the lid is correctly closed. The machine base can then drive the juicing device to operate normally. If the lid is open, the first trigger rod moves upward under the action of the first elastic element, causing the second trigger rod to move upward and retract. The safety switch is not triggered, recognizing that the lid is not closed, and the machine base drives the juicing device to stop working, thus fulfilling the safety function. Through the above structure, the screwing-on installation of the first cup can be achieved regardless of whether the lid is open or closed, achieving a foolproof design and facilitating the user's assembly and use of the product.

[0007] According to some embodiments of the present invention, the upper end of the second trigger rod is movably inserted into the lower end of the first trigger rod.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A safety mechanism for flipping a material cup lid includes a material cup assembly 100, a trigger assembly 200, and a base cover 310. The base cover 310 is equipped with a safety switch 311. The material cup assembly 100 is detachably mounted on the base cover 310 and includes a cover body 110 and a screw-on first material cup 120. The cover body 110 is rotatably connected to the first material cup 120 and has a cam portion 111 at the rotatable connection. The trigger assembly 200 is located on the side of the first material cup 120 and includes a first trigger rod 210, a second trigger rod 220, a first elastic element 230, and a second elastic element 240. The second trigger rod 220 is movably connected to the first trigger rod 240. The lower side of the trigger rod 210 can move up and down relative to the first trigger rod 210. The first elastic element 230 acts on the first cup 120 and the first trigger rod 210 respectively, so that the first trigger rod 210 has a tendency to move upward relative to the first cup 120. The second elastic element 240 acts on the first trigger rod 210 and the second trigger rod 220 respectively, so that the second trigger rod 220 has a tendency to move downward relative to the first trigger rod 210. When the cover 110 is in the closed state, the cam part 111 presses down the first trigger rod 210, so that the trigger assembly 200 triggers the safety switch 311 through the second trigger rod 220.

[0026] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, the upper cover 310 of the machine base is located on the upper side of the main body 320 of the machine base. The cover 110 is rotatably connected to the first material cup 120 and the rotatable position is located in front of the first material cup 120. The cover 110 is provided with a cam part 111 at the rotatable connection. The trigger assembly 200 is located in front of the first material cup 120. The second trigger rod 220 is slidably connected to the lower side of the first trigger rod 210 to form a telescopic structure. The first trigger rod 210 can drive the second trigger rod 220 to move up and down together. The first elastic element 230 and the second elastic element 240 are both springs. The two ends of the first elastic element 230 act on the first material cup 120 and the first trigger rod 210 respectively, so that the first trigger rod 210 has a tendency to move upward relative to the first material cup 120. The two ends of the second elastic element 240 act on the first trigger rod 210 and the second trigger rod 220 respectively, so that the second trigger rod 220 has a tendency to move downward relative to the first trigger rod 210.

[0027] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5When the cover 110 is in the open state and the first cup 120 is screwed on, the cam 111 moves away from the upper side of the first trigger rod 210 and does not press the first trigger rod 210. Under the action of the first elastic element 230, the first trigger rod 210 moves upward and drives the second trigger rod 220 to move upward together, causing the lower end of the second trigger rod 220 to move upward and retract. This avoids interference with surrounding components (such as the protruding structure on the upper side of the base cover 310) during assembly, which is conducive to the smooth assembly and use of the first cup 120. When the cover 110 is in the closed state and the first cup 120 is screwed on, the cam 111 presses the first trigger rod 210 downward. The first trigger rod 210 drives the second trigger rod 220 to move downward together. The lower end of the second trigger rod 220 extends downward compared to when the cover 110 is in the open state. Since the second trigger rod 220 can move up and down and is connected to the lower side of the first trigger rod 210 and is acted upon by the second elastic element 240, the two triggers... The rods form an elastic telescopic structure. Therefore, during the screwing and installation of the first cup 120, when the lower end of the second trigger rod 220 interferes with the surrounding components (such as the protruding structure on the upper side of the base cover 310), the surrounding components press the lower end of the second trigger rod 220. The second trigger rod 220 will compress the second elastic element 240 and move upward to avoid interference, so that the first cup 120 can be assembled and used smoothly. During use, if the cover 110 is in the closed state, the cam part 111 presses down the first trigger rod 210, so that the trigger component 200 triggers the safety switch 311 through the second trigger rod 220, recognizing that the cover 110 is correctly closed. The base can drive the juicing device to operate normally. If the flip cover is in the open state, the first trigger rod 210 moves upward under the action of the first elastic element 230 and drives the second trigger rod 220 to move upward and retract. The safety switch 311 is not triggered, recognizing that the flip cover is not closed. The base drives the juicing device to stop working, thus satisfying the safety use function. With the above structure, the first cup 120 can be screwed on and installed regardless of whether the cover 110 is in the open or closed state, achieving a foolproof design and facilitating the user's assembly and use of the product.

[0028] In practical applications, the safety switch 311 can be a micro switch, pressure sensor, etc., and the specific settings can be made according to the actual needs of use.

[0029] In some embodiments, the upper end of the second trigger rod 220 is movably inserted into the lower end of the first trigger rod 210. One of the first trigger rod 210 and the second trigger rod 220 is provided with a limiting groove 201 extending in the vertical direction, and the other is provided with a limiting part 221. The limiting part 221 is located in the limiting groove 201 and can move up and down along the limiting groove 201 to limit the relative movement stroke between the second trigger rod 220 and the first trigger rod 210.

[0030] Understandably, such as Figure 4 and Figure 5As shown, the upper end of the second trigger rod 220 is movably inserted into the lower end of the first trigger rod 210. The first trigger rod 210 has limiting grooves 201 on both the left and right sides of the upper end of the second trigger rod 220. The limiting grooves 201 extend in the vertical direction. The left and right sides of the upper end of the second trigger rod 220 are correspondingly provided with limiting parts 221. The limiting parts 221 are located in the limiting grooves 201 and can move up and down along the limiting grooves 201 as the second trigger rod 220 moves up and down relative to the first trigger rod 210. The second elastic member 240 is provided at the upper end of the second trigger rod 220, and its two ends abut against the first trigger rod 210 and the second trigger rod 220 respectively, so that the limiting parts 221 abut against the lower side wall of the limiting groove 201. By utilizing the cooperation between the limiting groove 201 and the limiting part 221, the relative movement stroke between the second trigger rod 220 and the first trigger rod 210 is limited, improving the reliability of their relative movement, preventing separation, and facilitating the first trigger rod 210 to drive the second trigger rod 220 to move up or down together. In practical applications, the limiting groove 201 can also be located on the second trigger rod 220, in which case the limiting part 221 is correspondingly located on the first trigger rod 210, and the specific configuration can be changed according to actual usage requirements.

[0031] In some embodiments, one of the first trigger rod 210 and the first cup 120 is provided with a groove 202 extending in the vertical direction, and the other is provided with a connecting part 121. The connecting part 121 is located in the groove 202 and can move up and down along the groove 202. The first elastic member 230 is provided in the groove 202 and acts on the groove wall of the groove 202 and the connecting part 121 respectively.

[0032] Understandably, such as Figure 3 , Figure 4 and Figure 5 As shown, the slide groove 202 is located in the middle of the first trigger rod 210 and extends vertically. The connecting part 121 is located on the front side of the first cup 120 and protrudes forward into the slide groove 202. The first elastic member 230 is located in the slide groove 202, with its upper and lower ends acting on the upper side wall of the slide groove 202 and the connecting part 121, respectively. When the first trigger rod 210 moves vertically relative to the first cup 120, the connecting part 121 moves vertically along the slide groove 202. The cooperation between the slide groove 202 and the connecting part 121 allows for sliding contact between the first trigger rod 210 and the first cup 120, and limits the travel distance of the first trigger rod 210 relative to the first cup 120. Furthermore, it facilitates the assembly and installation of the first elastic member 230, making it easier to use. In practical applications, the slide groove 202 can also be located in the first cup 120, in which case the connecting part 121 is correspondingly located in the first trigger rod 210. The specific arrangement can be changed according to actual usage requirements.

[0033] In some embodiments, the first cup 120 is provided with guide portions 122 on both sides of the trigger assembly 200. The guide portions 122 on both sides of the trigger assembly 200 clamp the first trigger rod 210 and / or the second trigger rod 220 to guide the movement of the first trigger rod 210 and / or the second trigger rod 220 in the vertical direction.

[0034] Understandably, such as Figure 4 and Figure 5 As shown, multiple guide portions 122 are provided and located on both sides of the trigger assembly 200. Parts of the guide portions 122 clamp the first trigger rod 210, and parts of the guide portions 122 clamp the second trigger rod 220, guiding the vertical movement of the first trigger rod 210 and the second trigger rod 220. This helps ensure the reliability and stability of their vertical movement, reduces the possibility of movement deviation, and facilitates use. In practical applications, the specific number, distribution, and structure of the guide portions 122 can be set according to actual usage needs.

[0035] In some embodiments, the upper end of the first trigger rod 210 is provided with a pushing slope 203 corresponding to the cam portion 111. The cam portion 111 can rotate with the cover 110 to abut against the pushing slope 203 and push the first trigger rod 210 downward through the pushing slope 203.

[0036] Understandably, such as Figure 3 and Figure 5 As shown, by providing a pushing slope 203 at the upper end of the first trigger rod 210, a wedge-like structure can be formed between the upper end of the first trigger rod 210 and the cam part 111. When the cam part 111 rotates with the cover 110 to abut against the pushing slope 203, it can easily push the first trigger rod 210 downward through the pushing slope 203, making it convenient to use. In practical applications, the pushing slope 203 can be set according to actual usage needs.

[0037] In some embodiments, the lower end of the second trigger rod 220 is provided with a first guide surface 204, which is an inclined surface or an arc surface, and is used to guide the second trigger rod 220 to move upward when it comes into contact with other components.

[0038] Understandably, such as Figure 4 and Figure 5As shown, the lower end of the second trigger rod 220 is provided with a first guide surface 204. The first guide surface 204 has an inclined structure. When the first material cup 120 is screwed on and installed, if the cover 110 is in the closed state, the lower end of the second trigger rod 220 can abut against the protruding structure or other components on the upper cover 310 of the machine base through the first guide surface 204. Thus, the first guide surface 204 guides the second trigger rod 220 to move upward to avoid obstruction, which is convenient for use. In practical applications, the first guide surface 204 can also be an arc surface structure, which can be set according to the actual use needs.

[0039] In some embodiments, the upper cover 310 of the base is provided with a transmission rod 312 that can move up and down. The transmission rod 312 is located above the safety switch 311. The upper cover 310 of the base is provided with a clearance opening 301. The clearance opening 301 allows the upper end of the transmission rod 312 to extend out of the upper cover 310 of the base and / or allows the lower end of the second trigger rod 220 to extend into the upper cover 310 of the base. When the cover 110 is in the closed state, the second trigger rod 220 can press down the transmission rod 312 and can trigger the safety switch 311 through the transmission rod 312.

[0040] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, the transmission rod 312 is vertically movably connected to the upper cover 310 of the machine base. Its upper end extends out of the upper cover 310 through the clearance opening 301. The lower end of the transmission rod 312 contacts the safety switch 311. Its upper end is provided with a second guide surface 302, which cooperates with the first guide surface 204 to form a wedge structure. This wedge structure guides the second trigger rod 220 to move upward to avoid contact with the lower end of the second trigger rod 220, facilitating its use. After the cup assembly 100 is installed, the lower end of the second trigger rod 220 can abut against the upper end of the transmission rod 312, pressing down the transmission rod 312 to indirectly trigger the safety switch 311. This design allows the safety switch 311 to be positioned more internally, which is beneficial for protecting the safety switch 311. In practical applications, the safety switch 311 can also be located on the upper side of the base cover 310 and triggered directly by the second trigger rod 220. Alternatively, the lower end of the second trigger rod 220 can extend into the base cover 310 through the clearance opening 301 to trigger the safety switch 311. The specific settings can be adjusted according to actual usage needs.

[0041] In some embodiments, the base cover 310 is provided with a surrounding baffle 313 on the upper side of the clearance opening 301. The surrounding baffle 313 is provided around the clearance opening 301 and has a notch for inserting the lower end of the second trigger rod 220.

[0042] Understandably, such as Figure 2 and Figure 3As shown, the edge stop 313 is located above the clearance opening 301, surrounding it and having a notch on the right side to allow the lower end of the second trigger rod 220 to be inserted as the first material cup 120 is screwed into it.
