Technical Field
[0001] This utility model relates to the field of juicer technology, and in particular discloses a mechanically triggered safety protection mechanism for a slow juicer. Background Technology
[0002] Safety is paramount when using a juicer. If a user accidentally touches the rotating juicing blades, it can cause serious personal injury. Some existing juicers lack adequate safety features, with some only having a simple lid, which can easily lead to accidental activation of the blades under unsafe conditions. Therefore, a more reliable safety mechanism is needed to ensure that the juicing blades only start working when all parts of the juicer are correctly installed and properly protected, thus guaranteeing user safety. Utility Model Content
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a mechanically triggered safety protection mechanism for a slow juicer.
[0004] To achieve the above objectives, this utility model provides a mechanically triggered safety protection mechanism for a slow-speed juicer, characterized by: a base, a working chamber, a feeding chamber, and a protective cover; the base is equipped with a drive mechanism, and the working chamber is equipped with a juicing blade; one end of the base near the working chamber is equipped with a reciprocating switch rod and a micro switch that works in conjunction with the switch rod; the working chamber is equipped with a first reciprocating trigger rod, and the feeding chamber is equipped with a second reciprocating trigger rod; the protective cover is equipped with a trigger block; when the working chamber is installed above the base, there is a gap between the first trigger rod and the switch rod; when the feeding chamber is installed above the working chamber, there is a gap between the second trigger rod and the first trigger rod; when the protective cover completely covers the feeding chamber, the trigger block presses down on the second trigger rod, which in turn presses down on the first trigger rod, which in turn presses down on the switch rod, which in turn triggers the micro switch, activating the drive mechanism, which then drives the juicing blade to work.
[0005] Furthermore, the feed hopper is provided with a gripping part, and the protective cover is rotatably connected to one end of the gripping part; the end of the protective cover away from the gripping part is provided with a buckle, and the end of the feed hopper near the protective cover is provided with a protruding ring that cooperates with the buckle. The buckle and the protruding ring cooperate to press and fix the protective cover and the feed hopper together to prevent the trigger block from shifting position.
[0006] Furthermore, the second trigger rod is movably installed on the outer wall of the feed hopper, and a second elastic element for driving the second trigger rod to reset is provided between the second trigger rod and the feed hopper. A first protective shell for covering the second trigger rod is protruding from the outer wall of the feed hopper; the two ends of the grip are respectively connected to the two ends of the first protective shell.
[0007] Furthermore, the first trigger rod is movably mounted on the outer wall of the working chamber, and a first elastic element for driving the first trigger rod to reset is provided between the first trigger rod and the working chamber. A second protective shell protrudes from the outer wall of the working chamber to cover the first trigger rod; the second protective shell has the same width as the first protective shell, which facilitates the alignment of the first trigger rod and the second trigger rod.
[0008] Furthermore, the end of the feeding bin facing the working bin is provided with multiple limiting blocks, and the end of the working bin facing the feeding bin is provided with a limiting groove that matches the limiting blocks. When the feeding bin is placed on the working bin, the feeding bin is rotated to make the limiting blocks engage with the limiting grooves.
[0009] Furthermore, the surface in contact with the first trigger rod is an inclined plane. When the protective cover completely covers the feed hopper, the second trigger rod is pressed down. At this time, when the feed hopper is installed on the working hopper by rotation and snap-fit, the second trigger rod slides and moves above the first trigger rod via the inclined plane, and presses down the first trigger rod.
[0010] Furthermore, the second trigger rod has a body and a limiting rod protruding from the body. The working chamber is provided with a limiting hole that matches the limiting rod. When the second trigger rod presses down on the first trigger rod, the limiting rod is inserted into the limiting hole to limit the positional displacement of the second trigger rod.
[0011] Furthermore, the base has a groove at one end near the working chamber that is adapted to the second protective shell, and the second protective shell is inserted into the groove to align the first trigger rod with the switch rod.
[0012] Furthermore, the end of the base that contacts the working chamber is integrally molded to protect the internal drive mechanism.
[0013] Furthermore, the protective cover also has a feeding port and a feeding guide rod. The feeding port is used to add materials, and the feeding guide rod extends from the feeding port into the feeding bin to guide the materials to be processed into the working bin. A stop ring is provided at the end of the feeding guide rod away from the feeding port to cover the feeding port.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0023] Please see Figures 1 to 6 As shown, this utility model discloses a mechanically triggered safety protection mechanism for a slow juicer, characterized by comprising a base 1, a working chamber 2, a feeding chamber 3, and a protective cover 4. The base 1 is equipped with a drive mechanism, and the working chamber 2 is equipped with a juicing blade. One end of the base 1 near the working chamber 2 is provided with a reciprocating switch rod 11 and a micro switch 12 that cooperates with the switch rod 11. The working chamber 2 is equipped with a first reciprocating trigger rod 21, the feeding chamber 3 is equipped with a second reciprocating trigger rod 31, and the protective cover 4 is equipped with a trigger block 41. When the working chamber 2 is installed above the base 1, there is a gap between the first trigger rod 21 and the switch rod 11. When the feeding chamber 3 is installed above the working chamber 2, there is a gap between the second trigger rod 31 and the first trigger rod 21. When the protective cover 4 completely covers the feeding chamber 3, the trigger block 41 presses down on the second trigger rod 31, the second trigger rod 31 then presses down on the first trigger rod 21, the first trigger rod 21 presses down on the switch rod 11, the switch rod 11 then triggers the micro switch 12. After the drive mechanism is started, the drive mechanism drives the juicing blade to work.
[0024] In actual use, the mechanically triggered safety protection mechanism of this slow juicer mainly includes a base 1, a working chamber 2, a feeding chamber 3, and a protective cover 4. The base 1 is equipped with a drive mechanism, and the working chamber 2 is equipped with a juicing blade. The safety protection function is achieved through the mechanical triggering cooperation between the various components. Only when the working chamber 2, the feeding chamber 3, and the protective cover 4 are installed in place, the trigger block 41 presses down the second trigger rod 31, the second trigger rod 31 then presses down the first trigger rod 21, the first trigger rod 21 presses down the switch rod 11, the switch rod 11 then triggers the micro switch 12, and the drive mechanism can then drive the blade to work.
[0025] Specifically, the feed hopper 3 is provided with a gripping part 32, and the protective cover 4 is rotatably connected to one end of the gripping part 32; the end of the protective cover 4 away from the gripping part 32 is provided with a buckle 42, and the end of the feed hopper 3 near the protective cover 4 is provided with a protruding ring 33 that cooperates with the buckle 42. The buckle 42 and the protruding ring 33 cooperate to press and fix the protective cover 4 and the feed hopper 3 to prevent the trigger block 41 from shifting position.
[0026] In actual use, the protective cover 4 is rotated and installed at one end of the grip part 32. When the protective cover 4 covers the opening of the feed hopper 3, it is pressed and fixed by the buckle 42. At this time, the trigger block 41 presses down the second trigger rod 31 tightly, and will not shift due to vibration, thus affecting the operation of the juicer.
[0027] Specifically, the second trigger rod 31 is movably installed on the outer wall of the feed hopper 3. A second elastic element for driving the second trigger rod 31 to reset is provided between the second trigger rod 31 and the feed hopper 3. A first protective shell 34 for covering the second trigger rod 31 is provided on the outer wall of the feed hopper 3. The two ends of the gripping part 32 are respectively connected to the two ends of the first protective shell 34.
[0028] Specifically, the first trigger rod 21 is movably installed on the outer wall of the working chamber 2. A first elastic element for driving the first trigger rod to reset is provided between the first trigger rod 21 and the working chamber 2. A second protective shell 22 protrudes from the outer wall of the working chamber 2 to cover the first trigger rod 21. The second protective shell 22 has the same width as the first protective shell 34, which facilitates the alignment of the first trigger rod 21 and the second trigger rod 31.
[0029] In actual use, the protective shell not only protects the trigger rod, but also serves as a positioning and guide, making it convenient for users to install the feed hopper 3 and the working hopper 2. When the first protective shell 34 and the second protective shell 22 are aligned, the second trigger rod 31 and the first trigger rod 21 are aligned, which facilitates the transmission between the protective mechanism components.
[0030] Specifically, the feeding bin 3 has a plurality of limiting blocks 35 protruding from one end facing the working bin 2, and the working bin 2 has a limiting groove 23 that matches the limiting blocks 35 at one end facing the feeding bin 3. When the feeding bin 3 is placed on the working bin 2, the feeding bin 3 is rotated to make the limiting blocks 35 engage with the limiting groove 23.
[0031] In actual use, the feeding chamber 3 and the working chamber 2 are respectively equipped with a limiting block 35 and a limiting groove 23. When the feeding chamber 3 is installed on the working chamber 2, the limiting block 35 and the limiting groove 23 are engaged by rotation in a specific direction, so that the feeding chamber 3 and the working chamber 2 are tightly installed and will not shift position during the operation of the juicer. When the feeding chamber 3 and the working chamber 2 are installed in place, the first protective shell 34 and the second protective shell 22 are aligned and connected, and the first trigger rod 21 and the second trigger rod 31 inside are simultaneously aligned.
[0032] Specifically, the surface of the second trigger rod 31 that contacts the first trigger rod 21 is an inclined surface. When the protective cover 4 completely covers the feed hopper 3, the second trigger rod 31 is pressed down. At this time, when the feed hopper 3 is installed on the working hopper 2 by rotating and snapping, the second trigger rod 31 slides and moves above the first trigger rod 21 via the inclined surface and presses down the first trigger rod 21.
[0033] In actual use, users can first add the material to be processed to the feeding hopper 3, cover the protective cover 4, and then install the feeding hopper 3 to the working hopper 2. At this time, the second trigger rod 31 is pressed down by the trigger block 41 and extends out of the first protective shell 34. The side of the second trigger rod 31 that contacts the first trigger rod 21 is an inclined surface. As the feeding hopper 3 is installed to the working hopper 2 by rotation, the second trigger rod 31 slides synchronously over the first trigger rod 21 via the inclined surface and presses down the first trigger rod 21.
[0034] Specifically, the second trigger rod 31 has a body and a limiting rod 311 protruding from the body. The working chamber 2 is provided with a limiting hole 24 that matches the limiting rod 311. When the second trigger rod 31 presses down on the first trigger rod 21, the limiting rod 311 is inserted into the limiting hole 24 to limit the positional displacement of the second trigger rod 31.
[0035] In actual use, the second trigger rod 31 is also provided with a limit rod 311 in parallel. When the second trigger rod 31 presses down on the first trigger rod 21, the limit rod 311 is inserted into the limit hole 24 on the working chamber 2 to prevent the position of the second trigger rod 31 from shifting when the juicer is working, causing the first trigger rod 21 to pop out, thereby affecting the operation of the juicer.
[0036] Specifically, the base 1 has a groove 13 at one end near the working chamber 2 that is adapted to the second protective shell (22). The second protective shell 22 is inserted into the groove 13 so that the first trigger rod 21 is aligned with the switch rod 11.
[0037] In actual use, the base 1 is provided with a groove 13 that is adapted to the second protective shell 22 of the working chamber 2. When the working chamber 2 is installed on the base 1, the second protective shell 22 is simply aligned with the groove 13.
[0038] Specifically, the end of the base 1 that contacts the working chamber 2 is integrally formed to protect the internal drive mechanism.
[0039] In actual use, the end of the base 1 facing the working chamber 2 is integrally formed. This design can prevent juice and residue in the working chamber 2 from entering the base 1, affecting the operation of the drive mechanism, and preventing circuit damage.
[0040] Specifically, the protective cover 4 also has a feeding port 43 and a feeding guide rod 44. The feeding port 43 is used to add materials, and the feeding guide rod 44 extends from the feeding port 43 into the feeding bin 3 to guide the materials to be processed into the working bin 2. A stop ring 441 protrudes from the end of the feeding guide rod 44 away from the feeding port 43 to cover the feeding port 43.
[0041] In actual use, when the juicer is working and you need to add fruit or other items, you can add them through the feeding port 43 to avoid frequently opening and closing the protective cover 4. After adding the ingredients, insert the feeding guide rod 44 into the feeding chamber 3 through the feeding port 43. The stop ring 441 can cover the feeding port 43 to prevent liquid from splashing out or dust from falling in. At the same time, the feeding guide rod 44 can also guide the items to be processed into the working chamber 2, improving the working efficiency of the juicer.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
